Bioavailability

In pharmacology, bioavailability (BA) is a subcategory of absorption and is the fraction of an administered dose of unchanged drug that reaches the systemic circulation, one of the principal pharmacokinetic properties of drugs. By definition, when a medication is administered intravenously, its bioavailability is 100%. However, when a medication is administered via other routes (such as orally), its bioavailability generally decreases (due to incomplete absorption and first-pass metabolism) or may vary from patient to patient. Bioavailability is one of the essential tools in pharmacokinetics, as bioavailability must be considered when calculating dosages for non-intravenous routes of administration.

For dietary supplements, herbs and other nutrients in which the route of administration is nearly always oral, bioavailability generally designates simply the quantity or fraction of the ingested dose that is absorbed.

Bioavailability is defined slightly differently for drugs as opposed to dietary supplements primarily due to the method of administration and Food and Drug Administration regulations.

Active (1877)

The Active was a wooden ketch that was wrecked on the Oyster bank at the entrance of Newcastle Harbour, New South Wales, near the previously wrecked Colonist on 19 January 1898 while carrying a cargo of ironbark to Morpeth, New South Wales under the command of Captain P. Williams. There were no casualties but the ship was lost. The wreck has not been located, but the approximate co-ordinates of the shipwreck are 32°55′S 151°47′E / 32.92°S 151.79°E / -32.92; 151.79Coordinates: 32°55′S 151°47′E / 32.92°S 151.79°E / -32.92; 151.79.

Ibacus peronii

Ibacus peronii, the Balmain bug or butterfly fan lobster, is a species of slipper lobster. It lives in shallow waters around Australia and is the subject of small-scale fishery. It is a flattened, reddish brown animal, up to 23 cm (9 in) long and 14 cm (6 in) wide, with flattened antennae and no claws.

Description

In common with other slipper lobsters, Ibacus peronii has a broad, flattened body and a large carapace. The carapace is reddish brown, and reaches lengths of 2–8 centimetres (0.8–3.1 in), with the whole animal able to reach a length of 23 cm (9 in), and a width of 10–14 cm (3.9–5.5 in). The antennae are also short and broad, and the flattened form of the whole animal allows it to partly bury itself in soft substrates. There are no claws on the five pairs of legs. Captured animals typically weigh around 120 grams (4.2 oz), but the weight can range from 80 to 200 g (2.8 to 7.1 oz).

The species is sometimes confused with the Moreton Bay bug, Thenus orientalis, but they can be distinguished by the placement of the eyes: the eyes of I. peronii are near the midline, while those of T. orientalis are at the margin of the carapace.

Kalanchoe tetraphylla

Kalanchoe tetraphylla (also known as paddle plant, flapjacks, desert cabbage, white lady, geelplakkie, meelplakkie, or plakkie ) is a species of Kalanchoe native to South Africa. A succulent plant producing a stalk about 1m tall, dying back after flowering. It forms a basal rosette of large, rounded, fleshy, stalkless leaves, which are grayish-green with red margins, covered with a white powdery bloom. The inflorescence is terminal and erect with densely clustered thyrse-like panicles of greenish waxy flowers with yellow recurved lobes, narrowly urn-shaped. The plant flowers from autumn to spring, and is common in grassveld amongst rocks.
