Kurzfassung
Der hohe Bedarf an einer dynamischen und kundenindividuellen Produktion rückt die Flexibilität von Produktionssystemen zunehmend in den Fokus. Industrieroboter leisten heute einen entscheidenden Beitrag zur Befriedigung dieses Bedarfes. Obwohl sie in der Handhabung bereits Stand der Technik sind, finden sie in der mechanischen Fertigung, nach wie vor nur selten Anwendung. Das Trochoidfräsen bietet ein Potenzial zur Steigerung der Zerspanleistung Pc [1, 2]. Diese hochdynamische Frässtrategie erzeugt deutlich geringere Schnittkräfte Fc als konventionelles Fräsen und steigert gleichzeitig das Zeitspanvolumen Qw [2, 3, 4].

Incorporating Surface Convection into a 3D Babcock–Leighton Solar Dynamo Model
Authors: Hazra Gopal , Miesch Mark S. 
Published: September 2018

Abstract
The convective flows observed on the photosphere (e.g., supergranulation, granulation) play a key role in the Babcock–Leighton (BL) process to generate large-scale polar fields from sunspot fields. In most surface flux transport (SFT) and BL dynamo models, the dispersal and migration of surface fields are modeled as an effective turbulent diffusion. Recent SFT models have incorporated explicit, realistic convective flows in order to improve the fidelity of convective transport but, to our knowledge, this has not yet been implemented in previous BL models. We present the first kinematic 3D Flux-Transport/BL model to explicitly incorporate realistic convective flows based on solar observations. Though we describe a means to generalize these flows to 3D, we find that the kinematic small-scale dynamo action they produce disrupts the operation of the cyclic dynamo. The cyclic solution is found by limiting the convective flow to act only on the vertical radial component of the magnetic field. The results obtained are generally in good agreement with the observed surface flux evolution and with non-convective models that have a turbulent diffusivity of the order of 3 × 1012 cm2 s−1 (300 km2 s−1). However, we find that the use of a turbulent diffusivity underestimates the dynamo efficiency, producing weaker mean fields and a shorter cycle than in the convective models. Also, the convective models exhibit bands of mixed polarity in the polar regions that have no counterpart in solar observations, and the poleward migration speed of poloidal flux is determined mainly by the meridional flow and the vertical diffusion.
Unraveling the Complex Structure of AGN-driven Outflows. III. The Outflow Size–Luminosity Relation
Authors: Kang Daeun , Woo Jong-Hak 
Published: September 2018

Abstract
Energetic gas outflows driven by active galactic nuclei (AGNs) are considered as one of the mechanisms by which supermassive black holes affect their host galaxies. To probe the impact of AGN-driven outflows, it is essential to quantify the size of the region under the influence of such outflows. In the third of a series of papers, we present the spatially resolved kinematics of ionized gas for three additional Type 2 AGNs based on Gemini Multi-Object Spectrograph (GMOS) integral field spectroscopy. Along with the six AGNs presented in our previous works and the 14 AGNs with available GMOS-integral field unit data, we construct a sample of 23 luminous Type 2 AGNs at z < 0.2, and kinematically measure the size of ionized gas outflows by tracing the radial decrease of the velocity dispersion of the [O iii] λ5007 emission line. The kinematically measured outflow size ranges from 0.60 to ∼7.45 kpc, depending on AGN luminosity. We find that the size of the photoionized region is larger than the kinematically measured outflow size, while the flux-weighted photoionization size is significantly smaller. Thus, using photoionization size as a proxy for outflow size leads to overestimation or underestimation, and introduces large uncertainties of the mass outflow rate and the energy output rate. We report an outflow size–luminosity relation with a slope of 0.28 ± 0.03, which is shallower than the slope of the correlation between the photoionization size and luminosity.

Published: September 2018

Abstract
Evolutionary studies that compare galaxy structure as a function of redshift are complicated by the fact that any particular galaxy’s appearance depends in part on the rest-frame wavelength of the observation. This leads to the necessity for a “morphological k-correction” between different passbands, especially when comparing the rest-frame optical or infrared (IR) to the ultraviolet (UV). This is of particular concern for high-redshift studies that are conducted in the rest-frame UV. We investigate the effects of this “bandpass shifting” out of the UV by quantifying nearby galaxy structure via concentration, asymmetry, and clumpiness (CAS) parameters. For this study we combine panchromatic data from the UV through the near-IR with Galaxy Evolution Explorer (GALEX) data of 2073 nearby galaxies in the “near-UV” (NUV; ∼230 nm) and 1127 in the “far-UV” (FUV; ∼150 nm), providing the largest study of this kind in the mid- to far-UV. We find a relationship between the CAS parameters and observed rest-frame wavelength that make galaxies appear more late-type at shorter wavelengths, particularly in the UV. The effect is strongest for E/S0 galaxies in the far-UV, which have concentrations and asymmetries that more closely resemble those of spiral and peculiar/merging galaxies in the optical. This may be explained by extended disks containing recent star formation. Here, we also release the CAS values of the galaxies imaged in GALEX NUV and FUV for use in comparisons with deep Hubble Space Telescope imaging and the James Webb Space Telescope in the future.
Turbulent Transport by Diffusive Stratified Shear Flows: From Local to Global Models. III. A Closure Model
Authors: Kulenthirarajah Logithan , Garaud Pascale 
Published: September 2018

Abstract
Being able to account for the missing mixing in stellar radiative zones is a key step toward a better understanding of stellar evolution. Zahn argued that thermally diffusive shear-induced turbulence might be responsible for some of this mixing. In Part I and Part II of this series of papers, we showed that Zahn’s mixing model applies when the properties of the turbulence are local. But we also discovered limitations of the model when this locality condition fails, in particular near the edge of a turbulent region. In this paper, we propose a second-order closure model for the transport of momentum and chemical species by shear-induced turbulence in strongly stratified, thermally diffusive environments (the so-called low Péclet number (LPN) limit), which builds upon the work of Garaud & Ogilvie. Comparison against direct numerical simulations (DNSs) shows that the model is able to predict the vertical profiles of the mean flow and of the stress tensor (including the momentum transport) in diffusive shear flows, often with a reasonably good precision, and at least within a factor of order unity in the worst case scenario. The model is sufficiently simple to be implemented in stellar evolution codes, and all the model constants have been calibrated against DNSs. While significant limitations to its use remain (e.g., it can only be used in the slowly rotating LPN limit), we argue that it is more reliable than most of the astrophysical prescriptions that are used in stellar evolution models today.
Studies of Turbulence Dissipation in the Taurus Molecular Cloud with Core Velocity Dispersion

Published: September 2018

Abstract
Turbulence dissipation is an important process affecting the energy balance in molecular clouds, the birth place of stars. Previously, the rate of turbulence dissipation is often estimated with semi-analytic formulae from simulation. Recently, we developed a data analysis technique called core velocity dispersion, which, for the first time, provides direct measurements of the turbulence dissipation rate in Taurus, a star-forming cloud. The thus measured dissipation rate of

is similar to those from dimensional analysis, and is also consistent with the previous energy injection rate based on molecular outflows and bubbles.
The Formation of Extremely Diffuse Galaxy Cores by Merging Supermassive Black Holes

Published: September 2018

Abstract
Given its velocity dispersion, the early-type galaxy NGC 1600 has an unusually massive (M
• = 1.7 × 1010
M
⊙) central supermassive black hole (SMBH) surrounded by a large core (r
b = 0.7 kpc) with a tangentially biased stellar distribution. We present high-resolution equal-mass merger simulations including SMBHs to study the formation of such systems. The structural parameters of the progenitor ellipticals were chosen to produce merger remnants resembling NGC 1600. We test initial stellar density slopes of ρ ∝ r
−1 and ρ ∝ r
−3/2 and vary the initial SMBH masses from 8.5 × 108 to 8.5 × 109
M
⊙. With increasing SMBH mass, the merger remnants show a systematic decrease in central surface brightness, an increasing core size, and an increasingly tangentially biased central velocity anisotropy. Two-dimensional kinematic maps reveal decoupled, rotating core regions for the most massive SMBHs. The stellar cores form rapidly as the SMBHs become bound, while the velocity anisotropy develops more slowly after the SMBH binaries become hard. The simulated merger remnants follow distinct relations between the core radius and the sphere of influence, and the SMBH mass, similar to observed systems. We find a systematic change in the relations as a function of the progenitor density slope and present a simple scouring model reproducing this behavior. Finally, we find the best agreement with NGC 1600 using SMBH masses totaling the observed value of M
• = 1.7 × 1010
M
⊙. In general, density slopes of ρ ∝ r
−3/2 for the progenitor galaxies are strongly favored for the equal-mass merger scenario.

Published: September 2018

Abstract
We present an updated catalog of 4680 northern eclipsing binaries (EBs) with Algol-type light-curve (LC) morphology (i.e., with well-defined beginnings and ends of primary and secondary eclipses), using data from the Catalina Sky Surveys. Our work includes revised period determinations, phenomenological parameters of the LCs, and system morphology classifications based on machine-learning techniques. While most of the new periods are in excellent agreement with those provided in the original Catalina catalogs, improved values are now available for ∼10% of the stars. A total of 3456 EBs were classified as detached and 449 were classified as semi-detached, while 145 could not be classified unambiguously into either subtype. The majority of the SD systems seem to be comprised of short-period Algols. By applying color criteria, we searched for K- and M-type dwarfs in these data, and present a subsample of 609 EB candidates for further investigation. We report 119 EBs (2.5% of the total sample) that show maximum quadrature light variations over long timescales, with periods bracketing the range 4.5–18 years and a fractional luminosity variance range of 0.04–0.13. We discuss possible causes for this, making use of models of variable starspot activity in our interpretation of the results.
Bronchial Allergen Challenge of Patients with Atopic Asthma Triggers an Alarmin (IL-33, TSLP, and IL-25) Response in the Airways Epithelium and Submucosa

Published: September 2018

Abstract
The alarmin cytokines IL-25, IL-33, and thymic stromal lymphopoietin (TSLP) play a critical role in asthma pathogenesis by inducing mucosal Th2-type cytokine production. Although environmental exposure to aeroallergens has been proposed as an alarmin trigger in asthma, there has been no systematic parallel study of the effects of allergen exposure on the expression of these cytokines in the airways of human asthmatics. Using single and sequential double immunohistochemistry, we evaluated the numbers and phenotypes of IL-25–, IL-33–, and TSLP-immunoreactive cells in sections of bronchial biopsies from mild atopic asthmatics (n = 16) before and 24 h after allergen inhalational challenge. Allergen challenge highly increased expression of baseline immunoreactivity for IL-25, IL-33, and TSLP, both in the bronchial epithelium and submucosa (p &lt; 0.001), to a degree that correlated with the extent of the late phase of airway obstruction. Aside from epithelial cells, the principal source of immunoreactivity for all three alarmins, TSLP, and IL-33 immunoreactivity colocalized principally with endothelial cells and mast cells, neutrophils, and fibroblasts, whereas IL-25 immunoreactivity colocalized principally with eosinophils as well as endothelial cells, mast cells, and fibroblasts. The data implicate that allergen challenge directly increases airway alarmin expression in atopic asthmatics to a degree correlating with increase late-phase airway obstruction, affirming these molecules as potential molecular targets for the inhibition of allergen-induced airway inflammation and obstruction.

Published: September 2018

Background: Research consistently demonstrates the importance of effective team work for improving the quality of health care. We conducted a baseline measure of primary health care (PHC) team effectiveness and overall PHC performance at a primary care facility.Aim: To improve PHC team effectiveness and ultimately the quality and user experience of primary care at a community health centre (CHC).Setting: Du Noon CHC in the southern and western substructure of the Cape Town Metro district services (MDHS).Methods: A cross-sectional study using a combination of the Nominal Group Technique (NGT) consensus method and the South African Primary Care Assessment Tool (ZA PCAT) to assess PHC team effectiveness and PHC organisation and performance.Results: The ZA PCAT was administered to 110 CHC users (patients) and 12 providers (doctors and clinical nurse practitioners). Data from 20 PHC team members showed they perceived their team as well functioning (70% agreement on a 7-item PHC team assessment tool incorporated into the ZA PCAT). The NGT method achieved participant (20) consensus on communication and leadership as the main challenges to effective team functioning and on ideas to overcome the challenges. The ZA PCAT user data showed 18.2% of users rated first contact access as acceptable to good; 47.3% of users rated ongoing care as acceptable to good. Provider data showed that 33% of providers rated first contact access as acceptable to good; 25% of providers rated ongoing care as acceptable to good. First contact access received the lowest acceptable to good score (18.2%) and comprehensiveness (services available) the highest score (88.2%) from users. For the providers, the lowest acceptable to good score was for ongoing care (25%) and the highest acceptable to good score was for primary health care team availability (100%). The ZA PCAT total primary scores were good (above 60%) for both users and providers but moderately higher for the providers.Conclusion: Knowledge of how teams perceive their effectiveness can motivate them to generate ideas for improving performance. There were discrepancies between providers’ assessment of team functioning using the ZA PCAT measure and the NGT method results. The ZA PCAT also showed differences between providers’ and users’ perceptions of PHC performance – consistent with the findings of the multi-CHC Western Cape ZA PCAT study. These findings should encourage and support CHC and district level staff in their efforts to improve the quality and user experience of primary care, as well as PHC team performance.

Une coexistence créative entre théologie et sciences des religions: quel travail à déployer, des deux côtés?
Authors: Gisel Pierre 
Published: September 2018

Ce texte sanctionne la double existence de la théologie d’une part, des sciences des religions de l’autre. Cette dualité est non dépassable, pour des raisons de fond relatives aux « intérêts » humains et sociaux en cause à chaque fois. Mais cette dualité peut être féconde pour chacune. Moyennant bien sûr qu’on les repense, l’une comme l’autre. Ce à quoi s’exerce la présente contribution. Qui précise au final en quoi la théologie, ainsi repensée, peut être riche d’enseignements pour les sciences des des religions, et en quoi les sciences des religions sont pleines de richesses humaines instructives pour le travail et la réflexion théologiques, tout en étant en même temps un lieu de défis et une occasion de déplacements qui ne peuvent qu’en relancer la réflexion.
