Stenmjöl eller naturgrus i betong : En jämförande studie

 The objective of this thesis is to examine the difference in workability in fresh concrete, when crushed fine Aggregate replaces natural gravel. The shape of the fine Aggregate,  packing and flow of six crushed material and three natural materials will be determined by easy studies, the results will be compared with a slump cone test..

Att mäta fattigdomsbekämpning - En studie av social performance-rapportering inom mikrofinans

This study has a double purpose. First, it explores and maps out the use of quantitative key indicators in social performance reporting within a microfinance portfolio. This was done on behalf of Storebrand Asset Management, who would like to Aggregate and report the social results of their microfinance investments to their customers. The study concludes that the extent of social reporting and types of indicators used varies, meaning that it is hard to Aggregate data for use in further reporting. Thus, the work towards the goal of social reporting has only just begun.

En studie om framtida bergmaterialbehov i Arvidsjaurs och Arjeplogs kommuner

Examensarbetets mål är att beskriva och beräkna Arvidsjaurs och Arjeplogs kommuners framtida bergmaterialbehov med utgångspunkt från bygg- och anläggningsprojekt som pågår och som planeras. Syftet är att få en sammanställning som visar om materialet räcker till eller om det finns behov att öppna nya täkter. Sammanställningen kan med fördel användas av kommunerna som planeringsunderlag beträffande nya vägbyggnadsprojekt. Alla tillståndsgivna täkter i Arvidsjaurs och Arjeplogs kommuner har kartlagts och täkternas kapacitet har också tagits fram. Även alla pågående och planerade vägarbeten kommunvis och årsvis från år 2005 fram till 2009 har karterats.

Svinnoptimering VTIS1

The goals of this Bachelors? Thesis were to establish the production loss through the VTIS1 Pasteur at Arla Foods Linköping dairy and then suggest simple but effective solutions to minimize the losses for each production run. If the timeframe allowed it, some of the solutions would be implemented and tested in full production to determine their impact on economic and environmental savings.The very first step of this project was to establish the statistics over what losses there is in the production pipeline through VTIS1, from milk and powders in mixer tanks to finished and packed products in cold storage. Then, when knowing how much product was actually lost and where, those bottlenecks could be pinpointed and examined more closely. At this stage the focus was switched, from the otherwise complicated and broad manufacturing process, to the VTIS1-Aggregate, since early data indicated there were quite substantial losses there.In conjunction with this project Arla Foods purchased an absorption photometer-measuring device (OPTEK AS16) that could be inserted straight into the product stream out of VTIS1, allowing real time measurements of its optical density.

Värmeförluster vid utvändigt placerade ventilationssystem

To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.

Hur bemöts Kina i Afrika? : En mångdimensionell idealtypsanalys av Sydafrikas, Zambias och Zimbabwes bemötande av Kinas ökande ekonomiska intresse

The outset of this study is to contribute to the literature concerning China?s increasing economic interest to engage in the African context, its economies and resource abundandce. The overarching research problem is that the approaches held by the respective African state entities may facilitate increasing development gains for the recipient state of this economic interest in principle. To adress this research problem the study is undertaken by conducting a comparative case study where three cases/states, with presumably diverging economic and political status, are likely to effect their overall state approaches differently.Research questions, which are addressed by the creation of an idealtype analytic matrix, concern whether the states of South Africa, Zambia and Zimbabwe take on a more ?permissive? or ?restrictive? approach towards China?s economic interst and whether the approaches can be looked upon on both aggratege and case/area-specific levels.The main findings are that a clear tendency of the ?permissive approach? may be noted on a Aggregate level for all cases.

Försök med olika såmaskiner vid konventionell sådd och direktsådd

In this thesis, two studies with different drills were included. In one of the studies two drills were compared: Väderstad Rapid and Väderstad Spirit. In the other study various drills for direct drilling were compared. The study with Rapid and Spirit was placed in two locations with different autumn tillage; one on ploughed land in Uppsala and one on cultivated land in Västerås, both with relatively high clay content. Rapid drills have a single disc coulter, while the Spirit drills have a double disc coulter. Various aspects were compared such as Aggregate distribution, seed placement, emergence, crop yield and economic outcome.

Online Brand Community in Action. A Constitutive netnography: Advancing a Wholesome Ethnomethodological Perspective on Brand Community

This thesis advances an explicit, consequent, and wholesome ethnomethodological perspective on brand community. It recognizes brand community as a social problem ? something to be continuously solved and achieved. The two main perceivably stable features of the Nikonian community are (1) practical usefulness and (2) the social link. The authors suggest that both features are constantly accomplished through three types of Aggregate behaviour (1) lurking, (2) ordinary membership, and (3) community citizenship behaviour (CCB).

Inverkan av flisig krossballast på betong

Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as Aggregate in concrete in order to replace natural Aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

Påverkas miljökuznetskurvan olika av ekonomisk frihet än av demokrati

According to the theory of environmental Kuznets curve there is a relationship between carbon emissions and GDP. The relationship has an inverted U-shape. Carbon emissions rise initially and then decreases once a certain level of GDP is obtained.This essay interprets earlier studies in the field of environmental economics and uses public choice to seek answer on how the population acts on Aggregate level. This essay analyses 115 countries in cross-sectional data. The analysis shows that there is a significant relationship between carbon dioxide emissions and GDP that is increasing at first and then decreases for a certain level of GDP.

Övergång till helkrossballast : En studie för Strängbetongfabrikerna i Veddige och Herrljunga

This exam report has been developed in association with Strangbetong AB, Sweden.The natural gravel that is being used as fine Aggregate for concrete production today is an ending natural recourse and the Swedish government has decided to strongly reduce the extraction from the year of 2020. The only reasonable replacement is Aggregates from crushed rocks but this material has other properties than natural Aggregates. The concrete manufacturers now have to learn how to use these new fine Aggregates in a cost effective way in order to ensure the quality of their concrete production.In this project, crushed Aggregates and combination of crushed and natural Aggregates have been tested with existing formulas for fresh concrete. The two parameters yield stress and plastic viscosity have been measured which gives a good description of the workability of the fresh concrete. Different methods to make measurements on the dry fine Aggregates, has also been tested, to find out if there is any correlations between these parameters and the parameters from the measurement on the fresh concrete..

Produktionsskillnader vid olika antal sortiment

This study is done together with Sydved AB in the summer of 2012. The purpose of the study is to analyse how different quantity of assortments influence the production for forwarders and harvesters with multiple tree handling Aggregate in thinning, by different tree volumes. To make this analyse a time study was performed where three entrepreneurs work has been analysed. Beside the analyse, of different quantity of assortments, has also been analysed how the tree volume and a forest fuel assortment effect the production. The result of this study shows that the quantities of assortments have a significant meaning for the production. The biggest differences are most distinct between one and three assortments in the smaller tree volumes where production goes down if the quantity of assortments increase.

EU:s tjänstedirektiv - ursprungsprincipen eller destinationsprincipen?

The Vaxholm conflict was initiated when the Swedish Trade Union for Construction Workers shut down a construction site in order to prevent a Latvian construction company to build a school after the two parties had failed to agree upon a collective agreement in compliance with Swedish regulations. An emotional public debate followed that resulted in a discussion of the proposal for the Services Directive of the EU, based upon the country-of-origin principle. In this thesis we will analyze whether the country-of-origin principle or the country-of-destination principle is best suited to capture the gains-of-trade that the common market hoards and improve welfare within the EU. We conclude that the country-of-origin principle is the more apt of the two, though it leads to some short-run costs such as structural unemployment. But these will be more than outweighed by the gains in Aggregate welfare for the EU in the long run..

Lägesbild : Problemområden vid skapandet

Within the framework of the concept of Network Based Defence (NBF) services should be available in the network, in order to increase the Aggregate capacity. A common situation picture is one of these services.The aim of this paper is to answer the problem "What are the main problem areas in the creation of a situation picture in the land arena, with the help of the technical sensors that exist today?" and to develop a basis for continued research in the field situation in the concept Networking Enabled Command, Control and Collaboration (NEC3) at JCDEC (Joint Concept Development and Experimentation Centre). To answer the problem, a descriptive method is to be used in descriptions of the land arena, the information arena and the sensors and a deductive method is used when analyzing the asensors in the land arena.The problems that exist in the creation of a common situation picture, is that different types of obstacles makes it difficult for the sensors, the large number of people who are not combatants and that it is difficult to judge if a civilian vehicle is a threat, then it could be driven by civilians or by combatants..
