A mycorrhizal fungus grows on biochar and captures phosphorus from its surfaces

Biochar application to soils has potential to simultaneously improve soil fertility and store carbon to aid climate change mitigation. While many studies have shown positive effects on plant yields, much less is known about the synergies between biochar and plant growth promoting microbes, such as mycorrhizal fungi. We present the first evidence that arbuscular mycorrhizal (AM) fungi can use bioch

Emerging aspects of nanotoxicology in health and disease: From agriculture and food sector to cancer therapeutics.

Nanotechnology is an evolving scientific field that has allowed the manufacturing of materials with novel physicochemical and biological properties, offering a wide spectrum of potential applications. Properties of nanoparticles that contribute to their usefulness include their markedly increased surface area in relation to mass, surface reactivity and insolubility, ability to agglomerate or chang

Myndighetssamverkan i barnahus - organisering, innehåll och process. Delrapport 4 i utvärderingen av nationell försöksverksamhet med barnahus 2006-2007

I ett barnahus ska myndigheter samverka under ett tak vid utredningar av misstänkta brott mot barn. Samverkan ska bidra till kontinuerligt utbyte av kunskap och information i såväl enskilda ärenden som på en övergripande nivå. Men vad händer när olika professionella såsom socionomer, poliser, åklagare, rättsmedicinare och psykologer ska samverka? Hur påverkas deras arbete? Vilka svårigheter och vi

Lighting Energy Saving with Light Pipe in Farm Animal Production

The Swedish animal production sector has potential for saving electric lighting of €4-9 million per year using efficient daylight utilisation. To demonstrate this, two light pipe systems, Velux® (house 1) and Solatube® (house 2), are installed in two identical pig houses to determine if the required light intensity, daylight autonomy (DA), and reduced electricity use for illumination can be achiev

Linking the input to the output: new sets of neurons complement the polarization vision network in the locust central complex.

Polarized light is a key feature of the blue sky, used by many animals as a sensory cue for compass navigation. Like other insects, locusts perceive the E-vector orientation of polarized light with a specialized region of their compound eye, the dorsal rim area. Neurons in the brain relay this information through several processing stages to the central complex. The central complex has a modular n

Biomass burning in eastern Europe during spring 2006 caused high deposition of ammonium in northern Fennoscandia

High air concentrations of ammonium were detected at low and high altitude sites in Sweden, Finland and Norway during the spring 2006, coinciding with polluted air from biomass burning in eastern Europe passing over central and northern Fennoscandia. Unusually high values for throughfall deposition of ammonium were detected at one low altitude site and several high altitude sites in north Sweden.

Self-Service BI does it Change the Rule of the Game for BI Systems Designers

Users of Business Intelligence (BI) systems have started to demand more flexible systems in which they could be empowered to serve themselves – self-service BI. In this paper we aim at explaining how such development influences designers of BI solutions and how it impacts the design situation. To say something about this we adapted the PACT (People, Activity, Context, Technology) framework on the

Wagons at Work: A Transport Revolution from Below – the Case of Sweden, 1750-1850

The introduction of turnpike trusts has been considered to be an integral part of the rapid decline in transport costs in England. Institutional change in the transport system or the lack thereof has been used to explain if and when a transport revolution occurred in different localities. However, improved roads are just one component of declining inland transport costs. In this paper, we specific

Barnskötarna, förskollärarna och det förtydligade pedagogiska uppdraget

Syftet med rapporten var att med utgångspunkt i den reviderade versionen av förskolans läroplan, Lpfö 98, belysa hur man som yrkesverksam i förskolan upplever den numera framskrivna och allt tydligare åtskillnad i uppdrag mellan förskolans olika yrkeskategorier, främst förskollärare och barnskötare. Vidare belyser rapporten förskolepersonals tankar och åsikter kring förskolechefens uppdrag: - Hur

Factors controlling Si export from soils: A soil column approach

The release of dissolved silicon (DSi) from A and B horizons was investigated with leaching tests on unsaturated columns. As forest A horizons have larger biogenic Si (BSi) pools than arable lands, we compared the Si release from a forest and a cropland from the same geographical region developed on a Luvisol in Belgium and a Cambisol in Sweden. The A horizons released a quickly dissolving Si frac
