Bringt die Kombination einer Faszienzügelplastik mit der Kolposuspension nach Burch in der Therapie der weiblichen Stressinkontinenz Vorteile gegenüb…

PURPOSE Despite the development of new surgical techniques, the fascial sling procedure remains an important surgical technique for the treatment of female urinary stress incontinence. An advantage of combining it with an additional Burch colposuspension has been suggested. The objective of our study was to evaluate retrospectively selected patients who had undergone a fascial sling procedure with and without Burch colposuspension. MATERIALS AND METHODS Of a total of 390 females who underwent an incontinence operation at our department between 1990 and 1999, 56 patients had had a fascial sling plasty. A total of 50 patients (89 %) were followed for a median of 59.5 months. The median age wa…

Old-age protection for women in the Spanish pension system

2013

The example of Spain confirms the common view that contributory pension systems reproduce inequalities between the sexes that result from the nature of labour market structures and the sharing of family responsibilities. In general, women who stay at home are not entitled to their own pensions and are dependent on benefits of lower value such as survivors' pensions (derived entitlements) or non-contributory pensions. In turn, women who work outside the home accrue lower entitlements than men and, consequently, lower old-age or disability pensions (personal entitlements). The purpose of this article is to examine the figures for pension distribution by sex in Spain, review some of the pensio…

Trasporto di particelle sospese in una discontinuità di un prato di vegetazione acquatica

2010

La vegetazione acquatica influenza sensibilmente il campo di moto e il trasporto solido nei corpi idrici. Nelle aree sottocosta del Mar Mediterraneo sono molto diffusi i prati di Posidonia oceanica, una pianta costituita da un ciuffo di foglie nastriformi molto lunghe e flessibili. Spesso i prati sono interrotti da frequenti strisce di sabbia, e tali discontinuità, modificando sensibilmente il campo di moto, possono agire come “trappole” per i sedimenti. Nella presente memoria, sulla base di un campo di moto sperimentale, si simula numericamente il trasporto di particelle sospese in una tale discontinuità. A tal fine si adotta un semplice modello lagrangiano che assume assenza di velocità r…

A feedback control method based on an extended state observer (ESO) method is implemented to vibration reduction in a typical semiactive suspension (SAS) system using a magnetorheological (MR) damper as actuator. By considering the dynamic equations of the SAS system and the MR damper model, an active disturbance rejection control (ADRC) is designed based on the ESO. Numerical simulation and real-time experiments are carried out with similar vibration disturbances. Both the simulation and experimental results illustrate the effectiveness of the proposed controller in vibration suppression for a SAS system.

Synergistic and Antagonistic Effects of Combined Subzero Temperature and High Pressure on Inactivation of Escherichia coli

2006

ABSTRACT The combined effects of subzero temperature and high pressure on the inactivation of Escherichia coli K12TG1 were investigated. Cells of this bacterial strain were exposed to high pressure (50 to 450 MPa, 10-min holding time) at two temperatures (−20°C without freezing and 25°C) and three water activity levels (a w ) (0.850, 0.992, and ca. 1.000) achieved with the addition of glycerol. There was a synergistic interaction between subzero temperature and high pressure in their effects on microbial inactivation. Indeed, to achieve the same inactivation rate, the pressures required at −20°C (in the liquid state) were more than 100 MPa less than those required at 25°C, at pressures in t…

Solid–Liquid Suspensions in Top-Covered Unbaffled Vessels: Influence of Particle Size, Liquid Viscosity, Impeller Size, and Clearance

2014

Particle suspension in liquids is a unit operation commonly encountered in the process industry. Although it is usually carried out in baffled stirred tanks, there are some specific applications where the presence of baffles may be undesirable. In the present work solid-liquid suspensions are investigated in a radially stirred unbaffled tank provided with a top cover. The minimum impeller speed at which all solid particles get suspended (Njs) and the relevant power requirements (Pjs) are assessed. The dependence of these two parameters on physical properties (liquid viscosity, particle concentration, and size) and system geometrical configurations (impeller diameter and clearance) is invest…

Yield behavior of magnetorheological suspensions

2003

The rheology of suspensions containing magnetic particles of micrometer size is strongly modified by the application of a magnetic field. We first describe a model experiment where the suspension is made of spheres of millimeter size and we show that the experimental dependence of the yield stress is well predicted by a non-affine model where the chains of particles break in the middle. Then we compare these predictions with some experimental results obtained on suspensions of carbonyl iron; it is shown that this model does not apply in this case. We propose a mechanism where after some friction on the walls the aggregates begin to rotate and break at a strain smaller than unity, due to the…
