This paper deals with the development of a model for concrete subjected to dynamic loads. Shock waves are generated by Pulsed Arc Electro-hydraulic Discharges (PAED) in water and applied to mortar samples. A diphasic model (liquid water and vapour) is implemented in order to describe the electrical discharge and the propagation of shock waves in water. An anisotropic damage model is devised, wh...

The dilution biochemical oxygen demand (BOD) test has widespread application for design and operation of wastewater treatment processes, evaluating the quality of natural waters, and assessing the effect of wastewater discharges on these waters. While standardization of the BOD-measuring method has become of prime importance in maintaining dependable data acquisition, changes are made as needed...

To determine whether neuronal oscillations are essential for long-range cortical synchronization in the somatosensory system, we characterized the incidence and response properties of gamma range oscillations (20-80 Hz) among pairs of synchronized neurons in primary (SI) and secondary (SII) somatosensory cortex. Synchronized SI and SII discharges, which occurred within a 3 msec period, were det...

OBJECTIVE The combination of a single pedicle local flap with tattooing for complete nipple areola complex (NAC) reconstruction is currently the most supported method. Although many technical descriptions of NAC reconstruction exist in the medical literature, there are no data that define the ideal areola size (diameter of the areola) after bilateral mastectomy and breast reconstruction conside...

The ability to obtain breast fluid by nipple aspiration was examined in relation to self-reported dietary fat intake in 1347 white and 153 black women. Study participants were between 20 and 59 years of age, were not pregnant or breastfeeding, and had no history of breast cancer. The proportion of women from whom nipple aspirate fluid was obtained increased with increasing dietary fat consumpti...

Combined sewer overflow (CSO) structures are constructed to effectively discharge excess water during heavy rainfall, to protect the urban drainage system from hydraulic overload. Consequently, most CSO structures are not constructed according to basic hydraulic principles for ideal measurement weirs. It can, therefore, be a challenge to quantify the discharges from CSOs. Quantification of CSO ...

Rabbits (Oryctolagus cuniculus) are often presented suffering from urolithiasis. A high water intake is important in the prophylaxis of uroliths. We investigated the influence factors for water intake using 12 rabbits subjected to different feed and water regimes with practical relevance: Hay, fresh parsley, a seed mix and two different pelleted feed were offered in diverse combinations. Water ...

In recent years there has been considerable concern over the ability of substances discharged into the environment to disrupt the normal endocrine function of wildlife. In particular, the apparent widespread feminization of male fish in rivers has received significant attention from regulators in the United Kingdom, the United States, Europe, and Japan. The U.K. and European epidemiological dat...

A 36-year-old woman came to our OPD with presentation of a solitary, indurated, nonpainful subcutaneous plaque on the left nipple area for 2 months. There was neither discharge nor ulceration. Axillary's lymph node was not palpable. Histopathological examination directed the diagnosis to microcystic adnexal carcinoma. A wide excision was performed with negative margin. The preoperative and intr...
