East Orange is a city in Essex County, New Jersey, United States. As of the 2010 United States Census the city's population was 64,270, reflecting a decline of 5,554 (−8.0%) from the 69,824 counted in the 2000 Census, which had in turn declined by 3,728 (−5.1%) from the 73,552 counted in the 1990 Census.

The Census Bureau's Population Estimates Program calculated that the city's population was 64,367 in 2019, ranking the city the 590th-most-populous in the country.
The City of Orange is a township in Essex County, New Jersey, United States.

Jaffa Cakes are biscuit-sized cakes introduced by McVitie and Price in the UK in 1927 and named after Jaffa oranges. The most common form of Jaffa cakes are circular, 2+1⁄8 inches (54 mm) in diameter and have three layers: a Genoise sponge base, a layer of orange flavoured jam and a coating of chocolate. Each cake is 46 calories. Jaffa cakes are also available as bars or in small packs, and in larger and smaller sizes. The original Jaffa Cakes now come in packs of 10, 20, 30, or 40, having been downsized in 2017 from 12 or 24 per pack.
Stereolithography is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and oligomers to cross-link together to form polymers. Those polymers then make up the body of a three-dimensional solid. Research in the area had been conducted during the 1970s, but the term was coined by Chuck Hull in 1984 when he applied for a patent on the process, which was granted in 1987. Stereolithography can be used to create prototypes for products in development, medical models, and computer hardware, as well as in many other applications. While stereolithography is fast and can produce almost any design, it can be expensive.
The Orange Line is the longest and first-planned of the four subway lines of the Montreal Metro in Montreal, Quebec, Canada. It formed part of the initial network, and was extended from 1980 to 1986.

In modern English, the nouns vates and ovate (, ), are used as technical terms for ancient Celtic bards, prophets and philosophers. The terms correspond to a Proto-Celtic word which can be reconstructed as *wātis. They are sometimes also used as English equivalents to later Celtic terms such as Irish fáith "prophet, seer".
Taxation in the Republic of Ireland in 2017 came from Personal Income taxes, and Consumption taxes, being VAT and Excise and Customs duties. Corporation taxes represents most of the balance, but Ireland's Corporate Tax System (CT) is a central part of Ireland's economic model. Ireland summarises its taxation policy using the OECD's Hierarchy of Taxes pyramid, which emphasises high corporate tax rates as the most harmful types of taxes where economic growth is the objective. The balance of Ireland's taxes are Property taxes and Capital taxes.
Vat dyes are a class of dyes that are classified as such because of the method by which they are applied. Vat dyeing is a process that refers to dyeing that takes place in a bucket or vat. The original vat dye is indigo, once obtained only from plants but now often produced synthetically.
The class Flavobacteriia is composed of a single order of environmental bacteria. According to Bernardet et al., Flavobacteriia are Gram-negative aerobic rods, 2–5 μm long, 0.3–0.5 μm wide, with rounded or tapered ends that are motile by gliding, yellow colonies on agar, decompose several polysaccharides but not cellulose, G+C contents of 32–37%, and are widely distributed in soil and fresh and seawater habitats. In particular, Flavobacteriia are prominent members of marine biofilms. The type species Flavobacterium aquatile was isolated from a well in Kent, England.
DailyMed is a website operated by the U.S. National Library of Medicine (NLM) to publish up-to-date and accurate drug labels to health care providers and the general public. The contents of DailyMed is provided and updated daily by the U.S. Food and Drug Administration (FDA). The FDA in turn collects this information from the pharmaceutical industry.
1110 Jaroslawa is a bright background asteroid and rather slow rotator from the inner regions of the asteroid belt. The stony S-type asteroid has a rotation period of 97.4 hours and measures approximately 13 kilometers in diameter. It was discovered at the Simeiz Observatory on the Crimean peninsula on 10 August 1928, by astronomer Soviet Grigory Neujmin, who named it after his son, Jaroslav Grigorevich Neujmin.
The European Union value-added tax is a value added tax on goods and services within the European Union (EU). The EU's institutions do not collect the tax, but EU member states are each required to adopt a value added tax that complies with the EU VAT code. Different rates of VAT apply in different EU member states, ranging from 17% in Luxembourg to 27% in Hungary. The total VAT collected by member states is used as part of the calculation to determine what each state contributes to the EU's budget.
Vat Phou is a ruined Khmer Hindu temple complex in southern Laos. It is at the base of mount Phou Khao, some 6 kilometres (3.7 mi) from the Mekong in Champasak Province. There was a temple on the site as early as the 5th century, but the surviving structures date from the 11th to 13th centuries. It has a unique structure: The elements lead to a shrine where a lingam dedicated to Lord Shiva was bathed in water from a mountain spring. The site later became a centre of Theravada Buddhist Warrior's worship, birth grounds for warrior offsprings, which it remains today.

63 Ceti is a star in the constellation of Cetus, located just over a degree south of the celestial equator. With an apparent magnitude of about 5.9, the star is barely visible to the naked eye as a dim, orange-hued point of light. Parallax estimates put it at a distance of about 390 light years away from the Earth, and it is drifting further away with a radial velocity of 28 km/s.
Dibromoanthanthrone is a scarlet or orange-red-hue synthetic organic colourant.
A value-added tax (VAT), known in some countries as a goods and services tax (GST), is a type of tax that is assessed incrementally. It is levied on the price of a product or service at each stage of production, distribution, or sale to the end consumer. If the ultimate consumer is a business that collects and pays to the government VAT on its products or services, it can reclaim the tax paid. It is similar to, and is often compared with, a sales tax.
HD 142250 is a star in the constellation Scorpius. It has a visual apparent magnitude of 6.10, being visible to the naked eye only in excellent seeing conditions. From parallax measurements, it is located about 500 light-years (155 parsecs) away from Earth. This distance, together with the star's proper motion, indicate that HIP 77900 is a member of the Upper Scorpius subgroup of the Scorpius–Centaurus Association, the nearest OB association to the Sun. This subgroup is the youngest of the three of the association, with an estimated age of 11 million years.
