Unlike other types of decay, alpha decay as a process must have a minimum-size atomic nucleus that can support it. Examples of this sort of nuclear transmutation by alpha decay are the decay of uranium to thorium, and that of radium to radon.Īlpha particles are commonly emitted by all of the larger radioactive nuclei such as uranium, thorium, actinium, and radium, as well as the transuranic elements. The atomic number of the atom goes down by two, as a result of the loss of two protons – the atom becomes a new element. When an atom emits an alpha particle in alpha decay, the atom's mass number decreases by four due to the loss of the four nucleons in the alpha particle. The best-known source of alpha particles is alpha decay of heavier (> 106 u atomic weight) atoms. Sources of alpha particles Alpha decay A physicist observes alpha particles from the decay of a polonium source in a cloud chamber Alpha radiation detected in an isopropanol cloud chamber (after injection of an artificial source radon-220). However, helium nuclei produced by particle accelerators ( cyclotrons, synchrotrons, and the like) are less likely to be referred to as "alpha particles". A higher energy version of alphas than produced in alpha decay is a common product of an uncommon nuclear fission result called ternary fission. Thus, alpha particles may be loosely used as a term when referring to stellar helium nuclei reactions (for example the alpha processes), and even when they occur as components of cosmic rays. As with beta and gamma particles/rays, the name used for the particle carries some mild connotations about its production process and energy, but these are not rigorously applied. The nomenclature is not well defined, and thus not all high-velocity helium nuclei are considered by all authors to be alpha particles. ) and alpha particles as interchangeable terms. Some science authors use doubly ionized helium nuclei ( He 2+ To a lesser extent, this is also true of very high-energy helium nuclei produced by particle accelerators. The helium nuclei that form 10–12% of cosmic rays are also usually of much higher energy than those produced by nuclear decay processes, and thus may be highly penetrating and able to traverse the human body and also many metres of dense solid shielding, depending on their energy. However, so-called long range alpha particles from ternary fission are three times as energetic, and penetrate three times as far. (See discussion below for the limits of these figures in alpha decay.) They are a highly ionizing form of particle radiation, and (when resulting from radioactive alpha decay) usually have low penetration depth (stopped by a few centimetres of air, or by the skin). Due to the mechanism of their production in standard alpha radioactive decay, alpha particles generally have a kinetic energy of about 5 MeV, and a velocity in the vicinity of 4% of the speed of light. Once the ion gains electrons from its environment, the alpha particle becomes a normal (electrically neutral) helium atom 4Īlpha particles have a net spin of zero. Indicating a helium ion with a +2 charge (missing its two electrons). Because they are identical to helium nuclei, they are also sometimes written as He 2+ The symbol for the alpha particle is α or α 2+. Alpha particles are named after the first letter in the Greek alphabet, α. They are generally produced in the process of alpha decay, but may also be produced in other ways. Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus.

However, one such dream differs from the others and she sees the vision of a mysterious boy telling her to go into the forest to find a way to save Rosa.Īt some point in her training, Cereza is allowed to try summoning her first Infernal Demon using a special brace provided by Morgana. She always carries her Cheshire doll with her everywhere she goes.ĭuring her time training under Morgana, Cereza frequently experiences a dream that tells her of Avalon Forest, the home of the faeries that she has been strictly warned by her teacher not to venture into at any point. When training to summon her first Infernal Demon, Cereza receives a special brace from Morgana that she wears on her left hand which amplifies her magic power. She wears brown stockings and a pair of flat shoes that tie in ribbons around her legs. Her attire is a brownish suit with trailing sleeves, adorned with a red bow on her chest and puffy shorts. She wears a pair of black rounded glasses, with a singular red gem dangling off the left lens. Her hair is styled into the shape of cat ears with a singular ribbon woven into one, and ending in a long braid. Despite her lack of ability, her convictions in wanting to become strong enough to free her mother from her captivity allows her to summon the bravery needed become a true Umbra Witch and face the perils of the forest.Ĭereza appears as a young teenage girl. Though not quite as timid as her other younger self, Cereza is still inexperienced in the ways of the dark arts. Vowing to one day become a witch worthy of her mother, she steps off into the moonlight. This chapter of her journey having now reached its end, Cereza looks one last time at the house she trained with Morgana. The relationship Cereza forges during her time in Avalon leave her with unforgettable memories that will undoubtedly help shape her into a confident witch able to pursue her dream of becoming a powerful Umbra with a newfound determination. The two eventually reach an understanding, and afterwards they develop true bonds of friendship. She realises that she appreciates Cheshire, and begins to be able to see things from his perspective. The vision of Rosa is an illusion created by the faeries, but the shock to Cereza is real.Īnd yet, after going their separate ways, Cereza realises that her strength does have limits, and she has come to rely on Cheshire. The last straw is when Cheshire gives a vigorous slash to Cereza's mother, causing her to disappear. Cheshire often irritates Cereza by highlighting her inexperience. Cereza decides to name the demon Cheshire, after the toy it possesses, and the two begin their strange and fateful journey.Īt the onset of their travels, the two realise they can very easily rub each other the wrong way. She decides to believe the boy and heads off to the forest.Īfter being chased by a pack of malevolent Faeries, Cereza attempts to summon a demon, and the medium inadvertently becomes her own stuffed animal. One night, a young boy appears in Cereza's dreams, telling her that deep inside the forbidden Avalon Forest, there sleeps something that could aid Cereza to find the power she seeks. Though a strict teacher, Cereza can feel a certain kindness from Morgana, and eventually has come to trust her like she would trust her mother. Morgana saw vast potential in Cereza despite her youth, and began training her rigorously in the Umbran Arts. Tormented by the ridicule of her clan, Cereza ran off to live with a witch named Morgana, who resides just outside Avalon Forest. Never leaving her side, Cheshire often listens to the stories of the lonely girl. She cherishes the stuffed cat toy her mother gave her, which she named "Cheshire". Becoming strong enough to one day help her became Cereza's one motivation for getting through each day. In time, Cereza began to be tortured by nightmares of how powerless she was to help her mother, who had cared so deeply for Cereza. A beautiful young girl born from a bond between the Lumen Sages of light and the Umbra Witches of darkness.Īs relations between these two clans are strictly forbidden, Cereza's birth resulted in her being labelled an outcast, scorned and mocked by the other Umbra. “We’re really about making fitness fun and affordable for everyone in a non-intimidating environment,” said McCall Gosselin, vice president of public relations and communications for the company. Planet Fitness, which has more than 1,500 locations nationally, keeps it simple when it comes to retaining the January gym-goers. Rebranding gyms as places where all, not just gym rats, are welcome That means promoting themselves as inclusive and nonjudgmental - customers who miss several workouts aren’t scolded when they return - while offering deals, fitness and nutrition guidance, and commitment-free memberships to gym-goers. To retain the new patrons, gyms often combine financial incentives with emotional ones. But a time that so often results in a financial windfall for gyms also sees scores of recruits come and go. And nearly all gyms, including LA Fitness, offer sign-up specials in January.Ī number hire new staff to meet the demands of the new customers. Crunch prides itself on its personalized training for members. Chains like Planet Fitness do this, in part, by charging a $10 monthly fee, while Gold’s Gym offers free membership trial passes. On New Year’s Day, an occasion when most companies are closed, gyms stay open due to the onslaught of new customers who kick off fitness regimens at the start of each new year. In 2017, that number grew to 70.2 million Americans, according to the International Health, Racquet, and Sportsclub Association.Īs the number of Americans joining health clubs grows every year, gyms are striving to make January a month where they can retain newcomers for the long haul. In 2010, roughly 50 million people belonged to a fitness center. Instead, they get fit when they’re personally motivated to do so, which may be why some health clubs report that as many new members join in March as they do in January. For others, an arbitrary calendar date isn’t inspiration enough to get people into a gym regularly. These numbers don’t necessarily mean the United States is a nation of quitters, but that it can be challenging to make the time to go to the gym, to know what to do once you get there, and to maintain the practice. Once October rolls around, just 22 percent of the members who joined a gym at the start of the year remain active, according to the data intelligence firm Cardlytics. But many new gym patrons cancel their membership before spring comes, and almost half don’t make it beyond the first month.īy some estimates, more than 12 percent of Americans join gyms in January, higher than the 8 percent on average who join during the rest of the year. Fitness chains across the country profit from this trend annually, signing up droves of people who’ve decided to begin the year by getting into shape. Each year, losing weight and exercising more are among the top goals on new year’s resolution lists.

The Smithy Gang spreads out across the world, their goal really just seeming to be general domination and making the world one filled with weapons, but in their conquest they managed to destroy the Star Road as well, Star Road being a magical place where the wishes of the world are granted. Exor is just one member of a new group of villains known as the Smithy Gang, each major member some sort of living weapon. He gets there surprisingly quickly and with little issue this time around, and after soundly defeating the Koopa King, the princess is saved, the hero is victorious, and a giant sword named Exor plunges down from the sky and scatters all three of those characters across the land. The monstrous turtle Bowser has once again snatched up Princess Toadstool, so Mario heads off to Bowser’s castle to get her back. The stage was set for an ambitious company crossover, and perhaps unsurprisingly, Mario slipped into this new genre as cleanly as he does most every other he’s dipped his toe in, Super Mario RPG: Legend of the Seven Stars providing plenty from both sides of its DNA to enjoy.ĭespite Mario exploring virgin territory in his first RPG, the opening of the game seems all too familiar. A long story, plenty of reading, stat numbers to consider, and a huge variety of enemies would all be required to make this excursion a full-fledged RPG, but Nintendo had perhaps the perfect partner for this venture: Square, the creators of the monumental Final Fantasy series. Mario and Super Mario Kart, one of the first new genres he stuck his mustachioed nose into was a huge departure from the simplicity of jumping over Goombas to get to the right side of a stage. At a time when he was only just getting started spreading his brand to spin-offs like Dr. Back before Paper Mario, back before Mario & Luigi, the portly platforming plumber known as Mario took his first foray into the world of role-playing games with Super Mario RPG: Legend of the Seven Stars.
