The use of agricultural chemicals is an important aspect of animal production. Animal scientists have played an active and varied role in the recent and rapidly developed use of these chemicals. Although approval to use agricultural chemicals has always been based on both efficacy and end point residues, increased consumer concerns during the past one and one-half decades about the safety of th...

This study aimed to estimate the amount of biomass energy that can be acquired from crop residues in Eritrea, a country horn Africa with population 6 million and having national income per capita is around 150 US dollars. It’s an agricultural country. The potential was calculated by considering calorific values available residue. For year 2015, total value estimated approximately 1332.34TJ. Acc...

In this study, pesticide residues in sauce manufactured from agricultural products were examined. A simultaneous multiresidue analysis for 260 pesticides samples was performed using liquid chromatography with tandem mass spectrometry (LC-MS/MS). The QuEChERS AOAC 2007.01 (quick, easy, cheap, effective, rugged, and safe) selected as the most suitable protocol routine determination of residues. l...

Surface characteristics of printing substrates are the utmost importance to all types paper that interact with ink. During processes, behaviour liquid phase (ink or dye) on is directly defined by cellulose-based surface. The printed ink spreads and penetrates more into fibres when surface rougher permeable. Contact angle measurements sessile drop method considered most appropriate for determini...

Bangladesh is a middle-income country. With the development of industrial and agricultural sectors, demand for petroleum-based fuels in transport sector has been steadily growing. Diesel, petrol, octane (C8H18), liquid petroleum gas (LPG), compressed natural are mainly used as transportation sectors Bangladesh. The government imports LPG well refined, crude, furnace oil from abroad to meet coun...

Routine measures used to control the larval stages of non-statutory leafminer species in the United Kingdom rely largely on either the use of the braconid parasitoid Dacnusa sibirica Telenga and the eulophid wasp Diglyphus isaea Walker as, for example, in tomato crops, or on chemical insecticides for control in leafy salad and ornamental plants (Garthwaite and Thomas, 2001). The availability of...
