Straight spinning cosmic strings in Brans-Dicke gravity

It is presented an exact solution of straight spinning cosmic strings in Brans-Dicke theory of gravitation. The possibility of the existence of closed timelike curves around these cosmic strings is analyzed. Furthermore, the stability about the formation of the topological defect discussed here is checked. It is shown the existence of a suitable choice for the integration constants in which closed timelike curves are not allowed. We also verify if it is possible that the obtained spacetime can be the source that describes the observed rotational curves in some galaxies.Comment: 13 pages, 1 figur

Athletes’ Expectations About Sport-Injury Rehabilitation: A Cross-Cultural Study

Context: Athletes enter injury rehabilitation with certain expectations about the recovery process, outcomes, and the professional providing treatment. Their expectations influence the effectiveness of the assistance received and affect the overall rehabilitation process. Expectations may vary depending on numerous factors such as sport experience, gender, sport-type and cultural background. Unfortunately, limited information is available on athletes’ expectations about sport injury rehabilitation. Objective: To examine possible differences in athletes’ expectations about sport injury rehabilitation based on their country of residence and type of sport (physical contact versus non-physical contact). Design: A cross-sectional design. Setting: Recreational, collegiate, and professional athletes from the United States (US), United Kingdom (UK) and Finland were surveyed. Participants: Of the 1209 athletes ranging from 12 to 80 years of age (Mage = 23.46 ± 7.91), of which 529 US [80%], 253 UK [86%], and 199 Finnish [82%] provided details of their geographical location, were included in the final analyses. Main Outcome Measures: The Expectations about Athletic Training (EAAT) questionnaire was used to determine athletes’ expectations about personal commitment, facilitative conditions, and the expertise of the sports medicine professional (Clement et al., 2012). Results: 3x2 MANCOVA revealed significant main effects for country (p = .0001, ηp2 = .055) and sport type (p = .0001, ηp2 = .023). Specifically, US athletes were found to have higher expectations of personal commitment and facilitative conditions than their UK and Finnish counterparts. Athletes participating in physical contact sports had higher expectations of facilitative conditions and the expertise of the sports medicine professional (SMP) as compared to athletes participating in non-physical contact sports. Conclusions: SMPs, especially those in the US, should consider the sport and environment when providing services. In addition, SMPs need to highlight and demonstrate their expertise durin

The purpose of this study was to determine the performance of Kampung Unggul Balitnak (KUB) chicken fed palm mud fermented feed. Completely Randomized Design (CRD) was used in this study, with five treatments (5) and four replications (4). Each replication was placed 6 chickens aged 7 days. The results showed that the use of fermented palm sludge had no significant effect on feed consumption, body weight gain, and feed conversion value of KUB chickens. The use of fermented palm oil sludge in feed gives a good value to the performance of Kampung Unggul Balitnak (KUB) chickens
