En studie av skillnader mellan monotisk och dikotisk 40 Hz Auditory Steady-State Response

ObjectiveThe objective of this study was to investigate differences between monotich and dichotic 40 Hz Auditory Steady-State Response (ASSR) with Interacoustics Eclipse.DesignThe aspects studied are test duration, relation be¬tween ASSR and behavioural thresholds (BT), reproducibility and correlation between rejects during Brainstem Response Audiometry (BRA) and differences between ASSR and BT. Monotic and dichotic ASSR-thresholds for eight normal hearing subjects (.

Undersökning av steady state och utvärdering av valskraft och friktion vid kallvalsning av aluminium

The purpose with this thesis was to examine the cold rolling mill located at Högskolan Dalarna and to stabilize the rolling process, to achieve Steady State. Experiments with cold rolling of an aluminium strip have given results for rolling force, friction, reduction, strip tension and strain hardening. Results show that Steady State has been found for the experiments with roll force and strain hardening, and not been found for the experiments with friction and reduction. Results show that increased strip tension gives lower roll forces. The roll force equation of Stone shows comparable results with reality for dry contact with reductions up to 30 %, but starts being incomparable with higher reductions.

Jämförelse mellan ?Auditory Brainstem Response (ABR) och ?Auditory Steady State Response? (ASSR) för att uppskatta hörtrösklar på barn i narkos. Kan testtiden minska om 500 Hz utesluts vid ASSR-mätning?

ObjectiveThe objective of this study was to investigate the clinical application to use ASSR in anesthetized childrenDesignOne main ambition of the investigation was to compare hearing threshold using ABR with estimated hearing threshold using ASSR. Another aim was to examine if the duration of an ASSR measurement could be reduced by only using the frequencies 1, 2 and 4 kHz and exclude the frequency 0.5 kHz. This is a retrospective study using electrophysiological measurement from a database.ResultResults showed a high correlation between hearing threshold using ABR and estimated thresholds using ASSR, with the frequency 0.5 kHz showing a slightly lower correlation. Result also showed that the test duration was increased when using all test frequencies in ASSR-measurement compared to when 0.5kHz was excluded. ConclusionThe study showed a high correlation when comparing hearing threshold using ABR and ASSR.

Auditory Steady State Response: En jämförelse mellan två kliniska instrument : En experimentell studie

 I denna studie har jämförelse gjorts mellan Interacoustics Eclipse och GSI Audera i samband med Auditory Steady-State Respons (ASSR) mätningar.Syftet med studien var att undersöka ASSR som metod, att utvärdera dess tillförlitlighet i jämfö­relse med tonaudiometri för personer med normal hörsel och personer med hörsel­nedsätt­ning. Avsikten var dessutom att undersöka om elektrod­placering­ på örsnibb eller på mastoid påverkade mät­resultatet, försökspersonens upplevelse av instrumen­­t­ens ljudstimuli, om de estimerade ASSR-värdena påverkades av att mättillfället påbörjades eller avslutades med Interacoustics Eclipse samt undersöka tiden för mätningarna.En experimentell studie genomfördes. Mätningarna som utfördes var tonaudiometri och ASSR, den senare uppmättes med Interacoustics Eclipse och GSI Audera på (n=20) vuxna med normal hörsel och (n=4) vuxna med hörselnedsättning.För personer med normal hörsel påvisades en god överensstämmelse mellan estimerade ASSR-värden och tonaudiometri för Interacoustics Eclipse, något sämre överensstämmelse för GSI Audera. Genomsnittlig mättid för båda instrumenten var ca 40 min. Resultaten visade att elektrodplaceringen inte har någon påverkan på ASSR-värden för Interacoustics Eclipse.

Djurslagsskillnader vid användningen av opioidplåster till hund, katt och häst

Opioidplåster avsedda för humant bruk används idag även för smärtlindring av djur eftersom det inte finns några registrerade veterinärmediciniska opioidplåster. För humant bruk finns plåster innehållande fentanyl och buprenorfin. Syftet med litteraturstudien var att granska studier i farmakokinetik och dynamik för att undersöka den vetenskapliga grunden för användningen av opioidplåster till djurslagen hund, katt och häst. Plåster kan vara ett sätt att administrera läkemedel transdermalt till den systemiska cirkulationen. Avsikten med plåster är att uppnå jämna koncentrationer i plasma (Steady State) som varar under den tid som plåstret finns på plats, vanligen 72 h för människa. Vid användningen av fentanylplåster uppnåddes Steady State hos människa efter 14 h.

Meningen med livet och den liberala statens paradox

Liberal theorists typically argue that state action should not favor any particular conception of the good or meaningful life. On this view the defining characteristic of the liberal state is neutrality among rivaling ideas of the good. This thesis argues that state neutrality is impossible to maintain in practice. Two different versions of state neutrality; neutral justification and neutral aims, are used to analyze a wide range of political issues. It is concluded that far from being neutral, the liberal state favors individualistic and market oriented conceptions of the good life.

Hur viktig är statens styrka för ekonomiskt välstånd?- En studie av alla världens länder

What role does the state play in economic development? This thesis seeks to investigate the relationship between a strong state and economic development. To define the concept of a strong state I focus on the relationship between the scope of state functions and the efficiency of which these functions are implemented. The concept of a strong state is in this thesis defined as the efficiency of the state functions. By using a database constructed by three economists; David Kaufman, Aart Kraay and Massimo Mastruzzi as a measurement of a strong state I test the relationship with economic development empirically.

Civilsamhället i Ryssland : En fallstudie om hur den ryska staten förhåller sig till civilsamhället.

When Vladimir Putin in the year 2000 came to power in Russia many believed that the Russian civil society were weak and had very little influence and with Putin people say that the situation have deteriorated. The purpose of this paper is to establish what kind of relationship exists between the Russian state and the civil society and to analyze this from a top-down perspective. We are looking at Russia during Putins first term in office from the year 2000 until 2004. In order to establish the relationship we have used John S. Dryzeks theory of inclusive and exclusive state and whether it?s active or passive in this process.

Varierande Vägar till Frihet - Hur staten och civilsamhället interagerar för demokrati i Vitryssland, Moldavien och Ukraina

The three post-communist states - Belarus, Moldova, and Ukraine ? have gone different ways in terms of freedom and democracy since the breakdown of the Soviet Union 1991. During these years, the state and the civil society have been fundamental actors in the struggle against, and even for, authoritarianism.A strong state with great capacity in Belarus has undermined the chances for the civil society to fulfil its task as a watchdog of the state and link between the citizens and the government.Failed authoritarianism in Moldova has led to a situation where both the state and the civil society are weak. The major problem is lack of organization and cohesion; both the state and the civil society have often been divided by ethnical differences and are therefore not strong enough to promote democracy.In Ukraine, the dominance of a strong state ended in 2004 when the Orange Revolution took place, sometimes called a ?peak of democracy? where popular mobilization and protests succeeded in it's opposition against the state.

Statlig övervakning av Internet: En diskursanalys av riksdagstryck 1994-2007

This paper attempts to survey the debate in the Swedish parliament on state surveillance on the Internet, from 1994 to March, 2007. With a discourse analysis inspired by Foucault, we follow how the idea of state surveillance is viewed by politicians during the period. By focusing on the Internet, we expect to find how politicians in the parliament regard the idea of an unregulated forum for citizen communication and interaction, and how the need for state surveillance on the new arena that is Internet, is expressed and argued for. Theoretical framework is given by Foucault?s theory of the Panoptic state, as well as his thoughts on discourse, power and governmentality.

Autonomi och gemensamma strävanden

The liberal state, it has been argued, must be neutral between different conceptions of the good. Embodying ideals such as fairness and impartiality, state neutrality is intuitively appealing, but working as a restraint for state actions it is somewhat unsatisfactory. People make mistakes about their lives and people live less valuable lives than they could do. To then restrain the state from doing as much good as it can seems just as unappealing as neutrality at first seemed appealing. In this paper, a possible solution to this dilemma is presented.

Den försvinnande staten Tuvalu : En fallstudie om klimatflyktingars rättigheter och staters ansvar

This thesis aimed to, with the help of a case study, investigate and discuss state responsibility towards climate refugees. The state of Tuvalu was selected because of their vulnerability as a low-lying island state. This was fulfilled by on-site study how the state Tuvalu acted to climate threats, determine if the future migrants from Tuvalu can be counted as climate refugees and find out if they are by that definition included by the UN Refugee Convention. The result indicated that the state of Tuvalu is adapting to climate threats, that in the future the population can be seen as climate refugees, if they are forced from their homes due to climate change, and that they, despite that definition, can not be included by the UN Refugee Convention. The study also indicates a need for greater international protection of climate refugees by, for example, an expansion of the UN Refugee Convention so that these vulnerable people do not fall into oblivion due to a question of definition..

Automatisering av spraytorkningsprocess

ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a Steady State in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

?Det här är myndigheten med stort M ? en kvalitativ studie om skillnaderna mellan att arbeta som socialarbetare statligt respektive kommunalt?

This study is about state officials who handle applications for sickness benefits and about municipal officials who handle applications for financial assistance. The purpose of this study is to explore the differences between the two professional roles regarding their conception about their exercise of authority, in terms of flexibility, individual adjustment, empathy and legal security.The study has a qualitative approach and is based on structured interviews with two state officials and two municipal officials. The questions that this study aims to answer are:- Is there a difference between state officials and municipal officials regarding their experience and use of flexibility? - Is there a difference between state officials and municipal officials regarding their perceptions of legal security, individual adjustment and empathy in their exercise of authority? - What kind of bureaucracy can you find in the two organizations?The results show that the state officials in this study have very limited flexibility due to legislation which makes their exercise of authority neither empathic nor individual. The municipal officials in this study state in their turn that the law entails broad flexibility and the opportunity for them to be empathic and to make individual decisions.

Traditionella institutioner i Afrika - Ett hot mot den moderna staten?

The function of traditional leaders in the modern states of Africa has been under debate for decades. The dominant research discourse suggests that these institutions should be integrated into the state in order to minimize the amount of parallel political spheres, since the latters are considered to affect state legitimacy negatively. But are the states in a situation where they need to compete with the traditional institutions in order to gain more legitimacy? If so, is the struggle for legitimacy a zero-sum game where there can only be one winner? Or is it possible for these institutions to co-exist or even benefit from each other? The aim of this bachelor?s thesis is to research if, and to what extent, African citizens? confidence in traditional institutions has an effect on state legitimacy. This has been done by statistically analyzing the data from the latest completed round of the Afrobarometer survey, a study that has been conducted in 20 different countries across West- and Northeast Africa.
