The aim of this thesis was to compare different ways of dissociating tissue - specifically breast cancer tissue - and sorting out tumour cells and immune cells from the dissociated tissue using acoustophoresis in a microfluidic chip. Due to ethical issues with using tumour tissues to work on the methodology of a project, ultimately only healthy breast tissue was used in this work. Two dissociatio
The urge for more sustainable and environmental-friendly transportation has never been as high as it is today. The demand will probably continue to increase as the knowledge about climate change continues to widen and as the expectations, of mitigation and adaptation measures, intensifies. One sector that is in great need of taking more mitigation and adaptation measures is the transport sector. T
Problem definition Nowadays society is very concerned with sustainability. Companies try their best to meet sustainability customers’ expectations and regulations. The adoption of Lean and Six Sigma could bring sustainability improvements, but it is not clear how these three areas are combined and how they are currently addressed by companies. Purpose Explore the relationship between Lean, Six Sig
Sustainable waste management is a complex task within environmental governance, and municipalities play a key role in governing a transition of the waste system toward prevention and reuse. This calls for an enhanced understanding of local capacities for change, and therefore this thesis adopts a socio-institutional perspective on the power of actors to influence local transitions. Through a quali
Den biologiska mångfalden fortsätter att minska trots att det såväl nationellt som internationellt finns en målsättning om att förlusten av den biologiska mångfalden ska hejdas. Idag anses en av de största miljöpolitiska utmaningarna vara att stoppa utarmningen av biologisk mångfald. Skogen utgör livsmiljö för hälften av alla landlevande arter i Sverige och ett hållbart skogsbruk är således livsavBiodiversity is in decline despite international and national goals of preventing this development. Preserving biodiversity is one of today’s greatest environmental policy challenges. Currently, half of all land living species in Sweden live in the forest, therefore a sustainable forestry industry is vital to ensure biodiversity. In fact, half of all red-listed species live in the forest. One of t
MAX IV is a synchrotron facility currently running 14 beamlines hosting about 1000 users per year. It is one of the best of its kind; producing high quality Xrays at the forefront of synchrotron science. To have a beamline or a synchrotron functional, every equipment used needs to be placed in the workspace with high precision. In the current setup, this is supported by bluelining, a technique to
Corporate Social Responsibility (CSR) har under det senaste decenniet blivit ett allt mer relevant koncept. De flesta multinationella företag (Multinational Enterprises, MNEs) har formulerat uppförandekoder och många har också anslutit sig till internationella initiativ som fokuserar på CSR, som exempelvis Förenta Nationernas Global Compact. Genom globalisering, avreglering, paradigmskiften och inCorporate Social Responsibility (CSR) has during the last decade become an increasingly relevant concept. Most Multinational Enterprises (MNEs) have formulated Corporate Codes of Conduct, and many have also joined international initiatives focusing on CSR, such as the United Nations Global Compact. Through globalisation, deregulation, paradigm shifts and not least the development of information te
Solar power clearly has one of the greatest potential among renewable energy but a big setback is that it is still relatively expensive. Engineering of materials on a nanoscale, e.g. the growth of nanowires makes it possible to make semiconductor-materials with better optical properties while using less material than for traditional bulk semiconductors. This means that nanowire based solar cells h
In 1994 the Swedish Construction Code, BKR, was changed from being based on material to being based on function. This permitted constructing multi-storey buildings with a bearing framework made of wood, which had been prohibited since the end of the 19th century. There is now a growing in- terest of using wood as a construction material. In Växjö four seven-storey buildings, Limnologen, are under
Mögel som växer inomhus har påvisats orsaka ohälsa som andningsbesvär, allergi och eksem. Eftersom vi tillbringar större delen av våra liv i inomhusmiljöer är det viktigt att hitta lösningar på detta problem. Eftersom det finns mögelsporer i luften och går det inte att undvika att få in dem i våra byggnader. Det som går att göra är att förhindra sporerna från att gro. Syftet med detta projekt har Mould growing indoors has been shown to cause health problems such as respiratory disorders, allergies and eczema. Since we spend most of our lives in indoor environments, it is important to find solutions to this problem. As mould spores are present in the air one cannot avoid getting them into buildings, but it is possible to prevent the spores from germinating. The purpose of this project was t
Saturated laser-induced fluorescence (saturated LIF) has been the topic of some research, however mainly regarding laser diagnostic methods conducted on flames. A few papers have discussed saturated LIF with the purpose of producing saturation curves of different fluorescent elements. The utilised methods in these cases have involved manually increasing the laser intensity and detecting the fluore
This study aims to contribute with knowledge regarding how street-level bureaucrats within the police and the social services in Malmö experience their discretion and conditions for information exchange for crime prevention purposes among children. The study also aims to examine what standards for working methods, and the discussion between privacy protection and law enforcement, that can be ident
Objective Second language learning continues to be a field of growing interest both in academia and everyday life. As such, a more comprehensive understanding of the best learning methods remains an important area of focus. This study aimed to investigate single-session vocabulary acquisition and neural underpinnings of language learning through Diffusion Tensor Imaging (DTI), in relation to immer
N,N-diphenyl carbazolium salt has attracted interest for applications in anionic exchange membranes (AEM) due to its structural features and the high chemical stability that the compound exhibit. AEM are polymeric membranes with positively charged functional groups. They can be employed as electrolytes in alkaline fuel cells. In this project, different types of N,N-diphenyl carbazolium compounds w
Retrieval orientations refer to cognitive states that, if adopted, tonically orients episodic retrieval attempts towards the sought-after type of information. Such orientations can enhance episodic retrieval by modulating the processing and effectiveness of retrieval cues. The current study investigated if retrieval orientations are adopted volitionally and spontaneously, as previous studies have
This work is an investigation into practical design and loss minimization of DC/DC-switched power supplies, enabling cooler operation, smaller size, and additional or wider areas of use. There is an abundance of switch controller ICs on the market and a few of the manufacturers offer very sophisticated design tools that suggest operating parameters and grade components. However, one of the major
In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. The dynamic range is maximized by using passive topologies for both the a
This report describes a part of the product development process for a mechanical adjustment of the head pressure in an extruder at Tetra Pak. The pressure is adjusted by a valve that increases or decreases the pressure by moving a valve stem. In the current solution the valve stem is moved by hand, which will no longer be effective when Tetra Pak streamlines the extruder. The project also includes
Informationssamhällets framväxt bidrar med nya utmaningar för rättsliga regleringar utformade efter traditionella gränser när dessa ska upprätthållas i en gränslös digital miljö. Digitaliseringen av samhället ger upphov till rättsfrågor som inte nödvändigtvis är nya men som placerar dessa i en ny miljö, vilket bidrar till en viss osäkerhet kring rättsläget i många fall. Mot bakgrund av detta behanThe development of the information society brings new challenges to legal constructions created in a landscape of traditional boundaries when these are to be upheld and enforced in a borderless digital environment, mainly due to a technical development that is constantly pushing the boundaries. An increased digitalisation of the society gives rise to not necessarily new legal questions but put the
Measurement of prostate-specific antigen (PSA) in blood is an important tool in detection for prostate cancer. PSA occurs in several molecular forms in blood: mainly as a free form with a molecular mass of 28 kDa; and as PSA complexed to alpha-1-antichymotrypsin, complexed PSA, with a molecular mass of 90 kDa. Total PSA comprises the sum of free PSA and complexed PSA. The percentage of free-to-tot
