Abstract The surface tension of the liquid Ti-V system is systematically measured using oscillating drop technique during electromagnetic levitation. Temperature- and compositional dependence are both investigated. entire range covered. A linear decrease with increasing temperature found for pure elements as well all investigated alloys. generally increases V-content. obtained data in good agre...

The maximal calcium-activated isometric tension produced by a skinned frog single muscle fiber falls off as the ionic strength of the solution bathing this fiber is elevated declining to zero near 0.5 M as the ionic strength is varied using KCl. When other neutral salts are used, the tension always declines at high ionic strength, but there is some difference between the various neutral salts u...

Tension is a complex multidimensional concept that is not easily quantified. This research proposes three methods for quantifying aspects of tonal tension based on the spiral array, a model for tonality. The cloud diameter measures the dispersion of clusters of notes in tonal space; the cloud momentum measures the movement of pitch sets in the spiral array; finally, tensile strain measures the ...

OBJECTIVES To investigate the effect of rigid taping that induces mechanical displacement of the skin on pain perception. DESIGN Single group experiment design with repeated measures. METHODS Twenty-three active healthy volunteers (12 men and 11 women) participated in the study. All participants received three different taping procedures: no tape, taping with tension, and taping without ten...

INTRODUCTION Pathological features of disease appear to be quite different. Despite this diversity, the common feature of various disorders underlies physicochemical and biochemical factors such as surface tension. Human biological fluids comprise various proteins and phospholipids which are capable of adsorption at fluid interfaces and play a vital role in the physiological function of human o...

background: research into the role of neuroimaging in primary headaches such as tension type headache (tth) is ongoing. in the present study, we aim to evaluate the ability of neuroimaging to detect potential abnormalities in patients with new onset tth and normal neurological exam. materials and methods: in a prospective study, 294 cases of new onset tth with normal neurological exam, that had...

objective: this study compared the tension-free vaginal tape (tvt) and transobturator tape (tot) procedures for surgical treatment of stress urinary incontinence in women. materials and methods: this prospective non randomized clinical trial was conducted in vali-e-asr hospital from march 2001 to march 2005. a total of 71 patients with clinical and urodynamic diagnosis of stress urinary inconti...
