BACKGROUND This study tested a mediated effects model of psychological and behavioral adaptation to puberty within the context of physical activity (PA). METHODS Biological maturity status, physical self-concept, PA, and health-related quality of life (HRQoL) were assessed in 222 female British year 7 to 9 pupils (mean age = 12.7 years, SD = .8). RESULTS Structural equation modeling using m...

Thermal modeling of an automotive cabin was performed in this paper to predict the inside cabin air temperature. To implement this task, thermal and ventilation loads were estimated and the mass and energy balance conservation equations for dry air and water vapor with considering a new parameter (air circulation ratio) as well as the balance equations of internal components of a cabin were de...

In the current study, a thermal model was used to investigate the effects of welding parameters on the distribution of temperature in wide gap aluminothermic rail welds. To solve the governing thermal equation, SUTCAST, a finite difference program (FDM) was employed while different aspects such as phase change and convective heat transfer in weld pool were taken into account in the numerical so...

[1] The southern flanks of the central Nepalese Himalaya correspond to a sharp transition in landscape morphology and bedrock mineral cooling ages that suggests a change in rock uplift rate. This transition can be explained by either (1) accretion of footwall material to the hanging wall across a ramp in the décollement separating India from Eurasia, thereby enhancing rock uplift rates above th...

in order to investigate effect of deficit irrigation on phenological stages and yield of soybean cultivars, an experiment was conducted as split plots based on randomized complete block design with three replications at agricultural research farm, university of guilan in 2009. main factor was included four irrigation levels based on potential moisture 30-35 (i1), 50-55 (i2), 70-75 (i3) centibar...

This paper presents an approach of compact thermal modeling — HotSpot, which is parameterized according to design geometrical dimensions and material physical properties. While most existing compact thermal modeling methods facilitate thermal analysis of existing package designs, the HotSpot modeling method is more suitable for the exploration of new designs at both the die level and the packag...

SYNOPSIS. The majority of ectotherms grow slower but mature at a larger body size in colder environments. This phenomenon has puzzled biologists because classic theories of life-history evolution predict smaller sizes at maturity in environments that retard growth. During the last decade, intensive theoretical and empirical research has generated some plausible explanations based on nonadaptive...

Background: The importance of promoting job motivation in the workplace has led to the study of factors affecting it. Employeeschr('39') psychological maturity has received less attention as an important factor. On the other hand, work ethics or value tendency to work is a very important factor that is examined in this study as a mediator. Therefore, the purpose of this study is to investigate ...
