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 results of multiple IL-2 clinical trials (using a range of doses) have shown similar trends, in which IL-2 immunotherapy leads to an objective response in 15-20% of patients and complete response in 5-10%. Importantly, the majority (> 80%) of patients with a complete response maintain long-term responses. However, why only a small proportion of patients attain a complete response...

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...

“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...

Background and Objective: Human external exposure to natural radiation sources is much more than artificial radiation sources. In this study, external annual effective doses were estimated in cities of Gorgan and Bandar-Torkman by determining ambient gamma dose rate in indoor and outdoor spaces. Materials and Methods: Using an ionization chamber detector, the outdoor and indoor ambient gamma d...

Backgrounds and Objectives: Due to importance of ionizing radiation on human health, many studies have been performed to measure the background gamma radiation all around the world as well as some cities in lran. According to this fact that everybody spends almost 80% of his time in indoor areas, this study was carried out to measure the amount of background gamma radiation in indoor areas in Z...
