in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants the concept of synchronization energy and protein was first by jhonson, implying that maximum microbial protein synthesis could be achieved by matching the rate of organic matter and protein degradation. synchronization of rumen available...
Small-scale dairy farming in Bangladesh is constrained mostly due to acute shortage, high price and seasonal fluctuation of energy and protein supplements. Poor economic conditions of dairy farmers do not allow them to purchase adequate conventional energy and protein supplements. Locally available non-conventional energy and protein sources can be used as alternatives, cheaper than conventiona...
Background: The important risk factors in obesity are related to unhealthy nutritional habits. The aim of this study was to estimate and compare the macro- and micro-nutrients’ intake in breakfast and midmorning snacks. Methods: This cross-sectional study was conducted among 569 students (12-16 years) by the multistage cluster sampling method. The demographic data were gathered by interview. A...
abstract coontail (ceratophyllum demersum) and watermilfoil (myriophyllum spicatum) are current submersed weeds in many fresh waters of iran. the excessive growth of these plants causes the reduction in utilization of water resources and making some ecological and economical damages in these areas. the aim of this study was to determine the response of two submerged aquatic weeds of coontail an...
consuming a healthy diet throughout the lifecourse helps prevent malnutrition in all its forms as well as a range of non-communicable diseases (ncds) and conditions. but the increased production of processed food, rapid urbanization and changing lifestyles have led to a shift in dietary patterns. people are now consuming more foods high in energy, fats, free sugars or salt/sodium, and many do n...
Obesity is the result of an imbalance between energy intake and energy expenditure. Under most circumstances, the increased availability of nutrients is tightly coupled with nutrient-sensing mechanisms that in turn activate appropriate behavioral and metabolic responses. The latter responses include decreases in food intake and the production of endogenous nutrients and increased expenditure of...
