Objective: To compare survival times of HIV-1 single and HIV-1 and HIV-2 dual-infected individuals. Design: Prospective open cohort study. Methods: We analysed data from 259 HIV-1-seroincident cases (either HIV-1 single or HIV-1 and HIV-2 dual-infected) from a cohort with long follow-up (similar to 20 years) in order to study the influence of type of infection and infection order on mortality. Sex
This thesis investigates a new type of Phase-Locked Loop (PLL) architecture which combines a phase/frequency detector (PFD) and a digital loop filter. The quantization is done by a time-to-digital converter which continuously shrinks the pulse coming from the PFD and registers how far it propagates. Based on how far into the TDC each pulse propagates, the phase error is determined. The design is f
In recent years cars are becoming more and more connected and it has become commonplace to connect one’s phone to the car interface, allowing streaming of music, making calls and sending messages. The primary technology used for connection is Bluetooth, a short-ranged wireless communication technology that has been around since 1999 and improved and expanded upon ever since. It is of vital importa
This thesis presents and analyses the results of the prime working age (25-65), divided into two diverse groups, 25-45 and 45-65, of licensed practical nurses (LPN) perceived occupational status in the Swedish home-care business. The purpose is to understand what influences the perception of two diverse age groups of licensed practical nurses occupational status, bringing nuance to the phenomenon,
The human epidermal growth factor receptor 2 (HER2) is a receptor tyrosine kinase that is involved in many cellular pathways. The HER2 locus is amplified in 12-21% of all breast cancers and is associated with poor prognosis. The introns of HER2 contain two non-coding RNAs: a microRNA (miRNA) named mir-4728 and a box C/D snoRNA-like molecule thus far named snoID_0714. In this study, a list of targe
Problem: The Milky Way disk consists of two distinct components, the thin and thick disk, each with unique kinematical, elemental, and age-related properties. Among all the properties considered, age stands out as the only one that does not exhibit significant overlap, thereby offering clearer separation between the populations. Stellar ages, determined through isochrone fitting, are reliable main
This bachelor has examined how the birkin bag is represented in the television series Sex and the city and Gilmore girls, the reality show The real housewives of Beverly Hills and in a Youtube video from Kylie Jenner. Therefore this essay's purpose is to identify how the birkin bag is represented and which social interactions are therefore being made through all four videos. This essay also ai
New York City's transportation infrastructure plays a critical role in shaping economic growth, housing accessibility, and community development. Challenges like congestion, inequitable transit access, and inefficient zoning regulations hinder sustainable urban growth as the city evolves. Last serving passengers in 1924, the LIRR Bay Ridge Branch remains one of New York City's few freigh
Ultrafast pulse characterization is an ever-growing field of photonics, given the importance of knowing precisely the outcome of ultrafast laser sources and the impossibility to do so with electronics technology. A new approach to the well-established diagnostics technique d-scan has been recently developed in order to expand the capabilities of the d-scan in a single-shot manner. It is known as s
The A4GALT locus encodes a glycosyltransferase that synthesizes the terminal Galα1-4Gal of the P(k)(Gb3/CD77) glycosphingolipid, important in transfusion medicine, obstetrics and pathogen susceptibility. Critical nucleotide changes in A4GALT not only abolish P(k) formation but also another Galα1-4Gal-defined antigen, P1, which belongs to the only blood group system for which the responsible locus
The free volume changes of poly[1-(trimethyl-silyl)-1-propyne] (PTMSP) treated in supercritical CO2 (scCO(2)) were investigated with positron annihilation lifetime spectroscopy (PALS). CO2 is known to plasticize and increase the free volume size of a broad range of polymers. In this work dense PTMSP films were treated with scCO(2) under different pressures and temperatures, resulting in the enlarg
Most pediatric exercise intervention studies, that evaluates the effect on skeletal traits include volunteers and follow bone mass for less than three years. We present a population-based six-year controlled exercise intervention study in children with also bone structure and incident fractures as endpoints. Fractures were registered in 417 girls and 500 boys in the intervention group (3969 person
OBJECTIVES: To evaluate the outcome of treatment for deep sternal wound infection (DSWI) in a nationwide patient cohort, before and after the introduction of negative-pressure wound therapy (NPWT). METHODS: This was a population-based cohort of all patients treated for DSWI in Iceland out of 2446 open heart operations performed between 2000 and 2010. Length of hospital stay, survival and reoperati
A search is performed for dark matter particles produced in association with a resonantly produced pair of (Formula presented)-quarks with (Formula presented) using (Formula presented) of proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the ATLAS detector at the LHC. This signature is expected in extensions of the standard model predicting the production of dark matter par
The study of fluid transport in porous media is crucial for many applications in science and engineering. From a modeling perspective, understanding how diffusion parameters behave when microstructural variations are taken into account is a significant step toward achieving more detailed and accurate model predictions. It is widely recognized that hydraulic tortuosity is typically approximated as
In addition to their natural substrates GDP and GTP, the bacterial translational GTPases initiation factor (IF) 2 and elongation factor G (EF-G) interact with the alarmone molecule guanosine tetraphosphate (ppGpp), which leads to GTPase inhibition. We have used isothermal titration calorimetry to determine the affinities of ppGpp for IF2 and EF-G at a temperature interval of 5-25 °C. We find that
Elementary particles and their interactions are successfully described by the Standard Model of particle physics (SM). However, it has been observed that extensions Beyond the Standard Model (BSM) are required to account for a large part of yet undiscovered particles and interactions, such as Dark Matter (DM).To advance the knowledge of the SM and to pursue DM discoveries, CERN has the ambitious p
Working distributed is increasingly important today with technology being more and more portable while connectivity is still lacking in some areas. Cellphones and laptops are increasingly in use outside the office with connectivity to internal office services being unreliable, either due to lacking speed or inability to have a connection. Different solutions exist. One is a client-server setup wh
This ‘Automatic Test System (ATS) for Network Servers’ Master Thesis project was carried out from September 2000 till March 2001 at Axis Communication AB, Lund. The project was to build a common test system platform for all future tests of Axis network servers’ products. Thus, overcoming the current practice of costly dedicated test system development for individual products. The project is a gra
The aim of this master thesis is to develop a laboratory process that Saab Ericsson Space AB (SE) can use to demonstrate their fault tolerant computer systems at exhibitions. The process is an inverted pendulum shaped as a rocket to symbolize that the company develops fault tolerant control systems for satellites and carrier rockets e.g. for Ariane 5.
The inverted pendulum is a classical
