THE ROLE OF INFLUENCERS AND OPINION FORMERS MARKETING ON CREATIVE BRAND COMMUNICATION
Authors: Černikovaitė Miglė Eleonora , Karazijienė Žaneta
Published: June 2023

The growing power of social media and the fast change of communication forms encourages marketers to explore new ways for brands to communicate creatively and effectively. The aim of this study is to determine how to reveal the involvement of influencers in creative forms of brand communication by analysing (comparatively) the expression of Lithuanian and foreign influencers in social networks. Research methodology and results: analysis academic literature and quantitative content analysis in social networks. Literature analysis reviled, that the main dimensions of communication strategy with influencers involves four stages: setting the objectives of the campaign; setting the criteria to find out right influencer; setting campaign duration and platform; influencer performance analysis. The results of the study showed that one of the most important and most inclusive step is choosing the right influencer. It is important to choose not only based on brand profile, but also to evaluate the potential risks when working with one or another influencer. Brands are recommended to choose those influencers that are not overloaded with another brands,integrate advertising into video format and reveal that their integration is brand advertising, because consumers tend to choose the products or services which are chosen by the celebrities they follow.

We describe the discovery of a solar neighborhood (d = 468 pc) binary system with a main-sequence sunlike star and a massive noninteracting black hole candidate. The spectral energy distribution of the visible star is described by a single stellar model. We derive stellar parameters from a high signal-to-noise Magellan/MIKE spectrum, classifying the star as a main-sequence star with T

⊙. The spectrum shows no indication of a second luminous component. To determine the spectroscopic orbit of the binary, we measured the radial velocities of this system with the Automated Planet Finder, Magellan, and Keck over four months. We show that the velocity data are consistent with the Gaia astrometric orbit and provide independent evidence for a massive dark companion. From a combined fit of our spectroscopic data and the astrometry, we derive a companion mass of

These conclusions are independent of El-Badry et al., who recently reported the discovery of the same system. A joint fit to all available data yields a comparable period solution but a lower companion mass of

A Data-driven, Physics-based Transport Model of Solar Energetic Particles Accelerated by Coronal Mass Ejection Shocks Propagating through the Solar Coronal and Heliospheric Magnetic Fields

Published: June 2023

In an effort to develop computational tools for predicting radiation hazards from solar energetic particles (SEPs), we have created a data-driven physics-based particle transport model to calculate the injection, acceleration, and propagation of SEPs from coronal mass ejection (CME) shocks traversing through the solar corona and interplanetary magnetic fields. The model runs on an input of corona and heliospheric plasma and magnetic field configuration from a magnetohydrodynamic model driven by solar photospheric magnetic field measurements superposed with observed CME shocks determined from coronagraph images. SEP source particles are injected at the shock using the result of diffusive shock acceleration formulation from a characteristic obliquity-dependent injection from a heated solar wind thermal tail population. With several advanced computation techniques involving stochastic simulation and integration, the model obtains the particle intensity at any location in interplanetary space through the rigorous solution to the time-dependent 5D focus transport equation in the phase space that includes perpendicular diffusion. We apply the model to the 2011 November 3 CME event. The calculation results reproduce multispacecraft SEP observations at Earth and STEREO-B reasonably well without normalization of particle flux. The observations at STEREO-A can be reproduced by rescaling particle energy or modified energy dependence of particle diffusion coefficients. This circumsolar SEP event seen by spacecraft at Earth, STEREO-A, and STEREO-B at widely separated longitudes can be explained by diffusive shock acceleration by a single CME shock with a moderate speed.
The Behavior of Bp He-weak Stars in the Far UV—Paper VI: HD 21699
Authors: Monier Richard
Published: June 2023

The analysis of spectra of the B8 He-weak Si star HD 21699 recorded by the SWP camera on board the International Ultraviolet Explorer in 1987 reveals large amplitude variations of the far-ultraviolet spectral energy distribution over a time interval of about four days in 1987 October. In contrast, the level of the mid-UV flux did not vary between phases of FUV flux maximum and minimum which suggests that changes of the silicon continuous and line opacity play an important role in the variations. The lines of C iv doublet near 1550 Å are stronger and have an extended blue wing at phase of far-UV maximum. The optical brightness recorded by the Fine Error Sensor on board IUE is probably anticorrelated with the FUV flux, reflecting the redistribution of the FUV flux toward longer wavelengths.

Characterization of two new Pylorgus mitogenomes (Hemiptera, Lygaeidae, Ischnorhynchinae) and a mitochondrial phylogeny of Lygaeoidea
Authors: Gao Cuiqing , Dong Wen
Published: June 2023

Lygaeidae is a large family of Hemiptera (Heteroptera) currently separated into three subfamilies, Ischnorhynchinae, Lygaeinae, and Orsillinae. In this research, the complete mitogenomes of the iscnorhynchines Pylorgus porrectus Zheng, Zou & Hsiao, 1979 and Pylorgus sordidus Zheng, Zou & Hsiao, 1979 were sequenced, and the phylogeny of Pylorgus and the Lygaeidae with known complete mitogenomes were examined. The mitogenomes are 15,174 bp and 15,399 bp in size, respectively, and comprised of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and a control region (D-loop). Nucleotide composition is biased toward A and T, and the gene order is identical to that of the putative ancestral arrangement of insects. Eleven PCGs begin with a typical ATN, and the remaining two PCGs begin with TTG (cox1 and nad4l). All tRNAs had a typical cloverleaf secondary structure, but some of them had individual base mismatches. The phylogenetic analyses based on the concatenated nucleotide sequences of the 13 PCGs, using Bayesian inference and maximum likelihood, support the monophyly of Lygaeidae. The results show that P. porrectus and P. sordidus clustered with nine other Lygaeidae. This study includes the first complete sequencing of the mitochondrial genomes of two Pylorgus species, which will provide important data for studying the phylogenetic position of Lygaeidae in Lygaeoidea and reconstructing the phylogenetic relationships within Pentatomomorpha.
Le jeu de rôle : une médiation thérapeutique. Propositions conceptuelles sur les caractéristiques malléables du « JdR » en psychothérapie d’adolescents
Authors: Boulay Corentin , Pascal Roman
Published: June 2023

Les psychothérapies d’enfants et d’adolescents, notamment les psychothérapies à médiations, recourent à la fois aux activités de jeu et créatrices pour favoriser l’émergence de la symbolisation. Le jeu de rôle est une forme de jeu inédite, au confluent des approches ludiques et narratives, relativement peu étudiées à l’heure actuelle dans le champ psychodynamique. Néanmoins, il dispose de propriétés créatrices singulières qui articulent le travail de créativité groupal, la formation de narratifs et de récits, l’interactivité avec le cadre fictionnel, narratif et ludique. Ainsi, un travail de conceptualisation, articulant théorie psychanalytique, approche ludologique et narratologique, peut permettre de circonscrire les caractéristiques médium-malléable du Jeu de rôle, favorisant son inscription dans une prespective thérapeutique.
Un « marchandage » maussien ? L’accumulation par le don dans l’économie numérique
Authors: Fourcade Marion , Kluttz Daniel N.
Published: June 2023

La collecte de données sur les personnes, les organisations et les choses et leur transformation en une forme de capital est souvent décrite comme un processus d’« accumulation par dépossession », une perte généralisée de droits renforcée par des pratiques prédatrices et la violence juridique. Pourtant, cet argument ne cadre pas avec le fait que l’inscription dans les systèmes numériques est souvent vécue (et présentée par les entreprises) comme un processus beaucoup plus bénin : s’inscrire à un service « gratuit », répondre à l’invitation d’un « ami » ou être encouragé à « partager » du contenu. Dans cet article, nous nous concentrons sur le rôle central du don et de la réciprocité dans le modèle commercial et l’imaginaire culturel du capitalisme numérique. Nous suggérons que la relation économique qui se développe à la suite d’une offre de cadeau numérique ne masque pas seulement l’asymétrie structurelle entre le donneur et le receveur, mais permet également la création d’une nouvelle marchandise, les données personnelles, obscurcit sa véritable valeur et naturalise son appropriation privée. Nous appelons ce régime unique « l’accumulation par le don ».

Détruire les communs environnementaux ou dépasser le système-monde ? Pour un matérialisme du mouvement
Authors: Cadalen Pierre-Yves
Published: June 2023

Le présent article défend une approche matérialiste des dynamiques de transformation de l’Anthropocène à partir d’une rencontre entre le concept de communs environnementaux et la théorie du système-monde. L’écopouvoir est défini par l’auteur comme pouvoir de réunir les conditions de disparition ou de perpétuation de l’espèce humaine et de larges pans du vivant. La rencontre théorique proposée par cet article entend nourrir les discussions quant aux changements qualitatifs possibles et nécessaires du système-monde compte tenu de la destruction en cours des communs environnementaux.
L’associatisme médiéval au-delà des enclosures. À l’origine des communs, des collectivités territoriales et de l’ESS
Authors: Draperi Jean-François
Published: June 2023

Les communs sont définis ici comme des groupements de personnes s’engageant volontairement et solidairement dans le gouvernement de biens. On distingue deux ensembles de communs médiévaux : les communs d’habitants et les communs de métiers. Ils sont, pour l’essentiel, reconnus juridiquement, édifient un mode économique et instituent un mode de vie. Ces traits expliquent qu’ils aient en partie survécu aux enclosures. Nous définissons les communs d’habitants au Moyen Âge (1) avant de montrer leur actualité à travers deux exemples, la vallée du Queyras et la Confédération suisse (2). Nous présentons ensuite les communs de métiers (3), et exposons les liens entre ces communs et l’économie sociale et solidaire contemporaine. Cette inscription dans la durée permet de définir le concept l’associatisme.
Désenclaver l’histoire des Communs de l’histoire de l’État des Modernes. Associations syndicales de propriétaires entre « droit social » et « domestication administrative »
Authors: Ingold Alice
Published: June 2023

Le sort des Associations syndicales invite à écrire une autre histoire de la tension entre pluralité sociale et pouvoir centralisé à la charnière entre XIX e et XX e siècles. Le devenir de ces associations syndicales après 1789 interroge très directement la manière dont le collectif a été pensé après la Révolution. Je montre comment Maurice Hauriou, dans son célèbre commentaire de l’arrêt pour l’Association syndicale du canal de Gignac, en 1899, ne peut concevoir ces syndicats hors d’un monde binaire opposant collectif et public, économique et politique. Trente ans plus tard, Georges Gurvitch voit dans ces mêmes associations syndicales l’expression d’un « droit social » spontané, issu donc de la créativité normative de la société, mais « annexé par l’État ». Ce jugement de Gurvitch est formulé en 1932, au terme donc d’une évolution de ces structures syndicales qui aurait confirmé leur « domestication administrative » – annoncée par Hauriou en 1899. Mes recherches montrent que ces organisations collectives n’ont pas tant été des institutions « hybrides », à la frontière du public et du privé, pour reprendre les termes d’Hauriou, que des organisations collectives qui ne se laissent précisément pas enfermer dans cette partition binaire, soit du côté de la logique privée contractuelle, soit du côté d’un droit public. Ces institutions ont précisément bousculé ce partage en train d’être consolidé par l’ordre étatique entre privé et public, dans une partition binaire où l’État s’est accaparé la capacité à dire le plus qu’un. J’appelle à désenclaver l’histoire de ces communs en restituant l’historicité de l’avènement de l’État des Modernes, qui a précisément sommé ces dispositifs collectifs de basculer soit du côté du civil et du contractuel, soit du côté du public et de l’administratif. Bref, je veux restituer ici l’hétérogénéité d’une vie collective qui ne se réduit ni à la coordination de droit privé, ni au droit public.
Les communs, l’État et le gouvernement de moindre souveraineté
Authors: Sauvêtre Pierre
Published: June 2023

L’article questionne la conception de la relation entre l’État et les communs dans le courant autonomiste marxiste comme un antagonisme entre deux systèmes sociaux, et pose le problème pour les communs de la possibilité d’une relation à l’État qui permettrait l’expansion des communs. Ce problème est mis à l’épreuve des tentatives municipalistes pour développer les communs en s’appuyant sur l’État local. Alors que certaines expériences d’institution des communs (ABC Napoli, chartes des communs urbains de Bologne) sont fragilisées par leur subordination à la souveraineté des pouvoirs publics, d’autres parviennent au contraire par un interventionnisme juridique à instituer un droit à l’autogouvernement des biens publics qui neutralise partiellement l’exercice de sa souveraineté par l’État local. C’est le gouvernement de moindre souveraineté.
Un nouveau paradigme de l’État social
Authors: Blanc Yannick
Published: June 2023

Le social occupe une place importante dans l’agenda du préfet, mais celui-ci est au centre d’un jeu dont il ne peut assurer la cohérence. La capacité de coordination de la fonction préfectorale est largement mythique car, comme le montre l’expérience de Territoires zéro chômeur de longue durée, la cohérence d’une action dans la durée ne dépend pas d’un pouvoir de coordination mais de l’élaboration progressive d’un cadre de coopération stratégique. L’enchevêtrement des administrations sociales est le fruit de la concurrence/combinaison de trois modèles d’action collective (institutionnel, entrepreneurial, coopératif). La situation de crise aiguë des deux premiers place le troisième au cœur d’un nouveau paradigme de l’État social, à condition que celui-ci développe en son sein les compétences nécessaires à l’accompagnement de la coopération stratégique.
Les ARS au milieu du gué
Authors: Laforcade Michel
Published: June 2023

Les ars interviennent dans un contexte particulier. Dans le secteur social et médico-social, comme dans le reste de la société, la polyarchie et donc la balkanisation du pouvoir des acteurs ont tendance à se renforcer. Comme cette réalité s’impose sans blocs de compétences homogènes (du type une seule autorité compétente pour une seule population), l’enchevêtrement des compétences est la règle. Les ars ont pourtant partiellement participé au regroupement des compétences, surtout dans le domaine de la santé. En revanche, l’enchevêtrement subsiste dans les autres secteurs dans lesquels la décentralisation bénéficie d’un statut culturel hégémonique. Pour des raisons politiques et idéologiques, elle est devenue une forme de tabou et de totem à la fois. Peu évaluée scientifiquement, elle s’impose comme étant presque toujours la solution et presque jamais le problème. Des solutions existent toutefois : un retour de l’État qui retrouverait sa capacité à obliger les autres acteurs au partenariat, le retour du social aux ars , la création de blocs de compétences homogènes… Tout cela n’aura de sens que si l’évaluation scientifiques de ces politiques publiques progresse sous le regard et avec l’aide des usagers.
Les CAF dans l’enchevêtrement des acteurs de la politique familiale
Authors: Haurie Jean-Louis
Published: June 2023

La « politique familiale » est une politique complexe par nature car elle recouvre une multitude d’objectifs qui se sont stratifiés au fil du temps, impacte de nombreux domaines et repose sur de nombreux acteurs aux modalités d’intervention diverses. Le jeu d’acteurs qui en découle, au sein duquel l’État joue un rôle prépondérant, est malaisé, nuit à la cohérence et à la lisibilité du système et souvent à son efficacité. Les hésitations entre décentralisation et déconcentration, la libéralisation du secteur des services, les concurrences qui en procèdent amplifient ces errements et impactent les usagers. Cette politique familiale de plus en plus compliquée à mettre en œuvre mêle désormais des intervenants de plus en plus nombreux sans que pour autant sa cohérence soit organisée autour d’un pilote ou d’un chef de file. Émergent dès lors, soit au sein des organisations et des caf en particulier (polyvalence, processus, mutualisation…), soit à l’extérieur (maisons de service public, néo-services publics…), des tentatives d’organisation coordonnées et finalisées. Pour l’essentiel segmentées sur des objectifs précis, ces organisations ne répondent pas aux besoins de proximité, de globalité et de transversalité auxquels devrait s’attacher un vrai service public des familles.
Spatial patterns for a predator-prey system with Beddington-DeAngelis functional response and fractional cross-diffusion
Authors: Xue Pan , Ren Cuiping
Published: June 2023

In this paper, we investigate a predator-prey system with fractional type cross-diffusion incorporating the Beddington-DeAngelis functional response subjected to the homogeneous Neumann boundary condition. First, by using the maximum principle and the Harnack inequality, we establish a priori estimate for the positive stationary solution. Second, we study the non-existence of non-constant positive solutions mainly by employing the energy integral method and the Poincaré inequality. Finally, we discuss the existence of non-constant positive steady states for suitable large self-diffusion $ d_2 $ or cross-diffusion $ d_4 $ by using the Leray-Schauder degree theory, and the results reveal that the diffusion $ d_2 $ and the fractional type cross-diffusion $ d_4 $ can create spatial patterns.

Published: June 2023

Las unidades de experimentación convencional de animal pequeño son instalaciones complejas de planificar y diseñar. Es por ello que a la hora de diseñar una nueva unidad puede resultar muy valioso recopilar la información que se encuentra disponible sobre unidades similares ya construidas para así poder analizar los diferentes modelos conceptuales y los flujos de trabajo que puedan servir de referencia para su diseño. En este trabajo, a través de expresiones gráficas estandarizadas, se estudia el modelo organizativo y el diseño conceptual de la unidad de experimentación convencional de animal pequeño de tres Institutos de Investigación Sanitaria acreditados por el Instituto de Salud Carlos III. A partir de la puesta en común de los resultados obtenidos del análisis de varios casos, se pueden sacar conclusiones que pueden ser de utilidad en el diseño de fututos centros, tanto para los investigadores como para los profesionales responsables de la programación funcional, diseño, construcción y puesta en funcionamiento de nuevos centros de experimentación convencional de animal pequeño.
Ciudadanía, elecciones y movilización política en Cuba durante el Trienio Liberal (1820-1823)
Authors: Santos Fuentes Alain J.
Published: June 2023

La puesta en marcha del sistema representativo en Cuba durante el Trienio Liberal estuvo marcada por la agitación y la movilización casi permanente de la ciudadanía. Tanto en La Habana como en el resto de poblaciones de la isla, el calendario electoral se vio alterado por sucesivas anulaciones totales o parciales de los resultados, lo cual generó un ambiente de crispación política que inquietó a las élites y autoridades. Este trabajo busca reconstruir ese proceso, casi desconocido por la historiografía, a través de diversas fuentes electorales.
Aether dynamics: Classical mechanics explained
Authors: Atkinson Peter M. , Nlend Samuel
Published: June 2023

In this paper, we propose that the density of the aether is a universal constant and is the same in all inertial frames of reference. We suggest that other physical phenomena, such as the speed of light, Maxwell's equations, and gravity, which are the same in all inertial frames of
reference, behave in this manner, because they all depend on the density of the aether. We discuss the origin of mass in terms of aether displacement by subatomic particles with mass. Explanations of Newton's laws of motion, based on the aether, are given. The fundamental causes of kinetic
energy and momentum are explained in relation to the aether. We offer an explanation for the constant speed of light. Einstein's special theory of relativity is explained in relation to the constancy of the aether density, and the famous equations in his theory are derived using basic aether
dynamics. We suggest that aether particles are fundamental particles behaving like tiny springs as proposed by Hooke's law and be given the name aetheons. We propose the spring constant of the aetheon ultimately limits the speed of light to  c

Complete power cycle exhaust heat regeneration and the second law of thermodynamics
Authors: Van Den Einde David
Published: June 2023

A closed condensing power cycle using tetrafluoromethane or R14 and a solid solute as its working fluid is described. The inclusion of a solid solute that yields a positive excess enthalpy of solution with the R14 creates a potential for complete exhaust heat regeneration. The solution
reaction provides a temporary thermal reservoir for the cycle's low temperature exhaust heat until that energy is regenerated as heat by retrograde solubility during the cycle's high temperature and low density expansion phase. A slow solute dissolution rate in the solvent's low density state
near the cycle's high temperature enables the cycle to utilize all of the regenerated exhaust heat either as work output or by exhausting surplus heat at a second temperature level. The cycle's thermodynamic path establishes solvent property reference points that can be used to determine the
maximum positive excess enthalpies of solution required for a solvent to accomplish total exhaust heat regeneration when used as the cycle's working fluid.
Electrical stimulation in lower motoneuron lesions, from scientific evidence to clinical practice: a successful transition
Authors: Bersch Ines , Mayr Winfried
Published: June 2023

Long pulse stimulation in its application in everyday clinical practice still represents a challenge for many therapists and clinicians. It is often unclear how the intervention setup, in particular the parameters pulse width, frequency and amplitude, can influence muscle morphology. In addition, the cause of damage to the lower motoneuron can have multiple reasons and is not anatomically located at the same site. Given the large heterogeneity, it is essential to know the current options and limitations in order to carry out a targeted treatment. A retrospective data analysis of n=128 patients, seen at the Swiss Paraplegic Centre (SPC) in 2022, shows a broad variability in manifestation of lower motoneuron damage. Treatment examples based on different causes of lower motoneuron damage are shown and corresponding stimulation programmes are assigned, as well as the expected results in terms of stimulation duration, volume and configuration.
Microplastics in Sepia officinalis caught on the central Adriatic coast: preliminary results
Authors: Armellini Alessia , Ferri Gianluigi , Lauteri Carlotta , De Camillis Antonio , Pennisi Luca
Published: June 2023

Microplastics (µPs) represent an emerging problem for the marine environment given their wide bioavailability for all aquatic organisms, from zooplankton to top predators. This work aimed to evaluate a method of extracting microplastics from the gastrointestinal tract of 122 Sepia officinalis caught from the Adriatic Sea (along Abruzzo region coasts) to measure its quantity in a poorly investigated species. The extraction method used for gastrointestinal content was performed using 10% potassium hydroxide. In 98/122 (80.32-95% CI=73.27-87.37%) wild animals microplastics were detected with a mean concentration of 6.82±5.52 µPs/subject. Among the fragments, as supported by various authors, those of black color were the most represented ones; however, also blue fibers and transparent spheres were isolated. This study, in agreement with previous ones, poses further attention to the wide microplastic diffusion in the marine environment (surface, columns, sediments, and animals). The obtained results provide the basis for future investigations on this public health concern.
The Anxiolytic and Antidepressant Effect of Stachys lavandulifolia in the Experimental Pentylenetetrazole-Induced Rat Model of Acute Seizure
Authors: Azizi Vahid , Allahyari Farzin , Hosseini Abdolkarim
Published: June 2023

Objective

In traditional medicine, Stachys lavandulifolia or mountain tea has been used in the treatment of arthritis and rheumatoid arthritis. A leaf extract from this plant is also thought to be effective in treating epilepsy as well as other neurological ailments. To assess the effect of S. lavandulifolia extract (SLE), rats were exposed to a stress and anxiety model caused by seizures.

Materials and Methods

A challenge dose of pentylenetetrazole (PTZ) (60 mg/kg) was used to induce seizures in male Wistar rats (200–250 g). Animal treated with an intraperitoneal injection of either SLE (50 mg/kg) or sodium valproate (100 mg/kg) alone or in combination 30 min before PTZ challenge. The effect of stress and anxiety was assessed using an open field test (OFT), forced swim test (FST), and elevated plus maze (EPM). At the end of the experiment, anesthesia was used to euthanize rats, and their blood serum was collected for measurements of glutathione (GSH), malondialdehyde (MDA), and GSH peroxidase (GPx).

Results

In contrast to the control group, those treated with PTZ exhibited depressive behavior. At 50 mg/kg, SLE provided protection against seizures induced by PTZ. SLE also reduced seizure-induced stress and anxiety, significantly improving FST, EPM, and OFT compared with the PTZ-treated group. By decreasing MDA levels and restoring the antioxidant enzymes GSH and GPx, SLE treatment protects against seizure-induced anxiety and stress.

Conclusions

SLE inhibits oxidative stress damage and seizure-induced stress by inhibiting seizures’ inhibitory effects.
IBD-Disk as a tool estimating the prevalence of inflammatory bowel disease-related disability and associated influencing factors in Saudi Arabia: A cross-sectional study

Published: June 2023

Background:

Inflammatory bowel disease (IBD) disk is an easy tool to use in clinical practice to measure IBD-related disability, with a score >40 correlating with high daily-life burden. Its use has been limited mainly to the western world. We aimed to estimate the prevalence of IBD-related disability and evaluate the associated risk factors in Saudi Arabia.

Methods:

In this cross sectional study conducted at a tertiary referral center for IBD, the English IBD disk was translated into Arabic, and patients with IBD were approached to complete it. Total IBD disk score (0 = no disability; 100 = severe disability) was documented and a score of >40 was set as a threshold to estimate the prevalence of disability.

Results:

Eighty patients with a mean age of 32.5 ± 11.9 years and disease duration of 6 years, including 57% females, were analyzed. The mean IBD-disk total score was 20.70 ± 18.69. The mean subscores for each function within the disk ranged from 0.38 ± 1.69 for sexual functions to 3.61 ± 3.29 for energy. The overall prevalence of IBD-related disability was 19% (15/80 scoring >40) and was much higher in active disease, in males and in IBD of long duration (39%, 24%, and 26%, respectively). A clinically active disease, high CRP, and high calprotectin were strongly associated with higher disk scores.

Conclusion:

Although the overall mean IBD disk score was low, nearly 19% of our population had high scores signifying a high prevalence of disability. As demonstrated by other studies, active disease and high biomarkers were significantly associated with higher IBD-disk scores.

Irreducible inclusions of simple $C^*$-algebras
Authors: Rørdam Mikael
Published: June 2023

The literature contains interesting examples of inclusions of simple

C^*

-algebras with the property that all intermediate

C^*

-algebras likewise are simple. In this article we take up a systematic study of such inclusions, which we refer to as being

C^*

-
irreducible
by the analogy that all intermediate von Neumann algebras of an inclusion of factors are again factors precisely when the given inclusion is irreducible.

We give an intrinsic characterization of when an inclusion of

C^*

-algebras is

C^*

-irreducible, and use this to revisit known and exhibit new

C^*

-irreducible inclusions arising from groups and dynamical systems. Using a theorem of Popa one can show that an inclusion of II1-factors is

C^*

-irreducible if and only if it is irreducible with finite Jones index. We further show how one can construct

C^*

-irreducible inclusions from inductive limits, and we discuss how the notion of

C^*

-irreducibility behaves under tensor products.

\mathrm{II}_1

subfactor

\oplus_{i\in I} \mathcal{B}(\mathcal K_i)=\mathcal N \subset^{\mathcal E} \mathcal M=\oplus_{j\in J} \mathcal{B}(\mathcal H_j)

For certain generating sets of the subfactor pair

M\subset M\rtimes G

where

G

is a finite abelian group we prove an approximate inequality between their non-microstates free entropy dimension, resembling the Schreier formula for ranks of finite index subgroups of free groups. As an application, we give bounds on free entropy dimension of generating sets of crossed products of the form

M\rtimes(\mathbb{Z}/2\mathbb{Z})^{\oplus\infty}

Published: June 2023

Milk is an essential component of human and animal diets, and cattle are a major source of milk for human consumption. Environmental, nutritional, genetic, and physiological factors can affect animal milk composition. This study was aimed at evaluating the antioxidant properties of milk samples from four cattle breeds, namely: White Fulani (WF), Sokoto Gudali (SG), Red Bororo (RB), and the exotic Holstein Friesian (HF) in Sokoto, Nigeria. Fatty acid, amino acid profile, antioxidant vitamins, antioxidant minerals, and antioxidant enzymes activities of the samples were assessed using standard methods. The results of the analysis indicated that milk of SG had the highest values for moisture (85.57%), Vit C (79.24mg/dl), DPPH scavenging activity (80.04%), and FRAP (1083.33mgTE/100g of FW). Milk of RB had the highest ash (4.52%), protein (3.63%), copper (0.19 ppm), zinc (0.16 ppm), iron (3.47 ppm), and antioxidant amino acid composition. The milk of HF had the highest lipid (5.89%), oleic acid (1.17 mg/ml), total polyphenol content (TPC) (0.26 mgTE/100g of FW) and selenium (103.10 ppm) levels. WF had the highest carbohydrate (15.07%), palmitic acid (98.39 mg/ml), stearic acid (35.46 mg/ml), Vit A (55.38 mg/dl), Vit E (52.18 mg/dl) content, catalase (0.02 U/L) and superoxide dismutase (3.00 U/mL) activities. These results show that milk from the WF has better antioxidants and therefore antioxidant capacities than the other breeds. Overall, the study indicates that cow milk is a good source of antioxidants, whose levels vary between the different breeds of cattle. These nutritional differences can be explored during milk sourcing based on nutritional requirements.

Published: June 2023

Cadmium Sulphide thin films have been successfully electrodeposited on a conducting Indium-Tin-Oxide (ITO) glass substrate, with different deposition time (10 min, 20 min, and 30 min). The Scanning electron microscopy (SEM), UV-Vis spectrophotometry, X-ray diffraction (XRD), and Atomic force microscopy (AFM) were used to characterize the morphological of films obtained. Moreover, Mott–Schottky (MS) measurements and Photoelectrochemical (PEC) measurements were carried out to study their structural, optical and electrical properties respectively. XRD result points to high crystallinity oriented along (002) planes. The studies reveal that the optical transmission increases with decreasing time of deposition. Mott-Schottky and Photoelectrochemical studies indicates that the CdS thin films display n-type semiconductor, which allows used as layer in photovoltaic cell applications.
Implementation of risk-sharing agreements in Saudi Arabia: Comparison and reflection on the NICE Model
Authors: Abu-Shraie Nada , Alhammad Ali , Balkhi Bander , Al-Jedai Ahmed
Published: June 2023

In recent years, healthcare spending has increased, due to factors such as aging population, lifestylebased diseases, and high-cost health technologies. These factors have put enormous pressure on policymakers to curtail costs and shift towards value-based healthcare system. In this system, drug companies must demonstrate the value of their products in real-world settings. However, evidence may not be available at the time of product launch,  leading to delays in reimbursement decisions and access of patients to products. To address this gap, risk-sharing agreements (RSA) have been  introduced between manufacturers and payers. The most common type of RSA is the financial-based agreement which may take various forms such as  annual sales caps, price-volume agreements, and comparator rebates. These agreements allow for rapid access to innovative medications. Another type  of RSA is the outcome-based agreement which ties reimbursement to the real-world outcomes of products. These agreements are more complex, but  they are expected to grow rapidly with the availability of real-world data. In the Middle East, the use of RSA is limited, although it is expected to increase  with the ongoing shift towards a value-based healthcare system and introduction of health technology assessment. Saudi Arabia is leading these efforts  in the region. This study was aimed at describing the current status of RSAs, trends in utilization of RSAs, and challenges of RSA implementation in Saudi  Arabia (KSA). Real-world examples of RSAs in various healthcare sectors are also provided. Overall, the use of RSA facilitates access to innovative  medications while ensuring value for money and efficient utilization of limited healthcare resources
Quyu Xiaozhong recipe exerts anti-inflammatory effect in acute mastitis by inhibiting TLR4/NF-κB signal pathway
Authors: Wang Mingzheng , Jin Li
Published: June 2023

Purpose: To investigate the effect of Quyu Xiaozhong recipe (QYXZR) on acute mastitis induced by Staphylococcus aureus in rats via TLR4/NF-κB signal pathway.

Methods: The rat model of acute mastitis was constructed by injecting Staphylococcus aureus into the fourth pair of nipples of rats 5-7 days after  parturition. The rats were treated with drugs 12 h after injection. Pathological changes in rat mammary tissue were determined using hematoxylin-eosin  (H&E) staining. Myeloperoxidase (MPO) kit was used to evaluate MPO activity. Enzyme-linked immunosorbent assay (ELISA) was employed to determine  the levels of inflammatory factors, while changes in protein expression of TLR4, NF-κB-p65, and IκB-α were determined by Western blot.

Results: QYXZR  intervention significantly attenuated pathological damage in rats and alleviated Staphylococcus aureus-induced mastitis. At the same time, QYXZR  significantly reduced the expression of MPO and the levels of inflammatory factors (p < 0.05). Further molecular mechanistic studies revealed that QYXZR  exerted anti-inflammatory effects by inhibiting TLR4/NF-κB signal pathway.

Conclusion: QYXZR alleviates acute mastitis caused by Staphylococcus aureus  via the inhibition of TLR4/NF-κB pathway, thus, providing the scientific and theoretical basis for the extensive use of this traditional Chinese medicine in  the treatment of acute mastitis.

Tabakalar şeklinde gelişim gösteren gruplar sosyal, ekonomik, siyasal ve kültürel anlamda farklılıklar göstermesine karşın ortak bir amaç edinme, grup şeklinde hareket etme, kaynakların belirlenmesi ve bunların en etkili şekilde hedeflere yönlendirilmesi noktasında birleşmişlerdir. Aksi şekilde hareket ise öznenin ihtiyaçlarının karşılanması noktasında kargaşa ve belirsizlik ortamına sebebiyet vereceğinden, amaçlı faaliyetlerde mutabakatın sağlanması işbirliğinin temelini oluşturmuştur. Bu bağlamda bireylerin ekonomik, sosyal, siyasal ve kültürel ihtiyaçlarını karşılamak için oluşturdukları örgütlü grupların sahip olduğu fiziki ve zihni kaynakların kullanılmasında “yönetim” kavramı doğmuştur. Yönetim; evrimsel gelişim ve değişim sürdüren bir olgu olarak değerlendirildiğinde incelenmesi gereken daha birçok yönünü karmaşık ve dinamik yapısında barındırmaktadır. Fen bilimleri ile karşılaştırıldığında daha yeni ve farklı paradigmalara sahip sosyal bilimler evreni; etkileme-etkilenme döngüsünde dokunduğu yönetim biliminde bilim/sanat ikilemini oluşturmuştur. Yönetimin sanat tarafı, kadim zamanlardan bilimsel yönetim dönemine kadar geçen süre içerisinde sezgilerin, geleneksel yönetim anlayışlarının, deneme-yanılma yolu ile var olduğunu ifade etmektedir. Yönetimin bilimsel yönü ise yönetim olgusunun bilimsel yöntemler ışığında ve analitik pozitivist yaklaşımları benimseyen bir bilim olarak icra edilmesi gerekliliğini ortaya koymaktadır. Bu çalışmada sanatsal yönden ele alındığı değerlendirilen Maverdi’nin Yönetimin Esasları adlı eserinin, yönetim kadrajından bir kesit sunularak tanıtılması amaçlanmıştır.
