Horizontal Grid Size Selection and its Influence on Mesoscale Model Simulations

The use of two-dimensional spectral analysis applied to terrain heights in order to determine characteristic terrain spatial scales and its subsequent use for the objective definition of an adequate grid size required to resolve terrain forcing are presented in this paper. In order to illustrate the influence of grid size, atmospheric flow in a complex terrain area of the Spanish east coast is simulated by the Regional Atmospheric Modeling System (RAMS) mesoscale numerical model using different horizontal grid resolutions. In this area, a grid size of 2 km is required to account for 95% of terrain variance. Comparison among results of the different simulations shows that, although the main wind behavior does not change dramatically, some small-scale features appear when using a resolution of 2 km or finer. Horizontal flow pattern differences are significant both in the nighttime, when terrain forcing is more relevant, and in the daytime, when thermal forcing is dominant. Vertical structures also are investigated, and results show that vertical advection is influenced highly by the horizontal grid size during the daytime period. The turbulent kinetic energy and potential temperature vertical cross sections show substantial differences in the structure of the planetary boundary layer for each model configuration

Clinical usefulness of the Screen for Cognitive Impairment in Psychiatry (SCIP-S) scale in patients with type I bipolar disorder

Background: The relevance of persistent cognitive deficits to the pathogenesis and prognosis of bipolar disorders (BD) is understudied, and its translation into clinical practice has been limited by the absence of brief methods assessing cognitive status in Psychiatry. This investigation assessed the psychometric properties of the Spanish version of the Screen for Cognitive Impairment in Psychiatry (SCIP-S) for the detection of cognitive impairment in BD. Methods: After short training, psychiatrists at 40 outpatient clinics administered the SCIP three times over two weeks to a total of 76 consecutive type I BD admissions. Experienced psychologists also administered a comprehensive battery of standard neuropsychological instruments to clinical sample and 45 healthy control subjects. Results: Feasibility was supported by a brief administration time (approximately 15 minutes) and minimal scoring errors. The reliability of the SCIP was confirmed by good equivalence of forms, acceptable stability (ICC range 0.59 to 0.87) and adequate internal consistency (Chronbach's alpha of 0.74). Construct validity was granted by extraction of a single factor (accounting 52% of the variance), acceptable correlations with conventional neuropsychological instruments, and a clear differentiation between bipolar I and normal samples. Efficiency was also provided by the adequate sensitivity and specificity. Limitations: The sample size is not very large. The SCIP and the neurocognitive battery do not cover all potentially relevant cognitive domains. Also, sensitivity to change remains unexplored. Conclusion: With minimal training, physicians obtained a reliable and valid estimate of cognitive impairment in approximately 15 minutes from an application of the SCIP to type I BD patients.

Otra mirada al tema del cambio de escala: los nuevos espacios de comercio, ocio y turismo = Another look at the theme of the change of scale: new spaces in commerce, leisure and tourism

The technological advances and new organisation of the economy together with a change in ideas in consumer habits andlifestyle that have happened in the last 25 years have placed us in a new state of capitalism. The spatial translation of thisnew state has been immediate and implies among other changes the overcoming of the concept of scale. Commercialspaces and those of leisure and tourism offer us an unbeatable opportunity of exemplifying these changes because they arethe most effected by the new postmodern tendencies

Brain size and evolutionary diversification in birds

The role of behavior in evolution remains controversial, despite that some ideas are over 100 years old. Changes in behavior are generally believed to enhance evolution by exposing individuals to new selective pressures and by facilitating range expansions. However, this hypothesis lacks firm empirical evidence. Moreover, behavioral changes can also inhibit evolution by hiding heritable variation from natural selection. Taking advantage of the complete phylogeny of extant birds, a new species-level measure of past diversification rate and the best existing measures of brain size (n = 1326 species), I show here that relative brain size is associated (albeit weakly) with diversification rates. Assuming that brain relative size reflects behavioral flexibility, an assumption well-supported by evidence, this finding supports the idea that behavior can enhance evolutionary diversification. This view is further supported by the discovery that the most important factor influencing diversification rates is ecological generalism, which is believed to require behavioral flexibility. Thus, behavioral changes that expose animals to a variety of environments can have played an important role in the evolution of birds.

Inertization of small-scale chemical wastes using iron phosphate glass

The viability of small-scale heavy-metal waste immobilization into iron phosphate glasses was investigated. Several waste forms containing different amounts of heavy-ion wastes were evaluated (5%, 10%, 15%, 20%, 26%, 33%, 40% and 50% by mass) and their X-ray diffraction patterns revealed that no crystallization occurred in glasses with waste concentrations up to 26%. The dissolution rates for all of the reported glass compositions (ca. 10-8 g cm-2 min-1) are similar to those reported for the materials most commonly used for waste vitrification. Iron phosphate glasses thus proved to be very useful for the immobilization of heavy-metal wastes, exhibiting good contention and chemical durability comparable to that of borosilicate glasses.

Design and implementation of a multipurpose reactor for scale-up studies

In the theoretical part, the different polymerisation catalysts are introduced and the phenomena related to mixing in the stirred tank reactor are presented. Also the advantages and challenges related to scale-up are discussed. The aim of the applied part was to design and implement an intermediate-sized reactor useful for scale-up studies. The reactor setting was tested making one batch of Ziegler–Natta polypropylene catalyst. The catalyst preparation with a designed equipment setting succeeded and the catalyst was analysed. The analyses of the catalyst were done, because the properties of the catalyst were compared to the normal properties of Ziegler–Natta polypropylene catalyst. The total titanium content of the catalyst was slightly higher than in normal Ziegler–Natta polypropylene catalyst, but the magnesium and aluminium content of the catalyst were in the normal level. By adjusting the siphonation tube and adding one washing step the titanium content of the catalyst could be decreased. The particle size of the catalyst was small, but the activity was in a normal range. The size of the catalyst particles could be increased by decreasing the stirring speed. During the test run, it was noticed that some improvements for the designed equipment setting could be done. For example more valves for the chemical feed line need to be added to ensure inert conditions during the catalyst preparation. Also nitrogen for the reactor needs to separate from other nitrogen line. With this change the pressure in the reactor can be kept as desired during the catalyst preparation. The proposals for improvements are presented in the applied part. After these improvements are done, the equipment setting is ready for start-up. The computational fluid dynamics model for the designed reactor was provided by cooperation with Lappeenranta University of Technology. The experiments showed that for adequate mixing with one impeller, stirring speed of 600 rpm is needed. The computational fluid dynamics model with two impellers showed that there was no difference in the mixing efficiency if the upper impeller were pumping downwards or upwards.

Idea- ja innovaatioporfolion hallinta

Tässä kandidaatintyössä tarkastellaan idea- ja innovaatioportfolion hallintaa, portfoliojohtamista sekä näihin soveltuvia erilaisia menetelmiä yrityksen näkökulmasta. Tavoitteena on luoda yleiskatsaus yleisimpiin käytettyihin menetelmiin ja viitekehyksiin. Lähteinä työssä on käytetty sähköisiä tietokantoja ja alan kirjallisuutta. Käytetyimmät portfolion hallintamenetelmät voidaan jakaa neljään ryhmään: taloudelliset ja rahamääräiset mittarit, liiketoimintastrategiat, portfoliokartat tai kupla-diagrammit, scorecard:it eli pisteytystaulukot sekä tarkistuslistat. Idea- ja innovaatioportfolion hallinnan tavoitteena on luoda yrityksen kannalta mahdollisimman tehokas ja tuottava portfolio, joka on kuitenkin linjassa yrityksen strategian kanssa. Portfolion projekteille jaettavissa olevat resurssit ovat niukat, joten resurssien jakoon ja tehokkaaseen hyödyntämiseen tulee kiinnittää huomiota. Portfolion tasapainottamiseksi on hyvä tarkastella kehitys- ja tutkimusprojektien määrää, kokoa ja riskiä. Teknologiatiekartta on yrityksen strateginen työkalu, jolla se voi suunnata toimintaansa kohti sen visiota. Teknologiatiekartta koostuu yrityksen valitsemista markkinoista, niille suunnatuista tuotteista tai palveluista, sekä näiden vaatimista tuotekehitysprojekteista ja teknologioista. Projektien etenemistä voidaan tarkastella stage-gate -mallin avulla. Stage-gate jakaa projektin porteilla eri vaiheisiin. Jokaisen portin läpäistäkseen projektin tulee täyttää sille asetetut vaatimukset. Menetelmät eivät takaa menestystä, vaan yrityksen on valittava itselleen sopivat menetelmät siten, että ne tukevat portfoliojohtamista ja sopivat yhteen yrityskulttuurin kanssa. Pelkkä mittareihin tuijottaminen ei riitä, vaan niiden taakse on myös osattava katsoa ja huomioida yrityksen strategia.

Näiden tekijöiden puuttuminen estää kasvun. Yrityksen kasvua estäviä muita tekijöitä ovat tutkimuksen mukaan mikroyritysten liiallinen paikallisuus, yhteistyön vähäisyys sekä yrittäjän liiallinen kietoutuminen liiketoimintaan että toiminnan liian vähäinen strateginen suunnittelu.

Small and Large Scale Dynamics in the Milky Way

This thesis contains dynamical analysis on four different scales: the Solar system, the Sun itself, the Solar neighbourhood, and the central region of the Milky Way galaxy. All of these topics have been handled through methods of potential theory and statistics. The central topic of the thesis is the orbits of stars in the Milky Way. An introduction into the general structure of the Milky Way is presented, with an emphasis on the evolution of the observed value for the scale-length of the Milky Way disc and the observations of two separate bars in the Milky Way. The basics of potential theory are also presented, as well as a developed potential model for the Milky Way. An implementation of the backwards restricted integration method is shown, rounding off the basic principles used in the dynamical studies of this thesis. The thesis looks at the orbit of the Sun, and its impact on the Oort cloud comets (Paper IV), showing that there is a clear link between these two dynamical systems. The statistical atypicalness of the orbit of the Sun is questioned (Paper I), concluding that there is some statistical typicalness to the orbit of the Sun, although it is not very significant. This does depend slightly on whether one includes a bar, or not, as a bar has a clear effect on the dynamical features seen in the Solar neighbourhood (Paper III). This method can be used to find the possible properties of a bar. Finally, we look at the effect of a bar on a statistical system in the Milky Way, seeing that there are not only interesting effects depending on the mass and size of the bar, but also how bars can capture disc stars (Paper II).

A study of combustion phenomena in circulating fluidized beds by developing and applying experimental and modelling methods for laboratory-scale reactors

The results shown in this thesis are based on selected publications of the 2000s decade. The work was carried out in several national and EC funded public research projects and in close cooperation with industrial partners. The main objective of the thesis was to study and quantify the most important phenomena of circulating fluidized bed combustors by developing and applying proper experimental and modelling methods using laboratory scale equipments. An understanding of the phenomena plays an essential role in the development of combustion and emission performance, and the availability and controls of CFB boilers. Experimental procedures to study fuel combustion behaviour under CFB conditions are presented in the thesis. Steady state and dynamic measurements under well controlled conditions were carried out to produce the data needed for the development of high efficiency, utility scale CFB technology. The importance of combustion control and furnace dynamics is emphasized when CFB boilers are scaled up with a once through steam cycle. Qualitative information on fuel combustion characteristics was obtained directly by comparing flue gas oxygen responses during the impulse change experiments with fuel feed. A one-dimensional, time dependent model was developed to analyse the measurement data Emission formation was studied combined with fuel combustion behaviour. Correlations were developed for NO, N2O, CO and char loading, as a function of temperature and oxygen concentration in the bed area. An online method to characterize char loading under CFB conditions was developed and validated with the pilot scale CFB tests. Finally, a new method to control air and fuel feeds in CFB combustion was introduced. The method is based on models and an analysis of the fluctuation of the flue gas oxygen concentration. The effect of high oxygen concentrations on fuel combustion behaviour was also studied to evaluate the potential of CFB boilers to apply oxygenfiring technology to CCS. In future studies, it will be necessary to go through the whole scale up chain from laboratory phenomena devices through pilot scale test rigs to large scale, commercial boilers in order to validate the applicability and scalability of the, results. This thesis shows the chain between the laboratory scale phenomena test rig (bench scale) and the CFB process test rig (pilot). CFB technology has been scaled up successfully from an industrial scale to a utility scale during the last decade. The work shown in the thesis, for its part, has supported the development by producing new detailed information on combustion under CFB conditions.

Molecular modeling of asymmetric induction in heterogeneously catalyzed hydrogenation of the C=O bond

Modifiering av metallytor med starkt adsorberade kirala organiska molekyler är eventuellt den mest relevanta teknik man vet i dag för att skapa kirala ytor. Den kan utnyttjas i katalytisk produktion av enantiomeriskt rena kirala föreningar som behövs t.ex. som läkemedel och aromkemikalier. Trots många fördelar av asymmetrisk heterogen katalys jämfört med andra sätt för att få kirala föreningar, har den ändå inte blivit ett allmänt verktyg för storskaliga tillämpningar. Detta beror t.ex. på brist på djupare kunskaper i katalytiska reaktionsmekanismer och ursprunget för asymmetrisk induktion. I denna studie användes molekylmodelleringstekniker för att studera asymmetriska, heterogena katalytiska system, speciellt hydrering av prokirala karbonylföreningar till motsvarande kirala alkoholer på cinchona-alkaloidmodifierade Pt-katalysatorer. 1-Fenyl-1,2-propandion (PPD) och några andra föreningar, som innehåller en prokiral C=O-grupp, användes som reaktanter. Konformationer av reaktanter och cinchona-alkaloider (som kallas modifierare) samt vätebundna 1:1-komplex mellan dem studerades i gas- och lösningsfas med metoder som baserar sig på vågfunktionsteori och täthetsfunktionalteori (DFT). För beräkningen av protonaffiniteter användes också högst noggranna kombinationsmetoder såsom G2(MP2). Den relativa populationen av modifierarnas konformationer varierade som funktion av modifieraren, dess protonering och lösningsmedlet. Flera reaktant–modifierareinteraktionsgeometrier beaktades. Slutsatserna på riktning av stereoselektivitet baserade sig på den relativa termodynamiska stabiliteten av de diastereomeriska reaktant–modifierare-komplexen samt energierna hos π- och π*-orbitalerna i den reaktiva karbonylgruppen. Adsorption och reaktioner på Pt(111)-ytan betraktades med DFT. Regioselektivitet i hydreringen av PPD och 2,3-hexandion kunde förklaras med molekyl–yta-interaktioner. Storleken och formen av klustret använt för att beskriva Pt-ytan inverkade inte bara på adsorptionsenergierna utan också på de relativa stabiliteterna av olika adsorptionsstrukturer av en molekyl. Populationerna av modifierarnas konformationer i gas- och lösningsfas korrelerade inte med populationerna på Pt-ytan eller med enantioselektiviteten i hydreringen av PPD på Pt–cinchona-katalysatorer. Vissa modifierares konformationer och reaktant–modifierare-interaktionsgeometrier var stabila bara på metallytan. Teoretiskt beräknade potentialenergiprofiler för hydrering av kirala α-hydroxiketoner på Pt implicerade preferens för parvis additionsmekanism för väte och selektiviteter i harmoni med experimenten. De uppnådda resultaten ökar uppfattningen om kirala heterogena katalytiska system och kunde därför utnyttjas i utvecklingen av nya, mera aktiva och selektiva kirala katalysatorer.

Kuituvuoto reikäsihdillä massan syöttövaiheessa

Diplomityön tarkoituksena oli kehittää tutkimuslaite, jolla pystyttäisiin tutkimaan sellumassan syöttötapahtumaa reikäsihdillä ja tarkastelemaan syöttöhetkellä tapahtuvaa kuituhäviötä. Laitteen suunnittelun ja valmistuksen tavoitteena oli myös saada tutkimuslaite mahdollisim-man modifioitavaksi (syöttöaukon koko, muoto ja erityyppiset reikäsihdit ja näiden vaikutukset sellukuitujen hävikkiin). Haluttiin myös mahdollisuus syöttötapahtuman kuvaamiseen esim. suurnopeuskameroin, joka otettiinkin huomioon laiteosia valittaessa (läpinäkyvä akryyli). Tutkimuslaitteen kestävyyttä erilaisissa prosessiolosuhteissa haluttiin korostaa (voidaan operoida laajalla pH ja lämpötila-alueilla, sekä syöttöpainetta voidaan muunnella). Diplomityön kirjallisuusosassa käsitellään kuituvuodon aiheuttamia haittoja, joista tärkein on taloudellinen menetys. Näiden lisäksi kirjallisuusosassa tarkastellaan pääpirteittäin pesume-netelmiä ja käydään läpi kuitusulpun suotautumiseen vaikuttavia tekijöitä. Diplomityöhön sisältyi tutkimuslaitteen suunnittelun ja valmistuksen lisäksi myös laitteen toi-mivuuden testaus. Testit suoritettiin pohjoismaisella koivusellulla. Koivusellu otettiin happi-vaiheen jälkeisen pesurin poistosta. Massalle suoritettiin KAPPA-luvun, SR-luvun, viskositee-tin ja syrjäytys -määritykset, sekä kuituanalyysi. Laitteella suoritettiin 7 %, 10 % ja 12 % sakeuksisten massojen koeajotestit. Suodokset otettiin talteen jatkotutkimuksiin, jossa niistä mitattiin kuituvuoto. 10 % suodokselle suoritettiin myös kuituanalyysi. Tuloksista nähtiin, että 7 % sakeuksinen massa antoi lähes nelinkertaisen kuituvuotomäärän 10 % sakeuksiseen massan syöttöön nähden.

Rukoile ja työtä tee. Onni Puhakan kehitys innovaattorista oman tien kulkijaksi

Pray and work. The development of Onni Puhakka: from innovator to nonconformist This ethnological biographical study examines the modernization which began in the mid-1800s, continued into the mid-1900s, and has changed Finnish society in many ways. This era has been studied on a general level quite extensively, but this work explores the life and everyday experiences of Onni Puhakka (1870−1955), a farmer who spent most of his life in the town of Liperi. The goal is to find new perspectives on the development of the modernization process in society through the experiences of an individual. In this study, a central theme is the rural co-operative movement represented in Finland by Pellervo as well as its development in this country and as a significant undertaking in Onni Puhakka’s life. The co-operative movement was one of the most significant sectors affecting modernization in rural communities. The main character in the study is the grandfather of the present author, and thus this research belongs to the newly accepted ethnological research tradition of studying one’s own community. Written documents, mainly collected and preserved by Onni Puhakka himself during his lifetime, form the research material. The material consists mainly of Puhakka’s extensive correspondence, personal notes and diaries, documents related to his farm, and photographs taken by him. Earlier research and other written material examining the general development of the period were used to provide a background for the study. The co-operative movement formed a comprehensive ideology for Onni Puhakka, in which the possibilities for the development of both individuals and the community were combined. His life was based on a religious conviction, and he felt that the co-operative movement was the application of Christian love for one’s neighbour in practice. At the beginning of his active working career, Puhakka was an innovator, a reformer at the forefront of progress, but quite soon he became a sworn critic of the development of the co-operative movement in particular. One of Puhakka’s criticisms of the co-operative movement was the shifting of decision-making power to professional managers and central organizations, far from the reach of local actors. A fundamental reason for his dissatisfaction was the development within the co-operative movement in which the ideological background was forgotten, and economic goals and making a profit took an excessive significance. This assessment of the co-operative movement made by Onni Puhakka and his predictions about its development were not unfounded. This has been shown by several studies examining the development of both the Pellervo and working class cooperative movements. The professionalization of management, managerialism, as well as the direct links between professional managers of local co-operatives and central organizations have lead to the situation in which fewer and fewer people make the decisions, and management has as its goal economic success and growth. Co-operative enterprises that have grown in size have become estranged from the everyday life of their members. Instead of taking care of relations with the membership of the co-op, competitive ability and the market share have become the most important concerns of the management. As the membership has become alienated, their interest in large-scale co-ops has also become largely economic. A significant change among the membership of the Pellervo movement occurred at the stage when the co-operative movement shifted from rural areas to urban centres. This meant that the commitment of the membership became much looser than it had been in the farmers’ production and consumer co-ops. From the point of view of its members, the nature of the co-operative movement has become diametrically opposed to its point of departure: the active members who previously formed the subject of the co-operative movement have become the object of the economic activities of that same movement. The co-operative movement has been transformed from the progressive agent of change of its early years into a business activity which no longer has any significant task as a social reformer. This study confirms the observations of the latest research on modernization which states that modernization has not been a straightforward and inevitable development that has lead to the present situation. For example, the criticism directed by Puhakka toward the co-operative movement includes information that shows that a few others who were initially actively involved also criticized the development of the movement. Despite his occasional frustration, Onni Puhakka continued his criticism and attempts to get the co-operative movement to change its course and return to its ‘roots’. In the early years of the cooperative movement he probably did not differ much from the other pioneers in the sense that many of them had adopted and internalized the same values and motive for being involved that he had. However, Puhakka differed from his colleagues in the sense that he was able to believe in what he called the “fundamental values” of the co-operative movement longer than many of them.

Atomikerroskasvatuksen soveltaminen kemiantekniikassa

Tässä kirjallisuustyössä tutkittiin atomikerroskasvatuksen (ALD) soveltamista kemiantekniikassa. Työn alussa kerrottiin atomikerroskasvatuksesta, sen toimintaperiaatteista ja prosessitekniikasta. Tämän jälkeen tutkittiin viittä eri kemiantekniikan sovellusta, jotka olivat polymeerien pinnoittaminen, heterogeenisten katalyyttien syntetisointi, membraanien modifiointi, korroosionesto ja kaasunilmaisimet. ALD on ohutkalvotekniikka, jolla voidaan valmistaa nanometrin tai jopa Ångströmin (1 Å = 0.1 nm) tarkkuudella epäorgaanisia materiaalikerroksia, jotka yleensä ovat metallioksideja, kuten alumiinioksidi. ALD perustuu kaasu-kiintoainereaktioihin, joissa kaasumaiset kemialliset prekursorit reagoivat vuorotellen kasvualustan kanssa. Tyypilliset prekursorit ovat metalliligandi ja vesi, joka on yleisin hapen lähde ALD-reaktioissa. ALD−reaktiot suoritetaan yleensä matalassa paineessa (100−200 Pa) ja korkeassa lämpötilassa (200–400 °C) suljetussa reaktorikammiossa. ALD-prosesseissa voidaan hyödyntää myös plasmaa alentamaan reaktiolämpötiloja. Plasman avulla prekursoreista luodaan hyvin reaktiivisia radikaaleja, jotka voivat reagoida jopa huoneenlämmössä. Lämpöherkkiä polymeerejä voidaan pinnoittaa ohutkalvoilla, joilla voidaan lisätä esimerkiksi pakkausmateriaalien suojaa happea ja vesihöyryä vastaan. ALD:llä voidaan syntetisoida tarkasti nanomittakaavan heterogeenisiä katalyyttejä, joilla on korkea dispersio tukimateriaalin pinnalla. ALD:n avulla voidaan säästää katalyyttimateriaalia menettämättä katalyytin aktiivisuutta, mikä on tärkeää monien katalyyttisovellusten taloudellisuuden kannalta, esimerkiksi polttokennot. ALD soveltuu hyvin membraanien modifiointiin, koska kaasumaiset prekursorit leviävät tasaisesti membraanin huokosiin. Membraanien pinnoittamisella pyritään vaikuttamaan, selektiivisyyteen, hydrofiilisyyteen, liuotinkestävyyteen, huokoskokoon ja sen jakaumaan. Lisäksi membraaneja voidaan pinnoittaa katalyyttisillä ohutkalvoilla, mikä on tärkeää nanoreaktoreiden kehityksen kannalta. ALD:llä voidaan pinnoittaa esimerkiksi terästä, ja vähentää täten teräksen korroosiota. Puolijohtavia metallioksideja voidaan käyttää kaasunilmaisimina, joiden valmistuksessa ALD:n tarkkuudesta on suurta hyötyä.
