the renewable energy resources such as wind power have recently attracted more researchers’ attention. it is mainly due to the aggressive energy consumption, high pollution and cost of fossil fuels. in this era, the future fluctuations of these time series should be predicted to increase the reliability of the power network. in this paper, the dynamic characteristics and short-term predictabili...

the proposal lateral load pattern for pushover analysis is given in two forms for symmetric concrete buildings: 1-(x/h)0.5 for low-rise and mid-rise buildings, 2- sin(πx/h) for high-rise buildings. these two forms give more realistic results as compared to conventional load patterns such as triangular and uniform load patterns. the assumed buildings of 4, 8, 12, 16, 20 and 30 story concrete bui...

Carcinosarcoma is a rare tumor consisting of epithelial and mesenchymal components, both of which are histologically malignant. It usually runs an aggressive clinical course, with higher metastatic potential than other kinds of carcinomas or sarcomas.Here, we present an extremely uncommon case of carcinosarcoma occurred in the lesser omental bursa in a 65-year-old Chinese man. Metastasis was ob...

THE Osler Club was founded to commemorate the name of one of the greatest and best-known physicians of all time, and it seemed fitting that at the Society's first meeting in Dublin the opening paper should try to pay tribute to some other physicians who, given the time, place and opportunity might have become just as well known, but were fated to work in relative obscurity, 'great' only in the ...

A 25-year-old man came to the emergency department complaining of continuous right para-umbilical pain radiating to the epigastric midline since the previous night. Pain was associated with tenderness. He had no fever and the rest of the physical examination was normal. Laboratory studies showed a normal white blood cell count and C-reactive protein level was 11 mg/L (normal < 10 mg/L). Pain wa...

Drought is a major environmental disaster in many parts of the world. Knowledge about the timing, severity and extentof drought can aid planning and decision-making. Drought indices derived from in-situ meteorological data have coarsespatial and temporal resolutions, thus, obtaining a real-time drought condition over a large area is difficult. This studyused advanced very high resolution radiom...

Several authors have attempted to classify metatarsalgia. Helal classified metatarsalgia into primary, secondary, and unrelated to weight distribution. Primary metatarsalgia is defined as pain across the area of the metatarsophalangeal joints associated with plantar keratoses. It may be a result of functional problems such as wearing a high-heeled shoe or structural problems associated with, fo...

Clinical case: A 46 year-old patient, with no significant past medical history or family medical history, complaining of mild epigastric discomfort and weight loss during the past year was examined by abdominal ultrasound. During the US examination a 11/9.5/6.5cm mass was identified anterior to the body and tail of the pancreas, and posterior to the stomach, in the area of the lesser sac (fig. ...
