Forecasting The Electricity Consumption in Myanmar (1961-62 to 2019-2020) (The' Mya Thawdar Tin, 2022)

Electricity plays a very important role in the economic development for the countries. This study investigates the forecasting of electricity consumption in Myanmar by using annual time series data for the period from 1961-1962 to 2019- 2020. The secondary data of electricity consumption in Myanmar are obtained from Myanmar Statistical Year Books published by Central Statistical Organization, Ministry of Planning and Finance. The electricity consumption is one of the most important energy sources to develop the human living standard, industrialization and economic for a country. Moreover, the electricity consumption is expected to provide well organized planning and policy for the development of the country in future. The time series analysis of electricity consumption in Myanmar are analyzed and based on the most adequate model chosen among ARIMA Model, Brown’s Double Exponential Smoothing Model and Holt’s Double Exponential Smoothing Model. According to the results of study, the values of MAE and RMSE for Brown’s Double Exponential Smoothing Model are smaller than the other models. Therefore, Brown’s Double Exponential Smoothing Model is the most suitable and used to forecast the electricity consumption in Myanmar for the next five years. By the results of the study, the electricity consumption in Myanmar is likely to continue on an upward trend in the next years

Immune System in COVID-19: Is It Temporarily Defeated While Conquering?

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is spreading worldwide and becomes a major cause of mortality. In addition to major pathology in lungs such as pneumonia or respiratory failure, multiorgan failure and frequently haematological disorders such as thromboembolic manifestations are leading causes of mortality. This study reviews the interaction of the immune system with target cells, the role of cytokines and other components such as complements encountered in the pathophysiology of major disease processes and possible post-recovery complications. Although there are some clinical effects induced by strong immune reactions, long term immunity against the virus is found in the majority

Escape from Original Home: Do Metastatic Cells Stay Dormant or Destructive?

Metastasis is defined as tumour implants discontinuous with the primary tumour. It is responsible for most cancer-related mortality. Many factors relating to the tumour and host factors are involved in the presence of metastasis and the long-term prognosis of the disease process. This study observed available literature and aims to emphasise tumours and their interaction with the tumour microenvironment. Epigenetic and genetic influences on pathogenesis, tumour and microenvironment interaction, role of epithelial-mesenchymal transition in metastasis are essential determinants of advanced malignant diseases. Early detection of metastatic disease is an essential part. The histopathological aggressiveness of a tumour and its biological behaviour determine the probability of metastasis and advanced disease. Understanding these factors has a benefit to improving the current therapies and diagnostic approaches to an advanced level, leading to the prevention of metastasis and more successful management of patients

XRD and SEM Analysis, and Semiconductor Type Determination of TiO2 for Dye-sensitized Solar Cell

Titanium dioxide (TiO2) is a wide band-gap n-type semiconductor. Anatase TiO2 is the most common structure used in high performance dye-sensitized solar cell (DSSC). Nanoporous TiO2 serves double-duty as an electron acceptor and a scaffold to hold large numbers of dye molecules in DSSC. The porosity of TiO2 is a key feature as it has roughly a thousand times greater a surface area than the equivalent flat area. In this work, TiO2 crystallite size (43.55 nm) has been calculated by using XRD data, and the morphology and the grain-size of TiO2 (average grain size of 0.2 mm ~ 0.3 mm) with different solvents have been also studied by SEM

The investigating officer and forensic team immediately visited the crime scene and checked the possible foul play. Autopsy study supported the suicidal hanging with motive

Preferred modalities for learning anatomy: medical students’ opinion

Learning anatomy is the basic and essential component of medical study when students start to learn in medical career. Since five hundred years ago, the human cadaver has been used as the silent mentor for students in learning anatomy. Later, pre-dissected specimens were used in addition to hands-on dissection of human cadaver. Current advances promote the use of anatomical models as well as plastinated specimens. This study focused on analyzing the preference of students towards different learning modalities available for anatomy teaching. It was conducted on first year medical students at the Faculty of Medicine and Health Sciences, University Malaysia Sabah (FPSK, UMS). A total of 76 students (27 males and 49 females) participated in this study. Out of 76 students, 57 (75%) students preferred using human cadaver for anatomy learning. Four students (5.3%) opted for plastinated specimen while 15 students (19.7%) chose the plastic model. Knowledge gained in learning Anatomy was said to be easier from cadaver (67.1%), followed by plastinated specimen (35.5%) and plastic models (52.6%). In the present study, 97.4% responded that plastic model was easier to apply their knowledge in objective structured practical examinations. The present study found that using cadaver was still favoured by medical students. Further studies are required to determine the preference between hands-on cadaveric dissections versus pre-dissected specimens

Forensic age estimation in living children: how accurate is the Greulich-Pyle method in Sabah, East Malaysia?

Background: The Greulich and Pyle’s Radiographic Atlas of Skeletal Development of the Hand and Wrist (GP Atlas) is the most widely used method of determining the bone age (BA) of a child. It is also a widely accepted method for forensic age determination. As there is limited local bone age data for forensic age estimation, the purpose of this study was to assess the accuracy of the GP Atlas for forensic age determination in living Sabahan children. Method: This study recruited 182 children between the ages of 9 years to 18 years. BA estimation of the left-hand anteroposterior radiographs were performed by two experienced radiologists using the Greulich-Pyle method. Results: The BA estimates from two radiologists had very high interobserver reliability (ICC 0.937) and a strong positive interobserver correlation (r > 0.90). The GP method, significantly and consistently underestimated chronological age (CA) by 0.7, 0.6 and 0.7 years in overall children, boys and girls respectively with minimal errors. Mean absolute error and root of mean squared error for overall children was 1.5 and 2.2 years respectively, while mean absolute percentage error was 11.6%. This underestimation was consistent across all age groups but was statistically significant only at 13–13.9 and 17–18.9 years old age groups. Conclusion: Despite high interobserver reliability of BA estimation using the GP Atlas, this method consistently underestimates the age of the child in all children to a significant degree, for both boys and girls across all age groups, with an acceptably low level of error metrics. Our findings suggest that locally validated GP Atlas or other type of assessments (artificial intelligence or machine learning) are needed for assessment of BA to accurately predict CA, since current GP Atlas standards significantly underestimated chronological age with minimal error for children in Sabah. A larger population-based study would be necessary for establishing a validated atlas of a bone age in Malaysia

Study on the Treatment of Liquid Waste from Rare Earth Processing by Chemical Precipitation

This paper describes treatment of liquid waste from rare earth processing by chemical precipitation. Monazite ore from Moemeik Myitsone area was used as raw material for rare earth processing. Large amount of solid and liquid wastes were generated after rare earth oxide processing. Solid waste was stored in the storage tanks and liquid waste needed further treatment before discharges to the environment. Research process serves the purpose of reducing the volume of the waste as much as possible to protect men and the environment from any undesirable effects for the present and future generation. Treatment methods are selected based on the composition, quantity and form of the waste materials. The used method is chemical precipitation method. For liquid waste treatment, the most coagulation treatment used is the Fe +++ co-precipitation followed by settling, decantation and filtration of the supernatant liquid. The efficiency of the process can be improved by careful control of the pH and the settling the decantation procedure. The sludge was filtered, dried in oven and collected in plastic bags and temporary stored in 100 liters plastic drums.   Finally all of the decontaminated effluents are safety discharged to the environment. All of the experiments were analyzed by the X- ray Fluorescence Spectrometer (XRF). Before treatment, thorium and uranium contained <2000 ppm,  < 300 ppm and this is in the low level waste. After treatment result in decant water gives uranium (< 1 ppm) and thorium (< 10 ppm).According to the threshold limits for the UK radioactive classification system,   liquid waste from rare earth processing was less than (0.4 Bq/g) and this range is in exempt waste and can be discharge to drain and to the environment safety. The safety regime was in place and improved simultaneously by survey monitoring by using Alert Monitor 4 meter Scale in USV/H
