in order to investigate effects of addition of salvia mirzayanii essence and comparison with antibiotic an experiment was conducted as dietary a completely of the randomized design with 5 treatments, and 5 replicates with 12 chickens per replicate for 42 days with treatments control, virginiamycin antibiotic 10% (100 ppm) and three levels of s. mirzayanii essence (200, 400 and 600 ppm). weight ...

The peak SAR values of two-element array antennas for mobile handsets in the vicinity of a spherical phantom of a human head are evaluated numerically as a function of the distance between the array antenna and the head phantom when the two elements of a two-element array antenna are either co-phase voltage-fed or reverse-phase voltage-fed. It is found that relation between the worst case of th...

extraction of nickel and its co-extraction with copper from ammoniacal media into emulsion liquid membrane systems (elms) was investigated using lix 84i as the carrier. measurement of the solute stripped in the internal phase of emulsion opened a new dimension in the study of the elm extraction processes. the effect of operating parameters such as feed ph, initial feed concentration, and treat ...

The trial was conducted to evaluate the effect of different levels of dried sweet orange (Citrus sinensis) peel on growth performance in broilers. A total of 400 male broiler chicks (Ross-308) were randomly allocated to treatments varying in supplemental DSOP. The dietary groups consisted of five diets fed for 42 days: control diet without feed additive, diet containing 1.5 % feed additive only...

This experiment was conducted to determine the chemical composition and gross energy of poultry by product meal (PBPM) and the effects of different levels of inclusion of poultry by product meal on broiler chicken performance, serum uric acid and carcass characteristics. Three samples of PBPM produced in Ardabil province located in northwest of Iran, were provided during one month sampling peri...

mobile carrier properties of two schiff base ligands, named bis(2-hydroxypropiophenone)-1,2-propanediimine (n2o2) and bis(1'-hydroxy-2'-acetonaphthone)-2,2'-diiminodiethylamine (n3o2), dissolved in dichloromethane for the extraction of copper(ii) ions from an ammonium buffer feed phase into a nitric acid solution (receiving phase) were investigated and compared. the parameters influencing the t...

We compared weight gain, feed disappearance, coughing prevalence, and lung lesion scores among pigs vaccinated against Mycoplasma hyopneumoniae (treatments I and 2) and nonvaccinated controls. Pigs in both vaccinated treatment groups gained significantly more weight (0.14 Ib per day, P < .05) during the finishing phase when grow-finish data were pooled and compared to the control group. Pigs in...

Biofouling is still a major challenge in the application of nanofiltration and reverse osmosis membranes. Here we present a platform approach for environmentally friendly biofouling control using a combination of a hydrogel-coated feed spacer and two-phase flow cleaning. Neutral (polyHEMA-co-PEG10MA), cationic (polyDMAEMA) and anionic (polySPMA) hydrogels have been successfully grafted onto pol...
