Background and Aim: Chest tube has been used as a close drainage system for evacuation of pleural cavity after thoracic surgery and in traumatic patients.Today, the chest bottles are made from hard and fragile material that may be broken easily. Also chest bottle needs sterile saline solution for proper functioning. This causes heaviness with pressure effect on the chest wall, resulting in...
Recent studies have indicated that plantar-based vibration may be an effective approach for the prevention and treatment of osteoporosis. We addressed the hypothesis of whether the plantar vibration operated by way of the skeletal muscle pump, resulting in enhanced blood and fluid flow to the lower body. We combined plantar stimulation with upright tilt table testing in 18 women aged 46-63 yr. ...
nesar anticline is located in west of country and in north of kermanshah province. pattern of drainage network at each district is under the effect of various factors which has intensive anomaly in nesar anticline in spite of its low area and this in turn reflects different lithology, tectonic effects and slope changes in anticline. the goal of this research is the recognition of influential fa...
Phoebe sheareri is an excellent roadside tree with a wide distribution range and high ornamental value. Excessive moisture can affect the external morphology, microstructure, ultrastructure of leaf. Little known at present regarding leaf structure P. under waterlogging stress. In this paper, morphology leaves, microstructure epidermis, mesophyll cells seedlings stress drainage were dynamically ...
Nowadays the use of remote sensing and Geographic Information System (GIS) is one of the most powerful cost effective tools to identify and discover the available groundwater resources. In this paper, Lithological Units, Lineaments, Slope, Topography, Drainage density, Vegetation and Isohyets lines have been achieved by stations and through remote sensing and GIS techniques. All layers of diffe...
The aim of this study is to prepare the groundwater spring potential map using Weight of Evidence, logistic regression, and frequency ratio methods and comparing their efficiency in Chehlgazi watershed, province of Kurdistan. At first, 17 effective factors in springs occurrence including geology, distance to fault, fault density, elevation, relative permeability of lithological units, slope ste...
Today, supplying water to meet the sustainable development goals is one of the most important concerns and challenges in most countries. Therefore, identification of the areas with groundwater potential is an important tool for conservation, management and exploitation of water resources. The purpose of this research was to prepare the potential groundwater map in Nahavand, Hamedan Province, us...
One of the slopping processes which creates tremendous damage in many locations of Iran and the world is landslide phenomenon. Creating a landslide susceptibility map provides the possibility to recognize susceptible areas and to verify them in the environmental programs. The purpose of this research is to map the susceptibility of landslide in Taleghan watershed by establishing informational l...
BACKGROUND The purpose of this research is to compare the clinical results of different drainage methods in total knee arthroplasty (TKA). METHODS This retrospective comparative study included 55 patients who accepted primary unilateral TKA between October 2010 and November 2012. The patients were classified according to the drainage method used: 25 patients in the autotransfusion drainage gr...
