Rice has become a major staple cereal in sub-Saharan Africa. Currently, upland rice cultivation is expanding particularly in rainfed areas where the root parasitic weed Striga hermonthica, a major constraint to cereal production, is endemic. Laboratory, pot, and semi-controlled open air experiments were performed to evaluate resistance of selected rice varieties in Sudan to a resident S. hermon...

On voiding cystourethrography ( VCU ) not a few patients embarrass the examiner as they can not void on an X-ray table from shame. To allow the patient to void without such embarrassment, we developed a new type of urinary pot named the " VCU pot", which is a gourd -shaped pot made of a vinyl chloride plate. VCU pot is put between the patient's thighs and suspended with a pair of strings from t...

The one-pot synthesis of a target molecule in the same reaction vessel is widely considered to be an efficient approach in synthetic organic chemistry. In this review, the characteristics and limitations of various one-pot syntheses of biologically active molecules are explained, primarily involving organocatalytic methods as key tactics. Besides catalysis, the pot-economy concepts presented he...

The seeds of cotton (Gossypium hirsutum) fall among the lesser known oil seeds. Cottonseeds are not normally consumed in their natural state due to their gossypol content, an antinutrient. The effect of processing on the sensory characteristics and chemical composition of cottonseed and its extract was studied by subjecting the cottonseed extract to heat treatment (boiling) and the cottonseed t...

The acidic agent (SO3H) was stabilized on the silica coated Fe3O4 magnetic nanoparticles to produce Fe3O4@SiO2@Pr-SO3H, as a heterogeneous acidic catalyst, was designed, and then fully studied and characterized by FT-IR, XRD, TGA, DTA, TEM, and SEM analysis. Subsequently, the catalytic activity of Fe3O4...

Women are involved in planting, transplanting, weeding, harvesting and processing activities in paddy cultivation system. These operations are most drudgeries activities performed by them. During these operations the women face many physical and physiological problems. Keeping this in view the physical strain with respect to working heart rate (WHR), Oxygen consumption rate (OCR), Energy expend...

A capability to determine the availability of nitrogen in organic amendments is necessary to ensure that such materials will provide sufficient nitrogen to the growing crop and cause minimal environmental degradation. Greenhouse bioassays were used to evaluate N availability of organic by-products, including several employed in the field study of this research. Tall fescue was grown in greenhou...
