… be accepted as a fertiliser and permeate that falls below emission limits. The experiments were carried out with an RO plant with three membranes in series operated in batch mode; the dimensioned permeate flow being 100 l/h. The incoming water was permeate from a membrane …
… were extensively studied during a 24-hour period respectively. Two capacity experiments were performed in order to evaluate the organic reduction at different organic loads. The obtained results together with an estimation regarding the organic load performed by AB …

… the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined …
… in this report is mainly based on simulations in Matlab, even though some experiments have been performed on laboratory equipment. The conclusion indicates that simple non-linear models with few states can be more accurately estimated with a Kalman filter than with an extended …

… quality, wood exchange and higher runability of the paper machine. Several experiments have been done with simultaneous forming of different fibres by placing a fibre with high bulk in the middle layer and a smooth fibre on the surface layers. The results has shown that by using …

… researcher must be a person with experience in growth annuli. Through my own experiments with archaeological and modern bone material, I experienced the difficulty of determining the last growth ring, which shows the season of death on the vertebra. In conclusion, the use of …
… harvest, indicating a need for an effective weed control. The data from these experiments was then compiled to form graphic presentations for each of the species. These graphs show the relationship between the development of black nightshade and peas, and can be used to predict …

… but for every district to deside for themselves and this has led to different ”experiments” with students not mentaly fit for school at all. The society and the school system has nothing to offer but a system when all they really need is TLC.
… Däremot antyder undersökningen att det är viktigt att ha kontroll på en experimentsituation.
… and the content of nitrogen oxides as output is derived. This is done with experiments in the boiler and system identification. The system is modelled as a linear system. The proposal about the improved control uses the temperature from a temperature measurement just below the …
… to complete a cycle, that didn’t match reality. We continued by performing experiments on combinations with a few, carefully selected FDA-approved plastics and joint balls with hard, friction lowering coatings. The temperature in the ungreased plain bearings was measured during …
… assembly with a certain tightening moment with certain lubricate condition. Experiments of the prestressing force in the screws have shown that this becomes smaller than expected at tightening without lubricate. On the other hand, screws with lubrication risk to get to high …
… simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and …
… introduced in the book "The Media Equation" by Reeves and Nass. One of their experiments concluded that we tend to be polite to computers in the same way as we are to people. In this study I have replicated Reeves and Nass experiment but instead of a text-based interface I have …
… Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the …
