Dry socket/alveolar osteitis is a very debilitating, severely painful but relatively common complication following dental extractions. Its incidence is approximately 3% for all routine extractions and can reach over 30% for impacted mandibular third molars. A number of methods have been suggested in the literature as to how this condition may be prevented and managed. Most of these suggestions ...

The breakdown strength characteristic of Low Density Polyethylene films (LDPE) under DC voltage application and the effect of water absorption have been studied. Mainly, our experiment was investigated under two conditions; dry and heavy water absorption. Under DC ramp voltage, the result found that the breakdown strength under heavy water absorption has a lower value than dry condition. In ord...

The friction and wear properties of polyamide 66 (PA66), polyphenylene sulfide (PPS) and polytetrafluoroethylene (PTFE) sliding against hemselves under dry sliding and oil-lubricated conditions were studied by using a pin-on-disc tribometer. The effect of applied load and sliding peed on tribological behaviors of the polymer–polymer sliding combinations under dry sliding and oil-lubricated cond...

Gizzard shad (Dorosoma cepedianum) were collected from four locations in western Lake Erie during summer, 1982. The nutritional quality of foods ingested by these fish was examined. Small (<60 mm standard length), age 0 fish consumed mostly zooplankton with high organic (>80% of dry weight) and nitrogen (>6% of dry weight) contents. The phytoplankton and detritus diets of larger, age 0 and adul...

This paper focuses on studying the improvement in the performance of Ethylene Propylene Diene Monomer (EPDM) which is used as outdoor high voltage insulating material by adding ATH filler. The study undertakes an investigation of the dry band arcing characteristics of the composite under un – aging condition. Also the dry band arcing characteristics of the composite have been studied under the ...

This study evaluated the influence of curing method and storage condition on the microhardness of dual-cure resin cements: Panavia F 2.0 (PF) and Nexus 2 (NX). The specimens were either light-cured (LC) or chemically cured in darkness (CC). After 24 hours of storage in dry chamber (Dry) or distilled water (DW), the specimens were sectioned and polished. The microhardness of resin cement matrix ...

The physical properties and shear bond strength of two resin-modified glass-ionomers: RMGIs (FJL and VT) and as a control, a conventional glass-ionomer: CGI (FJ), were evaluated. Ninety percent of the setting shrinkage under dry conditions and nominal hygroscopic expansion in water during 360 h occurred within the first 24 h. The nominal hygroscopic expansion of CGI was 0.38% while the RMGIs de...

stem reserves of barely can be an important contributor to grain filling particularly under condition is limited such as salinity stress. the aim of this research was to study dry matter accumulation and remobilization ability in different internodes of some iranian barley varieties and promising lines under salinity and normal conditions. the research was set up as two randomized complete bloc...

A robust numerical method for saturated-unsaturated flow is developed which uses a monotone discretization and variable substitution. This method is compared to a conventional formulation and to a two phase (active air phase) model. On some published test examples of infiltration into dry media, the variable substitution method shows an order of magnitude improvement (in terms of nonlinear iter...
