This study examined household risk factors and prevalence, abundance, and distribution of immature Aedes aegypti and Aedes albopictus, and their association with socioeconomic and ecological factors at urban zonal and household levels in the city of Dhaka, Bangladesh. During the 2011 monsoon, 826 households in 12 randomly selected administrative wards were surveyed for vector mosquitoes. Result...

D iagnostic companies are facing ever-increasing pressures to deliver new products safely and efficiently. With diagnostic reagents as the basis of any experimental protocol, it is essential that they remain highly pure and that the potential for any contamination is minimized. Reagent packaging has commonly taken the form of glass bottles and containers, which have a well-known mode of failure...

Hybrid basalt fiber (BF) and Talc filled high density polyethylene (HDPE) and co-extruded wood-plastic composites (WPCs) with different BF/Talc/HDPE composition levels in the shell were prepared and their mechanical, morphological and thermal properties were characterized. Incorporating BFs into the HDPE-Talc composite substantially enhanced the thermal expansion property, flexural, tensile and...

The use of thoracic drains in connexion with water seals often causes difficulties, even in departments where these are used daily. The difficulties are (1) the cleaning of the bottles; (2) the fixing of the bottles to beds on which patients have to be moved; (3) that bottles break easily; and (4) that they take up too much space. In the University Hospital (Rigshospitalet) we have adopted a si...

The present study is designed to examine preschool children's (4-5 and 6 years old) attitudes toward unstructured materials and to take their divergent ideas about these materials. Paper napkin, a plastic bottle, bottle lid, toilet paper roll, a piece of white string, a plastic spoon and a 10x10x10 cm3 sized box were used as unstructured materials. 126 children (58 female, 68 male) were selecte...

Solar water disinfection (SODIS) is a simple, effective and inexpensive water treatment procedure suitable for application in developing countries. Microbially contaminated water is filled into transparent polyethylene terephthalate (PET) plastic bottles and exposed to full sunlight for at least 6h. Solar radiation and elevated temperature destroy pathogenic germs efficiently. Recently, concern...

A series of experiments is reported to identify and characterize the inactivation process in operation when drinking water, heavily contaminated with a Kenyan isolate of Escherichia coli, is stored in transparent plastic bottles that are then exposed to sunlight. The roles of optical and thermal inactivation mechanisms are studied in detail by simulating conditions of optical irradiance, water ...

Dead plant tissues and ash from a prescribed fire play an important role in nutrient balance and cycling in the Florida Everglades ecosystem. The objective of this study was to assess the dynamic changes in total phosphorus release (TPr) from ash or tissues of either cattail (Typha domingensis Pers.) or sawgrass (Cladium jamaicense Crantz) to water. Natural-dead (senesced-dead) and burning-dead...

BACKGROUND Commercial closed-suctions drainage systems are commonly used in the United States and many other countries for use in neurosurgical cases. However, in Tanzania and other developing nations with fewer resources, these are not available. This report explores another option for a closed-system drainage system utilizing inexpensive supplies found commonly in hospitals around the world. ...

The accurate indication of saliva collection time is important for defining the diurnal decline in salivary cortisol as well as characterizing the cortisol awakening response. We tested a convenient and novel collection device for collecting saliva on strips of filter paper in a specially constructed booklet for determination of both cortisol and DHEA. In the present study, 31 healthy adults (m...
