The susceptibility of geese of different genotypes and sexes to force-feeding, some plasma biochemical parameters (thyroid hormones, cholesterol, retinoids, total protein and albumin) of force-fed geese, and the relationship between force-feeding, fat storage and the above-mentioned parameters were studied. Sixty (30 male and 30 female) geese of three(More)
In this in vitro study the effects of copper sulphate on the motility, morphology and structural integrity of rabbit spermatozoa were investigated. The spermatozoa motility was evaluated by CASA method and Annexin analysis was used for detection of structural changes. For analysis of morphology samples of rabbit semen were fixed with Hancock's solution and(More)
Blood pH, total plasma carotene, plasma vitamin A fractions and some plasma proteins were determined in newborn calves (n = 38) and their dams. Calves were assigned to one of two groups according to their blood pH immediately after birth: group 1 (normal) with pH above 7.2 (n = 27) and group 2 (slightly acidotic) with pH 7.0 to 7.2 (n = 11). The difference(More)
In this work-in-progress paper, we present REXplorer, a mobile, location and gesture recognition based spell-casting multiplayer game for tourists. Launching in late summer 2006, this serious game will be installed as a permanent pervasive entertainment service on site the medieval city core of Germany's best preserved historic city, Regensburg. In(More)
In this study the effect of in vitro culture of bovine spermatozoa with nickel (NiCl(2)) on spermatozoa motility and membrane changes was analyzed. The spermatozoa motility significantly decreased after 120 min of culture at the concentration of 1000 μM Ni ml(-1) (P < 0.05) and after 240 min of culture at the concentration of 500 and 1000 μM Ni ml(-1) (P <(More)
The purpose of this in vitro study was to determine the effect of copper (Cu) on the motility and viability of spermatozoa in the presence of different culture media. Specifically, we examined the dose- and time-dependent effect of copper ions (Cu(2+)) on the motility and viability of spermatozoa during different time periods (Time 0 h, 1 h, 24 h). The(More)
Oxidative stress is a state related to increased cellular damage caused by oxygen and oxygen-derived free radicals known as reactive oxygen species (ROS). It is a serious condition, as ROS and their metabolites attack DNA, lipids and proteins, alter enzymatic systems and cell signalling pathways, producing irreparable alterations, cell death and necrosis.(More)
The impact of sensorimotor transformations with graphical input devices is surveyed with regard to action control. Recent evidence lets us assume that the distal action effect (the moving cursor) rather than the proximal action effect (the moving hand) determines the efficiency of tool use. In Experiment 1 different gains were explored with a touchpad and a(More)
Tool use often challenges the human motor system, especially when these tools require sensorimotor transformations. We report an experiment using a digitizer tablet, in which different gains are introduced between the hand movement (proximal effect) and the intended action effect presented on a display (distal effect). The question is how one’s own(More)
