OBJECTIVE To compare the effect of dextrose prolotherapy on pain levels and degenerative changes in painful rotator cuff tendinopathy against 2 potentially active control injection procedures. DESIGN Randomized controlled trial, blinded to participants and evaluators. SETTING Outpatient pain medicine practice. PARTICIPANTS Persons (N=73) with chronic shoulder pain, examination findings of...

OBJECTIVE Nowadays, many infertile couples can have child by assistant reproductive technology (ART). Always the undesirable effects of these methods on newborn are considered and are evaluated. The aim of this study is to describe the impact of ART on ocular and visual performances of infants born by these methods. MATERIALS AND METHODS In a cross-sectional descriptive study, 479 infants age...

Compared with common dust storms, saline dust storms transport high concentrations of fine-grain saline and alkaline material. The saline dust storm differs from common dust storm, especially considering the sources of the suspended particulate matter (PM), chemical composition, grain size, and circulation processes. Atmospheric particulate matters (TSP, PM10, PM2.5, and PM1) and their water-so...

A dual formulation for the problem of determining absolute performance limitations on overshoot, undershoot, maximum amplitude and fluctuation minimisation for continuous-time feedback systems is constructed. Determining , for example, the minimum possible overshoot attainable by all possible stabilising controllers is an optimisation task that cannot be expressed as a minimum-norm problem. It ...

In this paper we describe the generation of all nonorientable triangular embeddings of the complete graphs K12 and K13. (The 59 nonisomorphic orientable triangular embeddings of K12 were found in 1996 by Altshuler, Bokowski and Schuchert, and K13 has no orientable triangular embeddings.) There are 182, 200 nonisomorphic nonorientable triangular embeddings for K12, and 243, 088, 286 for K13. Tri...
