For many years reflector Impulse Radiating Antennas (IRAs) were built with four feed arms positioned at ±45° to the dominant polarization (usually vertical). However, recent experimental and numerical investigations have demonstrated improved gain and crosspol performance when the feed arms were positioned at ±30° to vertical. Despite these results, there has been a belief that one could obtain...

one experiment was conducted in order to evaluate four levels of macaroni waste including: 0, 10, 20 and 30 percentage in growing turkey feed in a completely randomized design (crd) with 120 local turkey including 3 replicates in 12 pens. during the experiment (3-8 weeks), turkeys received feed and water of free access. weight gain, feed consumption and feed efficiency were measured weekly. dif...

The aim of this study was to use PARACHEK Johne's Absorbed EIA-CSL, gamma interferon test IFN BOVIGAM-CSL , Mycobacterial Growth Indicator Tube MGIT, BACTEC 960 BECTON-DICKINSON, PCR with IS900 probe, to diagnose paratuberculosis in sheep from the Argentine North East (ANE) and compare the results with those of the comparative skin testing using bovine and avian PPD (B-PPD and A-PPD), agar gel ...

The effectiveness of a new design of electric strained wire fence (CSL fence) for managing rabbits is currently being assessed in a two year trial. It is being compared with a commercially available electric netting fence (Flexinet fence) and also with farmers' normal control methods. The study is taking place on commercial farms in Cornwall, England, where the fences are being erected to prote...

Chinese Sign Language (CSL) and are languages used in the mainland. As a dominant language, has great influence on all levels of CSL. CSL, as visual sign is fundamentally different from linguistic structure. Unlike English, Chinese, pictograph, This study explains detail characters CSL at lexical level, including many elements such "仿字fangzi" (form imitating characters), "书空shukong" (writing ai...

Introduction. Students’ satisfaction reflects the effectiveness of all aspects of education. Achieving clinical skill is a key process about medical education. For this reason it is necessary to build up a place similar to the hospital called Clinical Skill Lab (CSL). The aim of this study was to evaluate the medical students’ satisfaction from clinical Skill Lab of Tabriz for finding educatio...

We find an analogy between turbulence and the dynamics of the continuous spontaneous localization model (CSL) of the wave function. The use of a standard white noise in the localization process gives Richardson’s t law for the turbulent diffusion, while the introduction of an affine noise in the CSL allows us to obtain the intermittency corrections to this law. PACS: 05.40.Fb, 03.65.Bz, 02.50.E...

Extraction of microamounts of cesium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B-) in the presence of 2,3-naphtho-15-crown-5 (N15C5, L) has been investigated. The equilibrium data have been explained assuming that the complexes HL+, HL+2, CsL+ and CsL+2 are extracted into the organic phase. The values of extraction and stability constants of the species in nitrobenzene satu...
