Potential för värmeåtervinning från mjölkkylanläggningar

The present climate discussion has made energy efficiency an interesting topic. Saving energy does not only help the climate but also saves money for the energy consumer. The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two milk farms, one with voluntary milking system, VMS, and the other with conventional milking system was used to measure interesting temperatures and electricity consumptions. The numbers were used both to do theoretical calculations and to construct a SIMULINK model. To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using a reference farm with different combinations of heat recovery and pre cooling. The farm was assumed to keep a dwelling house with the annual heat consumption 18165 kWh.

En pilotstudie av unghästars användning av ligghall i grupphållningssystem

Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. One of the alternatives to the traditional format in individual boxes is called group housing. Group housing systems allow horses to live in herds and they can choose how they want to distribute the hours of the day between movement, resting and foraging. The purpose of this study is to examine how frequently the young horses in a group housing system use the indoor lying area.

Miljöbyggnad i ombyggnadsprocessen : Miljöcertifiering av Jakobsbergsskolan i Kristinehamn

Climate change is an increasingly widely known concept. In the EU the construction sector is responsible for more than a third of the carbon dioxide emissions and 40 % of the total energy use. In Sweden, measures have been taken to prevent this climate change. By 16 targets, three of which can be linked to the construction sector, Sweden will reduce the negative trend. None of the three goals with relation to the construction sector will however be achieved before 2020.

Klimatflyktingar, en fråga om samarbete? : En studie om internationellt samarbete i kontexten klimatflyktingar

I takt med att de globala klimatförändringarna fortsätter kommer konsekvenserna bli allt mer ödesdigra. Vissa av dessa konsekvenser förbises ofta i den globala debatten och i världspolitikens inflytelserika kretsar. Uppskattningar gör gällande att så många som 200 miljoner människor blivit förskjutna som en konsekvens av klimatförändringarna. Detta aktualiserar frågan om klimatflyktingar. Syftet med denna uppsats är att studera varför det internationella samarbetet gällande klimatflyktingar kan betraktas som begränsat.

Medarbetares uppfattning av säkerhetsklimatet: Skillnader utifrån anställningsår och anställningsform avseende ledningens och arbetsgruppens säkerhetsarbete

Syftet med föreliggande studie var att undersöka om det fanns någon skillnad mellan de som varit anställd få respektive många år samt mellan de som arbetade dagtid och de som arbetade skift gällande uppfattningen av säkerhetsklimatet avseende både ledningen säkerhetsarbete och arbetsgruppens säkerhetsarbete på ett bruk inom massa- och pappersindustrin. Totalt deltog 92 medarbetarna i studien och dessa fick besvara frågeformuläret, Nordic Safety Climate Questionnaire (NOSACQ-50). Resultatet visade att de som arbetat många år uppfattade både ledningens och arbetsgruppens säkerhetsarbete som bättre än de som arbetat få år. Det visade sig även att de som arbetade dagtid uppfattade, om än bara i närheten till signifikant, ledningens säkerhetsarbete bättre än de som arbetade skift. Att ha en förståelse kring att det finns skillnader i uppfattningen av säkerhetsklimatet och vad dessa kan bero på kan vara av vikt för att skapa ett bättre säkerhetsarbete på företaget, något som diskuteras i uppsatsen..

Rening av lakvatten vid deponin Degermyran i Skellefteå kommun : Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar

At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.

Vem bryr sig? : Ett kommunikativt perspektiv på fusionen mellan Växjö Universitet och Högskolan i Kalmar

This essay takes the three models from Allison and Zelikow book Essence of decision and applies them on the Swedish defense system. After the cold war the Swedish defense system had to undergo changes to be a more modern defense and be able to defend Sweden against threats. To also be able to cooperate with other countries in peacekeeping operations the Swedish defense had to be reorganized. The solution was to change direction from a defense system that was organized for invasion to instead be a movable defense ready for any challenge in Sweden or abroad. This reorganization will be analyzed according to the three different models..

Fuktsäkert byggande : Sjönära bostäder i Östra Hamnen i Västerås

Housing construction very close to the lake Mälaren has become very popular today. One potential problem with these houses is the influence of the sea climate. Unprotected buildings are affected by strong winds and precipitation. So for that reason, it is very important to make an accurate climate investigation and use it for decision-making during the planning of the new settlement.It is very important with a good moisture protection regarding pelting rain, that is the combination of wind and rain. This is more important for buildings close to a lake, as this location normally means a higher exposure to wind.
