To investigate the effects of sudden change in wind loads on the running performance of trains on the bridge in crosswinds,a highway-railway one-story bridge was taken as the research object.Aerodynamic coefficients of the train and the bridge were measured in a series of train-bridge system segment models through wind tunnel tests when two trains passed each other on the bridge and when a train entered and left the wind barrier section of the bridge.Based on the improved SIMPACK and ANSYS rigid-flexible coupling simulation method,a wind-double train-track-bridge system coupled vibration model was established.The dynamic responses of the train were analyzed under the effects of sudden change in wind loads caused by two trains passing each other and a train entering and leaving the wind barrier section of the bridge.The results show that the effects of sudden wind load change caused by the trains passing each other had less effects on the running safety of the leeward-side train than the wind shielding effect caused by the windward-side train in the wind speed range of 10−25 m/s.With the decrease in the porosity of wind barriers,the effects of the sudden wind load change played an increasingly important role in the running safety and comfort of the train.With the increase in wind speed,the lateral response of the train increased obviously because of the effects of sudden wind load change,which affects both the lateral running stability and the comfort of the train. 展开更多

The 13th Five-year Plan period (2016-2020) is a crucial period for environmental protection in China and represents the last chance for the achievement of the environmental objective under the goal of building a well-off society in an all-round manner. During this period of time, China' s environment is confronted with the following major risks: risks of environmental quality, human health, ecological security, balanced regional development and international influence. The overall conclusion is that the tendencies of changing eco-environment are complex, problems remain outstanding, and some risks have abated while others have intensified with possible improvements in the future. Future prospects mainly depend on the intensity of actions taken. It is suggested that environmental protection strategy of"overall optimization" be adopted for the 13th Five-year Plan period, i.e. environmental protection requirements should be incorporated into political, economic, social and cultural spheres, so that these areas with major influence on the natural environment will improve and transform towards an environmentally friendly direction and ultimately help achieve the objective of improving eco-environment and people's welfare. In order to fundamentally reverse mainstream understanding on environmental protection, it is suggested to define the "contradiction between environmental pressures arising from growing economic development and China ' s limited and fragile environmental capacity" as a major contradiction of Chinese society. 展开更多

Objective Cardiovascular complications contribute to postoperative morbidity and mortality in elderly hip fracture patients. Limited data are available regarding which preoperative risk factors predict cardiovascular course following hip fracture surgery (HFS). We used high sensitive troponin I (hs-TnI) assays and clinical parameters to identify preoperative risk factors associated with major adverse cardiac events (MACE) in elderly hip frac^u'e patients. Method From August 2014 to November 2016, 575 patients with hip fracture were enrolled in a retrospective, single-center registry. A total of 262 of these patients underwent HFS and hs-TnI assays. MACE was defined as postoperative all-cause deaths, heart failure (HF), new-onset atrial fibrillation (AF), myocardial infarction (MI) and cardiovascular re-hospitalization that occurred within 90 days postoperative. Results Of 262 HFS patients, MACE developed following HFS in 65 (24.8%). Patients with MACE were older and had higher rates of renal insufficiency, coronary artery disease, prior HF, low left ventricular ejection fraction and use of beta blockers; higher levels of hs-Tnl and N-terminal pro-brain natriuretic peptide (NT-proBNP) and higher revised cardiac risk index. A preoperative hs-TnI≥ 6.5 ng/L was associated with high risk of postoperative HF, new-onset AF and MACE. In multivariable analysis, pre-operative independent predictors for MACE were age 〉 80 years [adjusted hazard ratio (HR): 1.79, 95% confident interval (CI): 1.03-3.13, P = 0.04], left ventricular ejection fraction (LVEF) 〈 50% (adjusted HR: 3.17, 95% CI: 1.47-5.82, P 〈 0.01) and hs-TnI 〉 6.5 ng/L (adjusted HR: 3.75, 95% CI: 2.09~5.17, P 〈 0.01). Conclusion In elderly patients with hip fracture who undergo HFS, a preoperative assessment of hs-TnI may help the risk refinement of cardiovascular complications. 展开更多

Since children, as a rule, have more free time than adults, it is adults' responsibility to provide children with a chance to spend the time of relaxation, play, and fun in a beneficial way. Unfortunately, children's spare time is nowadays very frequently organized for the sake of brushing up children's knowledge, skills, and competences, which is accomplished by means of escalating extra-curriculum activities. When expressed by teacher and parents, these ambition-related attitudes pave the way for the disappearance of children's personal interests and motivations to perform complicated tasks which are perceived as unwanted or obscure by the affected children themselves. This form of adults' behavior may lead to the feelings of frustration, stress, demotivation, or rebellion on behalf of their children. The said emotional states, especially in relation to the lack of spontaneous play, give rise to serious psychic dysfunctions, and the instability of children's psychic balance. It may also pave the way for various forms of destructive behavior that mostly characterize children of younger school age who are about to start schooling. 展开更多

The relationship between the self-organization of double vortices (SODVs) and the formation of typhoons was discussed based on six numerical experiments with the Fifth-Generation National Center for Atmospheric Research/Penn State Mesoscale Model (MM5) and further discussion was made with a real typhoon case. The results showed that there is a critical distance dc for SODVs in baroclinic atmosphere. When the distance between separated vortices is smaller than or equal to d~, the double vortices self-organize into a typhoon-like vortex with two spiral bands. But the double vortices cannot have such organization if the distance between them is larger than de. The value of dc is about 380 km in the context of ideal conditions in this paper, larger than that achieved in a barotropic model. A typical typhoon case in 2005 (Haitang) was selected to verify the above-mentioned conclusions. It was found that the SODV is one of the important and typical ways for the formation of typhoons. 展开更多

The Pyrenean chamois Rupicapra pyrenaica pyrenaica is a mountain-dwelling ungulate with an extensive presence in open areas. Optimal group size results from the trade off between advantages (a reduction in the risk of predation) and disadvantages (competition between members of the herd) of group living. In addition, advantages and disadvantages of group living may vary depending on the position of each individual within the herd. Our objective was to study the effect of central vs. peripheral position in the herd on feeding and vigilance behavior in male and female Pyrenean chamois and to ascertain if a group size effect existed. We used focal animal sampling and recorded social interactions when a focal animal was involved. With males, vigilance rate was higher in the central part of the group than at the periphery, probably due to a higher density of animals in the central part of the herd and a higher probability of being disturbed by conspecifics. With females, vigilance rate did not differ according to position in the herd. Females spent more time feeding than males, and males showed a higher frequency of the vigilance behavior than females. We did not observe a clear relationship between group size and vigilance behavior. The differences in vigilance behavior might be due to social interactions 展开更多

Using semiotic and discourse analysis methodologies to uncover denotative and connotative meanings in journalism production, following Roland Barthes's work, our research analyzed newspaper humour published in one Portuguese newspaper about the global build-up of the swine flu (H1N1) scare of 2009-2010. Results demonstrate that humour was much quicker than traditional journalistic templates to assign responsibilities and depict failures in the crisis management system, precociously suggesting that the pandemic could be just another moral panic similar to the bird flu of 2005. Through humour, newspapers stressed the cyclic nature of health risks, reducing the impact of dramatic information on the audience. It is therefore suggested that the sociological analysis of a media outlet in the context of a complex and emotional case such as the 2009-2010 pandemic implies its deconstruction layer by layer in order to obtain a clear picture of the mechanisms of social construction of reality. 展开更多

With the rising of the Empire, 18th century Britain went through significant changes. Politics and economy in tandem with people's mobility led to the emergence of new and faster ways of climbing the social ladder, shaping new social groups with newly acquired needs, that is, with lifestyles quite distinct from the previously known ones. The colonies with their increasing commercial activities and their equally growing administration created innumerable jobs, some of which proved to be very profitable indeed. People from all walks of life, from either the working class or to the aristocracy, tried their luck crossing the Atlantic to start a whole new life. After the loss of the American colonies, it fell on the South Asia dominions, i.e., India, to play the role of the land of opportunity. After the Battle of Plassey (1757) and of Buxar (1764), the East India Company was politically empowered. India was in those days seen as a land of great potential: By either means of legitimate or corrupt business, one could possibly become immensely rich in a short time. These nouveau-riches, the so called "nabobs," also adopted many shadings of authoritarianism and ostentation thought to be common among oriental leaders; the nawabs, they were called after. Once back in Great Britain, their manners, or the lack of them, and their display of wealth upset British public opinion some much that, as was to be expected, it resulted on their becoming the object of ridicule and ostracism in periodicals, theatre plays, poems, caricatures... Nevertheless, they actively contributed to structural changes in the meaning and uses of wealth, interfered in politics and inter-class relationships, created more jobs, and were keen on experimenting new methods either in agriculture, building, or industry. This paper, though acknowledging these relevant consequences, aims at highlighting their impact on the sphere of aesthetics. The forms and textures, the motives, and the colors they adopted in their clothing, their jewelry, as well as in their architectural projects brought forth a kind of flamboyant baroque. According to Deleuze's notion of the baroque (The Fold. Leibniz and the Baroque, 1993), the assertion that the nabobs unfolded new, more colourful urban and rural landscapes is certainly possible to sustain. Marian Hastings, second wife to Warren Hastings, the first de facto Governor-General of India from 1773 to 1785, was considered the epitome of the "nabobina," a feminine nabob. So, the ensuing paper will focus on her description in Eliza Ryves's satirical poem The Hastiniad, comparing it with some factual data about Marian Hastings's style, and the Hastings couple's home at Daylesford, Gloucestershire. 展开更多

In this paper a comprehensive review is presented of risk assessment techniques adopted in the mining industry worldwide;those techniques applied in other hazardous industries and potential techniques which are robust,mature and holistic and can be implemented for the Indian mining industry in future to enhance workplace safety are also presented.Findings from the review are indicative of the fact that socio-technical complexity of industrial systems has increased.Recent developments in the area of risk management highlight the need for implementation of the latest robust techniques of risk assessment in the mining sector.In consideration of the present scenario,the development of a model for risk analysis having an interface between hazard identification and risk assessment,along with an interface between risk assessment and accident causation to predict if an accident will occur under given conditions,has become dire necessity.This will increase hazard awareness and enable mine management to select and prioritize problem areas and identify safety system weaknesses in both underground and surface mining.This will ultimately help decision makers,risk analysts and safety managers make a major contribution in the development of workplace safety with a near-to-zero accident rate. 展开更多

A key solution to urban and global sustainability is effective planning of sustainable urban development, for which geo-techniques especially cellular automata(CA) models can be very informative. However, existing CA models for simulating sustainable urban development, though increasingly refined in modeling urban growth, capture mostly the environmental aspect of sustainability. In this study, an adaptable risk-constrained CA model was developed by incorporating the social-ecological risks of urban development. A three-dimensional risk assessment framework was proposed that explicitly considers the environmental constraints on, system resilience to, and potential impacts of urban development. The risk-constrained model was then applied to a case study of Sheyang County, Jiangsu Province in the eastern China. Comparative simulations of urban development in four contrasting scenarios were conducted, namely, the environmental suitability constrained scenario, the ecological risk constrained scenario, the social risk constrained scenario, and the integrated social-ecological risk constrained scenario. The simulations suggested that considering only environmental suitability in the CA simulation of urban development overestimated the potential of sustainable urban growth, and that the urbanization mode changed from city expansion that was more constrained by social risks to town growth that was more constrained by ecological risks. Our risk-constrained CA model can better simulate sustainable urban development; additionally, we provide suggestions on the sustainable urban development in Sheyang and on future model development. 展开更多

The theme of trafficking of human beings treats one of the most severe and dangerous criminal phenomena of the organized crime in Albania. The objects of this paper are: human trafficking; ways of trafficking; risk of Albanian society; and investment of the criminal benefits deriving from trafficking in legal economic activities, it is of great importance for the treatment of proactive investigations to the trafficking of human beings. Another important aspect of the trafficking investigations is the investigation of criminal assets and the way how they are used in the economy of the country. In this paper, we stress that the investigation of criminal assets benefited by the crime of trafficking human beings as well as other wealth financed by these assets is important as the investigation of the criminal activity of trafficking itself. Also, we aim to evaluate the necessity of acting of all law enforcement agencies and other state institutions in order to be successful in the fight against the crime of trafficking of human beings. At the end of this paper, we do treat the necessity and the ways of collaboration of law enforcement agencies, NGOs, and structures of local government for rehabilitation of the victims of trafficking and their integration in the social life. 展开更多

Two trains passing each other is controlling factor for the wind-vehicle-bridge systems.To test the aerodynamic characteristics of moving vehicles under crosswinds when two trains are passing each other,a wind tunnel test device,which has two moving tracks,was developed.The rationality of the test result was discussed,the effects of intersection mode,yaw angle and lane spacing on the aerodynamic coefficients of the leeward train were analyzed,and the difference of aerodynamic coefficients between the head vehicle and the tail vehicle was discussed.The results show that the proposed test device has good repeatability.The intersection modes have a certain effect on the aerodynamic force of the leeward train when two trains are passing each other,and the results should be more reasonable during the two trains dynamic passing each other.With the decrease of yaw angle,the sudden change of train aerodynamic coefficients is more obvious.The decrease of lane spacing will increase the sudden change of leeward vehicles.In the process of two trains passing each other,the aerodynamic coefficients of the head vehicle and tail vehicle are significantly different,so the coupling vibration analysis of wind-vehicle-bridge system should be considered separately. 展开更多

METHODS:We identified the studies using PubMed. Studies were selected for analysis based on certain inclusion and exclusion criteria.Data were extracted from each study on the basis of predefined items.Metaanalyses were performed to verify the risk factors,such as obesity and gender. RESULTS:Twenty-one studies were included in this systematic review.These studies demonstrated an association between increasing BMI and the presence of EE[95%confidence interval(CI):1.35-1.88,overweight,odds ratio(OR)=1.60,P value homogeneity =0.003,95%CI:1.65-2.55,obese,OR=2.05,P< 0.01].The heterogeneity disappeared by stratifying for gender.No publication bias was observed in this metaanalysis by the Egger method. CONCLUSION:This analysis demonstrates a positive association between BMI and the presence of EE,especially in males.The risk seems to progressively increase with increasing weight. 展开更多
