Pro gradu -tutkielman aiheena on luku- ja kirjoitustaidottomien aikuisten maahanmuuttajien suomen kielen kehittyminen puolen vuoden aikana. Tutkimus on kvalitatiivinen ja kvantitatiivinen analyysi, joka mittaa sitä, miten informanttien kielitaito ja luku- ja kirjoitustaito kehittyy puolen vuoden aikana. Tutkimus kuuluu suomi toisena kielenä -tutkimusalaan. Informantteina on 12 luku- ja kirjoitustaidotonta aikuista maahanmuuttajaa. Informantit tekivät puolen vuoden aikana kolme kertaa saman kirjallisen testin. Testi toteutettiin vuoden 2008 kesä-, loka- ja joulukuussa. Lisäksi informantit osallistuivat kirjallisen testin yhteydessä haastatteluun, joka mittaa heidän suullista kielitaitoaan eli puheen ymmärtämistä ja tuottamista. Kirjallinen testi koostuu neljästä tehtävästä ja lokakuussa ja joulukuussa suoritetuista kahdesta lisätehtävästä. Testi mittaa kielen eri osa-alueita: kuullun ymmärtämistä, luetun ymmärtämistä, kirjoittamista ja sanaston hallintaa. Puheosiossa informantit kertoivat kuvasta ja vastasivat kuvasta esitettyihin kysymyksiin. Informanteista neljä on primaarilukutaidottomia eli he eivät osaa lukea eivätkä kirjoittaa millään kielellä ja kahdeksan on sekundaarilukutaidottomia eli he osaavat lukea ja kirjoittaa muulla kuin latinalaisella kirjaimistolla. Sekundaarilukutaidottomat ovat kotoisin Aasiasta ja primaarilukutaidottomat Afrikasta. Viidellä informantilla on suomalainen puoliso. Tuloksista käy ilmi, että kaikki paitsi yksi informantti kehittyvät kesäkuusta joulukuuhun. Kesäkuussa erot eri informanttien välillä ovat huomattavasti suurempia kuin joulukuussa. Joulukuussa erot tasoittuvat. Eniten siis kehittyvät heikoimmat informantit. Yksi informantti ei kehityksestään huolimatta kehittynyt tarpeeksi jatkaakseen seuraavalle tasolle. Muut 11 informanttia saavuttivat mekaanisen lukutaidon ja ovat matkalla kohti funktionaalista lukutaitoa. Tutkimuksen perusteella kaikki muut paitsi yksi informantti hyötyivät suuresti luku- ja kirjoitustaidon kurssista. Kurssin avulla he saivat mahdollisuuden uuteen elämään. Ainakin seitsemän informanttia jatkoi luku- ja kirjoitustaidon kurssin jälkeen suomen kielen kurssille. Kolme opiskelijaa jäi kertaamaan luku- ja kirjoitustaidon kurssia, yksi sai töitä ja yksi, jo kurssin kerrannut, joutui lopettamaan kurssin pysähtyneen kehityksen vuoksi.

Dengue viruses (DENV) serotypes 1, 2, and 3 have been causing yearly outbreaks in Brazil. In this study, we report the reintroduction of DENV2 in the coast of Sao Paulo State. Partial envelope viral genes were sequenced from eighteen patients with dengue fever during the 2010 epidemic. Phylogenetic analysis showed this strain belongs to the American/Asian genotype and was closely related to the virus that circulated in Rio de Janeiro in 2007 and 2008. The phylogeny also showed no clustering by clinical presentation, suggesting that the disease severity could not be explained by distinct variants or genotypes. The time of the most recent common ancestor of American/Asian genotype and the Sao Paulo and Rio de Janeiro (SP/RJ) monophyletic cluster was estimated to be around 40 and 10 years, respectively. Since this virus was first identified in Brazil in 2007, we suggest that it was already circulating in the country before causing the first documented outbreak. This is the first description of the 2010 outbreak in the State of Sao Paulo, Brazil, and should contribute to efforts to control and monitor the spread of DENVs in endemic areas.

Synoptic spectroscopic observations of the U Sco 2010 outburst from maximum light to quiescence as well as a contemporaneous X-ray observation are presented and analyzed. The X-ray spectrum 52 days after outburst indicates a hot source ( kT(bb) similar to 70 eV). Narrow-line components from the irradiated companion atmosphere were observed in hydrogen and helium optical recombination lines. The formation of a nebular spectrum is seen for the first time in this class of recurrent novae, allowing a detailed study of the ejecta using photoionization models. Unusual [O III] auroral-to-nebular line ratios were found and possible scenarios of their origin are discussed. The modeling of the emission line spectrum suggests highly heterogeneous ejecta with masses around or above 3 x 10(-6) M(sun).

Context. To study the evolution of Li in the Galaxy it is necessary to observe dwarf or subgiant stars. These are the only long-lived stars whose present-day atmospheric chemical composition reflects their natal Li abundances according to standard models of stellar evolution. Although Li has been extensively studied in the Galactic disk and halo, to date there has only been one uncertain detection of Li in an unevolved bulge star. Aims. Our aim with this study is to provide the first clear detection of Li in the Galactic bulge, based on an analysis of a dwarf star that has largely retained its initial Li abundance. Methods. We performed a detailed elemental abundance analysis of the bulge dwarf star MOA-2010-BLG-285S using a high-resolution and high signal-to-noise spectrum obtained with the UVES spectrograph at the VLT when the object was optically magnified during a gravitational microlensing event (visual magnification A similar to 550 during observation). The Li abundance was determined through synthetic line profile fitting of the (7)Li resonance doublet line at 670.8 nm. The results have been corrected for departures from LTE. Results. MOA-2010-BLG-285S is, at [Fe/H] = -1.23, the most metal-poor dwarf star detected so far in the Galactic bulge. Its old age (12.5 Gyr) and enhanced [alpha/Fe] ratios agree well with stars in the thick disk at similar metallicities. This star represents the first unambiguous detection of Li in a metal-poor dwarf star in the Galactic bulge. We find an NLTE corrected Li abundance of log epsilon(Li) = 2.16, which is consistent with values derived for Galactic disk and halo dwarf stars at similar metallicities and temperatures. Conclusions. Our results show that there are no signs of Li enrichment or production in the Galactic bulge during its earliest phases. Observations of Li in other galaxies (omega Cen) and other components of the Galaxy suggest further that the Spite plateau is universal.

L-Amino acid oxidases (LAAOs, EC 1.4.3.2) are flavoenzymes that catalyze the stereospecific oxidative deamination of an L-amino acid substrate to the corresponding a-ketoacid with hydrogen peroxide and ammonia production. The present work describes the first report on the antiviral (Dengue virus) and antiprotozoal (trypanocidal and leishmanicide) activities of a Bothrops jararaca L-amino acid oxidase (BjarLAAO-I) and identify its cDNA sequence. Antiparasite effects were inhibited by catalase, suggesting that they are mediated by H(2)O(2) production. Cells infected with DENV-3 virus previously treated with BjarLAAO-I, showed a decrease in viral titer (13-83-fold) when compared with cells infected with untreated viruses. Untreated and treated promastigotes (T. cruzi and L. amazonensis) were observed by transmission electron microscopy with different degrees of damage. Its complete cDNA sequence, with 1452 bp, encoded an open reading frame of 484 amino acid residues with a theoretical molecular weight and pl of 54,771.8 and 5.7, respectively. The cDNA-deduced amino acid sequence of BjarLAAO shows high identity to LAAOs from other snake venoms. Further investigations will be focused on the related molecular and functional correlation of these enzymes. Such a study should provide valuable information for the therapeutic development of new generations of microbicidal drugs. (C) 2008 Elsevier Inc. All rights reserved.
