Not your usual superconductor Most superconductors have only one superconducting phase. Khim et al . measured the magnetic susceptibility of heavy fermion material CeRh 2 As to reveal presence two distinct phases, which emerges from other when an external field is applied (see Perspective by Pourret and Knebel). The researchers ascribe unusual properties its crystal structure, globally centrosy...

Dogs presented to the Small Animal Hospital of Veterinary Medicine, University of Tehran were included in the present study if spinal or intervertebral disc involvement was suspected. Clinical signs were recorded as well as general information of the patient such as age, breed and sex. Sixty dogs were examined radiographically and two standard orthogonal lateral and ventrodorsal projections wer...

The Davis growth model (DGM) simulates growth and body composition of beef cattle and predicts development of 4 fat depots. Model development and evaluation require quantitative data on fat weights, but sometimes it is necessary to use carcass data that are more commonly reported. Regression equations were developed based on published data to interconvert between carcass characteristics and kil...

The aim of this study was to determine the chemical composition of stem and compost of the button mushroom to estimate metabolizable energy (ME) and net energy of lactation (NEl) using gas production method and to determine the amount of dry matter disappearance (DMD) using in vitro technique. This study was conducted in a completely randomized design with three treatments o...

In this work, novel thin film composite membranes (TFCs) of poly (ether-6-block amide) (Pebax-1657) on a polyvinyl chloride (PVC) ultrafiltration membrane as support were prepared using inclined coating method for CO2 separation. Investigating the effects of top selective layer thickness formed by controlling the coating angle (15-60°) and polymer solution concentration (5-10 wt.%), ...

The effect of different nitrogen levels on plant growth, phenol content, antioxidant and Nitrate reductase )NR) activity of cucumber (Cucumis sativus cv. Super) inoculated with mycorrhiza­ was studied. A factorial experiment based on a completely randomized design (CRD) with 6 replicates was designed. Treatments were three levels of nitrogen (NO3-50, NO3-75 and NO...
