A simple, accurate screening test for significant bacteriuria is described. It entails brief contact of a freshly voided specimen of urine with the surface of a solid culture medium lining the wall of a transparent disposable plastic container, incubating it at 37 degrees C for 24 hours, and counting colonies developing on a proscribed surface area. The method obviates errors due to contaminant...

Ecological studies of larval mosquitoes usuallv require collecting numerous samples. Mani, samples containing mosquito larvae contain substantial quantities of debris which must be separated from the larvae. This can be a tedious and time consuming task. Water claritv mav also make separation of larvae and pupae from the sample difficult. We developed a simple and inexpensive apparatus that can...

In this paper we review recent progress in materials, fabrication processes, device designs, and applications related to organic thin-film transistors (OTFTs), with an emphasis on papers published during the last three years. Some earlier papers that played an important role in shaping the OTFT field are included, and a number of previously published review papers that cover that early period m...

BACKGROUND A large proportion of the plastic surgery literature is dedicated to the breast. It is one of the most common topics in our specialty, yet it is unclear which articles have been the most influential. The purpose of this study was to identify the top 100 most-cited articles on breast in the plastic surgery literature and examine the characteristics of each individual article. METHOD...

Powdered refined- and semi-refined carrageenans (RC SRC) have been characterized as alternative raw materials for industrial bioplastic production. Several basic parameters, i.e., the melting temperature, crystallinity, chemical structure (FTIR), tensile properties, were observed. The temperature of RC was slightly higher than that SRC, 176 °C 172 °C, respectively. These temperatures correspond...

In this work, we have successfully fabricated bottom gate fully transparent tin-doped zinc oxide thin film transistors (TZO TFTs) fabricated on flexible plastic substrate at low temperature by RF magnetron sputtering. The effect of O2/Ar gas flow ratio during channel deposition on the electrical properties of TZO TFTs was investigated, and we found that the O2/Ar gas flow ratio have a great inf...

A modified capillary-growth method is described that has substantial advantages for standard and high-throughput protein crystal growth. Protein-containing drops are injected into vapor-permeable flexible X-ray-transparent polyester tubing. The protein concentration in the drop increases over time by water transport through the tubing wall at a rate controlled by the wall thickness and ambient ...
