background: health hazards associated with exposure due to the natural radioactivity which is a part of our physical environment are of great concern. in order to assess the risks associated with exposure due to the natural radioactivity in soil and building materials, extensive studies have been carried out all over the world. the most commonly encountered radionuclide’s are 238u, 232th, their...

An increase in radiation dose exposure In 2006, the average annual effective dose per individual in the US was 6.2 mSv1, a figure that has almost doubled over the last 25 years [1]. Approximately 50% of the dose currently received stems from background radiation [1], but varies depending on where you live (for example, in Australia dose levels are about half of levels in the US) [2]. The other ...

The in situ measured average outdoor absorbed dose rate in air was found to vary from 108.4 to 1596.4 nGy h at Homa Mountain area in southwestern Kenya. Rock and soil samples collected gave average values of the radioactivity concentrations of K, Ra and Th of 915.6, 195.3 and 409.5 Bq kg, respectively. The range of the annual effective dose for a person living in Homa Mountain area calculated v...

background: the use of high-dose steroid therapy peri portoenterostomy may have a positive impact on the frequency of cholangitis and survival rate.   methods: a prospective study was conducted on two groups of patients (less than three months of age) suffering from biliary atresia from 1999 to 2005. the patients in group i (g i) were managed peri-operatively by high-dose methylprednisolone whi...

We formulate a stochastic gauge fixing method to study the gauge dependence of Abelian projection. In this method, one can change the gauge from the maximally Abelian one to no gauge fixing continuously. We have found that the linear part of the heavy quark potential from Abelian contribution depends little on the gauge parameter. Similar results have been obtained for the monopole contribution...

aim : the aim of this study was to compare the half-dose and full-dose triple therapy regimens for helicobacter pylori ( hp ) eradication in patients with end-stage renal disease. background : h. pylori is one the most important causes of dyspepsia in patients with end-stage renal disease (esrd). patients and methods : sixty-six patients with esrd were enrolled in the study with hp infection an...

“The verifications of Hahnemann convince those who have intellectual integrity for scientific conviction, who will not sacrifice their intellectual integrity to the idols of the day, who will repeat Hahnemann’s experimental verifications of his scientific observations and inductions as they should be repeated. Any other method than to take into the healthy body four drams of China twice a day t...

The shocks and impacts encountered on small high-speed craft exceed the limits set for safe working practice according to current standards. European legislation regarding the exposure to vibration will have far reaching effects on the operators of such craft with respect to the safety of their employees. This paper sets out to highlight the vibration dose values that can be expected during typ...
