UNLABELLED An integrated elastomeric microfluidic device, with a footprint the size of a postage stamp, has been designed and optimized for multistep radiosynthesis of PET tracers. METHODS The unique architecture of the device is centered around a 5-microL coin-shaped reactor, which yields reaction efficiency and speed from a combination of high reagent concentration, pressurized reactions, a...

R ECENT ADVANCES in aircraft design have made possible attainment of altitudes in which man is unable to live, even while breathing pure oxygen. This difficulty has been overcome by the development of pressurized cabins and, to some extent, by the use of pressure-breathing equipment. The latter effectively increases alveolar oxygen tension; however, there has been some uncertainty as to whether...

Aeromedical transport is challenging not only because of limitations of equipment, unfamiliar surroundings, and challenging environmental conditions, but also due to difficulty in developing methodologies for research and data collection. To our knowledge, neurological changes at the oxygen tensions of a pressurized cabin have not been systematically studied. Here we report a case of intracrani...

Multicycle reuse of disperse dyebaths on pilot scale jet equipment was investigated in dyeing of staple and filament 100% polyester knit fabrics. Long reuse runs of single shades produced good batch-to-batch shade uniformity. Multishade reuse runs were found feasible in the forward (light-mediumdark) direction for both fabric types even though dyes were not completely common in successive shade...

An environmental friendly palm-grease has already been formulated from modified RBDPO (Refined Bleach Deodorized Palm Oil) as base oil and lithium soap as thickener. Such palm-grease is dedicated for general application and or equipment working in areas where biodegradability is required such as in agriculture, forestry and coastal marine, recreation areas. The grease was manufactured via 4 ste...

Compressed Air Energy Storage (CAES) is a process for storing and delivering energy as electricity. A CAES facility consists of an electric generation system and an energy storage system. Only earth based geological structures can currently store adequate potential energy in the form of a pressurized air mass required by commercial electric turbines. Earth based structures suitable for service ...

In the recent years, we have witnessed a growing consumption of carbonated beverages like soft drinks and beer, marketed in attractive containers and packaging. Technology has certainly played its part in the increased consumption of carbonated beverages with the adventof glass bottles, cans, plastic bottles, high speed packaging lines and evolving packaging systems. Packaging carbonated produc...

pressurized irrigation technologies of course have the potential to raise the productivity of land and water; but, these technologies could not popularize among the smallholders who own millions of farms worldwide. in developing pressurized irrigation technologies, particularly for field crops irrigation, researchers and manufacturers have developed more specialized and expensive technologies w...
