Preterism
Preterism, a Christian eschatological view, interprets some (partial preterism) or all (full preterism) prophecies of the Bible as events which have already happened. This school of thought interprets the Book of Daniel as referring to events that happened from the 7th century BC until the first century AD, while seeing the prophecies of the Book of Revelation as events that happened in the first century AD. Preterism holds that Ancient Israel finds its continuation or fulfillment in the Christian church at the destruction of Jerusalem in AD 70. The term preterism comes from the Latin praeter, which is a prefix denoting that something is "past" or "beyond". Adherents of preterism are known as preterists. Preterism teaches that either all (full preterism) or a majority (partial preterism) of the Olivet discourse had come to pass by AD 70. Historically, preterists and non-preterists have generally agreed that the Jesuit Luis de Alcasar (1554–1613) wrote the first systematic preterist exposition of prophecy Vestigatio arcani sensus in Apocalypsi (published in 1614) during the Counter-Reformation.

Olfaction and Ligand–Receptor Interaction
Odorant or olfactory receptors (ORs) are located in the human nose, in the olfactory epithelium. The olfactory receptors can recognize many different odor molecules of a diverse protein sequence, and OR genes constitute the most abundant family of G protein-coupled receptors (GPCRs). The human receptor gene family comprises 339 receptor genes and 297 receptor pseudogenes, unequally dispersed in 51 distinct loci on 21 human chromosomes. Humans have a compassionate sense of smell, which is essential for discovering odors necessary for maintaining a healthy life, such as the smell of smoke (detection of fire) and rotten food (to avoid ingestion).

Porcelain Enamel Coatings
Porcelain enamel is an inorganic-type coating, which is applied to metals or glass for both decorative and functional purposes. This coating is a silica-based solidified glass mass obtained by high-temperature firing (temperature can range between 450 and 1200 °C depending on the substrate). Porcelain enamel coatings differ from ceramic coatings mainly by their glass structure and dilatation coefficient, and from organic paints mainly by the inorganic nature of the matrix and the chemical bond that exists between the coating and the substrate.

Holobiont
A holobiont is an assemblage of a host and the many other species living in or around it, which together form a discrete ecological unit, though there is controversy over this discreteness. The components of a holobiont are individual species or bionts, while the combined genome of all bionts is the hologenome. The concept of the holobiont was initially defined by Dr. Lynn Margulis in her 1991 book Symbiosis as a Source of Evolutionary Innovation, though the concept has subsequently evolved since the original definition. Holobionts include the host, virome, microbiome, and other members, all of which contribute in some way to the function of the whole. Well-studied holobionts include reef-building corals and humans.

Insights into Si-Si and Si-H Bond
During the last decades, the search for new methodologies for the synthesis of organosilicon compounds have increased due to the multiple applications in industry, in academy, among other areas. Silicon-hydrogen and silicon-silicon bond activation by d-block metals still represent the most important pathways for obtaining molecular entities that contain, witihin their structures, silane motifs. Although the chemistry of Si-H bond activation is under continue development, Si-Si bonds are poorly characterized and less used and thus, disilanes represent good starting precursors because of their stability towards ambient conditions. The present entry will focus on the physicochemical properties of Si-H and Si-Si bonds, some trends and finally highlighting their impact on the synthesis of metal complexes.

Tandem Mass Spectrometry
Tandem mass spectrometry, also known as MS/MS or MS2, involves multiple steps of mass spectrometry selection, with some form of fragmentation occurring in between the stages. In a tandem mass spectrometer, ions are formed in the ion source and separated by mass-to-charge ratio in the first stage of mass spectrometry (MS1). Ions of a particular mass-to-charge ratio (precursor ions) are selected and fragment ions (product ions) are created by collision-induced dissociation, ion-molecule reaction, photodissociation, or other process. The resulting ions are then separated and detected in a second stage of mass spectrometry (MS2).

Psychological Effects of Method Acting
Method acting is employed by actors to evoke realistic emotions into their performance by drawing on personal experiences. Raymond Hamden, doctor of Clinical and Forensic Psychology, defines the purpose of method acting as “compartmentalizing their own feelings while playing another character [so] they could bring the emotions of that personal feeling to cry if they needed to with that character.” However, when these emotions are not compartmentalized, they can encroach on other facets of life, often seeming to disrupt the actor’s psyche. This occurs as the actor delves into previous emotional experiences, be they joyful or traumatic. The psychological effects, like emotional fatigue, comes when suppressed or unresolved raw emotions are unburied to add to the character, not just from the employing personal emotions in performance. The question becomes whether the actor calls up resolved or unresolved emotions in their acting.

Quadruple and Quintuple Innovation Helix (Q2IH) Framework
The quadruple along with the quintuple innovation helix framework was co-developed by Elias G. Carayannis and David F.J. Campbell, with the quadruple helix being described in a 2009 article and the quintuple helix in a 2010 article. It extends and expands substantially the triple helix model of innovation economics as the framework introduces civil society and the environment as pillars and focal points of policy and practice. In particular, civil society emphasizes the role of bottom-up initiatives complementing top-down government, university and industry policies and practices, and the environment emphasizes the sustainability priorities and exigencies that need to inform and moderate top-down policies and practices as well as bottom-up initiatives. Within the quintuple helix, these represent the sine qua non of smart, sustainable and inclusive growth. The quintuple helix views the natural environments of society and the economy as drivers for knowledge production and innovation, thus defining opportunities for the knowledge society and knowledge economy. The quintuple helix can be described in terms of the models of knowledge that it extends, the five subsystems (helices) it incorporates, and the steps involved in the circulation of knowledge. How to define these new helices has been debated and some researchers see them as additional helices while some see them as different types of helix which overarch the previous helices.

Rural Planning
Rural planning is a broad academic term and human practice covering a range of topics, such as rural landscape, industry development, livelihoods of villagers and farmers, environmental conservation, and health care delivery. The objective of rural planning is to achieve rural development through the allocation and management of resources, mediated by developmentalist configuration and local communities. Rural planning could be organized at different levels, from global, national, and regional plans to plans at a village level. The time span of a rural planning is also very diverse, ranging from years to decades.

Paleoconservatism
Paleoconservatism (sometimes shortened to paleocon) is a conservative political philosophy stressing tradition, limited Federal government and civil society, along with religious, regional, national and Western identity.[lower-alpha 1] According to the international relations scholar Michael Foley, "paleoconservatives press for restrictions on immigration, a rollback of multicultural programmes, the decentralization of federal policy, the restoration of controls upon free trade, a greater emphasis upon economic nationalism and non-interventionism in the conduct of American foreign policy, and a generally revanchist outlook upon a social order in need of recovering old lines of distinction and in particular the assignment of roles in accordance with traditional categories of gender, ethnicity, and race". Practitioners of this philosophy identify themselves as the legitimate heirs to the American conservative tradition. The nativist politician Pat Buchanan was strongly influenced by the Rockford Institute's Chronicles and helped create another paleoconservative publication, The American Conservative. Paleoconservativism's concerns overlap those of the Old Right that opposed the New Deal in the 1930s and 1940s as well as American social conservatism of the late 20th century expressed, for example, in the book Single Issues by Joseph Sobran. The political theorist Paul Gottfried is credited with coining the term in the 1980s. He says the term originally referred to various Americans, such as conservative and traditionalist Catholics and agrarian Southerners, who turned to anti-communism during the Cold War.

Quaternary Numeral System
A quaternary /kwəˈtɜːrnəri/ numeral system is base-4. It uses the digits 0, 1, 2 and 3 to represent any real number. Four is the largest number within the subitizing range and one of two numbers that is both a square and a highly composite number (the other being 36), making quaternary a convenient choice for a base at this scale. Despite being twice as large, its radix economy is equal to that of binary. However, it fares no better in the localization of prime numbers (the smallest better base being the primorial base six, senary). Quaternary shares with all fixed-radix numeral systems many properties, such as the ability to represent any real number with a canonical representation (almost unique) and the characteristics of the representations of rational numbers and irrational numbers. See decimal and binary for a discussion of these properties.

Applications of Cyclodextrins
Due to their unique structural, physical and chemical properties, cyclodextrins and their derivatives have been of great interest to scientists and researchers in both academia and industry for over a century. Many of the industrial applications of cyclodextrins have arisen from their ability to encapsulate, either partially or fully, other molecules, especially organic compounds. Cyclodextrins are non-toxic oligopolymers of glucose that help to increase the solubility of organic compounds with poor aqueous solubility, can mask odors from foul-smelling compounds, and have been widely studied in the area of drug delivery.

Paternoster
A paternoster (/ˈpeɪtərˈnɒstər/, /ˈpɑː-/, or /ˈpæ-/) or paternoster lift is a passenger elevator which consists of a chain of open compartments (each usually designed for two persons) that move slowly in a loop up and down inside a building without stopping. Passengers can step on or off at any floor they like. The same technique is also used for filing cabinets to store large amounts of (paper) documents or for small spare parts. The much smaller belt manlift which consists of an endless belt with steps and rungs but no compartments is also sometimes called a paternoster. The name paternoster ("Our Father", the first two words of the Lord's Prayer in Latin) was originally applied to the device because the elevator is in the form of a loop and is thus similar to rosary beads used as an aid in reciting prayers. The construction of new paternosters was stopped in the mid-1970s due to safety concerns, but public sentiment has kept many of the remaining examples open. By far most remaining paternosters are in Europe, with 230 examples in Germany, and 68 in the Czech Republic. Only three have been identified outside Europe: one in Malaysia, one in Sri Lanka, and another in Peru.

Anatta
In Buddhism, the term anattā (Pali) or anātman (Sanskrit) refers to the doctrine of "non-self", that there is no unchanging, permanent self, soul or essence in phenomena. It is one of the seven beneficial perceptions in Buddhism, and one of the three marks of existence along with dukkha (suffering) and anicca (impermanence). The Buddhist concept of anatta or anatman is one of the fundamental differences between Buddhism and Hinduism, with the latter asserting that atman (self, soul) exists.

Business Environment and Competitive Advantages
       Tourism destination competitiveness reflecting the generic characteristics should be considered diversified to notice the distinctive perspective between the business environment and competitive advantages. Criticism of some prior conventional literature stems from the lack of a rigorous process to find the structure and attributes of the measurement items for a destination’s business environment and competitive advantages. The available theoretical framework and measures containing the destination business environment and competitive advantages warrant further investigation. The vital dimensions of the destination business environment (i.e., dynamism,hostility,turbulence,investment,information technology,and governance) and destination competitive advantages (i.e., defensiveness, local acceptance, accessibility, reasonability, uniqueness, supportiveness, and image sustainability) were successfully identified through quantitative and empirical analysis, which could provide a significant basis for managerial and policy decisions in the tourism industry.

Declaration of War
A declaration of war is a formal act by which one state goes to war against another. The declaration is a performative speech act (or the signing of a document) by an authorized party of a national government, in order to create a state of war between two or more states. The legality of who is competent to declare war varies between nations and forms of government. In many nations, that power is given to the head of state or sovereign. In other cases, something short of a full declaration of war, such as a letter of marque or a covert operation, may authorise war-like acts by privateers or mercenaries. The official international protocol for declaring war was defined in the Hague Convention (III) of 1907 on the Opening of Hostilities. Since 1945, developments in international law such as the United Nations Charter, which prohibits both the threat and the use of force in international conflicts, have made declarations of war largely obsolete in international relations. The UN Security Council, under powers granted in articles 24 and 25, and Chapter VII of the Charter, may authorize collective action to maintain or enforce international peace and security. Article 51 of the United Nations (UN) Charter also states that: "Nothing in the present Charter shall impair the inherent right to individual or collective self-defence if an armed attack occurs against a state." Few nations have formally declared war upon another since then. In addition to this, non-state or terrorist organizations may claim to or be described as "declaring war" when engaging in violent acts. These declarations may have no legal standing in themselves, but they may still act as a call to arms for supporters of these organizations.
