The purpose of the article is to trail regularities of vocal evolution which has formed the transition of stage operatic development from Rossini to Verdi and which has predetermined the performing tradition of Lucia‘s role in Donizetti’s opera “Lucia Lammermoor “(1835) by light coloratura soprano in the second half of XIX century until the present day. The methodology of the study is based on the intonation approach to interaction of music and spoken word in B. Asafiev”s school in Ukraine and which corresponds to the trend of hermeneutics research of the musicology study, as offered in works of L. Zima, E. Markova, A. Roshchenko. The scientific novelty of the work is determined by originality of historical approach to vocal intonation change which has been given birth by Italian romanticism in its dissociation from the R. Wagner approach and which has been accepted as leading approach in operatic performing tradition. This concept coincides with the author's independent analysis of the main heroine in Donizetti’s opera. Conclusion. The role of Lucia in Donizetti‘s opera with its particular style of libretto and manifestation of both femininity and outstanding power resulting in madness forms the parallel to preceding operatic images of hers as well as contemporary images in the days of Donizetti. The composer’s approach to F. Takkinardi-Persiani’s interpretation of this role, however, points to a presentiment of the replacement of "Rossini" soprano by lyrical coloratura in the operas of Gounod. Still this replacement drove the performing of the dramatic role of Lucia by "light" coloratura sopranos - from A. Patti to A. Galli-Kurci, from A. Nezhdanova to E. Miroshnichenko and last not least author of the essay in reference. It is sincerity and faithfulness to the beloved one rather than power of nature which determine the core values of Lucia, forming an analogy to heroines in psychodramas of V. Rebikov, whose genius as a treasure of the Ukraine South became a discovery at the musical theater nowadays. As a consequence ” Lucia di Lammermoor” continuously occupies a significant place in the repertoire of Ukrainian opera houses.

The article reveals some aspects of environmental marketing. The issue of choosing the optimal sales system and certification as part of enterprise policy is studied. It is established that products with excellent environmental characteristics, when organizing the system of its distribution often require specific conditions of storage of goods and compliance with certain rules in its sale. It was found that in order to choose the distribution channels of environmentally friendly products was optimal, it is necessary to follow a certain algorithm. Firstly, it is advisable to have a clearly defined purpose of organizing the sales channel. Secondly, to formulate the conditions and restrictions under which a certain distribution system is chosen. Thirdly, determine sales goals and measures to achieve them. The developed algorithm will ensure compliance of the selected system with environmental, economic, and consumer criteria for the operation of the enterprise within the concept of environmental marketing. Within the concept of environmental marketing, the certification procedure is a means of confirming the presence in the products or activities of the enterprise of different environmental characteristics, which are the core of product policy and are declared in communications. The main role of certification in the formation of demand and promotion of pro-environmental products is to disseminate information about certain characteristics of products or activities of the enterprise and confirm the reliability of such information. The effectiveness of certification as a tool of environmental marketing is to provide consumers and other members of the contact audience with certain guarantees to ensure that all stages of production (or product components) meet certain standards or requirements, as well as minimize the likelihood that the company will adversely affect the environment.

Spectrin is a membrane associated protein most of which properties have been tentatively elucidated. A main role of the protein has been assumed to give a supporting structure to inside of the membrane. As reported previously, however, the isolated spectrin molecule underwent self assemble to form such as fibrous, meshwork, dispersed or aggregated arrangements depending upon the buffer suspended and was suggested to play an active role in the membrane conformational changes. In this study, the role of spectrin and actin was examined in terms of the molecular arrangements on the erythrocyte membrane surface with correlation to the functional states of the ghosts.Human erythrocyte ghosts were prepared from either freshly drawn or stocked bank blood by the method of Dodge et al with a slight modification as described before. Anti-spectrin antibody was raised against rabbit by injection of purified spectrin and partially purified.

Besides stomata, the photosynthetic CO2 pathway also involves the transport of CO2 from the sub-stomatal air spaces inside to the carboxylation sites in the chloroplast stroma, where Rubisco is located. This pathway is far to be a simple and direct way, formed by series of consecutive barriers that the CO2 should cross to be finally assimilated in photosynthesis, known as the mesophyll conductance (gm). Therefore, the gm reflects the pathway through different air, water and biophysical barriers within the leaf tissues and cell structures. Currently, it is known that gm can impose the same level of limitation (or even higher depending of the conditions) to photosynthesis than the wider known stomata or biochemistry. In this mini-review, we are focused on each of the gm determinants to summarize the current knowledge on the mechanisms driving gm from anatomical to metabolic and biochemical perspectives. Special attention deserve the latest studies demonstrating the importance of the molecular mechanisms driving anatomical traits as cell wall and the chloroplast surface exposed to the mesophyll airspaces (Sc/S) that significantly constrain gm. However, even considering these recent discoveries, still is poorly understood the mechanisms about signaling pathways linking the environment a/biotic stressors with gm responses. Thus, considering the main role of gm as a major driver of the CO2 availability at the carboxylation sites, future studies into these aspects will help us to understand photosynthesis responses in a global change framework.

SummarySports photography undoubtedly has a significant place in sports press and publicism. It’s main and primary role is to present sports to the readers as art, which it is. Sport is characterized by dynamic and varied movements, and the main role of sports photography is reflected in the fact that it is in this way that sport shows its essence. Having in mind that photography tells more than a thousand words it sends a clear message to the reader as well to people who are informed about events via sports portals. Sports photography is a multidimensional art for many reasons. When we say “multi”, it primarily refers to a wider range that sports photography has to offer, which means sports photography is not only directed at presenting athletes on the move and the main actors who contribute to achieving the results by their engagement – it also has the role of sports “psychophotography” which is an analysis and capture of the emotional reaction of an athlete after winning or losing from the opposing team.

Subject. The article addresses problems and prospects for the banking supervision development in the Russian Federation under modern conditions. Objectives. We review the essence and methods of organization of the banking supervision, and identify the main problems and prospects for its development. Methods. To provide valid, reliable and reasoned recommendations, we apply normative and integrated approaches to the study of the banking supervision effectiveness in the current circumstances. Results. The paper investigates main problems and development prospects for the Russian banking supervision. The essential importance of supervision comes from the main role of the banking system in maintaining accounts of economic entities and making settlements. Even minor failures or delays in operations can lead to negative outcomes and disastrous consequences for the entire monetary system and the national economy. Therefore, we highlight issues that require attention, and make proposals for further development of the banking supervision. Conclusions. In the context of dynamically developing economy, the banking practice is becoming more complex. As a result, there is a need for new financial instruments that can reduce risks, increase the speed and efficiency of operations and document flow, and help achieve the world levels of introduced standards.

Medical students depend on illustration to learn anatomical facts and details that may be too subtle for the written or spoken word. For surgical disciplines, learners rely on tools such as language, 2-dimensional illustrations, and 3-dimensional models to pass on important concepts. Although a photograph can convey factual information, illustration can highlight and educate the pertinent details for understanding surgical procedures, neurovascular structures, and the pathological disease processes. In order to understand the current role of medical illustration in education, one needs to look to the past to see how art has helped solve communication dilemmas when learning medicine. This paper focuses on Max Brodel (1870-1941), a German-trained artist who eventually immigrated to the United States to pursue his career as a medical illustrator. Shortly after his arrival in Baltimore, Brodel made significant contributions to medical illustration in Gynecology at John Hopkins University, and eventually in other fields of medicine such as Urology and Otolaryngology. Brodel is recognized as one of America’s most distinguished medical illustrators for creating innovative artistic techniques and founding the profession of medical illustration. Today, animated computer based art is synergistically used with medical illustration to educate students about anatomy. Some of the changes that have occurred with the advancement of computer technology will be highlighted and compared to a century ago, when illustrations were used for teaching anatomy due to the scarcity of cadavers.

Effective Instrument

We discuss the role of linguistic metaphors as a cognitive frame for the understanding of genetic information processing. The essential similarity between language and genetic information processing has been recognized since the very beginning, and many prominent scholars have noted the possibility of considering genes and genomes as texts or languages. Most of the core terms in molecular biology are based on linguistic metaphors. The processing of genetic information is understood as some operations on text – writing, reading and editing and their specification (encoding/decoding, proofreading, transcription, translation, reading frame). The concept of gene reading can be traced from the archaic idea of the equation of Life and Nature with the Book. Thus, the genetics itself can be metaphorically represented as some operations on text (deciphering, understanding, code-breaking, transcribing, editing, etc.), which are performed by scientists. At the same time linguistic metaphors portrayed gene entities also as having the ability of reading. In the case of such “bio-reading” some essential features similar to the processes of human reading can be revealed: this is an ability to identify the biochemical sequences based on their function in an abstract system and distinguish between type and its contextual tokens of the same type. Metaphors seem to be an effective instrument for representation, as they make possible a two-dimensional description: biochemical by its experimental empirical results and textual based on the cognitive models of comprehension. In addition to their heuristic value, linguistic metaphors are based on the essential characteristics of genetic information derived from its dual nature: biochemical by its substance, textual (or quasi-textual) by its formal organization. It can be concluded that linguistic metaphors denoting biochemical objects and processes seem to be a method of description and explanation of these heterogeneous properties.

Cycle Regulation

Uninhibited proliferation and abnormal cell cycle regulation are the hallmarks of cancer. The main role of cyclin dependent kinases is to regulate the cell cycle and cell proliferation. These protein kinases are frequently down regulated or up regulated in various cancers. Two CDK family members, CDK 11 and 12, have contradicting views about their roles in different cancers. For example, one study suggests that the CDK 11 isoforms, p58, inhibits growth of breast cancer whereas, the CDK 11 isoform, p110, is highly expressed in breast tumor. Studies regarding CDK 12 show variation of opinion towards different parts of the body, however there is a consensus that upregulation of cdk12 increases the risk of breast cancer. Hence, CDK 11 and CDK 12 need to be analyzed to confirm their mechanism and their role regarding therapeutics, prognostic value, and ethnicity in cancer. This article gives an outline on both CDKs of information known up to date from Medline, PubMed, Google Scholar and Web of Science search engines, which were explored and thirty relevant researches were finalized.
