铜市凸现挤仓行情

最近3周，LME综合铜持续震荡整理，而沪铜走势则较为强劲。沪铜的这种走势是由什么因素推动的呢?虽然中国是铜的第一消费大国，在全球市场“中国因素”日益突出。但国内对铜的需求同样是增速趋缓。对铜需求较大的汽车行业在2月份大幅下滑，其产量环比和同比下滑了18％和23％。通常3月是建筑行业的开工旺季，但近期建筑用线材和螺纹钢的价格开始滞涨且有小幅回落，这反映了房地产开发商的谨慎心态，在面临金融政策等诸多不确定因素的情况下，建筑房地产业的扩张态势也有望适度缓解。

粮食仓内通风干燥的控制系统

仓内控制系统用于粮食的通风降温和粮食的自然通风及补热干燥的控制中。这两种控制的目的是不同的，因此分开讨论。1通风降温通风的主要目的是把在12－15％水分下贮存的粮食周围温度保持在3—6（”。通风的过程是以0.001－0．11m3／mint的流速让周围的空气吹过粮难。由一个通风控制器决定在什么时候通风和需要通风多长时间，最高级的可编程通风控制的需要测量周围空气的温度和相对湿度及粮食的温度和平衡柏对湿度。控制器使用了两个探查位置：一个是风机的进口；另一个是仓内粮食最容易升温和变质的位置。（即：空气气流最小的区域，仓中心…     

Parents’ knowledge,behaviour and concerns of food chemical hazards: Korean mothers sending their preschool‐aged children to child care centres

Although incidences of foodborne illness caused by chemical hazards are increasing, the studies on public awareness of food chemical hazards are limited. This study was conducted to assess mothers’ knowledge, behaviour and concerns on diverse food chemical hazards. A total of 960 mothers sending their preschool‐aged children to child care centres in Gwanak‐Gu, Seoul, Korea were surveyed, and 633 (65.9%) returned the questionnaires. After excluding inappropriate questionnaires, 364 (37.9%) were analysed. The majority of the mothers were able to identify food categories containing acrylamide (83.2%) and trans fat (80.2%), while slightly over half of the mothers named food categories containing allergen (56.3%) or pesticide residues (57.1%). Less than two thirds of mothers were knowledgeable of human exposure pathway to environmental contaminants (59.3%), acrylamide (55.2%) or heavy metals (65.9%). A significant number of mothers showed familiarity on health risk from dietary exposure to environmental contaminants (82.4%), trans fat (91.5%) or heavy metals (96.7%) (P < 0.05). The data on safe food behaviour towards environmental contaminants (81.8%), acrylamide (98.0%), heavy metals (96.7%) and trans fat (90.6%) showed high levels of right behaviours. About 47.2% and 22.8% of mothers read label of food additives and ingredient statement on allergen when purchasing processed foods, respectively. Mothers seemed to be concerned about food chemical hazards. Among the sociodemographic characteristics, only age significantly differentiated mothers’ concerns on chemical hazards in foods (P < 0.05). This study suggests that mothers needed to be educated on food chemical hazards regardless of their education levels, occupation status or the number of child.     

Clothing-related motorcycle injuries in Pakistan: findings from a surveillance study

This study aims to assess the burden and patterns of clothing-related motorcycle injuries in Karachi, Pakistan. Data were extracted from an ongoing traffic injury surveillance system. In three years (2007–2009), out of 99155 road traffic injury cases there were 986 (0.9%) cases of clothing-related motorcycle injuries. Most cases were females (73.9%) and pillion riders (80.6%). The crashes involving clothing-related injuries were mostly single vehicle (98.5%), and largely resulted in injuries to the external body (60.3%), limbs (51.0%), head (41.5%) and face (35.9%). One-third of injuries were either moderate (26.7%) or severe (10.2%) while 10 (1.01%) deaths were reported. Female gender (11.4%), age ≥ 45 years (19.4%), pillion riding (11.3%) and crashes occurring at intersections (12.3%) were more likely to result in moderate or severe injury as compared to other users (P < 0.001). Injuries due to entanglement of loose fitting clothing in motorcycles are not uncommon in Karachi. Awareness campaigns for prevention of such injuries may involve promotion of appropriate dressing for motorcycle riding including close wrapping of clothes and encouraging installations of covers on the rear wheels and drive chains.     

Factor allocation,economic growth and unbalanced regional development in China

On the basis of development accounting techniques and a factor misallocation framework, we use panel data of 30 Chinese provinces from 2000 to 2013 to assess how factor allocation affects economic growth and unbalanced regional development in China. In particular, we decompose economic growth into three parts, namely sector productivity (SP ), factor market efficiency (FME ) and factor endowment (FE ). We then conduct counterfactual analyses to investigate the short and long‐run roles of factor allocation in the income distribution across provinces. The results show that SP , FME and FE can explain 23%, 8.5% and 68.5% of economic growth, while labour, capital and energy reallocation account for aggregate productivity growth of about 47%, −4.8% and −0.1%. Furthermore, when the factors are efficiently allocated, transferring labour (capital, energy) from agriculture (service, industry) to the other sectors will increase the income per capita by 29.5% and 42.5% in the short and long term. Meanwhile, efficient factor allocation accounts for 32% and 29.7% of aggregate productivity and reduces the income variation across provinces by 25.5% and 23% in the short and long run, respectively.

Validity of parent's self-reported responses to home safety questions

The aim of the study was to describe the validity of parent's self-reported responses to questions on home safety practices for children of 2–4 years. A cross-sectional validation study compared parent's self-administered responses to items in the Home Injury Prevention Survey with home observations undertaken by trained researchers. The relationship between the questionnaire and observation results was assessed using percentage agreement, sensitivity, specificity, positive predictive value, negative predictive value and intraclass correlation coefficients. Percentage agreements ranged from 44% to 100% with 40 of the total 45 items scoring higher than 70%. Sensitivities ranged from 0% to 100%, with 27 items scoring at least 70%. Specificities also ranged from 0% to 100%, with 33 items scoring at least 70%. As such, the study identified a series of self-administered home safety questions that have sensitivities, specificities and predictive values sufficiently high to allow the information to be useful in research and injury prevention practice.     

Mortality due to injuries in Maputo City, Mozambique

Records of all registered deaths due to injuries maintained by the Legal Medicine Department in Maputo City for the period 1 January to 31 December 2000 were reviewed. Among the 1135 registered deaths, road traffic injuries accounted for the most common underlying cause of death (43.7%), followed by firearm discharge (8.7%) and burns (7.8%). For all deaths, skull fracture (21.9%), organ system injury (17.2%) and brain tissue injury (9.3%) were the most important intermediate causes of death and among the immediate causes of death acute anaemia (21.9%) was the most common followed by asphyxia (14.4%) and traumatic shock (12.0%). Overall, most cases were seen in the age group 20-29 years (27.0%) and comprising mainly males (male/female ratio 3.1). The most commonly reported cause for the victims to sustain injuries leading to death were accidents (59.4%), followed by homicides (19.8%), unknown causes (16.1%) and suicides (4.2%). Prevention of road traffic injuries and improved emergency care and health facility-based treatment is needed to reduce injury-related mortality.     

硫含量在出口航煤馏分中分布分析

采用紫外荧光法对切割后航煤各窄馏分油进行了硫含量的测定。结果表明：样品0%-0%窄馏分中硫含量只占整个馏分中硫含量的9.175%-10.451%,而80%-100%窄馏分中硫含量占整个馏分中硫含量的32.538%-45.326%,后者是前者的3.55-4.95倍;样品的平均硫含量与60%-80%窄馏分中硫含量数值接近。该结果对于了解和掌握出口航煤中硫含量在各窄馏分中的分布在数值上提供了依据。     

Pedestrians: the daily underestimated victims on the road

Traffic-related pedestrian injuries (TRPI) are vulnerable to road users. In this study, we aimed to evaluate the demographic pattern of injury and outcome of TRPI. Patients with TRPI admitted between November 2007 and March 2010 to the only level 1 trauma centre in Qatar were included. A retrospective analysis was based on medical records and Emergency Medical Services run sheets. The spreadsheet included demographic data and pre-hospital transport, service admissions and injuries by system and mortality. Of 4077 patients who were admitted, 420 (10.3%) had TRPI. The mode of transportation included ambulances (91%), private vehicles (6%) and helicopters (3%). The direct dispositions were trauma intensive care units (38%), surgical wards (42%) and operating rooms (17%). Patients were classified according to Injury Severity Score (1–8 in 28%, 9–15 in 25%, 16–24 in 20% and 25–75 in 17% cases). Multisystem injuries were most characteristic. Of 804 injures, injury of extremities was predominant followed by head, thorax and abdomen. The overall mortality was 8%. Pedestrian injuries are a significant cause of serious trauma in Qatar. Motor vehicle/pedestrian interface contributes to this ongoing public health problem. Reducing pedestrian trauma requires recognition of the problem and implementing programmes to mitigate these largely preventable injuries.

Driving under the influence of alcohol in Cali,Colombia: prevalence and consumption patterns, 2013

This study's goal was to establish the prevalence of driving under the influence of alcohol (DUI) and alcohol consumption patterns among drivers in Cali, Colombia, in 2013. A cross-sectional study based on a roadside survey using a stratified and multi-stage sampling design was developed. Thirty-two sites were chosen randomly for the selection of drivers who were then tested for blood alcohol concentration (BAC) and asked to participate in the survey. The prevalence of DUI was 0.88% (95% confidence intervals [95% CI] 0.26%–1.49%) with a lower prevalence when BAC was increasing. In addition, a higher prevalence was found during non-typical checkpoint hours (1.28, 95% CI ?0.001%–0.03%). The overall prevalence is considered high, given the low alcohol consumption and vehicles per capita. Prevention measures are needed to reduce DUI during non-typical checkpoints and ongoing studies are required to monitor the trends and enable the assessment of interventions.
