A bull is a graph with five vertices r, y, x, z, s and five edges ry, yx, yz, xz, zs. A graph G is bull-reducible if no vertex of G lies in two bulls. We prove that every bull-reducible Berge graph G that contains no antihole is weakly chordal, or has a homogeneous set, or is transitively orientable. This yields a fast polynomial time algorithm to color exactly the vertices of such a graph.

Bull gore injuries (cornadas) are the most frequent injuries caused by bulls during bull-related events. Blunt trauma caused by being struck by the bull’s horns and/or head (known as varetazos) usually causes less serious injuries. We present the case of a patient who received blunt trauma from a bull horn, that caused diaphragm rupture and right hepatic avulsion requiring right hepatectomy, ve...

Symptom-bearing plant material of the Lilliaceae, Ashodelus macrocarpus, was collected July 1991 in Greece. After surface sterilization, small segments of stem, leaf and fruit were plated on Potato Dextrose Agar (PDA, Difco) plates and incubated for 2 days at 26°C. Pure cultures could be obtained from the plates by one additional transfer to PDA plates. The culture was maintained on PDAslants a...

background: consumption of energy drinks has become widespread among athletes. the effectiveness of red bull and hype energy drinks on selected indices of maximal cardiorespiratory fitness and blood lactate levels in male athletes was examined in this study. methods: ten male student athletes (age: 22.4 ± 2.1 years, height: 180.8 ± 7.7 cm, weight: 74.2 ± 8.5 kg) performed three randomized maxim...

There are many factors influencing the energy consumption of buildings in complex working conditions. In order to study residential with nearly zero cold and arid regions northwest China, such as roof heat transfer coefficient (KR), exterior wall (KE), ground (KG), window (KEW), north ratio (WWRN), south (WWRS), east west (WWRWE), building orientation (BO), ventilation times (VT) taken this pap...

Bull trout Salvelinus confluentus are a species of char that have been intensively studied since they were listed as threatened under the U. S. Endangered Species Act in 1998. Much of the research on bull trout has involved the use of radio telemetry to monitor the movements of this highly mobile species. This project was initiated to compile information on completed and ongoing radio telemetry...

To preserve Jeju black cattle (JBC; endangered native Korean cattle), a pair of cattle, namely a post-death cloned JBC bull and cow, were produced by somatic cell nuclear transfer (SCNT) in a previous study. In the present study, we examined the in vitro fertilization and reproductive potentials of these post-death cloned animals. Sperm motility, in vitro fertilization and developmental capacit...

—An understanding of habitat relationships for bull trout Salvelinus confluentus remains an important component for identifying future restoration, management, and recovery efforts. We examined past efforts through a comprehensive synthesis of peer-reviewed articles evaluating bull trout habitat relationships, and we used field data within classification tree analysis (CTA) to improve our under...

The "energy drink" Red Bull and the "sports drink" Gatorade are often marketed to athletes, with claims that they cause performance gains. However, both are high in sugars, and also consumed by non-athletes. Few studies have addressed the effects of these drinks or their biologically active components in rodent exercise models. We used three experiments to test effects on both voluntary exercis...
