For processes such as water injection in deep geothermal production, heat transfer and fluid flow are coupled affect one another, which leads to numerous challenges wellbore structure safety. Due complicated structures, consisting of casing, cement sheaths, formations under high temperature, pressure, situ stress, the effects thermo-hydro-mechanical (THM) coupling crucial for instability contro...

We show that a maximal curve over Fq2 defined by the affine equation y = f(x), where f(x) ∈ Fq2 [x] has degree coprime to n, is such that n is a divisor of q+1 if and only if f(x) has a root in Fq2 . In this case, all the roots of f(x) belong to Fq2 ; cf. Thm. 1.2, Thm. 4.3 in [J. Pure Appl. Algebra 212 (2008), 2513–2521]. In particular, we characterize certain maximal curves defined by equatio...
BACKGROUND Evidence on the association between colorectal cancer and exposure to disinfection by-products in drinking water is inconsistent. OBJECTIVES We assessed long-term exposure to trihalomethanes (THMs), the most prevalent group of chlorination by-products, to evaluate the association with colorectal cancer. METHODS A multicenter case-control study was conducted in Spain and Italy in ...
The growth of (Cd,Zn)Te (CZT) crystals and the improvement crystal quality are part a research project towards experiments under microgravity using Traveling Heater Method (THM). In order to determine experimental parameters, we performed detailed ground-based program. Three CZT with nominal Zn content 10% were grown THM from Te-rich solution. size distribution Te inclusions evaluated by transm...

Rosen , states: "More or less a l l algori thms for solving the l inear programming problem are known to be modificat ions of an algori thm for matrix inversion . Thus the simplex method corresponds to the Gauss-Jordan method . The methods of Frisch and Rosen are based on an interest ing method for inver...
The presence of trihalomethanes (THMs) in drinking water has attracted the attention of both researchers and professionals, because of the harmful effects of these substances on human health. A multiple regression model was developed to estimate THM concentrations in finished drinking water, using data from the Menidi Treatment Plant of Athens. A number of routinely measured characteristics--in...
As already done for the matrix case in [6, p.256], [1, Thm. 6.1, p.1872] and [10, Thm. 3.2] we give a parametrization of the Bouligand tangent cone of the variety of tensors of bounded TT rank. We discuss how the proof generalizes to any binary hierarchical format. The parametrization can be rewritten as an orthogonal sum of TT tensors. Its retraction onto the variety is particularly easy to co...
Thermo-hydro-mechanical (THM) densification is a well-known procedure for improving the properties of low-density wood species, but long-term behaviour densified under constant load has not been reported and may restrain its use in construction. This study investigated influence THM on creep bending beech pine climatic conditions. The specimens were loaded three-point at applied stress level 35...
