Bayesian frequentists: Examining the paradox between what researchers can conclude versus what they want to conclude from statistical results
Authors: Haucke Matthias , Miosga Jonas , Hoekstra Rink , van Ravenzwaaij Don
Published: March 2020

A majority of statistically educated scientists draw incorrect conclusions based on, arguably, the most commonly used statistical technique: null hypothesis significance testing (NHST). Frequentist techniques are often claimed to be incorrectly interpreted as Bayesian outcomes, which suggests that a Bayesian framework may fit better to inferences researchers frequently want to make (Briggs, 2012). The current study set out to test this proposition. Firstly, we investigated whether there is a discrepancy between what researchers think they can conclude and what they want to be able to conclude from NHST. Secondly, we investigated to what extent researchers want to incorporate prior study results and subjective beliefs in their statistical inference. Results show the expected discrepancy between what researchers think they can conclude from NHST and what they want to be able to conclude. Furthermore, researchers were interested in incorporating prior study results, but not subjective beliefs, into their statistical inference.

The Effects of Physical and Non-physical Investments of Government Expenditure in Education and Health Sectors on Human Development Index in Pekanbaru City
Authors: Fatria Muhammad Akbar
Published: March 2020

In this current globalization era, human resources investment is necessary for each country to improve the index of human development and economic growth, many countries have succeeded in economic growth by relying on human resources despite not having abundant natural resources. However, the success of resource investment is also strongly influenced by the availability of supporting facilities and infrastructure. Based on data of physical and non-physical investments of government expenditure in education and health sectors from 2007-2017, shows a positive trend with relatively increasing value. Meanwhile, based on data of human development index progress in Pekanbaru city in recent years showed a relatively declining value. This contradicts the theory of endogenous romer which explained that when the government or private sectors invest in human resources, it will encourage the improvement of human resources quality that reflects the progress of human development index. This study uses secondary data, namely government physical and non-physical expenditure data in the field of education and health in Pekanbaru City on Regional Budget in 2010-2017. The independent variable is government physical and non-physical expenditure in education and health sectors. While the dependent variable is the Human Development Index. The analysis method used is OLS (Ordinary Least Square) method where the data used are analyzed quantitatively using statistical analysis, namely multiple linear regression equations. Based on the results of research, government physical expenditure in education and government non-physical expenditure in the health sector does not significantly influence the human development index in Pekanbaru City. While government non-physical expenditure in education and government physical expenditure in health significantly affect the human development index in Pekanbaru City. Furthermore, for physical investment where in this research is the government physical expenditure in education and health sectors simultaneously has a significant effect on the human development index in Pekanbaru City. Whereas for non-physical investment where in this study is government non-physical expenditure in education and health sectors simultaneously has a significant effect on the human development index in Pekanbaru City.
“Whatever Works”: Innovations in the Treatment of Hemophilia in the United States 1783–1950
Authors: Rushton Alan R.
Published: March 2020

Treatment of the bleeding disorder hemophilia in the nineteenth century was empirical, based on clinical experience. Medications, transfusions of human or animal blood, and injections of blood sera were utilized in an attempt to halt life-threatening hemorrhages. After 1900, the application of clinical laboratory science facilitated the utilization of anti-coagulated blood and donor blood compatibility tests for safer emergency transfusions. But repeated transfusions produced blood incompatibility that limited future utilization. Investigation of hormones and snake venom as coagulants appeared hopeful during the 1930s, but plasma globulin research during World War II resulted in the isolation of antihemophilic factors that promptly reduced hemorrhage. Their application to bleeding episodes resulted in a more normal life for hemophiliacs after 1950.
Re-Imagining “Serving Time” in Indigenous Communities
Authors: Murdocca Carmela
Published: March 2020

L’article 81 de la Loi sur le système correctionnel et la mise en liberté sous condition permet aux collectivités autochtones de superviser le soin et la garde des délinquants autochtones. Bien que l’article 81 ne décrive pas comment les collectivités autochtones doivent s’y prendre, la prestation de garde et de soin prend communément la forme de centres de guérison, communément appelés pavillons de ressourcement. Cette loi a le potentiel de permettre aux collectivités autochtones, dans tout ce qu’elles entreprennent, de configurer leurs propres accords en vertu de l’article 81 de façon à ce qu’ils correspondent à leurs capacités et à leurs besoins spécifiques. Malgré le potentiel de l’article 81, peu de programmes de cette nature sont offerts aux femmes autochtones détenues dans des prisons fédérales. Cet article présente les résultats de deux séances d’engagement communautaires avec des femmes autochtones et des chefs de diverses communautés autochtones du Manitoba au sujet des femmes autochtones détenues dans des prisons fédérales qui purgent leur peine dans leur collectivité. L’article décrit les connaissances et les points de vue des communautés qui ont participé aux séances d’engagement et démontre la nécessité de faire appel à l’expertise autochtone et de mieux comprendre sur le plan local les obstacles, les possibilités et les limites de l’article 81.
“ECONOMIC BELT OF THE SILK ROAD”: NEW OPPORTUNITIES AND PROSPECTS FOR MONGOLIA
Authors: Mavidkhaan Baasandulam
Published: March 2020

Earth is continents, seas, the developing countries, the developed countries, the centers and the borders is the One Belt-One Road initiative. On the other hand, the Sea “Silk Road” is called the “Economic Belt of the Silk Road” as a way of “New Belt and Road” for China's new long-term development strategy. "Silk Road" refers to the ancient land-based commercial trade route that originated in ancient China and connected to Asia, Africa and Europe.In order to benefit from the “Economic Belt of the Silk Road” initiative, China has partnered with other Asian countries and created two important financial development institutions, the Asian Infrastructure Investment Bank and the Silk Road Fund.The main objective of the initiative is to create an Eurasian trade economic integration space and cross-border transport corridors, that is, to strengthen the links between government policies and national development strategies along the route, promote international cooperation, and promote the development of joint ventures. For this purpose, the following tasks have been set: 1. Development of regional economic integration method; 2. Create an integrated transportation design for Asian transportation, connect communication networks, and develop pipeline systems; 3. Switch back to investment and trade barriers and create a good investment environment; 4.Strengthen national currency; 5.Deepening cooperation in the humanitarian field; 6.Expanding China's exports and domestic power growth will be concentrated in the western provinces (steel, lead, photovoltaic equipment, wind turbines).The “One Belt and One Road” is a new starting point for China-global relations and human development. Utilize the geographical advantages of Mongolia, China and Russia to increase cross-border trade between Mongolia, Russia and China, creating opportunities for logistics and transportation. China is one of the Mongolia's largest sources of foreign direct investment and is seen as a huge market for Mongolia to provide services and products.Mongolia hopes to unite its “Steppe Road” initiative with China’s “One Belt and One Road” initiative. The goal of the “Steppe Road” initiative aims to expand the Mongolian economy through cross-border transportation, strengthen the road line connecting Russia and China, transform and extend the current railway line in Mongolia, and build oil and gas between Russia and China. The pipeline improves the infrastructure of Mongolia. Mongolia and other Asian countries are actively participating in the “One Belt and One Road” initiative implemented in China to reduce risks and threats and gain new opportunities and advantages in regional cooperation.

The influence of the temperature and oxygen concentration in NS4 solution on the electrochemical characteristics of X70 steel for pipelines and the relationship of cathodic protection current density to limiting diffusion current density, in the normalized DSTU 4219 range of protective polarization potentials from -0.75 V to    -1.05 V (сh.s.е.) were investigated. It has been established that with increasing of the temperature from 20 to 80 °C, the corrosion activity of X70 steel increases, which is confirmed by more negative values of corrosion potential and an increasing of the corrosion rate, and indicates on the prevailing effect of temperature on the corrosion process compared to the effect of oxygen concentration. In the temperature range considered, the limiting diffusion current has a maximum value at 40 °C and decreases with increasing of temperature, correlating with a decreasing of the oxygen concentration. Under conditions of free oxygen access to the NS4 solution in the normalized DSTU 4219 range of protective polarization potentials, the ratio of cathodic protection to limiting diffusion  current varies from 0.4 to 1.3 at temperatures (20-40) oС, at temperatures (60-80) oC the ratio  is less than 1. Under conditions of limited oxygen access, the ratio  increases from 1.1 to 4.7. Using calculated and experimental results, it was shown that, at various values of relationship , conditions for excessive hydrogen evolution can be created, which represents a threat to the safe operation of the pipeline over time.  Data on the ratio values  should be taken into account when analyzing the protection state of pipelines.
Design improvement of preventer shear rams
Authors: Kopei B. V. , Myhailiuk V. V. , Okhrimenko S. O.
Published: March 2020

In case of an unexpected increase in the storm during drilling at sea or in other emergency cases, the drill or casing columns are cut off with cutters of pretensioners and sealed wells. The drill string remains in the well and it is kept by the pipe plugs of the pretensioners. Blind rams are fitted with a cutting blade, cutting pipes in the well, allowing blind rams to seal the well. The task was to improve the cross-cutting preventer rams to increase the efficiency of the drill pipe cutting. The proposed modernization of the cutter design makes it possible to cut the drill pipe completely. In her, as in the previous design, the cutting process is the same, but due to the shape of the cutting surfaces there is no pipe bending, but a complete cutting. However, the difference between these structures from foreign is that in the process of cutting the pipe first, its point deformation (puncture) occurs with a cutter. This, incontrast to other structures, reduces the load at the initial moment of the tube deformation on the hydraulic cylinders of the pre-filter, and therefore, the energy costs for this cutting process are reduced, and the load on other elements of the drive is reduced by the pre-plate layers.Key words: antiviral equipment, plate preventor, cut-off rams, pipe bending, finite-element analysis. To study the cutting process of a drill pipe, a three-dimensional model of the pipe itself and two dies were constructed. The three-dimensional model is created with simplified, since with the increase in the number of elements is complicated as the construction of a network of finite elements, and the calculation process itself continues for a very long time. The results obtained by the simulation model show the effectiveness of the cutting of the drill pipe and the possibility of complete closure of the pre-cutter with cross-sections.
Neo-liberalism and Institutionalism in the Short Life of TechBC
Authors: Hendrigan Holly
Published: March 2020

The Technical University of British Columbia (1999–2002) has received scant attention in the scholarly literature since it was folded into Simon Fraser University and became SFU’s Surrey branch campus. This article uses neo-liberal and institutional theory to understand the university’s economic mandate and the motivations of the staff and faculty who worked there. TechBC’s legislation and oral history interviews reveal neo-liberal influence in its purpose as an economic driver of the province, academic programs intended to satisfy the high-technology labour market, willingness to collaborate with industry, corporate governance structure, and reduced government funding support. TechBC employees were drawn to working at a start-up university, building an interdisciplinary curriculum, and employing new online teaching and learning methods. TechBC’s institutional logic of non-conformity and its aspirations to transform the university experience accounts for its community’s positive memories of the short-lived university.RésuméL’Université technique de Colombie-Britannique (1999-2002) a reçu peu d’attention dans la littérature académique depuis son incorporation à l’Université Simon Fraser où elle est devenue le Campus Surrey. Cet article utilise la théorie néolibérale et institutionnelle pour comprendre le mandat économique de l’université ainsi que les motivations du personnel et des professeurs qui y ont travaillé. Les statuts de TechBC et les entrevues en histoire orale révèlent une influence néolibérale dans sa mission comme moteur économique de la province, dans les programmes universitaires destinés à satisfaire le marché du travail de haute technologie, dans la volonté de collaborer avec l’industrie, ainsi que dans la structure de gouvernance corporative et le soutien financier limité du gouvernement. Les employés de TechBC ont été incités à travailler dans une nouvelle université, à développer un programme d’études interdisciplinaire et à utiliser de nouvelles méthodes d’enseignement et d’apprentissage en ligne.

What is the point of benchmarking e-government? An integrative and critical literature review on the phenomenon of benchmarking e-government
Authors: Skargren Fredric
Published: March 2020

This literature review looks at research conducted on the phenomenon of benchmarking e-government during the years 2003 to 2016 and entails 27 articles. The review shows how this field has changed over time, its main findings and what the potential benefits are for the public sector in using the results from benchmarks. The findings reveal how initial research created taxonomies of benchmarks and criticised them for being too focused on measuring online services. This research was followed by even more criticism on how benchmarks can have a negative impact on e-government policy and development. During the same time-period there is research giving methodological support on how to improve ways of benchmarking. Later research offer theoretically and conceptually informed critique of benchmark-studies. The review finds that there are mainly implicit assumptions about the potential benefits in using benchmarks for improving e-government. The article concludes by discussing the implications of the findings in terms of the lack of context and relevance in benchmarks for e-government in relationship to the nature of public administration and makes suggestions for ways forward.

Published: March 2020

OBJECTIVE:

To compare outcomes of hospitalized preterm infants following previable prelabour rupture of membranes (PPROM) at≤23 weeks of gestation.

METHODS:

Retrospective cohort study of preterm infants admitted for intensive care, between January 2006 and December 2016 following PPROM, was conducted. Short term clinical outcomes included severity of respiratory morbidity, length of hospital stay and mortality. Neurodevelopment in survivors was assessed using Bayley’s Scales of Infant Development (3rd edition) at 24 months corrected age.

RESULTS:

A total of 82 preterm infants were admitted following PPROM at < 23 weeks and were grouped as: Group 1 ( n = 28) with PPROM < 20 weeks and Group 2 ( n = 54) with PPROM between 20–22 + 6 weeks. Median latency following PPROM was significantly longer in Group 1 infants [69(Interquartile range (IQR): 43–74; Range (R): 25–100 vs. 29(IQR: 10–53; R: 2–72) days, p < 0.001]. Median gestation at delivery was 27.4 weeks (Group 1) vs. 25.1 weeks (Group 2). Group 1 had a significantly higher incidence of oligohydramnios [13(46.4%) vs. 8(14.8%), p = 0.002], lower Apgar scores (<7) at 5 minutes [19(67.9%) vs. 24(44.4%), p = 0.044], increased pulmonary hypoplasia [13(46.4%) vs. 5(9.3%), p < 0.001], joint contractures [3(10.7%) vs. 0, p = 0.037] and mortality [10(35.7%) vs. 7(13.0%), p = 0.016]. Neurodevelopmental outcomes at 24 months corrected age were comparable in the 36 surviving infants (9/18 vs. 27/547).

CONCLUSION:

Morbidity and mortality is high in infants born after previable PPROM; specifically, in those with PPROM < 20 weeks although early childhood neurodevelopmental outcomes were comparable. Larger prospective studies focussing on long term neonatal outcomes are needed to confirm these findings.
THE ANALYSIS OF PHYSICAL PROPERTIES OF THE ULTRA-WIDEBAND CHANNEL MODEL IN COMMUNICATION AT SHORT DISTANCES
Authors: Nguyen Nhan Chi , Duong Nghia Hoai , Dinh Anh Van
Published: March 2020

Accurately modeling the channel is extremely important for the design of communication systems. Knowledge of the key features of the channel provides the designers with the ability to predict performance of the system for specific modulation, channel coding, and signal processing. In this paper, we will present the analysis of physical properties of the UWB channel model and propose an UWB channel model for short distance wireless communications (with a comparison to the IEEE 802.15.3a channel model). Through the analysis and design, conclusions related to the UWB channel model were drawn as follows: there are reflection, diffraction, multipath transmission, and signal attenuation with distance and frequency but there is no pulse distortion.

Published: March 2020

From the total crude ethanol extract of Jasminum subtriplinerve Blume.’s leaves and stems, (Vang se in Vietnamese), four extracts were obtained by partitioning with petroleum ether, cloroform, ethyl acetate and n-butanol solvents. These four extracts were tested for antioxydative activity, determined using the DPPH●.radical scavenging and nitric oxyde-inhibitory assay. All the extracts showed antioxidative activity except the petroleum ether extracts. Among the crude extracts, the acetate ethyl extract was the most potent extract in both assays with the SC50 values of 8.2 μg/mL and 80.7 μg/mL, respectively. From the VS3 substract, three compounds were isolated, including two acids namely 3,4- dihidroxybenzoic acid (1), 3,4,5-trihidroxybenzoic acid (2) and a glycoside, verbascoside (3). The structure of those compounds was elucidated by spectrometric methods IR, MS, LC-MS, 1D-NMR, and 2D-NMR.
SYNTHESIS AND IMMUNOGENICITY TESTING OF A BIOINFORMATICSPREDICTED B-CELL EPITOPE ON THE HA ANTIGEN FROM INFLUENZA H5N1 VIRUS
Authors: Tran Kim Thi Hong , Tran Thuy Thi Nhu , Tran Thuoc Linh
Published: March 2020

In order to develop vaccine with stable efficiency against easily transforming virus such as influenza H5N1 virus, bioinformatic tools were used to predict conserved epitopes from viral antigens to be used as materials for the development of polyvalent vaccine against this virus. Using this approach, we have successfully predicted one B-cell continuous epitope consisting of 21 amino acids on conserved domains of HA antigen from H5N1 influenza A virus. To confirm the immunogenicity of this epitope, genetic manipulating techniques have been used to prepare the recombinant epitope in E. coli as a fusion form with H:1,2 flagellin antigen from Salmonella Typhimurium and with glutathione S-transferase. This recombinant antigen has been collected, purified and used for immunizing mice. Using ELISA method, we could successfully prove that the antirecombinant GST-H:1,2-HeBc antibodies could recognize and bind specifically to the HA antigen derived from an influenza H5N1 virus strain isolated from infected chickens in Vietnam in the same way as did the antiserum from mice immunized with commercial inactived H5N1 influenza vaccine.

REVIEW CARRYING CAPACITY OF VAM CO DONG RIVER OF LONG AN PROVINCE FOR MAKING AN EXHAUST WASTE MANAGEMENT LICENSING
Authors: Nguyen Lam Minh , Nguyen Phuoc Van , Lam Triet Minh
Published: March 2020

The paper presents some results on study of the carrying capacity of Vam Co Dong (VCð) river, section crosing Ben Luc district, Long An province. The MIKE 11 – hydrodynamic and water quality model was used in this study. Main pollutant sources from industry, agriculture, domestic and runoff in the areas were calculated for the simulation. Model results showed that the carrying capacity of the Vam Co Dong river from 2009 to 2015 and to 2020 is limited in dry season, while during the transition of rainny and dry season, the recieving capacity for BOD is about 10 tons/day and 15 tons/day for COD which is rather low. The recieving capacity is increased in rainny season with 75tons/days for BOD and 145 tons/day for COD. Especially, during flooding season (September and OcTober) the receiving capacity can raise up to 150 tons/day for BOD and 300 tons/day for COD. For others water quality parameters, the Vam Co Dong river can recieve certain loadings at some specific sections.Based on the calculated carrying capacity of Vam Co Dong river, we can determine which areas is allowed for wastewater discharge with limited pollution loadings so that the river will not be deteriorated in the future.

Designing tourism products for Dak Nong province in the perspectives of regional linkage
Authors: Thi Phuong Lan Ngo
Published: March 2020

The Central Highlands is a tourism region rich in natural tourism resources and unique cultural characteristics, forming Vietnam’s special tourist hubs such as Da Lat and Buon Ma Thuot. In addition to these key hubs, there is another locality with great potential for the resources that are capable of creating a new tourism space associated with the typical natural landscape and unique ethnic cultural values: Dak Nong Province. With the advantages of available resources and the geographical location with accessibility to Ho Chi Minh City and the vicinity of the Central Highlands and South Central regions, Dak Nong is eligible to develop into a new tourism destination, creating a counterbalance, stimulating production and diversifying tourism services for the Central Highlands in general and Vietnam in particular. Based on the results of field research in July 2018 and January 2019, the paper proposes directions for designing Dak Nong’s overall tourism products in the perspectives of regional linkage. The viewpoint of the paper is that building tourism products is essential for tourism development and must be oriented towards establishing regional links. Designing Dak Nong’s tourism products in the perspectives of regional linkage needs to be based on the competitive advantages of each locality’s advantages. Unlike economic regional links in which the state plays an important role, the key role in these tourism value chains must be played by tourism enterprises; the State plays a leading role in creating an environment for these chains to work.

Published: March 2020

Chemical composition and nutritive parameters of maize stover (Zea mays) fractions and cassava (Manihort esculanta) foliage for sustainable ruminant production was studied. Cassava foliage and fractions of maize stover (stem and leaf) were gathered and oven dried for proximate composition, fibre fractions and nutritive parameters (Dry matter intake (DMI), Digestible dry matter (DDM) and Relative feed value (RFV) were calculated. The experimental design was a completely randomized design (CRD). Results shows a significant difference (P<0.05) in the all the parameters considered for the proximate composition across the experimental treatments. The contents ranged from 85.21 – 88.77% for dry matter (DM), 6.27 – 19.72%, 1.89 – 3.78%, 14.89 – 17.08%, 51.88 – 62.47%, 3.27 – 11.23% and 36.90 – 56.70% for crude protein (CP), ether extract (EE), crude fibre (CF), neutral detergent fibre (NDF), ash and non-fibre carbohydrate (NFE), respectively. Cassava foliage had highest (P<0.05) contents of fibre fractions considered. The acid detergent fiber (ADF), acid detergent lignin (ADL), cellulose (CEL) and hemicellulose (HEM) were 59.18%, 18.36%, 26.50% and 27.10%, respectively for CSL. There was a significant different (P<0.05) in the phytochemical contents across the experimental materials. Similar (P>0.05) value was recorded for DMI, DDM and RFV. Conclusively, the experimental treatments exhibited nutritional qualities that made them a feed resources for ruminant production. Cassava foliage had better proximate composition and fibre fractions, therefore it is recommended for the farmers.
Marriage and Divorce: How the Two Manifest within the Banjarise Community in Indonesia
Authors: Umar Masyithah
Published: March 2020

Currently, divorce rate in most big cities of Indonesia display an alarming trajectory that warrants close examination of the factors leading to it. With Islamic religious courts presiding over most of the divorce cases, which account for the largest portion of all legal cases in the country, this study examines the causal factors of divorce particularly in Bajarmasin city in South Kalimantan province. The study uses a qualitative research method. Data was collected through interviews, observations, and documentation study techniques. Findings indicate that there is little and sometimes no public awareness and understanding of the legal procedure of settling marriage deputes as many skip other available services like the Marriage and Divorce Advisory Board and directly seek divorce rulings from religious courts. It has also been established that domestic violence, secret marriages (Siri), early marriages and infidelity among other factors, are the main causes of the divorce. It has been established most of the couples seeking divorce ignore or are either ignorant about the roles and existence of the Marriage and Divorce Advisory Board which is formality tasked with the role counseling marriages couples with varying disputes and grievances. It is concluded that public awareness of proper channels and procedures of settling marriage disputes, women empowerment, increasing and promoting girl child education, strengthening family incomes, legal counseling on marriage law and a brief orientation on the dangers / impacts of secretary and early marriages could in the long-run curb the rampant divorce rates in the country and of course in Banjarmasin.
Building as a Verb
Authors: Ammendola Jacopo
Published: March 2020

This paper describes the approach of architecture/urbanism practice and research workshop “orizzontale”, based in Rome, Italy.
The approach of the group is heuristic: it is to get involved, to put themselves on the line, to “play the game”. As a machine that absorbs and transforms every kind of things, orizzontale has a clear attitude for mutation over production. The act of building things is a primary tool the group uses to build communities, link them together and create confidence in the idea of a better society.
Experimental does not mean “avant-garde” but rather “empirical, exploratory, in-progress”. The scientific attitude toward fact-finding and result-testing is an integral part of orizzontale approach, together with the artistic aspects of the work. Among the strategies adopted by the collective a special attention should be given to the attempts to translate in a spatial language the ideas, very literally. The results of this process can be called “spatial metaphors”, “discursive buildings” or “talking machines”. What orizzontale leaves behind is not necessarily a construction, but the process which is able to build up knowledge, consciousness, and trust.
The Test: “how will we know what it is that we are doing?”
Authors: Cittadini Benjamin , Peade Craig
Published: March 2020

The Test outlines a public art project developed by ROARAWAR FEARTATA titled The Crossing, undertaken as part of Melbourne City Council’s 2019 Test Sites program. Drawing on the figure of the ferryman from Hermann Hesse’s Siddhartha, as well Henri Lefebvre’s concept of Rhythmanalysis, this project sought to occupy the everyday practice of the pedestrian crossing, utilising the position of the artist within this everyday practice to develop a methodology for conducting a rhythmanalysis of public space. Through the process of performative adventure and the reading of rhythms, the project aimed to strategise a process for art to participate in the practice of the everyday whilst maintaining the tension of the question: “how will we know what it is that we are doing?”

Authors: Nekhamin M.M. , Bondzyk D.L.
Published: March 2020

The existing difference in the models used to describe the burning rate of solid fuel particles, and, accordingly, the difference in the constants appearing in them, determines the relevance of the formulation of the relation between the constants known from the literature and the parameters that must be set in programs for CFD modeling of heat and power processes. This, in particular, relates to modeling the combustion of solid fuels in the well-known program ANSYS FLUENT. The paper outlines a possible approach to solving this problem. Bibl. 5, Fig. 3.

Published: March 2020

Background: The course of hepatitis B virus (HBV) infection is not only determined by variations in viral virulence but may be influenced by host immune response, where Human Leukocyte Antigen (HLA) plays an important role.

Objective: The purpose of the present study was to explore whether HLA-DRB13* allele of MHC gene had any influence in spontaneous recovery from HBV infection among Bangladeshi adults.

Method: This cross sectional study was carried out at the Department of Virology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka Bangladesh. A total of 90 randomly selected hepatitis B virus infected adult patients, consisting of 30 acute HBV infections, 30 chronic HBV infection and 30 healthy controls were selected according to selection criteria for evaluation of HLA DRB1*13 allele. Detection of HLA DRB1*13 allele was done by conventional PCR followed by agarose gel electrophoresis.

Result: The study revealed a significant increase of DRB1*13 in acute hepatitis B (AHB vs HC-40% vs 6.7%, RR= 9.4; P value <0.05, AHB vs CHB=40% vs 10%; RR=2.27, P value <0.05) compared to chronic hepatitis B infected (HBV) patients and healthy controls (CHB vs HC-10% vs 6.7%, RR= 1.5, P>0.05). This is the first report on HLA DRB1* gene associations among hepatitis B (HBV) infected Bangladeshi patients.

Conclusion: The present study revealed that HLA DRB1*13 was associated with protection against persistent HBV infection among acutely infected adult HBV patients in Bangladesh.

Authors: Akram Arifa , Akram Lubana
Published: March 2020

Hand, foot & mouth disease (HFMD) is a contagious and emerging infectious disease caused by picorna viridae family. It was first reported in New Zealand in 1957 is caused by Coxsackie virus A16 (CVA16), human enterovirus 71 (HEV71) and occasionally by Coxsackie virus A6 and Coxsackie virus A10, are also associated with HFMD and herpangina. Though only small scale outbreaks have been reported from United States, Europe, Australia Japan and Brazil for the first few decades, since 1997 the disease has noticeably changed its character as noted in different Southeast Asian countries. In recent years Bangladesh also faces some cases of HFMD. Though HFMD is a mild disease but in rare cases may develop neurological complications. Early detection and good clinical assessment can prevent the fatal progression and also can reduce morbidity and mortality regarding HFMD.

Authors: Islam ABMS , Khan ZH , Mazumder AR
Published: March 2020

Twenty two soil samples from four pedons representing some established soil series namely Jaonia, Haiti, Taras and Digli from the Chalan beel area of Bangladesh were studied in the field as well as in the laboratory for their pedogenesis and characterization. All the soils are heavy textured with clay contents ranging from 47 to 60 percent. The soils are moderately acidic to neutral in reaction with high base saturation. The soils have developed redoximorphic features including redox concentration and redox depletion due to periodic flooding more than 4 months in the monsoon season. Development of cambic horizon in these soils is the most notable morphogenetic feature. Gleization and weak hydromorphism are the dominant pedogenic processes. At the subgroup level the soiis were classified as Typic Endoaquepts and Aerie Endoaquepts. Finally the soiis are characterized at the family level of soil taxonomy.

Authors: Hosain Md Eilious , Naser M Niamul
Published: March 2020

In the present investigation, zooperiphyton communities comprised protozoa, rotifera copepoda, cladocera, ostracoda, conchostraca, insect’s larvae, oligochaeta, nematoda and mollusca. The group of zooperiphyton on three substrates showed no significant differences (P>0.05). Rotifers and protozoans were the most dominant group of total zooperiphyton abundance among three substrates. The interrelationships between zooperiphyton groups and physicochemical features of water as well as among different groups of zooperiphyton revealed that abundance and growth of zooperiphyton on substrates are influenced by water quality parameters and each with others. The ranges of physicochemical features of water of Dhanmondi lake were suitable for zooperiphyton communities including aquatic biota and also play a significant role to settle zooperiphyton on three substrates. That can help in enhancing productivity of the lake as well as sustaining aesthetic value of aquatic system.
