ITS som stöd för funktionshindrade bilförare : med fokus på förarstöd och säkerhet

Denna rapport presenterar ett examensarbete på C-nivå där uppdragsgivaren har varit Hedemora Anpassning som bygger om och anpassar bilar för människor med olika funktionshinder. Företaget vill i framtiden ha möjlighet att erbjuda sina kunder ITS-tjänster. Målet med arbetet har varit att undersöka hur ITS skulle kunna stödja de funktionshindrade i deras bilkörning. Syftet delades upp i två delsyften, dels kartläggning av vilka tjänster som finns och är under utveckling inom området ITS – förarstöd och säkerhet samt hur de skulle kunna användas/anpassas för funktionshindrade dels att göra en undersökning av vilka behov de funktionshindrade har av ITS. De metoder som använts har varit kvalitativa intervjuer samt litteraturstudier. De senare har använts för att få inblick i ämnet ITS och tjänster som finns eller är under utveckling inom området. Intervjuerna gjordes med personer som endera arbetar med forskning inom ITS eller är verksamma inom området samt med funktionshindrade bilförare. En kartläggning av tjänster har skett och resultatet av intervjuerna pekar på att det finns ett behov av ITS-tjänster för funktionshindrade bilförare. Delvis finns behov av tjänster som redan finns i dag, till exempel navigationssystem. Det finns även behov av andra tjänster som är under utveckling. Gemensamt för dessa tjänster är att de i vissa fall skulle behöva anpassas till de funktionshindrade med röstanpassning eller andra specifika anpassningar.

Expectativas socialmente construídas: fundamentos, formalização e resultados exploratórios

Esta tese é uma discussão crítica, sob a ótica da formação de expectativas, da relação que se interpõe entre ciência econômica, como corpo de conhecimento, e seus agentes. Primeiro, examinamos abordagens relevantes sobre expectativas na análise econômica, indicando suas insuficiências. Argumentamos que a incorporação de expectativa, em qualquer tratamento analítico, deve envolver, principalmente, fundamentos epistêmicos. Segundo, sob a perspectiva da teoria de modernidade reflexiva desenvolvida por Anthony Giddens, buscamos identificar bases plausíveis para uma teoria de expectativa econômica. Concluímos que o processo de formação de expectativa é construção social, a partir da interdependência entre expertos e leigos. Denominamos esta conclusão por hipótese de expectativas socialmente construídas (HESC). Terceiro, propusemos um arcabouço analítico para incorporar a HESC. Basicamente, informação de expectativa se difunde através da mídia e do contato face a face entre agentes. Nova informação não resulta necessariamente em revisão de expectativas, o que vai depender, principalmente, de conhecimento econômico e vizinhança do agente. Por último, um exemplo de aplicação: o modelo-HESC foi submetido a três experimentos macroeconômicos, e seus resultados comparados àqueles obtidos por Mankiw e Reis (2002). A primeira conclusão desta tese é metodológica: expectativas dos agentes em modelos macroeconômicos não são determinadas a partir de equações do próprio modelo. A segunda é normativa: conhecimento e vizinhança são capazes de perpetuar ineficiências decorrentes de erros de expectativas. A terceira está relacionado com economia positiva: as diferenças entre os resultados do modelo de informação-rígida obtidos pelos autores acima e aqueles do modelo-HESC apontam para novas possibilidades explanatórias.

Anthrone and oxanthrone C,O-diglycosides from Picramnia teapensis

Two C,O-diglycosylated compounds, the anthrone picramnioside F, and the oxanthrone mayoside C, were isolated from the stem bark of Picramnia teapensis, along with the previously reported anthraquinones, 1-O-beta -D- and 8-O-beta -D-glucopyranosyl emodin. The compounds were separated by recycling-HPLC, and their structures were determined on the basis of spectroscopic analysis. CD measurements were used to establish the absolute configuration of the anthrone and oxanthrone. The antifungal activity of 1-O-beta -D- and 8-O--D-glucopyranosyl emodin against Leucoagaricus gongilophorus was shown to be similar to that of the lignan sesamin. (C) 2000 Elsevier B.V. Ltd.

[Proteinogram and serum concentrations of copper, iron and zinc in Santa Ines ewes with Staphylococcus aureus experimentally induced mastitis.] Proteinograma e teores de cobre, ferro e zinco no soro sanguineo de ovelhas da raca Santa Ines com mastite experimental por Staphylococcus aureus. Pesquisa Veterinaria Brasileira 30(5):435-442. Clinica de Bovinos, Campus Garanhuns, Universidade Federal Rural de Pernambuco (UFRPE), Avenida Bom Pastor s/n, Boa Vista, Caixa Postal 152, Garanhuns, PE 55292-901, Brazil. E-mail: carlalopes.mendonca@gmail.comThe aim of the present study was to evaluate the effect of Staphylococcus aureus experimentally induced mastitis on proteinogram and serum concentrations of cupper, iron and zinc levels of Santa Ines primiparous ewes. The right mammary gland of ten healthy ewes was inoculated with 1,0x10(4) UFC/mL of S. aureus. Clinical examination and determination of serum concentrations of proteins by electrophoresis in polyacrylamide gel (SDS-PAGE), cupper, iron and zinc, as well plasma level of fibrinogen were measured before the inoculation (control) and 12h, 24h, 36h, 48h, 60h, 72h, 84h, 96h, 108h, 120h, 132h, 168h, 180h, 288h and 336h after bacteria inoculation. All animals experimentally infected presented clinical mastitis and subsequent loss of mammary gland function. The electrophoretogram allowed the identification of 23 proteins with molecular weights (MW) ranged from 26.000 to 185.000 daltons (Da) including acute-phase proteins, IgG and IgA. A significant increase (P<0,05) in haptoglobin, ceruloplasmin, IgG and IgA concentrations was observed. Antitrypsin and acid glicoprotein concentrations did not alter. The levels of iron and zinc decreased and the cupper concentration increased. A positive correlation between plasma fibrinogen and serum ceruloplasmin (r=0.74), haptoglobin (r=0.62) and IgA (r=0.62) was also identified. Results showed the importance of ceruloplasmin and haptoglobin as acute-phase proteins in ewes with intramammary infections and confirms fibrinogen as an inflammatory marker because its high correlation with specific proteins. The alterations in the serum levels of Cu, Fe and Zn suggest the action of inflammatory mediators triggered by S. aureus.

Desenvolvimento de Planococcus citri (Risso, 1813) (Hemiptera: Pseudococcidae) em cafeeiros

A cochonilha Planococcus citri (Risso, 1813) suga a seiva dos botões florais e frutos do cafeeiro, atacando as rosetas desde a floração até a colheita. Embora seja relatada há alguns anos na cafeicultura, são escassas as informações sobre o desenvolvimento dessa cochonilha em cafeeiros. Assim, o presente trabalho teve por objetivos avaliar alguns aspectos biológicos da fase ninfal de P. citri em plantas de café. Ovos dessa cochonilha foram retirados de uma criação em laboratório, isolados em placas de Petri contendo discos foliares de Coffea arabica L., das cultivares Acaiá Cerrado, Mundo Novo e Catuaí Vermelho e de C. canephora Pierre & Froenher, cultivar Apoatã. As placas foram mantidas em câmara climatizada a 25 ± 1ºC, 70 ± 10% de umidade relativa e 12h de fotofase. Constatou-se que a cultivar Catuaí Vermelho foi a que proporcionou maior duração do período ninfal das fêmeas, porém, não foram constatadas diferenças na mortalidade. Essa cochonilha se desenvolveu satisfatoriamente em todas as cultivares de café estudadas e os resultados não mostraram diferenças claras de susceptibilidade.

Measurement of the p(p)over-bar -> WZ+X cross section at root s=1.96 TeV and limits on WWZ trilinear gauge couplings

We present measurements of the process p (P) over bar -> WZ + X -> l 'nu(l ')l (l) over bar at root s = 1:96 TeV,where l and l ' are electrons or muons. Using 1 fb(-1) of data from the D0 experiment, we observe 13 candidates with an expected background of 4.5 +/- 0.6 events and measure a cross section sigma(WZ) = 2.7(-1.3)(+1.7) pb. From the number of observed events and the Z boson transverse momentum distribution, we limit the trilinear WWZ gauge couplings to -0: 17 <= lambda(Z) <= 0.21 (Delta k(Z) <= 0.29(lambda(Z) = 0) at the 95% C.L. for a form factor scale Lambda = 2 TeV. Further, assuming that Delta g(1)(Z) = Delta k(Z), we find -0.12 <= Delta k(Z) <= 0.29(lambda(Z) = 0) at the 95% C. L. These are the most restrictive limits on the WWZ couplings available to date.

Measurement of inclusive differential cross sections for Upsilon(1S) production in p(p)over-bar collisions at root s=1.96 TeV

We present measurements of the inclusive production cross sections of the Upsilon(1S) bottomonium state in p (p) over bar collisions at root s=1.96 TeV. Using the Upsilon(1S)->mu(+)mu(-) decay mode for a data sample of 159 +/- 10 pb(-1) collected by the D0 detector at the Fermilab Tevatron collider, we determine the differential cross sections as a function of the Upsilon(1S) transverse momentum for three ranges of the Upsilon(1S) rapidity: 0 <\y(Upsilon)\<= 0.6, 0.6 <\y(Upsilon)\<= 1.2, and 1.2 <\y(Upsilon)\<= 1.8.

Measurement of the t(t)over-bar production cross section in p(p)over-bar collisions at root s=1.96 TeV using kinematic characteristics of lepton plus jets events

We present a measurement of the top quark pair production cross section in p (p) over bar collisions at root s=1.96 TeV utilizing 425 pb(-1) of data collected with the D0 detector at the Fermilab Tevatron Collider. We consider the final state of the top quark pair containing one high-p(T) electron or muon and at least four jets. We exploit specific kinematic features of t (t) over bar events to extract the cross section. For a top quark mass of 175 GeV, we measure sigma(t (t) over bar)=6.4(-1.2)(+1.3)(stat)+/- 0.7(syst)+/- 0.4(lum) pb, in good agreement with the standard model prediction.

Search for the flavour-changing neutral current B-s(0)->mu+mu- in p(p)over-bar collisions at root s=1.96 TeV with the D0 dectector

We present the results of a search for the flavor-changing neutral current decay B-s(0)-->mu(+)mu(-) using a data set with integrated luminosity of 240 pb(-1) of p (p) over bar collisions at roots=1.96 TeV collected with the D0 detector in run II of the Fermilab Tevatron collider. We find the upper limit on the branching fraction to be B(B-s(0)-->mu(+)mu(-))less than or equal to5.0x10(-7) at the 95% C.L. assuming no contributions from the decay B-d(0)-->mu(+)mu(-) in the signal region. This limit is the most stringent upper bound on the branching fraction B-s(0)-->mu(+)mu(-) to date.

Search for first-generation scalar leptoquarks in p(p)over-bar collisions at root s=1.96 TeV

We report on a search for pair production of first-generation scalar leptoquarks (LQ) in p (p) over bar collisions at root s=1.96 TeV using an integrated luminosity of 252 pb(-1) collected at the Fermilab Tevatron collider by the D0 detector. We observe no evidence for LQ production in the topologies arising from LQ(LQ) over bar -> eqeq and LQ(LQ) over bar -> eq nu q, and derive 95% C.L. lower limits on the LQ mass as a function of beta, where beta is the branching fraction for LQ -> eq. The limits are 241 and 218 GeV/c(2) for beta=1 and 0.5, respectively. These results are combined with those obtained by D0 at root s=1.8 TeV, which increases these LQ mass limits to 256 and 234 GeV/c(2).

Measurement of the t(t)over-bar production cross section in p(p)over-bar collisions at root s=1.96 TeV using lepton plus jets events with lifetime b-tagging

We present a measurement of the top quark pair (t (t) over bar) production cross section (sigma(t (t) over bar)) in pp collisions at root s = 1.96 TeV using 230 pb(-1) of data collected by the DO experiment at the Fermilab Tevatron Collider. We select events with one charged lepton (electron or muon), missing transverse energy, and jets in the final state. We employ lifetime-based b-jet identification techniques to further enhance the t F purity of the selected sample. For a top quark mass of 175 GeV, we measure sigma(t (t) over bar) 8.6(-1.5)(+1.6) (stat. + syst.) +/- 0.6(lumi.) pb, in agreement with the standard model expectation.

Measurement of the t(t)over-bar production cross section in p(p)over-bar collisions at root s=1.96 TeV using kinematic characteristics of lepton plus jets events

We present a measurement of the top quark pair (t (t) over bar) production cross section (sigma(t (t) over bar)) in pp collisions at a center-of-mass energy of 1.96 TeV using 230 pb(-1) of data collected by the DO detector at the Fermilab Tevatron Collider. We select events with one charged lepton (electron or muon), large missing transverse energy, and at least four jets, and extract the t (t) over bar content of the sample based on the kinematic characteristics of the events. For a top quark mass of 175 GeV, we measure sigma(t (t) over bar) 6.7(-1.3)(+1.4)(stat)(-1.1)(+1.6)(syst) +/- 0.4(lumi) pb, in good agreement with the standard model prediction.
