Höyryturbiinin käytönaikaisen suorituskyvyn seuranta

Tässä diplomityössä jatkettiin Loviisan voimalaitoksen höyryturbiinien suorituskyvyn parannuspotentiaalien tutkimusta. Tavoitteena oli kehittää laitoksen höyryturbiinien suorituskyvyn käytönaikaisia on-line-mittauksia. Selvityksessä perehdyttiin norjalaisen IFE:n kehittämään stationääritilan TEMPOohjelmaan( The Thermal Performance Monitoring And Optimisation system), sen käyttöohjeisiin ja toimintaperiaatteisiin. Työssä esiteltiin laajasti tiedon yhteensovittamisen laskentateoriaa, johon TEMPOn toiminta perustuu. Työssä tarkasteltiin turbiinin todellista paisuntaprosessia, koska sen ymmärtäminen on tärkeässä osassa turbiinin suorituskyvyn valvonnassa. Tutkimuksessa esiteltiin myös turbiineille mahdollisia vikoja sekä niiden syntymisprosesseja. Työssä tarkasteltiin TEMPOn sovittamien tulostiedostojen analysointiohjelman toimivuutta havaitsemalla itse aiheutettuja poikkeamia todellisiin mittaustiedostoihin. Analysointiohjelmalla muodostettuja kuvaajia vertailtiin todellisen prosessin ajotilanteen kuvaajiin ja tarkasteltiin, kuinka poikkeamia on mahdollista havaita kuvaajien avulla. TEMPO-ohjelmalle löydettiin tutkimuksen edetessä kehittämisehdotuksia. Näillä muutoksilla ohjelma saadaan mallintamaan Loviisan voimalaitoksen turbiiniprosessia tarkemmin ja tuloksista saadaan hyödyllisempiä.

Importance of multidisciplinary trauma prevention program for youth

OBJECTIVE: present the experience of the P.A.R.T.Y. program in Campinas, thereby changing the habits of young people.METHODS: The organizers visited the participating schools talking to the students, who are aged between 14-18 years. These students spent an afternoon at the Clinics Hospital of Unicamp, where, for four hours, they attended lectures of the organizers, partners and municipal sectors, and also visited the hospital, talking with trauma victims. Questionnaires were evaluated between2010-2012, being applied before and after the project.RESULTS:2,450 high school students attended the program. The mean age is 16 ± 0,99 years and 37.6% were male. 3.6% of males already drive while drunk versus 0.8% of women. Before the project 116 (11.3%) thought that drunk driving wasn't a risk, and only 37 (3.6%) knew the alcohol effects. After the project, 441 (43%) began to consider drunk driving a risk and 193 (18.8%) know the alcohol effects when driving. 956 (93.3%) considered that prevention projects have a huge impact on their formation.CONCLUSION: It's expected that the attendees will act as multipliers of information, conveying the message of prevention to their entire social circles resulting in reduction in the number of trauma events involving the young, in the long term.

Professional development among educators pursuing a B.Ed. program in special education in Tanzania : a study of motives and perceived outcomes

Implementation of different policies and plans aiming at providing education for all is a challenge in Tanzania. The need for educators and professionals with relevant knowledge and qualifications in special education is substantial. Teacher education does not equip educators with sufficient knowledge and skills in special education and professional development programs in special education are few in number. Up to 2005 no degree programs in special education at university level were available in Tanzania. The B.Ed. Special Education program offered by the Open University of Tanzania in collaboration with Åbo Akademi University in Finland was one of the efforts aimed at addressing the big national need for teachers and other professionals with degree qualifications in special education. This pilot program offered unique possibilities to study professional development in Tanzania. The research group in this study consisted of the group of students who participated in the degree program 2005-2007. The study is guided by three theoretical perspectives: individual, social and societal. The individual perspective emphasizes psychological factors as motives, motivation, achievement, self-directed behavior and personal growth. Within social perspective, professional development is viewed as situated within the social and cultural context. The third perspective, the societal, focuses on change, reforms, innovations and transformation of school systems and societies. Accordingly, professional development is viewed as an individual, social and societal phenomenon. The overall aim of the study is to explore the participants’ motives for participating in a B.Ed. Special Education program and the perceived outcomes of the program in terms of professional development. In order to achieve the objectives of the study, a case study approach was adopted. Questionnaires and semi-structured interviews were administered in three waves between January 2007 and February 2009 to the 35 educators participating in the B.Ed. Special Education program. The findings of the study reveal that the participants expressed motives which were related to job performance, knowledge, skills, academic degree and career. Also altruistic motives were expressed by the participants in terms of helping and supporting students with special needs and their communities. The perceived outcomes of the program were in line with the expressed motives. However, the results indicate that the participants also learned new skills, as interaction skills and guidance and counseling skills. Increased self-confidence was also mentioned as an outcome. The participants also got deepened understanding of disability issues. In addition, they learned strategies for creating awareness of persons with disability in the communities. Thus the findings of the study indicate positive outcomes of the program in terms of professional development. The conclusion of the study is that individual, social and societal factors interact when it comes to explaining why Tanzanian educators in special education choose to pursue a degree program in special education. The individual motives, as increased knowledge and better prospects of career development interact with the social and societal motives to help and support vulnerable student groups. The study contributes to increased understanding of the complexity of professional development and of the realities educators meet when educational reforms are implemented in a developing country.

Effects of hyperprolactinemia and ovariectomy on the tibial epiphyseal growth plate and bone formation in mice

PURPOSE: To evaluate the effects of ovariectomy and the hyperprolactinemia procedure in the tibial epiphyseal growth plate of female mice.METHODS: In this study, the epiphyseal growth plate of ovariectomized (OVX) and/or rendered hyperprolactinemic female mice by 50 days of treatment with 200 μg metoclopramide (M) was evaluated morphologically, morphometrically and immuno-histochemically. Forty female and adult mice were divided into four groups according to treatment: V group - animals treated with saline solution; H group - hyperprolactinemic animals; Ovx/V group - ovariectomized animals and treated with saline solution; Ovx/H group - hyperprolactinemic and ovariectomized animals. After the treatment period, the animals were sacrificed, tibia was removed and fixed in 10% buffered formalin and decalcified in 10% formic acid. The material was immersed in paraffin and subjected to histological processing in paraffin. The sections were stained with Masson's trichrome and immunohistochemistry was carried out for the pro-apoptotic protein BCL-2. The images for the morphological and morphometric study were analyzed with the imaging program AxioVision 4.8 (Carl-Zeiss(r), Germany).RESULTS: The combination of hyperprolactinemia and the ovariectomy procedure decreased the number of resting chondrocytes 1.5-fold, the number of proliferative chondrocytes 1.8-fold; the percentage of resting cartilage 2.4-fold and the percentage of trabecular bone 2.1-fold, compared with respective control animals.CONCLUSION: The procedure of ovariectomy combined with the metoclopramide-induced hyperprolactinemia in female mice has showed marked bone degeneration due to significant decrease of cell proliferation in the epiphyseal growth plate and bone formation.

Evaluation of Bubble Formation and Break Up in Suppression Pools by Using Pattern Recognition Methods

During a possible loss of coolant accident in BWRs, a large amount of steam will be released from the reactor pressure vessel to the suppression pool. Steam will be condensed into the suppression pool causing dynamic and structural loads to the pool. The formation and break up of bubbles can be measured by visual observation using a suitable pattern recognition algorithm. The aim of this study was to improve the preliminary pattern recognition algorithm, developed by Vesa Tanskanen in his doctoral dissertation, by using MATLAB. Video material from the PPOOLEX test facility, recorded during thermal stratification and mixing experiments, was used as a reference in the development of the algorithm. The developed algorithm consists of two parts: the pattern recognition of the bubbles and the analysis of recognized bubble images. The bubble recognition works well, but some errors will appear due to the complex structure of the pool. The results of the image analysis were reasonable. The volume and the surface area of the bubbles were not evaluated. Chugging frequencies calculated by using FFT fitted well into the results of oscillation frequencies measured in the experiments. The pattern recognition algorithm works in the conditions it is designed for. If the measurement configuration will be changed, some modifications have to be done. Numerous improvements are proposed for the future 3D equipment.

University Image vs. University Identity: Congruence between Expectations and Experience

The aim of this thesis was to examine congruencies between university identity and university images of prospective and current students. Therefore, factors essentially influencing on expected and experienced university images were identified. Providing an understanding on the differences in the formation of both concepts allowed the analysis of potential incongruities between a university’s identity and the perceptions its students hold. The study was conducted in July and August 2013 at Lappeenranta University of Technology by means of a web-based research survey. The sample consisted of 160 international Master’s degree students who were admitted in 2011, 2012 and 2013. Descriptive and multivariate statistical analysis methods were used to process the data. The results of the study indicated statistically significant incongruities between the case university’s identity and its students’ images. Further, the expected and experienced university images showed incongruities to each other. Deviations were additionally detected to be dependent on the students’ home regions. All in all, there is potential for an improvement of the students’ experiences resulting from a low perception of the student’s preparation for future job life.

Determinants of Polylepis (Rosaceae) Forest Distribution and Treeline Formation in the High Andes

High elevation treelines are formed under common temperature conditions worldwide, but the functional mechanisms that ultimately constrain tree growth are poorly known. In addition to environmental constraints, the distribution of high elevation forests is largely affected by human influence. Andean Polylepis (Rosaceae) forests are an example of such a case, forests commonly growing in isolated stands disconnected from the lower elevation montane forests. There has been ample discussion as to the role of environmental versus anthropogenic causes of this fragmented distribution of Polylepis forests, but the importance of different factors is still unclear. In this thesis, I studied functional, environmental and anthropogenic aspects determining Polylepis forest distribution. Specifically, I assessed the degree of genetic determinism in the functional traits that enable Polylepis species to grow in cold and dry conditions. I also studied the role of environment and human influence constraining Polylepis forest distribution. I found evidence of genetically determined climatic adaptations in the functional traits of Polylepis. High elevation species had reduced leaf size and increased root tip abundance compared to low elevation species. Thus these traits have potentially played an important role in species evolution and adaptation to high elevation habitats, especially to low temperatures. I also found reduced photosynthesis rate among high elevation tree species compared to low elevation species, supporting carbon source limitation at treelines. At low elevations, Polylepis forest distribution appeared to be largely defined by human influence. This suggests that the absence of Polylepis forests in large areas in the Andes is the result of several environmental and anthropogenic constraints, the role of environment becoming stronger towards high elevations. I also show that Polylepis trees grow at remarkably low air and soil temperatures near treelines, and present new evidence of the role of air temperatures in constraining tree growth at high elevations. I further show that easily measurable indices of accessibility are related to the degree of degradation of Polylepis forest, and can therefore be used in the rapid identification of potentially degraded Polylepis forests. This is of great importance for the conservation and restoration planning of Polylepis forests in the Andes. In a global context, the results of this thesis add to our scientific knowledge concerning high elevation adaptations in trees, and increase our understanding of the factors constraining tree growth and forest distribution at high-­elevation treelines worldwide.

Kansallisen energia- ja ilmastopolitiikan toteuttaminen puolustushallinnossa

Tässä diplomityössä selvitetään kansallisen energia- ja ilmastopolitiikan toteuttamiseen vaikuttavia tekijöitä puolustushallinnossa. Tavoitteena on tunnistaa, minkälaisia haasteita ja edellytyksiä toteuttamiseen liittyy ja minkälaisia toimenpiteitä ja päätöksiä politiikan toteuttaminen hallinnossa edellyttää. Tutkimuskysymyksiä lähestytään strategiakirjallisuuden, olemassa olevan tutkimustiedon sekä kvalitatiivisen haastattelututkimuksen kautta. Tutkimuksen tarkoitus on edesauttaa hallinnon oman energia- ja ilmastostrategian laadintaa sekä toimia johdon työkaluna toteuttamispäätösten tekemisessä. Merkittävimmiksi toteuttamiseen vaikuttaviksi tekijöiksi tunnistettiin resursointikysymykset, johdon sitoutuminen sekä puolustustoimialan erityispiirteet. Lisäksi vaikutuksia tunnistettiin olevan muun muassa kiinteistö- ja energiasopimusjärjestelyillä, asenteilla sekä puolustusvoimauudistuksella. Kirjallisuuskatsauksen teoreettisille käsitteille löydettiin pitkälti vastineet empiirisestä tutkimuksesta, mutta osa haasteista nousi esiin nimenomaan puolustushallinnon toimintaympäristöstä. Osa tuloksista on yleistettävissä laajemmin energia- ja ilmastotoimenpiteille, valtiosektorille ja muille toimialoille. Saatujen tulosten perusteella on mahdollista määrittää reunaehdot hallinnonalan oman energia- ja ilmasto-ohjelman laadinnalle sekä ennakoida toteuttamisedellytyksiä. Ohjelman toteuttamista tukevina jatkotoimenpide-ehdotuksina esitetään yhteistyöverkoston yhteistä julkista sitoutumista energia- ja ilmastopolitiikan edistämiseen, konkreettisten toimintaohjelmien laatimista sekä tietoisuuden kasvattamista toiminnan ilmastovaikutuksista ja ilmastonmuutoksen vaikutuksista toimintaan viestinnän ja seurantajärjestelmien keinoin sekä osana päätöksentekoprosesseja.

Yrittäjyyskasvatus yhteistyöverkostoissa

Tutkimus käsittelee Yrittäjyyskasvatuksen Mittariston -projektia, jossa tutkimuskohteena on peruskoulun ensimmäisen asteen luokan- ja aineenopettajien näkemys ja kokemus yrittäjyyskasvatuksen verkostoyhteistyöstä. Tutkimuksen tarkoituksena oli selvittää miten hyvin opettajat tuntevat verkostoyhteistyötä, mikä on heidän tietämyksensä yrittäjyyskasvatuksesta ja kuinka tämä näkyy heidän työssään ja opetuksessaan. Tutkimuksen otos on 450 opettajaa. Tulokset analysoitiin SPSS-tilastomenetelmäohjelmalla. Tilastollisina tutkimusmenetelminä käytettiin jakaumien frekvenssianalyysiä, Faktori­analyysin Pääkomponenttianalyysiä ja Kaksisuuntaista varianssianalyysia (Anova). Tutkimuksen johtopäätöksenä voidaan todeta, että opettajien tiedot yhteistyö-verkostojen tarjoamista palveluista ovat hyvin hajanaiset. Ongelma jatkuu helposti niin kauan kunnes opettajien koulutusohjelmaan tuodaan lisää yrittäjyyskasvatus- ja yrittäjyysopintoja. Tämä pitäisi huomioida myös tulevissa opetussuunnitelmissa. Tämän tutkimuksen tavoitteena oli tuoda esille Yrittäjyyskasvatuksen mittariston tulosten kautta yrittäjyyskasvatuksen nykytila, tuoda ratkaisuja ehdotusten kautta opetukseen ja herättää keskustelua yrittäjyyskasvatuksen parantamiseksi.

Sellutehtaan TRS-hajapäästöjen hallinta

Diplomityön tavoitteena on selvittää TRS-hajapäästöjen muodostumista sekä päästöjen määrää UPM Kymmene Oyj:n Kaukaan sellu- ja paperitehtaalla. Työssä laaditaan TRS-hajapäästöjen mittausohjelma, minkä päivitetty massa- ja paperiteollisuuden BAT-vertailuasiakirja vaatii. Mittausohjelma täydentää tehdasintegraatin ilmapäästöjen valvontaohjelmaa. Hajapäästöjen lisäksi tavoitteena on selvittää häiriötilanteiden aiheuttamia TRS-päästömääriä. Kirjallisuusosassa selvitetään hajujen muodostumista sellun ja paperin valmistuksessa ja niiden käsittelyä ympäristövaikutusten minimoimiseksi. Lisäksi esitellään mittausmenetelmiä. Kokeellisessa osassa valituista kohteista mitataan TRS-pitoisuudet ja hajukaasujen virtaama, joiden perusteella lasketaan TRS-kuormitus. Kuormitus suhteutetaan sellutonnille. Osa kohteista on hajapäästökohteita ja osa kohteita, joista hajukaasut häiriötilanteissa johdetaan käsittelemättä ulos. Tulosten perusteella TRS-hajapäästöjä muodostuu sellun valmistuksessa noin 0,04 kgS/ADt ja jätevedenkäsittelyssä, pääasiassa lietteenkäsittelyssä 0,04 kgS/ADt. Hajapäästöjä syntyy eniten kohteissa, missä keräily on toteutettu kevyemmin tai sitä ei ole. Merkittävimmät kohteet Kaukaalla ovat lietteenkäsittely, koivukuitulinja ja mäntyöljylaitos. Havulinjan ja talteenotto-osaston hajapäästöt ovat muita osastoja vähäisemmät. Yhteensä sellutehtaan ja lietteenkäsittelyn TRS-hajapäästömäärä on 0,08 kgS/ADt, mikä on BAT vaihteluvälin (0,05-0,2 kgS/ADt) sisällä. TRS-häiriöpäästöjen osuus tehtaan TRS päästöistä voi häiriötilanteiden toistuessa nousta merkittäviksi. Tähän vaikuttaa merkittävästi häiriintyvä kohde.

The mental health of graduate students at the Federal University of São Paulo: a preliminary report

We present data regarding the care provided to graduate level health professionals at the mental health center of the Federal University of São Paulo. From September 1996 to September 2003, 146 graduate students (99 in the Master's degree program and 47 in the Doctoral program) were attended. This population was predominantly female (68.5%), with a mean (± SD) age of 28.6 ± 4.42 years, not married (71.9%). Most of the subjects were professionals who had not graduated from the Federal University (78.1%). The students who sought help for psychological and/or psychiatric problems were classified into two categories: situational-adaptive crises and psychopathological crises. The main diagnoses were depression and anxiety disorders (44%) causing 4.5% of the subjects to be temporarily suspended from their graduate studies; 19.2% reported that they had used psychotropic drugs within the previous month, and 47.9% referred to sleep disturbances. Suicidal tendencies were mentioned by 18% of those interviewed. Students with emotional disturbances and academic dysfunctions should be recognized at an early stage, and it is fundamental for them to have access to mental health programs that provide formal, structured and confidential care. Thus, it is important that professors and advisors in graduate programs build a warm and affective learning environment. If we consider the expressive growth in Brazilian scientific production resulting from the implementation of an extensive national system of graduate education, it is important to focus efforts on enhancing and upgrading the mental health care system.

Financial support of graduate programs in Brazil: quo vadis?

Graduate programs provide the highest level of formal education and thus are crucial for the development of any country. However, official Brazilian data clearly show a dramatic decrease in the number and values of scholarships available to graduate programs in Brazil over the last few years, despite the importance and growth of such programs. Between 1995 and 2004, investment by the Coordenadoria de Aperfeiçoamento de Pessoal do Ensino Superior (CAPES, subordinate to the Ministry of Education and Culture) in funding scholarships, corrected for inflation in the period, actually decreased by 51%. In addition, during the period between 1994 and 2004, there was a loss of about 60% in the purchasing power of the graduate scholarships provided by CAPES and the National Council for Science and Technology (CNPq). To reverse this trend, we propose the development of sectorial funding for Brazilian graduate programs to guarantee the availability and continuity of financial support for this strategic activity.
