The Poyang Lake is the largest fresh water lake in China, of which the vast area is about 39955 km. The Poyang Lake Area, on the other hand, is the place where floods often occur. In order to reduce the impact and damage of floods on the lives and properties of people living in the Poyang Lake Area, the authors have developed a Geographical Information System for preventing and controlling floo...

The activities of six fluoroquinolones were determined for 117 separate strains of Shigella sonnei. The order of increasing activity (MICs for 90% of strains tested) was enoxacin (0.25 micrograms/ml), temafloxacin (0.032 micrograms/ml), sparfloxacin (0.016 micrograms/ml), CI-960 (0.008 micrograms/ml), ciprofloxacin (0.008 micrograms/ml), and PD-131628-2 (0.008 micrograms/ml). These data, along ...

Noroviruses are now recognized as the major cause of acute gastroenteritis in the developed world, yet our ability to prevent and control infection is limited. Recent work has highlighted that, while typically an acute infection in the population, immunocompromised patients often experience long-term infections that may last many years. This cohort of patients and those regularly exposed to inf...

The influence of number of autoclave treatment cycles (N) on rotational speed and total indicated run-out of commercially available air-turbine handpieces from five manufacturers was investigated at N=0, 50, 100, 150, 200, 250 and 300 cycles, and the significance in the test results was assessed by Dunnett's multiple comparison test. Some air-turbine handpieces showed the significant difference...

Streaming content will account for 91% of all global consumer Internet traffic by 2013. There is an increasing demand for video streams with high perceptual quality. The capability of present day Internet links in delivering high perceptual quality streaming services, however, is not completely understood. Link level degradations caused by intra-domain routing policies and inter-ISP peering pol...

The rapid expansion of wind farms has drawn attention to operations and maintenance issues. Condition monitoring solutions have been developed to detect and diagnose abnormalities of various wind turbine subsystems with the goal of reducing operations and maintenance costs. This paper explores fault data provided by the supervisory control and data acquisition system and offers fault prediction...

OBJECTIVE To evaluate effectiveness of a community-based preparedness program for flash floods. DESIGN A controlled community intervention trial with preassessment and postassessment. SETTING Fifteen intervention villages and 16 control villages in Golestan province of Iran. PARTICIPANTS People more than six years of age. INTERVENTION Intervention program consisted assembling Village Di...

Predictive modelling of turbulent combustion is important for the development of air-breathing engines, internal combustion engines, furnaces and for power generation. Significant advances in modelling non-reactive turbulent flows are now possible with the development of large eddy simulation (LES), in which the large energetic scales of the flow are resolved on the grid while modelling the eff...

BACKGROUND Floods represent a serious threat to human health beyond the immediate risk of drowning. There is few data on the potential link between floods and direct consequences on health such as on cardiovascular health. This study aimed to explore the impact of one of the worst floods in the history of Quebec, Canada on acute cardiovascular diseases (CVD). METHODS A cohort study with a tim...

Noroviruses are a leading cause of acute sporadic gastroenteritis worldwide. In Sub-Saharan Africa, information regarding norovirus infections in children is scarce. A systematic review of studies performed between 1993 and June 2015 was conducted to establish the genotypic distribution and prevalence of norovirus infections in children (≤17) in Sub-Saharan Africa. Analysis of data from 19 stud...
