Flexibility is a concept associated with variable needs of human beings.Today transformable structures are used to meet human changeable demands with different purposes and functions such as facades, roofs, sunshades, etc.A Flexible structure must be able to change physically and adapt to predetermined conditions.To provide flexibility and adaptability,transformable systems are required to poss...

In this case report, we described a 74-year-old female patient with major complaint of respiratory problemsdyspnea after meal. Chest X-ray of the patient revealed a  gianttype IV hiatal hernia. Preoperative evaluations of the patient included esophagoscopy, esophageal manometry, barium swallow, and CT-scan. Repair of the hernia was performed using a dual mesh on the diaphragm and partial anteri...

A 4-month-old, intact male domestic short-hair cat was presented to Veterinary Hospital with an acuteonset of regurgitation and respiratory distress. Thoracic and abdominal radiographs identified a massconsisted of a heterogeneous mixture of soft tissue and gas densities between heart and craniodorsal part of the diaphragm that was shifted to the left. The stomach could not be seen clearly. Rad...

Let $X$ be a sufficiently nice scheme. We survey some recent progress on dualizing complexes. It turns out that a complex in $kinj X$ is dualizing if and only if tensor product with it induces an equivalence of categories from Murfet's new category $kmpr X$ to the category $kinj X$. In these terms, it becomes interesting to wonder how to glue such equivalences.

making a conservative bridge using a natural tooth pontic with mobile teeth is complicated, time-consuming and sometimes impossible with the current techniques and materials. the aim of this paper is` to describe a new method using special rigid tray technique (srtt) to deal with such difficult clinical cases.

ground differential movements due to faulting have been observed to cause damage to engineered structures and facilities. although surface fault rupture is not a new problem, there are only a few building codes in the world containing some type of provisions for reducing the risks. fault setbacks or avoidance of construction in the proximity to seismically active faults, are usually supposed as...
