Variational quantum state preparation via quantum data buses
Authors: Kuzmin Viacheslav V. , Silvi Pietro
Published: July 2020

We propose a variational quantum algorithm to prepare ground states of 1D lattice quantum Hamiltonians specifically tailored for programmable quantum devices where interactions among qubits are mediated by Quantum Data Buses (QDB). For trapped ions with the axial Center-Of-Mass (COM) vibrational mode as single QDB, our scheme uses resonant sideband optical pulses as resource operations, which are potentially faster than off-resonant couplings and thus less prone to decoherence. The disentangling of the QDB from the qubits by the end of the state preparation comes as a byproduct of the variational optimization. We numerically simulate the ground state preparation for the Su-Schrieffer-Heeger model in ions and show that our strategy is scalable while being tolerant to finite temperatures of the COM mode.
Kashmir after August 5th Decision and its Implications for South Asia
Authors: Çelik Hatice
Published: July 2020

After World War II, Great Britain's loss of power in the international system had a great impact on the start of the decolonization process (the beginning of the independence movements in colonial geographies and the acquisition of peoples' independence) and expansion of it. India, one of the most important colonies of the British Empire which is known as the empire on which the sun never sets, was also the most important representative and perhaps even the trigger of this process. The Republic of India (hereafter referred to as India) which gained independence from Britain in 1947, also witnessed the birth of another state from its territory. The newly established state of the Islamic Republic of Pakistan (hereinafter referred to as Pakistan) has maintained a high-tension relationship with India since the foundation. The main cause of this tension has been the dispute over the Jammu and Kashmir region. The controversial region has again become a conflictual geography with the decision of the Indian Parliament on the 5th of August 2019. By this, the autonomous status of the J&K was abolished and Pakistan and India came to the edge of confrontation. The measures and precautions of the Indian government regarding the region has increased the tension not only in J&K but also in India and in Pakistan. This study tries to analyze the Kashmir dispute in line with the recent developments and how the issue effects the regional political dynamics. In the first part of the paper; there will be a short history of the dispute, the claims of the parties, and the place of this dispute in the international system. In the second part, the current situation will be tried to investigate from the foreign policy and regional policies aspect. The general conclusion of the author is that the recent decision on autonomy of Kashmir will have cumulative negative impacts on the stability of the region in coming years.
On Large-Time Behavior of Solutions of Parabolic Equations
Authors: Denisov Vasiliy N.
Published: July 2020

We study the stabilization of solutions of the Cauchy problem for second-order parabolic equations depending on the behavior of the lower-order coefficients of equations at the infinity and on the growth rate of initial functions. We also consider the stabilization of solution of the first boundary-value problem for a parabolic equation without lower-order coefficients depending on the domain Q where the initial function is defined for t =0.

In the first chapter, we study sufficient conditions for uniform in x on a compact K RN stabilization to zero of the solution of the Cauchy problem with divergent elliptic operator and coefficients independent of t and depending only on x. We consider classes of initial functions:

bounded in RN,

with power growth rate at the infinity in RN,

with exponential order at the infinity.

Using examples, we show that sufficient conditions are sharp and, moreover, do not allow the uniform in RN stabilization to zero of the solution of the Cauchy problem.

In the second chapter, we study the Cauchy problem with elliptic nondivergent operator and coefficients depending on x and t. In different classes of growing initial functions we obtain exact sufficient conditions for stabilization of solutions of the corresponding Cauchy problem uniformly in x on any compact K in RN. We consider examples proving the sharpness of these conditions.

In the third chapter, for the solution of the first boundary-value problem without lower-order terms, we obtain necessary and sufficient conditions of uniform in x on any compact in Q stabilization to zero in terms of the domain RN \ Q where Q is the definitional domain of the initial function for t =0. We establish the power estimate for the rate of stabilization of the solution of the boundary-value problem with bounded initial function in the case where RN \ Q is a cone for t =0.
What “the Semantic Sieve” Determines in the Process of Translation
Authors: Boasiako Albert Antwi
Published: July 2020

Semantics is meaning communicated through language (Saeed I.J.). Semantics is the study of relationship between words and their meanings; it is directly linked with the conceptual meaning of words, and the associative meaning. Semantic sieve as a concept is an innovative phenomenon. This linguistic phenomenon is a process whereby a word is dispersed through a semantic tunnel which in some cases produces different meaning. This is explained through different models. The semantic sieve is related to translation, where the deep structure of words differs from the surface structure. There are some concepts and words in Akan and English that are absent in Russian, others are known in Akan but virtually absent in the English language.
Language, culture and ideology in discursive practices
Authors: Bilá Magdaléna , Ivanova Svetlana V.
Published: July 2020

Discursive practices are looked upon as the core notion of discourse theory and the main instrument linguists can operate with studying language in connection with society and a human being. In this introductory article we will look into how language, culture and ideology are intertwined in diverse discursive practices and how these practices are shaped by people representing various cultures, ideologies and social entities. As part of linguistic discourse theory, we will briefly outline the major objectives and tenets of discourse theory or discourse analysis and track down the reasons why discourse theory turned into a dominant linguistic paradigm in the new millennium. Besides, some light will be thrown on the advancements and debatable questions arising within discourse theory as reflected in its methodology. Then we will give a brief synopsis of each individual paper and highlight theoretical and methodological contributions and innovations proposed by our authors. The results of the discussion as well as a brief outlook on future research will be summed up at the end of the introductory article.
Multimodal IT marketing discourse: An integrated approach investigation
Authors: Sokolova Natalia Vladimirovna
Published: July 2020

Websites of software vendors feature verbal and nonverbal means providing for a number of parameters to be taken into account in order to gain more comprehensive insights into the range and interplay of the means in use. This paper investigates the multimodal website marketing discourse of Microsoft , Oracle, and SAP relying on an approach which makes use of multimodal critical discourse analysis, pragmatics, and text linguistics. The integrated framework allows for consideration of the discourse-generating intention of the locutionary source, the discourse function, verbal content categories and audio-visual techniques employed in the nonverbal discourse contributing to the global category of ideologeme consisting of key ideas and aimed at the locutionary target. The intention of such discourse is to persuade consumers to purchase IT solutions which is manifested in the persuasive function. The textual content has been investigated in terms of a set of categories such as: the theme, including IT terms; tonality, made explicit through positively charged words and imperative sentences; time and space, emphasizing time saving efforts to deal with challenges enterprise-wide. The findings are similar to those revealed in the verbal content of customer testimonial videos, with audio-visual techniques such as invigorating music, company settings, contrast colors, etc. being alike. It is of particular interest that the linguistic means in these three marketing discourses are different only when it comes to metaphorical expressions. The global ideologeme is made explicit by urging customers to optimize data and feel IT-powered performance benefits. It is conveyed through multiple antitheses such as data challenges vs. one solution, previously vs. now, old vs. new, and slowly vs. fast. The antitheses in the three marketing discourses are similar as are the typical manifestations of categories and audio-visual techniques which may encourage further research in terms of making the specific discourse of a company stand out to its customers.
Discursive realization of threat in pre-election communication
Authors: Romanov Aleksey Arkad'evich , Novoselova Olga Vladimirovna
Published: July 2020

This article focuses on the question of pragmatic effectiveness of threat statements in political communication, in particular, the relevance of using threats in pre-election programs and intimidating voters with the goal of forcing them to vote for a certain politician. The aim of this article is to consider pre-election threat statements as verbal regulative actions and to propose a typology of such constructive menacives taking into account the targeted orientation of their consequent component. This study is based on a corpus of threat statements realized in the presidential candidates’ pre-election programs in Russia in 2018. The total number of menacives is 1. The study investigated the data from the perspective of the theory of speech activity, speech act theory and psychosemantics. The theoretical framework of the study is an action-related approach to the analysis of speech (dialogic) acts developed in Tver semantic and pragmatic research school (Romanov 1988; 2002; 2020). The study specified 18 targeted types of menacives that have a certain pragmatic and emotional effect on voters and are characterized by different frequencies in pre-election programs. This result demonstrates that the author of the pre-election program does not know mass voter’s preferences, their emotional state and feelings well; therefore, the politician directs their menacing influence on a wide range of potential voters. The authors conclude that politicians deliberately prefer to use threat statements with negative effect on an unfocused audience trying to win the attention and votes. The analysis shows that four types of threat statements with different targeting of consequent component proved to be a pragmatically effective tool in the Russian pre-election campaign in 2018. The results of this study can be used to predict the pragmatic effect of politicians’ threat statements on voters.

Identificación de acciones de salud en el Programa de Control de Sífilis en gestantes, Cartagena de Indias, 2016
Authors: Cárdenas Dávila Elvisa , Bedoya Marrugo Elías Alberto , Domínguez Yuri Arnold , Elin Manrique Julio
Published: July 2020

Fundamento. La Sífilis Congénita es una infección causada por la diseminación hematógena del Treponema pallidum de la gestante infectada al feto. Se conoce que la transmisión materna puede ocurrir en cualquier momento del embarazo, por lo que el control de la enfermedad en la gestante es vital en la atención prenatal. Objetivo. Identificar el cumplimiento de acciones de salud comprendidas en el Programa de Control de Sífilis en gestantes de la ciudad de Cartagena de Indias, primer semestre del 2016. Materiales y métodos: Estudio observacional descriptivo transversal. Se evaluaron 781 gestantes inscritas en control prenatal de la ciudad, a través de las instituciones prestadoras de servicios de salud (IPS) y empresas promotoras de salud (EPS). Resultados: Concluyeron la gestación 358 (45.8%) de las gestantes estudiadas. 25 (6.5%) del total, no se realizaron la VDRL intraparto. Durante el primer trimestre del embarazo, el 99.6% de las evaluadas resultaron VDRL no reactivas (NR). Mientras que en el segundo trimestre fueron evaluadas, el 67.5% y el 57,4%, respectivamente; resultando VDRL reactiva (R) una (0.1%) durante ambos semestres. Del segundo al tercer trimestre de la gestación no se incrementó el número de gestantes no evaluadas (98; 12,5%) y (63; 8, 1%), sin embargo, sí se incrementó (55; 19.8%) (269; 34.4%), respectivamente, el número de las gestantes que están a la espera del tiempo para realizar la prueba. No existió co-infección Sífilis/VIH/SIDA. Conclusiones. El control de la sífilis durante la atención prenatal fue deficiente dado por la alta tasa de no adherencia al cumplimiento de asistencia a la consulta por la gestante, como la no realización de la prueba acorde al tiempo establecido por parte del equipo de salud.

Chlamydia trachomatis (C. trachomatis) es una bacteria Gram negativa inmóvil, caracterizada por ser un microorganismo intracelular obligado y por poseer un ciclo reproductivo en el que puede distinguirse una forma infecciosa extracelular metabólicamente inerte (cuerpo elemental - EB’s), y una forma no infecciosa intracelular y activa (cuerpo reticulado - RB’s). C trachomatis se caracteriza por causar infección en humanos, está relacionada con enfermedades de transmisión sexual e infecciones oculares; por lo que puede conllevar a secuelas de interés, si no se da un tratamiento oportuno. El objetivo de este estudio fue optimizar el modelo de infección de C. trachomatis en células HEp-2 con cuerpos elementales (EB’s) de C. trachomatis serovar L2. Inicialmente, se establecieron las condiciones para el crecimiento adecuado de las células HEp-2 en tiempo y con una confluencia del 90%, para continuar con la optimización de un protocolo de infección. La infección fue confirmada a partir de la coloración con Giemsa permitiendo evaluar características morfológicas tanto de las células HEp-2 sin infectar e infectadas, y así mismo, de los cuerpos elementales de C. trachomatis. Finalmente, se corroboró la infección con la técnica de inmunofluorescencia directa que detecta la proteína de membrana MOMP de C. trachomatis. Tras los ensayos realizados se evidenció la presencia de cuerpos elementales próximos y dentro del citoplasma celular, así como células vacuoladas y daño celular causado por la infección.

Modeling of trihalomethane compounds formation in Baghdad water supply network
Authors: Ewaid Salam H. , Al-Farhani Bassam F. , Abed Salwan A. , Al-Ansari Nadhir
Published: July 2020

This study was conducted to measure the concentrations of four trihalomethane compounds (THMs) in raw, treated, and drinking water of seven water purification plants and the residential neighborhoods nearby in Baghdad. About 350 samples gathered between January and October 2017 and analyzed by the gas chromatography method. Results showed that THM annual levels in tap water ranged between 12 and 97.3 µg·l–1 in winter and summer consecutively, with a mean concentration of 60 µg·l–1, these concentrations did not exceed the level recommended by the WHO and the Iraqi standards. Statistical modeling by SPSS software for the formation of THM (the dependent factor) in the water supply network was undertaken using the measured water quality parameters (as independent factors) and utilizing multiple regression analysis. The model obtained has a high correlation (r = 0.842) and approved that the most affecting parameters on THM formation are total organic carbon, temperature, turbidity, total solids, and chlorine dose. The model that was derived may be used for the purposes of choosing appropriate THM-reduction procedures and the use of chlorine for improving the method of disinfection.

Published: July 2020

An investigation of the Mosul reservoir system within the Tigris river basin in Iraq was conducted to determine the ability of the system to generate hydroelectric power. A reproduction model utilizing the Simulink environment on the MATLAB platform was used to imitate the Mosul reservoir system. The reliability of the system under various future scenarios of data sources was also examined by employing a stochastic model used to create an inflow time series. The Thomas–Fiering model was chosen for this reason, which provided a wide range of data sources (inflows) to generate hydropower from the reservoir system under examination. Generally, the annual potential capacity of the Mosul basin for energy generation reaches 20,000 GW·h–1. Realizing that Iraq’s energy requirements are approximately 12 GW of power, and the integrating power production of the basin under examination is about 1.5 GW, this would cover around 12% of the total demand, which is significant.

Published: July 2020

The atmospheric parameters observations enable to made continental and global scales by remote sensing devices existent in space. One of these instruments is the Atmospheric InfraRed Sounder (AIRS) onboard Aqua satellite. We characterize the vertical distribution of troposphere carbon monoxide (CO) measured by AIRS over IRAQ. This study presents one year data. Results shown standard deviation of monthly troposphere CO for five locations: Baghdad, Basrah, Maysan, Al Fakka, and Mosul, from January to December 2012, was 107.15 ±18.75 ppbv for entire period depend on whether circumstance and topography. The seasonal differences undulate between winter and summer seasons, with higher values CO in the winter than in the summer and autumn seasons. In addition, the rising in troposphere CO values can be measured during year over the manufacturing and crowded urbanized zones. AIRS observations reveal enhanced abundances of CO, with values that can exceed 120 ppbv at approximately 4 km altitude over Baghdad and Mosul. The lower CO amounts observed of approximately 88–90 ppbv at 253 mb (altitude 11 km) during October. Comparisons over Baghdad station in 2012 showed close agreement between the ground CO data and the observed CO from AIRS, and regression result showed high correlation coefficient (R = 0.962). The vertical CO observation by AIRS is providing meaningful information for different altitude layers closer to the troposphere, and the satellite measurements are able to measure the increase of the atmosphere CO concentrations over varied regions.
Evaluation of yield and yield-related traits for waterlogging tolerance in mungbean genotypes using multivariate techniques
Authors: Shibly Nazmun , Islam Rafiqul , Hasan Mehfuz , Bari Nasimul , Ahmed Jalal
Published: July 2020

Waterlogging is a major constraint of mungbean production in the tropical and
subtropical regions of the world and can cause a significant yield loss. The
study evaluated 100 mungbean genotypes for tolerance to waterlogging
employing rigorous field screening procedures. Three-week-old seedlings of
100 mungbean genotypes were subjected to waterlogging for 3 days maintaining
a waterlogging depth of 2.5 cm. Waterlogging tolerance was evaluated during
the periods of recovery and final harvest considering relative performance
(values of waterlogging relative to non-waterlogging controls) of 18 plant
traits. All the genotypes showed a wide range of variation in relative
values. Some genotypes subjected to waterlogging produced plenty of
adventitious roots that contributed to foliage development and chlorophyll
increment, which resulted in better shoot growth, and eventually yield of
mungbean increased. Nine plant traits highly associated in waterlogged
conditions were used in cluster analysis. The genotypes within cluster 6 and
cluster 7 performed better regarding almost all plant traits whereas cluster
4 performed very poorly. Discriminant function analysis showed that function
1 and function 2 explained 54.5% and 32.2%, respectively and altogether
86.7% variation in the genotypes. The harvest index and straw dry matter
mostly explained the total variance in function 1. Dry matter of root, shoot
and straw explained the maximum variance in function 2. Root dry matter
played the most dominant role in explaining the maximum variance in the
genotypes. The genotypes IPSA-10 and VC 6379 (23-11) showed a better degree
of tolerance to waterlogging concerning yield and associated
morpho-physiological traits.
Effect of nitrogen levels and weed management methods on weed abundance and yield of upland rice (Oryza sativa L.)

Published: July 2020

Weed infestation and inherent low soil fertility are among the major factors
attributed to the low yield of rice in Nigeria. Field trials were therefore
conducted to evaluate the effect of nitrogen application levels and weed
control methods on growth and yield of upland rice (var. NERICA 2) at the
Teaching and Research Farm of the Federal University of Agriculture,
Abeokuta (07o 15?N, 03o 25?E) during 2015 and 2016 cropping seasons. Three
nitrogen (N) levels (0, 60 and 90 kg/ha) were evaluated and they constituted
the main plot treatments, while three weed control treatments, viz:
pre-emergence application of Orizo Plus? (propanil plus 2, 4-D) at 2.0 kg
a.i ha-1, Orizo Plus? at 2.0 kg a.i ha-1 followed by supplementary hoe
weeding (SHW) at 6 weeks after sowing (WAS) and three hoe-weeding regimes at
3, 6 and 9 WAS, and a weedy check constituted the sub-plot treatments. All
the treatments in different combinations were laid out in a randomized
complete block design with a split-plot arrangement with three replicates.
Results indicated a significant (p?0.05) increase in weed density and dry
matter with an increase in N application level from 0 to 90 kg ha-1.
Similarly, crop vigour and plant height increased significantly (p?0.05)
with increasing N application levels up to 90 kg ha-1. However, 60 and 90 kg
N ha-1 were at par in increasing the number of tillers, leaf area index and
yield attributes of rice. All the weed control methods resulted in a
significant (p?0.05) reduction in weed density and dry matter with
subsequent increase in rice growth and yield than the weedy check.
Pre-emergence application of Orizo Plus? followed by SHW at 6 WAS and three
hoe-weeding regimes resulted in significantly (p?0.05) lower weed density
and dry matter, and a higher number of tillers, panicle weight and grain
yield than a sole application of Orizo Plus?. With Orizo Plus? followed by
one SHW or three hoe-weeding regimes, increasing N application levels
resulted in a significant (p?0.05) increase in grain yield of rice. However,
with Orizo Plus? applied alone, increasing N application levels did not
increase rice grain yield. These results suggest that Orizo Plus? at 2.0 kg
a.iha-1 followed by one SHW at 6 WAS integrated with N application at 90 kg
ha-1 is adequate to effectively control weeds and increase rice yield in the
rainforest-savannah transition zone of Nigeria.
Bacterial inoculation: A tool for red clover growth promotion in polluted soil
Authors: Karlicic Vera , Radic Danka , Jovicic-Petrovic Jelena , Raicevic Vera
Published: July 2020

Red clover (Trifolium pratense L.) seeds were inoculated with several plant
growth-promoting bacteria (PGPB) and sown in the substrate contaminated with
polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs)
and organometallic derivatives of tin (OT). The aim was to determine if
selected PGPB strains can promote the growth of red clover in the substrate
contaminated with several organic pollutants. The influence of bacteria on
red clover growth (height, root length and biomass) was monitored during the
three-month experimental period. The most significant improvements of
seedling height were noted in the treatment with Bacillus amyloliquefaciens
D5 ARV and Pseudomonas putida P1 ARV. Root growth was positively affected by
Serratia liquefaciens Z-I ARV. The same isolates significantly affected
biomass production. Those isolates caused total biomass increases of 70%,
48% and 33% compared to control. Bacterial strains used in this study were
already confirmed as PGPB by biochemical testing, as well as by an in vivo
test of mixed inoculums on several woody plants grown in the coal-mine
overburden site. This work is the first-time record on their individual
effects on one plant species. Obtained results confirmed that inoculation
with several PGPB strains can enhance red clover growth in polluted soil.

China, known in the public as ?16 + 1? (i.e., ?17 + 1? starting in 2019).
Through an eclectic picture of the development of contemporary international
relations, the authors indicate in a methodologically accessible manner that
this mechanism of cooperation is a significant impetus for the development
of international relations. Since China has taken a dominant role in
redefining the Global Management System, whose goals are balanced and
sustainable international development, to achieve them, China has identified
certain ideological frameworks that are present in its foreign policy
through the Belt and Road Initiative. Through this Initiative, China seeks
to achieve the broader goals of the New Silk Road development strategy,
which not only determines the directions of China?s internal development,
but provides guidance for its strategic cooperation with neighbouring
countries as well as with countries on other continents. Consequently, the
mechanism itself thus plays an important role in strengthening China?s
foreign policy position, not only with respect to CEEC, but also with
respect to other European countries, including the EU as a whole.
China’s 21st century geopolitics and geo-economics: An evidence from the Western Balkans
Authors: Sekaric Nevena
Published: July 2020

This article advocates the thesis that the People?s Republic of China, in
accordance with a strong geopolitical strategy, is using geo-economics tools
in the context of reshaping global powers? influence in diverse parts of the
world. One of these spatial dimensions of Chinese emerging domination refers
to the Western Balkans, primarily through the economic presence of China in
this region. To address this issue first will be considered concepts of
geopolitics and geo-economics, followed by highlighting China?s presence in
the Western Balkans region and flourishing infrastructure projects in the
domain of transport and energy. The research is conducted by relying on the
existing databases on China?s economic involvement in different economy
sectors worldwide, mainly from China Global Investment Tracker (CGIT) and
AidData?s Global Chinese Official Finance Dataset for the WB countries in
the period 2013-2018. Special attention is given to China?s benefits in
terms of realizing those projects, even though the Western Balkans
countries? market is not attractive per se. Finally, some concluding remarks
have been made in terms of the potentials of China?s strategy to reconsider
political and security dynamics in the Western Balkans.
Twenty years after the NATO armed intervention: The Kosovo case and remedial secession
Authors: Hrnjaz Milos
Published: July 2020

The NATO military intervention in Yugoslavia took place twenty years ago,
triggering several important consequences not only regarding the Kosovo case
but also on the global level. This paper concentrates on the issue of the
relevance of the Kosovo Case for the concept of remedial secession. The main
argument of the paper is that the Kosovo Case is of the utmost importance
for the above concept because it has motivated numerous states to officially
accept the existence of remedial secession in international law. Several
decades ago, this was hardly imaginable. Even though the Kosovo Case has not
motivated states to change the formal sources of international law in this
regard, it could change the way international actors behave when they make
decisions about secession. Therefore, one of the conclusions of the paper is
that, after Kosovo, the genie of remedial secession could not be put back in
the bottle.
The European Union initiative for cooperation with neighbours in Eastern Europe and the South Caucasus: Objectives, limitations and challenges of integration without membership
Authors: Jovic-Lazic Ana
Published: July 2020

Following the enlargement of the Union, new neighbours in Eastern Europe and
the South Caucasus became of great importance for the stability of Europe,
which is why the EU formulated the European Neighbourhood Policy and the
Eastern Partnership. Bearing in mind that Russia views this area as a sphere
of its own influence, its policy has become of great importance as well as
its reactions to the Union?s initiatives in this region. This geopolitical
context of the Eastern Partnership became apparent with the outbreak of the
Ukrainian crisis. In addition to the indicated limits of an often
technocratic approach to the EU, the crisis has clearly shown there is a
conflict of objectives of the European Union and the Russian Federation in
the common neighbourhood and raised the issue of the security and
geopolitical implications of this initiative. Also, the policies and
interests of the European Union and the Russian Federation affect not only
Ukraine but to a greater or lesser extent the development of opportunities
in all other countries involved in the EU's Eastern Partnership - Georgia,
Moldova, Belarus, Armenia, and Azerbaijan.
How much we do (not) know about Russian-Serbian chanting connections
Authors: Peno Vesna
Published: July 2020

There are still no argumentative answers about the extent to which and in
what way the share of Russian singing practice in Serbian church singing is
present. The ways in which the Serbian melody reached Russian singers are
not known either. The paper presents the results of research on Russian
notated collections kept in Serbian libraries are also presented. Certain
stereotypes regarding the crucial Russian influence on the newer Serbian
church singing have been critically considered. New research tasks related
to Russian musical manuscripts are listed, after which the exchange of
singing experiences between Russian and Serbian church singers will become
clearer.
On the connection of musico-rhetorical strategies and Marian topic/topos in renaissance motets
Authors: Belic Senka
Published: July 2020

The text summarizes some of the research results from my doctoral
dissertation. In the broadest sense, the following text discusses the
influence of rhetorical concepts and practices on the composition practice
of the Renaissance. The methodological approach is interdisciplinary and
multilayered, and it leads to the interpretation of Marian motifs dating
from the late fifteenth to the end of the sixteenth century, in the context
of rhetorical ideas and principles, and the Marian topic / topos. The most
significant result of this text is the formation of a special analytical
method by which the interpretive-contextual reading of musical marking is
achieved.

Collisions of water drops in a gas-vapor environment at high temperatures and vapor concentrations
Authors: Shlegel Nikita , Strizhak Pavel
Published: July 2020

The study of the characteristics of secondary droplet atomization, leading to formation of an aerosol cloud of polydisperse child droplets appears to be promising. It is topical to assess the influence of properties of liquid and gas medium on the position of transition boundaries between the regimes of drop collisions and characteristics of the formed child droplets. This article presents the experimental results for the characteristics of drop collisions at various temperatures of the liquid and gas-vapor mixture and water vapor concentration in the latter with the aim of developing the prospective heat and mass transfer gas-vapor technologies. For this purpose, we have created the experimental set-up that allows varying the relative humidity of gas-vapor mixture in the area of drop collisions from 20-100%, its temperature from 20-100?C and the temperature of the liquid from 20-90?C. The test fluid is water. The collisions are recorded by a high speed video camera. The consequences of collision and the boundaries between them on the regime maps are determined in accordance using the approach, distinguishing: bounce, coalescence, separation, and disruption.
Determining of geometrical characteristic parameters of particle fractal aggregates from light scattering measurement signals
Authors: Xu Liang , He Zhen-Zong , Mao Jun-Kui , Han Xing-Si
Published: July 2020

Two kind of light scattering measurement methods, i.e. the forward light scattering measurement method and the angular light scattering measurement method, are applied to reconstruct the geometrical morphology of particle fractal aggregates. An improved attractive and repulsive particle swarm optimization algorithm is applied to reconstruct the geometrical structure of fractal aggregates. It has been confirmed to show better convergence properties than the original particle swarm optimization algorithm and the attractive and repulsive particle swarm optimization algorithm. Compared with the forward light scattering measurement method, the angular light scattering measurement method can obtain more accurate and robust results as the distribution of the fitness function value obtained by the angular light scattering measurement method is more satisfactory. Meanwhile, the retrieval accuracy can be improved by increasing the number of measurement angles or the interval between adjacent measurement angles even when the random noises are added. All the conclusions have important guiding significance for the further study of the geometry reconstruction experiment of fractal aggregates.

In this paper, based on the idea of reducing heat exchanger exergy destruction and increasing turbine work, a new three-stage cascade Rankine system and a new four-stage cascade Rankine system is proposed to improve the cold energy utilization rate during liquefied natural gas gasification on liquefied natural gas-floating storage and regasification unit. Then compare them with the original cascade Rankine cycle established under the same conditions. The results show that under the condition of 175 tonne per hour liquefied natural gas flow, the maximum net output power of the new three-stage cascade Rankine cycle system is 4593.31 kW, the exergy efficiency is 20.644%. The maximum net output power of the new four-stage cascade Rankine cycle system is 5013.93 kW, and the exergy efficiency is 22.509%. Compared with the original cascade Rankine cycle system, the maximum net output power of the new three-stage cascade Rankine cycle system and the new four-stage cascade Rankine cycle system is increased by 9.41% and 11.45%, respectively, and the system exergy efficiency is increased by 9.29% and 11.28%, respectively.
Optimization model for improvement of district heating system by integration of cogeneration
Authors: Gvozdenac-Urosevic Branka
Published: July 2020

Modelling of a complex district heating system by increasing the energy system efficiency and by reducing emissions through the implementation of new and low carbon technologies is presented. One of these technologies is cogeneration which is used to increase energy efficiency and to reduce CO2 emissions. Presented model uses linear programming as a basis for mathematical modelling of the energy system. The mathematical calculation is set pragmatically, so it can be efficiently and reliably used to assess the impact of most important parameters on the efficiency of the regional energy system. The model analyzes the effects of integration of cogeneration into the existing energy system using a given goal function. The basic criterion is set to be the reduction of environmental impact. The model is successfully tested on the complex district heating system with the power of about 600 MW.
The effect of steam on air gasification of mechanically activated coal in a flow reactor

Published: July 2020

A combined steam-gas plant with in-cycle steam gasification of coal and hot gas purification is considered as a promising technology for increasing the efficiency of energy production with simultaneous reduction in environmental impact. To intensify steam-air gasification, mechanical activation of fuel is used; it consists in high-stress grinding in a mill-disintegrator. The supply of steam to the gasifier allows an increase in reactivity of fuel, suppression of sorbent decomposition in the unit of hot desulfurization, reduction in the steam load on the shift reactor, increase in useful external work of gas turbine expansion, reduction in nitrogen oxide formation, and general increase in the efficiency and ecological compatibility of energy generation. On the other hand, a significant amount of steam can deteriorate the heat balance and efficiency of the gasifier. In this work, the influence of the steam/fuel ratio on steam-air gasification of mechanically activated Kuznetsk coal in a flow reactor was studied experimentally. The excess air coefficient was maintained constant and equal to 0.51, which corresponded to a temperature at the reactor outlet of about 1100?C. When steam was supplied, the fuel and air-flow rates were adjusted to ensure a constant gas-dynamic regime. To evaluate the obtained regimes, the heat and material balances were compiled. A positive effect of steam on characteristics of the gasification process was revealed. For the studied coal, the maximum degree of coal conversion and the calorific value of synthesis gas are achieved with a steam/fuel ratio of about 0.4 kg/kg.

We performed general anesthesia for a lip repair and palatoplasty in a patient with left ventricular hypoplasia following a Glenn procedure. Preoperative examination revealed hemorrhagic diathesis, hypoxemia, and secondary polycythemia. After completion of the palatoplasty, hypoxemia and intraoral bleeding were observed, and reintubation was required. The bleeding risk was likely increased in this patient due to several factors including the surgical procedure and concurrent antithrombotic therapy. In conclusion, the risks associated with hypoxemia and increased bleeding must be considered for the safe provision of general anesthesia during palatoplasty procedures in patients with cyanotic heart disease.
