Trä som fasadmaterial ? behandling och beständighet
Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.
Distriktsköterskans arbete med och reflektioner kring behandlingen av vuxna patienter med övervikt och fetma : En kvalitativ intervjustudie med distriktssköterskor på landstingsdrivna vårdcentraler i Uppsala län
Övervikt och fetma är ett växande problem i Sverige och delar av världen. Det är en riskfaktor för andra somatiska sjukdomar och har en negativ inverkan på livskvalitén. Syftet med denna studie var att beskriva distriktsköterskors arbete med och reflektioner kring behandlingen av vuxna patienter med övervikt och fetma. Studien var av kvalitativ ansats med deskriptiv design och genomfördes genom semistrukturerade intervjuer med åtta distriktssköterskor på landstingsdrivna vårdcentraler i Uppsala län. Resultatet av studien visade att mätvärden och samtal var viktiga verktyg för att distriktssköterskorna ska kunna identifiera patientens övervikt eller fetma.
Palliativ vård i hemsjukvården : En litteraturstudie om patienters, anhörigas och sjuksköterskors erfarenheter
Bakgrund: Att få kunna vårdas och dö hemma i en familjär och välkänd miljö innebär för de allra flesta en känsla av trygghet. För många anhöriga är det självklart att leva nära den döende och ta ansvar för omvårdnaden. Ur ett systemteoretiskt perspektiv kan familjen liknas vid en mobil, vid obalans påverkas alla familjemedlemmar. Syftet med studien var att belysa patientens, anhörigas och sjuksköterskors erfarenheter av palliativ vård i hemmet för att få en ökad förståelse för sjuksköterskors roll i detta sammanhang. Metod: Litteraturstudie där tidigare forskning i ämnet undersökts och sammanställts.
Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos
Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.
Kvalitetssäkring av markberednings- och planteringsuppföljning hos SCA Skog AB Jämtlands skogsförvaltning :
Quality assurance means to systematically work for better understanding of the customers needs, demands and expectations. The goal for this study was to investigate how quality can be assured in the job follow up that is made by forestry contractors after soil scarification and planting. The study consisted of a description over the current follow up process at SCA forest AB Jämtlands forest administration, analysis of current follow up situation and an investigation of follow up process made by contractors in other line of business.
The first step was a statistical comparison where the own follow up made by contractors were compared with follow up made by SCA them selves over 100 stands. Two soil scarification contractors and two planting contractors carried out the silvicultural measures. The results showed that significant differences between a number of quality factors measured, for example number of approved plants or approved scarification points, average score on stand and number of totally planted plants.
Solenergi : en lönsam investering för ett lantbruk?
A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.
Medling enligt föräldrabalken (FB) : En studie om domarnas syn på medling
This paper is based on a study seeking answers to questions about how the judges at district courts look at mediation as a way to deal with custody and visitation disputes between parents who do not live together. The questions posed in this study are: When is a mediator appointed? What result do judges expect to mediation? What do the judges say about how a mediator should work? What are the judge?s opinions about the lawyer?s role in these cases? Finally, how do the judges define the children?s needs and how do the judges check that the solution is best for the child? The study also aims to compile theories of mediation, to create new knowledge and to possibly develop new research questions related to mediation. The study is a qualitative case study with law sociological and abductive approach. The interviewed judges all have a lot of experience in family law cases.
Cooking banana farming system in rural Uganda : a comparison between agroforestry systems and non agroforestry systems
The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today.
This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.
Foraging and anti-predation behavior of Thomson?s gazelles (Gazella thomsoni) and Grant?s gazelles (Gazella granti) at a waterhole
Prey species make behavioral decisions to reduce the perceived risk of predation and the time spent vulnerable to predation. Behavioral responses to predators are for example selection of specific habitat types and the presence of predators influence individual vigilance. Furthermore, there is a variation in feeding niches with different herbivores focusing their foraging effort on different vegetation types which is also expected to affect the choice of habitat. Behavioral data on anti-predation and foraging behavior at on waterhole is collected from Thomson?s and Grant?s gazelles at Ol Pejeta Conservancy (0°00?N, 36°56?E) located in semiarid bushed grassland in Laikipia district of central Kenya.
Distriktssköterskors reflektioner och upplevelser av sin roll i relation till närstående vid palliativ vård i hemmet : En kvalitativ studie
Palliativ vård definieras enligt Världshälsoorganisationen som ett förhållningssätt som ska syfta till att förbättra livskvaliteten för patienter och deras familjer som drabbas av problem som kan uppstå vid livshotande sjukdom. Det blir allt vanligare att människor med obotliga sjukdomar vårdas hemma den sista tiden i livet och några av förutsättningarna för att vårdas hemma är att det finns fungerande stöd från hemsjukvården samt att närstående är delaktiga i vården. Syftet med studien var att beskriva distriktssköterkans reflektioner och upplevelser av sin egen roll i relationen till närstående vid palliativ vård i hemmet. Studien har en beskrivande design med kvalitativ ansats. Det är en intervjustudie genomförd med åtta distriktssköterskor som arbetade med hemsjukvård och palliativ vård i hemmet.
Stöd till mödrar som avbryter amningen - Distriktssköterskans perspektiv : en kvalitativ intervjustudie
Bakgrund: Fördelarna med amning är välkända men trots det avbryter många svenska mödrar sin amning tidigare. Att avbryta amningen kan för en del mödrar vara problematisk och leda till skuldkänslor. Tidigare studier visar att brister i stödet ökar känslor av frustration, förvirring och tvivel hos mödrarna. Syfte: Att beskriva vilken erfarenhet distriktssköterskan inom barnhälsovården har av att stödja mödrar som valt att avbryta amningen. Metod: Studien har en kvalitativ ansats där semistrukturerade intervjuer genomfördes med tio distriktssköterskor.
Teknisk undersökning : Rötgaskammare för småskalig biogasproduktion
Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.
Utvärdering av möjligheten att tillvarata energi ur processvatten : En undersökning gjort vid Olofsfors AB på uppdrag av UMIA AB.
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Den globala uppvärmningen : vad kommer att hända med morgondagens värld?
Mankind faces a serious threat. Its activities, for example the burning of fossil fuels, have led to an enhancement of the greenhouse effect - something that has given rise to a global warming. The climate is becoming warmer, a change that has important effects on the nature as well as for humans and their society. Sea level rising, extreme temperatures are becoming more common, glaciers and other ice caps melt and storms becomes more intense when they appear. The main cause is the emission of greenhouse gases into the atmosphere - carbon dioxide in particular.
Grannskapstorg som fenomen - med fallstudien Axel Dahlströms torg
In the 1940s the Swedish town planning was inspired by the English city development with the concepts of neighbourhood and community planning. In order to promote democratic development and solidarity the ideal would be to create community centers with full service. Community centers are part of the building of the suburbs during the postwar period. The buildings in Sweden from 1940 - and -50s were built with the intentions to be good homes for all regardless of income, class and status. Collective solutions to individual problems were characteristic of the Swedish policy during this time.
