The calculation formula for lining water pressure, when integrated with lithostatic pressure in the seepage model, facilitates the computation of the maximum pressure head that the tunnel lining can withstand under different conditions. A tabulation summarizing safe water head heights...
aSteel structure, which has higher bearing capacity, smaller sectional dimension, convenient construction and economical investment, can be abroad used in engineering. However, due to a lot of reasons, the gradual expansion and convergence of the micro-defects lead to the macro deterioration of the...
Proposition 7 If for \(t=0\) the Debt Agency computes the fair value of the portfolio pv(0) using portfolio default probabilities but charges obligors individually by using the idiomatic fundamental pricing formula (13), so that \(pv(0)=I_{F}(0){\tilde{a}}_{W}(0)\), then:...
HAAs—Haloacetic acid, of the general formula CX3COOH, where X is Cl, Br, H or another halide in various combinations, which is a general class of disinfection by-products formed primarily during the chlorination of water containing natural organic matter. When bromide is present, a total of...
[0032] It has been found that it is possible to shield a baby bottle so that it can be heated in a microwave oven to a uniform and safe temperature. The inclusion of a microwave reflector to prevent the lateral penetration of microwave radiation on the upper portion of infant formula resul...
According to the previous research results, based on the engineering geological conditions of the 1611 (3) working face and the force bearing formula of the support (1), it is determined that the forced top setting distance of the high key stratum is 20 m. The hole layout is shown inFigur...
such as the shear strength and the bearing capacity. Besides this, the hydrates will release a substantial amount of gas after decomposition, causing a sudden increase in pore pressure and a decrease in the effective stress of the sediments [6]. Under the action of pore pressure and overburden...
Finally, being a new raw material with unknown behavior in emulsion, in this first approach, it was decided to use 2% of the product to best evaluate the optimal methods of incorporation into the formula. Higher percentages at this stage of the research could compromise the final product, resu...
The adsorption value was calculated using formula (6) and experimental data. Similarly, the adsorption values for models with different permeabilities (70, 500, and 1500 mD) were calculated. For ease of reference, all the results obtained by dynamic adsorption are summarized inTable 7. ...
The following sampling approach and statistical formula has been applied for the sample design: 𝒏=𝒛𝟐.𝒑.𝒒.𝑵𝒛𝟐.𝒑.𝒒+(𝑵−𝟏)𝒆2n=z2.p.q.Nz2.p.q+(N−1)e2 (1) where: n = Sample size; N = Targeted population size; e = Admissible error in the ...
