Authors: Altofan Noor Kadum Naser
Published: February 2025

The purpose of the presented study was to evaluate the contamination of nuts with fungi producing toxins, especially ochratoxins causing serious negative impact on human health. It was found out that Aspergillus spp had contaminated all droplets from different locations of Karbala Governorate. Aspergillus niger was the most frequently isolated species of the fungal isolates at a rate of 100%, due to its significance as a prominent producer of mycotoxins within the Aspergillus genus. Sorghum was used as growing medium for the fungus and the mycotoxins produced were subsequently extracted .The results of detecting the mycotoxin Ochratoxin A using HPLC technology indicated that all fungal isolates produced Ochratoxin. The most productive isolate was identified as KH3AN. Subsequently, the molecular identification of this fungal isolate was performed, and it was registered in the Gene Bank. Significant differences between plant extracts in inhibition of the fungal isolate under laboratory conditions were shown, some extracts showing high activity. Moringa and coriander extracts showed the highest % inhibition of fungal growth, which were 93.32% and 90.54%, respectively, when compared with untreated fungal control (0.00% inhibition). These were followed by sage and clove extracts, which exhibited moderate inhibition percentages of 64.12% and 52.54%, respectively, compared to the control treatment at 0.00%. Accordingly, Moringa and coriander extracts were selected as the most effective plant extracts for use in this study. The results of calculating the percentage of fungal contamination in nut seeds after 21 days of the storage experiment indicated that the combination of Moringa and coriander extracts was highly effective, reducing the contamination rate to 22% compared to the pathogen-only treatment, which reached 100%. This corresponds to an average fungal inhibition rate of 78%. The Moringa extract alone followed in effectiveness, reducing the contamination rate to an average of 35% with an inhibition rate of 65%. The coriander extract treatment achieved a 38% reduction in infection rate, with an inhibition rate of 62% compared to the control. Additionally, the results of ochratoxin production analysis showed that the combination of sage and coriander extracts significantly reduced mycotoxin production to 1.67 μg/kg, compared to the pathogen-only treatment, which recorded 72.54 μg/kg. This was followed by the Moringa extract, which reduced toxin production to 3.30 μg/kg, while the coriander extract alone ranked last, reducing production to 3.87 μg/kg.

One of the fundamental biological sciences, microbiology is crucial to understanding life's processes and has been at the forefront of study in this area. Many of the significant discoveries made over the past few decades that have served to clarify the basic ideas of molecular biology, biochemistry, and genetics came from research with microorganisms. Employers of labor are quite concerned about the quality of microbiology graduates coming out of our educational schools and their lack of readiness for employment. They contend that academic standards have significantly declined over the years and that a certificate, OND/HND, or BSc from a university does not imply that the holder is technically or communicatively competent. A few techniques have been used to improve instruction. Several techniques have been used to enhance the teaching of microbiology, including the use of posters and PowerPoint presentations, social networking sites (such as Facebook and ASM Connect), virtual simulators, and service learning techniques. Lack of money, subpar teaching facilities, a reduction in staff quality, and out-of-date curricula are all barriers to teaching microbiology. To reverse this situation and improve the effective teaching and learning of microbiology in higher institutions, measures such as effective funding of microbiology departments, improvement organizations of teacher's training and workshops, and use of electronic tools for teaching should be put into place. The current microbiology teaching materials may be digitalized and made freely available online, which would greatly expand the learning opportunities for both students and microbiology educators of medically related courses of study. Emphasis is also placed on teaching microbiology in an advanced manner, making use of all the benefits that contemporary techniques and methods offer. Results and criticism related to advancements in microbiology teaching techniques could be networked and disseminated among stakeholders.

Lorsque l’on entend parler de goudron, on ne peut s’empêcher de penser immédiatement aux routes, aux travaux publics, et on se demande bien ce que l’archéologue pourrait trouver d’intéressant à étudier une telle chose. Et pourtant! Le conducteur se doute- t-il que le goudron sur lequel il circule est utilisé par l’être humain depuis au moins 200 000 ans ? Que celui-ci a des usages extrêmement nombreux et variés, et que presque toutes les civilisations l’ont utilisé sous différentes formes ? Probablement pas, et c’est pourquoi l’archéologie des goudrons est aujourd’hui un véritable sujet d’étude. Car du goudron, nous en trouvons! Qu’il s’agisse de blocs entiers ou de résidus sur des objets, il y a peu de sites archéologiques qui n’en présentent pas même d’infimes traces.
GRAPHITES AND GRAPHITE-LIKE MATERIALS AS MICROWAVE ACCEPTORS IN THE SYNTHESIS OF CARBON NANOSTRUCTURES
Authors: Zaritovskii Aleksandr N. , Kotenko Elena N. , Grishchuk Svetlana V. , Glazunova Valentina A. , Volkova Galina K.
Published: February 2025

The work examines a number of solid carbon materials as acceptors that accumulate and convert microwave (MW) energy into thermal energy in the processes of synthesis of carbon nanotubes (CNTs) using the energy of microwave electromagnetic field. Graphites of different grades, thermally expanded graphite (TEG), graphite oxides, activated carbons, blast furnace coke, and carbon black have been studied as acceptors. Ferrocene was used as a metal catalyst precursor and carbon donor. The experiments were carried out by treating a mixture of acceptor and ferrocene in a 1 : 1 ratio with MW radiation of 2450 MHz frequency and 1 kW power. In most experiments, the process was accompanied by the formation of micro-arc discharges, leading to a rapid increase in the temperature of reaction mixture. The structure and morphology of the obtained carbon materials were investigated by electron microscopy and X-ray phase analysis. It was shown that experiments involving most of the studied microwave acceptors lead to the formation of carbon nanostructures, consisting mainly of multi-walled carbon nanotubes of characteristic “match” morphology with diameters in the range of 16-90 nm and few-layer graphene particles. In addition to the main components, the synthesis products contain carbon structures of a different morphology. Thus, in processes involving MKKZ graphite, bamboo-shaped CNTs and giant carbon tubes with a diameter of up to 450 nm and a length of up to several micrometers were identified. In the case of TEG, toroidal nanotubes were recorded, while in reactions with AG-3 activated carbon, the formation of CNTs with a helical morphology was observed. It was established that the studied acceptors demonstrate high microwave activity. It was found that the thermotransforming properties of graphite, TEG and coke are at the same level and significantly exceed those for active carbons and carbon black.

STUDY OF THE PURIFYING FLOTATION POTASSIUM CHLORIDE PROCESS FROM AMINES USING ULTRASONIC TREATMENT
Authors: Podtynova Aleksandra S. , Cherepanova Marija V. , Lanovetskiy Sergey V.
Published: February 2025

In the technology of flotation enrichment of sylvinite ore, aliphatic amines are widely used, which are effective collecting reagents that provide high KCl recovery. Amines typically contain 16 to 22 carbon atoms in the aliphatic chain, making them virtually insoluble in water. By adsorbing on the surface of sylvite, amines create a hydrophobic surface, ensuring the floating of potassium chloride particles and their separation from halite. The presence of a hydrophobic amine film on the surface of the KCl flotation concentrate significantly impairs the efficiency of its pressing and contributes to a decrease in the quality of the finished product. The presented work presents studies on the purification of the crystalline surface of flotation potassium chloride from aliphatic amines using ultrasonic treatment, as well as an assessment of the strength of granular potassium chloride obtained from flotation crystallisate subjected to ultrasonic treatment. It has been shown that with an increase in the intensity of ultrasonic treatment of a suspension of flotation potassium chloride from 20 to 50 W/cm2, the mass fraction of aliphatic amines in the samples decreases, regardless of the duration of treatment. With an ultrasonic irradiation intensity of 40 W/cm2 for 60 s, it is possible to maximally reduce the concentration of amines in the finished crystalline product from 130 to 32 g/t. It has been established that with increasing pressure and pressing time of flotation potassium chloride, an extreme change in the average static strength of the resulting granules occurs. Thus, when the pressing pressure changes in the range from 3 to 15 MPa with a constant holding time of 30 s, the static strength of the granules reaches its maximum value at 10 MPa. Research on the influence of the effectiveness of parameters of ultrasonic cleaning of potassium chloride flotation concentrate from aliphatic amines on the process of pressing crystalline particles showed that 60 s cleaning at an ultrasound intensity of 40 W/cm2 made it possible to achieve maximum static strength of granules σ = 210.2 N/granule and hardening coefficient K = 1.36. The results of the presented studies can be used in the design of technology for pressing flotation potassium chloride at potash concentration plants.

PLASMA PARAMETERS AND FLUORINE ATOM DENSITY IN SF6 + Ar + He GAS MIXTURE: EFFECTS OF Ar/He MIXING RATIO, PRESSURE AND INPUT POWER
Authors: Miakonkikh Andrey V. , Kuzmenko Vitaly O. , Efremov Alexander M. , Rudenko Konstantin V.
Published: February 2025

The influence of the initial mixture composition, gas pressure and input power on electro-physical parameters and density of fluorine atoms in SF6 + Ar + He plasma produced in an inductive-type reactor at 2 MHz was investigated. The combination of plasma diagnostics by Langmuir probes and optical emission spectroscopy allowed one to determine behaviors of electrons- and ions-related plasma characteristics vs. variable operating parameters as well as to suggest mechanisms responsible for corresponding effects. In particular, it was shown that the substitution of argon by helium at constant SF6 content in a feed gas affects the electron temperature, densities of charged species and plasma electronegativity through changes in both total ionization rate and electron energy losses during their interactions with dominant neutral particles. It was found that input power produces the maximum effect on the F atom density (by ~ 9 times at w = 800–1250 W) while the influence of the Ar/He ratio and gas pressure (especially at p < 15 mtorr) appears to be much weaker. Such situation is caused by opposite trends of electron temperature and electron density that results in rather small changes in the effective frequency of SFx + e → SFx-1 + F + e reaction family. It was found that fluxes of both fluorine atoms (ГF) and positive ions (Г+) follow changes in their densities, and the minimum ГF/Г+ value in He-rich plasmas corresponds to low pressures and input powers.

SYNTHESIS AND PHOTOCATALYTIC PROPERTIES OF CERIUM OXIDE IN THE DEGRADATION OF 2,4-DICHLOROPHENOXYACETIC ACID: INFLUENCE OF SYNTHESIS METHODS
Authors: Hao Nguyen Hoang , Lan Phung Thi , Giang Nguyen Thi Kim , Chau Cao Hoang Minh , Ha Nguyen Thi Thu
Published: February 2025

Ceria (CeO2) was synthesized using three different methods: hydrothermal synthesis with water solvent and OH- agent, hydrothermal synthesis with ethanol solvent, and solvothermal synthesis. The synthesized materials were characterized using a range of advanced techniques, including Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD), X-Ray Photoelectron Spectroscopy (XPS), and UV-Visible Diffuse Reflectance Spectroscopy (UV-Vis DRS). The photocatalytic activity of the synthesized CeO2 materials was evaluated through the degradation of 2,4-dichlorophenoxyacetic acid (2,4-D), a common herbicide. The results indicated that CeO2 synthesized using the hydrothermal method with ethanol solvent had the smallest particle size, ranging from 35 to 55 nm. This small particle size is beneficial for photocatalytic applications as it provides a larger surface area for catalytic reactions. Consequently, this CeO2 material exhibited excellent photocatalytic activity, achieving a degradation efficiency of up to 54.14% for 2,4-D. Kinetic studies of the degradation process were conducted using a pseudo-first-order reaction model based on the Langmuir-Hinshelwood mechanism. These studies revealed that the degradation rate constants of 2,4-D on CeO2 catalysts synthesized by the different methods were quite similar, suggesting that the synthesis method primarily influences the particle size and surface properties rather than the intrinsic catalytic activity. These findings highlight the importance of optimizing synthesis methods to enhance the photocatalytic efficiency of CeO2 materials for environmental remediation applications.

El estudio se sitúa en el marco de Nueva Escuela Mexicana, currículo para educación básica en los Estados Unidos Mexicanos. Se considera a la supervisión escolar como una función importante en la concreción de las políticas educativas, en la organización y funcionamiento de las escuelas. Se plantea que conviene que las reformas educativas se ocupen del rol que cumple la supervisión y de facilitar las condiciones para su transformación de su papel de control en una actuación donde se focalice lo pedagógico y brinde acompañamiento en los problemas propios de la escuela, pues el proceso de acompañamiento requiere tiempo, empatía, buena comunicación, y conocimientos para orientar. Se asume necesaria una nueva profesionalidad, considerado el patrimonio profesional que posee el supervisor: todas las cualidades que posee en cuanto persona y las experiencias adquiridas en su trayectoria laboral que se fortalecerán con la actualización. Se requiere una gestión horizontal y trabajo colaborativo con las escuelas. Un trabajo que articule conocimiento y acción, ética y eficacia. Se propone el liderazgo transformacional porque promueve un cambio, logra asistir las necesidades individuales y colectivas de su colectivo. El estudio indaga qué profesionalidad los supervisores escolares deben ejercer desde la perspectiva de los directores de educación primaria. Los instrumentos de recogida de información fueron entrevistas en profundidad con supervisores y directores. Los resultados plantean la horizontalidad, entendida como la forma de gestionar las acciones, involucrando a todos y estableciendo el diálogo. Los directivos reconocen necesario un liderazgo transformacional, requieren que el supervisor motive y acompañe en los cambios que implementan en la gestión escolar y en la práctica docente. También un supervisor empático y carismático, que conozca el contexto de sus escuelas y  a la comunidad escolar. En suma, que atienda necesidades colectivas e individuales con un enfoque humanista.

Published: February 2025

This research aims to describe and analyze the significance of the implementation of hidden curriculum-based dhikr manaqib education in Islamic educational institutions. The research method used is library research. The results of his research show that the implementation of hidden curriculum-based dhikr manaqib education has a very significant role, because dhikr manaqib education will make: 1) students strengthen their faith. The human soul will be monitored by what and who always sees it.  Remembering Allah means forgetting others, remembering others means forgetting Him.  Forgetting Him will have far-reaching impacts on human life; 2) students can avoid danger. In this life, a person cannot escape the possibility of danger.  This lesson can be learned from the incident of Prophet Yunus As being swallowed by a fish. At such a time Yunus As prayed: la ilaha illa anta subhanaka inni kuntu minadh dhalimin (there is no god but you, holy are you, verily I am one of the wrongdoers). With prayer and dhikr, Yunus As was able to come out of the fish's stomach; and 3) students can heal their souls. Islam as a religion rahmatan lil alamin offers a concept of developing divine values ​​in a person's mind. Prayer, for example, which contains prayers and dhikr, can be seen as malja, this is Islam's mission to soothe the human heart. Functional dhikr will bring benefits, including bringing happiness, calming the soul, medicine for liver disease and so on.

Published: February 2025

Serang Banten City State High School 3 is the only State High School in Banten Province designated by the Regional Government of Banten Province to accept student athletes to attend school and receive formal education. The dual role of being an athlete and a student does not work well because a student athlete routinely faces challenges in carrying out a busy schedule, which includes training, sports competitions, and school assignments, which can affect their learning performance. In the learning process they need a learning model that combines face-to-face (conventional) learning and online learning. By developing and implementing a rotation type blended learning model, student athletes can learn according to their wishes when they will start studying and when they will finish learning and can determine their own place of study without having to go to the classroom. This learning combines various technologies, learning strategies and delivery methods to achieve learning goals to improve learning outcomes and experiences for student athletes, so that this model can be applied to any subject and anywhere. This research is a type of descriptive research. The results of this research show that student athletes need learning that integrates technology through websites using LMS software called M-learning which is designed to complement the development of the rotation type blended learning learning model. By utilizing technology in developing the rotation type blended learning model, it can create a more effective, efficient and interesting learning

Brassicaceae is taxonomically diverse and economically important plant lineage. Species identification and taxa relationship in this group often poses taxonomic problems particularly in temperate geographic regions. The present work was aimed at testing the evolutionary and systematic potential of leaf epidermal microscopic characters in Brassicaceae of Swat Pakistan. Epidermal preparations and microscopy are based on specimens of Brassicaceae collected from wild populations of the plants from different areas of the district. In total 27 species in 21 genera of the family were subjected to epidermal preparations. Ordinary epidermal cells ranged from polygonal (often), to pentagonal, hexagonal and tubular in shape (rare). Size of ordinary epidermal cells ranged from 40_373.5 µm. Three different types of stomata were examined in the studied species i-e anomocytic, staurocytic and anisocytic. Anomocytic stomata were observed only in Euclidium syriacum. Staurocytic type of stomata were found only on the adaxial surface of Nasturtium officinale. Size of stomata ranged from 15_40 µm. Size of stomatal pore ranges form (2-5) µm. Size of stomatal complex ranged between (40-200 µm). Only non-glandular trichomes were observed i-e stellate, unicellular, branched, T-shaped and Y-shaped.

Published: February 2025

Children’s Mercy Hospital (CMH), a 390-bed free-standing paediatric hospital in Kansas City, Missouri, implemented a formalised patient progression programme in 2022 to enhance patient throughput from pre-arrival to discharge. Utilising Lean process improvement methodologies, CMH identified 88 projects aimed at improving patient progression. In May 2023, CMH opened a patient progression hub, centralising key teams and integrating advanced technology to monitor and manage patient flow. A significant emphasis was placed on discharge and care coordination, with the mission of ensuring safe and timely discharges. Important initiatives included hiring a discharge expediter (DE) to address discharge barriers and implementing projected discharge date (PDD) and clinical readiness date (CRD) to improve discharge transparency and preparation. The patient progression hub features technology from GE Healthcare, with 16 screens continuously displaying pertinent throughput information such as organisational capacity, emergency department (ED) capacity, planned and confirmed discharges, and patients needing transfer from the intensive care unit (ICU) to the medical/surgical units. This real-time data sharing has been crucial in coordinating care and expediting discharges to address system bottlenecks. Additionally, CMH introduced ‘lightning rounds’, which are quick multidisciplinary huddles to review discharge needs. Afternoon rounds were implemented to facilitate continuous communication between charge nurses and care managers. These efforts, supported by innovative technology, have led to substantial improvements in patient outcomes. Timely, well-coordinated discharges have reduced hospital stay durations, minimised readmission rates and enhanced overall patient satisfaction. The initiatives have also resulted in improved capacity management, allowing CMH to better serve its patient population and ensure high-quality, patient-centred care.

A predominant reason employees leave their academic healthcare organisation is career advancement. This reason has been on the rise with the market favouring candidates, given a shrinking supply of qualified healthcare workers. This study showcases intentional interventions to support advancement of employees into leadership roles. The University of Texas MD Anderson Cancer Center (MDA) tackled career advancement through a committee with two priority areas. First, it focused on providing learning, sponsorship and mentoring opportunities, offering initiatives such as an annual sponsorship workshop, an education series and formal sponsorship/mentorship requirements. Secondly, the committee aimed to increase visibility and serve as a national model for advancing healthcare leaders, employing metrics like engagement survey scores and tracking internal movement into leadership roles. The institution’s efforts and initiatives have yielded positive outcomes, evidenced by increased engagement survey scores and by an increased rate of internal hires into leadership roles. Participant feedback from the sponsorship workshop underscores its effectiveness in career development and leadership preparation. The committee emphasises sustained efforts to build on its success, with ongoing commitment to visibility metrics and leadership development. The demonstrated success of MDA’s approach positions it as a replicable model for other academic healthcare organisations seeking to retain talent in leadership.
La política monetaria en Japón: lecciones a extraer en la comparación con la de los EE.UU.
Authors:   Banco de España, García Herrero Alicia , Martín Machuca César ,   Banco de España
Published: February 2025

La experiencia de Japón muestra que la deflación es un fenómeno que requiere unas circunstancias especialmente negativas, en la que no parece encontrarse actualmente la economía norteamericana. La primera lección a extraer es que la deflación tiene costes muy elevados y es difícil de anticipar. Por este motivo, es importante que las autoridades monetarias reaccionen rápida y decididamente para evitar tipos de interés nominales nulos, ya que se reduce sustancialmente la efectividad de la política monetaria cuando se llega a ese límite. Antes de alcanzar tipos nominales nulos, una meta explícita de inflación y el mantenimiento de los tipos de interés en niveles muy bajos durante un periodo predeterminado parece lo aconsejable. Si ya se hubieran alcanzo tipos nulos, las autoridades disponen de ciertos medios para atajar el problema de la deflación, entre ellos políticas monetarias más heterodoxas, una expansión fiscal sustancial y/o una rápida depreciación del tipo de cambio. Estas opciones no están exentas de costes para el balance del banco central, la sostenibilidad de las cuentas públicas y la estabilidad monetaria internacional, pero son inferiores a los costes derivados de una situación permanente de deflación y de estancamiento económico.
Riesgo de deflación en EE.UU.: ¿Un temor justificado?
Authors:   BBVA, Martínez Montse , Torres Xavier Torres ,   BBVA
Published: February 2025

Tras la desaceleración de la actividad iniciada en 2001, el crecimiento de la economía de EE.UU. se ha mantenido por debajo de su potencial y la inflación se ha situado en mínimos históricos. Ello ha llevado a temer que la economía estadounidense pueda sufrir un episodio de deflación prolongado, similar al experimentado por la economía japonesa desde los años noventa con elevados costes en términos de producción agregada y desempleo. Teniendo en cuenta la experiencia nipona, este trabajo trata de determinar hasta qué punto los factores de riesgo existentes están justificando el temor a la deflación en EE.UU. desde una óptica macroeconómica. Para ello se analizan las proyecciones de inflación realizadas con distintos instrumentos de predicción, el efecto de las ganancias de productividad sobre la tasa de inflación, el grado de capacidad excedente en la economía de EE.UU., la evolución de los precios de los activos y, por último, el papel de las políticas económicas, tanto monetaria como fiscal. En conjunto, los resultados ponen de manifiesto que la deflación es un escenario poco probable en la economía estadounidense.

Este acuerdo se engloba y se analiza dentro de un proceso general con tres dimensiones principales: a) la tradición en la relación Gobierno-Industria y en la organización social de los intereses empresariales e industriales; y b) el proceso de interacción que en dos direcciones (gobierno-industria e inter-empresarial) va a construir nuevas identidades e intereses colectivos; y c) el aprendizaje social, por el que se ha desarrollado una prometedora colaboración sinérgica entre el Gobierno y la Industria vasca.

La incorporación de tecnologías de información y redes de comunicaciones en todos los ámbitos sociales también ha afectado a las tareas de Gobierno y Administración. Dentro de esta dinámica se han originado de manera creciente estudios sobre Gobierno Electrónico (a partir de ahora e-Gobierno), aunque con escasa claridad sobre los enfoques existentes, el contenido del propio concepto y sus límites. Este artículo aborda esta problemática considerando tres dimensiones del concepto (e-Administración, e-Democracia y e-Gobernanza); los roles asociados a los gobiernos y administraciones públicas (prestadores de servicios públicos, promotores de la democracia y dinamizadores del proceso de elaboración de políticas públicas), teniendo en cuenta las nuevas oportunidades ofrecidas por el uso de las Tecnologías de la Información y la Comunicación (TIC) e Internet; y los diferentes actores críticos involucrados en el desarrollo de proyectos de e-Gobierno. La conclusión principal de este artículo supone la importancia de los diferentes actores críticos a la hora de desarrollar y mejorar la actividad pública y la necesidad de considerar las tecnologías como una oportunidad para caminar hacia gobiernos y administraciones públicas con un carácter relacional, más allá de meras etiquetas relacionadas con las modas y momentos concretos.

Este trabalho tem por objetivo desenvolver um guia digital para o cuidado inicial de enfermagem ao paciente com Acidente Vascular Cerebral agudo. Trata-se de uma pesquisa realizada por meio de uma revisão integrativa e aplicação de instrumentos de validação do conteúdo e aparência do guia digital a seis juízes da área de enfermagem. Utilizou-se o índice de concordância para o cálculo da validade.  Entre os principais resultados, destaca-se a baixa produção de estudos acadêmicos brasileiros na área de atendimento inicial. Desse modo, o conteúdo do guia foi produzido com base na revisão e documentos institucionais de uma Unidade de Pronto Atendimento de um município do Nordeste brasileiro. A partir da avaliação do guia, tanto na validação de conteúdo quanto na validação de aparência, as notas alcançaram uma pontuação superior a exigida. O guia foi validado em conteúdo e aparência, estando apto para avaliação com público-alvo. Para futuras pesquisas, sugere-se a construção de estudos qualitativos na construção de um guia digital que trate o cuidado inicial e validação externa.
