Low-Frequency Fluctuations In The Flow Over Confined Cylinder In A Narrow Rectangular Duct At Re = 3 750
Authors: Palkin Egor , Mullyadzhanov Rustam
Published: December 2021

Flows between two closely spaced bounding surfaces are frequently appear in engineering applications and natural flows. In current paper the flow over a cylinder in a narrow rectangular duct was investigated by numerical computations of Navier-Stokes equations using Large eddy simulations (LES) at ReD = 3 750 based on cylinder diameter and the bulk velocity at inflow boundary. The influence of the bounding walls was demonstrated by comparing mean flow streamlines with the flow over an infinite cylinder at close Reynolds numbers. A comparison between the time-averaged velocity field in front and past the cylinder with experimental from the literature data showed good agreement although the characteristic horseshoe vortex structures are highly sensitive to Reynolds number and turbulence level at inflow boundary. Most energetic modes in recirculating region were revealed by spectral analysis. These low-frequency modulations were characterized by the pair of dominating vortices which are expected to have high influence on the heat transfer in near wake of the cylinder.

Published: December 2021

The experimental investigation of the influence of the distributed blowing of heavy gas (sulfur hexafluoride of SF6) into the wall layer of supersonic flat-plate boundary layer (at free-stream Mach number M = 2) on the laminar-turbulent transition have been performed. For the first time experimentally it is shown that in case of such blowing there is a boundary-layer stabilization, and the laminar-turbulent transition is removed from the model leading edge.

Seismic design of acceleration-sensitive non-structural elements in New Zealand: State-of-practice and recommended changes
Authors: Rashid Muhammad , Dhakal Rajesh , Sullivan Timothy
Published: December 2021

Acceleration-sensitive non-structural elements not only constitute a significant portion of a building’s component inventory, but also comprise components and systems that are indispensable to the operational continuity of essential facilities. In New Zealand, Section 08 of the seismic loadings standard, NZS 1170.5: Earthquake Actions, and a dedicated standard, NZS 4219: Seismic Performance of Engineering Systems in Buildings, address the seismic design of non-structural elements. This paper scrutinizes the design provisions for acceleration-sensitive non-structural elements in NZS 1170.5 and NZS 4219, and provides an international perspective by comparing with the design provisions for non-structural elements specified in ASCE 7-16, the latest ATC approach and Eurocode 8. This is followed by a detailed discussion on the improvements required for component demand estimation, the need for design criteria that are consistent with performance objectives, definition of realistic ductility factors, and recommendations for the future way forward in the form of an improved design procedure and its application through a new seismic rating framework.
The Water Requirements of Grapevines (Vitis vinifera L.) Under Climatic Conditions of Central Poland
Authors: Rolbiecki Stanisław
Published: December 2021

The purpose of this study was to estimate the water needs of grapevines in central Poland in 1981-2010. Water needs were calculated by the plant coefficients, which were assumed according to the Doorenbos and Pruitt method. Reference evapotranspiration was assessed by the Blaney-Criddle’s equation, modified for Polish conditions. Rainfall deficit with the occurrence probability of normal, medium dry and very dry years was determined by the Ostromęcki’s method. Water needs of grapevines during the growing season was 434 mm. Upward time trend in the water needs both in the periods May-October and June-August was estimated. Temporal variability in the water needs was significant for most of the provinces. The rainfall deficit was recorded with the occurrence probability of normal as well as medium or very dry years in the entire study area. Due to climate changes, vineyards will require irrigation in the near future. This research significantly broadens and refines the knowledge about the water needs of grapevines in central Poland, which will allow the design of resource-efficient irrigation programs for grapevines in the studied region of Poland.

Published: December 2021

Electricity demand is increasing with the development of technology in various fields, such as agriculture, medicine, automotive and others. But for controlling electricity in a room or building there are still found to be less efficient.

In controlling electricity or remote control using SMS need to pay attention to the signal that is on the SIM800L sms module. The way to get a signal is the need for power supply above 2 amperes for this SIM800L module.

This final project produces a tool that can control electricity in a room that is connecting and disconnecting the electricity supply using an RFID card which can turn on and off each room, even more than two outputs at once, and use SMS media for remote control.

Authors: Wang Jianwei
Published: December 2021

Lexical approach has been believed to be an ideal way for language teaching and learning, but few empirical studies are concerned with the effects that lexical approach has on art major students’ English writing. This study aims to explore the effects the lexical has on writing through an experiment in which the lexical approach was applied in an English class for art majors. All of them attended the pre-test before the experiment and the post-test after the experiment. Through analyzing the data of composition scores and the number of lexical chunks used in compositions by paired sample t tests, this study finds that the lexical approach has positive effect on art majors’ writing proficiency and it is quite feasible and effective to apply the lexical approach to college English teaching, especially in English writing teaching. 

 
Preservation of Features of Anatomical Polymorphism of Deschampsia antarctica É. Desv. (Poaceae) During In Vitro Clonal Reproduction
Authors: Nuzhyna Nataliia , Kunakh Viktor , Poronnik Oksana , Parnikoza Ivan
Published: December 2021

We studied the anatomical features of the leaf structure of
Deschampsia antarctica
É. Desv. (Poaceae) obtained from seeds collected from different habitats of the maritime Antarctic. These plants have been maintained in culture in vitro for more than 7 years. The plants include stable chromosome forms comprising diploids (2
n
= 26), a diploid plant with B-chromosomes (2
n
= 26 + 0–3B), a triploid with rearranged chromosome morphology, and myxoploids with different ratios of diploid and nondiploid cells in the root meristem. The
D. antarctica
plants that were studied generally had a similar anatomical structure in culture in vitro and in nature. At the same time, plants of different cultivated genotypes also displayed their own leaf structure features. In particular, qualitative features included asymmetric four-ribs and five-rib leaves instead of typical three-rib leaves for some genotypes, some individuals characterized by the presence of unicellular nonglandular pointed trichomes on an adaxial side, differences in vascular bundle sheath, and other features. No clear dependence of the anatomical structural features on the chromosomal status of the studied genotypes was evident. At the same time, differences were evident in traits that included the number of stomata, thickness of the outer cell walls of the epidermis, bundles sheath state, number of leaf ribs, and the persistent presence of trichomes under prolonged in vitro cloning. The findings indicate that
D. antarctica
plants collected from different locations of the maritime Antarctic for long-term cultivation in vitro under standard cultivation conditions retain the anatomical characteristics of the wild plants. The polymorphism of in vitro-cultivated plants is not related to the polymorphism of their karyotype, but is apparently due to the heterogeneity of the original plants and possibly the epigenetic fixation of a number of anatomical features produced in the natural microhabitats of
D. antarctica
populations.
Free vibration analysis of imperfect functionally graded sandwich plates: analytical and experimental investigation
Authors: Njim E.K. , Bakhy S.H. , Al-Waily M.
Published: December 2021

Purpose: This paper develops a new analytical solution to conduct the free vibration analysis of porous functionally graded (FG) sandwich plates based on classical plate theory (CPT). The sandwich plate made of the FGM core consists of one porous metal that had not previously been taken into account in vibration analysis and two homogenous skins. Design/methodology/approach: The analytical formulations were generated based on the classical plate theory (CPT). According to the power law, the material properties of FG plates are expected to vary along the thickness direction of the constituents. Findings: The results show that the porosity parameter and the power gradient parameter significantly influence vibration characteristics. It is found that there is an acceptable error between the analytical and numerical solutions with a maximum discrepancy of 0.576 % at a slenderness ratio (a/h =100), while the maximum error percentage between the analytical and experimental results was found not exceeding 15%. Research limitations/implications: The accuracy of analytical solutions is verified by the adaptive finite elements method (FEM) with commercial ANSYS 2020 R2 software. Practical implications: Free vibration experiments on 3D-printed FGM plates bonded with two thin solid face sheets at the top and bottom surfaces were conducted. Originality/value: The novel sandwich plate consists of one porous polymer core and two homogenous skins which can be widely applied in various fields of aircraft structures, biomedical engineering, and defense technology. This paper presents an analytical and experimental study to investigate the free vibration problem of a functionally graded simply supported rectangular sandwich plate with porosities. The objective of the current work is to examine the effects of some key parameters, such as porous ratio, power-law index, and slenderness ratio, on the natural frequencies and damping characteristics.
Automatizuotas arbitraliųjų kolokacijų atpažinimas: būdvardžių ir daiktavardžių kolokacijos
Authors: Kovalevskaitė Jolanta , Rimkutė Erika , Vaičenonienė Jurgita
Published: November 2021

Straipsnyje analizuojamas vienas kolokacijų tipas – arbitraliosios kolokacijos. Jos laikomos nemotyvuotomis (tuo skiriasi nuo kito kolokacijų tipo – trivialiųjų, arba motyvuotųjų, kolokacijų, pvz.: graži diena, naujas tyrimas), joms būdingas ribotas leksinis junglumas: pagal panašią reikšmę teoriškai galima rinktis daugiau negu vieną žodį, bet linkstama vartoti būtent kurį nors vieną, pvz., platus akiratis, bet ne didelis akiratis, stipri sveikata, bet ne galinga sveikata.
Analizuotos iš „Lietuvių kalbos pastoviųjų žodžių junginių duomenų bazės“ atrinktos visos kolokacijos, sudarytos iš būdvardžių ir daiktavardžių (apie 5000 junginių). Nustatyta, kad iš jų apie 650 yra arbitraliosios kolokacijos. Atrenkant šias kolokacijas, taikytas sinonimų pakeičiamumo testas: jeigu kolokacijos būdvardiškasis dėmuo (būdvardis ir būdvardiškai vartojamas dalyvis) nėra pakeičiamas kitu artimos reikšmės sinonimu, tokia kolokacija laikoma arbitraliąja. Šis arbitraliųjų kolokacijų atrankos procesas buvo automatizuotas: automatiškai atrenkant artimus būdvardžių sinonimus junginiuose su daiktavardžiais, pritaikytas žodžių vektorių modelis. Automatiškai būdvardžiai ir dalyviai sugrupuoti į maždaug 800 vektorių eilučių. Straipsnyje aprašyta, kaip vyko duomenų analizė, vertinimas ir tikslinimas, kokios kolokacijos ir kiek jų pripažintos arbitraliosiomis naudojant šį metodą.

Authors: Trzmiel Tomasz , Pieczyńska Anna , Zasadzka Ewa , Pawlaczyk Mariola
Published: December 2021

Objectives 
The aim of this cross-sectional study was to assess the effects of past occupational activity on muscle strength and respiratory function among retirees. 
Methods 
A total of 205 community-dwelling older adults participated in the study. Age (≥60 years) and cessation of professional activity (retirement) constituted the inclusion criteria. The International Standardized Classification of Occupations (ISCO-08) was used to stratify the participants into white-or blue-collar groups. Forced vital capacity (FVC), forced expiratory volume (FEV) in the first second, inspiratory vital capacity (IVC) parameters, and hand grip strength were tested. 
Results 
Statistically significant differences in IVC and FVC scores were found in white- and blue-collar workers after adjusting for sex and age (ANCOVA). White-collar men had significantly higher IVC as compared to blue-collar men. 
Conclusions 
Blue-collar male workers may be prone to deteriorating respiratory function in older age. It is vital to promote physical activity and educate blue-collar workers about the need to use respiratory protective equipment.
The Truth As We Know It
Authors: Dueben Rebecca ,   After Dinner Conversation
Published: December 2021

How should adults help children who are being bullied? How is childhood trauma adapted into adult relationships? In this work of philosophical short story fiction, Celia has been married six years to Jason, an ex-military man 20 years her senior. Celia’s child, Theo, is the result of Celia’s abusive father raping her as a teen. Theo is a short, overweight, awkward child who is teased at school. Jason continues to try to tease him and create experiences to “make a man out of him.” One day, when Jason and Theo go fishing, Theo is laughed at once too often and pushes Jason off the bridge, to his death. Now Celia is left to decide if she tells the truth about what happened, or tries to frame the death as a slip and fall accident.
LIBERDADE DE EXPRESSÃO E SEUS LIMITES: CONTRIBUTO PARA O ESTUDO DO TEMA A PARTIR DE JEREMY WALDRON
Authors: Leão Martha Toribio
Published: December 2021

O objetivo deste artigo é analisar criticamente a teoria de Jeremy Waldron sobre a liberdade de expressão e a regulação do discurso de ódio. Para tanto, o artigo está dividido em três partes. Na primeira parte, analisa-se a teoria de Jeremy Waldron sobre liberdade de expressão a partir do exame dos seus três pilares (dignidade, sense of assurance e vulnerabilidade), e demonstra-se que a teoria de Waldron permite o sopesamento dos princípios especialmente em virtude das consequências produzidas pelo discurso. Na segunda parte, são apresentadas as principais críticas formuladas por Edwin C. Baker e Ronald Dworkin à teoria de Jeremy Waldron, bem como as respectivas respostas. Na terceira parte, defende-se a crítica formulada por Ronald Dworkin à teoria de liberdade de expressão de Jeremy Waldron, no sentido de que essa permite a restrição da liberdade de expressão ainda quando isso represente uma violação a um direito individual. O artigo conclui que a tese de Waldron falha em criar critérios objetivamente controláveis para definir as hipóteses nas quais o discurso de ódio deve ser proibido ou regulado.

Neste contexto de intenso e constante desenvolvimento, cabe à Autoridade Nacional de Proteção de Dados regular e complementar a Lei Geral de Proteção de Dados, além de fiscalizar o seu correto cumprimento. Neste artigo, objetiva-se evidenciar algumas ferramentas para o enforcement da LGPD no cenário do capitalismo de vigilância, tais como os “Códigos de Boas Práticas” e a regulação e fiscalização por parte da ANPD. Empregou-se nessa pesquisa, o método dedutivo, partindo-se da constatação da hipervulnerabilidade dos titulares de dados pessoais e o legítimo desenvolvimento econômico, conclui-se que deve se chegar a um consenso harmonizando os interesses em jogo, tendo em vista a recente aprovação do Regulamento do Processo de Fiscalização e do Processo Administrativo Sancionador pela ANPD, que enfatiza a regulação responsiva.
Métrica y poética de Antonio Colinas
Authors: Martínez Cantón Clara Isabel
Published: December 2021

Antonio Colinas es una de las figuras más relevantes de la literatura española contemporánea. Poeta, narrador, ensayista, traductor y crítico, su obra abarca muchos géneros, aunque si alguno le define mejor como escritor ese es la poesía, género en el que más destaca y al que dedicamos el presente libro. Su obra ha sido reconocida con el Premio de la Crítica en 1975, el Premio Nacional de Literatura en 1982, el premio de Las Letras de Castilla y León en 1998, el Premio Internacional Carlo Betocchi en 1999 y el Premio de la Academia de Poesía de Castilla y León en 2001, entre otros. El objeto de este trabajo es estudiar un aspecto de la obra poética de Antonio Colinas que consideramos clave a la hora de entender su obra y al que quizás todavía no se le ha prestado la atención que merece: la métrica, fundamental como base productora del ritmo poemático y como elemento formal dotado de significación.
Reflexiones sobre el texto televisivo
Authors: Bastos Duarte Elizabeth
Published: December 2021

Es indiscutible la importancia de la televisión en la comunicación contemporánea, por ello es inevitable el contacto permanente con los productos televisivos. Por eso, tanto a los apocalípticos como a los integrados sólo resta analizarlos e interpretarlos, esto es, enfrentar las innumerables dificultades que esa tarea implica, pues el aparato teórico y metodológico de que se dispone se muestra muchas veces insuficiente e inadecuado a la complejidad e hibridación que caracterizan al texto televisivo. Y enfrentar ese desafío, pienso yo —a diferencia de estudios que se concentran en la investigación de los medios apenas como conductores de flujos de contenidos de diferentes órdenes o que ven los medios como meros lenguajes, cuya gramática intentan comprender— es tener presente, en primer lugar, que no se puede analizar cualquier producto mediático independientemente de su relación con el proceso que lo engendra y constituye, cuyas características particulares tienen repercusiones en sus contenidos y lenguajes.
Inmortalidad y sinequismo; hacia una semiótica de los sistemas religiosos
Authors: Tenório dos Santos Gerson
Published: December 2021

Abbagnano (1992: 684-5) advierte que hace tiempo el problema de la inmortalidad ha dejado de ser un problema vivo de la filosofía por dos razones: la primera, porque la dirección de la ética moderna ha eliminado de la moral toda dependencia de una sanción ultramundana y la segunda, porque la dirección de la filosofía moderna ha negado la eficacia del debate acerca de la inmortalidad por considerar sin sentido extender el análisis filosófico más allá de la esfera de la existencia o de la experiencia aprehensible. De acuerdo con Abbagnano, el interés por el tema se ha limitado a la esfera de la religión y de la apologética religiosa.

A Pragmatic Approach for Detecting nCOVID-19 using Pervasive Computing Based on Dual Diagnostic Measures
Authors: Biswas Swarnava , Chakraborty Chandranath , Chawla Riddhi , Paul Dabosmita , Sen Debajit , Sarkar Niloy , Mukherjee Moumita
Published: December 2021

Our regular way of life has been disrupted by the COVID-19, and we have been obliged to accept the procedures that are in place under the new normal regime. It is envisaged that the standard diagnostic technique will evolve throughout the course of the procedure. As a help to this type of diagnostic technique, our research group is developing a tool. In this article, the group discusses the importance of employing two diagnostic metrics that have proven to be pivotal in many diagnoses for doctors, and how they might be used to their advantage. Together, natural language processing-based symptoms measures and a machine learning-based strategy that takes into account medical vitals can help to minimise the error percentage of detection by as much as 50%. The technique suggested in this study is the first of its type, and the authors have obtained findings that are satisfactory in terms of accuracy. A further justification for suggesting such a strategy is the manner in which a fusion algorithm might arrive at the correct results from two concurrent algorithms performing the same task. One of the group's other objectives was to give the doctor a valuable opinion in the form of such an architectural design. The suggested design may be employed at any point of care facility without the need for any additional infrastructure or escalation of the current amenities to accommodate the proposed architecture.
The strength for line bundles
Authors: Ballico Edoardo , Ventura Emanuele
Published: December 2021

We introduce the strength for sections of a line bundle on an algebraic variety. This generalizes the strength of homogeneous polynomials that has been recently introduced to resolve Stillman's conjecture, an important problem in commutative algebra. We establish the first properties of this notion and give some tool to obtain upper bounds on the strength in this framework. Moreover, we show some results on the usual strength such as the reducibility of the set of strength two homogeneous polynomials.

Mediebilledet af dansk medieforskning [Media Images of Media Research in Denmark]
Authors: Wien Charlotte
Published: December 2021

A strange relationship exists between media and journalism researchers and Danish journalists. The nature of the relationship might be described as mixed feelings based on a mutual lack of respect and knowledge between the two professions. The aim of this article is to explore this relationship. Using qualitative text analyses, I trace the media’s descriptions of research in media and journalism, and through the analyses discuss the conception and stereotypes of this research as it is reflected in the media.

My analyses show that media coverage of media research can be divided into three categories based on the roles played by media research and researchers. The first category of articles depicts media researchers as the suppliers of “facts and figures” about media performance. The second mainly describes the component of media research that analyses how the audience is affected by the media. And finally, the third category of articles addresses the research in news media and journalism.
On the educational function of administrative responsibility
Authors: Lipinsky Dmitriy Anatol'evich , Makareiko Nikolai Vladimirovich , Musatkina Aleksandra Anatol'evna
Published: November 2021

The subject of this research is the views of the scholars on classification of administrative responsibility functions and substantiation of the existence and implementation of its educational function. The research methodology employs formal legal and dialectical methods. The authors examine various classifications of the functions of administrative responsibility, analyze the role of educational function therein, and trace its correlation with the general legal functions. It is indicated that namely the educational function does not receive due attention in modern research, and its potential is underestimated. It is proven that the absence of legislative consolidation of educational purpose in the Code of the Russian Federation on Administrative Offenses is not the reason to deny the educational function of administrative responsibility. The conclusion is made that the achievement of educational goal of the administrative function of administrative responsibility is the result of a comprehensive impact of the broadest range of legal, political, economic, moral-ethical, and other means. Thorough legislative mediation of the measures of administrative responsibility, their effective application, all-round encouragement of active lawful conduct, timely informing legal entities about the capacity of administrative responsibility, and consequences of implementation of its measures, ultimately realigns legal consciousness and “removes” unlawful attitudes. The article substantiates that law-abidance is the initial goal of educational function of administrative responsibility. Legal-abidance is formed not only due to realization of the capacity of law in regulating social relations, but also the concern to suffer deprivations as a result of implementation of administrative responsibility.

Authors: Ayoub Cherif Nahar , Yakuba Abakar Yakuba , Umar Beshir Yakuba , Stanovov Evgenii
Published: November 2021

This article covers the problems of foreign policy problems faced by the Sahel countries. The research is dedicated to the peculiarities of the policy of Sahel Alliance in countering the risks and threats to regional security. The goal consists in outlining the key priorities and vectors of foreign policy of the Sahel countries. The methodological framework is comprised of the historical-comparative and historical-genetic methods, as well as content analysis of the doctrinal sources of the Sahel countries for determination of the foremost threats. This allows establishing differences between the approaches used by Chad, Niger, Mali and Burkina Faso aimed at expansion of their economic, political and military influence in the Sahel Region. The scientific novelty consists in the fact that on the basis of content analysis of UN speeches of the leaders of Sahel countries, the author examines the prioritization of threats for the four countries of Sahel Region and the desired mechanisms for their elimination. The current challenge for the Sahel countries is to simultaneously protect their people and promote development via reform for establishing lasting and stable peace in the region. At the same time, such countries as Niger, Burkina Faso, Mali, Chad and the Sahel Region overall have strengthen their strategic importance for the European foreign policy and security interests.
Correlation between psychological component of school adaptation and socioeconomic risk factors of early development
Authors: Kazakova Elena Valerievna , Sholokhova Elizaveta Nikolaevna , Sokolova Lyudmila Vladimirovna
Published: November 2021

The subject of this article is the examination of the root problems of the adverse impact of socioeconomic risk factors upon the psychological component of school adaptation of first-graders. The goal lies in establishment of correlation between the characteristics of psychological component of school adaptation of elementary school students and various socioeconomic risk factors in their early development. The research involves 284 first-graders 7-8 years of age (126 girls and 158 boys). Research methodology relies on the following materials: “House – Tree – Man” by J. Buck, “Little Houses” by A. O. Orekhova, “Faces” by N. V. Lukyanchenko, T. L. Yadryshnikov, “Ladder” by V. G. Shchur, social passport of a family. The correlation analysis reveals that the indicators of the psychological component of school adaptation, such as the level of self-esteem, emotional adaptation, depressive states, emotional background, and sense of security, are most affected by the socioeconomic risk factors of early development. The author also establishes the dependence of the characteristics of psychological component of school adaptation of first-graders on the educational background of their parents and family atmosphere. Socioeconomic risk factors in child’s life prior to school are rather related to emotional state of a child, determining the emotional well-being and success in school adaptation. Timely identification of these factors allows preventing the difficulties that may arise during the school period.
“At the Western Palace”: The Dehumanization of Whiteness, Americanness, and Chinese-Americanness in Maxine Hong Kingston’s The Woman Warrior
Authors: Szmańko Klara
Published: December 2021

The dehumanization of whiteness in Maxine Hong Kingston’s The Woman Warrior (1976) inheres in the overarching ghosthood metaphor. While first generation Chinese American immigrants in The Woman Warrior attribute the power of transforming people into ghosts to the United States of America as a country, the questioning of a person’s humanity by calling them a “ghost” is not reserved for white people alone. Chinese American immigrants also run the risk of losing their humanity and becoming ghosts if they renounce their relatives and their heritage. The husband of the first-person narrator’s Chinese aunt, Moon Orchid, is an example of a Chinese American man, who turns into a ghost on account of swapping his Chinese wife for a much younger American one. The clinic in which Moon Orchid’s husband works, a chrome and glass Los Angeles skyscraper, becomes a vehicle for the metaphoric representation of the United States as the Western Palace – also the title of the fourth of the five chapters of The Woman Warrior, exemplifying narrative techniques employed by Kingston in order to render the above mentioned dehumanization.
From the transverse field Ising chain to the quantum E8 integrable model

Published: December 2021

This review reports a series of theoretical and experimental progress on researches of the transverse field Ising chain (TFIC) and the quantum E8 integrable model. For the TFIC, on one hand, a unique exotic quantum critical behavior of Grüneisen ratio (a ratio from magnetic or thermal expansion coefficient to specific heat) is theoretically established; on the other hand microscopic models can accommodate the TFIC universality class are substantially expanded. These progresses successfully promote a series of experiments collaborations to first-time realize the TFIC universality class in quasi one-dimensional anti-ferromagnetic material BaCo2V2O8 and SrCo2V2O8. For the quantum E8 integrable model, the low temperature local dynamics and the dynamical structure factor with zero transfer momentum of this system are analytically determined, where a cascade of edge singularities with power-law divergences are obtained in the continuum region of the dynamical structure factor. After combining with detailed quantum critical scaling behaviors analysis and large scale iTEBD calculation, it successfully facilitates a series of experiments, including THz spectrum measurements, inelastic neutron scattering and NMR experiments, to realize the quantum E8 integrable model in BaCo2V2O8 for the first time. The experimental realization of the quantum E8 integrable model substantially extends the frontiers of studying quantum integrable models in real materials. The series of progress and developments on the TFIC and the quantum E8 integrable model lay down a concrete ground to go beyond quantum integrability, and can inspire studies in condensed matter systems, cold atom systems, statistical field theory and conformal field theory.
Correlations between Case and the D-system and the interpretability of Case
Authors: Martin Txuss , Sitaridou Ioanna , Hinzen Wolfram
Published: December 2021

A correlation between articles and Case has long been noted based on diachronic evidence. Beyond articles, evidence supports that this correlation extends further to clitics and the determiner system (the D-system) at large. The D-system in turn supports referential functions in grammar and is closely correlated to Person. The aim of the present article is to link support for these facts to the broader foundational question and independent recent theories of the function of Case as governing referential meaning in grammar at the level of clauses. This link is supported by specific evidence from the use of Accusative and Partitive clitics in Romance, which play the same roles strong Accusative vs. weak Partitive Case play in Finnish, which lacks articles, and similar patterns in languages such as Turkish, Russian, and Latin. Case therefore arguably determines the referential function of (pro-) nominals as part of event structures, whether synthetically or else analytically via the left periphery of the NP. This explains the historical links between Case and the D-system, which we further argue evidence from Greek has been incorrectly argued to contravene.
Understanding the Failure of the Arab Maghreb Union: A Critical Constructivits Account
Authors: Dursun Hatice Rumeysa
Published: December 2021

The Arab Maghreb Union (AMU), which was established by the countries of the region known as North Africa, also called as the Maghreb, to strengthen regional cooperation, draws attention as an organization that has lost its effectiveness today. This study examines the factors that affect the "failure" of the AMU. The discussions for the AMU to gain an active structure, which was established with the participation of Morocco, Tunisia, Algeria, Mauritania and Libya in the late 1980s, have increased even more with the current political crisis in Libya. The idea of "a united Maghreb" was actually a political argument used to mobilize the people of the region against the colonial powers during their struggle for independence long before the establishment of the AMU. Many reasons can be put forward to explain why the leaders of the region, who used the idea of creating a "united Maghreb" in their discourses, did not show enough will to achieve this dream. This study uses a critical constructivist account of state identity and interest and argues that Maghreb states were not able to develop shared identities and interests. It argues that the creation of the AMU could not pave the way for regional cooperation because Maghreb states consider each other as rivals and articulated their interests on this conception.

Published: December 2021

Support vector machine (SVM) is a robust machine learning method and is widely used in classification. However, the traditional SVM training methods may reveal personal privacy when the training data contains sensitive information. In the training process of SVMs, working set selection is a vital step for the sequential minimal optimization-type decomposition methods. To avoid complex sensitivity analysis and the influence of high-dimensional data on the noise of the existing SVM classifiers with privacy protection, we propose a new differentially private working set selection algorithm (DPWSS) in this paper, which utilizes the exponential mechanism to privately select working sets. We theoretically prove that the proposed algorithm satisfies differential privacy. The extended experiments show that the DPWSS algorithm achieves classification capability almost the same as the original non-privacy SVM under different parameters. The errors of optimized objective value between the two algorithms are nearly less than two, meanwhile, the DPWSS algorithm has a higher execution efficiency than the original non-privacy SVM by comparing iterations on different datasets. To the best of our knowledge, DPWSS is the first private working set selection algorithm based on differential privacy.

Background

The benefits of probiotics being used in animals are well-documented via evidenced growth performance improvement and positive modulations of gut microbiota (GM). Thus, a combination of effective microorganisms (EM) has been frequently used in animal production, including broilers. However, there are only very limited reports of EM on the growth performance and the modulation in GM of partridge shank broiler chicks.

Methods

We attempted to evaluate the effects of a basal diet with the addition of an EM mixture on the growth performance and gut microbiome of the chicks. A total of 100 ten-day-old female partridge shank broiler chicks were randomly divided into two groups of 50 chicks each, of which, one group fed with EM supplementation in the basal diet (designated as EM-treated group), the other group just fed with a basal diet (referred as to non-EM treated group or control group). The body weight, daily feed intake, daily gain, feed conversion ratio and other growth parameters were observed and compared between EM-treated and non-EM-treated chicks, and the gut microbiota was profiled by 16S rRNA-based next generation sequencing (NGS).

Results

EM-treated chicks showed significantly increased performances in body weight (BW), average daily gain (ADG) and reduced feed conversion ratio (FCR). Histological observation indicated that dietary supplementation of EM significantly increased the villus heights (VH) and the ratio of villus height to crypt depth (VH/CD), while decreased the CD of jejunum, ilea, and ceca. The results of 16S rRNA-based gut microbiota analyses showed thatFirmicutesaccounted for the most of the relative abundance (63.24%∼92.63%), followed byProteobacteria(0.62%∼23.94%),Bacteroidetes(0.80%∼7.85%),Actinobacteria(0.06%∼13.69%) and others in both EM-treated and non-EM-treated broiler chicks. The addition of EM could not alter the alpha diversity of gut microbiota. Compared with the non-EM-treated chicks, the abundances of bad bacteria in the phyla ofFirmicutes,Euryarchaeota, andRuminococcuswere dramatically decreased in that of EM-treated chicks, while the abundances of good bacteria in the phyla ofActinobacteriaandWPS-2were significantly increased.

Conclusions

The supplementation of EM in feed could improve the growth performance and positively influence the morphological characteristics of the intestine, and ameliorate the community and structure of the intestinal microbiota of partridge shank broiler chicks.

Present study entitled was carried out in field irrigation lab, Department of Agricultural Engineering, Aditya Engineering College, Surampalem. In the present experiment locally available agricultural substrate paddy straw, sugarcane bagasse and cocopeat were tested with black soil and farm yard manner as casing materials. For parameters such as days required for spawn run, pinhead formation, harvest days, total yield and biological efficiency were determined. Significant results were obtained for all the experimental parameters and also for the stem length and cap diameter. Best substrate found was the paddy straw in the recent experiment with days required for spawn run (14 days), pin head formation (11.2 days), days for first harvest(50 days), stem length (8.07 cm), capdiameter (8.67 cm), first harvest (489.45 gm), second harvest (453.68 gm), total yield (925.24 gm), biological efficiency (94.31%). The next best in the order was coco peat followed by sugarcane bagasse. Hence this study confirms the suitability of paddy straw for cultivation to mushroom growers and farmyard manure with 15 cm casing thickness as substrate for its cultivation for achieving higher yield. The benefit cost ratio was estimated as 1.57.

Background: Chronic pleural empyema (CPE) is the last phase of the triphasic process of pleural empyema development. Lung decortication is the corner stone in management of chronic empyema. This study aimed to objectively evaluate the efficacy of conventional decortication operation in chronic pleural empyema in adult patients. Also to prove that decortication of variable sizes of chronic empyema thoracis lesions is followed by improvement considering respiratory impairment.

Methods: This prospective clinical study was conducted on 103 patients undergoing elective lung decortication operation for management of chronic empyema. All patients were subjected to the history taking, general examination, chest examination, computed tomography (CT), pulmonary function test and arterial blood gases. Postoperative evaluation was done in outpatient clinic 6 months post operatively including: Full clinical examination, investigations (acute phase reactants, CT chest, PFT and arterial blood gases.

Results: Total leucocytic count, ESR 1st hour, ESR 2nd hour and CRP were significantly decreased in post than pre. FEV1 and FVC were significantly increased in post than pre (P <0.001). FEV1 / FVC Ratio was significantly decreased in post than pre (P <0.001). Transverse and antero-posterior diameters of affected hemithorax were significantly increased in post than pre (P <0.001, 0.019 respectively). Transverse and antero-posterior diameters of normal hemithorax were insignificantly different between post and pre. PaO2 and SpO2 were significantly increased in post than pre (P <0.001). PaCO2 was significantly decreased in post than pre (P <0.001).

Conclusions: The improvement in the lung function, arterial blood gases, transverse and antero-posterior diameter of affected and normal hemithorax was proposed to have resulted from the decortication in chronic empyema thoracis. Decortication of variable sizes of chronic pleural empyema lesions is followed by objective improvement considering respiratory impairment.

Emergency Department (ED) visits result from urgent conditions and instances caused by disease, disaster, accidents, or injury and require immediate medical attention. Today, emergency dental services are becoming an integral and crucial facet of properly functioning healthcare systems. Dental emergency visits are a risky undertaking when the COVID-19 epidemic is decimating global health systems. Emergencies in dental care are possibly life-threatening occurrences and demand instant attention to curb infection, severe pain, and tissue bleeding. Examples of these conditions include trauma affecting different facial bones, bacterial infection on soft tissues or cellulitis, and uncontrolled bleeding. Today, given the implications of the COVID-19 pandemic, all providers need to use their professional judgment to determine the need for emergency or urgent care for a patient. Consequently, this systematic review of literature reviews the implications of the COVID-19 epidemic on the use of dental services in different care facilities across the nation.
