this study was conducted to determine the chemical composition and metabolizable energy of poultry by-product meal (pbpm) from two slaughterhouses in iran. samples were analyzed for dry matter, crude protein, ash, ether extract and gross energy. the amounts of calcium, phosphorus, sodium, potassium, magnesium, iron, manganese, copper and zinc were determined. the apparent metabolizable energy (...

the objective of the present study was to determine chemical composition and fatty acid profile of common kilka ,clupeonella cultriventris caspia, in the caspian sea. the chemical analysis revealed that the protein and lipid content of common kilka were 15.05 and 6.5% of the fresh weight, and total mufa, pufa and sfa were found to be 37.00, 32.89 and 29.03% respectively. palmitic acid (16:0) am...

BACKGROUND In the coming years, a nutraceutical food may provide both physical and mental benefits that are commonly attributed to the active components of the food. OBJECTIVE In this study, we determined the nutrient and mineral contents, sensory properties, and physical and chemical characteristics of ice creams manufactured using peach fibre at different concentrations (1 and 2%). METHOD...

Six BiOX1-xYx (X, Y = F, Cl, Br, and I) solid solutions have been systematically investigated by density functional theory calculations. BiOCl1-xBrx, BiOBr1-xIx, and BiOCl1-xIx solid solutions have very small bowing parameters; as such, some of their properties increase almost linearly with increasing x. For BiOF1-xYx solid solutions, the bowing parameters are very large and it is extremely dif...

Changes in the chemical composition of soil organic carbon (SOC) might strongly affect the global carbon cycle as it controls the SOC decomposition rate. Vegetation change associated with long-term land use changes is known to strongly impact the chemical composition of SOC; however, data on the impacts of vegetation change following disturbance events of short durations and succession that occ...

  Objective: In order to use natural compounds in controlling plant pests and diseases, many researchers in recent years have studied the antifungal effects of essential oils and plant extracts.  The purpose of this study was to investigate the chemical composition and antifungal effects of Echium khuzestanium and marubbium anisodan extract...

Cauda epididymal rat spermatozoa were isolated by flushing the excised epididymis and the plasma membrane was detached by a nitrogen cavitation treatment (500 psi, 10 minutes equilibration at 4 C). Membrane vesicles were recovered after sucrose gradient centrifugation. Portions of the sperm surface releasing the plasma membrane were assessed by light microscopy of fluoroscein isothiocyanate-suc...
