Abstract. Straightforward communication of monitoring results is of major importance in emergency scenarios relevant to large slope instabilities. Here we describe the communication strategy developed for the Mont de La Saxe rockslide threatening La Palud and Entrèves hamlets in the Courmayeur municipality (Aosta Valley, Italy). Starting from the definition of actions and needs of the landslide management team, including scientists, technicians, civil protection operators, decision makers, and politicians, we show that sharing and disseminating ad hoc information simplifies the understanding of the landslide evolution, as well as the correct communication of the level of criticality.

Photogrammetry has been used since long to periodically control the evolution of landslides; however, true monitoring is reserved to robotic total stations and ground based InSAR systems, capable of high frequency, high accurate 24h/day response. This paper presents the first results of a fixed terrestrial stereo photogrammetric system developed to monitor shape changes of the scene. The system is made of two reflex cameras, each contained in a sealed box with a control computer that periodically acquires an image and send it to a host computer; once an image pair is received from the two cameras, the DSM of the scene is generated by image correlation and made available for archiving or analysis. The system has been installed and is being tested on the Mont de la Saxe landslide, where several monitoring system are active. Some instability of the camera attitude has been noticed and is corrected with an automated procedure. First comparisons with InSAR data show a good agreement.

Full textAbstract:
In this paper, the results of preparation of material for adsorption of aflatoxin B1, based on modification of montmorillonite with copper ions (Cu-MONT), are presented. The bentonite clay from Sokolac deposit (Sipovo, Bosnia) was used as the starting raw material. After modification of concentrate of montmorillonite (MONT) with copper, the content of copper in Cu-MONT, was 2.65%. It was shown that MONT, as well as the Cu-MONT were efficient in adsorption of aflatoxin B1, at different mass ratios of adsorbent : toxin, and at different pH values. It was determined that for MONT, at the mass ratio adsorbent : toxin = 5000 : 1, aflatoxin B1 adsorption index was 100% at pH 3, 98% at pH 7 and 96% at pH 9. For Cu-MONT, at the same mass ratio, the following aflatoxin B1 adsorption indexes were achieved: 98% at pH 3, 98% at pH 7 and 96% at pH 9. No differences in adsorption of this toxin by both montmorillonites with decreasing the mass ratio of adsorbent : toxin (250 : 1) were observed. That means that ion exchange of inorganic cations in montmorillonite with copper ions did not cause any changes in aflatoxin B1 adsorption, at pH 3, as well as at pH 7 and 9. It was also noticed that adsorption of aflatoxin B1 by MONT and Cu-MONT was not pH dependent.

Full textAbstract:
Mont Ross is the main volcanic feature of the Kerguelen Archipelago (terres Australes et Antarctiques françaises). This newly formed volcano buildup over 2 Ma provides us with an outstanding model of volcanism occurring on an intraplate structure already aged 40 Ma. Mont Ross is the subaerial part of a plutonic complex located in Galliéni Peninsula. From seismic refraction studies, P-wave velocities within the upper crust range downward from 5.35 km/s at sea level to 6.60 km/s at a depth of 11 km. These are definitely higher than those encountered within surrounding basalts known as plateau basalts. These high velocities reveal, at first glance, an origin and composition of the basement of Mont Ross far distinct from those of tholeiitic or transitional lava flows generated near spreading centres. By comparison with plutonic ring complexes, it is reasonable to state that monzonite and syenite are the basic materials of the basement. Seismic velocities (6.85 to 7.30–7.35 km/s) and related Poisson ratio (σ = 0.30) within lower crust are consistent with gabbros as prominent material. The thickness of the lower crust below Mont Ross (6–7 km) is roughly the same as that below the archipelago. Gabbros are exposed around several plutonic ring complexes spread over the archipelago. The transition to mantle might be modelled by a 2 km thick transition zone, with high velocity gradient, already noticed below the archipelago. Velocities of 7.30–7.35 km/s at the base of the crust below Mont Ross do not preclude contamination of the lower crust by mantle material. Both gravity and seismic data substantiate the occurrence of high density (velocity) within the upper crust below Mont Ross. Isostatic compensation of Mont Ross is rather achieved by a flexural deflection of the lithosphere than by an Airy-type model. The structures of Mont Ross and Hawaiian volcanoes bear analogies likely related to their intraplate genesis.

We examine how the territorialisationprocess of economic development in Val de Saône as the implication of the creation of The ChevènementAct. As a result, we found that the territorialisation is a kind of adaptation to the Chevènement Actenforcement related to the authority of Urban Community of Grand Lyon and Association betweenregions of Saône Mont d’Or (Syndicat de Communes Saône Mont d’Or) in economic development in Valde Saône.

Full textAbstract:
Abstract Three-factor and three-level tests were carried out by Box–Behnken response surface methodology, with amoxicillin as the target pollutant, nanometer zero-valent iron (nZVI) materials loaded with montmorillonite prepared by liquid phase reduction method and the concentration of FeSO4 and NaBH4 and montmorillonite dosage as influencing factors. It revealed that the interaction between FeSO4 concentration and NaBH4 concentration had a significant effect on the preparation of montmorillonite-loaded nanometer zero-valent iron material, playing a key role in the removal of amoxicillin, and the effect of FeSO4 concentration was even more significant. In addition, the shape, structure and characteristic groups of the prepared materials were analyzed by means of scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), etc. The nanometer zero-valent iron loaded with montmorillonite can effectively slow down the nZVI agglomeration effect and improve the effect of material degradation of pollutants. For the same concentration of amoxicillin wastewater, the removal rate of amoxicillin wastewater, after 1 h reaction, is as follows: Mont/nZVI > nZVI > Mont. The optimal conditions for the reaction are: pH is 3, the initial concentration is 60 mg/L, and the dosage is 2 g/L. The higher the temperature, the more amoxicillin is degraded by Mont/nZVI.

Full textAbstract:
Background. The pathogenesis of abdominal aortic aneurysm (AAA) is characterized by atherosclerosis with chronic inflammation in the aortic wall. Montelukast is a selective cys-LT 1 receptor antagonist that can suppress atherosclerotic diseases. We evaluated the in vitro properties of montelukast and its in vivo activities in an angiotensin II–infused apolipoprotein E–deficient (apoE−/−) AAA mouse model. Methods. The mouse monocyte/macrophage cell line J774A.1 was used in vitro. M1 macrophages were treated with montelukast, and gene expressions of inflammatory cytokines were measured. Macrophages were cultured with montelukast, then gene expressions of arginase-1 and IL (interleukin)-10 were assessed by quantitative polymerase chain reaction, arginase-1 was measured by fluorescence-activated cell sorting, and IL-10 concentration was analyzed by enzyme-linked immunosorbent assay. In vivo, one group (Mont, n=7) received oral montelukast (10 mg/kg/day) for 28 days, and the other group (Saline, n=7) was given normal Saline as a control for the same period. Aortic diameters, activities of matrix metalloproteinases (MMPs), cytokine concentrations, and the number of M2 macrophages were analyzed. Results. Relative to control, montelukast significantly suppressed gene expressions of MMP-2, MMP-9, and IL-1β, induced gene expressions of arginase-1 and IL-10, enhanced the expression of the arginase-1 cell surface protein, and increased the protein concentration of IL-10. In vivo, montelukast significantly decreased aortic expansion (Saline vs Mont; 2.44 ± 0.15 mm vs 1.59 ± 0.20 mm, P<.01), reduced MMP-2 activity (Saline vs Mont; 1240 μM vs 755 μM, P<.05), and induced infiltration of M2 macrophages (Saline vs Mont; 7.51 % vs 14.7 %, P<.05). Conclusion. Montelukast induces M2 macrophage polarization and prevents AAA formation in apoE−/− mice.

Full textAbstract:
The later prehistoric rock-engravings of Mont Bégo, in the Maritime Alps on the French–Italian border, provide a rare possibility of grasping the meaning of a group in prehistoric art. Two elements in their limited repertoire of forms are daggers and halberds, which also occur as physical objects or as images in the contemporary sites of adjacent north Italy; their contexts show they are, in that area, associated with the status of adult males in society. That same interpretation is applied to the Mont Bégo figures, and this is found congruent with other motifs — especially ploughs and cattle — in the repertoire. It may explain also the other common motif, a geometrical form interpreted as a map of a prehistoric farmstead, by associating it with plough agriculture and land division. The insights developed from the study for what ‘meaning’ amounts to in the study of prehistory are set down.

Full textAbstract:
U–Pb data provide new constraints on the age of sedimentation, metamorphism, magmatism, and deformation in the Grenville Province of western Quebec. A metapelite, an alaskitic gneiss, and an amphibolite were sampled within an area of 1 km2 in the Mont-Laurier terrane. The metapelite yielded detrital-metamorphic zircons that gave 207Pb/206Pb ages of ca. 1205–2200 Ma. The youngest detrital components, between 1210 and 1300 Ma and possibly as old as [Formula: see text] Ma, provide a maximum age range for the deposition of this rock. Data for the alaskitic gneiss suggest that it is either derived from an igneous (volcanic) protolith with a minimum age of ca. 1250 Ma and a maximum age of [Formula: see text] Ma, or is a dyke emplaced at ca. 1140–1170 Ma. The amphibolite yielded zircon interpreted as metamorphic, with a minimum age of 1118 Ma, and a maximum age not likely older than ca. 1160 Ma. Zircons from charnockites and monzonites of the Morin plutonic complex gave zircon igneous ages between ca. 1157 and 1165 Ma. High-grade metapelites of the Réservoir Cabonga terrane yielded metamorphic zircon ages of 1140-1160 Ma. Metamorphic monazites from both the Réservoir Cabonga and the Mont-Laurier terranes yielded ages of 1138−1182 Ma, interpreted as the crystallization age or the time that significant Pb loss ceased. These ages indicate that the two terranes underwent the same long-lasting metamorphic event. The overlap between ages of metamorphic zircons and monazites on the one hand and the age of anorthosite–charnockite magmatism on the other hand suggests a long-lasting high-grade metamorphism with heat contribution from crystallizing plutons. A posttectonic aplite dyke from the interior of the Mont-Laurier terrane gives a zircon minimum age of 1054 Ma, considered a minimum age for penetrative deformation in this part of the Grenville Province. Rutile ages of 945–955 Ma record cooling through about 400 °C in both the Réservoir Cabonga and the Mont-Laurier terranes.

Full textAbstract:
Snow gliding, a slow movement downhill of snow cover, is complex to forecast and model and yet is extremely important, because it drives snowpack dynamics in the pre-avalanching phase. Despite recent interest in this process and the development of some studies therein, this phenomenon is poorly understood and represents a major point of uncertainty for avalanche forecasting. This study presents a data-driven, physically based, time-dependent 1D model, Poli-Glide, able to predict the slow movement of snowpacks along a flow line at the daily scale. The objective of the work was to create a useful snow gliding model, requiring few, relatively easily available input data, by (i) modeling snowpack evolution from measured precipitation and air temperature, (ii) evaluating the rate and extent of movement of the snowpack in the gliding phase, and (iii) assessing fracture (i.e., avalanching) timing. Such a model could be then used to provide hazard assessment in areas subject to gliding, thereby, and subsequent avalanching. To do so, some simplifying assumptions were introduced, namely that (i) negligible traction stress occurs within soil, (ii) water percolation into snow occurs at a fixed rate, and (iii) the micro topography of soil is schematized according to a sinusoidal function in the absence of soil erosion. The proposed model was then applied to the “Torrent des Marais-Mont de La Saxe” site in Aosta Valley, monitored during the winters of 2010 and 2011, featuring different weather conditions. The results showed an acceptable capacity of the model to reproduce snowpack deformation patterns and the final snowpack’s displacement. Correlation analysis based upon observed glide rates further confirmed dependence against the chosen variables, thus witnessing the goodness of the model. The results could be a valuable starting point for future research aimed at including more complex parameterizations of the different processes that affect gliding.

Full textAbstract:
At the surface, Mont Mégantic, the easternmost and most imposing of the Monteregian hills, is composed of 77.5% leucogranite and syenite and 22.5% gabbro. Nonetheless, the intrusion is characterized by a major positive Bouguer anomaly of +20 mGal. A computed three-dimensional gravity adumbration is consonant with the intrusion having the form of a vertical prismatic column with a flat base at a depth of 10 km. The base appears to coincide with the unconformity atop Precambrian basement rocks. Gabbro composes 96% of the adumbration. Leucogranite and syenite make up the remainder and are confined to an uppermost layer no more than about 1 km thick. The subvolcanic texture of the granite and presence of miarolitic cavities at Mégantic show the shallow level of the intrusion, the present surface perhaps having been no deeper than 1 or 2 km. This is the same as the depth of emplacement elucidated at Mont Royal, at the opposite end of the Monteregian chain, which in turn points to uniform uplift and erosion since Early Cretaceous time across the entire area, from the shield and well into the Appalachians. The mechanism of intrusion at Mégantic appears to be the same as that we proposed earlier for the eight classical Monteregians.

Full textAbstract:
Lentinus squarrosulus is a popular mushroom in Nigeria used for traditional medicine apart from food. The identification of those high-quality fungal species is not only necessary but has great economic significance as it will allow product distributors to verify the material they are selling. Hence, this study investigated the morphological and molecular relationship among L. squarrosulus samples from different locations in Ibadan. Ten samples of L. squarrosulus were collected from nine different natural habitats in Ibadan, Oyo State, Nigeria, from which pure cultures were prepared. Isolation of DNA was done from fruiting bodies of fresh samples evaluated. Ten primers were designed from ITS sequences of the Family Agariceae and used for the study. The ten mushrooms evaluated in the study showed diverse morphological features such as colour of cap and pileus, size of stipe and pileus. A total of 50 amplicons were generated of which 31 bands (62%) were polymorphic. The RAPD variety-specific products were generated in some of the genotypes evaluated which can serve as unique identifiers. The study showed mean values for marker gene diversity of 0.27, Polymorphism Information Content (PIC) of 0.25 and 63.81% polymorphism. Both morphological and molecular analyses revealed two clustered groups. Number and types of samples in each group were not the same in both studies. The presence of unique band pattern among sampled fungi evaluated showed the discriminating power of the primer Ast-F in the study.

Some of the effects of aging and inactivity can be confounded. Master athletes are an interesting model to investigate human aging as they are free from the deleterious effects of inactivity. The aim of the present study was to analyze the number of male finishers and their performance across age at the Ultra-Trail du Mont-Blanc® (UTMB®, 170 km, 10 000 m of elevation gain) and two shorter races organized during the same event, Courmayeur-Champex-Chamonix (CCC®, 101 km, 6100 m) and Orsières-Champex-Chamonix (OCC, 55 km, 3500 m). Eighty percent of the finishers were aged between 23 and 49 years when considering the three races together. Top 10 average speed progressively decreased with age independently of the distance of the race. For every competition, average speed for the Top 10 decreased by 10% between 23–39 yr and 40–49 yr, then by 20% per decade. Future interventional studies should investigate the physiological factors (e.g. neuromuscular fatigue) associated with the age-related decline in ultra-trail running performance.

Full textAbstract:
A common feature of Cherubini's Parisian operas of the 1790s is the displacement of one or more of the protagonists. They are out of sorts with their environment, experiencing a need to escape that prevents the traditional unity of place from focusing the drama. The heroine ofLodoïska(1791)isimprisoned in a tower; inEliza ou le Voyage aux glaciers du Mont St BernardFlorindo travels to Mont St Bernard to forget his beloved Eliza, who pursues him and saves him from suicide. For the heroine ofMédée(1797), Corinth represents unhappiness: she returns to her former home only to take revenge. InLes deux Journées(1800), Armand and Constance flee Paris to save their lives; even in the comic operaL'Hôtellerie portugaise(1798) the central location serves merely as a rendez-vous for the two lovers on their way to evade the wicked plans of Donna Gabriele's stepfather. These operas do not, in other words, unfold in reassuring environments where characters feel at home; nor are there neutral backgrounds that enable the drama to concentrate on personal interaction. What is more, although placing protagonists in such unhappy circumstances is widespread in late eighteenth-century opera, and ‘rescue operas’ in particular, it is at least arguable that Cherubini exploited their restlessness in a uniquely successful manner.

Full textAbstract:
At a ten-year mark, a verse written by Virgil (Aen. 1.291) looks like a longexpected answer to his friend Horace, who had in turn alluded to a Virgil’s poem in epod. 16. During the hundred-year-old discussion about the relationships between eclogue 4 and epode 16, the stylistic element known as "motto" has seemed conclusive to determine the precedence of Virgil’s poem on Horace’s one. At different stages, Alberto Cavarzere argued that Hor. epod. 16.1 was an answer to Verg. ecl. 4.4. In my opinion, the same rhetoric device was used about ten years later by Virgil, answering in turn to Horace’s "motto". As a conclusion, we can indeed relate Hor. epod. 16.1 and Verg. Aen. 1.291, since from several points of view (content, context, style, metric features) Virgil’s verse seems to continue the alexandrine dialogue engaged ten years before by Horace’s epode.

Full textAbstract:
A chemical analysis of the polyphenolic patterns of diploid and tetraploid populations of Lotus corniculatus s.l. (Fabaceae) growing in the southern French Alps showed that diploids from Mont Ventoux and from Montagne de Lure belong to the same chemotype. On the other hand, tetraploids showed two different chemotypes. This paper suggests the following hypothesis about the evolution of Lotus corniculatus in this area since the last glaciation: diploids could be derived from a relic diploid population scattered by glaciation and restricted within very narrow areas, whereas the tetraploids originating from the diiploids were more competitive and radiated into larger areas cleared from ice. Key words: Lotus corniculatus, birdsfoot trefoil, Fabaceae, polyploidy, polyphenolic metabolism, evolution.

Full textAbstract:
Mont Saint Hilaire is an approximately 10 km2 alkaline plutonic complex in the Monteregian petrographic province of Quebec. The complex consists of an older, western half of alkali gabbros and an eastern portion of nepheline syenites and magmatic breccias. The intrusives were emplaced at depths of no more than a few kilometres into Paleozoic sedimentary rocks through the underlying Grenville basement. 40Ar/39Ar analyses of amphibole yield complex age spectra in which the apparent ages decrease with increasing heating temperature. Conventional K–Ar analyses of amphibole, pyroxene, and feldspar yield anomalously old dates. These data indicate the presence of small yet significant amounts (up to 8 × 10−11 mol/g) of excess 40Ar. The quantities of excess argon are variable between rocks and minerals from the same rock. In contrast, biotites yield concordant plateaus and consistent ages ranging only from 124.1 to 124.6 Ma. These data define the age of the complex (124.4 ± 1.2 Ma) and imply a short time span of emplacement of about 0.5 Ma or less. The restricted time interval suggests the various lithologies are cogenetic. The nature of the amphibole 40Ar/39Ar spectra indicates that excess 40Ar was acquired after crystallization. The 40Ar could have been present in the initial magma either from crustal assimilation or from a mantle source. Alternatively, it could have been derived from outgassing of older crustal rocks. The occurrence of excess 40Ar in epizonal plutons may be a more widespread phenomenon than commonly recognized.

Eryngium palmatum was described by Roberto de Visiani and Josif Pančić in Plantae serbicae rariores aut novae (1870: 20). Wörz (2010) stated that, although the original description is from 1870, Pančić recorded E. tricuspidatum Linnaeus (1753: 8) eleven years earlier with the same localities that Visiani and he cited in the protologue for E. palmatum. In fact, Pančić reported E. tricuspidatum already in 1856: 520, for the following localities: “bei Ravanita, Sv. Petka im Cupriaer, Banja im Aleksinacer, Ugljarevo im Kragujevacer“. Describing the new species E. palmatum in 1870, Visiani and Pančić cited all the previously mentioned localities with the addition of mt. Ogradjenik: “Hab. in saxosis calcareis prope Ravanica, Sv. Petka in circ. Cupria, ad Banja circ. Aleksinac, Uljarevo circ. Kragujevac, et mont. Ogradjenak Serbiae meridionalis”.

Abstract. Diffusion properties of cosmogenic 3He in quartz at Earth surface temperatures offer the potential to directly reconstruct the evolution of past in situ temperatures from formerly glaciated areas, which is important information for improving our understanding of glacier–climate interactions. In this study, we apply cosmogenic 3He paleothermometry to rock surfaces gradually exposed from the Last Glacial Maximum (LGM) to the Holocene period along two deglaciation profiles in the European Alps (Mont Blanc and Aar massifs). Laboratory experiments conducted on one representative sample per site indicate significant differences in 3He diffusion kinetics between the two sites, with quasi-linear Arrhenius behavior observed in quartz from the Mont Blanc site and complex Arrhenius behavior observed in quartz from the Aar site, which we interpret to indicate the presence of multiple diffusion domains (MDD). Assuming the same diffusion kinetics apply to all quartz samples along each profile, forward model simulations indicate that the cosmogenic 3He abundance in all the investigated samples should be at equilibrium with present-day temperature conditions. However, measured cosmogenic 3He concentrations in samples exposed since before the Holocene indicate an apparent 3He thermal signal significantly colder than today. This observed 3He thermal signal cannot be explained with a realistic post-LGM mean annual temperature evolution in the European Alps at the study sites. One hypothesis is that the diffusion kinetics and MDD model applied may not provide sufficiently accurate, quantitative paleo-temperature estimates in these samples; thus, while a pre-Holocene 3He thermal signal is indeed preserved in the quartz, the helium diffusivity would be lower at Alpine surface temperatures than our diffusion models predict. Alternatively, if the modeled helium diffusion kinetics is accurate, the observed 3He abundances may reflect a complex geomorphic and/or paleoclimatic evolution, with much more recent ground temperature changes associated with the degradation of alpine permafrost.

Cette étude propose de réévaluer la Comédie de Mont-de-Marsan, chef-d’œuvre du théâtre profane de Marguerite de Navarre, en se concentrant moins sur le contenu idéologique de la pièce que sur son vocabulaire et son interpellation du spectateur. En traçant le champ lexical du jugement à travers les personnages de la Supersticieuse et la Sage, elle démontre la façon dont la Comédie met en scène l'interdiction biblique de juger son prochain et la difficulté d'obéir à cette interdiction. Le jugement se révèle réflexif: en jugeant le comportement des autres ou même en leur reprochant ce jugement, la Supersticieuse et la Sage se condamnent et témoignent de l'incapacité de l’être humain à gagner le salut par l'adhésion à la doctrine. Le spectateur, invité à juger dès le début de la pièce, est amené à se voir dans ces personnages et à reconnaître sa propre tendance pécheresse à juger.

The use of meta-models approach as component of the prevention strategy against different pathogens attack, specific for vegetal cultures, receives an increasing interest. Due to the importance of the climatic influence upon pathogens action, almost all these approaches use the inputs from meteorological stations placed in field. Another important component of such a system is represented by a specific software program used for estimation of virtual geographical distribution of target pathogen/pathogens. This article aims to emphasize the possibility of using the meta-models for predicting Phytophtora infestans Mont. de Bary attack. The research was carried on during spring - autumn 2012 in a potato field located in Jucu village, on the experimental field of the UASMV Cluj - Napoca. Climatic conditions (temperature and rainfall regimen) and attack degree were monitored using a meteorological station placed on the field, and observations. Rainfall regimen and average daily temperature were taken into consideration, in approaching the multiregression model with tow inputs. The statistical data processing was performed with STATISTICA 7.0 v. programme. The analysis of variance (ANOVA) applied to the interaction between attack degree of Phytophthora infestans Mont. de Bary in potato - temperature - rainfall allows us to use the proposed multiregression model (F = 7,892, p < 0.001). The multiregression analyze emphasize a strong multiple correlation coefficient of 0.895 which accounts from 81.10% of the predicted attack degree. The regression line, Y =   24.311 + 2.813X1 + 0.122X2 show, in climatic conditions specific for the experimental year 2012,   the bigger influence (more than twice) of the thermic conditions on the Phytophthora infestans Mont. de Bary attack degree in potato, compared to rainfall influence on the same pathogen.Obtaining the regression parameters allows us to build a meta-model for predicting the evolution of the Phytophthora infestans Mont. de Bary attack degree in potato, reliable in a high share, 81.10%, respectively, and presenting the advantage that it gives comparable results, which contribute to increase the consistency of assessments patterns.

In order to evaluate the reaction of different genotypes of creole potato (Solanum tuberosum groups Phureja and Andigena) with regard the disease. A Randomized Complete Block design was established with three repetitions, where 30 genotypes were distributed and three plants were evaluated per repetition during two crop cycles in natural exposure to the pathogen. To assess the disease effect on production, the same genotypes were maintained with chemical control in an adjacent batch. Genotypes classified as tolerant are Chaucha Manzana, Cachuda, Criolla Colombia, Malvaseña, Andina and Criolla, during the first cycle with performance values between 23 to 26t.ha-1 and during the second to Calavera Negra, Chaucha Paisa, Ratona, Criolla Galeras, Ratona Roja, Tornilla Roja and Aguacata with performance values between 23 to 28t.ha-1. The graphic severity scale allowed genotypes to be categorized as susceptible and highly susceptible. The results indicate that for the prevalent pathogen race in this study area, there are no resistance sources within the studied collection.

RésuméWe performed a deep Hi and Hα mapping of M31 and M33 in order to get accurate kinematical data of those two galaxies and also to make a comparison between the Hi and Hα kinematics. The Hi data were obtained with the DRAO interferometer and the Hα data with the Fabry-Perot system of the Observatoire du mont Mégantic using an EMCCD as a detector. These data will give us the best possible datasets to derive accurate rotation curves and mass models for those two Local Group spirals and provide some new data for the Hii regions studies of these galaxies. While the Hi observations are of low resolution (~1 arcmin), the high resolution of the Hα data (~1 arcsec) should allow us to get much more details in the central regions, allowing at the same time a much better determination of the kinematical parameters. Hence, the inner part of the rotation curve, so inportant to constraint properly the mass models, will be determined more accurately.

Full textAbstract:
Abstract U-Pb and Th-Pb dating of monazite from hydrothermal quartz veins (“Alpine veins”) from the Lauzière massif (North Belledonne) together with Ar/Ar ages of adularias from the same veins constrain the age of the last tectono-metamorphic events that affected the External Crystalline Massifs (ECM). Ages obtained are surprisingly young. The study of the structural context of the veins combined with our chronological data, allow us to propose a tectonic scenario of the northern ECM for the 15-5 Ma period, which was poorly documented so far. The quartz veins are of two types: (i) the oldest are poorly mineralized (chlorite and epidote), flat-lying veins. The quartz fibres (= extension direction) are near vertical and seem to be associated with a subvertical dissolution schistosity superimposed upon an early Alpine deformation underlined by “mini-biotite”. They bear a sub-horizontal stretching lineation; (ii) the youngest veins are very rich in various minerals (anatase, rutile, phénacite, meneghinite, beryl, synchysite, ….). They are almost vertical. Their “en echelon” geometry as well as the horizontal attitude of their quartz fibres show a dextral strike-slip regime. Two groups of Th-Pb ages have been obtained: 11 to 10 Ma and 7 to 5 Ma. They were obtained from the most recent veins (vertical veins) sampled in different areas of the massif. The ca. 10 Ma ages are related to veins in the Lauzière granite and its metamorphic country-rocks at about 2 km from the eastern contact of the massif, while the ages of ca. 5 Ma correspond to veins occurring in mylonites along this contact. Adularias provided Ar/Ar ages at ca. 7 Ma. By contrast, a monazite from a vein of the Pelvoux massif (Plan du Lac) yielded a Th-Pb age of 17.6 Ma but in a different structural setting. Except fission track ages, there are very little ages of this range published in the recent literature on the Alps. The latter concern always gold mineralized veins (NE Mont Blanc and SW Lepontine dome). The last compressive tectonic regime dated between 15 and 12 Ma is coeval with (i) the late “Roselend thrust” event, which is recorded in the Mont Blanc by shear-zones with vertical lineation, (ii) the last movements in the basal mylonites of the Swiss Nappes, (iii) the horizontal Alpine veins from the Mont Blanc and Belledonne massifs (with vertical quartz fibres), which are similar to the early veins of the Lauzière. On the contrary, the vertical veins of the Lauzière, dated between 11 and 5 Ma, correspond to a dextral strike slip regime. This suggests that most of the strike-slip tectonics along the ECM took place during two stages (ca. 10 Ma and ca. 7-5 Ma) and not only at 18 Ma as had been proposed previously. Our ages are consistent with the late Miocene-Pliocene overlap of the Digne thrust to the South and to part of the normal movement along the Simplon fault to the North. Thus, all the external crystalline massifs were tectonically active during the late Miocene. This suggests that tectonic events in the external alpine belt may have contributed to some extent to the geodynamical causes of the Messinian crisis.

Full textAbstract:
The current evidence suggests that pacing may not be affected by performance level or sex in trail-running races as may occur in road running races. However, the previous studies included races of >100 km. Therefore, we aimed to verify the influence of performance level and sex on pacing in the last four (2017, 2018, 2019, and 2021) editions of a shorter (56.3 km) ultra-trail running race (i.e., Orsières–Champex–Chamonix; OCC®) that maintained the same race profile. The mean finishing time for the 5656 participants was 10 h 20 min 33 s ± 2 h 01 min 19 s. Pacing variability (CV%) was higher in high-level participants, thus showing a greater ability to adapt their pace to the race profile than low-level runners. Males also had a higher pacing variability than females although the effect sizes were small. Based on the current findings, we may recommend for non-elite OCC® participants to adapt their pace to the race profile with a slower pace during uphills and a faster pace during downhills. Further studies including participants’ experience are necessary to confirm the effectiveness of this suggestion in trail-running races of variable distances.

Full textAbstract:
Biocontrol agents based on strains of microorganisms that participate in mutualistic relationships with host plants, including those based on strains of endophytic bacteria, can be an alternative to chemical pesticides. There are endophytic B. thuringiensis strains that produce insect-toxic proteins and induce systemic resistance of plants to pathogens. An important issue is the possibility of regulation of the relationship of endophytic bacterial strains with the host-plant and their ability to induce plant defense reactions against pathogens by signaling molecules, including salicylic acid (SA). The aim of this work was to study the effect of SA and the endophytic bacterial strain B. thuringiensis B-5351 on the activity of potato plants reactions associated with signaling and biosynthesis of SA, as well as the activity of a potato trypsin inhibitor upon infection with the late blight pathogen. We used sterile test tube potato plants (Solanum tuberosum L.) of the Early Rose cultivar. 20-days-old potato plants were inoculated with a bacterial suspension of B. thuringiensis B-5351 (1*108 cells / ml) in distilled water, or in 1 μM SA solution by applying 5 μl of bacterial suspension to 4 upper leaves (20 μl / plant). Control plants were treated with distilled water, and some plants were treated with 1 μM SA solution in the same volume. On the 7th day after inoculation with B. thuringiensis B-5351, the plants were infected with oomycete P. infestans spores (5 μl of 1*105 spore/ ml suspension per leaf). To assay the damaged area, leaves were photographed; the images were analyzed using the ImageJ software. 24 h after infection with late blight pathogen spores, plants were fixed to assess the transcriptional activity of PR6, PR1 and PAL genes (See Table 1) (using CFX Connect Real-Time PCR Detection System Bio-Rad (USA)), and after 6, 24 and 48 h - to analyze the activity of plant proteinase inhibitors and the content of hydrogen peroxide. We estimated the number of colonyforming units (CFU) of microorganisms in plant tissues after their surface sterilization on the 7th day after inoculation of plants with B. thuringiensis B-5351 bacteria. The significance of the differences between the samples was accessed using Student’s t-test (p<0.05). Tables and Figures show data as the mean of the replicates and their standard deviations (M±SD). All experiments were conducted in three-five biological and three analytical replicates. In this work, we showed that SA presence increased the content of living cells of B. thuringiensis B-5351 bacteria in the internal tissues of plants (2,3±1,5×106 CFU/g) as compared to individual treatment with the bacterial strain under investigation (7,3±1,6×105 CFU/g) (See Table 2). Using the method of RAPD analysis, we established the identity of bacteria isolated from internal tissues of potato plants and the initial strain of B. thuringiensis B-5351 (See Fig. 1). Apparently, such titer of bacterial population regulated by plant signaling molecules in plant tissues is an important factor in the formation of plant resistance. Thus, we did not observe a decrease in the area of late blight symptoms on the leaves of potato plants treated only with B. thuringiensis B-5351, while under the individual action of SA this parameter decreased by half, and upon combined treatment of plants with SA and bacteria B. thuringiensis B-5351 - almost 4 times as compared to water-treated plants (See Fig. 2). Treatment with bacteria B. thuringiensis B-5351 increased the activity of proteinase inhibitors in potato plants only 6 h after infection with the late blight pathogen; in plants treated with bacteria cells of B. thuringiensis B-5351 together with SA, there was an almost a twofold increase in the activity of proteinase inhibitors after 6 and 24 h after infection with oomycete P. infestans. Under the influence of SA, a 15-20% increase in the content of H2O2 in intact plants was observed in all variants. In infected plants treated with SA, the H2O2 content exceeded the control values by more than 40%. In plants treated with a suspension of bacteria B. thuringiensis B-5351 and SA plants, the presence of the late blight pathogen caused a threefold increase in the H2O2 content 6 h after infection (See Fig. 3). In the variant with combined treatment with SA and bacteria B. thuringiensis B-5351 of noninfected plants, the content of PR6 gene transcripts exceeded the control level by 25%, as in infected plants treated with SA. Treatment of plants with SA together with bacteria B. thuringiensis B-5351 increased the number of PR6 gene transcripts by more than 50% relative to water-treated non-infected plants (See Fig. 4). In this work, we found that the strain of endophytic bacteria under investigation promoted the accumulation of transcripts of genes encoding PR1 and PAL proteins to the same extent as SA, both individually and when used together. In the presence of the late blight pathogen, more than a twofold (relative to this level in water-treated intact plants) increase in the content of PAL gene mRNA in potato plants was observed in cases of both individual and combined application of SA and B. thuringiensis B-5351 cells. Thus, treatment with B. thuringiensis B-5351 bacteria together with SA induces salicylate-dependent defense reactions (PR1, PAL), as well as an increase in the transcriptional activity of the PR6 gene, which, according to the literature, is a jasmonate-dependent gene. Our results showed the effectiveness of the composition based on live bacteria B. thuringiensis B-5351 and SA in protecting potato plants from late blight by inducing systemic defense responses in plants. Taking into account the insecticidal activity of the strain under investigation against Russian wheat aphids and Colorado potato beetle, which we previously described, the possibility of increasing plant resistance to late blight by biocontrol agent combining B. thuringiensis B-5351 with SA can open one of the approaches to the development of multifunctional protection of plants from biotic influences.

Prior to 1995, late blight of potatoes (Solanum tuberosum L.) caused by Phytophthora infestans (Mont.) de Bary had not been reported from Delaware for decades. In that year, the fungus was isolated from potato foliage collected from fields in the Dover area that sustained severe foliage loss due to the disease. To establish pathogenicity, potato and tomato plants grown in the greenhouse were inoculated with the isolates obtained and Koch's postulates were completed. Analyses to determine mating type, genotype at two allozyme loci (2), Gpi and Pep, and sensitivity to metalaxyl were also completed. Measurements were made every 5 days and EC50 values were calculated for radial mycelial growth on metalaxyl-amended agar, for leaflets inoculated with P. infestans floated in metalaxyl solutions, and for inoculated potato tuber disks deposited on filter paper saturated with metalaxyl (1). Isolates were pathogenic to potatoes and tomatoes, were A2 mating type with Gpi 100/111/122 and Pep 100/100 (same as US-8), and displayed resistance to metalaxyl up to 140 mg/l. References: (1) K. L.

AbstractThe new mineral mössbauerite (IMA2012−049), Fe63+O4(OH)8[CO3]·3H2O, is a member of the fougèrite group of the hydrotalcite supergroup. Thus, it has a layered double hydroxide-type structure, in which brucite-like layers [Fe63+O4(OH)8]2+ are intercalated with CO32− anions and water molecules. Mössbauerite is the fully oxidized analogue of fougèrite and trébeurdenite, related to them chemically by the exchange of (Fe3+O2−) with (Fe2+OH−). Mössbauerite, intimately intergrown with trébeurdenite, was discovered in intertidal gleys from Mont Saint-Michel Bay, France, along with quartz, feldspars and clay minerals. Mössbauerite is formed by the oxidation of the other members of the fougèrite group. Like them, it occurs as μm-scale platelets in gleys with restricted access to atmospheric O and decomposes rapidly when exposed to air. Identification and characterization of these minerals has relied on an electrochemical study of synthetic analogues and Mössbauer spectroscopy, which inspired the name of the new mineral.Unlike fougèrite and trébeurdenite, which are blue-green, pure synthetic mössbauerite is orange in colour. Detailed optical and other physical properties could not be determined because of the small platelet size and instability. The hardness is probably 2−3, by analogy with other members of the supergroup and the density, calculated from unit-cell parameters, is 2.950 g/cm3. Synchrotron X-ray data indicate that the natural material is a nanoscale intergrowth of 2T and 3T polytypes; the latter probably has the 3T7 stacking sequence. The corresponding maximum possible space group symmetries are Pm1 and P3m1. Unit-cell parameters for the 3T cell are a = 3.032(7) Å, c = 22.258(4) = 367.420 Å and Z = ½.Mössbauer spectroscopy at 78 K indicates that two distinct Fe3+ environments exist in a 2:1 ratio. These are interpreted to be ordered within each layer, but without the development of a threedimensional superlattice. Mössbauerite undergoes gradual magnetic ordering at 70−80 K to a ferromagnetic state, below which it splits into three sextets S1m, S2m and S3m, as measured at 15 K, and shows the same intensity ratio ½:⅙:⅓ as the three doublets for fougèrite D1f, D2f, D3f in the paramagnetic state at 78 K. This suggests that there is also short-range coupling of interlayer carbonate anions with respect to the octahedral layers and that the 2D long-range order of carbonates in interlayers remains unchanged.

ABSTRACTWe present the glacier-wide summer surface mass balances determined by a detailed hydrological balance (sSMBhydro) and the quantification of the uncertainties of the calculations on the Argentière and Mer de Glace-Leschaux drainage basins, located in the upper Arve watershed (French Alps), over the period 1996–2004. The spatial distribution of precipitation within the study area was adjusted using in situ winter mass-balance measurements. The sSMBhydro performance was assessed via a comparison with the summer surface mass balances based on in situ glaciological observations (sSMBglacio). Our results show that the sSMBhydro has an uncertainty of ± 0.67 m w.e. a−1 at Argentière and ± 0.66 m w.e. a−1 at Mer de Glace-Leschaux. Estimates of the Argentière sSMBhydro values are in good agreement with the sSMBglacio values. These time series show almost the same interannual variability. From the marked difference between the sSMBhydro and sSMBglacio values for the Mer de Glace-Leschaux glacier, we suspect a significant role of groundwater fluxes in the hydrological balance. This study underlines the importance of taking into account the groundwater transfers to represent and predict the hydro-glaciological behaviour of a catchment.

Full textAbstract:
Pristine montmorillonite (Mont) was used as raw materials to prepare hydroxyl-Fe-pillared Mont, hydroxyl-Al-pillared Mont, and hydroxyl-Fe-Al-pillared Mont composites. By varying the OH/Fe and Fe/Al molar ratios during the preparation of the pillared Mont, the adsorption capacity of zearalenone (ZEA) and the kinetics were elucidated. The characterization of X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy reveals the adsorption mechanism of pristine and modified Mont. The results indicated that the ZEA adsorption capacity is Mont (0.05 mg/g) << 1.5OH/Fe-Mont (0.28 mg/g) << OH/Al-Mont (0.51 mg/g) < 0.5Fe/Al-Mont (0.56 mg/g) in the condition of pH = 8 and 37°C, in which both 0.5Fe/Al-Mont and OH/Al-Mont reached maximum adsorption capacity and 1.5OH/Fe-Mont attained 5 times the capacity of Mont. Adsorption isotherm studies revealed that Freundlich adsorption isotherms best represented the experimental data. The kinetic data for ZEA adsorption revealed that the Mont adsorption capacity for ZEA equilibrates in 1 hour and is best described using the pseudo-second-order rate equation. The XRD analysis indicated that the amplification of Fe-dominant pillared Mont interlayer spacing is the main reason for the observed increases in the adsorption capacity of ZEA, while Al-dominant pillared Mont has a relatively stable Keggin structure; therefore, interlayer spacing is not the primary mechanism for changes in the adsorption capacity of both OH/Al-Mont and Al-dominant pillared Mont. An FT-IR analysis demonstrated that cationic exchange was the dominant mechanism that allowed ZEA and hydroxyl-Al ions to enter the Mont interlayers, while this cationic exchange mechanism was not the dominant mechanism used by hydroxyl-Fe entering the Mont layers.

Full textAbstract:
In de zomer van 1912 werd met veel enthousiasme de honderdste geboortedag van Hendrik Conscience gevierd. Het eeuwfeest, dat vooral in Antwerpen veel publiek trok, illustreerde hoezeer ook nog aan de vooravond van de Eerste Wereldoorlog dergelijke herinneringsfeesten werden gekenmerkt door een ouder, romantisch idioom. In een traditionele, negentiendeeeuwse praalstoet en een door Emmanuel De Bom opgezette tentoonstelling werd de geschiedenis tot iets heiligs gemaakt, iets dat blijvende trouw afdwong. Maar tegelijk kreeg het eeuwfeest ook een actuele betekenis en werd Conscience niet alleen een erflater, maar ook een opdrachtgever. Tijdens twee ‘plechtige feestzittingen’ presenteerden René De Clercq en Pol De Mont Conscience als vader, die op gepaste wijze moest worden herdacht. Maar zij benadrukten ook dat het Woord van de schrijver tot Daden moest leiden. Dat maakte van het eeuwfeest van 1912 meer dan een romantisch herinneringsfeest: het ging ook om een politieke manifestatie, met een strijdbaar karakter en eigentijdse eisen (‘onze Vlaamsche Hoogeschool’). Dit sloot niet uit dat ernaar werd gestreefd de herinnering aan Conscience te musealiseren. De blik op de verdere Vlaamse ontvoogding vereiste blijkbaar ook een terugblik. Daarmee werden verleden en heden wederzijds op elkaar betrokken.________The splendour of the past, the right to the present. About Conscience’s centenary celebration. The 100th anniversary of the birth of Hendrik Conscience was celebrated with great enthusiasm in the summer of 1912. The centenary celebration, which drew a lot of public in Antwerp in particular, illustrated to which extent such memorial celebrations were characterised by an older, romantic idiom even on the eve of the First World War. A traditional nineteenth century pageant and an exhibition created by Emmanuel De Bom turned history into something holy, that enforced enduring loyalty. At the same time, however, the centenary celebration also acquired a present-day significance and thus Conscience became not only a testator but also an initiator. During two ‘formal festive sessions’ René De Clercq and Pol De Mont presented Conscience as the father who deserved to be remembered in a fitting manner. However, they also emphasized that the Words of the author needed to be translated into Actions. This meant that the 1912 century celebration was more than a romantic commemoration: it was also a political manifestation that was militant in nature and with contemporary demands. (‘Our Flemish University’). This did not exclude that it was attempted to musealize the memory of Conscience. The prospect of a continued Flemish emancipation apparently also required retrospection. Thus the past and the present were interlinked.
