Lappeenrannan teknillisen yliopiston sähkötekniikan osaston uuden kaksivaiheisen tutkintorakenteen kansainvälinen vertailu. Raportti vertailuhankkeen toisesta vaiheesta 15.2.2005

Raportti käsittelee Lappeenrannan teknillisen yliopiston sähkötekniikan uutta kaksivaiheista tutkintorakennetta suhteessa ulkomaisiin vastaaviin master-tasoisiin tutkintorakenteisiin. Tutkimusmenetelmänä käytetään benchmarking-menetelmää. Tutkimusainesto kerätttiin 52:n eurooppalaisen yliopiston www-sivuilta ja opinto-oppaista. Näistä yliopistoista valittiin tarkempaan vertailuun kolme mielenkiintoiseksi vertailukumppaniksi valittua sähkötekniikan koulutusyksikköä: TUL, Technical University of Lodz, Puolasta. TUM,Technical University of München, Saksasta. KTH, Kungliga Tekniska Högskolan, Ruotsi. Toisen vaiheen vertailutulosten valossa näyttää siltä, että kaikkien vertailtujen yliopistojen tutkintojen sisällöt ja määrät ovat samankaltaisia, joten vertailukumppanit oletettavasti kykenevät ymmärtämään eri yliopistojen koulutusohjelmien toteutuksia. Toisaalta sähkötekniikan koulutuksen toteutukset näyttävät vertailuissa yliopistoissa sen verran erilaisilta, että vertailun avulla on mahdollista oppia eri toteutuksien taustalla olevista kulttuurieroista ja tavoitteista, sekä päästä hedelmälliseen yhteistyöhön vertailtavien yliopistojen sähkötekniikan osastojen kanssa.

Removal of Cadmium, Lead and Arsenic from Water by Lactic Acid Bacteria

A number of contaminants such as arsenic, cadmium and lead are released into the environment from natural and anthropogenic sources contaminating food and water. Chronic oral ingestion of arsenic, cadmium and lead is associated with adverse effects in the skin, internal organs and nervous system. In addition to conventional methods, biosorption using inactivated biomasses of algae, fungi and bacteria has been introduced as a novel method for decontamination of toxic metals from water. The aim of this work was to evaluate the applicability of lactic acid bacteria as tools for heavy metal removal from water and characterize their properties for further development of a biofilter. The results established that in addition to removal of mycotoxins, cyanotoxins and heterocyclic amines, lactic acid bacteria have a capacity to bind cationic heavy metals, cadmium and lead. The binding was found to be dependent on the bacterial strain and pH, and occurred rapidly on the bacterial surface, but was reduced in the presence of other cationic metals. The data demonstrates that the metals were bound by electrostatic interactions to cell wall components. Transmission electron micrographs showed the presence of lead deposits on the surface of biomass used in the lead binding studies, indicating involvement of another uptake/binding mechanism. The most efficient strains bound up to 55 mg Cd and 176 mg Pb / g dry biomass. A low removal of anionic As(V) was also observed after chemical modification of the cell wall. Full desorption of bound cadmium and lead using either dilute HNO₃ or EDTA established the reversibility of binding. Removal of both metals was significantly reduced when biomass regenerated with EDTA was used. Biomass regenerated with dilute HNO3 retained its cadmium binding capacity well, but lead binding was reduced. The results established that the cadmium and lead binding capacity of lactic acid bacteria, and factors affecting it, are similar to what has been previously observed for other biomasses used for the same purpose. However, lactic acid bacteria have a capacity to remove other aqueous contaminants such as cyanotoxins, which may give them an additional advantage over the other alternatives. Further studies focusing on immobilization of biomass and the removal of several contaminants simultaneously using immobilized bacteria are required.

Junan matkustajainformaatiojärjestelmän ohjaaminen

Matkustajat pitävät junissa annettavaa informaatiota entistä tärkeämpänä. Tähän haasteeseen pyritään vastaamaan rutiinikuulutusten, kuten asemille tulokuulutusten, automatisoinnilla. Kuulutukset soitetaan ääneen ja esitetään tekstinä näytöillä. Tällöin annettava informaatio on selkeää ja tasalaatuista myös vieraalla kielellä. Junan tiedot, kuten määränpää ja vaunun myyntinumero, esitetään junan ulkoseinällä ovien vierellä junaan nousevia matkustajia varten. Tässä diplomityössä luodaan yleiskatsaus junaväylään liittyviin standardeihin, TCN-standardiin ja UIC-556-määrelehteen. Yleiskatsauksen lisäksi käsitellään tarkemmin matkustajainformaatiojärjestelmään liittyvät osat. Tutustumme myös UIC-176-määrelehteen, joka käsittelee matkustajainformaatiojärjestelmän näyttöjä. Luomme yleiskatsauksen EKE-Elektroniikka Oy:n kehittämään modulaariseen junanhallintajärjestelmään. Työssä suunnitellaan asiakkaan ja standardien vaatimusten pohjalta matkustajainformaatiojärjestelmä, joka on integroitu junanhallintajärjestelmään. Tekstitiedon välittämiseen vaunusta toiseen käytetään WTB-junaväylää. Siinä kommunikoidaan UIC-556-määrelehden mukaisesti, joka mahdollistaa eurooppalaisen yhteensopivuuden. Työn tuloksena on määritelty järjestelmän fyysinen rakenne, ohjelmistorakenne, vaadittavat tietokannat, tiedon syöttäminen järjestelmälle ja junaväylässä käytettävät telegrammit. Erityishaasteena on ratkaistu tilanne, jossa juna jakautuu matkan varrella useampaan suuntaan.

Value co-creation in industrial buyer-seller partnerships - creating and exploiting interdependencies : an empirical case study

In summary the main findings of the study are that there seems to be is no universal definition of value in the context of industrial relationships, but a notion that it is context-, time-, and actor dependent. Value co-creation is a suitable concept in the context of buyerseller relationships. The evolution of a relationship from a transactional to a partnership is long and eventful - a process where the outcome is impossible to estimate in advance. The process is filled with differenttypes of events and also conflicts, which as a matter of fact can be seen as constructive forces in relationship development. The perceived value of a relationship is an antecedent to pursuing a high-involvement strategy; once a partnership exists, the value co-creation potential is realizable through exploiting interdependencies. Those interdependencies are the trigger for value co-creation potential. The value cocreation potential is realized though different processes of value co-creation either to achieve efficiency in exchange or effective use of resources. The logic of buyer-seller partnerships is to create and exploit interdependencies in order to create both efficiency and effective use of resources. (Summary of main findings p. 176)

Makt som fullmakt : ett vårdvetenskapligt perspektiv

The aim of this study is to deepen understanding and knowledge of the concepts and phenomenaof power and authority from the standpoint of caring science. The overall questions of the research are: What is power? What is authority? How do power and authority manifest themselves in the context of caring? How are power and authorityto be understood as caring science concepts? The overall research inception is determination of the concepts in accordance with the hermeneutic approach based on Eriksson's model. The process of understanding follows Gadamer's (1999) hermeneutics. The thesis consists of three part studies. An ontological determinationof the character of the concepts is carried out where a hermeneutic interpretation is made of texts in the Old and the New Testaments in the Bible. The pragmatic features of the concepts are studied on the basis of nurses' written stories of authority and patients' written stories of power and authority. Beside the review of literature concerning power and authority a qualitative meta-analysis ofthe concept and the phenomenon of empowerment are made. The ontological determination shows how a human being's power is the authority to hold every living thing in trust, to tend and care life. To anyone using this authority, serving onesfellow-being is the purpose. Understanding the pragmatical features of authority in the stories of nurses reveals the life-giving nature of serving. By serving the nurse draws near her true mission as a human being, her authority to care for life with love. The service of the nurse and her ability to see and confirm the patient's otherness creates confidence and results in her authority. The nursedoes not abandon the responsibility associated with authority. When the patientdoes not entrust the nurse with authority the nurse employs her inherent authority to alleviate the suffering of the patient. The pragmatical features of the concepts of power and authority in the patients' stories indicate how the nurse puts her power to an improper use if she only makes use of the authority conferred by the hierarchy of power in the organisation, assumes all power and fails to use her faculty for loving care. Patients feel that their existence is threatened when the nurse tries to deprive them of their authority; they experience homelessness, despair and impotence. Patients' struggle for existence and absolute dignity deprives their health processes of strength, and their suffering becomes unbearable. Patients recognize their vitality when encountering a nurse who uses her authority to alleviate the patients' suffering. The power of compassion is strong, and the patients' dignity is recreated when they are able to serve fellowpatients or nurses. The purpose of human life can be understood as the use of one's own inner power and strength. Love.
