    Full Text Available O presente trabalho teve como objetivo a obtenção de isotermas de dessorção de filés de bonito (Sarda sarda, previamente salgados a vácuo e defumados com fumaça líquida. As isotermas foram obtidas a quatro temperaturas (5, 25, 40 e 60 ºC em condições de dessorção, através do método gravimétrico estático, com soluções salinas saturadas. Os dados experimentais foram ajustados a quatro modelos da literatura (BET linearizado, GAB, Henderson e Oswin modificado. Os resultados mostraram que as isotermas tomaram forma sigmoidal de tipo II e que o modelo de Guggenheim-Anderson-deBoer (GAB foi aceitável para modelar os dados experimentais. O calor isostérico de dessorção, um parâmetro necessário para simular e projetar adequadamente o secador, também foi calculado e pode ser representado através de um modelo matemático simples, em função da umidade de equilíbrio.The main objetive of this work was to obtain the desorption isotherms of Atlantic bonito (Sarda sarda fillets, previously subjected to an immersion impregnation process with NaCl solutions and smoked in liquid smoke. The isotherms were obtained at four temperatures (5, 25, 40 and 60 ºC, using the static method with saturated salt solutions. The experimental data were fitted to four models (linearized BET, GAB, Henderson and modified Oswin. The results showed that a type II sigmoidal isotherm, with GAB equation, gave the best fit. The isosteric heat of desorption was also calculated and a simple empirical equation has been proposed to represent this heat, as a function of equilibrium moisture content.

    During the second semester of 2009, three trips were made from Olhão (Southern Portugal) to Stralsund (Northern Germany) carrying 2.122 animals, which included multiple teleosts, elasmobranchs and invertebrates. This group included scombrids, such as 1.869 Scomber japonicus and 9 Sarda sarda, which are notoriously difficult to transport. However, multiple adaptations to transport regimes adopted regularly have allowed the authors to successfully move these animals by road and air over a total of up to 25 hr. Such adaptations included maintaining oxygen saturation rates at approximately 200%, and also the constant addition of AmQuel(®) , sodium bicarbonate, and sodium carbonate. Different formulations were used during the three trips, with the best results corresponding to 20/30/30 ppm of the three aforementioned chemicals, respectively. The authors suggest, however, that a modified formula of 20/40/40 ppm will allow for an even more stable pH on future trips. © 2010 Wiley-Liss, Inc.

    Spot and Runway Departure Advisor (SARDA) is a decision support tool to assist airline ramp controllers and ATC tower controllers to manage traffic on the airport surface to significantly improve efficiency and predictability in surface operations. The core function of the tool is the runway scheduler which generates an optimal solution for runway sequence and schedule of departure aircraft, which would minimize system delay and maximize runway throughput. The presentation also discusses the latest status of NASA's current surface research through a collaboration with an airline partner, where a tool is developed for airline ramp operators to assist departure pushback operations. The presentation describes the concept of the SARDA tool and results from human-in-the-loop simulations conducted in 2012 for Dallas-Ft. Worth International Airport and 2014 for Charlotte airport ramp tower.

    There is a pressing need for the development of ways of preparing palatable salt-reduced foods to reduce the salt intake of the Japanese population. The salt-reducing effect of the characteristic flavors other than umami of dried bonito stock, which is widely used in everyday Japanese food, was examined by sensory evaluation. In the 1st sensory evaluation, the effect was evaluated in a model solution. The saltiness of 0.80% NaCl solution was equivalent to that of 0.12% monosodium glutamate (MSG) solution containing 0.81% NaCl and dried bonito stock containing 0.68% NaCl. Saltiness enhancement could not be found when MSG solution was used, but was found with 6% dried bonito stock. The 2nd evaluation examined whether the effect was valid for 2 everyday Japanese foods--traditional Japanese clear soup (sumashi-jiru) and steamed egg custard (tamagodoufu). Although enhancement of saltiness by dried bonito stock could not be clearly demonstrated in the soup, a change in NaCl concentration within 15% did not affect the palatability of the soup. However, dried bonito stock not only enhanced the saltiness but also improved the palatability of steamed egg custard. These findings are expected to be useful for improving the palatability of salt-reduced food.

    Full Text Available Leukocytes subpopulations in blood and milk of lactating Sarda ewes were investigated. Animals characterized by a SSC level <500×103cells/mL and a negative bacteriological examination were sampled in early, mid and late lactation. Milk differential cell count evidenced that macrophage represented the main population (42.8%±3.5 followed by lymphocytes (40.2%±3.4 and neutrophils (8,6%±2.1. Flow cytometry analysis showed that lymphocytes subsets in milk were quite different from blood. High CD8+ and low CD4+ lymphocytes percentages determined a CD4/CD8 ratio inversion in milk compared to blood (0.3%±0.03 vs 1.8%±0.08. CD8+ decreased while, conversely, CD4+ increased in late lactation. γδ T cells were more represented in milk (12.6%±1.3 than in blood (6.8%±0.3 and their proportions appeared similar throughout lactation in both compartments. IL-2 receptor was mainly expressed in milk on T cytotoxic lymphocytes. Data obtained in uninfected mammary glands could allow an early discrimination between physiological and pathological changes occurring in ewe milk. Further phenotypical and functional studies on milk leukocytes subsets might help to understand defense mechanisms of the ovine mammary gland against IMI.

    Full Text Available In Sardinia, goat farming is a very important resource. Sarda and Maltese breed are reared mainly for milk production and for suckling kids meat, while meat from adult goats is undervalued. The use of adult goat meat to obtain ripened ham will contribute to safeguard the Sardinian goat supply chain. The aim of the present study was to characterize Sarda and Maltese goat dry ham in order to evaluate the quality of autochthonous goat breed meat. Chemical-physical characteristics were determined dur-ing the production stages, while the rheological and colour parameters and the composition of the goat ham were determined at the end of ripening. The pH evolution during processing were similar to other cured meat products, e.g. sheep hams, even though the values were high, especially in the products from Sarda breed. The aw value regularly decreased during processing. Colour parameters (L*, a*, b* in the hams from Maltese goat breed were significantly (P<0.05 higher than in those from Sarda. The Sarda goat ham showed a significantly lower percentage of moisture (42% vs 52%, an higher protein content (44.35% vs 34.19%, while no differences were pointed out in the total fat content. Among the ham rheological properties, hardness parameters showed higher levels (13850.22±7589.92 vs 11073.99±6481.31, respectively in Sarda and Maltese hams in comparison to similar products from pork and sheep, while adhesiveness value was lower. The results show that the quality parameters of goat ripened hams are affected mainly by the charac-teristics of the goat meat, in relation on the breed and the breeding system, and, less, by the traditional technology.

    Surface operations at airports in the US are based on tactical operations, where departure aircraft primarily queue up and wait at the departure runways. NASAs Spot And Runway Departure Advisor (SARDA) tool was developed to address these inefficiencies through Air Traffic Control Tower advisories. The SARDA system is being updated to include collaborative gate hold, either tactically or strategically. This paper presents the results of the human-in-the-loop evaluation of the tactical gate hold version of SARDA in a 360 degree simulated tower setting. The simulations were conducted for the east side of the Dallas-Fort Worth airport. The new system provides gate hold, ground controller and local controller advisories based on a single scheduler. Simulations were conducted with SARDA on and off, the off case reflecting current day operations with no gate hold. Scenarios based on medium (1.2x current levels) and heavy (1.5x current levels) traffic were explored. Data collected from the simulation was analyzed for runway usage, delay for departures and arrivals, and fuel consumption. Further, Traffic Management Initiatives were introduced for a subset of the aircraft. Results indicated that runway usage did not change with the use of SARDA, i.e., there was no loss in runway throughput as compared to baseline. Taxiing delay was significantly reduced with the use of advisory by 45 in medium scenarios and 60 in heavy. Arrival delay was unaffected by the use of advisory. Total fuel consumption was also reduced by 23 in medium traffic and 33 in heavy. TMI compliance appeared unaffected by the advisory.

    Full Text Available Goat farming is a very important resource, expecially in marginal and unlikely exploitable Mediterranean areas. They are extensively reared, mainly for milk production and for suckling kids meat. The meat from adult goats instead is not profitable, because of its very low commercial value. The transformation of the Sarda goat (native breed meat in ripened products (ham would contribute to safeguard the Sardinian goat supply chain. In the present study, in order to characterize the Sarda breed goat dry ham, five batches (L1–L5, processed in a traditional plant, were analyzed. The chemical-physical characteristics were determined in the following stages: fresh ham (MP, after salting (S, after drying (E and at the end of ripening (P. The microbiological parameters were determined in MP and in P. The dynamics of pH during processing were similar to those of cured meat products (in P: 6.58±0.26. The aw value decreased during the processing up to 0.79±0.03. Regarding the microbiological parameters, in P the coagulase negative Staphylococci were the prevalent flora (4.38±1.08 Log10 cfu/g, followed by the Lactic acid bacteria (2.46±1.00. The Moulds and Yeasts were not constant and the presence of pathogens was not highlighted.

    Spot and Runway Departure Advisor (SARDA) is a proposed decision-support tool for air traffic control tower controllers for reducing taxi delay and optimizing the departure sequence. In the present study, the tool's usability was evaluated to ensure that its claimed performance benefits are not being realized at the cost of increasing the work burden on controllers. For the evaluation, workload ratings and questionnaire responses collected during a human-in-the-loop simulation experiment were analyzed to assess the SARDA advisories' effects on the controllers' ratings on cognitive resources (e.g., workload, spare attention) and satisfaction. The results showed that SARDA reduced the controllers' workload and increased their spare attention. It also made workload and attention levels less susceptible to the effects of increases in the traffic load. The questionnaire responses suggested that the controllers generally were satisfied with the ease of use of the tool and the objectives of the SARDA concept, but with some caution. To gain more trust from controllers, the the reasoning behind advisories may need to be made more transparent to them.

    Recent discoveries of oil in microbial carbonate rocks have directed studies into tufas and travertines because of their great similarities with the reservoir rocks of the Aptian Pre-Salt. Tufas are continental carbonate rocks precipitated from a bicarbonate fluid at environment temperature. The genesis of tufas is related to physical, chemical, and biological processes. Here, we present a study of a modern tufa samples belong to the Serra da Bodoquena Formation - Bonito, Brazil, which is located in a special climatic regime where a well-defined seasonal cycle of wet and dry conditions occurs. This area was examined with purpose to understand the chemical conditions of the depositional environment and microorganisms involved in their formation. Field descriptions provided the following facies: i) phytoherm, formed by the accumulation of leaves, branch fragments and bryophytes cushions; ii) shrubs that are radii-fibers structures related to crystallization processes of bacteria filaments; and, iii) stromatolites, made by intercalation of laminas of micrite and shrubs. Pools, barriers and cascade/waterfall were identified as the main depositional environment, which are included to the fluvial depositional model. SEM images showed several cyanobacterial filaments. Organic composition showed the presence of n-alkanes and sterols. Results of XRD and XRF indicate the presence of calcite and, locally, quartz. A depletion of the δ18O indicates a fluid of meteoric origin, which is compatible with the literature for tufas. The presence of cyanobacteria and other photosynthetic organisms, besides the influence of light carbon soil is related with low values of δ13C. Palynological analysis revealed palynomorphs of fungus, hyphae, pteridophyte spores and pollen grains, which indicate a humid environment with abundant vegetation, typical of tropical climate. In conclusion, the biomineralization process, characterized by the variations of the physico-chemical conditions in this

    2002-01-01

    Full Text Available O livro Os parceiros do Rio Bonito traz uma contribuição admirável ao pensamento social brasileiro por sua relevância ético-política, como obra de denúncia política e crítica social; por sua contribuição formal ou estética, uma fina arquitetura da palavra e da argumentação sociológica e antropológica; e por sua contribuição metodológica, a pertinência do ato crítico aberto e pautado pela fluidez, em contraposição à adesão irrestrita a determinado aparato teórico. À atitude crítica associa-se a atitude mental de empatia pelo objeto, que se afasta de um frio e distante "sociologismo", mas, ao mesmo tempo, se recusa a atribuir-lhe as características que "gostaríamos" que tivesse, conforme a ideologia ou as crenças que partilhamos. A radicalidade dessa obra reside no espírito aberto para a "aventura sociológica", daí resultando a inexistência de "manifestos"ou "normas" de conduta. Todavia, Candido demarca os limites entre o espírito aberto à diversidade e à versatilidade no trato do fenômeno social, de um lado, e a adesão aventureira a um relativismo estéril, de outro. Finalmente, discute-se aqui a íntima relação entre a conduta intelectual do autor - sua postura ética diante do mundo acadêmico - e sua própria obra.

    Full Text Available Two Italian sheep breeds – Gentile di Puglia and Sopravissana – have undergone a consistent decline in numbers and have been widely substituted by the Sarda breed, which gives higher milk yield. With the aim to provide a basis for con- servation decisions, the genetic variability of the three breeds was investigated in this study. DNA of 60 animals was PCR amplified at the following microsatellite loci: CSSM43, CSSM47, CSSM60, TGLA110, TGLA122, TGLA126, TGLA377, ETH3, ETH10, ETH225, NRAMP1, OARCP20 and SPS115. Allele frequencies, gene diversity and genetic distances were calculat- ed. The highest differences in allele frequencies were found at the following loci: TGLA377, TGLA122, NRAMP1, OARCP20 and ETH3, while at the other loci the most frequent alleles were the same. The average inbreeding rate was 0.156 in the Gentile di Puglia, 0.158 in the Sopravissana and 0.137 in the Sarda. Average gene diversity of the analysed microsatel- lites was 0.59. Genetic distance between Gentile di Puglia and Sopravissana (0.081 indicates moderate differentiation; distances between the Sarda and the endangered breeds – 0.111 from the Gentile di Puglia and 0.107 from the Sopravissana - indicate a medium-high differentiation rate. The disappearance of the two less productive breeds would entail a consistent loss of genetic diversity. The inbreeding values are low enough to allow the implementation of sound conservation programmes.

    Katsuobushi is a dried, smoked and fermented bonito used in Japanese cuisine. During the fermentation process with several Aspergillus species, the colour of Katsuobushi gradually changes from a dark reddish-brown derived from haem proteins to pale pink. The change in colour gives Katsuobushi a higher ranking and price. This study aimed to elucidate the mechanism of decolourisation of Katsuobushi. A decolourising factor from the culture supernatant of Aspergillus (Eurotium) repens strain MK82 was purified to homogeneity. The purification was monitored by measuring the decolourising activity using equine myoglobin and bovine haemoglobin as substrates. It was found that the decolourising factor had protease activity towards myoglobin and haemoglobin. Complete inhibition of the enzyme by the inhibitor pepstatin A and the internal amino acid sequence classified the protein as an aspartic protease. The enzyme limitedly hydrolysed myoglobin between 1-Met and 2-Gly, 43-Lys and 44-Phe, and 70-Leu and 71-Thr. The purified enzyme decolourised blood of Katsuwonus pelamis (bonito) and a slice of dried bonito. It is proposed that aspartic protease plays a role in the decolourisation of Katsuobushi by the hydrolysis of haem proteins that allows the released haem to aggregate in the dried bonito. © 2012 Society of Chemical Industry.

Therefore, the management of side effects is essential for the longer period of continuous medication. Among the various side effects, hand–foot syndrome (HFS is the most common, occurring in 30%–50% of patients, and often results in discontinuation of the SOR medication. However, its mechanism has not been clarified, and no effective prevention method has been reported for the symptoms. Therefore, this study aimed to analyze its mechanism and to develop an effective prevention regimen for the symptoms. Materials and methods: To assess the mechanism of SOR-induced HFS, the peripheral blood flow in the hand and foot was carefully monitored by Doppler ultrasound, thermography, and laser speckle flowgraphy in the cases treated with SOR and its contribution was assessed. Then, the effect of dried-bonito broth (DBB, which was reported to improve peripheral blood flow, on the prevention of the symptom was

    The variability of the promoter region and the 3'UTR (exon-7) of the BLG gene, encoding the β-lactoglobulin, was investigated by sequencing in 263 lactating Sarda goats in order to assess its association with milk traits. Milk traits included: milk yield, fat, total protein and lactose content, pH, daily fat and protein yield (DFPY), freezing point, milk energy, somatic cell count, total microbial mesophilic count, rennet coagulation time (RCT), curd firming rate (k20) and curd firmness (a30). A total of 7 polymorphic sites were detected and the sequence analysed was given accession number KM817769. Only three SNPs (c.-381C>T, c.-323C>T and c.*420C>A) had minor allele frequency higher than 0.05. The effects of farm, stage of lactation and the interaction farm × stage of lactation significantly influenced all the milk traits (P T and c.*420C>A (P T (P < 0.001). The c.-381TT homozygous goats showed lower pH, RCT and k20 than c.-381CT (P < 0.05). In conclusion the polymorphism of the goat BLG gene did not affect the total protein content of the Sarda goat milk, and only weakly influenced RCT and k20. On the other hand, an interesting effect on milk yields and DFPY emerged in two SNPs. This information might be useful in dairy goat breeding programs.

    In several species, circadian changes in melatonin concentrations play a key role in the photoperiodic control of seasonality. In sheep, two silent mutations in the melatonin receptor 1A gene (MTNR1A) at positions 606 and 612 of the exon II are associated with seasonal reproduction. However, in some sheep breeds, no relationships have been found between MTNR1A polymorphisms and reproductive seasonality. This lack of relationship could be due to effects of breed, body condition, age, and/or environmental conditions. Thus, the present study was conducted with the Sarda sheep breed with the aim of documenting the effect of MTNR1A gene polymorphisms on reproductive resumption and to evaluate whether such this effect was modified by differences in body condition score (BCS) and age. Six hundred three- to six-year-old multiparous ewes with BCSs between 2.5 and 3.5 were selected. Genomic DNA was extracted and subjected to PCR to amplify the ovine exon II of the MTNR1A gene. The amplicons were subjected to digestion with the restriction enzymes RsaI and MnlI to detect the T606C and A612G polymorphisms, respectively. Ewes carrying the G/G, G/A, C/C, and C/T genotypes exhibited higher fertility rates (Preproductive resumption in the Sarda sheep breed. Moreover, the data also indicated that, over the limited ranges evaluated in this study, BCS and age had no significant influence on reproductive activity. Copyright © 2014 Elsevier B.V.

    The 5' flanking region and 3' UTR of the caprine LALBA gene were analysed by SSCP and sequencing. A total of nine SNPs were detected: three in the promoter region, two were synonymous coding SNPs at exon-1, and four SNPs were in exon-4, within the 3'UTR. The nucleotide changes located in the promoter region (c.-358T>C, c.-163G>A, c.-121T>G) were genotyped by SSCP in 263 Sarda goats to evaluate their possible effect on milk yield, composition and renneting properties. We observed an effect of the three SNPs on milk yield and lactose content. Genotypes TT and CT at c.-358T>C (P A (P C and c.-121T>G were part of transcription factors binding sites, potentially involved in modulating the LALBA gene expression. The LALBA genotype affected renneting properties (P < 0.001), as heterozygotes c.-358CT and c.-163GA were characterised by delayed rennet coagulation time and curd firming time and the lowest value of curd firmness. The present investigation increases the panel of SNPs and adds new information about the effects of the caprine LALBA gene polymorphism.

    The Taciba and Rio Bonito ('lower' Triunfo Mbr) formations are divided into six depositional sequences based on cores, gamma-ray and electrical logs from shallow drillings from northern Santa Catarina State, Brazil. Each sequence is formed by two systems tracts, a lower one, sandy (low stand) and an upper one, shaly (high stand). The Taciba Formation has three sequences, S{sub 0} to S{sub 2}; sequence S{sub 0} has a thick turbidite sandstone at the base (Rio Segredo Member) that pinches out towards the eastern margin and even disappears in the Mafra outcrop area. Sequence S{sub 1} varies from a thin fluvial-estuarine system to a thick turbidite sandstone of a channelled fan system; S{sub 1} upper shaly system tract is marine in well PP-11, and it is glacially influenced in well PP-10. Sequence S{sub 2} is a thick sandstone body of shallow marine origin, but restricted to one well (PP-11); its upper shaly tract is dominated by massive siltstones intercalated with thin, distal tempestites. The 'lower' Triunfo Member (or 'Taciba- Triunfo transition') begins with the arrival of deltaic clastics of sequence S{sub 3} lower tract, coarsening-up from medial- to proximal delta front sandstones. Sequence S{sub 4} is quite similar to S{sub 3}, both showing sandstone pro gradation from north to south, as opposed to the southwest-sourced transgressive diamictites. Sequence S{sub 5} consists of fluvial deposits at well PP-12, and two transgressive cycles from wells PP-11 to PP-9, each one of them composed of fluvial-estuarine to marine systems. Well PP-10 is an exception, where the lower cycle presents de glaciation to marine deposits. (author)

    Full Text Available O objetivo deste trabalho é investigar o papel das estruturas subjacentes associadas à evolução tectônica regional e o seu reflexo na geomorfologia, a partir de uma abordagem morfotectônica na bacia do rio Bonito, localizada no extremo norte do município de Petrópolis, Planalto Serrano do Estado do Rio de Janeiro. As estruturas identificadas na área correspondem a falhas e famílias de juntas, que estão relacionadas com as descontinuidades de caráter regional e diretamente associadas ao contexto geológico regional ao qual se inserem, exibindo condições significativamente marcadas pelos processos vinculados à ruptura continental e abertura do Oceano Atlântico, iniciados a partir do Jurássico Superior, especialmente pela reativação de descontinuidades preexistentes. O controle tectônico-estrutural se reflete na compartimentação morfotectônica a partir (ada integração dos dados estruturais, da análise dos lineamentos da rede de drenagem, que definem trends de lineamentos que correspondem a estruturas identificadas e medidas, (b do relevo, que apresenta escalonamentos e o desenvolvimento de vales suspensos, e (c da distribuição espacial da cobertura sedimentar que reproduz a complexidade de feições observadas tanto no contexto local quanto no regional. Dessa maneira, tendo como princípio que a tectônica influencia diretamente a evolução da paisagem, os dados obtidos mostram uma interferência direta das estruturas na compartimentação morfotectônica e na dinâmica e evolução da paisagem da área em estudo.

    Full Text Available This article focuses in the handicrafts Kinikinau. It aims to analyze the marketing of artifacts produced by this ethnic group, in Bonito, ecotouristic city of Mato Grosso do Sul, Brazil. The Kinikinau were considered “extinct” for over half a century. Nowadays, they seek official recognition. The Kinikinau crafts became an important tool to help in the quest for ethnic strengthening, hence the relevance of the object. The survey data was conducted through visits to centers marketing the city of Bonito and the village of São João, Indian Reserve Kadiwéu, in Porto Murtinho, as well as collecting photographic records of handicrafts exhibited for sale, semi -structured interviews with traders and artisans. Secondary sources that deal with the production and marketing of handicrafts of other ethnicities are supporting the analysis. The results describe how is the flow of the Kinikinau handicrafts market created by the ecotourism, revealing the limitations that affect this process.

    Full Text Available This study aimed to provide information about the population structure and somatic index of Hypostomus cf. ancistroides collected from the Bonito river, located in the Ivaí river basin. The length-weight relationship was isometric for both the sexes. The length structure analysis showed that the larger individuals (from 18.1cm to 27.0cm in length predominated, and the lowest abundances occurred at the size extremes (9.1-12cm and 27.1-30.0cm. The reproduction period occured between October and January for the females and between November and January for the males. The liver somatic index cannot be used as an indicator of the reproduction period in either of the sexes, due to no correlation between the liver somatic index and the gonad somatic index. The gonad weight exerted no influence on the monthly mean condition factor and the correlation between the condition factor and gonad somatic index was high. The condition factor could be an indicator of the reproduction period of this species.Este estudo teve o objetivo de fornecer informações sobre a estrutura populacional e os índices somáticos de Hipostomus cf. ancistroides coletados no rio Bonito localizado na bacia do rio Ivaí.

Dating of some intrusions reveals ages between 120 and 75 Ma. Chemical analyses of garnet recovered in alluvium from traditional diamond digging areas indicate peridotitic garnet windows in Três Ranchos and Coromandel. Six hundred and eighty (680 diamonds acquired or recovered during mineral exploration in the digging areas of Romaria, Estrela do Sul, Três Ranchos and Coromandel show unique characteristics, certain populations indicating young, proximal and primary sources (YPP. Analyses of 201 stones from Santo Antônio do Bonito, Santo Inácio and Douradinho rivers alluvium, Coromandel, present no evidence of transport, characterizing a proximal source. Within these river basins, exposures of the Late Cretaceous Capacete Formation basal conglomerate contain mainly small rounded and/or angular quartzite pebbles and of basic and ultrabasic rocks, as well as kimberlite minerals (garnet, ilmenite, spinel, sometimes diamond. A magnetotelluric profile between the Paraná and Sanfranciscana basins shows that the thick underlying lithosphere in the Coromandel region coincides with the peridotitic garnet window and with a diamond population displaying proximal source characteristics. Diamond-bearing kimberlite intrusions occur in different areas of Alto Paranaíba.

O menor calibre destes órgãos permite um melhor acompanhamento do processo. As observações foram feitas em laranjeira cv. Pêra infetada pelo isolado severo Capão Bonito do CTV. Cinco fases do processo de formação de caneluras puderam ser deduzidas pelas análises anatômicas. As primeiras alterações são representadas pelo aparecimento de células adensadas, hipertrofia e hiperplasia no parênquima e câmbio do floema e uma desorganização generalizada desta área. Segue-se uma atividade intensa do câmbio do floema adjacente e sua expansão em direção ao xilema. Esta invasão do xilema resulta na ruptura do anel do xilema pela massa celular do floema constituída de células recém formadas de parede celular delgada. Esta invasão do floema em direção ao xilema inicia um processo de degeneração dos vasos e parênquima do xilema. Finalmente há um colapso completo da região do xilema invadida, que é substituída pela massa do floema, resultando na canelura, notada ao se remover a casca.An ontogenetic study of the stem pitting was carried out, using as a model system the peduncle of flowers and fruits of sweet orange cv.

    Full Text Available The aim of the study was to determine the monthly price distribution of the offered fish species for sale within the scope of information received from the centers engaged in the sale of retail fish during 2012-2013 fishing season in Sinop, Turkey. The enterprises were grouped as I (the most, II (middle and III (the least according to the sales volume and fish species. Each group was represented by two different fish enterprise and so a total of six separate enterprises were determined by purpose sampling method. During the study, sale prices and fish species were obtained twice every month at the same time of day. It was determined that anchovy (Engraulis encrasicolus ponticus, horse mackerel (Trachurus trachurus, bluefish (Pomatomus saltatrix, atlantic bonito (Sarda sarda, twait shad (Alosa fallax nilotica, needlefish (Belone belone, mullet (Mugil cephalus, shi drum (Umbrina cirrosa, brown meagre (Sciana umbra, common two-banded seabream (Diplodus vulgaris, annular bream (Diplodus annularis, tub gurnard (Trigla lucerna, picarel (Maena smaris, turbot (Psetta maxima, red mullet (Mullus barbatus, whiting (Merlangus merlangus, scorpion fish (Scorpaena porcus, goby (Gobius niger were offered for sale in fish markets. While the prices of higher economic valued fish species like anchovy, bluefish, atlantic bonito and turbot prices were different between the enterprises, the prices of horse mackerel, red mullet and whiting species were not different. When considering the fish prices based on years, the prices of horse mackerel, bluefish, atlantic bonito, red mullet and haddock during 2012-2013 years were close to the average price of 2008-2012 years and the prices of anchovy and turbot during 2012-2013 years were higher than the average price of 2008-2012 years in Sinop.

  3. Massive consumption of gelatinous plankton by Mediterranean apex predators.

    Directory of Open Access Journals (Sweden)

    Luis Cardona

    Full Text Available Stable isotopes of carbon and nitrogen were used to test the hypothesis that stomach content analysis has systematically overlooked the consumption of gelatinous zooplankton by pelagic mesopredators and apex predators. The results strongly supported a major role of gelatinous plankton in the diet of bluefin tuna (Thunnus thynnus, little tunny (Euthynnus alletteratus, spearfish (Tetrapturus belone and swordfish (Xiphias gladius. Loggerhead sea turtles (Caretta caretta in the oceanic stage and ocean sunfish (Mola mola also primarily relied on gelatinous zooplankton. In contrast, stable isotope ratios ruled out any relevant consumption of gelatinous plankton by bluefish (Pomatomus saltatrix, blue shark (Prionace glauca, leerfish (Lichia amia, bonito (Sarda sarda, striped dolphin (Stenella caerueloalba and loggerhead sea turtles (Caretta caretta in the neritic stage, all of which primarily relied on fish and squid. Fin whales (Balaenoptera physalus were confirmed as crustacean consumers. The ratios of stable isotopes in albacore (Thunnus alalunga, amberjack (Seriola dumerili, blue butterfish (Stromaeus fiatola, bullet tuna (Auxis rochei, dolphinfish (Coryphaena hyppurus, horse mackerel (Trachurus trachurus, mackerel (Scomber scombrus and pompano (Trachinotus ovatus were consistent with mixed diets revealed by stomach content analysis, including nekton and crustaceans, but the consumption of gelatinous plankton could not be ruled out completely. In conclusion, the jellyvorous guild in the Mediterranean integrates two specialists (ocean sunfish and loggerhead sea turtles in the oceanic stage and several opportunists (bluefin tuna, little tunny, spearfish, swordfish and, perhaps, blue butterfish, most of them with shrinking populations due to overfishing.

    The Crandallite are predominant in the lateritic phosphates of Sapucaia, in the form of the solid solution Crandallite (Cn)- Goyazite (Gz)-Florencite (Fl). The Crandallite-Goyazite is predominant, where the maximum proportion of Florencite is Cn 60 Cz 34.8 Fl 5.2 - This proportion of Florencite is relatively high for laterites, and for this case having up to 1,374% weight of TR 2 O 3 in the total sample. The light rare elements are predominant over the heavy ores, and are illustrated in the distribution curve normalized for the chondrites. This curve is partially comparable with the curve for Apatite presents slight negative anomaly for the element Europium, and slight positive anomaly for The elements Thulium. The geochemical caracteristics for the rare earths in this group allow the prediction for the original rock for the laterites. (author) [pt

  6. From bonito to anchovy: a reconstruction of Turkey’s marine fisheries catches (1950-2010

    2013-06-01

    Full Text Available Turkey’s marine fisheries catches were estimated for the 1950-2010 time period using a reconstruction approach, which estimated all fisheries removals, including unreported landings, recreational landings and discards.  We added these estimates to the ‘official’ data, as reported in TURKSTAT, which are also available from the United Nation’s Food and Agriculture Organization (FAO.  The total reconstructed catch for the 1950-2010 time period (inclusive of the reported data is approximately 32 million t, or 74% more than the 18.4 million t of reported data. This added approximately 13.6 million t to the reported data, consisting of 6.9 million t of unreported landings, 2.6 million t of discards, 2.4 million t of recreational catches, and 1.7 million t of subsistence catches.  In 2010, total reported marine landings for Turkey were 445,680 t and the total reconstructed catch was 763,760 t, or 73% more than the reported data.   The main unreported taxon by tonnage was European anchovy (Engraulis encrasicolus due to its sheer high proportion of catch.  The major reasons for underreporting include a general distrust fishers have towards the taxing system combined with inefficient fisheries monitoring and surveillance capabilities.  Accounting for all fisheries components is crucial in understanding the development of fisheries resources, improving management, and reducing threats to the domestic food security of Turkey.

    Full Text Available Aflatoxin B1 (AFB1 is a toxin produced by some strains of Aspergillus growing in feedstuffs. Dairy animals fed with diet containing AFB1 excrete aflatoxin M1 (AFM1 into the milk. The carry over ratio (AFM1 excreted in milk/ AFB1 ingested has been found lower in sheep (Battacone et al., 2002a than in cattle (Veldman et al., 1992. Being AFM1 linked to milk proteins, its concentration in curd is higher than in milk. The AFM1 concentration in milk resulted not influenced by milk production level in cattle, therefore the total amount of AFM1 excreted in milk and, consequently, the carry-over ratio increased with milk yield (Munksgaard et al., 1987; Veldman et al., 1992...

    The Spot and Runway Departure Advisor (SARDA) is a research prototype of a decision support tool for ATC tower controllers to assist in manging and controlling traffic on the surface of an airport. SARDA employs a scheduler to generate an optimal runway schedule and gate push-back - spot release sequence and schedule that improves efficiency of surface operations. The advisories for ATC tower controllers are displayed on an Electronic Flight Strip (EFS) system. The human-in-the-loop simulation of the SARDA tool was conducted for east operations of Dallas-Ft. Worth International Airport (DFW) to evaluate performance of the SARDA tool and human factors, such as situational awareness and workload. The results indicates noticeable taxi delay reduction and fuel savings by using the SARDA tool. Reduction in controller workload were also observed throughout the scenario runs. The future plan includes modeling and simulation of the ramp operations of the Charlotte International Airport, and develop a decision support tool for the ramp controllers.

There have been attempts to address the resulting inefficiencies with both strategic and tactical tools for metering departure aircraft. This presentation gives an overview of Spot And Runway Departure Advisor with Collaborative Decision Making (SARDA-CDM): an integrated strategic and tactical system for improving surface operations by metering departure aircraft. SARDA-CDM is the augmentation of ground and local controller advisories through sharing of flight movement and related operations information between airport operators, flight operators and air traffic control at the airport. The goal is to enhance the efficiency of airport surface operations by exchanging information between air traffic control and airline operators, while minimizing adverse effects on stakeholders and passengers. The presentation motivates the need for departure metering, and provides a brief background on the previous work on SARDA. Then, the concept of operations for SARDA-CDM is described. Then the preliminary results from testing the concept in a real-time automated simulation environment are described. Results indicate benefits such as reduction in taxiing delay and fuel consumption. Further, the preliminary implementation of SARDA-CDM seems robust for two minutes delay in gate push-back times.

    Full Text Available O estudo procurou determinar a relação entre julgamentos de atratividade física, indicadores sociométricos e atributos comportamentais em pré-escolares. A atratividade das crianças foi avaliada por três adultas familiarizadas com elas, por três adultas que não as conheciam, por seus colegas e por elas próprias. Foram apuradas as escolhas positivas e negativas que cada criança recebeu. As crianças julgaram o comportamento dos colegas dentro de quatro dimensões: alegre/ triste; agressivo/ não agressivo; sociável/ isolado; colaborador/ perturbador. Para avaliar a autopercepção das crianças, aplicou-se a Escala Ilustrada de Competência e Aceitação Social Percebidas para Crianças. Encontraram-se correlações significativas entre a avaliação de atratividade física segundo adultas familiarizadas e segundo os colegas com escolhas positivas e com atributos comportamentais pró-sociais. Os resultados denotam ligações entre afeto, julgamento de atratividade e avaliações comportamentais bem estabelecidas em crianças de 5 anos, indicando que o efeito do estereótipo torna-se menor à medida que aumenta o grau de informação sobre a pessoa que está sendo julgada.This study examined the correlation between preschool judgements of physical attractiveness, sociometric choices and behavioral descriptions of peers. Children's physical attractiveness was evaluated by three adults acquainted with the children, three not acquainted with the children, peers and by the children themselves. Peer's behavioral descriptions were related to: sadness/ happiness; aggression/ not aggression; sociability/ withdrawal; and cooperation/ disturbance. The Pictorial Scale of Perceived Competence and Social Acceptance was administered in order to evaluate children's self-perception. Significant correlations between adults acquainted with the children and peer's evaluations of physical attractiveness and sociometric choices and prosocial behavioral descriptions were found. Results suggest well established connections among affect, physical attractiveness judgements and behavioral descriptions in 5 years old, showing that the stereotype effect decreases as the degree of information about the judged target increases.

    Surface operations at airports in the US are based on tactical operations, where departure aircraft primarily queue up and wait at the departure runways. NASA's Spot And Runway Departure Advisor (SARDA) tool was developed to address these inefficiencies through Air Traffic Control Tower advisories. The SARDA system is being updated to include collaborative gate hold, either tactically or strategically. This paper presents the results of the human-in-the-loop evaluation of the tactical gate hold version of SARDA in a 360 degree simulated tower setting. The simulations were conducted for the east side of the Dallas/Fort Worth airport. The new system provides gate hold, ground controller and local controller advisories based on a single scheduler. Simulations were conducted with SARDA on and off, the off case reflecting current day operations with no gate hold. Scenarios based on medium (1.2x current levels) and heavy (1.5x current levels) traffic were explored. Data collected from the simulation was analyzed for runway usage, delay for departures and arrivals, and fuel consumption. Further, Traffic Management Initiatives were introduced for a subset of the aircraft. Results indicated that runway usage did not change with the use of SARDA, i.e., there was no loss in runway throughput as compared to baseline. Taxiing delay was significantly reduced with the use of advisory by 45% in medium scenarios and 60% in heavy. Arrival delay was unaffected by the use of advisory. Total fuel consumption was also reduced by 23% in medium traffic and 33% in heavy. TMI compliance appeared unaffected by the advisory

    Accumulation factors for Sr-90 and Cs-137 are given for a number of plants and fish taken from fresh-water bodies and from the Black Sea. The best indicators for following radioactive, Sr-90 contamination in fresh-water bodies are: Lemna minor and Subularia aquatica among the plants, while Tinca tinca L, Cyprinus carpio L and Cavassius carassius L are the most suitable among the fish for Sr-90. With respect to cesium-137 the most suitable as indicators are Sparganum affine and Subularia aquatica from the plants and Salmo trutta morpha fario L and Cyprinus carpio L. from the fishes. Among the saltwater hydrobionts as indicators of Sr-90 and Cs-137 water contamination the fish Sarda sarda L takes first place, and the plants Cystoseira barbata and Zostera marina take second place. 1 table, 6 refs.

    The geological results obtained in the Candiota Region by NUCLEBRAS, during the evaluation of the uranium economic potential from basal Gondwana Sequence - Itarare Group and Rio Bonito Formation - at South-East of the Parana Sedimentary Basin, are studied. The analysis of 18 geologic sections (scales 1:5.000 x 1:500), 21 drill holes and fotogeologic interpretation in the scale 1:50.000, are included. The Itarare Group sedimentation was conditioned by paleo - relief with valleys formed from differential erosion on 'horst - graben' structures. The deposition of its rhythmites, diamictites and siltstones was made in periglacial and marine environments. The sedimentation of the Rio Bonito Formation is related to the main Itarare Group depositional axes. The typical lithologies are: sandstones, siltstones, mudstones and coals, representing progradational fluvial sediments over coastal - plain areas. (Author) [pt

    Sedimentological analyses of about 80 drill cores from the Charqueadas - Santa Rita Coal Field, west of Porto Alegre, Rio Grande do Sul State, were made. The Itarare Group is characterized by pelites of lacustrine origin and conglomerates and sandstones of alluvial fans, mainly in the north western region. A shallow lacustrine and paludal system characterize the Rio Bonito Formation, comprising coal seams and associated pelitic sediments, as well as some paraconglomerates and sandstone layers. The contact between these units is established by the colour of the pelites, differences in sedimentary textures, structures and palynological data. A marine transgression caused the sediments of the Rio Bonito Formation to be covered by coastal sandstones and pelites of the Palermo Formation, of tidal flat origin. Today, the coal layers and sediments have been eroded southward and slope gently to the north of the area.

    The present study aimed to analyze the mycoflora and potential mycotoxin contamination of soil and corn samples collected at different plant maturity stages in Capão Bonito and Ribeirão Preto, two regions of the State of São Paulo, Brazil. In addition, the data obtained were correlated with the occurrence of wind-dispersed fungi and the predominant climatic conditions of the two regions studied. Corn mycoflora profiles showed that Fusarium verticillioides prevailed in 35% of the samples from Capão Bonito and in 49% of the samples from Ribeirão Preto. Examination of wind-dispersed fungi also revealed a high incidence of F. verticillioides. Soil mycoflora analyses showed that Penicilliumwas the most prevalent genus, although F. verticillioides was present in 55.5% of Capão Bonito's samples and in 26.7% of Ribeirão Preto's samples. With respect to water activity, the corn kernels most contaminated with F. verticillioides had water activity levels of 0.70-0.80. HPLC analysis of fumonisins revealed that 88.5% of Capão Bonito's kernels were contaminated with fumonisin B(1) (FB(1)) (0.09-10.87 microg/g) and 53.8% with fumonisin B(2) (FB(2)) (0.05-0.52 microg/g); Ribeirão Preto's kernels presented contamination levels of 93.5% for FB(1) (0.11-17.69 microg/g) and 61.3% for FB(2) (0.05-5.24 microg/g). No aflatoxins were detected by thin-layer chromatography in corn grains of either region. The concomitant occurrence of F. verticillioides and fumonisins in most of the field corn assayed demonstrates the importance of an effective control of cultivation throughout the plant maturity stages.

    Bonito municipality, known as an area of ecoturism, in Mato Grosso do Sul state, Brazil, is also a focus of visceral and cutaneous leishmaniases, with cases registered in both human and canine populations. This study sought to investigate natural infection by flagellate forms of Leishmania in phlebotomines of the urban area of Bonito. Sand flies were collected fortnightly from October 2005 to July 2006 with modified automatic light traps installed in peridomiciles and animal shelters in the center and on the outskirts of the city. The females were dissected and their guts observed under an optical microscope. A total of 1977 specimens were captured, Lutzomyia longipalpis (88.4 %) and Bichromomyia flaviscutelata (3.0 %) being the most frequent species. Bi. flaviscutellata was found infected by flagellates that were identified as Leishmania (Leishmania) amazonensis by indirect immunofluorescence reaction, employing monoclonal antibodies and the biotin-avidin system. This is the first report of natural infection by L. amazonensis in Bi. flaviscutellata in a Brazilian urban area. As Bi. flaviscutellata is only slightly attracted by humans, the transmission of L. amazonensis in the study area may have a zoonotic character; however, the sympatric occurrence of this parasite and Lu. longipalpis should be taken into consideration by the local health authorities since this sand fly has already been found with L. amazonensis DNA in a focus of canine visceral leishmaniasis in Bonito municipality.

    Incheon International Airport (ICN) is one of the hub airports in East Asia. Airport operations at ICN have been growing more than 5 percent per year in the past five years. According to the current airport expansion plan, a new passenger terminal will be added and the current cargo ramp will be expanded in 2018. This expansion project will bring 77 new stands without adding a new runway to the airport. Due to such continuous growth in airport operations and future expansion of the ramps, it will be highly likely that airport surface traffic will experience more congestion, and therefore, suffer from efficiency degradation. There is a growing awareness in aviation research community of need for strategic and tactical surface scheduling capabilities for efficient airport surface operations. Specific to ICN airport operations, a need for A-CDM (Airport - Collaborative Decision Making) or S-CDM (Surface - Collaborative Decision Making), and controller decision support tools for efficient air traffic management has arisen since several years ago. In the United States, there has been independent research efforts made by academia, industry, and government research organizations to enhance efficiency and predictability of surface operations at busy airports. Among these research activities, the Spot and Runway Departure Advisor (SARDA) developed and tested by National Aeronautics and Space Administration (NASA) is a decision support tool to provide tactical advisories to the controllers for efficient surface operations. The effectiveness of SARDA concept, was successfully verified through the human-in-the-loop (HITL) simulations for both spot release and runway operations advisories for ATC Tower controllers of Dallas-Fort Worth International Airport (DFW) in 2010 and 2012, and gate pushback advisories for the ramp controller of Charlotte-Douglas International Airport (CLT) in 2014. The SARDA concept for tactical surface scheduling is further enhanced and is being

    Full Text Available An individual variability in β-lactoglobulin content has been previously observed in Girgentana goat milk by HPLC analysis. To identify eventual mutations affecting the transcription level of the gene, the prooter region was characterized in goats showing an anomalous phenotype, consisting in a reduced content of β-lactoglobulin respect to α-lactoalbumine. A single nucleotide substitution not previously reported has been detected. A PCR-RFLP procedure was developed for fast detection of the mutation in different goat breeds: Girgentana, Garganica, Sarda, Alpine, Montefalcone and Saanen. The Montefalcone goat showed the highest frequency of the mutation, confirming one more the peculiarity of this breed.

  15. Taxi Time Prediction at Charlotte Airport Using Fast-Time Simulation and Machine Learning Techniques

    Science.gov (United States)

    Lee, Hanbong

    2016-01-01

    Accurate taxi time prediction is required for enabling efficient runway scheduling that can increase runway throughput and reduce taxi times and fuel consumptions on the airport surface. Currently NASA and American Airlines are jointly developing a decision-support tool called Spot and Runway Departure Advisor (SARDA) that assists airport ramp controllers to make gate pushback decisions and improve the overall efficiency of airport surface traffic. In this presentation, we propose to use Linear Optimized Sequencing (LINOS), a discrete-event fast-time simulation tool, to predict taxi times and provide the estimates to the runway scheduler in real-time airport operations. To assess its prediction accuracy, we also introduce a data-driven analytical method using machine learning techniques. These two taxi time prediction methods are evaluated with actual taxi time data obtained from the SARDA human-in-the-loop (HITL) simulation for Charlotte Douglas International Airport (CLT) using various performance measurement metrics. Based on the taxi time prediction results, we also discuss how the prediction accuracy can be affected by the operational complexity at this airport and how we can improve the fast time simulation model before implementing it with an airport scheduling algorithm in a real-time environment.

    In the southwestern United States (US), the Rio Grande chub (Gila pandora) is state-listed as a fish species of greatest conservation need and federally listed as sensitive due to habitat alterations and competition with non-native fishes. Characterizing genetic diversity, genetic population structure, and effective number of breeders will assist with conservation efforts by providing a baseline of genetic metrics. Genetic relatedness within and among G. pandora populations throughout New Mexico was characterized using 11 microsatellite loci among 15 populations in three drainage basins (Rio Grande, Pecos, Canadian). Observed heterozygosity (HO) ranged from 0.71–0.87 and was similar to expected heterozygosity (0.75–0.87). Rio Ojo Caliente (Rio Grande) had the highest allelic richness (AR = 15.09), while Upper Rio Bonito (Pecos) had the lowest allelic richness (AR = 6.75). Genetic differentiation existed among all populations with the lowest genetic variation occurring within the Pecos drainage. STRUCTURE analysis revealed seven genetic clusters. Populations of G. pandora within the upper Rio Grande drainage (Rio Ojo Caliente, Rio Vallecitos, Rio Pueblo de Taos) had high levels of admixture with Q-values ranging from 0.30–0.50. In contrast, populations within the Pecos drainage (Pecos River and Upper Rio Bonito) had low levels of admixture (Q = 0.94 and 0.87, respectively). Estimates of effective number of breeders (N b ) varied from 6.1 (Pecos: Upper Rio Bonito) to 109.7 (Rio Grande: Rio Peñasco) indicating that populations in the Pecos drainage are at risk of extirpation. In the event that management actions are deemed necessary to preserve or increase genetic diversity of G. pandora, consideration must be given as to which populations are selected for translocation.

  18. The flora of Early Permian coal measures from the Parana Basin in Brazil: A review

    Iannuzzi, Roberto

    2010-01-01

    This paper presents an updated overview integrating both previous and newly published data on the most important floras found associated with Early Permian coal seams in the Parana Basin, Brazil. These floras occur within the Rio Bonito Formation and correspond to the Gondwana ''Glossopteris Flora.'' For this review, five floras are selected, in ascending stratigraphic order: the ''Sao Joao do Triunfo,'' ''Figueira,'' ''Quiteria,'' ''Morro do Papaleo'' and ''Irapua Bed'' floras. They are the best-known floras of the basin in terms of taxonomic composition, paleoecology and environments of deposition. An early-mid Sakmarian to earliest Artinskian age is indicated for the Rio Bonito Formation based on absolute radiometric and relative biostratigraphic ages. Integration of available information about the selected floras allows evaluation of taphonomic and paleoecological factors to provide a more comprehensive understanding of the Early Permian floral record in the Parana Basin. The variation observed in both the taxonomic composition of individual floras and in the frequency of occurrence of different plant groups is due to the broad range of environmental/edaphic conditions that prevailed in the many different depositional settings represented in the Rio Bonito Formation. A more precise age determination obtained for the plant-bearing deposits permits the establishment of a more confident correlation between the Early Permian floral succession in the Parana Basin and other Early Permian floral successions in other basins. The Sakmarian global warming favored the appearance of pecopterid and sphenopterid ferns amongst the spore-producing plants, and the glossopterids amongst the pollen-producing plants. (author)

    The palynomorphs in the bore 313/1 of the Direccion Nacional de Mineria y Geologia are analyzed. Twenty three samples were processed, and only 9 were fertile. The lithologies correspond to sandstones of variable grain size, to mudstone and to diamictite, all of them assigned to the San Gregorio and Tres Islas Fms. The most abundant genera of sporare are essentially represented by monosaccate grains. Bisaccate and striated grains are very scare. The palynoflora is comparable with those studied in Brazil in the Fm Rio Bonito. Therefore, it is proposed that the sediments studied were deposited in the early Permian. (author)

    Full Text Available There are many researches showing interactions between olfaction and taste. Many of them supported that the interactions are not innate, but are learned through our daily eating experiences. Stevenson (2009 called this phenomenon as “learned synesthesia”. The authors also showed the interactions between flavor and taste are learned and processed by higher cognitive systems in rats and humans (Sakai et al., 2001; Sakai and Imada, 2003. Here the interactions between umami taste and dashi flavors are developed by the daily eating experience of Japanese traditional cuisine. Twenty flavors (such as sea weed, bonito, onion, garlic, ginger etc. by courtesy of YAMAHO CO. Ltd. were used as flavor stimuli. Taste stimuli are monosodium glutamate (umami substance, MSG, miso soup, and Katsuo Dashi (bonito soup stock. Participants tasted these stimuli, 12∼20 stimuli in a day, and evaluated the strength of umami taste, the palatability, congruity between taste and flavor with 100 mm visual analogue scales. The results of evaluations analyzed with the participants' daily eating experience showed the interactions between taste and flavor are developed by their own daily intake of traditional Japanese cuisine, especially dashi soup.

    Ribonucleotide flavor enhancers such as inosine monophosphate (IMP) and guanosine monophosphate (GMP) provide umami taste, similarly to glutamine. Japanese cuisine frequently uses soup stocks containing these nucleotides to enhance umami. We quantified 18 types of purines (nucleotides, nucleosides, and purine bases) in three soup stocks (chicken, consommé, and dried bonito soup). IMP was the most abundant purine in all umami soup stocks, followed by hypoxanthine, inosine, and GMP. The IMP content of dried bonito soup was the highest of the three soup stocks. We also evaluated the effects of these purines on extracellular and intracellular purine metabolism in HepG2 cells after adding each umami soup stock to the cells. An increase in inosine and hypoxanthine was evident 1 h and 4 h after soup stock addition, and a low amount of xanthine and guanosine was observed in the extracellular medium. The addition of chicken soup stock resulted in increased intracellular and extracellular levels of uric acid and guanosine. Purine metabolism may be affected by ingredients present in soups.

    Full Text Available A review of published papers and results of analysis of new material have allowed improvements on the palynostratigraphy of the Permian strata of the Paraná Basin in Rio Grande do Sul State. Based on first and last occurrences of certain species of pollen taxa, two palynozones are formalized, these are the Vittatina costabilis and Lueckisporites virkkiae Interval Zones, in ascending order. The Vittatina costabilis Interval Zone is subdivided into two units, in ascending order the Protohaploxypinus goraiensis and the Hamiapollenites karrooensis Subzones, and is recognized from the glacial (Itararé Group and post-glacial sequence (Rio Bonito Formation and the base of the Palermo Formation. The Lueckisporites virkkiae Interval Zone occurs from the uppermost Rio Bonito Formation, through the Palermo and Irati formations, and into the Serra Alta and Teresina formations. The main characteristics and reference sections are established, as well as additional criteria to recognize biostratigraphical units, in accordance with the International Stratigraphic Guide. Palynostratigraphical correlation suggests that the Vittatina costabilis Zone concerns the Early Permian (early Cisuralian, while the Lueckisporites virkkiae is regarded as late Early Permian to early Middle Permian (late Cisularian to early Guadalupian.

    In this study, total (T-Hg) and methyl mercury (Me-Hg) contamination was investigated in fishery products including canned fish, fish sauces, dried bonito and frozen tuna sashimi, collected from retail markets in Korea, to assess dietary exposure. Direct mercury analyser and gas chromatography-electron captured detector were employed to measure T-Hg and Me-Hg, respectively. The highest T-Hg and Me-Hg contamination was present in tuna sashimi, followed by dried bonito, respectively. Canned tuna showed more frequent detection and higher content than other canned fishery products. The weekly exposure estimate indicates that exposure to mercury from fishery products is safe, showing 2.59% provisional tolerable weekly intake (PTWI) for T-Hg, 1.82% PTWI for Me-Hg and 4.16% reference dose for Me-Hg. However, it should be addressed to monitor the mercury contamination in fish and fishery products regularly, to safeguard vulnerable population such as children, to limit intake of these food products.

    In Brazil economically important coal deposits occur in the southern part of the Parana Basin, where coal seams occur in the Permian Rio Bonito Formation, with major coal development in the states of Rio Grande de Sul and Santa Catarina. The current paper presents results on sequence stratigraphic interpretation of the coal-bearing strata, and petrological and geochemical coal seam characterization from the South Santa Catarina Coalfield, Parana Basin. In terms of sequence stratigraphic interpretation the precursor mires of the Santa Catarina coal seams formed in an estuarine-barrier shoreface depositional environment, with major peat accumulation in a high stand systems tract (Pre-Bonito and Bonito seams), a lowstand systems tract (Ponta Alta seam, seam A, seam B) and a transgressive systems tract (Irapua, Barro Branco and Treviso seams). Seam thicknesses range from 1.70 to 2.39 m, but high proportions of impure coal (coaly shale and shaley coal), carbonaceous shale and partings reduce the net coal thickness significantly. Coal lithoypes are variable, with banded coal predominant in the Barro Branco seam, and banded dull and dull coal predominantly in Bonito and Irapua seams, respectively. Results from petrographic analyses indicate a vitrinite reflectance range from 0.76 to 1.63 %Rrandom (HVB A to LVB coal). Maceral group distribution varies significantly, with the Barro Branco seam having the highest vitrinite content (mean 67.5 vol%), whereas the Irapua seam has the highest inertinite content (33.8 vol%). Liptinite mean values range from 7.8 vol% (Barro Branco seam) to 22.5 vol% (Irapua seam). Results from proximate analyses indicate for the three seams high ash yields (50.2 - 64.2 wt.%). Considering the International Classification of in-Seam Coals, all samples are in fact classified as carbonaceous rocks (> 50 wt.% ash). Sulfur contents range from 3.4 to 7.7 wt.%, of which the major part occurs as pyritic sulfur. Results of X-ray diffraction indicate the

    This paper describes the runway scheduler that was used in the 2014 SARDA human-in-the-loop simulations for CLT. The algorithm considers multiple runways and computes optimal runway times for departures and arrivals. In this paper, we plan to run additional simulation on the standalone MRS algorithm and compare the performance of the algorithm against a FCFS heuristic where aircraft avail of runway slots based on a priority given by their positions in the FCFS sequence. Several traffic scenarios corresponding to current day traffic level and demand profile will be generated. We also plan to examine the effect of increase in traffic level (1.2x and 1.5x) and observe trends in algorithm performance.

    In an attempt to standardise the determination of biological reference values, the International Federation of Clinical Chemistry (IFCC) has published a series of recommendations on developing reference intervals. The IFCC recommends the use of an a priori sampling of at least 120 healthy individuals. However, such a high number of samples and laboratory analysis is expensive, time-consuming and not always feasible, especially in veterinary medicine. In this paper, an alternative (a posteriori) method is described and is used to determine reference intervals for biochemical parameters of farm animals using an existing laboratory data set. The method used was based on the detection and removal of outliers to obtain a large sample of animals likely to be healthy from the existing data set. This allowed the estimation of reliable reference intervals for biochemical parameters in Sarda dairy sheep. This method may also be useful for the determination of reference intervals for different species, ages and gender.

    Goat milk and cheese production is continuously increasing and milk composition and coagulation properties (MCP) are useful tools to predict cheesemaking aptitude. The present study was planned to investigate the extension of lactodynamographic analysis up to 60 min in goat milk, to measure the farm and individual factors, and to investigate differences among 6 goat breeds. Daily milk yield (dMY) was recorded and milk samples collected from 1,272 goats reared in 35 farms. Goats were of 6 different breeds: Saanen and Camosciata delle Alpi for the Alpine type, and Murciano-Granadina, Maltese, Sarda, and Sarda Primitiva for the Mediterranean type. Milk composition (fat, protein, lactose, pH; somatic cell score; logarithmic bacterial count) and MCP [rennet coagulation time (RCT, min), curd-firming time (k 20 , min), curd firmness at 30, 45, and 60 min after rennet addition (a 30 , a 45 , and a 60 , mm)] were recorded, and daily fat and protein yield (dFPY g/d) was calculated as the sum of fat and protein concentration multiplied by the dMY. Data were analyzed using different statistical models to measure the effects of farm, parity, stage of lactation and breed; lastly, the direct and the indirect effect of breed were quantified by comparing the variance of breed from models with or without the inclusion of linear regression of fat, protein, lactose, pH, bacterial, somatic cell counts, and dMY. Orthogonal contrasts were performed to compare least squares means. Almost all traits exhibited high variability, with coefficients of variation between 32 (for RCT) and 63% (for a 30 ). The proportion of variance regarding dMY, dFPY, and milk composition due to the farm was moderate, whereas for MCP it was low, except for a 60 , at 69%. Parity affected both yield and quality traits of milk, with least squares means of dMY and dFPY showing an increase and RCT and curd firmness traits a decrease from the first to the last parity class. All milk quality traits, excluding fat, were

    Full Text Available The objective of this study was to develop a DNA test for rapid characterisation of goat κ-casein (κ-CN A and B variants and to study this polymorphism in Italian goat breeds. Genetic polymorphism of κ-CN gene was, in addition to isoelectric focusing, analysed according to a new technique designated as amplification created restriction site. Two alleles that differ in one nucleotide mutation (G Ø A in exon 4 were characterised. The 167-bp PCR product surrounding the nucleotide mutation was amplified from genomic DNA and the PCR product was digested with MaeIII. After digestion the A allele gives three fragments of 77, 65 and 25 bp in comparison with the B allele which gives two fragments of 90 and 77 bp. The analysis of allele frequency distribution at κ-CN locus, based on 401 individual samples, revealed significant differences among three goat breeds from the north of Italy (Nera di Verzasca, Frontalasca and Alpine with frequency of κ-CN B allele around 0.3, versus two goat breeds from the south of Italy (Maltese and Sarda with frequency of κ-CN B allele around 0.5. While two goat breeds (Maltese and Nera di Verzasca did not show significant deviations from the Hardy-Weinberg equilibrium, a highly significant excess of heterozygote genotype (AB was observed in Alpine, Frontalasca and Sarda goats. Here the developed DNA method and observed relatively high frequency of κ-CN B allele give a prerequisite for the assessment of research related to the simultaneous estimation of the effects of composite αs1/κ-CN genotypes on milk production and cheese-making properties.

    The trace elements Zr, Y, Sr, U, Rb, Th, Ga, Pb, Zn, Cu, Ni, Co, Cr, Ce, Ba and La were determined by X-Ray fluorescence spectroscopy on samples from shales, carbonaceous shales, coal and fine-grained groundmass of a paraconglomerate ( pedra-areia ) colleted from the Papaleo and Faxinal outcrops and from the Faxinal Coal Mine, Guaiba, RS. The analysis pointed out an association of zirconium, copper, uranium and thorium with coal and carbonaceous rocks, whereas barium and galium are related to inorganic rocks. The other elements showed neither preferential relationships with organic nor inorganic matter. The extremely high contents of uranium, cerium and lanthanum in the upper coal layers in both Papaleo and Faxinal outcrops suggest an association with the top of the Rio Bonito Formation in this area.

    Marcela de Castro Nunes Santos Terra

    Full Text Available ABSTRACT Galls are the result of a specific interaction between an inducer and a host plant. The species Heteropterys byrsonimifolia A. Juss. occurs in abundance in semideciduous seasonal forest ecotones and adjacent open formations. In the ecological reserve Quedas do Rio Bonito, located in the state of Minas Gerais, Brazil, this species is affected by a single gall morphotype. The present study aimed to evaluate whether the structural complexity of the host (test of the structural complexity hypothesis and the distance between hosts (test of the resource concentration hypothesis affect gall density in H. byrsonimifolia and to characterize the spatial distribution of the infestation. The results corroborate the two hypotheses tested, suggesting a metapopulation pattern of gall infestation in H. byrsonimifolia. Gallers were more successful in abrupt forest-savannah transition environments, which may be associated with greater stress-induced host vulnerability that plants usually experience in ecotones.

    Umami, the fifth basic taste, is the inimitable taste of Asian foods. Several traditional and locally prepared foods and condiments of Asia are rich in umami. In this part of world, umami is found in fermented animal-based products such as fermented and dried seafood, and plant-based products from beans and grains, dry and fresh mushrooms, and tea. In Southeast Asia, the most preferred seasonings containing umami are fish and seafood sauces, and also soybean sauces. In the East Asian region, soybean sauces are the main source of umami substance in the routine cooking. In Japan, the material used to obtain umami in dashi, the stock added to almost every Japanese soups and boiled dishes, is konbu or dried bonito. This review introduces foods and seasonings containing naturally high amount of umami substances of both animal and plant sources from different countries in Asia.

    We derive optimal a priori error estimates for discontinuous Galerkin (dG) time discrete schemes of any order applied to an advection-diffusion model defined on moving domains and written in the Arbitrary Lagrangian Eulerian (ALE) framework. Our estimates hold without any restrictions on the time steps for dG with exact integration or Reynolds\\' quadrature. They involve a mild restriction on the time steps for the practical Runge-Kutta-Radau methods of any order. The key ingredients are the stability results shown earlier in Bonito et al. (Time-discrete higher order ALE formulations: stability, 2013) along with a novel ALE projection. Numerical experiments illustrate and complement our theoretical results. © 2013 Springer-Verlag Berlin Heidelberg.

    Radiolytic formation of volatile compounds have been investigated in fillets of hake, codfish and bonito gamma-irradiated at a dose range of 0.1-5 Mrads. Analytical methods have been developed by gas chromatography of functional group derivatives: carbonyls as 2,4,-dinitrophenyl hydrazones, primary and secondary amines as N-alkyl benzamides, and thiols as 2,4-dinitrophenyl alkyl thioethers. The main results are as follows: increasing with the integral dose of the whole carbonyls, the most significant components being acetaldehyde, propional dehyde and formaldehyde; no significant variations with the integral dose od the traces of ammonia, methylamine, trimethylamine, ethylamine, diethylamine, propylamine, butylamine and pentylamine found in unirradiated samples; and radiolytic formation of methanethiol and dimethyl disulfide.

    Cotton blue disease is an aphid-transmitted cotton disease described in Brazil in 1962 as Vein Mosaic "var. Ribeirão Bonito". At present it causes economically important losses in cotton crops if control measures are not implemented. The observed symptoms and mode of transmission have prompted researchers to speculate that cotton blue disease could be attributed to a member of the family Luteoviridae, but there was no molecular evidence supporting this hypothesis. We have amplified part of the genome of a virus associated with this disease using degenerate primers for members of the family Luteoviridae. Sequence analysis of the entire capsid and a partial RdRp revealed a virus probably belonging to the genus Polerovirus. Based on our results we propose that cotton blue disease is associated with a virus with the putative name Cotton leafroll dwarf virus (CLRDV).

    Aspergillus repens strain MK82 produces an aspartic protease (PepA_MK82) that efficiently decolorises red-pigmented proteins during dried bonito fermentation. However, further expansion of the industrial applications of PepA_MK82 requires the high-level production and efficient preparation of the recombinant enzyme. The genomic DNA and cDNA fragments encoding the protease were cloned from strain MK82 and sequenced. Phylogenetic analysis of PepA_MK82 and comparisons with previously reported fungal aspartic proteases showed that PepA_MK 82 clusters with different groups of these enzymes. Heterologous expression of PepA_MK82 in Pichia pastoris yielded preparations of higher purity than obtained with an Escherichia coli expression system. Total protease activity in a 100-mL culture of the P. pastoris transformant was 14 times higher than that from an equivalent culture of A. repense MK82. The recombinant PepA_MK82 was easily obtained via acetone precipitation; the final recovery was 83%. PepA_MK82 and its recombinant had similar characteristics in terms of their optimal pH, thermostability, and decolorisation activity. The recombinant was also able to decolorise flaked, dried bonito and to bleach a blood-stained cloth. Given its ability to hydrolyse and decolorise red-pigmented proteins, recombinant PepA_MK8 can be exploited in the food industry and as a stain-removal agent in laundry applications. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    The late Paleozoic Ice Age (LPIA) is Earth's only record of a CO2-forced climatic transition from an icehouse to greenhouse state in a vegetated world. Despite a refined framework of Gondwanan ice distribution, questions remain about the timing, volume, and synchronicity of high-latitude continental ice and the subsequent deglaciation. These questions ultimately preclude our understanding of linkages between ice volume, sea level, and high- and low-latitude climate. Poor constraints on the timing and synchronicity of glacial and interglacial transitions reflect a lack of high-resolution radioisotopic dates from high-latitude, ice-proximal Carboniferous-Permian successions. The Rio Bonito Fm in Rio Grande do Sul State of southern Brazil hosts the oldest non-glaciogenic Carboniferous- Permian deposits of the Paraná Basin, thus recording the icehouse-to-greenhouse transition. Despite a widespread effort over the last two decades to constrain these deposits in time by means of U-Pb zircon geochronology, published data sets of the Candiota and Faxinal coals of the Rio Bonito Fm host discrepancies that may reflect post- eruptive open system behavior of zircon and analytical artifacts. These discrepancies have hindered the correlation of the Candiota and Faxinal sediments within the larger Gondwanan framework. Here we present the first U-Pb ages on closed system single zircons using CA-TIMS techniques on Permo-Carboniferous ash deposits of the Paraná Basin. Preliminary results indicate two major and distinct coal-forming periods that are separated by ca 10 Ma. Our results and conclusions are not in agreement with multi- crystal U-Pb TIMS and SIMS ages that suggest coeval deposition of the Candiota and Faxinal coals. CA-TIMS analyses applied to zircons from additional ash deposits are aimed at constructing a robust chronostratigraphic framework for the Carboniferous- Permian succession of the Paraná Basin, which will facilitate a better understanding of the timing and

    Full Text Available ABSTRACT: Objective: Anserine, which is abundant in avian species and in a wide range of fish such as bonito and tuna, is reported to have anti-fatigue effect. Although chicken soup and bonito soup is traditionally used to recover from physical fatigue, it is generally difficult to verify the effect in humans. This study was to directly demonstrate the anti-fatigue effect of oceanic anserine in humans. Methods: Edible-grade anserine was purified from fish extract with food-grade reagents. Subjects were 17 healthy male volunteers (35.5 ± 5 yr., 75.5 ± 5.0 kg. Each subject performed the isometric exercise tolerance test (ETT on the rectus femoris muscle twice (Ex_1, Ex_2 both for anserine and water conditions on a different day. Median frequency changes (MDF during Functional Foods in Health and Disease 2013; 3(10 389-399 ETTs were calculated and regression curves were calculated over a frequency range of 21-214 Hz. The difference, or angle, between the slopes of Ex_1 and Ex_2 MDF regression curves, which corresponds to the degree of fatigue, was defined as an angle fatigue index and compared between anserine and water intake conditions. Results: MDF decreased during ETTs in most patients and the slopes of regression curves were larger in Ex_2 than in Ex_1. Angle fatigue index for water (control was significantly larger than that for anserine (p<0.01, paired t-test, n=17. The result indicates that anserine have an anti-fatigue effect on skeletal muscle in humans. Conclusions: We proposed the angle fatigue index as a touchstone of the muscle fatigue. The index indicates that anserine is effective to reduce the muscle fatigue in humans.

    To determine the prophylactic effects of an elastin peptide derived from the bulbus arteriosus of bonitos and prolylglycine (PG), a degradation product of elastin peptide, on vascular dysfunction in spontaneously hypertensive rats (SHRs). Male 15-week-old SHR/Izm rats were fed without (control group) or with elastin peptide (1 g/kg body weight) for 5 weeks (EP group), or were infused via an osmotic mini-pump for 4 weeks with PG (PG group) or saline (control group). Using thoracic aortas, we assessed endothelial changes by scanning electron microscopy. Vascular reactivity (contraction and relaxation) and pressure-induced distension was compared. mRNA production levels of endothelial nitric oxide synthase (eNOS) and intercellular adhesion molecule-1 (ICAM-1) were investigated by real-time-polymerase chain reaction. Aortas of the EP group displayed limited endothelial damage compared with that in the control group. Under treatment of SHRs with elastin peptide, the effect of phenylephrine returned closer to the normal level observed in normotensive Wistar-Kyoto (WKY/Izm) rats. mRNA production of eNOS (but not ICAM-1) was greater in the EP group than in the control group. Endothelial damage was suppressed and pressure-induced vascular distension was greater in the PG group than in the corresponding control group. These results suggest that elastin peptide from bonitos elicits prophylactic affects hypertension-associated vascular dysfunction by targeting the eNOS signaling pathway. PG may be a key mediator of the beneficial effects of elastin peptide. Copyright © 2014 Elsevier Inc. All rights reserved.

Aumentar o número de variedades, assim como ampliar o período de safra são fatores importantes tendo em vista que trarão vantagens ao consumidor e ao produtor desse grupo de citros. No período de 2002 a 2005, foram estudadas as características da variedade Fremont e comparadas com as tangerinas 'Ponkan' e 'Clementina Nules', no município de Capão Bonito-SP. Pode-se concluir, dos resultados obtidos, que as plantas da tangerina Fremont são de porte reduzido (semi-anãs; os frutos apresentam características excepcionais para consumo in natura, maturação de meia-estação e período de colheita, que se estende por até três meses, sendo dessa maneira boa opção para plantios visando à entressafra da 'Ponkan'.Commercial grown tangerines variety are mainly restricted to a few options such as Ponkan tangerine and Murcott tangor. The increasing number of varieties as well as the harvest extending season is important, potentially benefiting consumers and producers of this kind of citrus. Fremont characteristics were compared to Ponkan and Clementina Nules tangerines at Capão Bonito County in São Paulo State from 2002 to 2005. By the results, it was possible to conclude that Fremont trees were semi-dwarfed, the fruits had excellent characteristics for in natura consumption and a harvesting season enlargement of three months, therefore appearing to be a good alternative for orchards, aiming at Ponkan' off-season period.

  14. "Treatises on Earthquakes" in late Renaissance (16th-17th cent), at the roots of historical seismology

    Albini, P.

    2009-04-01

    It was soon after the damaging November 1570 earthquake at Ferrara, Northern Italy, that the academic Stefano Breventano from Pavia, a small town in Northern Italy as well, started to compose his "Treatise on the earthquake". Completed by September 1576, this 250-page manuscript was to remain unpublished for centuries. The critical edition recently appeared (Albini, 2007) was a due tribute to the remarkable amount of information put together by Breventano, an otherwise "obscure" literate who, before getting involved with earthquakes, had published a history of the antiquities and remarkable events at his hometown Pavia (1570). Indeed, he was not the first Renaissance author to pursue the goal of checking into the historical sources of the previous centuries in search of earthquakes and other natural phenomena. What is outstanding in his "Treatise" is that he suceeded in retrieving information on more than two hundred earthquakes, along two thousand years, between 504 B.C. and 1575 A.D., covering the whole Euro-Mediterranean region, and the West Indies in early 16th century. Breventano's essay is here presented, together with a comparison between his style and amount of information with those included in the work by the contemporary British author Stephen Batman, "The Doome warning all men to the Judgement" (1581). A later treatise is presented also, the work by Marcello Bonito (1690) "Terra Tremante [Trembling Earth]", which could easily be defined as a worldwide list of earthquakes. In structure and content, Bonito's work goes along the same lines of Breventano, and could be considered a precursor of today descriptive catalogues, because of his outstandingly modern approach that paved the way to modern historical seismology.

    This paper proposes a new departure pushback decision-support tool (DST) for airport ramp-tower controllers. It is based on NASA's Spot and Runway Departure Advisor (SARDA) collaborative decision-making concept, except with the modification that the gate releases now are controlled by tactical pushback (or gate-hold) advisories instead of strategic pre-assignments of target pushback times to individual departure flights. The proposed ramp DST relies on data exchange with the airport traffic control tower (ATCT) to coordinate pushbacks with the ATCT's flow-management intentions under current operational constraints, such as Traffic Management Initiative constraints. Airlines would benefit in reduced taxi delay and fuel burn. The concept was evaluated in a human-in-the-loop simulation experiment with current ramp-tower controllers at the Charlotte Douglas International Airport as participants. The results showed that the tool helped reduce taxi time by one minute per flight and overall departure flight fuel consumption by 10-12% without reducing runway throughput. Expect Departure Clearance Time (EDCT) conformance also was improved when advisories were provided. These benefits were attained without increasing the ramp-tower controllers' workload. Additionally, the advisories reduced the ATCT controllers' workload.

    The German Aerospace Center (DLR) and the National Aeronautics and Space Administration (NASA) have been independently developing and testing their own concepts and tools for airport surface traffic management. Although these concepts and tools have been tested individually for European and US airports, they have never been compared or analyzed side-by-side. This paper presents the collaborative research devoted to the evaluation and analysis of two different surface management concepts. Hamburg Airport was used as a common test bed airport for the study. First, two independent simulations using the same traffic scenario were conducted; one by the DLR team using the Controller Assistance for Departure Optimization (CADEO) and the Taxi Routing for Aircraft: Creation and Controlling (TRACC) in a real-time simulation environment, and one by the NASA team based on the Spot and Runway Departure Advisor (SARDA) in a fast-time simulation environment. A set of common performance metrics was defined. The simulation results showed that both approaches produced operational benefits in efficiency, such as reducing taxi times, while maintaining runway throughput. Both approaches generated the gate pushback schedule to meet the runway schedule, such that the runway utilization was maximized. The conflict-free taxi guidance by TRACC helped avoid taxi conflicts and reduced taxiing stops, but the taxi benefit needed be assessed together with runway throughput to analyze the overall performance objective.

    Soybean lecithin may represent a suitable alternative to egg yolk for semen cryopreservation in livestock species. However, additional studies are needed to elucidate its effects on spermatozoa functional properties. Semen collected from five Sarda bucks was cryopreserved in Tris-based extender and glycerol (4% v:v) with different supplementations. In a preliminary experiment, different soybean lecithin concentrations were tested (1%-6% wt/vol) and results in terms of viability, percentages of progressive motile and rapid spermatozoa, and DNA integrity after thawing showed that the most effective concentration was 1%. In the second experiment, semen was frozen in a Tris-based extender with no supplementation (EXT), with 1% lecithin (EXT LC), and 20% egg yolk (EXT EY). The effectiveness of these extenders was also compared with a commercial extender. The EXT EY led to the highest viability and motility parameters after freezing and thawing (P lecithin can be considered as a suitable alternative to egg yolk in goat semen cryopreservation, because it ensures higher fertilization rates and a better protection from membrane damage by cold shock.

Attualmente il modello riferito alla cultura sarda della Prima età del Ferro e delle età successive è quello degli Entangled Objects and Hybrid Practices.   Abstract: The possible development of the culture of the indigenous communities of Sardinia, from the early Iron Age to the acquisition of the urban settlement in the Punic period, leads us to a reflection on the applying models to the different Phoenician and Carthaginian urban archaeological contexts and the areas directly related to the Carthaginian colonization, although it could be possible to find cultural Sardinian elements. Currently the model refers to the Sardinian culture of the First Iron Age and later ages is that of Entangled Objects and Hybrid Practices.

It is located very close to the site of S'Adde 'e S'Ulumu, where an important hoard of bronze objects was found, once considered to belong to a single individual for the absence of any clear archaeological context. This hoard acquires a new dimension thanks to the new data presented here: it could have reasonably been part of a set of ritual activities carried out in a sacred area formed of buildings and spaces between them, a common pattern in Sardinian communities during the Early Iron phase. This poster was presented at the Workshop Materiali e contesti dell'Età del Ferro sarda (Materials and contexts in the Sardinian Iron Age, organised by the University of Glasgow and the Comune di San Vero Milis on the 25th of May 2012, and supported for by the Royal Society of Edinburgh, the Comune di San Vero Milis, the University of Glasgow and the Carnegie Trust of the Universities of Scotland.

    Growth hormone (GH) is encoded by the GH gene, which may be single copy or duplicate in sheep. The two copies of the sheep GH gene (GH1/GH2-N and GH2-Z) were entirely sequenced in one 106 ewes of Sarda breed, in order to highlight sequence polymorphisms and investigate possible association between genetic variants and milk traits. Milk traits included milk yield, fat, protein, casein and lactose percentage. We evidenced 75 nucleotide changes. Transcription factor binding site prediction revealed two sequences potentially recognised by the pituitary-specific transcription factor POU1FI at the GH1/GH2-N gene, which were lost at the promoter of GH2-Z, which might explain the different tissues of expression of GH1/GH2-N (pituitary) and GH2-Z (placenta). Significant differences in milk traits were observed among genotypes at polymorphic loci only for the GH2-Z gene. Sheep with homozygote genotype ss748770547 CC had higher fat percentage (P < 0.01) than TT. SNP ss748770547 was part of a potential transcription factor binding site for C/EBP alpha (CCAAT/Enhancer Binding Protein), which is involved in the regulation of adipogenesis and adipoblast differentiation. SNP ss748770547, located in the GH2-Z gene 5' flanking region, may be a causal mutation affecting milk fat content. These findings might contribute to the knowledge of the sheep GH locus and might be useful in selection processes in sheep.

    This study focuses on the uses of the electrical tomography and its relationship with hydrochemical data in order to characterize contaminated groundwater flows in fractured aquifers. The studied area is contaminated with different hazardous substances like lyndanes, organochlorinated compounds and benzenes coming from the old non-controlled Sardas landfill. The enormous volumes of wastes filling the landfill have generated a convoluted mixture of leachates. Due to the lack of a landfill liner, the leachates have migrated through the fractured Eocene marls towards the Gallego River. The striking correlation between high concentrations of polluted groundwater and low electrical resistivity of the subsurface (< 8 Ω·m) allows defining the principal contaminant migration route thanks to the distribution of these conductive anomalies. This mapping verifies that there is intense tectonical–structural control of the leachate migration, because the deep migration presents the same direction as the geological axis fold. - Highlights: • The outcrop topographic reconstruction is done using cores and aerial photographs. • Hydrochemical and geophysical data allow defining two leachate migration paths. • Conductive anomalies in ERT are linked to high contaminant concentration. • The distribution of conductive anomalies defines the fractured basement migration. • The plume direction reflects important tectonic control in the migration process.

    The Sulcis coalfield was discovered in 1851. For several years it was mined at very low rate until 1936 when the Italian government decided to intensify its exploitation, founding the 'Carbonifera Sarda' company. Resumption of work led to the construction of new coal washeries, the renovation of old power stations and the creation of new ones. Some attempts were made to convert coal through the application of gasification technology, at San Gavino foundry and in a small plant near the town of S. Antioco. Thus the town of Carbonia was founded and was opened in December 1938. As a result of growing social and economic needs in the area, Carbonia s Municipal Administration has always been committed to utilizing the local reserves of coal. For example, the town was actively involved in the IGCC Sulcis project and, at present, it is working on a very important town planning initiative which involves the restoration of the old Serbariu mine buildings on the outskirts of the town. The Municipal Administration will renovate the 'Lampisteria' building turning it into a mining museum as well as restoring the old warehouse (thanks to an agreement with Sotacarbo) and making it a Research Centre for advanced coal technologies development. This Research Centre will be a national centre for developing clean coal technologies and for promoting coal utilization. 14 refs., 12 figs.

Os impactos ambientais negativos, provocados em qualquer porção da bacia podem interferir na quantidade e qualidade da água e, dependendo do impacto, formas ou alternativas diferentes de manejo deverão ser implantadas visando à melhoria do ambiente. Este trabalho teve por objetivo a caracterização das nascentes da bacia do córrego Itanguá, Capão Bonito, SP, Brasil, quanto ao tipo e estado de conservação, assim como a identificação de impactos ambientais negativos presentes. Quanto ao tipo, as nascentes foram classificadas em pontual ou difusa, e o estado de conservação obtido por meio da avaliação macroscópica foi ranqueado em ótimo, bom, razoável, ruim e péssimo. Na bacia foram identificadas 19 nascentes e, das 15 que foram visitadas, nove foram classificadas como pontuais, enquanto que seis foram difusas. Quanto ao estado de conservação, duas foram classificadas como ótimas, 12 como boas e uma como razoável. Também a partir da avaliação macroscópica foi observado que a presença de espécies exóticas, tanto animal (Sus scrofa como vegetal (Pinus spp., e a ausência de vegetação nativa na área de preservação permanente foram os impactos ambientais negativos mais frequentes. A metodologia empregada se mostrou eficiente como análise qualitativa visual da situação das nascentes e como fornecedoras de informação para subsidiar ações para a conservação da água na Floresta Nacional de Capão Bonito, SP, Brasil.

    Nogal Peak quadrangle is located in the northern Sierra Blanca Igneous Complex (SBIC) and contains most of the White Mountain Wilderness (geologic map is available at http://geoinfo.nmt.edu/publications/maps/geologic/ofgm/details.cfml?Volume=134). The geology of the quad consists of a late Eocene to Oligocene volcanic pile (Sierra Blanca Volcanics, mostly alkali basalt to trachyte) intruded by a multitude of dikes, plugs and three stocks: Rialto, 31.4 Ma (mostly syenite), Three Rivers, ca. 29 to 27 Ma (quartz syenite intruded by subordinate alkali granite), and Bonito Lake, 26.6 Ma (mostly monzonite). Three Rivers stock is partially surrounded by alkali rhyolites that geochemically resemble the alkali granites. The circular shape of the stock and surrounding rhyolites suggests they form the root of a probable caldera. SBIC rocks have compositions typical of those found within the Rocky Mountain alkaline belt and those associated with continental rift zone magmatism. Because the volcanic host rocks are deeply eroded, intrusive relations with the stocks are well exposed. Most contacts at stock margins are near vertical. Roof pendants are common near some contacts and stoped blocks up to 700 m long are found within the Three Rivers stock. Contacts, pendants and stoped blocks generally display some combination of hornfelsing, brecciation, fracturing, faulting and mineralization. Sierra Blanca Volcanics display hydrothermal alteration increasing from argillic in the NW sector of the quad to high-temperature porpylitic near stock margins. Retrograde phyllic alteration occurs within breccia pipes and portions of the stocks. Mineral deposits consist of four types: Placer Au, fissure veins (mostly Ag-Pb-Zn±Au), breccia pipes (Au-Mo-Cu), and porphyry Mo-Cu. A singular pipe on the SW margin of Bonito Lake stock contains sapphire-lazulite-alunite. Although Au has been intermittently mined in the quad since 1865, best production of Au originated around the turn of the last

    Hanabanilla and Paso Bonito Reservoirs are the main fresh water sources for about half a million inhabitants in central Cuba. Prior to this investigation precise information about the losses of storage capacity was not available. Sedimentation is the dominant process leading to reduction in water storage capacity. We investigated the sedimentation process in both reservoirs by analyzing environmental radionuclides (e.g. 210 Pb, 226 Ra and 137 Cs) in sediment cores. In the shallow Paso Bonito Reservoir (mean depth of 6.5 m; water volume of 8 × 10 6  m 3 ), we estimated a mean mass accumulation rate (MAR) of 0.4 ± 0.1 g cm -2 y -1 based on 210 Pb chronologies. 137 Cs was detected in the sediments, but due to the recent construction of this reservoir (1975), it was not possible to use it to validate the 210 Pb chronologies. The estimated MAR in this reservoir is higher than the typical values reported in similar shallow fresh water reservoirs worldwide. Our results highlight a significant loss of water storage capacity during the past 30 years. In the deeper and larger Hanabanilla Reservoir (mean depth of 15.5 m; water volume of 292 × 10 6  m 3 ), the MAR was investigated in three different sites of the reservoir. The mean MARs based on the 210 Pb chronologies varied between 0.15 and 0.24 g cm -2 y -1 . The MARs calculated based on the 137 Cs profiles further validated these values. We show that the sediment accumulation did not change significantly over the last 50 years. A simple empirical mixing and sedimentation model that assumes 137 Cs in the water originated from both, direct atmospheric fallout and the catchment area, was applied to interpret the 137 Cs depth profiles. The model consistently reproduced the measured 137 Cs profiles in the three cores (R 2  > 0.9). Mean residence times for 137 Cs in the water and in the catchment area of 1 y and 35-50 y, respectively were estimated. The model identified areas where the catchment component

    2016-02-01

    Histamine fish poisoning, also known as scombroid poisoning, is the most common cause of ichythyotoxicosis worldwide and results from the ingestion of histamine-contaminated fish in the Scombroidae and Scomberesocidae families, including mackerel, bonito, albacore, and skipjack. This disease was first described in 1799 in Britain and re-emerged in the medical literature in the 1950s when outbreaks were reported in Japan. The symptoms associated with histamine fish poisoning are similar to that of an allergic reaction. In fact, such histamine-induced reactions are often misdiagnosed as IgE-mediated fish allergy. Indeed, histamine fish poisoning is still an underrecognized disease. In this review, we discuss the epidemiology, pathophysiology, evaluation, and treatment of scombroid disease. Because more than 80% of fish consumed in the USA is now imported from other countries, the disease is intimately linked with the global fish trade (National Marine Fisheries Service, 2012). Preventing future scombroid outbreaks will require that fishermen, public health officials, restaurant workers, and medical professionals work together to devise international safety standards and increase awareness of the disease. The implications of scombroid poisoning go far beyond that of fish and have broader implications for the important issues of food safety.

  19. Genetic evidence of population structuring in the neotropical freshwater fish Brycon hilarii (Valenciennes, 1850

    Full Text Available Brycon hilarii is a migratory fish widely distributed throughout the Paraguay River Basin. It is appreciated in sport fishing and for its superior meat quality. It is also the main species for tourist attraction in the Bonito region (State of Mato Grosso do Sul, Brazil. Considering the lack of information on the genetic structure of the fish of this species, the aim of the present study was to detect the genetic variability of Brycon hilarii through RAPD markers. A total of eighty specimens collected in different seasons at four sites of the Miranda River sub-basin (Paraguay River Basin, Brazil were used for analysis. The results of genetic similarity, Shannon diversity, and AMOVA revealed differences between the sampling sites. Through AMOVA, differences between populations were more evident among the animals collected during the non-reproductive season, corresponding to a time of less movement of these fish. A population structuring model in which B. hilarii appears organized into genetically differentiated reproductive units that coexist and co-migrate through the studied system was suggested, contrasting the currently accepted idea that freshwater migratory fish form large panmictic populations in a determined hydrographic system. Despite the lack of a complete picture regarding the distribution of B. hilarii in the studied region, this initial idea on its population genetic structure could be an important contribution to providing aid for management and conservation programs of these fish.

    Sound recordings were made at a natural outdoor amphitheater in Chaco Canyon and in a reconstructed great kiva at Aztec Ruins. Recordings included computer-generated tones and swept sine waves, classical concert flute, Native American flute, conch shell trumpet, and prerecorded music. Recording equipment included analog tape deck, digital minidisk recorder, and direct digital recording to a laptop computer disk. Microphones and geophones were used as transducers. The natural amphitheater lies between the ruins of Pueblo Bonito and Chetro Ketl. It is a semicircular arc in a sandstone cliff measuring 500 ft. wide and 75 ft. high. The radius of the arc was verified with aerial photography, and an acoustic ray trace was generated using cad software. The arc is in an overhanging cliff face and brings distant sounds to a line focus. Along this line, there are unusual acoustic effects at conjugate foci. Time history analysis of recordings from both sites showed that a 60-dB reverb decay lasted from 1.8 to 2.0 s, nearly ideal for public performances of music. Echoes from the amphitheater were perceived to be upshifted in pitch, but this was not seen in FFT analysis. Geophones placed on the floor of the great kiva showed a resonance at 95 Hz.

    For the purpose of effectively using marine products in Kochi pref., analyses were made of the components of the following marine products: the head and inside of frigate mackerel disposed of at the time of producing dried frigate mackerel (an annual catch of the frigate mackerel is about 12000-15000 tons, almost half of which is used for processing for dried bonito), the head and other part of lobster disposed of at lobster restaurants (including the shell of lobster), the skin of lazard fish disposed of in boiled fish paste producing plants. The analysis was conducted in terms of the composition of coarse fatty and fatty acid, free amino acid, ATP related compounds, etc. As a result, the following were found out: in the fat of the head and inside of frigate mackerel, DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) were included by 20-30% and 10%, respectively, and the fat is promising as supply source of high-grade unsaturated fatty acid; in the head and other part of lobster, chitin chitosan is included in addition to free amino acid such as glycine and alanine; in the skin of lazard fish, ATP related compounds such as inosinic acid are included, and the skin is useful for a raw material of the seasoning. 15 refs., 4 figs., 6 tabs.

    Full Text Available Erythrina speciosa is specie suitable for forest recuperation programm. As its seeds coats are impermeable to water absorption, the aim of this work was to study the change of biometric characters during seed germination and analyse the physiological quality of E. speciosa seeds from different sources. Therefore, seeds were collected from Capão Bonito and Ribeirão Grande, two municipilties of São Paulo State, Brazil, and were scarified. For each replicate were used 15 seeds. The germination test was conducted at 25 °C with photoperiod of 12 hours, using vermiculite packed in seedling boxes. We evaluated the germination percentage, germination speed index, seedling stem diameter and number of leaves. The results showed that the seeds of different sources showed wide variability in biometric characteristics, external dimensions and fresh weight, but such data did not correlate with seed germination and growth of seedlings in the nursery, so it is not necessary separate the seeds for seedling production process.

    During the fall of 1987, Complete Archaeological Service Associates conducted mitigative excavations at three sites (LA50363, LA50364, and LA50371) in McKinley County, New Mexico. These sites are adjacent to the Phillips/United Nuclear Inactive Uranium Mill and Tailings site at Ambrosia Lake, New Mexico. The primary deposition at each of these sites appears to be related to a Pueblo II or Bonito Phase occupation. Temporal placement is based primarily on the cross dating of ceramics and archaeomagnetic determinations when possible. No tree-ring or radiocarbon samples are available from these sites. These Ambrosia Lake sites indicate that this area was occupied primarily by Pueblo II people who may have had close social, economic, and ceremonial ties with the people living at the nuclear community of Lower Nizhoni about 3 km south-southeast. The later component at LA50364 indicates a Pueblo III occupation by people who may have had similar ties to the people of the Kin Nizhoni nuclear community. The Ambrosia Lake sites, then, provide important information on the structure of subnuclear communities within the southern Chaco periphery

    Water soluble polymers have been used extensively in the petroleum recovery, due to their ability in increasing the viscosity of the injection water and to reduce water/oil mobility ratio and the water relative permeability in the reservoir. This reduction acts favorably as a secondary effect, and it reestablishes part of the pressure in the reservoir after the flow of the polymer, causing a correction of the injection profile in the wells through the restructuring of the resident fluids in the porous media. Nevertheless, some parameters influence the improve of this mechanism, such as petrophysics properties, chemical composition of the rock, adsorption, resistance factor and the residual resistance factor. Many paper in the area of polymers applied to the enhanced petroleum recovery indicate a high efficiency in the injection of different partially hydrolysed polyacrylamides, in different concentrations, or even in different injection conditions, as: temperature, flow, among others. In this work it was evaluated the behavior and efficiency of partially hydrolysed polyacrylamide flooding on outcrop cores from Botucatu, Rio Bonito, Clashach and Assu, using core flow tests and computer simulations.

    2005-01-01

    Previous analysis of 87Sr/86Sr ratios shows that 10th through 12th century Chaco Canyon was provisioned with plant materials that came from more than 75 km away. This includes (1) corn (Zea mays) grown on the eastern flanks of the Chuska Mountains and floodplain of the San Juan River to the west and north, and (2) spruce (Picea sp.) and fir (Abies sp.) beams from the crest of the Chuska and San Mateo Mountains to the west and south. Here, we extend 87Sr/86Sr analysis to ponderosa pine (Pinus ponderosa) prevalent in the architectural timber at three of the Chacoan great houses (Pueblo Bonito, Chetro Ketl, Pueblo del Arroyo). Like the architectural spruce and fir, much of the ponderosa matches the 87Sr/86Sr ratios of living trees in the Chuska Mountains. Many of the architectural ponderosa, however, have similar ratios to living trees in the La Plata and San Juan Mountains to the north and Lobo Mesa/Hosta Butte to the south. There are no systematic patterns in spruce/fir or ponderosa provenance by great house or time, suggesting the use of stockpiles from a few preferred sources. The multiple and distant sources for food and timber, now based on hundreds of isotopic values from modern and archeological samples, confirm conventional wisdom about the geographic scope of the larger Chacoan system. The complexity of this procurement warns against simple generalizations based on just one species, a single class of botanical artifact, or a few isotopic values.

    The function of the barrier pillar is to protect the mining panel in activity from the abutment load of adjacent mining panels that were mined. In the case of underground mines in Santa Catarina State, the barrier pillar has functioned to protect the main entries of the mine against pillar failure from old mining panels. The objective of this paper is to verify the application of the empirical method to design barrier pillars as proposed by Peng (1986), using numerical simulation following the mining geometry of the coal mines in Santa Catarina State. Two-dimensional numerical models were built taking into account the geometry of the main entries and mining panels for different overburden thickness, and considering the geomechanical properties for the rock mass that forms the roof-pillar-floor system for the Bonito coal vein. The results of the simulations showed that the empirical method to determine the barrier pillar width is valid for the studied coal vein and considered mine geometry. Neither did the pillar at the main entry become overstressed due to adjacent mine panels, nor did the roof present any failure due to stress redistribution. 9 refs., 6 figs., 5 tabs.

    Amino acid and proximate compositions were determined in six raw and cooked marine fish species that are commonly consumed in Turkey. The changes in amino acid and proximate content were found to be significant for all cooking methods in all fish species. Cooking did, in general, significantly increase the contents of essential, semiessential, and other amino acids compared with raw fish species. Grilled Atlantic bonito, anchovy, and bluefish and fried mullet and hake appeared to be more valuable fish dishes for obtaining the officially recommended appropriate daily intake of essential amino acids for humans. Moisture, fat, ash, and carbohydrate contents of raw fish ranged between 48.01% and 83.05%, 0.87% and 30.48%, 1.10% and 1.61%, and 0.09% and 8.70%, respectively. All fresh fish investigated were high in protein: 11.20-17.14 g/100 g. Wide variations in protein content (18.11-25.65 g/100 g) between species and methods of cooking were observed. Fried fish had intermediate fat values, whereas grilled and steamed fishes had a comparatively low value.

  12. Prehistoric deforestation at Chaco Canyon?

    Ancient societies are often used to illustrate the potential problems stemming from unsustainable land-use practices because the past seems rife with examples of sociopolitical "collapse" associated with the exhaustion of finite resources. Just as frequently, and typically in response to such presentations, archaeologists and other specialists caution against seeking simple cause-and effect-relationships in the complex data that comprise the archaeological record. In this study we examine the famous case of Chaco Canyon, New Mexico, during the Bonito Phase (ca. AD 860-1140), which has become a prominent popular illustration of ecological and social catastrophe attributed to deforestation. We conclude that there is no substantive evidence for deforestation at Chaco and no obvious indications that the depopulation of the canyon in the 13th century was caused by any specific cultural practices or natural events. Clearly there was a reason why these farming people eventually moved elsewhere, but the archaeological record has not yet produced compelling empirical evidence for what that reason might have been. Until such evidence appears, the legacy of Ancestral Pueblo society in Chaco should not be used as a cautionary story about socioeconomic failures in the modern world.

    During productive phase of the well, many times there is simultaneous production of the solid particles detached from matrix of the reservoir rock. This phenomenon receives the name of the sand production. In this case stress and flow conditions around of the well are fundamental factors for deflagration of the process. Stress concentration in the wall of the well lead to the loss of cohesion between grains arising, consequently, a granular material region susceptible for dragging by seepage forces derived from fluid flow. The objective of this work was to perform sand production tests in Rio Bonito and synthetic sandstone samples using real-time X-Ray Computerized Tomography. The tests investigated the initial and the evolution of failure at the cavity wall of samples. These are initial stages of the sand production process. The analysis of the CT-scans obtained during tests allowed the visualization of breakouts and collapses of the wells. From studies more details were possible estimate the sand production and produce 3-D images of the propagation of the failure. (author)

    Predatory fish tend to accumulate high levels of mercury (Hg). Food safety assessment of these fish has been carried out on the raw product. However, the evaluation of the risk from Hg concentrations in raw fish might be modified if cooking and bioaccessibility (the contaminant fraction that solubilises from its matrix during gastrointestinal digestion and becomes available for intestinal absorption) were taken into account. Data on Hg bioaccessibility in raw predatory fish sold in Spain are scarce and no research on Hg bioaccessibility in cooked fish is available. The aim of the present study was to evaluate Hg bioaccessibility in various kinds of cooked predatory fish sold in Spain to estimate their health risk. Both Hg and bioaccessible Hg concentrations were analysed in raw and cooked fish (swordfish, tope shark, bonito and tuna). There were no changes in Hg concentrations during cooking. However, Hg bioaccessibility decreased significantly after cooking (42 ± 26% in raw fish and 26 ± 16% in cooked fish), thus reducing in swordfish and tope shark the Hg concentration to which the human organism would be exposed. In future, cooking and bioaccessibility should be considered in risk assessment of Hg concentrations in predatory fish. Copyright © 2011 Society of Chemical Industry.

    Frugivory and seed dispersal have been poorly studied in Neotropical freshwater fishes. We studied frugivory and seed dispersal by the piraputanga fish ( Brycon hilarii, Characidae) in the Formoso River, Bonito, western Brazil. We examined the stomach contents of 87 fish and found the diet of piraputanga consisted of 24% animal prey (arthropods, snails, and vertebrates), 31% seeds/fruits and 45% other plant material (algae/macrophytes/leaves/flowers). The piraputangas fed on 12 fruit species, and were considered as seed dispersers of eight species. Fruits with soft seeds larger than 10 mm were triturated, but all species with small seeds (e.g. Ficus, Psidium) and one species with large hard seed ( Chrysophyllum gonocarpum) were dispersed. Piraputangas eat more fruits in the dry season just before the migration, but not during the spawning season. Fish length had a positive relation with the presence of fruits in their guts. The gallery forest of the Formoso River apparently does not have any plant species that depend exclusively on B. hilarii for seed dispersal because all fruit species are also dispersed by birds and mammals. Based on seed size and husk hardness of the riparian plant community of Formoso River, however, the piraputangas may potentially disperse at least 50% of the riparian fleshy fruit species and may be particularly important for long-distance dispersal. Therefore, overfishing or other anthropogenic disturbances to the populations of piraputanga may have negative consequences for the riparian forests in this region.

    Gangliosides of eye lenses were examined in mammals (rat, rabbits, pig, cow), bird (chicken), reptile (terrapin), amphibian (bullfrog), bony fish (red sea bream, bluefin tuna, bonito, Pacific mackerel) and molluscs (common squid, Pacific octopus). Besides the fact that GM3 was the common ganglioside species, the composition of major gangliosides in mammalian eye lenses significantly differed from each other. While gangliotetraose gangliosides were abundant in rat eye lens, they did not constitute major components in porcine and bovine tissues. The c-series ganglioside GT3 was expressed in rat eye lenses but were practically absent in other mammalian tissues. The composition of major gangliosides in eye lenses of lower animals varied from species to species, whereas c-series gangliosides were consistently expressed, showing similar compositional profiles. Our results demonstrate the species-specific compositions of lenticular gangliosides. Evidence was also provided suggesting that eye lenses of common squid (Todarodes pacificus) and Pacific octopus (Octopus vulgaris) express gangliosides including gangliotetraose species and c-series gangliosides.

    The aims of this study were to carry out a serological survey of canine leishmaniasis and identify the phlebotomine fauna in the urban area of Bonito, Mato Grosso do Sul. The serological survey was conducted on a sample of 303 dogs, by means of the indirect immunofluorescence test. Phlebotomines were captured using automated light traps. The serological survey found that 30% of the dogs were seropositive, both from the center and from all districts of the town. A total of 2,772 specimens of phlebotomines were caught and the species most found was Lutzomyia longipalpis (90.4%), which corroborated its role as the vector of for canine visceral leishmaniasis in the region. Phlebotomines of the species Bichromomyia flaviscutellata (the main vector for Leishmania (Leishmania) amazonensis) and Nyssomyia whitmani (the vector for Leishmania (Viannia) brasiliensis) were also caught. The findings indicate the need for continuous epidemiological surveillance, with attention towards diminishing the vector breeding sites and the transmission of these diseases in that region.

    The R and D project is implemented for design, fabrication and installation of ocean-based artificial deep ocean water (DOW) upwelling devices which can take DOW at low cost in an ocean; experiments for enhancing productivity of ocean by adding DOW using mesocosms; and studying the biological effects of DOW for keeping freshness of marine products. DOW is successfully taken by the upwelling system from a depth of 800 m in a sea area 2,000 m or more in depth. The system has worked to perform its functions even when attacked by typhoons, which caused wave height of 10 m or more. For enhancing productivity of ocean, the culture experiments are conducted in a small-size, on-shore tank, and the mesocosm experiments in a harbor. The results indicate that addition of DOW increases the phytoplankton phase and its quantity. It is also observed that addition of iron ion further accelerates the fertilizing effect. The results of the experiments conducted in a harbor also indicate that DOW has the fertilizing effect, even in a very small quantity, increasing quantity of small zooplankton. No definite effect of DOW, liquid or ice, is observed for keeping freshness of sliced raw sea bream and bonito. (NEDO)

    The aim of this study was to apply Bayesian models to the Fourier-transform infrared spectroscopy spectra of individual sheep milk samples to derive calibration equations to predict traditional and modeled milk coagulation properties (MCP), and to assess the repeatability of MCP measures and their predictions. Data consisted of 1,002 individual milk samples collected from Sarda ewes reared in 22 farms in the region of Sardinia (Italy) for which MCP and modeled curd-firming parameters were available. Two milk samples were taken from 87 ewes and analyzed with the aim of estimating repeatability, whereas a single sample was taken from the other 915 ewes. Therefore, a total of 1,089 analyses were performed. For each sample, 2 spectra in the infrared region 5,011 to 925 cm -1 were available and averaged before data analysis. BayesB models were used to calibrate equations for each of the traits. Prediction accuracy was estimated for each trait and model using 20 replicates of a training-testing validation procedure. The repeatability of MCP measures and their predictions were also compared. The correlations between measured and predicted traits, in the external validation, were always higher than 0.5 (0.88 for rennet coagulation time). We confirmed that the most important element for finding the prediction accuracy is the repeatability of the gold standard analyses used for building calibration equations. Repeatability measures of the predicted traits were generally high (≥95%), even for those traits with moderate analytical repeatability. Our results show that Bayesian models applied to Fourier-transform infrared spectra are powerful tools for cheap and rapid prediction of important traits in ovine milk and, compared with other methods, could help in the interpretation of results.

    The importance of milk coagulation properties for milk processing, cheese yield, and quality is widely recognized. The use of traditional coagulation traits presents several limitations for testing bovine milk and even more for sheep milk, due to its rapid coagulation and curd firming, and early syneresis of coagulum. The aim of this technical note is to test and improve model fitting for assessing coagulation, curd firming, and syneresis of sheep milk. Using milk samples from 87 Sarda ewes, we performed in duplicate lactodynamographic testing. On each of the 174 analyzed milk aliquots, using 180 observations from each aliquot (one every 15 s for 45 min after rennet addition), we compared 4 different curd firming models as a function of time (CF t , mm) using a nonlinear procedure. The most accurate and informative results were observed using a modified 4-parameter model, structured as follows: [Formula: see text] , where t is time, RCT eq (min) is the gelation time, CF P (mm) is the potential asymptotical CF at an infinite time, k CF (%/min) is the curd firming rate constant, and k SR (%/min) is the curd syneresis rate constant. To avoid nonconvergence and computational problems due to interrelations among the equation parameters, CF P was preliminarily defined as a function of maximum observed curd firmness (CF max , mm) recorded during the analysis. For this model, all the modeling equations of individual sheep milk aliquots were converging, with a negligible standard error of the estimates (coefficient of determination >0.99 for all individual sample equations). Repeatability of the modeled parameters was acceptable, also in the presence of curd syneresis during the lactodynamographic analysis. Copyright © 2018 American Dairy Science Association.

    Full Text Available In a long term supplementation trial (10 weeks, the effects of the inclusion of whole extruded linseed in the diet of dairy ewes on milk and cheese fatty acid composition were evaluated. Two groups of 24 Sarda ewes in early lactation were randomly assigned to control concentrate (800 g/d concentrate, C or whole extruded linseed concentrate (L, 700 g/d, with 30% of extruded linseed, Omega-Lin®. Results showed that, after 2 weeks on the L diet, the milk content of unsaturated fatty acid (UFA, including rumenic acid (RA, vaccenic acid (VA and alfa-linolenic acid (ALA increased sharply compared to C group, reaching the highest levels after 7-8 weeks (3.06, 7.31 and 2.31 g/100 g milk fat for RA, VA and ALA, respectively. During the last 2 weeks of the experimental period, when pasture was included in the diet of both groups, the content of the above fatty acids slightly decreased in milk from L group, whereas in milk from C group increased. Nevertheless, the average content of these fatty acids in milk from L group remained significantly higher than that of milk from C group. Compared with the control, the L diet resulted in a significant reduction (-17% in the concentration of saturated fatty acid in milk. The fatty acid content of the cheese obtained from milk of the two groups reflected the milk fatty acid composition. The inclusion of extruded linseed in the diet of dairy ewes improved the nutraceutical properties of milk and cheese, but further researches are needed in order to better understand the relationship between basal diet and lipid supplementation in dairy ewes.

    This work is a study of the 40 K and the 238 U and 232 Th series radioactivity in rocks measured with high resolution gamma ray spectrometry. The rocks were taken from the geologic formations in the region of the Tibagi river hydrographic basin. The course of this river cuts through the Paleozoic and Mesozoic stratigraphic sequences of the Parana sedimentary basin. In order to take into account the background radiation attenuation by the samples, a technique was developed that eliminated the need to measure a blank sample. The effects of the radiation's self-attenuation in the sample matrix were taken into account by using a gamma ray direct transmission method. The results for 87 rock samples, taken from 14 distinct formations, and their corresponding radioactivity variations are presented and discussed according to the possible geological processes from which they originated. Among the most discussed results are: an outcrop that profiles shale, limestone and rhythmite in the Irati Formation; a sandstone and siltstone sequence from the Rio do Rasto Formation; and a profile sampled in a coal mine located in the Rio Bonito Formation. The calculations of the rocks' contributions to the outdoor gamma radiation dose rate agree with the values presented by other authors for similar rocks. The highest dose values were obtained from felsic rocks (rhyolite of the Castro group, 129.8 ± 3.7 nGy.h -1 , and Cunhaporanga granite, 167 ± 37 nGy.h -1 ). The other highest values correspond to the shale rocks from the Irati Formation (109 ± 16 nGy.h -1 ) and the siltic shale rocks from the Ponta Grossa Formation (107.9 ± 0.7 nGy.h -1 ). The most recent geological formations presented the lowest dose values (e.g. the Botucatu sandstone, 3.3 ± 0.6 nGy.h -1 ). The average value for sedimentary rocks from seven other formations is equal to 59 ± 26 nGy.h -1 . The Rio Bonito Formation presented the highest dose value (334 ± 193 nGy.h -1 ) mainly due to the anomalous 226 Ra

    Full Text Available Sixteen common bean cultivars were compared concerning the physicochemical characteristics of their raw seeds in the course of two consecutive harvests, as well as the effect of storage conditions on starch and dietary fiber content of cooked beans. Using cluster analysis it was possible to identify groups of cultivars with different nutritional features. Bean cultivars were categorized into four different groups according either to their macronutrient content (crude protein-PROT, total dietary fiber-TDF, insoluble dietary fiber-IDF, soluble dietary fiber-SDF, digestible starch-DS, and resistant starch-RS or to their micronutrient levels (Fe, Zn, Mn, Cu, Ca, Mg, and P. Guateian 6662 and Rio Tibagi appeared to be the most suitable cultivars to prevent nutritional deficiencies, because they had high PROT, DS, Fe, and Zn content. The high total dietary fiber and RS content of Iraí, Minuano, and TPS Bonito cultivars, and specially the high soluble fiber content of Guateian 6662 and Rio Tibagi cultivars suggests that they could have a beneficial role in controlling blood lipid and glucose levels. Cooked beans had a decrease in DS and an increase in RS content after storage (4 °C or -20 °C, but these changes were more prominent in beans that had low RS content before cooking than in those of high RS content. TDF, IDF, and SDF did not change after storage.Compararam-se as características físico-químicas de dezesseis cultivares de feijão-comum cru ao longo de duas safras consecutivas, assim como se avaliou o efeito das condições de armazenagem nos teores de amido e fibra alimentar em grãos cozidos.

    Ion chromatography-ultra violet-hydride generation-Atomic Florescence Spectrometry was applied to detect 5 arsenic species in seafoods. The arsenic species studied include arsenobetaine (AsB), arsenite (As(III)), dimethylarsinic acid (DMA), monomethylarsonic acid (MMA), and arsenate (As(V)), which were extracted from samples using 2% formic acid. Gradient elution using 33 mmol L-1 CH3COONH4 and 15 mmol L-1 Na2CO3 with 10 mL CH3CH2OH at pH 8.4 allowed the chromatographic separation of all the species on a Hamilton PRP-X100 anion-exchange column in less than 8 min. In this study, an ultrasound extraction method was used to extract arsenic species from seafood. The extraction efficiency was good and the recoveries from spiked samples were in the range of 72.6%-109%; the precision between sample replicates was higher than 3.6% for all determinations. The detection limits were 3.543 μg L-1 for AsB, 0.426 μg L-1 for As(III), 0.216 μg L-1 for DMA, 0.211 μg L-1 for MMA, and 0.709 μg L-1 for As(V), and the linear coefficients were greater than 0.999. We also developed an application of this method for the determination of arsenic species in bonito, Euphausia superba, and Enteromorpha with satisfactory results. Therefore, it was confirmed that this method was appropriate for the detection of arsenic species in seafood.

    In the present study, the thermoluminescence (TL) method (EN1788) was used to detect the irradiation treatment of Japanese traditional seasoning mixes mainly composed of dried fish (bonito etc.) and its extract. The Glow 1 curves of minerals separated from the seasoning mixes using a heavy liquid showed significant single peaks at temperatures between 146.5degC and 175.4degC. The peaks are typical for irradiated food, despite the samples being not irradiated. The Glow 2 curves showed single peaks at temperatures higher than that of the Glow 1 curves (175.4degC to 217.9degC). The peak temperature of Glow 2 is usually lower than that of Glow 1 because the peaks from irradiated silicate minerals shift to higher temperatures with time. The TL glow ratios (Glow1/Glow2) calculated in the temperature ranges (167-232degC) defined by means of irradiated TLD-100 were above 0.1, suggesting that the mineral samples were contaminated with organic materials such as protein or bio-inorganic materials such as bone. In order to remove the possible contaminants, acid hydrolysis and subsequent heavy liquid separation were employed. The minerals thus obtained showed no Glow 1 peaks. A significant peak was observed at 213degC instead of peaks at lower temperature for the case of irradiated seasoning mixes (2.45 kGy). These results suggest that the TL method may provide false positives for the Japanese traditional seasoning mixes because of luminescence from some components other than silicate minerals. It appears that EN1788 needs some modification to precisely detect food irradiation for the seasoning mixes. (author)

    Full Text Available BACKGROUND: Lutzomyialongipalpis (Diptera: Psychodidae is the major vector of Leishmania (Leishmania infantum and thus plays a crucial role in the epidemiology of American visceral leishmaniasis (AVL. This vector is the best studied species of sand fly in the Neotropical region. Many studies claim that this vector is in fact a species complex; however there is still no consensus regarding the number of species that belong into this complex or the geographical distribution of sibling species. The aim of the present study was to analyze the genetic relationships within Lu. longipalpis populations in the state of Mato Grosso do Sul (MS, Brazil. METHODOLOGY/PRINCIPAL FINDINGS: We collected 30 Lu. longipalpis (15 females and 15 males from five localities (Campo Grande, Três Lagoas, Aquidauana, Miranda and Bonito and 30 Lu. Cruzi from Corumbá, totaling 180 sandflies from MS, and 30 Lu. longipalpis from Estrela de Alagoas, state of Alagoas (AL, Northeast Brazil. We show that eight previously described microsatellite loci were sufficient in distinguishing Lu. longipalpis from Lu. Cruzi, which is a closely related species, and in differentiating between Lu. longipalpis collected in MS versus Estrela de Alagoas. Analyses of the genotypes revealed introgression between sympatric Lu. longipalpis and Lu. Cruzi. CONCLUSIONS/SIGNIFICANCE: Our findings support the hypothesis of cryptic species within the Lu. longipalpis complex. Furthermore, our data revealed introgression between Lu. longipalpis and Lu. cruzi. This phenomenon should be further investigated to determine the level and incidence of hybridization between these two species. We also demonstrated that microsatellite markers are a powerful tool for differentiating sand fly populations and species. The present study has elucidated the population structure of Lu. longipalpis in MS and, by extension, the Neotropical Lu. longipalpis complex itself.

    The Magdalena river turtle, Podocnemis lewyana, is an endangered and endemic turtle from Colombia. Among the most important information needed to conserve endangered species is to identify, monitor, and protect the sites used by the species to reproduce and grow. In this study we report, for the first time, the reproductive output and the nesting beaches of P. lewyana in the Claro Cocorna Sur River, a tributary of the Magdalena river drainage. We systematically examined a river transect of 8 km with 14 sandy beaches during two nesting seasons in one year. We recorded a yearly production of 47 clutches, 957 eggs, and two preferred nesting beaches: Alto Bonito with 51 %, and Belgica with 28.3 % of this reproductive output. Aafuver, a community-based organization, has led a headstarting program since 2010 to decrease in-situ egg mortality due to predation on nesting beaches. Aafuver collects and incubates the eggs ex-situ, raises the hatchlings for one to five months and then releases them into the same river. To understand potential effects of such egg manipulation, we monitored and compared in-situ and ex-situ incubation temperatures. We found ex-situ temperatures below the pivotal temperature known for P. lewyana and below the temperatures in nesting beaches. Finally, we monitored hatchlings growth under aafuver captive conditions, and found that hatchlings duplicated their body mass during the first three months of age. Egg weight was strongly associated to body weight at hatching; however this association is lost by the third month of age. We strongly encourage supporting this community-based conservation program, and the protection of the Claro Cocorna Sur River as an important nesting and growth habitat for the conservation of P. lewyana.

    Concentrations of trace elements in several foodstuffs collected in Japan were analyzed by neutron activation analysis (NAA), inductively-coupled plasma atomic emission spectrometry (ICP-AES) and anodic striping voltametry (ASV). The elements analyzed were as follows: Zn, Se, As, Hg, Cs, Cr, Co, Fe, Rb, Br and K by NAA; Mn, Ba, Sr, Mg, Ca, P, K, Zn, Cu and Fe by ICP-AES; and Pb, Cd, Cu and Zn by ASV. Because of the high consumption of rice in Japan, the focus of analysis was on this foodstuff. Concentrations of K, Mg, Mn, P and Zn in different polished rice samples were similar, whereas those of Br, Co, Cs, Rb and Se varied. Levels of toxic elements in polished rice were generally lower than those in other foodstuffs. The highest concentrations of As, Hg, Se and Zn were found in marine products, i.e.. Hijiki-algae (As: 59 mg/kg, dry), tuna (Hg: 1.1 mg/kg, dry), bonito (Se: 4.5 mg/kg, dry) and oysters (Zn: 350 mg/kg, dry). Dietary intakes of As, Ca, Cd, Cu, Fe, Hg, K, Mg, Mn, P, Pb, Se and Zn by Japanese were estimated by using these analytical results and published food consumption data in Japan. We have also identified the major sources of the elements in dietary intakes as follows: (a) about 90% of the As was derived from marine products (fish and seaweed); (b) about 70% of the Hg was derived from fish; (c) about 40-60% of the Cd and the Mn and 20-40% of the Zn, Cu and Mg was derived from rice; (d) selenium was mostly derived from fish, meat and eggs; (e) more than 20% of the Ca was derived from milk and milk products; (f) elements such as Fe, K, P and Pb was derived from different sorts of foodstuffs.

    Coalbed methane (CBM) is a worldwide exploration target of the petroleum industry. In Brazil, the most important coal-bearing succession is associated with the Permian Rio Bonito Formation of the Parana Basin. The gas-prone areas are located at the southeastern margin of the Parana Basin and possibly in the offshore region of the northern part of the Pelotas Basin. Coalfields end abruptly at the present day shoreline, a result of rifting of Gondwana and the evolution of the South Atlantic Ocean. All geologic indicators suggest that in pre-rift times the coal seams extended further eastwards, probably now lying deeply buried below the sedimentary succession of the Pelotas Basin. The present paper discusses structural, stratigraphic, seismic and aeromagenetic data that support the preservation of continental crust beneath ocean sediment. If the coal beds had similar lateral extent to known onshore coals, and coal beds extended across the projected extension of the Parana basin, and there was a conservative 5 m of cumulative coal thickness, then a potential methane volume can be estimated for this newly inferred resource. Average onshore coal gas content is 32 scf/ton (1.00 m(3)/ton). If this is similar in the offshore coal deposits, then the hypothetical methane volume in the offshore area could be in excess of 1.9 x 10(12) scf (56 x 10(9) m(3)). Metamorphism from dikes associated with rifting are potential complicating factors in these deposits, and since no borehole reaching the deep-lying strata in the offshore area are available, this is a hypothetical gas resource with a certain level of uncertainty which should be tested in the future by drilling a deep borehole.

    Sorafenib (SFN) is an anti-angiogenic chemotherapeutic that prolongs survival of patients with hepatocellular carcinoma (HCC); its side effects, including vascular damages such as hand-foot syndrome (HFS), are a major cause of therapy discontinuation. We previously reported that maintenance of peripheral blood flow by intake of dried bonito broth (DBB) significantly prevented HFS and prolonged the administration period. The amino acids contained in DBB probably contribute to its effects, but the mechanism has not been clarified. We hypothesized that histidine, the largest component among the amino acids contained in DBB, has effects on SFN-induced vascular damage, and evaluated this possibility using a novel medaka fish model. The fli::GFP transgenic medaka fish model has a fluorescently visible systemic vasculature. We fed the fish with SFN with and without histidine to compare blood flow and vascular structure among the differently fed models. The vascular cross-sectional area of each fish was measured to determine vascular diameter changes. Our results demonstrated that SFN-fed medaka developed a narrower vascular diameter. In addition, this narrowing was counteracted by addition of histidine to the medaka diet. We observed no positive effect of histidine on regeneration of cut vessels or on cell growth of endothelial cells and HCC cell lines. We proved the efficacy of the medaka model to assess vascular changes after administration of specific chemicals. And our results suggest that SFN causes vascular damage by narrowing peripheral vessel diameter, and that histidine effectively counteracts these changes to maintain blood flow.

The results of stomach contents analysis were expressed with the frequency of occurrence and gravimetric method, combined in the Alimentary Index (AI. The 20 species studied consumed 52 food items, grouped in 10 food categories: aquatic insects, terrestrial insects, crustaceans, fish, macroinvertebrates, microcrustaceans, algae, vegetal matter, detritus/sediment and scales. The aquatic insects (mainly Chironomidae, Odonata and Ephemeroptera were the most common food resources, consumed by 18 species. The diet composition of the community (species grouped indicated that the dominant food category in the diet of fishes was aquatic insects (AI = 77.6%, followed by crustaceans (AI = 7.1%. Four trophic guilds were identified according a cluster analysis (Pearson distance: insectivorous (10 species, omnivorous (4 species, detritivorous (3 species and piscivorous/carcinophagous (3 species. Despite the highest number of species, the insectivorous guild was responsible for more than 80% in captures in number and biomass (CPUEn and CPUEb. The low values of niche breadth presented by all species, along with the low values of diet overlap between species pairs indicate a high degree of food resources partitioning among species. The aquatic insects, despite being the main food resource of insectivorous fishes, also complemented the diet of other species, which demonstrate the importance of this food resource for the fish community, sustaining a high diversity, abundance and biomass of fishes.

  11. Methodology of the carbonates dating by the uranium series unbalance by mass spectrometry

    There are many dating methods largely used according to the kind of material to be dated. Methods that rely on the time-dependency of geochemical disequilibrium between daughter and parent isotope, from the '2 38 U, 235 U and 232 Th natural decay system, whose final members are stable Pb isotopes, are the most useful in a broader variety of geological, hydrological and archaeological problems. The use of this method in cave deposits like speleothems and clastic sediments proved to be a powerful tool to study past climatic and environmental changes. Speleothems like stalagmites are frequently used in paleoenvironmental interpretations. This method may be applied to rocks and underground water dating, erosion studies, transport and sedimentation processes, interactions between rock-groundwater, among others. The present work focuses on the chemical preparation of the U-Th method including the chemical procedures to avoid laboratory contamination and the mass spectrometer precise calibration in order to get high reproducibility. The process has many steps: samples preparation; digestion and chromatographic separation using standards and samples already dated in other laboratories; determination of the isotopic ratios by mass spectrometers, and a case study based on a stalagmite from Joao Arruda cave, Bonito, Mato Grosso State, Brazil. The obtained data shows the reliability of the method works, mostly in relation to co precipitation of U and Th and to the chromatographic separation of these metals. It is also observed that the obtained dates are within the errors for each sample and are very similar to the dates obtained in other laboratories (validated to this methodology). Further improvements are necessary to achieve better results, mostly related to the reading method in the MC-ICP-MS. The case study in the JA-5 stalagmite shows that it stopped growing around 2,0 ky. This is a different result from that obtained on JA-3 stalagmite, from the same cave, but placed

    In the Leao-Butia Coalfield, Rio Grande do Sul the coal seams occur in the Rio Bonito Formation, Guata Group, Tubarao Supergroup of the Parana Basin, Brazil and are of Permian (Artinskian-Kungurian) age. This study is the first detailed investigation on the coal petrographic characterization of the coal-bearing sequence in relation to the depositional settings of the precursor mires, both in terms of whole seam characterization and in-seam variations. The study is based on the analyses of nine coal seams (I2, CI, L4, L3, L2, L1, S3, S2, S1), which were selected from core of borehole D-193, Leao-Butia and represent the entire coal-bearing sequence. The interpretation of coal facies and depositional environment is based on lithotype, maceral and microlithotype analyses using different facies-critical petrographic indices, which were displayed in coal facies diagrams. The seams are characterized by the predominance of dull lithotypes (dull, banded dull). The dullness of the coal is attributed to relatively high mineral matter, inertinite and liptinite contents. The petrographic composition is dominated by vitrinite (28-70 vol.% mmf) and inertinite (> 30 vol.% mmf) groups. Liptinite contents range from 7 to 30 vol.% (mmf) and mineral matter from 4-30 vol.%. Microlithotypes associations are dominated by vitrite, duroclarite, carbominerite and inertite. It is suggested that the observed vertical variations in petrographic characteristics (lithotypes, microlithotypes, macerals, vitrinite reflectance) were controlled by groundwater level fluctuations in the ancient mires due to different accommodation/peat accumulation rates. Correlation of the borehole strata with the general sequence-stratigraphical setting suggests that the alluvial fan system and the coal-bearing mudstone succession are linked to a late transgressive systems tract of sequence 2. Based on average compositional values obtained from coal facies diagrams, a deposition in a limno-telmatic to limnic coal

    Full Text Available The research article discusses the concept of “the trans-avant-garde” (a term coined by the Italian art critic Achille Bonito Oliva to describe certain phenomena in visual arts, especially painting, which have appeared since the end of the 1970s and attempts to adapt it for a discussion of twentieth century Polish music.

    Background Lutzomyia longipalpis (Diptera: Psychodidae) is the major vector of Leishmania (Leishmania) infantum and thus plays a crucial role in the epidemiology of American visceral leishmaniasis (AVL). This vector is the best studied species of sand fly in the Neotropical region. Many studies claim that this vector is in fact a species complex; however there is still no consensus regarding the number of species that belong into this complex or the geographical distribution of sibling species. The aim of the present study was to analyze the genetic relationships within Lu. longipalpis populations in the state of Mato Grosso do Sul (MS), Brazil. Methodology/Principal Findings We collected 30 Lu. longipalpis (15 females and 15 males) from five localities (Campo Grande, Três Lagoas, Aquidauana, Miranda and Bonito) and 30 Lu. Cruzi from Corumbá, totaling 180 sandflies from MS, and 30 Lu. longipalpis from Estrela de Alagoas, state of Alagoas (AL), Northeast Brazil. We show that eight previously described microsatellite loci were sufficient in distinguishing Lu. longipalpis from Lu. Cruzi, which is a closely related species, and in differentiating between Lu. longipalpis collected in MS versus Estrela de Alagoas. Analyses of the genotypes revealed introgression between sympatric Lu. longipalpis and Lu. Cruzi. Conclusions/Significance Our findings support the hypothesis of cryptic species within the Lu. longipalpis complex. Furthermore, our data revealed introgression between Lu. longipalpis and Lu. cruzi. This phenomenon should be further investigated to determine the level and incidence of hybridization between these two species. We also demonstrated that microsatellite markers are a powerful tool for differentiating sand fly populations and species. The present study has elucidated the population structure of Lu. longipalpis in MS and, by extension, the Neotropical Lu. longipalpis complex itself. PMID:24066129

    Listeria monocytogenes is of major concern in the fermented meat products and is able to persist in their processing environments. The aim of the present work was to evaluate the virulence profile and the persistence capacity of L. monocytogenes strains isolated in Sardinian fermented sausages processing plants. Food (ground meat, sausages at the end of acidification and ripening stage) and environmental samples (a total of n. 385), collected from 4 meat processing plants located in Sardinia (Italy), were examined to detect L. monocytogenes presence. All the L. monocytogenes isolates were identified by polymerase chain reaction (PCR) method. A subset of strains was also characterised by multiplex PCR-based serogrouping, using the lmo0737 , lmo1118 , ORF2819 and ORF2110 genes. Three different multiplex PCRs were used to obtain the virulence profiles by the rrn , hlyA , actA , prfA , inlA , inlB , iap , plcA , plcB and mpl marker genes. Furthermore, in vitro biofilm forming ability and resistance to disinfectants were carried out on microtiter plate. The overall prevalence was 31.5% in food, and 68.5% in environmental samples. The prevalent serotype resulted 1/2c (43%), followed by 1/2a (40%), 4b (8.6%), and 1/2b (8.6%). The amplification products of the virulence genes were found in all the isolates with the following prevalence: 77.1% hlyA ; 100% rrn ; 100% prfA ; 97.1% iap ; 65.7% inlB ; 88.6% inlA ; 100% plcA ; 100% plcB and 74.3% mpl . As for biofilm forming ability, 37.1% of the strains were positive and resulted weak producer, but all the isolates were sensible to disinfectants showing a reduction of L. monocytogenes growth after each incubation time. More appropriate technologies and application of measures of hygienic control should be implemented to prevent the L. monocytogenes growth and cross-contamination in salsiccia sarda processing plants.

    Full Text Available This paper presents the first results of the Tunisian- Spanish research project in Utica (Tunisia, in particular the finds recovered from a well (possibly closed ritually linked to a partially excavated building. The well’s interior is a deposit composed of bones of consumed animals and Phoenician, Geometric Greek, Sardinian, Lybian, Villanovaan and Tartessian pottery, principally formed by drinking cups and plates, as well as amphorae. The finds bear witness to early Phoenician networks of exchange in the Central and Western Mediterranean and to a very ancient Phoenician settlement. The dates of C14 obtained from seeds from the well’s fill indicate a chronology around 925-900 cal BC. These dates are identical to those of early Phoenician foundations in the Iberian Peninsula at Huelva, Carambolo and La Rebanadilla. As a whole they define the most ancient horizon of the Phoenician colonization in Central and Western Mediterranean.Se presentan los primeros resultados del proyecto de investigación tunecino-espa.ol en Utica (Túnez.

    The distribution of noble gas isotopic compositions in the mantle provides important constraints on the large-scale mantle evolution, as noble gases can trace the interaction between degassed, or processed, mantle domains and undegassed, or primitive, mantle domains. Data from the radiogenic He, Ne, Ar and Xe isotopic systems have shown that plume-related lavas sample relatively undegassed mantle domains, and the recent identification of isotopic anomalies in the short-lived I-Xe and Hf-W isotopic systems in plume-related lavas further suggests that these domains may be ancient, dating back to Earth's accretion. However, little is known about the potential variability of the heavy noble gas systems and the distribution of undegassed domains in the ambient upper mantle not influenced by plumes. Here, we present new high-precision He, Ne, Ar, and Xe isotopic data for a series of MORBs from a depleted section of the subtropical north Mid-Atlantic Ridge, distant from any known plume influence. Some samples have extremely low (unradiogenic) 4He/3He, 21Ne/22Ne, 40Ar/36Ar, and 129Xe/130Xe ratios, including some of the lowest values ever determined for MORBs. Such unradiogenic compositions are reminiscent of OIBs and plume-influenced E-MORBs, suggesting the presence of a relatively undegassed or primitive reservoir in the source of these depleted MORBs. The He, Ne, and Ar isotopic systems are sensitive to the long-term degassing history, suggesting that this domain in the MORB source is ancient. The 129Xe/130Xe ratio is sensitive to degassing only during the first 100 Ma of Earth history, suggesting that some of the isotopic character of these samples has been preserved since Earth's accretion. Together, these observations suggest that primordial or undegassed material is not only sampled in plumes-related lavas, but also normal, depleted MORBs. Along with data from E-MORBs in the southern EPR (Kurz et al., 2005), southern MAR (Sarda et al., 2000), and equatorial MAR

    Full Text Available Besults are presented of mineral fertilizer trials witht Irish potato crop in the State of São Paulo. The experiments were conducted in the flat lands of the Paraíba River banks. In this region, potato plantings are usually made from May to October, a period with little rain, :nul practically free from flood. From October to April, when good weather conditions prevail, rice is almost the only crop grown. Iu other regions of the State, potato is planted in February or in August. Chemical analyses of an average sample of the soil revealed a high organic matter content, about seven fold higher total nitrogen content and a twelve fold higher total carbon content, as compared with those found in a soil sample taken from Capão Bonito, an important potato area in the State, where phosphoric acid has been found to be responsible for increases in tuber productions. The experimental design was arranged so that conclusions could be drawn from the influence of increasing amounts of each nutrient element N, P and K, in the presence of a constant amount of the other two. In spite of the high total nitrogen content of the soil, results have shown this element not to he in available form for plants. In these experiments, application of nitrogen has been found to be effective and even decisive in increasing tuber yield. Lack of this element results in a lower production, in some cases, even inferior to check plots. In experiment n.° 38, for instance, PK yielded two tons of tubers per hectar, whereas NK and NP yielded, respectively, 1.1.9 and 12.4 tons. In another trial, n.° 40 BK yielded 10.5 tons per hectar (less than check, while NPK yielded 16.2 tons. From the economical point of view, an amount of 80 kg of N to the hectar in the presence of PK, brougth better profits, application of PK alone, resulted in losses. Determinations of starch content in tubers of every treatment have shown no appreciable differences between them.

    We describe the spatial and temporal patterns of timber acquisition by great house builders in Chaco Canyon, New Mexico. The 87Sr/86Sr ratios from annually-dated, architectural logs in 10^{th} to 12^{th} century structures are compared to the 87Sr/86Sr of modern tree stands from the surrounding mountains. Although not a stable isotope system, the long half-life of the 87Sr parent (87Rb, t1/2 = 48.8 Ga) yields a stable isotope system on the timescales used to determine the geographic origin of ecosystem resources. The small mass difference among strontium's isotopes eliminates measurable biologic or kinetic fractionation at earth surface conditions. Strontium tracer studies, however, do require distinct end-member ratios to be feasible. Strontium isotopes, alone or in combination with other isotopes, provide a simple way to study and trace the geographic origin of ecosystem resources. Over the 150 km-wide Chaco Basin, 87Sr/86Sr ratios of modern trees range from 0.7055 to 0.7192. 87Sr/86Sr ratios from this and other studies show that during great house construction Chaco Canyon was provisioned with plant materials that came from more than 75 km away in all directions. This includes (1) corn (Zea mays) grown on the eastern flanks of the Chuska Mountains and floodplain of the San Juan River to the west and north, (2) spruce (Picea sp.) and fir (Abies sp.) architectural beams from the high crests of the Chuska and San Mateo Mountains to the west and south, and (3) ponderosa pine (Pinus ponderosa) from the low slopes of the La Platas and San Juan Mountains to the north, the San Pedro Mountains to the east, the Chuska and San Mateo Mountains and nearby mesas. There are no systematic patterns in spruce/fir or ponderosa provenance by great house (Pueblo Bonito, Chetro Ketl, Pueblo del Arroyo) or by time, suggesting the use of stockpiles from a few preferred sources from the beginning of large scale construction in or around Chaco Canyon. This is contrary to the view that

    Full Text Available Abstract Background DNA barcodes are a global standard for species identification and have countless applications in the medical, forensic and alimentary fields, but few barcoding methods work efficiently in samples in which DNA is degraded, e.g. foods and archival specimens. This limits the choice of target regions harbouring a sufficient number of diagnostic polymorphisms. The method described here uses existing PCR and sequencing methodologies to detect mitochondrial DNA polymorphisms in complex matrices such as foods. The reported application allowed the discrimination among 17 fish species of the Scombridae family with high commercial interest such as mackerels, bonitos and tunas which are often present in processed seafood. The approach can be easily upgraded with the release of new genetic diversity information to increase the range of detected species. Results Cocktail of primers are designed for PCR using publicly available sequences of the target sequence. They are composed of a fixed 5' region and of variable 3' cocktail portions that allow amplification of any member of a group of species of interest. The population of short amplicons is directly sequenced and indexed using primers containing a longer 5' region and the non polymorphic portion of the cocktail portion. A 226 bp region of CytB was selected as target after collection and screening of 148 online sequences; 85 SNPs were found, of which 75 were present in at least two sequences.

    DNA barcodes are a global standard for species identification and have countless applications in the medical, forensic and alimentary fields, but few barcoding methods work efficiently in samples in which DNA is degraded, e.g. foods and archival specimens. This limits the choice of target regions harbouring a sufficient number of diagnostic polymorphisms. The method described here uses existing PCR and sequencing methodologies to detect mitochondrial DNA polymorphisms in complex matrices such as foods. The reported application allowed the discrimination among 17 fish species of the Scombridae family with high commercial interest such as mackerels, bonitos and tunas which are often present in processed seafood. The approach can be easily upgraded with the release of new genetic diversity information to increase the range of detected species. Cocktail of primers are designed for PCR using publicly available sequences of the target sequence. They are composed of a fixed 5' region and of variable 3' cocktail portions that allow amplification of any member of a group of species of interest. The population of short amplicons is directly sequenced and indexed using primers containing a longer 5' region and the non polymorphic portion of the cocktail portion. A 226 bp region of CytB was selected as target after collection and screening of 148 online sequences; 85 SNPs were found, of which 75 were present in at least two sequences. Primers were also designed for two shorter sub-fragments that could be amplified from highly degraded samples. The test was used on 103 samples of seafood (canned tuna and scomber, tuna salad, tuna sauce) and could successfully detect the presence of different or additional species that were not identified on the labelling of canned tuna, tuna salad and sauce samples. The described method is largely independent of the degree of degradation of DNA source and can thus be applied to processed seafood. Moreover, the method is highly flexible

    Full Text Available Soil management influences the chemical and physical properties of soil. Chemical conditions have been thoroughly studied, while the role of soil physical conditions regarding crop yield has been neglected. This study aimed to analyze the wheat yield and its relationship with physical properties of an Oxisol under no-tillage (NT. The study was carried out between 2010 and 2011, in Reserva do Iguaçu, State of Paraná, Brazil, on the Campo Bonito farm, after 25 years of NT management. Based on harvest maps of barley (2006, wheat (2007 and maize (2009 of a plot (150 ha, zones with higher and lower yield potential (Z1 and Z2, respectively were identified. Sampling grids with 16 units (50 x 50 m and three sampling points per unit were established. The wheat grain yield (GY and water infiltration capacity (WIC were evaluated in 2010. Soil samples with disturbed and undisturbed structure were collected from the 0.00-0.10 and 0.10-0.20 m layers. The former were used to determine soil organic carbon (Corg levels and the latter to determine soil bulk density (BD, total porosity (TP, macroporosity (Mac, and microporosity (Mic. Soil penetration resistance (PR and water content (SWC were also evaluated. The wheat GY of the whole plot was close to the regional average and the yield between the zones differed significantly, i.e. 22 % higher in Z1 than in Z2. No significant variation in Mic was observed between zones, but Z1 had higher Corg levels, SWC, TP and Mac and lower BD than Z2 in both soil layers, as well as a lower PR than Z2 in the 0.00-0.10 m layer. Therefore, soil physical conditions were more restrictive in Z2, in agreement with wheat yield and zone yield potential defined a priori, based on the harvest maps. Soil WIC in Z1 was significantly higher (30 % than in Z2, in agreement with the results of TP and Mac which were also higher in Z1 in both soil layers. The correlation analysis of data of the two layers showed a positive relationship between

    The upper Rio Hondo Basin occupies a drainage area of 585 square miles in south-central New Mexico and comprises three general hydrogeologic terranes: the higher elevation “Mountain Block,” the “Central Basin” piedmont area, and the lower elevation “Hondo Slope.” As many as 12 hydrostratigraphic units serve as aquifers locally and form a continuous aquifer on the regional scale. Streams and aquifers in the basin are closely interconnected, with numerous gaining and losing stream reaches across the study area. In general, the aquifers are characterized by low storage capacity and respond to short-term and long-term variations in recharge with marked water-level fluctuations on short (days to months) and long (decadal) time scales. Droughts and local groundwater withdrawals have caused marked water-table declines in some areas, whereas periodically heavy monsoons and snowmelt events have rapidly recharged aquifers in some areas. A regional-scale conceptual water budget was developed for the study area in order to gain a basic understanding of the magnitude of the various components of input, output, and change in storage. The primary input is watershed yield from the Mountain Block terrane, supplying about 38,200 to 42,300 acre-feet per year (acre-ft/yr) to the basin, as estimated by comparing the residual of precipitation and evapotranspiration with local streamgage data. Streamflow from the basin averaged about 21,200 acre-ft/yr, and groundwater output left the basin at an estimated 2,300 to 5,700 acre-ft/yr. The other major output (about 13,500 acre-ft/yr) was by public water supply, private water supply, livestock, commercial and industrial uses, and the Bonito Pipeline. The residual in the water budget, the difference between the totals of the input and output terms or the potential change in storage, ranged from -2,200 acre-ft/yr to +5,300 acre-ft/yr. There is a high degree of variability in precipitation and consequently in the water supply; small

    Full Text Available Mudanças recentes vêm afetando as fronteiras de gênero: masculinidade e feminilidade mostram, em muitas situações, delimitações tênues. Porém, muitos ideais tradicionais de gênero persistem no subconsciente do indivíduo (Goldenberg, 2000. A identidade masculina é construída a partir da negação - negando atributos relacionados à mulher, à criança ou ao homossexual - e aqueles que se consideram fora do padrão dominante de masculinidade ainda demonstram medo de serem vistos como homossexuais (Badinter, 1993, e outros. O consumo de beleza está associado ao desejo de promover um aumento da atratividade física e a obtenção dos benefícios sociais correspondentes (Bloch e Richins, 1992. Como a atratividade física é considerada um elemento central da feminilidade, o consumo de práticas de beleza costuma ser maior entre as mulheres. A identidade de gênero masculina está associada a menor preocupação com a aparência, assim, os homens estão menos inclinados a adotarem práticas de beleza. Neste contexto, como pesquisar o tema beleza entre os homens? O objetivo deste estudo exploratório foi contribuir para uma melhor compreensão sobre o consumidor masculino de produtos e serviços de beleza, refletindo sobre padrões estéticos e práticas relacionadas à beleza masculina. Os relatos foram obtidos através de entrevistas em profundidade, usando também técnica projetiva, com dez jovens homens de classe econômica alta no Rio de Janeiro. Diversos aspectos das práticas de beleza são manipulados pelos entrevistados na caracterização de papéis sociais e na construção das identidades de gênero. Poucas foram as práticas de beleza identificadas como permitidas para o gênero masculino. Eles vêem a beleza como facilitadora das relações sociais e amorosas, mas sucesso profissional e inteligência ainda parecem mais importantes. Homem não precisa ser bonito.

    , more attention is now being given to traits related to health (resistance to EST, mastitis or parasitic diseases). Some studies conducted in New Zealand and Australia showed that nematode resistance is genetically controlled with high heritabilities and quite low genetic correlations with production traits. In this sense, some studies showed that it is possible to decrease the number of parasites in the framework of a traditional breeding programme. However, in most situations, this trait is not extensively recorded due to the high cost of individual recording. Therefore, it would be useful to implement breeding strategies based on the knowledge of the genes involved in this trait expression. Traditionally, two approaches are available to locate a gene: i) genome scan; ii) candidate gene approach. The candidate gene approach attempts to link general resistance to some particular genes. To date, genetic resistance against parasites is considered to be linked with the MHC and IgE genes. Furthermore, several gene detection studies based on the genome scan approach for this trait are currently being carried out on both crossed experimental populations (fat x lean Blackface lines and Sarda x Lacaune) and pure breeds (Churra). The preliminary results seem promising as to the use of marker assisted or genotype assisted selection for this trait, which is difficult and expensive to measure on a population scale.

    Full Text Available Abstract – IT La complessa vicenda del “baratto”, ideata e attuata da Eugenio Barba e l’Odin Teatret a partire dal 1973-74, è una delle più affascinanti imprese appartenenti alla storia del Nuovo Teatro del Novecento. Il saggio ricostruisce il più oggettivamente possibile la permanenza dell’Odin Teatret in Sardegna, tra il 1974 e il 1975, durante la quale le tante comunità sarde risposero spontaneamente alla proposta dell’Odin, "barattando" il proprio patrimonio di canti, balli e pratiche tradizionali. Nato nella città di Cagliari, l’autore ha potuto spesso cogliere nelle testimonianze di intellettuali e artisti isolani l’eco di quella avventura; una traccia viva, quando non proprio un modello mitico, per più di una generazione di operatori culturali tuttora attivi in Sardegna. Da qui il desiderio di ricucire il filo della memoria, nell’idea di restituire quanto più possibile anche una sottile zona del rimosso, osservando con attenzione le date di questa vicenda e alcune testimonianze ad esse correlate. In particolare, secondo l’autore, la così tanto celebrata fase avvenuta a Carpignano Salentino da maggio a ottobre del 1974, a cui si attribuisce convenzionalmente, da un punto di vista storico, la nascita del baratto, in realtà ha teso a oscurare un precedente assai rilevante, legato all’incursione in terra sarda di Barba e compagni, tra Campidano e Barbagia, avvenuta nel mese di gennaio dello stesso anno. Abstract – EN The complex history of the 'baratto', which was conceived and performed by Eugenio Barba and the Odin Teatret from 1973-74, is one of the most challenging and fascinating projects in the history of XX century theatre. The purpose of the present essay is to retrace, as objectively as possible, Odin's permanence in Sardinia between 1974 and 1975, a period during which many local communities gave a positive feedback to Barba's project by 'bartering' traditional songs, dance and rituals. Born in

    Particle diffusion in a cohesionless granular bed, hydraulically fully rough, subjected to a steady-uniform turbulent open-channel flow is investigated. Experiments were carried out under conditions of weak bedload transport in a 12.5 m long and 40.5 cm wide glass-sided flume recirculating water and sediment through independent circuits at the Laboratory of Hydraulics and Environment of Instituto Superior Técnico, Lisbon. The flume bed was divided in two reaches: a fixed reach comprising 1.5 m of large boulders, followed by 3.0 m of smooth bottom (PVC) and 2.5 m of one layer glued 5.0 mm diameter spherical glass beads; a mobile reach 4.0 m long and 2.5 cm deep filled with 5.0 mm diameter glass packed beads. Particle velocities were obtained introducing 5.0 mm diameter white-coated beads in the flow. Particle motion was registered from above using a high-speed camera AVT Bonito CL-400 with resolution set to 2320 x 1000 px2and frame rate of 170 fps. The field of view recorded was 77.0 cm long and 38.0 cm wide, covering almost all the width of the flume. Image processing allowed detecting and locating the centre of mass of the particles with sub-pixel accuracy. Particle trajectories were reconstructed by tracking the beads in the images; particle velocities were obtained as bead displacement over time interval between two consecutive frames (1/170 s). The computation of lagrangian statistics of particle velocities for a Shields parameter θ=0.014, Froude number Fr=0.756, boundary Reynolds number Re*=182.9 and run duration of 20 min (during which 1218 particle trajectories were collected) provided information about particle diffusion within the local and intermediate range of temporal and space scales. Mean particle velocities, second, third and fourth order moments were obtained for both longitudinal and transverse velocity components. A relatively large ballistic range, approximately two particle diameters, was observed, mainly due to the simple bed topography of

However, in view of a potential clinic application of this finding, our exosome-based immunization strategy was faced with possible technical difficulties including industrial manufacturing, cost of production, and storage. To overcome these hurdles, we designed an as yet unproven exosome-based immunization strategy relying on delivery by intramuscular inoculation of a DNA vector expressing Nefmut fused with HPV E7. In this way, we predicted that the expression of the Nefmut/E7 vector in muscle cells would result in a continuous source of endogenous (ie, produced by the inoculated host engineered exosomes able to induce an E7-specific immune response. To assess this hypothesis, we first demonstrated that the injection of a Nefmut/green fluorescent protein-expressing vector led to the release of fluorescent exosomes, as detected in plasma of inoculated mice. Then, we observed that mice inoculated intramuscularly with a vector expressing Nefmut/E7 developed a CD8+ T-cell immune response against both Nef and E7. Conversely, no CD8+ T-cell responses were detected upon injection of vectors expressing either the wild-type Nef isoform of E7 alone, most likely a consequence of their inefficient exosome incorporation.

In questa indagine verrà esaminata non tanto la commutazione di codice italiano/inglese, italiano/spagnolo, ecc. quanto piuttosto l’inclusione della varietà dialettale sarda fra le lingue che gli immigrati adoperano nelle diverse interazioni sociali con i parlanti nativi allo scopo di “accelerare l’assimilazione nel gruppo dominante” (Loi Corvetto 2000: 42.Il corpus consiste di circa trenta ore di registrazione di parlato spontaneo. Si è ritenuta infatti prioritaria la possibilità di osservare e esaminare la produzione linguistica di parlanti che interagissero in contesti situazionali i più naturali possibili, pertanto le tecniche adoperate nella raccolta del corpus rispondono principalmente all’ esigenza di poter ottenere dati relativi al parlato naturale, non sorvegliato, di cui è possibile disporre solamente se i parlanti non sanno di essere registrati.Da un punto di vista metodologico, si tratterà in primo luogo di individuare: (a le caratteristiche morfologiche e sintattiche del discorso bilingue italiano/campidanese da parte degli apprendenti italiano L2, vale a dire quali categorie

    The development and progress of antidiabetic drugs (e.g., insulin preparations and hypoglycemic drugs) are retrospectively investigated in Japan. Their influences on the treatment of diabetes mellitus (DM) and its epidemiological aspects are also discussed. 1) Insulin preparations: Insulin was introduced for DM therapy in 1925, two or three years after its discovery in Canada. The preparations were raw extracts of bovine or porcine pancreas. These did not prevail widely in Japan because of the low incidence of DM before World Wan II. After the war, a shortage of mammalian materials compelled the use of fish pancreatic tissues such as bonito and/or tuna for insulin production. Insulin infection, so-called regular insulin, was first promoted in the 6th "Pharmacopoeia Japonica" (JP6) in 1951 and has been maintained to the present edition (JP14, 2001). Although depot-type insulin preparations were developed in the USA and Europe during the war, the introduction of those preparations to Japan was delayed until 1951, when Protamine zinc insulin appeared. Globin zinc insulin and Isophane insulin were introduced for clinical use in 1952 and 1955, respectively. These were also adopted for JP7 (1961). Biphasic-type insulin, which has a rapid onset and long duration of activity, appeared in 1965. Purified preparations from bovine or porcine sources have been available since 1980, which might be a strong reason for the decrease in insulin allergy. Insulin from animal origin has been supplied for almost 60 years since its discovery. Amino acid sequences of insulins from various species of animals were determined by the pioneering studies of Sanger and his associates. Human insulin, which differs from porcine insulin by only one amino acid, was produced by Novo researchers in 1982 using a semi-synthetic method. Then the Lilly group soon succeeded in obtaining human insulin by recombinant DNA technology in the same year. Both products were introduced to Japan in 1985, and the

    We analyze paths of sediment particles on cohesionless granular bet subjected to a turbulent open-channel flow. The key objective is to provide further insights on particle dispersion including resting times. Hence, we focus on the spatial and temporal scale identified by Nikora et al. (2002) as the global range, defined as the particle path composed of many intermediate range paths, i.e with several "starts" and "stops". This requires the calculation of the probability distribution functions of particle travel distances and of rest periods. The experimental work was performed at the Hydraulics Laboratory of IST-UL in a 12.5 m long, 0.405 m wide glass-walled flume recirculating water and sediment through independent circuits. The granular bed was a 4.0 m long and 2.5 cm deep reach filled with 5 mm diameter glass beads packed (with some vibration) to a void fraction of 0.356, typical of random packing. Upstream the mobile bed reach the bed was composed of glued particles to ensure the development of a boundary layer with the same roughness. Laboratory tests were run under conditions of weak beadload transport with Shields parameter (θ) in the range 0.007 to 0.030, Froude numbers (Fr) between 0.630 and 0.950 and boundary Reynolds number (Re_ast) in the range 130 to 300. White-coated particles with 5.0 mm diameter were introduced in the flow 3 m upstream the mobile bed reach. Particle motion was registered from above using a high-speed camera AVT Bonito CL-400 with resolution set to 2320 × 1000 px2 and frame rate of 170 fps. The field of view recorded was 77.0 cm long and 38.0 cm wide, covering almost all the width of the flume. The maximum duration of the runs was 20 min, during which more than 500 particle paths, including resting times, were registered. The video footage was subjected to a PTV (Particle Tracking Velocimetry) developed for the problem at hand. The algorithm includes the application of Gaussian filters and thresholding operations to identify the

    Ribeirão Bonito, which forms part of the transect making up the geosystem of Teodoro Sampaio, and Pontal do Paranapanema. Human intervention can be seen as the main agent in promoting these exchanges between environments due to the transit of people between subgeosystems and the interrelationship with other municipalities encouraging the spread of the disease. The only municipalities to be among those with a high incidence of AVL are Araçatuba and Presidente Prudente, although the number of cases is growing and becoming more concentrated. The state presents a circumscribed hub of AVL cases in the region of Campinas and Piracicaba, and another in Pontal do Paranapanema. This interaction borders on Mato Grosso do Sul, giving rise to the main circuit AVL instances of the Southeast. ACL has a hub at Itapetininga, which is next to Vale do Paraiba Paulista, also leading to interactions across the border with the state of Rio de Janeiro and its principal circumscribed centres of transmission of ACL. This will be Brazil’s next ACL production circuit. It was possible to identify areas in the state of São Paulo particularly vulnerable to Leishmaniasis with particular distributions for each of the two types of the disease, sometimes existing together. Outbreaks of canine VL do not depend on distribution rules on a small scale, although the effect of many outbreaks together clarifies a spatial pattern, as seen in the state of São Paulo. Patterns of transmission of Leishmaniasis are established in the state of São Paulo and the data analyzed helps to verify these patterns. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Tabela normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso

    Full Text Available O presente trabalho teve como objetivo avaliar o efeito protetor da acetamida nas intoxicações experimentais por Pseudocalymma elegans em ovinos, caprinos e coelhos, com a finalidade de comprovar indiretamente que o monofluoroacetato (MF é responsável pelos sinais clínicos e a morte dos animais que ingerem essa planta. Foram realizados experimentos para determinar a dose letal da planta coletada em Rio Bonito, RJ, em diferentes épocas do ano para ovinos e caprinos e ajustar a dose de acetamida a ser administrada. - No primeiro experimento, dois ovinos e dois caprinos receberam 1,0g/kg de P. elegans fresca e um animal de cada espécie foi tratado previamente com 2,0g/kg de acetamida. Nenhum animal apresentou alterações clínicas ou morreu. Ao que tudo indica a planta poderia estar menos tóxica, já que foi coletada no fim da estação das águas. - No segundo experimento, dois ovinos e dois caprinos receberam 0,67 e 1,0g/kg da planta dessecada, após tratamento prévio, com 2,0 e 3,0g/kg de acetamida, respectivamente. Todos os animais morreram, pois administramos doses muito altas de P. elegans. - No terceiro experimento, dois ovinos e dois caprinos receberam 0,333g/kg de P. elegans dessecada, após administração prévia de 2,0 g/kg de acetamida. Uma semana depois, o protocolo acima foi repetido, porém sem o antídoto. Nos experimentos com coelhos, foram administradas doses de 0,5 e 1,0g/kg de elegans dessecada após a administração de 3,0g/kg de acetamida. Sete dias depois, repetiu-se o protocolo, com exceção da administração de acetamida. Esta, quando administrada previamente, evitou o aparecimento dos sinais clínicos e a morte dos ovinos, caprinos e coelhos, já os animais não tratados com acetamida apresentaram sintomatologia e morreram. Clinicamente, os ovinos e caprinos manifestaram taquicardia, jugulares ingurgitadas, pulso venoso positivo, decúbito esternal e tremores musculares. Na "fase dramática", os animais ca

    “El gran artista que pintó La Cena en la pared del refectorio de un convento de Milán dejaba correr la vida de sus pinceles; en ese cuadro, fíjate bien, casi todos hablan pero las manos son más expresivas cuando hay cosas importantes que decir; trataba se de saber quién se atrevería a vender al Maestro; ¿me estás acompañando? Es la Santa Cena, ¿la viste bien?” Explicó el fraile. Antonio confirmó moviendo la cabeza y dijo: ¿Me la prestais? Oyéronle la voz después de dos semanas! El fraile había curado al mulato. Por la noche el papá le corregía los diseños y una vez le preguntó qué era lo más bonito que había visto y al responderle que un santo echando candela por las manos, le explicó que eran los estigmas de San Francisco y que le hiciera de ellos un buen diseño. Desde entonces para Antonio las manos fueron su obsesión.

    Manuella estimulaba para compartir su oficio y lo llevaba a comer en las tabernas, visitar amigos, atender convites a bailes y serenatas. Para festejar la asignación de un contrato Manuella llevó a su casa, vistió la mejor ropa y se entregó a la prestidigitación arrojando monedas de oro al amplio regazo de María, su esposa, que no sabía ser alegre ni entendió el juego. Manuel atrapó una moneda de oro que caía, lanzó un improperio y se fue con Antonio a beber en otras partes. Bien bebido y estimulado por canciones eróticas dijo a Antonio: he hecho obras pero no he sido sino rematador; quiero que seas más que tallador y contratista, olvídate de la oficina y quédate con Xavier de Brito que tiene mucho que enseñarte.

    A la mañana siguiente entró Fray Felipe con el maestro de Brito traído para las tallas del altar mayor y le había informado que Antonio trataba de ser un buen tallista; lo invitó a su casa, hablaron largamente, le dio elementos para un diseño y se fue a beber vino; al volver miró el diseño y le dijo: No sabes

    Full Text Available O processo de Reforma Agrária constitui-se em um agente transformador e ao mesmo tempo criador de espaços diferenciados, já que está associado às formas de apropriação e exploração da superfície terrestre. Dessa forma, os assentamentos rurais, produtos desse processo de transformação, tornam-se objetos de estudos da Geografia. Por causa das rápidas e inevitáveis transformações no uso da terra ocorridas nos assentamentos, que conduzem à fragmentação e até à supressão da vegetação natural, o objetivo da presente pesquisa consistiu em identificar e caracterizar ambientalmente os fragmentos florestais de ocorrência natural em áreas de assentamentos rurais, mais especificamente no Projeto de Assentamento Ireno Alves dos Santos, situado nos Municípios de Rio Bonito do Iguaçu e Nova Laranjeiras - PR, no período de 1996 a 2002; tais fragmentos são remanescentes da Floresta Ombrófila Mista e Floresta Estacional Semidecidual, cuja manutenção tornou-se bastante delicada, uma vez que deixaram de fazer parte de uma área florestada maior e passaram a ficar “ilhadas”, cercadas por áreas agrícolas, desencadeando diversas alterações ambientais (efeitos de borda. O objetivo proposto foi atendido mediante a aplicação de metodologia para a identificação e manejo de fragmentos de áreas naturais proposta por PIRES et al. (1998. As tarefas necessárias ao desenvolvimento da metodologia foram operacionalizadas a partir de técnicas de Geoprocessamento e Sensoriamento Remoto, que permitiram a elaboração de mapas temáticos digitais representando a evolução da fragmentação florestal; ao final, foi gerado o mapasíntese da espacialização dos fragmentos florestais. Algumas hipóteses procuraram explicar as causas para as alterações verificadas ao longo dos anos na área do assentamento, tais como: a instalação da empresa madeireira proprietária da área; a construção da Usina Hidrelétrica de Salto Santiago; a

     » pour publics aisés et branchés. Au final, les paysages qui pouvaient servir d’image-support à un tourisme innovant et différencié de l’offre touristique générale sont plutôt cantonnées dans un registre conservateur et classique. Comme monnaie d’échange, la mise en paysage réalisée par l’Estrada Real se traduit par une imagerie paysagère incomplète et impose, peu à peu, ses codes uniformisant de lecture et de valorisation.Bem além das idéias preconcebidas e bastante contestáveis, as paisagens do Brasil revelam, a quem se dispõe para tanto, uma viagem diversificada em meio à natureza e cultura num país-continente. No entanto, exceto no caso de um consumo visual dos lugares nobres, a valorização das paisagens no âmbito da atividade turística ainda é embrionária. Enquanto itinerário turístico que percorre os estados de São Paulo, Rio de Janeiro e Minas Gerais ao longo de aproximadamente 1200 km, a Estrada Real tem a ambição de impor-se como o produto de ponta do turismo rural e cultural do Brasil. Iniciado em 1999, com forte apoio de publicidade e marketing, este itinerário implementa um realce paisagístico dos territórios atravessados por meio de diversos suportes, cuja mídia principal é uma luxuosa iconografia (livros bonitos, revistas em papel brilhante, cofrinhos de cartões postais. Neste contexto, focalizamos nosso interesse sobre o modo como foi tratada a questão da paisagem nesta iconografia. Analisamos, portanto, a produção de uma imagética, na base de um corpus limitado aos cartões postais e revistas editadas pelo Instituto Estrada Real, procurando nelas a identificação e distinção das naturezas das paisagens exibidas, bem como os valores e qualidades que lhes foram atribuídos por meio dessa promoção. Causa estranheza encontrar uma homogeneidade paisagística expressa pelas diferentes imagens produzidas e quase ausência das paisagens rurais, trama fundamental desses territórios.

É preciso encarar esta questão sob uma visão que busque privilegiar o seu aproveitamento, visando a otimização dos recursos e, ao mesmo tempo, buscando minimizar as conseqüências da permanência destes resíduos no ambiente. Assim sendo, o objetivo do presente estudo é quantificar os impactos ambientais causados pelo mau tratamento dado ao lixo urbano e como estes impactos podem contribuir para a degradação não só do ambiente, mas também em todo o sistema onde está inserido. Esta tese de Doutorado pretende estabelecer a contaminação do solo e das águas superficiais e subterrâneas condicionada pelos Lixões de Bangu e Santa Cruz situados no Município do Rio de Janeiro. Autor: Mario Jorge Gesteira Fonseca Orientador: Julio Cezar Mendes Título: Pegmatitos da parte centro-leste do estado do Rio de Janeiro e seu contexto tectônico - 229 p. Resumo O estudo dos pegmatitos da parte centro-leste do território do estado do Rio de Janeiro, a leste da baía de Guanabara, conduziram a uma separação em três Distritos Pegmatíticos: o Distrito Niterói - Rio Bonito, a sudoeste da área estudada, o Distrito de Casimiro de Abreu-Sana, a leste-sudeste, e o Distrito de Cantagalo, a nordeste. Este último distrito tem um condicionamento tectono-magmático-metamórfico bem distinto dos dois anteriores. Mais de 60% dos corpos pegmatíticos estão ligados à anatexia. Eles se classificam como pegmatitos simples ou de grande profundidade, de paragênese e mineralogia bastante simplificadas. Os pegmatitos restantes estão associados a granitóides brasilianos, desde os corpos pré-colisionais até os granitóides pós-tectônicos. Os pegmatitos provenientes desses corpos
