Power electronics result in increased harmonic distortion, but can also be used for harmonic mitigation. This requires simple, low order models for nonlinear networks. The Harmonic Norton Equivalent is a load model structure that supports aggregation of nonlinear loads, and makes nonlinear network solving (i.e. simulation) a non-iterative procedure. It is a linearized description of the relation b
Recently, mass spectrometry (MS) has emerged as an important tool for high-throughput screening (HTS) providing a direct and label-free detection method, complementing traditional fluorescent and colorimetric methodologies. Among the various MS techniques used for HTS, matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) provides many of the characteristics required for high-th
Increasing use of the ground as a thermal reservoir is expected in the near future. Shallow geothermal energy (SGE) systems have proved to be sustainable alternative solutions for buildings and infrastructure conditioning in many areas across the globe in the past decades. Recently novel solutions, including energy geostructures, where SGE systems are coupled with foundation heat exchangers, have
ObjectivesThe main objective of this study was to derive cost estimates of five major foodborne illnesses (campylobacteriosis, salmonellosis, enterohemorrhagic Escherichia coli (EHEC), yersiniosis and shigellosis) in Sweden. These estimates provide a necessary contribution to perform future cost-benefit analyses aimed at reducing the burden of foodborne disease. A secondary aim was to obtain estim
An analytical method is presented, combining novel microcontact imprinting technique and capacitive biosensor technology for the detection of BSA. Glass cover slips were used for preparation of protein stamps. The microcontact-BSA imprinted gold electrodes were prepared in the presence of methacrylic acid (MAA) and poly-ethylene glycol dimethacrylate (PEGDMA) as the cross-linker by bringing the pr
I vår kropp finns en myriad av proteiner och celler med viktiga funktioner och de flesta av dem är täckta av kolhydrater. Galektiner är en familj proteiner som har en ficka där olika kolhydrater kan binda in. Genom att kolhydrater på celler eller andra proteiner binder in till denna ficka kan galektiner påverka cellulära funktioner. Vid cancer och inflammation har överproduktion av vissa galektineGalectins are a class of β-galactoside-binding proteins that bind glycoconjugates and have been implicated in cancer, regulation of immunity and inflammation. Design and synthesis have achieved highly potent and selective galectin ligands that can inhibit interactions with glycoproteins and have consequent cellular effects. These ligands can be used as tools to further elucidate the roles of galec
The total resources form copper, zinc and lead was estimated from a reworking of the literature. The data was used as input to the integrated systems dynamics model BRONZE, and used to estimate the global supply of these metals and the by-products antimony, indium, germanium, tellurium, cadmium, bismuth and selenium. The runs show that copper, zinc and lead go through peak production around 2050 a
This paper compares the signal-to-noise ratio obtained using an InSb photodiode for infrared (IR) polarization spectroscopy to that obtained using an upconversion detector, and shows a factor 64 improvement by the change. Upconversion detection is based on using sum frequency generation to move the IR optical signal to near-visible wavelengths to improve the sensitivity.
Semiconductor nanowire solar cells have achieved comparable efficiency to their planar counterparts with substantial reduction of material consumption. Tandem geometry is a path towards even higher efficiency. However, extensive studies are needed to reach this goal. My study started from the building blocks of the materials used in the upper cell, namely GaInP nanowires. The growth and doping con
Digital PCR techniques are ideally suited for accurately quantifying trace amounts of target DNA sequences, such as tumor-derived mutant DNA that is present in the blood circulation of patients with cancer. Here, we describe an approach marrying low-coverage whole-genome sequencing of tumor tissues, to enumerate chromosomal rearrangement breakpoints, together with droplet digital PCR (ddPCR)-based
R&D related foreign direct investments represent a powerful mechanism for cross-border knowledge sharing that can stimulate the process of technological catch-up. However, low-income countries and smaller middle-income countries remain largely excluded from this kind of global flows of knowledge. In this chapter, we discuss the motivations and implications of this type of FDI for low and middl
Rice, as one of the most important crops in the world, is facing an ever-accelerating challenge from climate change. Epigenetic modification with its substantially high epimutation rate and the possibility for some epigenetic variation to act as a heritable contributor to crop environmental adaptability may hold great potentials for rapid crop breeding. Epigenetic modification is controlled by epi
#104_loga, a nonlinear scale of time, for tpt, tbn. “loga, a nonlinear scale of time” refers to the illusion of nonlinear time perception. This idea suggests that our estimation of time intervals whether on a small (milliseconds) or large (decades) scale should be logarithmic, giving us a subjective experience very different from clock or calendar. Of course, our perception of time is influenced b
#100. ASEAN Voices, for erhu and 10 mixed ASEAN ensemble players (2017). Premiere: Premiered by C asean Consonant (an ASEAN traditional ensemble), during the 2017 China-ASEAN Music Week at the Guangxi University of the Arts on May 27, 2017. The conductor was Knote KnocKnote with erhu soloist Hu Liu.
Living in a complex and dynamically changing environment requires accurate and timely behavioural responses that allow for adapting to such changes. Well-developed perceptual systems provide a continuous flow of abundant and up-to-date information on the changes in the environment, and, thereby, allow for tailoring behavioural responses accordingly. However, issuing any behavioral response would n
