background: chronic kidney disease is a progressive and irreversible loss of renal function. anemia is one of the main complications of end-stage renal disease (esrd) which is linked closely with other complications of the disease. the primary therapy for anemia in these patients is erythropoietin (epo). the goal of this study was to find the effect of vitamin d administration in addition to th...

Two maize genotypes differently responsive to nitrogen availability were characterized for their ef®ciency in nitrate accumulation via both the LATS (LowAf®nity Transport System) and HATS (High-Af®nity Transport System) nitrate uptake systems. In addition, a full-length cDNA encoding a putative highaf®nity nitrate transporter (ZmNrt2.1) was isolated and its expression evaluated in both the root...

Performance measurement is the basis of management with regard to controlling activities of an enterprise. Development of appropriate indicators and measurement techniques lead to many problems. Th e majority of enterprises begin to evaluate the effi ciency, by the implementation of fi nancial indicators that are practically incalculable. Only at a later stage, are measures used that are relate...

This paper explores the use of the optimisation procedures in SAS/OR software with application to the measurement of e#ciency and productivity of decision-making units (DMUs) using data envelopment analysis (DEA) techniques. DEA was originally introduced by Charnes et al. [J. Oper. Res. 2 (1978) 429] is a linear programming method for assessing the e#ciency and productivity of DMUs. Over the la...

This paper describes a construction and characteristics of a coal-gas-burning high e ciency power plant which emits no carbon dioxide (CO 2 ) into the atmosphere. In the plant, CO 2 gas and superheated steam are used as the main and sub working uid, respectively, of a closed dual uid gas turbine power generation system. It is assumed that a coal gas whose principal compositions are CO, H 2 , CO...

Given the knowledge that the ischiocavernous and bulbocavernous muscles are involved in the erection of the penis, we studied the voluntary contractile activity of the perineal ̄oor muscles in sexually potent and impotent men to investigate whether or not a different muscular ef®ciency can be found in these subjects. The activity of perineal ̄oor muscles was studied in 76 sexually potent men and ...

Introduction Vitamin B12 defi ciency in infants can result in profound and permanent health consequences. Prevention, early diagnosis and early treatment are crucial to ensure a better outcome for those affected.1 However, the symptoms of vitamin B12 defi ciency in infants can be non-specifi c, leading to delayed or missed diagnosis. Vitamin B12 (cobalamin) is a water-soluble vitamin found natu...

This research aims at creating and providing a framework to describe algorithmic redistribution methods for various block cyclic decompositions. To do so properties of this data distribution scheme are formally exhibited. The examination of a number of basic dense linear algebra operations illustrates the application of those properties. This study analyzes the extent to which the general two-d...

The aim of this study is to analyze the robustness of the three major airline alliances’ (i.e., Star Alliance, oneworld and SkyTeam) route networks. Firstly, the normalization of a multi-scale measure of vulnerability is proposed in order to perform the analysis in networks with di↵erent sizes, i.e., number of nodes. An alternative node selection criterion is also proposed in order to study rob...

In this work, we investigate two issues that are important to computational e ciency and reliability in uid dynamics applications of the lattice Boltzmann equation (LBE): (1) Computational stability and accuracy of di erent lattice Boltzmann models and (2) the treatment of the boundary conditions on curved solid boundaries and their 3-D implementations. Three athermal 3-D LBE models (D3Q15, D3Q...
