O turismo olivícola na Provença, uma forma de turismo inacabada
Authors: Bachimon Philippe , Dérioz Pierre
Published: July 2024

A oliveira, árvore emblemática e emblemática, faz parte da oferta turística genérica da Provença e dos seus arredores. Foi desenvolvida por indivíduos e/ou grupos, por vezes com o apoio das colectividades locais, mas o panorama é tão variado que não existe um produto local único e consensual, como acontece com a vinha e a alfazema. É frequente existir um claro desfasamento entre a função simbólica da oliveira e a sua presença efectiva na paisagem. Os intervenientes no sector estão dispersos, raramente federados em torno de uma DOC (com exceção de Les Mées, Nyons e Les Alpilles), para não dizer altamente individualizados. Pelo contrário, estão envolvidos em múltiplas actividades, nas quais a azeitona é frequentemente secundária e, por vezes, até um passatempo para os habitantes das cidades ou dos subúrbios. É certo que, desde meados dos anos 90, a dimensão turística do produto se acentuou, com a venda direta de azeite, de subprodutos e de produtos conexos, bem como de serviços associados (restauração, visitas aos locais de produção, sinalização dos itinerários olivícolas, definição de paisagens artefactuais, etc.). A Provença, grande destino turístico, é tentada a promover a sua produção "fora do comum" (reduzida em dimensão e em rendimento, aos preços mais elevados do mercado). Mas há grandes discrepâncias entre o discurso auto-preditivo (profissional, político, etc.) e a realidade no terreno.
Wine & Olive Oil food heritage synergies within the tourism experience: Analyzing corporate websites
Authors: Salvado Josefina , Monteiro Bebiana
Published: July 2024

Portugal is amongst the largest producers of wine and olive oil in the world. This paper aims to understand how wine tourism (Enotourism in future references) farms in the Douro region are able to enhance synergies through traditional Portuguese products (e.g., Wine and Olive Oil) transforming both into creative Tourism Experiences that are often featured in tourism estates websites. Using a mixed methods methodology this study analyses 290 websites, in order to understand the emphasis given to internet information, promotion, users’ relation, transaction, interactivity, multimedia and design and social media areas. One limitation of this study is its circumscription to a specific wine region, the Douro. Another constraint is that it focus on only one perspective (supply). Future research should include a wider range of wine and olive oil territories, permitting a more systematic knowledge about the websites’ quality and efficiency, as well as exploring (supply & demand) creative experiences optics. A website analyse model is proposed aiming to evaluate the development level of wine & olive oil tourism.
L’olivotourisme en tant que produit touristique et culturel et son influence sur la dynamique des territoires
Authors: Lopes Eunice , Martins Pedro
Published: July 2024

Cet article propose d’explorer l’oléotourisme en tant que produit touristique et culturel et son influence sur la dynamique des territoires. Il est entendu que l’utilisation des ressources naturelles et culturelles existantes dans les territoires, comme produits touristiques différenciants, lorsqu’elle est cohérente et rigoureuse, peut être le facteur-clef de cohésion et de durabilité territoriale. La pratique de l’oléotourisme est fortement liée au développement touristique et culturel d’espaces plus naturels et ruraux, contribuant à l’appréciation et à la conservation de l’identité unique des lieux, à travers la promotion d’activités traditionnelles pouvant être vécues par les touristes. En ce sens, les stratégies de développement de produits basées sur l’huile d’olive et les oliviers sont pertinentes pour améliorer la connaissance du produit lui-même et son lien avec l’histoire et les traditions locales. L’augmentation du tourisme oléicole est présentée dans cette étude comme un défi pour le territoire (municipalité d’Idanha – Nova, Portugal), mettant en évidence la récupération de certaines activités développées pour revitaliser la cohésion territoriale.
L’utilisation de symboles dans les mouvements sociaux autochtones de Montréal : une « traduction interculturelle » ?
Authors: Tripotin Élisa
Published: July 2024

Les Peuples autochtones emploient une variété de symboles dans leurs luttes politiques et sociales dans la ville de Montréal. Ces symboles relèvent d’une certaine hybridité entre les impositions culturelles de la société dominante de descendance euro-canadienne et les traditions des nombreuses cultures autochtones du Canada. Les mêmes objets, vêtements et mises en scène sont employés par des activistes autochtones de Nations diverses révélant des référentiels identitaires communs souvent empreints d’une certaine homogénéisation. Pour autant, les Autochtones réinvestissent consciemment ces symboles participant à faire évoluer cette iconographie protestataire de façon constante. Cet article propose d’analyser l’utilisation de ces symboles dans l’activisme autochtone contemporain comme une forme de communication interculturelle, à la fois entre les Autochtones issus de Nations distinctes, mais également entre les Autochtones et le reste de la société. De plus, il illustre le potentiel de ces symboles dans l’évolution des représentations existantes envers les Autochtones.

Authors: Gosselin-Tapp Jérôme
Published: July 2024

Cet article examine la manière dont le contexte écologique et politique actuel (mondial et local) influence la légitimité des revendications autonomistes provenant de nations internes. Cette réflexion s’appuie sur une analyse normative du débat entourant la protection du caribou forestier au Québec en 2022 et 2023. Cette étude consiste en un examen des modalités de l’exercice des prérogatives québécoises en matière de politiques environnementales, en analysant notamment les relations entre le gouvernement fédéral, le gouvernement provincial québécois et les nations autochtones dont le territoire traditionnel se situe dans la province.
De l’Intelligence Artificielle et de la science des données pour aider à transformer l’Afrique
Authors: Kadio Offo Élisée
Published: July 2024

L’Afrique est une priorité globale de l’UNESCO et un axe important pour ses activités liées à l’Intelligence Artificielle (IA). Une réponse doit être apportée aux défis et au potentiel liés aux ressources humaines et aux développements techniques de l’Intelligence Artificielle sur le continent. De plus en plus, l’Intelligence Artificielle se trouve en filigrane dans les prises de décision. Nos vies sont régies de manière croissante par la diversité des applications techniques associées à cette technologie. Ces dernières, en l’espace de quelques microsecondes, parcourent des milliards de pages web, pistes numériques et données dérivées de capteurs sensoriels, produisant des informations sur la base d’algorithmes. Les données générées en Afrique risquent d’être exploitées au détriment des parties prenantes locales et d’être commercialisées à l’international au mépris de la vie privée. Cette étude se propose, à partir d’une approche analytique démonstrative, d’examiner l’exploitation accrue des données, qui peut booster le développement de l’Afrique si elle s’approprie l’Intelligence Artificielle. Toutefois, l’Intelligence Artificielle ne peut aller sans conséquences négatives, sur les plans économique, politique et social, accroissant ainsi la vulnérabilité du continent africain et surtout subsaharien.
L’interopérationnalité des services publics de transport dans la mise en œuvre du BRT à Abidjan et l’intelligence artificielle : les déterminants du défi de la compétence des parties prenantes
Authors: Koné Bassémory
Published: July 2024

Les technologies numériques ont progressivement envahi le continent Africain depuis près de quatre décennies, et s’inscrivent dans une perspective de transformation et d’amélioration de la qualité de vie des populations. L’expansion des technologies numériques a favorisé l’avènement de l’Intelligence Artificielle (IA). Dans le cadre de l’amélioration de la mobilité urbaine à Abidjan, l’Etat ivoirien promeut, à travers le Schéma Directeur d’Urbanisme du Grand Abidjan (SDUGA), de nouveaux moyens de transport collectif en sites propres à l’horizon 2025 sur les axes Nord-Sud et Est-Ouest de l’agglomération d’Abidjan. Une interopérationnalité s’impose entre les acteurs existants via des applications que doivent utiliser les acteurs et les usagers du transport public pour un système de transport multimodal. Rien ne garantit la bonne utilisation de ces outils et l’accessibilité facile à ces dispositifs innovants. La présente étude recherche, sous l’éclairage de la théorie de l’adoption des innovations ou des technologies, les déterminants de l’introduction réussie de l’IA dans la gouvernance de la mobilité urbaine à Abidjan.
L’abbaye de Lisle-en-Barrois (Meuse) : opportunités et contraintes spatiales d’un temporel cistercien frontalier
Authors: Wissenberg Christophe
Published: July 2024

Si l’abbaye de Lisle-en-Barrois, éphémère fondation canoniale, bénéficie désormais de l’édition de son chartrier pour le xiie siècle, les lacunes qui en grèvent l’approche spatiale ont entraîné le réexamen du corpus et surtout son extension à l’ensemble du volumineux cartulaire. En privilégiant l’exploitation du contenu des actes et son croisement avec le milieu et les sources cartographiques disponibles, l’enquête toponymique a permis de réduire les inconnues à une part négligeable, condition nécessaire à l’analyse spatiotemporelle qui fait objet de cette recherche. Le développement du réseau de granges met en évidence les initiatives épiscopales et les opportunités saisies dans une aire frontalière, mais aussi le contexte d’une vive concurrence monastique occasionnant in fine un temporel bipolaire. Outrepasser le cercle initial corseté – en gagnant les villes – et diversifier les approvisionnements (vin et sel) et les revenus (rentes) se conjuguent classiquement, au tournant du xiiie siècle, pour engager l’abbaye dans un processus d’adaptation – sinon d’abandon – de ses principes, en se calquant sur l’économie seigneuriale, dont la fondation de la villeneuve de Deuxnouds est l’incarnation la plus éloquente.
L’eau sur les habitats de l’âge du Fer. Une denrée rare ?
Authors: Verdin Florence
Published: July 2024

Peu d’études portent, pour les habitats de l’âge du Fer, sur leur alimentation en eau qui a laissé peu de traces : les populations se ravitaillaient par portage à partir d’un point d’eau (auprès de puits, sources, mares aménagées, fossés) ou récupéraient les eaux de pluie au moyen d’un dolium ou d’une citerne. Peu de constructions ostentatoires attestent d’équipements collectifs et ce sont les puits qui constituent l’équipement hydraulique le plus répandu, avec un net accroissement durant l’âge du Fer. Leurs aménagements intérieurs, quand ils existent, sont variables : cuvelage en bois, claies de branchage, pierre. Les aménagements extérieurs (margelles, etc.) ont rarement laissé de traces archéologiques. Aucun équipement de relevage de l’eau n’a été identifié jusqu’ici. Quant à ses usages, l’eau semble avoir eu une destination essentiellement familiale et domestique (rareté des équipements collectifs, dimensions des puits). Peu de rapprochements avec des lieux de production sont possibles. De même, le faible pourcentage de puits ayant livré des ensembles mobiliers ne favorise pas l’hypothèse de puits rituels.
L’aménagement hydraulique des sites cisterciens d’Auvergne et du Velay. Des procédés vernaculaires audacieux
Authors: Bouvard Emma
Published: July 2024

Les sites cisterciens de la région Auvergne héritent de terrains accidentés, caractérisés par des reliefs et un climat de moyenne montagne. Dans ce contexte, la maîtrise des ressources hydrologiques (résurgences, ruissellements de pentes etc.) est indispensable, avant tout pour se prémunir des dégâts qu’elles peuvent engendrer. Ainsi, les systèmes d’alimentation en eau des dix monastères évoqués dans l’article sont associés à des dispositifs de protection et de viabilisation des versants dominants. Afin de garantir un apport suffisant toute l’année aux communautés monastiques, ils sont souvent complétés par des canaux de dérivation captés sur le cours d’eau arrosant la vallée d’implantation ; ils se présentent sous diverses formes, du dalot de pierres sèches au simple canal à ciel ouvert (bief), et se développent sur des distances notables. Ces équipements participent à la mise en valeur du terroir sur la durée et appartiennent aux modes de construction traditionnelle que seule une démarche régressive et une approche taphonomique du paysage permet de rattacher à l’occupation monastique médiévale et moderne.
L’apprentissage et la maîtrise des langues étrangères chez les artistes en Russie au xviiie siècle
Authors: Tardy Hugo
Published: July 2024

Au xviiie siècle, les écoles d’art en Russie étaient confrontées à un problème de communication entre les professeurs, souvent étrangers, et leurs élèves russes. Cette problématique était commune à la formation des jeunes Russes dans diverses disciplines, y compris les sciences et les écoles militaires. Afin de remédier à cette situation, les académies ont mis en place des cours de langues étrangères pour leurs étudiants. Ces cours ont acquis une place centrale dans le parcours du futur artiste qui devait les pratiquer presque autant que le dessin, qui était la base, voire le seul cours de certaines académies en Occident. Au-delà d’être simplement des langues étrangères, elles sont devenues les langues dans lesquelles les arts étaient enseignés en Russie. L’émergence de la francophonie en Russie au milieu du siècle impacte évidemment l’apprentissage des langues, même si d’autres langues sont proposées aux étudiants chacune pour des raisons différentes – l’allemand dans le cadre de l’Académie des sciences, et l’italien pour les pensionnaires qui séjourneraient à Rome. Ainsi, à première vue, le choix des langues enseignées – allemand, français, italien – semblait être déterminé par les origines des professeurs, mais il répondait surtout aux orientations culturelles souhaitées par les classes dominantes.

Published: July 2024

High productivity and product quality are sought after by manufacturers due to the increasing demand for and use of plastic items. Injection molding is the most famous method used to make majority of the plastic items. Injection molding is however known for its lengthy production durations and poor product quality. This study shows the optimization of multiple design characteristics of circular cross-sectioned conformal cooling channels in response to reducing production time while improving product quality, at the same time, using Taguchi design-of-experiments approach. Diameter, depth, and pitch were the three main design variables examined. A Computer Aided Design software was used to create three dimensional designs and to conduct simulations. The responses obtained from simulations were time for cooling to ejection temperature, overall product shrinkage, extents of warpage and dimensions of sink marks. These output parameters were taken as input variables for multi-response optimization utilizing the method of Taguchi Grey Relational evaluation. The outcome obtained revealed that the minimum design variables resulted in the concurrent minimization of all responses for the particular geometry studied. Study of variance showed that the diameter to be the design factor that most significantly influenced all the responses simultaneously. Additionally, it was shown that conformal cooling channels yield better production outcomes than straight cooling channels whereby they gave the minimum cooling time and product defects. The optimized conformal cooling channels, when compared with straight cooling channels, reduced the time to cool the product, product shrinkage, dimension of warpage, and extent of sink marks by 29.35%, 5.99%, 19.77%, and 38.85% respectively.

Published: July 2024

Fibre-reinforced polymer (FRP) composites have many desirable properties such as high corrosion resistance and a high strength-to-weight ratio. They can also be easily optimised to suit different loading requirements. To produce functional components through 3D printing using FRPs, it is important to optimize the printing process parameters and to predict the mechanical properties of the printed components. The mathematical predictive approach is preferred over experiments it is flexible, fast and not as costly as experiments. In this work, a coupled finite element model for predicting flexural strength properties of additively manufactured parts is developed. The model takes into account the structure, material microstructure, and fused filament fabrication (FFF) process parameters in predicting the flexural strength of parts. The validity of the model is tested using a standard flexural bending specimen and an ankle-foot orthosis (AFO) prototype which are fabricated using short carbon fibre-reinforced polyamide 12 (PA12-CF) filament. The validity of the coupled analysis model was tested by comparing the model predictions of flexural strength with experimental results. The results provide a good prediction of part performance.
An Analytic Model for the 2-DEG Density Current-Voltage Characteristic for AlGaN/GaN HEMTs
Authors: El Yazami Chaimae , Bri Seddik
Published: July 2024

Higher frequency hetero-junction transistors called High Electron Mobility Transistors (HEMTs) are employed in a number of high-power applications, including radiofrequency, radiation, space exploration, and others. When stressed between the junction of a broad bandgap and low bandgap material, AlGaN/GaN HEMTs create Two-Dimensional Electron Gas (2DEG).To determine the eventual number of electrons in the quantum well, it is necessary to assess the charge density generated by the polarization existing in the 2DEG region. In this paper, two-dimensional electron gas (2-DEG) sheet carrier concentration estimate model takes into consideration the substantially dominating total polarization. In order to regulate the impact of these characteristics on the device performance, discussion has focused on the current-voltage characteristic, which illustrates how the drain-source current varies in response to the gate voltage modulation. Our study also aims at how the two-dimensional electron gas density depends on the aluminum molar percentage and AlGaN layer thickness.
Practical Exploration of the 'Open or Close' Concept: Evaluation of the Hygrothermal Performance of a Bioclimatic Innovation for Onion Bulb Preservation
Authors: Ouedraogo Boukaré , Kabore Boureima , Ouedraogo Germain , Palm Kalifa , Bahiebo Dieudonné Joseph
Published: July 2024

Substantial losses occur during the storage of onion bulbs due to the inadequacy of available preservation technologies. In an endeavor to contribute to a solution, we evaluate the thermal efficacy of a bioclimatic innovation known as the "solar cell" for onion bulb preservation. This assessment involves recording temperature data from both external and internal walls, as well as indoor and outdoor air temperatures, solar irradiation, and relative humidity levels indoors. These measurements offer insights into crucial performance parameters such as thermal phase shift, thermal inertia, thermal decoupling between internal and external environments, relative humidity, damping factor, and thermal amplitude. Furthermore, we examine the impact of external factors, including external temperature and solar radiation. Across different facades, the thermal phase shift of the chamber's structure averages between 5.5 and 10.87 hours. Notably, the maximum thermal phase shift is observed to be 11.67 hours on the Eastern wall. The lowest recorded thermal damping factor is 0.081 on the Western wall, while the highest is 0.337 on the Northern wall. The study of thermal decoupling between the internal and external environments reveals a potential temperature differential of 13.7°C and 9.5°C during the day, and-6°C at night, contingent on the time of year. Consequently, the "close or open" operational mode proves to be of significant interest. Exposed to solar radiation peaking at 1041 W/m2, the temperatures of the external facades of the walls experience a substantial increase, reaching up to 52.3°C. Meanwhile, the internal environment maintains a thermal range of 24.21°C to 31.68°C under a maximum airflow of 0.18 m/s. The average relative humidity within the storage chamber fluctuates between 42.65% and 87%. Hence, the solar cell demonstrates its capacity to create optimal conditions of 25°C-30°C and 0.062 m/s for onion bulb conservation. Nevertheless, further enhancements are warranted for effective humidity control.
An Investigation of the Mechanical and Durability Properties of Hollow Concrete Blocks Made with Copper Mine Tailings as a Partial Cement Replacement

Published: July 2024

The increase in copper productivity in Zambia has resulted in the expansion of disposal areas occupied by mineral wastes and tailings. This not only consumes land but also, due to insufficient management, poses negative environmental impacts and health risks to people. Therefore, efficient and sustainable approaches for the proper management of these waste materials must be developed. In this study, the potential utilization of copper mine tailings was assessed. After analyzing the physical and chemical properties of copper mine tailings from Kitwe Tailings Dam (TD25), hollow concrete block specimens were prepared. Copper mine tailings were used as a partial replacement for cement in the mix design, with replacement ratios as follows: 0% for CBCMT O% (control specimen), 10% for CBCMT1O%, 20% for CBCMT2O%, 30% for CBCMT3O%, 40% for CBCMT4O%, and 50% for CBCMT5O%, all aimed at achieving a target strength of 5 MPa. Specimen compressive strength was evaluated, and it was found that CBCMT1O% and CBCMT2O% achieved the target compressive strength at 28 days of age. Water absorption rates and resistance to acid attack were also assessed. Findings revealed that all specimens outperformed the control specimen in terms of these properties. Furthermore, the environmental feasibility of the hollow concrete blocks specimens was examined, and the results showed limited leaching of heavy metals from the specimens, with concentrations within permissible thresholds. Additionally, a statistical analysis was conducted to study the influence cell shape has on the specimens’ compressive strength. Aimed at identifying the optimal specimen type for achieving compressive strength at an early age, results indicated that cell shape had a significant impact on the 28-day age of hollow concrete blocks. The study proposes a novel copper mine tailings (waste) management approach, by utilizing the potential it has to replace cement in the production of hollow concrete blocks, evident from the observed enhancement of the mechanical and durability properties.

To study the influence of cement-sand ratio, fly ash content, steel slag content, and fiber content on the performance of iron tailings premixed dry mixed mortar based on Box-Behnken, the regression model of compressive strength and fiexural strength and the above four factors was established, and the optimized mix ratio parameters were obtained. The results showed that the significance of the effect on compressive strength is ranked as follows: cement-sand ratio is greater than fly ash content than steel slag powder content than fiber content, and the significance of the effect on flexural strength is ranked as follows: cement-sand ratio is greater than fiber content than steel slag powder content than fly ash content.
Evaluation and Comparison of Breach Parametric Model for Embankment Dams
Authors: Geremew Getachew Bereta
Published: July 2024

Reliable approximations for breach parameters using a parametric model due to embankment dam failure are very significant factors in dam safety and mitigation measures. Therefore, utilizing information on historically unsuccessful embankment dams, several empirical models have been formulated by different researchers. There is still no universal method for calculating the occurrence of dam breaches. The main objective of this research is to evaluate and compare the selected parametric dam breach models that are available in the literature. Four models (Xu et al., Vescher et al., Froehlich, and USB Reclamation) were chosen to forecast the breach event's parameters and peak discharges. Historically, 59 failed embankment dams’ data in various countries around the world were used. In order to assess and compare the breach models and recommend the best-performing model for predicting the peak discharge, breach width, and failure time, ten (10) statistical quantitative indicators were used. The breach model developed by Xu et al. has good performance. Finally, to show the impacts of erodibility, validation, and sensitivity of the selected model, it was checked using eight dams’ data. During the validation, the calculated and observed results were in agreement. Sensitivity revealed that large fluctuations in the breach parameter and peak discharge were seen when the erodibility coefficient increased or decreased.
Current Clinical Concepts: Rehabilitation of Thoracic Outlet Syndrome
Authors: Hock Greg , Johnson Andrew , Barber Patrick , Papa Cassidy
Published: July 2024

Thoracic outlet syndrome (TOS) involves inconsistent symptoms, presenting a challenge for medical providers to diagnose and treat. Thoracic outlet syndrome is defined as a compression injury to the brachial plexus, subclavian artery or vein, or axillary artery or vein occurring between the cervical spine and upper extremity. Three common subcategories are now used for clinical diagnosis: neurogenic, arterial, and venous. Postural position and repetitive motions such as throwing, weightlifting, and manual labor can lead to symptoms. Generally, TOS is considered a diagnosis of exclusion for athletes due to the poor accuracy of clinical testing, including sensitivity and specificity. Thus, determining a definitive diagnosis and reporting injury is difficult. Current literature suggests there is not a gold standard diagnostic test. Rehabilitation has been shown to be a vital component in the recovery process for neurogenic TOS and for arterial TOS and venous TOS in postoperative situations.
Ascitic Fluid in Ovarian Mass with Special Reference to Paired-box Gene 8 Immunoexpression: A Cross-sectional Analysis
Authors: Mahato Prabhat , Das Chhanda , Saha Rama , Mandal Ankita Pranab , Kamilya Gourisankar
Published: July 2024

Introduction:

Mortality in the case of ovarian malignancy is high due to late diagnosis. Early and accurate diagnosis can improve case-specific management. Paired-box gene 8 (PAX8) has proved to be expressed in the ovarian epithelial cells and is considered a new biomarker for early diagnosis. Case–control studies show that the level of PAX8 in the serum and tissue expressions are positively correlated and increased in ovarian malignancy, especially in the high-grade serous type, the most common variety of ovarian malignancies.

Aims:

The aim of this study was to assess the epidemiological spectrum of ovarian neoplastic lesions and a comparative study of conventional cytology and a cellblock of ascitic fluid and subsequent PAX8 immunohistochemistry (IHC) expression to diagnose ovarian neoplasm.

Materials and Methods:

We collected clinical data from participants using a predesigned pro forma. We made a cytological diagnosis using conventional cytology, followed by cellblock preparation and subsequent assessment of PAX8 IHC expression. Ascitic fluid received for cellblock was centrifuged, tissue sediment was mixed with plasma, and then drops of thrombin were added. We fixed the clotted sample by adding 10% formalin for 30 min. The formalin-fixed, paraffin-embedded cellblocks were sliced into 4–5 μ sections and stained with hematoxylin and eosin. Subsequently, we used an immunohistochemical stain for PAX8 expression to diagnose ovarian malignancy.

Results:

We received 55 ascitic fluid samples. On cytological smear examination, 12 (21.8%) cases were benign, 35 (63.6%) were malignant, and the remaining 8 (14.6%) were suspicious of malignancy. On histological examination of cellblock preparation, 43 (78.2%) were malignant cases, and among these 43 cases of cellblocks studied, 37 were positive for PAX8 status; six were negative for PAX8. There was a statistically significant association between malignant cell positivity and PAX8 status in the cellblock (P < 0.001).

Conclusion:

An evaluation of PAX8 status in ascitic fluid cellblock study should be considered for high-grade ovarian cancers in patients who may benefit from targeted therapies. Patients with ovarian mass and ascites can be evaluated for PAX8 status in their ascitic fluid cytology study for the purpose of neoadjuvant chemotherapy.
Histological Depth of Burn with Bipolar Plasma Arc – Is That the Cause for Urethral Sphincter Damage in Bipolar Transurethral Resection of the Prostate?
Authors: Londhe Sambhaji , Suhas D. S. , Sinha Maneesh
Published: July 2024

Introduction:

The bipolar plasma button is gaining acceptance as a modality to perform endoscopic enucleation of the prostate. The plasma arc during activation of the button electrode extends for a distance beyond the edge of the evaporated area as seen on endoscopy. The extent of tissue affected by the intense heat of the arc is not certain. The histologically measurable depth of burn may have relevance during apical dissection, where thermal spread has been implicated in sphincter injury.

Objectives:

Our objective was to assess the histological depth of burn in animal tissue using a bipolar button electrode.

Materials and Methods:

Using a KENTAMED hARTT 400 electrosurgical unit machine, the following cuts were made over three freshly acquired goat liver specimens in a normal saline bath: (a) 280 W single superficial cuts using cutting current, (b) 280 W multiple deep cuts in the same groove using cutting current, and (c) 140 W, 2 s contact with coagulation current. Samples were fixed in neutral buffered formalin and processed paraffin embedded, and sections were stained with hematoxylin and eosin. The extent of thermal effect beyond the evaporated tissue edge was assessed on histopathology by a senior pathologist.

Results:

The histological depth of injury (involving about 5–6 rows of hepatocytes) did not extend more than 0.5 mm beyond the grossly visible edge of evaporated tissue.

Conclusions:

We found that the histological depth of burn in animal tissue extended only 0.5 mm beyond the grossly visible edge of the evaporation defect unlikely contributing to sphincter injury.
Innovations in Urology – What? How?
Authors: Kannan Krishnasamy
Published: July 2024

The human brain is inquisitive and is well-equipped to find an alternative/solution to many of the problems faced. These alternatives or solutions are synonymous with innovations. The innovation can be anything and there is an endless list of the variety of innovations. Such alternatives/solutions so thought about must be recorded for further reference, as they are baby steps before a giant leap. The “Innovations Galore” journey started in Chandigarh USICON in 1996 and extended to 17 editions apart from presenting some individual innovations also. Notable among those is the ash bag used as a temporary solution for urine leak in malignant vesicovaginal fistula, later extended to other similar indications. The basis of such innovations involves an out-of-the box thinking to find a way out of a problem. A successful innovation must be repeatable and easily reproducible. The roadmap to an innovation involves steps such as identifying the problem, trying a solution, logical analysis of the solution, an effort to overcome/minimize the cons of the decided solution, and an objective evaluation of the same by a self-assessment by a scoring system.

Published: July 2024

Introduction: Dentofacial harmony can be improved with orthodontic treatment. As people age, there is an increasing need for orthodontic treatment; this is true for both adults and children. This study aimed to determine how the activity of transforming growth factor beta-1 (TGF-β1) differs between young and old rats and what happens to the TGF-β1 level following honey intake. Materials and Methods: Twelve Sprague-Dawley rats (n = 12) were randomly divided into four groups: young rats without honey administration, young rats with honey administration (YH), old rats without honey administration, and old rats with honey administration (OH). To move the teeth distally, orthodontic brackets are inserted on the maxillary incisors with an open coil spring positioned between the teeth. The honey (YH and OH) groups received honey at a dose of 0.4 mL/200 g body weight daily for 14 days, and gingival crevicular fluid samples were collected on days 0, 1, 7, and 14 for all groups. Enzyme-linked immunoassay was used to assess TGF-β1 levels. Results: The results of a three-way analysis of variance and Tukey’s post-hoc tests revealed that the TGF-β1 levels in young rats on days 0, 1, 3, 7, and 14 were noticeably higher than those in older rats (P < 0.05). Young and old rats that received honey had considerably greater TGF-β1 levels than the control rats (P < 0.05). Conclusion: The results indicate that the TGF-β1 levels in young rats were much greater than those in older rats, and honey could increase the TGF-β1 levels in old rats during active orthodontic tooth movement.

Authors: Koul Rahul , Datana Sanjeev , Roy Indranildeb , Saxena Vivek
Published: July 2024

Introduction:

Maxillofacial injuries in children and adolescents always present a challenge due to the peculiar facial anatomy in children. This study aimed to determine the characteristics and pattern of traumatic maxillofacial injuries in children and adolescents reported to outpatient departments of two tertiary care health centers.

Materials and Methods:

Present study had a retrospective design, and the hospital records of all children and adolescent patients aged between 0 and 18 years, who had undergone maxillofacial fractures and were admitted for the same to two tertiary care health centers between January 2012 and May 2022 were reviewed.

Results:

77 patients suffered maxillofacial trauma with 115 fractures. The leading cause of maxillofacial trauma in the study was found to be road traffic accidents (RTA) followed by falls and sports-related injuries. Maxillofacial trauma was observed more in boys than girls, with an M: F ratio of 3.8:1. Out of 77 patients in the present study, more than half (51.9%) suffered maxillofacial trauma involving the lower one-third of the face, followed by the middle third (45.5%) and upper third (2.6%). A total of 11 patients (14.2%) were treated within 24 hr of sustaining injury. The majority of the patients, (n = 68; 88.3%) underwent open reduction and rigid internal fixation (ORIF), while 9 patients (11.7%) underwent closed reduction.

Conclusions:

Pediatric maxillofacial trauma was mainly attributed to road traffic accidents. Lower one-third of faces were more commonly affected and an increasing trend of maxillofacial trauma was observed with age.
Comparative evaluation of salivary, serum, and GCF alkaline phosphatase levels in chronic periodontitis patients before and after nonsurgical periodontal therapy: A clinico-biochemical study
Authors: Parihar Sarita , Singh Preeti , Srivastava Ragini , Srivastava Atul , Imran Fouzia , Vishnu JP

Background:

Chronic periodontitis is a multifactorial disease that causes the supporting tissues around the teeth to become inflamed and destroyed, which further causes tooth mobility and eventual tooth loss. The enzyme alkaline phosphatase (ALP), which is involved in bone resorption and gingival inflammation, is an important biomarker. The current study’s objective is to compare the serum, gingival crevicular fluid (GCF), and salivary levels of ALP in individuals with chronic periodontitis before and after nonsurgical periodontal therapy.

Materials and Methods:

On the basis of clinical and radiographic examinations, 72 participants were split into two groups: Group I (healthy individuals) and Group II (chronic periodontitis patients). All patients who were in an aseptic condition had their serum, GCF, and unstimulated saliva taken, and samples were then tested for ALP levels using ALP kit.

Results:

The difference in salivary, serum, and GCF ALP levels between the control group (23.44 ± 4.76, 58.88 ± 8.29, and 776.76 ± 121.91) and the study group (105.66 ± 16.33, 102.38 ± 4.43, and 1,825.77 ± 275.12) was found to be statistically significant with P < 0.001. The difference in salivary, serum, and GCF ALP levels from baseline (105.66 ± 16.33, 102.38 ± 4.43, and 1,825.77 ± 275.12) to postoperative (49.54 ± 5.69, 83.46 ± 4.22, and 1,148.38 ± 129.01) was found to be statistically significant with P < 0.001. The results demonstrated that patients with chronic periodontitis have considerably higher levels of serum, GCF, and salivary ALP than healthy individuals.

Conclusion:

Salivary and GCF ALP can thus be used as a key inflammatory diagnostic biomarker in periodontal diseases.
Illuminating the shadows: an insight into periorbital hyperpigmentation
Authors: Awal Guneet , Kaur Navleen , Shubham
Published: July 2024

Periorbital hyperpigmentation (POH), also referred to as periorbital melanosis or dark eye circles, is a common dermatological concern characterized by darkening of the skin around the eyes. This review article aims to comprehensively analyze the current understanding of POH, encompassing its epidemiology, etiopathogenesis, clinical manifestations, diagnosis and available treatment modalities, and focusing on patients’ skin color. The review also consolidates a grading system for POH and emphasizes the importance of accurate diagnosis using clinical examination, assessment scores, Wood’s lamp, ultrasonography, and dermoscopy. Treatment modalities range from non-pharmacological measures to topical agents, including kojic acid, alpha-arbutin, vitamin C, vitamin E, niacinamide, retinoids, and hydrating agents. The manuscript explores the efficacy of various skin-lightening agents, such as hydroquinone, and introduces emerging treatments like caffeine, carotenoids, lactic acid, curcumin, and vitamin K. Additionally, it delves into procedural treatments like chemical peels, lasers, blepharopigmentation, mesotherapy, platelet-rich plasma therapy, fillers, autologous fat transplantation, and surgical interventions. The comprehensive approach to understanding and managing POH presented in this review aims to provide clinicians with valuable insights into the diverse therapeutic options available for this challenging cosmetic concern.

In this paper, we delve into the transformative influence of Large Language Models (LLMs) in the financial sector. Through meticulous exploration, we uncover the multifaceted applications of LLMs, ranging from elevating customer support and fortifying fraud detection to reshaping market analysis and prediction. LLMs, with their unparalleled ability to process extensive textual data, bring forth innovative solutions and insights. However, we also address critical challenges such as user trust and ethical considerations, emphasizing the need for responsible integration. Collaborative efforts between industry stakeholders and researchers are essential prerequisites for making a pivotal stride towards a future where LLMs redefine financial practices, with efficiency, accuracy, and ethical precision shaping the industry’s evolution.
Incidence and Severity of Erectile Dysfunction in Chronic Kidney Disease Patients Undergoing CAPD and Hemodialysis: A Systematic Review and Meta-analysis
Authors: Dahril Dahril , Pramono Indrayudha
Published: July 2024

Background: Erectile dysfunction (ED) is an adverse effect of chronic kidney disease (CKD) treatment that can reduce patients’ quality of  life. Consequently, the purpose of this study is to assess the incidence and severity of ED in CKD patients who have undergone continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis.
Methods: We performed a systematic search on several electronic  reference databases (PubMed, ScienceDirect, Web of Science, and Cochrane). Inclusion criteria are articles published in English, full-text  availability, and articles published between 2001 and 2023. The reviewed studies were observational studies. The studies analyzed either CAPD or hemodialysis.
Results: A total of 15 studies were included. ED in patients with CKD who had undergone CAPD and hemodialysis  varied, ranging from 51.84% to 80.5%and 56% to 89%, respectively. A pooled estimate showed that CKD patients who underwent  hemodialysis had higher odds of developing ED (odds ratio [OR]=12.56; 95% confidence interval [CI]=6.37–24.77; p<0.001) compared with  those who underwent CAPD (OR=8.02; 95%CI=1.64–39.15; p=0.01). Regarding the laboratory outcomes, no significant differences were  found in creatinine serum (MD= −1.08; 95%CI= −3.21 to 1.06; p=0.32) and hemoglobin levels (MD= −0.38; 95%CI= −1.05 to 0.30; p=0.27)  between CKD patients who underwent dialysis, either with or without ED.
Conclusion: ED is prevalent among patients undergoing  hemodialysis. In addition, hemodialyzed patients exhibited more severe levels of ED compared with CAPD patients. Therefore, we suggest  CAPD for CKD patients with ED.

Published: July 2024

Results of butterflies sampled as by-catch in Malaise traps deployed in indigenous forests at Parc National de Nouabalé-Ndoki, Republic of Congo are presented. Using traps deployed with cyanide as a killing agent, rather than the standard ethanol, 153 species of butterfly belonging to five families were sampled, which constituted nearly one-third of the butterfly species known from the Park, with numerous species not encountered during general collecting. The benefits and drawbacks of using this technique, as well as the potential for these traps to be used as part of future butterfly inventories are discussed. The species samples are presented in a tabulated form.Résumé: Les résultats des papillons de jour échantillonnés comme prises accessoires dans les pièges Malaise déployés dans les forêts indigènes du Parc National de Nouabalé-Ndoki, République du Congo sont présentés. En utilisant des pièges déployés avec du cyanure comme agent letal, plutôt que de l’éthanol standard, 153 espèces de papillons de jour appartenant à cinq familles ont été échantillonnées, ce qui constituait près d'un tiers des espèces de papillons connues dans le parc, avec de nombreuses espèces non rencontrées lors de la collecte générale. Les avantages et les inconvénients de l'utilisation de cette technique, ainsi que la possibilité d'utiliser ces pièges dans le cadre de futurs inventaires de papillons, sont discutés. Les espèces échantillonées sont présentés sous forme de tableau.
Inwigilacja a prywatność. Dyskursy o systemie Pegasus w wybranych mediach
Authors: Seklecka Aleksandra , Brodzińska-Mirowska Barbara
Published: July 2024

Debata o prywatności jest skupiona dziś mocniej na masowej inwigilacji wspieranej przez system Pegasus. Dlatego warto przyjrzeć się, jak w debacie publicznej kształtuje się inwigilacyjny i zorientowany na Pegasusa dyskurs ramowany przez różnych aktorów. Celami badań są: C1: wyodrębnienie aktorów tworzących dyskurs medialny na temat sprawy Pegasusa; C2: analiza kontekstów, w jakich ten dyskurs był tworzony; C3: poszukiwanie ram, jakie wyłoniły się z badanych materiałów. Badamy ramy dyskursywne, w jakie aktorzy ujmują inwigilację jako kategorię polityczną, oraz jakimi wymiarami nadzoru się zajmują. Korpus danych stanowią polskie, wybrane media opiniotwórcze. Badania prowadzono metodami jakościowymi: jakościową analizą treści do zbierana danych oraz analizą dyskursu w badaniu ramowania nadzoru i kontekstu użycia Pegasusa. Ponadto użyto ilościowej analizy treści do kategoryzacji i porównania dyskursu w badanych mediach. Analizy pokazały, że dyskurs dotyczący inwigilacji Pegasusem został zdominowany przez kontekst polityczny, instytucjonalny oraz dyskusje wokół takich kwestii, jak „praworządność i demokracja”, zaś ramy dyskursu poszczególnych polityków i dziennikarzy znacznie się od siebie różniły.

Çocukların boy ortalaması 111.89 ± 5.5 ve ağırlık ortalaması 22.41±3.9’dur.Ebeveynlerin görüşmelerinden elde edilen veriler doğrultusunda fiziksel, bilişsel, psikososyal güçlükler ve davranışsal problemler olmak üzere dört tema elde edilmiştir.
Sonuç: 60-72 aylık çocukların fiziksel, bilişsel, psikososyal güçlükler ve davranışsal problemler yaşamaktadır. Çocukların okula uyum ile ilgili yaşadığı güçlükler, en çok çanta taşıma, öz bakımı yerine getirme ve yazı yazmada zorlanmadır. Bu sonuçlara göre çocukların 72 aydan önce ilkokula başlamasının gelişimsel olarak uygun olmadığı söylenebilir.
UM NOVO SÉCULO DELEUZIANO
Authors: Milovic Miroslav
Published: July 2024

Uma vez Michel Foucault articulou a esperança de que o século 20 seria chamado o século deleuziano, mas isso não aconteceu. Nós ainda temos a esperança de que o século que vem tenha essa possibilidade. Sobre isso, saiu agora o livro Gilles Deleuze: Uma Vida Filosófica. É um bom sinal para o século que começa. Mas por que Deleuze? Por que tantas esperanças com sua filosofia?
