In this work we search for minimal sets of chiral fermions, with arbitrary quantum numbers, beyond the Standard Model that are anomaly-free and lead to vector-like particles under SU(3) and U(1)_em after symmetry breaking. We further study which of these anomaly free sets lead to unification of the gauge couplings at energy scales higher that 5.0×10^15 GeV in order to be consistent with proton decay bounds. A similar study is performed in the context of the SU(5) gauge group; for some of the anomaly-free sets found it is possible to obtain unification of the gauge couplings with the extra fermions decoupling at high intermediate scales.

The seagrass Posidonia oceanica is widely recognized as an effective bioindicator of the health status of Mediterranean coastal waters. Chlorophyll fluorescence measurements, in particular through the Pulse Amplitude Modulated (PAM) fluorometry method, are performed to study aquatic plant ecology and vitality and to assess their responses to diverse stressful factors. However, the current understanding of P. oceanica photosynthetic responses to environmental stresses does only allow scientists to use the PAM-method as a complementary tool to other more-robust monitoring techniques. Consequently, a more in-depth knowledge of the natural causes of variability of P. oceanica photosynthetic responses are a prerequisite to any surveys relying on that time and cost-effective method. In the framework of the STARECAPMED project, this work aimed to determine the influence of several environmental (depth, daytime, season) and plant-specific characteristics (leaf age, leaf part analyzed, epiphytic coverage) on the photosynthetic responses (Y, ETR, RLC) of P. oceanica. Water temperature, irradiance and several biochemical parameters of the seagrass (chl.a, chl.b, C, N, P, micronutrients such as Fe, Cu) were measured as well. The field survey was performed in a pristine meadow in the Calvi Bay, Corsica. Environmental and plant-physiological characteristics deeply influenced P. oceanica photosynthetic responses. As an example, ETR decreased with depth, contrary to Y that mostly increased. ETR was lower in the basal part of leaf blade, and the epiphytic coverage of leaf tips slightly increased their ETR compared to leaf tips cleaned of epiphytes. Depth and leaf part-related variations in RLC were also observed. Because of this natural variability, it appears essential to develop a consensual protocol of chlorophyll fluorescence measurements to publish reliable and comparable results between studies. We therefore notably suggest to perform measurements close to midday, when photosynthetic responses are the highest; at 10-15 m depth in order to avoid, among others, low depth light irradiance variability; on the middle part of the 3rd-4th external leaf, well developed, highly photosynthetic, and little epiphyted. Finally, because P. oceanica fluorescence was correlated with N, P and chl.b leaf contents, the PAM-method could afterwards be used as bioindicator technique, according to the protocol proposed.

Lot of soil survey focused on agricultural soils. For practical reasons, those soils have a low stone content. So, most of the soil water content sensors are placed on low stone content soils and the calibration equations are developed for them. Yet some researches take an interest in forest soils that are often much different from the previous ones. The differences lie in their stone content and their slope. Lots of studies have proved the importance of making soil specific calibration of the soil water content sensor. As our lab use regularly the 10HS sensors (Decagon Devices, United States) in forested soil, we decided to evaluate the importance of the stone content in the soil moisture measurement. The soil used for this experimentation comes from Gembloux (50◦33’54.9”N, 4◦42’11.3”E). It is silt that has been sieved at 2 mm to remove the gravel. The stones used to form the samples come from an experimental site located in the Belgian Ardennes (50◦1’52.6”N, 4◦53’22.5”E). They are mainly composed of schist with some quartz and sandstone elements. Initially, only five samples were constructed with three replications each. The size and the proportion of stones were the variables. Stones were classified in two groups, the first contains gravels whose size is less than 1,5 cm and a the second contains gravels whose size is comprised between 2 and 3 cm. The proportions of stone selected for the experiment are 0, 20 and 40%. In order to generate validation data, two more samples were constructed with intermediate proportion of stone content (30%). The samples were built in PVC container which dimensions are slightly bigger than the sensor volume of influence (1.1-1.3l). The soil samples were saturated and then dried on a thermal chamber set at about 32◦C. During at least 14 days, the samples soil water content was determined by the sensor measurement with the Procheck read-out system (Decagon Devices, United State) and by weighting the samples thrice a day. The evolution of the soil sample height was monitored as well. As first result, the stone content is a parameter that seems to influence soil water content. The stone size is no important. Because soil moisture deserves to be measured accurately in every soil and to confirm the first results the experiment is going on with more samples, different stone proportions, other sensor positioning and a natural air drying.

André J. Scheen, Monique Marchand, Jean-Christophe Philips (1) (1) Service de Diabétologie, Nutrition et Maladies métaboliques, CHU Sart Tilman, Université de Liège, Liège, Belgique. Relations entre gain baro-réflexe et autres marqueurs de risque chez le patient diabétique de type 2 Relationships between baroreflex gain and other risk markers in patients with type 2 diabetes Objectifs : Le gain baro-réflexe (GBR) est un marqueur de la neuropathie autonome cardiovasculaire (NAC) qui s’avère plus discriminant que le classique R-R E/I ratio. Le but du travail est d’étudier les relations entre le GBR et d’autres marqueurs de risque comme la pression pulsée (PP) et la diminution du débit de filtration glomérulaire (DFG) chez le patient diabétique de type 2 (DT2). Méthodes : Au total, 64 patients DT2 ont été étudiés par enregistrement continu de la pression artérielle (PA) et de la fréquence cardiaque (FC) lors d’un test postural standardisé (test de «squatting» : 1min debout – 1min accroupi – 1min debout). GBR est calculé par la pente de la relation entre les espaces R-R et PA systolique lors du redressement. PP (PAS-PAD) est analysée pendant tout le test et par son augmentation durant l’accroupissement (delta PP). Le DFG est calculé par la formule MDRD avant et après un suivi moyen de 12±5 années. Résultats : Les patients ont été séparés en deux groupes en fonction de la valeur médiane du GBR : G1 (n=34) : </=1,36 msec/mm Hg (moyenne ± SD : 0,77±0,40) vs G2 (n=30) : >1,36 (3,05±0,35). Les sujets de G1 sont légèrement plus âgés (58±7 vs 54±8 ans; p=0,04), mais ont un sexe ratio, une durée du DT2, un taux d’HbA1c et des valeurs de PA comparables aux valeurs de G2. Les patients de G1 ont une FC de base plus élevée (88±15 vs 82±14 bpm; p=0,0462) et un DFG plus bas (79±19 vs 95±19 ml/min; p=0,0479). Si la PP en position debout est comparable (59±15 vs 54±15 mmHg; p=0,1983), elle devient plus élevée en position accroupie (73±18 vs 65±16 mmHg; p=0,0395) chez G1 que chez G2. Lors du redressement, la chute de PA moyenne est significativement plus importante (-46±12 vs -38±12 mmHg; p=0,0079), avec un retard à la récupération des valeurs de base (29±19 vs 21±19 sec; p=0,0107) et une tachycardisation moindre (17±8 vs 23±9 bpm; p=0,0359) chez G1. Par contre, la diminution du DFG durant le suivi est comparable chez G1 vs G2 (-13±21 vs -13±21 ml/min; p=0,8561). Conclusion : Un GBR abaissé, marqueur de la NAC, est associé à une PP élevée en position accroupie (un marqueur indirect de rigidité artérielle) et une diminution du DFG. Par contre, la seule valeur de GBR ne permet pas de prédire l’ampleur de la dégradation de la fonction rénale lors d’un suivi ultérieur de 12 années [less ▲]

This paper deals with the initial development of a methodology for controlling real-life, multi-body dynamical systems in the presence of uncertainties in our knowledge of their exact physical nature as well as uncertainties in the ‘given’ forces acting on them. We assume that both these uncertainties can be time-varying, yet bounded. The methodology is developed in two steps. In the first step an exact control of the so-called nominal system—our best assessment of the real-life physical system and the forces acting on it—is developed. This control is inspired by results from analytical dynamics and involves no linearizations and/or approximations of the nonlinear, nonautonomous system. It also minimizes a suitable norm of the trajectory errors at each instant of time. In the second step, a continuous controller using a generalized sliding mode approach is developed that guarantees that the real-life system tracks, without any chatter and to within pre-specified error bounds, the control requirements that are imposed on the nominal system. Thus an explicit closed-form control for an uncertain, nonlinear, nonautonomous multi-body system that satisfies trajectory control requirements placed on the nominal system (to within pre-specified error bounds), is obtained. An example of a triple pendulum in which there are uncertainties both in the description of its physical parameters and in the description of the gravity field in which it moves is considered. The example demonstrates the simplicity and efficacy of the approach when there are uncertainties both in the description of a dynamical system and in the given forces to which it is subjected.

Holzkirchen full scale dynamic experiments were conducted in the framework of IEA Annex 58 research program with the aim to obtain and apply a high quality experimental dataset for model validation of full scale buildings. A first experiment was conducted in August 2013. Two identical houses were submitted to a side by side experiment, one with blinds up, one with blinds down. That first experience lasted 42 days including an initialization period, a Randomly Ordered Logarithmic Binary Sequence of heat inputs (ROLBS), and a re-initialization followed by a free-float period. A second experiment was conducted in April 2014 in one of the two houses, with higher levels of heating power in the South oriented zones and imposed indoor temperatures in the North oriented zones. Simulations were performed with EES Engineering Equation Solver using simplified RC dynamic models. The discrepancies observed between simulated results and measured data were first explained through a deeper analysis of thermal bridges, a better assessment of solar heat gains and a better assessment of the air duct heat losses. In the second experiment, the results revealed an underestimation of the building transmission heat losses. A candidate explanation might be the air stratification which would enhance heat losses on the ceiling side. A modelization of the upper and lower room air layers was introduced. The resulting simulated indoor temperature profiles were in accordance with the measurements. A complete breakdown of heat losses and heat gains was computed for both houses, using measured temperatures as input data for the simulation. [less ▲]

This paper presents recent improvements of our new solar concentrator design for space application. The concentrator is based on a combination of a diffraction grating (blazed or lamellar) coupled with a Fresnel lens. Thanks to this diffractive/refractive combination, this optical element splits spatially and spectrally the light and focus approximately respectively visible light and IR light onto electrically independent specific cells. It avoid the use of MJs cells and then also their limitations like current matching and lattice matching conditions, leading theoretically to a more tolerant system. The concept is reminded, with recent optimizations, ideal and more realistic results, and the description of an experimental realization highlighting the feasibility of the concept and the closeness of theoretical and experimental results.

To get around UAS limitations and propose a viable solution for wildlife monitoring, the development of new inventory methods is needed. However, most authors use the classic systematic transect method as data processing and statistics are easier. We thus created an application to process data from every type of flight plan and to help detect and compare observations on large datasets. WiMUAS is a small software compatible with the open-source QGIS© that allows the creation of visual maps compatible with geographical information systems based on telemetry data and payload parameters to estimate the covered area. The application also has a slider for animal detection that allows multiple observers to record and compare their results for accurate counts. We then tested it on data from a trial realized on savannah animal populations in Democratic Republic of Congo using the Falcon UAS. We created a new type of flight plan, a rosette-shaped design that can be covered in three flights,.and repeated it twice. More than 5000 images were collected during the six flights. Image projection gives an area of 12,4 km2 for the first trial and of 12,1 km2 for the second. The mean sampling rate for both test is 6,1 %. Observers spotted buffaloes, hippos, warthogs and various antelopes with different success over an average rate of 8 images reviewed per minute. Resulting densities observed by the three observers are similar for each test (coefficient of variation 6,9 and 8,6 % respectively) but mean densities vary a lot between the two trials (23,8 and 6,5 animals/km2 respectively).

In last decades, farmland biodiversity came under large threat. To counteract farmland biodiversity loss and other environmental impacts of intensive agriculture, European farmers can apply Agri-environmental schemes. One of these is the creation of flower strips, a part of the cropping field where flowers are sown or naturally settled. Flower strips are known to increase biodiversity in the agricultural landscape, notably attracting specific insects groups, such as pollinators and natural enemies that can provide valuable pollination and biocontrol services to the crop. However, the plant species composition and management of the strips can have a large influence on the identity and amount of useful insects present in the strips, suggesting the need to develop tailored flower strips to maximize the services delivered. Functional diversity (FD) is sometimes proposed as a promising approach, focusing on plant functional traits rather than plant species itself. Yet, it is not certain that sowing a set of plant species results in the desired vegetation with the desired functional trait composition. Species from soil seed bank or dispersing from neighboring vegetation can settle in the strip, while sown species might not always be equally adapted to local conditions. To test this, we developed seed mixtures with four different levels of FD, based on flower traits, and sew them as flower strips in a conventional arable field. We monitored the vegetation to calculate the FD of the realized vegetation. While the absolute FD values of the realized vegetation were lower than the expected FD values, the realized vegetation showed the same FD gradient as expected from the sown mixtures, indicating that it is possible to manipulate FD in flower strips.

The common hippopotamus (Hippopotamus amphibius L.) is part of the animal species endangered because of multiple human pressures. Monitoring of species for conservation is then essential, and the development of census protocols has to be chased. UAV technology is considering as one of the new perspectives for wildlife survey. Indeed, this technique has many advantages but its main drawback is the generation of a huge amount of data to handle. This study aims at developing an algorithm for automatic count of hippos, by exploiting thermal infrared aerial images acquired from UAV. This attempt is the first known for automatic detection of this species. Images taken at several flight heights can be used as inputs of the algorithm, ranging from 38 to 155 meters above ground level. A Graphical User Interface has been created in order to facilitate the use of the application. Three categories of animals have been defined following their position in water. The mean error of automatic counts compared with manual delineations is +2.3% and shows that the estimation is unbiased. Those results show great perspectives for the use of the algorithm in populations monitoring after some technical improvements and the elaboration of statistically robust inventories protocols.

In this work the stability of TiN and TiC nanopowders in isopropyl alcohol as well as the fabrication of dense and well adhered thin coatings based on TiN and TiC by electrophoretic deposition (EPD) have been evaluated in terms of zeta potential and mass deposited when hydrazine is added. The surface of TiN and TiC nanoparticles has been modified to improve the dispersion in isopropyl alcohol adding a cationic polymer (polyethylenimine) as dispersant with two different molecular weights. The influence of acidic/basic character of the solvent also has been evaluated in order to reach the most efficient EPD process. It was found that the adsorption of polyethylenimine with higher molecular weight can preserve the homogeneity of TiC coatings. The surface of TiN nanoparticles can be tuned in order to achieve a similar polyethylenimine adsorption which also improves the deposition in basic media. [less ▲]

The present paper proposes an account of my research on human and veterinary medicine in Graeco-Roman and Byzantine Egypt, undertaken since 2008 at the CEDOPAL at the University of Liège. This research focuses on literary papyri, particularly on the Anonymus Londiniensis (Hermopolis?, 2d half of the Ist century A.D.), the longest known Greek medical papyrus, as well as on documentary fragments, far more numerous than their literary counterparts, of which several categories have been studied in my PhD dissertation defended in Liège in March 2015.

Reducing pesticide use is one the major issues of today’s agriculture. Among other possibilities, attracting and conserving pest natural enemies in agricultural landscapes by providing them habitats is promising. Wildflower strips (WFS) sown at field margins are one of these potential habitats. They are known to attract and conserve a large diversity of insects, as they provide them food resources such as pollen and nectar, as well as shelter and overwintering sites. However, the risk of attracting insect pests at field margins may represent an obstacle to their adoption by farmers. Conversely, it would be interesting if such WFS could play the role of pest trap crops. In an experimental field sown with WFS intercropped with oilseed rape (OSR) (Brassica napus L.), its coleopteran pests were trapped in both WFS and OSR using yellow pan traps between April and June 2014. More than 130 000 Meligethes spp., Ceutorhynchus spp. and Psylliodes chrysocephalla (L.) adults were trapped. Meligethes spp., Ceutorhynchus spp. were significantly more abundant in the OSR compared with WFS when adults emerged and populations reached their abundance peak. Before and between these periods, the few adults trapped were significantly more abundant in the WFS compared with the OSR. Concerning P. chrysocephala, too few individuals were caught for analysis. Results showed that OSR was more attractive than WFS when coleopteran pests were abundant. In this study, WFS sown for insect conservation may neither favour insect pest conservation at field margin, nor be considered as trap crops. [less ▲]

Integrated optimization techniques for mechatronic systems aim at designing simultaneously the trajectory, the control system and the mechanical structure in order to minimize a performance index. The key advantage of such an integrated approach is the capability to search in a wide design space, to account for many dynamic couplings in an early design stage and to avoid simplifying assumptions which would induce a suboptimal design. This work considers that technique for robotic manipulators with flexible links. It is known that a exible multibody system is often non-minimum phase, here, no restriction is imposed to avoid it. This allows a free choice of the optimization process to select a lighter weight controlled system. Furthermore, the amplitudes of the non-actuated degrees-of-freedom should be reduced in order to limit bodies deformation. The mechanical model is derived using a nonlinear finite element method, which is a useful approach to represent systems with elastic bodies. An optimal control problem is considered to perform that integrated analysis and its time dicretization relies the direct transcription method. [less ▲]

Relations entre marqueurs de neuropathie autonome, pression pulsée et insuffisance rénale chronique chez le patient diabétique de type 2 Relationships between markers of autonomic neuropathy, pulse pressure and chronic kidney disease in patients with type 2 diabetes Objectifs : Le patient diabétique de type 2 (DT2) est exposé à un risque accru de neuropathie autonome cardiovasculaire (NAC), de rigidité artérielle et d’insuffisance rénale chronique (IRC). Le but du travail est d’étudier les relations entre la NAC, PP et le débit de filtration glomérulaire (DFG) chez le patient DT2. Méthodes : L’étude comprend 79 patients DT2 (53H, 26F; âge initial : 56±8 années; durée connue du DT2 : 11±8 années; IMC : 28,4±4,6 kg/m²) analysés par enregistrement continu de la pression artérielle (PA) et de la fréquence cardiaque lors d’un test postural standardisé (test de «squatting» : 1min debout – 1min accroupi – 1min debout). Le gain baro-réflexe (GBR) est calculé par la pente de la relation entre les espaces R-R et PA systolique lors du redressement. La pression pulsée (PP = PAS-PAD) est analysée pendant tout le test et par son augmentation durant l’accroupissement (delta PP). DFG est estimé par la formule MDRD au début et après un suivi moyen de 12±5 ans. Résultats : Les valeurs initiales sont : HbA1c : 8,8± 1,7%; DFG : 86±25 ml/min ; PP : 62±10 mmHg; BRG : 1,8±1,4 msec/mmHg. DFG est inversement corrélé à l’âge (r=-0,317; p=0,020), sans relation avec HbA1c (r=-0,023; p=0,935). DFG est fortement corrélé avec GBR (r=0,453; p=0,008) et, moins, avec SqTs (un autre indice d’atteinte sympathique) (r=0,213; p=0,020), mais pas avec le classique indice de NAC R-R E/I ratio (r=0,092 ; p=0,262). Il n’y a pas de corrélation significative entre DFG et PA moyenne, PAS, PP ou encore delta PP. La diminution de DFG (-12±23 ml/min) lors du suivi de 12 ans n’a pu être corrélée de façon significative aux valeurs initiales et finales d’HbA1c, aux trois marqueurs initiaux de NAC (GBR, RR E/I ratio et SqTs) ou aux divers paramètres initiaux évaluant la PA, même si la relation est proche de la signification pour delta PP, un marqueur de la rigidité artérielle (r= 0,20 p= 0,060). Conclusion : La forte relation inverse initiale entre DFG et GBR suggère que IRC et NAC sont aggravées de façon conjointe et, possiblement, qu’une des deux complications influence l’autre. L’absence de corrélations avec HbA1c et les paramètres PA ou PP pourraient s’expliquer par les interférences liées au traitement en cours. L’absence de toute corrélation entre la chute ultérieure de DFG et les autres paramètres initiaux peut s’expliquer par l’origine multifactorielle de la progression de l’IRC chez le patient DT2.

L’aménagement transsexuel comme solution à l’adolescence La transsexualité est souvent banalisée par les médias, séduits par l’idée facile à vendre d’une âme sexuée, donc du drame de la possible inadéquation entre le sexe psychique et le sexe corporel. L’observation clinique rigoureuse de son élaboration plaide cependant pour une architecture complexe, résultant d’une dynamique subtile entre le psychisme, l’histoire et l’environnement. En effet, dans l’analyse d’un cas clinique, nous constatons que, face au risque de l’effondrement identitaire d’une structure fragile le Moi tente de se renforcer par l’organisation de mécanismes de défense qui élabore une nouvelle identité étayée sur un physique transité vers l’autre sexe. Si l’on analyse les interactions précoces sous l’angle de la formation de l’identité sexuelle, le noyau « genré » du Moi peut subir une double attaque, par manque d’identification au même et par attaque mortifère du différent. Le Moi se trouve ainsi délié et persécuté par des objets partiels ou peu introjectés. A l’adolescence, moment potentiellement traumatique de la sexuation, le jeune se trouve confronté à l’interrogation sur son identité sexuelle, et lorsque le noyau « genré » s’est précisément trouvé fragilisé, l’angoisse surgit, avec le risque d’une bascule psychotique. Dans ces cas extrêmes, la recherche d’une nouvelle enveloppe, remodelage de la peau, permet de contenir l’éclosion du courant psychotique grâce à la disponibilité permanente de l’incorporation du différent, identification certes coûteuse en ressources mais peut-être, à même d’éviter l’effondrement narcissique complet.

TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) is a 60-cm robotic telescope that has been installed in June 2010 at the ESO La Silla Observatory [1]. Operated from Liège (Belgium) it is devoted to the detection and characterisation of exoplanets and to the study of comets and other small bodies in the Solar System. A set of narrowband cometary filters designed by the NASA for the Hale-Bopp Observing Campaign [2] is permanently mounted on the telescope along with classic Johnson-Cousins filters. We describe here the hardware and the goals of the project. For relatively bright comets (V < 12) we measure several times a week the gaseous production rates (using a Haser model) and the spatial distribution of several species among which OH, NH, CN, C2 and C3 as well as ions like CO+. The dust production rates (Afrho) and color of the dust aredetermined through four dust continuum bands from the UV to the red (UC, BC, GC, RC filters). We will present the dust and gas production rates of the brightest comets observed in 2014: C/2012 K1 (PANSTARRS), C/2014 E2 (Jacques), C/2013 A1 (Siding Springs) and C/2013 V5 (Oukaimeden). Each of these comets have been observed at least once a week for several weeks to several months. Light curves with respect to the heliocentric distance will be presented and discussed.

Comet C/2012 S1 (ISON) was one of the Oort cloud comets and dynamically new. This comet was broken at its perihelion passage on UT 2013 November 28.1 (at Rh ~ 17 solar radius). We observed the comet C/2012 S1 (ISON) on UT 2013 November 15 with the High Dispersion Spectrograph (HDS) mounted on the Subaru Telescope atop Mauna Kea, Hawaii. Its heliocentric and geocentric distances were 0.601 and 0.898 AU, respectively. We selected the slit size of 0”.5 x 9”.0 on the sky to achieve the spectral resolution of R = 72,000 from 550 to 830 nm. The total exposure time of comet C/2012 S1 (ISON) was 1200 seconds. We detected many emission lines caused from radicals (e.g., CN, C2, NH2), ions (H2O+), atoms ([OI] and Na I) and also many unidentified lines in the spectra. We report the (1) the ortho-to-para abundance ratios (OPRs) of water and ammonia estimated from the high-dispersion spectra of H2O+ and NH2, (2) the green-to-red line ratio of forbidden oxygen emissions, (3) the isotopic ratios of C2 (the carbon isotopic ratio from Swan band) and CN (the carbon and nitrogen isotopic ratios from red band), (4) the sodium-to-continuum ratio of comet C/2012 S1 (ISON). </PRE></BODY></HTML> [less ▲]

C/2013 A1 (Siding Spring) is a long period comet discovered by Robert H McNaught at Siding Spring Observatory in Australia on January 3, 2013 at 7.2 au from the Sun. This comet will make a close encounter with Mars on October 19, 2014. At this occasion the comet will be extensively observed both from Earth and from several orbiters around Mars.On September 20, 2013 when the comet was around 5 au from the Sun, we started a monitoring with the TRAPPIST robotic telescope installed at La Silla observatory [1]. A set of narrowband cometary filters designed by the NASA for the Hale-Bopp Observing Campaign [2] is permanently mounted on the telescope along with classic Johnson-Cousins B, V, Rc, and Ic filters.We observed the comet continuously at least once a week from September 20, 2013 to April 6, 2014 with broad band filters. We then recovered the comet on May 20. At this time we could detect the gas and started the observations with narrow band filters until early November, covering the close approach to Mars and the perihelion passage.We present here our first results about comet Siding Springs. From the images in the broad band filters and in the dust continuum filters we derived A(θ)fρ values [3] and studied the evolution of the comet activity with the heliocentric distance from September 20, 2013 to early November 2014. We could also detect gas since May 20, 2014. We thus derived gas production rates using a Haser model [4]. We present the evolution of gas production rates and gas production rates ratios with the heliocentric distance.Finally, we discuss the dust and gas coma morphology. [less ▲]

The aim of this study was to evaluate the physico-chemical stability of Belgian Blue beef packaged under high-oxygen atmosphere as a function of a previous aging technique (wet-aging in vacuum conditions vs. carcass-aging). Two muscles (longissimus dorsi vs. rectus femoris) were studied. After a seven-day wet- or carcass-aging step, muscle cuts from 4 Belgian Blue cows were vacuum packaged and stored at −1 °C for up to 28 days. Each 14 days, part of these samples was repackaged under modified atmosphere (70 % O2:30 % CO2), and stored during 7 days at +4 °C. The following parameters were evaluated: color, metmyoglobin %, metmyoglobin reducing activity, fat content, fatty acid profile, lipid oxidation, antioxidant enzyme activities and alpha-tocopherol content. The sensitivity of modified atmosphere repacked meat cuts to oxidation was influenced by the conditions of the previous aging period (wet > carcass conditions), muscle (rectus femoris > longissimus dorsi) and length of the vacuum storage.
