Estimativa amostral objetiva de área plantada regional, apoiada em imagens de sensoriamento remoto

O objetivo deste trabalho foi desenvolver e avaliar um método para estimar a área plantada de soja em escala regional e calcular o erro estatístico associado à estimação. O método (Geosafras), que associa técnicas de amostragem estatística com características das imagens obtidas por sensoriamento remoto orbital, foi aplicado para obter estimativa amostral objetiva da área cultivada com soja, na safra de 2005/2006, no Estado do Rio Grande do Sul. Os municípios produtores de soja, no RS, foram distribuídos em dez estratos, com base em dados pré‑existentes de área cultivada com a cultura. O número de municípios selecionados, em cada estrato, seguiu a regra de alocação de Neyman. Em cada município selecionado, foram aleatorizados pontos correspondentes aos pixels das imagens, classificados como "soja" ou "não soja" após visita a campo. A partir dos dados de 3.000 pontos distribuídos nos 30 municípios selecionados, nos dez estratos, foi estimada a área cultivada com soja no RS, que totalizou 4.069.887 ha, com coeficiente de variação (CV) de 3,4%. Esta estimativa foi consistente com os dados oficiais. O método amostral objetivo estratificado, auxiliado por sensoriamento remoto, permite estimar a área cultivada com soja no Rio Grande do Sul e é capaz de quantificar o erro associado à estimativa realizada.

Real-time MR imaging of myocardial regional function using strain-encoding (SENC) with tissue through-plane motion tracking.

PURPOSE: To implement real-time myocardial strain-encoding (SENC) imaging in combination with tracking the tissue displacement in the through-plane direction. MATERIALS AND METHODS: SENC imaging was combined with the slice-following technique by implementing three-dimensional (3D) selective excitation. Certain adjustments were implemented to reduce scan time to one heartbeat. A total of 10 volunteers and five pigs were scanned on a 3T MRI scanner. Spatial modulation of magnetization (SPAMM)-tagged images were acquired on planes orthogonal to the SENC planes for comparison. Myocardial infarction (MI) was induced in two pigs and the resulting SENC images were compared to standard delayed-enhancement (DE) images. RESULTS: The strain values computed from SENC imaging with slice-following showed significant difference from those acquired without slice-following, especially during systole (P < 0.01). The strain curves computed from the SENC images with and without slice-following were similar to those computed from the orthogonal SPAMM images, with and without, respectively, tracking the tag line displacement in the strain direction. The resulting SENC images showed good agreement with the DE images in identifying MI in infarcted pigs. CONCLUSION: Correction of through-plane motion in real-time cardiac functional imaging is feasible using slice-following. The strain measurements are more accurate than conventional SENC measurements in humans and animals, as validated with conventional MRI tagging.

SICA2 : la experiencia de integración CRIS/RI en el ámbito regional de Andalucía

El proyecto SICA2, presentado por Beatriz Barros y Miguel Ángel Aguirre, de la Consejería de Economía, Innovación y Ciencia de la Junta de Andalucía, supone una innovadora extensión del concepto de CRIS universitario a un ámbito regional para el conjunto de las universidades andaluzas. El sistema de recogida y validación de la información científica en tiempo real se basa en una primera fase SICA que organiza la investigación en unidades mínimas o 'Grupos PAIDI' y que ya implementó el estándar CVN para las nueve universidades andaluzas que forman parte del proyecto. Esta segunda fase de integración tiene además prevista su prolongación en el repositorio institucional Reposit-AN de ámbito igualmente regional que se alimentará de los metadatos procedentes del sistema CRIS de la Junta de Andalucía y se presentará oficialmente a final de año.

Micromeasurement of total and regional CO2 productions in the one-day-old chick embryo.

A conductometric micromethod combined with image analysis system has been developed allowing to determine the CO2 production within 'two-dimensional' tissues, i.e., flat and thin cell layers or epithelial sheets. The preparation was mounted into an airtight chamber separated in two compartments by a thin silicone membrane permeable to gases. The lower compartment contained the nutritive medium and the preparation. The upper compartment and a conductivity measuring capillary connected in series were perfused with a solution of Ba(OH)2. The CO2 produced by the tissue precipitated as BaCO3 and the resulting decrease of electrical conductivity was linearly related to the total CO2 production. In addition, the pattern of CO2 production was directly observable as the BaCO3 crystals formed upon the silicone membrane over the regions which produced CO2. The spatial distribution of the crystals was quantified by video image processing and the regional CO2 production evaluated with a spatial resolution of 100 microns. This new microtechnique was originally developed to study the CO2 production in the early chick blastoderm which is a disc 1-5 cells thick. At the stage of young neurula the CO2 production was found to be 235 +/- 37 nmol.h-1 (mean +/- SD; n = 10) per blastoderm and large variations of local CO2 production were detected from one region to another (from 0.6 to 6.5 nmol.h-1.mm-2). These results indicate a high metabolic and functional differentiation of cells within the blastoderm. The possible applications and improvements of such a microtechnique are discussed.

Local and Regional Scale Determinants of Biodiversity Patterns in Boreal Agricultural Landscapes

This thesis examines the local and regional scale determinants of biodiversity patterns using existing species and environmental data. The research focuses on agricultural environments that have experienced rapid declines of biodiversity during past decades. Existing digital databases provide vast opportunities for habitat mapping, predictive mapping of species occurrences and richness and understanding the speciesenvironment relationships. The applicability of these databases depends on the required accuracy and quality of the data needed to answer the landscape ecological and biogeographical questions in hand. Patterns of biodiversity arise from confounded effects of different factors, such as climate, land cover and geographical location. Complementary statistical approaches that can show the relative effects of different factors are needed in biodiversity analyses in addition to classical multivariate models. Better understanding of the key factors underlying the variation in diversity requires the analyses of multiple taxonomic groups from different perspectives, such as richness, occurrence, threat status and population trends. The geographical coincidence of species richness of different taxonomic groups can be rather limited. This implies that multiple geographical regions should be taken into account in order to preserve various groups of species. Boreal agricultural biodiversity and in particular, distribution and richness of threatened species is strongly associated with various grasslands. Further, heterogeneous agricultural landscapes characterized by moderate field size, forest patches and non-crop agricultural habitats enhance the biodiversity of rural environments. From the landscape ecological perspective, the major threats to Finnish agricultural biodiversity are the decline of connected grassland habitat networks, and general homogenization of landscape structure resulting from both intensification and marginalization of agriculture. The maintenance of key habitats, such as meadows and pastures is an essential task in conservation of agricultural biodiversity. Furthermore, a larger landscape context should be incorporated in conservation planning and decision making processes in order to respond to the needs of different species and to maintain heterogeneous rural landscapes and viable agricultural diversity in the future.

Simultaneous measurement of regional cerebral blood flow by perfusion CT and stable xenon CT: a validation study.

BACKGROUND AND PURPOSE: Knowledge of cerebral blood flow (CBF) alterations in cases of acute stroke could be valuable in the early management of these cases. Among imaging techniques affording evaluation of cerebral perfusion, perfusion CT studies involve sequential acquisition of cerebral CT sections obtained in an axial mode during the IV administration of iodinated contrast material. They are thus very easy to perform in emergency settings. Perfusion CT values of CBF have proved to be accurate in animals, and perfusion CT affords plausible values in humans. The purpose of this study was to validate perfusion CT studies of CBF by comparison with the results provided by stable xenon CT, which have been reported to be accurate, and to evaluate acquisition and processing modalities of CT data, notably the possible deconvolution methods and the selection of the reference artery. METHODS: Twelve stable xenon CT and perfusion CT cerebral examinations were performed within an interval of a few minutes in patients with various cerebrovascular diseases. CBF maps were obtained from perfusion CT data by deconvolution using singular value decomposition and least mean square methods. The CBF were compared with the stable xenon CT results in multiple regions of interest through linear regression analysis and bilateral t tests for matched variables. RESULTS: Linear regression analysis showed good correlation between perfusion CT and stable xenon CT CBF values (singular value decomposition method: R(2) = 0.79, slope = 0.87; least mean square method: R(2) = 0.67, slope = 0.83). Bilateral t tests for matched variables did not identify a significant difference between the two imaging methods (P >.1). Both deconvolution methods were equivalent (P >.1). The choice of the reference artery is a major concern and has a strong influence on the final perfusion CT CBF map. CONCLUSION: Perfusion CT studies of CBF achieved with adequate acquisition parameters and processing lead to accurate and reliable results.

The effects of regional educational policies on school failure in Spain

This paper presents a regional analysis of the effects of educational policies implemented in Spain between 1992 and 2003, focusing specifically on school failure rates. We consider the impact of expenditure per pupil, class size, and pupil-teacher ratio on dropout rates at the end of compulsory education and on the proportion of early school-leavers in the 18-24 year age group. Our results indicate that higher levels of educational expenditure per pupil and lower class sizes and pupil-teacher ratios reduce rates of dropout and early school-leaving (although class-size is not always significant). However, the magnitude of the effects of these variables is small at the average level.

Green Field fluteboard factory infrastructure requirements in Russia

Russian corrugated board market is rapidly developing. Owing to that Russia becomes more and more attractive to the companies ¿ world leaders in corrugated board production. Thus, in order to strengthen or even to maintain its market position the firm should uninterruptedly develop improving volume and quality of the products. At the same time operations in the Russian market are commonlyassociated with various types of risks which should be avoided. Unfortunately, the information of the Russian corrugated board market is not systematized yet there is almost no theoretical background in this areaand, therefore, the thesis is mainly based on the practical experience of the managers of Stora Enso. The goal of the paper is to define and describe the main particularities of Russian corrugated board market which are lying in different areas and to concentrate on the difficultieswith which a corrugated board factory may face while functioning in the Russian market. The contribution of the thesis consists of forming general requirements and principles while establishing a corrugated boardproduction facility and maintaining its operations in order to avoid risks, to save time and financial resources and as a result to operate in the Russian market obtaining higher profits.

Regional Innovation Policy: Effect on SMEs in Five EU-Regions

Valtaosa eurooppalaisista yrityksistä on pk-yrityksiä, mutta tästä huolimatta seudullisen innovaatiopolitiikan vaikutusta juuri pk-yrityksiin on tutkittu melko vähän. Tämän tutkimuksen tarkoituksena on luoda yleiskuva pk-yritysten näkemykseen oman seutunsa innovaatiopolitiikasta viidellä EU:n alueella sijaitsevalla seudulla. Kirjallisuuden perusteella rakennettiin seudullista innovaatiopolitiikkaa kuvaava kysely, johon joukko pk-yrityksiä viideltä seudulta vastasi. Kyselyn tulokset kuvailtiin graafisesti, minkä lisäksi etsittiin vastauksiin vaikuttaneita tekijöitä ja yhteyksiä yritysten vastausten välillä. Tutkimus oli luonteeltaan lähinnä kvantitatiivinen. Tutkimus osoittaa, että seudullisessainnovaatiopolitiikassa on vielä paljon kehitettävää, jotta se tavoittaisi kattavasti pk-yritykset. Pk-yritysten tietoisuutta tulisi lisätä, sillä nämä eivät yleisesti ottaen näytä pitävän seudullista innovaatiopolitiikkaa menetykseen vaikuttavana tekijänä tai siihen liittyviä yhteistyömahdollisuuksia tärkeinä omalle toiminnalleen. Erot innovaatiotoiminnan seudullisessa roolissa tulivat esiin tuloksissa. Yritysten vastauksia selittäviä tekijöitä löydettiin, samoin yhteyksiä vastausten välillä, mutta varsinaisten johtopäätösten tekeminen edellyttänee laajempaa tutkimusta

When supply travels far beyond demand: Causes of oversupply in Spain’s transport infrastructure

Spain’s transport infrastructure policy has become a paradigmatic case of oversupply and of mismatch with demand. The massive expansion of the country’s transport infrastructure over the last decade has not been a response to demand bottlenecks or previously identified needs. For this reason, the intensity of use today on all interurban modes of transport in Spain falls well below that of other EU countries. This paper analyzes the institutional and regulatory factors that have permitted this policy, allowing us to draw lessons from the Spanish case that should help other countries avoid the pitfalls and shortcomings of Spanish policy.
