Analysis of flow

Predicting the macroscopic permeability of porous media is critical in various scientific and engineering applications. This study proposes a novel model that combines Random Forest (RF) and rime-ice (RIME) optimization algorithm, denoted RIME-RF-RIME, to predict permeability based on six key features covering fluid phase dimensions, geometric characteristics, surrounding phase permeability, and media porosity.

This research proposes strategic solutions for attracting Foreign Direct Investment (FDI) to develop eco-industrial parks in the Red River Delta region through 2030, with a vision for 2050. The author's proposed solutions are grounded in a comprehensive analysis of the current status and developmental trends of eco-industrial park models, forecasted impacts of international and domestic contexts on FDI flows, and the competitive advantages of the Red River Delta region in attracting FDI specifically for eco-industrial parks.

ESI greatly enhanced the ability to characterize protein and peptides by MS.
ESI requires the sample of interest to be in solution- flow in to the ionization source region.
To ionize the sample, high voltage is applied, result in the sample becoming positively or negatively charged; however, positive ionization is used primarily in the analysis proteins and peptides.
As it exits the spray tip, the solution produces submicrometer-sized droplets containing both solute and analyte ions. The sample is then desorbed of solute prior to entering the analyzer region....

I. Introduction An important aspect of nuclear reactor core analysis involves the determination of the optimal coolant flow distribution and pressure drop across the reactor core. On the one hand, higher coolant flow rates will lead to better heat transfer coefficients and higher Critical Heat Flux (CHF) limits. On the other hand, higher flows rates will also in large pressure drops across the reactor core, hence larger required pumping powers and larger dynamic loads on the core components.

The increasing use of Intelligent Transport System (ITS) can enable very close vehicle spacings which generally results in a net drag reduction for the resulting convoys. The majority of vehicle development has, to date, been for vehicles in isolation, thus the study of interaction effects is becoming increasingly important. The main objective of this research is to investigate the use of Computational Fluid Dynamics (CFD) for understanding convoy aerodynamics and to further the understanding of airflow interaction between vehicles via CFD.

This study aims to use CFD analysis of CT scan data from the nasal cavities of a range of older Asian males to investigate the impact of geometric variations between older nasal cavities on the airflow structures and airconditioning capacity of the nasal cavity. Air flow mechanisms, heat transfer rates and humidification efficacy are analysed in order to arrive at a more precise understanding of the role of nasal geometry in the presentation of respiratory ailments.

Trade and world economic integration are seen as the impetus for accelerating the well-beings of the domestic Vietnamese communities and international community in the region. However, an understanding of the link between trade and economic integration from the perspective of Vietnam is missing. Empirical studies on Vietnamese trade are in lack to address these determinants (see, Le, 1996; Nguyen, 2010). This thesis identifies the key factors that have driven the impressive growth of Vietnamese exports during the world economic integration process (1986-2010).

Penicillin acylase catalyses the hydrolysis and synthesis of semisyntheticb-lactam antibiotics via formation of a cova-lent acyl-enzyme intermediate. The kinetic and mechanistic aspects of these reactions were studied. Stopped-flow experiments with the penicillin and ampicillin analogues 2-nitro-5-phenylacetoxy-benzoic acid (NIPAOB) and D-2-nitro-5-[(phenylglycyl)amino]-benzoic acid (NIPGB) showed that the rate-limiting step in the conversion of penicillin G and ampicillin is the formation of the acyl-enzyme....

The roles of His181, His184 and Tyr186 in PETN reductase have been examined by mutagenesis, spectroscopic and stopped-flow kinetics, and by determination of crystallographic structures for the Y186F PETN reductase and reduced wild-type enzyme—progesterone complex. Residues His181 and His184 are important in the binding of coenzyme, steroids, nitro-aromatic ligands and the substrate 2-cyclohexen-1-one.

Purified recombinant proteins fromSynechocystisPCC6803 were used to show that the magnesium chelatase ChlH subunit stimulates magnesium protoporphyrin methyltransferase (ChlM) activity. Steady-state kinetics demonstrate that ChlH does not significantly alter theKmfor the tetrapyr-role substrate. However, quenched-flow analysis reveals that ChlH dramat-ically accelerates the formation and breakdown of an intermediate in the catalytic cycle of ChlM.

Inorder to clarify the role of cytochrome innitrate reductase we have performed spectrophotometric and stopped-flow kinetic studies of reduction and oxidation of the cytochrome hemes with analogues of physiological quinones, using menadione as an analogue of menaquinone and duro-quinone as an analogue of ubiquinone, and comparing the results with those obtained with dithionite. The spectropho-tometric studies indicate that reduction of the cytochrome hemes varies according to the analogue of quinoneused, and in no cases is it complete....

CD98 heavy chain (CD98hc), expressed at high levels in developing human trophoblasts, is an integral membrane protein with multiple N-linked gly-cosylation sites and known to be important for cell fusion, adhesion, and amino acid transport. Western blotting and flow cytometry were used to study the effect of brefeldin A, an inhibitor of protein translocation through the Golgi, on CD98hc in the human placental trophoblast cell line BeWo.

Heterogeneities in tumor blood flow are associated with cyclic changes in pO2 or cyclic hypoxia. A major difference from O2 diffusion-limited or chronic hypoxia is that the tumor vasculature itself may be directly influ-enced by the fluctuating hypoxic environment, and the reoxygenation phases complicate the usual hypoxia-induced phenotypic pattern.
