An example of apex predators affecting an ecosystem is in Yellowstone National Park. After the gray wolf was reintroduced, in 1995, researchers noticed big changes occurring in the Greater Yellowstone Ecosystem. Elk, the primary prey of the gray wolf, became less abundant and changed their behavior. This freed the riparian (river) zones from constant grazing. This allowed willows, aspens, and cottonwoods to grow, so creating a habitat for beaver, moose, and scores of other species. In addition to the effects on prey species, the gray wolf's presence also affected the park's grizzly bear, a vulnerable species. The bears, emerging from hibernation, chose to scavenge off wolf kills after fasting for months. They can also eat wolf kills in autumn to prepare for hibernation. As grizzly bears give birth during hibernation, a greater food supply may improve the mother’s nutrition and increase the number of cubs. Dozens of other species, including eagles, ravens, magpies, coyotes, and black bears, have been seen scavenging from wolf kills.
Federico Bahamontes
Federico Martín Bahamontes (born 9 July 1928) is a Spanish retired professional cyclist. He was the first cyclist to win the "King of the Mountains" competition for best climber in all three Grand Tours, the Tour de France, the Giro d'Italia and the Vuelta a España.
Bahamontes was born in Santo Domingo-Caudilla, Toledo.
Bahamontes was a climbing specialist. He won the Tour de France in 1959, and won the polka dot jersey for the best climber six times, in 1954, 1958, 1959, 1962, 1963 and 1964. In total, he won seven Tour stages. Reporters gave him the nickname the 'Eagle of Toledo'.
He was second in the 1957 Vuelta a España and won the mountains competition in 1957 and 1958. He won the mountains competition in the Giro d'Italia in 1956.
Bahamontes retired in 1965 to run a bicycle and motorcycle shop in Toledo.
In 2013 he was named the best climber in the history of the Tour de France by L' Équipe Magazine. Members of the jury included current riders, such as Thomas Voeckler, five-times winner of the race Bernard Hinault and the general director of the Tour de France Christian Prudhomme. The award was given by the French President François Hollande.
He is mentioned in the French film "Le Fabuleux Déstin d'Amélie Poulain", known in English as Amelie. Amélie finds a box of toys left behind by an owner of her flat. She returns them to the owner and he is reminded of watching Bahamontes win the 1959 Tour de France.

During construction, the bridge collapsed on 31 August 1939. This led to 18 construction workers being killed. Construction was completed in 1943.
Enthalpy of vaporization
The Enthalpy of vaporization, also called the latent heat of vaporization is the change in the enthalpy needed to change an amount of liquid into a gas. It happens at a given pressure. The enthalpies of vaporization are usually measured at the normal boiling point for that substance. The units are usually J/mol.
An example is when the cooling effects of vaporization controls the body temperature of humans. Warm weather or exercise creates heat in the body. This causes the body to sweat (or perspire). The body feels cooler when the liquid sweat evaporates. As the humidity increases, the rate of evaporation decreases. This determines the body's comfort level.

SIM card
A SIM card is a smart card that is used in mobile phones, to identify the client. SIM stands for subscriber identity module. A SIM card has a microchip, and its use is protected by a PIN. When the phone is powered on, an international mobile subscriber identity number (IMSI) is broadcast. The microchip is also needed for some encryption and decryption. The SIM card and the device that it is used in (the mobile phone) are often referred to as the "Mobile station".
SIM cards come in different sizes. Full-size SIM cards, which are about the same size as a credit card, are not used in phones anymore. Most smartphones use either micro SIM or nano SIM cards, but older ones use mini SIM.

Counting coup
Counting coup refers to the winning of prestige in battle by the Plains Indians of North America. Warriors won prestige by acts of courage in the face of the enemy. Any blow struck against the enemy counted as a coup.
Counting coup could be with a hand, any part of the body, or with an object. The most prestigious act was to touch or strike an enemy warrior, leave him alive, then escaping unharmed. Touching the first enemy to die in battle or touching the enemy's defensive works also counted as coup. Counting coup could also involve stealing an enemy's weapons or horses tied up to his lodge in camp. Risk of injury or death was required to count coup. After a battle or exploit, the people of a tribe would gather together to recount their acts of bravery and "count coup." Coups were recorded in some tribes by putting notches (cut marks) in a coup stick. A coup stick was often a willow rod with a feather on the end. But coup could be counted with any object.
Another form of counting coup emerged during the air battles of World War I. A allied pilot who shot down five enemy aircraft was given the status of ace. The exception was that the British never formally adopted the ace system. Informally, however, a British pilot who had shot down ten enemy planes was considered an ace. Generally "counting coup" is counting victories.
