Background: Natural radionuclides in rock samples, primarily 238U (uranium), 232Th (thorium) and 40K (potassium), are the main source of radiation exposure to workers and general public and their measurement is of paramount importance from radiation protection point of view. Materials and Methods: Gamma spectrometry using HPGe detector was used to measure the radioactivity and assess the radiol...

386 students (181 female and 205 male) were selected randomly and asked to complete a demographic data sheet. rutter's internal and external locus of control and the beck depression inventory. data were analyzed by t-test and analysis of variance (anova). the results revealed, that 28% of students exhibited external locus of control, whereas, 72% exhibited internal locus of control. the me...

In the index to Appearance and Reality (First Edition) Mr. Bradley declares that all relations are “intrinsical”; and the following are some of the phrases by means of which he tries to explain what he means by this assertion. “A relation must at both ends affect, and pass into, the being of its terms” (p. 364). “Every relation essentially penetrates the being of its terms, and is, in this sens...

OBJECTIVE The objective of this study was to compare the torque and detorque values of screw intermediates of external hexagon, internal hexagon, and Morse taper implants in single restorations before and after mechanical cycling. MATERIALS AND METHODS The study sample was divided into three groups (n = 10) as follows: group EH - external hexagon implant, group IH - internal hexagon implant, ...

Background: Natural radiation is constantly present in the environment and is emitted from a variety of natural and artificial sources. It affects human body and environment. Materials and Methods: The activity concentrations of 238U, 232Th and 40K have been determined by Gamma ray spectrometer with an HPGe detector in sediments of Cauvery River, Tamilnadu, India. Results: The absorbe...

the study aimed to evaluate the correlation of maladjusted schema and locus of control with ocd, with the emphasis on cognitive approach to ocd.in this study, 273 iranian participants were selected; of whom, 30% were male and 70% were female. participants' age ranged from 19 to 34 and the mean age for the sample was 23.42(sd=2.46). participants completed questionnaire batteries including measur...

This article advocates using EEG coherence of specific brain areas as an internal indicator of mental effort [10] during learning processes in human brain. Preliminary results show that coherence between functionally coupled brain areas reflect partial processes in course of training – which are not reflected when we consider only reaction times. Analysis of coherence in β1and θ-frequency bands...
