Clogging occurs during mechanical tunneling with a Tunnel Boring Machine (TBM) because of adhesion of clayey soils to the cutterhead and conveyor system. The present study examined the effects of water and sand contents on clogging in Montmorillonite clayeysoil. Testing was carried out using an adhesion test device on 28 samples with different water and sand contents to determine adhesionstress...
background there is a dearth of epidemiologic studies that provide important information to understand the incidence, prevalence and severity of oral lesions in patients with tuberculosis (tb). objectives this study aimed to determine the prevalence of oral mucosal lesions and adverse habits among hospitalized tb patients. patients and methods the study was conducted on all the tb patients (n =...
Background and Objective: Adhesion formation is the commonest complication of abdominal surgery. Bearing an anti-oxidant activity, Silybum marianum may reduce adhesion formation. This study was an endeavor to shed light on the effect of Silybum marianum on intra-abdominal adhesions. Materials and Methods: In this experimental study, 30 rats were randomly assigned to three groups: treated by ...
background: the health risks of crack cocaine smoking on the oral mucosa has not been widely researched and documented. objective: the purpose of this study was to analyze the proliferative activity of oral epithelial cells exposed to crack cocaine smoke using silver nucleolar organizer region (agnor) staining. methods: oral smears were collected from clinically normal-appearing buccal mucosa b...
background: in this experimental study, the radiographic and biomechanical characteristics of osteoperforated rabbit tibia during bone repair period were investigated. materials and methods: using dental drills, 2 mm holes were drilled at the mid-shaft of right tibia in 12 new zealand white rabbits. the left tibia was intact and selected as the control. x-rays of the left and right tibias were ...
In Vitro Effects of Four Porcelain Surface Treatment Methods on Adhesion of Lactobacilli Acidophilus
Objective: Adhesion of Lactobacillus acidophilus (L. acidophilus) to dental porcelain surface may lead to gingival inflammation and secondary caries. Surface roughness is among the factors affecting this adhesion. The purpose of this study was to evaluate the effects of four different surface treatment methods on adhesion of L. acidophilus to dental porcelain. Methods: Sixty specimens (3x10...
Keratocystic odontogenic tumor (KCOT) is a benign intraosseous neoplasm of the jaw occurring most commonly in mandibular ramus molar area with male predilection. Peripheral KCOTs are very uncommon. Here we report a case of keratocyst in buccal mucosa in a 55 years old female patient, the diagnosis of which was based on subjective histological evaluation and further confirmed by immunohistochemi...
Cu-Mo and Cu-Ti contact structures were fabricated on multi-crystalline silicon substrates to provide a low resistance ohmic contact. Deposition steps are done in an excellent vacuum chamber by means of electron beam evaporation and samples are then annealed for the realization of an efficient alloy layer. The effects of process parameters such as film thickness, annealing duration and temp...
Background and aim: Lichen planus (LP) is a chronic inflammatory disease with an uncertain pathogenicity. Recent reports have revealed that angiogenesis is effective in the pathogenesis and biologic behavior of lesions. Considering the limitations of the studies related to angiogenesis in oral LP (OLP) and the controversial results, the present study aimed to compare the expression of vascular ...
DYOPTYKA’s innovative solution for the reduction of speckle noise in projection displays, using a phase randomizing deformable mirror, is shown to achieve good performance both within a single 1 μs pulse duration and through sequences of such pulses.
