Digital preservation ensures continued access to digital information over time (e.g., 5, 15, 25 or 50 years). The long-term planning horizon of preserving relevant parts of a business processes raises a number of new research challenges for software design, development and maintenance (cf. [1]). In this paper we describe the challenges caused by the preservation of software and give a short ove...

premature ejaculation (pe) is one of prevalent male sexual dysfunctions worldwide. despite many psychiatric backgrounds, yet there are speculations about organic etiologies considering both anatomic and physiologic points of view. this survey assesses effect of frenular web preservation on premature ejaculation. one thousand and forty otherwise healthy men being visited for urolithiasis (asympt...

Trehalose-glycerol mixtures are known to be effective in the long time preservation of proteins. However, the microscopic mechanism of their effective preservation abilities remains unclear. In this article we present a molecular dynamics simulation study of the short time, less than 1 ns, dynamics of four trehalose-glycerol mixtures at temperatures below the glass transition temperature. We fo...

there are two methods for identifying formation interface in oil wells: core analysis, which is a precise approach but costly and time consuming, and well logs analysis, which petrophysists perform, which is subjective and not completely reliable. in this paper, a novel coupled method was proposed to detect the formation interfaces using gr logs. second approximation level (a2) of gr log gained...

This study models a joint pricing, inventory, and preservation decision-making problem for deteriorating items subject to stochastic demand and promotional effort. The generalized price-dependent stochastic demand, time proportional deterioration, and partial backlogging rates are used to model the inventory system. The objective is to find the optimal pricing, replenishment, and preservation t...

INTRODUCTION The solution in which graft tissue is stored (that is, preservation solution) is an important component of liver transplantation technology. Its protective effect is induced by substances in the solution, including radical scavengers, buffers, and energy-giving substances. New preservation solutions have proven to be effective in preventing organ damage during cold ischemia and in ...

Objective To review and assess the ideal length of electrode in cochlear implant patients for hearing preservation. Methods The English language literature was reviewed for studies including hearing preservation and speech understanding for electrodes of different lengths. Results One prospective trial was found, and there were no studies that randomized patients into different length elect...
