An estimated 6% of human greenhouse gas emissions are the result of enteric methane production by cows. Asparagopsis taxiformis, a semi-tropical alga, is one solution. Supplementation of this alga to cows at a small percentage of their daily intake has reduced methane emissions by over 98% in trials. This success has led to multiple commercialization attempts globally, although no Asparagopsis tax
Studien undersöker effekter av social distansering och distansundervisning under COVID-19-pandemin bland universitetsstudenter och gymnasieelever i Sverige och Norge. Studier som genomförts under det senaste året visar att studenter har påverkats negativt av pandemin men det finns ingen jämförande forskning mellan de två till synes liknande länderna. Syftet med studien var att undersöka om det fanThe study investigates the effects of social distancing and online education during the COVID-19 pandemic on university students and high school students in Sweden and Norway. Through studies conducted in the last year it appears that students have been negatively affected by the pandemic but there is no comparative research between the two nations. The purpose of the study was to discern if there
What indicates that the Scandinavian bog bodies were places in bogs as a result of a ritual act? This paper will try to look into this by studying different cases of bog bodies from the Early Iron Age. To answer this question, I will examine the various theories researchers provide regarding bog bodies and why they were deposited. In a time period and region which is mainly dominated by cremation,
This research aims to improve the understanding of the relationships between formal and informal strategic planning in reference to performance among SMEs. A qualitative case study was chosen as the approach for this thesis. The data was collected by conducting ten interviews with ten different manufacturing SMEs in Baden-Württemberg, Germany. A purposive sampling was conducted to ensure relevance
This thesis examines representations of homosexual men in Swedish media and public information campaigns during the hiv/aids epidemic, using materials published 1983-1996. The thesis centers on how concepts such as homonormativity and homonationalism are reflected in the discourse, along with an exploration of the rhetorical strategies employed by journalists to increase readership. A thematic ana
The digitalisation and introduction of social media is a factor that today affects children’s lives a lot. So called “kidfluencers” are a phenomenon that is booming and that is becoming more and more frequent. The aim of this essay is to look into the impact that social media and “kidfluencers” may have on children in Sweden today. An interview study has been done, in which parents and educators
Background: Knowledge is increasing about TSC-Associated Neuropsychiatric Disorders (TAND), but little is known about the potentially confounding effects of intellectual ability (IA) on the rates of TAND across age, sex, and genotype. We evaluated TAND in (a) children vs. adults, (b) males vs. females, and (c) TSC1 vs. TSC2 mutations, after stratification for levels of IA, in a large, internationa
Uppsatsen tar upp museipedagogik på Statens Museum for Kunst i Köpenhamn. Eftersom det är ett konstmuseum handlar pedagogiken om konstpedagogik men också om pedagogik som står i relation till skolan. De pedagoger som tas upp är de som varit speciellt inflytelserika för 1900-talets skola och undervisning. Pedagoger som Piaget, Vygotskij, Dewey och Klafki nämns såsom förebilder även till museipedago
Background: To assess the quality of life of people with dementia, measures are required for self-rating by the person with dementia, and for proxy rating by others. The Quality of Life in Alzheimer's Disease scale (QoL-AD) is available in two versions, QoL-AD-SR (self-rating) and QoL-AD-PR (proxy rating). The aim of our study was to analyse the inter-rater agreement between self- and proxy rating
Objectives: To investigate the prevalence of obesity among different types of employment status in the Italian working population, and to examine associated risk factors. Material and Methods: Cross-sectional survey of 36 814 people that declared to have been occupied with the same type of contract for at least 5 years was analyzed. Multivariable logistic regression models were built considering w
I denna studie har elva svenska idrottare som dopat sig intervjuats – tio styrkelyftare och en tyngdlyftare. Idrottarna har varit verksamma på tävlings- till elitnivå, och har fällts för minst en dopingförseelse 1990 till och med 2006. Syftet med studien har varit att identifiera och analysera sociala processer som ligger bakom bruket. Anabola Androgena Steroider (AAS) var det preparat som samtlig
Phthalates are ubiquitous in indoor environments, which raises concern about their endocrine disrupting properties. However, studies of human uptake from airborne exposure are limited. We studied the inhalation uptake and dermal uptake by air-to-skin transfer with clean clothing as a barrier of two deuterium-labelled airborne phthalates: particle-phase D4-DEHP (di-(2-ethylhexyl)phthalate) and gas-
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
This paper presents a comparison of horizontal equity in health care utilization in 10 European countries and the US. It does not only extend previous work by using more recent data from a larger set of countries, but also uses new methods and presents disaggregated results by various types of care. In all countries, the lower-income groups are more intensive users of the health care system. But a
The length of the menstrual cycle was compared in women with breast cancer, women with benign breast disease, and controls. Older women in general tended to report shorter menstrual cycles (P < 0.05). After correction for the age difference, breast cancer patients still reported a shorter average menstrual cycle length than benign breast disease patients and controls (P < 0.006). Very short cycles
The electrochemical and electrical properties of geometrically defined electrolyte-filled microelectrodes were studied at various transelectrode current passages, using radiotracer (38Cl and 42K) and electrical techniques. Geometrically, the electrodes were defined by their tip properties that, for standard (single-barrelled, 3.0 M KCl-filled, approximately 10 M[ohm]) electrodes implied a tip open
Groundwater contamination by nitrate is a common problem in many parts of the world. The agriculturally important Shimabara district in Nagasaki, Japan, is experiencing this problem. The general source of drinking water of the study area is groundwater and consequently the nitrate contamination is a significant problem. For this reason, a groundwater investigation was performed and water samples w
Kraven gällande maximalt tillåtna gångavstånd till en utrymningsväg saknar förmodligen en direkt vetenskaplig grund. De är dock resultatet av många års byggande där historien visat vad som fungerat. Exakt vad som givit upphov till gångavstånden är fortsatt okänt och det skulle således kunnat vara en praktisk fråga gällande vad som var möjligt att bygga, lika väl som hur stora avstånd städpersonal The allowed travel distance has probably not been determined scientifically. Yet it indirectly takes a number of factors into account and should therefore not only be seen as a distance that takes a certain time to walk, but also as a certain level of safety. Longer travel distances do extend the walking time but it also makes it possible for a series of factors to increase the risk. The factors t
