Anodisation Process

Plasma anodisation is an attractive technique for growing insulating layers of SiO2 at much lower temperatures then those needed for thermal oxide growth. Defects can be generated in silicon when it is subjected to prolonged high temperature oxidation processes, which in turn lead to degradation in both yield and performance of small geometry devices. An additional disadvantage of thermal oxide growth lies in the lateral oxidation behaviour (i.e. oxidation underneath the mask or ‘bird-beaking’ effect) which limits the minimum device separation which can be achieved. Although plasma anodisation has been widely investigated (see and references therein), previous studies have highlighted the severe difficulty of producing effective masks for this process, particularly during the high power anodisation studies which are the subject of this paper. Most of the established masks against thermal oxidation appear to be consumed during the plasma anodisation process. Therefore an important issue with regard to plasma anodisation is to find material systems in which the vertical oxidation rate of the mask is low compared to silicon and the lateral oxidation of both the mask and the silicon substrate under the mask are minimal. For the present study, two materials systems have been investigated; Si3N4/SiO2 strips on Si and Al/SiO2 strips on Si.

Special Meaning

A special role in the development of a pianist as a musician, composer and performer, as shown by the examples of the well-known, included in the history of art, and the most ordinary pianists, their listeners and admirers, lovers of piano music and music in general, are played by moments associated with psychotherapeutic abilities and music features. The purpose of the study is to comprehend the psychotherapeutic aspects of performing activities (using pianists as an example). The research method is a theoretical analysis of the psychotherapeutic aspects of performing activities: the study of the possibilities and functions of musical psychotherapy in the life of a musician as a “(self) psychotherapist” and “patient”. For almost any person, music acts as a way of self-understanding and understanding of the world, a way of self-realization, rethinking and overcoming life's difficulties - internal and external "blockages" of development, a way of saturating life with universal meanings, including a person in the richness of his native culture and universal culture as a whole. Art and, above all, its metaphorical nature help to bring out and realize internal experiences, provide an opportunity to look at one’s own experiences, problems and injuries from another perspective, to see a different meaning in them. In essence, we are talking about art therapy, including the art of writing and performing music - musical psychotherapy. However, for a musician, music has a special meaning, special significance. Musician - produces music, and, therefore, is not only an “object”, but also the subject of musical psychotherapy. The musician’s training includes preparing him as an individual and as a professional to perform functions that can be called psychotherapeutic: in the works of the most famous performers, as well as in the work of ordinary teachers, psychotherapeutic moments sometimes become key. Piano music and performance practice sets a certain “viewing angle” of life, and, in the case of traumatic experiences, a new way of understanding a difficult, traumatic and continuing to excite a person event, changing his attitude towards him. It helps to see something that was hidden in the hustle and bustle of everyday life or in the patterns of relationships familiar to a given culture. At the same time, while playing music or learning to play music, a person teaches to see the hidden and understand the many secrets of the human soul, the relationships of people.

Al Composite

The nucleation and growth mechanisms during high temperature oxidation of liquid Al−3% Mg and Al−3% Mg−3% Si alloys were studied with the aim of enhancing our understanding of a new composite fabrication process. The typical oxidation sequence consists of an initial event of rapid but brief oxidation, followed by an incubation period of limited oxide growth after which bulk Al2O3/Al composite forms. A duplex oxide layer, MgO (upper) and MgAl2O4 (lower), forms on the alloy surface during initial oxidation and incubation. The spinel layer remains next to the liquid alloy during bulk oxide growth and is the eventual repository for most of the magnesium in the original alloy. Metal microchannels developed during incubation continuously supply alloy through the composite to the reaction interface. During the growth process, a layered structure exists at the upper extremity of the composite, consisting of MgO at the top surface, MgAl2O4 (probably discontinuous), Al alloy, and finally the bulk Al2O3 composite containing microchannels of the alloy. The bulk oxide growth mechanism appears to involve continuous formation and dissolution of the Mg-rich oxides at the surface, diffusion of oxygen through the underlying liquid metal, and epitaxial growth of Al2O3 on the existing composite body. The roles of Mg and Si in the composite growth process are discussed.

The subject of this research is the monumental vocal-symphonic piece of the prominent Russian composer of the second half of the XX century Boris Tishchenko. His Symphony No.6 s based on the poems by A. Naiman, A. Akhmatova, O. Mandelstam, M. Tsvetaeva and V. Levinzon, completed in 1989, and tribute to Yevgeny Alexandrovich Mravinsky, who passed away a year before. Poetic lines that form the backbone of the symphony contain multiple images resembling death, which imparts a profound meaning, a moment of personal experience in dedication to the prominent conductor. Special attention is given to the symphonic dramaturgy of the Symphony No.6, the problem of interrelation between music and poetry, realization of the complex literary texts in the ultimately modern symphonism of Boris Tishchenko. The conclusion is made that Tishchenko is absolutely seamless in this vocal-symphonic opus and reveres his coauthors. The translates everything into the music, without missing a tiny thing that can reveal its meaning and beauty. At the same time, the circle of poetic images, semantics of the verse were transformed in accordance with his worldview. The novelty is defined by the fact that this article is first in Russian musicology, to comprehensively analyze the Symphony No.6  by Boris Tishchenko, reveal its semantics, and performance difficulties. The author attributes this symphonic composition of Boris Tishchenko to most remarkable in the history of Russian music.

Abstract The results and performance of an enterprise are the result of the decisions taken by the management of the entity, decisions which are the result of a complex procedure of processing and analyzing the relevant data and information provided by the information system available. In other words, appropriate and correct decisions that lead to the achievement of the objectives and attainment of higher performances are dependent on the quality and quantity of the information. Consequently, accurate information generates correct decisions. Due to of its qualities (relevance, intelligibility, credibility and comparability), accounting information occupies a very important place in the architecture of the economic information system, having the highest degree of certainty and providing the possibility of an accurate representation of economic phenomena and processes, both at micro, as well as at macroeconomic levels. Hence, we can say that the “final outcome of accounting”, namely accounting information, is one of the most important pillars of the elaboration, substantiation and decision-making process. Starting from this premise, this article aims to capture the main features of accounting information, which qualifies it as the object and the subject of the management system.

Lease Agreement

Land is the most important object of the environment. It is an indispensable means of production in agriculture, the territorial basis for the location of various objects. It is argued that the proper functioning of land lease relations is a guarantee of sustainable economic circulation, a guarantee of the exercise of rights and performance of duties by both the lessor and the lessee of the land. The issue of renewal of the land lease agreement after its expiration is debatable. The purpose of the study is to outline the existing theoretical and law enforcement problems regarding the renewal of the land lease agreement, to make proposals to eliminate the latter. To achieve this purpose, a system-structural method of scientific knowledge was used, which helped analyse the prescriptions of the legislation on renewal of the land lease agreement, their relations and interaction were highlighted. The study proves that the lessee's pre-emptive right exists to renew the land lease agreement only for the same period and on the same terms and in the absence of objections to such renewal by the lessor. If the lessee tries to change the essential terms of the land lease agreement and in the absence of the lessor's consent to such changes, the lessee's pre-emptive right to enter into a land lease agreement for a new term is terminated. It is emphasised that in each dispute it is necessary to establish the good faith of the lessor’s actions to refuse to renew the land lease agreement with one person (lessee) and the subsequent conclusion of the agreement with the new lessee. The use of the category of "less protected" party in land lease legal relations appears debatable, because depending on the subject composition of the parties to these legal relations, such a party can be both a lessee and a lessor. It is concluded that the Supreme Court should unify the practice of applying the provisions of the law on the renewal of the land lease agreement (only in combination with other regulations or autonomously, with the use of the principle of "tacit consent"). The possibility of autonomous application of such instructions is indicated by the provisions of the Law of Ukraine “On Amendments to Certain Legislative Acts of Ukraine Concerning Counteraction to Raiding”. The revealed shortcomings of the legal regulation of the renewal of the land lease agreement after its expiration indicate the directions of improvement of the legislation in land lease, which has practical significance

Is Value

The pace of business and technological change continues to accelerate and the gap between business requirements and the capability of Information Systems (IS) groups to deliver, is getting wider. Very often both business and IS executives fail to understand the value of their IS investments and the factors that underpin IS performance. What is required to address these issues is a broad range of metrics to gauge both IS value and performance. The fundamental principle underlying the approach described in this chapter is that measurement should be used as a catalyst for change. “You cannot fully understand a subject until it is measured,” is a cliche from a famous physicist. The subject matter under review is that of the overall effectiveness and efficiency of an IS group in meeting the business needs. The emphasis is more on the information systems that provide business functionality than on technology processes and technical infrastructure issues. IS management is particularly challenging as it usually lacks mature measurement. This is paradoxical as the IS industry promotes the use of information systems to more effectively manage businesses.

The subject of this analysis is a solar cooling system based on a novel hybrid steam Rankine cycle. Steam is generated by the use of solar energy collected at about 100° C, and it is then superheated to about 600° C in a fossil-fuel-fired superheater. The addition of about 20–26 percent of fuel doubles the power cycle’s efficiency as compared to organic Rankine cycles operating at similar collector temperatures. A comprehensive computer program was developed to analyze the operation and performance of the entire power/cooling system. Transient simulation was performed on an hourly basis over a cooling season in two representative climatic regions (Washington, D.C. and Phoenix, Ariz.). One of the conclusions is that the seasonal system COP is 0.82 for the design configuration and that the use of water-cooled condensers and flat-plate collectors of higher efficiency increases this value to 1.35.
