In their natural habitats, bacteria and plants can be exposed to abiotic stresses such as drought, high salt concentrations and freezing, which are factors limiting their capacity for growth and proliferation. To withstand environmental stresses, they have evolved specific stress responses. These responses include physiological adaptations, alterations in gene expression and production of protecti

Popular Abstract in Swedish Inledning: Stroke är en av de största folksjukdomarna. En patient med akut stroke behöver medicinsk omhändertagande vid en vårdenhet med specialkunskap. För att så tidigt som möjligt kunna planera omhändertagande och ta ställning till behandling är tillförlitlig diagnostik i akutskedet viktig. Cirka 20% av patienter med stroke har en blödning. Hjärnblödning diagnosticerPurpose: To compare the visualization of small ischemic brain lesions using diffusion using diffusion-weighted (DW) MRI and conventional imaging, with special regard to diagnostic efficiency. Imaging features of lesions of different ages, diagnostic limitations and technical principles were also investigated. Methods: All studies were performed with the same 1.5 T MR scanner. In the first study t

Popular Abstract in Swedish Mitt försöksmaterial utgjordes av Festuca ovina, fårsvingel, som är ett mycket vanligt gräs och tillhör familjen Poaceae. Fårsvingel är en perenn korsbefruktare och spridd över den tempererade zonen i Euroasien och Nordamerika. Släktet Festuca är uppdelat i smalbladiga svinglar, dit fårsvingel hör, och bredbladiga svinglar. Släktet Lolium, dit rajgräsen hör, är en nära Festuca ovina, sheep's fescue is a widely distributed perennial outbreeder that belongs to the grass family Poaceae and is very common in the northern temperate zone. The genus Festuca s.l. is partitioned into fine-leaved fescues to which F. ovina belongs, and broad-leaved fescues to which the genus Lolium is a close relative. Wide crosses within the Festuca-Lolium complex often yield fertile hybr

The objective of this study was to describe environmental barriers and investigate the nature of accessibility problems in housing among single-living, very old people (N = 1,150) in urban regions in three European countries (Sweden, Germany, Latvia), in a one-year perspective. A specific feature of this study is the explicit conceptual differentiation between environmental barriers and accessibil

The accuracy of NOAA AVHRR NDVI maximum value composites can be poor due to interference from several sources, including cloud cover. The objectives of this paper are; 1. to accurately quantify noise in this imagery over Africa using geostatistics, and 2. to test four compositing techniques that may be able to reduce this noise. The nugget of the variogram model is used to compute standardized noi

This book chapter is a part of a memory study of the reception of Lucy Maud Montgomery's books in Sweden. Two reading memories of Montgomery's Emily of New Moon are discussed in this chapter.
