Growth effect of income inequality in sub-Saharan Africa: exploring the transmission channels
Authors: Odusanya Ibrahim Abidemi , Akinlo Anthony Enisan
Published: May 2020

Sub-Saharan Africa (SSA) ranks as the second most unequal region globally (in terms of income distribution), harboring 10 of the 19 most unequal countries in the world. This paper explores the channels through which income inequality exerts its effects on economic growth in SSA. The study spans the period 1995–2015, focusing on 31 SSA countries. Findings from the two-step system generalized method of moments suggest that income inequality exerts a significant positive effect on economic growth via the saving transmission channel, while it has a statistically significant negative effect on economic growth in the region through the channels of fertility, credit market imperfection, and fiscal policy.
Mapping Green Infrastructure Elements Based on Available Data, A Case Study of the Czech Republic

Published: May 2020

The contribution of Green Infrastructure (GI) in vital areas such as regional development, climate change, agriculture, forestry and environmental protection is already acknowledged and listed as one of the priorities in several key EU policies, and is the basis for the EU Green Infrastructure Strategy. However, the concept is not yet fully integrated into actual planning strategies, in this respect the Czech Republic is no different. A major problem in doing so is a lack of guidelines/ how to identify and map GI using available sources and thus keeping costs down. The existing data sources for land cover or land use often do not fulfil the requirements in terms of thematic coverage, resolution or accuracy. In order to work around such limitations, we analyse the existing land use/land cover data in the Czech Republic from the GI perspective. Furthermore, we propose a GI mapping methodology based on the diagnosis of three mapping approaches at the regional level, grounded on the utilisation and processing of different data sets. We compared GI maps based on European data from CORINE Land Cover Database, Czech national database called Consolidated Layer of Ecosystems (CLE) and combination of Czech national and regional data and manual vectorization. Our results show that CORINE based GI map is suitable for transnational scale but unsuitable for regional scale. The CLE based GI map is good for both national and regional scale but its information on GI in urban areas is lacking. The detailed regional GI map is good for regional and to some degree even for local scale but its creation is time consuming. However, careful combination of existing national and regional data can provide good outcome in creating GI map usable for territorial planning.

The Loess Plateau is the main source of water in Yellow River, China. After 1980s, the Yellow river water presented a significant reduction, what caused the decrease of the Yellow river discharge had been debated in academic circles. We proceeded with runoff generation mechanisms to explain this phenomenon. We built saturation excess runoff and infiltration excess runoff generation mechanisms for rainfall–runoff simulation in Jingle sub-basin of Fen River basin on the Loess Plateau, to reveal the influence of land use change on flood processes and studied the changes of model parameters under different underlying conditions. The results showed that the runoff generation mechanism was mainly infiltration-excess overland flow, but the flood events of saturation-excess overland flow had an increasing trend because of land use cover change (the increase of forestland and grassland areas and the reduction of cultivated land). Some of the model parameters had physical significances，such as water storage capacity (WM), infiltration capacity (f), evapotranspiration (CKE), soil permeability coefficient (k) and index of storage capacity distribution curve (n) showed increasing trends, and index of infiltration capacity distribution curve (m) showed a decreasing trend. The above results proved the changes of runoff generation mechanism from the perspective of model parameters in Jingle sub-basin, which can provide a new perspective for understanding the discharge reduction in the Yellow River basin.

Published: May 2020

In agricultural land use, organic residues such as compost, digestate, and sewage sludge are discussed as costeffective soil conditioner that may improve the water holding capacity and crop available soil moisture. The objective of this study is to determine the effect of application of digestates with different compositions in maize, sugar beet and winter wheat, compost of shrub debris and sewage sludge on shrinkage behaviour and contact angle of till-derived loamy topsoil of a Haplic Luvisol under agricultural use. Novelty is the simultaneous determination of contact angle and shrinkage of soils amended with digestates composed of different composition in maize, sugar beet and winter wheat, compost of shrub debris and sewage sludge. The results suggest that the application of organic residues impacts the air capacity, while the contact angles remained in the subcritical range between > 0° and < 90°. The relationship between CA values and moisture ratios, ϑ, during proportional shrinkage was positive and linear (r2 of 0.98) and negative during residual- and zero-shrinkage (r2 of 0.93).

Published: May 2020

The role of stony soils in runoff response of mountain catchments is rarely studied. We have compared simulated response of stony soils with measured catchment runoff for events caused by rains of small and high intensities in the mountain catchment of the Jalovecký Creek, Slovakia. The soil water response was simulated for three sites with stoniness 10–65% using the Hydrus-2D single porosity model. Soil hydraulic parameters employed in the modelling, i. e. the saturated hydraulic conductivity and parameters of the soil water retention curves, were obtained by two approaches, namely by the Representative Elementary Volume approach (REVa) and by the inverse modelling with Hydrus-1D model (IMa). The soil water outflow hydrographs simulated by Hydrus-2D were compared to catchment runoff hydrographs by analysing their skewness and peak times. Measured catchment runoff hydrographs were similar to simulated soil water outflow hydrographs for about a half of rainfall events. Interestingly, most of them were caused by rainfalls with small intensity (below 2.5 mm/10 min). The REV approach to derive soil hydraulic parameters for soil water outflow modelling provided more realistic shapes of soil water outflow hydrographs and peak times than the IMa approach.
On Designing an Expert Diagnostic System of the Aircraft Turbine Engine Functional Units
Authors: Borowczyk Henryk , Spychała Jarosław
Published: May 2020

The paper presents issues related to the design of an expert diagnostic system of turbine engine functional units. Dedicated diagnostic stations and on-board flight data recorders are the sources of diagnostic signals. The signals were parameterized or identified dynamic models to get a compact representation in the form of a set of parameters. The set of diagnostic parameters was subjected to integer encoding. On this basis, a multi-valued diagnostic model describing the relationship between the set of faults and the set of symptoms (code values of diagnostic parameters) was determined. The proposed approach can be used in the design of expert diagnostic systems for propulsion units of any aircraft.

Published: May 2020

Introduction

The prohibition of antibiotic use in edible snails obligates breeders to treat bacterial infections by different means, of which a common one is a bath in Gram-positive– and partially Gram-negative–bactericidal ethacridine lactate solution. The aim of the study was to determine the effect of bathing Cornu aspersum Müller snails in a 0.1% aqueous solution of ethacridine lactate on selected physiological parameters of haemolymph.

Material and Methods

The study included 80 snails, divided into two equal groups (study and control). The study group was subjected to bathing in ethacridine lactate and the control group to bathing in tap water. Both groups were treated daily for seven days. The number of haemocytes in the haemolymph, the activity of alanine (ALT) and aspartate (AST) aminotransferases, and the concentration of urea were determined.

Results

In the study group, after exposure to ethacridine lactate solution an increase in ALT activity, changes in the De Ritis ratio, an increase in the amount of haemocytes, and a decrease in body weight were found. No such changes were detected in the control group snails or in animals after the first bath.

Conclusion

Multiple applications of a 0.1% ethacridine lactate bath may adversely affect Cornu aspersum Müller snails.

The aim of the article is to build an architecture of an information system similar to that used by modern enterprises, which will provide a combination of scientific, design and educational activities of the academic community, taking into account market needs. The main scientific research methods are bibliographic analysis, comparative analysis, methods of analogies. The conceptual architecture of the Information Support of Design Innovation Activity of the Technical University system based on the construction of a unified scientific and educational information space is described. The main task of the university’s information space is to prepare students for activities of the real market. There are determined the necessity and limits of application of the modern access control system at the universities of Ukraine, in particular for the organization of independent work of students. There is offered the way to reach the 4th level of technological readiness of students ‘and teachers’ development. The construction of an ontological description of the subject area of a technical university, the development of the application of a grid model for the description of scientific and technical information, and the determination of the current technical status are defined as the basis of the system of setting tasks for project groups in the transition to project-oriented learning. The question of the appropriateness of using adaptive case management system as a basic concept of building electronic document management system is resolved. The use of the competence approach as a mechanism of stimulating technical creativity within the educational process and in the work of researchers from the University staff is considered.
Averaging Attacks on Bounded Noise-based Disclosure Control Algorithms
Authors: Asghar Hassan Jameel , Kaafar Dali
Published: May 2020

We describe and evaluate an attack that reconstructs the histogram of any target attribute of a sensitive dataset which can only be queried through a specific class of real-world privacy-preserving algorithms which we call bounded perturbation algorithms. A defining property of such an algorithm is that it perturbs answers to the queries by adding zero-mean noise distributed within a bounded (possibly undisclosed) range. Other key properties of the algorithm include only allowing restricted queries (enforced via an online interface), suppressing answers to queries which are only satisfied by a small group of individuals (e.g., by returning a zero as an answer), and adding the same perturbation to two queries which are satisfied by the same set of individuals (to thwart differencing or averaging attacks). A real-world example of such an algorithm is the one deployed by the Australian Bureau of Statistics’ (ABS) online tool called TableBuilder, which allows users to create tables, graphs and maps of Australian census data [30]. We assume an attacker (say, a curious analyst) who is given oracle access to the algorithm via an interface. We describe two attacks on the algorithm. Both attacks are based on carefully constructing (different) queries that evaluate to the same answer. The first attack finds the hidden perturbation parameter r (if it is assumed not to be public knowledge). The second attack removes the noise to obtain the original answer of some (counting) query of choice. We also show how to use this attack to find the number of individuals in the dataset with a target attribute value a of any attribute A, and then for all attribute values a

i
∈ A. None of the attacks presented here depend on any background information. Our attacks are a practical illustration of the (informal) fundamental law of information recovery which states that “overly accurate estimates of too many statistics completely destroys privacy” [9, 15].
4. The Enescian Pianistic Notes and Commentaries (2st part)
Authors: Naie Lăcrămioara
Published: May 2020

George Enesco was a remarkable composer, conductor, teacher, violinist and pianist. He is one of the few “chosen” ones who lived under the emblem of the idea of BEAUTIFUL in its multiple images: by art, in the name of art and under the sign of art. Being in the circuit of authentic spiritual values, his entire pianistic creation is delicate, subtle, refined and elegant but extremely difficult as an artistic technique and expression; it calls for the intelligence accordingly, a lot of common sense, potential of much spiritual unrest, very much scenic experience, by determining the interpreters to very special refinement and expressive elevation, in addition to a worked touché trained in the art of the pianistic expression.
7. Echoes of Romanticism in Violin and Piano Sonata No. 2, Op. 45 by Marcel Mihalovici - Analytical Landmarks for an Upscale Interpretation
Authors: Florea Augustina
Published: May 2020

The evolution of the genre of violin and piano sonata in the Romanian composition creation in the first half of the 20th century, marked by the tendency towards getting close to the European musical phenomenon by assimilating stylistic influences of Romanticism, especially, of Enescian Romanticism, distinctly manifesting in Violin and Piano Sonata no. 2, op. 45, by Marcel Mihalovici, one of the most renowned Romanian composers settled in Paris, appreciated by the famous contemporaries, such as M.Ravel, V.d’Indy, F. Poulenc etc. Sonata (1941), preceded by a motto in the sonnet of Romantic poet Gérard de Nerval Myrtho: „Je sais pourquoi lá bas lé volcan s’est rouvert…”, impresses through the high emotional tension, metaphorically expressed by the image of the “woken” volcano, figurative suggestiveness of the musical language, architectonic innovativeness, spectacular capitalization of the violin technique in the formula of a violin-piano choir.
15. Stylistic-Interpretative Analysis of the Creation for Guitar Solo by Heitor Villa Lobos (Preludes no. 1-4)
Authors: Dragomirescu Daniel
Published: May 2020

Along with the structural analysis of the preludes, an interpretive analysis is extremely necessary for a practitioner of this instrument. Carlos Bonell, in an article in the specialized magazine “Guitar” (vol.11 of April 9, published in 1983), states that when the music of Villa-Lobos guitar parts becomes familiar to our ears, it is difficult let us imagine how they were in their “raw” state, in other words, how they were conceived in the composer’s imagination. But our duty as performers is to try to give this music its freshness and spontaneity, instead of imitating famous recordings or interpretations, which can only lead us to an outdated and at the same time lacking originality.
16. Trumpet and Orchestra Concert in D Major by Georg Philipp Telemann in Interpretation Vision of Wynton Marsalis and Rafael Méndez
Authors: Horez Iulian
Published: May 2020

Like most baroque concerts, the Concerto for trumpet and orchestra in D major by Georg Philipp Telemann raises particular problems of interpretation. It is a concert written in the head register of the trumpet, with frequent references in the acute register. I should mention that the head register of a trumpet depends on its size. At a normal trumpet in and flat (and not piccolo), the acute register is from do (and flat from the first octave) to the next do ascendant. The head register continues from do2 to do3. In the trumpets in do, re, mi flat, fa, sol, the principle remains the same, with a variability depending on the size of the trumpet, except that in the acute record the other notes correspond to that of the flat, but the upper limit is generally the same.

10. The Critical Role of Art Education in Community Building as Viewed by Art Teachers. A Qualitative Study
Authors: Pașca Eugenia Maria
Published: May 2020

The criteria recommended for the performance of internal assessment are the ones included in the national model for school inspection applied by the inspectors in the school inspectorate or the Ministry of Education (with subsequent names) who carry out internal assessments. Educational establishments can also decide on certain additional criteria - in line with the specific needs. All educational establishments must perform the annual assessment of activity, regarding school development, educational programs, curricular and extracurricular activities, quality of the teaching-learning process, human resources development, relations with the community and European dimension in the education offered. A tricky problem is represented by the specific assessment of Children Centres and Clubs that carry out non-formal activity, without school programs and handbooks approved by the Ministry of Education. Carrying out an analysis of the manner of assessing formal and non-formal educational units, the need to readjust the internal and external assessment was identified. At the level of school inspectorates, school inspection is carried out by a team consisting of specialised inspectors who know the specificity of those educational units. The main problem is represented by the external assessment carried out by ARACIP with the help of standard specific means: fields, indicators, reference descriptors and specific descriptors. Through the study performed, a series of proposals on the beneficial amendments for the quality assessment within Children Centres and Clubs is identified.

Published: May 2020

This article proposes a new technology of container carriage of rocks without construction of transport communications in an open-pit mine and with technological and energy-saving advantages. These advantages are: simultaneous excavation of rocks, transportation of rocks by the shortest distance, small mass of a container and mobility of a complex of hoists which will reduce energy expenses and the cost of transportation of the mined rock. One of the principal advantages of the developed technology is the decrease in environmental emissions into the atmosphere of the open-pit mine thanks to the reduction of the vehicle fleet. This technology will enable significant improvement of the environmental situation in the area of mining operations.

Authors: Ade Ibiwoye , Joseph Mojekwu , Francis Dansu
Published: May 2020

The survival rate of Small and Medium Scale Enterprises (SMEs) have been found to be low despite all the effort made by the government to sustain their existence. This seems to be linked to the poor management of various risk factors confronting the operators of the sector in Nigeria. In view of this, the study is aimed at determining the influence of Enterprise Risk Management (ERM) practices on survival of SMEs in Lagos State. With the application of cross-sectional survey technique, a sample of 400 operators was selected among SMEs across Lagos State. Data which were generated through structured questionnaires were analysed using both descriptive and inferential statistical tools. Results indicate that ERM practices significantly influence the survival of SMEs in Lagos State. Based on the findings, it was recommended that SMEs owners should take ERM practices as a valuable business function that enhances survival. Also, government should continue to sensitise SMEs on the benefits of ERM and put in place mandatory ERM guidelines to compel SMEs to practice it.
Does Better Management of Financial Obligation Promote Productivity?

Published: May 2020

The purpose of this paper is to examine the role of key financial obligation factors on total factor productivity (TFP) for 34 Indian industries for the period 2008 2018 using qualitative and quantitative techniques. Financial obligations are measured by short- and long-term loans, operating expenses and liabilities. The outcome of qualitative techniques does not appear to support the hypothesis that short term and long-term loans, liabilities and operating expenses influence TFP. On the contrary, the evidences arise from quantitative technique appear to suggest that short term loan and operating expenses promote TFP. The study also suggests that complimentaries exist between operating expenses and short-term loan and they together appear to boost productivity.

Published: May 2020

The purpose of this research paper is to explore the role of corporate governance of banks (independence of the board, board size, CEO duality, audit committee independence, managerial ownership) to boosting up the bank’s efficiency. The study uses bank size, macro-economic conditions, banking structure and economic freedom as control variables. The sample size of the study is 21 Pakistani banks for the period of 2007-2016 and fixed effect panel regression estimation technique is used for data analysis. The results suggest that corporate governance has a statistically significant negative impact on management efficiency, positive effect on profit efficiency and cost efficiency of the banks. Moreover, the findings show that operating efficiency turned out to have a statistically insignificant relationship with corporate governance. Reforms of corporate governance should be adopted efficiently and effectively to boost the banking sector efficiency.
The Analysis of Choreographic Concept in Merce Cunningham’s Creation
Authors: Todi Cristina
Published: May 2020

Through this I intend to bring again to the attention of practitioners of stage, musical, choreographic and theatrical arts, Merce Cunningham’s contribution to the development of modern choreography. The constant searches of yesterday, today and tomorrow’s artists is and will be a priority for those who want to bring something new and revolutionize art. Today, we distinguish distinctly the phenomenon of transgression of borders between the stage genres, especially between theater, music and choreography. Choreography migrates towards theater and music and theater and music strongly infiltrate into choreography. This emulation intends to create a total show but can still give birth to some artistic experiments where the accent is placed on the very visual interpretation with an excess of body movement and with an acute absence of Thalia’s simple and natural truths. Cunningham’s proposal on the way of assuming the body, the space and the rhythm is another challenge for today’s choreographers. The way of using these aspects and of acknowledging the strange infinity of its possibilities of transcending the communication barriers, reconfigures the body of the dancer as a linguistic entity with values still unexploited. Initiator of the choreographic modernism, Merce Cunningham is still nowadays an important reference for young choreographers.
Particularity and Proliferation of Stroboscopic Elements in the Visual, Performing and Cinematographic Arts
Authors: Caratănase Răzvan-Constantin , Dragoş Răzvan-Petrişor
Published: May 2020

In the work “Art and Visual Perception. A Psychology of the Author’s Creative Vision” by Rudolf Arnheim, following some researches/studies of Gestalt psychology applied in the field of visual arts and/or cinematography, the author states: “It is unlikely that any stroboscopic “short-circuit” will occur as long as objects appear on the screen at a sufficient distance from each other.” An observer-spectator only pays attention to what he/she receives. A speedy stream indicates unity. It is precisely for that reason that the vehement and effective ways are indispensable in order to render indisputably the intermittency-discontinuity. The stroboscopic dynamics overlooks the physical source of the visual tangible material. In that case, the visual identity does not start to be problematic as long as an element-object keeps staying in the same place without any inversion or transposition of its appearance - for example: the video camera that does not change its position but registers the building. For the same reason, we have the actor/actress who crosses the screen keeping his/her con-similarity (just walking down the path) without substantially changing his/her size or shape. The nature of the issues only appears under visual circumstances when they invoke/guide where it does not exist or vice versa. Alexander Archipenko (1887-1964): “In order to perform the movement, static painting must resort to symbols and conventions. It did not go beyond fixing a single “moment” in the sequence of moments that make up a movement; all other “moments” before and beyond the fixed movement are left to the imagination and fantasy of the spectator.”

Research has shown that using graphic novels in the classroom is one of useful approaches to promote the understanding of learners especially for lengthy and difficult literature texts. This study reports the extent of graphic novel in facilitating students’ understanding of literature and the students’ perceptions towards using graphic novel in learning literature (L2) as compared to other genre of texts. This is a mixed method study which employs quantitative and qualitative methods to obtain data. The findings indicate that most students found that graphic novel helped them to enrich their vocabularies and understand the text better. The findings also reveal that students were attracted to the illustrations in the literature text in which this helps to boost their motivation to learn literature in the classroom. The findings provide useful insights for English as Second Language (ESL) teachers in incorporating and expanding the literature learning through graphic novels in the future. The findings also imply the need of ESL teachers to use graphic novels effectively in facilitating their teaching and learning of literature in L2 classrooms particularly to suit the 21st century teaching and learning.

Dalam proses belajar mengajar, guru berperan penting dalam peningkatan mutu pendidikan. Untuk menghasilkan pendidikan yang efektif dan efisien, diperlukan metode mengajar yang sesuai. Penerapan suatu metode dalam pengajaran harus ditinjau dari segi keefektifan, keefesienan dan kecocokannya dengan karakteristik materi pelajaran serta keadaan peserta didik yang meliputi kemampuan, kecepatan belajar, minat, waktu yang dimiliki dan keadaan sosial ekonomi peserta didik. Selain itu, pembelajaran dengan metode mengajar yang sesuai dengan materi yang diajarkan dipercaya meningkatkan motivasi belajar peserta didik. Metode resitasi merupakan metode dimana guru memberikan tugas tertentu agar peserta didik melakukan kegiatan belajar. Dalam pembelajaran PAI (pendidikan agama islam), proses belajar peserta didik secara maksimal dapat di hasilkan melalui metode resitasi yang mana metode ini dapat dilaksanan baik di dalam maupun di luar kelas dan selama itu berada dalam lingkungan sekolah. Alasan penggunaan metode resitasi dalam pelajaran PAI adalah karena bahan pelajaran yang ada dirasakan terlalu banyak, sementara waktu yang tersedia hany sedikit. Artinya, banyaknya bahan yang tersedia dengan waktu kurang seimbang. Dengan demikian, agar bahan pelajaran selesai sesuai batas waktu yang di tentukan, maka metode resitasi inilah salah satu metode yang dapat digunakan oleh para guru PAI untuk.

Here, we successfully prepared macroscopically oriented films of Cu-based pillar-layered MOFs (Cu2(Linker)2DABCO) having regularly ordered 1D nanochannels. The direction of 1D nanochannels was controllable by optimizing the crystal growth process; 1D nanochannels either perpendicular or parallel to substrates, which offer molecular-scale pore arrays for a macroscopic alignment of functional guest molecules in the desired direction. We also showed the fabrication of oriented Cu2(Linker)2DABCO MOF patterns, where the direction of 1D nanochannels is controllable on individual locations on the same substrate. These Cu2(Linker)2DABCO MOF films and patterns with controlled orientation are importante steps towards the development of MOF film-based applications such as sensors and electrical/optical devices because functionalities derived from the accommodated guest species in their 1D nanochannels are optimized for the rational direction on the desired substrate for the device fabrication.

Ionic liquids (IL) are remarkable green solvents, which find applications in many areas of nano- and biotechnology including extraction and purification of value-added compounds or fine chemicals. These liquid salts possess versatile solvation properties that can be tuned by modifications in the cation or anion structure. So far, in contrast to the great success of theoretical and computational methodologies applied to other fields, only a few IL models have been able to bring insights towards the rational design of such solvents. In this work, we develop coarse-grained (CG) models for imidazolium-based ILs using a new version of the Martini force field. The model is able to reproduce the main structural properties of pure ILs, including spatial heterogeneity and global densities over a wide range of temperatures. More importantly, given the high intermolecular compatibility of the Martini force field, this new IL CG model opens the possibility of large-scale simulations of liquid-liquid extraction experiments. As examples, we show two applications, namely the extraction of aromatic molecules from a petroleum oil model and the extraction of omega-3 polyunsaturated fatty acids from a fish oil model. In semi-quantitative agreement with the experiments, we show how the extraction capacity and selectivity of the IL could be affected by the cation chain length or addition of co-solvents.

World Health Organization (WHO) reveals total number of coronavirus cases are 5,684,802 and 352,225 deaths till today worldwide. Coronavirus instances are nevertheless surging due to its speedy spreading through infected patients. Therefore, in order to find potent vaccine almost every researcher is doing hard work to find it. However, until today there is not any availability of effective vaccine or drug for the treatment of COVID-19. In this case, the computational approach is the good choice to identify effective drugs and could be very useful due to its low cost, less error and less time consumption. Here, Deketene curcumin has taken for docking study because of its lots of biological applications such as antiviral, antimicrobial, anti-inflammatory, antioxidant, antibiotic, and to a name of few, it is a derivative of curcumin. In this study, five main protease crystallized COVID-19 structures (PDB ID: 6LU7, 5R7Z, 5R7Y, 5R80, 5R81) have been taken for simulation against deketene curcumin. Required procedure for this in silico study done through Molegro virtual docker (MVD) and Molegro Molecular Viewer (MMV) used for visualization. The results showed H-bonding and steric interaction between Deketene Curcumin with COVID-19 (PDB ID: 6LU7, 5R7Z, 5R7Y, 5R80, 5R81). Moldock scores of Deketene Curcumin Observed -134.198 kcal/mol, -151.972 kcal/mol, -109.224 kcal/mol, -140.741 kcal/mol and -126.562 kcal/mol with PDB Id 6LU7, 5R7Z, 5R7Y, 5R80 and 5R81 respectively. As per our results, it can be say that Deketene Curcumin has effective as a lead compound to find new antiviral drug candidates against COVID-19 for possible medicinal agent.

Research on Bad Network Behaviours of Chinese College Students in the Media Age
Authors: Zhang Wei
Published: May 2020

Abstract: â€œEveryone is the mediaâ€ in this digital age and in the same way media have realized that information promulgation has produced enormous bad network conduct because of its autonomy, openness, concealment and unclear rights and responsibilities. In recent years such unhealthy phenomena, which are between legality and rationality become active in the grey area of network supervision and have brought new threats to the stability of the network order and eventual in making a bad impact on social orderliness. As the backbone of network users, college students have become the instruments of uncivilized behaviours in the network. The ideological and political education in colleges and universities is also facing unbelievable shocks and new challenges.
(Coverte) Modalität und Kontrollwechsel
Authors: Kotin Michail L.
Published: May 2020

Der Beitrag befasst sich mit kategorialen Relationen zwischen Subjekt-/Objektkontrolle und overten bzw. coverten Modalitätssignalen. Untersucht werden speziell komplexe Satzgebilde mit den Verba dicendi sagen und fragen in der Matrix und finiten bzw. infiniten (elidierten) Einbettungen, deren Prädikate auf das Subjekt oder aber auf das Objekt der Matrix referieren. Es wird gezeigt, dass der Wechsel von Subjekt- zu Objektkontrolle und umgekehrt direkt davon abhängig ist, ob modale Signale fehlen oder vorhanden sind. Die overte bouletische bzw. volitive (also kontrollierende) Modalität ändert die Kontrollverhältnisse nicht, während die overte deontische Modalität sie neutralisiert und kontextabhängig macht, und die coverte deontische Modalität sie genau umkehrt. Im letzten Fall geht der Kontrollwechsel mit Elidierungsoperation in der eingebetteten Proposition einher, die zu einer Infinitivergänzung wird. Die Schlüsselrolle spielt hierbei eine direkte Affinität der Anhebungssemantik der deontischen Modalität zur Diathese.
Aspekt und/oder Aktionsart – Chaos ohne Ende?
Authors: Schwenk Hans-Jörg
Published: May 2020

Der vorliegende Beitrag handelt von Aspektualität und Aktionalität im Deutschen und im Polnischen. Es konnte gezeigt werden, dass die lexikalische Opposition telisch vs. atelisch nicht mit der grammatischen Opposition perfektiv vs. imperfektiv verwechselt werden darf. Darüber hinaus liefert der Autor den Beweis dafür, dass innerhalb von Aktionalität ein scharfer Trennstrich zwischen Telizität als temporale Begrenztheit einer Handlung und dem Erreichen eines angestrebten Ziels, genannt Resultativität, zu ziehen ist.
