Recently biodiesel (fatty acid methyl ester, FAME – in Germany mainly rapeseed oil methyl ester as a neat fuel, which means B100) became an important alternative fuel on the German and the European markets. Approximately 1,200,000 tons were sold in Germany in the year 2004 (VDB, 2004). This is more than 50 % of all biodiesel that is sold in the European Union (Observ’ER, 2004). Today biodiesel ...

A new method has been developed to rapidly determine the total inorganic carbon concentration (gaseous [CO2] + aqueous [CO(2)] + [HCO3-] + [CO3(2)-]) in developing seeds. Seeds are rapidly dissected and homogenized in 1 N HCl in gas-tight vials. The headspace gas is then analyzed by infrared gas analysis. Developing rapeseed (Brassica napus L.) and soybean [Glycine max (L.) Merr.] seeds were an...

New N,N-disubstituted β-amino acids and their derivatives with thiazole, aromatic, and heterocyclic substituents were synthesized from N-phenyl-N-thiocarbamoyl-β-alanine by the Hantzsch method; derivatives with hydrazone fragments were also obtained. Some of the synthesized compounds exhibited discrete antimicrobial activity, and 3-[(4-oxo-4,5-dihydro-1,3-thiazol-2-yl)(phenyl)amino]propanoic ac...

BACKGROUND Tocopherols are important antioxidants in vegetable oils; when present as vitamin E, tocopherols are an essential nutrient for humans and livestock. Rapeseed (Brassica napus L, AACC, 2 n = 38) is one of the most important oil crops and a major source of tocopherols. Although the tocopherol biosynthetic pathway has been well elucidated in the model photosynthetic organisms Arabidopsis...

in order to study the effects of organic and inorganic nitrogen sources on quantitative and qualitative characteristics of three winter rapeseed cultivars, a field experiment was carried out as factorial arrangement in complete block design with three replications in agricultural and natural resources research center of markazi province, arak, during 2008-2009 growing season. three rapeseed cul...

twenty-four holstein male calves (bw=217±57kg) were employed to evaluate the effects of rapeseed oil supplementation on growth, carcass as well as on meat quality and fatty acid content of longissimus thoracis muscle in a completely randomized design. the calves were divided into three groups and allocated to three diets of: a corn/barley-based diet (c); a diet containing 2% (dm basis) rapeseed...

Rapeseed is the second largest plant protein resource in world with an ideal profile of essential amino acids. meal (RSM) one by-products rapeseed oil extraction. Due to anti-nutritional components (glucosinolates and fiber) poor palatability, RSM limited livestock diets. Recently, how decrease factors improve nutritional value has become a hot topic. Therefore, major have been reviewed emphasi...

The heating value of fuel is one of its most important physical properties, and is used for the design and numerical simulation of combustion processes within internal combustion (IC) engines. Recently, there has been a significant increase in the use of dual fuel and blended fuels in compression ignition (CI) engines. Most of the blended fuels include biodiesel as one of the constituents and h...
