Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

Severe acute respiratory syndrome (SARS) är den epidemi som 2003 spred sig från Guangdong provinsen i Kina till 26 länder runt om i världen. Sjukdomen som orksakades av SARS-coronavirus (SARS-CoV), drabbade under utbrottet 8098 personer och tog 774 liv. SARS är ett utmärkt exempel på hur en dödlig sjukdom kan komma från ?ingenstans? för att snabbt, spridas med hjälp av vårt globaliserade samhälle. Viruset utsöndras med luftvägssekret, feces och urin och kan under fuktiga och gynnsamma omständigheter vara infektionsdugligt i upp till fyra dygn. I regel krävs direktkontakt eller nära kontakt mellan smittbärare och frisk individ för att sprida viruset vidare.

Coop Sverige inga?r i ett nordiskt inko?pssamarbete fo?r sina egna ma?rkesvaruprodukter (EMV), Coop Trading. Na?sta a?r, 2012, bryter man sig ur detta samarbete och av den anledningen vill Coop Sverige se o?ver varukraven fo?r sina EMV-produkter. Coop har som ma?lsa?ttning att vara det ledande och mest innovativa detaljhandelsfo?retaget och branschens fra?msta spra?kro?r och inspirationska?lla fo?r ha?llbar konsumtion.

In my thesis I have sand blasted different type of woods - ring-porous and diffuseporous deciduous tree species and conifers - to show different results depending on the species, the direction of the grain and the effects of surface treatment of a blasted surface.The results of my tests were sometimes unexpected, such as that the sand from blasting almost completely disappeared, that all wood surfaces after blasting exhibited a much lighter or paler surface than before and that the diffuse-porous tree species showed differences in hardness between the beginning and end of annual rings.By creating a library of different kinds of wood and sandblasted surface treatment, I have created a reference bank that I will be able to use me in the manufacturing of interiors, furniture and other objects..

Salome is the myth of the Oriental princess who dances for her stepfather, Herod the tetrark at his banquet. He becomes so enchanted by Salome's dance that he allows her to wish for what she wants. On the advice of Queen Herodias, Salome's mother, she asks the head of prophet John on a platter. Herod is horrified, but grants Salome's desire.This is the first in a series of Salome petitions as Mark and Matthew in the New Testament. Salome has since then never ceased to fascinate artists and writers through the ages.

Rabiesvirus är en allvarlig sjukdom globalt då minst 35 000 människor mister livet varje år på grund av den fatala sjukdomen. Idag finns inget botemedel mot rabiesvirus när sjukdomen brutit ut, det enda skyddet är vaccinering. Hur immunförsvaret reagerar på viruset, varför inte immunförsvaret klarar av att eliminera viruset och vad post-vaccinering innebär undersöks i det här arbetet. Rabiesvirus utsöndras i saliv och den vanligaste infektionsvägen för rabiesvirus är via bett från infekterad individ och för människa är hundbett största risken. När infektion har skett transporteras virus till centrala nervsystemet (CNS) via intraaxonal transport. Rabiesvirus är ett neurotropt virus och replikerar i CNS.

This thesis studies three kinds of debate formats. Those are DN Debatt, SVT Debatt and Ring P1. The focus lies in the interrelations between these forums and how they interact with theri audience. Since debate is an essential tool for political and democratic practice, it is vital to study the movements and the realtions between these media formats. Some of the questions in this study are: What happens with a debate topic when it moves between the formats? In which way are the formats democratic and what does their communicative forms mean for political practice and citizen participation? The study shoes how the interpretation of a specific term can expand during a debate.

Genom att likna den rasistiska strukturen i Sverige med ett smittsamt virus belyser Jenny Karlsson ett aktuellt problem ur en alternativ synvinkel. Detta arbete handlar om att lära sig att se och förstå hur en rasistisk struktur fungerar, för att kunna bromsa rasismens spridning. För att göra detta har ämnet rasism komprimerats och förpackats i en läkemedelsförpackning. Denna förpackning beskriver vardagsrasismen som tidiga symptom och följderna av strukturell diskriminering som konsekvenser av obehandlad rasism. Genom rollen som designer kommunicerar Jenny problematiken med att näst intill ingen identifierar sig som rasist, när de flesta av oss ändå är det..

In this thesis we calculate the Hawking mass numerically for surfaces in Kerr spacetime. The Hawking mass is a useful tool for proving the Penrose inequality and the result does not contradict the inequality. It also does not contradict the assumption that the Hawking mass should be monotonic for surfaces in Kerr spacetime. The Hawking mass is quasi-local and defined by the spin coefficents of Newman and Penrose, so first we give a discussion about quasi-local quantities and then a short description of the Newman-Penrose formalism..

Larvae of Lepidopteran Manduca sexta and Spodoptera littoralis are pests of economical importance in several horticultural and agricultural crops. Knowledge of insect feeding preferences and behavior is crucial in order to find economically and ecologically sustainable solutions to the problems caused by these herbivores. The aim of this thesis was to study the behavior and the induced feeding preferences in larvae of M. sexta and S. littoralis when reared on certain host plants. The hypothesis was that larvae of M. sexta would have an innate preference for plants of the Solanaceae family and therefore discriminate the previously experienced nonhost when faced with the choice between a true host and the previous food source.

The cat has become a popular pet. To secure a prosperous cat-human relationship, the cat owner has to understand what kind of animal the cat is and what requirements need to be fulfilled. The purpose of this literature review is to summarize kittens? needs of socialization, anthelmintics, nutrition, vaccination and gonadectomy, until the age of six months and to give the cat owner information on how to care for the cat during this period. Articles were search for in ScienceDirect, Primo and Scopus.

The demand for animal products has increased in the last decades, especially for poultry and pork. Pork production has increased drastically globally, and also in Uganda. Thirty-one percent of Uganda´s population lives in poverty. Pig production is believed to play a crucial role in poverty alleviation, because of the ability to convert low quality feed into high quality protein together with high reproductive potential. African swine fever (ASF) is a lethal disease of domestic pigs often characterized by haemorrhagic fever and with mortality rates up to 100%. The disease is endemic in most sub-Saharan countries and since 2007 in the Russian Federation and Caucasus area.
