     Drought monitoring is a fundamental component of drought risk management. It is normally performed using various drought indices that are effectively continuous functions of rainfall and other hydrometeorological variables. In many instances, drought indices are used for monitoring purposes. Geostatistical methods allow the interpolation of spatially referenced data and the prediction of v...

Background & Aims: People`s health, life expectancy and quality of life have been affected by social determinants of health, significantly. Also, socio-economic factors may affect health expenditure, considerably. This study has evaluated the effects of socio-economic determinants on health expenditure for the low-income urban householdsin the informalsector of employment. Methods: In this stud...

I n recent years, many research activities have focused on design that aims to produce universally accessible systems, taking into account special needs of various user groups. These special needs are associated with many user factors, such as impairments of speech, hearing or vision, cognitive limitations, aging, as well as with various environmental factors [3]. Fields that address this probl...

Let F be a finite real abelian extension of Q. Let M be an odd positive integer. For every squarefree positive integer r the prime factors of which are congruent to 1 modulo M and split completely in F, the corresponding Kolyvagin class κr ∈ F×/F×M satisfies a remarkable and crucial recursion which for each prime number l dividing r determines the order of vanishing of κr at each place of F abo...

The universal character is a generalization of the Schur polynomial attached to a pair of partitions; see [8]. We prove that the universal character solves the Darboux chain. The N -periodic closing of the chain is equivalent to the Painlevé equation of type A N−1. Consequently we obtain an expression of rational solutions of the Painlevé equations in terms of the universal characters. Introduc...

Concepts of the modified and the excess Walden products are introduced and discussed when applied together with the ordinary Walden product. The existence of the universal curves of limiting conductances for electrolytes (or for ions) in a given pair of solvents are further examined for a number of mixtures which include ethanol, 2-propanol, 1,1,1,3,3,3hexafluoro-2-propanol, N,N,-dimethylformam...

The benefits of an integrated geographical information system (GIS) and a geostatistics approach to accurately model the spatial distribution pattern of precipitation are known. However, the determination of the most appropriate geostatistical algorithm for each case is usually neglected, i.e. it is important to select the best interpolation technique for each study area to obtain accurate resu...

A new approach is proposed to the description of thin viscous flows near the edges of a solid surface. For a steady flow, the lubrication approximation and the no-slip condition are assumed to be valid on most of the surface, except for relatively small neighborhoods of the edges, where an universality principle is postulated: the behavior of the liquid in these regions is universally determine...
