Signals of QCD instanton-induced processes are searched for in deep-inelastic scattering (DIS) at the electron-proton collider HERA in a kinematic region defined by the Bjorken-scaling variables x > 10(-3), 0.1 < y < 0.6 and photon virtualities 10 less than or similar to Q(2) < 100 GeV2. Several observables characterising hadronic final state properties of QCD instanton-induced events are exploite
Measurements are presented of inclusive charm and beauty cross sections in e(+)p collisions at HERA for values of photon virtuality 12 <= Q(2) = 60 GeV2 and of the Bjorken scaling variable 0.0002 <= x <= 0.005. The fractions of events containing charm and beauty quarks are determined using a method based on the impact parameter, in the transverse plane, of tracks to the primary vertex, as measured
The production fractions of charged and neutral b-hadrons in b-quark events from Z(0) decays have been measured with the DELPHI detector at LEP. An algorithm has been developed, based on a neural network, to estimate the charge of the weakly-decaying b-hadron by distinguishing its decay products from particles produced at the primary vertex. From the data taken in the years 1994 and 1995, the frac
The concept of a circular economy (CE) has gained traction in the EU as a pathway towards sustainability. However, beyond the goal of closing resource loops there is no consensus on the key components of CE. Efforts to triangulate a definition of CE found that it is mainly a model for economic prosperity that aims to reconcile economic growth with sustainability. In 2020, the Swedish government ad
Den främsta orsaken till en ökad växthuseffekt anses idag bero på en högre koncentrationav koldioxid i atmosfären. Sedan den industriella revolutionen harmänniskan påverkat mängden koldioxid i atmosfären genom aktiviteter så somförbränning av fossila bränslen, avskogning, förändringar i markanvändning, samtcementproduktion. För att kunna motverka framtida klimatförändringar krävs enfördjupad kunskThis thesis focuses on the development and application of efficient mathematicaltools for estimating and modelling the exchange of carbon dioxide (CO2) between the Earth and its atmosphere; here referred to as the global CO2 surface flux.There are two main approaches for estimating the CO2 flux: Processed based(bottom-up) modelling and atmospheric inversion (top-down) modelling.

Glas är ett genomsiktligt material som används i byggnader för att utforma miljöer som är ljusa och upplevs som öppna. Modernt byggnadsglas används i konstruktioner som utsätts för betydande laster jämfört med ett traditionellt fönsterglas. Som exempel kan nämnas trappsteg, balustrader, golv, tak och väggpaneler där glasets geometriska utformning kan vara mer eller mindre komplex. Det finns ett beNovel and increased use of glass in building construction has been made possible, as a result of methods of mass production introduced during the 20th century and advanced computational structural analyses. With modern use of glass structures, a range of demands emerge which need to be addressed in the strength design process. The aim of the thesis work has been to develop experimentally verified
At temperate latitudes, altricial birds and their nestlings need to handle night temperatures well below thermoneutrality during the breeding season. Thus, energy costs of thermoregulation might constrain nestling growth, and low nocturnal temperatures might require resources that parents could otherwise have invested into nestlings during the day. To manipulate parental work rate, we performed brAt temperate latitudes, altricial birds and their nestlings need to handle night temperatures well below thermoneutrality during the breeding season.

Background:Membranous expression of the anti-adhesive glycoprotein podocalyxin-like (PODXL) has previously been found to correlate with poor prognosis in several major cancer forms. Here we examined the prognostic impact of PODXL expression in urothelial bladder cancer.Methods:Immunohistochemical PODXL expression was examined in tissue microarrays with tumours from two independent cohorts of patie
