INSPIRATIONS OF NATURE IN ARCHITECTURE. BIONIC PAVILIONS. The search for bionics is an interesting design notion, where the form of architectural objects is not only inspired by the aesthetics or patterns found in nature, but how its shape is reproduced by the natural processes of morphogenesis. Depending on how various patters in nature are replicated, a number of bionic modeling can be observed. The design based on the principles of forming natural structures requires some understanding of the ongoing processes and their changes. Thanks to the improvement of generative design methods allowing for the advanced knowledge in the field of technology to build the individual structural elements, a structural replication and analysis of biological processes is possible. The creation of mathematical models is an attempt to describe the forms found in the natural world, in particular the aspects of the morphogenesis. The Voronoi diagrams, or the Fibonacci sequence, which are increasingly used as a method of the discretization of the surface, deserve special consideration among the mentioned patterns found in nature. Digital tools play an important role in this process through the application of appropriate algorithms and advanced computer programs, but also experimental activities geared to building prototype solutions. The design of complicated spatial forms under different aspects is also aimed at searching for optimized technical and material solutions, in which unnecessary geometry is being eliminated. The transfer of biological models into architecture also applies to functional processes and systems found in nature in terms of shaping the coating elements. This paper is dedicated to the presentation of the completed experimental pavilions, which were created based on the bionic ideas, where the search for the multifunctional materials seems to be particularly important and could in turn revolutionize the building industry.

In this article I shall compare and contrast Ibn Khaldun’s ideas aboutsociohistorical change with those of Hegel, Marx, and Durkheim. I willdiscuss and elaborate Ibn Khaldun’s major ideas about historical andsocial change and compare them with three important figures of modemWestern sociology and philosophy.On reading Ibn Khaldun one should remember that he was living in thefourteenth century and did not have the privilege of witnessing the socialdislocation created by the industrial revolution. It is also very difficult tocategorize Ibn Khaldun within a single philosophical tradition. He is arationalist as well as an empiricist, a historicist as well as a believer inhuman agency in the historical process. One can see many “modem”themes in his thinking, although he lived a hundred years beforeMachiavelli.Lauer, who considers Ibn Khaldun the pioneer of modem sociologicalthought, has summarized the main points of his philosophy.’ In his interpretationof Ibn Khaldun, he notes that historical processes follow a regularpattern. However, whereas this pattern shows sufficient regularity, itis not as rigid as it is in the natural world. In this regard the position ofIbn Khaldun is radically different from those philosophies of history thatposit an immutable course of history determined by the will of divineprovidence or other forces. Ibn Khaldun believes that the individual isneither a completely passive recipient nor a full agent of the historicalprocess. Social laws can be discovered through observation and datagathering, and this empirical grounding of social knowledge represents adeparture from traditional rational and metaphysical thinking ...

The fine structure of the tapetum of the cat eye has been investigated by electron microscopy. The tapetum is made up of modified choroidal cells, seen as polygonal plates grouped around penetrating blood vessels which terminate in the anastomosing capillary network of the choriocapillaris. The tapetal cells are rectangular in cross-section, set in regular brick-like rows, and attain a depth of some thirty-five cell layers in the central region. This number is gradually reduced peripherally, and is replaced at the margin of the tapetum by normal choroidal tissue. The individual cells are packed with long slender rods 0.1 µ by 4 to 5 µ. The rods are packed in groups and with their long axes oriented roughly parallel to the plane of the retinal surface. Each cell contains several such groups. Cells at the periphery or in the outer layers of the tapetum are frequently seen to contain both tapetal rods and melanin granules, the latter typical of the choroidal melanocytes. Also melanocyte granules may have intermediate shapes. These observations plus the similar density of the two inclusions lead to the belief that the tapetal rods may be melanin derivatives. A fibrous connective tissue layer lies between the tapetum and the retina. The subretinal capillary network, the choriocapillaris, rests on this layer and is covered by the basement membrane of the retinal epithelium. The cytoplasm of the retinal epithelium exhibits marked absorptive modifications where it comes in contact with the vessels of the choriocapillaris. This fibrous layer and the basement membrane of the retinal epithelium apparently comprise the structural elements of Bruch's membrane.

The individual employs two basic sources for perception: direct experience and the interpretations of the culture. Natural processes can lead individuals who seek to resolve problems together to excessive reliance on socialized perceptions while overlooking valuable direct experience. As the partners establish assumptions, they may prematurely cease the search for information which could lead to a new perspective on the problem. A cycle is mobilized in which information generated by direct encounter fails to check powerful assumptions. The authors offer an observational model through which partners share both their experiences and their interpretations of these experiences. The model is designed to reduce the power of assumptions and to restore the influence of direct experience in problem resolution.

While the terms ‘aesthetics’ and ‘philosophy’ were only introduced into Japan during the Meiji Period (post 1868), Japanese culture has nevertheless witnessed the proliferation of various arts and theories of art for over a millenium. Given that ‘aesthetics’ generally connotes a scientific, often taxonomic approach to the inquiry into beauty and art, it may be preferable to consider Japanese art and theories of art from the perspective of different ways of artistry, rather than impose on it alien categories and assumptions. Even our understanding about what constitutes art must alter when we consider such arts as the production of incense, the tea ceremony, the martial arts or flower arrangement, most of which do not have precise analogues in the West; or if they do, are not considered arts alongside poetry, drama, music and painting. One of the hallmarks of Japanese art is the emphasis on an awareness of nature. Not only is the natural world a rich storehouse of images and metaphors for use as subject matter, but it is also the means whereby the practices, values and aspirations of the art are defined. Significantly, art itself is seen to be catalysed directly by an encounter with the natural world. All living beings, we are told, are given to song. Yet the natural world also came to be a shibboleth in society among the members of the Japanese court, where a finely honed seasonal awareness came to attest to the refinement and sensibility of the individual. Of all the arts, poetry was seen as pre-eminent, in part because of poetry’s powers to influence the spirits inherent in the natural world. Even the emphasis on place and place-names in Japanese art may be traced to an understanding of the Japanese landscape and language as sacredly imbued. Another feature of Japanese art and theories of art is its orientation toward the human. In other words, we may define Japanese art as ‘expressive–affective’ in its configuration, stressing the experience of the artist as well as the response of the audience in encountering such a work. In fact, the two roles of artist and audience are related through the focus of the work of art, which usually frames a single moment and its quintessential significance, hon-i, which is unchanging. The quality which ideally characterizes both artist and audience is makoto or sincerity, underlining the point that the function of most Japanese art is to make us feel, rather than think. As in a number of other traditions, Japanese ways of art are bound up inextricably with issues of religion and religious practice. Not only did Shintō animatism have a profound impact on how Japanese viewed their landscape as well as their own lives, but other imported systems of belief also influenced the course of artistic development, especially Buddhism. Buddhism darkened the hues of classical Japanese art by introducing ideas such as mappō (Latter Days of the Law), which saw the present as degraded and corrupt with respect to the past, and mujō (inconstancy), or the awareness of the ephemerality of this phenomenal world. In Mahāyāna Buddhism, art was perceived as a means of religious awakening, both in the case of poetry viewed as a form of intense meditation (shikan) and as parables whereby the truth could be disseminated obliquely (hōben). This paved the way for the pursuit of various forms of art to become a path (michi) to spiritual awareness. The relation of teacher and student in an art form closely resembled the relation of spiritual master to disciple, a feature which is echoed in the various ‘secret’ artistic treatises whose form, approach and significance suggest esoteric Buddhist manuals setting forth precepts for future generations. Japanese theories of art also concerned themselves with various aesthetic ideals, distillations of the changing notion of beauty in each era. From aware (the beauty inherent in transience) and miyabi (courtly beauty) during the Heian Period (784–1185), to yūgen (the beauty of mystery and overtones) and sabi (the beauty of desolation and loneliness) in the medieval period, finally to wabi (the beauty of dearth and the humble) and karumi (the beauty of playful lightness) during the Edo Period (1600–1868), to mention only a few of the many ideals, we see an evolution of ideals as a response to cultural and historical change. What becomes evident in any survey is the assumption of an underlying unity, as in the notions that the impulse toward art is natural and universal; that art functions as a bridge mediating the experience of artist and audience; that sincerity and heart are to be privileged above all other qualities; and that the discipline of art can be a means of spiritual awakening. But we also discover that ideas, such as play, are critical to all forms of art in Japan. Other issues have surfaced periodically in various art forms in the course of Japanese history, such as the struggle between tradition and innovation or the debate about art as spontaneous versus art as the product of careful cultivation (that is, the question of artifice in art), or the question of the singularity of Japanese art.

INTRODUCTION Density, public health and safety, quality of life, and sustainability are some of the most confounding issues that major cities face today as they expand in population and area. How do we bring urban populations closer together in the public realm, while still providing space for the individual psyche and also increasing the overall sense of positive connection to the natural world and to each other? Robust natural landscapes have sometimes been considered a luxury within a functioning city, but more and more they are being recognized for the vital role they play in making cities livable. The story of Corktown Common relates how a landscape built of necessity was also designed to deliver myriad public benefits, including enhanced urban ecology and sustainability.

Self-recognition is observed abundantly throughout the natural world, regulating diverse biological processes. Although ubiquitous, often little is known of the associated molecular machinery, and so far, organismal self-recognition has never been described in nematodes. We investigated the predatory nematode Pristionchus pacificus and, through interactions with its prey, revealed a self-recognition mechanism acting on the nematode surface, capable of distinguishing self-progeny from closely related strains. We identified the small peptide SELF-1, which is composed of an invariant domain and a hypervariable C terminus, as a key component of self-recognition. Modifications to the hypervariable region, including single–amino acid substitutions, are sufficient to eliminate self-recognition. Thus, the P. pacificus self-recognition system enables this nematode to avoid cannibalism while promoting the killing of competing nematodes.

AbstractAutomated extraction of quantitative linguistic features has the potential to predict objectively the onset and progression of psychosis. These linguistic variables are often considered to be biomarkers, with a large emphasis placed on the pathological aberrations in the biological processes that underwrite the faculty of language in psychosis. This perspective offers a reminder that human language is primarily a social device that is biologically implemented. As such, linguistic aberrations in patients with psychosis reflect both social and biological processes affecting an individual. Failure to consider the sociolinguistic aspects of NLP measures will limit their usefulness as digital tools in clinical settings. In the context of psychosis, considering language as a biosocial marker could lead to less biased and more accessible tools for patient-specific predictions in the clinic.

RNA pseudoknots are structural elements found in almost all classes of RNA. Pseudoknots form when a single-stranded region in the loop of a hairpin base-pairs with a stretch of complementary nucleotides elsewhere in the RNA chain. This simple folding strategy is capable of generating a large number of stable three-dimensional folds that display a diverse range of highly specific functions in a variety of biological processes. The present review focuses on pseudoknots that act in the regulation of protein synthesis using cellular and viral examples to illustrate their versatility. Emphasis is placed on structurally well-defined pseudoknots that play a role in internal ribosome entry, autoregulation of initiation, ribosomal frameshifting during elongation and trans-translation.

This chapter articulates the LOHAS vision of health as a three-part holistic model of self, society, and the natural world. In turn, “holistic” has been described in LOHAS more through Eastern perspectives rather than Western religious traditions in that it presupposes a state of interconnectedness of all phenomena—mind and matter, animal and human, global cultures and ecosystems. For example, the holistic worldview of Buddhism (a frequently called-upon tradition in LOHAS literature), understands that interdependence means that “humanity is only one actor” in the environment and that all actors must remain in balance for the system to be healthy. But this flies in the face of late consumer culture, where the individual reigns supreme, and where LOHAS is predominantly lodged. The final section examines how that problem is overcome, how Mother Nature becomes intertwined with the healed self as part of the healing and a vital component of the model of holistic health. It shows how healing the self becomes exonerated from the “narcissism” of the New Age and instead becomes reframed as the stepping stone to a collective good, capable of initiating global transformation based on the notion of holistic health.
