a study was conducted to investigate the effect of follicular size (small,
background and aims. in contrast to prepared natural dentin abutments, little is known concerning factors influencing the retention of fixed prostheses cemented to implant abutments. the aim of this study was to investigate the effect of implant abutment height on the retention of single castings cemented to wide and narrow platform implant abutments. materials and methods. thirty-six parallel-...
This study investigated the effect of rate and type of organic matter, and consecutive application of sodium on secondary particle size distribution. At first, a cropland soil was treated with two organic matter (manure and straw stubble) at different rates of 0%, 1% and 5%, with three types replicates during 4 months. Subsequently, four levels of SAR (0, 1, 10 and 30) were added to the pretrea...
Many research studies have been conducted on the liberation of locked minerals using a crusher and comparing this device with the other devices. This paper reviews the liberation of middle coal by different methods of crushing force. In the Tabas coal washing plant, particles of 0.5-50 mm size are processed through the heavy media method (using 3 Tri-flo separators) and particles of 0-0.5 mm si...

background: immune system disturbances have an important role in endometriosis which may lead to infertility. it seems that inflammatory cytokines specially tumor necrosis factor alpha (tnf-) which were produced by activated macrophages have an important role in pathology of endometriosis. based on this theory, anti tnf- drugs like pentoxifylline (px) are suggested as new drugs for endometrio...
background: tonsilloliths are calcified concretions that develop in tonsillar crypts. they are usually small and asymptomatic, so they are found accidentally during routine dental radiogrphy procedure. large tonsilloliths can occur with clinical signs and symptoms. the purpose of this study was to evaluate the prevalence and patterns of palatine and adenoid tonsilloliths in cone‑beam computed t...
Saturated hydraulic conductivity (Ks) is one of the most important soil physical characteristics that plays a major role in the soil hydrological behaviour. It is mainly affected by the soil structure characteristics. Aggregate size distribution is a measure of soil structure formation that can affect Ks. In this study, variations of Ks were investigated in various aggregate size distributions ...
introduction & objective: in vitro studies shown the effect of zinc sulfate on healing of ulcers but limited in vivo studies have been done to demonstrate this effect in human. this study was conducted to investigate the effect of zinc sulfate on peptic ulcer disease materials & methods: this is a double blind randomized clinical trial study. we studied people who referred to endoscopy clinic i...
