OBJECTIVE: To describe the distribution of HIV-1 variants in population-based national surveys conducted in sub-Saharan African countries between 2015 and 2022.DESIGN: Multicountry analysis.METHODS: Sixteen population-based national surveys, conducted between 2015 and 2022, were analyzed. Survey participants were eligible if HIV genotyping was successful. In most countries, people with HIV (PWH) w
Objective. The aim was to theoretically and experimentally investigate recovery in SPECT images with objects of different shapes. Furthermore, the accuracy of volume estimation by thresholding was studied for those shapes. Approach. Nine spheres, nine oblate spheroids, and nine prolate spheroids phantom inserts were used, of which the six smaller spheres were part of the NEMA IEC body phantom and
Introduction: Most studies determining speakers’ perceived gender as binarily female or male are reliant on F0 perception, although other vocal parameters may also contribute to the perception of gender. The current study focused on the impact of breathiness on the perception of speakers’ gender as a biological variable (feminine or masculine). Methods: n = 31 normal hearing, native English speake
The fate of iron (Fe) in freshwaters is largely influenced by chemical interactions with natural organic matter (NOM). However, the knowledge about the molecular structure of the Fe species formed in association with aquatic NOM is still limited. In this work we have studied the interactions between Fe(III) and aquatic organic matter from the Suwannee River at a range of pH values and Fe concentra
Development of relevant models of Parkinson's disease (PD) is essential for a better understanding of the pathological processes underlying the human disease and for the evaluation of promising targets for therapeutic intervention. To date, most pre-clinical studies have been performed in the well-established rodent and non-human primate models using injection of 6-hydroxydopamine (6-OHDA) or 1-me
Background: Vaccination coverage for infant vaccinations in the Swedish National Immunization Program (NIP) has been high for more than a decade, with approximately 97% of 2-year-old children fully immunized. Vaccination coverage against Human Papilloma Virus (HPV) has been around 80% since introduction for girls in 2012. This indicates high parental confidence in the NIP, but as seen in other Eur
BACKGROUND: Recurrent ischemic stroke (IS) increases the risk of cognitive decline. To lower the risk of recurrent IS, secondary prevention is essential. OBJECTIVE: Our aim was to compare post-discharge secondary IS prevention and its maintenance up to 3 years after first IS in patients with and without Alzheimer's disease and other dementia disorders. METHODS: Prospective open-cohort study 2007-2
Summary form only given. When designing symmetric ciphers, security and performance are of utmost importance. When selecting a symmetric encryption algorithm, the first choice is whether to choose a block cipher or a stream cipher. Most modern block ciphers offer a sufficient security and a reasonably good performance. But a block cipher must usually be used in a "stream cipher" mode of operation,
The theoretical findings of the thesis is composed of three parts, it consists of (i) a framework for social entrepreneurship, (ii) some pitfalls and success factors and (iii) a perspicuous design guide. These findings was a result of field research during a long time – more than 5 years, 2000-2005 – and the scientific purpose was to give a broad description and understanding of the research probl

Intranasal drug delivery is a practical and accessible method for treating localized symptoms as well as achieving systemic drug absorption. The approach takes advantage of the permeability, vascularization, and limited enzymatic activity of nasal tissue, leading to enhanced drug absorption. Moreover, drugs can bypass the blood-brain barrier and directly reach the brain through the olfactory route
Climate issues are currently of attention in various contexts as changing climate factors affect us in many ways. One of these effects is the influence on the probability and frequency of fires, although other factors, especially anthropogenic ones, also play a role. In the Diyarbakir region, a Kurdish-Turkish province affected by the PKK's conflict (Partiya Karkerên Kurdistan - Kurdistan Work
This work consists of seven essays, with each concerning a specific subject that is related to architecture. There is additional text, which pertains to this work's examination requirements for graduating the architecture-program at Lund Technical University. This work is a creative explorations through writing as a tool; through text; becoming able to formulate, conceptualize, develop and ext
In a world of rapid biodiversity loss, raptors are vulnerable due to their longevity and low reproductive rates. The red kite (Milvus milvus) is one of few migratory raptors breeding exclusively in Europe. It has previously experienced steep population declines caused mainly by persecution but mostly recovered, no longer classified as globally endangered. However, negative population trends persis
Abstract The food industry and we consumers face a major challenge, to reduce food waste. We consumers have a food waste of about 95 kilos a year. Of this, approximately 28 percent is considered to be thrown away on incorrect grounds. Bread waste amounts to 80,400 tonnes each year. The loss occurs throughout the value chain. One of the reasons for the high waste of consumers is that the bread
In this paper, we revisit the question of key recovery using side-channel analysis for unrolled, single-cycle block ciphers. In particular, we study the Princev2 cipher. While it has been shown vulnerable in multiple previous studies, those studies were performed on side-channel friendly ASICs or older FPGAs (e.g., Xilinx Virtex II on the SASEBO-G board), and using mostly expensive equipment. We s
Background: Current guidelines for the treatment of severe TBI recommend maintaining a cerebral perfusion pressure (CPP) at 60–70 mmHg. In our institution, as well as others, an alternative algorithm—originally named the Lund concept—has been used. This treatment algorithm employs metoprolol and clonidine to limit CPP, accepting levels below 60 mmHg, with the aim of reducing cerebral edema. Previo
Globally, suicide is a leading cause of mortality among teenage children and adolescents. Alcohol and other substances of abuse may influence both the decision to commit suicide and the choice of method. However, only few studies focused on toxicological findings in child suicides. The aim of this study was to map postmortem toxicological findings in child suicides in Sweden. Data on age, sex, sui
The Australian Bogong moth (Agrotis infusa) is a small noctuid moth that undertakes annual, nocturnal migrations of up to 1000 km to escape the summer heat of its breeding grounds. The moths travel to cool alpine caves, where they enter a dormant state (aestivation) before returning to reproduce and die. During migration, their brains integrate magnetic and visual cues to guide their flight direct
