Salinity is a major concern in several ecosystems and has significant impact on global agriculture. To increase the sustainability of horticultural food systems, better management usage saline water soils need to be supported by knowledge crop-specific responses tolerable levels salinity. The aim this work was study effects mild salinity morphological growth development, leaf color, mineral com...

Heavy metals may exacerbate metabolic syndrome (MS) but abnormal serum concentrations of bioelements may also co-exist with MS. The primary aim of the study was to assess the relationship of blood heavy metal and bioelement concentrations and MS, in men aged 50-75 years. Heavy metals-lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As), tungsten (W), Macroelements-magnesium (Mg) and calcium (Ca)...

The article describes the dynamics of changes in blood concentrations of the active substances present in the solution after its infusion to healthy cows in comparison to NaCI solution as well as the response of paretic cows to treatment with the new complex solution. Cows received a dose of 400 ml of A1 solution (containing 8.4 g of Ca2+) intravenously. In healthy cows the average calcium conc...

BACKGROUND Many studies demonstrate that the elderly consume a nutritionally inadequate diet that includes deficiencies in macro- and microelements; iron and zinc being significant examples of the former. OBJECTIVES To assess the adequacy of dietary iron and zinc intakes in the elderly. MATERIAL AND METHODS The study was conducted on n = 102 elderly persons, participating in the PolSenior P...

BACKGROUND A total of 150 bread wheat genotypes representing 121 Indian and 29 Turkish origin were screened for nutrient concentrations and grain protein content. Elemental and grain protein composition were studied by Inductively Coupled Plasma-Atomic Emission Spectrophotometer and LECO analyser, respectively. The study was performed to determine the variability in nutrient concentrations pres...

BACKGROUND Legumes are a good source of protein, and are also abundant in carbohydrates, B-group vita-mins, dietary fibre and mineral compounds. MATERIAL AND METHODS This work evaluates the retention of ash, eleven minerals and two heavy metals in products obtained from two common bean cultivars harvested before reaching full maturity, with a dry matter content of about 40%. Analyses were con...

An accurate evaluation of the non-linear behavior of masonry structural elements in existing buildings still represents a complex issue that rigorously requires non-linear finite element strategies difficult to apply to real large structures. Nevertheless, for the static and seismic assessment of existing structures, involving the contribution of masonry materials, engineers need reliable and e...

nowadays, organic fertilizers play an important role in agriculture. they are progressively substituting chemical fertilizers to prevent their harmful impact on human health and the environment. they provide high yield, better quality products and a shorter period of harvesting crops. in this study, the mineral elements: primary macronutrient (n, po3- and k+), secondary macronutrient: (ca2+, mg...

a greenhouse experiment was carried out to evaluate the effects of salinity stress on growth and macroelements contents of two olive varieties under hydroponic conditions. in the research, one-year old saplings of two olive varieties, ‘zard’ and ‘mission’, were subjected to different salinity levels induced by nacl including 0, 4, 8, 12 and 16 dsm-1 for 5 months. based on the results, total dry...

This work is concerned with the derivation of adaptive methods for discontinuous Galerkin approximations of linear fourth order elliptic and parabolic partial differential equations. Adaptive methods are usually based on a posteriori error estimates. To this end, a new residual-based a posteriori error estimator for discontinuous Galerkin approximations to the biharmonic equation with essential...
