...HEAD | PREVIOUS | Chapter 1 Introduction 1.1 What is a Plasma? 1.1.1 An ionized gas A plasma is a gas in which an important fraction of the atoms is ionized, so that the electrons and ions are separately free. When does this ionization occur? When the temperature is hot enough. Balance between collisional ionization and recombination: | Figure 1.1: Ionization and Recombination Ionization has a threshold energy. Recombination has not but is much less probable. Threshold is ionization energy (13.6eV, H). χi | Figure 1.2: Ionization and radiative recombination rate coefficients for atomic hydrogen Integral over Maxwellian distribution gives rate coefficients (reaction rates). Because of the tail of the Maxwellian distribution, the ionization rate extends below T = χi. And in equilibrium, when | nionsnneutrals | = | < σi v >< σr v > | , | | (1.1) | the percentage of ions is large ( ∼ 100%) if electron temperature: Te >~χi/10. e.g. Hydrogen is ionized for Te >~1eV (11,600°k). At room temp r ionization is negligible. For dissociation and ionization balance figure see e.g. Delcroix Plasma Physics Wiley (1965) figure 1A.5, page 25. 1.1.2 Plasmas are Quasi-Neutral If a gas of electrons and ions (singly charged) has unequal numbers, there will be a net charge density, ρ. ρ = ne(−e) + ni(+e) = e (ni − ne) | | (1.2) | This will give rise to an electric field via ∇ .

...Badminton is a racquet sport played by either two opposing players (singles) or two opposing pairs (doubles), who take positions on opposite halves of a rectangular court that is divided by a net. Players score points by striking a shuttlecock with their racquet so that it passes over the net and lands in their opponents' half of the court. Each side may only strike the shuttlecock once before it passes over the net. A rally ends once the shuttlecock has struck the floor. The shuttlecock (or shuttle) is a feathered projectile whose unique aerodynamic properties cause it to fly differently from the balls used in most racquet sports; in particular, the feathers create much higher drag, causing the shuttlecock to decelerate more rapidly than a ball. Shuttlecocks have a much higher top speed, when compared to other racquet sports. Because shuttlecock flight is affected by wind, competitive badminton is played indoors. Badminton is also played outdoors as a casual recreational activity, often as a garden or beach game. Since 1992, badminton has been an Olympic sport with five events: men's and women's singles, men's and women's doubles, and mixed doubles, in which each pair consists of a man and a woman. At high levels of play, the sport demands excellent fitness: players require aerobic stamina, agility, strength, speed and precision. It is also a technical sport, requiring good motor coordination and the development of sophisticated racquet movements. HISTORY The beginnings...

...Traditional discussions around the architecture of business applications tend to focus on the application tier as being the connection between people and data and this holds for discussions around SOAs, Service Component Architectures (SCAs), or most other architectural perspectives in the industry today, including first-generation discussions around composite applications. Typically, however, the application tier contains structured business logic. However, building a composite application requires a mindset that not only is the productivity tier a critical element of the stack, but also it is where the most business value to enterprises can be found. To expand on the comparison between composite applications and SOA, both of them target flexibility and modularization. However, SOA provides flexibility at just one tier: that of the structured business logic in the middle tier. Composite applications target flexibility at all four tiers: presentation, productivity, application, and data. So, composite applications provide business value to the end users, in a way that goes far beyond what can be achieved with just service orientation. That said, a composite application is a great way to surface information out of a SOA, and having line-of-business (LOB) applications exposed as services makes it easier to build support for cross-functional processes into a composite application. Therefore to summarize, the ability to build and deploy composite applications requires a platform...

...They’d get out of this. They had to get out of this. My God, all his other fuckups were just preparations for this. This wasn’t possible. He could feel the current—strong, insistent, pumping against his thigh like a drunken lover. Was this how it went? One stupid move? One stupid fucking move, and your son on your back? No. He could do this. He tried to remember the strength he’d felt, that rude, beautiful strength, felt it pushing back the curtain of fear. There was nowhere to go. He could barely bring himself to speak. He couldn’t move. The way ahead was impossible. Far below, he could hear the water sucking on the shallow cavity made by his hip. The river. It wanted to be whole, unbroken. It wanted him gone. He could see it, forming and reforming, thick-walled jade, smoothing out its sides with its thumbs like a hypnotized potter. The water blurred. He wanted to scream for help. There was no one—just the rushing plain of the river, the trees. He couldn’t move. A muscle in his shoulder was jerking like a poisoned animal. What combination of things? Everything had come together. He couldn’t move. He was barely holding on. There was no way. The river ahead was smooth, deep, gliding over brown boulders trailing beards of moss in the deep wind. He wanted to laugh. For a second, he felt the hot, shameful fire of remorse and then unending pity—for himself, for the boy on his back, for the world—and at that moment he remembered hearing about a medieval priest who, personally taking...

...1. I chose a story about domesticating wild animals and its history that starts 30 to 40 thousand years ago. Link: http://www.theonion.com/article/study-humans-began-domesticating-animals-comfort-c-51391 2. The Onion`s argument is that people are domesticating wild animals, like wolves, in order to “comfort” children whose parents had separated. According to The Onion, our ancient ancestors first tamed and bred gray wolves 30 to 40 thousand years as a means of providing their children with a companion to keep them occupied and feeling less alone as they dealt with the emotional trauma of their mother and father splitting up. The funnies part of this article is in its arguments about taming wild animals. Nowadays, we can rarely see a tamed wolf, all because they are wild and dangerous. I can`t possibly imagine a wolf instead of a cat for example, as a friend for children. In my opinion, The Onion`s article is parodying a story about Mowgli from “The Jungle Book” series, where a boy whose name is Mowgli was found as a baby and raised by the wolves. 3. I chose this story because I found it unrealistic and funny. It also reminded me about a story of Mowgli that I read in my childhood. 4. I know that people always tried to tame different animals, including wild ones. Taming a wild horse is difficult; taming a wild elephant is even more difficult. However it`s almost impossible to tame a wild hunter, like wolf or lion, unless you do it since their first days of life...

AGRICULTURE TAKES A BIG BITE: THE ECOLOGICAL FOOTPRINT OF THE GLOBAL FOOD SYSTEM After air and water, food is the most essential resource people require to sustain themselves. These resources are provided by the layer of interconnected life that covers our planet: the biosphere. Yet the way the food system provides food often severely damages the health of the biosphere through soil and aquifer depletion, deforestation, aggressive use of agrochemicals, fishery collapses, and the loss of biodiversity in crops, livestock, and wild species. The global food system has become such a dominant force shaping the surface of this planet and its ecosystems that we can no longer achieve sustainability without revamping the food system. At the same time sustainable food systems provide great hope for building a sustainable future—a future in which all can lead satisfying lives within the means of the biosphere. In this brief, we use Ecological Footprint analysis to document the current food system’s demand on the biosphere. Ecological Footprint accounts track the area of biologically productive land and water needed to produce the resources consumed by a given population and to absorb its waste. The Ecological Footprint...
