Tobacco (Nicotiana tabacum L.) is an important cash crop to most farmers in Western and Central Zones of Tanzania [1]. However, the yield adversely affected by low soil fertility [2]. The nutritional requirement for provide potential yield-is high requires huge amount nitrogen (N), phosphorous (P), potassium (K) proper growth development roots [3–7]. After being transplanted fields, tobacco see...

X-ray crystal structures of two [(diphosphine)Au2 Cl2 ] complexes (in which diphosphine=P-Phos and xylyl-P-Phos; P-Phos=[2,2',6,6'-Tetramethoxy-4,4'-bis(diphenylphosphino)-3,3'-bipyridine]) were determined and compared to the reported structures of similar atropisomeric gold complexes. Correlations between the Au⋅⋅⋅Au distances and torsional angles for the biaryl series of ligands (MeOBIPHEP, S...

This paper reports the vermicomposting of food industry sludges (FIS) mixed with different organic wastes employing Eisenia fetida. A total of 10 vermicomposting units containing different wastes combinations were established. After 15 weeks significant increase in total nitrogen (N(total)) (60-214%), total available phosphorous (P(avail)) (35.8-69.6%), total sodium (Na(total)) (39-95%), and to...

blood sulfhemoglobin (s-hb), total haemoglobin and phosphorous (p) level and blood cell count in 33 matches industry workers of azar abhar, who were exposed directly or indirectly to chemical agents used in the factory (subjects), were measured. the results were compared with the result of the same measurement on 14 farm workers of the region (control) and were analysed. in this study the effec...

Case A. A. 16 years old, female referred to our service for evaluation of hypercalcemia. The patient presented with fracture at the thoraco-lumbar spine after being accidentally slipped on the floor. She sought consult at a private hospital and an orhtopedic brace was applied. Three months after the incident, the patient complaint of limping and eventually with difficulty in ambulating. She was...

The feasibility of edge-functionalization of graphite was tested via the model reaction between pyrene and 4-(2,4,6-trimethylphenyloxy)benzamide (TMPBA) in poly(phosphoric acid) (PPA)/phosphorous pentoxide (P(2)O(5)) medium. The functionalization was confirmed by various characterization techniques. On the basis of the model study, the reaction condition could be extended to the edge-functional...

Transition metal carbides and phosphides have shown tremendous potential as highly active catalysts. At a microscopic level, it is not well understood how these new catalysts work. Their high activity is usually attributed to ligand or/and ensemble effects. Here, we review recent studies that examine the chemical activity of metal carbide and phosphides as a function of size, from clusters to e...

Anion exchange membranes (AEM) based on polyphenylene oxide (PPO) suffered quaternary-ammonium-cation-site degradation in alkaline environments. Surprisingly, the degradation rate was considerably faster in the presence of molecular oxygen. We postulated that the AEM cation-site catalyzes the reduction of dioxygen by hydroxide ions to yield the superoxide anion radical and the highly reactive h...

The objective of the presented work was to study and compare different biochemical parameters of bone mineralization and renal function in preterm and term infants. The study included 150 newborn babies admitted in the neonatal unit, of the hospital. The enrolled neonates were divided into study group [further divided into subgroups according to their gestational age (GA) Group-IA (30-32 weeks ...
