On the other hand, for the melt spinning of polyolefins such as PE and PP, and especially for the polymers with branching or a wide molecular weight distribution, the use of a viscoelastic model is recommended, even for extremely low take-up velocities. Various differential-type constitutive ...

What is normal force in physics? Normal force is a contact force applied by a surface on an object. It can be calculated through the application of Newton's Second Law, and its direction is opposite to the weight of one of its components. The normal force always has a 90-degree angle ...
In the very simplest case, P1 is zero at the top of the fluid, and we get the familiar relationship P = ρgh. (Recall that P = ρgh and ΔPEg=mghΔPEg=mgh) Bernoulli’s equation includes the fact that the pressure due to the weight of a fluid is ρgh. Although we introduce ...
Intrauterine infection and the risk of cerebral palsy in very low-birthweight infants Very low-birthweight infants constitute more than one-quarter of all new cases of cerebral palsy. We performed a case-control study of associations between... O'Shea,TM,Klinepeter,... - 《Paediatric & Perina...
We also note that we have the a priori bound δn(s)≤2MSn(2ℓ), where Sk is defined as the supremum of the inverse weight in the centered k-ball: Sk=sup|x|∞≤kΦ(x)−1=sup|x|∞≤k⟨x⟩1/2≤cd⟨k⟩1/2. (5.7) This will be useful after we have iterated the...
The Clausius-Clapeyron equation may be used for calculating any of the quantities entering into the equation if the remaining quantities are known. In particular, the equation is used for calculating the heats of evaporation, which are difficult to determine experimentally. ...
The results are also compared and in good agreement with exact diagonalization. We also find a different picture of the spectral weight transfer than the iterative perturbation theory. 展开 关键词: strongly correlated electron systems dynamical mean field theory quantum impurity model equation of motion...
The number sought could be the square root of a given number, the weight of a stone, or the length of the side of a triangle. Many of the questions were phrased in terms of concrete situations—such as partitioning a field among three pairs of brothers under certain constraints. Still, ...
