Abstract

Poovar is situated in the southern most region of Thiruvananthapuram district. As it is situated on

the seashore, lots of wasted fishes polluted this area. If these can be collected and converted into value

added products we can eradicate the pollution. The main objectives of this study are 1. To eradicate the

pollution problem of Poovar coastal region by the wasted fishes (Fish manure production). 2. To find out

whether the jelly fish found on the coastal region of Poovar can be used as an organic pesticide.3. To

motivate and give awareness to the students and public about the fish manure and jelly fish pesticide

made from wasted fishes and to make them interest in agriculture. This is an experimental based project.

Data was collected by survey and interview also. Time duration:11/07/2016 - 18/10/2016.

Experiment (1) Preperation of fish manure and efficiency test. Wasted fishes and fish wastes were

collected from the sea shore, dried under direct sunlight for 5 days and powdered well to make fish

manure. 9 flower pots of same size, soil, cow dung, seeds of pea plant, lady's finger, and spinash were

collected.The seeds were transferred into the following cultivation media as follows. 1. Ordinary soil -

Sample A (control) 2. Soil+cow dung (3:1) sample B, 3. Soil+ Fish manure (3:1) - sample C.The

germination rate and growth of plants were recorded. Experiment (2) Take 1kg jelly fish in a vessel and

add 1 l of water.Boil it till it come to 1/3. Allow it to cool. After that add 1l of water in 1l of pesticide

to dilute it. Spray the pesticide in pea plants and chilly plant which was affected by pests. Survey was

conducted in 100 houses with survey form. Interview was conducted with Professors of Vellayani

Agricultural College.

From the experiments conducted it was found that germination rate of seeds were high in sample

C.Plants in sample C kept the pace of a better growth and better health. Jelly fish pesticide removes the

pests in pea plant and chilly plant. People who participated in the survey cultivated vegetables like beans,

chilly, brinjal, spinach etc. 90% of the families are not using pesticides. 83% are not aware of organic

wastes.The fish manure tested in the agricultural college lab contains N- 8.9% , P2O5 - 6.5 %, K2O -

1.2%, Fe - 1235ppm, Mn - 290 ppm, Zn- 110ppm and Cu - 45ppm. There is no facility in Kerala to test the

jelly fish pesticide for finding the content which acts as pesticide. Conclusion : A very good bio

fertilizer can be made out of wasted fishes and and fish wastes. A very good bio pesticide can be

developed using jelly fish. Fishes contain many types of minerals and they are beneficial for plant growth.

If the wasted fishes are used properly, we can avoid pollution.

ABSTRACT

Energy is a very essential factor for the sustainable development.So conserving energy for the

future generation is our duty.Hence we decided to findout the major energy losses in our surroundings and

to find out methods to minimise the loss.Through our observation we found that in tea shops there are a

huge of enery due to the continuous use of fuels to boil water.

Objectives:

1)To understand the energy usage in boilers,using in the tea shops .2)To study the various types of

boilers and different fuels using in the project area. 3) To understand the importance of position of outlet

pipe of boiled water in the boilers.4)To find the energy loss through vapourisation when water is

continuously boiled in the boilers.5)To find methods to reduce energy loss through experiments.

Methodology:

1)Observation.2).Survey.3)Interview.4).Experiments. Out of 186 tea shops in our Panchayath we

take 56 tea shops for survey.We also conducted interviews and five simple experiments to find the energy

loss and to minimize the loss.

Workplan:Our project area was MaranalloorPanchayath and the study done in 3 months.

Analysis of Data and Results:

85.71% of the tea shops in our study area are using steel boilers and 96.42%are not utilising the

water in the boilers completely.Hence there are loss of water ,energy and fuel due to evaporation . From

our experiments we found that the water at the top of boilers are having greater temperature than that at the

bottom(6-7℃).Hence an additional pipe should be place at a two-third height of the boiler and an inlet pipe

should be connect at the bottom of the boiler to add cold water. Then we can save energy.If we add cold

water through the bottom of the boiler we can take the hot water through the pipe at the top at the same

time.Because the less dense hot water in the top of the boiler does not mix with the cold water at the

bottom.Hence we propose a structural change for the boiler with an additional outlet pipe at the top and the

inlet pipe at the bottom.Also we found that energy loss and fuel loss can be minimised by reducing the

quantity of water taken in the boiler .Energy loss per day due to evaporation can be minimised by 1282

kcal due to the structural change.More over at the off time (minimum sale of tea) if we cut off the LPG for

15 minutes,and boiling the water for 5 minutes instead of sim position,we can save 194 Kcal of energy

and 0.0162kg Lpg fuel per day.

Conclusion:

If we reduce the quantity of water in the boiler (15l to 10l) we can minimise the energy and fuel

loss.The structural change and a systematic use of boilers can save large amount of energy and fuel.


Future Plan:

To sensitize the teashops owners about the methods to minimise water loss, energy loss and

fuel loss a notice is prepared and circulated in the teashops.An awareness classis also taken for them.

ABSTRACT

Agriculture is the most significant factor for existence. The process of leaves being used as manure

existed from ancient time itself. This project focuses on how the allelo chemicals of leaves influence the

sprouting of seeds and the types of leaf loppings promotes and negatively influences growth of the plants

Our Objectives are,

1. Which are the leaf lopings helps and adversely effects the sprouting of vegetable seeds.

2. Which are the leaf lopings helps and which are adversely effects the growth of the plants.

3. How the allelo Chemicals affects the growth of the plants.

On observing our home and school premises we noticed the abundance of a plant named

wedalia we saw that other plants don’t grow near it. On feeling the urge to know more about the identical

plants, we approached our biology teacher shri.saseendran master and DR.K.M Sreekumar associate

Professor in Entomology department of Kerala Agricultural University Padnekkad. We had interviewed

with about 25 farmers from ward numbers 5, 18, and 19 of Kanhangad Municipality. Most of them use leaf

lopping (tholu) and we studied about the prominent leave that they utilize. Out of them we selected 5 leaf

various for our experiments.

We divided our experiments into 2 phases. The first one concentrated on the variety of leaves that

promoted or negatively influenced seed sprouting and plant growth. For this we prepared 54 packets in

news print paper containing the seeds of Amaranthus, Ladies finger and peas. Afterwards we collected

100g/1ltr of grinded leaf powder of Glyricidea,Teak, PongaminaGlabra, Wedalia, and MacarangaPeltata. It

was socked and the solution was preserved for 3 days. Then each solution was poured in the packets of

Amarandus, Ladies finger and peas. Further we observed 3 packets of each separately pouring water in

them.

The second stage focused on the effect of leaf loppings on the growth of vegetables. The same

leaves and seeds used for first stage of experiment were utilized. After sprouting the seeds of Amaranthus,

ladies finger and peas the solution of Glyricidea,Wedalia,PongamiaGlabraMacarangaPeltata (T1,T2

,T3)were poured into them. The experiment was done with water and an analysis of comparison was noted.

The first stage of experiments taught us that the most effective leave for seed sprouting are that of

Wedalia and Teak. Besides it was seen that the leaves of MacarangaPeltata and Glyricidea are

detrimental to sprouting. Knowing about the influence of leaf lopping in the growth of plants we

understood that the most favorable one is Glyiricidea T1 solution. The growth rate had been better than

that of control. The rate of growth of solution of PongaminaGlabra and Teak was identical to that of

control. But growth rate was less in the leaves of Wedalia and MacarangaPeltata.


The process of study included interview, experiments and observations. We measured the length

and width of leaves and length of root and stem and the fresh weight of the vegetable plants. Thus we

arrived at the following conclusion

i. Glyricedea,MacarangaPeltata adversely affect sprouting of seeds

ii. Glyricidea, Teak and PongaminaGlabra promotes the growth of the root, stem and leaf of plants

iii. Wedalia and MacarangaPeltata lowers the growth of root stem and leaves

iv. Wedalia and Teak are most congenial for seed-sprouting

v. Though Wedalia helps the sprouting of leaves retards later

vi. Glyricidea is the most fruitful for the growth of plants

The study product was taken to farmers and administrators. Our suggestions are,

Loppings of Teak and Glyricidea are more effective loppings of teak and Glyricidea are most effective bio

fertilizers for plants

To prevent the effect of allele chemicals in WedaliaMacarangaPeltata, lime should be applied in the soil

Cow dung is to be applied

Ash becomes hydroxide with the water and promotes plant growth

Farmers have to be given awareness about bio fertilizers

Glyricidea and teak should be given prominence in afforestation

The project appears significant in the field of organic farming for propagation of it and

informative notices were distributed among kudumbashree,Classes were given,Copies were handed over to

K Raju and V.S Sunilkumar Ministers for forest and agriculture respectively, Shri .V VRameshan the

Chairman of the Kanhangad Municipality and Shri Unnikrishnan the 19th ward Councilor

ABSTRACT

Balancing of energy production and environmental protection is one of the greatest challenge

modern era human beings are facing. Majority of the energy sources that are being used today cause high

threats to the environment and will deplete in the near future. Only a small percentage of world’s energy

need is sourced from sustainable energy sources (wind, solar, sea tides).

In this context, the present work was an attempt to boost the idea of microbial fuel cells (MFC) and

to check whether the bacteria isolated from dung of wild animals could produce more electricity than other

bacteria. Main objectives of the study were to find out a potential bacterium for energy production,

compare the energy production of bacteria isolated from two sources (dung of Gaur/Indian bison and

domesticated breed of cow) and to find out a media that support high energy production.

The dung of wild animal (Indian bison) was selected for the study as it lives in natural

environmental conditions and may harbor multitude of microorganisms than domesticated breeds. Using

appropriate methods (pyrogallol method) the anaerobic bacteria was isolated and inoculated into the

medium (thioglycollate and nutrient broath). A microbial fuel cell was setup using indigenous methods and

was connected to a multimeter to measure the electricity production in single system and series connection

(5 MFC).Similarly another bacterium was isolated from the dung of domesticated cow and compared the

energy production. Supporting ability of the medium was also accessed.

The results showed that energy production from bacteria isolated from gaur dung was higher

(0.42V), compared to the domesticated one (0.2V).while connecting in series, the electricity production

was 1.98v for bacteria from Gaur dung and 1.04V for bacteria from domesticated cow dung. Regarding the

medium that support maximum energy production, it was found that thioglycollate medium showed the

highest voltage both in single (0.57V) and series (3.3V) connection. This study also pointed out that the

bacteria isolated from the Gaur dung has higher potential in the production of electricity compared to other

bacteria. Series connection with 5MFC produced 3.3V which is a better voltage. Thus we found that the

bacteria present in the dung of wild animals can produce better electricity.

The study is promising in the search of sustainable energy sources and would be taken upon for

further improvements. MFC could be considered as a bio-battery where a highest quantity of ‘clean

electricity’ could be produced from lowest space and byproduct developed out of MFC could be used as a

bio-fertilizer. More studies and support would be needed in this

dimension._____________________________________________________________

Abstract

We have conducted a survey in to the importance of medicinal plants courtesy Mathrubhumi seed

club. As we went about exploring certain this survey related activities we came across a fact that if

moringa plants were cultivated along the brim of open wells they would shed their dry nuts during

summer right in to the waters of the wells and this desiccated seeds would purify waters there is quite

naturally and unsparingly .This serendipitous privy in to the legacy water purification method triggered an

abiding interest in us which set us on a path of exploring various water purification methods of the yore

specific to the said Panchayath area.

Water use model has a direct effect on human health. To stake the obvious use of polluted water

leads to catch of umpteen water –borne diseases .Such diseases that struck the country side of the

Palakkad district during the months of June and July exemplifies this mater. The age is marked by rampant

contamination of potable and irrigation water as a matter of course and hence this study about water

purification practices assumes unassailable significance. The unraveling of scientific truths embedded in

each vintage water purification strategy is a dire need of the hour which any conscientious and socially

committed knowledge community can’t afford to turn its back on .

Seek out traditional plant using water purification methods, conduct of awareness promotion

programmes regarding the imperative of the use of water purification, transfer of knowledge about certain

esoteric water decontamination practices to the public domain, conserve plant varities which possess

water purification engendering properties are the major areas that the proposed study should be at pains to

delve deeply in to. An active plan from July 6 and culminating on 25th October was put in place. Survey,

experiments, interviews, data gathering etc were the tools used in the study. A questionnaire containing 20

queries was distributed among 100 people most of whom were above 50 years of age. This investigative

exercise yielded 10 different plants which boast water depolluting capabilities. Our study then zeroed in on

a selected few of those 10 items to undertake more serious probe into.

Passing muddy water through a sieve of Coriander leaves, putting ground Tarmarind, Jackfruit,

Thettambaral, Moringa nuts in to impure water were the two major experiments that we conducted. Using

PHpaper, soap solutions, passing light rays, using bacta slides etc, we compared the curtailment of PH,

hardness turbidity and coliforms of water. From this experiments we could know that Coriander plants,

Jack fruit nuts,

Moringa nuts are more fit for water purification and so we repeated the process once again and sent the so

purified water sample to water testing lab. In the lab report we found that PH and hardness elements in the

tested purified water samples almost remain unchanged at the same time scale down of turbidity, TDS,

fluoride, alkalinity, acidity, Coliform levels were detected in the sample purified with Moringa nuts.

Cationic protein in Moringa nuts was responsible for the escalation of the purity level of the water

sample was understood from the interviews taken and for the sake of further assurance of protein presence

Biuret test, xanthoproteic test were conducted.

All know for sure that impure water is causative of ailments galore. But people are in the dark

about traditional water depollution practices. When we put in to perspective the above mentioned fold

wisdom of water purification we could understand that Moringa nut method is more cheap and ecofriendly.

Successful Moringa cropping and this method is possible in terrains as diverse as villages, urban centers

and even within the enclosed spaces of industrial establishments of all size. It is a multi utility proposition

in that Moringa Provides edible substance of high nutritious value, purifies water and it saves the tiller and

the ecology. Coriander plants are very capable of absorbing fluoride is another land mark finding.

Knowledge about the medicinal properties of various plants are unknown to the humanity, over use of

water and inordinate spike in water pollution inch towards a breaking point seemingly in an irrevocable

manner. Water borne diseases are given a free hand to take their perilous toll with impunity. Traditional

water decontamination practices get a quiet burial. Use of excessive chemical water depollutant turns least

worrisome are the woeful problems that we confront at the closure of our laborious study.

Control water over use, dodge pollution causing circumstances, raise awareness level about the

imperative water purification drives scout for period water purification strategies, grow depolluting plant

varieties are the solutions to this current hazardous scenario.

As a follow up to the study a class was conducted in which delegates from various school took part. The

need for understanding various water purification programmes and rooting for traditional know-how to

realize it was held forth at length in the class. An awareness class was also conducted in

VanamalikaKudumbasree unit. Press clippings were garnered and exhibited in the science club to make

sense of the outbreak of water- borne diseases endemic to certain parts of the district of Palakkad. A

working model was created using Moringa nuts for water impurities removal. Moringa, Jack fruit and

Tarmarind Saplings were planted in domestic plots and elsewhere in our neighbourhood.

Follow up after district meet

We requested to the panchayath president to distribute Moringa and Jack fruit plant all over

Kannambrapanchayath and to plant moringa trees near water resources. We distributed moringaplants in

our school.

Follow up after State meet

There is a lot of complaints about Kadampadam water purification plant which is situated near our

school. So after state meet we planted moringatrees near this plant which in river bank Mangalam. This

work done in co-operation with KannambraPanchayth under the project “HarithaKeralam”, Sujalam-

Sulabham of Kerala Government.

ABSTRACT

Introduction:

In Our school polyester fabrics are adopted as uniforms.We select our project topic as the''

problems felt while using these uniforms in this warm climate”

Objectives:

i) polyester or cotton is suitable for sustainable development ii) how rural industry supports

sustainable development

Methodology:

Survey , Experiments , Interview , Resurvey , Field Trip , References

Survey Results:

Total No. of uniforms used in our locality (6 Schools) = 22 ,

Total no of students passed out in each year from our locality = 2000(nearly)

Usage of Worn out Uniforms : 21% _ Burns , 64% - Dumped in Shelves, 2% – Reuse

10% – Buries, 1% – Recycling

Health issues = 17%

Period of usage of dress as school uniforms: for 1 Year –5% , for 2 Year –57% , for 3Year-38%

Even though polyester fabrics are supposed to use for long term purposes, school uniforms are maximum

used only for three years and nearly 2000 students completed their course in each year in our locality itself.

This causes huge waste of polyester fabrics.

Experiment:

i) Biodegradability Test: under same conditions, hand loom, cotton (from mill), ploy cotton and

polyester cloths having uniform measurements are dumped in soil. After 30 days we can found that the

weight loss of hand loom is very high.

ii)Burning Test : Burn different types of fabrics and found that cotton makes less pollution.

Handlooms are Compostable and more ecofriendly

Interview:

Interview with doctors ---prolonged use of polyester fabrics may cause itching, fungal infections,

skin diseases, kidney and liver damage, and even cancer....

Resurvey:

On the basis of interview, we conduct a resurvey. Out of 200, 52 were suffering from mild type of

fungal infection, itching, and skin diseases. Of these 52, 76.9% of them are girls with over coats

Less water absorbing capacity of fabrics ---- More chance to produce health problems. So we conduct an

experiment to check the water absorbing capacity of different types of fabrics.

Experiment:

Wicking Property of Fabrics: Different cloths with same measurement are dipped in water and

observe the rise of water level in these clothes in each five minutes. We can conclude that the wicking

property of cotton especially hand loom is very high when compared to polyester.

Field Visit :

Visited the working units of KHADI and HANTEX at Calicut .Hand loom cloths are more health

friendly, environmental friendly and human friendly---Moreover it is a job opportunity for the rural

women,especially destitute------gives development to rural villages---pave way to sustainable development

of KERALA . Also the advantages of hand looms are,

I) Except for dyeing, no chemicals are used while manufacturing.

ii) Breathing capacity of hand looms are very high.

Iii) Gives job opportunity to rural women.

Iiii) Hand loom industry is totally Eco-friendly

Conclusion;

i) Prolonged use of Polyester cloths makes health issues. So avoid polyester fabrics as uniforms.

ii) In each year lakhs of students are completing their courses in all over India and their worn out uniforms,

if not properly reused, should produce so many environmental issues

iii) Hand looms are health, eco and human friendly and supports sustainable development.

iiii)Hand loom industry gives sustainable development to our country.

Continuous Activity:

Instead of artificial dies how we can use natural dies. Quantify the hazardous chemical content of

the smoke and deterioration of the microbial flora of the soil while conducting our experiments.Can Study

the activity of Polyester degrading bacteria in the worn out uniforms.

Suggestions: In all over India, all educational institutions should adopt HAND LOOMS as

uniforms. Also Govt. should give 30% rebate to all uniform clothes. Of course, it is not a profitable

business. But , don't consider this as a mere deal between govt. and students , but an exchange of a great

MESSAGE.....”THE MESSAGE FOR SUSTAINABLE DEVELOPMENT”

ABSTRACT

Objectives

1) To understand the rate of paddy production and area under cultivation in Kozhikode district and

Kottavayal. 2) To find out total paddy production, total population in Kottavayal and their percapita

consumption of paddy, source of rice currently in use, distance of transport and carbon foot print of rice. 3)

To collect details about nutritional value, adulteration and processing of rice 4) role of mechanization and

water availability in the rate of production and also find out the crisis faced in the project area. 5) To know

about different varieties cultivated in Kottavayal and suggest proper varieties and methods of cultivation in

Kottavayal. 6) To understand the attitude of common people and students towards paddy cultivation.

Objective wise methodology

Interview (Agriculture Officer, Panchayath President, President Kottavayal paddy field collective, Food

safety Officer, Manager (Elements- Parallel organic market), Indian Agronomist Prof. K P Prabhakaran

Nair, Director seed farm, Statistical department Officer, traditional farmer, young farmer, Organic

farmers-Cheruvayal Raman, Illias Thrissur, SoorajWayanad)

Field study (JayakrishnanChathamangalam, BalakrishnanKizhakkedath)

Survey (100 houses in Kottavayal, 45 famers, 214 students)

Data collection(nutritional value of rice, mechanization in paddy field, traditional agriculture tools,

different types of seeds, storage, germination, sowing, stages of growth, reaping processing and marketing)

Experiment(germination of seed, find out adulteration in rice)

Observation (different stages of seed germination, presence of oil, colour and plastic contents)

Comparison (production of paddy in Kottavayal with other fields having similar climatic conditions and

geographical area , fund utilisation by PanangadPanchayath in agriculture and other developmental

projects, varieties of seeds)

Analysis (Land use, attitude of common people, challenges faced, use of polished and unpolished rice)

Result

Area of paddy field getting reduced year by year, remaining paddy field is not under cultivation.

Indifferent attitude of people and extensive field filling leads reduction of cultivating land. Improper

irrigation and absence of farmers’ collective leads to decrease in production.

Conclusion

Paddy field area grossly reduced, local production and local market are possible, proper irrigation

system and public attention are needed, farmers’ collective, preservation of traditional knowledge,

government policy measures are essential

Remedial measures

Permanent shutter system, concrete walls in both sides of the shutter, field bothies from VCB(vented

cross bar)at Kizhakkuvattathazham, local farmers’ collective, local processing, local market, selection of


high yielding paddy seed varieties suitable for Kottavayal, organizing effective farmer’s collective,

effective interventions from the part of the Local bodies. Ample importance should be given to agriculture

in school curriculum, economic scaffolding may be given to farmers and consumers for paddy market,

policy decision should be made to encourage agriculture and farmer friendly mobile apps for traditional

knowledge on paddy cultivation.

Follow up activity

It has been decided to cultivate paddy, open a center for local market with the cooperation of

alumni association, to conduct awareness classes, master plan has been prepared and released, mobile app

and Face book page have been created for easy access to traditional knowledge and memorandum

submitted to ministers, MLA, President District Panchayath concerned.

ABSTRACT

India is the second populated country in the world, where energy requirement in any form is very

important to the nation and use of all kind of energy must at its optimum. Go through kitchen, our

endeavour is highlight to conserve energy from our daily use of kitchen. Concave bottom vessels and

rippled bottomed vessels are more efficient to absorb heat compared to conventional vessels. Stove and

wood gas stove consumes less wood, time and more energy efficient compared to common hearth. Cooling

fins in computers can absorb more heat. So this same shape and principle is used in our new vessels. Metal

pot with ring inserted in inner bottom surface can increase convection current of water. Through various

experiments, we have proved that these stoves and vessels are more efficient. As a tribute to our mothers,

we made a small change in our ordinary hearth. We attached a blower with 9volt battery and connected to

hearth. Thus mothers do not have to blow the hearth any more.

farmers suggest them planting by moon phases – may reduce the problem. We are studying the subject by

making a hypothesis. Does planting and cutting during different lunar phases affect plants? We have done

surveys, interviews, observation and experimentation. We planted 60 peperomea plants separately in a

controlled system and everyday though a moon phase we took sections of two plants each, after adding 10

ml of fluorescent ink in the soil before 10 hours, using a mobile gear universal 68 x microscope macro

mobile camera lens with UV light we took photographs of hundreds of sections in all 28 days and found

that fluorescent ink spreads in the xylem tubes more during new moon and coming 3 days.

Then we took 50 sections from tender stems of Manihot – Utilisima (tapioca plants) from a farm

and observed it through a moon phases and found that sections cutting soon and found more cavities when

compared to sections taken after full moon, and also observed that fungi and insects attacks on the sections

are more after new moon.

Next we collected 1 cm long tender stems each day for 3 moon phases from Eupatorium, Banhenia,

ManihotUlitisima plants which is abundant in our area and kept formalin before examining the sections

using a compound – microscope. We observed that the number of cell layers formed in the plants is more

during the new moon and successive days. We also collected the sap from live tapioca plants everyday

during a moon phases and found that the weight of sap collected is more during new moon days.

During new moon days we experimentally proved that capillary rise of water is more in the soil.

By taking all these result into consideration, we concluded that during new moon and successive days

sapwood (outer sections) of the plants become more tender than other days and is vulnerable to the attacks

of insects like furniture beetle, chlolorophorusannularis, stromatiumbarbtum, Lyctusafricans etc. which

attacks the stem and timber. On the new moon day moon and sun are present in the sky all day long and

the attractive force (even though it is very small compared to Earth’s gravitational force) of moon and sun

may cause change in the biological rhythms of plants.

By sharing these traditional knowledge scientifically among the society, will help to decrease the

excessive use of chemical pesticides at the time of cultivation which is done not-considering the effects of

moon phase.

ABSTRACT

Objectives:

To assess the efficacy of scientific preventive measures to eradicate sand flies spreading Kala Azar.

Introduction:

The term 'Kala Azar' also known as black sickness or black fever (Visceral leishmaniasis) is an

infectious fatal parasitic disease spreading by a small fly called sand fly with the size of only one by third

of the mosquito. The disease is endemic in West Bengal, where it was first discovered, but is seen at its

most deadly in Northern East Africa.

The symptoms of the disease are fever/ enlargement of the spleen, enlargement of the liver is seen

as well. The blackening of the skin that gave the disease its common name in India, doesn't appear in most

strains of the disease, and the other symptoms are very easy to mistake for those of malaria. Misdiagnosis

is dangerous, as without proper treatment the mortality rate for Kala Azar is close to hundred percent.

North Bihar, India, including Purnea, Kishangang, is the endemic zone of the disease.

Methodology:

Analyzing the cause of Kala Azar/ we visited Manantheri, Thondileri colony in Kannur district,

Kerala to meet Shinoj, Kala Azar affected boy. Discussion with his parents and others, we did a survey

about the aforesaid disease. From this, we analyzed that it is due to sand fly, which are tiny flies measuring

3-6mm long by 1.5-3 mm in diameter. The adult female sand fly is a blood sucker, usually feeding at night

on sleeping prey. The larvae grow in warm, moist organic matter, such as old trees, unplastered house

walls or contaminated stagnant water, making, them hard to eradicate.

In that colony, we surveyed 15 houses. Among these, 10 houses' walls were not plastered, one

house partially plastered. Other 4 houses were built with bricks. Most of the houses people were suffering

from fever, skin diseases and cough etc. Nearby 4 houses were occupied by other state people. We talked

to Shinoj's parents and thoroughly analyzed his case and could understand that 12 year Shinoj was addicted

in alcohol and tobacco. Moreover, they were living in a contaminated situation. We discussed the case with

the health workers and did vector study between 7am to 9am. From that we got 3 sand flies. The vector in

that situation was 3/2=1.5. After one week we conducted same experiment in ward 11, were Shinoj was

staying. In this location, majority of the innate are non Keralites. From there we collected the vector

between 7.30am to 9pm. Every half an hour, we got 103 sand flies. The vector density was 103/2 = 51.5.

From these experiments we assessed that the origin of the sand flies were unplastered walls, stagnant dirty

water and congested dwelling places of non Keralites especially Bengalis. Shinoj schooled in Pattuvam.

We analyzed the vectors from there and we were not able to find even a single sand fly in the vector study.

We did the same survey in Alappadamba panchayat, where there were no unplastered houses. So,

we did the experiment in dirty cow shed with stagnant water. From two houses' cowsheds we got 7 sand

flies within two hours. So, we concluded in future, our area also will be under the threat of this disease.

Conclusion:

As with many diseases in developing nations, including trypanosome and malaria, traditional

treatments like DDT and mosquito odomoze are used. These are hazardous to health. So we talked with

many ayurvedic doctors and decided to manufacture a medicine with the plants which are not attracted by

the flies. We prepared a herbal decoction by mixing boiled coconut oil with solution of Arutha's leaves.

We applied the herbal to the sand flies instead of its death they felt uneasiness. Next we prepared a

medicine by using spotted glyrecidia or Seema Konna, Forest Camphor or KaatuKarpooram, Thulsi,

RutaGraveolens or Arutha, CylonSlitwort or Thumba, Red Ivy or Muri Kooti etc. It is one of the best

remedy to alienate sand flies. Then we formed an emulsion by using custard apple's leaves plus neem oil it

is also best way to alienate the sand flies. Next week tested the herbal medicine to the flea affected cow,

the result was positive. From the aforesaid experiment we understood that this medicine is the best one to

eradicate all the flies including sand flies. To test this medicine how far it is effective to the human beings,

we distributed the medicine and surveyed 40 houses, the result was positive.

Our project is under the consideration of health department and handed over to epidemiology

department. On the basis of this project, Kannur district Collector ordered to enquire about this disease

among the aadivasi colony. We handed over the copy of this project to education minister C Ravindranath.

Minister remarked that we must be more careful about this disease like other epidemic diseases.

ABSTRACT

On June 5th we were planting trees in our school compound as a part of World

Environmental Day. We just noticed that KSEB employees were cutting away tree branches near either

sides of the electricity line passing nearby. It seemed like a controversy to us that on one hand we were

planting trees to protect the nature, and on the other hand they were cutting away tree branches. Our

concern was shared with KSEB overseer and invited him to be a part of our discussion. We were able to

understand many facts about this and to make things further clear an interview was conducted with the

Engineer, Vellur Electrical Section Office and information’s were collected and recorded.

Out of the daily electricity requirement of 65.6 million units, only 14 million units are

produced here. The remaining is brought from different external sources and agencies by paying enormous

production cost.

According to KSEB statistics, electricity wastage by transmission & distribution is about

14% to 18%. KSEB Engineer pointed out that transmission loss is beyond our control however wastage

during distribution could be reduced with our effort and care. He also said that distribution wastage is

comparatively very high in rural areas. The main reason behind this is the tree branches and plants

touching the electricity lines causing earth leakage. We came to know that there were no scientific studies

known to be conducted on this topic and the amount of electricity lost during distribution by earth leakage

is yet to be accounted. These facts lead us to this study.

The electricity line from Thavidissery South transformer is 6.4 km in length. We discovered

that 8 coconut palm leaves, 23 tree branches and 11 vine plants were touching the lines. Among these the

coconut palm leaves were found to be touching the line with maximum area. So it was decided to estimate

the amount of electricity lost by earth leakage through these coconut palm leaves. Under the leadership of

KSEB overseer the leakage was measured and tabulated. The average amount of electricity lost this way

was 0.4587 A (84.87 W).

This amount of electricity is more than that is needed to light 8 LED bulbs of 10W each for

1 hour. On an average an electricity of 24x84.87=2036.88W is lost every day by earth leakage through

coconut palm leaves. This is more than enough to light 203 LED bulbs of 10W each for 1 hour. From the

above statistics on an average 16,295 W electrical energy is lost by earth leakage through 8 coconut palm

leaves. Considering an average family energy usage this is enough for usage in 5 such families for a day.

It is always better to prevent wastage of each single unit of electrical energy than to produce double

of it. To share this concept with the society, to make them aware and to prevent the electricity loss through

earth leakage we moved forward to remove earth touching branches and plants from this 6.4 KM

electricity lines form Thavidissery South transformer. This was accomplished with the help and support of

School PTA, villagers and KSEB. We were able to completely remove earth touches from the area and to

save 16,295 W electrical energy lost every day.

For the generation of electricity we are highly depending on natural resources like fossil fuels. In

the context of a state like Kerala trailing towards severe energy crisis, if it is possible to ensure maximum

usage of electrical energy through conservation and prevention of wastage it would be a milestone towards

reduction in exploitation of natural resources, thereby protecting the environment for a better tomorrow for

the coming generations through sustainable development.

As a continuation of our work the rural remote village, Thavidissery was declared as Kerala’s first

“Line touch electricity wastage less village” by Sri C. Sathyapalan, Payyanur Block Panchayath president

on 02/11/2016 at a grand meeting held at GHS Thavidissery.

Inspired from this, Sri. Adv. SasiVattakkovval, Hon. Payyanur Municipal Chairman organized an

Energy conservation group at the municipal level and has started his efforts to make Payyanur as “Kerala’s

first line touch earth leakage less town”. Honorable Kannur Dist. Collector has taken the actions to form

Energy Conservation Form at the district level. Honorable Minister of Electricity &Devaswom, Sri

KadakampallySurendran congratulated us at his chamber at Trivandrum for our effort in energy

conservation for a sustainable tomorrow. Also he has begun the action to make this project work for the

entire Kerala state.

ABSTRACT

Fossil fuels are the main source of energy used in almost all the vehicles that run on the Indian

roads. As the maintenance works of these roads are not properly done, most of the roads are in a pathetic

stage, with uneven, broken tars here and there. This inquisitive project aims to conduct a comparative

study on the cost of excess fuel used in the vehicles that run on such uneven, dilapidated roads in the day

with cost of maintenance and tarring of the same. The study opens out the urge conservation of energy

.The selected road, which is the main district road that connects NH-47 and the MC road. The width of the

road is 7 m. A part of the road is rather fairly tarred in BM&BC way. Part of it about10km is utterly in

broken stage with a lot of pits.

Observation, survey, interview and experiments are the different method used to complete this

project .The study was conducted in the selected road from 6 am to 10pm. At first, we collected a list of the

complete vehicle that passed through the road within the time period. It is then categorized on the basis of

cubic capacity .Along with this, conducted interview with 105 drivers of these vehicles about the mileage

of vehicles and their views regarding the gear changes and all. Then collected data from the PWD road

Engineer about the different type of tarring, cost of tarring, effectiveness, need for road care etc…Also

collected the information from experts of this field.As a result of these studies we could arrive at the

conclusions given below.

1. Because of the pathetic condition of the 10 km road taken under study, it was found that 1211.53liter

diesel and 418.13liter petrol was used in excess in one day.

2. If this 10km is in properly tarred (BM&BC work) for 5 years the cost of tarring will be 10 crores

(1rore/km) whereas the cost of excess fuel needed for the vehicles is found to be 178887888.82(17 crore

,88 lakh, 87thousand and eight hundred and eighty eight) that is an excess use of 2211042.25(22 lakh

11thousand 42.25)Liter diesel and 763087.25Ltr petrol.

The availability of fossil fuel is decreasing day by day .It is our duty to preserve each drops of

fossil fuel for the coming generation.Unbelievable ,it at a small distance(10km) of road, this much fuel is

wasted in one day, think about the energy wasted in one day along the Indian roads.

ABSTRACT

Objectives: More and more comforts, more and more worries......stands even when paving materials are

used to adorn the beauty of the houses as it is one of the reasons for Global Warming.

To analyse whether paving materials used in the courtyard affect climate change.

Work plan: Duration of project is 58 days.(sept 3rd 2016 to oct 31st 2016)

Experiments: There are four stages in the Project

1. Selection of Paving Materials: Tightly paved interlocks, Evenly gapped interlocks, Gravel, Soil,

Laterite stone

Measuring Units: Temperature of Soil, Temperature of Atmoosphere, Temperature of Water, Rate of

Evaporation,

2. Interview: Among Professors,Environmentalist,Senior citizens and Medical Officer

Aim of survey: To know about Interlocks and heat it produces in the atmosphere and health hazards.

3. Curative Measures: Differently paved Interlocks

Interlock 1: Laid on gravel with 0.5cm gap and 1.5cm gap

Interlock 2: Laid on gravel with wide gaps where in water flown pipes passed through and

covered with soil and planted grass.

4. Distribution of pamphlets, Interactive Sessions, Awareness on how Interlocks affect the

atmospheric temperature.

Results: Interlock two produces less atmospheric temperature when compared to Interlock one.

Conclusion: The paving materials such as Interlocks can adversely affect the climate due to theirproperty

of high heat absorption. Soil is the less heat producing material when compared to anyother paving

material. Water flown pipes in between the interlocks could help to reduce heat ofinterlocks and also save

electricity and gas consumption. And also it can be made as a source ofhot water.

ABSTRACT

Beautiful white coloured flour called Maida is a silent Killer for human beings. According to health

surveys most of the diseases are because of the use junk food. Maida is the villain for most of the diseases.

Maida is made from the inner part of wheat grinded and bleached with benezoyl provide to form white

powder. This one is again mixed with Alloxan to form Maida. Because of this process Maida is very soft,

and it has already gone through the dangerous chemical processing. A food fest was conducted in our

school in the month of June. And students brought many food items but most of them were made of Maida.

At this context we feel it is necessary to study about the consumption of Maida in our locality. A

preliminary survey was conducted among students of various classes such as 8, 9, 10 standards of our

school, to analyze their food habits and one day diet. This survey aimed to identify whether they use Maida

or Maida products in their diet. We also did experiments to measure the gluten content of wheat flour,

Maida flour and Barley and also various brands of wheat flour. Among the samples of various brands of

wheat flour, Ashirvaad multi-grain flour with low glycemic index value showed higher gluten

content/value. The survey was followed by a secondary survey in the neighbouring area of school

premises. This survey in 100 residents revealed that most of the residents are including maida for preparing

food and bakery items. The present study area is Chalappuram in Kozhikode district and most of the

residents are educated, about 65% of the residents under study includes Maida and Maida products in their

diet and most of them are diabetic. We plan in such a way that we do educate the residents regarding

disadvantages of consuming Maida flour. The consequence of usage of Maida will be explained in suh a

way that our project makes an impact on the wrong food habit of the selected residents. It is difficult for us

to completely avoid Maida, but by educating we can bring down the consumption of Maida.

ABSTRACT

We need several forms of energy in our daily life. Among the various forms we largely depend on

Electrical energy. In our daily life we use several electrical appliances for our domestic purpose and social

life. But the fact is that energy once used results in loss. Wastage of electricity willseverly effect the

coming generation. Common people are not bother about the consumption of each electrical appliances.

They are depending only the advertisements. They are not compairing the usage of electricity with the

product of different companies. They are considering only MRP of the product. Most of the cheap

appliances are consuming more energy than others. Those products are not profitable.

So we think that, if each people get information about the energy consumption of each instrument,

they should be careful about the conservation of energy. By using energy efficient appliances we can

conserve electrical energy.

Survey

A survey was conducted with the help of a questionnaire and observation, for the effective study of

the topic. The data was collected and consolidated. The electrical appliances which consuming high

electricity were listed. Such types of appliances are commonly use in our houses. The people are not bother

about the usage of high energy. They are attracted by the advertisement of different companies. Survey was

conducted at the houses in KulakkadaPanchayath.

Interview

A detailed observation schedule was prepared and the analysis of the data collection was done. Related

information is collected from some reference books and internet. An interview with an expert in the field,

Mr.JagadeeshAsst.Engineer,KSEB, Kulakkadawas also conducted. It was very helpful to get information

about this theme.

Experiment

An experiment was also conducted with the help of our science teacher and guide teacher. We recorded

the heat (temperature) produced by an incandasentbulb(60W),CFL(15W)and an LED(7W) using a

thermometer. Thermometer reading noted every 5 minutes for 20 minutes. Incandasent bulb produced more

heat and LED produced less heat. The room temperature will increase when an incandasent bulb uses.

We also noted the different ways we waste electricity while using it. Old wiring materials in the

house causes a good amount of power loss. In many houses people use unnecessarily high-watt electrical

appliances. This also causes energy wastage. About 65% of families are wasting a high amount of

electricity. It is also noted that during festivals also, there is a large amount of electricity loss.

Seminar

A seminar was also conducted on 3rd October 2016 at the school hall with the help of slide

presentation to inform the Science Club Members. Due to the hardness of this issue, posters are prepared

and exhibited for the attention of the public.

Awareness programme

An awareness programme was conducted. The programme was led by

Mr.UnnikrishnanNair(Resource person, Energy Management Centre).

Conclusion

By knowing the energy consumption of each appliances, every people can control the consumption of

electricity. Energy efficient appliances should be use. Star labelling is very important. Use of CFL, and

LED bulbs will be promoted. The habit of using all electrical lamps and other high-watt appliances at the

peak hours must be discouraged. We should create awareness among our family members and our

neighbourhood on Energy conservation techniques. This project highly emphasis upon “The urgency of

conserving Electrical Energy.”

According to our APJ:“Energy efficiency is the fifth fuel.......”

“Conservation is more effective than production.”
