Plane Fields’ Quadratic Cremona Correspondence Set By Imaginary F-Points
Authors: Короткий  , Korotkiy Viktor
Published: May 2017

Birational (Cremona) correspondences of two planes П, П' or Cremona transformations on the combined plane П = П' represent an effective tool for design of smooth dynamic curves and two-dimensional lines. The simplest birational correspondence is a quadratic map Ω of plane fields on one another. In the projective definition of the quadratic correspondence can participate two pairs of imaginary complex conjugate F-points set as double points of elliptic involutions on the lines associated with the third pair of F-points. In this case, the imaginary projective F-bundles cannot be used for generation of points corresponding in Ω. A generic constructive algorithm for design of corresponding points in a quadratic mapping Ω(П ↔ П'), set both by real and imaginary F-points is proposed in this paper. The algorithm is based on the use of auxiliary projective correspondence Δ between the points of the planes П, П' and Hirst’s transformation Ψ with the center in the one of real F-points. A theorem on the existence of an invariant conic common to Ω and Δ mappings has been proved. Has been demonstrated a possibility for quadratic mapping’s presentation as a product of collinearity and Hirst’s transformation: Ω = ΔΨ. Has been considered a solution for auxiliary problems arising during the generic constructive algorithm’s implementation: buildup a conic section, that is incident to imaginary points, and plotting the corresponding points in collinearity set by imaginary points. It has been demonstrated that there are two or four possible versions of collinearity for plane fields П, П', set by with participation of the imaginary corresponding points, due to an uncertainty related to the order of their relative correspondence. Have been completely solved the problem of mapping a straight line in a conic section within the quadratic Cremona correspondance of fields П ≠ П', set by a pair of real fundamental points, and two pairs of imaginary ones. It has been demonstrated that in general case the problem has two solutions. The obtained results are useful for the development of the geometric theory related to imaginary elements and this theory’s application in linear and non-linear descriptive geometry, operating projective images of first and second orders.

Published: May 2017

Academic Olympics on descriptive geometry are an important form of educational process in conditions when the discipline study’s teaching hours are reduced. The Academic Olympics allow identify talented students and motivate them to find possibilities on solutions for non-standard situations, to promote the formation of such qualities as persistence, endurance, accuracy. The Academic Olympics carrying requires not only organizational measures. Due to a low level of the geometrical knowledge gained at school, students need an additional theoretical training. Without it realizing of young people’s creative potential is impossible. The experience on carrying of the Academic Olympics on descriptive geometry at Bauman Moscow State Technical University and in other higher education institutions of this country allowed develop a technique of students training for such activities. In this paper scientific and methodical questions related to solution for tasks of increased complexity are considered. Simplification of solution algorithm and increase of its visualization can be reached by reduction of metric conditions to affine ones, and them, in turn — to projective ones. The attention in training for the Academic Olympics should be paid to the method of loci. School leavers know only about limited quantity of loci on a plane and have practically no ideas on the elementary loci in space. Therefore studying of loci on a plane and in space is necessary. For the method of loci the essence of simplification, decomposition and increments rules is revealed. If a return problem is solved more simply than a straight one, it is reasonable to use reverse ability method. Often the problem solution becomes simpler when using transformations, in particular, homothety and stretching (compression) transformations. The considered methods are illustrated by specific examples. Assimilation of the methods described in this publication isn't a complete guarantee of students’ success at the Academic Olympics, but, undoubtedly, it will be useful for them as will allow expand knowledge of the subject matter.

Authors: Trespalacios Carrasquilla Alfredo , Rendon Garcia Juan Fernando , Pantoja Robayo Javier Orlando
Published: May 2017

Se analiza el efecto que tienen las restricciones de VaR sobre la selección de la cantidad de contratos forward en un mercado eléctrico y el momento en el que se debe realizar la operación de cobertura, cuando un agente busca maximizar el valor esperado de su beneficio, ajustado por riesgo, y a la vez enfrenta incertidumbre por volumen. Se asume un mercado eléctrico cuyo precio spot presenta características de estacionalidad y reversión a la media y que el precio de los contratos forward exhibe una prima de riesgo (Forward Risk Premium). Como caso de estudio, se presenta el mercado colombiano. Los resultados evidencian que las restricciones de VaR logran modificar la razón de cobertura y también el momento en el que se realiza la cobertura.

Published: May 2017

Este artigo defende um posto de que o tradutor de um texto em uma língua latina enfrenta dificuldades de diversos tipos que podem ser minimizados se uma leitura de texto para formulou sob uma ótica diferente, como, por exemplo, a da Análise do Discurso na linha De Pecheux e seus seguidores. Alguns de seus princípios não aplicam nenhum discurso polemico ou De Senectute de Cicero. São apontados no texto, a partir de pistas linguísticas, como condições de produção de sentido. A análise das fórmulas discursivas limitou-se a uma unidade táctica que corresponde à defesa de uma empresa por um Estado-Membro. Nessa unidade privilegiou-se também uma análise das marcas de argumentação, uma orientação argumentativa e alguns índices de polifonia facilitando-se, assim, uma apreensão dos efeitos dos sentidos do texto.

Giner de los Ríos: la Institución como Ilustración
Authors: Díaz Elías
Published: May 2017

La vinculación de Giner de los Ríos al krausismo y a la Institución Libre de Enseñanza no significa una reclusión en ellos. Su propuesta, que hunde sus raíces en la Ilustración, es la cara optimista o positiva (tesis) del 98 (antítesis), cuya síntesis sería la generación del 14, más científica y política. El pensamiento de Giner no es un pensamiento neutro ni una suma ecléctica carente de originalidad, pero tampoco debe contaminarse de los dogmas de un partido político o un credo religioso. Lo fundamental en él es la conjunción de ciencia y conciencia: racionalismo armónico (frente a los argumentos de autoridad); Estado laico; filosofía social de carácter organicista, que concede protagonismo a la sociedad civil; filosofía política de sentido liberal radical; economía con intervención social; educación como instancia fundamental para la transformación social; razón ética frente a razón instrumental.
«Tan práctico es pensar como cavar la tierra»: filosofía, educación y paisaje en Giner de los Ríos
Authors: Navarro de San Pío Juan
Published: May 2017

Giner de los Ríos transformó el krausismo en una filosofía práctica. De nada sirve la filosofía si no es capaz de suscitar un pensamiento autónomo que inspire a su vez una acción. Y esa renovación filosófica se llevó a cabo por medio de la educación, arte de vivir que permite armonizar la teoría y la práctica, la inteligencia y la voluntad, la naturaleza y el espíritu. Aprendemos a filosofar cuando prescindimos de las ideas ajenas y extraemos el pensamiento del contacto directo con el mundo circundante. De igual modo, captamos el sentido de lo bello cuando nuestra sensibilidad dialoga con la naturaleza sin el reflejo del espejo artístico. El excursionismo y la pedagogía del paisaje confieren sentido estético y ético a la filosofía gineriana, cuya herencia intelectual será más reconocible en Ortega que en la generación finisecular.
Giner de los Ríos, crítico literario
Authors: Juan Penalva Joaquín
Published: May 2017

El artículo ofrece un repaso por las principales aportaciones de Francisco Giner de los Ríos en el ámbito de la crítica, la historia y la estética literarias, tarea que desempeñó fundamentalmente en la Revista Meridional de Granada entre 1862 y 1863 y en algunos periódicos de Madrid. Esos trabajos, sumados a otros posteriores, conformaron su primer libro, Estudios literarios (1866), que tuvo una segunda edición ampliada en 1876, con el título de Estudios de literatura y artes. Después de 1876, Giner de los Ríos abandonó los estudios literarios, aunque regresó a ellos poco después, cuando publicó sus «Cartas literarias» en El Pueblo Español. Esta nueva serie de textos apareció a finales de 1878 y principios de 1879, y suponen su última aportación a la crítica literaria. Entre los autores de los que se ocupa, destacan Ventura Ruiz Aguilera, a quien le dedica cuatro artículos, y Benito Pérez Galdós.

THE IMPACT OF SELECTED PROCESSES AND TECHNOLOGICAL PARAMETERS ON THE GEOMETRY OF THE WELD POOL WHEN WELDING IN SHIELS GAS ATMOSPHERE
Authors: Bradáč Josef , Moravec Jaromír
Published: May 2017

This paper is focused on welding with a consumable electrode in a gas shield atmosphere and its main aim is to show the influence of selected processes and technological parameters on the geometry of the weld pool in terms of theoretical and experimental views. For this purpose, the parametric areas defined by the change of the welding current and welding rate were determined. Apart from the influence of these parametric areas, the influence of other technological input variables, including the wire diameter and preheating temperature, was also studied. The experimentally obtained geometric data of the weld pool can be used for technological welding procedures WPS and especially for simulation calculations to obtain a more accurate numerical model of the heat source. This makes it possible to get accurate simulation results and to better understand the impact of other variables that influence the welding process. This all helps to the optimization of the welding process for several applications.

Authors: Çelik İsmet , Güneş Ebubekir Can
Published: May 2017

The use of biomass fuel pellets is becoming widespread as a renewable and environment-friendly energy. Pellet fuels are produced in various pellet machine types. Pellet machines encounter problems such as pressure irregularities and choke at the initial start for different kinds of biomass feedstock. In this study, disc springs are integrated into a vertical axis pellet machine for a pressure regulation and design optimization. Force-deformation and stress-deformation relations of disc springs are investigated using analytical and finite element methods. Pelletizing pressures were calculated based on disc spring force values using the Hertzian stress formula. Utilized disc springs ensured the pressure regulation, production efficiency increase and damage prevention on the die-roller mechanism.

Authors: Holčapek Ondřej , Reiterman Pavel , Konvalinka Petr
Published: May 2017

This paper describes the effect of cyclic elevated temperature loading on refractory slabs made from high performance, fibre reinforced cement composite. Slabs were produced from aluminous cement-based composites, reinforced by different dosages of basalt fibres. The composite investigated in this study had self-compacting characteristics. The slabs used were exposed to different thermal loading – 600 °C, 1000 °C, six times applied 600 °C and 1000 °C. Then, flexural strength was investigated in all groups of slabs, including group reference slabs with no thermal loading. The results show that the appropriate combination of aluminous cement, natural basalt aggregate, fine filler and basalt fibres in dosage 1.00% of volume is able to successfully resist to cyclic temperature loading. Tensile strength in bending of these slabs (after cyclic temperature loading at 600 °C) achieved 6.0 MPa. It was demonstrated that it is possible to use this composite for high extensive conditions in real industrial conditions.

Published: May 2017

There are different criteria for assessing the appropriateness of an agglomeration technology in the deployment processing of dry, fine and dirty dust burdening in the communal and working environment. Besides the benefit of the environment components, the agglomeration technology offers the possibility of re-processing the material as the primary raw material within a wide range of industries. Preliminary tests have shown that the compressed material remains in the memory from the previous compression. For returning the already processed material into a primary production, it is essential that it is reformed without the need for additional materials, a requirement that can be problematic. This article deals with the modification of a powder material (powder dust from the manufacture of friction components) and the investigation of its properties before and after the compaction processing.
The Identification, Structure, Care, and Conservation of Sawfish Rostra (Rhinopristiformes: Pristidae)
Authors: Byler Jessica
Published: May 2017

Sawfish rostra are commonly found in historic natural science collections, yet there is a scarcity of guidance on their preservation. Rostra are cartilaginous with teeth-like scales. The function and structure of sawfish rostra as well as key mechanical and chemical issues need to be considered for their appropriate care in museum collections. Possible routes of decay are discussed, and methods for the care and conservation of rostra in museum collections are suggested. The species of sawfish can be determined by the morphology of the rostral structure. Physical damage, due to the nature of the material and from handling, often causes deterioration of rostra.

Authors: Jeyam. M Gomathi , Ravichandran Ramanibai
Published: May 2017

Omega-3 family (ω-3) of polyunsaturated fatty acids (PUFA) was considered as an important biochemical for the physiological function of all trophic level animals. In this study, we demonstrated the effect of algal diet on fatty acids composition (FA), antioxidant enzymes and DNA damage of Moina brachiata from Adyar River and Kolavoi Lake. 8 different fatty acids were identified in M. brachiata through GC-MS analysis and we noticed two PUFA (Eicosapentaenoic acid, EPA 20:5 (ω-3); Linoleic acid 18:2 (ω-6)). The dietary fatty acid accumulation and bioconversion capacity of M. brachiata have differed in two lakes fed with algal diet. The high amount of ω-3 PUFA was observed in M. brachiata fed with Scenedesmus sp. in Kolavoi Lake (35.84%) followed by Adyar River (33.78%). PUFA content was significantly declined in wild M. brachiata of Adyar River (17.44%) followed by Kolavoi lake (25.78%). On the other hand, high level of Malondialdehyde (MDA) and decreasing level of key antioxidant enzymes likes Superoxide dismutase (SOD), Catalase (CAT), Glutathione peroxidase (GSH) and DNA damage were observed in wild M. brachiata of Adyar River. Hence, the algal diet could enhance the level of antioxidant enzyme activity by decreasing the level of MDA and it does not show DNA damage on M. brachiata. Overall, the results obtained in this study explored that Scenedesmus sp., has the ability to enhance the PUFA content, antioxidant enzyme activity and prevent the DNA damage in M. brachiata which was declined in the wild animal due to the environmental stress conditions.

The internet is the one of the most important global network and information source in information age. The internet has changed employee’s life enormously. The purpose of this study is to clarify the benefitting situations of employees from e-employee services. For this purpose, a 20-item data collection tool, based on the e-employee services put forward by the Information Council Turkey was developed. Maintained measurement tool was applied on 515 employees residing different regions and provinces of Turkey in the 2014 academic year. As a result, it was observed that employees benefitted from social, health and education oriented services of e-employee at “medium frequency”, whereas they “rarely” benefitted from the economic-oriented services of e-employee. It was found that women used e-employee services more than men. 30-year of age and younger people used e-employee services more often than older people. In addition, those who have higher incomes use e-employee services more frequently than those who have medium or low incomes. Those working in education and finance sectors benefit from the e-employee services more often than those in other sectors.

The authors describe a case of a rare infectious disease of intra-articular tissues of the temporomandibular joint caused mainly by Pseudomonas aeruginosa. In scientific literature, under the heading invasive (malignant) external otitis, we can find cases of an infectious disease of the external acoustic meatus caused by a microbial agent of Pseudomonas aeruginosa which can subsequently penetrate into structures. However, a primary affliction of the abovementioned structures has not been described. Localisation and severity of the infection requires long-term and massive treatment with antibiotics.
How to Choose Your Next Top Salesperson: Multiple-Criteria Approach
Authors: Cvetkoska Violeta , Iliev Filip
Published: May 2017

Background: Choosing the most suitable candidate for the position of salesperson is indeed a complex task for managers because several criteria important for the position should be taken into consideration. Such a choice should be considered as a multiple-criteria problem, which can be solved by using the AHP method. Objectives: The main goal is to investigate which criteria are the most important for the managers in the process of selecting a candidate for the position of salesperson, and on that basis to develop an AHP model for ranking of applicant candidates for this position. Methods/Approach: A questionnaire was created, which was sent to 100 sales managers in companies of different industries in Macedonia, in order to grade the importance of the given criteria. Out of the criteria graded, nine that have the highest average grade of importance comprise one of the levels of the AHP model. Results: An average grade of importance for the criteria for choosing a candidate for the position of salesperson is gained, and an AHP model is developed. Conclusions: The developed AHP model is illustrated through a hypothetical example, and its solution serves as a recommendation for who is the best candidate.

Crambe sp. is an oilseed crop from the Brassicae family and native to the Mediterranean region. It can be converted into a number of industrial and energy uses. Crambe oil is used in introducing in stain, primers, plastic and solid wax, cosmetic and engine portions in the form of nylon-13.13 exclude carburetor as eco-friendly. All these properties make it interesting. This study is the first report on yield, cultivation procedure, and quality characteristics of Crambe sp. cultivated in Turkey. Native Crambe seeds, collected from eight different locations in Turkey, were cultivated under Çukurova conditions in Mediterranean region. Two Crambe species, Crambe orientalis and Crambe tataria, determined at the locations were studied, and some morphological characteristics and oil compositions were sown from cultivars and native forms. Fatty acid composition of seeds was examined with GC and GC/MS. In native populations, high seed oil contents were obtained from C. tataria (Ankara - Faculty of Science and Letters) and C. tataria (Kahramanmaraş-Elbistan), as 45.62 and 45.50%, respectively. The highest erucic acid content (49.0 %) was found in C. tataria (Ankara-Bilkent). In Çukurova conditions, despite cultivated all collected species, just C. orientalis was bloom among this species, and so that seed yield (472.77 kg/ha) oil rate (% 27.43) and erucic acid (41.0 %) could determine just this species.

Motor coordination is proposed to be a relatively stable age-related construct, unlikely to be influenced by aligned experiential factors such as intensive sport-specific training. The purpose of the study is to investigate if there are differences in motor coordination abilities among young artistic gymnasts, swimmers, and ice hockey players.

Methods

The participants of the study were 508 female and 258 male adolescents (age, M = 12.80, SD = 1.10) comprising artistic gymnasts (n = 463), swimmers (n = 70), and ice hockey players (n = 233). The KTK-test protocol was used to analyse their gross motor coordination abilities.

Results

The results of the study demonstrated that gymnasts scored better than ice hockey players and swimmers in the test of walking backwards along a beam, and better than ice hockey players in total motor coordination, hopping over an obstacle, and the test of moving sideways on wooden boards. However, ice hockey players scored higher than swimmers and gymnasts in the test of jumping from side to side. Subsequently, swimmers obtained better results in the test of moving sideways on wooden boards as compared with ice hockey players.

Conclusions

The study results indicate that intensive sport-specific training may extend young athletes’ motor coordination characteristics in the ability areas representative of the sport in which they engage.

In the present study, the effect of different polymerization degree of inulin on the quality parameters of conventional and sugar-free dark chocolate products as well as on the vitality of probiotics used in the chocolates were investigated. To produce sugar-free dark chocolates prepared with the addition of maltitol, Lactobacillus paracasei/L. acidophilus and inulin with DP higher than 23 and lower than 10 were used as probiotic and prebiotic agents, respectively. After 90 day of storage, more than 6 log cfu/25 g probiotics were observed in the chocolates produced by supplementing of 9 log cfu/25 g probiotics. Considering the probiotic level for both conventional and sugar-free dark chocolate, the highest probiotic level was observed in the samples prepared from L. acidophilus and inulin with DP<10. In addition, inulin with DP<10 was found as more suitable in terms of rheological characteristics of the samples. Other quality parameters (texture, colour, melting profile and water activity) changed in narrow range which was allowable when compared with the control samples. Consequently, sugar-free chocolate containing L. paracasei and L. acidophilus could be produced which might satisfy the expectations of the consumers and appropriate to industrial production similar to conventional chocolate. The findings of the present study highlighted the importance of the selection of the most suitable prebiotic/probiotic combination for maximizing probiotic level in the chocolate products.
Train velocity estimation method based on an adaptive filter with fuzzy logic
Authors: Pichlík Petr , Zděnek Jiří
Published: May 2017

The train velocity is difficult to determine when the velocity is measured only on the driven or braked locomotive wheelsets. In this case, the calculated train velocity is different from the actual train velocity due to slip velocity or skid velocity respectively. The train velocity is needed for a locomotive controller proper work. For this purpose, an adaptive filter that is tuned by a fuzzy logic is designed and described in the paper. The filter calculates the train longitudinal velocity based on locomotive wheelset velocity. The fuzzy logic is used for the tuning of the filter according to actual wheelset acceleration and wheelset jerk. The simulation results are based on real measured data on a freight train. The results show that the calculated velocity corresponds to the actual train velocity.

In Situ Lateral Load Tests on Instrumented Bored Piles in Loessial Soils
Authors: Drăghici Sebastian , Marcu Anatolie
Published: May 2017

The aim of the paper is to provide some aspects regarding the behaviour of laterally loaded piles in loessial soils, by presenting and analysing the results of several in situ tests on large diameter bored piles in this type of soil. The major feature of loess is that it exhibits a massive decline of its strength and stiffness parameters when it comes into contact with water, leading to the collapse of its structure even under self-weight and creating difficult conditions for foundations. The load tests were performed both in natural moisture content loess and also in saturated loess. The results obtained by means of instrumentation are back-analysed using current analytical methods and also by finite element method using a numerical model in the geotechnical computation software Plaxis 3D.
Sponsorship investments: do they deliver brand awareness for all sponsors?
Authors: Mpolokeng Sephapo Catherine
Published: May 2017

Sponsorship as a marketing communications tool is well adopted in South Africa across various areas such as sports and entertainment. Although world markets have experienced economic turmoil in the last few years, the sponsorship market may be considered to be thriving as companies use this marketing communication tool as a vehicle to create and maintain relationships. The purpose of this study was to explore which sponsors of the South African National Rugby team are sports consumers aware of as a result of the sponsorship. Literature states that awareness also influences the judgments about brands in the consideration set, even without any brand associations in the consumer’s mind. In low involvement decision; where consumers do not need to search extensively for information in order to make a decision; minimal brand awareness levels may be enough to convince the consumer to make their final choice. The study is exploratory in nature however provides a South African perspective on how effective the sponsorship of the Springbok is with regards to creating awareness of the sponsors among sports consumers. The study made use of a qualitative approach whereby primary data was collected by means of focus groups and naïve sketches. Data collected was analyzed by means of content analysis. The findings suggest that participants were predominantly aware of the key sponsors of the Springboks; these were sponsors who had their branding on the Springbok jersey worn during rugby matches. The factors that participants mentioned to contribute to their awareness of the sponsors were the branding on the Springbok playing jersey as well as television adverts along with other promotional tools. This study urges sponsors to not only rely on the sponsorship initiative to create awareness but rather leverage the sponsorship with tools that are relevant to their target audience. This study contributes to sponsorship literature relating to the effectiveness of sponsorship; particularly from a South African perspective.
The Pay-What-You-Want game: What can be learned from the experimental evidence on Dictator and Trust Games?
Authors: Greiff Matthias , Egbert Henrik
Published: May 2017

This paper introduces the Pay-What-You-Want game which represents the interaction between a buyer and a seller in a Pay-What-You-Want (PWYW) situation. The PWYW game embeds the dictator game and the trust game as subgames. This allows us to use previous experimental studies with the dictator and the trust game to identify three factors that can influence the success of PWYW pricing in business practice: (i) social context, (ii) social information, and (iii) deservingness. Only few cases of PWYW pricing for a longer period of time have been documented. By addressing repeated games, we isolate two additional factors which are likely to contribute to successful implementations of PWYW as a long term pricing strategy. These are (iv) communication and (v) the reduction of goal conflicts. The central contribution of this study is an attempt to bridge the gap between laboratory experiments and the research on PWYW pricing, which relies largely on evidence from the field. By reviewing the relevant experiments, this study identifies factors crucial for the success of PWYW pricing and provides guidance to developing long-term applications of PWYW pricing.

Children’s agency in creating and maintaining language policy in practice in two “language profile” preschools in Sweden
Authors: Boyd Sally , Huss Leena , Ottesjö Cajsa
Published: May 2017

This paper presents results from an ethnographic study of language policy as it is enacted in everyday interaction in two language profile preschools in Sweden with explicit monolingual language policies: English and Finnish, respectively. However, in both preschools, children are free to choose language or code alternate. The study shows how children through their interactive choices create and modify language policy-in-practice. We analyze extracts from typical free play interactions in each setting. We show how children use code alternation as a contextualization cue in both settings, but with somewhat different interactional consequences. Children in both preschools tend to follow the lead of the preceding speaker’s language choice. Code alternation is also a means to manage conversational roles, for example, to show alignment. While the staff give priority to the profile language, the children show through their interaction that skills in both the preschool’s profile language and in Swedish are valuable.
Peacock Ink: Investigation into the Constituents of the Most Prized Ink of Persia
Authors: Zekrgoo Sadra , Nel Petronella , Sloggett Robyn
Published: May 2017

Peacock ink, known as Murakkabi ṭāvūsī, was created and used by Persian master calligraphers especially from the 14th century onwards. It is a sub-category of Persian ink which contains four main ingredients: lamp black, gum Arabic, green vitriol (ferrous sulphate) and gall nut extract (tannic acid). It is differentiated from other inks in that it contains many additional secondary ingredients which will be covered in this paper. Peacock ink derives its name from the range of different coloured materials added to the ink as well as the blue-green undertone this predominantly black ink is said to have. It is reputed to be a high-quality product, rumoured to stay on paper for centuries and is not affected by water, abrasion or other detrimental factors. It was the aim of this investigation to identify and describe in detail ingredients used to make this ink by finding and translating 17 recipes contained in 11 Persian treatises (15th–16th ce). Of the 31 ingredients found, 16 are plant based, 13 minerals, and 2 animal (protein) based, and in all cases water was used as the vehicle.
