ABSTRACT The application of on-line monitoring system for recording main welding parameters during electric arc stud welding process at different electric arc stability changes is described in this paper. In the first part of the paper, the basics of electric arc stud welding process, and equipment for stud welding and process monitoring used in experimental part is described. In the second par...

The chemosignals from mating male are found to be responsible for protecting his coital partner against pregnancy failure induced by strange male or food-deprivation. The stud male pheromone not only provides luteotrophic support in female of vulnerable condition but also exerts luteotrophic effect in pregnancy-blocked females by inducing pseudopregnancy. The luteotrophic stimulus rendered by s...

BACKGROUND Pregnancy rates with cooled equine semen can be unsatisfactory and show great variation. Information about first cycle pregnancy rates and pregnancy rates per cycle are often lacking from publicly available records. This retrospective cohort study was performed to evaluate the fertility of the Norwegian Coldblooded trotter. The aim of the study was to compare the breeding results aft...

This research effort focuses on the evaluation of existing design standards for cold-formed steel stud walls and the development of retrofit wall systems. Full-scale wall systems are tested under uniform static pressure using a vacuum chamber. The resistance functions obtained are used to model the dynamic behavior of the walls and to predict performance under blast conditions. This paper focus...

When female voles were allowed contact with the stud male for only 1 h at the time of mating, 55% exhibited pregnancy failure when exposed to a strange male 48 h later. When females were made psuedopregnant by hormone treatment and vaginal stimulation (i.e. no stud male involved), 87% exhibited luteal failure when exposed to a strange male. It is suggested that the characteristics of the stud m...

Recently, Gandomi and Alavi proposed a meta-heuristic optimization algorithm, called Krill Herd (KH), for global optimization [Gandomi AH, Alavi AH. Krill Herd: A New Bio-Inspired Optimization Algorithm. Communications in Nonlinear Science and Numerical Simulation, 17(12), 4831–4845, 2012.]. This paper represents an optimization method to global optimization using a novel variant of KH. This me...

The block to pregnancy in newly mated female mice caused by the proximity of a strange male (`Bruce effect') occurs in a greater number of females when the male belongs to a different strain from the female (alien male) than when he belongs to the same strain (strange male) (Bruce, 1960; Parkes & Bruce, 1961). The difference between strains implies that the uniformity of odour or `spectrum of o...
