The karstic Rijab Spring with an average discharge of 3290 l/s is located in the Alvand River basin in the northwest of the Zagros, Iran, which drains Asmari formation. To investigate groundwater flow in the catchment area of the Spring, the physicochemical parameters include major cations and anions, discharge, EC, pH, and temperature were studied from September 2000-2002. The results indicate...

The collapse of exports that has attended the current global economic recession threatens the export-led economic growth of the four Asian dragons. To better understand the economic performances and future prospects of the four dragons, this paper first examines the economic structural changes that have taken place in Hong Kong, China; the Republic of Korea; Singapore; and Taipei,China, as well...

Depletion curves of the areal extent of snow cover are shown to be basic information in a snowmelt-runoff model. Originally developed in European mountain basins, the procedure is now applied to simulate the runoff in the Rocky Mountains with the use of the Landsat imagery and air temperature data. The method requires a proper assessment of the recession coefficient of discharge in a given basi...

statement of the problem: recently allogenic mesenchymal stem cells are proposed to have multipotential progenitor cell capabilities to differentiate into cementoblasts, osteoblasts, and periodontal ligament fibroblasts. purpose: the aim of the present study was to compare the efficacy of human umbilical stem cells cultured on polylactic acid (pla), polyglycolic acid (pga) membrane with pla/pga...

PURPOSE To compare postoperative exodrift of the first unilateral lateral rectus (ULR) muscle recession with the exodrift of the second contralateral ULR muscle recession in patients with recurrent small-angle exotropia (XT). METHODS We evaluated the results of a second ULR muscle recession in 19 patients with recurrent XT with deviation angles under 25 prism diopter (PD), following a first p...

AIMS To compare the postoperative surgical outcomes and the changes in deviation achieved per millimetre of recession in patients treated by graded unilateral medial rectus (UMR) or bilateral medial rectus (BMR) recession for small to large angle esotropia with a minimum follow-up of 6 months. METHODS In a retrospective, consecutive and interventional case series, 102 patients underwent UMR r...

The aim of this study is examine trends in breast and colorectal cancer screening in the U.S. by race, healthcare coverage, and socio-economic status (SES) before the Great Recession (2003-2005), during the recession (2007-2009), and post-recession/Affordable Care Act (ACA) period (2010 - 2012). Data on a representative sample of U.S. adults was obtained from the Behavioral Risk Factor Surveill...

PURPOSE To suggest a surgical normogram for lateral rectus recession in exotropia associated with unilateral or bilateral superior oblique muscle palsy (SOP). METHODS We retrospectively reviewed the charts of 71 patients with exotropia who were successfully corrected over one year. Each patient had undergone unilateral or bilateral rectus recession associated with uni- or bilateral inferior o...

Gingival recession is the displacement of the gingival margin apical to the cemento-enamel junction resulting in the exposure of root surface which puts the patient at risk for dentine hypersensitivity, root caries, abrasion/erosion of roots etc. The etiology can be inflammatory periodontal disease, developmental anatomic abnormalities (aberrant frenal attachment, thin bony plate), toothbrush i...

Aims: to determine the prevalence of gingival recession and dentine hypersensitivity among the study population, and evaluate the distribution of dentine hypersensitivity among various types of teeth in mild, moderate and severe degrees of gingival recession. Relationship between the severity of gingival recession and dentine hypersensitivity was also evaluated. Materials and Methods: Clinical ...
