The article is concerned with the issues of determining and evaluating the economic sustainability of enterprise. The publication analyzes the views of scholars on the definition of «economic sustainability of enterprise». A closer definition of this concept is proposed, according to which under the economic sustainability of enterprise it is advisable to understand its complex ability to respond to and withstand the influence of negative relevant factors of the external and internal environment, while maintaining its internal structure, dynamics of operation, which contributes to the achievement of the main goals of functioning and development of enterprises. The main components of economic sustainability of enterprise are allocated, including: financial, industrial, personnel, organizational, marketing, social, environmental, investment, innovation. The main stages of the process of ensuring economic sustainability of enterprise are proposed, the basis of implementing which is the principles of unity – interconnectedness and subordination of all components of sustainability; complexity, which involves taking into account relevant factors of influence; continuity – implementation of the regulatory process on the basis of permanence and sustainability; adequacy, i.e. compliance of the system with patterns of enterprise development. The proposed components and stages of ensuring and determining the economic sustainability of enterprise are used as the basis of the developed methodical approach concerning its quantitative assessment, which is built up using methods of multidimensional factor, cluster analysis, additive convolution method for calculating the integral indicator of economic sustainability of enterprises. The developed methodical approach was tested on the statistical data of nine machine-building enterprises of Kharkiv region, which proved its applied value and possibility of further use.

Universities are increasingly paying more attention to developing academic entrepreneurship. This paper analyses the existing relationships between the relevant factors that contribute to the development of the entrepreneurial university. A previously validated questionnaire was administered to a sample of 84 deans of a number of faculties in Spain. The aim was to assess the universities’ development in terms of 13 influencing factors in encouraging entrepreneurship. The findings show that universities’ contextual factors had only minor influence on internal factors. Internal resources were found to be moderately or highly correlated with the processes put in place by universities to promote entrepreneurship. In particular, reference to entrepreneurship in a university’s mission, strategy, policies and procedures had a correlation with all the entrepreneurship factors analysed. Support from the management team and organisational design were not among the most important factors; however, they were positively associated with training and research processes, which, in turn, seemed to be strongly related to all factors in the development of the entrepreneurial university, especially with university mission and strategy. The findings show the relationships between the factors involved in the development of the entrepreneurial university. This will help universities to adopt measures that are better suited to promoting entrepreneurship.

Surface-enhanced Raman spectroscopy (SERS) has become a powerful tool for biosensing applications owing to its fingerprint recognition, high sensitivity, multiplex detection, and biocompatibility. This review provides an overview of the most significant aspects of SERS for biomedical and biosensing applications. We first introduced the mechanisms at the basis of the SERS amplifications: electromagnetic and chemical enhancement. We then illustrated several types of substrates and fabrication methods, with a focus on gold-based nanostructures. We further analyzed the relevant factors for the characterization of the SERS sensor performances, including sensitivity, reproducibility, stability, sensor configuration (direct or indirect), and nanotoxicity. Finally, a representative selection of applications in the biomedical field is provided.

The field of plasmonics, an optics discipline that studies the interaction of light with matter for structures with dimensions similar to the wavelength of the electromagnetic radiation affecting them, has been further developed with the support of computational technologies that are capable of performing calculations with large volumes of data to solve the complex problems of this discipline. Some of the problems in plasmonics require the use of algorithmic techniques that can simultaneously handle more than one function that tend not to present their maximum or minimum at the same point, i.e., their optimal performances conflict with each other. In this paper, we present the results of the use of a multi-objective genetic algorithm to obtain the maximum plasmonic resonance in nanoparticles assuming three relevant factors: geometry, current density, and electric field, which are, in turn, the three objective functions for the proposed algorithm. The method used for the characterization of the nanoparticles was a numerical simulation using the finite element method. To verify the results, the electromagnetic radiation patterns and other optical properties of the obtained nanoparticles were compared with those of nanoparticles reported in the literature. Possible applications and work in progress are also discussed.

Abstract Finding the main influencers in brand indicators is a challenge for every marketing manager and researchers working in the branding investments area. How much to invest, which is the proper media channel mix or what is the influence of brand heritage are the questions of interest and which the paper responds to. Therefore, this paper is aiming to analyze the brand performance indicators in 2018 (awareness, trial and usage) for over 700 brands in Romania based on their investment on each media channel for 2014-2018 period and 2014 brand indicators. As for characterization of media investment 47 variables were retained, principal component analysis was used for reducing factors of influence. Thus, four main components were retrieved: media investment in absolute measures, main and second proportion in terms of media channel mix, and qualitative aspects of the brand. In conclusion, some multivariate regressions were built for identifying impact on each 2018 brand indicator using the four principal components and 2014 levels of the brand indicators.

ABSTRACTOld French sentential negation (NEG) represents an important morphosyntactic change that has been investigated by a large number of scholars from different theoretical approaches. From the 12th to the 14th (and mainly in the 13th) century, there are two variants of this variable in competition: NEG with onlyne(the older variant) and NEG withne+pas/mie/point, etc. The research presented in this paper has been motivated by the wish to find relevant factors for this variation in Old French. In order to identify factors of influence on the variable NEG with or withoutpas,mieandpoint, we analyse two subcorpora containing two different text types. The choice of the tested factors is rooted both in variational linguistics and in previous studies on Old French negation, implying (extralinguistic) diasystematic factors like diatopic and diastratic ones as well as intralinguistic factors like transitivity of the verb, word order and clause type. Main findings are the probable relevance of clause type and the influence of socially definable (diastratic) groups. Beyond this, the results across the two different text type are predominantly similar, but we found differences as well. This leads us to plead in favour of the importance of considering the factor text type while working on diachronic corpora.

Logarithmic Growth

Mycobacteriophage R1 was originally isolated from a lysogenic culture of M. butyricum. The virus was propagated on a leucine-requiring derivative of M. smegmatis, 607 leu−, isolated by nitrosoguanidine mutagenesis of typestrain ATCC 607. Growth was accomplished in a minimal medium containing glycerol and glucose as carbon source and enriched by the addition of 80 μg/ ml L-leucine. Bacteria in early logarithmic growth phase were infected with virus at a multiplicity of 5, and incubated with aeration for 8 hours. The partially lysed suspension was diluted 1:10 in growth medium and incubated for a further 8 hours. This permitted stationary phase cells to re-enter logarithmic growth and resulted in complete lysis of the culture.

Amorphous materials are of current interest due to their desirable mechanical, electrical and magnetic properties. Furthermore, crystallizing amorphous alloys provides an avenue for discerning sequential and competitive phases thus allowing access to otherwise inaccessible crystalline structures. Previous studies have shown the benefits of using AEM to determine crystal structures and compositions of partially crystallized alloys. The present paper will discuss the AEM characterization of crystallized Cu-Ti and Ni-Ti amorphous films.Cu60Ti40: The amorphous alloy Cu60Ti40, when continuously heated, forms a simple intermediate, macrocrystalline phase which then transforms to the ordered, equilibrium Cu3Ti2 phase. However, contrary to what one would expect from kinetic considerations, isothermal annealing below the isochronal crystallization temperature results in direct nucleation and growth of Cu3Ti2 from the amorphous matrix.

Strengthening Precipitate

A nickel-base superalloy is essentially a Ni/Cr solid solution hardened by additions of Al (Ti, Nb, etc.) to precipitate a coherent, ordered phase. In most commercial alloy systems, e.g. B-1900, IN-100 and Mar-M200, the stable precipitate is Ni3 (Al,Ti) γ′, with an LI2structure. In A lloy 901 the normal precipitate is metastable Nis Ti3 γ′ ; the stable phase is a hexagonal Do2 4 structure. In Alloy 718 the strengthening precipitate is metastable γ″, which has a body-centered tetragonal D022 structure.Precipitate MorphologyIn most systems the ordered γ′ phase forms by a continuous precipitation re-action, which gives rise to a uniform intragranular dispersion of precipitate particles. For zero γ/γ′ misfit, the γ′ precipitates assume a spheroidal.

Studies of the nature of a surface, either metallic or nonmetallic, in the past, have been limited to the instrumentation available for these measurements. In the past, optical microscopy, replica transmission electron microscopy, electron or X-ray diffraction and optical or X-ray spectroscopy have provided the means of surface characterization. Actually, some of these techniques are not purely surface; the depth of penetration may be a few thousands of an inch. Within the last five years, instrumentation has been made available which now makes it practical for use to study the outer few 100A of layers and characterize it completely from a chemical, physical, and crystallographic standpoint. The scanning electron microscope (SEM) provides a means of viewing the surface of a material in situ to magnifications as high as 250,000X.
