We study crystalline surface evolution in extreme environments, where high-energy atoms impinge on a to cause sputtering, growth and roughening. For our model system, we the of Ni(111) under Ni atom bombardment, using Molecular Dynamics (MD) simulation Sutton-Chen force field, uppermost layers are free move, supported by thermostatically controlled above rigid template. The MD statistics sputte...

Introduction: Emergency medical services (EMS) personnel are subject to moral hazards during work, leading them to find moral distress (MD). Our literature review showed a gap in knowledge related to MD in EMS personnel. Therefore, this study investigated MD and its influential factors in pre-hospital emergency technicians. Methods: This descriptive-analytic study was conducted in Iran in 2017...

We study the size dependence of the dynamical symmetry breaking in the fourdimensional Nambu-Jona-Lasinio model. We show that the presence of boundaries reduces the chiral breaking region, and this effect is strengthened for a larger number of compactified dimensions. A critical value for the length of the compactified dimensions exists, below which the dynamical symmetry breaking is not possib...

The aim of this study was to characterize in vivo measurements of diffusion along the length of the entire healthy spinal cord and to compare DTI indices, including fractional anisotropy (FA) and mean diffusivity (MD), between cord regions. The objective is to determine whether or not there are significant differences in DTI indices along the cord that must be considered for future applications...

OBJECTIVE To determine the midpoint (MD) of extensor hallucis longus muscle (EHL) and compare the accuracy of different needle electromyography (EMG) insertion techniques through cadaver dissection. METHODS Thirty-eight limbs of 19 cadavers were dissected. The MD of EHL was marked at the middle of the musculotendinous junction and proximal origin of EHL. Three different needle insertion point...

the possibility of applying membrane distillation to support the fermentation process was investigated. the capillary polypropylene membranes were assembled in the membrane modules. the studies were carried out using the standard solutions containing the compounds frequently occurring in the broths such as ethanol, citric, acetic and lactic acids, glycerol and 1,3-propanediol. the performance o...

background: meniere’s disease (md) is a chronic illness defined as an idiopathic syndrome of endolymphatic hydrops. benign paroxysmal positional vertigo (bppv) is a balance disorder and can be the sequel of diverse inner ear impairments. objectives: the purpose of this study was to investigate the prevalence of bppv in md patients. materials and methods: all patients with definite or probable m...

To determine whether treatment with omega-3 fatty acids (ω-3 FA) provides benefits to patients with acute pancreatitis (AP). The Cochrane Library, PubMed, Embase, Web of Science, and Chinese Biomedical Literature Database were searched. Data analysis was performed using Revman 5.2 software. A total of eight randomized controlled trials (RCTs) were included. Overall, ω-3 FA treatment resulted in...

The lengths of G-tracts and their connecting loop sequences determine G-quadruplex folding and stability. Complete understanding of the sequence-structure relationships remains elusive. Here, single-loop G-quadruplexes were investigated using explicit solvent molecular dynamics (MD) simulations to characterize the effect of loop length, loop sequence, and G-tract length on the folding topologie...
