Avgång av lustgas från luftningsprocessen på Käppalaverket
The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.
Lindex - vägen till en tydligare logotyp
Lindex has a strong fashion position and is one of northern Europe's leading fashion retailers. Unfortunately their logotype no longer measures up to the fashion level that is required. Surveys and interviews have been conducted with employees at Lindex, disscusing their logotype. I have come to the conclusion that what is needed from Lindex side is strict guidlines for the employees to follow so that all information from Lindex to their customers is made with a great touch of fashion to it and in a coherent way..
Arboga möter miljöutmaningar och klimatförändringar
Municipalities in Sweden are responsible for physical planning by developing a general plan. This plan contains intended land and water use for the area. This study aims to investigate the level of integration of environmental issues in the general plan of Arboga municipality and also how well adapted the municipality is for climate change. Further on, the study intends to examine the focus of the general plan and at what rate the national environmental strategies are implemented in the local physical planning of Arboga municipality. Methods used for this study are interviews and reviewing of the general plan itself and other key documents.
UTVÄRDERING AV HÖFTLEDSARTROSKOPI FÖR PATIENTER MED FEMUROACETABULÄRT INKLÄMNINGSSYNDROM : Samband mellan självskattning och fysisk prestationsförmåga
Bakgrund: Sjuksköterskor som arbetar på akutmottagningar möter dagligen patienter som är alkohol- eller narkotikapåverkade. När patienter kommer till akutmottagningen och är påverkade av alkohol eller narkotika förekommer det ofta våld. Det vårdvetenskapliga perspektivet i examensarbetet är Kaséns syn på vårdrelationen och delaktighet. Syfte: Syftet är att beskriva sjuksköterskors erfarenheter av att möta patienter som är påverkade av alkohol eller narkotika på akutmottagning. Metod: Sex narrativa intervjuer har genomförts med sjuksköterskor som arbetar på en akutmottagning i mellersta Sverige.
Evaluation of creditability and risk minimisation : The effect of accounting for intangibles
The recent history knows numerous examples of creditor?s inability to evaluate financial solvency of the client correctly. Creditors? risks do not only concern individual relations between the two parties but the economy in general. The standard loan-giving procedure considers evaluation based on a number of financial ratios.
Miljöcertifiering av hotellverksamheter : varför miljöcertifiera?
The awareness regarding environmental issues is increasing and as a result a large number of products are eco-labeled. This enables the consumers to make enlightened environmental decisions when purchasing products. Eco-labeling is no longer for products only, but also for services like hotels. It?s difficult to determine what it actually means to eco-label a hotel and what kind of benefits it includes.
Framtiden för gamla Habo ullspinneri
This report presents an investigation and a new design of Habo Ullspinneris old industrial premises. It is based on the owners visions and wishes, two questionnaires and also considering of the historical value.Habo Ullspinneri was founded in 1882 by Frans August Johansson and was moved to the location it has today, near Hökån in Habo, three years later. The electricity that the machines in the industry needed was extracted from the small river that is placed under the building. In 1960 there was a fire and the result became the end of the industrial activity that had taken place in the building.There is no steady activity in the building at the moment. It is nowadays temporarily used as an agriculture museum and as a store room.
Energikartläggning hos RostiGP i Gislaved
In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.
Effekter av högt kaliumintag på magnesiumbalansen hos mjölkkor :
Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms.
The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.
Visuellt typinstrument : en metrologisk studie
Visual Type Instrument - VTI, is a tool containing a typeface and a set of geometric calculations that generates numerical data in spreadsheets. The data is determined from the typefaces visual dimensions and is used to calculate leading, type size, margins and format. The aim is to offer, for all of those working with typography and design, a practical way to manage text, image and format in relationship to visual size. Instead of using point measurements, VTI uses a new device called Edo. An Edo is the same as one twelfth of a millimetre.
Revisorers internationella mobilitet
Syftet med den här uppsatsen var att undersöka vad som påverkar revisorns val att arbeta eller inte arbeta internationellt och i vilken mån detta påverkar honom.Eftersom vi inte fann någon passande teori beslöt vi oss för att skapa vår egen. Denna teori utgår från egna antaganden och andras teorier och har byggts upp med hjälp av fem hypoteser, vilka vi rangordnat efter hur mycket vi antar att de påverkar revisorns val. De fem hypoteserna är: legala, stabilitet, sociala, kulturella och ekonomiska. Då vi ville gör arbetet mer intressant valde vi att undersöka tre länder: Sverige, Storbritannien och Kroatien, detta medförde att vi kunde göra jämförelser mellan revisorer från dessa länder.För att det skulle vara möjligt för oss att uppfylla syftet och för att kunna testa om vår teori var korrekt samlade vi in primärdata och sekundärdata. Primärdatan består av svaren vi fick på våra e-postenkäter medan sekundärdatan innehåller information om revisorsutbildningarna samt information om Sverige, Storbritannien och Kroatien.Utifrån analyser på dessa data drog vi slutsatsen att vår teori inte var korrekt fullt ut då hypoteserna legala och stabilitet ej påverkade revisorns val att arbeta eller inte arbeta internationellt i den utsträckning som vi antog.
Development of Liquid Cooling for PCs
In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.
Beror KRAV-grisars ledanmärkningar på miljöfaktorer?
This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.
Kvinnor som är entreprenörer Bestämningsfaktorer och regional variation
The proportion of women entrepreneurs in Sweden is, as in many countries, smaller than the proportion of men entrepreneurs. Sweden has therefore created political measures with the ambition to increase women entrepreneurship. However, knowledge about the determinants of women entrepreneurship is needed in order to enable the promotion of it and, at the same time one can question the treatment of women entrepreneurs as a homogenous group. The purpose of this thesis is to investigate the determinants of women entrepreneurship and whether these determinants fluctuate regionally. If this proves to be the case, a more spatial/individual approach should be used, when creating measures to promote entrepreneurship.
Numerisk modell för global transport av spårämnen i atmosfären
The aim of this project was to develop a numerical model simulating the global transport of air pollution. The model currently used by SMHI, the Swedish Meteorological and Hydrological Institute, was intended to perform such simulations at regional scales. However, the usage of a grid based on longitudes and latitudes makes this model work poorly in global simulations. The problem with this grid is that the nodes are concentrated near the North and South Poles. Due to this characteristic, the Courant, Friedrich and Lewy-condition for numerical stability puts a sharp bound on the timestep length.
