Medans världens fossila bränslereserver sinar har utvinningen av fossilgas genom hydraulisk spräckning, allmänt känt som fracking, vunnit mark internationellt. Parallellt med detta uppenbarar sig klimatförändringarnas katastrofala effekter och tiden är knapp för att ställa om global energiproduktion innan medeltemperaturen når så kallade ”tipping points”. Syftet med denna uppsats är att utforska dAs the world is running out on conventional fossil fuel reserves the extraction of fossil gas through hydraulic fracturing, commonly known as fracking, has gained further ground internationally. In parallel, the escalating and disastrous effects of climate change are evident and time is running out to adjust energy production systems in order to avoid tipping points of global temperature levels.

Abstract: Recently, a crystal structure of V-nitrogenase was presented, showing that one of the µ2 sulphide ions in the active site (S2B) is replaced by a lighter atom, suggested to be NH or NH2, i.e. representing a reaction intermediate. Moreover, a sulphur atom is found 7 Å from the S2B site, suggested to represent a storage site for this ion when it is displaced. We have re-evaluated this struc

Popular Abstract in Swedish Två av de viktigaste polyaminerna påträffades redan i slutet av 1600-talet, som kristaller i tjursperma och har därför fått namnen spermin och spermidin. Dessa aminer bildas från en annan substans, putrescin, som först isolerades från ruttnande kött. Namnet putrescin kommer från engelskans putrefaction, som betyder förruttnelse. Polyaminer, som kemiskt sett är positivt The polyamines putrescine, spermidine and spermine are essential for cell growth and differentiation. The biosynthesis of polyamines are tightly regulated by feedback mechanisms involving two enzymes, namely ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase (AdoMetDC). This thesis deals with the mechanisms behind the polyamine-mediated feedback control of these enzymes. The poly

Popular Abstract in Swedish Kroppens fettceller innehåller en energidepå i form av s.k. triglycerider, en glycerolmolekyl med tre påkopplade fettsyror, som kan användas vid behov (fasta, arbete och dylikt). För att kroppens andra celler ska kunna använda fettdepåerna som energikälla, måste fettsyrorna frikopplas från glycerolmolekylen och skickas ut ur fettcellerna till blodet. Fettsyrorna transpoThe primary role of hormone-sensitive lipase (HSL), an 84 kDa enzyme of 768 amino acids (in the rat protein), is to hydrolyse stored triacylglycerols in adipocytes of white adipose tissue. Catecholamines and insulin regulate lipolysis through cellular signalling. A major target of this regulation is HSL, activated through phosphorylation by cAMP-dependent protein kinase (cAMP-PK). Insulin activate

Sammanfattning Titel: Affärssystembranschen - En studie av branschens förutsättningar Författare: Peter Colliander, Jacob Lundblad, Sophie Monsén Handledare: Hans Knutsson Problem: Affärssystembranschen genomgår idag en omvälvande fas då nya aktörer kommer in på marknaden samtidigt som den tekniska utvecklingen går allt fortare och befintliga aktörer ändrar strategier. Konjunkturläget bidrar till

INTRODUCTION: Tau positron emission tomography (PET) is a reliable neuroimaging technique for assessing regional load of tau pathology in the brain, but its routine clinical use is limited by cost and accessibility barriers. METHODS: We thoroughly investigated the ability of various machine learning models to predict clinically useful tau-PET composites (load and laterality index) from low-cost an

In the present work we determine the adsorption site of two polyatomic molecules, methoxy and ethoxy, on Cu(100). This is accomplished by comparing experimental intramolecular vibrational modes to the corresponding modes calculated by first principle methods. We explore the three different high symmetry adsorption sites on top, bridge and hollow using several different metal clusters to represent

Estimating temporal trends in spatially structured populations has a critical role to play in understanding regional changes in biological populations and developing management strategies. Designing effective monitoring programmes to estimate these trends requires important decisions to be made about how to allocate sampling effort among spatial replicates (i.e. number of sites) and temporal repli

The vegetation component in climate models has advanced since the late 1960s from a uniform prescription of surface parameters to plant functional types (PFTs) PFTs are used in global land-surface models to provide parameter values for every model grid cell With a simple photosynthesis model we derive parameters for all site years within the Fluxnet eddy covariance data set We compare the model pa

Ecosystem phenology plays an important role in carbon exchange processes and can be derived from continuous records of carbon dioxide (CO2) exchange data. In this study we examined the potential use of phenological indices for characterizing cumulative annual CO2 exchange in four contrasting northern peatland ecosystems. We used the approach of Jonsson and Eklundh (2004) to derive a set of phenolo

Particulate methane monooxygenase (pMMO) is an enzyme that converts methane into methanol at ambient temperature and pressure. Over the past three decades, the metal content and location of the active site have been highly controversial. Recent single-particle cryogenic electron-microscopy (cryo-EM) structures have furthered this debate. In this study, three cryo-EM structures (PDB entries 7s4h, 7

Electrochemical real-time monitoring of ligand binding to an engineered opioid receptor specific for morphine is reported. In the particular systems studied, 90% of the binding was found to be completed after only 85-120 s. Thus, the binding kinetics has proven to be more rapid than previously believed. The observed association rate constant for the morphine binding reaction was calculated to be 2

Background: Despite improved surgical and oncological treatment, ovarian cancer continues to be the most lethal of the gynecologic malignancies. We aimed to analyze survival trends in epithelial ovarian cancer with regard to age, tumor site, and morphology in Sweden 1960 to 2014. Methods: A nationwide population-based study was conducted using data from the Swedish Cancer Registry on 46,350 women

Nitrogenase is the only enzyme that can cleave the triple bond in N2, making nitrogen avaiable for other organisms. It contains a complicated MoFe7S9C(homocitrate) cluster in its active site. Many computational studies with density-functional theory (DFT) of the nitrogenase enzyme have been presented, but they do not show any consensus-they do not even agree where the first four protons should be
