Annals of Neurology, EarlyView.Objective The extent of neuronal loss in Parkinson's disease (PD) and the pathogenic processes underlying neuronal dysfunction and loss remain poorly understood. Here, we analyzed the expression of key molecules representing different cell death signaling pathways and their association with Lewy pathology, dopaminergic (DA) neuron loss and stage of PD ...

Experimental Investigation of Microbubble Evolution in the Liquivac Multiphase Flow Pump
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This paper aims to experimentally investigate the mechanisms of microbubble characteristics evolution within an axial pump. The findings will aid in assessing the pump performance by identifying the range of bubble sizes and comparing them with the threshold size (< 300 μm). This study also provides evidence supporting the use of such pumps as

Complex singularities and PDEs
, 2015 In this paper we give a review on the computational methods used to characterize the complex singularities developed by some relevant PDEs. We begin by reviewing the singularity tracking method based on the analysis of the Fourier spectrum.

Exergy and Economic Analysis of Hybrid Mechanical Vapor Compression and Membrane Distillation
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Hybridization of two or more desalination processes has been identified as an attractive option for improved energy efficiency and recovery rate. To appropriately assess the performance enhancement of hybrid desalination systems, an integrated approach for energy, exergy, economic, and environmental investigations should be adopted. This study

Time-asymptotic solutions of the Navier-Stokes equation for free shear flows using an alternating-direction implicit method [PDF]
An uncoupled time asymptotic alternating direction implicit method for solving the Navier-Stokes equations was tested on two laminar parallel mixing flows.

Numerical and Experimental Study of Mixing Characteristics in a Spiral Micromixer
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Significant enhancement of mixing performance can be achieved by Dean vortices in spiral channels. In order to deeply explore the mixing mechanisms and variation laws in spiral micromixers, this work designed a spiral micromixer and adopted a combined method of experiments and numerical simulations to analyze the mixing performance and ...

From Bench to Bulk: Investigating Kinetics, Recyclability, and Scale‐Up of ZIF‐67
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Zeolitic imidazolate framework‐67 (ZIF‐67), a subclass of metal–organic frameworks (MOFs), has garnered considerable attention due to its high surface area, open crystal structure, tunable porosity, and potential applications in gas separation, catalysis, and carbon capture.

An improved viscid/inviscid interaction procedure for transonic flow over airfoils [PDF]
A new interacting boundary layer approach for computing the viscous transonic flow over airfoils is described. The theory includes a complete treatment of viscous interaction effects induced by the wake and accounts for normal pressure gradient effects ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...
