Abstract:

In history of art and architecture, surface has always been the bearer of symbolic and aesthetic values, the subject of theoretical and critical analysis, with various ideological, discursive and philosophical interpretations. The subject of this research paper are different concepts of composition, artistic elements and materialisation of fa?ade surfaces, which have the effect of ?surface depth? as their primary characteristic. By analysing the potential of this concept in articulation of the structure of fa?ade and other surfaces, three main emergent forms were noted: plasticity of surfaces (the use of small fa?ade plastics), double skin fa?ade with unused in-between space and double skin fa?ade with used in-between space. By conducting scientific analyses of theoretical reference sources and characteristic examples, along with the application of the deductive methods, the characteristics of the ?surface depth? concept in architecture were explored, with the aim of systematizing the principles used to achieve it, the possibilities of its application, as well as ways to establish the dual character of spatial planes - surface and volume. This research has contributed to the clarification of this concept and laid the foundation for further research in the direction of finding, chronologically ordering and analysing other examples, in order to enable their more extensive typology and systematization.

Abstract:

The main point of a physical definition of surface forces in the matter in general, especially in the nuclear matter, is that the curvature of surfaces and its variation should be physically defined. The forces are therefore just the vehicles of introducing physics. The problem of mathematical definition of a surface in term of the curvature parameters thus naturally occurs. The present work addresses this problem in terms of the asymptotic directions of a surface in a point. A physical meaning of these parameters is given, first in terms of inertial forces, then in terms of a differential theory of colors, whereby the space of curvature parameters is identified with the color space. The work concludes with an image of the evolution of a local portion of a surface.

Abstract:

Bacterial environmental colonization and subsequent biofilm formation on surfaces represents a significant and alarming problem in various fields, ranging from contamination of medical devices up to safe food packaging. Therefore, the development of surfaces resistant to bacterial colonization is a challenging and actively solved task. In this field, the current promising direction is the design and creation of nanostructured smart surfaces with on-demand activated amicrobial protection. Various surface activation methods have been described recently. In this review article, we focused on the “physical” activation of nanostructured surfaces. In the first part of the review, we briefly describe the basic principles and common approaches of external stimulus application and surface activation, including the temperature-, light-, electric- or magnetic-field-based surface triggering, as well as mechanically induced surface antimicrobial protection. In the latter part, the recent achievements in the field of smart antimicrobial surfaces with physical activation are discussed, with special attention on multiresponsive or multifunctional physically activated coatings. In particular, we mainly discussed the multistimuli surface triggering, which ensures a better degree of surface properties control, as well as simultaneous utilization of several strategies for surface protection, based on a principally different mechanism of antimicrobial action. We also mentioned several recent trends, including the development of the to-detect and to-kill hybrid approach, which ensures the surface activation in a right place at a right time.

Abstract:

Background. Students’ conceptualization of learning has been associated with their approaches to studying. However, whether students’ learning concepts are associated with their personal characteristics is unknown. Aim. To investigate whether sociodemographic, education-related, and personal factors were associated with the learning concepts of Norwegian occupational therapy students. Methods. One hundred and forty-nine students (mean age 23.9 years, 79.2% women) participated in the study. The employed self-report questionnaires included the Approaches and Study Skills Inventory for Students, the Rosenberg Self-Esteem Scale, and the General Self-Efficacy Scale. Differences between student cohorts were analyzed with one-way analyses of variance and χ2 tests, whereas factors associated with the students’ learning concepts were analyzed with bivariate correlation and linear regression models. Results. The students’ mean scores on the deep and surface learning concept scales were similar. Spending more time on the independent study was associated with having higher scores on the unidimensional learning concept measure. Conclusions. The students’ learning concept appears to encompass a surface concept as well as a deep concept of learning, and the two ways of conceptualizing learning were positively related to each other. Over time, a mature deep concept may add to, rather than replace, a basic surface concept of learning.

Full text

Abstract:

A newly developed clinical method of indexing tibial torsion uses the medial surface of the tibia as the proximal reference; however, the selection of a specific landmark on the medial surface has not been justified. Three different surfaces relating to the tibial tuberosity were tested using 24 dry tibial bones to determine which provides the most accurate and reliable landmark for use as the proximal reference. The medial surface of the tibia at the inferior point of the tibial tuberosity was the most reliable proximal reference that yielded the highest level of association between the newly developed clinical method and true tibial torsion (r = 0.77). The new method has the potential to describe the anatomy of the leg and to improve the clinical measurement of tibiofibular torsion. (J Am Podiatr Med Assoc 95(5): 481–485, 2005)

Abstract:

The paper describes a model of synthesis and analysis of the application of nano-silica obtained by electron beam evaporation. The authors developed the approach that shows of the specific and fully surfaces of nanopowders to have more significance then the size of the nanoparticles. The experimental results and theoretical models supporting this concept are presented. In particular, the connection between the strength of the epoxy and the total surface value dispersed into epoxy is shown. In the synthesis of large quantities of nanopowder we can use the model concepts to predict specific surface directly from the averaged parameters of synthesis. The main factor for a used synthesis scheme is presented: the multiplication a product of mass performance on specific surface area. The combination of this factor with the model representations of specific surface evaluation allows to estimate the quality and efficiency of the synthesis process. The nanopowder total surface versatility as a criterion of comparability of different modes, and possibly synthesis processes is shown

Abstract:

King has described ‘Kamthi beds’ as the group of rocks disconformably overlapping the Permian coal measures. In an otherwise extremely soil covered areas in the Wardha Godavari Graben. Some of the later workers while projecting on the surface the lithics encountered in the sub-surface drilling in the Godavari Valley Coalfield subdivided these beds into lower, middle and upper horizons, by considering them to have gradational contacts, to account for the biota revealed from these litho-units. A reappraisal of the basic geoscientific database (geological and geophysical) and the interpretations from the surface and the sub-surface lithics have undisputedly shown that the pattern of Gondwana sedimentation in the Godavari Valley, during the Palaeozoic and Mesozoic periods, has been in an oscillating and continental fluvial regime governed by the basin configuration and palaeodrainage interrelated to their development in time and space. The palynofossil content unequivocally proves the presence of the Upper Permian lithics lying buried under the Lower Triassic (Kamthi) sediments. The latter has a widespread expanse in the graben, from the northwest to the southeast which is believed to be due to the further deepening of the basin floor at the time of their sedimentation. The possibility of Kamthi constituting the basal part of the enlarged Maleri sequence of the Triassic lithics is very much indicated thereby defining the base of the Triassic in the Godavari Graben. It is thus, considered undisputed that the Kamthi is nothing more than a concept in the geological history of this part of the Godavari Graben which is defined by its mode of occurrence as governed by the associated tectonism.

Abstract:

It has long been known that materials containing cellulose fibers in their composition are destroyed by molds, microorganisms, actinomycetes, which use cellulose as a carbon source. Different fibrous materials to varying degrees (but always) are affected by molds. It is known that linseed and cotton types of paper are affected by the smallest number of fungi, and sulphate ones by the largest. The most biostable is cotton paper, the composition of which contains chalk in a sufficiently large amount. The observations carried out by the authors showed that the highest biostability (fungal resistance) is characteristic of papers containing chalk and kaolin, the lowest is glued types of paper with a high degree of sizing. Aging of paper with increasing temperature increases the overall susceptibility of all types of paper tested without exception. Obviously, changes in the physical and chemical properties of paper as a result of aging create more favorable conditions for the growth of fungi. It is well known that paper can serve as a medium for the spread of infectious diseases. The authors of the article studied the thermo-physical properties of basalt fiber and investigated the possibility of using it for the manufacture of heat-insulating technical paper.Obtaining materials that are not affected by bacteria, insects and molds (fungicidal,insecticidal) can be solved by using inorganic fibers, which are obtained from almost unlimited natural resources and which have excellent biochemical properties. It should be noted that the concept of "biocidal" paper (material) is collective. It combines species that differ in their ability to kill bacteria (bactericidal), molds (fungicidal), insects (insecticidal). Each of the biocidal types of materials has two or more of these properties.

Abstract:

The purpose of this study is to describe 8th-grade students’ misconceptions in solving surface area and volume of beam and cube problems and their causal factors. This is qualitative descriptive research. Based on the research, students’ misconceptions in solving surface area and volume of beam and cube problems are misconceptions on the concept of a beam, misconceptions on the concept of the cube, misconceptions on the concept of prerequisite material, misconceptions on unit comprehension, misconceptions on the understanding of meaning, and misconceptions on sign and number operations. While the causal factors of misconception are students’ assumptions about the lack of importance of concepts so students only memorize formulas, students are not able to associate one concept with other concepts, lack of understanding concepts in prerequisite material, misunderstanding the meaning of words in a problem, students have difficulty understanding pictures., misunderstanding the difference in the size of area and length.

Full text

Abstract:

Two challenging scientific disciplines, i.e., the physics of glasses [Anderson, Science 267, 1615 (1995); Kennedy and Norman, Science 309, 75 (2005)] and interface chemistry [Sanders, 125 Questions: Exploration and Discovery (Science/AAAS, 2021); Yates and Campbell, Proc. Natl. Acad. Sci. U. S. A. 108, 911 (2011)], converge in research on the dynamics of glass surfaces. In recent decades, studies have revealed that glasses exhibit profound alterations in their dynamics within nanometers of interfaces. Rather, at the free surfaces of glassy materials with arrested bulk dynamics, a highly mobile ultrathin layer is present, wherein molecular mobility is much faster than in the bulk. Enhanced surface mobility has become an important scientific concept and is intrinsic and universal to various categories of glasses (e.g., molecular, metallic, and polymeric glasses), thus having technological implications for processing and applications of glasses. This review provides a comprehensive summary of the historical evolution of the concept, characterization, theoretical modeling, and unique features of dynamics at the surfaces of glasses. Additionally, this paper also illustrates potential advantages of incorporating this concept into designing improved materials with extraordinary properties. We hope this review article will contribute to the current understanding of the unique surface dynamics of glassy materials.

The urgency of development of technology of synbiotic dairy products with metabolites on the basis of microbial consortia of probiotic bacteria is substantiated in the article. The choice of fermentation crops with high biotechnological potential, manufactured by «BIOPROX», is substantiated. Prebiotic components of plant origin with vitamin-mineral complexes – «Flaxseed oil», «Blue iodine» and «Selenium» are involved as energy-biotics. The optimal ratio of fermentation cultures and exopolysaccharides was studied; dynamics of accumulation of bacteria at regulated temperatures; duration of fermentation; physico-chemical parameters of the obtained products. The ratio of fermentation compositions containing microbial consortia for the production of fermented milk products is substantiated: - «Biolon»: Lactococcus lactis subsp lactis, Lactococcus lactis subsp. cremoris, Lactococcus lactis ssp lactis biovar diacetylactis, Streptococcus thermophiles, Lactobacillus bulgaricus in the ratio 0.8: 1: 1.2 (dietary supplement «Flax») at the initial concentration of all cultures in milk formulas 1 · 108 CFU / cm3; - «Bioiod» : Streptococcus thermophiles, Lactobacillus delbrueckii ssp. bulgaricus, Lactobacillus acidophilus, Lactobacillus casei, Bifidobacterium animalis ssp. lactis, Lactococcus lactis ssp lactis biovar diacetylactis in the ratio 1: 2.5: 2 (BAA "Iodine") at the initial concentration of all cultures in milk formulas 1 · 108 CFU / cm3; - «Bioselen»: Lactococcus lactis subsp lactis, Lactococcus lactis subsp. cremoris, Streptococcus thermophiles, Lactobacillus helveticus in the ratio 2: 1: 1 (BAA «Selenium») at the initial concentration of all cultures in milk formulas 1 · 108 CFU / cm3 are substantiated. The expediency of enriching milk formulas with biologically active additives has been established:flaxseed oil - 1.2%; blue iodine - 2.0% and selenium - 1.0%; for obtaining the highest concentrations of probiotic cells in the created new synbiotic dairy products.

Gear tooth surfaces being in line contact at every instant are considered. The dimensions of the contacting surfaces must be limited in order to avoid: (a) the appearance of the envelope of lines of contact on the generating surface Σ1, and (b) the appearance of singular points on the generated surface Σ2. The relations between the developed concepts and Wildhaber’s concept of the limiting pressure angle are investigated. Applications to the worm-gear drive and the generation of a pinion of a Formate gear drive are considered. Computer graphics have been used to illustrate the results of computation.

Full text

Abstract:

Recent large-scale slides occurring during the hydraulic placement of an artificial island berm in the Beaufort Sea resulted from the liquefaction of the berm sand. Subsequent laboratory tests and back analyses have led to advancements in the understanding of the liquefaction potential of sand. Analyses of undrained triaxial tests, undertaken to measure steady state parameters, suggest that there is a "collapse surface" in three-dimensional void ratio – shear stress – normal stress space. A necessary condition for liquefaction is that the soil state lie on this surface. This collapse surface concept is fundamentally an extension of the steady state concepts proposed by others, and in many respects follows the principles of critical state soil mechanics. Replotted published tests support the concept. Parameters used to describe the position of the surface are termed collapse parameters. These can be converted into parameters analogous to Mohr–Coulomb failure parameters and can therefore be used in conventional limit equilibrium stability analyses. Utilizing these parameters overcomes limitations inherent in previously proposed undrained steady state analysis methods. These concepts also provide a basis for a rational explanation of the Beaufort Sea hydraulic fill slides. Key words: liquefaction, sand, hydraulic fill, slope stability, steady state testing.

This paper shows the use of web resources for the creation of Virtual Reality (VR) and Augmented Reality (AR) environments to teaching of topographic surface concepts. The mockups of the topographic surfaces were built with Sketchup software, include graphical representations of level contours, terrain cuts, topographic profiles and embankments. The terrains textures used are satellite photos available by the Digital Globe platform and contribute to improve the visualization of studied concepts. Developed environments enable students to view surfaces in AR ambient, using their webcam devices, such as smartphones, tablets, or notebooks, from a variety of points of view. Each topographic surface mockup has a link to its respective representation in VR, which allows its manipulation and detailed study of each concept. The environments presented in this work can be used in disciplines of Topography, Geography and Descriptive Geometry.

Abstract:

Abstract NASA is currently evaluating architectures to support human missions to Mars. A multitude of concepts are being traded and associated sensitivities are being analyzed. Mars Ascent Vehicle (MAV) propellant supply is a key consideration. Mass constraints for the Mars descent system and in-space transportation present significant architectural challenges that may preclude landing a fully fueled MAV for crew use. In such a case, to ensure the ability of the crewed mission to meet its objectives, propellant should be supplied to the MAV prior to the arrival of the crewed mission from Earth. A concept to robotically transfer liquid oxygen from a separate storage tanker across the surface to the MAV is proposed. This concept makes use of an unpressurized rover and is optimized to maximize the amount of propellant conveyed per trip.

Abstract:

The primary means for electronic position fixing currently in use in majority of contemporary merchant ships are shipborne GPS (Global Positioning System) receivers or DGPS (Differential GPS) and IALA (International Association of Lighthouse Authorities) radio beacon receivers. More advanced GNSS (Global Navigation Satellite System) receivers able to process signals from GPS, Russian GLONASS, Chinese Beidou, European Galileo, Indian IRNSS, Japan QZSS, and satellite-based augmentation systems (SBAS), are still relatively rare in maritime domain. However, it is expected that such combined or multi-system receivers will soon become more common in maritime transport and integrated with gyro, inertial, radar, laser, and optical sensors, and they will become indispensable onboard maritime autonomous surface ships (MASS). To be prepared for a malfunction of any position sensors, their state-of-the-art integrity monitoring should be developed and standardized, taking into account the specificity of MASS and e-navigation safety. The issues of existing requirements, performance standards, and future concepts of integrity monitoring for maritime position sensors are discussed and presented in this paper.
