The use of topographical data in hydrological and agricultural applications has increased with GPS data availability and the concept of precision agriculture. This thesis investigates the relationships between topography and in one case simulated soil moisture and in the other case yield. The yield was recorded with a new optical sensor, which uses a digital camera to detect objects and records th
Around 70,000 osteoporosis-related fractures occur in Sweden annually and approximately half of the women in western world will sustain a fragility fracture after the age of 50 years. Fracture preventive efforts require the identification of individuals who are at high risk. Biochemical markers of bone turnover (BTMs) have shown some degree of fracture predictability. There is also a correlation b
Understanding the mechanisms of complex polygenic diseases like type 2 diabetes (T2D) is as complex as their nature. Cellular processes involved in glucose homeostasis need high and reliable energy supply. Mitochondria are the major energy producers in mammalian cells. Since majority of the mitochondrial genes are encoded by the nuclear genome, a tightly regulated and coordinated nuclear-mitochond
This dissertation examines how young people with Kurdish backgrounds form their identity in Sweden with regards to processes of inclusion and exclusion. It also sheds light on the ways these young people deal with ethnic discrimination and racism. Further, the study outlines the importance of these social processes for the discipline of social work and the ways social workers can work with disadva
We have measured the uptake capacity of nitrogen (N) and potassium (K) from different soil depths by injecting N-15 and caesium (Cs; as an analogue to K) at 5 and 50 cm soil depth and analysing the recovery of these markers in foliage and buds. The study was performed in monocultures of 40-year-old pedunculate oak (Quercus robur), European beech (Fagus sylvatica) and Norway spruce (Picea abies (L.
The quinoline-3-carboxamides (Q compounds) are a family of small molecules that ameliorate various types of murine inflammatory autoimmune disease. One such compound has also demonstrated anti-tumor effects in murine tumor models. Several Q compounds have reached clinical trials and one compound, laquinimod, is currently in phase III clinical trial for relapsing-remitting multiple sclerosis. The Q
BACKGROUND: Postmenopausal hormone therapy (HRT) and oral contraceptive (OC) use have in several studies been reported to be associated with a decreased colorectal cancer (CRC) risk. However, data on the association between HRT and OC and risk of different clinicopathological and molecular subsets of CRC are lacking. The aim of this molecular pathological epidemiology study was therefore to evalua
BACKGROUND: Gonadotropin-releasing hormone (GnRH) antagonists have been reported to have beneficial effects on lower urinary tract symptoms in patients with benign prostatic hyperplasia. OBJECTIVE: Our aim was to investigate the effects of ganirelix, a GnRH receptor antagonist, on bladder function and detrusor overactivity (DO) in female rats. DESIGN, SETTING, AND PARTICIPANTS: Female Sprague-Dawl
The effect of plant species diversity on productivity and competitive ability was studied in an experiment carried out simultaneously in five European countries: Czech Republic (CZ), the Netherlands (NL), Sweden (SE), Spain (SP), and United Kingdom (UK). The aim was to separate the 'chance' or 'sampling effect' (increasing the number of sown species increases the probability that a species able 't
1 Plant species differ in their capacity to influence soil organic matter, soil nutrient availability and the composition of soil microbial communities. Their influences on soil properties result in net positive or negative feedback effects, which influence plant performance and plant community composition. 2 For two grassland systems, one on a sandy soil in the Netherlands and one on a chalk soi
Abstract in UndeterminedThis study deals with a current problem of urban human-biometeorology on the micro-scale, which becomes more important due to the future increase of severe summer heat in Central Europe. The impact of street design parameters on the thermal comfort of citizens is analysed in an experimental way for typical summer conditions in Central Europe. The investigation is focused on
Popular Abstract in Swedish Benskörhet (osteoporos) är en sjukdom som karaktäriseras av minskad mängd benmassa och försämrad benkvalitet. Benskörhet leder till en ökad risk för frakturer. Förekomsten av benskörhet har fördubblats under de senaste decennierna. Upp till en tiondel av alla män och en fjärdedel av alla kvinnor lider av sjukdomen. Ökningen av benskörhet i samhället kan delvis förklaras
Studies of the long-lived anthropogenic radionuclides 99Tc, 237Np, 239Pu and 240Pu were performed in marine and terrestrial areas contaminated by different accidental and controlled releases of radioactive materials. The three main sources discussed in this thesis are nuclear weapons tests, nuclear reprocessing plants and the Chernobyl accident. Results are mainly based on measurements of environm
The dissertation can be divided into two parts, the first of which is a detailed analysis of three excavations concerning Mellanbyn in southern Malmö. In the second part I study the more general development of society, relating Mellanbyn to the surrounding area as well as to the region as a whole during Late Bronze Age and the Early Iron Age. The aim can be summed up as being to study the developm
Popular Abstract in Swedish I dag används cellhämmande medel, cytostatika, ofta i kombination med andra metoder för behandling av vissa typer av cancer. Cytostatika kan bota t.ex. leukemi, testikel- och lymfkörtelcancer, eller lindra symtomen och förlänga livet vid t.ex. småcellig lungcancer. En grupp av cytostatika utgörs av metallkomplex där metallen är platina (Pt). Upptäckten av en sådan förenThe kinetics and mechanism for interactions of the anticancer active platinum(II) complexes cis-[PtCl2(NH3)2)], cis-[PtCl2(NH3)(c-C6H11NH2)], and trans-[PtCl2-(NH3)(quinoline)] with DNA have been studied using a combination of HPLC, circular dichroism (CD), UV/vis spectroscopy, and differential scanning calorimetry (DSC). Reactions of the monoaqua forms (charge = +1) of these complexes with single
Popular Abstract in English All living things somehow communicate with each other. Cell-to-cell communication, or signalling, occurs on the molecular level, regulating the body’s activities and coordinating various cell actions and is thereby valuable for realizing cell as well as system functions. Errors in the cellular transferred information may induce diseases such as cancer and autoimmune disGlypicans are multifunctional cell surface heparan sulphate proteoglycans co-regulating numerous signalling pathways, and are thereby involved in the control of cellular division, differentiation, and morphogenesis. The heparan sulphate (HS) chains are responsible for many of those biological functions; nevertheless recent studies suggest functional roles for the glypican core proteins in mediatin
Chancroid caused by Haemophilus ducreyi, has been described as a significantly predisposing factor of HIV heterosexual transmission in an endemic region of both diseases. Antibiotic resistances are extensively found in H. ducreyi and many of the resistances are due to the presence of resistance plasmids. A high tendency of drug resistances has commonly been found among isolates derived in Thailan
