Climbing the cosmic ladder with stellar twins in RAVE with Gaia

We apply the twin method to determine parallaxes to 232 545 stars of the RAVE survey using the parallaxes of Gaia DR1 as a reference. To search for twins in this large data set, we apply the t-student stochastic neighbour embedding projection that distributes the data according to their spectral morphology on a two-dimensional map. From this map, we choose the twin candidates for which we calculat

Networking our science to characterize the state, vulnerabilities, and management opportunities of soil organic matter

Soil organic matter (SOM) supports the Earth's ability to sustain terrestrial ecosystems, provide food and fiber, and retains the largest pool of actively cycling carbon. Over 75% of the soil organic carbon (SOC) in the top meter of soil is directly affected by human land use. Large land areas have lost SOC as a result of land use practices, yet there are compensatory opportunities to enhance prod

Man, en och du : Generiska pronomen i svenskans historia

This thesis examines the development of three generic pronouns in the history of the Swedish language, from the year of ca. 1225 until today. The analysis focuses on how the former noun man (‘man’), numeral en (‘one’) and personal pronoun du (‘you’) have turned into generic pronouns, thereby referring to one or a number of arbitrarily chosen human individuals. Furthermore, the study maps how the g

Method for evaluation of renovation measures with regards to moisture and emission loads : Based on risk assessments

Renovating the European building stock has for almost two decades been a matter of importance. For Sweden, it is important to renovate its multifamily buildings in order to achieve a reduced energy use, but also because renovation is needed due to building materials and services reaching (or having passed) the end of their life span. In order to renovate properly, renovation measures must be imple

Random telegraph signal noise in tunneling field-effect transistors with S below 60 mV/decade

Single gate oxide defects in strongly scaled Tunneling Field-Effect Transistors with an inverse subthreshold slope well below 60 mV/decade are investigated by Random Telegraph Signal (RTS) noise measurements. The cause for RTS noise are electrons being captured in and released from individual defects in the gate oxide. Under the assumption that elastic tunneling is the underlying capture and emiss

En skolbyggnads statusbedömning och renoveringsmöjligheter

Med utgångspunkt i Miljöbyggnad, det svenska miljöcertifieringssystemet, har en skolbyggnads status utvärderats. De bedömda indikatorerna inom energi, inomhusmiljö och material gav en bred och övergriplig bild av byggnadens skick och utvärderingen ger en bra grund för det fortsatta arbetet. Skolbyggnaden Kullagymnasiet i Höganäs, Skåne, bedöms nå certifieringsnivån brons, vilket minst motsvarar sa

Erfarenhetsåterföring vid renovering

Nationellt Renoveringscentrum (NRC) bildades 2013 för att arbeta med kunskapshöjning och informationsspridning om en effektiv renoveringsprocess. Centret siktar på att samla och föra vidare kunskap om hur renovering av befintlig bebyggelse kan genomföras både effektivt för involverade aktörer såväl som socialt, ekonomiskt och miljömässigt hållbart för samhället. Kunskap från både akademi och närin

MicroRNAs in Retinal Pathophysiology and Therapeutics

Following identification of tRNA and rRNA, the non-protein coding RNAs (ncRNAs) have been demonstrated to possess catalytic ribozyme functions (Cech et al., 1981; Guerrier-Takada et al., 1983). In recognition of the latter work, T.R. Cech and S. Altman were awarded the 1989 Noble Prize in Chemistry. Fire, et al. (1998) discovered that small double stranded RNA (ds RNA) silences the gene expression

Pioneers for the Basic Understanding of Usher syndrome

After the first description of the inherited nature of bimodal deaf-blindness disease in mid nineteenth century by pioneering ophthalmologists Albrecht von Graefe (May 22, 1828 ± July 20, 1870) and Richard Liebreich (June 30, 1830 - January 19, 1917) followed by its confirmation in early twentieth century from a larger number of patients by another pioneer ophthalmologist Charles Howard Usher (Mar

International Organisations, Authority, and the First Permanent Secretariats in the 19th Century

International organisations (IOs) play increasingly important roles in world politics. As states face more complex challenges they have joined together in IOs to solve their common problems. Yet once an IO has been created it may take on a life of its own, and it becomes difficult for its state founders to control what it does.
