Territorial interaction is the basis for the development of a small innovative enterprise and other territorial enterprises
Authors: Ponomarev V. A. , Petrov M. V.
Published: February 2019

The interaction of a small innovative enterprise with territorial enterprises aimed at their socio-economic and innovative development is examined on a specific example, which is important for the development of the regional economy. The authors determine and examine the major areas of enterprise cooperation, access their state and suggest the development indicators. This paper describes the influence of state support through the Innovation Promotion Fund on the development of small innovative enterprises, as well as other territorial enterprises that receive orders from these organizations. The results of the study demonstrate that territorial enterprises can create a system of close cooperation at the local level, promoting their development on terms of mutual interests. The private sector shows interest in participating in the production of innovative products. The proposed model of building an innovative territorial business can be applied by many small, medium, large enterprises in the field of electronic component base, as well as in other industries to create a successful innovation project. Further improvement of the state policy in relation to small innovative enterprises can accelerate the transformation of these enterprises into independent, in-demand research engineering and technology organizations that ensure the development of existing manufacturers of high-tech products based on contract manufacturing.
Vision Actualisation and Spirituality: A Theoretical Model
Authors: Mishra Paritosh , Shukla B. , Sujatha R.
Published: February 2019

As one stretches open the rolled-up scrolls of not-so-distant history, one can see instances of several Corporate scandals having marred the international business firmament over the years. This has led to a heightened recognition of the importance of spirituality, ethics and values in organisational life. The current study presents a theoretical model regarding how spirituality and organisational vision actualisation can coexist and dialectically influence and reinforce each other in a meaningful way and ensure fructification of long term objectives and sustenance of organisations. The model proposes that conceptual ramifications of organisational spirituality are organisational ethics, values and moral standards, which, when practised, give concrete manifestation to augmentation of productivity and lead to growth, fruition of organisational objectives and long-term sustainability of the organisation.
The Advertising Side of ‘Sahib Bibi Aur Ghulam’- Introducing Spiritual Substantiation
Authors: Jha P. N.
Published: February 2019

The present paper drawn on the advertising material of a famous Hindi motion picture – Sahib Bibi Aur Ghulam, depicts the case of a deceptive advertisement for a product, Mohini Sindoor, through a sensitive example. A carefully written copy of the ad, augmented with a well-planned ad campaign completely fails to deliver the benefits it is supposed to accomplish, and thus leading to a mental agony to not only the consumer but also to an intermediary. The paper also presents a unique way to self-regulation by the advertiser of Mohini Sindoor, and further introduces a novel form of ad substantiation – Spiritual Substantiation, to the advertising literature.

Published: February 2019

AbstractThe electron-spin-resonance spectra of transition metal ions Fe in the HgSe matrix are analyzed. The spectra have an appearance typical of the Fe^3+ ion, i.e., they consist of five fine-structure lines with a splitting that corresponds to a weak crystal field. The spectra are observed at temperatures of up to 50 K. The spectral lines are deformed and have a Dyson shape. An analysis of the temperature dependences of the line amplitudes shows that a transition from paramagnetic ordering to ferromagnetic ordering occurs with decreasing temperature, with the Curie temperature T ≈ 7 K.

AbstractThe field electron emission from individual grains on the surface of Si and III–V semiconductors, namely, gallium arsenide, indium arsenide, and indium antimonide is investigated by scanning tunneling microscopy. From the correspondence of the functional dependence of the I – V characteristic to the theory, the emission mechanism is determined as direct tunneling through a depleted or enriched subsurface layer at the voltages V < 1 V and the tunneling emission from the surface electronic states at the voltages V > 1 V. A field-emission threshold of (1–5) × 10^6 V/cm is obtained, which is significantly lower than the values for metals and carbon. The determining factors of this emission mechanism are the Schottky effect, the localization and size quantization of “light” electrons in the surface area of III–V semiconductors, and the presence of a subsurface depletion layer in silicon. According to the data obtained for the values of the field-emission threshold, indium antimonide in the form of submicron grain particles is the most efficient field emitter.
Микроскопическое описание механизма перехода между политипами 2H и 4H карбида кремния
Authors: Кукушкин С.А. , Осипов А.В.
Published: February 2019

Abstract—The mechanism of displacement of one close-packed SiC layer from one minimum position to another on the example of SiC polytype transition 2 H → 4 H has been studied by ab initio methods. It has been shown that the intermediate state with monoclinic symmetry Cm greatly facilitates this displacement breaking it into two stages. Initially, the Si atom chiefly moves, only then—mainly the C atom. In this case, the Si–C bond is significantly tilted in comparison with the initial position, which allows the reducing of the compression of the SiC bonds in the ( $$11\bar {2}0$$ ) plane. Two transition states of this process, which also possess the Cm symmetry, have been computed. It has been found that the height of the activation barrier of the process of moving the close-packed layer of SiC from one position to another is equal to 1.8 eV. The energy profile of this movement has been calculated.

AbstractThe effect of the anisotropy of elastic properties on the thermal conductivity of GaAs/AlGaAs heterostructures at low temperatures is investigated. The effect of phonon focusing on the anisotropy of the thermal conductivity is analyzed. The parameters of the specular reflection of phonons from the boundaries of the heterostructures, which characterize the heat flux in the Knudsen mode of the phonon gas flow, are determined. The angular dependences of the mean free paths of phonons of different polarizations, which determine the thermal conductivity anisotropy of heterostructures with orientations {100} and {110}, are calculated.

AbstractThe time evolution of the ensemble of micropores formed in the near-surface region of silicon during the growth of thin films of silicon carbide is studied by the method of atom substitution. SiC/Si samples are studied by scanning electron microscopy, ellipsometry, and confocal Raman microscopy. The formation of the porous layer involves several characteristic stages: the emergence of single pores, their growth with the formation of dendrite-like structures, and subsequent coalescence into a continuous layer. It is shown that the thickness of the porous layer at the initial stages of the growth is proportional to the cubic root of time. The possible mechanisms of pore formation are discussed and a theoretical model is proposed to describe the dependence of the average thickness of the porous layer on time. The model is in a good qualitative agreement with the experimental results.

AbstractIn this paper, we present the results of studies of the spectral, temperature, and field dependences of the transversal Kerr effect in Ga_1 – _ x Mn_ x As ( x = 0.0066–0.033) layers produced by ion implantation and subsequent pulsed laser annealing. The complicated nonmonotonous nature of the temperature dependences of the transversal Kerr effect and its dependence on the measurement range indicate a magnetic inhomogeneity of the layers. The reasons for the inhomogeneity can be the Gaussian distribution of Mn over the thickness of the layers and the electron phase separation in them. The appearance of new features in the spectra of the transversal Kerr effect is explained by the presence in the doped semiconductor matrix of nanoregions with a higher carrier concentration and a higher Curie temperature and a shift of the Fermi level into the valence band leading to an increase in the energy of optical transitions.

Published: February 2019

AbstractElectric polarization in ErCrO_3 single crystals has been investigated in the temperature range of 5‒370 K. Ferroelectric ordering has not been found in any of the directions. However, electric polarization induced by restricted polar domains of structural origin has been observed. These domains are formed in the crystal matrix near impurity Bi^3+ ions partially substituting Er^3+ ions during the growth of single crystals by the method of spontaneous crystallization using solvent Bi_2O_3. The restricted polar domains form the superparaelectric state. Hysteresis loops with remanent polarization, both along the c axis and in the [110] directions, have been observed below some temperatures T _fr (in the frozen superparaelectric state). The polarization exists up to certain temperatures, which depend on the applied electric field orientation with respect to the crystal axes and exceed significantly temperature T _N of magnetic ordering. These temperatures correspond to the condition kT _fr ≈ E _A for activation barriers at the boundaries of the restricted polar domains.

AbstractTo identify the possible contribution of relaxation processes to the resistance against high-rate deformation, evolution of shock-compression waves in tungsten carbide (WC) ceramics manufactured by spark-plasma sintering at a maximum compressive stress of 27 GPa is measured. Strong elastic precursor decay upon changing the thickness of the samples from 0.15 to 4 mm is revealed. At maximum shock compressive stresses twice exceeding the Hugoniot elastic limit, a decrease in the spall strength value by about 30% from its value in the elastic region is recorded.

AbstractThe formation of a surface layer with silver and sodium concentration gradients in K8-grade glasses as a result of ion exchange is demonstrated by scanning electron microscopy (SEM) and electron probe X-ray microanalysis. The silver ions enriched layers with different thicknesses, depending on the duration of the ion exchange from the silver melt, are visualized in the secondary electrons mode. SEM data on the thickness of the silver enriched layer are in good agreement with the results of calculation from the diffusion equation for silver in glass. The dependence of the silver concentration on the diffusion depth is obtained using elemental composition mapping over the glass cross section. The presence of a layer with a silver concentration gradient leads to formation of a gradient waveguide. Discrete peaks in silver concentration profiles, caused by specific features of mutual diffusion of sodium and silver ions in glasses, are found.

AbstractThe mechanism of excitation of the impurity luminescence in crystalline materials under intense femtosecond laser irradiation has been investigated. It is established that a high concentration of band electrons and holes, which are successively captured by impurity ions, is formed during the femtosecond three-photon ionization of the intrinsic crystalline material. The efficiency of electron–hole excitation of the impurity composition in crystals (as for the electron beam irradiation) is determined by the degree of difference between the electron systems of the s , p , and d subgroups of the outer shell of cations of the intrinsic material and activator.

AbstractFeatures of fluorescence of humic compounds transported by the Lena River runoff in September 2015 are considered. The change in optical properties of dissolved organic matter, namely, fluorescence spectra and absorption coefficients at a wavelength of 350 nm, on the transect from the Lena River delta to the continental slope is demonstrated. For humic compounds of terrigenous origin, the position of the fluorescence maximum has been determined at excitation wavelengths of 270, 310, and 355 nm. It has been shown that fresh riverine waters of Lena River propagate throughout the entire shelf and humic compounds are the main component of the colored fraction of dissolved organic matter. In samples collected near the continental slope, the presence of labile autochthonous organic matter has been revealed. The content of dissolved organic matter in riverine water in 2015 is comparable with results of previous investigations and amounts to 548 μM/L.

AbstractThe characteristics of millimeter-wavelength detectors based on planar Mott diodes with near-surface δ-doping operating without a constant bias are discussed. These detectors have a volt–watt sensitivity of ~1000 V/W with NEP ~ 10 pW/Hz^1/2 in the 150–250 GHz range. The obtained estimates reveal the possibility of an additional order-of-magnitude enhancement of the performance characteristics of detectors with smaller areas of the diode barrier contact.

Published: February 2019

Background: Thyroid eye disease (TED) commonly presents with proptosis, lid retraction, and diplopia. Multiple surgical techniques have been described to rehabilitate the orbit and to restore vision. Balanced orbital decompression is advocated as a standard surgical technique, and image guidance is encouraged to minimize surgical risks. We evaluated the outcomes of patients who underwent image- guided balanced three walls orbital decompression for TED. Methods: An IRB approved retrospective chart review study was performed on all patients who underwent image-guided balanced orbital decompression between January 2010 and December 2016 at West Virginia University Hospital. Demographics, pre-operative and post-operative clinical data including indications, presence of pre- and post-operative diplopia, and exophthalmometry were abstracted. Results: 169 orbital decompressions in 103 patients were performed. The mean age was 56 years, and the prevalence of pre-operative diplopia was 73%. The incidence of new- onset post-operative diplopia was 5.8%. Among patients who had pre-operative diplopia, 48% had resolution of their diplopia post- operatively. The mean reduction in proptosis was 4.7 mm. No patient experienced intraoperative and/ or postoperative complications. Conclusion: Image-gulded balanced lateral, medial and inferior orbital decompression can result in improvement of visual aculty and resolution of pre- existing .diplopia while allowing for significant reduction in proptosis.

The research objectives are to (i) analyze the effects of restoring the growth medium (rhizosphere) toward the production of stevia leaves and (ii) analyze the financial likelihood to restore the growth medium (rhizosphere). The data necessary to answer objective 1 and 2 was retrieved from field research utilizing plot research method along with Complete Randomized Group Design (CRD) comprised of 15 x 2 executions and 3 replications. The plot size used was 2m x 0,6m (1,2m2). Research shows that rhizosphere restoration is able to increase the production of dry stevia leaves. The effort to restore rhizosphere can increase dry stevia leaf production. Financial likelihood analysis of rhizosphere restoration shows that B/C ratio is greater than one, NPV is greater than zero, IRR is quite large at 20%, Unit BEP and Price BEP was exceeded, showing that rhizosphere restoration is financially beneficial. However is still sensitive toward changes of benefit and cost. This research suggests that the increase of dry stevia leaf production should be increased even higher.

Published: February 2019

En el jardín japonés de la sede de la Unesco de París, Isamu Noguchi reflejó su visión abstracta del mundo al evidenciar la relación entre espacio y materia. La utilización de los conceptos de tipo, topos y tectónica dirigió esta actuación –en principio escultórica– a una existencia arquitectónica, gracias a la coherencia entre una estructura formal, una topografía simbólica y una precisa materialización constructiva. Su convergencia en la propuesta permitió la reconceptualización de diseño de jardín acotado y logró trascender lo estético y lo funcional a favor de la experimentación sensorial en su recorrido.

En la historia de la arquitectura moderna de la segunda mitad del siglo xx en la zona metropolitana del Valle de México, tal vez no exista, fuera del Pedregal y Satélite, otro lugar en su tipo que reúna una serie de rasgos propios de la época como Tecamachalco. Sin embargo, a diferencia de estos ejemplos, Tecamachalco no se promocionó a sí misma como paradigmática, ni buscó persuadir a sus futuros habitantes, pues estuvo estratégicamente ubicada y comercializó un estilo de vida aceptado. Su desarrollo evidencia la aclimatación de la arquitectura moderna y el surgimiento del popular moderno. En este escenario las casas de Boris Albin jugaron un papel relevante.

En este trabajo, siguiendo los aportes de Pierre Bourdieu, se analiza la lógica de construcción del curriculum vitae (CV), como un modelo oficial de presentación pública del académico y dos de los efectos prácticos (social y simbólico) que el CV tiene como producción de un “discurso sobre sí mismo”. Luego se reseñan tres problemas de orden teórico y político implicados en la elaboración de los formatos de CV: la vigencia encubierta de la discriminación, la negación de la indeterminación de los tiempos académicos y el ejercicio de la violencia simbólica. En el texto se cuestiona la noción academicista de la excelencia académica.
¿Quién creó este monstruo? Educación y globalización: sus relaciones con la sociedad
Authors: Dias Marco-Antonio
Published: February 2019

En este artículo se exponen algunos elementos que pueden ayudar a comprender la globalización y sus relaciones con la sociedad en el campo de la educación superior. Se comparan dos documentos sobre políticas para este campo publicados en los años noventa por el Banco Mundial y por la UNESCO; éstos han tenido una fuerte influencia respecto a la evolución de las políticas públicas mundiales y se transformaron en una referencia obligada y permanente. Destaca tres momentos en el siglo XX en los cuales las universidades reaccionaron a políticas y a sistemas que deseaban utilizar la educación como instrumento para la manutención de privilegios: la reforma de Córdoba, Argentina, en 1918; Mayo de 1968, y la Conferencia Mundial sobre Educación Superior de la UNESCO en 1998. El autor se pregunta si, en la práctica, estamos volviendo a un sistema de equivalencia de todos los sistemas con el sistema europeo y no a un sistema democrático de convalidación de estudios y diplomas, donde todas las partes tienen derechos iguales y donde la diversidad de los sistemas corresponde a la diferencia cultural y social de las distintas regiones del mundo; a un sistema de control por parte de algunos pocos países que, en la fase actual de la organización mundial, dominarían el comercio educacional.

Poder ver más allá de las maneras de hablar y las formas de comportarse de los/las jóvenes implica entender qué los define, conocer perspectivas a través de las cuales dimensionarlos y resignificar las problemáticas y los desafíos que los rodean. Sin importar el enfoque, la definición de juventud no se debe restringir a una etapa de desarrollo físico, cognitivo o social, o a un posicionamiento histórico y cultural. Debe poder incluir las diferentes variables, cuestiones y factores que la constituyen y la configuran no tan sólo como una etapa de socialización sino como un periodo de construcción de subjetividad, regulación del comportamiento y desarrollo de habilidades para cumplir con los roles y campos sociales propios de la vida adulta. Ante la complejidad y amplitud del tema, esta reflexión cubrirá unas cuestiones sobre el concepto de juventud, algunas perspectivas empleadas para acercarse a lo juvenil y ciertas dificultades y retos que viven los jóvenes hoy.

Mathematical cartography today
Authors: Nyrtsov M.V.
Published: February 2019

For most small bodies of the Solar System shapes the International Astronomical Union recommends to use a triaxial ellipsoid. Today almost all major classes of cartographic projections for the triaxial ellipsoid have been developed. They require systematization, classification and additional research. The archives of libraries accumulated a significant list of paper maps of the Soviet times which are compiled in projections developed in our country. It is necessary to implement those projections in the PROJ.4 library used by GIS. Distortions in map projections can be defined as deformation of a cell. If we imagine that the sphere is covered with a net of regular hexagons then it is possible to estimate distortions in the projection by their deformation on the plane. Now the majority of cartographers use online calculators to define the values required for mathematical cartography. Programs are usually written in JavaScript and require the user to only enter the initial data. These are only some of the problems facing modern mathematical cartography.

Published: February 2019

Background: Using of neuron cells for in vitro neurobiology study is needed. Neuron cell can be obtained from a primary neuron or neuronal cell lines, depend on the aim of the study because both are not equivalent. Various methods are performed to obtain primary neurons from the cortical, hippocampal and whole brain of pre or neonatal rat. The limitations of neuron cells to proliferate so that is necessary to develop a method to isolate neuron progenitor cells (NPCs). The aim of the present study was to isolate NPCs from whole brain post-natal rat.  

Methods: Whole brain were obtained from neonates Sprague Dawley rat. There are 2 step to get NSC; first isolation by taking the brain into the 15 ml of tube with 1 ml of  0,05% trypsin EDTA for 400g brain (incubated in the 370C, 5% CO2 for 10 minutes),  tirturation with adding 1 ml culture medium  and 5 ml HBSS-glucose then filtered by 70μm pore size membrane and centrifuged  2000 rpm for 10 minutes. Second: remove of supernatant with add 1 ml of HBSS-Glucose and taking it into a tube with  35% and 65% concentration of Ficoll then centrifuged at 1800 g for 10 minutes then supernatant were replated twice with poly D lysine (100µg/ml). Characterization of progenitor neuron immunotype was checked by immunohistochemistry with positive marker (NeuN and MAP2) and flow cytometry (PSANCAM+ and A2B5 -).

Results: In this study, our result show that this method does not take longer than one hours and > 95% cells that obtained are expressing PSANCAM+.  After 4 days culture, cells exhibit positive for neuron marker as MAP2 and NeuN.  

Conclusion: The method that our develope to isolate neuron progenitor cell from whole-brain are more effective and more simple with high viability and purity.

FOCALIZATION AS LINGUISTIC PHENOMENON
Authors: Savchenko Yevgenia
Published: February 2019

The article reveals the principal notions of focalization, its functions and features (emphasis and contrast) and their influence on transforming the model of the prosodic structure of the actual division of the utterance. Most frequently, focalization of a text fragment is prosodically expressed with a high register and extension of the tonal range, a raised loudness and a distinct pronunciation. It is established that one of the most well-known factors of the transformation of the prototype prosodic model is the listener’s focus on the most important aspects of the message, the conveyance of the semantic interaction of the message’s specific aspects. Focalization is interwoven with the both possible manifestations of this function: logical stress (in case of the opposition of words) or emphatic stress is implemented by its means. Regarding the changes in the tone direction, it should be noted that this tonal feature does not participate directly in forming an intonation model of the discourse’s focalized structures. It has been observed that there exists a certain modification of the tonal contour formed under the influence of the illocutionary and phase factors and certain types of the subjective-modal meanings.
Key words: emphasis, opposition, focalization, actual division of the utterance, theme, rheme.
