Hydrological response of a watershed is a comprehensive symbol of environmental conditions and characteristics of the basin. Vegetation is one of the main factors in water resources status, erosion, and sediment of a watershed. Rangelands of Golestan province, Iran due to the geographical location, climate, and destruction of these resources as well as drastic land use changes from forests, and...

instruction: measurement of brachial artery diameter variation by ultrasound methods has commonly been used to test the endothelial function. it is known that the artery diameter is increased by flow stimulation. therefore in the present study, the effect of external obstruction, as flow stimulation, on the radial strain of the brachial artery was assessed. also the biomechanical behavior of th...

STUDY DESIGN Cadaveric single vertebrae were used to evaluate vertebroplasty as a prophylactic treatment and as an intervention for vertebral compression fractures. OBJECTIVE To investigate the biomechanical characteristics of prophylactic reinforcement and postfracture augmentation of cadaveric vertebrae. SUMMARY OF BACKGROUND DATA Percutaneous vertebroplasty is a treatment option for oste...

In recent years, monitoring the compliance of business processes with relevant regulations, constraints, and rules during runtime has evolved as major concern in literature and practice. Monitoring not only refers to continuously observing possible compliance violations, but also includes the ability to provide fine-grained feedback and to predict possible compliance violations in the future. T...

After giving the periodontal tissues proper care, clinician must be able to estimate force systems and manage tooth movement in order close a gap. Frictional frictionless mechanics are used move orthodontic teeth during space closure. A detailed understanding of clinical scenario biomechanical concepts is necessary for choosing right mechanics.

OBJECTIVES To demonstrate the usefulness of computer simulation techniques in the investigation of pediatric stair falls. Since stair falls are a common falsely reported injury scenario in child abuse, our specific aim was to investigate the influence of stair characteristics on injury biomechanics of pediatric stair falls by using a computer simulation model. Our long-term goal is to use knowl...

background: plasterers are at risk of musculoskeletal disorders (msds) due to the nature of their occupation and ergonomic factors. the purpose of this study was to evaluate the biomechanical risk factors for msds among plasterers. materials and methods: in this descriptive study, 70 plasterers from neyshabur, iran, were studied in 2014. the nordic musculoskeletal questionnaire (nmq) was used t...

conclusions in contrast to the findings in humans and certain other species, glucocorticoid administration caused anabolic effect on the cortical bone of tibia diaphysis bone in rats. results glucocorticoid-treated rats showed weight loss and considerable mortality (21%). the biomechanical properties (maximum force) of glucocorticoid-treated rats in groups 4 (62 ± 2.9), 6 (63 ± 5.1), and 7 (60 ...
