Authors: Wazed Md. Abdul , Islam Md. Rakibul 
Published: April 2021

Abstract
People suffering from the celiac disease have to apply a strict gluten-free diet because this is the only effective management. Nowadays, the increasing incidence of celiac disease promotes worldwide interests for various desirable gluten free products. As a consequence, food processing researchers have been seeking to develop high-quality gluten-free bread. Cereals having gluten such as wheat must be removed from the diet for the clinical and histological improvement. So, the purpose of this study was to determine the physical, chemical and sensory properties of gluten-free bread produced with barley (T1), corn (T2) and rice (T3) flours instead of wheat flour, using the 1.5 % xanthan gum. The chemical and sensory attributes of bread were evaluated by AOAC method and hedonic test, respectively. Obtained results showed that sample T3 had the highest contents of crude protein (7.94%), ash (2.51%) and carbohydrate (78.31%) as compared to other samples, while fat was lower (2.01%). Regarding moisture, breads prepared with the three different flours were not statistically different at the significance level of p<0.05. However, they differed significantly regarding the specific volume and bake loss. Data also revealed that gluten-free bread, treatment T3 presented the best parameters, being preferred by the sensory evaluation panel, followed by treatment T1 and T2. The overall assessment pointed that the resulting breads treatment T3 was best for all physico-chemical characteristics and, in general, resulted in good sensory behavior, indicating that it could be a promising alternative to wheat flour.
The impact of educated migrants and R&D expenditures on innovation
Authors: Sinoi Elena-Alexandra 
Published: April 2021

Abstract
Migration has become a topic of great interest of the 21st century, as it triggers multiple advantages and downsides, both for the people and communities implicated, depending on the policies in place. International migration should not be perceived as an issue that needs to be solved, but rather a global phenomenon that can reduce poverty and foster inclusive growth and sustainable development, both in origin and destination countries. The most highly-skilled immigrants represent a key factor in enhancing innovation and technological change processes, which are essential aspects of social and economic development. The purpose of the study is to analyse the impact of highly educated immigrants (with tertiary-educated immigrant employees and foreign PhD students) together with R&D investments on innovative activity (proxied by the number of patents applications), in the case of the ten countries which joined the EU in 2004. The evaluated time frame is from 2011 to 2017. For the econometric analysis of the panel data, we developed fixed-effects linear regression models, at the country-level. The indicators computed are relevant to the innovative activity. The econometric estimations highlight a positive correlation between educated migrants and the number of patent applications in all ten countries. This nexus is even strengthened when we take into consideration other relevant impact factors, such as investments in R&D and human capital. Therefore, the more efforts and investments are devoted to R&D and highly educated individuals, the more predictable the innovation is.

Authors: Jovković Biljana , Vasić Aleksandra S. , Bogićević Jasmina 
Published: April 2021

Abstract
Dividend policy is one of the most controversial areas of corporate finance. The paper presents the results of the research in the banking sector of the Republic of Serbia. The specific characteristics of the financial sector make the research on dividend policy determinants additionally complex. This study aims to determine the factors of dividend policy in the Serbian banking sector in the period 2009–2018. The model of random effects was chosen to test the relationship between dividend determinants and dividend payout. Empirical results show that previous years’ dividends have a significant positive effect on dividend policy. Individual investors can benefit from the research to a great extent, as well as bank managers, when creating dividend policies that would contribute to maximising profit and satisfying the needs of employees and shareholders in the long run.
Les plaies de la Grande Guerre dans la Berliner Illustrirte Zeitung, un imaginaire de papier sous la République de Weimar
Authors: Zunino Bérénice 
Published: April 2021

Abstract
Après l’armistice, la Première Guerre mondiale continue à être traitée dans la revue illustrée d’actualité générale, politique et culturelle qu’est la Berliner Illustrirte Zeitung (BIZ). Sur la trace de cette médiatisation de la guerre, nous interrogeons ce que ces représentations « disent » des attentes, des peurs et des espoirs des contemporains progressistes de Weimar. Il ressort qu’après avoir diffusé une certaine bienveillance à l’égard des anciens ennemis début 1919, la BIZ s’aigrit à la suite de l’officialisation des conditions de paix. Sans doute ces espoirs déçus ont-ils compliqué la démobilisation culturelle de la BIZ, qui continue un temps à se faire le relais du discours de guerre, puis tente par l’expression artistique, tout au long des années 1920, de panser les plaies du deuil. Finalement, la BIZ ne cherche pas tant à entretenir la mémoire de la guerre qu’à promouvoir un discours pacifiste et républicain.
Queer/Race Geographies: Community and the Politics of Difference
Authors: Wong Emily 
Published: April 2021

Oppression is a concept which has been extensively examined in feminist and anti-racist geographies. Many people are engaging with anti-oppressive activism and politics, and are getting involved in challenging systems of domination. However, as resistance is also influenced and produced through systems of oppression, those who practice anti-oppressive politics are still under the influence of those systems. This research project explores the nature of how oppression may be replicated within communities which claim to be anti-oppressive.
For many queer people of colour, locations where community is found also become locations of exclusion. Using the framework of the politics of difference, the construction of community is examined in relationship to difference on the grounds of race and gender/sexual identity, in addition to how social positionality is negotiated and experienced. Constructions of community involve the act of drawing borders, defining proximities, and creating distance between people; it is a necessarily geographical concept. The experiences of people who are both queer and racialized are explored through the use of qualitative interviews, providing insight into how patterns of oppression play out and how processes of human differentiation take place. Demarcating a “community” necessarily involves processes of inclusion and exclusion; that is, who constitutes the community, and who is placed outside of it. For many queer people of colour, locations where community is found also become locations of exclusion.
The Strength of Steel: Nationality and Power within Trinidad Carnival Music
Authors: Palleschi Aisling 
Published: April 2021

This paper discusses how steelband music within Trinidad carnival simultaneously enhances and confuses feelings of national identity. In my current research exploring politics and power in Caribbean carnival music, steel pan has proven to be a strong case study, providing compelling illustrations of the issues surrounding ethnicity, social and economic class structures, politics, and nationalism. The music of steel pan began as a lower-class, ‘grass-roots’, “vulgar, underclass pastime” (Dudley 2007: 3). To the elite citizens, steelband music threatened the social hierarchy and because the laws that society attempted to regulate banning the steel music dissolved, they believed the music would break down the class structures they tried hard to solidify. As it evolved, however, steelband music became gentrified, cleaned up by the elite classes of Trinidad. Through this evolution it can be interpreted that since the upper-class
citizens could not rid Trinidad of steel pan, they therefore attempted to ‘improve’ the image of steel so it could be accepted into society. Steelband has progressed since then to become a national and political instrument, used now to both affirm a political agenda and compete with it. By exploring an art form defined as a national instrument by Trinidad I show that a comprehensive study of how the development of the music can give insight into the problems and benefits of nationalism, identity, and tradition.

Percutaneous vertebroplasty for symptomatic osteoporotic compression fractures: A single–center prospective study
Authors: Ahsan Md. Kamrul , Pandit Om Prakash , Khan Md. Shahidul Islam 
Published: April 2021

Background:
Osteoporotic vertebral compression fractures (OVCFs) increasingly occur with advancing age, and are associated with significant morbidity, mortality, and cost. We assessed the clinical efficacy, radiological, and functional outcomes for patients undergoing percutaneous vertebroplasty (PVP) due to OVCFs, with a special focus on the frequency of new vertebral compression fractures (VCFs).

Methods:
This study, carried from 2018 to 2020, included 22 females and 4 males. They averaged 60.15 years of age (range, 50–70) were followed an average of 14.5 months (range 12–36 months), and had 30 VCFs between the T7–L2 levels. Multiple variables were studied, including; anterior vertebral height (AVH) and kyphotic angle (KA), new VCFs, and functional outcomes.

Results:
The postoperative Visual Analog Scale and Oswestry Disability Index were significantly reduced at 12 months after PVP. Improvements for AVH and KA were also statistically significant; 23 patients (88.46%) had a dramatic decrease in pain on post-operative day 1, while 3 patients (11.53%) had no decrease in pain after PVP on post-operative day 1–1 postoperative month. No major complications were observed except high incidence of cement leakage at 8 levels (26.67%) in 6 patients. Additionally, new VCFs occurred in 10 vertebrae in 8 patients (30.76%), involving 6 adjacent (60%), and 4 nonadjacent vertebrae (40%).

Conclusion:
PVP is an effective procedure in the management of painful OVCFs refractory to medical treatment. These PVP procedures yield immediate vertebral stabilization, relieve pain, and restore function with minimal associated morbidity.
Societal return on investment may greatly exceed financial return on investment in neurotechnology-based therapies: A case study in epilepsy therapy development
Authors: DiLorenzo Daniel John 
Published: April 2021

Background:
This research study is an economic analysis of a neurotechnology-based translational research and development venture focused on the development of a therapy for patients with epilepsy. In the conceptualization, planning, financing, and execution of neurotechnology ventures, many factors come into play in determining value and ability to secure financing at each stage of the venture. Conventionally, these have included factors that determine the return on investment for the stakeholders of the venture, most notably the investors and the team members, the former investing hard earned capital, and the latter investing significant portions of their professional careers. For a variety of reasons, the positive impact on society is often not quantified and taken into consideration.

Methods:
To address this, a new term is defined and assessed at a first approximation level using an index technology. The metric is termed the societal return on investment (sROI).

Results:
Among chronic conditions, neurological disease is virtually unique in the magnitude of economic devastation that it can inflict on a person and a family. Because the device costs do not reflect this value that is lost and subject to restoration, these are missing from this important calculation. The index project is the development of a seizure advisory system, which cost $71.2 million to develop and conduct a First-In-Man (FIM) study (NCT01043406) and which was estimated to require $50 million to complete a pivotal study.

Conclusion:
Despite the immense costs required to develop, test, and commercialize such a system, the direct and indirect economic costs imposed by uncontrolled seizures are sufficiently staggering that a sROI becomes positive after only 400 patients have been successfully treated and returned to work.
Intracranial pressure waveform changes in Alzheimer’s disease and mild cognitive impairment
Authors: Ribeiro Estela Barbosa , Cobos Luiza D’Ottaviano , Rabelo Nicollas Nunes , Frigeri Gustavo , Vale Francisco Assis Carvalho 
Published: April 2021

Background:
Alzheimer’s disease (AD) is known to cause an enormous impairment to the quality of life and impact in the health system; meanwhile, studies show that in the coming years, the number of affected individuals will continue to grow. It is also believed that amnestic mild cognitive impairment (MCI) could represent an early symptomatic form of AD, which precedes dementia.

Methods:
The present study aimed to evaluate the intracranial pressure (ICP) through a noninvasive method in patients with AD and MCI, seeking for differences when compared to healthy elderlies. This is a cross-sectional, correlational, and observational study of a quantitative character, carried out in a Brazilian city, with patients from the ANEC of the UFSCar.

Results:
It was found a statistically significant difference between the ICP morphology when analyzing the results in patients with AD and MCI, compared to healthy volunteers. It is known that dementias means a progressive disorder that leads to the loss of independency and function of the patient, although, it is believed that it can be found early ICP alterations in these patients. Nevertheless, considering this is an unprecedent study, it was not possible to compare results with previous studies and literatures. However, the study has a limitation related to the sample size; an expansion of it could possibility lead to different findings.

Conclusion:
The findings through the ICP measurement could indicate an early diagnosis, which would lead to an early treatment and an improvement in the quality of life of patients with AD. Thus, further investigation and widening studies are encouraged.
Cryptococcal meningitis presenting as anterior spinal cord syndrome with accessory nerve palsy in immunocompetent patient: A case report
Authors: Cuellar-Hernandez J Javier , Seañez Carlos , Olivas-Campos Ramon , Chavez Rodrigo , Tabera-Tarello Paulo M. , Serna-Roman B. Manuel 
Published: April 2021

Background:
Cryptococcus has a tropism for the nervous system with a higher prevalence of infection in immunosuppressed patients; it remains a major cause of human immunodeficiency virus (HIV)-related mortality worldwide. Neurological compromise caused by this microorganism mainly debuts as a meningeal syndrome, spinal involvement has been reported in literature, neuropathological assessments have found Cryptococci in spinal roots and meninges, with perineuritic adhesions probably explaining compromise lower cranial nerves and even spinal nerve roots.

Case Description:
39-year-old male seronegative for HIV, with a surgical history of hydrocephalus treated with ventriculoperitoneal shut 1 year before, he presented with progressive weakness in the four extremities evolving to be disabling with bilateral accessory nerve palsy and loss of sensation below his neck. The MR imaging showed diffuse leptomeningeal thickening both supra and infratentorial and over the spinal canal up to C5 with a cystic formation shown in the craniocervical union causing compression of the medullary bulb. The patient underwent a medial suboccipital craniectomy with resection of the posterior arch of c1 for sampling and decompression, pathologically appears numerous spherical organisms that have a thick clear capsule and are surrounded by histiocytes forming a granuloma compatible with Cryptococcus. Postoperatively, the patient’s prior neurological deficits resolved.

Conclusion:
It is an infrequently suspected pathology in immunocompetent patients, usually requiring only antifungal treatment with adjustment of immunosuppressive or antiretroviral management. In special and rare situations like our case as presenting with lower cranial nerve and spinal involvement, surgical treatment is a priority for the resolution of the pathology and improves disabling neurological deficit.

Teamwork during the COVID-19 Pandemic
Authors: Lajčin Daniel , Porubčanová Dáša 
Published: April 2021

The essential of presented paper is human resource management, especially the concept of teamwork in home office conditions, for which both the state and the private sector of the Czech Republic were not used before the declaring a state emergency to prevent the spread of COVID-19. The presented paper has a classical structuring of the scientific paper, it is divided into a theoretical part and an empirical part. The theoretical part of the paper is based on a critical analysis of relevant information sources, which we have chosen with regard to the topic of the paper and the timeliness of the information provided in the information source. To synthesize and generalize the outputs of the critical analysis of information sources, we used a procedure from general to specific. In the empirical part of the presented paper we apply the information obtained to teams from the private sector and teams from the public sector. Using a questionnaire survey, we compare these two groups of teams in the areas of the concept of teamwork, team functionality, team management by its leader and motivation to perform in the context of the preparedness of the analyzed teams for home office. We found that greater negativity of teamwork as less productivity, or more demanding communication, is perceived by people from a private sector. Increased work from home in the private sector has improved communication and, in the public sector, work efficiency. In public sector, there is more frequent work control and feedback.

The Advantages and Disadvantages of E-working: An Examination using an ALDINE Analysis
Authors: Beňo Michal 
Published: April 2021

Objectives: Working remotely comes with significant pros and cons with different demands for individuals or teams. E-working has been the object of much interest, but there has been little research on the statistical difference between its advantages and disadvantages. Research Question: Is there a significant statistical difference between them? Methods: The present research, however, goes one step further and identifies the statistical difference between them. Firstly, we evaluated the positive and negative aspects with a meta-analysis of 20 studies and, secondly, we used a non-parametric test, namely the Wilcoxon Rank Test, for further analysis across pros and cons. Findings: We found that e-working provides more positive than negative ones. A binomial test showed that most studies (more than 50%) mention flexibility, productivity and efficiency, satisfaction and WLB as benefits. Novelty/improvement:E-working is a triple win option. There are many advantages to working remotely, but this method of work does not suit everyone. Our results provide building blocks for a more complete theoretical and practical treatment of e-working for the future. But COVID-19, technology advancement and a connected global world show clearly that e-working will play a crucial role in the future of the workplace. Doi: 10.28991/esj-2021-SPER-02 Full Text: PDF
Q-H characteristics for heavy crude oil pipeline
Authors: Кутуков Сергей Евгеньевич , Четверткова Ольга Витальевна , Гольянов Андрей Иванович 
Published: April 2021

Проблема повышения точности технологических расчетов нефтепроводов обрела особую остроту на фоне модернизации системы обнаружения утечек и разработки программного обеспечения в области планирования грузопотоков в системе магистральных трубопроводов. Расхождение результатов гидравлических расчетов и фактических параметров перекачки вызвано, в частности, такими факторами, как игнорирование мультифазного характера течения нефти (особенно на недогруженных участках нефтепроводов, проложенных по пересеченной местности), отсутствие актуальных данных по состоянию длительно эксплуатируемых труб, применение методик расчета потерь энергии на трение, базирующихся на постулатах классической гидравлики. В настоящей статье авторами предложен метод определения гидравлической характеристики трубопровода на установившемся режиме эксплуатации, перекачивающего неньютоновские реологически сложные нефти в диапазоне малых скоростей сдвига, который предполагает непосредственную интерпретацию экспериментальных данных вискозиметрии и исключает погрешности аппроксимации кривой течения реологической моделью и осреднения параметра вязкости. С этой целью рассмотрены вопросы аномалии вязкости и тиксотропии неньютоновских нефтей. Дано обоснование предлагаемого метода и представлено практическое приложение излагаемой методики на примере анализа гидравлической характеристики магистрального нефтепровода Атырау-Самара, по которому транспортируется смесь нефтей с частично разрушенной внутренней структурой.
The problem of improving the accuracy of technological calculations for oil pipelines has become especially acute against the background of modernization of the leak detection system and development of software in the field of planning cargo flows in the trunk pipeline system. Discrepancy between hydraulic calculation results and actual pumping parameters is caused, in particular, by such factors as ignoring the multiphase oil flow nature (especially in under-loaded sections of oil pipelines laid over rough terrain), the lack of up-to-date data on the state of long-operating pipes, the use of methods for calculating friction-related energy losses based on the postulates of classical hydraulics. In this article, the authors propose a method for determining the hydraulic characteristics of a pipeline at steady state operation, pumping non-Newtonian rheologically complex oils in the range of low shear rates, which implies a direct interpretation of experimental viscometry data, excluding errors in approximating the flow curve by a rheological model and averaging the viscosity parameter. For this purpose, the anomaly of viscosity and thixotropy of non-Newtonian oils are considered. The article provides a substantiation of the proposed method and presents a practical application of the described technique by the example of the analysis of the hydraulic characteristics of the Atyrau-Samara main oil pipeline, through which an oil blend with partially destroyed internal structure is transported.
