Published: August 2023

The crystal structure, piezoelectric and magnetic properties of BiMn1-xFexO3 (x ≤ 0.4) solid solutions synthesized using different solid state reactions from a stoichiometric mixture of simple oxides at high pressures and temperatures have been studied. The structure of the composition undergoes a concentration phase transition from the monoclinic to the orthorhombic structure. The formation of the orthorhombic phase is observed at the concentration x ≈ 0.2 and is accompanied by the destruction of the dz2 orbitals of the Mn3+ ions causing the stabilization of a homogeneous magnetic state. The solid solutions containing 0.2 ≤ x ≤ 0.4 exhibit a non-zero piezoresponse and may have ferroelectric or magnetic domain structures, the ferroelectric switching voltage decreasing with an increase in the iron concentration while the remanent magnetization decreases. The highest piezoresponse signal is observed for the BiMn0.7Fe0.3O3 solid solution. The relationship between the chemical composition, type of crystal structure, piezoelectric and magnetic properties of the BiMn1-xFexO3 solid solutions has been verified. Due to the combination of magnetic and electric dipole ordering these materials show good promise for practical applications.
Radically local supply chains through territorial brands: Insights from the 100% Local project
Authors: Godina Golija Maja
Published: August 2023

The modernization of food supply chains has marginalized remote agricultural regions such as the Alps. As a result, local actors often adopt new ways of producing, promoting, and selling their products by differentiating them in the eyes of consumers. The labelling of quality local agri-food products through the development and promotion of territorial brands play an essential role in this respect. In the article we address the research question: What are the conditions for the creation, development and sustainability of territorial brands in the agri-food sector? What are the characteristics of some territorial brands, which are an essential development factor and the subject of local identities and local policies? We discuss cooperation between local, regional, and national actors. The aim of this article is to highlight the preparation and role of the 100% Local Model for the successful creation and development of territorial brands in the field of agro-food production in the Alps.
Renouvellement des représentations de l’âge du Bronze en Bretagne
Authors: Blanchet Stéphane
Published: August 2023

Favorisée par le développement de l’archéologie préventive et les politiques de prescription adoptées par le SRA de Bretagne, la multiplication des découvertes et des opérations concernant l’âge du Bronze a transfiguré nos connaissances sur les habitats ou encore les pratiques funéraires de cette période. Les données nouvelles rendent possible la mise en évidence de sites en interaction, de réseaux locaux, voire régionaux. Elles offrent aussi une meilleure perception des différentes dynamiques culturelles et plus largement des mutations du système social et économique qui ont touché la région entre le milieu du iiie millénaire et le début du ier millénaire avant notre ère.
Villes disparues, oubliées, retrouvées. Dynamique de recherche sur les agglomérations laténiennes dans l’Ouest de la France
Authors: Goff Elven Le
Published: August 2023

Longtemps resté à l’écart de la recherche sur le sujet des agglomérations de la fin du second âge du Fer, le nord-ouest de la France semblait presque se placer en marge du reste de l’Europe celtique et être peu concerné par le phénomène d’urbanisation. Depuis les années 2000, la constitution progressive d’un important corpus de sites montre que ce secteur géographique s’inscrit en réalité pleinement dans le processus de développement du phénomène d’urbanisation tel qu’il se manifeste ailleurs dans le monde celtique. Il présente même aujourd’hui un contexte assez bien documenté, illustré par un nombre important de récentes découvertes d’agglomérations fortifiées et non fortifiées, dont de nombreux sites étudiés sur de vastes superficies permettent d’aborder la question de la morphologie des espaces urbains et de l’urbanisme laténien. La dynamique de recherche engagée au cours de ces deux dernières décennies a également débouché sur plusieurs publications de synthèse et travaux universitaires et s’ouvre aujourd’hui sur un programme collectif de recherche sur l’organisation des réseaux d’agglomérations laténiennes au sein de leurs territoires anciens, pour les régions administratives Bretagne et Pays de la Loire.
Archéologie préventive et archéologies environnementales. L’exemple de la basse vallée de la Seine
Authors: Fajon Philippe , Marcigny Cyril , Riche Caroline
Published: August 2023

La basse vallée de la Seine a été le théâtre de plusieurs expériences, associant la lecture du rythme d’implantation des occupations humaines et la restitution des paléoenvironnements. D’abord cantonnée à des travaux ponctuels, cette dynamique de recherche a pu, dans le cadre de la loi de 2001 qui permettait de sortir de « l’archéologie négociée », être très largement élargie au potentiel d’investigations qu’offrait l’archéologie préventive. Les carrières de sables et graviers, correspondant à des espaces alluviaux, véritable mémoire sédimentaire de la vallée, ont donc très rapidement constitué un champ d’investigation des plus prometteurs, permettant d’élargir la notion de « patrimoine à conserver par l’étude » à la géoarchéologie. Il est ainsi possible de proposer une véritable caractérisation des paysages anciens via l’observation multiscalaire, dans le temps, et l’espace, des composantes topographiques, géologiques, végétales, faunistiques, morphologiques et anthropiques d’un milieu.
À Soissons, une synergie pour révéler l’histoire de la ville
Authors: Hugonnier Louis , Fronty Richard , Audebert Alexandre
Published: August 2023

Depuis une vingtaine d’années, le territoire soissonnais connaît un regain d’activité archéologique dans le prolongement d’une politique de prescription ciblée face à une augmentation des projets d’aménagement extra et intra muros. Dépassant les contraintes spécifiques liées au diagnostic préventif en ville comme la faible surface d’investigation, les agents de l’Inrap documentent progressivement la structure urbaine, l’afflux de données brutes se confrontant alors aux postulats archéologiques connus. Cette confrontation positive s’illustre, à travers les exemples de la ville du Haut-Empire, du quartier Saint-Waast et de la question des enceintes urbaines, par un affinement des schémas connus, une remise en cause de certains postulats et l’établissement de réflexions inédites sur des espaces archéologiques méconnus. Cette situation conduit donc à la mise en place d’un PCR sur le fait urbain à Soissons, nécessité étant de donner du sens aux multiples informations issues de l’archéologie préventive.
Les données paléoenvironnementales sur les sites archéologiques. Constats et retours d’expérience
Authors: Nectoux Élise , Guilbeau Denis , Ihuel Ewen , Cabanis Manon
Published: August 2023

Dans le cadre des opérations archéologiques, les données paléoenvironnementales ont toujours eu un statut particulier. Leur prise en compte n’est pas nouvelle, mais n’a vraiment été formalisée que dans les dernières décennies et a encore été renforcée par les derniers textes législatifs. Malgré ce cadre réglementaire national, les disparités entre les régions sont très importantes, à la fois en raison des conditions environnementales, avec une conservation très différente des écofacts selon les contextes, et en raison du cadre administratif et scientifique, la répartition géographique des compétences relatives aux sciences du paléoenvironnement étant très inégale à l’échelle de la France. L’exemple vertueux du développement des études carpologiques en Auvergne dans le cadre d’une collaboration SRA-Inrap montre toutefois que ces disparités régionales peuvent très largement être surmontées par une politique volontariste qui permettra à terme d’amplifier considérablement notre état des connaissances du paléoenvironnement à l’échelle nationale.
Trente années de recherche sur les pratiques funéraires coloniales à la Martinique et à la Guadeloupe
Authors: Romon Thomas
Published: August 2023

Ces trente dernières années ont vu l’essor de l’archéologie historique, concernant donc l’époque coloniale, sur les territoires de la Martinique et de la Guadeloupe. Ce développement, concomitant de la professionnalisation de la discipline, a également touché l’archéologie funéraire. C’est par cette spécialité que, initialement, l’esclave a pu être appréhendé. En effet, une fois sa sépulture reconnue, celle-ci permet d’accéder à sa biologie, mais aussi à ses gestes. Quelles sont les pratiques funéraires en usage dans les colonies françaises des Antilles ? Quelle place y occupent les esclaves ?
Prescrire de l’archéologie préventive sur des sites de la Seconde Guerre mondiale en France. Une politique qui va de soi ?
Authors: Carpentier Vincent , Fichet de Clairfontaine François
Published: August 2023

Si la légitimité de l’archéologie de la Seconde Guerre mondiale est encore discutée et que les chercheurs français engagés dans l’étude des grands conflits du XXe siècle restent peu nombreux, ces derniers sont parvenus néanmoins à jeter les fondations d’un questionnement novateur sur ces vestiges particuliers. L’examen des opérations menées à travers le territoire national met en lumière d’importantes disparités d’une région à l’autre, en même temps que la part déterminante de l’archéologie préventive dans l’émergence de cette spécialité. S’en dégagent trois grandes catégories de site qui font l’objet de la plupart des prescriptions : des lieux d’internement, des zones de stationnement de troupes en lien avec les phases de combat et des ouvrages défensifs du Mur de l’Atlantique. Les problématiques qui en découlent sont aujourd’hui mieux maîtrisées et contribuent au renouvellement des connaissances relatives au conflit, en mettant l’accent sur la matérialité des combats et l’histoire des comportements.
Vingt ans de géophysique à l’Inrap
Authors: Hulin Guillaume , Simon François-Xavier
Published: August 2023

Si les techniques géophysiques sont développées depuis des décennies pour les questions archéologiques, leur application dans le contexte de l’archéologie préventive française n’a pas toujours été évidente. Ce n’est que très récemment que leur intégration a connu une forte évolution, faisant désormais de la géophysique un outil à part entière à disposition des archéologues. Les progrès technologiques ont bien sûr permis de faire évoluer cette discipline, mais cette évolution n’aurait pu se faire sans un changement de perception global des applications possibles et des limites inhérentes à ces techniques d’imagerie du sous-sol. Divers travaux, notamment ceux issus du projet canal Seine — Nord Europe, puis la création, au sein de l’Inrap, d’une cellule dédiée à la géophysique ont véritablement permis un changement de paradigme et une appropriation de cet outil par les équipes archéologiques.
L’archéothanatologie en contexte préventif. Évolution des protocoles et des enjeux
Authors: Bizot Bruno , Richier Anne
Published: August 2023

L’évolution récente de la discipline étudiant les morts anciens, nommée aujourd’hui « archéothanatologie », a permis de grandes avancées en termes d’enjeux et d’objectifs. Depuis une vingtaine d’années, la discipline a ainsi élargi ses champs de compétence et enrichi ses outils d’analyse, à la faveur des progrès du numérique, de la géomatique et des archéosciences. La quantité et la diversité des sites funéraires et mortuaires fournies par l’archéologie préventive offrent un terrain d’investigation particulièrement propice à cette évolution disciplinaire, au niveau tant de la collecte des données de terrain que de l’étude biologique des restes osseux et des analyses physico-chimiques. Il reste toutefois des pistes à approfondir ou à explorer, concernant notamment la taphonomie de l’os et du squelette, les protocoles de fouille et d’étude, les socles méthodologiques partagés, les partenariats avec les laboratoires et la mise en perspective socioanthropologique des résultats.
Prescrire de l’archéologie en milieu humide. L’expérience néo-aquitaine
Authors: Gaillard Hervé , Loubignac Fabien , Ihuel Ewen , Gestreau Raphaël , Detrain Luc
Published: August 2023

La restitution de la continuité écologique des cours d’eau définie par la loi-cadre de 2016 a amené les services régionaux d’archéologie (SRA) à inventer un protocole d’étude sur les vestiges archéologiques menacés des milieux humides conforme aux procédures d’archéologie préventive. L’Inrap s’est adapté à ces nouvelles exigences, et le travail a été amorcé avec les nouveaux partenaires que sont les gestionnaires des cours d’eau. Dans ce contexte particulier, le potentiel archéologique reste mal évalué dans l’ensemble, et son atteinte mal mesurée. L’expérience de Nouvelle-Aquitaine relève d’une longue pratique en archéologie programmée et d’une organisation nouvelle incluant des personnels formés pour les interventions de terrain, du matériel et le recours à la détection sonar et à la géomatique.

Published: August 2023

Créé en 1830, le musée des Beaux-arts et d’Archéologie de Troyes accueille les découvertes archéologiques locales, puis le mobilier issu des premières fouilles entreprises dans l’Aube. Il s’efforce depuis de présenter le résultat des opérations récentes, telles les plus belles découvertes issues des fouilles réalisées dans les années 1980 et 1990 (autoroute A5, transformations de l’urbanisme troyen, domus dite de Chaillouet) notamment par l’Association pour les fouilles archéologiques nationales (Afan). Ce sera toujours le cas dans le nouveau parcours lié à la réfection du musée. Ainsi, la tombe princière de Lavau, étudiée par l’Inrap, sera l’un des points d’orgue de ces salles archéologiques rénovées. Les salles archéologiques des musées se doivent de synthétiser les savoirs autour des ensembles mobiliers jugés représentatifs d’un moment de l’histoire proche ou lointaine dont nous sommes héritiers. Et cela ne peut se faire sans l’expertise évidente des chercheurs de la communauté archéologique.

Parkinson's disease (PD) is a multisystem disorder considered the second most common neurodegenerative disease worldwide of which neuroprotective therapies are not yet available. PD is known mainly by its cardinal motor symptoms which are believed to be associated with dopamine deficiency in the nigrostriatal pathway as a result of DAergic neurons degeneration in the substantia nigra pars compacta of the midbrain. However, other brain structures degenerate (non-dopaminergic abnormalities) in PD resulting in other symptoms known as non-motor symptoms (NMS). NMS and non-DAergic abnormalities are sometimes present before diagnosis and almost inevitably emerge with the disease progression. Hence, they might play a tremendously important role in the management and sometimes even the diagnosis of PD. This chapter will provide an overview on the neuropathobiology of NMS in PD.

Published: August 2023

Parkinson's disease is known by tremor, rigidity, and bradykinesia. Non-motor symptoms also manifest during the disease course or even predate the appearance of motor-symptoms and that can be as troublesome as motor features. At the cellular level, the degeneration of substantia nigra neurons and the low levels of dopamine caused by intracytoplasmic inclusions of Lewy bodies that consist of α-synuclein were recognized as the putative cause of the disease and therefore physical symptoms. PD is a slow-moving illness and detection of that disease is not easy because of delayed symptoms, variation in clinical manifestations, course of progression, and biomarker profiles from person to person. Early diagnosis of PD plays a critical role in effective disease management. Here, the authors aim to give an overview of different methods of diagnosing PD with emphasis on clinical differential diagnosis that differentiate it from other parkinsonian disorders, challenges, and a brief description of new approaches of artificial intelligence technologies as a tool for better prediction of that disease.

Published: August 2023

In the past two decades, the use of various materials for various structural and mechanical aspects has become increasingly important. Scientists in today's high-tech world have a vested interest in exotic materials with novel features. Composite material utilisation has increased dramatically during the past two decades to satisfy the needs of the aerospace, nuclear, and aeronautics industries. Fibre reinforced polymer matrix composites are increasingly being used in place of traditional metallic materials due to their superior performance in a number of areas, including fatigue, damage tolerance, and greater resistance to oxidation. In this investigation, the authors set out to develop and characterise a polymer-based composite packed with nano-micro particles for use in aerospace. In this chapter, the authors employ a hybrid of the FAHP and FTOPSIS to assign an overall rating to various dental composites. The research results presented here enhance the development of effective and precise damage detection techniques for composite materials.

In order to find the glaucoma in an early stage with the help of optical coherence tomography (OCT) using deep learning and extracting the features of glaucoma, the authors are able to classify the four types of glaucoma such as CNV, DME, DRUSEN, and the normal ones with perfect accuracy by training this dataset. This dataset contained 968 images and 242 images of each type the authors trained their model by using CNN algorithm, and has greater accuracy of when compared to the determination of glaucoma using support vector machine image. The authors have good architecture constructed for the determination. They pre-trained their deep learning model in order to obtain the initial representation. The proposed system gives out 95.4% accuracy level of sensitivity, specificity, and classification. A large increase in the volume of the cup, a larger cup diameter, and a thickened lip of the neuroretina rim suggest glaucoma. These regions correspond anatomically to currently used clinical markers for glaucoma diagnosis.

Published: August 2023

The primary form of transportation is roads. But because of the high volume of traffic on the roads and other environmental conditions, regular maintenance is required. This maintenance is frequently neglected as it is impossible to watch over every location, or just out of ignorance. Potholes are created as a result, which increases traffic and increases the likelihood of accidents. However, there are many methods/systems available which can be used to detect potholes using various image processing methods. The accuracy of these systems is highly affected in rainy weather. In this chapter, a system is designed to detect pothole during rainy season effectively. This system also collects the location of potholes, which can be further provided to authorities for maintenance work. The proposed system can be used for driverless cars.

Malaysia's digital gap index is a measure of disparities in internet access and utilization. The west Malaysian region has witnessed growth, but emotional intelligence and internet usage continue to present obstacles. To close the divide between those who have access to digital technologies and those who do not, the government must emphasize individual education. The implementation of 5G technology in Malaysia has the potential to reduce the digital divide and promote inclusiveness, thereby contributing to the growth of a sustainable and environmentally conscious economy. In east Malaysia, the implementation of sustainable development practices, community empowerment initiatives, and 5G infrastructure has the potential to reduce disparities and promote economic growth, ecological preservation, and social well-being. By providing equitable opportunities and promoting innovative economic and environmental progress, the government can effectively tap into the innovative potential and vitality of east Malaysians.

Published: August 2023

Public investment into the availability of ICT infrastructure has been studied for decades to assess its effect on economic development and productivity growth. Whereas in the 1980s, this referred to the effects of telephones, since the 1990s it is the availability of internet connections, which is of great interest for politicians and policy makers alike. During the Covid-19 pandemic, social distancing has led to a transformation of work relations and the widespread introduction of work from home. Also, distance education as well as the increased importance of online streaming portals for leisure activities proved the necessity for fast broadband coverage and adoption. The authors investigate the degree of broadband coverage with a special focus on Austria and provide a survey on the economic benefits especially of high-speed internet connections for the economic development. The authors show to which extent Austria is using the full potential of fast and ultrafast internet connections and highlight the benefits for both firms and inhabitants in both rural and urban environments.

Anomaly detection on sequence dataset typically focuses on the detection of collective anomalies, aiming to find anomalous patterns consisting of sequences of data with specific relationships rather than individual observations. In this survey, existing studies are summarized to align with temporal sequence dataset and spatial sequence dataset. For the first category, the detection can be subdivided into symbolic dataset based and time series dataset based, which include similarity, probabilistic, and trend approaches. For the second category, it can be subdivided into homogeneous datasets based heterogeneous datasets based, which include multi-dataset fusion and joint approaches. Compared to the state-of-the-art survey papers, the contribution of this paper lies in providing a deep analysis of various representations of collective anomaly in different application field and their corresponding detection methods, representative techniques. As a result, practitioners can receive some guidance for selecting the most suitable methods for their particular case.

The Table Tennis game does not involve large displacements by the practitioner in the environment, a characteristic that can promote greater safety for the elderly in locomotor terms. In addition, it needs coordination, agility, speed of reaction, dynamic balance, which have been the focus of current recommendations of physical activity for the health of adults and the elderly. The aim of this study is to investigate the effects of table tennis practice on physical and functional fitness in the elderly. This quasi-experimental research with a parallel and controlled design. The sample consisted of 16 elderly people, allocated 8 in the experimental group (EG) and 8 in the control group (CG). The research lasted 18 weeks, with 2 weeks of evaluation (initial and final) and 16 weeks of intervention. Physical fitness assessments were carried out using the agility and balance and functional fitness tests. In the intra-group comparison (pre-post intervention), EG showed a significant difference for the variable agility (pre: 15.6 ± 1.2 s; post: 14.7 ± 0.7 s). Also, the EG showed a reduction in Area (pre: 11.00±3.32 cm2; post:  6.52±3.06 cm2), AP Amplitude (pre: 4.92±2.77 cm; post:  3.28±0.58 cm) and ML speed (pre: 2.77±1.07 cm/s; post:  2.31±1.03 cm/s) in the Tandem posture with eyes open. Our findings highlight the importance of a Table Tennis program, administered twice a week and consisted of low to moderate intensity activities, to promote a beneficial effect on the agility and balance of physically active elderly people.
Genome-wide markers show continental structuring and mitonuclear discordance in the forest tent caterpillar (Malacosoma disstria Hübner) (Lepidoptera: Lasiocampidae)
Authors: Roe Amanda D. , MacDonald Zachary G. , Snape Kyle L. , Sperling Felix A.H.
Published: August 2023

The forest tent caterpillar, Malacosoma disstria Hübner (Lepidoptera: Lasiocampidae), is an irruptive forest pest found throughout North America. Widespread species such as M. disstria are exposed to historical and contemporary processes that are not uniform and can generate regionally distinct genomic variation. Previous analyses used a short mitochondrial fragment to infer broad-scale phylogeographic patterns in M. disstria, whereas nuclear markers have been previously applied only in a smaller geographic region. In this study, we quantified M. disstria population variation with genome-wide single nucleotide polymorphisms and cytochrome c oxidase from mitochondrial DNA. Using highly variable genome-wide markers, we resolved clear genomic differences among populations of M. disstria east of the Rocky Mountains that were not detected using mitochondrial variation alone. We also did not detect host-associated divergence in either our genomic or mitochondrial data. Our results highlight the utility of genome-wide markers to resolve intraspecific population structure within a widespread species and support the need for further biogeographic sampling of this forest insect pest.
Green infrastructure planning based on ecosystem services multicriteria evaluation: the case of the metropolitan wine landscapes of Bordeaux
Authors: Calia Giovanna , Serra Vittorio , Ledda Antonio , De Montis Andrea
Published: August 2023

Excessive anthropogenic activities affect landscape patterns and trigger a decrease of natural capital and the level of quality of life. Green infrastructures (GIs) are commonly accepted by scholars as solutions for restoring degraded areas and providing a variety of ecosystem services (ESs). The other way around, the capacity to deliver ESs can be assumed as a relevant starting point for GIs analysis and planning. The assessment of ESs needs extensive investigation and applications, to provide planners, policy makers, and institutional stakeholders with an adequate evaluation tool. The multi-facet nature of ESs assessment implies the use of complex tools able to consider many concerns. In this regard, multicriteria analysis (MCA) is a very popular tool due to its capacity to intertwine a variety of issues in a rigorous way and to support participatory and transparent decision making in the public domain. In this study, we aim at contributing to the integration of GI design into spatial planning starting from the assessment of the net benefit delivered to local society by a GI in the metropolitan area of Bordeaux (France). We assessed the net benefit by confronting the ESs deliverable by the GI and the cost sustained for its construction and maintenance. We applied an MCA-based method to the selection of the most efficient alternative out of three GI paths. We demonstrate that our method is useful for the assessment of cultural and regulating ESs, comparing the GI design alternatives, and considering the preference model of the stakeholders within GI planning and design.
Hyperspectral imaging system to on-line monitoring the soy flour content in a functional pasta

Published: August 2023

Pasta enriched with soy flour can be considered as a functional food, due to its content in nutraceutical compounds such as isoflavones, carotenoids, and other antioxidants. The quantification of the amount of a functional ingredient is an important step in food authenticity. The availability of non-destructive techniques for quantitative and qualitative analyses of food is therefore desirable. This research was aimed to investigate the feasibility of hyperspectral imaging in reflectance mode for the evaluation of the soy flour content, also to investigate on the possibility to implement a feed-back control system to precisely dose the soy flour during the industrial production of pasta. Samples of pasta in shape of spaghetti were produced with durum wheat semolina and soy flour at increasing percentages (0, to 50%, steps of 5%). A feature selection algorithm was used to predict the amount of soy flour. The most influent wavelengths were selected, and a six-term Gauss function was trained, validated, and tested. The identified transfer function was able to predict the percentage of soy flour with high accuracy, with an R2adj value of 0.98 and RMSE 1.31. The developed system could represent a feasible tool to control the process in a continuous mode.

Background: The International Severe Acute Respiratory and Emerging Infections Consortium (ISARIC) 4C mortality score has been used before as a valuable tool for predicting mortality in COVID-19 patients. We aimed to address the utility of the 4C score in a well-defined Saudi population with COVID-19 admitted to a large tertiary referral hospital in Saudi Arabia.  Methods: A retrospective study was conducted that included all adult COVID‑19 patients admitted to the Armed Forces Hospital Southern Region (AFHSR), between January 2021 and September 2022. The receiver operating characteristic (ROC) curve depicted the diagnostic performance of the 4C Score for mortality prediction.Results: A total of 1,853 patients were enrolled. The ROC curve of the 4C score had an area under the curve of 0.73 (95% CI: 0.702-0.758), p<0.001. The sensitivity and specificity with scores >8 were 80% and 58%, respectively, the positive and negative predictive values were 28% and 93%, respectively. Three hundred and sixteen (17.1%), 638 (34.4%), 814 (43.9%), and 85 (4.6%) patients had low, intermediate, high, and very high values, respectively. There were significant differences between survivors and non-survivors with regard to all variables used in the calculation of the 4C score. Multivariable logistic regression analysis revealed that all components of the 4C score, except gender and O2 saturation, were independent significant predictors of mortality.Conclusions: Our data support previous international and Saudi studies that the 4C mortality score is a reliable tool with good sensitivity and specificity in the mortality prediction of COVID-19 patients. All components of the 4C score, except gender and O2 saturation, were independent significant predictors of mortality. Within the 4C score, odds ratios increased proportionately with an increase in the score value. Future multi-center prospective studies are warranted.

A revised qualitative assessment of the hydrocarbon resource potential is presented for the Hudson Bay sedimentary basin that underlies Hudson Bay and adjacent onshore areas of Ontario, Manitoba, and Nunavut. The Hudson Basin is a large intracratonic sedimentary
basin that preserves dominantly Ordovician to Devonian aged limestone and evaporite strata. Maximum preserved sediment thickness is about 2.5 km. Source rock is the petroleum system element that has the lowest chance of success; the potential source rock is thin, may be discontinuous, and the thin
sedimentary cover may not have been sufficient to achieve the temperatures required to generate and expel oil from a source rock over much of the basin. The highest potential is in the center of the basin, where the hydrocarbon potential is considered mp;lt;'Mediummp;gt;'. Hydrocarbon potential
decreases towards the edges of the basin due to fewer plays being present, and thinner strata reduce the chance of oil generation and expulsion. Quantitative hydrocarbon assessment considers seven plays. Input parameters for field size and field density (per unit area) are based on analog Michigan,
Williston, and Illinois intracratonic sedimentary basins that are about the same age and that had similar depositional settings to Hudson Basin. Basin-wide play and local prospect chances of success were assigned based on local geological conditions in Hudson Bay. Each of the seven plays were
analyzed in Rose and Associates PlayRA software, which performs a Monte Carlo simulation using the local chance of success matrix and field size and prospect numbers estimated from analog basins. Hudson sedimentary basin has a mean estimate of 67.3 million recoverable barrels of oil equivalent and a
10% chance of having 202.2 or more million barrels of recoverable oil equivalent. The mean chance for the largest expected pool is about 15 million recoverable barrels of oil equivalent (MMBOE), and there is only a 10% chance of there being a field larger than 23.2 MMBOE recoverable. The
small expected field sizes are based on the large analog data set from Michigan, Williston and Illinois basins, and are due to the geological conditions that create the traps. The small size of the largest expected field, the low chance of exploration success, and the small overall resource make it
unlikely that there are any economically recoverable hydrocarbons in the Hudson Basin in the foreseeable future. The Southampton Island area of interest includes 93 087 km2 of nearshore waters around Southampton Island and Chesterfield Inlet in the Kivalliq Region of Nunavut. Of the total resource
estimated for Hudson Bay, 14 million barrels are apportioned to the Southampton Island Area of Interest.

Published: August 2023

Background

The most common kind of liver cancer, hepatocellular carcinoma (HCC), is the fourth leading cause of cancer-related mortality worldwide and has poor prognosis. Strong hepatocarcinogen diethyl nitrosamine (DENA) is a well-known substance. It is well known that DENA damages DNA repair enzymes and is typically used to cause liver cancer in experimental animal models, such as rats. Cerastes cerastes L-amino acid oxidase (Cc-LAAO) has hepatoprotective, antioxidant, and anticancer effects.

Objective

To assess the effectiveness of L-amino acid oxidase (LAAO) as a hepatoprotective agent in comparison to paclitaxel (PAC) as a conventional anticancer medicine in the early identification of HCC using biomarkers [alpha-fetoprotein (AFP) and carcinoembryonic antigen (CEA)], various liver function tests, and oxidant and antioxidant tests.

Materials and methods

CCl4 (200 mg/kg b.wt.) was injected subcutaneously once a week for 3 weeks after a single IP dose of DENA (200 mg/kg b.wt.) to develop hepatocellular cancer in rats. Twenty-five adult, mature, healthy rats were used in this investigation; their average weight was 100±10 g, and they were divided into five groups, each with five rats. After the experiment, some hepatic tests, histology of the liver, a tumor biomarker, and some kidney functions were assessed for all groups.

Results and conclusion

ASAT, ALAT, ALP, total bilirubin, tumor markers AFP, CEA, and lipid peroxides malondialdehyde (MDA) significantly rose in serum after DENA administration in rats, whereas activating antioxidants like SOD, CAT, GPx, and GSH decreased. LAAO and paclitaxel significantly ameliorated biomarkers for liver damage, lipid peroxides (MDA), antioxidants such as (SOD), (CAT), (GSH), (GPx), tumor marker (AFP), and (CEA) compared with the HCC group. Histopathology showed vacuolar hepatocytes with dispersed hepatocyte necrosis and infiltration of mononuclear cells. When used with DENA, the LAAO administration reduced negative effects and produced positive effects. These findings demonstrate that LAAO prevents liver HCC caused by DEN by preventing lipid peroxidation, hepatic cell oxidative stress, and boosting the antioxidant system.

Published: August 2023

Background

Prunella vulgaris L. is a perennial herb belonging to the Lamiaceae family, it is used as antibacterial, antipyretic, antiseptic, antispasmodic, astringent, carminative, diuretic, febrifuge, hypotensive, stomachic, septic, tonic, vermifuge, and vulnerary properties are all seen to be alternatives to whole plants. Potassium is an important macronutrient for plants because of its ability to affect meristem development, water status, photosynthesis, long-distance assimilation of nutrients, enhancement of some enzyme functions, and regulate ionic equilibrium.

Objective

To investigate the effects of various potassium fertilizer applications and the quantity of additions on the growth, production, and some chemical constituents of the P. vulgaris plant.

Materials and methods

Prunella plants were cultivated at SEKEM Company Farm, Belbes, Sharkia, using a drip irrigation system during the two successive seasons of 2018/2019 and 2019/2020 to study the impact of application of different potassium doses (20, 40, and 60 U) and number of added portions (each dose added once or divided into two or three portions) on plant diameter, fresh and dry weight of herb (g/plant and ton/ha), and fresh and dry weight of flowering clusters at both seasons. Photosynthetic pigments in leaves (mg/g fresh leaves), total phenols (mg/g dry herb and flowering clusters), and antioxidant activity (%) in herb and flowering clusters and nitrogen, phosphorus, and potassium concentrations (%) were determined.

Results and conclusion

Increasing units of potassium fertilization from 20 to 60 U gave the highest plant diameter, fresh and dry weight of herb, and fresh and dry weight of flowering clusters. It also led to an intensification of total phenolics, antioxidant activity %, chlorophyll content, and N, P, and K percentages of all Prunella herbs, whether it was added at two or three portions.
Comparative evaluation of conventional versus modified lip repositioning surgery for gummy smile: A Two-year follow-up study
Authors: Puri Sneha , Shewale Akhilesh
Published: August 2023

Background and Aim:

Excessive gingival display can be managed by a variety of treatment modalities, depending on the specific diagnosis. Lip repositioning surgery is a largely unknown and underutilized treatment modality for excessive gingival display. The aim of the present study was to minimize gingival display by comparing the modified lip repositioning procedure with the conventional lip repositioning procedure.

Materials and Method:

A total of 12 patients with gummy smile were selected for the study. The patients were randomly divided into two groups (group A and group B), consisting of six patients each. Group A patients were treated with conventional lip repositioning procedure and group B patients were treated with modified lip repositioning procedure.

Result:

The procedure resulted in a narrower vestibule and restricted muscle pull, thereby reducing gingival display during smiling.

Conclusion:

The lip repositioning technique that was meant to decrease the amount of gingival display proved to be more conservative and provided good aesthetic outcome.
Aspiration of lipoma: Effective use of liposuction
Authors: Dodani Jessica , Goyal Nilesh N
Published: August 2023

Lipomas tend to be surgically excised leaving big scars which often are not liked by patients. Liposuction offers an alternative solution especially for large lipomas, wherein complete resolution can occur with hardly any complications and above all minimal scar at wound site.
