Rumen degradation kinetics and effective degradability of individual amino acids, total analysed amino acids (TAA) and crude protein (CP) of soybean meal were measured on four rumen-cannulated wethers using the nylon bag technique. Microbial contamination of the incubated residues was corrected using a continuous 15N intraruminal infusion and isolated solid associated bacteria as a reference sa...

To determine prececal starch digestibili-ty and estimate glucose uptake from the digestion of 4 forms of barley in the small intestine, 4 mature cecally fistulated geldings (449 ± 41 kg BW) fed a 62:38 (wt/wt) meadow hay:concentrate diet at 1.7 kg DM/100 kg BW were included in a 4 × 4 Latin square design experiment. During each period, horses received 80% DM of their concentrate as 1 of the 4 f...

industrial processes release a range of gaseous and particulate pollutants containing heavy metals into the air. lack of enough attention to the design, installation, repair and maintenance of gas and dust filtration systems in industries, is one of reasons of increasing the emissions of these pollutants. hereon, the steel making processes is one of emission sources of heavy metals. according t...

introduction feed shortage is the most important characteristic of iranian animal industry. increased costs of livestock production have caused the iranian producers to reduce feed costs mainly by inclusion low quality crop residues into ruminants diets. it is estimated that around 20 million tons wheat straw produced in iran every year. both the digestibility and crude protein content of wheat...

Colorectal endoscopic submucosal dissection (ESD) is considered to be a difficult procedure that has a high risk of adverse events [1]. Endoscopic procedures should be performed under direct visualization, but it is often difficult to maintain appropriate visualization during submucosal dissection. A traction method using an endoclip attached to a string was developed in order to maintain good ...

In the present paper comparison of dimensional accuracy and form errors FFF (Fused Filament Fabrication) 3D printed spur gears obtained in two different polymeric materials (PLA Nylon-PA6) is presented. Two types were designed printed, having module teeth number. First, gear modelling process The printing parameters defined for both materials. Then, measuring processes described. Using method s...

The aim of this study is to enhance the tensile and flexural strength polyamide (nylon 6, 6) by incorporation glass fibre. Nylon has high elasticity, strength, toughness maintain mechanical properties at elevated temperatures. method employed for enhancement reinforcement Glass fibre most extensively used material. It a lightweight, extremely solid, durable, low cost material that moderafly sti...

Banana fiber (BaF)-filled composites based on high density polyethylene (HDPE)/Nylon-6 blends were prepared via a two-step extrusion method. Maleic anhydride grafted styrene/ethylene-butylene/styrene triblock polymer (SEBS-g-MA) and maleic anhydride grafted polyethylene (PE-g-MA) were used to enhance impact performance and interfacial bonding between BaF and the resins. Mechanical, crystallizat...
