Optically stimulated luminescence properties of chicken eggshell derived hydroxyapatite for dosimetry applications
Authors: Panda Madhusmita , Joshi Shailesh , Annalakshmi O. , Venkatraman B. 
Published: October 2024

Abstract
This study investigated the optically stimulated luminescence (OSL) characteristics of hydroxyapatite (HAp) derived from chicken eggshells, a readily available bio-waste, for low-level radiation dosimetry applications which is less explored. The eggshells were employed as a calcium source in HAp synthesis. The X-ray diffraction and Fourier transform infrared spectroscopy results confirmed its purity and crystallinity. The OSL properties of the synthesized HAp demonstrated excellent reproducibility, reusability, and dose linearity up to 20 Gy, with a measurable dose range of 22 mGy. The favorable OSL characteristics, combined with the utilization of waste materials, offer significant advantages for environmental and medical radiation monitoring.
Unusual relaxation phenomena in the 57Fe Mössbauer spectra of FeX3 (X = Cl, NO3, ClO4, MnO4, 1/2(S2O8)) complex salts containing urea, methylated urea, chlorido or aquo ligands: studies on the influence of the ligand sphere and deuteration

Abstract
Mössbauer spectra of FeIII complex salts with urea-related ligands show a broadened line due to magnetic relaxation. The origin of the relaxation is not known, mostly spin–spin type is considered. A study of a large number of compounds can be helpful to show differences in the Mössbauer parameters and to see the infuence of the chemical environment on the relaxation. We have evaluated the Mössbauer spectra of 13 compounds recorded at various temperatures with the Blume–Tjon two-state relaxation model and with the (unrestricted) Afanasev–Gorobchenko model. The latter showed significant differences between some salts, and proved the presence of spin–lattice relaxation.

Portrait of the Artist as a Non-Artist. Matryoshka Roles and the Heteronomization of the Italian Art Field
Authors: Sabetta Lorenzo 
Published: October 2024

AbstractThis paper examines how Italian visual artists are now structurally encouraged to be proficient in performing activities unrelated to field-specific criteria, or – to use the words of one respondent – why they are supposed to “be good at being incredibly good at doing stuff they don’t know how to do.” Drawing on qualitative data (N = 135), four dimensions of unartistic yet binding concerns are explored: networking relationality, bureaucratic “callification,” systemic politics, and outward visibility. To analyze this dynamic, the concept of “Matryoshka roles” is introduced. Although uncharacteristic of artists’ work and nested inside its surface depiction (Matryoshka), each dimension entails a set of injunctions and sanctioned behavior (roles) that reconfigure the reality of contemporary visual artists and vitiate the separation between internal vs. external principles of hierarchization. Reflecting on the autonomy of the field of visual art as a transitory historical phase, mechanisms of fields’ heteronomization are addressed. By considering a series of factors (e.g., differences among early- and late-career artists, presence on social media, perception of heteronomous practices, most distinctive accomplishments, career junctions), the increasing pressure of meta-fields of economics, power, and state is detailed.
Development of microflow ultra high performance liquid chromatography-mass spectrometry metabolomic assays for analysis of mammalian biofluids
Authors: Harwood-Stamper Annie J. , Rowland Caroline A. , Dunn Warwick B. 
Published: October 2024

Abstract
Introduction and objectives
The application of untargeted metabolomics assays using ultra high performance liquid chromatography-mass spectrometry (UHPLC-MS) to study metabolism in biological systems including humans is rapidly increasing. In some of these studies there is a requirement to collect and analyse low sample volumes of biofluids (e.g. tear fluid) or low cell and tissue mass samples (e.g. tissue needle biopsies). The application of microflow, capillary or nano liquid chromatography (≤ 1.0 mm column internal diameter (i.d.)) theoretically should accomplish a higher assay sensitivity compared to analytical liquid chromatography (2.1–5.0 mm column internal diameter). To date, there has been limited research into microflow UHPLC-MS assays that can be applied to study samples of low volume or mass.

Methods
This paper presents three complementary UHPLC-MS assays (aqueous C18 reversed-phase, lipidomics C18 reversed-phase and Hydrophilic Interaction Liquid Chromatography (HILIC)) applying 1.0 mm internal diameter columns for untargeted metabolomics. Human plasma and urine samples were applied for the method development, with porcine plasma, urine and tear fluid used for method assessment. Data were collected and compared for columns of the same length, stationary phase and stationary phase particle size but with two different column internal diameters (2.1 mm and 1.0 mm).

Results and conclusions
All three assays showed an increase in peak areas and peak widths when applying the 1.0 mm i.d. assays. HILIC assays provide an advantage at lower sample dilutions whereas for reversed phase (RP) assays there was no benefit added. This can be seen in the validation study where a much higher number of compounds were detected in the HILIC assay. RP assays were still appropriate for small volume samples with hundreds of compounds being detected. In summary, the 1.0 mm i.d. column assays are applicable for small volume samples where dilution is required during sample preparation.

AbstractTurmeric, specifically its curcuminoids such as curcumin (C21H20O6), possesses extensive therapeutic benefits including anti-inflammatory, anticancer, and anti-aging properties. However, curcumin’s clinical effectiveness is significantly limited by its hydrophobic nature, leading to poor bioavailability. This study aims to enhance the solubility and bioavailability of curcumin through the development of liquisolid compact dispersion formulations. To address curcumin’s limited water solubility (3.12 mg/l at 25 °C) and high oil–water partition coefficient ($$\text{log}Kow=3.29$$

), we employed a central composite design (CCD) to optimize liquisolid compact dispersion formulations. The optimization focused on the tablet’s physical properties, such as hardness, disintegration time, and dissolution rate at 30 min. Critical formulation components included Tween 80 as the liquid vehicle and Aerosil 200 as the coating material, serving as independent variables in the optimization process. The optimized formulation, containing 30 mg of Tween 80 and 75 mg of Aerosil 200, significantly improved curcumin’s dissolution rate. Experimental results confirmed the formulation’s effectiveness, with a marked reduction in the time to dissolve 63.2% of the drug to 165 min, compared to 300 min for conventional formulations. Differential scanning calorimetry and Fourier-transform infrared spectra indicated a transformation of curcumin into a non-crystalline state and the formation of hydrogen bonds with Tween 80, contributing to enhanced solubility. This study successfully demonstrates a viable strategy to enhance the bioavailability of curcumin through liquisolid compact dispersion formulations. By addressing the solubility challenges of curcumin, this technique presents a significant advancement in improving the clinical applicability of BCS class II and IV drugs, potentially benefiting a wide range of therapeutic applications.

Delving into preschool teachers’ revenge – a mediated-moderated model that explores the deeper nuances of hot and cold revenge among preschool teachers
Authors: Itzkovich Yariv 
Published: October 2024

AbstractWhile revenge has captured the attention of researchers, certain nuances have been disregarded. Some studies have recognized the existence of two distinct forms of revenge — “hot” or “cold” — but the specific conditions underlying these variants have been overlooked. The present two studies delve into the boundary conditions that differentiate hot and cold revenge. By analyzing data collected from 172 and 107 preschool teachers in studies one and two, respectively, this research confirms the presence of both emotional (hot) and calculated (cold) revenge responses. Furthermore, it uncovers the mechanisms driving these two revenge types and identifies a trade-off between vertical solidarity motivated by pragmatic ambitions and revenge, representing divergent resource acquisition strategies. The findings' relevance for decreasing vindictive behaviours and future research avenues are discussed.

Published: October 2024

AbstractBlockchain technology is known for its transparency properties due to its publicly available, immutable data. Yet, as data availability does not inherently ensure transparency, further analytical methods may be required for human interpretation of data traces. Process mining has emerged as a popular toolbox for understanding processes and how they are executed in practice. The paper studies process mining as a method to enhance the transparency of blockchain data. To this end, two popular Ethereum applications were analyzed using process mining: the prediction and betting marketplace Augur and the network marketing platform Forsage. Observations from the process-mining analyses are used to discuss if process mining can serve as a method to establish transparency of a blockchain. For both applications, new insights are generated for usage scenarios such as application redesign, security analysis, user behavior analysis, and revealing blind spots in Augur’s and Forsage’s documentation. The paper concludes that there is evidence that process mining can serve as a method to enhance transparency in blockchains at the cost of technical setup and knowledge acquisition.

Published: October 2024

AbstractThis qualitative study delves into the facilitators and barriers surrounding cervical cancer prevention among Latina women in Georgia, with a specific focus on the impact of community-based organizations (CBOs). Employing semi-structured interviews with healthcare providers and representatives from CBOs, faith-based organizations, and other key stakeholders, the study uncovers key themes and subthemes shaping cervical cancer disparities. Themes such as challenges in cross-cultural healthcare access, difficulties due to lack of US citizenship, and limited mobility emerge as significant barriers, while community and family support stand out as crucial facilitators to cancer prevention. Additionally, the study examines community intervention methods from CBOs to target cervical cancer disparity, highlighting the importance of public awareness campaigns, building trust within the Latina community, and providing medical support tailored to immigrant populations. Through this comprehensive examination, the study not only offers invaluable insights into the intricate web of issues surrounding cervical cancer prevention but also endeavors to serve as a catalyst for targeted interventions and evidence-based policies aimed at ameliorating cervical cancer disparities among immigrant Latinas in Georgia and beyond.

Clays as Micro-Electrodes in Environmental Detoxification
Authors: Pamukcu Sibel 
Published: October 2024

AbstractIn-situ reduction of contamination in soil and groundwater is an ongoing challenge that often requires a multi-pronged approach for effective and efficient clean-up. Spontaneous or assisted electrochemical reactions that break down certain pollutants held on clay surfaces can render natural clays a unique and powerful ally in environmental mitigation of contaminated soils. Application of a low-level DC electric field (mV/cm) has been shown to facilitate transformation of some compounds and ionic species through redox reactions in addition to transporting them through the pores in wet clay soils. Results from previous tests suggest that the natural electrochemical processes that promote pollutant sloughing or chemical breakdown can be enhanced for targeted treatment by applying low-level electric field to the contaminated soil with clay content. The central idea of this hypothesis is that clay, due to its surface charge and electrostatic interaction with adjacent pore fluid, acts as a “micro-electrode” through the diffused double layer (DDL) interactions when subjected to an external electric field. This hypothesis, proven viable, may unlock potential ability of natural clays to generate beneficial reactions for detoxification of contaminated sub-surfaces. Evidence from past laboratory experiments accompanied by a proposed electrical model of clay behaving as a micro-electrode are presented in this paper. The laboratory experiment results support the proposed electrical model.

Abstract
Introduction
This study is a prospective, randomized, subject/evaluator-masked clinical trial in a single-center clinical setting. The purpose of the study is to compare the clinical performance of Tecnis Symfony Optiblue IOL (models ZXR00V and ZXW150) with violet light filter (VLF) and manufacturing improvements versus Tecnis Symfony IOL (models ZXR00 and ZXT150) with ultraviolet light filter (UVF) in patients undergoing cataract surgery.

Methods
Patients with cataracts aged ≥ 22 years were randomly assigned 1:1 to bilateral implantation with ZXR00V/ZXW150 (VLF group) or ZXR00/ZXT150 (UVF group). Key endpoints at 6 months postoperative included patient reported nighttime dysphotopsia symptoms, 25% low contrast visual acuity with glare, and patient satisfaction.

Results
Sixty patients were implanted with ZXR00V/ZXW150 (30) or ZXR00/ZXT150 (30). At 6 months, the VLF group did not show a statistically significant differences in mean monocular photopic uncorrected distance visual acuity (UCDVA), best-corrected distance visual acuity (BCDVA), uncorrected near visual acuity (UCNVA) (40 cm), or distance-corrected near visual acuity (DCNVA) (40 cm) compared to the UVF group. At 1 month, patients in the VLF group reported significantly less difficulty due to halo (p = 0.016) and starburst (p = 0.028) symptoms. By the 6 months, dysphotopsia complaints were no longer significantly different between the groups. Although the VLF group trended toward better low contrast visual acuity and patient satisfaction, statistical significance was not reached.

Conclusions
Managing the patients’ expectations is key to achieving success. At the 1-month visit the patients who reported dysphotopsia complaints in the VLF group had significantly less difficulty with starbursts and halos as compared to the UVF group. By the 6-month visit, there was no significant difference between the two groups in the difficulty with starbursts and halos.

Nello specifico, si presenta un aggiornamento su: femminilizzazione facciale, condrolaringoplastica e chirurgica vocale, mastoplastica additiva, clitorolabioplastica e orchiectomia.
Five key actions for redesigning adult skills assessments from learners, employees, and educators
Authors: Suárez-Álvarez Javier , Oliveri María Elena , Zenisky April , Sireci Stephen G. 
Published: October 2024

AbstractSummative assessments provide data to evaluate the effectiveness of schools, teachers, and educational policies, contributing to a robust accountability system worldwide. However, educators and scholars argue that summative assessments do not effectively promote ongoing learning, enhance teaching practices, or align with the skills required in the workplace. Furthermore, traditional summative testing approaches lack culturally responsive practices and overlook the diverse needs of adult learners. This article summarizes research conducted through focus groups, interviews, and listening sessions to gain insight into learners’, employees’, and educators’ perceptions of assessment needs in adult education and workforce development in the United States. We conducted six focus groups, four interviews with diverse learners and employees, and two listening sessions with educators and administrators. In-person and online formats were used in Spanish and English. The results indicate that the backgrounds and needs of learners, employees, and educators in this study are diverse, but all agree there is a strong need for open assessment resources for mid- and lower-skilled and culturally diverse learners that provide them with useful information to help them achieve their personal and occupational goals. Educators in this study needed assessment information connected to the standards and curriculum that guide their instruction, and employees and their employers needed tools to identify and train adult learners for in-demand skills within industries and occupations. Assessing adult skills requires addressing these needs by designing tests that focus on learners’ characteristics and goals and are integrated with educators’ and employers’ needs and goals. The research findings suggest that assessments should be personalized to learners, integrated with instruction or job training, and embrace the cultural diversity of the adult learner population better to serve learners, employees, and educators.

AbstractIn view of wide-ranging application to the biomedical field, this work investigates the mechanical and electrical properties of a composite made of Single Wall Carbon Nanotubes (SWCNT) bundles self-grafted onto a poly-dimethyl-siloxane (PDMS) elastomer, particularly Sylgard 184, that has well assessed biocompatible properties and is commonly used in prosthetics. Due to the potential risks associated with the use of carbon nanostructures in implanted devices, we also assess the viability of cells directly grown on such composite substrates. Furthermore, as the stability of conductive, stretchable devices made of such composite is also crucial to their use in the medical field, we investigate, by different experimental techniques, the grafting of SWCNT bundles deep into PDMS films. Our findings prove that penetration of SWCNT bundles into the polymer bulk depends on heating time and carbon nanotubes can be seen beyond 150 μm from the surface. This is confirmed by direct electron microscopy observation of large bundles as deep as about 20 μm. The composites exhibit reliable mechanical and electrical responses that are more suitable to large and repeated deformation of the polymer with respect to thermoplastic based composites, suggesting a wide potential for their application to stretchable biomedical devices. Aiming at the proposed application of artificial bladders, a bladder prototype made of poly-dimethyl siloxane endowed with a printed SWCNT-based strain sensor was developed.
