Valorisation de résidus agricoles et autres déchets organiques par digestion anaérobie en Haïti
Authors:   ,   Université Quisqueya, Lacour Joaneson
Published: December 2021

Dans les espaces ruraux et périurbains d’Haïti, les déchets et résidus organiques générés principalement par les activités agricoles et agroindustrielles, sont traditionnellement valorisés in situ dans l’alimentation animale comme provende, dans la fertilisation des sols comme amendement organique et/ou à des fins énergétiques comme combustibles. Parallèlement, au niveau des villes, les déchets organiques sont majoritairement éliminés sans aucune forme de ségrégation dans des décharges non contrôlées. Ce travail de recherche a voulu mettre l’accent sur l’opportunité de valoriser ces déchets par la méthanisation approchée comme une voie alternative de traitement biologique des déchets organiques fermentescibles. Le travail d’évaluation des gisements de déchets organiques a mis en évidence que la mauvaise gestion de ces gisements entraine une perte annuelle de « déchets-ressource » estimée à près de 2 960 000 tonnes de matière sèche, potentiellement convertibles en 367 500 000 Nm3 de méthane ou 310 000 tep, correspondant à environ 16% de la couverture énergétique finale des ménages à l’échelle nationale. L’approche expérimentale à l’échelle de laboratoire a permis d’évaluer les potentiels biométhanogènes de certaines catégories de déchets d’origine agricole, dont la bagasse, le chou et les déjections de bovins, porcins et poulets, ainsi que les possibilités d’optimisation des cinétiques de digestion anaérobie par des moyens peu onéreux comme la réduction de la taille des particules, l’augmentation du ratio InoculumMV/SubstratMV et les effets de synergie liés à la co-digestion. Des recherches à l'échelle du pilote de terrain ont également été réalisées. Un digesteur a été construit sur le modèle des digesteurs indiens et suivi pendant plusieurs semaines. Malgré les conditions particulières de mise en œuvre du pilote, les essais réalisés ont démontré la faisabilité de la filière avec la technologie rustique sélectionnée. Le temps de retour sur investissement pour un fonctionnement optimal du digesteur pilote a été estimé à 5 ans.
Conditions pour la mise en place durable d’une filière d’assainissement par toilettes sèches à litière bio-maîtrisée dans les zones rurales des pays en développement. Application au contexte haïtien

Published: December 2021

Ce travail vise à proposer une solution d’assainissement durable, digne, sécurisante, accessible à tous, permettant de réduire les maladies à transmission hydrique, adaptée aux populations vivant dans des conditions précaires en zones rurales de pays en développement. Il contribue ainsi à la lutte contre la défécation à l’air libre, une des cibles de l’Objectif de Développement Durable n°6 concernant l’eau et l’assainissement. Le choix s’est porté sur des toilettes sèches individuelles à litière biomaîtrisée et un mode de gestion communautaire des résidus, en lien avec une association paysanne locale. La mise en place s’est faite avec un accompagnement scientifique qui a donné lieu aux travaux présentés ici. Dans un premier temps, nous avons opéré selon une approche participative, visant à s’assurer de l’adhésion des utilisateurs. Puis nous avons mené un programme scientifique pour identifier les conditions permettant l’hygiénisation des résidus traités. Après 3 ans d’expérimentation, la filière d’assainissement mise en place est totalement adoptée par les ménages, qui apportent régulièrement leurs résidus sur le site de compostage. Une enquête a fait ressortir que les familles sont très satisfaites de ce mode d’assainissement à domicile et se sentent moins sujettes à des maladies féco-orales. Ces ménages se sont constitués en un groupe qui procède à présent à l’appui à la réplication. Les litières absorbantes utilisées, les résidus avant et après traitement par compostage ont été caractérisés. Des essais en pilotes ont permis de déterminer les conditions permettant de garantir une hygiénisation rapide, ce qui était un de nos principaux objectifs, afin de réduire les risques sanitaires. Nous sommes à présent à même de définir les « bonnes pratiques » pour que la filière d’assainissement par toilettes sèches à litière biomaîtrisée dans une zone rurale de pays en développement soit sûre et durable, sur les aspects sociaux, techniques, économiques, environnementaux et sanitaires.
Impacts des eaux pluviales urbaines sur les eaux souterraines dans les pays en développement – mécanismes de transfert des métaux lourds à travers un sol modèle de Port-au-Prince, Haïti
Authors:   ,   Université Quisqueya, Fifi Urbain
Published: December 2021

L’infiltration directe des eaux pluviales urbaines dans les formations superficielles des pays en développement constitue un risque de contamination à la fois pour ces formations et/ou pour les eaux souterraines sous?jacentes. Cette thèse s’est focalisée sur cette problématique environnementale dans laquelle nous avons étudié le transfert réactif de trois métaux lourds (Pb, Cu et Cd) dans une formation géologique représentative : alluvions fluviatiles de la plaine du Cul?de?sac à Port?au?Prince (Haïti). Un « sol modèle » provenant du site d’étude, fraction granulométrique ≤ 2 mm considérée comme la plus réactive, a été utilisé et soumis à des solutions chargées en ions métalliques suivant deux conditions expérimentales distinctes : essais en conditions statiques (batch) et en conditions dynamiques (colonne). Les résultats obtenus à partir de ces dispositifs expérimentaux ont mis en évidence les mécanismes de rétention ou de relargage des ions métalliques dans les formations géologiques de Port?au?Prince. Les résultats en batch ont montré que la compétition entre deux ou plusieurs cations pour les mêmes sites actifs du sol peut inhiber leur sorption individuellement. Les résultats en colonne ont prouvé le caractère réactif du sol vis?à?vis des trois métaux, dont environ 99, 94 et 92 % respectivement de cadmium, de plomb et de cuivre ont été retenus dans la matrice solide. L’étude des interactions entre les métaux et l’échantillon de sol à l’aide du code PHREEQC ont montré qu’une partie des métaux a été précipitée sous la forme de carbonates (cérusite et otavite) et d’hydroxydes, et que le comportement physico?chimique des trois métaux dans le sol a été également influencé par l’échange ionique. Toutefois, les métaux retenus sont susceptibles d’être relargués et remobilisés sous l’effet d’un changement brusque des conditions acido?basiques du milieu poreux, représentant ainsi un risque de pollution pour les eaux souterraines.

L’objectif de ce travail est la valorisation de sous-produits agricoles ou d’autres déchets issus de la biomasse végétale de la Caraïbe par la production de charbon actif (CA) en vue du traitement de l’eau. La biomasse utilisée dans ce travail est constituée de racines de vétiver (RV) (Vetiveria zizanioides), de bagasse de canne à sucre (Saccharum officinarum L) et d’une macro algue marine (Turbinaria turbinata). Ces matériaux ont été caractérisés. Les RV sont plus riches en lignine (33%). Par contre la bagasse est plus riche en cellulose (50.6%). Alors que, la turbinaria contient beaucoup plus de cendres (16%). Des CAs ont été produits par activation physique à la vapeur d’eau avec des rendements de 13% (RV), 11% (bagasse) et 21% (turbinaria), puis par activation chimique avec l’H3PO4 dont les rendements sont de 48% (RV), 47% (bagasse) et 49% (turbinaria).
Éléments pour une définition de la problématique de la propreté urbaine en Haïti : le cas de Port-au-Prince
Authors:   ,   Université Quisqueya, Bras Anie
Published: December 2021

La gestion des déchets ménagers figure parmi les préoccupations les plus complexes auxquelles doivent répondre les gestionnaires urbains, en particulier dans les villes des pays en développement. A Port-au-Prince, capitale de la République d’Haïti, l’historique de la gestion des déchets ménagers met en lumière un décalage entre l’objectif du service (rendre et maintenir la ville propre) et les réalités du terrain. La question relative aux causes explicatives possibles à ce hiatus, constitue l’ossature de ce travail de thèse, dont l’objectif général consiste à cerner la problématique du service de propreté dans la ville de Port-au-Prince. La démarche méthodologique élaborée, dans le cadre de cette recherche, est axée sur deux campagnes d’observation directe et indirecte des pratiques des ménages vis-à-vis de leurs déchets et du fonctionnement du service, alliés à des entretiens avec les principaux gestionnaires responsables du service et des usagers. La constitution du corpus s’inscrit donc dans une dimension très large, englobant les données relatives au jeu des acteurs, à l’organisation, aux pratiques des usagers vis-à-vis de leurs déchets et le fonctionnement du service. L’exploitation et l’analyse de ces données ont permis d’élucider le modèle de gestion des déchets jusqu’ici privilégié dans le milieu haïtien, qui est assimilable aux transferts technologique et organisationnel Nord-Sud, généralement adopté par les PED. De par son incapacité à prendre en compte les aspérités socio-économique et urbanistique propres au contexte local, ce modèle a montré ses limites, ce qui a conduit à l’émergence d’autres acteurs, comme les entreprises privées, les ONG, les comités de quartiers, les Associations socioprofessionnelles et des usagers pour pallier le déficit de service en matière de gestion des déchets ménagers à Port-au-Prince. Cependant, l’émergence de cette multiplicité d’acteurs ne permet pas d’améliorer le taux d’enlèvement des ordures en particulier dans la catégorie d’habitats bas standing. La recherche a permis de déterminer la production de déchets ménagers par habitant par jour par zone d’habitats observée, dont la moyenne a atteint respectivement 0,80 ; 0,75 et 0,5 kg/hab./jr pour les trois zones d’habitats, haut, moyen et bas standing de la ville de Port-au-Prince. Les résultats concernant les pratiques des usagers vis-à-vis de leurs déchets montrent que les comportements des ménages varient sensiblement d’une zone d’habitats à une autre, et sont fortement tributaires du fonctionnement du service, et dans une moindre mesure des croyances religieuses. Cependant, la ravine reste l’exutoire des déchets ménagers fortement privilégié par les usagers, en particulier dans les zones d’habitats bas standing où 87,4% des personnes interrogées admettent avoir utilisé une ravine pour déverser leurs déchets, contre 53 et 23% pour les zones d’habitats haut et moyen standing.

Orchid seeds are very small, dust like in appearance, fusiform in shape, lacking endosperm and have undifferentiated embryo covered by transparent seed coat. Mycorrhizal association is required for seed germination of naturally growing orchids. In this symbiotic association, orchid species are dependent on mycorrhizal association for supply of mineral nutrients. In in-vitro condition, such demand of minerals may be compensated by external supply of sugar and mineral nutrients that are required for seed germination of orchid. Several orchids are responded by this asymbiotic seed culture and have commercial importance. Therefore, formulation of efficient in-vitro protocol is important for commercially important orchid species as well as endangered orchid species for conservation. This review paper is focused on various aspects of asymbiotic seed germination of orchids and the role of organic additives in successful seed germination.

Published: December 2021

Dental anatomy can vary significantly between different populations from different countries. Dental anatomical variations are of great interest to the dental professional, especially to endodontists, since they can influence the outcome of endodontic treatment. The purpose of the present study was to describe the anatomical variations of the root canal in mandibular first premolars in a population from Colombia, using micro-computed tomography. Fifty mandibular first premolars were scanned on a SkyScan 1174 and the microcomputed tomographic images were reconstructed. Anatomy was assessed using three-dimensional models. The parameters used were: Vertucci’s classification, area and volume, perimeter, circularity, and major and minor diameter at 1, 2 and 3 mm from the apical foramen. According to the Vertucci’s classification, teeth were classified as: types I (40%), V (24%), VII (4%) and III (4%), with 28% not classifiable. C-shaped canals were found in 1.8% of the sample. Mean evaluations at 1, 2, 3 mm of the foramen were as follows, respectively: perimeter 1.07 ± 0.57, 1.27 ± 0.78 and 1.57 ± 0.84 mm; circularity 0.59 ± 0.19, 0.57 ± 0.20 and 0.56 ± 0.22; maximum diameter 0.41 ± 0.23, 0.48 ± 0.33 and 0.60 ± 0.37 mm; minimum diameter 0.24 ± 0.10, 0.26 ± 0.11 and 0.21 ± 0.13 mm. Mean total area and volume were 61.27 ± 16.47 mm2 and 12.47 ± 4.95 mm3, respectively. There was wide anatomical variation in mandibular first premolars from Colombian individuals, reinforcing the need for proper anatomical knowledge to establish more effective strategies for endodontic treatment.

Published: December 2021

Adhesively cemented fiber-reinforced composite posts are commonly used to reconstruct endodontically treated teeth. Adhesion to intraradicular dentin is complex, and close contact between the resin cements and the dentin is essential. The removal of the smear layer following post space preparation (secondary smear layer) can improve this integration. Different mechanical systems have been used to activate the irrigant inside the root canal. The purpose of this study was to compare, ex-vivo, the removal of the smear layer from the walls of the immediate post space preparation by the action of three mechanized instruments. Forty premolar specimens with a single root canal were selected, endodontically treated, and shaped for glass fiber post cementation with Peeso reamer #1 (Dentsply Sirona, Switzerland) and Macrolock finishing drill #3 (RTD, France). The specimens were randomly divided into 4 groups (n=10): Group C (control); Group PUI (passive ultrasonic irrigation); Group CEP (Rotoprox brush, Hager Werken, Germany) and Group XP (XP-endo Finisher, FKG Dentaire, Switzerland). Post space surfaces were cleaned with 3mL of distilled water; each specimen root split longitudinally to expose the root canals, and prepared for examination in a scanning electron microscope at magnification 350X. The results were analyzed using the Kruskal-Wallis and Friedman tests (p>0.05). RESULTS: Statistically significant differences (p <0.05) were found between Groups C and XP in all three root regions, but not between Groups C, CEP and PIU. Of these, Group CEP showed a better trend in the results of the coronary and middle thirds, without significant difference with Group XP. Although it was difficult to achieve a clean dentin surface after preparation for the fiberglass post, the XP-endo Finisher was the most efficient in removing secondary smear layer, followed by the Rotoprox conical brush.

Published: December 2021

This paper reviews the development of demand response (DR) and dynamic thermal rating (DTR) system for enhancing the operation and reliability of power system. The advantages and prospect of the DR program are discussed. The case for DTR system is established by comparing it against the traditional static thermal rating (STR) system. Various line monitoring methods and devices required for the implementation of the DTR system are presented. The challenges for deploying the DTR system from the perspective of selecting appropriate transmission lines for DTR deployment, identifying critical spans for deploying DTR sensors, managing the reliability of the DTR system, and the integration of the DTR system with existing and future power systems are discussed. Finally, the two main standards governing the operation of the DTR system, namely the IEEE 738 standard and the CIGRE standard are compared to elucidate the employability of the DTR system.
Anastas Benderev's 1890 Ethnographic Maps
Authors:   Union of Scientists in Bulgaria, Yordanov Dragomir
Published: December 2021

This article deals with a pair of old ethnographic maps made by a Bulgarian officer (bearing the rank of Captain at the time) named Anastas Benderev (1859–1946). The maps were first published as folding attachments in Benderev’s book Military Geography and Statistics of Macedonia and Its Adjacent Territories on the Balkan Peninsula (Voennaia geografiia i statistika Makedonii i sosednikh s neiu oblastei Balkanskago poluostrova), which itself was published in Russian in Saint Petersburg in 1890. The stated purpose of the maps was to elucidate certain passages from the book, particularly those pertaining to the population’s ethnic composition. One of the maps (Etnograficheskaya karta Balkanskogo poluostrova) depicts the ethnicities across the entire Balkan Peninsula, while the other (Etnograficheskaya karta Makedonii) focuses on those within the confines of the historical and geographical territory of Macedonia. Due to a confluence of events, the maps in question are barely known and hardly ever used nowadays, even though they represent valuable relics from the era. This article aims to reintroduce them into the scientific discourse as historical documents of note.

Demographic and Religious Changes in Nahiya Kara Lom in the 17th–18th Centuries
Authors:   ", Nedelcheva Nevena ,   St. Cyril and Methodius",   University of Veliko Tarnovo
Published: December 2021

The report presents the changes that took place in nahiya Kara Lom between the late 17th and early 18th centuries. It is based on published and unpublished Ottoman documents – detailed cizye and avariz defters, stored in the Ottoman Archives in Istanbul and at the Oriental Department in Sofia. They were composed in the late 17th – first half of the 18th centuries. At the turn of the 18th century, very significant transformations took place in this region, which changed its appearance and state fundamentally. The main focus of the study is on the demographic and religious changes and processes in the region. They were expressed in the sharp decline of the population. This process was specific to the whole region, and its causes can be traced to many factors that have had a detrimental effect. These included climate change, plague epidemics, population migrations, economic problems in the Ottoman Empire, and the process of Islamization. They led to a decline in the population of Kara Lom, which can be described as a demographic crisis. In the vortex of this crisis, there was a “change” of the confessional image of the nahiya, i.e. a radical change in the religious model of the district, which had disastrous consequences for many settlements in the region. The report provides possible explanations for the demographic and religious transformations in nahiya Kara Lom, which shaped the area in the next century as we know it today.
On the question of the multimodality of perceptions and its reflection in language
Authors: Petrova Anastasiya
Published: December 2021

The article focuses on the semantics of the Bulgarian lexeme глух, examined on a wider Slavic, Balkan and Indo-European background. The emphasis is on the phenomenon of verbal synaesthesia, which allows the manifestation of the cross-modal character of many image schemes that gave rise to its semantic structure. The analysis is an opportunity to verify the established models of metaphorical projections from lower to higher modalities with respect to the Bulgarian lexeme глух. The relationship between perception and conceptual structure is being studied with particular interest in contemporary linguistics, so the study of the role of non-visual experience in structuring a semantic system in a language complements the general idea of linguistic synaesthesia and its role in all languages.
Lyuben Georgiev’s innovative ideas concerning Bulgarian language teaching Radomira Videva. Easy-to-read legal texts as a means of INCREASING the cognitive accessibility of legal language
Authors:   Paisii Hilendarski University of Plovdiv, Bulgaria, Cholakov Ivan
Published: December 2021

The present paper is focused on Lyuben Georgiev’s innovative ideas concerning Bulgarian language teaching. The author’s new ideas presented in his work The Mother Tongue in Our Junior High Schools and High Schools (a Language Teaching Endeavour) (1933) have not been the subject of scientific research so far. L. Georgiev’s set of didactic ideas is important evidence for the overcoming of the Herbartian model and the orientation of language teaching towards the formation of communicative competencies. Emphasizing the creative nature of pedagogical interaction, Lyuben Georgiev offers a comprehensive system of ideas – a system that is in line with modern trends in language learning.
Population of Chernigov in the 10th–13th Centuries According to Paleodemographic Data
Authors:   National Academy of Sciences of Ukraine, Kyiv, nstitute of Archaeology RAS, Moscow, Russian Federation, Dolzhenko Yurii , Tarasova Anna
Published: December 2021

The work is devoted to the 10th–13th-century paleodemographic data regarding the city of Chernigov and its districts, and to their introduction into the scientific domain. The study is based on the data on the anthropological series of Chernigov in the 10th–13th centuries, divided into three samples according to the topographic principle. This series is characterized by a low average life expectancy in comparison to other southern Old Rus cities. The feature of the necropolises of Chernigov indicating the predominance of female burials over male ones, revealed in the 1980s, has been confirmed at a new level. A study of the demographic parameters of the Chernigov population groups in the 10th–13th centuries, united on a territorial basis, has shown differences in their structure, probably reflecting the peculiarities of the life quality, social status, and professional specialization of the population of different parts of the city. Further research into the remains of the city’s population with methods of paleopathology, osteometry, osteoscopy, radiology, etc., as well as the analysis of aspects of the political history of the region, would help shed light on the possible causes of the identified features of the demographic structure of the population in the pre-Mongolian period.

The appositional construction in Bulgarian – Issues, opinions, solutions
Authors:   ", Getsov Anton ,   St. Cyril and Methodius",   University of Veliko Tarnovo
Published: December 2021

The article discusses several solutions that aim to reveal the direction of the dependence between the components of the appositional construction. An emphasis is placed on the analysis of the most amorphous and debatable structural type: common noun + proper noun. One of these solutions concerns the choice of a basic research approach and its consistent and logically sound application, which would aid the correct “distribution” of the syntactic functions of the components in constructions of this structural type. The article draws special attention to the autonymic use of proper nouns. It is based on the premise that the two components of this type of appositional construction can have a common reference, which is a function of their different referential features and that these components contribute – to a varying degree – to the realization of these features.

Published: December 2021

This paper examines how the representatives of the Bulgarian and Polish linguocultural community understand hospitality. Focusing on the linguistic picture of the world in both languages (which entails a lingo-anthropological analysis of Bulgarian and Polish phrases, idioms, words, and sayings) we discover some similarities between the Bulgarian and the Polish worldview, linked to the theme of ‘hospitality’. The study also contains a comparative analysis of Bulgarian/Polish and English expressions. The analysis is used to outline some unique features in the fragment of the Bulgarian/Polish linguistic picture of the world we are looking at.

We discuss the important policy implications of the dynamic impact of international gold and oil price on stock market index.
Governance of Mutual Fund Industry -The Lifeline of Capital Market
Authors: Islam Mir Ariful
Published: December 2021

A mutual fund is a kind of monetary vehicle comprised of a pool of cash gathered from numerous financial backers to put resources into protections like stocks, securities, money market instruments, and different resources. In Bangladesh, the mutual fund industry keeps struggling, yet nobody at any point contemplates what the primary driver are behind this. Accordingly, the paper attempts to track down the reason behind the poor performance of the mutual fund industry in Bangladesh. The paper finds that governance of the funds is some way or another liable for poor performance of the funds, however not the principle reason. Some other elements are likewise liable for the poor performance of the mutual fund industry.

Published: December 2021

The main objective of this work was to explore the configuration of those elements that allow students to better adapt to university environments and persist even in the presence of difficulties. The sample consisted of 371 undergraduate students (60% female), of low socioeconomic level, enrolled in public universities in the Caribbean region of Colombia. The methodological approach was based on a cluster analysis, in which, using the hierarchical agglomerative method, groups were extracted according to their similar characteristics of resilience in 12 dimensions assessed by the SV-RES scale and subsequent analyses of variance reported how each style was associated with engagement, and with a particular constitution of personal support networks, assessed respectively with the UWES-S scale, and from a square matrix of reticular data on the social networks of each participant. The results showed four profiles of students, characterized by: a) low resilience, high engagement, and strong support networks; b) resilience with low engagement, and dispersed support networks; c) resilience with high autonomy, intermediate levels of engagement, and weak support networks; and d) resilience, high engagement, and strong social support networks.
Towards a Framework for Assessing Cybersecurity Risks in Internet of Things (IOT) Devices
Authors: Qiao Zhilei , Rivera Julio C. , Zhou Mi
Published: December 2021

The term Internet of Things (IoT) refers to a broad class of devices used by business entities as well as consumers to provide or consume a broad array of services. All these devices share their need to connect to the internet to deliver their native functionality. This connection requirement exposes the devices to the cybersecurity threats found on the internet. Existing literature on IoT cybersecurity solution models has shown that different technologies, such as communication technologies, mobile-app based authorization framework, graph-theoretic approach or blockchain technologies, have been majorly proposed to solve IoT security issues. However, these studies only focus on some specific IoT security issues like data theft or security issues on some specific layer across the whole IoT architecture. Therefore, there is a lack of systematic framework to solve IoT cybersecurity issues. This paper presents a framework for assessing such risks. In the qualitative analysis results, the device threats seem more severe than data confidentiality and privacy issues. This surprising finding highlights the significances of security taxonomy because both issues are based on different technical requirements. Our study has important managerial and practical implications for users, managers, and policymakers.
How Does a Cell Change Flow Direction Due to a Micro Groove?
Authors: Hashimoto Shigehiro , Matsumoto Taketo , Uehara Shogo
Published: December 2021

The change in direction of a cell flowing over an oblique micro groove has been analyzed in vitro. The micro flow-channel (0.05 mm height x 1 mm width x 25 mm length) with oblique micro grooves (4.5 μm depth) was manufactured on a polydimethylsiloxane (PDMS) disk by the micromachining technique. The angle between the main flow direction and the longitudinal axis of the groove is 45 degrees. The effect of variation of the groove width (0.03 mm, 0.04 mm, and 0.05 mm) was studied. Myoblasts (C2C12: mouse myoblast cell line) were used in the test. The main flow velocity (0.02 mm/s < vx < 0.23 mm/s) of the medium was controlled by the pressure difference between the inlet and the outlet. The shape of each flowing cell was tracked on a movie recorded by the camera attached to the eyepiece of the microscope. The experimental results show that the change of the direction of each cell by each groove depends on the shape of the cell, which depends on both the shape of the cell and the width of the groove.

The Fourth Industrial Revolution: Technology and Education
Authors: Cowin Jasmin
Published: December 2021

The convergence of data, computation, and globalization in education has far-reaching consequences for educational stakeholders, institutions, and learners. Terms such as the Fourth Industrial Revolution, artificial intelligence (AI), exponential technology, deep learning, personalized competency-based learning, and distributed ledger technology networks (DLTNs) are indicators of the changing dialogue between education stakeholders, businesses, and government aspirations on a global scale. Location-independent virtual environments promise an exponential expansion that goes beyond brick-and-mortar schools, colleges, and universities. AI and intelligent systems are poised to become global change agents in education, ushering in profound changes in administrative functions, strategic planning, data aggregation, student acquisition and retention, and alternative currencies, as well as curriculum design, assessment, personal learning networks, and global competitiveness generally of both institutions and their graduates. The quality of the education a nation's schools, educational institutions, and teachers provide, along with investments in science, technology engineering, and mathematics education, directly impact economic prosperity and global competitiveness. This paper explores some of the interdependencies that arise from supercharged technological advances such as AI augmented reality digital technologies (ARDTs) and DLTNs and their possible impact on education, educators, learners, and society. In addition, it unbundles the meaning and use cases of AI, ARDTs, and DLTNs in education.
Agile Methodology and War Strategies
Authors: Tudose Cătălin
Published: December 2021

The history of humankind offers lots of remarkable ideas and innovations in strategy and tactics. There is no area where people have shown more inventiveness than defending themselves or attacking and conquering others. On the other hand, the Agile methodology emerged from software development, where it tried to provide support for the successful organization of delivery projects, that have to fight and conquer the complexity. This article evidences similarities between the Agile methodology and attacking and war strategies, making extended references to one of the most renowned military treaties: Sun Tzu's The Art of War. Making inter-disciplinary analogies, comparing and contrasting the concepts from different disciplines are at the core of this article. We'll investigate what things as initial estimations, attack by stratagem, tactical dispositions, energy, weak points, and strong points, maneuvering, variation in tactics, the army on the march, terrain, arriving on unknown ground, concrete situations on the ground, the use of spies, or what the attack by fire may mean in software development. We'll analyze how these war strategy concepts transpose to Agile concepts like adding business value, getting to the business goals, managing complexity, conducting the work the incremental and non-incremental way.

Introduction: Procedural specialties are at higher risk for malpractice claims than non-procedural specialties. Previous studies have examined common damages and malpractice lawsuits resulting from specific procedures. Our goal was to analyze urological interventions that led to sexual dysfunction claims.
Methods: The Casetext legal research platform was queried using search terms for medical malpractice and common men’s health procedures between 1993 and 2020. In total, 236 cases were found and 21 cases met the inclusion criteria: malpractice cases against a urologist or urology group, clearly stated legal outcome, and allegation of sexual dysfunction from an intervention that directly caused damages.
Results: A total of 42 damages were cited in 21 lawsuits. The top three damages claimed were erectile dysfunction (14/42, 33.3%), genital pain syndrome (7/42, 16.7%), and urinary incontinence (5/42, 11.9%). The most commonly cited treatments were urinary catheter placement or removal (3/21, 14.3%), robotic-assisted laparoscopic radical prostatectomy (RALP) (3/21, 14.3%), circumcision (3/21, 14.3%), and penile implant (3/21, 14.3%). In 19 of 21 suits (90.4%), the outcome favored the defendant. Two cases favored the plaintiff: penile implant (failure to prove the patient was permanently, organically impotent prior to the procedure; $300 000) and vasectomy (damage to vasculature resulting in loss of testicle, $300 000).
Conclusions: Most suspected malpractice cases resulting in sexual dysfunction favored the defendant urologist. Interestingly, urinary catheter placement is as likely to result in litigation as other operative interventions, such as RALP, inflatable penile prosthesis, and circumcision. It is possible that thorough preoperative counselling and increased responsiveness to patients’ postoperative concerns may have avoided litigation in several cases.

Introduction: This was a secondary analysis aiming to assess whether hydrophilic or hydrophobic statins have a differential effect on urinary retention (UR) and lower urinary tract symptoms (LUTS) in men following a prostate biopsy (PB), who were at risk for prostate cancer development.
Methods: This was a population-based cohort study with data incorporated from the Institute for Clinical and Evaluative Sciences database to identify all Ontarian men aged 66 and above with a history of a single negative PB between 1994 and 2016, with no drug prescription history of any of several putative chemopreventative medications (statins, proton pump inhibitors, five-alpha-reductase inhibitors, and alpha-blockers). Multivariable Cox regression models with time-dependent covariates were used to assess the association of hydrophilic and hydrophobic statins with UR and LUTS within 30 days of a PB. All models were adjusted for other known putative chemopreventive medications, age, rurality, pharmacologically treated diabetes, comorbidity score, and study inclusion year.
Results: Overall, 21 512 men were included, with a median followup time of 9.4 years (interquartile range [IQR] 5.4–13.4 years). Hydrophobic and hydrophilic statins were initiated by 30.7% and 19.6% of men, respectively, after the first negative PB. UR and LUTS were experienced by 2.2% and 10% of men, respectively. Cox models demonstrated hydrophilic statins were associated with a lower risk of UR (hazard ratio [HR] 0.56, 95% confidence interval [CI] 0.38–0.83, p=0.0038) and LUTS (HR 0.86, 95% CI 0.76–0.98, p=0.022), while no such association was shown for hydrophobic statins.
Conclusions: Initiation of hydrophilic statins in men older than 66 appears to be inversely associated with the risk of UR and LUTS within 30 days of a PB.
Techniques – Mini incision and plication (MIP) cure hydrocele: A minimally invasive surgical variation
Authors: Nassour Anthony Joe , Ashrafi Darius , Patel Dinesh
Published: December 2021

Idiopathic hydroceles are the commonest cause of chronic benign scrotal swelling, affecting 1% of adult men. Larger idiopathic hydroceles can become symptomatic and affect quality of life. The popular Jaboulay technique described in 1902 is curative and remains the standard for most surgeons. However, it is associated with significant morbidity and has a reported recurrence rate of 5%. Various minimally invasive approaches have been described with fewer reported complications but are of limited efficacy and unacceptable recurrence rates requiring multiple treatments. In this single-surgeon case series of 92 men, we present the mini incision and plication (MIP) cure hydrocele technique for the treatment of idiopathic hydrocele. This minimally invasive open surgical variant achieves the desired eversion and plication with minimal hydrocele manipulation, providing excellent results independent of hydrocele size, with fewer complications and a recurrence rate of <1%.
Killing Tensor Fields of Third Rank on a Two-Dimensional Riemannian Torus
Authors: Sharafutdinov Vladimir A.
Published: December 2021

A rank m symmetric tensor field on a Riemannian manifold is called a Killing field if the symmetric part of its covariant derivative is equal to zero.

Such a field determines the first integral of the geodesic flow which is a degree m homogeneous polynomial in velocities. There exist global isothermal coordinates on a two-dimensional Riemannian torus such that the metric is of the form ds^2= λ(z)|dz|^2 in the coordinates. The torus admits a third rank Killing tensor field if and only if the function λ satisfies the equation R(∂/∂z（λ(c∆^-1λ_zz+a))= 0 with some complex constants a and c≠0. The latter equation is equivalent to some system of quadratic equations relating Fourier coefficients of the function λ. If the functions λ and λ + λ_0 satisfy the equation for a real constant λ0, 0, then there exists a non-zero Killing vector field on the torus.

Wijziging van collectieve arbeidsvoorwaarden na overgang van onderneming

Naar aanleiding van het mijlpaalarrest Rode Kruis Ziekenhuis/Te Riet uit 2003 onderzoekt de auteur welke invloed de verschillende wijzigingsmogelijkheden uit de Richtlijn Overgang van onderneming uitoefenen op de wijziging van collectieve arbeidsvoorwaarden na een overgang in het Nederlandse recht. Waar de Richtlijn namelijk voorziet in verschillende wijzigingsmogelijkheden al naar gelang het individuele of collectieve arbeidsvoorwaarden betreft, heeft Rode Kruis Ziekenhuis/Te Riet dit onderscheid in het Nederlandse recht doen vervagen.

De permanente tijdelijkheid. Over arbeidsovereenkomsten voor bepaalde tijd en EU-recht

In deze bijdrage staan de Richtlijn 1999/70/EG en de raamovereenkomst tijdelijke arbeidsovereenkomst centraal. In het bijzonder wordt stilgestaan bij de vraag of de zogenoemde ‘objectieve redenen’-toets van het Hof van Justitie van de EU, waarin het ‘doel van de raamovereenkomst’ een prominente rol speelt, effect sorteert voor andere antimisbruikgronden, zoals maximering van aantal en duur van tijdelijke contracten. De auteur bepleit dat onder omstandigheden het repeterend flex voor flex contracteren in strijd is met (het nuttig effect van) de Richtlijn en bijgevolg niet is toegestaan.
Rechtstreekse horizontale werking van het EU Handvest in getrapte vorm

Rechtstreekse horizontale werking van het EU Handvest in getrapte vorm

In 2018 en 2019 kwam het Hof van Justitie van de EU met een aantal zaken waarin het Hof rechtstreekse horizontale werking toekent aan grondrechten in het EU Handvest. Een van die arresten betreft de gevoegde zaken Bauer en Willmeroth, waarin artikel 31 lid 2 van het Handvest rechtstreekse horizontale werking toegekend krijgt. Uit het iets later gewezen arrest over de gevoegde zaken TSN en AKT valt echter op te maken dat die rechtstreekse werking wellicht niet zo rechtstreeks is als het Hof doet voorkomen.
