social interest is human phenomenon which can be considered as structure of personality in psychology. this descriptive correlation study aimed to investigate self efficacy, social acceptance and locus of control as predictors of social interest. this was correlational study. the sample consisted of 153 boys and 147 girls who were studying at private middle schools. multistage cluster sampling ...

introduction: nowadays, eating fast food among youth is one of the health issues in iran as well as other countries around the world, and nearly one-third of these people eat such food. this study was meant to evaluate attitudes, normative and control beliefs as well as self-efficacy of students regarding consumption of fast food among students of hamadan university of medical sciences. methods...

background and aim: nosocomial infections have been always among the major problems of healthcare delivery systems. the operating room is an appropriate place for causing severe nosocomial infections. knowledge of infection control guidelines and standards is the key to infection prevention. this study was conducted to investigate nurses’ knowledge and self-efficacy regarding the principles of ...

Religiosity is related to a variety of positive outcomes and the nature of this relationship has long been a topic of inquiry. Recently, it was proposed that an important piece of this puzzle may be the propensity for religious beliefs to promote self-control, a trait that is linked to a range of benefits. How religion translates into self-control, however, remains unclear. We examined the exte...

Surface functionalization with DNA is a powerful tool for guiding the self-assembly of nanometre- and micrometre-sized particles. Complementary 'sticky ends' form specific inter-particle links and reproducibly bind at low temperature and unbind at high temperature. Surprisingly, the ability of single-stranded DNA to form folded secondary structures has not been explored for controlling (nano) c...

By using the particle swarm optimization (PSO) algorithm, a novel design method for the self-tuning PID control in a slider–crank mechanism system is presented in this paper. This paper demonstrates, in detail, how to employ the PSO so as to search efficiently for the optimal PID controller parameters within a mechanism system. The proposed approach has superior features, including: easy implem...

In this paper, a combination of relay feedback identification and an algebraic control design method for stable systems is studied. Models with up to three parameters are estimated by means of a single asymmetrical relay experiment. Then a stable low order transfer function is identified. Then the controller is analytically derived from general solutions of Diophantine equations in the ring of ...
