A particular river-whiting phenomenon occurred in the early 2000s in the Xiaoche River and since then it has been reoccurring from June to November each year. Residents were surprised by this phenomenon and worried about it. This study was designed to reveal the forming mechanism of the river-whiting phenomenon. A comparison of T, EC, ORP, DO, TDS and δ34S in the culvert water and discharge pip...

In December 2008, near Flaming Gorge Reservoir in northeastern Utah, a 2 1⁄2-yearold male Rocky Mountain bighorn sheep (Ovis canadensis canadensis) was reported in poor body condition with bloody lesions covering the muzzle area. The sheep was euthanized, and samples were submitted to the Utah Veterinary Diagnostic Laboratory in Logan, Utah. The gross and microscopic lesions confi rmed the diag...

Recent developments allow high-pressure mercury intrusion experiments to be performed under reservoir-representative confining stress. NMR relaxation measurements on core samples are increasingly being used in addition to mercury intrusion data since the two techniques yield complementary information about the pore network. Integration of the different measurement techniques result in a more de...

The changes occurring during aging of reservoir core samples in crude oil, which aims to restore the reservoir wettability, are complex. The dynamic mechanisms involved are still not entirely clear. Understanding the dynamics of wettability restoration in the laboratory will improve our ability to reproduce reservoir conditions before performing core tests and help to ensure that laboratory dat...

Dams are very important in Ghanas economic development and environmental improvement. Although Ghana dams seismically far from the active zone, accurately analysed should be evaluated since failure could severely impact people flood environment regions economy on a large scale. This paper proposes numerical procedure for static, slope stability, dynamic analysis of Akosombo embankment dam. Nine...

Coordination in circular and longitudinal muscle motions are of crucial importance in the motor function of gastrointestinal (GI) tract. Intestinal wall motions depend on myogenic-active properties of smooth muscles layers of intestinal wall, which is the ability to create active contractile forces in response to distension. Considering the stress in the circular and longitudinal smooth muscles...

Reservoir modeling is the process of generating numerical representations of reservoir conditions and properties on the basis of geological, geophysical, and engineering data measured on the Earth’s surface or in depth at a limited number of borehole locations. Therefore, reservoir modeling requires an incorporation of the data from a variety of sources, along with an integration of knowledge a...

The probability distribution of a function subsystem conditioned on the value whole, in limit when ratio their values goes to zero, has law: It equals unconditioned marginal weighted by an exponential factor whose exponent is uniquely determined condition. We apply this theorem explain canonical equilibrium ensemble system contact with heat reservoir. Since only requires analysis at level and r...

C oilfield is a heavy oil field developed by horizontal wells and single sand body in Bohai oilfield. The edge bottom water of the reservoir active natural energy development mode adopted. comprehensive cut was 95.3%, which had entered stage high production. Some reservoirs were limited crude viscosity column height. Under condition existing well pattern, some reserves not produced or degree pr...
