Målet med examensarbetet är att som projektledare utföra en förstudie, planera samt genomföra ett switchbyte i en blandad klient och servermiljö med flera huvudmål: Att minska befintlig offertkostnad, minska det dagliga underhållet, se till att de nätverkskopplingar som används verkligen används, säkra upp redundans för både server- och klientnätverkskopplingarna, se till att dagens och framtidens krav för klientsidan samt serverhallen uppfylls på huvudkontoret för Xylem Water Solutions AB i Sundbyberg.Under projektets gång formades en plan och den följdes sedan till att byta från Nortelprodukter till ett nytt, stabilt nätverk uppbyggt av Ciscoprodukter, Nexus 5548P och 2248 för core/serveraccess-switchar och Catalyst C2960S-switchar för klientaccess..

Vattendirektivets (2000/60/EG) krav på skydd och bevarande av vattenkvalitet i vattenförekomster har kraftigt ökat medvetenheten om vattenhänsyn och vattenvård i det svenska skogsbruket. Världsnaturfonden lanserade hösten 2011 tillsammans med skogsägarföreningarna (Södra skogsägarna, Mellanskog, Norrskog och Norra skogsägarna) vattenhänsynsverktygen NPK+ (Naturvärde, Påverkan, Känslighet och Plusvärde) och blå målklassning som hjälpmedel till skogsägare för att ta och synliggöra vattenhänsynen. Relevansen hos verktygen NPK+ och blå målklassning att identifiera och klassificera vattendrag efter vattenkvalitet undersöktes med antalet fiskarter som indikator på vattenkvaliteten. 55 vattendrag i Krycklanåns avrinningsområde strax utanför Vindeln i Västerbottens inland inventerades med NPK+ och blå målklassning i mitten av september 2011. Fältinventeringsdata analyserades statistiskt med fiskartsförekomst från en tidigare elfiskeinventering i vattendragen.

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.

This master thesis has been performed at the department of Machine Design at KTH, The Royal Institute of Technology.

Corporate liaison and sponsor has been Immerse Global Inc. The project was also performed on sponsorship from the Product Innovation Engineering Program, PIEp. The thesis is a representation of some of the contributions made by the authors.The lack of clean drinking water is one of the key issues facing the world today.

The question of whether there is soft law in international law has been as much the subject of contemporary debate as whether or not there is private legal authority in the international society. The legal boundaries seem to be blurred by the process of globalisation and the recent shift in international law. The traditional definition of international law has been outdated as new forms of treaties has introduced new subject of law to the judicial arena. At the same time a supplementary map of law has been added to the cartography of international law, soft law. These correlating processes have comprehensive political and legal consequences at both the international and national levels.

Researchers and practitioners have recognized the need for ?transforming? every policy of the company into a competitive advantage tool. Thus, both the pricing approach and the supply chain practices of the firm have emerged as an important determinant of success. In this study, however, we are not only interested in these two aspects, but also in a third one-namely cultural conflicts as an obstacle and challenge. The interaction of the tree factors is extensively presented against the backdrop of Skanska and four of their closest Polish suppliers.

Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.

Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.

Problem StatementAfter the hurricane Gudrun in January 2005 EON Elnät Sverige AB started the project KRAFTTAG, were 17,000 km of the airborne power grid shall be replaced with cables underground. The transformers in the airborne power grid shall be dismounted, renovated if necessary and then conveyed to stations, of type kiosk.Additional new transformers, more than planned, have been bought. This is due to the dysfunctional transformer flow from the demolished power supply to projects, were the new power supply is built, the general picture is complicated, since the reconstruction involves other companies and many employees at E.ON.PurposeThe purpose of this master thesis is to map and understand the existing transformer flow. The objective is to make a recommendation on how to increase the level of E.ON? s transformer recycling.Methodthe authors have worked with a system approach, including both qualitative and quantitative data.

Today all private corporations are obligated by statutory audit. The government of Sweden appointed an investigation to conclude if the audit should be statutory or not. The investigator presented on the third of April 2008 a report (SOU 2008:32) that suggests abolishment of the statutory audit for approximately 97 % of all private corporations in Sweden. This will result in certain effects on the banks credit rating because of the fact that the banks trust the audited accounts to have been audited by an independent audit.The most important in the banks credit rating are: personal judgement, business concept, business plan and repayment ability. The banks also use the private corporations audited accounts in its credit rating.We conducted a case study by interviewing four bank officials in different banks in Skövde and Tibro.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

In article 1.2 c) EC regulation 852/2004 it says that the regulation is not applicable to producers who directly supply small quantities of primary products to the final consumer or to the local retailers who in their turn directly supply the final consumer. An almost identical regulation can be found in article 1.3 c) EC regulation 853/2004. The supply by a primary producer of small quantities of primary products, of animal origin or not, are consequently excepted from these two hygiene regulations. In article 1.3 EC regulation 852/2004 and article 1.4 EC regulation 853/2004 it says that the member states are to establish national rules in their national legislation as to the regulation of exception for small quantities. The aim of this study was to investigate the handling of small quantities of primary products distributed locally in Sweden but also the handling of these products in other countries.

Most of the city of Uppsala rests on postglacial clay with a varying content of sulphur. The sulphur occurs naturally in the clay in reduced form as sulphide and the clay is for that reason usually called ?sulphide clay?. Excavation during construction activities gives rise to large amounts of excavation material, of which the sulphide clay is a considerable part.When the clay is exposed to air and water, an oxidation of the sulphides occurs which may produce an acid leachate and the mobilisation of heavy metals bound in the clay or underlying material. The aim of the work has been to improve our understanding of the behaviour of sulphide clays and produce a basis for risk assessment in the future handling of excavation material with high sulphide content.

Increased energy consumption in the world has created an increased supply of various fuels, especially fossil fuels. The Swedish government has set up various energy targets for 2020. To reach these goals it?s important to increase the energy efficiency in local buildings such as schools. This work illustrates the breakdown between energy supply and energy losses over the school.

Derome Skog AB is a purchase company whose main task is to provide Derome Timber's sawmills in Halland with timber raw material. Because of the very hard competition in the roundwood market it is important to know what kind of purchase offers are required in order to buy a valuable product from forest owners.This study aims to elucidate the crucial factors when private forest owners choose to harvest and sell their forest. As base for this study, a questionnaire has been performed with private forest owners. The result of the study shows that it is not particularly often that the timber price is the crucial factor why the forest owners choose to harvest and sell the forest products; i.e. timber, pulpwood as well as energy assortments.
