A química na educação da Princesa Isabel

The private archive of the Brazilian Imperial Family holds a wealth of little known documents about the education of the daughters of Emperor D. Pedro II, especially of the eldest, Isabel, Princess Imperial. Science, particularly chemistry, for which her father had a particular fondness, occupied an important place in the girl's education. The study of these documents sheds a new light on the contrast between female education in the country in general, during most of the 19th century, and the careful upbringing envisaged by the Emperor for his future successor.

The present study describes stages involved in evaluating drug preventive programs and contemplates the main considerations to take into account to make this type of evaluation more effective in line with recommendations by the main programs evaluation guides

Els «criteris de visibilització de les dones» en català: límits sintacticosemàntics i discursius

L'objectiu d'aquest article és analitzar els principals criteris que les guies d'estil recomanen per visibilitzar les dones ¿o per fer un ús no sexista del llenguatge¿ des de dos punts de vista: el sintacticosemàntic i el discursiu. Des del punt de vista sintacticosemàntic, s'estudien bàsicament els fenòmens relacionats amb la coordinació, la concordança i la repetició o elisió d'elements (per exemple, especificadors del nom), i la manera com les diferents opcions afecten el significat oracional. Des del punt de vista discursiu, s'analitzen els fenòmens relacionats amb la coreferència; és a dir, la relació entre les diferents maneres d'expressar un mateix referent per mitjà d'elements nominals al llarg del text, i l'efecte que provoquen en el text en conjunt. Amb aquest objectiu, l'estudi analitza des d'un punt de vista qualitatiu les dades proporcionades per un corpus de textos procedents de tres àmbits (polític, administratiu i educatiu) en què s'apliquen sovint aquesta mena de criteris. Paraules clau: català, llenguatge no sexista, visibilització lingüística de les dones, sintaxi, cohesió, coreferència, llenguatge androcèntric, estil. The goal of this article is to analyse the main criteria recommended by style guides aimed at making women more visible or, in other words, to make a non-sexist use of language. I will concentrate on two main aspects: the syntactic-semantic and the discursive. From a syntactic-semantic point of view, the main elements being studied are those related to coordination, agreement and repetition or omission of elements (for instance, noun specifiers), and also the way the different options chosen affect the meaning of the sentence. From a discursive and stylistic point of view, the elements analysed are those related to coreference, that is, the relationship between the different ways of expressing a same referent through different elements in the text, and the effect they produce in the text as a whole. Having this as the main goal, the study analyses from a qualitative point of view the data from a corpus in three different areas (politics, administration and education), which often apply this kind of criteria. Keywords: Catalan, non-sexist language, female linguistic visibility, syntax, cohesion, co-reference, androcentric language, style

Identificação da influência do descarte de lodo de estações de tratamento de água

The growing concern of environmental surveillance of the quality of hydric resources guides the development of research on management of residues generated in water treatment plants (WTP). Approximately 8.000 WTPs in Brazil operate without a treatment program of the residues, disposing these effluents in the environment. This work evaluated WTP discharges into watercourses by collecting superficial waters, sediments and benthic samples at the town of Registro, São Paulo State, Brazil. Even though superficial waters and benthic samples showed no further contamination, sediment analysis pointed out that aluminum deposits detected near sludge discharges may represent a potential risk to the environment.

Análisis del proceso de adquisición del código audiovisual y de la intervención de los agentes que forman a los ciudadanos en el conocimiento de los medios

The research group Gre‐TICE (Grupo de investigación en tecnologías de la Información y la Comunicación en Educación) has the acquisition of the multimedia language and their use as a form of expression as one of their lines of research. During the academic year 2002‐ 2003, following previous work in the use of ICT in Education, commenced upon the project: “The acquisition of visual and sound codes and the processes related to the visual media”. The intention of this project is to study how formal or non‐formal education context can help young adults and children to acquire visual and sound codes to become ‘critical consumers’ with the media and to use the tools in a creative way. To achieve this objective, the project team has developed a partner group which includes professional from different European regions; including teachers and managers from across the age spectrum, government institutions and cultural organisations. Whilst the project will call upon qualitative analysis of the previous projects / research, it will seek to develop ‘Good Practice’ guides and other resources/ materials to be disseminated to project partners (and others) to build innovative actions throughout the European region

Sampling in chemical analysis

The uncertainty of any analytical determination depends on analysis and sampling. Uncertainty arising from sampling is usually not controlled and methods for its evaluation are still little known. Pierre Gy’s sampling theory is currently the most complete theory about samplingwhich also takes the design of the sampling equipment into account. Guides dealing with the practical issues of sampling also exist, published by international organizations such as EURACHEM, IUPAC (International Union of Pure and Applied Chemistry) and ISO (International Organization for Standardization). In this work Gy’s sampling theory was applied to several cases, including the analysis of chromite concentration estimated on SEM (Scanning Electron Microscope) images and estimation of the total uncertainty of a drug dissolution procedure. The results clearly show that Gy’s sampling theory can be utilized in both of the above-mentioned cases and that the uncertainties achieved are reliable. Variographic experiments introduced in Gy’s sampling theory are beneficially applied in analyzing the uncertainty of auto-correlated data sets such as industrial process data and environmental discharges. The periodic behaviour of these kinds of processes can be observed by variographic analysis as well as with fast Fourier transformation and auto-correlation functions. With variographic analysis, the uncertainties are estimated as a function of the sampling interval. This is advantageous when environmental data or process data are analyzed as it can be easily estimated how the sampling interval is affecting the overall uncertainty. If the sampling frequency is too high, unnecessary resources will be used. On the other hand, if a frequency is too low, the uncertainty of the determination may be unacceptably high. Variographic methods can also be utilized to estimate the uncertainty of spectral data produced by modern instruments. Since spectral data are multivariate, methods such as Principal Component Analysis (PCA) are needed when the data are analyzed. Optimization of a sampling plan increases the reliability of the analytical process which might at the end have beneficial effects on the economics of chemical analysis,

Approaching the experiences of young immigrants for the citizenship learning

This thesis seeks to answer the question: how do the participation experiences of young girl immigrant contribute to citizenship learning? Citizenship learning in youth comes from different contexts(family, school, friends and leisure and ambiguous) –where participation experiences take place–, combined with interpersonal relationships and personal dispositions (BiestaLawy& Kelly, 2009). So that, I want to know which are the young girl immigrants’ contextsand relationships and which kind of learning comes from each one. In addition, being young, girl and immigrant, are categories to take into account to understand their learnings.

DFMA-ohjeistuksen laatiminen tuulivoimateollisuuden mekaniikkasuunnittelijoille

Osien hyvä valmistettavuus on aina asettanut haasteita suunnittelulle. Yritysten verkostoituminen lisää haasteellisuutta, kun tuotteiden suunnittelu tehdään erillään kokoonpanosta ja osavalmistus tapahtuu alihankintana. Tällöin on ensiarvoisen tärkeää, että suunnittelulla on tarvittavat perustiedot eri valmistusmenetelmistä, jotta suunniteltujen osien valmistus ja kokoonpano luonnistuu ongelmitta. Työn alun kirjallisuusosiossa käsitellään suunnittelun teoriaa, joka toimii perustana hyvälle osasuunnittelulle. Teorian lisäksi työssä käsitellään eri työmenetelmiä koskevat rajoitukset ja mahdollisuudet. Oikein suunniteltu osa on työstömenetelmien kannalta hyvin valmistettavissa, työ voidaan tehdä taloudellisilla työmenetelmillä ja kokoonpanossa osat sopivat yhteen ilman sovitustyötä. Käytännön osuudessa on käsitelty The Switch Drive Systems Oy:n tuotteiden valmistettavuuden kehityskohteita, joilla tuotteiden valmistettavuutta voidaan parantaa. Kehityskohteiden perusteella on laadittu valmistusmenetelmäkohtainen suunnittelun ohjeistus, jonka avulla kehitetään The Switchin suunnittelua vastaamaan paremmin laitetoimittajien tarpeisiin. Näiden ohjeistuksien avulla voidaan kehittää suunnittelutyötä siten, että osien valmistettavuus sekä laatu paranevat ja kokoonpano nopeutuu.

Jätehuoltosuunnitelman laatiminen elektroniikka-alan yritykselle

Sähkö- ja elektroniikka-alan yritykset eivät yleensä kuormita merkittävästi ympäristöä, sillä teollisuudenalan suurimmat ympäristövaikutukset aiheutuvat alihankkijoiden ja komponenttivalmistajien toiminnasta. Yritysten oma toiminta perustuu pitkälti tuotekehitykseen ja tuotteiden loppukokoonpanoon valmiista komponenteista. Syntynyt jäte on tyypillisesti pääosin pakkausjätettä, metalleja, kaatopaikkajätettä ja vähäisessä määrin myös ongelmajätettä. Vähäisen ympäristökuormituksen johdosta yrityksiltä ei yleensä vaadita ympäristölupaa. Diplomityössä laadittiin jätehuoltosuunnitelma elektroniikka-alan yritykselle. Työ suoritettiin Kemppi Oy:n toimeksiannosta Lahdessa. Jätehuoltosuunnitelman noudattaminen parantaa yrityksen julkisuuskuvaa ja tuo kustannussäästöjä. Toimivan suunnitelman laatiminen vaatii kuitenkin aikaa ja muita resursseja. Jätehuollon toimivuus on tarkistettava säännöllisesti, etenkin silloin kun yrityksen toiminnan painopiste muuttuu. Käytännön osuudessa kartoitettiin edellisvuosien jätemäärät ja yrityksen jätehuollon tila. Jätehuoltosuunnitelman laatimiselle oli selkeä tarve, koska jätehuolto perustui osin kirjoittamattomiin sääntöihin ja vanhoihin tottumuksiin. Syntypaikkalajittelua tehostettiin lisäämällä jäteastioita ja -pisteitä jätteiden syntypaikoille. Lajittelua parannettiin myös laatimalla selkeät ohjeet ja kouluttamalla työntekijöitä.
