OBJECTIVE This study compared the primary stability of two commercially available acetabular components from the same manufacturer, which differ only in geometry; a hemispherical and a peripherally enhanced design (peripheral self-locking (PSL)). The objective was to determine whether altered geometry resulted in better primary stability. METHODS Acetabular components were seated with 0.8 mm ...

Purpose: The aim of this prospective clinical study was to evaluate the survival rates at 12 months of transmucosal implants placed in the posterior mandible and immediately restored with single crowns. Materials and Methods: Thirty ITI dental implants with sandblasted, acid-etched surfaces were placed in 30 patients missing at least 1 mandibular molar and immediately restored if acceptable pri...

in this paper we introduce the notions of uniformly quasi-primary ideals and uniformly classical quasi-primary submodules that generalize the concepts of uniformly primary ideals and uniformly classical primary submodules; respectively. several characterizations of classical quasi-primary and uniformly classical quasi-primary submodules are given. then we investigate for a ring $r$, when any fi...

BACKGROUND The stability of protein drugs remains one of the key hurdles to their success in the market. The aim of the present study was to design a novel nanoemulsion drug-delivery system (NEDDS) that would encapsulate a standard-model protein drug--bovine serum albumin (BSA)--to improve drug stability. METHODS The BSA NEDDS was prepared using a phase-inversion method and pseudoternary phas...

We consider a secondary user (SU) with energy harvesting capability. We design access schemes for the SU which incorporate random spectrum sensing and random access, and which make use of the primary automatic repeat request (ARQ) feedback. We study two problem-formulations. In the first problemformulation, we characterize the stability region of the proposed schemes. The sensing and access pro...

recognizing the advantages of primary care as a means of improving the entire health system, this text comments on reforms of publicly funded primary health centers, and the rapid development of private forprofit providers in sweden. many goals and expectations are connected to such reforms, which equally require critical analyses of scarce resources, professional trust/motivation and business ...

primary colorectal lymphoma (pcl) is a rare condition that accounts for a small percentage of all gastrointestinal (gi) malignancies. there are several reports in the literature regarding the most common features of pcl. however, primary lymphoma in the rectosigmoid junction has been rarely reported. our case was a 67-year-old male who presented with non-specific symptoms of bowel obstruction w...

The primary goal of Federal Reserve monetary policy is to foster maximum long-term growth in the U.S. economy by achieving price stability over time. Price stability will be achieved, according to some definitions, when inflation ceases to be a factor in the decision-making processes of businesses and individuals. Although the Federal Reserve has made considerable progress toward price stabilit...

Building on Evans function techniques developed to study the stability of viscous shocks, we examine the stability of viscous strong detonation wave solutions of the reacting Navier-Stokes equations. The primary result, following [1, 17], is the calculation of a stability index whose sign determines a necessary condition for spectral stability. We show that for an ideal gas this index can be ev...
