Thermosensory perception regulates speed of movement in response to temperature changes inDrosophila melanogaster
Authors: Soto-Padilla Andrea , Ruijsink Rick , Sibon Ody C. M. , van Rijn Hedderik , Billeter Jean-Christophe
Published: April 2018

Temperature influences physiology and behavior of all organisms. For ectotherms, which lack central temperature regulation, temperature adaptation requires sheltering from or moving to a heat source. As temperature constrains the rate of metabolic reactions, it can directly affect ectotherm physiology and thus behavioral performance. This direct effect is particularly relevant for insects whose small body readily equilibrates with ambient temperature. In fact, models of enzyme kinetics applied to insect behavior predict performance at different temperatures, suggesting that thermal physiology governs behavior. However, insects also possess thermosensory neurons critical for locating preferred temperatures, showing cognitive control. This suggests that temperature-related behavior can emerge directly from a physiological effect, indirectly as consequence of thermosensory processing, or through both. To separate the roles of thermal physiology and cognitive control, we developed an arena that allows fast temperature changes in time and space, and in which animals' movements are automatically quantified. We exposed wild-type and thermosensory receptor mutants Drosophila melanogaster to a dynamic temperature environment and tracked their movements. The locomotor speed of wild-type flies closely matched models of enzyme kinetics, but the behavior of thermosensory mutants did not. Mutations in thermosensory receptor dTrpA1 (Transient receptor potential) expressed in the brain resulted in a complete lack of response to temperature changes, while mutation in peripheral thermosensory receptor Gr28b(D) resulted in diminished response. We conclude that flies react to temperature through cognitive control, informed by interactions between various thermosensory neurons, whose behavioral output resembles that of enzyme kinetics.

Authors: Claus Waldemar , Gonzalez Gustavo , Spekuljak Pablo
Published: April 2018

El presente artículo constituye un primer ejercicio de mapeo de las principales rutas asociadas al tráfico de drogas que tuvieron como uno de sus segmentos a la  Argentina entre 2000 y 2014. A partir de la noción de rutas ordenamos en un mismo esquema una serie de datos significativos para describir el funcionamiento de estos mercados: el tipo de sustancias transportadas, los puntos de inicio y de destino, las distintas modalidades de transporte, los obstáculos que las organizaciones y redes de actores deben sortear para el tránsito de las sustancias (considerando entre ellos el rol de las fronteras inter-estatales), así como también la distribución de las diferentes etapas de producción, distribución y consumo a lo largo de sus diversos segmentos. Nos enfocamos, por último, en uno de los emergentes del análisis del período: la importancia del vínculo entre economías legales e ilegales en la estructuración de estos mercados.

The study of the Qur'an was originally derived from mosques, musholla or pesantren. Subsequent developments emerged Taman Kanak-kanak Al-Quran / Taman Pendidikan Al-Quran (TKA / TPA). Beginning in the early 2000s the spirit of learning Qur'an began to appear in formal educational institutions. Islamic private schools and madrasah began to intensify the study of the Qur'an which includes reading, writing and memorizing the Qur'an. The methods used are also very varied, among them are the Iqra method and Ummi method. This study intends to compile the effectiveness of learning the Qur'an using Iqra 'MIN Yogyakarta II method and Ummi SDIT Al-Khairaat Yogyakarta method. The results of this study indicate: from the side of the process, learning the Qur'an using Ummi method in SDIT Al-Khairaat run more effectively than in MIN Yogyakarta II using Iqra method. In terms of results, the study of the Qur'an with Iqra' method in MIN Yogyakarta II is as good or as effective as the result of learning Al-Qur'an by using Ummi method in SDIT Al-Khairaat Yogyakarta.
Key factors in learners’ satisfaction with the e-learning system at the University of Dar es Salaam, Tanzania
Authors: Mtebe Joel S. , Raphael Christina
Published: April 2018

This study aimed to identify key factors that have an influence on learners’ satisfaction with the e-learning system at the University of Dar es Salaam, Tanzania, using a modified, updated DeLone and McLean (D&M) (2003) model. The research model was tested against regression analysis using a sample of 153 enrolled students. The study found that system quality, instructor quality, and service quality had a significant positive effect on learners’ satisfaction, with service quality being the strongest predictor. However, course quality was found to have no significant effect on learners’ satisfaction with the e-learning system. The findings from this study will help institutions that are planning or implementing e-learning systems to enhance learners’ satisfaction and, consequently, increase systems success. The implications of these findings are discussed.
Making it real: The development of a web-based simulated learning resource for occupational therapy students
Authors: Nicola-Richmond Kelli , Watchorn Valerie
Published: April 2018

Equipping students with graduate attributes that ensure they are ready to work in complex health environments is highly important. Recently there has been increased use of simulation in health education to assist in the acquisition of graduate attributes, and to provide meaningful and authentic learning opportunities. The Deakin University Occupational Therapy program developed a unique web-based Occupational Therapy Simulations for Learning resource. This resource comprised 18 filmed scenarios that were previously non-existent or only available to students in written format. The scenarios depict people with a range of health conditions, mock graduate interviews, and occupational therapists conducting simulated clinical assessments and interventions. This study explored the effectiveness of the resource in the development of empathy, active listening, and information gathering skills. It also compared experiences of students and academics who had previously used written case studies. Survey results demonstrated statistically significant differences in relation to the realness of case studies, understanding how the client was feeling, development of empathy, clinical assessment skills, and the usefulness of the resource overall. This study demonstrates that the use of simulated case studies offers authentic learning for occupational therapy students and promotes development of key graduate attributes.
Pseudo-embeddings of the (point, k-spaces)-geometry of PG(n, 2) and projective embeddings of DW(2n − 1, 2)
Authors: Bruyn Bart De
Published: April 2018

We classify all homogeneous pseudo-embeddings of the point-line geometry defined by the points and k-dimensional subspaces of PG(n, 2), and use this to study the local structure of homogeneous full projective embeddings of the dual polar space DW(2n − 1, 2). Our investigation allows us to distinguish n possible types for such homogeneous embeddings. For each of these n types, we construct a homogeneous full projective embedding of DW(2n − 1, 2).

Mutagenesis-induced conformational change in domain B of a pullulan-hydrolyzing α-amylase TVA I
Authors: Tonozuka Takashi , Nihira Takanori , Mizuno Masahiro , Nishikawa Atsushi , Kamitori Shigehiro
Published: April 2018

An α-amylase from Thermoactinomyces vulgaris, TVA I, hydrolyzes both α-1,4- and α-1,6-glucosidic linkages. Two variants of TVA I have been previously constructed, one containing a substitution of three residues, Ala357- Gln359-Tyr360, with Val-Asn-Glu (AQY/VNE), and the other bearing a deletion of 11 residues from Ala363 to Asn373 (Del11). The activities of both AQY/VNE and Del11 for the α-1,4-glucosidic linkage of maltotriose were decreased compared to that of wild-type TVA I, while the activities of the two variants for the α-1,6-glucosidic linkage of a trisaccharide, isopanose, were less significantly altered. Here, we determined the crystal structures of AQY/VNE and Del11. The structure of AQY/VNE was almost isomorphous with that of wild-type TVA I. On the other hand, the structure of Del11 showed that a conformational change in domain B was induced by the 11-residue deletion, causing narrowing of the catalytic cleft. Taken together with the results of kinetic analysis, this narrower catalytic cleft is likely responsible for the preference of the TVA I enzyme for the α-1,6-glucosidic linkage.
Thinking/Tragedy/Thinking Tragedy: Remarks on the Fate of Theory on Stage
Authors: Lehmann Hans-Thies
Published: April 2018

The article thematizes the uniquely complex relation between theory and theatre by focusing on the specific case of theory presented on stage. Part One exposes an aporia of classical aesthetics: the aesthetic object is conceived as different from thought but at the same time it is demanded that its nucleus is thought. Commenting on a particularly telling example of theory on stage: Karl Marx: Das Kapital, Erster Band von Rimini Protokoll (2006), it is argued that the power of the performance is able to uncover under the surface of a seemingly well-known and well-ordered theory a mostly overlooked element of madness. Part Two deals with the Aristotelian gesture of thinking tragedy as a para-logical reality. The ‘logification’ of the aesthetic overlooks (or ‘forgets’) that all theoretical positing loses necessarily its earnest when appearing on stage. The paper concludes with a reflection on the enduring ‘unconscious’ Aristotelianism of the discourse on theatre and tragedy. Drawing on the research of Ulf Schmidt, the irreconcilable contradictoriness of the concepts of nous and fantasia is exposed which leads time and again to the hatred for the unruly playfulness of theatre in the classic tradition. The nobilitation of tragedy by Aristotle as more ‘philosophical’ than historiography must be unmasked as a ‘Trojan horse’ which serves the subordination of the tragic play to the jurisdiction of the philosophical discourse. Resisting theory’s attempt to transform the theatrical play into a mere double of a conceptual contradiction, theatre must insist on its moment of opaqueness, sheer materiality, defiant unreasonability.
Dramatic Measures: Comedy as Philosophical Paradigm
Authors: Street Anna
Published: April 2018

Tragedy’s overwhelming presence, presaged by the conspicuous absence of Aristotle’s treatise on comedy, has dominated the debate between philosophy and poetry ever since Plato, making tragedy the dominant paradigm for philosophical and performance practices. Over the last century, the gradual blurring of genre distinctions has led to George Steiner’s declaration of the ‘death of tragedy’ and to J. L. Styan’s recognition of the emergence of ‘dark comedy’, giving rise to a growing body of research on comedy. Nevertheless, despite the unprecedented attention, the prejudices against comedy run wide and deep, from philosophical neglect to high-brow conceptions of art all the way to underlying economies of power and social regulation. In consequence, comedy has been side-stepped as an inferior genre or mode, or rehabilitated as a truer or newer form of the tragic. The present study attempts to frame this prejudice as the result of theories of aesthetics and ethics which systematically exclude the comic vision, claiming that it is possible to trace a distinct corollary between the development of theories of genre and the development of philosophical aesthetic categories. The emphasis on the beautiful and the sublime, and its corresponding brand of ethics, can be linked to the flourishing of theories of tragedy, while the systematized rejection of the ugly, the ridiculous, and the ethically ambiguous can be shown to correspond to the floundering of theories of comedy, which remained largely neglected for over two thousand years. Much more than mere literary genres, the terms comedy and tragedy, when applied to the history of Western civilization, reveal the extent of our penchant for the speculative to the detriment of the actual.

A k-Inflated Negative Binomial Mixture Regression Model: Application to Rate–Making Systems
Authors: Payandeh Najafabadi Amir T. , MohammadPour Saeed
Published: April 2018

This article introduces a k-Inflated Negative Binomial mixture distribution/regression model as a more flexible alternative to zero-inflated Poisson distribution/regression model. An EM algorithm has been employed to estimate the model’s parameters. Then, such new model along with a Pareto mixture model have employed to design an optimal rate–making system. Namely, this article employs number/size of reported claims of Iranian third party insurance dataset. Then, it employs the k-Inflated Negative Binomial mixture distribution/regression model as well as other well developed counting models along with a Pareto mixture model to model frequency/severity of reported claims in Iranian third party insurance dataset. Such numerical illustration shows that: (1) the k-Inflated Negative Binomial mixture models provide more fair rate/pure premiums for policyholders under a rate–making system; and (2) in the situation that number of reported claims uniformly distributed in past experience of a policyholder (for instance

k
1

=

$k_1=1$

and

k

=
1

$k_2=1$

instead of

k

$k_1=0$

and

k

$k_2=2$

). The rate/pure premium under the k-Inflated Negative Binomial mixture models are more appealing and acceptable.

“One Has To Be So Terribly Religious To Be An Artist”: Divine Inspiration and theophilia in Aelius Aristides’ Hieroi Logoi
Authors: Petridou Georgia
Published: April 2018

This paper deals with the close link between divine epiphany and artistic inspiration in the life and work of one of the most renowned rhetoricians of the second century AD, Aelius Aristides. The argument in a nutshell is that when Aristides lays emphasis on the divinely ordained character of the Hieroi Logoi, in particular, and his literary and rhetorical composition, in general, he taps into a rich battery of traditional theophilic ideas and narratives (oral and written alike). These narratives accounted for the interaction of divine literary patrons and matrons with privileged members of the intellectual elite to provide thematic or stylistic guidance to their artistic enterprises. Thus, Aristides makes wider claims about his own status of theophilia (lit. ‘the state of being dear to the gods’), a status that was much-praised and much-prized in the Graeco-Roman world, and one that functioned as a status-elevating mechanism in the eyes of both his contemporaries and posterity. Furthermore and on a different level, he also utilizes his theophilic aspirations to elevate his prose-hymns (a genre he invented) to the higher and already established level of encomiastic poetry, which Greeks regarded for centuries as fit for the ears of the gods.
New observations and asteroseismic analysis of the subdwarf B pulsator PG 1219+534
Authors: Van Grootel Valérie , Péters Marie-Julie , Green Elizabeth M. , Charpinet Stéphane , Brassard Pierre , Fontaine Gilles
Published: April 2018

We present a new asteroseismic modeling of the hot B subdwarf (sdB) pulsator PG 1219+534, based on a 3- month campaign with the Mont4K/Kuiper combination at Mt Bigelow (Arizona) and on updated atmospheric parameters from high S/N low and medium resolution spectroscopy. On the basis of the nine independent pulsation periods extracted from the photometric light curve, we carried out an astroseismic analysis by applying the forward modeling approach using our latest (third and fourth generation) sdB models. Atmospheric parameters (Teff = 34 258 ± 170 K, log g = 5.838 ± 0.030) were used as independent constraints, as well as partial mode identification based on observed multiplet structures we ascribed to stellar rotation. The optimal model found is remarkably consistent between various analyses with third and fourth generation of sdB models, and also with previously published analysis with second generation sdB models. It corresponds to a sdB with a canonical mass (0.46 ± 0.02 M⊙), rather thin H-He envelope (log q(envl) = −3.75 ± 0.12), and close to He-burning exhaustion (Xcore(C + O) = 0.86 ± 0.05).We also investigate the internal rotation of the star.We find that PG 1219+534 rotates very slowly (Prot = 34.91 ± 0.84 days) and that solid-body rotation is reached at least down to ∼60% of the radius.
Comparative Analysis of Savers and Non-Savers among Tomato Farmers in Ghana
Authors: Aidoo-Mensah Daniel
Published: April 2018

The study sought to examine the differences between savers and non-savers among a cross-section of 562 farmers randomly selected from six districts in three regions (Ashanti, Brong Ahafo and Upper East) of Ghana. By means of descriptive statistics in the form of frequencies and percentages, the study segregated the respondents into savers and non-savers and Kendall coefficient of concordance was employed to identify the motives of saving among savers and non-saving among non-savers. In order to test whether savers and non-savers differ in relationship to some key socio-economic demographic characteristics, a series of Pearson’s Chi-tests for independence were employed. Finally, by the application of economic-psychology theory on financial savings through binary logistic regression, the study examined empirical differences between savers and non-savers. The study found out that in terms of a key economic variable, that is, income generated from tomato production, savers tend not to differ from non-savers. The issue then is since savers are faced with similar economic challenges relating to their income generating activities, but still manages to save, then the differences between savers and non-saver go beyond economic reasons. Thus, the distinction between saving and non-saving which is underlined by psychological traits have been found to be mainly behavioural and demographic in nature conveying the idea that rural households themselves have a significant part to play with regards to forming, improving and maintaining their savings habits.
An in Situ Crystal Growth of Metal Organic Frameworks-5 on Electrospun PVA Nanofibers
Authors: Talmoudi Hanen , Khenoussi Nabyl , Adolphe Dominique , Said Ayoub Haj , Schacher Laurence
Published: April 2018

In this study, a simple, general and straightforward method for growing metal-organic frameworks (MOFs) crystals directly on nanofibers is presented. A chelating polymer was first blent with metal cation and then electrospun. The obtained nanofibers were immersed in a linker solution. Metal cations were released and the metal-organic frameworks crystals were grown on the fibers’ surface. In this work, this method was tested with polyvinyl alcohol as chelating polymer, Zn2+ as metal cation and Terephthalic acid as linker. The pair cation/linker corresponds to the MOF-5. The latter is a robust metal organic framework formed from Zn4O nodes with 1,4-benzodicarboxylic acid struts between the nodes. SEM images revealed that the MOF-5 nanocrystals have grown along the PVA/Zn2+ nanofibers that served as the crystals’ growth template by providing the Zn2+ ions. This result was also confirmed by infrared spectroscopy, which indicates the presence of characteristic bands of MOF-5 in the modified nanofibers spectrum. Moreover, the X-ray diffraction showed that MOF-5 material was well crystallized on the nanofibers surface according to a cubic symmetry with a space group Fm-3m and a lattice constant a = 25.8849 Å.

From acceleration-based semi-active vibration reduction control to functional observer design
Authors: Wang Yebin , Utsunomiya Kenji
Published: April 2018

This work investigates a functional estimation problem for single input single output linear and nonlinear systems, motivated by its enabling role in acceleration-based semi-active control. Solvability of a linear functional estimation problem is studied from a geometric approach, where the functional dynamics are derived, decomposed, and transformed to expose structural properties. This approach is extended to solve a challenging nonlinear functional observer problem, combining with the exact error linearization. Existence conditions of nonlinear functional observers are established. Simulation verifies existence conditions and demonstrates the effectiveness of the proposed functional observer designs.
Observer design for monocular visual inertial SLAM
Authors: Fink Geoff , Franke Mirko , Lynch Alan F. , Röbenack Klaus
Published: April 2018

This paper examines the state estimation problem for unmanned aerial vehicles when commonly used positioning systems such as the global positioning system or indoor motion capture systems are unavailable. The proposed method uses inertial sensor measurements along with scaled position measurements from an onboard computer vision system which implements visual simultaneous localization and mapping. A state transformation puts the system into a linear time-varying form which simplifies observability analysis and allows for an observer design with sufficient conditions for convergence. The proposed design is validated by simulation.

Published: April 2018

Thalamotomy is a neurosurgical procedure used in the treatment of advanced Parkinson’s disease (PD). The aim of our research is to evaluate the early impact of a lesion in the ventrointermedial nucleus (VIM) of the thalamus on cognitive and motor function in people with PD. Sixty patients who qualified for right- or left-sided VIM thalamotomy were involved in the study. The cognitive and motor functions of each patient were assessed both prior to and following the surgical procedure. Twenty-nine PD patients without ablative treatment were qualified for the comparison group, and 57 neurologically healthy individuals were assigned to the control group. The following tests were carried out: Mini Mental State Examination, Benton Visual Retention Test, Stroop Color and Word Test, Trail Making Test A&B, and Rey Auditory Verbal Learning Test. Statistically significant differences were found in reaction time, visual-spatial working memory, auditory-verbal memory, and overall level of cognitive function when comparing the results of tests carried out before and after thalamotomy and when comparing patients who had undergone surgery with untreated or healthy individuals. In patients with right-sided and left-sided thalamotomy differences were also found in the mean number of perseverative errors and recalled words.

Know how to do better Know-how
Authors: Flämig Benjamin
Published: April 2018

Die Sicherung von Erfahrungswissen stellt in Unternehmen eine große Herausforderung dar. Wissensmanagementsysteme decken mit ihrem Fokus auf explizite Wissensformen aber oft nur einen Bruchteil dessen ab, was „echtes“ Wissensmanagement eigentlich zu organisieren beabsichtigt. Ein System zu etablieren, welches mit beiden Wissensformen umzugehen vermag, war Ziel des dargelegten Projektes. Zugleich soll die häufig geführte Debatte, Bibliothekare seien wohlmöglich die „besseren“ Wissensmanager, um einen praktischen Antwortversuch bereichert werden.
The Dutch Approach to Achieving Open Access
Authors: Heijne Maria A. M. , van Wezenbeek Wilma J. S. M.
Published: April 2018

In this paper, the authors – both of whom are library directors and involved in the contract negotiations with the bigger scientific publishers – present the conditions that formed the Dutch approach in these negotiations. A combination of clear political support, a powerful delegation, a unique bargaining model and fidelity to their principles geared the Dutch to their success in achieving open access. The authors put these joint license and open access negotiations in the perspective of open science and show that they are part of the transition towards open access.

Serum sTREM-1, PCT, CRP, Lac as biomarkers for death risk within 28 days in patients with severe sepsis
Authors: Zhang Lefeng , Zhang Xiaohong
Published: April 2018

This study was undertaken to evaluate the clinical efficacy of serum soluble triggering receptors expressed by myeloid cell-1 (sTREM-1), procalcitonin (PCT), C-reactive protein (CRP) and lactic acid (Lac) as biomarkers for death risk within 28 days in patients with severe sepsis. Fifty-one cases of severe sepsis from the department of ICU in Lishui People’s Hospital from May 2013 to February 2017 were retrospectively analyzed. These cases were divided into survival (n=39) and death (n=12) groups based on the outcome within 28 days of treatment. Serum levels of sTREM-1, PCT, CRP and Lac were measured on the day of admission and compared between the survival and death groups. And the death prediction value within 28 days were evaluated according to serum sTREM-1, PCT, CRP and Lac. The serum level of TREM-1 and Lac were 128.70±46.10 pg/mL, 7.02±1.56 mmol/L for the death group and 83.69±26.57 pg/mL 4.44±0.45 mmol/L for survival group. The serum levels of sTREM-1 and Lac in death group were significantly higher than those of survival group (p<0.05). However, the serum PCT and CRP between the survival and death group were not statistically different (p>0.05). The death prediction sensitivity, specificity and AUC within 28 days were high for serum sTREM-1 (75.00%, 77.78%, 0.79) and APACHEII (74.89%, 84.62%, 0.84). However, the prediction value of serum level PCT, CRP and Lac were relatively low. A significant positive correlation was found between serum sTREM-1 and APACHEII score rpearson =0.54, (p<0.001). However, no such correlation was observed between serum CRP, Lac and APACHEII scores (p>0.05).

Conclusion

Serum sTREM-1 was significantly elevated in sepsis patients who died within 28 days of admission, suggesting that this test could be a potential biomarker for severe sepsis patients, and also be used for prognostic evaluation.
Efficacy of Danhong injection on serum concentration of TNF-α, IL-6 and NF-κB in rats with intracerebral hemorrhage
Authors: Peng Chen , Duan Shibo , Gang Lou
Published: April 2018

Objective

To investigate the efficacy of Danhong injection on the serum concentration of tumor necrosis factor alpha (TNF-α), interleukin 6 (IL-6) and nuclear factor kappa-light-chain-enhancer of activated B (NF-κB) in rats with intracerebral hemorrhage (ICH) and evaluate its therapeutic effects on inflammation and cerebral edema.

Methods

Sixty male Wistar rats were randomly divided into control, model and Danhong groups with 25 rats in each group. Intracerebral injection of autologous arterial blood was performed on model and Danhong groups in order to establish intracerebral hemorrhage model. Rats in the control group were given the same operation procedure without blood injection. After successfully establishing the intracerebral hemorrhage model, the rats were given Danhong (2ml/kg/d) through intraperitoneal injection. Rats in the control and model groups were given the same amount of normal saline respectively. The brain water content (BWC) and serum level of TNF-α, IL-6 and NF-κB were measured in all groups at the time points of day 1, 3, 5, 7 and 9.

Results

The neurological deficit score (NDS) were not statistical different in days 1, 3 and 5 between the model and Danhong group (P>0.05); However, on day 7 and 9 after modeling, the NDS in the Danhong group was significant lower than that of the Model group (P<0.05). The brain water content in the model and Danhong groups were significantly elevated compared to control group (P<0.05). The brain water content was significant elevated after modeling in the model and Danhong groups on day 3 and gradually decreased over the next 6 days.

The brain water content was significantly higher in the model group for days 3 to 9 compared to the Danhong group (P<0.05). Compared to the model group, the serum NF-κb was significantly lower in the Danhong group for the time point of day 3 and 5 (P<0.05); However, compared to the model group, the serum TNF-α and IL-6 levels in the Danhong group were significantly lower for each time point (P<0.05). Conclusion Danhong injection can reduce cerebral edema in rats with cerebral hemorrhage, and protect the brain nerve function. These effects may be related to its function of regulating serum TNF-α, NF-κB and IL-6 expression.
Simulation of personalised haemodynamics by various mounting positions of a prosthetic valve using computational fluid dynamics
Authors: Bongert Markus , Geller Marius , Pennekamp Werner , Nicolas Volkmar
Published: April 2018

Diseases of the cardiovascular system account for nearly 42% of all deaths in the European Union. In Germany, approximately 12,000 patients receive surgical replacement of the aortic valve due to heart valve disease alone each year. A three-dimensional (3D) numerical model based on patient-specific anatomy derived from four-dimensional (4D) magnetic resonance imaging (MRI) data was developed to investigate preoperatively the flow-induced impact of mounting positions of aortic prosthetic valves to select the best orientation for individual patients. Systematic steady-state analysis of blood flow for different rotational mounting positions of the valve is only possible using a virtual patient model. A maximum velocity of 1 m/s was used as an inlet boundary condition, because the opening angle of the valve is at its largest at this velocity. For a comparative serial examination, it is important to define the standardised general requirements to avoid impacts other than the rotated implantation of the prosthetic aortic valve. In this study, a uniform velocity profile at the inlet for the inflow of the aortic valve and the real aortic anatomy were chosen for all simulations. An iterative process, with the weighted parameters flow resistance (1), shear stress (2) and velocity (3), was necessary to determine the best rotated orientation. Blood flow was optimal at a 45° rotation from the standard implantation orientation, which will offer a supply to the coronary arteries.
Recent planning approaches and mobility concepts for home health care services in Austria – A review
Authors: Hirsch Patrick
Published: April 2018

Home health care (HHC) services are faced with a rising demand in Austria. This is due to an increased life expectancy, changing family structures, and the trend to grow old at home. The percentage of their working time that is spent by the HHC staff for travelling from one client to the next one reaches 30% and even more in some rural areas. Changing the assignment of HHC staff to clients and the sequence of visits can lead to major reductions in the travel distances, and therefore, to more sustainable solutions. The aim of this paper is to provide a comprehensive overview on the logistical planning of HHC services in Austria. In order to meet the future requirements, it is important to analyze different mobility concepts for the HHC staff and to provide tailored solution approaches for routing and scheduling. The reader learns about the current HHC situation in Austria, the logistical requirements for planning these services, possible mobility concepts for the HHC staff, and potential threats for HHC operations. The developed solution methods are presented in brief and the main findings are highlighted and discussed. The paper concludes with an outlook on potential future research paths in HHC routing and scheduling.
Comparison of organic and conventional crop yields in Austria
Authors: Brückler Martin , Resl Thomas , Reindl Andreas
Published: April 2018

Organic farming represents an integral part of agriculture in Austria. The share of organic holdings and the share of area being organically farmed are already high relative to other countries within the European Union. So far, analyses of the organic sector have mainly focused on the economic output and the utilised area; less is known about absolute crop yields per hectare and the gap between organic and conventional crop yields. Given their relevance for profitability calculations and production strategies, such data is of major interest for farmers, advisors, and decision-makers. To address this lack of knowledge, we combine the Austrian farm accountancy data and Integrated Administration and Control System data for Austria. This paper presents a statistical analysis of organic crop yield data for the national Austrian territory as well as for regional categories and covers the period from 2003–2016. The results show a significant difference in crop yields: i) between organic and conventional farming systems; ii) between regional categories in Austria. Organic cereals achieve 35% lower average crop yields than conventional systems, yields for organic root and tuber crops were 27–49% lower. Yield gaps of oilseed and protein crops vary widely between respective crop species.
Eye-tracking test design influences the relationship between gazing behaviour and evaluation decision

Recent research has revealed a correlation between consumer gazing behaviour and decision-making in eye-tracking tests, which suggested a predictability decision-making from gazing behaviour. Since the eye-tracking test design has been reported to have an effect on gazing behaviour, the objective of this work is therefore to study systematically whether the test design influences the relationship between choice and gazing. Using a Tobii-T60 Eye Tracker, 100 persons participated in eye-tracking tests working on food images. Two design factors were tested: 1) Type of evaluation (maximum choice,minimum choice,ranking,and rating); 2) Question content (deliciousness,healthiness,prices,and familiarity). The results showed that the correlation between decision-making and gazing behaviour is influenced by bothType of evaluationandQuestion content. Only in the choice tests, a significant correlation between gazing behaviour and consumer decision-making was found. No correlation was found in the question content group Prices, but a very strong correlation existed in the three other question content groups. The results are discussed considering the relationship between visual attention and cognitive processes in decision-making.
