A Pragmatic Analysis of the Discourse of Humour and Irony in Selected Memes on Social Media
Authors: FUBARA SAMUEL JOSHUA
Published: June 2020

The aim of this study is to examine how memes peculiar to Nigerians on Facebook, Twitter and Instagram employ language to convey humour and irony. Memes can be aptly conceptualized as internet-based entertainment contents principally propagated through social networking and micro-blogging sites which come in varied forms like pictures and written texts, written texts that may or may not be conversational in nature, videos, animations and GIFs. This study adopts a qualitative eclectic approach in its analysis of conversational memes which served as data gathered from Twitter, Facebook and Instagram. Guided by the General Theory of Verbal Humour (GTVH), thirty (30) conversational memes were purposively selected for discussion using the guises or forms of humour as the unit of analysis on the one hand and discussions situated within empirical and theoretical postulations on the other hand. Findings from the study showed that all the reactions to the originating posts exhibit some form of incongruity and were also verbally ironical. The nature of the originating posts in line with the speech act classification were also found to be expressives and assertives. The study further revealed that three guises of humour namely sarcasm, witticism and pun were prominent in the reaction to the originating posts with sarcasm constituting the major guise of humour used while also pointing out that users on Twitter use humour more than those on Facebook and Instagram.
Speech Act of Complaining: Socio-Pragmatic study of Complaint by Moroccan EFL Learners
Authors: Laabidi Abdelfattah , Bousfiha Adiba
Published: June 2020

Complaining as a speech act can occur in every conversation even unintentionally. The use of this speech act is culture specific. The expressions and strategies used to issue a complaint vary according to context, interlocutors and to other socio-cultural variables. The present study investigates the complaint strategies of Moroccan higher education institutions’ EFL students. Data for the current study are collected from 37 second and third year students learning English as a Foreign Language (EFL) representing a population in Moroccan Higher Education embodied in Moulay Ismail University, Meknes and who have managed to answer a discourse completion test composed of five situational prompts. A quantitative design is used for the collection, the analysis and the interpretation of data. The data gathered are described and analyzed using descriptive statistics. The findings indicate that Moroccan EFL students use specific linguistic forms to make complaints regarding different social variables such as social distance, ranking and social power. They also imply that Moroccan EFL learners tend to use more indirect strategies in issuing their complaints along with some intimacy expressions that mark the specificity of the Moroccan culture as a positive politeness culture, par excellence.
Orthodontic Care in Pediatric Cancer Survivors: A Review
Authors: Fernandes Gabriela
Published: June 2020

Around 50-200 million children in the age group of 0-19 years worldwide are diagnosed with cancer every year. The success rate of eradicating childhood cancer in developing countries is around 80% depending on the stage at which it is diagnosed. The current oncological therapies of radiotherapy, chemotherapy and bone transplant have helped increase the number of pediatric cancer survivors exponentially. However, these modalities have necessitated the long term medical and dental follow-up. The various anomalies that occur in patients after the treatment affect general health like auditory defects, weight gain, precocious puberty and dental development like stunted root development, trismus, which deter the patient from leading a normal life. Since the growth of the dentition continues up to 14-18 years of age, the paediatric cancer survivors present with a spectrum of ailments from simple xerostomia to osteoradionecrosis and agenesis of teeth. The patients have the manifestations of the previous dental ailments and the deleterious effects of oncological therapy. Hence, orthodontic evaluation and therapy for these pediatric cancer survivors become essential to correct the dental deformities. The different features like mucositis, xerostomia, gingivitis that are typically seen in cancer survivors, can affect not only the length of the orthodontic treatment but also the oral hygiene of the patient in general. Hence, this review article aims to highlight the anomalies seen due to the onco-therapy, a few preventive measures that can be exercised to maintain the patient’s dental hygiene, the factors that are to be assessed prior to the commencement of the therapy and the effects of orthodontic therapy on the oral cavity.
A Rare Case of Congenital Missing Mandibular Second Molar: Report and Review of Literature
Authors: Kambalimath Deepashri H
Published: June 2020

Congenital missing permanent second molar is an extremely rare condition. Non syndromic mandibular second molar agenesis associated with other anomalies has occasionally been reported in literature, but isolated sporadic cases are rarely observed. Number of interactions between genetic and environmental factors during the process of tooth development might be the causative etiology for agenesis. This report presents an isolated case of hypodontia with absence of bilateral mandibular second molar agenesis in a healthy 18 year old female patient is presented and literature review on prevalence of most missing teeth with incidence of missing second molar in various regions of the world and in various regions of Indian continent is presented. No such case has been reported in Indian literature so far.
Supporting evidence varies for rangeland management practices that seek to improve soil properties and forage production in California
Authors: Carey Chelsea J. , Gravuer Kelly , Gennet Sasha , Osleger Dillon , Wood Stephen A.
Published: June 2020

California is increasingly investing in policies and programs that promote soil stewardship on natural and working lands as a way to help achieve multiple goals, including improved forage production and climate change mitigation. To inform the growing expectations for rangeland management activities to promote such services, we conducted an evidence synthesis assessing how four commonly suggested practices (silvopasture, prescribed grazing, compost application and riparian restoration) affect a suite of soil properties and plant-related metrics throughout the state. We extracted data on soil properties that are potentially responsive to management and relevant to soil health. We also extracted data on aboveground forage production, forage nitrogen content and herbaceous species richness. Our search resulted in 399 individual soil observations and 64 individual plant observations. We found that the presence of oaks had the largest effects on soil properties, with soil organic carbon, microbial biomass and other measures of soil fertility increasing beneath oak canopies. The presence of grazing increased compaction and total nitrogen, and decreased pH. Compost applications did not significantly affect any of the measured soil properties, but did boost forage production. Due to a lack of published data, we were unable to characterize the influence of rangeland riparian restoration on any of the soil or plant metrics in our review.
2018. gada latviešu metālmūzikas albumi
Authors: Gusāns Ingars
Published: June 2020

The aim of the study is to describe metal music albums of the year 2018 from the genre, textual and artistic aspects, looking for the common and diverse in the Latvian metal music world.
It is recognised that there is still no unified collection of Latvian rock and metal music resources, and that makes the researcher’s work more interesting.
Even though only ten metal albums came out in 2018, their metal styles are quite wide-ranging from symphonic metal and through thrash, groove, industrial metal to classic heavy metal, which is also played in an acoustic format.
Album designs, in the author’s opinion, are classic but qualitative and do not damage the first impression, especially designs of those albums that were released on physical media.
Because physical media is becoming an exclusive case, the trend continues to sell albums only in digital format (at least at first); this has been done by the bands “Revelation Attic”, “Yomi”, “Seira”, “NUVO”.
Perhaps knowing that Latvia is too small to live on music only, as well as wishing to expand their audience and be noticed abroad, the 5 of the albums in question are recorded in English.
The debuts of several newly formed bands (“Seira”, “Revelation Attic”, “Māra”) confirm the unlost interest in metal music and also show the attempts of these groups to build their way to Latvian and the world metal music scene, which manifests in their search for a strange sound (“NUVO”) or a strong female vocal use (“Oceanpath”, “Seira”, “Māra”).
In general, Latvian metal music representatives continue the world’s metal music traditions, where it is extremely difficult to surprise because the number of existing bands is so large that it is almost impossible to be original, while the population of the planet is so big that many bands can access the listener so that each band also searches for its audience, both online and in concerts.

The purpose of this study was to determine the application of thematic learning with scientific approaches and learning outcomes of class IA students of SD Inpres Ende 7. The type of research used was classroom action research with data collection techniques namely observation techniques, and tests. The results showed that the teacher's activity in the first cycle was not optimal in fostering new experiences that were meaningful and more dominant use of time to discuss themes mathematically, not optimal in making general phenomena available to later draw specific conclusions (inductive reasoning) or otherwise specific phenomena later draw conclusions as a whole (deductive reasoning). Learning outcomes are 36, 36%. In the second cycle there was an increase in teacher and student activities and 100% completeness, with an average of 78.18. It is concluded that thematic learning provides a charge for students to have comprehensive thinking skills (multi aspects), having a rational and empirical relationship. Scientific approach (scientific approach) provides space for students to observe, ask, try, process, present, conclude, and create. Thus students will use the skills to investigate and or inquiry against a phenomenon or symptoms. It is recommended to teachers to optimize the stages of thematic learning with a scientific approach to familiarize students wit
Organizational innovations of the integrated management system for hospitality and tourism companies
Authors: KOVTUNENKO Kseniia , BAILIUK Yuliia
Published: June 2020

Organizational innovations of the integrated management system for hospitality and tourism companies is now an essential factor in the economic competitiveness of firms. The study of innovations in the service sector is still in its infancy, as the first studies did not appear until the late 1990s, and it is difficult to find a reliable theoretical basis for studying innovations in this sector. It becomes even harder to find when applied to firms working in the hospitality and tourism sectors. Tourism is currently one of the most promising industries in the world, and there is an urgent need for a better understanding of innovation in this sector.
This study addresses a common question: how to explain innovations in the tourism sector. In seeking an answer to this question, the work has two objectives: 1) to discuss what innovation in services is, taking into account a study of innovation in hospitality and travel firms, along with a literature review; 2) to develop a case study for an international group on hospitality.
The results support the hypotheses that the implementation of an Integrated Hotel Management System is an important innovation in the sense that it mainly promotes organizational innovation, while firms use sustainable development policies as strategies of innovation and differentiation from competition. At this time, tourism firms are to be managed in three ways: economic, social and environmental. The advantages defined by the hotel are: optimization of work processes, with an impact on productivity, sustainable development of the company, strengthening of its corporate image, creation of an organized structure, reduction of environmental impact and risks inherent in the activity, and increase in customer satisfaction. Finally, we present a number of conclusions that allow a better understanding of innovation in tourism and are aimed at expanding the theoretical debate as well as knowledge on this topic.
Overtourism and tourismphobia
Authors: Veríssimo Medéia , Moraes Michelle , Breda Zélia , Guizi Alan , Costa Carlos
Published: June 2020

This paper aims at examining how overtourism and tourismphobia are being approached as emergent research topics in current tourism literature. It conducts an analysis of 154 documents, indexed in the Web of Science (WoS) Core Collection and Scopus databases. The study follows a quantitative and qualitative approach, with the support of VOSviewer and HistCite softwares for a descriptive content analysis. The analysis focuses on highlighting important aspects in terms of the most frequent publication sources (authors and journals); co-citation, as well as dimensions and research streams; methodologies used; results obtained; and implications for future research. The literature review unveiled that the concepts of overtourism and tourismphobia are usually related to destinations’ development, negative
impacts, and tourism policies and regulation. Results show that, although
tourism excesses and conflicts have been studied for long, ‘overtourism’ and
‘tourismphobia’ have become usual terms, mainly within the past three years.
Even though the adoption of the terms can be considered by some as a ‘trend’, the
in-depth analysis of the topics shed light on how ‘old’ concepts can evolve to
adapt to contemporary tourism issues. Further studies are needed in tracking the
evolution of these topics and their implications on the future of tourism.
USE OF BIM WITH PHOTOGRAMMETRY SUPPORT IN SMALL CONSTRUCTION PROJECTS. CASE STUDY FOR COMMERCIAL FRANCHISES
Authors: Loredo Conde Antonio J. , García-Sanz-Calcedo Justo , Reyes Rodríguez Antonio M.
Published: June 2020

Building Information Modelling for small constructions is a useful working tool aimed
at providing alternative solutions in building engineering. However, it is not commonly applied to this purpose,
and even less together with photogrammetry techniques. This work seeks to analyse the advantages of this methodology
with photogrammetry support in small projects. To this end, 121 commercial franchise projects in the field of
perfume and cosmetic industry were studied in order to assess the benefits of BIM methodology. These projects were
developed between 2011 and 2016. BIM protocols were shown to achieve 20% reduction in costs per project and
in working periods (4.11 days), which led to a productivity improvement exceeding 27%. The total period until
opening to public was observed to decrease in 10.09 days, and the number of inquiries and doubts during the project
execution phase handled by the construction companies were seen to reduce by 25%. Moreover, the return of investment
(ROI) corresponding to the implementation of BIM protocols was found to be more favourable than that of CAD (41.88%),
with associated internal rate of return (IRR) of 34.5%. The validity of the results is limited to the scope of works
for small commercial premises.
A MODEL TO REDUCE EARTHMOVING IMPACTS
Authors: Jassim Hassanean S.H. , Krantz Jan , Lu Weizhuo , Olofsson Thomas
Published: June 2020

Meeting increasingly ambitious carbon regulations in the construction industry is particularly
challenging for earthmoving operations due to the extensive use of heavy-duty diesel equipment. Better planning of
operations and balancing of competing demands linked to environmental concerns, costs, and duration is needed.
However, existing approaches (theoretical and practical) rarely address all of these demands simultaneously,
and are often limited to parts of the process, such as earth allocation methods or equipment allocation methods
based on practitioners’ past experience or goals. Thus, this study proposes a method that can integrate multiple
planning techniques to maximize mitigation of project impacts cost-effectively, including the noted approaches
together with others developed to facilitate effective decision-making. The model is adapted for planners and
contractors to optimize mass flows and allocate earthmoving equipment configurations with respect to tradeoffs
between duration, cost, CO2 emissions, and energy use. Three equipment allocation approaches are proposed and
demonstrated in a case study. A rule-based approach that allocates equipment configurations according to hauling
distances provided the best-performing approach in terms of costs, CO2 emissions, energy use and simplicity
(which facilitates practical application at construction sites). The study also indicates that trucks are major
contributors to earthmoving operations’ costs and environmental impacts.
Expansion of Hot Plasma with Kappa Distribution into Cold Plasma
Authors: Benáček Jan , Karlický Marian
Published: June 2020

The X-ray emission of coronal flare sources can be explained by considering the kappa electron distribution. Motivated by this fact, we study the problem of how hot plasma with the kappa distribution of electrons is confined in these sources. For comparison, we analyze the same problem, but with the Maxwellian distribution. We use a 3D particle-in-cell code, which is large in one direction and thus effectively only one-dimensional, but describe all electromagnetic effects. In the case with the Maxwellian distribution, and in agreement with the previous studies, we show a formation of the double layer at the hot–cold transition region that suppresses the flux of hot electrons from hot plasma into the cold one. In the case with the kappa distribution, contrary to the Maxwellian case, we found that there are several fronts with the double layers in the hot–cold transition region. It is caused by a more extended tail in the kappa case than in the Maxwellian one. The electrons from the extended tail freely escape from the hot plasma into a cold one. They form a beam that generates the return current and also Langmuir turbulence, where Langmuir waves accumulated at some locations. At these locations, owing to the ponderomotive force, Langmuir waves generate density depressions, where the double layers with the thermal fronts that suppress the hot electron flux, are formed. We also show how protons accelerate in these processes. Finally, we compare the Kappa and Maxwellian cases and discuss how these processes could be observed.
Fluid Theory of Coherent Magnetic Vortices in High-β Space Plasmas
Authors: Jovanović Dušan , Alexandrova Olga , Maksimović Milan , Belić Milivoj
Published: June 2020

In situ observations in Earth’s and Saturn’s magnetosheaths and in the solar wind reveal the presence of Alfvén vortices as intermittent structures in the range of scales from fluid lengths down to a few ion lengths. The density and the magnetic field associated with them appear to be compressible for higher plasma betas. Until now, only incompressible Alfvén vortices have been known. Motivated by space plasma observations, we develop a new model of magnetic vortices in high-beta plasmas with anisotropic temperature, possessing compressible density and magnetic field, whose typical size ranges from fluid to ion scales. At magnetofluid scales, we find novel nonpropagating field-aligned cylindrical monopoles and inclined propagating dipoles. Their transverse magnetic and velocity fluctuations are aligned, but not identical, and they exhibit density and compressible magnetic field fluctuations δn and

localized inside the vortex core. In the presence of thermal anisotropy and acoustic effects, they may be correlated or anticorrelated,

fluctuations whose velocity along the magnetic field is below the ion thermal speed are always correlated. At ion or kinetic scales (with the smallest radii

) and in the absence of acoustic perturbations, only dipolar Alfvén vortices survive with properties similar to those at fluid scales, except that δn/n
0 reaches the level of

. We also find pressure-balanced kinetic slow magnetosonic dipoles, possessing finite

and purely compressional magnetic field perturbation, whose existence is facilitated by a strong ion temperature anisotropy.

Published: June 2020

The energy spectrum of solar wind strahl, halo, and superhalo electrons likely carries crucial information on their possible origin and acceleration at the Sun. Here we statistically investigate the energy spectrum of solar wind strahl/halo electrons at ∼0.1–1.5 keV and superhalo electrons at ∼20–200 keV measured by Wind/3D Plasma and Energetic Particle during quiet times from 1998 to 2014, according to the types of their Potential Field Source Surface–mapped coronal source regions (CSRs). We adopt the classification scheme developed by Zhao et al. to categorize the CSRs into four types: active region (AR), quiet Sun (QS), coronal hole (CH), and helmet-streamer associated region (HS). We find that for the quiet-time strahl, the AR and HS (QS and CH) correspond to a smaller (larger) kappa index κ
strahl with the most frequent value of 7–8.5 (8.5–10) and a larger (smaller) n
strahl with the most frequent value of 0.013–0.026 cm−3 (0.006–0.0013 cm−3). For the quiet-time halo, κ
halo behaves similarly to κ
strahl, but n
halo appears similar among the four CSR types. For the superhalo, the AR (QS) corresponds to a larger (smaller) power-law index β with the most frequent value of 2.2–2.4 (1.8–2.0), while the HS and CH have a β not different from either the AR or QS; n
sup appears similar, with the most frequent value of 3 × 10−8–3 × 10−7 cm−3, among the four CSR types. These results suggest that the strahl (superhalo) from the hotter CSRs tends to be more (less) efficiently accelerated.

BACKGROUND: Water, as a natural resource, is the most basic substance of life that has immeasurable significance for the living world, ecosystems, and planet Earth. It is consumed by plants, animals, and humans.
AIM: We aimed to preform a trend analysis of total affected quantities of water and total discharged wastewater (TDWW) of Nišava district (Serbia).
METHODS: In this paper, a trend analysis is given of total affected quantities of water, delivered quantities of drinking water (DQDW), total discharged wastewater (TDWW), wastewater discharges to wastewater systems, and number of households connected to the water supply network of Nišava district (Serbia).
RESULTS: The values for Nišava district (Serbia) for total affected quantities of water and DQDW for the period 2006–2018 and wastewater discharges to wastewater systems for the period 2009–2018 decreased, whereas the values for Nišava district (Serbia) for TDWW for the period 2006–2018 and number of households connected to the water supply network for the period 2007–2018 increased. The paper also provides regression models for approximation DQDW (eq. 1) and TDWW (eq. 2) for Nišava district (Serbia) for the period 2006–2018.
CONCLUSION: Values for total affected quantities of water (×103 m³) for Nišava district (Serbia) for the period 2006–2018, they decreased from 41740 in 2006 to 9931 in 2018.
Création de nouvelles prairies dans le réseau écologique « La Frontière » VD et effets sur les orthoptères (Insecta: Orthoptera)
Authors: Breitenmoser Stève , Humbert Jean-Yves , Viollier Sylvie
Published: June 2020

Le réseau écologique Paysage « La Frontière » situé à l’ouest du canton de Vaud est composé de près de 700 surfaces de promotion de la biodiversité (SPB) totalisant plus de 500 ha. Dans ce cadre, plus de 150 ha de nouvelles prairies naturelles, pour la plupart plantées de haies et d’arbres, forment la pièce centrale de l’infrastructure écologique de ce réseau. Elles remplacent des grandes cultures (terres assolées) et ont été mises en place par la méthode de l’enherbement direct (fleurs de foin). Les orthoptères et la mante religieuse (Mantis religiosa) ont été choisis comme bio-indicateurs pour évaluer la richesse spécifique et la vitesse de colonisation de ces nouvelles surfaces. Les relevés orthoptériques ont été effectués, entre 2014 et 2018, sur 33 nouvelles prairies et ont été comparés à 13 prairies naturelles anciennes extensives. En moyenne, le nombre d’espèces par prairie était de 9.3 (dont 1.7 sur la Liste rouge) dans les nouvelles prairies et de 11.5 (2.6) dans les prairies anciennes. Statistiquement, il n’y a aucune différence significative entre les deux types de prairies. Aucune corrélation entre le nombre d’années après la mise en place des nouvelles prairies et le nombre d’espèces recensées par prairie n’a été détectée, indiquant une colonisation rapide des nouvelles prairies. Parmi les espèces d’orthoptères cibles du réseau écologique cantonal, figurant également sur la Liste rouge, six sont présentes dans les prairies anciennes comme dans les nouvelles. Parmi ces dernières,Metrioptera bicoloretEuchorthippus declivusétaient présentes dans près de 60% des prairies. Les résultats montrent l’importance d’une répartition dense de prairies à la fois de bonne qualité (enherbement direct) et exploitée extensivement avec des zones refuges. Ils soulignent également l’importance des prairies anciennes et des aires naturelles protégées comme réservoirs pour la restauration de la biodiversité dans les paysages agricoles.

Mycological investigation of various foods (mainly cowpea, groundnut, maize, rice, sorghum) and agricultural soils from two states in north-central Nigeria (Nasarawa and Niger), was conducted in order to understand the role of filamentous fungi in food contamination and public health. A total of 839 fungal isolates were recovered from 84% of the 250 food and all 30 soil samples. Preliminary identifications were made, based on macro- and micromorphological characters. Representative strains (n = 121) were studied in detail using morphology and DNA sequencing, involving genera/species-specific markers, while extrolite profiles using LC-MS/MS were obtained for a selection of strains. The representative strains grouped in seven genera (Aspergillus,Fusarium,Macrophomina,Meyerozyma,Neocosmospora,NeotestudinaandPhoma). Amongst the 21 species that were isolated during this study was one novel species belonging to theFusarium fujikuroispecies complex,F. madaensesp. nov., obtained from groundnut and sorghum in Nasarawa state. The examined strains produced diverse extrolites, including several uncommon compounds: averantinmethylether inA. aflatoxiformans; aspergillimide inA. flavus; heptelidic acid inA. austwickii; desoxypaxillin, kotanin A and paspalitrems (A and B) inA. aflatoxiformans,A. austwickiiandA. cerealis; aurasperon C, dimethylsulochrin, fellutanine A, methylorsellinic acid, nigragillin and pyrophen inA. brunneoviolaceus; cyclosporins (A, B, C and H) inA. niger; methylorsellinic acid, pyrophen and secalonic acid inA. piperis; aspulvinone E, fonsecin, kojic acid, kotanin A, malformin C, pyranonigrin and pyrophen inA. vadensis; and all compounds inF. madaensesp. nov.,Meyerozyma,NeocosmosporaandNeotestudina. This study provides snapshot data for prediction of food contamination and fungal biodiversity exploitation.

Research Data Management - Current status and future challenges for German non-university research institutions
Authors: Petersen Mareike , Pramann Bianca , Toepfer Ralf , Neumann Janna , Enke Harry , Hoffmann Jana , Mauer Reiner
Published: June 2020

This report describes the results of a workshop on research data management (RDM) that took place in June 2019. More than 50 experts from 46 different non-university institutes covering all Leibniz Sections participated. The aim of the workshop was the intra- and transdisciplinary exchange among RDM experts of different institutions and sections within the Leibniz Association on current questions and challenges but also on experiences and activities with respect to RDM. The event was structured in inspiring talks, a World Café to discuss ideas and solutions related to RDM and an exchange of experts following their affiliation to the different Leibniz sections. The workshop revealed that most institutions, independent of scientific fields, face similar overarching problems with respect to RDM, e.g. missing incentives and no awareness of the benefits that would arise from a proper RDM and data sharing. The event also endorsed that the Research Data Working Group of the Leibniz Association (AK Forschungsdaten) is a place for the exchange of all topics around RDM and enables discussions on how to refine RDM at all institutions and in all scientific fields.
Mers et océans : des espaces convoités
Authors: Hebrard Patrick
Published: June 2020

Le monde se tourne de plus en plus vers l’océan. La convention de Montego Bay a jeté les bases d’un droit de la mer qui a permis de régler des différends entre les pays et de protéger le milieu marin. Mais les espaces maritimes restent des enjeux stratégiques et la lutte pour une appro­priation des ressources, entre Chine et États-Unis, en particulier, pourrait fragiliser cette convention. Une gouvernance de la haute mer, bien commun de l’humanité, est désormais nécessaire et la France, responsable d’un large domaine maritime, doit œuvrer pour l’obtenir.
La mer comme bien commun

L’évolution du contexte stratégique est marquée par un investissement puissant de nouveaux espaces, notamment l’espace exo atmos­phérique et l’espace numérique dont les caractéristiques principales compor­tent des analogies avec les espaces maritimes. Espace, Cyberespace et milieu maritime connaissent tous trois des évolutions rapides sur le plan de la technologie, du droit et de la militarisation qui sont en train de rebattre les cartes de l’ordre mondial bâti après la seconde guerre mondiale. Marqué par le retour des « puissances » mais aussi par l’irruption d’acteurs civils de premier plan qui, eux aussi, participent à la modification des règles du jeu.

Maîtriser l’air, maîtriser l’espace : comme un bégaiement de l’histoire
Authors: Steininger Philippe
Published: June 2020

Continuum dépourvu de frontières offrant la possibilité d’y conduire des actions discrètes, voire clandestines, lieux de transit de flux de personnes, de marchandises et de données immatérielles, les espaces aérien et extra-atmosphérique font partie, avec les espaces maritime et cybernétique, de ce qu’il est convenu d’appeler les espaces communs. Si la nécessité de maîtriser l’air ne fait aujourd’hui plus débat alors que de nouveaux défis sont à relever, la maîtrise de l’espace semble bien être une idée encore dans les limbes. Or, plus que jamais, ne pas maîtriser l’espace, c’est risquer une déroute en cas de conflit. Une meilleure maîtrise du milieu spatial se matérialise au travers de la déclinaison de cinq verbes : savoir, résister, agir, communiquer et promouvoir.

El Palau Güell de Antoni Gaudí está catalogado por la UNESCO como World Heritage. Es comúnmente afirmado por arquitectos e historiadores que la superficie del diseño de la cúpula que cubre el Salón Central del Palau Güell es un paraboloide. Mediante técnicas fotogramétricas y geométricas mostramos que tal afirmación no es cierta. Esta investigación determina cual es la superficie cuádrica que mejor ajusta a la cúpula. Además, damos una medida de ese ajuste, y mostramos cuáles son los parámetros geométricos que configuran esa superficie.

The continuing emergence of viral pathogens and their rapid spread into heavily populated areas around the world underscore the urgency for development of highly effective vaccines to generate protective antiviral Ab responses. Many established and newly emerging viral pathogens, including HIV and Ebola viruses, are most prevalent in regions of the world in which Mycobacterium tuberculosis infection remains endemic and vaccination at birth with M. bovis bacille Calmette–Guérin (BCG) is widely used. We have investigated the potential for using CD4+ T cells arising in response to BCG as a source of help for driving Ab responses against viral vaccines. To test this approach, we designed vaccines comprised of protein immunogens fused to an immunodominant CD4+ T cell epitope of the secreted Ag 85B protein of BCG. Proof-of-concept experiments showed that the presence of BCG-specific Th cells in previously BCG-vaccinated mice had a dose-sparing effect for subsequent vaccination with fusion proteins containing the Ag 85B epitope and consistently induced isotype switching to the IgG2c subclass. Studies using an Ebola virus glycoprotein fused to the Ag 85B epitope showed that prior BCG vaccination promoted high-affinity IgG1 responses that neutralized viral infection. The design of fusion protein vaccines with the ability to recruit BCG-specific CD4+ Th cells may be a useful and broadly applicable approach to generating improved vaccines against a range of established and newly emergent viral pathogens.

The objective of this study is to compare the carbon dioxide (CO2) emissions from materials used in the execution of internal building masonry for construction projects that use plaster blocks and those using ceramic bricks. A total of 20 projects in the city of Recife, Brazil, were analyzed, all of them belonging to a large construction company operating in the Northeast region. The Greenhouse Gas (GHG) emissions were estimated using indexes found in the literature and calculated based on the Energy Life Cycle Assessment (ELCA). The emissions from the transport of materials to the construction site were calculated based on the driving distances between the suppliers and the building sites, taking into account the fuel consumption of the transport vehicles. The construction sites using plaster blocks for the internal masonry seals obtained an average indicator of 19.21 kgCO2/m² of constructed area compared to 33.86 kgCO2/m² from those using ceramic bricks. Construction sites using plaster blocks for internal masonry had a 43.26% reduction in GHG emissions and there was a strong correlation between costs due to the execution of activities and material emissions.

Published: June 2020

Background: Studies have reported relationship between chronic  Helicobacter pylori infection and coronary artery disease (CAD). The  cytotoxin-associated gene A product (CagA) is an immunodominant protein which indicates infection with virulent H. pylori strains. Significant  associations of CagA-positive H. pylori strains with coronary artery disorders have been widely reported. H. pylori is also known to produce different heat shock proteins (HSPs) which can stimulate the production of specific  antibody against microbial proteins and capable of eliciting autoimmune reaction against human tissue expressing HSPs such as vascular  endothelial cells. The objectives of this study are to investigate the  association between H. pylori and CagA with coronary atherosclerosis and CAD, and to determine the possible role of H. pylori HSP60 protein in increasing the risk of CAD development. Methods: This study included 70 patients with stable angina and 70 age and gender-matched controls. Each group was evaluated by clinical history, physical examination, cardiac echocardiography (ECHO) and electrocardiography (ECG) with and without exercise. Fasting blood glucose, total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL) and triglycerides (TG) were estimated by automated enzymatic methods. H. pylori IgG, CagA IgG and HSP60 IgG were measured by enzyme-linked immunosorbent assay (ELISA) for both groups. Results: The seroprevalence of H. pylori infection was high in both groups; 75.7% in case and 68.6% in control (p=0.346). Serum IgG levels were significantly higher for CagA (p=0.028) and HSP60 (p<0.001) in cases than in controls. There was significant association between H. pylori and CagA IgGs in cases (p=0.007) but no association in controls (p=0.700). Higher HSP60 IgG level was significantly associated with both positive H. pylori IgG (p<0.001) and CagA IgG (p<0.001) in cases but no significant association was found with H. pylori (p=0.815) or CagA (p=0.332) IgG levels in the control group. Serum values were significantly higher for TC (p<0.001), TG (p<0.001) and LDL (p=0.004) while value for HDL was significantly lower (p<0.001) in H. pylori IgG-positive subjects (case and control). Conclusion: There is serological evidence that H. pylori infection may pose a significant risk factor for CAD. Since H. pylori can be eliminated by specific treatment, this may be a good preventive approach for CAD.Key words: H. pylori, coronary artery disease, CagA, HSP60, serology.

Published: June 2020

Background: Mastitis caused by Staphylococcus aureus was initially considered the major problem in dairy herds, but over the last few decades, the incidence of coliform mastitis has increased among the pastoral herds in Nigeria due to poor environmental and milking hygiene. Hence, this study was aimed at genotypic identification of coliform bacteria isolated from cases of bovine mastitis among pastoral herds in parts of Kaduna State, Nigeria.Methods: A cross-sectional survey of 30 herds of cows across 7 Local Government Areas of Kaduna State, Nigeria, was conducted. One hundred and forty seven cows were proportionately selected by purposive sampling technique. The milk samples were aseptically collected and bacteriologically screened for coliform bacteria following standard bacteriological techniques. Nine out of 12 coliforms identified phenotypically were selected for PCR amplification and sequencing of their 16S rRNA gene. The Basic Local Alignment Search Tool (BLAST) analysis of the sequences obtained was done on the National Centre for Biotechnology Information (NCBI) data base, and isolates confirmed based on similarity to 16S rDNA sequences in the Gen BankResults: Five of the 9 coliforms were confirmed to be Klebsiella pneumoniae (prevalence rate, 3.4%) and 4 were confirmed to be Escherichia coli (prevalence rate, 2.7%).Conclusion: This study shows that raw milk of mastitic cows can serve as a vehicle for the spread of pathogens such as K. pneumoniae and E. coli which, according to the Department of Health and Human Services of the United States Public Health Services, are potential threats to public health and safety of humans, animals and plant products.Keywords: pastoral herds, subclinical mastitis, cows, PCR, 16s rRNA, sequencing

Background: Infection of burn wounds by multidrug-resistant (MDR) Pseudomonas aeruginosa (P. aeruginosa) is a leading cause of morbidity and mortality and remains one of the most challenging concerns for the burns unit. The aim of this study is purify and characterize the haemolysin produced by multidrug resistant P. aeruginosa PAO1 isolated from burn wounds. Methods: Isolation and identification of P. aeruginosa from burns was done by standard bacteriological methods. P. aeruginosa PAO1 was identified by PCR amplification and sequencing of the 16S rRNA gene. The haemolysin of P. aeruginosa PAO1 was purified by 70% ammonium sulphate precipitation followed by gel filtration on Sephadex G-100, and separation by SDS-Poly Acrylamide Gel Electrophoresis. In vivo toxicity of the purified haemolysin was determined by intraperitoneal injection of Swiss albino mice, and in vitro toxin-antitoxin neutralization test was performed as previously described. Results: The pure haemolysin had a molecular weight of 37 kDa, with maximum activity at 25°C for 30 minutes and stable within pH range of 4-9 (maximum activity at pH 7). The haemolysin was activated by Ca2+, Fe3+ and Cu2+. Intraperitoneal injection of mice with 0.5ml of haemolysin (128 HU/ml) caused 100% mortality while 0.5 and 0.1 ml of haemolytic titer (64 HU/ml) of the heated haemolysin (toxoid) caused 50% and 0% mortality respectively. In vitro toxin-antitoxin neutralization test revealed that anti-haemolysin antitoxin was present in the serum of the mice that were previously vaccinated with heated toxin. Conclusion: This study concluded that haemolysin can be a potential vaccine component for prevention of haemolysis caused by multidrug resistant P. aeruginosa in burn patients.Keywords: haemolysin, Pseudomonas aeruginosa, multidrug resistant organism
