Surveillance cameras are vital in the nuclear power industry where the reactor equipment must constantly be kept under surveillance to maintain safety. Constant monitoring is however difficult due to the highly radioactive environment, which cause cameras to malfunction and eventually break. Malfunction typically manifests itself as quality degradation of the image from the cameras. Initially, tem
The bike helmet is certainly a topic of current interest. From January the 1st 2005 it is mandated by law that children under 15 years old must use bike helmet when biking or being given a lift on a bike. There is an ongoing debate about the next step, to develop the law on bike helmet to apply for adult bicyclists as well. If a law like this would be established, the request on bike helmets would
BACKGROUND: Continued professional development (CPD) is required for updated skills and knowledge. This study evaluates the efficacy of a CPD programme for mainstream school teachers.AIMS: In an 11-week intervention programme, speech-language therapists (SLTs) presented the participating teachers with whole-class teaching techniques aimed at creating a language and communication-supporting classro
The use of drugs has increased among young people in Sweden and it is the social workers responsibility to both support and control those who use drugs. According to Swedish law, all illegal drug use is viewed as abuse. However it has been shown that the concept of drug abuse is more complex and that it is not a guarantee that everyone who experiments with drugs will fall into long term use. The p
Occupational engagement is a vital factor in people's lives since it has been shown to be important for health and well-being. Community-based day centers (DCs), both meeting place-oriented and work-oriented ones, are common service alternatives in many western countries for enabling engagement in productive and leisure occupations among people with psychiatric disabilities. Little is, however, kn
Climate warming in the Swedish sub-Arctic since 2000 has reached a level at which statistical analysis shows for the first time that current warming has exceeded that in the late 1930' s and early 1940' s, and has significantly crossed the 0 degrees C mean annual temperature threshold which causes many cryospheric and ecological impacts. The accelerating temperature increase trend has driven simil
Forests are important from many perspectives. Forestry delivers products such as timber, fiber and fuel; forests are also important for recreational activities as well as for the global carbon balance. Consequently, it is important to develop methods that enable efficient monitoring of disturbances, such as insect attacks, over vast forested areas. These methods can be based on remote sensing, sin
Background: Theory of warehouse operation are a well explored area but it seems that warehouse manager have a hard time to understand what solutions to adapt to improve their warehouse. Theory of Constraints(ToC) are a young philosophy regarding improvements work that have been employed to many different business areas. Warehouse manager would need a method to evaluate what solutions to implement
Colorectal cancer (CRC) is the third most common cancer worldwide with more than 700,000 deaths every year. Prognosis mostly depends on disease stage at diagnosis, however, outcome may vary considerably even within the same stage. Thus, there is a great need for new prognostic biomarkers to better identify patients with a high risk of developing metastases and select right patients for adjuvant tr
Knowledge of the forest biomass and its change in time is crucial to understanding the carbon cycle and its interactions with climate change. LiDAR (Light Detection and Ranging) technology, in this respect, has proven to be a valuable tool, providing reliable estimates of aboveground biomass (AGB). The overall goal of this study was to develop a method for assessing AGB using a synergy of low poin
Resource availability and limiting factors for bacterial growth during early stages of soil development (8-138 years) were studied along a chronosequence from the glacial forefield of the Damma glacier in the Swiss Alps. We determined bacterial growth (leucine incorporation) and we investigated which resource (C, N or P) limited bacterial growth in soils formed by the retreating glacier. The latte
This Master’s thesis aims to highlight the first decades of the Swedish archival society from a gender perspective. The timeframe of the research stretches from 1899, when the first Swedish National Archive’s regional archive was founded, to the 1960s, when the first women were employed as archivists. It includes the regional archives of Vadstena, Lund, Visby and Östersund. The theoretical basis f
Introduction: In recent years omni-channel retailing has been accepted and used by both physical and e-commerce retailers. In omni-channel retailing different channels are integrated. An effective and efficient distribution system is becoming more crucial. The core of the distribution system is warehousing that affects lead time and logistics cost. The main challenge is to handle large store reple
A wave atlas describing the monthly wave climate at 5 locations along the Swedish SE coast was desired. Using the WAM wave model to hindcast the waves between Jan 1st 2004 and Dec 31st 2009 the parameters significant wave height, direction of wave propagation and spectral wave peak period were extracted from the time series and assembled in a wave atlas. The model was forced with point source wind
Purpose: Western societies are currently facing major demographic changes, due to megatrends such as urbanization, ageing of the population, and migration. These disruptions placea lot of pressure on public services, and consequently on municipal facilities includingschools, day-care centres, and hospitals. The purpose of this study is to examine the potentialof modular facility solutions to respo
Evacuation is an important activity for reducing the number of casualties and amount of damage in disaster management. Evacuation planning is tackled as a spatial optimization problem. The decision-making process for evacuation involves high uncertainty, conflicting objectives, and spatial constraints. This study presents a Multi-Objective A
Cirka 1000 barn föds med hjärtfel i Sverige varje år och idag överlever de flesta och uppnår vuxen ålder. Det finns uppskattningsvis 2.3 miljoner vuxna med medfött hjärtfel i Europa idag, en siffra som förväntas öka. Samtidigt har prevalensen av patienter med komplexa medfödda hjärtfel också ökat de senaste 10 åren. Det finns således ett behov av att öka kunskapen om patofysiologin vid dessa sjukdAround 1000 children are born with a heart disease in Sweden every year and today most of these children survive and reach adult age. There are around 2.3 million grownups with congenital heart disease in Europe today, a number that is expected to continue to increase. Further, the prevalence of patients with complex malformations has been growing significantly the last 10 years. There is thus a n
Over the last few decades, the African Sahel has become thefocus of many studies regarding vegetation dynamics and theirrelationships with climate and people. This is because rainfalllimits the production of biomass in the region, a resource onwhich people are directly dependent for their livelihoods. In thisstudy, we utilized a remote-sensing approach to answering thefollowing two questions: (1)
Smartphones have become one of the main tools for travel information search, especially on site, during the trip. The use of mobile technologies and ubiquitous internet connectivity do not only allow tourists to access information anywhere, at any time, but have deep impacts on tourists’ behaviours and on their whole tourist experience.The study suggests an interpretation of tourists’ information
