Narrating the Past and the Future: The Position of the religions orientales and the mystères païens in the Evolutionary Histories of Religion of Franz Cumont and Alfred Loisy
Authors: Lannoy Annelies , Bonnet Corinne 
Published: April 2018

Abstract:In their grand narratives on the ancient history of religions, the Belgian historian of religions, Franz Cumont (1868 – 1947) and his French colleague and correspondent, Alfred Loisy (1857 – 1940) both assigned a prominent place to the so-called pagan mystery religions. This paper seeks to identify the specific theories of religion and the deeper motivations underpinning Cumont’s and Loisy’s historiographical construction of the mystery cults as a distinct type of religion within their evolutionary accounts of the history of religions. Through a comparative analysis of their rich correspondence (1908 – 1940) and a selection of their publications, we demonstrate how their historical studies of the religious transformations in the Roman Empire, their in-depth dialogues in the troubled times in which they lived, and their philosophical views on the overall history and future of religion, were in fact mutually constitutive.
Anthropomorphism, Theatre, Epiphany: From Herodotus to Hellenistic Historians
Authors: Koch Piettre Renée 
Published: April 2018

Abstract:This paper argues that, beginning with the Euripidean deus ex machina, dramatic festivals introduced a new standard into epiphanic rituals and experience. Through the scenic double énonciation, gods are seen by mythical heroes as gods, but by the Athenian spectators as costumed actors and fictive entities. People could scarcely believe these were ‘real’ gods, but would have no doubt been impressed by the scenic machinery. Thus the Homeric theme of a hero’s likeness to the gods developed into the Hellenistic theme of the godlike ruler’s (or actor’s) theatrical success (or deceit). So in the Athenians’ Hymn to Demetrius Poliorcetes, a victorious ruler entering a city is welcomed as a better god than the gods themselves. The simultaneous rise in popularity of paradoxical stories and experiences in the Hellenistic period was grounded not in believing, but in disbelieving – a phenomenon associated with antiquarian interests, the self-publicity of religious sanctuaries, or amazed credulity. People were increasingly drawn to ‘real’ gods, leading to long pilgrimages and extensive financial outlay (in the mysteries) in order to see them. I investigate this phenomenon by focusing upon fragments of the ‘mimetic’ or ‘tragic’ Greek historians that survive from this period.
Martin P:n Nilsson und die Wiederbesetzung des Lehrstuhls für klassische Philologie in Heidelberg 1924/1925
Authors: Dürkop Martina 
Published: April 2018

Abstract:The correspondence between Otto Weinreich and Martin Persson Nilsson suggests that Nilsson was to be appointed to the chair of Classical Philology in Heidelberg in winter 1924 – 1925. But we do not find any official papers at the Ministry of Culture or at the University of Heidelberg. So we ask why the university should offer a chair to this worldwide renowned scientist. Was he to breathe new life into religious studies or was he simply meant as a figurehead who opens the door of return to international collaboration? Since valuable documents are missing, we trust in letters filling the gap in our knowledge of this appointment.

Abstract
This study assessed the constraints faced by commercial poultry farmers in waste management practices in Kogi and Kwara States, Nigeria. A structured questionnaire was used to elicit information from randomly selected 138 and 125 registered commercial poultry farmers from both states, giving a total sample size of 263 for the study. Both descriptive and inferential statistics were used to analyse the data for the study. Results of analysis showed that mean age was 46.7 years, farm size was 991 birds and poultry farming experience was 11 years. Also, majority were male (82.0 %), married (88.8 %), had tertiary education (94.0 %). Mean age of farm was 9 years. Poultry dropping was the most (mean = 2.36) generated waste in the study area. The most prevalent waste management methods used by poultry farmers were open dumping around the farm (mean = 2.23), giving wastes free to the public as farmyard manure (mean = 2.16), poultry wastes are dumped in a nearby bush (mean = 2.09), dead birds are buried in a pit near the farm (mean = 2.08), dead birds are thrown into a nearby bush (mean = 2.01) and dead birds are burnt inside a pit or in a heap near the farm (mean = 2.01). The major constraints faced by farmers in waste management practices were lack of awareness on how to use the wastes productively (mean = 4.06), no agricultural land nearby where wastes can be used (mean = 3.69), excessive odour from waste (mean = 3.66), high cost of chemical treatment (mean = 3.56), high transportation cost (mean = 3.24) and high cost of private waste management agencies (mean = 3.01). Results of Multiple Regression Analysis show that poultry wastes used as farm yard manure, burnt and buried in a pit, sun-dried and burnt and given freely to interested farm workers had inverse significant relationship to constraints while dumping of poultry wastes around the farm, nearby bush and to animals such as dogs had positive significant relationship to constraints faced by respondents in waste management. The study concluded that the level of constraints faced by commercial poultry farmers in waste management practices was high (mean = 3.39) in the study area. The study recommends among others the needs for existing poultry farmers association to include programmes that will enlighten members on poultry waste management practices that will not have negative effect upon their birds and the environments.
Generalized dynamic observer design for quasi-LPV systems
Authors: Pérez-Estrada A.-J. , Osorio-Gordillo G.-L. , Darouach M. , Olivares-Peregrino V.-H. 
Published: April 2018

Abstract
This paper presents a new generalized dynamic observer (GDO) for quasi-linear parameter varying (LPV) systems. It generalises the structures of the proportional observer (PO) and proportional integral observer (PIO). The design of the GDO is derived from the solution of linear matrix inequalities (LMIs) and the solution of the algebraic constraints obtained from the estimation error analysis. The efficiency of the proposed approach is illustrated by a numerical example.
Comparative studies on variability, phylogenesis, and correlated mutations of neuraminidases from influenza virus type A
Authors: Filip Rafał , Leluk Jacek 
Published: April 2018

Abstract
Neuraminidase (NA) is an important protein for the replication cycle of influenza A viruses. NA is an enzyme that cleaves the sialic acid receptors; this process plays a significant role in viral life cycle. Blocking NA with a specific inhibitor is an effective way to treat the flu. However, some strains show resistance to current drugs. Therefore, NA is the focus for the intense research for new antiviral drugs and also for the explanation of the functions of new mutations. This research focuses on determining the profile of variability and phylogenetic analysis and finding the correlated mutations within a set of 149 sequences of NA belonging to various strains of influenza A virus. In this study, we have used the original programs (Corm, Consensus Constructor, and SSSSg) and also other bioinformatics software. NA proteins are characterized by various levels of variability in different regions, which was presented in detail with the aid of ConSurf. The use of four independent methods to create the phylogenetic trees gave some new data on the evolutionary relationship within the NA family proteins. The search for correlated mutations shows several potentially important correlated positions that were not reported previously to be significant. The use of such an approach can be potentially important and gives new information regarding NA proteins of influenza A virus.

Abstract
The goal of the research described in the article was to develop the device for the automatic scarification of acorns and computer vision-based assessment of their viability. The color image of the intersection of the tissue of cotyledons was selected as a key feature for separating healthy seeds from the spoiled ones. Because the device is being designed for the diagnosis of high volume of seeds aiming at producing high-quality seedlings, several assessment criteria of the overall design of the automaton are being assessed. The basic one is the overall accuracy of viability recognition. The other refers to particular functions implemented in the model of the device being described.

Potential Parenthood and Career Progression of Men and Women – A Simultaneous Hazards Approach
Authors: Biewen Martin , Seifert Stefanie 
Published: April 2018

Abstract
We analyze individual career transitions of men and women in Germany. Our particular focus is on the association of upward, downward and horizontal job changes with individual fertility. In contrast to most of the literature, we focus on potential rather than realized fertility. Based on mixed multivariate proportional hazard models with competing risks, we find a significant negative relationship between the contemporaneous probability of having a child and horizontal career transitions for women and a positive significant association of the hazard of parenthood with upward career transitions for men. These effects persist when we apply fixed-effects panel data models allowing for correlation of individual parenthood hazards with unobserved individual characteristics. Our results suggest clear gender differences in the relationship between career patterns and potential fertility.
Bibliothek im Wandel: Die (Weiter-)Entwicklung der Bereichsbibliothek Medizin der SUB Göttingen als Lern-, Arbeits- und Kommunikationsort von 2013 bis heute
Authors: Härter Dagmar 
Published: April 2018

Zusammenfassung
Der digitale Wandel und das veränderte Nutzerverhalten stellen Bibliotheken schon seit längerer Zeit vor völlig neue Herausforderungen. Traditionelle Arbeits- und Aufgabenbereiche verlieren an Bedeutung bzw. entfallen, dafür kommen andere Tätigkeiten hinzu, auf die das Personal teilweise erst vorbereitet werden muss. Wie man es mit einem immer kleiner werdenden Mitarbeiterpool dennoch schaffen kann, die Bibliothek weiterhin als attraktiven Lern-, Arbeits- und Kommunikationsort zu erhalten und auszubauen, zeigt dieser Erfahrungsbericht exemplarisch am Beispiel der Bereichsbibliothek Medizin in Göttingen.
Interpunktion und Textsegmentierung im frühen deutschsprachigen Prosaroman
Authors: Voeste Anja 
Published: April 2018

AbstractOn the threshold of the sixteenth century, publishers met the demands of a ready market: They provided a selection of German prose novels and adapted their publications to a broader, less homogeneous readership. Against this backdrop, the article discusses the still evolving system of segmentation (primarily punctuation). When punctuation was inserted into a text, it might have been the typesetter’s task to work out a system of usage. The typesetters reacted to this new challenge by using several, even contradicting principles in a bottom-up-process ofbricolage: They separated prosodic, semantic, syntactic or memory units while simultaneously considering aesthetic demands (justification).
abbreviatio
Authors: Frick Julia 
Published: April 2018

Abstract
Apart from a few exceptions, abridged versions of courtly epics have not yet been of great interest to mainstream research. Yet, they represent a historical literary phenomenon that documents an independent type of courtly narrative from the very beginnings of the genre. The simultaneous narrative schemes they feature can be traced to contemporary Latin poetics, in which the expansion (amplificatio) and abridging (abbreviatio) of material are described as two basic techniques used in the process of adapting narrative texts. This article presents some initial observations on the elaboration of brevitas poetics, which could offer a complete overview of the courtly epic of the 13th century.
Purification of Tea saponins and Evaluation of its Effect on Alcohol Dehydrogenase Activity
Authors: Yuan Chuanxun , Li Yan , Li Qingchuan , Jin Risheng , Ren Lili 
Published: April 2018

AbstractTea saponins, extracted from a Camellia oleifera cake, were found to have a potent effect on de-alcoholic activity. To obtain highly pure tea saponins, which can better maintain the activity of alcohol dehydrogenase (ADH), this paper presents an extraction method for tea saponins using deionized water as the extraction agent and a two-stage precipitation method, including ethanol precipitation and CaO precipitation. The optimum conditions for ethanol precipitation were 95% alcohol, a duration of 1.5h and a solid/liquid ratio of 1:4; while the optimum conditions for CaO precipitation were a duration of 2h and an NH4HCO3/CaO ratio of 2:1. Under the optimum conditions, the content of saponins was 87.58%. The results showed that the greater the amount of tea saponins and the higher its purity, the more significant its activating effect on ADH. When the purity of tea saponins was above 75%, it activated ADH. It indicated that the de-alcoholic mechanism of tea saponins is associated with the activity of ADH. Furthermore, the study characterized the structure of tea saponins by UV absorption and Fourier Transform Infrared (FTIR) spectrometry and LC-MS.
Secretion of full-length Tau or Tau fragments in cell culture models. Propagation of Tau in vivo and in vitro
Authors: Pérez Mar , Medina Miguel , Hernández Félix , Avila Jesús 
Published: April 2018

AbstractThe microtubule-associated protein Tau plays a crucial role in stabilizing neuronal microtubules. In Tauopathies, Tau loses its ability to bind microtubules, detach from them and forms intracellular aggregates. Increasing evidence in recent years supports the notion that Tau pathology spreading throughout the brain in AD and other Tauopathies is the consequence of the propagation of specific Tau species along neuroanatomically connected brain regions in a so-called “prion-like” manner. A number of steps are assumed to be involved in this process, including secretion, cellular uptake, transcellular transfer and/or seeding, although the precise mechanisms underlying propagation of Tau pathology are not fully understood yet. This review summarizes recent evidence on the nature of the specific Tau species that are propagated and the different mechanisms of Tau pathology spreading.
A Technology Acceptance Model of common bean growers’ intention to adopt Integrated Production in the Brazilian Central Region
Authors: Silva Aluisio Goulart , Canavari Maurizio , Sidali Katia Laura 
Published: April 2018

SummaryThe Brazilian government encouraged the Integrated Production (IP) farming system adoption to mitigate the negative environmental impacts of intensive bean production in irrigated areas of the Brazilian savanna. By ensuring food-safety and the use of sustainable agricultural practices, IP may strengthen national agriculture competitiveness. Regardless of the government efforts to promote IP in the main agricultural regions and among the largest food growers, only few slowly adopted it. Therefore, studying the process of technology adoption is important to identify possible problems that could affect adoption and diffusion of this farming system. We applied a Technology Acceptance Model (TAM) to explain the adoption and use of IP by the common beans growers from one of the most important bean production regions in Brazil. Ninety-three interviews were administered to different actors involved in beans production. A Structural Equation Model (SEM) following a confirmatory factor analysis (CFA) was used to identify the relationship between factors. The findings suggest that respondents have positive perceptions toward adopting IP. Perceived usefulness has a positive impact on attitude, and attitudes affect behavioral intention. However, the proposed model only partially explains IP adoption intentions.

Published: April 2018

Abstract
Continuous and intensive selective breeding reduces the genetic diversity of cultivated Pyropia stock, thereby increasing its susceptibility to diseases, and hindering the sustainable development of the Pyropia industry. To develop new Pyropia germplasms with desirable agronomic traits, a new Pyropia yezoensis strain, “Huangyou No. 1” was bred from a wild subtidal population. In this study, the genetic diversity of this strain was analyzed using AFLP. Totally, 249 loci were obtained, of which 248 were polymorphic with a polymorphism rate of 99.6%, using seven primer pairs. The intra-population polymorphism rates of the populations Wild 1 and Wild 2 were the highest (47.39% and 59.44%, respectively), while they were relatively low (20.88–24.5%) in the cultivated populations. The genetic distances between the breeding Pyropia populations cultivated in the same aquaculture farm were low. Specifically, the F2 offspring of “Huangyou No. 1” and the control cultivar, cultivated using the “never-drying” protocol, were genetically distant from the other populations, including that from the same seedlings, yet cultivated using the “periodic-drying” protocol. The never-drying cultivation protocol had a high likelihood of influencing genetic diversity of Pyropia yezoensis.
Loss of mass and performance in skeletal muscle tissue: a continuum model
Authors: Giantesio Giulia , Marzocchi Alfredo , Musesti Alessandro 
Published: April 2018

Abstract
We present a continuum hyperelastic model which describes the mechanical response of a skeletal muscle tissue when its strength and mass are reduced by aging. Such a reduction is typical of a geriatric syndrome called sarcopenia. The passive behavior of the material is described by a hyperelastic, polyconvex, transversely isotropic strain energy function, and the activation of the muscle is modeled by the so called active strain approach. The loss of ability of activating of an elder muscle is then obtained by lowering of some percentage the active part of the stress, while the loss of mass is modeled through a multiplicative decomposition of the deformation gradient. The obtained stress-strain relations are graphically represented and discussed in order to study some of the effects of sarcopenia.
On preconditioner updates for sequences of saddle-point linear systems
Authors: Simone Valentina De , Serafino Daniela di , Morini Benedetta 
Published: April 2018

Abstract
Updating preconditioners for the solution of sequences of large and sparse saddle- point linear systems via Krylov methods has received increasing attention in the last few years, because it allows to reduce the cost of preconditioning while keeping the efficiency of the overall solution process. This paper provides a short survey of the two approaches proposed in the literature for this problem: updating the factors of a preconditioner available in a block LDLT form, and updating a preconditioner via a limited-memory technique inspired by quasi-Newton methods.
Comparison of minimization methods for nonsmooth image segmentation
Authors: Antonelli L. , De Simone V. 
Published: April 2018

Abstract
Segmentation is a typical task in image processing having as main goal the partitioning of the image into multiple segments in order to simplify its interpretation and analysis. One of the more popular segmentation model, formulated by Chan-Vese, is the piecewise constant Mumford-Shah model restricted to the case of two-phase segmentation. We consider a convex relaxation formulation of the segmentation model, that can be regarded as a nonsmooth optimization problem, because the presence of the l1-term. Two basic approaches in optimization can be distinguished to deal with its non differentiability: the smoothing methods and the nonsmoothing methods. In this work, a numerical comparison of some first order methods belongs of both approaches are presented. The relationships among the different methods are shown, and accuracy and efficiency tests are also performed on several images.
A fractional spline collocation-Galerkin method for the time-fractional diffusion equation
Authors: Pezza L. , Pitolli F. 
Published: April 2018

AbstractThe aim of this paper is to numerically solve a diffusion differential problem having time derivative of fractional order. To this end we propose a collocation-Galerkin method that uses the fractional splines as approximating functions. The main advantage is in that the derivatives of integer and fractional order of the fractional splines can be expressed in a closed form that involves just the generalized finite difference operator. This allows us to construct an accurate and efficient numerical method. Several numerical tests showing the effectiveness of the proposed method are presented.
