The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.

Syftet är att genomföra en utvärdering av produktivitetspotentialen på Gnutti i Kungsör och dessutom komma med förslag på lämpliga åtgärder som kan resultera i en förbättrad produktivitet. Effektivitet i maskinutrustning mäts i OEE, Overall Equipment Efficiency, vilket på svenska står för den totala utrustningseffektivteten. OEE-talet baseras på faktorerna tillgänglighet, effektivitet och kvalitet. Det primära målet för vinstdrivande industriföretag är att skapa lönsamhet genom att förädla sina produkter effektivt och då måste fokus på att mäta produktionseffektiviteten på rätt sätt finnas. För att mäta hur väl ett produktionssystem använder sina resurser kan OEE-mätningar utföras.För att kunna mäta den verkliga produktiviteten och dessutom kunna komma med förslag på lämpliga åtgärder för att höja OEE-talet anser författarna att en lättarbetad och konkret metod för produktivitetsutvärdering är lämplig att utgå från.

Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.

This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.

Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.

To investigate the possibilities for effective soil tillage, that could imply lower costs, lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006. The experiment contained two treatments that were repeated three times and were carried out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the other. The experiment was conducted according to the guidelines of organic growing and seedbed preparation was done the same way in the two treatments. The pigs, three groups of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform an even tillage by strip-grazing, i.e.

Sitka spruce (Picea sitchensis (Bong.) Carr) is just like Norway spruce (Picea abies) a species in thegenus picea. The natural range of Sitka spruce is a narrow strip along the west coast of North America. Itis the most coastal of all picea species, and very dependent on the mild and humid climate along thepacific coast.Sitka spruce has been grown a long time in the countries around the North Sea, particularly in GreatBritain where it currently is the most important species in British forestry. Sitka spruce has not beenplanted in Swedish forests to any large extent before the storm Gudrun in 2005. Several studies indicatethat the production of wood biomass is higher for Sitka spruce compared to Norway spruce.

AbstractDegree thesis Solid content in Lime Mud By Andre Flodin Process operator program ? Umeå University 17/6 ? 2014 Pages: 21A thesis was made on Billerudkorsnäs production unit in Karlsborg where lime kiln in the causticising department of chemical recovery plant does not meet the required production. Causticising department is the final step in the chemical recycling unit. There, the filtered green liquor is mixed with lime to recover the cooking chemicals used in the pulp factory. The cooking liquid is called white liquor.

The Angola black-and-white colobus (Colobus angolensis palliatus) is a subspecies of Colobus angolensis inhabiting fragmented forests in coastal Kenya and Tanzania. C. angolensis is regarded as Least Concern in the red list of IUCN because its populations are abundant. However, the populations of C. a.

AbstractFalu Copper Mine and Sustainable DevelopmentKarl-Markus AnsnaesFalu copper mine was Sweden?s oldest mine industry which lasted for almost a thousand years. Throughout the history its area has been vastly contaminated by sulfur oxide. The contaminations has created the mining area to an environmental risk zone which has the ability to spread out into the Falu River. The river has its connections to the Dal River which is discharging towards its mouth in the Baltic Sea.

Stem rust, Puccinia graminis, has caused enormous yield losses throughout history which have had significant consequences for oat and wheat production. Today in Sweden stem rust is only reported from rye, oats and wild grasses. Stem rust infections in wheat have become unusual due to the general use of resistant wheat varieties and also due to the eradication of barberry, Berberis vulgaris, the alternate host for P. graminis. According to international sources, new races of P.

The purpose of this thesis was to determine what materials should be used when creating a stimulating garden for intellectually handicapped people and whether there are materials that are better than others to use in this kind of environment. How the materials preferably can be used and how the environment should be designed to satisfy the need of each individual will also be discussed. Seriously intellectually handicapped people have the same level of intelligence as a normal 0-2 year old child. It is important to point out that these individuals can not be compared to a normal child in other aspects than the level of abstract thinking and perception of reality. As the grown up intellectually handicapped people have remained a lot longer on this stage of intelligence they have got more experience. (Kylén 1981) It is important with a lot of different experiences for the brain to develop normally, which implies the use of many different materials to achieve the best stimulation (Kylén 1981).

Den ökande inflyttningen till städer ställer oss inför ett oundvikligt ställningstagande angående hållbar stadsutveckling. Städernas förtätning minskar grönområdena vilket gett vissa urbana miljöproblem, exempelvis översvämningar, lokala temperaturhöjningar och försämrad luftkvalitet. Ett sätt att förebygga dessa problem är att återställa de förlorade grönytorna genom att bygga gröna tak. I Sverige har utvecklingen av gröna tak pågått i ungefär 20 år, med störst fokus på de miljömässiga positiva egenskaper de besitter. Det här arbetet handlar om gröna tak i Melbourne, Australien och fokuserar, genom bland annat intervjuer, på vilka sorts tak som byggts, när, hur och varför. Det finns tre olika typer av gröna tak; extensiva, semi-intensiva och intensiva.
