A Generic Framework Architecture for Portal Front End

A modem software development requires quick results and excellent quality, which leads to high demand for reusability in design and implementation of software components. The purpose of this thesis was to design and implement a reusable framework for portal front ends, including common portal features, such as authentication and authorization. The aim was also to evaluate frameworks as components of reuse and compare them to other reuse techniques. As the result of this thesis, a goo'd picture of framework's life cycle, problem domain and the actual implementation process of the framework, was obtained. It was also found out that frameworks fit well to solve recurrent and similar problems in a restricted problem domain. The outcome of this thesis was a prototype of a generic framework and an example application built on it. The implemented framework offered an abstract base for the portal front ends, using object-oriented methods and wellknown design patterns. The example application demonstrated the speed and ease of the application development based on the application frameworks.

La traducció del Càntic dels Càntics de Carles Riba

Carles Riba’s activity as a translator of Greek classics (Xenophon, Plutarch, Homer, Sophocles, Euripides, Aeschylus) and works of important authors who wrote in Latin (Virgil), English (Edgar A. Poe) and German (Rilke, Hölderlin) is well known and has been widely studied. In contrast, the great humanist’s translations of books of the Bible -Song of Songs and the Book of Ruth- from Hebrew to Catalan have never been the subject of a monographic study. This piece of work is an edition and a detailed analysis of his version of the Song of Solomon. The notes in the text point out the translator’s contributions and uncertainties in a work published at a pivotal time in the Catalan language’s history

Same Performance Changes after Live High-Train Low in Normobaric vs. Hypobaric Hypoxia.

PURPOSE: We investigated the changes in physiological and performance parameters after a Live High-Train Low (LHTL) altitude camp in normobaric (NH) or hypobaric hypoxia (HH) to reproduce the actual training practices of endurance athletes using a crossover-designed study. METHODS: Well-trained triathletes (n = 16) were split into two groups and completed two 18-day LTHL camps during which they trained at 1100-1200 m and lived at 2250 m (P i O2 = 111.9 ± 0.6 vs. 111.6 ± 0.6 mmHg) under NH (hypoxic chamber; FiO2 18.05 ± 0.03%) or HH (real altitude; barometric pressure 580.2 ± 2.9 mmHg) conditions. The subjects completed the NH and HH camps with a 1-year washout period. Measurements and protocol were identical for both phases of the crossover study. Oxygen saturation (S p O2) was constantly recorded nightly. P i O2 and training loads were matched daily. Blood samples and VO2max were measured before (Pre-) and 1 day after (Post-1) LHTL. A 3-km running-test was performed near sea level before and 1, 7, and 21 days after training camps. RESULTS: Total hypoxic exposure was lower for NH than for HH during LHTL (230 vs. 310 h; P < 0.001). Nocturnal S p O2 was higher in NH than in HH (92.4 ± 1.2 vs. 91.3 ± 1.0%, P < 0.001). VO2max increased to the same extent for NH and HH (4.9 ± 5.6 vs. 3.2 ± 5.1%). No difference was found in hematological parameters. The 3-km run time was significantly faster in both conditions 21 days after LHTL (4.5 ± 5.0 vs. 6.2 ± 6.4% for NH and HH), and no difference between conditions was found at any time. CONCLUSION: Increases in VO2max and performance enhancement were similar between NH and HH conditions.

Development and validation of a stability-indicating UPLC method for rosuvastatin and its related impurities in pharmaceutical dosage forms

The present work describes a novel stability-indicating reversed-phase ultra performance liquid chromatography method for the separation and quantification of rosuvastatin (RSV) and its related impurities in the pharmaceutical dosage forms under forced degradation conditions. An unknown degradation impurity detected in the acid degradation was identified by using quadrupole time-of-flight mass spectrometry. The chromatographic separation was carried out on C-18 column (100 x 2.1 mm, 1.7 μm) using isocratic elution with methanol and 0.1% trifluoroacetic acid (50:50). The total run time was 12 min within which RSV as well as all related impurities and degradation products were separated. The developed method was validated for RSV and related impurities in pharmaceutical dosage forms.

Once methyl myristate (C14:0) is present lower than 0.5% m/m in real samples it was used as an internal standard. The method was successful applied to monitoring basic and acidic catalysis transesterification reactions of vegetable oils such as soybean, canola, corn, sunflower and those used in frying process.

Särmäyksen kustannusperusteinen hinnoittelu

Tässä diplomityössä on tutkittu särmäyksen eri muuttujien vaikutusta kustannusrakenteeseen. Tutkimusmenetelminä on käytetty kirjallisuusselvitystä sekä särmäysaikojen mittausta tuotannossa. Diplomityön tavoitteena oli saada aikaan kustannusperusteinen hinnoittelumalli, jonka avulla särmäyksen hinnoittelu on yksinkertaista ja nopeaa. Särmäysaikoja mitattiin erikokoisille ja -muotoisille kappaleille. Levyn paksuus mitattavilla kappaleilla oli alle 1mm. Muut mitat vaihtelivat alle 200 mm:stä yli 2000 mm:iin. Käytetyt materiaalit olivat sähkö- ja kuumasinkitty teräs. Mitattavia aikoja olivat aika, joka kuluu yhden särmän taivutukseen, aika, joka kuluu yhden kappaleen valmistamiseen sekä ohjelmointiin ja asetuksiin kuluva aika. Särmäysaikoihin vaikuttavat kymmenet eri muuttujat liittyen särmäyspuristimiin, särmättäviin kappaleisiin ja työkaluihin, jne. Osa muuttujista vaikuttaa hyvin vähän kokonaisaikaan, joten kaikkia muuttujia ei lähdetty mittaamaan erikseen. Lisäksi käytössä ollut mittausvälineistö ei ollut riittävän tarkka kaikkien muuttujien mittaamiseen. Aikaansaatu hinnoittelumalli huomioi eri muuttujat ajassa, joka kuluu kappaleiden valmistamiseen, jolloin kaikki muuttujat tulee huomioitua lopullisessa hinnassa.

Web-käyttöliittymän ajonaikainen parametripohjainen luominen

Työssä tutkitaan eri tekniikoita, joilla web-käyttöliittymä voidaan toteuttaa. Tutkituista tekniikoista valitaan työn tavoitteisiin ja rajoitteisiin parhaiten soveltuvat tekniikat, joita käytetään hyväksi luotaessa varsinainen käyttöliittymäkerros olemassa olevalle web-sovellukselle. Varsinaiset käyttöliittymät luodaan automaattisesti työn aikana toteutettavalla käyttöliittymägeneraattorilla, joka käyttää hyväkseen käyttöliittymiä kuvaavia XML-kuvaustiedostoja. Tekniikoista parhaiten tarpeisiimme soveltui AJAX-lähestymistapa, joka mahdollistaa sivun osittaisen päivittämisen ja täten työpöytäsovellusmaisemman käytettävyyden nopeamman sivun päivityksen vuoksi. Käyttöliittymägeneraattorin käyttämät kuvaustiedostot puolestaan mahdollistavat käyttöliittymäkontrollien valmiin mallintamisen yleisessä kontrollikuvaustiedostossa sekä niiden helpon muokkaamisen ja sijoittelun sivu-kohtaisesti. Lisäksi käyttöliittymäkerros sisältää monipuoliset käyttöliittymäkontrollit.

En gestaltning av individens erfarenhetsbaserade kunskap inom diabetesvården

The aim of this study is to form the experience-based knowledge of diabetics. The broader intent is to be able to transform this experience-based knowledge as an asset within caring. In this study, a theoretical contact for the empirical data is presented through phronesis, i.e. practical wisdom. Phronesis can be seen as the most suitable form of knowledge to be able to deepen the individual's understanding of experiencebased knowledge. For this research, hermeneutic phenomenology was chosen. Abductive reasoning was the method chosen to approach the data collected through repeated deep interviews with individuals with personal experience of diabetes and the use of insulin pumps. The abductive approach fascilitates a broader interpretation of the primary empirical results via a theory of philosophy of science, such as phronesis, the life-world and the negativity of the experience. The latent message of the empirical data is thereby also additionally highlighted. The synthesis reveals that experience-based knowledge arrives with time, it is personified and praxis-oriented, and before this time, the knowledge and security must be provided by the established care, by people close to the individual or by other external sources. The experience-based knowledge has strenghts and weaknesses. The knowledge is further categorized by the individual's ability to discern and make judgement. Additionally, the experience-based kowledge is a reflecting and action-based knowledge striving to improve the care provided. The experience-based knowledge held by the individual is potentially a great instrument towards improving general knowledge with possible practical applications within the diabetic care. Furthermost, in practical suggestions to fascilitate care. In generally applying knowledge gathered from the individual's experiental point of view, there are inherent risks. These risks could potentially be eliminated through the adoption of a concept where the established care could function as a quality guarantor. A concept taking into account the experiencebased knowledge as a source of information and knowledge in the care for diabetics. Co-created knowledge and understanding is a position found in both self-care and pump-treatment. It is also found through the optimal application of the experience-based knowledge of the individual as well as the knowledge found within the established care, in order to fascilitate well-being. This as expressed by the individual's phronesis-based knowledge.
