History And Theory

This project has investigated African graphic systems, both writing systems and systems of symbolic graphics. These systems are commonly used in Graphic Design, but those of African origin have been largely ignored in both the applied discipline, and in its History and Theory. The project has attempted to explain this in historical and theoretical terms: its motivation is described in terms of countering the exclusion of African visual culture in the face of historical and ideological factors such as colonialism and globalisation. The project's research aims were to collect as much information as feasible on these systems; and to classify them according to such criteria as their language or cultural group, their location, and the functional nature of the systems. From this body of information a smaller number of representative systems were selected for further description and discussion, in order to highlight the variety of systems existing in Africa, their historical development, and techniques and materials used. These selected systems were then used as inspiration and raw material for a body of applied Graphic Design work, which is intended to provide a visual introduction to the material, and to promote and advocate the revaluation of this cultural material. Information has mainly been gathered by means of library and internet search, in order to establish approximately the extent of the literature in the public sphere. Because of the obscurity of most of this information, it has been gathered from such other disciplines as Linguistics, Anthropology, or History. The project has established the existence of a large number of graphic symbols and systems, and gathered a body of literature and references about them. Many are poorly documented, if at all, and even those for which extensive literature

The Public Sphere

In July 2010, Terry Jones, the pastor of a small fundamentalist church in Florida, announced plans to burn two hundred Qur'ans on the anniversary of the September 11 attacks. Though he ended up canceling the stunt in the face of widespread public backlash, his threat sparked violent protests across the Muslim world that left at least twenty people dead. This book demonstrates how the beliefs of fanatics like Jones are inspired by a rapidly expanding network of anti-Muslim organizations that exert profound influence on American understanding of Islam. The book traces how the anti-Muslim narrative of the political fringe has captivated large segments of the American media, government, and general public, validating the views of extremists who argue that the United States is at war with Islam and marginalizing mainstream Muslim-Americans who are uniquely positioned to discredit such claims. Drawing on cultural sociology, social network theory, and social psychology, the book shows how anti-Muslim organizations gained visibility in the public sphere, commandeered a sense of legitimacy, and redefined the contours of contemporary debate, shifting it ever outward toward the fringe. The book illustrates the author's pioneering theoretical argument through a big-data analysis of more than one hundred organizations struggling to shape public discourse about Islam, tracing their impact on hundreds of thousands of newspaper articles, television transcripts, legislative debates, and social media messages produced since the September 11 attacks. The book also features in-depth interviews with the leaders of these organizations, providing a rare look at how anti-Muslim organizations entered the American mainstream.

Magazine Cover

Magazine is one of the forms of mass media that has fungsikomunikasi to convey information to mass audiences. The cover is an important element because it is through cover / cover one can guess the contents of the magazine, as well as further interested to know further information contained therein. On a magazine cover consists of drawings and writings are arranged in such a way that looks interesting and has meaning Press publications, especially magazines, today's not enough just to rely on the quality of news or manuscript, although verbal aspect is very important. It must be recognized that the visual aspects (design) as the cover / envelope has crucial role to capture the prospective reader. For the cover of a magazine is a window that shows the content information, can be either a text or photographs, illustrations, and design elements. The function of a magazine cover is to attract, dazzle prospective readers, by way influence the thoughts flow in a short time. So it's no wonder much current the magazine publisher who made the cover of such a way as to attract the attention of prospective readers. Thus the task of designers to magazine cover to create designs that attract the attention of the reader becomes increasingly severe. This study tries to analyze a visual on the front cover Magazine Graphic Design 'Concept' birthday inaugural edition by using the Roland Barthes' semiotic approach. As Roland Barthes (1984), any simple "design work (magazine cover)" continue to play in management of the sign. So that will generate a message (image) specific. Design cover, usually contains the elements of the sign in the form of objects, context of the environment, people or other beings who provide meaning to objects, and text (of writing) that reinforce the meaning.Keyword: cover, magazine Concept, semiotics

Phenol–formaldehyde (PF) resin continues to dominate the resin industry more than 100 years after its first synthesis. Its versatile properties such as thermal stability, chemical resistance, fire resistance, and dimensional stability make it a suitable material for a wide range of applications. PF resins have been used in the wood industry as adhesives, in paints and coatings, and in the aerospace, construction, and building industries as composites and foams. Currently, petroleum is the key source of raw materials used in manufacturing PF resin. However, increasing environmental pollution and fossil fuel depletion have driven industries to seek sustainable alternatives to petroleum based raw materials. Over the past decade, researchers have replaced phenol and formaldehyde with sustainable materials such as lignin, tannin, cardanol, hydroxymethylfurfural, and glyoxal to produce bio-based PF resin. Several synthesis modifications are currently under investigation towards improving the properties of bio-based phenolic resin. This review discusses recent developments in the synthesis of PF resins, particularly those created from sustainable raw material substitutes, and modifications applied to the synthetic route in order to improve the mechanical properties.

Consequent Increase

Dental implants are becoming increasingly used in current dental practice. This increased demand has motivated manufacturers to develop varieties of product through design, but also looking for new materials used to improve surface characteristics in order to obtain a better osseointegration. But the increase in the use of implants goes to a consequent increase in the number of failures. These failures are caused either by treatment complications (peri-implantitis), by fatigue breakage under mechanical over-stress, by defective raw material, or due to errors during the insertion procedures. Although they are rare, these complications are serious in dentistry. Before to market a dental implant to clinical practitioners, the product is validated among other determinations in number of biocompatibility research. Raw material issues, details about its structure and properties are less published by the scientific literature, but all this are subject of a carefully analysis of the producers. Breaking of dental implants during surgical procedures, during the prosthetic procedures or during use (chewing, bruxism, accidents, etc.), is the second most common cause of loss of an implant after consecutive peri-implantitis rejection. Although the frequency of this type of failure for a dental implant is much smaller than those caused by the peri-implantitis, a detailed study of broken implants can explain possible causes. The use of scanning electron microscopy (SEM) in the study of the cleave areas explain the production mechanism of cleavages, starting from micro-fissures in the alloy used for the production of dental implants. These micro-fissures in weak areas of the implant (anti-rotational corners of the polygons, etc.) could generate a serious risk of cleavage first time when a higher force is applied.

Aesthetic Awareness

Art of animation as an analysis of movement is based on the theory that the vision remains on the eye after the disappearance of the actual image, and this scientific theory is the same that the film industry was built upon. Recently, various techniques and ideas have entered the print design process as a means of expressing a phenomenon subject to the human will to change and elevate our aesthetic awareness and feelings, which rise in various forms of designs that reveal themselves in design work and are embodied in animation films. The design artwork falls within a group of intertwined elements fused with each other, reflecting the peculiarity of this work, as it is innovation and creating new and interesting things, so that the design is suitable for the desired purpose and beautifully. Perhaps the simplest type of optical illusion that can clarify to us the idea of the impression of the existence of an image that does not actually exist is represented in the decree paper.

The sugarcane industry generates huge amounts of sugarcane bagasse ashes (SCBA). This work investigates the incorporation of a SCBA waste as an alternative raw material into a clay body, replacing natural clay material by up to 20 wt.%. Clay ceramic pieces were produced by uniaxial pressing and fired at temperatures varying from 700 to 1100 ºC. The technological properties of the clay ceramic pieces (linear shrinkage, apparent density, water absorption, and tensile strength) as function of the firing temperature and waste addition are investigated. The phase evolution during firing was followed by X-ray diffraction. The results showed that the SCBA waste could be incorporated into red ceramics (bricks and roofing tiles) in partial replacement for natural clay material. These results confirm the feasibility of valorisation of SCBA waste to produce red ceramic. This use of SCBA can also contribute greatly to reducing the environmental problems of the sugarcane industry, and also save the sources of natural raw materials used in the ceramic industry.

The Cost

The replacement of conventional materials used in hot asphalt mixtures with others of good technique and lower cost and environmental impact has motivated research in this area of knowledge in recent decades. The researches should be expanded in the scope of engineering, given that it contributes considerably to the transformation of spaces and raw material. In this context, thermoelectric ashes, which are residues from the production of electric energy, appear as an alternative to replace the stone powder input which contributes negatively to the environment considering that it comes from the blasting of rocks. This work aims to compare the cost of producing traditional asphalt concrete (reference) to asphalt compositions containing 5,15% of alternative material characterized by stone dust. There was a saving of R$ 0.21 per ton of AC machining, consisting of thermoelectric ash as a partial substitute (5.15%) for stone powder, which represents significant savings in a practical context.

The City

&lt;p&gt;The city of &amp;#201;vora, a World Heritage Site recognized by UNESCO in 1986, also owes this recognition to the stones that built its monuments and preserve them until today.&lt;/p&gt;&lt;p&gt;This work brings together the contributions that we have gathered over the past three decades and allow us to have a very complete idea, not only about the materials used in the hundreds of monuments and historic buildings but also about their provenance. If some materials are so emblematic that they allow an immediate identification with the naked eye, others needed more sophisticated and precise techniques so that there was no doubt about their origin.&lt;/p&gt;&lt;p&gt;The igneous rocks and gneisses of granite composition are part of the &amp;#8220;Massif of &amp;#201;vora&amp;#8221; on which the city is built. Thus, and quite naturally they are by far the most represented group in monuments from all historical periods. Its function is essentially structural, but there are also functional, ornamental and decorative objects. For example, the oldest megalithic structures found in the vicinity of the city are made up of large granite blocks that often had to be transported to their locations.&lt;/p&gt;&lt;p&gt;On the other hand, many gargoyles and statues that decorate the churches are also made up of these granite rocks. On these, the natural erosion of centuries of exposure to the environment has led to a state of alteration, sometimes very accentuated, which would justify its replacement by replicas sculpted in similar rocks. Provenance studies have made it possible to identify old quarries in the vicinity of the city where, on the one hand, the ancient rock extraction techniques can be observed and on the other hand, they allow the obtaining of the raw material necessary for these restoration and conservation works. In any case, they are places that need to be inventoried and protected, with the municipality already aware of their existence.&lt;/p&gt;&lt;p&gt;As well as the monuments of the Roman Period, also the structures of the Medieval Period, such as the city walls, the Cathedral (started to be built in 1186 AD) and all the great churches, were also built with these granitoids.&lt;/p&gt;&lt;p&gt;In addition to these rocks, many others of multiple varieties and origins are present. The marbles, especially the Estremoz Marbles (Global Heritage Stone Resource), are ubiquitous in the city, but there are also emblematic marbles from other places, some easily identifiable (ie Viana do Alentejo, Escoural, Trigaches, Serpa and Vila Verde de Ficalho, for presenting mineralogy, textures, colors and patterns which, together with more recent analytical techniques, have confirmed its provenance.&lt;/p&gt;&lt;p&gt;Sedimentary rocks, with emphasis on Portuguese Mesozoic limestones, ie Lioz - GHSR and Brecha da Arr&amp;#225;bida - GHSR candidate, among others more rare and with very specific use in ornamental details, are also present and contribute to enrich a heritage in stone that makes this city so special and very popular with tourists of all nationalities.&lt;/p&gt;&lt;p&gt;Acknowledgments: the authors thank to FCT for funding the ICT (UID/GEO/04683/2019), as well as COMPETE POCI-01-0145-FEDER-007690.&lt;/p&gt;

Loss Of Genetic Diversity

Genetic diversity provides the raw material for species to adapt and persist in the face of climate change. Yet, the extent to which these genetic effects scale at the level of ecological communities remains unclear. Here we experimentally test the effect of plant genetic diversity on the persistence of an insect food web under a current and future warming scenario. We found that plant genetic diversity increased food-web persistence by increasing the intrinsic growth rates of species across multiple trophic levels. This positive effect was robust to a 3°C warming scenario and resulted from allelic variation at two genes that control the biosynthesis of chemical defenses. Our results suggest that the ongoing loss of genetic diversity may undermine the persistence and functioning of ecosystems in a changing world.One Sentence SummaryThe loss of genetic diversity accelerates the extinction of inter-connected species from an experimental food web.
