    Description: Red Pompeian paintings, very famous for their deep intensity, are currently suffering from darkening. The origins of this darkening degradation are not clearly identified yet and remain a major issue for curators. In the specific case of cinnabar (HgS)-based red pigment, a photoinduced conversion into black metacinnabar is usually suspected. This work is focused on the blackening of red cinnabar paintings coated on a sparry calcite mortar. Different samples exhibiting different levels of degradation were selected upon visual observations and analyzed by synchrotron-based microanalytical techniques. Atomic and molecular compositions of the different debased regions revealed two possible degradation mechanisms. On one hand, micro X-ray fluorescence elemental maps show peculiar distributions of chlorine and sulfur. On the other hand, X-ray absorption spectroscopy performed at both Cl and S K-edges confirms the presence of characteristic degradation products: (i) Hg- Cl compounds (e.g., corderoite, calomel, and terlinguaite), which may result from the reaction with exogenous NaCl, in gray areas; (ii) gypsum, produced by the calcite sulfation, in black coatings. Metacinnabar is never detected. Finally, a cross section was analyzed to map the in-depth alteration gradient. Reduced and oxidized sulfur distributions reveal that the sulfated black coating consists of a 5-ím-thick layer covering intact cinnabar.

    Description: Tephra fallout constitutes a serious threat to communities around active volcanoes. Reliable short-term 13 forecasts represent a valuable aid for scientists and civil authorities to mitigate the effects of fallout on the 14 surrounding areas during an episode of crisis. We present a platform-independent automatic procedure with Q1 15 the aim to daily forecast transport and deposition of volcanic particles. The procedure builds on a series of 16 programs and interfaces that automate the data flow and the execution and subsequent postprocess of fallout 17 models. Firstly, the procedure downloads regional meteorological forecasts for the area and time interval of 18 interest, filters and converts data from its native format, and runs the CALMET diagnostic model to obtain the 19 wind field and other micro-meteorological variables on a finer local-scale 3-D grid defined by the user. 20 Secondly, it assesses the distribution of mass along the eruptive column, commonly by means of the radial 21 averaged buoyant plume equations depending on the prognostic wind field and on the conditions at the vent 22 (granulometry, mass flow rate, etc). All these data serve as input for the fallout models. The initial version of 23 the procedure includes only two Eulerian models, HAZMAP and FALL3D, the latter available as serial and 24 parallel implementations. However, the procedure is designed to incorporate easily other models in a near 25 future with minor modifications on the model source code. The last step is to postprocess the outcomes of 26 models to obtain maps written in standard file formats. These maps contain plots of relevant quantities such 27 as predicted ground load, expected deposit thickness and, for the case of or 3-D models, concentration on air 28 or flight safety concentration thresholds

    Description: The time for a first book on Geoethics has come. The faster, greedier pace of society and globalization demands it. The comfortable life of scholars in the ivory tower is coming to a rude awakening. People demand understandable information on geohazards, judges condemn scientist and engineers for lack of communication, indigenous people rise in anger accusing experts of misleading them, attempts to avoid transparency in developments still exist, the helplessness of technology to deal with nuclear waste becomes more evident everyday and nature exposes shortcuts in constructing critical facilities with her own awesome force.....

    Description: The significant amounts of selenium(Se)emitted by volcanoesmay have important impact on human health due to the narrow range between nutrition requirement and toxic effects for living organisms upon Se exposure. Although soils play a key role in determining the level in food and water and thereby human health, little is known about the behaviour of Se in volcanic soils. In this work we evaluated the Se release during rainwater–soil interaction under controlled conditions using soils collected on the flanks of Etna volcano and synthetic rain. Seleniumconcentrations in soil leachate solutions displayed a spatial distribution, which cannot be explained by plume deposition, total Se soil concentrations or the presence of Fe oxides. Instead, Al compounds and to a minor extent SOM were identified as the active phases controlling the selenate mobilization during interaction with sulphate-containing rainwater. This shows the importance of soils as reactive interfaces. Selenium is mobilized when volcanic-derived acid rain interacts with poorly developed soils close to the crater. This geogenic process might influence the chemical composition of groundwater and as a result, human health.

    Description: This chapter outlines a framework of the issues addressed by geoethics. Starting from an etymological analysis of the word “geoethics,” we identify the cultural basis on which to expand the debate on geoethics, while also proposing for consideration by the scientific community some questions that may guide the development of future research and practice in geosciences. We attempt to define some fundamental points that, in our opinion, will strengthen geoethics and help its development. The goal of geoethics is to suggest practical solutions and provide useful techniques, and also to promote cultural renewal in how humans perceive and relate to the planet, through greater attention to the protection of life and the richness of the Earth, in all its forms. As each science does, geoethics should also be able to present an image of the world, pointing out the manner in which it can be understood, investigated, designed, and experienced.

    Description: La boutargue est constituée par les ovaires salés et séchés des mulets à grosse tête (Mugil cephalus) et de la courbine (Argyrosomus regius) représente une ressource importante pour la région de Nouakchott et pour la Mauritanie. Pour déterminer la valeur énergétique dans les boutargues, nous avons effectué des dosages des protéines, des glucides, des lipides et des études analytiques des acides gras et des lipides. Les analyses ont révélé que la boutargue contient, par rapport aux autres éléments d’énergie, très peu de glucide : 3,29% dans la boutargue du mulet et 1,95% dans celle de la courbine. Alors que les teneurs en protéines et lipides sont importantes et sont respectivement de 44,44% et 31,68% dans la boutargue du mulet et de 55,11% et 15,86% dans celle de la courbine. La boutargue est d’une grande valeur nutritionnelle. En effet, la boutargue du mulet contient 493,82 kcal/100g, alors que celle de la courbine contient 384,27 kcal/100g. En outre, chaque gramme de boutargue du mulet contient 28,1mg d’acides gras, tandis que celle de la courbine contient 19,7mg. Les acides gras trouvés dans les boutargues étudiées sont subdivisés en 3 groupes: - Les acides gras saturés : 17,9% dans la boutargue du mulet et 1,8% dans celle de la courbine, - Les acides gras monoinsaturés : 39,4% dans la boutargue du mulet et 40,65% dans celle de la courbine, - Les acides gras polyinsaturés : 28,8% pour la boutargue du mulet et 35,89 % dans celle de la courbine. La quantité lipidique du mulet est supérieure à celle de la courbine, mais la quantité de protéine est inférieure. Le taux d’énergie de la boutargue du mulet est supérieur à celui de la courbine. Néanmoins, cette dernière contient plus d’acides gras mono et poly insaturés que celle du mulet.
    Description: تمثل البطارخ، مبايض سمك البوري (Mugil cephalus) والكوربين (Argyrosomus regius) المملحة و المجففة، ثروة هامة لمنطقة نواكشوط ولموريتانيا. لمعرفة مقدار الطاقة في هذه البطارخ، قمنا بدراسة كمية لمكوناتها الطاقية : الدهنيات والبروتينات و السكريات و كيفية للدهنيات. بينت هذه الدراسة أن البطارخ تحتوي على نسب ضئيلة من السكريات. ففي بطارخ الكوربين لاتتجاوز 1,95 % و3,29 %في بطارخ البوري. في هذه الأخيرة ترتفع نسبتي البروتينات و الدهنيات إلى 44,44 % و31,68 % بينما في بطارخ الكوربين تصل هاتين النسبتين إلى%55,11 و15,86 %. كما تبين أن البطارخ غنية بالطاقة حيث توجد بها 493,80 كيلوكالوري/100غ في بطارخ البوري و 384,27 كيلوكالوري/100غ في بطارح الكوربين وكل غرام من بطارخ البوري تحتوي على 28,1 ملغ أحماض دهنية و19,7 أحماض دهنية ببطارخ الكوربين . تنقسم هذه الأحماض إلى ثلاث مجموعات أساسية مختلفة كما وكيفا وهي: - الأحماض الدهنية المشبعة17,9 : % ببطارخ البوري و1,8 % ببطارخ الكوربين. - الأحماض الدهنية أحادية عدم التشبع : % 39,4 ببطارخ البوري و 40,65 % ببطارخ الكوربين. - الأحماض الدهنية متعددة عدم التشبع : 28,8 % ببطارخ البوري و35,89 % ببطارخ الكوربين. نستنتج أن كمية الدهنيات ببطارخ البوري أكثر من نظيرتها بالكوربين، بينما نرى العكس بالنسبة لكمية البروتينات حيث نرى أنها أكثر ببطارخ الكوربين أما كمية الطاقة فتبدو أعلى ببطارخ البوري من بطارخ الكوربين كما تحتوي هذه الأخيرة على أحسن نوعية للدهنيات.
    Description: The boutargue is consisted of salted and dried ovaries of the mullet (Mugil cephalus) and black umber (Argyrosomus regius) is an important resource for the region of Nouakchott and Mauritania. In order to determine the energetic value of the boutargue, we measured the proteins, the carbohydrates and the lipids contents, in addition to the analytical studies of the fatty acids. These experiments revealed that the boutargue contains very low carbohydrate levels: 3,29% for the mullet and 1,95% for the black umber. The protein and the lipid contents were 44,44% and 31,68% respectively for the mullet while, they were respectively 55,11% and 15,86% for the black umber. This study showed the good nutritional quality of boutargue. In fact, the boutargue of the mullet contains 493,82kcal/100g, where as that of the black umber contains 384,27kcal/100g. Each gram of boutargue of the mullet contains 28,1mg of fatty acids and while that of the black umber contain 19,7mg of fatty acids. The fatty acids found in the studied boutargues were subdivided in three groups: - Saturated fatty acids: 17,9% for the mullet and 1,8% for the black umber, - Unsaturated mono fatty acids: 39,4% for the mullet and 40,65% for the black umber, - Polyunsaturated fatty acids: 28,8% for the mullet and 35,89 % for the black umber, As compared to the black umber's boutargue, the mullet boutargue contains high lipid quantity. Where as, the quantity of protein in the black umber’s boutargue was higher as compared to the mullet's boutargue. The energetic rate of the mullet boutargue is higher than that of the black umber. But the black umber boutargue contains more polyunsaturated and unsaturated mono fatty acids.

    Description: The effects of cooking and sterilisation steps on muscle lipid deterioration of Sardinella aurita and Sardina pilchardus canned in olive oil and tomato sauce respectively were investigated. Lipid contents of Sardinella aurita flesh were significantly affected (p 〈 0.05) by the canning process. However, lipid levels of Sardina pilchardus remained constant during processing. The peroxide value and thiobarbituric index increased slightly after the cooking step but changed significantly (p 〈 0.05) following canning. Both canned sardine and sardinella absorbed coating-oil during sterilisation inducing a higher oleic (C18:1 n-9) and linoleic (C18:2 n-6) acids content. Independently of coating-oil category, the eicosapentaenoic (C20:5 n-3) and docosahexaenoic (C22:6 n-3) acids concentrations ranged from 3.00 to 6.24% and from 5.12% to 40.26% respectively. Although, lipids of Sardinella aurita and Sardina pilchardus were slightly affected by the canning process, and they remain a good source of ω3 and ω6 fatty acids.
    Description: Dans le présent travail, les effets de la cuisson et de la stérilisation sur la qualité et la composition en acide gras des lipides de la sardinelle Sardinella aurita et la sardine Sardina pilchardus au cours de la mise en boite dans l’huile d’olive et la sauce de tomate ont été étudiés. La teneur en lipides dans la chair de la sardinelle Sardinella aurita a augmenté significativement (p 〈0.05) après la mise en boite. Cependant, celle de la sardine Sardina pilchardus a demeuré stable dans les mêmes conditions. D’autre part, l’étude des indicateurs d’altération des lipides nous a montré que la qualité des lipides de la sardine est affectée par la stérilisation mais pas par la cuisson. La composition en acides gras de la sardine et la sardinelle en boite de conserve change significativement après stérilisation. En effet, indépendamment de la nature d’huile conservatrice, les lipides de la matière première s’enrichissent en acide oléique (C18:1 n-9) et linoléique (C18:2 n-6). Les lipides de la sardine et la sardinelle en boite représentent une source en acides gras poly insaturés de la familles des ω3 et ω6.

    Description: The boutargue is the salty and dried ovary of the mullet (Mugil cephalus) from Nouakchott (Mauritania) and Tunis (Tunisia). In order to know the nutritional quality of the boutargue, we have used an analytic analysis and dosages of lipids and their fat acids. For this study, we used two different methods of extraction of the lipids: method of Folch modified by Bligh and Dyer and the method of Soxhlet. These experiences show that the boutargue of mullet is rich in lipids, 30.9% in Nouakchott (Atlantic Ocean) and 27,4% in Tunis (Mediterranean Sea). The boutargue is with good nutritional quality. Indeed, each gram of boutargue contains 28,1 mg of fatty acids in Nouakchott and 19,7 mg in Tunisia. Theses fatty acids are subdivide in 3 essential groups: - Fatty acid saturated 17,9% in Atlantic Ocean and 2,8% in Mediterranean Sea. - Fatty acid monounsaturated 39, 4% in Atlantic Ocean and 41,4% in Mediterranean Sea. - Fatty acids polyunsaturated 28, 8% in Atlantic Ocean and 39 % in Mediterranean Sea. The quantity of lipids in Atlantic Ocean boutargue is superior to Mediterranean Sea boutargue but the quality of lipids in Mediterranean Sea boutargue is superior to Atlantic Ocean boutargue
