Technological Peculiarities of Epsilon Ferrite Epitaxial Stabilization by PLD

The present paper describes the technological peculiarities relevant to the nucleation and further epitaxial growth of the metastable epsilon phase of iron oxide by means of pulsed laser deposition (PLD). The orthorhombic epsilon ferrite ε-Fe2O3 is an exotic member of a large family of iron oxide polymorphs, which attracts extensive attention nowadays due to its ultra-high magneto-crystalline anisotropy and room temperature multiferroic properties. Continuing the series of previous publications dedicated to the fabrication of ε-Fe2O3 films on GaN, this present work addresses a number of important requirements for the growing conditions of these films. Among the most sensitive technological parameters, the growth temperature must be high enough to aid the nucleation of the orthorhombic phase and, at the same time, low enough to prevent the thermal degradation of an overheated ε-Fe2O3/GaN interface. Overcoming the contradicting growth temperature requirements, an alternative substrate-independent technique to stabilize the orthorhombic phase by mild aluminum substitution is proposed. The advantages of this technique are demonstrated by the example of ε-Fe2O3 films PLD growth carried out on sapphire—the substrate that possesses a trigonal lattice structure and would normally drive the nucleation of the isostructural and energetically more favorable trigonal α-Fe2O3 phase. The real-time profiling of high-energy electron diffraction patterns has been extensively utilized throughout this work to keep track of the orthorhombic-to-trigonal balance being the most important feed-back parameter at the growth optimization stage.

Artisanal experiences in Arpi: Colours and raw materials of Apulian red figure production

This work aims at studying the manufacturing and technology peculiarities of Apulian red figure (4th − 3rd century BCE) production from Arpi. In particular, the relationship between the red figure production from Arpi with coeval pottery of different classes retrieved in the same contexts in Arpi is investigated, as well as the connection between the red figure production from Arpi and same class vases from different Apulian sites. This goal has been achieved through widening the archaeometrical studies so far performed to red figures finds from two more tomb complexes in Arpi – i.e. tomb of the Niobids vase and 4/2004 tomb – and also organically reorganizing the so far obtained experimental data on Arpi findings of various ceramic classes. The systematic characterization of red figure vases was obtained by Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray Spectroscopy (EDS), Powder X-ray diffraction (PXRD) and Raman Spectroscopy. Analytical data allow to define the elemental and mineralogical composition of ceramic pastes and identify pigments and coatings.The results allow to validate the archaeological hypotheses that Arpi red figure production is different from the one from other Apulian areas and that pictorial experiences were shared among tombs, domus and ceramic production in Arpi.

ANALYSIS OF PARAMETERS AND MODELING OF WEAR ROLLS OF HIGH-SPEED WIRE BLOCKS

Research on the study of features and modeling of wear of rolls remains relevant, due to the need to predict the stability of rolls and determine their costs. The importance of such research increases with the introduction of new roll materials, in particular tungsten carbide alloys.
 The processes of hot rolling are characterized by the simultaneous action of several main mechanisms of wear. Various models for predicting wear are known for these mechanisms, but under current conditions there is a need to develop local models that take into account the peculiarities of technology. Such conditions include high-speed wire blocks.
 The aim of this work is to analyze the parameters of high-speed rolling according to the level of their impact on the wear of the rolls and to develop a model of wear of the rolls of the unit based on the actual wear of several sets of rolls. For the analysis the results of measurements of wear of four sets of rolls which were executed by an optical method and calculated parameters of rolling on usual technology are used. Correlation analysis was performed, using the indicator of wear intensity, as the ratio of maximum wear to the amount of rolled metal in the caliber. A linear dependence was chosen to build the regression model.
 According to the results of the analysis of the wear rate and rolling parameters in the high-speed wire block, it is established that the well-known tribological rolling parameters vary according to the block modules in a rather narrow range, which does not reveal their effect on wear. That is, the effect of these parameters is approximately the same for all modules of the unit, so it is not statistically confirmed.
 The correlation analysis revealed the most significant parameters of rolling by the effect on the wear rate, namely the relative velocity of the cell, the elongation coefficient and the cell shape parameter. For these parameters, a regression model was obtained to determine the wear rate. The model confirms the adequacy and provides an acceptable level of accuracy in determining the wear of the rolls of the block.
 The obtained regression model can be used to determine the durability grooves rolls of the block and predict the expense of rolls, as well as to adjust the technological parameters to reduce wear and expense of rolls.

Technological peculiarities of strengthening RC members with prestressed FRP laminates

There is a general agreement on the benefits of using FRP materials for structural retrofitting. Full potential of this high strength material can be implemented by the process of prestressing. However, prestressing has a number of nuances and can be compromised. Therefore, based on the results of a recent experimental study and the experience of other authors, the peculiarities and issues of prestressing FRP laminates are summarized. Current paper includes the steps from the surface preparation, anchoring to commissioning. Also, a novel prestressing system for retrofitting of reinforced concrete members with externally bonded FRP laminates is disclosed. The advantage of the proposed system lies in the fact that efficient corrugated surfaces are employed for compression of FRP reinforcement. Usually, the result of using corrugated surface steel grips would be a fractured laminate, therefore plane surfaces are common in commercially available prestressing systems.

Analysis on the diffusion of RFID technological innovation from the perspective of disruptive innovation

ABSTRACT Disruptive technology has profoundly affected the market environment and business patterns. Traditional and emerging industries are willing to adopt it to nurture their innovation activities and achieve competitive advantage. However, traditional technological innovation theory cannot give accurate guidance because of the peculiarities of disruptive technology. Thus, in this study, we explore the diffusion mechanism of radio-frequency identification (RFID) technological innovation from the perspective of disruptive innovation. We implement maximum likelihood fitting methods and the goodness-of-fit test to analyse the network’s degree distribution characteristics through evolution. Results illustrate that the connection mechanism changes through the evolution process. In particular periods, preferential attachment does not work. Dominant technologies will lose their position with the emergence of disruptive technologies, hence replaced by them. The findings will provide practical suggestions to firms in facilitating their strategic decision-making when faced with disruptive technologies.

The study of technological peculiarities for improvement of chemical and physico-mechanical properties of reaction-sintered ceramic materials based on molybdenum disilicide

Recommended ways to improve the chemical and physico-mechanical properties of reaction-sintered ceramic materials based on molybdenum disilicide have been described. In order to significantly increase the operating temperatures and change to more stringent operating conditions for ceramic products, it is necessary to improve existing methods of processing ceramics and significantly change the development of new ones. Various means for processing of ceramic materials have been studied and analyzed, which include the introduction of activating additives, hardening with dispersed particles, filamentary crystals and fibers and application of a protective coating to prevent rapid oxidation at surface layers. Carrying out partial purification of the initial starting components from various impurities can significantly increase some characteristics of the disilicide of molybdenum ceramics. Disilicide of molybdenum ceramics has been researched to have significant influence on the physical and mechanical properties (thermal conductivity, electrical resistance, coefficient of thermal expansion and strength) of molybdenum ceramics disilicides, which are introduced into the base material both with the initial components and in the process of its technological production. It has been established that it is possible to increase operating temperatures and ensure the use of molybdenum disilicide-based ceramic materials in harsher working conditions can be achieved by introducing of aluminum, boron, beryllium, iron, yttrium, nickel and cobalt powders into the charge, strengthening titanium coating, which includes silicification and titanium technology. It has been researched that at high temperatures and in the presence of molten silicon the synthesis and crystallization of molybdenum dicilicide occur on the grains in the surface layers, as well as dissolution and recrystallization of submicron particles of molybdenum dicilicide take place at certain depth. Based on the published data analysis and conducted research, the complex of measures for improving the chemical and physico-mechanical properties of reaction-sintered ceramic materials based on molybdenum disilicide has been proposed.

PROTECTION OF THE APRICOT CROP AGAINST DISEASES IN THE OSTROV FRUIT GROWING AREA

Due to its physiological, ecological and technological peculiarities of the species, apricot culture involves a whole series of challenges and requires special attention and fruit growers’ skillness. Being an early flowering plant, sensitive to various diseases and pests, root asphyxiation, spring frosts and other unfavorable factors, yields are often reduced and are a factor that is limiting the areas and farmers' interest in the expansion and development of this crop. Also, the complex of diseases and pests to which this culture is exposed may cause the manifestation of the enigmatic disease called apoplexy or premature demise of the apricot. The paper highlights the importance and special role of effective disease control in an apricot orchard in the southern area of Dobrogea in order to obtain a quantitatively and qualitatively increased yield. A total of 11 phytosanitary treatments were applied to control brown rot, gumspot of stone fruit, scab and powdery mildew. The assessments at 7-10 days after each treatment for Comandor and Farbaly varieties proved a good efficacy ranging from 86.67 to 100%. So that the production of apricots intended for sale was approx 12 tons per hectare.

Agrotechnological peculiarities of crop combination in Beta vulgaris subsp. vulgaris cultivation in vertical hydroponics

The dispensing of vertical cultivation technology in greenhouses in Russia has been held back due to deficiency of a specific assortment of vegetable plants. The studies with the possible species of cultivated crops for vertical hydroponics were carried out in Omsk State Agrarian University. The growth of Beta vulgaris subsp. vulgaris is attractive for getting “baby green”. The study of the technological peculiarities of Beta vulgaris production and the compilation of a scientifically grounded crop rotation in a container-type greenhouse with vertical cultivation of crops is the goal of research work. For growing green crops in vertical container-type greenhouses, including Beta vulgaris cutting, the sowing of seeds can be in the seedling department, bypassing the germination chamber. Beta vulgaris seedling period is 7 days, then within 3–4 months the “Baby greens” leafs are cut, the required parameters are reached by the plants in three weeks, namely leaves are cut about 4–6 times from each container, after that a turnover is performed. The proposed rational system of using the area promote increasing the amount of cut green from 0.25 to 2.0–2.86 kg from the production section. Agrotechnological measures for the use of crop rotation in the cultivation of Beta vulgaris in vertical hydroponics allow starting an autonomous mobile complex with maximum efficiency.

Technological Peculiarities of Old Russian Books as Reflected in Early Modern Inventories of Monastic Libraries

The paper analyzes inventories of the late 15th–17th centuries from four major Russian monasteries: St Cyril’s of Belozersk, The Solovetsky monastery, Joseph-Volokolamsk monastery, and The Holy Trinity – St Sergius monastery. These inventories list the monasteries’ property for its safekeeping. The inventories of monastic libraries contain valuable information about the system of book keeping and the development of bibliography in Old Rus’. They also provide some clues for attribution of books, which can help in reconstructing the concepts of bookmaking technologies in Early Modern period. These technological notes in descriptions of books are organized according to the system created by the inventories compilers: the format, the binding, the artistic values, the type and technique of writing, the page’s composition, the writing material, the state of preservation. The paper shows that the major goal in creating these inventories was to single out the most important elements allowing to recognize the book. Yet the description of these elements was not uniform. The attention was mainly directed to external attribution of a book. From the second half of the 16th century the cursive writing and the so-called metnoe pismo (a sort of scrittura usuale) were already recognized as different from standard book writing and had to be distinguished and indicated in book inventories. The inventories reflected those characteristics of books that were important for the librarians and therefore shaped certain semantic structures in professional mentality of Old Russian bookmen. For modern scholars they can serve as markers that follow the process of the development of book technologies in Early Modern period.
