Myndigheten och den ensamstående föräldern. En studie av ensamstående föräldrar med barn och deras behov
In this study we describe the needs of lone parents and how the authorities fulfill these needs. The needs contain both economic and social aspects, such as the access to an employment, childcare and the possibility to social activities. For the lone parents being able to work the childcare provision must improve and be available in a greater extent during non-traditional working hours. It is also required that the housing benefit ceiling is increased so that the parents may work more hours without risking the loss of the housing benefit. The statistic about the housing benefit which we present shows that many of those with a low income are lone parents.
Att leva med kroniskt obstruktiv lungsjukdom : Patienters beskrivning av sitt dagliga liv.
Background;Chronic obstructive pulmonary disease (COPD) is a lung disease characterized by airway obstruction. Common signs of COPD are the slow process and shortness of breath on exertion. The most important treatment is to quit smoking. Most nurses, regardless of where they work, will meet these patients, often when the patients are having respiratory disorders. Aim;the aim of this study was to illuminate how patients with COPD describe the daily life based on how he/she experience and cope with the disease.
Konditionsträning i värme för rökdykare - en pilotstudie
Endurance training in the heat for firefighters - a pilote study Acklimatisering är en psykologisk och fysisk process då en anpassning till en ny eller förändrad omgivning sker efter en regelbunden exponering till en viss miljö. Träning för att främja värmeacklimatisering för rökdykare förespråkas av arbetsskyddsstyrelsen. Syftet med denna studie var att undersöka om 6 veckors ergometercykling i bastu påverkar upplevd ansträngning, toleransen för värme och uthållighet vid rökdykningsövning. Testgruppen bestod av 7 rökdykare. Vår intervention bestod av 6 veckors ergometercykling i bastu vid 70ºC 2 gånger i veckan à 20 minuter.
AIS i havets och tankens strömmar : En etnografisk studie av nautikers användning av transpondersystemet AIS
An ethnographic study loosely informed by the theoretical framework of distributed cognition was carried out in order to describe how mariners have adopted the Automatic Identification System (AIS) in their work practice, or"made the technology their own". AIS is a transponder-based identification and communication system that allows ships to automatically identify and track each other. In addition to facilitating the identification and tracking of ships, objectives behind the introduction of AIS are to"simplify informational exchange", and"provide additional information to assist situation awareness". Participant observation and interviews were made at four different ships, as well as at two shore stations. A focus group was also held at a maritime conference.
Träd som berör : en intervjustudie om specifika träd i människors liv
There is no doubt about the significance of nature on the health of human beings. Not
only is the tree an element of nature that is of great value to our survival, it also serves as a valuable object and symbol of human beings? enjoyment and appreciation of the
environment. The purpose of this study is to present the relationship that a person may
have with a specific tree. Three women and two men are interviewed about their trees and
the places where they are located.
Svansbitning hos gris relaterat till individuell tillväxt och ras :
The purpose with this study was to find out if tailbiting pigs have a higher or lower daily weight gain than non-tailbiting pigs in the same pen before tailbitingbehaviour occur. The purpose was also to compare the occurrence of tailbiting between different breeds (Swedish Landrace, Yorkshire and Hampshire). Tailbiting among pigs has been a problem for pigfarmers a long time. Tailbiting means reduced animal welfare for the pig and economical loss for the farmer. The results of this study are based on statistical analyses.
Att knyta an eller bryta sig loss : Ungdomar och unga vuxna i psykodynamisk psykoterapi
Flera rapporter visar att unga människor i Sverige mår allt sämre psykiskt. De utvecklingspsykologiska processer som kännetecknar tonåren och de tidiga vuxenåren kan vara förenade med stora påfrestningar och därmed utgöra en risk för utvecklingen av psykisk ohälsa. Psykodynamisk psykoterapi med ungdomar och unga vuxna är en väletablerad behandlingsmetod för unga människor med psykiska problem, men trots detta är forskningsbasen begränsad. Syftet med föreliggande studie var att undersöka utfallet av psykodynamisk psykoterapi med 213 ungdomar och unga vuxna som bedrivits på Ericastiftelsen mellan åren 2004-2009. Deltagarnas funktionsnivå på CGAS- och GAF-skalorna samt självskattningar av symtom på SCL-90 jämfördes före och efter psykoterapi.
Hållbar växtnäringshantering i Stockholms län : En aktörsanalys
Plant nutrients are important for all life on earth and are also important as fertiliser infood production all over the world. Because of this, plant nutrients are of great valuebut they also bring problems. As an example, the loss of nitrogen and phosphorusfrom agriculture and urban society's sewage systems contributes to some of today?smajor problems in water environment. Another problem associated with plantnutrients is that finite recourses are used in the production of mineral fertilizers.
Bremsningens effekter hos häst : utvärderat med hjälp av termografi, hormonanalyser och hematologi
Twitching is frequently used in horse management because of its sedating and pain-relieving effects. In this study, the effects on the horse?s nervous system by twitching were investigated by thermography of the skin temperature. The temperature is regulated by the sympathetic nervous system through postganglionic sfincters at the capillaries of the skin. The effects on the endocrine activity have also been studied by the measuring of ACTH and cortisol in blood plasma.
Energikartläggning och driftoptimering genom behovsstyrning i befintlig fastighet
Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.
Utredning av värmepump med fjärrvärmespets
Det här är ett examensarbete som handlar om en fastighet som står på Norra Kungsgatan 37-43 som har både en värmepump och fjärrvärme för uppvärmning. Värmepumpen används i första hand och fjärrvärmen används som spets när värmepumpen inte räcker till. Detta är en ganska ovanlig kombination. Syftet med arbetet är att ta reda på om detta är en bra lösning och om lösningen är lönsam. För att få fram hur stort fastighetens energibehov är så görs beräkningar utifrån fjärrvärmedata från tidigare år samt en gammal värmepump som är utbytt sedan 2011.
Tillagning i mikrovågsugn och dess effekt på livsmedel : En jämförelse med konventionell tillagning
Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition.
This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking.
The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.
Environmental variables determining the occurrence of the red-listed Carbonicola anthracophila and C. myrmecina in boreal forests
The global biodiversity loss is mainly due to human activities such as an intensification of forestry. Boreal forest ecosystems in Fennoscandia are characterized by disturbances such as forest fires, storms and floods. However, industrial forestry practices suppress forest fires and change the landscape, leading to a loss of habitats and associated species. Particularly lichen species with slow adaptation abilities and a strong substrate specificity face an extinction debt in boreal forests since their substrates are long-lived but no longer created. In this study the species-substrate relationship of two red-listed forest-fire dependent lichen species Carbon-icola anthracophila and C.

Tillståndsbaserat underhåll till sjöss : Vad föranleder den begränsade användningen av tillståndsbaserat underhåll (CBM) till sjöss?
Today, maintenance is a big part of the daily life on board ships. It is also one of the bigger expenses a shipping company has and without any loss of quality tries to run as economically advantageous as possible. In the hunt for economical savings the shore-based industry has subsequently applied the use of condition based maintenance, CBM, were a component is maintained according to its actual state. This leads to a reduction of maintenance costs since no parts are unnecessarily replaced. However, within the maritime sector a periodical maintenance is still the most commonly used maintenance system.The purpose of this paper is to chart the factors that are the reason for the low implementation of CBM on board the Swedish merchant fleet's ships.
