Climate change is a major challenge facing modern society. The chemistry of air and its influence on the climate system forms the main focus of this book. Vol. 2 of Chemistry of the Climate System takes a problem-based approach to presenting global atmospheric processes, evaluating the effects of changing air compositions as well as possibilities for interference with these processes through the use of chemistry.

Gerrie Radlof se gewilde Oloff die Seerowerreeks is oorspronklik tussen 1957 en 1961 uitgegee en het daarna reeds vier uitgawes beleef. Die verhale, wat in die 1740's afspeel aan die Kaap de Goede Hoop en die seewee daarom heen, is verwerk om aan te pas by die moderne taalgebruik en aan te sluit by die hedendaagse tiener, maar niks van die oorspronklike sjarme en spanning het in die verwerking verlore gegaan nie. Ook geskik as leesstof vir Afrikaans tweede taal vir ouer leerlinge.

This volume collects numerous recent advances in the study of stratified fluids. It includes analytical and experimental work from a wide range of fields, including meteorology, limnology, oceanography, and the study of estuarine processes. It also includes fundamental research on stratified and rotating fluid dynamics. A compendium of current work, the book is an ideal starting point for future research.

The conditions of our overpopulated planet with ever-growing energy needs, fossil fuels in limited supplies, and inefficient energy use world-wide, are creating a global crisis. Science has a responsibility, as well as a grand opportunity, to solve these energy-based problems of society. Science's new nanotechnologies, and the creativity they bring, are particularly appropriate to solve these problems. For example, energy-saving lighting, coupled with improved harvesting and conversion of sunlight into electric energy, will have a great impact on society's energy needs. Also, development of energy efficient and low cost fuel cells, which could eventually replace car engines, has a potential to improve everyday life greatly. Nanomaterials offer an opportunity to develop new low-cost materials as environmentally friendly solutions and renewable energy sources, in order to meet society's energy needs. Fortunately, a wide spectrum of the scientific community has become interested in developing these nanomaterials in order to solve the above energy challenges. Nanomaterials offer unique mechanical, catalytic, electronic, and optical features, which are different from those of the analogous bulk material (1). This is because nanomaterials have scale-dependent properties, due to quantum size effects, which means the nanomaterial size (10 - 100 nm) is smaller than the mean free path of their electrons. Thus, nanomaterials have great promise for use in harvesting solar energy, hydrogen production and storage, fuel cells, catalysis, chemical, optical sensors, drug delivery systems (such as liposomes), and nanothermite reactions (2-4). Fluorine-containing nanomaterials generally have certain unique properties which are often improved relative to the analogous non-fluorinated nanomaterials, and which therefore could be engineered. Although fluorine has the highest electronegativity of all the elements, which means that bonds to fluorine are generally quite polar, it is also in the second period of the periodic table, so it also has a small atomic radius and forms strong bonds. This produces the following properties, which also are characteristic of and bring great advantages to fluorine nanomaterials: high thermal and chemical stability, resistance to degradation by solvents, low flammability, low moisture absorption, low surface tension or energy, low dielectric constant, and serving as a strong oxidant under high energy conditions (5). However, little attention has been given to fluorine-containing organic and inorganic nanomaterials, which are predicted to have these unusual characteristics. This book presents examples of four diverse classes of these nanomaterials.

In 1923, Kansas governor Johnathan Davis traveled to Hutchinson to dedicate Emerson Careyas new rock salt mine whose shaft provided access to an ancient salt bed 650 feet under the earthas surface. The Carey Salt Mine, advertised as athe most modern in the world, a served as a companion to Careyas already-existing evaporation plants. Miners used the newest technology to blast and crush the mineral into gravel and haul it to the surface to provide rock salt for livestock, industries, and roads. Throughout the 20th century, thousands visited Careyas mining operations. Ever since the day Governor Davis presided over the opening ceremony, the Carey Salt Mine has served as a landmark for Hutchinson and helped shape its identity as athe Salt City.a

Today’s tech platforms are some of history's most advanced tools for extracting as much as possible – data, attention, profit-margins – from everyone else. As they become essential, we are at risk of building an economy that is perpetually unfair for much of humanity.

Places and spaces where people can exchange information and goods have been at the heart of every economy and every civilization in history, but today’s global platforms - as provided by Amazon, Google, Apple, Meta and others - are different: instead of providing value they extract it, creating vast disparities in wealth and power between the haves and have-nots. For the first time in history, we have the ability to create sustainable prosperity for all, but currently that wealth is concentrated in a tiny number of hands. It isn't abundance that's the problem; it is distribution.

In this brilliantly engaging, frequently surprising account, Tim Wu, one of the world’s foremost experts on anti-monopoly law, draws on fascinating case studies in the history of technology's explosive rise to demonstrate emphatically that breaking monopolies will ultimately unleash creativity and growth - and reduce the vast inequality that inevitably leads to social upheaval and political chaos. Wu also sets out an alternative blueprint that preserves the economic flourishing that platforms catalyze, allowing tech platforms to play a major role in creating and sustaining an economic model of prosperity not just for the few but for the many.

On Listening is a unique collection of forty multi-disciplinary perspectives drawn from anthropology, bioacoustics, geography, literature, community activism, sociology, religion, philosophy, art history, conflict mediation and the sonic arts including music, ethnomusicology and field recording. These specially commissioned contributions explore the many ways in which skilled listening can mediate new relationships with our physical environment and the people and other species that we share it with. From the Introduction: Listening has become an increasingly popular subject of study. It features in conferences, in academic journals, in doctoral research projects. However, reflexive listening is an applied practice that exceeds the boundaries of academic institutions to take its place in a number of everyday settings. This book aims to connect the scholarly and the experiential and extend the contemporary discourse on listening.

A rich fund of anecdotes drawn from the authora s time as an airline pilot and manager which spanned a forty year career, starting in the 1960s. Roughly tracing the authora s career, each story paints a different picture, be it be of a pilot, his faults and foibles, an experience the author had, a management problem and more. The backdrop is aviation but many of these stories could just as easily be transposed to a different setting. Most, but not all, have a strong flavour of humour and/or irony running through them. In todaya s world of political correctness and in a society otherwise constrained by litigious lawyers and an overbearing press many of these [mostly amusing] stories almost defy belief. Such has the world, and the world of aviation, moved on, few of the present crop of young pilots flying today would believe what went on behind closed doors. And neither would the rest of us!
