description: We study the geometric Uhlmann phase of mixed states at finite temperature in a system of two coupled spin-$\frac 1 2$ particles driven by a magnetic field applied to one of the spins. In the parameter space of temperature and coupling, we show the emergence of two topological Uhlmann phase transitions when the magnetic field evolves around the equator, where a winding number can characterize each temperature range. For small couplings, the width of the temperature gap of the non-trivial phase is roughly the critical temperature $T_c$ of one-dimensional fermion systems with two-band Hamiltonians. The first phase transition in the low-temperature regime and small values of the coupling corresponds to the peak of the \textit{Schottky anomaly} of the heat capacity, typical of a two-level system in solid-state physics involving the ground and first excited states. The second phase transition occurs at temperatures very close to the second maximum of the heat capacity associated with a multilevel system. We also derive analytical expressions for the thermal Uhlmann phase for both subsystems, showing that they exhibit phase transitions. In the driven subsystem, for minimal $g$, a topological phase transition phase appears at $T_c$ again. However, for larger values of $g$, the transitions occur at lower temperature values, and they disappear when the coupling reaches a critical value $g_c$. The latter is not the case for the undriven subsystem, where at low temperatures, a single phase transition occurs at $g_c$. Nevertheless, as the temperature rises, we demonstrate the emergence of two phase transitions defining a coupling gap, where the phase is non-trivial and vanishes as the temperature reaches a critical value.

description: Background: HIV/AIDS affects many people globally and its burden was critical. According to the 2005 ANC - based HIV sentinel surveillance the prevalence of HIV at Federal police referral Hospital was 24.8%. The introduction of HAART significantly improved survival and quality of life for many individuals living with the disease. In Ethiopia studies also showed the contribution of HAART for patients. However, still there is lack of information on its outcome among the police community. Objective: The aim of this study is to assess survival of HIV/AIDS patients on HAART. Methods: Retrospective cohort study was conducted among HIV patients on HAART from Apr, 2005 to Mar, 2013 at Federal Police Referral Hospital, on a total sample size of 900, selected using systematic random sampling technique. Descriptive statistics to summarize characteristics of the study subjects, Kaplan - Meier survival function to estimate the probability of survival, log - rank test to compare survival in two or more groups and Cox proportional hazard model to determine factors associated with outcome was applied. Result: The median follow up period was 57 months (IQR, 23 - 89). The overall survival was 88% at 120 months follow up. About 8.3% of patients died and mortality was high (48%) in the first 6 month of follow up. Baseline ART regimen TDF+3TC+EFV (AHR=6.4,95%CI;1.6–25) and TDF+3TC+NVP (AHR=167.6,95% CI; 7.9 – 3525), Not working due to ill health (AHR =2.9,95% CI; 1.2 - 6.9), use of condom rarely (AHR =4.6, 95% CI; 1.6 – 12.7), Ambulatory (AHR =2.8, 95% CI; 1.2 – 6.9), Bed ridden (AHR =11.3,95% CI; 4.6 - 27), PCP (AHR = 3.6,95% CI; 1.4 – 9.2), WHO Treatment stage one (AHR=0.10,95%CI;0.03–0.4), Prophylaxis (AHR=2.6,95% CI:1.1–6.4), Current ART regimen TDF+3TC+EFV (AHR=0.2,95% CI; 0.05–0.76) and TDF+3TC+NVP (AHR =0.09,95% CI; 0.01–0.83), Fair drug adherence (AHR= 3.1,95% CI;1.6 – 6.2) and Recent CD4 cell count (AHR =0.99,95% CI; 0.994– 0.999) were the significant predictors for mortality after initiation of HAART among HIV patients in the adjusted Cox proportional hazard model. Conclusion: HAART improved survival. However, high mortality was observed in the first six month of follow up. It was associated with Baseline ART regiment, not working due to ill health , use of condom rarely, Ambulatory and bed ridden functional status, PCP after starting ART, current prophylaxis and fair adherence. Highlighting, the need for early and strong HIV testing and counseling to initiate treatment early before they progress to advanced stage.

description: In quantum Hall edge states and in other one-dimensional interacting systems, charge fractionalization can occur due to the fact that an injected charge pulse decomposes into eigenmodes propagating at different velocities. If the original charge pulse has some spatial width due to injection with a given source-drain voltage, a finite time is needed until the separation between the fractionalized pulses is larger than their width. In the formalism of non-equilibrium bosonization, the above physics is reflected in the separation of initially overlapping square pulses in the effective scattering phase. When expressing the single particle Green's function as a functional determinant of counting operators containing the scattering phase, the time evolution of charge fractionalization is mathematically described by functional determinants with overlapping pulses. We develop a framework for the evaluation of such determinants, describe the system's equilibration dynamics, and compare our theoretical results with recent experimental findings.

description: Context. The Extreme Ultraviolet Imager (EUI), onboard Solar Orbiter consists of three telescopes: the two High Resolution Imagers in EUV (HRIEUV) and in Lyman-α (HRILya), and the Full Sun Imager (FSI). Solar Orbiter/EUI started its Nominal Mission Phase on 2021 November 27. Aims. EUI images from the largest scales in the extended corona off limb, down to the smallest features at the base of the corona and chromosphere. EUI is therefore a key instrument for the connection science that is at the heart of the Solar Orbiter mission science goals. Methods. The highest resolution on the Sun is achieved when Solar Orbiter passes through the perihelion part of its orbit. On 2022 March 26, Solar Orbiter reached for the first time a distance to the Sun close to 0.3 au. No other coronal EUV imager has been this close to the Sun. Results. We review the EUI data sets obtained during the period 2022 March-April, when Solar Orbiter quickly moved from alignment with the Earth (2022 March 6), to perihelion (2022 March 26), to quadrature with the Earth (2022 March 29). We highlight the first observational results in these unique data sets and we report on the in-flight instrument performance. Conclusions. EUI has obtained the highest resolution images ever of the solar corona in the quiet Sun and polar coronal holes. Several active regions were imaged at unprecedented cadences and sequence durations. We identify in this paper a broad range of features that require deeper studies. Both FSI and HRIEUV operate at design specifications but HRILya suffered from performance issues near perihelion. We conclude emphasising the EUI open data policy and encouraging further detailed analysis of the events highlighted in this paper.

description: Background: The nursing/midwifery care standard practice is the levels of safe and competent practice but, its implementation status is poor & inconsistent, particularly in developing countries. Similarly, the baseline assessment in this study at Dil chora hospital was poor. Thus, it was critically important to improve the implementation of the Nursing/midwifery care standard practice in Dil chora Hospital. Objectives: To improve the implementation status of Nursing /midwifery Care Standards from 48.2% to 73% in Medical, surgical & Gynecology wards of Dil chora Hospital, by the end of May 2018. Method: A facility based pre- post interventional study was conducted from March to May 2018 in Dil chora Hospital, Dire Dawa, Ethiopia. The interventions include training of ward nurses; delegation of internal supportive supervision, strengthening nursing audit committee & facilitate to change the present nursing/midwifery process format with the new one. The same numbers of nurse/midwife participants (50 before & 50 after) and 80 medical cards (40 before & 40 after) were conducted by Simple random sampling method to compare the findings before & after interventions. The data were analyzed by using nursing/midwifery standard checklists. Result: Among the total 50 the same respondents (50 before & 50 after), mean age was 31.20 years (SD=5.338) and the implementation status of nursing/midwifery care standards was 25 (50.5%) in baseline 38 (76%) after-intervention. This change was statistically significant at (df =7, P ). Of the total of 80 medical card review documentation (before 40 & after 40) the implementation status of the standards in nursing/midwifery process & Medication administration record was 19 (47.5%) in baseline, 31 (77.5%) after-intervention. Conclusion and recommendation: The implementation status of the nursing /midwifery care standard practice is still below the expected criteria and it needs further intervention to increase its utilization. Knowledge, recognition & motivation are possible contributing factors for the improving of nursing/midwifery care standard practice those who are working at medical, surgical, & gynecology wards.

description: Using machine learning (ML) to recognize different phases of matter and to infer the entire phase diagram has proven to be an effective tool given a large dataset. In our previous proposals, we have successfully explored phase transitions for topological phases of matter at low dimensions either in a supervised or an unsupervised learning protocol with the assistance of quantum information related quantities. In this work, we adopt our previous ML procedures to study quantum phase transitions of magnetism systems such as the XY and XXZ spin chains by using spin-spin correlation functions as the input data. We find that our proposed approach not only maps out the phase diagrams with accurate phase boundaries, but also indicates some new features that have not observed before. In particular, we define so-called relevant correlation functions to some corresponding phases that can always distinguish between those and their neighbors. Based on the unsupervised learning protocol we proposed [Phys. Rev. B 104, 165108 (2021)], the reduced latent representations of the inputs combined with the clustering algorithm show the connectedness or disconnectedness between neighboring clusters (phases), just corresponding to the continuous or disrupt quantum phase transition, respectively.

description: In this paper, we propose to use deep policy networks which are trained with an advantage actor-critic method for statistically optimised dialogue systems. First, we show that, on summary state and action spaces, deep Reinforcement Learning (RL) outperforms Gaussian Processes methods. Summary state and action spaces lead to good performance but require pre-engineering effort, RL knowledge, and domain expertise. In order to remove the need to define such summary spaces, we show that deep RL can also be trained efficiently on the original state and action spaces. Dialogue systems based on partially observable Markov decision processes are known to require many dialogues to train, which makes them unappealing for practical deployment. We show that a deep RL method based on an actor-critic architecture can exploit a small amount of data very efficiently. Indeed, with only a few hundred dialogues collected with a handcrafted policy, the actor-critic deep learner is considerably bootstrapped from a combination of supervised and batch RL. In addition, convergence to an optimal policy is significantly sped up compared to other deep RL methods initialized on the data with batch RL. All experiments are performed on a restaurant domain derived from the Dialogue State Tracking Challenge 2 (DSTC2) dataset.

description: Die zeitlichen Verläufe des von der Drehmomentmeßwelle angezeigten Drehmomentes, der Drehzahl und der Klemmenspannung sowie des Ständerstromes werden für unterschiedliche Hochläufe berechnet und mit Messungen verglichen. Hierbei liegt ein Schwerpunkt auf der Hochlaufgefährdung durch parasitäre synchrone Drehmomente, ein anderer auf der Berechnung von Torsionsschwingungen, insbesondere in Resonanz. Zum Hochlaufverhalten werden zusätzlich speziell für den Einlauf in synchrone Drehmomentsättel Rechnungen mit einer praktischen Näherung bei sinusförmiger Klemmenspannung durchgeführt. Es ergibt sich eine höhere Hochlaufgefährdung bei einem Keilriemenantrieb gegenüber der direkten Kupplung. Mit Drehstromsteller zeigt sich, daß bei verzerrter Klemmenspannung und Strom fast ausschließlich die Grundschwingungen zur Entwicklung von Drehmoment und Leistungen beitragen. Eine Dimensionierung des Antriebes ist daher nicht nach dem Effektivwert, sondern nach den Grundschwingungen von Klemmenspannung und Strom vorzunehmen. Beim Antrieb mit einer zusätzlichen Schwungmasse über Keilriemen kann eine bislang unbekannte "quasisynchrone Schleichdrehzahl" rechnerisch und experimentell nachgewiesen werden.
description: The time-functions of the torque indicated by a torque-measuring-shaft, the speed and the terminal voltage as well as the stator-currents are calculated for different running up tests and compared to measurements. Herein one focal point lies on the danger of a running up inhibited by parasitic synchronous torques, another one is given by the calculation of torsional vibrations, in particular in resonance. Concerning the running up behaviour additional calculations using a practical approximation at sinusoidal voltage are carried out especially for the incoming in synchronous torques. As a result a higher endangering of the running up is found for the V-belt drive compared to a drive with a direct coupling. With a three phase ac power controller it appears that almost exclusively the fundamental harmonics of the distorted terminal voltage and current contribute to the generation of torque and power. Therefore a dimensioning of the drive cannot be done according to the rms-values but must be done according to the fundamental harmonics of terminal voltage and current. With the drive having an additional fly-wheel driven via V-belt a so far unknown "quasi-synchronous" creeping speed can be proved numerically and experimentally.

description: The abundance of carbon relative to oxygen (C/O) is a promising probe of star formation history in the early universe, as the ratio changes with time due to production of these elements by different nucleosynthesis pathways. We present a measurement of $\log{\mathrm{(C/O)}} = -1.01\pm0.12$ (stat) $\pm0.15$ (sys) in a $z=6.23$ galaxy observed as part of the GLASS-JWST Early Release Science Program. Notably, we achieve good precision thanks to the detection of the rest-frame ultraviolet O III], C III], and C IV emission lines delivered by JWST/NIRSpec. The C/O abundance is $\sim$0.8 dex lower than the solar value and is consistent with the expected yield from core-collapse supernovae, indicating that longer-lived intermediate mass stars have not fully contributed to carbon enrichment. This in turn implies rapid buildup of a young stellar population with age $\lesssim100$ Myr in a galaxy seen $\sim$900 million years after the Big Bang. Our chemical abundance analysis is consistent with spectral energy distribution modeling of JWST/NIRCam photometric data, which indicates a current stellar mass $\log\,\mathrm{M}_* / \mathrm{M_{sun}} = 8.4^{+0.4}_{-0.2}$ and specific star formation rate sSFR $\simeq 20$ Gyr$^{-1}$. These results showcase the value of chemical abundances and C/O in particular to study the earliest stages of galaxy assembly.

description: We present a new methodology for simulating mid-infrared emission from polycyclic aromatic hydrocarbons (PAHs) in galaxy evolution simulations. To do this, we combine theoretical models of PAH emission features as they respond to varying interstellar radiation fields, grain size distributions, and ionization states with a new on-the-fly model for dust evolution in hydrodynamic galaxy simulations. We apply these models to 3 idealized arepo galaxy evolution simulations within the smuggle physics framework. We use these simulations to develop numerical experiments investigating the buildup of PAH masses and luminosities in galaxies in idealized analogs of the Milky Way, a dwarf galaxy, and starburst disk. Our main results follow. Galaxies with high specific star formation rates have increased feedback energy per unit mass, and are able to efficiently shatter dust grains, driving up the fraction of ultra small grains. At the same time, in our model large radiation fields per unit gas density convert aliphatic grains into aromatics. The fraction of dust grains in the form of PAHs (q_PAH) can be understood as a consequence of these processes, and in our model PAHs form primarily from interstellar processing (shattering) of larger grains rather than from the growth of smaller grains. We find that the hardness of the radiation field plays a larger role than variations in the grain size distribution in setting the total integrated PAH luminosities, though cosmological simulations are necessary to fully investigate the complex interplay of processes that drive PAH band luminosities in galaxies. Finally, we highlight feature PAH strength variations, cautioning against the usage of emission templates with constant feature strength ratios.

description: Background: Achalasia is a rare esophageal motility disorder of uncertain etiology. While past studies have indicated that autoimmune conditions and viral infections may be associated with development of achalasia, these associations are yet to be examined in large, population-based studies. Methods: A matched case-control study was performed using administrative claim data from the IBM MarketScan Commercial Claims and Encounters Database between 2000 and 2019. A history of selected autoimmune conditions and viral infections was assessed using past medical claims. Multivariable conditional logistic regression was used to account for the matched nature of the study design and further control for confounding by demographic and clinical characteristics when reporting adjusted odds ratios (aORs). Key Results: Among 6769 cases and 27,076 controls, presence of any of the autoimmune conditions studied was associated with increased odds of achalasia (aOR = 1.26, 95% CI: 1.11, 1.42). Scleroderma or systemic sclerosis (aOR = 8.13, 95% CI: 3.34, 19.80) and Addison's disease (aOR = 3.83, 95% CI: 1.83, 8.04) had the strongest associations with achalasia. Presence of any of the viral infections studied was also associated with an increased risk of achalasia (aOR = 1.58, 95% CI: 1.23, 2.01). Varicella zoster virus (aOR = 3.84, 95% CI: 1.94, 7.62) and human papillomavirus (aOR = 1.77, 95% CI: 1.15, 2.73) both had strong relationships with achalasia. Conclusions and Inferences: These findings suggest that achalasia may have autoimmune and viral components contributing to its etiology. Future mechanistic studies could target specific diseases and agents highlighted by this research.

description: Background: Children are "agents of change" in pacing the behaviour and practice of their family and community at large. Hygiene and sanitation in schools is important, as it allows children to learn about hygiene at a receptive age, as well as having immediate and long term health benefits. Poor hygiene behaviour remains high risk behaviour increasingly responsible for high water and sanitation related diseases among primary school going children. Many outbreaks of gastrointestinal infections have been associated with primary schools Objectives: assessing the factors influencing hygiene behaviour among school children. Methods: A school children based descriptive cross sectional study was conducted. Five Primary schools was recruited from the list of primary schools with second cycle in the Woreda Education Office and a total of 528 School children were selected randomly selected from the list of every school based on the proportion to the size of grade six to eight of each school. Fifty percent of students" house hold was assessed for availability of hygiene enabling facilities. All questionnaires and records were checked by the data collectors and supervisors before leaving the data collection area. Statistical analysis was done using SPSS Version 17.0 after the data has been entered using Epi-Info version 3.5.3. Logistic regression employed to identify factors influencing hygiene behaviour via crude and adjusted odds ratio. Result: the study found that knowledge and awareness on water handling, and hand washing was significantly associated to hygiene behaviour. The likelihood that the child"s knowledge on water handling issues and hand washing matters was 2.24 times (AOR, 2.24; 95%CI 1.54, 3.26) and 1.7 times (AOR, 1.70; 95%CI 1.12, 2.57) likely to have positive hygiene behaviour compared to those was not knowledgeable, respectively. Predictably, school children who had proper awareness on water handling matters 2 (AOR, 2.0; 95%CI 1.37, 2.90), hand washing practice 2.36(AOR, 2.36; 95%CI 1.62, 3.45) times more likely to have positive hygiene behaviour compare to those school children not aware. Being a member of hygiene and sanitation club, parent"s health package status, have ever trained on hygiene and sanitation and have ever visit model school had observed a significance difference in hygiene behaviour. The peer pressure measured by "what you think children are washing their hands" was observed a difference in handwashing behaviour. This was statistically significant with diseases avoidance P <0.05. Conclusion: we conclude that this study has shown that knowledge, awareness, ever training, being a member, visit model school, and parent"s health package are factors to influence hygiene behaviour.

description: Ziel dieser Arbeit ist es die Grundlagen für die Strukturierung, für die Konfiguration sowie für den Betrieb eines EDV-basierten Logistikinformationssystems zu entwickeln, das Produktionsnetzwerke, bestehend aus kleinen und mittelständischen Unternehmen, bei der Adaption von Supply Chain Management-Prinzipien anforderungsgerecht unterstützt. Der innerhalb dieser Arbeit verfolgte Ansatz stützt sich dabei auf die kombinierte Analyse und Verwendung der Nutzen- und Entwicklungspotentiale von intelligenter Transpondertechnik sowie des Internets. Transponder werden zum einen im Hinblick auf ihre Eignung als materialbegleitende, dezentrale und eindeutig identifizierbare Datenbanken untersucht und zum anderen in Bezug auf ihre Verwendbarkeit als technologische Plattform für die Implementierung von Mehrwertdiensten geprüft. Dabei gilt es insbesondere, das für den Einsatz von Transpondertechnik so wichtige Kosten-Nutzen-Verhältnis erheblich zu verbessern.Die im Rahmen dieser Dissertation vorgenommenen Betrachtungen münden in der Erstellung eines Grundkonzeptes sowie der damit verknüpften Ableitung von praxisorientierten Einführungs-, Konfigurations- und Betriebsregeln für ein transponder- und internetbasiertes Logistikinformationssystem, welches sowohl den Bedürfnissen als auch den Beschränkungen von im Verbund agierenden kleinen und mittelständischen Unternehmen entspricht. Die Ergebnisse dieser Arbeit repräsentieren somit einen Leitfaden für interessierte Unternehmen, auf dessen Basis Einsatzpotentiale identifiziert, Aufwände abgeschätzt sowie Lastenhefte entworfen werden können.

description: Η εν λόγω εργασία θα αναπτύξει το φαινόμενο ενδοοικογενειακής βίας και της παιδικής κακοποίησης, στις διάφορες πτυχές της, σωματική, ψυχολογική, σεξουαλική βία κ. λπ. Η ενδοοικογενειακή βία και παιδική κακοποίηση, υπήρχε από την αρχαιότητα έως και σήμερα. Στις περιπτώσεις βίας, ο πιο συνήθες και ευάλωτος πληθυσμός προς έκθεση στη βία είναι τα παιδιά, καθώς είναι δύσκολο να υπερασπιστούν τον εαυτό τους και τα δικαιώματά τους. Τα σωστά θεμέλια και οι πόροι με τους οποίους θα εφοδιαστεί το παιδί από τους γονείς του, θα το επηρεάζουν σε όλη του την ζωή μετέπειτα. Έτσι, εάν δεν υπάρχει ποιότητα στη φροντίδα του παιδιού και η σχέση του γονέα με το παιδί είναι διαταραγμένη από τη παιδική του ηλικία, τότε αυτό επηρεάζει την συναισθηματική ψυχοσύνθεσή του, την ανασφάλειά και την ανησυχία του παιδιού. Τα παιδιά είναι πιθανό να έρθουν σε άμεση ή έμμεση έκθεση με την βία και αυτό έχει αρνητικές συνέπειες για την ψυχολογική και κοινωνική τους ζωή έως και την ενήλικη ζωή τους. Η παρούσα εργασία λοιπόν, επιδιώκει να αναλύσει και να αναπτύξει τις μορφές βίας της παιδικής κακομεταχείρησης, τη θέση του θύτη και του θύματος, τα δικαιώματα του παιδιού και ποιός τα υπερασπίζεται όταν αυτά καταπατούνται, τρόπους πρόληψης και αντιμετώπισης της κατάστασης, την παρέμβαση και την υποστήριξη του κοινωνικού λειτουργού, άλλων αρμόδιων φορέων και τέλος τις διεθνείς έρευνες που έχουν γίνει έως τώρα για την παιδική κακομεταχείριση
description: The current paper will develop the phenomenon of domestic violence and child abuse, in its various aspects, physical, psychological, sexual violence, etc. Domestic violence and child abuse have existed since antiquity. In cases of violence, children are the most common and vulnerable population to exposure to violence, as it is difficult to defend themselves and their rights. The right foundations and resources that will be provided to the child by his parents, will affect him throughout his life later. Thus, if there is no quality in child care and the parent-child relationship is disrupted from childhood, then this affects the emotional psychosynthesis, insecurity and stress of the child. Children are likely to be directly or indirectly exposed to violence and this has negative consequences for their psychological and social life until adulthood. This paper attempts to analyze and develop the forms of violence of child abuse, the position of the perpetrator and the victim, the rights of the child and who defends them when they are violated, ways to prevent and deal with the situation, intervention and support of the social worker, others bodies and the end of international child abuse investigations to date.

description: We perform a detailed study of an effective field theory which includes the Standard Model particle content extended by a pair of Weyl fermionic SU(2)-doublets with opposite hypercharges. A discrete symmetry guarantees that a linear combination of the doublet components is stable and can act as a candidate particle for Dark Matter. The dark sector fermions interact with the Higgs and gauge bosons through renormalizable $d=4$ operators, and non-renormalizable $d=5$ operators that appear after integrating out extra degrees of freedom above the TeV scale. We study collider, cosmological and astrophysical probes for this effective theory of Dark Matter. We find that a WIMP with a mass nearby to the electroweak scale, and thus observable at LHC, is consistent with collider and astrophysical data only when fairly large magnetic dipole moment transition operators with the gauge bosons exist, together with moderate Yukawa interactions.

description: We present the renormalisation group running of the bosonic operators of the Standard Model effective field theory by the Lepton Number Violating operators (LNVs) at 1-loop order up to $\mathcal{O}(v^4/Λ^4)$, with $v \sim 246$ GeV as the electroweak scale and $Λ$ as the SMEFT cut-off. Using these relations with the positivity bounds on Wilson coefficients of $ϕ^4 D^4$ class, we derive sign-constraints on the Wilson coefficients of LNV operators for models where $ϕ^4 D^4$ operators do not appear at tree-level. We inspect these constraints for the LNV Wilson coefficients generated from matching the Type-I and III seesaw models to SMEFT up to dimension seven at tree-level. We also exhibit the unique bounds induced by the T-parameter on LNVs.

Inversion of Zeeman polarization for solar magnetic field diagnostics
Creators: name: Derouich, M.
Publisher: name: arXiv
Year: 2016
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The topic of magnetic field diagnostics with the Zeeman effect is currently vividly discussed. There are some testable inversion codes available to the spectropolarimetry community and their application allowed for a better understanding of the magnetism of the solar atmosphere. In this context, we propose an inversion technique associated with a new numerical code. The inversion procedure is promising and particularly successful for interpreting the Stokes profiles in quick and sufficiently precise way. In our inversion, we fit a part of each Stokes profile around a target wavelength, and then determine the magnetic field as a function of the wavelength which is equivalent to get the magnetic field as a function of the height of line formation. To test the performance of the new numerical code, we employed "hare and hound" approach by comparing an exact solution (called input) with the solution obtained by the code (called output). The precision of the code is also checked by comparing our results to the ones obtained with the HAO MERLIN code. The inversion code has been applied to synthetic Stokes profiles of the Na D$_{1}$ line available in the literature. We investigated the limitations in recovering the input field in case of noisy data. As an application, we applied our inversion code to the polarization profiles of the Fe {\sc i} $λ$ 6302.5 Å observed at IRSOL in Locarno.

description: Methanolic extract and fractions, ethylacetate (EtF) and butanol (BuF) of leaves of African mistletoe (Tapinanthus bangwensis, Engl. & K. Krause) were evaluated for their hepatoprotective potential using CCl4-induced hepatotoxicity in Wistar albino rats. The activities of the marker enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and bilirubin were highest in rats treated with CCl4 alone. Oral administration at a fixed dose of 400 mg/kg body weight (BW) of the extract and fractions of T. bangwensis for seven days significantly (p ≤ 0.05) decreased the activity of marker enzymes and bilirubin. Total protein concentration increased significantly (p ≤ 0.05). These extracts also decreased the concentration of thiobarbituric acid reactive substances (TBARS) which indicated a reduction in lipid peroxidation. Histopathological examination of hepatocytes of rats administered methanolic extract (MeE) and fractions (EtF and BuF) showed normal architecture whereas rats treated with CCl4 alone was characterized by necrosis of the liver. Generally, among the three extracts, the BuF and EtF showed more hepatoprotective effect. The crude methanolic extract did not show any mortality up to a dose of 2000 g/kg BW. These findings suggest that T. bangwensis possesses strong antioxidant properties and hepatoprotective potentials against CCl4–induced hepatotoxicity in rats.

description: The basic beer-brewing industrial practices have barely changed over time. While well proven and stable, they have been refractory to substantial innovation. Technologies harnessing hydrodynamic cavitation have emerged since the 1990s' in different technical fields including the processing of liquid foods, bringing in advantages such as acceleration of extraction processes, disinfection and energy efficiency. Nevertheless, so far beer-brewing processes were not investigated. The impacts of controlled hydrodynamic cavitation, managed by means of a dedicated unit on a real microbrewery scale (230 L), on the beer-brewing processes is the subject of this paper. The physico-chemical features of the obtained products, analyzed by means of professional instruments, were compared with both literature data and data from the outcomes of a traditional equipment. Traditional processes such as dry milling of malts and wort boiling becoming entirely unnecessary, dramatic reduction of saccharification temperature, acceleration and increase of starch extraction efficiency, relevant energy saving, while retaining safety, reliability, scalability, virtually universal application to any brewing recipe, beer quality, were the most relevant experimental results. The impacts of these findings are potentially far reaching, beer being the worldwide most widely consumed alcoholic beverage, therefore highly relevant to health, environment, the economy and even to local identities.

description: The focus of this doctoral thesis was on the synthesis of members and analogues of a broader family of marine oxylipins. A modular, first and enantioselective protecting-group free total synthesis of Ecklonialactones A and B is described. The chiral information is introduced at the very beginning of the synthesis either by means of (-)-menthol as a chiral auxiliary or by the chiral ligands in a Rhodiumcatalyzed 1,4-addition. All further reactions proceed under substrate-control with very high diastereoselectivities. The 14-membered macrolactone is obtained by a ringclosing alkyne metathesis (RCAM) using newly available, highly active Molybdenumalkylidyne complexes under very mild reaction conditions. Additionally, the results of NMR-investigations on Ecklonialactone A are presented. The epoxide of this natural product was opened regioselectively to give Eiseniachloride A. More surprisingly, a rearrangement has also lead to a chlorinated, cyclopropane-containing derivative of an unnamed natural product. Finally, a non-natural derivative of Hybridalactone ("Desethyl-hybridalactone") has been synthesized, and further work towards the synthesis of natural Hybridalactone is also presented. In the second part of this thesis, the results of cytotoxicity assays using cancer cell lines and synthetic natural products, especially the Ipomoeassins, are described. Simple structure-activity-relationships were found among this group of natural products.
On the three-dimensional Euler equations with a free boundary subject to surface tension
Creators: name: Schweizer, Ben
Publisher: name: Elsevier
Year: 2005
Subjects: subject: 510

description: We study an incompressible ideal fluid with a free surface that is subject to surface tension; it is not assumed that the fluid is irrotational. We derive a priori estimates for smooth solutions and prove a short-time existence result. The bounds are obtained by combining estimates of energy type with estimates of vorticity type and rely on a careful study of the regularity properties of the pressure function. An adequate artificial coordinate system is used instead of the standard Lagrangian coordinates. Under an assumption on the vorticity, a solution to the Euler equations is obtained as a vanishing viscosity limit of solutions to appropriate Navier–Stokes systems.
