background: proper sleep is essential for the development of premature infants. infants, during hospitalization, might suffer from inappropriate postures and insufficient sleep hours. to compare the daily sleep quantities of premature infants in flexed (facilitated fetal tucking) posture and extended (free body) posture. this study is a randomized clinical trial which was conducted in neonatal ...

conclusion safety-related parameters of posterolateral and posterior approaches in supine thoracentesis are far better than that of the conventional lateral approach. background in patients who have difficulty sitting, thoracentesis is attempted in a supine position via lateral approach. recently, a new table has been designed for supine thoracentesis. this table has gaps that allow access to t...

In this paper, the laser bending process of a circular tube made of mild steel has been investigated experimentally. For this purpose, the effects of the irradiating length and the number of irradiating passes on the main bending angle of a laser bent tube are studied. In addition, the main defects of the laser tube bending process such as lateral bending angle, ovality and thickness variation ...

Objective(s) The objective of this study was to document and explain bilateral differences in the Q angle. Materials and Methods Two hundred limbs of healthy adult Indian volunteers were studied. The Q angle was measured using a goniometric method with the subjects supine, quadriceps relaxed and lower limbs in neutral rotation. The relative lateral placement of the tibial tuberosity with res...

Analyzing piles subjected to lateral loads significantly depends on soil resistance at any point along the pile as a function of pile deflection, known as p-y curve. On the other hand, the deformation characteristics of soil defined as “the soil strain at 50% of maximum deviatoric stress (ε50)” has considerable effect on the generated p-y curve. In this research, several models are proposed to ...

to evaluate differences in the root and canal configurations of mandibular permanent anterior incisors and canines in an iranian population by means of cone beam ct (cbct) images.four hundred cbct images of mandibular permanent incisors and canines that met the inclusion criteria were evaluated. vertucci's classification was used to evaluate the number of roots, number of root canals, root leng...

amyotrophic lateral sclerosis (als), the most common form of motor neuron disease, is a progressive and devastating disease involving both lower and upper motor neurons, typically following a relentless progression towards death. therefore, all efforts must be made by the clinician to exclude alternative and more treatable entities. als with laboratory abnormalities of uncertain significance is...
