Det är väl känt att kolmonoxid (CO) är en giftig och hälsofarlig gas som är luktlös, färglös och smaklös vilket gör den svår att detektera utan analytisk utrustning. Men under senaste åren så har forskning bevisat att i små doser så kan kolmonoxid användas som en terapeutisk substans för att lindra malaria, cancer, lung-, hjärt- och kärlsjukdomar men även reducera mängden inflammatoriska substanseIt is well known that Carbon monoxide is a toxic and hazardous gas, but during recent years it has been proven that using a controlled concentration, carbon monoxide can in fact be used as a therapeutic agent, and can contribute to decrease malaria, treat cardiovascular and lung diseases and potentially even treat cancer, among other things. The main problem in using carbon monoxide directly is th

Recently, the urbanization in China caused much social problem in China, and one of the distinctive features of urbanization is the increasing population density. This thesis aims to discover the relationship between population density and fertility in China by choosing Xinjiang region as an example, other determinants of fertility in Xinjiang region were also examined, such as average income, emp

Have you ever wondered how we can reduce food waste and at the same time provide a more sustainable and eco-friendly environment to all of us? One of the United Nations goals is to bring by 2030 more responsible consumption and production to the environment. Industries are paying annually for solid waste disposal up to 16,000€ and at the same time, the most preferred way to dispose it is through l

A strategic and diverse set of passivation methods for gallium arsenide nanowires wasstudied. Using a time-resolved photoluminescence setup at100 Kand300 K, the radiativerecombination of charge carriers was resolved on a picosecond time scale. Characterizationof these nanowire arrays on their native substrates provided reliable and nondisruptivemeasurements of thousands of nanowires simultaneously

In the last decade, there has been a substantial shift from actively managed funds to funds with passive investment strategies. This shift was also observed by Shleifer (1986), who identified that passive investment funds began to significantly increase their ownership of the S&P 500 in the period between 1975 and 1983. As the ownership of the stock market increased as the number of index fund

Reindeer (Rangifer tarandus) are the most common large herbivores in the arctic. With a habitat spreading over the entire circumpolar region, they can have a substantial effect on plant species composition and ecosystem processes and functions. They affect plant species composition by trampling, removal of foliage and by fertilization through dung and urine. These alterations in species compositio

Therefore, the purpose has two aspects, one descriptive and one explanatory. Conceptual framework: The framework is based on a preliminary investigation, including three in

Traditionellt sett har höga byggnader uppförts med stomme av antingen betong eller stål. Trä som byggnadsmaterial har däremot använts till största del i mindre hus. I takt med att byggnadstekniker har utvecklats och byggnadssektorn letar efter mer miljövänliga alternativ börjar även höga träkonstruktioner bli mer eftertraktat. Ett problem med dessa konstruktioner är att trä är ett vekare och lättaTraditionally, high buildings have been built with either concrete or steel. Wood as a building material, however, has mostly been used in smaller buildings. As building techniques have been developed and the construction sector are looking for more eco-friendly alternatives high wooden structures are more sought-after. One problem with these designs is that wood is a weaker and lighter materials

Bakterier som lever i vatten brukar ta sig fram med hjälp av långa trådliknande utskott,så kallade flageller. Denna simteknik är väldigt annourlunda jämfört med det vi oftast ser i vår omvärld, att simma med fenor eller åror är nämligen inte särskilt effektivt för bakterier. Detta har att göra med vattnets radikalt annourlunda hydrodynamiska egenskaper på mikroskalan. Man brukar tala om det så kalMicroswimmer is a term that denotes small selfpropelling agents, such as bacteria, algea or artificial robots. Depending on the flow field they set up they can be categorized into two classes: pushers (e.g. E. coli ) and pullers (e.g C. reinhardtii ). The occurrence of jets, eddies and flocking have been observed in systems of dens pusher suspension. This phenomenon is called active turbulence. Th

Visste ni att teknologi som används för avgasrening kan användas i framtidens elbilar? I den katalytiska avgasrenaren i bensin- och dieselbilar finns partiklar som driver kemiska reaktioner i avgasflödet som omvandlar föroreningar till ofarliga ämnen utan att själva förbrukas. Det är samma partiklar som också används i bränsleceller, en lovande teknologi för framtidens fordonsdrift. Trots att dessStudying catalysts under such non-equilibrium conditions is a step towards approaching more realistic reaction conditions for working catalysts. Reactivity during phase changes of ultra-thin FeO2 films grown on Pt(111) are studied in situ with Ambient Pressure X-ray Photo Emission Spectroscopy and Quadrupole Mass Spectrometry, while running the CO oxidation reaction at 160°C and 0:6 mbar. These ph

Vatten är en nödvändighet för ett funktionellt samhälle. Grundvatten är, förutom yt- och havsvatten, en av de stora resurser som vi använder för att tillgodose vårt vattenbehov. Globalt varierar världens vattenanvändning och tillgängligheten av dricksvatten, där en stor andel har någon form av problem med att upprätthålla en god vattenstatus med avseende på vattenkvalitet och kvantitet. Även i SveWater is a necessary resource for a sustainable society. Groundwater is one of our supplies for potable water, other than surface- and seawater. Around the world the usage and accessibility of potable water varies, and many in places there are problems with maintaining a good water situation regarding both water quality and quantity. Even in Sweden, the water situation is not ideal. Even though we

Love, witches and magic has attracted the attention of humans since the dawn of time – clearly, during some periods more than others. This essay concentrates on one period of time when such an interest peaked, namely the Augustan era, when a wave of witch representations emerged in Roman literature. By discussing texts written by the famous poets Horace, Vergil and Ovid, alongside the less well-kn

Young adult novels about suicide are questioned pieces of literature. Fears of suicide contagion and the perceived unsuitability of such narratives for adolescents lie at the centre of this conflict, which has resulted in the banning of books and other censorship moves. Suicide in literature has been the focus of relatively scarce previous research, and there is a need for further literary critici

The report follows a case study approach to come up with a joint replenishment strategy in order to reduce logistics costs and also meet the customer’s demand, by analysing the current logistics cost for the upstream of supply chain where the spare parts are shipped f

For a coating to withstand scratches, and have good abrasion resistance are extra important for some applications. PVC floors for example are often exposed to extensive wear, and it is therefore important to coat it with a coating that can withstand the hard use. One type of UV coating that have good scratch and abrasion resistance is a coating containing urethane acrylate resin. This type of re
