Alléers användning genom tiderna i Sverige : en bakgrund till alléns framtida utveckling
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
BIM - Förvaltarens Framtid
For nearly twenty years people have been talking about Product models, but given that the building industry is so conservative, it is hard to implement new working methods. Product models are these days known as Building Information Modeling, BIM. People often say they work with BIM but they often forget the most important part, the information. A 3D model should be linked with characteristics and information. Information that can be invaluable for the facility manager.We have a vision that in the best of worlds the facility manager would be able to "walk" into the model and see what kind of installations are inside the wall or in the roof.
Dynamiska egenskaper hos håldäcksbjälklag belastade med gångtrafik
Concrete floors have traditionally had no problems with annoying vibrations. However with the demand for larger spans the floors need to be made more slender with a higher degree of utilization and lower mass. Therefore new floors may have problems with vibration serviceability. This thesis studies the vibration characteristics of hollow core slabs. The analysis was made in the finite element program Ansys. The hollow core slab was subjected to a varying force simulating one person walking across the slab.
Varför kan man tvätta med tvättnötter (Sapindus mukorossi)? : en litteraturstudie om de aktiva ämnena i tvättnötter och hur de fungerar vid tvätt av kläder
Soapnuts have been used as a cleaning detergent and medicine since ancient times in different parts of Asia. Today soapnuts are sold as an environmentally friendly alternative to common washing detergents. The aim of this literary study is to give an answer to what it is in the soapnuts that makes them work as a washing detergent. The active component belongs to a group of components called saponins which are secondary metabolites with the purpose to protect the tree from pathogen attacks. Saponins are widely spread in the vegetable kingdom and some of the families and species are so rich in saponins that their names are influenced by this, for example Sapnindaceae and Sapindus which are mentioned in the beginning of this literary study.
Ledningsarbetet hos ett krisföretag : en analys av ledningens hantering av en ekonomisk kris
Almost every company sooner or later ends up in a more or less difficult economical situation. The reason for the economical crisis varies for each individual case but common for them all is that it is the management group that has failed in their work to guide the organisation to avoid a negative result. The next common denominator is that it is the management group that has to handle the changes in the company's environment and lead the company out of the crisis. But how can they do this and take decisions in a rational and effective way and is there warnings signals that the management group missed before the crisis was a fact? This is
some of the questions that this study is going to discuss and analyze.
The aim of the study is from a management perspective chart the strategic work of the company's management work when handling an economical crisis.
?r omfattande varum?rkesr?ttigheter nyckeln till innovation? En utredning av risker vid individanpassning av kl?der p? den europeiska marknaden
This thesis examines the legal boundaries of third-party use of trademarks in the European customized clothing market. The purpose is to determine under what circumstances third parties may legally modify and sell trademarked apparel without infringing on trademark rights. The study employs a legal dogmatic method, analyzing EU trademark law, case law, and legal doctrine to clarify the scope of exclusive rights and their limitations. By analyzing key EU case law, the study further illustrates how the legal framework has been interpreted and applied in cases concerning third-party trademark use.
Given the increasing demand for customized fashion and the rise of new business models in the clothing industry, this topic holds significant legal and economic relevance.
Additionally, Schumpeter?s theory of creative destruction provides a theoretical perspective on how trademark restrictions impact innovation and market competition.
Undersökning av ackommodationsförmåga och brytningsfel hos varmblodiga travare :
Skiascopy is used to objectively determine the refractive power of the eye. Except for a Swedish study in 2007, where 93 horses of different breeds and ages were examined with respect to their refractive status, most studies on equine refraction were published about one century ago or more. The objective of this study is to examine the refractive status of healthy warm-blooded trotting horses.
Skiascopy was performed in 117 horses in total, aged 3 days to approximately 22 years old. In a pilot study, it was determined whether young horses were able to accommodate or not during skiascopy. The horses in the pilot study were all younger than 14 months.
In foals younger than 1,5 months we saw a significant difference in the skiascopy result in the right eyes before and after topical atropine was instilled, but not in the left eye.
Fem-studie av rörelser i planet mellan bakaxelbrygga ADA1100 och centralväxelhuslock R780
This thesis has been performed at Scania CV AB Technical Centre in Södertälje and its aim hasbeen to study the causes and effects of deformations in the interface between the rear axlehousing ADA1100 and the central gear house R780 during operation. Design changes that wouldincrease the sealing capability of the studied interface are also suggested. Finite element (FE)and CAD software have been the primary tools in this study.Finite element (FE) simulations are used in the industry to predict and develop engineeringdesigns. The main motive for FE simulations has traditionally been to identify weak spots in thedesign, regarding high tensions and large deformations.The FE model is an aggregation of submodels and interface models that represents the rear axlehousing, suspension, central gear, central gear housing, wheels, bolts and weldings, and theirinteractions. The submodels have different material properties and they are connected withcontact interface models.Boundary conditions are defined on the bushings in front of the rear axle and on the air bellowsbehind the rear axle.
Hållbara uppvärmningsalternativ för Grinda Wärdshus : En studie om uppvärmning med pellets och flis
This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating system. The aim of this thesis is to investigate whether wood chips or pellets is, from a sustainability standpoint, a suitable heating method for the guest house.
Elförbrukningen i svenska hushåll : En analys inom projektet ?Förbättrad energistatistik i bebyggelsen? för Energimyndigheten
Energimyndigheten har drivit ett projekt kallat ?Förbättrad energistatistik i bebyggelsen? för att få mer kunskap om energianvändningen i byggnader. Denna rapport fokuserar på ?Mätning av hushållsel på apparatnivå? som var ett delprojekt.Diverse regressionsmodeller används i denna rapport för att undersöka sambandet mellan elanvändningen och de olika förklarande variablerna, som exempelvis hushållens bakgrundsvariabler, hushållstyp och geografiska läge, elförbrukningen av olika elapparater samt antalet elapparater.Datamaterialet innefattar 389 hushåll där de flesta är spridda runt om i Mälardalen. Ett fåtal mätningar gjordes på hushåll i Kiruna och Malmö.Slutsatsen vi kan dra från denna uppsats är att hushållens bakgrund, hustyp, geografiska läge och antal elapparater samt dessa apparaters typ har relevans för elförbrukningen i ett hushåll..
Val av outsourcing-leverantör. En fallbaserad studie av hur organisationer väljer outsourcing leverantör.
This report explores how organizations act when they are choosing an Outsourcing supplier. The study was conducted through multiple interviews with managers of different organizations. The data from those interviews was then analyzed through the use of two theoretical models. Our findings indicate that most organizations share the same base factors (qualifiers) when selecting an Outsourcing supplier. What therefore become crucial are the key factors that the Organizations see as Order winning factors.
Prediktering av komponenters mognad/kvalitet utifrån felkodsutfall
This master thesis has been carried out at Scania R&D at the department of Powertrain Control System Development during the winter 2011/2012. The purpose of the thesis was to produce a method that with the result of troubles codes from the field testing would be able to say something about the maturation of a component, in this case the VGT, variable geometry turbocharger. To start with, it was necessary to investigate hich information was available. After the information been summed up in tables and charts, this so that it was possible to understand the huge amount of data, the calculations started.Since the thesis was about maturation of a component the proportions were calculated of components that had a trouble code in contrast of those who passed the test without a trouble code. This Thesis includes background information about basic of statistics and about the company Scania and its testing process.
Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

DEHP - från mjukgörare till hormonstörande
Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.
