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
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
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
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
Summary: Floodwater mosquitoes occur in temporary flooded areas and can cause tremendous nuisance in the near and far surroundings. In the Nedre Dalälven region in Central Sweden, mosquito control is based on application of the biological larvicide Bacillus thuringiensis israelensis (BTI) by helicopter. Precise mapping of the floodwater mosquito breeding sites, a prerequisite for successful BTI tr

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
Den digitala utvecklingen som skett de senaste årtiondena har lett till att internet idag är en nödvändighet för individer, men även samhället i stort, i västvärlden. En värld utan internet är idag otänkbar. För att kunna utnyttja internet till fullo och lyckas navigera i detta gigantiska nätverk är internetlänkar en förutsättning.

Internet, a gigantic network full of information, is today a necessity in Western societies and a world without it is unimaginable. In order to be able to navigate within the Internet and retrieve information, the usage of links is vital since it connects the information available on the Internet. The Internet user can therefor
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. The results re
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
På grund av vissa 3:12-reglers utformning och praxis på området har överlåtelser av fåmansbolag genom den sk. trädabolagsmetoden behandlats skattemässigt olika beroende på om förvärvaren av bolaget ingår i närståendekretsen eller inte. Riksdagen har genom att bifalla Prop. 2018/19:54, avsett att ändra på olikbehandlingen genom att det bl.a. införs ett nytt lagrum i lagstiftningen, 57 kap. 4 a § ILDue to the construction of some 3:12 rules and precedents from the Supreme Administrative Court, transfers of close companies through the so-called ”trädabolagsmetoden” is from a tax aspect treated differently, depending on whether the acquirer of the close company is related to the seller or not. Related persons is currently disfavoured. The Swedish Parliament has through accepting Prop. 2018/19:
Popular Abstract in Swedish Hjärnan är ett komplext system, som är uppbyggd av många olika sorters celler. Alla dessa celler har sitt ursprung i en speciell typ av cell, stamcellen. Neurala stamceller är omogna celler som har förmågan att genom delning både föröka sig själva genom att bilda fler stamceller, och ge upphov till de olika mogna celltyper som finns i hjärnan. Mycket av intresset för deThe molecular specification of neural precursor cells has been suggested to be a progressive process, with a transition from an early requirement for extrinsic signals to intrinsic mechanisms. Thus, the cells in the nervous system acquire distinct fates in response to extrinsic signals, which activate repertoires of transcription factors in a region and cell type specific manner. The studies in th
Taphonomy is the study of how different processes have affected the osteological material, from the death of the animal and forward. The purpose of the analysis is to study how taphonomic processes and fluvial activity affect the preservation of osteological material in a wetland environment, by examining the zooarchaeological material from Röekillorna Spring (Löderup parish, Scania). A quantitati
Hunnebostrand var under 1900-talet ett av Sveriges främsta stenhuggerisamhällen. Här höggs och bearbetades stenen för att sedan fraktas till platser över hela världen. På 70-talet lades stenhuggeriverksamheten i Hunnebostrand ner, men spåren efter industrin lever kvar i samhället än idag. En viktig plats i Hunnebostrand under stenhuggeriepoken var Udden. Här höggs sten från Norra Högeberg och plaThis project examines the potential design of a visitor center named ”Stenens Hus” in Hunnebostrand, Sweden. The village was a prominent stone quarrying community in the 20th century, and the quarrying industry left its mark on the town even after it was shut down in the 1970s. One important place in Hunnebostrand during this era was Udden, where stone from Norra Högeberg was quarried. The site

In order to determine a suitable working process as well as presenting a possible architectonic result of the process, a case study is carried through. A housing projekt is designed on a site i Malmö, where the commisioner is
Three well-known dynamic acidification models (MAGIC, SAFE, SMART) were applied to data sets from five Integrated Monitoring sites in Europe. The calibrated models were used in a policy-oriented framework to predict the long-term soil acidification of these background forest sites, given different scenarios of future deposition of S and N. Emphasis was put on deriving realistic site-specific scena
Active site titration and activity measurements were performed in hexane on lyophilised lipase preparations containing different amounts of phosphate buffer and lipase immobilised on porous polypropylene. Lyophilisation of Thermomyces lanuginosus lipase with large quantities of phosphate salts (200 mm) increased the specific activity fourfold, and the number of rapidly titratable active sites incr

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
