Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...

Thymol, an important and advantageous component of many essential oils, has been applied as an antimicrobial agent in animals. To increase the duration of action of this compound in ruminants, it was decided here to prepare a controlled release carrier for thymol. Hydroxy propyl methyl cellulose (HPMC) and ethyl cellulose (EC) were used as the matrix polymer here. Mixtures of thymol with eight ...

The Haber–Bosch process for the commercial production of ammonia demonstrated in 1913 was a watershed event in the mass production of urea, the principal nitrogen fertilizer for modern agriculture. Today, thanks to the so-called “green revolution” starting in in the 1960s, nearly half of the world population relies on increased crop yields, through the use of nitrogen fertilizers, to access aff...

Hydralazine has been used for the treatment of hypertension since 1950 (Gross et al., 1950), but only since the introduction of beta-adrenoceptor blocking agents has its use again become popular (Koch-Weser, 1976). Originally, hydralazine was given in four divided doses, but it has been shown to be equally effective and without increased side-effects when given by twice daily dosage (O'Malley e...

We report on the formation of hydrogel monoliths formed by functionalized peptide Fmoc-RGD (Fmoc: fluorenylmethoxycarbonyl) containing the RGD cell adhesion tripeptide motif. The monolith is stable in water for nearly 40 days. The gel monoliths present a rigid porous structure consisting of a network of peptide fibers. The RGD-decorated peptide fibers have a β-sheet secondary structure. We prov...

glycation is a protein modification, which results in a change in a protein structure. glycation is believed to be the etiology of various age-related diseases such as diabetes mellitus and alz-heimer’s disease (ad). activation of microglia and resident macrophages in the brain by glycated proteins with subsequent oxidative stress and cytokine release may be an important factor in the progressi...

A slow-release fertilizer is important to improve soil conditions and enhances food security through continuous plant supply. With urea as a nitrogen source, kaolin carrier, acrylic acid reaction monomer, potassium persulfate an initiator, N, N '- methylene bisacrylamide crosslinking agent, under the action of cyclohexane sorbitan monostearate, based was synthesized by reverse suspension method...
