Introduction: Academic buoyancy is one of the effective variables in the field of education and learning environment of students. Therefore, the aim of this study was to design a model of academic buoyancy based on life expectancy mediated by happiness in female high school students in Hamadan. Method: The research method was correlational and structural equations. The statistical population in...
Phytoplankton cells have evolved sophisticated strategies for actively responding to environmental signals, most notably to mechanical stresses of hydrodynamic origin. A largely unanswered question, however, is the significance of these cellular responses for the largely heterogeneous spatial distribution of cells found in the oceans. Motivated by the physiological regulation of buoyancy preval...
This study aims to investigate the relationship between wisdom and psychological well-being and academic buoyancy of students. This is a correlation study. The statistical population of this research includes all high school Secondary students of Khusf town, and 317 students were selected through cluster random sampling method. Research tools employed include Wisdom Scale of Ardelt, psychologic...
this paper is concerned with asphaltene deposition in fluid flowing through pipelines. brownian diffusion and drag, gravitational, thermophoresis, buoyancy, and shear removal are considered as possible mechanisms in the asphaltene deposition process. the thermo-physical properties of the fluid were obtained from iranian oil fields. a model was used in the pipeline deposition modeling to predict...
Aim: The aim of this study was to develop a model of academic buoyancy based on school connection, family emotional atmosphere, motivation, self-efficacy, and academic engagement of students. Methods: This research was of descriptive-correlational. The statistical population of the study included all first and second grade high school students in Isfahan in 2018-2019. From among them, a sample ...
Background and Objective: One of the major education quality indicators is students’ academic engagement, which could be influenced by students' academic buoyancy and effective teacher features. The present study aimed to investigate the relationship between effective teacher features and academic engagement mediated by academic buoyancy of post-graduate students at Sistan and Baluchestan Unive...
Introduction: The purpose of present study was to investigate the mediating roles of academic buoyancy and humor in the relationship between academic emotions and academic engagement. Methods: The sample consisted of 332 post- graduate students. The research instruments included academic engagement questionnaire (Rio, 2013), achievement emotions questionnaire (Pekrun & et.al, 2002), epistemic c...
Background and Aims: Medical students due to the difficulty of the lessons and future job sensitivity need to academic buoyancy and sometimes experiencing academic burnout. As a result, the aim of this research was determine the effectiveness of schema therapy on academic buoyancy and academic burnout of medical students. Methods: This research was a semi-experimental with a pre-test and post-t...
Buoyancy of Phaeocystis globosa Scherffel (Prymnesiophyceae) colonies was investigated by measuring the vertical distribution of colonies in quiescent water where convection had been removed. Over 60% of the colonies exhibited negative buoyancy regardless of light condition or growth phase. Positively and neutrally buoyant colonies lost their buoyancy in the dark, but regained buoyancy upon ret...
