Manuel Lima is one of the most prominent figures of data visualization since the publication of Visual Complexity (Lima 2011). In this conversation, Manuel Lima traces back the origin of data visualization to Ars Memorativa, an ancient mnemonic technique to organize information and facilitate its recall. Going back to the origins is an obsession that brought him to collect and arrange into books images of information design from both physical and digital archives. By doing this, Manuel Lima tackled issues related to digital objects and their creation, use, and preservation, with a point of view capable of combining the passion for visualizing information and the profession of UX designer.

Neste artigo, abordaremos metáforas visuais utilizadas na visualização de dados da infografia do célebre designer Nigel Holmes. Isto foi feito mediante o diálogo com a linguística cognitiva e a retórica visual, pela ótica da teoria de design da informação. Para tanto, nossa abordagem é embasada na teoria das metáforas cognitivas, marcadas pelos estudos de Lakoff e Johnson (1980), e a tradição de estudos de figuras de linguagem visual. Nesta análise utilizamos uma taxonomia de figuras de linguagem pictóricas utilizadas em gráficos estatísticos (LIMA, 2018). Ao analisarmos as metáforas pictóricas utilizadas por Holmes, observamos que este designer tem a tendência a sobrepor elementos pictóricos a elementos esquemáticos em seus gráficos estatísticos. Nós cunhamos esta mescla de modalidades gráficas de gráficos pictórico-esquemáticos. Este uso de elementos pictóricos, muitas vezes, humorísticos sobrepostos a dados numéricos precisos foi duramente combatida por teóricos do design da informação como Edward Tufte, na década de 1980. Estes elementos pictóricos foram chamados de chartjunk. Este termo tem servido como uma crítica à elementos visuais consideradas supérfluos em nome de uma abordagem mais neutra na infografia e visualização de dados. No entanto, procuramos entender a escolha do uso de metáforas visuais por Holmes como uma abordagem que não se limita a uma suposta neutralidade de linguagem gráfica.*****In this article, the focus is on visual metaphors used in Nigel Holmes’ data visualizations present in his infographics. This analysis was accomplished by approaching the theory of cognitive linguistics and visual rhetoric from the point of view of information design. Our study is based on the theory of cognitive metaphors, notably the work of Lakoff and Johnson (1980), and the study of figures of speech in visual language. In this analysis, we used a taxonomy of figures of speech for pictorial language in data visualization (LIMA, 2018). When analyzing the pictorial metaphors used by Holmes, we observe that this designer tends to overlap pictorial elements on schematic ones in his statistical charts. We coined this mix of graphic modalities: pictorial-schematic charts (gráficos pictórico-esquemáticos). This use of pictorial elements, often humorous, overlapping precise numerical data was harshly opposed by information design theorists such as Edward Tufte in the 1980s. These pictorial elements were called chartjunk. This term has served as a criticism of visual elements considered superfluous in the name of a more neutral approach to infographics and data visualization. However, we seek to understand Holmes' choice of using visual metaphors as an approach that is not limited to a supposedly neutral graphic language.

The purpose of the article: to identify and systematize the areas and problems of information security that are solved using visual analytics methods, as well as analysis of the applied data visualization models and their properties that affect the perception of data by the operator. Research method: a systematic analysis of the application of visual analytics methods for solving information security problems. Analysis of relevant papers in the field of information security and data visualization. The objects of research are: theoretical and practical solutions to information security problems through visual analysis. Visual analytics in the article is considered from several sides: from the point of view of the areas of application of visual analysis methods in information security, from the point of view of the tasks solved by the security analyst, from the point of view of the visualization models used and the data structures used, as well as from the point of view of the properties of data visualization models. The result: classification of visualization models is proposed, which differs from analogs in that it is based on the analysis of areas and tasks of information security and comparison of visualization models to them. The scope of the proposed approach is the creation of visualization models that can be used to increase the efficiency of operator interaction with information security applications. The proposed article will be useful both for specialists who develop information security systems and for students studying in the direction of training “Information Security”.

Phenomenological Point

This paper gives a multi-disciplinary review of the exploration issues and accomplishments in the field of Big Data and its representation methods and instruments. The principle point is to sum up difficulties in perception strategies for existing Big Data, just as to offer novel answers for issues identified with the present status of Big Data Visualization. This paper gives a characterization of existing information types, scientific strategies, perception procedures and instruments, with a specific accentuation set on reviewing the development of representation approach over the previous years. In light of the outcomes, we uncover detriments of existing perception techniques. This paper will examine utilizing vivid augmented simulation conditions for envisioning, collaborating and sorting out enormous information. It uncovers that a large number of the created applications don't legitimize their ways to deal with introduction or association. A phenomenological point of view of encapsulated recognition and collaboration is examined to ground future turns of events. Besides, we examine the effects of new innovations, for example, Virtual Reality shows and Augmented Reality head protectors on the Big Data perception just as to the arrangement of the fundamental difficulties of incorporating the innovation.

The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

ABSTRACTThe mechanism by which a shepherd satellite exerts a confining torque on a ring is considered from the point of view of a single ring particle. It is still not clear how one might most meaningfully include damping effects and other collisional processes into this type of approach to the problem.

Potential Use

The origin of mica polytypes has long been a challenging problem for crystal- lographers, mineralogists and petrologists. From the petrological point of view, interest in this field arose from the potential use of layer stacking data to furnish further informations about equilibrium and/or kinetic conditions prevailing during the crystallization of the widespread mica-bearing rocks. From the compilation of previous experimental works dealing with the occurrence domains of the various mica "polymorphs" (1Mr, 1M, 2M1, 2M2 and 3T) within water-pressure vs temperature fields, it became clear that most of these modifications should be considered as metastable for a fixed mica species. Furthermore, the natural occurrence of long-period (or complex) polytypes could not be accounted for by phase considerations. This highlighted the need of a more detailed kinetic approach of the problem and, in particular, of the role growth mechanisms of basal faces could play in this crystallographic phenomenon.

1. Introduction. Studies of radiation damage in ceramics are of interest not only from a fundamental point of view but also because it is important to understand the behavior of ceramics in various practical radiation enyironments- fission and fusion reactors, nuclear waste storage media, ion-implantation devices, outer space, etc. A great deal of work has been done on the spectroscopy of point defects and small defect clusters in ceramics, but relatively little has been performed on defect agglomeration using transmission electron microscopy (TEM) in the same kind of detail that has been so successful in metals. This article will assess our present understanding of radiation damage in ceramics with illustrations using results obtained from the authors' work.

Structural Aspects

Osmoregulatory mechanisms in algae were investigated mainly from a physiological point of view (KAUSS 1977, HELLEBUST 1976). In Porphyra two osmotic agents, i. e. floridoside/isofloridoside (KAUSS 1968) and certain ions, such as K+ and Na+(EPPLEY et al. 1960) are considered for osmotic balance. Accumulations of ions (particularly Na+) in the cytoplasm during osmotic adaptation is improbable, because the activity of enzymes is generally inhibited by high ionic concentrations (FLOWERS et al. 1977).The cellular organization of Porphyra was studied with special emphasis on the development of the vacuolar system under different hyperosmotic conditions. Porphyra was cultivated at various strengths of the culture medium ASP 12 (PROVASOLI 1961) ranging from normal to 6 times concentrated (6x) culture medium. Por electron microscopy freeze fracturing was used (specimens fixed in 2% glutaraldehyde and incubated in 30% glycerol, preparation in a BALZERS BA 360 M apparatus), because chemical fixation gave poor results.

Hardened Cement Paste

It has been almost universally adopted that dissolution of solids proceeds with development of uniform, continuous frontiers of reaction.However this point of view is doubtful / 1 /. E.g. we have proved the active role of the block (grain) boundaries in the main phases of cement, these boundaries being the areas of hydrate phases' nucleation / 2 /. It has brought to the supposition that the dissolution frontier of cement particles in water is discrete. It seems also probable that the dissolution proceeds through the channels, which serve both for the liquid phase movement and for the drainage of the incongruant solution products. These channels can be appeared along the block boundaries.In order to demonsrate it, we have offered the method of phase-contrast impregnation of the hardened cement paste with the solution of methyl metacrylahe and benzoyl peroxide. The viscosity of this solution is equal to that of water.
