Neutrophil to lymphocyte ratio correlate with syntax score in patients with non st elevation acute coronary syndrome

Introduction: In this study we aimed to investigate the correlation between the neutrophil to lymphocyte ratio (NLR) and severity of coronary artery disease (CAD) in patients with Non ST elevation acute Coronary Syndrome (NSTE-ACS) using the SYNTAX score (SXscore).Method: A total of 150 patients with NSTE-ACS who underwent coronary angiography were enrolled in the study. NLR was measured for all patients at presentation. The study population was then divided into 3 tertiles based on the SYNTAX trial results (1). The low syntax group (n = 25) was defined as those with an SXscore ≤ 22, the intermediate syntax group (n = 78) was defined as an SXscore ≥ 23 and < 33, and the high syntax group (n = 47) as those with an SXscore ≥ 33.Result: NLR was significantly lower in patients with a low SXscore compared to patients with an intermediate SXscore or high SXscore (2.4 ± 2 to 4.8 ± 2 and 6.9 ± 3, P < 0.001). Linear regression analysis revealed that NLR (coefficient β = 0.470, 95%CI: 1.273-1.935, P < 0.001) was significantly associated with the SXscore in patients with NSTE-ACS.Conclusion: Our results indicate that NLR is independently associated with the severity of CAD in patients with NSTE-ACS

Displacement Field Approximations for Force-Based Elements in Large Displacement Analyses

This paper investigates different approximation techniques for planar beam column elements in force-based methods. The three fields, introduced in this review, are: curvature-based displacement interpolation (CBDI) used in matrix-based flexibility formulations, linear displacement approximation applied in state space, and higher-order displacement approximation utilized again in state space. Using these three approximation fields, the responses and their accuracies in some systems are compared in examples. Finally, focusing on the accuracy and regarding the performed analyses, it seems that the computational cost is reduced and accuracy of responses is elevated in many engineering problems using the higher-order approximation field in state space

Preparation and characterization of acrylic polymer–nanogold nanocomposites from 3-mercaptopropyltrimethoxysilane encapsulated gold nanoparticles

100學年度張朝欽升等參考著作[[abstract]]In this study, acrylic polymer–nanogold nanocomposites and their cast films were prepared from an acrylic copolymer and 3-mercaptopropyltrimethoxysilane (MPS) stabilized gold nanoparticles by a sol–gel reaction. The acrylic copolymer was synthesized from methyl methacrylate (MMA) and 3-(trimethoxysilyl)propyl methacrylate (MSMA). The Si–OMe groups of MPS on the surface of gold nanoparticles (MPS–Au) provided the further reaction with the same groups of MSMA, hence the covalent bonds between polymers and MPS–Au nanoparticles were formed. FE-SEM images show MPS–Au nanoparticles are dispersed well in the prepared nanocomposites, and no large aggregation is occurred. TGA results indicate that the decomposed temperatures (Td) of low Au-content (0.1 wt.%) nanocomposites are higher than these of the acrylic copolymer and high Au-content (1.0 wt.%) nanocomposites. The temperature of maximum decomposed rate (Tp) of each prepared nanocomposite is higher than that of the acrylic copolymer. The hardness of the cast film increases with increasing the Au content. The results show the improved thermal stability and application potentials of the prepared acrylic polymer–nanogold nanocomposites.[[incitationindex]]SCI[[incitationindex]]EI[[booktype]]紙

A study on the status of saltwater intrusion in the coastal hard rock aquifer of South India

Groundwater of the coastal regions represents a fragile environment. A study has been attempted in the hard rock aquifer of the south-eastern part of India. A total of 135 groundwater samples were collected and analysed for major cations and anions. The domination of cations and anions was in the order of Na+ > Ca2+ > Mg2+ > K+ for cations and Cl− > HCO3− > SO42− > H4SiO4 > NO3− > PO4− > F− in anions. The water is neutral to alkaline in nature with pH ranging from 6.30 to 9.20 with an average of 7.57. The ions analysed were used for standard plots, ratio of different ions and correlation between them helped to evaluate the active hydrogeochemical process and extent of saltwater intrusion in the coastal aquifer. The electrical conductivity (EC) contour shows that the groundwater quality is poor along the coast due to saltwater intrusion. The Piper and chadda’s plot shows that most of the groundwater samples fall on Na–Cl water type may be due to saltwater intrusion in the eastern part study area. The ratios of Cl−/HCO3− ranged between 0.24 and 152.50 and have strong positive relationship with Cl− concentrations; it was found that about 30 % of the groundwater samples were strongly affected by the saline water in the study area. The Na+/Cl− ratios ranged from 0.20 to 3.73, and most of the groundwater samples fall close to the contamination region. Agricultural and salt pan land use pattern decrease the water quality due to impact of anthropogenic processes and seawater intrusion. Statistical analysis was also used to obtain the objectives, and it was found that the seawater intrusion is the major factor controlling the groundwater chemistry followed by other factors such as weathering and fertiliser impact
