Stability of reinforced slopes is almost always carried out using limit equilibrium methods and controlled by the shear strengths of the slope materials and the extension force of reinforcements. According to limit equilibrium methods, the stability of slopes is assessed by dividing the whole failure wedge into several vertical elements. In order to determine the safety factor of the reinforce...

Reactive nitrogen (Nr) is removed by surface fluxes (air-surface exchange) and wet deposition. The chemistry and physics of the atmosphere result in a complicated system in which competing chemical sources and sinks exist and impact that removal. Therefore, uncertainties are best examined with complete regional chemical transport models that simulate these feedbacks. We analysed several uncerta...

ABSTRACT Systematic uncertainties in the mass measurement of galaxy clusters limit cosmological constraining power future surveys that will detect more than 105 clusters. Previously, we argued aperture masses can be inferred accurately and precisely 3D without loss power. Here, use Baryons Haloes Massive Systems (BAHAMAS) cosmological, hydrodynamical simulations to show are also less sensitive ...

There is limited information about inflammatory bowel disease in Arab children. Hence, the objective of this study was to report on the epidemiology of this condition in our community. Medical records were analysed for all children below 18 years of age diagnosed with inflammatory bowel disease (IBD) and followed up in our institution over a period of 10 years. From 1993 to 2002, 50 consecutive...

INTRODUCTION It is uncertain if plasma HIV-1 tropism is an independent predictor of short-term risk of clinical progression / death, in addition to the CD4 count and HIV RNA level. We conducted a nested case-control study within EuroSIDA to assess this question amongst people with current HIV RNA level >1000 copies/mL, including both people on ART and those ART naïve. METHODS People with an A...

INTRODUCTION As a consequence of poor productivity caused by a long anoestrous period, considerable research effort has been given to oestrus induction in dogs to enhance the productivity of young dogs and to preserve breeds. MATERIALS AND METHODS Oestrus was induced in 30 anoestrous bitches more than three months after the last oestrus. Bitches orally received fermented rice punch with or wi...

1. Poliomyelitis virus has been recovered in monkeys from 50 per cent of spinal cords, 10 per cent of olfactory bulbs, 50 per cent of tonsil-adenoid tissue, and from 26 per cent of the colon contents of autopsies; from the stools of 20 per cent of patients, and of 5 per cent of the contacts examined in this series. 2. Other materials as indicated in Table I were tested without success. 3. In au...

1. A group of 181 monkeys were infected intracerebrally with amounts of virus ranging from 0.01 to 0.05 cc. of a 10 per cent virus suspension. At different intervals following infection treatment of these animals was begun with daily injections of 5 to 100 mg. of natural vitamin C for a period of 2 weeks. Of 89 monkeys treated on the 1st or 2nd day of infection 26 (29.2 per cent) survived witho...

The relationship between the mechanical stability and the viability of N. gonorrhoeae (Type 4) in suspension was investigated. A correlation between viability and optical density recordings was often found. However, in spite of increased mechanical stability in solutions with low pH (5-2) or containing Cu++ or sucrose (10 per cent.), these environments were toxic to the gonococci. A viability p...
