Jaffa Cakes British snack food

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+18 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 3D printing technique

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.

Taxation in the Republic of Ireland Irish tax code

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.

Flavobacteriia Class of bacteria

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.

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.

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.

Value-added tax Form of consumption tax

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.
