Published: March 2017

Spirulina platensis (SP) is a blue-green microalga that has recently raised attention not only as a nutritional component, but also as a source of bioactivities that have therapeutic effects and may find application in medicine, including cancer treatment. In the present study we determined the cytotoxic effect of S. platensis filtrates (SPF) on human colon cancer cell line Caco-2. Three concentrations of SPF were tested—1.25%, 2.5%, and 5% (v/v). We have found that the highest concentration of SPF exerts the strongest anti-proliferative and pro-apoptotic effect on Caco-2 cultures. The SPF negatively affected the morphology of Caco-2 causing colony shrinking and significant inhibition of metabolic and proliferative activity of cells. The wound-healing assay showed that the SPF impaired migratory capabilities of Caco-2. This observation was consistent with lowered mRNA levels for metalloproteinases. Furthermore, SPF decreased the transcript level of pro-survival genes (cyclin D1, surviving, and c-Myc) and reduced the autocrine secretion of Wnt-10b. The cytotoxic effect of SPF involved the modulation of the Bax and Bcl-2 ratio and a decrease of mitochondrial activity, and was related with increased levels of intracellular reactive oxygen species (ROS) and nitric oxide (NO). Moreover, the SPF also caused an increased number of cells in the apoptotic sub-G0 phase and up-regulated expression of mir-145, simultaneously decreasing expression of mir-17 and 146. Obtained results indicate that SPF can be considered as an agent with anti-cancer properties that may be used for colon cancer prevention and treatment.
A Summary of Corrosion Properties of Al-Rich Solid Solution and Secondary Phase Particles in Al Alloys
Authors: Li Jichao , Dang Jie
Published: March 2017

The heterogeneous structure of Al alloys renders them susceptible to localized corrosion due to the different electrochemical properties existing in the Al-rich solid solution matrix and secondary phase particles. The galvanic interactions between these two phases can result in pit formation either through dissolution of the particles or corrosion of the matrix adjacent to the particles. This detrimentally localized corrosion behavior is closely related to the corrosion properties of the particles and the Al-rich matrix. The comprehensive characterization of this behavior under various and varying conditions is critical to understanding the mechanism of pit formation, selecting appropriate inhibitors, and developing protection strategies. The corrosion properties (corrosion potential, pitting potential and corrosion rate) of both secondary phase particles and Al-solid solutions in Al alloys are summarized in this review, aiming to provide a database for corrosion research applicable to the localized corrosion of Al alloys.
Cathodic Aromatic C,C Cross-Coupling Reaction via Single Electron Transfer Pathway
Authors: Qu Yang , Tateno Hiroyuki , Matsumura Yoshimasa , Kashiwagi Tsuneo , Atobe Mahito
Published: March 2017

We have successfully developed a novel cathodic cross-coupling reaction of aryl halides with arenes. Utilization of the cathodic single electron transfer (SET) mechanism for activation of aryl halides enables the cross-coupling reaction to proceed without the need for any transition metal catalysts or single electron donors in a mild condition. The SET from a cathode to an aryl halide initiates a radical chain by giving an anion radical of the aryl halide. The following propagation cycle also consists entirely of anion radical intermediates.
A Focused Multiple Reaction Monitoring (MRM) Quantitative Method for Bioactive Grapevine Stilbenes by Ultra-High-Performance Liquid Chromatography Coupled to Triple-Quadrupole Mass Spectrometry (UHPLC-QqQ)
Authors: Hurtado-Gaitán Elías , Sellés-Marchart Susana , Martínez-Márquez Ascensión , Samper-Herrero Antonio , Bru-Martínez Roque
Published: March 2017

Grapevine stilbenes are a family of polyphenols which derive from trans-resveratrol having antifungal and antimicrobial properties, thus being considered as phytoalexins. In addition to their diverse bioactive properties in animal models, they highlight a strong potential in human health maintenance and promotion. Due to this relevance, highly-specific qualitative and quantitative methods of analysis are necessary to accurately analyze stilbenes in different matrices derived from grapevine. Here, we developed a rapid, sensitive, and specific analysis method using ultra-high-performance liquid chromatography coupled to triple-quadrupole mass spectrometry (UHPLC-QqQ) in MRM mode to detect and quantify five grapevine stilbenes, trans-resveratrol, trans-piceid, trans-piceatannol, trans-pterostilbene, and trans-ε-viniferin, whose interest in relation to human health is continuously growing. The method was optimized to minimize in-source fragmentation of piceid and to avoid co-elution of cis-piceid and trans-resveratrol, as both are detected with resveratrol transitions. The applicability of the developed method of stilbene analysis was tested successfully in different complex matrices including cellular extracts of Vitis vinifera cell cultures, reaction media of biotransformation assays, and red wine.

Published: March 2017

New benzimidazolium salts 1a–c and their palladium bis-N-heterocyclic carbene complexes 2a–c and palladium PEPPSI-type complexes 3a–c were designed, synthesized and structurally characterized by NMR (1H and 13C), IR, DART-TOF mass spectrometry and elemental analysis. Then these complexes 2–3 were employed in the Suzuki-Miyaura cross-coupling reaction of substituted arenes with phenylboronic acid under mild conditions in toluene and DMF/H2O (1/1) to afford functionalized biaryl derivatives in good to excellent yields. The antibacterial activity of palladium bis-N-heterocyclic carbene complexes 2a–c and palladium PEPPSI-type complexes 3a–c was measured by disc diffusion method against Gram positive and Gram negative bacteria. Compounds 2a, 2c and 3a–c exhibited potential antibacterial activity against four bacterial species among the five used indicator cells. The product 2b inhibits the growth of the all five tested microorganisms. Moreover, the antioxidant activity determination of these complexes 2–3, using 2.2-diphenyl-1-picrylhydrazyl (DPPH) as a reagent, showed that compounds 2a–c and 3b possess DPPH antiradical activity. The higher antioxidant activity was obtained from the product 2b which has radical scavenging activity comparable to that of the two used positive controls (gallic acid “GA“ and tutylatedhydroxytoluene “BHT“). Investigation of the anti-acetylcholinesterase activity of the studied complexes showed that compounds 2b, 3a, and 3b exhibited moderate activity at 100 μg/mL and product 2b is the most active.

Published: March 2017

We have cloned, purified, and characterized a β-carbonic anhydrase (CA, EC 4.2.1.1), BpsCAβ, from the pathogenic bacterium Burkholderia pseudomallei, responsible for the tropical disease melioidosis. The enzyme showed high catalytic activity for the physiologic CO2 hydration reaction to bicarbonate and protons, with the following kinetic parameters: kcat of 1.6 × 105 s−1 and kcat/KM of 3.4 × 107 M−1 s−1. An inhibition study with a panel of 38 sulfonamides and one sulfamate—including 15 compounds that are used clinically—revealed an interesting structure–activity relationship for the interaction of this enzyme with these inhibitors. Many simple sulfonamides and clinically used agents such as topiramate, sulpiride, celecoxib, valdecoxib, and sulthiame were ineffective BpsCAβ inhibitors (KI > 50 µM). Other drugs, such as ethoxzolamide, dorzolamide, brinzolamide, zonisamide, indisulam, and hydrochlorothiazide were moderately potent micromolar inhibitors. The best inhibition was observed with benzene-1,3-disulfonamides—benzolamide and its analogs acetazolamide and methazolamide—which showed KI in the range of 185–745 nM. The inhibition profile of BpsCAβ is very different from that of the γ-class enzyme from the same pathogen, BpsCAγ. Thus, identifying compounds that would effectively interact with both enzymes is relatively challenging. However, benzolamide was one of the best inhibitors of both of these CAs with KI of 653 and 185 nM, respectively, making it an interesting lead compound for the design of more effective agents, which may be useful tools for understanding the pathogenicity of this bacterium.

Published: March 2017

Antimicrobial peptides (AMPs) play a pivotal role in the innate immune responses to Helicobacter pylori (Hp) in humans. β-Defensins, a class of cationic arginine-rich AMPs, are small peptides secreted by immune cells and epithelial cells that exert antimicrobial activity against a broad spectrum of microorganisms, including Gram-positive and Gram-negative bacteria and fungi. During Hp infections, AMP expression is able to eradicate the bacteria, thereby preventing Hp infections in gastrointestinal tract. It is likely that gastric β-defensins expression is increased during Hp infection. The aim of this review is to focus on increased knowledge of the role of β-defensins in response to Hp infection. We also briefly discuss the potential use of AMPs, either alone or in combination with conventional antibiotics, for the treatment of Hp infection.

Premier signalement du Gastrotriche d'eau douce Neogossea fasciculata (Daday, 1905) en Guyane française (mare des caïmans, août 2004). Sous sa forme typique, cette espèce n'est actuellement connue que du continent américain. La forme européenne de cette espèce s'en distingue par sa morphologie céphalique, ce qui justifie qu'elle en soit considérée comme une sous-espèce, décrite ici sous le nom de N. fasciculata subsp. beau-champi, subsp. nov.

Une compilation de données acquises entre 1976 et 2004, dans les anciens chenaux fluviaux de la zone alluviale du Haut-Rhône français, permet de dresser un premier inventaire des sites où le gastéropode Anisus vorticulus (Troschel 1834) a été mentionné. Cette espèce figure depuis 2004 en annexes de la «Directive habitats » européenne. 11 sites, sur les 43 prospectés, ont hébergé l'espèce au cours de cette période. La présence actuelle (2002-2004) de l'espèce est établie dans 6 sites. Dans le secteur de Brégnier-Cordon (départements de l'Ain et de l'Isère) où ces 6 sites sont situés, les populations de cette espèce semblent bien établies et présentent localement des densités remarquables (jusqu'à 664 individus/m2). Quelques caractéristiques des sites concernés sont fournies ainsi que des recommandations concernant l'étude et la conservation de cette espèce qui demeure peu connue à l'échelle européenne.

Published: March 2017

The authors complete and modify results published in 2003 on trophic relationships between seed-beetles of the French fauna and their larval host plants. New data are given for France, Italy and Greece. Forty-four new host plants were identified, which constitutes for several beetle species the very first biological data available. The diet of 86 % of the seed-beetles in the three countries is now more or less precisely known. The previously expressed hypothesis, according to which any given beetle species will feed on a single plant species, genus or tribe, is confirmed in most cases.

Notre étude porte sur l'analyse quantitative de la stratification verticale (sous-bois et canopée supérieure) de l'entomofaune de neuf sites en forêt tropicale humide de la presqu'île de Masoala, sur le rivage oriental de la baie d'Antongil (Madagascar). Nous avons pu accéder à la canopée grâce à la Bulle à Hélium®, à la Luge des Cimes ®, à l'Icos® et au Radeau des Cimes®. Les Insectes ont été collectés par battage du feuillage et avec des pièges jaunes à glu. Les Arthropodes de la canopée supérieure sont significativement plus abondants que dans le sous-bois. Ce type de stratification verticale de l'entomofaune de la forêt tropicale confirme dans ses grandes lignes, malgré quelques différences, le modèle que nous avions établi au Cameroun et affiné au Gabon. L'analyse par guildes montre que certains de ces groupes ont nettement une strate préférentielle (en particulier les Phyllophages et les Piqueurs-suceurs pour la canopée), ce qui est directement fonction de la répartition verticale des ressources alimentaires. L'assignation à une guilde semble être un instrument pertinent pour étudier l'écologie et la stratification verticale des Insectes de la forêt tropicale.
Limonius minutus (Linnaeus, 1758) et Limonius poneli nov. sp„ deux espèces jumelles confondues sous un même nom (Coleoptera, Elateridae)
Authors: Leseigneur Lucien , Mertlik Joseph
Published: March 2017

Elater minutus Linnaeus, 1758 a fait l'objet d'une très brève description par Linné, sans la prise en compte, bien sûr, des genitalia. La découverte de deux formes nettement différentes de paramètres conduit à penser que, sous ce même nom, existent deux espèces distinctes impossibles à séparer par les caractères externes. Tous les spécimens-types des synonymes ayant disparu, il est nécessaire de choisir arbitrairement l'une des deux formes comme Limonius minutus (Linnaeus) s. str., l'autre recevant un nouveau nom, L. poneli.

La réception de Linné et le mouvement linnéen à Lyon de 1750 à 1830
Authors: Bange Christian
Published: March 2017

Linnaeus reception in Lyons from 1750 to 1830

During the second half of the XVIIIth century, as many provincial cities in France, several botanical gardens were established in Lyons, mainly at the Ecole royale vétérinaire (1763) and later at the Ecole centrale du Rhône (1795), the first by Claret de la Tourrette (with the help of Rozier), the second by Gilibert. These two botanists, and some other Lyonnese naturalists (as Villers, Jolyclerc and Mouton-Fontenille), were very active in the diffusion of Linnean principles, either by teaching or by reediting or translating Linnaeus works. In 1822, some of their ancient students met together to found the Société Linnéenne de Lyon, aimed at the study of natural sciences.
Nuklearmedizin in Deutschland
Authors: Marienhagen Jörg , Menhart Karin , Grosse Jirka , Hellwig Dirk
Published: March 2017

Ziel: Aktualisierte Darstellung des Spektrums nuklearmedizinischer in-v/Vo-Untersuchungen und Therapien aus offiziellen Statistiken zur ambulanten und stationären Patientenversorgung sowie von Trends in der Struktur der nuklearmedizinischen Versorgung in Deutschland. Methoden: Die Gesundheitsberichterstattung des Bundes, die Frequenzstatistik der Kassenärztlichen Bundesvereinigung und Statistiken der Bundesärztekammer wurden abgefragt und durch selektive Literaturrecherchen ergänzt. Ergebnisse: Weiterhin werden vornehmlich Schilddrüsen, Knochen und Herzen nuklearmedizinisch untersucht. Bei deutlich gestiegenem Einsatz von PET/CT und SPECT/ CT sind einfache Szintigraphieleistungen rückläufig. Myokard-, Lungen-, Lymph- und Hirn-Szintigraphien werden zunehmend angefordert, Skelett- sowie Schilddrüsenszintigraphien gehen zurück. Die Inanspruchnahme nuklearmedizinischer Vertragsärzte stieg jährlich im Schnitt um 4 % (2009: 2 164 664; 2015: 2 687 359). Die Zahl vertragsärztlich tätiger Nuklearmediziner stieg deutlich an (2009: 756; 2015: 939; Zuwachs 24 %) und ist nach der Niederlassungssperre seit 2013 konstant. Der Frauenanteil bei nuklearmedizinischen Facharztanerkennungen nimmt zu (Anteil aktuell 46 %). In Krankenhäusern werden mehr PET(/CT)-Scanner (2009: 97; 2015: 125) und weniger Gammakameras (2009: 594; 2015: 550) betrieben. Die Zahl extrathyreoidaler (auch ambulanter) Therapien stieg weiter. Schlussfolgerung: Bei vermehrter Nutzung von Hybridtechnologien zeigt das nuklearmedizinische Spektrum positive Trends besonders bei Nuklearkardiologie, Neuronuk- learmedizin und extrathyreoidalen Therapien. Diese Entwicklungen sind bei der Novellierung der Weiterbildungsordnung und der studentischen Lehre zu beachten.
Imaginer des scénarios pour donner du sens à sa vision du futur

Published: March 2017

L’entrepreneur est confronté à un environnement qui déstructure et remodèle sans cesse la vision qu’il a de son projet. Il a donc besoin de méthodes pour stabiliser et formaliser sa vision afin de la partager avec d’autres. Il a accès à une palette d’outils assez large et plutôt bien ancrée dans les pratiques : business model canvas , lean start-up , approche effectuale... Cette palette omet pourtant deux angles utiles à la construction d’une vision pour un entrepreneur : la projection dans un futur en rupture avec l’existant et l’inclusion du sens qu’a le projet pour son porteur. La méthode des scénarios apporte ces deux angles de vue. Elle a pour vertu de projeter dans le futur n’importe quel « objet » et de faire ressortir les modèles mentaux peu conscients. Nous l’avons testée au cours d’ateliers avec des entrepreneurs, des chercheurs, des étudiants en entrepreneuriat.

Pourquoi la gauche de gouvernement a-t-elle oublié le travail ?
Authors: Méda Dominique
Published: March 2017

Un retour sur les cinq années de la présidence de François Hollande met en évidence la distance entre les promesses de campagne et la politique économique de l’offre réellement menée. En ce qui concerne plus particulièrement le travail, la loi sur la sécurisation de l’emploi et la loi El Khomri ont résolument tourné le dos à la justice sociale en faveur d’une politique « sociale-libérale ». Pour Dominique Méda, ce tournant, qui n’est pas sans rappeler celui de 1982-1983, est le résultat non seulement de la concurrence entre des responsables politiques mais aussi entre des coalitions de réseaux et d’idées et le poids dans ces derniers, des organisations patronales, des think tanks et... des économistes.
Républicanisme critique et religion
Authors: Laborde Cécile
Published: March 2017

Depuis quelques années, on peut noter une dérive communautariste du républicanisme français, y compris dans les rangs de la gauche. Selon cette interprétation, la nation est définie de manière substantialiste, comme adhésion à une conception particulière du bien et de la vie bonne – un mode de vie français, caractérisé par des modes de sociabilité publique et privée. Contre cette dérive identitaire, il convient de défendre un républicanisme de la non-domination. Dans ce cadre, l’important est non que les citoyens s’émancipent de leur croyance religieuse, mais qu’ils ne soient pas dominés par des pouvoirs arbitraires – religieux, patriarcaux, économiques, administratifs, etc. La république de la non-domination serait ainsi un antidote à la laïcité identitaire qui ne cesse de gagner du terrain.
La social-démocratie en Europe : crise terminale ou nouveau « champ de bataille » ?
Authors: Escalona Fabien
Published: March 2017

Dans les années 1990, dans une période de croissance économique, l’abandon d’une « social-démocratie keynésienne » et son remplacement par une « social-démocratie de marché » a permis aux partis sociaux-démocrates de ralentir leur déclin et de connaître d’importants succès électoraux. Depuis 2008, dans le contexte d’une crise économique sans précédent et en l’absence de croissance, l’accommodement aux règles du capitalisme financier est devenu synonyme de renoncement total aux dogmes néolibéraux. La social-démocratie est à un tournant historique car cette situation inédite pourrait rapidement mettre en jeu son existence comme force modérée et majoritaire à gauche. Mais aucune dirigeante de premier plan (à l’exception, timidement, du PS portugais et, difficilement, de Jeremy Corbyn), ne semble vouloir pour le moment remettre en cause cette ligne d’accompagnement acritique du capitalisme.

Testing was carried at prismatic samples of dimension 40 × 40 × 160 mm. The investigated mechanical properties were dynamic modulus of elasticity, dynamic shear modulus, flexural strength and compressive strength for the 28 days old samples. The results obtained from these materials were compared with reference material.
Feasibility Study for Onboard Marine Debris Gathering and Recycling
Authors: Kang Hee Jin , Chun Tae-Byung , Ahn Haeseong , Yim Geun-Tae
Published: March 2017

AbstractIt is well known that approximately 90% of all marine debris consists of reusable plastics. Small plastic particles are easily swallowed and disturb marine ecosystems. However, cleaning up marine debris is difficult because of its economic feasibility. Though there
are many proven land-based recycling processes available, the high costs of gathering marine debris and transporting it adds to marine debris-related problems. Marine debris cleanup is challenging despite various studies that point to its importance. Therefore, we discuss a recycling chain
that concerns gathering, transporting, classifying, recycling, and disposing of marine debris on the ocean. In this study, cost-effective ways of cleaning up large-scale marine litter such as garbage patches are studied. As plastics generate toxic materials during recycling and disposing,
this study focuses on how to apply technological potential and meets the required rules and regulations for establishing an economically and environmentally friendly recycling chain for marine debris. In this study, a new type of marine platform is also studied and suggested for a low-energy
consumption process and to recycle this debris into oil, gas, and raw materials.
Immunohistochemistry detected and localized cannabinoid receptor type 2 in bovine fetal pancreas at late gestation

Published: March 2017

At present, data on the endocannabinoid system expression and distribution in the pancreatic gland appear scarce and controversial as descriptions are limited to humans and laboratory animals. Since the bovine pancreas is very similar to the human in endocrine portion development and control, studies on the fetal gland could prove to be very interesting, as an abnormal maternal condition during late pregnancy may be a predisposing trigger for adult metabolic disorders. The present investigation studied cannabinoid receptor type 2 presence and distribution in the bovine fetal pancreas towards the end of gestation. Histological analyses revealed numerous endocrinal cell clusters or islets which were distributed among exocrine adenomeri in connectival tissue. Immunohistochemistry showed that endocrine-islets contained some CB2-positive cells with a very peculiar localization that is a few primarily localized at the edges of islets and some of them also scattered in the center of the cluster. Characteristically, also the epithelium of the excretory ducts and the smooth muscle layers of the smaller arteries, in the interlobular glandular septa, tested positive for the CB2 endocannabinoid receptor. Conse - quently, the endocannabinoid system, via the cannabinoid receptor type 2, was hypothesized to play a major role in controlling pancreas function from normal fetal development to correct metabolic functioning in adulthood.

The integration of information and communication technologies into foreign language teaching/learning has become indispensable, nay imperative, in today’s teaching and learning environment. This is so as computer literacy, together with reading and writing literacy are generally considered as skills needed by students to succeed in today’s technologically developed world. Furthermore, modern technologies are generally viewed as having potentials of impacting and revolutionizing the teaching and learning of all academic subjects. In Nigeria, the use of ICTs in secondary and tertiary educational institutions is more of a myth than a reality and this has caused the traditional approach to principally be considered in language teaching in schools within the Federation. This paper explored some of the negative effects of this traditional approach, particularly to foreign language teaching. It also examined the prospects and challenges facing the use of ICTs in foreign language teaching in Nigeria. It argued that ICTs have the potentials of improving the quality of language teaching and learning and of facilitating access to such teaching and learning. It also has the potentials of enhancing language competence and learners’ interaction among others. However, this modernist approach is faced with challenges such as ineffective education policies, absence of ICT facilities in schools, overcrowded classrooms and erratic power supply among others.

Published: March 2017

This essay is a developed version of a presentation made at a workshop titled “ChinAfrica Under Construction”. The workshop was facilitated and hosted by Goethe Institute Lagos. It was conducted by two artist researchers, Danial Kotter and Jochen Becker from Berlin Germany. According to their consultant Jahman Anikulapo, it is a research and art project that is exploring the traces and cultural links between the African continent and China. He says it also dealt with the development of the urban land scape of Lagos with the aid of Chinese investors. This work therefore, dwelled more on the Theatre/Entertainment technology related aspects. It focuses on the art of manufacturing, purchase and its attendant ripple effects on the economy with tourism being one of them. In it, an attempt was made at summarizing views of some participants at the workshop. My briefing was to discuss my professional encounter and experience with manufacturing China as a theatre designer and technologist. Using the Focus Group Discussion (FGD) methodology suitable for the workshop.

The aim of present study was to isolate, characeterise and evaluation anticoagulant properties of the isolated compound from aqueous extract of Cestrum nocturnum using aPTT-Activated Partial Thromboplastin Time, PT- Prothrombin Time & TT-Thrombin Time as standard procedures.

From all the result it can be concluded that water extract of Cestrum nocturnumplant was found to be best among all the extract under study and from the isolates of water extract of Cestrum nocturnum plant AE5 was found to be best activity (anti-platelet, Fibrinolytic and anti-coagulant). Further fractionation of water extract generated two isolates AE5a & AE6a and after their pharmacological activity they were found to be potent phytochemical constituents. From the structural elucidation study of AE5a & AE6a were identified as Rutin and quercetin respectively.

From this study it was concluded that the flavoinoidal compound i.e. Rutin and Quercetin were present in the Cestrum nocturnum plant and they both responsible for the anti-platelet, Fibrinolytic and anticoagulamt activity of plant.
A new balance formula to estimate new particle formation rate:
reevaluating the effect of coagulation scavenging
Authors: Cai Runlong , Jiang Jingkun
Published: March 2017

Abstract. A new balance formula to estimate new particle formation rate is proposed. It was derived from aerosol general dynamic equation in the discrete form and then converted into an approximately continuous form for analysing data from new particle formation (NPF) field campaigns. The new formula corrects the underestimation of the coagulation scavenging effect occurred in previously used formulae. It also clarifies the criterions in determining upper size bound in measured aerosol size distributions for estimating new particle formation rate. A NPF field campaign was carried out from March 7th to Apr. 7th, 2016, in urban Beijing, and a diethylene glycol scanning mobility particle spectrometer equipped with a miniature cylindrical differential mobility analyser was used to measure aerosol size distributions down to ~1 nm. 11 typical NPF events were observed during this period. Measured aerosol size distributions from 1 nm to 10 μm was used to test the new formula and those widely used ones. Previously used formulae that perform well in relatively clean atmosphere where nucleation intensity is not strong were found to underestimate the comparatively high new particle formation rate in urban Beijing because of their underestimation or neglect of the coagulation scavenging effect. Coagulation sink term is the governing component of the estimated formation rate in the observed NPF events in Beijing, and coagulation among newly formed particles contributes a large fraction to the coagulation sink term. Previously reported formation rates in Beijing and in other locations with intense NPF events might be underestimated because the coagulation scavenging effect was not fully considered, e.g., formation rates of 1.5 nm particles in Beijing are underestimated by 58.9 % on average if neglecting coagulation among particles in nucleation mode.
Ionospheric response to magnetar flare: signature of SGR J1550–5418 on coherent ionospheric Doppler radar
Authors: Mahrous Ayman
Published: March 2017

Abstract. This paper presents observational evidence of frequent ionospheric perturbations caused by the magnetar flare of the source SGR J1550–5418, which took place on 22 January 2009. These ionospheric perturbations are observed in the relative change of the total electron content (ΔTEC/Δt) measurements from the coherent ionospheric Doppler radar (CIDR). The CIDR system makes high-precision measurements of the total electron content (TEC) change along ray-paths from ground receivers to low Earth-orbiting (LEO) beacon spacecraft. These measurements can be integrated along the orbital track of the beacon satellite to construct the relative spatial, not temporal, TEC profiles that are useful for determining the large-scale plasma distribution. The observed spatial TEC changes reveal many interesting features of the magnetar signatures in the ionosphere. The onset phase of the magnetar flare was during the CIDR's nighttime satellite passage. The nighttime small-scale perturbations detected by CIDR, with ΔTEC/Δt  ≥  0.05 TECU s−1, over the eastern Mediterranean on 22 January 2009 were synchronized with the onset phase of the magnetar flare and consistent with the emission of hundreds of bursts detected from the source. The maximum daytime large-scale perturbation measured by CIDR over northern Africa and the eastern Mediterranean was detected after ∼ 6 h from the main phase of the magnetar flare, with ΔTEC/Δt  ≤  0.10 TECU s−1. These ionospheric perturbations resembled an unusual poleward traveling ionospheric disturbance (TID) caused by the extraterrestrial source. The TID's estimated virtual velocity is 385.8 m s−1, with ΔTEC/Δt  ≤  0.10 TECU s−1.
Also tropical freshwater ostracods show a seasonal life cycle

Published: March 2017

Abstract. Isotopic signatures of ostracod shells became common proxies for the reconstruction of paleo-environmental conditions. Their isotopic composition is the result of the composition of their host water and the phenology and ecology of the target species. The sum of spatial and temporal variations from environmental factors in the species habitat defines the maximum isotopic variation of a population during the time of their shell formation. Here we present isotopic signatures (δ18O, δ13C) of living Cytheridella ilosvayi (Ostracoda) and chemical and isotopic compositions of 14 simultaneously sampled freshwater habitats in South Florida and instrumental data of the region. The chemical and isotopic compositions of the selected sites characterize the different habitats and show the influence of the source water, biological activity and the duration of exposure to the surface. Isotopic signatures of C. ilosvayi shells correlate well with the isotopic composition of their host waters. Within-sample variability of repeated isotopic measurements of ostracod shells reflect habitat dependent ranges and indicate temperature and the δ18O composition of precipitation (δ18Oprec) as regional environmental factors responsible for the population variation. Instrumental data of water temperature and δ18Oprec were used to calculate the monthly variation of a theoretical calcite in rivers of Florida showing distinct seasonal variations in values and ranges. Different configurations of the theoretical calcite were compared to the within-sample variability to identify possible calcification periods of C. ilosvayi. For a plausible calcification period the ostracod isotopic range has to correlate with mean values of the theoretical calcite with a slight positive offset (vital effect) and the extension of the theoretical calcite range. The tested model suggests a seasonal calcification period of C. ilosvayi in early spring. The surprising seasonality of a tropical ostracod life cycle is probably coupled to the hydrologic cycle of Florida. The results of this study contribute to the application of ostracod isotopes in modern calibration studies and their potential use in paleontology.

The Impact of Mobile Device Use on Shopper Behaviour in Store: An Empirical Research on Grocery Retailing
Authors: Bellini Silvia , Aiolfi Simone
Published: March 2017

Over the last decade, retailers and manufacturers alike are increasing their attention to the role of instore mobile technology use with the aim to understand its impact on consumers’ decision making process. The rise of the mobile channel, in fact, has produced disruptive changes in shopping habits designed to gradually reduce the effectiveness of in-store marketing levers in influencing shopping behaviour.This topic is of paramount importance in grocery sector since retailers and manufacturers devote a lot of investments in instore marketing activities with the aim to influence consumers’ decisions and stimulate impulse purchases. Nevertheless, there are few contributions about the influence of the mobile technology in a retail setting and its effects on buying behavior inside the store.Our research intends to explore the impact of in-store mobile technology use on shopper behavior instore in order to understand its effects on planned versus unplanned purchases. According to our preliminary results, consumers using mobile technology instore make less unplanned items and fail to purchase more planned items. Moreover, the use of mobile technology negatively impacts shoppers’ ability to recall in-store stimuli. Our findings are interesting for both retailers and manufacturers who are looking for new ways to better address their marketing efforts and increase consumers’ engagement instore.
