Background: Neural tube defects are common and major birth defects. Their incidence varies according to the geographic conditions, race, sex of the baby and certain maternal conditions. This study was conducted to determine the incidence of neural tube defects and its risk factors in Peshawar. Material and Methods: It was retrospective study of deliveries at Gynae A unit of Lady Reading Hospita...

Laser Interferometer Gravitational-Wave Observatory ~LIGO! is a joint project of the California Institute of Technology and the Massachusetts Institute of Technology funded by the National Science Foundation. The project is designed to detect gravitational waves from astrophysical sources such as supernova and black holes. The LIGO project constructed observatories at two sites in the U.S. Each...

Eddy current technique has played an important role in the understanding of the corrosion behavior of steam generator components. Until recently, its role has been primarily in the evaluation of the condition of the heat exchanger tubes. Recent developments have led to the use of this technique for detecting corrosion of the carbon steel plates supporting the tubes. The detection and quantifica...

The commercialization of lithium-sulfur batteries is hindered by low cycle stability and low efficiency, which are induced by sulfur active material loss and polysulfide shuttle reaction through dissolution into electrolyte. In this study, sulfur-impregnated disordered carbon nanotubes are synthesized as cathode material for the lithium-sulfur battery. The obtained sulfur-carbon tube cathodes d...

An effective approach to sustainable energy is the utilization of solar energy. The parabolic trough collector with central receiver is one of the most suitable systems for solar power generation. A type of concentrating solar collector that uses U-shaped troughs to concentrate sunlight onto a receiver tube, containing a working fluid such as water or oil, which is positioned along the focal li...

During the course of biochemical and genetic studies with Panagrellus redivivus, we required large numbers of sexually immature nematodes. Initially we used filtration through glass beads, a method devised to obtain size-synchronized cultures (1, 2, 3). However, these methods were found to be inefficient because large losses of nematodes were encountered. We now use a simple, rapid, and inexpen...
