We test a new approach to calculate the mean velocity and velocity dispersion for a sample of nearby stars when their radial velocities are not available. The most commonly used method (here called the projection method, PM) was introduced in a paper by Dehnen & Binney (1998). That method is here compared, theoretically and numerically, with an application of the Maximum Likelihood (ML) method

Uppsatsen syfte är att undersöka huruvida en minskning av working capital kan påverka lönsamheten och om det i så fall skulle kunna användas som en strategi för företagsledningar. Ett sekundärt syfte är att undersöka om finanskrisen har påverkat arbetet med att minska working capital. Uppsatsen exemplifierar problemet genom att undersöka en hårt konkurrensutsatt bransch, hemelektronikbranschen i SThis study examine the relationship between working capital and profitability to see if a reduction of working capital could be used as a strategy for managers to increase profitability. A second purpose of this paper is to examine how the latest global financial crisis can impact working capital management. This paper exemplifies this problem by examining a struggling industry in Sweden, specific

Syftet med studien är att identifiera och förklara hur aktiekurser vid nyemissioner, när turbulensen ökar, fluktuerar på Stockholmsbörsen och vilka faktorer som påverkar aktiekursutvecklingen. Detta sker genom att undersöka hur olika faktorer kan bidra till att förklara variationen i kursrörelserna vid nyemissioner på kort sikt. Resultatet ämnar hjälpa befintliga och potentiella aktieägare samt öv

Abstract Almost nothing is known about the Tibetan wolf (Canis lupus chanco) apart from opportunistic anecdotes, notes in journals and conflict with humans. Taxonomic status of this canine has not been investigated so far for Nepal's wild population to state it as Tibetan wolf or Himalayan wolf. Furthermore, persecution of the wolf has been a major issue in the Himalayan region without any det

Abstract Parkinson’s disease (PD) is characterized by selective loss of dopaminergic neurons and progressive accumulation of intracellular alpha synuclein protein aggregates known as Lewy bodies. Due to pathological links to both sporadic and inherited cases of PD, alpha synuclein (asyn) has become a focal point for study, although the exact mechanisms of its toxicity are not known. In contrast to

Cellular signalling and potential agents to combat prostate cancer Prostate cancer (PCa) arises as a result of uncontrolled proliferation of the cells in the male prostate gland. The male androgenic hormone, testosterone fuels prostate cancer cells. In the cells of the prostate, the androgen receptor (AR) acts as the signal receiver and effector of androgen, ultimately leading to the growth and s

ABSTRACT The genetic characteristics of two soft tissue tumors were investigated in the present study: pleomorphic hyalinizing angiectatic tumor (PHAT) and solitary fibrous tumor (SFT). PHAT is a benign soft tissue tumor of uncertain cellular origin and lineage of differentiation. Although PHAT is still poorly characterized at the genetic level, one reported case has shown a potential genetic ove

Syftet med studien var att undersöka om det föreligger ett samband mellan anställningsotrygghet och mental ohälsa och somatisk stress. Ett annat mål var att testa om kontroll och socialt stöd är kopplade till anställningsotrygghet. Matrialet samlades in genom en surveyundersökning som mätte anställningsotrygghet, mental hälsa, somatisk stress, socialt stöd och kontroll. I studien deltog 46 anställ

ABSTRACT Ribonucleotide reductase (RNR) catalyzes the rate‐limiting step of dNTP production. The availability of finely tuned dNTP pools is very important to maintain genome stability during DNA synthesis for replication and repair. Therefore the activity of RNR is tightly regulated via various mechanisms. In yeast species RNR inhibitors proteins prevent the RNR activation in the G1 and G2 phases

Earlier studies in other countries have found that inequity and social economic factors influence crime. We examine if the same influence could be found in Sweden. Through a multiple regression we analyze material from Sweden’s 290 municipalities. The dependent variable is measured through reported acts of violent crime since this reflects the total crime rate better than other possible measuremen

Sammanfattning: Ett informationssystem är i grund och botten ett sätt att lagra och bearbeta information. Alla sådana system bygger på en informationsmodell, det vill säga en modell för hur data organiseras för att de ska gå att bearbeta och omvandla till information. Idag existerar avancerade informationssystem för att göra spatiala analyser (GIS) och för att hantera byggnader (BLM-system). För nSummary: An information system is basically a way to store and process information. All such systems are built from an information model, in essence a model for how to organize data in order to make it possible to process, thus turning it into information. Today there exist advanced information systems for performing spatial analysis (GIS) and to model buildings (BLM-systems). At present the devel

The purpose of this project has been to illuminate whether employees within big scaled production kitchens have the necessary, appropriate and vital education regarding how to handle food and eatables and to discuss the consequences that may arise as a direct result of insufficient knowledge on the subject of temperature and food. This study was carried out with the support and supervision of mil

Det har länge förts en debatt om huruvida medelarskyddet för privatanställda bör utökas. Flera utredningar har gjorts på området, men ingen har lett till mer omfattande lagstiftningsåtgärder. I juni år 2012 beslutades att frågan om stärkt meddelarskydd för privatanställda ska ses över igen, nu avseende offentligt finansierad verksamhet och framförallt sådan verksamhet som avser vård, skola och omsFor long there has been an ongoing debate about whether or not employees working in the private sector should have the right to publish information about their workplace. Several commissions have taken form regarding this issue, but none of them have led to legislation. In June 2012 it was decided that a new commission shall investigate this matter, this time regarding sectors financed by public f

This thesis is focusing on the protection of fundamental human rights at work for third country migrant workers in the European Union, a region which attracts more and more migrant workers in recent years. The first Chapter introduces the background briefly, the methodology and the sources on which the research is conducted on and provides the scope and definition of the issues which are under dis

Persuasive Technology, technology that is designed to change users’ attitudes or behaviors, has been exercised for a long time. Designing a technology that can change users’ attitudes or behaviors is a process that needs to be carefully thought through. Captology makes this process easier by defining the most important factors that technology needs to contain in order to be classified as Persuasiv

The Potential of Esters as Renewable Fuels: Determination of Laminar Burning Velocities Biodiesel fuel is widely used as a clean fuel in car engines. Ester fuels are a one kind of a biodiesel fuel which includes many chemical compounds. Due to their chemical and physical properties these esters are difficult to investigate in a laboratory. The heat flux method was used in this study to determine
