BACKGROUND Intracranial lesions of the pituitary gland are common pituitary adenomas, accounting for 6-10% of all symptomatic intracranial tumors. In this retrospective study, the clinicopathologic features and survival rate of pituitary adenomas were evaluated. METHODS The present retrospective study was conducted on 83 patients with pituitary adenomas, referring to radiation oncology depart...

Seawalls are sheltering structures used for protecting the coastal regions against wave induced forces. Because of random nature of the wave behavior, application of physical models for the study of wave-structure interaction can be quite efficient. In the present research, physical models of thin flexible walls were constructed and tested in a wave flume subject to generated random waves. The ...

For this project, we investigate different methods of adding locationbased security to a WLAN network. A literature review is done to confirm the current state-of-the-art on the subject, and we scrutinize the available methods based on practicality, security, and simplicity. We then further delve into a few specific methods with good properties based on the prior review, to confirm if these are...

Environmental stress, especially drought stress, can play an important role in the reduction of the plant growth stage, specifically duringgermination in arid and semi arid regions in Iran.. In order to study the effects of drought stress on germination indices in wheat cultivars, an experiment was conducted in factorial form, using a completely randomized design of four replications. In this e...

BACKGROUND Primary bone lymphoma (PBL) is a rare disease and distinct clinicopathological entity. The optimal treatment strategy is still unclear. Because of rarity of PBL, we report our institute experience in PBL clinicopathological feature and treatment results. METHODS 28 patients diagnosed with PBL were referred to Omid Hospital, cancer research center (CRC), between March 2001 and Febru...

In image-guided surgical tasks, the precision and timing of hand movements depend on the effectiveness of visual cues relative to specific target areas in the surgeon’s peri-personal space. Two-dimensional (2D) image views of real-world movements are known to negatively affect both constrained (with tool) and unconstrained (no tool) hand movements compared with direct action viewing. Task condi...

the new cereal, primary tritipyrum is a synthetic amphiploid derived from crossing between durum wheat varieties (triticum durum, 2n=4x=28, aabb) and wild coach grass species (thinopyrum bessarabicum, 2n=2x=14, ebeb). in this study the genotype × environment interaction effect containing change in rank and value for grain yield of seventeen genotypes including eight primary and combined primary...
