How to Manage and ID Japanese Maple

Japanese maple is one of the most versatile trees for any yard, patio, or garden. Often grown for its unique 7-palmed green or red colored leaf, the maple also has an interesting growth habit, with a fine leaf texture and muscular-looking multiple trunks. Japanese maples have extraordinary fall colors that range from bright yellow through orange and red, and is often striking, even on trees grown in total shade. Specifics Scientific name: Acer palmatum Pronunciation: AY-ser pal-MAY-tum Family: Aceraceae USDA hardiness zones: USDA hardiness zones: 5B through 8 Origin: not native to North America Uses: Bonsai; container or above-ground planter; near a deck or patio; trainable as a standard; specimen Availability: generally available in many areas within its hardiness range Physical Description Height: 15 to 25 feet Spread: 15 to 25 feet Crown uniformity: symmetrical  canopy  with a regular (or smooth)  outline  and individuals have more or less identical crown forms Crown shape: round; vase shape Crown density: moderate Growth rate: slow Texture: medium Foliage Descriptions Leaf arrangement: opposite/subopposite Leaf type: simple Leaf margin: lobed; serrate Leaf shape: star-shaped Leaf venation: palmate Leaf type and persistence: deciduous Leaf blade length: 2 to 4 inches Leaf color: green Fall color: copper; orange; red; yellow Fall characteristic: showy Popular Maple Cultivars There are many cultivars of Japanese maple with a wide variety of leaf shapes and color, growth habits, and sizes. Here are some of the most popular: Atropurpureum - has reddish leaves with only five lobes  Bloodgood - new foliage is bright red, some leaves darkening to a dim green  Burgundy Lace - reddish foliage with cut leaf (sinus nearly down to the petiole)Dissectum - finely dissected leaves in green or red, growing 10 to 12 feet tall  Elegans - leaves with rose-colored margins when they first unfold  Ornatum - leaf is beautifully cut and reddish Trunk and Branch Descriptions Trunk/bark/branches: bark is thin and easily damaged from mechanical impact; droop as the tree grows, and will require pruning for vehicular or pedestrian clearance beneath the canopy; routinely grown with, or trainable to be grown with, multiple trunks; showy trunk; no thorns Pruning requirement: requires pruning to develop a strong structure Breakage: resistant Current year twig color: green; reddish Current year twig thickness: thin Pruning a Maple Most maples, if in good health and free to grow, need very little pruning. Only train for developing a leading (or multiple) shoot(s) which will eventually establish the trees framework. Maples should not be pruned in spring and could bleed profusely. Wait to prune until late summer to early autumn and only on a young tree. A habit should be encouraged in which the branches develop low and grow up at sharp angles. If suckering of green-leaved root stock occurs below the graft line on your red-leafed grafted variety, remove the green sprout immediately. Japanese Maple Culture Light requirements: tree grows best in part shade/part sun but can also handle the shade. Soil tolerances: clay; loam; sand; slightly alkaline; acidic; well-drained Drought tolerance: moderate Aerosol salt tolerance: none Soil salt tolerance: moderate Common Pests Aphids can infest Japanese maples and heavy populations can cause leaf drop or a dripping of honeydew. Scales can be a problem. Neither insect will cause the tree to die. If borers become active, it probably means you have an already sick tree. Keep the tree healthy. Leaf scorch  may become a problem during periods of high temperatures accompanied by wind. Planting Japanese maple in a bit of shade will help. Keep trees well-watered during dry periods. Symptoms of scorch and drought are tan dead areas on foliage. Bottom Line The growing habit of a Japanese maple varies widely depending on cultivar. From globose (round or spherical form) branching to the ground, to upright to vase-shaped, the maple is always a delight to look at. The globose selections look best when they are allowed to branch to the ground. Be sure to clear all turf away from beneath the branches of these low growing types so the lawn mower will not damage the tree. The more upright selections make a nice patio or small shade trees for residential lots. A large selection or compact cultivars make wonderful accents for any landscape. Japanese maple tends to leaf out early, so it may be injured by spring frosts. Protect them from drying winds and direct sun by providing exposure to partial or filtered shade and well-drained, acid soil with plenty of organic matter, particularly in the southern part of its range. Leaves often scorch in hot summer weather in USDA hardiness zones 7b and 8, unless they are in some shade or irrigated during dry weather. More direct sun can be tolerated in the northern part of the range. Be sure drainage is maintained and never allow water to stand around the roots. The tree grows fine on clay soils as long as the ground is sloped so water does not accumulate in the soil. It responds well to several inches of mulch placed beneath the canopy.

Chasing Zero Essay - 1065 Words

Chasing Zero is a documentary which was meant to both educate the viewer on the prevalence of medical harm as well as to enlighten both the public and health care providers on the preventability of these events (Discovery, 2010). The documentary expounded on the fact each year more people die each year from a preventable medical error than die due to breast cancer, motor vehicle accidents or AIDS (Institute of Medicine, 1999). Medical harm can result from adverse drug events, surgical injuries, wrong-site surgery, suicides, restraint-related injuries, falls, burns, pressure ulcers and mistaken patient identities (Institute of Medicine, 1999). Incidences of medical error have been reported in the media for many years. The most startling†¦show more content†¦One of the most critical factors which contribute to the number of preventable cases of healthcare harm is the culture of silence surrounding these cases. The fear of medical providers to report incidences is related to the possibility of punishment and liability due to a medical error (Discovery, 2010). The criminalization of some acts of medical error has resulted in job dismissal, criminal charges and jail time for some healthcare workers. This is despite the fact that the system they are working in helped to create the situation which led to the error in the first place. Human error, due to fatigue and system errors can result in deadly consequences, but by criminalizing the error it effectively shuts down the ability to correct the root problem. Healthcare workers, working at all levels within the medical system, can provide valuable input on how to improve the processes and prevent harm from occurring (Discovery, 2010). Healthcare workers are not the only ones fearful of exposing medical errors. The medical institutes themselves operate behind a wall of silence. The IOM first recommended a national medical error reporting system in 1999 and despite attempts by then President Clinton, the American Medical Association and the American Hospital Association successfully lobbied against it (Dyess, 2009).

With more and more car manufacturers making new Electric Cars, this is obviously the way forward for the future, but there is obviously a very long way to go. THE ADVANTAGES AND DISADVANTAGES OF THE ELECTRIC CAR Electric cars are not only cheaper and greener to run, but in the long term they will help with the problem the world is facing with running out of oil resources. THE DISADVANTAGES: * They are currently expensive to buy with some costing up to $50,000 * Short battery life (some have to recharge after only 100 miles) * The batteries take up a lot of space * lack of charging points in the community, although this is expected to improve in time * Recharging costs (although cheaper than liquid fuel) can put a sttain on your electricity bill * Recharging the battery can take anything from 1 hour and up to 8 hours * Some are considered to be too small Not an ideal family car, but again this is likely to improve over time * Some consider the designs to be â€Å"ugly† A NEW CONCEPT IDEA: A new concept to increase the cars travel compacity is to have two or more batteries installed, where you can switch to another battery when you start running out of charge. Then whilst you are running on a second battery, a dynamo can recharge your dead battery whilst you are driving. The problem with this is that the batteries would have to be made smaller to be able to fit nicely into the car. How to cite Andvantage and Disadvantage of Electrical Cars, Papers

Early Childhood Language Development-Free-Samples for Students

Question: Discuss about the Early Childhood Language Development. Answer: This essay talks about the strong links between childrens language development and cognitive reasons of their success in school achievements and how these are best facilitated within the social learning as stated by (Fielding-Barnsley Hay, 2012), it discuses about the external outside factors that manipulate them and the social sources which helps them achieve success in school and the outside world. It is very important to achieve the ability to talk for a child in their early childhood. Language is a tool that opens up many opportunities in the social world. Language development is very important in order to communicate and express their feelings and experience and needs. The early childhood starts from the childs primary education and therefore early childhood language learning ability is linked to afterward success of reading. Pre-literacy and literacy activity are very useful and can help children in language aptitudes in both primary school and high school. Children who do not listen and often seen that they are suffering with their language (Trawick-Smith, 2013). Its all co related. In order to make sure that the child is learning to speak and adapt the language adequately, the theory says that it is the job of the teachers to make sure that the children are learning properly. The cognitive development happens according to the childs thought process and how he perceives the world in his knowledge. Children who face late or messy language they go through emotional, psychological and social behavioral problems. In early childhood school learning is very important and proper emphasis should be given in language development. Language motivation shoul d start from both home and school, if proper language development does not take place then it leads to child abuse, and often there are students ragging due to their incapability is speech. The quality of communication should be good between child and teacher. The aim of the current study is to understand the accessible educational investigation the early childhood forerunner reading and writing in kindergarten. Even though child has a big role to play in their individual learning experiences and it depends a lot on the social environment around the child (HUNT, 2016). Children who are shy and less expressive, their cognitive development is completely different. Therefore speech development and to initiate that with a child is even more necessary from infant stage. There are many types of learning; language development can also be in a form of play, singing, recitation. In school every child has friends and communication with them also help them develop language skill The social development is very necessary for every child and for that language development is important. All these are co related and therefore and It is very important for the child to learn to think and explore their mind and with respect to that they can speak their mind. To make sure that the child is learning adequately, it is the work of the parents as well as the teacher to help them build their imagination in order to improve their social shyness. Therefore language development and cognitive development both are interlinked and important in the early development of the child (Otto, 2017). References: Fielding-Barnsley, R., Hay, I. (2012).

The Guitar Essay Example For Students

The Guitar Essay THE HISTORY OF THE GUITARThe guitar is a fretted, stringed instrument, and is a member of the lute family. It originated in Persia and reached Spain during the twelth-century, where it?s versatility as both a solo and accompanying instrument were established. The theory of the guitar was discovered in the early centuries. They found that the sound of a bowstring could be enhanced by attaching a resonating chamber -most like a tortiseshell- to the bow. From the bow came essentially three main types of stringed instruments: the Harp family, which was the sound of plucked strings indirectly transmitted to an attached sound box. The second was the Lyre family, which was strings of a fixed pitch are attached to the directly to a sound chamber. And the third was the Lute family, this was were the pitch of strings was altered by pressing them against a neck that is attached directly to a sound chamber. Within the Lute family came two groups. The lutes proper which had rounded backs and the guitar type instruments with their flat backs. Guitar-shaped instruments appear in stone bas-relief sculptures of the hittites in northern Syria and Asia Minor from as far back as 1350 B.C. We will write a custom essay on The Guitar specifically for you for only $16.38 $13.9/page Order now The word guitar also has origins in the middle and far east, deriving from gut, is the Arabic word for four, and tar, the Sanskrit word for string. The earliest European guitars did have four courses of gut strings. A 2course is a pair of strings tuned in unison. These early guitars were distinguished from lutes by body sides that curved inward to form a waist and by four courses of strings. Some but not all early guitars had a flat back, while lutes always had a flat back. In the Middle Ages and the Renaissance the lute was the dominant fretted instrument. The lute with was pear-shaped and had five or more courses of strings was generally regarded as a higher class of instrument. By 1546 the guitar had gained enough popularity to merit the publication of a book of guitar music. By this time guitars had added another course, and modern tuning had come into existence. Chord positions were the same as they are today. The frets of the early guitars were made of gut and tied around the n eck. This made placement of frets very difficult. The early guitars were also much shorter in length than todays guitars. The second most popular instrument during the Middle ages was the cittern. It was more like the modern guitar than any other during that time. It had metal strings, fixed frets, a fingerboard that extended onto the top, a flat back, and a movable bridge with strings anchored by a tailpiece; and it was played with a quill or plectrum(pick). But this modern instrument soon lost its popularity and disappeared by the late 1600?s. Through the 1600?s and 1700?s the guitar design changed very little, although interest increased around luthiers. In the 1770?s the first guitars with six single strings appeared, 3blowing the evolutionary lid off the instrument. Within the next few decades, numerous innovations followed: body waists became narrower and body bouts changed shape, becoming circular in northern Europe and more oval shaped in southern Europe. Inlaid frets of brass or ivory replaced the tied on gut frets and the neck was extended one full octave(12 frets) clear of the body. Metal tuners with machine heads began to replace friction pegs, and strings were anchored by bridge pins, replacing the method of tying strings to the bridge. By the 1820?s most of the fingerboard extended all the way to the soundhole. As rapidly as the guitar changed so did it?s acceptance. By the 1800?s the Lute had all but disappeared. One of the best known makers of this new-style of guitar was Johann Georg Staufer of Vienna. Staufer and another maker Johann Ertel in 1822 designed a fingerboard raised off the top of the guitar, and experimente d with different fret metals, settling on an alloy of brass,copper,silver, and arsenic. The first half of the 19th century was a time of great experimentation for the guitar. And many of the innovations that were credited to 20th century makers were actually tried a century earlier. Some of them included: The peghead with all six tuners on one side and scroll shape at the top, which is now common of the fender guitars was tried in the 1800?s by Staufer. Gibson came out with the raised 4fingerboard in 1922. Actually it was done exactly 100 years earlier by Staufer and Ertel. In 1988 Fender introduced a scalloped fingerboard on one of it?s models. Again this had been done in the first half of the 1800?s. Artist endorsement models like the Les Paul, Stevie Ray Vaughn, and Chet Atkins model?s, which were of huge success had already been thought of and done like the Luigi Legnani model by Staufer in 1820. .uaadadd4023b9986c324d49f4f76a0f5d , .uaadadd4023b9986c324d49f4f76a0f5d .postImageUrl , .uaadadd4023b9986c324d49f4f76a0f5d .centered-text-area { min-height: 80px; position: relative; } .uaadadd4023b9986c324d49f4f76a0f5d , .uaadadd4023b9986c324d49f4f76a0f5d:hover , .uaadadd4023b9986c324d49f4f76a0f5d:visited , .uaadadd4023b9986c324d49f4f76a0f5d:active { border:0!important; } .uaadadd4023b9986c324d49f4f76a0f5d .clearfix:after { content: ""; display: table; clear: both; } .uaadadd4023b9986c324d49f4f76a0f5d { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uaadadd4023b9986c324d49f4f76a0f5d:active , .uaadadd4023b9986c324d49f4f76a0f5d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uaadadd4023b9986c324d49f4f76a0f5d .centered-text-area { width: 100%; position: relative ; } .uaadadd4023b9986c324d49f4f76a0f5d .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uaadadd4023b9986c324d49f4f76a0f5d .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uaadadd4023b9986c324d49f4f76a0f5d .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uaadadd4023b9986c324d49f4f76a0f5d:hover .ctaButton { background-color: #34495E!important; } .uaadadd4023b9986c324d49f4f76a0f5d .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uaadadd4023b9986c324d49f4f76a0f5d .uaadadd4023b9986c324d49f4f76a0f5d-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uaadadd4023b9986c324d49f4f76a0f5d:after { content: ""; display: block; clear: both; } READ: Alexander the Great EssayIn the early 20th century guitars began to develop into what we know today. In 1903 the first Gibson catalog assured that instruments would be made of woods with the most durable, elastic and sonorous qualities such as maple, mahogany, vermilion, and suitable woods. They settled on maple but only the high-end mandolins were made of maple. It wasn?t until the mid-to-late1920?s, when they finally began to make them with maple wood. During the early 1900?s Gibson and a company out of Chicago, the Larson brothers were the only ones whose instruments were built for steel strings. The others were still made for gut. From the 1850?s to the 1920?s , a vari ety of new guitar designs surfaced, some were outlandish and some were ideas whose time would not arrive until decades later like the Gibson carved top guitar and the Larson Brothers steel-stringed flat top which were both turn-of-the-century innovations. The guitar rested on an evolutionary plateau from the 1850?s into the 1920?s, at least in part to the perfection of C.F Martin?s design. This was partly because the guitar was secondary instrument, and was not 5subject to the competition like the banjo or mandolin. The closest the guitar came to challenging them was in Hawaiian music from 1915 into the 1920?s. But in the 1920?s a demand for greater volume began to revolutionize the banjo and continued to be the strongest driving force for new fretted instrument design for the next three decades. At the same time two new innovations in related fields were changing the musical instrument dramatically. The first advance the phonograph, actually dates back to the late 1800?s, but did not gather full force until after World War I. Recordings made all kinds of music available to people who had no access to any other music except for local and touring bands. The second advance was the radio. From 1920 to 1925 the two were in heated competition, with radio forbidding it?s artists to make records and vice versa. The music industry began and many different styles became popular, such as popular music from Broadway and ?Tin Pan Alley? in New York. Such styles as ?race? or ?blues?, and early jazz later revived as ?Dixieland?, and country music gained footholds in the music marketplace. In the 1920?s t he guitar began to emerge as the common denominator- the most versatile and portable instrument, best able to fill a role in an ensemble or accompany a solo performance. Players with different styles on every type of music appeared, among them Eddie Lang in jazz, Lonnie Johnson in blues and Jimmie Rodgers and Maybelle Carter in country. 6The 1930?s would be the most important decade in the history of the guitar, with more successful innovations than any other period of time. The Impending rise was signaled by the appearance of the first tenor guitars. Just as the tenor banjo, or mandolin-banjo as it was called earlier, owed part of its initial popularity to the ease with which a mandolin player could switch to it. It offered a shortcut for the tenor banjo players to switch to the increasingly popular guitar. Popular music of the 1920?s was becoming louder and louder. The invention of the electronic amplification raised the volume of radios and record players. The little parlor guitar from the previous century just could not cut it in the popular music of the day. In 1928 Andres Segovia first performed in the United Stated, turning the world of classical and semi-classical music on its ear. He brought a practically new style of music. As with many later guitar stars, Segovia had a guitar as influential as the music he played on it. It was made in Spain. in 1850 when C.F Martin was perfecting his x-bracing pattern and developing the American flat top guitar, Antonio de Torres in Spain was perfecting fan bracing and other designs that would characterize the modern classical guitar. The muted resonance of a typical American parlor guitar was no match for the hardy, robust sound of Segovia?s guitar. The new guitar left the American parlor guitar with no protection from the onslaught of new de signs. .u93979fc6c7fabc6cf81fe9f1cd002563 , .u93979fc6c7fabc6cf81fe9f1cd002563 .postImageUrl , .u93979fc6c7fabc6cf81fe9f1cd002563 .centered-text-area { min-height: 80px; position: relative; } .u93979fc6c7fabc6cf81fe9f1cd002563 , .u93979fc6c7fabc6cf81fe9f1cd002563:hover , .u93979fc6c7fabc6cf81fe9f1cd002563:visited , .u93979fc6c7fabc6cf81fe9f1cd002563:active { border:0!important; } .u93979fc6c7fabc6cf81fe9f1cd002563 .clearfix:after { content: ""; display: table; clear: both; } .u93979fc6c7fabc6cf81fe9f1cd002563 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u93979fc6c7fabc6cf81fe9f1cd002563:active , .u93979fc6c7fabc6cf81fe9f1cd002563:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u93979fc6c7fabc6cf81fe9f1cd002563 .centered-text-area { width: 100%; position: relative ; } .u93979fc6c7fabc6cf81fe9f1cd002563 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u93979fc6c7fabc6cf81fe9f1cd002563 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u93979fc6c7fabc6cf81fe9f1cd002563 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u93979fc6c7fabc6cf81fe9f1cd002563:hover .ctaButton { background-color: #34495E!important; } .u93979fc6c7fabc6cf81fe9f1cd002563 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u93979fc6c7fabc6cf81fe9f1cd002563 .u93979fc6c7fabc6cf81fe9f1cd002563-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u93979fc6c7fabc6cf81fe9f1cd002563:after { content: ""; display: block; clear: both; } READ: Drug Abuse Essay7The importance of volume cannot be overstated. The quest for a louder guitar would be the driving force behind all the innovations of the 1920?s and 30?s: the resonator guitars of National and Dobro, Martins dreadnought-sise flat tops, and Gibsons ?advanced? wider archtops and large bodied flat tops. When the limits of the acoustic guitar were reached the quest for volume would spark the invention and evolution of the electric guitar. Although the experimentation on the acoustic guitars continues, the standard acoustic guitars of today were all well developed by the end of the 1930?s. The sign of the electric guitar was in the 1930?s. People such as Les Paul and Eddie Durham were experimenting with the actual products. Durham carved out the inside of an acoustic guitar and put a resonator that he had cut out of a tin pan and placed it inside the guitar. He found that when he struck the strings the sound was greatly increased. By 1932 the Embryonic Rickenbacker company persuaded several of its acquaintance publicize their new lap, steel electric guitar. Eddie Durhams ?Hitting The Bottle? played on this instrument was cited as the first amplified guitar on record. By 1936 he was using a guitar with an electric pickup and had tried converting radio and phonograph amps. That same year the most reputable guitar company, Gibson, would introduce the ES150. Although it was almost identical to the existing L50 acoustic, the presence of an integral bar pickup close to the fingerboard meant this 8guitar was evolutionary. This Gibson model made the electric guitar acceptable. Pickup technology was primitive, Rickenbacker?s pickup was of a horseshoe design, where-by the magnets actually surrounded the strings. Walter Fuller and Gibson combined and designed a more practical pickup using two solid nickel magnets below the strings and a one piece steel bar was surrounded by the pickup coil. This directed the magnetic field toward the strings. After a few years a man by the name of Leo Fender showed up on the scene and improved the electric guitar. His improvements greatly increased its acceptance and popularity with both the musicians and listeners. In 1950 the Fender Company introduced the broadcaster, shortly after to become the telecaster. It pioneered the latest design of bolt on neck and a solid body, electric design. This began a new type of music called Rock and Roll. And so the birth of the electric guitar changed music, but what the people didn?t know is that it would only get better. In 1954,in addition to the telecaster, which was still being produ ced and is still being produced, Fender introduced the most copied body style of the guitar ever. The introduction to the stratocaster brought forth some of the greatest guitarists ever known. It featured the first double cut away, making it easier to reach all of the high strings and also had a third pickup added to it. Then in 1960, one man came along and changed the sound of the guitar forever, Jimmi Hendrix. With his 9explosive riffs and incredible volume he turned the guitar world upsidedown. He began experimenting with ideas to get his guitar to make different sounds and came up with the infamous fuzz face and wah wah pedals which he used to make the guitar almost speak to the audience. Many other legendary guitarists made a name for their selfs with this guitar such as Stevie Ray Vaughn, and Eddie Van Halen, all with similar but greatly different styles of playing. The last major invention of the electric guitar was in 1964 when Rickenbacker introduced the first twelve string electric guitar. From the beginning of its existence to the present day the guitar has taken on more forms and changes than any other instrument to date. Changing in size, shape, material and every other way imaginable. But one thing that hasn?t changed is the impact of a well played guitar riff on ones attitude and emotions. American History

Main Group Elements Definition

Main Group Elements Definition In chemistry and physics, the main group elements are any of the chemical elements belonging to the s and p blocks of the periodic table. The s-block elements are group 1 (alkali metals) and group 2 (alkaline earth metals). The p-block elements are groups 13-18 (basic metals, metalloids, nonmetals, halogens, and noble gases). The s-block elements usually have one oxidation state (1 for group 1 and 2 for group 2). The p-block elements may have more than one oxidation state, but when this happens, the most common oxidation states are separated by two units. Specific examples of main group elements include helium, lithium, boron, carbon, nitrogen, oxygen, fluorine, and neon. Significance of the Main Group Elements The main group elements, along with a few light transition metals, are the most abundant elements in the universe, solar system, and on Earth. For this reason, main group elements are sometimes known as representative elements. Elements That Arent in the Main Group Traditionally, the d-block elements have not been considered to be main group elements. In other words, the transition metals in the middle of the periodic table and the lanthanides and actinides below the main body of the table are not main group elements. Some scientists do not include hydrogen as a main group element. Some scientists believe zinc, cadmium, and mercury should be included as main group elements. Others believe group 3 elements should be added to the group. Arguments may be made for including the lanthanides and actinides, based on their oxidation states. Sources King, R. Bruce (1995).

Planning functions of management - Essay Example However, Nestle usually plans for some period of time. Three to five years are more typical planning horizons. As one of the most important functions of management, planning process is based on stipulated criteria and procedures which have a great impact on planning processes. Criteria such as reduced cost, improved quality, improved sense of direction, better teamwork, and improved service delivery might be used. The timing of any evaluations should also be considered. In Nestle, the plan involves deciding upon how resources will be used to help the organization achieve its strategic goals. It relies more on past records and involves shorter time periods. Present conditions are usually dominant in the planner's mind when the organization initiates a plan and these may be overstressed. Also, many events are obviously unforeseen, but planning can be aided by techniques giving suggested probabilities of events taking place (Bateman, Snell 2004). In Nestle, a special attention is given to product quality and product standards. This policy is important because Nestle produces a wide range of food products from coffee, beverages and ice-cram to infant food and pet food. The responsibility of companies in food industry is to analyze social conditions and possible threats of their products for potential consumers. They should be well aware of regulation changes and should not sell a product which can be injurious to health. In order to meet high standards and quality, Nestle constricts its activities according to legal regulations and requirements stipulated by EU for European countries. Also, planning process include analysis of the macro-environment (e.g., economic trends, inflation, changes in citizen needs, changing demographics, etc.), the government environment (especially changing federalism and state government trends), the competitive environment (the present and potential competition, particularly as related to economic development), the citizen environment (what the service user says), and the organization's internal environment (e.g., is there antiquated technology, high turnover, many people planning to retire soon) (Boone, Kurtz, 1992). Environmental scanning will also identify a variety of factors, both internal and external to Nestle, to be considered as part of the planning process. In fact, one of the benefits of planning is that an organization will gain a better understanding of how environmental scanning should be done and be able to manage more effectively as a result. Factors to be considered as part of the macro-environmental scanning process include social factors such as demographics, financial factors such as interest rates, and political factors such as increasing government deregulation, changing federalism and state government's trends, and regulations (Campbell, 1997). Among the factors to be considered as part of the government environment are the number and locations of other governments, the degree of federal and state government presence, the typical services being provided, and the marketing strategies of other competitive local governments. Ethics and corporate social responsibilities affect all decisions and plans developed and introduced by the company. From the very beginning, Nestle clearly informs customers about threats and possible impact of products. Ethical guidelines and social responsibi
