Cow’s Milk Protein Allergy in Term and Preterm Infants: Clinical Manifestations, Immunologic Pathophysiology, and Management Strategies
Authors: Burris Amy D. , Burris Jonathan , Järvinen Kirsi M.
Published: December 2020

Cow’s milk allergy is a common food allergy among infants. Symptoms of cow’s milk allergy are wide-ranging and depend on the mechanism involved. There are immunoglobulin E (IgE)-mediated, non–IgE-mediated, and mixed mechanisms of food allergy. Symptoms of IgE-mediated cow’s milk allergy may be mild or may progress to anaphylaxis, which can be life-threatening. Non–IgE-mediated allergy includes food protein–induced allergic proctocolitis (FPIAP), food protein–induced enterocolitis syndrome, food protein–induced enteropathy, and Heiner syndrome (pulmonary hemosiderosis). These diagnoses comprise about half of all cow’s milk allergies. The most common manifestation of cow’s milk allergy in infants is FPIAP. FPIAP is commonly seen in healthy, full-term infants who present with rectal bleeding and are otherwise well-appearing. This can occur in both formula-fed and exclusively breastfed infants. Food proteins secreted in maternal breast milk can contribute to the development of these symptoms. Maternal cow’s milk elimination diet is often successful in helping resolve symptoms. A period of reintroduction of cow’s milk resulting in re-emergence of symptoms in stable asymptomatic infants is an excellent diagnostic tool to confirm a cow’s milk allergy. Preterm infants are susceptible to food allergy, as demonstrated from several case reports of necrotizing enterocolitis–like illnesses that responded clinically to cow’s milk elimination. Further study is needed about food allergy in the preterm infant population.

Authors: Yasmin Tahira , El  Refae Ghaleb A. , Eletter Shorouq
Published: December 2020

This paper highlights that oil price fluctuations cast negative impact on oil exporting economies of Caspian Basin namely as; Azerbaijan, Kazakhstan and Russia. These resource abundant economies faced revenue contraction and dwindling budget expenditures due to oil price change. To justify underlined reasons, current study examined export and economic diversification analysis for all three economies. It can be concluded that these countries unable to achieve economic diversification due to over dependence on oil revenues. Most of the export oriented sectors consists of minerals, oil and gas by neglecting the more sustainable growth of non-resource tradable sectors. As a result, these countries have huge share in exports mainly as natural resources. In terms of economic diversification which is based on sectoral value added also indicates that these countries are showing some signs of diversity but still  there is need to have structural reforms and policy instruments to diversify their revenue stream.
The econometric model for assessing the economic category of a Russian farmer entrepreneur in terms of the "Innovator vs. Conservative" system
Authors: Semin Alexander , Kislitskiy Mikhail
Published: December 2020

The slowdown in agricultural growth in Russia determines the development of an innovation base for expanding exports. Therefore, the formation of a new social class of farmers-entrepreneurs, focused on the implementation of innovative activities, becomes relevant. The aim of the study was to develop an econometric model for assessing the economic types of farmers-entrepreneurs according to the system “innovator versus conservative” using the example of the agro-industrial complex. The questionnaire method was used to determine the levels of innovative development of the respondents. The survey was conducted from October 2017 to December 2019; 900 farmers from Tver, Kursk, Tambov, Penza, Arkhangelsk, Kurgan, Leningrad regions, as well as Yakutia took part in it. Using the method of cluster analysis, all classes (categories) of farmers-entrepreneurs are determined by the level of innovation. Depending on the type of enterprise, classification functions of farmers have been developed

Authors: Setiawan Haris , Maliza Rita , Maulana Syaiful Adam , Hisbullah Muhammad Ilham
Published: December 2020

Coffee fruit skin contains antioxidant compounds that can repair damaged tissues, especially those of reproductive or-gans. This study was designed to assess to what extent the metha-nolic extract of coffee fruit skin affected sperm characteristics and testicular histology in mice receiving 15% ethanol for 15 days. It used 25 male mice aged four months and employed a completely randomized design with two controls (K) and three treatments (P), namely K1 (without ethanol), K2 (15% ethanol), P1 (15% ethanol and the methanolic extract of coffee fruit skin, or MECS, at 125 mg/ kg BW), P2 (15% ethanol and MECS 250 mg/kg BW), and P3 (15% ethanol and MECS 500 mg/kg BW). These treatments were administered orally with a 1 mL disposable syringe for 15 days. The parameters observed were sperm characteristics (viability, morphology, and sperm count) and the microscopic structure of the testicles (lu-men area, diameter, and area of seminiferous tubules). These data were then analyzed using the one-way ANOVA, continued with the LSD and Duncan’s tests (P <0.05). The results showed that P2 (250 mg/kg BW) substantially improved sperm count (86.5x105±1.73 cells/ mL), sperm viability (87.26±0.05%), and the proportion of normal sperm morphology (93.33±0.004%) of mice with 15% ethanol-in-duced sperm damages. Testicular histology also confirmed improve-ments in spermatogenic cells, as evident from the lumen, diameter, and area seminiferous tubules after receiving P1 and P2. In conclu-sion, the optimum dose of the coffee skin extract for improving sperm quality and microscopic structures of mice testicles is 250 mg/kg BW.

Published: December 2020

The response to the challenges arising during the COVID-19 pandemic has seen the rapid implementation of innovative technological solutions which have been built on established knowledge and resources. This has been reflected in infection, prevention and control practices (IPC) to minimise the transmission of the disease. In this article, we review ultraviolet germicidal irradiation (UVGI) as such a technology. We illustrate the way it has traditionally been used in airborne and surface disinfection strategies, and how it has, more recently, been adapted. UVGI has been widely used as an environmental IPC measure against tuberculosis in South Africa, though challenges have been experienced in the implementation of the technology in public healthcare facilities. This has resulted in the development of a knowledge and infrastructure base. We posit that, given the established UVGI resources in South Africa, the technology may be a viable environmental IPC solution for the COVID-19 period and beyond.

Published: December 2020

In March of 2020, South Africa responded to the global COVID-19 pandemic by instituting a full lockdown. This meant that only essential services were allowed to operate, causing schools, universities and workplaces to close. The University of Cape Town was about to complete its first term when this occurred. With campuses closed, students were asked to vacate residences and return home. The university went into emergency remote teaching, with all teaching and learning moving online. Students were provided with the necessary resources to access content via the university learning platform, but strict guidelines were set to ensure that the delivery of content was not data or bandwidth intensive. For our master’s-level course on Health Innovation and Design, this posed many challenges. Health Innovation and Design is part of the curriculum for the MPhil in Health Innovation and the MSc in Biomedical Engineering. It utilises design thinking methodologies as an approach to innovate for improvements in health and wellbeing. The course comprises group-based action learning with a project partner and endeavours to promote engaged scholarship (UCT, 2020) by interacting with constituencies outside the university for public good. For 2020, we had secured the provincial Department of Health as our project partner. Our students were going to work with a team on designing and developing an operating theatre information system for scheduling. We would have had our first hospital visit the week after the university closed its on-campus activities.

The review considers a general theoretical model of nanoparticles similar to the structure of a "green walnut", consisting of a core, a surface and a layer of ligands. Due to the peculiarities of such a surface defect structure in nanoparticles, the phenomenon of high-temperature ferromagnetism in the nonmagnetic parent structure is possible (considered by the example of semiconductor metal oxides, noble metals, and carbon nanostructures). It is shown that this phenomenon is not of an artifact nature, but is possible for any materials in a highly dispersed state. The main reasons for the cooperative magnetic effect in the system of defect-induced magnetic moments are proposed. The review also discusses the ferron model, which is successfully used to analyze the properties of modern magnetic nanomaterials.

La forja del imperio ultramarino. El sistema defensivo y la vida soldadesca en los presidios del Gran Caribe en el siglo XVII: caso de la guarnición de La Habana
Authors: Reichert Rafal
Published: December 2020

El siglo XVII, en el ámbito de la historia colonial, se presenta como una época de constante lucha de la corona española para conservar su predominante posición en Europa. Esta situación tuvo sus repercusiones en las tierras americanas que, a partir de la guerra con la Inglaterra isabelina, se convirtieron en la frontera imperial de la monarquía hispana. Por eso, España creó un sistema defensivo contra la amenaza extranjera. Con ello se emprendió un gran proyecto de construir y modificar fortificaciones en las Indias, sobre todo en la región del Gran Caribe, donde para mantenerlas se necesitaban recursos humanos y monetarios. En este artículo, mediante historiografía y fuentes primarias de archivos de España y México, se presenta el aspecto de la soldadesca española que sirvió en los presidios grancaribeños. Se presentan los aspectos de reclutamiento para las Indias, la vida cotidiana y, además, con el ejemplo de La Habana, se analiza la precedencia originaria de los soldados indianos

Authors: M. Gyazova Marina , D. Vlaznev Igor
Published: December 2020

Aircraft Maintenance, Repair and Overhaul (MRO) is one of the major components of the Aircraft Life Cycle Cost (LCC). Increasing the efficiency of MRO, as well as reducing MRO cost, is one of the main ways to reduce LCC. In modern aviation technology complexity of Avionics and its maintenance increase. Traditional methods of failure prediction are difficult to apply in complex technical systems which make it necessary to reduce MRO interval. This research proposed the mathematical method of Artificial Neural Networks (ANN) as a possible solution to this problem. The avionics of Unmanned Aerial Vehicle (UAV) is the research object. The reliability and forecasting of failures by traditional and ANN methods have been analyzed, and results comparison are received. The study suggests that the method used is suitable for solving this problem. The obtained results show a high degree of reliability. Further research is proposed to scale to more complex avionics aircraft. The introduction of ANN in the MRO system entails many advantages, including the possibility of increasing the avionics service intervals and failure prediction, taking into account external factors of operation. This will inevitably lead to LCC reduction and increase safety.

Development of a Promising Area of Diversification in Helicopter Industry
Authors: V. Krivolutsky Yuriy
Published: December 2020

Many countries have main pipeline systems that deliver hydrocarbon deposits from fields to their places of consumption and for export. Pipelines during operation require constant maintenance, industrial safety monitoring, repair, and protection. An accident there entails significant loss of product, additional financial costs, tangible environmental damage, and, in some cases, loss of life. To prevent it, it is necessary to use various types of monitoring, including aerospace. In addition to existing control methods, unmanned aerial vehicles (UAV) of a helicopter type with a long flight range can become a modern high-tech tool for solving problems of monitoring main pipelines. For a helicopter manufacturing enterprise, this is a new perspective area in diversifying its production and commercial activities.

Writing and Implementing an Open Textbook in World Regional Geography: A Case Study
Authors: Finlayson Caitlin
Published: December 2020

As the rising cost of college textbooks has outpaced both inflation and increases in tuition fees, this expense has created a significant barrier to student learning. Some instructors have adopted or created open educational resources, meaning materials which are freely and openly available. While the most obvious benefit of open course content might be cost savings, the fact that these materials can be freely adapted and changed can have substantial impact on the learning experience itself and enable an instructor to completely change the structure and outcomes of a course. This paper provides a case study on writing an open textbook for a course called World Regional Geography and details the writing process and platform options. I also offer practical guidance for faculty interested in authoring open materials and insight into how writing open materials might be framed in terms of a faculty member’s larger portfolio of professional activity.
Internationalizing Professional Development: Using Educational Data Mining to Analyze Learners’ Performance and Dropouts in a French MOOC
Authors: Chaker Rawad , Bachelet Rémi
Published: December 2020

This paper uses data mining from a French project management MOOC to study learners’ performance (i.e., grades and persistence) based on a series of variables: age, educational background, socio-professional status, geographical area, gender, self- versus mandatory-enrollment, and learning intentions. Unlike most studies in this area, we focus on learners from the French-speaking world: France and French-speaking European countries, the Caribbean, North Africa, and Central and West Africa. Results show that the largest gaps in MOOC achievements occur between 1) learners from partner institutions versus self-enrolled learners 2) learners from European countries versus low- and middle-income countries, and 3) learners who are professionally active versus inactive learners (i.e., with available time). Finally, we used the CHAID data-mining method to analyze the main characteristics and discriminant factors of MOOC learner performance and dropout.
Implementing Mobile Learning Within Personal Learning Environments: A Study of Two Online Courses
Authors: Bidarra José , Sousa Nuno
Published: December 2020

This article presents a case-study of two distance learning courses, in order to address the question of universal adoption of mobile devices and applications by students, and the impact of these devices in personal learning environments (PLEs). First, a critical discussion of the value of these concepts in the current technological context was carried out, followed by an analysis of their impact on educational use, based on data collected in online courses on physics and statistics at Universidade Aberta, the Portuguese Open University. The results indicated that all students have adopted mobile learning, and the make-up of an individual’s PLE depends more on the learning resources available rather than on gender or age. These findings can help provide more efficient ways to implement learning by connecting current social needs to learners’ mobile PLEs, particularly when flexibility of time and space are of utmost importance. Further studies at the Portuguese Open University will address a larger and more balanced sample of students across more course units.

Authors: CORSINI ANNA , ZACCHEO PATRIZIA , CRIPPA LAURA , MANACHINI BARBARA
Published: December 2020

The nematofauna was studied in the early stages of a remediation trial at an industrial site where pyrite cinders had accumulated for 40 years in a large area and were then covered with mineral soil. The cinders were contaminated with several metals and metalloids. The soil of the experimental plots was derived from the mixture of cinders with the covering soil in a 1:1 ratio. Plots were amended with manure and sown with 3 metal resistant plants: Sorghum bicolor L., Helianthus annuus L., and Arundo donax L. Samples were taken : a) at the beginning of the trial on the pyrite cinders and covering soil, separately; b) from the mixture before the application of manure; c) from cultivated plots. Nematode communities were compared by using general composition, trophic structure, biodiversity and ecology indices. Nematofauna and other soil fauna were not detected in the pyrite cinders. Nematodes were recorded in the covering soil and after mixing with the cinders. In these early stages of the remediation process, amending and cropping increased nematode abundance and biodiversity compared to the initial situation of the pyrite cinders. The nematode community structures and all calculated indices showed an increase in the quality of the soil after the remediation process. Our results showed that phytoremediation brought about the repopulation of an extremely compromised area.
