Enterococci from pigs in Denmark, Spain, and Sweden were examined for susceptibility to antimicrobial agents and copper and the presence of selected resistance genes. The greatest levels of resistance were found among isolates from Spain and Denmark compared to those from Sweden, which corresponds to the amounts of antimicrobial agents used in food animal production in those countries. Similar ...

Microfiltration can clarify pomegranate juice; however, fouling is a limiting phenomenon in the process. In current work ultrasound was applied above and below the membrane surface to reduce fouling after removing temperature effect. A hydrophilic mixed cellulose ester membrane with pore size of 0.45 μm was used in lab scale flat sheet module. Membrane module was placed above and below the ultr...

This study aimed to determine the effects of replacement fish meal by different levels of gammarus meal on growth performance and body composition of juvenile Siberian sturgeon (Acipenser baerii). We distributed 245 Siberian sturgeon juveniles (initial body weight: 14.24±0.15 g) in five treatments and three replications. The experimental diets were replaced by 10%, 20%, 30%, and 40% gammarus me...

This study aimed to determine the fat requirement and effect of dietary fat levels on growth and body composition indices of hybrid Asp (Leuciscus aspius ♀) × Caspian Kutum (Rutilus frisii ♂). For this purpose, 252 fish with an average weight of 29.3 ± 5.8 g were introduced in a completely randomized design with six treatments each with triplicate groups. After two weeks of adaptation, fish wer...

The recovery of high-quality, valuable end products from cheese whey is a very important industrial process. The aim of this study is to improve the recovered protein content of concentrate stream in cheese whey. The experiments were conducted by using ceramic ultrafiltration (UF) membrane followed by diafiltration (DF) process with a 15kDa molecular weight cut-off (MWCO). The volume concentrat...

A novel type of circularly polarized broadband antenna consisting of a modified circular wideslot aperture and an L-shaped feed probe is introduced. The modified circular wide-slot is partially covered to generate circular polarization with broadband characteristics in the axial ratio. Variations in both the axial ratio and the S11 characteristics of the device are investigated and radiation pa...

We describe the pitfalls encountered in deducing from classical double radio source observables (luminosity, spectral index, redshift and linear size) the essential nature of how these objects evolve. We discuss the key role played by hotspots in governing the energy distribution of the lobes they feed, and subsequent spectral evolution. We present images obtained using the new 74MHz receivers ...

Short term in vitro incubations were used to evaluate the effect of fumaric acid bentonite coupled addition on rumen fermentation effeciency. Ruminal contents from five steers were used for preparation of inoculums of mixed rumen microorganisms that were used in generatation of three treatment systems, negative control, fumaric acid treated, and fumaric acid – bentonite coupled treated. The fer...
