PECULIARITIES OF PSYCHOLOGICAL COUNSELING WITH CIVIС IDENTITY PROBLEMS
Authors:   Ivan Franko National University of Lviv, Petrovska Inha
Published: August 2022

The article describes the main stages of psychological counseling work with civic identity problems, analyzes the dynamics of the civic identity of clients during counseling sessions. It was found that the request of most clients was based on deep frustration due to: disappointment in the possibilities of self-realization in the organizational environment of the state; clashes with law enforcement agencies and dissatisfaction with the legislation of their own state; unsuccessful attempts to emigrate. Clients' expectations about the results of psychological work with civic identity concerned the harmonization of relations with the state, the acceptance of their own state, and finding new resources for self-realization in the state of own citizenship. It was found that the main deformation of the civic identity of clients was their focus on the destructive game and scenario interaction with the state, which hindered the normal social self-realization of the individual and led to a constant external search for a "better" state and "better" citizenship; to a lesser extent, another deformation of civic identity was presented - its de facto unformedness. It was determined that the most common games for clients were: "The state oppresses me" (role "Victim", 33%), "If not this state" (role "Offended", 28%); less often - "Privilege" (14%), "Patriot" (14%) and "Exemplary Citizen" (11%). Psychological counseling work with games was carried out in accordance with the postulates of transactional analysis and included the following main stages: 1) awareness of the game (search for the game as a series of complementary transactions that inevitably lead to a destructive result in relations with the state and in civic self-realization), formulation of the thesis (the main purpose of the game), finding clients’ psychological gain, as well as a discussion of the antithesis of the game, the ability to stop it, get out of the game; 2) manifestation of mechanisms of imitation and internalization of civic thinking stereotypes in clients’ childhood in order to find the moment of "beginning" of this game; 3) analysis of the sources of subject-object / object-subject paradigm of the individual's relationship with the state and possible emotional fixations in positions of civic protest or civic conformity, identification of "trigger" situations that trigger the mechanism of game transactions; 4) development of new (non-game) ways of behavior in "trigger" situations of interaction with the state. A comparative analysis of the results before and after psychological counseling showed an increase in the conceptuality and subjective orientation of civic identity, as well as increasing its hierarchical position (representation) in the structure of other personal identities.

In the article, theoretically-empirically analyzes of the correlation of indecision regarding vaccination and social-cultural factors are conducted. The analyses of recent researches point out at spread of indecision regarding immunization against different infectious decisions, including Covid-19. This attitude is created by diverse causes/aspects such as own persuasions, mistrust of government, development of conspiracy theories. In the article, reasons for the emergence of indecisiveness are analyzed, the existing methodologies concerning the issue are considered, and the perspective of the investigation is proposed. The study showed the following results: 30% (n = 80) of the respondents were vaccinated, and 66.3% (n = 177) were not. At the same time, 55.2% (n = 142) consider the threat from Covid-19 as serious. Also, most of the respondents (n = 167) have a positive attitude towards vaccination and are mainly supporters of progressive values ​​(equality of minorities, tolerance towards the LGBT community, etc.). In addition, respondents who see Covid-19 as a serious threat have a positive attitude towards vaccination (p = 0.370). Summing up, the main reason for the hesitation of vaccination is adherence to traditional values. This includes religiosity, family relationships, and parent-child relationships. The main category of these subjects are people aged 25+. Also, in general, the subjects do not trust the authorities and consider their steps regarding Covid-19 to be ineffective. Perhaps this is also one of the defining points in the formation of attitudes towards vaccination, because most of the sample has a positive attitude towards vaccination, but has not decided on this step yet.

Timber, concrete and steel are among the traditional building materials used in the construction of buildings. Since concrete is a durable material, it is a building material used in buildings, highways, dams, sidewalks and many other areas. Wood is one of the oldest building materials, and the use of wood and wood-based materials for structural purposes continues to increase. The deterioration of existing wooden structures may result from fatigue and biological attack over time. The cost of replacing the damaged wooden elements is very high, so it seems more appropriate to repair and strengthen the damaged elements. In this study, 20x20x360 mm solid wood beam is reinforced with fiber reinforced polymers and the effect of fiber reinforced polymers on the bending properties of the beam was investigated. In order to determine the bending properties, three-point bending test was applied to the wood beams. As a result of this study, it was determined that the bending properties of wood beam reinforced with fiber reinforced polymer composites were better than the reference samples.

Published: August 2022

Concrete-filled composite elements have recently gained popularity as beams and columns all over the world. They have advantages similar to reinforced concrete elements, such as the moulding process and the lack of maintenance of the filled concrete, as well as advantages similar to hollow steel elements, such as enhancing compressive strength and bending capacity by using smaller sections. In this paper, the buckling behaviour of thin-walled steel columns with circular cross-section and different filling materials was investigated under uniaxial load. Six different materials (concrete produced using normal aggregate, concrete produced using waste aggregate, waste fine aggregate, waste coarse aggregate, waste iron dust and polyurethane) were used as filling. Filled columns were compared experimentally with hollow thin-walled steel columns that had the same height and diameter. All specimens had the same length (750 mm), same diameter (60.3mm) and the same wall thickness (3mm). Experimental results were compared with analytical results obtained from a calculation done using the national steel design code, Design, Calculation and Construction Principles of Steel Structures 2016. Additionally, columns specimens were modelled in Abaqus software. Conservative and consistent results were obtained from comparing experimental, analytical, and numerical results.

Published: August 2022

Modeling the surface element and support system in deep excavation pits and investigating the deformation mechanism is an important issue. In this study, alternative solution methods for an anchored bored pile model are compared and discussed, and it is aimed to contribute to the studies to be carried out in the deep excavation area. A numerical analysis of retaining wall design is examined in the case of the Sivas cultural center building's deep excavation using Plaxis 2D and GGU-Retain software. Measured field data and simulated results are discussed. As a result, the bending moment and lateral deformation reach a maximum when the foundation pit is excavated to the bottom. It can be said that the lateral deformation value found with Plaxis 2D is within the allowable limits, closer to the field data, and provides sufficient quality. The research results will provide theoretical and practical knowledge for designing and constructing similar deep excavation pits for the optimal strategy.
TACTICS OF EXPLANT CHOICE IN BIOTECHNOLOGICAL STUDIES OF WHEAT DROUGHT RESISTANCE BY EMBRYO CULTURE IN VITRO METHOD FOR BREEDING PURPOSES
Authors:   Ufa Institute of Biology of the Ufa Federal Research Centre of the Russian Academy of Sciences, Kruglova N.N.
Published: August 2022

Drought is assessed as an unfavorable combination of meteorological conditions in which plants experience a long-term water shortage in the air and soil. One of the directions of experimental evaluation of plant drought resistance in vitro is to use embryos at one or another stage of development as explants (embryo culture in vitro). The prospects of this direction are determined mainly by the fact that the embryo has all the morphogenetic potentials of an adult organism (Батыгина, 2014), including the ability to withstand various stresses. In biotechnological studies using in vitro embryoculture, depending on the goals of a specific breeding program, it is important to carry out the right tactics for choosing an embryo as an explant at a certain stage of embryogenesis. It is the chosen stage of explant embryogenesis that determines which method the process of regenerant formation in vitro will follow: indirect (according to the scheme "one embryo → one callus → several regenerants") or direct (according to the scheme "one embryo → one regenerant"). Using the example of spring soft wheat, the article presents an overview of a number of literature and original data on the direction of biotechnological studies of drought resistance using the embryo culture in vitro method. The main attention is paid to the analysis of the structural features of wheat embryos at the early and middle stages of organogenesis associated with the induction of indirect and direct methods of formation of regenerants in embryo culture in vitro.

Substrate activity for seven bacterial strains isolated from three industrial ecotopes (Ufa city) towards the phenol, 2,4-dichlorophenol, 2,5-dichlorophenol, 2,4,6-trichlorophenol, 4-chloro-, 2,4-dichloro-, and 2,4,5-trichlorophenoxyacetic acids was assessed. Since none of the isolates could use dichlorophenols, while almost all strains grew on 2,4,6-trichlorophenol, it can be assumed that for the degradation potential of strains, the spatial structure of the substrate is more important than the amount and position of chlorine. Assessment of the strains growth on chlorophenoxyacetic acids also did not reveal a significant correlation between the complexity of the substrate for the ones and the number and position of chlorine substituents.

To improve the efficiency of bioremediation of soils contaminated simultaneously with oil and highly mineralized waste oilfield waters, salt-resistant hydrocarbon-oxidizing bacteria should be used. In a model experiment, the effect of pollution with oil (5%) and NaCl (1 and 3%) and their combinations, as well as bioaugmentation with the halotolerant destructor strain Pseudomonas songnenensis UOM 4 on the hydrocarbon content and enzyme activity of leached chernozem was studied. Bacterization increased oil degradation by 26.9% in oily soil and by 31.8 and 27.6% in complex contaminated soil (with 1 and 3% NaCl, respectively). In the presence of pollutants, the activity of soil enzymes decreased. The introduction of microorganisms led to a certain increase in the level of catalase in oil-contaminated soil, restored urease reactivity in oil-containing soil and under the combined action of pollutants, and increased invertase activity under combined pollution.

Authors: Thongtong Tiwahporn
Published: August 2022

The study's primary objective is to investigate how Thai EFL (English as a Foreign Language) learners use politeness and complaint response strategies similarly or differently in email communication. Email data are collected from 30 male and 30 female Thai EFL learners. The learners' complaint response strategies for handling complaints include gratitude, apology, explanation, offer, appeal, and guarantee. The study shows that complaint response strategies differ among Thai male and female EFL learners. Compared to the female group, the male group uses the offer and appeal complaint response strategies more frequently. More often than the male group, the female group opts for the complaint response strategy of guarantee. Additionally, the chi-square analysis reveals that the use of the politeness strategy of the hedge is significantly different between the male and female Thai EFL learners with varying levels of English proficiency. The employment of the indirect politeness strategy is another crucial difference between male and female students in the high group. However, there is no significant difference in how male and female English language learners with high and low competence levels utilize the direct politeness strategy.

Published: August 2022

Elucidating the elements involved in the gender development is challenging and transcends the nature/nurture dichotomy. We investigated if gender differences would be more pronounced in older infants (11-18 months) than younger ones (6-11 months); and related to gendered toys (masculine: vehicles, and feminine: dolls, dress-up accessories, and domestic items). We discussed our findings in line with the Dynamic Systems Theory. Mothers filled out an online sociodemographic questionnaire, and the Affordances in the Home Environment for Motor Development – Infant Scale. Gender differences were found just from 12 months on and in three out of the four gendered toys. Girls presented more dolls and dress-up accessories and boys, more vehicles and animal toys. Male gender, number of siblings and older infants predicted higher number of vehicles and animal toys, while only female gender predicted higher number of dolls and dress-up accessories. Socialization influence gender role stereotyping, producing distinct sex-typed toy preferences.

Psychoeducation is generally recommended in the treatment of adult Attention-Deficit/Hyperactivity Disorder (ADHD), but only few studies have systematically assessed the effects of structured clinical psychoeducation. Moreover, although a considerable number of psychoeducational mobile applications exist, none have provided scientific evidence for their effectiveness or safety. Therefore, the present randomized controlled trial investigated a newly developed, free-to-use psychoeducation app for adults with ADHD as a support to a clinical psychoeducation group. 236 adults with ADHD were contacted for study participation, of whom 60 were finally randomized to a psychoeducation group supported either by our developed smartphone app (n = 30) or by traditional pen-and-paper brochures (n = 30). Psychoeducation treatments were conducted in groups of 10, with 8 weekly one-hour sessions between March 2019 and November 2020. Observer-rated ADHD symptom severity (IDA-R interview) was examined as the primary outcome parameter before and after treatment. Across both interventions, ADHD core symptoms were significantly reduced. Notably, the smartphone-assisted psychoeducation was significantly more effective in improving inattention and impulsivity and led to higher homework compliance than the brochure-assisted psychoeducation. No adverse events were reported.

Published: August 2022

Extraction of alkaloids from Alnus nepalensis bark has been successfully carried out and used as a green inhibitor for mild steel corrosion exposed to 1 M H2SO4 solution. Alkaloids have been tested by chemical, UV and FTIR spectroscopic methods.Corrosion inhibition was monitored by weight loss measurement and electrochemical methods(open circuit potential method and potentiodynamic polarization method). Weight loss measurement was employed to study the inhibitor concentration and immersion time effect. Similarly, the temperature effect on inhibition efficiency was also carried out by this method. The maximum corrosion inhibition efficiency observed for 1000 ppm solution for 3 h was 71.94 % at 25 °C. The OCP measurement revealed that alkaloids acted as a mixed type of inhibitor. Potentiodynamic polarization for 3 h immersed samples in the presence and absence of inhibitors was carried out. The corrosion current density was decreased with the increasing concentration. The maximum efficiency of immersed sample in 1000 ppm inhibitor solution was 78.48 %. The adsorption isotherm and thermodynamic parameters were calculated and the energy of activation (Ea) was found to be 71.41 kJ/mol. The positive value of enthalpy indicated that the reaction involves is endothermic.

“Into Human Flesh and the Human Heart”: On Promotionalism and the Long Con of Fintech Credit-Scoring
Authors: Hearn Alison
Published: August 2022

Fintech start-ups, such as Zest AI and LenddoEFL, promise enhanced levels of financial inclusion via the creation of “re-socialized” credit profiles derived from accessing clients’ online banking habits and social media accounts. As our social data becomes credit data, the performance of “appropriate” online selfhood can now, quite literally, become money. This article explores the reputational demands, disciplines, and contradictions of ostensibly alternative computational/platformed credit scoring. It argues that the world of “surveillance capitalism” involves the maintenance of a relentlessly promotional value chain. As we are summoned to assiduously self-promote online in pursuit of a creditable reputation and financial inclusion, the self-reflexive promotional logics of the platforms themselves work to remake the world in their own image, paradoxically undermining the productive economic assumptions upon which they are predicated.

Published: August 2022

Freestyle wrestling is a bright, dynamic and spectacular type of sports competition in the program of the Olympic Games. A type of sport in which the winning result will depend on the athlete's physical qualities and preparation for active physical, functional and competitive activities. Modern wrestling is characterized by very high and comprehensive requirements for the aspects of sports preparation, which makes it possible to predict the choice of relevant, justified and adequate means and methods of training. One of the main places for the training of freestyle wrestlers during their studies in higher educational institutions is classes in the section on this type of wrestling. Sectional classes contribute to the full-fledged physical development of students after the school day, provide an opportunity for emotional relief. The main task in the training of wrestlers during sectional classes is the harmonious development of the athletes' physical qualities. And that is why this stage is a guarantee of better assimilation of technical and tactical actions, which in the future will contribute to the rapid formation of motor skills and skills and their implementation during competitive activities. Accordingly, this opens up a wide range of innovative ways and approaches to improve and optimize the development of the physical abilities of fellow wrestlers, contrary to traditional methods. In the control group, training sessions were held in accordance with the freestyle wrestling curriculum. The training process in the experimental group was implemented according to the recommendations of the complex with ZFP and SFP developed by us. The recommended exercises were incorporated into the warm-up part of the training sessions, the achievement of which contributed to the development of the physical qualities of the wrestlers, increased muscle tone and tended to increase the learned information in the main part of the training sessions. According to the results of the pedagogical experiment, the level of physical qualities in the experimental group improved, which is within 28.9%. Comparing with the beginning of the study, the indicators of the "Reaction" and "Recovery" tests have increased, their result reaches 21%. The special endurance of the young wrestlers of the experimental group increased by 17.9%. The results of the flexibility indicators of the athletes who participated in the study improved by as much as 13%.

Accordingly, the control group, which works according to the training program in freestyle wrestling, has a small positive dynamic of special endurance data, which increased by 4%. The best improvements were found after testing force and reaction, which were 6.8% and 7.8%. The improvements in the flexibility of athletes were smaller, which amounted to 1.3%.

Published: August 2022

The article reveals the structure of the pedagogical technology of formation of secondary school students' motivation for systematic physical education classes. School age, like all ages, is a turning point. It is determined when the child enters school. The transition to a new position, in relation to adults and peers, as well as in the family are determined by how they perform their first important duties, and all this leads to those problems that are not only related to the family, but and with education.

Along with the issues of forming students' motivation to study, it is also necessary to resolve the issue of forming the need for independent and systematic physical education based on the creation of ideas about a healthy lifestyle. The acquisition of this knowledge helps to change the attitude of students to physical culture, encouraging them to become strong, well- developed physically. Socio-economic changes taking place in our country abroad put new demands on pedagogical theory and practice in the field of preparing the younger generation for life and work in the conditions of the formation of new relations. The problem of forming motivations for learning, in particular for physical education, is becoming especially relevant in modern conditions
Plasma Sprayed Coatings for the Improvement of Chemical Resistance of Ceramic Refractories
Authors: Bolelli G. , Cannillo V. , Lusvarghi L. , Manfredini T.
Published: August 2022

Plasma-sprayed ceramic coatings were deposited on refractory substrates to improve their chemical resistance to molten glass. Mullite, coarse and fine alumina powders were employed. Different layers with step-wise varying compositions were deposited in order to avoid dilatometric incompatibility troubles. In all the samples, the top coating consisted of plasma-sprayed fine alumina powders, to achieve low porosity and confer adequate chemical resistance, while mullite was used to match the low thermal expansion coefficient of the porous refractory substrates. The coatings were characterized by SEM, XRD, fracture toughness, abrasion resistance, thermal shock resistance and resistance to chemical attack. Since the overall thermo-mechanical and chemical behaviour is greatly affected by microstructural features, such as porosity amount, stacking sequence of layers and their composition, a FEM simulation of the thermo-mechanical properties (with particular regard to thermal stresses-induced cracking) has been conducted and compared to the experimental results.

Authors: Wank A. , Wielage B. , Grund T. , Rupprecht C. , Angermann K. , Schnick T.
Published: August 2022

There are constantly increasing requirements concerning light-weight concepts in automotive design due to energy saving demands. Additionally reduction of component weight is desired for demountable parts to permit easier handling. One innovative development example in this field is a draw bar consisting of precipitation hardened aluminum featuring significant weight reduction compared to presently applied steel draw bars. However, low wear resistance of aluminum alloys makes sophisticated addition of wear resistant parts in the area of the positive fit necessary. This leads to increased machining time, further costs for purchasing and machining of adapted additional components and further assembling steps. A study on the capability of thermal spray coating deposition in the positive fit area for substitution of the sophisticated wear protection system is carried out. Different HVOF coating systems with variable thicknesses are tested concerning their capability to withstand bending stress. The optimum combination of Ni20Cr bond coats and Cr3C2 - 25 Ni20Cr top coats is applied for prototype production. The prototypes are tested concerning their performance under dynamical load and in corrosion tests. All produced prototypes pass both mechanical and corrosion tests. Prototypes, on which arc-sprayed Ni20Cr coatings are deposited as a low-cost solution, are still in tests.

Published: August 2022

In order to overcome the disadvantage of local carburizing of steel components in contact with light-weight graphite or carbon fiber reinforced ceramic racks alumina based thermal spray coatings are produced as diffusion barriers with improved life time compared to rapidly degrading alumina or boron nitride pastes. The powder flame sprayed coatings are also capable to prevent damage by excess filler material in high temperature brazing processes effectively. Besides graphite also C/C racks are coated with pure alumina, Al2O3-TiO2 and Al2O3-Cr2O3. Conventional powder flame spraying is applied in order to provide a low-cost solution for realization of diffusion barriers. Coatings are characterized by means of optical microscopy and SEM with regard to the interface to the substrates and their porosity. Coated racks are used in field tests for case hardening of steel components. The life time of thermal spray coatings is compared to alumina and boron nitride based pastes. Comparative liquid metal corrosion tests are carried out with NiCr7Si4.5B3.1Fe3 filler at 1,050 °C.

Published: August 2022

A model that takes into account the influence of surface activation by particles of the sprayed material on Cold Spray process is proposed in the present paper. With the help of this model, particle adhesion to the surface is numerically calculated. Some typical dependences of the coated area on the number of impacts for different particle velocities and temperatures are obtained. These dependences are in satisfactory agreement with the results of experiments.

Powder size, which influence on spray particle behavior in super sonic gas flow in and out of nozzle, is one of the most important parameters in cold spray process. In the other hands, it was reported that small particles (smaller than 5ƒÊm in diameter) decelerate significantly close to the substrate by the bow shock in cold spray. In this study, numerical simulation and experiments investigated the effect of the powder size of copper on the cold spray process and the structures and properties of the cold sprayed coatings. In the numerical simulation, it is assumed that gas flow within the nozzle is quasi-one-dimensional isentropic flow of semi-perfect gas. A spray powder of copper is used. Mean diameter of copper powder 1, 5, 10, 15 @and 45ƒÊm are used. Working gas (is nitrogen) pressure and temperature at nozzle-intake are 3MPa and 350 ‹C. With decreasing particle diameter, calculated particle velocity at the nozzle exit increase immediately. So deposition efficiency increase immediately with decreasing particle diameter until 5ƒÊm.

Cold Gas Dynamic Spraying is a relatively new high rate deposition process that uses a supersonic gas flow to accelerate fine powder particles (micron size) above a critical velocity. Upon impact, the particles deform plastically and bond to the substrate to form a coating. In this study, nanocrystalline Al-Mg coatings are produced using the Cold Spray technology. In an attempt to improve the understanding and optimize the process, the effects of substrate preparation and substrates thickness on the overall quality of the coatings are investigated. Two different grit materials are used to prepare the substrates with simple grit-blasting. Results show that the use of different grit sizes leads to changes in the mass deposited on the substrate (deposition efficiency) but has no significant effect on the coating microstructure. Other trials are conducted on samples of different thickness to verify the applicability of the Cold Spray process on thin surfaces. Results show that the Cold Spray process can be used to produce coatings on thin surfaces without noticeable damage to the substrate and with the same coating quality.
Spray Forming Titanium Alloys using the Cold Spray Process

Published: August 2022

Development of new, low-cost methods for spraying near net shapes of Titanium and Titanium alloys is critical for many industries and applications. Direct fabrication technologies would have an impact on many industries because of the potential to quickly manufacture complex parts or additive features with minimal waste. However, currently used high temperature spray technologies (Lasform, thermal spray methods) involve melting and solidification. Each new layer starts out molten, then solidifies, and must eventually cool to room temperature. This report presents results of feasibility tests for development of a new method of direct fabrication of Ti alloy parts at near-net shapes (nns) using the Cold Spray process (CSP). Several Ti-6Al-4V powders including gas atomized, plasma atomized, and hydride dehydride were tested in these experiments. Feedstock powders were characterized for particle size distribution, morphology, chemical composition, hardness, and deposition efficiency. Coatings in thicknesses of 2 mm were sprayed for evaluation of microstructure, hardness, and porosity. Thick rectangular prisms (10 mm) were sprayed for machining tensile specimens. The material properties of as sprayed and post treated coatings by heat-treating and hot isostatic pressing (HIPing) on material properties was studied. Analysis showed that after HIPing the density of sprayed Ti-6Al-4V coupons is near 100% and material properties met or exceed those of wrought material.

Based on the principles of cold spray, Cold Gas Dynamic Manufacturing (CGDM) is a high-velocity metal spraying process capable of the high-rate deposition of dissimilar materials under cold conditions. However, unlike many cold-spraying techniques that have focussed primarily on surface coatings, the CGDM process has been tailored for solid free-form fabrication. Central to the needs of the process is the ability to accelerate the feedstock powder – through entrainment into a high-velocity gas flow – to speeds in excess of its critical deposition velocity. The critical factor here is not the gas velocity but rather the ultimate particle velocity; and it is the drag force experienced by the individual powder particles that affect their velocity. This paper documents the methods used to predict, model and validate nozzle performance – in terms of particle acceleration and ultimate velocity – via Computational Fluid Dynamics (CFD) and Particle Image Velocimetry (PIV). Results are presented and discussed pertaining to the effects of nozzle type (de Laval, MLN etc.) and geometry, as well as gas type (Helium and Nitrogen), composition and temperature.

Cold spray, a new member of the thermal spray process family, can be used to prepare dense, thick metal coatings. It has tremendous potential as a spray forming process. However, it is well known that significant cold work occurs during the cold spray deposition process. This cold work results in hard coatings but relatively brittle bulk deposits. We have investigated the mechanical properties of cold sprayed aluminum and the effect of annealing on those properties. Cold spray coatings approximately one centimeter thick were prepared using three different feedstock powders: Valimet H-10, Valimet H-20, and Broadman Flomaster. ASTM E8 tensile specimens were machined from these coatings and tested using standard tensile testing procedures. Each material was tested in two conditions: as-sprayed and after a 300°C, 22 h air anneal. The as-sprayed material showed high ultimate strength and low ductility, < 1% elongation. The annealed samples showed a reduction in ultimate strength but a dramatic increase in ductility, up to 10% elongation. The annealed samples exhibited mechanical properties similar to wrought 1100 H14 aluminum. Microstructural examination and fractography clearly showed a change in fracture mechanism between the as-sprayed and annealed material. These results indicate good potential for cold spray as a bulk forming process.

Ceramic functional coatings are frequently applied to structure materials in a wide range of mechanical and chemical applications for their specific properties of hardness, passive resistance to chemical aggression and low thermal conductivity. The counter part of those specific properties is a low mechanical and thermal shock resistance. Thus it is of prime importance to investigate the fundamental mechanisms, which governs the failure under thermal shock and thermal cycle conditions to increase the range of reliable industrial applications. The work presented in this paper deals with the Finite Element Modelling [FEM] of the transient thermal fields and associated stresses developed in ceramic coatings during firstly the post deposition cooling step and secondly during thermal cycling conditions. Alumina [Al2O3] and Partially Stabilized Zirconia [PSZ] coatings, which are both widely used in mechanical and chemical industries, are under investigation.

In the last decade 3D-CFD has been successfully established for three-dimensional simulations of fluid flow, mixture formation, combustion and pollutant formation in internal combustion engines. In direct injected engines, the accuracy of simulation results and hence their contribution to design analysis and optimization strongly depends on the predictive capabilities of the models adopted for simulation of the injector flow, spray formation and propagation characteristics. The original KIVA-3V code uses the droplet collision algorithm of O’Rouke for calculating collisions in Lagrangian spray simulation. The modified KIVA-3V code includes no-time-counter (NTC) method which is proposed by David P. Schmidt (2000). The NTC method of calculating spray droplet collisions is both faster and more accurate than the current standard method of O’Rouke. In this work an original and a modified version of KIVA-3V multi-dimensional CFD code is used to simulate the spray resulting from the injection of diesel fuel. Numerical results from original and modified KIVA-3V are compared to experimental data and also results obtained from Fire code.
