Published: July 2024

Indeed, nanofluids have garnered significant interest in various fields due to their numerous advantages and potential ap-plications. The appeal of SiO2 nanofluid, in particular, lies in its low preparation cost, simple production process, controlled chemistry, environmental safety and its exceptional ability to be homogeneously suspended in the base fluid, which makes it a promising candidate for a variety of applications. In this study, we investigate the flow analysis of a water based silicon dioxide nanofluid, passing over a stretched cylinder while subjected to a continuous magnetic field, including Joule heating effects. The research involves the development of a mathematical model and the formulation of governing equations rep-resented as partial differential equations. These equations are subsequently transformed into non-linear ordinary differential equations through suitable transformations. To obtain a numerical solution, the MATLAB bvp4c solver technique is em-ployed. The study investigates the implications of dimensionless parameters on velocity and thermal distributions. It is observed that the velocity distribution f'(η) exhibits a direct relationship with the volumetric fraction ϕ and an inverse relationship with the unsteadiness parameter S, the magnetic parameter M, and the temperature distribution θ(η) shows an enhancement for the increasing ϕ and M, as well as the Eckert number. However, it declines against S and the Prandtl number. The results for local Nusselt number and skin frictions are depicted in Tables.

Authors: Zach Sima , Lidor Ronnie
Published: July 2024

The purpose of the current study was to examine the challenges of distance learning (DL) teacher education (TE) experienced by decision makers, lecturers, and pedagogical instructors at PE teacher training colleges during the COVID-19 pandemic, and explore how these challenges were dealt with. In-depth interviews were conducted with 24 participants from five colleges of education in Israel where physical education teacher training is taught. A trifold process characterizes the investigated institutions: Frustration and a sense of helplessness, high self-satisfaction regarding the online instruction, and frustration combined with hope that the era of distance teaching will soon end. Most decisions regarding the changes and transitions were made by the teaching staff. Our findings can help those involved in teacher education in understanding how organizational and pedagogical decisions were made under conditions of uncertainty and crisis, and how these training programs were adapted to the new circumstances. Our findings may also serve as a basis for future discussion on long-distance teacher education.

Published: July 2024

A facile sol-gel procedure was employed to create refractive-index gradient SiO2 antireflective (AR) films. A monolayer film, characterized by the porous crosslinking framework, was fabricated with a designed volume ratio mixture both with colloidal silica suspension and soluble organic polysiloxane. The upper layer for the bilayer film was a hexamethylisilazane (HMDS) modified colloidal silica suspension, leading to the film surface transfer to hydrophobic. The strategic design of nanostructures in the bottom and upper layers resulted in a refractive-index gradient SiO2 film with enhanced AR properties. The bilayer film demonstrated a transmittance of 99.5% at 1064 nm, accompanied by a notable reduction in reflectivity. Moreover, the laser-induced damage threshold of the bilayer film was increased by 30%, rising to as high as 24.7 J/cm2. The SiO2 nanostructured film both showed a refractive-index gradient structure with excellent AR properties and exhibited good laser damage resistance.

Authors: Milano Deo Cerlova , Muhammad, SpOG(K)-Onkogin Dr. dr. Syamel
Published: July 2024

Background : Invasive mole (IM) is a frequent complication of gestational tropoblastic neoplasia (GTN). These tissues invade the myometrium deeply, occasionally affecting the peritoneum or vaginal vault. The prevalence of an invasive mole causing uterine rupture is uncommon.Â  Case Report : We discuss the case of a 46-year-old nulliparous woman who presented to the emergency room complained severe abdominal pain that had been present for 4 hours. Patient had a history of complete mole evacuation 2 months ago with persistently elevated beta-human chorionic gonadotropin (B-HCG). .Â  The patient was diagnosed with suspected uterine rupture due to an invasive moleÂ Â  and advised to undergo hysterectomy. Total abdominal hysterectomy was performed with the preservation of both ovaries. Choriocarcinoma was diagnosed histopathologically, and the patient was prepared for chemotherapy using EMA-CO protocols. Conclusion :Â  Perforation of the uterus by an invasive mole is a rare but lethal complication. Although hysterectomy followed by chemotherapy is the standard treatment for this condition, several studies demonstrate the benefit of conservative management in terms of fertility preservation in reproductive-aged women.

Published: July 2024

Introduction: In Peripartum Cardiomyopathy (PPCM), heart function will generally return to normal a fewmonths after delivery, but in some cases poor outcomes might occur, therefore early detection and managementare crucial. This case series study aims to get an overview of PPCM cases in a type-B referral hospital in Gianyar,Bali.Case Presentation: This study presents 3 cases of PPCM that showed symptom onset in the antepartum period(the third trimester of pregnancy). Two out of three cases were nulliparous with maternal age <30 years, andwent through a Cesarean Section. All three cases underwent treatment in the Intensive Care Unit and showedimprovement in their condition.Discussion: Until now, the heterogeneity of PPCM diagnostic criteria has become an obstacle to its treatment,thus the reported incidence tends to be low. This is likely due to the diagnosis of PPCM which is an exclusiondiagnosis from other causes of heart failure. Echocardiography and NT-ProBNP examinations should be done,which, although not specific, may lead to a diagnosis of PPCM when combined with a thorough patient history.The availability of supporting examination modalities in many regions in Indonesia are varied thus referrals areusually needed, resulting in the delay of PPCM cases management.Conclusion: All pregnant women who experience dyspnea during the third trimester of pregnancy, along with afamily history of heart disease, need to undergo close examination and supervision due to the suspicion of PPCM.Early detection and treatment are the main key to successful management of PPCM cases

The purpose of the article is to analyze the emergence and stages of development of the phenomenon of "cancellation culture". The subject is the formation of a concept, and the object is the modification of the "culture of cancellation" in the context of socio-cultural and political events. The novelty of the work lies in the substantiation of the concept of "culture of cancellation" from the perspective of Russian discourse. The authors study the "abolition" of an entire country and its culture on the example of Russia, as a result of which the ways of ousting the country from international discourse and the consequences of this act were revealed. The concept of "cancellation culture" is firmly fixed in the language resource of modern journalists and media analysts, this vocabulary unit activates a significant interest in in-depth research in domestic and foreign discourse. The "culture of abolition" as a phenomenon arose in the public environment of the United States and Europe at the turn of the twentieth and twenty-first centuries as an instrument of social justice, which is presented as a modern form of ostracism that allows manipulating public opinion. Conceptual analysis, sociolinguistic analysis and intent analysis were used as methods and approaches in the research. The concept of "culture of cancellation" can be considered as a tool for manipulating society, in this case, the process of deformation by the conceptual sphere of the ethnocultural dominant of the subject or society as a whole is analyzed. Similar phenomena are observed in the examples of ethnocultural groups, when certain events occur in the surrounding reality that affect the consciousness of the subject. Negative facts have an impact on a person, erasing established principles and values from consciousness, in the structure of social relations. Scientists have revealed that, under these circumstances, the concept, as an instrument of influence, is transmitted using information received by a certain ethnocultural group. In the study, we also established that a concept is an algorithm for understanding certain cultures, for example, psychological, historical, cultural, logical–semantic, linguistic, etc. In this regard, the "culture of cancellation" as a concept is a process in which certain ideas arise, which are formed against the background of events in the information and social environment and society. The process of "cancellation culture" is rapidly spreading not only within a single country to achieve certain goals, but also throughout the modern world.

Pierwotne doświadczenie pentekostalne i jego aspekty według Dz 2,1–4,38 w kontekście religijnego doświadczenia
Authors: Tomczyk Dominik
Published: July 2024

Korzeni współczesnego pentekostalizmu należy szukać w tekstach Nowego Testamentu, szczególnie w Dziejach Apostolskich. Opisują one, w jaki sposób Duch Święty działał w pierwotnym Kościele i jak był doświadczany przez pierwszych chrześcijan.Autor analizuje zagadnienie pierwotnego doświadczenia pentekostalnego w świetle tekstu Dz 2,1–4,38. Omawia istotę doświadczenia religijnego jako doświadczenia Ducha. Pentekostalne doświadczenie jest doświadczeniem zarówno indywidualnym, ale i wspólnotowym. Nie posiada ono charakteru skończonego, jednorazowego, ale jest doświadczeniem powtarzalnym. Ponadto istotę pentekostalnego doświadczenia Boga stanowi jego aspekt misyjny. Doświadczenie Ducha Świętego otwiera nowy rodzaj relacji człowiek – Bóg, ale także człowiek – drugi człowiek.
Photophysical properties of donor(D)-acceptor(A)-donor(D) diketopyrrolopyrrole (A) systems as donors for applications to organic electronic devices
Authors: Rosa Nathalia , Borges Jr Itamar
Published: July 2024

Fourteen substituted diketopyrrolopyrrole (DPP) molecules in a donor (D)-acceptor (DPP)-donor (D) arrangement were designed. We employed density functional theory (DFT), time-dependent DFT and the ab initio wave function second-order algebraic diagrammatic construction (ADC(2)) methods to investigate theoretically these systems. The examined aromatic substituents have one, two or three hetero- and non-hetero rings. We comprehensively investigated their optical, electronic and charge transport properties to evaluate potential applications in organic electronic devices. We found that the substituents based on one, two or three aromatic rings bonded to the DPP core functioning as a donor can improve the efficiency of an organic solar cell by fine-tuning the HOMO/LUMO levels to match acceptors in typical bulk heterojunctions acceptors. Several properties of interest for organic photovoltaic devices were computed. We show that the investigated molecules are promising for applications as donor materials when combined with typical acceptors in bulk heterojunctions because they have appreciable energy conversion efficiencies resulting from their low ionization potentials and high electronic affinities. This scenario allows a more effective charge separation and reduces the recombination rates. A comprehensive charge transfer analysis shows that D – A (DDP) – D systems have significant intramolecular charge transfer, further confirming their promise as candidates for donor materials in solar cells. The significant photophysical properties of DPP derivatives, including the high fluorescence emission, also allow these materials to be used in organic light-emitting diodes (OLEDs).

Porous materials have attracted considerable interest as water sorbents due to their potential in a broad range of water sorption-related applications. Metal-organic frameworks (MOFs) are particularly notable for their high porosity and tunability. However, their limited hydrolytic stability often results in pore collapse, which significantly hinders their water sorption performance. To address this issue, an innovative design strategy based on reticular chemistry is essential to enhance structural stability and ensuring efficient water sorption. Herein, we introduce a novel synthetic approach for constructing a merged-net MOF structure using metallolinkers. Specifically, we employed a porphyrin linker to successfully synthesize a porphyrin-based merged-net MOF, UPF-5. This MOF demonstrates significantly enhanced hydrolytic stability and improved water sorption performance while maintaining high pore volume. Additionally, the structure of UPF-5 allows for the modification of accessible Zr6 nodes, enabling control over the pore environments and fine-tuning the water sorption properties. This programmable synthetic strategy for porphyrin-based merged-net MOFs not only significantly enhances the structural stability for practical applications, including water sorption, but also advances reticular chemistry by discovering unprecedented topologies in MOF chemistry.

Measured and calculated time-resolved photoelectron spectra and excited-state molecular dynamics simulations of photoexcited gas phase Fe(CO)5 and Cr(CO)6 are presented. Samples were excited with 266 nm pump pulses and probed with 23 eV photons from a femtosecond high- order harmonic generation source. Photoelectron intensities are seen to blue-shift as a function of time from binding energies characteristic of bound electronic excited states via dissociated-state energies towards the energies of the dissociated species for both Fe(CO)5 and Cr(CO)6 but differences are apparent. The excited-state and dissociation dynamics are found to be faster in Cr(CO)6 because repopulation from bound excited to dissociative excited states is faster. This may be due to a stronger coupling between bound and dissociative states in Cr(CO)6, a notion supported by the observation that the manifolds of bound and dissociative states overlap in a narrow energy range in this system.
Ultrathin surface-attached hydrogel coating for potential reversible nanogluing of implants

Published: July 2024

A multifunctional copolymer of N-(2-Hydroxypropyl)methacrylamide (HPMA) and a phosphonate-containing monomer was developed with the aim of applying a hydrogel coating to implant surfaces. For this purpose, a copolymer was prepared that could bind to the implant surface (e.g. titanium) via a phosphonate group. A photocrosslinkable group (phenyl azide) and hydrophilic groups were also incorporated to form a hydrogel. Coatings of these polymers produced by spin coating and subsequent photocrosslinking were characterised by laser ellipsometry, which gave controlled dry layer thicknesses in the range 40 to 140 nm. Furthermore, the swelling ability was investigated by in-situ ellipsometry in different aqueous media. According to these measurements, the coatings can swell up to three times the initial dry film thickness, depending on their crosslinker content. We also validate long-term stability under physiological conditions. In addition, the hydrogel coatings can immobilise different types of silica nanoparticles (non-porous silica (15 nm), nanoporous silica (40 nm) and periodic mesoporous organosilica (100 nm), which makes them suitable for nanogluing. Preliminary tests have shown that a PDMA hydrogel can indeed adhere to the surface-bound hydrogels by way of nanoparticles.

Structure directing agents (SDAs) are widely used in the synthesis of ubiquitous porous materials, such as zeolites, but their application and role in the synthesis of metal-organic frameworks (MOFs) has been comparatively understudied. Here we report a diverse family of anionic MOFs with all frameworks constructed exclusively from the same metal cation and plant-based organic linker—Zr(IV) cations and ellagate anions. Applying the same synthesis conditions but only changing the species of the SDA resulted in 10 novel zirconium ellagate MOFs (denoted SU-103 – SU-112) with varying dimensionality, topologies, Zr(IV) coordination geometries, intermolecular framework interactions, and framework interpenetration. Modern electron diffraction and electron microscopy techniques revealed the location of the SDA molecules in the pores of all MOFs, enabling a detailed study of their interactions. Despite having similar framework compositions, the properties of these MOFs noticeably differ due to the different ammonium SDAs and the unique framework structures obtained. The MOFs demonstrate chemical stability in aqueous media, basic conditions, and concentrated salt solutions, which is attributed to the strong Zr-catecholate chelating interactions consolidating the frameworks. We anticipate these 10 MOFs are only a small portion of a potential plethora of MOFs that could be discovered within this system. This lays the groundwork for the discovery of many other chemically robust structure-directed MOFs made with different cationic SDAs, framework metal cations, as well as other organic linkers with polyanionic functional groups.
