BAE Systems Nimrod MRA4

The BAE Systems Nimrod MRA4 was a maritime patrol and attack aircraft intended to replace the Hawker Siddeley Nimrod MR2. The rebuilt aircraft would have extended the operating life of the Nimrod fleet by several decades and significantly improved the aircraft by installing more efficient Rolls-Royce BR700 turbofan jet engines to almost double the flight range. The conversion of the flight deck to a digital glass cockpit would have simplified control operations and reduced crew requirements. New detection systems were to be installed, as well as additional weapons for anti-submarine warfare.

However the project was subject to significant delays due to cost over-runs and contract re-negotiations. This was partly due to difficulties combining refurbished Nimrod MR2 fuselages, which had not been built to a common standard, with newly built wings. The numbers of aircraft to be procured fell from 21 to nine over a course of years, while costs continued to climb.

The MRA4 was ultimately cancelled in 2010 as a result of the Strategic Defence and Security Review, at which point it was £789 million over-budget and over nine years late. There is no direct replacement under development. The roles intended for the MRA4 are filled by existing assets such as the Type 23 Frigate and the Merlin helicopter.

Female

Female (♀) is the sex of an organism, or a part of an organism, that produces non-mobile ova (egg cells). Most female mammals, including female humans, have two X chromosomes.

Defining characteristics

The ova are defined as the larger gametes in a heterogamous reproduction system, while the smaller, usually motile gamete, the spermatozoon, is produced by the male. A female individual cannot reproduce sexually without access to the gametes of a male (an exception is parthenogenesis). Some organisms can reproduce both sexually and asexually.

There is no single genetic mechanism behind sex differences in different species and the existence of two sexes seems to have evolved multiple times independently in different evolutionary lineages. Patterns of sexual reproduction include

Plant reproductive morphology

Plant reproductive morphology is concerned with the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.

Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants (green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination process involved both biotic and abiotic interactions. Charles Darwin's theories of natural selection utilized this work to build his theory of evolution, which includes analysis of the coevolution of flowers and their insect pollinators.

Female (1933 film)

Female is a 1933 Warner Bros. Pre-Code film directed by Michael Curtiz and starring Ruth Chatterton and George Brent. It is based on the novel of the same name by Donald Henderson Clarke.

Plot

Alison Drake (Ruth Chatterton) is the wealthy owner and hard-driving, no-nonsense head of a large automobile company, inherited from her father. Her work has caused her to lose her youthful romanticism, and she has casual affairs with men, including her own employees.

Alison hosts a party at her mansion, but becomes fed up with the men out to either sell her things or marry her for her money. She dresses down and goes to an amusement park, where she picks up a man at a shooting gallery. They have fun together, but he refuses her offer to go home with him.

The next day, they meet again at her factory. To their mutual astonishment, he turns out to be Jim Thorne (George Brent), a gifted engineer she has ordered her underlings to hire away from her competition. Saying that she has no time now, Alison has him come to her mansion that night, supposedly to discuss his plans for the company in detail. She attempts to seduce him, but he rejects her as anything other than his employer.
