Cyanobacteria in fresh water can cause serious threats to drinking water supplies. Managing cyanobacterial blooms particularly at small drinking water treatment plants is challenging. Because large amount of cyanobacteria may cause clogging in the treatment process and various cyanotoxins are hard to remove, while they may cause severe health problems. There is lack of instructions of what cyanoba
This study suggests an optimization framework to plan and design a network of bike lanes in an urban context, based on equity principles and subject to a given available budget. The novelty of the proposal consists in an objective function that aims at minimizing the existing inequities among different population groups in terms of accessibility/opportunity to the bikeways. The proposed methodolog
Wetlands are one of the most significant natural sources of methane (CH4) to the atmosphere. They emit CH4 because decomposition of soil organic matter in waterlogged anoxic conditions produces CH4, in addition to carbon dioxide (CO2). Production of CH4 and how much of it escapes to the atmosphere depend on a multitude of environmental drivers. Models simulating the processes leading to CH4 emissi
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
Massive parallel sequencing (MPS) is increasingly used for human identification purposes in forensic DNA laboratories. Forensic DNA samples are by nature heterogeneous and of varying quality, both concerning DNA integrity and matrices, creating a need for assays that can handle low amounts of DNA as well as impurities. Commercial short tandem repeat (STR) analysis kits for capillary electrophoresi
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
This paper presents achievable uplink (UL) sum-rate predictions for a measured line-of-sight (LOS) massive multiple-input, multiple-output (MIMO) (MMIMO) scenario and illustrates the trade-off between spatial multiplexing performance and channel de-coherence rate for an increasing number of base station (BS) antennas. In addition, an orthogonal frequency division multiplexing (OFDM) case study is
Lifetime measurements are presented for the ls2p3P1, 2 levels for He-like C V and N VI. From the measured lifetimes, transition probabilities are deduced for both allowed and spin-forbidden transitions. The values for the 1s23S0-1s2p3P1 transition rates, 0.29 × 108 and 1.38 × 108 s-1 for C V and N VI respectively, are found to be in good agreement with theory.
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.
Purpose – The purpose of this paper is to demonstrate that, important as reflexivity is, it does not constitute the gold standard of qualitative research. Instead the author makes a plea for the use of sociological imagination. Design/methodology/approach – The paper makes use of data from the ISI Web of Science database to demonstrate the increasing popularity of the concept of reflexivity. Findi
Hybridization is increasingly recognized as a potent evolutionary force. Although additive genetic variation and novel combinations of parental genes theoretically increase the potential for hybrid species to adapt, few empirical studies have investigated the adaptive potential within a hybrid species. Here, we address whether genomic contingencies, adaptation to climate, or diet best explain dive
We have developed an aquatic inelastic hyperspectral lidar with unrestricted focal-depth and enough sensitivity and spatio-temporal resolution to detect and resolve position and behavior of individual sub-millimeter aquatic organisms. We demonstrate ranging with monitoring of elastic echoes, water Raman signals and fluorescence from chlorophyllbearing phytoplankton and dye tagged organisms. The sy
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
The polymerase chain reaction (PCR) is the backbone of contemporary DNA/RNA analysis, ideally enabling detection of one or just a few target molecules. However, when analysing food or forensic samples the analytical procedure is often challenged by low amounts of poor quality template molecules and complex matrices. Applying optimised and validated methods in all steps of the analysis workflow, i.
During the last few years, a more liberal use of premedication in children scheduled for Ürinary tract examinations was noted. In this retrospective study, the influence of the institution of psychological means for preparation as supplement or alternative to premedication on the incidence of cases receiving premedication was investigated. During the period from 1978 to 1982, this was followed in
The main goal with this thesis is to develop a method to maximize the fuel efficiency [ton/l] in construction machines, while fulfilling the desired productivity [ton/h]. This is achieved by focusing on two of the main influencers; the machine concept evaluation and the development of operator assist systems. To be able to perform a concept evaluation that is unbiased from control engineering expe
