Lipid Profile of Coronary Heart Disease Patients: A Prospective Observational Study

Background: Coronary heart disease (CHD) remains the major cause of mor-tality and morbidity in the entire world population despite therapeutic ad-vances that control many risk factors. Lipid profile is regarded as an important factor in the development of coronary heart disease. There have been numerous studies confirming the association of hyperlipidemias with coronary heart disease in most of the Western as well as Asian countries of the world. But we have very little data on the relation between CHD and lipid profile. Aim of the Study: The aim of this study was to assess abnormal lipid levels and their association with coronary heart disease. Methods: This comparative observational study was conducted at the Department of Cardiology in M. Abdur Rahim Medical College, Dinajpur, Bangladesh from January 2019 to December 2019. Properly written consent was taken from all the participants before starting the main part of the investigation. Obeying inclusion and exclusion criteria of the study, a total of 131 participants were finalized as the study population. Among them, the Case Group was formed with 90 patients who had CHD, and with 41 healthy people, the Control Group was formed. the P-value of 0.242. Serum cholesterol concentration and HDL concentration were significant between the Case and Control groups in all age groups and the P-value was <0.0001 in every age group. Triglyceride concentration was significant between the Case and Control groups in 41 - 50 and 51 - 60 years age groups with a P-value of <0.0001. But in the >60 years age group, we did not find any significant correlation and there the P-value was 0.478. LDL concentration between the groups showed significant correlations between the Case and Control groups in 41 - 50 and 51 - 60-years’ age groups where the P values were found, <0.0001 and 0.0002 respectively. But in the >60 years’ age group, we did not find any significant correlation and there the P-value was 0.515. Conclusion: In this study, it was found that the total cholesterol, triglycerides, HDL cholesterol, and LDL cholesterol concentrations were significantly higher in coronary heart disease (CHD) patients.
A social network perspective on the bamboo ceiling: Ethnic homophily explains why East Asians but not South Asians are underrepresented in leadership in multiethnic environments.

In the United States, Asians appear disproportionately underrepresented in leadership roles, a puzzling phenomenon known as the "Bamboo Ceiling" (Hyun, 2005; Lu et al., 2020). We advance a social network explanation for this phenomenon: ethnic homophily. We theorize that East Asians (e.g., ethnic Chinese)-but not South Asians (e.g., ethnic Indians)-are less likely than other ethnicities to emerge as leaders in multiethnic environments partly because East Asians socialize more with ethnic ingroup members (other East Asians). Analyzing a survey of 54,620 Juris Doctor (JD) students from 124 U.S. law schools, Study 1 revealed that East Asians had the highest ethnic homophily of all ethnicities. Studies 2 and 3 examined friendship networks and leadership emergence in 11 class sections of new Master of Business Administration (MBA) students in a U.S. business school, and found that East Asians were the least likely to be nominated and elected as leaders. Social network analysis revealed that, compared to South Asians, Latinos, and Whites, East Asians exhibited higher ethnic homophily, which mediated their lower leadership emergence. These effects occurred for both East Asian internationals and East Asian Americans, and were robust after accounting for variables such as assertiveness (parallel mediator), network centrality, English proficiency, demographics, and personality. By integrating social network analysis into psychology, we identify ethnic homophily as one reason why the Bamboo Ceiling exists for East Asians but not South Asians. Moreover, by uncovering the negative link between ethnic homophily and leadership emergence, our research suggests that bonding with people from different ethnic backgrounds can facilitate individuals' leadership emergence in multiethnic environments.

Exploration of physical features of homogeneous–heterogeneous chemical action in a nanofluid film dispensed with MOS2 in diathermic oils

Topical endeavour is made to describe and search out the flow characteristics correspond to nano flow over thin liquid film dispensed with Molybdenum disulphide (MOS2) in a Casson fluid past an unsteady exponentially stretching sheet in porous medium. Due to this problem is modelled to boost the rate of thermal transfer of Diathermic oils, particularly, Kerosene-oil (KO) and Engine-oil (EO) by considering uneven heat source/sink. The governing equations are standardized into a system of ordinary differential equations by means of similarity transformations. The elucidation of the physical problem is conquered by shooting technique. The impact of pertinent parameters on flow and heat transfer is deliberated with the aid of graphs and tables. It is shown that the rate of heat transfer enhances by adding MOS2 in engine oil than MOS2 in kerosene oil, which improves its lubrication properties. The current conclusions are promoted academic research, tribology and polymer industry.

The problem of overcapacity and low utilization faced by several ports such as Kwangyang, Ulsan New Port and Phohang Youngil New Port can back up this. Furthermore as some ports are located closely sharing the same domestic hinterland the revitalization of the ports is not easy resulting in wasting resources with both regional and national aspect. This study, therefore, aims at providing an empirical results for the container port classification of the 5 ports such as Busan, Kwangyang, Incheon, Pyeongtaek and Ulsan. For this several time series data for the ports such as transshipment containers, import and export containers, origin and destination countries, and local origin and destination are analysed. Based on the results of the analysis the 5 container ports are classified together with their practical roles, and the functional overlap of the port including Phohang was analysed.Key words :Container port classification, BCG matrix, port concentration, hinterland concentration †교신저자 : 종신회원, namchan@hhu.ac. kr 051)410-4912 * 대표저자 : 연회원, goodtadpole@hotmail.com 051)644-0422 ** 연회원, sonhk21@koem.or. kr 02)3498-8502*** 연회원 ajura@hhu.ac. kr 051)410-4912

Recent advance in tunable diode laser spectroscopy with background RAM nulling for industrial applications

A limiting factor of tuneable diode laser spectroscopy (TDLS) with wavelength modulation spectroscopy (WMS) is the presence of background residual amplitude modulation (RAM) on the recovered 1st harmonic signal. The presence of this background term is due to direct modulation of the source laser power. This work presents a novel method to optically remove the unwanted background, with the major benefit being that measurement sensitivity can be increased. The recently developed phasor decomposition method1 (PDM), is a near IR (NIR) TDLS analysis technique that is used with the addition of the new RAM nulling method to recover gas absorption line-shapes. The PDM is a calibration free approach, which recovers the gas absorption line-shape and the isolated 1st derivative of the line-shape from the 1st harmonic signal. The work presented illustrates and validates the new RAM nulling procedure with measurements examining the 1650.96nm absorption line of methane (CH4) with comparisons to theory.
New open-winding configurations for high-power inverters

New configurations of high-power inverters suitable for AC motor drives and static VAr controllers are presented. A usual method of supplying large AC drives rated at more than several thousands of kilowatts is to combine the outputs of two inverters using inter-phase reactors. However, such inter-phase reactors have several disadvantages such as losses and acoustic noise. To solve these problems, several new configurations which combine two different type of inverters or converters to both terminals of the open windings are presented.
Doubly Coupled Designs for Computer Experiments With Both Qualitative and Quantitative Factors

Computer experiments with both qualitative and quantitative input variables occur frequently in many scientific and engineering applications. How to choose input settings for such experiments is an important issue for accurate statistical analysis, uncertainty quantification and decision making. Sliced Latin hypercube designs are the first systematic approach to address this issue. However, it comes with the increasing cost associated with an increasing large number of level combinations of the qualitative factors. For the reason of run size economy, marginally coupled designs were proposed in which the design for the quantitative factors is a sliced Latin hypercube design with respect to each qualitative factor. The drawback of such designs is that the corresponding data may not be able to capture the effects between any two (and more) qualitative factors and quantitative factors. To balance the run size and design efficiency, we propose a new type of designs, doubly coupled designs, where the design points for the quantitative factors form a sliced Latin hypercube design with respect to the levels of any qualitative factor and with respect to the level combinations of ar X iv :2 20 3. 06 33 5v 1 [ st at .

Surge performance of an underwater vehicle with a biomimetic tendon drive propulsion system

This article presents a study into the forward propulsion of a free swimming, custom-built biomimetic underwater vehicle called the RoboSalmon developed at the University of Glasgow, Scotland. As the name implies, the design of this vehicle is based on the dimensions of an Atlantic salmon. It realises fish-like propulsion through a tail assembly that utilises a tendon drive actuation system driven by a single servo motor. A brief overview of the experimental hardware is given followed by a discussion of the accompanying mathematical model of the vehicle. Experimental results are presented for straight swimming trials that show the surge velocity performance of the vehicle. In the context of forward swimming, the efficiency and power consumption of the vehicle are analysed, and the adverse effect of tail recoil is discussed.
RC-Amplifier Resonators for Active Filters

Active filters may consist of a cascade of isolated resonators, with each resonator supplying a single pair of complexconjugate poles. This paper supplies a detailed analysis of some RC -amplifier resonators whose characteristics are well suited for practical filters. The calculations are facilitated by a set of sensitivity identities. One resonator, taken from the Sallen and Key catalog, is shown to have extremely low passive sensitivities: S_{Z}^{Q} = \pm \frac{1}{6} for all passive elements. Active Q multiplication is used to extend the usefulness of the circuit. Analysis of the dualintegrator feedback resonator shows that it is notably insensitive to amplifier parasitics. Finally, the dual-integrator concept is realized in a resonator that uses only two amplifiers. The several resonators supply a range of useful pole- Q 's from low values to several hundred.
Use of face mask in COVID-19 pandemic-a review

The current novel corona virus disease 2019 (COVID-19) is a highly infectious disease of the respiratory tract and rapidly spreading all over the world in short span of time. In current COVID-19 pandemic, use of the face mask is becoming usual and ubiquitous for both health care workers and public individuals. Wearing face mask is one of the non-pharmaceutical interventions which need minimum cost and provide dramatic response for preventing the COVID-19 infection. Limited availability of the vaccine and inadequate supply of therapeutic options, face mask use is an important part for public health measures for restricting the COVID-19 spread. Regardless of the debate among medical community regarding global face mask production shortage, a greater number of countries in the world are moving ahead with recommendations or mandates for using face mask in public. As currently global shortage of N95/FFP2 respirators and surgical masks for use by health care workers in the hospitals, simple cloth masks will act as a pragmatic solution for the use of the public. General public often use the surgical mask or even filtering facepiece (FFP) masks irrespective of their need, resulting unnecessary shortage for needy individuals those are exposed to the patients or those are health care workers. So, this review article will clarify the indication of the different types of masks and their rational use in the current COVID-19 pandemic.

Credibility, Public Trust, and the Transport of Radioactive Waste Through Local Communities

The location of a national repository for the storage of nuclear waste remains elusive, which is due, in part, to widespread public opposition. Once a site has been selected, waste will be trucked from sources to the site. This study reports the results of a survey of 28 community leaders who live along a planned route in Oregon in which waste from Hanford, Washington, would be trucked to a disposal site under consideration in New Mexico. The results show that problems of credibility of the U.S. Department of Energy as a message source and public distrust of the agency's performance are embedded in the nsk communication of waste transport: A full partnership between the agency and local citizens may be a first step for restoring lost credibility and trust on transport issues.
Knockdown of lncRNA FOXD2-AS1 Inhibits Proliferation, Migration, and Drug Resistance of Breast Cancer Cells

Objective In order to investigate the effect of lncRNA FOXD2-AS1 on breast cancer cells proliferation, migration, and drug resistance as well as its molecular mechanism. Methods Real-time PCR was used to detect the expression of breast cancer tissues and cells from patients admitted to our hospital and the expression of lncRNA FOXD2-AS1 in MCF-7/ADR in adriamycin- (ADR-) resistant breast cancer cells. After interfering with or overexpressing lncRNA FOXD2-AS1 in MCF-7/ADR cells, cell proliferation, apoptosis, invasion, and migration were detected using CCK-8, flow cytometry, Transwell assay, and scratch test, respectively. The protein levels of PI3K, p-PI3K, AKT, and p-AKT in the PI3K/AKT signaling pathway were detected by Western blot. Results lncRNA FOXD2-AS1 was upregulated in breast cancer tissues and cells and increased cell drug resistance to ADR. Downregulation of lncRNA FOXD2-AS1 inhibited invasion and migration of MCF-7/ADR cells, promoted apoptosis, increased chemosensitivity of MCF-7/ADR cells, and inhibited the activity of PI3K/AKT signaling pathway in MCF-7/ADR cells. Conclusions lncRNA FOXD2-AS1 can promote the proliferation, invasion, migration, and drug resistance of breast cancer cells, inhibit apoptosis, and accelerate the development of breast cancer by positively regulating the PI3K/AKT signaling pathway.
Key Elements of Building Online Community: Comparing Faculty and Student Perceptions

This paper describes survey research of fourteen online courses where instructors and students were asked their perceptions about the challenges and essential elements of community in online classes. Results show that both instructors and students believe building community is very important. The majority of both students and instructors perceived it to be harder to build community online than in traditional classes. Additionally, while the majority of students and instructors both identified the same elements for building online community, there were significant ranking differences. Most striking among the differences was that students ranked instructor modeling as the most important element in building online community, while instructors ranked it fourth. Implications of these findings are discussed and recommendations provided for how instructors can model community behaviors in their online classes.
Circularly polarized microstrip antenna with electrically large property by using tilted periodical I‐shaped resonant inclusions

Usually circularly polarization (CP) of microstrip antennas is designed by using perturbed radiating patch or phase‐shift feeding network. In this paper, perturbation of inter‐medium metamaterial layer is proposed to tune the polarization characteristics of square microstrip antenna. As given in former design, effective media parameters of one I‐shaped metamaterial is in the band of ε>0 and μ<0 and electrically large property (ELP) of more than 4 times larger than conventional fundamental mode is achieved. By changing the geometry and placement location of periodical resonant inclusions, linear polarization as well as CP, either left‐handed CP (LHCP) or right‐handed CP, can be obtained without changing the square radiating patch and the feeding structure. Effective media parameters of different types of metamaterial are also extracted to confirm that ELP can be maintained. Finally, by using 45° tilted periodical I‐shaped resonant inclusions, one prototype with LHCP is fabricated for verification. Good agreement is achieved between the simulated and measured results. The proposed method gives new option to design antennas with different polarization states in millimeter wave or even terahertz wave band in future.
Development of a smart wing

Purpose – The objective of this paper is to develop an actuation system utilizing smart materials such as shape memory alloys (SMA) to control the position of an aircraft's flaps.Design/methodology/approach – The proposed smart wing consisted of SMA springs that were fixed at one end to the wing box toward the leading edge of the airfoil. The other end of each spring was attached tangentially to a rotating cylinder fixed to the flap. The springs were arranged in an upper and a lower layer to cause rotation of the flap in both the upward and downward directions. The spring actuators were controlled by the introduction of heat resulting from the applied current. A prototype of the smart wing was developed and tested to demonstrate the design concept.Findings – A prototype of a smart actuation system for controlling the flaps of an aircraft was successfully developed. Through the experimental and theoretical analyses conducted, the design was validated and showed strong potential for future application.Pract.
Inefficient integration during multiple facial processing in pre-morbid and early phases of psychosis

Abstract Objectives We used eye-tracking to evaluate multiple facial context processing and event-related potential (ERP) to evaluate multiple facial recognition in individuals at clinical high risk (CHR) for psychosis. Methods In total, 173 subjects (83 CHRs and 90 healthy controls [HCs]) were included and their emotion perception performances were accessed. A total of 40 CHRs and 40 well-matched HCs completed an eye-tracking task where they viewed pictures depicting a person in the foreground, presented as context-free, context-compatible, and context-incompatible. During the two-year follow-up, 26 CHRs developed psychosis, including 17 individuals who developed first-episode schizophrenia (FES). Eighteen well-matched HCs were made to complete the face number detection ERP task with image stimuli of one, two, or three faces. Results Compared to the HC group, the CHR group showed reduced visual attention to contextual processing when viewing multiple faces. With the increasing complexity of contextual faces, the differences in eye-tracking characteristics also increased. In the ERP task, the N170 amplitude decreased with a higher face number in FES patients, while it increased with a higher face number in HCs. Conclusions Individuals in the very early phase of psychosis showed facial processing deficits with supporting evidence of different scan paths during context processing and disruption of N170 during multiple facial recognition.
