  • The ability to transform the chloroplast of Cyanidioschyzon merolae was limited by lack of confirmed and reliable promoter sequences (among other reasons), capable of delivering stable or modulated DNA transcription followed by protein synthesis. Our research has confirmed the applicability of three selected chloroplast promoters in C. merolae chloroplast overexpression of the exogenous protein (i.e., chloramphenicol acetyltransferase) and genetic transformation. These results might facilitate further research on genetically modified strains of C. merolae to envisage yet unknown aspect of cellular and plastic physiology as well as C. merolae potential applications as bio-factories or sources of useful chemicals.

  • The aim of the present study isto assess the importance of siderophore producing rhizosphere bacteria on the growth of Brassica junceaunder chromium stress. Pseudomonassp. (A4) produced an iron chelating substance siderophores in iron deficient medium. under chromium stress condition Pseudomonassp. (A4) markedly increased the root and shoot length and also biomass of Brassica juncea as compared to Pseudomonas sp. (A3). This plant growth promotion has been related to the microbial production of siderophore.

  • Remarks on polyphenolic compounds has been arisen since past few years. the flavonoids appears to be the important groups of compounds with their capability to inhibit DNA damage, lipid peroxidation, to quench free radicals and, at least, anticarcinogenic and antiproliferative effects. On the other hand, their mechanism of action is still unexplained. Apigenin and luteolin are the most wide-spread flavones and they exhibited to be useful in chemoprevention. UV spectrometric and DC polarographic studies on these two compounds have been carried out with regard to changing pH. The most significant changes were observed at basic pH. These results could aid to elucidation of their mechanism of action as pH is one of the important factors for bioprocesses passing in living organisms.

  • Based on the scientific and pedagogical analysis of the theory and experience of teaching computer science disciplines, the didactic mechanism for ensuring the continuity of the average (full) general and higher professional education of economists for practical implementation innovative technology of personal experience foundation. The pedagogical conditions for the formation of information competence, including laboratory, design, research work, the use of active teaching methods for acquiring management skills in production and activities of the enterprise. An indispensable requirement for the conditions for the implementation of basic of educational programs is the assessment of competencies. With this the goal was to develop criteria and levels of formation information competence of future economists and carried out complex diagnostics.

  • The purpose of this article is to explore the modern branding - its nature, history, originality, spirit and value to consumers. In particular, graphic design of the brand is an important component in terms of the modern European culture. The scientific novelty of the work implies the study of the contemporary design, which widely embraces the sphere of cultural and social life and can contribute to the development of progressive phenomena in society, as the design can literally be defined as a rethinking, a search for new meanings. The design itself is a versatile means of communication at the level of feelings and meanings. One of its main goals is the harmonization, and even formation of perception of the world, creation of new images or rethinking the essence of ordinary things. Hence, the research in the field of the design development is topical in the worldwide cultural space..

  • The aim of this article is to estimate the coefficient bounds of certain subclasses of analytic functions. We claim that this is a novel and unique effort in combining the coefficient functional along with the new domains and the probability distributions which have not been found or are available in the literature of coefficients bounds. Here the authors analyze these bounds in the special domains associated with exponential function and sine function. Further we obtain Fekete-Szegö inequalities for the defined subclasses of analytic functions defined through Poisson distribution series and Pascal distribution series.

  • VANET is an upcoming technology with an encouraging prospect as well as great challenges, specifically in its security. This paper intends to survey such probable attacks and the correlating detection mechanisms that are introduced in the literature. Accordingly, administering security and protecting the owner's privacy has become a primary argument in VANETs. To furnish stronger security and preserve privacy, one should recognize the various probable attacks on the network and the essence of their behavior. This paper presents a comprehensive survey on diversified attacks and the recommended unfolding by the various researchers which concentrate on security services and the corresponding countermeasures to make VANET communications more secure.

  • Scientific space, one can observe the differentiation of the definition of the terms "value", "value orientations" because it does not yet have a clear standard definition. Many researchers have dealt with this topic, researched, analyzed, observed, and made conclusions. However, there is still a rich scope for research of such phenomena of personal structure as value orientations. Psychologists-researchers who, in their scientific, practical, and theoretical works, dealt with the topic of values and value orientations and came to the general conclusion that values are a structural component of a personality, with the help of which a person achieves a goal, sets this goal, and characterizes position in life. Saw the relationship between values and the basic structures of the personality, including value orientations-considered in values a system of orientation and personality attitudes.
