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

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

Det ligger en mångtydighet att ha sitt ursprung i ett land men bo i ett annat. Ursprungslandets vardagsliv med symboler och kultur omger inte individen som flyttat till ett annat land. Syftet med denna uppsats är att få en förståelse för hur utlandssvenska kvinnor i New York uppfattar sin kulturella identitet och hur deras förhållande till Sverige ter sig.

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

Knowledge of species-environment associations is critical for the management of threatened amphibian populations facing habitat fragmentation and a restricted range. The Coastal Giant Salamander (Dicamptodon tenebrosus) is subject to habitat degradation from logging and human development and is classified as Threatened at its northern range limit in British Columbia, Canada. We examined habitat as

The aim was to produce a thermostable enzyme that could be used to remove sugar residues from glucosylated natural products classified as flavonoids by applying a method combining extraction in hot pressurized water with enzymatic hydrolysis.

Ovarian cancer is the seventh most common cancer in women globally, with approximately 240,000 new cases annually. Although a rare disease, it is the most lethal gynecologic malignancy. Unspecific symptoms result in late diagnosis and a generally poor prognosis. However, ovarian cancer is a heterogeneous disease comprising different disease entities, which is of importance in clinical decision-mak

Deep learning has the potential to drastically increase the accuracy and efficiency of prostate cancer diagnosis, which would be of uttermost use. Today the diagnosis is determined manually from H&E stained specimens using a light microscope. In this paper several different approaches based on convolutional neural networks for prostate cancer classification are presented and compared, using th

Populärvetenskaplig sammanfattning: Mössbauerspektra är en metod som används för att bestämma hur ett mineral, eller molekyl, är uppbyggt. Man undersöker ett visst grundämne, inom geologin undersöker man oftast järn. Efter att ha analyserat ett prov i spektrometern kan man få uppgifter om var och hur järnet sitter i mineralet, eller molekylen. Metoden bygger på att man skickar gammastrålning av eThe Mössbauer effect is used in this work to determine the oxidation and site occupation in biotites that have been treated in different pHs. The work also gives an introduction to the theory behind the Mössbauer effect as well as Mössbauer spectroscopy. It is obvious that the pH has a significant role in the oxidation of the biotites, the more acidic the sample the more it will be oxidised. It is

Det intrycket som hon och hennes vänner gav mig av ämnet, utbildningen och arbetsmöjligheterna inom yrket var avgörande för mitt val av just juristprogrammet. Tidigare har jag läst bland annat psykologi,

Microsoftdomen grundar sig i att Microsoft vägrat lämna ut interoperabilitetsinformation till en av sina konkurrenter (Sun). Sun menar att detta konstituerar ett missbruk av dominerande ställning och lämnar in ett klagomål till Kommissionen som påbörjar en utredning. Kommissionen börjar dessutom på egen hand utreda huruvida Microsofts integration av Windows Media Player i sitt operativsystem (Wind

In this study, we simulated heterotrophic CO2 (Rh) fluxes at six European peatland sites using the ECOSSE model and compared them to estimates of Rh made from eddy covariance (EC) measurements. The sites are spread over four countries with different climates, vegetation and management. Annual Rh from the different sites ranged from 110 to 540 g C m(-2). The maximum annual Rh occurred when the wate

Abstract Estuaries and salt marshes are important wetlands used by waterbirds during winter and migration. However, many salt-marshes have been transformed into salinas, which currently function as high-tide roosts. Since traditional salt production is no longer profitable, many salinas have been abandoned or converted into aquaculture potentially becoming less attractive to waders. In this study

The diversity and community composition of moths (both macro- and micromoths) at 32 sites, representing a wide range of habitat types (forests, grasslands, wetlands, agricultural and urban areas) within a restricted region in central Scania,southern-most Sweden, was investigated by use of light moth traps and compared with vascular plant species richness and habitat characteristics.
