the objective of this study was to investigate the relationship among body weight and fat-tail measurements with fat-tail weight by using multiple regression and principal component analysis. the eleven characters includes, body weight, fat-tail length, fat-tail circumference, width and diameters in 3 position of upper, middle and lower before the slaughter, and also fat-tail weight after the s...

The literature on gender peer effects documents that exposure to opposite gender peers can lead to higher academic performances for boys but lower outcomes, especially in math, for girls. This result can be explained by two distinct exposure effects. One is inside-class time exposure (e.g. boy peers are disruptive and lower the quality of student-teacher interactions) and the other is outside-c...

Banks are growing ever larger compared to their national economies. We show that increases in relative bank size (measured as a bank’s liabilities divided by national GDP) are linked to banks displaying higher tail risk. This effect is not entirely due to risk channels that disproportionately expose relatively large banks to systematic tail risks, sovereign risks, or banking crises. Instead, we...

1. The main site was at Dave and Busters in Columbus, Ohio. 2. We used a satellite site in the Cleveland, Ohio area at Progressive Insurance where there was a group in a conference room. We also had a few individuals attending via the web at other locations. 3. Frank Bereznay presented 2 papers from our main site. 4. Presenters Keith Tidball and Lori Zaremba from Progressive tag-teamed from 2 l...

background: the lori-bakhtiari sheep breed is one of the most common native breed in the south-western parts of iran. the peri-parturition period (2 weeks before to, 2 weeks after parturition), is generally of critical importance regarding the health, production and profitability of the ewes. objectives: this study was carried out to compare the serum concentrations of glucose, non-esterified f...

the archaeological evidence suggests that iran has been one of the first origins of sheep domestication in the world. this study aims to investigate the genetic diversity of indigenous iranian sheep breeds using mitochondrial dna (mtdna) and to explore the evolutionary history of sheep domestication in iran. single nucleotide polymorphism (snp) markers in the control region of mtdna were used t...

Tail-tip clipping is a common technique for collecting tissue samples from amphibian larvae and adults. Surprisingly, studies of this invasive sampling procedure or of natural tail clipping--i.e., bites inflicted by predators including conspecifics--on the performance and fitness of aquatic larval stages of urodeles are scarce. We conducted two studies in which we assessed the effects of poster...

Self-amputation (autotomy) of the tail is essential for the survival of many lizards. Accordingly, it has garnered the attention of scientists for more than 200 years. Several factors can influence the release of the tail, such as the size, sex, and age of the lizard; type of predator; ecology; and evolutionary history of the lineage. Once lost, the tail will writhe for seconds to minutes, and ...
