With the ultimate goal to study milk folate bioavailability, a reverse-phase HPLC technique was developed and compared with a radioprotein binding assay. All methods showed similar ranges for folates in cow’s milk, with the variation attributed to seasonal variations and the use of different starter cultures. Most cheese varieties contained slightly higher values for whey cream cheese. Studies usi
Popular Abstract in Swedish Syftet med den här avhandlingen har varit att med hjälp av datorsimuleringar studera laddade polymerers (polyelektrolyters) växelverkan med motsatt laddade sfäriska makrojoner. Redan nu kan en icke kemikunnig person bli helt borttappad, ty: 1. Vad är en polymer? 2. Vad är en sfärisk makrojon? 3. Växelverkan mellan polymer och makrojon? 4. Datorsimuleringar? 5. Vad är dPolyelectrolytes are polymers bearing ionisable groups, which, in polar solvents, can dissociate into charged polymer chains (polyelectrolytes) and small counterions. In aqueous solutions, polyelectrolytes interact strongly with other macroions and in particular they tend to associate with objects of opposite charge and form complexes. Nearly all industrial and biological process involves solution
This case describes an ongoing initiative in Sweden with the aim of measuring the development of the Swedish infrastructure sector. The reason this case was chose is that it is one, of only a very few, national initiatives with a clear aim of taking an holistic approach to assess the development of one large share of the Swedish construction sector. The purpose of this case is to investigate: – Wh
Only 15% to 30% of product development projects require the development of new product concepts. This means that the majority of design projects are carried out within the embodiment design and detail design phases. However, the majority of the research studies on the mechanical engineering design process, or design process for short, have been focusing on the conceptual design phase. The embodime
Although ethnic conflicts are an acute international problem, researchers in international relations have conducted surprisingly little research in this area. The aim with this study is to analyze one aspect of ethnic conflicts, how the elites representing ethnic groups act to make the great powers legitimize their own demands, and delegitimize the demands of the enemy by adducing to norms. In the
Nutrients constrain the soil carbon cycle in tropical forests, but we lack knowledge on how these constraints vary within the soil microbial community. Here, we used in situ fertilization in a montane tropical forest and in two lowland tropical forests on contrasting soil types to test the principal hypothesis that there are different nutrient constraints to different groups of microorganisms duri
Acute myeloid leukemia (AML) remains the most common form of acute leukemia among adults and accounts for a large number of leukemia-related deaths. Mutations in FMS-like tyrosine kinase 3 (FLT3) is one of the most prevalent findings in this heterogeneous disease. The major types of mutations in FLT3 can be categorized as internal tandem duplications (ITD) and point mutations. Recent studies sugge
Serpentinite-hosted ecosystems are potential sites where life may first have evolved on Earth. Serpentinization reactions produce strongly reducing and highly alkaline fluids that are typified by high concentrations of molecular hydrogen (H2) and methane (CH4), which can be used as an energy source by chemosynthetic life. Low-temperature serpentinization at slow-spreading mid-ocean ridges provides
Lateralization is a fundamental property of the human brain that affects perceptual, motor, and cognitive processes. It is now acknowledged that left-right laterality is widespread across vertebrates and even some invertebrates such as fruit flies and bees. Honeybees, which learn to associate an odorant (the conditioned stimulus, CS) with sucrose solution (the unconditioned stimulus, US), recall t
“Commensuration” as an analytic framework for studying the expanding measuring culture in social work Teres Hjärpe, PhD, Lund University, School of Social Work, teres.hjarpe@soch.lu.se. My PhD-project in social work deals with measurements and statistics as knowledge base and source for governance of social work activities. Social workers are currently experiencing the measuring and ranking of the
We measured methane fluxes of a patterned bog situated in Siikaneva in southern Finland from six different plant community types in three growing seasons (2012-2014) using the static chamber method with chamber exposure of 35 min. A mixed-effects model was applied to quantify the effect of the controlling factors on the methane flux.The plant community types differed from each other in their water
BACKGROUND: Cancer of unknown primary (CUP) is a fatal cancer for which incidence trends have changed but detailed survival trends remain unexplored. These could point out successful diagnostic and therapeutic approaches. We investigate survival trends in CUP according to histology, locations of metastases and site-specific causes of death. PATIENTS AND METHODS: A total of 20,523 CUP patients with
Cognitive ability strongly aggregates in families, and prior twin and adoption studies have suggested that this is the result of both genetic and environmental factors. In this study, we used a powerful design-home-reared and adopted-away cosibling controls-to investigate the role of the rearing environment in cognitive ability. We identified, from a complete national Swedish sample of male-male s
Determining climate change feedbacks from tropical rainforests requires an understanding of how carbon gain through photosynthesis and loss through respiration will be altered. One of the key changes that tropical rainforests may experience under future climate change scenarios is reduced soil moisture availability. In this study we examine if and how both leaf photosynthesis and leaf dark respira
Amazonia is an environmentally heterogeneous and biologically megadiverse region, and its biodiversity varies considerably over space. However, existing knowledge on Amazonian biodiversity and its environmental determinants stems almost exclusively from studies of macroscopic above-ground organisms, notably vertebrates and trees. In contrast, diversity patterns of most other organisms remain elusi
Pay-per-use business models where consumers pay for the unit of service (e.g. a wash) without gaining product ownership are often linked to increased environmental performance. Consumers would become more conscious about consumption patterns and companies would take responsibility for product life cycle issues. Such benefits can only be achieved when the business model is intentionally designed to
A three-generation resource family was created by crossing two Berkshire grandsires with nine Yorkshire granddams to identify QTL affecting growth, body composition, and meat quality. A total of 512 F2 offspring were evaluated for 11 traits related to growth and body composition and 28 traits related to meat quality. All animals were initially genotyped for 125 markers across the genome. The objec
As urban areas continue to grow, understanding how species respond and adapt to urban habitats is becoming increasingly important. Knowledge of the mechanisms behind observed phenotypic changes of urban-dwelling animals will enable us to better evaluate the impact of urbanization on current and future generations of wildlife and predict how animals respond to novel environments. Recently, urban ec
Background-Although metabolic risk factors are known to cluster in individuals who are prone to developing diabetes mellitus and cardiovascular disease, the underlying biological mechanisms remain poorly understood. Methods and Results-To identify pathways associated with cardiometabolic risk, we used liquid chromatography/mass spectrometry to determine the plasma concentrations of 45 distinct met
Manly and faithful. A study of the official clerical masculinity ideology in 16th and 17th century Sweden from an age/generation perspective. Historical masculinity studies, a subdivision of gender history, has been one of the most vivid fields of research in the early 21st century. While much empirical research has been done, especially for modern periods, the theoretical concepts are by and lar
