Auger Electron Spectroscopy
thumb|A Hanford scientist uses an Auger electron spectrometer to determine the elemental composition of surfaces. Auger electron spectroscopy (AES; pronounced [oʒe] in French) is a common analytical technique used specifically in the study of surfaces and, more generally, in the area of materials science. Underlying the spectroscopic technique is the Auger effect, as it has come to be called, which is based on the analysis of energetic electrons emitted from an excited atom after a series of internal relaxation events. The Auger effect was discovered independently by both Lise Meitner and Pierre Auger in the 1920s. Though the discovery was made by Meitner and initially reported in the journal Zeitschrift für Physik in 1922, Auger is credited with the discovery in most of the scientific community. Until the early 1950s Auger transitions were considered nuisance effects by spectroscopists, not containing much relevant material information, but studied so as to explain anomalies in X-ray spectroscopy data. Since 1953 however, AES has become a practical and straightforward characterization technique for probing chemical and compositional surface environments and has found applications in metallurgy, gas-phase chemistry, and throughout the microelectronics industry.

Context-sensitive Solutions (Transport)
Context-sensitive solutions (CSS) is a theoretical and practical approach to transportation decision-making and design that takes into consideration the communities and lands through which streets, roads, and highways pass ("the context"). The term is closely related to but distinguishable from context-sensitive design in that it asserts that all decisions in transportation planning, project development, operations, and maintenance should be responsive to the context in which these activities occur, not simply the design process. CSS seeks to balance the need to move vehicles efficiently and safely with other desirable outcomes, including historic preservation, environmental sustainability, and the creation of vital public spaces. In transit projects, CSS generally refers to context sensitive planning, design, and development around transit stations, also known as transit-oriented development.

Ejabberd
ejabberd is an Extensible Messaging and Presence Protocol (XMPP) application server and an MQ Telemetry Transport (MQTT) broker, written mainly in the Erlang programming language. It can run under several Unix-like operating systems such as macOS, Linux, FreeBSD, NetBSD, OpenBSD and OpenSolaris. Additionally, ejabberd can run under Microsoft Windows. The name ejabberd stands for Erlang Jabber Daemon (Jabber being a former name for XMPP) and is written in lowercase only, as is common for daemon software. ejabberd is free software, distributed under the terms of the GNU GPL-2.0-or-later. (As of 2009), it is one of the most popular open source applications written in Erlang. XMPP: The Definitive Guide (O'Reilly Media, 2009) praised ejabberd for its scalability and clustering feature, at the same time pointing out that being written in Erlang is a potential acceptance issue for users and contributors. The software's creator, Alexey Shchepin was awarded the Erlang User of the Year award at the 2006 Erlang user conference. ejabberd has a number of notable deployments, IETF Groupchat Service, BBC Radio LiveText, Nokia's Ovi, KDE Talk and one in development at Facebook. (As of 2009) ejabberd is the most popular server among smaller XMPP-powered sites that register on xmpp.org. With the next major release after version 2 (previously called ejabberd 3), the versioning scheme was changed to reflect release dates as "Year.Month-Revision" (starting with 13.04-beta1). It was also announced that further development will be split into an "ejabberd Community Server" and an "ejabberd Commercial Edition [which] targets carriers, websites, service providers, large corporations, universities, game companies, that need high level of commitment from ProcessOne, stability and performance and a unique set of features to run their business successfully."

Registrar
{{Multiple issues| Registrar was software used in the personnel or human resources (HR) area of businesses. It was the first piece of software developed to provide HR with the ability to manage training administration, booking people on courses, sending call-up letters, and recording their attendance. It enabled HR users to build their own data dictionaries without any help from their IT people. The Registrar software was created by Silton-Bookman Systems (SBS). It was launched in the US in 1984 and became one of the leading training administration software programs on the market with over 5000 installations. It was eventually incorporated into an LMS when SBS merged with Pathlore in 2000. Therefore, Registrar itself is no longer available for sale. Pathlore was subsequently acquired by SumTotal Systems in 2005.

Red Blood Cells
Red blood cells are the most common type of blood cell and the vertebrate body's principal means of delivering oxygen from the lungs or gills to body tissues via the blood. Red blood cells are also known as RBCs or erythrocytes (from Greek erythros for "red" and kytos for "hollow", with cyte nowadays translated as "cell"). A schistocyte is a red blood cell undergoing fragmentation, or a fragmented part of a red blood cell.

Climate Change Denial: Heads in the Sand
Climate Change Denial: Heads in the Sand is a non-fiction book about climate change denial, coauthored by Haydn Washington and John Cook, with a foreword by Naomi Oreskes. Washington had a background in environmental science prior to authoring the work, and Cook was educated in physics and founded the website Skeptical Science which compiles peer-reviewed evidence of global warming. The book was first published in hardcover and paperback formats in 2011 by Earthscan, a division of Routledge. The book presents an in-depth analysis and refutation of climate change denial, going over several arguments point-by-point and disproving them with peer-reviewed evidence from the scientific consensus for climate change. The authors assert that those denying climate change engage in tactics including cherry picking data purported to support their specific viewpoints, and attacking the integrity of climate scientists. They use social science theory to examine the phenomenon of climate change denial in the wider public, and call this phenomenon a form of pathology. The book traces financial support for climate change denial to the fossil fuel industry, asserting these companies have attempted to influence public opinion on the matter. Washington and Cook write that politicians have a tendency to use weasel words as part of a propaganda tactic through use of spin, as a way to deflect public interest away from climate change and remain passive on the issue. The authors conclude that if the public ceased engaging in denial, the problem of climate change could be realistically addressed. For his research on the book, and efforts in communicating the essence of climate change science to the general public, John Cook won the 2011 Australian Museum Eureka Prize for Advancement of Climate Change Knowledge. Climate Change Denial received a positive reception in reviews from publications including: The Ecologist, ECOS magazine, academic journal Natures Sciences Sociétés, the journal Education published by the New South Wales Teachers Federation,. An article in The New American was critical, describing the labels of "deniers" and "denialists" as cruel and forms of character assassination.

Radial Dysplasia
Radial dysplasia, also known as radial club hand or radial longitudinal deficiency, is a congenital difference occurring in a longitudinal direction resulting in radial deviation of the wrist and shortening of the forearm. It can occur in different ways, from a minor anomaly to complete absence of the radius, radial side of the carpal bones and thumb. Hypoplasia of the distal humerus may be present as well and can lead to stiffness of the elbow. Radial deviation of the wrist is caused by lack of support to the carpus, radial deviation may be reinforced if forearm muscles are functioning poorly or have abnormal insertions. Although radial longitudinal deficiency is often bilateral, the extent of involvement is most often asymmetric. The incidence is between 1:30,000 and 1:100,000 and it is more often a sporadic mutation rather than an inherited condition. In case of an inherited condition, several syndromes are known for an association with radial dysplasia, such as the cardiovascular Holt-Oram syndrome, the gastrointestinal VATER syndrome and the hematologic Fanconi anemia and TAR syndrome. Other possible causes are an injury to the apical ectodermal ridge during upper limb development, intrauterine compression, or maternal drug use (thalidomide).
