This study aimed to determine the relation between the regression slope relating minute ventilation to carbon dioxide output (VE/VCO2 slope) and maximum phonation time (MPT), and the MPT required to attain a threshold value for VE/VCO2 slope of ≤ 34 in chronic heart failure (CHF) patients. This cross-sectional study enrolled 115 CHF patients (mean age, 54.5 years; men, 84.9%). VE/VCO2 slope was...
in this study the land surface in western half of hyper-arid lut desert, in south east of iran, which is covered by yardangs, a worldwide typical landform for aeolian erosion, were classified by self organizing maps (som) method. in the first step by using digital elevation model with 10 m resolution and matlab software, 22 morphometric parameters were calculated based on derivative of the surf...
Methods for identifying the size, or scale, of hillslopes and the extent of channel networks from digital elevation models (DEMs) are examined critically. We show that a constant critical support area, the method most commonly used at present for channel network extraction from DEMs, is more appropriate for depicting the hillslope/valley transition than for identifying channel heads. Analysis o...
The periodontal-restorative team is uniquely positioned to provide the esthetic procedures that today's sophisticated patient population has come to expect. Not only is health and function of great desire but also esthetics is in demand. Armed with periodontal-plastic procedures and technically advanced restorative materials, the periodontal-restorative team can provide these patient needs. The...
Three patients developed symptoms suggestive of acute schizophrenia. In each case there were no abnormal neurological findings on admission to hospital. Within a few days clinical evidence of encephalitis became apparent, and appropriate treatment was given. Only one patient made a full recovery.
asri@interchange Summary Periprosthetic fractures are increasing in number and complexity. Appropriate precautions should be taken to prevent these fractures. A systematic approach is needed in the form of detailed assessment of the fracture, stability of the implant and the available bone stock for planning an appropriate treatment. The treatment options described in this article can be used a...
Traditional views on facial aging and associated therapies focused on soft tissue descent and skin texture changes. Recently, revolumization for age-related lipoatrophy has become increasingly popular. Researchers are now reporting objective studies examining processes of structural and volumetric changes with age in increasing frequency as well. To better understand and treat facial aging, the...
Introduction: Appropriate office workstation design and adjusted keyboard slope could prevent upper extremity musculoskeletal disorders caused by CTDs. The purpose of this study was to compare wrist and finger motion angles during typing in different workstations with different keyboard slopes. Methods: In this experimental study, 10 female typists of university workers were chosen randomly....
Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...
