The effect of the degree of polymer branching on retention and drainage performance of flocculated kraft pulp fiber suspensions containing precipitated calcium carbonate (PCC) was investigated and has been correlated with flocs properties obtained by light diffraction scattering (LDS). The results show that polymers of medium charge density are more adequate to be used as retention aids since l...

Combined with the GPRS (General Packet Radio Service) technology, Geographic Information Systems (GIS) extends its abilities from static to dynamic working environment for urban drainage network. In this paper, a framework of Web-GIS for the urban drainage network management system is presented. This three-layer system framework is based on the J2EE technologies. The principles of data structur...

BACKGROUND Closed suction drains are widely used in breast reconstruction, and the drains are removed based on a volume criterion. However, to the best of our knowledge, there has been no study analyzing predictive factors for drainage volume after breast reconstruction. METHODS Data of daily drainage in cases with expander-based breast reconstruction between February 2013 and March 2015 (131...

Although no proven evidence exists for the use of drainage in primary total hip arthroplasty, such drainage is routinely used. This prospective, randomized study comprised 80 patients who underwent a non-cemented total hip arthroplasty using a minimally invasive anterolateral approach. Patients were divided into 2 groups of 40: group 1 underwent drainage treatment and group 2 underwent no drain...

Nine cases of delayed mediastinal tamponade occurring between the 6th and 20th days after operation are described. AM patients were on anticoagulant therapy at the time tamponade occurred. Tube drainage of the medlastinum and wide drainage of the medisstinum into the pleural space did not prevent this complication. Eight of the nine cases were managed successfuUy by medi8stinal drainage through...

Abstmct--We consider the convergence properties of certain algorithms arising in storhastie, discrete-time, adaptive estimation problems and operating in random environments of engineering d@hnce. We demonstrate that the algorithms operating mder ideal conditions are d e s d i l e by homogeneous time-varying linear difference equations with dependent random coefficients, while in praclical use,...

This is the ®rst of two papers that elaborate an integrated drainage network analysis system (IDNAS) for agricultural drainage management. In this paper, the system components, functions and implementation are presented. The IDNAS comprises an agricultural drainage network module, an evapotranspiration (ET) module and an event-based spatio-temporal module. The network module is designed to mode...

introduction: post cardiac surgery hemorrhagic syndromes, potentialized by implementing   cardiopulmonary bypass, leads to increased hazards of blood products transfusion and          pertains serious impacts on immediate patients outcome. the objective of this clinical trial was to investigate the efficiency of exogenous fibrinogen to control hemorrhagic syndromes following cardiac surgery in ...

A 63-year-old nonsmoker with right malignant pleural effusion derived symptomatic benefit following drainage of his effusion. Following insertion of indwelling pleural catheter (IPC), 1.3 L of blood-stained fluid was drained into underwater sealed bottle (Atrium®), but the IPC dislodged 26 h after continuous connection. We believe that the weight of the drainage bottle (including the un-emptied...

The treatment of chronic pancreatic pleural effusions and pancreatic pseudocysts generally starts with a conservative approach including bowel rest, drainage of the pleural effusion by repeated thoracentesis or a chest tube, and total parenteral nutrition (TPN) for a period of time determined by the clinical course. Other treatment modalities including percutaneous drainage, endoscopic retrogra...
