OBJECTIVE To assess the distribution of stress produced on TMJ disc by chincup therapy, by means of the finite element method. METHODS a simplified three-dimensional TMJ disc model was developed by using Rhinoceros 3D software, and exported to ANSYS software. A 4.9N load was applied on the inferior surface of the model at inclinations of 30, 40, and 50 degrees to the mandibular plane (GoMe). ...

Understanding the characteristics of non-point sources (NPS) pollutions can provide theoretical support for improving water quality. Siheshui watershed located in south China was selected to explore the characteristics of NPS pollutions in rainfall-runoff process. In this small agricultural watershed, five flood events and one non-flood event were monitored, and the water quantity and quality c...

the activated sludge process is the most widely used biological wastewater treatment for both domestic and industrial plants in the world. one of the drawbacks of conventional activated sludge (cas) processes is high sludge production. excess sludge treatment and disposal currently represents a rising challenge for wastewater treatment plants (wwtps) due to economic, environmental and regulatio...

BACKGROUND Recent prospective data suggest that intake of rapidly digested and absorbed carbohydrates with a high dietary glycemic load is associated with an increased risk of ischemic heart disease. OBJECTIVE We examined whether a high dietary glycemic load was associated with elevated hs-CRP concentrations and whether this association was modified by body mass index (BMI; in kg/m(2)). DES...

 In this work, Fe/TiO2 nanostructured catalyst was prepared using sol-gel method developed by Yoldas and tested in degradation of phenol in water under UV radiation.  The synthesized catalyst was characterized by XRF, XRD, specific surface area and porosimetry, and SEM methods. The porosimetry revealed the mesopore structure of the catalyst. Results of SEM confirmed the nano dispersion of  iron...

In this paper, fatigue strength of the engine damper cap screw bolt is determined. Engine damper cap screw is critical fastener. Critical fastener is a term used to describe a cap screw that, upon failure, causes immediate engine shutdown or possible harm to person. So, determination of fatigue strength is important. S-N method is used for cap screw fatigue strength determination by testing num...

background iron-loaded cardiac complication is the essential cause of mortality in patients with thalassemia. early detection and treatment of cardiac over-load can reduce mortality. objectives the current study aimed to evaluate the relationship between serum ferritin levels and t2* magnetic resonance imaging (mri) of heart and liver and liver iron concentration (lic) to diagnose iron over loa...

Nonspecific antibodies, which are thought to be nonprotective, have been shown to contribute a substantial proportion of the measured concentration in the standardized immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) for pneumococcal polysaccharide capsular antibodies. The presence of such antibodies in human immunodeficiency virus (HIV)-infected persons has not been evaluated. ...
