The objectives of this study are to assess the perception of slipperiness, thermal comfort, and wearability of footwear used on icy surfaces, and the anti-slip effect of materials spread on ice using outdoor walking trials. Twenty-five subjects wore four types of footwear walking on five different icy surfaces. Five-point rating scale was used recording wearer's perception. The results showed that

Additive manufacturing (AM), which was first applied for rapid prototyping, is now becoming a real option for small-batch production of final products. Further expansion of AM is closely correlated to production costs. AM can only become competitive to traditional manufacturing methods if a product is designed for AM already from the beginning as it is an expensive technology that should only be a

In addition to a rise in global air and water mean temperatures, extreme climate events such as heat waves are increasing in frequency, intensity, and duration in many regions of the globe. Developing a mechanistic understanding of the impacts of heat waves on key ecosystem processes and how they differ from just an increase in mean temperatures is therefore of utmost importance for adaptive manag

As the quest for knowledge translation from research to practice and policy contexts is growing stronger, researchers need to develop strategies for synthesizing research findings. Since home environments constitute an important context for the delivery of health care and social services to older adults and people aging with disabilities, research in this field can serve as an example for such end

REST is a transcriptional repressor that targets a group of neuronal genes in non-neuronal cells. In embryonic stem (ES) cells, REST has been implicated in controlling the expression of transcription factor genes that are crucial for lineage determination and for maintaining ES cell potential. Here, we asked whether REST directly regulates neural-specifying genes in mouse ES cells using siRNA-medi

Uppsatsen syftar till att söka förståelse till varför tvister mellan fackförbund om vem som ska teckna kollektivavtal uppstår. Arbetsmarknadernas parter är i allmänhet ense om att det som regel bör finnas ett kollektivavtal på varje avtalsområde. Kollektivavtalets speciella rättsverkningar gör det viktigt för fackförbunden att vara avtalspart i ett kollektivavtal. Kollektivavtalet sätter i stor utThe aim of this essay is to seek understanding about why conflicts appear between trade unions regarding which one of them should sign the collective agreement in the workplace. The labour market parties are in general in an agreement that there should only be one applicable collective agreement in every area of work. The unique effects of the collective agreement make it crucial for the trade uni

Rapporten behandlar arbetsmiljön vid termisk ogräsbekämpning. Metoden innebär att ogräset hettas upp med hjälp av gaslågor. Både stora fordonsburna och mindre handdrivna används. Det som från arbetsmiljösynpunkt är speciellt med metoden är de risker som är förknippade med gasolanvändningen. De allvarligaste problemen med de aggregat som studerats har varit heta och oskyddade plåtar, heta avgaser o

In temperate regions, many vector-borne parasites maximise their transmission prospects by adjusting reproduction to seasonal cycles of host susceptibility and vector availability. Nevertheless, in these regions there are areas where environmental conditions are favourable throughout the year, so that parasites could benefit from a year-round transmission strategy. We analysed how different transm

Current trends show that the number of people affected by natural disasters is likely to increase in coming decades. Today, more than half the world's population lives in cities and the number is expected to rise in the future. To make cities safe is therefore vital. Making Cities Resilient is an ongoing global campaign in the area of disaster risk reduction and aims to build resilient cities

The aim of this qualitative study was to investigate the social identity of students at upper secondary school for physically disabled students. The youths I drew my attention to suffered from severe physical disabilities and therefore received specially adapted education in small classes, but integrated at an ordinary upper secondary school. By "social identity" I mean how the students

The purpose of this study is to evaluate the safety of people located in discotheques in case of fire. A quantitative fire riskanalysis (QRA) for three different types of discotheques is carried out. The analysis is based on performance based codes from which fire protection alternatives are analysed. The results of the quantitative fire riskanalysis are described as risk profiles and average risk

Exposure to urban air pollution during early pregnancy is associated with increased risk for adverse pregnancy outcomes, such as preeclampsia (PE), and there is an urgent need to understand how air pollution affects biological mechanisms in the placenta. Hofbauer cells (HBCs) are fetal placental macrophages that regulate immune tolerance in the placenta. They are normally polarized towards an anti

Ett antal studier har visat att buller har negativa hälsoeffekter (Barregård et al. 2005; Rosvall et al. 2009; Nilsson, Eriksson & Palmqvist 2009). Exempel på problem som kan uppstå på grund av buller är sömnsvårigheter, hjärt- och kärlsjukdomar, minskad inlärning och reducerad kognitiv förmåga (Berglund, Lindvall & Schwela 1999). Dessa typer av hälsoproblem leder till lidande för den enskNoise has negative health effects according to a number of studies (Barregård et al. 2005; Rosvall et al. 2009; Nilsson, Eriksson & Palmqvist 2009). Example of problems that can occur from exposure to noise is sleeping disturbances, heart diseases, lessened learning and reduced cognitive performance (Berglund, Lindvall & Schwela 1999). This kind of problems cause suffering on a personal le

The purpose of this study is to examine how social service handles incorrect information about them that is spreading on social media. This study is based on a qualitative method. In order to achieve the purpose of this work, the focus has been on the unit of child protection services and seven social workers have been interviewed. The study shows that social workers only handle incorrect informat

When a country liberalizes trade through lowering taxes on imports, it stands before a number of challenges. Recovering lost trade tax revenue is one of them. Cape Verde is one of the countries that are currently negotiating an Economic Partnership Agreement with the EU and studies predict that the tariff reductions resulting from the agreement may have a severe impact on Cape Verde’s government r

Quantitative evaluations are valuable in the strive for improvements and asserting quality. However, the field of Command & Control (C2) evaluations are hard to navigate, and it is difficult to find the correct measurement for a specific situation. A comprehensive Scoping Study was made concerning measurements of C2 performance and effectiveness. A lack of an existing appropriate framework for
