o bjectives: the aim of this study was to investigate the displacement and stress distri- bution during surgically assisted rapid maxillary expansion under different surgical conditions with tooth- and bone-borne devices. materials and methods: three-dimensional (3d) finite element model of a maxilla was constructed and an expansion force of 100 n was applied to the left and right molars and pr...

background: in recent years significant medical science advances have been made in the field midwifery and infant care. the premature, low birth weight and ill infants are admitted to the technologically advanced nicu for care and they often require long‑term stay. this study addresses parental experiences with the infant care in nicu, explores their concerns regarding nursing supports for pare...

abstract in order to study the effects of quantitative and qualitative traits on cooking characteristics and protein percentage of 15 red bean genotypes, a randomized complete block design was conducted with three replications in normal irrigation and drought stress. these traits were measured in farm and nutrition laboratory employing international standard of ciat. analyses of variance showed...

background & aim : stress is a common phenomenon in nursing profession, but novice nurses usually experience more stress. this stress can result in job dissatisfaction and quitting the occupation. this study aimed to explore the novice nurses’ experience of stress at the beginning of their clinical practice. methods & materials : this study was conducted using a qualitative content analysis. th...

in this article, thermo-elastic-behavior of a thick-walled cylinder made from a polystyrene nanocomposite reinforced with functionally graded (fg) single-walled carbon nanotubes (swcnts) was carried out in radial direction while subjected to a steady state thermal field. the swcnts were assumed aligned, straight with infinite length and a uniform layout. two types of variations in the volume fr...

following the recent work of the authors in development and numerical verification of a new kinematic approach of the limit analysis for surface footings on non-associative materials, a practical procedure is proposed to utilize the theory. it is known that both the peak friction angle and dilation angle depend on the sand density as well as the stress level, which was not the concern of the fo...

conclusions the current study showed that supporting pregnant mother moderates psychological problems such as stress, anxiety, and depression, and hence reduces preterm labor. results the final path model fit well (cfi = 0.96; rmsea = .064). the results showed that depression, anxiety, and stress (β = -0.18) directly, and stressful life events indirectly (β= -0.0396) had the most predict on ges...

in this paper, first design and analysis history of full metal cng cylinders for vehicle are investigated. next with respect to the cng worldwide standards, a full metal type cylinder is designed and analysed. then the numerical analysis results and practical results are compared, and the correctness of the investigation is verified. in the end, the most suitable alloy with respect to the dimen...
