description: In this letter we report observations of magnetic switchback (SB) features near 1 au using data from the \emph{Wind} spacecraft. These features appear to be strikingly similar to the ones observed by the Parker Solar Probe mission (PSP) closer to the Sun: namely, one-sided spikes (or enhancements) in the solar-wind bulk speed $V$ that correlate/anti-correlate with the spikes seen in the radial-field component $B_R$. In the solar-wind streams that we analyzed, these specific SB features near 1 au are associated with large-amplitude Alfvénic oscillations that propagate outward from the sun along a local background (prevalent) magnetic field $\bf{B}_0$ that is nearly radial. We also show that, when $\bf{B}_0$ is nearly perpendicular to the radial direction, the large amplitude Alfvénic oscillations display variations in $V$ that are two-sided (i.e., $V$ alternately increases and decreases depending on the vector $Δ\bf{B}=\bf{B} - \bf{B}_0$). As a consequence, SBs may not appear always as one-sided spikes in $V$, especially at larger heliocentric distances where the local background field statistically departs from the radial direction. We suggest that SBs can be well described by large-amplitude Alfvénic fluctuations if the field rotation is computed with respect to a well-determined local background field that, in some cases, may deviate from the large-scale Parker field.

description: The detection of a branched alkyl molecule in the high-mass star forming protocluster Sgr B2(N) permitted by the advent of ALMA revealed a new dimension of interstellar chemistry. Astrochemical simulations subsequently predicted that beyond a certain degree of molecular complexity, branched molecules could even dominate over their straight-chain isomers. More generally, we aim at probing further the presence in the ISM of complex organic molecules with the capacity to exhibit both a normal and iso form, via the attachment of a functional group to either a primary or secondary carbon atom. We used the imaging spectral line survey survey ReMoCA performed with ALMA and the results of a recent spectroscopic study of propanol to search for the iso and normal isomers of this molecule in the hot molecular core Sgr B2(N2). We expanded the network of the astrochemical model MAGICKAL to explore the formation routes of propanol. We report the first interstellar detection of iso-propanol toward a position of Sgr B2(N2) that shows narrow linewidths. We also report the first secure detection of normal-propanol in a hot core. i-Propanol is found to be nearly as abundant as n-propanol, with an abundance ratio of 0.6 similar to the ratio of 0.4 that we obtained previously for i- and n-propyl cyanide in Sgr B2(N2). The results are in good agreement with the outcomes of our astrochemical models, which indicate that OH-radical addition to propylene in dust-grain ice mantles, driven by water photodissociation, can produce appropriate quantities of n- and i-propanol. The n-to-i ratio in Sgr B2(N2) may be a direct inheritance of the branching ratio of this reaction process. The detection of n- and i-propanol and their ratio indicate that the modest preference toward the normal form of propyl cyanide determined previously may be a more general feature among similarly sized interstellar molecules.

description: Many bacteria are motile by means of one or more rotating rigid helical flagella, making them the only known organism to use rotation as a means of propulsion. The rotation is supplied by the bacterial flagellar motor, a particularly powerful rotary molecular machine. At the base of each flagellum is the hook, a soft helical polymer that acts as a universal joint, coupling rotation of the rigid membrane-spanning rotor to rotation of the rigid extra-cellular flagellum. In multi-flagellated bacterial species, where thrust is provided by a hydrodynamically coordinated bundle of flagella, the flexibility of the hook is particularly crucial, as many of the flagella within the bundle rotate significantly off-axis from their motor. But, consequently, the thrust produced by a single rotating flagellum applies a significant bending moment to the hook. So, the hook needs to simultaneously provide the compliance necessary for off-axis bundle formation and the rigidity necessary to withstand the large hydrodynamical forces of swimming. To elucidate how the hook can fulfill this double functionality, measurements of the mechanical behavior of individual hooks under dynamical conditions are needed. Here, via new high-resolution measurements and a novel analysis of hook fluctuations during in vivo motor rotation in bead assays, we resolve the elastic response of single hooks under increasing torsional stress, revealing a clear dynamic increase in their bending stiffness. Accordingly, the persistence length of the hook increases by more than one order of magnitude with applied torque. Such strain-stiffening allows the system to be flexible when needed yet reduce deformation under high loads, allowing cellular motility at high speed.

description: We present a novel approach for the detection of events in systems of ordinary differential equations. The new method combines the unique features of Taylor integrators with state-of-the-art polynomial root finding techniques to yield a novel algorithm ensuring strong event detection guarantees at a modest computational overhead. Detailed tests and benchmarks focused on problems in astrodynamics and celestial mechanics (such as collisional N-body systems, spacecraft dynamics around irregular bodies accounting for eclipses, computation of Poincare' sections, etc.) show how our approach is superior in both performance and detection accuracy to strategies commonly employed in modern numerical integration works. The new algorithm is available in our open source Taylor integration package heyoka.

description: We perform a manifestly covariant quantization of a Weyl invariant, i.e., a locally scale invariant, scalar-tensor gravity in the extended de Donder gauge condition (or harmonic gauge condition) for general coordinate invariance and a new scalar gauge for Weyl invariance within the framework of BRST formalism. It is shown that choral symmetry, which is a Poincar${\rm{\acute{e}}}$-like $\IOSp(8|8)$ supersymmetry in case of Einstein gravity, is extended to a Poincar${\rm{\acute{e}}}$-like $\IOSp(10|10)$ supersymmetry. We point out that there is a gravitational conformal symmetry in quantum gravity and account for how conventional conformal symmetry in a flat Minkowski space-time is related to the gravitational conformal symmetry. Moreover, we examine the mechanism of spontaneous symmetry breakdown of the choral symmetry, and show that the gravitational conformal symmetry is spontaneously broken to the Poincaré symmetry and the corresponding massless Nambu-Goldstone bosons are the graviton and the dilaton. We also prove the unitarity of the physical S-matrix on the basis of the BRST quartet mechanism.

title: EE-Methan als Treibstoff
Creators: name: Mahler, Judith-Maria
Year: 2017

description: Die weltweite Bevölkerungsrate nimmt kontinuierlich zu und mit ihr aus heutiger Sicht ebenso die Rate an CO2-Emissionen. Da der Verkehrs- und Transportsektor als einer der Hauptverursacher von CO2-Emissionen gilt, ist es zwingend notwendig, hier mögliche klimaneutrale Antriebsarten zum Einsatz zu bringen und herkömmliche Antriebsarten somit auf ein Minimum zu reduzieren. Erdgasfahrzeuge in Kombination mit EE-Methan als Kraftstoff stellen hierfür eine optimale CO2-neutrale Alternative dar. Um die Bevölkerung für Themen wie den Klimawandel, dessen Folgen und die potentiellen Gegenmaßnahmen zu sensibilisieren, stellen Massenmedien die bestmöglichste Art dar. Denn durch Massenmedien, die als Tageszeitungen und Zeitschriften in dieser Arbeit beschrieben werden, können innerhalb kürzester Zeit breite Bevölkerungsschichten erreicht werden. Mit Hilfe der Informationen, die die Rezipienten bzw. Leser durch die Berichterstattung erhalten, können sich diese in weiterer Folge Gedanken über aktuelle Ereignisse machen. In unterschiedlichen Studien wurde dabei eine positive Korrelation zwischen der Intensität der Berichterstattung zu einem bestimmten Thema und einer daraus resultierenden Aufmerksamkeit der Bevölkerung beobachtet. In dieser Arbeit wird daher die Thematisierung von EE-Methan im Mobilitätssektor innerhalb der deutschen und österreichischen Massen- bzw. Printmedien analysiert. Wie bereits erwähnt, kann EE-Methan als klimaneutraler Treibstoff für Erdgasfahrzeuge einen großen Beitrag zur CO2-Reduktion leisten. EE-Methan wird dabei mit Hilfe der PtG Technologie gewonnen, die sich jedoch in den meisten Ländern noch im Forschungs- und Entwicklungsstadium befindet. Die erste Versuchsanlage auf industrieller Basis wurde 2013 von der Automobilfirma Audi in Kooperation mit ETOGAS errichtet. Seitdem ist der Kraftstoff EE-Methan bzw. E-Gas, wie es Audi nennt, an einigen deutschen Erdgastankstellen erhältlich.

description: We have performed phase-resolved spectral analysis of the accreting pulsar 1A~0535+262 based on observations of Insight-HXMT during the 2020 Type-II outburst of the source. We focus on the two-dimensional dependence of the cyclotron resonance scattering features (CRSFs) along the outburst time and at different phases. The fundamental CRSF line (f-CRSF) shows different time- and phase-dependent behaviors. At higher luminosity, the phase profile of the f-CRSF energy changes from a single peak to double peaks, with the transition occurring at MJD 59185. On the contrary, the first harmonic CRSF (1-st CRSF) at $\sim$ 100 keV is only detected within a narrow phase range (0.8$-$1.0) accompanied by a shallow f-CRSF line. Based on these results, we speculate that when the source enters the supercritical regime, the higher accretion column can significantly enhance the harmonic line at a narrow phase through an "anti-pencil" beam at a higher energy band. At the same time, it will also affect the behavior of the fundamental line.

description: Increased knowledge about wave attenuation processes in sea ice, and hence atmosphere-wave-ice-ocean energy transfer, is necessary to improve sea ice dynamics models used for climate modeling and offshore applications. The aim of this study is to generate such much needed data by investigating colliding ice floes dynamics in a large-scale experiment and directly measuring and quantifying the turbulent kinetic energy (TKE). The field work was carried out at Van Mijen Fjord on Svalbard, where a 3x4 m ice floe was sawed out in the fast ice. Wave motion was simulated by pulling the ice floe back and forth in an oscillatory manner in a 4x6 m pool, using two electrical winches. Ice floe motion was measured with a range meter and accelerometers, and the water turbulence was measured acoustically with an acoustic Doppler current profiler and optically with a remotely operated vehicle and bubbles as tracers. TKE frequency spectra were found to contain an inertial subrange where energy was cascading at a rate proportional to the -5/3 power law. The TKE dissipation rate was found to decrease exponentially with depth. The total TKE dissipation rate was estimated by assuming that turbulence was induced over an area corresponding to the surface of the floe. The results suggest that approximately 37% and 8% of the input power from the winches was dissipated in turbulence and absorbed in the collisions, respectively, which experimentally confirms that energy dissipation by induced turbulent water motion is an important mechanism for colliding ice floe fields.

description: Several studies have examined the impact of COVID-19 emergence on people’s mental health, investigating the relationship between risk perception and psychological well-being, (especially for people in quarantine) and between risk perception and the adoption of healthy behaviors. Few studies have focused explicitly on the elderly, a population identified as particularly vulnerable to SARS-CoV-2 infection and its consequences. The objective of the present research was to study the relationship between the elderly experience of the pandemic and the perceived risk of infection with three variables: emotional regulation, perceived acute stress, and quality of life. The results showed that Direct experience of the pandemic was related to lower stress levels and higher emotional regulation. While Indirect experience and the perceived risk of COVID-19 contagion were related to a higher level of acute stress, poorer emotional regulation, and a significant reduction in quality of life. The pandemic situation and, in particular, the fear of contagion seems to have left an important mark on older people, who manifest high levels of Risk as Feeling together with high levels of acute stress. Therefore, high risk perception may be an important peritraumatic factor.

title: Empirische Analyse zu Firmenwerten und deren Wertminderungen - Vergleich der Technologieunternehmen im TecDAX und im Nikkei 225
Creators: name: Bronisova, Jana
Year: 2017

description: Der Firmenwert gehört zu den wichtigsten Posten der konsolidierten Abschlüsse vieler Unternehmen. Seine zunehmende Relevanz ist insbesondere in der Tatsache begründet, dass der Firmenwert enorme Größen annehmen kann und dadurch einen erheblichen Anteil am Gesamtvermögen der Unternehmen ausmacht. Insbesondere in den letzten Jahren ist ein steigender Trend der Buchwerte der Firmenwerte erkennbar. Im Rahmen dieser Masterarbeit werden zwei möglichen Faktoren, die die Ursache für diese progressive Entwicklung der Firmenwerte sein können, vorgeschlagen. Es sind das die Methode der Folgebewertung der Firmenwerte und die zunehmende Globalisierung. Der Einfluss dieser Faktoren wird anhand der Daten, die bei der Analyse der TecDAX- und der Nikkei-225-Unternehmen in den Geschäftsjahren 2005 bis 2015 erhoben wurden, geprüft. Analysiert wurden nur Unternehmen der Technologiebranche. Die Technologieunternehmen sind überwiegend junge und stark wachsende Unternehmen, die relativ hohe Buchwerte der Firmenwerte in ihren Konzernabschlüssen ausweisen. Außer einer empirischen Analyse werden im Zuge dieser Masterarbeit auch die Grundlagen der Bilanzierung der Firmenwerte in den Konzernabschlüssen der kapitalmarktorientieren Unternehmen in der EU und in Japan erläutert.

description: Introdução: A celulite da região orbitária é uma patologia que pode associar-se a complicações potencialmente graves.

Objectivo: Caracterização dos casos de celulite orbitária e periorbitária internados num Serviço de Pediatria.

Métodos: Revisão casuística dos casos de celulite orbitária ou periorbitária internados no Serviço de Pediatria nos anos de 1995 a 2005.

Resultados: Identificaram-se 71 casos – 65 celulites periorbitárias (92%) e seis celulites orbitárias (8%). A maioria ocorreu em crianças até os cinco anos de idade (73%) e no período do Outono/Inverno (68%). A infecção respiratória alta foi a patologia associada em 37% dos casos de celulite periorbitária e a sinusopatia em 100% dos casos de celulite orbitária. Solicitou-se tomografia computorizada em 31% dos casos. A associação de sinusopatia à celulite orbitária esteve presente em seis casos, coincidente com o grupo que apresentava sintomas e sinais clínicos que fizessem suspeitar de uma situação de maior gravidade. A maioria das crianças foi tratada com monoterapia antibiótica (83%), sendo a mais frequente o cefuroxime (39%), seguido de amoxicilina-ácido clavulânico (37%). Todos os casos evoluiram sem complicações.

Conclusão: A sinusopatia foi a patologia associada em todos os casos de celulite orbitária. A tomografia computorizada tem importância na investigação diagnóstica e apresenta indicações específicas para a sua solicitação.

description: A series of reduced-order numerical simulations on a specific bluff body type (v-gutters) in a subsonic duct flow is done to assess the unsteady wake dynamics. Two of the v-gutter's geometrical parameters are varied: the v-gutter's base angle ($θ$) and the size of a slit ($ξ$) at the leading-edge of the v-gutter. Turbulent flow kinematics and pressure field are analyzed to evaluate the unsteadiness at a freestream Mach number of $M_\infty = 0.25$ and a freestream Reynolds number based on bluff body's transverse length (L) of $Re_L=0.1 \times 10^6$. Five v-gutter angles are considered ($θ$, $^\circ = π/6, π/4, π/3, 5π/12, π/2$) and three slit sizes ($ξ$, mm =0,0.25,0.5) are considered only for a particular $θ= [π/6]$. In general, high fluctuations in velocity and pressure are seen for the bluffest body in consideration ($θ= π/2$) with higher drag ($c_d$) and total pressure loss ($Δp_0$). On the other hand, the presence of a slit on a streamlined body ($θ= π/6$) tends to efficiently stabilize the wake and thus, producing almost a periodic shedding structure with lower $c_d$ and $Δp_0$. For $θ= [π/6]$, broadened spectra in vortex shedding is seen with a peak at $[fL/u_\infty] \sim 0.08$. For $θ\geq [π/4]$, a dominant discrete shedding frequency is seen with a gradual spectral decay. Similarly, the effects of $ξ$ on the $θ= [π/6]$ case produce a discrete shedding frequency instead of a broadened one, as told before. The shedding frequency increases to a maximum of $[fL/u_\infty] \sim 0.26$ for the maximum slit size of $ξ= 0.5$. More insights on the shedding vortices, momentum deficit in the wake, varying energy contents in the flow field, and the dominant spatiotemporal structures are also provided.

description: We present a barrier method for treating frictional contact on interfaces embedded in finite elements. The barrier treatment has several attractive features, including: (i) it does not introduce any additional degrees of freedom or iterative steps, (ii) it is free of inter-penetration, (iii) it avoids an ill-conditioned matrix system, and (iv) it allows one to control the solution accuracy directly. We derive the contact pressure from a smooth barrier energy function that is designed to satisfy the non-penetration constraint. Likewise, we make use of a smoothed friction law in which the stick-slip transition is described by a continuous function of the slip displacement. We discretize the formulation using the extended finite element method to embed interfaces inside elements, and devise an averaged surface integration scheme that effectively provides stable solutions without traction oscillations. Subsequently, we develop a way to tailor the parameters of the barrier method to embedded interfaces, such that the method can be used without parameter tuning. We verify and investigate the proposed method through numerical examples with varied levels of complexity. The numerical results demonstrate that the proposed method is remarkably robust for challenging frictional contact problems, while requiring low cost comparable to that of the penalty method.

description: Introdução: A bronquiolite é uma infecção respiratória baixa muito frequente nas crianças de baixa idade e também uma causa frequente de hospitalização no Inverno. Uma significativa parte das atitudes terapêuticas classicamente praticadas, não têm suficiente suporte científico.

Objectivos: Analisar a orientação das crianças com bronquiolite, hospitalizadas na Unidade de Internamento de Curta Duração (UICD) de um Serviço de Urgência (SU).

Material e métodos: Foram analisados retrospectivamente os processos clínicos de todas as crianças internadas em UICD, em Janeiro e Fevereiro de 2005, com o diagnostico de bronquiolite e avaliados os pedidos de exames complementares, as atitudes terapêuticas e a evolução.

Resultados: No período do estudo foram internadas nesta Unidade 38 crianças com o diagnóstico de bronquiolite. A mediana da idade foi de três meses e a duração média do internamento foi de 40 horas. Durante o internamento necessitaram de um suplemento de O2 84% das crianças. As nebulizações com salbutamol foram prescritas em 36.8% dos casos e nenhuma das crianças foi tratada com brometo de ipratrópio ou adrenalina. A prednisolona foi prescrita em 13% das crianças.Foi solicitada radiografia de tórax em 45% dos casos.Foram prescritos antibióticos em quatro casos e cinesiterapia a uma criança. Regressaram ao domicílio 68% das crianças, tendo as restantes sido internadas na Enfermaria de Medicina.

Conclusões: Tendo em conta os dados da literatura, julgamos que os resultados desta avaliação revelam um padrão de orientação que, no geral, é positivo mas, sem prejuízo da qualidade dos cuidados, pensamos ser possível reduzir os pedidos de radiografias de tórax e a prescrição de salbutamol. Programas de avaliação e de melhoria da qualidade de prescrição, devem ser implementados e mantidos nas Instituições.

description: Objectivo: Construir curvas de percentis do peso de nascimento para a idade gestacional, na população de recém-nascidos de um Hospital de Apoio Perinatal Diferenciado na área da Grande Lisboa.

Metodologia: Análise dos registos do peso de nascimento e idade gestacional dos recém-nascidos do hospital desde Janeiro de 2000 a Dezembro de 2004. A idade gestacional foi calculada pelo primeiro dia da última menstruação, ou baseada na ecografia, se esta foi realizada até às 22 semanas. O peso de nascimento foi avaliado em balança electrónica nos primeiros minutos de vida.

Resultados: no período referido, houve 25834 nascimentos. Destes, 966 foram excluídos: 136 nados mortos, 305 por idade gestacional desconhecida e 525 de gravidez gemelar. Obtivemos um total de 24868 nados vivos, com idade gestacional compreendida entre as 22 e 43 semanas. A variação da média do peso em meninas e meninos, de acordo com a idade gestacional foi a seguinte: 1021g/1167 g às 28 semanas, 1896g/1963 g às 32 semanas, 3241 g/3360 g às 39 semanas. Com os dados obtidos, construímos curvas de percentis (p5, p10,p25, p50, p75, p90 e p95) para cada idade gestacional.

Comentários: A realização deste estudo e a construção de tabelas de percentis adequadas à população do hospital, permite-nos uma definição mais correcta dos grupos de risco, do seu prognóstico e como consequência a elaboração de estratégias de prevenção adequadas. A avaliação do crescimento intra-uterino dos recém-nascidos em Portugal deveria utilizar curvas obtidas na sua população. Contudo, é importante incluir outras variáveis como o comprimento, o perímetro cefálico, a patologia materna, o peso e altura dos pais e desse modo definir de forma correcta o crescimento intra-uterino adequado, para cada idade gestacional, nesta população.

description: We interpret the 1.3mm VLBI observations made by the Event Horizon Telescope of the black hole in M87. It is proposed that, instead of being a torus of accreting gas, the observed annular ring is a rotating, magnetically-dominated ergomagnetosphere that can transmit electromagnetic angular momentum and energy outward to the disc through a combination of large scale magnetic torque and small scale instabilities. It is further proposed that energy can be extracted by magnetic flux threading the ergosphere through the efficient emission of long wavelength electromagnetic disturbances onto negative energy orbits, when the invariant $B^2-E^2$ becomes negative. In this way, the spinning black hole and its ergosphere not only power the jets but also the ejection disc so as to drive away most of the gas supplied near the Bondi radius. This outflow takes the form of a MHD wind, extending over many decades of radius, with a unidirectional magnetic field, that is collimated by the infalling gas across a magnetopause. This wind, in turn, collimates the relativistic jets and the emission observed from the jet sheath may be associated with a return current. A model for the global flow of mass, angular momentum, energy and current, on scales from the horizon to the Bondi radius, is presented and discussed.

description: A infecção neonatal pelo vírus Herpes simplex é rara mas cursa com morbilidade e mortalidade elevadas. Nas últimas décadas a prevalência de herpes genital e neonatal tem aumentado. No recém-nascido descrevem-se três formas de apresentação clínica: sistémica ou disseminada, do sistema nervoso central ou dos tecidos mucocutâneos, sendo esta a mais frequente. Apresentam-se três casos de herpes neonatal mucocutâneo em que num deles a apresentação cutânea orientou o diagnóstico para a forma clínica de doença disseminada. Todas as mães estavam assintomáticas e desconheciam infecção herpética genital prévia. Nos recém-nascidos o diagnóstico foi confirmado por polimerase chain reaction. Todas as crianças foram medicadas com aciclovir, registando-se recorrências em duas delas.

description: A intoxicação digitálica intencional é um evento raro em idade pediátrica. Tal como nos adultos, doses tóxicas de digoxina podem acarretar arritmias graves e fatais. Apresenta-se o caso de uma adolescente de 14 anos que ingeriu voluntariamente 4,75 mg de digoxina (0,1 mg/kg) e 1,2 g de furosemida (24 mg/kg). Duas horas após a ingestão inicia bradicardia sinusal sustentada sintomática com necessidade de colocação de pacemaker endocavitário provisório. Neste caso, a intoxicação por digoxina e furosemida relegaram para segundo plano o uso de anticorpos Fab anti-digoxina, dada a sua indisponibilidade em tempo útil e a possibilidade de ocorrência de hipocaliemia grave. Assim, apesar de controverso, o pacemaker foi utilizado com sucesso.

description: We report the results of X-ray (CXO) and radio (ATCA) observations of the pulsar wind nebula (PWN) powered by the young pulsar PSR J1016--5857, which we dub "the Goose" PWN. In both bands the images reveal a tail-like PWN morphology which can be attributed to pulsar's motion. By comparing archival and new CXO observations, we measure the pulsar's proper motion $μ=28.8\pm7.3$ mas/yr, yielding a projected pulsar velocity $v \approx 440\pm110$ km/s (at d=3.2 kpc); its direction is consistent with the PWN shape. Radio emission from the PWN is polarized, with the magnetic field oriented along the pulsar tail. The radio tail connects to a larger radio structure (not seen in X-rays) which we interpret as a relic PWN (also known as a plerion). The spectral analysis of the CXO data shows that the PWN spectrum softens from $Γ=1.7$ to $Γ\approx2.3-2.5$ with increasing distance from the pulsar. The softening can be attributed to rapid synchrotron burn-off, which would explain the lack of X-ray emission from the older relic PWN. In addition to non-thermal PWN emission, we detected thermal emission from a hot plasma which we attribute to the host SNR. The radio PWN morphology and the proper motion of the pulsar suggest that the reverse shock passed through the pulsar's vicinity and pushed the PWN to one side.

description: Os cuidados à pele da criança são uma área com que diariamente lidamos, não só nas nossas crianças e doentes, como também pelo marketing agressivo que enfrentamos através da informação médica, dos meios audiovisuais e pela sua presença em todos os locais de venda. Pela sua importância é um mercado em permanente expansão que envolve gastos enormes pelas empresas que os produzem. Estes factos fazem com que a oferta, por ser grande, leve a uma confusão tanto maior quanto menor a informação e os conhecimentos sobre o assunto, parecendo actual a sua revisão.
