Phytochemical studies were carried out on the plant parts of Jatropha curcas (L.) and Azadirachta indica (A. Juss) found in the South Eastern parts of Nigeria with a view to highlighting their pre-existing secondary metabolites which have varieties of biological activities attributed to them. Qualitative and quantitative analysis of seven secondary metabolites (alkaloids, tannins, saponins, fla...

This paper presents a pre-mixed combustion model for diesel and Jatropha oil blends combustion studies. Jatropha oil blends are considered as a mixture of diesel and Jatropha oil. CFD package, FLUENT 6.3 is used for modeling the complex combustion phenomenon in compression ignition engine. The experiments are carried out on a single cylinder, four strokes, water cooled direct injection compress...

This study seeks to analyze the benefits, as well as the likely risks of cultivating Jatropha curcas in small production units of rain fed lands in Yucatán. In order to analyze the possible development of local artisanal agri-industry in the context of policies related to biofuels in Mexico, interviews with key informants were made to identify the agricultural potential of Jatropha c. in monocu...

Thermochemical conversion of non-edible biomass offers an efficient and economically process to provide valuable fuels and prepare chemicals derived from biomass in the context of developing countries. Pyrolysis has advantages over other thermochemical conversion techniques because it can convert biomass directly into solid, liquid and gaseous products by thermal decomposition of biomass in the...

The water footprint (WF) of a product refers to freshwater consumed during production (1). We calculated bioenergy WFs assuming crop water requirements are met (2); Jongschaap et al. (3) correctly point out that this is not always true, giving an example for jatropha grown under poor, rainfed conditions in South Africa. Yields are generally expressed in ton/ha, but, when water is scarcer than l...

Cost and limited reserves of conventional fossil fuels have intensified the search for alternative fuels for use in internal combustion engines. A possible alternative engine fuel is vegetable oil because it is a clean burning, renewable, non-toxic, biodegradable and environmentally friendly transportation fuel. It can be used in a neat form without any modification of the engine. Vegetable oil...

for determining the oil content, seed and fruit characteristics of ethiopian jatropha provenances, the study was conducted in five regions of ethiopia namely southern nation nationalities peoples regional state, amhara region, tigria region, oromia region and benishangul gumuz regions, where jatropha is found abundantly. a total of 23 zones, 36 weredas and 40 sampling sites were considered from...

Geminiviruses are a group of plant viruses that contain circular single stranded (ss) DNA genomes encapsidated in small twinned icosahedral capsids .The virus DNA A plus strand encodes the coat protein (CP/AV1) essential for viral transmission by whiteflies (Bemisia tabaci)[4]. Jatropha has been found to have strong molluscicidal activity and the latex to be strongly inhibitory to watermelon mo...
