… Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied. The experiments were conducted with urban storm water and …
En undersökning av reningseffekt med avseende på järn och mangan
… a highersurface load. As an attempt to accelerate the curing of the filter, experiments with a layer ofsand which surface has been covered with manganese ore (MnO2) on top of the filter havebeen done. As test filters 10 L bars were used and the experimental work was performed at …
… circles had a diameter of approximately forty centimetres. The winter wheat experiments I’ve studied show a lower cost for crop-establishing when you reduce the cultivation. Lower costs for the establishing of the crop allow you to accept a lower yield. My experiments show that …
En studie om hur pedagoger arbetar med teknik i de tidigare åldrarna
… preschool, think they use technology every day. They use it in their games, experiments, food situations and even when the children are dressing them selves. The pedagogues in the compulsory schools work with technology, without reffering to the actual concept. They use the …
… textile and glass together. The work is characterized by material and shape experiments with silver and copper weave and hand blown glass. From experiments and sketches, the work has resulted in four sculptures, symbolizing four selected stages in a lifecycle; the birth, the …
… of planting spot may have an impact on resistance to drought two field experiments with different kinds of mini seedlings and scarification methods were carried out in the area of Garpenberg during 2007. The first experiment included three different container depths of mini …
… clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator. From the aggregation experiments, the result seemed to be that SNAP during …
med digital signalprocessor programmeradmed LabVIEW och Matlab
… the processor characteristics and thevarious programming languages used. All experiments that were made on theprocessor are described, these descriptions also help in understanding the annexeswhere the experiments will be presented. The body of this report also describes …
En studie av ureasönderfall under kvävgasatmosfär
… acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e. the temperature at which substances begin to melt, vaporize, decompose and react. In combination with FTIR …
a possibility to reduce nutrient levels and produce commercially interesting metabolites
… as raw material for biogas or animal feed or possibly as biofertilizers. Two experiments on Chlorella vulgaris capability, to grow and reduce nutrient levels in excessive water from greenhouse production, were performed. In experiment 1, Z8 (a standard medium for alga) was …
In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend …
The influence of calcium and magnesium on the expellation of arsenic in the fluidized bed furnace
… calculations were made by the computer programme FactSage and roasting experiments with ore concentrates were performed on a laboratory scale. Simple particle size measurements were performed as well. It could be ascertained that raising the temperature increased the cupellation …
… the cloud becomes apparent. By compiling literature and performing practical experiments, this thesis exposes weaknesses in traditional incident response plans and demonstrates a need for cloud-specific incident response plans.Based on the conducted experiments, we can conclude …
a potential approach to hurry up shelf-life tests on oat products
… The easiest, applie able accelerated approach to recommend, is the shelf-life experiments due to Q10-modeling, were two test temperatures in combination with correlation shelf-life estimations will generate a Q10-factor. The intention with Q10 -modeling is a way to state the …
evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon
… was studied. The removal efficiency of PFASs was studied in pilot-scale column experiments at Bäcklösa drinking water treatment plant (DWTP) in Uppsala, Sweden. The laboratory batch experiments were performed at Swedish University of Agricultural Sciences (SLU), Uppsala. The …
