Autism Is A Pervasive Developmental Disorder - 1796 Words

Autism is a pervasive developmental disorder that is characterized by a person’s difficulty to communicate. This is due to neurological or biological dysfunction, and is usually diagnosed during early childhood. Autism Spectrum Disorder is more prevalent in boys than in girls. These children can present symptoms of limited or no speech development; they only use direct communication for immediate needs such as water, bathroom or sleep. Until today, there is no cure for ASD, but there are many types of treatment and interventions, such as Speech Therapy, Occupational Therapy and Behavior Therapy. Researchers today have conducted new studies to revise how ASD can be diagnosed and treated. As I said before, the disorder is commonly†¦show more content†¦ASD has become the second most common childhood developmental disorder that affects brain functioning, social-interaction difficulties, communication challenges and a compromise in repetitive behaviors (Autism Speaks, 2013; Neely et al., 2012). Symptoms of autism spectrum disorder vary in children, some show mild symptoms and some show more severe symptoms. These symptoms include communication deficits such as not being able to understand verbal and nonverbal communication such as interpreting gestures and facial expressions. One example can be a smile because it can have a small meaning for a child diagnosed with autism (Autism Speaks, 2013). Children without autism tend to start speaking earlier than children with autism. In comparison to children with the same age, the autistic has less language and communication skil ls (Autism Speaks). The â€Å"Autism Spectrum Disorder† is a term referring to five disorders described under the category of persuasive developmental disorders (PPDs). The first one is the autistic disorder, which is a disorder when the child has a delay in speaking, doesn’t interact with other children and has repetitive behaviors and interests. Autistic disorder should be diagnosed at young age and is also more prevalent in boys, but girls having it display greater severity of symptoms. The Rett’s disorder only occurs in females. This disorder is characterized by normal development up to 5 months of age and followed by an observable decrease in

Unsolved Mysteries †Physics Free Essays

Unsolved Mysteries – Beyond the standard model The Standard Model is nowhere near perfect. It may explain the six quarks, leptons, and four forces, but it is not complete. There are still questions about antimatter, dark matter, and the inability for the Standard Model to predict particle mass. We will write a custom essay sample on Unsolved Mysteries – Physics or any similar topic only for you Order Now There is no guarantee that quarks and leptons are actually fundamental. Lastly, scientists still don’t understand gravity’s role. Unsolved Mysteries – The standard model as a theory The Standard Model is not wrong. However, it needs to be added to as it is an incomplete theory. https://donemyessay.com/physics/ If the Standard Model can be expanded to understand mass, gravity, and other important pieces of information. Unsolved Mysteries – Three Generations There are three different sets of quark and lepton pairs, and these sets are called generations. Scientists do not know why there are only three generations, or why they exist in the first place. For example, up/down are first generation quarks, and the electron and its neutrino are the first generation leptons. Unsolved Mysteries – What about masses? The Standard Model also has another major flaw, as it cannot explain why a article has a certain mass. Scientists believe it is linked to something called the Higgs field, and are looking for a Higgs boson. However, these theories are still unconfirmed. Unsolved Mysteries – Grand Unified Theory Scientists have a major goal of creating a theory which will combine all of the fundamental forces into one, which would allow them to understand the universe. It would also give scientists more answers and make study possibly easier. James Maxwell was successful at unifying electricity and magnetism. Unsolved Mysteries – Forces and the Grand Unified Theory There is a belief currently swinging around that forces may merge at high energies. This means that all interactions we observe are all different aspects of the same, unified interaction. This does not make complete sense to scientists, which makes everything confusing. The Grand Unifying Theory also implies that there is a force-carrier particle to cause protons to decay. Unsolved Mysteries – Supersymmetry Another interesting idea is the existence of â€Å"squarks†. These supersymmetric shadow particles need to exist, apparently, for gravity to make sense and be able to e combined with other fundamental theories. Scientists do not know if they actually exist yet. Unsolved Mysteries – String theory The fact that we live in three dimensions means that quantum mechanics, relativity, and gravity do not actually go together too well. There is a belief that particles are strings and membranes which are also involved with very small dimensions. All of this is confusing. Unsolved Mysteries – Extra Dimensions The idea of extra dimensions comes from the fact that, as humans, we cannot see everything. To a smaller creature, these extra dimensions may be more visible. A preterred example is a tlea and a human on a tightrope. although the human can only go one way, the flea has more options. This technically creates another dimension that only the flea can use. Unsolved Mysteries – Dark matter Lastly, there is also the idea that the Earth is not made up of the same material as a majority of the universe. There is invisible dark matter which is involved with gravitational effects. There is also evidence that it is not made up of protons, neutrons, or electrons, but perhaps one of the supersymmetric particles, or something that has yet to be discovered.

Diego Velazquez Example For Students

Diego Velazquez Biography Biography Diego Rodriguez de Silva y Velà ¡zquez  (1599–1660) Spanish painter of Portuguese descent, born in Seville. At the age of 14 he began to study under Francisco Pacheco, an indifferent artist whose daughter he married. At first working closely from life, he painted genre scenes, such as kitchen interiors, with figures and objects in realistic detail. The strong contrasts of light and shade recall the chiaroscuro of Caravaggio, then becoming popular in Spain. In 1622 and 1623 Velà ¡zquez visited Madrid where he painted his first portrait of Philip IV, which led to his appointment as court painter and to other more or less honorific appointments as his reputation grew. Rubens visited Madrid in 1628 and his influence enabled Velà ¡zquez to go on a two-year visit to Italy (1629–31), which resulted in a softening of the harshness of his early style: colour began to show in the shadows, light and space became his preoccupations, whilst the range of subjects was enlarged. He resumed his position as royal painter on his return. In his royal portraits he avoids flattery but the infantes and infantas have freshness and charm despite their elaborate and formal clothes. Velà ¡zquez was an assiduous courtier, eager for royal favours but his treatment of his masters is unsparing. In his only surviving battle piece, the Surrender of Breda (1634–35), the chivalrous compassion depicted in the attitude of the victors to the defeated gives a humanity to the picture almost unknown in paintings of this kind. Where he is less inhibited by his subject, e.g. in his pictures of court jesters and buffoons (notably the moving Calabazas, 1637, in the Prado), he is at his most effective in combining realism with interpretation of character. The loose brush work of the views of the Medici Gardens, two of his rare landscapes, indicate a stylistic development to which his second visit to Italy (1648–51) may have contributed. To this last period belong the masterpieces The Toilet of Venus (The Rokeby Venus, painted in Italy, his only nude, now in the National Gallery, London), the outstanding portraits of his mulatto slave Juan de Pareja (1649, New York), Pope Innocent X (1650, the subject said ‘troppo vero’), Maids of Honour (Las Meninas, 1656, in the Prado, Madrid), voted in 1985 as ‘the world’s greatest painting’ by an international panel of experts and The Tapestry Weavers (Las Hilanderas). Velà ¡zquez was a rapid but not very prolific painter: of 125 canvasses confidently attributed only 98 survive. He founded no school of painting and his genius was unknown outside Spain until the 19th century. Among painters deeply influenced by Velà ¡zquez were Manet, Picasso, Dalà ­ and Bacon.
