Finite element method (FEM) based analysis using the SEEP/W and SLOPE/W sub-programme options of a GEOSTUDIO software was used to analyze Saura-Keffi earth dam in Nasarawa State, Nigeria with view seepage its stability. The created geometry assigned material properties boundary conditions at reservoir water levels of: minimum (3 m), normal (6 m) maximum (7 m). conducted under cases that without...

The hemodynamic mechanism of blood pressure response to angiotensin blockade is well established in "benign" but not in human malignant hypertension. We studied the changes in mean arterial pressure (MAP), cardiac index (CI), pulmonary wedge pressure (PWP), and in plasma volume (PV) induced by a single oral dose of captopril (150 mg) in 11 patients with malignant hypertension. Two hours after c...

It has long been established that pore water pressure (pwp) variations affect the stability and serviceability of slopes. Pwp may be due to consolidation/swelling processes within soils low permeability or seasonal evapotranspiration precipitation processes. The simultaneous study such phenomena hydro-mechanical coupling in sloping ground requires use advancednumerical methods. Often, infrastru...

Objectives. To explore the experiences of people with Parkinson's (PwP) who suffer from constipation, the impact this has on their lives, and the effect of using lifestyle changes and abdominal massage as a form of constipation management. Method. Fourteen semistructured interviews were completed (8 males and 6 females; mean age 72.2 years) at the end of a care programme, which consisted of eit...

Semi-arid North-central Namibia has high potential for rice cultivation because large seasonal wetlands (oshana) form during the rainy season. Evaluating the distribution of surface water would reveal the area potentially suitable for rice cultivation. In this study, we detected the distribution of surface water with high spatial and temporal resolution by using two types of complementary satel...

In 12 patients with severe congestive heart failure (CHF) due to ischemic heart disease or nonischemic cardiomyopathy the hemodynamic response to intravenous infusion of sodium nitroprusside (N) was compared to that of dobutamine (D) 10 microgram/kg/min. D and N produced comparable increases in cardiac output (CO) (2.8 to 5.8 L/min and 2.9 to 5.0 L/min, respectively), but, compared to N, D caus...

The wave of electricity market restructuring both within the United States and worldwide has brought the issue of horizontal market power to the forefront. Traditionally, estimation and prediction of market power has relied heavily on concentration measures. In this paper, we discuss the weaknesses of concentration measures as a viable measure of market power in the electricity industry, and we...
