Food insecurity throughout Sub-Saharan African countries is a common problem and needs sustainable solution to improve crop yield production, rather than agricultural area expansion. Vegetables are important in sustaining the livelihood of many small-scale subsistence farmers contain vitamins, minerals, essential amino acids, none has cholesterol most low fat calories. also high fiber, which he...

During spermatogenesis, spermatozoa lose many of the organelles that most somatic cells possess (such as endoplasmic reticulum, lysosomes, and most of the cytoplasm) reducing the “baggage” they need to carry en route to the oocyte. The primary function of a spermatozoon, fertilizing an oocyte, is an integrated set of processes, which require multiple cell attributes. Therefore, although the spe...

Removal and recovery of nitrogen with the Aqua2®N-process demonstrated The overall goal RE-Fertilize project was to demonstrate a new removal process for nitrogen, producing product suitable fertilizers, example. In project, demonstration plant has been built, in operational environment rate >95% ammonium nitrogen. produced sulphate evaluated its agronomic effect proven. A conceptual design ...

One of the important commodities that are widely consumed to meet nutritional and food needs, especially vegetables, is tomato (Solanum lycopersium). The need for tomatoes increasing both in quantity quality. But until now vegetables quality difficult using conventional agriculture. For this reason, application biological fertilizers have potential reduce use inorganic able efficiently fertiliz...

Silicon (Si) is the most abundant element on earth’s surface after oxygen. Si can be found in minerals, electronic chips, cosmetic products, and plants for instance. Here we review Earth's terrestrial cycle, focussing ecosystem services. We show that silicon participate inherent manageable properties involved all As records of past, phytoliths useful parameters cultural provisioning services be...

A purported global decline in sperm counts has been a source of controversy since the early 1990s. Numerous studies performed since then, as well as reanalysis of the original data, show either no changes, or even increases, in sperm concentrations over time. In this review, we discuss the 1992 meta-analysis that initiated the continuing debate on whether sperm concentrations are declining, and...

TNFα is a pleotropic cytokine that exerts its effect in many cell types via TNFR. In spite of their well-established roles in various biological events, neither TNFα nor TNFR is essential for normal mouse development, and mice deficient in either, like CARP2-null mice, developed normally and exhibited no defects without a challenge [6,7]. Similarly, deletion in mice of c-IAP or c-IAP2, proteins...
