abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
The present study was performed to assess the fertility of frozen-thawed dog semen prepared by freezing with 6% glycerol and thawing at 70 degrees C for 8 sec, and to evaluate the least number of post-thaw spermatozoa necessary to achieve pregnancy by intrauterine or intratubal artificial insemination. It was found that the pregnancy rate of intrauterine artificial insemination was 100% using 6...
The importance of measuring accurately and precisely the concentration of spermatozoa in semen is increasing as artificial insemination becomes widely practiced in veterinary medicine. This study tested the precision of the Neubauer hemocytometer with canine spermatozoa of varying concentrations within and between operators of different experience levels (Figure 1). We calculated the standard d...
During the last decade, an increasingly important technology in optimizing the production system has been the widespread adoption of artificial insemination (AI). The benefits of AI include decreased production costs, increased rate of genetic improvement, reduced disease transfer, and a more uniform and improved product at the packing plant. With appropriate timing and management, fertility ca...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Mares can be artificially inseminated with chilled or frozen semen to increase the revenue from their offspring. Embryo transfer can be used to produce more than one foal from a single mare per season. Recent advances in using equine follicle-stimulating hormone to induce superovulation in mares have stimulated research on preserving equine embryos. Equine embryos are usually collected on day 7...
BACKGROUND Insemination with donor sperm is an option for couples for whom in vitro fertilisation (IVF) or intra-cytoplasmic sperm injection (ICSI) has been unsuccessful, couples with azoospermia and for single women or same sex couples. Insemination of sperm can be done via cervical (CI) or intra-uterine (IUI) routes. IUI has been considered potentially more effective than CI as the sperm bypa...
BACKGROUND Artificial insemination (intrauterine insemination by husband or artificial insemination by husband) is often tried as first treatment for couples with unexplained infertility. Pertubation has previously proved to increase the chance of achieving pregnancy for these couples. The effect of pertubation on fertility can be mechanical as well as anti-inflammatory by using a substance tha...
