Published: June 2018

The aim of the study was to evaluate the value of clinical prognostic factors for survival of patients with invasive urinary bladder cancer treated with radical cystectomy, chemotherapy, and radiotherapy. Material and methods. A total of 115 patients with invasive urinary bladder cancer were analyzed. Twenty-three patients with invasive urinary bladder cancer (pT2–T4) were treated according to the protocol of a prospective clinical study. In all the cases, transurethral resection was followed by radiation and chemotherapy. A total dose of 54–60 Gy of radiotherapy was delivered by daily fractions of 1.8–2.0 Gy each. Simultaneous chemotherapy was started on the same day as radiotherapy; gemcitabine at a dose of 175–300 mg/m2 was delivered once a week intravenously for 6 weeks. Individual patient data was analyzed in a retrospective part of the study. Radical cystectomy was performed to 46 patients with invasive urinary bladder cancer, and radiotherapy was delivered to 46 patients. Inclusion criteria for patients into a prospective or retrospective trial were equal. We evaluated a prognostic value of various clinical factors for patients treated with radical cystectomy, chemoradiation with gemcitabine, and radiation alone. Results. The 3-year overall survival in the cystectomy group was 51.1%, in the chemoradiation group 38.0%, and in the radiotherapy group 26.9% (P=0.001). In univariate analysis in the chemoradiation group, completion of treatment according to the protocol showed a significant influence on overall survival (P=0.03). In the radiation group, completion of treatment according to the protocol showed a significant influence on overall survival too (P=0.01). In the radical cystectomy group, an important factor was a complete or incomplete TUR (P=0.02). Multivariate analysis showed a significance of hydronephrosis (P=0.03) and T stage (P=0.04) in the radiation therapy group. Comorbidity was found to be an independent prognostic factors in the chemoradiation group (P=0.02). Conclusions. The best 3-year overall survival was in the radical cystectomy group. Chemoradiation with gemcitabine could be offered as an alternative to patients refusing cystectomy. Better overall survival in the chemoradiation group was for patients without comorbidities and when treatment protocol was completed.

Aim. To compare the value of intravenous contrast-enhanced ultrasonography (US), intravenous contrast-enhanced computed tomography (CT), and magnetic resonance imaging (MRI) in the diagnosis of hepatic hemangiomas. Material and methods. The study enrolled 48 patients, aged between 20 and 79 years (35 [72.9%] women, 13 [27.1%] men; mean age, 53.5±12.855 years), who were examined and treated in the Departments of Gastroenterology, Surgery, and Oncology, Hospital of Kaunas University of Medicine, in the year 2007. All patients underwent intravenous contrast-enhanced US, intravenous contrast-enhanced CT, and MRI and were diagnosed with hepatic hemangioma according to the findings of these examinations. Results. The size of hemangiomas was ≤2.0 cm in 20 cases (41.7%) and >2.0 cm in 28 (58.3%). No association between hepatic hemangioma and patient’s age was found (χ2=0.547, df=2, P=0.761). Nearly one-third of hemangiomas were located in the segment IV of the left hepatic lobe. There were a few complicated hemangiomas in the study sample: 2 with calcification and 1 with necrosis. The sensitivity of CT in the diagnosis of hepatic hemangioma was 76.92%; specificity, 33.3%; positive prognostic value, 83.3%; and negative prognostic value, 25.0%. The sensitivity of intravenous contrast-enhanced US in the diagnosis of hepatic hemangioma was 77.8%; specificity, 100%; positive prognostic value, 100%; and negative prognostic value, 23.1%. Conclusions. Intravenous contrast-enhanced US is more specific than intravenous contrast-enhanced CT in the diagnosis of hepatic hemangioma (P=0.0005) and has a higher positive prognostic value (P=0.001).

Published: June 2018

Gliomatosis cerebri is a rare diffusely infiltrating glial tumor involving two or more lobes and is frequently is bilateral. Infiltrative extent of tumor is out of proportion to histological and clinical features. We present a case in which finally the diagnosis of gliomatosis cerebri was made. In this case, computed tomography showed that midline structures were insignificantly shifted to the left, there was a mild dilatation of lateral ventricles more expressed on the right, and no pathologic changes of brain tissue density were found. On magnetic resonance tomography, T2W/SE and T2W/FLAIR images revealed zones of hyperintense signal, spreading with time, through several lobes of the brain with no enhancement on T1W images. Diagnosis of gliomatosis cerebri was suspected, stereotaxic biopsy was performed, and pathological examination revealed changes typical of diffuse glial tumor. In this article, changes typical of gliomatosis cerebri seen in other radiological methods such as computed tomography, magnetic resonance spectroscopy, dynamic contrast-enhanced T2*-weighted magnetic resonance, and positron emission tomography also are discussed.

Authors: Ivanauskienė Rugilė , Kregždytė Rima , Padaiga Žilvinas
Published: June 2018

Background. Breast cancer is the most common cancer among women, comprising about 23% of all cancer types. About 1300 new cases of breast cancer are registered in Lithuania annually. During the last decade, health-related quality of life has become an important part of breast cancer treatment. Pain, fatigue, and sleep disorders are important aspects of health-related quality of life. The aim of the study was to evaluate health-related quality of life (HRQL) among patients with breast cancer in Lithuania. The main tasks were to analyze HRQL in sociodemographic and clinical aspects, and to determine symptoms that have the greatest impact on HRQL . Material and methods. A cross-sectional study was carried out in four major Lithuanian hospitals. An EORTC QLQ-C30 (version 3) questionnaire with general demographic and medical information was distributed among 318 patients. A total of 284 patients were included in the analysis. Results. The response rate was 89%. The mean age of patients was 55.9 years (SD, 10.1 years), and the mean time from diagnosis – 2.36 years (SD, 3.2 years). A greater part (65%) of the studied women lived in a family or with a partner. Women reported high level of functioning across several standardized HRQOL scales: cognitive functioning, everyday activity, and physical functioning. Fatigue and sleeping disorders were the most commonly indicated symptoms in the symptom scale. Fatigue and pain were the most important factors affecting general HRQOL. Conclusions. Our results emphasize that the general HRQOL of the studied women is fair, but poorer than that of the corresponding population in other countries. Women living in a family or partnership experienced fewer financial troubles and had higher HRQOL scores across several standardized measures compared to those who were single. Women with late stages of breast cancer felt worse and were less socially active compared to women who were diagnosed with early-stage breast cancer.
Study Protocol for a Randomized Double Blind, Placebo Controlled Trial Exploring the Effectiveness of a Micronutrient Formula in Improving Symptoms of Anxiety and Depression

Published: June 2018

Background: Anxiety and depression are conferring an increasing burden on society. Although treatments exist for both conditions, side effects, and difficulties accessing treatment prevent many people from receiving adequate assistance. Nutritional approaches have demonstrated some success in treating anxiety and depression. We plan to investigate whether a micronutrient formula, Daily Essential Nutrients, improves symptoms of anxiety and depression compared to a placebo in a community recruited sample. Methods: This will be a randomized, double blind placebo controlled study (RCT). Two hundred adults will be assigned to either a placebo or micronutrient group (placebo or Daily Essential Nutrients (DEN)) in a 1:1 ratio. Baseline data will be collected for 2 weeks, followed by 10 weeks of placebo or micronutrient intervention. Psychometrics will be used to measure progress and participant safety will be monitored weekly. Results: The primary outcome measures will be total scores on three measures of symptom severity at 10 weeks. Linear mixed modelling will be used to measure between group differences and effect sizes will be calculated using pooled mean scores and standard deviations over the course of the trial. Conclusions: If effective, micronutrients could provide an alternative treatment, with fewer barriers and adverse events than currently available treatments.
Theoretical Study of Particle Dissolution during Homogenization in Cu–Fe–P Alloy
Authors: Papaefthymiou Spyros , Bouzouni Marianthi , Gavalas Evangelos
Published: June 2018

The effect of temperature, soaking time and particle size on the dissolution of particles (Fe3P and Fe) during homogenization was simulated employing Thermocalc® and DICTRA software. The initial precipitate size was determined through metallographic evaluation on industrial as-cast Cu–Fe–P alloy. The particle sizes vary from submicron (<1 μm) up to 10 μm before the heat treatment. As homogenization temperature rises, the dissolution rate increases as well, but only on temperatures above 1273 K (1000 °C) is the rate capable of completely dissolving particles effectively. At temperatures above 1273 K (1000 °C), precipitates with sizes below 5 μm dissolve completely into the Cu matrix, while larger particles only slightly decrease their size. Particles at enriched copper areas remain undissolved and slightly increase their size which is attributed to micro segregation and the local change of equilibrium conditions. The simulation results are in agreement with homogenization trials at lab scale.
An Imperfect Alliance: Feminism and Contemporary Female Buddhist Monasticisms
Authors: Langenberg Amy Paris
Published: June 2018

This essay lays the elaborate textile of feminist discourse alongside the equally rich fabric of contemporary female Buddhist monasticisms, taking note of places the latter has pulled threads from the former, but also pointing out the ways in which female monastics lead agentive, creative, and sometimes rebellious female lives that in subtle and not so subtle ways resist the label “feminist,” or contribute a new motif or fiber to the feminist weave. Case study reports on two innovative Buddhist female communities in Malaysia and Nepal, chosen because they offer examples of innovations within the context of Buddhist female monasticism that are interestingly complex as examples of Buddhist feminist consciousness, will serve to make visible a few particular female Buddhist monastic perspectives. Respectfully called in as interlocutors and cotheorizers, the monastic persons described here offer religious perspectives on norm-following, agency, and coalition-building that expand the feminist frame.
Effects of Fire Suppression Agents and Weathering in the Analysis of Fire Debris by HS-MS eNose
Authors: Falatová Barbara , Ferreiro-González Marta , Martín-Alberca Carlos , Kačíková Danica , Galla Štefan , Palma Miguel , G. Barroso Carmelo
Published: June 2018

In arson attacks the detection of ignitable liquid residues (ILRs) at fire scenes provides key evidence since ignitable liquids, such as gasoline, are commonly used to initiate the fire. In most forensic laboratories gas chromatography-mass spectrometry is employed for the analysis of ILRs. When a fire occurs, suppression agents are used to extinguish the fire and, before the scene is investigated, the samples at the scene are subjected to a variety of processes such as weathering, which can significantly modify the chemical composition and thus lead to erroneous conclusions. In order to avoid this possibility, the application of chemometric tools that help the analyst to extract useful information from data is very advantageous. The study described here concerned the application of a headspace-mass spectrometry electronic nose (HS-MS eNose) combined with chemometric tools to determine the presence/absence of gasoline in weathered fire debris samples. The effect of applying two suppression agents (Cafoam Aquafoam AF-6 and Pyro-chem PK-80 Powder) and delays in the sampling time (from 0 to 48 h) were studied. It was found that, although the suppression systems affect the mass spectra, the HS-MS eNose in combination with suitable pattern recognition chemometric tools, such as linear discriminant analysis, is able to identify the presence of gasoline in any of the studied situations (100% correct classification).
A Novel Friendly Jamming Scheme in Industrial Crowdsensing Networks against Eavesdropping Attack
Authors: Li Xuran , Wang Qiu , Dai Hong-Ning , Wang Hao
Published: June 2018

Eavesdropping attack is one of the most serious threats in industrial crowdsensing networks. In this paper, we propose a novel anti-eavesdropping scheme by introducing friendly jammers to an industrial crowdsensing network. In particular, we establish a theoretical framework considering both the probability of eavesdropping attacks and the probability of successful transmission to evaluate the effectiveness of our scheme. Our framework takes into account various channel conditions such as path loss, Rayleigh fading, and the antenna type of friendly jammers. Our results show that using jammers in industrial crowdsensing networks can effectively reduce the eavesdropping risk while having no significant influence on legitimate communications.

Authors: Wawrosz Petr , Mihola Jiří , Kotěšovcová Jana
Published: June 2018

This article presents comprehensive typology of all possible relationships among inputs of an economic system, their productivity, and output. Each situation is given an exact name explaining how intensive and extensive factors contributes to the system development. The exact contributions of the factors can be counted by so-called dynamic intensity and extensity parameters. The article describes logic of the parameters, discusses their advantages and problems and assigns their values to the presented nomenclature of the developments. The parameters are further compared with growth accounting methods and their use is demonstrated on the development of macroeconomic system on the national economy level when it is counted how intensive and extensive parameters contribute to the Czech and German GDP development in the period 1991–2017. The analysis confirms that the parameters can be used as an alternative methods to growth accounting and that managers of any economic system should pay attention whether a system achieves positive value of the dynamic intensive parameters in long run.

Published: June 2018

Les caractères tectoniques principaux des schistes de Steige et des schistes et phyllades de Ville sont distingués. En particulier, l'analyse structurale permet d'établir les relations entre les plissements, les différentes générations de schistosités et la foliation métamorphique. A l'échelle régionale, les rapports entre les édifices structuraux des deux séries sont discutés. Ces édifices ne sont pas contemporains mais relèvent d'une tectonique différente et de plissements superposés.
Sur l'origine des minéraux micacés des altérations latéritiques. Diagenèse régressive -Minéraux en transit

Published: June 2018

Sept profils d'altération latéritique de Guyane française sont étudiés. L'analyse minéralogique et pétrographique des minéraux micacés montre leur origine résiduelle. Les minéraux micacés ne sont pas néoformés par altération superficielle, mais sont hérités des roches mères. En transit dans la zone de départ des altérations latéritiques, ce sont soit les micas primaires des roches mères, soit les séricites néoformées auparavant par diagenèse régressive.

Zur Genese des Kagenfels Granits (Nordvogesen)
Authors: Hahn-Weinheimer Paula , Propach Giselher , Raschka Helmut
Published: June 2018

Die an 70 Fundpunkten im Gebiet des Kagenfels Granits entnommenen Proben wurden petro-graphisch und geochemisch untersucht. Von den mannigfaltigen Gesteinstypen werden als wichtigste beschrieben : mittel-und feinkörniger Granit, Granophyr und Rhyolith. Charakteristisch sind Zahl und Größe der Einsprenglinge und die Füllung der zahlreichen Miarolen, aus denen sich Aussagen über Mineralabfolge und Intrusion für Granit, Granophyr und Rhyolith ableiten lassen.

Aus den normativen Mineralwerten (CIPW) und der Verteilung der Konzentrationen von K, Rb, Sr, Ti, Zr ergeben sich zwei prinzipielle Tendenzen im magmatischen Differentiationsverlauf : eine kontinuierlich granitische im W-E Zug und eine subvulkanische rhyolithische im N-S Gang des Kagenfels Granits.

Les microflores des séries paléozoïques du Ghana (Afrique occidentale) et leurs relations paléofloristiques
Authors: Bär Peter , Riegel Walter
Published: June 2018

De riches ensembles de spores et de phytoplancton ont été trouvés dans des couches paléozoïques (Accraien, Sekondien) de la région côtière du Ghana. Ils permettent de dater ces gisements de la fin du Dévonien moyen au début du Carbonifère inférieur et de les considérer comme le prolongement direct du bassin de Maranhâo (Brésil), tant du point de vue lithostratigraphique que palynologique. L'étude des flores montre des différences marquées entre le Gondwana et l'Euramérique au Dévonien moyen, une correspondance plus nette au Dévonien supérieur et finalement une identité prononcée au Carbonifère inférieur. Ceci tend à prouver l'existence de la Pangée.
Dicheiropollis etruscus, un pollen caractéristique du Crétacé inférieur afro-sudaméricain. Conséquences pour l'évaluation des unités climatiques et implications dans la dérive des continents
Authors: Jardiné Serge , Biens Pierre , Doerenkamp Antoine
Published: June 2018

The genus Dicheiropollis and its type-species D. etruscus were described by Trevisan in Neocomian sediments from Italy. They were found in Lower Cretaceous deposits on each side of the South Atlantic in the coastal basins of West Africa, Angola, Congo, Gabon and of Brazil, Reconcavo and Sergipe/Alagoas. Their occurrence in the Lower Cretaceous from Algeria is a step in their geographic distribution between South Atlantic and the Italian peninsula. D. etruscus was also found in Cambodge. It may be considered as an indicator of a climatic and botanical unit in Neocomian equatorial and tropical areas. D. etruscus is also a good stratigraphie marker ; with reference to Algeria where it was found in marine sediments, it gives a Neocomian age for the base of the lacustrine deposits of the rift which precedes the afro-southamerican drift. Its geographic distribution supports modern hypotheses about Lower Cretaceous continental areas : South America, Africa and Apulia.
Palynologie et répartition des ombellifères australes actuelles. Relations avec les géoflores tertiaires
Authors: Cerceau-Larrival Marie-Thérèse
Published: June 2018

Une étude palynologique (avec l'apport de la microscopie électronique à balayage) portant sur les genres austraux d'Ombellifères, en liaison avec leur répartition géographique actuelle, permet de dégager des idées concernant l'apparition sur les terres australes des Ombellifères. Celles-ci sont en relation soit avec la géoflore antarctique tertiaire qui couvrit, durant l'Eocène, le Continent antarctique, l'Australie, la Nouvelle-Zélande et le Sud de l'Amérique australe, soit avec la géoflore arctique tertiaire, dans le cas de genres d'Afrique du Sud fondamentalement différents. On a là un argument en faveur de la séparation, pendant le Crétacé, du bloc africain de l'Amérique du Sud et du Continent antarctique avant l'apparition de la géoflore antarctique tertiaire.

Epigénies manganésifères successives dans le gisement de Moanda (Gabon)
Authors: Weber Francis , Leclerc Jacques , Millot Georges
Published: June 2018

L'étude du gisement de Moanda, au Gabon, montre que l'accumulation minérale s'est faite au cours de l'altération météorique, par épigénies successives. La première épigénie remplace à volume constant, dans la roche mère, les carbonates triples (Mg, Ca, Mn) par le carbonate de manganèse qui cristallise en rhodochrosite. Après quoi, deux itinéraires sont possibles. Ou bien le faciès à rhodochrosite évolue au niveau de la nappe et c'est la deuxième épigénie qui remplace à volume constant le «schiste» à rhodochrosite par la manganite, puis par la pyrolusite. Ou bien le faciès à rhodochrosite évolue au-dessus de la nappe, par abaissement de celle-ci, et c'est la troisième épigénie qui remplace le «schiste» à rhodochrosite par des produits mal cristallisés voisins du cryptomélane. Les calculs et appréciations montrent que la première épigénie est responsable d'une accumulation absolue de 70 % de Mn par rapport à la roche mère, que les deuxième et troisième épigénies provoquent des redistributions et concentrations irrégulières qui peuvent doubler ou même tripler, localement, ces teneurs. Enfin, après des altérations, dissolutions et lessivages, le minerai tout -venant, ainsi naturellement enrichi par accumulation relative, atteindra les teneurs de 43 à 44 °/o en Mn. Ainsi, les épigénies successives apparaissent-elles comme les responsables de l'enrichissement absolu du gisement, avant sa concentration relative par lessivage.

Après une étude géologique et pédologique des terroirs du vignoble alsacien et la présentation des caractères distinctifs des cépages et des vins d'Alsace, les auteurs analysent quelques exemples de relations existant entre la nature du sol et la spécificité des vins. Parmi les nombreux paramètres qui conditionnent l'environnement nutritionnel d'un cépage, l'influence du substrat géologique et de son sol est mise en évidence. Ce dernier entraîne non seulement un certain ordre des maturations du raisin et du vin, mais il intervient aussi pour modifier la finesse, le corps et les divers arômes du cépage, sans oublier son influence primordiale sur la conservation et la longévité du vin.
Etude palynologique (pollen et spores) du Lutétien continental de Bouxwiller (Bas-Rhin, France)
Authors: Schuler Monique , Ollivier-Pierre Marie-Françoise
Published: June 2018

Freshwater limestones and the underlying Eocene clays and lignites were penetrated by a cored borehole drilled in the Bouxwiller area. Pollen analyses of the clays and lignites were carried out on 75 samples. The pollen diagram could be subdivided into 3 distinct vegetation periods : floral assemblage I occurs at the base of the lower sands at the Bathonian (Jurassic)/Eocene boundary, and floral assemblages II and III in the brown clays and lignites. The results indicate that the base of the Bouxwiller Formation belongs to the lower Lutetian and the lignite beds to the middle Lutetian. The floral assemblages are characterized by an abundance and variety of Pteridophyta, the progressive development of the Myricaceae and Juglandaceae, the disappearance of the Normapolles and the diversification of the whole flora. The flora clearly indicates the development of a freshwater lake phase which was followed by a swamp and bog phase, during which the climate was warm and humid.

Le socle varisque de l'Europe moyenne. Apports du magnétisme et de la gravimétrie
Authors: Edel Jean-Bernard
Published: June 2018

Interpretation of magnetic and gravity anomaly maps, derived and prolongated maps has lead to the establishment of a detailed map of the magnetic and gravimetric structure of the Rhine basement (Vosges, Rhine Graben, Black Forest) and to a larger-scale map of the Variscan basement on Central Europe (from the Paris Basin to the Franconian Jura). These maps show the characteristics of the rocks (strong or weak magnetisation ; high, average or low density) that are predominant on the upper kilometers of the basement. They enable zones and sub-zones, showing similar characteristics, to be set up and followed beneath the sedimentary cover. At outcrop these zones usually coincide with the structural zones of the Variscan chain. Some important strike-slip faults are revealed among the important structural discontinuities, such as the N 35° sinistral fault of the Upper Rhine Graben and the dextral Lalaye — Lubine — Vittel fault. These maps lead to a better understanding of the structure and formation of the Variscan chain.

Published: June 2018

Dans la boutonnière du Kerdous les relations structurales entre le socle éburnéen d'âge Protérozoïque inférieur et sa couverture épicontinentale du début du Protérozoïque supérieur indiquent l'existence de cisaillements crustaux compatibles avec l'évolution géodynamique pan-africaine sur le bord nord du craton ouest-africain. La faille ductile pluri-kilométrique des Ameln, par laquelle un compartiment de socle se déverse vers le Nord sur sa couverture quartzitique, en est un exemple. Ses mylonites à quartz ou à quartz et feldspaths ont fait l'objet d'une étude pétrostructurale qualitative et quantitative. La déformation se place dans le domaine légèrement constrictif, proche de la déformation plane. Bile associe des mécanismes continus et des mécanismes discontinus dans un régime cisaillant.
Stromatolites et hauts niveaux lacustres pléistocènes du bassin Natron-Magadi (Tanzanie-Kenya). Pleistocene stromatolites and high lake levels of the Natron-Magadi basin (Tanzania-Kenya)
Authors: Casanova Joel
Published: June 2018

Au cours d'épisodes humides récents, des stromatolites se sont formés en bordure d'un paléolac, dont le rivage se situe 60 m au-dessus du niveau actuel des lacs Natron et Magadi. Trois générations de stromatolites sont décrites, les plus récentes encroûtant généralement les formes érodées plus anciennes. Elles correspondent à trois hauts niveaux lacustres différents, dont les âges se distribuent du Pléistocène moyen à l'Holocène. Les stromatolites recouvrent l'ensemble des substrats durs, parmi lesquels figurent de nombreux supports végétaux. Oncolites, encroûtements plans et cylindriques, ainsi que diverses formes de bioherms sont les principales morphologies rencontrées. Une analyse pétrographique et morphologique détaillée a permis d'établir une zonation littorale précise. Les principaux facteurs de l'environnement, tels que la profondeur, l'hydrodynamisme ou l'intensité lumineuse, influencent directement la morphologie des stromatolites. La phase carbonatée est de la calcite précipitée conjointement par des cyanophycées et des bactéries sous forme de tapis ou de colonies. La microstructure la plus fréquente résulte de la répétition d'un doublet composé d'une lamine sombre micritique et d'une lamine claire sparitique. Ce doublet représente un cycle écologique de la croisance du tapis microbien ; il est interprété en termes de contraste saisonnier.

La faune pléistocène des dépôts de la Peninj à l'Ouest du lac Natron (Tanzanie) est écologiquement semblable à celle d'Olduvai. Dans la partie moyenne de la série («Middle Zone »), le milieu était ouvert et sec ; au-dessus, dans les «Upper Sandy Clays » (avec le site archéologique de Kipalagu), les espèces aquatiques sont très communes. Les comparaisons biostratigraphiques basées sur les éléphants, les suidés, les antilopes, les rhinocéros, les hyènes, suggèrent que l'ensemble de la formation Humbu doit être corrélée avec la zone à Metridiochoerus compactus de Koobi Fora ; que les «Upper Sandy Clays » (avec la plupart des sites archéologiques) pourraient être aussi récents que le «Bed III » d'Olduvai, et qu'il est très improbable que les Lower Sandy Clays (avec Australopithecus boisei ) soient plus anciens que le «Middle Bed II » d'Olduvai.
La distribution des bauxites sur le craton ouest-africain. Distribution of bauxites on the West African Craton
Authors: Boulanger Bruno , Millot Georges
Published: June 2018

Earlier lateritic bauxites studies allow us to distinguish original weathering facies and derived degradation facies. The distribution of these facies is not just of any kind. In the landscape, this stepped arrangement is to be related with mechanisms of geochemical planation. According to the scale of the West Africa Craton, the altitudinal differences of ore deposits account for the upthrust of the craton during the Tertiary.

Nous tentons dans cette synthèse de rassembler l'essentiel des données généralement admises concernant la stratigraphie, le magmatisme, le métamorphisme et la tectonique du Massif Armoricain. Ces données montrent que le socle armoricain représente l'héritage d'une longue évolution dont les témoins les plus anciens ont un âge voisin de 2000 Ma et qui s'achève il y a environ 280 Ma. On y distingue des événements précambriens (2200-540 Ma) marqués par l'orogenèse cadomienne fini-protérozoïque (620 à 540 Ma) et des événements paléozoïques (540-280 Ma) marqués par l'orogenèse varisque au sens large (440 à 290 Ma). Ces événements sont intégrés dans des modèles géodynamiques encore incomplets mais permettant de souligner la cohérence des données. La superposition de ces deux histoires détermine les caractéristiques actuelles du Massif Armoricain : zone orogénique ancienne où les témoins sédimentaires précambriens et paléozoïques sont encore présents, mais où les roches d'origine plus profonde (granitoïdes, métamorphites) restent le trait dominant.
Les massifs cristallins externes des Alpes occidentales françaises, un fragment de la zone interne varisque / The external crystalline massifs of the French western Alps, a part of the internal variscan zone

The external crystalline massifs of the French western Alps, a part of the internal variscan zone.

The external crystalline massifs (ECM) have undergone a polycyclic orogenic evolution.

After Liassic rifting which mainly concerns the Haut-Dauphiné (Pelvoux) and the southern part of Belledonne, the ECM, external basement of the alpine chain, underwent several periods of deformations as well as a weak metamorphism. The main phase of deformation begins at the limit between the Late Oligocene and the Early Miocene. During this period, the ECM have been thrust towards the external part of the chain, but their general arcuate disposition was not fundamentally modified. This arcuate structure is inherited from the Variscan orogeny, the evolution of which is still decipherable, notwithstanding the Alpine orogeny.

The Variscan evolution of the ECM, after a rifting stage in Cambrian times marked by both acid and basic intrusions, is characterized by several stages. The earliest stage is an high pressure-high temperature (HP/HT) stage, represented by an eclogitic and a less frequent granulitic facies metamorphism. Ordovician to Silurian in age, this metamorphism mainly affects supracrustal material. This was followed by crustal thrusting intra-Devonian in age, synchronous with a Barrovian synmigmatitic metamorphism which was followed by a partial to complete verticalization of the thrust pile, the metamorphic grade being unchanged.

The evolution up to this stage, concerns the whole of the ECM with the exception of the south-western part of the Belledonne massif, in which the first thrusts are Dinantian in age. They include a fragment of Cambrian oceanic crust and are linked to an epizonal to mesozonal metamorphic event. In the other massifs, epizonal strike-slip faults are synchronous with these thrusts. Following this last stage and before the intrusion of late orogenic granites, at about 300-320 Ma, the majority of the massifs have been locally reworked by a high temperature-low pressure (HT-LP) mobilization, essentially postkinematic.

The tectonic and metamorphic evolution of the ECM closely resembles that of the French Massif Central. In consequence the ECM form can be considered as a part of the French variscan chain.
A visible-light-controlled platform for prolonged drug release based on Ag-doped TiO2 nanotubes with a hydrophobic layer
Authors: Liang Caihong , Wen Jiang , Liao Xiaoming
Published: June 2018

In this work, a visible-light-controlled drug release platform was constructed for localized and prolonged drug release based on two-layer titania nanotubes (TNTs) fabricated using by an in situ voltage up-anodization process. The visible-light photocatalytic activity is improved by loading Ag onto the TNTs by NaBH4 reduction. Then, the TNTs containing Ag nanoparticles were modified with dodecanethiol (NDM) to create a hydrophobic layer. To demonstrate the visible-light-controlled drug release, the Zn2+ release behavior of the samples was investigated. In the initial 12 h, TNTs without NDM displayed a faster release rate with 29.4% Zn2+ release, which was more than three times that of the TNTs with NDM (8.7% Zn2+ release). Upon visible-light illumination, drug release from the sample coated with NDM was shown to increase due to the photocatalytic decomposition of NDM. The amount of released Zn2+ for this sample increased up to 71.9% within 12 h, indicating visible-light-controlled drug release. This drug release system may exhibit promising application as a localized, prolonged drug delivery platform.
A Stealth CME Bracketed between Slow and Fast Wind Producing Unexpected Geoeffectiveness

Published: June 2018

We investigate how a weak coronal mass ejection (CME) launched on 2016 October 8 without obvious signatures in the low corona produced a relatively intense geomagnetic storm. Remote sensing observations from SDO, STEREO, and SOHO and in situ measurements from Wind are employed to track the CME from the Sun to the Earth. Using a graduated cylindrical shell model, we estimate the propagation direction and the morphology of the CME near the Sun. CME kinematics are determined from the wide-angle imaging observations of STEREO A and are used to predict the CME arrival time and speed at the Earth. We compare ENLIL MHD simulation results with in situ measurements to illustrate the background solar wind where the CME was propagating. We also apply a Grad–Shafranov technique to reconstruct the flux-rope structure from in situ measurements in order to understand the geoeffectiveness associated with the CME magnetic field structure. Key results are obtained concerning how a weak CME can generate a relatively intense geomagnetic storm: (1) there were coronal holes at low latitudes, which could produce high speed streams (HSSs) to interact with the CME in interplanetary space; (2) the CME was bracketed between a slow wind ahead and an HSS behind, which enhanced the southward magnetic field inside the CME and gave rise to the unexpected geomagnetic storm.
A review of the assassin-fly genus Laphyctis Loew, 1858 with descriptions of two new species (Diptera, Asilidae, Laphriinae)
Authors: Londt Jason G. H. , Dikow Torsten
Published: June 2018

The asilid genus Laphyctis Loew, 1858 is revised. The genus is restricted to the Afrotropical Region where it has been confused with the more widely distributed Laphystia Loew, 1847, which currently has no Afrotropical representatives. Three previously described species are recognised: Laphyctisgigantella (Loew, 1852), type of the genus, Laphyctisargenteofasciata (Engel, 1929), reinstated from the synonymy of L.gigantella, and Laphyctisorichalcea (Lindner, 1973). Two new species are described, Laphyctiseremia sp. n. from Namibia and Laphyctisiota sp. n. from South Africa. The genus has a wide distribution ranging from northern Kenya to eastern South Africa and to western Namibia. Species are associated with dry, sandy habitats.
"Look what they've done to our data!" — How Aggregators Change Data Items in Collection Records
Authors: Mesibov Robert
Published: June 2018

Aggregators such as the Atlas of Living Australia (ALA) and the Global Biodiversity Information Facility (GBIF) have recently been criticised for imposing "backbone taxonomies" on records provided by museums, herbaria and other sources. Taxon names may be changed to suit the backbone, with the result that the taxon rank of the record may change and the originally provided name may no longer be searchable online through the aggregator.

Aggregators may also delete data items, either by omitting entire fields or rejecting data items not conforming to aggregator-specific data standards. Modifications are more common than deletions and are particularly worrying in geospatial, date and recorder data fields. It can be difficult to locate originally provided data on aggregator websites, even for individual records, and bulk downloads from aggregators typically mask the changes made.

In this presentation I document the loss and modification of biodiversity data items by aggregators and suggest strategies for museums and herbaria to counter data loss and modification.
Unmounted Doesn’t Mean Unprocessed: A Case Study of Exporting Australian Herbarium Specimens
Authors: Hirst Sarah , Jobson Peter
Published: June 2018

In 2017, two incoming international herbarium loans were confiscated and destroyed by the Commonwealth Department of Agriculture and Water Resources (DAWR). Following these regrettable incidents, communication has improved between Managers of Australasian Herbarium Collections (MAHC) and Plant Import Operations Branch of DAWR. The outcome is that new protocols now exist for shipment of plant material between herbaria based on the recognition by DAWR that all herbarium specimens are in fact processed (pressed, dried and frozen) even if they are not fully mounted (Brown et al, this conference). Simultaneously, the United States Department of Agriculture (USDA) had been reported to be destroying incoming unmounted specimens, thus making it difficult to send unmounted exchange material overseas, and particularly to the USA.

Using the documentation developed for incoming overseas loans by MAHC and, encouraging the receiving institution in the USA to acquire a USDA 588 Importing Permit for unprocessed plant specimens (non-loan, unmounted herbarium specimens), it was possible to export unmounted herbarium specimens and dried DNA samples into the USA. Excluding the USA specific requirements, we were also able to export exchange material and dried DNA samples to Singapore and Sweden.
Books and Drawers full of Moths

The Otago Museum houses one of New Zealand’s largest Lepidoptera collections that consists of more than 31,000 macro moth specimens collected across New Zealand over the last 30 years. Alongside this collection, supplementary information is found in detailed field notebooks that cover, for most sites, the total abundance of the different species present in these samples. We have been able to use the notebooks to work out the sampling intensity and sites to map both the collections and the abundances to some degree.

It is impractical to collect everything. As a result, the common species are left out of collections and the rare and unusual sightings fill the collections. When planning to resample collecting sites to investigate changes in ecosystems, just relying on collections for species presence and absence would skew the results. It should also be noted that field notebooks are not a panacea for biological information as the information in them ages, so too can the reliability and accuracy of the notes within.

Here we discuss how the field notebook data compares with the information accompanying the specimens housed within the museum collection. This is a recently digitised collection and allows an insight into the collectors sampling, vouchering and data practices and how these can affect modern interpretation and variation in repeat sampling.

A molecular phylogeny of the Neotropical snail-eating snakes (tribe Dipsadini) is presented including 43 (24 for the first time) of the 77 species, sampled for both nuclear and mitochondrial genes. Morphological and phylogenetic support was found for four new species of Dipsas and one of Sibon, which are described here based on their unique combination of molecular, meristic, and color pattern characteristics. Sibynomorphus is designated as a junior subjective synonym of Dipsas. Dipsaslatifrontalis and D.palmeri are resurrected from the synonymy of D.peruana. Dipsaslatifasciata is transferred from the synonymy of D.peruana to the synonymy of D.palmeri. A new name, D.jamespetersi, is erected for the taxon currently known as Sibynomorphuspetersi. Re-descriptions of D.latifrontalis and D.peruana are presented, as well as the first photographic voucher of an adult specimen of D.latifrontalis, along with photographs of all known Ecuadorian Dipsadini species. The first country record of D.variegata in Ecuador is provided and D.oligozonata removed from the list of Peruvian herpetofauna. With these changes, the number of Dipsadini reported in Ecuador increases to 22, 18 species of Dipsas and four of Sibon.
