SARS-CoV-2 risk taxation model and validation based on large scale Dutch test-events

In response to the outbreak of SARS-CoV-2 many governments decided in 2020 to impose lockdowns. Although the package of measures which constitute such lockdowns differs between countries, it is a general rule that contacts between people, and especially in large groups of people, are avoided or prohibited. The main reasoning behind these measures is preventing that healthcare systems become overloaded. As of 2021 vaccines against SARS-CoV-2 are available, but these do not guarantee 100% risk reduction and it will take a while for the world to reach a sufficient immune status. This raises the question whether and under which conditions events like theater shows, conferences, professional sports events, concerts and festivals can be organized. The current paper presents a COVID-19 Risk taxation method for (large scale) events. This method can be applied to events to define an alternative package of measures replacing generic social distancing.

Pressurized housings, standardizing possibilities, opportunities and difficulties

Explosive atmospheres can be caused by gases, vapours, mists, dust, lint or fibres of flammable substance. If enough substance and air are mixed, the imminence of an explosion depends on probability and efficiency of the ignition source. Hazardous areas classified in sectors must be protected from ignition sources. Equipment and protective systems intended for use in potentially explosive atmospheres should be selected to meet the appropriate requirements for protective equipment and systems. The current paper aims to identify opportunities for standardization of pressurized equipment. The first part of the paper presents the risk of explosion associated with the presence of flammable substances and protection against explosions. The concept and opportunities of using pressurization are described in the second part of the paper. The third part refers to considerations regarding size and shape of pressurized equipment. A synthesis of pressurized equipment’s offer - dimensions, shape and functional role, is presented in the last part of the paper. Among the conclusions the existence of a gauge profile that depends on purpose, volume, operating position and assembly of the equipment, was mentioned.

Metonymies, Immigration and the Press: From Ilegales to Guiris

The current paper explores the Lexical and Conceptual Metonymies employed by the Spanish press to refer to immigrants from cognitive and critical discourse perspectives. Two corpora of news stories are analyzed: the first contains news stories from the Comunidad de Madrid, whereas the second is contextualized and geolocalized in a particular area of Madrid, Lavapiés, where several studies have revealed a tendency to use the diversity present in this territory as a marketing strategy. The analysis brings to light differences and similarities in the underlying metonymical discourse of each corpus, namely in terms of the distribution of the Conceptual Metonymies found therein, as well as their correlation with a positive, neutral or negative assessment of the given news story. The metonymical discourse of the first corpus correlates most strongly with neutral assessments, while that of the second corpus correlates largely with positive assessments of the conceptualizations.

Turkish President’s Address to The Joint Session of Pakistan’s Parliament: A Corpus Assisted Positive Discourse Analysis

Formal visits to friendly regions have grown in popularity worldwide in recent years. Heads of state addresses are analysed from a unique perspective. Positive discourse analysis of speeches by international leaders has garnered attention, particularly in Pakistan, following Turkey's president's four visits to the country over the last decade. For the fourth time, he was given the opportunity to address the joint session of parliament. Since their independence, Turkey and Pakistan have had a friendly relationship, and even before that, the people of the region fought to defend the Ottoman Empire during World War II. The people of the subcontinent were active participants in the process, pleading with the British government to maintain the Khilafat system. Very little research has been conducted on presidential speeches, particularly those delivered by Turkish leaders. As a result, the focus of this research paper is on President Erdogan's speeches to the Pakistani Parliament, delivered on November 17, 2016, and February 14, 2020. This study employs a corpus-assisted positive discourse analysis approach in which the concordance patterns obtained from the corpora have been explained in the light of positive discourse analysis. The findings of the study indicate that President Erdogan's speeches are brimming with optimistic language. He tries to establish a brotherly bond with his listeners through mutual equality, respect, love, and strategic collaboration. He seems to be convinced that it is necessary to emphasize the Islamic bond that exists between the two brotherly states. The current paper is noteworthy because it applies positive discourse analysis to Turkish leaders' speeches, broadening its application scope and enriching the research content of positive discourse analysis through a corpus-informed approach.

A Mini Review on SARS-COVID-19-2 Omicron Variant (B.1.1.529)

The current world facing unpredictable problems with different variants of COVID-19; SARS-COV-19 is a significant lung infection caused by a coronavirus. Each type has one or more alterations to distinguish from each other. The viruses, including SARS-COV-19, continuously change the genetic code (mutations) during their genome replication. WHO labelled two variants in that we are experienced with delta (B.1.617.2) variant, now recently the omicron came (B.1.1.529) with highly mutatable strikes on it. So WHO predicted it is more dangerous than previous variants because of its mutatable capability. The mutatable strikes play an essential role in transmissibility. So there is a need to evaluate threatens raised with the new variant, so scientists are working on it. Till now, South Africa noticed major cases positive for the Omicron variant. Based on recent reports, the current paper summarized different properties of the omicron variant with others, including protein structure, diagnosis, spreadability, treatment, and potency of vaccines.

An Approach For The Reconstruction of a Traditional Masonry-Wooden Building Located In An Archeological Area. Part I: Methodology

This study, presented in a pair of articles, defines a comprehensive methodological approach to the reconstruction of a traditional masonry-timber mansion building constructed in the 1880s of the Turkish house typology on Istanbul’s historical peninsula area that was intentionally demolished in 1948. A historical process research was carried out in the first stage of the study, after which ground penetration radar measurements and an archeological excavation were carried out to determine any possible remains or ruins of the structure, and the original architectural features of the demolished building were ascertained from the obtained data. The proposed stages in the current paper can be considered a comprehensive approach to the determination of the authentic properties of demolished or destroyed buildings in historical areas, given that the methodology allows for the integration of construction features obtained separately and independently through different activities, such as excavations, georadar measurements and historical surveys. The result is a versatile approach to the complete and realistic reconstruction of historical buildings.

Untraceable Authentication Protocol for IEEE802.11s Standard

In the current paper, a new handover authentication protocol for IEEE802.11s Wireless mesh networks is presented. The new protocol divides the network into a number of cells, each cell contains a number of access points and based on the concept of ticket authentication, the mesh user takes a new ticket when enters the region of a new cell which decreases the handover latency. Moreover, in the current paper, a new idea for ticket generation is proposed, called Chain Ticket Derivation Function (CTDF), which uses the concept of a chain. Using CTDF in our proposed protocol raises the level of privacy for the users. The security analysis presented in the paper showed more strengths in our proposed scheme. Two formal verification tools, AVISPA and BAN logic are used to test the proposed protocol.

Competitiveness of Female Entrepreneurs in Bulgaria

The intensive development of women’s entrepreneurship in Bulgaria arouses great interest among researchers, policy makers, institutions, and media. Therefore, the current paper aims to address some of the key issues related to this phenomenon. In particular, it attempts to reveal the prerequisites that encourage women to found and run their own business, the role of training in this process, and the important knowledge that enables women to take entrepreneurial initiatives. The study is based on data from a survey through a standardized questionnaire among 176 female entrepreneurs in the country.

Az átmenet etikája – Az előregyártott síremlék, mint önkép

The Ethics of Transition – The Prefabricated Tombstone as Identity Portrait. The present paper is part of a broader study. The broader context of the research compares and analyses the English and Transylvanian funeral rituals. My current paper examines a slice of this broader research context, identifying the problem of the funeral ritual, which has traditionally served as a transitional and linear ceremony. As such, the funeral started to transform from being a transitional ritual into a mosaic, personalized rite, by losing its transitional character. In the context of examining the social causes, the study examines how linear transitional elements are eliminated in funerals and, ultimately, how so-called existential holes appear in the funeral rituals. Keywords: self-image, post-socialist identity, tombstone, funeral

Are preschoolers expected to learn difficult science constructs? A content analysis of U.S. standards

In the current paper, we report on the recommendations for preschool science put forward in the educational standards of U.S. states. Our focus was specifically on whether educational standards recommend abstract science constructs—constructs that are difficult to learn. In Study 1, we focused on science constructs related to inquiry (i.e., activities geared towards the generation of scientific knowledge). And in Study 2, we focused on science constructs related to facts (i.e., established scientific knowledge). In each study, we developed a coding scheme to distinguish between concrete and abstract constructs and then determined the relative prevalence of each. Our findings show that preschoolers are indeed expected to learn abstract science constructs. At the same time, educational standards varied considerably across U.S. states. Implications for the field of early science learning are discussed.
