Abstract With high poverty and inequality rate, the Government in Brazil have adopted several social assistance programs and strategies in the fight against the ever growing rate of poverty and inequality within it’s population since the 1990s. In recent years, the Bolsa Familia Program have been a major social assistance program in Brazil, and the program have affected more than 13 million poor h

Objectives: Timely discovery and adequate patient management are crucial in non-small cell lung cancer (NSCLC) since long-term survival is only achievable in early-stage disease. In our study, we aimed to elucidate the effects of time to surgery on survival and to assess the impact of the COVID-19 pandemic on elapsed time until surgery. Methods: In total, 2536 Caucasian NSCLC patients who underwen

Popular Abstract in English Animal flight has always intrigued people, and different aspects of animal flight have therefore widely been studied by biologists, physicists and engineers. At least to me, the aspect concerning the aerodynamics of animal flight in particular is very interesting because of the complex temporal varying wake dynamics as a result of continually wing morphing in flapping fThe efficiency and performance of a flying animal is directly related to the aerodynamics around its body and flapping wings. Here, I have developed methods for quantifying the wake dynamics around a flying animal. The results are used to estimate the aerodynamic performance of flapping flight. Using these methods, I have studied flight of the Pied Flycatcher (Ficedula hypoleuca), the Pallas’ Long

Popular Abstract in Swedish Polyklorerade bifenyler (PCB) är ett samlingsnamn för ett antal kemiska föreningar. De utmärker sig genom att de har en god elektrisk isoleringsförmåga och tålighet för höga temperaturer, och de har därför använts i bl.a. transformatorer och kondensatorer men även som mjukgörare i plaster och färger. Sedan det visat sig att exponering för PCB innebar allvarliga hälsoeff

In the water sector, there have been numerous failures in projects aiming at sustainable development and there have been some, but less numerous, examples of successes. However, the most striking observation is the near universal failure to learn from these examples. Somehow, scientists and decision makers have allowed the indications of new approaches and opportunities go undetected because they

Widespread presence of toxic and persistent pollutants in the environment, even at low concentrations, causes risks of adverse effects to human health and the ecosystem. Biological methods for treatment of water streams and removal of persistent pollutants are of great interest due to their simplicity, low cost, and mild operational conditions without harmful by-products. The purpose of this resea

International researchersWhen a department plans to host a guest researcher, many questions crop up. Where is the guest going to live? What is the position about visas? Schools for children, language training and employment questions are other examples.Below you will find useful tips and checklists that simplify matters for both the department and the person concerned.Points to bear in mind, infor

A part of this thesis has been devoted to present general recuperator technology such as available gas turbine recuperator types, applications where recuperators are utilized, recuperator materials etc. An investigation of some compact and highly efficient heat transfer surfaces, for intended use in gas turbine recuperators, include the following surfaces: · Cross Wavy (CW) primary surface. · Cor

Cartridge cases are often the sole items left behind after a shooting incident and DNA traces from these can identify persons connected to the shooting. However, the chance of retrieving usable DNA profiles from cartridge cases is limited, due to the low amounts of deposited DNA and subsequent DNA loss associated with the firing process. In the current study, we set out to increase the DNA recover

Event-based control is a promising concept for the design of resource-efficient feedback systems, where events such as sampling, actuation, and data transmissions are triggered reactively based on monitored control performance rather than a periodic timer. In this thesis, we investigate how sampling and communication events should be triggered to fully exploit the potential of event-based control

Buildings are responsible for a third of global greenhouse gas emissions, with much of their life cycle impacts stemming from embodied impacts of building materials. Both at EU and Member State level, circular economy and resource efficiency policies are promoting production of lower-impact building materials with secondary material input. However, secondary material strategies do not result in ca

Motivation: The Tundra Trait Team (TTT) database includes field-based measurements of key traits related to plant form and function at multiple sites across the tundra biome. This dataset can be used to address theoretical questions about plant strategy and trade-offs, trait–environment relationships and environmental filtering, and trait variation across spatial scales, to validate satellite data

Background and aims Curative surgery saves ≈50% of all patients with colorectal cancer (CRC) while remaining patients have synchronous or will develop metachronous metastases. Presently, the single most important prognostic factor is histopathological detection of disseminated tumor cells in regional lymph nodes. However, the routine method has several limitations. The aim was to identify biomarke

Diffusion MRI (dMRI) can probe the tissue microstructure but suffers from low signal-to-noise ratio (SNR) whenever high resolution is combined with high diffusion encoding strengths. Low SNR leads to poor precision as well as poor accuracy of the diffusion-weighted signal; the latter is caused by the rectified noise floor and can be observed as a positive bias in magnitude signal. Super-resolution

Introduction: Clinical trials have shown promising results for extended half-life factor VIII concentrates but little is known about individuals' valuation of haemophilia treatment attributes. Aim: To assess patient/caregiver and population valuation of treatment attributes of prophylactic regimens for people with severe haemophilia A. Methods: Members ≥16 years of the Swedish Haemophilia Society

Background: Trauma to the pancreas is rare but associated with significant morbidity. Currently available management guidelines are based on low-quality evidence and data on long-term outcomes is lacking. This study aimed to evaluate clinical characteristics and patient-reported long-term outcomes for pancreatic injury. Methods: A retrospective cohort study evaluating treatment for pancreatic inju
