in this paper we provide‎ ‎existence results for positive solution to‎ ‎dirichlet p(t)-laplacian boundary value problems‎. ‎the sublinear and‎ ‎superlinear cases are considerd‎.

the genetic constitution of the implant itself as well as the relative stages of development of implant and host may also influence this property of autonomy or non-autonomy of the implant. As a concluding example, we shall mention briefly, experiments made to establish the time in development at which vermilion pigmentation is irreversibly determined, i.e., after which a vermilion eye disc imp...

This article is an overview of the recent developments of a theory originally introduced by Leifer and Milner: given a formalism with a reduction semantics, a canonical labelled transition system is derived on which bisimilarity as well as other other equivalences are congruences, provided that the contexts of the formalism form the arrows of a category which has certain colimits. We shall also...

Managers of service organizations seek to improve productivity without eroding service quality. We explore whether privately versus publicly disclosing relative performance feedback (RPF) about individual workers’ processing times can help achieve this goal. Using three years of patient encounter data from two emergency departments, one of which changed from privately to publicly disclosing RPF...

To elucidate the mechanism of mobilization of insoluble phosphates, a field trial and a split root experiment in a growth chamber were conducted. The results showed that a phosphorus (P)-efficient wheat genotype, Yanzhong 144 (YZ), transpired 50% less than a P-inefficient genotype, 80-55. At the grain-filling stage, the free water content in YZ’s rhizosphere was 2.4 times of that of 80-55’s. Wh...

introduction: evaluation of human resources requires proper indicators for its performance measurement. in fact, compiling indexes consider as the basic source of information evaluation. the aim of this study was to compiling the basic human resources indicators in health system to provide enough information to evaluate human resource management in this sector. this work developed by designing ...
