background & objectives: oral submucous fibrosis (osmf) is a condition where excessive deposition of dense collagen fibers occurred in the connective tissue of oral mucosa. an alteration of collagen necessitates an in depth understanding of collagen in oral tissues as no breakthrough studies have been reported. therefore the aim was to correlate the clinical, functional and histopathologica...

polyanionic cellulose polymer is used as an additive in drilling mud in order to decrease water loss and mudcake- thickness. in this study effect of bulk and nanosize polyanionic cellulose on water loss and mud-cakethickness in mud drilling is investigated. polyanionic cellulose nanoparticles are made by using of ball milling. size of nanoparticles is measured by particle size analyzer. polyani...

conclusions high prevalence of the increased cimt in patients undergoing cabg highlights the significance of cimt measurement in early diagnosis of the systemic atherosclerosis. moreover, although traditional cardiovascular risk factors were important they could not explain the extension and the severity of cimt. it seems that some ultrasonographic features such as the associated carotid plaque...

membrane distillation has the potential to concentrate solutions to their saturation level, thus offering the possibility to recover valuable salts from the solutions. the process performance and stability, however, is strongly dependent upon the features of membranes applied. in addition, several other parameters, membrane thickness and thermal conductivity significantly affect the process per...

an important issue in power generation and petrochemical industries is the monitoring of pipe wall thickness and corrosion/erosion rate. the pipes are usually subject to erosive and/or corrosive environments and any failure could be catastrophic. while periodic manual ultrasonic thickness measurement is the common practice in many industries, in certain cases, where higher accuracies are requir...

abstract study of turbidity current hydrodynamics plays an important role in increasing the economical life of dams though reduction in sediment accumulation. in the present experimental study, the effect of entrance densimetric froude number of turbidity current in sub and super critical conditions (fr =0.6-3.5) have been tested through effect of channel slope and change related to opening hei...

heat and mass transfer, in this paper, is considered in one-row heat exchanger, that fins are hotter than air flow and water is added to fins. related governing equations are derived by analyzing a two-dimension model in a unique cell of a heat exchange. these equations are numerically solved by finite difference method. heat transfer and efficiency under partially wet surface are calculated by...

purpose the aim of this study was to evaluate predictor variables of race time in female ultra-endurance inliners in the longest inline race in europe. methods we investigated the association between anthropometric and training characteristics and race time for 16 female ultra-endurance inline skaters, at the longest inline marathon in europe, the ‘inline one-eleven’ over 111 km in switzerland,...

background: obesity is a worldwide health problem which is associated with a lot of complications. one of these comorbidities is the metabolic syndrome that is in correlation with abdominal fat thickness and waist circumference. various methods were used to reduce abdominal fat thickness such as liposuction. a noninvasive method is the topical agent. in this study, we investigated the effective...

Background and Aim: Several methods have been suggested to measure gingival thick-ness. This study aimed to assess the reliability of visual assessment of facial gingival biotype of maxillary and mandibular teeth with or without using a periodontal probe in comparison with direct measurement. Materials and Methods: Sixty-seven healthy patients (25 women and 42 men) with a total of 100 hopele...
