Ar vag beuzet – Gwerz relatant le naufrage d’un bateau goémonier à Pleumeur-Bodou au xviiie siècle
Authors: Giraudon Daniel
Published: December 2018

Dans le sillage de la querelle du Barzaz-Breiz, on a pu mettre en doute l’authenticité de nos chants populaires, notamment ceux à caractère historique les gwerzioù comme on les nomme. Longtemps transmises de bouche à oreille, parfois même sur plusieurs siècles, certaines d’entre elles ont ainsi eu la bonne fortune de faire carrière dans la tradition orale ce qui n’a pas évidemment été sans incidence sur leur forme et leur contenu, même s’il y a de quoi s’étonner de la fidélité des mémoires populaires dans le passé. Leur originalité a été, entre autres, de préserver la richesse des noms de lieux et de personnes dont elles racontent l’histoire. C’est ce qui permet parfois, en croisant leurs paroles avec des pièces d’archives écrites, de retracer le déroulement des faits qu’elles rapportent et d’en apprécier le degré de véracité.C’est ce que nous avons cherché à faire au sujet d’un naufrage survenu au milieu du xviiie siècle sur les côtes du Trégor en ajoutant quelques lignes sur le rôle du compositeur en ces temps où l’oral l’emportait sur l’écrit dans les milieux populaires.
LETO (Littoral, État, Océan), un dispositif test sur les enquêtes littorales (xviie-xixe siècles)
Authors: Acerra Martine
Published: December 2018

Une petite équipe de chercheurs intéressés par le
phénomène des enquêtes littorales à l’époque moderne a réfléchi à la
construction d’un portail, un Système Informatique Historique qui soit
à la fois une bibliothèque extensive des enquêtes et un faisceau
d’outils nécessaires à leur exploitation. Ce dispositif est présenté
ici et décrit dans le contexte historiographique d’aujourd’hui, avec
ses objectifs, ses modalités et ses tests de faisabilité, ces derniers
faisant l’objet de quatre contributions publiées à la suite de cette
introduction programmatique. La particularité du dispositif LETO
consiste à considérer la continuité séculaire du phénomène de
l’enquête littorale et à s’interroger sur la profondeur de la mémoire
d’État, en convoquant et confrontant une dizaine d’enquêtes dans leurs
modalités de construction et d’exécution, leurs contenus informatifs
et leurs conséquences autant pour l’État qui les commandite que pour
les acteurs littoraux qui les subissent et y réagissent.
De la haine du mari au sacrifice du patrilignage en contexte coutumier
Authors: Viret Jérôme Luther
Published: December 2018

L’affaire dont il est question se déroule en deux
temps. Marie Madeleine de Meherenc, dame de Croisille, est enfermée à
l’hôtel Dieu de Caen en 1747. Elle y séjourne de son plein gré,
peut-être déjà sous la menace d’une lettre de cachet. Son mari a en
effet à lui reprocher une inconduite et même un commerce scandaleux
avec un commis aux aides. Mécontent de constater que son épouse trouve
encore à circuler librement, il obtient des ordres du roi pour la
faire enfermer en un lieu plus sérieux. C’est le début d’une errance,
qui conduit la Dame à Domfront puis à Guingamp. On ne sait presque
rien des 23 années suivantes. À la mort de son mari, survenue en 1770,
elle réapparaît à Villers-Bocage. Elle y cohabite un temps avec son
fils, François Jean Charles de Croisilles et sa bru, avant de les
expulser de sa maison. La suite des évènements convainc le public
qu’elle déteste son fils, qu’elle veut le priver de tous ses biens. En
1778, tandis qu’elle a 66 ans, son fils la fait à nouveau enfermer.
L’affaire, richement documentée, sur un arrière-plan patrimonial, mêle
affects, sentiments conjugaux et filiaux. L’affaire ici exposée
témoigne simultanément d’un phénomène général – la crise du couple et
la remise en question de l’autorité maritale à la fin de l’Ancien
Régime – et d’un phénomène plus spécifiquement normand, qui est la
persistance dans cette province d’un esprit patrilignager ignoré
ailleurs à un tel degré.
Le quartier Anglo ou les contrechamps d’un paysage patrimonial
Authors: Epstein Ariela
Published: December 2018

Cet article s’intéresse à une ancienne enclave ouvrière uruguayenne : avant-garde du développement industriel national durant plus d’un siècle, l’usine Anglo del Uruguay ferme en 1979. Bien plus tard, le site, incluant la zone de production comme la compagny town, est réinvesti pour ses atouts patrimoniaux et touristiques et devient, en 2015, patrimoine mondial de l’humanité de l’Unesco. L’article interroge différents régimes d’historicité, construisant plusieurs communautés d’expériences, à l’œuvre dans le quartier actuel. Son ethnographie amène en effet à « reprendre » l’histoire du quartier, à partir de la dictature militaire qui correspond, juste après la fermeture de l’usine, à l’expulsion de presque tous les habitants du quartier Anglo. La non-écriture de cette partie de l’histoire semble induire, ou maintenir, un « trouble » perceptible chez une partie des habitants, que l’auteur chercher à cerner. Ce qui entre ou n’entre pas dans l’ordre du patrimoine étant délimité par la ligne qui sépare les discours légitimes des autres, les récits du passé cristallisent un ensemble de problématiques politiques qui peinent à se faire entendre comme telles. Posant un regard pragmatique sur le processus de labélisation en cours, il s’agit d’interroger un conflit toujours présent, bien que latent, autour du droit à la ville.
A sense of place ou le devenir familier des paysages industriels en Grande-Bretagne
Authors: Duquerroy Marion
Published: December 2018

Entre utopie et dystopie, le paysage industriel anglais cherche à se réinventer. Longtemps rejeté au profit d’un modèle arcadien, il s’inscrit aujourd’hui, de plus en plus nettement, comme partie prenante du patrimoine national. Cette évolution n’est cependant possible que grâce à des actions politiques et plus particulièrement celles initiées par les régions sinistrées. Fortes de leurs balafres usinières et profitant du renouveau du genre ruiniste en vogue, ces zones, aujourd’hui désindustrialisées, deviennent les terrains d’expérimentation des artistes. En s’intéressant à deux projets artistiques commissionnés par des institutions que sont les deux volets de l’exposition Futureland (1989) et Futureland Now (2003), montrant les clichés de John Kippin et Chris Wainwright, et A Free and Anonymous Monument (2003) de Jane et Louise Wilson, cet article montre l’importance des commandes pour la réévaluation des friches et sites industriels. C’est alors par le prisme de l’esthétique que ces lieux peuvent revivre, raconter leur histoire et en inventer de nouvelles. Cependant, cette esthétisation, parfois excessive, détache, selon certains, ces paysages de leur rôle mémoriel complexe. Ils viendraient ainsi servir l’appétence actuelle du public pour le motif de la ruine et deviendraient le paradis du ruin porn.
La mise en récit(s) de la photographie en France
Authors: Lavie Juliette
Published: December 2018

Quelle histoire de la photographie les photographes ont-ils écrite ? Cet article appréhende cette question à partir de quelques exemples français (Emmanuel Sougez, Daniel Masclet, Marcel Bovis, André Vigneau) qui ont tout autant produit des récits techniques sur la photographie, dont les premiers modèles datent du xixe siècle, que proposé des écrits intégrant les modèles issus de l’histoire de l’art : histoire des artistes, histoire des styles, histoire biologique du photographique pensée en termes d’origine, de croissance, de décadence, de renaissance. Si ces photographes actifs entre les années 1930 et 1970 ont maintenu les vieilles traditions d’écriture qui, pour certaines, remontent à Johann Joachim Winckelmann, ils ont également su s’en émanciper et transmettre leurs regards spécifiques de praticiens à la nouvelle génération composée par Jean-Pierre Sudre, Jean-Claude Gautrand, Claude Nori. Véritable entrée dans les années 1930-1970, ce texte montre que ces acteurs français de l’historiographie ont toujours abordé l’histoire en photographe et non la photographie en historien et que, tout au plus, ils se sont considérés comme des témoins et des fabricateurs de récit(s) qui pouvaient donner à voir, à lire et à entendre l’histoire sous l’angle de ceux qui la fabriquent. Cet article porte en définitive sur un territoire : l’histoire qui reste à conquérir ; un territoire en pleine mutation, où la mémoire compose, avec l’image, les récits de la photographie des photographes.
De l’autoportrait de la « dame en rose » aux calligraphes anonymes
Authors: Guillaume-Pey Cécile
Published: December 2018

En Inde, on assiste au passage à l’art et à la mise en patrimoine de nombreuses formes expressives produites par des groupes tribaux (Adivasi). Cet article porte sur les modalités de production et de réception de diverses formes d’« art tribal » à partir d’enquêtes menées dans trois musées de Bhopal, capitale de l’État du Madhya Pradesh, au centre de l’Inde, qui constitue un haut lieu de déploiement de l’art tribal indien depuis les années 1980. Derrière les formes esthétiques labellisées « art tribal » se profilent un ensemble de pratiques essentiellement visuelles, hétérogènes du point de vue de leur histoire respective et, plus particulièrement, de leur ancrage dans des pratiques villageoises. Si les premiers chercheurs qui se sont intéressés à ces dernières – et qui ont largement contribué à façonner la catégorie d’« art tribal » en contexte indien et à le rendre populaire à l’étranger – ont mis en avant leur association au registre religieux, les formes artistiques qui se déploient dans les musées de Bhopal ces trente dernières années ne s’inscrivent pas toujours en continuité avec des pratiques exécutées en contexte rituel à l’échelle du village. Ces nouveaux genres visuels, créés au musée ou sous l’impulsion de ses représentants, connaissent aujourd’hui des destins contrastés.
An emic science of climate. Reindeer Evenki environmental knowledge and the notion of an “extreme process”
Authors: Lavrillier Alexandra , Gabyshev Semen
Published: December 2018

Cet article, co-écrit par Lavrillier (anthropologue) et Gabyshev (éleveur de rennes et co-chercheur) se base sur leur matériaux de terrain qui documentent et analysent le système complexe de savoirs écologiques. Ayant discuté leur méthodologie d’observatoire transdisciplinaire installé chez une communauté évenk pour le monitoring, avec les éleveurs, des changements climatiques et environnementaux, l’article dévoile certains résultats de cette co-production des savoirs. L’article présente la science émique du climat (ses typologies et concepts) que les Évenks utilisent pour comprendre normes et anomalies, pour observer et prédire les changements et pour s’adapter. Les auteurs développent la notion de « processus extrême » comme étant plus représentative de la manière dont les nomades font face au changement climatique, que « évènement extrême » (utilisée usuellement). Analysant plusieurs cas d’études, ils définissent cette notion comme une accumulation d’anomalies climatiques de différentes origines, et parfois d’autres dysfonctionnements de l’environnement. Quand des facteurs extérieurs (économiques, politiques, industriels) s’ajoutent, cela devient un « processus extrême hybride », qui, lui, questionne sérieusement la résilience de cette société nomade.
An exploration of a Tibetan lama’s study of the Pythagorean theorem in the mid-18th century
Authors: Yongdan Lobsang
Published: December 2018

Bien que les civilisations anciennes comme l'Inde et la Chine aient eu leurs propres façons de mesurer les triangles à angle droit, une méthode particulière attribuée au mathématicien grec Pythagore (570-495 av. J.-C.) fut introduite en Chine au xvie siècle par le jésuite européen Matteo Ricci (1552-1610). Au xviiie siècle, lorsque les Tibétains commencèrent à s'intéresser à l’astronomie, à la géographie et à la médicine européennes, la géométrie euclidienne fut l'une des idées mathématiques apportées au Tibet. Cet article décrit comment le savant tibétain Akya Lobzang Tenpai Gyaltsen (1708-1768) étudia le théorème de Pythagore à Pékin et le diffusa au Tibet, deux siècles avant la date d’introduction de la science européenne au Tibet généralement donnée par les spécialistes.
A Flexible Scheme to Model the Cognitive Influence on Emotions in Autonomous Agents
Authors: Castellanos Sergio , Rodríguez Luis-Felipe
Published: December 2018

Autonomous agents (AAs) are designed to embody the natural intelligence by incorporating cognitive mechanisms that are applied to evaluate stimuli from an emotional perspective. Computational models of emotions (CMEs) implement mechanisms of human information processing in order to provide AAs for a capability to assign emotional values to perceived stimuli and implement emotion-driven behaviors. However, a major challenge in the design of CMEs is how cognitive information is projected from the architecture of AAs. This article presents a cognitive model for CMEs based on appraisal theory aimed at modeling AAs' interactions between cognitive and affective processes. The proposed scheme explains the influence of AAs' cognition on emotions by fuzzy membership functions associated to appraisal dimensions. The computational simulation is designed in the context of an integrative framework to facilitate the development of CMEs, which are capable of interacting with cognitive components of AAs. This article presents a case study and experiment that demonstrate the functionality of the proposed models.

Authors: Feng Lixiao , Chen Guorong , Peng Jun
Published: December 2018

Due to high temperature, high pressure, high corrosion, and many other factors, the hazardous chemical device is facing more severe security challenges than other industries. Now, the monitoring methods have been very mature, which play a basic monitoring role, not a predictive fault diagnosis. In this article, the hazardous chemical device's status data will be collected from the existing industrial monitoring network, the real-time data will be preprocessed and then stored in a database, and the data will be imported to the real-time data into the ontology cognitive model; the data will be performed by big data processing and automatic reasoning so that real-time status of hazardous chemical device and the warning of security risks predict are easily obtained at any time. The model is proposed to solve the problem of knowledge representation and reasoning of the hazardous chemical device based on ontology. The model is analyzed and implemented in Protégé software.
E-Government Services Adoption
Authors: Mensah Isaac Kofi
Published: December 2018

This research article explores the important elements of trust and transparency to the adoption of e-government services. The Technology Acceptance Model was used as the theoretical framework. The data capture and analyses were conducted with SPSS. The results indicate that trust in the internet was a significant predictor of both the intention to use and perceived ease of use (PEOU), but was not significant in predicting perceived usefulness (PU) and the actual use (AU) of e-government services. Trust in the government (TG) was also not significant in determining both the intention to use and PEOU of e-government services. Rather TG had a significant impact on PU and the actual use (AU) of e-government services. Furthermore, perceived transparency was a significant predictor of PU, IU, and AU of e-government services. The implications of these findings on the implementation of e-government are thoroughly discussed.

Donation Model Development Based on the Methodologies of Blockchain
Authors: Fu Meng-Hsuan
Published: December 2018

In order to solve the problems occurring in the current donation systems, the methodologies of blockchain include decentralized data storage, transaction hash, digital signature, blocks connection within the chain are adopted to the donation model, called blockchain donation model (BDM). In BDM, all donation transactions are recorded in detail and stored permanently; they are not allowed to change, modify, or delete. In addition, donors could indicate the specific groups for donating directly because of the peer-to-peer transmission method. All the information is sealed through the secure mechanism; only donors and donees could decrypt it with their own keys. BDM records transaction flows starting from receiving to spending the donation in detail. BDM is not only a place for listing details of donations but also a secured transaction storage. The blocks are connected together with a strong chain which is maintained by all nodes in the blockchain network. Thus, BDM is a platform dealing with the donation issue under a well secure mechanism, no intermediaries, and a permanent storage.

Location Tracking Prediction of Network Users Based on Online Learning Method With Python
Authors: Xu Xin , Lu Hui
Published: December 2018

Aiming at the problem that the precision and recall rate of traditional prediction methods are low and its low prediction efficiency, a Python-based trajectory tracking prediction method of online learning network user location is proposed. First, troubleshooting terminal programs of online learning network user by programming in Python (computer programming language) structure, the location trajectory data of online learning network user is spatially processed. In this way, features of time-related, spatial correlation, social relationship correlation, and user preference characteristics are extracted respectively to realize feature normalization processing. Second, on this basis, the cosine similarity is used to calculate the similarity of user behavior trajectory. According to K-MEANS (hard clustering algorithm), the time dimension is considered. Finally, the clustering result of users' behavior trajectory based on the sign-in data is compared with a preset threshold to predict the online user location trajectory. The experimental results show that the proposed method normalizes the user's trajectory, combines the time segment, and compares it with the preset threshold, which does not only improve the prediction efficiency but also obtains higher and more feasible precision and recall rate.

Adaptive BPEL Service Compositions via Variability Management
Authors: Sun Chang-ai , Wang Zhen , Wang Ke , Xue Tieheng , Aiello Marco
Published: December 2018

Service-Oriented Architectures are a popular development paradigm to enable distributed applications constructed from independent web services. When coordinated, web services are an infrastructure to fulfill dynamic and vertical integration of business. They may face frequent changes of both requirements and execution environments. Static and predefined service compositions using business process execution language (BPEL) are not able to cater for such rapid and unpredictable context shifts. The authors propose a variability management-based adaptive and configurable service composition approach that treats changes as first-class citizens and consists of identifying, expressing, realizing, and managing changes of service compositions. The proposed approach is realized with a language called VxBPEL to support variability in service compositions and a platform for design, execution, analysis, and maintenance of VxBPEL-based service compositions. Four case studies validate the feasibility of the proposed approach while exhibiting good performance of the supporting platform.

Heat treatment is very important factor for improving material strength. In our previous work, we combined a furnace heating and induction heating to develop a new method (furnace-induction heating, FIH). We observed the microstructure in JIS SUJ2 bearing steel and found that FIH process refined the prior austenite grains. In this work, we further investigated the relation between hardness distribution and retained austenite in furnace-induction heated JIS SUJ2 steel.
Casting of Aluminum Alloy Rod by a Single Wheel with V-Groove
Authors: Haga Toshio , Miyake Taisei
Published: December 2018

Casting of a convex rod from 5182 aluminum alloy was attempted using a single wheel caster with a V-shape groove. The diameter of the mild steel wheel was 600 mm, the angle of the vortex was 90 degrees, and the width of the groove was 20 mm. Important factors to cast a rod with a convex shape are the speed of the molten metal ejected from a hole-nozzle and the collapse angle between the molten metal stream and the wheel. Important factors that affected the cross sectional shape of cast-bar were the speed of molten metal ejected from the hole-nozzle and the collapse angle of the molten metal against the wheel. A collapse angle close to 90° was better than an angle less than 90°. Casting speeds of 5 m/min and 15 m/min were employed, which resulted in convex cross sectional rod areas of 30 mm2 to 190 mm2.

Published: December 2018

Fish processing industry has led to large amounts of waste every year around the world. However, waste from the fish bone contains valuable compound such as hydroxyapatite (HAp). Fish bones are natural resources and have an attractive added value which contains HAp that can potentially be used as hybrid sunscreen. Therefore, Fringescale sardinella (Valenciennes, 1847) bones have been discovered and HAp was synthesized to be applied in cosmeceuticals applications. The properties of HAp from Fringescale sardinella bones have been characterized with Fourier Transform Infrared Ray (FTIR) and Cytotoxicity test. The emulsions have been formulated and tested under Ultraviolet Visible (UV-Vis) Spectroscopy. Results had indicated that fish bones doped with FeCl2 shows higher tendency as sunscreen compared to MnCl2 and unmodified bones. Thus, the utilization of waste from fish bones will not only adding value to the by-products, but also help in reducing pollution to the environment and preventing from global warming. Hence, formulation on emulsion synthesized from fish bone is designed as a new hybrid innovation in cosmeceutical products and boost up the efficiency of skin prevention from UV radiation.

Authors: Sosiati Harini , Nur Fatihah Wahyu , Yusmaniar  , Nur Rahman M. Budi
Published: December 2018

The spinning solution of blended hybrid poly (vinyl alcohol) (PVA)_Aloe Vera (AV) with various concentrations (0%, 3%, 10% and 15%) of chitosan nanoemulsion (CSNe) were electrospun under optimized conditions of high DC voltage 15 kV, distance of spinneret tip to collector plate 16.5 mm and spinneret diameter 0.8 mm. This work aims to manufacture the blended hybrid PVA_AV/CSNe nanofibrous membranes and characterize the solution and fiber properties, and tensile properties of the nanofibrous membranes by varying CSNe concentrations. Scanning electron microscopy (SEM) results revealed that beads-free fiber structure featured in all electrospun membranes with relatively homogeneous fiber size distribution. An increase of CSNe concentration from 0% to 15% reduces the average fiber size from 366 nm to 180 nm and increase tensile strength from 2,52  0.54 MPa to 6.18  0.15 MPa and tensile modulus from 7.5  1.06 MPa to 21.9  9.88 MPa of the membranes, respectively. The tensile strength of the present blended hybrid PVA_AV/CSNE nanofibrous membranes with 15% CSNe concentration and tensile modulus of that with all CSNe concentrations are included in the range of the natural skin properties: i.e. (5.00 – 30.00 MPa) and (4.6 – 20.0 MPa) for tensile strength and modulus, respectively. Such data suggest the potential use of the membranes as wound dressing material in the near future.

Authors: Haga Toshio , Okamura Kentaro , Warari Hisaki , Nishida Shinichi
Published: December 2018

The effect of the base strip temperature on the bonding between base strip and overlay strips in a three-layer clad strip cast by a vertical-type tandem twin roll caster was investigated. The base strip was 3003 aluminum alloy and the overlay strip was 4045 aluminum alloy. The bonding was investigated for base strip temperatures ranging from 200 °C to 550 °C. The bonding condition was investigated by cold-rolling, bending-to-failure test and tensile shear test. The shear stress increased with the base strip temperature. Sound bonding was achieved at base strip temperatures higher than 450 °C. The results of this study indicated that the second caster is not required to be set below the first roll caster.

Authors: Saijaioup Narudon , Kajitvitchyanukul Puangrat , Watcharenwong Apichon
Published: December 2018

Titanium dioxide (TiO2) nanotubes with a highly ordered structure were grown by a self-organized anodization process. The photodeposition process was used to improve the visible light response of titanium dioxide (TiO2) nanotubes. The irradiation was carried out with 500 W halogen lamp for 1, 5, 15, 30 and 60 min in the mixed ethanol solution of antimony trisulfide (Sb2S3). The obtained samples were annealed at 250 °C for 30 min. The morphology of the fabricated sample was characterized by a field emission scanning electron microscope (FE-SEM). The phase of samples was determined by X- ray diffractometer (XRD). The weight percentages of a component in the sample were measured by X-ray fluorescence spectrometry (XRF). UV-Vis diffuse reflectance spectra (DRS) of the samples were recorded. All titanium dioxide (TiO2) nanotube samples prepared by anodization process were anatase phase. All composite titanium dioxide (TiO2) nanotube /Sb2S3samples were a crystalline phase. The percentage of Sb and S increase with increasing of photodeposition’s time. The increasing photodeposition of antimony trisulfide (Sb2S3) on titanium (TiO2) nanotubes from 1 to 60 min lead to increasing of photoabsorption property of the material in the visible region.

Induction of the BIM Short Splice Variant Sensitizes Proliferating NK Cells to IL-15 Withdrawal
Authors: Jacobs Benedikt , Pfefferle Aline , Clement Dennis , Berg-Larsen Axel , Saetersmoen Michelle L. , Lorenz Susanne , Wiiger Merete Thune , Goodridge Jodie P. , Malmberg Karl-Johan
Published: December 2018

Adoptive transfer of allogeneic NK cells holds great promise for cancer immunotherapy. There is a variety of protocols to expand NK cells in vitro, most of which are based on stimulation with cytokines alone or in combination with feeder cells. Although IL-15 is essential for NK cell homeostasis in vivo, it is commonly used at supraphysiological levels to induce NK cell proliferation in vitro. As a result, adoptive transfer of such IL-15–addicted NK cells is associated with cellular stress because of sudden cytokine withdrawal. In this article, we describe a dose-dependent addiction to IL-15 during in vitro expansion of human NK cells, leading to caspase-3 activation and profound cell death upon IL-15 withdrawal. NK cell addiction to IL-15 was tightly linked to the BCL-2/BIM ratio, which rapidly dropped during IL-15 withdrawal. Furthermore, we observed a proliferation-dependent induction of BIM short, a highly proapoptotic splice variant of BIM in IL-15–activated NK cells. These findings shed new light on the molecular mechanisms involved in NK cell apoptosis following cytokine withdrawal and may guide future NK cell priming strategies in a cell therapy setting.
Histochemistry as a versatile research toolkit in biological research, not only an applied discipline in pathology
Authors: Pellicciari Carlo
Published: December 2018

The impressive progress of histochemistry over the last 50 years has led to setting up specific and sensitive techniques to describe dynamic events, through the detection of specific molecules in the very place where they exist in live cells. The scientific field where histochemistry has most largely been applied is histopathology, with the aim to identify disease-specific molecular markers or to elucidate the etiopathological mechanisms. Numerous authors did however apply histochemistry to a variety of other research fields; their interests range from the microanatomy of animal and plant organisms to the cellular mechanisms of life. This is especially apparent browsing the contents of the histochemical journals where the articles on subjects other than pathology are the majority; these journals still keep a pivotal role in the field of cell and tissue biology, while being a forum for a diverse range of biologists whose scientific interests expand  the research horizon of histochemistry to ever novel subjects. Thus, histochemistry can always receive inspiring stimuli toward a continuous methodological refinement.
The importance of beech forests as reservoirs of moth diversity in Mediterranean Basin (Lepidoptera)
Authors: Infusino Marco , Scalercio Stefano
Published: December 2018

Study analyzes the macrolepidoptera assemblages in beech woodlands of the Orsomarso Mountains (Pollino National Park, Southern Italy) to assess the role of beech forests in preserving diversity in Mediterranean Basin. Research was run between 2015 and 2016 in 15 stands representative of the main successional stages of forest maturation, placed between 990 and 1,475 meters of elevation. Monthlybased sampling was performed using UV-LED light traps. A total of 33,957 individuals belonging to 410 species was collected. The community is rich and the most abundant and characteristic species (Eilema lurideola, Operophtera fagata, Campaea margaritata) are almost all trophically linked to broadleaves or lichens. The community structure appears fairly constant and recognizable in all stands over the two years of sampling. Young beech forests hosted the greatest number of species compared to other forest maturation stages, though the difference is small. The greatest differences in the community structure are found in the clearings, where generalist and/or related to the herbaceous layer species are mostly represented. Biogeographically widely distributed species prevail, 87% of them having European or Asian-European distribution. There are a number of species of faunistic interest, among which Perizoma juracolaria, Chelis maculosa, Tiliacea citrago, Poecilocampa populi, Triphosa dubitata, Sideridis reticulata, Nebula senectaria, including 13 Italian endemics such as Coenotephria antonii. Populations of many species show significant genetic diversities compared to other European populations. The Orsomarso Mountains beech forests represent an important biodiversity reservoir, even at the genetic level, and show a good degree of naturalness.

Published: December 2018

The antlions (Myrmeleontidae) of Cyprus have been poorly studied and only 13 species were known from this biogeographically interesting island. In light of new field research, we provide an updated checklist to the Cypriot antlions, including seven species reported for the first time from the island. Of these, the findings of the Middle Eastern species Distoleon laticollis and Cueta kasyi are particularly noteworthy. The Cypriot antlion fauna appears dominated by widespread Mediterranean elements, with relatively few Middle Eastern and endemic species.

In this short contribution some specimens from New Caledonia, colletcted by Dr. Geoff Monteith of the Queensland Museum of Brisbane, are studied and four new species are described and illustrated (Pachycorynus monteithi sp. n., P. flavus sp. n., P. insularis sp. n., and Zeteotomus insularis sp. n.). The known New Caledonian Xantholinini are now represented by 17 species.
Extreme prolongation of expiration breathing: Effects on electroencephalogram and autonomic nervous function
Authors: Komori Teruhisa
Published: December 2018

To clarify the physiological and psychological effects of deep breathing, the effects of extreme prolongation of expiration breathing (Okinaga) were investigated using electroencephalogram (EEG) and electrocardiogram (ECG). Participants were five male Okinaga practitioners in their 50s and 60s. Participants performed Okinaga for 31 minutes while continuous EEG and ECG measurements were taken. After 16 minutes of Okinaga, and until the end of the session, the percentages of theta and alpha 2 waves were significantly higher than at baseline. After 20 minutes, and until the end of the session, the percentage of beta waves was significantly lower than at baseline. The high frequency component of heart rate variability was significantly lower after 12 minutes of Okinaga and lasted until 23 minutes. The low frequency/high frequency ratio was significantly lower after 18 minutes of Okinaga and until the end of the session. Okinaga produced relaxation, suggesting that deep breathing may relieve anxiety. However, study limitations include potential ambiguity in the interpretation of the low frequency/high frequency ratio, the small sample, and the fact that EEG was measured only on the forehead.
The dialogic construction of patient involvement in patient-centred neurorehabilitation
Authors: Uhre Jannie
Published: December 2018

This paper explores how the practice of patient involvement in neurorehabilitation is constructed in tension-riddled professional narratives. I adopt dialogic communication theory to focus on how involvement is constructed across different roles and voices. My analysis is based on an action research project that uses a dialogical communication perspective and participatory methods to explore patient-centred care through the eyes of healthcare professionals. I argue that patient involvement is constructed as a demanding process that requires memory, presence, communicative abilities and temporal understanding of personal needs. These requirements are not explicit in the situated institutionalized practices. As well, I show how the available involvement strategies are laced with taken for granted characteristics, which fall short in the situation that arises when patients do not have the ability to participate or play the role of an active patient. The findings in this paper contribute to the growing literature on patient-centred healthcare by empirically investigating how the discursive configuration of patient, health professional and institutional practices intertwine in producing certain inherent expectations, habits and taken for granted perspectives in care delivery. I also suggest that the findings can usefully be incorporated into patient-centred care design and organizational strategies in order to take into account both the patient, relatives and healthcare professionals as vital for creating a patient-centred practice, organization and professional environment.
Variability of depolarization of aerosol particles in the megacity of Beijing: implications for the interaction between anthropogenic pollutants and mineral dust particles

Published: December 2018

Abstract. East Asia is suffering from severe air pollution problems due to intensive
anthropogenic emissions and natural mineral dust aerosols. During transport,
the aerosol particles undergo complex mixing processes, resulting in great
impacts on regional air quality, human health and climate. In this study, we
conducted a long-term observation using an optical particle counter equipped
with a polarization detection module (POPC) at an urban site in Beijing. Mass
concentrations of both PM2.5 and PM10 estimated from POPC compared
well with ground-based measurements. The results revealed that the observed
depolarization ratio (δ, termed as the ratio of the intensity of the
s-polarized signal to the intensity of the 120∘ backward scattering
signal [s/(s+p)]) for aerosol particles in the fine mode was generally
much lower in summer than that in spring as a result of predominance of
different aerosol types. Mineral dust particles in the coarse mode normally
had a large δ value (0.3±0.05) owing to their nonspherical
shape; however, particles in the fine mode mostly had water-soluble
compositions, which led to an apparent decrease of their δ values in
particular high relative humidity (RH) conditions. Because the observation
site was subject to the impact of frequent dust events in spring, the
δ value of particle at 1 µm was almost twice as high as that
(0.07±0.01) in summer. Based on size-resolved δ values,
anthropogenic pollutants, mineral dust and polluted mineral dust particles
and their contribution to local air quality could be well distinguished.
About 26.7 % of substandard days (daily averaged PM2.5 concentration
larger than 75 µg m−3) in Beijing featured high atmospheric
loading of coarse-mode particles in winter and springtime. In
particular, during severe pollution episodes in winter, the δ values
of coarse-mode particles decreased by 13 %, which implies a high
possibility of dust-related heterogeneous processes in pollution formation.
During dust events, δ values of
particles with optical size (Dp) of 5 µm evidently decreased, with an increase
of the PM2.5 ∕ PM10 ratio as well as RH, indicating the
morphological changes of mineral dust. This study confirmed that high RH
tends to promote water absorption processes on the dust surface as well as
the coating of soluble compounds, and suggested that remote sensing techniques for aerosols may
underestimate the impact of dust particles due to the complex mixing of dust and anthropogenic
particles in urban areas, and the interaction between
dust particles and pollutants should be considered well by the optical model.
Low-pressure gas chromatography with chemical ionization mass spectrometry for quantification of multifunctional organic compounds in the atmosphere

Published: December 2018

Abstract. Oxygenated volatile organic compounds (OVOCs) are formed during the oxidation
of gas-phase hydrocarbons in the atmosphere. However, analytical challenges
have hampered ambient measurements for many of these species, leaving
unanswered questions regarding their atmospheric fate. We present the
development of an in situ gas chromatography (GC) technique that, when
combined with the sensitive and specific detection of chemical ionization
mass spectrometry (CIMS), is capable of the isomer-resolved detection of a
wide range of OVOCs. The instrument addresses many of the issues typically
associated with chromatographic separation of such compounds (e.g., analyte
degradation). The performance of the instrumentation is assessed through data
obtained in the laboratory and during two field studies. We show that this
instrument is able to successfully measure otherwise difficult-to-quantify
compounds (e.g., organic hydroperoxides and organic nitrates) and observe the
diurnal variations in a number of their isomers.

Abstract. We present a new MAX-DOAS profiling algorithm for aerosols and trace gases,
BOREAS, which utilizes an iterative solution method including Tikhonov
regularization and the optimal estimation technique. The aerosol profile
retrieval is based on a novel approach in which the absorption depth of
O4 is directly used in order to retrieve extinction coefficient
profiles instead of the commonly used perturbation theory method. The
retrieval of trace gases is done with the frequently used optimal estimation
method but significant improvements are presented on how to deal with wrongly
weighted a priori constraints and for scenarios in which the a priori profile
is inaccurate. Performance tests are separated into two parts. First, we address the general
sensitivity of the retrieval to the example of synthetic data calculated with
the radiative transfer model SCIATRAN. In the second part of the study, we
demonstrate BOREAS profiling accuracy by validating the results with the help of
ancillary measurements carried out during the CINDI-2 campaign in Cabauw, the
Netherlands, in 2016. The synthetic sensitivity tests indicate that the regularization between
measurement and a priori constraints is insufficient when knowledge of the
true state of the atmosphere is poor. We demonstrate a priori pre-scaling and
extensive regularization tests as a tool for the optimization of retrieved
profiles. The comparison of retrieval results with in situ, ceilometer,
NO2 lidar, sonde and long-path DOAS measurements during the CINDI-2
campaign always shows high correlations with coefficients greater than 0.75.
The largest differences can be found in the morning hours, when the planetary
boundary layer is not yet fully developed and the concentration of trace
gases and aerosol, as a result of a low night-time boundary layer having
formed, is focused in a shallow, near-surface layer.

Published: December 2018

Abstract. Vertical and horizontal transport mechanisms for marine oil spills
are investigated using numerical model simulations. To realistically resolve
the 3-D development of a spill on the ocean surface and in the water column,
recently published parameterizations for the vertical mixing of oil spills
are implemented in the open-source trajectory framework OpenDrift
(https://doi.org/10.5281/zenodo.1300358, last access: 7 April 2018). The parameterizations include the
wave entrainment of oil, two alternative formulations for the droplet size
spectra, and turbulent mixing. The performance of the integrated oil spill
model is evaluated by comparing model simulations with airborne observations
of an oil slick. The results show that an accurate description of a chain of
physical processes, in particular vertical mixing and oil weathering, is
needed to represent the horizontal spreading of the oil spill. Using
ensembles of simulations of hypothetic oil spills, the general drift behavior
of an oil spill during the first 10 days after initial spillage is evaluated
in relation to how vertical processes control the horizontal transport.
Transport of oil between the surface slick and the water column is identified
as a crucial component affecting the horizontal transport of oil spills. The
vertical processes are shown to control differences in the drift of various
types of oil and in various weather conditions.
