Framtidens stadsträd för en fungerande grönstruktur
The effect of climate change places demands on how we build cities. Cities have to be built denser to meet the objectives of sustainability but as a result of this densification city green areas are at risk of exploitationand disappearing. The question this raises is whether there has to be an opposition between a dense and a green city?Urban trees are playing a very important role in cities. They stand as the major part of the vegetation in citieswhich are otherwise dominated with concrete and stone.
Fosforgödslingseffektivitet i långliggande bördighetsförsök
Rapid population growth and the fact that phosphorous is a limited resource implies that the question regarding an efficient use of phosphorus is of great importance, and consequently,that the phosphorous use efficiency should be as high as possible. The view on phosphorous use efficiency, and how this is calculated, has varied over time. This has had great implications on what type of research that has been conducted, which have resulted in an
inconsistency between the academic?s view on the subject and recommendations received by farmers. The purpose of this paper is to calculate the phosphorus use efficiency in the Swedish long term fertility experiments.
BeAKKta : ett kommunikationshjälpmedel som möter behoven av djupare kommunikation hos personer med autism
A vulnerable group in society is people with ASD (autism spectrum disorders) or autism. This group seems to increase, mainly due to genetic factors but also environmental problems. Medical research has accelerated in the U.S. and Europe. The biggest problem for people with disabilities is the inability to communicate, both verbally and socially.
Hur uppnår vi god inomhusmiljö i förskolan idag?
Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.

Also, the new product?s production mustn?t be more costlythan today and the included materials and components must be obtainable from within theBolivian national borders where the product is currently produced. During the project, certainadvantages with a more efficient, and, above all, a more moderately priced product, werediscovered.
Spridning av släckvattenpartiklar : En studie på spridning av partiklar genererade från brand
During a fire large amounts of particles and unhealthy agents occur. Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.
Kvalitetsstyrning i grundskolan : Hur relaterar skolor till begreppet kund, måluppfyllelse och kvalitet? En studie av tio grundskolors kvalitetsredovisningar.
Since the nineties the words customer, effectiveness and quality have become part of everyday school life. Municipalities? makes regular customer surveys to measure both independent schools as municipal schools ' quality. A common method for customer research and background studies is that parents and students are asked to respond to simple Web-based surveys. Customer satisfaction and/or customer dissatisfaction options are presented in tabular form, based on the percentage that expresses a particular position within a query.
Produktion av Pyrolysolja från kvistrejekt
Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting. Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.
Automatiserad mätning av kvalité : Varför är inte all mätningautomatiserad?
AbstractThis bachelor?s thesis at the Department of Production Engineering at the Royal Institute of Technology in Stockholm deals with the subject of automated metrology. The degree of automation of tasks within production has been a growing trend but the measurement of quality has not followed the same trend. The main thesis follows:What incentives are there to automate the measurement of quality in production?What factors are crucial and why are not all metrology automated?The thesis comes along with a number of sub-queries and delimitations.The working method includes both theoretical and empirical studies.
Fermented sausage : product development at Lindell's Gårdsslakteri
Product development is a risky business; many products never yield profit, but it is also ne-cessary for a company?s survival in a competitive business where the costumers change their requests constantly. Consumer-led product development is developed from the wish to fill the consumer?s needs and expectations and thereby be more likely to succeed. Lindell?s Gårdsslakteri AB is a local slaughter and meat processor in Västergötland.
Strålbenshälta hos häst - vilka är de genetiska faktorerna bakom detta hälsoproblem?
Denna litteraturstudie behandlar strålbenshälta hos häst, även känd som Navicular disease (ND). Studien beskriver sjukdomen och dess karaktäristiska drag, samt belyser de två huvudsakliga teorierna om den bakomliggande orsaken till insjuknandet. Det finns tydliga inklusions- och exklusionskriterier, vilka är viktiga för att kunna göra en omfattande hältutredning och för att kunna ställa rätt diagnos, som är betydande för att ge rätt behandling. Litteraturstudien belyser även det faktum att hästar drabbade av ND har visat sig ha högre intramedullärt tryck i strålbenet, samt vilka genetiska riskfaktorer som visat sig vara kopplade till sjukdomen. De genetiska defekter som behandlas är röntgenförändringar i strålbenskonturen (RAC) och strålbensstrukturen (RAS), samt utvecklandet av deformerade näringsfåror i strålbenet (DCS).
PARAMETRISERAD DESIGN APPLICERAD PÅ EN MOTORSÅGSKEDJA
The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.
Print quality study of a laboratory offset press
PAPRO operates within the Forest Research company and their mission is to develop value-addingindustry solutions. At present there are no good ways for mills to easily test the printing quality on newsprintpaper. There is a great need for a fast way to do this on different paper qualities; with a laboratory-offset press this can be both a time and money saving method. At PAPRO Forest Research, NewZealand, a laboratory offset press has been developed and designed, during the past seven years, concerningthis issue. Earlier projects were made concerning the press, e.g.
A comparison of two certification schemes for dairy cow welfare in relation to resource-based, management-based and animal-based measures
Traditionally risk-based measures have been used to assess animal welfare in legislation and certification schemes. With increased knowledge and research, debate today tends to focus on and advocate the use of animal-based measures. However this is not a panacea for welfare and the most sound conclusion should be that assessment of animal welfare needs both. The aim of this thesis is to identify the points that need to be taken into consideration to find the optimal balance in the use of input and outcome measures according to the aim of the assessment and how these should be applied when designing a certification scheme? To answer this, a comparison of the use of resource-based, management-based and animal-based measures in two certification schemes for dairy cow welfare, Freedom Food (UK) and Svenskt Sigill (SWE), was made.
