Il testo si configura come un' introduzione alla fisica statistica rivolto in primo luogo a quei corsi di studio in ingegneria che più hanno a che fare con le proprietà fisiche dei materiali, ed ha lo scopo di fornire le basi microscopiche del comportamento termodinamico di cui si fa uso sia in molti corsi tradizionali, quali quelli di termofluidica d'interesse per l'ingegneria chimica e nucleare, che in corsi rivolti ad applicazioni avanzate nella scienza dei materiali e nelle nanotecnologie. Particolare attenzione viene quindi dedicata all'impiego di metodi di fisica statistica nella scienza dei materiali, approfondendo tematiche relative alle vibrazioni nei solidi, ai processi di nucleazione liquido/vapore, alla struttura dello stato fluido e vetroso, ai plasmi, ai materiali magnetici, al gas di Fermi e alla superfluidità. Per il suo carattere generale, e per l'accento posto sui fondamenti della meccanica quantistica, il volume si presta comunque a costituire anche un testo introduttivo alla meccanica statistica per studenti dei corsi di laurea in fisica.

In the twelfth century AD, Venice is little more than an agglomeration of small islands snatched from the muddy tides. The magnificent city-lagoon of Venice, the rich and powerful Serene Republic, is yet to be born. Here, in this northern backwater, a group of artisans have proven themselves to be unrivalled in an art form that produces works of such astounding beauty that many consider it mystical in nature and think its practitioners possessed of otherworldly gifts: glassmaking. Presciently aware of the power they wield and the role they will play in the Venice of the future, the Venetian glassmakers inhabit a world of esoteric practices and secret knowledge that they protect at all costs. Into this world steps Edgardo D'Arduino, a cleric and a professional copyist. Edgardo's eyesight has begun to wavera curse for a man who makes his living copying sacred texts. But he has heard stories, perhaps legends, that in Venice, city of glassmakers, there exists a stone, the la

In the wake of the Mexican-American War, competing narratives of religious conquest and re-conquest were employed by Anglo American and ethnic Mexican Californians to make sense of their place in North America. These “invented traditions” had a profound impact on North American religious and ethnic relations, serving to bring elements of Catholic history within the Protestant fold of the United States’ national history as well as playing an integral role in the emergence of the early Chicano/a movement. Many Protestant Anglo Americans understood their settlement in the far Southwest as following in the footsteps of the colonial project begun by Catholic Spanish missionaries. In contrast, Californios—Mexican-Americans and Chicana/os—stressed deep connections to a pre-Columbian past over to their own Spanish heritage. Thus, as Anglo Americans fashioned themselves as the spiritual heirs to the Spanish frontier, many ethnic Mexicans came to see themselves as the spiritual heirs to a southwestern Aztec homeland.

Since ancient times, mankind has used plants as a valuable source of natural products for maintaining human health and to treat or prevent diseases. The common knowledge around plants' healing properties, known as folk medicine, has been transmitted over the centuries for generations throughout human communities. The use of natural products and herbal medicines have been documented in the past. The antibacterial activity of plant extracts has been reported since the late 1800s and some of these traditional medicines are still used, especially in the last decade, with more intensive studies for natural therapies. Active compounds produced during vegetal metabolism are responsible for the antimicrobial and biological properties interacting with specific chemical receptors in the human body and, due to these components, plants extracts are popular as anti-inflammatory, anti-bacterial or anti-fungal drugs. However, in the absence of scientific studies, the use of aleatory plant extracts may lead to harmful adverse effects. Previously considered empirical, current data on the antimicrobial activity and biocompatibility of numerous plants have been scientifically confirmed. Phytosciences, as ethnopharmacology or phytotherapy, are emerging multidisciplinary areas with almost unlimited sources and several aspects to be discussed. Recently, there has been a growing trend to seek natural drugs as part of dental treatment. In dentistry, the association of plant extracts with restorative dentistry, endodontics or periodontics materials have been used to reduce inflammation, as antimicrobial enhancer agent, antiseptics, antifungals, antioxidants, analgesics or even as mouth rinse to prevent or reduce dental plaque. Thus, this book will address the use of plant extracts in different fields of dentistry, highlighting its use in cariology, restorative dentistry, endodontics and periodontics, besides other uses of herbal plants in dentistry, as in dental trauma, osteointegration or hemostatic, among others. As will be shown and stated, the vast variety of different plants described in literature with medicinal properties makes it impracticable to discuss all extracts found in scientific literature. Therefore, this book will contribute with some of these extracts and different methodologies to assess, as an introduction to new research and new researchers. Also, different in vivo and in vitro tests used to evaluate biological response, such as biocompatibility and antimicrobial activity in dental treatment will be discussed.

Though nothing in the natural world would be quite the same without them, microbes go mostly unnoticed. They are the tiny, mighty force behind the pop in Champagne and the holes in Swiss cheese, the granite walls of Yosemite and the white cliffs of Dover, the workings of snowmaking machines, Botox, and gunpowder; and yet we tend to regard them as peripheral, disease-causing, food-spoiling troublemakers. In this book renowned microbiologist John Ingraham rescues these supremely important and ubiquitous microorganisms from their unwonted obscurity by showing us how we can, in fact, see them—and appreciate their vast and varied role in nature and our lives.Though we might not be able to see microbes firsthand, the consequences of their activities are readily apparent to our unaided senses. March of the Microbes shows us how to examine, study, and appreciate microbes in the manner of a birdwatcher, by making sightings of microbial activities and thereby identifying particular microbes as well as understanding what they do and how they do it. The sightings are as different as a smelly rock cod, a bottle of Chateau d’Yquem, a moment in the Salem witch trials, and white clouds over the ocean. Together they summarize the impact of microbes on our planet, its atmosphere, geology, weather, and other organisms including ourselves, to whom they dole out fatal illnesses and vital nutrients alike.In the end, Ingraham leaves us marveling at the power and persistence of microbes on our planet and gives credence to Louis Pasteur’s famous assertion that “microbes will have the last word.”

The fish faunas of continental South and Central America constitute one of the greatest concentrations of aquatic diversity on Earth, consisting of about 10 per cent of all living vertebrate species. "Historical Biogeography of Neotropical Freshwater Fishes" explores the evolutionary origins of this unique ecosystem. The chapters address central themes in the study of tropical biodiversity: why is the Amazon basin home to so many distinct evolutionary lineages? What roles do ecological specialization, speciation, and extinction play in the formation of regional assemblages? How do dispersal barriers contribute to isolation and diversification? Focusing on whole faunas rather than individual taxonomic groups, this volume shows that the area's high regional diversity is not the result of recent diversification in lowland tropical rainforests. Rather, it is the product of species accumulating over tens of millions of years and across a continental arena.
