Undulator
Undulators can provide hundreds of time more magnetic flux than a simple bending magnet and as such are in high demand at synchrotron radiation facilities.  For an undulator that repeat N times (N periods), the brightness can be up to  more than a bending magnet.  The intensity is enhanced up to a factor of N at harmonic wavelengths due to the constructive interference of the fields emitted during the N radiation periods.  The usual pulse is a sine wave with some envelope.  The second factor of N comes from the reduction of the emission angle associated with these harmonics, which is reduced in proportion to 1/N.  When the electrons come with half the period, they interfere destructively. So, the undulator stays dark. The same is true if the electrons come as a bead chain.  Because the bunch of electron spreads out the more times that they travel around the synchrotron, physicists want to design new machines that throw out the electron bunches before they have a chance to spread out.  This change will produced more useful synchrotron radiation.

Sea urchin
The first echinoid fossils are from the Lower Ordovician period. The earliest forms had flexible tests, with plates that could slide over each other. Echinoids were a relatively unimportant part of the biota in the Palaeozoic. Only one group survived the P/Tr extinction event to form the basis of all later echinoids. The group which survived into the Triassic, the Cidaroids, radiated into all other modern groups, which are known as the Euechinoids.
Ospedale degli Incurabili
The hospital was built by Gaetano da Thiene. At first it was a hospital for sick people who can not be cured. Later, it became an orphanage. A church was built on the hospital's courtyard in 1565. The church was closed in 1831. It was later destroyed.

Ned Kelly
But the plan to derail the police train failed. The police protecting Aaron Sherritt were too scared to leave his hut and the murder was not reported until the next day. The Kellys had to wait 24 hours longer for the police train than they had planned. The hostages were becoming difficult to control. To keep them amused the outlaws held a dance in the hotel, where Kelly danced a quadrille with Jane Jones, daughter of the hotel owner. They also had sporting events including the hop, step and jump. Kelly used two revolvers as extra weights while taking part in the jumping.  A local school teacher, Thomas Curnow, talked Ned into letting him take his family home. As soon as he was free Curnow went down to the railway line, waving a lantern (light) wrapped in his red scarf. The train stopped safely.

Like most steak cuts, picanha can be cooked with different methods. It could be cooked on a skewer like in some Brazilian steakhouses or churrascarias.
Four-wheel drive
Part-time All-wheel drive (AWD) operate as a front-wheel drive under normal conditions. When traction is lost for any reason, the system automatically sends a portion of the engine's power to the rear wheels. As soon as the system detects good traction, it disengages the rear wheels and shifts back to front drive. This is a less expensive system that adds less weight to the vehicle (usually a car). This makes it popular on compact vehicles. It typically gets better fuel economy than all-wheel drive vehicles. They do not have a low range or a transfer case.
Steve Bing
Bing committed suicide on June 22, 2020 by jumping off his apartment building in Los Angeles, aged 55.
Voltage
Voltage is always measured between two points, and one of them is often called the "ground", or the zero volt (0V) point. In most AC electrical installations there is a connection to the earth. A connection is made to the real ground through a water pipe, a ground rod buried or driven into the earth, or a convenient metallic conductor (not a gas pipe) buried underground.  This connection is made at the point of entry of the electric system into a building, at every pole where there is a transformer at the street (often on an electric pole), and other places in the system. The whole planet Earth is used as a reference point for measuring voltage. In a building this ground is carried to each electrical device on two wires. One is the 'grounding conductor' (the green or bare wire) and is used as a safety ground to connect metal parts of equipment to the earth.  The other is used as one of the electric conductors in the circuits of the system and is called the 'neutral conductor'. This wire which is at the ground potential completes all the circuits by carrying the current from any electric equipment back to the systems entry point into the buildings and then to the transformer usually at the street.  In many places outside the buildings it becomes unnecessary to have a wire to complete the circuits and carry the current from the buildings to the generators.  The return path that carries all the current back is the earth itself.

Thallium
It is used in rat poisons and insecticides. The use of thallium as a poison has been reduced or banned in many countries because these countries think that thallium might cause cancers. It is also used in infrared detectors. It has been used in some murders. Like arsenic, the use of thallium in murders has given it the name "inheritance powder". Thallium compounds are used in glass for infrared light. Thallium was also used to kill skin infections, but it is too toxic to be used for that now. A superconductor that can work at higher temperatures than normal ones do uses thallium. A radioactive thallium isotope was used for nuclear scans. An alloy of thallium and mercury has a low freezing temperature and is a liquid. A very dense solution of a thallium compound was used to test minerals for specific gravity, but it is too toxic for use.
Phil O'Donnell
Former Scottish First Minister Jack McConnell, MSP for Motherwell and Wishaw, was among those to pay tribute. He hailed the midfielder as a "great professional." He said, "as captain he helped transform Motherwell this season. Phil will be sadly missed by his family and by football fans but he will be mourned by the whole community."
Berlin Wall
Many people even climbed up onto the wall by the Brandenburg Gate in protest and began to chisel away at the wall. The GDR authorities responded to this initially by blasting the people with water cannons; this proved to be ineffective. The East German army later climbed up onto the wall to prevent others from standing on the wall. The government began demolishing the wall the next day. The fall of the wall destroyed the SED, the ruling party of the GDR, and caused many of its officials to resign. The German Democratic Republic would cease to exist less than a year later; reuniting with the Federal Republic of Germany on October 3, 1990.

After befriending a horse named Altivo, they land off the Mexican coast. After seeing landmarks on the map, they take a direction to the legendary golden city. As they arrive at the waterfall, a woman and an army of guards recognize them as gods, and escort them to the city. There, they meet the elders, kindhearted Chief Tannabok and the malicious high priest Tzekel Kan.

Gamophobia
Rather than a phobia, such behavior is linked to a number of personality disorders and neuroses. The majority of phobias are socially created, and are not found in any DSM Psychology manual. The inability to allow oneself to  be vulnerable and show their 'bad parts' has a personality disorder. When the individual displays reaction formation (love to hate) this is a neurotic defense mechanism. This can also be known as commitment phobia.
