The objective of the present study was to investigate the strength of the three heads of triceps brachii muscle during handgrip force exercise with full elbow extension through surface electromyography. The myoelectric signals were recorded from the lateral, long and medial heads of triceps brachii muscle of 11 healthy men during maximal isometric contractions for 10-s of concurrent handgrip fo...

We examined the vection induced by consistent and conflicting multisensory information about self-motion. Observers viewed displays simulating constant-velocity self-motion in depth while physically oscillating their heads left-right or back-forth in time with a metronome. Their tracked head movements were either ignored or incorporated directly into the self-motion display (as an added simulat...

BACKGROUND AND OBJECTIVES There is a lack of evidence on the value of head circumference (HC) as a screening measure. We aimed to describe the incidence of head centile shifting and the relationship between extremes of head size and later neurodevelopmental problems in the Avon Longitudinal Study of Parents and Children. METHODS HC was measured routinely at 2, 9, and 18 or 24 months and by re...

Increased oxidative stress is considered one of the main causes of steroid-induced osteonecrosis of the femoral head (ONFH). The aim of this study was to evaluate the effects of a steroid hormone and pentosan polysulfate sodium (pentosan), a heparin analog, in stroke-prone spontaneously hypertensive rats (SHRSP) as a model of ONFH. One hundred twenty-three 13-week-old male SHRSP/Izm rats were d...

The study presented here attempts to quantify the significance of southerly water vapor fluxes on precipitation occurring in the eastern Fertile Crescent region. The water vapor fluxes were investigated at high temporal and spatial resolution by using a Regional Climate Model [fifth-generation Pennsylvania State University–NCAR Mesoscale Model (MM5)–Noah land surface model] to downscale the NCE...

The effect of basalt fibers, produced by the Junkers technology and used as reinforcement in polymer composites, was modeled on the properties of composites, adapting the statistical fiber mat model of Poisson type. The random distribution was approximated by so-called effective spheres that act as defect sites in composites, reducing their strength. The role of fiber heads in strength reductio...

Bacteriophage T4 capsids seem to be assembled on E. coli protoplasmic membranes. This process seems to involve "lumps" of head protein, which convert to tau particles, which in turn give rise to empty heads. The empty heads leave the bacterial membrane and are then filled with DNA in the central region of the cell. T4 gene 16 and 17 products appear to be necessary for head filling.

Mapping of groundwater level observations often makes very little use of auxiliary data and is often undertaken simply by manual interpolation or ordinary kriging of the heads. Recently, a number of geostatistical methods have emerged that significantly improve estimates by incorporating the land surface elevation and groundwater flow or drawdown equations. However, at the regional scale heads ...

Introduction Pronator teres usually originates as two heads, the superficial humeral head from medial epicondyle and the deep ulnar head from the coronoid process. The median nerve passes between the two heads, and the ulnar artery passes deep to the deep head of the pronator teres in the cubital fossa. Flexor carpi radialis, another superficial flexor of the forearm arises from common flexor o...
