Vision is an important source of information for many animals. The lens plays a central role in the visual pathway and hence the ecology of these animals. Fish have spherically shaped crystalline lenses that contain a gradient of refractive index. Like all refracting elements, lens performance depends on the wavelength of the refracted light. This wavelength dependent focusing leads to chromatic a
A sustainable treatment of organic wastes, generation of renewable energy, reduction of green house gas emissions, limiting the eutrophication and closing the nutrient cycles are several environmental challenges for which anaerobic digestion may be a suitable solution. There is today a large amount of available organic waste materials that could serve as potential feedstock for biogas production.
The human genome contains genetic elements which are more or less similar to infectious retroviruses. These are called human endogenous retroviruses (HERVs) and are thought to be remnants of infections in the primate lineage. Most of them have been inserted 10 to 60 million years ago but have at different time points spread in the genome via intracellular retrotransposition and make up as much as
Fire dynamics in multi-room compartments are explored in this thesis and new methods to study conditions in rooms adjacent to the room of fire origin are presented. Simple and transparent engineering methods can create good possibilities for understanding different complex phenomena present in fire science. Such methods can also be used in the design process in order to perform rough estimates bef
The external ventricular drain (EVD) is an important instrument in the management of neuro-intensive care patients through its ability to meassure intracranial pressure and to treat increased intracranial pressure by drainage of cerebrospinal fluid (CSF). However, EVDs are associated with the risk of external ventricular drain related infection (EVDRI). EVDRI diagnosis is challenging as symtoms an
Nitric oxide synthase (NOS) activity was studied in cytosolic and particulate fractions in reproductive organs from rabbit (uterus and vagina) and rat (uterus, vagina and cervix). NOS was found predominantly in cytosolic fractions in all tissues and the activity of NOS in both fractions was highly Ca2+ dependent. NOS activity in vagina and cervix were much higher (3-6-fold) than in the uterus. Est

Their nests are often aggregated in groups of two to eight nests. Such aggregated nesting may indicate the existence of group territories,

New institutionalist approaches are inherently weak at accounting for institutional change. In this book, social network analysis is proposed as a key to institutional change. The social network perspective focuses emergent patterns of interpersonal interaction and the resulting ties of interpersonal trust. As a complement and contrast to both March and Olsen’s influential new institutionalist "lo
Extant research within the entrepreneurial marketing field has typically focused on the migration away from traditional marketing concepts while mostly ignoring the inclusion of branding as a fundamental principle of marketing. This paper is specifically interested in the often overlooked element of a young firm’s ability (or lack thereof) to control its brand and brand identity as perceived by it
Popular science Biogenic volatile organic compounds (BVOCs) are a versatile group of non-methane hydrocarbons (chemical compounds made of carbon and hydrogen) emitted by vegetation. The most common BVOCs from plants are some chemical compounds like isoprene, monoterpenes and sesquiterpenes. BVOCs are involved in plant growth, reproduction and defense mechanisms. Besides, BVOC play an important rol
My identity in the eyes of myself and others [translated title]. The purpose of this study was to examine how teenage girls experience their identities and how it is constructed and influenced by external factors. It was also an attempt to illustrate how mass media and social media like Facebook and blogs can be elements in the construction of identities. Berger and Luckmann‟s social construction
The two genetically related human lentiviruses known today, HIV-1 (which is pandemic) and HIV-2 (which mainly is confined to West Africa), are the causative agents of AIDS. Progressive immune dysfunction and AIDS develop in most cases of untreated HIV-1 infection, but only in approximately 25-30% of HIV-2 infected individuals. The V1-V3 region of the HIV-1 env gp120 is important for HIV-1 corecept
Background: A prognostic marker should provide information about course and outcome of disease, e.g. predict time to a given endpoint or rate of progression due to disease in patients or subgroups of patients. Prognostic markers could be targeted to apply during the entire clinical course or just during distinct stages of the disease. Aim: The aim of this thesis is to identify, review and qualif
L-DOPA pharmacotherapy in Parkinson’s disease (PD) is associated with adverse effects occurring after a few years of treatment. Among these, dyskinesia (abnormal involuntary movements) is particularly common and potentially disabling. The causes behind dyskinesia are not completely understood, but intense research has identified a number of neuronal alterations associated with L-DOPA-induced dyski
In this thesis, the main focus has been on the childhood cancer neuroblastoma, one of the most common and lethal childhood tumours. Neuroblastoma has througout the years continued to be a clinical and biological enigma. Our first focus was on one of the most important biological risk factors in neuroblastoma -- amplification of the oncogene MYCN in the tumour cells. Because amplified MYCN typical
Abstract The scaphoid is the most commonly fractured carpal bone. The diagnosis is difficult and untreated the long-term results are poor. Approximately 10% do not unite even if they are treated properly. The aim of this thesis was to study scaphoid fracture epidemiology, diagnosis and treatment. During a four-year period (2004-03-01 to 2008-02-28) all patients attending the Emergency Department a
