| We present a detailed 3-D P-wave velocity model obtained by first-arrival travel-time tomography with seismic refraction data in the segment boundary of the Sumatra subduction zone across Simeulue Island, and an image of the top of the subducted oceanic crust extracted from depth-migrated multi-channel seismic reflection profiles. We have picked P-wave first arrivals of the air-gun source seismic data recorded by local networks of ocean-bottom seismometers, and inverted the travel-times for a 3-D velocity model of the subduction zone. This velocity model shows an anomalous zone of intermediate velocities between those of oceanic crust and mantle that is associated with raised topography on the top of the oceanic crust. We interpret this feature as a... |

| Nos últimos anos, a avicultura brasileira tem apresentado grande crescimento na produção e a criação de perus acompanha - de certa forma - este desempenho. Como o frango de corte, grande parte da produção de carne de peru é exportada. Todavia, o frango de corte tem o consumo no mercado interno bastante consolidado, o que já não ocorre com o consumo de derivados de peru, que se apresenta bastante baixo, apesar do crescimento nos últimos cinco anos. A presente pesquisa analisou a estratégia de segmentação do mercado dos produtos à base de carne de peru, o comportamento de compra baseado nos preços desses produtos no varejo vis-à-vis os dos derivados de frango e as possíveis causas do baixo consumo per capita brasileiro. A pesquisa foi realizada em três... |

| An automated signal-based method was developed in order to analyse the seafloor backscatter data logged by calibrated multibeam echosounder. The processing consists first in the clustering of each survey sub-area into a small number of homogeneous sediment types, based on the backscatter average level at one or several incidence angles. Second, it uses their local average angular response to extract discriminant descriptors, obtained by fitting the field data to the Generic Seafloor Acoustic Backscatter parametric model. Third, the descriptors are used for seafloor type classification. The method was tested on the multi-year data recorded by a calibrated 90-kHz Simrad ME70 multibeam sonar operated in the Bay of Biscay, France and Celtic Sea, Ireland. It... |

| The objective of the present study is to describe the preferences of younger, more educated and higher income Greek consumers for "quality" olive oil brands - quality being defined as a bundle of extrinsic quality cues such as quality assurance labels, health-related information, country-of-origin indication, bottling material and price. The aim of the research is, with the implementation of a conjoint analysis task, to describe and analyze consumer preferences using a random, stratified, sample of urban consumers. The extrinsic quality attributes of olive oil, strongly linked to a previous qualitative, Means-end Chains (MEC) analysis survey, is used as starting points for the development of conjoint profiles. Special emphasis is given to the development... |

| Pork is a source of nutrients essential for the human body but still it is regarded by consumers as a non-healthy product. The main objective of the study was to analyse consumption patterns concerning pork products and to define alternative target markets in bigger Hungarian towns. In the course of the research, 494 people, representative of the base population, were questioned. According to the results obtained, the consumers’ opinion and the already formed image are less favourable regarding pork than poultry in almost all respects. Respondents regarded pork as an out-of-date, slightly boring and aging product. The applied cluster analysis identified five different consumer segments. Among them, rational young consumers represent the primary target... |

| This issue handles the ability of using segmentation results of sidescan sonar images for long term registration. This study take a part of AUV (Autonomous Underwater Vehicle) navigation problems, particularly to correct the drift of navigation sensors. Principle of images formation with this type of engines and the main properties are first reminded. Some images are shown, which allows us to understand difficulties of this type of data to realise AUV positioning. Then, we decide that segmentation results of sidescan images provide us landscapes on which registration will be able. Segmentation is then explained. It is supervised type on five classes, rocks, ripples, sand, mud and shadow. Using Gabor filters provides classifying parameters and... |

| Nous avons réalisé cette étude dans le but de fournir aux agents d'IFREMER chargés de la surveillance des eaux littorales et en particulier de la flore phytoplanctonnique, un outil permettant d'identifier et de compter les cellules de Dinophysis de façon automatique. La visionique nous semblant être une discipline qui se prêtait à ce type de détection, nous avons réalisé une étude de faisabilité d'un système d'analyse d'il}1age appliqué à la reconnaissance et au comptage de Dinophysis. Le capteur utilisé est une caméra J.V.C Tri C.C.D transmettant trois images (rouge - verte - bleue) à un ordinateur compatible A.T.. Celui ci est équipé d'un ensemble de cartes MATROX de numérisation et traitement d'images et d'un coprossesseur arithmétique. Les applications... |

| Results from a pilot application of Defra’s segmentation model applied to the Farm Business Survey for England are presented. Interviews with 750 FBS co-operators during 2010, using a discursive approach, classified co-operators into one of five segmentation groups: Custodians (14.0%); Lifestyle Choice (7.2%); Pragmatists (53.3%); Modern Family Business (21.1%); Challenged Enterprises (4.4%). On average, Modern Family Businesses operated the largest land area, achieved the greatest farm financial (and agricultural) output, and Farm Business Income (FBI), whilst the Lifestyle Choice segment returned the lowest average FBI. Variation in regional tendencies across the segmentation groups was observed, with variation also noted for forms of business, LFA and... |

| This paper focuses on agro- food chains and agro- food consumer prices in Slovenia considering its European Union (EU) membership. As the Slovenian agro- food markets were distorted prior to the EU accession with some agro- food prices that were greater than comparable EU prices, the empirical results confirm that with the EU membership Slovenian real agro- food consumer prices have largely downward adjusted. Besides policy changes, internalization of retailing and distribution chains by entries of supermarket s and hypermarket s have had impacts on market structures and rationalization of marketing activities. Supermarket s and hypermarket s are taking over a substantial proportion of retail trade in agro- food products with implications on increasing... |

| The Gulf of Aden is a young, obliquely opening, oceanic basin where tectonic structures can easily be followed and correlated from the passive margins to the active mid-oceanic ridge. It is an ideal laboratory for studies of continental lithosphere breakup from rifting to spreading. The northeastern margin of the Gulf of Aden offers the opportunity to study on land the deformation associated with oblique rifting over a wide area encompassing two segments of the passive margin, on either side of the Socotra fracture zone, exhibiting distinct morphologic, stratigraphic, and structural features. The western segment is characterized by an elevated rift shoulder and large grabens filled with thick synrift series, whereas the eastern segment exhibits low... |

| We present in this paper the advantages of the latent class vector model approach in the analysis of preference ratings. We illustrate the practical application of this methodology on the basis of a preference study of smoked salmons in European countries. A set of 30 samples was selected spanning the characteristic variability of cold-smoked salmon available in six European countries (Belgium, Denmark, France, Germany, Italy and the United Kingdom). Consumers from the main countries of consumption (Belgium, France, Italy, Germany and the United Kingdom) were asked to rate the acceptability of each product. A quantitative descriptive analysis with a trained panel and physical and chemical measurements of smoked salmons were also conducted. Using a latent... |

| Increased consumption of vegetables may reduce obesity and the prevalence of cardiac diseases and cancer. Norwegians consume less vegetables than nutrition experts recommend and the per capita consumption is lower than in most European countries. To investigate the causes of low consumption, a two-step approach is used to estimate the demand segmented by nine different household types. In the first step, a probit model is estimated to investigate the decision whether to purchase traditional vegetables, salad vegetables, and industrially processed vegetables. Conditional on purchase, an almost ideal demand model is used to model how much to purchase. The own-price elasticities and total expenditure elasticities are high for traditional and industrially... |
