Five students of a rescue training school cycled at 50 W for 20 minutes at 20 °C before walking up to 30 minutes in a climatic chamber at 55 °C and 30 % relative humidity. Four different types of clothing ensembles were used differing in terms of thickness and thermal insulation value were tested on separate days. All subjects completed 28-30 minutes in light clothing, but quitted after 20-27 minu
The management of construction tolerances is a necessary and routine part of the construction activity and is normally brought to our attention only when failures are reported. In a study of tolerance management, the authors found widespread evidence of the same failures and the reasons for them. There seems to be no shortage of experience of the effects of failures in tolerances or of knowledge a
The genetic basis of complete C4 deficiency in a patient with SLE was investigated. Previous studies have demonstrated that this patient has two different major histocompatibility complex (MHC) haplotypes that each contain a major deletion and a non-expressed C4 gene. In the present study, non-expression of the C4 genes was explained by the finding of two distinct C4 gene mutations. A previously d
It is well-known that the morphology of urban areas modifies the variations of climate variables at microscale; known as microclimate conditions. The complexity of urban morphology can lead to undesired wind conditions or excessive air temperature; particularly in extreme weather conditions. This study attempts to quantify the impacts of urban morphology on the evolution of wind speed and air temp
Sverige framhålls ofta som ett föregångsland gällande personlig assistans (PA) och mänskliga rättigheter. Forskning visar dock att bedömningen av rätten till PA styrs av en medicinsk förståelse av funktionshinder och av ekonomiska snarare än funktionshinderpolitiska mål. Nedskärningar har medfört att antalet med statlig assistansersättning har minskat. Syftet med artikeln är att belysa de motstridSweden is often highlighted as a pioneering country in terms of personal assistance (PA) and human rights. However, research shows that the assessment of PA is guided by a medical understanding of disability and by austerity ratherthan by disability policy. Furthermore, the number of people with state-funded PA has decreased. The purpose of the article is to illuminate the contradictions that char
Då människors vardagliga liv allt oftare genomsyras av medierat material är det viktigt att närmare studera hur detta material kan påverka människors verklighetsuppfattning. Denna studie granskar hur hjälporganisationer i sina kampanjfilmer väljer att porträttera lidande och medlidande. De sätt som kampanjfilmerna väljer att illustrera lidande och medlidande på får konsekvenser för hur betraktarna
This study investigates the individual usage of the Dublin Core metadata format in three Swedish Subject Based Information Gateways, SAFARI, Svenska miljönätet and Svesök. The authors also present the reader with an overview of the metadata concept and explains in particular the Dublin Core Element Set. The approach to the study is investigation of Dublin Core application from the viewpoint of thr
The effects of different 4-quinolone antibiotic derivatives (4-Qs) in a number of short-term tests commonly employed for the evaluation of genetic toxicity were studied. Incorporation of [3H]thymidine into mitogen-stimulated peripheral blood lymphocytes was strongly enhanced at a low concentration (1.56 μg/ml) for most of the tested 4-Qs, whereas DNA strand breakage in lymphoblastoid cells was evi
Purpose: The purpose of this study is to investigate the impact of brand logics on the success of brand extensions. Methodology: This study has examined two different case studies to better understand the effect of brand logic. An extensive literature review was done on “brand logics”, specifically Unique Selling Proposition (USP) and the Golden Circle, “brand extensions” as well as “brand identit
In a world where the challenges of climate change, social inequality, economic instability, and geopolitical tensions are ever-present, educators have a unique opportunity—and responsibility—to prepare their students to navigate these complexities. However, educators are also juggling teaching and research, competing deadlines, shifting expectations, institutional paradigms, and limited time and s
Quantitative investigation of insect activity in their natural habitat is a challenging task for entomologist. It is difficult to address questions such as flight direction, predation strength and overall activities using the current techniques such as traps and sweep nets. A multi-spectral kHz remote detection system using sunlight as an illumination source is presented. We explore possibilities
Designkort/tankekort avsedda att användas som stöd för universell utformning i plan- och byggprocesser
Young children with visual impairments tend to engage less with their surroundings, limiting the benefits from activities at school. We investigated novel ways of using sound from a bracelet, such as speech or familiar noises, to tell children about nearby people, places and activities, to encourage them to engage more during play and help them move independently. We present a series of studies, t
An almost k-wise independent sample space is a small subset of m bit sequences in which any k bits are “almost independent”. We show that this idea has close relationships with useful cryptologic notions such as multiple authentication codes (multiple A-codes), almost strongly universal hash families and almost k-resilient functions. We use almost k-wise independent sample spaces to construct new
The proposed Differential Difference Comparator (DDC) provides easy linear voltage summing/subtraction and comparison functions via current operation. The speed of this unconventional comparator drastically improved since there is no feedback loop and coupling capacitors needed to maintain the linearity. The linear input range is also enlarged by the common mode compression. The principle, design
OBJECTIVES: To assess the extent to which knee extensor strength and weight in adolescence are associated with knee osteoarthritis (OA) by middle age.METHODS: We studied a cohort of 40 121 men who at age 18 years in 1969/1970 underwent mandatory conscription in Sweden. We retrieved data on isometric knee extensor strength, weight, height, smoking, alcohol consumption, parental education and adult
Computer-based design analysis is nowadays a common activity in most development projects. Used for design evaluation, verification, validation, or as a support for design exploration, it fulfils an important support function for the engineering designer, thus making it essential to have an operationally efficient and effective integration between both the engineering design and design analysis ac
