An experiment was conducted to investigate the effect of zinc (Zn) supplementation and different concentrations of calcium (Ca) and phosphorus (P) in wheat-based diets on the performance, immune responses and bone parameters of broiler chickens. A randomized complete block design with factorial arrangement was used (three concentrations of Zn supplementation×two concentrations of dietary Ca-P),...

Acesta excavata (Fabricius, 1779) is a slow growing bivalve from the Limidae family and often found associated with cold-water coral reefs along European continental margin. Here we present compositional variability of frequently used proxy elemental ratios (Mg/Ca, Sr/Ca, Na/Ca) measured by laser-ablation mass spectrometry (LA-ICP-MS) compare it to in-situ recorded instrumental seawater paramet...

Freshly harvested tomato fruit (Solanum lycopersicum) were pre-treated with 0, 50, and 100 µM prohexadione-calcium (Pro-Ca) and then stored at 1 °C for 21 days to investigate the effect of Pro-Ca treatment on electrolyte leakage (EL), malondialdehyde (MDA), proline and total phenols contents, and activity of phenylalanine ammonia-lyase (PAL) in relation to chilling injury (CI).Treatment with Pr...

This research work has been carried out to study the effect of different Ca contents (0.5, 1.0, 1.5, 2.0 and 3.0) on the microstructure and porosity content of ZK60 alloys. The samples were examined by using optical and scanning electron microscopy (SEM) to evaluate the modification efficiency of the alloy with different Ca concentrations. The cast specimens were modified, homogenized and extru...

background and objectives: studies have shown that patients awaiting coronary angiography (ca) are often anxious. high level of anxiety can lead to physical and psychological stress with adverse effects on organs, es­pecially heart. there is limited information on state and trait anxiety level in these patients in the literature. this study was thus designed to investigate the level of these tw...
