Handlingsplan för rening av dagvatten från hårt trafikerade gator i Örebro

The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids. Included the overall study, some smaller areas has also been calculated for the possibility to remove pollutants.The work also includes calculation for three different areas for stormwater treatment.

Risk för exponering av växtskyddsmedel i växthusmiljö

Plant Protection Products (PPP) used in the horticulture industry can be both chemical and biological. They are used for weeds (herbicides), insects (insecticides), and fungi (fungicides) and as growth retarders.Many horticulture workers get in touch with plants, treated with PPPs and many of these don?t use any protective equipment.The aim of this project is to illustrate the work environment hazards for staff working with greenhouse pot plants, after they have been sprayed.The method used was observations of the operations for packing plants. I studied the operations and took notes of how operations were performed and what protective equipment they used. I also took photos and asked questions.A literature study completed the observations.

Support Vector Machines for Classification applied to Facial Expression Analysis and Remote Sensing

The subject of this thesis is the application of Support Vector Machines on two totally different applications, facial expressions recognition and remote sensing.The basic idea of kernel algorithms is to transpose input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These operations in the feature space can be expressed in terms of input data thanks to the kernel functions. Support Vector Machines is a classifier using this kernel method by computing, in the feature space and on basis of examples of the different classes, hyperplanes that separate the classes. The hyperplanes in the feature space correspond to non linear surfaces in the input space.Concerning facial expressions, the aim is to train and test a classifier able to recognise, on basis of some pictures of faces, which emotion (among these six ones: anger, disgust, fear, joy, sad, and surprise) that is expressed by the person in the picture. In this application, each picture has to be seen has a point in an N-dimensional space where N is the number of pixels in the image.The second application is the detection of camouflage nets hidden in vegetation using a hyperspectral image taken by an aircraft.

Utvecklingsprinciper för eftersatta naturlika dungar och ridåer

Nature-like plantations are areas that, by today?s maintenance procedure usually gains low prioritiy and are forgotten. Most nature-like plantations are currently disadvantaged and have in many cases grown up and formed dense,impenetrable and brushwoody green volumes. These green volumes is rarely used, but usually only fills out gap surfaces. With proper care nature-like plantations can become health promoting environments in the increasinglyhardened urban environments.How vegetation systems work and how trees and shrubs interact is dependent on many factors.

Analys av temperament hos långhårig collie

The majority of all collie owners in Sweden are satisfied with their dog and choice of breed and may well consider having another one. This was found in a survey that collie owners who owned a collie between the years 1999-2009 had the opportunity to fill in from May to December 2010. In the questionnaire there were three questions included where the owners could answer whether they were satisfied or not with their dog. These questions were: * Do you think the temperament of your dog is well suited for your way of life and the goal you have with your dog? * Would you be willing to get another dog in the future? * If you were to get another dog, would you consider a rough collie? When the answer to these three questions were compared with the dogs behavior, as described in the other questions in the survey, it seemed that it was mainly the fearfulness of the dog that differed between owners who were satisfied with their dogs and those who were not.

Processutveckling av borstgradning

During the milling of Sandvik Coromant?s world leading Drill with replaceable inserts,the CoroDrill880©, burrs appear around the milled surfaces. The burrs are removedusing different methods, one of which is deburring with special brushing machines thatare integrated into milling cells. The machines of the type Sinjet, use a Siemensguidance system. The deburring results are not satisfying and manual deburring isrequired afterwards.

Intelligent vattendesign : utformning av Gjutarplan i Kallhälls centrum

The thesis aims to be an informative study for landscape architects and hopes to contributeto an understanding of ways water can be used and managed at sites lacking open, greensurfaces.The title "intelligent water design" should evoke the reader?s thoughts concerning intelligentaspects of water. Text, images and the design proposition give hints about these aspects.In the first part of this thesis, various examples of water design are presented. The chosenexamples are all applicable in urban environments with a high percentage of impervioussurfaces.The second part examines Gjutarplan, an urban square in the centre of Kallhäll, in Järfälla,north of Stockholm. Gjutarplan is first framed in a geographical and historical context.

Oljefilmens tjocklek mellan kolvring och cylinderlopp

Hägglunds Drives in Mellansel, Sweden, manufacture radial piston hydraulic motors foremostwithin applications in the industry. These motors have several sliding contacts, one of these, isthe contact between piston ring and cylinder bore. The radial piston hydraulic motors advantageis to produce high torque in very low rotation velocity, this result in that the maximum slidingvelocity between piston ring and cylinder bore, during the whole stroke, is very low. Theconsequence of this low sliding velocity is that the contact between piston ring and cylinderbore, during the whole stroke, is bound to the boundary lubrication regime. This result in, thatthe piston ring is exposed to wear, thus affect the service life of the complete hydraulic motor.To minimize wear of piston ring, it is essential to determine the oil film thickness between thepiston ring and cylinder bore.

Skallet från forntiden : en osteologisk analys av hundben från stenålderslokalerna Hemmor och Gullrum på Gotland samt en teoretisk studie av hundens rituella och funktionella roll under neolitikum

The bark from prehistory ? an osteological analysis on dog bones from the Stone Age settlements of Hemmor and Gullrum at Gotland and a theoretic study of the secular and sacred roles of the dog during the Neolithic.Dog bones from two Pitted Ware Culture (around 2500 BC) settlements, Hemmor in När parish and Gullrum in Näs parish/Havdhem parish, at southern Gotland, Sweden are analyzed. The analysis contains a study of age, withers height and size estimation as well as skeletal changes and pathologies. The attempt of the analysis is to highlight the secular and sacred role of the dog during the Neolithic at Gotland. The dog bones were collected during excavations in the years 1890 and 1903 and were found across the entire surfaces of the settlements.Although there were no specific dog breeds during the Stone Age, the dogs at Hemmor and Gullrum show a wide range of size (withers height spans from 39,74 cm to 56,47 cm) and may therefore have been used for different purposes depending on their size.

Svartgran ? ett alternativ när allt ser mörkt ut? : en kartmodell för att visa lämpliga ståndorter för odling av svartgran

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

New Generation Surface treatment for tools : A preliminary study

The surface finishing technique called black oxidation is currently being used on thetool holders made of low alloyed tool steel produced by Sandvik Coromant. Blackoxidation isn?t considered a sufficient technique because it doesn?t make the toolholders look like the quality products that they actually are. The reasoning behind thisis that the tool holders can show signs of corrosion after prolonged storing times orin countries with high humidity and temperature. The corrosion doesn?t decrease thetool holders performance, but the customers might believe otherwise.

"Flerspråkigheten kan öppna många dörrar i min framtid" : Hur ryskspråkiga minoritetsungdomar i Estland upplever sin flerspråkighet och dess betydelse för identitet

Issues related to multilingualism and its importance to each individual and the whole society are the subject of today?s school debate. The mere fact that the aspects of multilingualism are discussed actively not only in a school environment but even in the mass media and other communities proves that multilingualism is an important and complex phenomenon in our lives.The subject that I have chosen to study into is about the importance of multilingualism for minority individuals and the conditions for their multilingualism. The aim of this research is to investigate the importance of multilingualism for identity formation among several Russian-speaking young people who were born and raised in Estonia, as well as to try to understand the factors that were relevant to these young people's multilingualism and their view on it. Six young people aged 16-19 were considered in this study.

RUMSSTANDARDISERING : Ett projekteringsunderlag för Sandviks framtida byggnadsprojekt

The construction industry works today with a time limit, therefore it is important to have rational tools to improve the efficiency in the building process. That?s the reason for this report, where a standard for interior finishes has been developed for Sandvik. The standard for interior finishes is designed as a program for room functions and includes office space and sanitary areas. It is a proposal showing how Sandvik can design their premises in the future.

Omvårdnad av nyförlöst kvinna som har infektion av Streptococcus pyogenes : En litteraturstudie

Bakground: Puerperal fever caused by group A Streptococcus is in a global context seen as a common cause of death in childbirth.Aim: To examine the consequences of group A streptococcus infections in women postpartum and to see what a nurse can do to stop the infection with adequate nursing interventions.Method: This is a review built on 15 articles. These articles were read in full and audited with a suitable template.Result: Women postpartum has 20 times higher risk to get group A stretococcus infection as compared to non pregnant. The consequences of Group A Streptococcus infection can lead to high fever, abscesses around the uterus, sepsis, acute respiratory distress syndrome (ARDS), hysterectomy and death. Patients who share room with infected patients carries an increased risk to be infected. Curtains between patient beds can be colonized by Group A Streptococcus.
