Methods for Recycling Heterogenous Catalysts
The rapid separation and efficient recycling of catalysts after a catalytic reaction are considered important requirements along with the high catalytic performances. In this view, although heterogeneous catalysis is generally less efficient if compared to the homogeneous type, it is generally preferred since it benefits from the easy recovery of the catalyst. Recycling of heterogeneous catalysts using traditional methods of separation such as extraction, filtration, vacuum distillation, or centrifugation is tedious and time-consuming. They are uneconomic processes and, hence, they cannot be carried out in the industrial scale.

Dynamic-Maturational Model of Attachment and Adaptation
The dynamic-maturational model of attachment and adaptation (DMM) is a transdisciplinary model describing the effect attachment relationships can have on human development and functioning. It is especially focused on the effects of relationships between children and parents and between romantic/reproductive couples. It developed initially from attachment theory as developed by John Bowlby and Mary Ainsworth, and incorporated many other theories into a comprehensive model of adaptation to life's many dangers. The DMM was initially created by developmental psychologist Patricia McKinsey Crittenden and her colleagues including David DiLalla, Angelika Claussen, Andrea Landini, Steve Farnfield, and Susan Spieker. A main tenant of the DMM is that exposure to danger drives neural development and adaptation to promote survival. Danger includes relationship danger. In DMM-attachment theory, when a person needs protection or comfort from danger from a person with whom they have a protective relationship, the nature of the relationship generates relation-specific self-protective strategies. These are patterns of behavior which include the underlying neural processing. The DMM protective strategies describe aspects of the parent-child relationship, romantic relationships, and to a degree, relationships between patients/clients and long-term helping professionals.

Division of Labour
The division of labour is the separation of tasks in any economic system or organisation so that participants may specialise (specialisation). Individuals, organizations, and nations are endowed with or acquire specialised capabilities and either form combinations or trade to take advantage of the capabilities of others in addition to their own. Specialised capabilities may include equipment or natural resources as well as skills and training and combinations of such assets acting together are often important. For example, an individual may specialise by acquiring tools and the skills to use them effectively just as an organization may specialize by acquiring specialised equipment and hiring or training skilled operators. The division of labour is the motive for trade and the source of economic interdependence. Historically, an increasing division of labour is associated with the growth of total output and trade, the rise of capitalism, and the increasing complexity of industrialised processes. The concept and implementation of division of labour has been observed in ancient Sumerian (Mesopotamian) culture, where assignment of jobs in some cities coincided with an increase in trade and economic interdependence. Division of labour generally also increases both producer and individual worker productivity. After the Neolithic Revolution, pastoralism and agriculture led to more reliable and abundant food supplies, which increased the population and led to specialisation of labour, including new classes of artisans, warriors, and the development of elites. This specialistion was furthered by the process of industrialisation, and Industrial Revolution-era factories. Accordingly, many classical economists as well as some mechanical engineers such as Charles Babbage were proponents of division of labour. Also, having workers perform single or limited tasks eliminated the long training period required to train craftsmen, who were replaced with lesser paid but more productive unskilled workers.

Classification of the Approved EGFR-TKIs
Targeting EGFR with small-molecule inhibitors is a valid strategy in cancer therapy. Since the approval of the first EGFR-TKI in 2003, a huge number of EGFR inhibitors were reported. Classification of these inhibitors could help the researchers to understand their structure-activity relationship. Herein, we introduce different types of classifications of the EGFR-TKIs, which received global approval for clinical use. In the following, the EGFR-targeting drugs are classified based on their chemistry, clinical use, target kinases, and the type of inhibition/interaction with EGFR.

Deep Sea Fish
Deep-sea fish are animals that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout. Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor. Deep-sea organisms generally inhabit bathypelagic (1000–4000m deep) and abyssopelagic (4000–6000m deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200–1000m deep) zone as well. The mesopelagic zone is the disphotic zone, meaning light there is minimal but still measurable. The oxygen minimum layer exists somewhere between a depth of 700m and 1000m deep depending on the place in the ocean. This area is also where nutrients are most abundant. The bathypelagic and abyssopelagic zones are aphotic, meaning that no light penetrates this area of the ocean. These zones make up about 75% of the inhabitable ocean space. The epipelagic zone (0–200m) is the area where light penetrates the water and photosynthesis occurs. This is also known as the photic zone. Because this typically extends only a few hundred meters below the water, the deep sea, about 90% of the ocean volume, is in darkness. The deep sea is also an extremely hostile environment, with temperatures that rarely exceed 3 °C (37.4 °F) and fall as low as −1.8 °C (28.76 °F) (with the exception of hydrothermal vent ecosystems that can exceed 350 °C, or 662 °F), low oxygen levels, and pressures between 20 and 1,000 atmospheres (between 2 and 100 megapascals).

Rock Art
The term ‘rock art’ defines non-utilitarian humanly made markings on natural rock surfaces, caused either by an additive (pictograms, made by the application of material) or a reductive process (petroglyphs, made by the removal of rock material). The former include rock paintings, pigment drawings, stencils, and beeswax figures; the latter term covers engravings, percussion petroglyphs, and finger flutings. Rock art occurs in nearly all countries. Its uneven distribution is attributable to differences in cultural conventions as well as a taphonomic attribute, i.e. a result of preservation bias. Prehistoric rock art represents by far the largest body of evidence we possess of humanity’s cultural, cognitive, and artistic beginnings. Through its relative permanence, it has profoundly influenced the beliefs and cultural conventions of subsequent societies up to the present. It is, therefore, an integral part of humanity's collective memory and the most significant surviving witness of our cultural evolution.

Diarchy
A diarchy (from Greek δι-, di-, "double", and -αρχία, -arkhía, "ruled")[note 1] or duumvirate (from Latin duumvirātus, "the office of the two men")[note 2] is a form of government characterized by corule, with two people ruling a polity together either lawfully or de facto, by collusion and force. The leaders of such a system are usually known as corulers. Historically, diarchy particularly referred to the system of shared rule in British India established by the Government of India Acts 1919 and 1935, which devolved some powers to local councils, which had included native Indian representation under the Indian Councils Act 1892. 'Duumvirate' principally referred to the offices of the various duumviri established by the Roman Republic. Both, along with less common synonyms such as biarchy and tandemocracy,[note 3] are now used more generally to refer to any system of joint rule or office. A monarchy temporarily controlled by two or more people is, however, usually distinguished as a coregency. Corule is one of the oldest forms of government. Historical examples include the Pandyan dynasty of Tamilakam, Sparta's joint kingdom, the Roman Republic's consuls, Carthage's Judges, and several ancient Polynesian societies. Systems of inheritance that often led to corule in Germanic and Dacian monarchies may be included as well, as may the dual occupants of the ranks of the Inca Empire. Modern examples of diarchies are Andorra, whose princes are the President of France and the Bishop of Urgell in Catalonia; and San Marino, whose republic is led by two Captains Regent.

Italic Languages
The Italic languages are a subfamily of the Indo-European language family, originally spoken by Italic peoples. They include Latin and its descendants (the Romance languages) as well as a number of extinct languages of the Italian Peninsula, including Umbrian, Oscan, Faliscan, South Picene, and possibly Venetic and Sicel. With over 800 million native speakers, the Italic languages are the second most widely spoken branch of the Indo-European family, after the Indo-Iranian languages. In the past, various definitions of "Italic" have prevailed. This article uses the classification presented by the Linguist List: Italic includes the Latin subgroup (Latin and the Romance languages) as well as the ancient Italic languages (Faliscan, Osco-Umbrian and two unclassified Italic languages, Aequian and Vestinian). Venetic (the language of the ancient Veneti), as revealed by its inscriptions, shared some similarities with the Italic languages and is sometimes classified as Italic. However, since it also shares similarities with other Western Indo-European branches (particularly Celtic languages), some linguists prefer to consider it as an independent Indo-European language. In the extreme view, Italic did not exist, but the different groups descended directly from Indo-European and converged because of geographic contiguity. That view stems in part from the difficulty in identifying a common Italic homeland in prehistory. In the intermediate view, the Italic languages are one of the ten or eleven major subgroups of the Indo-European language family and might therefore have had an ancestor, Common Italic or Proto-Italic from which its daughter languages descended. Moreover, there are similarities between major groups, but how the similarities are to be interpreted is one of the major debated issues in the historical linguistics of Indo-European. The linguist Calvert Watkins went so far as to suggest, among the ten major groups, a four-way division of East, West, North and South Indo-European. He considered them to be "dialectical divisions within Proto-Indo-European which go back to a period long before the speakers arrived in their historical areas of attestation". It is not to be considered a nodular grouping; in other words, there was not necessarily any common west Indo-European serving as a node from which the subgroups branched but a hypothesised similarity between the dialects of Proto-Indo-European that developed into the recognised families. Although generally regarded as a single branch that diversified from a Common or Proto-Italic stage, after the Proto-Indo-European period, some authors doubt this common affiliation. All the Italic languages share a number of common isoglosses; thus, all of them are centum languages that do not present palatalization of the Indo-European (palatal) velars /*k, *kʷ, *g, *gʰ, *gʰʷ/. The Romance languages present a later palatalization of Latin phonemes /k, g/, although only before phonemes /ɛ, e, i/.

Communalism
Communalism usually refers to a system that integrates communal ownership and federations of highly localized independent communities. A prominent libertarian socialist, Murray Bookchin, defines the Communalism political philosophy that he developed as "a theory of government or a system of government in which independent communes participate in a federation", as well as "the principles and practice of communal ownership". The term 'government' in this case does not imply an acceptance of a State or top-down hierarchy. This usage of communalism appears to have emerged during the late 20th century to distinguish commune-based systems from other political movements and/or governments espousing (if not actually practicing) similar ideas. In particular, earlier communities and movements advocating such practices were often described as "anarchist", "socialist" and/or "communist". Many historical communities practicing utopian socialism or anarcho-communism did implement internal rules of communalist property ownership in the context of federated communalism. It is at least theoretically possible for a federation of communes to include communes which do not practice communalist rules of property, which is to say, that the overall national government may be a federation of communes, but that private property rather than communalist property is the order within each such commune. Karl Marx, often viewed as the founder of modern communism, criticized older forms, including primitive communism and/or utopian socialism, as poorly conceived and/or prone to disintegration in practice. Communalism in the form described above is distinct from the predominant usage in South Asian forms of English: allegiance to a particular ethnic and/or religious group rather than to a broader society. As such, this usage is synonymous with sectarianism and associated with communal violence.

2015–16 Chinese Stock Market Turbulence
The Chinese stock market turbulence began with the popping of the stock market bubble on 12 June 2015 and ended in early February 2016. A third of the value of A-shares on the Shanghai Stock Exchange was lost within one month of the event. Major aftershocks occurred around 27 July and 24 August's "Black Monday". By 8–9 July 2015, the Shanghai stock market had fallen 30 percent over three weeks as 1,400 companies, or more than half listed, filed for a trading halt in an attempt to prevent further losses. Values of Chinese stock markets continued to drop despite efforts by the government to reduce the fall. After three stable weeks the Shanghai index fell again on 24 August by 8.48 percent, marking the largest fall since 2007. At the October 2015 International Monetary Fund (IMF) annual meeting of "finance ministers and central bankers from the Washington-based lender’s 188 member-countries" held in Peru, China's slump dominated discussions with participants asking if "China’s economic downturn [would] trigger a new financial crisis". By the end of December 2015 China's stock market had recovered from the shocks and had outperformed S&P for 2015, though still well below the 12 June highs. By the end of 2015 the Shanghai Composite Index was up 12.6 percent. In January 2016 the Chinese stock market experienced a steep sell-off and trading was halted on 4 and 7 January 2016 after the market fell 7%, the latter within 30 minutes of open. The market meltdown set off a global rout in early 2016. According to 19 January 2016 articles in the Xinhua News Agency, the official press agency of the China , China reported a 6.9 percent GDP growth rate for 2015 and an "economic volume of over ten trillion U.S. dollars". Forbes journalist argues that the "stock market crash does not indicate a blowout of the Chinese physical economy." China is shifting from a focus on manufacturing to service industries and while it has slowed down, it is still growing by 5%. After this last turbulence, as of January 2017 the Shanghai Composite Index has been stable around 3,000 points, 50% less than before the bubble popped.
