Oka's lemma

In mathematics, Oka's lemma, proved by Kiyoshi Oka, states that in a domain of holomorphy in Cⁿ, the function –log d(z) is plurisubharmonic, where d is the distance to the boundary. This property shows that the domain is pseudoconvex.

Oka cheese

Oka is a semi-soft washed rind cheese that was originally manufactured by Trappist monks located in Oka, Quebec, Canada. The cheese is named after the town. It has a distinct flavour and aroma, and is still manufactured in Oka, although now by a commercial company. The rights were sold in 1996 by Les Pères Trappistes to the Agropur cooperative. It is also manufactured in Holland, Manitoba, by Trappist Monks at the Our Lady of the Prairies Monastery, which is located 8 miles southeast of Holland.

It originated in 1893. Since that time, Quebec has become a major producer of Canadian Cheese. Oka cheese has a pungent aroma and soft creamy flavour, sometimes described as nutty and fruity. The cheese, which is made from cow's milk is covered with a copper-orange, hand-washed rind. Its distinct flavour sets it apart from more common cheeses such as colby and cheddar, and does not go through a cheddaring process.

There are four types of Oka cheese, regular, classic, light and providence. 'Regular' Oka can be made from both pasteurized and raw cow's milk. It is a pressed, semi-soft cheese that is surface ripened for some 35 days. The 'Classic' is ripened for an additional month. Aging is done in refrigerated aging cellars. The cheese rounds are placed on cypress slats and the cheeses are periodically turned and hand washed in a weak brine solution. 'Providence' Oka is of a much more creamy and soft texture then either 'Classic' or 'Regular', while 'Light' is similar to 'Regular', but with a lower percentage of fat.

Lemma (botany)

Lemma is a phytomorphological term used in botany referring to a part of the spikelet of grasses (Poaceae). It is the lowermost of two chaff-like bracts enclosing the grass floret. It often bears a long bristle called an awn, and may be similar in form to the glumes - chaffy bracts at the base of each spikelet. It is usually interpreted as a bract but it has also been interpreted as one remnant (the abaxial) of the three members of outer perianth whorl (the palea may represent the other two members, having been joined together).

A lemma's shape, their number of veins, whether they are awned or not, and the presence or absence of hairs are particularly important characters in grass taxonomy.

Lemma (morphology)

In morphology and lexicography, a lemma (plural lemmas or lemmata) is the canonical form, dictionary form, or citation form of a set of words (headword). In English, for example, run, runs, ran and running are forms of the same lexeme, with run as the lemma. Lexeme, in this context, refers to the set of all the forms that have the same meaning, and lemma refers to the particular form that is chosen by convention to represent the lexeme. In lexicography, this unit is usually also the citation form or headword by which it is indexed. Lemmas have special significance in highly inflected languages such as Arabic, Turkish and Russian. The process of determining the lemma for a given word is called lemmatisation. The lemma can be viewed as the chief of the principal parts, although lemmatisation is at least partly arbitrary.

Morphology

In English, the citation form of a noun is the singular: e.g., mouse rather than mice. For multi-word lexemes that contain possessive adjectives or reflexive pronouns, the citation form uses a form of the indefinite pronoun one: e.g., do one's best, perjure oneself. In languages with grammatical gender, the citation form of regular adjectives and nouns is usually the masculine singular. If the language additionally has cases, the citation form is often the masculine singular nominative.

Lemma (album)

Lemma is an album composed by John Zorn and featuring violinists David Fulmer, Chris Otto and Pauline Kim which as recorded in New York City in 2012 and released on the Tzadik label in February 2013.

Reception

Martin Schray stated "Although John Zorn has been widely acclaimed for his music, his compositions in the field of new classical music deserve more attention".
