Reinforced with Titanium Dioxide and Silicon Carbide
Authors: Ravi Raj V. , Dhivya Praban S. V. , Jayasooriya M. , Sairam T. S.
Published: September 2024

Metal matrix composites (MMCs) have evoked a keen interest in recent times for
their potential applications in automotive and aerospace industry components.
One such particulars include dry sliding bearings, which have widespread
applications in various industries due to their self-lubricating properties,
high wear resistance, and low maintenance requirements. The wear as a
consequence of metal-to-metal friction can have a detrimental effect, expediting
malfunctions or much more adverse spin-offs on the whole system. This study
focuses on the development and characterization of a novel dry bearing material
composed of a MMC consisting of aluminum (Al), titanium dioxide
(TiO2), and silicon carbide (SiC). Tribological tests revealed a low
friction coefficient, ensuring efficient and reliable operation. The results
indicate the enhancement of MMC’s performance and durability in dry bearings,
contributing to the efficiency and reliability of engineering systems. The study
not only highlights the material’s potential but also opens opportunities for
advanced, self-lubricating bearing materials, emphasizing the importance of
material design in advancing engineering technologies.

Published: September 2024

Mauritius raspberry (Rubus rosifolius) is an exotic plant cultivated in Indonesia. Studies showed that the productivity of exotic plants is reducing due to a lack of pollination agent for their origin region. Several methods could be applied to overcome this problem. The study aimed to find the most effective method for pollinating this plant among four pollination regimes: Self-pollination, wild insects, stingless bees (Tetragonula laeviceps), and hand-pollination. The observation was conducted on the insect pollinators' activities (visitation rate, flower constancy, and flower handling time), pollination efficiency, and quality of the fruits produced (fruit volume). The results showed a higher visitation rate (10 to 70 per hour), higher flower constancy (visited from 07.00 to 16.00), and longer flower handling time (13.6 s) of T. laeviceps on raspberry flowers than other insects. High activities related to better raspberry pollination success (96%) and bigger fruits produced. Based on this study, applying stingless bees as pollination agents for exotic plants was the best and potentially applicable to other exotic crops.

Stingless bees (Apidae: Meliponinae) are distributed in the tropics, and there are more than 600 species worldwide, Forty-six species were recorded in Indonesia. Nest of the species is generally found in tree holes, rocks, house walls, house wooden, bamboo cavities, and soil. Current research explores the species richness, nesting sites and morphometry of stingless bee species in the forest and settlement areas in Banten province, Indonesia. Road- and purposive sampling methods were used to explore the stingless bee species. Thirty-five body characters of each stingless bee species were measured. Results showed four stingless bee species found were Tetragonula laeviceps, Heterotrigona itama, Lepidotrogona terminata, and Tetragonula sp. The dominant species found was L. terminata in the forest, while T. laeviceps in the settlement areas. The nesting sites of stingless bees in the forests were found in the tree cavities of various plant species with tree diameter range 39.3-87.3 cm. In contrast, the nest of T. laeviceps was found in the tree of Swietenia mahagoni, Lansium parasiticum, and bamboo cavities of houses in the settlement areas. The nest entrances of stingless bees varied, i.e., oval-rounded, tubular with varied diameters, and blackish-brown in color. The internal structure of the nest consists of brood cells, pollen cells, and honey cells. Heterotrigona itama has the largest body size (5.52 mm in length), followed by L. terminata (4.99 mm in length) and T. laeviceps (3.86 mm in length). Thirty-three characters of H. itama were larger than L. terminata and T. laeviceps, except for gena width and malar length.

Published: September 2024

The crowing of male Gallus exhibits diverse sound patterns. This is believed to be related to the phenotypic diversity of vocal organs, one of which is influenced by the nucleotide diversity of the associated genes. The SOX9 gene, involved in cartilaginous tissue growth and development, is reported to contribute e in the development of larynx and syrinx. This study aimed to characterize the CDS regions of exons 1 and 2 of the SOX9 gene in junglefowl to assess its diversity. Genomic DNA was extracted from ten individuals of G. varius from Lombok and Sumbawa. The CDS regions of SOX9 gene exons 1 and 2 were amplified using two primer pairs. Additionally, the CDS regions of SOX9 gene exons 1 and 2 from 54 junglefowl SRA data in an online repository were mapped and analyzed. The study identified all nucleotide sequences as CDS regions of SOX9 gene exons 1 and 2. Six shared, and 24 unique haplotypes were constructed. A putative amino acid sequence common to all Gallus species was also identified. The diversity observed in the CDS regions of SOX9 gene exons 1 and 2 nucleotide sequence showed a diﬀerent level with the diversity observed in its amino acid sequence.

Alpinia monopleura is one of the endemic plants of Sulawesi, and it has an extensive distribution in the region. Research on chemical compounds and biological activities of A. monopleura is essential to continue as an effort to support the utilization of native plants for medicine. The extract was obtained using the maceration method. The chemical compounds in the extract were identified using Liquid Chromatography Mass Spectrometry (LCMS). Bovine Serum Albumin (BSA) and molecular docking methods were used to evaluate the anti-inflammatory activity. Ten compounds contained in the extract were successfully identified, E-para-coumaric acid (1), trans-ferulaldehyde (2), 3,5,6-trihydroxy-4',7-dimethoxyflavone (3), nevadensin (4), malvalic acid (5), ent-16α,17-hydroxy-19-kauranoic acid (6), 3′,5-dihydroxy-7,4'-dimethoxy flavone (7), saurufuran B (8), 5-hydroxy-7,8,2'-trimethoxyflavanone (9) and dehydroabietic acid (10). The anti-inflammatory activity of extracts from rhizomes and stems of A. monopleura were 8.62 and 10.59 mg/L, respectively. Some flavonoids (9 and 7) can bind strongly to specific residues around the COX-2 active site, such as Ser530, thereby interfering with the function of the COX-2 enzyme and reducing the production of pro-inflammatory prostaglandins. Thus, A. monopleura extract has the potential to inhibit inflammatory responses through molecular regulation of the COX-2 enzyme.

Published: September 2024

Infectious Bursal Disease (IBD) is an infectious and immunosuppressive disease primarily affecting young chickens. Despite stringent biosecurity and vaccination for control measures, the effective management of IBD remains challenging. The disparity in observed clinical symptoms in the field infections further complicates matters for breeders. The study aims to perform molecular characterization of VP2 gene fragments to identify the latest genotype of field IBD viruses. Twenty-two samples of bursa of Fabricius were collected from broilers suspected of IBD in commercial farms located in Central Java and The Yogyakarta Special Region from 2021 to 2022. Viral RNA was extracted from these samples, and after amplification, a 743 bp PCR product was obtained and subjected to sequencing. The obtained sequences were analyzed in Mega X for multiple alignments, amino acid prediction, homology, and phylogenetic tree construction. Lesion, i.e., Bursa of Fabricius enlargement, oedema, swelling of plica bursa, gelatinous mass, hemorrhage, atrophy, and thigh muscles petechiae to hemorrhage, were considered indicative of IBD. Out of 22 samples tested by RT-PCR, 19 were positive, and 13 samples were selected for sequencing. All sequenced samples belonged to Genogroup A3, specifically the very virulent IBD (vvIBD) strain.

Duckweed, a widely used natural fish feed, has also become more popular as the phytoremediation agent for wastewater, including one sourced from aquaculture. These two features indicate that duckweed can be utilized in a sustainable aquaculture system by treating and reclaiming nutrients from wastewater and then harvesting them for fish feed production. Hence, this study attempted to assess the approach of the two most known duckweed species, i.e., Lemna minor and Spirodela polyrhiza, in depleting NH4 and PO4 from synthetic controlled aquaculture wastewater as well as to understand their yield based on the N : P ratio. Cultivation in synthetic aquaculture wastewater media was carried out, followed by nutrient uptake and growth analysis. According to statistical analysis, both L. minor and S. polyrhiza could remove NH4 and PO4 with a relatively equal rate (p-val > 0.050). Nonetheless, both duckweed species absorb nitrogen more easily than phosphorous (p-val < 0.050). Considering the yield based on nutrient uptake, NH4 drove a more efficient yield for L. minor to S. polyrhiza at 16.70 g dry biomass/g NH4 and 14.14 g dry biomass/g NH4, respectively. Meanwhile, a higher yield was observed on S. polyrhiza than on L. minor regarding PO4 concentration, at 19.31 g dry biomass/g PO4 and 9.10 g dry biomass/g PO4, respectively. Therefore, a strategy to remove nutrients and produce biomass for fish feed can be formulated based on the N : P concentration ratio, where L. minor tends to produce biomass more rapidly in a higher N : P ratio, whereas S. polyrhiza works in the opposite.

Published: September 2024

Pro- and anti-inflammatory mediators need to be released in a balanced way to maintain a healthy state as we age. One important regulatory element in the equilibrium of pro- and anti-inflammatory mediators is NF-κB. The purpose of this study was to examine how S. platensis affected the control of inflammatory mediators in young, healthy, emerging adults and adults in rats. In this investigation, 200 mg/kg BW of S. platensis extract was administered to six groups of male Wistar rats, ages 12, 18, and 24 weeks, along with a control group. In both the treatment and control groups, NF-κB p65 protein expression was lower at 24 weeks than it was at 12 and 18 weeks. TNF-α and COX-2 proteins were lower in the treatment group than in the control group. All age groups in the treatment group had higher levels of IL-10 protein than the control group. The quantity of NF-κB p65 was positively correlated with COX-2 and TNF-α. By raising the concentration of NF-κB p65, the ethanolic extract of S. platensis altered a mediator of cellular immunity. A decrease followed this in TNF-α and COX-2 and a rise in IL-10 in the rat spleen at different ages.

Girondo: la materialización del ritmo
Authors: Monteleone Jorge
Published: September 2024

Es un lugar común de la crítica señalar que Oliverio Girondo es un poeta visual. Sin duda es una conclusión irrefutable y puede comprobarse en las pinturas del poeta y en la composición misma del libro-objeto Veinte poemas para ser leídos en el tranvía. Sin embargo, en este artículo exploramos un aspecto suplementario, que se hace evidente en el análisis del célebre caligrama “Espantapájaros”. Se trata de una espacialización del ritmo. El caligrama de Girondo simula un cuerpo unificado en su figuración icónica, pero desmembrado al decirlo como poema. Como señala Henri Meschonnic, los caligramas son “vectorizaciones dinámicas que actualizan gráficamente el decir”. El sentido de “Espantapájaros” en la tipografía consta de una espacialización evidente a simple vista, pero además consta de una rítmica material, ideogramática, situada entre el ritmo oral y el ritmo tipográfico. La lectura de los poemas de En la másmedula y la consiguiente oralización en la grabación discográfica del propio Girondo en los años sesenta, refuerzan esta dimensión rítmica de su poética. La oralización de En la masmédula no supone una mera versión sonora, sino un acto culminante: la final materialización del ritmo oral en la voz, derivada de una espacialización del ritmo. No hay significado en esa dicción materialista del ritmo, sino significancia: el sentido en su despliegue sensorial y el espacio en su profundidad prosódica. El poema como unidad del sentido, y no el verso. Esa sería la finalidad del proyecto poético de Girondo: concretar la materialización del ritmo en la doble dimensión espacial y temporal.
Puesta en abismo para reconstruir el reino. Diálogo entre lo verbal y lo visual en Miguel Ángel Bustos
Authors: Arancet Ruda María Amelia
Published: September 2024

En el presente trabajo analizamos el diálogo entre los códigos verbal y visual en El Himalaya o la moral de los pájaros (1970), último libro del argentino Miguel Ángel Bustos (1933-1976). Postulamos que los dibujos que el autor incorpora no son meras ilustraciones, sino que integran el tejido del relato aportando información y niveles de lectura que lo puramente verbal no dice. Para su realización recrea mitos de origen y de destino de distintas tradiciones. Aquí solo sopesamos la europea de la época de la Conquista y la precolombina de los principales pueblos originarios. Hallamos que, en su vasta erudición, emulando códices el creador confronta tales acervos, los cuestiona y los hace abrirse a nuevos efectos de sentido y a temporalidades superpuestas. Un motivo central del análisis es el libro como objeto. Ante la vista de estos procedimientos hallamos que hay una estructura que explica desde el mecanismo del detalle hasta la obra entera: la puesta en abismo. Teniendo en cuenta el resto de sus libros anteriores explica la poética propia de nuestro autor.

Todos es siempre ahora” que tuvo lugar en el Centro Cultural Borges de la ciudad de Buenos Aires entre el 19 de diciembre de 2013 y el 21 de enero de 2014. Ese día la muestra fue levantada intempestivamente a raíz del robo de uno de los cuadros expuestos. El artículo, que tiene su origen en una nota publicada en el diario argentino Página/12 con motivo de los diez años de aquella muestra, intenta un análisis del catálogo y de algunos aspectos conceptuales sobre la convergencia temporal/espacial de la obra poética de Miguel Ángel Bustos y Emiliano Bustos, padre e hijo respectivamente.
Arcontes de pacotilla: algunas ideas sobre el concepto de archivo y América Latina
Authors: Herzovich Guido
Published: September 2024

En las últimas décadas el concepto de archivo se ha vuelto cada vez más ubicuo y transdisciplinario: de la filosofía o la antropología a la crítica sobre todas las artes. ¿A qué se debe esta proliferación? ¿Es posible hacer de esta moda un camino de indagación sobre la situación contemporánea de las artes o de la crítica? Este artículo, deudor de un proyecto de investigación colectivo, parte de dos hipótesis. En primer lugar, que hoy a menudo decimos “archivo” donde hace algunas décadas hubiéramos dicho “tradición” y que ese reemplazo permite pensar cómo se han transformado las exigencias y fantasías que depositamos sobre el arte y la literatura. En segundo lugar, que el declive del concepto de tradición coincide en América Latina con la derrota política y militar de los movimientos emancipatorios de los años sesenta y setenta.
Reflejos de vanguardia: la guerra al nervio óptico entre Macedonio Fernández y Jorge Luis Borges
Authors: García Mariano
Published: September 2024

La figura excéntrica de Macedonio Fernández ha llamado la atención por las afinidades de su estética “asensorial” o Belarte con la propuesta “antirretiniana” y la “belleza de indiferencia” de Marcel Duchamp. A partir de este vínculo entre dos vanguardias que por muy poco no se cruzaron, analizaremos algunas constantes de la poética de Borges, en particular su relación con metáforas obsesivas como los espejos y su corolario, la simetría. Para ello tomaremos como base el ensayo de Martin Jay Downcast Eyes, a fin de establecer un paralelo entre la tradición francesa “antiocular” y el contexto argentino de la primera mitad del siglo XX.

Published: September 2024

La esclerosis tuberosa, también conocida como síndrome tuberculoso (CET), es una enfermedad genética rara con una incidencia global de 6,4 a 12,4 casos por cada 100.000 habitantes. El pronóstico de los individuos con CET viene determinado por la gravedad de sus síntomas. Los síntomas menos graves conducen a una vida más larga y productiva, mientras que los más graves pueden causar discapacidades graves. Actualmente no existe cura para la CET. Este texto presenta un estudio de caso clínico sobre CET, detallando su definición, tratamiento, factores de riesgo y hallazgos. A un paciente de 17 años se le diagnosticaron desde los tres años diversos síntomas, entre ellos fibromas de Koenen, fibromas gingivales, quistes hepatocelulares, angiomimpomas renales, gliosis cerebral y magna megacisterna. A pesar de cumplir los criterios diagnósticos, no se han realizado estudios genéticos debido a limitaciones financieras. Los expertos en la materia deben tener amplios conocimientos de la gran variedad de síntomas de los pacientes con CET. La vigilancia y la intervención rápida desempeñan un papel crucial en la promoción de un pronóstico más favorable y la prevención de complicaciones. La vigilancia permanente de los profesionales sanitarios es esencial para un diagnóstico preciso y un tratamiento oportuno.

AUSTRIAN STATE ARCHIVES AND ITS HOLDINGS RELATING TO GROSS-BETSCHKEREK: A GOOD EXAMPLE OF ONLINE SEARCH TOOLS
Authors:   Istorijski arhiv Zrenjanin, Srbija, Krčmar Filip
Published: September 2024

The Austrian State Archives, which was founded in 1945, are now con- sidered the central and main archive of the Republic of Austria. Its establishment end- ed a process of centralization and integration of various archives that had existed for decades. The newly established archive included the War Archives, Finance and Court Archives, as well as the House, Court and State Archives, to which the General Admin- istrative Archives and Archive of the Republic were later added. The article first provides a general overview of the founding of the archive and each of its departments; then the content of the exemplary and organized web presentation of the Austrian State Archives (oesta.gv.at) is analyzed, i.e. its segments that offer visitors detailed information about the archive, its holdings, organizational structure, history, etc. The text then focuses on the diverse online research modalities and searches of the archives. These include the following search types: full-text, archive plan and field search, each of which is explained individually. Using them enables an exact location and specialist description of the ar- chival materials relating to the places in today’s Serbia. As an example, the archival assets relating to the former Gross-Betschkerek (today: Zrenjanin) are shown, which include around 30 different individual items, plans, documents and other types of archives. Mainly kept in the house, court and state archives, they are of inestimable importance for the local history of Gross-Betschkerek, whose gaps are partially filled with them. Since the Historical Archives in Zrenjanin was almost robbed of archival materials from the 18th century, their importance is all the greater. Finally, the article demonstrates not only the similar search results for other cities and localities in today’s Serbia, but also for the important personalities and events from Serbian national history. For each larger town, the exact (current) number of relevant archival documents was given, taking into account the different spellings of their names in German. Famous historical figures were illustrated by the example of Serbian champions in southern Hungary and Serbian rulers from the two national dynasties (Karadjordjevic and Obrenovic). Finally, the Austrian State Archives were described as a rich research source, from which local historians and researchers have made little use, and where a little-known but valuable factual quantity is kept. Its contents still await serious and conscientious documentation, evaluation, re- search and use by Serbian archivists, historians and other researchers.

AVIATION MILITARY CEMETERY IN NOVI SAD
Authors:   Archives of Vojvodina, Serbia, Jaćimović Miroslav , Radaković Željko ,   Archives of Vojvodina, Serbia
Published: September 2024

This work contains a brief history of air traffic and the aviation indus- try in Novi Sad, and deals with the topic of pilots that were buried here at the aviation cemetery in Novi Sad from 1918 to 1941 during the Kingdom of Yugoslavia. Novi Sad had been known as a center for aviation activity for a long time after the Great War, and this reputation continued after an airport was placed in the present-day Jugovićevo urban neighborhood so that it could be used by the military of the Kingdom of Serbs, Croats and Slovenes. Novi Sad and Petrovaradin also became centers of education for pilots, and even a factory called Ikarus was opened. Unfortunately, military service can be hard and deadly, and so 56 heroes found their eternal resting place in this area of Novi Sad which is today located at the edge of Vojvoda Knićanin Street and Futoška Street. Among the pilots, the most famous ones were of course Jovan Jugović, after whom the airport got its name later on, Josip Antunović, Živan Popović, Josif Križman, and the first Yugoslav that carried out a parachute jump, Dragutin Dolanski, at the height of 650 m, as well as Antun Šimunović and other pilots. This work is mostly the result of the research that was carried out at the cemetery itself, and is supported with photographs, with the ultimate goal of publishing a monograph on this topic. The area of the aviation cemetery was declared a cultural heritage of great importance.
THE ROLE OF EXPLICIT INSTRUCTION IN DEVELOPING ENGLISH LEARNERS’ MULTIMODAL LITERACY
Authors: Tirizite Youssef , Marjane Driss
Published: September 2024

In today's context, successful communication requires individuals to grasp, engage with, and construct multimodal texts in various formats. The creation of knowledge artifacts is central to developing multimodal literacy and communicative competence. This action research study sought to investigate the influence of explicit instruction on enhancing students’ overall semiotic awareness. A multi-dimensional instructional model was tested for its effectiveness, with students' feedback serving as the primary evaluative tool. The study sample consisted of sixteen students, comprising seven males and nine females, all aged 17 or 18 years. A post-instruction questionnaire was conducted to collect students' reflections and feedback on the strategies used during the class session. The intervention lasted approximately two hours. Data from the qualitative questionnaire reported a high level of affective and cognitive engagement. The findings also indicated a noticeable increase in students’ overall semiotic awareness due to explicit instruction. These results could serve as a foundation for refining and implementing instructional methodologies that continue to empower students in their understanding and utilization of multimodal communication in diverse contexts.

Published: September 2024

Neighborhood crimes have been one of the major problems worldwide, and it is getting worse as time goes by. This study aims to determine the effectiveness and impact of police visibility as a crime prevention tool for neighborhood crimes in selected barangays in Davao City. The research has utilized quantitative research and survey methods in the performance of this study as a tool for collecting data. The researchers utilized an adapted questionnaire from the study of España & Nabe (2023), A Scale Development on Neighborhood Crime in Davao City: An Exploratory Factor Analysis, and a study by Borovec et al. (2019), Police Visibility as an Influencing Factor on Citizens' Perception of Safety. Research was conducted on 300 random participants from districts 1, 2, and 3 in Davao City. The statistical tools employed in understanding the data gathered are Descriptive Statistics, Spearman’s Rho, and Multiple Regression Analysis. The findings show that the increase in police visibility is associated with reduced occurrences of social disorder, social disorganization, and breakdown of social control. The result of this study found that the overall mean of neighborhood crimes is 3.17 with a standard deviation of 0.59, which indicates an average mean level; it shows that the residents do not feel completely safe in their neighborhood due to the uneven distribution of safety perception. Thus, to promote a safer environment, the community should work and build strong relationships with their neighbors and police officers.

Synchronization of chaotic oscillator systems based on adaptive synergetic control theory
Authors: Saadi Salah Eddine , Behih Khalissa , Bouchama Ziyad , Essounbouli Najib , Zehar Khaled
Published: September 2024

In this study, adaptive terminal convergence using robust synergetic control theory and finite-time attractor algorithms is explored to achieve synchronization and anti-synchronization between two different chaotic oscillator systems, while considering system uncertainties and external disturbances. To render the controller more robust and enable it to handle the nonlinear terms of the synchronized error system and to be easily implementable even when the bounds of system uncertainties and external disturbances are unknown, an adaptive control gain law derived from Lyapunov stability analysis is incorporated into the controller design. Numerical simulations are conducted to validate the proposed adaptive finite-time synergetic controller (AFSC) scheme. These simulations demonstrate that the AFSC outperforms the conventional adaptive synergetic controller (ASC) design by achieving more effective synchronization and anti-synchronization. The AFSC exhibits superior robustness, handling a wider range of system conditions and disturbances, making it practical for real-world scenarios where precise knowledge of system dynamics is often unavailable.

Published: September 2024

Fish individual fecundity is an important factor governing fish replenishment and population dynamics. An in-depth understanding of the dynamics of fish fecundity is not only important for the study of fish and fisheries ecology but also of great practical significance. From mid-February to early March 2023, we collected 99 samples of Hemibarbus medius in the Beiliu River and analyzed their body length, body weight, empty shell weight, and gonadal weight. Using the weighing mass method, we calculated the absolute fecundity of each individual, relative fecundity in terms of the body length and weight, gonadosomatic index, and Fulton’s condition factor. We used six mathematical models to fit the relationship between individual fecundity and the biological indicators of H. medius. The study demonstrated that the female-to-male ratio in the samples was 1.06:1, and the minimum age for sexual maturity was observed as 1+ and 0+ years old for females and males, respectively. Furthermore, the body lengths of females with gonadal development of stage IV or above ranged from 11.5 to 25.7 cm, while their body weights ranged from 24.04 to 263.42 g. The absolute fecundity of individuals varied significantly, ranging from 195 to 14,044 eggs. The relative fecundity of the lengths was between 17 to 624 eggs/cm, while the relative fecundity of the body weights ranged from 5 to 76 eggs/g. This study established that absolute fecundity exhibits power function correlations with various biological indicators except for parabolic correlation with Fulton’s condition factor of H. medius, whereas body length relative fecundity demonstrates power function correlations with all biological indicators except parabolic correlations with empty shell weight and Fulton’s condition factor. Notably, body weight relative fecundity displays significant correlations only with the gonadosomatic index. These findings are crucial in accurately estimating the population size of H. medius in Beiliu River and its change pattern. In addition, these findings provide a foundation for resource management and rational utilization of H. medius in the Beaulieu River.
Drogen in der Klinischen Analytik: Katz-und-Maus-Spiel: Nachweisbarkeit des Drogenkonsums
Authors: Koch Katharina
Published: September 2024

Die Nachweisbarkeit eines Drogenkonsums hängt von der konsumierten Substanz, der Dosis sowie der zur Unter­suchung verwendeten Matrix und Nachweismethode ab. Eine besondere Herausforderung für die Labore stellen neue Drogen wie synthetische Cannabinoide dar. Erschwert wird die Analytik und die Interpretation der Messergebnisse auch dadurch, dass es sich bei manchen Vertretern der verschiedenen Wirkstoffgruppen um handelsübliche Medikamente handelt.
Medikamenten-Intoxikationen in der Klinischen Analytik: Therapeutische Dosierung oder behandlungsbedürftige Intoxikation?
Authors: Jungen Hilke , Meyer Markus R.
Published: September 2024

Zu den häufigsten Vergiftungen mit Medikamenten gehören Intoxikationen mit Paracetamol, Benzodiazepinen und trizyklischen Antidepressiva. Zur Beurteilung der Schwere der Vergiftung können – neben der Symptomatik der Betroffenen – chemisch-toxikologische Untersuchungen von Urin- und Blutproben wichtige Hinweise geben. Insbesondere bei Paracetamol-Vergiftungen werden auch auf Basis des Substanznachweises Entscheidungen hinsichtlich einer möglichen Antidot-Therapie getroffen. Neben immunchemischen Untersuchungsmethoden kommen für eine eindeutige Identifizierung und Quantifizierung der jeweiligen Wirkstoffe vor allem chromatographische Verfahren zum Einsatz.
Nachweis und Wirkung von K.-o.-Mitteln: Ist nach zwölf Stunden nichts mehr zu finden?
Authors: Andresen-Streichert Hilke , Stach Paul , Szewczyk Anne

Als K.-o.-Mittel werden Substanzen bezeichnet, die meist ohne das Wissen der Person, die sie aufnimmt, verabreicht werden und die die Handlungs- und Widerstandsfähigkeit negativ beeinflussen können. Als Substanzen kommen – neben den klassischen Vertretern wie Gamma-Hydroxybuttersäure und Benzodiazepinen – eine große Anzahl weiterer zentral dämpfender Medikamente und besonders Alkohol in Betracht. Auch eine unbeabsichtigte Wechselwirkung bzw. Wirkpotenzierung durch Alkohol kann eine Rolle spielen. Die Nachweisbarkeitsdauer ist – abhängig von der Substanz und ihrer Halbwertzeit – (sehr) kurz, sodass bei Verdacht eine zeitnahe Probenabgabe extrem wichtig ist. Vor allem muss Urin asserviert werden, da hier das Nachweisfenster größer ist. Eine umfangreiche und sensitive Analytik sollte in einem dafür spezialisierten Labor durchgeführt werden.

The presidential threshold is a rule that becomes a political requirement for a political party to carry presidential and vice presidential candidates. The existence of this rule can potentially cause restrictions on citizens in running for president and restrictions on political parties in carrying their candidates to the presidency and vice presidency. The presidential threshold journey in coloring the elections in Indonesia has also undergone material testing and a lawsuit by the Constitutional Court. Therefore, this study aims to discuss the practice of the Presidential threshold in the implementation of elections in Indonesia and its relation to the political rights of citizens and political parties in Indonesia. This study is a field research study with a study into the field and using a non-doctrinal approach that is the enactment of law. Primary Data was obtained by interview techniques to the KPU RI, political parties, and legal experts. Furthermore, the secondary data consists of primary, secondary, and tertiary legal materials. This legal research uses descriptive analysis to obtain research results. The results showed that the practice of Presidential threshold has existed since the enactment of the first presidential and vice presidential elections. The political rights of citizens and political parties do not necessarily disappear, they only become conditional. Political parties also have the same opportunity to nominate the president and vice president by carrying their own or joining and forming coalitions with other parties.

This study explores the management of a pesantren-based Madrasah Aliyah (MA) curriculum in Purbalingga Regency, focusing on the integration of traditional pesantren values with contemporary educational needs. As the global landscape evolves, there is a pressing need to balance the preservation of Islamic identity with the demands of a pluralistic society. The study addresses this by examining how pesantren traditions can be harmonized with modern educational requirements. The development of a pesantren-based curriculum in Madrasah Aliyah is deeply rooted in the rich tradition of Islamic education and traditional sciences that pesantren embody. However, aligning this curriculum with contemporary advancements and broader societal needs presents a significant challenge. This study aims to analyze how traditional values can be effectively integrated into a modern educational framework, ensuring that students are well-prepared for both religious and worldly challenges. The research employs management theories as proposed by Curtis R. Finch, John R. Cruncilton, and Terry, to guide the processes of planning, implementing, supervising, and evaluating the pesantren-based curriculum. A case study was conducted in three pesantren-based MA institutions in Purbalingga Regency, specifically at MA Nurul Barokah Bojongsari Purbalingga. The study utilizes qualitative methods, including curriculum analysis, observations, and interviews to gather data on how pesantren values are incorporated and how the curriculum adapts to modern educational needs. Key findings reveal that integrating pesantren values with contemporary educational approaches results in a more holistic educational model that retains traditional Islamic teachings while addressing modern demands. The study highlights the effectiveness of combining traditional methods with innovative practices and underscores the importance of rigorous supervision and continuous evaluation to ensure curriculum effectiveness. This research provides valuable insights into how pesantren-based Madrasah Aliyah curriculum management can offer a robust model for Islamic education in Indonesia. It offers practical implications for developing educational strategies that respect traditional values while adapting to current and future educational needs.

In the current digital era, ICT use in the classroom is important for giving students opportunities to learn and apply the required skills. Therefore, this study sought to identify the level of ICT tools’ accessibility by O’ Level students in government secondary schools in Mbale District. A quantitative research design was used to collect the data from a sample of 192 that included school head teachers, teachers and students. Overall, the key challenges found identified in using ICT tools were: lack of access to laptops, printers and computer laboratories, projectors and screen. This poor accessibility was due to; high student-computer ratio, unreliable power supply, lack of trained ICT personnel, lack adequate funding for ICT tool procurement and maintenance, inadequate administrative support, limited time for practice, and unstable and slow internet. The results show that students in the study area were not easily accessing the necessary ICT tools and this had a significant relationship with the implementation of the O’ Level ICT curriculum. It is recommended that the responsible education stakeholders enhance increased student access to ICT tools.
