HIV/AIDS - Epidemi som påverkar tillväxt?

This study is motivated by the low GDP per capita growth and high rates of HIV/AIDS in sub-Saharan Africa. HIV/AIDS has according to the literature severe impact on both economic and socioeconomic variables, such as lowering the work force and reducing the demand for education. HIV and poverty implies a vicious cycle, since poverty leads to more sensitiveness for the disease, and the disease leads

Vi trivs bäst i öppna landskap, eller? En utvärdering av förändringen från cellkontor till öppna kontorslandskap hos Skatteverket i Helsingborg

Skatteverkets Helsingborgskontor genomgick för ungefär ett år sedan en organisationsförändring i form av ett byte från arbete i cellkontor till arbete i öppna kontorslandskap i en annan byggnad. Detta gjordes på grund av att det uppstod problem i den tidigare byggnaden. Denna utvärdering syftade till att undersöka hur medarbetare och sektionschefer upplever sig ha påverkats av förändringen i konto

Motpolen till populärkulturen

Att börja bli vuxen är inte alltid enkelt och det gör att en del problem uppstår. Genom media får ungdomar en bild av samhället om hur de förväntas vara, en bild som inte alltid är korrekt. Syftet med denna analys var därför att få fram hur vuxenvärlden som en motpol till övriga medier vill förmedla en mer korrekt bild till unga mellan 8-14 år. För att analysera hur denna motpol förmedlar olika bu

European Court of Justice; Hur kan dess utveckling till en konstitutionsdomstol förstås? En förklarande uppsats utifrån tre förklaringsmodeller

The thesis aims to explain to the development of the European Court of Justice into a constitutional court. The transformation of ECJ into a de facto constitutional court is studied using three perspectives, constitutionalism, neofunctionalism and by a judicial activism perspective. By using the three mentioned theories it’s made possible to understand the court’s development from a political and

Det preventiva kriget - Ett rättfärdigt ont? En analys av Kriget mot terrorismen som preventivt krig

The purpose of this thesis is to inspect the very foundations of the preventive war, in form of its moral justification. In terms of exploring that fairness, the War on terror will be used for challenging the matter of justification as well as demonstrating a new and transformed way of referring to preventive aggression, as have been done by the Bush-administration since September 11. The methods

I jakten på rättvisa

In northern Uganda, a war between the Lord’s Resistance Army (LRA) and governmnet troops has raged for more than twenty years. In this conflict, the civilian population has been made a target and subjected to mass scale torture, mutilation and murder. Almost two million people have been forced to flee their homes to reside in government protected camps for Internally Displaced Persons. In these ca

Facebook, mitt bästa jag varje dag - En kvalitativ studie om redigering av den personliga framställningen på Facebook, ur ett dramaturgiskt perspektiv

Denna studie är en kvalitativ undersökning som ämnar studera huruvida användare kan redigera sin självpresentation på communitysiten Facebook. Syftet med studien är att utforska hur individer kan lägga upp strategier för sin självpresentation och vilka konsekvenser detta kan medföra. Uppsatsen kommer även att behandla huruvida individer på Facebook hanterar de olika roller de innehar i situationen

Think outside the box - En studie om hur varumärkesidentitet skapas och förmedlas

Problembeskrivning: Ett företags varumärkesidentitet är den bild av företaget som de önskar att deras konsumenter och omgivning ska uppfatta. Den bild företaget vill förmedla stämmer dock inte alltid överens med den bild som faktiskt förmedlas. Större delen av tidigare forskning har skilt på hur varumärkesidentitet skapas och förmedlas. Vi ser emellertid ett tydligt samband mellan det interna skap

The relationships between tropical Pacific and Atlantic SST and northeast Brazil monthly precipitation

The monthly patterns of northest Brazil (NEB) precipitation are analyzed in relation to sea surface temperature (SST) in the tropical Pacific and Atlantic Oceans, using singular value decomposition. It is found that the relationships between precipitation and SST in both basins vary considerably throughout the rainy season (February-May). In January, equatorial Pacific SST is weakly correlated wit

Regionalization and spatial properties of Ceará State rainfall in northeast Brazil

The overall daily rainfall pattern of Ceará for 19 years, 1974-1992, was analyzed in terms of physiography and atmospheric circulation. This information was used to suggest a regionalization of the state's rainfall into homogeneous areas. The three large-scale precipitation mechanisms (Intertropical Convergence Zone, cold fronts, and upper air vortices) interact and create a certain rainfall patte

Lactic acid bacteria : From starter cultures to producers of chemicals

Lactic acid bacteria constitute a diverse group of industrially significant, safe microorganisms that are primarily used as starter cultures and probiotics, and are also being developed as production systems in industrial biotechnology for biocatalysis and transformation of renewable feedstocks to commodity- and high-value chemicals, and health products. Development of strains, which was initially

Impacts of silicon on biogeochemical cycles of carbon and nutrients in croplands

Crop harvesting and residue removal from croplands often result in imbalanced biogeochemical cycles of carbon and nutrients in croplands, putting forward an austere challenge to sustainable agricultural production. As a beneficial element, silicon (Si) has multiple eco-physiological functions, which could help crops to acclimatize their unfavorable habitats. Although many studies have reported tha

Microspectroscopy (μFTIR) reveals co-localization of lipid oxidation and amyloid plaques in human Alzheimer disease brains

Amyloid peptides are the main component of one of the characteristic pathological hallmarks of Alzheimer's disease (AD): senile plaques. According to the amyloid cascade hypothesis, amyloid peptides may play a central role in the sequence of events that leads to neurodegeneration. However, there are other factors, such as oxidative stress, that may be crucial for the development of the disease. In

Non-pharmacological Effects in Switching Medication : The Nocebo Effect in Switching from Originator to Biosimilar Agent

The nocebo effect is defined as the incitement or the worsening of symptoms induced by any negative attitude from non-pharmacological therapeutic intervention, sham, or active therapies. When a patient anticipates a negative effect associated with an intervention, medication or change in medication, they may then experience either an increase in this effect or experience it de novo. Although less

Effect of poly(propylene imine) glycodendrimers on β-amyloid aggregation in vitro and in APP/PS1 transgenic mice, as a model of brain amyloid deposition and Alzheimer's disease

Poly(propylene imine) (PPI) glycodendrimers are promising candidates as drug carriers and antiamyloidogenic and antiprionic agents. In this study the anti-β-amyloid capacity of PPI glycodendrimers of the fourth and fifth generations was investigated in vitro and in vivo. We assessed distinct PPI glycodendrimers including G4mDS and G5mDS, with electroneutral maltose shell, and G4mOS and G4m-IIIOS,

Dense shell glycodendrimers as potential nontoxic anti-amyloidogenic agents in Alzheimer's disease. Amyloid-dendrimer aggregates morphology and cell toxicity

Dendrimers have been proved to interact with amyloids, although most of dendrimers assayed in amyloidogenic systems are toxic to cells. The development of glycodendrimers, poly(propyleneimine) (PPI) dendrimers decorated with maltose (Mal), represents the possibility of using dendrimers with a low intrinsic toxicity. In the present paper we show that fourth (PPI-G4-Mal) and fifth (PPI-G5-Mal) gener

Granular non-fibrillar aggregates and toxicity in Alzheimer's disease

Granular non-fibrillar aggregates (GNAs) are identified as possible toxic species in Alzheimer's disease. GNAs form on the surface of negatively charged biological membranes and as a consequence of an acidic environment, off the polymerization pathway at neutral pH. Aβ (1-40) GNAs disturb the bilayer structure of model membranes and seem to be more toxic to cells with negatively charged membranes
