Guardian of Image: Evaluating Corporate Reputation as a Shield Against COVID-19 Fallout on Firm Performance
Authors: Aliyah Salsabila Nabilah
Published: June 2024

The COVID-19 pandemic has wreaked havoc on the global economy and posed a significant challenge for companies to survive. This research provides empirical evidence on how the pandemic can adversely affect company performance. Furthermore, the study also unravels how a company's reputation can act as a shield amid the onslaught of the pandemic, thereby moderating the negative relationship between COVID-19 and company performance. The research utilizes 2,847 firm-year observations from non-financial companies listed on the Indonesia Stock Exchange from 2017 to 2022. The analysis employed in this study uses moderated regression analysis (MRA) with STATA software. The results indicate that a company's reputation can moderate, weakening the negative relationship between COVID-19 and company performance. These findings are reinforced by robustness testing using Coarsened Exact Matching (CEM) and alternative performance measurements. This information is highly valuable for companies and stakeholders, indicating that the risks arising from the COVID-19 pandemic can be mitigated by strengthening the company's reputation.

Published: June 2024

Thailand has one of the world's highest road fatality rates, mainly on motorcycles. In mixed traffic, motorcycles coexist with other vehicles. The interaction between cars and motorcycles, such as overtaking due to speed differences, can lead to accidents. This scenario also has implications for autonomous vehicles interacting with motorcycles. To increase safety in such interactions, a model was developed that simulates overtaking maneuvers of car drivers with motorcycles, using the concept of comfort zone boundary and a four-phase classification. In a driving simulator, 648 overtaking maneuvers collected from 36 Thai drivers were recorded with different lateral positions and speeds of the motorcycles. A novel graphical method using steering wheel angle and steering wheel velocity signals facilitated the identification of the phases. Time-to-collision and lateral distance characterized driver comfort zones and served as an indicator for safety measures. The lateral position of the motorcycle has proven to be the most influential factor in the model. The results suggest that overtaking vehicles exhibit non-lane-bound driving characteristics and a risk for the sideswipe accident is identified. These results provide a foundational framework for advanced driver assistance systems and motion planning of autonomous vehicles, contributing to improved road safety.
Elastic Damage Healing Model Coupling Secondary Damage Variable for Self Healing Materials
Authors: Subramanian Harini , Mulay Shantanu S
Published: June 2024

A one-dimensional constitutive model, based on the principles of continuum damage mechanics, is developed for capturing healing in certain materials during unloading and rest periods. A secondary damage variable   is defined to address the drawback of existing models for damage and healing in capturing the complete material failure. An energy-based damage evolution function is adopted for primary and secondary damage variables, and phenomenological healing evolution is defined. The proposed implicit elastic damage-healing model is implemented by the return-mapping technique, and the model response is demonstrated for different loading histories.
A Unified Mechanics Theory based Damage Model for Creep in Nickel based Superalloys
Authors: Kambhammettu Sri Krishna Sudhamsu , Mangal Saurabh , C Lakshmana Rao , Chellapandi Perumal
Published: June 2024

Unified Mechanics Theory’s (UMT) entropy-based damage parameter, also known as the “Thermodynamic State Index” has been proven to be consistent and useful in predicting the fatigue life of different metal alloys. In recent times, studies have also demonstrated its applicability towards creep damage in nickel-based superalloys under a limited set of conditions. However, the usefulness of the “Thermodynamic State Index” in estimating damage at different temperatures, and creep loads for different metal alloys has not been evaluated yet. In this paper, creep in INCONEL 600 alloy is modeled using Norton’s creep law modified with entropy-based damage (Thermodynamic State Index). The model is calibrated to predict both damage and creep strains for any given input of stress, temperature, and time. The available database on INCONEL 600 is used in parts to both calibrate and validate the prescribed model. The damage evolution for different cases is compared and imminent conclusions are drawn.
Lokale Industriepolitik für kleine Unternehmen: Das Beispiel der Textilindustrie in Herning-Ikast/Dänemark
Authors: Hjalager Anne-Mette
Published: June 2024

Gesunde und gutentwickelte kleine und mittlere Unternehmen sind wichtig für das Wohlergehen moderner Ökonomien, weil sie (l) zur Verteilung von Macht, Verantwortlichkeit, Eigentum und Risiko beitragen und dadurch den Wettbewerb anregen, weil sie (2) arbeitsplatzintensiv sind und daher beträchtlich zur Beschäftigung beitragen, weil sie (3) mit hoher Flexibilität arbeiten, welche für die unvermeidbare ökonomische Umstrukturierung von großer Bedeutung ist, weil sie (4) Gelegenheit geben, in einem überschaubaren Gefüge zu arbeiten, und somit auch eine Humanisierung des Arbeitslebens ermöglichen und schließlich (5) weil sie eine wichtige Rolle für die Angebotsbreite und für die räumliche Verteilung von Güterproduktion und Dienstleistungen spielen. Diese Aufzählung von Positivmerkmalen kleiner und mittlerer Betriebe wurde von einer Kommission des Europäischen Parlaments erarbeitet. Diese Bewertung wird in vielen europäischen Ländern geteilt. Viele Länder haben nationale Programme zur Förderung der kleinen Firmen auf finanziellem und technischem Gebiet eingerichtet.Die Idee, daß kleine Betriebe eine treibende Kraft regionaler Entwicklung sein können, wird auch von vielen lokalen und regionalen Verwaltungen und Entwicklungsträgern geteilt. Für diese Institutionen ist es notwendig, daß sie für die folgende Frage eine Antwort finden: Welches sind die besonderen Merkmale der industriellen Struktur und der kleinen Betriebe in der Region/Gemeinde und was wird unter den regionalen Bedingungen der Inhalt einer lokalen Politik für die kleinen und mittleren Betriebe sein?Das Ziel dieses Artikels ist es, diese Denkrichtung an einem Beispiel zu veranschaulichen. Eine Region in Jütland, die im wesentlichen aus den Städten Herning und Ikast besteht und die von einer kleinbetrieblichen Textil- und Bekleidungsindustrie dominiert wird, wird dazu herangezogen.
Die Beteiligung am Fernstudium unter regionalen Gesichtspunkten
Authors: Balser Wolfgang
Published: June 2024

Auch nach allgemein gestiegener Bildungsbeteiligung wurden starke regionale Unterschiede beim Besuch weiterführender Schulen festgestellt. Der Artikel geht der Fragestellung nach, ob Femstudienkurse geeignet sind, regionale Benachteiligung bei der Bildungsbeteiligung auszugleichen. Dazu wird die regionale Verteilung der Teilnehmer am Funkkolleg „Mensch und Umwelt“ in 1981/82 in Hessen festgestellt und mit Daten zur regionalen Beteiligung an Volkshochschulkursen und zur regionalen Verteilung von Abiturienten in Beziehung gesetzt. Die Auswertung ergibt, daß die relative Beteiligung am Funkkolleg „Mensch und Umwelt“ in Ballungsgebieten und deren Randgebieten erheblich über der in ländlichen Gebieten liegt. Dabei sind die Differenzierungen bei der Funkkolleg-Teilnahme etwa parallel zu denen bei den Abiturientenzahlen festzustellen. Es läßt sich schließen, daß die Femstudienangebote des Funkkollegs nur bedingt regionale Bildungsbenachteiligung kompensieren können.
Strukturgerechte Verkehrsbedienung – eine Aufgabe der Raumordnungs- und Umweltpolitik
Authors: Neidhardt Jochen
Published: June 2024

Der öffentliche Personennahverkehr (ÖPNV) in der Fläche ist allgemein gekennzeichnet durch rückläufige Fahrgastzahlen und Angebotseinschränkungen. Gleichzeitig nimmt der Pkw-Verkehr und die damit verbundene Umweltbelastung weiter zu.Am Beispiel des Nahverkehrsmodells Hohenlohekreis (NVH), das inzwischen in den Dauerbetrieb übergegangen ist, werden Möglichkeiten aufgezeigt, dieser Tendenz wirksam zu begegnen. Grundprinzipien des NVH sind die Umgestaltung des Liniennetzes und der Verkehrsbedienung nach raumordnerischen Kriterien, die vollständige Integration des Schülerverkehrs in den allgemeinen Linienverkehr und die Übernahme einer politischen und finanziellen Gesamtverantwortung des Landkreises für den ÖPNV. Das Ergebnis des NVH ist nach vier Jahren Erprobung eine Verdoppelung des Verkehrsangebotes im allgemeinen Linienverkehr und ein Kostendeckungsgrad von rd. 95 %.Als Perspektive einer umweltorientierten Nahverkehrsplanung wird die Idee eines Verbundes der umweltverträglichen Verkehrsarten skizziert. Um diesen „Umweltverbund“ von Fußgängerverkehr, Radverkehr und öffentlichem Personennahverkehr zu realisieren, wären drei unterschiedliche Modellansätze zu verknüpfen, die weitgehend unabhängig voneinander verfolgt worden sind: die ÖPNV Modelle im Rahmen des Forschungsprogramms Stadtverkehr des Bundesministers für Verkehr, das Modellvorhaben „Fahrradfreundliche Stadt“ des Umweltbundesamtes und das Modellvorhaben „Flächenhafte Verkehrsberuhigung“ des Umweltbundesamtes, der Bundesforschungsanstalt für Landeskunde und Raumordnung und der Bundesanstalt für Straßenwesen.Folgerungen aus einem Forschungsvorhaben der Kommunalentwicklung Baden-Württemberg GmbH Stuttgart „Strukturgerechte Verkehrsbedienung im ÖPNV – Planungs- und Entwicklungsansätze in acht Landkreisen Baden-Württembergs unter Berücksichtigung einer stärkeren Regionalisierung und Effizienzsteigerung des öffentlichen Personennahverkehrs“, F 324.
Unkonventioneller ÖPNV in ländlichen Räumen – Ergänzung oder Alternative?
Authors: Heinze G. Wolfgang
Published: June 2024

Im Mittelpunkt steht eine realistische Einschätzung des ÖPNV im ländlichen Raum und seiner verbliebenen Entwicklungsspielräume.Das ÖPNV-Problem ist generell ein Nachfrageproblem. Bei freier Verkehrsmittelwahl ist die rückläufige Entwicklung der Nachfrage nach Leistungen im ÖPNV-Linienverkehr dünnbesiedelter ländlicher Räume ein normales Wettbewerbsergebnis. Aber: Ohne Werturteile bemühen zu müssen, läßt sich wissenschaftlich begründen, daß die Erhaltung und Förderung des ÖPNV gerade in einer automobilen Gesellschaft zweckmäßig ist. Dabei bilden die peripheren ländlichen Teilräume die besonderen Sorgenkinder der Verkehrspolitik. Aber gerade hier existieren noch erhebliche Gestaltungsspielräume. Dabei ist zu unterscheiden zwischen: (1) den „großen Lösungen von oben“, (2) den „kleinen Lösungen von unten“, (3) dem noch unausgeschöpften Reservoir von Maßnahmen relativ kostenneutraler Nachfragepflege im Linienverkehr und (4) angepaßten, bedarfsorientierten, flexiblen Lösungen. Im Vordergrund sollten in der Zukunft nicht so sehr jene kostspieligen Verbesserungen nach herkömmlichen (großstädtischen) Maßstäben stehen, sondern eher Versuche qualitativer Neuorientierung (in einer Umwelt, in der bezeichnenderweise die Nichtbenutzung eines Pkws zu begründen ist). Dazu gehört auch die stärkere Einbeziehung lokaler Faktoren, lernendes Experimentieren der Planer und die Einsicht, daß Verkehrsleistungen Begegnungen zwischen Menschen bilden. Heute sind die dünnbesiedelten ländlichen Räume die Ränder, wo das Netz reißt. Hier ist deshalb der Zeitpunkt für unkonventionelle Maßnahmen gekommen.Auch im dünnbesiedelten ländlichen Raum hat der ÖPNV mehr als eine Chance. Nur: Die ÖPNV-Zukunft dürfte ein heterogenes mehrstufiges Angebotsraster bringen. Gerade deshalb ist es so wichtig, unerwünschten Entwicklungen ins Auge zu sehen, Auffanglösungen vorzubereiten und sich von liebgewonnenen, aber überkommenen Konzepten zu trennen.

Regionale Strukturpolitik in altindustrialisierten Gebieten
Authors: Pieper Theodor
Published: June 2024

Der Ausdruck „altindustrialisiertes“ Gebiet und die Unterscheidungzwischen „alten“ und „neuen“ Industrien haben eher suggestiven als ökonomischen Charakter und sagen nichts über die internationale Wettbewerbsfähigkeit der jeweiligen Industrie und der sie beheimatenden Region aus. „Altindustrialisierte“ Gebiete stehen zwar vor erheblichen Strukturproblemen, verfügen aber gleichzeitig über ein beträchtliches Entwicklungspotential, das es zu aktivieren gilt. Hierzu haben die sechs Industrie- und Handelskammern des Ruhrgebietes zum Jahresanfang Vorschläge vorgelegt, die nach ihrer Meinung dazu geeignet sind, die notwendige Erneuerung der „altindustrialisierten“ Region Ruhrgebiet zu bewirken. Zur Überwindung von Strukturproblemen gibt es nur den Weg des Strukturwandels. Erforderlich ist daher eine Akzeptanz der Notwendigkeit des Strukturwandels auf allen Ebenen und unter allen Beteiligten. Strukturwandel ist nur möglich durch Investitionen, insbesondere private Investitionen. Es kommt daher alles darauf an, die Voraussetzungen für Investitionen zu verbessern. Die herkömmliche regionale Wirtschaftspolitik reicht angesichts der Dimension der Probleme jedoch nicht aus. Die anstehende Aufgabe ist nur in einer gemeinsamen Anstrengung aller Verantwortungsträger zu bewältigen. Daher haben die Kammern in das Zentrum ihrer Überlegungen den Vorschlag einer konkreten Kooperation zwischen Staat und Wirtschaft gestellt.Die Initialzündung für den notwendigen Strukturwandel soll von der Gründung einer privaten Gesellschaft zur Erneuerung des Ruhrgebiets ausgehen. Diese allein aus Mitteln der regionalen Wirtschaft finanzierte Gesellschaft soll Investoren gewinnen, beraten und ihnen Standorte vermitteln sowie Betriebsverlagerungskonzepte für in ihrer Investitionstätigkeit durch planungsrechtliche Unzulänglichkeiten behinderte Unternehmen entwickeln. Damit diese Initialzündung einen Investitionsschub im Ruhrgebiet auslöst, bedarf sie der Flankierung durch ein wirksames öffentliches Rahmenkonzept, das darauf abzielt, den bestehenden Engpaß an planungsrechtlich gesicherten Flächen zu beseitigen, planungs- und umweltschutzrechtliche Einschnürungstatbestände für Investitionen abzubauen, eine kostenoptimale Energieversorgung zu gewährleisten und durch zusätzliche Abschreibungsmöglichkeiten die mit überdurchschnittlich hohen Umweltschutzinvestitionen einhergehenden Belastungen auszugleichen. Zur Sicherung der Zukunft schlagen die Kammern weiterhin den Auf- und Ausbau einer Technologiestraße Ruhr vor, also eine zielgerechte Weiterentwicklung der bestehenden technologieintensiven Ansätze im Unternehmens‑, Forschungs- und Hochschulbereich. Schließlich gilt es die einmalig dichte Bildungslandschaft des Ruhrgebiets stärker mit der ebenfalls einmaligen wirtschaftlichen Vielfalt zu verbinden und berufliche Qualifikationen ständig durch Aus- und Weiterbildung an technische Veränderungen anzupassen.

Methylphenidate (MPH) has been previously shown to increase resting energy expenditure (REE) in individuals of normal weight; however, the effects on individuals living with obesity are currently unknown. Ten individuals living with obesity were randomly assigned to undergo 60 days of MPH administration with a daily dose of 0.5 mg/kg body weight or a placebo control. REE was measured before and after the 60‐day intervention. There was a trend toward significance for group × time interaction on REE (p = 0.082) with a large effect size (η2 = 0.331), with MPH administration increasing REE compared to a decrease in placebo control. Preliminary findings from this pilot study show that MPH has the potential to counter the adaptive thermogenic process commonly seen in weight loss. This is a unique finding among pharmacotherapies, as no approved obesity drugs measurably impact REE.

Chenopodium ambrosioides aerial parts have been historically employed in traditional medicine for addressing various ailments such as headaches, abdominal discomfort, joint issues, and respiratory disorders, alongside treatments for lice and warts. This study aimed to conduct a comprehensive phytochemical analysis of C. ambrosioides and assess the acute and subacute toxicity of oral treatments using fractions in preclinical trials. Spectrophotometric analysis via LC–MS/MS was used to characterize the plant’s chemical composition. Acute toxicity evaluation followed Organisation for Economic Co-operation and Development code 42 guidelines, conducted on adult male and female Wistar strain mice. Subsequently, Swiss mice were divided into six groups for the subacute toxicity study, receiving oral doses of 200 mg/kg extracts and fractions for 28 days. Daily observations and biochemical analyses were performed, with LC–MS/MS revealing a diverse array of compounds including organic acids, flavonoids, phenolic acids, rutin, hesperidin, nicotiflorine, and fumaric acid. Results indicated no lethality or alterations in body weight in treated groups, though some organ weight changes were noted. Biochemical analyses demonstrated values within the normal range for all groups, suggesting that the treatments did not induce adverse effects. Acute and subacute treatments with fractions did not result in lethality or toxic alterations at therapeutic doses, implying the safety of the product at appropriate levels. This study underscores the potential of C. ambrosioides as a safe therapeutic option warranting further exploration.
Anticancer, antioxidant, and antimicrobial activities of nanoemulsions based on water-in-olive oil and loaded on biogenic silver nanoparticles
Authors: Hamouda Ragaa A. , Eshmawi Bayan A. , Saddiq Amna A.
Published: June 2024

Nanoemulsions (NEMs) are more stable and permeable than regular emulsions because of their increased surface area and smaller particle sizes, which are stabilized by emulsifiers and consist of nanometer-sized droplets. Utilization of an olive oil nanoemulsion (NEM-olive oil) loaded with silver nanoparticles (Ag-NPs) derived from marine alga Turbinaria turbinata may be effective against microorganisms and cancer cell lines. NEM-olive oil was made by mixing olive oil, surfactant (Span:Tween (28:72)), and D water (1:4:5). The marine alga Turbinaria turbinata was used for the synthesis of Ag-NPs (Tu-Ag-NPs), and combined with NEM-olive oil (1:1) to synthesize Ag-NPs loaded in olive oil–water nanoemulsion (Ag/NEM-olive oil). Transmission electron microscopy, energy-dispersive X-ray analysis, zeta potential, Fourier transform infrared, and X-ray powder diffraction spectroscopy were used to characterize the nanoparticles. Both NEM-olive oil and Ag/NEM-olive oil nanoparticles showed a negative surface charge and small diameter. The major components of NEM-olive oil are dodecanoic acid, 2-penten-1-yl ester, 9-octadecenoic acid, and oleic acid. All tested nanoparticles exhibited anticancer activity against the CACO-2 cell line and Hep G2, and antimicrobial activities against E. faecalis, S. aureus, E. coli, and C. albicans. The present research suggested that olive oil NEM loaded with marine algae Ag-NPs can be a safe and economical anticancer, antimicrobial, and drug delivery.

Reproductive genetic carrier screening in pregnancy: improving health outcomes and expanding access
Authors: Mei Jenny Y. , Platt Lawrence D.
Published: June 2024

Reproductive genetic carrier screening (RGCS) serves to screen couples for their risk of having children affected by monogenic conditions. The included conditions are mostly autosomal recessive or X-linked with infantile or early-childhood onset. Cystic fibrosis, spinal muscular atrophy, and hemoglobinopathies are now recommended by the American College of Obstetricians and Gynecologists (ACOG) for universal screening. Recommendations for further RGCS remain ethnicity based. The American College of Medical Genetics and Genomics and the National Society of Genetic Counselors in recent years have recommended universal expanded-panel RGCS and moving towards a more equitable approach. ACOG guidelines state that offering RGCS is an acceptable option, however it has not provided clear guidance on standard of care. Positive results on RGCS can significantly impact reproductive plans for couples, including pursuing in vitro fertilization with preimplantation genetic testing, prenatal genetic testing, specific fetal or neonatal treatment, or adoption. RGCS is a superior approach compared to ethnicity-based carrier screening and moves away from single race-based medical practice. We urge the obstetrics and gynecology societies to adopt the guidelines for RGCS put forward by multiple societies and help reduce systemic inequalities in medicine in our new genetic age. Having national societies such as ACOG and the Society for Maternal-Fetal Medicine officially recommend and endorse RGCS would bolster insurance coverage and financial support by employers for RGCS. The future of comprehensive reproductive care in the age of genomic medicine entails expanding access so patients and families can make the reproductive options that best fit their needs.
How to increase freeze-substitution and electron microscopy embedding reliability
Authors: Heiligenstein Xavier , Kodera Chie , Belle Martin
Published: June 2024

Freeze substitution is a crucial technique in electron microscopy, enabling the preservation of biological specimen ultrastructure. However, existing tools are primarily designed for 3 mm carriers, limiting their compatibility with larger carriers such as CryoCapsules or 6 mm carriers. In this study, we developed a novel freeze substitution tool, simply named the FS-basket, to address the challenges associated with embedding samples vitrified in larger carriers. The tool comprises a mesh with pore sizes smaller than the sample chunks, deposited below the carrier to maintain a tight seal while allowing for easy fluid exchange.
The 4Ps Marketing Strategy as a Driver of Dynamic Capabilities: Path to Consumer/Voter Satisfaction
Authors: Antoniades Nicos , Buoye Alexander
Published: June 2024

Despite the importance of the 4Ps of Marketing in an organization’s growth strategy, limited research was found to examine the 4Ps’ impact on a politician’s capabilities and consumer/voter satisfaction. On the contrary, much attention has been given to the resource-based view tool (RBV); a tool that utilizes a firm’s valuable resources and dynamic capabilities to strengthen performance and achieve customer satisfaction. Via an online questionnaire, this research collected data from U.S. elected politicians. Using principal components regression, the researchers aim to apply specific dynamic capabilities in politics via the 4Ps Marketing Strategy. Important implications are drawn from this study, and suggestions for future studies are provided.
Fundamental Rights in the AFSJ: Strenthening or impediment?
Authors: Cuc Nguyen Thi Kim
Published: June 2024

The Area of Freedom, Security and Justice was created with the entry into force of the 1997 Amsterdam Treaty. This Area, ten years later, has been improved when the 2007 Lisbon Treaty amended the Treaty Establishing the European Community and renamed it the Treaty on the Functioning of the European Union. The Area of Freedom, Security and Justice (AFSJ) is an extensive field of law covering many policies and there is hence an increased risk for fundamen- tal rights violations. To describe the relevance of the protection of fundamen- tal rights within this Area as well as evaluate the effectiveness of fundamental rights, by using the polemic-critical method and analytical-logical method, this paper will focus on the scope of fundamental rights in some of the EU human rights instruments and the scope of these rights and freedoms in the AFSJ. As a result, this paper will answer the question related to the strengthening or imped- iment of fundamental rights as well as the balance between personal rights and collective interests such as security.

Alfonsas Nyka-Niliunas’ Intellectual Provisions in Texts, Diaries and Correspondence from the Late 1950’s to Mid 1980’s
Authors: Blockutė Emilija
Published: June 2024

The text explores the intellectual provisions of the poet Alfonsas Nyka-Niliunas, which began to emerge in the 1940s in the cultural press, and took on a clear form in the 1950s with the publication of the literary magazine “Literatūros lankai”. Nyka-Niliūnas continued to adhere to his intellectual provisions and the evaluations they dictated in the later stages of his life. The article presents Nyka-Niliūnas not only as a poet and translator, but also as an active shaping force in the cultural field and the literary canon, and presents the principles of his work. The analysis also includes fragments of Nyka-Niliūnas’s diary “Dienoraščio fragmentai”, which are proposed to be treated as an autobiographical construction. The article also presents life experiences that did not make it into Nyka-Niliūnas’ published diary, which allows for a new look at Nyka-Niliūnas and the self-representational image he creates.
Clinical case of bone tuberculosis in the foot: involvement of the calcaneus. Diagnostic challenge and possible primary infection
Authors: Ortiz Mayra Ortega
Published: June 2024

Osteoarticular tuberculosis is a rare form of extrapulmonary tuberculosis, and represents a real diagnostic challenge due to its atypical presentation and similarity with other bone pathologies. The case of a 20-year-old male patient with a history of pulmonary tuberculosis treated 5 years ago, who came to the emergency room due to edema, pain and functional difficulty in the ankle and heel, is presented. The computed tomography of the left foot showed a hypodense osteolytic-type lesion that affected two thirds of the calcaneus, thinning of the cortices and involvement in the support area of the calcaneus. Surgical treatment and sample collection were performed, the anatomopathological analysis of which showed the presence of granulomatous cells inside. Tuberculostatic treatment was started, achieving the patient's improvement. The objective is to highlight the importance of early diagnosis based on clinical and radiological findings to facilitate timely intervention and minimize adverse outcomes.
Synergistic Effect of Gentamicin and Iron Oxide Nanoparticles on phzM Gene of Pseudomonas aeruginosa
Authors: Ahmed M.E. , Abdul Muhsin Z.A.
Published: June 2024

The increased use of iron-containing nanoparticles and green synthesis nanoparticles is beneficial and less harmful to the environment and human health. Working antimicrobial peptide functions by inhibiting the virulence factor of Pseudomonas aeruginosa, which is the essential mechanism of drug resistance by possessing an efflux pump important virulent factor. The main aim of the research was to study the effects of synergistic action of gentamicin (GNT) and iron nanoparticles (IONps) to solve the problem of multidrug-resistant P. aeruginosa. Methods. The isolation and identification of multidrug-resistant P. aeruginosa from burns and wound infections were carried out using the VITEK 2 system, and the phzM genes were detected in all the strains. The effectiveness of IONps and their role in reducing phzM gene expression were investigated. Results. The characterization of IONps biologically manufactured using a wavelength spectrum UV-vis spectrophotometer (maximum peak at 600 nm) and tests of atomic force microscopy showed that their diameter reached 34 nm. An electron microscope examination revealed that the produced particles were spherical, indicating good homogeneity and quality of the IONps. The results showed significant down-regulation changes in phzM expression after treatment with GNT and IONps. The result of qRT-PCR in this study revealed that the fold change in the expression of the phzM gene was downregulated in response to the IONps (8µg/mL) + GNT (16µg/mL) combination. Conclusions. One of the justifications for using P. aeruginosa in preparing IONps is that this bacteria needs iron as a growth promoter, which helps in the formation of IONps. The inhibitory effect on the efflux pump gene expression may represent a potential strategy for controlling P. aeruginosa infections.
Excitation Dynamics of the 5p^6 Auger Spectra in Ba + e^– Collisions
Authors: Borovik O.O.
Published: June 2024

The ionization of the 5p6 subshell in Ba atoms has been studied in an electron-impact energy range 23–105 eV by measuring the Auger spectra arising from the decay of the 5p5nln′l′ states. The energy dependences of the ionization cross-section have been obtained for nine states in the 5p55d2, 5p55d6s and 5p56s2 configurations. The analysis of the behavior of the cross-sections made it possible to determine the role of direct and indirect ionization processes involved in the 5p6 ionization of the Ba atom.

Many anti-epileptic drugs use cenobamate, a voltage-gated sodium channel blocker, to the fullest extent. This study investigates the electronic, quantum chemical, and photolytic properties of Cenobamate and its novel designed isomers. The results show that the LUMOs levels are higher than the HOMO energies. The HOMO levels are unpaired and of s-character locally around the chlorine atoms. The reactivity and stability are explained by the frontier molecular energy values and different biochemical descriptors. All isomers have smallest energy gap means with a higher reactivity for biological applications. The most frequent reaction sites are found to be the three acyl carbons in the cenobamate molecule, the chloride related to the phenyl ring, the heterocyclic ring, and the carbonyl oxygen and nitrogen in the ester amide group. The novel isomers have high ability to interact with species, and this takes place either in clinical use or under clinical trials. The isomers are soft compounds, and can easily interact with big soft molecules such as DNA.

Published: June 2024

In this work, biodiesel was produced from waste cooking oil (WCO) via a green catalyst of CaO-ZnFe2O4 modified Al2O3. The catalyst was characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray (EDX), SEM-mapping, Brunauer-Emmett-Teller (BET), transmission electron microscopy (TEM) analyses. The catalyst performance was studied in the transesterification reaction of WCO conversion to biodiesel. The catalytic activity increased with the combination of nanoparticles effect and support catalysts obtained biodiesel yield of nano-Al2O3, nano-CaO, ZnFe2O4, CaO-ZnFe2O4, and CaO-ZnFe2O4/Al2O3 is 36.86%, 67.16%, 74.83%, 86.54%, and 93.41%, respectively. The best biodiesel yield was 93.41% with a mass ratio of Al2O3 to CaO-ZnFe2O4 (2:1). The physicochemical properties (acid number, density, kinematic viscosity, flash point, and cetane number) of biodiesel under the optimal conditions agreed with the ASTM standard. These results show that the developed nanocomposite has great potential to reduce biodiesel production costs because derived from WCO. In conclusion, CaO-ZnFe2O4 modified Al2O3 as a catalyst has a high potential for biodiesel production on a large scale.

Published: June 2024

BACKGROUND AND OBJECTIVES

Surgery is one of the most common indications for opioid prescribing to pediatric patients. We identified which procedures account for the most pediatric surgical opioid prescribing.

METHODS

We conducted a cross-sectional analysis of commercial and Medicaid claims in the Merative MarketScan Commercial and Multi-State Medicaid Databases. Analyses included surgical procedures for patients aged 0 to 21 years from December 1, 2020, to November 30, 2021. Procedures were identified using a novel crosswalk between 3664 procedure codes and 1082 procedure types. For each procedure type in the crosswalk, we calculated the total amount of opioids in prescriptions dispensed within 3 days of discharge from surgery, as measured in morphine milligram equivalents (MMEs). We then calculated the share of all MMEs accounted for by each procedure type. We conducted analyses separately among patients aged 0 to 11 and 12 to 21 years.

RESULTS

Among 107 597 procedures for patients aged 0 to 11 years, the top 3 procedures accounted for 59.1% of MMEs in opioid prescriptions dispensed after surgery: Tonsillectomy and/or adenoidectomy (50.3%), open treatment of upper extremity fracture (5.3%), and removal of deep implants (3.5%). Among 111 406 procedures for patients aged 12 to 21 years, the top 3 procedures accounted for 33.1% of MMEs: Tonsillectomy and/or adenoidectomy (12.7%), knee arthroscopy (12.6%), and cesarean delivery (7.8%).

CONCLUSIONS

Pediatric surgical opioid prescribing is concentrated among a small number of procedures. Targeting these procedures in opioid stewardship initiatives could help minimize the risks of opioid prescribing while maintaining effective postoperative pain control.
Análisis entrópico y fractal de la distribución espacial de la sismicidad en un sector de Cuba occidental y su relación con el régimen tectónico de la Falla Pinar
Authors: Pazo-Arango Marcos Enrique
Published: June 2024

El objetivo principal de este trabajo es la caracterización de la actividad sísmica vinculada a la Falla Pinar en la región de Cuba Occidental, mediante el empleo de métodos matemáticos que permitan caracterizar y/o cuantificar la relación espacio–tiempo en dicha serie sísmica. A la par de este análisis se realiza una interpretación y correlación de los resultados obtenidos con los derivados de investigaciones anteriores. Para dar solución al problema de este trabajo se determinan cuatro parámetros fundamentales mediante la aplicación de métodos matemático–estadísticos: la entropía de Poisson, la estimación de las dimensiones generalizadas , el valor  de la relación Gutenberg–Richter y el exponente de Hurst. La integración de los criterios que ofrecen estos parámetros contribuye a la interpretación de la neotectónica de la región desde el punto de vista sísmico y permite a su vez la creación de registros símicos más completos que los actuales. Entre los principales resultados obtenidos está la demostración de que la serie sísmica de la región cumple con la hipótesis de Hurst, donde la mayoría de los fenómenos naturales se comportan como tendencias estadísticas con ruido estocástico y no como caminatas aleatorias. Esto facilita la relación entre los resultados de la investigación y los fenómenos recientes que rigen la neotectónica en el área
Apresentação e tradução do ensaio de Emmanuel Levinas
Authors: Dias de Andrade André
Published: June 2024

O texto inédito em língua portuguesa, Nome de um cão ou o direito natural, reúne os principais temas com que se ocupa a filosofia de Levinas, expostos de modo sutil, embora unidos a um relato dramático ambos característicos do estilo do autor. Sua principal preocupação é ali exposta em sua inevitabilidade, mas também em sua dificuldade mais própria. Trata-se da descoberta da transcendência como aquilo que motiva o pensamento e a ação, da filosofia à sua assunção como ética. Nesta apresentação seguida pela tradução ‒ é possível distinguir e compreender três articulações realizadas pelo ensaio do autor. Primeiro, na relação entre guerra e paz na constituição da filosofia. Segundo, na relação entre humanidade e animalidade consoante à ética. Por fim, na relação entre passado e futuro como indicativa da tarefa última tanto da filosofia quanto da ética.

Bu çalışmanın amacı kurumsal bilgi sistemleri çerçevesinde benimsenen yaklaşımlardan biri olan ürün yaşam döngüsü yönetimi uygulamalarının savunma sanayii kuruluşlarında yapılandırılması sırasında dikkat edilmesi gereken unsurlara ilişkin bir değerlendirme sunmaktır. Bu kapsamda çalışmada büyük ölçekli bir savunma sanayi şirketinde pilot uygulama olarak yapılandırılan sistemin kullanımına yönelik tespitlere odaklanılmaktadır. Çalışmada betimsel yöntem kullanılmıştır. Bu doğrultuda bir savunma sanayii şirketinde kurulan ürün yaşam döngüsü yönetimi sistemini deneyimleyen çalışanlardan anket tekniğiyle veri toplanmıştır. 164 çalışanın yanıtlarını içeren anketlerden elde edilen veriler tanımlayıcı istatistiklerle ve ki-kare değerleri ile sunulmuştur. Bulgulara göre katılımcıların dörtte üçünden fazlası (%75,9) kullandıkları kurumsal sistemler arasında veri taşımaya gereksinim duymaktadır. Katılımcıların %39’u şirkette yapılandırılan pilot uygulamaya kolay alıştığını düşünmektedir. Diğer yandan katılımcıların %35,4’ü aranan bilginin bulunması konusunda, %31,1’i de arayüz kullanımı konusunda zorluk yaşamaktadır. Katılımcıların %42,9’una göre süreçlerin ve sistemin entegre edilmesinde izlenen strateji yetersizdir. Karşılaşılan olumsuzluklara rağmen katılımcıların dörtte üçünden fazlası sisteminin tüm şirkette yapılandırılmasını faydalı ve çok faydalı olarak değerlendirmiştir. Araştırma sonuçları analiz edilen savunma sanayi şirketinde sistemin yapılandırılmasından sonra çoğunlukla arayüz ve bilgi erişimle ilgili konularda zorlukların yaşandığını yansıtmıştır. Bununla birlikte çalışanların çoğunun sistemin yapılandırılma sürecinde izlenen stratejide eksikliklerin olduğunu düşündükleri anlaşılmıştır. Bununla birlikte çalışanların önemli bir bölümü sistemin iş süreçlerine olumlu bir katkı sağladığı görüşündedir. Sonuçlar ayrıca ürün yaşam döngüsü yönetimine dönük sistemlerinin yapılandırılmasında karşılaşılan zorlukların azaltılması ve izlenen stratejilerin iyileştirilmesi için çalışan deneyim ve geri bildirimlerinin süreçlere dahil edilmesi gerektiğini vurgulamıştır.

Authors: Patricia Sánchez-Holgado  , Calderón Carlos , Margarita Tovar Torrealba
Published: June 2024

El reconocimiento de la presencia y relevancia de la información sobre cambio climático en los medios de comunicación es un tema primordial de cara a nuevos objetivos y desafíos globales, como la Agenda 2030 para el Desarrollo Sostenible. Estamos presenciando una configuración de la opinión pública a través de las redes sociales, especialmente Twitter, por lo que su análisis puede ser relevante para abordar los desafíos de la información ciudadana, construyendo un espacio interactivo de opinión pública. El objetivo de este trabajo es revisar la presencia de mensajes sobre cambio climático en Twitter en España y analizar el contenido publicado en 2022, atendiendo al emisor, el mensaje, los enfoques y el tratamiento, comparándolo con análisis similares desarrollados en los tres años anteriores (2019, 2020, 2021) incorporando una perspectiva longitudinal. Con una metodología cuantitativa, este estudio aplica un protocolo de análisis de contenido, con 35 variables, ejecutado por codificadores humanos, sobre una muestra final de 753 tweets, publicados entre los meses de marzo y junio de 2022. Las conclusiones orientan sobre quienes son las voces más activas, los temas principales, la visibilidad de los jóvenes y los efectos más comentados, a la vez que se aprecian las consecuencias del conflicto armado con relación a la transición ecológica, como el retorno y la dependencia económica de los combustibles fósiles, el efecto de las sanciones internacionales sobre la energía, el replanteamiento de las políticas de suministro, la reducción de alimentos y las emisiones de gases de efecto invernadero en Europa. También se consideran variables nuevas para incluir en futuros estudios, como la perspectiva ética de la información y el discurso de odio y negacionismo hacia el cambio climático presente en esta red.
Hospitals’ Corporate Communication Initiatives during the Covid-19 Outbreak: Experiences, Challenges and Future Opportunities
Authors: Medina Aguerrebere Pablo , Gonzalez Pacanowski Toni , Catalan Matamoros Daniel
Published: June 2024

The Covid-19 pandemic led hospitals to work differently with regards to legal procedures, eHealth services. etc., and brought a changing and fluctuating health care environment that affected communication relations among clinicians, patients, and families.  These organizations were also forced to make their corporate communication initiatives more efficient and interact with stakeholders differently, especially with patients and media companies. This paper aims to better understand what were the main corporate communication initiatives implemented by hospitals during the Covid-19 pandemic. We show that the most important communication initiatives implemented by hospitals during the Covid-19 outbreak were related to the following main areas: a) professional management of corporate communication, b) transparency, c) human values, d) hospital’s brand, and e) online corporate communication. During the pandemic, there was a lack of professional corporate communication in hospitals, as well as the need to execute more than merely conservative communication strategies. There is a strong need to professionalize corporate communication efforts in hospitals.
