Enhancing the aesthetic aspect of the solar systems used as facades for building by designing multi-layer optical coatings

The design of zero-energy buildings can be depending on the effective integration of solar energy systems with building envelopes, where these systems save heat and electricity as well as enhance the aesthetic aspect of the facades. In this paper, the aspects related to the effective integration of buildings with solar energy systems (solar cells and collectors) will be discussed, as well as enhancing the aesthetic aspect of the facades, and since solar energy systems are visible to everyone, their design must adapt to the building structure and the surrounding environment. Solar energy system designers, architects, physicists and other contributors to building energy envelopes must consider the comprehensive concept of it, where buildings are part of the human and social environment and in close relationship with the natural environment, through the use of thin films technology through the design of multi-layers colored optical coatings covering solar panels for building facades. Accordingly, the energy sector should be seen as an area of aesthetic creativity. Two dielectric materials were used, the first is ThF4 with a high refractive index (1.5143) and the second is LiF with a low refractive index (1.393) and for several odd layers, starting from 3 layers and up to 21 layers and for a thicknesses of a quarter wavelength. The design Air/L/H/Glass was applied by the Mat Lab program for the seven colors of the spectrum, So, the aim of this research is determined in designing colored optical coatings for solar systems that enhance the aesthetic aspect of building facades, as well as generating thermal and electrical energy needed to operate the buildings and to find out which color has the best visible reflectivity and solar transmittance better than the rest of the spectrum, all the results exhibit that yellow color has the higher visible reflectivity and higher merit factor, so it is consider the most efficient color for coloring the solar systems than the rest of colors spectrum.

AESTHETIC ASPECT OF EMOTIVENESS OF POETIC TEXT

The study looks for ways of analyzing the aesthetic aspect of emotiveness in a poem. To accomplish the aim, the author undertakes an attempt to study the essence of the image of aesthetic feeling. Since a poetic text appears to be a complex unity of notional, emotive, and aesthetic codes, the methods of cognitive analysis are employed to formalize deep cognitive and emotive constructs that give rise to aesthetic senses within a poetic text. The study relies on the statement that an image of aesthetic feeling has an emergent nature which means that it appears in the process of poetic text writing as a result of a creative impulse of the author (O. Mandelstam). In the study, the image of aesthetic feeling is regarded as an emotive image of the highest level. On the one hand, it is directed at some well-established aesthetic categories, and on the other, it reveals the author’s attitude to them which is manifested through a sophisticated network of images. A step-by-step analysis of Shel Silverstine’s poem “A Light in the Attic” has been suggested to illustrate a possible way of uncovering image(s) of aesthetic feelings inscribed in the text.

On the city brand development: city style as a city brand dimension

The article discusses the issues of the development of the city brand. The main purpose of the study was to identify the factors and components that contribute to the development of the city brand. The city brand model of Thomas Gad has been taken as a theoretical basis of the study. This model describes four dimensions of a city brand: mental, spiritual, social and functional. The author of the article has made an attempt to describe and add one more dimension to above-mentioned model-the dimension of “city style” with its visual and aesthetic aspect. The literature review has been conducted in order to clarify the concepts of “brand” and “city brand”. The questionnaire has been carried out among residents of two cities of Kazakhstan to identify the influence of the city style on the recognition of the city. The above is the theoretical and practical contribution of this study to the development and formation of the city’s brand. The proposal of the author of the study to develop design codes for cities of the Republic of Kazakhstan is of applied importance.

Eliminate obstacles of use the solar systems as buildings facades using multilayers optical interference filters

The Building design in a correct way and totalitarian requires integration of using solar energy technologies in the architectural design stage of the roofs and facades as the most appropriate places to obtain solar energy because it greatly affects the architectural aesthetic. This integration has to be taken into account at the design stage, which leads to effective and attractive solutions. Architecture needs the energy to complete its functions to increases human effectiveness and ability to do its tasks better, solar energy is the main factor of providing the necessary energy due to its abundance as well as being clean energy and does not cause polluting emissions to the environment. To provide a comfortable indoor environment for the occupants, Solar Thermal Collectors (STC) and Photovoltaics Cells (PV) used, which convert solar energy into thermal energy and electrical energy, respectively. The main problem of this study is concerning with the problems of the black color, visible tubes, metallic strip gradients (absorption strip), and welding points of the solar systems which gives the facades of the buildings an undesirable view and weakens the aesthetic aspect of the buildings and limits the abilities of architects to use because of their black color and undesirable aspect. The aim of this study is a design of optical interference filter (multilayer coatings) prepared by RF magnetron sputtering as a solution to the problem of black color, visible tubes, metallic strip gradients (absorption strip), and welding points in solar thermal collectors and photovoltaic cells, which are the main reasons for not using solar systems as building facades, this technique works to increase the efficiency of the solar systems and increase the amount of clean energy generated, also enhancing the expressive and aesthetic aspect of facades of buildings. In the NIR region this filter works as an anti-reflective coating. Also the coating includes a high color reflection at a certain wavelength in the VIS region to give the solar system an aesthetic feature, which is used as building facades by using appropriate dielectric substances with high and low reflective indexes likes SiO2 and MgF2 respectively. The results of the study showed that the increase in the number of layers will lead to an increase in the visible reflectivity peak, while near of infrared region remains an anti-reflective with a high Transmission of solar rays, thus increasing solar systems efficiency.

The Product of Formal Innovation in Contemporary Interior Design Techniques

The product of formal innovation has become a strategy in itself, and because the design development with a technical dimension has become a feature of human life, so the concerned institutions have been referring to this through architecture, including the interior spaces it contains, especially at the level of all materials and raw materials.Therefore, in recent years a phenomenon has emerged that is characterized by the innovation of new design techniques, as the interior designer began to realize the importance of innovation, renewal and development through aesthetic and creative data that takes into account the formation of a future vision in which factors concerned with technical development in contemporary interior design overlap, and by informing researchers about foreign design techniques .Therefore, the problem of the research study was formulated with the following question: Does the product of formal innovation have a role in contemporary interior design techniques? While the importance of research contributes to supplying libraries, especially in the field of interior design, with valuable information that can be referenced by specialists in the field of interior design.While the current research aims to reveal contemporary interior design techniques to reach an innovative design product that achieves the functional and aesthetic aspect of the interior space, while the third chapter includes defining the topic of the research procedures represented by the research methodology based on the descriptive analytical approach, while the research community focuses on adopting the eclectic method Finally, the fourth chapter included extracting the results and conclusions of the research study in addition to the recommendations and suggestions.

Racial Integration and the Problem of Relational Devaluation

This article argues that blacks should reject integration on self-protective and solidarity grounds. It distinguishes two aspects of black devaluation: a ‘stigmatization’ aspect that has to do with the fact that blacks are subject to various forms of discrimination, and an aesthetic aspect (‘phenotypic devaluation’) that concerns the aesthetic devaluation of characteristically black phenotypic traits. It identifies four self-worth harms that integration may inflict, and suggests that these may outweigh the benefits of integration. Further, it argues that, while the integrating process may reduce stigmatization, there is less reason to think that it can do the same for phenotypic devaluation.

The Effect of Three Polishing Systems on the Surface Rugosity of One Composite Resin

Direct restorations in composite resin require superficial rugosity appropriate to guarantee a surface free of biofilm buildup, which interferes with the durability of the restoration, its properties and the aesthetic aspect. Thus, it is relevant to know the behaviour of the finishing and polishing systems. The in vitro study aimed to compare the polishing efficiency of three different polishing systems in promoting the surface smoothness of a nanocomposite resin. Sixty specimens of the nanocomposite resin Filtek Z350 XT (3M) were made, randomly divided into three groups (n=20), according to the tested polishing systems: Enhance (Dentsply), DFL Polishers, and Sof-Lex Spiral (3M). The surface rugosity of the samples was measured by means of the rugosimeter equipment. The data were analysed through statistical tests: ANOVA two-way and post-hoc Tukey. The results indicated Sof-Lex (3M) polishing discs as the ones with the lowest average surface rugosity (0.13µm), presenting statistically significant results (p<0.05); followed by the abrasive rubbers of the DFL system (0.17 µm) and the Enhance system (Dentsply), which showed greater average surface rugosity (0.30 µm). The lowest surface rugosity of the composite resin evaluated in this study (Z350 XT- 3M) was obtained after polishing with the multi-step system (Sof-Lex), from the same manufacturer.
