background although osteoporosis is a disease of adulthood, it can start from childhood and adolescence. lifestyle, especially physical activity, mobility, and proper nutrition during adolescence are among the important osteoporosis preventive factors. therefore, this study aimed to determine related factors of physical activity preventive behavior of osteoporosis based on the health belief mod...

conclusions given the importance of physical activity, and given that most women are at the pre-contemplation stage of the trans theoretical model, it seems necessary to devise educational interventional plans for the promotion of physical activities among women referred to health centers. patients and methods this was a cross-sectional study with 310 randomly selected females referred to healt...

backgroundbody image is a determinant of individual attractiveness and physical activity among the young people. this study was aimed to assess the association of trans-theoretical model based exercise behavior change with body image evaluation among the female iranian students.materials and methodsthis cross-sectional study was conducted in sanandaj city, iran in 2016. using multistage samplin...

aim: regular physical activity has several physical, psychological and social benefits. however, it is a global health problem, especially among icu nurses. therefore, in order to improve nurses’ physical activity, it is required to determine the effective correlated factors. the aim of this study was to delineate predictive factors on the physical activity of icu nurses based on a trans-theore...

abstract recharge of aquifers by using wastewater, is one of the important and applicable ways for reusing this valuable water resource, especially in arid and semi-arid regions. as the necessity of local practices for finding the proper management strategies and optimum use of recharge systems (conforming to climate, soil, etc.), a preliminary study was carried out. three physical models were ...

objective: educational models are used to study the behavior and plan for changing and determining the factors that affect the individuals’ decision making for conducting a behavior. this study aimed to compare the effects of the educational program based on basnef model and acupressure at gb21 point on the infants’ physical growth indicators.methods: this clinical trial was conducted on 150 (5...

molecular understanding of three-dimensional (3d) peptide: mhc models require both basic knowledge of computational modeling and skilled visual perception, which are not possessed by all students. the present model aims to simulate mhc molecular structure with the hands and make a profound impression on the students.

By the past two decades IPMCs have been intensively studied because of their special capabilities for actuation and sensing.This paper presents a theoretical physics based model for analyzing the behavior of IPMC sensors in fluid environments. The mechanical vibration of the IPMC strip is described by the classical Euler–Bernoulli beam theory. The model also takes in to account the physical pro...
