Energy Efficient Building Design Strategies For Hot Climates Construction Essay This research discusses energy efficient design strategies of traditional houses in Iraq (hot-arid climate), climatic design techniques and potentials for renewable energy systems that can be implemented in the contemporary residential design techniques in order to offset the absence of produced energy (due to current economic and political issues) and help decreasing demand for electricity, which is used extensively to overcome the indoor thermal discomfort during the harsh summer seasons. A comparison between traditional Baghdadi house (Hosh), which existed before the discovery of oil, and a contemporary house design option is to be made to evaluate the thermal performance of both options in this climatic zone in order to adapt more energy efficient design strategies; and also to integrate features for sustainable building design and potentials to implement renewable energy systems. A simulation modeling is to be used to conduct analysis of energy efficient design strategies, namely relating to building envelope, size and direction, ventilation, shading elements, and using renewable energy systems in order to present recommendations that helps in consequential energy offset while preserving comfort. Keywords: Introduction Examining the energy demand in such region, buildings, with particular reference to residential houses, are one of the most significant energy-sensitive entities (Al-ajmi Hanby, 2008). It is stated that buildings consume over half of all electricity and one-third of natural gas (Yilmaz, 2007). Reduction of energy consumption in residential buildings is a major aim worldwide and is a particular challenge in this region for the reasons mentioned previously (Al-ajmi Hanby, 2008). Therefore, sustainable design strategies are of great importance nowadays in order to reduce energy consumption in residential buildings. One may say that sustainability was already a driving force in the past, showing its validity in those days in different forms and techniques. Therefore, problems and precautions in design and construction did not change fundamentally, although a lot of development was seen in materials and technology. Of course, these developments may have had some negative effects (Yilmaz, 2007). Energy efficient design strategies for traditional houses in such climate are significantly different from each other as it can be easily seen in the traditional design (Yilmaz, 2007). Description of Problem Area Energy consumption is becoming more and more important in todays world because of a possible energy shortage in the future. Efficient use of energy has become a key issue for the most energy policies (Yilmaz, 2007). In regions where hot-arid climatic zone is prevailed, practically in Iraq, present economic and political circumstances have become the main reasons that led to a significant energy shortage although Iraq has a spare operational capacity of oil supply in comparison with other countries around the world. A significant need for new energy efficient design strategies and developed buildings construction standards in this area has become essential in order to offset the absence of produced energy and help decreasing demand for electricity, much of which is consumed in air conditioning systems, which is used extensively to overcome the indoor thermal discomfort during the harsh summer seasons (Al-ajmi Hanby, 2008). Conceptual Framework Figure (1) provides a diagram of the conceptual framework that has devised for this research. The proposed research study into traditional and contemporary building design systems will rely on an experimental research strategy in the positivist system of inquiry (developed design strategies). The research will attempt to establish a comparison (Groat and Wang, 2002, P. 254) between a treatment (independent variable) and an outcome (dependent variable) through the evaluation of measured results. Figure (1) Conceptual diagram of the research variables (Groat Wang, 2002) Research Questions Do traditional houses perform better than contemporary ones? Why? Is it feasible to use traditional design strategies in contemporary houses? How could we achieve a sustainable building design in such climatic zone? Do we need new or developed strategies in order to achieve sustainable building design in such climatic region? What if we integrate renewable energy systems into traditional house design? Project Goals and Specific Objectives The purpose of this research is to: Make a comparison and evaluation of thermal performance of residential houses (traditional vs. contemporary) in Iraq (hot-arid climate) in order to adapt more developed and energy efficient design strategies. Integrate new trends for sustainable design in residential houses in this area. Potentials to implement renewable energy systems. This research is achieved through the following: Extensive overview of the antecedent literature in the area of energy efficiency and thermal building performance in such climatic zone. Identify the most effective strategy from the literature that can be applied in order to develop more energy efficient design strategies. Un-wrap issues of energy efficiency, building performance and sustainable design systems. Use a simulation modeling as a tactical tool to make comparison between contemporary and traditional building design systems and energy performance in order to investigate the thermal characteristics and energy savings for both building designs using different strategies and also potentials to integrate sustainable features using renewable energy system. Test outcome results and write a research report accordingly which combines my understanding of the relevant theory and previous research with the results of my empirical research. Literature Review The literature review is structured around the key concepts of significance of energy efficient design strategies, thermodynamics of hot-arid climates, Inventory of traditional design elements in hot-arid climate and energy simulation methods. These key concepts have led to the research questions and the proposed methodology for this research proposal. See figure1 for the map of literature reviewed. Figure () Map of sources reviewed Figure () Research Literature Review Diagrammatic (Groat Wang, 2002) Building Design Strategies Climatic Building Strategies Research by Ochoa Capeluto (2008) states a quick review of design strategies for different climatic zones. This is necessary to examine when and how design strategies should be considered, particularly during design process. Climatic building strategies in hot climates differ from those of cold ones, For example, in cold climates heat collection and storage is essential, and ventilation must be limited for the same reasons. Short daytime and low radiation levels in winter make maximum penetration of natural light to be desired. On the other hand, in hot climates heat must be excluded, the amount of relative humidity controlled, and the thermal mass cooled usually through natural ventilation during the night. Daylight penetration must be carefully managed using control devices (see figure 1) (as cited in Ochoa Capeluto, 2008, Building and Environment, P.1830). Figure (1) Building strategies for cold and hot climates (Ochoa Capeluto, 2008). Optimized Building Envelope A building envelope is a skin that separates between the interior and the exterior of a building. It serves as the outer shell to protect the indoor environment as well as to facilitate its climate control (controlling heat transfer between building layers). The study by Danny Harvey (2009) reviews the literature concerning energy efficiency that can be achieved through optimized building envelope. According to Danny Harvey (2009), The effectiveness of the thermal envelope depends on: (1) The insulation levels in the walls, ceiling, and other building parts; (2) The thermal properties of windows and doors; and (3) The rate of uncontrolled exchange of inside and outside air which, in turn, depends in part on the air tightness of the envelope (infiltration/excitation) (Energy Efficiency, P. 141). Reducing the Cooling Load Energy conservation and climatic design techniques that can be implemented in residential houses in this area (hot-arid climate) are useful for reducing cooling energy consumption (Al-Temeemi, 1995). Danny Harveys (2009) research found the following: Reducing the cooling load requires: (1) Orienting a building to minimize the wall area facing directions that are most difficult to shade from the sun; (2) Clustering buildings to provide some degree of self shading (as in many traditional communities in hot climates); (3) Providing fixed or adjustable shading; (4) Using highly reflective building materials; (5) Increasing insulation; (6) Using windows that transmit a relatively small fraction (as little at 25%) of the total (visible + invisible) incident solar energy while permitting a larger fraction of the visible radiation to enter for daylighting purposes; (7) Utilizing thermal mass to minimize daytime interior temperature peaks; (8) Utilizing night time ventilation to remove daytime heat; and (9) Minimizing internal heat gains by using efficient lighting and appliances. The combination of external insulation, thermal mass, and night ventilation is particularly effective in hot-arid climates, as placing the insulation on the outside exposes the thermal mass to cool night air while minimizing the inward penetration of daytime heat into the thermal mass (Energy Efficiency, P. 141). Passive cooling techniques By using the above measures to reduce the thermal load of the building, other techniques requires small inputs of mechanical energy to optimize passive cooling processes (Danny Harvey, 2009). Danny Harveys (2009) research discussed the following major passive cooling techniques: Passive ventilation Passive ventilation reduces the need for mechanical cooling by directly removing warm air when the incoming air is cooler than the outgoing air, reducing the perceived temperature due to the cooling effect of air motion and increasing the acceptable temperature through psychological adaptation when the occupants have control of operable windows. Passive ventilation requires a driving force, and an adequate number of openings, to produce airflow. It can be induced through pressure differences arising from inside-outside temperature differences or from wind. Design features, especially traditional, that create thermal driving forces and/or utilize wind effects include courtyards, atria, wind towers, solar chimneys, and operable windows. Passive ventilation not only reduces energy use, but can improve air quality and gives people what they generally want. In buildings with good thermal mass exposed to the interior air, passive ventilation can continue right through the night, sometimes more vigorously than during the day due to the greater temperature difference between the internal and external air. Night time ventilation, in turn, serves to reduce the cooling load by making use of cool ambient air to remove heat (as cited in Danny Harvey, 2009, Energy Efficiency, P.142). Evaporative cooling Danny Harveys (2009) study further discussed the following in terms of producing evaporative cooling techniques: Evaporation of water cools the remaining liquid water and air that comes into contact with it. The coldest temperature that can be achieved through evaporation is called the wet-bulb temperature and depends on the initial temperature and humidity (the higher the initial humidity, the less evaporation and cooling that can occur). There are two methods of evaporative cooling the air supplied to buildings. In a direct evaporative cooler, water evaporates directly into the air stream to be cooled. In an indirect evaporative cooler, water evaporates into and cools a secondary air stream, which cools the supply air through a heat exchanger without adding moisture. By appropriately combining direct and indirect systems, evaporative cooling can provide comfortable temperature-humidity combinations most of the time in most parts of the world. Evaporative cooling is most effective in dry regions, but water may be a limiting factor in such regions. However, arid regions tend to have a large diu rnal temperature range, so thermal mass with external insulation and night ventilation can be used instead (Energy Efficiency, P.142). Influence of Energy Efficient Design Strategies on Design Stages The architectural design process is iterative and moves from the abstract (definition of massing, orientation, and image) to the specific (lighting control, mechanical ventilation type) (as cited in Ochoa Capeluto, 2008, Building and Environment, P.1830). At the design stage, key decisions taken by architects can significantly influence potentials to optimize building efficiency. These include decisions affecting the selection of building components. According to Ochoa Capeluto (2008), As it advances and more specialists are called in to solve details, earlier decisions, which could have an enormous influence on the building performance, are expensive and harder if not impossible to change (Building and Environment, P.1830). Other influential factors unrelated to climatic strategies must be taken into account. For example, a certain orientation that is bad for energy consumption might define how well the building performs (Ochoa Capeluto, 2008). However, it would require an Integrated Design Process (IDP), in which the design process optimizes the building performance by involving all members of design-making team from the beginning. The importance of an Integrated Design Process (IDP) on building systems approach Danny Harveys (2009) study found the following: The systems approach requires an Integrated Design Process (IDP), in which the building performance is optimized through an iterative process that involves all members of the design team from the beginning. However, the conventional process of designing a building is a largely linear process, in which the architect makes a number of design decisions with little or no consideration of their energy implications and then passes on the design to the engineers, who are supposed to make the building habitable through mechanical systems (Energy Efficiency, P. 140). The steps in the most basic IDP are: to consider building orientation, form, and thermal mass to specify a high-performance building envelope to maximize passive heating, cooling, ventilation, and daylighting to install efficient systems to meet remaining loads to ensure that individual energy-using devices are as efficient as possible and properly sized to ensure the systems and devices are properly commissioned By focusing on building form and a high-performance envelope, heating, and cooling loads are minimized, daylighting opportunities are maximized, and mechanical systems can be greatly downsized (Danny Harvey, 2009). Thermodynamics of Hot-Arid Climates Any consideration to energy efficiency applications or design strategies in any climatic zone requires examining of thermodynamics and human comfort. In his Text Natural Energy and Vernacular Architecture: Principles and Examples, With Reference to Hot Arid Climates, the author demonstrates properties of energy that must be considered in order to fully understand climatic phenomena. Heat, radiation, pressure, humidity, and wind, among other factors, interact mutually to establish microclimatic conditions appropriate to hot-arid climatic (Fathy, 1986). According to Fathy (1986), the following are some of these basic concepts applied to hot-arid climates: Thermal gain Solar radiation is the principal source of heat in hot-arid zones, and this heat can be transmitted during the day to the building interior in a number of ways. The most important is by conduction of the absorbed solar radiation through the walls or roof at a rate determined by the thermal conductance (or thermal resistivity) of wall components. (The relationship involving the incoming and reflected solar radiation absorbed and re-emitted heat and heat gain is shown in figure 2 below for the case of a typical white painted surface). Figure (2) (Fathy, 1986) Heat gain can also be caused by ventilation. The rate of gain is dependent on the ventilation rate. Ventilation heat gain can be avoided by restricting the size of openings, especially during the heat of the day. The other sources of heat gain are the inhabitants of the building themselves and household equipment such as electric lights and appliances. These sources, unlike the solar radiation, can contribute heat even at night (see figure 3) (Fathy, 1986). Figure (3) Modes of heat transfer (Fathy, 1986) Thermal loss Heat is lost by conduction through the walls, by exactly the same process that it is gained from the direct solar radiation once it has been absorbed by the surface or through the roof by a combination of convection and conduction. Ventilation is also another mode of heat loss. Evaporation from the surface of the building or from objects within the interior can produce a cooling effect on the building which acts as a source of heat loss. In hot arid climates, this can be a particularly effective cooling mechanism since the rate of evaporation in dry air is very high. Figure 3 also shows the modes of heat loss (Fathy, 1986). Cooling by evaporation Evaporative cooling is used for cooling in hot dry areas (such as in Iraq, where the people place against the windows panels of dried desert plants, which are kept moist by water dripping from perforated pipes positioned above them) (Fathy, 1986). Dynamic thermal equilibrium The heat gained by the building can be expected to be balanced by the heat lost and an internal temperature distribution thus established. These temperatures are dependent on the outside temperature and the ratio of the heat gained to the heat lost and can be adjusted by regulating the sources of heat gain and loss. Before examining the systems and devices that have been developed to do this in the hot arid zones, it is first necessary to have an idea of the heat-regulating mechanism of the human body and the microclimatic conditions for human comfort. Table (1) Heat gain and loss processes for the human body (Fathy, 1986). Mechanism Gain Process Loss Process Metabolism Basal heat production Digestion Activity Muscle tensing and shivering in response to cold Radiation From solar radiation-direct and reflected To surrounding air From radiation by radiators Conduction From air above skin temperature (increased by air movement) To air below skin temperature From warmer bodies in contact To cooler bodies in contact Evaporation From respiratory tract From skin covered with perspiration or applied water Conditions of human comfort A convenient standard for thermal comfort is required. Analysis shows that a variety of factors can be involved in situations of discomfort. For example, temperature alone does not determine discomfort. In Athens, 32  °C is quite bearable, but it is generally intolerable in Bahrain. The difference is due entirely to the relative humidity of the atmosphere. In Bahrain the air is very humid and perspiration evaporates slowly, decreasing the bodys ability to lose heat. In Athens, with its dry air, the evaporation rate is high and perspiration evaporates quickly lowering body temperature. The factors that have been identified as standard for thermal comfort within buildings are: air temperature, air humidity, rate of air movement, level of radiation, and rate of heat production by the bodies of people in the building [4]. Inventory of design elements for traditional housing design in hot-arid climates Building materials The materials surrounding the occupants of a building are of prime importance for protection against heat and cold. Considering an external wall exposed to a high outside air temperature and a lower inside air temperature (see figure 4), the rate of heat flow transmitted through the wall from the outside air to the inside air is proportional to the air temperature difference, area of the wall, and rate of global heat transmittance that can be determined from an analysis of the components of the total resistance to heat flow. The total resistance is composed of the resistance to heat flow through the material, the interfacial resistance at the external surface, and the interfacial resistance at the internal surfaces. Since the interfacial resistances are determined primarily by temperature conditions over which the builder has little control, his principal effect on the heat transmittance is on changing the resistance to heat flow through the wall material (Fathy, 1986). Figure (4) (Fathy, 1986) Table 2 lists the thicknesses of walls composed of various construction materials needed to achieve coefficients of approximately 1.1 kcal/hm ²C °. The mud brick is most appropriate for achieving thermal comfort in addition to being widely available to all segments of the population (Fathy, 1986). Table (2) Thicknesses of walls of different material (Fathy, 1986) Wall Material Wall Thickness Thermal Transmittance (in m) (in in) (in kcal/ hm ²C °) Hollow brick block 0.30 12 1.10 Double-wall brick with holes and 8-cm cavity 2 x 0.12 2 x 4.7 1.12 Brick wall with holes 0.38 15 1.03 Sand-lime brick 0.51 20 1.25 Hollow block sand-lime brick 0.51 20 1.16 Lime 0.51 20 1.10-1.35 Concrete 1.00 39 1.20 Orientation In hot climates, the sun is the major source of heat. The position of the sun must be determined for all hours of the day at all seasons as well as the direction of the prevailing winds, especially during the hot season. In addition, for an ensemble of buildings forming a sector, there will be reflection from adjacent buildings and wind screening by clusters of buildings, which contribute to a specific microclimate for each location in the sector. Wind movement and humidity also are important and should be considered simultaneously with the direct and indirect effects of the sun. The main objective is to establish the optimum orientation with regard to the sun and the prevailing wind (Fathy, 1986). Shading Generally, a building with a facade opening to the west is the worst case encountered in hot-arid climate, owing to the heat gain of the surrounding environment during the day and the angle of altitude, which allows the suns rays to penetrate into the interior. Openings Window openings normally serve three functions: to let in direct and indirect sunlight, to let in air, and to provide a view (Fathy, 1986). The venetian blind One device which can be added directly to the window is the venetian blind. This blind is made of small slats, about 4-5 cm wide, closely set in a wooden frame at an angle that will intercept the suns rays. The slats are often movable so the angle can be changed. This feature of adjustability renders venetian blinds very useful in regulating solar radiation and wind flow into rooms. Using the venetian blind, the suns rays can be blocked out without obstructing the breeze, which generally blows from the northwest in most hot arid areas like Iraq. As shown in figure 5a, changing the position of the blind alternatively by to block the direct sunlight, the wind is redirected uselessly over the heads of the occupants, as figure 5b illustrates. Also, if the slats are made of metal, they then absorb some incoming radiation and reradiate it into the room as heat (Fathy, 1986). Figure (5) (Fathy, 1986) The Shanshool or Mashrabiya This was a cantilevered space with a lattice opening, where small water jars were placed to be cooled by the evaporation effect as air moved through the opening. The name is used for an opening with a wooden lattice screen composed of small wooden balusters that are circular in section and arranged at specific regular intervals. The shanshool has five functions. These functions involve: (1) controlling the passage of light, (2) controlling the air flow, (3) reducing the temperature of the air current, (4) increasing the humidity of the air current, and (5) ensuring privacy. Its cooling and humidifying functions are closely related. All organic fibers, such as the wood of a shanshool readily absorb, retain, and release considerable quantities of water. Wind passing through the interstices of the porous-wooden shanshool will give up some of its humidity to the wooden balusters if they are cool, as at night. When the shanshool is directly heated by sunlight, this humidity is released to any air that may be flowing through the interstices. This technique can be used to increase the humidity of dry air in the heat of the day, cooling and humidifying the air at a time when most needed. The balusters and interstices of the shanshool have optimal absolute and relative sizes that are based on the area of the surfaces exposed to the air and the rate at which the air passes through. In addition to these physical effects, the shanshool serves an important social function: it ensures privacy from the outside for the inhabitants while at the same time allowing them to view the outside through the screen (Fathy, 1986). Table (3) Summary of architectural elements of traditional building in Iraq (hot-arid climate), as they have been common from the 13th to the end of the 19th century. Retrieved from http://www.brainworker.ch/Irak/architecture.htm Oda: the simple room Tarma: open balcony with pillars Ursi: most probably from russi, russian. The most important room of the house, as at the same time you may see, but not been seen as much as in a tarma, ivan or talar. Its separated from the tarma by a window-wall from colored glasses, without door. Those were the masterpieces of Baghdadi carpentry. Talar, a usable open room behind the tarma. The difference to the iwan is, that it cant be entered directly from the rooms beside it. Is separated from the tarma by additional pillars. Iwan(or Liwan), a room behind the tarma or adjacent tot the inner courtyard, that is on one side open. Hosh, the central courtyard, often with a fountain in the middle. sirdab, the cellar, that did not only serve as store, but   as cooling hall and for the provision of cool air through the badgir-sirdab-system. neem, a cellar that is only half buried. Mostly with one window. During the hot summer nights the roof was and is used in Baghdad for sleeping. The high value of privacy demanded, that no house was higher than the others, so that nobody was able to look down on his neighbors roof. kabishkan: The Penthouse, from where one is able to control all the house. Often those rooms have been placed like eyries in all four corners of the inner courtyard.   The roof If the outdoor air temperature is higher than the indoor temperature, the outer surface of the roof exposed to the sun is heated as it absorbs radiation, and, being in contact with the outside hot air, also is heated by conduction. The roof then transmits this heat to the inner surface, where it raises the temperature of the air in contact with it by conduction. At the same time, it radiates heat that is absorbed by people and objects indoors, thereby affecting thermal comfort. In hot arid countries, since the air temperature drops considerably during the night, the inhabitants have arranged the roof architecturally into loggias or open galleries and lightweight roof covers. These loggias and roof covers have the double function of shading the roof during the day and providing physiologically comfortable living and sleeping spaces at night (Fathy, 1986). Figure (6) Different types of roofing in hot-arid climates (Fathy, 1986) The wind-escape The technique of using the suction caused by low air-pressure zones to generate steady air movement indoors is used in the design of the wind-escape. The funnel and side tube used to illustrate the Bernoulli effect or Venturi action (see figure 7) are transposed into the structural elements of an architectural design in order to accelerate air movement and to create drafts in places with no exposure to the outside, such as basements in Iraq. This concept can be applied more advantageously in designs for use above ground. The wind-escape can accelerate effective ventilation and air circulation when used with other devices for air movement such as windows, doors, and the malqaf or wind-catch (Fathy, 1986). Figure (7) Bernoulli Effect (Fathy, 1986) The malgaf In hot arid zones, a difficulty is found in combining the three functions of the ordinary window: light, ventilation, and view. Therefore, it is necessary to satisfy the three functions ascribed to the window separately. To satisfy the need for ventilation alone, the malqaf or wind-catch was invented. This device is a shaft rising high above the building with an opening facing the prevailing wind. It traps the wind from high above the building where it is cooler and stronger, and channels it down into the interior of the building. The malqaf thus dispenses with the need for ordinary windows to ensure ventilation and air movement. The malqaf is also useful in reducing the sand and dust so prevalent in the winds of hot arid regions. The wind it captures above the building contains less solid material than the wind at lower heights, and much of the sand which does enter is dumped at the bottom of the shaft. In the areas of An-Najf and Al-Kufa in Iraq, where air temperature is very high in summer, people live in basements ventilated by small holes in the ceiling and a malqaf with a very small inlet. Figure 8 shows plans and the section of a residence with a basement from this region. However, as the airflow is small and the air circulation is insufficient, this design is unhealthy and a possible cause of lung diseases. In some designs, the drafts from the malqaf outlet are cooled by passing over water in the basement. Figure (8) The Malgaf (Fathy, 1986) The Bà £dgir-sirdab In Iraq (hot-arid climate)and the countries of the Gulf, a specific type of malqaf called the bà £dgir was developed.

Earth Science Final

Describe the difference in stellar evolution of stars the size of our sun with that of stars 4+ times larger than our sun. Include all of the steps and the causes of each step. A nebula, an immense cloud of hydrogen gas and dust, condenses into smaller regions of matter. On occasion, one of these regions collapses under the force of its own gravitational attraction, often triggered by an outside force, like a nearby supernova-an explosion of a star. After the collapse of a cloud, atoms begin gravitating together to form a condensed center.The condensed center is a protestor. As gravity pulls in more gas and dust, pressure builds, causing the protestor core to heat up. Clouds and matter begin to rotate around the protestor and flatten due to their rotation. They surround the protestor like a rotating disk. The protestor continues to grow and its core continues to heat. When the core is hot enough, nuclear fusion begins. The start of nuclear fusion is technically the beginning of a sta r's life. Eventually, when the nuclear energy runs out, the star dies.Depending on the size and mass of the star, it can go through many stages and die in different ways-one of those ways being a supernova. . Choose a region or landscape, describe the landforms in it, the drainage pattern, how the geology influenced the landscape, and the sacrificial processes that influenced it as well. Much of the region of western New York State north of the Pennsylvania border has dendrites drainage because rock layers are flat and there are few faults or folds to divert streams.A region that has prominent parallel and perpendicular faults, repeated folds, or a strong rectangular Jointing pattern will display a rectangular drainage pattern. Anoints are cracks in bedrock along which no significant movement has occurred. They may be related to expansion or regional forces acting on bedrock. ) Streams seek the lowest areas of folds, fractured rocks along faults, or the weakest surface bedrock locat ions. Annular drainage is a pattern of concentric circles that are connected by short radial stream segments.This type of drainage occurs in an eroded dome A radial drainage pattern resembles the spokes of a wheel. Streams flow away. Climate is the other major factor in landscape development. A humid climate favors chemical weathering, which produces rounded, less angular landforms. Most of the hill slopes of New York State are rounded and gentle because f the relatively humid climate. A moist climate also allows plants to grow and protect soil from erosion. Desert areas sometimes have a stepwise profile, with flat hilltops and terraces separated by steep escarpments.The climate of New York State does not change very much from place to place. All of New York has a moist, temperate, mid-latitude climate. Therefore the landscape differences in New York State are not the result of differences in climate. The variations seen in the New York landscape are caused by geological factors. 6. Link Ocean currents and the weather conditions of 3 specific regions. In each case, describe how the weather patterns of the place are influenced by one or more ocean currents.Winds, water density and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth's rotation results in the Acropolis Effect which also influences ocean currents. Similar to a person trying to walk in a straight line across a spinning Merry-Go-Round, winds and ocean waters get deflected from a straight-line path as they travel across the rotating Earth. This phenomenon causes ocean currents in the Northern Hemisphere to veer to the right ND in the Southern Hemisphere to the left.Rica, Chile lies within one of the driest regions on Earth called the Tacoma Desert. Ocean currents keep clouds and fog Just off the coast, so most rain falls into the nearby ocean. Dethroned, Norway has a temperate climate. Summers and winters are remarkably mild for their l atitude. Rainfall is very heavy. The local harbors are free of ice most of the winter. Seattle, Washington has a mild climate with temperatures moderated by the sea and protected from winds and storms by the mountains. This area is often cloudy with light rain.

Sole Proprietorship Sole proprietorship is the most common form of business in the United States. It is a relatively simple way for an individual to start a business since legal costs and business requirements are minimal, and the owner has complete control over the business. Though a sole proprietor is not responsible for any corporate tax payments, the owner is responsible for taxes incurred on the income generated from the business as part of his or her personal income tax payments, and personally shoulders any other risks or obligations. A sole proprietor may also choose to file their business under a fictitious business name or a DBA (doing business as), allowing him or her to operate and market the business under a more typical†¦show more content†¦Liability All liabilities are the responsibility of each partner. In the event of litigation, any creditors can go after the personal assets of each partner to recover any debt owed. But since liability is spread out between the owners, one may feel less risk is being taken. 2. Income Taxes General partnership may also benefit from pass-through taxation, meaning the partners are taxed like sole proprietors. Business income is reported on the personal tax filing while business losses can be deducted to reduce personal tax liability. The partnership itself is not subject to federal income tax. However the partnership needs to file an information return utilizing the IRS Form 1065. 3. Longevity or continuity of the organization Once the partnership agreement is fulfilled, the general partnership may dissolve. A buy/sell agreement may be included in the articles of the partnership to allow the partnership to continue, in the event a partner withdraws from the group. Similar to sole proprietorship, general partnerships tend to have a difficult time rounding up funding and resources, since most of the necessary capital comes from each partners personal assets. This in turn may hinder longevity and growth of the organization. 4. Control In a typical general partnership, all partners will have equal rights and control over the business.

The Road Not Taken Analysis Author: Poetry of Robert Frost | | Mountain Interval1916Two roads diverged in a yellow wood, And sorry I could not travel both And be one traveler, long I stood And looked down one as far as I could To where it bent in the undergrowth;Then took the other, as just as fair, And having perhaps the better claim, Because it was grassy and wanted wear; Though as for that the passing there Had worn them really about the same,And both that morning equally lay In leaves no step had trodden black. Oh, I kept the first for another day! Yet knowing how way leads on to way, I doubted if I should ever come back.I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a†¦show more content†¦Third, its almost as if a coin could be flipped to make the decision, because, as (3) shows, the choices are nearly identical. The person could have flipped a coin or do some other arbitrary technique, but he decides to personally make the choice. Fourth, I get a sense of regret about not being able to take the other road and also not being able sometime in the future to go back and take the other road. This is logical I think because of the similarity between the roads. This may be what with a sigh is referring to, since it is just one line below the doubted line. I like this meaning because it kind of fits. In the future, hes still lamenting that he hadnt been able to take the other road, which would have led to much a different result. Fifth, when does this contemplation take place? Ages and ages hence. That is, when one is much older and new choices are not available. Putting this all together, there are many things a person could become: for example, go one way and you might become a teacher; go another way and you might become a writer. Both are good things to become and you can understandably wonder how things might have turned out, if you had made that other choice. When you make the choice, at that time, you may not see a major difference between the two options. But the choice that you made is decisive. It determines your future. â€Å"The Road Not Taken† Complete Text Two roads diverged in a yellow wood And sorry I couldShow MoreRelatedThe Road Not Taken Analysis987 Words   |  4 PagesThe Road Not Taken Analysis The Road Not Taken is a poem written by Robert Frost.
