The population of bush elephants has drastically declined in the last thirty years. It is hunted for its ivory and meat. Protection by game wardens has been only partly successful.
This large elephant is well adapted to the grassland plains of East Africa, and it is sometimes called the African savannah elephant.
The African bush elephant occurs in Sub-Saharan Africa including Uganda, Kenya, Tanzania, Botswana, Zimbabwe, Namibia, Zambia, and Angola.
It moves between a variety of habitats. These include subtropical and temperate forests, dry and seasonally flooded grasslands and woodlands, wetlands and agricultural land from sea level to mountain slopes. In Mali and Namibia, it also lives at times in desert areas.
Binda, New South Wales
Binda is a village in the Southern Tablelands region of New South Wales, Australia in Upper Lachlan Shire.
It is about 261 km south-west of Sydney and 19 km north of Crookwell. Other near-by towns or locations are:
In 2006, the population of Binda was 131 people.
The word Binda is thought to be from the Gandangara Aboriginal word for deep water.
The first Europeans in the Binda area were the explorers James Meehan and John Oxley in 1820. People began living in the area in the 1840s. Police were based at Binda in 1840 to protect local farmers from bushrangers. The town was begun in 1851. Blocks of land in the town were made ready for sale in 1852. It was the first town in the area to have a school, post office, police station and a courthouse. At Funny Hill, a sheep farm, a racing track for horses was made and the Binda Picnic Races began in 1848.
On Boxing Day, December 26, 1864, the bushrangers Ben Hall, John Gilbert and John Dunn rode into the town with 3 local girls. They robbed a shop owned by Edward Morriss. They locked all the local people into the Flag Hotel. They made everyone dance to celebrate Boxing Day. Morriss got out of the hotel at 2.00 a.m. and set off to tell the police. Hall set fire to Morriss's shop and burned it down.
Hollister can mean:
Hollister Co. is a clothing company owned by Abercrombie & Fitch. The kind of clothing they sell is "casual", meaning that it is for informal use. It also has a theme based on the surfing cultural movement of Southern California. The first Hollister store opened in July 2000 in Columbus, Ohio. Even though Hollister opened in 2000, many of their items say it was created in 1922. This is based on a story that is not real. On October 25, 2008 Hollister opened the first store outside the U.S. and Canada in Brent Cross, London.

Fire services in the United Kingdom
The fire service in the United Kingdom operates under separate legislative and administrative arrangements in England, Northern Ireland, Scotland and Wales.
In England, there is a fire service for each county and large city, although some cover two counties. Wales is divided between three fire services. Scotland has had only one fire service since 2013. Northern Ireland has had only one fire service since 1973.
Fire services are known as "fire and rescue services", or "fire services" for short, or by the older phrase "fire brigades". Most of them now have the name "[Place] Fire and Rescue Service", e.g. Oxfordshire Fire and Rescue Service. There are a few that do not: London Fire Brigade, Cleveland Fire Brigade and West Midlands Fire Service.
There are two main types of firefighter:
Some fire stations are day-crewed, meaning they are covered by wholetime firefighters during the day and by retained firefighters at night. A few places have volunteer firefighters, who are like retained firefighters but are not paid at all.
Wholetime firefighters work as part of a 'watch'. This is a group of 5-15 firefighters who work the same hours at the same fire station. A fire station's watches are usually named with a colour (e.g. red watch, white watch, blue watch, green watch).
The fire service has ranks. In most fire services, these are, from lowest to highest:

Zub
Zub is a computer game made for use on the Commodore 64 and ZX Spectrum computers which was released in 1986 by Mastertronic. The code was written by John and Ste Pickford on the ZX Spectrum and Phillip Brian Allsopp on the Commodore 64, and the music was composed by David Whittaker.
Zub works for the Emperor Zub of the Zub galactic empire and must find the Green Eye of Zub. Zub has been permitted to use the Ancient Intergalactic Elevators which take him to other planets. The elevators can only be reached by jumping and riding on platforms to reach the top of the sky. The platforms and elevators are guarded by creatures (also known as Zubs) but each planet has a different sub-species - for example the first level's Zub resembles a gyroscope whilst he fourth level Zub is a fish. The Zubs can be shot and stunned. They will float to the top of the sky where the recover and return to attack Zub again. The Green Eye of Zub was located on the tenth planet and once the Eye is found, Zub has to return to the first planet to give the Eye of Zub to Emperor Zub.
There are seven difficulty levels, each one increases the number of enemy Zubs per planet.
Northern Italy
Northern Italy ("Italia Settentrionale", "Italia del Nord", "Padania", "Alta Italia", "Norditalia" or just "Nord") is an area that is made up of two areas in Italy:
Northern Italy is more a business area compared to the south and is colder. People from the south sometimes emigrate to the north because of this.
This region has 26,835,082 inhabitants and an area of 46,301 mi² (119,921 km²). The largest city is Milan. It is generally seen as having a higher wealth than the southern regions of Italy. This is due to the 'North-South' Divide which is said to split the country in half in terms of means of development.
Thermosphere
The thermosphere is the fourth layer of the Earth's atmosphere. It is directly above the mesosphere (middle layer) and directly below the exosphere (top layer).
The name thermosphere is taken from the Greek word "thermos" which means 'heat'. This layer has high temperatures because it absorbs X-rays and extreme ultraviolet radiation from the Sun. Even though it has temperatures of 2,000 °C (3,360 °F), the density of the thermosphere is so low that it doesn't feel hot. The absorbed ionizing radiation also creates the ionosphere. Shortwave radio waves can bounce off the Kennelly-Heaviside layer (ionosphere) and go to distant parts of the Earth. This layer is very helpful in radio communication.
Anaconda (installer)
Anaconda is the installer for Red Hat Linux and Fedora. It is written in Python and C, with a graphical interface using GTK+ 3 and PyGObject and a text inetrface using python-newt. A kickstart file can be used to automatically configure the installation, allowing users to run it without much supervision.
Anaconda is used by RHEL, Fedora and a number of other projects, Anaconda offers a text-mode and GUI mode, so users can install on a wide range of systems.
Anacondas are lizard-eating boas, and the Caldera installation program was called "Lizard", hence this name was chosen.
Canowindra, New South Wales
Canowindra (pronounced Can-noun-dra) is an historic town near Cowra in the central west of New South Wales, Australia. Canowindra is on the Belubula River.
A post office opened in 1847. The mail came through Carcoar. It was not part of the road to the Lachlan because it didn't have a bridge.
In October 1863, bushranger Ben Hall's gang took over the village for three days. Everyone was held hostage in the hotel. The gang held a big party for everyone in the hotel. A monument to Ben Hall was put up in 1951 on the site of Robinson's hotel, the "Travellers' Rest". New research shows that the events happened at an hotel on the other side of the river.
The Royal Hotel is on the site of another hotel owned by Robinson. A sign on the wall says this was where Ben Hall's gang had their party. Other important buildings include the nursing home, the Junction Hotel, Finn's Building, the Victoria Hotel, the former Bank of NSW and the former CBC Bank. The Trading Post is a homewares shop that won a tourism award for 2006.
Canowindra is also known as the Balloon Capital of Australia. One of the largest festivals in Australia used to take place here every April. This was called Marti's Fiesta, which is no longer held due to lack of money.
Australian country music star Captain Flange makes his home in Canowindra.
The town is the site of one of the world's great fossil discoveries. A road worker in 1956 found 360 million year old fish fossils. These were from the Devonian period in the Palaeozoic era. The "Canowindra slab" was taken to the Australian Museum, Sydney. The fish had been trapped in a pool of water that dried up. The fish found were two armoured antiarch placoderms, "Remigolepis walkeri" and "Bothriolepis yeungae." They also found "Canowindra grassi", a lobe-finned crossopterygian fish, with two rare young arthrodire placoderms, "Groenlandaspis" species.
More fossils were found in January 1993 using an excavator to dig down to the fossil layer. Many fish were preserved in detail. Specimens can be seen in the Age of Fishes Museum. This was built with support and funding from the Australian Museum. The Canowindra site has now been listed as part of Australia's National Heritage because of its international scientific importance.
Robert Cutler
Robert Cutler (1895 – 1974) was a U.S. administrator. He served as National Security Advisor between 1953 and 1955, and again from 1957 to 1958. A graduate of Harvard College and Harvard Law School and attorney and bank executive in Boston, Massachusetts before taking public office, he was the person to serve in the newly created position of National Security Advisor during the Eisenhower Administration.
St. Anthony-Chapel
The St. Anthony-Chapel is a chapel in the district Kornelimünster of the German city of Aachen.
It was built in 1718 but destroyed by an earthquake a short time later. The abbot of the abbey at Kornelimünster ordered to rebuild the damaged building. It was completed in 1781.
The St. Anthony-Chapel belongs to a group of five chapels of Kornelimünster.

The Bushwackers (band)
The Bushwackers Band was first called the Bushwackers and Bullockies Band. It is an Australian folk and country music band. It was active from the early 1970s to 1984. The group started as a trio playing around Latrobe University, Melbourne. The players were Dave Isom, Jan Wositzky and Bert Kanahoff. Their first album, "The Shearer's Dream" was made in 1974 with Dobe Newton on lagerphone and vocals, Mick Slocum on accordions and vocals, Jan Wositzky on harmonica, bush bass and vocals, Tony Hunt on fiddle and viola and Dave Isom on guitar.
Recordings include "Faces in the Street", "Beneath the Southern Cross", "Bushfire", "Murrumbidgee" and "The Shearers Dream". some of these were made through Australian record label Astor Records. The album "And the Band Played Waltzing Matilda" was made with EMI records in 1976. It is regarded as one of their best recordings.
Many songs were settings of poetry written by Australian bush poets including Henry Lawson.
Other members and musicians who have played and recorded with the band over the years include:
In the 90's the band reformed with Newton and Corbett back in the lineup.
The band members in 2000 were:
The band members in 2008 were:

United States Department of Transportation
United States Department of War
The United States Department of War, also called the War Office, was the department of the United States government's executive branch responsible for the operation and maintenance of land (and later air) forces from 1789 until September 18, 1947, when it became part of the National Military Establishment, renamed on August 10, 1949 the Department of Defense. The War Department also had responsibility for the young nation's naval affairs until the establishment of the Navy Department in 1798.
United States Department of Commerce and Labor
The United States Department of Commerce and Labor was a Cabinet department of the United States government.
The department was created on February 14, 1903. Later, on March 4, 1913 the name changed to the Department of Commerce. Then, its bureaus and agencies specializing in labor moved to the new Department of Labor.
The department was administered by the United States Secretary of Commerce and Labor.
United States Department of Health, Education, and Welfare
The United States Department of Health, Education, and Welfare (also known as HEW) was a cabinet-level department of the United States government from 1953 until 1979. It was administered by the United States Secretary of Health, Education, and Welfare. In 1979, a separate Department of Education (ED) was created from this department, and HEW was renamed as the Department of Health and Human Services (HHS).
President Warren G. Harding proposed a Department of Education and Welfare as early as 1923, and similar proposals were also recommended by subsequent presidents, but for various reasons was not implemented. It was only enacted as part of "Reorganization Plan Number 1 of 1953", transmitted to Congress by President Dwight D. Eisenhower on March 12, 1953. HEW ran a Community Public Health Program, which was famous for its grants to cities like Chicago for rat control. It ran a Solid Waste program focused on municipal waste issues, like how to build sanitary landfills rather than dumps. It also had a radiation program under which it wrote standards on things like microwave ovens. When the EPA was created in 1970, it assumed a number of HEW’s programs that related to environmental protection, including its pesticides program and half of its radiation program.
To date, this was the only department of the U.S. government to be created through presidential reorganization authority, in which the president is allowed to create or reorganize bureaucracies as long as neither house of Congress passed a legislative veto. This power to create new departments was removed after 1962, but in the early 1980s, the Supreme Court declared legislative vetoes unconstitutional.
United States Post Office Department
The Post Office Department is the former name of the United States Postal Service when it was a Cabinet department. It was headed by the United States Postmaster General.
The Postal Service Act signed by President George Washington on February 20, 1792 established the Department. Postmaster General John McLean was the first to call it the Post Office "Department" rather than just the "Post Office." The organization became more important in the government when President Andrew Jackson asked his Postmaster General, William T. Barry, to sit as a member of the Cabinet.
During the Civil War, postal services in the Confederacy were provided by the Confederate States of America Post Office Department, headed by Postmaster General John Henninger Reagan.
The Postal Reorganization Act signed by President Richard Nixon on August 12, 1970, replaced the cabinet-level Post Office Department with the independent United States Postal Service. The Act took effect on July 1, 1971.
United States Department of Education
The United States Department of Education (also referred to as ED, for Education Department) is a Cabinet-level department of the United States government. Created by the Department of Education Organization Act (Public Law 96-88), it was signed into law by President Jimmy Carter on October 17, 1979 and began operating on May 4, 1980.
United States Department of Housing and Urban Development
The United States Department of Housing, often abbreviated HUD, is a Cabinet department of the United States federal government. Although its beginnings were in the House and Home Financing Agency, it was founded in 1965 to develop and execute policy on housing and cities. It has largely scaled back its urban development function and now focuses primarily on housing.
The department was established on September 9, 1965 when President Lyndon Johnson signed the Department of Housing and Urban Development Act into law. It stipulated that the department was to be created no later than November 8, 60 days following the date of enactment. The actual implementation was postponed until January 13, 1966, following the completion of a special study group report on the federal role in solving urban problems.
HUD is administered by the United States Secretary of Housing and Urban Development. The former administrator of the US Small Business Association, Steve Preston, was nominated to the Position of Secretary of HUD by President Bush on April 18, 2008. He was confirmed by the Senate and his public swearing in ceremony was on June 6, 2008.
United States Department of Veterans Affairs
The United States Department of Veterans Affairs (VA) is a government-run military veteran benefit system with Cabinet-level status. It is responsible for administering programs of veterans’ benefits for veterans, their families, and survivors. The benefits provided include disability compensation, pension, education, home loans, life insurance, vocational rehabilitation, survivors’ benefits, medical benefits and burial benefits.
It is administered by the United States Secretary of Veterans Affairs.
Particle accelerator
A particle accelerator, also called an atom smasher, is a machine that accelerates (speeds up) particles and makes them travel at very high speeds. Accelerators work by pushing particles like electrons, protons, or atomic nuclei (the centers of atoms) with electric fields and by steering them with magnetic fields. Their main use is to study particle physics.
The largest accelerators are used to study particles smaller than atoms; smaller accelerators are used to study atomic nuclei and make radioactive materials. There are two kinds of particle accelerators: linear accelerators and circular accelerators. Linear accelerators move the particles in a line, while circular accelerators move the particles in a circle. One example of a particle accelerator is the Large Hadron Collider at CERN. It is very big, stretching through two countries. Another example is the Tevatron in the United States. The cathode ray tube, used in 20th century televisions and computer monitors is also a simple accelerator for electrons.
When accelerated particles hit other particles such as atoms, smaller pieces come out. This helps people see particles smaller than an atom. Normally those particles cannot be seen, but they can in the particle accelerator. This is because in some ways energy and matter are the same thing. At the high speed created in these machines, some of the movement energy is changed into matter. It is the opposite process that nuclear weapons use; nuclear weapons turn matter into energy. Small amounts of antimatter are also created during the process.
The particle accelerator at CERN was set up to search for the Higgs Boson particle, which would complete the Standard Model of Particle Physics.
Particle accelerators often use very advanced technology. This makes them cost a lot of money which is usually paid by governments.
United States Secretary of Education
The United States Secretary of Education is the head of the Department of Education. The Secretary is a member of the President's Cabinet, and 16th in line of United States presidential line of succession. The United States Secretary of Education deals with Education.
In 1979, President Jimmy Carter established the Department of Education as a cabinet-level agency. Previously, Education had been handled by the Secretary of Health, Education, and Welfare, henceforth known as the Secretary of Health and Human Services.

Reconquista
The Reconquista (a Spanish and Portuguese word for "Reconquest"; Arabic: الاسترداد, "Recapturing") was a period of 800 years in the Middle Ages during which the several Christian kingdoms of the Iberian Peninsula expanded themselves (grew) by fighting the Muslim states of "al-Andalus" (Arabic الأندلس), the Muslim states on the Iberian Peninsula, and pushing them out of the peninsula.
The Reconquista began shortly after the Islamic conquest. Much of the ideology of the Reconquista was common to most Crusading: soldiers from all Christendom travelled to Iberia to fight the Muslims as an act of Christian repentance.
The Reconquista came to an end on the 2 January 1492 with the capture of Granada. The last Muslim ruler of Granada surrendered (gave up) his kingdom to Ferdinand II of Aragon and Isabella I of Castile, the Catholic kings ("los Reyes Católicos"). This event marked the end of Muslim rule in Iberia.

Nirvana (album)
Nirvana was a greatest hits album of songs by the popular American grunge band Nirvana, who disbanded in 1994 because the lead singer, Kurt Cobain died. The album was released on October 29, 2002. It was almost not released because of a lawsuit by Cobain's wife Courtney Love. This was because of a song on the album, "You Know You're Right", that Love thought would be wasted on a box-set album. She thought it would work better on one CD. Soon after the lawsuit was settled, the album was released.
India–Pakistan border
The Hindustan–Pakistan Border, known locally as the International Border (IB), is the international boundary between the Republic of India and Pakistan that demarcates the Indian states of Punjab, Rajasthan and Gujarat from the Pakistani provinces of Punjab and Sindh except for Kashmir that is disputed (Line of Control). The border resulted from the Partition of India in 1947.
Wagah, the ceremonial point of crossing between India and Pakistan lies along this border between the Indian city of Amritsar and the Pakistani city of Lahore.
The border between two countries is called an international border from Gujrat/Sindh to the Line of Control. The Kashmir region is divided by the 1949 UN ceasefire line into two parts and the de facto border dividing Pakistan-administered Kashmir from Indian-administered Kashmir has been called the Line of Control since 1972. On the south side of the border of the Jammu Division is Pakistan's Punjab border, and is called the "working boundary" by Pakistan (which is a recent term) but the "international border" by India.
Emblem of Afghanistan
The Coat of arms of Afghanistan has appeared in some form on the Flag of Afghanistan since the inception of that nation. The most notable absence was during the 1980s when a Communist regime ruled the nation, and in the late 1990s, during the rule of the Taliban.
The latest incarnation of the coat of arms has the added inscription of the shahadah in Arabic at the top. Below it is the image of a mosque with a mehrab that is facing Mecca with a prayer mat inside. Attached to the mosque are two flags, taken to stand for flags of Afghanistan. Beneath the mosque is an inscription that states the name of the nation. Around the mosque is a garland. It is white
USB hub
USB is an international standard of technology for connecting peripherals to computers and other devices that support it. An interface where a USB device can be connected is called a port. A USB hub is a special device which allows adding more USB ports. The additional ports share one USB connection to the computer; for this reason, each of them cannot carry as much data as a direct USB connection can.
A hub may be bus-powered, which means it gets all its electrical power from the computer. This makes simple wiring, but it cannot give full power to its peripherals. A self powered hub has its own power cord, and can give full power to peripherals that need it.
There are different versions of the USB standard; main difference between the version is the maximum speed that is supported. The USB standard also defines different types of USB plugs.
A USB hub is a normal USB device, which was built for a given version of the standard. Certain models may support different versions of USB, while others may not. As an example: USB 3.0 can transfer payload data at up to 4 GBits per second. USB 2.0 is limited to a transfer rate of 280 MBits per second. Connecting an USB 3.0 device to the computer using an USB 2.0 hub will limit the transfer rate to that of USB 2.0.
A digital signature or digital signature scheme is a type of asymmetric cryptography. For messages sent through an insecure channel, a good implementation of digital signature algorithm is the one that makes the receiver believe that the message was sent by the claimed sender, and trust the message.
Digital signatures are equivalent to traditional handwritten signatures in many respects; properly implemented digital signatures are more difficult to copy than the handwritten type. Digital signature are implemented using cryptography. Digital signatures can also provide acknowledgement, meaning that the signer cannot successfully claim they did not sign a message, while also claiming their private key remains secret. Digital signatures are regularly used in USA, European countries and India in government as well as private offices. In India certificate called Digital Signing Certificate (DSC) is widely used for e-filing the business related documents and income tax return filing etc.
Digital signatures are often used to implement electronic signatures, a broader term that refers to any electronic data that holds a meaning of a signature, but not all electronic signatures use digital signatures. In some countries, including the United States, and in the European Union, electronic signatures may have legal significance. In India electronic signature do not have any legal significance but digital signature does have legal validity and considered as legally valid signature as per the information technology act, 2000.
A digital signature system typically consists of two algorithms:
Two main properties are required by the digital signature system:
The GMR signature scheme:
In 1984, Shafi Goldwasser, Silvio Micali, and Ronald Rivest became the first to strictly define the security requirements of digital signature schemes. They described a hierarchy of attack models for signature schemes, they also present the GMR signature scheme. GMR scheme was proven to be secure against adaptive chosen-message attacks — even when an attacker receives signatures for messages of his choice, this does not allow him to copy a signature for a single additional message.
In their foundational paper, Goldwasser, Micali, and Rivest lay out a hierarchy of attack models against digital signatures:
They also describe a hierarchy of attack results:
The strongest notion of security, therefore, is security against existential forgery under an adaptive chosen message attack.
Key generation is the process of generating keys for cryptography. The key is used to encrypt and decrypt data whatever the data is being encrypted or decrypted.
Modern cryptographic systems include symmetric-key algorithms (such as DES and AES) and public-key algorithms (such as RSA). Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender will encrypt data with the public key; only the holder of the private key can decrypt this data.
Since public-key algorithms tend to be much slower than symmetric-key algorithms, modern systems such as TLS and its predecessor SSL as well as the SSH use a combination of the two in which:
The simplest method to read encrypted data is a brute force attack–simply attempting every number, up to the maximum length of the key. Therefore, it is important to use a sufficiently long key length; longer keys take exponentially longer time to attack, making a brute force attack invisible and impractical.
Currently, commonly used key lengths are:
In computer cryptography keys are integers. In some cases keys are randomly generated using a random number generator (RNG) or pseudorandom number generator (PRNG), the latter being a computer algorithm that produces data which appears random under analysis. Some types the PRNGs algorithms utilize system entropy to generate a seed data, such seeds produce better results, since this makes the initial conditions of the PRNG much more difficult for an attacker to guess.
In other situations, the key is created using a passphrase and a "key generation algorithm", using a cryptographic hash function such as SHA-1.
Symmetric-key algorithm
Symmetric-key algorithms is a method in cryptography. It is when the keys for decryption and encryption are exactly the same shared secret. You can generate the secret randomly, or from a password, or through a secret key-exchange procedure like Diffie-Hellman.
Symmetric-key algorithms are very important because they are faster on computers than the other kind:public-key algorithms. In public-key cryptography (asymmetric-key cryptography) the key for encryption can be given to the public with no problem, and everyone can send you secret messages. The key for encryption is "open" because, in practice, it cannot be used to get the key for decryption. This is very useful, but public-key cryptography algorithms are very slow on computers, so they are only used to send a secret key. Then symmetric-key algorithms are used for everything else because they are faster.
There are two kinds of symmetric-key algorithms, called stream ciphers and block ciphers. Stream ciphers encrypt a message as a stream of bits one at a time. Block ciphers take blocks of bits, encrypt them as a single unit, and sometimes use the answer later too. Blocks of 64 bits have been commonly used; though modern ciphers like the Advanced Encryption Standard use 128-bit blocks.
Examples of popular symmetric cyphers include Twofish, Serpent, AES (aka Rijndael), Blowfish, CAST5, RC4, TDES, and IDEA.
In history, some cryptanalysis methods exploited symmetry, so symmetric systems were less secure. Some attacks are called known-plaintext attacks, chosen plaintext attacks, differential cryptanalysis and linear cryptanalysis.
Other terms for symmetric-key encryption are secret-key, single-key, shared-key, one-key and eventually private-key encryption. This last term does not have the same meaning that the term "private key" has in public-key cryptography.
Unlike symmetric algorithms, asymmetric key algorithms use a different key for encryption than for decryption. Meaning, a user knowing the encryption key of an asymmetric algorithm can encrypt messages, but cannot calculate the decryption key and cannot decrypt messages encrypted with that key. A short comparison of these two types of algorithms is given below:
Symmetric-key algorithms are generally much less "computationally intensive" than asymmetric key algorithms. In practice, asymmetric key algorithms are typically hundreds to thousands times slower than symmetric key algorithms.
One disadvantage of symmetric-key algorithms is the requirement of a "shared secret key", with both parties holding the same copy at each end.
In order to ensure secure communications between everyone in a group of n people a total of "n"("n" - 1)/2 keys are needed, which is the total number of possible communication channels.
To limit the impact of a potential discovery by a cryptographic attacker, they should be changed regularly and kept secure during distribution and in service. The process of selecting, distributing and storing keys is known as key management, and is difficult to achieve reliably and securely.
In modern cryptosystems designs, both asymmetric (public key) and symmetric algorithms are used to take advantage of the best of both.
Asymmetric algorithms are used to distribute symmetric-keys at the start of a session. Once a symmetric key is known to all parties of the session, faster symmetric-key algorithms using that key can be used to encrypt the remainder of the session. This simplifies the key distribution problem, because asymmetric keys only have to be distributed authentically, while symmetric keys need to be distributed in both an authentic and confidential manner.
Systems that use such a hybrid approach include SSL, PGP and GPG, etc.
John Marshall
John Marshall (September 24, 1755 – July 6, 1835) was an American statesman and jurist who shaped American constitutional law and made the Supreme Court more powerful. Marshall was Chief Justice of the United States, working from February 4, 1801, until his death in 1835. He worked in the United States House of Representatives from March 4, 1799, to June 7, 1800, and, under President John Adams, was Secretary of State from June 6, 1800, to March 4, 1801. Marshall was from the Commonwealth of Virginia and a leader of the Federalist Party.
The longest working Chief Justice in Supreme Court history, Marshall ruled the Court for thirty years and was an important part of making the American legal system. His most important addition was judicial review; the power to stop laws that violate the Constitution. Marshall has been called the one that made the judicial branch special and powerful. Marshall also balanced the power between the federal and state government. He made sure the federal law was more powerful than state law and agreed with an expansive reading of the enumerated powers.
William H. Crawford
William Harris Crawford (February 24, 1772–September 15, 1834) was an important American politician, judge, and slaveowner during the early 19th century. He served as United States Secretary of War from 1815 to 1816 and United States Secretary of the Treasury from 1816 to 1825, and was a candidate for President of the United States in 1824.
In 1875, Crawford appeared on the 50 cent bill.
The town of Crawfordsville, Indiana, as well as Crawford County, Illinois; Crawford County, Iowa; Crawford County, Missouri; Crawford County, Arkansas; Crawford County, Wisconsin; Crawfordville, Georgia; and Crawford County, Georgia, are named for Crawford.
James McHenry
James McHenry (November 16, 1753 – May 3, 1816) was an early American statesman. McHenry was a signer of the United States Constitution. He was from Maryland. Fort McHenry was named for him. He was also a delegate to the Continental Congress from Maryland, and the third United States Secretary of War from January 27, 1796 to May 13, 1800, under Presidents George Washington and John Adams.
John Jay
John Jay (December 12, 1745 – May 17, 1829) was an American politician, statesman, slave owner, and diplomat. He was a Supreme Court Chief Justice and one of the Founding Fathers of the United States. Jay served in the Continental Congress and was elected President of that body. During and after the American Revolution, he was a minister (ambassador) to Spain and France, helping to fashion American foreign policy and to secure favorable peace terms from the British and French. He co-wrote the "Federalist Papers" with Alexander Hamilton and James Madison.
Jay served on the U.S. Supreme Court as the first Chief Justice of the United States from 1789 to 1795. In 1794 he negotiated the Jay Treaty with the British. A leader of the new Federalist party, Jay was governor of New York from 1795 to 1801. He was the leading opponent of slavery and the slave trade in New York. His first attempt to pass emancipation legislation failed in 1777 and failed again in 1785, but he succeeded in 1799, signing the law that eventually emancipated the slaves of New York; the last were freed before his death.
Evan Longoria
Evan Michael "Longo" Longoria is a third baseman for the San Francisco Giants. Longoria began his MLB career with the Tampa Bay Rays before being traded to the Giants in 2017. He won the 2008 American League Rookie of the Year award. In 2009, he won the Silver Slugger and Gold Glove awards for American League third basemen. Longoria once again won the Gold Glove award in 2010 and 2017.
A nucleolus (plural: nucleoli) is the part of a eukaryotic cell where ribosomes are made. Seen under a microscope, the nucleolus is a dark spot inside the cell's nucleus. It is made up of dense RNA and proteins. Prokaryotic cells also have ribosomes, but they don't make as many as eukaryotes do, and there is no visible nucleotatius. There is usually more than one nucleolus in a eukaryote cell. The nucleolus is not bounded by a membrane.
The nucleolus is made at a nucleolus organizer region (NOR), which is a chromosome region around which the nucleolus forms. Inside the nucleolus ribosomes are made. Ribosomes are molecular machines that synthesizes proteins. The ribosomes are exported through the nuclear envelope to the cytoplasm, where they do their work.
Nucleoli play a role in the cell's response to stress. They also help in the assembly of signal recognition particles. Malfunction of nucleoli can be the cause of several human diseases.

Duke Nukem 3D is a first-person shooter video game. It was made by 3D Realms and sold by Apogee Software. It was first sold on January 29, 1996. "Duke Nukem 3D" is based on the main character from the platform games "Duke Nukem" and "Duke Nukem II" which were also published by Apogee. The character is voiced by Jon St. John.
In the game, players control Duke Nukem, an action hero from Earth. Players must fight invading aliens that want to take over Earth. The game is made up of 28 levels spread over three chapters. An add-on pack called "The Plutonium Pak", later added a fourth episode of 11 new levels, new enemies, and one new weapon.
The game is a first person shooter, so the player sees the game from Duke's eyes. Instead of following the character around like a third-person shooter, Duke Nukem is like being "inside" Duke, and the player can see Duke's hands and weapons on the screen. The player fights the aliens, most often by shooting at them with different guns, but Duke can also kick, and throw pipe bombs like grenades. The player must also sometimes solve puzzles to find the way through the level.
"Duke Nukem 3D" is set "sometime in the early 21st century", starting in a badly worn down Los Angeles. The game moves on to places such as lunar space stations. An alien transgenic species has invaded Earth while Duke has been fighting in space. Duke crash lands back on Earth and finds most humans are gone. Only a few women remain as slaves for the aliens. America has been turned into a wasteland, and pornography has become the only entertainment.
The levels of "Duke Nukem 3D" take the player outdoors and indoors, on the street, inside military bases, deserts, flooded cities, space stations, moon bases and Japanese villas. Levels were designed with many routes so that players can climb through air ducts, back doors and sewers to avoid enemies or find hidden secrets. This makes the levels well suited to multiplayer deathmatchs. The secret items also include (light switches to make it easier to see, water fountains and broken hydrants provide some health points) or simply provide a touch of diversion and strippers who Duke tells jokes to and sometimes they open up their clothes.
The game includes a range of weapons, some of which, even today, are still unique to the "Duke Nukem" series. They range from Duke's foot for kicking, a pistol, a "Chain gun" (similar in design to the Nordenfelt gun), pipe bombs, freeze- and shrink-rays, and laser-trip-mines.
Aside from weapons, Nukem can also find 'medkits' to heal himself whenever the player chooses. Steroids make the player move faster, as well as removing the effects of the shrink-ray. Nightvision goggles allow players to see enemies in the dark. The "HoloDuke" device projects a fake hologram of Duke that can be used to trick enemies. Protective boots allow the player to cross dangerously hot or toxic floors. For underwater scenes, scuba gear (an aqua-lung) can be used to let Duke breathe. One of the favorite items is the jetpack which allows the player to fly up in the sky, often to reach hidden weapons or extra health. Many of the secret items such as the jetpack, the scuba gear and the night vision goggles only last for a short time. Weapons also have a limited number of ammunition.
There are many monsters in the game. Some of these are aliens, others mutated humans (the LAPD has been turned into monster pigs). Similar to many first-person shooter games, Nukem encounters a large number of weaker enemies, and a small number of boss enemies (extremely powerful). Like Duke, these "boss" enemies have a wide range of weapons and equipment (some weaker enemies have jet packs).
In 1996, at the time of the game's release, Internet-based gaming was just beginning and "Duke Nukem 3D" could be played on IPX LAN or modem. "Duke Nukem 3D" players often used the IPX network utility Kali or the Total Entertainment Network (TEN) online service. Kali allowed users to join a chat room to find opponents. The Total Entertainment Network had hundreds of Duke 3D players online at any time, but players had to pay money monthly for it. The game's levels are often used as the battlegrounds for these online players, bur users are able to create their own levels ("maps"). The game also features co-operative play (co-op) which allows players to fight against the aliens instead of each other. In the "Atomic" version, a new game play mode was introduced: Duke Tag, a "capture the flag" style mode.
Ken Silverman's Build engine allowed complicated levels. The game could use slopes in the floors. It also supports upwards and downwards mouse aiming (though aiming up and down distorts the graphics due to not having perspective correction).
