Pientalon yläpohjarakenteet

Tiivistelmä. Tämän kandidaatintyön tarkoituksena on perehtyä Suomessa rakennettavien pientalojen yläpohjarakenteisiin. Työssä tarkastellaan yläpohjiin kohdistuvien kuormitusten syntymistä, tyypillisiä rakenneratkaisuja, suunnittelu- ja mitoitusperusteita, sekä rakennusfysikaalisten rasitteiden syntymistä ja hallintaa. Työ tehtiin kirjallisuuskatsauksena, jonka pääasiallisina lähteinä toimivat Eurokoodit sekä kotimainen alaa koskeva kirjallisuus. Työn avulla lukija saa yleiskäsityksen pientalojen yläpohjien rakenteesta ja rakenneosista. Lisäksi lukija ymmärtää perusteet yläpohjien rakennesuunnittelun lähtökohdista, kuten kuormitusten laskennasta, kantavien rakenteiden mitoituksesta sekä yläpohjan toiminnallisuudesta kokonaisuudessaan.Roof structures of a detached house. Abstract. The purpose of this bachelor’s thesis is to provide an overview of roof structures in detached houses made in Finland. This thesis examines the development of loads to supporting roof structures, typical structure solutions, design- and sizing criteria along with development and management of a building’s physical burden. The thesis was made as a literary review, where the main sources were Eurocodes and domestic literature in the field. This thesis explains the basics of a roof structure and its structural components. The reader will further understand the fundamentals of a structural designing basis as calculation of loads, sizing of supporting structure and the roof structure functionality in its entirety

Niille määritetään sekä kaarevuutta että kiertymää vastaavat funktiot, näytetään että saadut tulokset ovat loogisesti päteviä ja vastaavat yleistä intuitiota, ja lisäksi todistetaan muutama näiden funktioiden yksiselitteisyyteen liittyvä lause

Day surgery in reduction mammaplasty – saving money or increasing complications?

Background: The benefits of reduction mammoplasty procedures have been reported previously. However, to control the rise in public healthcare costs, we need to find ways of conducting these procedures safely and more cost-effectively. Our aim was to examine whether reduction mammaplasty performed in an outpatient setting has comparable surgical complication rates to those performed in an inpatient setting. We also investigated whether any savings gained from day surgery are still present after any possible indirect costs are considered. Methods: The study population comprised 276 patients who underwent reduction mammaplasty in a single center between January 2019 and February 2021. Data were collected from patient medical records. The costs associated with the primary procedure and any possible additional expenses were calculated. Basic statistical comparisons were performed for propensity score-matched data. Results: Complication rates, readmissions, number of contacts to the health care system, and need for additional surgical interventions were comparable between outpatients and inpatients. The basic costs for outpatients were 2990 euros per patient and 3923 euros for inpatients. Total costs after possible extra expenses were lower in day surgery as it was markedly more cost-effective than patients treated as inpatients. Conclusions: Reduction mammaplasties can be safely performed in an outpatient setting. Moreover, the emergence of complications is comparable to those performed in an inpatient setting. An outpatient setting produced significant cost savings not only in the immediate costs of primary surgery but also in the costs associated with possible complications and extra contacts to the healthcare system.publishedVersionPeer reviewe

Photosystem II Repair and Plant Immunity: Lessons Learned from Arabidopsis Mutant Lacking the THYLAKOID LUMEN PROTEIN 18.3

Chloroplasts play an important role in the cellular sensing of abiotic and biotic stress. Signals originating from photosynthetic light reactions, in the form of redox and pH changes, accumulation of reactive oxygen and electrophile species or stromal metabolites are of key importance in chloroplast retrograde signaling. These signals initiate plant acclimation responses to both abiotic and biotic stresses. To reveal the molecular responses activated by rapid fluctuations in growth light intensity, gene expression analysis was performed with Arabidopsis thaliana wild type and the tlp18.3 mutant plants, the latter showing a stunted growth phenotype under fluctuating light conditions (Biochem. J, 406, 415-425). Expression pattern of genes encoding components of the photosynthetic electron transfer chain did not differ between fluctuating and constant light conditions, neither in wild type nor in tlp18.3 plants, and the composition of the thylakoid membrane protein complexes likewise remained unchanged. Nevertheless, the fluctuating light conditions repressed in wild-type plants a broad spectrum of genes involved in immune responses, which likely resulted from shade-avoidance responses and their intermixing with hormonal signaling. On the contrary, in the tlp18.3 mutant plants there was an imperfect repression of defense-related transcripts upon growth under fluctuating light, possibly by signals originating from minor malfunction of the photosystem II (PSII) repair cycle, which directly or indirectly modulated the transcript abundances of genes related to light perception via phytochromes. Consequently, a strong allocation of resources to defense reactions in the tlp18.3 mutant plants presumably results in the stunted growth phenotype under fluctuating light.</p

Composite Fermion Wavefunctions Derived by Conformal Field Theory

The Jain theory of hierarchical Hall states is reconsidered in the light of recent analyses that have found exact relations between projected Jain wavefunctions and conformal field theory correlators. We show that the underlying conformal theory is precisely given by the W-infinity minimal models introduced earlier. This theory involves a reduction of the multicomponent Abelian theory that is similar to the projection to the lowest Landau level in the Jain approach. The projection yields quasihole excitations obeying non-Abelian fractional statistics. The analysis closely parallels the bosonic conformal theory description of the Pfaffian and Read-Rezayi states.Comment: 4 pages, 1 figur
