We create air bubbles at the tip of a "bathtub vortex" which reaches to a finite depth. The bathtub vortex is formed by letting water drain through a small hole at the bottom of a rotating cylindrical container. The tip of the needlelike surface dip is unstable at high rotation rates and releases bubbles which are carried down by the flow. Using high-speed imaging we find that the minimal neck ...

PURPOSE Surgical transfers of muscles are used to restore lateral pinch in tetraplegia; however, outcomes are variable. The purpose of this study was to compare activation of the brachioradialis (Br) after transfer to the flexor pollicis longus during maximum effort in its primary function (elbow flexion) with maximum effort in its postoperative function (lateral pinch) and to record Br activat...

Particularly interesting new cysteine-histidine-rich protein (PINCH) protein is part of the ternary complex known as the IPP (integrin linked kinase (ILK)-PINCH-Parvin-α) complex. PINCH itself binds to ILK and to another protein known as Rsu-1 (Ras suppressor 1). We generated PINCH 1 and PINCH 2 Double knockout mice (referred as PINCH DKO mice). PINCH2 elimination was systemic whereas PINCH1 el...

Introduction: Grip and pinch strength assess the function of hand and is considered as a sign of general health. Considering the high prevalence of related-work musculoskeletal disorders (WMSDs) due to the incongruity of work with the workers and preventability of diseases that are caused by such incongruity, we decided to study the relationship between maximum oxygen consumption (Vo2max) and w...

OBJECTIVE Particularly interesting new cysteine-histidine rich protein (PINCH) is an important component of the local adhesion complexes and upregulated in several types of malignancies, and involved in the incidence and development of tumours. PINCH expression is also independently correlated with poorer survival in patients with colorectal cancer. However, there is no study of PINCH in gastri...

It is proposed to use the pinch technique to obtain the gauge-independent thermal β function βT in a hot Yang-Mills gas. Calculations of βT are performed at one-loop level in four different gauges, (i) the background field method with an arbitrary gauge parameter, (ii) the Feynman gauge, (iii) the Coulomb gauge, and (iv) the temporal axial gauge. When the pinch contributions to the gluon self-e...
