this study was conducted to investigate the effects of using gracilariopsis persica in layer diet on performance, egg quality and lipids of blood serum of layer hens. one-hundred hy-line w-36 hens were allocated to five dietary treatments (experimental diets containing 0, 5, 10, 15 and 20 percent seaweed) and five replicates and four birds in each for 12 week period (23-34 week of age). the res...

Thin silicon nitride (Si3N4) films deposited using plasma-enhanced chemical deposition (PECVD) method have been used as metalinsulator-metal (MIM) capacitor dielectric for GaAs heterojunction bipolar transistor (HBT) technology. The characteristics of the films, which were deposited at 300C, were found to be dependent on how the PECVD film was deposited. A silicon nitride film deposited as a mu...

in this research, modification on the ultrafiltration (uf) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (fo) water treatment. two monomers, m-phenylenediamine (mpd) and trimesoyl chloride (tmc) with different concentrations of mpd (2.0% w/v and 1.0% w/v) were reacted with tmc (0.15% w/v) for interfacial polymerization (...

in this experimental work, by using the method of plasma-chemical etching, we have dealtwith the causes of the creation of a distorted layer on the surface of silicon wafers during mechanicalmachining processes, in addition, the elucidation of connections between the structure of this layer andcharacteristic parameters of the mechanical strength of these wafers have been studied. experimentalre...
