Sectoral gdp convergence of selected RCEP countries: lead or lags?
No full textThe study investigates sectoral value-added convergence in selected RCEP countries by applying the non-linear
time-varying coefficients factor model suggested by Phillips and Sul (2007a) over the period of 1987-2015.
Structural convergence occurs, if income convergence progress is associated with sectoral convergence or
disaggregated level. Interestingly, this investigation finds income converge at the aggregate level. To investigate
further, further clustering algorithm is applied and resulted in three clubs, indicating advanced countries (Japan,
Singapore and Korea) lead club, Upper-middle income countries (Malaysia, China and Thailand) as second club,
and finally lower middle income (Indonesia, Philippines and India) form another club. The three sector
hypothesis states that, inter sectoral convergence is anticipated to appear whenever the less developed nations
are capable of closing the income disparity with those advanced nations as Asian in this study. Convergence in
Income per capita was quite rapid, indicating the highest level of convergence at sectoral level. For robustness,
this application offered the measures of value added convergence in five sectors namely, agriculture,
manufacture, service, construction and mining sectors. The study shows an obvious indication for Asian catching
up countries to form large clusters that shall be useful in policy formulation for further integration of RCEP
Challenges and Strategies to Conduct Research at Restricted Rohingya Refugee Camps of Bangladesh
No full textAbstract: Rohingya refugees have been living in Bangladesh for decades. Before the latest 2017 exodus only two registered camps and some unregistered spots lying with the registered camps were present in the Cox’s Bazar area of Bangladesh. However, now 33 makeshift camps are hosting around one million Rohingyas coming from Myanmar. The government of Bangladesh prohibits visitors’ access in those camps without prior official permission. The bureaucratic hurdles for securing permission from the respective office to get into the camps are lengthy, difficult and time consuming. Besides research in any humanitarian settings like Rohingya camps having vulnerable communities require some special ethical consideration. This paper draws fieldwork experiences among the makeshift camps of Cox’s Bazar, Bangladesh. It sheds light on practical experience and challenges in the field and the required strategies taken by the author to do a productive fieldwork overcoming all the challenge
Food taboo of taking pineapple and milk at a time
Full text linkThe purpose of this study was to assess whether potential toxic interactions occur between the pineapple and milk following oral administration in rats by comparing clinical signs, hematological and biochemical parameters with the normal control and toxic standard groups. Pineapple and milk solutions were made by 1:1 (PMS1) and 2:1 (PMS2) ratio, administered 12 mL/kg body weight. Forty rats were equally divided into 4 groups treated for 3 days: a) normal control (only vehicle treated); b) toxic standard (CCl4 was suspended in corn oil, 20% v/v; treated 1.25 mL/kg), c) PMS1 and d) PMS2 groups. CCl4 administration altered the normal behavior, changes gross and microscopic morphology. Toxicity related hematological and serum biochemistry changed significantly (p<0.05) than the normal group. However, all these clinical and pathological changes were completely absent in PMS treated groups. These results suggest that taking pineapple with milk is not toxic and this food taboo is wrong

Progress in Electrochemical Biosensing of SARS-CoV-2 Virus for COVID-19 Management
No full textRapid and early diagnosis of lethal coronavirus disease-19 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an important issue considering global human health, economy, education, and other activities. The advancement of understanding of the chemistry/biochemistry and the structure of the SARS-CoV-2 virus has led to the development of low-cost, efficient, and reliable methods for COVID-19 diagnosis over “gold standard” real-time reverse transcription-polymerase chain reaction (RT-PCR) due to its several limitations. This led to the development of electrochemical sensors/biosensors for rapid, fast, and low-cost detection of the SARS-CoV-2 virus from the patient’s biological fluids by detecting the components of the virus, including structural proteins (antigens), nucleic acid, and antibodies created after COVID-19 infection. This review comprehensively summarizes the state-of-the-art research progress of electrochemical biosensors for COVID-19 diagnosis. They include the detection of spike protein, nucleocapsid protein, whole virus, nucleic acid, and antibodies. The review also outlines the structure of the SARS-CoV-2 virus, different detection methods, and design strategies of electrochemical SARS-CoV-2 biosensors by highlighting the current challenges and future perspectives
Design of Transition Metal Oxide and Phosphide Nanomaterials: Their Catalytic Activities
No full textThis thesis is focused on developing transition metal-based oxide and phosphide nanomaterials for catalytic application in energy conversion and the organic transformation reaction. The research projects presented in this thesis are: (1) the design and synthesis of transition metal doped ZnO catalysts for the oxygen reduction reaction (ORR), (2) the development of mesoporous FeP and CoP materials as hydrogen evolution reaction (HER) catalysts for electrochemical water splitting, and (3) the fabrication of different ZnO morphologies for coumarin synthesis by the Knoevenagel condensation.
The first chapter describes the significance and background of the three research projects. We emphasize the current challenges in developing HER and ORR catalysts for water electrolysis and fuel cell application. Additionally, the importance of coumarins and challenges in their synthesis via the Knoevenagel condensation is included in this chapter.
The second chapter contains the synthesis and characterization of transition metal (Mn, Fe, Co, and Ni) doped ZnO nanocrystals. The goal of this study is to develop ZnO based low-cost ORR catalysts. Single-doped and multi-doped transition-metal ZnO samples are synthesized to investigate the effects of doping in the ZnO structure and their activities for ORR. The ORR activity of the ZnO samples is governed primarily by the oxygen vacancies created as a result of the incorporation of dopant elements.
The third chapter is comprised of developing mesoporous FeP and CoP nanomaterials as an efficient HER catalyst. A noble approach, the inverse micelle sol-gel method, is utilized to synthesize mesoporous FeP, Co-FeP, CoP, Ni-CoP, and Ni-CoP/CNT materials. The mesoporosity and HER activity of the materials are monitored with the dopants and CNT support. The HER activity of the catalysts predominantly alters with the charge-transfer capabilities of the materials.
The fourth chapter includes the preparation of different ZnO morphologies as catalysts for coumarin synthesis. The ZnO properties of different morphologies and their catalytic activities for coumarin synthesis by the Knoevenagel condensation reaction are examined. Catalysts synthesized using methanol show the highest activity. The enhanced activity of the ZnO synthesized in methanol is attributed to the combined effects of relatively high surface area, pore volume, and pore sizes of the materials
