Objectives. To study the in vitro stability of free and complexed forms of prostate specific antigen (PSA) in blood samples in order to establish guidelines for specimen handling, in particular for the clinical utility of the analysis of percentage free PSA. Methods. Blood samples were collected and processed to generate serum, heparin plasma, and EDTA plasma. Three different two-site immunoassays

This thesis considers the problem of improving the performance of observed time difference of arrival (OTDOA) based positioning for Narrowband Internet of Things (NB-IoT). A new iterative low-complexity algorithm based on expectation maximization successive interference cancellation (EM-SIC) is presented. The algorithm tackles the near-far problem by using an iterative SIC, where for each receivedThis thesis considers the problem of improving the performance of observed time difference of arrival (OTDOA) based positioning for Narrowband Internet of Things (NB-IoT).

The EU has pushed for more Green Public Procurements (GPP) by its member states. Accordingly, Sweden has adopted a GPP policy of 60 % organic consumption in the public sector. The aim of this study is to investigate the barriers which Swedish municipalities are facing to increasing their purchase of organic food. Through a self-completed survey, municipality workers' perceptions of barriers wi

Greening projects are becoming increasingly popular as part of urban transitions towards sustainable cities. Many academic studies have shown that under certain conditions these projects do not address or even execrate existing socio-spatial inequalities. This research attempts to explore the narrative on UGI and environmental justice in academic literature and in the practitioner narrative at mun

With the rapid development of digitalization and technology, the consumption environment has also changed a lot. Online food delivery has become a very popular way of ordering, especially with the covid-19 outbreak. But at the same time, the dark side it brings to sustainability cannot be ignored. This study aims to describe and understand the attitude and perceptions that influence consumer behav

Det här projektet har handlat om utmaningar. Utmaningen att transformera en fabrik, att orientera sig i historien, att hitta balansen och att gestalta hållbart för framtiden. Men framförallt om att utmana besökaren.

Idag präglas världen av teknikutvecklingen som både anses vara en fördel och en nackdel. För den kriminella världen och organiserade ekonomiska brottsligheten är digitaliseringen en fördel. Moderna tekniska lösningar gör det enklare för gärningsmännen att begå brott, såsom penningtvätt vilket regleras i penningtvättslagen (2017:630). Penningtvättsbrott förekommer både nationellt som internationellToday, the world is characterized by technological development that could be considered both as an advantage and a disadvantage. For the criminal world and organized economic crime, digitalization is seen as an advantage. The modern technical solutions make it easier for the perpetrators to commit crimes, such as money laundering which is regulated in the Money Laundering Act (2017:630). Money lau

In the last couple of years, a conflict between football supporters and police have occurred. This conflict has resulted in many instances of violence between the two parts and protests from the supporters. Some that have been met with even harder legislation around and during football games in Stockholm. The police are actively trying to make a safer envoierment during the games while the support

ABSTRACT: Secretory leucocyte protease inhibitor, SLPI, is a low‐molecular‐weight, acid‐stable protein present in the liquid part of fresh human ejaculate but not demonstrable in the gel structure. No fragmentation of SLPI occurred during gel dissolution, but a slow proteolytic cleavage of SLPI was seen on incubation of the liquified semen at 37°C. The same pattern of degradation products was seen

Objectives.: To assess the comparability of the Tandem-R and IMx serumprostate-specific antigen (PSA) assays across levels of the ratio of free-to-total serum PSA found in a community-based population of healthy men. Methods.: Banked serum samples from the baseline component of the Olmsted CountyStudy of Urinary Symptoms and Health Status Among Men were thawed and analyzed using the Tandem-R and I

Adequate bowel cleansing is essential for high-quality colonoscopy. Recently, a new very low-volume 1 litre (1L) polyethylene glycol (PEG) plus ascorbate solution (ASC) has been introduced. Our aims were to assess the effectiveness and tolerability of this product compared to low-volume 2L PEG-ASC and high-volume 4L PEG solutions, in a real-life setting. In six endoscopy units in Sweden, outpatien

"Jag har arbetat med barn i utsatta situationer i 30 år och har aldrig tidigare sett en svårare situation." Så beskrev en representant från civilsamhället situationen för barn och familjer som nyligen sökt asyl i Sverige, på en konferens i december 2019, som samlade ett stort antal frivilligorganisationer och offentliga aktörer. Organisationerna som fanns representerade på konferensen hade sökt oc

OBJECTIVE: To investigate the value of ultrasonographic data in predicting total knee replacement (TKR).DESIGN: Data from the Musculoskeletal Pain in Ullensaker study (MUST) was linked to the Norwegian Arthroplasty Register to form a 5-7 year prospective cohort study of 630 persons (69% women, mean (SD) age 64 (8.7) years). We examined the predictive power of ultrasound (US) features, i.e. osteoph

This thesis analyses police officers' work with internal control of foreigners through a discussion of, among other things, the nation-state, rule of law ideals as well as the police profession and the conditions surrounding that profession. Internal control of foreigners, practised by police officers has two main aims: to control migration and to fight crime amongst people unauthorised to reside

Ectopic expression of transcription factor combinations has been recently demonstrated to reprogram differentiated somatic cells towards the dendritic cell (DC) lineage without reversion to a multipotent state. DCs have the ability to induce potent and long-lasting adaptive immune responses. In particular, conventional type 1 DCs (cDC1s) excel on antigen cross-presentation, a critical step for ind

α1-Antitrypsin is a glycoprotein that separates into five electrophoretic fractions, viz. M2, M4, M6, M7 and M8. Con A-Sepharose separates the protein into three fractions according to the branching degree of the three oligosaccharide chains. The Con A affinity is identical for M4 and M7 and for M6 and M8. Within each pair the proteins were isolated by rapid chromatofocusing. The M7 and M8 have th

Background: Mutations in BRCA2 cause a higher risk of early-onset aggressive prostate cancer (PrCa). The IMPACT study is evaluating targeted PrCa screening using prostate-specific-antigen (PSA) in men with germline BRCA1/2 mutations. Objective: To report the utility of PSA screening, PrCa incidence, positive predictive value of PSA, biopsy, and tumour characteristics after 3 yr of screening, by BR

This thesis has presented a comparison between two occupied territories Tibet and Palestine as countries that have a long legacy of postcolonialism and strife for self-determination. The comparison was conducted from a postcolonial perspective of how Palestine is being occupied by Israel with full Western backing, while Tibet was occupied by another postcolonial country China. This clearly shows h

Now AI is being used nearly in everything we have. Ranging from hand-wrest watches to household systems used inside houses. According to a report by McKinsey and Co, Artificial Intelligence (AI) is expected to have a significant impact on the economy in the coming years, with the potential to add trillions of dollars annually to the global economy. Furthermore, advances in algorithms and data coll
