dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...

bronchiolo-alveolar carcinoma with subcutaneous chest wall metastasis is a very rare presentation. a case of 36- year-old male with metastatic subcutaneous chest nodule of bronchiolo-alveolar carcinoma, diagnosed by fine needle aspiration cytology, is reported here. cutaneous metastases are of diagnostic importance because they may be the first manifestation of an undiscovered internal malignan...

the yankee is an american national phenomenon. he had leapt into national stature when slipped outside of his local character. a myth was woven around him and a cult of the yankee developed by the permeation of the yankee characteristics in many different characters who played tricks or told stories and entertained their audiences. the present article is an attempt to observe the yankee myth, i...

endometriosis is defined as the presence of functioning endometrial tissue outside the uterine cavity. endometriosis can sometimes occur in a previous surgical scar. scar endometriosis is rare and difficult to diagnose. it mostly follows obstetrical and gynecological surgeries. this condition is often confused with other surgical conditions. we are reporting one case of scar endometriosis invol...

introduction: based on the invasive studies it has been shown that factors such as age, the progress of eye disorders, lens fibers compression and the biochemical changes of ocular matrix alter the physical characteristics and elastic properties of eye. in this study, a noninvasive method of estimating human eye elasticityis proposed and its relation with age and gender is evaluated using ultra...

The present study compared the performance of soldier pile and concrete bearing pad anchored wall facings. Using Abaqus finite element software, two case studies have been precisely represented for the facing designs and effects of the parameters of soil type, spacing of anchors and facings, surcharge and facing sizes were investigated. The analysis results indicate that the soldier pile method...

the combination of flexural frame and shear wall is one of the suitable systems to apply in reinforced concrete buildings. the deflections of flexural frame become limited due to the high stiffness of wall and the interaction of these systems. tall buildings even higher than fifty stories can be designed by using frame- wall systems. with respect to special behavior of flexural frame or shear w...

abdominal wall hernia is common but reliable scientific data about its work relatedness is very limited and inconsistent. in this paper, a less common type of abdominal wall hernia in a 30 year old male worker is presented with recurrence after first surgery when he returned to work. in contrast with almost all kinds of hernia, a lifelong limitation for heavy lifting was recommended. it seems t...

this study was designed reevaluate the outcome of soft wall reconstruction technique for cwd mastoidectomy and to test the validity of anteriorly–based musculoperiosteal flap attachment without oblitrating the mastoid cavity for increasing graft viability. two methods of reconstruction were used. soft wall reconstruction method as described previously by smith et al, were performed on 35 patien...

during past earthquakes, many instances of building damage as a result of earthquake surface fault rupture have been observed. the results of investigating a potential mitigation scheme are presented in this paper. such plan provides a wall in the soil with the aim of surface displacement localization in the narrow pre-determined location. this may reduce the risk of the future rupture downstre...
