description: A stochastic theory is presented for a quantum vortex that is expected to occur in superfluids coated on two dimensional sphere $ {\rm S}^2 $. The starting point is the canonical equation of motion (the Kirchhoff equation) for a point vortex, which is derived using the time-dependent Landau-Ginzburg theory. The vortex equation, which is equivalent to the spin equation, turns out to be the Langevin equation, from which the Fokker-Planck equation is obtained by using the functional integral technique. The Fokker-Planck equation is solved for several typical cases of the vortex motion by noting the specific form of pinning potential. An extension to the non-spherical vortices is briefly discussed for the case of the vortex on plane and pseudo-sphere.

description: Background: Despite the benefit and promotion of exclusive breast feeding, the rate of excusive breast feeding is still low in Ethiopia. Thus, this study will assess factors that lead to non- adherence to exclusive breast feeding among HIV positive mothers. Objective: the main objective of this study was to assess the prevalence of exclusive breast feeding and factors that influence its practices among HIV positive mothers of infants aged 6-24 months old who are on chronic HIV care in selected health facilities of Adama town. Method: Institution based cross-sectional study was conducted among 193 HIV positive women with infant aged 6-24months in three health facilities (Adama hospital, Geda and Adama health centers) of Adama town in Ethiopia. Data was collected using structured and pre-tested questionnaires. Four data collectors and three supervisors were trained and involved in data collection process. Data were entered and analyzed using SPSS version 20 statistical software package. Univariate analyses were done to determine various proportions and bivariate analysis was conducted to measure the existence and the strength of an association between the dependent and the independent variables. Level of significance was set at a p value of ≤ 0.05. Variables that had less than 0.05 level of significance were further analyzed in multiple logistic regression models to control the potential confounding variables.

description: We study the states of one and two atoms in a rotating ring lattice in a Hubbard type tight-binding model. The model is developed carefully from basic principles in order to properly identify the physical observables. The one-particle ground state may be degenerate and represent a finite flow velocity depending on the parity of the number of lattice sites, the sign of the tunneling matrix element, and the rotation speed of the lattice. Variation of the rotation speed may be used to control one-atom states, and leads to peculiar behaviors such as wildly different phase and group velocities for an atom. Adiabatic variation of the rotation speed of the lattice may also be used to control the state of a two-atom lattice dimer. For instance, at a suitably chosen rotation speed both atoms are confined to the same lattice site.

description: ObjectivePlay is a non-invasive, safe and inexpensive intervention that can help paediatric patients and their families manage difficult aspects of being ill or hospitalised. Although play has existed in hospitals for decades, research on hospital play interventions is scarce. This review aimed to categorise and synthesise the last 20 years of research on hospital play interventions.DesignScoping review.Data sourcesPubMed, CINAHL, CENTRAL, ERIC and PsycINFO (1 January 2000- 9 September 2020).Study selection and data extractionWe systematically searched for original peer-reviewed articles, written in English, on hospital play interventions in paediatric patients (0-18 years) in non-psychiatric settings. Two reviewers independently screened titles and abstracts, reviewed full text of relevant articles and extracted data. We thematically synthesised the data from the included studies, and a descriptive analysis, based on a developed framework, is presented.ResultsOf the 297 included articles, 78% came from high-income countries and 56% were published within the last 5 years. Play interventions were carried out across all ages by various healthcare professionals. Play interventions served different roles within four clinical contexts: A) procedures and diagnostic tests, B) patient education, C) treatment and recovery and D) adaptation. Across these contexts, play interventions were generally facilitated and purpose-oriented and had positive reported effects on pain, stress, and anxiety.ConclusionsPlay in hospitals is an emerging interdisciplinary research area with a significant potential benefit for child and family health. Future research should further describe principles for play in hospitals. High-quality studies investigating short-term and long-term effects are needed to guide when and how to best integrate play in hospitals.

description: Molecular organic fluorophores are currently used in organic light-emitting diodes, though non-emissive triplet excitons generated in devices incorporating conventional fluorophores limit the efficiency. This limit can be overcome in materials that have intramolecular charge-transfer excitonic states and associated small singlet-triplet energy separations; triplets can then be converted to emissive singlet excitons resulting in efficient delayed fluorescence. However, the mechanistic details of the spin interconversion have not yet been fully resolved. We report transient electron spin resonance studies that allow direct probing of the spin conversion in a series of delayed fluorescence fluorophores with varying energy gaps between local excitation and charge-transfer triplet states. The observation of distinct triplet signals, unusual in transient electron spin resonance, suggests that multiple triplet states mediate the photophysics for efficient light emission in delayed fluorescence emitters. We reveal that as the energy separation between local excitation and charge-transfer triplet states decreases, spin interconversion changes from a direct, singlet-triplet mechanism to an indirect mechanism involving intermediate states.

description: Stress-activated protein kinases (SAPK) are associated with sensorineural hearing loss (SNHL) of multiple etiologies. Their activity is tightly regulated by dual-specificity phosphatase 1 (DUSP1), whose loss of function leads to sustained SAPK activation. Dusp1 gene knockout in mice accelerates SNHL progression and triggers inflammation, redox imbalance and hair cell (HC) death. To better understand the link between inflammation and redox imbalance, we analyzed the cochlear transcriptome in Dusp1−/− mice. RNA sequencing analysis (GSE176114) indicated that Dusp1−/− cochleae can be defined by a distinct profile of key cellular expression programs, including genes of the inflammatory response and glutathione (GSH) metabolism. To dissociate the two components, we treated Dusp1−/− mice with N-acetylcysteine, and hearing was followed-up longitudinally by auditory brainstem response recordings. A combination of immunofluorescence, Western blotting, enzymatic activity, GSH levels measurements and RT-qPCR techniques were used. N-acetylcysteine treatment delayed the onset of SNHL and mitigated cochlear damage, with fewer TUNEL+ HC and lower numbers of spiral ganglion neurons with p-H2AX foci. N-acetylcysteine not only improved the redox balance in Dusp1−/− mice but also inhibited cytokine production and reduced macrophage recruitment. Our data point to a critical role for DUSP1 in controlling the cross-talk between oxidative stress and inflammation.
title: Oceans of Feeling: An Emotional History of Caribbean Migrants in Postwar Britain
Creators: name: Tristram-Walmsley, Ryan
Publisher: name: University of Kent
Year: 2023

description: This thesis is set to analyse the emotional experiences and expressions of Caribbean migrants to Britain in the postwar period, from their motivations to emigrate through to the strategies of affective attainment, adjustment, and resistance which they practised once arrived. In so doing, it works within the paradigm of E. P. Thompson’s “history from below” and utilises the conceptual approaches and theoretical tools of the history of emotions. It has laboured under the belief that, in working on an extensively-researched topic in such a way, we can uncover novel and meaningful insights – insights into how feelings were at the core of historical change here, and how they shaped and transformed the historical narrative at every turn. This ranged from the ways in which emotions acted as the fundamental generative principle for motivations to migrate, resided at the core of the racist practices which they experienced upon arrival, and conditioned the spatial landscapes of refuge which they created in response to this. In accomplishing this, this thesis makes use of a wide range of different source material – including original oral history interviews conducted by the author – arguing that the cultural and artistic output of historical actors are critical in understanding their emotional experiences. Ultimately, this thesis presents an emotional history of Caribbean migrants in postwar by injecting emotions and felt experience, for the first time, into this historical narrative through five thematically-structured chapters.

description: Small construction contractors are vital for provision of infrastructures in Addis Ababa.

The study is inspired by common low growth or business failures witnessed among this

class of business. The main objective of the study is to examine growth challenges facing

small construction contractors in Addis Ababa. Data were collected from both primary

and secondary sources. The main instrument of data collection was the questionnaire and

supported by interview. Questionnaires were dispatched to random samples of small

construction contractors in Addis Ababa. Accordingly, 120 completed questionnaires

were returned. Data was then analyzed by using descriptive statistics and factor analysis.

The result revealed that small construction contractors have relatively heavy proportion

and participation in basic infrastructure development which are essential for economic

growth of the city

description: The phase stability of the (Bi2)m(Bi2Te3)n natural superlattices has been investigated through the low temperature solid state synthesis of a number of new binary BixTe1-x compositions. Powder X-ray diffraction revealed that an infinitely adaptive series forms for 0.44 < x < 0.70, while an unusual 2-phase region with continuously changing compositions is observed for 0.41 < x < 0.43. For x > 0.70, mixtures of elemental Bi and an almost constant composition (Bi2)m(Bi2Te3)n phase are observed. Rietveld analysis of synchrotron X-ray powder diffraction data collected on Bi2Te (m = 2, n = 1) revealed substantial interchange of Bi and Te between the Bi2 and Bi2Te3 blocks, demonstrating that the block compositions are variable. All investigated phase pure compositions are degenerate semiconductors with low residual resistivity ratios and moderate positive magnetoresistances (R/R0 = 1.05 in 9 T). The maximum Seebeck coefficient is +80 muV K-1 for x = 0.63, leading to an estimated thermoelectric figure of merit, zT = 0.2 at 250 K.

description: The goal of all sequencing techniques is to provide possible identities for genes, map the entire genome of an organism, and discover novel genes or even novel organisms. Downstream processing of sequencing results is essential to achieve these goals. Bioinformatics combines the principles of biological and computer science, aiming to collect, store, analyze, and provide access to biological data such as nucleic acid and amino acid sequences. Using bioinformatics, a large amount of information on molecular biology can be organized to provide standardized data and used by researchers worldwide to design tools for the analysis of these data and to give an accurate and meaningful interpretation of the information.

description: The starting point of this paper is a system described in form of a UML class diagram where system states are characterized by OCL invariants and system transitions are defined by OCL pre- and postconditions. The aim of our approach is to assist the developer in learning about the consequences of the described system states and transitions and about the formal implications of the properties that are explicitly given. We propose to draw conclusions about the stated constraints by translating the UML and OCL model into the algebraic specification language and system Maude, which is based on rewrite logic. We will concentrate in this paper on employing Maude's capabilities for state search. Maude's state search offers the possibility to describe a start configuration of the system and then explore all configurations reachable by rewriting. The search can be adjusted by formulating requirements for the allowed states and the allowed transitions.

description: Some core-collapse supernovae appear to be hyper-energetic, and a subset of these are aspherical and associated with long GRBs. We use observations of electromagnetic emission from core-collapse supernovae and GRBs to impose constraints on their free energy source as a prior to searches for their gravitational wave emission. We review these events based on a finite efficiency for the conversion of spin energy to magnetic winds powering supernovae. We find that some of the hyper-energetic events cannot be powered by the spindown of rapidly rotating proto-neutron stars by virtue of their limited rotational energy. They can, instead, be produced by the spindown of black holes providing a distinct prospect for gravitational-wave emission of interest to LIGO, Virgo, and the LCGT.

description: Motivated by recent experiments [Vera-Marun et al., arXiv:1109.5969], we formulate a non-linear theory of spin transport in quantum coherent conductors. We show how a mesoscopic constriction with energy-dependent transmission can convert a spin current injected by a spin accumulation into an electric signal, relying neither on magnetic nor exchange fields. When the transmission through the constriction is spin-independent, the spin-charge coupling is non-linear, with an electric signal that is quadratic in the accumulation. We estimate that gated mesoscopic constrictions have a sensitivity that allows to detect accumulations much smaller than a percent of the Fermi energy.

description: La croissance démographique provoque une hausse des besoins humains (énergie, nourriture, services, etc) dont la satisfaction engendre des problèmes environnementaux et sociaux.

Il appartient à chaque Etat de prendre des dispositions pour lutter contre une évolution exponentielle de sa population ; surtout que celle-ci ne va pas de pair avec l'augmentation des moyens des subsistances. Parmi les mesures préconisées par le gouvernement de la République démocratique du Congo pour maîtriser cette augmentation, il y a les pratiques contraceptives. Cependant la pose d'implant vulgarisée parmi lesdites pratiques crée une crise sociale dans le quartier Mudikwiti, et mérite d'être repensée.

description: Super-Eddington accretion is very efficient in growing the mass of a black hole: in a fraction of the Eddington time its mass can grow to an arbitrary large value if the feedback effect is not taken into account. However, since super-Eddington accretion has a very low radiation efficiency, people have argued against it as a major process for the growth of the black holes in quasars since observations have constrained the average accretion efficiency of the black holes in quasars to be $\ga 0.1$. In this paper we show that the observational constraint does not need to be violated if the black holes in quasars have undergone a two-phase growing process: with a short super-Eddington accretion process they get their masses inflated by a very large factor until the feedback process becomes important, then with a prolonged sub-Eddington accretion process they have their masses increased by a factor $\ga 2$. The overall average efficiency of this two-phase process is then $\ga 0.1$, and the existence of black holes of $10^9 M_\odot$ by redshift 6 is easily explained. Observational test of the existence of the super-Eddington accretion phase is briefly discussed.

description: A dc electric current can be induced in a hybrid semiconductor-superconductor system under illumination it by a circularly polarized light with the frequency below the energy of semiconductor interband transitions. In conditions when the light beam is unable to create real electron-hole excitations, this phenomenon is reminiscent of the Meissner effect in the static magnetic field. Such an effect can be employed in systems combining cavity photons and superconducting quantum circuits.

description: This dissertation describes the interviews we conducted in late 2021 with 1 representative for each of the 19 disciplinary areas within the department of Classical Philology and Italian Studies (FICLIT) at the University of Bologna. The answers we gathered from participants were analysed using a Grounded Theory approach and allowed us to reflect on the definition of the word "data" in the humanities domain, what research materials should be considered to fall within this definition, and what researchers in this field think of the term. In addition, we gathered information on other aspects of research, such as methodologies, possible copyright and privacy concerns, preservation strategies, and more.
First, we extracted a list of 16 research materials that constitute the "building blocks" of research in the humanities, as far as our interviewees are concerned; publications emerged as the most important one. The majority of participants included most of the materials they use in research within their definition of data, and this term did not seem to be especially problematic for them, contrary to what has been reported elsewhere. Most researchers also stated they have a precise methodology, although rarely formalised, which is surprising when compared to the available literature. Regarding data management practices, our results mostly confirm what emerged from previous studies, but collaboration was a notable exception: sharing with colleagues, and teamwork appear more common than reported elsewhere. Finally, the attitudes towards open science and open data are mostly positive among the interviewees.
The study should be replicated on a larger scale, and include other disciplines, to confirm these findings and paint a more precise picture of how research is done in the humanities and how it can be made more FAIR (findable, accessible, interoperable and re-usable).

description: This study assesses the knowledge levels of mothers regarding diarrhea and their strategies for the prevention and management of diarrhea among children under the age of five. Quantitative research methods were used through purposive study. The study is based on two objective which is to find out the difference between educated and non-educated mothers; the relationship between knowledge and strategies for prevention of diarrheal diseases among under five (5) children in Bauchi State. Literature was reviewed on the Concept and types of Diarrheas; an empirical study was done. The population of the study consists of 792 mothers with under-five years children; data was collected through questionnaire using 5-point likert scale and sample t-test and PPMC was used for data analysis The findings reveal that there is a significant relationship between knowledge and practice of diarrheal management among mothers of under-five children in Azare metropolis, Bauchi State. Mothers employ a variety of preventive and management strategies, including improved hygiene practices, home remedies, and traditional healing methods. However, the study highlights the importance of providing mothers with accurate and evidence-based information on diarrhea prevention and management. The study found out there is significant relationship between Knowledge and practice of management against diarrhea disease and management strategies against diarrheal disease. The study recommends need for targeted educational interventions that empower mothers with the knowledge and skills required to prevent and manage diarrhea effectively. Community-based health programs should focus on disseminating accurate information on exclusive breastfeeding, ORT, and the importance of seeking timely medical care. Additionally, efforts should be made to address the specific challenges faced by mothers in rural and disadvantaged communities.

description: The thermodynamic properties of the superconducting state induced in metallic molecular hydrogen under the influence of pressure 347 GPa were determined. In particular, it has been shown that the critical temperature ($T_{C}$) changes in the range from 120 K to 90 K for $μ^{*}\in<0.08,0.15>$, where $μ^{*}$ is the value of the Coulomb pseudopotential. Next, the energy gap near the temperature of zero Kelvin ($2Δ(0)$) was calculated. It has been stated, that the dimensionless ratio $2Δ(0)/k_{B}T_{C}$ slightly decreases with the increase of $μ^{*}$ from 3.98 to 3.84. In the last step, the ratio of effective electron mass ($m^{*}_{e}$) to the bare electron mass ($m_{e}$)) was determined. It has been proved that $m^{*}_{e}/m_{e}$ takes its highest value equal to 1.96 for $T=T_{C}$.

description: We report calculation of heat capacity of an attractive Bose-Einstein condensate, with the number N of bosons increasing and eventually approaching the critical number Ncr for collapse, using the correlated potential harmonics (CPH) method. Boson pairs interact via the realistic van der Waals potential. It is found that the transition temperature Tc increases initially slowly, then rapidly as N becomes closer to Ncr . The peak value of heat capacity for a fixed N increases slowly with N, for N far away from Ncr . But after reaching a maximum, it starts decreasing when N approaches Ncr . The effective potential calculated by CPH method provides an insight into this strange behavior.

Remarks. Attheyella (Chappuisiella) hirsuta was established by Chappuis (1951) based on two specimens of each sex collected from a moss sample obtained by a waterfall along Guide River in Tasmania. Hamond (1987) subsequently redescribed in detail this species (as Canthocamptus hirsutus) based on specimens associated with wet moss samples collected from the type locality and inland waters of Victoria. As A. (Ch.) hirsuta was hitherto known only from Tasmania and Victoria, its collection in Western Australia represents a large range extension for this freshwater taxon. Furthermore, this is the first record of this species from ground waters.

description: Yellow and red supergiants are evolved massive stars whose numbers and locations on the HR diagram can provide a stringent test for models of massive star evolution. Previous studies have found large discrepancies between the relative number of yellow supergiants observed as a function of mass and those predicted by evolutionary models, while a disagreement between the predicted and observed locations of red supergiants on the HR diagram was only recently resolved. Here we extend these studies by examining the yellow and red supergiant populations of M33. Unfortunately, identifying these stars is difficult as this portion of the color-magnitude diagram is heavily contaminated by foreground dwarfs. We identify the red supergiants through a combination of radial velocities and a two-color surface gravity discriminant and, after re-characterizing the rotation curve of M33 with our newly selected red supergiants, we identify the yellow supergiants through a combination of radial velocities and the strength of the OI $λ$7774 triplet. We examine ~1300 spectra in total and identify 121 yellow supergiants (a sample which is unbiased in luminosity above log(L/L\odot) ~ 4.8) and 189 red supergiants. After placing these objects on the HR diagram, we find that the latest generation of Geneva evolutionary tracks show excellent agreement with the observed locations of our red and yellow supergiants, the observed relative number of yellow supergiants with mass and the observed red supergiant upper mass limit. These models therefore represent a drastic improvement over previous generations.

Remarks. Elaphoidella bidens (Schmeil, 1894) is a cosmopolitan species that typically inhabits the littoral zone of large waterbodies (Gurney 1932; Lewis 1972). In Australia, this species is known to occur commonly in slow-moving streams or lakes in South Australia, Victoria, New South Wales and Queensland (Hamond 1987). The presence of E. bidens from the Gnangara Mound region, accordingly, represents the first record of this species in Western Australia. Although the occurrence of this species in ground waters of Western Australia is unusual, it is certainly not unique, as it has been reported previously from caves in the Ryukyu Islands of Japan (Miura 1962b) and North America (Reeves et al. 2000).

description: Accurate distances to pulsars can be used for a variety of studies of the Galaxy and its electron content. However, most distance measures to pulsars have been derived from the absorption (or lack thereof) of pulsar emission by Galactic HI gas, which typically implies that only upper or lower limits on the pulsar distance are available. We present a critical analysis of all measured HI distance limits to pulsars and other neutron stars, and translate these limits into actual distance estimates through a likelihood analysis that simultaneously corrects for statistical biases. We also apply this analysis to parallax measurements of pulsars in order to obtain accurate distance estimates and find that the parallax and HI distance measurements are biased in different ways, because of differences in the sampled populations. Parallax measurements typically underestimate a pulsar's distance because of the limited distance to which this technique works and the consequential strong effect of the Galactic pulsar distribution (i.e. the original Lutz-Kelker bias), in HI distance limits, however, the luminosity bias dominates the Lutz-Kelker effect, leading to overestimated distances because the bright pulsars on which this technique is applicable are more likely to be nearby given their brightness.
