Conflicts Between Farmers and Conservationists: The Role of Communication in the Management of Natural Resources
Authors: Meierová Tamara
Published: September 2020

The importance of communication in conflict situations between conservationists and farmers about problems related to agricultural practices such as erosion, biodiversity loss, and water quality has been highlighted frequently. However, in the Czech Republic, there is a very limited amount of scientific data about this issue. This article presents a literature review summarising evidence on how conflicts between farmers and environmentalists proceed; steps that can be taken to achieve progress in face-to-face communication and there is also a case study of a specific collaborative partnership from a small parish in South Moravia that focuses on improving natural values. Recommendations on how to build more constructive dialogue and develop cooperation between various groups are analysed, and principles that enhance dialogue and may contribute to overcoming disagreements through partnership are indicated. The collaborative partnership in the case study involves a farmer working together with a municipality and other stakeholders on a local level to improve nature conservation and ecosystem services. The majority of the general principles of collaboration and communication for conflict resolution that were identified in the literature review were fulfilled; nevertheless, the partnership currently has limited outreach as the two agribusiness companies which manage the majority of the land in the parish have not been included.

Transient Natural Convection in Partitioned Enclosures
Authors: Zemani Farah , Sabeur-Bendehina Amina
Published: September 2020

In this paper, the natural convection flow in a cavity heated differentially with a partition placed in the middle of the hot wall is numerically simulated. The aspect ratio of the geometry, Prandtl number are fixed at 0.24, 6.64, respectively, for different partitions lengths; however the Rayleigh number values were ranging from 106 to 3.77 × 109 in order to observe the transition regime. The fluid flow and the heat transfer described in terms of continuity, linear momentum and energy equations were predicted by using the finite volume method. To approach the physical reality experience, calculations were performed in a cavity with the same size and same priority of the fluid with an average temperature T

m
imposed on the cooled wall, also another simulation with an average temperature T

m
imposed on the horizontal wall.

Time evolution, isotherms and mean Nusselt number are presented for all investigated values. Representative results illustrating the effects of the partition length for the heat transfer and the thermal boundary layer are also reported and discussed. The results indicate that the flow and heat transfer properties are altered by the presence of the partition, especially in the initial stage. In a certain sense, the partition blocks the flow and forces it to come off the hot wall. Since the partition parameters are critical for the transient natural convection flow in the cavity, different partition lengths on the warm wall have been studied.

Published: September 2020

Ahmed Body is a standard and simplified shape of a road vehicle that's rear part has an important role in flow structure and it's drag force. In this paper flow control around the Ahmed body with the rear slant angle of 25° studied by using the plasma actuator system situated in middle of the rear slant surface. Experiments conducted in a wind tunnel in two free stream velocities of U = 10m/s and U = 20m/s using steady and unsteady excitations. Pressure distribution and total drag force were measured and smoke flow visualization carried out in this study. The results showed that at U = 10m/s using plasma actuator suppress the separated flow over the rear slant slightly and be effective on pressure distribution. Also, total drag force reduces in steady and unsteady excitations for 3.65% and 2.44%, respectively. At U = 20m/s, using plasma actuator had no serious effect on the pressure distribution and total drag force.

Experimental Determination of the Surface Geometrical Structure Parameters and Tool Wear During Turning the Polymer Concrete
Authors: Kępczak N. , Rosik R.
Published: September 2020

The paper presents the results of experimental determination of the Surface Geometrical Structure (SGS) parameters and tool wear during turning the polymer concrete. Until now, all literature reports have shown that the smoothness and roughness of the mineral cast surface was obtained directly from the mold. However, new applications of polymer concrete, even for some parts of the machine tools, forced the producers to carry out machining, which would improve the parameters of the surface layer. The topic of machining ceramic-based composite materials is a new chapter in the field of machining, which has not been sufficiently researched so far. The article describes the process of experimental determination of dependence of surface layer and tools wear parameters from cutting parameters during longitudinal turning of polymer concrete. The turning was carried out using plates made of a cubic boron nitride (CBN). After machining, the surface roughness and the maximum width of the flank wear were measured. On this basis, the mathematical model of the surface layer and tools wear parameters versus cutting parameters were defined. The authors also attempted to explain the phenomena occurring in the machining zone using variable cutting parameters. Microscopic pictures of CBN plates after machining were also performed. After the study, the final conclusions about the machining of mineral cast material were formulated.

Authors: Koutu Vaibhav , Dhakar Rajesh , Ojha Pragya , Shastri Lokesh , Malik M.M.
Published: September 2020

As TiO2 is suitable for electronic and electrical applications, in the present work the authors have successfully modified TiO2 by adding silver (Ag) to form titanium oxide-silver oxide (TiO2:Ag2O) nanocomposite samples by using sol-gel technique. Characterizations of these composites have been performed using X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM) and UV-Vis spectroscopy. XRD study revealed that the crystal structure of the samples consisted of tetragonal and cubic phases. This study further showed an increment in the average crystallite size from 8 nm to 38 nm with an increase in Ag concentration. The increase in crystallite size has been confirmed additionally by SEM and AFM. The increment in the average particle size of the samples may be attributed to an increase in silver molarity in the TiO2 matrix. Significant red shift in the absorption edge has been observed, causing reduction in the energy bandgap of the composites from 3.89 eV to 3.46 eV with an increase in particle size which is evident from UV-Vis spectroscopic studies. This wide-band gap properties of the TiO2:Ag2O nanocomposite make it suitable for memory-storage devices and dielectric applications.
Structural and morphological characterizations of pure and Ce-doped ZnO nanorods hydrothermally synthesized with different caustic bases
Authors: Ait Abdelouhab Z. , Djouadi D. , Chelouche A. , Hammiche L. , Touam T.
Published: September 2020

This investigation concerns the synthesis as well as structural and morphological characterizations of pure and Ce-doped ZnO nanorods. The samples were synthesized by simple low-temperature hydrothermal process using respectively NaOH and KOH as caustic bases. The as-synthesized nanorods were characterized in terms of their morphological, structural, compositional and vibrational properties. The sizes of the rods were found to be 1.5 μm to 2 μm in length and 250 nm to 300 nm in diameter. The presence of Ce ions in ZnO (NaOH) favored the agglomeration of the rods to form flower-like nanostructures. EDAX measurements showed Zn rich materials with high oxygen vacancy concentration. XRD results indicated that the synthesized ZnO nanorods possess a pure wurtzite structure with good crystallinity. It has also been found that Ce doping deteriorates the crystalline quality of ZnO (NaOH) and improves that of ZnO (KOH). The insignificant intensities observed in FT-IR signals confirm that the synthesized nanorods are of high purity. The Raman spectroscopy studies showed that Ce ions shift the vibrational modes towards lower frequencies. The peaks related to E2 (high) mode in ZnO (KOH) are relatively intense compared to those of ZnO (NaOH). The peaks are found to be shifted and asymmetrically broadened due to anharmonic effects originating from quantum-phonon-effect confinement.
“Our ladies” versus “our dominators”: Gender differences and nationalist discourse in the Polish Olympic coverage
Authors: Organista Natalia , Mazur Zuzanna , Dóczi Tamás
Published: September 2020

The article presents differences in describing sportspeople during the last four Olympic Games in terms of gender and nationality in Polish newspapers. The fundamental goal of the research was to perform the quantitative and qualitative comparison of press materials from four Olympics (Vancouver 2010, London 2012, Sochi 2014, Rio de Janeiro 2016). The content analysis was used for the quantitative part of the study and critical discourse analysis of two newspapers (the broadsheet and tabloid) in Poland for qualitative part. 712 media articles were analyzed. Our analysis has revealed significant underrepresentation of women and also differences in the description of rival competitors as well as overrepresentation of articles about Polish representatives during the Olympics. Those articles dwelt on the issue of nationality much more often and were more emotionally charged. Also, to a great extent, the performance of non-Polish women athletes was left unconsidered. The authors therefore indicate the validity of combining gender analysis and nationality in the context of the Olympic Games.
Drive unit characteristics of a completely electrical passenger aircraft
Authors: Fąfara Jean-Marc
Published: September 2020

Aviation has, over the years, become an inseparable element of human life. Airplanes are very commonly used for various tasks, such as transport of passengers and goods, military attack and defence, rescue, recreation and so on. In spite of the many advantages of aviation, one cannot ignore its disadvantages. The most important disadvantages of aviation are the emissions that cause atmospheric pollution and noise. Additionally, one should remember about the decreasing stocks of non-renewable fuels. These drawbacks affect human health and the natural environment. Therefore, a good alternative to conventional drive units in aircraft may turn out to be electric drive units in the near future. The aim of this article is to check the extent to which today’s knowledge and technology allow the use of electric drive units instead of conventional aircraft drive units. This article presents the concept of electric aircraft, from the electric drive unit to its power supply system. The feasibility of designing an electric jet drive unit for a passenger aircraft was analysed based on the performances of PZL 104 Wilga 35 and Boeing B787 Dreamliner.

Authors: Nicol John Leslie
Published: September 2020

This study considers solid planets at about 300 K and an inert atmosphere having no interaction with associated radiation. Processes considered include transfer of energy from the surface skin to underlying layers depending on thermal properties. Temperatures of the surface depend on the rates of transfer of energy between soil layers. The atmosphere is warmed at base by contact with the surface, convection and turbulence distributing higher temperatures through the air. Comparisons between theoretical and measured temperatures show a close similarity. Mean planetary temperatures are calculated, depending on thermal parameters and the intensity of light/radiation from the particular solar system.
МОТИВ vs МОТИВ ЯК ІНТЕРДИСЦИПЛІНАРНИЙ ФЕНОМЕН ТА ФІЛОЛОГІЧНА ПРОБЛЕМА
Authors: Заоборна Марія
Published: September 2020

Стаття репрезентує новий виток осмислення диз’юнктивної опозиції термінів, яку утворюють мотив як аспект текстового наративу та мотив як волютивний феномен. Відповідно окреслюється традиційне літературознавче трактування мотиву як елемента оповіді та смислового повтору й актуалізується мовознавчий потенціал мотиву як психологічного конструкта, в контексті якого мотив розглядається як етап породження тексту та лінгвістична семантико-прагматична текстова категорія. На цьому тлі пропонується інтегроване представлення виділених літературознавчої та лінгвістичної категорій засобом їх усвідомлення у привативній та еквіполентній опозиціях. У результаті розглянутий під лінгвістичним радикалом мотив як оповідний феномен визначається як предикативно організована одиниця оповіді, смисловий повтор у тексті, що в семіотичному плані матеріального втілення корелює з використанням системи семантичних, синтаксичних та прагматичних лінгвальних засобів означування. З іншого боку, імплантована в площину літератури лінгвістична категорія мотиву конкретизується як пов’язаний з особистістю автора (наратора), авторською манерою й типом письма позамовленнєвий феномен, що стосується маркованого лінгвальними корелятами психологічного боку текстотворення як аспекту мовленнєвої діяльності та усвідомлюється як імпульс до створення тексту. Врешті, окреслені в еквіполентній опозиції спільні ознаки літературознавчої та лінгвістичної категорій формують перспективу для осмислення мотиву як власне філологічного феномена, сутність якого становлять лінгвально марковані, зумовлені певною ситуацією усвідомлені чи неусвідомлені стани автора (наратора), в яких актуалізуються пов’язані з особистісними смислами моделі мислення, що слугують розгортанню сюжету й повторюються в парадигмі текстів певного автора, типу письма, літературного напряму, епохи. Загалом же застосований інтегральний підхід увиразнює ситуацію зустрічного руху, який сьогодні переживають літературознавство й лінгвістика.

From the history of studying the Koibal dialect of the Khakass language
Authors: Kaksin A. D.
Published: September 2020

The article gives a general view of the modern Koibal dialect of the Khakass language. The history of studying Koibal speech includes several stages. In the 18th and early 19th centuries, the first evidence of the people living at the mouth of the Abakan River and their language, was collected. Some interesting records were made by G. Miller, P. Pallas, G. Spassky, some other scientists and travelers. Comparing the people under study with other peoples inhabiting the Minusinsk Hollow at that time allowed defining quite a large number of peoples in this area (including Koibals) to be Samoyeds speaking languages with one common property: these are different versions of the Turkic type language. In other words, in that period already, the assimilation of Samoyeds languages by Turkic languages was underway. The article then provides an assessment of the main work of an outstanding Finno-Ugrist and Altaist Mathias-Alexander Castren in linguistic Turkology − a brief grammar of Koibal and Karagas dialects (published in 1857), with notes made by the prominent orientalist Nikolai Katanov to the text by Kastren taken into account. In the second half of the 19th and 20th centuries, the information on the Koibal dialect and other linguistic formations of this part of Southern Siberia was systematized by L. P. Potapov, N. A. Baskakov in the Khakass-Russian dictionary (1953) and an essay by S. I. Weinstein. Later, when the study of South Siberian languages was put on a serious scientific and organizational basis, the Koibal dialect, like other territorial varieties of the Khakass language, was described in sufficient detail by V. G. Karpov, M. I. Borgoyakov, D. F. Patachakova, O. P. Anzhzhanova, in Grammatik and the Khakass-Russian dictionary (2006). Finally, some lexical and grammatical phenomena in modern Koibal dialect are considered, and a scheme (model) of language interaction that resulted in the Koibal dialect of the Khakass language is introduced.

Drug Addiction: Current Trends and Management
Authors: Singh Jyotika , Gupta Pradeep Kumar
Published: September 2020

Drug addiction has become a worldwide problem and the leading cause of death. The global problem of addiction and drug abuse is responsible for millions of deaths and millions of new cases of HIV every year. In recent years, India is seeing a rising trend in drug addiction. The most common use of drug in India is alcohol, followed by cannabis and opiates. Drug use, whether licit or illicit, causes serious health problems in individuals. The National level survey conducted on drug use in India indicated that prevalence of drug abuse among males in the general population is significant. Drug abuse among women exists. Despite the fact that more men use drugs than women, the impact of drug use tends to be greater on women, because women lack access to care for drug dependence. Economic burden, disturbed family environment, violence, and psychological problems are other consequences of drug abuse in the family. Adolescent drug abuse is another major area of concern because more than half of the person’s with substance use disorder are introduced to drugs before the age of 15 years. At present, there exists a significant gap in service delivery. The current paper highlights the causes of drug abuse, and describes the treatment and prevention of drug abuse and addiction for proper management of the problem.

Happiness Experiences and Transformation in Yoga and Spirituality Practitioners
Authors: Kandi Suneetha
Published: September 2020

Indian Psychology (the applied aspects of Indian Philosophy) has withstood the test of time. In one sense, it is more ‘scientific’ than actual science because the theories of science have been proved and then disproved, in light of new inventions and discoveries, but those of Indian psychology as postulated in yoga psychology texts have not been negated and continue to thrive. Another reason for these Truths to be still relevant is the fact that many of them can be validated by the experiential knowledge and individual personalized experiences of the people who adopt them. Ānanda or happiness/bliss is one such concept. In this paper an attempt is made to discuss the personal narrations of the experience of happiness. The results of this study indicated that this ānanda or rather traces of this everlasting ‘imperishable’ happiness, is experienced while on the path and it results in transformation of the individual. This study on ānanda experiences can lend support and throw new light on happiness and positive psychology.

Authors: Alkhalifah Khaled , Asbeutah Akram , Brindhaban Ajit
Published: September 2020

Objectives:

The aim of this study was to determine the optimum combinations of target and filter materials for various X-ray tube voltage settings, as well as their effects on image quality and radiation dose. This was done using different digital mammography (DM) imaging systems with a breast equivalent phantom.

Material and Methods:

Two DM units with a tungsten (W) target, silver (Ag), and rhodium (Rh) filters and dual molybdenum (Mo) and Rh targets/filters were used. A tissue-equivalent mammography phantom of 6 cm thickness equivalent to a fibrofatty breast was exposed 20 times to different target/filter material combinations (W/Rh, W/Ag, Rh/Rh, Mo/Rh, and Mo/Mo) and various kV settings (28–34 kV). The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated for each exposure.

Results:

The W/Ag combination resulted in the lowest entrance skin dose and mean glandular dose (MGD). The MGD for the W/Rh combination was 60% less than that of the W/Ag combination at 34 kV (P < 0.05). There was a direct relationship in the SNR with the Mo/Mo, Mo/Rh, and Rh/Rh combinations and an inverse relationship with the CNR in the 34 kV range. There were statistically significant differences between all five target/filter combinations, and the best SNR and CNR were observed for the W/Rh combination with a reduced radiation dose in the range of 28–30 kV (P < 0.05).

Conclusion:

For a breast thicknesses of 6 cm with a fibrofatty nature, the W/Rh combination delivers high performance in terms of image quality at a lower dose.

Published: September 2020

The space of modern education is voluminous. It is so capacious that it can accommodate any number of different educational systems. On the one hand, these are systems of pre-school, General, and vocational education, which in turn include subsystems of the basic level (primary, secondary, and higher professional education, etc.). On the other hand, and this point is discussed in the article, the concept of “educational space” covers not only the system parameters of the largest integrated education system in the scale of society (city, region, country, world), but also other characteristics that make it possible, based on the analysis of their state, structure and dynamics, to speak convincingly about the directions and quality of development of socio-cultural relations in General.

Authors: Braun Dominik , Eiser Maximilian , Puntscher Hannes , Marko Doris , Warth Benedikt
Published: September 2020

Breast milk substitutes, e.g. infant formulae, are commonly introduced to the diet within the first months of life. As the infants detoxifying capability is not fully developed, it is of vital importance to minimize their exposure to food contaminants. Here, we present a comprehensive multi-mycotoxin assessment in infant food. Samples from the Austrian and Czech market (n=59) were screened for 46 mycotoxins and key metabolites using two complementary LC-MS/MS methods. Trace levels of 17 mycotoxins, including aflatoxin B1 (0.4 µg/kg), zearalenone (<2.3 µg/kg), deoxynivalenol (<131 µg/kg) and fumonisin B1 (<39 µg/kg) were detect-ed. Infant formulae were contaminated at lower levels compared to cereal-based products. Overall, the concentrations of most toxins were near or below their respective LOQ value. However, two raw flour samples exceeded the regulatory limit of aflatoxin B1 for infant foods. Interestingly, two toxins not reported previously, namely aflatoxicol and sterigmatocystin, were identified in 3 and 17% of infant foods, respectively.

The influence of the polymer solubility on the separation efficiency in thermal field-flow fractionation (ThFFF) was investigated for a polymer model system of differently branched chain walking polyethylenes in five different solvents, which were selected depending on their physical parameters. The understanding of polymer thermal diffusion has been elucidated using a revisited approach based on the latest thermal diffusion prediction model by Mes,

Kok and Tijssen combined with the Hansen solubility theory. Thereby, a significant improvement in the precision of the thermal diffusion prediction and the separation efficiency has been achieved by implementation of the temperature dependency on Hansen solubility parameters. In addition, we demonstrate a method for validation of the segmental size of polymer chains with varying topology by using the revisited thermal diffusion prediction approach in inverse mode and experimental thermal diffusion data.

This study presents CryptoChem, a new method and associated software to securely store and transfer information using chemicals. Relying on the concept of Big Chemical Data, molecular descriptors and machine learning techniques, CryptoChem offers a highly complex and robust system with multiple layers of security for transmitting confidential information. This revolutionary technology adds fully untapped layers of complexity and is thus of relevance for different types of applications and users. The algorithm directly uses chemical structures and their properties as the central element of the secured storage. QSDR (Quantitative Structure-Data Relationship) models are used as private keys to encode and decode the data. Herein, we validate the software with a series of five datasets consisting of numerical and textual information with increasing size and complexity. We discuss (i) the initial concept and current features of CryptoChem, (ii) the associated Molread and Molwrite programs which encode messages as series of molecules and decodes them with an ensemble of QSDR machine learning models, (iii) the Analogue Retriever and Label Swapper methods, which enforce additional layers of security, (iv) the results of encoding and decoding the five datasets using CryptoChem, and (v) the comparison of CryptoChem to contemporary encryption methods.

Despite their remarkable charge carrier mobility when forming well-ordered fibers, supramolecular transistors often suffer from poor processability that hinders device integration, resulting in disappointing transconductance and output currents. Here, a new class of supramolecular transistors, π-ion gel transistors (PIGTs), is presented. An in situ π-ion gel, which is an unprecedented composite of semiconducting nanofibers and an enclosed ionic liquid, is directly employed as an active material and internal capacitor. In comparison to other superamolecular transistors, PIGT displays a high transconductance (133 µS) and output current (139 µA at -6 V), while retaining a high charge-carrier mobility (0.16 cm2 V-1 s-1) and on/off ratio (3.7*104). Importantly, the unique device configuration and the high ionic conductivity associated with the distinct nanosegregation enable the fastest response among accumulation-mode electrochemical-based transistors (< 20 µs). Considering the advantages of the absence of dielectric layers and the facile fabrication process, PIGT has great potential to be utilized in printed flexible devices. The device platform is widely applicable to various supramolecular assemblies, shedding light on the interdisciplinary research of supramolecular chemistry and organic electronics.

DC-SIGN multivalent antagonists have emerged as effective antiadhesive agents against various pathogen infections. Recently, our group have shown that high potency can be achieved upon bridging two of the four binding sites displayed by the protein. Here we present our endeavors to accomplish the tetracoordination of DC-SIGN through the synthesis of two cross-shaped glycodendrimers. The choice of a tailored rigid scaffold allowed multivalent presentation of glycomimetics in a spatially defined fashion, while providing good water solubility to the constructs. Evaluation of the biological activity by SPR assay revealed strong binding avidity towards DC-SIGN and increased selectivity over langerin.
Predicted 3D Models of the SARS-CoV-2 Spike Protein Membrane Proximal External Region and Transmembrane Domain
Authors: Izvorski Alexander
Published: September 2020

The transmembrane helix domain (TMD), membrane proximal external region (MPER) and part of heptad repeat 2 (HR2) domain in SARS-CoV-2 spike protein were modelled using a constrained fold-and-dock strategy. The resulting structures were clustered and their large scale pose variability and energy landscape is described; several representative models are discussed. The results suggest considerable flexibility in the conformation of those regions, which may have an important role in the ability of spike protein to fuse the cell and viral membranes.
Chromium–Salen Complex / Nitroxyl Radical Cooperative Catalysis:A New Combination for Aerobic Intramolecular Dearomative Coupling of Phenols
Authors: Nagasawa Shota , Fujiki Shogo , Sasano Yusuke , Iwabuchi Yoshiharu
Published: September 2020

Herein we describe an aerobic intramolecular dearomative coupling reaction of phenols using a catalytic system with the combination of a chromium–salen (Cr–salen) complex and a nitroxyl radical. This novel catalytic system enables the construction of a spirocyclic dienone product, which is a potentially useful intermediate for the synthesis of various natural products such as alkaloids and phenylpropanoids from bisphenol in good yield under mild reaction conditions (under O2 and ambient temperature). A preliminary mechanistic study suggests that this reaction system is promoted by a cooperative electron transfer between the Cr(III)–salen complex, nitroxyl radical and bisphenol substrate.

Published: September 2020

The formation processes of metal-organic frameworks are becoming more widely researched using in-situ techniques, although there remains a scarcity of NMR studies in this field. In this work, the synthesis of framework MFM-500(Ni) has been investigated using an in‑situ NMR strategy that provides information on the time-evolution of the reaction and crystallization process. In our in‑situ NMR study of MFM-500(Ni) formation, liquid-phase 1H NMR data recorded as a function of time at 5 fixed temperatures afford qualitative information on the solution-phase processes and quantitative information on the kinetics of crystallization, allowing the activation energies for nucleation and growth to be determined. Ex-situ SAXS studies provide complementary nanoscale information on the rapid self-assembly prior to MOF crystallization and in-situ powder X-ray diffraction confirms that the only crystalline phase present during the reaction is phase-pure MFM-500(Ni).
