conclusion the cv value correlated more closely with low lvef and more accurately indicated an enlarged heart than ca or ctr. this may be due to the fact that an anteroposterior measurement of heart size is included in the former but not the latter two measurements. these study results may help quantify left heart enlargement with greater accuracy than may be obtained from standard cxr. backgro...

in this article cuo/water nanofluid was synthesized by using polyvinylpyrolidone (pvp) as the dispersant.  thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. to study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different ph values and pvp surfactant concentrations; also thermal conductivity...

We review the new proposed End-System Method 1 for Use-it-or-lose-it behavior proposed in Annex F of the Traac Management Speciication Version 4.0, R10, for bi-directional TCP traac. We have studied this in an environment of explicit rate switches. This contribution is a follow-up to the work discussed in ATM Forum/95-1598. to the ATM Forum as a basis for discussion and is not a binding proposa...

This paper identifies pivotal factors behind individual decision-making in the transition from high school to post-secondary education in the Netherlands. We apply a multinomial logit framework to individual data on post-secondary education choices. Specifically, our modeling approach accommodates two types of effects that have not received ample attention in the literature. First, we include i...

In the internet environment, it is desirable for a user to login different servers by keying the same password and using the same smart card. This paper proposes an authentication and key agreement scheme with key confirmation for multi-server environments. Compared with the previous authentication and key agreement schemes for multi-server environments, the new scheme holds many merits. It sat...

A bank of gonococcal DNA was constructed in the lambda gt11 expression vector. immunological screening of the bank resulted in the isolation of a clone that contains the structural gene of protein III. In addition, several clones reactive with mAbs specific for the H8 antigen were isolated. DNA hybridization studies revealed that these H8-reactive clones were derived from three different gonoco...

This paper obtains an evolving pattern of goods market integration in Russia, considering the period of economic upturn, since the second half of 2000 through the end of 2007. In an integrated market, the price of a tradable good at any location is determined by the national market, not local demand. Based on this, the strength of dependence of local prices on local demands is used to detect an...

Let Ci (i = 1, ..., N) be the i-th open spherical cap of angular radius r and let Mi be its center under the condition that none of the spherical caps contains the center of another one in its interior. We consider the upper bound, rN, (not the lower bound!) of r of the case in which the whole spherical surface of a unit sphere is completely covered with N congruent open spherical caps under th...
