The Route of Administration of Rabies Vaccines: Comparing the Data
Authors: Briggs Deborah J. , Moore Susan M.
Published: June 2021

Cell culture rabies vaccines were initially licensed in the 1980s and are essential in the prevention of human rabies. The first post-exposure prophylaxis (PEP) vaccination regimen recommended by the World Health Organization (WHO) was administered intramuscularly over a lengthy three-month period. In efforts to reduce the cost of PEP without impinging on safety, additional research on two strategies was encouraged by the WHO including the development of less expensive production methods for CCVs and the administration of reduced volumes of CCVs via the intradermal (ID) route. Numerous clinical trials have provided sufficient data to support a reduction in the number of doses, a shorter timeline required for PEP, and the approval of the intradermal route of administration for PEP and pre-exposure prophylaxis (PreP). However, the plethora of data that have been published since the development of CCVs can be overwhelming for public health officials wishing to review and make a decision as to the most appropriate PEP and PreP regimen for their region. In this review, we examine three critical benchmarks that can serve as guidance for health officials when reviewing data to implement new PEP and PreP regimens for their region including: evidence of immunogenicity after vaccination; proof of efficacy against development of disease; and confirmation that the regimen being considered elicits a rapid anamnestic response after booster vaccination.

Surveys showed that vaccine hesitancy may influence the acceptance of COVID-19 vaccines in healthcare workers (HCWs) and the general population. Currently, the actual acceptance of COVID-19 vaccination in HCWs has rarely been reported. In the present survey, we investigated the real-world acceptance of COVID-19 vaccination in HCWs in perinatal medicine during the first three-month period of vaccination in China and to identify the main reason for the decline of vaccination. HCWs (1087) who participated in a Chinese national symposium on perinatal medicine during 16–18 April 2021 were invited to answer a 27-question questionnaire online. A total of 1051 HCWs completed the questionnaire. Of them, 86.2% (906/1051) accepted the COVID-19 vaccination and 13.8% (145/1051) declined the vaccination. Because of the vaccine hesitancy, one-fourth of the vaccinated participants did not accept the vaccination until consulted with others or requested by employers. The main reason for the decline of vaccination in 145 unvaccinated HCWs was the concern about vaccine safety. The results indicate that vaccination request by employers may promote vaccine acceptance. More convincing data on the safety of COVID-19 vaccines appears to be important to increase the acceptance of vaccination.
Haline Convection within a Fresh-Saline Water Interface in a Stratified Coastal Aquifer Induced by Tide
Authors: Ben-Zur Elad , Gvirtzman Haim , Shalev Eyal
Published: June 2021

Sea-tide effects on the fresh-saline water interface (FSI) in a stratified coastal aquifer are examined through laboratory experiments. The physical model, a two-dimensional rectangular flow tank, is filled with layered aquifers and aquitards. The aquifers serve as the main entrances/exits of water to/from the system through significant horizontal flows, creating unstable conditions of heavier saline water above lighter freshwater for short periods of time. Several processes create mixing; this instability results in haline convection, creating downward fingering, stable rising of horizontal saltwater front, and unstable upward fingerings of flushing freshwater. The time lag between the sea tide fluctuations and the emergence of adequate fresh- and saltwater is higher in a stratified system compared to a homogeneous system. Furthermore, longer tide cycles lead to the enlargement of the FSI’s toe horizontal movement range. The combination of tidal forcing with a layering aquifer structure leads to a wider FSI by creating a significant salt- and freshwater mixing inside each layer, vertical flows between the layers, and saltwater bodies at isolated areas. Haline convection within the FSI might be the reason for the wider fresh-saline interfaces that are found in field studies.

Authors: ElGhanam Eiman , Hassan Mohamed , Osman Ahmed , Ahmed Ibtihal
Published: June 2021

Recently, electric vehicles (EVs) have been introduced as an alternative method of transportation to help mitigate environmental issues, such as carbon emissions and fuel consumption, caused by conventional transportation systems. The implementation of effective EV charging systems is essential to motivate mass adoption of EVs. Accordingly, fast and reliable communications between the charging systems and the EVs are vital for efficient management of the charging process. Different radio access technologies (RATs) are discussed in the literature to enable communication between the highly mobile EVs and the charging subsystems, to collect and exchange information such as state of charge (SoC), users’ locations, and charging decisions between the different network entities. This information can be used to coordinate charging plans and select the optimal routes for moving vehicles. This paper presents a survey of existing literature on vehicular communications for EV charging coordination and management. The communication requirements and feasible communication technologies for vehicular communication are first discussed in details. A review of the physical layer security strategies is then presented and the role of the different RATs in EV charging coordination and management is described and studied.

Published: June 2021

Inflammatory processes accompanied by a sore throat are a widespread symptom of both infectious and non-infectious genesis. In this case, topical therapy with medications that combine anti-inflammatory and analgesic effects, in the form of comfortable dosage forms — sprays, is the most effective. In this case, the used drug has a complex effect on contact tissues, due to both the actual pharmacological activity of the pharmaceutical substance and the physico-chemical properties of the excipients forming the dosage form. A study of the release of the active substance from sprays in the perspective of their topical application, as well as their osmotic activity in an in vitro experiment that simulates the process of application to the throat mucosa, was carried out. The real influence of the osmotic activity of the dosage form on the degree of release of the active substance due to the multidirectional nature of the resulting diffusion flows is shown.

The sharing economy platforms in the accommodation, such as Airbnb, gain more public attention. Several hoteliers in Indonesia have complained about the unequal playing of the field due to the alleged tax violations. Some studies on the impact of Airbnb have been discussed in various countries, but this subject has not been widely conducted in Indonesia. This study aims to determine the impact of Airbnb on the conventional hotel industry in Bali and how the conventional hotel’s  response to compete with Airbnb. This research was conducted using qualitative research. Data was collected through interviews and secondary data collection. Interviews were conducted with representatives of hoteliers, Airbnb owners, and hospitality associations in Bali. Using forecasting analysis, this study finds that the presence of Airbnb in Bali has an impact on the occupancy rate of conventional hotels in Bali. However, there doesn't a significant impact from Airbnb regarding the hospitality revenue. Meanwhile, conventional hoteliers generally do not make particular efforts to compete with Airbnb. This research implies for the managerial side of hotels and public programs and policies, especially for the Government of Bali in the future to pay attention to consumer protection to provide equal action between conventional hotel and Airbnb owners.

Interpersonal communication versus building priestly community
Authors: Smoleń Jerzy
Published: June 2021

Building real priestly community without proper communication style is impossible. Accurate and good interpersonal relationships resulting from the act of communication raise up hope and give courage to concern for the development and the quality of the functioning of specific community. They also become the motivating influence in taking actions to deal with own development and with self-actualisation through cooperation. Everyday life shows that there are certain elements which impede building satisfactory priestly community. Crises, shocks, disasters which are a part of our life also affect priestly community. The article shows research results which present significant elements of interpersonal communication impeding and facilitating building communities, in my opinion, not only priests.

The text analyzes the category of dialogue and meeting in the pedagogical thought of Józef Tischner in a particular way. The conclusions presented contained here are a continuation and deepening of the research presented in the monographic work “Pedagogical and religious concepts od Józef Tischner. In search of a new model of religious education”. The main thesis of the article is to indicate the fundamental role, place and meaning of the category of dialogue and meeting in the structure of educational content emerging from the concept of the philosophy of drama. At the outset, the general assumptions of Tischner's philosophy are outlined in order to indicate the context of educational analyses which constitute  analyzes that make up the drama pedagogy project. On this basis, the categories of dialogue, dialogicality and meeting  are presented in detail. These categories play a very important role in development and creative processes. The thesis of the position presented here is the recognition that the work of Józef Tischner not only provides valuable hints in contemporary education, but also designs positive solutions that may contribute to the creation of new models and strategies of educational work, and to good educational practices in their space. On the 90th anniversary of the author's birththere is a special occasion to verify the thesis put forward in this way.

Published: June 2021

For any industrial entity put into operation, it is of interest to its ability to fulfil its mission under certain conditions, at a given time or during a given period of time, assuming that the means of maintenance are provided. This represents availability and is a complex form of system / product quality, as it includes both reliability and maintainability. Availability can be increased by: maximum reliability, maintenance, respectively by maximum maintainability, correct use of equipment / machines, renewal, optimization of reliability and maintainability characteristics, but provided that such balancing does not lead to contradictory solutions. The availability of a product will be higher the more reliable it is and requires less maintenance. It should be borne in mind that in order to ensure a certain level of reliability, maintenance costs must not exceed 10...20% of the purchase price of the product each year [1]. Restoration of reliability to a normal level is achieved through corrective or preventive maintenance. In practice, a compromise is sought between the purchase price, the service imposed and the accepted risk, as in order to achieve availability through reliability, very reliable parts must be used, which cost 5-10 times more than usual [2]. Maintenance-based availability results from the consideration that reliability is a probability of trouble-free operation over a period of time. Reliability is technically and financially limited. Defects in the initial period of operation of the product, as well as those in the final period derive from inevitable physical phenomena, and defects in the maturity period have a normal accidental character. In addition, the reliability can deteriorate over time even during storage, thus causing additional damage. Reliability is restored to its normal level through corrective or preventive maintenance, as failures are foreseeable or unpredictable. Product availability is the result of a combination of reliability and maintainability and they support each other. Increasing the maintainability of products leads to increased availability. In this case, the real maintainability of a burning oven of a cement factory was studied, with the aim of finding practical solutions to increase the service life. Achieving the proposed objective required monitoring the operation / failure of such equipment for nine months and statistical processing of the information obtained.

Authors: ISTRATE Gina Genoveva , MUREȘAN Alina Crina
Published: June 2021

In this paper the corrosion behavior of different materials has been evaluated based on exposure in seawater. The laboratory immersion test technique has been applied to evaluate the effect of seawater on the corrosion behavior of different materials. In three sets of experiments, carbon steels (A681 Type O7), austenitic stainless steels (316L) and aluminium alloys (Al5083) were utilized. The specimens were fixed fully submerged in seawater. The corrosion process was evaluated using weight loss method, open-circuit potential measurements (OCP) and polarization techniques. To determine gravimetric index and the rate of penetration, samples were immersed in corrosive environment for 89 days and weighed periodically. The electrochemical experiments were conducted with a Potentiostat/Galvanostat (PGP 201) analyzer. It was connected to a PC. The Voltamaster software was used for electrochemical data analysis. A three-electrode cell composed of a specimen as a working electrode, Pt as counter electrode, and saturated calomel electrode (SCE) (Hg (l)/ Hg2Cl2 (s)) as a reference electrode were used for the tests. The weight loss tests revealed the lowest corrosion rate values for stainless steel and aluminium alloys, indicating a beneficial use for these materials in marine environments. The potentiodynamic method shows that the lowest corrosion rate in seawater (2.8 μm /year) was obtained for the Al5083 alloy, and the highest value of the corrosion rate (41.67 μm/year) for A681 carbon steel.

In order to provide the basis for the application of scientific and technological advances, reorganizing shrimpfarming in sustainable and bringing high economic value to the Mekong Delta. The study surveyed the current situation of breeds, farming methods, environmental monitoring control, Vibrio sp. and the use  of probiotics of shrimp farmers in the Ca Mau peninsula by interviewing 200 shrimp farmers and 20 specialized fisheries officers in Ca Mau, Soc Trang, Bac Lieu and Kien Giang provinces. The results showed that the shrimp breeds selected for farming originated from the Central and Southwest provinces. There are four popular farming methods: intensive, semi-intensive, improved extensive, and rice-shrimp. The intensive farming had the highest rates of the initial quarantine of shrimp postlarvae (74%) and Vibrio test (57%). All shrimp farmers workingon the intensive and semi-intensive farmings used probiotics. The rates of probiotic use in the improved extensive and riceshrimp farmings were lower, only 60% and 40% respectively. The results suggested that shrimp farmers working on the semi-intensive and intensive farmings paid more attention to the use of probiotics as well as the test to prevent the disease in shrimp.

A análise polínica de produtos da colmeia é uma das linhas de atuação do Grupo de Pesquisa Insecta desde o ano 2000, com resultados promissores e inserindo na pesquisa científica relacionada à melissopalinologia alunos de iniciação científica, mestrado e doutorado, além de pós-doutorandos. O grupo conta com publicação em periódicos nacionais e internacionais, onde são divulgados resultados de estudos de fontes poliníferas e nectaríferas exploradas por abelhas sociais como Apis mellifera Linnaeus, 1758 e Meliponini (Melipona spp.), sendo a identificação da flora explorada por estas abelhas, realizada em sua maioria por meio de estudos palinológico dos produtos da colmeia. O livro “Atlas polínico de plantas de interesse apícola/meliponícola para o Recôncavo Baiano” é resultado de um amplo espectro de estudos relacionados à análise polínica de produtos da colmeia de abelhas sociais realizado pelos autores, especialmente os projetos de iniciação cientifica e mestrado desenvolvidos no período de 2005 a 2009, que contribuíram de forma expressiva para coleção de referências de grãos de pólen (palinoteca) de plantas de interesse apícola e meliponícola do Núcleo de Estudo dos Insetos da Universidade Federal do Recôncavo da Bahia. A apresentação da descrição polínica de táxons das principais famílias apontadas como potenciais para apicultura e meliponicultura na região do Recôncavo Baiano, contribuirá na identificação de tipos polínicos em produtos da colmeia em estudos futuros. Comumente, estudos relacionados à identificação da flora visitada pela abelha a partir de seus produtos (mel, pólen apícola, samburá, própolis e geoprópolis) utilizam a análise polínica. Porém, a identificação dos tipos polínicos (conjunto de grãos pólen) é um trabalho que requer treinamento, conhecimento e dedicação, sendo necessário consultas a palinoteca (coleção de grão pólen de referências), atlas e catálogos polínicos, bem como outras publicações pertinentes. Nesse sentido, este livro apresenta um conteúdo relevante e que pode auxiliar muitos trabalhos de pesquisa, contribuindo para identificação da flora visitada por abelhas sociais, especialmente no Recôncavo Baiano.10.35587/brj.ed.0000891
Muslim Women’s Experiences of Higher Education in Britain
Authors: Ahmad Fauzia
Published: June 2021

I explore British South Asian Muslim women’s experiences of higher education and how it impacts identity construction and negotiation. Through semi-structured interviews with thirty-five undergraduate and post-graduate Muslim female university students, I reflect on their perceived and actual experiences. By stressing how representations of them influence their participation and experiences, I analyze how individual subjectivities are mediated and negotiated while reflecting common experiences. I also consider their accounts of the social and personal benefits they felt that they gained during their studies, as well as to the more disturbing and racialized aspects of their experiences. They differentiated between three overlapping forms of beneficial experience: academic, social, and personal. While instances of anti-Muslim racism were rare or subtle, certain university structures and expectations of what being a mainstream student means often contributed to a noted sense of “othering.” I conclude by highlighting how their accounts of their university experiences directly challenge those stereotypes that misrepresent educated Muslim women as “religious and cultural rebels.”
American Muslim Women and Cross-Gender Interaction on Campus
Authors: Mir Shabana
Published: June 2021

This article is based on a study of American Muslim undergraduate women’s identity construction via gendered behavior in university spaces. I conducted the study in 2002-03 at two private East Coast universities. My research questions centered upon the religious, ethnic, gender, and cultural/racial identities of American Muslim female undergraduates. I was also interested in the nature of pluralism at American college campuses; I believed that an interesting test of this pluralism would be to see how hospitable it was to the development of American Muslim women’s identities.
A THEMATIC CLASSIFICATION OF RELIGIOUS-CHRISTIAN VOCABULARY OF RUSSIAN-UDMURT DICTIONARIES BY G. Ye. VERESHCHAGIN
Authors: Ivshin Leonid Michaylovich
Published: June 2021

The article examines the vocabulary of religious-Christian content in the handwritten Russian-Udmurt dictionaries by the first Udmurt writer and outstanding scientist, educator and missionary, clergyman G. Ye. Vereshchagin. There is no exact information about the time when the manuscripts were written. One of them was presumably created at the end of the 19 - beginning of the 20 centuries, before the adoption of the Russian spelling reform in 1918, since the letter ъ is inconsistently encountered at the very beginning of the dictionary in lexemes ending in a hard consonant. Another manuscript can be dated to the period after the adoption of the Russian spelling reform, when the Cyrillic letters ѣ, ө and ъ were excluded from the Russian alphabet. The author of the manuscripts selected appropriate primordial Udmurt equivalents to words of religious content or used borrowings (mainly from the Russian language), and was guided by the following considerations: 1) he used Udmurt words that arose in the depths of paganism, which by the time the manuscripts were compiled had acquired a completely Christian meaning (Kyldysin tӧre 'Archangel'); 2) adapted concepts that had a slightly different, everyday meaning (viz sonany, gavyldyns, aldans ‘to tempt’); 3) terms without direct correspondences in the Udmurt language are often translated by a combination of words or interpretation (umoytem Inmar vyle veras ‘blasphemer’); 4) borrowed from Russian or other languages (Archirey, Arquerey ‘Bishop’). The study of the lexical and semantic features of written attestations in the context of developing the national corpus of the Udmurt language and filling it with not only absolutely new, but also to some extent forgotten and revisited elements is a very important linguistic activity. The linguistic actualization of religious vocabulary contributes to the recovery of speech assets and registers in a significant number of dictionary nominalizations by designating concepts and phenomena of the spiritual and religious sphere of the Udmurt language.
THE NAMES OF BERRIES IN THE KOMI-PERMYAK LANGUAGE OF THE LATE 18th CENTURY (ON THE MANUSCRIPTS OF ANTONY POPOV)
Authors: Ponomareva Larisa Gennadievna , Gaidamashko Roman Valentinovich
Published: June 2021

The article deals with fifteen Komi-Permyak names of berries noted at the end of the 18th century: ди́каꙗ ка́лина [díkaya kálina] ‘elderberry (Sambucus racemosa L.)’, е́жевика [ézhevika] ‘European dewberry (Rubus caesius L.) (?)’, же́лнегъ [zhélneg] ‘rose hip (Rosa L.)’, жи́молость [zhímolost'] ‘honeysuckle (Lonicera L.)’, жо́ [zhó] ‘viburnum (Viburnum L.)’, л ѣ ́ мъ [lém] ‘bird cherry (Prunus padus L.)’, мы́рпонъ [mýrpon] ‘cloudberry (Rubus chamaemorus L.)’, на́мыръ [námyr] ‘stone bramble (Rubus saxatilis L.)’, о́зъ [óz] ‘strawberry (Fragaria L.)’, пу́лъ [púl] ‘cowberry (Vaccinium vitis-idaea L.)’, ря́бина [ryábina] ‘rowan (Sorbus L.)’, сэ́тэръ [séhtehr] ‘currant (Ribes L.)’, с ѣ ́ ́ла о̀зъ [séla òz] ‘creamy strawberry (Fragaria viridis (Duch.) Weston)’, ту́ри моль [túri mol'] ‘cranberry (Vaccinium subgen. Oxycoccus (Hill) A. Gray)’, э́мидзь [éhmidz'] ‘raspberry (Rubus idaeus L.)’. The research is based on the material of two handwritten Komi-Permyak-Russian dictionaries (alphabetical and thematic) of 1785 authored by the archpriest of the Peter and Paul Cathedral in Perm Antony Popov (1748-1788). The purpose of this study is to establish the history, etymology and ethnocultural features of the Komi-Permyak names of berries noted in A. Popov’s manuscripts. Among the methods and approaches used in this study: a) methods of historical knowledge; b) the empirical method; c) methods and techniques of comparative historical and comparative linguistics. The names of berries from A. Popov’s dictionaries are compared with the material of other later sources on the Komi-Permyak language, and are also compared with the data of the Komi-Permyak literary language and modern Komi dialects. The ethnolinguistic data and versions about the origin of all the considered Komi-Permyak words are given. Etymological analysis has shown that the native names of berries originated in ancient times, most of them belong to the pre-Permic (Finno-Permic, Finno-Ugric, Uralic) era; also there is a possible substrate heritage. Some words have lost the ability to be used independently, while others can now be classified as archaisms, dialectisms, and passive vocabulary.
FUTURUM-EXACTUM: A VERB FORM OF WRITTEN VEPSIAN THAT IS NOT TAKEN INTO ACCOUNT IN ITS DESCRIPTIONS
Authors: Kuznetsov Maxim Yuryevich
Published: June 2021

The article discusses the use of an analytical verb form of the linneb tehtud type in written Vepsian, that consists the 3 person singular form of the verb linneb ‘will’ and the passive past participle on -tud/-dud (in most cases) and is a calque from a similar Russian construction будет сделан (-a, -o). The relevance of the research is determined by the need to bring the information in the grammatical descriptions of the written Vepsian language in line with the real picture of the functioning of the Vepsian written norm, and to more accurately codify this idiom as written. The material is the texts in different styles originally written in Vepsian (journalistic) or translated into it (legal, artistic). The research confirms the hypothesis of the existence of an analytical verb form in the written Vepsian language that is not taken into account by grammatical descriptions, analyzes the detected examples of its use, and reveals the features of its structure and functioning against the background of closely related Finnic languages (Finnish, Votic, Ingrian). The article also discusses the place of this analytical form of written Vepsian among similar verb forms of Vepsian grammar and substantiates the non-identity of futurum-exactum to passive forms of the future tense ending in -škatas in the Vepsian language. It justifies the need for information about this verb form in future grammatical descriptions of the written Vepsian language.
