On high-speed networks, the round trip delay from source to intermediate node and back is relatively large compared with packet transmission times; thus, the window-based method of flow control does not react quickly enough to prevent congestion and large delay. An alternative method is to employ a rate-based flow control scheme, in which each node is assigned a maximum rate and an average rate...

abstract background: inadequate dialysis is one of the main causes of mortality of the patients undergoing hemodialysis. the methods that lead to improvement of dialysis adequacy in these patients are of great importance due to them causing an improvement of quality of life. as numerous factors can play a role in improvement of dialysis adequacy, the present study aimed to investigate the level...

objectives: periodontal pathogens need acidic environments to proliferate in periodontium, and their growth is affected by the salivary flow rate and ph of the mouth. alterations in flow and acidity of saliva have an important effect on oral diseases such as periodontitis. this study was designed to compare salivary ph and flow rate before and after using green tea, black tea and coffee in pati...

background: measuring peak expiratory flow rate has been suggested as an important tool in asthma management by all international guidelines.   objective: studies on various populations have shown considerable variations in normal values of peak expiratory flow rate. since reference standards for iranian children are not available, the present study was performed to establish these standards.  ...

objective: diabetes mellitus is one of the most common metabolic disorders which have several oral complications such as hypofunction of salivary glands. the aim of present study was to compare the unstimulated whole saliva (uws) flow rate in diabetic type ii patients and healthy peoples who admitted in yazd diabetic center. materials and methods: in this analytic-observational study, 78 patien...
