Surfactant spreading on thin viscous films is of interest in the context of surfactant and liquid transport in the lungs, for both normal lung function and treatment of disease, as well as for many industrial processes. This paper presents experimental techniques for the measurement of film deformations due to spreading surfactant and for the investigation of the effects of periodic stretching ...

The aim of this study was to present our experience of patients with penile strangulation. The clinical data of 6 patients (mean age, 36 years; range, 18-72 years) with penile strangulation caused by a metal hoop are provided, where the duration of strangulation was between 3 h and 1 month. Among these patients, the case of a 22-year-old patient with a steel hoop entrapment on his penis for 5 d...

PURPOSE The aim of this review was to investigate the effect of initial graft tension on patient-specific functional outcomes after anterior cruciate ligament reconstruction and determine whether a particular tension is associated with superior functional outcome. METHODS We performed a systematic review of prospective randomized trials with a National Health and Medical Research Council Aust...

A tension pneumothorax is one of the main causes of cardiac arrest in the initial postoperative period after thoracic surgery. Tension pneumothorax and cardiac herniation must be taken into account in hemodynamically unstable patients after pneumonectomy. We report an unusual case of successful treatment of acute tension pneumothorax following cardiac herniation and intrathoracic bleeding after...

Concerns exist regarding the tension developed in a reconstructed anterior cruciate ligament (ACL) during open chain knee extension exercises used to rehabilitate the knee. Therefore, the primary objective was to measure tension in an ACL graft during a simulated open chain knee extension exercise as a function of ankle weight. A secondary objective was to determine whether the graft tension wa...

Normal 0 false false false EN-US X-NONE AR-SA The ratio of compression yield strength to the initial tensile yield strength is called Bauschinger effect factor, BEF. A nonlinear strain hardening mathematical model is proposed for 7075 aluminium alloy (A7075). Uniaxial tension-compression experimental data are used to figure out a suitable model to study the BEF. Hence, uniaxial tension-co...

Tension of the frog heart irradiated by nonuniform electromagnetic field was investigated. Tension changes up to 50% of initial values were observed. The presence of a.c. field gradient is viewed as a possible reason for such alterations.

Abstract The violent disruption of the coronal magnetic field is often observed to be restricted low corona, appearing as a confined eruption. possible causes confinement remain elusive. Here, we model eruption flux rope in quadrupolar active region, with parameters set such that X-lines exist both below and above rope. This facilitates onset reconnection either place but partly opposing effect...
