i read with interest dr. yazdani's reply about the article entitled “administration of magnesium sulfate to women with premature labor: the effect on bleeding time”. 1 in my review of hematology references, i could not find any reference for determining hemoglobin (hb) sooner than 24 hrs and dr. yazdani had not cited any reference either. however, about the influence of hb on homeostasis, there...

Dense phase pneumatic conveying is widely used to transport granular materials or powder due to its efficiencies gained on cost and abrasion and erosion. To date these systems have been designed and analyzed using average frictional representation for the conveyed plug. This study explores the effect of this friction force by measuring strains on the pipe wall when the plug is moving passed the...

Pulmonary arteriovenous malformations (PAVM) are rare vascular malformation, having direct communication between a pulmonary artery and pulmonary vein, bypassing intervening capillary bed. Traditionally, minimally invasive, endovascular Interventional treatment using coils has been the treatment of choice for PAVM. Our case report highlights emerging role of vascular plug in treating PAVM. Vasc...

Using equations obtained in a previous analysis, results are computed numerically which illustrate the effects of diffusion and viscosity on faecal excretion patterns of markers in ruminants. Results are first given for plug flow, a velocity gradient produced by viscosity, and diffusion, each mechanism operating alone. Plug flow gives a period during which no marker appears in the faeces, then ...

A microfluidic device and operation to handle liquid plugs for biochemical analyses were developed for efficient handling of plugs of many solutions. A major part of the device was a T-junction consisting of a main flow channel and a handling flow channel. Unit operations including attachment of plugs, division of a plug, sorting of plugs, and formation of plugs of various lengths enabled contr...

This paper presents the Eclipse plug-ins for the Task Flow model in the Discovery Method. These plug-ins provide an IDE for the Task Algebra compiler and the model-checking tools. The Task Algebra is the formal representation for the Task Model and it is based on simple and compound tasks. The model-checking techniques were developed to validate Task Models represented in the algebra.

The Event Refinement Structures (ERS) approach provides a graphical extension of the Event-B formal method to represent event decomposition and control-flow explicitly. In this paper we present an improved version of the ERS plug-in, which provides a graphical environment for the ERS approach within the Event-B tool, Rodin. The improved ERS plug-in is based on the available frameworks that are ...

Despite its wide application across arid land types, furrow irrigation is often associated with numerous environmental problems related to deep percolation, runoff, and soil erosion. In this study, a straightforward approach was proposed achieve higher uniformity reduce Here, the impacts that moveable “plug” has on behavior of water in were simulated using FLOW-3D HYDRUS-2D, where three plug he...

When you reach with your straw for the final drops of a milkshake, the liquid forms a train of plugs that flow slowly initially because of the high viscosity. They then suddenly rupture and are replaced with a rapid airflow with the characteristic slurping sound. Trains of liquid plugs also are observed in complex geometries, such as porous media during petroleum extraction, in microfluidic two...
