Measurement of urinary flow rate
Urology, 1983The various methods for measuring urinary flow rate from the first attempt by Rehfisch in 1897 to current techniques are described. The benefits or deficiencies of each method are considered, and it is concluded that while some of the more technically sophisticated pieces of equipment are necessary for the accurate determination of flow rates in the ...

Flow-Rate Estimates for Rectilinear Pipe Flow
Journal of Applied Mechanics, 1974A means is established for finding upper and lower bounds on the flow rate of viscous incompressible fluids in straight pipes. Bounds are derived for a class of flow regions having as cross section a strip or annulus, and used to deduce an approximation appropriate to such sections when they are thin. Explicit error-bound results are included.

The Indian Journal of Pediatrics, 1976
From the Force Vital Capacity tracing obtained in 174 healthy school boys between 7 and 16 years of age, the flow over the initial 500 ml. (M.E.F.R. 1–700), middle half (M.M.F.) and third arter (E.F.R. 50–75) were calculated. data were statistically analysed and results compared with Western data.

Maximum Flow Rates for Microcatheters
Radiology, 1977Microcatheters are defined as those with outer diameters of 4 French gauge or less. Authors tested five sizes of catheters from 2 to 4 French, inclusive to determine the bursting and maximum safe flow rates with automatic injectors. This communication describes the maximum flow rates for various sizes and lenghts, as well as the feasibility of ...

Interpretation of Urinary Flow Rates
Urologic Clinics of North America, 1990The uroflow examination is the most accurate, physiologic, and noninvasive method of assessing bladder outflow obstruction. The examiner must be aware of the errors that may arise from problems inherent in the uroflowmeter, in the patient (such as psychological inhibition), or in bladder physiology (such as the influence of intravesical volume ...

ACM SIGCOMM Computer Communication Review, 2007
Resource allocation and accountability keep reappearing on every list of requirements for the Internet architecture. The reason we never resolve these issues is a broken idea of what the problem is. The applied research and standards communities are using completely unrealistic and impractical fairness criteria.

QoS control mechanism based on flow rate to improve quality of short flows and low-rate flows
2010 IEEE Network Operations and Management Symposium - NOMS 2010, 2010The dominant IP traffic is moving from Web to peer-to-peer (P2P) these days. As a result, elephant flows consume bandwidth and unfairness in resources allocation occurs. The main packet-scheduling mechanism currently employed is first-in first-out (FIFO) where the available bandwidth of short flows is limited by elephant flows.

Unsteady magnetohydrodynamic flow with variable flow rate
1985The problem of unsteady magnetohydrodynamic channel flow due to an arbitrarily time-varying flow rate has been solved for a fluid of anisotropic electrical conductivity. The velocity and wall shear stress have been calculated for a given flow rate. It is found that the effect of exponential flow rate is to flatten the velocity profiles and to reduce ...

Microvascular Function at Reduced Flow Rates
Journal of Tissue Viability, 1976Microvascular reactions to reduced flow in human skin as observed by vital microscopy are described. The behaviour of the cellular components of blood is analysed. Recirculation with only minor disturbances in the microcirculation was found even after complete occlusion for three hours.
