This study analyzed direct and indirect relationships in water consumption by Macedonian economic sectors using virtual water in an input–output framework. Macedonia was found to be characterized by intensive water consumption, with some sectors having a significant virtual water content in their products. Virtual water multipliers were used to analyze the trade balance and determine whethernation
Streptococcal pharyngitis is among the most common bacterial infections, but the molecular mechanisms involved remain poorly understood. Here we investigate the interactions among three major players in streptococcal pharyngitis: streptococci, plasma, and saliva. We find that saliva activates the plasma coagulation system through both the extrinsic and the intrinsic pathways, entrapping the bacter
We discuss finite volume effects and partial quenching for Chiral Perturbation Theory in the mesonic sector. The effects are computed in terms of analytical expressions for masses, decay constants and vacuum expectation values (VEVs) to two-loop order. Numerical examples are presented for a number of interesting and relevant cases. All numerical programs are publically available, the prospects of
To test the hypothesis that dissolved organic nitrogen (DON) is important for sustaining primary production by the microphytobenthos (MPB) in nitrogen-limited conditions, we measured the uptake of (15)N-labelled urea, the amino acids glycine (GLY) and glutamic acid (GLU), and nitrate and ammonium under simulated in situ light and temperature conditions. Microphytobenthic primary production and chl
We consider the effect of signaling rate (baud rate) on the information rate of single carrier linear transmission systems with Gaussian inputs. Several different communication scenarios are investigated: correlated or uncorrelated symbols, a fixed modulation pulse or a modulation pulse varying with the signaling rate and frequency selective or flat channels. For uncorrelated symbols, we show that
This study is based on a total cohort (N = 192) of people born in 1902 and 1903 and living in southern Sweden. Subjects were assessed at baseline when 67 years of age and on eight further occasions over 34 years or until death. The participation rate in the nine examinations ranged from 78-100%. Interviews, psychological tests, and medical examinations were used as well as information on medical d
The aim of this work is to generate detailed and simplified kinetic models for the oxidation of the Primary Reference Fuels (PRF) n-heptane, iso-octane and their mixtures, with low numbers of species and reactions. These mechanisms are consistent in terms of the choice of kinetic parameters for the different reaction classes. The further aim is to validate the kinetic models for a wide range of di
Inhemsk mikroalg skapar hållbarhet genom kombination av produktion och vattenrening Genom att använda snabbväxande mikroalger i avloppsvatten för produktion av biomassa har vattnet renats och det enda som tillsätts är solljus och koldioxid. Denna metod möjliggör hållbar produktion av en rad produkter, däribland biobränslen, samtidigt som samhällstjänster såsom vatten- och luftrening utförs på köpAbstract A few local microalgae was isolated and cultivated in vertical column with artificial lighting in 12 h light cycles in wastewater at the local wastewater treatment plant. The growth of the algae strains was observed and the fastest growing (Scenedesmus sp.) was subsequently cultivated outdoors under natural sunlight. pH controlled CO2 input resulted in up to twice as high biomass product
Radiation protection is of importance for the general public, patients and personnel in many different situations: rare accidents involving ionizing radiation, medical examinations or work tasks in the medical clinic or nuclear industry to name a few. Optimization in radiation protection and limitation of radiation doses are essential to prevent overexposure and for reducing negative health conseq
Despite available vaccines, rotavirus (RV) gastroenteritis remains to be an alarming cause of under-five mortality, especially in developing countries. Research on RV has been limited by the lack of faithful in vitro models that mimic virus-host interaction and RV pathogenesis in the intestine. Most recently, adult stem cell-derived organoids have advanced the understanding of the cellular mechani
The purpose of this study is an understanding of operator work in a production line and its connection and translation into simulation. A mapping of operator work in the production line was performed, after which tasks and were analysed for their relevance for simulation. A model draft was developed in the software FlexSim. The mapping and the derived model provides insight into operator work in t
The Intermediate Data Structure (IDS) is a standardised database structure for longitudinal historical databases. Such a common structure facilitates data sharing and comparative research. In this study, we propose an extended version of IDS, named IDS-Geo, that also includes geographic data. The geographic data that will be stored in IDS-Geo are primarily buildings and/or property units, and the
Context. Positions and proper motions of Gaia sources are expressed in a reference frame that ideally should be non-rotating relative to distant extragalactic objects, coincident with the International Celestial Reference System (ICRS), and consistent across all magnitudes. For sources fainter than 16th magnitude, this is achieved through Gaia's direct observations of quasars. At brighter magnitud
SynopsisVarious protolytic species of thiols RSH (thioglycolic acid, l-cysteine, dl-penicillamine, and glutathione) in rapid equilibria with each other reduce trans-[Pt(CN)4Cl2]2- in parallel, halide-bridged electron transfer reactions. A linear Brønsted correlation between the reactivity of the thiolate anions RS- and their basicity is observed. The mechanism derived might be used as a model for
Syftet med denna avhandling är att undersöka diffusionen av den fjärde industriella revolutionen inom livsmedelsindustrin i södra Sverige. Intresset för begreppet Industri 4.0 har ökat stadigt sedan det infördes av den tyska regeringen 2011. Men diffusionen verkar låg. Om Industri 4.0 är en revolution är införandet av den nya tekniken avgörande för konkurrenskraften. Detta faktum har resulterat i The aim with this thesis is to investigate the diffusion of the fourth industrial revolution in the food manufacturing industry in southern Sweden (FMISS). The interest of the concept Industry 4.0 has increased steadily since the introduction by the German government in 2011. However, the diffusion seems slow. If Industry 4.0 is a revolution, adoption of the new technologies will be crucial for co
Nanoteknik är ‘big business’. Stora summor pengar står på spel då detta innovativa teknikområde expanderar i snabb takt. Denna undersökning utgår från antagandet att ekonomiska intressen snarare än demokratiska värden och hållbar utveckling styr utvecklingen av nanoteknik i Sverige idag. Detta ses som problematiskt, och det övergripande målet är att föreslå alternativa principer för att styra utveNanotechnology is big business. With rapid innovation and expansion of the field, financial stakes are high. This study is based on the assumption that the development of nanotechnology in Sweden today is controlled by economic interests rather than democratic values and sustainable development. This is considered problematic, and the overall aim with this study is to propose alternative principle

Background: Heterogeneity of prostate cancer (PCa) contributes to inaccurate cancer screening and diagnosis, unnecessary biopsies, and overtreatment. We intended to develop non-invasive urine tests for accurate PCa diagnosis to avoid unnecessary biopsies. Methods: Using a machine learning program, we identified a 25-Gene Panel classifier for distinguishing PCa and benign prostate. A non-invasive t
