Integrated pest management (IPM) is an important tool for sustainable crop production. IPM includes a diversity of methods, e.g., the use of biological control agents (BCAs) for disease control or growth promotion. While there is an increasing interest in the use of BCAs, less is known about their environmental costs and benefits on wild species, such as wild crop relatives. For example, a BCA may
The important role of fire in regulating vegetation community composition and contributions to emissions of greenhouse gases and aerosols make it a critical component of dynamic global vegetation models and Earth system models. Over two decades of development, a wide variety of model structures and mechanisms have been designed and incorporated into global fire models, which have been linked to di
Den växande efterfrågan på hållbar och miljövänlig elproduktion, tillsammans med globala osäkerheter, understryker behovet för nationer att uppnå självförsörjande produktion av el. Kärnkraft, som står för cirka 30% av Sveriges elproduktion, spelar en avgörande roll i att leverera fossilfri el. Eftersom många kärnkraftverk närmar sig slutet av sin planerade livslängd är det avgörande att förlänga dThe growing demand for sustainable electricity production, coupled with global uncertainties, highlights the need for nations to achieve self-sufficiency in producing electricity. Nuclear power, which provides around 30% of Sweden's electricity, plays a critical role in delivering fossil-free electricity. As many nuclear plants are near the end of their designated lifespans, extending their operat
roduction of biomass for bioenergy on marginal land has been promoted to decrease the use of non-renewable energy without competing with food production. Previous estimates of marginal land and abandoned farmland in Sweden available for bioenergy production are based on general statistics and assumptions but lack in-depth analyses of potential alternative land-use values.

In post-peace agreement Colombia, everyone declared war on the forest. In the Putumayo region, these wars take their own particular forms. Scientifically, the Putumayo is described as an Andean-Amazonic rainforest. For the indigenous and local inhabitants of the Putumayo, it is the Andean-Amazonic selva. We present three wars on the forest with material and discursive specificities and critically
Dispersal barriers have demographic, evolutionary and ecosystem-wide consequences. With ongoing changes in the environment, it is likely that some dispersal barriers will disappear while others will appear, and it is crucial to understand these dynamics to forecast species distributions and adaptive potential. Here we review recent literature on the ecological and evolutionary aspects of dispersal
Abstract: Patients with colorectal cancer may lack information about the disease and treatment. In 2017, a group consultation before start of surgery was introduced at a university hospital in western Sweden to inform about the disease, treatment, and ongoing scientific studies. The primary aim of this study was to explore the experience of the patients attending the group consultation. Based on s
For many years, prostate cancer early detection was a straightforward matter of recommending biopsy to all men with an elevated prostate-specific antigen (PSA). This is perhaps best evidenced by the European Randomized Trial of Screening for Prostate Cancer, where an automatic biopsy is specified in the protocol and close to 90% of men with a PSA ≥3.0 ng/mL were biopsied [1]. Starting around 2010,
Zeaxanthin, a carotenoid in the xanthophyll cycle, has been suggested to play a role in the protection against photodestruction. We have studied the importance of the parameters involved in zeaxanthin formation by comparing spinach plants grown in low light (100 to 250 mol m-2 s-1) to plants transferred to high light (950 mol m-2 s-1). Different parameters were followed for a total of 11 days. Our
The overall aim of this thesis is to elaborate on the art of living with a traumatic spinal cord injury (SCI) in its relation to resources and norms in Swedish society. The thesis originates in part from a prevalence group of SCI individuals and is based on four studies. One is longitudinal and register based, and one is interview based. A paper on “ethics in the making” elaborates how general ver
A new, cyclodextrin glycosyltransferase (CGTase) from an alkaliphilic B. agaradhaerens strain LS-3C, isolated front an Ethiopian soda lake. was purified up to 43-fold by starch adsorption with a yield of 50%. The enzyme was a monomer with an estimated molecular weight of 110 kDa, representing the largest Bacillus CGTase reported so far. The isoelectric point (pI) of the enzyme was 6.9. The CGTase
OBJECTIVE: To measure intracellular and tissue pH in periarticular soft tissue during different phases of antigen induced arthritis in the rat. METHODS: pH was calculated using the following values: (1) the distribution of [14C]-dimethyl-oxazolidinedione; (2) the total tissue water and the extracellular space water volume, which was measured as [14C]-sucrose distribution in nephrectomized rats. Ex
The aim of the user related assessment was to study perceived advantages, disadvantages, usefulness, trust, acceptance, willingness to have and pay for the driver assistance system: Continuous Support & Curve Speed Control developed by FFA within the framework of the SECONDS subproject. Due to restrictions in driving in real traffic, assessment activities were limited to driving on a test trac
The aim of the project has been to elucidate molecular events leading to amyloidosis in Hereditary Cystatin C Amyloid Angiopathy (HCCAA) patients, to enable simple diagnosis of the disease and with the ultimate goal to understand the amyloid formation process in detail, in order to develop inhibitors to the process. At the DNA level, a point mutation segregating with HCCAA was identified in the cy
Given the anthropometric differences between men and women and previous evidence of sex-difference in genetic effects, we conducted a genome-wide search for sexually dimorphic associations with height, weight, body mass index, waist circumference, hip circumference, and waist-to-hip-ratio (133,723 individuals) and took forward 348 SNPs into follow-up (additional 137,052 individuals) in a total of
Popular Abstract in Swedish Moder natur har i tusentals år varit en fantastisk källa till biologiskt aktiva substanser mänskligheten utnyttjat för att bota och förebygga sjukdomar. Från början användes olika beredningar och avkok från växter funna i närområdet som erfarenheten visat hade effekt mot åkomman man ville behandla. Detta har i modern tid utvecklats till att vi idag på ett systematiskt sIn 2005 two research groups independently reported the isolation of a series of structurally intriguing C-19 terpenolides from the plants Thapsia transtagana and Thapsia garganica. The compounds were shown to be potent inhibitors of the sarco/endoplasmic reticulum Ca2+-ATPases. The interesting biological properties and the unique structural characteristics of the transtaganolides/basiliolides (the
Spatial and temporal variations in polychlorinated biphenyl (PCB) concentrations were studied in precipitation at 11 sampling-sites over a period of 1 year and compared with PCB concentrations in the air. The study was carried out in a region of southern Sweden approximately 11 000 km2 in area. The PCB concentration in precipitation ranged between 1.18 and 81.4 ng l(-1). Two of the sampling sites
The oxidation of free DHA, DHA mixed with PC, and DHA incorporated into PC, PE, or TG was evaluated to determine which lipid provided DHA with the best protection against oxidation. DHA was either situated at the sn-1 position, sn-2 position, or both positions of the phospholipid, whereas the TG contained DHA at all positions. All lipids were incubated as bulk lipids, in chloroform, or as an emuls
Kai Söderhjelm (b. 1918 in Helsinki, d. 1996 in Gothenburg) belonged to a Finland-Swedish cultural family, and was for many years an important and valuable figure in the intellectual life of Sweden. Söderhjelm’s authorship follows the same clear thematic lines from his first book, Rid mot nordväst (1948; Ride to the northwest), to his last, Okänt land (1993; Unknown land). These themes are peace,
