Ecology

Ecology (from Greek: οἶκος, "house", or "environment"; -λογία, "study of") is the scientific analysis and study of interactions among organisms and their environment. It is an interdisciplinary field that includes biology, geography and Earth science. Ecology includes the study of interactions organisms have with each other, other organisms, and with abiotic components of their environment. Topics of interest to ecologists include the diversity, distribution, amount (biomass), and number (population) of particular organisms, as well as cooperation and competition between organisms, both within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and various niche construction activities, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits, and the variety of organisms is called biodiversity. Biodiversity, which refers to the varieties of species, genes, and ecosystems, enhances certain ecosystem services.

Eco (video game)

Eco is a wire-frame 3D evolution life simulation game developed by Denton Designs for the Amiga and Atari ST. It was released in 1988 and published by Ocean Software.

The player initially uses mouse or joystick to control an insect, which must avoid predators, find some food, and then find another insect of the same species and mate with it. The player can then unlock one of several "genes", altering the value of which changes their creature. Some changes are only cosmetic and leave the creature in the same species; others can, for instance, make the initial insect a new species with wings and capable of flight. After unlocking multiple genes the player can become a fast dog-like quadruped, a bird, a scorpion or a humanoid. The game does not end until the player starves, is killed by another creature, or deliberately "evolves" into a plant.

Week

A week is a time unit equal to seven days. It is the standard time period used for cycles of work days and rest days in most parts of the world, mostly alongside (but not strictly part of) the Gregorian calendar.

The days of the week were named in different languages after classical planets, various deities (example: Thursday – Thor's day, a variation after Jupiter's day from Roman times) and heavenly bodies (example: Sunday – Sun's day) and other sources. In English, the names are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.

ISO 8601 includes the ISO week date system, a numbering system for weeks within a given year – each week begins on a Monday and is associated with the year that contains that week's Thursday (so that if a year starts in a long weekend Friday–Sunday, week number one of the year will start after that).

The term "week" is sometimes expanded to refer to other time units comprising a few days, such as the nundinal cycle of the ancient Roman calendar.

Week!

"Week!" is the ninth single by Do As Infinity, released in 2001. The B-side, "Tsuredzure Naru Mama ni", is the only studio-recorded song by the guitarist Ryo Owatari, who also wrote the lyrics. The melody parallels that of song "Yesterday & Today". It was used as the theme song for the drama Yome wa Mitsuboshi.

This song was included in the band's compilation albums Do the Best and Do the A-side.

Gross domestic product

Gross domestic product (GDP) is a monetary measure of the value of all final goods and services produced in a period (quarterly or yearly). Nominal GDP estimates are commonly used to determine the economic performance of a whole country or region, and to make international comparisons. Nominal GDP however do not reflect differences in the cost of living and the inflation rates of the countries; therefore using a GDP PPP per capita basis is arguably more useful when comparing differences in living standards between nations.

GDP is not a complete measure of economic activity. It accounts for final output or value added at each stage of production, but not total output or total sales along the entire production process. It deliberately leaves out business-to-business (B2B) transactions in the early and intermediate stages of production, as well as sales of used goods. In the United States, the Bureau of Economic Analysis (BEA) has introduced a new quarterly statistic called gross output (GO), a broader measure that attempts to add up total sales or revenues at all stages of production.Mark Skousen was the first economist to advocate GO as an important macroeconomic tool. Other countries are following suit, such as the United Kingdom, which now producing an annual statistic called Total Output.
