A randomized uniform self-stabilizing protocol that provides each (anonymous) processor of a uniform system with a distinct identiier is presented. The protocol uses a predeened xed amount of memory and stabilizes within expected (d) time, where d is the actual diameter of the network.
Strong foam can be generated in porous media containing oil, resulting in incremental oil recovery; however, oil recovery factor is restricted. A large fraction of oil recovered by foam flooding forms an oil-in-water emulsion, so that costly methods may need to be used to separate the oil. Moreover, strong foam could create a large pressure gradient, which may cause fractures in the reservoir. ...
BACKGROUND An aerosol foam formulation of fixed combination calcipotriene 0.005% (as hydrate; Cal) plus betamethasone dipropionate 0.064% (BD) was developed to improve psoriasis treatment. OBJECTIVES To compare the efficacy and safety of Cal/BD aerosol foam with Cal/BD ointment after 4 weeks. METHODS In this Phase II, multicenter, investigator-blind, 4-week trial, adult patients with psoria...
BACKGROUND Hydrocellular foam dressing, modern wound dressing, induces moist wound environment and promotes wound healing: however, the regulatory mechanisms responsible for these effects are poorly understood. This study was aimed to reveal the effect of hydrocellular foam dressing on hyaluronan, which has been shown to have positive effects on wound healing, and examined its regulatory mechan...
AIMS AND OBJECTIVES The aim of this study is to compare whether differences exist between 2 viscoelastic foam support surfaces in the development of new pressure ulcers. BACKGROUND There is evidence to support the use of viscoelastic foam over standard hospital foam to reduce pressure. A comparative effectiveness study was done to compare 2 viscoelastic foam support surfaces. DESIGN A rando...
in the present paper, a landslide and its stabilization is studied on a slope of tabriz northern freeway. this landslide is a large scale one, and as the study zone has a sliding potential so that its study is quite necessary. the analysis of landslide has been performed using stabl software. the way of obtaining the critical slope for land slide amongst different sections and determining a suc...
Abstract We describe here the quasi-static crushing behavior of novel classes multiphase (hybrid) hierarchical lattice metamaterials. The first class is represented by a hybrid architecture combining honeycomb with polyurethane foam filler, while second structure produced injecting an alginate hydrogel into voids metamaterial. Twelve different auxetic (i.e. negative Poisson’s ratio) and non-aux...
BACKGROUND Foam sclerotherapy (foam) and endovenous laser ablation (EVLA) have emerged as alternative treatments to surgery for patients with varicose veins, but uncertainty exists regarding their effectiveness in the medium to longer term. OBJECTIVES To assess the clinical effectiveness and cost-effectiveness of foam, EVLA and surgery for the treatment of varicose veins. DESIGN A parallel-...
Phase Change Materials (PCMs) has gained considerable interest for storing thermal energy originating from the solar irradiation, industrial waste heat and surplus heat. Here, we present facile scalable synthesis of PCM-carbon foam composites by using polyisocyanurate (PIR) derived carbon as porous support. The unique 3D molecular configuration materials embedded with high PCM loading capacity,...
