F?RS?LJNING AV OCH INST?LLNING TILL FR?MMANDE V?XTER I TR?DG?RDSBRANSCHEN

Alien plants that have intentionally been introduced to an area for cultivation in public or private gardens constitute the primary pathway of introduction for invasive alien species that spread into nature. Garden owners want species that have satisfying characteristics, these characteristics are often also linked to plant invasiveness. Thus, the horticulture industry plays an important role by making scientifically based decisions and phasing out invasive plants and replacing them with alternative species with satisfying characteristics, but low risks of becoming invasive. This thesis aimed to examine the sale of and the attitudes towards alien plants in the horticulture industry in Sweden. Alien terrestrial plants identified to have a severe risk, high risk or potentially high risk of spreading and becoming invasive according to ArtDatabankens assessment, were examined to see if they were for sale.

Parametriserad 3D-modell av cyklon : Parametrisering av en 3D-modell av ett cyklonfilter i SolidWorks för snabb framtagning av nya konstruktioner till Outotec Skellefteå

This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

Traktkilars inverkan på hovens glukos- och laktatmetabolism :

The equine hoof is often manipulated in purpose to achieve a better stride or to reduce the weight on damaged tissue. The living tissue in the hoof can?t store energy as glycogen and is therefore depending on a continuous supply of glucose for its energy production. The purpose of the study was to determine if wedging (i.e. elevating) the heel could influence the hooves glucose and lactate consumption/production. Five standardbred horses were trained to trot on a treadmill without getting physical or mentally tired.

Rullarmering - Ett rationellt sätt att armera

This is a degree project performed at Halmstad University in Sweden on the subject carpet ofreinforcement. This project is developed in association with Celsa Steel Service in Halmstad.The purpose of this report is to investigate how much time that can be saved if carpet ofreinforcement is used instead of the traditional way to work with reinforcement and seewhat kind of parameters that is important between the choices. We are also going to seehow this product affects the situation for reinforcement workers from an ergonomic point ofview.Carpet of reinforcement is made by straight reinforcement?s bars that are welded togetherwith steel bands. These rolls are made at a factory with a machine that welds together thebars in determined centre distance, with desired dimensions after the constructionengineers? blueprints.

Kommunal redovisning : Ett verktyg för kommunikation och ansvarsutkrävande

Background: Previous studies have shown that intuition occurs in decision making in small enterprises. However, these studies have not illuminated which decision attributes leads to intuitive decision making.Purpose:The purpose with this study is to contribute with an increased understanding of which decision attributes leads managers in small enterprises to use intuition in decision making and why these decisions attributes have an impact on the role of intuition. The follow-ing research question will be answered in our study: Which decision attributes leads to intui-tive decision making in small enterprises, and why?Method: To answer the research question we have conducted semi structural interviews with managers in small enterprises to achieve a deeper understanding of the role of intuition. We have also used a method called Visual Card Sorting as a complement to the semi structural interviews.Result/conclusion: The result of our study indicates that the relevance and the uncertainty of a decision have the greatest significance in the use of intuition in decision making in small enterprises.

Optimering av SNCR-system i en biobränsleeldad panna : möjligheter till minskade NOx-utsläpp för ENA Energi

Emission of nitrogen oxides as well as carbon monoxides is an inevitable result of combustion. A Swedish law "Law of environmental fee for emissions of nitrogen oxides as a result of energy production" (lagen om miljöavgift på utsläpp av kväveoxider vid energiproduktion (SFS 1990:613)) controls the emission of NOx from energy production by a system of fees. The system has resulted in a strong approach toward less emissions of NOx among the energy production plants. High emission levels, today exceeding 52 mg/MJsupplied fuel, leads to costs for energy production companies. This paper examines possibilities to reduce the emissions of NOx by optimization of the SNCR-technique in a biofuel fired heat and power plant.

Utveckling av en ytmonterad fördelningsmätare som underlag för individuell debitering av vattenförbrukning i fastigheter

The master thesis, conducted at Metrima AB, concerns the development of a non-intrusivedistribution meter as a basis for individual tap water billing in apartments.The project is conducted in response to the market interest in individual tap water billing inapartments as an answer to environmental concerns regarding water consumption. Due to thehigh installation cost of traditional water meters, a new method of determining waterconsumption, without having to cut water pipes, is proposed.The proposed method distributes the total water consumption for an apartment complex toindividual apartments according to distribution meters, measuring water run-time, in eachapartment. The water run-time is estimated by measuring the water pipe?s outward vibrationsand temperature changes.A test environment was established and a prototype built, using a tilt- and vibration sensor forvibration sensing and a precision temperature sensor to measure temperature changes. As bothsensors work well in the test environment, further testing was done in 3 apartments for aduration of 5 days.

This report is written on commission by WSP Acoustics. The report studies the outdoor sound levels on school yards in Stockholm. The questions given by the company to be answered was what are the actual sound levels at diffrent school yards with low traffic noise and how can you construct a facade element that reduces the sound level from the outside and meet the indoor requirements. Mesurements for four hours was done at eight schools set north and south of the city centre. The measurement period included one school break and one lunch break.

En jämförelse av RDF och avfall som förbränningsbränsle

In the EU the amount of waste increased by 14 percent during the years 2000 to 2010. EU?s target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective.

Lammproduktionens ekonomiska påverkan av MTR :

The Swedish consumption of lamb a increasing, and today we yearly eat a kilo of lamb per person each year. As a consequence the Swedish degree of self production according to lamb is steadily decreasing, and is today about 39 %.Today Swedish Meats is now cooperating with the Swedish lamb breeders organisation to raise that percentage. At the same time the European Union presents a new agricultural reform, the MTR (Mid Term Review). The shape of this new reform is not yet fully known, but the general policy has been more or less outlined. The new reform is split into three propositions: the farm model, the regional model and the mixed model.

FYSISK INAKTIVITET OCH STILLASITTANDE BLAND BARN OCH UNGA I GRUNDSKOLAN

Children and youth inactivity and sedentary at school is increasing. This means that some of the students have a significant unhealthy lifestyle with physical inactivity, which in turn implies risks of suffering from various diseases, including obesity, type 2 diabetes and cardiovascular disease, all related to a sedentary lifestyle. To prevent illness, it is important that children and young people early get a positive attitude towards physical activity.The purpose of this study was to study the causes of child and adolescent physical inactivity in school, based on teachers 'and parents' perspectives.A qualitative research has been selected. To achieve the study objectives, the author has conducted seven semi-structured interviews, with an appropriate choice of five teachers and two parents with children in school. Data was analyzed with a manifest content analysis.The results show that teachers and parents felt that physical activity is a protective factor for children's health.

Anestesi och intensivvårdssjuksköterskans hantering av mekanisk ventilation : - en litteraturstudie om minskning av atelektasbildning och förebyggande av komplikationer

Background Atelectasis is a commun respiratory complication related to general anesthesia and may contribute to pneumonia and acute respiratory failure. Atelectasis apear within 10 minutes after anesthetization and occur in 90% or more anesthezied patients regardless of age and gender. The aim of this study was to indentify if there are any evidence for which methods are ultimate or are most efficacious to reduce and prevent the formation of atelectasis.                                                                                                          Methods This study is a descriptive litterature study where 28 scientific studies have been indentified for review and analysis.                                                                                                               ResultsThe use of 100% oxygen during the induction of anesthesia favors the developement of atelectasis. This can be prevented by preoxygenation with oxygen content of 100% combined with a PEEP of 6-10 cmH2O. When free airway is secured, oxygenation with 100% was found to be unnecessary.

Användning av WHO:s checklista för säkerhet vid operationer och operationssjuksköterskans medverkan.

Background: Surgical complications has been the main cause of medical injuries and deaths worldwide. In 2008 WHO developed the checklist for safe surgery to reduce the number of surgical complications. The objective of the checklist is to strengthen already established safety routines and contribute to better cooperation and communication. Research shows that compliance to the checklist is deficient, which can affect patient safety.Aim: The aim was to study the extent to which theatre nurses participate in the use of the checklist.Method: Observational study was conducted with a descriptive design and quantitative approach. 24 observations were carried out with aid of an observation protocol of two surgical units at a hospital in central Sweden.Result: The results showed that Timeout initiated widely but compliance to all items was considerably lower.

Effekter av taktil beröringsmassage till patienter med smärta, oro och ångest.

BackgroundWhen women have breast pain this usually is not associated with myocardial infarction, which results in that they get less attention and wrong treatment. The nurse has an important role in informing and educating patients and families during hospitalization, which is usually short. Continuous training, written information and repetition for patient and family throughout the hospital stay are of considerable importance to clarify that the patient understands and to reduce the anxiety of being discharged.AimThe aim is to describe nurses' experiences of caring for older women with myocardial infarction.MethodsA qualitative method was used. The collection of data was done by six interviews with nurses in geriatric care and elderly care. Dataset has been processed based on a content analysis and divided into subcategories and main categories using meaningful units.ResultsNot having knowledge of older women with myocardial infarction was expressed as frustrating and nurses described how they were afraid to ask their colleagues.
