O resultado das simulações indicou um payback médio de 11 anos, VPL de R$ 27,15 milhões e TIR de 16% ao ano. A partir das distribuições de probabilidade acumuladas pode-se inferir que o investimento em tela possui baixo risco e possui viabilidade financeira. Destaca-se a boa interação entre análise determinística e de risco, proporcionando informação de melhor qualidade para a tomada de decisão.
VALIDAÇÃO DE DOIS MODELOS NUMÉRICOS (AXISSIMÉTRICO E TRIDIMENSIONAL) PARA SOLUÇÃO DE PROBLEMAS DE MOLDAGEM LÍQUIDA
Authors: Oliveira Cristiano Peres , Reichwald Luis Guilherme Gierus , Amico Sandro Campos , Souza Jeferson Avila
Published: January 2020

No presente estudo, um modelo numérico é utilizado para reproduzir numericamente a Moldagem Líquida de resina no interior de um molde. Este molde foi projetado para medição da permeabilidade transversal de compósitos poliméricos. Como os ensaios experimentais são geralmente bastante onerosos, busca-se com a solução numérica uma forma de prever o comportamento da resina dentro do molde e desta forma diminuir o número de repetições experimentais. Visando minimizar as incertezas devidas a medições de variáveis adicionais (permeabilidade e porosidade), no presente trabalho, a metodologia para validação da solução numérica considerou apenas o molde em vazio, ou seja, sem o reforço fibroso. Destaca-se que do ponto de vista numérico, incluir o meio poroso depois do modelo validado não acarreta maior complexidade, visto que a região com o reforço fibroso é modelada como um termo de resistência ao fluxo que é adicionado na equação da conservação da quantidade do movimento. Esta resistência reduz a velocidade do escoamento e acaba facilitando a obtenção da solução. Foram realizados três ensaios experimentais sem reforço fibroso e médias da vazão volumétrica e da variação de pressão medidas foram calculadas. A partir dessa média foi estabelecido também um intervalo de confiança para que se pudesse realizar a comparação com os resultados numéricos. Finalmente, na comparação numérico x experimental, foi observada uma excelente concordância entre as soluções. Desta forma, considera-se que o modelo numérico foi validado e se encontra apto para resolver problemas de moldagem líquida.
Trade between Russia and the Maghreb: Trends and Prospects
Authors: Shkvarya Liudmila V.
Published: January 2020

The article analyzes the current state of trade and economic relations between Russia and the Maghreb. The author considers the objectives of this cooperation, its potential and dynamics, as well as models of its implementation. The author comes to the conclusion that the potential of trade and economic cooperation is far from exhausted. Trade relations between the two countries developed ambiguously in the formation of the tendency to increase trade turnover. Investments remain insignificant, however, in the presence of a number of joint projects. Trade is unbalanced, both by country and by export-import flows, by year. Among the reasons, the author highlights the lack of timely and reliable information about the state of the partner countries ' markets, their legislative framework, mentality and peculiarities of business culture, as well as the preservation of models of interaction that do not correspond to modern realities, including the lack of understanding of the importance of the region in Russia. The author substantiates the point of view that the parties have both the opportunity and the need to further develop the potential of trade and economic cooperation to strengthen the Russian presence in the region, represented by both public and private structures in a number of areas, among which a special place is occupied by energy, engineering, chemistry and petrochemistry. In addition, it is important to intensify the development of cooperation between the Russian Federation and the Maghreb countries in the social sphere, primarily in the areas of health and education, as well as in the cultural sphere.

Authors: Vasyukov Evgeny A.
Published: January 2020

In the context of a slowdown in global growth rates and under unfavorable foreign policy conditions, special attention should be paid to protective measures to stabilize the growth of the country's GDP. It was noted that not only the measures applied by the Central Bank, but also the level of communication with financial market participants have a significant impact on the formation of long-term expectations. It is shown that these factors significantly affect international capital flows and, as a result, the Russian economy. The conclusion is made about the need to stimulate domestic sources of economic growth in the context of international economic turbulence, the need to introduce a comprehensive package of measures using elements of both fiscal and monetary policies. The methodological basis of this study is the principles of a systematic comparative analysis of the interaction of market forces. The novelty consists in a comprehensive assessment of the state of sources of growth of the Russian economy in 2017-2018. in conditions of instability in the financial and economic sphere, and in identifying non-obvious factors that have a significant impact on economic growth rates. The main provisions, practical conclusions can be used to develop and implement monetary policy in the face of negative expectations from investors with the subsequent tightening of US monetary policy.
Structure-based Virtual Screening Approach for the Discovery of Potent Inhibitors of Aminoglycoside 6'-N-Acetyltransferase Type Ib [AAC(6')-Ib] against K. pneumoniae Infections
Authors: Uddin Reaz , Siraj Bushra , Rafi Sidra , Azam Syed Sikander , Wadood Abdul
Published: January 2020

Background:

Aminoglycoside 6'-N-acetyltransferase type Ib (AAC(6')-Ib) from Klebsiella pneumoniae is an established drug target and has conferred insensitivity to aminoglycosides. Aminoglycosides are often inactivated by aminoglycoside modifying enzymes encoded by genes present in the chromosome, plasmids, and other genetic elements. The AAC(6′)- Ib is an enzyme of clinical importance found in a wide variety of gram-negative pathogens. The AAC(6′)-Ib enzyme is of interest not only because of its ubiquity but also because of other characteristics e.g., it presents significant microheterogeneity at the N-termini and the aac(6′)-Ib gene is often present in integrons, transposons, plasmids, genomic islands, and other genetic structures. The majority of the reported potent inhibitors against the target are substrate analogs. Therefore, there is a need to develop or discover new scaffolds other than substrate analogs as AAC(6')-Ib inhibitor.

Objective:

The objective of this study is to set optimum parameters for the structure-based virtual screening by multiple docking and scoring methods. The multiple scoring of each ligand also incorporates the ‘Induced Fit’ docking effect that helps to build further confidence in the shortlisted compounds. The method eventually is able to predict the potential inhibitors that bind to the active site and can potentially inhibit the activity of the Aminoglycoside 6′-N-acetyltransferase type Ib [AAC(6’)-Ib] from Klebsiella pneumoniae.

Methods:

Using the available three-dimensional structure of enzyme AAC(6')-Ib inhibitor complex, a structure-based virtual screening was performed with the hope of prioritizing the promising leads. In order to set up the protocol, 30,000 drug-like molecules were selected from the ChemBridge library. Multiple docking programs, i.e. UCSF DOCK6 and AutoDock Vina have been applied in the current study so that a consensus is developed to the predicted binding modes and thus the docking accuracy. The Amber scores of the Dock6 – a secondary scoring function was also used to perform the ‘Induced Fit’ effect and correspondingly re-rank the compounds.

Results:

The top 30 ranked compounds of the most frequent scored were selected from the histogram. The 2D interactions of those 30 compounds were drawn from the Ligplot+ tool. Six of the compounds were prioritized as potential inhibitors as they are representing the maximum number of interactions from the rest of the compounds and also possess the drug-likeness as predicted by the estimated ADMET properties.

Conclusion:

This study provided useful insight that the proposed compounds have the potential to bind to the aminoglycoside binding site of AAC(6′)-Ib that may eventually inhibit the Klebsiella pneumoniae. This study has the potential to propose putative new and novel inhibitors against a resistant drug target of Klebsiella pneumoniae.
Simultaneous Determination of Lamotrigine, Topiramate, Oxcarbazepine, and 10,11-dihydro-10-hydroxycarbazepine in Human Blood Plasma by UHPLC-MS/MS
Authors: Zhao Qing , Jin Siyao , Liu Qingyang , Zhao Zhigang , Feng Weixing , Mei Shenghui
Published: January 2020

Background:

Lamotrigine (LTG), topiramate (TPM), and oxcarbazepine (OXC) are
commonly used antiepileptic drugs. The bioactivity and toxicity of these drugs were related to their
blood concentrations which varied greatly among individuals and required to be monitored for dose
adjustment. However, the commercial method for monitoring of these drugs is not available in China.

Methods:

A UHPLC-MS/MS method for simultaneous determination of LTG, TPM, OXC, and OXC
active metabolite (10,11-dihydro-10-hydroxycarbazepine, MHD) was developed and validated according
to the guidelines and applied in clinical practice.

Results:

he separation was achieved by using methanol and water (both contain 0.1% formic acid)
at 0.4 mL/min under gradient elution within 3 min. For all analytes, the isotope internal standard was
used; the selectivity was good without significant carry over; LTG and TPM were linear between
0.06 to 12 mg/L while OXC and MHD were linear between 0.03 to 6 mg/L, the upper limit could be
10-fold higher because 10-fold dilution with water did not affect the results; the intra-day and interday
bias and imprecision were -13.11% to 5.42% and < 13.32%; the internal standard normalized recovery
and matrix factor were 90.95% to 111.94% and 95.57% to 109.91%; and all analytes were
stable under tested conditions. LTG and OXC-D4 shared two ion pairs m/z 257.1 > 212.0 and 257.1 >
184.0, and m/z 257.1 > 240.0 was suggested for OXC-D4 quantitation. Lamotrigine and lamotrigine-
13C3 shared three ion pairs m/z 259.0 > 214.0, 259.0 > 168.0 and 259.0 > 159.0, and m/z 259.0 >
144.9 was suggested for LTG-13C3 quantitation. CBZ had a slight influence on OXC analysis only at
0.225 mg/L (bias, 20.24%) but did not affect MHD analysis. Optimization of chromatography conditions
was useful to avoid the influence of isobaric mass transitions on analysis. This method has been
successfully applied in 208 patients with epilepsy for dose adjustment.

Conclusions:

An accurate, robust, rapid, and simple method for simultaneous determination of LTG,
TPM, OXC, and MHD by UHPLC-MS/MS was developed, validated, and successfully applied in patients
with epilepsy for dose adjustment. The experiences during method development, validation,
and application might be helpful for other researchers.

Authors: Nagaraj G. , Senthil R.A. , Boddula Rajender , Ravichandaran K.
Published: January 2020

Objective:

Herein, we reported a simple and effective approach to synthesis of pure and
Ni2+ doped TiO2 nanorods by a photon-induced method (PIM) followed by calcination at 850 ºC in
air atmosphere.

Methods:

Basically, the PIM was used to tuning the properties of as-prepared TiO2 photocatalyst.
These obtained samples were further characterized by X-ray diffraction (XRD), scanning electron
microscopy (SEM), high resolution transmission electron microscopy (HR-TEM) and UV-visible
diffuse reflectance spectroscopy (UV-vis DRS) analysis. XRD results reveals that the both pure TiO2
and Ni doped TiO2 nanorods has anatase phase up to 850°C.

Results:

The HR-TEM analysis indicates that doping Ni is favourable to the formation of rod-like
TiO2 sample. Also, the observed photocatalytic results demonstrates that the Ni doped TiO2 can be
achieved a complete degradation of methylene blue (MB) within 30 min under direct sunlight irradiation
as compared to pure TiO2.

Conclusion:

Therefore, this work revealing the doped Ni has a good potential to modification of
TiO2 with an excellent photocatalytic activity for water treatment applications.
Production of Vincristine and Vinblastine by the Endophytic Fungus Botryosphaeria laricina Strain (CRS1) is Dependent on Stimulating Factors Present in Catharanthus roseus

Published: January 2020

Aims:

To isolate vinca alkaloid producing endophytic fungi from Catharanthus roseus and the evaluation of the factors which enhance the vincristine production.

Background:

An endophytic fungus Botryosphaeria laricina (CRS1) isolated from Catharanthus roseus demonstrated vinca alkaloid production under certain conditions.

Objective:

o Understand the conditions under which the fungus was able to produce vincristine and vinblastine.

Methods:

Fungal isolates from C. roseus were grown in liquid culture and screened for alkaloid production. The strain (CRS1) producing catharanthine was sequenced and matched with GenBank. This isolated strain was studied for production of vinca alkaloids and the conditions required for vincristine and vinblastine production.

Results:

Eight endophytic fungi were isolated from the fresh aerial parts of C. roseus. Only CRS1, demonstrated catharanthine production. DNA sequencing of CRS1 gave a 100% match with the GenBank accession number, KC509580.1, which is related to the Botryosphaeria laricina strain JAS6. CRS1 produced only catharanthine when cultured in Czapek’s peptone liquid medium (CZ). Addition of C. roseus fresh plant extract (8.0 mL) to the culture medium (4.0 L) stimulated the production of catharanthine (3.2 mg), catharanthinic acid (0.3 mg), N-demethyl-vinblastine (0.3 mg), vinblastine (2.8 mg) and vincristine (2.4 mg). However, if the added plant extract was preheated (80 ˚C, for 15 min), no vinca alkaloids appeared other than catharanthine. To identify the active fractions of the plant extract stimulating vinca alkaloid production, the extract was dialyzed in buffer at 4 ˚C through 20 kDa MW cutoff membrane to separate into two fractions of molecules above and below 20 kDa MW. Only the fraction containing molecules above 20 kDa was able to transform catharanthine to vincristine and vinblastine. When the dialysis was performed in water instead of buffer, the larger fraction could only produce catharanthine and vinblastine. Other conditions such as the presence of light:dark (12:12 h), fructose (30.0 g L-1), glucose (30.0 g L-1), Cu2+(0.1 mM) ions, L-tryptophan (0.1%) and succinic acid (1%) did not induce alkaloid production.

Conclusions:

The catharanthine producing fungal strain B. laricina (CRS1) could only produce the two vinca alkaloids, vinblastine and vincristine from catharanthine in the presence of active components larger than 20 kDa MW present in the plant extract of C. roseus.
Abscisic Acid, a Plant Hormone, Could be a Promising Candidate as an Anti-Japanese Encephalitis Virus (JEV) Agent
Authors: Bhimaneni Sai Priyanka , Kumar Anoop
Published: January 2020

Japanese encephalitis virus (JEV) is an arthropod-borne flavivirus that belongs to the Flaviviridae
family affecting millions of people worldwide. There is no specific drug approved for the
treatment of this infection and also available vaccines are not effective against all the clinical isolates.
Thus, the exploration of novel mechanistic pathways of existing molecules may help to develop more
effective anti-JEV agents. Abscisic acid is a naturally occurring phytohormone released particularly
in stress conditions, which controls leaf abscission. Recent studies have shown that the abscisic acid
has the potential to inhibit the virus by inhibiting protein disulfide isomerase enzyme, which is important
for the formation of viral proteins. Apart from this, abscisic acid could also reduce the neuroinflammation
(a major hallmark of JEV infection) through the stimulation of PPAR gamma. Thus,
abscisic acid thereof could have the potential to develop as an anti-JEV agent.
A Review of Catalytic Upgrading of Biodiesel Waste Glycerol to Valuable Products
Authors: Li Xue-Lian , Zhou Quan , Pan Shen-Xi , He Yu , Chang Fei
Published: January 2020

Glycerol is an organic polyol compound, and is an important raw material with extensive
applications in daily/petrochemical and pharmaceutical industry. Glycerol is typically obtained by
propylene chlorination, while the method used is complicated process and requires high energy consumption.
Interestingly, glycerol is recognized as a major by-product of biodiesel production. Approximately
100 kg of glycerol is yielded for 1 tonne of biodiesel production. With the rapid development
of the biodiesel industry, glycerol production capacity has been a serious surplus. This review introduces
the selective conversion of glycerol into a variety of value-added chemicals such as propylene
glycol, propanol, glyceraldehyde, and dihydroxyacetone via selective hydrogenation and oxidation, as
well as hydrocarbons and ethers via pyrolysis, gasification and etherification, respectively. The efficiency
of different types of catalysts and the influence of reaction parameters on the valorisation of
glycerol have been elucidated. Emphasis is also laid on the study of catalytic mechanisms and pathways
for some specific reactions.
Consumer Perceptions of Wearable Technology Devices: Retrospective Review and Analysis (Preprint)
Authors: Chong Kimberly P L , Guo Julia Z , Deng Xiaomeng , Woo Benjamin K P
Published: January 2020

BACKGROUND

Individuals of all ages are becoming more health conscious, and wearable technology devices (eg, Fitbit and Apple Watch) are becoming increasingly popular in encouraging healthy lifestyles.

OBJECTIVE

The aim of this paper was to explore how consumers use wearable devices.

METHODS

A retrospective review was done on the top-rated verified purchase reviews of the Fitbit One posted on Amazon.com between January 2014 and August 2018. Relevant themes were identified by qualitatively analyzing open-ended reviews.

RESULTS

On retrieval, there were 9369 reviews with 7706 positive reviews and 1663 critical reviews. The top 100 positive and top 100 critical comments were subsequently analyzed. Four major themes were identified: sleep hygiene (“charts when you actually fall asleep, when you wake up during the night, when you're restless--and gives you a cumulative time of “actual sleep” as well as weekly averages.”), motivation (“25 lbs lost after 8 months – best motivator ever!”), accountability (“platform to connect with people you know and set little competitions or group…fun accountability if you set a goal with a friend/family.”), and discretion (“able to be clipped to my bra without being seen.”). Alternatively, negative reviewers felt that the wearable device’s various tracking functions, specifically steps and sleep, were inaccurate.

CONCLUSIONS

Wearable technology devices are an affordable, user-friendly application that can support all individuals throughout their everyday lives and potentially be implemented into medical surveillance, noninvasive medical care, and mobile health and wellness monitoring. This study is the first to explore wearable technology device use among consumers, and further studies are needed to examine the limitless possibilities of wearable devices in health care.

Authors: Gupta Dhiraj , Potter Tom De , Disher Tim , Eaton Kiefer , Goldstein Laura , Patel Leena , Grima Daniel , Velleca Maria , Costa Graça
Published: January 2020

Atrial fibrillation (AF) ablation is most commonly performed using radiofrequency (RF) and cryoballoon (CB) catheters. Ablation Index is a novel lesion-quality marker associated with improved outcomes in RF ablation. Due to lack of direct comparative evidence between the latest generations of technologies, there is uncertainty regarding the best treatment option.
Aim:
To conduct a network meta-analysis to evaluate the comparative effectiveness of RF with Ablation Index to other catheter ablation devices in the treatment of AF.
Methods:
Searches for randomized and nonrandomized prospective comparative studies of ablation catheters were conducted in multiple databases. The outcome of interest was 12-month freedom from atrial arrhythmias after a single ablation procedure. Studies were grouped as high-, low- and unclear-quality based on study design and balanced baseline patient characteristics. Bayesian hierarchical network meta-analysis was conducted and results presented as relative risk ratios with 95% credible intervals (CrIs).
Results:
12 studies evaluating five different catheter ablation devices were included. Radiofrequency ablation with Ablation Index was associated with statistically significantly greater probability of 12-month freedom from atrial arrhythmias than Arctic Front (relative risk: 1.77; 95% CrI: 1.21–2.87), Arctic Front Advance™ (1.41; 1.06–2.47), THERMOCOOL™ (1.34; 1.17–1.48) and THERMOCOOL SMARTTOUCH™ (1.09; 1–1.3). Results were robust in multiple sensitivity analyses.
Conclusion:
Radiofrequency catheter with Ablation Index is superior to currently available options for 12-month freedom from atrial arrhythmias after AF ablation. This study provides decision-makers with robust, pooled, comparative evidence of the latest ablation technologies.

WHY PAY MORE - WORLD EVIDENCE ON M&A BID PREMIUM DETERMINANTS
Authors: Živanović Milutin , Džudović Nataša
Published: January 2020

Corporate mergers and acquisitions represent one of the most dynamic fields in the world of the business finance. These remarkably complex transactions success may vary depending on the economic and institutional environments in which the transactions are performed. This paper investigates the information content of the bid premium determined in the M&A transactions and focuses on the identification of significant differences in its amount depending on: (1) the observed timeframe (width of the event window observed relative to the moment of the transaction announcement); (2) current equity market trends (3) institutional environments and the degree of the economic development of the countries in which the transaction participants operate; and (4) selected payment method and motive for entering the transaction in regard to space and time dimensions of bid premium. Examining the sample of 783 merger and acquisition transactions at the global economy level, the research explores the importance and range of time and space determinants of bid premiums in M&A transactions.Our results confirm that bid premium carries significant information and that is highly dependent on the observed timeframe, i.e. we find evidence of information “leakage” prior to transaction announcement and sluggish adaptation to expected value creation due to market characteristics, level of economic development of countries in which M&As are operated and specific transaction characteristics such as payment method and motive for participating in such transaction. The paper shows that the results can often differ depending on whether the analysis includes dominant trends in the most important capital markets.

Islamic Feminist Exegesis by Amina Wadud
Authors: Mukhetdinov D. V.
Published: January 2020

The present article focuses on analyzing the methodology of one of the most prominent representatives of Islamic feminism, Amina Wadud. The author highlights the close link between the social status of an exegete, his/ her personal experience and the hermeneutic approach, formulated by him/ her. The essential components of the hermeneutic project by Anima Wadud are emphasized as a main theme of research. Combining intratextual and historical approaches is justified as being necessary for meaningful reconstruction of the “Qur’anic ethos”. It is also shown that feminist exegesis is only possible if the interpretation of the Qur’an as a “closed” text is replaced by the assertion of it being a complete discourse, “opening” within the logic of readers’ questions. The dependence of the exegeses by Amina Wadud on the conceptual body of the project by Fazlur Rahman — namely, on the idea of contextual ĳ tihad, the theory of “double shift” and the holistic method of interpretation, — was deeply studied during the research. The author accentuates the two primary presuppositions of the American feminist, namely: the image of God as “the One Who does not oppress” and of human being as God’s “deputy”. In conclusion, the author turns to the main theme of feminist critique of traditional tafsirs — the urge to deconstruct “patriarchy” as a covert system of idolatry and “masculinization” of God.
AVALIAÇÃO DO DESEMPENHO DE SISTEMAS DE TRATAMENTO DE EFLUENTE SANITÁRIO IMPLANTADOS NO MUNICÍPIO DE ESTRELA – RS
Authors: Brönstrup Martina
Published: January 2020

O descaso com o Saneamento Básico, gera impacto principalmente nos serviços de acesso à água potável, e à coleta e tratamento de efluentes sanitários. Um dos principais problemas em decorrência da crescente urbanização, é o lançamento de esgoto sem prévio tratamento, em particular em mananciais de abastecimento de água da cidade. O investimento neste âmbito ainda é insatisfatório, embora existam alternativas e tecnologias eficientes e com custos acessíveis para estas situações. O esgoto doméstico é constituído basicamente 99,9% de água e 0,1% de sólidos, e é por causa destes sólidos que se torna inevitável o tratamento do esgoto. Existem diferentes níveis de tratamento dos esgotos e são classificados em preliminar, primário, secundário e terciário. Entre os principais parâmetros que merecem destaque são os sólidos indicadores de matéria orgânica, Nitrogênio, Fósforo e os indicadores de contaminação fecal. No município de Estrela, foi avaliada a eficiência das estações de tratamento de efluentes através de análises de DBO5, DQO, sólidos suspensos totais, Fósforo, Nitrogênio e coliformes termotolerantes. Basicamente o método de tratamento de todos os sistemas existentes são anaeróbios. Os resultados não foram satisfatórios, pois não atenderam a todos os parâmetros exigidos pela Resolução 355/2017 do CONSEMA, principalmente na remoção de Nitrogênio, Fósforo e patogênicos. Como alternativa para aumentar a eficiência, é recomendado pós-tratamento de efluentes na remoção de nutrientes, como Nitrogênio e Fósforo, e também na remoção de agentes patogênicos.

The adequate storage of raw materials is fundamental to obtain a quality final product. The objective of this study was to evaluate the effect of different plastic packages on the maintenance of post-harvest quality of ‘Agata’ potato tubers stored under refrigeration and room temperature. Two experiments were conducted, both with a completely randomized design, arranged in a 3 x 4 factorial scheme (three types of packages – unpacked, with polyvinyl chloride film – PVC (21 cm x 40 cm and 12 μm thick) and with plastic bag (30 cm x 40 cm and 30 μm thick) and four evaluation times), with three replicates of one tuber each. In one experiment the samples were maintained under ambient conditions (25 ± 2°C and 60% ± 5% RH), with evaluations performed at 0, 7, 14 and 21 days, and another under refrigeration (8 ± 2ºC 75% ± 2% RH) and 0, 25, 50 and 75 days. The evaluated characteristics were: firmness, pH, soluble solids, total titratable acidity, vitamin C and the appearance of shoots. Tubers can only be stored under ambient conditions for seven days, and during this period the PVC packaging is the most suitable for storage. Tuber firmness was reduced and the vitamin C content of the last evaluation was higher than the initial content in both storage conditions. The refrigerated storage extended the shelf life of tubers for up to 50 days, period during which the PVC and plastic bags did not influence the conservation of the ‘Agata’ potato tubers.

Existence and uniqueness of solutions for the first-order non-linear differential equations with three-point boundary conditions
Authors: Mardanov Misir , Sharifov Yagub , Ismayilova Kamala
Published: January 2020

In this paper the existence and uniqueness of the solutions to boundary value
problems for the first order non-linear system of the ordinary differential
equations with three-point boundary conditions are investigated. For the
first time the Green function is constructed and the considered problem is
reduced to the equivalent integral equations that allow us to prove the
existence and uniqueness theorems in differ from existing works, applying the
Banach contraction mapping principle and Schaefer?s fixed point theorem. An
example is given to illustrate the obtained results.
Direct integration of systems of linear differential and difference equations
Authors: Kydyraliev Syrgak , Urdaletova Anarkul
Published: January 2020

Traditionally the Euler method is used for solving systems of linear
differential equations. The method is based on the use of eigenvalues of a
system?s coefficients matrix. Another method to solve those systems is the
D?Alembert integrable combination method. In this paper, we present a new
method for solving systems of linear differential and difference equations.
The main idea of the method is using the coefficients matrix eigenvalues to
find integrable combinations of system variables. This method is
particularly advantageous when nonhomogeneous systems are considered.
The structure of stands from different subassociations of a monodominant sessile oak forest (Quercetum petraeae Cer. et Jov. 1953.) in the area of northeastern Serbia before and after regeneration
Authors: Bobinac Martin , Andrasev Sinisa , Radakovic Nenad , Susic Nikola , Bauer-Zivkovic Andrijana
Published: January 2020

This paper presents the structure of well-preserved, mature stands of seed
origin and young stands that followed either after planned regeneration or
spontaneously in the understory reinitiation stage, in monodominant sessile
oak forests (Quercetum petraeae Cer. et Jov. 1953.) from two
subassociations, tilietosum and typicum, in the territory of ?Djerdap?
National Park. The presentation of mature stands is based on the data
collected from experimental plots in 1992, in the period characterized by
the mass occurrence of sessile oak decline in this area, and across Europe.
The stands were around 150 years old in 1992, and consisted only of sessile
oak in the tree layer. The canopy closure of the stands was 0.7-0.8, with a
large standing volume. There were no major differences between the stands
regarding social classes, stem quality, crown development and crown
condition. The presentation of young stands is based on the data collected
in 2017 from a permanent experimental plot, as well as on the data from
other authors. The structure of young stands indicates that different
silvicultural measures need to be planned during the regeneration stage for
different subassociations of the monodominant sessile oak forest in order to
reach sufficient natural regeneration of sessile oak.
Effect of site and provenance on the length of transfusion parenchyma of Douglas-fir needles

Published: January 2020

Douglas-fir has been the most common introduced conifer species in European
plantations since 1825. The analysis of the characteristics of the
introduced tree species by conducting genetic tests may predict the success
of transfer of Douglas-fir seed of different provenances. The projection of
the model of provenance test aims at providing information on adaptation to
habitat and climate conditions in new ecosystems in Serbia. The original seed
of Douglas-fir from North America was used for setting the experiment of
different provenances at two sites in Serbia. The first experiment was set
in a beech forest (Fagetum moesiacae montanum Jov. 1976) on district
cambisol in the area of Juhor mountain in central Serbia, while the second
one was set in Tanda near the town of Bor in eastern Serbia on the habitat
of Hungarian and Turkey oak (Quercetum frainetto-cerris Rud. 1949) on eutric
cambisol. Through the analysis of the anatomical structure of Douglas-fir
needles this paper tends to determine whether there are statistically
significant differences in the length of transfusion parenchyma of
provenances located in different habitats. The important function of
parenchyma in needles is the physiological process of water, organic and
mineral matter flow. The effects of the sites where the experiments were set
on the transfusion parenchyma of needles were determined by statistical
analysis.
From active audience to passive data: Dominant conceptualizations of internet users
Authors: Kleut Jelena
Published: January 2020

Within wider approaches to defining audience in communication studies, this
article aims to provide critical analysis of the terms which describe new
relations that appear between individuals and respective digital
communication centres. On the basis of the explicit and implicit
understanding of the agency of internet users, we identify several approaches
and terms characteristic of them. The first group includes concepts where
power is relatively equally distributed among the actors of digital
communication, with the terms such are user generated content and citizen
journalism at the forefront. Terms convergence culture and produsage belong
to the second group, and they see the networked individuals as empowered
challengers of the linear communication flows. The third group, defines users
as abstract sets of big social data without the individual agency. The fourth
group, with the terms such are small acts of engagement, locates user agency
in the practices of sense-making and everyday life. The key point of
divergence between these approaches is found in the answers they provide to
the following questions: who has the power, over what and how it is evaluated
in the totality of digital communication.
Political informing through social media across Europe - factors and effects
Authors: Petrovic Dalibor , Besic Milos
Published: January 2020

Social media play a significant role in political informing across Europe and
the rest of the world. That is why the political consequences of social
media use have become one of the prominent issues in contemporary social
research. In line with that, this paper investigates how the use of social
media for political informing is associated with the state of democracy in
European countries and how individual satisfaction with the level of
democracy and the political activism of citizens are affected by social
media use. We have used data from the latest European Value Survey,
conducted in 2017-2018. Our data sample included 30 countries with the
referent number of more than 56000 respondents involved in the survey. The
main finding of our research is that a deficit of democracy leads people to
use social media as a part of their political informing repertoires. This
finding applies to both, those who live in undemocratic circumstances and
those who live in developed democracies but have a negative personal
perception of democratic procedures in their country. It seems that once
citizens are ?forced? to use social media for political informing, they, in
turn, become influenced by media content displayed there and by other
peoples? ideas. In other words, the very use of social media makes them even
more critical of democracy and consequently more politically active, which
brings them back to social media.
Different approaches to the scientific investigation of music
Authors: Sreckovic Sanja
Published: January 2020

The paper deals with the approaches to researching music from the scientific
perspective. It is argued that the scientific literature concerning music
contains two different methodological approaches which significantly
determine the range of possible conclusions to be reached by the research.
The approach ?from the outside? investigates music by automatically applying
to music the more general conclusions concerning human cognition and other
capacities and behaviors. Thus, this approach omits music?s internal
factors. In contrast, the approach ?from within? consists in empirically
investigating reactions to music, capacities necessary for its
understanding, performing, etc., and their relationships with the reactions
and capacities outside the domain of music. The paper shows that, even
though the scientific research of music is still in the beginning stage, the
approach from within enables more complete explanations concerning music,
due to taking into account a larger number of factors relevant for
philosophical understanding of the phenomenon of music.
The Lateral Side
Authors: Goodfellow John , O'Connor John , Pandit Hemant , Dodd Christopher , Murray David
Published: January 2020

Lateral unicompartmental OA is a relatively rare disease said to account for about one eighth of all unicompartmental arthritis 1 . However, the incidence may be higher because it is a disease of flexion and is commonly missed on standing AP radiographs. To identify lateral OA reliably, either a valgus stress radiograph in 45° flexion or a Rosenberg view is necessary. The clinical results of UKA in the lateral compartment have sometimes been worse than in the medial compartment 2 and sometimes better 3 . Some early papers reported results of series containing both medial and lateral operations as if they were essentially the same, but the normal anatomy and the pathological lesions of the two compartments are very different so the surgical techniques are different.
Mobility and Stability of the Intact and Replaced Knee
Authors: Goodfellow John , O'Connor John , Pandit Hemant , Dodd Christopher , Murray David
Published: January 2020

Having demonstrated in Chapter 2 that a fully conforming mobile bearing can minimise polyethylene wear, in this chapter we show that a mobile bearing prosthesis, unconstrained in the sagittal plane, can restore natural mobility and stability. For surgeon readers who are less interested in the theoretical background, it might be advisable to go straight to Chapter 4, Indications, or to start by reading the final section of this chapter, The Loaded Prosthetic Knee. If that proves interesting, the surgeon might attempt The Unloaded Prosthetic Knee. For the more research minded surgeon or engineer, it seems more logical to start with the Unloaded Natural Knee (the longest section of the chapter) and to read from there. The chapter may also be of interest to those surgeons embarking on the use of a bi-cruciate retaining total knee replacement.

Authors: Karpinskaya T. A. , Kudryavtsev O. E.
Published: January 2020

Introduction. The paper is devoted to simulation modeling. Basic methods of the simulation mathematical modeling in the derivatives market are described. A group of realistic nonGaussian Levy processes that generalize the classical BlackScholes model is considered. The work objective is to study the most efficient methods of market forecasting, as well as the software implementation of the simulation mathematical modeling technique of the Russian derivatives market based on the Levy model. This research is relevant due to the demand for applications that simulate the dynamics of financial assets and evaluate options in realistic models of the derivatives market, allowing for jumps.

Materials and Methods. Basic methods for forecasting the derivatives market, methods for determining the volatility rate at a known option price, are considered. The most effective types of Levy processes for the simulation mathematical modeling of the Russian derivatives market at the present stage are highlighted. The possibilities of the Java language for the implementation of mathematical methods are considered.

Research Results. A program is developed in the Java programming language that implements the Levy mathematical model, which includes Gaussian and generalized Poisson processes. The program for calculating the mathematical method is created in the free integrated application development environment NetBeans IDE to work with any operating system.

Discussion and Conclusions. The result of the simulation mathematical modeling analysis has shown that the most efficient methods in the derivatives market are those based on realistic non-Gaussian Levy processes. The software implementation of such mathematical methods can be used for educational purposes. The developed application has demonstrated high quality and speed of calculations using software resources.
