With the majority of United States Department Agriculture-Natural Resources Conservation Service (USDA-NRCS)-sponsored earthen dams exceeding their planned service life, seepage is a concern since it common failure mechanism among as whole. Seepage occurs when water penetrates hydraulic barrier to create open pathways, channels, or piping leading internal erosion stability issues due increased ...

We show that there may be a Milliken-Taylor ultrafilter with infinitely many near coherence classes of ultrafilters in its projection to ω, answering a question by López-Abad. We show that k-coloured Milliken-Taylor ultrafilters have at least k + 1 near coherence classes of ultrafilters in its projection to ω. We show that the Mathias forcing with a Milliken-Taylor ultrafilter destroys all Mill...

Alzheimer׳s disease (AD) is one of the most common dementias showing slow progressive cognitive decline. Progression of intracerebral accumulation of beta amyloid (Aβ) peptides by the action of amyloid binding alcohol dehydrogenase (ABAD), a mitochondrial enzyme and β-site amyloid precursor protein cleaving enzyme 1 (BACE1) and the degradation of Acetylcholinesterase (AChE) the main pathologica...

The article is devoted to the dynamic problems of studying strain state earth dams under impacts. A method developed for solving wave determine stress-strain structures, in particular, dams. Based on use finite difference method, an algorithm and calculation formulas were that have second-order accuracy time coordinates. advantage implementation complex nonlinear deformation models, taking into...

Large dams, especially concrete dams, have been designed against earthquakes since the construction of Hoover dam in the 1930s. The design criteria and methods of analysis used in those times are outdated today and the actual seismic safety of these structures is not known in view of today’s requirements. Earthquake action was usually taken into account pseudostatically, through an inertia forc...

The design of dams requires comprehensive studies to ensure the safety and feasibility these important engineering projects, as any possible failure case may lead considerable losses in human life properties. Specifically, analyses should be performed evaluate seepage, slope stability, soil liquefaction large earth dams. In this study, numerical modeling, based on finite element methods, was us...

Neurotoxicity of beta-amyloid peptide (A beta) in Alzheimer's disease (AD) is usually thought to arise from the nonspecific effects of high concentrations of A beta on vulnerable neurons, resulting in membrane destabilization and increasing intracellular calcium concentration. This review advances the hypothesis that at early stages of AD, when A beta is present in lower amounts, its ability to...

Historically, the occurrence of dam-break cases has been proven to cause significant loss life and economical damage. Apart from catastrophic nature dam-breaks, absence a robust disaster prevention system exacerbates disasters that occur. This study proposes an Early Warning System (EWS) mitigate impact disasters. However, predicting such is challenging, specifically in areas like Indonesia, wh...

Aging earth fill dams that were constructed in the mid-1950’s are beginning to show signs of instability associated with time-dependent degradation shear strength. The strength can be attributed fissures, leaching cementation, and creep highly plastic clays, among other issues. processes being examined an dam experienced slope but did not result a loss water. This paper discusses research findi...
