List of AMD Athlon Microprocessors
Athlon is the name of a family of CPUs designed by AMD, targeted mostly at the desktop market. It has been largely unused as just "Athlon" since 2001 when AMD started naming its processors Athlon XP, but in 2008 began referring to single core 64-bit processors from the AMD Athlon X2 and AMD Phenom product lines. Later the name began being used for some APUs.

Functional Ecology
Functional ecology is a branch of ecology that focuses on the roles, or functions, that species play in the community or ecosystem in which they occur. In this approach, physiological, anatomical, and life history characteristics of the species are emphasized. The term "function" is used to emphasize certain physiological processes rather than discrete properties, describe an organism's role in a trophic system, or illustrate the effects of natural selective processes on an organism. This sub-discipline of ecology represents the crossroads between ecological patterns and the processes and mechanisms that underlie them. It focuses on traits represented in large number of species and can be measured in two ways – the first being screening, which involves measuring a trait across a number of species, and the second being empiricism, which provides quantitative relationships for the traits measured in screening. Functional ecology often emphasizes an integrative approach, using organism traits and activities to understand community dynamics and ecosystem processes, particularly in response to the rapid global changes occurring in earth's environment. Functional ecology sits at the nexus of several disparate disciplines and serves as the unifying principle between evolutionary ecology, evolutionary biology, genetics and genomics, and traditional ecological studies. It explores such areas as "[species'] competitive abilities, patterns of species co-occurrence, community assembly, and the role of different traits on ecosystem functioning".

Clean Language
Clean Language is a technique primarily used in counseling, psychotherapy and coaching but now also used in education, business, organisational change and health. More recently it has been applied as a research interview technique. Clean Language intends to support clients discovering and developing their own symbols and metaphors, rather than the therapist/coach/interviewer suggesting-contributing their own framing of a topic. In other words, instead of "supporting" the client by offering them ready-made metaphors, when the counselor senses a metaphor would be useful; or, is conspicuous by its absence, the counselor asks the client, "And that's like what?" The client is invited to innovate their own metaphor. The benefit to the counselor is the client is likely to come up with a metaphor from their most-open sensory channel. Learning a client's most open sensory channel is valuable for the counselor for future metaphor construction if the client is stuck. Clean Language was devised by David Grove in the 1980s as a result of his work on clinical methods for resolving clients' traumatic memories. Cei Davies Linn was closely involved in the early evolution and development of Grove's work such as Clean Language and Epistemological Metaphors. As Lawley and Tompkins describe it, Grove realized many clients were describing their symptoms in metaphors drawn from the words of previous therapists, instead of from their own experience. Clean Language also is the basis of Symbolic Modelling, a stand-alone method and process for psychotherapy and coaching, developed by Lawley and Tompkins; Clean Space; and Systemic Modelling, applied in organisational development. Clean Language can also be used in addition to a therapist or coach's existing approach.

The Feynman Lectures on Physics
The Feynman Lectures on Physics is a physics textbook based on some lectures by Richard P. Feynman, a Nobel laureate who has sometimes been called "The Great Explainer". The lectures were presented before undergraduate students at the California Institute of Technology (Caltech), during 1961–1963. The book's co-authors are Feynman, Robert B. Leighton, and Matthew Sands. The Feynman Lectures on Physics is perhaps the most popular physics book ever written. More than 1.5 million English-language copies have been sold; probably even more copies have been sold in a dozen foreign-language editions. A 2013 review in Nature described the book as having "simplicity, beauty, unity ... presented with enthusiasm and insight".

IJkdijk
The IJkdijk is a facility in the Netherlands to test dikes and to develop sensor network technologies for early warning systems. Furthermore, the sensor network will be able to detect many water-related environmental factors that affect the health of humans such as pollution and biological changes. Disasters on rivers and coastal waters are also detected. In studies of dike stability, about eighty dikes will be destroyed and establish, ultimately, a relation between the sensor readings and the future of the dike. Hence the (in Dutch) good-sounding name IJkdijk: dijk=dike and ijk is from the Dutch word ijken=to calibrate (models). Clearly the most urgent goal here is to forecast dike failures. In contrast to popular belief, most disasters with dikes occur because they are too wet and not because they are too low. Another major source of dike failures are streams of water flowing through the dike, ultimately destroying, through erosion, the dike from the inside. A detection system for these failure mechanisms might be cheaper and safer than the alternative: over-dimensioning by adding more clay. As dike improvements are very costly, e.g. 500 euros per meter, there is ample financial room to pay for the sensor system. The IJkdijk will also increase the geophysical understanding of dike behavior. A better understanding of dikes, expressed in a sensor-based early warning system in dikes, prevents unnecessary and costly over-dimensioning. That is good news for the owners of millions of kilometers of dikes that exist nowadays and the developers of millions of kilometers of dikes that will be constructed in the future.

Thrombosis
Thrombosis (from Ancient Greek θρόμβωσις thrómbōsis "clotting") is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss. Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus. Thrombosis may occur in veins (venous thrombosis) or in arteries (arterial thrombosis). Venous thrombosis (sometimes called DVT) leads to a blood clot in the affected part of the body, while arterial thrombosis (and, rarely, severe venous thrombosis) affects the blood supply and leads to damage of the tissue supplied by that artery (ischemia and necrosis). A piece of either an arterial or a venous thrombus can break off as an embolus, which could then travel through the circulation and lodge somewhere else as an embolism. This type of embolism is known as a thromboembolism. Complications can arise when a venous thromboembolism (commonly called a VTE) lodges in the lung as a pulmonary embolism. An arterial embolus may travel further down the affected blood vessel, where it can lodge as an embolism.

Iguvine Tablets
The Iguvine Tablets, also known as the Eugubian Tablets or Eugubine Tables, are a series of seven bronze tablets from ancient Iguvium (modern Gubbio), Italy, written in the ancient Italic language Umbrian. The earliest tablets, written in the native Umbrian alphabet, were probably produced in the 3rd century BC, and the latest, written in the Latin alphabet, from the 1st century BC. The tablets contain religious inscriptions that memorialize the acts and rites of the Atiedian Brethren, a group of 12 priests of Jupiter with important municipal functions at Iguvium. The religious structure present in the tablets resembles that of the early stage of Roman religion, reflecting the Roman archaic triad and the group of gods more strictly related to Jupiter. Discovered in a farmer's field near Scheggia in the year 1444, they are currently housed in the Civic Museum of the Palazzo dei Consoli in Gubbio. The tablets are by far the longest and most important document of any of the Osco-Umbrian group of languages, which are closely related to Latin. The tablets shed light on the grammar of this ancient dead language, and also on the religious practices of the ancient peoples of Italy, including the archaic religion of the Romans. Parts of tablets VI and VII appear to be written in an accentual metre, similar to the Saturnian metre that is encountered in the earliest Latin poetry. The complete text, together with a translation into Latin, was published in London in 1863 by Francis Newman and 1931 in a book by Albrecht von Blumenthal. They were translated into English and published by James W. Poultney in 1959. Although the general meaning of the tablets is clear, there are still many obscure and debated points and issues. The main difficulty in understanding the text is the insufficient knowledge of the Umbrian vocabulary. These are the only documents of full details of sacred rituals from the ancient religions of Europe which have come down to us in an almost complete state. Moreover, their content deals with the rituals (sacrifices and prayers) addressed to the highest gods of the local community and to some extent may reflect the common religious beliefs and practices of the Italic peoples. Consequently, a great number of scholars have devoted their efforts to reading and deciphering them since their discovery. The modern Festival of Ceri, celebrated every year in Gubbio on May 15 in honor of Bishop Ubald or Ubaldo of Gubbio (1084–1160), shares certain features with the rites described in the text and so may be a survival of that ancient pre-Christian custom. It is also celebrated in Jessup, Pennsylvania, a town with a large number of immigrants from the Gubbio area, as Saint Ubaldo Day.
