This thesis analyses the relationship between sustainability transformations and grassroots movements in Monteverde, Costa Rica. The focus is toward understanding the influence of community-based initiatives on transformations that have sustainability as a goal, due to their potential for shaping society and addressing challenges such as climate change. The study also examines the emergence and de

3D city models are valuable tools for visualization and analytical purposes in the urban environment. A popular format for city models is CityGML, an open data model that can be used for storage and exchange of 3D city models. However, using city models based on CityGML has appeared to be a challenge as there is a limited number of software applications that are able to read them. Complexity in Ci

Det här examensarbetet beskriver ett projekt som har genomförts med Phasor Solutions Ltd om att simulera olika fel som kan uppstå i en sfärisk närfälts skanner (SNFS). En SNFS är ett komplicerat mätsystem som gör det möjligt att göra exakta mätningar för en halvsfär runt antennen som testas. Då frekvenserna som används i skannern är höga, geometrin är komplicerad och att transformation mellan närfThis thesis covers the work that has been carried out with Phasor Solutions Ltd on simulating possible errors in their spherical near field scanner (SNFS). A SNFS is a scanner that enables exact measurement to be taken in a complete hemisphere around an antenna under testing (AUT). Due to the high frequency, complex geometries and the fact that the transformation between near-field and far-field d

Lake sediments have lately been explored as a 10Be archive, complementing previous research on ice cores and marine sediments. 10Be is an important proxy as it can be used to study past solar activity, a factor which affects the climate. Where other methods studying solar activity only cover a brief period of history, 10Be has the potential to go further back in time. The concentrations of 10Be st

Parkinson´s Disease is the second most common neurodegenerative disease. Only a small number of cases appear to be caused by genetic mutations, meaning most cases arise due to unknown mechanisms. While there are reported to be multiple causes of the disease, what links all cases is a small protein called α-synuclein whose aggregation appears to correlate to the pathology and progression of the dis

The demand for renewable energy is constantly increasing and in order to compete with other sources of energy the wind energy output has to increase. The power output from wind turbines are highly dependent on the swept radius of rotor blades. Increasing the length of the rotor blades will increase the weight of the blades, resulting in higher demands of the structural performance, but also introd

During free behaviors animals often experience lateral forces, such as collisions with obstacles or interactions with other animals. We studied postural reactions to lateral pulses of force (pushes) in the cat during standing and walking. During standing, a push applied to the hip region caused a lateral deviation of the caudal trunk, followed by a return to the initial position. The corrective hi

Selective vulnerability in the nervous system refers to the fact that subpopulations of neurons in different brain systems may be more or less prone to abnormal function or death in response to specific types of pathological states or injury. The concept has been used extensively as a potential way of explaining differences in degeneration patterns and the clinical presentation of different neurod

Aim: To study self-esteem in clinical sample of obese children and adolescents. Methods: Obese children and adolescents aged 8-19 years (n = 107, mean age 13.2 years, mean BMI 32.5 [range 22.3-50.6], mean BMI z-score 3.22 [range 2.19-4.79]; 50 boys and 57 girls) were referred for treatment of primary obesity. Self-esteem was measured with a validated psychological test with five subscales: physica

The Lande g(J) factors in the 6snd(1,3)D(2) sequences as well as states from the perturbing configurations of neutral Ytterbium have been measured by time-resolved fluorescence spectroscopy. Strong singlet-triplet mixing effects were observed. The g(J) factors were measured using the Zeeman quantum-beat technique following step-wise laser excitation. The experiment provided new data for checking t

BACKGROUND AND AIMS: Although increasing evidence suggests involvement of the distal airway in all stages of asthma, it is not known whether structural changes (defined as airway remodelling) occur in the distal airways of subjects with mild asthma and those with atopy. The aim of this study was to compare control subjects and those with mild asthma in relation to fibroblast phenotypes and remodel

The Flinders Sensitive Line (FSL) rat is a genetic animal model of depression that displays characteristics similar to those of depressed patients including lower body weight, decreased appetite and reduced REM sleep latency. Hypothalamic neuropeptides such as orexin/hypocretin, melanin-concentrating hormone (MCH) and cocaine and amphetamine regulated transcript (CART), that are involved in the re

Observational studies show an association between ferritin and type 2 diabetes (T2D), suggesting a role of high iron stores in T2D development. However, ferritin is influenced by factors other than iron stores, which is less the case for other biomarkers of iron metabolism. We investigate associations of ferritin, transferrin saturation (TSAT), serum iron, and transferrin with T2D incidence to cla

Subcellular localization of protein kinase often plays an important role in determining its activity and specificity. Protein kinase C (PKC), a family of multi-gene protein kinases has long been known to be translocated to the particular cellular compartments in response to DAG or its analog phorbol esters. We used C-terminal green fluorescent protein (GFP) fusion proteins of PKC isoforms to visua

Aims and objectives. To describe stroke patients' perceptions of their participation in the discharge planning process and identify correlates of perceived participation. Background. Patients have the right to participate in discharge planning, but earlier research has shown that they are often dissatisfied with the information they receive and their involvement in goal-setting during discharge pl

AIMS/HYPOTHESIS: About 35% of individuals with type 2 diabetes develop persistent albuminuria, lose renal function, and are at increased risk for microvascular complications like diabetic nephropathy. Recent genome-wide association studies have identified the uromodulin locus (UMOD), encoding the most common protein in human urine to be associated with hypertension and also with chronic kidney dis
