Published: November 2021

The aim: To assess the outcome of allogeneic transplant regarding the overall Survival (OS) and main predictors can effect the survival of such patients.
Materials and methods: The records of seventy-nine Iraqi patients diagnosed with non-promyelocytic AML, who underwent allogeneic bone marrow transplantation outside of Iraq between 2012 and 2019, had been reviewed. The information had been collected from the data available in Bone Marrow Transplant Centre in Baghdad Medical City. Overall survival had been calculated by Kaplan-Meier Method. Patients included in the study are those who were diagnosed with acute myeloid leukemia according to French American British classes with the exclusion of acute promyelocytic leukemia (M3), who were allotransplanted for being diagnosed with high risk cytogenetic, refractory to chemotherapeutic regimen, relapsed after achieving complete remission, secondary to transformation from other myeloid malignancies or remaining with positive measurable residual disease after treatment.
Results: The overall survival for 1 year, 2 years and 3 years were 63.20%, 55.09% and 46.58% respectively. The pre-transplanted factors found, no significant difference in overall survival regarding age, gender, extra medullary involvement. The transplant related criteria like stem cell source, presence of infection and type of conditioning regimen and incidence of any post-transplant complications do not predict overall survival apart from chronic graft versus host disease. Chronic GVHD were found to be significantly affecting overall survival.
Conclusions: The most common cause of death was disease relapse. Iraqi AML patients who were treated with allogeneic bone marrow transplant had shown to have encouraging overall survival.

Authors: Abdul Amir Rafah Habib
Published: November 2021

The aim: This study evaluates the effect of adding silanized halloysite nanotubes to the polymethylmethacrylate (PMMA) resin on its hardness, impact strength, transverse strength.
Materials and methods: Three groups of acrylic resin were prepared, one group without HNTs, was used as a control group (A). The other two groups contained 0.3% (B), 0.6% wt of silanized halloysite nanotubes (C). For each one, hardness, impact strength and transverse strength were measured. One-way ANOVA and Tukey’s test were used for comparison.
Results: Regarding to the impact test, there was no significant difference between 0.3% concentration and the pure (control) group while 0.6% concentration had significant decrease compared to the pure group and so between the 0.3% group 0.6% group. For the hardness test, the 0.3% group had no significant difference with the pure group and a significant difference between group 0.6% group and the pure group while there was a no significant decrease between the 0.3% and 0.6% group with the higher hardness mean in the 0.3% compared to 0.6% group. For the transverse strength, both 0.3% wt concentration and 0.6% concentration showed significant difference compared to the pure group and also between each other with the lowest impact strength in 0.6% group followed by 0.3% group with the highest transverse strength in the pure group.
Conclusions: The silanation of halloysite nanotubes reduces the mechanical properties of the heat-cured acrylic denture base material. The more concentration of silanazed halloysite nanotubes is added, the more weakening occurs in the acrylic material relating to the hardness, transverse strength and impact strength.

Published: November 2021

The virus responsible for the COVID-19 pandemic is the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which belongs to the genus Betacoronavirus. This genus also includes the severe acute respiratory syndrome coronavirus (SARS-CoV) and the Middle East respiratory syndrome coronavirus (MERS-CoV). The common symptoms of COVID-19 infection are fever and respiratory symptoms, but it can also involve the gastrointestinal tract (GIT), resulting in manifestations such as diarrhea, nausea and/or vomiting and abdominal pain. The emergence of COVID-19 led to public health emphasis on droplet transmission and precautions of contact with respiratory secretions. However, mounting evidence demonstrates detection of SARS-CoV-2 RNA in stool samples of COVID-19 patients. It has also been demonstrated that the host receptor angiotensin-converting-enzyme-2 (ACE-2) is highly expressed not just in respiratory cells but also in gastrointestinal sites involving the glandular cells of gastric, duodenal, and rectal epithelium. This suggests that SARS-CoV-2 can infect the digestive system, serving as another route of transmission. This review aims to study the prevalence of some of the gastrointestinal manifestations following COVID-19 infection and findings of positive SARS-CoV-2 RNA in stool specimens while making parallels to the severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS) infection. We will also discuss the possible pathophysiology of COVID-19 related gastrointestinal involvement.
Mini-München findet Stadt
Authors: Lefevre Laura
Published: November 2021

Eins der vielen Ziele der Spielstadt Mini-München ist es, Kindern und Jugendlichen, die Prozesse einer Stadt zugänglich machen. Alle zwei Jahre werden in den ersten drei Wochen der Sommerferien in der Modell-Stadt Einrichtungen und Strukturen einer realen Stadt nachgebaut und für die Gestaltung durch Kinder und Jugendlichen geöffnet. Dieser Beitrag möchte einen Einblick in den pädagogischen Ansatz Mini-Münchens geben und anhand eines konkreten Beispiels aus der Spielstadt Denkanstöße zu der Frage liefern, welchen Blick eine kritische Stadtforschung auf das Phänomen Spielstadt werfen kann.
Die Analyse des Spielstadt-Projekts zeigt, dass Kinder in der Auseinandersetzung mit der Planung einer mini-städtischen Infrastruktur ethische Vorstellungen von sozialer Gerechtigkeit und Naturschutz reflektieren. In ihrer Aushandlung greifen sie auch auf gesellschaftliche Diskurse urbaner Ethiken zurück. Gleichzeitig fällt es ihnen schwer, diese Ideen im tatsächlichen städtischen Raum umzusetzen, da dieser ein Raum von generationaler Ordnung und Machthierarchien bleibt, dessen Aneignung oftmals der Zustimmung Erwachsener bedarf.
Die Stadt als „Werkzeug“ – ein neuer Ansatz für die Stadtforschung?
Authors: Krahmer Alexander
Published: November 2021

Das Buch bietet eine Einführung und eine theoretische Reflexion über die Stadt, die mit zwei grundsätzlichen Fragen beginnt: Was ist eine Stadt? Wie lässt sich das bisher über sie gesammelte Wissen sinnvoll unter einem Blickwinkel zusammenfassen? Der Autor sucht Antworten darauf im theoretischen und im praktischen Feld der Stadtforschung. Innovativ ist vor allem sein Versuch, diese Fragen anhand von Bedeutungfacetten des Begriffs „Stadt“ in verschiedenen Sprachen klären zu wollen. Das Buch bietet einen vielseitigen, aber selektiven Einblick in die heutige Forschung inklusive vieler bedenkenswerter, aber nicht immer überzeugender Ansätze.
Smarte Kindheiten

Published: November 2021

Mit der Smart-City-Vision wird die Hoffnung verbunden, drängende ökologische, ökonomische und soziale Krisen in Städten zu überwinden und in eine ressourcenschonende und lebenswerte Stadt der Zukunft überzuleiten. Dabei fällt auf, dass Smart-City-Initiativen gezielt Kinder und junge Menschen adressieren. Anknüpfend an Ansätze der Gouvernementalitäts- und geographischen Kindheitsforschung gehen wir der Frage nach, wie die nahezu unhinterfragten Glaubenssätze einer von Innovationsoptimismus geprägten Stadt Vorstellungen von Kindheit verändern und ihre gesellschaftliche Inwertsetzung vorantreiben. Wir untersuchen erstens diskursanalytisch, wie Smart-City-Leuchtturmprojekte der EU in die Alltagswelten von Kindern investieren und diese als Experimentierfelder smarter Stadtentwicklung nutzen. Am Beispiel einer Fallstudie des Smart-City-Projektgebiets Wien-Simmering diskutieren wir zweitens, wie der smarte Stadtumbau auf das Alltagsleben von Kindern und Jugendlichen Einfluss nimmt und ihre Bedürfnisse be- und aufgreift. Unsere Ergebnisse zeigen, dass junge Menschen als smarte Bürger_innen in die Pflicht genommen werden, stadtentwicklungspolitische Zielsetzungen mitzutragen und entsprechende Handlungsweisen in ihren Alltag zu implementieren. Dies schafft neue Abhängigkeitsverhältnisse, die kritisch betrachtet werden müssen.

Diabetic Retinopathy (DR) is the complicatedness of diabetes that happens due to macular degeneration among Type II diabetic patients. The early symptom of this disease is predicted through annual eye checkups. Hence, one can save their vision at an early stage. Later on, it prompts retinal detachment. There is a requirement for awareness among diabetic patients about this disease to prevent their life from vision misfortune. Along these lines, there is a need for a computer-assisted method to analyze the disease. The proposed system used Adaptive Histogram Equalization (AHE) technique for image enhancement, Hop Field Neural Network for blood vessel segmentation, and Adaptive Resonance Theory (ART) for blood vessel classification. The proposed system analyzes the disease and classifies the disease level effectively with high accuracy. Also, the system notifies the users about the stages of the disease. The proposed system is evaluated with the clinical as well as open fundus image data sets like DRIVE, STARE, MESSIDOR, HRF, DRIONS, and REVIEW for diabetic retinopathy prediction. Also, physicians evaluated the system and concluded that the proposed system does not deviate from the quality of disease analysis and grading. The proposed techniques accomplished 99.99% accuracy. The system is evaluated by the ophthalmologists and witnesses that the proposed system has not veered off as far as quality.

Risk assessment in manufacturing, construction or service systems are very important tools for ensuring occupational health and safety. Many risk assessment approaches have been proposed in the literature, each with its advantages and disadvantages. In the literature, the authors attempt to develop methods to overcome some of these disadvantages. Different risk priority orders can be obtained for the same failure types with the developed and traditional approaches, and the results may be inconsistent. Hence, different methods produce inconsistent risk ranking outcomes for the same risk assessment problem. This causes confusion for decision-makers when deciding the most-risky failure modes. In this study, the application of the Technique of Precise Order Preference (TPOP) for risk assessment in the field of occupational health and safety (OHS) is conducted to fill the gap in the literature concerning the problem in question and to solve the ranking inconsistency problem related to occupational health and safety. The results of this study show that the advantages obtained from different methods can be combined and a favorable risk priority order can be acquired for decision-makers.

The municipal solid waste compost consists of elements with a varied composition, including light and heavy metal elements. For MSW compost to act as a soil conditioner, and to ensure agricultural stakeholders to believe in its use for crops production, validation of elements is obligatory. The triangular membership function evaluates each element of a fuzzy set for both discrete and continuous values, and regression analysis estimates the relationship between values. In this paper, a triangular membership function (μf) is studied and used to characterize the effect of individual elements available in the compost sample. The characterization determines the variation in the composition of elements in the compost sample and accordingly calculates its scorei. Furthermore, a reinvestigation is done by applying multiple regression analysis, especially on heavy metals, to compare their composition with light mineral nutrients and other supplementary elements. A relationship between R=4.12 and R2=0.067498635 is derived to determine the predicted value and defines the composition of heavy metals as attributed to another mineral nutrients. Furthermore, a correlation (Co) is derived to find the performance of the compost sample todecide whether both light and supplementary mineral nutrients are capable of minimizing the effect of heavy metals. A gratuity score (Gsi) is added to each heavy metal depending on the correlation value to form a composti. The scorei=88.11 and composti = 9.12 obtained, was summated to derive Ci=97.23, stating that the increase in score value declares that the compost sample is mature enough to be used for agriculture and enhance crops productivity.

The extensive use of smartphones by individuals has led innovators to develop application-based transportation services. Ride-hailing systems have been extensively operated in more than 600 cities worldwide. With the competition between taxis and ride-hailing, the number of fleets must be regulated. Identifying factors that influence the demand of taxi and ride-hailing and how the quality transit service is very important. The aims of this research are to identify the factors that influence demand for taxis and ride-hailing and the service quality of taxis and ride-hailing service. The study identified socio-demographic and trip characteristics from 949 respondents in the Jakarta Greater area, Indonesia. Respondents interviewed about the waiting time, travel time and travel costs for the origin-destination of trips that are most often done using taxi, ride-hailing, and bus. The service quality of ride-hailing and taxi was analyzed based on the respondent’s preferences from an important-performance analysis survey. The forecasting demand of taxi and ride-hailing in the Jakarta Greater area using demand-supply model is 71,660 vehicles. The research findings are that service quality of ride-hailing is better than conventional taxis based on waiting time, travel time and travel cost variable.

The mechanical waves have been used as an unconventional enhanced oil recovery technique. It has been tested in many laboratory experiments as well as several field trials. This paper presents a robust forecasting model that can be used as an effective tool to predict the reservoir performance while applying seismic EOR technique. This model is developed by extending the wave induced fluid flow theory to account for the change in the reservoir characteristics as a result of wave application. A MATLAB program was developed based on the modified theory. The wave’s intensity, pressure, and energy dissipation spatial distributions are calculated. The portion of energy converted into thermal energy in the reservoir is assessed. The changes in reservoir properties due to temperature and pressure changes are considered. The incremental oil recovery and reduction in water production as a result of wave application are then calculated. The developed model was validated against actual performance of Liaohe oil field. The model results show that the wave application increases oil production from 33 to 47 ton/day and decreases water-oil ratio from 68 to 48%, which is close to the field measurements. A parametric analysis is performed to identify the important parameters that affect reservoir performance under seismic EOR. In addition, the study determines the optimum ranges of reservoir properties where this technique is most beneficial.

Efficient utilities usage and enhanced heat transfer are imperative in todays’ industrial and technological processes. However, there are several facilities in the nickel industry not upgraded yet. This research studied a hydrogen sulphide production plant with limited heat exchange capacity. Within this context, a neuro-genetic procedure was proposed for optimization of the water flowrates distribution on a hydrogen sulphide gas coolers system. It relied on Genetic Algorithms, combined with an improved ɛ-NTU model for simulation of jacketed shell-and-tube heat exchangers. Artificial Neural Networks were furtherly applied to correlate the optimum water flowrates to predictive variables. The heat transfer incremental was estimated from 3695 to 10514 W, while reduction of the gas exit temperature was projected between 2.9 and 9.8 K. Calculated heat recovery averaged 12.44 %. The optimized water distribution scheme have improved the system energy performance. Applied concept of fixed network and unvaried overall feed water flowrate avoided the additional costs related to topology modifications. A technological solution was provided, consisting on installation of automatic valves and programmable flow control-loops linked to a PLC.

The objective of the study was to establish the influence of utilisation of project budget as a monitoring and evaluation tool and sustainability of community agricultural projects supported by Caritas in Meru County, Kenya. A pragmatic research paradigm was adopted and a descriptive survey research design was utilised. A pragmatic research paradigm was adopted and a descriptive survey research design was utilised. The target population was 59 smallholder farmer groups and 24 Caritas Meru staff. The sample size was 51 smallholder farmer groups and the total sample size was 177 respondents. The data collection tools were questionnaires and interview guides. The collected data were coded and entered into the SPSS version 26 program for analysis. The qualitative data was analysed by way of grouping similar responses together and identifying the main themes from them. The linear regression and Pearson’s correlation (r) methods were utilised to evaluate the link between various variables. The multiple linear regression models determined the link between dependent and independent variables together with the moderating effect of the moderating variable. It is also used as the inferential statistics that inform the decision to reject or not reject the alternative hypothesis for the research study. The study found out that an increase in the utilisation of project budgets leads to an increase in the sustainability of the community agricultural project by Caritas in Meru County and vice versa. The study concludes that there is a significant relationship between utilisation of project budget as monitoring & evaluation and sustainability of community agriculture projects. The study recommends that to ensure the sustainability of community-based agricultural projects, the organisation should train farmers’ group leaders on leadership and management skills. The organisation should train farmers on best farming practices, record keeping and conflict management practices to avoid the collapse of groups.
The Pragmatic Effect of Partial Enantiosemy in a Comic Context
Authors:   Volgograd State Socio-Pedagogical University, Shatskaya Marina F.
Published: November 2021

This article analyses the mechanism of development of evaluative enantionyms in a comic context. The study aims to describe the pragmatic effect created by enantionyms and identify the reasons behind it. The empirical material was selected from the works of the following modern writers: S. Dovlatov, A. Snegirev, and E. Popov. The author of this paper observed the transformations of lexical units in the conditions of a language-game and subsequently analysed the obtained data. The following was established: as a result of the occasional use of lexemes and the development of partial enantiosemy within them, the core of the unit of language-game (a type of dicteme) gets marked. This pragmatic focus leads to connotative recoding, which is based on shifting the object of evaluation and/or on the functioning of several evaluation subjects that differ in their point of view on a situation. The most active in this process are lexemes that have a high level of semantic abstraction and a fairly wide combinability and present most general evaluations of objects and phenomena of reality that occupy extreme positions on the axiological scale. This paradigmatic phenomenon is less frequently observed in words that have more concrete meanings and are somewhat limited in terms of their lexical and/or semantic valence. Thus, under abnormal contextual conditions, enantionyms that developed in the course of the abovementioned processes become markers of the core of a language-game unit and take on the qualities of a pragmeme. Thematically, units of a language-game are quite diverse; however, their most frequent axiological characteristic is as follows: the utilitarian values and evaluations of an individual collide with those generally accepted and declared by large groups of people (the state, professional community or other environment).
Anthropological Aspects of the Digital Transformation of Society: Articulating the Problem
Authors:   Northern (Arctic) Federal University named after M.V. Lomonosov, Skidan Ol’ga P.
Published: November 2021

The general logic of the informatization process, its pace and scale are illustrated here based on the analysis of documented solutions and practices of digital transformation in modern Russia (including the Arkhangelsk Region). Covering the spheres of the economy, social life, and public administration, digital transformation alters the social space, actualizes and shifts the focus to anthropological problems. This paper suggests considering the following questions. What is the place of a person in a rapidly changing world? What can be opposed to the deformation of the existential dimensions of personality? What efforts and in what direction should be made to preserve the human nature (humanity) of a person? What is the role of the state, culture, and religion in solving anthropological problems: what tools do they have to solve them? The analysis shows that time has come to take deliberate steps to find answers and solutions. The traditional humanitarian paradigm defines a person as a standard of truth, paving the way for struggle of interests, politicization of all spheres of activity, and the rule of force. Philosophers have been talking about the limitations of this paradigm throughout the last century, as the established new European approach demonstrates the reality of the “death of the human”. The author suggests turning to the idea of achieving spiritual maturity, transformation, and improvement of a person. This idea rests on the thousand-year-old Russian Orthodox culture. Russian philosophers focused on it for a reason: being based on the values that formed the archetype of Russian people, the idea of internal (and, first of all, moral) transformation of a person has great potential. Today, however, it is poorly understood and rather underestimated. Considering this idea within the framework of the nation state–culture–religion triad and implementing it could be of great benefit, becoming a compensatory mechanism for solving anthropological problems of the digital transformation of society.

Collecting fish morphology data in the field is usually difficult and time consuming. The method of digital photography with further computer processing is currently widely used in biology and facilitates the acquisition of morphological data of fish. The article gives recommendations for obtaining high-quality digital photographs of fish, which we have tested empirically on a large ichthyological material. The studies of the morphological variability of fish following these recommendations showed several positive aspects: accelerating the collection of morphological material, increase of the accuracy of the data obtained, organizing the material in the form of a data bank, the ability to repeatedly refer to a photograph of an object, and a quick exchange of material.

Review question / Objective: P: Patients with AML or MDS after allo-SCT; I: Hypomethylating agents after allo-SCT; C: Observation after allo-SCT; O: Overall survival rates. Condition being studied: Hypomethylating agents (HMAs) seem to have a range of properties favorable to post-allogeneic hematopoietic stem cell transplantation (allo-SCT) maintenance in acute myeloid leukemia (AML) patients. This meta-analysis was performed to review all relevant studies to compare the outcomes of patients undergoing allo-SCT for AML or MDS receiving HMA maintenance therapy with observation only. Information sources: The systematic search of the Embase and MEDLINE databases identified 4,416 articles, from which 512 duplicates were removed. This resulted in 3,904 articles available for title and abstract review. Subsequently, 3,875 articles were excluded as the article type and study design did not fulfill the inclusion criteria, or there was no report on a primary outcome of interest. The remaining 29 articles underwent full-length review and 18 of those were excluded for the aforementioned reasons. Ultimately, the eligibility criteria for our meta-analysis were met by 11 studies: 2 RCTs, 1 prospective cohort study, and 8 retrospective cohort studies.
