Ranolazine: A New Option in the Management of Chronic Stable Angina
Authors: Dobesh Paul P. , Trujillo Toby C.
Published: November 2007

Pharmacotherapy for the management of chronic stable angina has not changed much in the past 10–20 years. Although the use of revascularization has increased, β‐blockers, calcium channel blockers, and long‐acting nitrates are still widely used in the management of patients with chronic stable angina. Despite the demonstrated effectiveness of these agents, a number of patients do not achieve the American College of Cardiology‐American Heart Association goal of freedom from exertional angina attacks. For the first time in more than a decade, a new agent, ranolazine, is available to assist in controlling exertional angina. Ranolazine has a novel mechanism of action of inhibiting the late sodium current during ventricular depolarization. This mechanism contributes to a reduction in intracellular sodium and, therefore, a reduction in intracellular calcium, reducing ischemic injury. Unlike currently available pharmacotherapy for chronic stable angina, ranolazine does not produce clinically meaningful changes in heart rate or blood pressure. A number of clinical trials have demonstrated the ability of ranolazine to increase exercise tolerance, decrease weekly anginal episodes, and decrease sublingual nitroglycerin consumption for breakthrough angina. Based on the results of these trials, ranolazine recently was approved by the United States Food and Drug Administration for treatment of patients with chronic stable angina. Because of ranolazine's pharmacokinetic and pharmacodynamic profile, pharmacists will have to play a significant role in patient selection and monitoring.
Some properties of Laplacian eigenvectors
Authors: Gutman Ivan
Published: November 2007

Let G be a graph on n vertices, G its complement and Kn the complete graph on n vertices. We show that if G is connected, then any Laplacian eigenvector of G is also a Laplacian eigenvector of G and of Kn . This result holds, with a slight modification, also for disconnected graphs. We establish also some other results, all showing that the structural information contained in the Laplacian eigenvectors is rather limited. An analogy between the theories of Laplacian and ordinary graph spectra is pointed out.

On duality theory and pseudodifferential techniques for Colombeau algebras: generalized delta functionals, kernels and wave front sets
Authors: Garetto Claudia , Hormann G.
Published: November 2007

Summarizing basic facts from abstract topological modules over Colombeau generalized complex numbers we discuss duality of Colombeau algebras. In particular, we focus on generalized delta functional and operator kernels as elements of dual spaces. A large class of examples is provided by pseudodifferential operators acting on Colombeau algebras. By a refinement of symbol calculus we review a new characterization of the wave front set for generalized functions with applications to microlocal analysis.

Inhomogeneous Gevrey ultradistributions and Cauchy problem
Authors: Calvo Daniela , Rodino L.
Published: November 2007

After a short survey on Gevrey functions and ultradistributions, we present the inhomogeneous Gevrey ultradistributions introduced recently by the authors in collaboration with A. Morando, cf. [7]. Their definition depends on a given weight function ?, satisfying suitable hypotheses, according to Liess-Rodino [16]. As an application, we define (s, ?)-hyperbolic partial differential operators with constant coefficients (for s > 1), and prove for them the well-posedness of the Cauchy problem in the frame of the corresponding inhomogeneous ultradistributions. This sets in the dual spaces a similar result of Calvo [4] in the inhomogeneous Gevrey classes, that in turn extends a previous result of Larsson [14] for weakly hyperbolic operators in standard homogeneous Gevrey classes.

Practical implications of 'postmodern philosophy'
Authors: Savic Mile
Published: November 2007

The article examines the implications of the discourse about postmodernity. Postmodernity is analyzed as a complex discursive figure. Within the discourse about postmodernity three levels are distinguished: the postmodern condition, postmodernism, and reflection of the postmodern condition. Special attention is paid to globalization and the problem of the enforcement of modern projects in East-European societies, particularly Serbia. These societies are termed object-societies, while their modification of modernity is called eastmodernity. The author's answer to the complexity of the postmodern condition is a conception of the politics of subsistence.
Nation state and the challenge of globalization: Project draft
Authors: Obrenovic Zoran
Published: November 2007

This project draft discusses the issues facing a nation state in the dynamic processes of globalization. First, the term globalization is tentatively defined as a decentralized process of condensation and homogenization of space and time. Then, the ambivalent structure of the globalization discourse, i.e. its semantic and pragmatic dimensions, are shown. The neo-liberal viewpoint is explored of the erosion and weakening of the nation state within the global capitalist power, both in terms of its (state's) traditional functions, and in terms of its internal and external sovereignty. Against the neo-liberal thesis about the decline of the nation state many empirical arguments have been offered. Some of these are presented in this text. The main point of this argumentation consists in a general view that the decline of the nation state is strongly linked with the process of globalization. In view of the critical argumentation included in the paper, it is argued that in the environment of global processes only the societies which have a strong state behind them have a chance to succeed. Politics, not economy, still dominates international relations. Emphasis on state politics opens a new perspective in discussing the process of globalization. Current globalization processes cannot be judged accurately unless geopolitical interests and the changing balance of world power are understood. Finally, the paper points to the ideological nature of the neo-liberal discourse of globalization, questioning another basic assumption of the latter, namely, the idea that the process of globalization is at the same time a process of emancipation. By challenging the positing of a necessary link between globalization and emancipation we formulate a position that allows for a normative critique of current processes.
Reexamining the "Serbian exceptionalism" thesis
Authors: Vujacic Veljko
Published: November 2007

Although former Yugoslavia constituted what was widely held to be the most "promising" communist country in terms of potentials for economic reform and political democratization, Serbia remained the only East European country in which the former communist elite managed to defeat its opponents in a series of elections and preserve important elements of institutional and ideological continuity with the old system. Moreover, its regime played a conspicuous role in Yugoslavia's violent collapse. In the specialist literature, the "Serbian exceptionalism" thesis has been elaborated in a number of forms. These are critically reviewed in the first part of the paper, classifying the paradigms according to whether they emphasize: 1) Serbian traditionalist, authoritarian, and collectivist political culture, 2) the affinity between traditional Serbian national populism, Russophile anti-Westernism, and communism, 3) the exclusivist and assimilating character of Serbian nationalism, or 4) the appeals of the contemporary Serbian political elite led by S. Milosevic. In the second part of the paper an alternative explanation is presented that seeks to be both interpretively adequate and causally plausible. It rests on five basic factors: 1) historical legacy (the distinctive character of the Serbian collective historical experience and the relationship between Serbian and Yugoslav identities); 2) institutional analysis (the unintended consequences of communist federalism); 3) ideology (the revival of narratives of "Serbian victimization" by Serbian intellectuals); 4) leadership and social base (the peculiar nature of Milosevic's appeals in the period of the terminal crisis of communism); and 5) the role of the Diaspora (the perceived ethnic threat among Serbs in Croatia and Bosnia). .
World order, globalization, and the question of sovereignty
Authors: Stupar Milorad
Published: November 2007

In light of world globalization, three visions of the world order have been examined. The naive cosmopolitanism has been examined first and then rejected as being unrealistic because it overlooks the reasons for state pluralism in the international order. On this naive view, the world state is the only source of sovereignty and the individual is the only focal point of moral concern. Second subject matter of our investigation were Kantian and Rawlsian views which still defend the state-centered view on international relations with peoples as a major subject of moral concern. However, on Rawls view, the principle of peoples' self-determination should be combined with the principles of universal morality which protect some individuals' fundamental rights thus enabling his theory to be classified into moderate liberal internationalism. Third, the idea of functional sovereignty as a foundation of the system of international sovereignty has been abandoned as being too unrealistic given recent tendencies in the world which associate the identities of individuals with cultures and civilizations rather than with practices and professions. Finally, some reasons have been given for preferring Rawlsian approach. The major reason is that there are close cultural ties between nations and their states and that this fact can contribute greatly to the resolution of coordination problem among states both internally and externally. .
Authoritarianism as an element of social character and a factor of gendered social interaction
Authors: Jovancevic Sasa
Published: November 2007

The immediacy of daily encounters with gender roles, as well as the specific features of authoritarian mediation in their social shaping, make an analysis of gendered social interaction indispensable. In this paper the analysis is centered on the concept of social character, with special emphasis on authoritarianism as a continuous determinant of the transformation of natural sex into social construct of gender. It is precisely the authoritarian personality type that is the basis for alienated gender, dominated by sexism, a ?natural? belonging to the private or the public sphere of social life, suppression of individual human capacities, and reduction of choice. After a review of the theoretical conceptions of social character and authoritarianism, a historical-comparative analysis of authoritarianism is offered, where the latter is seen as an element of the social character within the perspective of the typology traditional - modern - postmodern society. It is argued in conclusion that, in spite of certain emancipatory achievements, men and women still tend to escape into the security of authoritarian alienation. Feminist theory remains a basic source for reflecting on these processes; therefore the author pleads for a wider acceptance of feminist insights as contributions to establishing a postmodern, interpretive ?sociology in a new key?.
Schopenhauer and Wittgenstein: Assessing the Buddhist influences on their conceptions of ethics
Authors: Vukomanovic Milan
Published: November 2007

In the first part of this essay, the author discusses certain aspects of the Hindu and Buddhist philosophical and religious conceptions that could have made some impact on the European ethics before Schopenhauer. In the second part, he deals with various channels of possible Buddhist influence on Schopenhauer's ethical thought. Finally, in discussing Buddhist-Wittgenstein relationship, one is confronted with convergent, yet independent, responses to similar sets of problems. Independently, and less systematically than Buddhist philosophical schools, Wittgenstein indicates the way of liberation that cures from the "metaphysical pain " emerging from inappropriate use of language. His own project, however, was not metaphysical, but meta-linguistic in a very specific sense. The philosophical "cure" from the language disease leads ultimately to the "purification " and "decontamination " of thought: in turn, the mind rests in peace and silence before the senseless, paradoxical questions of the moral, esthetical religious or metaphysical character.
The sociologically acceptable definition of religion
Authors: Blagojevic Mirko
Published: November 2007

In this article the author has presented several important issues regarding the sociology of religion, but primarily the issue of the sociologically acceptable definition of religion both in theoretical and empirical research. Bearing in mind the sociology of religion in former Yugoslavia the author has first discussed the possibility of a general definition of the sociology of religion, but has stated the opposite view as well. Then he has dealt with the two basic approaches towards religion and two general definitions of sociology, namely substantial and functional ones. Finally the author has tried to define the religiousness in terms of sociological empirical research of human attachment to religion and church in post-socialism.

In the main part of the paper an analysis of liberalism and globalization has been offered. It has been argued in the third part of the paper that the process of association between Serbia and Montenegro and European Union would contribute substantially to the solution of the so called "coordination problem" in Serbia and Montenegro-the country heavily burdened and ravaged by its historical past, recent civil wars, NATO bombardment and corruptive economy.
Non-governmental organizations and politics of interpretation of South-Slavic’s recent past
Authors: Radojicic Mirjana
Published: November 2007

In the text the author considers politics of interpretation of South-Slavic peoples' recent past, which was demonstrated by the most prominent activists of Serbian non-governmental organizations. By summarizing the interpretation in a few points, the author attempts to identify its key features: arrogance and extremism as a style, counter factuality as a strategy and anti-Serbian nationalism and racism as an ideological strongpoint. In the final section of the text, what is pleaded is a precise legal regulation of that delicate area of civil activism, which in the last decade has presented a malignant protuberance on destroyed social tissue of Serbia and serious threat to the rest of its considerably lost national interests.

Current religious changes in Serbia and integration in Europe
Authors: Blagojevic Mirko
Published: November 2007

In the last decade and a half the process of desecularization has been undoubtedly verified in Serbia. Not only that the changes have been verified in the religious complex in general, but in traditional religious groups in particular as well. The revival of religiousness and people?s attachment to religion and church have been clearly proved in all aspects of religious life: in the areas of religious identification, doctrinaire religious beliefs and ritual religious practices. It should also be noted that in times of extremely turbulent political and social changes in the Balkans, all traditional religious complexes, orthodox, catholic and Muslim, began forming close ties with political and state, public and binding domains, which was absolutely unthinkable of a decade and a half ago. Which leads us to the crucial question: can religion make a contribution to the process of integration coming form the surrounding countries as the imperative of foreign powers on one hand, and as the striving of the majority of population in all the post socialist countries in the Balkans on the other hand, or will it only cause damage and interfere with the process of integration of those societies into the European commonwealth of nations? This article discusses different opinions that view the traditional complexes of religion, language and nation as disruptive factors of modernization of the Balkan countries, as well as completely opposite opinions based on the experiences of traditional Islamic societies in which religion is not a factor that hinders their rapid modernization.
To sleep, perchance to dream... or staying awake: On Balkanism and the failure of the constructivist standpoint in Serbia: A view from the past
Authors: Djeric Gordana
Published: November 2007

The paper examines the meanings of representations of Serbia, the Balkans and Europe at the time of encounter between Enlightenment and Romanticist traditions. The analysis starts from the assumption that the emergence of negative representations of South Eastern Europe cannot be discussed without placing it within the broader context of 18th and 19th century philosophy and literature and the consequences of new philosophical and literary ideas. Underlying the substantial change of the previously dominant paradigms that is expressed in the symbolic division into 'West' and "East', there was a factual rather than symbolic division into an industrial and an agricultural Europe, whose boundaries coincided with the reference points of the symbolic distinction. Insisting on the importance of both analytic levels - the 'symbolic' and the 'factual' - the first section of the paper briefly outlines the development of symbolic geography in the context of 'Balkan' studies ('Balkan variations of orientalism' or 'balkanism') in the 1990s, as well as the failure of this genre and the constructivist paradigm in Serbian social theory. The second section is devoted to the discourses of conceptualizing broader communities in symbolic, linguistic, imagological, cultural, political, economic etc. terms, focusing on the beginnings of ideological and linguistic unification of South Slavs and their inclusion into the "enlightened Europe". By analyzing Vuk Stefanovia: Karadzix's writings, as well as correspondence, articles and commentaries referring to Vuk's work in the first half of the 19th century, the author takes the perspective of the past in order to identify the reasons for the failure of imagological and constructivist approach today.

Bruno Latour, actor-networks, and the critique of critical sociology
Authors: Spasic Ivana
Published: November 2007

The paper analyzes the theoretical opus of Bruno Latour and his treatment of the concept of critique. In the first section "actor-network theory" is presented through its key notions (actant, network, translation, associations) together with Latour?s theory of modernity. In the second section various aspects of the relation between Latour and critique are discussed - first his own criticism of others (standard sociology and especially "critical", i.e. Bourdieu?s sociology), then the criticisms aimed at his work, to conclude with the political ambivalences of Latour?s attempt to develop an "acritical" social theory. .
Public reason as a political ideal: John Rawls’s conception
Authors: Pavicevic Djordje
Published: November 2007

The article dealt with Rawlsian idea of public reason as a convergence point of his conception of political liberalism. The idea of public reason is taken as a norm of political justification a as well as a political ideal. Major lines of criticism of the Rawls' conception are also discussed in the article. The conclusion is that is possible to defend major elements of Rawls' conception against criticism along Rawlsian lines of argumentation. The thesis advocated through the text is that it is significant legacy of Rawls' conception of public reason that it discloses limitations of political ideal of liberal democracy. It is argued that one important consequence is that liberalism has to disclaim its own moral superiority in order to make political ideal viable. The other is that any particular society has to find its moral bases in public reason of particular society, that is burdened with peculiar culture and history. .

Pleistocene horses (genus Equus) in the central Balkans
Authors: Forsten Ann , Dimitrijevic Vesna
Published: November 2007

A review of the fossil horses of the genus Equus from the central Balkans, a mountainous area comprising Serbia and Montenegro, is presented in this paper. The time period covered by the finds is from the late Early to and including the Late Pleistocene, but the record is not complete: the dated finds are Late Pleistocene in age, while Early and Middle Pleistocene are poorly represented. The horses found resemble those from neighbouring countries from the same time period, probably showing the importance of river valleys as migration routes. The Morava River valley runs in a roughly south-to-north direction, connecting, via the Danube and Tisa River valleys the Hungarian Pannonian Plain in the north with northern Greece in the south, via the Vardar River valley in Macedonia. In Pleistocene, large mammals, including horses, probably used this route for dispersal.
The Triassic metabasalts of Dudin Krs, near Kosovska Mitrovica, Serbia
Authors: Memovic Emin , Cvetkovic Vladica , Knezevic Vera , Zakariadze Guram
Published: November 2007

This paper presents the geochemical characteristics of the metabasalts of Dudin Krs, near Kosovska Mitrovica. The Dudin Krs is the easternmost occurrence of Middle Triassic rift-related volcanic rocks in the Dinarides. Generally, these rocks show similarities to other Triassic volcanic rocks of the Dinarides. They are high-magnesian, ol and ne-normative basalts, with low Zr/Nb and medium/low Ti/Zr and Ti/Y ratios. They exhibit transitional geochemical characteristics, between E-MORB and subalkaline basalts of continental rift zones. Their presence and geochemical affinity is evidence of rifting processes along the continental slope of the Adria block during Middle Triassic.
New dasycladales and microbiota from the lowermost Valanginian of the Mirdita zone
Authors: Radoicic Rajka
Published: November 2007

A rich diversified algal microbiota is described from the lowermost Valanginian limestone re?worked in the Upper Cretaceous elastics of the Metohija Cretaceous Unit (Mirdita Zone). Two new dasycladalean taxa are introduced: Zujovicella nov. gen. (type species Suppiluliumaella gocanini Radoicic, 1972) and Furcoporella vasilijesimici nov. sp. Microbiota of this bioclastic limestone (containing dominantly corals and other metazoan fragments) consists of algae, microbial epiliths, microproblematica, foraminifera, calcispongie and a few calpionellids of the Calpionellopsis Zone - Calpionellopsis oblonga (Cadisch), Remaniella cadischiana (Colom), Tinntinopsella carpathica (Murgeanu & Filipescu). Besides the new taxa dasycladales also associated are: Salpingoporella pygmaea (Gumbel), Salpingoporella sp., Gyroporella lukicae Sokac & Velic, Neomerinae and several indetermined taxa. Lithocodium aggregatum (Elliott), other encrusting Lithocodioidea and different microbial epiliths are an important component of this microbiota association. Foraminiferal assemblage consists of: Coscinophragma cf. C. cribrosum (Reuss), Mohlerina basiliensh (Mohler), Nautiloculina bronnimanni Arnaud-Vanneau & Peybernes, Neotrocholina valdensis Reichel, Neo-trocholina sp. Placopsilina sp., Protopeneroplis trochangulata Septfontaine, Trocholina alpina (Leupold), Trocholina delphinensis Arnaud-Vanneau, Boisseau & Darsac, Trocholina sp., lituolids, miliolids and other small benthic taxa. The analyzed lowermost Valanginian limestone originated from the topmost sequence of the Tithonian-Neocomian cycle which ended as a consequence of the Main Cimmerian Events, which occerred, as in the Vardar zone, after the lowermost Valanginian. Cretaceous cycle (Mirdita Crtaceous Unit) begins in the Hauterivian.

Unexpectedness and its pragmatic markers in standard serbian
Authors: Ivic Milka
Published: November 2007

The paper sets about to identify something researchers fail to consider: the principles that in Standard Serbian govern the occurrence of the pragmatic devices vec, jos, jos uvek, and vise (ne..) by means of which the speaker discloses that the information about an actual state of affairs he is giving to his conversation partner happens to be an unexpected news for him. It highlights also the informational effects of vec on somebody who is listening to the conversation between the speaker and the addressee but who does not share in all details their stock of knowledge about the conversational topic and it rises the relevant question of the theoretical status of such effects.

Experiments were conducted for solutions with different initial selenium concentration and different pH. The degree of conversion was determined as a function of time from the weight of the sediment, and can be described by Avrami-type equation of the following form: - ln ( 1 - ?) = (6.95 . 10 -3 . t )1.52 valid at constant temperature of 357 K for NaHSO3 reducer, rate constant k = 6.95.10-3 min-1, and t in minutes. When the reduction was carried out in SO2 stream, the rate constant k was found to be strongly dependent on the flow rate. Possible mechanism of the reduction process and the influence of the rate of the reduction on the morphology of the product were suggested.

Corrosion resistance of Cr - Ni (special steels) specimen is tested by electrochemical methods, numerical method of linear polarization and polarization resistance method in calcium-hypochlorite (Ca(OCl)2) solutions. With increasing of Ca(OCl)2 concentration, pH value of the solution increases, as well as active chlorine concentration and corrosion activity of the medium. According to the quantitative method of the corrosion resistance determination it can be concluded that the steels tested in 1 wt % Ca(OCl)2 solution are resistant, in 10 wt % solution constant, and in 50 wt % suspension less resistant. URANUS B6 showed the best corrosion resistance of all tested chromium - nickel steels in all tested corrosion mediums.
DTA and TGA study of MeSo4 (Me = Fe, Co, Ni) dissociation in the presence of coke
Authors: Boyanov B.S.
Published: November 2007

MeSO4 (Me = Fe, Co, Ni) dissociation is investigated in order to estimate the effect of temperature, time and presence of coke as reducer on the degree and mechanism of dissociation. It is proved that the presence of coke decreases the dissociation temperature considerably and increases the degree of MeSO4 dissociation. Based on the obtained experimental data, a mechanism of the processes is proposed. The obtained results can be used in the industrial production of non-ferrous metals for explaining the processes that take place in the reduction of zinc and lead cakes in order to achieve favorable environmental, technical and economic results.

Published: November 2007

The electrochemistry of Sn(II) was investigated with cyclic voltammetry and chronoamperometry in the 1-ethyl-3-methylimidazolium tetrafluoroborate molten salt containing free chloride ions (EMI ?BF4 ?Cl) originated from the mixture of EMIC and NaBF4 (60:40 mol%). The well defined redox waves for the electro deposition and dissolution of tin were observed on a platinum electrode at 303 K. The deposition of tin proceeded through a quasi-reversible step with two electron transfer, and the deposited tin was sufficiently recovered during oxidation. The experimental current-time transient coincided with the theory based on one-dimensional diffusion control.
Modern electrochemical processes and technologies in ionic melts
Authors: Omelchuk A. , Volkov S.V. , Zarubitskii O.G.
Published: November 2007

An analysis of the known methods for the electrochemical purification of non-ferrous metals in ionic melts is presented. A comparative estimation of the results of the electrochemical purification of non-ferrous metals by different methods has been performed. The main regularities of the electrochemical behavior of non-ferrous metals in conventional and electrode micro-spacing electrolysis are presented. It has been found that when electrolyzing some metals, e. g. bismuth, gallium, there is either no mass exchange between the electrodes, or it occurs under filtration conditions. It has been shown that the electrode micro-spacing processes provide a high quality of non-ferrous metals purification at low specific consumption of electric power and reagents. The use of bipolar electrodes and ?-alumina diaphragms hinders the transfer of metallic impurities from the anode to the cathode. The effects revealed were used to develop new processes for the separation of non-ferrous metal alloys in ionic melts; most of them have been put into practice in non-ferrous metallurgy.

Authors: Saltykova N.A.
Published: November 2007

The structure of platinum metals and their alloys deposited by the electrolysis of chloride melts have been investigated. The cathodic deposits were both in the form of compact layers and dendrites. All the alloys of platinum metals obtained are solid solutions in the whole range of composition. Depending on the experimental conditions the layers had columnar, stratum and spiral (dissipative) structures. The stratum and dissipative structures were observed in the case of alloys only.

The phase composition of cathodic deposits synthesized from FLINAK-K2TaF7-KBF4 melt has been studied by the X-ray diffraction method. It is shown that boron content in the electrodeposit grows as the cathodic potential is increased from peak R1 to peak R4 in the voltammogram. The scheme of changes in the phase composition depending on the increasing current density is given as follows: {?-Ta + Ta2B}R1 ? {?-Ta + (Ta3B4 TaB)}R2 ? {TaB2}R3 ? {TaB2 + B}R4.

Equilibrium electrochemical synthesis diagrams of systems, forming homogeneous alloys and compounds
Authors: Kaptay G.
Published: November 2007

In the present paper thermodynamic limitations will be derived and summarized in the form of Equilibrium Electrochemical Synthesis (EES) diagrams, in order to predict the composition of the equilibrium phase, synthesized by galvanostatic co-deposition of components on inert electrodes. As a thermodynamic parameter, a difference of deposition potentials of pure components ( ?E) on inert cathodes is used (this parameter is a function of melt composition and temperature). Generally, the EES diagram predicts the equilibrium composition of the alloy as function temperature and ?E. However, for systems with homogeneous alloy formation the composition- ?E diagrams, drawn at a fixed temperature are more informative. As examples EES diagrams are constructed for the liquid Mg-Nd alloy, for some A(III)-B(V) (where A = Al, Ga, In and B = As, Sb), Si-C and for the Al-Ti system. For the Al-rich part of the Al-Ti system, also a semi-schematic non-equilibrium ES diagram is constructed. Based on these diagrams, the synthesis conditions of various phases has been discussed.

Published: November 2007

The possibility of obtaining ? - anhydrite from nitrogypsum, which is waste from a nitrocellulose plant, was investigated. It was shown by means of qualitative IR analysis that the product obtained by heating nitrogypsum for 5 hours at 700 o C was ? - anhydrite. When the ?- anhydrite was mixed with water at a W/S (water/solid) ratio of 0.54 in presence of different accelerators (CaO, mixture CaO - ash, ash, Na2SO4 and K2SO4), pastes were formed which hardened on standing. The compressive strength of the hardened samples was measured after 7 and 28 days and their composition determined by qualitative IR analysis. On the basis of these results, it was observed that a relationship exists between the composition (depending on the used accelerator) and the compression strength of the samples. Namely, the formation of large cores of double salts: syngenite (K2SO4 ?CaSO4 ?H2O) and glauberite (Na2SO4 ?CaSO4), in the presence of the accelerators K2SO4 and Na2SO4, respectively, was due to the rapid and complete crystallization of the dihydrate (CaSO4 ?2H2O). This fast crystal growth of the dihydrate resulted in high compressive strengths of these samples. In the other samples (prepared in presence of the accelerators: CaO, mixture CaO - ash and ash), dihydrate did not form and, consequently, their compressive strength was low.

Published: November 2007

Samples of copper-based alloys, Cu-4at%Zn, Cu-8at%Zn and Cu-5at%Ni-2at%Sn and pure copper have been prepared by a powder metallurgical method. The samples were subjected to cold rolling to 30, 50 and 70% in reduction, followed by annealing up to the recrystallization temperatures. Anneal hardening effect has been observed with the alloys in an annealing temperature range of 180-4000C, the hardness being increased with the amount of reduction at the prior cold - rolling.
Selection of crucible oxides in molten titanium and titanium aluminum alloys by thermo-chemistry calculations
Authors: Kostov A. , Friedrich B.
Published: November 2007

Titanium and its alloys interstitially dissolve a large amount of impurities such as oxygen and nitrogen, which degrade the mechanical and physical properties of alloys. On the other hand crucible oxides based on CaO, ZrO2 Y2O3, etc., and their spinels (combination of two or more oxides) can be used for melting titanium and its alloys. However, the thermodynamic behavior of calcium, zirconium, yttrium on the one side, and oxygen on the other side, in molten Ti and Ti-Al alloys have not been made clear and because of that, it is very interesting for research. Owing of literature data, as well as these crucibles are cheaper than standard crucibles for melting titanium and titanium alloys, in this paper will be presented the results of selection of thermo-chemistry analysis with the aim to determine the crucible oxide stability in contact with molten titanium and titanium-aluminum alloys.
