    Full Text Available In Vu Gia-Thu Bon river basin, Vietnam, drought during the dry season affected negatively on rice production. High and uneven rainfall distribution cause flooding in the basin during wet season and cause severe agricultural drought during dry season.This study aimed to point out a higher water productive and economically efficient rice production method to adapt water scarcity in the region. Based on available secondary data, water productivity is calculated for different water saving rice production methods, according to Pereira, et al, (2012’s irrigation water productivity and total productivity equations. The profit of technological change is calculated by partial budget analysis of rice production in that area and a sensitivity analysis supports to point out which input factor is sensitive to farmer’s benefit. Farmer’s psychological and social beliefs are used to create fuzzy logic based decision making model. Although water productivities (ranging 0.441 kg/m3/ha to 0.504 kg/m3/ha are ranked as the second after System of Rice Intensification, we demonstrated that Alternate Wetting and Drying method is a recommendable method to the farmer after considering economic profitability and technical simplicity. The System of Rice Intensification method also could be a suitable method to adopt because this method is the highest water productive method (Water Productivities are ranging from 0.77 kg/m3/ha to 1.02 kg/m3/ha coupled with highest yield of rice, subject to certain ecosystem services and payment policies should be developed to subsidize the reduced benefit resulting from this method.

    principale de la dégradation des terres agricoles et de la diminution de la productivité agricole – si l’on se place du point de vue de la détérioration de la santé des sols – est notre modèle de travail intensif de sols à faible teneur en carbone qui perturbe et affaiblit de nombreuses fonctions importantes des écosystèmes assurées par les sols. La majorité des sols exploités par une agriculture basée sur le travail intensif et non protégés par des résidus organique de surface se déstructurent et se compactent, et sont ainsi davantage exposés au ruissellement et à l'érosion. En outre, la vie et la biodiversité des sols étant privés d’habitat et de matières organiques, le sol voit sa capacité de récupération biologique altérée.L’agriculture de conservation (AC est un système de culture qui repose sur une perturbation mécanique du sol nulle ou minime, un paillis organique permanent, et une diversification des cultures. C’est une solution efficace pour mettre un terme à la dégradation des terres agricoles, et qui est favorable à la réhabilitation des sols et à l’intensification durable de la production agricole. L’AC est aujourd’hui pratiquée par de nombreux exploitants, gros comme petits, sur quelque 125 millions d’hectares dans le monde, et qui se développe à une cadence d’environ 7 millions d’hectares par an.L'AC présente de nombreux avantages pour les exploitants agricoles : meilleurs revenus, diminution des risques financiers, adaptabilité au changement climatique et atténuation de ses effets, etc. Pour les petits exploitants non mécanisés, l’AC offre au final jusqu’à 50 % d’économies de main d’oeuvre, une réduction des tâches pénibles, une stabilité de la production et une meilleure sécurité alimentaire. Pour les exploitants mécanisés, l’AC permet une diminution de la consommation de carburant ainsi que des coûts de machines et de maintenance, et une réduction des moyens et des co

  20. Politiques agricoles et structures agro-industrielles: une approche à partir des tableaux input-output chiliens

    Directory of Open Access Journals (Sweden)

    1992-01-01

    Full Text Available La volonté de certaines grandes puissances agro-exportatrices mondiales de libéraliser les échanges internationaux agro-alimentaires pour accélérer la croissance économique et optimiser l’utilisation des facteurs productifs, s’oppose aux politiques protectionnistes et régulationnistes en vigueur dans bon nombre de pays où l’agriculture doit remplir d’autres fonctions que la seule production de biens consommables ou exportables : autosuffisance ou sécurité alimentaire, équilibre de l’emploi, gestion de l’espace, développement industriel. Développement intégré ou recentrage des modes de produire autour d’un nombre réduit de filières de production, tel est, à notre sens, le véritable enjeu du nouvel ordre international en matière agricole. L’objectif de cette communication est de proposer - à partir de l’analyse des tableaux input-output nationaux et à titre prospectif - une méthode permettant de mettre en regard les échanges extérieurs et la structure interne des systèmes agro-alimentaires. On fait l’hypothèse que l’application indiscriminée de politiques libérales - agro-export led notamment - conduit à l’uniformisation des techniques, la spécialisation des agricultures et des filières de production et débouche à terme sur l’extraversion de l’économie. Un protectionnisme bien orienté conduit, au contraire, à la diversification des productions et des échanges inter-industriels et contribue à l’essor de complexes agro-industriels favorables à la diffusion du progrès technique et l’internationalisation des fruits de la croissance agricole. L’analyse du cas chilien, sur longue période, est particulièrement caractéristique à cet égard.

    2016-02-20

    This work presents the chemical profile of two edible species of mushrooms from the genus Leccinum: Leccinum molle (Bon) Bon and Leccinum vulpinum Watling, both harvested on the outskirts of Bragança (Northeastern Portugal). Both species were prepared and characterized regarding their content in nutrients (i.e., free sugars, fatty acids and vitamins), non-nutrients (i.e., phenolic and other organic acids) and antioxidant activity. To the best of our knowledge, no previous studies on the chemical characterization and bioactivity of these species have been undertaken. Accordingly, this study intends to increase the available information concerning edible mushroom species, as well as to highlight another important factor regarding the conservation of the mycological resources--their potential as sources of nutraceutical/pharmaceutical compounds. Overall, both species revealed similar nutrient profiles, with low fat levels, fructose, mannitol and trehalose as the foremost free sugars, and high percentages of mono- and polyunsaturated fatty acids. They also revealed the presence of bioactive compounds, namely phenolic (e.g., gallic acid, protocatechuic acid and p-hydroxybenzoic acid) and organic acids (e.g., citric and fumaric acids) and presented antioxidant properties.

    Full Text Available Les interactions entre les abeilles et leur milieu sont multiples, complexes, incomprises pour certaines et parfois même controversées. Cette complexité se répercute parfois dans les échanges entre les acteurs liés de près ou de loin à ces insectes pollinisateurs qui évoluent sur un même territoire. Dans ce contexte, l'institut technique et scientifique de l'apiculture et de la pollinisation (ITSAP–Institut de l'abeille, après avoir fait le constat qu'apiculteurs et agriculteurs ne partagent pas toujours la même perception de leur territoire, travaille depuis quelques années à accompagner ces acteurs dans la construction de leviers favorables au maintien durable de ces différentes activités agricoles sur leur territoire. Nous illustrerons cette dynamique à travers différents formats d'actions : l'échange de connaissances dans des ateliers de concertation sous forme de jeu de rôles et l'acquisition et le partage de références dans une expérimentation en plein champs.

    Combien coûte la méthanisation agricole, quelles sont les conditions de la rentabilité ? Pour répondre à ces questions simples en apparence, il faut comprendre comment se construit le « modèle d’entreprise », c’est-à-dire décrire l’organisation de la méthanisation agricole, ses finalités et ses moyens, et la manière dont se créée la valeur ajoutée.

    We have recently reported that activation of the Raf-1/mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) kinase 1/2 (MEK1/2)/ERK1/2 signaling cascade in gastrointestinal carcinoid cell line (BON) alters cellular morphology and neuroendocrine phenotype. The mechanisms by which Raf-1 mediates these changes in carcinoid cells are unclear. Here, we report that activation of the Raf-1 signaling cascade in BON cells induced the expression of focal adhesion kinase (FAK) protein, suppressed the production of neuroendocrine markers, and resulted in significant decreases in cellular adhesion and migration. Importantly, inactivation of MEK1/2 by 1,4-diamino-2,3-dicyano-1,4-bis[2-aminophenylthio]butadiene or abolition of FAK induction in Raf-1-activated BON cells by targeted siRNA led to reversal of the Raf-1-mediated reduction in neuroendocrine markers and cellular adhesion and migration. Phosphorylation site-specific antibodies detected the phosphorylated FAK(Tyr407), but not FAK(Tyr397), in these Raf-1-activated cells, indicating that FAK(Tyr407) may be associated with changes in the neuroendocrine phenotype. Overexpression of constitutively active FAK plasmids (wild-type FAK or FAK(Tyr397) mutant) into BON cells reduced neuroendocrine markers, whereas the FAK(Tyr407) mutant plasmid did not show any decrease in the levels of neuroendocrine markers, indicating that phosphorylation of FAK at the Tyr(407) residue may be important for these effects. Our results showed for the first time that FAK is an essential downstream effector of the Raf-1/MEK1/2/ERK1/2 signaling cascade and negatively regulated the neuroendocrine and metastatic phenotype in BON cells.

    The study area is located in the northeastern part of Tunisia about 60 km south of the Tunis city. It is bounded by the Gulf of Haematite in the East, Djebel Sidi Aberahmane in the West, The town of Nabeul in the south and the area of the town Kelibia in the north. The landscape is a coastal plain slightly sloping (3%) towards the sea. The groundwater of the Oriental coast aquifer system occurs mainly at two levels, a shallow aquifer up to depths of about 50 m whose reservoir is consisted by sediments of the Plio quaternary and a deep aquifer between about 150 and 400 m located in the sand stone formations of Miocene of the anticline of Djebel Sidi Abderrahmene. The climate of the region is semi-arid to sub-humid and of Mediterranean type. There are no perennial rivers in this region; but intense storms occasionally cause surface runoff, which is discharged by the oueds. The study is related to a technical cooperation project with the International Atomic Energy Agency, Vienna, Austria, aimed at the use of isotope techniques to study the seawater intrusion into the coastal aquifers of Cap Bon in Tunisia. In this regard, a better understanding of the recharge and flow regime as well as the origin or salinity of the groundwater was required. To reach this goal, isotope and geochemical investigations were carried out. Water samples were taken from wells, boreholes from deep and shallow aquifer of the Oriental coastal aquifer located between Beni Khiar in the south and Kelibia in the north. The samples were analysed for their chemical and isotopic compositions (18O, 2H, 3H, 13C, 14C, 34S). In the following, the results of these analyses are presented and discussed in terms of the recharge and flow regime of the groundwater and the origin and evolution of its salinity. The results of geochemical and isotopic studies have shown that the groundwater is very eterogeneous and suggest the aquifer is replenished by recent water coming from direct infiltration from rain.

    This study joins within the framework of the S.E.N.S.I.B. project. The principle is to set up a step which allows to compare the sensitivity of two sites in case of radioisotopes releases; as illustration the sites of Marcoule and La Hague are considered. We are interested here in the case of the agricultural productions contaminated by foliar way during an atmospheric chronic release. Every site is characterized by specific vegetable and animal productions. The calculations of activities give an information about the sensitivity of products (mass and surface activities) and on the sensitivity of the Communes ( total activities). The contamination is supposed to be only made about foliar transfer. The studied radioisotopes are the cesium{sup 137}, the cobalt{sup 60}, the strontium{sup 90} and the iodine{sup 131}. For the cesium{sup 137} and the cobalt{sup 60}, the agricultural environment of the site of Marcoule seems globally more sensitive than that of La Hague, in the mean where the total activity in becquerels exported by the agricultural productions produced on the zone of 10 km around the site is more important for Marcoule than for La Hague. For the strontium{sup 90} and for the iodine{sup 131}, both agricultural environments are globally equivalent. This study which privileged the consideration of the regional specificities shows that the key factors of sensitivity are respectively the topographic situation for the deposit, the factor of translocation and the farming output for the vegetable productions and the daily food ration and the factor of transfer for the animal productions.

    Full Text Available The new Farm Bill has just been voted, after difficult negotiations between the White House and Congress. Since the beginning of the commodity-based programs in the 1930s, the agricultural policies in United States were aimed at supporting farm commodity markets and stabilizing farmers incomes. These commodity support policies have been an important contributor to the growth of agricultural productivity and commodity surplus. In the 1950s it became apparent that export demand was capable of creating farm prosperity and became important for the surplus disposal. The US agricultural policies aimed at expanding agricultural exports, and became more offensive as the export competition grew keener. For the first time in 1996, as the market estimates were optimistic, the Fair Act raised the possibility of an end to price support activities as a mean of farm income support. But in 1998 and 1999 weakened export demand led to marked reductions in the prices of the main crops. The 2002 Farm Bill restored the safety net for the farm income. Despite high prices and expansion of demand, and in contradiction with US commitments at the WTO, the new Farm Bill keep on aiming at providing a strong safety net for farm income, which allows the growth of agricultural productivity and the increase in US agriculture competitiveness, and at expanding trade.

    The effective care and well-being of a community is a challenging task especially in an emergency situation. Traditional technology-based silos between health and emergency services are challenged by the changing needs of the community that could benefit from integrated health and safety services. Low-cost smart-home automation solutions, wearable devices and Cloud technology make it feasible for communities to interact with each other, and with health and emergency services in a timely manner. This paper proposes a new community-based care model, supported by technology, that aims at reducing healthcare and emergency services costs while allowing community to become resilient in response to health and emergency situations. We looked at models of care in different industries and identified the type of technology that can support the suggested new model of care. Two prototypes were developed to validate the adequacy of the technology. The result is a new community-based model of care called 'Le Bon Samaritain'. It relies on a network of people called 'Bons Samaritains' willing to help and deal with the basic care and safety aspects of their community. Their role is to make sure that people in their community receive and understand the messages from emergency and health services. The new care model is integrated with existing emergency warning, community and health services. Le Bon Samaritain model is scalable, community-based and can help people feel safer, less isolated and more integrated in their community. It could be the key to reduce healthcare cost, increase resilience and drive the change for a more integrated emergency and care system.

Le plateau Adja est l'une des principales zones de production agricole du sud du Bénin avec plus de 90% de sa population dans l'agriculture. Malheureusement, cette zone de très forte pression fonci��re souffre, contrairement à la théorie de Boserup (3, de la persistance de l'agriculture minière et de la dégradation prononcée de l'environnement cultural. Cette étude a pour objectif d'analyser la dynamique de pauvreté sur tout le plateau Adja, aux fins de caractériser les formes de pauvreté dont la prise en compte s'avère nécessaire pour la promotion de l'agriculture durable dans la zone. A partir d'un échantillon de 122 ménages les données collectées portent essentiellement sur les caractéristiques des ménages, leur exploitation agricole, leur dotation en actifs et leurs états de bien-être en 2000 et en 2007 appréciés par les dépenses de consommation par équivalent-adulte comme indicateur. Les analyses de données ont permis d'identifier les traits qui distinguent les ménages pauvres chroniques des ménages pauvres transitoires sur le plateau Adja. Le niveau d'instruction, le nombre de champs, le capital naturel et le capital physique possédés sont les facteurs discriminants importants des deux catégories de pauvres. Sur la période de 2000 à 2007, la pauvreté transitoire domine la pauvreté chronique avec 36,9% des ménages contre 28,7%. La pauvreté chronique se traduit par un déficit persistant en actifs naturels et physiques. Selon le genre, les ménages dirigés par les femmes souffrent largement plus de la pauvreté chronique (47,1% que les ménages dirigés par les hommes (25,7%. En ce qui concerne les pratiques agricoles, les pauvres chroniques mettent moins en oeuvre les pratiques agricoles de conservation des terres que les pauvres transitoires.

    Full Text Available Les terres agricoles africaines sont convoitées par de nombreux investisseurs étrangers, ce qui se matérialise par une accélération des transactions portant sur des concessions foncières à grande échelle. Ces investissements répondent à des enjeux très divers et font l’objet de contrats rudimentaires, dont les clauses exactes sont souvent méconnues. Ce phénomène très médiatisé est extrêmement controversé et suscite de virulentes critiques, alors que les analyses scientifiques sur le sujet sont encore très rares. Au regard des effets pervers pressentis et pour certains déjà perceptibles, il peut être perçu comme une des dérives d’un nouveau modèle de croissance agricole basé sur la promotion de l’agrobusiness.The African farmlands are the object of the greed of numerous foreign investors which materializes by an acceleration of the transactions carrying on the concession of lands on a large-scale.

    We are proposing to raise woody plants in space for several applications and plant science. Japanese flowering cherry tree is one of a candidate for these studies. Mechanism behind sensing gravity and controlling shape of tree has been studied quite extensively. Even molecular mechanism for the response of plant against gravity has been investigated quite intensively for various species, woody plants are left behind. Morphology of woody branch growth is different from that of stem growth in herbs. Morphology in tree is strongly dominated by the secondary xylem formation. Nobody knows the tree shape grown under the space environment. If whole tree could be brought up to space as research materials, it might provide important scientific knowledge. Furthermore, trees produce excess oxygen, wooden materials for living cabin, and provide biomass for cultivating mushroom and insect as for the space agriculture. Excellent tree shapes which would be deeply related to wood formation improve quality of life under stressful environment in outer space. The serious problem would be their size. Bonsai is one of the Japanese traditional arts. We can study secondly xylem formation, wood formation, under exotic gravitational environment using Bonsai. "CosmoBon" is the small tree Bonsai for our space experiment. It has been recognized that the reaction wood in CosmoBon is formed similar to natural trees. Our goal is to examine feasibility to grow various species of trees in space as bioresource for space agriculture.

    Full Text Available Au Maroc, l’utilisation des eaux souterraines pour l’irrigation a permis un développement agricole rapide dans de nombreuses régions, mais a aussi fait émerger des situations de baisse des niveaux piezométriques des nappes qui menacent la durabilité de cette agriculture irriguée. L’article présente une action de recherche portant sur la conception d’un projet de territoire agricole durable alliant développement agricole et usage pérenne des ressources en eau souterraine. L’étude a eu lieu dans la zone d’Ain Timguenay (province de Séfrou, qui connait un fort développement de la production de pommes et de prunes depuis une quinzaine d’années. Le programme de recherche a impliqué les agriculteurs, la commune rurale d’Ain Timguenay, les institutions du Ministère de l’Agriculture et l’Agence de bassin hydraulique du Sébou. Une analyse des dynamiques agricoles locales et des tendances nationales a servi de support aux discussions. L’étude de l’aquifère et de ses usages a permis d’établir un bilan sommaire et un ordre de grandeur des surfaces qui pourraient encore être plantées sans que les consommations en eau soient supérieures à la recharge de l’aquifère en année pluviométrique moyenne. Une réflexion prospective menée avec les agriculteurs a mis en évidence deux scénarios possibles à l’échelle locale: 1 un scénario où les difficultés économiques que rencontrent actuellement les exploitations de la zone se renforcent, conduisant à un ralentissement des nouvelles plantations, d’où une pression limitée sur la nappe ; 2 un scénario où les exploitations réussissent à faire face aux défis actuels de production et de commercialisation et de ce fait continuent à planter, ce qui conduit à une consommation en eau bien supérieure à la recharge de la nappe. L’ensemble des acteurs impliqués a participé à l’élaboration d’un troisième scénario permettant de concilier d

    About 74% of agricultural soils are affected by water erosion in Tunisia. This intense soil degradation threatens the sustainability of food production in the country. It also leads to the siltation of the numerous hillslide reservoirs that were constructed in the 1990s to protect downstream villages against floods and provide a source of water in cultivated areas. Very dense gully systems are observed in Tunisian agricultural land and in other Mediterranean regions, but their contribution to contemporary sediment supply to hillside reservoirs has not been quantified yet. Still, there is a need to quantify the sediment sources in this region in order to guide the implementation of erosion control measures. Sediment can be supplied by gully systems but it can also be provided by erosion of the superficial layer of cultivated soil. We propose a methodology to estimate the relative contribution of gully erosion vs. interrill erosion to the sediment accumulated in hillside reservoirs. This work was conducted in a pilot catchment (i.e., Kamech catchment, 263ha, Cape Bon, Tunisia) to define guidelines on the number and the location of sediment core samples to collect in the reservoirs, in order to provide relevant information on the evolution of sediment sources throughout the last two decades. Once validated, this methodology will be applied to other catchments of the Tunisian Ridge. We applied the sediment fingerprinting method, which consists in measuring conservative and stable properties in both sources and sinks of sediment to outline their origin. Sampling efforts were concentrated on the field surface (cropland and grassland), gullies and channel banks. Thirteen sediment cores were collected along an upstream-downstream transect across Kamech hillside reservoir, in order to estimate the contribution of each potential sediment source to the material accumulated at the outlet, and to investigate the potential spatial differences of sediment origin across the

    Tourism represents an important source of income and employment in many Mediterranean regions, including the island of Sardinia (Italy) and the Cap Bon peninsula (Tunisia). Climate change may however impact tourism in both regions, for example, by altering the regions' climatic suitability for common tourism types or affecting water availability. This paper assesses the potential impacts of climate change on tourism in the case study regions of Sardinia and Cap Bon. Direct impacts are studied in a quantitative way by applying a range of climate scenario data on the empirically estimated relationship between climatic conditions and tourism demand, using two different approaches. Results indicate a potential for climate-induced tourism revenue gains especially in the shoulder seasons during spring and autumn, but also a threat of climate-induced revenue losses in the summer months due to increased heat stress. Annual direct net impacts are nevertheless suggested to be (slightly) positive in both case study regions. Significant climate-induced reductions in total available water may however somewhat counteract the positive direct impacts of climate change by putting additional water costs on the tourism industry.

    Directory of Open Access Journals (Sweden)

    Meynard Jean-Marc

    2013-07-01

    Full Text Available La diversification des cultures est souvent présentée comme un levier d’action pour accroître la durabilité des systèmes de production agricoles. Bien raisonnée, elle favorise en effet une réduction de l’usage d’intrants extérieurs à l’exploitation – pesticides, engrais, eau – et des nuisances environnementales associées à leur utilisation excessive. À l’inverse, la simplification des systèmes de culture engagée depuis plus de 40 ans s’est accompagnée d’un recours croissant aux intrants. Cependant, malgré son intérêt pour les systèmes de production en termes de durabilité écologique mais aussi économique (répartition des risques, et son inscription dans divers plans et dispositifs incitatifs, la diversification des cultures progresse peu. Les ministères en charge de l’agriculture et de l’environnement ont donc commandé à l’INRA une étude visant à identifier les freins à la diversification des cultures en France et les leviers mobilisables, par les pouvoirs publics notamment, pour la favoriser. L’hypothèse de travail est que ces freins relèvent du fonctionnement global du système agro-industriel, et de la capacité de développement de filières valorisant les cultures de diversification. L’étude a examiné un certain nombre de cas représentatifs de la diversité des filières et notamment de leurs modes d’organisation, qui déterminent la coordination et l’engagement des acteurs économiques impliqués dans le développement d’une culture de diversification.

  3. Seismic sequence stratigraphy of Miocene deposits related to eustatic, tectonic and climatic events, Cap Bon Peninsula, northeastern Tunisia

    The Cap Bon Peninsula, belonging to northeastern Tunisia, is located in the Maghrebian Alpine foreland and in the North of the Pelagian block. By its paleoposition, during the Cenozoic, in the edge of the southern Tethyan margin, this peninsula constitutes a geological entity that fossilized the eustatic, tectonic and climatic interactions. Surface and subsurface study carried out in the Cap Bon onshore area and surrounding offshore of Hammamet interests the Miocene deposits from the Langhian-to-Messinian interval time. Related to the basin and the platform positions, sequence and seismic stratigraphy studies have been conducted to identify seven third-order seismic sequences in subsurface (SM1-SM7), six depositional sequences on the Zinnia-1 petroleum well (SDM1-SDM6), and five depositional sequences on the El Oudiane section of the Jebel Abderrahmane (SDM1-SDM5). Each sequence shows a succession of high-frequency systems tract and parasequences. These sequences are separated by remarkable sequence boundaries and maximum flooding surfaces (SB and MFS) that have been correlated to the eustatic cycles and supercycles of the Global Sea Level Chart of Haq et al. (1987). The sequences have been also correlated with Sequence Chronostratigraphic Chart of Hardenbol et al. (1998), related to European basins, allows us to arise some major differences in number and in size. The major discontinuities, which limit the sequences resulted from the interplay between tectonic and climatic phenomena. It thus appears very judicious to bring back these chronological surfaces to eustatic and/or local tectonic activity and global eustatic and climatic controls.

    Stratigraphy, palynology, petrography, and geochemistry of the Bon Air coal from the Armfield, Dotson, Rutledge, and Shakerag mine sites of Franklin County, Tennessee suggest that Bon Air seams at all sites were small (=1.0 mile, 1.6 km), spatially distinct paleomires that evolved from planar to domed within the fluviodeltaic Lower Pennsylvanian Raccoon Mountain Formation. Of observed palynoflora, 88?97% are from lycopsids prevalent in the Westphalian. Densosporites palynomorphs of small lycopsids (e.g., Omphalophloios) dominate at the shale-hosted Armfield site, while Lycospora palynoflora of large arboreous lycopsids (especially Lepidodendron, with lesser Lepidophloios harcourtii and Lepidophloios hallii) dominate where intercalated siltstone/sandstone/shale hosts the coal (all other sites). Palynoflora of other lycopsids (Sigillaria and Paralycopodites), tree ferns, seed ferns, small ferns, calamites, and cordaites are generally minor. Genera of clastic-associated Paralycopodites are most common in Shakerag's coal (=10%), yet quite rare in Rutledge or Dotson coals. Overall, the palynomorph assemblages suggest that the Bon Air paleomires were forest swamps, and Early Pennsylvanian in age (Westphalian A, Langsettian). Dominant macerals at all sites are vitrinites, with fine collodetrinite (from strongly decomposed plant debris) more common than coarser collotelinite (from well-preserved plant fragments), and with lesser inertinites (fusinite and semifusinite) and liptinites (dominantly sporinite). Shakerag's coal has greatest abundance (mineral-matter-free) of collotelinite (up to 47%) and total vitrinite (74?79%) of any sites, but lowest liptinite (12?14.5%) and inertinite (7?11%). The Dotson and Rutledge seams contain moderate liptinite (21?23%) and highest inertinite (36?37%), lowest vitrinite (=41%), and lowest collotelinite (13?15%). Armfield's seam has relatively high liptinite (26?28%) and vitrinite (56.5?62%), but rather low inertinite (12

    Full Text Available Populations of Leach's Storm-petrel (Oceanodroma leucorhoa; hereafter storm-petrel, one of the most widespread procellariiform seabirds in the world, appear to be declining in many parts of their breeding range. As part of a regional effort to assess status of storm-petrel colonies in eastern North America, we estimated apparent survival and recapture probabilities from 2009 to 2014 for adults on Bon Portage Island (43° 28' N, 65° 44' W, located off the southwestern coast of Nova Scotia, Canada. Mean annual survival estimated for this colony was low (0.78 ± 0.04 compared with other procellariiforms, e.g., > 0.90 for many albatrosses and petrels. Storm-petrels that were fitted with very high frequency (VHF radio tags had an average of 0.11 ± 0.05 (95% confidence interval [CI] = 0.01 to 0.21 higher survival probabilities than those that were not, possibly because VHF tags were attached to known, established breeders. There was weak evidence that survival was reduced by an average of 0.07 ± 0.04 for storm-petrels in study plots that were occupied by Herring Gulls (Larus argentatus and their chicks; however, this result was not statistically significant (95% CI: -0.15 to 0.02. Low adult survival is an early indication that this important colony may be under stress. However, further work is needed to determine if the colony is indeed declining and, if so, to determine the cause(s of the decline so that they may be addressed.

    Full Text Available L’étude présentée dans cet article porte sur le vécu de la première inspection des professeurs stagiaires de l’enseignement agricole. Partant du modèle théorique de la causalité triadique réciproque emprunté à Bandura (1980, 2003, les pratiques du stagiaire lors de l’inspection sont envisagées comme relevant d’interactions mutuelles entre son histoire professionnelle et personnelle, le contexte écologique du stage pédagogique et le déroulement de la séance inspectée. Le dispositif méthodologique repose sur un matériel discursif tiré d’entretiens semi-directifs menés auprès de huit professeurs stagiaires. Les résultats font apparaître trois types de vécus d’inspection : l’inspection vécue comme un moment de formation, comme un jugement technique ou encore comme un châtiment. Le contexte humain et matériel, l’expérience professionnelle du stagiaire ou encore le déroulement de la séance interviennent comme des facteurs de variation de vécus et influencent de façon différenciée l’identité professionnelle des futurs enseignants.The study presented in this article concerns student teachers’ personal experience of their first inspection, in the context of agricultural education. Using the conceptual model of triadic reciprocal causation borrowed from Bandura (1980, 2003, the inspected student teachers' practices are seen as an interactional causal structure made up of the student teachers’ professional and personal history, the environment in which teaching practice is set and the course of the inspected session. The methodology is based on discourse extracts taken from the semi directive interviews of eight student teachers. The results bring to light three kinds of personal experience: inspection taken as a training period, as a test or as a punishment. The material and human context, the student teacher’s professional background and the course of the teaching session appear as variation

    Full Text Available Markets for agricultural commodities are changing patterns: the leadership is moving between commodities as well as between countries. Demands for meals for feed as well as demand for vegetable oil for human consumption have resulted in a strongly growing world market for oilseed which are seriously challenging the leadership to cereals in term of volume (170 million tons vs 200 million tons while already coming first in value ($45 billion vs $25 billion. The growth in demand is mainly localized in emerging countries in Asia (China, India due to rising consumption of white meats: poultry and pork. Countries tend to produce locally the meats and the grains for feed, while accepting to rely strongly on imports for additional needs of proteins for feed and as well as of vegetable oil for human consumption. This is sustaining the growth of oilseed world exchanges. Parallel to new import markets in emerging countries in Asia, new producers are taking the leadership in exports, outpacing the USA and EU, longtime leaders on ag. markets. South America, and Brazil in particular, thanks to land availability and cheap labor are progressively becoming leaders in soybean, pork, poultry, beef, orange juice, sugar… Russia, Ukraine, are resuming a significant presence on grains markets. For the European Union, the new world context leads to a serious review of future positioning, especially in light of the future WTO obligations – less protection on access, elimination of export subsidies and less internal support. EU Animal productions sector will suffer most from the new context. Grains and oilseed EU production will continue to increase. As prices for grains will be curbed to world market level, some additional land may be diverted to oilseed. Nevertheless the availabilities of cereals will maintain high EU export. Biofuels appear to be a strategic outlet for European agricultural sector, biofuels use grains and sugar beet for ethanol as well as oilseed

    Full Text Available L’approche de gestion écosystémique a été adoptée par le Ministère de l’Agriculture et de la Pêche Maritime dans le cadre du Programme d’appui à la politique sectorielle agricole (PAPSA financé par l’Union Européenne. Cette approche a pour objectif l’intégration de la dimension environnementale dans la planification et la programmation des projets de développement agricoles. Les Plans de gestion écosystémique élaborés à cet effet constituent des outils pour la concrétisation d’un développement durable des filières retenues par le programme PAPSA. L’article présente la démarche générale et son application dans le cas de la filière du palmier dattier à Bouanane. L’analyse détaillée de la démarche déployée et des résultats obtenus révèle la nécessité de faire évoluer cette approche pour tendre vers une collaboration accrue, d’une part entre les institutions du Ministère de l’Agriculture et d’autre part entre le Ministère de l’Agriculture, les autres départements ministériels et les bailleurs de fonds.

    Mean contents of trace elements and ash in channel, bench-column, and dump samples of the abandoned Bon Air coal (Lower Pennsylvanian) in Franklin County, Tennessee are similar to Appalachian COALQUAL mean values, but are slightly lower for As, Fe, Hg, Mn, Na, Th, and U, and slightly higher for ash, Be, Cd, Co, Cr, REEs, Sr, and V, at the 95% confidence level. Compared to channel samples, dump sample means are slightly lower in chalcophile elements (As, Cu, Fe, Ni, Pb, S, Sb, and V) and slightly higher in clay or heavy-mineral elements (Al, K, Mn, REEs, Th, Ti, U, and Y), but at the 95% confidence level, only As and Fe are different. Consistent abundances of clay or heavy-mineral elements in low-Br, high-S, high-ash benches that are relatively enriched in quartz and mire-to-levee species like Paralycopodites suggest trace elements are largely fluvial in origin. Factor analysis loadings and correlation coefficients between elements suggest that clays host most Al, Cr, K, Ti, and Th, significant Mn and V, and some Sc, U, Ba, and Ni. Heavy accessory minerals likely house most REEs and Y, lesser Sc, U, and Th, and minor Cr, Ni, and Ti. Pyrite appears to host As, some V and Ni, and perhaps some Cu, but Cu probably exists largely as chalcopyrite. Data suggest that organic debris houses most Be and some Ni and U, and that Pb and Sb occur as Pb-Sb sulfosalt(s) within organic matrix. Most Hg, and some Mn and Y, appear to be hosted by calcite, suggesting potential Hg remobilization from original pyrite, and Hg sorption by calcite, which may be important processes in abandoned coals. Most Co, Zn, Mo, and Cd, significant V and Ni, and some Mn probably occur in non-pyritic sulfides; Ba, Sr, and P are largely in crandallite-group phosphates. Selenium does not show organic or "clausthalite" affinities, but Se occurrence is otherwise unclear. Barium, Mn, Ni, Sc, U, and V, with strongly divided statistical affinities, likely occur subequally in multiple modes. For study area

    A new ternary BOxNy crystal was grown on Si(100) substrate at 500°C by low-frequency (100 kHz) radio-frequency (rf) derived plasma-assisted MOCVD with an organoborate precursor. The as-grown deposits were characterized by SEM, TED, XPS, XRD, AFM and FT-IR. The experimental results showed that BOxNy crystal was apt to be formed at N-rich atmosphere and high temperature. The decrease of hydrogen flux in fed gases was of benefit to form BON crystal structure. The crystal structure of BOxNy was as similar to that of H3BO3 in this study.

    Vu Gia- Thu Bon (VGTB) River Basin, located in the Central Coastal zone of Viet Nam currently faces water shortage. Climate change is expected to exacerbate the challenge. Therefore, there is a need to study the impacts of climate change on water shortage in the river basin. The study adopts a combined top-down and bottom-up climate change impact assessment to address the impacts of climate change on water shortage in the VGTB River Basin. A MIKE BASIN water balance model for the river basin was established to simulate the response of the hydrological system. Simulations were performed through parametrically varying temperature and precipitation to determine the vulnerability space of water shortage. General Circulation Models (GCMs) were then utilized to provide climate projections for the river basin. The output from GCMs was then mapped onto the vulnerability space determined earlier. In total, 9 out of 55 water demand nodes in the simulation are expected to face problematic conditions as future climate changes. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available Climate change is perhaps the most serious environmental threat to the fight against hunger, malnutrition, disease and poverty in Africa, mainly through its impact on agricultural productivity. This paper discusses the challenges of agricultural adaptation to climate change in Nigeria under the categories (adapted from FAO, 2001 - Hunger and Poverty; Agricultural funding for research and technology development; Traditional agricultural practices; Trade Liberalization and Market Development;  Policies, Institutions and Public Goods; and Information and Human Capital. The rural population, who produce more than 70% of the food eaten in Nigeria, are disproportionately poor and face malnutrition and disease. Both government and the private sector, which should drive the sector through consistent policies, robust funding and infrastructure development, have failed to accord this problem the priority it deserves. Moreover, the anticipated benefit from trade liberalization has failed to trickle down to the African farmer, coupled with the inefficient local marketing systems. In addition, the farmers are slow in changing their farming practices such as bush burning, deforestation and rain-fed agriculture and they lack the requisite education, information and training necessary to adapt to climate change. It is recommended that the government should not only decentralize its programs on poverty/HIV-AIDS and agricultural research (funding and activities, but should make them participatory. In addition, there should be an explicit national agricultural policy framework, adequate provision for irrigation, drainage, weather forecasting and other agricultural technology infrastructure, an incentive for training in agriculture, participatory and on-going capacity building for farmers, drought resistant and short duration high yielding crops development, integration of indigenous and modern knowledge on climate change adaptation, strengthening of the extension

    Full Text Available The objective of this research is to investigate positions taken by the narrator of the series “Bons dias!”, Policarpo, created by Machado de Assis, referring to: racial theory, epidemics and science in nineteenth century Brazil. We will take as corpus the chronicles of the series “Bons dias!”, that approach these subjects.The slavery abolition, which occurred on May 13, 1888, among other changes that were taking place in Brazil during the late nineteenth century, such as the discussion regarding the urbanization of Rio de Janeiro city, the fight against epidemics that were devastating the city (yellow fever and malaria, and the debates regarding racial theories allowed the series of chronicles “Bons dias!” to build meanings amongst the readers regarding the latest events.With the analysis of the chosen chronicles it is possible to approach the opinions of Machado de Assis on the events of his time. Machado, “in the voice” ironic of Policarpo, observed and commented on the analyzed themes, being contrary to several opinions of the ruling elite of nineteenth-century Brazil, regarding racial theory, epidemics and science in Brazil. Machado de Assis, through his character, Policarpo, proved to be a critic of various attitudes of the ruling class.

    As many other semi-arid regions, the Cap Bon peninsula (N.E. Tunisia) shows a parallel increase in overexploitation and mineralization of groundwater resources. In the eastern coast and El Haouaria aquifers, the groundwater quality is threatened. Surveys including level measurements, water sampling, chemical analysis (ions Na+, Cl., Ca2+, Mg2+, Br.) and sotopes (18O, 2H, 3H, 13C, 14C) were performed in 2001, 2002 and 2003. Several analysis types were conducted and results are compared with the hydrodynamic information for identifying the main processes involved in the mineralization increase. Particularly, the isotopes were permitting the understanding of the hydrogeological of the concerned aquifers and the localization of the recharge zones. Because the regional situation along the seashore, the seawater intrusion in the unconfined Plio-quaternary aquifer, resulting from the groundwater overexploitation, and obvious explanation for the rising salinity is identified but is not the only cause of the qualitative degradation: the irrigation development that induces the soil leaching and the fertilizers transfer to groundwater over the whole aquifer extent is another major reason of the mineralization increase. Piezometric and salinity maps of the Plio-quaternary aquifer were established. The continuous increase in pumping has created several depressions in the water table, up to 12 m below msl and induced a deterioration of the water quality. The temporal changes in water-table level and salinity are often similar which suggests a strong link between them. Several geochemical approaches were performed to identify the importance of the marine intrusion in the increase in mineralization. The salinity of the groundwater appears to originate from dissolution of minerals in the aquifer system

Agricultural programmes for the conservation of biodiversity in Belgium.Some negative consequences of an intensive agriculture on the environment are in contradiction with the commitments taken, by Belgium among others, at the signature of the Convention on Biodiversity at Rio in 1992. The action plan relative to biodiversity conservation in Belgium tomes as a follow-up of the European Union's policy but also integrates actions initiated at local levels of power such as communes. The Belgian agro-environmental programme (based on EEC regulation 2078/92 includes several parts concerning the Federal Authority, the Regions and the Communities. Federal help measures have been applied for the entire territory with as main objective an extensification of agriculture. These measures are of three types: reconversion to organic farming, a decrease in animal density, and demonstration projects. The Walloon and Flemish Regions have established their own specific agro-environmental programmes which are reviewed here. Through education, the Communities are also concerned by these incentive measures. Nevertheless, in the southern part of Belgium, it is the Walloon Region and not the French Community that will undertake to develop some demonstration projects concerning production practices compatible with environmental protection. Comparable projects will be ran by the Flemish Community, which is also planning to organize specific lectures and training courses on environment. At the municipal level, numerous actions aiming at sustainable agriculture have been initiated: the biodiversity contracta of the "Fondation Roi Baudouin", the operation "1 000 communes pour l'environnement européen" and the "plans communaux de développement de la nature".

  2. Combining hyperspectral imagery and legacy measured soil profiles to map subsurface soil properties in a Mediterranean area (Cap-Bon, Tunisia)

    Lagacherie, Philippe; Sneep, Anne-Ruth; Gomez, Cécile

    2013-04-01

    Previous studies have demonstrated that Visible Near InfraRed (Vis-NIR) Hyperspectral imagery is a cost-efficient way for mapping soil properties at fine resolutions (~5m) over large areas. However, such mapping is only feasible for soil surface since the effective penetration depths of optical sensors do not exceed several millimetres. This study aimed to extend the use of Vis-NIR hyperspectral imagery to the mapping of subsurface properties at three intervals of depth (15-30 cm, 30-60 cm and 60-100 cm) as specified by the GlobalSoilMap project. To avoid additional data collection, our basic idea was to develop an original Digital Soil Mapping approach that combines the digital maps of surface soil properties obtained from Vis-NIR hyperspectral imagery with legacy soil profiles of the region and with easily available images of DEM-derived parameters. The study was conducted in a pedologically-contrasted 300km² cultivated area located in the Cap Bon region (Northern Tunisia). AISA-Dual Vis-NIR hyperspectral airborne data were acquired over the studied area with a fine spatial resolution (5 m) and fine spectral resolution (260 spectral bands from 450 to 2500nm). Vegetated surfaces were masked to conserve only bare soil surface which represented around 50% of the study area. Three soil surface properties (clay and sand contents, Cation Exchange Capacity) were successfully mapped over the bare soils, from these data using Partial Least Square Regression models (R2 > 0.7). We used as additional data a set of images of landscape covariates derived from a 30 meter DEM and a local database of 152 legacy soil profiles from which soil properties values at the required intervals of depths were computed using an equal-area-spline algorithm. Our Digital Soil Mapping approach followed two steps: i) the development of surface-subsurface functions - linear models and random forests - that estimates subsurface property values from surface ones and landscape covariates and that

    Greenhouse heating can be achieved using various systems, for the generator as well as for the exchanger. The exchanger characteristics involve quite different modes of energy distribution, with differing agronomic and economic consequences. This paper focuses on two ground-level heating systems with low temperature (20 40°C) water circulation: a “radiant mulch” exchanger, composed of a network of ground-level heating hoses, and a “buried pipes” exchanger, composed of a network of under-ground pipes. The first part of the paper develops a model for these exchangers and its integration into a previously described greenhouse global model. The second part compares the effects of these exchangers on the greenhouse energetical behaviour with those of classic aerial metallic pipes with hot (50 70°C) water circulation. Le chauffage des serres agricoles peut être réalisé avec divers types de systèmes, tant pour le générateur que pour l'échangeur situé au sein de la serre. Les caractéristiques de l'échangeur induisent des modes de distribution de l'énergie très différents, dont les conséquences agronomiques et économiques peuvent être importantes. Le présent article s'intéresse à deux types d'échangeurs à circulation d'eau “à basse température” (20 40°C) localisés au niveau du sol de la serre: chauffage par gaines en matière plastique posées à même le sol (ou “paillage radiant”), chauffage par réseau de tubes enterrés à faible profondeur dans le sol de la serre. Une première partie développe une modélisation de ces échangeurs et son intégration dans un modèle plus global de la serre agricole, déjà présenté par ailleurs. Une seconde partie exploite cette modélisation en effectuant une analyse comparative de ces échangeurs avec un échangeur de référence constitué de tubes métalliques aériens à circulation d'eau chaude (50 70°C), très classiquement utilisé dans les serres.

    Full Text Available As is the case with many Latin American countries, El Salvador, which is regularly affected by hurricanes and is in transition towards democracy following a period of violent civil war, suffers from major inequality in the distribution of its national wealth, with almost half the population living below the poverty line. It was in light of this that, in 2002, the Secours populaire français intervened in the North-West of the country in the coffee growing area of the southern part of the Ahuachapán department, an area classified as a priority development area by governmental authorities.  This was in the form of a project undertaken in partnership with the NGO FUNDESYRAM (Fundación para el desarrollo socioeconómico y la restauración ambiental - the Foundation for Social-Economic Development and Environmental Rehabilitation, and was co-funded by the European Union and developed over a period of nine years. Its aim was to improve food security and family economics of those in conditions of extreme poverty and it was undertaken using the principles of inter-family solidarity and respect for the environment. The involvement of the partner and the beneficiaries led to a strengthening of communal associations (the ADESCO (Asociación de desarrollo comunal - Community Improvement Associations as well as to the creation of a production association (‘AGROCESA’ Asociación de productores agropecuarios centro sur Ahuachapán – Association of Agriculture and Livestock Production in order to improve the organization, management and support of social and economic development projects. It was this that guaranteed the success of the program and enabled both the capacity building for self-management and the autonomous and unified development of those communities that benefited from the project. This project, that, among other things, contributed to the eradication of infantile malnutrition by ensuring food safety within the family and empowered women

    Full Text Available This study analyzed the profitability level of waterleaf production in three selected agricultural zones of Akwa Ibom State, Nigeria. The study was based on primary data obtained from a random sample of 60 waterleaf farmers and analyzed using descriptive statistics, profitability ratios and regression analysis. The result of the analysis shows that the majority (90% of the farmers had some level of formal education. Labour had the highest percentage (58% of total cost of production, suggesting that waterleaf production was labour intensive in the area.  The average net income per hectare per waterleaf production cycle was N322,413 while the average total cost was N89,307.18. Labour cost constituted the highest percentage of total variable cost. The profitability index (0.78, rate of returns on investment (361%, rate of returns on variable cost (482%, and operating ratio (0.21 suggest that waterleaf production was profitable in the study area. The identified major factors that enhance the output of waterleaf were the application of poultry manure, bigger household size (cheap labour, level of education of the farmer and level of capital. These observations underscore the need for the provision of credit facilities and some kind of adult education programme for the farmers. These will respectively ensure that they apply the right quantity of purchased inputs (like fertilizers, hired labour and capital in their production process and improve their human capital.Cette étude a porté sur l’analyse du taux de rentabilité de la production de grassé dans trois régions agricoles de l’état d’Akwa Ibom, au Nigeria.

    Full Text Available Intensification of farming in the Sahelian-Sudanese region. 2. Productivity and economic risks.his second part concerns the analysis of land productivity and labour results within a traditional farming system and two improved systems experimented on a site in the center-west part of the Senegalese groundnut basin. Intensified farming systems associate farming and livestock and use motorized or draft cultivation (oxen as means of mechanization. Results show that intensification systematically increases crop yields and gives rise to larger amounts of by-products fitting well for use as animal feed. Furthermore, yields stabilize with soil fertility improvement. The economic risk linked to intensification strongly depends on the climatic context. A 400 mm annual rainfall appears as a threshold to insure a net increase of land and labour productivity, justifying an intensification operation that combines plowing, liming material, organic and minerai fertilizer applications. In the climatic risk zone like that where the experimentation took place, the diversification of farming activity increases and stabilizes income. Therefore, productions as cassava or bissap and the integration of a perennial forage crop offer interesting development perspectives. The constraints limiting the adoption of intensified and diversified farming systems are linked to market conditions, time-labour feasibility, soil fertility management and institutional context. To minimize the risks, tactical adjustments are also analyzed.

    Full Text Available How integrate in Peru a non-governmental cooperation project within the framework of an agricultural enterprise ?. After a one year survey among West African Dwarf sheep and goats in four villages and seven flocks of the North-West province of Cameroon, the constraints to increased productivity were studied. Because of agricultural activities leaving little time and few fields to guarantee good feeding and breeding management, mortalities were high, especially in kids and lambs, which limited the production. Reproductive performances, animal viability and body weights were combined to obtain three overal productivity indices for two flocks of goats. The first one was characterized by long intervals between parturitions (14months and lower productivity indices (14, 7kg of one year old kid per dam per year than the second flock where goats were bred with a Toggenburg buck (47, 1 kg of one year old kid per dam per year. However, adult mortalities and thefts were so high in this second flock (62 per cent that productivity fell to 17, 9 kg of one year old kid per dam per year.

    This thesis deals with the radiological consequences of a nuclear accident through the radioactive contamination of the food chain and the subsequent countermeasures for decreasing the fluxes of radionuclides and decontaminating agricultural lands. After a brief summary of the radioprotection ground and context in case of a nuclear accident, this work surveys existing data on the fluxes of radionuclides in soils and from soil to plants. The research work focuses on both the prediction of the fluxes of radionuclides and possible countermeasures: the measurement of the bioavailability of radionuclides in the soil solution, its use in a mathematical expression to quantify the soil-to-plant transfer of caesium and strontium, and the perspectives of an innovative technique of soil decontamination. The obtained results show that based on 4 coefficients, it is possible to predict crop contamination within a 3 % confidence interval: the fluid solid distribution coefficient of radionuclides kd, the amount of chemical analogues of caesium and strontium, i.e. potassium and calcium, respectively, soil pH and a constant characterising the plant species that is concerned. However, it generally appears from soil to plant transfer studies that the reduction of the fluxes of radionuclides is not a promising way of radiological exposure mitigation after a nuclear accident. The work performed shows that it is more efficient to tackle the source of the contamination, i.e. decontaminate the soil. The proposed technique of soil scraping using a turf harvester appears to be the most advantageous among the tested options, for the decontamination of peat-bog meadows. (author).

  16. Productivity

    DEFF Research Database (Denmark)

    Spring, Martin; Johnes, Geraint; Hald, Kim Sundtoft

    Productivity is increasingly critical for developed economies. It has always been important: as Paul Krugman puts it, “Productivity isn’t everything, but in the long run it is almost everything. A country’s ability to improve its standard of living over time depends almost entirely on its ability...... to raise its output per worker”(Krugman, 1994). Analyses of productivity have, by and large, been the preserve of economists. Operations Management (OM) is rooted in a similar concern for the efficient use of scarce resources; Management Accounting (MA) is concerned with the institutionalised measurement...... and management of productivity. Yet the three perspectives are rarely connected. This paper is a sketch of a literature review seeking to identify, contrast and reconcile these three perspectives. In so doing, it aims to strengthen the connections between policy and managerial analyses of productivity....

    Full Text Available Este artigo, fundamentado no conceito do teatro épico e na relação entre literatura e processos de historicidade, tem por objetivo estudar a peça Auto dos bons tratos (2002, da Cia do Latão, grupo representativo de um contexto sócio-histórico específico de retomada do teatro épico no Brasil. A peça tematiza o processo de escravização dos índios, em 1546, pelo primeiro donatário da capitania de Porto Seguro que, marcado pela ética do trabalho capitalista, entra em uma disputa ideológica com a Igreja por ser contrário aos feriados de dia santo. Na prisão, tem uma visão a respeito da cordialidade, que indica a ele o modo ideal de se relacionar com os seus escravos e funcionários. Ao fazer menção a um fato histórico real relatado no processo movido pela Igreja Católica contra o donatário de terras, a peça revisita criticamente um acontecimento representativo da história oficial, em uma perspectiva que pode ser aproximada do materialismo histórico de Walter Benjamin. É, assim, reveladora de um momento histórico específico do processo de implantação do capitalismo em solo brasileiro e de suas consequências. Além disso, este tema é expresso formalmente por meio da apropriação crítica do auto, o que direciona também a um estudo das formas épicas.

    Highlights: • The structure of natural orcelite has been solved for the first time. • The non-stoichiometry for orcelite previously reported was confirmed. • Non-stoichiometry could cause disorder phenomena during the crystal growth. - Abstract: The crystal structure of the mineral orcelite, a rare nickel arsenide reported in the literature with the formula Ni 5−x As 2 (with x = 0.23), was refined using intensity data collected from a crystal from the Bon Accord body, South Africa. This study revealed that the structure is hexagonal, space group P6 3 mc, with a = 6.7922(2), c = 12.4975(5) Å, and V = 499.31(3) Å 3 . The refinement of an anisotropic model led to an R index of 0.028 for 412 independent reflections. The orcelite structure can be described as a distorted variant of the Pd 5 Sb 2 structure. The smaller As atoms are in the centres of distorted tetragonal antiprisms, formed by only Ni atoms. The coordination sphere is completed with two additional Ni atoms opposite to the rectangular faces. Electron microprobe data carried out on the same crystal used for the structural study point to the following formula [on the basis of Σ(As + Fe + Sb)=2]: Ni 4.75 (As 1.93 Fe 0.05 Sb 0.02 ). According to the high-quality structure refinement, the minor elements were found to replace As in the structure. An atomic position for Ni was found to be partially occupied (75%), thus confirming the non-stoichiometry for the mineral orcelite previously reported in literature. Such a deviation from the stoichiometry could represent the driving force favouring disorder phenomena during the growth of the mineral

    Full Text Available Soil science and agricultural development in Rwanda: state of the art. A review. Poor agricultural productivity remains a crucial problem in Rwanda in spite of numerous technological interventions, including aspects of soil management. The objective of this study was to draw lessons from the past with the view to better orient future interventions in soil fertility management. The literature review and iterative field observations were the sources of information. Findings from this study show that substantial progress has been made in the identification of different soil types and their spatial distribution. Factors related to low level of productivity have been identified and sustainable soil fertility management options have been developed at plot level. However, the widespread adoption of these technologies has been problematic. The main reason is the failure to tailor soil fertility management technologies to specific soil types. The study has demonstrated that the soil map of Rwanda (CPR for Carte Pédologique du Rwanda – 1:50,000 – offers a remarkable potential to constitute a tool to solve this problem. In practice however, the CPR remains underutilized, mainly because of its inaccessibility to its potential users (e.g. policy makers, soil fertility experts, agronomists and extensionists. For its effective use, the following is recommended: Rwandan soil scientists need to increase policy makers' awareness about the usefulness of this soil map; agricultural research needs to adapt from the conventional model to a truly participatory and integrated approach; the CPR legend should be elucidated by providing information on the land units in which soils occur and by bridging Soil Taxonomy with the farmers' soil nomenclature; regional soil reference systems should be established that allow linking soil types with the fertility status of arable land and crop yields. This implies the need for training of Rwandan soil scientists in both Soil

Crop management sequence in a risk context.An experimentation carried out in a station during five consecutive years compared the traditional farming system of the Senegalese groundnut basin to two modernized systems, based on a close synergy between agriculture and livestock productions: a system intensified by draught cultivation (oxen and a system using heavy motorization. The experimentation, implemented at a real farm scale, has taken place in pedo-climatic conditions representative of the region. By producing manure and an important work force, livestock strongly contributes to the success of farming activities. Results show that the suggested intensification models have a beneficial effect on the soil fertility. Several technical options are put forward aiming at a reduction of the risks linked to climatic hazards. Among the main adjustments considered in the modernized systems, we can mention: crop diversification, rotation between cereals and short duration crops ("bissap", black-eyed cowpeas, planned minerai fertilizer application and judicious selection of growing season and soil tilling procedures. Results provide interesting technical references for setting up development programs

    It was a grand entourage for the first half of the CMS hadronic forward calorimeter (HF) that was escorted to Cessy, France by the police on 11 July. The impressive trailer carrying the 7-m-long and 4-m-wide element was pushed and pulled by two specially designed trucks. It took the 64-m-long convoy around 5 hours to travel the 15 km to its final destination. The days leading up to this operation involved intensive checks to the balance and pressure of the hydraulic system of the trailer's wheels. As one side of the HF is slightly heavier than the other, it is crucial to take this into account when transporting such a massive object (each half of the HF weighs 260 tonnes). However, once these checks were complete, the transport was safely underway. The second half of the HF also received a police escort on 18 July as it made its way to the assembly hall at Point 5. The HF will be the first major detector to be lowered into the CMS cavern via the gantry crane in the coming months.

  9. Pourquoi les prix agricoles augmentent-ils ?

    Boussard Jean-Marc

    2008-03-01

    Full Text Available Agricultural prices recently rocketed, calling for significant food price increase, and granting farmers large profits they did not claim. Such an increase in agricultural commodity prices were considered perfectly unrealistic a few years ago. Many explanations are now provided, involving drought in Australia, demand for biofuels, and consumer habits evolution in India or in China. Without denying any validity to such assertions, another hypothesis is proposed here, supported by the ID3 model by CIRAD: the recent price upsurge is only the logical consequence of expectation errors and the unstable character of the market equilibrium point. In this context, the deregulation of markets, particularly by the EC (complying with WTO requirements, which, till recently, was the ultimate stockpile operator, created a new situation likely to feed a chaotic cobweb. This implies that the high price episode will only be temporary, and followed by even more depressed prices. Yet, it might happen that the increased volatility leads to an average price higher than during the state involvement, contrary to policy makers expectations.

Atlast we realized that it is still indispensable to work hard in breeding in order to improve rural welfare.

  13. Des habitations à bon marché au Việt Nam. La question du logement social en situation coloniale Public Housing Projects in Việt Nam: the Problem of Habitation in a Colonial Situation

    Full Text Available La crise du logement dans les grandes villes du Việt Nam est récurrente pendant toute la colonisation. Elle touche les Européens, mais surtout les populations locales qui vivent en majorité dans des habitats précaires. A partir des années 1920, face à l’ampleur de la situation, le gouvernement général décide d’adapter dans la colonie les récentes lois françaises en faveur du logement social. Si quelques prototypes d’habitations à bon marché vont être mis en place par la municipalité de Hanoi dans les années 1930, ce n’est que dans les années 1950, pour répondre à la crise sociale que les politiques de logement vont commencer à être significatives. Entre inertie et projets enthousiastes, les politiques de logement révèlent les contradictions du système colonial face à un problème aussi crucial que complexe, mettant en jeu différents acteurs à différents niveaux : le gouvernement général d’Indochine, la résidence supérieure du Tonkin, les municipalités, les associations privées et dans une moindre mesure les sociétés de construction. Du point de vue architectural, les projets mis en place sont des créations hybrides qui montrent une volonté manifeste de s’adapter au style de vie vietnamien.During the colonial period, the main cities of Việt Nam periodically experienced social housing crises. While Europeans did not remain immune from the consequences of a lack of adequate housing, local populations, who constituted the majority in these makeshift constructs, were most deeply affected. Beginning in the 1920s, faced with the urgency of this problem, the general government sought to adapt contemporaneous French laws in favor of social housing to the local colonial situation. Even though some prototypes of affordable housing were constructed by the Hanoi municipality in the 1930s, it was only in the 1950s that government efforts began to have a significant impact. The politics of housing, and

    The Tunisian Medfly rearing facility is located in the north of the country in a small city named Sidi Thabet, near the capital. This facility was designed for rearing the Medfly Genetic Sexing strain (GSS). The facility has been started operations in 2003 in order to release sterile males under 6000 hectares in the north east of the country in the Cap Bon Peninsula. This programme is supported by the Tunisian government, IAEA and FAO. Male only production was not stable for the four first months, due to some constraints. The production is stabilising by the time, after the tune fine off all rearing procedures and adjustment of the environmental control system. Quality control procedures (QC) were put for each procedure of the production from eggs to adult following the procedures established in the International FAO/IAEA/USDA Fruit Flies Quality control Manual

Several aspects are therefore discussed and presented in practical sheets. They concern the health and environment regulation, but not the professional risk prevention (explosion, fire, and so on). These aspects are the project setting up, input materials (animal by-products, organic materials coming from agricultural production or from out of it), waste collection and transport, process steps, organic product valorization, biogas valorization, solid and liquid release management

    2010-10-15

    In France the photovoltaic energy sustained an important growth in 2011, particularly during the first semester. The growth during the second semester is expected to be less important since it will be assured only by the projects that are too advanced to have been impacted by the new legislation. For the government the difference of costs between photovoltaic power and the grid power stays too important to justify big investment. The situation is totally different in Germany, Spain or Italy where the electricity price is far higher. For these countries, photovoltaic power require less financial incentive to become competitive. In France the annual production of photovoltaic power reached 676 GWh in 2010 and is expected to double in 2011 but will stay marginal when compared to the global electricity production of the country (less than 0.2%).

    Full Text Available Agricultural Practices of Burkinabe Migrants in Côte d'Ivoire and Socio-economic Investments Related to the Cultivation of Cocoa. The political-military crisis that Côte d'Ivoire went through from 2000 to 2011 marked the neighboring countries, including Burkina Faso. Indeed, first State providing migrants to Ivory Coast, it faced many difficulties during this period, due to the high concentration of the Burkinabe community that resides there but also due to the commercial exchanges that exist between the two countries. The Ivorian agricultural sector is the domain of choice for many Burkina Faso citizens. We have highlighted in this research the agricultural activities and socio-economic investments related to the cocoa plantations of these migrants. Significant financial exchanges take place annually between the two countries, Burkina Faso being the main beneficiary. The most important financial transfers come from cocoa plantation which is the first export product of the Ivory Coast. It appears that remittances by Burkinabe migrants working in Ivorian plantations are mainly directed towards meeting the food needs of their families and investment in the real estate sector in Burkina Faso. A part of these transfers is absorbed by the impulses of solidarity of planters with their relatives. Thus, the emigrants establish and maintain relations with the family that has remained in the home country.

    Travel in pregnancy is common, particularly as international travel for work and leisure has become more commonplace. Few women are fully aware of the potential risks of travelling while pregnant, particularly the risk of delivering abroad. We describe here the medical risks and the many social, financial, and logistical considerations for travelling during pregnancy. Pertinent considerations include the risks of developing medical complications abroad, immunization considerations, access to obstetrical care in developing countries, travel medical insurance, and airline regulations.

    The US swine industry is large and growing. The quantity of pork desired by consumers of US pork is growing at the rate of 1.5%/y. New production systems and new technology have enabled production per sow to grow at a rate of 4% annually in recent years. Consequently, the number of sows in the United States is declining. Because productivity growth is outpacing demand growth, the deflated price of hogs and pork is declining. Hog production and prices continue to exhibit strong seasonal and cyclic patterns. Pork production is usually lowest in the summer and highest in the fall. Production and prices tend to follow 4-year patterns. The US swine industry continues to evolve toward fewer and larger producers who rely on contracts for both hog production and marketing. In 2000, over half of the hogs marketed were from approximately 156 firms marketing more than 50,000 head annually. These producers finished 60% of their production in contract facilities. Over 90% of their marketings were under contract or were owned by a packer. These producers expressed a high level of satisfaction with hog production. Both they and their contract growers were satisfied with production contracts. These large producers were satisfied with their marketing contracts and planned to continue them in the future. The hog industry has changed a great deal in the last decade. There is little reason to believe this rapid rate of change will not continue. This swine industry is highly competitive and profit driven. Profit margins are too small to allow producers the luxury of ignoring new technology and innovative production systems. Consequently, hog production will continue its rapid evolution from traditional agriculture to typical industry.

    The trial production runs started in the previous report period were continued and have been extended to 67 Ga, 81 Rb/ 81m Kr and 111 In, the production of which will be taken over from the Pretoria cyclotron at the end of this year, when that machine is scheduled to be shut down. After commissioning of the target water cooling system and the helium cooling system for beam foil windows at the beginning of this year, these production runs could also be extended to high beam currents (up to 50 μA). Test consignments of a number of products have been supplied to various potential future users, and 123 I, in the form of Na 123 I capsules as well as 123 I-sodium hippurate, and 52 Fe-citrate have actually been used with success in trial diagnostic studies on patients. A procedure for labelling IPPA and 3-IPMPA with 123 I has been developed, while initial work has also been done on the radioiodination of monoclonal antifibrine antibodies. The last major facility needed for the commencement of the routine radioisotope production programme, namely the multiple-target facility, is now ready for installation in the production vault within the next few weeks, and routine production runs are expected to start in November 1988. 4 figs., 18 refs

  1. Ethanol production

    1985-05-01

    Extractive fermentation is a technique that can be used to reduce the effect of end-product inhibition through the use of a water-immiscible phase which removes fermentation products in situ. This has the beneficial effect of not only removing inhibitory products as they are formed (thus keeping reaction rates high) but also has the potential for reducing product recovery costs. We have chosen to examine the ethanol fermentation as a model system for end product inhibition and extractive fermentation, and have developed a computer model predicting the productivity enhancement possible with this technique. The model predicts an ethanol productivity of 82.6 g/L-h if a glucose feed of 750 g/L is fermented with a solvent having a distribution coefficient of 0.5 at a dilution rate of 5.0 h . This is more than 10 times higher than for a conventional chemostat fermentation of a 250 g/L glucose feed. In light of this, a systematic approach to extractive fermentation has been undertaken involving the screening of more than 1,000 solvents for their extractive properties. UNIFAC and UNIQUAC estimates of distribution coefficients and selectivities were compiled and ranked in a database, together with other important physical properties, such as density, surface tension and viscosity. Preliminary shake-flask and chemostat biocompatibility studies on the most promising solvents have been undertaken. The previous predictive, data base and experimental results are discussed.

    Full Text Available To a modern reader, Robert d’Orbigny’s romance is probably one of the most challenging idylls of the Middle Ages: the young beautiful heroes Floire and Blanchefleur, happily married and ready to found a Christian family (and conceive Berthe, Charlemagne’s mother, become, in two verses at the end of the romance, the proficient perpetrators of genocide (ms. A, v. 3331-3332. Converted through love and empathy, as soon as he is proclaimed Spain’s king, Floire completes a mass conversion through crime and baptism, moved by his tender feelings for Blanchefleur. Jean-Luc Leclanche, editor of the “aristocratic” version of the text, insists on the banality of this form of conversion at that time, and presents the Conte as a pacifist sample of clerical writing. Our paper invites to a new interpretation of this widely circulated story, exploring the emerging ideology of happy ending stories through the concept of “emotional intelligence”.

  6. Landslide mapping and analysis of Korbous area, Cap Bon (Northern Tunisia)

    Djbel Korbous is an important relief dominating the south-eastern edge of the Gulf of Tunis. It is an anticline truncated by a NS fault that passes through the axis of the fold, reason of the collapse of western slopes under the sea. This geometry gives the appearance of a large cased fold and the individualization of series of crests forming the massive of Korbous where altitudes exceed sometimes 400.0 m. Different types of landslides, with various origins and evolution, affect this area. Reactivated pre-existing structures, heterogeneity of lithology and water flow infiltration are the main agents of this phenomenon. The degradation of steep cliffs along the road is strongly accentuated by physico-chemical alteration due to the dissolution of rocks by the runoff flowing through a dense network of fractures and cracks and the spalling of the sandstone bar. The situation has become increasingly critical since 2009 when a large rock slide affected the slope over the sea, threatening, especially the only access to the village with heavy consequences for the population of the region (infrastructure, regional medical center, trade and tourism). The present study aims at defining (i) the main structurally controlled failure types;(ii) the detection of potential instabilities from steep slopes and cliff areas; (iii) the preliminary estimation of potential run-out areas. Geographical Information System GIS (generation of slope map and azimuth map), digital elevation modeling (DEM) are among the most useful tools used for a reliable analysis in this area. Additionally, field work in this paper includes a program of in situ recognition of inventoried instabilities (field measurements, discontinuities characterization, stereoplots and kinematic tests ) and digital photogrammetry using a Canon EOS 7D camera (construction of 3D models and discontinuity measurements were all achieved using VisualSFM and CloudCompare software). The application of those techniques on the area of Korbous showed different families of discontinuities NW-SE and NE-SW whose kinetic conditions allowed the identification of three main failure mechanisms: (1) wedge sliding (dense, intense and inter-crossed fracturing of two dominant directions oriented N075° and N140°); (2) toppling (located in the middle of the cliff where lithology is more less tender) and (3) circular sliding (affects the clay slopes which are sensitive to water and have apparent stability. It's where the main road MC128 passes and this presents the greatest threat facing these instabilities). The dense cutting, weathering and erosion of the whole study area lead, also, to loosen rock blocks from the slope. Their size is variable but the fall height still important reaching in many zones the sea and destroying the protection measures (retaining wall, gabion, drains, etc.). This continued landslide and its evolution in time and space are really alarming and need a more detailed diagnosis.

    The visual esthetics of windmill parks in the province of Quebec was discussed with particular reference to the landscape and environmental impacts that the Le Nordais wind power project has had on communities such as Cap-Chat, Saint-Ulric and Murdochville. The windmill installations either summoned positive or negative responses on the part of the population. Experts now realize that the biophysical and human characteristics that these windmills have on the scenery should be taken seriously. The diversity of opinions has clearly indicated that social acceptance of these projects depends on how promotors and local communities handle the communication between all affected parties. The administrators of the International Appalachian Trail participated in the project in the L'Anse-a-Valleau and Baie-des-Sables communities in Quebec, and by doing so, set up strict municipal rules for distances to be respected between windmills while taking into account the different problem areas of the territory. It was also emphasized that public safety, noise levels and visual impact must be considered. Guidelines have been established by the government for windmill parks, stipulating that laws must be respected for the overall harmony with public lands. The guide developed by the Ministry of Natural Resources and Wildlife Resources in conjunction with municipal communities took into account the activities of the area. Some conditions that were considered to be crucial included respecting local cultures, assuring dialogue between all people involved, and encouraging professional consultation where needed. These conditions promote positive advancement and lead to successful landscape projects. 3 figs.

    This final report for the Swiss Federal Office of Energy (SFOE) discusses the unnecessary operation of electrical equipment. This preliminary study examined in a top-down manner the electrical grid loads at night in Switzerland and attempts to identify unnecessary loads. The results of a bottom-up analysis of seven buildings in the service sector was made. One large complex was also used to identify the sources of night-time loads. Together, these two approaches allowed a first appreciation and a rough quantification of the load caused by the unnecessary operation of equipment in the Swiss electricity grid. The services sector has an estimated share of some 2.4 TWh/a caused by unnecessary operation. In a follow-up project the reduction of unnecessary loads is to be studied in more detail. This second analysis will also have to include loads caused by unnecessary operation during the daytime. The goal of the project is eventually to reduce any unnecessary electric loads and, as a result, the entire electricity demands of Switzerland

  18. Silencing of copine genes confers common wheat enhanced resistance to powdery mildew.

    Science.gov (United States)

    Zou, Baohong; Ding, Yuan; Liu, He; Hua, Jian

    2018-06-01

    Powdery mildew, caused by the biotrophic fungal pathogen Blumeria graminis f. sp. tritici (Bgt), is a major threat to the production of wheat (Triticum aestivum). It is of great importance to identify new resistance genes for the generation of Bgt-resistant or Bgt-tolerant wheat varieties. Here, we show that the wheat copine genes TaBON1 and TaBON3 negatively regulate wheat disease resistance to Bgt. Two copies of TaBON1 and three copies of TaBON3, located on chromosomes 6AS, 6BL, 1AL, 1BL and 1DL, respectively, were identified from the current common wheat genome sequences. The expression of TaBON1 and TaBON3 is responsive to both pathogen infection and temperature changes. Knocking down of TaBON1 or TaBON3 by virus-induced gene silencing (VIGS) induces the up-regulation of defence responses in wheat. These TaBON1- or TaBON3-silenced plants exhibit enhanced wheat disease resistance to Bgt, accompanied by greater accumulation of hydrogen peroxide and heightened cell death. In addition, high temperature has little effect on the up-regulation of defence response genes conferred by the silencing of TaBON1 or TaBON3. Our study shows a conserved function of plant copine genes in plant immunity and provides new genetic resources for the improvement of resistance to powdery mildew in wheat. © 2017 BSPP AND JOHN WILEY & SONS LTD.

    The balance between uranium supply and demand is examined. Should new resources become necessary, some unconventional sources which could be considered include low-grade extensions to conventional deposits, certain types of intrusive rock, tuffs, and lake and sea-bed sediments. In addition there are large but very low grade deposits in carbonaceous shales, granites, and seawater. The possibility of recovery is discussed. Programmes of research into the feasibility of extraction of uranium from seawater, as a by-product from phosphoric acid production, and from copper leach solutions, are briefly discussed. Other possible sources are coal, old mine dumps and tailings, the latter being successfully exploited commercially in South Africa. The greatest constraints on increased development of U from lower grade sources are economics and environmental impact. It is concluded that apart from U as a by-product from phosphate, other sources are unlikely to contribute much to world requirements in the foreseeable future. (U.K.)

    In the context of the LHC experiments, the physics of bottom flavoured hadrons enters in different contexts. It can be used for QCD tests, it affects the possibilities of B decays studies, and it is an important source of background for several processes of interest. The physics of b production at hadron colliders has a rather long story, dating back to its first observation in the UA1 experiment. Subsequently, b production has been studied at the Tevatron. Besides the transverse momentum spectrum of a single b, it has also become possible, in recent time, to study correlations in the production characteristics of the b and the b. At the LHC new opportunities will be offered by the high statistics and the high energy reach. One expects to be able to study the transverse momentum spectrum at higher transverse momenta, and also to exploit the large statistics to perform more accurate studies of correlations

    In the context of the LHC experiments, the physics of bottom flavoured hadrons enters in different contexts. It can be used for QCD tests, it affects the possibilities of B decays studies, and it is an important source of background for several processes of interest. The physics of b production at hadron colliders has a rather long story, dating back to its first observation in the UA1 experiment. Subsequently, b production has been studied at the Tevatron. Besides the transverse momentum spectrum of a single b, it has also become possible, in recent time, to study correlations in the production characteristics of the b and the b. At the LHC new opportunities will be offered by the high statistics and the high energy reach. One expects to be able to study the transverse momentum spectrum at higher transverse momenta, and also to exploit the large statistics to perform more accurate studies of correlations.

    2001-01-01

    Aluminium is the most important non-ferrous metal by quantity. Aluminium is produced by electrolysis of aluminium oxide (also known as alumina). Alumina is produced by refining bauxite. The quantity of primary and secondary aluminium production in ECE-countries between 1992 and 1998 is shown. The European aluminium industry employs approximately 200 000 employees. The annual aluminium production in the European Union was 3.58 million tonnes in 1994, of which 44 % was secondary aluminium. In 1996 3.96 million tonnes of aluminium were produced in the EU, of which 44 % was secondary aluminium. (author)

  4. Uranium production

    Jones, J.Q.

    1981-01-01

    The domestic uranium industry is in a state of stagflation. Costs continue to rise while the market for the product remains stagnant. During the last 12 months, curtailments and closures of mines and mills have eliminated over 5000 jobs in the industry, plus many more in those industries that furnish supplies and services. By January 1982, operations at four mills and the mines that furnish them ore will have been terminated. Other closures may follow, depending on cost trends, duration of current contracts, the degree to which mills have been amortized, the feasibility of placing mines on standby, the grade of the ore, and many other factors. Open-pit mines can be placed on standby without much difficulty, other than the possible cost of restoration before all the ore has been removed. There are a few small, dry, underground mines that could be mothballed; however, the major underground producers are wet sandstone mines that in most cases could not be reopened after a prolonged shutdown; mills can be mothballed for several years. Figure 8 shows the location of all the production centers in operation, as well as those that have operated or are on standby. Table 1 lists the same production centers plus those that have been deferred, showing nominal capacity of conventional mills in tons of ore per calendar day, and the industry production rate for those mills as of October 1, 1981

  5. Novolak Production

    Science.gov (United States)

    Aiba, Hiroshi

    Novolak resins are produced by reacting formaldehyde (30-55% concentration) with phenol under acidic conditions, with oxalic acid as the preferred catalyst and in special conditions, sulfuric acid. Depending on the batch size, all raw material components can be introduced into the reactor, or when there is an increase in the batch size as well as in the reactor volume, the reaction exotherm is controlled by a gradual addition of formaldehyde. Modern novolak production facilities are automated and programmed for reduced operational cost. A flow diagram of a general production line for the manufacture of novolak is shown. Recovery of the novolak is accomplished by the removal of water and devolatilization of crude novolak to molten, low-free phenol novolak resin which can be isolated as flake or pastille or dissolved in appropriate solvents. Novolak is stored either in a solid flake or pastille form or in solution. Most production is conducted under atmospheric conditions, but there are some recent, novel activities such as pressure in a hermetically-closed reactor reaching 0.1-10 MPa by using the heat of reaction without reflux to shorten reaction time, accelerating dehydration time by flash distillation, and providing economic benefit in the cost of novolak production.

    Tequila is obtained from the distillation of fermented juice of agave plant, Agave tequilana, to which up to 49% (w/v) of an adjunct sugar, mainly from cane or corn, could be added. Agave plants require from 8 to 12 years to mature and during all this time cleaning, pest control, and slacken of land are required to produce an initial raw material with the appropriate chemical composition for tequila production. Production process comprises four steps: cooking to hydrolyze inulin into fructose, milling to extract the sugars, fermentation with a strain of Saccharomyces cerevisiae to convert the sugars into ethanol and organoleptic compounds, and, finally, a two-step distillation process. Maturation, if needed, is carried out in white oak barrels to obtain rested or aged tequila in 2 or 12 months, respectively.

    This experiment aims to settle open questions in the hadronic production of electrons, muons and neutrinos. Prominent among these are $e/\\mu$ universality, the contribution of charm decay to lepton pair production, and the "anomalous" low mass pairs.\\\\ The experimental design aims to optimize the combination of:\\\\- electron identification\\\\ - muon identification \\\\ - missing energy measurement for neutrinos \\\\ - vertex identification (for $\\tau \\simeq \\tau_{charm}$). \\\\ \\\\ The major components of the apparatus are shown in the figure. In the vertex region a proton beam of transverse size $\\simeq 50 \\mu$ impinges on a beryllium target of diameter $50 \\mu$, and high precision tracking in the vertex region is achieved by silicon strip detectors. Charged particle momenta are measured using a dipole magnet and high resolution drift chambers. Electrons are identified by the combination of the transition radiation detector and the finely segmented front section of the Uranium/Liquid Argon calorimeter. Essentially t...

    Lewis, Dewi M.

    1995-07-15

    Some 2 0% of patients using radiopharmaceuticals receive injections of materials produced by cyclotrons. There are over 200 cyclotrons worldwide; around 35 are operated by commercial companies solely for the production of radio-pharmaceuticals with another 25 accelerators producing medically useful isotopes. These neutron-deficient isotopes are usually produced by proton bombardment. All commonly used medical isotopes can be generated by 'compact' cyclotrons with energies up to 40 MeV and beam intensities in the range 50 to 400 microamps. Specially designed target systems contain gram-quantities of highly enriched stable isotopes as starting materials. The targets can accommodate the high power densities of the proton beams and are designed for automated remote handling. The complete manufacturing cycle includes large-scale target production, isotope generation by cyclotron beam bombardment, radio-chemical extraction, pharmaceutical dispensing, raw material recovery, and labelling/packaging prior to the rapid delivery of these short-lived products. All these manufacturing steps adhere to the pharmaceutical industry standards of Good Manufacturing Practice (GMP). Unlike research accelerators, commercial cyclotrons are customized 'compact' machines usually supplied by specialist companies such as IBA (Belgium), EBCO (Canada) or Scanditronix (Sweden). The design criteria for these commercial cyclotrons are - small magnet dimensions, power-efficient operation of magnet and radiofrequency systems, high intensity extracted proton beams, well defined beam size and automated computer control. Performance requirements include rapid startup and shutdown, high reliability to support the daily production of short-lived isotopes and low maintenance to minimize the radiation dose to personnel. In 1987 a major step forward in meeting these exacting industrial requirements came when IBA, together with the University of Louvain-La-Neuve in Belgium, developed the Cyclone-30

    Full Text Available Cottage cheese products holds a significant place among the dairy and milk-containing products. The range of products includes cheese: cheese, pastes, creams, cakes, etc. Such diversity can be attributed to their popularity among the population and benefit brought by the body from regular use. Curd protein is much better and easier to digest by the body than protein fish, meat or milk. Rich curd products lysine and methionine. Minerals contained in cheese products have a positive effect on bone formation and structure of tissues. The composition of curd products, in addition to cheese and dairy ingredients may include non-dairy ingredients origin. Today, for the production of cheese products use the most advanced technologies to further enrich its structure and significantly improve the nutritional value. Pine nut is widely used in the manufacture of many dairy products. But, in most cases, the production of dairy products as a filler used pine nut cake, which deprives the finished product valuable cedar oil.

  10. Seismic reflection and structuring characterization of deep aquifer system in the Dakhla syncline (Cap Bon, North-Eastern Tunisia)

    Science.gov (United States)

    Bellali, Abir; Jarraya Horriche, Faten; Gabtni, Hakim; Bédir, Mourad

    2018-04-01

    The Dakhla syncline is located in the North-Eastern Tunisia. It is bounded by Abd El Rahmene anticline to the North-West, El Haouaria Graben to the North-East, Grombalia Graben to the South-West and the Mediterranean Sea to the East. The main aquifer reservoirs of Dakhla syncline are constituted by stacks of fluvial to deltaic Neogene sequences and carbonates. The interpretation of eight seismic reflection profiles, calibrated by wire line logging data of three oil wells, hydraulic wells and geologic field sections highlighted the impact of tectonics on the structuring geometry of aquifers and their distribution in elevated structures and subsurface depressions. Lithostratigraphic correlations and seismic profiles analysis through the syncline show that the principal aquifers are thickest within the central and northern part of the study area and thinnest to the southern part of the syncline. Seismic sections shows that the fracture/fault pattern in this syncline is mainly concentrated along corridors with a major direction of NW-SE and secondary directions of N-S, E-W and NE-SW with different release. This is proved by the complexity structure of Eastern Tunisia, resulted from the interaction between the African and Eurasiatic plates. Isochron maps of aquifers systems exhibited the structuring of this syncline in sub-surface characterized by important lateral and vertical geometric and thickness variations. Seismic sections L1, L2, L3, L4, L5 and petroleum wells showed an heterogeneous multilayer aquifers of Miocene formed by the arrangement of ten sandstone bodies, separated by impermeable clay packages. Oligo-Miocene deposits correspond to the most great potential aquifers, with respectively an average transmissivity estimated: Somaa aquifer 6.5 10-4 m2/s, Sandstone level aquifer 2.6 10-3 m2/s, Beglia aquifer 1.1 10-3 m2/s, Ain Ghrab aquifer 1.3 10-4 m2/s and Oligocene aquifer 2 10-3 m2/s. The interpretation of spatial variations of seismic units and the recognition of tectonic structures and their development may reveal some new insights for hydrogeological aspects.

    2017-12-01

    Full Text Available Apesar de o termo gourmet ser usual no campo da gastronomia, na área beverage and food management são escassos os estudos que investiguem esse fenômeno da culinária no comportamento do consumidor. Assim, o principal objetivo desse estudo é analisar o efeito da assinatura do Chef de cozinha em pratos com abordagens tradicional ou gourmet. Foram realizados dois experimentos com 257 consumidores no total. Os dados foram analisados por meio de técnicas descritivas e análise de variância. Os resultados indicaram que a assinatura do Chef de cozinha aumenta a intenção de compra do prato tradicional, mas não tem efeito sobre a percepção de qualidade. Já para o prato gourmet, ocorre de forma contrária, ou seja, aumenta a percepção de qualidade, mas não tem influencia sobre a intenção de compra do mesmo.

    Purpose: To enable fission products trap with no contamination to coolants and cover gas by the provision of a fission products trap above the upper part of a nuclear power plant. Constitution: Upon fuel failures in a reactor core, nuclear fission products leak into coolants and move along the flow of the coolants to the coolants above the reactor core. The fission products are collected in a trap container and guided along a pipeline into fission products detector. The fission products detector monitors the concentration of the fission products and opens the downstream valve of the detector when a predetermined concentration of the fission products is detected to introduce the fission products into a waste gas processing device and release them through the exhaust pipe.

    Full Text Available In this paper we conceptually discussed the brands’ role in the society, the dimensions of branding and the relationship between the brand and the products. We adhere to the main ideas expressed in the literature, that the brand is more than a product. However the product is needed to render the brand tangible. The product is the magic box that delivers the brand experience. Without the product, the brand meaning would have difficulties in attracting customers. More studies are needed to investigate the brand-product relationship.

    Full Text Available Seafood is very important depending on having high protein rate and easily digestibility by human, for supply to an important part of animal protein needed. Determining the quality of emulsion-type products, emulsion stability, viscosity and gel strength properties are very important. In the production of products specified in this property emulsion; the main protein ratio and properties of raw material used while you; emulsion pH, temperature, ionic violence, mixing speed, type of fat and additives that are used as well. Previous studies show that particularly of products resulting from water emulsified chicken and goat meat emulsified product obtained from a high capacity of emulsified and compared to cattle and sheep meat is close to specifications, preparation of emulsified type products may be appropriate for the use of fish meat. Another quality parameter in the emulsified meat products, viscosity depends on the amount of meat used in direct proportion with the texture. Fish meat animals in connective tissue connective tissue in meat other butchers to rate ratio is quite low. In this respect, the fish meat produced using emulsified products viscosity according to products prepared using other meat products is quite low. Fish meat produced using emulsified fish sausage products based on surimi, sausage and fish pate fish varieties classed emulsion type products.

    2012-01-01

    In Turkey, which ranks the tenth country worldwide in the sunflower (Helianthus annuus L.) production, 55% of the production is carried out in Thrace Region. Therefore, agricultural enterprises in Thrace Region, situated in the European part of Turkey have specialized in producing sunflower, and have become the centre of vegetable oil industry in the region in terms of produced raw material. This research was conducted in 182 agricultural enterprises in 3 provinces of Thrace Region in Turkey and its objective was to determine input/output relations in sunflower production. The study indicates that the determination coefficient (r/sup 2/) derived from Cobb-Douglas production function was significant at 0.01 level and the elasticity coefficients of the variables (except chemical fertilizer) were found beta i positive in derived equation. It was determined that the variable of herbicide cost had the highest value of the marginal effectiveness coefficients and none of the variables was used at economically optimal level in the study area. When the Marginal Technical Substitution and the Price Rates were taken into consideration, it was noted that only the seed cost/hoeing cost was closest to economically optimum level (1.10). According to stepwise analysis the Land Renting Value was determined as the most important variable in sunflower production. (author)

O estudo foi realizado através de uma análise de uma amostra de referência contendo dados de produtividade de 160 juntas soldadas pelo processo Eletrodo Revestido na REDUC (refinaria de Duque de Caxias, utilizando o software ControlTub 5.3. A partir desses dados foram retiradas de forma aleatória, amostras com, respectivamente, 10, 15 e 20 elementos e executadas simulações pelo método de Monte Carlo. Comparando-se os resultados da amostra com 160 elementos e os dados gerados por simulação se observa que bons resultados podem ser obtidos usando o método de Monte Carlo para estimativa da produtividade da soldagem. Por outro lado, na indústria da construção brasileira o valor da média de produtividade é normalmente usado como um indicador de produtividade e é baseado em dados históricos de outros projetos coletados e avaliados somente após a conclusão do projeto, o que é uma limitação. Este artigo apresenta uma ferramenta para avaliação da execução em tempo real, permitindo ajustes nas estimativas e monitoramento de produtividade durante o empreendimento. Da mesma forma, em licitações, orçamentos e estimativas de prazo, a utilização desta técnica permite a adoção de outras estimativas diferentes da produtividade média, que é comumente usada e como alternativa, se sugerem três critérios: produtividade otimista, média e pessimista.The aim of this article is to analyze the feasibility of using Monte Carlo method to estimate productivity in industrial pipes welding of carbon steel based on small samples.

    2016-01-01

    The manufacture and sale of natural products constitute a multi-billion dollar industry. Nearly a third of the American population admit to using some form of complementary or alternative medicine, with many using them in addition to prescription medications. Most patients fail to inform their healthcare providers of their natural product use and physicians rarely inquire. Annually, thousands of natural product-induced adverse events are reported to Poison Control Centers nationwide. Natural product manufacturers are not responsible for proving safety and efficacy, as the FDA does not regulate them. However, concerns exist surrounding the safety of natural products. This review provides details on natural products that have been associated with renal dysfunction. We have focused on products that have been associated with direct renal injury, immune-mediated nephrotoxicity, nephrolithiasis, rhabdomyolysis with acute renal injury, hepatorenal syndrome, and common adulterants or contaminants that are associated with renal dysfunction. The potential for natural products to cause renal dysfunction is justifiable. It is imperative that natural product use be monitored closely in all patients. Healthcare practitioners must play an active role in identifying patients using natural products and provide appropriate patient education. © 2016 S. Karger AG, Basel.

  11. Fermentative production of isobutene.

    Isobutene (2-methylpropene) is one of those chemicals for which bio-based production might replace the petrochemical production in the future. Currently, more than 10 million metric tons of isobutene are produced on a yearly basis. Even though bio-based production might also be achieved through chemocatalytic or thermochemical methods, this review focuses on fermentative routes from sugars. Although biological isobutene formation is known since the 1970s, extensive metabolic engineering is required to achieve economically viable yields and productivities. Two recent metabolic engineering developments may enable anaerobic production close to the theoretical stoichiometry of 1isobutene + 2CO(2) + 2H(2)O per mol of glucose. One relies on the conversion of 3-hydroxyisovalerate to isobutene as a side activity of mevalonate diphosphate decarboxylase and the other on isobutanol dehydration as a side activity of engineered oleate hydratase. The latter resembles the fermentative production of isobutanol followed by isobutanol recovery and chemocatalytic dehydration. The advantage of a completely biological route is that not isobutanol, but instead gaseous isobutene is recovered from the fermenter together with CO(2). The low aqueous solubility of isobutene might also minimize product toxicity to the microorganisms. Although developments are at their infancy, the potential of a large scale fermentative isobutene production process is assessed. The production costs estimate is 0.9 Euro kg(-1), which is reasonably competitive. About 70% of the production costs will be due to the costs of lignocellulose hydrolysate, which seems to be a preferred feedstock.

    Full Text Available Design or product development? The questioning in relation to the employment of such terminology dates back to possible misconceptions regarding interpretation and approach them. Therefore, it can be stated that there are differences between these two terms? In this context, we highlight two views concerning the origin of the design. The first character creative and based on pre-industrial revolution, based on projective and methodologies directed towards the practice of designing products. And second, where design is understood as an industrial process: the development of new products includes, besides a creative procedure are developed, and symbolic formal solutions for products, but also a technical procedure based on the definition of the requirements concerning the product engineering. Is this the most widely accepted interpretation? theoretical studies were conducted from interpretations of the concept of the design proposed by the International Council of Societies of Industrial Design – ICSDI (2012, and for the characterization of the process of product development, we sought to develop an analogy between these two terminologies and can be proved that the use of one of terminology will not cause deviations of interpretation, since both deal with the life cycle of the product. The main results obtained until now the definition of design proposed by the ICSID where it is characterized as a creative activity focused on the complete life cycle of products is the more approaches of the concept of product development.

  14. Industrial production of products like petroleum

    Energy Technology Data Exchange (ETDEWEB)

    Baurier, P J.H.

    1925-02-25

    This invention has as its object a process for separating tars, oils, or gases coming from the distillation of carbonaceous materials, such as lignities or shales, to separate all other substances of the same kind and to prepare products like petroleum. The process for present consideration consists essentially in achieving simultaneously hydrogenation of the material (treated for conversion to stable products) and desulfurization of the materials showing the following characteristics: The substances to be treated are fed in the gaseous state, as vapors or pulverized and made to react at a temperature of 300 to 450/sup 0/C in the presence of excess water vapor, on divided metals capable of decomposing the water with release of hydrogen, at a temperature below 450/sup 0/C.

  17. Volatile products controlling Titan's tholins production

    KAUST Repository

    Carrasco, Nathalie

    2012-05-01

    A quantitative agreement between nitrile relative abundances and Titan\\'s atmospheric composition was recently shown with a reactor simulating the global chemistry occurring in Titan\\'s atmosphere (Gautier et al. [2011]. Icarus, 213, 625-635). Here we present a complementary study on the same reactor using an in situ diagnostic of the gas phase composition. Various initial N 2/CH 4 gas mixtures (methane varying from 1% to 10%) are studied, with a monitoring of the methane consumption and of the stable gas neutrals by in situ mass spectrometry. Atomic hydrogen is also measured by optical emission spectroscopy. A positive correlation is found between atomic hydrogen abundance and the inhibition function for aerosol production. This confirms the suspected role of hydrogen as an inhibitor of heterogeneous organic growth processes, as found in Sciamma-O\\'Brien et al. (Sciamma-O\\'Brien et al. [2010]. Icarus, 209, 704-714). The study of the gas phase organic products is focussed on its evolution with the initial methane amount [CH 4] 0 and its comparison with the aerosol production efficiency. We identify a change in the stationary gas phase composition for intermediate methane amounts: below [CH 4] 0=5%, the gas phase composition is mainly dominated by nitrogen-containing species, whereas hydrocarbons are massively produced for [CH 4] 0>5%. This predominance of N-containing species at lower initial methane amount, compared with the maximum gas-to solid conversion observed in Sciamma-O\\'Brien et al. (2010) for identical methane amounts confirms the central role played by N-containing gas-phase compounds to produce tholins. Moreover, two protonated imines (methanimine CH 2NH and ethanamine CH 3CHNH) are detected in the ion composition in agreement with Titan\\'s INMS measurements, and reinforcing the suspected role of these chemical species on aerosol production. © 2012 Elsevier Inc.

    1995-12-31

    Energy efficient building and office design offers the possibility of significantly increased worker productivity. By improving lighting, heating and cooling, workers can be made more comfortable and productive. An increase of 1 percent in productivity can provide savings to a company that exceed its entire energy bill. Efficient design practices are cost effective just from their energy savings. The resulting productivity gains make them indispensable. This paper documents eight cases in which efficient lighting, heating, and cooling have measurably increased worker productivity, decreased absenteeism, and/or improved the quality of work performed. They also show that efficient lighting can measurably increase work quality by removing errors and manufacturing defects. The case studies presented include retrofit of existing buildings and the design of new facilities, and cover a variety of commercial and industrial settings. Each case study identifies the design changes that were most responsible for increased productivity. As the eight case studies illustrate, energy efficient design may be one of the least expensive ways for a business to improve the productivity of its workers and the quality of its product.

  5. Product Placement in Cartoons

    2014-06-01

    Full Text Available Product placement is a marketing approach for integrating products or services into selected media content. Studies have shown that the impact of advertising on children and youth are large, and that it can affect their preferences and attitudes. The aim of this article is to determine the existing level of product placement in cartoons that are broadcast on Croatian television stations. Content analysis of cartoons in a period of one month gave the following results: in 30% of cartoons product placement was found; most product placement were visual ads, in 89%, however, auditory product placement and plot connection was also found. Most ads were related to toys and it is significant that even 65% of cartoons are accompanied by a large amount of products available on the Croatian market. This is the result of two sales strategies: brand licensing (selling popular cartoon characters to toys, food or clothing companies and cartoon production based on existing line of toys with the sole aim of making their sales more effective.

  18. COMPETITIVE PRODUCT ADVANTAGES

    Directory of Open Access Journals (Sweden)

    Adrian MICU

    2006-01-01

    Full Text Available Cost advantages may be either internal or external. Internal economics of scope, scale, or experience, and external economies of focus or logistical integration, enable a company to produce some products at a lower cost than the competition. The coordination of pricing with suppliers, although not actually economizing resources, can improve the efficiency of pricing by avoiding the incrementalization of a supplier's nonincremental fixed costs and profit. Any of these strategies can generate cost advantages that are, at least in the short run, sustainable. Even cost advantages that are not sustainable, however, can generate temporary savings that are often the key to building more sustainable cost or product advantages later.. Even when a product's physical attributes are not readily differentiable, opportunities to develop product advantages remain. The augmented product that customers buy is more than the particular product or service exchanged. It includes all sorts of ancillary services and intangible relationships that make buying thesame product from one company less difficult, less risky, or more pleasant than buying from a competitor. Superior augmentation of the same basic product can add substantial value in the eyes of consumers, leading them to pay willingly what are often considerable price premiums.

    2017-01-01

    We model a market, such as an online software market, in which an intermediary connects sellers and buyers by displaying sellers' products. With two vertically-differentiated products, an intermediary can place either: (1) one product, not necessarily the better one, on the first page, and the other hidden on the second page; or (2) both products on the first page. We show that it can be optimal for the intermediary to obfuscate a product-possibly the better one-since this weakens price competition and allows the sellers to extract a greater surplus from buyers; however, it is not socially optimal. The choice of which one to obfuscate depends on the distribution of search costs.

    Dark fermentative hydrogen production at thermophilic conditions is attractive process for biofuel production. From thermodynamic point of view, higher temperatures favor biohydrogen production. Highest hydrogen yields are always associated with acetate, or with mixed acetate- butyrate type...... fermentation. On the contrary the hydrogen yield decreases, with increasing concentrations of lactate, ethanol or propionate. Major factors affecting dark fermentative biohydrogen production are organic loading rate (OLR), pH, hydraulic retention time (HRT), dissolved hydrogen and dissolved carbon dioxide...... concentrations, and soluble metabolic profile (SMP). A number of thermophilic and extreme thermophilic cultures (pure and mixed) have been studied for biohydrogen production from different feedstocks - pure substrates and waste/wastewaters.

    Full Text Available Abstract The limited fossil fuel prompts the prospecting of various unconventional energy sources to take over the traditional fossil fuel energy source. In this respect the use of hydrogen gas is an attractive alternate source. Attributed by its numerous advantages including those of environmentally clean, efficiency and renew ability, hydrogen gas is considered to be one of the most desired alternate. Cyanobacteria are highly promising microorganism for hydrogen production. In comparison to the traditional ways of hydrogen production (chemical, photoelectrical, Cyanobacterial hydrogen production is commercially viable. This review highlights the basic biology of cynobacterial hydrogen production, strains involved, large-scale hydrogen production and its future prospects. While integrating the existing knowledge and technology, much future improvement and progress is to be done before hydrogen is accepted as a commercial primary energy source.

  11. Petroleum product market outlook

    International Nuclear Information System (INIS)

    2005-09-01

    The influence of petroleum market disturbances on price increases was discussed with particular reference to Hurricane Katrina and the loss of refinery production and damage to oil infrastructure in the United States. The supply of petroleum products in Canada will be very tight heading into the winter of 2006, despite the fact that Canadian refineries are operating at full capacity to ensure an adequate supply of gasoline and diesel fuel for consumers. In addition to refinery production, petroleum supplies are also determined by the adequacy of inventories and the efficiency of the infrastructure in place to deliver products to where they are needed. The lack of spare capacity has reduced the flexibility of the North American refining system to respond to further disruptions. Refiners were asked to provide information on 4 areas of their operations in order for Natural Resources Canada to analyze the short-term outlook for petroleum products markets. The 4 areas included refinery utilization rates and capability to increase production; any planned refinery turnaround that would affect petroleum product supplies; inventory levels compared to levels in previous years; and, any logistical problems that could affect product distribution. A graph depicting the relationship between Canadian production of gasoline and domestic sales clearly illustrated the seasonal nature of gasoline consumption and that production in Canada is much higher than consumption. Canada exports large volumes of gasoline, primarily to the United States eastern seabord from refineries in Atlantic Canada. The trend is similar for diesel fuel. Demand for both gasoline and diesel is expected to continue to grow in 2005 as high prices have had a limited impact on demand growth. In general, the Ontario/Quebec region is short of gasoline and must import gasoline during the summer months to cover the shortfall. It was noted that motorists and homeowners who heat with oil will bear the burden of higher

Ce document rassemble les résultats obtenus au banc d'essai sur plusieurs types de moteurs représentant un assez large éventail d'applications, depuis le motoculteur utilisé en agriculture africaine jusqu'au moteur classique de tracteur ou de camion. Deux types de produits ont été examinés : les huiles végétales elles-mêmes employées pures ou en mélange au gazole, et les esters méthyliques de ces huiles utilisés tels quels. Lors d'un fonctionnement de courte durée les huiles aussi bien que les esters conduisent globalement à un fonctionnement satisfaisant du moteur; les pertes de performances par rapport au gazole restent modérées voire imperceptibles. Les seuls problèmes dans ce cas concernent la mise en oeuvre, difficile avec les huiles en raison de leur très forte viscosité, beaucoup plus aisée avec les esters. En endurance, l'inconvénient majeur des huiles végétales et de leurs dérivés concerne la formation de dépôts au nez des injecteurs. Sur les moteurs rustiques à préchambre (type Hatz ce phénomène reste limité puisqu'il a été possible de conduire, sans incident, un ensemble d'essais d'endurance de 1100 h avec différents types d'huiles pures (arachide, coton, palme. Sur les moteurs à Injection directe la formation de dépôts constitue une très sérieuse contrainte puisqu'elle conduit pratiquement à proscrire l'utilisation d'huiles même en mélange (25 ou 50 % dans le gazole.

    According to estimates of the world's uranium consumption, exploitation of most rich sources is expected by the 1980's. Forecasts show that the rate of uranium consumption will increase towards the end of the century. It is therefore desirable to exploit poor sources not yet in use. In the near future, the most reasonable source for developing uranium is phosphate rock. Uranium reserves in phosphates are estimated at a few million tons. Production of uranium from phosphates is as a by-product of phosphate rock processing and phosphoric acid production; it will then be possible to save the costs incurred in crushing and dissolving the rock when calculating uranium production costs. Estimates show that the U.S. wastes about 3,000 tons of uranium per annum in phosphoric acid based fertilisers. Studies have also been carried out in France, Yugoslavia and India. In Israel, during the 1950's, a small plant was operated in Haifa by 'Chemical and Phosphates'. Uranium processes have also been developed by linking with the extraction processes at Arad. Currently there is almost no activity on this subject because there are no large phosphoric acid plants which would enable production to take place on a reasonable scale. Discussions are taking place about the installation of a plant for phosphoric acid production utilising the 'wet process', producing 200 to 250,000 tons P 2 O 5 per annum. It is necessary to combine these facilities with uranium production plant. (author)

  17. Manual of radioisotope production

    International Nuclear Information System (INIS)

    1966-01-01

    The Manual of Radioisotope Production has been compiled primarily to help small reactor establishments which need a modest programme of radioisotope production for local requirements. It is not comprehensive, but gives guidance on essential preliminary considerations and problems that may be met in the early stages of production. References are included as an aid to the reader who wishes to seek further in the extensive literature on the subject. In preparing the Manual, which is in two parts, the Agency consulted several Member States which already have long experience in radioisotope production. An attempt has been made to condense this experience, firstly, by setting out the technical and economic considerations which govern the planning and execution of an isotope programme and, secondly, by providing experimental details of isotope production processes. Part I covers topics common to all radioisotope processing, namely, laboratory design, handling and dispensing of radioactive solutions, quality control, measurement and radiological safety. Part II contains information on the fifteen radioisotopes in most common use. These are bromine-82, cobalt-58, chromium-51, copper-64, fluorine-18, gold-198, iodine-131, iron-59, magnesium-28, potassium-42, sodium-24, phosphorus-32, sulphur-35, yttrium-90 and zinc-65. Their nuclear properties are described, references to typical applications are given and published methods of production are reviewed; also included are descriptions in detail of the production processes used at several national atomic energy organizations. No attempt has been made to distinguish the best values for nuclear data or to comment on the relative merits of production processes. Each process is presented essentially as it was described by the contributor on the understanding that critical comparisons are not necessary for processes which have been well tried in practical production for many years. The information is presented as a guide to enable

    Full Text Available This study is aimed at predicting the Sicilian potential biogas production, using the Organic Fraction of Municipal Solid Waste (OFMSW, animal manure and food industry by-products, in a region where only one biogas plant using MSW and one co-digestion plant are nowadays available. The statistical data about OFMSW, the number of animals bred in medium and large farms and the amounts of by-products of food processing industries were evaluated, in order to compute the Sicilian potential biogas and energy production. The OFMSW produced in Sicily, that is 0.8 million tons ca. per year (37% of MSW, could be used in a bio-reactor, together with other raw materials, for Anaerobic Digestion (AD process, producing biogas and “digestate”. Moreover, 3.03 million tons ca. of manure, collected in medium and large animal husbandry farms (where cows, pigs and poultry are bred, and 350 thousand tons ca. of by-products, collected in food processing industries (pomace from olive oil mills and grape marc from wineries, might be used for AD process. The Sicilian potential biogas production from the AD of the above raw materials is 170.2 millions of m3, that is equal to 1023.4 GWh of energy per year, of which 484 GWh from animal manure, 303 GWh from OFMSW and 236.4 GWh from food industry by-products. The highest biogas production is in the province of Palermo (35.6 millions of m3, Ragusa (30.8 millions of m3 and Catania (22.8 millions of m3, having a potential energy production of 213.8, 185 and 137 GWh, respectively.

    1994-03-01

    Technology per se does not provide a competitive advantage. Timely exploitation of technology is what gives the competitive edge, and this demands a major shift in the product development process and management of the industrial enterprise. `Teaming to win' is more than a management theme; it is the disciplined engineering practice that is essential to success in today's global marketplace. Teaming supports the concurrent engineering practices required to integrate the activities of people responsible for product realization through achievement of shorter development cycles, lower costs, and defect-free products.

  1. Versioning of printed products

    Science.gov (United States)

    Tuijn, Chris

    2005-01-01

    During the definition of a printed product in an MIS system, a lot of attention is paid to the production process. The MIS systems typically gather all process-related parameters at such a level of detail that they can determine what the exact cost will be to make a specific product. This information can then be used to make a quote for the customer. Considerably less attention is paid to the content of the products since this does not have an immediate impact on the production costs (assuming that the number of inks or plates is known in advance). The content management is typically carried out either by the prepress systems themselves or by dedicated workflow servers uniting all people that contribute to the manufacturing of a printed product. Special care must be taken when considering versioned products. With versioned products we here mean distinct products that have a number of pages or page layers in common. Typical examples are comic books that have to be printed in different languages. In this case, the color plates can be shared over the different versions and the black plate will be different. Other examples are nation-wide magazines or newspapers that have an area with regional pages or advertising leaflets in different languages or currencies. When considering versioned products, the content will become an important cost factor. First of all, the content management (and associated proofing and approval cycles) becomes much more complex and, therefore, the risk that mistakes will be made increases considerably. Secondly, the real production costs are very much content-dependent because the content will determine whether plates can be shared across different versions or not and how many press runs will be needed. In this paper, we will present a way to manage different versions of a printed product. First, we will introduce a data model for version management. Next, we will show how the content of the different versions can be supplied by the customer

  7. Will marine productivity wane?

    Science.gov (United States)

    Laufkötter, Charlotte; Gruber, Nicolas

    2018-03-01

    If marine algae are impaired severely by global climate change, the resulting reduction in marine primary production would strongly affect marine life and the ocean's biological pump that sequesters substantial amounts of atmospheric carbon dioxide in the ocean's interior. Most studies, including the latest generation of Earth system models, project only moderate global decreases in biological production until 2100 (1, 2), suggesting that these concerns are unwarranted. But on page 1139 of this issue, Moore et al. (3) show that this conclusion might be shortsighted and that there may be much larger long-term changes in ocean productivity than previously appreciated.

    We study operators acting on a tensor product Hilbert space and investigate their product numerical range, product numerical radius and separable numerical range. Concrete bounds for the product numerical range for Hermitian operators are derived. Product numerical range of a non-Hermitian operator forms a subset of the standard numerical range containing the barycenter of the spectrum. While the latter set is convex, the product range needs not to be convex nor simply connected. The product ...

Heating at 50°C during 20 h maximum and pH 7 and pH 9 were used in all tests. The higher activity was found in WPC glycosylates products with ribose at pH 7 and heating during 10–15 h. In comparable form, antioxidant activity in WPCH was incremented by prior hydrolysis to glycation with 25–45% of hydrolysis degree. Further functional properties of whey proteins (solubility, emulsion, and foam were also improved by the polymerization with ribose. The color of polymerized products due to Maillard reactions was associated with antioxidant activity of each compound; however comparative color in glycosylates products with glucose and ribose did not show this effect.

    Present situation of utilizing the radioactive consumer products and exposure dose were reviewed with published data. Practically, consumer products are divided into three categories, (1) radioactive nuclides intentionally incorporated into radioluminous dye, ionization chambers for smoke detector, eliminator of static electricity, and glow lamp (2) natural radioactive nuclides contained in false teeth, porcelain, glass, and gas mantle (3) natural radioactive nuclides accumulated as industrial waste at the consumption of coal, petroleum, and natural gas or in fertilizer and materials for construction.

    This invention relates to a process for the production of tritium by subjecting comminuted solid lithium fluoride containing the lithium isotope of atomic mass number 6 to neutron radiation in a self-sustaining neutronic reactor. The lithium fiuoride is heated to above 450 deg C. in an evacuated vacuum-tight container during radiation. Gaseous radiation products are withdrawn and passed through a palladium barrier to recover tritium. (AEC)

    Resource productivity, measured as GDP output per resource input, is a widespread sustainability indicator combining economic and environmental information. Resource productivity is ubiquitous, from the IPAT identity to the analysis of dematerialization trends and policy goals. High resource productivity is interpreted as the sign of a resource-efficient, and hence more sustainable, economy. Its inverse, resource intensity (resource per GDP) has the reverse behavior, with higher values indicating environmentally inefficient economies. In this study, we investigate the global systematic relationship between material, energy and carbon productivities, and economic activity. We demonstrate that different types of materials and energy exhibit fundamentally different behaviors, depending on their international income elasticities of consumption. Biomass is completely inelastic, whereas fossil fuels tend to scale proportionally with income. Total materials or energy, as aggregates, have intermediate behavior, depending on the share of fossil fuels and other elastic resources. We show that a small inelastic share is sufficient for the total resource productivity to be significantly correlated with income. Our analysis calls into question the interpretation of resource productivity as a sustainability indicator. We conclude with suggestions for potential alternatives.

  11. Particle production by neutrinos

    1979-01-01

    A review is given of particle production by neutrinos in charged-current inclusive and exclusive channels. The production rates for various particles in neutrino-nucleon interactions at a beam energy of 25 GeV are compared. The mesons are, of course, dominated by pion production. The p 0 (760) rate is an order of magnitude smaller. Strange and charm pseudoscalar mesons are a further factor of two down in rate. The strange vector mesons are suppressed by more than an order of magnitude relative to K 0 production; however, the charmed D* + (2010) is only a factor of two smaller in rate than the D 0 (1860). With regards to the baryons, most of them are, of course, nucleons. The Λ 0 and Y*(1385) rates are down by one and two orders of magnitudes, respectively. The lower limit on the charmed Σ/sub c/ ++ baryon rate is similar to the Y*(1385) rate. Finally, the quasielastic and one-pion production exclusive channels have about the same cross section as that of the D* + ; associated production of strange particles in the νn → μ - K + Λ channel and the ΔS = +ΔΩ process νp → μ - pK + are down by factors of five and twenty, respectively, compared to the quasielastic cross section

    Despite decades of industry innovation and regulatory efforts, the harmfulness of conventional cigarettes has not changed. There are several pitfalls in this area, including the long time lag before health impacts of product regulatory changes become apparent, the danger of consumers deriving false reassurance of lesser harm in the interim period, the lack of relevant expertise and the lack of an internationally agreed and evidence-based strategic approach. Articles 9 and 10 of the Framework Convention on Tobacco Control provide the potential for such a global strategy, and knowledge and research has increased significantly over recent years. However, there are huge opportunity costs in implementing product disclosure and regulatory strategies: most national regulators have very limited human and financial resources, which should be focused on other evidence-based tobacco control interventions. We believe therefore that it is now time to abandon the notion of safe or safer cigarettes while moving consumers towards cleaner nicotine products as soon as possible. In parallel to this, we recommend a number of other strategies be implemented including: reducing the appeal of all tobacco products, forbidding new tobacco products or brand variants being marketed without evidence of reduced harm, appeal or addictiveness, and developing a tobacco industry resourced, but industry independent, Framework Convention on Tobacco Control global repository to assist national regulators in understanding and regulating the products on their markets.

    A continuous, four stage fluidized bed process for converting uranium hexafluoride (UF 6 ) to ceramic-grade uranium dioxide (UO 2 ) powder suitable for use in the manufacture of fuel pellets for nuclear reactors is disclosed. The process comprises the steps of first reacting UF 6 with steam in a first fluidized bed, preferably at about 550 0 C, to form solid intermediate reaction products UO 2 F 2 , U 3 O 8 and an off-gas including hydrogen fluoride (HF). The solid intermediate reaction products are conveyed to a second fluidized bed reactor at which the mol fraction of HF is controlled at low levels in order to prevent the formation of uranium tetrafluoride (UF 4 ). The first intermediate reaction products are reacted in the second fluidized bed with steam and hydrogen at a temperature of about 630 0 C. The second intermediate reaction product including uranium dioxide (UO 2 ) is conveyed to a third fluidized bed reactor and reacted with additional steam and hydrogen at a temperature of about 650 0 C producing a reaction product consisting essentially of uranium dioxide having an oxygen-uranium ratio of about 2 and a low residual fluoride content. This product is then conveyed to a fourth fluidized bed wherein a mixture of air and preheated nitrogen is introduced in order to further reduce the fluoride content of the UO 2 and increase the oxygen-uranium ratio to about 2.25

    The meat industry has met new challenges since the World Health Organization classified processed meat in carcinogenic Group 1. In relation to this, the functional food concept in meat processing has gained importance, especially in reducing carcinogenic N-nitroso compounds and polycyclic aromatic hydrocarbons (PAHs) as an additional imperative, apart from the usual fat and salt reduction and product enrichment with functional ingredients. PAH reduction relies on control of the smoking process, but there is also a possibility they could be degraded by means of probiotic microorganisms or spices. The reduction of N-nitroso compounds could be provided by lowering the amount of added nitrite/nitrate, using substitutes for these chemicals, and/or by preventing conditions for the creation of N-nitroso compounds. Nevertheless, fat and salt reductions still remain topical, and rely mostly on the use of functional ingredients as their substitutes.

  17. Biodiesel production technologies: review

    2017-05-01

    Full Text Available Biodiesel is a fuel with various benefits over the conventional diesel fuel. It is derived from renewable resources, it has less emission to environment, it is biodegradable so has very limited toxicity and above all its production can be decentralized so that it could have a potential in helping rural economies. However, there are also some worth mentioning challenges associated with production of biodiesel. Among them repeatedly mentioned are the cost of feedstock and the choice of convenient technology for efficient production of the fuel from diverse feedstock types. There are four main routes by which raw vegetable oil and/or animal fat can be made suitable for use as substituent fuel in diesel engines without modification. These are direct use or blending of oils, micro-emulsion, thermal cracking or pyrolysis and transesterification reaction. Due to the quality of the fuel produced, the transesterification method is the most preferred way to produce biodiesel from diverse feedstock types. Through this method, oils and fats (triglycerides are converted to their alkyl esters with reduced viscosity to near diesel fuel levels. There are different techniques to carry out transesterification reaction for biodiesel production. Each technique has its own advantages and disadvantages as well as its own specifically convenient feedstock character. There are also some very important reaction conditions to be given due attention in each of this techniques for efficient production of biodiesel, such as molar ratio of alcohol to oil, type and amount of catalyst, reaction temperature, reaction time, reaction medium, type and relative amount of solvents, among others. This review is meant to investigate the main transesterification techniques for biodiesel production in terms of their choice of feedstock character as well as their determinately required reaction conditions for efficient biodiesel production, so that to give an overview on their advantages

    Characterization of smoke, factors influencing smoke production and experimental methods for measuring smoke production are discussed in this literature review. Recent test-based correlation models are also discussed. Despite the large number of laboratories using different fire testing methods, published smoke data have been scarce. Most technical literature on smoke production from building materials is about experimental results in small scale tests. Compilations from cone calorimeter tests have been published for a few materials, e.g. upholstered furniture materials and some building products. Mass optical density data and compilations of gravimetric soot data are available for various materials as well as a number of smoke obscuration values. For a given material often a wide range of values of smoke output can be found in the literature and care should be exercised in applying the appropriate value in each case. In laboratory experiments, the production of smoke and its optical properties are often measured simultaneously with other fire properties as heat release and flame spread. The measurements are usually dynamic in full scale, i.e. they are performed in a flow-through system. In small scale they may be either dynamic, as in the cone calorimeter, or static, i.e. the smoke is accumulated in a closed box. Small-scale tests are necessary as practical tools. Full-scale tests are generally considered to be more reliable and are needed to validitate the small-scale tests

    Launching a new product can be a tense time for a small or large business. There are those moments when you wonder if all of the work done to develop the product will pay off in revenue, but there are many things are can do to help increase the likelihood of a successful product launch. An open-minded consumer-oriented approach is imperative in todayís diverse global marketplace so a firm can identify and serve its target market, minimize dissatisfaction, and stay ahead of competitors. Final consumers purchase for personal, family, or household use. Finally, the kind of information that the marketing team needs to provide customers in different buying situations. In high-involvement decisions, the marketer needs to provide a good deal of information about the positive consequences of buying. The sales force may need to stress the important attributes of the product, the advantages compared with the competition; and maybe even encourage ìtrialî or ìsamplingî of the product in the hope of securing the sale. The final stage is the post-purchase evaluation of the decision. It is common for customers to experience concerns after making a purchase decision. This arises from a concept that is known as ìcognitive dissonance

    In this work, various kinds of catalysts including a nanosize TiO2 (nTiO 2 ) were examined in respect to the efficiency of H2 production by gamma rays.The different activity of catalysts was characterized by X-ray powder diffraction (XRD) and electron paramagnetic resonance (EPR). A combination of EPR and spin-trapping method was also used to detect unstable radicals such as hydroxyl radicals and hydrogen atoms to investigate the effect of catalysts and additives on the efficiency of H2 production. A nanosize TiO 2 (nTiO 2 ) catalyst that showed an excellent activity in the production of H2 from water by gamma rays were examined in respect to the efficiency of H2 production with concomitant treatment of metal-EDTA complexes that are main wastes of chemical cleaning wastewater. As a result, among the catalysts examined in this work, a nanosize TiO2 (nTiO 2 ) showed the most efficient H2 production and the efficiency increased upon reapplication. This catalyst was also successfully used to produce H2 with concomitant treatment of metal-EDTA complexes

    The history of uranium production in Sweden is reviewed in the article. The World War II led to an exploitation of the Swedish alum shale on a large scale. In the last phase of the war it also became obvious that the shale might be used for energy production of quite another kind than oil. In 1947 AB Atom energy was founded, an enterprise with one of its purposes to extract uranium for peaceful use. A plant with a yearly capacity of 120 tons of uranium was erected at Ranstad and ready for production by 1965. From the start in Ranstad and for many years to come there was hardly any interest in an immediate large uranium production. It was decided to use the plant for studies on its more effective exploitation in case of an expansion in the future, bearing in mind the reactor programme. In the course of time economical reasons began to speak against the project. The shale seemed to have a future neither as oil nor as uranium resource. The complete termination of the work on uranium production from shale occurred in 1989

  4. Optimizing kaon production

    International Nuclear Information System (INIS)

    Berley, D.

    1976-01-01

    Kaon production data is examined with the view toward producing high quality beams in the future. Emphasis is placed upon the low momentum region, below 1 GeV/c, where the behavior of the kaon momentum spectrum is shown to be dominated by strongly momentum dependent kinematic factors. No complete experimental survey of production cross sections at different incident proton energies exists from a single apparatus. Information on relative production yields for different proton energies is important in the choice of parameters for an accelerator constructed primarily as a source of kaons. Data from different accelerators do exist and have been compiled. The key element in understanding how to present the data from different laboratories in a consistent way is an analysis of the effects of target material, target size, and production angle. This analysis not only enables a unification of the data but also indicates simple, useful and powerful principles about optimizing target efficiency. A summary is presented of existing kaon production facilities in the United States. These are all at proton accelerators. The possibility of using electron accelerators as kaon sources is examined. It is found that secondary beam fluxes can be obtained at electron linacs which are comparable to those obtained at proton synchrotrons

    Full Text Available The sales of appropriate merchandise is essential for performance of every retail enterprise. The way that products are displayed within retail sales object will be in so much important as the merchandise is considered a pad of the perceived image of that outlet. Thus, assorted products speak to their consumers as far as to what they [the consumers] can expect, and they signal off a number of marketing messages as well. Merchandising is the key element in attracting the consumers and in encouraging of repeated purchases. The question then could be: products or services?, yet the retailer's future will depend on his ability to develop the best sale offers. The selection of appropriate merchandise, and that would be the one [merchandise] that is in accordance with outlet's image, requires careful planning which, again, needs to be related with the direction the seller is following. Managing of the product assortments' dimensions emerges from the retailer's strategic planning, therefore, the decisions made on the inclusion of novel products as well as about deleting of the old stock are deemed (to be strategic.

  7. Oil production system

    Ballantyne, J F

    1983-12-21

    A new oil producing system is proposed which consists of a group of underwater wells, an underwater riser and a floating storage facility for the production of the wells. The group of wells and the riser are interconnected through a manifold system in such a way that the production from any well or from the entire group of wells go to the base (foundation) of the riser. From above the riser is connected with the floating storage facility which is equipped, besides tanks for storing the well products, with a separation device for separating the oil and the accompanying gas. The gas is used as a fuel for producing electric power required by the dynamic positioning systems. The products from each well are tested by means of a regulable coupling controlled by means of a cable, which is passed from the surface through the riser. The wellhead equipment for the unslanted wells is mounted on a template previously installed on the sea floor. From the template the well products enter the riser through the manifold unit system.

    2008-01-01

    A review of recent measurements of beauty production, based on proton antiproton collision data at √s = 1.96 TeV and using the CDF detector, is given. Previous measurements of beauty (b) quark production at the Tevatron, carried out at centre-of-mass energies √s = 1.8 TeV, have shown discrepancies when compared to Next to Leading Order (NLO) predictions [1]. Improved predictions and experimental procedures have reduced this discrepancy [2]. Improved parton density functions, better fragmentation functions and more complete theoretical calculations have improved theoretical accuracy. Experimentally, measurements of beauty production at √s = 1.96 TeV are now presented in terms of b hadrons or B mesons, to avoid problems unfolding back to the quark level. In this review [3] measurements of inclusive beauty (where one beauty jet or hadron is reconstructed in the event), and beauty + X (where X can be a boson or another beauty jet or hadron), production will be presented: inclusive beauty jet cross-section; semi and fully reconstructed B meson cross-section; beauty dijet cross-section; semi-reconstructed B B meson cross-section; Z boson + beauty jet cross-section. More information concerning other measurements of heavy quark production can be found elsewhere [4

    A wide range of products can be manufactured from the following materials: (1) lunar regolith or basalt; (2) regolith or rock beneficiated to concentrate plagioclase or other minerals; (3) iron, extracted from lunar soil or rocks by various means; (4) naturally occurring or easily obtained materials that have cementitious properties; and (5) byproducts of the above materials. Among the products that can be produced from these materials are the following: beams; plates and sheets; transparent plates (windows); bricks and blocks; pipes and tubes; low-density materials (foams); fiber, wire, and cables; foils and reflective coatings; hermetic seals (coatings); and formed objects. In addition to oxygen, which can be obtained by several processes, either from unbeneficiated regolith or by reduction of concentrated ilmenite, these materials make the simplest requirements of the lunar resource extraction system. A thorough analysis of the impact of these simplest products on the economics of space operations is not possible at this point. Research is necessary both to define optimum techniques and adapt them to space and to determine the probable market for the products so that the priority of various processes can be assessed. Discussions of the following products are presented: aerobraking heat shields; pressurized habitats; lunar photovoltaic farms; and agricultural systems.

    Acrylonitrile (ACN) is a petroleum-derived compound used in resins, polymers, acrylics, and carbon fiber. We present a process for renewable ACN production using 3-hydroxypropionic acid (3-HP), which can be produced microbially from sugars. The process achieves ACN molar yields exceeding 90% from ethyl 3-hydroxypropanoate (ethyl 3-HP) via dehydration and nitrilation with ammonia over an inexpensive titanium dioxide solid acid catalyst. We further describe an integrated process modeled at scale that is based on this chemistry and achieves near-quantitative ACN yields (98 +/- 2%) from ethyl acrylate. This endothermic approach eliminates runaway reaction hazards and achieves higher yields than the standard propylene ammoxidation process. Avoidance of hydrogen cyanide as a by-product also improves process safety and mitigates product handling requirements.

Shelf life is directly associated with the staling process, which depends on the composition of bakery products and important are storage conditions as well. In the article are described particular components (starch, nonstarch polysacharides, water and how they affect the staling process. Generally during staling of bakery products occur  processes related with starch retrogradation, moisture redistribution from the crumb to the crust and other interactions between components. Staling process could be delayed by using various bakery improvers like enzymes, hydrocolloids, emulgators and other compounds. Also useful is the application of suitable packaging techniques.doi:10.5219/124

The fluid enacted the multiplicity of Production thus making it more difficult to be organised because there were...... in opposite directions. They are all part of the fluid object. There is no single chain of circulating references that makes the object a matter of fact. Accounting fluidity means that references drift back and forth and enact new realities also connected to the chain. In this setting future research may......This paper is about objects. It follows post ANT trajectories and finds that objects are multiple and fluid. Extant classic ANT inspired accounting research largely sees accounting inscriptions as immutable mobiles. Although multiplicity of objects upon which accounting acts has been explored...

    The increase in global temperatures caused by rising CO2 levels necessitates the development of alternative sources of fuel and chemicals. One appealing alternative that has been receiving increased attention in recent years is the photosynthetic conversion of atmospheric CO2 to biofuels and chemical products using genetically engineered cyanobacteria. This can help to not only provide an alternate "greener" source for some of the most popular petroleum based products but it can also help to reduce atmospheric CO2. Utilizing cyanobacteria rather than plants allows for reduced land requirements and reduces competition with food crops. This review discusses advancements in the field since 2012 with a particular emphasis on production of hydrocarbons. Copyright © 2016 Elsevier B.V. All rights reserved.

  16. Productivity and Institutions

    Full Text Available Differences in productivity account for differences in output per capita between countries as well as changes in output and the standard of living for each country over long periods of time. During the first industrial revolution, one could already see the emergence of two groups of countries: the high- and the low-GDP per capita countries. The list of countries belonging to the highproductivity group has not changed much over the past century. Differences in institutions separate the two clubs. The high-productivity group is, amongst many other differences, characterized by less corruption, a better legal system, superior enforcement of contracts, a lower cost of starting a business and lower tariffs. Historical output series for Britain going back to the mid-19th century show that productivity has increased greatly and improved the standard of living.

    Grandfield, J. F.

    The technology related to the production of remelt ingots (small ingots, sows and T-Bar) is reviewed. Open mold conveyors, sow casting, wheel and belt casting and VDC and HDC casting are described and compared. Process economics, capacity, product quality and process problems are listed. Trends in casting machine technology such as longer open mold conveyor lines are highlighted. Safety issues related to the operation of these processes are discussed. The advantages and disadvantages of the various machine configurations and options e.g. such as dry filling with the mold out of water and wet filling with the mold in water for open mould conveyors are discussed. The effect of mold design on machine productivity, mold cracking and mold life is also examined.

    Energy Production Systems Engineering presents IEEE, Electrical Apparatus Service Association (EASA), and International Electrotechnical Commission (IEC) standards of engineering systems and equipment in utility electric generation stations. Electrical engineers that practice in the energy industry must understand the specific characteristics of electrical and mechanical equipment commonly applied to energy production and conversion processes, including the mechanical and chemical processes involved, in order to design, operate and maintain electrical systems that support and enable these processes. To aid this understanding, Energy Production Systems Engineeringdescribes the equipment and systems found in various types of utility electric generation stations. This information is accompanied by examples and practice problems. It also addresses common issues of electrical safety that arise in electric generation stations.

    This paper contributes to the analysis of the impact of externalities on the host country's total factor productivity by taking into account different dimensions of spillover effects. Namely, engagement in exporting and foreign ownership is generally perceived as being beneficial to individual...... firms and the economy as a whole. The approach used in the current research accounts for different internal as well as external factors that individual firms face and evaluates the effect on changes in productivity, technology as well as the efficiency of domestic firms. The empirical analysis focuses...... on Hungary. While the country leads the group of post-socialist countries in the amount of attracted foreign direct investments (FDI) the effect of this policy on the economy remains unclear. The research finds that different externalities play a different role in productivity, technological and efficiency...
