Prumnopitys ferruginea

Prumnopitys ferruginea, commonly called miro, is an evergreen coniferous tree which is endemic to New Zealand. Before the genus Prumnopitys was distinguished, it was treated in the related genus Podocarpus as Podocarpus ferrugineus.

It grows up to 25 m high, with a trunk up to 1.3 m diameter. The leaves are linear to sickle-shaped, 15–25 mm long and 2–3 mm broad, with downcurved margins. The plants are dioecious with pollen cones being solitary while those of female plants hang from a curved, scaly stalk. The seed cones are highly modified, reduced to a central stem 2–3 cm long bearing 1-3 scales, each scale maturing berry-like, oval, about 20 mm long and 10–15 mm broad, red to purple-red with a soft edible pulp covering the single seed. The seeds are dispersed by the Kererū (New Zealand Pigeon), which eats the very conspicuous 'berries' and passes the seeds in its droppings. It is found growing on both lowland terrain and on hill slopes throughout the two main islands as well as on Stewart Island/Rakiura (47° S).

Miro (Suebian king)

Miro (Mir, Mirio, Latin: Mirus) was the Suebian King of Galicia from 570 until his death in 583. His reign was marked by attempts to forge alliances with other Chalcedonian Christian nations with the goal of checking the power of the Arian Visigoths under Leovigild. During his reign relations were established with both Francia and the Byzantine Empire and the kingdom reached its zenith, but it collapsed within three years of his death.

Miro enjoyed good relations with the Church during his reign. In 572 he called the Second Council of Braga, a supplementary council to the First Council of Braga of 561. It has even been suggested, based on the lack of a signatory for the diocese of Dumio in the concilar acts, that Miro himself may have represented that see.

Miro also maintained "intimate and friendly" relations with Martin of Dumio, the Archbishop of Braga and Metropolitan of Gallaecia. Martin's principal work, Formula Vitae Honestae, is dedicated to him, and the Exhortatio Humilitatis, printed among Martin's works, is also probably addressed to him. Indeed, Martin advised Miro's counsellors to read his Formula so as to be able better to counsel the king.

Greeks (finance)

In mathematical finance, the Greeks are the quantities representing the sensitivity of the price of derivatives such as options to a change in underlying parameters on which the value of an instrument or portfolio of financial instruments is dependent. The name is used because the most common of these sensitivities are denoted by Greek letters (as are some other finance measures). Collectively these have also been called the risk sensitivities,risk measures or hedge parameters.

Use of the Greeks

The Greeks are vital tools in risk management. Each Greek measures the sensitivity of the value of a portfolio to a small change in a given underlying parameter, so that component risks may be treated in isolation, and the portfolio rebalanced accordingly to achieve a desired exposure; see for example delta hedging.

The Greeks in the Black–Scholes model are relatively easy to calculate, a desirable property of financial models, and are very useful for derivatives traders, especially those who seek to hedge their portfolios from adverse changes in market conditions. For this reason, those Greeks which are particularly useful for hedging—such as delta, theta, and vega—are well-defined for measuring changes in Price, Time and Volatility. Although rho is a primary input into the Black–Scholes model, the overall impact on the value of an option corresponding to changes in the risk-free interest rate is generally insignificant and therefore higher-order derivatives involving the risk-free interest rate are not common.

Gamma (store)

Gamma is a Dutch Hardware store-chain. It started in May 11, 1978 in Breda. The headquarters of the franchise-organisation Intergamma is located in Leusden and as of 2011 it has 245 stores, of which 164 are located in the Netherlands and 81 in Belgium. Intergamma also owns the Hardware store-chain Karwei.

History

In 2008 Gamma had a revenue of 606 million euro.

Gamma commercials have been broadcast in the Netherlands on radio and television since 1994, and have made the actors John Buijsman and Martin van Waardenberg well known in the Netherlands. In Flanders Luk Wyns is the face of the company.
