Den här rapporten har skrivits som en del av ett examensarbete på energiingenjörsprogrammet på Högskolan i Halmstad under våren 2014. Examensarbetet har genomförts i samarbete med AB Färdig Betong samt ÅF Infrastructure AB i Göteborg.Syftet med projektet är att undersöka energibesparingspotentialen hos AB Färdig Betongs produktionsanläggning på Ringön i Göteborg.Projektet har inneburit en energikartläggning av en industriell produktionsanläggning för lösbetong. Utgångspunkt för energikartläggningen har varit energiledningssystemet ISO 50001, med målsättningen att ta fram en teknisk energikartläggningsrapport i enlighet med standarden.Anläggningen har analyserats ur ett energibesparingsperspektiv. Data- och informationsinsamling samt mätningar har genomförts för att ta fram indata som beräkningsunderlag. Genom beräkningar har sedan möjliga energibesparingspotentialer och åtgärdsförslag tagits fram.Den totala energibesparingspotentialen för anläggningen innebär en besparing på 223 MWh av anläggningens totala energianvändning på 857 MWh år 2013, vilket motsvarar en minskning med omkring 26 %.Allmänna slutsatser är bland annat att all produktionsutrustning bör placeras inom klimatskalet, att all uppvärmning bör vara temperaturreglerad samt att ett mer långsiktigt energiperspektiv behövs i anläggningen.Energibesparingsmöjligheterna för anläggningen är mycket goda och investeringskostnaderna är i allmänhet låga..

This study describes what impact activity within Wifstas, Matfors,Grönstas and Nolbys water protection areas have on the quality of the drinkingwater. It considers the use of the area, environmentally dangerous activitiesin the past and present, the geology?s part, what harm hydroelectric power damsmay cause if they break and how climate change might affect the area in thefuture. It also takes into consideration activities outside the waterprotection areas which might have a suspected impact on the water quality. Theresults of the study are that pollution from infrastructure such as roads, orwastewater from treatment plants may cause occasional contamination of thedrinking water, foremost due to flooding.

Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

For organizations that handle sensitive information, IT governance and information security are necessities in order to maintain credibility and to conduct its business efficiently. There are several known processes to increase security governance ? which is a fusion of information security and IT governance.This master thesis examines if organizations use recognized processes and if it in that case would lead to higher security. The study is qualitative and conducted in the financial sector and based on Best Practice frameworks of the security governance in Swedish banks. Data collection was done through interviews and surveys that were triangulated to get a gathered picture of the quality of the security governance activities.

Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..

För att informationsöverföring över publika nät ska kunna utföras på ett säkert sätt krävs identifiering, signering och kryptering, vilka är grundstenarna i en elektronisk signatur. Dessa delar i kombination ger oss bl.a. säker e-handel. Som plattform för detta ligger PKI (Public Key Infrastructure), vilket är samlingsnamnet för lösningar där man med hjälp av en speciell krypteringsteknologi skapar system för identifiering, kryptering och integritetskontroll (Halvarsson & Morin, 2000). Systemen kan användas för att till exempel skapa elektroniska signaturer för olika typer av avtal, säkra elektroniska transaktioner, identifiering av användare, säker e-post, och olika typer av säker kommunikation över publika nätverk.Tekniken lovordas till stor del, men även dess brister förs fram av kritikerna.

One of the distinguishing features of successful societies is the ability to adapt to change, bothsocial but also natural changes like climate change. Climate change is a complex, dynamic,non-linear process with a great deal of uncertainty concerning the time perspective, risks andconsequences. A combination of factors like climate change, geographical vulnerability, adensely populated and highly built up coast line along with factors like deficient handling ofsurface runoff and a large usage of ground water leads to an increasingly vulnerable society. Italso puts a greater pressure on the society to have preventive measures in place.The number of actors working with preparing society to the expected impacts of climatechange and variability is increasing. However more than half of Sweden?s municipalities donot consider changing climatic conditions when planning, and many times even allow theconstruction of new living areas in known climatically vulnerable areas.

In the year 1783 a fissure eruption from Laki in the southern part of Iceland produced a large amount of volcanic gases during a period of eight months. The volcanic gases and aerosols spread across the northern hem sphere due to ideal weather conditions and had a substantial impact on the environment, human health and also climate effects. This, so called dry fog, caused severe health problems, which led to death casualties, killing animals, crops and other vegetation. The consequence was a widespread famine which was aggravated by a hard and long winter in 1783/84. Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden.

Yeast and Clostridia is a problem in silage for farmers as contaminated silage may result in poor animal health and milk quality. Clostridia can produce toxins that, when consumed, acts as neurotoxins, it may also cause blown cheeses if the Clostridia contaminates milk. The purpose of this study was to investigate the cause, effect and interaction of yeasts and Clostridia in silage. Clostridia are microorganisms which are strictly anaerobic and consume carbohydrates and protein in the silage. Yeast is a fungus that is facultative aerobic and feed on carbohydrates in the silage.

There is a mutual dependency between the business world and the country?s municipalities. The municipalities are dependent on the companies to create work and tax income while the companies are dependent on the municipalities they are located in to provide good infrastructure among other things.Apart from this the municipalities can work activly with creating a strong brand in the eyes of the companies and many researchers in marketing agree that marketing of places will be more common in the future. Marketing of municipalities is however still a rather new and unexplored area and it is uncertain how and to what extent the municipalities work with this.The thesis is formulated:How are the municipalities working to market towards companies and is it possible to make out any positive change from these marketing efforts?The goal of this study is:Our goal is to examine how the view of marketing of places differs from different municipalities in the Stockholm region, how some of these municipalities work with this and how far they have come in this work.

This thesis examines the ongoing European political debate on the links between livestock production and climate change. In the end of 2006 the UN Food and Agriculture Organization (FAO) released their report Livestock?s long shadow, showing that livestock production represents some 18 % of the total global greenhouse gas emissions. The purpose of this paper is to explore the European Commission?s position and response to this question since the release of the report.Using Arne Naess? argumentation analysis, statements made by the Commission will be systematically organized and broken apart.

Hållbar utveckling har, allt sedan Brundtlandrapporten 1987 och Rio 1992, utgjort den fundamentala idén för långsiktiga miljö- och utvecklingspolitiska strävanden och kommit att dominera miljöpolitiken/policyn i många länder. Med utgångspunkt i Hajers teori om diskursiva strategier för ekologisk modernisering, studeras i denna uppsats (1) hur hållbar utveckling påverkat svensk miljöpolitisk diskurs samt (2) hur den diskursiva dynamiken kring skiftet i svensk miljöpolitik - från kretsloppstänkande och Agenda 21 till ekologisk modernisering - efter socialdemokratins nya vision om 'det gröna folkhemmet', bör förstås.I en fallstudie i Malmö studeras närmare hur förändringen av den miljöpolitiska diskursen återspeglas i en lokal kontext samt huruvida det är nationell styrning, lokal logik eller ömsesidiga samspel inom ramen för de diskursiva förändringarna som gör att den lokala praktiken 'blir vad den blir'..

This essay is derived from a case study about the SIRA school in Betlehem. SIRA is classified as a special education school with financial support from the Swedish International Relief Association. SIRA acts to provide support for children with reading and writing difficulties in their daily school work.The study's aim to describe the context for SIRA's specialized educational activity. The formulated questions should provide answers to which factors that influence SIRA's work, its goals, development, and the distinguished pedagogical approach.During the research comprehensive interviews were conducted with parties which can influence the way schools operate and provide the necessary support for students. Factors that influence the school's operation are analyzed from a ecological development perspective created by Urie Bronfenbrenner. The theory advocates that a student's development and interaction mainly comes from participating in activities, social roles and relations.This constant process of mutual adaptation between the developing individual and its surrounding environment is to be defined as its own entity. The result shows that SIRA's practice a special educational operation with focus on an approach which strengthens the student's identity and communicational skills..

SammanfattningSyftet med den här undersökningen är att ta reda på hur barns tankar kring ekologiska processer kan utvecklas, samt att ta reda på vad i undervisningen som anses vara avgörande för att förmå barn att utveckla sina ekologiska reflektioner. Kvalitativa intervjuer och ett undervisningstillfälle ligger till grund för undersökningen. Därefter sammanställdes och kategoriserades barnens ekologiska processtankar. Resultatet av undersökningen visar att förutsättningen för utvecklande undervisning, är pedagogens kännedom om barnets individuella erfarenheter. Det är utifrån dessa som barnet tar emot ny kunskap och sedan kopplar ihop den med tidigare upplevelser.

The Swedish forest policies have earlier mainly been focused on two goals: production and environment. The production goal aims to benefit the economical gains from forestry while the environmental goal primarily aims to shield the ecological values of the forest. With the introduction of the Swedish environmental code and the environmental objectives it was made clear that the overall objective for Swedish community development, including the forestry sector, is sustainable development. Sustainable development includes supporting economic, ecologic as well as social values of which the latter seems to have been forgotten in the forestry sector. This was recently brought to attention to the sector and the debate how to handle the social values is now ongoing.The legislator has not been unaware of the social values since they have since long been at least somewhat included in the preliminary works.
