Cementstabilisering av Biltemas andra lagerbyggnad i Halmstad

This is a technical report about cement Stabilization in general and the Stabilizationprocess during the construction of a warehouse in Halmstad, Sweden in particular and iswritten at the section for economy and technology at Halmstad University incollaboration with NCC Anläggning.NCC encountered variations in compression strength in the stabilized material on the firstwarehouse that they constructed for the company Biltema. In our report we used theStabilization process of the second warehouse for the same company as a reference todetermine what could be done to get a more homogeneous result for future projects.We also looked in to what testing method is the most suitable to determine the result ofthe Stabilization.After interviews with people involved in the process and visits on the work site we havecome to the conclusion that the most probable cause to the variations in compressionstrength is segregation in the ballast material. This segregation can occur in severaldifferent occasions in the process such as during the production, transportation andhandling on the work site.Other causes for the variation can be improper compaction, overlapping Stabilization insome places and different duration of hardening of the samples that are tested.The best way to do in situ test of the stabilized material is to do seismic investigations asthose are non-destructive tests in comparison to taking core samples and you can discoverany cracks or air bubbles in the material..

Den djupa muskelfunktionen hos kvinnliga elitvolleybollspelare : En studie om transversus abdominis funktion påverkas av stabilitetsträning.

Background and purpose: Volleyball requires a lot of the human body, andeffective core stability is necessary for the athlete. Our muscles cooperate as achain of motions and core Stabilization is the base for the moving muscles.The most well-known Stabilization muscle is m.transversus abdominis (TrA).The purpose of the present study was to evaluate the function of TrA inSwedish female elite volleyball players and to observe the influence of eightweeks of Stabilization exercise on the TrA. Method: 10 female elitevolleyball players (mean age 24,7 years, range 18-31 years) participated inthe study. TrA was measured in supine position with a pressure biofeedbackunit. Subjects were instructed to draw in the abdominal wall without movingthe pelvis and hold for 10 seconds.

Påverkar euron resultatet av stabiliseringspolitiken? : En studie av stabiliseringspolitikens utfall i de nordiska länderna sedan eurons tillkomst, och av betydelsen av en nationell penningpolitik.

This paper discusses whether the main argument for European countries to stay out of the euro, i.e. the loss in stability from not having a national monetary policy that can be used for Stabilization purposes, is still valid ten years after the introduction of the single currency. We analyse the Stabilization performances of four largely comparable Nordic countries that have all chosen different levels of European economic integration. In retrospect, the so-called ?Stabilization policy argument? seems surprisingly weak.

Effekter av instruktion på transversus abdominis vid stabiliseringövningar

AimThe aim of this study was to evaluate the activity recorded with electromyography (EMG) fine-wire electrodes, in transversus abdominis (TrA) and rectus abdominis (RA) while performing various Stabilization exercises, and to investigate how the level of activation was affected by specific instructionsMethodTen physically active women (27.1 ± 5.5year, 1.74 ± 0.05 m, 67.1 ± 8.6 kg) performed six different Stabilization exercises (four lying supine with bent knees and hips and two in four point kneeling). They performed two sets of exercises, the first without and the second with specific instructions. The specific instruction was ?abdominal hollowing to activate? TrA. The fine-wire electrodes were inserted bilateral into TrA and RA with an injection needle with guidance from an ultrasound.

Är fiberarmerad sprutbetong motiverad ur bärighetssynpunkt? : En jämförelse med traditionell släntning och jordspikning

This thesis is written on behalf of Skanska, Väg- och Anläggning Stockholm Mälardalen, vid Nya Karolinska Sjukhuset i Solna, NKS. The report has resulted in recommendations for the method of soil Stabilizations of soil nailing, excavation of slope and fiber reinforced shotcrete, which is the most suitable method from a safety and a cost point at the NKS.The aim of this thesis was to investigate whether fiber reinforced shotcrete increases slope stability, with the focus being on the total stability. The main goal was to investigate which method of soil Stabilization is the most suitable for the slopes that are analyzed in this report. Through studying literature, the authors have gained an understanding about the theoretical background for the given problem. Through calculations and analyses of the slopes, safety factors have been acquired.

Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam : Chemical stabilization of mine waste with sewage sludge and calcium carbonate residues

Chemical Stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residuesMine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolvedoxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as complexing agents for heavy metals and in this way increase their mobility.

Elasticitetsmodulen i en kalkstabiliserad vägterrass : en fältstudie

Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the Stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.

Aggregerad konsumtion : En ekonometrisk studie

The purpose of this study is to evaluate the real aggregated consumption and empirically determine its exogenous variables. A multiplicative analysis is done in the context of government Stabilization policy to find out how policymakers can execute a stimulus package that will bring the best multiplicative effect to the economy The conclusion of the study is that real income, net financial assets and real-estate price index are all statistically significant. An effective expansive fiscal policy is a public-financed investment in the private sector. Coordination is going to be crucial when stimulus package is developed due to the fact that leakage in the form of imports will prevent the expected multiplicative effect..

Har ökad öppenhet påverkat den automatiska stabilisatorn? : -en makroekonomisk paneldatastudie

This paper investigates the automatic stabilizer and the underlying factors behind its function. The paper includes both a literature review and an empirical analysis. The literature review discusses the IS-LM and Mundell-Fleming models and different ways to quantify the automatic stabilizer. Based on the theory, the relationship between volatility in GDP and the size of the automatic stabilizers is then analyzed with the help of regressions. Our main result shows a negative relation between these two variables.

Risker i flera dimensioner : Om kopplingen mellan designmönstret MVC och projektrisker

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic Stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

HARR (THYMALLUS THYMALLUS) I VÄTTERBÄCKARNA : En studie om samband mellan bottenfauna och harrens förekomst

This thesis aimed to investigate how a rising sea level would affect the livable area of the island Fongafale, Tuvalu. Through the IPCC Stabilization scenarios it was examined which areas of the island that would be affected by flooding. The local population?s perceptions of the effects of climate change were studied to see how the consequences of a world-wide problem such as global warming affect people's lives. The paper clarified the Tuvaluans place in the discussion of climate refugees, explained IPCC's work and described the results of previous studies concerning people in Fongafales perceptions and concerns about climate-related changes.

Rysslands piratisering- Vad gick fel och varför?

The transition from a planned economy to a market economy was initiated in Russia in the beginning of the 90s. The three components: privatization, liberalization and Stabilization constitute the trinity of the transition theory. This thesis has its focus on the privatization, that also can be referred to as a piratization of Russia. The purpose of the thesis is to explain what went wrong with the privatization, and also why it went wrong. A few men, called oligarchs, got their hands on great wealth which has lead to an abuse of power.
