Abstract:

Liver is the primary source of numerous proteins that are critical for normal function of the blood coagulation cascade. Because of this, diseases of the liver, particularly when affiliated with severe complications like cirrhosis, are associated with abnormalities of blood clotting. Although conventional interpretation has inferred cirrhosis as a disorder of uniform bleeding risk, it is now increasingly appreciated as a disease wherein the coagulation cascade is precariously rebalanced. Moreover, prothrombotic risk factors are also associated with a more rapid progression of fibrosis in human

Findings – The numerical results show that the interaction of the two jets and turbulence eddy structures rolling-up, paring and shedding in flow sharply affects particles number concentration. Particle diameter grows quickly at the interfaces of jets. Coagulation shows more obvious effect at initial stage than that

Corncob cellulose from residue of saccharified agricultural waste corncob was used as a new resource of cellulose to dissolve in 1-allyl-3-methylimidazolium chloride (AmimCl) and then to regenerate in three different coagulation baths: water, 60 wt% AmimCl aqueous solution, and anhydrous ethanol. The effects of the different coagulation baths on the properties of corncob cellulose aerogels and regenerated films were studied. The results showed that the aerogels had porous network structures, and the regenerated films were relatively transparent with high strengths and good thermal stabilities.

In our early work in developing activated clotting time (ACT) assays, it became apparent that changes occurred in coagulation times as a whole blood sample aged (0-6 h).

These changes in whole blood clotting times during storage were eventually traced to the platelets. Several years of work demonstrated that this change was due to the removal of the blood from the vascular lining. This recalled a mechanism that was originally put forth in the 1970s with the disc

Near-source biomass burning aerosol coagulation occurs at spatial scales much smaller than the grid boxes of global and many regional models. To date, these models have ignored sub-grid coagulation and instantly mixed fresh biomass burning emissions into coarse grid boxes.

Abstract Abstract 1415 Poster Board I-438 Introduction: Critical laboratory values (CVs) are those that indicate the patient is in danger of death unless corrective action is initiated immediately. CVs are an important feature of laboratory practice parameters, standards of regulatory agencies (including the Joint Commission's National Patient Safety Goals), and national and institutional quality improvement studies. However, there has been no research into CVs in coagulation laboratories. Our objectives were to determine: 1) The current policies on CVs in specialized coagulation laboratories

Abstract:

The paper presents the results of the study of feasibility of obtaining high-quality foamed thermal insulation materials based on a silicate matrix with addition of dolomite. It has been found out that the preliminary activation of a suspension based on a silica-containing component at a temperature of 90°C for 5-7 minutes allows accelerating the coagulation of silica fume and the synthesis of sodium silicates. Optimal foaming conditions for the charge frothing are 650-700°C for 25 minutes. There have been obtained foam silicates with a relatively uniform finely porous structure and stable phy

Abstract:

Purpose – The original v2-based sectional method assumes that the selected property quantity of particles is uniformly distributed in each section, which makes particle size distribution (PSD) fluctuate dramatically in the entire size range. The number concentration in each section as well as the zeroth moment of PSD also cannot be correctly predicted in case there are not enough sections used in calculation. In order to provide a more appropriate representation of PSD, different approximate models are used to close the conservation equations. The paper aims to discuss these issues. Design/met

Abstract:

The article deals with the problem of thermomechanical processing conditions influence on the properties of dry whey protein ingredient solutions: whey protein concentrates and isolates. The initial stage of obtaining fat property mimics is heat treatment of protein solutions to the temperature exceeding the denaturation threshold (65-75 °C). The next mechanical impact on the aggregates obtained leads to the formation of the particles similar to the fat globules. Protein mass fraction has a significant influence on the denaturation process. When its value becomes larger, the number of collisio

Abstract:

Thermal ablation is a minimally or noninvasive cancer therapy technique that involves fewer complications, shorter hospital stays, and fewer costs. In this paper, a thermal-ablation bioheat model for cancer treatment is numerically investigated, using a porous media-based model. The main objective is to evaluate the effects of a variable blood volume fraction in the tumoral tissue (i.e., the porosity), in order to develop a more realistic model. A modified local thermal nonequilibrium model (LTNE) is implemented including the water content vaporization in the two phases separately and introduc

The efficiency of magnetic seed coagulation (MSC) with pH adjustment by NaOH and Ca(OH)2 as a pretreatment for high-strength natural rubber industrial wastewater (NRIWW) was compared in this study. The high content of suspended solids (SSs) and other inhibitory substances of NRIWW is a primary issue which affects its subsequent secondary and tertiary treatment processes. The MSC process with polyaluminum chloride (PAC), anionic polymer (polyacrylamide—PAM)), and magnetic seeds (MS) (ferric oxide (Fe3O4)) was proven to be a cost-effective pretreatment of NRIWW, and Ca(OH)2 showed improved pretr

Volumetric diameters Dv and specific surface area SpS of sludge particles formed during chemical coagulation and electrocoagulation of sewage were determined. The obtained aggregate-flocs differed substantially in both Dv and SpS values. The differences in Dv and SpS values of the analyzed particles were interpreted based on theoretical models for expanding aggregates. The most uniform particles were formed under exposure to: (a) optimal and maximal doses of PIX, (b) optimal doses of PAX, (c) maximal doses of the Al electro-coagulant. The lowest PIX dose produced the least uniform particles. S

The non-uniform distribution of Nb ribbons throughout the composite cross sections was revealed, at higher strain their structure being more dispersed. In both wires the Cu/Nb interfaces are partly coherent, and the Nb lattice is more distorted at interfaces than in the bulk. The behavior at heating was studied in the temperature range of 300-800оС.

Abstract:

SummaryThe progression of neoplasms is frequently associated with thromboembolic complications. Coagulation proteins, particularly tissue factor (TF), have been shown to play a role in tumor growth and metastatic dissemination. TFPI is the principal inhibitor of TF-dependent pathway of blood coagulation, but previous studies failed to detect antigenic TFPI in cancer tissue. Recently, a second inhibitor of tissue factor dependent pathway, TFPI-2 (also known as placental protein 5 [PP5] or matrix-associated serine protease inhibitor [MSPI]), has been described.

In order to clarify the effect of particle coagulation on the heat transfer properties, the governing equations of nanofluid together with the equation for nanoparticles in the SiO2/water nanofluid flowing through a turbulent tube are solved numerically in the range of Reynolds number 3000 ≤ Re ≤ 16,000 and particle volume fraction 0.005 ≤ φ ≤ 0.04. Some results are validated by comparing with the experimental results. The effect of particle convection, diffusion, and coagulation on the pressure drop ∆P, particle distribution, and heat transfer of nanofluid are analyzed. The main innovation is

The study is devoted to the study of the effect of coagulation of dispersed phase droplets on aerosol oscillations in an acoustic resonator. The mathematical model of aerosol dynamics implements a continuous mathematical model of the dynamics of a multiphase medium, taking into account the velocity and thermal inhomogeneity of the mixture components. To describe the dynamics of the carrier medium, a two-dimensional unsteady system of Navier – Stokes equations for a compressible gas is used, written taking into account the interphase force interaction and interphase heat transfer.
