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...
W i tzgal l [ 7 L comment ing on the gradient project ion methods of R . Frlsch and J . B . 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...
in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...
From the degree zero part of the logarithmic vector fields along an algebraic hypersurface singularity we identify the maximal multihomogeneity of a defining equation in form of a maximal algebraic torus in the embedded automorphism group. We show that all such maximal tori are conjugate and in one–to–one correspondence to maximal tori in the linear jet of the embedded automorphism group. These...
A fast algori thm for Gaussian eliminat ion over GF(2) is proposed. The proposed algorithm employs binary search technique to locate l s along the colum ns of the large binary matrix being triangular ized. T he algori thm requires 2m 2 + m log211 2m bit operations to triang ularize an II X m matrix on a bit-array with 11 processors and m + 2 + l"log2nl bits of vertica l memory per processor . D...
