description: Loose-fitting powered air-purifying respirators (PAPRs) are used in healthcare settings, although barriers to routine, everyday usage remain, including usability concerns and potential interference with work activities. Loose-fitting PAPRs are approved by the National Institute for Occupational Safety and Health (NIOSH) and must meet minimum performance requirements, including a minimum airflow requirement of 170 L/min. One course of action to address usability concerns is to allow for the use of PAPRs designed with reduced airflow rates. The primary objective of this study was to assess the effect of PAPR flow rate and user work rate on PAPR performance, using a manikin-based assessment method. PAPR performance was quantified using “Manikin Fit Factor” (mFF), a ratio of the challenge aerosol concentration to the in-facepiece concentration. Flow rates from 50-215 L/min and low, moderate, and high work rates were tested. Two models of NIOSH Approved® loose-fitting facepiece PAPRs were tested, both having an Occupational Safety and Health Administration Assigned Protection Factor (APF), or expected level of protection, of 25. A two-way analysis of variance with an effect size model was run for each PAPR model to analyze the effects of work rate and flow rate on PAPR performance. Flow rate and work rate were found to be significant variables impacting PAPR performance. At low and moderate work rates and flow rates below the NIOSH minimum of 170 L/min, mFF was greater than or equal to 250, which is ten times the OSHA APF of 25 for loose-fitting facepiece PAPRs. At high work rates and flow rates below 170 L/min, mFF was not greater than or equal to 250. These results suggest that some loose-fitting facepiece PAPRs designed with a flow rate lower than the current NIOSH requirement of 170 L/min may provide respirator users with expected protection at low and moderate work rates. However, when used at high work rates, some loose-fitting facepiece PAPRs designed with lower flow rates may not provide the expected level of protection.

description: Atomistic tight-binding (TB) simulations are performed to calculate the Stark shift of the hyperfine coupling for a single Arsenic (As) donor in Silicon (Si). The role of the central-cell correction is studied by implementing both the static and the non-static dielectric screenings of the donor potential, and by including the effect of the lattice strain close to the donor site. The dielectric screening of the donor potential tunes the value of the quadratic Stark shift parameter ($η_2$) from -1.3 $\times$ 10$^{-3} μ$m$^2$/V$^2$ for the static dielectric screening to -1.72 $\times$ 10$^{-3} μ$m$^2$/V$^2$ for the non-static dielectric screening. The effect of lattice strain, implemented by a 3.2% change in the As-Si nearest-neighbour bond length, further shifts the value of $η_2$ to -1.87 $\times$ 10$^{-3} μ$m$^2$/V$^2$, resulting in an excellent agreement of theory with the experimentally measured value of -1.9 $\pm$ 0.2 $\times$ 10$^{-3} μ$m$^2$/V$^2$. Based on our direct comparison of the calculations with the experiment, we conclude that the previously ignored non-static dielectric screening of the donor potential and the lattice strain significantly influence the donor wave function charge density and thereby leads to a better agreement with the available experimental data sets.

description: This study provides an overview on the relationships between exposure to work-related, hand-arm vibration and the occurrence of pre-defined disorders of the hands. We searched Medline, Embase, Web of Science, Cochrane Central, and PsycINFO for cross-sectional and longitudinal studies on the association between work-related vibration exposure and the occurrence of hand-arm vibration syndrome (including vibration-induced white finger), Dupuytren’s contracture, or hypothenar hammer syndrome. We used a 16-item checklist for assessing risk of bias. We present results narratively, and we conducted random effects meta-analyses if possible. We included 10 studies with more than 24,381 participants. Our results showed statistically significant associations between the exposure to hand-arm vibrations and the occurrence of the selected disorders, with pooled odds ratios ranging between 1.35 (95% CI: 1.28 to 2.80) and 3.43 (95% CI: 2.10 to 5.59). Considerable between-study hetereogeneity was observed. Our analyses show that exposure to vibrating tools at work is associated with an increased risk for the occurrence of selected disorders of the hands. Due to the majority of studies being cross-sectional, no firm conclusion is possible regarding causal relationships between vibration exposure and disorder occurrence. Future research should specifically address whether reducing the exposure to hand-held vibrating tools at work reduces the incidence of the disorders of the hands investigated in this systematic review.

description: Questo lavoro nasce dall’esigenza di riflettere sul ruolo che l’Autonomia scolastica ha rivestito nella gestione della Scuola. Il punto di partenza è stata l’esigenza di conoscere l’evoluzione che l’autonomia scolastica ha apportato nella cultura organizzativa della scuola, nella gestione del personale e nella sua valorizzazione da parte dei Dirigenti scolastici. Una delle più rilevanti innovazioni in campo scolastico è stata indubbiamente l’attribuzione dell’Autonomia alle Istituzioni Scolastiche. Il lavoro di ricerca ha riguardato, difatti, lo sviluppo e le pratiche professionali dei Dirigenti scolastici nella gestione delle risorse umane, a seguito dell’Autonomia scolastica. Il nostro non vuole essere una formalizzazione sull’Autonomia scolastica, né vuole fornire risposte certe, affermando in quale Paese viene meglio gestita l’Autonomia scolastica, perché a nostro avviso le sistematizzazioni sono strutturate nel tempo e variano a secondo degli angoli di visuale. L’intento principale è stato quello di guardare con occhi lucidi come i Dirigenti scolastici affrontano i problemi quotidiani nella gestione delle risorse umane in Italia e in Inghilterra al fine di trarre spunti di miglioramento per il futuro. ..

Creators: name: Shoko, Lisa Nyashayashe
Publisher: name: University of Kent
Year: 2022

description: It is often that when discussing issues around race and racism within Higher Education, people ask, "where is the data?" In this thesis, I look back at some of the contemporary student decolonial movements that have happened across the UK. I share insights from these movements and the experiences of several students from the global majority - their experiences of marginalisation in higher education institutions are very common. This is the data. Drawing from data collected through interviews conducted with students engaged in decolonising efforts at the University of Kent and my own observations of events hosted by student decolonial groups involved in contemporary decolonial activism across universities in the UK, I discuss how Black People and People of Colour (BPOC) students agree that universities have done very little to support impactful and long-term changes. This has had an adverse effect on students' sense of belonging and by extension their academic outcomes, mental health, and lived experiences. Despite this, BPOC students still find a sense of belonging amongst one another. Though, this does not compensate for the gaps that universities are failing to respond to and does not apply to everyone.

description: Advanced acoustic levitation devices featuring flexible, lightweight, wide bandwidth, and film-like transducers based on ferroelectrets are designed and fabricated for sophisticated manipulation of particles in a simple way. Owing to the unique properties of ferroelectret films, such as high piezoelectric activity, very small acoustic impedance, a relatively large damping ratio, flexibility, a large area, and small density, the levitator reported features a wider bandwidth compared to ceramic-based levitators. The transportation of levitated particles is achieved by deformation of the film transducer, which represents a different and promising concept for this task.

description: Cancer creates enormous burden and is a leading cause of death in most of the countries. Esophageal cancer (EC) is one of the most common cancers in the world and has the worst survival of all cancers. Esophageal Squamous Cell Carcinoma (ESCC) and adenocarcinoma are the two main types of esophageal cancer. Exposure of polycyclic aromatic hydrocarbons (PAHs) can be cited as one of the reasons for development of Esophageal Squamous Cell Carcinoma. Toll Like Receptors (TLRs) present in human esophageal epithelial cells may pose a major role in pathogen recognition, activation of innate immunity and cancer. The study attempts to predict the role of carcinogenic PAHs in TLR4 signaling pathway and how it can ultimately result in immuno suppression and development of esophageal cancer by insilico docking evaluation. For the study we retrieved the structure of sixteen PAHs from the PubChem database and the protein model of TLR4 (PDB ID: 4G8A) from protein data bank (PDB). The binding affinity of PAHs to the TLR4 receptor was calculated using molecular docking software Auto Dock1.5. The results showed that Benzo[a]pyrene showed strong interaction toward TLR4 receptor with the highest number of polar contacts along with high binding affinity values. Considering the presence of Benzo[a] pyrene in different environmental, occupational and behavioral sources globally, there is a need for future research on the risk assessment of Benzo[a]pyrene on Esophageal Squamous Cell Carcinoma.

description: This paper explores the protection offered by the EU and the ECHR to the right to personal identity. The need to protect personal identity arises from the use of disruptive technologies (as blockchain) that allow the management of a considerable amount of data that identify a specific person (personal data). The paper explores the protection to the right of personal identity via the analysis of the case law of the ECJ and the ECtHR. The analysis of the protection offered to personal identity in the European legal order is especially critical in the occasion of the 70th anniversary of the ECHR signature and the Schuman Declaration, which could be the occasion to re-open the debate on the relationship between the EU and the ECHR.

description: This thesis investigates the fabrication and reliability of a high electron mobility transistor (HEMT) integrated circuit (IC) platform for power conversion, emphasizing the advantages of Gallium Nitride (GaN) materials in power electronics. Highlighting GaN's superior physical and electrical properties over traditional materials, this work addresses the challenges and advancements in GaN HEMT devices and GaN monolithic integrated circuits, culminating in developing an innovative IC platform that enhances device performance and reliability for power conversion applications.
This work introduces GaN applications in power electronics, discussing the benefits of GaN materials and the critical characteristics of GaN HEMT devices. It reviews the progress in GaN monolithic integrated circuits, including developing p-GaN gate fabrication processes and a novel hydrogen plasma treatment method to improve electrical properties. Chapter 2 focuses on fabricating p-GaN gate devices, comparing hydrogen plasma treatment with conventional etching processes. The chapter details the fabrication of an etched and hydrogen-treated p-GaN gate device on the same wafer. It verifies the reliability improvements of hydrogen-treated devices through various characterization methods, such as pulse testing, with explanations grounded in physical mechanisms. In Chapter 3, the thesis builds on successful device fabrication by employing Technology Computer-Aided Design simulation to model hydrogen-treated devices. The impact of the treated p-GaN layer design on device electrical characteristics are investigated. Further modeling using the ASM model and parameter optimization via IC-CAP is conducted to simulate device dynamic characteristics accurately. Circuit simulations and validation of components like capacitors, resistors, and diodes are also performed on this platform. Chapter 4 presents the monolithic integrated circuit platform based on hydrogen treatment processes, detailing the complete fabrication process, device performance, circuit module performance, and high-temperature stability of the platform. Implementing a DC-DC buck converter demonstrates the platform’s 48 V power conversion feasibility in data center applications. Chapter 5 shifts focus to emerging GaN bidirectional switches. It overviews GaN bidirectional switches, modeling, simulation analysis, and experimental results.
This thesis centers on the p-GaN gate HEMT innovation, which encompasses process development, device design, fabrication, modeling, and simulation, ultimately achieving the development of a monolithic integrated circuit platform and power conversion system. This work significantly advances the monolithic GaN power electronics by offering superior device characteristics, enhanced reliability, and improved performance through monolithic integration.

description: The FT-IR, FT-Raman and UV-Vis spectra of 4-[4-(bromo-phenylimino)-methyl]-2-ethoxy phenol (4BPMEP) were recorded and analyzed. The optimized geometrical parameters were calculated. The total energy distribution (TED) analysis was used to find the complete vibrational assignments. The UV-Vis spectra were recorded and analyzed. The hyper conjugative interaction energy E(2) and donor (i), acceptor (j) electron densities (EDs) were calculated by natural bond orbital (NBO) analysis. The band gap energy of 4BPMEP was calculated by highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) analysis. The electronic transition was studied by UV-Vis analysis of 4BPMEP with B3LYP/6-311++G(d,p) level of basis set. The non - linear optical (NLO) behavior, molecular electrostatic potential (MEP) and thermodynamic properties were also calculated. In addition, Gauge invariant atomic orbital (GIAO) method was used to calculate 1H and 13C NMR chemical shift values of 4BPMEP in the ground state at B3LYP/6-311++G(d,p) basis set. To establish the information about interactions between topoisomerase DNA gyrase enzymes and the novel compound, docking studies were carried out by Schrödinger software.

Publisher: name: Zenodo

description: Leishmaniasis is a neglected disease caused by an obligate intracellular protozoa of the genus Leishmania. The disease has different clinical manifestations, such as cutaneous, mucocutaneous and visceral leishmaniasis that depends on the infecting Leishmania species, as well as on genetics factor and the host's immune response. According to the WHO and CDC, the detection of parasite DNA through qPCR improves the sensitivity and specificity of the diagnosis, and also enables parasite quantification. Thus, an efficient and straighforward method that detect and monitors parasite load is crucial for diasease control. In this study we describe a standardized method based on qPCR for the detection and quantification of different Leishmania species in infected mammalian host cells. We were able to identify the L. braziliensis and L. guyanensis species using TaqMan technology, while SYBR Green was able to classify three groups of Leishmania. Our method also allows quantify parasites in several types of samples from different tissues of mammalian hosts. The development of a sensitive method based on qPCR for parasite load quantification can greatly improve the treatment and control of Leishmaniasis.

description: The half-life of \tsups{37}K has been measured to be $1.23651(94)~\mathrm{s}$, a value nearly an order of magnitude more precise than the best previously reported. The $β^+$ decay of \tsups{37}K occurs mainly via a superallowed branch to the ground-state of its $T=1/2$ mirror, \tsups{37}Ar. This transition has been used recently, together with similar transitions from four other nuclei, as an alternative test of CVC and method for determining $V_{ud}$, but the precision of its $ft$ value was limited by the relatively large half-life uncertainty. Our result corrects that situation. Another motivation for improving the $ft$ value was to determine the standard-model prediction for the $β$-decay correlation parameters, which will be compared to those currently being measured by the \trinat{} collaboration at \triumf. The new $ft$ value, $4605(8)~\mathrm{s}$, is now limited in precision by the $97.99(14)\%$ ground-state branching ratio.

Dabei liegt der Fokus auf den verkehrsmittelspezifischen Wegehäufigkeiten und Distanzen pro Person und Tag. Unterschiede zwischen den Gemeindegrößenklassen und Untersuchungsstädten bestätigen bisherige Befunde und Erwartungen vor allem im Verkehrsverhalten von Personen, die nur im Nahbereich unterwegs sind. Werden die Personen mit (über)regionalen Wege berücksichtigt, schwächen sich Unterschiede zwischen den Städten deutlich ab. Die Ergebnisse beschreiben die Unterschiede zwischen Gemeindetypen und zwischen Städten und umreißen so die Wirkungsbereiche kommunaler Strukturen, zu denen auch die bisherige kommunale Verkehrsplanung und Verkehrspolitik gehört.

description: The evaluation component of archaeological in urban planning finds its legal basis in European and specific national legislation of environmental assessments. The planning maps often contain the archaeological map in the themes of environmental knowledge. Generally this tool is limited at the mapping and reporting of findings in the literature, without adding information on the predicted scale. To obtain a predicted level, that can provide more accurate information to avoid impacts with the existing it is proposed the drawing up of maps of archaeological potential. These tools would be able to provide information both on the level of anthropic attending of land, also to identify "archaeologically empty" areas. Fundamental tool for the preparation of these maps are the techniques of spatial analysis conducted through the tools offered by information technology. It is the environmental assessment, measuring among others, pressure of the urban plan on the ground and the landscape, is characterized as the main tool for the evaluation of the archaeological component in the strategic development of the territory. To obtain the purpose of the research project it was required to use high analytical tools. To do it, the research has seen before the interaction and then a synthesis between the various disciplines interested, in different way, to the landscape and its history: urban planning, geography, geomorphology, ecology and archeology. A basical characteristic of the approach to landscape in fact, is an interdisciplinary approach, or rather would say transdisciplinarity: the "place" where the boundaries of different disciplines involved are broken and disciplines influence each other. For this reason it is conducted before a "semantic" job, a knowledge work towards acquiring experiences and methods typical of the various "disciplines of the landscape". The second step of the work was characterized by the synthesis of a common lexicon. It was to establish a sort of ontology is able to combine different types of knowledge in a structure containing all the relevant entities and their relationships. [edited by Author]

description: An efficient and green protocol has been introduced for the synthesis of medicinally important bis(indolyl)methane derivatives using pyruvic acid catalyst in the presence of water. Pyruvic acid catalyzes the reaction of aldehyde with indole efficiently and products were obtained in good to excellent yields under sonication (50 °C) or under conventional heating (80 °C). The advantages of this synthetic methodology are use of environmental-friendly, commercially available, biodegradable catalyst, short reaction times, Lewis acid-free and metal-free mild reaction conditions with excellent yields and is compatible with a wide range of electronically diverse substrates. Pyruvic acid in water as a catalyst under ultrasound radiation can be a better alternative to synthesize bis(indolyl)methane derivatives than some of the traditional methods.
A geometric Hamiltonian description of composite quantum systems and quantum entanglement

description: Finite-dimensional Quantum Mechanics can be geometrically formulated as a proper classical-like Hamiltonian theory in a projective Hilbert space. The description of composite quantum systems within the geometric Hamiltonian framework is discussed in this paper. As summarized in the first part of this work, in the Hamiltonian formulation the phase space of a quantum system is the Kahler manifold given by the complex projective space P(H) of the Hilbert space H of the considered quantum theory. However the phase space of a bipartite system must be given by the projective space of the tensor product of two Hilbert spaces H and K and not simply by the cartesian product P(H)xP(K) as suggested by the analogy with Classical Mechanics. A part of this paper is devoted to manage this problem. In the second part of the work, a definition of quantum entanglement and a proposal of entanglement measure are given in terms of a geometrical point of view (a rather studied topic in recent literature). Finally two known separability criteria are implemented in the Hamiltonian formalism.

description: En esta comunicación se presenta una experiencia innovadora, que demuestra lo positiva y necesaria que es la simbiosis ciudadanía-investigadores para la ciencia de la energía solar. Con una metodología altamente participativa, que llamamos “Ciencia ciudadana para la ciencia ciudadana", el equipo logró desarrollar “Generation Solar”, una webapp que crea una base de datos de instalaciones solares descentralizadas. Nuestro enfoque consistió en un proceso participativo que incluyó i) una convocatoria abierta a los investigadores para obtener sus aportes sobre qué pueden contribuir a la sociedad con su trabajo y cómo la ciudadanía pueden colaborar activamente en su investigación; ii) una hackathon online que reunió a 62 participantes de 15 países para diseñar un proyecto de ciencia ciudadana, y que dio lugar a la presentación de 12 propuestas de ciencia ciudadana únicas en el ámbito de la energía solar; iii) un proceso de evaluación que valoró las propuestas y seleccionó una ganadora y iv) el desarrollo, lanzamiento y difusión de la iniciativa de ciencia ciudadana ganadora para que fuera adoptada por la comunidad académica en el campo de la energía solar. La aplicación cuenta ya con más de 22MW de energía solar reportados, 71 instalaciones, y se prevén al menos cinco usos de investigación para los datos recogidos. La presentación hace parte del Congreso Iberoamericano de Ciencia Abierta 2022.

description: In this work, magnetic mesoporous silica-alumina composites (MSA) containing three metal oxides(MSA/MO) with different molar ratio of Si to Al (0.5, 1 and 2) were synthesized. The efficiency of prepared catalysts was compared with modified natural zeolite (ferrierite) in the multicomponent synthesis of indeno[1,2-b]indole-9,10-diones. Immobilization of ZnO, CuO and NiO on magnetic composites increased their Lewis acidic sites and improved their catalytic activity. Also magnetic property of designed catalysts enhanced their capability and easy separation. Among the mentioned composites, the catalyst with the molar ratio of S/A = 2 show the best efficiency in the synthesis of indeno[1,2-b]indole-9,10-diones under thermal conditions and water as green solvent. FT-IR, XRD, FE-SEM, EDX, elemental mapping, BET and VSM techniques were used to characterize the prepared composites. The synthesized products were obtained in high to excellent yields and their structures were confirmed by 1HNMR, 13CNMR and FT-IR spectroscopy.

Phase Mixing of Alfvén Waves Near a 2D Magnetic Null Point
Creators: name: McLaughlin, J. A.
Publisher: name: arXiv
Year: 2014
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The propagation of linear Alfvén wave pulses in an inhomogeneous plasma near a 2D coronal null point is investigated. When a uniform plasma density is considered, it is seen that an initially planar Alfvén wavefront remains planar, despite the varying equilibrium Alfvén speed, and that all the wave collects at the separatrices. Thus, in the non-ideal case, these Alfvénic disturbances preferentially dissipate their energy at these locations. For a non-uniform equilibrium density, it is found that the Alfvén wavefront is significantly distorted away from the initially planar geometry, inviting the possibility of dissipation due to phase mixing. Despite this however, we conclude that for the Alfvén wave, current density accumulation and preferential heating still primarily occur at the separatrices, even when an extremely non-uniform density profile is considered.

title: Analyse des Einflusses verschiedener Arbeitspunkte auf die wirkleistungsabhängige Spannungssensitivität an einem Mittelspannungsnetzknoten
Creators: name: Hartweg, Johanna
Publisher: name: Ostbayerische Technische Hochschule Regensburg
Year: 2022

description: Im Rahmen dieser Arbeit erfolgt die Untersuchung der wirkleistungsabhängigen Spannungssensitivität an den Knoten eines Mittelspannungsnetzstranges. Hierfür wird eine Reihe von Arbeitspunkten durch die Variation der Wirkleistungsentnahmen bzw. Einspeisungen an den Netzknoten sowie des Verschiebungsfaktors und der Spannungssollwertvorgabe am Bilanzknoten erzeugt. Die Ergebnisse zeigen eine direkte Abhängigkeit von der Spannung des untersuchten Netzknotens. Hierbei steigt die Sensitivität bei fallenden Spannungswerten. Diese können sowohl durch Wirk- und Blindleistungsbelastungen als auch durch eine veränderte Referenzspannung am Umspannwerk bedingt werden. Darüber hinaus liegt eine Beeinflussung durch die Wirkleistungsbelastung und deren Verteilung über den Netzstrang hinweg vor. Je höher die Belastung der Leitung bis zum Knoten der Flexibilität ausfällt sowie je stärker sich die Last hin zu diesem Punkt verlagert, desto höher ist die Sensitivität. Dies gilt ebenfalls für Arbeitspunkte mit gleichbleibender Spannung in den betrachteten Knoten. Des Weiteren wird die Anpassung eines multiplen linearen Regressionsmodells vorgenommen. Dieses ermöglicht eine Abschätzung der Sensitivitätswerte durch die Kenntnis einiger, die Belastungssituation des Netzes bestimmender Parameter.
