ABSTRACT: A feeding trial was conducted to evaluate the effect of inclusion level of cooked Delonix regia seed meal

(CDRM) in the practical diet of Oreochromis niloticus fingerlings through their growth performance and nutrient

utilization for 56 days. Four iso-nitrogenous and iso-lipidic experimental diets were formulated to contain 35% crude

protein and 9.5% lipid, CDRM was included at different varying inclusion levels viz: 0, 10, 15 and 20 and were designated

as D1 (0 % inclusion), D2 (10 % inclusion), D3 (15 % inclusion) and D4 (20 % inclusion). Each treatment was allocated to

three tanks of twenty O.niloticus per tank with initial mean weight of 1.18±0.10g. There was no significant difference

(P>0.05) in the survival rate of all the treatments, D2 has the highest value in percentage weight gain, specific growth rate,

feed intake, protein efficiency and protein retention, while D4 (20% inclusion) had the lowest value in all the growth

parameters and feed utilization measured. However, there is no significant difference (P>0.05) between fish fed D3 (15%

inclusion) and D1 (control: 0% inclusion). Proximate composition result revealed that increase in the inclusion level of

cooked Delonix regia lead to an increase in carcass lipid content and a decrease in the moisture content of the fish fed

experimental diet. The results indicate 10-15% inclusion of Delonix regia seed meal improved growth performance and

nutrient utilization of Nile tilapia fingerlings.

Key words: Oreochromis niloticus; Growth performance; Delonix regia;

ABSTRACT: The aim of this study was to examine the impact of haemoglobin variants HbAS and HbAC on

asymptomatic malaria compared to normal HbAA among adults living in a malaria hyperendemic area. Seemingly healthy

individuals, 2,237 (≥16 years) without clinical symptoms in Iwo, Southwestern Nigeria were screened for this study after

informed consent was obtained. A sample of 5 mL of blood was withdrawn from each participant for examination of

malaria parasite and haemoglobin genotype. Thick and thin Giemsa stained blood smear were prepared for malaria parasite

identification and quantification. Haemoglobin genotype was determined by cellulose acetate electrophoresis. The results

showed that compared to HbAA, malaria infection and parasite densities were significantly lower in Hb AS (ᵡ2 = 26.66, p <

0.001; t = 5.05, p < 0.001) and HbAC (ᵡ2

= 6.51, p = 0.01; t = 3.70, p = 0.002). However, there was no significant

difference between HbAS and HbAC individuals with respect to malaria infection and parasite density (ᵡ2 = 0.21, p = 0.64;

t = 0.22, p = 0.83). These findings suggested that among adults living in Iwo, Southwestern Nigeria, HbAS or HbAC

offered better protection against asymptomatic falciparum malaria infection than HbAA while HbAS and HbAC offered

similar protection.

Key Words: asymptomatic falciparum malaria; haemoglobin electrophoresis

ABSTRACT : The purpose of this paper is to propose a conceptual model which would provide a better understanding on

how social influences through the effect of peer communication could interplay with materialism to capture the effect of

young adults’ adoption of technological innovation in their life. This paper provides a brief review on the theories

associated with the adoption of technological innovation as well as some important empirical findings to support the model

of this study. Based on a review of established studies this paper re-examined the relationship between peer

communication and the adoption of technological innovations and propose that young adults’ interaction with their peers

have significant positive effect in their adoption of technological innovation. However, this paper argues that the effect is

not direct. This paper proposes that the relationship between peer communication and the adoption of technological

innovation could be indirect, through the relative mediating effect of materialism. Next, the relationship between

materialism and the adoption of technological innovation is examined as well as how the antecedents of materialism.

Finally, the paper concludes with a discussion on the limitations and the possible areas of research which researchers could

explore in the future.

Key Words: Young adult consumers, peer communication, materialism, adoption of technological innovation.

ABSTRACT:Essential amino acids such as methionine have been increasingly included into diets of lambs. However, few

studies have determined the effects of methionine supplementation in the general performance and economic returns of

lamb production. To address this question, 21 weaned male Rahmani lambs were allotted to 3 dietary treatments: control

diet (C), control diet plus 3.30 g of methionine/kg concentrate feed mixture (T1), and control diet plus 3.63 g of

methionine/kg concentrate feed mixture (T2). T1-fed lambs showed significantly higher (P < 0.05) total body weight gain

than those fed diets C. The digestibility coefficients of dry matter (DM), organic matter (OM), crude protein (CP), ether

extract, (EE), and nitrogen free extract (NFE) for T1 and T2 were significantly better (P < 0.05) than for C. Economically,

dietary feed T1 and T2 increased the net profit by 329.64 Egyptian pounds (EGP)/lamb and 305.76 EGP/lamb,

respectively, as compared with the control diet. In addition, the economic efficiency (average feed cost/kg of body weight

gain) was 10.02 for C and T1 and 10.48 for T2. Total costs were similar between the 3 dietary treatments. In conclusion,

feeding growing Rahmani lambs with 3.30 g of methionine/kg concentrate feed mixture improved their growth

performance and raised their economic value.

Abstract

When the courts of a country encounter with a legal relationship in which there is a foreign element, conflict of law issue

arises. It means that the court must decide which of the proposed law will apply.During the last few decades party

autonomy has become a topic of discussion in this area, especially in family matters. Often, the admission of party

autonomy can be explained by the need for conflict of law certainty, especially in the areas of international matrimonial

property and internationalsuccession, but another area that can be considered in relation to party autonomy in international

trade law is a contract. What this article will be considered is party autonomy, according to Iranian law, in particular with

regard to the provisions of some European countries in this regard and expressed its limitations.

Abstract

With the progress of human societies, trade turnover has exceeded the border. The complexity and diversity of the

different cultures and the lack of a common language that everyone with any intellectual profession adhere to its

rules and legal topics in a different name, remember it is not sensible. Despite the similarities that soft law and legal

norms And sometimes mistakenly used interchangeably, This comparison differences between them and the

territory of any one of them is described briefly.In a sense, the non-binding soft law documents and

recommendations that are not legal binding stage but the power of flexible benefit and the norms of legal rules and

principles, and sometimes the custom in our country is different. In other words, it can be said While in some

respects the rights norms obsolete, but in the creation and formation of soft law and the law play a major role.Of

course, the same basic principles and legal norms that have become the universal rule Unfortunately, despite being

written and binding independent states are not in a single article And even chapter does not have in their laws.

Through this relationship we want to have someone who was paid to it from this perspective Step in developing

effective legal norms and unification of private law, especially in the field of international trade survey. Take a look

back to the place that is the source of rights.

Abstract

The upward trend of global warming has increased the use of renewable energy, based on distributed generation sources

(DGS) for power generation. This study proposes a new load distribution algorithm in which the system frequency and

bus voltage of distributed generation sources are studied as load distribution variables. In addition, the performance of

distributed generation sources in controlled mode and constant power, performance of production resources Dispersions

are modeled on the basis of the control mode and the frequency of the network is used to supply the load between

distributed generation sources. These equations are solved by an improved optimization method. The objective function

used for the load distribution problem is to minimize the imbalance between production and demand in the network. The

results are plotted on two 6 bass networks, 69 buses, to show the validity of the proposed algorithm.

Abstract

What is currently known as suburbanization is no more than an old and historic process of migration by a group of people

seeking work and welfare and those escaping from villages and small cities due to their repulsions and the fact that the

poor are driven out from there to cities, particularly to the suburban areas. Hence, the emergence of suburbanization in

both Iran and the world has been accompanied by migration and its consequences. The formation of widespread

suburbanization in Iran in 1970s has been concurrent to increased migration of villagers to cities; i.e. when, on the one

hand, the expansion of urban facilities and communication networks as well as increased oil revenues had resulted in the

prosperity of cities and creation of urban attractions, and on the other hand, land reforms and agricultural mechanization

and inattention to basic transformations in villages and agriculture sector had aggravated rural repulsions. In this

connection, most migrants who could not afford to settle in the official limits of cities and could not cope with housing and

residence incurred costs in the legal areas of cities turned to the suburban areas for sheltering themselves.

Suburbanization is a product of life in the city which differs fundamentally with neighboring parts in terms of political,

social, cultural, economic, structural and legal aspects and history of settlement and development of historic processes.

Suburbanization is characterized by unordinary street houses, narrow alleys, health and environmental problems, increased

rate of population, cultural poverty and high vulnerability against natural disasters, low level of facilities and life

amenities, unofficial jobs as predominant employment, illegal land seizures, etc. Hence, one can say that suburbanization

is an example of social ills and deviance followed by such consequences as insecurity, development dysfunction and lack

of progress in the country as a whole. In this paper, after investigating rural migration in Iran followed by the way

suburbanization was formed, suburbanization features are divided into three physical, social and economic aspects based

on the researches done, and the article concerns with ills from suburbanization, including social and cultural ills, economic

ills, structural ills, environmental ills, security ills and political ills. In the end, guidelines and recommendations in three

strategies of prevention, empowerment and culture-building are provided based on the causes of formation of

suburbanization and the resulting ills.

Abstract

In research using a set of transaction records from the futures Exchange, risk-taking behavior subject and the house money

and break-even effects study for various trader types. The empirical results show that the degree of morning gains/losses

nonlinearly influences afternoon risk taking for trader types, but the pattern is different for each type. Active individuals

exhibit a house money effect after experiencing large gains and exhibit a break-even effect after large and small losses.

Futures proprietary firms exhibit a break-even effect only after experiencing large morning losses. The additional risk-

seeking behaviors of futures proprietary firms and foreign institutions do not have a significant influence on market

volatility or liquidity; only active individuals' risk-seeking behaviors when facing large morning losses impact both market

volatility and liquidity.

Abstract Arbitration is a private dispute resolution authority that has been considered in the Iranian Civil Procedure Code .

According to Article 472 of the Code of Civil Procedure, arbitration is binding contract and, therefore, neither of the

parties can terminate it. Also under paragraph 2 of article 481 arbitration terminates by the death or motive of either party.

It is also said that if the subject matter of the arbitration is ruled out in a direction, the arbitration will also be excluded

from the issue. In addition to cases of decay, arbitration sometimes ceases to exist, and the continuation of this is subject to

another, and sometimes it is not possible from the beginning of the arbitration in certain matters. All of these matters will

be scrutinized here.

MA in General Linguistics

Abstract

Presupposition is one of the topics in semantic study and Pragmatics. In this paper the researcher is more concerned about

the discussion presupposition in pragmatic studies, where presupposition is in one's mind about everything that exists in

the world. In this paper the researcher use descriptive research method, because all the data comes from animation and the

data is reviewed based on theory of presuppositions. Presuppositions in Sing animation are taken from the conversations of

characters in the animation, and then analyzed by the theory proposed by Yule (1996) about the type Presuppositions to

find out what types are often used in Sing. Finally the researcher has found five types of presupposition which applied in

Sing animation, they are 12 existential (13%), 21 lexical (13%), 23 structural (24%), 15 factive (17%) and 18

counterfactual (20%). From this paper also, the researcher expect that this paper can be useful both in learning as an

additional science in learning pragmatics, especially presupposition.

In this paper, we intend to study the foreign policy Discourse of the eleventh government of Islamic Republic of Iran in

the perspective Ernesto Laclau and Chantal Mouffe. The main question of this research is that the foreign policy Discourse

of the 11th government of Iran can be explained and examined with the previous governments discourses? It seems that

Iran's government has been seeking to present a new presentation of foreign policy discourse which would further promote

the national interests of the country .As a result, the eleventh government has tried to focus its slogans in the international

arena on the concepts of "constructive engagement with the world" and "national dignity" as the preferred sign in its

foreign policy discourse, a new subject with the motto " Moderation and moderation "in order to achieve the goals of the

Islamic Republic of Iran at the international level, and, by incorporating the new concepts into consideration, seek a new

identity in the international arena. The purpose of this article is to explain and analyze the foreign policy discourse of the

eleventh government at the international level.

Abstract

In recent years, intense pulsed light, called IPL technology, is used by physicians to perform various skin treatments. This

technology uses a general range of 550-1200 nm spectral light sources. Usually, to filter lower frequencies and limit the

optical spectrum, different high-pass filters are used to place the structure and specific chromosomes. In IPL, excited light

passes through a optic filter with a certain wavelength, depending on the wavelength of the light to be used in different

therapies. In this paper, manufacture of a high-pass filter is intended at a wavelength of 580 nm.The BK7 substrate was

considered and the TiO2 and SiO2 materials were used for the desired filter layer. This coating was carried out by the

EDDY coating device in a thermal evaporation method, in the laboratory of Photonics and Quantum Technologies

Research School. Finally, with spectroscopy of made sample, a very good match with the prototype spectrum was

observed.

Abstract

Effective management in construction projects is highly associated with establishment of coordination in an arranged flow

of material, transportation, money and human resource. Supply chain management (SCM) which includes movement and

storage of raw materials, work in-process inventory, finished goods and relations between them from point of origin to

point of consumption, is a strategic and effective tool for increasing efficiency of construction industry. The purpose of this

study is to design a supply chain network which consists of evaluation and choosing of suppliers especially in construction

industry. Thus by analyzing previous studies in construction industry and other fundamental industries, a supplier selection

model based on integration of Geographic Information System (GIS) and Fuzzy Set Theory is presented. In proposed

framework, first supplier selection criteria and their weights are determined. Then score of suppliers associated with factors

and rank of vendors are specified. Eventually, the proposed model is employed for a real construction project to

demonstrate application. This model interacts with considerable share of human judgment in supplier selection process and

imprecision of most of data in mentioned area very well.

Abstract

This study explores social identity of people in Nadine Gordimer's (1923-2014) July's People (1981)based on postcolonial

theories of Homi Bhabha (born 1949) and Edward Said (1935-2003). Concepts such as hybridity, displacement, otherness,

ethnocentrism and negotiation are explored, using the aforementioned theorists. July’s People is set in South Africa during

Apartheid era when the regime employed racial segregation. The blacks were considered as subhuman and inferior and

these discriminations and othering of the blacks resulted in their poverty. The rising of the blacks and their riot challenged

the regime for its treatment of the blacks. This causes displacement for the Smales who run away from their home and go to

the village of their servant, July and changes nearly every aspect of life for them. Hybrid and ambivalent identity is another

issue explored here. Hybridity is traced in the lifestyle and language of people, a combination of their language and

English. There is also colonial negotiation between July and the Smales. It was somehow difficult for July to grasp the new

conditions. The novel depicts the whites in a weaker position as the blacks take control of many cities and the whites are

subject to bias, discrimination and displacement by the black fighters.

Keywords: ambivalence, colonial negotiation, hybridity, otherness, post colonialism.

Abstract

This descriptive study examines the figurative language and its characteristics and specifications in Farsi and English as

corpus study in form of a contrastive analysis on metonymy in English versus Farsi based on semantics. To compare and

analyze the metonymies found in English and Persian corpora, two models are employed which have a lot in common.

One model is by Safavi (2008) and the other belongs to I. Saeed (2008).These two models were originally introduced by


21

Lakoff and Johnson (1978).Based on these models. The researchers adopted a modified version in which 25 types of

metonymy were identified to be applied to English and Persian instances of metonymy. According to this modified

version, an attempt was made to classify each instance in both languages based on this model in this study. As a result, 215

metonymic expressions were identified from two books and their authentic translations in Farsi. Findings showed that out

of 215 metonymic cases 172 of them were metonymic in Farsi while 99 of them were metonymic in English. Only 23

cases were matched and 7 matched metonymies were found as a proposed model for Persian learners of English.

Operational budgeting is a kind of planning, budgeting and evaluating system which emphasizes on relationship between

spent budget and expected results. In the frame of operational budgeting several official departments are responsible

responsiveness based on determined standards as operational parameters and managers are operationally more freedom to

determine the best method of achieving results. One property which provides field of conducting operational budgeting is

applying accrual base in accounting. This research aims to study the relationship between accrual accounting and

operational budgeting and improving responsibility of responsiveness. Results of conducted study show that compliance

and performance of operational budgeting in governmental systemsneed applying accrual accounting in order to determine

Abstract

This study was aimed to assess the effects of the chemical composition of the reinforcement nanoparticles on the

microhardness values of the Ni-Co alloy matrix nanocomposite coatings electrodeposited using DC current. XRD analysis

and Vickers microhardness tester were employed in order to evaluate the grain size and microhardness values of the

nanocomposite coatings respectively. Obtained results demonstrated that the grain size of the coatings deeply affected by

the both nanoparticles. However, the incorporation of the Si3N4 nanoparticles found to greatly reduce the grain size. The

microhardness value of the Ni-Co-Si3N4 nanocomposite coatings is greater due to the more refined microstructure.

Abstract

To use of CMOS technology, as well as the replacement of new materials in the devices, we need to increase the

functionality of the device. Using high-dielectric insulation materials in double gate SOI transistors can overcome

problems such as power dissipation and leakage. In this study, we investigated various insulation materials as oxide under

the gate in DGSOI transistors with a length of 20 nm. We concluded that HfO2 is a suitable option for DGSOI transistors

with a length of 20 nm due to higher cross-conductivity and lowering subthreshold swings and increasing the threshold

voltage . Also, in this research, a special type of device with dual material gate is considered, which in the term is referred

to as Disparate Dual Material Double Gate Junctionless SOIMOSFET (DDMDGJLSOIMOS). This particular type of

transistor improves the transmission of carrier, transients, and short channel effects. The results have been studied using

the Silvaco-Tcad two-dimensional simulator.

A Psychological Study of Orwell’s Nineteen Eighty-Four

through Jungian Personal and Collective Unconscious

Hamed Jamalpour

Ph.D student of English ,sub major Psychoanalysis at Saint Rose College, NY.USA

Abstract

This study aims to read George Orwell's master piece Nineteen Eighty Four (1984) with the help of Jungian theories. In

1984 Orwell creates a society of rebellious characters, cities in ruin and an oppressive, totalitarian government lead by Big

Brother. It is a world in which ignorance is bliss. The writer tries to examine the psychological behavior of each character

in the novel. Archetypes and myths or motifs which can be appeared in different genres and different times, but certainly


24

have the same psychological response and cultural function. Jung, the great, believed libido (psychic energy) to be more

psychic than sexual; also, he considered Freudian theories too negative because of the latter‘s emphasis on the neurotic

rather the healthy aspects of the psyche. Jung's primary contribution to this theory, was to develop the concept of personal

unconscious and asserted that beneath this is a primeval, collective unconscious shared in the psychic inheritance of all

members of the human family. Through the exact examination of the novel Nineteen Eighty Four we are going to see that

even for realities, governments can change reality by Double Thinking. In fact Double Thinking means changing the

reality to man- made reality, therefore this novel is a prominent example of literary works which casts off the usage of

psychological ways by governments to suppress the people. Within the story Orwell reflects the Jungian archetypes which

are dominant through the novel. For instance, as the novel opens, Winston (the main character) feels frustrated by the

oppression and rigid control of the Party which prohibits free thought, sex and any expression of individuality. So Winston

shows the Persona which Jung calls the social mask. Therefore the writer of this thesis tries to show the Jungian

approaches as used by Orwell in Nineteen Eighty-Four.

Geometrical, mechanical and electrical properties of carbon

nanocones

Ali Hasani

Department of Chemical Engineering, Ferdowsi University, Mashhad, Iran

Abstract

Geometrically, just as a sheet of paper with a wedge removed can be resealed to form a conical hat, a graphene sheet with

a wedge removed can be resealed, notionally, to form a cone or horn. The single-wall carbon nanocones form one class of

such conical structures. The pentagonal defects in carbon nanocones perturb the low-energy electronic structure both

locally and globally, defining both a local region of enhanced reactivity and a global geometric phase relation with

profound consequences for electron transport around the apex. The rapid variation in local sheet orientation around the

cone and the two-dimensional nature of the electronic states within imply that uniform laboratory fields can generate

highly nonuniform effective local fields for states in the cone.

Keywords: carbon nanocone, conical structure, electronic properties, geometric, mechanical.

Department of Chemical Engineering, Ferdowsi University, Mashhad, Iran

Abstract

Carbon Nanohorns (CNHs) are currently the subject of intensive research efforts, because their superior properties could

benefit many applications. This review provides an overview of Methods for CNHs Synthesis, using arc-discharge

methods. Mechanism of three main techniques were discussed; synthesis of CNHs by submerged arc, synthesis of CNHs

using the arc in water method with gas injection and Synthesis of CNHs by arc-discharge in air. CNHs with different

morphologies were generated by direct current arc-discharge between pure graphite rods in different atmospheres. Here we

show that three simple techniques that do not require relatively expensive laser and vacuum equipment provides an

economical alternative for the synthesis of CNHs.

Abstract

The existence of huge oil reserves in the Gulf region has made the region a major exporter of oil. Regarding the existence

of numerous countries with different policies and orientations in the Persian Gulf, various programs against oil exports

have caused other countries of harm. In recent years, among the three major oil producing countries in the region, Qatar,

Saudi Arabia and Iran, respectively, the first two countries have the largest oil exports to Japan and Iran to Sri Lanka. This

difference in stance requires further discussion, which can be seen in many of the reasons for reviewing strategic oil flows

in the region. This article, using the descriptive-analytical approach, tries to analyze the relations of their expression,

taking into account the geopolitical position of these countries.

Abstract

The electronic document management and electronic information sending and receiving make up the large part of today's

activities in the world. The use of computer-based information is significantly growing throughout the world. The digital

signature is one of the technologies which have increased the confidence. This encryption-based technique has recognized

the electronic information, so that the document creator's identity and his information comprehensiveness can be reviewed

and controlled; and the traditional methods of physical mark by seal or signature (for business and legal purposes) are

unusable due to the non-physical structure (data carrier). We haveproposeda digital signature scheme based on valid RSA

algorithm. RSA algorithm is a public key encryption system which provides both encryption and digital signature services.

Signature scheme based on valid RSA algorithm. RSA algorithm is a public key encryption system which provides both

encryption and digital signature services. This proposal scheme has the features namely the message confidentiality,

reliability, validity and integrity, incontrovertibility, and authentication. In this scheme, both encryption and

authentication are performed without sharing the private keys. Each person performs desired operation through his private

key or the opposite party's public key. Anyone can send an encrypted message or review a signed message. However, only

the private key holder can decrypt or sign a message. Due to the effectiveness of this scheme in terms of running speed

and duration and the existence of security parameters, it can be used on a variety of security systems such as smart cards,

Web server, banking systems, and so on.

A DFT study of titanium interstitial in rutile TiO2

Mohammadreza Elahifard Chemical Engineering Department, Faculty of Engineering, Ardakan University

Abstract

The formation energies of the titanium interstitial in rutile TiO2 was calculated by the Hubbard-U approximation in the

projector-augmented wave density functional theory code, ABINIT. The Ti interstitial generates the defect states in the

gap. These are unpaired electrons lie on the interstitial and the adjacent Ti 3d orbitals. By applying a sufficiently value for

the Hubbard-U parameter of the Ti 3d states, the excess electrons localize spatially at the Ti sites. We found the inserted Ti

atom pushes away the adjacent O atoms, forming a longer bond length at the octrahedral site.

DFT study on electronic properties of zinc oxide


Abstract

First-principles calculations are performed to study the electronic properties of zinc oxide (ZnO) in wurtzite phase using r-

PBE GGA approach as realized in ABINIT code. Our analysis after relaxation shows that the ZnO has a hexagonal

wurtzite structure with lattice parameters, a= 3.24 and c =5.20 A °. Our results for structural parameters with GGA-r-PBE

are closer to experiment as compared with other forms of GGA. Also numerical values for band gap with GGA are in good

agreement with previous GGAs and LDA calculations, however are underestimated to the experiment measurements. The

electronic band structure of hexagonal ZnO was calculated to determine the energy band gap of ZnO, which was

determined to be 1.75 eV. Analysis of our computed band structure reveals that ZnO in wurtzite phase is a direct band gap.

Abstract

In this work, the density functional theory method has been employed to investigate the adsorption of CO2 molecules on

(0001) surfaces of ZnO. A complete understanding of the carbon dioxide (CO2) interaction with zinc oxide (ZnO) is a

basis for the development of new ZnO-containing materials for catalytic of CO2 into useful chemicals such as methanol. In

particular, it was found that the calculated equilibrium structure and inter-nuclear distances are in agreement with previous

work. Chemical adsorption of CO2 was studied at (0001) surface, with bidentate and tridentate species. Heat of adsorption


29

for the bidentate and tridentate species on oxygen terminated (0001) surface was calculated to be 390 and 360 kJ.mol−1

respectively using PBE functional which has a little different with previous result. This difference is partially due to

exchange correlation functional and the number of layers used, since there is no significant difference of our structure in

relation to the reported data.

Abstract

Enhanced oil recovery is referred to a process in which oil is recovered by energy or materials outside the reservoir and

conventional methods are not used anymore. One of the important issues in reservoir management is taking some

measurements to protect the reservoir, increasing the production efficiency and keeping it a good level over the time.

Indeed, an enhanced oil recovery process cannot be used for different types of crude oil and we should use a set of various

methods. One of the methods is microbial enhanced oil recovery method. In this method, microbes or microbial products

are used for enhanced oil recovery process and it is called MEOR. The most important difference of microbial method in

comparison to other enhanced oil recovery methods is using a living creature as the most important factor of this process

and this causes some limitations in using this method. To do this, we should find a microbe in conformity to the

temperature, pressure, water salinity, sulfur and other harmful compound in the reservoir and besides the evaluation of its

performance mechanism in the reservoir; the conditions are provided for its survival. The present study attempts to have a

comprehensive view to different dimensions and introduction of MEOR method.

Optimize Solar Chimney Power Plant by integrating with Solar

Power Plant

Aziz Hoseinpoor

Abstract

The solar chimney power plant is a system that increases the air temperature (air molecules) by using solar heat and creates

air flow. Using air density, air flow can be controlled and placed on a specific path. Ironically, this movement of the air

causes wind turbines to rotate. In front of the chimneys of the sun, there are solar cells made of dark-colored silicon,

preferably with an unreflected surface, and stimulated by light to the surface and release the electron and generate

electricity. It is noteworthy about solar cells that use only sunlight, and the heat of the sun and the environment reduces the

efficiency of solar cells, and it is imperative to always cool solar cells, which is part of the maintenance of solar power

maintenance. In this new system, using two power plants and integrating them together, we use both the production of two

power plants, and also the flow of generated air can be aligned that both cools the solar cells and rotates Turbine is a solar

chimney. As a result, a power plant with a lower volume of power can receive two power plants and more than two power

plants.

Abstract

Recent advances have given rise to the popularity and success of cloud computing. However, when outsourcing the data

and business application to a third party causes the security and privacy issues to become a critical concern. Throughout

the study at hand, the authors obtain a common goal to provide a comprehensive review of the existing security and

privacy issues in cloud environments. We have identified five most representative security and privacy attributes (i.e.,

confidentiality, integrity, availability, accountability, and privacy-preservability). Beginning with these attributes, we

present the relationships among them, the vulnerabilities that may be exploited by attackers, the threat models, as well as

existing defense strategies in a cloud scenario. Cloud computing has emerged as a platform that grants users with direct yet


31

shared access to remote computing resources and services. Cloud must provide services to many users at the same time;

the scheduling strategy should be developed for multiple tasks. In cloud computing processing is done on remote computer

hence there are more chances of errors, due to the undetermined latency and lose control over computing node. Hence

remote computers should be highly reliable. This is reason why a cloud computing infrastructure should be fault tolerant as

well scheduling properly to performing tasks.

Abstract

The prediction of crack growth and fatigue in a composite laminate are affected by the unique and complex methods in

which the cracks can grow in laminate, and should be considered during design. With the knowledge of the factors

contributing to the vibration phenomenon, one can expect the optimal design of the parts. In this research, the natural

frequency for composite materials reinforced by short fibers and long fibers with the effect of crack orientation in the

middle crack location on the plate, for different aspect ratios of the fixed-plate type with simple supported conditions in all

edges using artificial neural networks has been studied. Volume fraction of composite plate sample from 30% fibers and

an error propagation law and a feed forward model are used in multi-layer perceptron artificial neural network. In this

research, using artificial neural networks, the crack angle and the aspect ratio of the plate as a network input are considered

and in order to achieve optimal model and optimal output, which is the natural frequency of the composite plate, despite

the crack at different angles, The amount of different Root Mean Square Error (RMSE), Mean Absolute Percentage Error

(MAPE), Mean Absolute Error (MAE) and Coefficient of Correlation (R²) for all models are calculated as one and two

layers, and two models with structures 2-4-15-1 and 2-15-1, respectively, for the geometric dimensions of the sample plate


32

with short fibers and long fibers, were selected as optimal models. In order to verify the validity of the results obtained in

this research, the comparison between the artificial neural network results with the experimental results obtained from the

time of load variations and the measurement of the natural frequency of the plate was performed and the results were in

good agreement and showed that the trained network can well, predict the effect of the oblique crack on the natural

frequency of the composite plate. At the end, the effect of the crack angle, the aspect ratio and plate geometry on the

natural frequency of the composite plate were evaluated.

A dedicated private-shared cache design for scalable

multiprocessors

Sajad Mosaybi Department of Electrical, University of Science and Industry, Tehran, Iran, [email protected]

Abstract

Today, given the importance of speed in computing and data processing, all the attention is given to creating a way to speed

up the modern computers. With the advancement and development of technology, the computer architecture has come to be

multi-core. In multi-core computers, if a shared cache is used, it generates network traffic and overhead, which in turn

reduces the efficiency of the overhead. In this paper, two distinct caches are proposed for two separate workings. One is the

use of a dedicated and dedicated cache of a completely separate shared cache, which will open the space and reduce the

latency and invalidity. Information in the shared cache is shared uniformly by the cores, and the dedicated cache is separate

from each other in terms of information, resulting in the use of this method to speed up. On the other hand, this method

requires a coherent mechanism to specify the nature of the data, and eliminates the lag and cache problems.

1. Islamic Azad University, Arsanjan Branch, Department of Mechanical Engineering, Arsanjan, Iran

Abstract In this study, the experimental study of the effect of iron oxide (Fe2O3)-water stabilized nanofluid on heat transfer in the thermal input

region of a horizontal tube was investigated. Also, some physical properties of nanofluid iron-water oxide were measured

experimentally and the effects of volumetric fractions of nanoparticles (0 ≤ φ ≤1) and temperature (25 ℃ ≤ T ≤45 ℃) were analyzed for

these properties. Experimental results show that the heat transfer coefficient of nanofluidic iron-water oxide increases compared to pure

water, and this increase can not be predicted by the Shah equation. For example, the nanosilver displacement heat transfer coefficient

with a one percent volumetric concentration of nanoparticles is more than 61% higher than pure water. Also, a significant decrease in

the heat transfer of the nanofluid of iron-water oxide in the 33.4×10-4 ≦Ha ≦136.6 ×10-4 (except Ha=36.3×10-4 was observed.

Abstract

Crack is among the most important causes of structural failures. As such, it is of paramount importance to detect crack

creation as soon as possible and at minimum cost. The presence of crack in a structure serves as a factor which modifies

structural characteristics of flexible object and affects its vibratory response. Therefore, the use of vibration data as a

non-destructive, low-cost, and fast method can be applied for the detection of crack position. Natural frequencies and

modal shapes of structure are sensitive to changes in stiffness and mass matrixes of the structure. Therefore, one can

determine intensity and location of defects by measuring the changes in dynamic properties of the structure. Even though

the sole presence of crack in structure can be relatively easily detected using the changes in natural frequency, but this is

not the case when it comes to the crack location. In the present paper, a method based on application of harmonic force


35

(forced harmonic vibration) is adopted for the detection of vibratory parameters and detect the defect location in

continuous systems such as beams. Accordingly, considering the necessity of analyzing and implementing the proposed

method, numerical simulations were conducted using MATLAB Software to characterize vibratory parameters (e.g.

stiffness and damping) of discrete systems, and the results were then investigated. The results indicated that, applying the

mentioned method, cracks can be nonlinearly modeled in beams, with their locations explored. Moreover, using stiffness

matrix of the cracked element, the crack location within the beam was detected and its depth was calculated. The

mentioned approach demonstrated efficiency of this algorithm in detecting different modes of damage.

Abstract

Owing to the importance of experimentation and measurements in natural science and engineering disciplines,

construction of mathematical models is an integrated part of the research performed on characterization of elastic systems.

Since the use of full-size models would incur large costs and took much time, different system identification methods have

been presented for the purpose of modifying software models to replace full-size models. System identification methods

can be used to determine properties of a software model in such a way that it simulates the behavior exhibited by the

corresponding real model. In the present paper, a method is developed for filtering experimental data; it is then used to

identify vibratory parameters and detect defect location in continuous systems such as beams. Accordingly, considering

the necessity of analyzing and implementing the proposed method, numerical simulations were conducted using MATLAB

Software to characterize vibratory parameters (e.g. stiffness and damping) of discrete systems, and the results were then

investigated. Applying the afore-mentioned method, cracks could be nonlinearly modeled in beams at high accuracy.

Moreover, using stiffness matrix of the cracked element, the crack location and depth within the beam were accurately

computed, indicating efficiency of this algorithm in detecting different modes of damage. In this paper, considering

practical limitations such as measurements in short time intervals, a method based on the application of harmonic force

(forced harmonic vibration) was presented for detecting vibratory parameters and locate defects within continuous systems

such as beams.

Abstract

Thr Pressure vessel are one of the most used parts in the industry and It is said Enclosures closed to be used to keep the

fluids pressurized above the Environmental pressure. These vessells are designed spherical or cylindrical and have a lot of

applications in the industry. The most common types of these vessells are cylindrical with two elliptical caps. These types

of vessells according to the type of operational need or installation location can be horizontally or vertically. For safe

design of tubes and Pressure vessel with Surface and peripheral cracks, Taking into account the conditions under

continuous loading, Usually considering the growth of fatigue cracks seems essential. In this paper, j integral values are

calculated using the finite element method in abaqus software for semi-elliptical cracks that have been created in the stress

concentration of pressure vessels is obtained. The results indicate that the integral value of j is constant amount and

independent of the path.That is, its value in a specific node of the crack front and on the different contours of course,

except the first contour, which is an exception, almost identical. On the other hand, since the J integral has the nature of

energy, Therefore, the negative is not the physical concept and the negative values are related to the integration of it.

The experimental study of the effect of zirconium oxide

nanoparticles on the conduction heat transfer coefficient of

water and ethylene glycol

Farzad Jabbari1, Hamid Reza Ghezavati

1- Islamic Azad University, Arsanjan Branch, Department of Mechanical Engineering, Arsanjan, Iran

Abstract In this study, the effect of zirconium oxide nanoparticles on the thermal conductivity of water / ethylene glycol was

investigated in vitro. Therefore, zirconium oxide nanoparticles (ZrO2) based on water and ethylene glycol mixtures (with a

ratio of 20/80, 40/60 and 50/50) were used. Ultrasonic waves were also used to stabilize nanoparticles in the base fluid.

Experimental results show that the ethylene glycol conduction heat transfer coefficient is less than pure water. With

increasing temperature, the ethylene glycol conduction heat transfer coefficient is increasing. By adding ethylene glycol to

pure water, the conduction heat transfer coefficient decreases relative to pure water. Also, with increasing temperature, the

conduction heat transfer coefficient of the water mixture and ethylene glycol increased. The addition of zirconium oxide

nanoparticles in a different volume fraction to the base fluid (water mix and ethylene glycol) has an increasing trend in the


37

conduction heat transfer coefficient. For example, at 80 °C, zirconium oxide nanoparticles with a concentration of 2% vol

as compared to the addition of zirconium oxide nanoparticles with a concentration of 0.5% v/v increased 16.26% and

compared to the base fluid (water and ethylene glycol with 50/50 ratio) We have a 38.5% increase in the conduction heat

transfer coefficient.

Abstract

In the old government, the government did not have civil responsibility, but it was gradually referred to this responsibility

among legal regimes. Nowadays, civil responsibility of the state is accepted as a principle, and personal responsibility,

responsibility for non-liability and liability arising from objects, and even the responsibility of the state towards the

exercise of the judiciary. Since the civil responsibility of the state, part of the public law, and more specifically, is a part of

civil rights of the public, and it is not solely devoted to private property, and the state as a public official in public law is

responsible for its actions. In this article, while addressing The pillars of the civil responsibility of the government for the

theory of this in the field of public law have been addressed and the status and attitude of our legal system (Iran) towards

civil responsibility of the state during the mentioned issues.

Abstract

Preterm dehivery is one of the most common problems that is considered as the most important cause of illness and

mortality in neonatal period and can be associated with the disorder of normal pregnancy. Preterm infants, are most at risk

of developing severe medical conditions that can affect the respiratory, gastrointestinal, immune, central nervous, auditory

and visual systems. Current methodologies to assess the process of labor, such as tocodynamometry or intrauterine


38

pressure catheters, fetal fibronectin, cervical length measurement and digital cervical examination, have several major

drawbacks. Uterine contractions are a result of the electrical activity within the myometrium and measurement of uterine

electromyography (EHG) has been shown to detect contractions as accurately as the currently used methods.The aim of

this paper is to evaluate nonlinear features and a combination of classifiers for Predicting preterm delivery. We used 76

electrohysterogram records from two groups according to the total length of gestation: 38 term delivery records (pregnancy

duration ≥37 weeks) and 38 pre-term delivery records (pregnancy duration ≤37 weeks). The extracted features were

classified by using three classification method including support vector machine, quadratic discriminant, k-nearest

Abstract

Tabari's History (313 AH) is one of the sources of historicist writing that has been taken into consideration by the later

historians; Some have come up with praise and expression in the history of Tabari, and others, like Ibn Khaldun and Ibn

Atir, have questioned the contents of Tabari's reports. Achieving truth and historical realities in such conditions is difficult,

but it is possible, provided that scientific criteria are met in the assessment of historical propositions. This article tries to

study the content pathology of Tabari's historical reports and finally concludes that; Incorrect reports and reports of the

Israelis in Tabari's history, such as Zabihhh know Ishaq by attributing speeches to the Prophet (PBUH), Hadiths of

materialism and materialism, having God, the narrations of determinism, narratives of the creation of "pen", The traditions

of the days of God's creation and comfort, and the errors of the prophets, such as the legend of David with Betheshebe, the

wife of Ourya Hitti who are definitely alien to the attention of the evidence and reasons, Providing historical data on the

Qur'an and authentic tradition, studying the narrations, utilizing the wisdom and other sources, reveals the truth.

Abstract

Nowadays water consumption in many countries has reached to alarming level. So they should use an alternative for this

goal. Air-cool condensers and dry cooling towers are good substitutes for this action, but they have limitations. The most

important limitation is higher heat rejection temperature in warm seasons and it leads to higher condenser pressure which

produce backpressures at the condensing turbine’s exit especially during high speed wind. In this study an absorption

refrigeration cycle for heat rejection from condenser of Mofateh steam power plant is investigated. In this study, we use an

absorption chiller system with air cooled cooler instead of existing wet cooling system of Mofateh power plant. The heat

that power plant condenser is rejecting is handled by the evaporator of absorption chiller and lift up to a higher temperature

where the absorber and condenser of absorption chiller are handle it with air cooler heat exchangers. The Generator

(desorber) fed by the steam that extract from power plant itself. Therefore, there is no consume of water in power plant

condenser. The effect of main parameters such as generator and air cooler temperatures were studied and results presented

here. At the end, we used a real absorption chiller system to have a comparison. As results shows there is a stability in

turbine’s work and cycle efficiency while ambient air temperature changes.

Abstract

Some of the musical movements of the early 20th century made various experiences in discovering and producing new

sounds, so that electronic instruments as well as mechanical facilities of sound production are some of their achievements.

Although conservative composers did not approach to such experiences at first, but since the second half of the 20th

century, with the expansion of the thought of starting from sound to reach music, a new phenomenon called electronic

music was shaped and developed by some composers. The history of this music is entirely dependent on the development

of electronic technologies and has been transformed widely since the late 20th century with the spread of computer use. In

fact, computer with the simulation of electronic circuits as well as the programming capabilities, could better achieve the

goals of electronic music, to some extent that today laptop has become a kind of electronic portable instrument. The present

article considers the historical development of this music and introduces its prominent status in the future.

to return to them and to study the elements of that era. Treasures that over time they reached great damage and worse, they

see the damage caused by our negligence.Getting to the museum and the effects it is important that How to Run the root

pattern design and decorating objects and textiles in the Qajar period is very unique and yet unknown. This despite the fact

that unfortunately a large number of residents of the city of Tabriz even are not aware of the existence of the museum and

its treasure lies at the heart of it. The next goal of the study,is getting the outcomes of this research to enthusiasts and artists

who are in search of new information about the works lying silent and without source in the museums.

Abstract

Today, the use of distributed generation units in distribution systems has increased dramatically in many parts of the world

to improve the distribution system parameters. In the meantime, it is necessary to investigate possible problems and

problems in the distribution system due to the use and utilization of scattered resources.

Dispersal products (DGs) are small production tools that can be connected to any point in the power system. By optimally

utilizing these units, it can reduce system losses, improve the voltage profile, increase load capacity, and release thermal

feeds. Designing distribution systems in the presence of DG requires definition of various parameters such as best

execution technology, number and capacity of DG units, best location and type of network connection. The issue of

exploiting scattered resources is very important. Installing DG Units in non-optimal locations can lead to an increase in

system losses, an increase in costs, and thus have a counter-result to the desired result.

In this research, the main problem of optimal utilization of distributed generation and its effect on the distribution factors of

the distribution network. Another goal is to investigate the effect of the random behavior of loads on the distribution system


47

on improving the system's loading capacity by DG. This research shows that the optimal exploitation of distributed

generation generators can affect how well the system's voltage and loadability profile can be improved.

Abstract

Today, Cluster based routing protocols are the most useful schemes for extending Wireless Sensor Networks lifetime

through dividing the nodes into several clusters and electing of a local cluster head for aggregating/fusing of cluster nodes

data and transmitting a packet to Base Station. However, there are several energy efficient cluster-based methods in the

literature; most of them used the topological neighborhood or adjacency as main parameter to form the clusters. This paper

presents a new centralized adaptive Energy Based Clustering protocol through the application of Self-organizing map

neural network (called EBCS) which can cluster sensor nodes, based on multi parameters, energy level and coordinates of

sensor nodes. We applied some maximum energy nodes as weights of SOM map units, so that the nodes with higher

energy attract the nearest nodes with lower energy levels. Thus, a cluster may not necessarily contain adjacent nodes. The

new algorithm enables us to form energy-balanced clusters and distribute energy consumption equally. Then the number of

clusters will be optimized by means of FPAKM algorithm.Moreover, we proposed a new cost fuction to incorporate

different useful criteria for election of Cluster head nodes with energy efficiency. Simulation results for different scenes

and comparison of them with previous similar protocols (LEACH and LEA2C) prove that the new algorithm is able to

reduced latency and energy consumption.

Abstract

Silicate bioceramics have attracted too much attention as a new family of biomaterials in hard tissue regeneration

applications. Investigation have shown that novel bioceramics sush as Akermanite and wollastonite perform better than

Hydroxyapatite in repairing bone tissue and possess better mechanical and bioactivity properties. In general, Akermanite

and Akermanite composites have better osteogenic properties than Diopside, Merwinite and other calcium-magnesium

silicates from the Millite family. In this study, Akermanite and wallestonite based on Cao , Mgo , Sio2 that have recently

been known as bioactive bioceramics , were syntherized via a sol-gel approache and calcined in varions temperatures.

Phase analysis were investigated and characterized using XRD , SEM. The results of xrd confirm the formation of pure

merwinite and wollastonite with grain size of aboute 16.72 nm respectively. Regaeding all the obtained results , it can be

noticed that merwinite and wollastonite bioceramics having Ca , Mg , and Si can be used az new and promising

biomaterials in bone tissue repairing applications. Thse bioceramics have a wide range of aplications in the filds of tissue

engineering and repairing diseased tissues due to their unique properties like bio compatibility , bio degradability non

toxicity and their stability in body`s physiological environment.

Abstract

LaMnO3 perovskite was prepared by the sol-gel auto-combustion method, then supported on CeO2 as a support by

impregnation method and was tested in the process of catalytic NO reduction with CO. Structural characterization,

morphology and crystallite size was performed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The

XRD study analysis showed that the LaMnO3 compound crystallized in a perovskite hexagonal structure and CeO2

indexed to a cubic fluorite structured. The result of SEM indicated the well dispersion of the perovskite oxide on the


49

support. Conversion of both reactants NO and CO for LaMnO3/CeO2 is higher than LaMnO3, due to the higher dispersion

of LaMnO3 on the support. LaMnO3/CeO2 has more tendency to reduce CO and convert it to CO2 as a product.
