the green revolution fulfilled the food demand of crowded millions. from the time of green revolution to till date high yielding and fertilizer responsive varieties have evolved to increase the production per unit area. to improve the productivity only major nutrients are concentrated almost in all crops. though the importance of micronutrient realized during past decades in most of the crops b...

We are concerned with polynomial ordinary differential systems that arise from modelling chemical reaction networks. For such systems, which may be of high dimension and depend on many parameters, it is frequently interest to obtain a reduction in certain parameter ranges. Singular perturbation theory, as initiated by Tikhonov Fenichel, provides path toward reductions. In the present paper we d...

Objective: The purpose of this study is to determine the effects COVID-19 infection on individuals with mannose binding lectin deficiency. Methods: An electronic medical records search was conducted for MBL deficiency and positive tests from March 2020-August 2022. Individualized chart analysis statistical performed. Results: Thirty-three people in WVU medicine health system carry a diagnosis w...

One of the crucial elements for livestock and human nutrition is selenium and its deficiency or toxicity can harm human and livestock health. The present study is designed with the aim of studying the effect of different levels of selenium fertilizer (Selcote-Ultra) and cow manure on the uptake of selenium in tall fescue. For this purpose, a pot experiment with complete randomized block design ...

The necessity of a metal ion for the activity or synthesis of specific enzymes may be revealed by growing the organism under conditions of the metal deficiency and comparing its enzyme systems with those of normal tissue. Waring and Werkman (1) reported that iron deficiency in Aerobatter indologenes resulted in the suppression of a number of enzymes. Zinc deficiency results in increased acid pr...

in this paper, we give a characterization of strongly jordan zero-product preserving maps on normed algebras as a generalization of  jordan zero-product preserving maps. in this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly jordan zero-product preserving maps are completely different. also, we prove that the direct p...

common variable immunodeficiency (cvid) and selective iga deficiency (sigad) are the most common primary antibody deficiencies. these two diseases may have coincidence in one family and sigad can progress to cvid which suggest common underlying genetic defects between sigad and cvid. this study was designed to find the prevalence of multiple cases in families of iranian patients with cvid or si...

fennel (foeniculum vulgare mill.) is widely cultivated for its edible, strongly-flavored leaves, fruits, seeds andmedicinal uses. as the wild and cultivated plants are influenced by environmental stresses, the effects of salt (25, 50 and 75 mm nacl), nitrogen and iron deficiency (0 n, 0.5 n of hoagland’s solution, 0 fe and 0.5 fe ofhoagland’s solution), 2°c cold (2, 3 and 4 h) and drought (3, 5...

Plasminogen activator inhibitor type 1 (PAI-1) is an important component of the coagulation system that down-regulates fibrinolysis in the circulation. Reduced PAI-1 levels may result in increased fibrinolysis and an associated bleeding diathesis. Clear documentation of PAI-1 deficiency as a cause of a bleeding disorder has been rare. PAI-1 was initially identified in the 1980s, and the first r...

The solutions of fluid-structure interaction problems, using displacement-based finite element formulations for acoustic fluids, may contain spurious non-zero frequencies. To remove this deficiency, we present here a new formulation based on a three-field discretization using displacements, pressure and a “vorticity moment” as variables with an appropriate treatment of the boundary conditions. ...
