    2014-01-01

    Full Text Available Introduction. Medical students experience significant psychological stress and are therefore at higher risk of using sedatives. There are currently no studies describing the prevalence of sedative drug use among medical students in Saudi Arabia. The aim of this study was to evaluate the prevalence and factors associated with sedative drug use among medical students in Saudi Arabia. Materials and Methods. A cross-sectional convenience sampling study gathered data by anonymous questionnaire from students enrolled at the King Saud University College of Medicine in 2011. The questionnaires collected data regarding social and demographic variables, sleep patterns, and the use of stimulant and sedative drugs since enrollment. Sedatives were defined as any pharmaceutical preparations that induce sleep. Results and Discussion. Of the 729 students who returned questionnaires, 17.0% reported sedative drug use at some time since enrollment. Higher academic year, lower grade point average, regular exercise, fewer hours of sleep per day, poorer quality of sleep, and the presence of sleeping disorders were found to be significantly associated with sedative drug use. Conclusions. Further study is required to increase our understanding of sedative drug use patterns in this relatively high-risk group, as such understanding will help in the development of early intervention programs.

    Fertility levels and their determinants in Saudi Arabia have not been studied sufficiently for formulating family policy, although some attention has been paid to rapid fertility transitions in the context of socioeconomic and cultural change. This study focused on the fertility of a particular occupational category in the Kingdom of Saudi Arabia to assess determinants of fertility, measured as the number of children. The sample was drawn from the King Saud University staff - ever-married Saudi Arabian women. Results found that proximate factors (age, age at first marriage, intended number of children, length of marriage and contraceptive use) were significant in predicting fertility behaviour, whereas geographic, social and economic factors were insignificant. Thus, the fertility behaviour of this occupational group seems unique. This might be due to the special characteristics and lifestyle of this particular occupational group. The effect of the intended number of children on the actual number signified the fertility behaviour of this group of women. This, expectedly, should improve the influence of social and economic factors on fertility behaviour, in the future. Thus, advocates, policies and programmes (population and public health) at the societal and familial levels, should consider the demographic change in the social and economic context.

    Tobacco smoking is the preventable health issue worldwide. The harmful consequences of tobacco smoking and exposure to second-hand tobacco smoke are well documented. The aim of this study is to compares the prevalence of smoking among students, faculty and staff and examines their interest to quit. Study also determines the difference on perceptions of smoking and non-smoking students, faculty and staff with regard to implementation of a smoke-free policy. A cross-sectional survey was administered to one of the largest universities in Riyadh, Saudi Arabia during the academic year of 2013. A Likert scale was used on questionnaires towards attitude to smoking and smoking free policy. The Chi squared test was used to determine the difference of support on completely smoke free campus for smokers and non-smokers. Smoking rates were highest among staff members (36.8 %) followed by students (11.2 %) and faculty (6.4 %). About half of the smokers (53.7 %) within the university attempted to quit smoking. Students (OR 3.10, 95 % CI 1.00-9.60) and faculty (OR 4.06, 95 % CI 1.16-14.18) were more likely to make quit smoking than staff members. Majority of the respondents (89.6 %) were supportive of a smoking--free policy and indicated that should be strictly enforced especially into public places. Results also showed that smokers were more likely to support a smoke-free policy if there are no fines or penalties. These baseline findings will provide information among administrators in formulating and carrying out a total smoke free policy. Although the majority of people within the King Saud University demonstrate a high support for a smoke-free policy, administrators should consider difference between smokers and non-smokers attitudes when implementing such a policy.

    A study was designed to determine the red cell values (hemoglobin and hematocrit) of neonates born in the high altitude of Abha and to compare these values with known values of other lowland areas of Saudi Arabia. From the cord blood of 587 normal, appropriate for gestational age and term infants born in 1993 in Abha Maternity Hospital, the ranges of Hb and Hct were 130 to 240 g/L and 0.24 to 0.79 L/L respectively. The mean Hb was 187 g/L. There was no significant difference between the male and female values. Also, 17% of the infants in this study were polycythemic, while no polycythemia was recorded in these lowland areas and only 2% to 4% in the general global newborn population. It was therefore revealed that Abha newborns had higher red cell values at the birth when compared to other newborns in the low altitude areas of Riyadh and Jeddah (P<0.001). We postulate that high altitude (2700 meters above sea level) of Abha, and therefore its relative hypoxia, has induced high red cell values in infants born in the city. The phenomenon therefore warrants the adoption of higher red cell reference values and not necessarily those already documented in other Saudi new born populations. (author)

    The purpose of the study was to assess the relationship between students' perception of course/block coordinators performance and attributes with students' assessment scores in respective courses. This retrospective data based study was conducted at the College of Medicine, King Saud bin Abdulaziz University of Health Sciences (KSAU-HS). It was started in March 2013 and completed in June 2013 after the graduation of the fourth cohort. Exam score of 3(rd) and 4(th) cohort of students from the courses taught in the last two years of medical school were correlated with faculty and block evaluation done by the students. Scores from mid-block MCQs, portfolio scores, OSCEs and end-of-block MCQs were obtained. The Mean scores of all the assessments for all five blocks were not significantly different for both batches. There was significant difference between block coordinators for students' score on portfolio, midterm exam and the final written exam. The students' Score in OSCE had significantly strong correlation with quality of station monitors, coverage of content and flow between stations. Student's perception of the commitment and motivation of the coordinator was strongly correlated with block organization, availability of clinical cases, performance of block coordinator, cooperation with students, and organization of clinical activities. Block coordinator's motivation and commitment affects quality of block organization and student`s success. Faculty training programs should include block management competencies and components identified through self-determination theory for improving the intrinsic motivation for students success.

The aim of this study was to assess breastfeeding knowledge, attitude and practice (KAP among female teachers in the Abha Female Educational District and identify factors that may affect breastfeeding practice in the study population. Methods A cross-sectional study using a self-administered questionnaire was conducted among school teachers in Abha Female Educational District during the months of April to June, 2011. Breastfeeding KAP of participants who had at least one child aged five years or younger at the time of the study were assessed using a self-administered questionnaire, based on their experience with the last child. Results A total of 384 women made up of 246 (61.1% primary-, 89 (23.2% intermediate- and 49 (12.8% high-school teachers participated in the study. One hundred and nineteen participants (31% started breastfeeding their children within one hour of delivery, while exclusive breastfeeding for 6 months was reported only by 32 (8.3% participants. Insufficient breast milk and work related problems were the main reasons given by 169 (44% and 148 (38.5% of participants, respectively, for stopping breastfeeding before two years. Only 33 participants (8.6% had attended classes related to breastfeeding. However, 261 participants (68% indicated the willingness to attend such classes, if available, in future pregnancies. Conclusions This study revealed that breast milk insufficiency and adverse work related issues were the main reasons for a very low rate of exclusive breastfeeding among female school teachers in Abha female educational district, Saudi Arabia. A very low rate of attending classes addressing the breastfeeding issues during pregnancy, and an alarming finding of a high percentage of babies receiving readymade liquid formula while still in hospital, were also brought out by the present study.

    Full Text Available Background: The prevalence of smoking has reduced over a period of time in the developed countries. However, the consumption of tobacco is rapidly increasing in the developing nations which further raises burden of various diseases. The prevalence of consumption of tobacco among the adolescent population is vigorously growing across the world. There are several studies in Saudi Arabia that report the smoking rate and pattern among the secondary school students, but very limited data is available about the prevalence of smoking among the college students. Therefore, the objectives of the current study are to assess the prevalence of smoking among the male college students and to evaluate the relationship between the smoking habit and socio-demographic variables. Methodology: This was a cross-sectional study done in selected colleges in King Khalid University, Abha during August 2016 to December 2016. A structured questionnaire was used to collect the socio-demographic information and about smoking habit among the college students. Results: The study showed 18.7% of prevalence of smoking among the male college students with a positive association between employment and smoking habit. However, no positive association between other socio-demographic variables and smoking. Conclusion: Though the prevalence rate of smoking among the male college students is less but still there is a need to create awareness among the college students and their parents for decreasing the burden of tobacco related diseases.

    Hydrogeochemical characteristics and assessment of water quality investigations have been carried out at Abha, located in Saudi Arabia, where Al-Saad Lake represents a rare example of natural endorheic lake. The ecosystem within and around the Al-Saad Lake including catchment area is of great social, cultural, aesthetic, environmental and economic values to Abha. Sampling and experiments of lake water has been carried out with the aim of characterizing the main physico-chemical parameters, such as DO, EC, TDS, Mg2+, Ca2+, Na+, K+, SO4 2-, Cl-, HCO3, NO3 - and F- concentration. The ordinary kriging (OK) method was used to produce the spatial patterns of water quality. The Result of DO (mean 5.38 mg/L) trend in Al-Saad Lake is not very encouraging as majority of the lake area is under DO stress or marginally above it. So, proper management strategies are needed to be formulated to protect flora and fauna of the lake. Furthermore, the chemical analysis results show the abundance of the major cations in the order Mg2+ > Ca2+ > Na+ > K+ whereas the abundance of anions are in the order SO4 2- > Cl- > HCO3 > NO3 - > F-. The result obtained in this investigation inferred that the cations in water i.e. sodium and iron are within the permissible limits but magnesium and potassium have exceeded the permissible limit. Whereas anions such as nitrate and fluoride are within the permissible range but chloride and sulphate have exceeded the permissible limits. The concentration of cation, magnesium (Mg) and potassium (K) in the lake water has exceeded the desirable range (30, 10 mg/L, respectively). This may be due to weathering and transported from rocks and particularly from sulphate deposits such as gypsum and anhydride and subsequently ends up in water. The concentration of anion, Sulphate (SO4) and chloride are above the desirable limit. The major source of bicarbonate are the carbonate rocks containing calcite (CaCO3) and dolomite (CaMg (CO3)2), Calcium (Ca) and Magnesium

    Adolescence is characterized by rapid physiological, social and cognititive changes. Aim of the present work is to study mental health of Saudi adolescent secondary school girls in Abha city, Aseer region, Saudi Arabia. A cross-sectional study was conducted in 10 secondary schools for girls using the Arabic version of the symptom-revised checklist 90 (SCL 90-R), a mental health questionnaire that was administered to the girls by fourth-year female medical students. The most prevalent mental symptoms in the 545 female students were phobic anxiety (16.4%), psycchoticism (14.8%), anxiety (14.3%), and somatization (14.2%). The prevalence of depression, paranoid ideation and interpersonal sensitivity amounted to 13.9%, 13.8% and 13.8%, respectively. The least prevalent mental symptoms were hostility (12.8%) and obsessive-compulsive behavior (12.3%). Overall, psychological symptoms (in terms of a positive global severity index) were found in 16.3% of the girls. In a multivariate logistic regression analysis, no significant relationship was found with sociodemographic factors. Psychological symptoms and disorders are prevalent in secondary school girls and health professionals need to be able to recognize, manage and follow-up mental health problems in young people. Further research is needed to explore the magnitude of the problem at the national level. (author)

    Aim: To study the awareness, attitude, practice and facilities among the different categories of dental laboratories in Abha city. Materials and Methods: A total of 80 dental technicians were surveyed in the study. The dental laboratories included in the study were teaching institute (Group I), Government Hospital (Group II), Private Dental Clinic (Group III) and Independent laboratory (Group IV). The pre-tested anonymous questionnaire was used to understand knowledge, attitude, facilities, practice and orientation regarding biomedical waste management. Results: The knowledge of biomedical waste categories, colour coding and segregation was better among Group I (55-65%) and Group II (65-75%). The lowest standard of waste disposal was practiced at Group IV (15-20%) and Group III (25-35%). The availability of disposal facilities was poor at Group IV. The continuous education on biomedical waste management lacked in all the Groups. Conclusion: The significant improvement in disposal facilities was required at Group III and Group IV laboratories. All dental technicians were in need of regular training of biomedical waste management. Clinical Significance: The dental laboratories are an integral part of dental practice. The dental laboratories are actively involved in the generation, handling and disposal of biomedical waste. Hence, it is important to assess the biomedical waste management knowledge, attitude, facilities and practice among different categories of dental laboratories. PMID:26962373

    Full Text Available Introduction: Demand for orthodontic treatment is increasing in Saudi Arabia. An observational study was planned to assess the incisor crowding in maxillary and mandibular arch among Saudi males and females reporting to different dental clinics in Abha city, Kingdom of Saudi Arabia (KSA. Materials and Methods: A cross-sectional study was conducted. Five hundred and thirty-two study casts of males and females aged between 16 and 35 years without a previous history of extraction of permanent teeth were included in the study. Labiolingual linear displacement of anatomic contact points of each maxillary and mandibular incisor from the adjacent tooth was measured. Right canine mesial aspect to the left canine mesial aspect was examined for five displacements. Results: There was a high prevalence of incisor crowding observed in the study population. Sixty-four percent (342 out of 532 casts showed bi-maxillary crowding, 14% (75 out of 352 showed mandibular, and 8.1% (43 out of 532 showed maxillary crowding. About 13.6% (72 out of 532 of the study population had well-aligned maxillary and mandibular incisors while 86.4% (460 out of 532 had some degree of incisor crowding. Females had more incisor crowding (48.5%-258 out of 532 than males (37.9%-202 out of 532. Conclusion: High prevalence of incisor crowding in Abha region reported in this study necessitates long-term planning and preventive measures for the adolescent population and treatment of the adult population of the Abha city, KSA.

    We explored the possibility of the cryo-storage of cord blood hematopoietic stem cells (CBHPSC) with respect to the quantity, quality and biologic efficacy of high altitude (HA) region Abha against sea level (SL) region. The results of the post-processed total nucleated cell count was 8.03 ± 0.31 × 10 7 and 8.44 ± 0.23 × 10 7 cells in the HA and SL regions respectively. The mean post processing viability of the nucleated cells was about 87.03 ± 1.39 (HA) and 88.33 ± 1.55% (SL) while post thaw cells were 85.61 ± 1.44 (HA) and 86.58 ± 1.61% (SL) after transient cryo-storage. The proliferation of CBHSCs after thawing were comparable between the HA and SL regions. The results of the colony forming unit (CFU) assays of CFU-E, CFU-GEMM, CFU-GM and BFU-E were comparable between HA and SL in both fresh and post thaw, while a declining trend with viability was significant. The differentiation capability of post thaw samples into adipocytes and osteocytes were comparable between HA and SL regions. Overall from the results, it can be evidenced that HA cord blood collection, processing or storage does not hinder the quality or biological efficacy of the CBHPSC.

    The weather in Abha was characterized by a temperature of 11.7-23.7 degree C, a relative humidity 0f 40-92% and rainfall of 0.2-275mm during a study period of 1990 and 1991. More ticks infested the goats in 1990 than in 1991 while more ticks infested sheep in 1991 than in 1990. The tick species collected monthly from 10 goats during these years were, respectively, Rhipicephalus turanicus (95.1 and 67.1%), Haemaphysalis sulcata (4.0 and 25.8%), Hyalomma anatolicum anatolicum (0.2 and 1.0%) and H. impeltatum (0.7 and 6.1%). Goat infestation rate with R. turanicus was 60-100% in 1990 with peaks in January, April, July, November and December when 90-100% of the goats were infested with 6.3-8.3 ticks/goat. In 1991, goat infestation rate was 10-100% with peaks in April, July and December when all goats were infested with 5.6-9.0 ticks/goat, with a sex ratio of 0.40:1-2.00:1 in both years, respectively. The ticks collected monthly from 10 sheep during these years were, respectively, R. turanicus (89.2 and 86.2%), Haem. sulcata (5.7 and 4.9%), H. a. anatolicum (1.2 and 1.0%), H. a. excavatum (0.7 and 1.2%), H. dromedarii (0.9 and 0.4%), H. marginatum rufipes (1.4 and 4.1%), H. m. turanicum (0.0 and 1.2%) and H. impeltatum (0.9 and 1.0%). Sheep infestation rate with R. turanicus was 30-100% in both years with a peak in June in 1990 when all sheep were infested with 13.8 ticks/sheep and 2 peaks in April and June in 1991 when all sheep were infested with 25.0-29.6 ticks/sheep, with a sex ratio of 0.2:1-2.6:1 and 0.6:1-4.5:1 in these years, respectively. The change in R. turanicus infestation in goats and sheep was not correlated with temperature, relative humidity or rainfall during both years except for the infestation in sheep in 1991, which was positively correlated with rainfall. With the exception of R. turanicus and Haem. sulcata, the other tick species infest primarily animals other than sheep and goats. It is recommended that control measures be directed toward the

    Abha is the capital of Asir province in Saudi Arabia. It is situated 2200 meters (7200 ft) above the sea level in the fertile mountains of the south-western Saudi Arabia. One of the most important structures of this region is Abha dam that acts as a barrier that impounds water or underground streams thereby retaining the ground water of the region. With the passage of time, various environmental factors such as ground movement, wind and changes in temperature may have significant effect on these various structure factors and may lead to invisible cracks and other structural defects. Because the dams and tunnels are prone to sudden collapse, there is potential great risk to lives of the people and significant economic loss in this area. The use of the ground penetrating radar (GPR) and electric resistivity techniques is a non-invasive scan and could assess the conditions of various built structures as well as the earth beneath or surrounding it. So the GPR system with appropriate types of antennas (1.5 GH, 1 GH, 400 MH and 100 MH) and electrical resistivity in one dimension (VES) and two dimensions (electrical profiling and imaging) is used in this work. This work aims to investigate the dam structure, developing cracks or areas of increased moisture. Also to study the surrounding areas to detect seepage from pond that may affect nearby buildings and the dam itself. It reveals that, the depth of water bearing layer ranges from 2 m to 10 m, where the three geoelectric layers are present. The first layer has resistivity values ranging from 44 Ω m-1200 Ω m with thickness ranging from 3 m to 18 m that is interpreted as the wadi deposits. The second layer having resistivity values from 11 Ω m to 137 Ω m is interpreted as the water saturated in the fractured basements. The third layer of resistivity values ranging from 2200 Ω m to 90,000 Ω m is interpreted as dry, massive basements. The GPR results provided internal images of the slab, showing its morphology, areas

    Full Text Available O objetivo do estudo foi interpretar e compreender a institucionalização da saúde pública paulista nos anos 1930-1940, com base na história das especialidades médicas. Foram analisadas novas fontes documentais em diálogo com a literatura existente, levando à identificação de novos indícios relativamente à questão eugênica e à presença de crenças religiosas de médicos como um movimento social. Os médicos, à medida que se especializavam como sanitaristas, propunham um projeto para elevar a raça brasileira, mesclando discursos higienistas com ações sanitárias. São Paulo buscou a primazia nesse projeto, por se acreditar um Estado detentor de uma raça já constituída de “homens historicamente saudáveis”. Crenças religiosas influenciaram o debate e as decisões de época para a ordem sanitária. Historicamente, o discurso sanitário compõe questões técnico-científicas com as político-ideológicas e as culturais, produzindo uma mescla dos diferentes interesses e perspectivas de ordem corporativa da profissão.

    Full Text Available Rationale: Several recent studies suggest that Brazil’s Estratégia Saude de Familia (Family Health Strategy-FHS has contributed to declines in mortality at the national and regional level. Comparatively little is known whether this approach is effective in urban populations with relatively easy access to health services. Objectives: To use detailed medical data collected as part of São Paulo’s Western Region project to examine whether the FHS program had an impact on child health in São Paulo, Brazil. Results: No associations were found between FHS and birth weight (OR 1.03, 95% CI 0.93–1.29, gestational length (OR 0.98, 95% CI 0.83–1.15 or stillbirth (OR 1.51, 95% CI 0.75–3.03.

Since then, the religious scholars, or ulama, have played an important role that is still vital to the continued survival of the Saudi regime’s credentials. However, that role has changed overtime. Historically, the AlSaud and the ulama were elites of equal standing, but oil reso...

    Several recent studies suggest that Brazil's Estratégia Saude de Familia (Family Health Strategy-FHS) has contributed to declines in mortality at the national and regional level. Comparatively little is known whether this approach is effective in urban populations with relatively easy access to health services. To use detailed medical data collected as part of São Paulo's Western Region project to examine whether the FHS program had an impact on child health in São Paulo, Brazil. No associations were found between FHS and birth weight (OR 1.03, 95% CI 0.93-1.29), gestational length (OR 0.98, 95% CI 0.83-1.15) or stillbirth (OR 1.51, 95% CI 0.75-3.03). FHS eligibility was associated with a 42% reduction in the odds of child mortality (OR 0.58, 95% CI 0.34, 0.91), with largest effect sizes for the early neonatal period (OR 0.18, 95% CI 0.04-0.79). Community based health delivery platforms may be a highly effective way to reduce neonatal mortality in urban areas of low and middle income countries, even when access to general health services is almost universal.

    Full Text Available OBJETIVO: Descrever as concepções de agricultores ecológicos sobre alimentação saudável. MÉTODOS: Estudo com abordagem qualitativa. Entre janeiro e fevereiro de 2007, foram realizadas entrevistas em profundidade com o apoio de um roteiro com 11 mulheres e um homem residentes em comunidade agrícola de Rio Branco do Sul, PR, selecionados aleatoriamente dentre as 20 famílias de agricultores ecológicos desse município. RESULTADOS: Três categorias de análise foram identificadas: "tomada de consciência da alimentação saudável", "capacidade de compra" e "terra saudável". O significado da alimentação saudável para as mulheres agricultoras envolve a ideia de que os alimentos devem ser naturais, sem agrotóxicos nem produtos químicos industrializados. Cotidianamente o consumo de frutas, verduras e legumes somado ao básico feijão, arroz e carne deve ser abundante e a composição do prato deve visar à prevenção de obesidade e doenças crônico-degenerativas. O cuidado com os recursos naturais para garantir a produção de alimentos saudáveis, a segurança alimentar, a sustentabilidade do meio ambiente e a vida futura do planeta integram o conceito de alimentação saudável. CONCLUSÕES: O conhecimento, a autocrítica e o discernimento acompanharam as concepções em relação à alimentação saudável.

    Full Text Available O direito humano à alimentação adequada (DHAA foi consagrado na Carta Magna brasileira, reconhecendo na dignidade da pessoa humana o seu fundamento. Admitindo esta garantia jurídica como pré-condição para uma reflexão ética, defendo neste artigo a necessidade de utilizar a doutrina kantiana dos deveres e do cuidado de si para fundamentar a escolha de uma alimentação saudável como um dever de virtude, para o que será necessário estabelecer a dimensão moral da alimentação no âmbito da filosofia de Kant. O objetivo é mostrar a aplicação da filosofia prática de Kant na elaboração de uma nova abordagem dos problemas alimentares atuais. Minha defesa deve ser vista como complemento ao argumento da utilidade do alimento em geral presente nas políticas e programas públicos voltados para a alimentação, nutrição e segurança alimentar, que destacam os benefícios pessoais e coletivos obtidos a partir da escolha de uma alimentação saudável.

Estudos longitudinais de populações "saudáveis" em idade laboral nas grandes metrópoles brasileiras são ainda escassos. Nessas metrópoles, a vida contemporânea pode modificar características de várias exposições e possivelmente seus efeitos; por outro lado, as condições vigentes de vida e trabalho de seus habitantes impõem dificuldades especiais à condução de estudos de coorte, com previsão de longo período de acompanhamento, em amostras da população geral. Populações de funcionários públicos apresentam patamar de escolaridade que permite a utilização de métodos eficientes de coleta de dados (por exemplo, autopreenchimento de questionários, heterogeneidade socioeconômica, e estabilidade do vínculo de trabalho que facilita o seguimento. Serão acompanhados 3.253 funcionários de uma universidade pública no Rio de Janeiro, que participaram da coleta de dados de base (fases 1 e 2, 1999-2001. Foram aplicados questionários autopreenchíveis e aferidos peso, altura, circunferência da cintura e pressão arterial. O estudo tem como foco principal a investigação de determinantes sociais da saúde. São detalhadamente investigados marcadores de posição socioeconômica, raça/etnia, religião, história conjugal e de migração. Enfatiza-se a aferição de indicadores relativos, como desigualdade e trajetórias sociais, e efeitos contextuais das áreas de residência e setores de trabalho.

    Full Text Available Considerando-se a evidente busca por alimentos de rápido e fácil preparo, as comunidades industrial e científica vêm investindo no desenvolvimento de novos produtos que, além de atenderem a essa demanda, possam oferecer benefícios à saúde do consumidor. Dentre os alimentos que não demandam muito tempo para o preparo no domicílio, o hambúrguer merece destaque, em função do seu elevado consumo. No entanto, em razão de conter gordura saturada e por ser submetido a processo de fritura, o consumo demasiado desse produto pode ser prejudicial à saúde humana, podendo causar doenças crônicas, entre as quais, a obesidade e a hipertensão. Estudos têm demonstrado a possibilidade de substituição de ingredientes na formulação de hambúrgueres, com a intenção de incorporar substâncias com propriedades funcionais; portanto, substâncias que possam contribuir para a saúde e o bem-estar dos consumidores. Nesse contexto, esta revisão aborda questões referentes ao hambúrguer, no sentido de conceituar o produto e, à luz da literatura, oferecer alternativas possíveis e que têm sido estudadas para tornar esse alimento mais saudável, com foco na substituição de gordura animal por fibras e na redução do teor de cloreto de sódio.

MÉTODOS: Foram analisados dados de 14.193 indivíduos com idades entre 18 e 29 anos, referentes ao sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL, realizado nas 27 capitais brasileiras em 2006. Foi considerado saudável quem não fuma, pratica atividade física regular e consome frutas/hortaliças cinco ou mais dias na semana. Foi analisada associação entre comportamento saudável com variáveis sociodemográficas e indicadores de saúde. A análise dos dados baseou-se na razão de prevalência obtida por regressão de Poisson. RESULTADOS: A prevalência de jovens saudáveis foi de 8,0%; 39,6% relataram dois comportamentos saudáveis, 45,3% relataram um, e 7,0% nenhum. Na análise multivariada, o comportamento saudável foi mais freqüente entre participantes com 25-29 anos, escolaridade maior que nove anos de estudo e que relataram haver local para praticar esportes próximo à residência. A freqüência de comportamento saudável foi significativamente menor entre participantes que relataram cor de pele parda ou preta, consumo de leite integral e de carne vermelha ou frango com gordura, estar em dieta e autopercepção da saúde como ruim. CONCLUSÕES: Indivíduos com menos comportamentos saudáveis percebem sua saúde como ruim, sugerindo que estes comportamentos influenciam negativamente a percepção da própria saúde. O fato de jovens mais saudáveis terem maior escolaridade, serem de cor branca e morarem próximo a local para praticar esportes sugere desigualdades no acesso a práticas saudáveis.OBJETIVO: Estimar la prevalencia de características asociadas a comportamientos saludables en jóvenes.

Ressalta-se que nenhum adolescente aderiu a todos os passos recomendados A maior frequência de adesão foi encontrada no passo 4, referente ao consumo de arroz e feijão; e menores frequência de adesão nos passos 7, referentes ao consumo de refrigerantes, sucos industrializados, doces e guloseimas, e passo 3, relativo ao consumo de Frutas/legumes/hortaliças. A adesão aos "10 passos para uma alimentação saudável" pelos adolescentes foi muito baixa. Considerando a importância de uma alimentação saudável na adolescência, recomenda-se maior investimento em políticas públicas na área de alimentação e nutrição.

    Full Text Available O objetivo deste estudo foi analisar as diferenças nas estimativas de três variantes da expectativa de vida saudável dos idosos no Brasil de 1998 para 2008: expectativa de vida livre de incapacidade funcional, com percepção de saúde boa e livre de doenças crônicas. Empregou-se o método de Sullivan, combinando as tábuas de vida do Instituto Brasileiro de Geografia e Estatística (IBGE para 1998 e 2008 e estimativas intervalares das prevalências de incapacidade funcional, percepção de saúde e doenças crônicas da Pesquisa Nacional por Amostra de Domicílios (PNAD 1998 e 2008. Além do aumento da expectativa de vida, observaram-se aumentos significativos e similares da expectativa de vida saudável nas dimensões de percepção do estado de saúde e incapacidade funcional em quase todas as idades. As mulheres apresentaram maiores expectativas de vida, se comparadas aos homens, porém esperaram viver por mais tempo com saúde ruim, independentemente do indicador utilizado para mensurar saúde. Mesmo que a forma de mensurar saúde possa variar entre os estudos, dificultando comparações, é notável a desvantagem feminina em relação à expectativa de vida saudável.

    Full Text Available O Relatório de Bellagio sobre Agricultura Saudável, Alimentação Saudável, Populações Saudáveis foi baseado em ciência, mas politicamente orientado. Foram amplamente discutidos o papel e a quantidade de nutrientes saudáveis e não saudáveis em alimentos que podem estar subjacentes à epidemia de doenças não transmissíveis em todo o mundo, com atenção ao conteúdo relativo de ácidos graxos ômega-3 e ômega-6, e também de açúcar, especialmente frutose. O relatório conclui que o consumo de açúcar, principalmente na forma de frutose de alta energia em refrigerantes, representa uma grande e insidiosa ameaça à saúde, e a maioria das dietas é deficiente em ácidos graxos ômega-3 e muito rica em ômega-6 ácidos graxos. A reunião estabeleceu que: os governos devem elevar, como uma questão de urgência, a Nutrição para uma posição de prioridade nacional; o acesso a uma dieta saudável deve ser considerado um direito humano; e a responsabilidade principal sobre a Nutrição deve ser colocada nas mãos do Ministério da Saúde, em vez do da Agricultura, para que os requisitos de saúde conduzam as prioridades agrícolas, e não vice-versa.

    Full Text Available Objetivo: A presente pesquisa objetiva investigar o imaginário coletivo de estudantes de Educação Física sobre a vida saudável. Metodologia: Foi realizada uma entrevista coletiva com 27 alunos do curso de Educação Física, organizada ao redor do uso do Procedimento Desenhos-Estórias com Tema "uma pessoa que leva uma vida saudável". As produções foram consideradas à luz do método psicanalítico em termos de produção interpretativa dos campos de sentido afetivo-emocional subjacentes ao material obtido. Resultados: O trabalho interpretativo permitiu a percepção de um campo denominado "responsabilidade individual", que se estrutura a partir da crença de que a saúde seria um estado que depende primordialmente de iniciativas e ações individuais. Conclusões: O quadro encontrado indica que o campo opera efeitos positivos, no sentido do fortalecimento da iniciativa pessoal, mas gera, como consequência problemática, um obscurecimento acerca da importância de fatores ambientais, que dependem de ações sociais e governamentais.

Trata-se de um estudo avaliativo de impacto, envolvendo 340 crianças com idades entre 6 e 12 meses, acompanhadas nas unidades básicas de saúde. Os desfechos avaliados foram prevalência do consumo de verduras, legumes, frutas e alimentos não saudáveis, e prevalência de alimentos com consistência adequada para a idade. A regressão de Poisson revelou que a ENPACS esteve associada a uma redução de 32% no consumo de refrigerante e/ou suco industrializado, 35% no de comidas industrializadas e 5% no consumo de alimentos não saudáveis. Não houve aumento no consumo de frutas, legumes, verduras e alimentos com consistência adequada para a idade. Conclui-se que o efeito positivo da estratégia foi parcial, mas que ela tem potencial de contribuir para a melhoria da alimentação infantil, haja vista sua efetividade na redução do consumo de alimentos não saudáveis.

    Full Text Available RESUMO: Objetivo: Investigar os determinantes da autoavaliação de saúde (AAS no Brasil e a influência dos comportamentos saudáveis. Métodos: Foram usados os dados da Pesquisa Nacional de Saúde (PNS de 2013. A AAS foi categorizada em muito boa/boa, regular, ruim/muito ruim. Foram testadas diferenças na distribuição da AAS segundo faixa de idade e sexo e foram usados modelos de regressão logística para investigar os efeitos de grau de escolaridade, raça/cor e presença de pelo menos uma doença crônica não transmissível (DCNT sobre a AAS ruim/muito ruim. Adicionalmente, testou-se a influência dos comportamentos saudáveis, controlando-se os efeitos dos fatores sociodemográficos e presença de pelo menos uma DCNT. Resultados: Foram analisados 60.202 indivíduos, 66,1% avaliaram o seu estado de saúde como muito bom/bom, e 5,9%, como ruim/muito ruim; 47,1% referiram o diagnóstico de pelo menos uma DCNT; e apenas 9,3% disseram ter "estilo de vida saudável" (não usa produtos de tabaco, consome frutas e hortaliças e pratica atividade física no lazer. Entre os fatores sociodemográficos, idade, sexo, grau de escolaridade e raça mostraram associações significativas com a AAS, bem como a presença de pelo menos uma DCNT. Os efeitos de todos os comportamentos saudáveis foram significativos, mesmo após o controle dos demais determinantes. Conclusão: Embora a adoção dos comportamentos saudáveis no Brasil ainda seja insuficiente, a associação dos hábitos saudáveis com a percepção da saúde encontrada neste estudo é um indício de que a população brasileira já começa a relacionar os comportamentos saudáveis ao seu bem-estar e à avaliação melhor da saúde.

    Full Text Available A escola é ambiente indicado para promover hábitos alimentares saudáveis. A portaria do MEC/MS 1.010/06 instituiu várias diretrizes com esse fim. Objetivando verificar as condições de implantação dessa portaria, fizemos um estudo qualitativo em quatro escolas particulares de Manaus, licenciadas pela Vigilância Sanitária, com descrição de práticas alimentares e práticas pedagógicas. Realizamos observações, entrevistas e grupos focais. As práticas alimentares observadas foram quanto aos alimentos disponíveis para consumo na escola. Três das quatro escolas apresentaram proporção maior de alimentos não saudáveis do que de saudáveis. Das entrevistas com diretores ou coordenadores pedagógicos e com responsáveis pela cantina e dos grupos focais com professores, pudemos perceber que a portaria em questão era desconhecida nessas escolas, mas que algumas atividades, no sentido de atendê-la, eram realizadas em sala de aula ou nos momentos de refeição; e que havia um bom conhecimento acerca das práticas alimentares dos alunos. Porém, existe necessidade de capacitação destes profissionais das escolas e inserção de nutricionista para as atividades de educação nutricional. A necessidade de envolvimento dos pais e a questão financeira foram outros desafios citados. A efetivação da promoção da alimentação saudável precisa ser estimulada e cobrada pelo setor público com medidas educativas e regulatórias. --------------------------------------------------------------------------------------------- The school environment is favorable for promoting healthy eating habits. The ordinance of the Ministry of Education and Ministry of Health nº. 1.010/06 has established several guidelines for this purpose.

    Maria do Socorro Machado Freire

    Full Text Available Resumo Estudos na área da saúde pública consideram a intersetorialidade uma estratégia de promoção de equidade no enfrentamento dos determinantes sociais da saúde. O município de Sairé, membro da Rede Pernambucana de Municípios Saudáveis (RPMS, se destaca pela adoção de uma política intersetorial denominada Sairé Mais Saudável. Este estudo visou conhecer como essa política impulsionou a equidade local. Foi realizado um estudo de caso que utilizou linha do tempo com registro de eventos críticos, análise documental, entrevistas e observação participante. Como referência teórica, utilizou-se a Teoria Ator -Rede, o que permitiu que fosse evidenciada a importância da adoção da política municipal para o empoderamento e equidade local. Os resultados, alicerçados na linha do tempo, demonstraram que foi necessário haver inicialmente uma tradução cognitiva, realizada mediante a influência e a responsabilidade direta da RPMS, a qual facilitou uma segunda tradução, desta vez estratégica, com a construção da política ancorada no programa municipal e que agora está sendo traduzida logisticamente em ações concretas direcionadas à equidade. O papel de uma liderança estratégica, valorização da formação e do que já estava construído foram categorias fundamentais nesse processo de mudança local.

  18. Percepções sobre adoção e aconselhamento de modos de vida saudáveis por profissionais de saúde

    Directory of Open Access Journals (Sweden)

    Taís Rocha Figueira

    Full Text Available O artigo teve como objetivo comparar a percepção de profissionais da atenção primária sobre aconselhamento de modos de vida saudáveis antes e depois de uma intervenção educativa. Trata-se de estudo qualitativo desenvolvido com 22 profissionais de um centro de saúde de Belo Horizonte, Minas Gerais. A entrevista estruturada foi aplicada antes e depois da intervenção educativa, e os dados foram submetidos à análise de conteúdo. Os resultados mostram a dificuldade dos profissionais em adotar e aconselhar modos de vida saudáveis, com poucas mudanças em suas percepções após a intervenção educativa. As dificuldades estavam relacionadas a questões financeiras, culturais, de vida e de trabalho, bem como a concepções conservadoras. Predominou a prática curativista com responsabilização individual e o enfoque sobre hábitos alimentares e de atividade física. Identificou-se que, após a intervenção educativa, um número maior de profissionais estava sensibilizado quanto às atividades educativas coletivas e lúdicas e à importância da atuação multiprofissional. Assim, é vista a necessidade de continuidade da educação permanente dos profissionais de modo que permita a reflexão sobre concepções de saúde possíveis no contexto contemporâneo, favorecendo a produção do cuidado e da autonomia.

The first analysis was cross-sectional in design and the additional analysis, a case-control design. In the first analysis, 745 subjects were enrolled. Additional analyses, made in 46 apparently healthy elderly subjects (AHE and 33 young adults (YA included: clinical, hematological and biochemical analyses, 24-hours nutritional recall and diet frequency questionnaire. The AHE were selected using the Senieur test protocol. To avoid selection bias in the AHE sample, additional analysis comparing cultural, socioeconomic, and health variables were compared between AHE and non-selected elderly with same dysfunction or morbidity (DE. The prevalence of AHE was 6.17% (n=46 among whom 4.3% were anemic. There were no statistically differences in hematocrit, hemoglobin, leukocytes and vitamin B12 levels between AHE and YA groups. Mean values of MCV, RDW, eosinophils, folate and ferritin were higher in the AHE than the YA group. On the other hand, platelets were higher in the YA group. No statistically significant difference occurred between the AHE and DE groups when nutritional indicators were compared. The comparison between nutritional indicators of anemic and non-anemic apparently healthy elderly people showed statistically significant differences in vitamin B12 and protein intake, which were lower in the anemic elderly. The results suggest independent biological differences between hematological parameters of elderly and young individuals.Foi realizado um estudo não probabilístico em idosos que vivem na comunidade.

    2016-03-01

    Full Text Available O herpes zoster (HZ resulta da reativação do vírus varicela-zoster (VVZ. A incidência aumenta com a idade, sendo raro em crianças saudáveis. Descrevemos um caso de HZ oftálmico numa menina de 29 meses, previamente saudável. Apresentava febre e erupção cutânea vesicular dolorosa no território oftálmico do nervo trigémio. Sem história de varicela ou vacinação anti-varicela prévias. Teve contacto intrafamiliar com varicela aos dois meses de idade. A pesquisa do vírus nas vesículas por polimerase chain reaction foi positiva. Os títulos de IgG e IgM anti-vírus varicela-zoster foram inicialmente negativos, tendo ocorrido seroconversão oito semanas depois. Medicada com aciclovir endovenoso, recuperou sem sequelas. O HZ pode ocorrer em crianças previamente saudáveis, sem evidência de varicela anterior e com serologia para VVZ negativa. Tal pode ser explicado pela imaturidade do sistema imunológico, assim como pela transferência transplacentária de anticorpos maternos, aquando da infeção primária precoce.

    Full Text Available Resumo Objetivos: Descrever o conceito dos primeiros mil dias, sua importância para a saúde e ações a serem implantadas, em especial pelos pediatras, para que a criança alcance nutrição e desenvolvimento saudáveis. Fonte dos dados: Revisão não sistemática nas bases SciELO, Lilacs, Medline, Scopus e Web of Science nos últimos dez anos com os termos mil dias, nutrição infantil, desenvolvimento infantil, infância, criança. Busca não sistemática na Internet de organizações que adotam o conceito dos mil dias e emitem recomendações sobre a saúde da criança. Síntese dos dados: Os primeiros mil dias vão da concepção até o fim do segundo ano de vida. É um importante período para intervenções que garantam nutrição e desenvolvimento saudáveis, que trarão benefícios em todo o ciclo de vida. As crianças devem receber alimentação adequada, por meio de nutrição pré-natal adequada, aleitamento materno exclusivo nos primeiros seis meses, adição de alimentos complementares adequados e continuação da amamentação até os dois anos. Face à condição de dependência absoluta de cuidados de um adulto, é fundamental que tenham um ambiente propício e acolhedor necessário para desenvolver laços fortes com seus cuidadores e lançar as bases para um desenvolvimento pleno e saudável. Conclusões: O pediatra, junto com outros profissionais, pode atuar na promoção de ações com ênfase no conceito dos primeiros mil dias que garantam a nutrição e o desenvolvimento saudáveis da criança. Focalizar ações nesse período poderá aumentar as chances de a criança ter uma vida saudável e produtiva no futuro, fortalecer famílias e comunidades e contribuir para quebrar o ciclo intergeracional da pobreza.

Testes cutâneos de hipersensibilidade tardia (DTH podem ser empregados para avaliar in vivo respostas celulares a antígenos comuns. MÉTODOS: DTH para derivado proteico purificado de tuberculina (PPD, esporotriquina, tricofitina, candidina e estreptoquinase/estreptodornase foram realizados. Foram testados crianças/adolescentes infectados pelo HIV-1 (n=36 e indivíduos saudáveis (n=56, soronegativos para HIV-1/HIV-2 pareados por sexo-idade, todos com cicatriz vacinal por BCG. Teste exato de Fisher foi aplicado (p<0,05. RESULTADOS: Entre as crianças/adolescentes infectados pelo HIV-1, mediana de idade=8,1 anos; 20/36 eram do sexo masculino; 35 casos de transmissão vertical; 34 casos de AIDS sob terapia antirretroviral; mediana de carga viral = 3.04lc10 cópias/ml; mediana de contagem de células CD4+ = 701 células/μl. Entre os infectados e saudáveis a reatividade DTH a pelo menos um dos antígenos foi, respectivamente, 25% (9/36 e 87,5% (49/56 (p<0,001. Reatividade à candidina predominou nos infectados (8/36, 22% e ao PPD nos indivíduos saudáveis (40/56, 71,4%. A reatividade ao PPD entre infectados foi de 8,3% (p<0,01. A mediana da induração ao PPD foi 2,5mm (variação: 2-5mm entre infectados e 6,0mm (variação: 3-15mm entre os saudáveis. Não observamos correlação entre positividade ao PPD e idade. No grupo de infectados, não observamos correlação entre contagens de células CD4+ e reatividade ao DTH. CONCLUSÕES: Respostas DTH significativamente diminuídas, incluindo a reatividade ao PPD foram observadas em crianças/adolescentes infectados pelo HIV-1 comparadas com controles saudáveis, provavelmente refletindo doença avançada e supressão da imunidade mediada por células T.

But, in the realization of their mission, it is not clear to what extant these universities were successful in terms of information dissemination. The aim of this paper was to determine the core web sites and evaluate the effectiveness, ranking and collaboration rate among these websites. The formulas of core website determination, co-links and in-links analysis and revised web impact factor were used beside cluster and multidimensional analysis methods in this study. Results showed that "King Saud University" website in Saudi Arabia had the highest visibility and the most authoritative website among all university websites. Also, co-link analysis showed that major Islamic university websites had collaboration in 12 clusters based on clustering analysis and in 11 clusters based on multidimensional analysis, where two of them (Iran and Turkey were national clusters in cluster analysis method. Results analysis indicated that web designers in these universities must identify how to attract links and web traffic in order to promote the quality and content of websites. However, the ultimate success of a website was dependent upon factors such as quality, size, language, and the approximate age of a website which was not limited to one or two factors.

    Full Text Available FUNDAMENTO: A prevalência das doenças cardiovasculares (DCV tem aumentado nos últimos anos. A literatura revela que cerca de 35% dos eventos ateroscleróticos ocorrem na ausência dos fatores de risco clássicos, requerendo uma avaliação individual minuciosa para melhor caracterizar o risco. Os índices lipídicos tetravalente (LTI e pentavalente (LPI constituem uma nova e eficiente forma de avaliação do perfil lipídico e do risco para DCV. OBJETIVO: O presente estudo avaliou o LTI e o LPI em estudantes de graduação, estabelecendo estes índices em indivíduos saudáveis e correlacionando-os com o perfil lipídico tradicional. MÉTODOS: Participaram do estudo 110 estudantes, 48 (44% do sexo masculino e 62 (56% do sexo feminino, com média de idade de 20,9 ± 1,7 anos. Apolipoproteína-AI, apolipoproteína B, colesterol total, lipoproteína (a, triglicérides, HDL e LDL foram analisados usando-se métodos diagnósticos específicos. LTI e LPI foram calculados por meio das equações LTI = [colesterol total x triglicérides x lipoproteína (a / HDL] e LPI = [colesterol total x triglicérides x lipoproteína (a x apolipoproteína B / apolipoproteína A-I], respectivamente. RESULTADOS: Os valores de LTI e de LPI foram significativamente maiores nas mulheres quando comparados aos dos homens. Para os outros parâmetros, houve diferenças significativas entre os gêneros apenas para colesterol total, HDL e apolipoproteína A-I. Houve correlações positivas e significativas entre LDL e LTI e entre LDL e LPI. CONCLUSÃO: Os achados indicam que LTI e LPI estavam associados com LDL, um parâmetro não utilizado para calcular os índices lipídicos e amplamente usado na prática clínica para investigação do risco cardiovascular.

    Full Text Available Introdução e objetivo: a alimentação é fundamental para a construção de modos de vida saudáveis. Evidências científicas mostram a associação entre o maior consumo de alimentos ricos em gordura, sal e açúcar e o incremento de doenças não transmissíveis. Considerando que hábitos alimentares saudáveis devem ser fomentados em espaços como a família e as instituições de ensino, este estudo teve como objetivo descrever os alimentos e as bebidas consumidos por estudantes de Odontologia, durante a permanência nas salas de aula. Método: tratou-se de pesquisa observacional transversal, nas dependências de um Curso de Odontologia no Rio Grande do Sul. Os dados foram coletados de modo indireto através da observação e quantificação de itens descartados nas lixeiras das salas de aula, durante o período de um mês, no ano de 2015. Resultados: ao total, foram contabilizados 1301 itens. Entre os alimentos, identificou-se maior consumo de doces e miscelâneas (66,7%, seguido por biscoitos, bolos e cereais (26,5%, frutas (5,2% e iogurtes (1,6%. Quanto às bebidas, constatou-se maior consumo de café (52,0%, seguido por refrigerante (16,3%, água (12,6%, bebida achocolatada (8,3%, suco (7,1% e outros (3,7%. Evidenciou-se maior presença de itens ultraprocessados, hipercalóricos, pouco nutritivos e com grande quantidade de açúcares livres. Considerações finais: a realização de atividades de educação em saúde, incentivo à oferta e à comercialização de alimentos e bebidas saudáveis deve ser estimulada como um meio para a promoção da saúde. Instiga-se a adaptação e o uso de métodos alternativos para a verificação do consumo de alimentos e bebidas por grupos de indivíduos, como os descritos neste estudo, em novas investigações.

Realizaram-se quatro grupos focais com 25 adolescentes com perguntas sobre: percepção e motivação para modificar a dieta; conceito de alimentação saudável e barreiras para sua adoção; e características de impressos para a promoção de práticas alimentares saudáveis. Observou-se uma freqüente indecisão quanto a classificar a dieta como saudável. Os adolescentes referiram não se sentir confiantes para modificar a dieta, mas relataram conceitos adequados sobre alimentação saudável. As principais barreiras citadas foram focadas em aspectos pessoais e sociais, como: a tentação, o sabor dos alimentos, a influência dos pais e a falta de tempo e de opções de lanches saudáveis na escola. Para os jovens, materiais educativos de promoção de alimentação saudável devem reforçar seus benefícios imediatos e destacar mensagens alarmantes sobre os riscos à saúde advindos de uma alimentação inadequada.The aim of this study was to evaluate perceptions, barriers, and characteristics of teaching materials to promote healthy eating, as described by teenagers. Four focus groups were conducted with 25 adolescents, including questions on: perceptions regarding diet and motivations to change; concepts of (and barriers to healthy eating; and characteristics needed for teaching materials to promote healthy eating. The teens were often undecided when attempting to classify a diet as healthy. They generally reported feeling insecure about making dietary changes, but showed adequate notions of healthy eating. The main barriers involved personal and social characteristics: temptation, food flavors, parental influence, and lack of time and options for healthy snacks at school. According to these teenagers, educational materials for promotion of healthy eating should emphasize the

    To determine factors influencing final year medical undergraduate trainees at King Saud University in choosing a career in Obstetrics and Gynecology. In this cross sectional study, the undergraduate final year medical students and interns at King Saud University, Riyadh, Saudi Arabia were asked to complete a survey instrument designed to assess possible attracting and detracting factors. The survey was conducted from January 2010 to February 2010. Factors were analyzed in a univariable and multivariable analysis. The survey was distributed to 507 students. Completed questionnaires were returned by 330 participants (response rate 65%). Overall, 32 (9.7 %) of students listed Obstetrics and Gynecology in their top 3 choices. The rotation of students through Obstetrics and Gynecology was the most influential factor attracting 81.3% of the students who chose to take this course. Faculty interaction was a major reason for attracting students accounting for 71.9%, but resident interaction was less attractive where only 37.5% of students mentioned that they were affected positively by residents. Hands-on experience such as performing deliveries and other procedures were significant attracting factors. (p=0.006 and p=0.004). The findings in this study will hopefully aid in recruiting trainees to the specialty of Obstetrics and Gynecology in Saudi Arabia. Identifying the 5 major attracting factors from our study will allow our institute to integrate these factors in Obstetrics and Gynecology curriculum design, eventually increasing interest in postgraduate training in this specialty.

    Full Text Available O consumo de refeições fora de casa é uma tendência em diferentes regiões do mundo, mas há indícios de que essa prática possa apresentar riscos à saúde. É reconhecido que os comportamentos e as escolhas alimentares dos indivíduos são complexos e estão condicionados a diversos fatores. O fator ambiental vem recebendo crescente atenção dentre as variáveis que envolvem as escolhas alimentares. Nesse contexto, este artigo discute a possibilidade de os restaurantes por peso, modalidade de serviço muito utilizada na realidade brasileira, representarem uma alternativa saudável de alimentação fora de casa. Os dados científicos disponíveis relativos aos restaurantes por peso ainda são escassos, não permitindo uma avaliação sistematizada sobre o tema. Assim, com base em pesquisa bibliográfica, discutem-se os modelos praticados e alguns estudos que comparam a possibilidade de escolhas saudáveis em restaurantes com diferentes modalidades de distribuição. Sugere-se que, devido às suas características - que incluem a diversidade, a possibilidade da prática de preços acessíveis, a rapidez e a conveniência -, os restaurantes por peso possam estimular a escolha de alimentos saudáveis nas refeições realizadas fora de casa. Ressalta-se, também, a importância de intervenções nutricionais tanto na disponibilização dos alimentos quanto na orientação à população para escolhas saudáveis nesse contexto.Consumption of food away from home is a trend in different regions of the world, with indications that this practice may pose a health risk. It is recognized that eating behaviors and food choices are complex and conditioned to several factors.

    Full Text Available As mudanças alimentares na sociedade ocidental apontam para a importância de uma ação específica no campo da saúde individual e coletiva e colocam os profissionais sanitaristas como indivíduos estratégicos na promoção da alimentação saudável. O presente estudo tem o propósito de conhecer as concepções desses profissionais sobre a alimentação saudável, com base na técnica metodológica da pesquisa-ação aplicada em centros de saúde do Distrito Federal. Os resultados mostram que existe um aparente dualismo entre os conceitos envolvidos nesse tema, um que versa sobre a idealização alimentar e outro que situa o espaço da realidade concreta dos indivíduos. Ou seja, há um conceito sobre a alimentação para a saúde fundamentado na literatura científica e outro que se apóia neste, mas distingue-se no espaço interno do cotidiano. Neste último, os atores sociais fazem correspondências entre um saber e outro e trazem à tona os hábitos alimentares conjugados ao estilo de vida, mas, em ambas as concepções, a tendência é transcender o caráter biológico implícito na construção do conceito e apoiar-se nas condições sócio-culturais que as moldam e são moldadas no plano concreto da realidade.

    The sky uniformity can be noticed in studying the repartition of objects far enough. The sky isotropy description uses space rotations. The group theory elements will allow to give a meaning at the same time precise and general to the word a ''symmetry''. Universe models are reviewed, which must have both of the following qualities: - conformity with the physic known laws; - rigorous symmetry following one of the permitted groups. Each of the models foresees that universe evolution obeys an evolution equation. Expansion and big-bang theory are recalled. Is universe an open or closed space. Universe is also electrically neutral. That leads to a work hypothesis: the existing matter is not given data of universe but it appeared by evolution from nothing. Problem of matter and antimatter is then raised up together with its place in universe [fr

    Full Text Available A literatura aponta que o estresse do ambiente aliado ao estresse do exercício físico produz alterações psicológicas e fisiológicas. Portanto, o objetivo do presente estudo foi investigar a associação entre o efeito agudo do exercício físico moderado realizado em condição de atitude simulada sobre o estado de humor, saturação da oxihemoglobina e pressão arterial de jovens saudáveis. Dez voluntários realizaram 45 min. de exercício físico e passaram por duas condições: Condição Normóxia (CN e Condição Hipóxia (CH. Em ambas as condições eles responderam a dois instrumentos que avaliam as respostas de humor, a Escala de Humor de Brunel (BRUMS e a Escala Subjetiva de Experiência em Exercício (SEES, bem como a avaliação da saturação de oxihemoglobina e da pressão arterial. Esses procedimentos foram realizados antes, imediatamente após, 30 min. e 60 min. após o término do protocolo. Após a prática do exercício físico na Condição Hipóxia, os voluntários apresentaram maiores escores de Fadiga, Confusão Mental, DTH, Raiva, Distresse Psicológico e menores valores de Vigor e Bem-Estar Positivo acompanhados de uma diminuição da saturação da oxihemoglobina. O exercício físico moderado realizado em altitude simulada de 4500m promove mudanças no estado de humor e aumento da pressão arterial sistólica de jovens saudáveis.

    Alfven, H.

    1986-04-01

    Traditionally the views in our cosmic environment have been based on observations in the visual octave of the electromagnetic spectrum, during the last half-century supplemented by infrared and radio observations. Space research has opened the full spectrum. Of special importance are the X-ray-gamma-ray regions, in which a number of unexpected phenomena have been discovered. Radiations in these regions are likely to originate mainly from magnetised cosmic plasma. Such a medium may also emit synchrotron radiation which is observable in the radio region. If we try to base a model of the universe on the plasma phenomena mentioned we find that the plasma universe is drastically different from the traditional visual universe. Information about the plasma universe can also be obtained by extrapolation of laboratory experiments and magnetospheric in situ measurements of plasma. This approach is possible because it is likely that the basic properties of plasma are the same everywhere. In order to test the usefulness of the plasma universe model we apply it to cosmogony. Such an approach seems to be rather successful. For example, the complicated structure of the Saturnian C ring can be accounted for. It is possible to reconstruct certain phenomena 4-5 bilions years ago with an accuracy of better than 1 percent

    This paper discusses how the subject of baby universes and their effects on spacetime coupling constants is in its infancy and rapidly developing. The subject is based on the non-existent (even by physicists' standards) Euclidean formulation of quantum gravity, and it is therefore necessary to make a number of assumptions in order to proceed. Nevertheless, the picture which has emerged is quite appealing: all spacetime coupling constants become dynamical variables when the effects of baby universes are taken into account. This fact might even solve the puzzle of the cosmological constant. The subject therefore seems worth further investigation

    Full Text Available Writing in the University is a basic necessity and a long-range educational purpose. One of the basic characteristics of the university context is that it requires writing both as a tool of communication and as a source of intellectual stimulation. After establishing the basic features of academic writing, this article analyzes the role of writing for students (writing to learn and for teachers (write to plan, to reflect, to document what has been done. The article also discusses the contributions of writing for both students and teachers together: writing to investigate. Finally, going beyond what writing is as academic tool, we conclude with a more playful and creative position: writing for pleasure and enjoyment.

    Human life is a staggeringly strange thing. On the surface of a ball of rock falling around a nuclear fireball in the blackness of a vacuum the laws of nature conspired to create a naked ape that can look up at the stars and wonder where it came from. What is a human being? Objectively, nothing of consequence. Particles of dust in an infinite arena, present for an instant in eternity. Clumps of atoms in a universe with more galaxies than people. And yet a human being is necessary for the question itself to exist, and the presence of a question in the universe - any question - is the most wonderful thing. Questions require minds, and minds bring meaning. What is meaning? I don't know, except that the universe and every pointless speck inside it means something to me. I am astonished by the existence of a single atom, and find my civilisation to be an outrageous imprint on reality. I don't understand it. Nobody does, but it makes me smile.

    Full Text Available Resumo: A mensuração do lactato sérico é utilizada na rotina médica como marcador prognóstico de pacientes em estado de emergência. Sua interpretação não deve ser feita de forma isolada, mas conjunta aos demais parâmetros clínicos, pois seus valores podem sofrer interferência do estresse metabólico ou ambiental, contenção física e/ ou manipulação dos pacientes. Assim, buscou-se mensurar os valores do lactato sérico e parâmetros clínicos de cães saudáveis, bem como as suas correlações, durante o atendimento clínico ambulatorial veterinário. Para isso, foram avaliados 80 cães, machos ou fêmeas, com idade de um a oito anos, atendidos para revacinação anual polivalente. Foram considerados cães saudáveis os que não apresentaram intercorrências clínicas nos últimos 60 dias e alterações nos exames físicos e nos valores de hemograma e glicemia sérica. Foram mensurados inicialmente o peso corporal, a frequência cardíaca (FC e respiratória (FR, tempo de preenchimento capilar (TPC, coloração de mucosas, temperatura retal (TR, periférica (TP e a diferença entre TR e a TP, o Delta T°C. Por último, realizaram-se os exames de hemograma e glicemia sérica, juntamente com a mensuração do lactato sérico, utilizando para isso um lactímetro portátil, por meio da amostra sanguínea obtida da veia cefálica. Além disso, havendo a correlação dos valores do lactato séricos com o peso corporal os cães foram divididos conforme o cálculo do 33° e 66° percentil.

    Full Text Available PURPOSE: The present study was designed to determine the normal range of serum beta 2-microglobulin (Sb2M levels among healthy volunteers in Brazil. Levels of Sb2M are elevated in human immunodeficiency virus (HIV-infected patients and have been shown to be the best predictor of HIV infection status and of some malignant disorders, especially multiple myeloma. In order to achieve its optimal use in Brazilian clinical diagnosis, an adequate reference interval study was performed for Sb2M IMMULITE® assay, based on the fact that its reference range limits were evaluated among European populations. METHODS: Ninety-six healthy blood donors were evaluated, and Sb2M levels were measured by chemiluminescent enzyme immunoassay using the IMMULITE® automated analyzer. RESULTS: A normal range of Sb2M values, established by a nonparametric statistical method, was 1.05 to 3.9 mg/mL, with the upper limit being higher than that reported elsewhere. CONCLUSIONS: This study presented new data indicating that there is a significant difference between the current reference limits for Sb2M IMMULITE® assay and those found in Brazil, providing evidence that significant differences in range of normal values may occur among different populations, and that these new values should be considered for Brazilian individuals.OBJETIVO: O objetivo do presente estudo foi determinar valores de referência de beta2-Microglobulina sérica (Sb2M em voluntários saudáveis.

  20. Universal Alienation

    Directory of Open Access Journals (Sweden)

    David Harvey

    2018-05-01

    Full Text Available This article is part of a debate between David Harvey, Michael Hardt and Toni Negri. It takes Marx’s bicentenary as occasion for an update of his concept of alienation. The paper asks: how are we to interpret universal alienation and from whence does it come? Marx radically reformulated the concept of alienation in the Grundrisse. The humanism of the early Marx can be re-rooted and reconceptualised in the scientific mode proposed in the Grundrisse. In the Grundrisse, the universality of alienation is specific to capitalism’s historical evolution. Today, alienation exists almost everywhere. It exists at work in production, at home in consumption, and it dominates much of politics and daily life. Such trends intensify through the application of information technologies and artificial intelligence. Widespread alienation has resulted in Occupy movements as well as right-wing populism and bigoted nationalist and racist movements. Donald Trump is the President of alienation. The circulation of capital as totality consists of the three key moments of production, circulation and distribution. A lot of contemporary economic struggles are now occurring at the point of realisation rather than at the point of production. Protests are therefore today often expressions of broad-based discontent. Our future is dictated by the need to redeem our debts. Under such conditions democracy becomes a sham. The big question is what forms of social movement can help us get out of the state-finance nexus. The theory of objective alienation along with an understanding of its subjective consequences is one vital key to unlock the door of a progressive politics for the future.

    In this prospective study we wanted to determine whether perceived stress over time among students in the Preparatory Year of King Saud University (KSU) predisposes them to cardiometabolic abnormalities. A total of 110 apparently healthy Saudi students (35 men and 75 women enrolled during the 2010-2011 academic year) were included. Perceived stress was determined at baseline and 1 year later. Anthropometrics were obtained and morning fasting serum glucose, lipid profile and cortisol were measured at both times. Perceived stress was noted among 48.2% of subjects at baseline and was not significantly different after follow-up, with 45.4% scoring high. In men, the prevalence of perceived stress was 48.6% at baseline (13 out of 35) and 37.1% at follow-up (13 out of 35), while in women it was 48% at baseline and 49.3% at follow-up. Interestingly, significant improvements in the blood pressure and lipid profiles, with the exception of HDL-cholesterol, were observed in both men and women, while fasting glucose also improved in women. Serum cortisol was inversely associated to fasting glucose, and total- and LDL-cholesterol (p-values 0.007, 0.04 and 0.04, respectively). These data are opposite to findings in students entering Western universities, in whom increasing stress and a deteriorating cardiometabolic profile have been repeatedly noted. Perceived stress and morning cortisol levels among students of the Preparatory Year in KSU remained constant for both genders over time, yet an improved cardiometabolic profile was observed, suggesting good adaptation among our pre-college students in their first year of university life.

    To evaluate the relationship between the nutritional habits of university students with health parameters related to cardiovascular risk. Three hundred and twelve students (180 females and 132 males; mean age 21.1 +/- 2.8 years) attending King Saud University, Riyadh, KSA were randomly selected from the university register and invited to participate in the study during 2008-2009. Students who consented to participate completed a self-reported questionnaire including: nutritional screen, health habits, and lifestyle practice. Daily food consumption was recorded, and nutritional analysis was performed. Blood pressure (BP) was also measured. A quarter of students was found to be overweight (21%) or obese (6.5%). The percentage of overweight and obese male students was 23% and 7% compared with female students who were 19% overweight and 6% obese. There was a positive correlation between fat consumption and BMI as well as BP in both genders, between economical status and BMI (p=0.05), and between salty food and BP (p=0.05). There was a negative correlation between consumption of fiber, grains, vegetables, fruits, beans, and BMI as well as BP in both genders (p=0.05). Our findings suggest that lifestyle modification is important especially in young age groups. The preventive interventions should focus not only on obesity, but also on related diseases. There is a need for strategies and coordinated efforts to reduce the tendency of overweight and obesity among college students.

Participaram deste estudo prospectivo 30 voluntários do sexo masculino, saudáveis, não praticantes de atividade física, com valor médio de 22,40 (±3,42 anos de idade. Foram submetidos à avaliação da capacidade de produção de força isométrica, por meio de uma célula de carga adaptada. Metade dos voluntários recebeu no primeiro dia aplicação da crioterapia e no outro dia (48 horas depois a DMO, e a outra metade dos sujeitos o inverso. A crioterapia foi aplicada até que a temperatura na região bicipital atingisse 25ºC e a DMO foi aplicada até que atingisse 42ºC. Seis reavaliações do PF foram feitas ao longo de 2 horas. Houve incremento significativo no pico de força (PF até 15 minutos após a aplicação da crioterapia, a partir desse momento houve decréscimo da força isométrica máxima, no entanto, a diferença estatisticamente significativa esteve presente até 90 minutos depois. Na DMO, o PF reduziu significativamente até 15 min após a aplicação do recurso. A partir deste momento, o PF foi retornando próximo ao valor inicial. Na última avaliação, o PF reduziu novamente. A crioterapia e a DMO interferiram de maneira diferente na capacidade de produção de força muscular isométrica de flexores de cotovelo, enquanto o resfriamento gerou incremento, o aquecimento causou declínio.

    Full Text Available Healthy animals normally eat sufficient food to satisfy their energy requirements. It is one of the jobs of the nutritionist to ensure that all other nutrient needs have been met when animals stop eating because they have met their energy needs. While dogs and cats are members of the biological order Carnivora, scientific observation and research support that differences in their metabolism and nutritional requirements exist. However, the goal in feeding both species is the same; to optimize the health and well-being of the individual. This approach results in dietary recommendations that will vary from individual animal to animal, based on a variety of factors that include the animal's signalment, occupation and environment. Feeding approaches vary between the two species and within the same species during different physiological life stages. However, the practice of feeding to maintain a lean body condition is a common goal. The maintenance of a lean body condition has been proven to increase both the quantity and quality of life in dogs. Currently, similar data does not exist in cats but is suspected to hold true. Each dog and cat's feeding program should be assessed routinely and adjustments made as indicated based on the animal's body condition, life stage and general health.Animais saudáveis normalmente comem alimentos suficientes para satisfazer suas necessidades energéticas. Uma das funções dos nutricionistas é garantir que todas as necessidades de nutrientes ingeridas serão adequadas quando os animais pararem de comer após terem atingido suas necessidades energéticas. Enquanto cães e gatos são membros da ordem Carnivora, a observação científica e de pesquisa apoia as diferenças existentes em suas exigências nutricionais e o metabolismo. No entanto, o objetivo de alimentar as duas espécies é o mesmo, para otimizar a saúde e o bem-estar do indivíduo. Esta abordagem resulta em recomendações dietéticas que variam de

    Full Text Available BACKGROUND: It is well known that eccentric training increases muscle strength and promotes greater neural activation, and therefore has been used in the recovery of knee extensors. The hypothesis of this study was that there would be a strong correlation between knee extensor torque and functional tests. OBJECTIVES: To investigate the relationship between knee extensor peak torque and functional tests of agility (runs and propulsion (hop for distance after short-term isokinetic eccentric training. METHODS: Twenty healthy and active male undergraduate students (age 22.5±2.1 years; height 1.72±0.10 m; weight 67.8±9.5 kg; body mass index: 22.5±2.0 kg/m², with no abnormalities or history of injury of the limbs, performed an isokinetic assessment of the knee extensors and flexors and also functional tests before and after isokinetic training, which consisted of 3 sets of 10 MVECs at 30º/s, with 3 minutes of rest between sets, twice a week for 6 weeks. RESULTS: The eccentric training increased the extensor peak torque (16, 27 and 17%; PCONTEXTUALIZAÇÃO: Sabe-se que o treino excêntrico aumenta a força muscular, promovendo uma maior ativação neural e, portanto, tem sido usado na recuperação do torque extensor. A hipótese deste estudo foi a de que possa existir uma forte correlação entre o torque extensor do joelho e os testes funcionais. OBJETIVOS: Correlacionar o torque extensor do joelho com os testes funcionais de agilidade (corridas e impulsão (saltos em distância após o treino isocinético excêntrico de curta duração. MÉTODOS: Vinte homens universitários, ativos e saudáveis (22,5±2,1 anos; 1,72±0,10 m; 67,8±9,5 kg; IMC 22,5±2,0 kg/m², sem reportar anormalidades ou história de lesão no membro inferior, realizaram avaliação isocinética do torque extensor e flexor do joelho e testes funcionais antes e depois do treino isocinético que consistiu em três séries de 10 CEVM a 30º/s, com 3 minutos de repouso entre as

    Full Text Available FUNDAMENTO: A prevalência das doenças cardiovasculares (DCV tem aumentado nos últimos anos. A literatura revela que cerca de 35% dos eventos ateroscleróticos ocorrem na ausência dos fatores de risco clássicos, requerendo uma avaliação individual minuciosa para melhor caracterizar o risco. Os índices lipídicos tetravalente (LTI e pentavalente (LPI constituem uma nova e eficiente forma de avaliação do perfil lipídico e do risco para DCV. OBJETIVO: O presente estudo avaliou o LTI e o LPI em estudantes de graduação, estabelecendo estes índices em indivíduos saudáveis e correlacionando-os com o perfil lipídico tradicional. MÉTODOS: Participaram do estudo 110 estudantes, 48 (44% do sexo masculino e 62 (56% do sexo feminino, com média de idade de 20,9 ± 1,7 anos. Apolipoproteína-AI, apolipoproteína B, colesterol total, lipoproteína (a, triglicérides, HDL e LDL foram analisados usando-se métodos diagnósticos específicos. LTI e LPI foram calculados por meio das equações LTI = [colesterol total x triglicérides x lipoproteína (a / HDL] e LPI = [colesterol total x triglicérides x lipoproteína (a x apolipoproteína B / apolipoproteína A-I], respectivamente. RESULTADOS: Os valores de LTI e de LPI foram significativamente maiores nas mulheres quando comparados aos dos homens. Para os outros parâmetros, houve diferenças significativas entre os gêneros apenas para colesterol total, HDL e apolipoproteína A-I. Houve correlações positivas e significativas entre LDL e LTI e entre LDL e LPI. CONCLUSÃO: Os achados indicam que LTI e LPI estavam associados com LDL, um parâmetro não utilizado para calcular os índices lipídicos e amplamente usado na prática clínica para investigação do risco cardiovascular.BACKGROUND: The prevalence of cardiovascular disease (CVD has increased steadily in recent years.

Entre janeiro e fevereiro de 2007, foram realizadas entrevistas em profundidade com o apoio de um roteiro com 11 mulheres e um homem residentes em comunidade agrícola de Rio Branco do Sul, PR, selecionados aleatoriamente dentre as 20 famílias de agricultores ecológicos desse município. RESULTADOS: Três categorias de análise foram identificadas: "tomada de consciência da alimentação saudável", "capacidade de compra" e "terra saudável". O significado da alimentação saudável para as mulheres agricultoras envolve a ideia de que os alimentos devem ser naturais, sem agrotóxicos nem produtos químicos industrializados. Cotidianamente o consumo de frutas, verduras e legumes somado ao básico feijão, arroz e carne deve ser abundante e a composição do prato deve visar à prevenção de obesidade e doenças crônico-degenerativas. O cuidado com os recursos naturais para garantir a produção de alimentos saudáveis, a segurança alimentar, a sustentabilidade do meio ambiente e a vida futura do planeta integram o conceito de alimentação saudável.

The Ministry of Health, Kingdom of Saudi Arabia, introduced the Quality Assurance Guidelines with the hope to improve the management of hypertension in its centers. We conducted an audit of two Primary Health Care Centers namely, Al-Manhal (MPHCC and Al-Numais (NPHCC, to evaluate how well hypertension was managened at these centers. A check list was derived from the Quality Assurance Manual to audit the process and to assess the health outcome. A retrospective study on a chosen sample of 120 files of hypertensive patients, out of 256 from both the Primary Health Care Centers was performed, during the last three months of the year 2000. Results showed that 61% of the patients were between 45-64 years of age, 56% were females, 85% were married, 54% were illiterate and 7.5% were smokers. A total of 92% of the patients had primary hypertension and 25% had a positive family history of hypertension. Beta-blockers were the most commonly used drugs in both the centers. Although the recording of the information was not perfect, there was no statistical difference in the socio-demongraphic data and also the means of the total score in both the centres. On the other hand, carrying out the important procedures for hypertensive patients was found to be better at MPHCC in com-parison to NPHCC (p < 0.05.

    This is an excerpt from Stephen Hawking's book The Universe in a Nutshell. Roger Penrose and Stephen Hawking, Lucasian Professor of Mathematics at the University of Cambridge, were able to show that Einstein's General Theory of Relativity implied that the universe and time itself must have had a beginning in a tremendous explosion. The discovery of the expansion of the universe is one of the great intellectual revolutions of the twentieth century.

    The problems of explaining the observed isotropy, homogeneity, flatness and specific entropy of the Universe are discussed in the context of an inflationary Universe which has recently been suggested. It is shown that the isotropy cannot be ignored as a Universe with a large amount of anisotropy will not undergo the inflationary phase. A Universe with only moderate anistropy will undergo inflation and will be rapidly isotropized. (U.K.)

    International Nuclear Information System (INIS)

    Guth, A.; Steinhardt, P.

    1993-01-01

    According to the inflationary model, the universe had a brief period of extraordinary rapid expansion, or inflation, during which its diameter increased by a factor at least 10 25 times larger (and perhaps much larger still) than had been previously thought. All the matter and energy in the universe could have been created from virtually nothing. Features of this article are: comparison of standard and inflationary modes, the horizon problem, the geometry of the universe, spontaneous symmetry breaking and the Higgs mechanism (energy density of the Higgs fields), the flatness problem, the new inflationary universe (new Higgs fields and false vacuum), conserved quantities in the universe. 12 figs., 11 refs

  14. The inflationary universe

    International Nuclear Information System (INIS)

    Linde, A.D.

    1984-01-01

    According to the inflationary universe scenario the universe in the very early stages of its evolution was exponentially expanding in the unstable vacuum-like state. At the end of the exponential expansion the energy of the unstable vacuum transforms into the energy of hot dense matter. Recently it was realised that the exponential expansion of the universe naturally occurs in a wide class of realistic theories of elementary particles. The inflationary universe scenario makes it possible to obtain a simple solution to many longstanding cosmological problems and leads to a crucial modification of the standard point of view of the large-scale structure of the universe.

    People have always been fascinated with the stars above and the universe that contains them. Over the years, astronomers have developed numerous theories to explain how the universe began, how it works, and what its ultimate fate will be. But all of the scientists' questions are far from answered. The Expanding Universe goes beyond the creation of the universe to explain how scientists think the universe works, grows, and changes, including what great thinkers Isaac Newton and Albert Einstein had to say about its fate. Readers will also learn about how researchers are slowly shedding light on

    The Universe: A Biography makes cosmology accessible to everyone. John Gribbin navigates the latest frontiers of scientific discovery to tell us what we really know about the history of the universe. Along the way, he describes how the universe began; what the early universe looked like; how its structure developed; and what emerged to hold it all together. He describes where the elements came from; how stars and galaxies formed; and the story of how life emerged. He even looks to the future: is the history of the universe going to end with a Big Crunch or a Big Rip.

  17. A lightweight universe?

    Science.gov (United States)

    Bahcall, Neta A.; Fan, Xiaohui

    1998-01-01

    How much matter is there in the universe? Does the universe have the critical density needed to stop its expansion, or is the universe underweight and destined to expand forever? We show that several independent measures, especially those utilizing the largest bound systems known—clusters of galaxies—all indicate that the mass-density of the universe is insufficient to halt the expansion. A promising new method, the evolution of the number density of clusters with time, provides the most powerful indication so far that the universe has a subcritical density. We show that different techniques reveal a consistent picture of a lightweight universe with only ∼20–30% of the critical density. Thus, the universe may expand forever. PMID:9600898

  18. Universities scale like cities.

    Directory of Open Access Journals (Sweden)

    Anthony F J van Raan

    Full Text Available Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the 'gross university income' in terms of total number of citations over 'size' in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities--the top-100 European universities--we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

    Mathematics is studied in universities by a large number of students. At the same time it is a field of research for a (smaller) number of university teachers. What relations, if any, exist between university research and teaching of mathematics? Can research “support” teaching? What research...... and what teaching? In this presentation we propose a theoretical framework to study these questions more precisely, based on the anthropological theory of didactics. As a main application, the links between the practices of mathematical research and university mathematics teaching are examined...

    Mike Cox

    2004-09-01

    Full Text Available This article describes the experiences and general observations of the author at Heriot-Watt University and concerns the transfer of university technology for the purposes of commercialisation. Full commercial exploitation of a university invention generally requires transferring that technology into the industrial arena, usually either by formation of a new company or licensing into an existing company. Commercialisation activities need to be carried out in unison with the prime activities of the university of research and teaching. Responsibility for commercialising university inventions generally rests with a specific group within the university, typically referred to as the technology transfer group. Each technology transfer should be considered individually and appropriate arrangements made for that particular invention. In general, this transfer process involves four stages: identification, evaluation, protection and exploitation. Considerations under these general headings are outlined from a university viewpoint. A phased approach is generally preferred where possible for the evaluation, protection and exploitation of an invention to balance risk with potential reward. Evaluation of the potential opportunity for a university invention involves essentially the same considerations as for an industrial invention. However, there are a range of commercial exploitation routes and potential deals so that only general guidelines can be given. Naturally, the final deal achieved is that which can be negotiated. The potential rewards for the university and inventor are both financial (via licensing income and equity realisation and non-financial.

Não houve diferença para os movimentos de flexo/extensão e valgo/varo após o treino, exceto uma pequena mudança (4° no valgo para o joelho esquerdo. CONCLUSÕES: O treino isocinético excêntrico dos extensores do joelho aumentou o torque extensor e diminuiu a razão I/Q, entretanto o efeito sobre o padrão da marcha parece desprezível em sujeitos saudáveis. Um treino associado dos flexores, complementar ao treino dos extensores parece ser necessário para o equilíbrio entre agonistas e antagonistas do joelho.

Buscamos enfatizar dois aspectos, entre tantos outros ainda por serem explorados na literatura científica do campo alimentar-nutricional: a hegemonia do paradigma biomédico e a fragmentação da vida humana quando campanhas publicitárias anunciam alimentos associando-os à ideia de alimentação saudável. Consideramos que não podemos viver somente como naquela publicidade onde nossos desejos são acionados, sem limites, onde mundo é só de sonhos e o objetivo principal é vender mais e lucrar mais, ainda que para isso se tenha feito uso de estratégias de disseminação de algumas informações de cunho biomédico-nutricional. O encontro entre alimentação e saúde, ou seja, alimentação saudável, deve pressupor, no nosso entendimento, a valorização da ação do sujeito, inclusive por meio de informações qualificadas e contextualizadas na vida social de modo a que se possa desenhar projetos de felicidade. Um sujeito fortalecido em sua identidade, íntegro e total que, entre sonhos e concretudes, pode ousar a buscar o conhecer e o pensar sobre si mesmo no mundo, sobre sua alimentação e sua saúde.In this essay we present some thoughts on advertising and a healthy diet in the contemporary world, where consumption plays a highly relevant role.

    Full Text Available In the Kingdom of Saudi Arabia (KSA, cardiovascular diseases (CVDs are the primary cause of death among adults, representing 46% of total mortality in 2014. This study’s objectives were to assess the prevalence of cardiovascular risk factors (CVRFs, and calculate the cardiovascular risk (CVR among King Saud University employees and their families. Moreover, it aimed at assessing the possible effects of living in KSA on the heart health of expatriate employees and their families. A cross-sectional study was conducted on 4500 university employees and their families aged ⩾18 years old, using the World Health Organization STEPwise approach to surveillance of CVRFs. CVR was then calculated for participants using the Framingham Coronary Heart Risk Score calculator. The mean age of participants was 39.3 ± 13.4 years. The prevalence of CVRFs was as follows: low fruit/vegetable consumption of 10% risk to develop CVD within the following 10-years. Furthermore, this study showed that expatriates had significant negative effects on behavioural risk factors after residing in KSA, namely: high rate of physical inactivity, high consumption of fast food, low consumption of fruit and vegetable. However, there was no effect on the pattern of tobacco use. The prevalence of CVRFs is substantially high among the study population. To combat the future expected burden of CVDs, a proposed prevention programme for employees’ cardiovascular wellness is designed and recommended to be implemented and institutionalized within the university.

The prevalence of CVRFs was as follows: low fruit/vegetable consumption of 10% risk to develop CVD within the following 10-years. Furthermore, this study showed that expatriates had significant negative effects on behavioural risk factors after residing in KSA, namely: high rate of physical inactivity, high consumption of fast food, low consumption of fruit and vegetable. However, there was no effect on the pattern of tobacco use. The prevalence of CVRFs is substantially high among the study population. To combat the future expected burden of CVDs, a proposed prevention programme for employees’ cardiovascular wellness is designed and recommended to be implemented and institutionalized within the university.

That is, the ideal gas equation of state is suitable for the Singular point and the universe. Maybe someone consider that, there is no vessel can accommodate radiation, it is because the Ordinary container is too small to accommodate, if the radius of your container is the distance that Light through an hour, would you still think it can't accommodates radiation? Modern scientific determinate that the radius of the universe now is about 1027 m, assuming that the universe is a sphere whose volume is approximately: V = 4.19 × 1081 cubic meters, the temperature radiation of the universe (cosmic microwave background radiation temperature of the universe, should be the closest the average temperature of the universe) T = 3.15k, radiation pressure P = 5 × 10-6 N / m 2, according to the law of ideal gas state equation, PV / T = constant = 6 × 1075, the value of this constant is the universe, The singular point should also equal to the constant Author: hanyongquan

    2013-03-01

    Full Text Available The model of the national university is being substituted by that of the global university. At the same time, new dogmas that appear with economic labels are being imposed. All this is accompanied by important cultural changes. The Spanish university was one of the instances that was taken care of by the post-Francoist regime. Now, this regime feels strong against it, and on the other hand this university – as the whole of the productive structure – requires a reform. It is not expected that this reform will go in the direction of the university having more social presence, but rather more presence of companies. It is neither expected that it will imply more internal democracy, but more discipline. All resistance or alternative has to take into account the new situation and join the still dispersed forces that still have, however, a constitutive capacity.

    1991-01-01

    'There is evidence to suggest that our world and everything in it - from snowflakes to maple trees to falling stars and spinning electrons - are only ghostly images, projections from a level of reality literally beyond both space and time.' This is the astonishing idea behind the holographic theory of the universe, pioneered by two eminent thinkers: physicist David Bohm, a former protege of Albert Einstein, and quantum physicist Karl Pribram. The holographic theory of the universe encompasses consciousness and reality as we know them, but can also explain such hitherto unexplained phenomena as telepathy, out-of-body experiences and even miraculous healing. In this remarkable book, Michael Talbot reveals the extraordinary depth and power of the holographic theory of the universe, illustrating how it makes sense of the entire range of experiences within our universe - and in other universes beyond our own.

    For a long time the question whether the universe rotates or not is discussed. Aspects of Huygens, Newton, Mach and other important historical scientists in this field are reported. The investigations of the mathematician Kurt Groedel in order to prove the rotation of the universe are illustrated. Kurt Groedel has shown that Einstein's gravitational equations of general relativity theory and the cosmological postulate of global homogeneity of cosmic matter (that is the Copernical principle) are not contradictionary to a rotating universe. Abberation measurements, position determination by means of radiointerferometry and methods for the determination of the rotation of the universe from the isotropy of the background radiation are presented. From these experiments it can be concluded that the universe seems not to rotate as already Einstein expected

  14. Age of the universe

    International Nuclear Information System (INIS)

    Parker, B.

    1981-01-01

    The age of the universe is the time that has elapsed since the Big Bang. To calculate the age, the expansion rate of the universe and distance to the galaxies must be determined. Unfortunately, it appears that the expansion rate is not constant but is decelerating. In the 1920's and 30's, Edwin Hubble set out to estimate the age of universe based on the expansion rate and distance to the galaxies. His method is described along with its flaw. Since that time several others have estimated the age of the universe. Their methods as well as results vary. These are discussed in the article. The ages determined from the various methods range from 10 to 20 billion years. There are two independent ways to determine the age of the universe. What they actually do is determine the age of our galaxy which would give a lower limit to the age of the universe. The first method calculates age of globular clusters which yields as age range from 8 to 18 billion years. The second method involves observing the speed at which radioactive substances decay. This also yields and age greater than 10 billion years. It is clear that there is still a lot of work to do before the true age of the universe can be determied

    A universal word for a finite alphabet $A$ and some integer $n\\geq 1$ is a word over $A$ such that every word in $A^n$ appears exactly once as a subword (cyclically or linearly). It is well-known and easy to prove that universal words exist for any $A$ and $n$. In this work we initiate the systematic study of universal partial words. These are words that in addition to the letters from $A$ may contain an arbitrary number of occurrences of a special `joker' symbol $\\Diamond\

The paper begins with an introduction that approaches the question from the viewpoint of ontic structural realism. Section 2 takes the case of the 'multiverse' of spatially homogeneous universes, and analyses the famous Collins-Hawking argument, which purports to show that our own universe is a very special member of this collection. Section 3 considers the multiverse of all solutions to the Einstein field equations, and continues the discussion of whether the notions of special and typical can be defined within such a collection.

  1. ULTRA: Universal Grammar as a Universal Parser.

    Science.gov (United States)

    Medeiros, David P

    2018-01-01

    A central concern of generative grammar is the relationship between hierarchy and word order, traditionally understood as two dimensions of a single syntactic representation. A related concern is directionality in the grammar. Traditional approaches posit process-neutral grammars, embodying knowledge of language, put to use with infinite facility both for production and comprehension. This has crystallized in the view of Merge as the central property of syntax, perhaps its only novel feature. A growing number of approaches explore grammars with different directionalities, often with more direct connections to performance mechanisms. This paper describes a novel model of universal grammar as a one-directional, universal parser. Mismatch between word order and interpretation order is pervasive in comprehension; in the present model, word order is language-particular and interpretation order (i.e., hierarchy) is universal. These orders are not two dimensions of a unified abstract object (e.g., precedence and dominance in a single tree); rather, both are temporal sequences, and UG is an invariant real-time procedure (based on Knuth's stack-sorting algorithm) transforming word order into hierarchical order. This shift in perspective has several desirable consequences. It collapses linearization, displacement, and composition into a single performance process. The architecture provides a novel source of brackets (labeled unambiguously and without search), which are understood not as part-whole constituency relations, but as storage and retrieval routines in parsing. It also explains why neutral word order within single syntactic cycles avoids 213-like permutations. The model identifies cycles as extended projections of lexical heads, grounding the notion of phase. This is achieved with a universal processor, dispensing with parameters. The empirical focus is word order in noun phrases. This domain provides some of the clearest evidence for 213-avoidance as a cross

    The problem of typicalness of the Universe - as a dynamical system possessing both regular and chaotic regions of positive measure of phase space, is raised and discussed. Two dynamical systems are considered: 1) The observed Universe as a hierarchy of systems of N graviting bodies; 2) (3+1)-manifold with matter evolving to Wheeler-DeWitt equation in superspace with Hawking boundary condition of compact metrics. It is shown that the observed Universe is typical. There is no unambiguous answer for the second system yet. If it is typical too then the same present state of the Universe could have been originated from an infinite number of different initial conditions the restoration of which is practically impossible at present. 35 refs.; 2 refs

    1982-01-01

    Is our universe an accident of nature. The mysterious coincidences underlying the structure and properties of the universe that we inhabit are examined. This is the first book for the non-specialist reader to present in depth the provocative hypothesis that the structure of the physical world is exceedingly contrived in its appearance. A survey is presented of the range of apparently miraculous accidents of nature that have enabled the universe to evolve its familiar structures: atoms, stars, galaxies, and life itself. This book concludes with an investigation of the so-called 'anthropic principle' which postulates that 'miraculous coincidences' are inevitable in any universe containing conscious observers. This thesis of a cosmic biological selection effect will both reassure and enrage readers, the very existence of whom may be related to fine tuning in the laws of physics. (author)

It is considered that the remarkable degree of isotropy, rather than the expansion, can be regarded as the central observational feature of the Universe. The various theories and ideas in 'big-bang' cosmology are discussed, providing an insight into current problems. Chapter headings are: quality of matter; expanding Universe; quality of radiation; quantity of matter; general theory of relativity; cosmological models; cosmological tests; matter and radiation; limits of isotropy; why is the Universe isotropic; singularities; evolution of structure.

    The approach to particle physics via cosmology may meet with an obstacle in a series of cosmological puzzles studied in this paper: the flatness-longevity puzzle, the horizon-homogenity puzzle, and the cosmological constant puzzle. An analysis of the geometry and dynamics of the universe leads to an understanding (but not solution) of the flatness-longevity puzzle: possible universes are distinguished by the value of the dimensionless quantity N, the coordinate density of ER particles, such that the longevity of the universe is fixed by N. Universes where nonrelativistic particles dominate are then studied. An inflationary scenario proposed as a solution to these puzzles is studied, but found to have some difficulties

The model proposed avoids the singularities of cosmologies of the Big Bang variety, it gives a good account of the redshifts, the cosmic background radiation, the number counts; it also gives a satisfactory explanation of the 'large numbers coincidence' and of the variation in time of fundamental constants.

    A review is made of some properties of the rotating Universe models. Godel's model is identified as a generalized filted model. Some properties of new solutions of the Einstein's equations, which are rotating non-stationary Universe models, are presented and analyzed. These models have the Godel's model as a particular case. Non-stationary cosmological models are found which are a generalization of the Godel's metrics in an analogous way in which Friedmann is to the Einstein's model. (L.C.) [pt

    From its unique vantage point 900 kilometres above the earth's surface, NASA's Cosmic Background Explorer (COBE) satellite has a privileged view of cosmic background radiation - the remnants of the early (radiation-dominated) Universe which followed the Big Bang some ten Gigayears ago, and possibly some subsequent history. In this way astroparticle physicists get a first peek at the quantum cosmology which moulded the infant Universe.

  2. Cultural universals: So what?

    Directory of Open Access Journals (Sweden)

    M. Elaine Botha

    1989-03-01

    Full Text Available The search for the elusive "cultural universal s” in a variety of academic disciplines has been motivated b y the spectre of relativism in its diverse guises. The problem of relativism has been thrust upon us inter alia by the inability of our epistemological models to account for social and cultural, moral and cognitive diversity and to provide us with criteria by means of which to judge aberrations like ideologies. Contrary to the general trend I would like to argue that it is not the spectre of relativism in its various guises which necessitates the search for cultural universals, nor is this the only motivation for a Christian to argue in favour of the recognition of cultural universals. Various authors have suggested that such universal structures do exist; that they condition human and societal behaviour and that it would in principle be possible to construct a theory of these structural universals or a "biogrammar" or "geography ” of the universal cultural acquisition device of humankind (cf. Harre,1976, 32; Johnson, 1987: xxxvii ; Tige r and Fox, 1974:17,30. Cross -cu ltural research in both psychology and anthropology has pointed to the existence of such traits, and in recent philosophical discussions Apel and others have pointed to the necessity of recognizing the existence of some sort of " transcendentalia" . These arguments emphasize elements that are common to diverse approaches to the problem of cultural universals. Christian scholars could accept most of these arguments as valid and yet argue in favour of a very specifically modified version of the notion of cultural universals. This essay attempts to develop such a position.

    The principal objectives of the Fossil Energy Program are to seek new ideas, new data, fundamental knowledge that will support the ongoing programs, and new processes to better utilize the nation's fossil energy resources with greater efficiency and environmental acceptability. Toward this end, the Department of Energy supports research projects conducted by universities and colleges to: Ensure a foundation for innovative technology through the use of the capabilities and talents in our academic institutions; provide an effective, two-way channel of communication between the Department of Energy and the academic community; and ensure that trained technical manpower is developed to carry out basic and applied research in support of DOE's mission. Fossil Energy's university activities emphasize the type of research that universities can do best - research to explore the potential of novel process concepts, develop innovative methods and materials for improving existing processes, and obtain fundamental information on the structure of coal and mechanisms of reactions of coal, shale oil, and other fossil energy sources. University programs are managed by different Fossil Energy technical groups; the individual projects are described in greater detail in this book. It is clear that a number of research areas related to the DOE Fossil Energy Program have been appropriate for university involvement, and that, with support from DOE, university scientific and technical expertise can be expected to continue to play a significant role in the advancement of fossil energy technology in the years to come.

  4. Universal Majorana thermoelectric noise

    Smirnov, Sergey

    2018-04-01

    Thermoelectric phenomena resulting from an interplay between particle flows induced by electric fields and temperature inhomogeneities are extremely insightful as a tool providing substantial knowledge about the microscopic structure of a given system. By tuning, e.g., parameters of a nanoscopic system coupled via tunneling mechanisms to two contacts, one may achieve various situations where the electric current induced by an external bias voltage competes with the electric current excited by the temperature difference of the two contacts. Even more exciting physics emerges when the system's electronic degrees freedom split to form Majorana fermions which make the thermoelectric dynamics universal. Here, we propose revealing these unique universal signatures of Majorana fermions in strongly nonequilibrium quantum dots via noise of the thermoelectric transport beyond linear response. It is demonstrated that whereas mean thermoelectric quantities are only universal at large-bias voltages, the noise of the electric current excited by an external bias voltage and the temperature difference of the contacts is universal at any bias voltage. We provide truly universal, i.e., independent of the system's parameters, thermoelectric ratios between nonlinear response coefficients of the noise and mean current at large-bias voltages where experiments may easily be performed to uniquely detect these truly universal Majorana thermoelectric signatures.

    Recognizing that the University Reactor Instrumentation Program was developed in response to widespread needs in the academic community for modernization and improvement of research and training reactors at institutions such as the University of Florida, the items proposed to be supported by this grant over its two year period have been selected as those most likely to reduce foreed outages, to meet regulatory concerns that had been expressed in recent years by Nuclear Regulatory Commission inspectors or to correct other facility problems and limitations. Department of Energy Grant Number DE-FG07-90ER129969 was provided to the University of Florida Training Reactor(UFTR) facility through the US Department of Energy's University Reactor Instrumentation Program. The original proposal submitted in February, 1990 requested support for UFTR facility instrumentation and equipment upgrades for seven items in the amount of $107,530 with $13,800 of this amount to be the subject of cost sharing by the University of Florida and $93,730 requested as support from the Department of Energy. A breakdown of the items requested and total cost for the proposed UFTR facility instrumentation and equipment improvements is presented

    As part of the World Year of Physics, the Physics Section of the University of Geneva is organising a series of conferences for the uninitiated. Each of the conferences will begin with a demonstration in the auditorium of the detection of cosmic rays and, in collaboration with Professor E. Ellberger of the Conservatoire de Musique de Genève, of how these signals from the farthest reaches of the Universe can be used to create "cosmic music". The third conference in the series, "How to build a universe?", will take place on Tuesday 15 March 2005 and the speaker will be the CERN theoretical physicist, John Ellis. A tiny number of elementary particles are responsible for the very diverse universe that surrounds us. These basic building blocks of matter interact by exchanging photons and other similar particles. After summing up what we know about these fundamental building blocks, their role in the history of the universe will be discussed. Where does matter come from? Where do the structures that ...

    1982-01-01

    General approach to the structure of the Universe is discussed. Two properties of physical laws: symmetry and changeability are considered from this view point. Each physical law permits simpler formulation in the notion of symmetry. But the simplicity of this description conceals interval mechanisms which make up the base of the physical law. The problem of physical law stability is analyzed. It is concluded that unrestricted changeability is the main property of physics. Primary attention is paid to the problem of ''quantum and Universe''. The effect of measuring process on the experimental results is the most difficult problem of quantum mechanisms. The quantum principle rejected an attempt to conceptually present the reality as it is pictured independently from its observation and it made the description of the Universe structure still more complicated and confused

    Full Text Available The barriers that women face to occupy the highest professional positions are well studied, yet they persist. The employment situation of women has improved, but the positions of power are still predominantly in male hands, as if men continually seek new mechanisms to keep, like viruses that change every year to survive the way vaccines. Barriers persist, although in recent decades women have managed to overcome in quantity and quality to men among university students. Women are still unable to access the best academic positions. Among university faculty only reach 40% and full professor position remain masculinized, having managed to reach the women -after many efforts and some policies- measures only 20%, which is seen clearly insufficient given their greater training. Against this background, the future is difficult, unless the university decided to endorse the cause of equality, going to assume its role of reference for the new generations and to other organizations and society in general.

  10. Baby universe theory

    1989-12-01

    We give an elementary review of the so called 'the theory of baby universes' which is a series of ideas or speculations about some effects in quantum gravity, viz. the effect of a certain type of wormholes, representing the exchange of small 3-space universes called baby universes. We consider this 'theory' as being physically and scientifically a very promising candidate for a theory of everything. It is, however, mathematically lacking any strong foundation at all. It solves several fine-tuning problems: First of all the cosmological constant problem, and also the strong CP-problem and the hierarchy problem. We also speculate that it might predict the possibility of influencing the probability distributions of the outcome of quantum mechanical measurements at one time by acts at a later time. (orig.)

  11. Phonology without universal grammar.

    Archangeli, Diana; Pulleyblank, Douglas

    2015-01-01

    The question of identifying the properties of language that are specific human linguistic abilities, i.e., Universal Grammar, lies at the center of linguistic research. This paper argues for a largely Emergent Grammar in phonology, taking as the starting point that memory, categorization, attention to frequency, and the creation of symbolic systems are all nonlinguistic characteristics of the human mind. The articulation patterns of American English rhotics illustrate categorization and systems; the distribution of vowels in Bantu vowel harmony uses frequencies of particular sequences to argue against Universal Grammar and in favor of Emergent Grammar; prefix allomorphy in Esimbi illustrates the Emergent symbolic system integrating phonological and morphological generalizations. The Esimbi case has been treated as an example of phonological opacity in a Universal Grammar account; the Emergent analysis resolves the pattern without opacity concerns.

    1979-01-01

    Following Gowdy and Berger we construct an inhomogeneous closed electromagnetic universe with three-torus topology. This model is obtained as a result of the homogeneity breaking in the electromagnetic Bianchi type-I universe and contains interacting gravitational and electromagnetic waves. This cosmological solution provides an exactly solvable model for the study of the nonlinear fully relativistic regime of coupled electromagnetic and gravitational fields in the early universe. The asymptotic behavior is considered (i) in the vicinity of the initial singularity and (ii) in the high-frequency limit. It is shown that the effects of coupling between electromagnetic and gravitational waves cause an evolution which is significantly different from that of the vacuum model. The influence of the primordial homogeneous electromagnetic field on the dynamics of the model is also discussed

    We introduce ``anamorphic'' cosmology, an approach for explaining the smoothness and flatness of the universe on large scales and the generation of a nearly scale-invariant spectrum of adiabatic density perturbations. The defining feature is a smoothing phase that acts like a contracting universe based on some Weyl frame-invariant criteria and an expanding universe based on other frame-invariant criteria. An advantage of the contracting aspects is that it is possible to avoid the multiverse and measure problems that arise in inflationary models. Unlike ekpyrotic models, anamorphic models can be constructed using only a single field and can generate a nearly scale-invariant spectrum of tensor perturbations. Anamorphic models also differ from pre-big bang and matter bounce models that do not explain the smoothness. We present some examples of cosmological models that incorporate an anamorphic smoothing phase.

    A new generalized solution of Maxwell-Einstein equations (which are non-minimally coupled) which leads to some fascinating aspects of the Universe is presented. The Cosmos has no singularity due to the coupling of longitudinal electromagnetism with space-time. It contains the Milne-Schucking cosmos as a limiting case. This model contains a free parameter (the longitudinal electromagnetic field) which allows one to fix the density of highest compression of the Cosmos. Alternativelly the parameter allows one to adjust our cosmos to the presently observed Hubble constant and the deceleration parameter. The model seems to be a viable candidate for our real cosmos as it allows one to extend the time scale of the Universe to arbitrarily large values i.e., it is able to provide the necessary time scale for the origin of life. It is speculated that the entropy is finite but intelligence in the Universe may be infinite. (Author) [pt

    We present a unified evolution of the universe from very early times until the present epoch by including both the leading local correction R2 and the leading non-local term R1□2R to the classical gravitational action. We find that the inflationary phase driven by R2 term gracefully exits...... in a transitory regime characterized by coherent oscillations of the Hubble parameter. The universe then naturally enters into a radiation dominated epoch followed by a matter dominated era. At sufficiently late times after radiation–matter equality, the non-local term starts to dominate inducing an accelerated...... expansion of the universe at the present epoch. We further exhibit the fact that both the leading local and non-local terms can be obtained within the covariant effective field theory of gravity. This scenario thus provides a unified picture of inflation and dark energy in a single framework by means...

    The purpose of this work was to obtain a broad knowledge of the circumstances under which activities involving ionizing radiations are held at brazilian academic institutions. Around 90 institutions (universities and isolated schools of both public and private sectors) were invited, by mail, to answer an inquiry with questions from technical to legal aspects of their activities with radiations. Information received from 2/3 of institutions contacted, permitted conclusions as: there is a wide ignorance about radioprotection procedures and legislation, although few universities maintain some efficient radioprotection staff; there is a need for the establishment of a standard radioprotection text dedicated to those specific activities of the sector.

Although the nature of both components is unknown, observational hints for their existence pile up but the direct detection of both has been unsuccessful so far. New ways have been explored to do without the concepts of dark matter and dark energy. This document that is divided into 3 parts presents the observational data that back the idea of dark matter and dark energy, the experimental effort made worldwide to detect dark matter particles, and the other ways to explain universe expansion

    Most models of the universe are dependent on the assumption of a uniform distribution of matter, and thus are rather crude, due to the nonlinear nature of Einstein's field equations. Here, a model is proposed which avoids this smoothing-out process. A metric is obtained which is consistent with the assumption that the matter of the universe is concentrated mainly in stars, moving with the velocity of recession implied by Hubble's law. The solution obtained gives results comparable to those obtainable by Schwarzchild metric, suitably adjusted to agree with the Einstein-DeSitter model at large distances

    The expectation of explaining cosmological observations without requiring new energy sources is forsooth worthy of investigation. In this Letter, a new kind of Cardassian models, called exponential Cardassian models, for the late-time universe are investigated in the context of the spatially flat FRW universe scenario. We fit the exponential Cardassian models to current type Ia supernovae data and find they are consistent with the observations. Furthermore, we point out that the equation-of-state parameter for the effective dark fluid component in exponential Cardassian models can naturally cross the cosmological constant divide w=-1 that observations favor mildly without introducing exotic material that destroy the weak energy condition

    We present a closed form expression for the semiclassical OPE coefficients that are universal for all 2D CFTs with a “weak” light spectrum, by taking the semiclassical limit of the fusion kernel. We match this with a properly regularized and normalized bulk action evaluated on a geometry with three conical defects, analytically continued in the deficit angles beyond the range for which a metric with positive signature exists. The analytically continued geometry has a codimension-one coordinate singularity surrounding the heaviest conical defect. This singularity becomes a horizon after Wick rotating to Lorentzian signature, suggesting a connection between universality and the existence of a horizon.

  6. The Classification of Universes

    International Nuclear Information System (INIS)

    Bjorken, J

    2004-01-01

    We define a universe as the contents of a spacetime box with comoving walls, large enough to contain essentially all phenomena that can be conceivably measured. The initial time is taken as the epoch when the lowest CMB modes undergo horizon crossing, and the final time taken when the wavelengths of CMB photons are comparable with the Hubble scale, i.e. with the nominal size of the universe. This allows the definition of a local ensemble of similarly constructed universes, using only modest extrapolations of the observed behavior of the cosmos. We then assume that further out in spacetime, similar universes can be constructed but containing different standard model parameters. Within this multiverse ensemble, it is assumed that the standard model parameters are strongly correlated with size, i.e. with the value of the inverse Hubble parameter at the final time, in a manner as previously suggested. This allows an estimate of the range of sizes which allow life as we know it, and invites a speculation regarding the most natural distribution of sizes. If small sizes are favored, this in turn allows some understanding of the hierarchy problems of particle physics. Subsequent sections of the paper explore other possible implications. In all cases, the approach is as bottoms up and as phenomenological as possible, and suggests that theories of the multiverse so constructed may in fact lay some claim of being scientific

    2018-01-15

    In this study, we consider nonlinear interactions between components such as dark energy, dark matter, matter and radiation in the framework of the Friedman-Robertson-Walker space-time and propose a simple interaction model based on the time evolution of the densities of these components. By using this model we show that these interactions can be given by Lotka-Volterra type equations. We numerically solve these coupling equations and show that interaction dynamics between dark energy-dark matter-matter or dark energy-dark matter-matter-radiation has a strange attractor for 0 > w de  >-1, w dm  ≥ 0, w m  ≥ 0 and w r  ≥ 0 values. These strange attractors with the positive Lyapunov exponent clearly show that chaotic dynamics appears in the time evolution of the densities. These results provide that the time evolution of the universe is chaotic. The present model may have potential to solve some of the cosmological problems such as the singularity, cosmic coincidence, big crunch, big rip, horizon, oscillation, the emergence of the galaxies, matter distribution and large-scale organization of the universe. The model also connects between dynamics of the competing species in biological systems and dynamics of the time evolution of the universe and offers a new perspective and a new different scenario for the universe evolution.

    Full Text Available Evidências científicas apontam que a saúde está relacionada ao modo de viver das pessoas e suas interações com o meio ambiente e não somente com a idéia hegemônica do determinismo biológico e genético. Nesse sentido, a habitação aparece como lócus base de Promoção da Saúde Familiar. O conceito de habitação saudável possui como ponto central a preocupação com o processo gradual de melhoria da qualidade de vida. O desafio está na consolidação da intervenção sobre os fatores determinantes da saúde no espaço construído, entendendo-os como biologia humana, meio ambiente e estilos de vida. Sendo estes fatores, na habitação, as principais causas de enfermidade e morte. Para enfrentar esse desafio é necessário articular as políticas públicas de habitação, de saúde, de ambiente e de infra-estrutura urbana e formar alianças intersetoriais, em uma visão holística, integradora e multidisciplinar. Portanto, o Programa Saúde da Família como estratégia de Promoção da Saúde em nível local passa a ser o ponto de intervenção e início de articulação entre as duas metodologias: Programa Saúde da Família e Habitação Saudável.Scientific evidences show that the health is linked with the way of people life and environment interactions. It is not only a genetic and biology determinism. In that way, housing is the basic locus of Family Health Promotion. Healthy house's conception has focused in improvement of quality of life. The challenge is around the strengthen of health specific understanding in built space as human biology, environment and life s. Those factors are the main cause of illness and death inside house. To face that challenge it's necessary to articulate public policy in housing, health, environment and urban infrastructure and in the way of intercessory alliances in holistic, integrated and multidisciplinary vision.

O presente estudo tem o propósito de conhecer as concepções desses profissionais sobre a alimentação saudável, com base na técnica metodológica da pesquisa-ação aplicada em centros de saúde do Distrito Federal. Os resultados mostram que existe um aparente dualismo entre os conceitos envolvidos nesse tema, um que versa sobre a idealização alimentar e outro que situa o espaço da realidade concreta dos indivíduos. Ou seja, há um conceito sobre a alimentação para a saúde fundamentado na literatura científica e outro que se apóia neste, mas distingue-se no espaço interno do cotidiano. Neste último, os atores sociais fazem correspondências entre um saber e outro e trazem à tona os hábitos alimentares conjugados ao estilo de vida, mas, em ambas as concepções, a tendência é transcender o caráter biológico implícito na construção do conceito e apoiar-se nas condições sócio-culturais que as moldam e são moldadas no plano concreto da realidade.Dietary changes in Western society highlight the need for individual and collective health providers to use their strategic positions to actively promote healthy eating habits.

Darker shades in the image on the left correspond to dimmer parts of the background glow, while yellow and white show the brightest light. Brief History of the Universe In figure 2, the artist's timeline chronicles the history of the universe, from its explosive beginning to its mature, present-day state. Our universe began in a tremendous explosion known as the Big Bang about 13.7 billion years ago (left side of strip). Observations by NASA's Cosmic Background Explorer and Wilkinson Anisotropy Microwave Probe revealed microwave light from this very early epoch, about 400,000 years after the Big Bang, providing strong evidence that our universe did blast into existence. Results from the Cosmic Background Explorer were honored with the 2006 Nobel Prize for Physics. A period of darkness ensued, until about a few hundred million years later, when the first objects flooded the universe with light. This first light is believed to have been captured in data from NASA's Spitzer Space Telescope. The light detected by Spitzer would have originated as visible and ultraviolet light, then stretched, or redshifted, to lower-energy infrared wavelengths during its long voyage to reach us across expanding space. The light detected by the Cosmic Background Explorer and the

    Turcan, Romeo V.; Gullieva, Valeria

    This paper explores a research gap at the intersection of university internationalization and university autonomy. A process model of university internationalization is put forward whereby the process of university internationalization is mediated by university internationalization capacity...... and moderated by target country institutional autonomy and globalization; and entry modes, timing and pace, as well as product mix of internationalization define university’s internationalization pattern. A systematic review is conducted to identify empirical studies at this intersection. One of the questions...

  14. The Artful Universe Expanded

    Barrow, John D.

    2005-07-01

    Our love of art, writes John Barrow, is the end product of millions of years of evolution. How we react to a beautiful painting or symphony draws upon instincts laid down long before humans existed. Now, in this enhanced edition of the highly popular The Artful Universe , Barrow further explores the close ties between our aesthetic appreciation and the basic nature of the Universe. Barrow argues that the laws of the Universe have imprinted themselves upon our thoughts and actions in subtle and unexpected ways. Why do we like certain types of art or music? What games and puzzles do we find challenging? Why do so many myths and legends have common elements? In this eclectic and entertaining survey, Barrow answers these questions and more as he explains how the landscape of the Universe has influenced the development of philosophy and mythology, and how millions of years of evolutionary history have fashioned our attraction to certain patterns of sound and color. Barrow casts the story of human creativity and thought in a fascinating light, considering such diverse topics as our instinct for language, the origins and uses of color in nature, why we divide time into intervals as we do, the sources of our appreciation of landscape painting, and whether computer-generated fractal art is really art. Drawing on a wide variety of examples, from the theological questions raised by St. Augustine and C.S. Lewis to the relationship between the pure math of Pythagoras and the music of the Beatles, The Artful Universe Expanded covers new ground and enters a wide-ranging debate about the meaning and significance of the links between art and science.

    We perform a state-of-the-art global fit to all Higgs data. We synthesise them into a 'universal' form, which allows to easily test any desired model. We apply the proposed methodology to extract from data the Higgs branching ratios, production cross sections, couplings and to analyse composite...... Higgs models, models with extra Higgs doublets, supersymmetry, extra particles in the loops, anomalous top couplings, and invisible Higgs decays into Dark Matter. Best fit regions lie around the Standard Model predictions and are well approximated by our 'universal' fit. Latest data exclude the dilaton...... as an alternative to the Higgs, and disfavour fits with negative Yukawa couplings. We derive for the first time the SM Higgs boson mass from the measured rates, rather than from the peak positions, obtaining M-h = 124.4 +/- 1.6 GeV....

  3. Universality of accelerating change

    Eliazar, Iddo; Shlesinger, Michael F.

    2018-03-01

    On large time scales the progress of human technology follows an exponential growth trend that is termed accelerating change. The exponential growth trend is commonly considered to be the amalgamated effect of consecutive technology revolutions - where the progress carried in by each technology revolution follows an S-curve, and where the aging of each technology revolution drives humanity to push for the next technology revolution. Thus, as a collective, mankind is the 'intelligent designer' of accelerating change. In this paper we establish that the exponential growth trend - and only this trend - emerges universally, on large time scales, from systems that combine together two elements: randomness and amalgamation. Hence, the universal generation of accelerating change can be attained by systems with no 'intelligent designer'.

    Full Text Available In this work, first, I reexamine the pyrocentric universe of the Pythagorean, Philolaus, who emphatically propounded that the center of the cosmos is neither the earth nor the sun, but a central fiery hearth that stands in the middle of the spherical universe. Second, I attempt to demonstrate the value and significance of this pyrocentric cosmic model by elaborating its novel revolutionary elements and its contribution to astronomy. Third, by underlining the diachroneity and timeliness of this cosmic model, I try to establish as to how the model served as a precursor to not only the ancient and modern heliocentric models, as widely believed, but also as much to the contemporary cosmic models and theories of astrophysics.

    Several recent works suggested the possibility of describing inflation by means of a renormalization group equation. In this paper we discuss the application of these methods to models of quintessence. In this framework a period of exponential expansion corresponds to the slow evolution of the scalar field in the neighborhood of a fixed point. A minimal set of universality classes for models of quintessence is defined and the transition from a matter dominated to quintessence dominated universe is studied. Models in which quintessence is non-minimally coupled with gravity are also discussed. We show that the formalism proves to be extremely convenient to describe quintessence and moreover we find that in most of the models discussed in this work quintessence naturally takes over ordinary matter.

  6. Improving University Research Value

    2012-07-01

    Full Text Available This article investigates the current data management practices of university researchers at an Intermountain West land-grant research university in the United States. Key findings suggest that researchers are primarily focused on the collection and housing of research data. However, additional research value exists within the other life cycle stages for research data—specifically in the stages of delivery and maintenance. These stages are where most new demands and requirements exist for data management plans and policies that are conditional for external grant funding; therefore, these findings expose a “gap” in current research practice. These findings should be of interest to academics and practitioners alike as findings highlight key management gaps in the life cycle of research data. This study also suggests a course of action for academic institutions to coalesce campus-wide assets to assist researchers in improving research value.

    In Woody Allen's masterpiece Annie Hall the main character is worried about the expansion of the universe. Indeed, during a childhood visit to his psychiatrist, his mother admonishes him: ''You're here in Brooklyn! Brooklyn is not expanding!''. But is that really true? Relativists have attacked this naive question many times and have arrived at different answers. New light has now been thrown on the subject by William Bonnor from Queen Mary and Westfield College in London by considering the influence of the expanding universe on the size of the hydrogen atom (Class. Quantum Grav. 1999 16 1313). According to Bonner's calculations we can conclude that the cosmic expansion does not affect human-scale objects like laboratories and our bodies. In this article the authors explain the reasoning behind this research and its thought provoking consequences. (UK)

    2004-01-01

    To observe or control a quantum system, one must interact with it via an interface. This article exhibits simple universal quantum interfaces--quantum input/output ports consisting of a single two-state system or quantum bit that interacts with the system to be observed or controlled. It is shown that under very general conditions the ability to observe and control the quantum bit on its own implies the ability to observe and control the system itself. The interface can also be used as a quantum communication channel, and multiple quantum systems can be connected by interfaces to become an efficient universal quantum computer. Experimental realizations are proposed, and implications for controllability, observability, and quantum information processing are explored

  9. Universal Test Facility

    A universal test facility (UTF) for Space Station Freedom is developed. In this context, universal means that the experimental rack design must be: automated, highly marketable, and able to perform diverse microgravity experiments according to NASA space station requirements. In order to fulfill these broad objectives, the facility's customers, and their respective requirements, are first defined. From these definitions, specific design goals and the scope of the first phase of this project are determined. An examination is first made into what types of research are most likely to make the UTF marketable. Based on our findings, the experiments for which the UTF would most likely be used included: protein crystal growth, hydroponics food growth, gas combustion, gallium arsenide crystal growth, microorganism development, and cell encapsulation. Therefore, the UTF is designed to fulfill all of the major requirements for the experiments listed above. The versatility of the design is achieved by taking advantage of the many overlapping requirements presented by these experiments.

    Maps of the galaxy distribution in the nearby universe reveal large coherent structures. The extent of the largest features is limited only by the size of the survey. Voids with a density typically 20 percent of the mean and with diameters of 5000 km s(-1) are present in every survey large enough to contain them. Many galaxies lie in thin sheet-like structures. The largest sheet detected so far is the "Great Wall" with a minimum extent of 60 h(-1) Mpc x 170 h(-1) Mpc, where h is the Hubble constant in units of 100 km s(-1) Mpc(-1). The frequent occurrence of these structures is one of several serious challenges to our current understanding of the origin and evolution of the large-scale distribution of matter in the universe.

    Most of the mass in the universe is in the form of dark matter—a new type of nonbaryonic particle not yet detected in the laboratory or in other detection experiments. The evidence for the existence of dark matter through its gravitational impact is clear in astronomical observations—from the early observations of the large motions of galaxies in clusters and the motions of stars and gas in galaxies, to observations of the large-scale structure in the universe, gravitational lensing, and the cosmic microwave background. The extensive data consistently show the dominance of dark matter and quantify its amount and distribution, assuming general relativity is valid. The data inform us that the dark matter is nonbaryonic, is “cold” (i.e., moves nonrelativistically in the early universe), and interacts only weakly with matter other than by gravity. The current Lambda cold dark matter cosmology—a simple (but strange) flat cold dark matter model dominated by a cosmological constant Lambda, with only six basic parameters (including the density of matter and of baryons, the initial mass fluctuations amplitude and its scale dependence, and the age of the universe and of the first stars)—fits remarkably well all the accumulated data. However, what is the dark matter? This is one of the most fundamental open questions in cosmology and particle physics. Its existence requires an extension of our current understanding of particle physics or otherwise point to a modification of gravity on cosmological scales. The exploration and ultimate detection of dark matter are led by experiments for direct and indirect detection of this yet mysterious particle. PMID:26417091

  1. Universe opacity and CMB

    Vavryčuk, Václav

    2018-04-01

    A cosmological model, in which the cosmic microwave background (CMB) is a thermal radiation of intergalactic dust instead of a relic radiation of the Big Bang, is revived and revisited. The model suggests that a virtually transparent local Universe becomes considerably opaque at redshifts z > 2 - 3. Such opacity is hardly to be detected in the Type Ia supernova data, but confirmed using quasar data. The opacity steeply increases with redshift because of a high proper density of intergalactic dust in the previous epochs. The temperature of intergalactic dust increases as (1 + z) and exactly compensates the change of wavelengths due to redshift, so that the dust radiation looks apparently like the radiation of the blackbody with a single temperature. The predicted dust temperature is TD = 2.776 K, which differs from the CMB temperature by 1.9% only, and the predicted ratio between the total CMB and EBL intensities is 13.4 which is close to 12.5 obtained from observations. The CMB temperature fluctuations are caused by EBL fluctuations produced by galaxy clusters and voids in the Universe. The polarization anomalies of the CMB correlated with temperature anisotropies are caused by the polarized thermal emission of needle-shaped conducting dust grains aligned by large-scale magnetic fields around clusters and voids. A strong decline of the luminosity density for z > 4 is interpreted as the result of high opacity of the Universe rather than of a decline of the global stellar mass density at high redshifts.

  2. The Flying University

    Science.gov (United States)

    Friesen, Catherine

    The Flying University is solo theater performance framed as an academic lecture about Marie Curie and her discovery of radium, delivered to a group of women who have gathered in secret to further their education. As the lecture proceeds, the professor brings in her own research based on a study of Esther Horsch (1905-1991) who lived on a farm in central Illinois. She introduces data from Esther's journals, personal memories, and dreams about Esther's life. The professor's investigation of radium plays at the intersections of magical and mundane, decay and the transformation of life, and the place of ambition in these two women's lives. The intention of this piece is to explore these themes, which are full of mystery, through the traces of the daily lives of Mme. Curie and Esther. Their words and photos are used as roots from which to imagine the things that echo beyond their familiar work; elemental and also fantastically radiant. The Flying University was written and performed by Catherine Friesen April 27-29, 2012 in the Center for Performance Experiment at Hamilton College as part of the University of South Carolina MFA Acting Class of 2013 showcase, Pieces of Eight.

  3. The inflationary universe

    International Nuclear Information System (INIS)

    Guth, A.; Steinhardt, P.

    1989-01-01

    The new inflationary cosmological model discussed here in terms of grand unified theories (GUTs) seems to offer solutions to all the problems associated with the big bang model, such as the existence of magnetic monopoles. Before the first 10 -30 s of the existence of the universe, a brief period of extraordinarily rapid expansion occurred according to the ''inflation'' model. Successes of the big bang model include the three standard testable predictions, but relate to time a second or two after the big bang, namely red-shifts of distant, receding galaxies, measured in the 1920s, the existence of a microwave background radiation, confirmed in 1964, and the abundance of light atomic nuclei such as Helium, Hydrogen and Lithium. Two problems posed by the big bang theory are the horizon problem which seeks an answer to the large-scale uniformity of the universe and the question of energy density which leads to questions about whether the universe is closed, open, or flat. In this new inflationary model the phase transition is driven by random fluctuations of the Higgs fields, thus overcoming the flaw in the original model. (U.K.)

    Electrogustometry is a method for taste diagnosis and measurement. The EG-2 project is being developed in cooperation between Warsaw University of Technology and Military institute of Medicine in Warsaw. The device is an evolution of the recent universal electrogustometer EG-1 prototype. Due to considerations and experiences acquired during prototype usage, many enhancements have been incorporated into device. The aim was to create an easy-to-use, portable, battery powered device, enabled for fast measurements. Developed electrogustometer is using innovative, low-power microprocessor system, which control whole device. User interface is based on 5.7" graphical LCD (Liquid Crystal Display) and touchscreen. It can be directly operated by finger or with optional stylus. Dedicated GUI (Graphical User Interface) offers simple, predefined measurements and advance settings of signal parameters. It is also possible to store measurements results and patients data in an internal memory. User interface is multilanguage. Signals for patients examinations, supplied with bipolar electrode, are generated by an on-board circuit using DDS (Direct-Digital Synthesis) and DAC (Digital-to-Analog Converter). Electrogustometer is able to generate DC, sinus, triangle or rectangle signals with current amplitude from 0 to 500 pA and frequency form 0 to 500 Hz. Device is designed for manual and automeasurement modes. By using USB (Universal Serial Bus) port it is possible to retrieve data stored in internal memory and charging of built-in Li-lon battery as a source of power.

  5. Universal elements of fragmentation

    International Nuclear Information System (INIS)

    Yanovsky, V. V.; Tur, A. V.; Kuklina, O. V.

    2010-01-01

    A fragmentation theory is proposed that explains the universal asymptotic behavior of the fragment-size distribution in the large-size range, based on simple physical principles. The basic principles of the theory are the total mass conservation in a fragmentation process and a balance condition for the energy expended in increasing the surface of fragments during their breakup. A flux-based approach is used that makes it possible to supplement the basic principles and develop a minimal theory of fragmentation. Such a supplementary principle is that of decreasing fragment-volume flux with increasing energy expended in fragmentation. It is shown that the behavior of the decreasing flux is directly related to the form of a power-law fragment-size distribution. The minimal theory is used to find universal asymptotic fragment-size distributions and to develop a natural physical classification of fragmentation models. A more general, nonlinear theory of strong fragmentation is also developed. It is demonstrated that solutions to a nonlinear kinetic equation consistent with both basic principles approach a universal asymptotic size distribution. Agreement between the predicted asymptotic fragment-size distributions and experimental observations is discussed.

  6. Antimatter in the universe

    International Nuclear Information System (INIS)

    Papini, P.; Spillantini, P.

    1996-01-01

    In this paper, the present knowledge on the study of antimatter in the universe is summarized. From the theoretical point of view, both baryon symmetric and asymmetric cosmologies are possible in the framework of big-bang theories. With the three 'Sakharov's conditions', it is possible to imagine an evolution from the big bang toward a universe with 'all matter' inside or toward a symmetric universe with matter and antimatter separated in domains. Measurement of the γ ray cosmic background implies only a local asymmetry and does not rule out the possibility of a symmetry on a large scale. Observations of the antiproton spectrum and antinuclei in cosmic rays are useful tools for studying the possible existence of an antigalaxy. The number and quality of the present data are poor, and no data are available at high energy, where the presence of an antigalaxy must be revealable owing to a large amount of antiprotons and antinuclei. In this paper, the future experimental projects to measure the antiproton flux at high energies and to search for antinuclei in cosmic rays are briefly presented

  14. The relational universe

    International Nuclear Information System (INIS)

    Magnon, A.

    1998-01-01

    A relational approach to be observable universe is proposed, which precludes the concept of absolute background. Space-time events emerge as dynamical entities which owe their existence to a memorization process, itself inter wind with the availability of cosmological horizons (screening from totality) sourcing long-range correlations. The resulting (and relational) mode of description sheds light on various paradoxes (EPR, Foucault pendolum, light beam effect, etc.), on the problem of instantaneous and global influences (quark deconfinement) as related to the interconnectedness of our cosmos. This scenario leads to comment on living systems vs. robots, and on non-recursive and global aspects of the mathematical intuition

    2005-01-01

    The cosmos is an awfully big place and there is no better guide to its vast expanse and fascinating nooks and crannies than John Barrow. A professor of mathematical sciences at Cambridge University, Barrow embodies that rare combination of highly polished writer and expert scientist. His deft touch brings together the disparate threads of human knowledge and weaves them into a tapestry as rich and interesting for the expert as it is for the layperson. The Artful Universe Expanded is an updated edition of this popular book first published in 1995. It explores the deeply profound manner in which natural law and the nature of the cosmos have moulded and shaped us, our cultures and the very form of our arts and music-a new type of 'cosmic' anthropology. The main themes Barrow chooses for revealing this new anthropology are the subjects of evolution, the size of things, the heavens and the nature of music. The book is a large, eclectic repository of knowledge often unavailable to the layperson, hidden in esoteric libraries around the world. It rivals The Da Vinci Code for entertainment value and insights, but this time it is Nature's code that is revealed. It is rare indeed to find common threads drawn through topics as diverse as The Beetles, Bach and Beethoven or between Jackson Pollock, the Aztecs, Kant, Picasso, Byzantine mosaics, uranium-235 and the helix nebula. Barrow unerringly binds them together, presenting them in a stimulating, conversational style that belies the amount of time that must have gone into researching this book. Dip into it at random, or read it from cover to cover, but do read it. The Artful Universe Expanded is an entertaining antidote to the oft-lamented pressures to know more and more about less and less and the apparently inexorable march of specialization. On reading this book one can, for a short time at least, hold in one's mind a vision that unifies science, art and culture and glimpse a universal tapestry of great beauty. (book review)

    This book presents a new approach to the subject of cosmology. It fully exploits Einstein's theory of general relativity. It is found that the most general formal expression of the theory replaces the (10-component) tensor formalism with a (16-component) quaternion formalism. This leads to a unified field theory, where one field incorporates gravitation and electromagnetism. The theory predicts an oscillating universe cosmology with a spiral configuration. Dark matter is explained in terms of a sea of particle-antiparticle pairs, each in a particular (derived) ground state. This leads to an ex

    Studies of the initial conditions for inflation have conflicting predictions from exponential suppression to inevitability. At the level of phase space, this conflict arises from the competing intuitions of CPT invariance and thermodynamics. After reviewing this conflict, we enlarge the ensemble beyond phase space to include scalar potential data. We show how this leads to an important contribution from inflection point inflation, enhancing the likelihood of inflation to a power law, 1/Ne3. In the process, we emphasize the attractor dynamics of the gravity-scalar system and the existence of universality classes from inflection point inflation. Finally, we comment on the predictivity of inflation in light of these results.

    The observation of the solar neutrinos and of a neutrino burst from the supernova explosion 1987A opened a new observation field which in the next years could be complemented with the detection of astrophysical highenergy neutrinos. Neutrino astronomy is a young discipline derived from the fundamental necessity of extending conventional astronomy beyond the usual electro-magnetic messengers. This is a summary of recent results on those new 'messengers of the universe', based on the presentations in Branch IV of the Neutrino Oscillation Workshop 2010 (NOW2010).

    A well-known difficulty associated with the conformal method for the solution of the general relativistic Hamiltonian constraint is the appearance of an aphysical ''bag of gold'' singularity at the nodal surface of the conformal factor. This happens whenever the background Ricci scalar is too large. Using a simple model, it is demonstrated that some of these singular solutions do have a physical meaning, and that these can be considered as initial data for Universe containing black holes, which are connected, in a conformally nonsingular way with each other. The relation between the ADM mass and the horizon area in this solution supports the cosmic censorship conjecture. (author)

    This paper presents a general stochastic model for procrastination with respect to a deadline. The model establishes a universal procrastination pattern that follows an inverse power-law: if the time remaining to the deadline is r then the response is 1/rε , where ɛ is a positive exponent. The model further establishes that the exponent value ε =1 , which yields the harmonic response 1/r , stands out as special and distinguishable. The theoretical results of the model are shown to be in perfect accord with recent empirical findings.

The first layer has resistivity values ranging from 44 Ω m–1200 Ω m with thickness ranging from 3 m to 18 m that is interpreted as the wadi deposits. The second layer having resistivity values from 11 Ω m to 137 Ω m is interpreted as the water saturated in the fractured basements. The third layer of resistivity values ranging from 2200 Ω m to 90,000 Ω m is interpreted as dry, massive basements. The GPR results provided internal images of the slab, showing its morphology, areas of possible damage and changes to the structure, and the situation of the steel reinforcements. It showed the presence of different shapes of fractures and voids with the growing of moisture zones.

The steganalytic model is trained by MHF-DZ steganographic algorithm previously designed by the same authors. The calibration technique with the Feature Based Steganalysis (FBS was employed in order to identify statistical changes caused by embedding a secret data into original image. The steganalyzer concept utilizes Support Vector Machine (SVM classification for training a model that is later used by the same steganalyzer in order to identify between a clean (cover and steganographic image. The aim of the paper was to analyze the variety in accuracy of detection results (ACR while detecting testing steganographic algorithms as F5, Outguess, Model Based Steganography without deblocking, JP Hide and Seek which represent the generally used steganographic tools. The comparison of four feature vectors with different lengths FBS (22, FBS (66 FBS(274 and FBS(285 shows promising results of proposed universal steganalytic method comparing to binary methods.

    Over the past few decades, NASA missions have revealed that we live in a Universe that is not a hydrogen-dominated, physicist's paradise, but in a molecular Universe with complex molecules directly interwoven into its fabric. These missions have shown that molecules are an abundant and important component of astronomical objects at all stages of their evolution and that they play a key role in many processes that dominate the structure and evolution of galaxies. Closer to home in our galaxy, the Milky Way, they have revealed a unique and complex organic inventory of regions of star and planet formation that may well represent some of the prebiotic roots to life. Astrobiology emerges from the great interest in understanding astrochemical evolution from simple to complex molecules, especially those with biogenic potential and the roles they may play as primordial seeds in the origin of life on habitable worlds. The first part of this talk will highlight how infrared spectroscopic studies of interstellar space, combined with dedicated laboratory simulations, have revealed the widespread presence of complex organics across deep space. The remainder of the presentation will focus on the evolution of these materials and astrobiology.

    The shape of fragments generated by the breakup of solids is central to a wide variety of problems ranging from the geomorphic evolution of boulders to the accumulation of space debris orbiting Earth. Although the statistics of the mass of fragments has been found to show a universal scaling behavior, the comprehensive characterization of fragment shapes still remained a fundamental challenge. We performed a thorough experimental study of the problem fragmenting various types of materials by slowly proceeding weathering and by rapid breakup due to explosion and hammering. We demonstrate that the shape of fragments obeys an astonishing universality having the same generic evolution with the fragment size irrespective of materials details and loading conditions. There exists a cutoff size below which fragments have an isotropic shape, however, as the size increases an exponential convergence is obtained to a unique elongated form. We show that a discrete stochastic model of fragmentation reproduces both the size and shape of fragments tuning only a single parameter which strengthens the general validity of the scaling laws. The dependence of the probability of the crack plan orientation on the linear extension of fragments proved to be essential for the shape selection mechanism.

    As the overall manager and integrator of International Space Station (ISS) science payloads, the Payload Operations Integration Center (POIC) at Marshall Space Flight Center has a critical need to provide an information management system for exchange and control of ISS payload files as well as to coordinate ISS payload related operational changes. The POIC's information management system has a fundamental requirement to provide secure operational access not only to users physically located at the POIC, but also to remote experimenters and International Partners physically located in different parts of the world. The Payload Information Management System (PIMS) is a ground-based electronic document configuration management and collaborative workflow system that was built to service the POIC's information management needs. This paper discusses the application components that comprise the PIMS system, the challenges that influenced its design and architecture, and the selected technologies it employs. This paper will also touch on the advantages of the architecture, details of the user interface, and lessons learned along the way to a successful deployment. With PIMS, a sophisticated software solution has been built that is not only universally accessible for POIC customer s information management needs, but also universally adaptable in implementation and application as a generalized information management system.

    Full Text Available A diminuição da força muscular com o envelhecimento e os baixos níveis de atividade física contribuem para défices funcionais e de equilíbrio. Esta revisão sistemática teve como objetivo analisar os estudos que correlacionaram o treino resistido (TR isolado, o equilíbrio e a função de idosos saudáveis. A busca nas bases do Google Acadêmico e na BVS levou à seleção de 35 estudos controlados. O TR isolado mostrou ser relevante para a função dos idosos (90% dos estudos devido sobretudo ao ganho de força e mobilidade. Exercícios de baixa e moderada intensidade tiveram melhores resultados sobre a função de idosas, frágeis e sedentários. Em relação ao equilíbrio, apesar da inconsistência dos dados, o TR parece exercer efeitos positivos, sobretudo devido a fatores neuromusculares. Estudos com parâmetros de treino e amostra uniformes são necessários para melhor comparação dos resultados, sobretudo em idosos com padrão funcional elevado.Muscle strength decrease in aging and low physical activity levels may be an indicator of balance deficits and functional limitations. The purpose of this systematic review was to assess the effects of resistance training (RT alone on balance performance and functional capacity in healthy elderly. The search in Google Scholar and BVS led to selecting 35 controlled trials. The RT alone showed to have positive effects (90% of the studies on functional tasks in elderly, associated with increases in strength and mobility. Moderate and low-intensity exercise could produce functional capacity benefits in older women, frail and sedentary elderly. Despite the inconsistency of data, resistance training appears to exert positive effects on balance, especially through neuromuscular factors. Standardization of methodology and homogeneity of sampling may ensure greater comparability of results, especially among elderly with high physical functional level.

  3. University autonomy as sensemaking

    DEFF Research Database (Denmark)

    Lind, Jonas Krog

    The formal autonomy of universities in Europe has generally increased over recent decades. However, new forms of accountability measures and more indirect state steering have accompanied this development, making it difficult to assess the actual autonomy. The article addresses this problem...... by applying the sensemaking approach to the study of organizational autonomy. Enacted autonomy is suggested as a new conceptualization that challenges the basic assumption in studies on formal autonomy that autonomy is only about external constraints on action. It does so by insisting on the active subjects...... in the enactment of the environment, thereby questioning the validity of a clear distinction between what is internal and what is external to an organization. By acknowledging the subjective dimension of autonomy, a set of stylized identities is developed as a tool for understanding the enactment of autonomy...

    Byrd, Mark S.; Lidar, Daniel A.; Wu, L.-A.; Zanardi, Paolo

    2005-01-01

    'Leakage' errors are particularly serious errors which couple states within a code subspace to states outside of that subspace, thus destroying the error protection benefit afforded by an encoded state. We generalize an earlier method for producing leakage elimination decoupling operations and examine the effects of the leakage eliminating operations on decoherence-free or noiseless subsystems which encode one logical, or protected qubit into three or four qubits. We find that by eliminating a large class of leakage errors, under some circumstances, we can create the conditions for a decoherence-free evolution. In other cases we identify a combined decoherence-free and quantum error correcting code which could eliminate errors in solid-state qubits with anisotropic exchange interaction Hamiltonians and enable universal quantum computing with only these interactions

  7. Universal mesoscopic conductance fluctuations

    Evangelou, S.N.

    1992-01-01

    The theory of conductance fluctuations in disordered metallic systems with size large compared to the mean free path of the electron but small compared to localization length is considered. It is demonstrates that fluctuations have an universal character and are due to repulsion between levels and spectral rigidity. The basic fluctuation measures for the energy spectrum in the mesoscopic regime of disordered systems are consistent with the Gaussian random matrix ensemble predictions. Although our disordered electron random matrix ensemble does not belong to the Gaussian ensemble the two ensembles turn out to be essentially similar. The level repulsion and the spectral rigidity found in nuclear spectra should also be observed in the metallic regime of Anderson localization. 7 refs. (orig.)

    Hannes Alfven has enjoyed a long and spectacular career in which he has time and again pioneered the path that other workers were able fruitfully to exploit. One thinks of the Alven waves, the concept of gyrocenter drift and the perturbation theory based on it, and the critical velocity phenomenon in the interaction of a plasma with a neutral gas. All of these discoveries have been of fundamental importance. By no means content to rest on his laurels, Alfven has, during the last decade, contributed to science in a major sense, especially in the field of cosmogeny. For example, he has used the latest data from the Voyager spacecraft to test his detailed predictions of the structure of the Saturnian rings. Alfven's current preoccupation is with the Plasma Universe and, as may be expected, some of his concepts are receiving observational support, while others are still controversial

    An alien invasion of CERN? Is there life elsewhere in the Universe? Are we alone? These questions have always fascinated humanity and for more than 30 years, physicists, biologists, chemists, cosmologists and astronomers have worked tirelessly to answer these questions. Yet just this past week at CERN students from all over Europe came to present their ideas on the subject and listen to the latest on extraterrestrial life from some of the world's most prestigious researchers. Students participating in the programme were encouraged to present their views on extraterrestrial life creatively and boy did they! The team from Portugal ran performances of Greek Theatre, the team from Hungary created a board game, while the team from Belgium recited poetry questioning the existence of extraterrestrials. But all was not light hearted, there were touching presentations of violin and piano by the French team and a very thought provoking theatre performance by the German team contrasting the search for extraterrestrial...

  13. Fred Hoyle's Universe

    Science.gov (United States)

    Gregory, Jane

    2005-08-01

    Fred Hoyle was a Yorkshire truant who became the voice of British astronomy. For fifty years, he spoke out for astronomy in the newspapers, on government committees, at scientific meetings, in popular books and on the radio. He devised a never-ending history of the universe, and worked out how the elements were made. He founded a prestigious institute for theoretical astronomy and built a giant telescope, and if it rained on his summer holiday, he sat in his caravan and wrote science fiction novels for his legions of fans around the world. Fred Hoyle also claimed that diseases fall from the sky, that the big bang never happened, and that the Astronomer Royal should be abolished. When the outspoken Fred Hoyle spoke out for astronomy, some astronomers really wished he had kept his mouth shut. This book tells the behind-the-scenes story of Hoyle's widely acclaimed and deeply controversial role in the ideas, organization and public face of astronomy in post-war Britain. It chronicles the triumphs, acrimony, jealousies, rewards and bitter feuds of a field in turmoil, and meets the astronomers, contemplating cosmic questions, keeping secrets, losing their tempers, winkling information out of distant stars and, over tea on the lawn, discussing the finer points of libel law. Fred Hoyle's Universe draws on previously confidential government documents, recently released personal correspondence and interviews with Hoyle's friends, colleagues and critics, as well as with Hoyle himself, to bring you the man, the science, and the scandal behind the genial and genteel facade of the most exciting period in the history of astronomy.

    We use the directed networks between articles of 24 Wikipedia language editions for producing the wikipedia ranking of world Universities (WRWU) using PageRank, 2DRank and CheiRank algorithms. This approach allows to incorporate various cultural views on world universities using the mathematical statistical analysis independent of cultural preferences. The Wikipedia ranking of top 100 universities provides about 60% overlap with the Shanghai university ranking demonstrating the reliable features of this approach. At the same time WRWU incorporates all knowledge accumulated at 24 Wikipedia editions giving stronger highlights for historically important universities leading to a different estimation of efficiency of world countries in university education. The historical development of university ranking is analyzed during ten centuries of their history.

  16. (Re)Discovering University Autonomy

    DEFF Research Database (Denmark)

    This book challenges traditional approach to university autonomy which is based on four pillars: organisational, financial, human resource, and academic. The main thesis is that a fuller understanding of university autonomy can only be obtained through a more holistic view of the complex inter......-relationships between stakeholders and policies which can reinforce and equally pull in opposite directions. The holistic view is expressed in a model of institutional university autonomy that brings together the traditional basic four pillars of autonomy, and five interfaces: government–university; university......–university staff; academic staff–students; university–business; and university–internationalisation. This model is explored through international case studies that give new insights and reinforce our understanding that the issues relating to institutional university autonomy are complex, interactive and genuinely...

Objetivo: desenhar, implementar e avaliar uma estraté-gia de intervenção para incrementar a disponibilidade de verduras numa comunidade de Tunja. Metodologia: estudo qualitativo em que foram aplicados os cinco princípios da pesquisa com base na comunidade. Incluidois componentes: educativo e agricultura urbana, que foram desenvolvidos em quatro fases: inserção na comunida-de, desenho, implementação e avaliação. Resultados: realizaram-se sete sessões educativas de tipo participativo e implementaram-se oito hortas caseiras e uma horta comunitária. Estes aspectos permitiram refetir a importância do consumo de verduras na alimentação diária. Conseguiu-se outorgar poder à comunidade, também a cons-trução de redes sociais e a visibilidade do papel do professional de enfermagem no campo comunitário. Discussão: esse projeto é um referente piloto ao nível local que contribui com a efetividade de processos educativos na cidade e em contextos semelhantes em torno ao tema da alimentação saudável. Conclusão: a estratégia de intervenção permitiu incrementar a disponibilidade de verduras, outorgar poder à comu-nidade, criar redes sociais e visibilizar o professional de enfer-magem a respeito do direcionamento e da liderança de ações comunitárias voltadas à promoção de estilos de vida saudáveis.Non-transmissible chronic diseases are a top priority as to public health, as they represent the main cause of disease and death worldwide, and specifically, in Tunja.

    Unless Ω>1,the Big Bang did not start from a point. Consideration shows sheet universes in which matter is confined to a homogeneous universe. Sheet universes and the corresponding embeddings of FRW universes into Minkowski space are drawn. Their initial singularities are shown to be point-like for the 'closed' case, line-like for the 'flat' (Ω=1) case and surface-like for the 'open' case. In contrast to the cross-sections at constant comoving proper time, typical spacelike cross-sections of the 'flat' universes are closed and encounter their extensive singularities. All cross-sections of the 'closed' universe are closed and only very special cross-sections encounter the point singularities at the Big Bang or the Big Crunch. (author)

    Full Text Available The utility of post-modernism as an interpretative framework for understanding the development of contemporary higher education systems is sharply contested. Critics argue that post-modernism is, at best, a set of ideas in aesthetics, literature and critical theory with limited relevance outside these domains and, at worst, a passing intellectual fashion that is now out-of-date. However, post-modernity —or, as some would prefer, late modernity or ‘fluid’ modernity — is perhaps a more useful idea. In 21stcentury society there are a number of trends, some structural such as the growth of a knowledge-based economy and development of new patterns of knowledge production; and some conceptual such as the reconfiguration of time and space and the recognition of ‘difference’ (and risk? as key factor in the constitution of social life (and individual identity, which have a direct impact on the university. This impact is felt in two ways — first, the university is a primary engine of these transformations. Secondly, the university is shaped by these transformations (both normatively and cognitively in terms of teaching and research and structurally in terms of its organisational characteristics, governance and managementLa utilidad del postmodernismo como marco interpretativo para comprender el desarrollo de los sistemas contemporáneos de educación superior ha sido severamente contestada. Los críticos argumentan que el postmodernismo es, como mucho, un conjunto de ideas en los ámbitos de la estética, literatura y teoría crítica con relevancia limitada fuera de esos campos y, a lo peor, una moda intelectual pasajera que actualmente está caducada. No obstante, la postmodernidad —o, como algunos preferirían, la modernidad tardía o modernidad «fluida»— es quizá una idea más útil.

    The philosophy of my life is to keep encouraging children to think beyond they could achieve easily. I understand children are adaptive to change and take things with an open mind. They are ready to experiment with new things and dare to dream big. I am fortunate to being a teacher by profession and thus I always attempt experimenting, observing, and participating with other children and adults. Children learn through play. From birth, children are active participants in building their own understanding. Teachers prepare the environment to help each child build on what they already know. It is such a great pleasure to observe every young kid that becomes excited and curious to know when we show them the Universe pictures and tell them about the strange objects in our Universe. So my aim is to keep them ignited by doing different activities throughout the year related to Space. I am always a firm believer of: Creativity is the key to success in the future, and primary education is where teachers can bring creativity in children at that level. One of my main ways of teaching is to conduct various presentations on The Solar System and beyond and debates on Space explorations. A Planet making project is one of the all-time favorite project for my students where they dare to dream to fly in the universe, and with their imagination, kids make different celestial objects and present them. To inculcate scientific attitude I arrange film screening, simulation exercises and quizzes on various topics of astronomy. Every year we celebrate World Space Week 4th to 10th of Oct. The motivation among all came through different hands-on activities like-painting, slogan competition, topics related to space, poetry and essay writing on various topics related to astronomy, assembly presentations in school. I am indeed overwhelmed when I started the very special Space and Astronomy club where young toddlers are involved in different activities like a star gazing program, conducting

METHOD: 50 newborns were studied. The Doppler parameters, peak-systolic velocity, end-diastolic velocity, mean velocity, pulsatility index and resistance index, were measured in the anterior cerebral artery, middle cerebral artery, posterior cerebral artery, and basilar artery. The data were compared and analyzed by statistical tests. Informed consent was obtained from all parents, and the study was approved by institutional ethical committee and review board. RESULTS: We observed not statistically significant differences on cerebral blood flow Doppler parameters in relation to type of delivery, sex, postnatal age and feeding in full term healthy newborns. CONCLUSION: We believe that the knowledge of these cerebral hemodynamic profile of newborns in the first days of life can contribute in an accurate interpretation of cranial Doppler abnormal findings when pathologic flow velocities are analyzed.OBJETIVO: O objetivo deste estudo foi avaliar com Doppler colorido a influência do tipo de parto, sexo, idade pós-natal e tempo pós-mamada no fluxo sanguíneo cerebral de recém-nascidos a termo e saudáveis.

    Born in Rome in 1901, Fermi was the last universal physicist - the most extraordinary of his century. He was at home in the workshop, the laboratory and among theoretical physicists. For the theorists he was a great theorist, and for the experimentalists he was a great experimentalist. What made Fermi so special as a physicist was his universality and versatility; what made him so special as a person was his modesty, realism and frugal lifestyle. This book, which describes Fermi's contributions to physics and the US period of his life, originated from a symposium that was held in Chicago in 2001 to commemorate the centenary of his birth. But it is not merely a volume of reminiscences. It combines essays, specially commissioned articles, as well as private material from Fermi's research notebooks, correspondence and speeches. Together the material highlights the breadth of his impact on physics. A classic biographical introduction by Emilio Segre is followed by an article in which Frank Wilczek, who shared the Nobel Prize for Physics last year, puts into perspective Fermi's huge contributions to physics. The list of his achievements is impressive. They include the introduction of Fermi statistics for half-integer-spin particles (1925) - now called fermions - that led to the concept of the 'Fermi surface' in condensed-matter and nuclear physics; the vector-coupling theory for beta-decay (1933), which formulated the proper structure of the weak interaction where the 'Fermi constant' measures the strength of the coupling; and the introduction, with his Rome group, of neutron-induced radioactivity and the study of slow-neutron interactions (1934). As a researcher and a teacher, Fermi inspired two generations and two continents - a man whose charismatic nature attracted many talented scientists and students to Chicago. What emerges from this book is the gratitude of so many extraordinary physicists to their master, who instilled in them

  6. Between universalism and regionalism: universal systematics from imperial Japan.

    Science.gov (United States)

    Lee, Jung

    2015-12-01

    Historiographic discussions of the universality and regionality of science have to date focused on European cases for making regional science universal. This paper presents a new perspective by moving beyond European origins and illuminating a non-European scientist's engagement with the universality and regionality of science. It will examine the case of the Japanese botanist Nakai Takenoshin (1882-1952), an internationally recognized authority on Korean flora based at Tokyo Imperial University. Serving on the International Committee on Botanical Nomenclature in 1926, Nakai endorsed and acted upon European claims of universal science, whilst simultaneously unsettling them with his regionally shaped systematics. Eventually he came to promote his own systematics, built regionally on Korean flora, as the new universal. By analysing his shifting claims in relation to those of other European and non-European botanists, this paper makes two arguments. First, universalism and regionalism were not contradictory foundations of scientific practice but useful tools used by this non-European botanist in maintaining his scientific authority as a representative Japanese systematist. Second, his claims to universality and regionalism were both imperially charged. An imperially monopolized study of Korean plants left a regional imprint on Nakai's systematics. In order to maintain his scientific authority beyond its region of origin he had to assert either the expanding regionalism of 'East Asia' or universalism.

  8. Water in the Universe

    2011-01-01

    Due to its specific chemical and physical properties, water is essential for life on Earth. And it is assumed that this would be the case for extraterrestrial life as well. Therefore it is important to investigate where water can be found in the Universe. Although there are places that are completely dry, places where the last rainfall happened probably several 100 million years ago, surprisingly this substance is quite omnipresent. In the outer solar system the large satellites of Jupiter and Saturn are covered by a thick layer of ice that could be hiding a liquid ocean below. This of course brings up the question of whether the recently detected extrasolar planets could have some water on their surfaces and how we can detect this. Water molecules are also found in interstellar gas and dust clouds. This book begins with an introductory chapter reviewing the physical and chemical properties of water. Then it illuminates the apparent connection between water and life. This is followed by chapters dealing with ...

    Full Text Available Economic globalization affects different countries on the globe, has positive effects mainly related to access to communication, which promotes the exchange of ideas, information, products and quality of life. However, extends numerous negative aspects such as marginalization, economic dependencies, political, cultural, scientific, educational accentuate social inequalities and cultural conflicts and territorial. In this article it is a dialogue with authors (Cunha 2009; BARNETT 2005; MORIN 1999, 2006, among others, who understand these changes in society from the contemporary world as conceived as the "Complexity era" or "supercomplexity". To understand and cope with this reality, they propose a paradigm that is able to overcome the fragmentation and reductionism of knowledge and to relate the multiple approaches and visions to meet the complexity of reality. Although this paper presents proposals to the aforementioned authors point to education and the university found in this tangle of interconnected global transformations, given the need to be subject to act in a complex reality that requires critical and self-critical professionals, able to think about their own ability to think, understand and act within this complex context.

    Prince, A. G.; Burg, J. A.

    The technology for the production, storage, transmission, and consumption of hydrogen as a fuel is surveyed, with the physical and chemical properties of hydrogen examined as they affect its use as a fuel. Sources of hydrogen production are described including synthesis from coal or natural gas, biomass conversion, thermochemical decomposition of water, and electrolysis of water, of these only electrolysis is considered economicially and technologically feasible in the near future. Methods of production of the large quantities of electricity required for the electrolysis of sea water are explored: fossil fuels, hydroelectric plants, nuclear fission, solar energy, wind power, geothermal energy, tidal power, wave motion, electrochemical concentration cells, and finally ocean thermal energy conversion (OTEC). The wind power and OTEC are considered in detail as the most feasible approaches. Techniques for transmission (by railcar or pipeline), storage (as liquid in underwater or underground tanks, as granular metal hydride, or as cryogenic liquid), and consumption (in fuel cells in conventional power plants, for home usage, for industrial furnaces, and for cars and aircraft) are analyzed. The safety problems of hydrogen as a universal fuel are discussed, noting that they are no greater than those for conventional fuels.

    Full Text Available Background. Bevacizumab (BEV, a humanized immunoglobulin G1 monoclonal antibody that inhibits VEGF has demonstrated activity against recurrent high-grade gliomas (HGG in phase II clinical trials. Patients and Methods. Data were collected from patients with recurrent HGG who initiated treatment with BEV outside a clinical trial protocol at two Belgian university hospitals. Results. 19 patients (11 M/8 F were administered a total of 138 cycles of BEV (median 4, range 1–31. Tumor response assessment by MRI was available for 15 patients; 2 complete responses and 3 partial responses for an objective response rate of 26% for the intent to treat population were observed on gadolinium-enhanced T1-weighted images; significant regressions on T2/FLAIR were documented in 10 out of 15 patients (67%. A reduced uptake on PET was documented in 3 out of 4 evaluable patients. The six-month progression-free survival was 21% (95% CI 2.7–39.5. Two patients had an ongoing tumor response and remained free from progression after 12 months of BEV treatment. Conclusions. The activity and tolerability of BEV were comparable to results from previous prospective phase II trials. Reduced uptake on PET suggests a metabolic response in addition to an antiangiogenic effect in some cases with favorable clinical outcome.

  16. Universal mechatronics coordinator

    Science.gov (United States)

    Muir, Patrick F.

    1999-11-01

    Mechatronic systems incorporate multiple actuators and sensor which must be properly coordinated to achieve the desired system functionality. Many mechatronic systems are designed as one-of-a-kind custom projects without consideration for facilitating future system or alterations and extensions to the current syste. Thus, subsequent changes to the system are slow, different, and costly. It has become apparent that manufacturing processes, and thus the mechatronics which embody them, need to be agile in order to more quickly and easily respond to changing customer demands or market pressures. To achieve agility, both the hardware and software of the system need to be designed such that the creation of new system and the alteration and extension of current system is fast and easy. This paper describes the design of a Universal Mechatronics Coordinator (UMC) which facilitates agile setup and changeover of coordination software for mechatronic systems. The UMC is capable of sequencing continuous and discrete actions that are programmed as stimulus-response pairs, as state machines, or a combination of the two. It facilitates the modular, reusable programing of continuous actions such as servo control algorithms, data collection code, and safety checking routines; and discrete actions such as reporting achieved states, and turning on/off binary devices. The UMC has been applied to the control of a z- theta assembly robot for the Minifactory project and is applicable to a spectrum of widely differing mechatronic systems.

    Full Text Available In the face of global competition and rising challenges that higher education institutions (HEIs meet, it is imperative to increase innovativeness and efficiency of their management. Benchmarking can be the appropriate tool to search for a point of reference necessary to assess institution’s competitive position and learn from the best in order to improve. The primary purpose of the paper is to present in-depth analysis of benchmarking application in HEIs worldwide. The study involves indicating premises of using benchmarking in HEIs. It also contains detailed examination of types, approaches and scope of benchmarking initiatives. The thorough insight of benchmarking applications enabled developing classification of benchmarking undertakings in HEIs. The paper includes review of the most recent benchmarking projects and relating them to the classification according to the elaborated criteria (geographical range, scope, type of data, subject, support and continuity. The presented examples were chosen in order to exemplify different approaches to benchmarking in higher education setting. The study was performed on the basis of the published reports from benchmarking projects, scientific literature and the experience of the author from the active participation in benchmarking projects. The paper concludes with recommendations for university managers undertaking benchmarking, derived on the basis of the conducted analysis.

  19. On universality in ergoregion mergers

    2009-01-01

    We study non-dynamical mergers of ergoregions in d + 1-dimensional vacuum gravity. At the merger point, where the ergosurfaces bounding each ergoregion just touch, solutions exhibit universal behavior when there is rotation only in one plane: the angle between the merging ergosurfaces depends only on the symmetries of the solution, not on any other details of the configuration. We show that universality follows from the fact that the relevant component of Einstein's equation reduces to Laplace's equation at the point of merger. Thus ergoregion mergers mimic mergers of Newtonian equipotentials and have similar universal behavior. For solutions with rotation in more than one plane, universality is lost. We demonstrate universality and non-universality in several explicit examples.

    In this Letter, we study the possibility of building a model of the oscillating universe with quintom matter in the framework of 4-dimensional Friedmann-Robertson-Walker background. Taking the two-scalar-field quintom model as an example, we find in the model parameter space there are five different types of solutions which correspond to: (I) a cyclic universe with the minimal and maximal values of the scale factor remaining the same in every cycle, (II) an oscillating universe with its minimal and maximal values of the scale factor increasing cycle by cycle, (III) an oscillating universe with its scale factor always increasing, (IV) an oscillating universe with its minimal and maximal values of the scale factor decreasing cycle by cycle, and (V) an oscillating universe with its scale factor always decreasing

    The boundary conditions to be imposed on the quantum state of the whole multiverse could be such that the universes would be created in entangled pairs. Then, interuniversal entanglement would provide us with a vacuum energy for each single universe that might be fitted with observational data, making testable not only the multiverse proposal but also the boundary conditions of the multiverse. Furthermore, the second law of the entanglement thermodynamics would enhance the expansion of the single universes.

    The Universe contains several billion neutrinos for each nucleon. In this paper, we follow the history of these relic neutrinos as the Universe expanded. At present, their typical velocity is a few hundred km/s and, therefore, their spectra are affected by gravitational forces. This may have led to a phenomenon that could explain two of todays great mysteries: The large-scale structure of the Universe and the increasing rate at which it expands. (paper)

    Full Text Available The dramatic expansion of Taiwan universities/colleges from about 100 to 160 from the late 1980s has encountered problems due to social and global changes. What should Taiwan universities move toward and how? This research relies on secondary data to explore the issues Taiwan universities currently face—a low birth rate and global competition. The decreasing number of incoming students will result in a lower registration rate and less tuition revenue, which will make some universities struggle to survive. Hence, government policies, proposed by the Ministry of Education, have been implemented to assist Taiwan universities to adjust to external changes. The Innovative Transformation Policy, adopted in 2015, consists of strategies for university–industry cooperation, university mergers, university closures, and a re-shaping of the university paradigm. This policy has begun to be implemented and its initial outcome will be continually evaluated. In accordance with the Innovative Transformation Policy, this study encourages Taiwan universities to improve governance, set prominent unique characteristics of development, and enhance global competitiveness.

    1990-01-01

    It is shown that the Bianchi 9 model universe satisfies the Mach principle. These closed rotating universes were previously thought to be counter-examples to the principle. The Mach principle is satisfied because the angular momentum of the rotating matter is compensated by the effective angular momentum of gravitational waves. A new formulation of the Mach principle is given that is based on the field theory interpretation of general relativity. Every closed universe with 3-sphere topology is shown to satisfy this formulation of the Mach principle. It is shown that the total angular momentum of the matter and gravitational waves in a closed 3-sphere topology universe is zero

    2009-01-01

    Electrogustometry has been used as a clinical tool for diagnosis and assessment of a variety of conditions. Since the lack of versatile electrogustometer for research and diagnosis, the new electrogustometer EG-1 was developed in 2006. It was done in cooperation between Warsaw University of Technology and Military Institute of Medicine in Warsaw. EG-1 allows quantitative estimation of taste perception threshold using both static and impulse electrogustometry with bipolar electrode. It is a fully autonomous, battery powered and portable instrument. Because of small size and weight, it can be easily placed in any environment. Microprocessor controlled measurement system and user-friendly interface (LCD display with simple keyboard) make EG-1 electrogustometer very handy and flexible in operation. Data obtained during measurements is stored in the internal device memory. After taste examinations measurement data can be transferred to a personal computer via inbuilt USB port for further analysis and storage. EG-1 can generate three predefined variously shaped current impulses: sinus-, saw- and rectangle-shaped. There is an optional possibility of creating own shapes of stimulus puls by the user. The electrical parameters of generated pulses are as follow: current amplitude 1-2000 microA regulated with 1 microA step, stimulus frequency 0(DC)-500 Hz regulated with 5 Hz step, controlable fulfillment factor and signal rise time (optional for automatic measurements). The operator can trigger the stimuli via a hand switch on the bipolar electrode (with gold-plated endings), via keyboard or via additional independent hand switch. Three years of experience collected during EG-1 exploitation allowed to design a new version of electrogustometer EG-2 with a touch panel and color graphical display.

  18. Baryogenesis in an inflationary universe

    International Nuclear Information System (INIS)

    Dodelson, S.

    1988-01-01

    The existence of matter in our universe today is a result of fundamental processes in the early universe. This matter is the remnant of an asymmetry between matter and anti-matter. How that asymmetry developed is the focus of this thesis. A statistical mechanical analysis is given of baryogenesis after an inflationary era

    In this paper we prove the universal nature of the Unruh effect in a general class of weakly nonlocal field theories. At the same time we solve the tension between two conflicting claims published in literature. Our universality statement is based on two independent computations based on the canonical formulation as well as path integral formulation of the quantum theory.

  20. Quantum entanglement of baby universes

    International Nuclear Information System (INIS)

    Aganagic, Mina; Okuda, Takuya; Ooguri, Hirosi

    2007-01-01

    We study quantum entanglements of baby universes which appear in non-perturbative corrections to the OSV formula for the entropy of extremal black holes in type IIA string theory compactified on the local Calabi-Yau manifold defined as a rank 2 vector bundle over an arbitrary genus G Riemann surface. This generalizes the result for G=1 in hep-th/0504221. Non-perturbative terms can be organized into a sum over contributions from baby universes, and the total wave-function is their coherent superposition in the third quantized Hilbert space. We find that half of the universes preserve one set of supercharges while the other half preserve a different set, making the total universe stable but non-BPS. The parent universe generates baby universes by brane/anti-brane pair creation, and baby universes are correlated by conservation of non-normalizable D-brane charges under the process. There are no other source of entanglement of baby universes, and all possible states are superposed with the equal weight

    1989-01-01

    In this paper some quantum effects of baby universes with induced gravity are discussed. It is proved that the interactions between the baby-parent universes are non-local, and argue that the induced low-energy cosmological constant is zero. This argument does not depend on the detail of the induced potential

    Full Text Available INTRODUÇÃO: A estimulação elétrica neuromuscular é uma estratégia clínica para aumento da performance muscular. Sabe-se que um dos principais fatores limitantes da estimulação elétrica para aumento de força é o desconforto causado pelas correntes utilizadas. OBJETIVO: O objetivo deste estudo foi comparar o nível de desconforto sensorial causado por correntes de baixa e média freqüência na estimulação elétrica neuromuscular do músculo quadríceps femoral. MÉTODOS: Participaram do estudo 45 voluntárias saudáveis com idade entre 18 e 30 anos. Todas as voluntárias foram submetidas à estimulação elétrica com correntes de baixa e média freqüência. A análise do desconforto sensorial foi feita por meio de uma escala visual analógica (EVA. RESULTADOS: Os resultados revelaram um valor médio de 6,1 para o desconforto sensorial na estimulação de baixa freqüência (BF e de 6,4 para a estimulação de média freqüência (MF, não havendo diferença estatisticamente significante entre elas (p = 0,61. Em relação às intensidades utilizadas, a média foi de 45,64mA para a estimulação de BF e 121,67mA na estimulação com a MF, sendo essa diferença estatisticamente significante (p INTRODUCTION: Neuromuscular electrical stimulation is a clinical strategy for increasing of muscular performance.

    Full Text Available Candida albicans oral strains collected from caries-free and caries-active healthy children ranging from 24 to 36 months old, were studied. The aim of the study was to determine proteinase and phospholipase activities produced by Candida albicans in the two groups and to determine the phenotypic diversity of these enzymes based on genetic polymorphism using the AP-PCR method. Strains identified by morphological and fermentation tests as C. albicans were grown in proteinase and phospholipase agar media at 37ºC for 7 and 4 days, respectively. After the incubation period, the enzyme activity of the proteinase and phospholipase positive strains was measured. All strains were subjected to AP-PCR, using the arbitrary primer AP-3. The enzymatic analysis showed no differences between the two groups. The AP-PCR method was effective in demonstrating intra-individual genetic polymorphism in C. albicans, showing a greater clonal diversity in caries-active versus caries-free children. Dendograms of similarity showed only intra-individual clonal lineage. The results suggest that the enzymatic profile does not depend on the genotypic characteristics of the strains.Cepas orais de Candida albicans coletadas de crianças saudáveis cárie ativas e livres de cárie com idade variando de 24 a 36 meses, foram estudadas. O propósito do estudo foi determinar a atividade da proteinase e da fosfolipase produzida por Candida albicans nos dois grupos e comparar com a diversidade genotípica usando o método AP-PCR. As cepas identificadas como C. albicans por testes morfológicos e de fermentação, foram cultivadas em meio ágar proteinase e fosfolipase a 37ºC por 7 e 4 dias, respectivamente. Após o período de incubação, a atividade enzimática das cepas proteinase e fosfolipase positiva foram medidas. Todas as cepas foram submetidas a técnica genotípica AP-PCR, usando o primer arbitrário AP-3. A análise enzimática demonstrou que não há diferença entre os

  20. A Model of Nonsingular Universe

    2012-07-01

    Full Text Available In the background of Friedmann–Robertson–Walker Universe, there exists Hawking radiation which comes from the cosmic apparent horizon due to quantum effect. Although the Hawking radiation on the late time evolution of the universe could be safely neglected, it plays an important role in the very early stage of the universe. In view of this point, we identify the temperature in the scalar field potential with the Hawking temperature of cosmic apparent horizon. Then we find a nonsingular universe sourced by the temperature-dependent scalar field. We find that the universe could be created from a de Sitter phase which has the Planck energy density. Thus the Big-Bang singularity is avoided.
