Published: November 2017

Three new zinc complexes with monoamine–guanidine hybridligands have been prepared, characterized by X-ray crystallography and NMR spectroscopy, and tested in the solvent-free ring-opening polymerization of rac-lactide. Initially the ligands were synthesized from camphoric acid to obtain TMGca and DMEGca and then reacted with zinc(II) halides to form zinc complexes. All complexes have a distorted tetrahedral coordination. They were utilized as catalysts in the solvent-free polymerization of technical rac-lactide at 150 °C. Colorless polylactide (PLA) can be produced and after 2 h conversion up to 60% was reached. Furthermore, one zinc chlorido complex was tested with different qualities of lactide (technical and recrystallized) and with/without the addition of benzyl alcohol as a co-initiator. The kinetics were monitored by in situ FT-IR or 1H NMR spectroscopy. All kinetic measurements show first-order behavior with respect to lactide. The influence of the chiral complexes on the stereocontrol of PLA was examined. Moreover, with MALDI-ToF measurements the end-group of the obtained polymer was determined. DFT and NBO calculations give further insight into the coordination properties. All in all, these systems are robust against impurities and water in the lactide monomer and show great catalytic activity in the ROP of lactide.
Study of Structure and Permeability Relationship of Flavonoids in Caco-2 Cells

Published: November 2017

Flavonoids exhibit a broad range of biological activities. However, poor absorption of some flavonoids is a major limitation for use of flavonoids as nutraceuticals. To investigate the structure requirements for flavonoids intestinal absorption, transepithelial transport and cellular accumulation (CA) of 30 flavonoids were determined using the Caco-2 cell monolayer. The bilateral permeation of five types of flavonoids followed the order: flavanones ≥ isoflavones > flavones ≥ chalcones > flavonols. The concentration of flavonoids accumulated in cells did not correlate with cell penetration since the correlation coefficient between the apparent permeability coefficient (Papp) and their corresponding CA was poor (R2 < 0.3). Most flavonoids exhibited a ratio of 0.8–1.5 for Papp A to B/Papp B to A, suggesting passive diffusion pathways. However, luteolin, morin and taxifolin may involve the efflux mechanisms. The quantitative structure-permeability relationship (QSPR) study demonstrated that the intestinal absorption of flavonoids can be related to atomic charges on carbon 3′ (QC3′), molecule surface area (SlogP_V3), balance between the center of mass and position of hydrophobic region (vsurf_ID1) and solvation energy of flavonoids (E_sol). These results provide useful information for initially screening of flavonoids with high intestinal absorption.
Effects of Omega-3 Long Chain Polyunsaturated Fatty Acid Supplementation on Cardiovascular Mortality: The Importance of the Dose of DHA
Authors: Meyer Barbara , Groot Renate
Published: November 2017

Recent evidence on the relationship between omega-3 long chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation and cardiovascular health suggests that n-3 LCPUFA may no longer be efficacious. This review summarises the randomised controlled trials (RCTs) that assess the effect of n-3 LCPUFA supplementation on cardiovascular mortality. It appears that in the RCTs that showed no effect of n-3 LCPUFA on cardiovascular mortality, the dose of n-3 LCPUFA (in particular docosahexaenoic acid (DHA)) and hence the n-3 LCPUFA status, may not have been sufficiently high to demonstrate the efficacy, and/or the baseline n-3 LCPUFA status was already too high. The intention-to-treat analysis (ITT) is the gold standard for analysing RCTs and ITT is used for drug intervention trials where exposure to the drug versus no drug exposure provides two clearly distinct groups to determine the efficacy of the drug being studied. This differs in nutrition trials as often the nutrient of interest being studied is already being consumed by both groups (placebo and active) and therefore a true placebo group with absolutely no intake of the nutrient being studied is highly unlikely. Therefore, in n-3 LCPUFA supplementation trials, as there is no clear distinction between the two groups (placebo and n-3 LCPUFA), a per-protocol analysis (comparison of groups that includes only those participants that fully completed the original intervention allocation) should be conducted in addition to ITT analysis. Furthermore, blood analysis pre- and post-supplementation should be conducted to ensure that: (1) that the baseline n-3 status is not too high, in order to alleviate a potential ceiling effect; and (2) that the dose is high enough and hence the increase in omega-3 status will be high enough in order to assess the efficacy of n-3 LCPUFA supplementation.
How Much Environment Do Humans Need? Evidence from an Integrated Online User Application Linking Natural Resource Use and Subjective Well-Being in Germany
Authors: Buhl Johannes , Liedtke Christa , Bienge Katrin
Published: November 2017

We present the results of a regression analysis of a large-scale integrated user online application that surveys natural resource use and subjective well-being in Germany. We analyse more than 44,000 users who provided information on their natural resource consumption (material footprint) as well as their personal socio-economic and socio-psychological characteristics. We determine an average material footprint of 26 tonnes per person per year. In addition, we endeavour to determine how much environment humans need by regressing natural resource use as well as relevant socio-economic and socio-psychological features on subjective well-being. We establish a slightly negative correlation between subjective well-being and material footprints. A higher material footprint is associated with lower subjective well-being. We conclude that consumer policies seeking to promote sustainable behaviour should highlight the fact that a lower material footprint may result in greater subjective well-being.
GelSight: High-Resolution Robot Tactile Sensors for Estimating Geometry and Force
Authors: Yuan Wenzhen , Dong Siyuan , Adelson Edward
Published: November 2017

Tactile sensing is an important perception mode for robots, but the existing tactile technologies have multiple limitations. What kind of tactile information robots need, and how to use the information, remain open questions. We believe a soft sensor surface and high-resolution sensing of geometry should be important components of a competent tactile sensor. In this paper, we discuss the development of a vision-based optical tactile sensor, GelSight. Unlike the traditional tactile sensors which measure contact force, GelSight basically measures geometry, with very high spatial resolution. The sensor has a contact surface of soft elastomer, and it directly measures its deformation, both vertical and lateral, which corresponds to the exact object shape and the tension on the contact surface. The contact force, and slip can be inferred from the sensor’s deformation as well. Particularly, we focus on the hardware and software that support GelSight’s application on robot hands. This paper reviews the development of GelSight, with the emphasis in the sensing principle and sensor design. We introduce the design of the sensor’s optical system, the algorithm for shape, force and slip measurement, and the hardware designs and fabrication of different sensor versions. We also show the experimental evaluation on the GelSight’s performance on geometry and force measurement. With the high-resolution measurement of shape and contact force, the sensor has successfully assisted multiple robotic tasks, including material perception or recognition and in-hand localization for robot manipulation.
Health Diagnosis of Major Transportation Infrastructures in Shanghai Metropolis Using High-Resolution Persistent Scatterer Interferometry
Authors: Qin Xiaoqiong , Yang Mengshi , Zhang Lu , Yang Tianliang , Liao Mingsheng
Published: November 2017

Since the Persistent Scatterer Synthetic Aperture Radar (SAR) Interferometry (PSI) technology allows the detection of ground subsidence with millimeter accuracy, it is becoming one of the most powerful and economical means for health diagnosis of major transportation infrastructures. However, structures of different types may suffer from various levels of localized subsidence due to the different structural characteristics and subsidence mechanisms. Moreover, in the complex urban scenery, some segments of these infrastructures may be sheltered by surrounding buildings in SAR images, obscuring the desirable signals. Therefore, the subsidence characteristics on different types of structures should be discussed separately and the accuracy of persistent scatterers (PSs) should be optimized. In this study, the PSI-based subsidence mapping over the entire transportation network of Shanghai (more than 10,000 km) is illustrated, achieving the city-wide monitoring specifically along the elevated roads, ground highways and underground subways. The precise geolocation and structural characteristics of infrastructures were combined to effectively guide more accurate identification and separation of PSs along the structures. The experimental results from two neighboring TerraSAR-X stacks from 2013 to 2016 were integrated by joint estimating the measurements in the overlapping area, performing large-scale subsidence mapping and were validated by leveling data, showing highly consistent in terms of subsidence velocities and time-series displacements. Spatial-temporal subsidence patterns on each type of infrastructures are strongly dependent on the operational durations and structural characteristics, as well as the variation of the foundation soil layers.

Published: November 2017

In this paper, we report on a confocal thermoreflectance imaging system that can examine the thermal characteristics of microelectronic devices by penetrating the backside of a device through the substrate. In this system, the local reflectivity variations due to heat generation in the device are measured point by point by a laser scanning confocal microscope capable of eliminating out-of-focus reflections and the thermoreflectance is extracted via Fourier-domain signal processing. In comparison to the conventional widefield thermoreflectance microscope, the proposed laser scanning confocal thermoreflectance microscope improves the thermoreflectance sensitivity by ~23 times and the spatial resolution by ~25% in backside thermoreflectance measurements.
Tensions in Aspirational CSR Communication—A Longitudinal Investigation of CSR Reporting
Authors: Koep Lisa
Published: November 2017

A recent emergence of academic discourse within organisation and management scholarship is encouraging organisations to embrace the performative power of aspirational talk within corporate social responsibility (CSR) communication. However, there has been no empirical study to date to investigate the appropriateness of such encouragement. This paper analyses CSR reporting and underlying sensemaking processes to trace how far this academic departure from the dominant discourse of verification and standardisation is reflected and accepted within this practice. The process-focused, longitudinal study is based on a discursive analysis of Nestlé CSR reports, revealing the struggles between forward and backward facing statements, and tracing the discursive management of tensions between talk and action over a period between 2002 and 2016. The discursive analysis is complemented with findings from seven in-depth interviews with Nestlé senior managers and external non-governmental organisation (NGO) stakeholders to provide insights into the underlying organisational sensemaking. Three tension management phases are detected in the reporting shifting from ignoring aspiration to allowing for a dialectic interplay between aspiration and performance. The interview findings support the detection of the three phases, highlight the dialectic interplay between retrospective and prospective sensemaking as part of the iterative reporting, and underscore the importance of stakeholder involvement in the process.
Green Marketing as the Source of the Competitive Advantage of the Business

Published: November 2017

In this work we focused on summarizing the principles of green marketing and the concepts related to it. The aim of this contribution was to prove the relationship between the implementation of green marketing principles and sustainable competitive company position on the market. In order to prove the relationship between the implementation of green marketing principles and the competitive market position of companies, we used a multiple regression method to reveal the relationship, despite many variables. This was preceded by a factor analysis that helped us to select the main factors of influence. In order to meet this goal, we have drawn from the surveys conducted by PwC (Bratislava, Slovakia), the Automobile Industry Association and the Slovak Automobile Institute to identify key factors and future expected development in the auto industry supplier segment and our marketing research, conducted from December 2015 to February 2016. Based on the results of marketing surveys, research responses and the study of available resources, we concluded that there is no comprehensive green marketing implementation model linking environmental consumer behavior with a link to the company’s marketing strategy. The contribution could help the Automotive Industry Union to present requirements to the government and help create incentives for the alternative vehicle market, and our findings could be incorporated into the creation of companies’ strategy.

Published: November 2017

Flexibility of manufacturing systems is an essential factor in maintaining the competitiveness of industrial production. Flexibility can be defined in several ways and according to several factors, but in order to obtain adequate results in implementing a flexible manufacturing system able to compete on the market, a high level of autonomy (free of human intervention) of the manufacturing system must be achieved. There are many factors that can disturb the production process and reduce the autonomy of the system, because of the need of human intervention to overcome these disturbances. One of these factors is tool wear. The aim of this paper is to present an experimental study on the possibility to determine the state of tool wear in a flexible manufacturing cell environment, using image acquisition and processing methods.

Published: November 2017

Coronaviruses are closely monitored in the context of emerging diseases and, as illustrated with Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) and Middle East Respiratory Syndrome-coronavirus (MERS-CoV), are known to cross the species barrier and eventually to move from wildlife to humans. Knowledge of the diversity of coronaviruses in wildlife is therefore essential to better understand and prevent emergence events. This study explored the presence of coronaviruses in four wild mammal orders in France: Bats, rodents, lagomorphs, and hedgehogs. Betacoronavirus and Alphacoronavirus genera were identified. The results obtained suggest the circulation of potentially evolving virus strains, with the potential to cross the species barrier.
Delineating the Drainage Structure and Sources of Groundwater Flux for Lake Basaka, Central Rift Valley Region of Ethiopia
Authors: Dinka Megersa
Published: November 2017

As opposed to most of the other closed basin type rift valley lakes in Ethiopia, Lake Basaka is found to be expanding at an alarming rate. Different studies indicated that the expansion of the lake is challenging the socio-economics and environment of the region significantly. This study result and previous reports indicated that the lake’s expansion is mostly due to the increased groundwater (GW) flux to the lake. GW flux accounts for about 56% of the total inflow in recent periods (post 2000) and is found to be the dominant factor for the hydrodynamics and existence of the lake. The analysis of the drainage network for the area indicates the existence of a huge recharge area on the western and upstream side of the catchment. This catchment has no surface outlet; hence most of the incoming surface runoff recharges the GW system. The recharge area is the main source of GW flux to the lake. In addition to this, the likely sources/causes of GW flux to the lake could be: (i) an increase of GW recharge following the establishment of irrigation schemes in the region; (ii) subsurface inflow from far away due to rift system influence, and (iii) lake neotectonism. Overall, the lake’s expansion has damaging effect to the region, owing to its poor water quality; hence the identification of the real causes of GW flux and mitigation measures are very important for sustainable lake management. Therefore a comprehensive and detailed investigation of the parameters related to GW flux and the interaction of the lake with the GW system of the area is highly recommended.

A main goal of NASA’s Kepler Mission is to establish the frequency of potentially habitable Earth-size planets (

). Relatively few such candidates identified by the mission can be confirmed to be rocky via dynamical measurement of their mass. Here we report an effort to validate 18 of them statistically using the BLENDER technique, by showing that the likelihood they are true planets is far greater than that of a false positive. Our analysis incorporates follow-up observations including high-resolution optical and near-infrared spectroscopy, high-resolution imaging, and information from the analysis of the flux centroids of the Kepler observations themselves. Although many of these candidates have been previously validated by others, the confidence levels reported typically ignore the possibility that the planet may transit a star different from the target along the same line of sight. If that were the case, a planet that appears small enough to be rocky may actually be considerably larger and therefore less interesting from the point of view of habitability. We take this into consideration here and are able to validate 15 of our candidates at a 99.73% (3σ) significance level or higher, and the other three at a slightly lower confidence. We characterize the GKM host stars using available ground-based observations and provide updated parameters for the planets, with sizes between 0.8 and 2.9 R
⊕. Seven of them (KOI-0438.02, 0463.01, 2418.01, 2626.01, 3282.01, 4036.01, and 5856.01) have a better than 50% chance of being smaller than 2 R
⊕ and being in the habitable zone of their host stars.

We study the heating mechanisms and Lyα escape fractions of 35 Lyα blobs (LABs) at z ≈ 3.1 in the SSA22 field. Dust continuum sources have been identified in 11 of the 35 LABs, all with star formation rates (SFRs) above 100 M
⊙ yr−1. Likely radio counterparts are detected in 9 out of 29 investigated LABs. The detection of submillimeter dust emission is more linked to the physical size of the Lyα emission than to the Lyα luminosities of the LABs. A radio excess in the submillimeter/radio-detected LABs is common, hinting at the presence of active galactic nuclei. Most radio sources without X-ray counterparts are located at the centers of the LABs. However, all X-ray counterparts avoid the central regions. This may be explained by absorption due to exceptionally large column densities along the line-of-sight or by LAB morphologies, which are highly orientation dependent. The median Lyα escape fraction is about 3% among the submillimeter-detected LABs, which is lower than a lower limit of 11% for the submillimeter-undetected LABs. We suspect that the large difference is due to the high dust attenuation supported by the large SFRs, the dense large-scale environment as well as large uncertainties in the extinction corrections required to apply when interpreting optical data.
AT 2017gfo: An Anisotropic and Three-component Kilonova Counterpart of GW170817
Authors: Perego Albino , Radice David , Bernuzzi Sebastiano
Published: November 2017

The detection of a kilo/macronova electromagnetic counterpart (AT 2017gfo) of the first gravitational-wave signal compatible with the merger of two neutron stars (GW170817) has confirmed the occurrence of r-process nucleosynthesis in this kind of event. The blue and red components of AT 2017gfo have been interpreted as the signature of multi-component ejecta in the merger dynamics. However, the explanation of AT 2017gfo in terms of the properties of the ejecta and of the ejection mechanisms is still incomplete. In this work, we analyze AT 2017gfo with a new semi-analytic model of kilo/macronova inferred from general-relativistic simulations of the merger and long-term numerical models of the merger aftermath. The model accounts for the anisotropic emission from the three known mass ejecta components: dynamic, winds, and secular outflows from the disk. The early multi-band light curves of AT 2017gfo can only be explained by the presence of a relatively low-opacity component of the ejecta at high latitudes. This points to the key role of weak interactions in setting the ejecta properties and determining the nucleosynthetic yields. Our model also constrains the total ejected mass associated to AT 2017gfo to be between 0.042 and 0.077

Published: November 2017

We present observations of the interstellar interloper 1I/2017 U1 (’Oumuamua) taken during its 2017 October flyby of Earth. The optical colors B – V = 0.70 ± 0.06, V – R = 0.45 ± 0.05, overlap those of the D-type Jovian Trojan asteroids and are incompatible with the ultrared objects that are abundant in the Kuiper Belt. With a mean absolute magnitude H

V
 = 22.95 and assuming a geometric albedo p

V
 = 0.1, we find an average radius of 55 m. No coma is apparent; we deduce a limit to the dust mass production rate of only ∼2 × 10−4 kg s−1, ruling out the existence of exposed ice covering more than a few m2 of the surface. Volatiles in this body, if they exist, must lie beneath an involatile surface mantle ≳0.5 m thick, perhaps a product of prolonged cosmic-ray processing in the interstellar medium. The light curve range is unusually large at ∼2.0 ± 0.2 mag. Interpreted as a rotational light curve the body has axis ratio

:1 and semi-axes ∼230 m × 35 m. A ≳6:1 axis ratio is extreme relative to most small solar system asteroids and suggests that albedo variations may additionally contribute to the variability. The light curve is consistent with a two-peaked period ∼8.26 hr, but the period is non-unique as a result of aliasing in the data. Except for its unusually elongated shape, 1I/2017 U1 is a physically unremarkable, sub-kilometer, slightly red, rotating object from another planetary system. The steady-state population of similar, ∼100 m scale interstellar objects inside the orbit of Neptune is ∼104, each with a residence time of ∼10 years.

Du jeu précoce du bébé au jeu symbolique de l’enfant : une étude dans les crèches
Authors: Saboia Camila , Kupfer Maria Cristina Machado
Published: November 2017

Le jeu a un rôle essentiel dans le processus de construction de la subjectivité du bébé. Nous constatons cependant que l’échange ludique et le jeu ne sont pas suffisamment privilégiés dans les crèches où sont plutôt priorisés les aspects hygiéniques ou soins physiques et cognitifs au détriment des aspects subjectifs du bébé. De façon à rendre compte de l’importance d’un instrument de suivi du jeu précoce dans les crèches, notre étude a porté sur l’évaluation de l’instrument irdi (Indicateur de risque pour le développement infantile) dans la détection et l’accompagnement du jeu précoce du bébé. Pour ce faire, nous avons pu établir une corrélation entre certaines données récoltées par le protocole irdi auprès de bébés âgés de 8 à 12 mois avec les résultats du test projectif mppe (Malette projective de la première enfance) réalisé auprès de ces mêmes enfants à l’âge de 2 ans, ce qui nous a permis de conclure que l’instrument irdi est utile pour détecter et accompagner la mise en place du jeu précoce du bébé.

Les nombreuses divisions qui ont émaillé la XIV e  législature conduisent à s’interroger sur la possible fin de la discipline partisane. L’ampleur de la fronde et la contestation des consignes, y compris au sein du premier parti d’opposition, conduisent à valider cette hypothèse. Le rejet de la discipline partisane semble ainsi définitif, à moins que la nouvelle législature n’en réinvente les codes.

L’hypothèse princeps de Green concernant la psycho­somatique est le clivage de l’ensemble pulsion-objet, par opposition à la régression archaïque du lien sujet objet maintenu dans la psychose.
Penser la psychosomatique avec les concepts d’André Green
Authors: Duparc François
Published: November 2017

Sans être un psychosomaticien avéré, André Green était proche de la psychosomatique française et de P. Marty. Ses points de convergences sont l’affect, pour lutter contre la focalisation sur la parole des freudiens et des lacaniens en France, ainsi que l’hallucination négative du corps et de l’émotion, et la clinique du vide laissé par la mère morte. Sa notion de « vécus irreprésentables » faute d’un objet pour la pulsion le conduit à privilégier la motion pulsionnelle, embryon d’intentionnalité psychosomatique. La forclusion de certains fantasmes originaires peut être déduite de ses idées sur les mouvements pré-psychiques, en lien avec les lignées psychosomatiques de M. Fain.

“Like Hearing From Them in the Past”
Authors: Boltz Liz Owens
Published: November 2017

Historical empathy is a multidimensional construct that involves both the cognitive recognition of the perspectives of others as well as affective engagement with the lived experiences of people in the past. Actively engaging learners with diverse historical perspectives in activities like debate, writing, and role play has been shown to be more effective than traditional instruction in the promotion of historical empathy, but less is known about the effectiveness of videogames in this regard. This case study article examines how historical empathy manifested during play of the videogame Valiant Hearts. The results indicate that certain types of game play may promote particular dimensions of historical empathy better than others, and that some dimensions tend to arise spontaneously while others require (or even resist) prompting.
E-Learning Systems Requirements Elicitation

Published: November 2017

Training and education have evolved far beyond black boards and chalk boxes. The environment of knowledge exchange requires more than simple materials and assessments. This article is an attempt of parsing through the different aspects of e-learning, understanding the real needs, and conducting the right requirements to build the appropriate e-learning system. E-learning systems, unlike the normally developed systems, have variable customers and on-going demands. It is not the easiest task to elicit unambiguous functional and non-functional requirements for such systems. However, a brief exploration of some of the e-learning characteristics may tremendously decrease the difficulty of prioritizing the most important requirements.

Diminutives of bases on a vowel or glide in central southern and south western dialects: a specification

The excellent first part of the Morphological Atlas of the Dutch Dialects (MAND 2005) discusses the formation of diminutives in Dutch dialects, taking diminutives of bases ending on 'vowel, diphtong or glide' as a point of reference, 'after which the diminutive suffix can develop freely and most naturally.' Based on data from central southern and southwestern dialects, this article presents a more precise account, in which bases ending on a monophtong are contrasted with bases ending on diphtongs and glides.
Sensitivity of stomatal conductance to soil moisture: implications for

Abstract. Soil moisture and water stress play a pivotal role in regulating stomatal behaviour of plants; however, in the last decade, the role of water availability was often neglected in atmospheric chemistry modelling studies as well as in integrated risk assessments, despite through stomata plants remove a large amount of atmospheric compounds from the lower troposphere. The main aim of this study is to evaluate the effect of soil water limitation on stomatal conductance and assess the resulting changes in atmospheric chemistry testing various hypotheses of water uptake by plants in the rooting zone; following the main assumption that roots maximize water uptake, i.e. they adsorb water at different soil depths depending on the water availability, we improve the dry deposition scheme within the chemistry transport model CHIMERE. Results highlight how dry deposition significantly declines when soil moisture is used to regulate the stomatal opening, mainly in the semi-arid environments: in particular, over Europe the amount of ozone removed by dry deposition in one year without considering any soil water limitation to stomatal conductance is about 8.5 Tg O3, while using a dynamic layer that ensures plants to maximize the water uptake from soil, we found a reduction of about 10 % in the amount of ozone removed by dry deposition (~ 7.7 Tg O3). Despite dry deposition occurs from top of canopy to ground level, it affects the concentration of gases remaining into the lower atmosphere with a significant impact on ozone concentration (up to 4 ppb) extending from the surface to the upper troposphere (up to 650 hPa). Our results shed light on the importance of improving the parameterizations of processes occurring at plant level (i.e. from the soil to the canopy) as they have significant implications on concentration of gases in the lower troposphere.

Abstract. IODP Expedition 357 utilized seabed drills for the first time in the history of the ocean drilling program, with the aim of collecting intact sequences of shallow mantle core from the Atlantis Massif to examine serpentinization processes and the deep biosphere. This novel drilling approach required the development of a new remote seafloor system for delivering synthetic tracers during drilling to assess for possible sample contamination. Here, we describe this new tracer delivery system, assess the performance of the system during the expedition, provide an overview of the quality of the core samples collected for deep biosphere investigations based on tracer concentrations, and make recommendations for future applications of the system.

Um olho aberto na noite: em torno dos fotogramas de Éric Rondepierre
Authors: Fontes Osvaldo
Published: November 2017

Este artigo ressalta alguns engajamentos da linguagem fotográfica de Éric Rondepierre, artista particularmente concernido pelas metamorfoses da imagem em razão da usura do tempo no dispositivo cinematográfico. Seu trabalho de arquivista e arqueólogo dos fotogramas, essas imagens congeladas dos filmes, tem configurado nos últimos 30 anos uma surpreendente visualidade ancorada no espectral, no híbrido e no descontínuo. Ao narrar a travessia iniciática de um sujeito do olhar pelas materialidades da imagem fílmica, o romance La Nuit Cinéma (2005), ficcionalização de seu fazer artístico, presta-se aqui a balizar um percurso por seus motivos mais significativos: o limite, o desvio, o acaso, o vazio, operadores de uma latência que ajuda a repensar as eficácias do visual e os mecanismos do imaginário em tempos de um contínuo fluxo narrativo.
Correlations between Cotton Characteristics in Greek Multi-environments

Published: November 2017

Correlations of data provided by AFIS and HVI were performed under a multi-location evaluation of cotton fiber characteristics in the Greek environment. Four main cotton-production Greek regions were selected and the five most cultivated commercial upland cotton (Gossypium hirsutum L.) cultivars were used for evaluation of fiber length and short fiber characteristics by AFIS and HVI instruments. Each cultivar was sown in 16 fields and 80 fields in total were used for all cultivars. Both HVI and AFIS gave reliable data concerning fiber length and short fiber estimations. High positive and statistically significant correlations between the two instruments were found indicating the similarity of final measurements. Fiber length estimations can be performed with higher accuracy than short fiber estimations, because CV values were lower for both instruments. HVI and AFIS showed different advantages in estimating fiber length and short fiber characteristics. Measurements of AFIS on fiber length had a smaller range between maximum and minimum values, but HVI showed lower CV% which is more useful for breeders, since it may indicate gene fixation that ensures easier breeding procedure. For short fibers, AFIS also showed a smaller range between maximum and minimum values and HVI showed lower CV%. Graphical comparisons between HVI and AFIS measurements for fiber length and short fibers showed that HVI had a more pattern with lower fluctuations than AFIS.

Safety of the railway transport is extremely important issue, thus it has to be supported by numerous of terms. It is not only the legislation and organization or traffic control but also the proper quality of every devices in the railway infrastructure. The paper deals with safety in the rail industry. Companies and producers of railway equipment have to guarantee the best quality, maintenance and reliability. Safety is also a device directly responsible for protecting e.g. level crossings but also safety in terms of design and construction. . Supervision of products is fulfilled in Poland by e.g. the Office of Railway Transport managing the safety and regulation of rail traffic. The paper presents industry security in terms of product as safety in design and production, in construction, in exploitation. Despite such extensive, multisector and multifaceted organizational, legal and technical safety structures in rail transport it is advisable to conduct further research into the analysis of the possibilities for improved safety. Also authors have assumed that for the improving of railway crossing safety level the support system for the traffic detection can be developed. To increase of the complex crossing safety level the support system has to be independent from current usage control devices, as axle counter block. Thus the paper presents concept of application of vibration wave propagation employing as source if information on train or car detection.
CHANGES IN LAND USE: ILLUSTRATION OF THE IMPACT OF REGIONAL
PROGRAM SUPPORT IN INCREASING THE FORESTED AREA IN PODLASKIE
VOIVODSHIP

Achieving goals of the national reforestation program for 2020 is threatened by its slow implementation despite financial
support provided through the EU rural development programs. This study attempts to examine association between the increase
in the forest cover and they are of agricultural land in Poland between 2010 and 2015 and the indirect association between
the forest cover and regional migration, and residents seeking employment outside agriculture by registering microenterprises
focusing only on Podlaskie Voivodship. The description of the observed developments has been supplemented by calculations of
the Pearson correlation coefficient between the key indicators considered in this study. The calculated correlations coefficients
suggest strong association between the EU funding and the reforested area in three districts surrounding the major cities in the
region. Strong correlations were found between regional migration and the entrepreneurial activity reflected in the number of
registered micro-enterprises in the case of Białystok and Łomża districts, but somewhat weaker associations in the case of Suwałki
district. The transfer of land away from agriculture to reforestation is affected by the local technical infrastructure expansion,
e.g., road construction, and influences the obtained correlation coefficients.

Published: November 2017

‘Repetitions in Reserve’ (RIR) scales in resistance training (RT) are used to control effort but assume people accurately predict performance a priori (i.e. the number of possible repetitions to momentary failure (MF)). This study examined the ability of trainees with different experience levels to predict number of repetitions to MF. One hundred and forty-one participants underwent a full body RT session involving single sets to MF and were asked to predict the number of repetitions they could complete before reaching MF on each exercise. Participants underpredicted the number of repetitions they could perform to MF (Standard error of measurements [95% confidence intervals] for combined sample ranged between 2.64 [2.36–2.99] and 3.38 [3.02–3.83]). There was a tendency towards improved accuracy with greater experience. Ability to predict repetitions to MF is not perfectly accurate among most trainees though may improve with experience. Thus, RIR should be used cautiously in prescription of RT. Trainers and trainees should be aware of this as it may have implications for the attainment of training goals, particularly muscular hypertrophy.
