Inorganic micro®ltration membranes with a pore size down to 0.1 mm have been made using laser interference lithography and silicon micro machining technology. The membranes have an extremely small ̄ow resistance due to a thickness smaller than the pore size, a high porosity and a very narrow pore size distribution. They are relatively insensible to fouling, because they have a smooth surface, s...

A variety of in ltration techniques can be used to fabricate solid materials, particularly composites. In general these processes can be described with at least one time dependent partial di erential equation describing the evolution of the solid phase, coupled to one or more partial di erential equations describing mass transport through a porous structure. This paper presents a detailed mathe...

The relationship between the pore liquid pressure (pL) and the cake compressive stress (ps) is required in analyzing cake ltration. This relationship (for the one-dimensional case) is commonly assumed to be dpL+dps =0 although similar but di#erent ones may also be advanced from the multiphase 9ow theory. The e#ect of these di#erent expressions is studied by examining the correspondence between ...

experiment on the protective role of simvastatin against ventilator-induced lung injury (VILI). Th eir results are in line with those of a relevant study published recently by our research team; we also showed that pretreatment with statins (specifi cally atorvastatin) attenuates VILI [2]. By synthesizing the fi ndings of the above contributions [1,2], one could make several points. First, give...

(Received) We study the Weyl closure Cl(L) = K(x)h@iL \ D for an operator L of the rst Weyl algebra D = Khx;@i. We give an algorithm to compute Cl(L) and we describe its initial ideal under the order ltration. Our main application is an algorithm for constructing a Jordan-HH older series for a holonomic D-module and a formula for its length. Using the closure, we also reproduce a result of Strr...

T cell migration was analyzed intravitally in the last few years using noninvasive two-photon microsco...

genic leucocytes from donor blood are responsible for serious untoward effects in some transfused patients such as alloimmunization, febrile reactions, platelet refractoriness, transfusion associated acute lung injury, immunosuppression as well as transmission or reactivation of viruses such as CMV, HTLV or EBV. Leucocytes are also known to accelerate the rate of storage lesion. The optimal met...

Estimation of soil hydraulic and solute transport parameters is important to provide input parameters for numerical models simulating transient water ̄ow and solute transport in the vadose zone. The Levenberg±Marquardt optimization algorithm in combination with the HYDRUS-1D numerical code was used to inversely estimate unsaturated soil-hydraulic and solute transport parameters from transient m...
