Popular Abstract in Swedish Optoelektronik genomgår för närvarande en otrolig utveckling, inte minst på grund av de senaste årtiondenas kommersialisering och utveckling av hemelektronik som kompaktdiskar och digitalkameror. Denna utveckling har drivit en blomstrande global tillväxt för optoelektroniska företag som varje år utvidgar sina erbjudanden av optiska komponenter i hård konkurrens. UtvecklThe present thesis describes a number of aspects of modern electro-optical measurement technology also known as bio-photonics; this includes instrumentation, applications, sample interaction and data interpretation. The methods employed operate over several domains, and light measurements are discretized both in intensity, space, angle, time, polarization and energy. Mainly the spectral domain is

To fulfill increasing requirements in the manufacturing sector, companies are faced with several challenges. Three major challenges have been identified regarding time-to-market, vertical feedback loops and level of automation. Grafchart, a graphical language aimed for supervisory control applications, can be used from the process-planning phase, through the implementation phase and all the way to

Research on the use of social network sites by elected politicians has often been narrowed down to behaviour during election campaigns and using social media as a way of reaching voters and journalists. This chapter studies the way that members of parliament in the Swedish Riksdag use social media as a tool for intra-party competition. The analysed data consist of interviews with 37 parliamentaria

The present invention relates to a membrane pump and an apparatus comprising such a membrane pump. The membrane pump comprises a pumping chamber and a flexible member separating the pumping chamber into a first accumulation container and a second accumulation container. The flexible member is configured to be movable within the pumping chamber so as to vary a volume relationship between the first

Popular Abstract in Swedish Det blir allt vanligare att använda sig av medicin som liknar kroppens eget immunförsvar. Eftersom det ställs höga krav på att medicinen måste vara ren när den används så behöver man avskilja farliga substanser. I den här studien tittar vi på sådana reningsprocesser. Antikroppar är en del av det naturliga immunförsvaret hos oss alla. De hjälper till att upptäcka och neuAntibodies are part of the immune system where their purpose is to recognize and neutralize foreign species such as viruses and bacteria, thus preventing and curing infections. The trend of using antibodies in the treatment of, for example, cancer is increasing. These antibodies are produced in bioreactors, but the production stream from the bioreactors also includes impurities such as viruses and

In this paper, we consider the problem of robust optimization for a system with uncertainty of rank one. The main result is the canonical parameterization of all destabilizing uncertainties in the dual problem. The corresponding result in the rational case has been previously stated in terms of unstable zero-pole cancellations.In this paper the result is extended to the class of non-rational syste

This submission is devoted to optimization of networks that permanently experience fluctuations of the capacity available on their links. This is an important and novel topic since limited link availability is a fundamental feature in wireless networks and yet majority of work in survivable network design is restricted to the total single link failures. We assume a given finite set of network stat

Every language has a set of verbs which denote the various actions we perform when we communicate through spoken language. In linguistic literature, these are commonly referred to as speech act verbs and they typically include communicative categories like asking, answering, promising, accusing, telling and a host of others. Most speech act verbs have very specific meanings which limit their usage

This study is part of a larger project that aims at balancing the higher education biased picture of knowledge transfer through international mobility, by emphasising workers on lower educational levels in 20th and 21st century Sweden. The present part study examines the views on experience and knowledge acquired abroad among students at six upper secondary schools connected with Swedish multinati

In order to meet the incremental requirements from clients, fifth generation Wireless Local Area Network(WLAN) protocol IEEE 802.11ac provides a lot more throughput than his predecessors. However, in all distributed channel access 802.11 protocols, probability of packet loss increases with respect to number of available stations; consecutive packet losses in link layer activates congestion control

We report the design of a cyclic, eight-residue peptide that possesses the catalytic triad residues of the serine proteases. A manually built model has been relaxed by 0.3 ns of molecular dynamics simulation at room temperature, during which no major changes occurred in the peptide. The molecule has been synthesised and purified. Two-dimensional NMR spectroscopy provided 35 distance and 7 torsion

A titanium implant in which a conduit is gradually filled with ingrowing bone (the Bone Harvest Chamber) has been modified to allow continuous local treatment of the conduit tissue with biochemical agents. Implants were inserted bilaterally in rabbit tibiae. The tissue content of the bone ingrowth conduits was studied with histology, 99mTc-MDP scintimetry and measurements of total calcium content.

IntroductionThe pulp and paper sector is a key global industry. Presently, pulp mills prioritize the production of pulp, fibers, and electricity. By transforming traditional pulp mills into lignocellulosic biorefineries, they can become a key element of a future, circular bioeconomy. To accomplish this, pulp mills need to close their loops and optimize the use of the lignocellulosic feedstock, not

Understanding the attachment owners can feel to their robot vacuums, which also map and collect data about their homes, is key to understanding the ambivalences involved in the integration of automated visualities in the home. Drawing on qualitative video interviews and observations of people interacting with their robot vacuums, this article identifies three key factors in understanding how cohab

Aquaporins are water channels found in the cell membrane, where they allow the passage of water molecules in and out of the cells. In the kidney collecting duct, arginine vasopressin-dependent trafficking of aquaporin-2 (AQP2) fine-tunes reabsorption of water from pre-urine, allowing precise regulation of the final urine volume. Point mutations in the gene for AQP2 may disturb this process and lea

There is currently considerable interest in producing new materials with extreme combinations of mechanical properties such as high hardnesses and moduli. One example of such a material is crystalline C3N4, which has been predicted to have a bulk modulus higher than that of diamond. In this paper we report on experiments carried out to synthesize CNx thin films. The films were grown in an unbalanc
