Authors: Kim Jeong Yeon , Jeong Yujin , An Hyonggin , Suh Jin Woong , Sohn Jang Wook , Yoon Young Kyung
Published: March 2024

Background: We aimed to compare the epidemiological and clinical
characteristics of coronavirus disease 2019 (COVID-19) in people living
with human immunodeficiency virus (HIV) (PLWH) with those in the general
population. Methods: This nationwide descriptive epidemiological study
was conducted in South Korea between January 2020 and February 2022. The
National Health Insurance claims data covering the whole nation were
collected through the Health Insurance Review and Assessment Service.
Results: Among 3,653,808 individuals who were diagnosed with COVID-19,
1,311 (0.04%) were PLWH. All the PLWH received antiretroviral therapy,
and 26.47% had more than one underlying disease other than HIV
infection. The overall in-hospital mortality rates of PLWH and the
general population were 0.76% and 0.25%, respectively (P=0.002).
According to the Cox proportional hazard model, no significant
difference was observed in the in-hospital mortality rate [hazard
ratio (HR): 1.80, 95% confidence interval (CI): 0.70–4.67] between
PLWH and the general population. However, progression to severe or
critical COVID-19 was more common in PLWH (HR: 2.70, 95% CI:
1.37–5.33). In PLWH diagnosed with COVID-19, a multivariable Cox
regression analysis found old age (≥60 years old) (HR: 6.9; 95% CI
2.57–18.56) and diabetes mellitus (HR: 5.13; 95% CI: 2.02–13.00) as
the independent risk factors for severe or critical COVID-19.
Conclusions: PLWH had a significantly higher risk of severe or critical
COVID-19 than that of the general population. Our findings suggest the
need for applying differentiated strategies to decrease the impact of
COVID-19 on PLWH.
Multimodal Measurement of Apoptosis -- Integration of Biosensing, Imaging, and Analysis

Published: March 2024

Apoptosis is a highly regulated form of cell death. Currently, the
established methods for apoptosis detection include observation of cell
morphology and probing of DNA fragmentation. These methods focus on the
detection of changes that occur later in the apoptotic process.
Nevertheless, detection of apoptosis at the early stages, prior to gross
morphological changes, is critical for understanding the entire
apoptotic pathway and for providing the possibility to intervene and
enhance longevity and productivity of cell cultures used to produce
biologicals. A group of proteases known as caspases act together in a
cascade to cleave proteins at aspartic acid residues. This proteolytic
cascade amplifies the apoptotic signalling pathway and thus leads to
rapid cell death. In this paper, an impedance spectroscopy technique
using non-Faradaic measurement of caspase-9 was combined with
fluorescence-based light microscopy including an associated macro-based
image analysis suite for ImageJ in a multimodal approach. Whereas the
biosensor measurements provide a cell population overview, the
microscopic analysis provides individual cell analysis. Combined, these
approaches allowed us to detect cells in the early stages of apoptosis
in the cell population. We believe these complementary methods will
allow us to follow the progression of apoptosis in cells more accurately
and give us a handle to intervene at early stages of apoptosis.
Contribution of Western Arabian Sea Tropical cyclones to rainfall in the Horn of Africa
Authors: Camberlin Pierre , Assowe Omar , Pohl Benjamin , Waberi Moussa Mohamed , Hoarau Karl , Planchon Olivier
Published: March 2024

The occurrence of tropical cyclones (TC) in the Horn of Africa and
nearby areas is for the first time examined to document their
contribution to local rainfall and their trends over the period
1990-2020. An average 1.5 TC (of any intensity) per year was observed
over the Western Arabian Sea, with two asymmetrical seasons, namely
May-June (30% of cyclonic days) and September-December (70%). Case
studies reveal that in many instances, TC-related rainfall extends
beyond 500 km from the TC center, and that substantial rains occur one
to two days after the lifecycle of the TC. Despite their rarity, in the
otherwise arid to semi-arid context characteristic of the region, TCs
contribute in both seasons to a very high percentage of total rainfall
(up to 30 to 60%) over the northwestern Arabian Sea, the Gulf of Aden
and their coastlines. Over inland northern Somalia, contributions are
much lower. TCs disproportionately contribute to some of the most
intense daily falls, which are often higher than the mean annual
rainfall. A strong increase in the number of TCs is found from 1990 to
2020, hence their enhanced contribution to local rainfall. This increase
is associated with a warmer eastern / southern Arabian Sea, a decrease
in vertical wind shear, and a strong increase in tropospheric moisture
content.

Published: March 2024

Development research was conducted to create a science comic product about how the body reacts to light. The comic aims to address common misconceptions that students have about the subject of light. The science comic teaching materials about light were designed to cater to the needs of fifth-grade students in elementary schools. The development research method used was ADDIE (Analyze, Design, Development, Implementation, Evaluation), with 43 class V UPT students at SD Negeri 18 Gresik participating. The analysis involved needs analysis, material analysis, and analysis of learning implementation. The designs were produced using Photoshop CC & Corel Draw X7 software, and the development stage involved turning the designs into a comic product. Validation was conducted by validating appearance, material, and language, with each validation involving two validators. Implementation was carried out using the PBL learning model, and the results were 100% in the very effective category. Evaluation was also conducted by providing student response questionnaires, and the results were 90.7% in the very good category. The research produced a valid science comic with a score of 87.74% in the very valid and 100% effective category. So it is recommended that further research can develop more open science comic materials for elementary school students on various interesting topics and by the curriculum to increase students' interest in learning about natural science.

Décès accidentels attribuables à une intoxication aiguë due à une substance chez les jeunes au Canada : analyse descriptive d’une étude nationale portant sur l’examen des dossiers des données de coroners et de médecins légistes
Authors: Chang Grace Yi-Shin , VanSteelandt Amanda , McKenzie Katherine , Kouyoumdjian Fiona
Published: March 2024

Introduction

Les décès attribuables à une intoxication aiguë due à une substance sont à l’origine d’une crise de santé publique au Canada. Les jeunes courent souvent un risque accru de consommation de substances en raison de facteurs sociaux, environnementaux et structurels. Les objectifs de cette étude étaient de comprendre les caractéristiques des jeunes (12 à 24 ans) qui décèdent en raison d’une intoxication aiguë accidentelle au Canada ainsi que d’analyser les substances qui contribuent aux décès par intoxication aiguë chez les jeunes et les circonstances entourant ces décès.

Méthodologie

Nous avons utilisé les données d’une étude nationale portant sur l’examen des dossiers des données de coroners et de médecins légistes concernant les décès par intoxication aiguë survenus au Canada en 2016 et 2017 afin de réaliser des analyses descriptives à partir des proportions, des taux de décès et des taux proportionnels de décès. Dans la mesure du possible, les jeunes faisant partie de l’étude sur l’examen des dossiers ont été comparés, au moyen de données de recensement, aux jeunes dans la population générale et aux jeunes décédés toutes causes confondues.

Résultats

Sur les 732 jeunes décédés par intoxication aiguë accidentelle en 2016-2017, la plupart (94 %) avaient entre 18 et 24 ans. Les jeunes de 20 à 24 ans sans emploi et vivant dans un logement collectif ou sans domicile étaient surreprésentés parmi les décès accidentels par intoxication aiguë. Parmi les jeunes de 12 à 24 ans décédés en raison d’une intoxication aiguë accidentelle, beaucoup avaient des antécédents documentés de consommation de substances. Le fentanyl, la cocaïne et la méthamphétamine ont été les substances ayant le plus fréquemment contribué aux décès, et 38 % des décès ont eu lieu en présence d’un témoin ou potentiellement en présence d’un témoin.

Conclusion

Les résultats de cette étude soulignent la nécessité de mettre en place des mesures de prévention précoce, des stratégies de réduction des méfaits et des programmes portant sur la santé mentale, l’exposition à un événement traumatisant ainsi que le chômage et l’instabilité résidentielle, afin de réduire les méfaits de la consommation de substances chez les jeunes Canadiens.
Décès accidentels liés à une intoxication aiguë due à une substance chez les aînés en 2016 et en 2017 : une étude nationale d’examen des dossiers
Authors: VanSteelandt Amanda , Ha Jingru Helen , Burt Jacqueline , Randell Shane
Published: March 2024

Introduction

Il existe peu de recherches sur les décès liés à une intoxication aiguë due à une substance chez les aînés (60 ans et plus) au Canada. Cette étude vise à explorer et à décrire les caractéristiques sociodémographiques, les antécédents en matière de santé et les circonstances des décès en ce qui concerne les décès accidentels liés à une intoxication aiguë chez les aînés.

Méthodologie

À la suite d’une analyse descriptive rétrospective de tous les dossiers des coroners et des médecins légistes sur les décès accidentels liés à une intoxication aiguë due à une substance chez les aînés au Canada de 2016 à 2017, les pourcentages de décès et les taux de mortalité issus des données des coroners et des médecins légistes ont été comparés aux données sur les aînés de la population générale tirées du recensement de 2016. Dans la mesure du possible, nous avons réalisé des tests du chi carré pour les variables nominales.

Résultats

En 2016 et 2017, 705 décès accidentels liés à une intoxication aiguë chez les aînés ont été documentés. Dans 61 % des cas, ce sont plusieurs substances qui ont contribué au décès. Le fentanyl, la cocaïne et l’éthanol (alcool) sont les substances les plus souvent en cause. Les maladies du coeur (33 %), la douleur chronique (27 %) et la dépression (26 %) ont souvent été documentées. Environ 84 % des aînés avaient pris contact avec des services de soins de santé au cours de l’année précédant leur décès. Le décès a eu lieu en présence d’un témoin dans 14 % des cas seulement.

Conclusion

Nos constatations permettent de mettre en lumière les facteurs sociodémographiques, contextuels et les antécédents médicaux pouvant avoir une incidence sur les décès liés à une intoxication aiguë due à une substance chez les aînés et d’ainsi proposer des aires clés de prévention.

How Oil Shocks Propagate: Evidence on the Monetary Policy Channel
Authors:   The University of Hong Kong, Miyamoto Wataru , Nguyen Thuy Lan ,   Federal Reserve Bank of San Francisco, Sergeyev Dmitriy ,   Bocconi University
Published: March 2024

Using high-frequency responses of oil futures prices to prominent oil market news, we estimate the effects of oil supply news shocks when systematic monetary policy is switched off by the zero lower bound (ZLB) and when it is not (normal periods) in Japan, the United Kingdom, and the United States. We find that negative oil supply news shocks are less contractionary (and even expansionary) at the ZLB compared to normal periods. Inflation expectations increase during both periods, while the short nominal interest rates remain constant at the ZLB, pointing to the importance of monetary policy for oil shock propagation.
Malvinas y las narrativas de derechos humanos
Authors: Fanelli Pablo Cristian
Published: March 2024

La Guerra de Malvinas —ocurrida entre el 2 de abril y el 14 de junio de 1982, producto de la decisión de la Junta Militar encabezada por el Tte. Gral. Leopoldo Galtieri— merece ser analizada dentro del contexto político de la última dictadura cívico-militar y las acciones del Gobierno de facto en su intento por legitimarse, perpetuarse y sostenerse en el poder político.
Resulta frecuente referirse al conflicto bélico desde la perspectiva de una gesta histórica nacional o como gesta heroica, al igual que suele referirse a quienes combatieron en las islas como héroes. Sin embargo, estas son representaciones de las que no participan todos los sectores sociales y que opacan la densidad de las narrativas de Malvinas y las disputas por el sentido sobre cómo y qué narrar de la guerra, y sobre las identidades de quienes han participado del conflicto.
Si bien es irrenunciable el reclamo por la soberanía nacional y la pertenencia legítima de las Islas Malvinas a nuestro territorio, es necesario analizar la guerra desde una perspectiva de derechos humanos, reconociendo sus particularidades y las disputas de sentido que existen en torno a las representaciones que los diferentes actores sociales formulan sobre Malvinas.
Lo scavo-scuola 2022
Authors: Adornato Gianfranco
Published: March 2024

La campagna di scavo 2022 si è concentrata sul  settore occidentale del santuario, al fine di definire meglio i limiti e le strutture del lato nord occidentale del tempio: la trincea di fondazione dei blocchi corre parallela al lato  settentrionale dell'edificio sacro, sebbene il posizionamento dei blocchi sia oggi leggermente  diverso. La struttura funge da muro di contenimento e terrazzamento. Nuovi dati archivistici  e grafici ci hanno spinto a rivolgere l'attenzione al tempio e alla definizione dello spazio  interno: sembra plausibile individuare una sorta di adyton nella parte occidentale della cella;  le scale e lo spazio sacro sono stati concepiti fin dalla prima fase dell'edificio. I materiali  archeologici provenienti dalla trincea presso l'altare hanno fornito dati significativi sulla  cronologia del santuario; inoltre, l'indagine nel settore nord-orientale dell'altare ha fornito  ulteriori informazioni sulla tecnica e sulla sequenza di lavorazione del monumento.
Vertebral heart size and vertebral left atrial size reference ranges in healthy Miniature Schnauzers
Authors: Murphy Lisa , Piscitelli Nicole , Solomon Jessica , Szlosek Donald , Nakamura Reid K
Published: March 2024

OBJECTIVE

The inclusion of vertebral heart score (VHS) and, more recently, the inclusion of the vertebral left atrial size (VLAS) in radiographic evaluation have become important screening tools for identifying dogs with occult cardiac disease. Several recent papers have shown there are interbreed variations in the VHS reference range. Our hypothesis is that the Miniature Schnauzer would also have a higher reference range for its VHS.

ANIMALS

The electronic medical records of IDEXX Telemedicine Consultants were searched for Miniature Schnauzers undergoing thoracic radiographs between March 1, 2022, and February 28, 2023.

METHODS

Dogs were included if they had 3 view thoracic radiographs performed and no evidence of cardiopulmonary disease was detected. Dogs with incomplete radiographic studies or cardiac or extracardiac disease were excluded. The VHS and VLAS measurements were performed by 2 board-certified cardiologists independent of one another.

RESULTS

A total of 1,000 radiographs were obtained of which 272 were included for the study. The overall range for the VHS in this cohort was 9.68 to 12.07 with a median of 10.9. For VLAS measurements, a range of 1.71 to 2.4 was documented with a median of 2.0.

CLINICAL RELEVANCE

The VHS for Miniature Schnauzers without cardiac disease was confirmed to be higher than the canine reference range.
Novel presentation of a feline patient with visceral and cervical lymph node hemangiosarcoma
Authors: Goddard Alexandra , Walters Kristine , Campbell Katy
Published: March 2024

OBJECTIVE

To report a novel presentation of feline hemangiosarcoma.

ANIMALS

A 14-year-old spayed female feline patient diagnosed with hemangiosarcoma of the spleen and a cervical lymph node.

CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES

The patient presented to the emergency service following a 1-week history of lethargy and hiding. Abdominal ultrasound revealed splenomegaly with multiple nodules and peritoneal fluid that was consistent with hemorrhagic effusion.

TREATMENT AND OUTCOME

The patient underwent a routine splenectomy and was started on doxorubicin. Histopathologic evaluation of the spleen confirmed visceral hemangiosarcoma. When the disease showed signs of progression, combination chemotherapy with cyclophosphamide and vincristine was initiated. Four months following presentation, a submandibular lymph node was removed and found to have metastatic hemangiosarcoma. From presentation to euthanasia, the patient survived 205 days.

CLINICAL RELEVANCE

Hemangiosarcoma is a rare cancer in feline patients, with a lack of veterinary literature on its presentation and chemotherapy protocols. The subject of this case report had a novel presentation of hemangiosarcoma and responded favorably to a chemotherapy protocol not previously described for this disease.
Study on transformations in land use in the functional context of extensive city ventilation routes using the example of Bródnowski Ventilation Corridor in Warsaw, Poland
Authors: Podawca Konrad , Pawłat-Zawrzykraj Agata , Karsznia Krzysztof
Published: March 2024

Ventilation corridors are critical for regulating the appropriate flow of urban air streams. Details on how they function, especially in a specific location, can be found in local eco-physiographic studies. Such analyses are designed during conceptual work on the conditions and directions of the development of a studied area. Such documentation includes advanced research on the impact of natural conditions on the area's growth and evolution. In Warsaw, Poland, such a study makes it possible to define various natural areas that are essential for the appropriate functioning of the city and increase its inhabitants’ well-being. This provides an initial basis for further analysis and motivates researchers to investigate the distribution of natural sites. It inspired the authors to assess the land-use structure in the context of the location of ventilation corridors. Thus, land use and land cover (LULC) modifications were examined in the context of their tendency to aid in the ventilation of the city. The object of the study is the Bródnowski Ventilation Corridor (BVC) – one of several designated for Warsaw in the spatial planning concepts of the 1980s and 1990s. In the research encompassing the years 1982–2020, the authors analysed the land use and roughness determined by the development characteristics and vegetation cover. References were made to current and archival planning documents, aerial photographs, satellite images, and the Topographic Objects Database BDOT10k. The research was prompted by the municipality's intention to urbanize the study area, which will undoubtedly eliminate the ventilation function of the southern part of the corridor and significantly reduce its remaining territory. Analysis of changes in the land cover of the south part of the corridor confirms its marginal importance for the city's ventilation. In this area, ongoing modifications proceed slowly, and urbanization – mainly low-rise and less intensive buildings – is limited. This zone has largely retained and is likely to maintain its favourable features from the point of view of ventilation and air regeneration.
Environmental and Human Impact on Gully Erosion Recorded in Fan Sediments: A Case Study of the Vilnius area, Lithuania
Authors: Smolska Ewa , Szwarczewski Piotr , Česnulevičius Algimantas , Mažeika Jonas
Published: March 2024

Geomorphological and sedimentological research carried out in the vicinity of Vilnius (SW Lithuania) aimed to determine the age and stages of development of gullies in relation to climatic conditions and human activity. Two gullies located on the northern slope of the Vilnia river valley were examined in detail. The sedimentological features of the sediments which form fans at the mouths of the gullies were analysed. Three main lithological units were distinguished. On the basis of radiocarbon datings, the beginning of gully erosion was determined to be in the Middle Ages. This process began with intensive settlement in this area. Further stages of a cutting which were distinguished include early modern times and the period from the seventeenth century to the present day.
Grief and Hope in Transition: An orienteering guide
Authors: Jönsson Li , Lindström Kristina , Lindkvist Christina , Larsen Jonas
Published: March 2024

In the project Grief and Hope in Transition, our approach to transition has been one of reorientation, a departure from the belief in new technologies as the solution to all kinds of problems, an attempt at deviation from modernity’s familiar territories and road maps. Together with people living in different rural areas in Sweden’s southern most landscape Scania, we formed a study group in future orienteering. This book is an outcome of the collaborative work done to explore how to transition into becoming fossil-free and how to let go of optimism that places agency elsewhere (such as in others' roadmaps and tech-fixes). It describes how we through designerly ways have addressed the challenge of how to restore a sense of attachments and commitment to the unfolding of the future.

On the thermodynamic stability of polycations
Authors: Tikhonov Denis S. , Lee Jason W.L. , Schnell Melanie
Published: March 2024

We present a simple approximation to estimate the largest charge that a given molecule can hold until fragmentation into smaller charged species becomes more energetically favorable. This approximation solely relies on the ionization potentials, electron affinities of the parent and fragment species, and also on the neutral parent's dissociation energy. By parametrizing these quantities, it is possible to obtain analytical phase diagrams of polycationic stability. We demonstrate the applicability of this approach by discussing maximal charge dependence on the size of the molecular system. A numerical demonstration for linear polyenes, monocyclic annulenes, and helium clusters is provided.

The Biomolecular Corona (BC) is a typical phenomenon that occurs at the interface between the nanomaterial and the surrounding media, involving the adsorption or the desorption of macromolecules at this interface. Studying BC dynamic properties on soft nanomaterials (i.e., liposomes or extracellular vesicles) proves to be challenging. Advancing in situ methodologies for investigating BC on soft nanoparticles is essential for elucidating the intricate interplay between surface composition, properties, and dynamic BC formation. In this study, we present new evidence of distinct dynamics in BC formation for two extracellular vesicle (EV) subtypes. Utilizing Fluorescence Correlation Spectroscopy (FCS) coupled with a fluorescent monoclonal antibody as a corona probe enabled the characterization of macromolecule exchange at the EV surface and the dynamic evolution of the BC.
Data Science Enables Chemical Interpretation of HBC-Catalyzed Polymerization for Poly(disulfide)s

Published: March 2024

H-Bonding catalysts (HBCs) has gained widespread success in improving the selectivity of organic synthesis. The complexity of potentially engaging noncovalent interactions have imposed significant challenges in deciphering the contributing factors of these catalytic reactions. Herein, we present the use of interpretable machine learning on HBCs applied in poly(disulfide) synthesis, wherein the epiquinine-derived thiourea HBCs enable simultaneous regioselectivity control and rate acceleration over the otherwise unselective and already rapid polymerization. A training set of 28 catalysts with variation on the phenyl substituents were synthesized and tested to gather experimental observables: the apparent rate (kp) and regioselectivity (Pss). Considering the limited data size, we applied the feature-sensitive XGBoost algorithm for supervised machine learning. Upon screening over 64 potentially relevant descriptors, a reasonable fitting of the observables was established for kp (R2 = 0.76) and Pss (R2 = 0.91), and the key catalyst features necessary for achieving high reaction rates and regioselectivity were deconvoluted. The model suggests that sterically hindered, heavy atom-containing substituents or strongly electro-withdrawing groups on the HBC adversely affect the reaction rate. Substituents enhancing the electrostatic potential of the aromatic N atom are beneficial for achieving high regioregularity, while presence of ortho-substituents on the phenyl ring is unfavorable.
Fine-Tuning Property Domain Weighting Factors and the Objective Function in Force Field Parameter Optimization
Authors: Strickstrock Robin , Hagg Alexander , Hülsmann Marco , Kirschner Karl , Reith Dirk
Published: March 2024

Force field (FF) based molecular modeling is an often used method to investigate and study structural and dynamic properties of (bio-)chemical substances and systems. When such a system is modeled or refined, the force field parameters need to be adjusted. This force field parameter optimization can be a tedious task and is always a trade-off in terms of errors regarding the targeted properties. To better control the balance of various properties’ errors, in this study we introduce weighting factors for the optimization objectives. Different weighting strategies are compared to fine-tune the balance between bulk-phase density and relative conformational energies (RCE), using n-octane as a representative system. Additionally, a non-linear projection of the individual property-specific parts of the optimized loss function is deployed to further improve the balance between them. The results show that the overall error is reduced. One interesting outcome is a large variety in the resulting optimized force field parameters (FFParams) and corresponding errors, suggesting that the optimization landscape is multi-modal and very dependent on the weighting factor setup. We conclude that adjusting the weighting factors can be a very important feature to lower the overall error in the FF optimization procedure, giving researchers the possibility to fine-tune their FFs.

Numerous applications from diverse disciplines reduce to solving generalized equations in a Banach space setting. These equations are solved mostly iteratively, when a sequence is generated approximating a solution provided that certain conditions are valid on the starting point and the operators appearing on the method. In particular, Newton-like methods are developed whose specializations reduce to well known methods such as Newton, modified Newton, Secant, Kurchatov and Steffensen to mention a few. A unified semi-local analysis of these methods is presented using the contraction mapping principle under the Aubin property of a set valued operator, and generalized continuity assumption on the operators on these methods.

La delincuencia en México y la cohesión social. Un modelo econométrico de predicción
Authors: Guerrero Escamilla Juan Bacilio
Published: March 2024

Uno de los daños más importantes y de gran impacto al deterioro de la sociedad, es el delito. Todas las sociedades lo tienen y son parte de su vida, de sus relaciones cotidianas, de sus instituciones, de su reglamentación y le dedican parte de sus recursos. Todas las sociedades mantienen una gran preocupación sobre el  comportamiento de este fenómeno; lo analizan y lo estudian tratando de comprender cuáles son sus formas, tamaños, estadísticas, causas y funcionamiento, pero sobre todo sus límites. Esta preocupación tiene sentido en tanto los límites definen las fronteras de la descomposición social, del deterioro del tejido social, de la decadencia de sus instituciones, de las prácticas de hacer efectivo el sistema de procuración de justicia, del sistema de leyes y la regulación de las formas de convivencia de los Estados modernos.

Authors: Özmen Gül Bayramiye , Şahiner Eren
Published: March 2024

In our study, it was observed that the EPR signals of table sugar irradiated with gamma rays at 3 kGy, 5 kGy, 10 kGy increased in proportion to the increasing dose. The fading in the signals was investigated by taking into account the peak-to-peak heights (Ipp) in the EPR spectra of table sugar. The stability of radicals was monitored by performing EPR measurements on sugar samples irradiated with high doses of gamma rays (Co-60) on 29.06.2020, 23.03.2021, 28.06.2021, 05.08.2021. Suitability evaluation was made with Z score, which is a statistical test to determine fading. It was observed that there was almost no loss in the EPR signals of sugar for 14 months.

Also table sugar; Similarities have been shown by comparing the EPR spectra of the fruits used in the TS EN 13708 Foodstuffs - Standard for determining whether foodstuffs containing crystal sugars are irradiated by ESR spectroscopy. Thanks to these similarities, it has been suggested that fruits can also be used as dosimeters, depending on the sugar they contain.

Bu çalışmada; her ikisinin de kendi yapılarını koruyarak sıvı haldeki iki farklı malzemeden metal-metal kompozit üretiminin yapılabilirliği araştırılmıştır. Çalışmada her ikisi de sıvı halde olan Küresel Grafitli Dökme Demir (KGDD) ve Lamel Grafitli Dökme Demir (LGDD) kullanılarak kum kalıba döküm yöntemiyle üretimler yapılmıştır. Çalışmada 9 farklı parametrede döküm numuneleri üretilmiş, metal mikroskobu ile mikro yapısal ve çekme deneyleri ile mekanik özellikler açısında değerlendirilerek kendi aralarında kıyaslanmıştır. İyi bir sıvı-sıvı karışımında malzeme kalitesinin ve döküm parametrelerinin büyük bir rol oynadığı, bu durumun doğrudan ortaya çıkan kompozitin yapısal ve mekanik özelliklerini etkilediği gözlenmiştir. LGDD’ in KGDD’ e yapısal etkisi net bir şekilde gözlenmiş olup mikro yapılarda küresel grafit formunum bozulmasına neden olduğu görülmüştür. Ayrıca sıcaklık etkisi düşünülerek uzak bağlantılı yolluk tasarımları ile döküm sıcaklık değerlerinin değiştirilerek kompozitin mikro yapısal ve mekanik özelliklere etkileri incelenmiş ve sonuçlar ara form olan VGDD (Vermiküler Grafitli Dökme Demir) malzeme ile kıyaslanmıştır. Ayrıca sonuçlar, kullanılan malzemelerin birbirlerine ilgileri veya etkilerinin yüksek olması neticesinde sonuçların beklendiğinden daha düşük olabileceğini de göstermiştir.

Published: March 2024

Silica-based ceramic cores are significantly used in the investment casting process. For this purpose, they must exhibit sufficient flexural strength and thermal resistance. In this study, the effect of zircon-alumina fibers on the
mechanical and chemical properties of the ceramic cores was evaluated. Samples were produced by injection molding under 12 kPa pressure and at 115 °C temperature. The impact of incorporating varying quantities (0, 1 and 2Wt %)
of alumina-zircon fibers on the silica-based cores’ mechanical and chemical characteristics was examined. MOR, XRD, SEM and leachability characterization analysis were performed. The results reveals effective enhancement for mechanical
and chemical properties. The Rheological Characterization demonstrate that the addition of fibers at 2 wt% effectively increased the viscosity and yield stress of the paste. Furthermore, The MOR results show that the flexural strength
of cores increases up to 43% and the leachability enhances up to 44%.
