The effects on human health of exposures to ionizing radiation at low doses have long been the subject of dispute. In this paper we focus on open questions regarding the health effects of low-dose exposures that require further investigations. Seemingly contradictory findings of radiation health effects have been reported for the same exposed populations, or inconsistent estimates of radiation ...

background: high level radiation areas have been recognized on various parts of the earth. mahallat hot spring region is one of these areas. study of exposure in these areas can be helpful in investigating the effects of ionizing radiation. internal and external exposure to the staff was studied. materials and methods: used materials and instruments include: rss-112 ionizing chamber for environ...

abstract introduction:  this study was performed to compare the effects of low-dose interferon beta-1(cinnovex,30 mcg) and high-dose interferon beta-1(rebif,44 mcg) on the reduction of the number and size of plaques in magnetic resonance imaging (mri) in patients with multiple sclerosis (ms). methods and materials: this historical cohort study, which was performed in 2014 in sanandaj (western p...

In elicitation tasks, people are asked to make estimates under conditions of uncertainty but elicitors then interpret these estimates as if the estimator were certain of them. An analysis of people’s patterns of responding during the elicitation of uncertainty, indicates that there are markers of confidence incorporated into these estimates that can be used to predict the person’s true level of...

The process of convening arbitrary real numbers bito a floating poini format is formalized as a mapping of the reals into a specified subset of real numbers. The structure of this subset, the set of n significant digit base ß floating point numbers, is analyzed and properties of conversion mapp.ngs are determined. For a restricted conversion mapping of the n significant digit base ^numbers to t...

In this paper, we analyze the distribution of the eigenvalues of glued tridiagonal matrices. Such matrices provide a useful class of test matrix because, despite being unreduced, a glued matrix can have some eigenvalues agreeing to hundreds of decimal places. A glued matrix can be obtained from a direct sum of p copies of an unreduced symmetric tridiagonal matrix T by modifying the junctions, i...

2 The memory entitled " Theoretical study of the fluorinating power of SF 6 to vanadocene " corresponds to the work carried out by Luis Martínez Suárez to obtain the Official Master Title on Computational and Theoretical Chemistry, done in the Departament de Química Física of the Universitat de Barcelona and supervised by Dr. Juan J. Novoa Vide, whom certifies and gives his consent to its prese...
