The development of future 3D-printed electronics relies on the access to highly conductive inexpensive materials that are printable at low temperatures (<100 C). The implementation of available materials for these applications are, however, still limited by issues related to cost and printing quality. Here, we report on the simple hydrothermal growth of novel nanocomposites that are well suited fo

An overview of carbon dioxide (CO2) exchange and soil respiration measurements is given for representative Hungarian agroecosystems. We present results of long-term atmosphere/biosphere CO2 exchange measurements carried out at the Hungarian tall tower site (Hegyhá tsál). Tall tower net ecosystem exchange (NEE) measurements provided consistent estimates of landscape-wide carbon dioxide dynamics. Du

Background: High-circulating level of parathyroid hormone (PTH) is associated with elevated mortality in dialysis patients. The Japanese Society for Dialysis Therapy guideline suggests a lower PTH target than other international guidelines; thus, PTH control may differ in Japan compared with other regions, and be associated with mortality. Methods: We analyzed data from hemodialysis patients with

Crop harvesting and residue removal from croplands often result in imbalanced biogeochemical cycles of carbon and nutrients in croplands, putting forward an austere challenge to sustainable agricultural production. As a beneficial element, silicon (Si) has multiple eco-physiological functions, which could help crops to acclimatize their unfavorable habitats. Although many studies have reported tha

Symbionts are widespread and might have a substantial effect on the outcome of interactions between species, such as in host-parasitoid systems. Here, we studied the effects of symbionts on the outcome of host-parasitoid interactions in a four-partner system, consisting of the parasitoid wasp Leptopilina boulardi, its two hosts Drosophila melanogaster and D. simulans, the wasp virus LbFV, and the

Airborne dispersal of microorganisms influences their biogeography, gene flow, atmospheric processes, human health and transmission of pathogens that affect humans, plants and animals. The extent of their impact depends essentially on cell-survival rates during the process of aerosolization. A central factor for cell-survival is water availability prior to and upon aerosolization. Also, the abilit

The effect of sub-monolayer silicon on the oxidation of Al(111) and Al(100) surfaces was investigated using X-ray Photoelectron Spectroscopy (XPS) and density functional theory (DFT) calculations. On both surfaces the adatom site is preferred over substituting Si into the Al-lattice; on Al(100) the four fold hollow site is vastly favored wh

In order to significantly improve engine efficiency and reduce exhaust emissions at the same time, new radical combustion concepts have emerged. Gasoline partially premixed combustion (PPC) is one of them, with early results showing high gross indicated efficiency. To achieve that, PPC relies on high EGR (exhaust gas recirculation) use, with numbers that can reach up to 50%. Such a high amount of

Popular Abstract in Swedish Enzymet magnesium-kelatas katalyserar bildandet av magnesuim-protoporfyrin genom insättning av en magnesiumjon i protoporfyrin. Detta är det första unika steget i tillverkningen av klorofyll hos växter, alger och fotosyntetiska bakterier. Magnesium-kelatas är uppbyggt av tre olika proteiner som kallas I (vikt 40 kDa), D (70 kDa) och H (140 kDa). Tillsammans bildar dessaThe insertion of Mg2+ into protoporphyrin IX represents the first committed step in the chlorophyll and bacteriochlorophyll biosynthetic pathways. The reaction is catalyzed by the multisubunit enzyme Mg-chelatase, which consists of three subunits, known as I (molecular weight ~40 kDa), D (~70 kDa), and H (~140 kDa). To fully understand this first step in chlorophyll biosynthesis each protein compo

In this paper a systematic study of the surface influence on the elastic properties of nanosized iron and tungsten wires and films is performed. Single crystal defect-free nanowires and nanofilms are examined through molecular statics simulations, and the concepts of surface energy and third order elastic constants are used in an attempt to describe the elastic properties. For structures where the re

(IB) methods are two popular computational techniques for multi-fluid dynamics. To help shed light on the performance of both techniques, we present accuracy assessment including interfacial geometry, detailed and global transport characteristics. The investigations include the simulations of a droplet under static equilibrium and a droplet rising due to gravity for Re≤1000. Different surface tens

The major uncertainty in predicting the influence of human activities on global climate change is the effect of aerosols. Two physical properties of aerosols largely controlling their influence on climate are the particle number size distribution and the interaction of the particles with the surrounding water vapor. The work presented in this thesis provides new information on the interaction bet

Popular Abstract in Swedish Under de senaste årtiondena har vattenfärgen i många svenska sjöar och vattendrag ökat. Detta innebär att vattnet blir brunare, och detta fenomen benämns därför brunifiering. Brunifiering är inget unikt för Sverige, utan förekommer på åtskilliga ställen på norra halvklotet. Brunifieringen påverkar det akvatiska ekosystemet och vattnets potentiella samhällsnytta. Ur en eThe term brownification refers to the trend of increasing water color, i.e. the water becoming browner, which has been observed throughout the northern hemisphere over the last decades. Brownification has both ecological and societal implications. From an ecological point of view the impaired light climate may e.g. reduce aquatic primary production and affect predator-prey interactions within the

Tick-borne encephalitis virus (TBEV) is a high-impact pathogen with approximately 12,000 diagnoses annually in Eurasia. The virus causes a variety of clinical manifestations, with neurological symptoms in up to 30% of the patients. Lethality in Europe is <2% but post-encephalitis syndrome is seen in over 40% of the infected patients and results in substantial impairment in quality of life. Over th

Popular Abstract in Swedish Det här är en studie av Wallace Stevens poetik och poesi med inriktning på 1930-talet, då hans poesi påverkades av en kraftig kulturell press på socialt engagemang och politisk användbarhet. Argumentet framställer hur olika men samverkande element i hans poetiska språk, som diktion, prosodi och metafor, under den här perioden utnyttjas för att skapa ett intryck av estetThis dissertation studies Wallace Stevens? ideas and practice of poetic language with a focus on the 1930s, an era in which Stevens persistently thematized a keenly felt pressure for the possible social involvement and political utility of poetic language. The argument suggests how mutually implicated elements of his poetry such as diction, prosody and metaphor are relied on to signify or enact ae

In this book, three historical macro-regions are analysed: East Asia, Southeast Asia and Mesoamerica. By comparing three very different historiographical patterns from the specific point of view of social militarisation, we gain an outsider's perspective that proves to be very illuminating. Due to structural features of the various scholarly arenas the three regions turn out very differently. Some

TiO2(B), a potential catalyst support, has been synthesized from a support precursor, K2Ti4O9. High resolution electron microscopy revealed that the 32% volume loss in this transformation is achieved by formation of facetted microvoids, around 10 nm in size, maintaining the morphology and size of the original crystals. A structural mechanism, including a hypothetical structure for a K2Ti 2O5 inter

The objective of this work was to study the formation of DNA-cationic vesicle complexes (lipoplexes). These complexes are interesting not only from a fundamental point of view but also as promising candidates for gene therapy. The approach taken was to study first the cationic vesicles by themselves. This will allow us to better understand the "complexation mechanism" upon the addition of DNA. The
