Río Cachapoal () is a river in Chile. It is in the Region of O'Higgins. The river gives the name to the Province of Cachapoal.
O'Higgins Region
The VI Libertador General Bernardo O'Higgins Region (), often shortened to O'Higgins Region, is one of Chile's 15 first order administrative divisions. It is named in honour of Bernardo O'Higgins Riquelme, one of Chile's founder.
The capital and largest city of the region is Rancagua. The second major city is San Fernando.
In 1880, the old "O'Higgins Province" was created with the territory of the present Cachapoal Province. In 1974, with the creation of the Regions of Chile, it became, together with the Colchagua Province, the new Region VI, known since then as Libertador General Bernardo O'Higgins Region.
The O'Higgins Region is bordered to the west by the Pacific Ocean, to the east by Argentina, to the north by the Valparaíso and Santiago Metropolitan Regions, and to the south by the Maule Region.
The main rivers are the Cachapoal and Tinguiririca.
, there were (estimated) 918,751 persons living in the region, for a population density of inhabitants/km².
The largest city in the region is its capital, Rancagua, with 206,971 inhabitants (2002 census). Other cities are San Fernando (49,519) and Rengo (30,891).
The O’Higgins region is divided in three provinces: Cachapoal, Cardenal Caro and Colchagua.
Cue stick
A cue stick (or simply cue), is a kind of stick used for sports like pool, snooker and carom billiards. It is used to hit a ball, normally the "cue ball". Cues are fixed-up sticks, normally about 58 inches (1.5 m) long and 18–21 ounces (510–600 g). Most cues are made of wood, but sometimes the wood is covered with other materials like carbon fiber or fiberglass. An old term for a cue, used from the 16th to early 19th centuries, is "billiard stick".
Accumulator
The accumulator is the register for storing results of operations inside the CPU. Accumulator's name or representation depend upon CPU architecture and manufacturer, for example in intel x86 architecture accumulator's name is AX in 16bits or EAX in 32bits mode. An accumulator is manipulated by machine code or assembly for example assembly code:
"add ax, 3" add 3 in accumulator register.
OCaml
Objective Caml (OCaml) is a programming language which is a dialect of ML (programming language). It extends the Caml language so object-oriented programming can be used.
Structured Query Language
Structured Query Language (SQL) is a language used to view or change data in databases. The statements used in this language are called SQL queries.
Basic use of SQL queries is, to:
This is a simple SQL Query which is used to show all values stored in column named 'my_column' from the data table named 'my_table'.
SELECT my_column FROM my_table;
Here is an example of inserting new information into a table called 'people.'
The query first specifies the table as 'people', then the columns in which data is going to be inserted into, and the data that is going into these columns. As a result, data will be added into the columns in the same order the column names are listed in the first brackets: (first_name, last_name, age, favorite_food).
INSERT INTO people (first_name, last_name, age, favorite_food) VALUES ("Bob", "Page", "42", "Hamburgers");
In the example below the columns aren't listed. This would result in an attempt to add the data into the table in the order the values are listed.
INSERT INTO people VALUES ("Bob", "Page", "42", "Hamburgers");
Doing the above (without naming the columns) might result in inputting the data in an incorrect column or the statement might not run correctly - when the value types are mismatched (for example trying to input a word into a column storing only numbers).
Provinces of Chile
A province is the second largest administrative division in Chile, after a region. Each region is divided in provinces. Chile has 54 provinces in total. Each province is ruled by a governor ("gobernador") designated by the president. The provinces are also divided into communes which are ruled by a municipality.

Kashmir flycatcher
The Kashmir flycatcher ("Ficedula subrubra") is a small passerine bird in the flycatcher family Muscicapidae.
This species breeds in the north-west Himalayas in the Kashmir region of the Indian subcontinent. It is migratory and spends the winter in the hills of central Sri Lanka and the Western Ghats of India.
This bird eats insects. It is about 13 centimetres long. The male has a grey-brown back with an orange-red throat, breast and sides. It is bordered with black on the throat and breast. Females and first-winter birds have slightly browner upperparts. The red of the underparts may be just a light pink.
Calliostoma
The Top shells (which are called Calliostoma) are marine gastropod molluscs. They can be found world-wide. The name of this genus is derived from the Greek words "kallos" (beautiful) and "stoma" (mouth), referring to the pearly aperture.
Corvette
A corvette is a small, manageable and lightly armed war ship. During the Age of the Sail, corvettes were smaller than frigates and larger than sloops-of-war, they had normally a single gun deck. Almost all the modern navies use ships smaller than frigates for coastal duty, but not all of them use the term "corvette" (from the French "corvair") or equivalent.
Sparrowhawk
The sparrowhawk ("Accipiter nisus") is a small bird of prey in the family Accipitridae. It has a wide distribution in Eurasia and north Africa.
The adult male sparrowhawk has a blue-grey back and wings. His chest and belly have thin orange stripes. Female and young sparrowhawks have brown backs and wings, with thin brown stripes. The female is up to 25% larger than the male. This is one of the biggest size differences in any bird species.
The sparrowhawk eats mostly small birds which live in woodland. It can be seen in any habitat and often hunts birds in town and city gardens. Male sparrowhawks eat smaller birds like tits, finches and sparrows. Females eat bigger birds like thrushes and starlings. They can kill birds weighing more than .
The sparrowhawk is seen in Europe, parts of Asia and parts of Africa. Birds that breed in the north migrate south for winter. Birds that live further south stay there, or fly shorter distances.
Sparrowhawks build a nest in woodland. The nest is up to 60 cm (2.0 ft) wide and made from twigs. The female lays four or five eggs with pale blue shells. The chicks hatch after 33 days and leave the nest after another 24 to 28 days.
The proportion of young sparrowhawks which survive to one year old is 34%. More young males die than young females. 69% of adults survive from one year to the next. The average lifespan is four years.
The number of sparrowhawks decreased in Europe in the 1950s. Chemicals to kill unwanted insects ("pesticides") were put on seeds before they were planted. Small birds ate the seeds and then sparrowhawks ate the small birds. The amount of chemicals in the food chain increased. This affected the sparrowhawks. Some were poisoned and others laid eggs with shells that were too thin. The shells broke before the chicks hatched. The pesticides were banned and the sparrowhawk population increased again. It is now one of the commonest birds of prey in Europe.
The sparrowhawk's hunting behaviour means people who own homing pigeons or keep birds for food may dislike it. Some people also blame the sparrowhawk for decreases in the numbers of smaller birds. Scientists have found that increased numbers of sparrowhawks did not reduce the numbers of birds living in farmland and woodland in the 1960s. Research in Scotland found that less than 1% of homing pigeons that died were killed by sparrowhawks.
