The Importance and Reality of having an Ombudsman in Bangladesh
Authors: Abdul Hannan Mohammad
Published: December 2022

The fundamental aim of a country like Bangladeshis to realise through the democratic process a socialist society, free from exploitation- society in which the rule of law, fundamental human rights and freedom, equality and justice, political, economic and social will be secured for all citizens. The Office of an Ombudsman is not a basic institution of a democratic government; but it is very important to keep democracy intact and effective. Article 77 of the Constitution of Bangladesh is inserted therein in conformity with this statement of the Preamble to attain the same purpose.

Authors: Fernandez Pacella Lionel , Di Pasquo Mercedes
Published: December 2022

Background and aims: Taxonomic works of the modern pollen grains from the vegetation of the Iberá Wetlands from northeastern Argentina, and other areas of the Corrientes province, have mostly been carried out in last decade. However, very few of these taxonomic works include illustration of palynomorphs. The objective of this contribution is to provide the first morphological records of palynomorphs of angiosperms, ferns, lycophytes and bryophytes from sediments from the Holocene of the Iberá Wetlands.
M&M: Core samples obtained by mean of a Livingston-type sampler from six lakes in their central and deepest parts on the western margin of the Iberá Wetlands were analyzed.
Results: Fifty-five types of palynomorphs are described and illustrated: 46 pollen types correspond to 27 families of angiosperms and nine trilete spore-types to ferns, lycophytes and bryophytes. Information to differentiate local (species that form part of the natural vegetation of the Iberá Wetlands) and extra-local taxa (those that do not belong to the Iberá), that achieved to depocenters mostly by means of wind currents coming from farther regional vegetation, was included.
Conclusions: Pollen grains and spores identifications up to species level enhances paleoenvironmental reconstructions based on more accurate ecologic information and geographical distribution. This work broadens the knowledge of the palynological flora of northeastern Argentina and it will contribute to differentiate the local vegetation from the extra-local in future paleocological and paleoenvironmental interpretations.

Published: December 2022

Background: Ischemia and reperfusion injury in the brain triggers cognitive impairment which are accompanied by neuronal death, loss of myelin sheath and decline in neurotransmission. In this study, we investigated whether therapeutic administration of Brain Factor-7® (BF-7®; a silk peptide) in ischemic gerbils which were developed by transient (five minutes) ischemia and reperfusion in the forebrain (tFI/R) improved cognitive impairment. Methods: Short-term memory and spatial memory functions were assessed by passive avoidance test and Barnes maze test, respectively. To examine neuronal change in the hippocampus, cresyl violet staining, immunohistochemistry for neuronal nuclei and fluoro Jade B histofluorescence were performed. We carried out immunohistochemistry for myelin basic protein (a marker for myelin) and receptor interacting protein (a marker for oligodendrocytes). Furthermore, immunohistochemistry for vesicular acetylcholine transporter (as a cholinergic transporter) and vesicular glutamate transporter 1 (as a glutamatergic synapse) was done. Results: Administration of BF-7® significantly improved tFI/R-induced cognitive impairment. tFI/R-induced neuronal death was found in the Cornu Ammonis 1 (CA1) subfield of the hippocampus from five days after tFI/R. Treatment with BF-7® following tFI/R did not restore the death (loss) of CA1 neurons following tFI/R. However, BF-7® treatment to the ischemic gerbils significantly improved remyelination and proliferation of oligodendrocytes in the hippocampus with ischemic injury. Treatment with BF-7® to the ischemic gerbils significantly restored vesicular acetylcholine transporter-immunoreactive and vesicular glutamate transporter 1-immunoreactive structures in the hippocampus with ischemic injury. Conclusions: Based on these results, we suggest that BF-7® can be utilized for improving cognitive impairments induced by ischemic injury as an additive for health/functional foods and/or medicines.

Meta-analytic evidence suggests no correlation between sleep spindles and memory
Authors: Ujma Péter Przemyslaw
Published: December 2022

In a recent meta-analysis currently available as a preprint, Kumral et al summarize 1427 effect sizes from 53 studies about the association between sleep spindles and memory-related outcomes. This is a state of the art collection of the literature. The authors write that sleep spindle characteristics are related to various measures of memory, and that their findings suggest that „sleep spindles are involved in learning and plasticity, thereby representing a general physiological mechanism for memory consolidation”. They detect substantial publication bias in the literature, but fail to control for it. In this commentary I show that once publication bias is accounted for, there is no relationship between sleep spindles and memory, and thus it is unlikely that sleep spindles are indeed generally implicated in learning and plasticity.

Published: December 2022

The condition of Indonesian students' critical thinking skills is ranked 6th lowest with an average score of 379 on PISA 2018. The lack of students' critical thinking skills is found in learning that is still one-way using conventional models. This makes students less enthusiastic about listening and understanding the material presented. These conditions can be trained by applying exploratory learning so that students can find and understand, and solve problems. One learning model that can foster critical thinking skills in students is the discovery learning model which can support students to be maximally involved in identifying and organizing the way students learn to discover knowledge concepts. This study aimed to determine the effect of the discovery learning model on students' critical thinking skills using the Systematic Literature Review method according to the exclusion criteria and found 12 articles obtained through Google Scholar. The results of the meta-analysis show that the discovery learning model influences students' critical thinking skills at every level of education. The discovery learning model has the highest effect on elementary education level flat material with an effect size of 1.9. The junior high school level shows the highest effect size of 2.1 with social arithmetic material. The SMA/SMK level gives the highest effect of 1.18 in statistics. It can be concluded that the discovery learning model influences critical thinking skills in mathematics.

Об'ємні числа, в алгебрі та математичному аналізі дають можливість забезпечити конкретну інтерпретацію складних та суперечливих явищ чи об'єктів навколишнього світу, які характеризуються двоїстими властивостями. Конкретна інтерпретація обумовлена властивостями просторово невизначеної одиниці, яка забезпечує виконання всіх операцій алгебри із об'ємними числами, а також властивістю їх взаємозворотного дзеркального відображення. Відповідно, дослідження властивостей об'ємних чисел представляє істотний інтерес при використанні в математичному моделюванні різних процесів.

Тому питання дослідження властивостей об'ємних чисел, як і їх комбінації у вигляді суми коефіцієнтів на відповідних сферах є одним з основоположних.

Завдяки проведеним розрахункам встановлено гармонійний закон зміни суми дійсних коефіцієнтів об'ємних чисел, залежно від їх знаходження на довільній сфері, згідно з яким відношення довжин хвиль по паралелях дорівнює відношенню відповідних амплітуд, а відношення довжини хвилі до амплітуди, для довільної широти, є величина постійна. А також встановлена межа переходу від позитивного максимального значення суми в першій октанті до мінімального негативного в сьомій октанті. Об'ємне число першої октанти, сума дійсних коефіцієнтів якого є максимальною за умови рівності чисельних значень цих коефіцієнтів, є геометричним центром сферичного трикутника відповідної октанти. Дзеркальне відображення даного числа на відповідних октантах числового простору визначає геометричний центр сферичних трикутників.

Дані властивості об'ємних чисел можуть бути використані для математичного моделювання як фізико-математичних аспектів світу, так і різних еволюційних, біохімічних, технічних та інших процесів.

Сучасні умови експлуатації деталей машин, агрегатів, обладнання, інструмента та механізмів висувають підвищені вимоги до їх фізико-механічних характеристик та робочого ресурсу. У зв’язку з цим велике значення мають властивості їх поверхневого шару та набуває актуальність розробка нових технологій зміцнення деталей з конструкційних матеріалів. Для обробки виробів з вуглецевих та легованих сталей широко застосовують методи створення різноманітних функціональних покриттів. Покриття — локально змінений поверхневий шар, що характеризується певним хімічним та структурно-фазовим складом, який якісно відрізняється від матеріалу основи. Метою роботи є пошук раціональних композиційних порошкових середовищ, що дозволяє сформувати зносостійкі захисні шари на конструкційних матеріалах з різним вмістом вуглецю з використанням технологічних процесів ЕСД В якості оптимізуючого фактору прийнято поверхневу твердість, що прямопропорційно впливає на зносостійкість в умовах різних видів тертя. Вирішення цієї задачі дозволяє забезпечити довговічність обладнання в умовах коксохімічного виробництва та деталях комунального підприємства «Водоканал».

У результаті регресійного аналізу отримуються рівняння, що показують залежність зносостійкості захисних покриттів від режиму теплового самозаймання та вмісту легуючих елементів. У результаті розрахунків отримуються наступні рівняння: Y1 = 87,6 – 1,3Х1 – 1,3Х2 – 0,6 Х3 – 1,5 Х12 + 1,5Х22 + 3Х32 – 0,875Х1Х2 + 2,125Х1Х3 – 0,25Х2Х3. Перевірка адекватності моделей показує, що їх можна використовувати для прогнозування функцій відгуку при будь-яких значеннях факторів, що перебувають між верхнім і нижнім рівнями. За допомогою математичного планування експерименту значно зменшується кількість досліджень необхідних для розрахунку коефіцієнтів рівняння регресії та отримання адекватної моделі, яка характеризує вплив елементів КПС на експлуатаційні властивості сталей з легованими захисними покриттями. Поверхні відгуку отриманих математичних моделей представлено тривимірною графічною залежністю.

За результатами досліджень, виявлено, що у порівнянні з покриттями отриманими в ізотермічних умовах мікротвердість сталі 45 з покриттями отриманими в КПС вища в 1,8—2,0 рази.

Digital transparency and political communication
Authors: Campos-Domínguez Eva , Díez-Garrido María
Published: December 2022

The academic debate on transparency has experienced a boom in recent decades. A review of the scientific literature allows us to identify two key moments in the discussion on digital transparency: the declaration of Barack Obama’s Memorandum on transparency and open government in 2009 and the Cambridge Analytica scandal in 2018. The first was linked to a groundswell of enthusiasm for the concept of government transparency, with the promise that it would boost accountability, eliminate corruption, and promote political efficiency in a crisis of institutional legitimacy. The second altered the digital transparency agenda and catalysed a discussion about the need for technology and social media companies (Facebook, Twitter, or Google) to make transparency commitments because of their role in generating a public conversation and the democratic implications. This paper reviews the idea of digital transparency in the scientific literature framed in the field of political communication and tries to reflect the need for more research on its political, social, and cultural implications.

Published: December 2022

Akdeniz fitocoğrafik bölgesi içindeki Ege Bölgesinde iklimi, yeryüzü özellikleri ve farklı yükseltilere sahip olması sebebiyle tür çeşitliliği oldukça zengindir ve bu bitkiler insanlar tarafından kullanılmaktadır. Bu çalışmada, bölgedeki etnobotanik ve geleneksel bitki kullanımı kapsamındaki yayınlardan ağaçların geleneksel adlarının geçtiği 47 yayın değerlendirilmiştir. Ege Bölgesi geleneksel kullanımı olan 96 ağaç taksonuna ait 390 adet yöresel ad verildiği tespit edilmiştir. Bu sayılar bölgede ağaç türlerinin iyi tanındığının da bir göstergesi olarak değerlendirilebilir. Ağaç türlerinden 35’i bir bitkiadı (fitonim) ile kayıtlıdır. Özellikle çok eski dönemlerden bu yana meyvelerinin kullanıldığı bilinen; ceviz, ayva, kestane, iğde, zeytin ve şeftali buna örnek verilebilir. Bölgenin bazı yörelerinde aynı türe farklı adlar verildiği gibi farklı türlerin de aynı yöresel ad ile anıldığı belirlenmiştir. Bu ortak adlardan “Çitlenbik” adı Celtis australis L. ve Pistacia terebinthus L. türleri için, “Kızılcık” adı Cornus mas L., Crataegus monogyna Jacq., Juniperus oxycedrus L. türleri için kullanıldığı tespit edilmiştir. Ayrıca yaygın olarak kızılçam olarak bilinen Pinus brutia Ten. ve karaçam adı ile tanınan Pinus nigra J. F. Arnold. subsp. pallasiana (Lamb.) Holmboe türleri de akçam olarak ortak ad ile de adlandırılmaktadır. Sonuç olarak, geleneksel kullanım açısından önem taşıyan çok sayıda ağaç türünün bölgede bulunduğu ve bitkiadları açısından da önemli bir birikimin olduğu görülmektedir

A 76-year-old man developed a rectovesical fistula after rectal resection for adenocarcinoma complicated by peritonitis with the necessity of the creation of a colostomy. The patient was undergone a rectosigmoidoscopy with the placement of clip-type Ovesco to close the fistula, but this technique resulted ineffective. A robot- assisted closure of the rectovesical fistula was performed using Xi Da Vinci System. The surgical procedure will be divided into 3 parts: longitudinal median cystotomy, excision of the fistula tract, and the closure of the anterior rectal wall and bladder with interposition of omentum, between the suture lines of the rectum and bladder, to prevent fistula recurrence. The patient removed the catheter after 4 weeks of surgery and the patient remained free of urinary leakage from the anus. In February 2021, the surgery for intestinal re-anastomosis was performed. Robotic surgery is a good approach for the treatment of rectovesical fistula when the endoscopic treatment was unresolving
The Effect of A ‘Covid Tent’ On Emergency Department Efficiency and Patient Satisfaction: A Single Site Retrospective Study
Authors: E. Rappaport Douglas
Published: December 2022

Background:Overcrowding in Emergency Departments is associated with poor patient outcomes and low patient satisfaction; overcrowding has been exacerbated by the ongoing Covid-19 pandemic. One intervention used in both the H1N1 pandemic and the current Covid-19 pandemic is the deployment of temporary structures such as surge tents. Data on the effectiveness of such interventions is currently lacking. Methods:In this retrospective study, we assess ED length of stay (LOS), percent of patients leaving without being seen, and 72-hour return rate in the time period during tent operation with equivalent time periods before and after tent use. Differences in outcomes were modeled and tested using Generalized Estimating Equations (GEEs) methodology and controlled for emergency severity index (ESI). Results:Deployment of a Covid tent was associated with reduced LOS (227.5 vs. 214.5 min, ESI-adjusted p = 0.02). Additionally, we observed a significantly reduced rate of patients leaving without being seen (0.8% vs. 0.2%, ESI-adjusted p < 0.001) without any increase in the 72-hour return rate (4.2% vs 4.2%, ESI-adjusted p = 0.98) during the period of Covid tent operations. Conclusion:This data suggests that the deployment of temporary structures such as tents is an effective means of decompressing EDs in the setting of the Covid-19 pandemic.
Kryteria spełnienia w ojcostwie. Interpretacja i pytanie o aktualność wzorca spolegliwego opiekuna na przykładzie Józefa z Nazaretu
Authors: Zientkowski Przemysław
Published: December 2022

Artykuł jest próbą pedagogicznego ujęcia odpowiedzi na pytanie: jakie kryteria spełnienia w ojcostwie można przyjąć stawiając za wzór współczesnemu mężczyźnie Józefa z Nazaretu? W opracowaniu, poprzez bazowanie tylko na biblijnym opisie starano się zmniejszyć dystans, jaki pomiędzy opiekunem Jezusa a współczesnymi ojcami wytworzyła tradycja i pobożność ludowa. Tak przedstawiona postać św. Józefa wydaje się bliższa współczesnym mężczyznom i łatwiejsza do uznania za wzór.

W badaniach przyjęto perspektywę pedagogiczną. Najpierw naszkicowano pedagogiczne tło analiz, uzasadniając wartość pedagogicznych inspiracji biblijną figurą św. Józefa. Następnie nakreślono chrześcijańską wizję ojcostwa, aby skorelować perspektywę pedagogiczną z biblijnym kontekstem badań. Główną część artykułu obejmuje interpretacja fragmentów Ewangelii, w których są opisane sceny z życia Józefa. Interpretacja jest ukierunkowana na wskazanie cech tego przykładowego ojcostwa i odniesienie ich do kontekstu doświadczenia ojcostwa współczesnego pokolenia mężczyzn. Ojcostwo św. Józefa cechuje: odwaga, praca, poświęcenie, odpowiedzialność. Wnioskiem mającym wartość pedagogiczną, do którego doprowadziły analizy źródeł, jest wskazanie, że ojcostwo św. Józefa nie jest przykładem „jak poczuć się spełnionym” w ojcostwie, ale jak „spełniać się” w nim.
Management of the quality characteristics of the working surfaces of complex profile products during mechanical processing

Published: December 2022

The paper considers the temperature field model, which is formed in the surface layer of complex profile products during their processing in finishing operations. These operations are associated with defects in the surface layer of products, such as burns, cracks, and tensile stresses. Which significantly affects the reliability and durability of these parts during their operation. These defects, being local stress concentrators in operational conditions, lead to premature failure of products, even though the load on them forms stresses, the value of which does not exceed the limit values. The model is built based on the solution of the product's initial boundary value problem of thermal conductivity. Functional relationships of technological parameters with the grinding temperature obtained based on the model reflect the state of the treated surfaces for products with complex profiles and allow using appropriate techniques to eliminate burns on the treated surfaces. The study of the conditions for improving the quality of the treated surfaces by eliminating defects such as cracks and burns was carried out mainly at the level of identifying the connections of the temperature fields that are formed with technological parameters, physical and mechanical properties of the polished materials and the geometry of the products. It was established that when grinding complex profile products from a larger radius in the direction to a smaller one, the temperature increased in proportion to the angle of inclination of the treated surface. The adequacy of the built model was checked on the example of grinding conical products made of steel with known physical and mechanical characteristics, the choice of tool, and the designation of processing modes. Analysis of the simulation results shows that the temperature of the machined surface increases as the machining tool approaches a smaller diameter along the conical surface. This area of conical products' machined surface is most prone to defect formation during finishing operations. Therefore, when assigning treatment modes for such surfaces, they should be assigned with the condition that when the processing tool approaches the part of the conical surface with a smaller diameter, the temperature formed on it should not exceed the permissible values that ensure the required quality. Analysis of the results of numerical calculations of temperature fields showed sufficient accuracy according to the boundary conditions of the simulation.

With the expansion and development of Sri Lanka's economic practices and the modernization, client expectations for commercial building facilities have tremendously enhanced. Therefore, commercial building management has more focused on providing more effective and efficient buildings facilities to satisfy varied client requirements. Hence, commercial buildings need to consume a huge amount of energy to provide these facilities. However high energy consumption has caused to increase the energy cost, which takes a large proportion of the operation cost of commercial buildings. Ultimately all these causes adversely impact on the profit and the overall financial performance of the commercial buildings. Therefore, identification of main affecting ices which utilize energy mostly and factors effecting for the energy consumption by different building services is highly required for commercial buildings to gain economic advantage and to be sustainable firms. Through conducting a comprehensive literature review, the energy consumption of commercial buildings, energy management, including benefits of using energy management have been reviewed. Subsequently, a qualitative research choice was used to achieve the research aim. Semi-structured interviews were accompanied with 20 participants who are working in commercial buildings who are working in building management department and financial department respondents. Collected data were analyzed using manual content analysis technique. The empirical findings revealed the challenges of high energy consumption and reasons for growing energy consumption in commercial buildings. Further, widely used energy sources in commercial buildings were and finally, factors effecting on the energy consumption of commercial buildings in Sri Lanka were identified

Majority of the school-aged children with Autistic Spectrum Disorder (ASD) are excluded from education, globally. And those who are engaged in education, are being educated separately confronting social segregation. Education is a fundamental human right that highlights the importance of promoting inclusive schools, enabling education for differently abled children in typical schools. This study investigates the appropriateness of the built environment and available facilities of existing local schools imposed on students with ASD. Thus, four schools were evaluated; two with autistic students and two without them. A photographic survey was conducted as the methodology to evaluate the presence of the relevant spaces and their qualities. Five types of spaces were identified of which 12 spatial qualities were examined in each school. The results of the study demonstrate that the built environment of both existing special and mainstream schools consist a significant level of required spatial availability in three of the identified spatial categories while the availability of relaxing and treatment spaces to facilitate students with ASD are considerably low. Thus, the findings insist on the necessity of improvements in local school environments focusing on crucial space categories to educate students with ASD by making the schools inclusive.

Rivers have a significant role in the coastal sediment budget as the primary sources of natural sediment. Further, it is essential to comprehend the minimum grain size threshold, also known as the littoral cutoff diameter (LCD), in order to determine the actual contribution of river sediment load to the littoral beach. This study aims to present the LCD as a crucial variable worth taking into account at the regional level when budgeting for littoral sediments. Maha Oya River located on a severely eroding coastline between Negombo and Chilaw on the western coast of Sri Lanka was focus in this study. Here, we collected forty-four beach samples from the swash zone and berm crest during two sediment sampling surveys in March and October 2022. Concurrently, a streamer-type sediment trap was placed at 2 km upper streams of Maha Oya River to capture the bottom to 1.5 meters river sediment load. Sediment samples were sieved by mechanical sieving method in the classic Wentworth grain size scale (63-2000 μm). Additionally, the statistical properties of a grain size distribution, including LCD, skewness, kurtosis, and median grain size (D50), were investigated for sediment samples. Average D50 value on the beach was found to be 394 μm of medium sand that was moderately sorted, symmetrical, and mesokurtic, compared to 655 μm of coarse sand that was poorly sorted, fine skewed, and mesokurtic in river sediment. The LCD values was 141 μm on the beach studied herein, that indicated 10% of the river sediment in the lowest 1.5 m layer may not have remained on the beach in any significant quantity. Therefore, by using the concept of LCD, it is possible to quantify the potential overestimation of river sediment loads to the coastal sediment budget.
