In Sub-Saharan Africa, being overweight in childhood is rapidly rising while stunting is still remaining at unacceptable levels. A key contributor to this double burden of malnutrition is dietary changes associated with nutrition transition. Although the importance of socio-economic drivers is known, there is limited knowledge about their stratification and relative importance to diet and to diffe
Clinical practice improvements based on quality-register data are influenced by multiple factors. Although there is agreement that information from quality registers is valuable for quality improvement, practical ways of organising register use have been notoriously difficult to realise. The present study sought to investigate the mechanisms that lead various clinicians to use quality registers fo

Sun exposure in combination with skin pigmentation is the main determinant for vitamin D status. Human skin color seems to be adapted and optimized for regional sun ultraviolet (UV) intensity. However, we do not know if fair, UV-sensitive skin is a survival advantage in regions with low UV radiation. New publication in PLOS ONE
Spatial epidemiological analyses primarily depend on spatially-indexed medical records. Some countries have devised ways of capturing patient-specific spatial details using ZIP codes, postcodes or personal numbers, which are geocoded. However, for most resource-constrained African countries, the absence of a means to capture patient resident location as well as inexistence of spatial data infrastr
In this thesis, an instrument using a broadband light beam for remote sensing of insects was developed. The thickness of a free-flying insect wing was measured at a distance of 85 m and with an accuracy of 2 nm. Insects play a key role in the ecosystem and are essential for biodiversity. Detecting and monitoring the millions of insects in our environment is a major challenge. The use of lasers and

Let me clarify that we are not referring to blood plasma, as that pertains to the field of biology. Instead, we are discussing the fourth state of matter, which can be envisioned as a mixture of electrons, atoms, and excited species. To put it simply, it can be described as an ionized gas or a "soup" of charged particles. Our research group focuses on exploring the applications of plasmas in diffe

What if it was possible to identify elements by simply shining a light on them? This proposed method might make it possible to do just that - by analysing just one photograph. Many of us have probably encountered a pen with” invisible” ink that is only visible if you shine on it with a UV lamp. Besides that, these are useful for writing secret messages, they also demonstrate an interesting phenome
A newly developed sample delivery system at MAX IV lets researchers study the properties of aerosol particles. With this knowledge, they can further understand the health and climate effects of soot from burning fuels for transportation or natural emissions. Read more at the homepage of MAX IV
Can metals really burn? Well yes, and you have most definitely seen them burn since metals often are used in fireworks to get different colors. These colorful flames have the potential to be used as alternative to gasoline and other fossil fuels in a clean cycle for storing energy. This cycle will start with a pure metal powder such as aluminium or iron. Then, the powder is burned where energy is

When we cough and speak we launch droplets and if the person launching these droplets is sick from some kind of virus disease, such as COVID19, the droplets can contain viruses. These viruses have been found to be one of the main contributors to the spreading of the pandemic disease. If we can further understand where these droplets end up we can make more effective protective measures during a pa

Throughout life, our lungs are vital organs. For newborns as well as for elderly patients, there is a need for safe and continuous lung monitoring in the healthcare. Some of today's common methods of examining the lungs, such as X-rays and computed tomography are limiting since they can not be applied continuously and carry ionizing radiation. A new technology for clinical lung monitoring is now o

You are out in the woods taking your new profile picture when suddenly a fog rolls in. First you think it is mystical and perfect, but it is so thick that you just look like a blurry blob in the pictures. Do not dispair just yet, this master project might be just what you need. The reason that you are looking blurred in the pictures is scattering. The photons that travel through the fog from you t

Soot is generated from incomplete combustion or pyrolysis of organic compounds. Soot strongly absorbs solar radiation contributing to global warming. Additionally, soot can enter deeply into human organs causing various types of cancers. Understanding soot nano-structures and properties is essential to predict their impacts on climate and human health. Raman spectroscopy (RS) is a powerful techniq
Soot is a light-absorbing material that is formed when hydrocarbons are not completely burned during combustion processes. Soot has significant impacts on climate, glacial regions, agriculture, and human health due to its strong light-absorbing ability, small size and complex structure. Various soot types have different properties, for example biomass soot has lower absorption efficiency than dies

When you are cleaning your car with your high-pressure washer have you ever considered how it works? Well we have and to figure that out we need to see how the liquid looks like in 3D. As is seen in the video above we have 3D reconstructed the surface of a cone-like liquid using a technique developed at the division of combustion physics. This technique apply lasers and a single high-speed camera

Insects are essential to the natural world, playing a vital role in maintaining ecosystem processes and providing valuable ecosystem services. However, studying insect biodiversity has proven challenging and labor-intensive since current methods use manually emptied traps. We recognized the need for a powerful and efficient tool to study insect abundance and richness in forests. So we developed a

Probably you have looked into a candle light and been fascinated by the high intensity of the yellow light! Have you ever been thinking about the origin of this light? This brilliant light actually comes from nano-meter sized carbonaceous particles that we in daily life call soot. Soot particles emitted from a combustion process to the ambient air are black, but at flame temperatures 1500 - 2000 °
