Numerical simulations are performed to study the combustion processes of n-heptane and methanol/air/EGR under high-temperature and high-pressure conditions relevant to a dual-fuel compression-ignition engine. Detailed chemical kinetic mechanism and transport properties are considered in the simulation. The simulations are carried out by performing three-dimensional (3D) direct numerical simulation

High-profile studies have provided conflicting results regarding the involvement of the Omi/HtrA2 gene in Parkinson's disease (PD) susceptibility. Therefore, we performed a large-scale analysis of the association of common Omi/HtrA2 variants in the Genetic Epidemiology of Parkinson's disease (GEO-PD) consortium. GEO-PD sites provided clinical and genetic data including affection status, gender, et

Early genome-wide association (GWA) studies on Parkinson's disease (PD) have not been able to yield conclusive, replicable signals of association, perhaps due to limited sample size. We aimed to investigate whether association signals derived from the meta-analysis of the first two GWA investigations might be replicable in different populations. We examined six single-nucleotide polymorphisms (SNP

OBJECTIVE: Eleven genetic loci have reached genome-wide significance in a recent meta-analysis of genome-wide association studies in Parkinson disease (PD) based on populations of Caucasian descent. The extent to which these genetic effects are consistent across different populations is unknown.METHODS: Investigators from the Genetic Epidemiology of Parkinson's Disease Consortium were invited to p

Joubert syndrome and related disorders (JSRD) are clinically and genetically heterogeneous ciliopathies sharing a peculiar midbrain-hindbrain malformation known as the 'molar tooth sign'. To date, 19 causative genes have been identified, all coding for proteins of the primary cilium. There is clinical and genetic overlap with other ciliopathies, in particular with Meckel syndrome (MKS), that is al

The best validated susceptibility variants for Parkinson's disease are located in the α-synuclein (SNCA) and microtubule-associated protein tau (MAPT) genes. Recently, a protective p.N551K-R1398H-K1423K haplotype in the leucine-rich repeat kinase 2 (LRRK2) gene was identified, with p.R1398H appearing to be the most likely functional variant. To date, the consistency of the protective effect of LRR

Recent studies of THAP1 (DYT6) have pointed out that late-onset focal dystonia can have a genetic basis. Familial late-onset primary dystonia has not been described in African- Americans. Six members of an African American family were affected by focal or segmental dystonia with a mean age at onset of 47 years (range, 45-50). Two additional individuals with milder clinical signs were classified as

In this study, low quality waste cooking oil with high total acid value, has been used for biodiesel production. The main factors affecting the reaction has been analysed using Response Surface Methodology (RSM). A quadratic model representing the interrelationships between reaction variables and free fatty acids (FFA) conversion has been developed. Analysis of variance (ANOVA) has been used for c

In recent years, much attention has been focused on the hydrogenolysis of biodiesel derived glycerol to other high value products for the sustainable development and efficient valorization strategies. In the present work, alumina-supported Ir catalyst was prepared by the incipient wetness impregnation method and tested in the glycerol hydrogenolysis reaction. The synthesized catalyst was character

This study aims to examine the effectiveness of the narrative tools in the modern Arabic poetry and take Al-baradony poetry as a model because it is a fertile field for academic studies and is as diverse as the curriculum to be studied by way of applications It has been studied in some respects and is still under taken for reasons. This study tries to examine the phenomenon of narrative style Al-b

This article addresses the big problems that Socotra island was facing in 2015; hurricanes, and the influence of war in Yemen.

Biological membranes do not only occur as planar bilayer structures, but depending on the lipid composition, can also curve into intriguing threedimensional structures. In order to fully understand the biological implications as well as to reveal the full potential for applications, e.g. for drug delivery and other biomedical devices, of such structures, well-defined model systems are required. He

The solid oxide fuel cell (SOFC) is an electrochemical device that converts the chemical energy present in reactant fuels into electrical energy and heat. Such conversion is given by the electrochemical reactions that occur inside the fuel cells when the reactant gases reach the so-called Three-phase Boundary (TPB). However, before the reactant gases can reach the TPBs, they have to pass through a

A numerical and experimental study on the conversion of a biomass particle is carried out to quantify the effect of homogeneous volatile combustion on the biomass pyrolysis. The numerical domain consists of a particle and its surrounding and the model considers detailed chemical kinetic mechanism for reaction of pyrolysis products. A detailed pyrolysis model is employed which provides the composit
