Macaneta spit is located about 30km north of Maputo, Mozambique, with the Indian Ocean on the east side and Incomáti River on the west side of the spit, composing an interesting and vulnerable area from a hydrodynamic point of view. Few studies regarding coastal processes are done in the area and changes of the morphology could result in breaching of the spit and thereby affect both accessibility
När betongplattrambroar modelleras med moderna linjära 3D FE-modeller kommer stora dragkrafter att uppstå i brons tvärriktning från temperatur- och krympningslasterna. Dessa tvångskrafter är då mycket större än vad som har beaktats i de äldre 2D modellerna. Detta leder till att den tvärgående armeringsmängden, som beräknas i 3D-modellerna, är mycket större än vad som har varit norm innan. Denna avWhen concrete slab frame bridges are designed with modern linear 3D FE-models large tensile restraint forces will arise in the transversal direction of the bridge from the temperature and shrinkage loads. These restraint forces are much larger than those that are accounted for in the older 2D models. This leads to that the amount of transversal reinforcement, calculated in the 3D FE-calculations,
Popular science summary Complex I, let me see your true color Every day of our lives our body performs many different tasks to let us survive, such as brain activity, muscle contractions or smaller tasks like cell- repair or -division. All those tasks require energy. The energy currency of our body is called ATP (adenosintriphosphate), a molecule that lets us perform many reactions in our body.
With the diminishing reserves of oil and the growing public concern for environmental issues, the end of gasoline powered vehicles is getting closer each year. To prevent this from causing the personal and comfortable way of transportation mankind has gotten used to, to die with them, an alternative without the downsides of the gasoline engine must be developed. The environmentally friendly electr
A combination of acoustic trapping and impedance spectroscopy for micrometer-sized objects is here presented for the first time. Acoustic trapping has proven to be a well-functioning method for non-contact immobilization and positioning of particles or cells in microfluidic channels. The combination with impedance spectroscopy allows for simultaneous electrical measurements on the trapped objects.
Prosodic cues such as stress and tones can help listeners predict upcoming structures and get a first crack at rapidly unfolding speech. The prosodic feature stød in Danish can distinguish word meanings but also signal imminent structures. For instance, monosyllabic nouns with stød lose stød when followed by the plural indefinite suffix -e. Suffixes invalidly cued by stød or non-stød have been fou
Ultraljud och mikrochip kan hjälpa oss att förstå cancer bättre En tumör och dess omgivning spelar stor roll i hur cancer utvecklas och genom att förstå vilka celler den består av och sortera ut de viktigaste kan man öka kunskapen om hur cancern bäst ska bekämpas. I detta arbete har immunceller från sådan upplöst bröstvävnad sorteras ut med hjälp av ett mikrochip med små kanaler samt en ultraljudThe 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
Production and patient safety requirements are high in pharmaceutical industries where standards are set accordingly and controlled by e.g. the U.S. Food and Drug Administration (FDA). It is crucial that these standards are met without compromising the fact that production must run as effectively as possible, i.e. achieve Overall Equipment Efficiency (OEE), for the pharmaceutical companies to deli
Databehandling av signaler från millimetervågsradar i realtid Radarsensorer som använder millimetervågor är väldigt användbara inom avkänningsteknik, som har tillämpningar inom bland annat sjukvården, autonoma robotar, osv. Detta examensarbete bygger vidare på en genomförbarhetsstudie som med positiva resultat undersökte om det var möjligt att med hjälp av elektronik och algoritmer förhindra fallBased on the feasibility study [4], the goal of this master thesis is to compile custom firmware for the XM112 Pulsed Coherent Radar Module, which features a state of the art radar sensor integrated with a microcontroller unit (MCU). This allows the use of custom firmware to check the plausibility of real-time data processing on the radar signals and will lay some of the groundwork for further dev
The aim of this study is to understand how individuals construct their workplace at home, while they work from home digitally during the corona pandemic. The method through which the study has been conducted in order to achieve its aim is qualitative interviews. These were constructed to be held in the digital format of a digital communication software. The same format in which all e-workers have
The European building sector is a source of significant negative environmental impacts, and large part of its carbon emissions can be attributed to heating, cooling and lighting of buildings – in other words, regulating buildings’ indoor environments. As people spend most of their lives indoors, there is a great challenge to create comfortable indoor environments, while also striving for further e
Radar - Dina ögon i nacken när du cyklar Cyklister är en utsatt grupp av trafikanter för olyckor. För att öka säkerheten kan radarteknologi användas för övervakning av döda vinkeln samt ge mervärde till fordonet. Med en enkel notis så kommer man undvika risken med att inte veta vad som kommer bakifrån.The purpose of this thesis is to develop a blind spot detection system for increased safety and comfort for a biker. The solution is based on power-efficient small A111 radars, developed by Acconeer AB, which have a range up to seven meters while consuming only a few milliwatts. Sensor evaluation is performed for the intended use and from this, concepts are generated. These are tested to obtain t
During the last few years, the interest for electric vehicles has increased enormously, there are even talk of prohibiting fossil fuels in the coming years. There is a risk that the charging of these electric vehicles can strain the electric grid. The simulations of the grid with added power demand from the electric vehicles concludes that there will not be a problem on the low- and medium voltage
Intresset för att bygga fler och högre trähus i Sverige har senaste tiden ökat bland annat då trä är ett betydligt mer miljövänligt alternativ att bygga med än stål och betong. Stomsystem i trä har dock ingen naturlig sammanhållning likt en platsgjuten betongstomme och därför måste anslutningarna i en trästomme hanteras explicit. RISE (Research Institutes of Sweden) driver en konceptstudie om högaThe interest in building more and higher timber buildings in Sweden has recently increased, for example, because wood is a much more environmentally friendly alternative to construct with then steel and concrete. Frame system in wood has no natural cohesion like a cast concrete frame and therefore the connection in a wooden frame must be managed explicitly. RISE (Research Institutes of Sweden) run
Det råder idag en trend att förtäta, det vill säga bygga tätt i städer istället för att låta städer växa utåt. Det finns många fördelar med att förtäta då en tät stad ger underlag för bättre service och tätare kollektivtrafik vilket därmed kan leda till mer hållbara städer. Men det finns också nackdelar med att bygga tätt. Genom att förtäta städer samlas fler människor på mindre ytor och därmed ocToday it has become a trend to densify cities instead of allowing them to grow outwards. Densification has many advantages, a dense city provides a basis for better service and denser public transport, which can lead to more sustainable cities. However, building dense also has its disadvantages. By densifying cities, more people gather on a smaller area. This result in more children on a smaller a
The aim of this master’s thesis is to examine the preservation of audiovisual objects and how methods surrounding this may affect the material as well as the archival profession. Physical recording formats – such as cassette tapes or compact discs – deteriorate quickly and are becoming progressively obsolete, which in turn makes it problematic to safeguard the information they contain. It is there
Unfired clay is an ancient building material that has been used for centuries, as a result a third of the human population lives in earth houses today. Earth as a building material was neglected during the industrial revolution in Sweden, which means that well developed standards and regulations for earthen material do not exist today. The lack of standards and regulations can cause problems and f
This thesis explores how disaster-affected communities in the Kavre and Bardiya districts of Nepal perceive and experience cash assistance projects. The research was guided by two core questions: (1) What are community members' perceptions and preferences of cash assistance in disaster affected areas in the Kavre and Bardiya districts of Nepal? (2) How could these community perceptions and pre
With the definite dialectic relationship between the fashion industry and models, this bachelor’s thesis seeks to research the usage of models’ body types in relation to two different fashion companies. These two companies consist of Très Bien and Zalando, which occupy different spaces of the larger fashion landscape, with Très Bien being a smaller and more alternative fashion company and Zalando
Background and aim: Ischemia-reperfusion (I/R) in the intestines activates leukocytes and reactive oxygen species (ROS) and leads to lipid peroxidation and DNA damage. Rosehips have a high content of polyphenols and might prevent lipid peroxidation. Some Lactobacillus species are capable of degrading polyphenols to simpler and non-toxic constituents, sometimes with enhanced antioxidative capacity.
