När en stad växer måste man ta ställning till hur det ska ske. Idag är biltrafiken dominerande i Göteborg och i framtiden skulle spårbunden trafik och utbyggd pendeltågstrafik i regionen kunna innebära mer hållbara tranporter. En pendeltågsstation har ett relativt begränsat omland och behöver för fullt utnyttjande bebyggas nära inpå. Den spårbundna trafiken kan dock innebära störningar och risker. Jag undersöker i mitt examensarbete hur en ny stadsdel utanför Göteborg kan byggas ut kring en tänkt pendel­tågs­station.

Denna rapport f?rklarar och j?mf?r implementering av ekologiskt h?llbara initiativ inom tv? tillverkningsf?retag, AB Somas Instrument och Rexcell AB. Genomf?randet av uppsatsen grundades i en kvalitativ forskningsmetod tillsammans med semikonstruerade intervjuer f?r att samla in data. B?da f?retagen verkar inom tillverkningsindustrin d?r Somas tillverkar ventiler medans Rexcell tillverkar papper. Rapporten utforskar de tv? f?retagens h?llbarhetsstrategier, olika utmaningar som uppst?r under initiativtagande och i vilken utstr?ckning de har n?tt sina m?l f?r ekologisk h?llbarhet.

Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

Grunda mjukbottnar i Sveriges kustvatten utg?r biologiskt v?rdefulla milj?er med funktioner som n?ringsoms?ttning, erosionsskydd och viktiga livsmilj?er f?r fisk. Trots detta ?r dessa habitat kraftigt hotade av ?kad exploatering kopplad till bebyggelse, turism och infrastruktur. Studien syftar till att unders?ka hur svenska kustkommuner hanterar skyddet av grunda mjukbottnar i f?rh?llande till befintlig lagstiftning och nationella riktlinjer.

The last decades the populations of wild boar (Sus scrofa) has increased rapidly over the species? entire European range, including Sweden. This is followed by increasing human-wildlife conflicts as a result of the wild boar foraging behavior, causing damage to agricultural crop fields due to trampling and feeding. To be able to minimize damage we need more knowledge of where in the fields the risk of damage is high and what features in the landscape that affect this risk. I analyzed damage distribution in relation to the distance to six different landscape features; forest, road, ditch, building, game field and bait station, in the study area, the Island Mörkö in eastern central Sweden.

This project has revolved around finding better ways of overseeing vibrations of the gearbox at a wind power station. The gearbox has been a huge problem at the stations located at Gässlingen and the sooner the warning of an incoming breakdown is at hand the more money you can save from preparations. The work has been carried out together with Askalon AB in cooperation with consults from ÅF. Askalon is a company with a department focused on overseeing vibrations and it is in collaboration with that department the work has been carried out. During this work, new positions for the sensors and new methods of gathering and analyzing data have been worked out. This was then implemented at a wind power station to be tried out on site.

Bakgrund: Lidande ?r en ofr?nkomlig del av m?nniskans tillvaro. N?r sjukdom, f?rlust eller existentiella kriser drabbar m?nniskan uppst?r ett behov av lindring, ett behov av tr?st. Inom v?rden blir sjuksk?terskan ofta den som m?ter den lidande patienten och ocks? den som b?r ansvaret f?r att skapa ett tryggt rum d?r lidandet kan delas, f?rst?s och lindras.

Sedan industrialiseringen har koncentrationen metan i atmosf?ren ?kat. Metan (CH4) ?r en effektiv v?xthusgas, producerad av metanogena organismer i syrefria milj?er. K?llorna till CH4 varierar brett och ?r b?de antropogena och naturliga.

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

Enligt l?roplanen f?r f?rskolan (Lpf?18, 2018) lyfts vikten av fysisk aktivitet och dess p?verkan p? m?nniskors h?lsa och v?lbefinnande. Dock ?r det bara tolkningsbara str?vansm?l vilket g?r att kvaliteten p? arbetet skiljer sig ?t beroende p? f?rskola. Syftet med denna studie ?r att unders?ka f?rskoll?rares uppfattningar om och erfarenheter av fysisk aktivitet i f?rskolan.

Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact.

In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.
