First, the Romans stood their ground and used volleys of "pila" (heavy javelins) to kill thousands of Britons who rushed toward the Roman lines. The Roman soldiers engaged Boudica's second wave in the open. As the Romans advanced in a wedge formation, the Britons attempted to flee, but were impeded by the presence of their own families. They had put their people in wagons at the edge of the battlefield, and were slaughtered.
Tacitus reports that "according to one report almost eighty thousand Britons fell" compared with only four hundred Romans. Boudica fled, and her time and place of death is not known.
The Prefect Postumus, on hearing of the Roman victory, fell on his sword. Fearing Suetonius' actions would provoke further rebellion, Nero replaced the governor with the more conciliatory Publius Petronius Turpilianus. The historian  Gaius Suetonius Tranquillus tells us the crisis had almost persuaded Nero to abandon Britain.
Choir (music)
A choir or choral group is a collection of people who sing together. They typically rehearse together with a leader and perform concerts or sing during religious services. Some choirs are professional (the singers are paid for their work in the choir). Some choirs are semi-professional (the leaders are paid at a professional rate for their work with the choir but the singers are not). Some choirs are amateur or recreational (the leaders are either not paid or are offered an honorarium and the singers are not paid). Some amateur choirs invite anyone who is interested sing with them. Professional, semi-professional, and some amateur or recreational choirs require interested people to audition and then select their members based on a set of audition criteria.
The singers in choirs are grouped by their voice types and choral music is usually written with distinct lines or parts for some or all of these voice types. Voice types are typically organized into four groups. From highest vocal range to lowest, these include:
Music composed for choirs, or choral music, usually has at least two distinct vocal lines or parts that create harmony with one another. Although four vocal ranges are typically specified, composers of choral music often write more than four vocal lines. If the music divides into more than four parts this subdivision is typically shown by repeating the initials of the four voice parts to show which singers should be assigned to these vocal lines, e.g. SSAATTBB (for music in eight parts: two soprano lines, two alto lines etc.). Young children’s choirs may be unison choirs (all singing the same line), but older children will sing in two (SS) or three (SSA) parts or more.
Choirs usually organize and limit themselves according to voicing and/or age of the singers as well as by the size of group or the type of music they sing.
The primary voicing categories are:
Choirs that organize themselves by size or repertoire type, they can be called:
The word choir can also mean the part of a church or cathedral where the choir sit. The choir is between the nave (the main body of the church) and the sanctuary (where the altar is). The singers will divide into two groups and sit facing one another on either side of the choir area in the “choir stalls”. In cathedrals the singers on the left (when facing the altar) are called “cantoris” and those on the right are called “decani” (pronounce: dee-CAY-nye).
A large pipe organ may have three or more manuals (keyboards). The third keyboard is called the "choir". Traditionally the sound from the choir organ comes from pipes in a separate box behind the organist, facing the choir (the singers). It is often used to accompany them.
Originally it was a separate instrument so that the organist had to turn round to play it. Later it became possible for the organist to play it from the main console.
Some famous choirs include:
Motherboard
The motherboard, also known as a mainboard, is the main circuit board in any electronic system. It's what holds together all the components needed for an electronic system to function. Although there may be other circuit boards attached to the motherboard, the motherboard is the largest of them all.
The painted, base material of a motherboard is composed of fiberglass yarn strands that have been woven together and coated with a liquid resin, and then set to dry. This combination of woven fiberglass and resin is sent through an oven at a high temperature. When it comes out, it hardens and becomes stronger than it was before. This finished, very-hard, lightweight material, called pre-preg, is layered together and then painted, typically green. It forms what is the base material of the motherboard. This material acts as an electrical insulator and holds everything in place.
Copper is used to form the communication pathways that connect all the different parts on the motherboard, and is used because of its excellent ability to conduct electricity.
“On-board” is a term used to refer to anything that is permanently embedded onto the motherboard. Electrical parts are soldered onto the motherboard. These parts include transistors and resistors. Other parts that are attached to the motherboard are able to be removed in the future so that they can be upgraded. The CPU is an example of a part that is usually removable.
Parts that are not "on-board" can be bought as a card. Some of these parts include RAM and CPU. Computers today usually have a memory port, 2 or more USB ports, a parallel port (for use with old printers usually), audio & microphone jacks, a network port and ports for the keyboard and mouse. There are also some rare motherboards that have plugs only for very specific parts.
All of the slots and plugs both inside and outside the computer case are shaped a certain way to accept a certain type of part. Some will not even accept parts even one generation behind, such as the CPU and memory. Others, like the video plug have not changed in years. Some of the plugs, such as the video, keyboard and mouse plugs, are a special color. These colors make it easier to pair the plug to the port. The motherboard is also may also be referred to as the PCB which stands for ‘printed circuit board’, though it is essentially a gigantic PCB and can be considered the 'primary' PCB.
High-definition television
High-definition television (HDTV) is a new television broadcasting system which uses a higher resolution than a normal television. With HDTV, people can watch television in higher quality than old television, giving a more vivid and clear screen.
Most HDTV systems use digital signals with a 16:9 aspect ratio (width to height). This is different to SDTV (standard-definition television) which uses analog signals and a 4:3 aspect ratio.
HDTV picture resolution is at least twice that of SDTV, so it can present a more vivid screen than analog television or DVD. HDTV can control resolution efficiently.
Some videos on the website YouTube, a free video sharing website that lets people upload and view videos, are in HD.
There are different standards. Common ones are:
As a comparison, PAL plus is at 1024x576 pixels, and NTSC at 853x480 pixels.
