Background: Anterior crossbite is a case that when upper anterior are positioned palatally than lower teeth in centric occlusion. Orthodontic appliances using expansion screw could be solution for tooth treatment. Purpose: To figure out the optimal fabrication process of orthodontic single screw. Case analysis: Dental laboratory provided maxillary dental appliance with on 21. technician also re...

Given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. This study was conducted during 2012-2013 at the Research Center of Agricultural University of Tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. A...

background: sulfur mustard (sm) is an alkylating agent that has been used as a chemical warfare gas during world war ii and by iraqi army in the iran-iraq conflict between 1983 and 1988. sm can cause serious organ damages especially ocular, neurologic, coetaneous, bone marrow and pulmonary complications. on the other hand dexmedetomidine is a α2 agonist with sedative and analgesic effect with a...

geometrically nonlinear governing equations for a plate with linear viscoelastic material are derived. the material model is of boltzmann superposi¬tion principle type. a third-order displacement field is used to model the shear deformation effects. for the solution of the nonlinear governing equations the dynamic relaxation (dr) iterative method together with the finite difference discretizati...

background detection of fetal dna in maternal blood has been examined by many research groups for a few years; thereby, scientists have a shorter way to take to approach prenatal diagnosis of abnormal pregnancies. the y chromosome sequences have recently become the most common applicable indices for fetal sex determination. objectives we conducted an algorithmic x and y mini-short tandem repeat...

the aim of this study was to examine factors affecting adoption of mini-tuber seed potato. survey research design was used in this study. a sample of 100 potato growers who were informed about mini-tuber was selected and divided into adopter and non-adopter groups. questionnaire was used as the instrument for data collection and was validated by a panel of experts. a pilot study was conducted f...

To evaluate the advantages and efficacy of two point mini plate fixation for the zygomatic complex fractures using lateral eye brow and infra orbital approaches for fixing the fronto zygomatic fracture and infra orbital fracture. The zygomatico-maxillary complex functions as the principle buttress of the face and is the cornerstone to an individual’s aesthetic appearance. The zygomatic complex ...

Two and three dimensional finite element models (FEM) were developed to simulate the behavior of a fractured jaw bone and the fixation materials. Mini-plates with various geometric and material properties and screw combinations were considered. Their effects on the variation of maximum stress contours were investigated. The geometric and material properties of the plate, screw and bone were see...

We carried out a prospective study to assess the value of mini-invasive osteosynthesis with the PerCutaneous Compression Plate (PCCP) in the treatment of trochanteric hip fractures in elderly patients. Sixty five consecutive patients were included, with an average age at surgery of 84.2 years (range : 63 to 99), with more than 93% ASA 2, 3 or 4 patients. No perioperative complications were note...
