Published: September 2021

Background

Ulcerative colitis (UC) is a chronic inflammatory disease with an increasing incidence in the world. Qingre-Chushi therapies (QC) can alleviate clinical symptoms. Therefore, a network meta-analysis was conducted to systematically evaluate the efficacy and safety of QC in the treatment of active UC patients.

Methods

7 databases were screened and relevant randomized controlled trials were selected. The tools of Cochrane Handbook and the GRADE system were conducted to assess the quality of outcomes. Pooled risk ratio or standard mean difference was calculated with 95% credible interval for outcomes measurement using the random-effects model. The surface under the cumulative ranking curve (SUCRA) was performed to rank the treatments. The larger SUCRA scores, the more effective interventions.

Results

A total of 3560 articles were identified and 21 studies including 1829 participants were included for further analysis. Totally, 9 therapies regimens were compared: oral mesalazine, mesalazine enema, mesalazine suppository, oral mesalazine + mesalazine enema, oral QC, oral QC + oral mesalazine, QC enema, oral QC + QC enema, and oral mesalazine + QC enema. Based on the SUCRA plot, oral QC + oral mesalazine was the best treatment in inducing clinical response; oral QC + QC enema had the best efficacy in the improvement of Mayo scores and alleviating abdominal pain; oral mesalazine + mesalazine enema was the optimal therapy in the endoscopic improvement and reducing diarrhea; QC enema + oral mesalazine was the best option in preventing bloody stool.

Conclusion

This study confirmed the efficacy and safety of QC in treating active UC and suggested that the combination of oral medications with topical can achieve more benefits.

Authors: Roy Nitai , Amin Md. Bony , Maliha Maskura Jahan , Sarker Bibhuti , Aktarujjaman Md , Hossain Ekhtear , Talukdar Gourango
Published: September 2021

Background and objectives

The COVID-19 pandemic has negatively impacted health systems worldwide, including in Bangladesh, limiting access to family planning information (FP) and services. Unfortunately, the evidence on the factors linked to such disruption is limited, and no study has addressed the link among Bangladeshis. This study aimed to examine the socioeconomic, demographic, and other critical factors linked to the use of FP in the studied areas during the COVID-19 pandemic.

Methods

The characteristics of the respondents were assessed using a cross-sectional questionnaire survey and descriptive statistics. The variables that were substantially linked with FP usage were identified using a Chi-square test. In addition, a multivariate logistic regression model was used to identify the parameters linked to FP in the study areas during the COVID-19 pandemic.

Results

The prevalence of FP use among currently married 15–49 years aged women was 36.03% suggesting a 23% (approximately) decrease compared to before pandemic data. Results also showed that 24.42% of the respondents were using oral contraceptive pills (OCP) which is lower than before pandemic data (61.7%). Multivariate regression analysis provided broader insight into the factors affecting FP use. Results showed that woman’s age, education level of the respondents, working status of the household head, locality, reading a newspaper, FP workers’ advice, currently using OCP, ever used OCP, husbands’ supportive attitude towards OCP use, duration of the marriage, ever pregnant, the number of children and dead child were significantly associated with FP use in the study areas during COVID-19 pandemic.

Conclusions

This study discusses unobserved factors that contributed to a reduction in FP use and identifies impediments to FP use in Bangladesh during the COVID-19 epidemic. This research further adds to our understanding of FP usage by revealing the scope of the COVID-19 pandemic’s impact on FP use in Bangladesh’s rural and urban areas.

Published: September 2021

Knowledge of the ecology of the fish fauna associated with kelp (primarily Macrocystis pyrifera) forests in Southern Patagonia is scarce, especially in how abiotic and biotic variables influence their structure, diversity, and distribution. This information is important for the management and conservation of this unique ecosystem, which has minimal anthropogenic impacts at present. We analyzed data from 122 quantitative underwater transects conducted within kelp forests at 61 stations from Chile’s southern Patagonian fjords to the Cape Horn and Diego Ramirez archipelagos and the southern tip of Argentina, including the Mitre Peninsula and Isla de los Estados. In total, 25 fish species belonging to 13 families were observed. Multivariate analysis indicated that there are significant differences in fish assemblage structure among locations and wave exposures, which was driven primarily by Patagonotothen sima and Paranotothenia magellanica, which occurred on exposed and semi-exposed stations. P. cornucola was mainly distributed across sheltered stations of the Kawésqar National Park. Temperature, salinity, depth, and kelp density influenced fish assemblage structure, with the highest diversity in areas with the lowest temperature and greater depth at Isla de los Estados. In contrast, species richness, diversity, abundance, and biomass were all lower in areas with high density of the understory kelp Lessonia spp., which might be driven by the absence of P. tessellata, P. squamiceps and P. cornucola, the most important species in terms of occurrence, abundance, and biomass. Our study provides the first broad-scale description of the fish assemblages associated with kelp forests along the southern cone of South America based on non-invasive visual transects, improving our knowledge of the distribution of fish assemblages across several environmental conditions in this vast and little-studied area.
Evaluation of thrombophilia testing in the inpatient setting: A single institution retrospective review
Authors: Siu Chun Ting , Wolfe Zachary , DelaTorre Martin , Rehim Erafat , Decker Robert , Zaffiri Kathryn , Lash Bradley
Published: September 2021

Background

Thrombophilia workup is typically inappropriate in the inpatient setting as testing may be skewed by anticoagulation, acute thrombosis, or acute illness.

Objective

To determine adherence of inpatient thrombophilia testing with institutional guidelines.

Patients and methods

A retrospective study to evaluate thrombophilia testing practices of adult patients who were admitted to Lehigh Valley Hospital at Cedar Crest with either venous thromboembolism or ischemic stroke in 2019. Testing included inherited and acquired thrombophilia. Patient charts were individually reviewed for three measured outcomes: 1) the number of appropriate thrombophilia testing in the inpatient setting; 2) the indications used for thrombophilia testing; 3) the proportion of positive thrombophilia tests with change in clinical management.

Results

201 patients were included in our study. 26 patients (13%) were tested appropriately in accordance with institution guidelines and 175 (87%) patients were tested inappropriately. The most common reason for the inappropriate testing was testing during acute thrombosis. 28 of the 201 patients had positive thrombophilia tests, but the reviewers only noted 7 patients with change in clinical management—involving anticoagulation change.

Conclusion

Our study revealed that a majority of inpatient thrombophilia testing did not follow institutional guidelines for appropriate testing and did not change patient management. These thrombophilia tests are often overutilized and have minimal clinical utility in the inpatient setting.
Comparative assessment of the relationship between coliform bacteria and water geochemistry in surface and ground water systems
Authors: Aram Simon Appah , Saalidong Benjamin M. , Osei Lartey Patrick
Published: September 2021

The occurrence of pollution indicator bacteria (total and faecal coliform) has been used as a sanitary parameter for evaluating the quality of drinking water. It is known that these indicators are associated with disease causing organisms which are of great concern to public health. This study assessed the relationship between coliform bacteria and water geochemistry in surface and ground water systems in the Tarkwa mining area using logistic regression models. In surface water sources, higher values of chloride (OR = 0.891, p<005), phosphates (OR = 0.452, p<0.05), pH (OR = 0.174, p<0.05) and zinc (OR = 0.001, p<0.05) were associated with lower odds of faecal coliform contamination. In groundwater sources, higher values of phosphates (OR = 0.043, p<0.001), total dissolved solids (OR = 0.858, p<0.05), turbidity (OR = 0.996, p<0.05) and nickel (OR = 6.09E-07, p<0.05) implied non-contamination by faecal coliform. However, higher values of electrical conductivity (OR = 1.097, p<0.05), nitrates (OR = 1.191, p<0.05) and total suspended solids (OR = 1.023, p<0.05) were associated with higher odds of faecal coliform contamination of groundwater sources. Nitrates and total suspended solids, in this case, were completely mediated by the heavy metals. For total coliform in surface water systems, higher values of magnesium (OR = 1.070, p<0.05) was associated with higher odds of total coliform contamination while higher values of phosphates (OR = 0.968, p<0.05) was associated with lower odds of total coliform contamination although the presence of heavy metals completely mediated these relationships. For ground water systems, higher values of pH (OR = 0.083, p<0.05), phosphates (OR = 0.092, p<0.05), turbidity (OR = 0.950, p<0.05) and chloride (OR = 0.860, p<0.05) were associated with lower odds of total coliform contamination. However, higher values of total suspended solids (OR = 1.054, p<0.05) and nitrates (OR = 1.069, p<0.05) implied contamination of total coliform in ground water sources. The relationship between nitrates and total coliform were mediated by the heavy metals. This study establishes the need to monitor, manage and remediate surface and ground water sources for potential disease causing microbes in ways that takes into consideration the factors that create different conditions in the two water systems. This study validates the usefulness of statistical models as tools for preventing surface and ground water contamination.
Dispatches from the age of fire
Authors: Macarow Keely
Published: September 2021

In 2019–2020, fires ravaged large areas of Australia devastating land, infrastructure and human and non-human lives. While Australia has a history of fires and fire management, large regions of the eastern states were devastated by super fires fueled by their own weather, and changes to the climate. However, Australian governments, political and business leaders continue to invest in fossil fuels and disregard the impact of the climate crisis. Meanwhile, the nation is at a tipping point due to the effects of global heating, extreme weather events, natural disasters and biodiversity loss. This article explores the climate crisis through a discussion of first-hand accounts of people directly affected by the 2019–2020 bushfires in Australia. These harrowing and philosophical accounts of the fires were gleaned from poetry, videos, websites and non-fiction sources and demonstrate the human lived experiences of the climate crisis and how we can move forward for climate justice.

Ghosts, murder and mutation: The portrayal of pandemics in children’s and YA fiction
Authors: Webb Jean
Published: September 2021

The coronavirus pandemic has stimulated a number of texts, which are aimed at helping children to cope with situations alien to them. For example, the picture book Staying Home by Sally Nichols and Vivienne Schwarz (2020) deals with the conditions of lockdown and family isolation, whilst Piperpotamus by Annis Watts endeavours to explain COVID-19. This pandemic is not the only such event in history. The Black Death swept across Europe (1347–51) followed by the Spanish flu pandemic (1918–20). Both of these have stimulated historical fiction for older children and Young Adults and have done so by employing differing literary approaches. For instance, Cat Winters’ In the Shadow of Blackbirds (2013) incorporates a ghost story set against the contexts of séances and spirit photographers as the bereaved hope to gain comfort, whilst Charles Todd’s An Unmarked Grave (2012) is a murder mystery. Dystopian science fiction has also been employed to examine the equivalent circumstances of such pandemics. The plague in Gone (2008–14) by Michael Grant follows a nuclear disaster, which has produced a world where only those under fifteen have survived beneath a dome created by a young autistic child at the point of the explosion. Unforeseen forces have erupted resulting in mutation where individuals have supernatural powers taking them into a posthuman state. Their world is later blighted by plague and the children have to deal with remaking their lives and their society without the help of adults. This article will consider the various ways that such texts have approached these world-changing disasters and the common themes, which emerge to give our current generation of children ways of thinking about their present and their future.

Published: September 2021

El presente artículo tiene como objetivo demostrar los impactos y riesgos en la violencia de género contra las mujeres en el confinamiento por el coronavirus y las políticas públicas adoptadas por los gobiernos, especialmente el del Ecuador. Es un estudio descriptivo que se sustenta en los informes de las organizaciones internacionales de protección a las mujeres y de los diferentes medios de radiodifusión digital. Como resultado se identificó, que en las primeras semanas del confinamiento las mujeres no pudieron acudir a denunciar debido al confinamiento y la restricción de movilización, a diferencia que actualmente se conoce que existe un número incalculable de mujeres víctimas de violencia ejercida por la pareja durante el confinamiento, y que las políticas adoptadas no han disminuido este tipo de violencia; al contrario, se va incrementando.
MAINSTREAMING HUMAN RIGHTS THROUGH THE ENLARGEMENT POLICY: THE CASE OF THE WESTERN BALKAN COUNTRIES
Authors: Skara Gentjan
Published: September 2021

The EU enlargement has been considered as the EU’s most efficient foreign policy instrument in terms of its ability to transform communist countries into functional democracies and open market countries. Since the beginning of 1990s, the promotion of human rights has become prominent topic either for the consolidation of human rights within the EU or outside. The argument of this paper is that the EU enlargement policy has influenced Western Balkan countries to improve their domestic legislation in the area of human rights. The paper demonstrates, firstly, how has evolved the EU human rights actorness from the establishment of the EE Community and secondly, discuss strategies and instruments used by the EU to export its norms and values in the Western Balkan countries. The paper addresses the following research question: how, whether and to what extent, the EU has promoted human rights in the Western Balkan countries. Throughout this paper, a doctrinal legal research has been used to analyze EU primary and secondary sources. The value of this paper lies in its comprehensiveness in drawing a complete picture of EU role in promoting human rights in Western Balkan countries through enlargement policy and to discuss the impact of the EU Charter of Fundamental Rights in the candidate countries.

Published: September 2021

A 21. század kihívásai sokrétű feladatot rónak az oktatásra és a pedagógusokra, melyek érintik a testnevelés tanítását is. Az iskola mint oktatási-nevelési színtér nem tekinthető állandónak, folyamatosan változik a társadalmi, környezeti, valamint az oktatást érintő változásokkal együtt. Az infrastrukturális és tárgyi feltételek szorosan kapcsolódnak a testnevelés tanításához, befolyásolják annak színvonalát is. A létesítményhelyzettel kapcsolatos felmérések száma korlátozott, az átfogó, több szempontú adatgyűjtés, valamint a széles körű elemzések száma alacsonynak mondható. A téma ugyanakkor fontos, hiszen a testnevelés-tanítás gyakorlatában és a „közvélekedésben” is úgy van jelen a kérdés, hogy alapvető fontosságú az infrastruktúra a testnevelés tanításához. Ez esetenként mintegy feltételként vagy korlátozó tényezőként is megjelenik a tantárgy tanításával kapcsolatban. A tanulmány emiatt helyzetfeltáró jelleggel készült, elemzi az iskolák teremellátottságának kérdését, célja bemutatni, hogy milyen infrastrukturális helyzet jellemzi az iskolákat, valamint létesítményhiány esetében milyen helyszíneken valósul meg a testnevelés óra. Az eredmények alapján elmondható, hogy az iskolák harmadában nem jelentett gondot a mindennapos testnevelés bevezetése, valamint a sportcélú létesítményeken kívül számos egyéb helyszínnel pótolják az esetlegesen felmerül létesítményhiányt.

Preconcentration of Pesticides from Environmental Samples
Authors: Joarder Rajib
Published: September 2021

A simple, sensitive, quick, easy and efficient (SSQuEE) analytical technique based on cloud point
extraction (CPE) has been developed for the determination of different pesticides present in soil and
water with high performance liquid chromatography separation and ultraviolet detection. The
environmentally friendliness surfactant like Triton X -100, compared to Tween series of non-ionic
surfactant can effectively extract imidacloprid (insecticide), flusilazole (fungicide) and atrazine (herbicide)
at cloud point temperature at 67 ºC, 82 ºC and 62 ºC, respectively. To reach the optimum extraction
efficiency, different experimental parameters like surfactant concentration, salt type and its
concentration, equilibrium time and temperature, pH were observed. At the optimum conditions, linear
regression coefficient of the standard curves was greater than 0.9924. The limit of detection of imidacloprid,
flusilazole and atrazine were 0.10 μg L-1, 0.24 μg L-1, 0.15 μg L-1 and recovery percent are 99.71 %,
88.1% and 89.74%, respectively.

Published: September 2021

The removal of tartrazine dye from aqueous solution using g-C3N4/Fe3O4 nanocomposites was studied.
The g-C3N4/Fe3O4 nanocomposites were synthesized using simple co-precipitation method. The
synthesized nanocomposites were characterized by spectral (UV-Vis DRS, FT-IR) and analytical
(PXRD, SEM, EDAX, HRTEM) techniques. Photodegradation of tartrazine dye using the synthesized
catalyst was studied. The g-C3N4/Fe3O4 nanocomposites exhibited excellent photocatalytic performance
by degrading tartrazine (90%) at 0.1 g/L of catalyst and 20 μM initial dye concentration at pH 3. The
excellent performance by the catalyst was attributed to the highest electron hole pair generation. The
kinetic study revealed that the photodegradation of tartrazine obeyed pseudo first-order kinetics.

Synthesis and Characterization of Architecturally Modified
Mesoporous-Microporous MFI (Mobil Five) Zeolite with Enhanced Catalytic Activity
Authors: Pathak Dhanju Mani , Ghosh Pankaj Kumar , Shah Kishor Kr , Talukdar Anup Kumar
Published: September 2021

Four samples of MFI zeolites with silica to alumina ratio of 100 and using different silica to carbon
mass ratios (1:1, 1:4, 1:8 and 1:12) were synthesized by using carbon black particles. Silica-alumina
molar ratio imposes the framework structure to the synthesized zeolites. In general with an increase in
the silica-alumina molar gel ratio, the thermal stability, acid resistance and hydrophobicity of the
product increases and ion-exchange capacity decreases. A higher molar ratio (as high as 100) of silica to
alumina is considered. ZSM-5 zeolites being mainly microporous, their use as catalyst is restricted
only to small molecules. So, by introducing mesopores in zeolite framework, we basically tried to
overcome the limited use of ZSM-5 in reactions involving large molecules. Pore structure of ZSM-5
can be modified by using carbon black particles during synthesis. Such type of synthesis can be used
to introduce the mesopore and to decrease the crystal size of ZSM-5 zeolite. Different silica to carbon
mass ratio is used to study the pore structure and crystal size of ZSM-5 zeolites under autogeneous
pressure without adding any promoter or organic solvent. The synthesized samples were characterized
by different techniques such as X-ray diffraction, FTIR spectroscopy, scanning electron microscopy,
TGA and N2 adsorption-desorption isotherm. The samples exhibit high crystallinity (84-91%). The
particle size ranged from 2.8 to 7.3 μm. Mesopore to micropore ratios was found to increase with
increasing silicon to carbon mass ratio. These structurally modified meso-micro zeolite showed
enhanced activity in the benzyl alcohol esterification reaction using acetic acid. The selectivity towards
benzyl acetate in all the cases was found to be 100%.

A heterocyclic ligand, 5-(2-(4-chlorophenyl)-1H-benzo[d]imidazol-1-yl)quinolin-8-ol and its Co(II),
Ni(II), Cu(II) and Zn(II) complexes were synthesized and characterized by elemental analysis and
spectroscopic techniques. According to the spectral analysis, the ligand acts as a bidentate ligand and
coordinating through the nitrogen and deprotonated oxygen atoms. For Cu(II) and Ni(II) complexes,
spectral analysis reveals square planer geometry, whereas Co(II) and Zn(II) complexes have tetrahedral
geometry. The antibacterial results show that Zn(II) complex is more effective than the other metal(II)
complexes examined. The ligand and its metal complexes were tested for anticancer activity using the
MTT assay with cisplatin as the reference drug against A549, MCF7, and HCT116 cancer cell lines.
Results showed that the metal(II) complexes were shown to be more active than the ligand, especially
Zn(II) complex being the most potent among this series.

Published: September 2021

BACKGROUND Telemedicine involving teleconsultation has been a boon to people during this pandemic situation. Safeguarding one against the infection should not put people who are in dire need of medical help feel helpless and desperate. Teleconsultation, which was previously used for people who did not have access to medical help due to geographical isolation, has come to the rescue of people during this pandemic, and sometimes it is the only timely help that is available to people in need. We wanted to measure the patient satisfaction level regarding the use of telemedicine for psychiatric and psychological consultations during the Covid-19 pandemic. METHODS The level of patient satisfaction was measured using the patient experience and satisfaction survey’ proposed (The Research and Development Survey-RANDS) (measuring patient experience and satisfaction to telemedicine, 2020) to measure the level of satisfaction to telemedicine during this pandemic situation, regarding the use of telemedicine for patients who consulted doctors and psychologists in a psychiatric hospital in South India. People who participated filled the questionnaire through google form links sent to them. RESULTS The results indicate that 28 % of people who consulted psychiatrists, recorded scores indicating that they were satisfied with the teleconsultation service, while 71 % of people who consulted psychologists reported being highly satisfied with the consultation. This study indicated that some still preferred direct interaction with psychiatrists as evidenced by 72 % of people feeling dissatisfied with teleconsultation. CONCLUSIONS This study shows that with people struggling with mental illness direct interaction is crucial in the treatment process, however, teleconsultation could be used for emergencies to ensure compliance with medication and for monitoring symptoms in patients.

Visual Morbidity in Diabetic Retinopathy Associated with Diabetic Nephropathy - Our Experience in a Multispecialty Tertiary Hospital in Chennai, India
Authors: Venkatakrishnan Praveena , Annamalai Radha , Muthukumar Muthayya
Published: September 2021

BACKGROUND The increased prevalence of diabetes mellitus (DM) worldwide has resulted in worsening diabetic retinopathy (DR) and nephropathy. The pathophysiological changes that occur at a cellular and anatomical level are similar in DR and DN. The risk factors for DR and DN are common hence investigating both is paramount to reduce morbidity. We wanted to study the association of diabetic retinopathy and diabetic nephropathy, their ophthalmic features, patterns of vision loss and extent of ocular morbidity. METHODS This is a retrospective observational study performed on 100 diabetic patients over 2 years. Patients with a confirmed diagnosis of DN based on clinical evaluation and laboratory tests were included. Ophthalmic evaluation and investigations were done and DR was classified based on early treatment diabetic retinopathy study (ETDRS). RESULTS Mild non-proliferative diabetic retinopathy (NPDR) occurred in 60 %, moderate to severe NPDR in 9 %, proliferative diabetic retinopathy (PDR) in 4 % and no diabetic retinopathy in 27 %. Macula was involved in 48 % with clinically significant macular edema (CSME) in 33 % and ischemic maculopathy in 5 %. Retinopathy occurred in 3 % after 5 years and in 40 % after 20 years of DM. The incidence of DN +DR was 65 % and statistical significance was noted with longer duration of diabetes, higher serum creatinine, proteinuria, lower haemoglobin, decreased GFR, higher age and higher lipid levels (P = 0.04). Improvement in vision was seen in 63 % after blood sugar control with laser photocoagulation, 27 % with laser alone and 7 % of patients with intravitreal anti-VEGF CONCLUSIONS DR and DN have an overlapping significant association and all patients have to be screened for both to prevent ocular morbidity.

Determining success factors for project with supervised machine learning
Authors: Saxena Grant
Published: September 2021

Every year, enormous project failure rates plague business companies across the globe, costing millions of dollars for each failed project. It is critical to understand the factors that influence project success. The goal of this study is to empirically discover the factors that lead to a successful project. This study used data from 469 projects to use three distinct supervised machine learning methods for classification: a) The Support Vector Machine (SVM), 2) The Probit regression, and 3) the Logistic regression. Five factors have been chosen.: Support from the top management, Technical skills, Client’s acceptance, Communication, and Monitoring. The findings of the SVM study revealed that SVM could accurately predict successful and unsuccessful projects. The findings of Logistic and Probit regression revealed that project success is more likely if project managers get appropriate top-level support and if the project team has sufficient technical capabilities. This study also discovered that good communication and control improve the odds of a project's success. However, according to the results of this research, client acceptability is a minor success factor for a project.

One of the tasks of the modern educational process is to support students’ selfdetermination in personal, social and professional spheres. The successful implementation of this task depends on the professional skills of teachers and ensures the formation of students' worldview, a strategy for their development and self-realization in accordance with social, moral and ethical norms. However, in practice, the readiness of teachers to complete this task is not sufficient for its successful implementation. This article is an attempt to systematize the historical background for the development of training teachers to support students’ self-determination, to identify the teachers’ functions to support students’ self-determination, to determine the readiness of teachers to support students’ self-determination. The methods of comparative analysis and synthesis of scientific knowledge were used. The results of this study can be used to plan activities to estimate the teachers’ readiness for students’ self-determination support, for programs of additional education and teachers’ advanced training.

The purpose of this article is to develop a forecasting technology that makes it possible to predict the learning outcomes of civil engineers’ students studying “Chemistry” during the first weeks of study. The method of cluster analysis of k-means was chosen as a diagnostic tool. The participants were the students of 19 academic groups of full-time bachelor's degree program. For the experiment, the results of current control group (with an accuracy of 0.5 points) were collected from 298 first-year students that were asked to predict (on a 100-point scale) their score for the course being studied. The developed technology allows predicting learning grades with satisfactory accuracy equal to 86.24%. Eight hypotheses were tested; the results can be divided into three clusters of students: those who received a positive score; those who achieved a satisfactory result; students who are required to pass the exam to obtain a “satisfactory” grade. The study contributes to the development of computer pedagogy. It can be useful for teachers (for recommending to visit consultations to students who cannot achieve good results on their own, for a more efficient distribution of exam session’s time). The results can be useful for students (as a motivation to put more efforts into studying some disciplines), and for tutors and deputy deans for academic affairs (to search for “problem” students and decrease possible academic failures early).
Engineering the “Islamic personality”: Muslim Brotherhood education between theory and practice
Authors: Elsässer Sebastian
Published: September 2021

The Muslim Brotherhood’s ideological belief in Islam as a comprehensive system (šumūlīya) implies ambitious ideas about forming and re-forming the minds, spirits and bodies of Muslim individuals through educational activities within the organisational framework of the Brotherhood. Internal debates reveal that actual educational practice in the Muslim Brotherhood balances different priorities and goals and allows a range of different expressions of Muslim subjectivity. Tensions between different, sometimes contradictory goals are solved theoretically by the concept of balancing (tawāzun) and practically by a division of labour within the movement that only requires a small elite to reach the highest levels of an “Islamic personality” (šaḫṣīya islāmīya). This article traces debates in programmatic and educational writings, in memoirs and in weblogs and social media outlets in order to reach a critical assessment of Muslim Brotherhood education in the Arab world, primarily between the 1980s and the mid-2010s and focused on Egypt and the Arab East.
A contribution to the technology and sources of lead in Byzantium: lead isotope analysis of ten Byzantine seals
Authors: Karagiorgou Olga , Merkel Stephen , Wołoszyn Marcin
Published: September 2021

This article presents the results of lead isotope analysis of ten Byzantine seals from the sigillographic collection of Robert Feind (Cologne). The report is preceded by an overview of pre-existing studies on lead use in the Byzantine Empire and a presentation of the investigated seals datable to the Early Byzantine (4 specimens), Middle Byzantine (5 specimens) and Late Byzantine period (1 specimen). Three seals are of imperial issue. The results of the analysis of lead are compared against the results of isotope analysis of other silver and lead artefacts from Late Antiquity and the Late Byzantine period. The isotop analysis leads to the following conclusions: (a) Many of the seals have isotope ratios consistent with Aegean-Bulgaria-Western Turkey sources; (b) Reused lead was also employed in the manufacture of seals; (c) There appear to be significant chronological and regional differences in the lead used for casting blanks in the eastern Mediterranean. The number of lead seals subjected here to analysis is admittedly too small for the results to be fully representative; still, they provide a starting point for more similar studies which will preferably include excavation finds with known and secure provenance.
The last century of the Chora Monastery: a new look at the tomb monuments
Authors: Melvani Nicholas
Published: September 2021

The present article re-examines the tomb monuments in the parekklesion and the outer narthex of the main church of the Chora monastery, which are generally thought to date from the early Palaiologan period. Based on the analysis of the iconography and style of the frescoes adorning the tombs, it is suggested that some of the burials should be re-dated at least a few decades later. The frescoes in the lunette of the Tomb of Michael Tornikes (Tomb D) appear to have been executed shortly after 1350 and the decoration of Tombs C and E must date from around the same time. The portraits in Tombs F and G date from the 15th century. The epigraphic evidence and the images illustrate the continuing use of the Chora by its patrons, members of various branches of the Tornikes, Asanes, Raoul, and Dermokaites families, during the last century of the monastery.
Imprisoned martyrs on the move: reading holiness in Byzantine martyrdom accounts
Authors: Papavarnavas Christodoulos
Published: September 2021

This paper shows that the protagonists of Byzantine Passions are often depicted as attaining holiness while on the move: after their arrest by pagan soldiers, Christian martyrs are subjected to travels for legal reasons. Drawing on the anthropological concept of liminality (Arnold van Gennep, Victor Turner), I will suggest that such inflicted travels or transfers in Byzantine Passions serve as liminal phases between interrogation, torture, imprisonment, and execution, by which the protagonists ascend to the state of holiness. The paper, structured in three major sections, focuses on scenes of ‘imprisoned martyrs on the move’ as delineated in both pre-Metaphrastic and Metaphrastic martyrdom accounts (fourth-tenth centuries). After a concise introduction to the theoretical background and the text corpus of this study, the main sections explicate the motif of imposed movement in conjunction with the literary construction of holiness, the spiritual formation of the audience, and the structure of a martyrdom narrative.
Of the nomophylax: John Xiphilinos’ scholia on the Basilica
Authors: Penna Daphne
Published: September 2021

The aim of the present study is to focus exclusively on the Basilica scholia of John Xiphilinos: to collect and record a list of his scholia and to analyse and evaluate specific lengthy scholia of his in detail. Scholia attributed to Xiphilinos have the heading “of the nomophylax”. We also encounter scholia under the heading “of Ioannes”, and it remains doubtful whether they can also be attributed to Xiphilinos. Based on the evidence some of the scholia with the heading “of Ioannes” are certainly attributed to the antecessor Ioannes Kobidas. Xiphilinos takes into account older legal material including antecessorian writings (Stephanus, Cyril, Theophilus and kata podas translations), as well as works of Athanasius of Emesa and Theodorus of Hermoupolis. Xiphilinos’ references to the rheton raise the question whether he had actually consulted manuscripts of the Digest. Arguments are brought in favour of this hypothesis.
Robust Hybrid High-Order Method on Polytopal Meshes with Small Faces
Authors: Droniou Jérôme , Yemm Liam
Published: September 2021

We design a Hybrid High-Order (HHO) scheme for the Poisson problem that is fully robust on polytopal meshes in the presence of small edges/faces.
We state general assumptions on the stabilisation terms involved in the scheme, under which optimal error estimates (in discrete and continuous energy norms, as well as

L

L^{2}

-norm) are established with multiplicative constants that do not depend on the maximum number of faces in each element, or the relative size between an element and its faces.
We illustrate the error estimates through numerical simulations in 2D and 3D on meshes designed by agglomeration techniques (such meshes naturally have elements with a very large numbers of faces, and very small faces).
Modeling evaluation on solid-liquid mixing characteristics in a dislocated guide impeller stirred tank
Authors: Gu Deyin , Zhao Fenghui , Wang Xingmin , Liu Zuohua
Published: September 2021

The solid-liquid mixing characteristics in a stirred tank with pitched blade impellers, dislocated impellers, and dislocated guide impellers were investigated through using CFD simulation. The effects of impeller speed, impeller type, aperture ratio, aperture length, solid particle diameter and initial solid holdup on the homogeneity degree in the solid-liquid mixing process were investigated. As expected, the solid particle suspension quality was increased with an increase in impeller speed. The dislocated impeller could reduce the accumulation of solid particles and improve the cloud height compared with pitched blade impeller under the same power consumption. The dislocated guide impeller could enhance the solid particles suspension quality on the basis of dislocated impeller, and the optimum aperture ratio and aperture length of dislocated guide impeller were 12.25% and 7 mm, respectively, in the solid-liquid mixing process. Smaller solid particle diameter and lower initial solid holdup led to higher homogeneity degree of solid-liquid mixing system. The dislocated guide impeller could increase solid particle integrated velocity and enhance turbulent intensity of solid-liquid two-phase compared with pitched blade impeller and dislocated impeller under the same power consumption.
Congenital hyperinsulinism: recent updates on molecular mechanisms, diagnosis and management
Authors: Giri Dinesh , Hawton Katherine , Senniappan Senthil
Published: September 2021

Congenital hyperinsulinism (CHI) is a rare disease characterized by an unregulated insulin release, leading to hypoglycaemia. It is the most frequent cause of persistent and severe hypoglycaemia in the neonatal period and early childhood. Mutations in 16 different key genes (ABCC8, KCNJ11, GLUD1, GCK, HADH, SLC16A1, UCP2, HNF4A, HNF1A, HK1, KCNQ1, CACNA1D, FOXA2, EIF2S3, PGM1 and PMM2) that are involved in regulating the insulin secretion from pancreatic β-cells have been described to be responsible for the underlying molecular mechanisms of CHI. CHI can also be associated with specific syndromes and can be secondary to intrauterine growth restriction (IUGR), maternal diabetes, birth asphyxia, etc. It is important to diagnose and promptly initiate appropriate management as untreated hypoglycaemia can be associated with significant neurodisability. CHI can be histopathologically classified into diffuse, focal and atypical forms. Advances in molecular genetics, imaging techniques (18F-fluoro-l-dihydroxyphenylalanine positron emission tomography/computed tomography scanning), novel medical therapies and surgical advances (laparoscopic pancreatectomy) have changed the management and improved the outcome of patients with CHI. This review article provides an overview of the background, clinical presentation, diagnosis, molecular genetics and therapy for children with different forms of CHI.

Subjectively perceived change in consumption along the living standards in old ages
Authors: Hegedüs Réka , Rádóczy Klaudia
Published: September 2021

THE AIMS OF THE PAPER

The aim of our research is to provide a picture of the conditions for providing the income background necessary for old age, the spending habits of the 50 plus age group, and to illustrate how the old ages goup of our survey, the elderly age group we survey perceives changes in their spending in the last 10-year.

METHODOLOGY

We used a representative personal survey with 500 Hungarian people. This survey was made in February 2020 on a targeted sample of the Hungarian population aged 50-70. In the analysis method, we used cluster formation, because we tried to identify groups showing different consumption changes based on the consumption categories of the Hungarian Central Statistical Office.

MOST IMPORTANT RESULTS, NEW FINDINGS

The results show that the people who participated in the survey had little perception of a change in their spending compared to their life 10 years before. On the other hand, our retirement income in old age may lag far behind the income in active, working years, so we can assume that if the significant decline in income did not affect consumption patterns, old-age income may be supplemented by savings in old age.

EMPIRICAL IMPLICATIONS OF THE RESEARCH

The clusters that we made shows well that the spendings of the 50-plus age group are also significant for the economy as a whole. The types of their expenditures is diverse and there is a lot of items that they would not necessarily be able to afford from an average income funded by the pension scheme. The characteristics of the clusters also show that there is a positive relationship between financial awareness (planning spending, exploring sales) and age. In our oppinion this is the reason why financial awareness education, the communications about this is very important. The financial management of households can be incorporated into the education of children from an early age.
