Power (International Relations)
Power in international relations is defined in several different ways. Modern discourse generally speaks in terms of state power, indicating both economic and military power. Those states that have significant amounts of power within the international system are referred to as small powers, middle powers, regional powers, great powers, superpowers, or hegemons, although there is no commonly accepted standard for what defines a powerful state. NATO Quint, the G7, the BRICS nations and the G20 are seen by academics as forms of governments that exercise varying degrees of influence within the international system. Entities other than states can also be relevant in power acquisition in international relations. Such entities can include multilateral international organizations, military alliance organizations like NATO, multinational corporations like Wal-Mart, non-governmental organizations such as the Roman Catholic Church, or other institutions such as the Hanseatic League and technology companies like Facebook and Google.

Saraswati
Saraswati (Sanskrit: सरस्वती, IAST: Sarasvatī) is the Hindu goddess of knowledge, music, art, speech, wisdom, and learning. She is a part of the tridevi of Saraswati, Lakshmi, and Parvati. All the three equal forms unite with the trimurti of Brahma, Vishnu, and Shiva to create, maintain, and regenerate the Universe, respectively. The earliest known mention of Saraswati as a goddess is in the Rigveda. She has remained significant as a goddess from the Vedic period through modern times of Hindu traditions. She is generally shown to have four arms, holding a book, a rosary, a water pot and a musical instrument called Veena. Each of these items have symbolic meaning in Hinduism. Some Hindus celebrate the festival of Vasant Panchami (the fifth day of spring, and also known as Saraswati Puja and Saraswati Jayanti in so many parts of India) in her honour, and mark the day by helping young children learn how to write the letters of the alphabet on that day. The Goddess is also revered by believers of the Jain religion of west and central India, as well as some Buddhist sects.

Information and Communications Technology
Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual, that enable users to access, store, transmit, understand and manipulate information. ICT is also used to refer to the convergence of audiovisuals and telephone networks with computer networks through a single cabling or link system. There are large economic incentives to merge the telephone networks with the computer network system using a single unified system of cabling, signal distribution, and management. ICT is an umbrella term that includes any communication device, encompassing radio, televiision, cell phones, computer and network hardware, satellite systems and so on, as well as the various services and appliances with them such as video conferencing and distance learning. ICT also includes analog technology, such as paper communication, and any mode that transmits communication. ICT is a broad subject and the concepts are evolving. It covers any product that will store, retrieve, manipulate, transmit, or receive information electronically in a digital form (e.g., personal computers including smartphones, digital television, email, or robots). Skills Framework for the Information Age is one of many models for describing and managing competencies for ICT professionals for the 21st century.

Huītzilōpōchtli
In Aztec mythology, Huitzilopochtli (Template:Lang-nci-IPA, modern Nahuatl pronunciation (help·info)) is the deity of war, sun, human sacrifice, and the patron of the city of Tenochtitlan. He was also the tribal god of the Mexicas, also known as the Aztecs, of Tenochtitlan. Many in the pantheon of deities of the Aztecs were inclined to have a fondness for a particular aspect of warfare. However, Huitzilopochtli was known as the primary god of war in ancient Mexico. Since he was the patron god of the Mexica, he was credited with both the victories and defeats that the Mexica people had on the battlefield. The people had to make sacrifices to him to protect the Aztec from infinite night. He wielded Xiuhcoatl, the fire serpent, as a weapon, thus also associating Huitzilopochtli with fire. As noted by the Spaniards during their discovery and conquest of the Aztec Empire (wherein they recorded the deity's name as Huichilobos), human sacrifice was common in worship ceremonies, which took place frequently and in numerous temples throughout the region, and when performed they typically sacrificed multiple victims per day at a given temple.

Hot Dry Rock Geothermal Energy
Hot dry rock (HDR) is an extremely abundant source of geothermal energy that is difficult to access. A vast store of thermal energy is contained within hot – but essentially dry and impervious crystalline basement rocks found almost everywhere deep beneath Earth's surface. A concept for the extraction of useful amounts of geothermal energy from HDR originated at the Los Alamos National Laboratory in 1970, and Laboratory researchers were awarded a U.S. patent covering it. This technology has been tested extensively with multiple deep wells drilled in several field areas around world including the USA, Japan, Australia, France, and the UK and investment of billions of research funds. It continues to be the focus along with a related technique called EGS for sizable government-led research studies involving costly deep drilling and rock studies. Thermal energy has been recovered in reasonably sustainable tests over periods of years and in some cases electrical power generation was also achieved. However no commercial projects are ongoing or likely due to the high cost and limited capacity of the engineered reservoirs, associated wells, and pumping systems. Commonly tests have opened just one or more fractures such that the reservoir surface heat exchange areas are limited. For this technology to successfully compete with other energy sources, drilling costs would have to drop drastically or new approaches that result in much more extensive, complex, and higher rate flow paths through actual fracture networks would have to be established. The enthusiasim evident here on Wikipedia and in the research community is justified by the vast extent of the energy supply and the low environmental impact of the method however significant breakthroughs will be required to make this a commercial energy resource.

Bicameralism (Psychology)
Bicameralism[Note 1] (the condition of being divided into "two-chambers") is a controversial hypothesis in psychology and neuroscience which argues that the human mind once operated in a state in which cognitive functions were divided between one part of the brain which appears to be "speaking", and a second part which listens and obeys—a bicameral mind, and that the evolutionary breakdown of this division gave rise to consciousness in humans. The term was coined by Julian Jaynes, who presented the idea in his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind, wherein he made the case that a bicameral mentality was the normal and ubiquitous state of the human mind as recently as 3,000 years ago, near the end of the Mediterranean bronze age.

Light cured dental composite resins
The photoinduced polymerization of monomers is currently an essential tool in various industries. The photopolymerization process plays an increasingly important role in biomedical applications. It is especially used in the production of dental composites. It also exhibits unique properties, such as a short time of polymerization of composites (up to a few seconds), low e tes with their limitations and disadvantages. nergy consumption, and spatial resolution (polymerization only in irradiated areas). This entry describes a short overview of the history and classification of different typical monomers and photoinitiating systems such as bimolecular photoinitiator system containing camphorquinone and aromatic amine, 1-phenyl-1,2-propanedione, phosphine derivatives, germanium derivatives, hexaarylbiimidazole derivatives, silane-based derivatives and thioxanthone derivatives used in the production of dental composites with their limitations and disadvantages.
