Anti-Graffiti Treatments on Natural Stone Materials
Graffiti vandalism represents an aesthetic and structural phenomenon of degradation both for buildings and cultural heritage: the most used sprays and markers can permeate the stone materials exposing them to degradation. Hence, great attention is being currently devoted to new non-invasive chemical approaches to face this urgent problem. This work is aimed at deeply examining the effects of some of the most sustainable chemical protective methods on the physical properties of natural building materials (e.g., tuff and limestone) by testing two commercial antigraffiti products.

Anthroposophic Medicine
Anthroposophic medicine (or anthroposophical medicine) is a form of alternative medicine based on pseudoscientific and occult notions. Devised in the 1920s by Rudolf Steiner (1861–1925) in conjunction with Ita Wegman (1876–1943), anthroposophical medicine draws on Steiner's spiritual philosophy, which he called anthroposophy. Practitioners employ a variety of treatment techniques based upon anthroposophic precepts, including massage, exercise, counselling, and substances. Many drug preparations used in anthroposophic medicine are ultra-diluted substances, similar to those used in homeopathy. Homeopathic remedies are not medically effective and are generally considered harmless, except when used as a substitute for a scientifically proven and effective cure. In certain European countries, people with cancer are sometimes prescribed remedies made from specially harvested mistletoe, although no evidence of clinical benefit exists. Some anthroposophic doctors oppose childhood vaccination, and this has led to preventable outbreaks of disease. Anthroposophic medicine departs from fundamental biological principles in several respects. For example, Steiner said that the heart is not a pump, but that the blood in a sense pumps itself. Anthroposophic medicine also proposes that patients' past lives may influence their illness and that the course of an illness is subject to karmic destiny. Professor of complementary medicine Edzard Ernst and other physicians and scientists including Simon Singh and David Gorski have characterized anthroposophic medicine as pseudoscientific quackery, with no basis in reason or logic.

Ante-Nicene Period
The Ante-Nicene Period (literally meaning "before Nicaea") of the history of early Christianity was the period following the Apostolic Age of the 1st century down to the First Council of Nicaea in 325. This period of Christian history had a significant impact on the unity of doctrine across all Christendom and the spreading of Christianity to a greater area of the world. Those seen as prominent figures of this era, referred to as the Ante-Nicene Fathers or Proto-orthodox Christians, generally agreed on most doctrine while the teachings of those early Christian writers which the general majority considered to be heretical, were rejected.

Anno Mundi
Anno Mundi (Latin for "in the year of the world"; Hebrew: לבריאת העולם, "to the creation of the world"), abbreviated as AM, or Year After Creation, is a calendar era based on the biblical accounts of the creation of the world and subsequent history. Two such calendar eras have seen notable use historically: While differences in biblical interpretation or in calculation methodology can produce some differences in the creation date, most results fall relatively close to one of these two dominant models. The primary reason for the disparity seems to lie in which underlying Biblical text is chosen (roughly 5500 BC based on the Greek Septuagint text, about 3750 BC based on the Hebrew Masoretic text). Most of the 1,732-year difference resides in numerical discrepancies in the genealogies of the two versions of the Book of Genesis. Patriarchs from Adam to Terah, the father of Abraham, are said to be older by as much as 100 years or more when they begat their named son in the Greek Septuagint than they were in the Latin Vulgate (Genesis 5; Genesis 11) or the Hebrew Tanakh (Gen 5; Gen 11). The net difference between the two major genealogies of Genesis is 1466 years (ignoring the "second year after the flood" ambiguity), 85% of the total difference. (See Dating creation.)

Anglophone Problem (Cameroon)
The Anglophone Problem, as it is commonly referred to in Cameroon, is a socio-political issue rooted in Cameroon's colonial legacies from the Germans, British, and the French. The issue classically and principally opposes many Cameroonians from the Northwest and Southwest regions, many of whom consider themselves anglophones, to the Cameroon government. This is based on the fact that these two regions (formally British Southern Cameroons) were controlled by Britain as a mandated and trust territory of the League of Nations and the United Nations respectively."

Andalusian Arabic
Andalusian Arabic, also known as Andalusi Arabic, was a variety or varieties of Arabic spoken in Al-Andalus, the regions of the Iberian Peninsula (modern Spain and Portugal) under Muslim rule (and for some time after) from the 9th century to the 17th century. It became an extinct language in Iberia after the expulsion of the former Hispanic Muslims, which took place over a century after the Granada War by the Catholic Monarchs of Spain. Once widely spoken in Iberia, the expulsions and persecutions of Arabic speakers caused an abrupt end to the language's use on the peninsula. Its use continued to some degree in North Africa after the expulsion, although Andalusi speakers were rapidly assimilated by the Maghrebi communities to which they fled.

Ancient Urban Land-Use Based on Geographic Information System
As ancient cities are spaces that represent the development of civilization, it is worth exploring and studying their characteristics and conceptions of land use. The city plan was calibrated with the help of satellite remote sensing images and sites. By constructing the “urban element area acquisition and analysis model”, various operations for areas in the city plan were realized, including an area value calculation, land use structure calculation, area modulus analysis, area ratio analysis between areas, and determination of the cultural significance of numbers and ratios. Taking the Sui and Tang dynasties capital city of Chang'an as an example, it will be described in detail below.
