description: We present an analysis of the mass distribution in the region of the Galactic bulge, which leads to constraints on the total amount and distribution of Dark Matter (DM) therein. Our results -based on the dynamical measurement of the BRAVA collaboration- are quantitatively compatible with those of a recent analysis, and generalised to a vaste sample of observationally inferred morphologies of the stellar components in the region of the Galactic bulge. By fitting the inferred DM mass to a generalised NFW profile, we find that cores (index gamma smaller than 0.6) are forbidden only for very light configurations of the bulge, and that cusps (index gamma bigger than 1.2) are allowed, but not necessarily preferred. Interestingly, we find that the results for the bulge region are compatible with those obtained with dynamical methods (based on the rotation curve) applied to outer regions of the Milky Way, for all morphologies adopted. We find that the uncertainty on the shape of the stellar morphology heavily affects the determination of the DM distribution in the bulge region, which is gravitationally dominated by baryons, adding up to the uncertainty on its normalization. The combination of the two hinders the actual possibility to infer sound conclusions about the distribution of DM in the region of the Galactic bulge, and only future observations of the stellar census and dynamics in this region will bring us closer to a quantitatively more definite answer.

description: Children with Cystic Fibrosis (CF) must undergo long-term and invasive treatment regimes. Research indicates that the emotional impact of invasive procedures associated with treatment are significantly stressful for the child-patient and his or her family. It is also documented that procedural play can significantly reduce these stress levels. Nurses are one of the primary health care professionals responsible for dealing with hospitalised children with CF. It is important that they are aware of the significant therapeutic role of procedural play. There is limited literature on nurses' understanding of procedural play in the acute paediatric environment. Thus, the purpose of this study is to describe factors, from a nursing perspective, that facilitate or inhibit the integration of play as a therapeutic tool for children undergoing invasive procedures for the treatment of CF in the context of an acute paediatric ward culture. Using qualitative, descriptive phenomenological research methods seventeen registered nurses from four Australian hospitals were interviewed. The unstructured, open style interviews were transcribed verbatim and thematically analysed. Key findings showed that whilst nurses had an intuitive understanding of play they did not have a professional discourse of procedural play. The hospital system supports the prioritisation of clinical practice over the child's psychosocial needs during procedural interventions. This research makes an original contribution to the knowledge base in the field of paediatrics by providing insights into an important and unexplored area. The thesis details strong recommendations with regards to developing a supportive sub-culture of procedural play through educational strategies for the nursing profession.

description: Uranus and Neptune exhibit fast surface zonal winds that can reach up to few hundred meters per second. Previous studies on zonal gravitational harmonics and Ohmic dissipation constraints suggest that the wind speeds diminish rapidly in relatively shallow depths within the planets. Through a case-by-case comparison between the missing dynamical gravitational harmonic $J^\prime_4$ from structure models, and with that expected from fluid perturbations, we put constraints on zonal wind decay in Uranus and Neptune. To this end, we generate polytropic empirical structure models of Uranus and Neptune using $4^{\rm th}$-order Theory of Figures (ToF) that leave hydrostatic $J_4$ as an open parameter. Allotting the missing dynamical contribution to density perturbations caused by zonal winds (and their dynamic self-gravity), we find that the maximum scale height of zonal winds are $\sim 2-3\%$ of the planetary radii for both planets. Allowing the models to have $J_2$ solutions in the $\pm 5 \times 10^{-6}$ range around the observed value has similar implications. The effect of self-gravity on $J^\prime_4$ is roughly a factor of ten lower than that of zonal winds, as expected. The decay scale heights are virtually insensitive to the proposed modifications to the bulk rotation periods of Uranus and Neptune in the literature. Additionally, we find that the dynamical density perturbations due to zonal winds have a measurable impact on the shape of the planet, and could potentially be used to infer wind decay and bulk rotation period via future observations.

description: We have developed a microfluidic tool to measure the diffusion coefficient $D$ of solutes in an aqueous solution, by following the temporal relaxation of an initially steep concentration gradient in a microchannel. Our chip exploits multilayer soft lithography and the opening of a pneumatic microvalve to trigger the interdiffusion of pure water and the solution initially separated in the channel by the valve, the so-called free interface diffusion technique. Another microvalve at a distance from the diffusion zone closes the channel and thus suppresses convection. Using this chip, we have measured diffusion coefficients of solutes in water with a broad size range, from small molecules to polymers and colloids, with values in the range $D \in [10^{-13}- 10^{-9}]$~m$^2$/s. The same experiments but with added colloidal tracers also revealed diffusio-phoresis and diffusio-osmosis phenomena due to the presence of the solute concentration gradient. We nevertheless show that these interfacial-driven transport phenomena do not affect the measurements of the solute diffusion coefficients in the explored concentration range.

description: A charged compact star models have been determined for anisotropic fluid distribution. We have solved the Einstein's- Maxwell field equations to construct the charged compact star models by using radial pressure, metric function $e^λ$ and electric charge function. The generic charged anisotropic solution is verified by exploring different physical conditions like, causality condition, mass-radius relation and stability of the solution (via. adiabatic index, TOV equations and Herrera cracking concept). It is observed that the present charged anisotropic compact star is compatible with the star PSR 1937+21. However we also presented the EOS $ρ=f(p)$ for present charged compact star model.

description: NA60+ is a fixed target experiment proposed in the framework of the Physics Beyond Colliders programme at CERN. It aims to precisely measure the hard and electromagnetic probes in nuclear collisions. Initially proposed for the underground cavern ECN3 with very high beam intensities, the experiment now foresees a location in the EHN1 surface hall which was shown to have a limited impact on the physics performance in spite of a significant reduction of beam intensity and detector size. The potential installation and operation of the experiment with the ion beams from the Super Proton Synchrotron (SPS) has been examined regarding detector integration, beam physics, radiation protection and shielding requirements. The integration of the experiment is considered feasible, but would require a significant reconfiguration of the existing hall infrastructure with regards to shielding and layout.

description: This paper is focused on the functional renormalization group applied to the $T_5^6$ tensor model on the Abelian group $U(1)$ with closure constraint. For the first time, we derive the flow equations for the couplings and mass parameters in a suitable truncation around the marginal interactions with respect to the perturbative power counting. For the second time, we study the behavior around the Gaussian fixed point, and show that the theory is nonasymptotically free. Finally, we discuss the UV completion of the theory. We show the existence of several nontrivial fixed points, study the behavior of the renormalization group flow around them, and point out evidence in favor of an asymptotically safe theory.

description: Quasar-galaxy pairs at small separations are important probes of gas flows in the disk-halo interface in galaxies. We study host galaxies of 198 MgII absorbers at $0.39\le z_{abs}\le1.05$ that show detectable nebular emission lines in the SDSS spectra. We report measurements of impact parameter (5.9$\le D[kpc]\le$16.9) and absolute B-band magnitude ($-18.7\le {\rm M_B}\le -22.3$ mag) of host galaxies of 74 of these absorbers using multi-band images from the DESI Legacy Imaging Survey, more than doubling the number of known host galaxies with $D\le17$ kpc. This has allowed us to quantify the relationship between MgII rest equivalent width($W_{2796}$) and D, with best-fit parameters of $W_{2796}(D=0) = 3.44\pm 0.20$ Angstrom and an exponential scale length of 21.6$^{+2.41}_{-1.97}$ $kpc$. We find a significant anti-correlation between $M_B$ and D, and $M_B$ and $W_{2796}$, consistent with the brighter galaxies producing stronger MgII absorption. We use stacked images to detect average emissions from galaxies in the full sample. Using these images and stacked spectra, we derive the mean stellar mass ($9.4\le log(M_*/M_\odot) \le 9.8$), star formation rate ($2.3\le{\rm SFR}[M_\odot yr^{-1}] \le 4.5$), age (2.5$-$4 Gyr), metallicity (12+log(O/H)$\sim$8.3) and ionization parameter (log~q[cm s$^{-1}$]$\sim$ 7.7) for these galaxies. The average $M_*$ found is less compared to those of MgII absorbers studied in the literature. The average SFR and metallicity inferred are consistent with that expected in the main sequence and the known stellar mass-metallicity relation, respectively. High spatial resolution follow-up spectroscopic and imaging observations of this sample are imperative for probing gas flows close to the star-forming regions of high-$z$ galaxies.

Palliative care services for Indian migrants in Australia: a constructivist grounded theory study of experiences of the family members of terminally ill patients

description: The current global health care system faces a massive challenge in providing needs-based care to people, particularly in the palliative care setting. Presently, palliative care focuses on comprehensive care not only for the patient, but also for their families and caregivers. The palliative care approach aims to improve the quality of life of individuals facing a life-threatening illness and their families, by preventing and relieving suffering through early identification and by assessment and treatment of pain and other problems related to physical, psychosocial and spiritual factors. This approach facilitates identification of the wishes of patients and their families about care throughout a period of declining health and especially during end-of-life care (World Health Organization, 2003). Changing patterns in the care of terminally ill people, and a preference for death at home, mean there is heavy reliance on family caregivers to provide the majority of the care needed. The main purpose of this study was to explore the experiences of the family members of terminally ill Indian patients in Victoria, Australia. This study used a constructivist grounded theory approach. The study was conducted in two major health care providers of Melbourne, an inpatient service and a home-based service. Convenience and snowball sampling techniques were used to recruit the participants. In total, six participants were recruited for the study and data was gathered by using semi-structured interviews. A grounded theory coding was used to analyse the data and three major themes were identified. They were experiences of health system issues; cultural issues; and caring experiences. The study identified that caring for terminally ill people is hard work for the family members and they faced many cultural issues while accessing palliative care services in in-patient palliative care services. The main cultural issues were food, clothing, religious practices and aspects of death and dying. Australia is a multicultural country; it is therefore essential that culturally competent care is incorporated in palliative care practice to improve quality of life at the end of life for all who require such care.

description: We first present the multicolor photometry results of the rapidly rotating magnetic star HD 345439 using the Nanshan One-meter Wide-field Telescope. From the photometric observations, we derive a rotational period of 0.7699\pm0.0014 day. The light curves of HD 345439 are dominated by the double asymmetric S-wave feature that arises from the magnetic clouds. Pulsating behaviors are not observed in Sector 41 of the Transiting Exoplanet Survey Satellite. No evidence is found of the occurrence of centrifugal breakout events neither in the residual flux nor in the systematic variations at the extremum of the light curve. Based on the hypothesis of the Rigidly Rotating Magnetosphere model, we restrict the magnetic obliquity angle {$β$} and the rotational inclination angle $i$ so that they satisfy the approximate relation {$β+ i \approx 105^{\circ}$}. The colour excess, extinction, and luminosity are determined to be $E_{(B-V)}=0.745\pm0.016\,$mag, $A_{V}=2.31\pm0.05\,$mag, and $\rm log\,(L/L_{\odot})=3.82\pm0.1 $dex, respectively. Furthermore, we derive the effective temperature as $T$$\rm _{eff}=22\pm1 $kK and the surface gravity as log$g=4.00\pm0.22$. The mass$ M=7.24_{-1.24}^{+1.75}\rm M_{\odot}$, radius$ R=4.44_{-1.93}^{+2.68}\rm R_{\odot}$, and age$\rm τ_{age}=23.62\,_{-21.97}^{+4.24} $Myr are estimated from the Hertzsprung--Russell Diagram

description: We present Hubble Space Telescope imaging of 14 gas-rich, low surface brightness galaxies in the field at distances of 25-36 Mpc, with mean effective radii and $g$-band central surface brightnesses of 1.9 kpc and 24.2 mag arcsec$^{-2}$. Nine meet the standard criteria to be considered ultra-diffuse galaxies (UDGs). An inspection of point-like sources brighter than the turnover magnitude of the globular cluster luminosity function and within twice the half-light radii of each galaxy reveals that, unlike those in denser environments, gas-rich, field UDGs host very few old globular clusters (GCs). Most of the targets (nine) have zero candidate GCs, with the remainder having one or two candidates each. These findings are broadly consistent with expectations for normal dwarf galaxies of similar stellar mass. This rules out gas-rich, field UDGs as potential progenitors of the GC-rich UDGs that are typically found in galaxy clusters. However, some in galaxy groups may be directly accreted from the field. In line with other recent results, this strongly suggests that there must be at least two distinct formation pathways for UDGs, and that this sub-population is simply an extreme low surface brightness extension of the underlying dwarf galaxy population. The root cause of their diffuse stellar distributions remains unclear, but the formation mechanism appears to only impact the distribution of stars (and potentially dark matter), without strongly impacting the distribution of neutral gas, the overall stellar mass, or the number of GCs.

description: Self-control improvement programs are intended to serve many purposes, most notably improving self-control. Yet, interventions such as these often aim to reduce delinquency and problem behaviors. However, there is currently no summary statement available regarding whether or not these programs are effective in improving self-control and reducing delinquency and problem behaviors. The main objective of this review is to assess the available research evidence on the effect of self-control improvement programs on self-control and delinquency and problem behaviors. In addition to investigating the overall effect of early selfcontrol improvement programs, this review will examine, to the extent possible, the context in which these programs may be most successful. The studies included in this systematic review indicate that self-control improvement programs are an effective intervention for improving self-control and reducing delinquency and problem behaviors, and that the effect of these programs appears to be rather robust across various weighting procedures, and across context, outcome source, and based on both published and unpublished data.

description: We investigate certain $4$-dimensional analogues of the classical $3$-dimensional Dehn's lemma, giving examples where such analogues do or do not hold, in the smooth and topological categories. In particular, we show that an essential $2$-sphere $S$ in the boundary of a simply connected $4$-manifold $W$ such that $S$ is null-homotopic in $W$ need not extend to an embedding of a ball in $W$. However, if $W$ is simply connected (or more generally a $4$-manifold with abelian fundamental group) with boundary a homology sphere, then $S$ bounds a topologically embedded ball in $W$. Moreover, we give examples where such an $S$ does not bound any smoothly embedded ball in $W$. In a similar vein, we construct incompressible tori $T\subseteq \partial W$ where $W$ is a contractible $4$-manifold such that $T$ extends to a map of a solid torus in $W$, but not to any embedding of a solid torus in $W$. Moreover, we construct an incompressible torus $T$ in the boundary of a contractible $4$-manifold $W$ such that $T$ extends to a topological embedding of a solid torus in $W$ but no smooth embedding. As an application of our results about tori, we address a question posed by Gompf about extending certain families of diffeomorphisms of $3$-manifolds which he has recently used to construct infinite corks.

description: Recently, considerable attention has been focused on the brewing industry that are helping transform Ethiopia's business landscapes with alcoholic beverage industries having a lion's share in terms of investment and market. However, the country`s requirement of hops are met through import. Thus, the need to investigate some Ethiopian plants that could substitute hops in beer brewing. In this paper work bitter leaf (Vernonia amygdalina) was investigated using a reflux condenser extraction unit and appropriate solvent material to obtain the extract. Thereafter, the extract was characterized in order to determine its suitability for use in brewing by comparing it with those of standard commercial hops values. The optimization of process parameters for the bitter leaf extract was investigated using GFD. The three parameters and their ranges namely temperature (80-100oC), time (1-3hr), and particle size (0.25-1.0mm) were chosen. The individual parameters effect as well as effect of interactions between the process parameters on bitterness level and Iso alpha acid value was analyzed using various graphical representations. The physicochemical analysis of the bitter leaf showed that the sample extract had brewing properties or variables as follows: Iso-alpha acid (mg/l) ranged from 7.99-9.14, alpha acid (mg/l) of 9.51, total resin (%) of 19.72, hard resin (%) of 5.7, soft resin (%) of 14.02, protein content (%) of 27.73% and fat content (%) of 2.74. The Analytical Bitterness Unit (ABU) was found to be adequate and ranged from 16.55-17.1. The AAS results showed that the concentrations of metals of the samples investigated were Calcium (mg/100g) of 25.61±0.048, Magnesium (mg/100g) of 4.92±0.04, Iron (mg/100g) of 9.1±0.07and Zinc (mg/100g) of 2.27±0.052. Based on the comparison, it was observed that the brewing qualities of hops are present in bitter leaf to an appreciable level with variation in the protein and mineral contents. Consequently, the results obtained showed that bitter leaf presents an acceptably high level of their hop properties that is adequate for beer brewing. Key words: hop substitution, bitter leaf, optimization, bitterness level, Iso-alpha acid, alpha acid, resin.

Ground-based spectroscopic observations confirmed the planetary nature of the three transiting sub-Neptunes (HD 191939 b, c, and d) originally detected by TESS and were used to measure the masses for planets b and c with 3$σ$ precision. These previous observations also reported the discovery of an additional Saturn-mass planet (HD 191939 e) and evidence for a further, very long-period companion (HD 191939 f). Here, we report the discovery of a new non-transiting planet in the system and a refined mass determination of HD 191939 d. The new planet, HD 191939 g, has a minimum mass of 13.5$\pm$2.0 M$_\oplus$ and a period of about 280 d. This period places the planet within the conservative habitable zone of the host star, and near a 1:3 resonance with HD 191939 e. The compilation of 362 radial velocity measurements with a baseline of 677 days from four different high-resolution spectrographs also allowed us to refine the properties of the previously known planets, including a 4.6$σ$ mass determination for planet d, for which only a 2$σ$ upper limit had been set until now. We confirm the previously suspected low density of HD 191939 d, which makes it an attractive target for attempting atmospheric characterisation. Overall, the planetary system consists of three sub-Neptunes interior to a Saturn-mass and a Uranus-mass planet plus a high-mass long-period companion. This particular configuration has no counterpart in the literature and makes HD 191939 an exceptional multi-planet transiting system with an unusual planet demographic worthy of future observation.

description: Background: A congenital nephron deficit has been strongly implicated in the development of hypertension in adult life in humans and a variety of animal models. Using an ovine model of fetal uninephrectomy (uni-x), we have demonstrated that female uni-x sheep with intact ovaries develop hypertension by 2 years of age. Despite no overt exacerbation in hypertension or a further decline in glomerular filtration rate (GFR), these intact female uni-x sheep demonstrated greater reductions in renal blood flow (RBF) by 5 years of age. Aims: The aim of my studies was to examine the mechanisms underlying the perturbations in renal function in a cohort of 5-year old female uni-x sheep. Methods: Cardiovascular and renal responses to an acute saline load (2.5% body weight) during vehicle and furosemide (0.5 mg/kg bolus + 1 mg/kg/h, i.v) infusion, and to systemic nitric oxide (NO) inhibition (L-NAME, bolus 40mg/kg + 20mg/kg/h i.v.) were examined in conscious sham (n=7) and uni-x (n=7) sheep. Vascular reactivity was assessed in isolated renal arteries and in several other resistance arteries from sham (n=9) and uni-x (n=8) sheep. Results: Female uni-x sheep at 5 years of age exhibited an impaired ability to excrete an acute saline load, revealing not only reductions in the filtered load of sodium, but also alterations in tubular sodium reabsorption and reductions in the contribution of the renin angiotensin system (RAS) (Chapter 3). The effect of furosemide to increase RBF and GFR basally, as well as, abolish renal hemodynamic and PRA responses to a saline load observed in the sham animals, were all but absent in the uni-x sheep, suggesting that tubuloglomerular feedback (TGF) had been reset to a lower sensitivity. Furthermore, cyclooxygenase-2 (COX-2) expression was down-regulated within the renal cortex in uni-x sheep. Reduction in COX-2 derived prostaglandins, especially within the macula densa, could contribute to the reduced gain of the RAS, which may in turn, desensitize TGF in uni-x sheep (Chapter 4). Female uni-x sheep at 5 years of age demonstrated a reduced contribution of NO to the modulation of renal hemodynamics and sodium excretion. Moreover, the reduction in resting RBF and GFR in uni-x sheep was associated with renal vascular dysfunction, consisting of impaired basal NO production/bioavailability, endothelial dysfunction and enhanced smooth muscle responsiveness to vasoconstrictors and sympathetic nerve stimulation (Chapter 5). Conclusion: These findings highlight pivotal mechanisms underlying the perturbations in both cardiovascular and renal function, which may represent a vital link to the development and maintenance of hypertension in 5-year old female sheep born with a nephron deficit.

description: Understanding and quantifying polarization in social systems is important because of many reasons. It could for instance help to avoid segregation and conflicts in the society or to control polarized debates and predict their outcomes. In this paper we present a version of the $q$-voter model of opinion dynamics with two types of response to social influence: conformity (like in original $q$-voter model) and anticonformity. We put the model on a social network with the double-clique topology in order to check how the interplay between those responses impacts the opinion dynamics in a population divided into two antagonistic segments. The model is analyzed analytically, numerically and by means of Monte Carlo simulations. Our results show that the systems undergoes two bifurcations as the number of cross-links between cliques changes. Below the first critical point consensus in the entire system is possible. Thus two antagonistic cliques may share the same opinion only if they are loosely connected. Above that point the system ends up in a polarized state.

description: Wavefront-marking X-ray imaging techniques use e.g., sandpaper or a grating to generate intensity fluctuations, and analyze their distortion by the sample in order to retrieve attenuation, phase-contrast, and dark-field information. Phase contrast yields an improved visibility of soft-tissue specimens, while dark-field reveals small-angle scatter from sub-resolution structures. Both have found many biomedical and engineering applications. The previously developed Unified Modulated Pattern Analysis (UMPA) model extracts these modalities from wavefront-marking data. We here present a new UMPA implementation, capable of rapidly processing large datasets and featuring capabilities to greatly extend the field of view. We also discuss possible artifacts and additional new features.

description: NaOsO3 hosts a rare manifestation of a metal-insulator transition driven by magnetic correlations, placing the magnetic exchange interactions in a central role. We use resonant inelastic x-ray scattering to directly probe these magnetic exchange interactions. A dispersive and strongly gapped (58 meV) excitation is observed indicating appreciable spin-orbit coupling in this 5d3 system. The excitation is well described within a minimal model Hamiltonian with strong anisotropy and Heisenberg exchange (J1=J2=13.9 meV). The observed behavior places NaOsO3 on the boundary between localized and itinerant magnetism.

description: In this paper we provide predictions for the BH population that would be observable with planned JWST surveys at $5 \le z \le 15$. We base our study on the recently developed Cosmic Archaeology Tool (CAT), which allows us to model BH seeds formation and growth, while being consistent with the general population of AGNs and galaxies observed at $4 \le z \le 7$. We find that JWST planned surveys will provide a complementary view on active BHs at $z > 5$, with JADES-Medium/-Deep being capable of detecting the numerous BHs that populate the faint-end of the distribution, COSMOS-Web sampling a large enough area to detect the rarest brightest systems, and CEERS/PRIMER bridging the gap between these two regimes. The relatively small field of view of the above surveys preferentially selects BHs with masses $6 \leq {\rm Log} (M_{\rm BH}/M_\odot) < 8$ at $7 \le z < 10$, residing in relatively metal poor (${\rm Log} (Z/Z_\odot) \ge -2$) and massive ($8\leq {\rm Log} (M_*/M_\odot) < 10$) galaxies. At $z \ge 10$, only JADES-Deep will have the sensitivity to detect growing BHs with masses $4 \leq {\rm Log} (M_{\rm BH}/M_\odot) < 6$, hosted by more metal poor ($-3 \leq {\rm Log} (Z/Z_\odot) < -2$) and less massive ($6 \leq {\rm Log} (M_*/M_\odot) < 8$) galaxies. In our model, the latter population corresponds to heavy BH seeds formed by the direct collapse of super-massive stars in their earliest phases of mass growth. Detecting these systems would provide invaluable insights on the nature and early growth of the first BH seeds.
