The document is a presentation on Jatropha curcas oil and its potential as a future source of biodiesel. It discusses India's growing dependence on imported crude oil and the need for an alternative fuel substitute. Jatropha is identified as a promising non-edible oilseed crop that can be grown in dry lands and produce oil for biodiesel production. The presentation covers Jatropha cultivation areas in India, biodiesel production methods from Jatropha oil, engine performance and emission characteristics of biodiesel blends, and concludes that biodiesel is a renewable and ecofriendly diesel substitute but is more prone to oxidation over time without proper stabilization additives.

By the increase in demand of fuel the resources are not as many to full control the demand of the world and the known reservoir wont last forever there fore an alternate energy source is required to fulfill the world fuel demand.
Biodiesel is an alternative fuel of diesel, is described as fatty acid methyl ester from vegetable oils or animal fats. The main objectives of the present work is to reduce higher viscosity of Pongamia pinnata (Karanja) oil using esterification followed by transesterification and to assess the performance and emission characteristics of diesel engine. The important properties of engine fuel such as density, viscosity, flash point and calorific value of Karanja methyl ester were compared with diesel fuel. Various proportions of Karanja oil methyl ester blends (10%, 20%, and 30%) were used for conducting the performance test at varying load conditions. Engine parameters such as brake specific fuel consumption, brake thermal efficiency were calculated and emission parameter such as emission of carbon dioxide, hydrocarbons and oxide of nitrogen gases in exhaust were recorded. By using Karanja oil methyl ester blends with diesel fuel, the result showed that the brake thermal efficiency of biodiesel blends with diesel fuel wee less as compared to diesel fuel. Fuel consumption was increased with increase in blend proportions. It is found that the emission level of CO and HC level decreased with increased in blend proportion in diesel fuel. NOx emission increased with increase in blend proportion in diesel fuel. The test results indicate that biodiesel B-20 and lesser can be used as an alternative without any modifications of diesel engine.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

Conclusion
3. Total crude oil consumption of the country is 184.68 MT in 2007-08.
Out of which 80% of the total demad is imported.
Import value is 6,06,800 crore.
Crude oil is also creating environmental problems.
Therefore there is need to go for substitute of petroleum diesel.
Substitute of petroleum diesel:
Straight vegetable oil
Edible oils
Non edible oils
72.5 % of the total edible oil demand is importing in the country.
4. OBJECTIVE OF STUDY
To study the fossil fuel scenario with respect to petroleum
diesel, fuel properties of biodiesel resuorces for biodiesel
production, process for its production, etc.
Study the effect of biodiesel on the performance of IC engine
To study the oxidation stability of biodiesel.
5. WHY JATROPHA
Jatropha can be grown in arid zones (20 cm rainfall) as well as in higher rainfall
zones & even on land with their soil cover.
Under the national biodiesel program Jatropha is selected to fulfill the national need
of biodiesel.
Upto 2012 government is planning to substitute biodiesel from jatropha in
commercial use (20% of the total petroleum diesel ).
Jatropha specie is scientifically developed to give maximum yield.
It is a quick yielding species even in adverse land situations viz degraded & barren
lands under forest & non forest use, dry and drought prone area, marginal lands
even an alkaline soils & also as agro forestry crops.
Jatropha removes carbon from the atmosphere stores it in the woody tissues &
assists in the build up of soil carbon.
Various parts of the plant are of medicinal value.

23. CONCLUSIONS
Biodiesel is an ecofriendly and renewable fuel substitute of diesel.
Research has indicated that upto B20, there is no need of modification in
engine.
The engine performance evaluation has found that brake specific fuel
consumption for B100 was 14.8% higher than diesel for biodiesel from Jatropha
oil at full load, thereby indicating the use of 100% biodiesel can produce same
output of energy using higher amount of biodiesel and therefore deserve to
become the “On Farmer Fuel” where farmer can grow his own resource,
convert to biodiesel and use in agricultural sets itself without the need of any
diesel for blending.
The brake thermal efficiency is found higher upto B30 in comparison to diesel
while BTE of B100 (24%) was almost equals to diesel (24.5%) for JOME.
The basic problem with biodiesel is that it is more prone to oxidation resulting
in the increase in viscosity of biodiesel with respect to time which in turn leads
to piston sticking, gum formation and fuel automization problems.
