Kurzfassung
Das induktive Anlassen bekommt aufgrund der kurzen Prozesszeiten und der dadurch wirtschaftlicheren Produktionsmöglichkeiten vor allem bei Stabmaterial eine immer größere Bedeutung. Allerdings kommt es durch die schnelle Erwärmung und die kurzen Haltedauern zu einer veränderten Ausscheidungskinetik und dadurch zu einem unterschiedlichen Härte-Anlass-Verhalten gegenüber einer konventionellen Wärmebehandlung. Des Weiteren tritt bei der induktiven Erwärmung das Problem des sogenannten “Skin-Effekts“ auf, welcher bei schlechter Prozesssteuerung zu einer überhöhten Randtemperatur, verglichen mit der im Kern, führt. Diese prozessbedingten Charakteristika erschweren das Verständnis der Auswirkung des Prozesses auf die Mikrostruktur des untersuchten Vergütungsstahles. Diese Arbeit möchte daher mithilfe eines kombinierten Ansatzes aus Experimenten an einer Laborinduktionsanlage und Simulationen mithilfe der Finite-Elemente-Methode (FEM) die Optimierung bzw. individuelle Feineinstellung von induktiven Anlassvorgängen für Stab-Geometrien aus dem betrachteten Werkstoff aufzeigen. Dazu wurde mittels FEM-Simulationen die zeitliche Entwicklung des Temperaturfeldes im Werkstück berechnet und diese mit experimentellen Resultaten zu Mikrostruktur, Härte und Zähigkeit in Verbindung gebracht.

Abstract
We present the complete optical transmission spectrum of the hot Jupiter WASP-4b from 440 to 940 nm at R ∼ 400–1500 obtained with the Gemini Multi-Object Spectrometers (GMOS); this is the first result from a comparative exoplanetology survey program of close-in gas giants conducted with GMOS. WASP-4b has an equilibrium temperature of 1700 K and is favorable to study in transmission due to its large scale height (370 km). We derive the transmission spectrum of WASP-4b using four transits observed with the MOS technique. We demonstrate repeatable results across multiple epochs with GMOS, and derive a combined transmission spectrum at a precision about twice above photon noise, which is roughly equal to one atmospheric scale height. The transmission spectrum is well fitted with a uniform opacity as a function of wavelength. The uniform opacity and absence of a Rayleigh slope from molecular hydrogen suggest that the atmosphere is dominated by clouds with condensate grain sizes of ∼1 μm. This result is consistent with previous observations of hot Jupiters since clouds have been seen in planets with similar equilibrium temperatures to WASP-4b. We describe a custom pipeline that we have written to reduce GMOS time-series data of exoplanet transits, and present a thorough analysis of the dominant noise sources in GMOS, which primarily consist of wavelength- and time-dependent displacements of the spectra on the detector, mainly due to a lack of atmospheric dispersion correction.
Search for Hydrogenated C60 (Fulleranes) in Circumstellar Envelopes

Abstract
The recent detection of fullerene (C60) in space and the positive assignment of five diffuse interstellar bands to

reinforce the notion that fullerene-related compounds can be efficiently formed in circumstellar envelopes and be present in significant quantities in the interstellar medium. Experimental studies have shown that C60 can be readily hydrogenated, raising the possibility that hydrogenated fullerenes (or fulleranes, C60H
m
, m = 1–60) may be abundant in space. In this paper, we present theoretical studies of the vibrational modes of isomers of C60H
m
. Our results show that the four mid-infrared bands from the C60 skeletal vibrations remain prominent in slightly hydrogenated C60, but their strengths diminish in different degrees with increasing hydrogenation. It is therefore possible that the observed infrared bands assigned to C60 could be due to a mixture of fullerenes and fulleranes. This provides a potential explanation for the observed scatter of the C60 band ratios. Our calculations suggest that a feature around 15 μm due to the breathing mode of heavily hydrogenated C60 may be detectable astronomically. A preliminary search for this feature in 35 C60 sources is reported.
The Effect of a Twisted Magnetic Field on the Phase Mixing of the Kink Magnetohydrodynamic Waves in Coronal Loops
Authors: Ebrahimi Zanyar , Karami Kayoomars , Soler Roberto 
Published: August 2017

Abstract
There is observational evidence for the existence of a twisted magnetic field in the solar corona. This inspires us to investigate the effect of a twisted magnetic field on the evolution of magnetohydrodynamic (MHD) kink waves in coronal loops. With this aim, we solve the incompressible linearized MHD equations in a magnetically twisted nonuniform coronal flux tube in the limit of long wavelengths. Our results show that a twisted magnetic field can enhance or diminish the rate of phase mixing of the Alfvén continuum modes and the decay rate of the global kink oscillation depending on the twist model and the sign of the longitudinal (k

z
) and azimuthal (m) wavenumbers. Also, our results confirm that in the presence of a twisted magnetic field, when the sign of one of the two wavenumbers m and k

z
is changed, the symmetry with respect to the propagation direction is broken. Even a small amount of twist can have an important impact on the process of energy cascading to small scales.

Abstract
Long-wavelength spectral distortions in the cosmic microwave background arising from the 21 cm transition in neutral hydrogen are a key probe of the Cosmic Dawn and the Epoch of Reionization. These features may reveal the nature of the first stars and ultra-faint galaxies that transformed the spin temperature and ionization state of the primordial gas. SARAS 2 is a spectral radiometer purposely designed for the precision measurement of these monopole or all-sky global 21 cm spectral distortions. We use 63 hr nighttime observations of the radio background in the frequency band 110–200 MHz, with the radiometer deployed at the Timbaktu Collective in Southern India, to derive likelihoods for plausible redshifted 21 cm signals predicted by theoretical models. First light with SARAS 2 disfavors the class of models that feature weak X-ray heating (with

) and rapid reionization (with peak

mK per unit redshift interval).

There is growing interest in mining polymetallic nodules from the abyssal Clarion-Clipperton Zone (CCZ) in the tropical Pacific Ocean. Despite having been the focus of environmental studies for decades, the benthic megafauna of the CCZ remain poorly known. To predict and manage the environmental impacts of mining in the CCZ, baseline knowledge of the megafauna is essential. The ABYSSLINE Project has conducted benthic biological baseline surveys in the UK Seabed Resources Ltd polymetallic-nodule exploration contract area (UK-1). Prior to ABYSSLINE research cruises in 2013 and 2015, no biological studies had been done in this area of the eastern CCZ.
Using a Remotely Operated Vehicle and Autonomous Underwater Vehicle (as well as several other pieces of equipment), the megafauna within the UK Seabed Resources Ltd exploration contract area (UK-1) and at a site ~250 km east of the UK-1 area were surveyed, allowing us to make the first estimates of megafaunal morphospecies richness from the imagery collected. Here, we present an atlas of the abyssal annelid, arthropod, bryozoan, chordate, ctenophore and molluscan megafauna observed and collected during the ABYSSLINE cruises to the UK-1 polymetallic-nodule exploration contract area in the CCZ. There appear to be at least 55 distinct morphospecies (8 Annelida, 12 Arthropoda, 4 Bryozoa, 22 Chordata, 5 Ctenophora, and 4 Mollusca) identified mostly by morphology but also using molecular barcoding for a limited number of animals that were collected. This atlas will aid the synthesis of megafaunal presence/absence data collected by contractors, scientists and other stakeholders undertaking work in the CCZ, ultimately helping to decipher the biogeography of the megafauna in this threatened habitat.

Published: August 2017

A major aim of gene therapy is the efficient and specific delivery of therapeutic gene into the desired target tissues. Development of reliable vectors is a major challenge in gene therapy. The aim of this study is to develop calcium phosphate nanoparticles as novel non-viral vectors for the gene delivery system. Calcium phosphate nanoparticles were prepared by water-in-oil microemulsion method with a water to surfactant molar ratio, Wo [Formula: see text] 2–10. This paper studies the design and synthesis of ultra-low size, highly monodispersed DNA doped calcium phosphate nanoparticles of size around 100[Formula: see text]nm in diameter. The structure of DNA-calcium phosphate nanocomplex observed by TEM was displayed as a shell-like structure. This study used pEGFP as a reporter gene. The encapsulating efficiency to encapsulate DNA inside the nanoparticles was greater than 80%. In the MTT test, both calcium phosphate nanoparticles and DNA-calcium phosphate nanocomplex have no negative effect for 293T cells. By gel electrophoresis of free and entrapped pEGFP DNA, the DNA encapsulated inside the nanoparticles was protected from the external DNaseI environment. In vitro transfection studies in 293T cell-line, the DNA-calcium phosphate nanocomplex could be used safely to transfer the encapsulated DNA into the 293T cells and expression green fluorescent protein. The characteristic of DNA-calcium phosphate nanocomplex to deliver DNA belongs to slow release. The property of DNA-calcium phosphate nanocomplex was fit in the requirement of non-viral vectors for the gene delivery system.

Published: August 2017

Background:The treatment of symptomatic partial rotator cuff tear has presented substantial challenge to orthopaedic surgeons as it can vary from conservative to surgical repair. Researches have established the influence of platelet rich plasma in healing damaged tissue. Currently very few data are available regarding the evidence of clinical and radiological outcome of partial rotator cuff tear treated with ultrasound guided platelet rich plasma injection in English literature.Materials and Methods:20 patients with symptomatic partial rotator cuff tears were treated with ultrasound guided platelet rich plasma injection. Before and after the injection of platelet rich plasma scoring was done with visual analogue score, Constant shoulder score, and UCLA shoulder score at 8 weeks and third month. A review ultrasound was performed 8 weeks after platelet rich plasma injection to assess the rotator cuff status.Results:Our study showed statistically significant improvements in 17 patients in VAS pain score, constant shoulder score and UCLA shoulder score. No significant changes in ROM were noted when matched to the contra-lateral side (P< 0.001) at the 3 month follow-up. The study also showed good healing on radiological evaluation with ultrasonogram 8 weeks after platelet rich plasma injection.Conclusion:Ultrasound guided platelet rich plasma injection for partial rotator cuff tears is an effective procedure that leads to significant decrease in pain, improvement in shoulder functions, much cost-effective and less problematic compared to a surgical treatment.
Development and Validation of a Stability-Indicating HPLC Method for Imidapril and Its Degradation Products Using a Design of Experiment (DoE) Approach

Published: August 2017

Abstract
The present work focused on the application of design of experiment (DoE) principles to the development and optimization of a stability-indicating method (SIM) for the drug imidapril hydrochloride and its degradation products (DPs). The resolution of peaks for the DPs and their drug in a SIM can be influenced by many factors. The factors studied here were pH, gradient time, organic modifier, flow rate, molar concentration of the buffer, and wavelength, with the aid of a Plackett–Burman design. Results from the Plackett–Burman study conspicuously showed influence of two factors, pH and gradient time, on the analyzed response, particularly, the resolution of the closely eluting DPs (DP-5 and DP-6) and the retention time of the last peak. Optimization of the multiresponse processes was achieved through Derringer’s desirability function with the assistance of a full factorial design. Separation was achieved using a C18 Phenomenex Luna column (250 × 4.6 mm id, 5 µm particle size) at a flow rate of 0.8 mL/min at 210 nm. The optimized mobile phase composition was ammonium–acetate buffer (pH 5) in pump A and acetonitrile–methanol (in equal ratio) in pump B with a run time of 40 min using a gradient method.

Multimodal analysis of metaphors in political-religious discourse: a cognitive-semiotic approach
Authors: Avelar Maíra , Mendes Paulo Henrique Aguiar 
Published: August 2017

<p>This paper analyzes the interrelation between gestures and speech in the construction of multimodal metaphors in the “legislative session” genre. Based on Multimodal Semiotic Blending (MSB), an adaptation of Brandt and Brandt’s (2005) model (MIRANDA; MENDES, 2014; AVELAR, in press), an illustrative analysis of the multimodal metaphors found in the sessions was performed, focusing on the verbal and gestural resources used by the participants. To do so, five scenes were selected from two legislative<br />sessions performed by two so-called “Representative-pastors” of the Brazilian House of Representatives: Marco Feliciano and Silas Malafaia. Finally, the metaphors and the gestures performed by both politicians were compared. The conclusion reached in this study demonstrated how MSB can be relevant when analyzing the iconicity of material resources (mainly gestures) used by the participants.</p><p><br />Keywords: Cognitive Semiotics.

Wittgenstein on Metaphor
Authors: Gurgel Diogo de França 
Published: August 2017

<p>In this work, I examine Wittgenstein’s possible contributions to an elucidation of the grammatical status of certain metaphors – often found in theoretical and speculative texts – which resist an approach based on the assumption of a clear split between the fields of pragmatics and semantics. I take as examples of works that depart from this assumption Elizabeth Camp’s Contextualism, Metaphor and What is said (which explores the lines suggested by Paul Grice), and John Searle’s Expression and Meaning. Both rely on a distinction between speaker’s meaning (utterance meaning) and sentence meaning to explain the nature of metaphor. They assume that the very metaphorical operation involves meaning something instead of saying something. But it is anything but obvious that, when we consider, e.g., the following metaphor of Philosophical Investigations: “A picture held us prisoners” (§115), we can assume that we are facing a non-descriptive use of language. I argue that Wittgenstein himself can provide us with tools to examine a possible descriptive function of this kind of sentence when he develops his grammatical research methods which: a) are not focused on the linguistic dimension of a sentence but on the linguistic dimension of discourse; b) bring up the issue of language learning; c) lead us to ask if certain metaphors could not work as modifiers of convictions, i.e., if they could not act directly on what Wittgenstein once called Weltbild.</p><p><br />Keywords: Metaphor.

<p>Neste estudo, pretende-se desenhar uma abordagem da metáfora na interface metateórica (COSTA, 2007). Pretende-se ilustrar como, por meio do diálogo interdisciplinar, novas abordagens para a metáfora podem ser construídas. Para tanto, de um lado, apresentam-se os fundamentos da Pragmática que explicam como se processam os enunciados metafóricos e, de outro, apresentam-se achados em Neurociência que, por sua vez, descrevem, via coarse-coding hypothesis, os correlatos neurais desse<br />processamento. Postas em diálogo, dessas diferentes áreas emergem propriedades complexas que podem contribuir para o aprofundamento do potencial descritivo e explanatório da abordagem interdisciplinar. Além disso, pode-se também reacender e complexificar as possibilidades de diálogo entre teorias, à medida que propriedades complexas interagem entre si.</p><p><br />Palavras-chave: Metáfora.

Functional effects, prepositional semantics, and metaphorical containment in Brazilian Portuguese: the case of em, dentro de, and fora de
Authors: Oliveira Aparecida de Araújo 
Published: August 2017

<p>I analyzed conventional metaphorical expressions in Brazilian Portuguese having lexicalized functional effects of spatial scenes as complements of the prepositions dentro de [inside], em [in, on, at], and fora de [out of]. The functional effects investigated were ‘protection’, ‘covering/hiding’, ‘control’, and ‘envelopment’, which constitute the family resemblance concept of Containment. I provided a cognitive account of these conventional expressions in terms of primary metaphors such as invisible is inside and<br />uncontrolled is outside, emerging through experiential correlation in primary scenes. I described twelve meanings based on the container image schema, four based on the verticality schema, and four based on the nonimagetic notion of ‘non-existence’. Contradicting my initial expectations, the corpus-based analysis revealed little overlapping between em and sob [under], and fora de and sem [without]. However, the study confirmed the asymmetry between the prepositions meaning ‘in’ and those meaning ‘out’.</p><p>Keywords: Metaphor. Experiential correlation. Containment functional relation.

Irrigation, risk aversion, and water right priority under water supply uncertainty
Authors: Li Man , Xu Wenchao , Rosegrant Mark W. 
Published: August 2017

AbstractThis paper explores the impacts of a water right's allocative priority—as an indicator of farmers' risk‐bearing ability—on land irrigation under water supply uncertainty. We develop and use an economic model to simulate farmers' land irrigation decision and associated economic returns in eastern Idaho. Results indicate that the optimal acreage of land irrigated increases with water right priority when hydroclimate risk exhibits a negatively skewed or right‐truncated distribution. Simulation results suggest that prior appropriation enables senior water rights holders to allocate a higher proportion of their land to irrigation, 6 times as much as junior rights holders do, creating a gap in the annual expected net revenue reaching up to $141.4 acre−1 or $55,800 per farm between the two groups. The optimal irrigated acreage, expected net revenue, and shadow value of a water right's priority are subject to substantial changes under a changing climate in the future, where temporal variation in water supply risks significantly affects the profitability of agricultural land use under the priority‐based water sharing mechanism.
