Synoptisk provtagning i vattendrag med eutrofieringsproblem : En studie för att identifiera områden för prioritering av åtgärder

In Halland, agriculture is the major source of eutrophication of water. In the study, synoptic sampling were performed in the three watercourses Nyrebäcken, Skintan and Vinån all located in the county of Halland. Sampling occurred during the period February to May on three occasions with different flow rates: high, low and base flow. Samples were taken in the mainstream and tributaries with intention to show how big the impact of eutrophication it is in the water and  to assess the impact of the tributariesThe results show that all watercourses are affected by eutrophication. Nyrebäcken has the highest concentrations of nitrogen and phosphorus in the mainstream, then Skintan and last Vinån.

Rapportera Mera?: En kvalitativ studie av hur svenska finanschefer uppfattar kravet på kvartalsrapportering

The purpose of this paper is to study how Swedish CFOs perceive that the requirement for companies to issue quarterly reports affect business operations in the company. The fact that it is regulations on the Stockholm Stock Exchange, and not the law, that requires companies to issue quarterly reports makes Sweden unique in Europe. The paper is based on interviews with CFOs from 32 companies quoted on the Stockholm Stock Exchange. The major finding in the study is that a majority of the CFOs perceive that the pressure for short term results, created by quarterly reports, affect their work and the investment decisions made in the company. Also CFOs feel that the market over interprets the information given in quarterly reports.

Drömmen om att segra över marknaden : En jämförelsestudie mellan aktierekommendationer och insidertransaktioner som portföljstrategi

The purpose of this paper is to compare two different portfolio strategies consisting of insider transactions and stock recommendations and examine whether they posses any information advantage.  The portfolios are balanced once every three-, six- and twelve- months in the period of 2007-2009. Our results show a pattern for these investment strategies. The portfolio consisting of insider transactions generates a positive return in equity in a negative market environment and the opposite reaction in a positive environment. The result for the portfolio consisting of stock recommendations show a positive return of equity in positive environment and the opposite effect in negative environment. The pattern that has been observed can be classified as an anomaly.

Val av teknik för hastighetsmätning i kallvalsverk

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

FRISTADS ? Supply Chains, från tråd till arbetsbyxa

The Swedish Textile industry has since the beginning of the 70-ties moved their production to countries with cheap labour further and further away. The production in the Baltic countries and Asia has become reality for many Swedish manufacturing companies. With today?s technology the communication with remote countries has ceased to be a problem. The difficulties have instead turned out to be more focused on transportation of goods and just in time deliveries to Sweden.

Att kommunicera skapar incitament till att investera : En studie om investor relations påverkan på aktiekursen

Purpose: To examine how IR-related press releases affect share price for stock companies, and to explore how said companies practice Investor Relations.Methods: The study was conducted using an event study as well as e-interviews. The event study has a quantitative deductive research approach where the market model is used for calculating the abnormal return based on press releases. The e-interviews have a qualitative research approach and follow a semi structured interview guide. The study includes all listed stock companies within the Swedish construction industry and includes press releases from the last decade.Theory: The study is based on the efficient market hypothesis and its semi strong form, theories within Investor Relations and previous research.Results: The event study shows a significant negative abnormal return during a four day period starting the day after the press release event. The negative abnormal return could derive from investor relations being used by companies as damage control, or that the investors? expectations are too high as a result of IR.

Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

Noble Operations: En studie av Stadshuskällarens processflöden

The aim of this thesis is to study Stadshuskällaren?s operational processe flow and identify their operational characteristics. The uniqueness of Stadshuskällaren is that they are breaking the law of trade-offs regarding volume/variety, much like Toyota managed to do ? which spawned the entire field of research of the ?Lean Philosophy?. In the thesis the characteristics we identify through analysis, which enables Stadshuskällaren to break the trade-off, are compared with the principles of Lean service theory, which ultimately stem from Toyota.

Modeling Determinants of First-Day Returns from IPOs

The primary purpose of this paper is to find the determinants of first-day returns on the Stockholm Stock Exchange. Our research will cover the 1996 ? 2004 periods. Our secondary purpose is intended to find a profitable trading strategy with regard to future IPOs on the Stockholm Stock Exchange. By using regression analysis, focusing on company specific factors and the IPO process, we hope to find a function exhibiting statistical significance, determining future first-day returns from which construction of a profitable trading strategy will be possible.

Finns det ett samband mellan börsnoterade företags resultat och dess värdering?

Background: What is a share and what determines the value of a company? This is a constant issue that many in the financial world are facing. Many argue that there has been some decoupling between stock valuation and how the company in question is developing operationally after the financial crisis that the world faced during 2008-2009.Problem: It is important to distinguish between the company and the share. A company that is good and well maintained may not be worth buying only because of it. The share is judged by other elements also.

Grammatiken bakom den politiska retoriken : En syntaxstudie av före detta statssekreterare Lars Danielssons uttalanden angående sitt ansvar i regeringens hantering av tsunamikatastrofen 2004

In this thesis I based on Fowler?s method of syntax analysis construct a flow scheme which I then use to make a syntax analysis of former State Secretary Lars Danielsson?s statements, in his autobiography, regarding his responsibility in the Swedish government?s management of the 2004 Indian Ocean tsunami disaster. The focus of the flow scheme is how grammatical constructions can be used in the interest of rhetoric?s to on the syntax (non-explicit) level of the text indicate and place responsibility with or outside of involved individuals. The main conclusion of the syntax analysis performed is that Danielsson in his autobiography in fact does not use very many of the constructions described in the flow scheme, whereby it can be concluded that the syntax analysis in this case wasn?t so ?revealing?.

Abnorm avkastning utifrån Benjamin Grahams värdestrategi : Ett ex ante test för de svenska, amerikanska samt japansk aktiemarknaderna

Theability to beat the market is one of the most discussed topics in finance. Thereare very few investors that manage to accomplish this over longer periods oftime. Most of the financial research claims that this is impossible unless theinvestor increase the risk in the portfolio. However numerous of researchershave shown that it exist anomalies on the stock market which either indicatesthat the Capital Asset Pricing Modell (CAPM) or Fama and French three-factormodel fails to explain stock returns or that the market is not fully efficient.One investor that has claimed that the stock market is not fully efficient andthat it is possible to generate abnormal return is Benjamin Graham. Graham isone of the legends on Wall Street and he has shown that by using few variablesbased on public information, one can manage to beat the market over longer timeperiods.There arejust a few studies that have tested Graham?s criteria?s, however all of themindicates that they work but that the standard deviation might be higher forthe portfolios.

Evaluation of a Flow Cytometry Method for Identifying and Quantifying Fetal Red Blood Cells in Maternal Blood

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

Headhunting : Rätt "man" på rätt plats?

Syftet med denna studie var att undersöka unga idrottares upplevelser i en topprestation.Studiens frågeställningar var:·        Vilka upplevelser har unga idrottare i en topprestation?·        Upplever unga idrottare flow i en topprestation?·        Vilka faktorer ligger bakom en topprestation hos unga idrottare? Utifrån syfte och frågeställningar valdes mätinstrumentet Flow State Scale-2 (FSS-2). FSS-2 består av ett påståendeformulär som mäter den totala upplevelsen av flow samt var och en av de nio dimensionerna av flow.Kontakt togs via telefon och mail med ansvariga tränare vid idrottsgymnasier för att finna unga idrottare med ett tydligt minne av en topprestation. Undersökningsgruppen blev 51 stycken unga idrottare, män och kvinnor i åldrarna16-20 år som utövat fotboll, ishockey eller orientering på elitnivå.Litteratursökning gjordes i bibliotekskatalogen tillhörande Umeå Universitet. Den funna relevanta litteraturen och artiklarna har legat till grund för denna studies bakgrundsdel. Påståendeformuläret FSS-2 visar att undersökningspersonerna, i sin topprestation, hade en stark upplevelse av inre tillfredsställelse, tydliga mål, koncentration på uppgiften, känsla av kontroll och balans mellan skicklighet och utmaning.
