Biosensors, combining a selective biological recognition element and a sensitive transducer, are versatile analytical tools applied more and more in different fields, such as medicine, food quality and safety control, and environment pollution monitoring. They are expected to play an increasingly important role in the improvement of life quality. In this context, the present work covers recent app

In this paper, problems related to simulation model documentation and model exchange between users are discussed. Complex simulation models have gained popularity in the environmental field, but require extensive documentation to allow independent implementation. The existence of different simulation platforms puts high demands on the quality of the original documentation. Recent experiences from
A comparison was made of 15 different techniques which are used in assessing soil microbial populations and/or biomasses. These include direct observations (fungal standing crop, fluorescein diacetate active mycelia, acridine orange stained bacteria), cultural methods (bacterial plate counts), physiological methods (total microbial, bacterial and fungal biomasses, O2-uptake), soil enzyme analyses
Popular Abstract in Swedish Arbetet i denna avhandling syftar till att utveckla bättre ljuskällor för fluorescensavbildning och fotodynamisk behandling av cancertumörer. Små kompakta diodlasrar är ideala ljuskällor för detta, men en del kliniska användningar kräver att deras prestanda förbättras. Gemensamt för de bägge diagnostik- och behandlingsmetoderna är att man behöver uppnå högre strålkvalitThis work concerns techniques for improvement of the coherence properties of diode lasers so that they may be used in two specific medical applications: (Interstitial) photodynamic therapy (PDT) and laser-induced fluorescence diagnostics. In the first application, spatial coherence is crucial, since the treatment light should be delivered through relatively thin optical fibers to optimize treatmen
Popular Abstract in Swedish Sedan årtionden ökar antalet frakturer över hela världen, och i alla ålderskategorier. Frakturer leder ofta till längre tids funktionsinskränkning, sämre livskvalitet och ibland till döden. Projektet ?Malmö Förebyggande Medicin?, an populationsbaserad, prospektiv studie av 22 444 män, medelålder 44 år, och 10 902 kvinnor, medelålder 50 år, är väl lämpad för studier av vThe number of fractures is increasing worldwide, and fractures frequently cause long-term disability, impaired quality of life and sometimes death. The Malmö Preventive Project, a population-based, prospective study, consisting of 22 444 men, mean age 44 and 10 902 women, mean age 50 years, provides data for evaluation of common public health conditions, such as fracture and diabetes. The follow-u
We have implemented a non-null type checker for Java and a new non-null inferencing algorithm for analyzing legacy code. The tools are modular extensions to the JastAdd extensible Java compiler, illustrating how pluggable type systems can be achieved. The resulting implementation is compact, less than 230 lines of code for the non-null checker and 460 for the inferencer. Non-null checking is a loc
This article summarizes the status of the ATLAS detector and its commissioning as of autumn 2006, one year before the expected LHC start-up. The initial running scenarios and goals for B physics are presented for the foreseen pilot run with 900 GeV centre-of-mass energy in autumn 2007, as well as for the first physics run in 2008 at the nominal centre-of-mass energy of 14 TeV.
To achieve software product quality professional skill and knowledge is important. The way to reach software product quality is often structured approaches for software quality such as SPI and CMM which have been criticized for lack of a knowledge perspective. The view taken in this study is that software product quality is related to interpretations and understanding in practice, and thus on prac
This article presents a research agenda about waste management from the perspective of management and organization studies. The agenda suggests that scholars should draw upon research on waste governance, lean management, the circular economy, and sustainable consumption. It also suggests, in a crossdisciplinary spirit, that scholars should heed research on waste within other social sciences and t
Popular Abstract in Swedish Under de senaste årtiondena har både kraftsensorer och digitala kameror kommit att bli vanliga som sensorer i olika robotiktillämpningar. Denna avhandling behandlar olika problem inom visuell rörelseskattning och återkoppling, samt integrationen av dessa tekniker med reglering av kontaktkrafter för en industrirobot. Olika ämnen tas upp, från grundläggande teori till praOver the last decades, both force sensors and cameras have emerged as useful sensors for different applications in robotics. This thesis considers a number of dynamic visual tracking and control problems, as well as the integration of these techniques with contact force control. Different topics ranging from basic theory to system implementation and applications are treated. A new interface develo
We show that Calogero-Sutherland models for interacting particles have a natural supersymmetric extension. For the construction, we use Jacobians that appear in certain superspaces. Some of the resulting Hamiltonians have a direct interpretation as models for two kinds of interacting particles. One model may serve to describe interacting electrons in a lower and upper band of a one-dimensional sem
Test scheduling and Test Access Mechanism (TAM)design are two important tasks in the development of a System-on-Chip (SOC)test solution.Previous test scheduling techniques assume a dedicated designed TAM which have the advantage of high exibility in the scheduling process. However,hardware verhead for implementing the TAM and additional routing is required of the TAMs.In this paper we propose a te
In marked contrast with the ideal error-free feedback assumption that is common in the literature, practical systems are likely to have severely bandwidth-limited, error-prone feedback channels. We consider the scenario where feedback from the receiver is used by the transmitter to select the best antenna, out of many available antennas, for data transmission. Feedback errors cause the transmitter
Using the configuration interaction technique, the energy spectra of 2s(2)2p(4), 2s2p(5), 2s(2)2p(3)3s, 2s(2)2p(3)3d, configurations of oxygen-like chlorine Cl X have been calculated. The obtained data are used for the evaluation of wavelengths and oscillator strengths of all possible one-electron and two-electron 2s(2)2P(3)3p-2s2p(5) electric dipole transitions. The calculated results are compare
Non-linear waves have been a research topic for a long time, but have not yet entered common ocean engineering practice. In this article the problem of calculating the probability density function (pdf) for non-linear waves is investigated. The 'saddle point approximation' is applied to a second-order wave model to estimate the pdf. The performance of the approximation is compared with the perform
In the present review we summarize different strategies to induce DNA compaction and decompaction. DNA compaction is achieved using different cationic co-solutes, such as trivalent ions, surfactant, and polycations. In addition, single-chained DNA compaction can also be achieved in solvents with low dielectric constants and by confinement. The decompaction strategies depend, naturally, on the meth
Vision (both using one-dimensional and two-dimensional retina) is useful for the autonomous navigation of vehicles. In this paper the case of a vehicle equipped with multiple cameras with non-overlapping views is considered. The geometry and algebra of such a moving platform of cameras are considered. In particular we formulate and solve structure and motion problems for a few novel cases of such
