NATIONAL SELF-PRESERVATION OF UKRAINIANS IN THE CONTEXT OF THE MODERN FESTIVAL MOVEMENT IN POLAND
Authors: Bosak Edgar
Published: July 2021

The article is dedicated to the consideration of the Ukrainian festival movement in Poland in the third decade of Ukraine 's independence in the context of national self-preservation. The paper substantiates the social and political reasons for the relevance of preserving the national self-identification of Ukrainians in Poland. Attention is paid to the legal basis of this aspect of Ukrainian-Polish relations and to the current statistics on the number of Ukrainians in Poland. The author proposes a conditional division of the Ukrainian festival movement in Poland according to its direction into «festivals of national preservation» and «festivals of cultural exchange» depending on the goals, participants and program of events. The characteristics of the most important public organizations that provide the cultural needs of the Ukrainian national minority are presented: the Association of Ukrainians in Poland, the Union of Ukrainians of Podlasie, the Lemko Association, etc. Attention is drawn to the role of the mass media as an important factor in popularizing information about festivals and consolidating the Ukrainian people scattered throughout Poland. The newspaper «Nashe Slovo» («Our word») is considered to be the most influential information resource and at the same time a source of research on the issue. The article analyzes the problems of sources of funding for the Ukrainian festival movement, focuses on significant financial assistance from the Polish government, administrations of gmins, powiats and Voivodeships, as well as private foundations. The author describes the development and features of the most famous Ukrainian-Polish festivals in Poland till 2021. The features of these events and some changes in their activities caused by recent events are shown: Russia's military aggression against Ukraine in 2014, the coming to power in Poland party «Law and Justice» and the COVID-19 pandemic. The latest editions of Ukrainian festivals in Poland are presented, the most famous bands and artists that took part in them are listed. Among the current problems of these cultural events are the aging of the organizers and the departure of socially active youth to large cities or abroad. Based on quantitative and qualitative indicators, the author making tha accent on the growing influence of the Ukrainian festival movement in Poland in 2014 − 2021 compared to the previous decade.
THE TREASURE IN TRADITIONAL HUTSUL’S BELIEFS OF HISTORICAL-ETHNOGRAPHICAL TRANSCARPATHIA (BY THE FIELD MATERIALS)
Authors: Korol Vasil
Published: July 2021

In this article, based on the significant quantities collected by author filed materials, archive and literary sources in traditional hutsul’s beliefs the treasure of historical-ethnographical Transcarpatia is considered. The traditional submission was revealed and the motive of a treasure finding and its main displays traced. The attention was focused on existence of two types of treasures “clear” in folk tradition, that is hidden without an appropriate charming, anyone could take them without harm to yourself and «unclear», which are under unclear force’ protection. The methods of protection and charms from possible harmful consequences of obtaining the ordered treasure were considered. Found out that the main of such beliefs dating back to antiquity and remnants of the archaic world-view of hutsuls with a set of different in meaning and origin of the phenomena of ancient and modern tradition. A dark force guards the traditional beliefs disclosed, which are disseminated in the Carpathians for the treasure. In particular, among hutsuls of historical-ethnographical Transcarpathia, the owner instructs to guard the treasure he buried in the ground for the domestic and demonic character. The current status of preservation and living traditional submission about treasure and related with it magical actions have been studied. The legends widespread in Transcarpathian Hutsulschyna are still spread today, as evidenced by the stories of first-person informants. Even today, the traditional beliefs hutsuls of Transcarpathia are characterized by apparent identity and conservatism due to the natural and geographical conditions, remote from urban centers.

TUHAN, NABI, DAN NEGARA IDEAL "Telaah Atas Pemikiran Al-Farabi"
Authors: Yamani Gasim
Published: July 2021

This article aims to explore the realms of al-Farabi's philosophical thought, by focusing on four problems: Is God unnecessary in the process of creating nature to know, think and even make nature the object of his thought? 2). How to interpret the influence of Imagination that underlies al-Farabi's theory of prophethood? 3). How is al-Farabi's view of the human soul? and 4). What is the ideal state form for al-Farabi? To answer this problem, the method used is library research research, with a philosophical approach. The research results obtained: First, God does not depend on nature as the object of his thought in the process of natural creation. Second, the Prophet, through his strong imaginative abilities, was not only able to deal directly with Mustafad's intellect, but was also able to translate the revelations that were sent down and transferred to us. Third, the soul has two powers, a theoretical power, namely the human thinking power that can distinguish and judge and is able to express different competences, and the practical power is the power that determines what human actions must be done. Fourth, the ideal country is a country whose leader is not only political, but also includes ethical issues.

Authors: Yamanoglu R. , Fazakas E. , Ahnia F. , Alontseva D. , Khoshnaw F.
Published: July 2021

This study aims to investigate the influence of adding a coating layer of austenitic stainless steel type 316L on Ti6Al4V alloy on corrosion behaviour. Samples of 316L, Ti6Al4V, and 316L on Ti6Al4V were prepared by hot-press sintering of their powders. The potentiodynamic polarization technique was used to characterize the corrosion behaviour of the samples in 0.9 and 3.5 wt. % NaCl concentrations. The corrosion potential (Ecorr.), current density (icorr) and corrosion rate (CR) of the sintered samples were compared in this study. The results showed that 316L samples had the best corrosion resistance, although micropits were observed on the surface, while Ti6Al4V samples had the lowest. This corrosion behaviour of sintered 316L samples can be interrelated to the existence of a passive layer on stainless steel alloys that can be attacked by chloride ions and causing localized corrosion. In general, the CR values of Ti6Al4V samples coated by 316L were between the 316L and Ti6Al4V samples. The CR values of the samples, in 0.9 wt. % NaCl, did not show significant changes with increasing time, as the CR for 316L values were around 0.003 mm/year, while for Ti6Al4V the CR values changed noticeably from 0.018 mm/year of 0 hr, to 0.015 mm/year for 24 hours. However, the changes were less than that of Ti6Al4V. For 3.5 wt. % NaCl solution, although the same order of CR remained, i.e., the CR values of coated Ti6Al4V samples were between 316L (lowest) and Ti6Al4V (highest), the overall CR values for the samples were higher than 0.9 wt. % NaCl.
Multivariate Modelling of Effectiveness of Lubrication of Ti-6al-4v Titanium Alloy Sheet using Vegetable Oil-Based Lubricants
Authors: Trzepieciński Tomasz , Szpunar Marcin
Published: July 2021

The article presents the results of modelling the friction phenomenon using artificial neural networks and analysis of variance. The test material was composed of strip specimens made of 0.5-mm-thick alpha-beta Grade 5 (Ti-6Al-4V) titanium alloy sheet. A special tribotester was used in the tests to simulate the friction conditions between the punch and the sheet metal in the sheet metal forming process. A test called the strip drawing test has been conducted in conditions in which the sheet surface is lubricated with six environmentally friendly oils (palm, coconut, olive, sunflower, soybean and linseed). Based on the results of the strip drawing test, a regression model and an artificial neural network model were built to determine the complex interactions between the process parameters and the friction coefficient. A multilayer perceptron with one hidden layer and eight neurons in this layer showed the best fit to the training data. The network training was conducted using three algorithms, i.e. Levenberg-Marquardt, back propagation and quasi-Newton. Taking into consideration both the coefficient of determination R2 (0.962) and S.D. ratio (0.272), the best regression characteristics were presented by the network trained using the Levenberg-Marquardt algorithm. From the response surfaces of the quadratic regression model it was found that an increase in the density of lubricant at a specific pressure causes a reduction in the coefficient of friction. Low density and high kinematic viscosity of the oil leads to a high coefficient of friction.
Evolutionary origins of music. Classical and recent hypotheses
Authors: Kalinowski Kasper , Kozłowska Agata , Malesza Marta , Danel Dariusz P.
Published: July 2021

The aim of this paper is to review recent hypotheses on the evolutionary origins of music in Homo sapiens, taking into account the most influential traditional hypotheses. To date, theories derived from evolution have focused primarily on the importance that music carries in solving detailed adaptive problems. The three most influential theoretical concepts have described the evolution of human music in terms of 1) sexual selection, 2) the formation of social bonds, or treated it 3) as a byproduct. According to recent proposals, traditional hypotheses are flawed or insufficient in fully explaining the complexity of music in Homo sapiens. This paper will critically discuss three traditional hypotheses of music evolution (music as an effect of sexual selection, a mechanism of social bonding, and a byproduct), as well as and two recent concepts of music evolution - music as a credible signal and Music and Social Bonding (MSB) hypothesis.

Published: July 2021

Stroke is an important health problem generating a set of musculoskeletal and cognitive consequences that significantly affect the patient’s clinical-functional status and quality of life, as well as the effectiveness of the recovery treatment. Hydro-/ thermo-/ kinesio-therapy with water from Lake Techirghiol, known for its special properties, is also used for patients with neurological disorders and consists in immersing the patient in the therapeutic pool with specific exercises under the strict supervision of specialized medical staff. The aim of this study is to analyze the effects of Lake Techirghiol water on the functional deficit in patients with post-stroke sequelae. In this sense, 200 patients who were hospitalized in the Balneal Rehabilitation Sanatorium of Techirghiol, Constanta County, Romania during 2018-2020 were included in the study and they were divided into two groups: patients from group 1 performed on a daily basis, for 12 days, hydro-/ thermo-/ kinesiotherapy and other physical-kinetic procedures, and the patients from group 2 performed on a daily basis, for 12 days, only physical-kinetic procedures, without hydro-/ thermo-/ kinesio-therapy. Patients’ assessment was made based on the Functional Independence Measure scale and a better evolution was observed in the patients who performed hydro-/ thermo-/ kinesio-therapy as compared to those who did not perform this procedure, in the sense of a diminution of the functional deficit by making self-service activities easier and by improving gait disorders and transfers. We consider appropriate that we extend the period of patients’ treatment and follow-up in our next research so as to highlight, if relevant, any notable changes in terms of increasing functional independence also in the case of patients undergoing land-based kinesiotherapy.

Primary pulmonary non-Hodgkin lymphoma is a rare entity, accounting for 3-4% of extranodal non-Hodgkin lymphomas. Indolent primary pulmonary non-Hodgkin lymphomas are the most frequent types, with the MALT subtype representing majority of cases. Other indolent subtypes of B-cell primary pulmonary lymphomas are rare. We present the case of a 56-year-old patient, non-smoker, who presents for pain in the right hemithorax, worsened by deep inhales. Pulmonary X-ray showed a right paramediastinal superior and medial lobe homogenous opacity with faded contour. Thoracic computed tomography scan described a dense right superior mediastino-pulmonary tumoral mass, the absence of hilar or mediastinal adenopathies. In this context, an ultrasound-guided transbronchial needle aspiration was performed. Histopathology and immunohistochemistry confirmed the diagnosis of primary pulmonary small B-cell non-Hodgkin lymphoma. After 6 chemotherapy cycles, from a clinical and imagistic (thoracic CT scan) point of view, the response was favourable. Positron emission tomography (PET/CT) aspect indicated a complete metabolic response to treatment.

Authors: Natera-Rivas Juan Jose , Larrubia-Vargas Remedios , Navarro-Rodríguez Susana
Published: July 2021

The presence of foreigners in the province of Málaga is highly noticeable, especially in specific municipalities such as the city of Málaga, coastal areas, or villages in the Axarquia region. But from a geographical point of view, there are comparatively few investigations dedicated to the definition of the space in which foreign immigrants reside. The aim of this research is to provide a description of the habitats where people who were born abroad tend to concentrate in the province of Málaga. The main novelty of the research is the scale of analysis we have used being intramunicipal, based on Nomenclator statistics. This is especially relevant when we are dealing with small municipalities in some of which the proportion of foreigners is quite high, because it is the only one that allows us to characterise the habitat of the foreigners.
Discrepancies in legal classifications as a hindrance to implementing water policy, on the example of Lake Wysokie
Authors: Dąbrowski Mieczysław , Marszelewski Michał
Published: July 2021

This article deals with the difficulties that arise at the intersection of three areas: the application of law, the need to ensure water environment sustainability, and the need to take into account social interest. The reason behind such a situation is the imprecise lake classification criteria adopted in Polish law. The legal division of lakes has an artificial character and reflects the Polish water management policy, according to which every lake is classified as stagnant or flowing water. This study aims to determine the hydrological type of Lake Wysokie and its legal status, in order to allow proper application of water policy. The methodology included, among others: field hydrological investigations, geodetic measurements, calculation of evaporation and study of historical cartographic documentation. According to the research results, all the features of the lake and its catchment area clearly indicate the standing nature of the waters.

The aim of the article is to substantiate the new concept of special economic zones of Ukraine as stimulating regulatory regimes aimed at attracting innovative investments and developing new industries based on the smart specialisation of regions and trends in the world economy. The regime is presented as a system of incentives and benefits, mandatory conditions and restrictions, and seeks to increase the investment attractiveness and technological diversification of the economy of the regions and the country as a whole. Each component of the regime has been classified, taking into account best practices of other countries and the strategic goals of Ukraine regarding the need to ensure sustainable and innovative development and to enter the world markets as a manufacturer of high-tech innovative products.
Climate therapy and the development of South Africa as a health resort, c.1850–1910
Authors: Rogerson Christian M. , Rogerson Jayne M.
Published: July 2021

Historical research is undeveloped concerning tourism in sub-Saharan Africa. This research contributes to scholarship about the history of tourism for climate and health. In South Africa the beginnings of international tourism are associated with its emergence as a health resort and to climate therapy. Using archival sources an analysis is undertaken of the factors that influenced the emergence of South Africa as a health destination during the 19th century. Climate therapy was of particular interest for the treatment of consumption or tuberculosis. Arguably, the perceived therapeutic regenerative qualities of South Africa's climate became a driver for the development of a form of international tourism that pre-dated the country's emergence as a leisure tourism destination.
Using Spatial Autocorrelation for identification of demographic patterns of Functional Urban Areas in Poland
Authors: Kurek Sławomir , Wójtowicz Mirosław , Gałka Jadwiga
Published: July 2021

Functional Urban Areas (FUAs) leads to a better knowledge of urban spatial organisation, which may play a significant role in regional policy making and may be helpful in understanding the connection between urbanisation and demographic development. An explanation of population change in urban regions can be associated the second demographic transition comprising fertility decline below replacement level and postponement of births.

The aim of this paper is to focus on establishing similarity patterns and anomalous values of selected demographic variables in the cores and peripheral areas of Functional Urban Areas. At the background of this study lies an assumption that population development of FUA's is shaped by different factors connected with second demographic transition and migrations. To achieve the aims the following demographic characteristics were used: population growth rate, dependency ratio, rate of natural increase, the net migration rate, and the dynamic economic ageing index, Spatial methods play an increasingly important role in contemporary socio-demographic research. In order to identify spatial systems Global Moran Statistics and the Local Indicators of Spatial Association (LISA) including Local Moran statistics as well as Getis-Ord Gi* statistics were used.

The research showed global and local autocorrelation of demographic processes in Functional Urban Areas in Poland, namely population growth, natural increase, net migration and population ageing. The use of local Moran's I statistic and the Getis-Ord Gi* method has led to identification of spatial clusters and dispersions representing different demographic variables. Spatial autocorrelation methods can be useful in an analysis of demographic variables including changes in time. The main contribution of this study to the research on demographic processes in urban areas was an application of spatial groupings techniques not only to find out similarity and dissimilarity patterns of demographic indicators but also to apply this findings for the needs of spatial planning.
A New Noisy Random Forest Based Method for Feature Selection
Authors: Akhiat Yassine , Manzali Youness , Chahhou Mohamed , Zinedine Ahmed
Published: July 2021

Feature selection is an essential pre-processing step in data mining. It aims at identifying the highly predictive feature subset out of a large set of candidate features. Several approaches for feature selection have been proposed in the literature. Random Forests (RF) are among the most used machine learning algorithms not just for their excellent prediction accuracy but also for their ability to select informative variables with their associated variable importance measures. Sometimes RF model over-fits on noisy features, which lead to choosing the noisy features as the informative variables and eliminating the significant ones. Whereas, eliminating and preventing those noisy features first, the low ranked features may become more important. In this study we propose a new variant of RF that provides unbiased variable selection where a noisy feature trick is used to address this problem. First, we add a noisy feature to a dataset. Second, the noisy feature is used as a stopping criterion. If the noisy feature is selected as the best splitting feature, then we stop the creation process because at this level, the model starts to over-fit on the noisy features. Finally, the best subset of features is selected out of the best-ranked feature regarding the Geni impurity of this new variant of RF. To test the validity and the effectiveness of the proposed method, we compare it with RF variable importance measure using eleven benchmarking datasets.
A Centralized Model Enabling Channel Reuse for Spectrum Allocation in Cognitive Radio Networks
Authors: Devi Monisha , Sarma Nityananda , Deka Sanjib K.
Published: July 2021

Cognitive Radio (CR) is an advanced technology, which intends to boost the radio spectrum utilization. On perceiving the spectrum holes, next there is a need to provide a fair distribution of the vacant licensed channels amongst Secondary Users (SUs) during the spectrum allocation process. In this context, our paper introduces two allocation models to resolve the spectrum allocation problem. Initially, we design a simple centralized model to assign the channels. Then, we extend it to a centralized fair allocation model that aims to impart a better utilization of the free channels. Both approaches assign a common channel to a group of non-interfering SUs simultaneously. This facilitates spectrum reuse. The constraint related to dynamics in spectrum opportunities in CR is handled during channel allocation. Simulation study analyzes the proposed approaches with an existing allocation mechanism and reveals the performance improvement of centralized fair allocation model in terms of spectrum utilization.

Published: July 2021

This article reviews the methods of safety management using Heinrich’s and Bird’s pyramids. The presence of a causal relationship between pyramid levels, as a result of inconsistencies in the activities of an organization and personnel, lead to incidents, and incidents in turn lead to accidents. The existence of such a relationship makes it possible to predict the risk of “top-level” events by reducing risks at the middle and lower levels. A mathematical description of the development process of an undesired aviation event is presented, which makes it possible to evaluate the probability of the successful (or unsuccessful) completion of a transportation task. Also given is an analysis of the development of an aviation accident, based on the example of the crash of a Lufthansa A-320 aircraft on 14 September 1993 at the airport of Warsaw (Poland) while landing in adverse weather conditions.

Published: July 2021

ABSTRACT

Cinnamon (Cinnamomum burmani) is a spice that can be used as an additive in food and cakes as well as a pharmaceutical ingredient in the pharmaceutical industry. Therefore, the exploration of cinnamon as a natural antioxidant is highly needed. The study aims is to investigate the antioxidant activity of cinnamon using the DPPH, ABTS radical assay and ferric reducing activity power (FRAP) as well as total phenolic and total flavonoids. Cinnamon was extracted using the maceration technique by ethanol 96% as a solvent and tested for antioxidant activity. The antioxidant activity of DPPH, ABTS, and FRAP that showed by the ethanol extract of cinnamon were 1.939 ± 0.055 ?g/mL; 2,235 ± 0.014 ?g/mL; and 1415.705 ± 38.609 mg of ascorbic acid/gram extract, respectively. The antiradical activity of the ethanol extract of cinnamon was lower than vitamin C, namely 0.554 ± 0.003 ?g/mL (DPPH) and 0.813 ± 0.028 ?g/mL (ABTS). The antioxidant activity provided by the ethanol extract of cinnamon was influenced by the total phenolic content and total flavonoids, respectively 75.685 ± 1.408 % EAG and 60,546 ± 0,670% EK. Cinnamon has very strong antioxidant activity, contains high amounts of total phenolic and total flavonoids so that it has the potential to be a food additive (antioxidant) in the food and pharmaceutical industries.
STUDENT CONCERNS FOR ENGAGEMENT IN ONLINE ACTIVE LEARNING ENVIRONMENTS DURING COVID-19
Authors: Memarian B. , Zuluaga S. , Stickel M.
Published: July 2021

This paper shares a summary of the self-reported concerns of 134 first-year engineering students around engagement in online active learning environments during COVID-19. The students had volunteered to participate in remote weekly problem-solving workshops for four weeks that utilized Active Learning techniques. In this paper, we specifically analyze samples from the students who participated in only one workshop and responded to the following question: What concerns do you have that might limit your ability to engage in online active learning environments? Twenty of the participants reported no concerns. The tone of each student's response and personal feelings reported were also analyzed. Then, a thematic analysis of each student response was made, with the transcription and coding agreement being performed by two coders. As expected, most of the students expressed their concerns in a negative or neutral tone, and only a few expressed an affinity for current educational settings. Word mining of feeling terms shows that more students had verbalized being disengaged, followed by distracted and uncomfortable and none communicated a positive feeling. Our thematic analysis showed that learning socially (72/114, or 63%) is the most pressing concern for the students, followed by more personal regulating factors such as attitude and motivation (44%), quality of physical and virtual study environment (40%), as well as the guidance received from the course administrators (24%). Findings suggest the need for developing a global understanding of what active learning in an online environment entails in the context of engineering education, and to develop and adjust tools and practices to help students learn in this new context.
A case report of pregnant lady with hyperemesis gravidarum that led to osmotic demyelinolysis
Authors: Salim Karattuthodi Mohammed , Saidalavi Ramsiya , Fabin Kainadan , Faris Kizhissery Salman , Vijayan Aswathi
Published: July 2021

Background:

The fall of serum sodium concentration may happen in hyperemesis gravidarum and subsequently can result into hypotonic hyponatremia. This would cause water to move into the brain and develop cerebral edema manifested with neurologic symptoms. However, adaptive mechanism by brain would lower the cerebral volume to a normal range. On the other hand, rapid correction of chronic hyponatremia would damage the brain cells. The symptoms depicted because of rapid over correction of sodium is known as osmotic demyelination syndrome.

Case Presentation:

The pregnant lady with hyperemesis gravidarum went to severe hyponatremia. And further, she underwent dilatation and evacuation because of the intrauterine fetal death. The normal saline administered to correct the state of hyponatremia caused the patient to be in depression with catatonia and aphasia. The symptoms were correlated with osmotic demyelinolysis and the event was confirmed with magnetic resonance imaging of brain.

Conclusion:

The administration of sodium should be performed with utmost cautions and under the supervision of well-trained healthcare providers. Any sign or symptom of neurological abnormalities observed because of overcorrection should be considered seriously.

Authors: Tahseen Rabia , Hammad Khan Agha Muhammad , Ahmed Yumna , Ali Nasir
Published: July 2021

Background:

Treatment of locally advanced endometrial cancer in patients with transplanted pelvic kidney requires precautions because of its anatomical position next to target volumes.

Case Presentation:

We report a case of 42-year-old woman with a right renal transplant for 3 years diagnosed with endometrial cancer for which she underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy and pelvic lymphadenectomy. Adjuvant Radiotherapy (RT) was planned through intensity modulated RT (IMRT) with 45 Gy in 25 fractions followed by vaginal brachytherapy (5 Gy × 2 sessions). Planning with IMRT quantified a mean dose of 2 Gy and maximum dose of 10 Gy over the transplanted kidney. This dose was further reduced with a comparative plan of three-dimensional conformal RT (3DCRT), recording a mean dose of 1 Gy and maximum dose of 5 Gy to the transplanted kidney. 3DCRT plan was accepted and delivered. At 2-year follow-up, patient is disease free with normal renal function.

Conclusion:

In the presence of advanced techniques, 3DCRT is still a valid radiation technique to keep the critical organ dose under acceptable dose-volume constraints without compromising the target volume.

In this study, it was aimed to determine some element contents and some quality properties and to compare these parameters at each stage in the chemically refining process of crude corn oil. Color (lovibond tintometer), free fatty acidity, peroxide values and fatty acid compositions were determined in the samples of corn oil taken from consecutive stages of chemically refining. Also, the content of elements (Na, Mg, K, Ca, Fe, Pb, Cd, Ni, Mn, Zn, Co, Cr, P, Cu) was analyzed, by using inductively-coupled plasma-mass spectrometry (ICP-MS) and inductively-coupled plasma-optical emission spectrometry (ICP-OES) after microwave digestion. The color (Lovibond tintometer), free fatty acidity and peroxide values in the chemically refining process varied between 2.7-16, %0.09-2.12, 10.95-1.08 mEqO2/kg, respectively. Oleic, linoleic and linolenic acid contents changed between 30.486-30.580%, 54.339-54.703% and 0.972-0.993%, respectively, in the chemically refining stages. While no trans fatty acids detected in crude corn oil and after degumming-neutralization step, very low amount of trans oleic acid (0.040%) and total trans linoleic acid (0.132%) was detected in bleached corn oil. The total trans fatty acid content little more increased in the last stage of the chemically refining. However, total trans fatty acid content of refined corn oil was < 0.3%. It was clearly seen that Na, Mg, K, P, Ca, Mn, Fe, Pb, Ni, Cr, Cu element contents decreased significantly at the end of the chemically refining process. Although Cd, Co and Zn elements were determined in crude corn oil, these elements were not detected in the refined corn oil. The results obtained showed that the chemically refining process effected some of the quality properties of corn oil and especially the changes in the element contents.

For many seeds, cold press technology generates higher quantities of cakes than seed oils, which are concentrated in proteins. Valorization of the cakes could offer a viable strategy to manufacture protein fortified foods with comparable characteristics as the conventional products. Here, black cumin, grape seed and pumpkin seed protein concentrates were prepared based on an alkaline extraction-isoelectric precipitation technique. The influence of protein concentrate addition on the flour, dough and bread characteristics were investigated for textural profile, gluten quality and visual characteristics including color attributes. While the interactions between gluten and seed proteins were mostly weak, some of the physicochemical attributes differed significantly. In terms of volume and visual characteristics, pumpkin seed protein concentrates enriched bread demonstrated similar characteristics as the controls, while black cumin or grape seed protein concentrate enriched wheat flours were more resistant and less extensible than the controls. Similarities and differences between controls and protein enriched gluten-free or gluten-bearing bread were discussed.

Published: July 2021

This paper examines factors determining farmers‘ adoption decision for improved maize varieties in the maize-common bean intercropping practices in two districts of East Hararghe zone, Eastern Ethiopia. It is based on data collected from 129 farm households using structured questionnaire. Descriptive results revealed that adopters of improved maize varieties had better food and nutrition security status. Furthermore, logit model output indicated that the decision to adopt improved maize varieties is influenced by location (district) dummy, education status of the household head, age of the household head, distance from the main road, and the number of plots owned. Major recommendations include improving the rural road infrastructure, educating and training farmers, organizing experience sharing events among farmers, and raising awareness about the food and nutrition security benefits of sustainable agricultural intensification practices like intercropping improved maize with improved common bean varieties.
1,2-Benzoxathiin-4(3H)-one 2,2-dioxide – an underinvestigated building block with a high synthetic and pharmacological potential: synthesis, chemical properties, biological activity

Aim. To analyze the available literature data on the methods of synthesis, chemical transformations and the biological activity of derivatives containing a sultone core – 1,2-benzoxathiin-4(3H)-one 2,2-dioxide – and to show the possibilities of their further use in the construction of new molecular systems with attractive pharmacological properties.
Results and discussion. The most widespread method for the synthesis of 1,2-benzoxathiin-4(3H)-one 2,2-dioxides is the cyclization of salicylic acid derivatives. The known chemical transformations of 1,2-benzoxathiin-4(3H)-one 2,2-dioxides deal with all reaction centers of the heterocyclic fragment of the condensed system – C=O and CH2 groups, SO2–O bond, CH2CO fragment as a whole. It should be noted that the oxathiine nucleus is prone to undergo recyclizations. The use of 1,2-benzoxathiin-4(3H)-one 2,2-dioxides in multicomponent transformations still remains hardly explored. The “abnormal” course of some classical transformations involving 1,2-benzoxathiine 2,2-dioxides is also noteworthy. The study of the pharmacological properties of 1,2-benzoxathiin-4(3H)-one 2,2-dioxide derivatives is scarce and mainly based on their structural similarity to the coumarin core, which led to the study of anticoagulant, antimicrobial and antitumor properties for the sultone derivatives.
Conclusions. The analysis has shown a limited number of studies in each aspect – approaches to the synthesis of 1,2-benzoxathiin-4(3H)-one 2,2-dioxides, their chemical transformations and the study of their pharmacological activity. In addition to a small number of publications on this heterocyclic system, there have been almost no sultone studies in the last 20 years. Taking this into account 1,2-benzoxathiin-4(3H)-one 2,2-dioxide and its derivatives deserve close attention as objects of research for experimental chemistry and pharmacology.

Research over the past decade has found that the etiology of periodontal disease is a bacterial infection. Efficient ongoing removal of dental plaque is essential, but this may not be enough to completely eliminate the disease. An oral irrigator has been shown to be effective in reducing inflammatory responses associated with periodontal disease for daily use. It has been proven that the daily use of the oral cavity irrigator reduces plaque, concretion, gingivitis, bleeding, and the depth of periodontal probing.
Aim. To investigate the modern assortment of irrigators available at the domestic market, conduct the commodity analysis, study their purpose, design features of these devices and their components, as well as the principles of operation and consumer properties.
Materials and Methods. The informational, retrospective methods, as well as the materials based on research of scientific literature, Internet resources and own conclusions were used.
Results. As a result of the research the authors provided a short historical perspective on the features and necessity of creating devices – irrigators. The current assortment of irrigators, their diversity, purpose, elements of construction, configuration, principles of operation of the device, general technical characteristics have been analyzed. A detailed study of technical characteristics and the comparison of design features of different types of irrigators have been carried out. As a result of the research, it has been determined that this apparatus is represented only by foreign manufacturers at the Ukrainian market. Due to the annual modernization of dental equipment the commodity analysis of irrigators is a hot topic, which must be constantly studied. This will enable modern distributors and pharmacists to thoroughly possess information about irrigators and to bring it to consumers.
