BACKGROUND AND PURPOSE The Action Research arm test (ARAT) was constructed for assessing recovery of upper extremity function after cortical injury. The objective of the study was to verify the inter-rater reliability and validity of the ARAT in stroke patients. METHODS 50 stroke patients participated in the study. For the purpose of inter-rater study, the ARAT was administered by three exper...

this study attempts to investigate the origin of red pigments, time of reddening, and processes responsible for red colouring of the upper miocene age upper red formation, the most important clastic unit in central iran. mineralogical composition and textural properties of the studied sequences show that the upper red formation sequences were not red when deposited, although some parts of red p...

gastrointestinal stromal tumors (gist) are the most common mesenchy­mal tumors of the gastrointestinal tract. the biological pattern of these tumors ranges from benign-appearing small lesions to malignant sarcomas. only 3%-5% of gists are found in the duodenum. a duodenal gist is a rare source of upper gastrointestinal bleeding. a remarkable percentage of duodenal gists are localized in the thi...

The excellent preservation of the acritarchs, their great abundance, diversity and good stratigraphic control permit establishment of a detailed Middle and Late Cambrian acritarch biozonation. A total of 56 palynomorph species form the basis of 10 local acritarch assemblage zones. Assemblage zones I-II occur in the lower and middle parts of the Member C of the Mila Formation and suggest Early-m...

frasnian - famennian boundary in the kal-e-sardar section (east of tabas, central iran) is investigated on the basis of conodonts. distribution of thirty-three species and subspecies in the stratigraphic column enables us to recognize a barren interval and five biozones; upper rhenana, upper part of upper rhenana - linguiformis, lower to middle triangularis, upper triangularis, lower crepida. b...

The problem of attitude stabilization of a fighter aircraft is investigated in this paper. The practical aspects of a real physical system like existence of external disturbance with unknown upper bound and actuator saturation are considered in the process of controller design of this aircraft. In order to design a robust autopilot in the presence of the actuator saturation, the Composite Nonli...

Objective(s): The energy resolution of a cadmium-zinc-telluride (CZT) solid-state semiconductor detector is about 5%, and is superior to the resolution of the conventional Anger type detector which is 10%. Also, the window width of the high-energy part and of the low-energy part of a photo peak window can be changed separately. In this study, we used a semiconductor detector and examined the ef...

Complex facial injuries with soft tissue degloving and bony avulsion are very devastating to the patient. Partial degloving injuries are described but hemifacial degloving with zygoma avulsion are rare. The author presents a case of post-traumatic degloving of the left upper lip, nose, part of forehead, upper and lower eyelids and cheek with avulsion of the left zygoma. The management include...
