ScienceDirect - International Journal of Pharmaceutics : Dendrimer toxicity: Let's meet... - 9 views

  •  
    Dendrimers are well-defined, versatile polymeric architecture with properties resembling biomolecules. Dendritic polymers emerged as outstanding carrier in modern medicine system because of its derivatisable branched architecture and flexibility in modifying it in numerous ways. Dendritic scaffold has been found to be suitable carrier for a variety of drugs including anticancer, anti-viral, anti-bacterial, antitubercular etc., with capacity to improve solubility and bioavailability of poorly soluble drugs. In spite of extensive applicability in pharmaceutical field, the use of dendrimers in biological system is constrained because of inherent toxicity associated with them. This toxicity is attributed to the interaction of surface cationic charge of dendrimers with negatively charged biological membranes in vivo. Interaction of dendrimers with biological membranes results in membrane disruption via nanohole formation, membrane thinning and erosion.

    Martin van Hemert is a photographer based in Utah. He is actively involved in architectural, product, and fine art photography. Throughout his career, he has consistently been drawn to more labor intensive forms of the art, from baking films in hydrogen for astronomical photography, to long exposures and light painting of outdoor scenes photographed on 4×5 sheet films, to his current obsession with spherical panoramas. Born to a family of Dutch immigrants, he studied music at the University of Utah, following which he made the logical choice of a career in photography. Martin and his wife are the parents of three grown children and one un-grown grandchild, and live in rural Utah County with a small herd of horses. Their rodent control staff boasts 7 members.

Insula (building) - Wikipedia, the free encyclopedia - 0 views

  • In Roman architecture, an insula (Latin for "island," plural insulae) was a kind of apartment building that housed most of the urban citizen population of ancient Rome, including ordinary people of lower- or middle-class status (the plebs) and all but the wealthiest from the upper-middle class (the equites). The traditional elite and the very wealthy lived in domus, large single-family residences, but the two kinds of housing were intermingled in the city and not segregated into separate neighborhoods.[1] The ground-level floor of the insula was used for tabernae, shops and businesses, with the living space upstairs. Like modern apartment buildings, an insula might have a name, usually referring to the owner of the building.[2]

Unbundling And Re-bundling In Higher Education - 15 views

  • With the explosion of online learning, a disruptive innovation, there has been significant attention paid to the likely unbundling of higher education (see Michael Staton’s AEI piece and this University Ventures Fund piece, for example). We’ve written about unbundling ourselves. In every industry, the early successful products and services often have an interdependent architecture—meaning that they tend to be proprietary and bundled. The reason for this is that when a technology is immature, in order to make the products reliable or powerful enough so that they will gain traction, an entity has to wrap its hands around the whole system architecture so that it can wring out every ounce of performance.

Google Art Project - 1 views

  •  
    The Art Project is a collaboration between Google and 151 acclaimed art partners from across 40 countries. Using a combination of various Google technologies and expert information provided by our museum partners, we have created a unique online art experience. Users can explore a wide range of artworks at brushstroke level detail, take a virtual tour of a museum and even build their own collections to share. With a team of Googlers working across many product areas we are able to harness the best of Google to power the Art Project experience. Few people will ever be lucky enough to be able to visit every museum or see every work of art they're interested in but now many more can enjoy over 30 000 works of art from sculpture to architecture and drawings and explore over 150 collections from 40 countries, all in one place. We're also lucky at Google to have the technology to make this kind of project a reality.

Can Architects Prevent Gun Deaths? | Smart News - 28 views

  • On Archinect, a discussion forum for architects, Peter Normand wondered what he could do to design spaces that reduced the chances of getting shot
  •  
    "Guns are on the minds of Americans. We're not sure if we should ban them, control them or give them away for free. Politicians are debating what we should do with them. Teachers are worrying how to keep them out of schools or how to train kids to respond. And architects wonder if they can design gunman-proof buildings. "

  • “The freshman year [as taught at traditional schools] should not exist,” Nelson says, suggesting that MOOCs can teach the basics. “Do your freshman year at home.”) Instead, Minerva’s first-year classes are designed to inculcate what Nelson calls “habits of mind” and “foundational concepts,” which are the basis for all sound systematic thought. In a science class, for example, students should develop a deep understanding of the need for controlled experiments. In a humanities class, they need to learn the classical techniques of rhetoric and develop basic persuasive skills. The curriculum then builds from that foundation.
  • What, he asks, does it mean to be educated?
  • methods will be tested against scientifically determined best practices
  • Subsidies, Nelson says, encourage universities to enroll even students who aren’t likely to thrive, and to raise tuition, since federal money is pegged to costs.

  • e traditional concept of “cognitive styles”—visual versus aural learners, those who learn by doing versus those who learn by studying—is muddled and wrong.

  • Its seminar platform will challenge professors to stop thinking they’re using technology just because they lecture with PowerPoint.
  • professors and students increasingly separated geographically, mediated through technology that alters the nature of the student-teacher relationship
  • The idea that college will in two decades look exactly as it does today increasingly sounds like the forlorn, fingers-crossed hope of a higher-education dinosaur that retirement comes before extinction.

Art of memory - Wikipedia, the free encyclopedia - 0 views

  • The Art of Memory or Ars Memoriae ("art of memory" in Latin) is a general term used to designate a loosely associated group of mnemonic principles and techniques used to organize memory impressions, improve recall, and assist in the combination and 'invention' of ideas. An alternative and frequently used term is "Ars Memorativa" which is also often translated as "art of memory" although its more literal meaning is "Memorative Art". It is sometimes referred to as mnemotechnics.[1] It is an 'art' in the Aristotelian sense, which is to say a method or set of prescriptions that adds order and discipline to the pragmatic, natural activities of human beings.[2] It has existed as a recognized group of principles and techniques since at least as early as the middle of the first millennium BCE,[3] and was usually associated with training in rhetoric or logic, but variants of the art were employed in other contexts, particularly the religious and the magical. Techniques commonly employed in the art include the association of emotionally striking memory images within visualized locations, the chaining or association of groups of images, the association of images with schematic graphics or notae ("signs, markings, figures" in Latin), and the association of text with images. Any or all of these techniques were often used in combination with the contemplation or study of architecture, books, sculpture and painting, which were seen by practitioners of the art of memory as externalizations of internal memory images and/or organization.

    The suburb of Saffron Park lay on the sunset side of London, as red and ragged as a cloud of sunset. It was built of a bright brick throughout; its sky-line was fantastic, and even its ground plan was wild. It had been the outburst of a speculative builder, faintly tinged with art, who called its architecture sometimes Elizabethan and sometimes Queen Anne, apparently under the impression that the two sovereigns were identical. It was described with some justice as an artistic colony, though it never in any definable way produced any art. But although its pretensions to be an intellectual centre were a little vague, its pretensions to be a pleasant place were quite indisputable. The stranger who looked for the first time at the quaint red houses could only think how very oddly shaped the people must be who could fit in to them. Nor when he met the people was he disappointed in this respect. The place was not only pleasant, but perfect, if once he could regard it not as a deception but rather as a dream. Even if the people were not "artists," the whole was nevertheless artistic. That young man with the long, auburn hair and the impudent face-that young man was not really a poet; but surely he was a poem. That old gentleman with the wild, white beard and the wild, white hat-that venerable humbug was not really a philosopher; but at least he was the cause of philosophy in others. That scientific gentleman with the bald, egg-like head and the bare, bird-like neck had no real right to the airs of science that he assumed. He had not discovered anything new in biology; but what biological creature could he have discovered more singular than himself? Thus, and thus only, the whole place had properly to be regarded; it had to be considered not so much as a workshop for artists, but as a frail but finished work of art. A man who stepped into its social atmosphere felt as if he had stepped into a written comedy.

Göbekli Tepe - Pictures, More From National Geographic Magazine - 67 views

  • The Birth of ReligionWe used to think agriculture gave rise to cities and later to writing, art, and religion. Now the world’s oldest temple suggests the urge to worship sparked civilization.
  • Before them are dozens of massive stone pillars arranged into a set of rings, one mashed up against the next. Known as Göbekli Tepe (pronounced Guh-behk-LEE TEH-peh), the site is vaguely reminiscent of Stonehenge, except that Göbekli Tepe was built much earlier and is made not from roughly hewn blocks but from cleanly carved limestone pillars splashed with bas-reliefs of animals—a cavalcade of gazelles, snakes, foxes, scorpions, and ferocious wild boars. The assemblage was built some 11,600 years ago, seven millennia before the Great Pyramid of Giza. It contains the oldest known temple. Indeed, Göbekli Tepe is the oldest known example of monumental architecture—the first structure human beings put together that was bigger and more complicated than a hut. When these pillars were erected, so far as we know, nothing of comparable scale existed in the world.
  • At the time of Göbekli Tepe's construction much of the human race lived in small nomadic bands that survived by foraging for plants and hunting wild animals. Construction of the site would have required more people coming together in one place than had likely occurred before. Amazingly, the temple's builders were able to cut, shape, and transport 16-ton stones hundreds of feet despite having no wheels or beasts of burden. The pilgrims who came to Göbekli Tepe lived in a world without writing, metal, or pottery; to those approaching the temple from below, its pillars must have loomed overhead like rigid giants, the animals on the stones shivering in the firelight—emissaries from a spiritual world that the human mind may have only begun to envision.

  • Archaeologists are still excavating Göbekli Tepe and debating its meaning. What they do know is that the site is the most significant in a volley of unexpected findings that have overturned earlier ideas about our species' deep past. Just 20 years ago most researchers believed they knew the time, place, and rough sequence of the Neolithic Revolution—the critical transition that resulted in the birth of agriculture, taking Homo sapiens from scattered groups of hunter-gatherers to farming villages and from there to technologically sophisticated societies with great temples and towers and kings and priests who directed the labor of their subjects and recorded their feats in written form. But in recent years multiple new discoveries, Göbekli Tepe preeminent among them, have begun forcing archaeologists to reconsider. At first the Neolithic Revolution was viewed as a single event—a sudden flash of genius—that occurred in a single location, Mesopotamia, between the Tigris and Euphrates Rivers in what is now southern Iraq, then spread to India, Europe, and beyond. Most archaeologists believed this sudden blossoming of civilization was driven largely by environmental changes: a gradual warming as the Ice Age ended that allowed some people to begin cultivating plants and herding animals in abundance. The new research suggests that the "revolution" was actually carried out by many hands across a huge area and over thousands of years. And it may have been driven not by the environment but by something else entirely.
  • Most of the world's great religious centers, past and present, have been destinations for pilgrimages
  • Göbekli Tepe may be the first of all of them, the beginning of a pattern. What it suggests, at least to the archaeologists working there, is that the human sense of the sacred—and the human love of a good spectacle—may have given rise to civilization itself.
  • n the 1960s archaeologists from the University of Chicago had surveyed the region and concluded that Göbekli Tepe was of little interest. Disturbance was evident at the top of the hill, but they attributed it to the activities of a Byzantine-era military outpo
  • To Schmidt, the T-shaped pillars are stylized human beings, an idea bolstered by the carved arms that angle from the "shoulders" of some pillars, hands reaching toward their loincloth-draped bellies. The stones face the center of the circle—as at "a meeting or dance," Schmidt says—a representation, perhaps, of a religious ritual. As for the prancing, leaping animals on the figures, he noted that they are mostly deadly creatures: stinging scorpions, charging boars, ferocious lions. The figures represented by the pillars may be guarded by them, or appeasing them, or incorporating them as totems.
  • nches below the surface the team struck an elaborately fashioned stone. Then another, and another—a ring of standing pillars.
  • Geomagnetic surveys in 2003 revealed at least 20 rings piled together, higgledy-piggledy, under the earth.
  • he pillars were big—the tallest are 18 feet in height and weigh 16 tons. Swarming over their surfaces was a menagerie of animal bas-reliefs, each in a different style, some roughly rendered, a few as refined and symbolic as Byzantine art.
  • The circles follow a common design. All are made from limestone pillars shaped like giant spikes or capital T's.
  • They hadn't yet mastered engineering." Knoll speculated that the pillars may have been propped up, perhaps by wooden posts.
  • Within minutes of getting there," Schmidt says, he realized that he was looking at a place where scores or even hundreds of people had worked in millennia past.
  • Puzzle piled upon puzzle as the excavation continued. For reasons yet unknown, the rings at Göbekli Tepe seem to have regularly lost their power, or at least their charm. Every few decades people buried the pillars and put up new stones—a second, smaller ring, inside the first.
  • he site may have been built, filled in, and built again for centuries.
  • Bewilderingly, the people at Göbekli Tepe got steadily worse at temple building.
  • Finally the effort seems to have petered out altogether by 8200 B.C. Göbekli Tepe was all fall and no rise.
