Påvisande av Helicobacter spp hos hund : en metodologisk studie
The purpose of this study was to develop a reliable molecular-genetic method to determine the different species of helicobacter in dogs. The study is part of a larger project to map the prevalence of Helicobacter spp in healthy and sick dogs in Sweden, and to determine the possible connection of Helicobacter spp infection with gastrointestinal diseases in dogs.
Several published studies have reported on the prevalence of Helicobacter spp in dogs. The problem is that three of the most common species are so alike that a 16SrRNA-PCR with sequencing is not able to differentiate between them. In this study, DNA has been purified from samples and then a Multiplex PCR has been performed. Multiplex PCRs use multiple primers in one single PCR.
Utlokaslisering till Indien : En fallstudie av Multiplex utlokalisering av ekonomitjänster
På grund av en hårdnande konkurrens på världsmarknaden har företags investeringar utomlands ökat frekvent de senaste åren. Fler och fler företag flyttar sina ekonomitjänster till lågkostnadsländer för att uppnå kostnadsfördelar. Indien utgör idag motiv för denna utlokalisering av ekonomitjänster främst på grund av deras höga utbildningsnivå, goda engelskkunskaper samt låga löner. Genom en egen modell som bygger på dessa teorier presenteras fyra bakomliggande faktorer; krav, kultur, kunskap och kostnader vilka utgör hinder och vidare möjligheter för utlokalisering av ekonomitjänster. Vidare visas vilken typ av ekonomitjänster som lämpar sig bäst för utlokalisering till Indien. Via en fallstudie av det multinationella företaget Multiplex utlokalisering av ekonomitjänster till Indien nås djupare insikt i problemet.

Underh?llande propaganda? Hur popul?rkultur framst?ller USA:s makt i en tid av dess f?r?ndring
Popular Culture is inherently political and the connection between popular culture and world politics in particular is something that has been established through years of research by multiple scholars. In this essay, my aim is to analyze how American Power is represented in popular culture. This is done in context of the decline of the American led liberal hegemony and a new Multiplex world order. A world order with multiple influential actors with varying levels of power. To analyze the way popular culture portrays American power, I have used the movie Top Gun: Maverick (2022) as an example and analyzed scenes from the movie.
FPGA-design av en STDM-baserad multiplexer för seriell multiprotokollskommunikation
The remotely operated underwater vehicles that the client develops have needs of different kinds of data channels. In order to minimize the need of physical cable between the control unit and a ROV, a multiplex protocol has been developed. The protocol has been designed with the aim of using the bandwidth of the transferring link as efficient as possible.The different kinds of data channels used during this thesis project is; RS232, RS485 and CAN. ROM and FIFO-memories have been used to be able to effectively manage the different data channels. All the reading and sending of these channels have been implemented in FPGA-technology, the coding is made generic so that it will be easier to add more channels to the system in the future.The multiplex protocol is a modified version of the method STDM and it is a proprietary protocol.

Både T. vaginalis och M. genitalium har associerats med infektion av humant papillomvirus (HPV) samt kan bland annat orsaka salpingit med infertilitet som potentiell komplikation. Patogenerna har även beskrivits öka risken för transmission av HIV. Syftet med studien var att detektera T.
Utveckling av en PCR metod för identifiering av nyupptäckta mjölksyrabakterier
Flera olika arter av mjölksyrabakterier som ingår i släktena Lactobacillus och Bifidobacterium har hittats hos bin och i deras honung. Idag finns ingen effektiv metod för identifiering av bakterierna. Syftet med detta projekt är att utveckla en metod för snabb identifiering genom att hitta lämpliga primers till olika mjölksyrabakterier och därmed få fram en Polymeraskedjereaktion (PCR) metod. Ribosomal ribonukleinsyra (rRNA) generna eller 16S-23S rRNA intergenic spacer region (ISR) används ofta vid design av primers, som därefter används i PCR för att identifiera olika bakterier. Deoxiribonukleinsyra (DNA) visualiseras i agarosgelen med hjälp av SYBRgreen I som fluorescens på ultraviolett (UV)-ljusbord.
Evaluation of an automated multiplex real-time RT-PCR assay for rapid detection of Influenza A and B viruses
Influenza is a viral infection that affects global health and economy with its endemic and sometimes pandemic spread. Rapid detection of Influenza viruses enables antiviral use and can bring financial savings. It is also essential for the global surveillance of prevalent Influenza strains. RT-PCR is considered the most specific and sensitive method for detection of Influenza, but Influenza mutates at a high rate and it is therefore crucial that RT-PCR methods are updated regularly.In 2014, Cepheid released their Xpert Flu/RSV XC assay, which can detect Influenza A and B and RSV by multiplex RT-PCR in approximately one hour. The aim of this study was to evaluate this assay at Laboratoriemedicin Västernorrland by using the laboratory?s previous PCR assay for detection of Influenza viruses as reference method.Real-time RT-PCR was used to compare Xpert Flu/RSV XC to the reference method.
Optimization of immunoassay parameters in multiplex in the high throughput protein detection technique Proximity Extension Assay
The ability to detect protein-based biomarkers, which are linked to different diseases like colorectal cancer, is very important as a diagnostic tool. Usually complex biological samples like blood are studied which will contribute to different technical issues when performing an assay. The aim with the project is to optimize and develop the high throughput protein detection technique Proximity Extension Assay, PEA, into a 96-plex panel, in hopes of discovering an expression profile for colorectal cancer. PEA was developed by Olink Bioscience and allows specific proteins in a sample to be quantitatively transformed into nucleic acid sequences that are subsequently detected and quantified with real-time PCR. Two proximity probes containing oligonucleotide sequences bind pairwise to target protein and when brought in proximity, a DNA polymerase will extend a hybridization arm from one probe over to the second forming a double-stranded DNA sequence that can serve as a template in real-time PCR.
