Published: November 2022

Organophosphate compounds are chemicals containing central phosphate molecules with alkyl or aromatic substituent’s. They occur in diverse forms and are used as pesticides, herbicides, nerve agents, etc. Organophosphate compounds are frequently used as pesticides in agrarian communities all across the world. South Asian countries such as Nepal use vast quantities of Organophosphate compounds for pest control in agriculture. Therefore, accidental and suicidal ingestion of Organophosphate compound poisoning has been common especially among the agricultural rural communities. Apart from muscarinic, nicotinic and central nervous system effects in rare instances, Organophosphate compounds are known to cause pancreatitis. Although pancreatitis is a rare complication of Organophosphate poisoning, it is necessary to evaluate patients with Organophosphate poisoning with serum lipase level, Ultrasound abdomen, and Contrast- Enhanced Computed Tomography(CECT) abdomen in patients with pain abdomen for early detection and management of acute pancreatitis.

Published: November 2022

Uremic stomatitis is a rarely reported oral mucosal disorder associated with renal disorder. It is mostly seen in cases of end stage renal disease or undiagnosed or untreated chronic renal failure. Its frequency has diminished due to the advent of renal dialysis. Clinically uremic stomatitis is characterised by the presence of painful plaques and crusts that are usually distributed on the buccal and labial mucosa, dorsal or ventral surface of the tongue, gingiva and the floor of the mouth. Ultimate treatment consists of improvement of blood urea concentration and underlying renal failure is supported by enhancement of oral hygiene with antiseptic mouthwashes and antimicrobial/ antifungal agents, if necessary. Here we report a case of a 50-year-old Male patient who reported to the department with the complaint of inability to open mouth due to ulcers present intra- orally, who was a kidney patient undergoing dialysis, who was then treated with topical steroid and antifungal medications with follow up made once in a week.

Authors: Iqbal Younas , Wang Chao , Wang Jianli , Li Lanwei , Li Shuyao , Chen Yanqun
Published: November 2022

In this work the thermoelectric performance of MgAgSb was improved by enhancing electrical conductivity, Seebeck coefficient and reducing thermal conductivity simultaneously. We synthesized MgAgSb at various sintering temperatures and researched its thermoelectric properties in detail. The effect of impurities associated with MgAgSb on the thermoelectric properties shows that their presence can deteriorate the performance. The resultant samples were tested after 2, 3 and 8 months from its preparation for thermoelectric performance and a significant enhancement in thermoelectric properties are observed. The resultant power factor improved from 8.5 μWcm-1K-2to 15.8 μWcm-1K-2 and the thermal conductivity is reduced from 1.12 Wm-1K-1 to 0.86Wm-1K-1 and we find an improved ZT~0.91. The internal mechanism for the reducing thermal conductivity is presented which plays an important role in improving ZT value of MgAgSb.Furthermore, we discussed that the strength of the chemical bonding among the atoms may also be reduced with the passage of time in thermoelectric materials and resulting in decrease in localized frequency of vibration, which has an ultimate effect in reducing the thermal conductivity of the material.

Authors: Adam Mujahed Nooraldaem Mirghani
Published: November 2022

Angioimmunoblastic T-cell lymphoma is a malignancy of mature T-cells. A 45 years old Sudanese female with generalized lymphadenomegalyreferred from Tayba hospital to Al-tayseer reference medical cent in histopathology and cytology laboratory department (Sudan) for her lymph node histopathology analysis. A surgical lymph node biopsy for histopathology analysis stained by H&E was performed and sections showed effacement of normal architecture of lymph node with disappearance of follicles and germinal center composed of polymorphic infiltrate of small tumour cells and large tumour cells. The small tumour cells showed irregular nuclei and clear cytoplasm. In this case report, we state that the delay of diagnosis was mainly a consequence of an insufficient clinical history, which led to an incomplete histological analysis, delay of reporting and need for second opinions for interpretation. We also strongly recommend that to obtain an accurate and precise diagnosis for AITL, PAS stain should be performed firstly to recognize the capillary invasion which facilitate the early diagnosis.

Fakta di lapangan menunjukkan belum ada suatu alat fungsional yang khusus digunakan untuk phlebotomyst melakukan pengambilan darah vena secara efektif dan efisien. Alat yang biasa digunakan oleh phlebotomyst dapat berupa benda-benda apa saja yang difungsikan untuk meluruskan tangan pasien dan terkadang menggunakan benda-benda seadanya yang dapat menimbulkan ketidaknyamanan, kecemasan, menyebabkan terjadinya hematom dan media untuk menularkan penyakit serta kualitas dari sampel yang kurang baik. Tujuan dari penlitian ini adalah untuk membuat suatu alat yang dapat digunakan untuk memberikan kenyamanan pada pasien, serta mengurangi risiko terjadinya hematom (pecahnya pembuluh darah) saat dilakukan tindakan venepuncture. Pada penelitian ini, kursi phlebotomy berbasis IoT telah berhasil dibuat menggunakan Node MCU tsp 8266 serta linier actuator hidrolik. Bagian lengan pada kursi tersebut diberikan bantalan yang lembut serta dapat diatur ketingggiannya sesuai dengan kenyamanan tangan pasien. Pengaturan ketinggian dapat dilakukan secara otomatis menggunakan smartphone. Dengan adanya alat ini diharapkan pengambilan sampel darah pasien lebih efisen, efektif, serta memenuhi syarat dan standar, sehingga pasien merasa puas terhadap pelayanan laboratorium yang diberikan.

Authors: Oliveira Mariana Corrêa Pitanga de
Published: November 2022

Este livro nos apresenta uma abordagem singular sobre as aplicações educacionais da linguagem da computação, compreendida não como suporte a algoritmos da engenharia, mas como instrumento de expressão e ferramenta semiótica. Sua utilização no campo da Educação Especial, tal como na pesquisa aqui apresentada, rompe barreiras culturais quanto ao desenvolvimento da pessoa com deficiência intelectual, abrindo campo para inúmeras investigações acerca do objeto e do sentido da experiência de aprendizagem. Com a expressão “imaginar e criar”, Mariana Pitanga sintetiza a verdadeira essência da linguagem de computação, que, transbordando o universo da lógica formal, institui-se como a essência do sujeito matemático, o Homem da Razão no mundo e para o mundo. Temos aqui uma contribuição da Educação Especial para o campo geral do ensino-aprendizagem. Luiz Antonio Gomes Senna Universidade do Estado do Rio de Janeiro
Self-regulating platforms?

Published: November 2022

The deadline for the transposition of Directive (EU) 2019/790 (the CDSM Directive) into national law expired on 7 June 2021. Some EU Member States have failed to perform the transposition, and so they also failed to introduce the new obligations under Article 17 prescribing brand new requirements that online content-sharing service providers (OCSSPs) shall comply with. As a part of these rules, OCSSPs shall amend their end-user licence agreements (EULAs) to include terms on the enforcement of the mandatory limitations and exceptions (quotation, criticism, review, as well as use for the purpose of caricature, parody and pastiche) under Article 17(7) and the establishment of an effective complaints and redress mechanism regarding the removal of the user-generated content in line with Article 17(9). In the second phase of our ongoing EU-funded research project, we examined the extent to which specific OCSSPs have amended their EULAs to meet these EU obligations. Our empirical data show that, besides only little progress, new sources of conflict have emerged.

Published: November 2022

Chilaiditi’s sign is a rare radiological finding in which a portion of the colon or small intestine is interposed between the liver and right hemidiaphragm. Associated to pain, it is called Chilaiditi syndrome. We describe the case of a patient who was admitted to our radiology department to release a body-computed tomography (CT) for its breast cancer extension assessment. We incidentally discovered a colic hepato-phrenic interposition related to a Chilaiditi sign associated with right renal agenesis. In this case report we treated Chilaiditi sign can exist without Chilaiditi syndrome, as it could be associated with other pathologies and abnormal anatomic malformation like renal agenesis.
Reality televizija: Ogledalo stvarnosti ili iluzija u svijetu spektakla?
Authors: Hrnjić Kuduzović Zarfa
Published: November 2022

Development of the reality programmes was originally conceived as an entertaining and documentary concept although now the spectacularising of banalities ''corrodes'' its educational potential, transforming it into an advertainment and the voyeuristic spectator into a passive homo videns. Nevertheless, this hybrid genre revived optimistic prediction about implementing democratic potential of television by focusing on the common man.
AN EVALUATION OF ONLINE ARCHITECTUREAL DESIGN STUDIOS: STRENGHT AND WEAKNESSES OF ARCHITECTURAL EDUCATION IN BANGLADESH DURING COVID 19
Authors: Faruk Mohammad , Binte Alam Shayeeka
Published: November 2022

Bangladesh, like many more countries around the world came to a halt with the start of COVID-19 pandemic. In order to manage the collapsed education system, different institutions started trying various alternative virtual mediums to reach out scattered students country wide. These included the use of television telecast, radio and communicative platforms like Zoom, Google meet, Google classroom, Facebook and many more. Unlike most subjects, Architectural teaching requires to adapt to a studio-based teaching approach with ‘one to one interaction’ and plenty of ‘on paper drawing exercises’ involving the students and their instructor. The literature review conducted within the scope of this research could not find many studies trying to identify the challenges faced by various architecture schools across the world, although there are studies on education in general during pandemic. The Department of Architecture at BRAC University is one of the leading architecture schools in Bangladesh. The department has developed a new online teaching learning platform named BuX to continue with its online academic program during Covid 19 pandemic. This paper reports the preliminary findings of a larger research conducted at the department. It aims to evaluate the newly adopted virtual teaching platform for its acceptability among the stakeholder; i.e., the students. The objective of the study was also to assess the adoption rate of virtual classes and to determine the various benefits, challenges, and reasons for non - adoption by the stakeholders. The research takes a mixed method approach supported by extensive literature review and online survey using Google form. Approximately 25% students of the department participated in the survey. This study can be extended further in collaboration with other architecture schools both in Bangladesh and abroad. This may help the university policymakers and the academics to evaluate the pedagogical strategies for architectural education implemented during the pandemic. Furthermore, it will also help to identify the scopes for developing an appropriate online teaching and learning method for the ‘new normal’ situations. Keywords: Architectural Education, Architectural Pedagogy, Bangladesh, BRAC University, Virtual Class.
APPLYING ACTION RESEARCH TO STRUCTURE INTERACTIVE AND ENGAGING DESIGN STUDIOS IN ARCHITECTURE SCHOOLS: A CASE STUDY OF UNIVERSITY OF BAHRAIN
Authors: Agha Shah Ayesha
Published: November 2022

Architecture design studio is a social environment where interactions among students and a teachers serve as a pedagogical tool to enhance the students’ imaginative and creative thinking. However, keeping students motivated for long hour studios is a challenging task. This Action Research (AR) is conducted to evaluate the effects of “structuring” the teaching sessions that take place in the architecture design studios to observe their effects on the motivational level of the students while working for prolonged length of time in a studio. The study examines two types of structured studios: semi-structured studios and fully-structured studios through a meticulous review of the planning, implementation and the cycle of activities. The findings reveal that a higher level of motivation is observed in students when the studio structure is designed to encourage collaborative learning amongst the students, and when the teacher acts as an active facilitator in the studio instead of being a mere observer.

Published: November 2022

The considerable increase in the leachate infiltration rate through the Oulad Berja landfill as well as agricultural activities in the Mnasra region have a detrimental effect on the quality of groundwater. The percolation of leachate through the unsaturated zone of the soil, towards the water table, could have serious consequences on the quality of water and the environment in general. Groundwater is the only source of drinking water supply for the rural population of the Mnasra zone. As part of the assessment of the water quality of wells in the Mnasra region, we analyzed 30 water samples taken from different wells during the year 2019-2020. The analyzes were carried out in the "ONEP" laboratories The comparison of the results obtained with the WHO standards revealed a high level of pollution compared to the recommended standards.  These results made it possible to classify these waters in the bad to very bad category.

Background- Lichen Planus (LP) is a subacute or chronic inflammatory, autoimmune and papulosquamous disorder affecting the skin, oral mucosa, genital mucosa, scalp, and nails. Although the etiology and pathogenesis are not fully understood, it is thought that Lichen Planus represents a T cell-mediated inflammatory disorder. Objectives- To describe the various morphological types of Lichen Planus and to estimate the metabolic derangements in Lichen Planus. Methods- It was a Case-control study conducted at rural tertiary care hospital for 18 months from January 2020 to June 2021 conducted in Patients attending the Department of DVL. Purposive sampling method was used. Sample size was calculated based on the Mysore study conducted by Singla R[1] et al, where the dyslipidemia was reported as 65% among cases. However, it was considered to take ‘120’ cases and ‘120’ in 1:1 ratio. So, the total sample size for this study will be ‘240’. The data was entered into MS excel 2007 version and further analyzed using SPSS version 21. Descriptive statistics was done for categorical data and was analyzed using percentages and the continuous data was analysed using mean and standard deviation.
A STUDY OF THE EFFECTS OF CLIMATIC FACTORS ON TREE SAPFOLW IN AN AGROSILVOPASTORAL SYSTEM
Authors: Rakkibu Md. Golam
Published: November 2022

Effects of climatic factors such as solar radiation, air temperature and relative humidity on the rate of tree sapflow were studied in a agrosilvopastoral system of agroforestry using the Thermal Dissipation Probe (TDP). Sapflow was found to be positively correlated with solar radiation and air temperature and negatively correlated with relative humidity. Sapflow revealed to be closely dependent on air temperature, solar radiation and related humidity at high stem densities (2500 stems/ha.) and less correlated at low stem densities (400 stems/ha.).
SALINE WATER INGRESSION IN UPPER PART OF BALESWAR RIVER NEAR NAZIRPUR UNDER PIROJPUR DISTRICT: A CASE STUDY
Authors: Bhuiyan M.R. , Ahsan M. , Aziz A. , Begum S.
Published: November 2022

A five year project was undertaken to address the salinity problem in the upstream of Baleswar river. The information generated during this period have been presented in this paper. Previously the Madhumati-Baleswar river system was completely non saline throughout the year. Recently upstream fresh water flow from the Madhumati river through the Baleswar river passing in between Chitalmari and Nazirpur Upazila is about to cease due to prolonged siltation on the river bed. During intensive monitoring work (1995-1999) some canals such as the Chitra river, Vasa canal, Santoshpur canal, Lara canal etc. are identified as the portals of saline water in the upstream of the Baleswar river in dry season. Due to tidal effect they carried saline water from Daratana river to Baleswar river. As a result high water salinity prevailed in Baleswar river in between February and May. Maximum water salinity ECw 17.6 dS/m and soil salinity ECe 4.4 dS/m were recorded in May. Water extraction for irrigation in the riparian area was restricted due to high salinity. To minimize this salinity problem upstream fresh water flow from the Madhumati river to the Baleswar river has to be increased. Increased volume of upstream fresh water flow will push saline water back to downward direction. The major portals namely Chitra river and Vasa canal may be closed seasonally by constructing sluice gate with proper engineering design to prevent entry of saline water in the Baleswar river.

A COMPARATIVE ANALYSIS OF THE BUDGETS OF BANGLADESH DURING THE DECADE OF NINETIES
Authors: Ahmed S. N. , Hamid F.
Published: November 2022

An attempt was carried out for comparative analysis of the national budgets of Bangladesh formulated during the decade of nineties. Consequently, the study not only compares the budgetary functions, objectives and attainments of the Jatiyo Party (JP), the Bangladesh Nationalist Party (BNP) and the Awami League (AL) governments but also compares the economic position of the country under dictatorship with that under democracy. Aspects like setting of specific targets in the fields of revenue earnings, foreign grants, foreign loan, annual development programme etc. and attainment of set goals, collection of tax and non-tax revenue, expenditure pattern of the successive governments have been covered in the present discussion. The paper makes it clear that though there are significant differences in the political ideology of the three main political parties they share same policy prescriptions in the field of economics. The only significant difference that lies between dictatorship and democratic rule is that the former regime is characterized by heavy dependence on foreign funds whereas the latter regime made the scenario up side down. Concerning the democratic rule the conclusion is that whether the highlighted period is a story of success or failure, credit or discredit for that goes to both the BNP and the AL.
