OBJECTIVES There are conflicting data on using the Cockroft-Gault formula and the Modification of Diet in Renal Disease formula to assess graft function in kidney transplants. This study uses a cohort of Jordanian kidney transplant patients to assess performance of the Cockroft-Gault formula and the Modification of Diet in Renal Disease equations by using the criterion standard of measured crea...

The paper presents the method of signature recognition, which is a modification of the windows technique. This windows technique allows comparing signatures with the use of any similarity coefficient, without the necessity of using additional algorithms equalizing the lengths of the sequences being compared. The elaborated method introduces a modification regarding the repeatability of individu...

The authors recently proposed a simplex-based Tardos’ algorithm which is strongly polynomial if the coefficient matrix is totally unimodular and the auxiliary problems are non-degenerate. Motivated by the algorithmic practically of such methods, we introduce a modification which circumvents the determination of the largest sub-determinant while keeping the same theoretical performance. Assuming...

In this study, the aerodynamic analysis of Ahmed body which is generic automobile model performed to determine convenient turbulence and reduce drag coefficient by modifying shape model. For purpose, Computational Fluid Dynamics (CFD) carried out using different models that are Spalart-Allmaras, (Shear Stress Transport) SST k-ω, Standard k-ε, Realizable (Re-Normalisation Group) RNG k-ε models. ...

An efficient initial approximation method for multiplicative division and square root is proposed. It is a modification of the piecewise linear approximation. The multiplication and the addition required for the linear approximation are replaced by only one multiplication with a slight modification of the operand. The same accuracy is achieved. The modification of the operand requires only a bi...

The current practices used in tube drainage design often lead to unsatisfactory results : from the point of view of the system's hydraulic performance, or from the point of view of high cost of the system in relation to the actual economic benefits derived from it. It is proposed therefore, that the design of tube drainage systems should be based on a synthesis of experimental field results, an...

allocation and removing of excess water from the irrigation and drainage network is one of the most important activities in the management of these networks. side weir is one of the most common structures for this purpose. study on the flow hydraulic characteristics of this structure included two parts, defining the water surface profiles and estimating the discharge coefficient. to estimate th...

Due to the scarcity of water resources, there is a need for an additional source irrigation. Drainage waters can serve as such sources. To use these waters, it necessary develop number measures. The aim study reduce negative consequences by increasing norms preventive It vital fulfilling tasks set: calculation supply rates and irrigation regime when designing drainage As result field studies ac...
