The present master thesis concerns the standard of protection of companies’ rights in Europe within the field of EU Competition Law. The main question asked is whether the EU competition law enforcement proceedings are in compliance with the standard of protection of companies’ rights set by the Strasbourg Court, or shall there be more safeguards provided for the companies in the EU in order to ma
Along with a deeper integrated world economy have countries discovered the benefits of harmonizing and simplifying the procedures linked to international trade, referred to as trade faciliation. A quite unexplored part of this field of research is yet how trade facilitation affects international investment flows, referred to as Foreign Direct Investments (FDI). In theory is trade facilitation affe
Staden Frutal, centrerad i den brasilianska delstaten Minas Gerais är idag under stark urbanisering och utveckling. Målet med denna studie var att ta reda på om den starka urbaniseringen har påverkat närliggande vattensystem och dess vattenkvalité. I studien har vattenkvalitén i floden Frutal, en flod liggandes centralt i staden Frutal, jämförts med vattenkvalitén i floden Bebedouro, en lantlig flThis study highlights the key issues that urban river systems face due to urbanization.

The aim of this study was to compare two rivers in this area, the Frutal River, an urban located river, with the Bebedouro River, which is a rural river approximately 3 km
I denna kvalitativa intervjuundersökning har jobbcoaching för arbetslösa studerats. Platsen för undersökningen är en kommunal verksamhet med det fiktiva namnet JobbForum. Organisationen har praktiserat arbetsmarknadscoaching som metod sedan 2011. Undersökningen äger alltså rum i en stabil organisatorisk kontext, till skillnad från övrig forskning på jobbcoaching i Sverige. Studien vill fånga hur d
The baobab is among the commonly consumed wild fruits found in the semi-arid regions of sub-Saharan Africa. It has a wide application in food systems and folk medicine and has an advantage of surviving even in harsh environmental conditions. While the fruit pulp is packed with a lot of essential nutrients and has gained much interest in recent past on the international market as a healthy ‘superfo
Ständiga förbättringar är viktiga för att upprätthålla ett företags konkurrenskraft inom sin bransch. Kunderna vill ha en hög leveranssäkerhet och flexibilitet för sina ordrar, men utförande från tillverkningsföretagens sida riskerar att vara bristande. Därför kan utförandet av kartläggningar och mätningar av orderprocessen, i kombination med förbättringar, stärka ett företags vidare konkurrenskraContinuous improvement is important for maintaining a company’s competitive position in its own industry. Customers want a high delivery reliability and flexibility for their orders, but the performance of the manufacturers is likely to be deficient. Therefore, the execution of mapping and measurements of the order process, combined with improvements, enhance corporate competitiveness further. An
The natural elements are used as a driving force for positive urban life in Akureyri, Iceland with the snow accumulation as a leader to unite the town in a physical and social way. The elements of snow buildup in the urban environment are used to find ways to give the town added value in the form of recreational opportunities and commuting routes. Additionally using a system of snow storage to min
This study aims to examine how the sensitivity for macroeconomic announcements surprises changes for the exchange rate in terms of a crisis. Previous research has been biased for U.S announcements and their relation towards emerging market, which has shown that U.S announcements affect more than the domestic. It also suggests that business cycle and uncertainty affect and increase the reaction for
The purpose of this study has been to investigate the experience of being a child challenging the food culture one was born into by going vegetarian. Five grown up informants who made a conscious and deliberate choice to abstain from meat during childhood have had the opportunity to tell their stories through a semi-structured interview. The interviews were analyzed thematically by means of Interp
Business Rules är regler som definierar en del av en affärsverksamhet. I stora IT-system är det viktigt att snabbt kunna hitta den regel som skall appliceras, en uppgift som blir allt mer tidskrävande när antalet regler ökar.Business Rules Engines are systems created to deliver relevant business information to applications and business processes. Given that rule engines are meant to be heavily queried, efficient rule search is essential. However, since the advent of Big Data, it has become increasingly difficult to maintain the rule engine performance - more data often leads to more rules. In this thesis we prototype
Förbättringar i reproducerbarhet och kapacitet av akustiska mikrofluidiska infångningssystem Vad är akustisk infångning? Arbetet i den här uppsatsen är fokuserat på mikrofluidiska system som med hjälp av ultraljud kan fånga in celler och små partiklar. Mikrofluidik är ett fält som innefattar tekniker där man hanterar små flöden i mycket små kanaler. Principen för akustisk infångning bygger på attAcoustic trapping is a novel technology that allows for microfluidic sample preparation and pretreatment. The aim of this text is to give the reader a general insight in microfluidics with a focus on acoustic trapping. One of the next steps in the development of acoustic trapping is to promote commercialization of the technology which requires that similar devices can be manufactured reproducibly.
De första mikrosekunderna efter Big Bang (den stora smällen) tros det ha bildats något som kallas kvark-gluonplasma. Kvark-gluonplasma består av kvarkar och gluoner, som är så kallade elementärpartiklar. Elementärpartiklar är de minsta kända beståndsdelarna. Kvarkarna bygger upp större partiklar som kallas hadroner, exempel på hadroner är protonen och neutronen som atomkärnan består av. Det som håIn high-energy heavy-ion collisions, a state of matter called quark-gluon plasma (QGP) can be created. The production of particles from the QGP can be described by different models, one of these is the blast-wave model. The blast-wave model describes the production of particles from the QGP, not from jets. The model was fitted to the existing transverse momentum spectra (pT) for pions, kaons and p
The turbo code used in the 3GPP Long Term Evolution(LTE) standard have been chosen specifically to simplify parallel turbo decoding and thus achieving higher throughputs. The higher data rates however leads to an increased computational complexity and thus a higher power and energy consumption of the decoder. This report presents a turbo decoder for the LTE standard with a stopping crite- ria aime
One of the most pressing present day health concern is the constantly growing increase of diabetes and the metabolic syndrome. In fact the WHO estimates that as much as 300 million individuals could suffer from diabetes by 2025. While genetic factors do contribute to these issues the more common cause is modern day environmental factors like diets rich in fat or highly processed food, low levels oCan meal order influence blood glucose and insulin levels? When carbohydrates like white bread, rice etc. are consumed, glucose levels in the blood start to rise.Depending on how fast this rise in blood glucose levels occurs carbohydrates can be divided into high GI and low GI foods. High GI foods like bread, potatoes etc. cause a rapid spike in blood glucose levels while low GI foods like pasta c
