Hur bryts apo-katalas ned i bakterien Enterococcus faecalis? Väteperoxid, H2O2, är ett kemiskt ämne som används som blekningsmedel för allt från papper till hår. Det används också i somliga bränslen och desinfektionsmedel. Celler producerar vanligtvis väteperoxid som en biprodukt av sin metabolism. I celler ställer väteperoxid till potentiella problem då ämnet kan orsaka bildning av ”fria radikalCatalase is a heme-containing homo-tetrameric enzyme that catalyzes the degradation of hydrogen peroxide. Apo-catalase is in the bacterium Enterococcus faecalis produced also in the absence of heme. In this work I have enriched and studied proteolytic activity causing apo-catalase degradation in stationary growth phase E. faecalis cells. The activity was enriched from soluble cell free extract of

The possibility of improving indoor climate in residential buildings in Botswana was examined as the foundation of this Master’s Thesis. Initially articles were studied to gain understanding of previous research in the field as well as to gain understanding of local energy related conditions. Furthermore, a software called TRNSYS was thoroughly studied as this was found to be a powerful tool able

Torr jord ger ifrån sig mer koldioxid när det regnar När det regnar på torr jord bildas under en kort tid mycket mer koldioxid än vad jorden vanligtvis avger. Detta fenomen har varit känt sen 1950-talet och kallas enkelt för torkning och återfuktning. Även om vi vet att det sker så vet vi väldigt lite om varför det sker. Till en början trodde man att det hade att göra med en ökad aktivitet hos ma

This thesis analyses ten indepth interviews on domestic workers, class and gender roles with ten young, politically inclined and often adamantly feminist women towards the upper end of the Indian class spectrum. It aims to deepen the understanding of employerworker relations and gendered domestic roles in contemporary Indian households. Previous literature on the middletoupper class employers of d

The leading internet companies display a dominance in world markets unparalleled in many industries. Despite this, China remains a hurdle no major internet company has been able to overcome. The role of government, culture and strategic decisions are all posited as potential explanatory factors. This paper concentrates on the significance of guanxi as an explanatory factor, linking its utilisation

How will baby fish react to global warming? As most people have been aware of, global warming is just one of many consequences of climate change and increasing CO2-levels in the atmosphere. The oceans are experts at absorbing energy, which makes the ocean temperature rise. In many parts of the world, especially Australia, the sea surface temperatures (SSTs) are increasing rapidly today. This is e

This master thesis seeks to convey an alternative approach for studying post-soviet civil society, with a particular focus on Azerbaijan. It rejects utilization of mainstream and overused liberal-democratic approach to civil society, which has been a predominant contextual framework for growing body of literature on civil society’s contribution to democracy in the post-communist space. By using Gr

Malaria is an infectious disease caused by the protozoan of the genus Plasmodium. It is a major problem in third-world countries, with hundreds of millions of infections and millions of fatalities annually. The extreme challenge in malaria management is the resistance of parasites to traditional chemotherapies like chloroquine and artemisinin. Plasmodium falciparum dihydroorotate dehydrogenase (Pf

The aims of this study are two-fold. Firstly, the purpose is to discuss consultancy companies as actors in private-public partnerships (PPPs) in development assistance. Secondly, the study aims to explore the actions of consultancy companies in partnership with country-beneficiaries. The theoretical base of this study is grounded in debates about PPPs in development and theoretical accounts of pos

Sepsis is a severe and often lethal inflammatory response to an infection. During sepsis the cells and organs no longer function as they should because of the intense immune response. Some of the cell dysfunction may be because of an important “sugar layer” known as the glycocalyx. In this study, we determined whether an inflammatory protein, heparin binding protein (HBP), might contribute to the

Approximately a quarter of a million women are diagnosed with ovarian cancer annually worldwide. Identifying the genes involved may ultimately lead to the development of corrective and preventive measures to fight this type of cancer. Next Generation Sequencing is a technology that can reveal the genes central to cancer initiation and development, however the analysis of the data is problematic du

This thesis investigates the interpretation of metaphorical expressions in Dante’s famous Inferno and how this may be motivated through the use of codes and inference. Based on Coseriu’s Integral Linguistics (Coseriu, 1985), metaphorical expressions can be divided depending on the kind of knowledge that is required to interpret them. The first level is the universal level where metaphors can be in

Sex chromosome evolution is a fascinating research topic because sex chromosomes provide a snapshot of evolution in many different lineages. Sex chromosomes often cease to recombine and therefore degenerate, and have also often been reshuffled during their evolution from autosomes. It has been discovered that within Sylvioidea passerine species half of chromosome 4a has translocated and fused with

Studien utgår från förekomsten av våld i samhället och våld som ett pedagogiskt problem. Syftet är att undersöka ung-domars och lärares attityder till fenomenet våld för att kunna anpassa preventiva åtgärder därefter. I studien an-vänds en kvalitativ ansats för att kartlägga hur elever och lärare på en skola uppfattar och beskriver våld, dess orsaker och möjligheterna att förebygga det. Datainsaml

The national day of Australia is Australia Day; a contentious public holiday that sparks a national debate on identity and multiculturalism every year. There are many different narratives that make up the Australian story, which encapsulates Australia’s diverse and multicultural history. Media plays a pivotal role in the representation of the national narrative; however, evidence of systemic power

In 2012 prostate cancer was the second most common cancer diagnose for men. The diagnosis is confirmed by pathologists doing ocular inspection of prostate biopsies and the specimens are classified according to the Gleason grading system. The main goal of this thesis is to automate the classification using Convolutional Neural Networks (CNN). With the introduction of Convolutional Neural Networks the

SAMMANFATTNING Apply Emtunga är ett företag som saknar struktur gällande sin orderprocess. Examensarbetets syfte är därför att kartlägga företagets orderprocess samt klarlägga vilka problem som uppstår i samband med denna. Examensarbetet ämnar därmed svara på följande tre frågor: - hur orderprocessen ser ut, vilka problem som kan identifieras i samband med orderprocessen samt vilka förslag på åtg

Sammanfattning Syftet med denna uppsats är att undersöka om, och i så fall vilken, betydelse mångfald har när en plats marknadsför sig mot dess invånare. Då vårt studieobjekt är Helsingborgs stad har vi applicerat våra teoretiska resonemang på huruvida en organisation använder mångfald i marknadsföring för att främja goda relationer mellan kommunen och invånarna. För att undersöka detta har vi gj

De nickel-kadmiumbatterier som tillverkas vid Saft AB i Oskarshamn är uppladdningsbara och används vanligen som backup för strömförsörjning på sjukhus, flygplatser och till och med för hela städer. Ett problem för nickel-kadmiumbatterier är upplösning av kadmiumhydroxid, det aktiva materialet i kadmiumelektroden. Utöver förlust av aktivt material kan det upplösta materialet bilda ett tunt lager påIn this project, the properties of Cd(OH)2 in alkaline solution were studied. The processes of oxidation and reduction for Cd(OH)2 in alkaline solution are very complex and even though many studies have been done on the subject, it is not completely understood yet. It is from a Ni-Cd battery point of view, important to understand these processes to prevent loss of active material. The Cd-electrode
