1. Nodulation and biomass development of yellow and blue lucerne under pH stress
Master-uppsats, SLU/Dept. of Crop Production EcologySammanfattning : Approximately 77% of global arable land use is devoted to forage cultivation, which is the basis for animal production and global food security. Therefore a sustainable and biologically diverse forage cultivation is needed. Feed for cattle needs to contain a good balance between fibre, energy and protein. LÄS MER
2. Optimalt pH-värde i åkermark för en effektiv växtproduktion : vilka rekommendationer finns i andra nordeuropeiska länder?
Uppsats för yrkesexamina på grundnivå, SLU/Dept. of Soil and EnvironmentSammanfattning : En effektiv, lönsam och hållbar växtproduktion vill de flesta lantbrukare i alla länder uppnå. Det är av största vikt att sträva efter ett optimalt pH då det är en variabel som påverkar de flesta kemiska reaktioner och processer i marken. LÄS MER
3. Automatisering av pH-simulering vid testning av ventiler
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : Cytiva Umeå produces laboratory equipment to customers around the world. The Equipment is built by different kinds of modules that is put together to create a finished product. A module that is used in some products is a pH-vent. LÄS MER
4. Exploration of ways to utilize wheat chaff through fungal substrate conversion : a base for animal feed or substrate for cultivation of edible mushrooms
Master-uppsats, SLU/Department of Molecular SciencesSammanfattning : The shift towards a more sustainable food system emphasises a need for increased circularity and valorisation of available resources. Chaff constitutes one of three main fractions obtained upon harvest of certain crops, during which it is generally discarded on the field. LÄS MER
5. Reducing cadmium emissions to water during removal of electrostatic precipitator ash : Investigating the effect of process parameters on the formation and precipitation of insoluble cadmium salts in water solutions
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : The removal of electrostatic precipitator (ESP) ash by solving the ash in water constitutes an environmental problem if heavy metals, such as cadmium, present in the ash remain in the outgoing effluent streams. The ESP ash solution is alkaline, meaning cadmium is present as the insoluble salt Cd(OH)2, cadmium hydroxide. LÄS MER
