Introduction - Territoire(s) et Numérique
Authors: Genre-Grandpierre Cyrille , Lacour Claude
Published: September 2023

La « révolution numérique » actuelle, en rendant l’information disponible en temps réel et les interactions spatiales et sociales beaucoup moins dépendantes de la distance physique, bouleverse-t-elle réellement la façon de vivre, de produire et de gouverner les territoires, ou ne conduit-elle qu’à un renforcement de tendances déjà anciennes, à l’image du développement du télétravail ou des e-services, et par conséquent à un modeste renouvellement des préoccupations classiques des sciences régionales : création destructrice d’emplois, rationalisation des moyens, inégalités de développement économique, etc. ? Pour les sciences régionales, fondamentalement, la révolution numérique n’est-elle une révolution que pour ce qui concerne les impacts sociétaux et territoriaux actuels, et surtout à venir, liés au développement de l’intelligence artificielle ? Telles sont les questions abordées dans ce texte qui replace la thématique Territoire(s) et Numérique du colloque de 2021 de l’ASRDLF d’Avignon dans une perspective historique.
Documents d’urbanisme et adaptation au changement climatique : éclairage des intentions grâce à la lexicométrie
Authors: Chavez Saray , Molines Nathalie , Chancibault Katia , De Gouvello Bernard
Published: September 2023

Le changement climatique entraîne une augmentation des précipitations et des températures, avec une incidence particulière sur les villes. Ces dernières connaissent une augmentation du ruissellement pluvial et des phénomènes d'îlots de chaleur urbains. Les plans locaux d'urbanisme intercommunaux (PLUi) ont la capacité de véhiculer des leviers d'adaptation au niveau local. Cependant, il n'existe pas de contenu standard pour les PLUi et les collectivités s’interrogent si leurs documents transmettent effectivement leurs intentions d'adaptation. Nous créons une démarche d'analyse de contenu, spécifiquement conçue pour le Projet d’Aménagement et de Développement Durables (PADD), une pièce clé du PLUi, afin de comprendre ses intentions d'adaptation. La première étape de la méthode, consistant en une analyse lexicométrique, a été appliquée au PADD du PLUi de Nantes Métropole. Les résultats montrent les principaux thèmes discursifs à partir desquels il est possible de formuler des inférences sur la posture adaptative de la collectivité nantaise.
La sous-exploitation d’une technologie de l’information intégrée comme forme de résistance des utilisateurs
Authors: Ait-Taleb Nabil , Mani Zied
Published: September 2023

Cette recherche s’intéresse à la sous-exploitation d’une technologie de l’information intégrée, au prisme de la résistance de l’utilisateur. À partir d’une étude longitudinale qualitative dans une grande entreprise pétrolière, elle analyse le processus et le mécanisme de développement de cette forme particulière de résistance dans le cas d’un ERP (Enterprise Resource Planning). En mobilisant le modèle de résistance de Lapointe et Rivard (2005), nos résultats identifient la « sous-exploitation » comme une forme intermédiaire de résistance liée à un processus continu et itératif, particulièrement présente en phase de post-implémentation. De plus, nos résultats identifient trois dimensions de la sous-exploitation (informationnelle, fonctionnelle et individuelle) et soulignent que les conséquences inhérentes à chaque dimension sont susceptibles d’amplifier la résistance des utilisateurs.
Les déterminants de la transformation numérique dans le secteur public : proposition d’une échelle de mesure
Authors: Arbaoui Saifeddine , Jemjami Nadia
Published: September 2023

À l’ère du numérique, les organisations publiques font face à un défi majeur d’adaptation et d’intégration des technologies d’information et de communication dans leur stratégie. A travers le traitement des données recueillies auprès d’un échantillon de 455 fonctionnaires publics des collectivités territoriales au Maroc, nous proposons une échelle de mesure à cinq dimensions sur la capacité d’une organisation publique à réussir sa transformation numérique. Les cinq facteurs du modèle sont : la volonté et le support politiques, l’orientation client-usager ; la simplification des procédures, le développement des compétences des fonctionnaires publics et le changement de la culture du service public.
"Ma production est aussi importante que celle d’un mec bien normal" : construction identitaire d’un entrepreneur handicapé
Authors: Lejealle Catherine , Billion Julien
Published: September 2023

Les personnes en situation de handicap peinent à s’insérer dans le marché du travail. L’entrepreneuriat peut être une solution. Selon la théorie de l’effectuation, l’identité de l’entrepreneur est un moyen mobilisable pour créer l’entreprise. Cette étude montre la place du handicap dans la construction de l’identité professionnelle d’un entrepreneur aveugle. Selon les contextes, l’entrepreneur joue entre visibilité et invisibilité du handicap. Cette flexibilité identitaire constitue une stratégie de coping avec la non-conformité du modèle dominant du mâle blanc et reste acteur de sa destinée. L’étude contribue théoriquement et empiriquement aux champs de l’effectuation et de l’identité au travail.
The Role of Experts in Public Deliberations. A Rawlsian Epistemically Responsible Democracy
Authors: Baccarini Elvio
Published: September 2023

L’objet du présent article est le suivant : comment développer une justification publique en matière de justice qui respecte à la fois le pluralisme entre des citoyens libres et égaux, la qualité épistémique des décisions et la responsabilité épistémique ? Pour aborder ce problème, j’envisage le modèle de justification publique proposé par John Rawls, en particulier sa conception de la légitimité et de la justification des décisions publiques présentes dans sa théorie de la raison publique. J’insiste sur les éléments épistémiques de la doctrine de Rawls concernant la justification publique, en particulier le rapport à la science dans le cadre de la raison publique. Je propose toutefois d’amender la description rawlsienne des raisons scientifiques publiques afin d’inclure un ensemble de raisons plus ancrées dans les besoins du monde réel, à savoir de considérer la légitimité d’un ensemble de conclusions scientifiques raisonnables, en tant que raisons justificatives publiques valides, sans se limiter à des conclusions hors de toute controverse. J’indique le problème que constitue l’attribution de légitimité au pluralisme raisonnable des raisons scientifiques pour une détermination probante des politiques. Ma solution consiste à considérer comme légitimes — parce que raisonnables — des décisions sélectionnées selon une procédure démocratique équitable.

Cet article identifie certains des argument clés justifiant ces réformes, ainsi que les orientations principales qu’elles ont suivies. L’article donne également quelques exemples illustrant la diversité des réactions professionnelles à ces réformes et appelle à analyser finement les relations entre managers et médecins, ainsi que les déterminants des coopérations et des conflits entre les acteurs du système hospitalier.
Activité hospitalière : impact de la pandémie Covid-19, le retard a-t-il été rattrapé ?
Authors: Cash Roland
Published: September 2023

La crise sanitaire liée à la Covid-19 a eu des conséquences importantes sur la prise en charge des autres pathologies, avec des retards de soins, des déprogrammations d’interventions lors des phases de confinement, des patients craignant de venir se faire soigner. Cette situation a créé une sorte de « dette sanitaire » qui n’a pas pu être rattrapée. Et même si l’activité 2022 retrouve les niveaux observés en 2019, cela ne constitue pas un rattrapage. De fait, dans de nombreuses affections, le nombre de séjours reste anormalement bas. Car après la crise sanitaire les établissements de santé subissent une crise des ressources humaines qui freine les reprises d’activité. On peut craindre pour les années à venir une aggravation de la morbi-mortalité dans certaines pathologies, à commencer par la cancérologie.
Multi-class EEG signal classification with statistical binary pattern synergic network for schizophrenia severity diagnosis
Authors: Esther Rani Dr. P. , Pavan B.V.V.S.R.K.K.
Published: September 2023

Electroencephalography (EEG) is a widely used medical procedure that helps to identify abnormalities in brain wave patterns and measures the electrical activity of the brain. The EEG signal comprises different features that need to be distinguished based on a specified property to exhibit recognizable measures and functional components that are then used to evaluate the pattern in the EEG signal. Through extraction, feature loss is minimized with the embedded signal information. Additionally, resources are minimized to compute the vast range of data accurately. It is necessary to minimize the information processing cost and implementation complexity to improve the information compression. Currently, different methods are being implemented for feature extraction in the EEG signal. The existing methods are subjected to different detection schemes that effectively stimulate the brain signal with the interface for medical rehabilitation and diagnosis. Schizophrenia is a mental disorder that affects the individual's reality abnormally. This paper proposes a statistical local binary pattern (SLBP) technique for feature extraction in EEG signals. The proposed SLBP model uses statistical features to compute EEG signal characteristics. Using Local Binary Pattern with proposed SLBP model texture based on a labeling signal with an estimation of the neighborhood in signal with binary search operation. The classification is performed for the earlier-prediction shizophrenia stage, either mild or severe. The analysis is performed considering three classes, i.e., normal, mild, and severe. The simulation results show that the proposed SLBP model achieved a classification accuracy of 98%, which is ~12% higher than the state-of-the-art methods.
Stability of delay Hopfield neural networks with generalized proportional Riemann-Liouville fractional derivative
Authors: Agarwal Ravi P. , Hristova Snezhana
Published: September 2023

The general delay Hopfield neural network is studied. It is considered the case of time-varying delay, continuously distributed delays, time varying coefficients and a special type of a Riemann-Liouville fractional derivative (GPRLFD) with an exponential kernel. The presence of delays and GPRLFD in the model require two special types of initial conditions. The applied GPRLFD also required a special definition of the equilibrium of the model. A constant equilibrium of the model is defined. We use Razumikhin method and Lyapunov functions to study stability properties of the equilibrium of the model. We apply Lyapunov functions defined by absolute values as well as quadratic Lyapunov functions. We prove some comparison results for Lyapunov function connected deeply with the applied GPRLFD and use them to obtain exponential bounds of the solutions. These bounds are satisfied for intervals excluding the initial time. Also, the convergence of any solution of the model to the equilibrium at infinity is proved. An example illustrating the importance of our theoretical results is also included.
Key protein identification by integrating protein complex information and multi-biological features
Authors: Han Yongyin , Liu Maolin , Wang Zhixiao
Published: September 2023

Identifying key proteins based on protein-protein interaction networks has emerged as a prominent area of research in bioinformatics. However, current methods exhibit certain limitations, such as the omission of subcellular localization information and the disregard for the impact of topological structure noise on the reliability of key protein identification. Moreover, the influence of proteins outside a complex but interacting with proteins inside the complex on complex participation tends to be overlooked. Addressing these shortcomings, this paper presents a novel method for key protein identification that integrates protein complex information with multiple biological features. This approach offers a comprehensive evaluation of protein importance by considering subcellular localization centrality, topological centrality weighted by gene ontology (GO) similarity and complex participation centrality. Experimental results, including traditional statistical metrics, jackknife methodology metric and key protein overlap or difference, demonstrate that the proposed method not only achieves higher accuracy in identifying key proteins compared to nine classical methods but also exhibits robustness across diverse protein-protein interaction networks.
Le Fragmentum Pragense (Národní Knihovna, VII A 16/9) de Tite-Live
Authors: Russo Adriano
Published: September 2023

Cet article est consacré à un fragment manuscrit de la Bibliothèque nationale de Prague (VII A 16/9) transmettant des portions du livre III des Ab Urbe condita de Tite-Live. La première partie analyse le fragment dans ses aspects paléographiques et codicologiques et reconstruit virtuellement la physionomie originaire du volume. La deuxième partie retrace son histoire. Le manuscrit provient de l’entourage du duc de Naples Jean III (928-968) et peut être comparé à d’autres livres de sa bibliothèque, dont la dispersion semble avoir été assez précoce. Avant le XVe siècle, le manuscrit fut démembré et partiellement transféré en Allemagne. Deux bifolia furent réemployés à Erfurt dans la reliure d’un incunable qui appartint un siècle plus tard à un bibliophile silésien, et qui a été acquis en 1625 par la bibliothèque des Jésuites à Prague. Cet épisode de translation du manuscrit livien de Naples vers l’Allemagne est, dans la troisième partie, placé dans le cadre plus large des phénomènes de migration des livres en écriture bénéventaine de l’Italie du Sud vers les bibliothèques allemandes.
Cyberbullying
Authors: Ravi Sharad Shandhi
Published: September 2023

Children and teens often use the internet today. Because kids and teens are using the internet more frequently, a new kind of bullying (harassment) called cyberbullying has emerged. The schoolyard is no longer a place where harassment is accepted. Cyberbullying is the term used to describe harassment that takes place online. Cyberbullying has commonly been described as a “extreme, deliberate activity or action carried out by an individual or a group utilising electronic forms of contact, repeatedly and over time against a victim who cannot quickly defend himself or herself.” In addition to mail, pictures, messages, smartphones, internet, and social media sites, bullying may also happen through other avenues. A 22-year-old girl in Kerala, India, who was a famous TikToker, supported the Kerala minister's approaches towards cyberbullying. Only because of that has she been continuously bullied by her followers. The followers used bad commends and threatened her by saying she will be raped by them. Impact of cyberbullying, preventive measures, and law support are discussed here.
Applications of Artificial Intelligence in IoT

Published: September 2023

Artificial intelligence is an excellent solution for handling big data streams and storage in IoT networks. The IoT is becoming more significant with the discovery of high-speed internet networks and lots of superior sensors that may be incorporated into microcontrollers. Internet information streams will now consist of sensor record and user data sent and obtained from workstations. As the range of workstations and sensors keep growing, some information may face reminiscence, latency, channel boundaries, and network congestion problems. Within the last decade, many algorithms were proposed to avoid some of these issues. Amongst all algorithms, AI stays the best solution for data mining, network control, and congestion management.
Redox Reactions for Chemical Oxygen Demand in the Light of Health, Environmental Protection, and Technical Practicability
Authors: Kolb Marit , Bahadir Müfit
Published: September 2023

Determination of the important wastewater parameter chemical oxygen demand (COD) in international standard procedures is still based on the use of mercury sulfate and potassium dichromate, which are hazardous to health and the environment (REACH). In order to overcome this environmental paradox, alternative oxidizing agents were compared, and a new wet-chemical method using Mn(III) as an oxidant was developed that works without Cr(VI) and Hg(II). Oxidation of potassium hydrogen phthalate as a reference substance was reproducible in a COD range of 20–500 mg/L with a mean recovery of 88.7% compared with the standard Cr(VI)-method. A high correlation (R2 = 0.9935) to the standard Cr(VI)-method with a mean recovery of 78.1% (± 5.2%) was found for a series of industrial and municipal wastewater samples. Although the results of the new method were not 100% of the standard method, its high correlation with the latter and its reproducibility offer an environmentally benign alternative wet chemical method.

Authors: Krishnamoorthy Sivakumar , Thanigaivel Poongodi
Published: September 2023

Plate-like cadmium sulfide (CdS) quantum dots were prepared by using β-cyclodextrin as reductants. Photoluminescence and UV-Visible diffused reflectance spectroscopic techniques are used to investigate the optical property of CdS. The blue-shifted emission of CdS at 469nm than the bulk particle is observed. The calculated band gap of the CdS quantum dot is 2.62 eV showing a difference of 0.2 eV energy greater than that of bulk, indicating the quantum size effect. The synthesized quantum dot has a size in the range of 3.5nm with a zinc blend crystallite structure. The plate-like nanoclusters of CdS are inferred from SEM images. The photocatalytic efficiency of prepared CdS was tested for the degradation of rhodamine B dye using natural solar light. The effect of the weight of the catalyst, concentration of dye, pH of the solution, and reusability of the catalyst were investigated. The existence of isosbestic point observation of a high intense absorbance peak at 550nm at 300min in different matrix circumstances confirms the formation of leuco Rh B.

Published: September 2023

One strategic area in research and development is to promote innovation for economic development and technology transfer. In a knowledge-based economy, innovation is omnipresent, and its significance is never disputed. Tanzania is aware that information and communication technology (ICT) is the major enabler of socio-economic growth; hence, it needs more ICT innovations, which has shown a slow growth due to many challenges. ICT innovation has significantly impacted private sectors compared to public sectors. The main challenge is mainly in public sectors and individuals. The study explores ICT innovation challenges towards effective participation in innovation actors. The methodology includes a systematic literature review and the primary data collected from the case study area on Tanzania's public and private sectors. The study revealed that though funding and capital to Innovation factors are the major challenges, more challenges have been explored. The study comes up with best practices to persuade ICT innovation participation from the grassroots to the university.

Published: September 2023

Technical and secure information on the production of quality atemoya seedlings (Annona squamosa L. x Annona cherimola Mill.) are of paramount importance due to the growing interest in this crop. This study aimed to assess the formation of atemoya seedlings propagated by grafting methods and cultivars using araticum (Annona sylvatica) rootstocks. The experiment was carried out in a screened environment at the Western Paraná State University (Unioeste), Campus of Marechal Cândido Rondon, Paraná State, Brazil. Atemoya grafts (Thompson, African Pride, and Gefner) were collected from plants from the CATI seedling nursery, located in São Bento do Sapucaí, São Paulo State, Brazil. Grafting was performed using 1-year-old araticum rootstocks with 8–10 mm in diameter at a height of 15 cm from the ground and grafts measuring, on average, 8.5 cm in length, 10 mm in diameter, and three buds. The experimental design consisted of randomized blocks in a 3 × 3 factorial arrangement (three grafting methods: cleft graft, whip and tongue graft, and chip budding × three cultivars: African Pride, Thompson, and Gefner), with four replications and 10 seedlings per replication, totaling 40 seedlings per treatment. The percentage of graft success (%), percentage of sprouting (%), number of sprouts, number of leaves, and longest sprout length (cm) were assessed at 60 days after grafting. The cleft graft method is efficient for producing atemoya seedlings. The cultivar African Pride can be grafted onto rootstocks by the cleft graft and whip and tongue graft methods, as they promote a higher percentage of graft success. The Annona sylvatica rootstock has potential for the production of atemoya seedlings, but chip budding is not viable.

Black spot (Asperisporium caricae) is one of the main foliar fungal diseases of papaya crops. This disease acts directly on leaves and fruits causing leaf area reduction and fruit deterioration. The quantification of diseases is a fundamental part of the disease management and control process; therefore, a scale is required to help quantify black spot disease. The objective of this work was to propose a standardized methodology to quantify black spot severity in papaya leaves. A scale was developed considering the maximum and minimum values of the disease in the field that included eight levels of severity: 0.1, 0.3, 0.6, 1.0, 2.3, 5.0, 10.0, and 20.0%. Without the aid of a scale the disease is often overestimated, with absolute errors of approximately 75%. When the scale was used, 100% of the evaluators showed improved accuracy and precision, and absolute error was reduced to the 10% range. The scale also provided good repeatability and high reproducibility. The use of the scale provided an improvement in the R2 values, with mean values of 93 and 92 in the second and third evaluations, respectively, demonstrating that the scale is useful for different aspects of the pathosystem of A. caricae, such as for determining the efficiency of fungicides, characterization of varietal resistance, construction of the disease progression curve, and estimation of damage.

Published: September 2023

Waterlogging directly interferes with the production capacity of agricultural crops in response to the morphophysiological changes caused to plants. Since the cultivation of poorly drained soils is traditionally avoided, this study aimed to evaluate the possibility of expanding canola cultivation into waterlogged soils using soil surface drainage and different row spacings in lowland areas of Rio Grande do Sul, Brazil. Treatments consisted of the presence and absence of surface drains at 0.25 m depth and row spacings of 0.17, 0.34, 0.51, and 0.68 m arranged in two-factorial randomized blocks with four replications, in 2018 and 2019. In this study, growth traits, yield components, and the final grain yield of canola were evaluated. The increase in lateral branching in canola plants was found to be directly related to waterlogging and negatively affected yield. The use of drains positively impacted the number of pods per plant, seeds per pod, the 1,000 seeds weight, and grain yield. The more intense waterlogging conditions in 2018 resulted in the highest grain yield and superior production traits were obtained with row spacings between 0.41 and 0.48 m. In the absence of waterlogging, the 0.17 m row spacing was more productive. Canola cultivation can occur in waterlogged soils in the presence of surface drainage and at row spacings ranging from 0.40 to 0.50 m.

Published: September 2023

The development of superior cultivars involves parents with superiority for the traits of interest and wide genetic variability. Efficient plant breeding and selection strategies that allow for the identification of superior genotypes are essential in breeding programs. This work aims to carry out a comparative study between several strategies for choosing parents, for hybridization purposes, based on phenotypic analysis and molecular information. To obtain the phenotypic and genotypic information of the parents, data simulation was used. For genotyping, 2000 single nucleotide polymorphism markers were used, and from all possible gametes to be formed (22000), 5000 were randomly sampled to form each of the 100 individuals of the population of recombinant inbred strains. To obtain the phenotypic information, five characteristics with different levels of complexity were simulated. The comparative study was carried out using data referring to simulated genotypic values of hybrids and parents. Then, aiming to choose the parents destined for hybridization, different traditional selection strategies based on phenotypic analysis and the genome-wide selection methodology were approached. The genomic information resulted in the choice of the best lines and in obtaining superior hybrids when compared with traditional methodologies. The inclusion of the genomic genetic values of the parents in determining the crosses to be carried out increases the probability of generating phenotypically superior hybrids. Thus, the traditional methods of choosing parents for hybridization purposes are effective, but when incorporating the information from genome-wide selection, the choice of parents provides superior and promising results.

Published: September 2023

Multi-trait multi-environment (MTME) models were fitted to eucalyptus breeding trials data to assess residual variance structure, genetic stability and adaptability. To do so, 215 eucalyptus clones were evaluated in a randomized complete block design with 30 replicates and one plant per plot in four environments. At 36 months of age, tree diameter at breast height (DBH) and pilodyn penetration (PP) were measured. Two MTME models were fitted, for which residuals were considered homoscedastic and heteroscedastic, with the best MTME model selected using Bayesian information criterion. The harmonic mean of the relative performance of the genotypic values (HMRPGV) was used to determine stability and adaptability. Of the two models, the heteroscedastic MTME model had better fit and provided greater accuracy. In addition, genotype-by-environment interaction was complex, and there was low genetic correlation between DBH and PP. Rank correlation between the clones selected by the MTME models was high for DBH but low for PP. The HMRPGV facilitated clone selection through simultaneous evaluation of stability, adaptability, and productivity. Thus, our results suggest that heteroscedastic MTME model / HMRPGV can be efficiently applied in the genetic evaluation and selection of eucalyptus clones.

The objective was to evaluate the quality of Japanese quail eggs stored at room temperature (26.8ºC) and under refrigeration (10.9ºC), for different storage periods (0; 5; 10; 15; 20; 25 and 30 days). A total of 196 quail eggs were assigned to different treatments in a factorial arrangement of 2 (temperatures) x 7 (storage periods), with 3 replications and 4 eggs per experimental unit. Data were subjected to regression analysis of parameters as a function of storage time at room temperature and under refrigeration. There was a reduction in egg weight, albumen weight and height, yolk height and egg yolk index with increasing storage period as a function of temperatures (p < 0.05). Eggs at room temperature showed a reduction in albumen index, while eggs under refrigeration showed a quadratic behavior (p < 0.05). Storage days promoted a quadratic response in albumen and yolk pH (p < 0.05) of eggs at room temperature. Eggs at room temperature floated from the 15th day of storage. When stored at room temperature, quail eggs show a sharp decrease in internal quality during storage for up to 30 days. Refrigerated storage is recommended.

The objective of this research was to identify the influence of the evaporative adiabatic cooling system (EACS) on the thermal comfort and productive responses of dairy cattle, through multivariate analysis by principal components (PC), in the summer and winter seasons of the semiarid region of Pernambuco, Brazil. The data came from an experiment that included 16 multiparous lactating cows (7/8 Holstein-Gyr), randomly distributed in 4 sets, with 4 experimental phases and 4 treatments (0, 10, 20, and 30 min.). The multivariate analysis was carried out through PC for the thermal comfort indices, physiological variables, and milk production and composition. The highest milk production in the summer season was obtained for animals exposed to the cooling system for 30 min. In the winter season in the morning period, the use of the EACS for 10 min. was sufficient for improvements in milk production. The times of exposure to EACS caused changes in the composition of milk, for both seasons. Principal component analysis made it possible to verify a positive correlation of evaporative cooling with thermal comfort, physiological responses, and production and composition of milk of lactating cows.

Published: September 2023

An experiment was conducted to investigate the effects of graded levels of concentrate on feed intake, biological performance and carcass characteristics of yearling Gumuz sheep. The sheep were purchased and treated against endo- and ecto- parasites before commencing the study. The experimental animals were offered natural grass hay as a basal ration. The experimental design was a Randomized Complete Block Design (RCBD) with six replications. Treatment feeds were arranged in the same amount of wheat bran but in different levels of sesame seed cake which comprises: 150 g wheat bran + 0 g sesame seed cake DM day-1 (T1), 150 g wheat bran + 250 g sesame seed cake DM day-1 (T2), 150 g wheat bran + 350 g sesame seed cake DM day-1 (T3) and 150 g wheat bran + 450 g sesame seed cake DM day-1 (T4). The experiment was conducted for 90 days after 15 days of adaptation period to the experimental feeds and conditions, which were then followed by carcass evaluation at the end. Sheep in T2 and T4 achieved higher total DM intake (1004.03-1072.57 g day-1) than T1 and T3. Sheep fed on graded-level sesame cake supplements (T2, T3 and T4) recorded significantly higher average daily gain (ADG) than the control (T1) and resulted in higher feed conversion efficiency (FCE). As a result of better slaughter weight (SW) achieved significant hot carcass weight (HCW) was recorded in sheep at T3 and T4. Among the concentrate levels, T2, T3 and T4 were found optimum in improving carcass yield and major meat quality attributes. Sheep supplemented with T3 had the highest net return (26.66 USD) and highest marginal rate of revenue (MRR) (6.53) compared to the other high-level sesame cake-supplemented groups. Thus, it is recommended that the supplementation of hay with high-level sesame cake supplement (T3) is biologically efficient and potentially profitable in the feeding of growing Gumuz sheep.

Published: September 2023

This study aimed to propose and compare metrics of accuracy and bias of genomic prediction of breeding values for traits with censored data. Genotypic and censored-phenotypic information were simulated for four traits with QTL heritability and polygenic heritability, respectively: C1: 0.07-0.07, C2: 0.07-0.00, C3: 0.27-0.27, and C4: 0.27-0.00. Genomic breeding values were predicted using the Mixed Cox and Truncated Normal models. The accuracy of the models was estimated based on the Pearson (PC), maximal (MC), and Pearson correlation for censored data (PCC) while the genomic bias was calculated via simple linear regression (SLR) and Tobit (TB). MC and PCC were statistically superior to PC for the trait C3 with 10 and 40% censored information, for 70% censorship, PCC yielded better results than MC and PC. For the other traits, the proposed measures were superior or statistically equal to the PC. The coefficients associated with the marginal effects (TB) presented estimates close to those obtained for the SLR method, while the coefficient related to the latent variable showed almost unchanged pattern with the increase in censorship in most cases. From a statistical point of view, the use of methodologies for censored data should be prioritized, even for low censoring percentages.

Postpartum Family Planning (PPFP) enables women to achieve healthy intervals between births, potentially averting maternal deaths and reducing child mortality. The PPIUD enables women to leave the birth facility with a safe, effective, long-acting, reversible method already in place.The aim of the study was to study clinical outcomes and client perceptions on follow-up after insertion of PPIUD from 2014 to 2019 at the Teaching Hospital, Mahamodara (THM), Galle, Sri Lanka.Results: A total of 46,815 deliveries were reported in the facility during the study period, and 470 (3.4%) PPIUD insertions were carried out. Only 67/470 (14.3%) women who had PPIUD responded to the survey. The median (IQR) duration of PPIUD in situ was 63 (39 - 76) months, and it was positively correlated with the satisfaction score (Spearman’s rho 0.29, p=0.02). Out of all, 58 (86.6%) women recommended PPIUD to a friend as a PPFP method. Median (IQR) satisfaction score for the PPIUD was 9.5 (5.5 - 9.5), and most women (65.7%) were satisfied with PPIUD. However, 19.4% of women responded as ‘Neutral’ to the questionnaire. There were no uterine perforations or ectopic pregnancies.Conclusions: The study shows that PPIUD is a good option as an effective contraceptive method before leaving the birth facility.

Spinal anesthesia is the gold standard anesthetic technique for cesarean section. However, its major complication is hypotension. Norepinephrine has recently been described as an efficient and safe alternative to Phenylephrine. The aim of this study was to determine the effective target bolus of Norepinephrine to prevent and treat post-spinal anesthesia hypotension. We conducted a prospective controlled randomized study including 126 parturients scheduled for cesarean delivery under spinal anesthesia. We compared two groups that received a prophylactic bolus of either 1μg/kg or 0.5μg/kg of Norepinephrine without fluid loading. The rescue intravenous bolus of Norepinephrine was half the dose of the prophylactic bolus. The main outcomes were the percentage of decrease in systolic and mean blood pressure. The secondary outcomes included the timing of the first hypotension, duration of hypotension, number of rescue boluses, total Norepinephrine consumption, incidence of hypotension and maternal adverse effects and fetal outcomes. Our primary outcome has shown similarities between groups; delta systolic blood pressure before delivery was 19.4% in group 1µg/kg versus 20.5% in group 0.5µg/kg. Both groups were similar for all secondary outcomes, except that the higher dose of Norepinephrine resulted in more hypertension. Fetal outcomes were similar in both groups. Bolus of 0.5μg/kg followed by rescue doses of 0.25μg/kg of Norepinephrine was efficient in preventing and treating spinal anesthesia-induced hypotension. These doses may be recommended for routine use in healthy parturients.

Purpose:

To assess short-term efficacy of a single injection of brolucizumab in neovascular AMD.

Methods:

This was a multicenter, retrospective chart review of 25 eyes of 25 patients who received a single injection of brolucizumab. Visual acuity (VA) and optical coherence tomography (OCT) features such as central subfield thickness (CSFT), subretinal fluid (SRF), intraretinal fluid, and pigment epithelial detachment (PED) were recorded at baseline, first month, and third month.

Results:

Of the 25 eyes, 14 eyes were treatment-naïve and 11 eyes had received previous injections. VA improved from 0.68 ± 0.59 log MAR at baseline to 0.31 ± 0.43 log MAR at the end of 3 months. SRF height in first and third month was significantly reduced from baseline (P < 0.001). Subretinal hyperreflective material height significantly reduced from baseline (P value 0.008 at first month and 0.01 at third month, respectively). CSFT was 464.16 ± 247.97 microns at baseline and showed a significant reduction in first month (P < 0.001) and third month (P < 0.001). There was a significant reduction of PED height from baseline at both follow-ups. None of the eyes showed a recurrence of fluid at the end of 3 months.

Conclusion:

Our study demonstrated sustained improvement in VA and OCT parameters after a single injection of brolucizumab at 3 months. A longer follow-up may demonstrate even farther effects of a single injection.

Published: September 2023

Purpose:

Refractory periorbital dermatitis has a chronic course with exacerbations leading to discomfort and cosmetic issues, yet characterization of treatment options is limited.

Aims:

The objective was to present comprehensive demographic data and medical management of a series of patients with refractory periorbital dermatitis.

Settings and Design:

Retrospective review identified patients treated at a single institution from January 2010 to August 2020.

Methods:

Descriptive analyses were performed. Demographic data and treatment history were reviewed and data including medication, use, date of use and discontinued use, reason for discontinuation (if applicable), refractory status, formulation, concentration, and dose frequency were extracted.

Statistical Analysis Used:

Descriptive analyses.

Results:

Forty-five patients were included. The average age at first diagnosis was 60.3 years (sd 14.9). 82.2% were women and 84.4% identified as Caucasian. Triamcinolone cream was most frequently used followed by tobramycin–dexamethasone, tacrolimus, and neomycin–polymyxin–dexamethasone. Less than 30% of patients on triamcinolone were refractory. 13.3% of patients used topical hydrocortisone, with over 80% of these patients experiencing refractory episodes of persistent irritation and erythema. Most patients were refractory during initial use or the first recurrence of periorbital dermatitis flare.

Conclusions:

By better characterizing the diverse treatment regimens in a unique subset of refractory patients, we hope to better inform potential courses of medical management for periorbital dermatitis.
Ocular metastasis from renal malignancies – A comprehensive review
Authors: Jindal Akriti , Kapatia Gargi , Gupta Gaurav
Published: September 2023

The most common cause of intraocular mass is metastasis from other tumors. Renal malignancies, though rare, have a substantial number of cases with ocular metastasis, few of which were misdiagnosed. Many a times renal malignancies present with ocular manifestations before the primary diagnosis. Here in this article, we comprehensively reviewed 106 cases of ocular metastasis from renal malignancies published till date to the best of our knowledge. The eye is a rare site for distant metastasis because of the lack of a lymphatic system. The most common ocular structures to get involved in distant metastasis are the uveal tract, i.e., choroid, iris, and ciliary body. The most common renal tumor which metastasizes to eyes is renal cell carcinoma (RCC). RCC accounts for less than 2% of all ophthalmic metastases. Out of total 106 cases, the type of renal malignancy was known in 95 cases only, of which 92 had RCC, 1 Wilm’s tumor, 1 rhabdoid tumor, and 1 medullary carcinoma. The age ranged widely from 2 weeks old to 81 years old. The male to female ratio was 3.4:1. In total, 67.4% of cases had a previous history of RCC, while the rest 32.6% primarily presented with ophthalmic manifestations first. Treatment modalities included enucleation of the eye, debulking surgery followed by radiotherapy and/or chemotherapy and/or immunotherapy.

Published: September 2023

Background:

Currently, vitrectomy is considered as the first line of treatment in the management of macular holes. Various surgical modalities have been described to obtain anatomical closure. However, there are still challenges when the hole is large and chronic (>400 microns) in nature. Here we describe a modified technique of internal limiting membrane (ILM) peeling which results in the successful closure of such macular holes.

Purpose:

To demonstrate modified ILM flap techniques in management of chronic macular holes.

Synopsis:

Here we have described the role of modified ILM peeling techniques in three different cases such as chronic traumatic macular hole >400 microns, chronic idiopathic macular hole >400 microns and <400 microns.

Highlights:

This modified ILM flap technique provides the benefit of an inverted ILM flap, which helps in glial proliferation and also relives tangential traction thereby aiding in successful macular hole closure in chronic cases.
