Remarks: Holoparasitus madridensis sp. nov. is most closely related to the species in which males are characterized by a trispinate gnathotectum with a slender prong and two similar short lateral spines, and by a chelicera having denticles on the inner margin of both digits and a slightly curved spermatodactyl. These are: H. mallorcae Juvara-Bals, 1975 and H. vaucheri Juvara-Bals, 2008 from Algeria and H. mahnerti Juvara-Bals, 2008 from Morocco. The new species is distinguished by the shape of its corniculus, the sharp protuberance, between setae v1 and v2 on palptrochanter and the slightly arched spermatodactyl. Females differ from other species with two protrusions on the posterior margin of the endogynium (H. mallorcae, H. vaucheri, H. gibber Juvara-Bals & Witalinski, 2000) by the two protrusions being short and straight, the endogynial sac without denticles and the subapical epigynial structure formed like an ovoid disc.Published as part of Ilinca Juvara-Bals, 2017, New and rare species of Holoparasitus Oudemans, 1936 (Acari, Gamasida, Parasitidae) from the Athias-Henriot Collection, pp. 225-239 in Revue suisse de Zoologie 124 (2) on pages 226-228, DOI: 10.5281/zenodo.89350

Le bal et le masque carnavalesques, un enjeu patrimonial. Discussion
No full textDifférence entre les bals masqués d\u27ailleurs et les bals paré-masqués de Guyane.
Le bal paré-masqué de Guyane renvoi à la séduction du touloulou par le costume qu\u27il porte, il est dans l\u27exhibition.
Il comporte un avant, un pendant, et un après dancing. Les femmes se préparent et vont se retrouver dans la plus grande discrétion, pour préparer leurs toilettes, s\u27habiller ensemble, vont être marrainées avec quelqu\u27un de plus âgé qui leurs transmettent les codes, les symboles, les rites : l\u27anonymat, l\u27anonymat à travers le vêtement, le parlé, la démarche...etc.
Le bal paré-masqué de Guyane, c\u27est tout un ensemble de rite, ce qui le distingue des autres bals masqués d\u27ailleurs
Ouverture du colloque international
No full textCe colloque bals masqués et d\u27ailleurs : identités imaginaires en question, constitue un vrai défi, une vrai gageure. C\u27est une première en Guyane de mettre en place un colloque portant sur les bals masqués et parés-masqués. Étant en période de liesse, de fête, et montrer qu\u27il est possible de s\u27arrêter pour pourvoir prendre de la distanciation, réfléchir sur ce sujet festif, pouvant être un objet d\u27études scientifiques, et patrimoniales. Le cadre de ce colloque est bien simple, allier la théorie, la pratique, l\u27immersion au plaisir
On theories for researching sustainability
No full textRecent systematic literature reviews have mapped the use of theoretical perspectives in purchasing and supply chain management (PSCM) research (Chicksand et al., 2012; Spina et al.,
2016). These show that transaction cost economics (TCE) and the resource-based view (RBV)
are the dominant theories in PSCM research, although a wide array of theoretical perspectives
can also be identified. However, TCE and the RBV are old theories that were not developed to
guide research in PSCM, and we would question their suitability for researching sustainable
PSCM phenomena. In fact, literature reviews that focus on sustainable PSCM (Johnsen et al.,
2017; Gimenez and Tachizawa, 2012; Quarshie et al., 2016) show that when researchers carry
out studies related to sustainable PSCM they are driven by a different set of theories.
In this chapter we discuss why researchers in sustainable PSCM tend to opt for different
theoretical perspectives to guide their research, and why TCE and the RBV are relatively rare.
We unpack the reasons why theories that are applicable to PSCM in general may not be easily
transferrable or appropriate to research that focuses on sustainability. In brief, we argue that
the reasons are twofold. Firstly, the inherent long-term nature of sustainability, as opposed
to, for example, the short-term nature of buyer‒supplier exchanges or transactions, requires
theory that focuses on long-term developmental processes. Secondly, the traditional theories
used in PSCM research are limited when researchers seek to understand sustainability from
an interorganizational systems (or ecosystems) perspective, focused on networks of actors or
stakeholders
Patogenicidad del hongo Beauveria bassiana (Bals.) Vuill. sobre la chinche Monalion dissimulatum distant plaga del cacaotero Teobroma Cacao L.
No full textEnsayos previos con varias especies de hongos entomopatógenos sobre la chinche Monalion dissimulatum Distant (Hem.; Miridae) dieron prioridad al patógeno Beauveria bassiana (Bals.) Vuill. Se evaluaron dos cepas de B. bassiana una procedente de Metamasius hemipterus sericeus (Olivier) (Col; Curculionidae) (Bb T 011) y otra aislada de M. dissimulatum (Bb 012), a dosis crecientes de 1 x 106,2.5 X 103,5 X 103,7.5 X 103 y 1 X 109 conidias/ml. Todos los insectos tratados, independiente de su estado de desarrollo biológico, fueron susceptibles al ataque patogénico de las dos cepas. Para ambas cepas fungosas, la dosis a la cual se obtuvo el mayor porcentaje de mortalidad significativa estuvo entre 2.5 x 103 y 7.5 X 103 conidias/ml, con mortalidades que variaron entre 33.75 - 49.75 y 43.75 - 62.5 para Bb T 011,68.75.86.87 y 78.12-89.37 para Bb 012 al cabo de 10 y 15 días respectivamente. La cepa Bb 012 fue más virulenta sobre M. dissimulatum que Bb T 011.Previus test with several entomopathogenic fungus species on Monalonion dissimulatum Distant bug (Hem.; Miridae) gave priority to 1he pathogen Beauveria bassiana (Bals.) Vuill. Two B. bassiana strains were evaluated: one of them comming from Metamasius hemipterus sericeus (Olivier) (Col.; Curculionidae) (Bb T 011) and the other isolated from M. dissimulatum (Bb 012), to 1 x 106,2.5 X 103,5 X 108,7.5 X 103 and 1 x 109 conidium/ml increasing dosage. All insects treated independently of its biologycal state of development were susceptibles to 1he pathogenic attack of 1he two strains. For OO1hfungis strains 1he dosage at which a higher percentage of significant mortality was obtained ranged between 2.5 x 103 and 7.5 x 1011 conidium/ml with mortality was ranged between 33.75 -49.75 and 43.75 - 62.5 for Bb T 011, 68.75 - 86.87 and 78.12- 89.37 for Bb 012 in 10 and 15 days respectivetly

No full textHoloparasitus aquilinus sp. nov. Fig. 3 Holotype: Male; Morocco, Monte Lachab (Lechhab) near Beni Bajale (Beni Bejalle)-Beni Bouchaib, west Rif, near a spring, alt. 1700 m, leaf litter from Quercus ilex L.; 2.04. 1959 (Sp. 656). Paratype: 1 female; same data as for holotype. Diagnosis: Chelicera of male apex with movable digit hooked; fixed digit slightly curved, with 6-7 denticles, spermatodactyl arched. Epigynium with a long triangular apex and 2 spine-like lateral prongs; subapical epigynial structure a large slightly denticulate strip. Etymology: The species name is a Latin cognomen derived from “ aquila ” = eagle, meaning “the eaglelike”, and refers to the shape of the apex of the movable digit of the male chelicera being hooked like the beak of an eagle. Description of male: Length of squashed idiosoma 600-624. Dimensions of some podonatal setae: j1 = 30 others 24; opisthonatal setae very short, 6-7 long. Length of peritrematal shield 192-204. Ventral idiosoma: Sternogenital shield reticulated. Genital lamina with anterior margin rounded and with subgenital sclerite rectangular (Fig. 3C). Length of st1 = 36. Distance between setae: st1-st1’ = 72, st2-st2’ = 84, st3-st3’ = 96, st4-st4’ = 66. Gland pore gv1 and gv2 simple. Gnathosoma: Gnathotectum trispinate, with a large triangular central prong, with rounded apex and two tiny lateral spines (Fig. 3E). Corniculi conical, with small, sharp protuberance situated medially (Fig. 3B). Palptrochanter without protuberance, setae v1 and v2 pilose. Hypognathal groove with 4 large, non-denticulate rows. Chelicera (Fig. 3 A): straight fixed digit with 1 denticle above pilus dentilis and 6 more below it; movable digit (96 long) with hooked apex, 4 denticles and a tooth on internal margin; arm of spermatodactyl arched; arthrodial membrane with short brush-like process. Legs: Coxa II with a fan-shaped ridge of 7-9 tiny denticles located anterolaterally (Fig. 3 F). Leg II armed as follows (Fig. 3D): rounded femoral apophysis and oval, inward bent axillary process, their apices at same level; between them a small protuberance. Triangular genual spur located near distal margin of the segment. Rectangular tibial apophysis 30 long, its apex slightly concave. Measurements: tarsus I = 156; tarsus IV =144. Description of female: Length of squashed dorsal idiosoma 672. Length of some setae: on podonotum j1 = 25, r1 = 12, others 36; opisthonotum with tiny setae, their length 6-12. Length of peritrematal shield 221. Ventral idiosoma: Presternal plate serrated. Sternal shield reticulated, gland pore gv1 under seta st3 on posterior margin; length of sternal setae 48-50 (Fig. 3 G). Paragynial shield with small rounded posterior protrusions and metagynial sclerite ellipsoidal (Fig. 3 I). Epigynium: anterior margin with two lateral spines and long median apex (90 long); subapical structure a basal slightly denticulate strip (Fig. 3 H). Gland pore gv2 simple. Endogynium: a simple oval cup covered by a hyaline membrane and two rounded protrusions (Fig. 3 J). Measurements: epigynium: height =180, basal width = 192; h/b = 0.94; Gnathosoma: Only the following character discernible: palptrochanter without protuberance between simple v1 and pilose. v2 Legs: Length of tarsus I and IV = 180 long. Remarks: I examined only a female and a male, both not in very good condition, but the main features which distinguish the new species from others in the mallorcae- group could be properly observed. The female of H. aquilinus sp. nov. can be distinguished by the long triangular apex on the anterior margin of the epigynium and by the endogynium being a simple, oval cup. The male is easily recognizable by the shape of the chelicera. More material will be necessary in order to discern other characters especially those of the endogynium.Published as part of Ilinca Juvara-Bals, 2017, New and rare species of Holoparasitus Oudemans, 1936 (Acari, Gamasida, Parasitidae) from the Athias-Henriot Collection, pp. 225-239 in Revue suisse de Zoologie 124 (2) on page 230, DOI: 10.5281/zenodo.89350
Self-assembly of gas-phase synthesized magnesium nanoparticles on room temperature substrates
No full textAbstract: Magnesium nanoparticles (NPs) with initial size in the 10-50 nmrange were synthesized by inert gas condensation under helium flow and deposited on room temperature substrates. The morphology and crystal structure of the NPs ensemble were investigated as a function of the deposition time by complementary electron microscopy techniques, including high resolution imaging and chemical mapping. With increasing amount of material, strong coarsening phenomena were observed at room temperature: small NPs disappeared while large faceted NPs developed, leading to a 5-fold increase of the average NPs size within a few minutes. The extent of coarsening and the final morphology depended also on the nature of the substrate. Furthermore, large single-crystal NPs were seen to arise from the self-organization of primary NPs units, providing a mechanism for crystal growth. The dynamics of the self-assembly process involves the basic steps of NPs sticking, diffusion on substrate, coordinated rotation and attachment/coalescence. Key features are the surface energy anisotropy, reflected by the faceted shape of the NPs, and the low melting point of the material. The observed phenomena have strong implications in relation to the synthesis and stability of nanostructures based on Mg or other elements with similar features
