Research on Water Velocity in Filling up Section of Horizontal Pipe

Wang Dongmei,Zhang Shilin

Strategic Study of CAE 2005, Volume 7, Issue 2, Pages 66-68

Abstract:

The article divides the whole section into two sections. One is arcuate section. The other is seepage section. Water velocity distribution in circular section of pipe has been studied for a long time, and advanced theories were achieved. Based on fore theory and some tentatives, theory about distribution of water velocity in pipe of arcuate section is researched. Research of seepage section is based on seeping theory. Many experiments proved that the theory and program of this article are correct.

Keywords： arcuate section filling up bed water velocity zero shear point water-power gradient

Evaluation method of dam behavior during construction and reservoir filling and application to real dams

Yuji KOHGO, Akira TAKAHASHI, Tomokazu SUZUKI,

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 1, Pages 92-101 doi: 10.1007/s11709-010-0009-2

Abstract: In this paper we analyzed a real fill-type dam, named the Minami-Aiki Dam, to verify a numerical consolidation method with an elastoplastic model for unsaturated soils. The validities were conducted by comparing the analyzed and measured values during construction and impounding. The settlements calculated showed good agreement to those observed. Though the changing patterns of the measured and calculated pore water pressures were similar, the amounts of pore water pressures induced by the self-weights of embankment and the dissipation speeds were different. The earth pressures measured at the bottom of the core zone showed good agreement with those calculated. This method is valid for estimating behavior of fill-type dams during construction and impounding.

Cancer and the environment: Filling knowledge gaps together

Linda S. BIRNBAUM PhD, DABT, ATS,

Frontiers of Medicine 2010, Volume 4, Issue 2, Pages 131-133 doi: 10.1007/s11684-010-0044-3

Abstract: When considering disease etiology, we need to view the role of the environment along the continuum from health to disease for individuals because we know that there are complex interactions between genes, their molecular expression, and environmental factors over a person’s lifetime. We clearly have huge gaps in our knowledge along this continuum, and these gaps are natural opportunities for research. There are many factors to consider as we assess the relationship between environmental exposures over a lifetime. One factor is persistence of chemicals that “live” beyond their initial intended use. Another factor is the fact that “inert ingredients” are not really inert. “Low dose” is also another consideration. We need to understand the biological effect of low dose exposure and we should clearly define what they mean by low dose research. For example, are we measuring the administered dose, or the internal/circulating dose? There are new types of toxicity as well. For example, endocrine disruptors and engineered nanomaterials are significant classes of materials deserving significant research. Timing of exposure is a significant feature in characterizing toxicity. Environmental exposures can have a greater impact in early or later life-stages. Finally, mixtures of chemicals are an important consideration. Humans are always exposed to multiple chemicals. In short, we must remember that there is no such thing as “not exposed.” Everyone has been exposed to many and various environmental agents.
