The research in the fields of irrigation and drainage network in the province Hamidieh to evaluate the performance of drainage was done in the land. For this purpose, three drainage server farm at intervals of 50, 70 and 80 meters in the area was selected. Blank observation on three drain pipes at intervals of 0.3,0.8,1.5,2.5 and 15 meters of lateral drains in the middle of the line in four row...

OBJECTIVES To evaluate the effectiveness of videothoracoscopic surgery in the treatment of complicated parapneumonic pleural effusion and to determine whether there is a difference in the videothoracoscopic surgery outcome before or after the chest tube drainage. METHODS The medical records of 79 children (mean age 35 months) undergoing videothoracoscopic surgery from January 2000 to December...

BACKGROUND The purpose of this study was to determine whether repeated clamping of a suction drainage system will result in less external blood loss, blood transfusion and no increase in complications compared to a routine continuous suction drainage system. This was a randomized prospective study on patients undergoing total knee arthroplasty. METHODS Group A patients' drains were left clamp...

this report summarizes the results of 64 percutaneous catheter drainage of abdominal abscesses and fluid collections in 56 patients. aspiration and drainage was guided with computed tomography in 34 patients and with ultrasound in 30 patients. success rate was 90%. infected collections were successfully drained in 94% and noninfected collections in 72% . partial success was achieved in two pati...

Background:Robotic video-assisted surgery (RVATS) has been reported to be equally effective to video-assisted surgery (VATS) in lung resection (pneumonectomy, lobectomy, and segmentectomy). Operation time, mortality, drainage duration, and length of hospitalization of patients undergoing either RVATS or VATS are compared in this meta-analysis. Methods: A systematic research for articles meeting...

Background: Primary spontaneous pneumothorax occurs in young, healthy populations, usually males, in the absence of lung disease. Secondary spontaneous pneumothorax occurs in older adults who have underlying lung disease such as COPD, emphysema, or a malignant growth. The estimated incidence of spontaneous pneumothorax is 7.4 to 18 per 100,000 for males and 1.2 to 6 per 100,000 in females. Trad...

foaming conditions of the red beet (beta vulgaris l) puree were optimized using response surface methodology (rsm) with respect to arabic gum concentrations (0.01 – 0.4% w/w), red beet puree (40 _ 60% w/w),egg white concentration( 5 _ 15% w/w) and whipping time (3 – 9 min) for minimum foam density and foam drainage volume as response variables. foams were prepared from various pulp concentratio...

A modified model has been analytically developed to describe the induction time of an elliptic air bubble in contact with an elliptic hydrophobic oil droplet. The role of hydrophobicity was revealed in the slippage of liquid over the surfaces of bubble and droplet. In this condition, the analytical relationships for pressure distribution and consequently hydrodynamic resistance force through th...
