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

The second part deals with the possibility to store own-produced electricity from solar panels in a multifamily residential area. The purpose of the first part was to collect information about different energy storage systems in a general study, and examine their di

The relationship between macroeconomic variables and the stock market index has been studied by a large number of academics and practitioners over the last two decades. However,even though the stock market in China has been in rapid development, the similar studies concerning China remain relatively insufficient. This study examines the relationship between the China’s stock market and a set of ma

Today world’s cities are in a state of flux exhibiting complex dynamics and at the core of sustainability challenges including climate change and urbanization. At the same time cities have been acknowledged as agents of change when it comes to addressing these challenges. The urgency to address these problems has triggered cities to find smarter and innovative ways to deal with these challenges. C

Världen, och framförallt Europa, står idag inför stora påfrestningar med en flyktingström vars storlek enbart kan liknas med den under andra världskriget. Denna uppsats syftar till att svara på frågor kring flyktinginvandringens påverkan på den ekonomiska tillväxten på lång sikt. För att besvara frågeställningen görs en teoretisk analys genom att utvidga en tidigare utvidgad modell där effekterna

Denna rapport syftar till att studera regnbäddar och dess funktion vid rening av dagvatten samt vilka olika filter som kan användas. EU:s vattendirektiv från 2000 studeras tillsammas med hur kommuner arbetar med detta idag. En regnbädd definieras som ”en vegetationsbeklädd markbädd med fördröjningszon för infil- trering och behandling av dagvatten” och är en del av en öppen dagvattenhantering, d.v

The pipelined ADC is a popular Nyquist-rate data converter due to its attractive feature of maintaining high accuracy at high conversion rate with low complexity and power consumption. The rapid growth of its application such as mobile system, digital video and high speed data acquisition is driving the pipelined ADC design towards higher speed, higher precision with lower supply voltage and power

This study has investigated the possibilities of coating additive manufactured titanium dental prosthesis structures. Different coating alternatives were evaluated with the regards of esthetics, function and implementation possibilities. The coatings were applied on test samples and the adhesion between the printed titanium structures and the coating as well as to resin veneering applied on top wa

The worlds’ human population is continuously growing, and meeting the increased demand for food requires an increase of agricultural production. Agricultural ecosystems are of great importance for humans in terms of delivering provisioning ecosystem services, such as the production of food. The term ecosystem service is a function provided by natural environments, that are beneficial for humans. A

You might have heard the expression that the eyes are the window to the soul, but what if the eyes are also the window to the brain? What if you could see what happens in a person’s brain only by looking into their eyes? There is indeed a physical link between the eyes and the brain. The retina, the part of the eyes that is responsible for collecting incoming light, develops from a part of the b

The RF power amplifier is one of the most critical blocks of transceivers, as it is expected to provide a suitable output power with high gain, efficiency and linearity. In this paper, a 60-GHz power amplifier based on an injection locked structure is demonstrated in a standard 65 CMOS technology. The PA core consists of a cross-coupled pair of NMOS transistors with an NMOS current source. This st

Bredäng, a housing area in southwest Stockholm, was built between 1963 and 1965 as part of The Million Program, a Swedish government program to fix the housing shortage in the country. Bredäng is characterized by its green and blue qualities, but also by its many parking lots, poor public spaces, monotone architecture and storm water issues. Today, the housing shortage is once again an issue, esp

Beställarens rätt att avbeställa arbeten när denne ingått ett entreprenadavtal med avtalsgrund i AB 04 utreds och analyseras i denna uppsats. Vidare undersöks förhållandet mellan avbeställning och hävning. Detta görs med hjälp av en traditionell rättsdogmatisk metod. Författare på området synes vara överens om att beställaren har en avbeställningsrätt. Men, om denna kan anses följa direkt av AB The buyer´s right to cancellation of works in a commercial construction contract due to AB 04, is analysed in this paper. The relationship between cancellation and termination is also examined. This paper is based on a legal dogmatic method. Authors in this field agrees that the buyer is entitled to cancellation of works. But they do not agree if this right follows directly from AB 04, by outgoi

Understanding the dissolution kinetics is important in the experimental determination of solubility, the efficiency of extractions, the rate of reactions and in general any heterogeneous process. Despite the extensive use of supercritical fluids, studies regarding the dissolution kinetics of compounds in supercritical carbon dioxide (scCO2) using analytical methods are limited in the literature.
