Features of Molding and Structure of Composite Materials Based on TiB/Ti, Obtained by Free SHS Compression Method
Authors: Chizhikov Andrey , Konstantinov Alexander , Bazhin Pavel , Stolin Alexander
Published: August 2020

The work presents the thermodynamic calculations of the adiabatic combustion temperature and the fraction of the liquid titanium phase during the chemical reaction of the initial titanium and boron powders with the initial titanium content from 5 to 80 wt. % during the synthesis of materials based on TiB-Ti. It is shown that with an increase in the preheating temperature of the initial samples to 500 °C, the combustion temperature of the selected composition increases from 3200 to 3600 K, and the fraction of the liquid phase increases from 40 to 80 %. The peculiarity of molding composite materials based on TiB-Ti under conditions combining self-propagating high-temperature synthesis (SHS) and high-temperature shear deformation is studied. These conditions are realized in the method of free SHS compression, which allows synthesizing, molding and obtaining compact material in tens of seconds without using special molds. It was found that the maximum degree of deformation of the synthesized material corresponds to 20-40 wt. % free titanium. For the selected compositions, compact composite materials were obtained by free SHS compression method, the structural features were studied, and the density and porosity of the central and regional parts of the samples were measured.
Numerical Investigation on Key Process Parameters Affecting Blanking of Steel Sheet by Using Finite Element Method
Authors: Sahli Mohamed , Roizard Xavier , Colas Guillaume , Assoul Mohamed , Cornuault Pierre Henri
Published: August 2020

The cutting surface obtained through the blanking process is often characterized by localized plastic deformations followed by crack propagation and ductile failure. The resulting blanked edge is essentially characterized by known areas such as shear zone, fracture zone and also sometimes burr. Their formation depends essentially on various process parameters and cutting material such as punch/die set, punch speed and temperature. The present study was carried out in order to investigate the possibilities for improving the quality of the cut-surface of high-alloy thick sheet steel. It was focused on modeling and analyzing blanking process of steel sheet using finite element method (FEM). The numerical results of the validation simulations were in agreement with the experimental results, thus validating the model parameters used. The model was developed in order to study the effects of process parameters on the blanking of mechanical steel parts, with particular attention to the study of punch-die gap influence.

Published: August 2020

Aloe vera, ginger, and sappan wood have recently gained attention as a potent antioxidant. This study was undertaken to analyze the possible effects of oral administration of herbal infusion (the combination of Aloe vera, ginger, and sapang wood) on fasting blood glucose (FBS) and malondialdehyde (MDA) levels in diabetic rats. Forty male albino rats (150-250 gm) were divided into five groups (n=8 in each group): alloxan-induced diabetic (negative control group/K-), acarbose treated (positive control group/K+), diabetic rats treated with herbal infusion dose 6.75 mg/150 gmbw (P1), diabetic rats treated with herbal infusion dose 13.5 mg/150 gmbw (P2), and diabetic rats treated with herbal infusion dose 20.25 mg/150 gmbw (P3). Male albino rats induced with a dose of alloxan 120 mg/kgbw and also 5% glucose after 6 hours of alloxan induction. FBS and MDA levels of each rat were measured before induction of alloxan was performed as a control sample. After seven days and 14 days of herbal infusion administration, FBS parameters was investigated with a glucometer. In the last week, the concentration of MDA in serum blood was determined using a UV-VIS spectrophotometer with a wavelength of 545 nm. Diabetic rats exhibited a significant decrease in FBS and MDA. Administration of herbal infusion was reduced FBS significantly between groups (ANOVA, Bonferroni, p<0.05). The concentration of MDA in serum blood was decreased significantly on K-, K+, P1, P2, P3 compared to the control group (ANOVA, LSD, P<0.05). It could be postulated herbal infusion has anti-hyperglycemic and anti-diabetic effects of FBS and MDA in male albino rats Wistar strain.

Published: August 2020

Advanced High-strength steels (AHSS) has widely application in automotive due to their high tensile strength and remarkable ductility. These good mechanical performances are strongly influenced by the processing and final microstructure. This paper performed Deformation Dilatometer and finite element simulation to study the effect of hot rolling parameters such as strain, cooling rate, and holding time at constant temperature on the microstructure formation of Nb-V low carbon microalloyed steel grade. It found that increasing deformation degree increased the volume fraction of ferrite, both of deformation dilatometer and finite element simulation give a similar trend of effects of hot rolling parameters on evolution of volume fraction of ferrite. These results give an insight for industrial application.
Philosophers’ debt to their students: The South African case
Authors: Matolino Bernard
Published: August 2020

Philosophy teachers owe their students a little more than mere formal instruction of topics popular in philosophy. What they owe their students is largely influenced by philosophy’s claims to be a discipline that is principally dedicated to the study and fostering of wisdom. Therefore, there is an obligation to be wise on the part of philosophy teachers so that they can deliver that wisdom. A big part of this would involve a sort of transformation in knowledge and character that the teachers themselves must go through as a result of engaging in philosophy. Such transformation will not only show in ways that philosophers live their private lives, as wise people, but will certainly show in the topics they teach their students and how they help their students to wisely respond to their environment through an enlightened, relevant and empowering curriculum. If philosophers fail at this task, they will only dispatch fragmented pieces of information about philosophical topics and method that are of no use to their students. If philosophers are unable to see the shortcomings of this approach, then they can just as well count themselves unfit to be called (wise) teachers but technical philosophers. The fees must fall and Rhodes must fall movement coupled with demands for decolonisation, caught philosophers underprepared for such demands from students. Hence, in this article, I seek to examine the legitimate demands for transformation of the curriculum and how philosophical instruction in the country contributed to this protest, which eventually was caricatured in some sections as unreasonable. I argue that beyond what appears as unreasonable demands by students, there is an obligation by philosophy teachers to be responsible and responsive to the students’ context in what they teach.
Roman Catholicism versus Pentecostalism: The nexus of fundamentalism and religious freedom in Africa
Authors: Enegho Felix E.
Published: August 2020

oday’s Christians in the age of secularism and other kinds of ideologies struggle to make their impacts felt as they assiduously labour to plant the gospel in the hearts and minds of many. Amid their struggles and worries, they are often confronted with other challenges both from within and outside. The aim of this research was to assess the Roman Catholic Church and her struggle in the midst of other Churches often tagged ‘Pentecostals’ in the areas of fundamentalism and religious freedom in Africa and most especially in Nigeria. Pentecostal theology was aligned with Evangelism in their emphasis on the reliability of the Bible and the great need for the spiritual transformation of the individual’s life with faith in Jesus Christ. They emphasise personal experience and work of the Holy Spirit and therefore see themselves as a selected few, who are holy, spiritual and better than others. Some of them even claim to have the monopoly of the Holy Spirit. This researcher was one scholar who holds the view that there was no church more Pentecostal than the Catholic Church which has survived for more than 2000 years under the influence and direction of the Holy Spirit. But for the sake of this research, there was the categorisation of the Church into Catholicism and Pentecostalism. Here, the researcher focused on the challenges to faith witness and evangelisation posed by the rise of Pentecostalism in Africa and particularly in Nigeria. This research adopts a combination of socio-historical and narrative approaches. The data gathering technique was the main source made up of books, unpublished materials, journal articles and Internet materials.Intradisciplinary and/or interdisciplinary implications: The research has relevance to Church History, Dogmatic Theology and Practical Theology. While from the interdisciplinary perspective, the work has relevance in Psychology and other fields in the Social Sciences. The research does not call for a change in traditional discourse, but rather to build on the existing status quo.

The Daniel Ortega’s victory at the Nicaragua presidential election 2016 and perspectives of the construction of the Nicaraguan Channel
Authors: Kolarov Georgui
Published: August 2020

The fourth victory of Daniel Ortega and the Sandinist National Liberation Front (SNLF) (presidential election 2016, Nicaragua) secured a nickname “ the Family” among his close circle and the leadership of the Front. In addition, his in uential spouse, Mrs. Rosario Maurillo, who was nominated for vice-president, received the second most important governmental post. Presidential couple and the leadership of SNLF hold a tight grip on the governance of the country irrespective of fact, that the majority of ex-companions joined opposition and founded the Sandinist Renovation Movement (SRM). Uncompromising position taken by the former “ comandantes” towards ‘’the Family’’ undermines the legitimacy of the ruling party in the eyes of the international community. This, however, cannot in uence the further consolidation of power in the hands of ‘’the Family’’
Mexico: «the population explosion» and mass migration
Authors: Kudeyarova Nadejda
Published: August 2020

The debate over the Mexican migrants issue has been intensi ed by Donald Trump’s election. His harsh statements have provoked a discussion on the US policy for Mexico, as well as on the migration regulation in the United States. However, the mass migration of the last quarter of XX - beginning of XXI centuries may be also readily associated with the social and demographic processes developed in Mexico throughout the 20th century. The dynamics of migratory activity followed the demographic changes. The internal causes of the Mexican migration analysis will allow more clarity in understanding contemporary migration interaction between the two neighboring countries.

Authors: Suwirmayanti Ni Luh Gede Pivin
Published: August 2020

Prodi sistem Komputer memiliki beberapa konsentrasi atau peminatan ketika mahasiswa menginjak semester pertengahan yaitu semester 5. Penentuan konsetrasi ini sangatlah riskan untuk mahasiswa, karena mahasiswa harus memilih sesuai dengan bakat yang ditunjang oleh nilai dari matakuliah pendukung konsetrasi tersebut. Standar dalam menentukan konsentrasi bagi mahasiswa dapat dipengaruhi oleh beberapa faktor, antara lain nilai akdemikyang ditunjukkan dengan nilai matakuliah mahasiswa serta IPK dari mahasiswa tersebut. Penelitian ini bertujuan mengimplementasikan algoritma Self Organizing Map (SOM) untuk clustering konsetrasi mahasiswa. Melihat dari permasalahan utama dari sistem clustering adalah bagaimana membagi sekelompok data yang memiliki kesamaan semirip mungkin ke dalam satu cluster. Metode Self Organizing Map (SOM) pertama kali diperkenalkan pada tahun1981 oleh Prof. Teuvo Kohonen, algoritma ini melakukan proses clustering dengan membentuk jaringan kohonen yang digunakan untuk mengelompokkan data berdasarkan karakteristik serta fitur-fitur dari datanya. Yang dijadikan acuan dasara atau Parameter untuk metode clustering ini adalah nilai-nilai matakuliah di semester sebelumnya, dimana matakuliah tersebut merupakan matakuliah prasyarat . Pengujian dilakukan dengan menguji fungsionalitas sistem, dan mengevaluasi cluster yang dihasilkannya. Hasil nilai cluster yang terbentuk dapat dijadikan sebagai acuan informasi penentu kelompok konsentrasi bagi mahasiswa prodi Sistem Komputer.

Abstract. North African dust reaches the southeastern United States every summer. Size-resolved dust mass measurements taken in Miami, Florida, indicate that more than one-half of the surface dust mass concentrations reside in particles with geometric diameters less than 2.1 µm, while vertical profiles of micropulse lidar depolarization ratios show dust reaching above 4 km during pronounced events. These observations are compared to the representation of dust in the Modern-Era Retrospective analysis for Research and Applications, version 2 (MERRA-2) aerosol reanalysis and closely related Goddard Earth Observing System model version 5 (GEOS-5) Forward Processing (FP) aerosol product, both of which assimilate satellite-derived aerosol optical depths using a similar protocol and inputs. These capture the day-to-day variability in aerosol optical depth well, in a comparison to an independent sun-photometer-derived aerosol optical depth dataset. Most of the modeled dust mass resides in diameters between 2 and 6 µm, in contrast to the measurements. Model-specified mass extinction efficiencies equate light extinction with approximately 3 times as much aerosol mass, in this size range, compared to the measured dust sizes. GEOS-5 FP surface-layer sea salt mass concentrations greatly exceed observed values, despite realistic winds and relative humidities. In combination, these observations help explain why, despite realistic total aerosol optical depths, (1) free-tropospheric model volume extinction coefficients are lower than those retrieved from the micro-pulse lidar, suggesting too-low model dust loadings in the free troposphere, and (2) model dust mass concentrations near the surface can be higher than those measured. The modeled vertical distribution of dust, when captured, is reasonable. Large, aspherical particles exceeding the modeled dust sizes are also occasionally present, but dust particles with diameters exceeding 10 µm contribute little to the measured total dust mass concentrations after such long-range transport. Remaining uncertainties warrant a further integrated assessment to confirm this study's interpretations.
Der späteiszeitliche Tüttensee-Komplex als Ergebnis der Abschmelzgeschichte am Ostrand des Chiemsee-Gletschers und sein Bezug zum „Chiemgau Impakt“ (Landkreis Traunstein, Oberbayern)
Authors: Huber Robert , Darga Robert , Lauterbach Hans
Published: August 2020

Abstract. Anhand von sedimentologischen und
geländemorphologischen Untersuchungen wird die Abschmelzgeschichte des
südöstlichen Chiemsee-Gletschers beschrieben. Mit dem Trockenfallen
der Bad Adelholzen-Erlstätter Rinne im Verlaufe des Spätwürm
entwickelt sich aus dem Abschmelzen des Eislappens in der Grabenstätter
Bucht eine sich ständig tiefer legende konzentrische Abfolge von
zunächst peripheren Entwässerungsrinnen, wobei die ältesten
Rinnen dieser Phase bei Chieming, die jüngeren dann entsprechend weiter
im Süden, in die zentripetale Richtung umschwenken. Die Entstehung des Tüttensee-Komplexes ist im Kontext dieser Entwicklung
zu sehen. Er ist das Ergebnis der glazifluvialen und glazilakustrinen
Sedimentation im Einflussbereich des sukzessiven Eisabbaus in der
Grabenstätter Bucht in Kombination mit einer Toteisbildung im Bereich
des heutigen Tüttensees. Dafür sprechen die stufenartige Abfolge der
beschriebenen peripheren Abflussrinnen mit ihren immer tiefer liegenden
Abflussniveaus, die Höhengleichheit von drei dieser Rinnen mit den
Tüttensee-Terrassen sowie die für die jeweilige Terrassenentstehung
typische glazifluviale bzw. delta-artige Sedimentstruktur und -reife. Dieses
Ergebnis stellt ein Korrektiv zur Hypothese des Chiemgau-Impakts dar, wonach
der Tüttensee ein Impaktkrater sein soll. Da diese nun falsifizierte
Annahme vor allem im deutschsprachigen Raum von zahlreichen Medien
propagiert wird, ist der folgende Artikel auf Deutsch verfasst, um einer
breiten Leserschaft zugänglich zu sein.
Physically based model for gully simulation: application to the Brazilian semiarid region

Abstract. Gullies lead to land degradation and desertification as well as increasing environmental and societal threats, especially in arid and semiarid regions. Despite this fact, there is a lack of related research initiatives. In an effort to better understand soil loss in these systems, we studied small permanent gullies, which are a recurrent problem in the Brazilian northeastern semiarid region. The increase in sediment connectivity and the reduction of soil moisture, among other deleterious consequences, endanger this desertification-prone region and reduce its capacity to support life and economic activities. Thus, we propose a model to simulate gully-erosion dynamics, which is derived from the existing physically based models of Foster and Lane (1983) and Sidorchuk (1999). The models were adapted so as to simulate long-term erosion. A threshold area shows the scale dependency of gully-erosion internal processes (bed scouring and wall erosion). To validate the model, we used three gullies that were over 6 decades old in an agricultural basin in the Brazilian state of Ceará. The geometry of the channels was assessed using an unmanned aerial vehicle and the structure from motion technique. Laboratory analyses were performed to obtain soil properties. Local and regional rainfall data were gauged to obtain sub-daily rainfall intensities. The threshold value (cross-section area of 2 m2) characterizes when erosion in the walls, due to loss of stability, becomes more significant than sediment detachment in the wet perimeter. The 30 min intensity can be used when no complete hydrographs from rainfall are available. Our model could satisfactorily simulate the gully-channel cross-section area growth over time, yielding a Nash–Sutcliffe efficiency of 0.85 and an R2 value of 0.94.
Siloxane treatment of metal oxide semiconductor gas sensors in temperature-cycled operation – sensitivity and selectivity

Published: August 2020

Abstract. The impact of a hexamethyldisiloxane (HMDSO) treatment on the response of doped SnO2 sensors is investigated for acetone, carbon monoxide and hydrogen. The sensor was operated in temperature cycles based on the DSR concept (differential surface reduction). According to this concept, the rate constants for the reduction and oxidation of the surface after fast temperature changes can be evaluated and used for quantification of reducing gases as well as quantification and compensation of sensor poisoning by siloxanes, which is shown in this work. Increasing HMDSO exposure reduces the rate constants and therefore the sensitivity of the
sensor more and more for all processes. On the other hand, while the rate
constants for acetone and carbon monoxide are reduced nearly to zero already
for short treatments, the hydrogen sensitivity remains fairly stable, which greatly increases the selectivity. During repeated HMDSO treatment the
quasistatic sensitivity, i.e. equilibrium sensitivity at one point during
the temperature cycle, rises at first for all gases but then drops rapidly for acetone and carbon monoxide, which can also be explained by reduced rate
constants for oxygen chemisorption on the sensor surface when considering
the generation of surface charge.

Aspects for the use of regional raw materials in ground food technology require further study of functional and technological properties to be able to predict them depending on the chemical composition of raw materials and processing methods. The aim of our research was to comparatively study the chemical composition, functional-technological, rheological properties of fish raw materials, and duck meat in terms of their possible compatibility in meat-containing products. The subject of our research was representatives of the regional aquaculture Carassius gibelio and Hypophthalmichthys molitrix, as well as the meat of Muscovy duck (Cairina moschata). It has been established that the nutritional value of freshwater aquaculture objects Carassius gibelio and Hypophthalmichthys molitrix  is virtually identical in protein and fat content, making them interchangeable in terms of nutritional balance when developing the combined product. The ratio of protein and fat to water for duck meat is higher 3.54 – 4.88 times that of aquaculture, which can be used in the selection of components of the formulation of emulsified products, taking into account the nutrient balance. It has been confirmed that the addition of salt enhances water holding capacity, water binding capacity, and fat holding capacity. Water holding and water-binding capacities of minced fish are higher due to higher water levels, which, combined with the low-watering duck meat, can be predicted to create a forcemeat system with high functional-technological properties. The ability to emulsification and retain fat in the state of emulsion in minced duck meat has proved to be better, which when combined with fish minced meat can compensate for the ability to retain fat in the system of combined products. A combination of regional aquaculture with waterfowl meat will not only improve the functional and technological parameters of combined minced systems but also balance them by correcting the composition of proteins and fats.

This research aimed to study the effect of modelled technological stress and the introduction of selenium and dihydroquercetin (DHQ) into pig diets on the microstructure of M. longissimus dorsi muscle tissue. The in vivo experiment was carried out on 36 hybrid young barrows (Large White x Landrace) x Duroc) with an initial live weight of 34 – 36 kg until they reached a weight of not less than 110 kg. The animals were divided into four groups: 1 (C-) – pigs did not receive adaptogens and were not subjected to modelled technological stress; 2 (C+) – pigs did not receive adaptogens but were subjected to stress via relocation of animals; 3 (С+Se) – pigs were subjected to stress and received 0.2 mg Se.kg-1 feed as selenium proteinate in addition to their diet; 4 (С+DHQ) – pigs were subjected to stress and received 32 mg DHQ.kg-1 feed in addition to their diet. The best results regarding the muscle tissue condition were recorded in the musle  L. dorsi samples were taken from the carcasses of group 4 (С+DHQ). Analysis of variance using the Fisher–Snedecor test confirmed that addition of adaptogens led to an improvement of the pH24 value (at p = 0.05, f observed  = 5.90 >fcritical = 4.17) and moisture-holding capacity (at p = 0.05, f observed  = 3.04 >fcritical = 2.92). The effect of long-term addition of DHQ to pig diets (78 days) on the condition of muscle tissue was studied for the first time, which allowed us to conclude its role in the prevention of myopathic changes in the muscle fibre structure.

Although Slovakia belongs to the smallest milk producers in the EU, we have to bear in mind the importance of the milk industry for the economy of Slovakia. Current expectations in Slovakia are that primary milk producers are able to produce milk at the lowest possible price, with state support on the same level as in other EU states, processing companies have a good purchasing price for the raw materials, retailers are able to share margins and to increase the market share of Slovak dairy products and last but not least that consumers buy milk and dairy products produced in Slovakia. Milk production in primary production has a profound ecological and social benefit for our countryside but the most important is the contribution of milk and dairy products to human health. The Slovak dairy sector has experienced three dairy crises and one butter crisis in the last ten years, what caused that up to 37% of milk producers in Slovakia cease their production. Currently, there are 401 approved primary milk producers in Slovakia. This sector is in long-term condition weakened by market fluctuation and by previous crises. Slovakia has a large investment debt in this sector. That is why in order of food security and maintaining employment it should be in the interest of the new government to do everything possible to stabilize this sector. Therefore, the primary objective of this scientific paper is to identify the needs of primary milk producers in Slovakia in relation to the strategic objective – to increase the competitiveness of the milk producers. The research aims to transform the voice of primary milk producers into the new programming documents for the upcoming period of the Common Agricultural Policy (CAP) for the years 2021 – 2027.
