THE IMPACT OF THE SILENT ENEMY (COVID-19 PANDEMIC) ON THE MARKETING EFFORTS UNDERTAKEN BY THE AUTOMOTIVE INDUSTRIES IN MALAYSIA

The impact of a dangerous pandemic to human life is not a new chapter in human history. However, the silent enemy (Covid-19) pandemic crept from Wuhan City, Hubei Province, China, at an exponential rate that it shifted the rhythm of the world. The crisis that started in China has become a global crisis that crippled many nations in terms of health and economy. From the events that have happened and still happening, we can notice that humans were not prepared for the onslaught of this killer pandemic. The businesses and industries in Malaysia were also not spared by this killer pandemic. One of the hard-hit industries, due to this pandemic is the automotive industry in Malaysia. Therefore, this research aims to discover how Covid-19 pandemic has impacted the marketing efforts undertaken by the automotive industry in Malaysia. Consequently, to achieve the objective of this research, the survey technique is used to develop a detailed profile, which is gathered from 337 out of 450 formal standardized questionnaires sent online to marketers at twelve automotive companies in Malaysia. This research applied the quantitative methods to yield empirical results and validations that answer the research question. The literature examined the areas of the marketing concept, context and strategies to fill the gap and to determine the significant relationship between the Covid-19 pandemic and the marketing efforts undertaken by the marketers of the automotive industry. The analysis shows that Covid-19 pandemic has a significant relationship and correlated negatively to marketing efforts. The hypothesis proved that Covid-19 pandemic has a significant relationship with marketing efforts. Thus, this study could also help all other businesses and industries in Malaysia stay vigilant and overwhelm the assault of this silent enemy. By making a shift to its marketing concept, context and strategies, the automotive industry could regain its momentum from the onslaught of the silent enemy (Covid-19) pandemic.

Protolith Oceanic Island Arc dari Granitoid Tipe M dan I di Karangsambung, Kebumen, Jawa Tengah

Granitoid rocks which found at Luk Ulo melange complex as rock fragments with pale gray colour and faneritic texture. Petrogenesis and geotectonic of the granitoid is under debate. Some geologists consider as plagiogranite, which is formed from the Mid Ocean-ridge (MOR); or leucogranite which is formed from continental collision, and others argue as arc-related granitoid type. The field studies ware carried out on 5 (five) tracks around Luk Ulo River and 1 (one) track at Lokidang River. The pale grey Karangsambung granitoid is composed of the mainly K-feldspar (34-55%), plagioclase (10-25%) and quartz (25-35%), and chemically contains SiO2 (61.25 - 66.06%); Al2O3 (13.94 – 14.61%), K2O (2.53 - 4.00%), Na2O (3.42 - 4.10%), CaO (2.32 - 4.76%), Fe2O3 total (5.85 – 8.71%), MgO (0.98 – 1.97%). The granitoid is M- and I-type that were formed at 760o - 800o C with a depth of about 20-30 km, resulting from the differentiation of magma from a fragment origin of the K-enriched oceanic island arc originating from drifting of the IAB fragment. The sample of basalt 17D has a relatively high of Nb/Ta ratio (20), low Rb (<2 ppm), low Ba (17 ppm), and is interpreted as interacting with MORB mantle magma containing rutile-melt;whereas quartz monzonite (17A) has a relatively low of Zr/Sm ratio (3.86), which is indicated to have been contaminated by a carbonatite magma. The spidergram pattern of mantle metagabbro (sample no. 13) similar with the basalt from IAB-Bransfield Strait (Antarctica). Results of a comprehensive geochemical study proposes that the current condition of the Karangsambung zone is part of geotectonic of ACM-Eurasia, that composed of a combination of four rock fragments, i.e. (a) the rocks which sourced from IAB fragments, (b) mantle MORB, (c) continental crust from the origin of ACM-Eurasia, (d) the origin fragment from carbonatite magma.

Incidence of Metallo-β-Lactamase Producing Pseudomonas Aeruginosa Isolates and Their Antimicrobial Susceptibility Pattern in Clinical Samples from a Tertiary Care Hospital

Background and objectives: Pseudomonas aeruginosa, most common pathogen causing nosocomial infections, acquire drug resistance to more than one antimicrobial class along with production of metallo-β lactamases (MBL) is one of the most worrisome resistance mechanism. The aim of our study is to find the incidence of MBL in Pseudomonas aeruginosa isolates and their antimicrobial susceptibility pattern. Materials and Methods: The study included 127 non-repetitive clinical isolates of Pseudomonas aeruginosa from various samples isolated from October 2010 to October 2011, in department of Microbiology, Mahatma Gandhi Medical College and Hospital, Jaipur, Rajasthan. The following tests were used Imipenem and EDTA combined disc test, Double disc synergy test (DDST) using Imipenem and EDTA and MBL E-test along with antibiotic susceptibility testing. Result: The incidence of MBL P. aeruginosa was 15/127 (11.81%) in our study. The incidence of MBL pseudomonas was maximum in ICU patients (30%), followed by IPD patients (9.6%). None of the OPD sample grew MBL in Pseudomonas. Conclusion: Combined disc / DDST using ceftazidime have other ceftazidime resistance mechanisms; will not show MBL production and therefore, imipenem disc should be used for screening of MBL.
EFFECT OF DONOR IMPURITY ON AHARONOV–BOHM OSCILLATIONS IN A DOUBLE QUANTUM RING WITH GAUSSIAN CONFINEMENT

In this paper the effect of donor impurity on the Aharonov–Bohm oscillations of the electronic states in a double quantum ring with Gaussian confinement has been studied. Three different impurity positions: namely in the inner ring, in the outer ring and in the barrier between the rings, have been considered. It is shown that the energies of the two lowest states are almost constant, while for the higher levels the Aharonov–Bohm oscillations are observed. The obtained results indicate on the possibility of the effective control of the quantum states by means of donor impurity and external magnetic field.

A Method of Estimating Carcass Fat and Fat-Free Weights in Migrant Birds from Water Content of Specimens

this seemed to be the northern limit of their range for at least another decade. The eventual expansion that now extends throughout the Palouse Prairie country of northern Idaho and eastern Washington and into the Spokane area, while well known to local ornithologists, has apparently never been thoroughly documented. There is now evidence that a similar invasion has reached the vicinity of Missoula in western Montana. The AOU Check-list (1957), in outlining the range of this species, mentions Montana only as follows: "In winter . casual north to Alberta (Topaz Lake) and Montana (Santon Lake). " Davis, in his checklist of the birds of Montana (Proc. Montan Acad. Sci. 16:5, 1956) mentio s sight records of Hou e Finches in Helena and Bozeman. Additional Montana recor s include the following by Dr. P. L. Wright, Department of Zoology, U iversity of Montana, and myself. Wright's observations were near his home in southeastern Missoula, while mine included both residential and rural areas near the southern outskirts of the city (table 1). From these records there seems to be little doubt that the House Finch is well on the way toward becoming an established resident in this area.
Genetic variability among Coleus sp. studied by RAPD banding pattern analysis

Genetic improvement of medicinal plants depend on the existence, nature and extent of the genetic variabiles available for manipulation. Genetic analysis with random amplification of polymorphic DNA markers has been extensively used to determine genetic diversity among Coleus sp. and to identify the best quality for human consumption and its medicinal purpose. The objectives of the present study were to assess molecular variation among Coleus amboinicus, Coleus aromaticus and Coleus forskohlii and to determine the level of genetic similarity among them. Analyses carried out include random amplification of polymorphic DNA (RAPD) on three strains of Coleus sp. and random primers were used for PCR. Electrophoresis on denaturing acrylamide gels improved RAPD reproducibility and increased the band number. In this study, the primer OPW 6 and OPW 7 gave reproducible results and the band profiles.
Reproducible Electrodeposition of Hydrogen Molybdenum Bronze Films and Electrochemical Reduction of Carbon Dioxide

Article history: Received 15 July 2020 Accepted 06 August 2020 Available online 26 August 2020 Electrochemical synthesis of hydrogen bronze films including molybdenum, tungsten and vanadium are useful electrocatalytic films. This paper describes reproducible hydrogen molybdenum bronze film formation on indium tin oxide and carbon paper substrates by electrodeposition. Film formation is a kinetic process dependent on concentration, time and potential. Bulk electrolysis over time determined the dependence of film thickness on time of deposition. Once the films were prepared, the films were characterized by thickness, conductivity, XPS and X-Ray Diffraction. Cyclic voltammetry in dilute sulfuric acid confirmed that these films are not electrochromic. Hydrogen bronze films on conductive carbon paper were also prepared. Carbon dioxide bubbled into 0.5 M NaHCO3 using a hydrogen bronze film as the working electrode resulted in formate quantified by ion chromatography. Cyclic voltammetry and Tafel plots using the as deposited films in 0.5 M NaHCO3 saturated with CO2 showed catalytic activity toward reduction of carbon dioxide. A Farradaic efficiency of 8% was obtained with an applied potential of -0.4 V.
Two Strategies to Improve the Differential Evolution Algorithm for Optimizing Design of Truss Structures

The performance of differential evolution (DE) mostly depends on mutation operator. Inappropriate configurations of mutation strategies and control parameters can cause stagnation due to over exploration or premature convergence due to over exploitation. Balancing exploration and exploitation is crucial for an effective DE algorithm. This work presents an enhanced DE (EDE) for truss design that utilizes two new strategies, namely, integrated mutation and adaptive mutation factor strategies, to obtain a good balance between the exploration and exploitation of DE. Three mutation strategies (DE/rand/1, DE/best/2, and DE/rand-to-best/1) are combined in the integrated mutation strategy to increase the diversity of random search and avoid premature convergence to a local minimum. The adaptive mutation factor strategy systematically adapts the mutation factor from a large value to a small value to avoid premature convergence in the early searching period and to increase convergence to the global optimum solution in the later searching period. The outstanding performance of the proposed EDE is demonstrated through optimization of five truss structures.
Understanding the thermal conductivity variations in nanoporous anodic aluminum oxide

Anodic porous alumina (AAO) templates, also known as nanoporous anodic alumina (NAA) platforms or membranes, are widely used as templates in nanoscience and nanotechnology. During fabrication, characterization, or device performance, they are sometimes exposed to heat treatments. We have found that the thermal conductivity of AAO is strongly dependent on the temperature at which the sample is exposed, showing a certain variation even at very low temperatures, such as 50 °C. Because of this, we have performed a study of the thermal conductivity (k) variation for different AAO templates using 3ω-Scanning Thermal Microscopy (3ω-SThM) as a function of the annealing temperature. The AAOs studied in this work were produced in the most common electrolytes – sulfuric, oxalic, and phosphoric acids, and heated from RT up to 1100 °C. To explain these variations in an in-depth and enlightening manner, structural characterization of the different nanoporous aluminas has been performed. It is shown that even at low temperatures, below 100 °C, the AAOs lose water, which explains the reduction of their thermal conductivity. The minimum value of thermal conductivity can be found for AAO samples prepared in sulfuric acid and heated at 100 °C (0.78 ± 0.19 W m−1 K−1), which corresponds to a 50% reduction from the original value. It has also been found that for AAO annealed above 950 °C, the variations in the thermal conductivity are mainly related to phase transitions from amorphous to crystalline alumina and gas evolution of CO2, or SO2 and SO, depending on the electrolyte used during the anodization. This is also an indication that the counter ions are trapped inside the alumina template during the anodization process. And, their presence determines the crystallization temperatures at which the different crystalline phases are formed. And so, the variations in thermal conductivity are measured. The thermal conductivity values of the AAO can reach values as high as 4.82 ± 0.36 W m−1 K−1 for AAO samples prepared in oxalic acid and heated up to 1300 °C. We consider that the understanding of the changes in their thermal conductivity can explain the different values in the thermal conductivity of the AAO template found in the literature and draw some attention to the importance of the history of the AAO platforms that are to be used or measured, since it may change the final thermal properties of the template or device.
Electioneering activities and their impact on the Ghana Stock Exchange

Orientation: Literature is scanty on the euphoria around Ghana’s electioneering activities and their impact on economic activities. Research purpose: This paper studies electioneering activities and their impact on the Ghana Stock Exchange (GSE) returns. Motivation for the study: Literature have established that political risk is statistically significant in emerging stock markets and from 5 January to 7 December 2016, the GSE lost 23.47% of its trading values. Hence, this paper finds it imperative to examine whether electioneering activities indeed have an impact on GSE. Research approach/design and method: Using daily data span from 5 January 2016 to 7 December, 2016. The autoregressive distributed lag (ARDL) bound test approach to cointegration and Granger causality test was used to examine the data. Main findings: The result suggests that electioneering activity impact negatively on the GSE returns both in the short-run and long-run, but its cause is not clear. It impacts creates arbitrage opportunities for investors and may punish the political party in power. Practical/managerial implications: Political parties in power should recognize that electioneering activities creates a dilemma between regaining power or managing the economy. Contribution/value-add: Ghana’s electioneering activities disproves some investment theories, that is, investors assume risk may not reflect their expected return since the stock market efficiency is nullified by arbitrage opportunity.
Opposing Functions for the Wilms' Tumor Protein 1 (WT1) in Tumorigenesis

Abstract: The Wilms’ tumor 1 ( WT1 ) gene encodes a transcription factor that was among the first tumor suppressor genes to be identified. Dependent on the splice variant, some WT1 isoforms can function as transcriptional regulators, whereas other WT1 proteins are presumably involved in RNA processing. The mechanisms by which WT1 regulates transcription and the identification of bona fide target genes have been difficult to study, which is partially due to the complex nature of the gene and its context specific functions. While the role of WT1 as a tumor suppressor in Wilms’ tumor is widely accepted, considerable evidence points to an oncogenic function in other tumors. Recent studies have provided new insights into the underlying mechanisms that lead to the development of Wilms’ tumor. In addition, a conditional Wt1 knockout mouse model and RNAi-mediated screening approaches have uncovered new functions for WT1 in development and tumorigenesis. Keywords: Apoptosis, HTRA2, Igf2 , oncogene, senescence, WT1.

Combine Business Model Canvas, Blue Ocean Strategy, and Analytical Hierarchy Process to Develop Business Model of Malkita Mall Jakarta

In the midst of the issue of shifting the mall’s function from shopping to gathering places, Malkita Mall is trying to increase occupancy so that it can increase company margins. To achieve this goal, Malkita Mall needs a new business model. The design of the business model was prepared using the Business Model Canvas. Qualitative research is applied to carry out internal and external analysis. Internal analysis is carried out to get the company's current condition. Whereas external, macro and industry analysis are used to identify opportunities and threats in the next few years. Based on opportunities and threats, an ideal business model was formed for Malkita Mall. Next is an analysis of the gap between the current business model and the ideal business model. If the current conditions have reached the ideal conditions will be the strength of the company, but if there is a gap will be a weakness of the company. To close this gap, three new business model prototypes were developed using the Blue Ocean Strategy, the "Unicorn Frappuccino" prototype, the "Thai Tea" prototype, and the "Milkshake Monster" prototype. Looking at the company's strengths and weaknesses, not all prototypes can be used. Therefore, an objective election is carried out using the Analytic Hierarchy Process method to get the right business model. The "Thai Tea" prototype offers a value proposition in the form of a new variety of tenants is combined with the layout of the outlets displaying branded goods. This value proposition is offered to millennial visitors who have the potential to increase tenants' turnover. In the long run, an increase in sales turnover will trigger an increase in the number of tenants which results in an increase in occupancy. The high occupancy rate has an impact on increasing rental income, service charges, and utilities, as well as lowering operational costs, especially for public areas. An increase in revenue accompanied by a decrease in costs will automatically increase the company's margins.
