Le rêve et le perceptif à l’infinitif. De la saturation dans les rêves, les séances et les sciences
Authors: Chervet Bernard
Published: October 2023

Les diverses productions psychiques, depuis les symptômes jusqu’aux formulations scientifiques, peuvent servir à saturer la conscience par la voie endopsychique. C’est ce que fait l’acte de rêver. Pour le dormeur, il n’existe qu’une seule réalité, celle qu’il produit en rêve. Ceci permet d’apporter un ajout à théorie du rêve et de différencier la perception et le perceptif. La perception transmet une réalité qui ne peut donner lieu à des représentations, réalité qui demeure de la perception. Le perceptif est construit à partir d’une autre réalité, celle des représentations. Il tente, par la saturation de la conscience, de dénier la qualité de la perception de ne pas être toute représentable et de produire des effets traumatiques.
Ne croire en rien, croire en tout. Les jeunes et la nébuleuse des croyances contemporaines
Authors: Bibeau Gilles
Published: October 2023

La thèse de l’auteur est que le citoyen démocratique qui a « exilé dieu » s’invente de nouvelles immortalités symboliques à travers des voies spirituelles hybrides et un bricolage des liaisons entre religion, société et politique. Cette résurgence néo-religieuse s’exprime dans des pensées syncrétiques qui mélangent croyance, souci de soi, idéologie du bien-être, utopie de la perfection et projet de transformation du monde. Dans ce ré-enchantement du monde, le religieux surgit à l’interface de la quête de sens individuelle, des conditions quotidiennes et l’espace sociopolitique plus large. La « pensée de l’extrême » s’accompagne souvent, sur un plan psychologique, de sentiments mixtes d’impuissance et d’invulnérabilité qui entraînent des angoisses parfois profondes. L’émergence de cette « pensée de l’extrême » se fait au confluent de trois ordres interreliés de phénomènes qui caractérisent les sociétés contemporaines : 1. l’existence massive des « idéologies de la haine » qui structurent les politiques des États et qui s’infiltrent dans la pensée des personnes individuelles ; 2. La montée de l’agencement sécuritaire du nouvel ordre politique mondial qui prend la forme tantôt de l’état d’exception tantôt du camp ; 3. La réponse symétrique que les « parfaits croyants » – personnes radicalisées, fanatisées – apportent à la violence que nous déployons nous-mêmes contre eux. La genèse des nouvelles formes de psychopathologie doit être envisagée sur ce triple horizon.
Du mal-être contemporain à une clinique des configurations psychiques
Authors: Matot Jean-Paul
Published: October 2023

La première partie de cet article propose une lecture des changements du monde sous-tendant le mal-être contemporain. Une seconde partie expose de manière synthétique les prémisses d’un modèle du fonctionnement psychique conçu comme réseau d’espaces / enveloppes psychiques relevant de niveaux variés d’indifférenciation / différenciation, reliés par des fonctionnements transitionnels spécifiques à chaque passage entre ces espaces. une troisième partie, conclusive, ouvre une perspective analogique entre l’organisation des champs sociaux et cette conception du fonctionnement psychique.
Ce que l’internet fait à l’écriture
Authors: Guichard Éric
Published: October 2023

L’Internet est un système technique qui repose beaucoup sur l’écriture. Il en est même la forme contemporaine. Or l’écriture n’est pas qu’un support de la pensée. Elle l’ informe aussi : l’écriture, par l’intermédiaire des savoir-faire, des méthodes, des réflexions qu’elle induit, dessine les cadres dans lesquels notre pensée peut se déployer : l’ensemble de ces cadres se confond avec notre culture de l’écrit. Aussi l’écriture est-elle définie comme une technologie de l’intellect . L’Internet nous permet de comprendre ce fait déjà connu des historiens et anthropologues de l’écriture : ses réalités matérielles et sociales s’affichent, tout comme les dimensions technique et collective de notre pensée. Comme l’Internet signale une écriture (binaire et réticulée) qui modifie nos systèmes de signes, nos supports, nos méthodes, il modifie aussi l’ensemble de ces cadres. Or peu de personnes maîtrisent cette nouvelle écriture, monopolisée par l’industrie du numérique et aujourd’hui profondément instable. Ces turbulences signalent aussi une capacité d’agir. Si nous choisissons de devenir des lettrés du numérique, nous pouvons devenir acteurs de cette culture numérique à venir et la profiler avec nos valeurs.
« Ceci n’est pas une mère »
Authors: Corcos Maurice

Magritte affirmait que toutes les images sont fausses et voulait « obtenir des images qui résistent à toute explication » . Que d’affirmations de principe et d’autorité a posteriori sur son art, que bon nombre de critiques prennent au pied de la lettre, alors que rien n’est plus évident que le lien direct entre sa pensée, sa peinture et son histoire tragique personnelle et enfin, et surtout les motions pulsionnelles désaffectivées qui alimentent son mystérieux monde interne !
Névrose infantile et névrose de transfert : un inéluctable décalage
Authors: Sirois François
Published: October 2023

L’auteur présente un exemple clinique de reconstruction d’une névrose infantile. Le matériel ainsi apporté permet de questionner la désuétude actuelle de la notion de névrose infantile, et le sort identique de la notion de névrose de transfert aujourd’hui peu utilisée et subsumée sous la question du transfert. Le lien entre les deux formations psychiques est discuté pour souligner leur décalage dans la cure. La notion de névrose infantile a été élargie par Khan et est ici présentée comme le point de consolidation de l’immaturité psychique infantile en lien avec le pouvoir auto-traumatique du développement du moi et de l’instauration de la réflexivité.
La réponse est le malheur de la question. L’apport de Bion au travail du négatif de Green
Authors: Messina Diana
Published: October 2023

Grand auteur de la psychanalyse contemporaine, inscrit dans la filiation freudienne, Green a intégré différentes contributions psychanalytiques pour forger des concepts cliniques incontournables. Il a gardé un souvenir très vibrant des échanges qu’il a eus avec Bion. Nous tentons d’éclairer l’apport de Bion au travail du négatif élaboré par Green. Effacement, hallucination négative, blanc de la pensée, psychose blanche, trous psychiques renvoient à l’impossibilité d’élaborer la frustration, de même qu’à la destruction des capacités de représentation, à l’attaque des liens. La distinction entre absence de l’objet et destruction de l’objet s’inscrivent dans cette réflexion. En toile de fond, quête de sens et vérité apparaissent comme le point nodal commun à la pensée des deux auteurs.
Mélancolie du corps à l’adolescence
Authors: Matha Catherine
Published: October 2023

Il est des situations cliniques où l’excès de souffrance mélancolique destine la pensée à ne pas trouver comment se dire : le texte ne se forme pas. Le corps se propose comme pré-texte, dans le double sens du terme : comme justification à venir à la rencontre (prétexte) et comme texte non encore advenu (pré-texte). Corps-prétexte, exprimant la douleur à défaut de pouvoir la reconnaître, et opérant à l’insu du sujet en défaut de pouvoir affronter ce qui n’est pas identifiable en lui-même. La cure d’une adolescente engagée dans un repli mélancolique et des conduites d’attaque de son corps soutiendra la réflexion.
Le transfert fabrique du signe
Authors: Nassikas Kostas
Published: October 2023

L’auteur suit ici l’exploration de ce qui se joue dans le dispositif analytique à travers l’actualisation transférentielle. Celui-ci devient, selon Freud, une « arène » suite au passage des « rênes du transfert aux pulsions sauvages du patient »  ; une situation clinique nous permet de suivre comment celles-ci cherchent à se satisfaire hallucinatoirement via leurs objets repérés, mais non représentés, dans l’espace psychique de l’analyste. L’autoérotisme du patient, qui s’actualise dans la situation analytique, dote le travail du « transfert » de contenus proches de ceux du rêve, mais plus archaïques : l’hallucination négative du transfert, qui ne dispose pas de représentation mais repère son objet dans l’espace psychique de l’analyste, peut arriver à construire des représentations psychiques si le travail de « traduction » de l’analyste sur les signes binaires et perceptifs du mouvement pulsionnel de satisfaction peut les « coupler » avec des signes ternaires. Ce sont ces nouveaux signes qui permettent la désignation et la nomination des places des absents hallucinatoirement présents dans le dispositif analytique.
Jouer, du clown au psychodrame
Authors: Kammerer Brigitte
Published: October 2023

Une expérience d’atelier à médiation thérapeutique de « clown de théâtre » avec des patients psychotiques, en institution, est l’occasion d’interroger certains aspects du cadre du psychodrame psychanalytique, en particulier, la place qu’y prend le corps. Un aller et retour entre les deux dispositifs met en lumière la dimension infra-verbale qui prend en compte l’appui sur la sensorialité, l’hallucinatoire, la régression, la fonction miroir et la réflexivité.
Identification projective et tridimensionnalité, identification adhésive et bidimensionnalité du psychisme
Authors: Labbé Françoise
Published: October 2023

Dans le registre tridimensionnel du psychisme, Mélanie Klein concepstualise l’identification projective. Bion, à partir de la clinique des états psychotiques, développe l’identification projective normale et pathologique, les attaques contre les liens et la fonction α de la mère. Esther Bick décrit la nécessité d’introjecter un premier objet contenant à défaut de quoi on est dans la bidimensionnalité du psychisme. D. Meltzer et F. Tustin ont étudié l’identification adhésive et les autres mécanismes actifs dans ce registre bidimensionnel caractéristique de l’autisme.
Guérir par l’écriture… ?
Authors: Emmanuel François
Published: October 2023

L’éveil du processus d’écriture peut faire espérer des bénéfices thérapeutiques liés à la mise en mouvement, la mise en jeu, la mise en récit, la distanciation d’un moment traumatique, et la notion de « détachédonné ». Il demeure que l’écrivain, engagé dans une aventure littéraire qui se confond avec sa vie, cherche indéfiniment à se guérir d’une faille originelle par essence inguérissable. Cette faille peut affleurer dans certaines œuvres. À l’écoute de celles-ci il est proposé un parcours depuis Antonin Artaud jusqu’à Jose-Luis Borges en passant par Charles Bertin, Henry Bauchau et Henry James.
Histoire de l’imposture. Journal de création
Authors: Bonté Patrick
Published: October 2023

L’enjeu d’ Histoire de l’imposture est de s’interroger, avec une certaine dose d’humour et d’ironie, sur l’artifice des postures sociales, des jeux de rôles, des normes conformistes qui nous façonnent et nous coulent dans des personnalités d’emprunt, aujourd’hui peut-être plus que jamais. Patrick Bonté est revenu sur la réalisation du spectacle dans un Journal de création où il s’interroge sur le processus lui-même Qu’est-ce qui se dit de l’imposture à travers le spectacle ? Comment un thème s’origine et se fond dans le corps et sur scène ? Mais également sur le sens et les multiples implications de la problématique de l’imposture. L’enjeu d’un tel spectacle est aussi de partager un trouble avec le spectateur. Lui faire dire des choses plutôt que de les exprimer pour lui, comme s’il se trouvait devant un tableau qui délivre des sens multiples, comme s’il avait à faire lui-même le choix du chemin que son regard suit. Être en lien de sensibilité, lui donner la liberté d’être au-delà ou en deçà du réel, alors que tout s’en inspire.

Authors: Berkia Abdelhak , Rebai Billel , Litouche Bilal , Abbas Soufiane , Mansouri Khelifa
Published: October 2023

This research focuses on exploring the free vibration behavior of functionally graded (FG) nano-beams. To calculate the effective properties of the FG nano-beam, which varies solely in the thickness direction, the four homogenization schemes Mori-Tanaka, Tamura, Reuss and Voigt are employed. This study employs high-order shear deformation nano-beam theory and derives the governing equations of motion using nonlocal differential constitutive relations of Eringen. Hamilton's principle is utilized in conjunction with the refined three variables beam theory. The consideration of a length scale parameter accounts for small-scale effects. Analytical solutions are obtained for a simply supported FG nano-beam and compared with existing literature solutions. The research also investigates the influence of different homogenization schemes, the nonlocal parameter, beam aspect ratio and various material compositions on the dynamic response of the FG nano-beam.
Mining association rules between the granulation feasibility and physicochemical properties of aqueous extracts from Chinese herbal medicine in fluidized bed granulation

Published: October 2023

Fluidized bed granulation (FBG) is a widely used granulation technology in the pharmaceutical industry. However, defluidization caused by the formation of large aggregates poses a challenge to FBG, particularly in traditional Chinese medicine (TCM) due to its complex physicochemical properties of aqueous extracts. Therefore, this study aims to identify the complex relationships between physicochemical characteristics and defluidization using data mining methods. Initially, 50 types of TCM were decocted and assessed for their potential influence on defluidization using a set of 11 physical properties and 10 chemical components, utilizing the loss rate as an evaluation index. Subsequently, the random forest (RF) and Apriori algorithms were utilized to uncover intricate association rules among physicochemical characteristics and defluidization. The RF algorithm analysis revealed the top 8 critical factors associated with defluidization. These factors include physical properties like glass transition temperature (Tg) and dynamic surface tension (DST) of DST100ms, DST1000ms, DST10ms and conductivity, in addition to chemical components such as fructose, glucose and protein contents. The results from Apriori algorithm demonstrated that lower Tg and conductivity were associated with an increased risk of defluidization, resulting in a higher loss rate. Moreover, DST100ms, DST1000ms and DST10ms exhibited a contrasting trend in the physical properties Specifically, defluidization probability increases when Tg and conductivity dip below 29.04℃ and 6.21 ms/m respectively, coupled with DST10ms, DST100ms and DST1000ms values exceeding 70.40 mN/m, 66.66 mN/m and 61.58 mN/m, respectively. Moreover, an elevated content of low molecular weight saccharides was associated with a higher occurrence of defluidization, accompanied by an increased loss rate. In contrast, protein content displayed an opposite trend regarding chemical properties. Precisely, the defluidization likelihood amplifies when fructose and glucose contents surpass 20.35 mg/g and 34.05 mg/g respectively, and protein concentration is less than 1.63 mg/g. Finally, evaluation criteria for defluidization were proposed based on these results, which could be used to avoid this situation during the granulation process. This study demonstrated that the RF and Apriori algorithms are effective data mining methods capable of uncovering key factors affecting defluidization.
Optimal secret share distribution in degree splitting communication networks
Authors: Falcón Raúl M. , Aparna Venkitachalam , Mohanapriya Nagaraj
Published: October 2023

Dynamic coloring has recently emerged as a valuable tool to optimize cryptographic protocols based on secret sharing, which enforce data security in communication networks and have significant importance in both online storage and cloud computing. This type of graph labeling enables the dealer to distribute secret shares among the nodes of a communication network so that everybody can recover the secret after a minimum number of rounds of communication. This paper delves into this topic by dealing with the dynamic coloring problem for degree splitting graphs. The topological structure of the latter enables the dealer to avoid dishonesty by adding control nodes that supervise all those participants with a similar influence in the network. More precisely, we solve the dynamic coloring problem for degree splitting graphs of any regular graph. The irregular case is partially solved by establishing a lower bound for the corresponding dynamic chromatic number. As illustrative examples, we solve the dynamic coloring problem for the degree splitting graphs of cycles, cocktail, book, comb, fan, jellyfish, windmill and barbell graphs.
Disciplinary-Based Knowledge Management Systems' Potentialities of Collaborative-Integrative Linkages
Authors: Tetteh Emmanuel N. A.
Published: October 2023

Disciplinary-based knowledge management systems (KMS) shape societal firms, organizations, associations, business enterprises, and social institutions. KMS shaping potency rests in their functional capacities as obligatory mechanisms to provide an ethical sustainability framework for supportive entrepreneurial ecosystems. It is, therefore, imperative to safeguard KMS' instrumentalities of functional capacity against any potential threats to their ethical sustainability frameworks of productive goal attainments. The obligatory mechanisms' outcomes of ethical sustainability frameworks are their catalytic synergies from which KMS collaborative-integrative linkages propel ethical action-learning solutions. These collaborative-integrative linkages are the byproducts of sustainability development, corporate social responsibility, entrepreneurial intention, and values-analysis frameworks. It thus requires providing a modeled ethical case-analytic assessment framework for exploring the obligatory mechanisms of KMS' potentialities to enrich the supportive entrepreneurial ecosystems. This chapter, therefore, introduces students and practitioners to the disciplinary-based KMS obligatory mechanisms that shape ethical sustainability frameworks through collaborative-integrative linkages of the ethical action-learning solutions model for supportive entrepreneurial ecosystems.

Authors: Ke Yinggen , Hemchua Saengchan
Published: October 2023

Cultural differences and geopolitical disputes severely impede the globalization process. As a method of eliminating cross-cultural misunderstandings and fostering mutual respect, it is crucial to increase cross-cultural awareness through cross-cultural education to support the world's peaceful and healthy development. This article investigates, from the perspective of cognitive semiotics, how the integration of digitization and language learning through reading can provide foreign language learners with a more immersive and stimulating learning experience. Questionnaires and interviews demonstrate that digital reading has exerted more significant learning effects on cross-cultural education than traditional paper reading. Digital reading reflects cognitive communication, cognitive subjectivity, and cognitive diversity more accurately. The integration of digital reading and cross-cultural education makes language learning more accessible and effective and can encourage students to grasp the target language while simultaneously promoting Chinese culture.

Authors: Hakim Yusuf Mathiinul , Royani Idha , Mardiyanto Mardiyanto , Mohadi Risfidian
Published: October 2023

The original Java bentonite has been improved by a new method of multi-step impregnation using over-concentrated ammonium under nature temperature. The achieved materials were characterized using SEM-EDX, XRD, FTIR, and BET analysis and then applied in cationic dye adsorption. The specific case in peak XRD analysis of ammonium impregnation was detected at 18°, and the spectra at 532.3 and 470.6 cm-1 of the FTIR analysis were detected as the ammonium vibration and oscillation bending. Surface structure analysis from SEM-EDX showed the smooth and expanded material achieved, supported by surface area analysis of BET, which described the increase of surface area materials from 61.791, 73.089, and 178.710 m2/g for the bent, bent-Na, and bent-NH, respectively. The highest adsorption capacity on bentonite impregnated by ammonium was achieved at 526.316 mg/g and 128.205 mg/g for rhodamine B and malachite green, respectively. The adsorption mechanism was feasible in endothermic and fitted to pseudo-second-order and Langmuir isotherm adsorption model. The new method of ammonium impregnation on bentonite successfully improved the adsorption ability.

Published: October 2023

This paper will present the advantages of developing the 3D printing process of nanomaterials in different fields such as electronics, biomedical and bioelectronics. As it is already known, nanomaterials are starting to become more and more useful, and more emphasis is being put on the development of new technologies to enable the use of these materials. Nanomaterials consist mainly of chemical substances made up from very small particles that are no larger than a hundred nanometers. These materials occur in nature, they can be an accidental product of human activity, or they can be consciously made to develop new characteristics such as strength, chemical reactivity or increased conductivity compared to the same material that does not display nanometric characteristics. By integrating nanomaterials to 3D printing technology, it is possible to create unique structures, which are difficult to achieve. Nanomaterials can possibly work on personal satisfaction and add to the advancement of European industry. However, new materials can also pose health and environmental risks. Scientific research has turned its attention to the potential outcomes of the production and application of nanomaterials. Meanwhile, the newest method for 3D printing of nanomaterials is Multiphase Direct Ink Writing (MDIW), a method developed from Direct Ink Writing (DIW), a revolutionary additive manufacturing mechanism with wide applications in structural engineering systems, thermal isolation, electrical conductivity, optical reflectivity, and biomedical scaffolds.

Authors: Zhou Zhi Kai , Jin Wu Yin , Chen Wen Ke , Wang Shou Rui , Zhang Xia
Published: October 2023

The conventional milling process is difficult due to the high strength and hardness of Cr12MoV, which can cause the rapid tool wear, premature failure,and poor milling quality of work platform. The ultrasonic vibration machining technology has been founded to be effective in the milling process of hard-to-cut materials like die tool steel and nickel alloys. The ultrasonic vibration assisted milling (UVM) technology is carried out the axial milling of Cr12MoV in this paper, and the average impact force Fi is influenced by the vibration amplitude A, the vibration frequency f, and equivalent mass of the vibrating part M. The mean value of cutting force Fx, Fy, and Fz decreases by 25%, 15.04%, and 17.46%, respectively. With the increase of vibration amplitudes, the value of surface roughness firstly decrease and then increase, and it is obviously lower than conventional milling. The experimental results demonstrated that the UVM technology is a feasible method for the low cutting force and high quality process of cutting Cr12MoV.
Cutting Edge: STAT4 Promotes Bhlhe40 Induction to Drive Protective IFN-γ from NK Cells during Viral Infection
Authors: Kim Hyunu , Abbasi Aamna , Sharrock Jessica , Santosa Endi K , Sheppard Sam , Lau Colleen M , Edelson Brian T , Sun Joseph C
Published: October 2023

NK cells represent a cellular component of the mammalian innate immune system, and they mount rapid responses against viral infection, including the secretion of the potent antiviral effector cytokine IFN-γ. Following mouse CMV infection, Bhlhe40 was the most highly induced transcription factor in NK cells among the basic helix-loop-helix family. Bhlhe40 upregulation in NK cells depended upon IL-12 and IL-18 signals, with the promoter of Bhlhe40 enriched for STAT4 and the permissive histone H3K4me3, and with STAT4-deficient NK cells showing an impairment of Bhlhe40 induction and diminished H3K4me3. Transcriptomic and protein analysis of Bhlhe40-deficient NK cells revealed a defect in IFN-γ production during mouse CMV infection, resulting in diminished protective immunity following viral challenge. Finally, we provide evidence that Bhlhe40 directly promotes IFN-γ by binding throughout the Ifng loci in activated NK cells. Thus, our study reveals how STAT4-mediated control of Bhlhe40 drives protective IFN-γ secretion by NK cells during viral infection.

Introduction:

Successful surgical treatment for primary hyperparathyroidism requires accurate localization of abnormal parathyroid tissue in terms of location and number. Imaging is important for localizing the parathyroid adenoma, and there has been significant interest in 18F-fluorocholine (FCH) positron emission tomography/computed tomography (PET/CT) for this purpose.

Aim:

This study attempted to ascertain the utility of 18F-FCH PET/CT as a first-line investigation in preoperative localization of abnormal parathyroid tissue in primary hyperparathyroidism, in comparison with 99mTc-sestamibi dual-phase scintigraphy with early single-photon emission computed tomography (SPECT)/CT and neck ultrasonography.

Materials and Methods:

Fifty-five patients with biochemical features of primary hyperparathyroidism were enrolled in this study. They underwent neck ultrasonography, 99mTc-sestamibi dual-phase scintigraphy with early SPECT/CT, and 18F-FCH PET/CT for localization of parathyroid lesions. Thirty-three patients underwent surgical resection of the detected lesions. For two patients, clinical and biochemical follow-up was used as a gold standard.

Results:

A total of 40 lesions were resected in the 33 patients who underwent surgery. A further two lesions were localized in two patients with clinical and biochemical follow-up as the gold standard. Of these 42 lesions, 41 were detected in preoperative imaging and 1 lesion was noted intraoperatively and resected. 41/42 lesions were detected by 18F-FCH PET/CT (detection rate: 97.6%), 33/42 by 99mTc-sestamibi dual-phase scintigraphy with early SPECT/CT (detection rate: 78.5%), and 30/42 by neck ultrasonography (detection rate: 71.4%).

Conclusion:

Detection rates on 18F-FCH PET/CT were superior to both 99mTc-sestamibi dual-phase scintigraphy with early SPECT/CT and neck ultrasonography in preoperative localization of parathyroid lesions in patients with primary hyperparathyroidism.

Introduction:

Recurrent/persistent primary hyperparathyroidism in patients who have undergone previous parathyroidectomy is a challenging condition. Imaging is important for localizing the parathyroid adenoma for re-exploration and 18F-Fluorocholine (18F-FCH) positron emission tomography/computed tomography (PET/CT) seems ideal for this purpose.

Aim:

This prospective study attempted to ascertain the utility of 18F-FCH PET/CT as an investigation in preoperative localization of abnormal parathyroid tissue in recurrent/persistent primary hyperparathyroidism while comparing it with 99mTc-Sestamibi dual-phase scintigraphy with early single-photon emission CT (SPECT)/CT and neck ultrasonography (USG).

Methods:

Twenty patients with biochemical features of recurrent/persistent primary hyperparathyroidism were enrolled into this study. They underwent neck USG, 99mTc-Sestamibi dual-phase scintigraphy with early SPECT/CT and 18F-FCH PET/CT for localization of parathyroid lesions. Six patients underwent surgical resection of the detected lesions, 3 were awaiting surgery, and 11 were managed conservatively. One patient died due to COVID.

Results:

The calculated positive predictive values on a per-lesion basis of neck USG, 99mTc-sestamibi scintigraphy and early SPECT/CT and 18F-FCH PET/CT in the cohort of the 5 operated patients were 75% (3/4), 71.4% (5/7), and 71.4% (5/7), respectively. On a per-patient basis, the lesion detection rate was 100% for 99mTc-sestamibi scan and FCH PET (5/5) and 80% on neck USG (4/5).

Conclusion:

18F-FCH PET/CT is a highly accurate imaging modality for the detection of parathyroid lesions in patients with recurrent/persistent primary hyperparathyroidism.
Unusual Diffuse and Heterogeneous FDG Uptake in Appendicular Bone Marrow Space in a Patient with Acute Lymphoblastic Leukemia

Evaluating the Environmental Footprint: BPE Framework for Sustainable and Energy-Efficient Residential Buildings in India
Authors: Kasi Jagadeesh , Kaliluthin A K , Kanmani K
Published: October 2023

In the context of enhancing building performance assessment, this study introduces the BPE (Building Performance Evaluation) framework and explores its application through a residential complex in India. An expert evaluation of the questionnaire is carried out to investigate the main element and obstacles to the execution of BPE. The framework, designed to scrutinize five parameters, initially assesses design aspects, including building form, orientation, and aesthetics. Findings reveal that the building design lacks efficient circulation, storage facilities, and satisfactory spatial allocation. Building energy monitoring, essential for comprehensive analysis, faces limitations due to insufficient data availability, emphasizing the need for thorough planning. Thermal comfort analysis, based on temperature and humidity measurements, unveils significant fluctuations beyond comfort thresholds. Expert surveys and occupant feedback further expose reduced utilization of natural ventilation, high air conditioner adoption rates, and adaptive behaviours. The framework's insights prompt opportunities for improvement, yet validation requires broader application across diverse buildings. The study's academic survey emphasizes the importance of integrating BPE in industries with government policies. Field observations highlight challenges in space utilization, material selection, and occupant engagement. This study's findings underscore the BPE-RBPI framework's potential to refine performance assessment, sustainable and energy efficient to foster industry confidence, and drive holistic improvements in India's building sector.

Sentinel satellites make use of Synthetic Aperture Radar (SAR) which produces images with backscattered signals at fine spatial resolution from 10 m to 50 m. This study is mainly focused on evaluating and assessing the accuracy of various supervised classifiers like Random Forest classifier, Minimum Distance to mean classifier, KDTree KNN classifier, and Maximum Likelihood classifier for landuse / landcover mapping in Maduranthakam Taluk, Kancheepuram district, Tamilnadu, India. These classifiers are widely used for classifying the Sentinel SAR images. The SAR images were processed using speckle and terrain correction and converted to backscattered energy. The training datasets for the landcover classes, such as vegetation, waterbodies, settlement, and barren land, were collected from Google Earth images in high-resolution mode. These collected training datasets were given as input for the various classifiers during the classification. The obtained classified output results of various classifiers were analyzed and compared using the overall classification accuracy. The overall accuracy achieved by the Random Forest classifier for the polarization VV and VH was 92.86%, whereas the classified accuracy of various classifiers such as KDTree KNN, Minimum distance to mean, and Maximum Likelihood are found to be 81.68%, 83.17%, and 85.64% respectively. The random forest classifier yields a higher classification accuracy value due to its greater stability in allocating the pixels to the right landuse class. In order to compare and validate the results with sentinel data, the random classifier is applied with optical Landsat-8 satellite data. The classification accuracy obtained for Landsat-8 data is 84.61%. It is clearly proved that the random forest classifier with sentinel data gives the best classification accuracy results due to its high spatial resolution and spectral sensitivity. Thus accurate landuse and landcover mapping promote sustainable development by supporting decision-making at local, regional, and national levels.

In recent decades, MAX phases have attracted considerable attention from the scientific community due to their unique combination of metallic and ceramic properties, which provide exceptional mechanical, thermal, electrical and chemical characteristics. The synthesis of MAX phases in the form of coatings is of increasing interest for many
applications. The aim of this review is to summarize the progress made in the synthesis of coatings based on MAX phases using different methods. The advantages and characteristics of the implementation of ion-plasma physical vapor deposition methods are discussed. The use of ion-plasma methods allows to significantly reduce the synthesis temperature of MAX phases due to the high energy of the particles forming the coating. The effect of deposition parameters on the composition, structure and properties of the coatings is analyzed. Coatings with high protective properties and prospects for their application in industry are considered. This part of the review focuses on methods
for depositing MAX phase based coatings.

Introduction: Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that is widely used to treat pain and inflammation. However, diclofenac use has been associated with a number of side effects, including renal toxicity. The mechanisms underlying diclofenac-induced nephrotoxicity are not fully understood, but oxidative stress and inflammation are thought to play a role. This study investigated the effects of diclofenac on renal antioxidants and cytokines in male Wistar rats. Method: Male Wistar rats were randomly divided into three groups: control group, low and high-dose diclofenac group (10 and 30 mg/kg/day) respectively. Treatment was administered for 10 days. At the end of the study, the rats were sacrificed, serum samples and kidney homogenates were analysed for markers of oxidative stress, lipid peroxidation and inflammation including assessment of renal function. Result: Diclofenac treatment caused a significant decrease in renal antioxidants, including superoxide dismutase (SOD) and glutathione peroxidase (GPx) compared to the control, (0.78±0.11 versus 0.61±0.14), (214.80±46.37versus 149.70±39.43) P <0.05 respectively. In addition, a significant increase in the level of MDA and renal cytokine (TNF-α) was observed between the control and treated group of rats (2.62±0.29 versus 8.74±4.34, p<0.001) and (1276.0±90.18 versus 222.90±38, P=<0.00) and respectively. The high-dose diclofenac caused a significant increase between the treated and control group of rats respectively and deranged renal function test (serum creatinine and renal KIM-1) Conclusion: This study provides evidence that diclofenac may induce alterations in renal antioxidants, and mediates oxidative stress and inflammation with consequent kidney injury in male Wistar rats.

Background: Noma is an infectious disease that rapidly destroys orofacial tissues and neighboring structures in its fulminating course. This study aimed to present a case series of blindness as a result of Noma destruction of the orbital bone and highlight the important aspect of its management. Patients and methods: This was a case series of 12 patients seen and managed for Noma with associated blindness over 2 years study period at Noma Children Hospital Sokoto, Northwest Nigeria. Sociodemographic variables, presenting complaints, presenting visual acuity, investigations, and, the treatment done was recorded. Data were analyzed using IBM SPSS version 25. Result: There were 4 (33.3%) males and, 8 (66.7%) females in the age range of 4-15 years with a mean±SD of 7.5±3.3years. The time range of onset before presentation to our facility was 2 weeks to 4 months. Ophthalmic examination revealed a destroyed globe and purulent discharge with no light perception in all the patients. Anemia and malnutrition were present and, microbiological culture and sensitivity (MCS) yielded no growth in all the patients. Patients were optimized, then later had sequestrectomy and, teeth extraction. Monitoring of patients was done until symptoms resolution. Conclusion: Noma is capable of spreading rapidly to the orbit, causing loss of vision as a complication. However, aggressive medical and surgical intervention in consultation with an ophthalmologist can result in early resolution of symptoms and prevent further spread that may lead to blindness.
Antidiabetic Study of Suaeda Maritima

The genus Suaeda includes widely distributed polymorphic species such as S. maritima, S. calceoliformis, and S. nigra. Much of the variation in these taxa appears to be due to environmental factors, but some of it is probably due to genetic differences. Infraspecific taxa and presumed related species have been described, and these are mentioned in the discussions following the descriptions. However, no infraspecific taxa are recognized here. All three of these species show much variation in morphology and growthform characteristics, but no qualitative characters could be found that could be used to reliably separate distinct taxa below the species level. Future chromosomal and genetic studies may enable the recognition of distinct infraspecific taxa or even species within these three polymorphic entities (FNA,1776).
