Avoiding Ice and Snow Damage to Trees

Avoiding Ice and Snow Damage to Trees Brittle tree species that retain dead, persistent winter leaves normally take the brunt of heavy icing after a winter storm. Knowing and managing your brittle trees and you can make it through a normal ice storm. Many of the elms, most true poplars (not yellow poplar), silver maples, birches, willows, and hackberry are tree species that simply cant handle the weight of the ice slurry coating their limbs, persistent leaves, and needles. They do well with the snows of the north but have problems in areas that have regular ice storms. Cold climate conifers like fir, spruce and hemlock can handle moderate icing. Southern yellow pines usually take a beating during major icing events that occur on the edge of their natural range. Brittle trees tend to be fast growers. Because of their desirable growth potential and the prospect of making quick shade, weak trees are sought out and planted by homeowners in late winter ice zones. Planting these trees will only exacerbate the problem of limb breakage during heavy icing. Fast-growing trees often develop weak, V-shaped crotches that easily split apart under the added weight of ice. Because these trees usually take some damage from storms throughout the year, internal rot, decay and included bark (some of which you cannot readily see) lead to weakened trunks and limbs (some callery pears). Multiple leader, upright evergreens, such as arborvitae and juniper, and multiple leader or clump trees, such as birch, are most subject to snow and ice damage. Smaller trees need to be wrapped and larger trees with wide-spreading leaders should be cabled in ice-prone areas. Here are things you can do in the yard or landscape to prevent ice damage: Plant Only Strong Trees in Your Landscape Certain trees are popular year in and year out for a reason - they show well and live well. Prefer these trees but eliminate those I have mentioned that door poorly in ice-prone regions.   Brittle Species Should Not Be Planted These species will not do well on sites where heavy ice and snow is a problem. Brittle species include elm, willow, box-elder, hackberry, true poplar and silver maple. Avoid Planting Species With Persistent Leaves Species  that hold their persistent leaves into late fall and early winter where early ice storms are common isnt a great idea. These trees are quickly damaged and removed where the ice storm is common. Wrap Small Multi-Leader Trees So you have a valuable, small specimen you want to preserve. If ice is predicted, secure the tree with strips of carpet, strong cloth or nylon stockings two-thirds of the way above the weak crotches. Always remove any wrapping during spring to avoid binding new growth and girdling limbs and trunk. Begin an Annual Pruning Program When Trees Are Young There is not much you can do with a weak crotch so use tip 4. Prune dead or weakened limbs and excessive branches from trunk and crowns. This reduces ice weight that can rapidly destroy the trees form. Hire a Professional Arborist The expense is worth it for particularly valuable susceptible or wide-spreading large trees. An arborist can strengthen a tree by installing cabling or bracing on weak limbs and split crotches. Favor Conical Formed Trees Trees like conifers, sweetgum or yellow poplar will be robust additions to your landscape. Species with less branch surface area, such as black walnut, sweetgum, ginkgo, Kentucky coffeetree, white oak, and northern red oak are preferred.

Vectors

Vectors Free Online Research Papers A vector is a mathematical object possessing, and fully described by, a magnitude and a direction. It’s possible to talk about vectors simply in terms of numbers, but it’s often a lot easier to represent them graphically as arrows. The vector’s magnitude is equal to the length of the arrow, and its direction corresponds to where the arrow is pointing. Physicists commonly refer to the point of a vector as its tip and the base as its tail. There are a number of ways to label vectors. You may have seen vectors labeled or A. This book will follow the convention you’ll find on SAT II Physics: vectors are written in boldface and vector magnitudes in plain script. For example, vector A has magnitude A. Vectors vs. Scalars In contrast to a vector quantity, a scalar quantity does not have a direction; it is fully described by just a magnitude. Examples of scalar quantities include the number of words in this sentence and the mass of the Hubble Space Telescope. Vector quantities you’ll likely come across quite frequently in physics include displacement, s; velocity, v; acceleration, a; force, F; momentum, p; electric field, E; and magnetic field, B. When in doubt, ask yourself if a certain quantity comes with a direction. If it does, it’s a vector. If it doesn’t, it’s a scalar.

Economics & Public Policies Essay Example | Topics and Well Written Essays - 2500 words

Economics & Public Policies - Essay Example The paper tells that the production possibilities curve represents the total output of the combination of two products in an economy provided the inputs and technology are available. There are 3 basic assumptions underlying the production possibilities curve: quantity and quality of all resources as inputs fixed; unchanged technology and fully employed resources. If the federal state and local governments in the U.S. engage in increased health-related expenditure, they would require increasing taxes to meet the increased costs. Assuming the fixed quantity of resources, i.e. public taxes and technology over a given time period, the U.S. is capable of providing limited amount of public health care services. This also depends upon how much the taxpayers are willing to sacrifice other goods and services for increased public health service. The production possibilities curve shows that increase in health care services will lead to less of other government public services due to its limite d resources. Therefore, the production of other goods and services will be less. As the quantity of health care services is reduced, the government will be able to provide more of other goods and services. The probable production possibilities curve is provided in the study. When each member of the community makes a voluntary contribution towards per unit of a pure public good, that contribution equals to his/her marginal benefit derived from the public good at efficient level of output. This equilibrium contribution per unit is known as Lindahl price. The Lindahl prices are assigned in such a manner that no budget deficit or surplus arise at the efficient output of the good. Lindahl equilibrium requires that the total contribution by the community towards the public good is equal to the Marginal Social Benefit and total cost of producing that public good (Hyman, 2010, p.165). This means that ?Ti*Q = MC*Q = AC*Q Where Ti is the voluntary contribution by each individual; Q is the eff icient output; MC is the Marginal Cost of pure public good; AC is the Average Cost of pure public good; Therefore, the total contribution or revenue collected will be (?Ti*Q) and it should be equal to the total cost of the production, i.e. AC*Q. MC*Q equal to AC*Q implies there is no budget surplus or deficit. However, assuming that marginal cost of pure public good increases if more is purchased by the community, i.e. MC>AC then ?MBi>AC because MC = ?MBi. Therefore, the sum of per unit voluntary contribution becomes more than the average costs of production and so this will result in budget surplus at the efficient annual output. Answer 3: Pollution Abatement There are very few human activities that do not pollute the environment, and it has become imperative to address the global concerns over the environmental degradation. The objective of a hundred percent pollution abatement cannot be achieved because the regulators do not have the information of the pollution’s marginal external costs and marginal costs of abatement (Grafton, 2004, p.63). Therefore, most of the pollution abatement policies aim to ensure that the pollution control methods are cost-effective. The costs of pollution abatement not only consider the marginal social costs, but also the opportunity costs associated with cleaner environment.

Change and Continuity in Contemporary Business Essay - 1

Change and Continuity in Contemporary Business - Essay Example A smart enterprise would keep a close eye on the changes in competitive advantages of the organization and realign their strategies & policies such that the business revenues and market share can be sustained. Such enterprises grow globally by carefully choosing their countries/regions of expansion after analysis of the external & internal factors that can drive the competitive advantages of the company in those geographies. Ford Motors is one such smart enterprise that has been changing their strategies & policies to sustain the challenges posed by the local factors in a country by not only globalizing rapidly but also changing their strategies pertaining to their regions of operations. This report presents the internal and external factors and the corresponding responses by Ford Motors to sustain as well as grow their business globally. Balanced Score Card System developed by Kaplan and Norton via their book "Balanced Score-Card - Translating Strategy into Action" published in 1996 (Source: http://www.balancedscorecard.org/BSCResources/AbouttheBalancedScorecard/tabid/55/Default.aspx) Ford Motors was incorporated by Henry Ford in 1903 in Dearborn, Michigan, USA. Henry Ford is known to have adapted practices that were not popular in those days - like, doubling per day wages and reducing the shifts from 9 hours to 8 hours. It was the worker friendly policies that boosted productivity of Ford much ahead of their competition. Ford is known for their methods of large scale car manufacturing and management of huge workforces globally. In 1911, Henry Ford established the first production unit outside USA in the UK by converting a tram works at Trafford Park that is in south of Manchester. In 1920, after the Second World War, the famous Dagenham facility was established that formed the base for launch of Ford Motor Company Limited (UK) in 1929 that was the hub of the European Ford organization (till the time Ford Motor Company Europe was established much later in 1967). In 1971 Ford combined the US, Canadian and Mexican operations together and established the North Ameri can Automotive Operations. The Dagenham facility was one of the most productive in assembly plant in entire Europe which, however, was closed in 2001 amidst some local factors that reduced the economy advantages of Ford manufacturing in Britain while the manufacturing in Germany and other parts of Europe was much more economical. The primary reasons for Ford manufacturing closure in Dagenham was the insurgence of shop-floor militants that developed a powerbase disrupting production by launching almost continuous Guerrilla warfare while Germany offered much more peaceful and strike free industrialization proposition. Moreover, Ford Motor Company

Bilingual Education Essay Example | Topics and Well Written Essays - 2500 words

Bilingual Education - Essay Example In his autobiography Hunger of Memory, Rodriquez unintentionally portrays himself as an exception to his own beliefs. (Rodriquez 12) This book tracks this Mexican American from the time that he was a "schoolchild until he became a literary scholar and nationally acclaimed memoirist. His memoir also describes his gradual alienation from his cultural roots as his assimilation into mainstream culture deprives him of his native tongue and his connection to his past. The book achieves popularity at a time when multiculturalism is becoming a force in American education." (Burt 2004) In order to make sense of the factors that make up Rodriquez's life, he chooses his love for languages to explain how his persona is formed. Rodriquez surmises that it is better to have used English in school rather than to have had a bilingual education. As he struggles to prove this, he represents himself with a paradox of emotions, thoughts, and beliefs. It is his opinion that it was the different uses of languages and his reaction to them that sets him apart. According to Rodriquez, "It is not possible for any child ever to use his family's language in school. " He thinks that "not to understand this, is to misunderstand the public uses of schooling and to trivialize the nature of intimate life and a family's language." (Aria 13) In his writings Rodriquez appears to... In his failure to study these anomalies, Rodriquez does a disservice to himself. When he started school, Rodriquez could only speak "fifty stray English words." (Rodriquez 1) Unlike his brother and sister who attended a Roman Catholic school, Rodriquez went to an all white school with children whose parents were professionals. In his mind, this must have presented a sharp contrast to his own parents who were poor and spoke little English. During this time, he also observed that his brother and sister enjoyed a relationship of togetherness, one that left him feeling alone. His sense of alienation continued to grow as he listened to them " communicating among themselves in Spanish." (Rodriquez 1) Rodriquez has been criticized for cutting himself off from his roots. A better argument would be that the languages barriers that were forced upon him caused this gap. Had he been given a bilingual education this would have been different. Instead of living in language compartments at his home and school, his new English language would have blended into that of his native tongue. As his brother and sister did, Rodriquez would have used both languages interchangeably.If one reads Rodriquez's work closely, they sense his great affection for his family. The feelings of shame that he talks about are more general than personal. Nevertheless, it is easier to attack the character of Rodriquez than to discover the bonds that exists between him and his people in spite of their physical and psychological differences. While addressing the relationship between his brother and sister, it is evident that he has the feeling that he is an only child. Rather than to see how a bilingual education might have made a difference, he chooses to feel

coming of age in samoa Essay -- essays research papers

Coming of Age in Somoa Margaret Mead’s â€Å"Coming of Age in Samoa†, which was actually her doctoral dissertation, was compiled in a period of six months starting in 1925. Through it, people were given a look at a society not affected by the problems of 20th century industrial America. She illustrated a picture of a society where love was available for the asking and crime was dealt with by exchanging a few mats. This book helps one to realize the large role played by social environment. One of Mead’s biggest challenges was probably the fact that her fieldwork was done entirely in the Samoan language. In Samoa, few, if any natives spoke English. To get information, Mead spent her time talking to approximately 25 Samoan women. However, she spent much of her focus on two young Samoan women, Fa’apua’a Fa’amu and Fofoa. It is said that one Samoan woman’s life is very much like the next. At the time of her visit to Samoa, Mead, a graduate student was only 23 years old. She was barely older than the girls she interviewed and lovingly called her â€Å"merry companions†. The vision recieved while reading â€Å"Coming of Age in Samoa† is that it is a place of nearly stress free living. The children pass through adolescence without the many pressures put upon teenagers in an industrial America: ...adolescence represented no period of crisis or stress,but was instead an orderly developing of a set of slowly maturing interests and activities (95). According to Mead, families are large, taboos and restrictions are few, and disagreements are settled by the giving of mats. The stresses encountered by American teenagers are unknown to their Samoan counterparts. Mead refers to premarital sex as the â€Å"pastime par excellence† for Samoan youth. She writes that Samoa is a virtual paradise of free love, as the young people from 14 years of age until they are married have nothing on their minds except sex. Of Samoan girls Mead says: She thrusts virtuosity away from her as she thrusts away from her every other sort of responsibility with the invariable comment, â€Å"Laitit a’u† (â€Å"I am but young†). All of her interest is expanded on clandestine sex adventures (33). She explains that growing up can be free, easy and uncomplicated. Romantic love in Samoa is not bound with ideas of monogamy, exclusiveness, jealousy and fidelity as it is in America. Evidently, due to the lack of priva... ...ons. After a girl is eight or nine years old she has learned not to approach a group of older boys. However, when it comes to younger boys, they are taught to antagonize them. The boys are considered â€Å"older† after they have been circumcised. When a girl is looking for her first lover, she looks to an older man, most often a widower or a divorcee. There are two types of sexual relations other than marriage that are recognized by Samoans. These include love affairs between unmarried young people, and also adultery. Although virginity is not expected in girls, Mead claims that it defiantly adds to their attractiveness. Essentially, having sex with a virgin is much more of a feat for a man than sex with a girl who is not. Marriage in Samoa is regarded as a social and economic arrangement in which relative wealth, rank and the skill of both husband and wife must be considered. In conclusion, Margaret Mead’s dissertation on Samoa is still interesting after 75 years. The customs of Samoans, especially those regarding sex are very interesting to people of other cultures. This society rests most of their regard on love and happiness and seem to have been successful in achieving that
