Abstract The objective of this study was to determine genetic parameter estimates for age at first calving (AFC) in Red Angus and Simmental heifers. ability a heifer calve earlier has implications on calf performance the heifer's successive re-breeding. Heifer pregnancy data were obtained from International Genetic Solutions, where females with exposure records included population. Females subs...

background and objectives: synthetic dyes are recalcitrant to degradation and toxic to different organisms. decolorization of textile wastewaters is one of the major concerns since last decades. physical-chemical treatments are very expensive and frequently producing large amounts of toxic wastes. biological treatments can be more convenient. in the present study, an attempt has been made for d...

During experiments on the effect of direct electric currents on red cells suspended in saline an unexpected phenomenon was observed. Normal red cells showed agglutination and lysis, but if the red cells had been sensitized by antibodies there was a marked difference in the degree of agglutination and lysis. Samples of red cells which had been treated with " blocking " Rhesus antibody (anti-D an...

External distraction using a rigid external distractor (RED) frame (RED frame II, KLS-Martin, Jacksonville, USA) is frequently used for maxillary distraction and reconstruction.[1-3] Airway management with the RED frame could be a greater risk of failed intubation/extubation. It could significantly interfere with ventilation with a face mask or intubation by direct laryngoscopy. However, anaest...
