Many key components of implantable medical devices are made from polymeric materials. The functions of these materials include structural support, electrical insulation, protection of other materials from the environment of the body, and biocompatibility, as well as other things such as delivery of a therapeutic drug. In such roles, the stability and integrity of the polymer, over what can be a...

Effects of Adding Different Levels Date Pulp on the Aerobic Stability, Degradability Parametrs and Nutritional Value Alfalfa Silage using Gas Production

this study was conducted in two separate experiments. four rumen-cannulated sheep were allocated in the first experiment to evaluate date by-product (dbp) and date seed (ds) nutrients degradation in rumen. in experiment two eighteen fattening lambs were allocated in three different treatments (6 animals/treatment) to evaluate dbp effects on animal performance and nutrients’ digestibility. three...

samples of salvia leriifolia were collected from khorasan mountains in different growing stages. chemical composition, rumen degradability characteristics of dry matter (dm), crude protein (cp) and neutral detergent fiber (ndf) of salvia leriifolia whole plant (stem and leaves) in different flowering stages and plant leaves in comparison with alfalfa hay and triticale straw were measured using ...

Eighteen structurally varied amines were subjected to harsh oxidative conditions, and their stability was assessed seen in the context of biological thermal stability. Steric effects play a large role stabilization under presence carbon dioxide plays vital degradation pathway ethanolamine (MEA). Tertiary are generally very stable, known not form carbamates any extent. Many steric stabilization,...

during the past two decades, the use of bioplastics as an alternative to regular plastics has received much attention in many different industries. the mechanical and degradable properties of bioplastic are important for their utilization. in this research cellulose of wheat straw and glycerol were mixed by different weight ratios and then reinforced by using date palm fibers. to prepare the bi...
