The Impact of Emissions Trading on the Price of Electricity in Nord Pool : Market Power and Price Determination in the Nordic Electricity Market

The objective of this thesis is to find out how dominant firms in a liberalised electricity market will react when they face an increase in the level of costs due to emissions trading, and how this will effect the price of electricity. The Nordic electricity market is chosen as the setting in which to examine the question, since recent studies on the subject suggest that interaction between electricity markets and emissions trading is very much dependent on conditions specific to each market area. There is reason to believe that imperfect competition prevails in the Nordic market, thus the issue is approached through the theory of oligopolistic competition. The generation capacity available at the market, marginal cost of electricity production and seasonal levels of demand form the data based on which the dominant firms are modelled using the Cournot model of competition. The calculations are made for two levels of demand, high and low, and with several values of demand elasticity. The producers are first modelled under no carbon costs and then by adding the cost of carbon dioxide at 20€/t to those technologies subject to carbon regulation. In all cases the situation under perfect competition is determined as a comparison point for the results of the Cournot game. The results imply that the potential for market power does exist on the Nordic market, but the possibility for exercising market power depends on the demand level. In season of high demand the dominant firms may raise the price significantly above competitive levels, and the situation is aggravated when the cost of carbon dioixide is accounted for. Under low demand leves there is no difference between perfect and imperfect competition. The results are highly dependent on the price elasticity of demand.

Informational efficiency of the European Union emission allowance market

This thesis studies the informational efficiency of the European Union emission allowance (EUA) market. In an efficient market, the market price is unpredictable and profits above average are impossible in the long run. The main research problem is does the EUA price follow a random walk. The method is an econometric analysis of the price series, which includes an autocorrelation coefficient test and a variance ratio test. The results reveal that the price series is autocorrelated and therefore a nonrandom walk. In order to find out the extent of predictability, the price series is modelled with an autoregressive model. The conclusion is that the EUA price is autocorrelated only to a small degree and that the predictability cannot be used to make extra profits. The EUA market is therefore considered informationally efficient, although the price series does not fulfill the requirements of a random walk. A market review supports the conclusion, but it is clear that the maturing of the market is still in process.

Efficient Content-based Routing, Mobility-aware Topologies, and Temporal Subspace Matching

Event-based systems are seen as good candidates for supporting distributed applications in dynamic and ubiquitous environments because they support decoupled and asynchronous many-to-many information dissemination. Event systems are widely used, because asynchronous messaging provides a flexible alternative to RPC (Remote Procedure Call). They are typically implemented using an overlay network of routers. A content-based router forwards event messages based on filters that are installed by subscribers and other routers. The filters are organized into a routing table in order to forward incoming events to proper subscribers and neighbouring routers. This thesis addresses the optimization of content-based routing tables organized using the covering relation and presents novel data structures and configurations for improving local and distributed operation. Data structures are needed for organizing filters into a routing table that supports efficient matching and runtime operation. We present novel results on dynamic filter merging and the integration of filter merging with content-based routing tables. In addition, the thesis examines the cost of client mobility using different protocols and routing topologies. We also present a new matching technique called temporal subspace matching. The technique combines two new features. The first feature, temporal operation, supports notifications, or content profiles, that persist in time. The second feature, subspace matching, allows more expressive semantics, because notifications may contain intervals and be defined as subspaces of the content space. We also present an application of temporal subspace matching pertaining to metadata-based continuous collection and object tracking.

Posted Workers and Free Movement of Services in the European Union – the Impact on National Employment and Immigration Law

This thesis examines posting of workers within the free movement of services in the European Union. The emphasis is on the case law of the European Court of Justice and in the role it has played in the liberalisation of the service sector in respect of posting of workers. The case law is examined from two different viewpoints: firstly, that of employment law and secondly, immigration law. The aim is to find out how active a role the Court has taken with regard these two fields of law and what are the implications of the Court’s judgments for the regulation on a national level. The first part of the thesis provides a general review of the Community law principles governing the freedom to provide services in the EU. The second part presents the Posted Workers’ Directive and the case law of the European Court of Justice before and after the enactment of the Directive from the viewpoint of employment law. Special attention is paid to a recent judgment in which the Court has taken a restrictive position with regard to a trade union’s right to take collective action against a service provider established in another Member State. The third part of the thesis concentrates, firstly, on the legal status of non-EU nationals lawfully resident in the EU. Secondly, it looks into the question of how the Court’s case law has affected the possibilities to use non-EU nationals as posted workers within the freedom to provide services. The final chapter includes a critical analysis of the Court’s case law on posted workers. The judgments of the European Court of Justice are the principal source of law for this thesis. In the primary legislation the focus is on Articles 49 EC and 50 EC that lay down the rules concerning the free movement of services. Within the secondary legislation, the present work principally concentrates on the Posted Workers’ Directive. It also examines proposals of the European Commission and directives that have been adopted in the field of immigration. The conclusions of the case study are twofold: while in the field of employment law, the European Court of Justice has based its judgments on a very literal interpretation of the Posted Workers’ Directive, in the field of immigration its conclusions have been much more innovative. In both fields of regulation the Court’s judgments have far-reaching implications for the rules concerning posting of workers leaving very little discretion for the Member States’ authorities.

Cryptographic Software Export Controls in the EU

Certain software products employing digital techniques for encryption of data are subject to export controls in the EU Member States pursuant to Community law and relevant laws in the Member States. These controls are agreed globally in the framework of the so-called Wassenaar Arrangement. Wassenaar is an informal non-proliferation regime aimed at promoting international stability and responsibility in transfers of strategic (dual-use) products and technology. This thesis covers provisions of Wassenaar, Community export control laws and export control laws of Finland, Sweden, Germany, France and United Kingdom. This thesis consists of five chapters. The first chapter discusses the ratio of export control laws and the impact they have on global trade. The ratio is originally defence-related - in general to prevent potential adversaries of participating States from having the same tools, and in particular in the case of cryptographic software to enable signals intelligence efforts. Increasingly as the use of cryptography in a civilian context has mushroomed, export restrictions can have negative effects on civilian trade. Information security solutions may also be took weak because of export restrictions on cryptography. The second chapter covers the OECD's Cryptography Policy, which had a significant effect on its member nations' national cryptography policies and legislation. The OECD is a significant organization,because it acts as a meeting forum for most important industrialized nations. The third chapter covers the Wassenaar Arrangement. The Arrangement is covered from the viewpoint of international law and politics. The Wassenaar control list provisions affecting cryptographic software transfers are also covered in detail. Control lists in the EU and in Member States are usually directly copied from Wassenaar control lists. Controls agreed in its framework set only a minimum level for participating States. However, Wassenaar countries can adopt stricter controls. The fourth chapter covers Community export control law. Export controls are viewed in Community law as falling within the domain of Common Commercial Policy pursuant to Article 133 of the EC Treaty. Therefore the Community has exclusive competence in export matters, save where a national measure is authorized by the Community or falls under foreign or security policy derogations established in Community law. The Member States still have a considerable amount of power in the domain of Common Foreign and Security Policy. They are able to maintain national export controls because export control laws are not fully harmonized. This can also have possible detrimental effects on the functioning of internal market and common export policies. In 1995 the EU adopted Dual-Use Regulation 3381/94/EC, which sets common rules for exports in Member States. Provisions of this regulation receive detailed coverage in this chapter. The fifth chapter covers national legislation and export authorization practices in five different Member States - in Finland, Sweden, Germany, France and in United Kingdom. Export control laws of those Member States are covered when the national laws differ from the uniform approach of the Community's acquis communautaire.

Rwanda Crisis and Genocide in Case Law of Rwanda Tribunal

After the Second World War the public was shocked to learn about the horrors perpetrated. As a response to the Holocaust, the newly established United Nations adopted the Genocide Convention of 1948 to prevent future genocides and to punish the perpetrators. The Convention remained, however, almost dead letter until the present day. In 1994, the long-lasted tension between the major groups of Hutu and Tutsi in Rwanda erupted in mass scale violence towards the Tutsi ethnic group. The purpose was to eradicate the Tutsi population of Rwanda. The international community did not halt the genocide. It stood by idle, failing to follow the swearing-in of the past. The United Nations established the International Criminal Tribunal for Rwanda (the ICTR) to bring to justice persons responsible for the genocide. Ever since its creation the ICTR has delivered a wealth of judgements elucidating the legal ingredients of the crime of genocide. The case law on determining the membership of national, ethnic, racial or religious groups has gradually shifted from the objective to subjective position. The membership of a group is seen as a subjective rather than objective concept. However, a totally subjective approach is not accepted. Therefore, it is necessary to determine some objective existence of a group. The provision on the underlying offences is not so difficult to interpret compared to the corresponding one on the protected groups and the mental element of genocide. The case law examined, e.g., whether there is any difference between the words killing and meurtre, the nature of mental harm caused by the perpetrator and sexual violence in the conflict. The mental element of genocide or dolus specialis of genocide is not thoroughly examined in the case law of the ICTR. In this regard, reference in made, in addition, to the case law of the other ad hoc Tribunal. The ICTR has made a significant contribution to the law of genocide and international criminal justice in general. The corpus of procedural and substantive law constitutes a basis for subsequent trials in international and hybrid tribunals. For national jurisdictions the jurisprudence on substantive law is useful while prosecuting international crimes.

Monopolising Names? : The Protection of Geographical Indications in the European Community

Marketing of goods under geographical names has always been common. Aims to prevent abuse have given rise to separate forms of legal protection for geographical indications (GIs) both nationally and internationally. The European Community (EC) has also gradually enacted its own legal regime to protect geographical indications. The legal protection of GIs has traditionally been based on the idea that geographical origin endows a product exclusive qualities and characteristics. In today s world we are able to replicate almost any prod-uct anywhere, including its qualities and characteristics. One would think that this would preclude protec-tion from most geographical names, yet the number of geographical indications seems to be rising. GIs are no longer what they used to be. In the EC it is no longer required that a product is endowed exclusive characteristics by its geographical origin as long as consumers associate the product with a certain geo-graphical origin. This departure from the traditional protection of GIs is based on the premise that a geographical name extends beyond and exists apart from the product and therefore deserves protection itself. The thesis tries to clearly articulate the underlying reasons, justifications, principles and policies behind the protection of GIs in the EC and then scrutinise the scope and shape of the GI system in the light of its own justifications. The essential questions it attempts to aswer are (1) What is the basis and criteria for granting GI rights? (2) What is the scope of protection afforded to GIs? and (3) Are these both justified in the light of the functions and policies underlying granting and protecting of GIs? Despite the differences, the actual functions of GIs are in many ways identical to those of trade marks. Geographical indications have a limited role as source and quality indicators in allowing consumers to make informed and efficient choices in the market place. In the EC this role is undermined by allowing able room and discretion for uses that are arbitrary. Nevertheless, generic GIs are unable to play this role. The traditional basis for justifying legal protection seems implausible in most case. Qualities and charac-teristics are more likely to be related to transportable skill and manufacturing methods than the actual geographical location of production. Geographical indications are also incapable of protecting culture from market-induced changes. Protection against genericness, against any misuse, imitation and evocation as well as against exploiting the reputation of a GI seem to be there to protect the GI itself. Expanding or strengthening the already existing GI protection or using it to protect generic GIs cannot be justified with arguments on terroir or culture. The conclusion of the writer is that GIs themselves merit protection only in extremely rare cases and usually only the source and origin function of GIs should be protected. The approach should not be any different from one taken in trade mark law. GI protection should not be used as a means to mo-nopolise names. At the end of the day, the scope of GI protection is nevertheless a policy issue.

The Road to Hell Is Paved with Good Interventions : A Pragmatic Examination of Humanitarian Intervention with Special Reference to Kosovo

Kansainvälisen oikeuden alaan kuuluvassa tutkielmassa käsitellään humanitaarisen intervention oikeutusta ja laillisuutta. Tutkimuskysymyksenä on, missä määrin humanitaarisilla näkökohdilla perusteltuja sotilaallisia toimia tai niillä uhkaamista voi pitää kansainvälisoikeudellisesti hyväksyttävänä ja millainen painoarvo ennakkotapauksena olisi annettava NATO-maiden Kosovossa toteuttamalle väliintulolle. Tutkielmassa perehdytään ihmisoikeusajattelun tiettyjen taustaoletusten kritiikkiin. Tarkastelun kohteena ovat erityisesti kannanotot, joiden mukaan ihmisoikeuksia ei voi pitää luonteeltaan universaaleina, sekä kyseiseen kritiikkiin liittyvät väitteet siitä, että ns. hegemonisessa asemassa olevat valtiot hyödyntävät ihmisoikeusargumentteja oikeuttaakseen voimankäyttönsä. Universaalisuuskritiikkiä voidaan pitää pitkälti perusteltuna, mutta nykyinen kansainvälinen yhteisö tarvitsee kuitenkin tietynlaisia yleismaailmallisia normeja voidakseen toimia tehokkaasti. Kritiikin ei voikaan katsoa pätevän humanitaarisen intervention kannalta keskeisiin ihmisoikeusnormeihin kuten kansanmurhan kieltoon, sillä kyseiset velvoitteet suojaavat kansainvälisen yhteisön toimivuutta ja uskottavuutta. Humanitaarisiin argumentteihin liittyy kuitenkin muita ongelmia: niillä on esimerkiksi aika ajoin pyritty oikeuttamaan sotilaallisia toimia, joissa ihmisoikeusnäkökohdat eivät välttämättä ole olleet etusijalla. Ihmisoikeuksille ei ole syytä antaa kansainvälisessä oikeudessa asemaa universaaleina "superargumentteina", jotka eivät olisi kyseenalaistettavissa. YK:n peruskirjan ja kansainvälisen tapaoikeuden näkökulmasta humanitaarisen intervention kaltaiseen voimankäyttöön vaaditaan turvallisuusneuvoston hyväksyntä, jota ei Kosovo-operaatioon saatu. Interventiota voi tässä suhteessa pitää yksiselitteisesti laittomana, sillä sen tueksi esitetyt oikeudelliset argumentit eivät ole vakuuttavia. Tapaukseen liittyvät ihmisoikeusnäkökohdat ovat kuitenkin siinä määrin merkittäviä, että ongelmaan ei ole perusteltua suhtautua tiukan legalistisesti. Operaation hyväksyminen moraaliargumenttien nojalla voisi kuitenkin johtaa nykyisten voimankäyttörajoitusten marginalisoitumiseen, mikä olisi yllä käsitellyn kritiikin valossa ongelmallista. Tutkielmassa nostetaan suositeltavaksi ratkaisuksi lähestymistapa, jossa Kosovon tapaus ymmärretään yksittäisenä oikeudenvastaisena mutta samalla oikeudenulkoisena poikkeustapauksena. Tällöin peruskirjan mukainen voimankäytön sääntely säilyy entisellään ilman että humanitaariset näkökohdat jäisivät tyystin huomiotta. Ratkaisu ei sulje pois mahdollisuutta suhtautua positiivisesti Kosovo-operaation mahdollisesti luomaan "poliittiseen normiin": suuren mittakaavan ihmisoikeusloukkaukset eivät jää Euroopassa seurauksitta. Ilman turvallisuusneuvoston suostumusta toteutettaviin humanitaarisiin interventioihin liittyvien käytännöllisten ja kansainvälisoikeudellisten riskien vuoksi niihin on kuitenkin aihetta suhtautua suurella varauksella.

From Francovich to Köbler and beyond : The evolution of a State liability regime for the EC

The aim of this paper is to present the evolution of the Francovich doctrine within the European legal order. The first part deals with the gradual development of the ECJ's case law on State liability in damages for breach of EC law. Starting from the seminal Francovich and Brasserie du Pêcheur, the clarification of the criteria set by the Court is attempted with reference to subsequent case law, whereas issues concerning the extent and form of the compensation owned are also mentioned. The second part concerns one of the more recent developments in the field, namely State liability for breaches of Community law attributed to national judiciary. The Court's ruling in Köbler is examined in connection with two other recent judgments, namely Commission v. Italy of 2003 and Kühne & Heitz, as an attempt of the ECJ to reframe its relationships with national supreme courts and appropriate for itself the position of the Supreme Court in the European legal order. The implications on State liability claims by the ruling in Commission v. France of 1997 constitute the theme of the third part, where it is submitted that Member States can also be held liable for disregard of Community law by private individuals within their respected territories. To this extent, Schmidberger is viewed as a manifestation of this opinion, with fundamental rights acquiring a new dimension, being invoked by the States, contra the individuals as a shield to liability claims. Finally, the third part examines the relationship between the Francovich doctrine and the principle of legal certainty and concludes that the solutions employed by the ECJ have been both predictable and acceptable by the national legal orders. Keywords: State liability, damages, Francovich, Köbler, Schmidberger

Aspects of Arminian Soteriology in Methodist-Lutheran Ecumenical Dialogues in 20th and 21st Century

The aim of this thesis is to analyse the key ecumenical dialogues between Methodists and Lutherans from the perspective of Arminian soteriology and Methodist theology in general. The primary research question is defined as: "To what extent do the dialogues under analysis relate to Arminian soteriology?" By seeking an answer to this question, new knowledge is sought on the current soteriological position of the Methodist-Lutheran dialogues, the contemporary Methodist theology and the commonalities between the Lutheran and Arminian understanding of soteriology. This way the soteriological picture of the Methodist-Lutheran discussions is clarified. The dialogues under analysis were selected on the basis of versatility. Firstly, the sole world organisation level dialogue was chosen: The Church – Community of Grace. Additionally, the document World Methodist Council and the Joint Declaration on the Doctrine of Justification is analysed as a supporting document. Secondly, a document concerning the discussions between two main-line churches in the United States of America was selected: Confessing Our Faith Together. Thirdly, two dialogues between non-main-line Methodist churches and main-line Lutheran national churches in Europe were chosen: Fellowship of Grace from Norway and Kristuksesta osalliset from Finland. The theoretical approach to the research conducted in this thesis is systematic analysis. The Remonstrant articles of Arminian soteriology are utilised as an analysis tool to examine the soteriological positions of the dialogues. New knowledge is sought by analysing the stances of the dialogues concerning the doctrines of partial depravity, conditional election, universal atonement, resistible grace and conditional perseverance of saints. This way information is also provided for approaching the Calvinist-Arminian controversy from new perspectives. The results of this thesis show that the current soteriological position of the Methodist-Lutheran dialogues is closer to Arminianism than Calvinism. The dialogues relate to Arminian soteriology especially concerning the doctrines of universal atonement, resistible grace and conditional perseverance of saints. The commonalities between the Lutheran and Arminian understanding of soteriology exist mainly in these three doctrines as they are uniformly favoured in the dialogues. The most discussed area of soteriology is human depravity, in which the largest diversity of stances occurs as well. On the other hand, divine election is the least discussed topic. The overall perspective, which the results of the analysis provide, indicates that the Lutherans could approach the Calvinist churches together with the Methodists with a wider theological perspective and understanding when the soteriological issues are considered as principal. Human depravity is discovered as the area of soteriology which requires most work in future ecumenical dialogues. However, the detected Lutheran hybrid notion on depravity (a Calvinist-Arminian mixture) appears to provide a useful new perspective for Calvinist-Arminian ecumenism and offers potentially fruitful considerations to future ecumenical dialogues.

A Soul for Europe? : Contributions of European Churches to the Forum of the Convention on the Future of Europe

The aim of this research was to study how European churches contributed to the shaping of the Constitutional Treaty during the work of the Convention on the future of Europe through the public discussion forum, established by the Convention for this specific purpose in the years 2002 2003. In particular, this study sought to uncover the areas of interest brought up by the churches in their contributions, the objectives they pursued, and the approaches and arguments they employed to reach those objectives. The data for this study comprised all official submissions by European churches and church alliances to the Forum, totalling 21 contributions. A central criterion for inclusion of the data was that the organization can reasonably be assumed to represent the official position of one or more Christian churches within the European Union before the 2004 expansion. The contributing churches and organizations represent the vast majority of Christians in Europe. The data was analyzed using primarily qualitative content analysis. The research approach was a combination of abductive and inductive inference. Based on the analysis a two-fold theoretical framework was adopted, focusing on theories of public religion, secularization and deprivatization of religion, and of legitimation and collective identity. The main areas of interest found in the contributions of the churches were the value foundation of the European Union, which is demanded to coherently permeate all policies and actions of the EU, and the social dimension of Europe, which must be given equal status to the political and economic dimensions. In both areas the churches claim significant experience and expertise, which they want to see recognized in the Constituional Treaty through a formally guaranteed status for churches and religious communities in the EU. In their contributions the churches show a strong determination to secure a significant role for both religion and religious communities in the public life of Europe. As for the role of religion, they point out to its potential as a motivating and cohesive force in society and as a building block for a collective European identity, which is still missing. Churches also pursue a substantial public role for themselves beyond the spiritual dimension, permeating the secular areas of the social, political and economic dimensions. The arguments in suppport of such role are embedded in their interest and expertise in spiritual and other fundamental values and their broad involvement in providing social services. In this context churches use expressions inclusive of all religions and convictions, albeit clearly advocating the primacy of Europe's Christian heritage. Based on their historical role, their social involvement and their spiritual mission they use the public debate on the Constitutional Treaty to gain formal legitimacy for the public status of religion and religious communities, both nationally and on a European level, through appropriate provisions in the constitutional text. In return they offer the European Union ways of improving its own legitimacy by reducing the democratic and ideological deficit of the EU and advancing the development a collective European identity.

The church must become the people of Soweto : Manas Buthelezi’s existential-Christocentric understanding of the church

The aim of this study has been to discern what Manas Buthelezi (1935-), a black South African Lutheran theologian and later also a bishop, regards as the requirements a church has to fulfill in order to be credible in the apartheid society. Buthelezi’s dissertation and several articles written between the years 1968 and 1993 are the sources of this study. Also the lectures held in Heidelberg in 1972 are referred to. Systematic analysis is the method used. The question of the credibility of the church is studied through three concepts that play an important role in Buthelezi’s ecclesiological thought, namely the wholeness of life, incarnation and liberation. The notion of the wholeness of life stems from the African tradition. Buthelezi takes the concept into the Christian church: the church should realize that God is the Creator of all life and Christ the lord of every aspect of human existence. Life is one entity coram Deo. However, the church is not to become the world; solidarity between the two must remain critical as the church is also called to play a prophetic role in the society. The church is in an open relationship with the world. It has a unique message of forgiveness and reconciliation. Nevertheless, the message is not a possession of the church but it is addressed to the whole world. The meaning of incarnation comes close to that of the wholeness of life. Following the example of Christ’s incarnation, the church must become human in the reality of the people. The church in Soweto is to become the people of Soweto, that is, the church must become as vulnerable as the people are. An incarnate church cannot be immune to the oppression that people experience, because the people are the church. The church is therefore bound to suffer. Buthelezi’s theology of the cross is pragmatic: the suffering of the church aims at the liberation of the oppressed. At times the physical presence of the church by the side of the suffering people is the only way to preach the incarnate gospel. In the South Africa of the late 1960s onwards the liberation of the oppressed black people was high on the agenda of Black Theology. As a leader of the early South African Black Theology, Buthelezi is concerned about the racial injustice in his country. He urges the churches to join the struggle against it as one people of God. The notions of liberation and the wholeness of life emerge in Buthelezi’s holistic understanding of liberation that involves the inner liberation of the black spirit and the liberation of the economic, social and political aspects of life. Interpreting Tillich’s correlation method in the South African situation, and also paralleling other liberation theologians, Buthelezi takes the existential situation of the people as the starting point for liberation. The gospel has to respond to the existential questions of people. The church is called to work for the liberation of society but it must also be liberated itself. Buthelezi initiated the LWF statement on the status confessionis in South Africa (1977). In line with the statement, he calls for church unity on the human level. For the unity to be true, it has to be experienced on the grassroots’ level. All the three concepts covered urge the church to come down from any ivory tower and out of any spiritual haven it might hide in. A lot of the credibility of the church derives from the behavior of the people. Buthelezi’s concentration on how the people who constitute the church should live their faith leaves less attention to how God constitutes the church. I have labeled Buthelezi’s understanding of the church existential-Christocentric due to the emphasis he lays on the need of the church to take the existential situation of the people seriously and on the other hand, on Christ as the exemplar for the church.

Theoretical Studies on Coupled Electron and Proton Transfer in Cytochrome c Oxidase

The complexity of life is based on an effective energy transduction machinery, which has evolved during the last 3.5 billion years. In aerobic life, the utilization of the high oxidizing potential of molecular oxygen powers this machinery. Oxygen is safely reduced by a membrane bound enzyme, cytochrome c oxidase (CcO), to produce an electrochemical proton gradient over the mitochondrial or bacterial membrane. This gradient is used for energy-requiring reactions such as synthesis of ATP by F0F1-ATPase and active transport. In this thesis, the molecular mechanism by which CcO couples the oxygen reduction chemistry to proton-pumping has been studied by theoretical computer simulations. By building both classical and quantum mechanical model systems based on the X-ray structure of CcO from Bos taurus, the dynamics and energetics of the system were studied in different intermediate states of the enzyme. As a result of this work, a mechanism was suggested by which CcO can prevent protons from leaking backwards in proton-pumping. The use and activation of two proton conducting channels were also enlightened together with a mechanism by which CcO sorts the chemical protons from pumped protons. The latter problem is referred to as the gating mechanism of CcO, and has remained a challenge in the bioenergetics field for more than three decades. Furthermore, a new method for deriving charge parameters for classical simulations of complex metalloenzymes was developed.
