The objective of this study was to determine if factors associated with the biostimulatory effect of bulls alter breeding performance of primiparous, suckled beef cows using a progestin-based estrous synchronization protocol. We tested the hypotheses that the estrous synchronization response and AI pregnancy rates differ among cows exposed to bulls, continuously exposed to bull urine, and expos...

When culturing the pileitrama of young fruit bodies of the two mycoparasitic agarics, Asterophora lycoperdoides (Bull.: Fr.) Ditmar and A. parasitica (Bull.: Fr.) Singer, two tremelloid yeasts were detected (Laaser et al., 1988, 1989; Prillinger, 1987a). The term tremelloid was suggested by Oberwinkler (Laaser et al., 1988; Oberwinkler pers. comm.) for budding yeasts having a cup-shaped parenth...

We conducted this study to evaluate the prevalence of daytime sleepiness and evening chronotype, and to assess the extent to which both are associated with the use of caffeinated stimulants among 3,000 Thai college students. Demographic and behavioral characteristics were collected using a self-administered questionnaire. The Epworth Sleepiness Scale and the Horne and Ostberg Morningness-Evenin...

Bull rays (Pteromylaeus bovinus) and Dolphinfish (Coryphaena hippurus and Coryphaena equiselis) were collected in Olhão (south of Portugal). These animals hosted multiple parasites, namely Caligus spp., and underwent a variety of treatments to remove them. Of all treatments tested, hydrogen peroxide showed the best results, although only concentrations above 100 ppm were effective in parasite r...

Theory predicts that attribution bias creates overconfident traders and thus causes excessive trading in the market. This paper tests this prediction by comparing the trading behavior of individual investors in different market conditions. In a bull market, investors suffer more from attribution bias and therefore should be more overconfident and trade more excessively. Using the trading record...
