Isle of wight ventnor - Essay ExampleIn addition, the oceanbed forms a ridge ascending to 15 meters of the surface that causes the sea to rush in between the ridge created and the Island. Due to this, there exists a narrow deep channel called the St Catherines Deep. The worry Study of the geotechnical situation in Ventnor indicates that the town has experienced landslides subject to underfur movements. These landslides cause damage to property and interrupt the delivery of services mostly through with(p) through pipelines. The under-cliff of the Isle of Wight is 12 kilometers long. In 1988, the Department of Environment in Ventnor commissioned a study to come with ideas for dealing with the land mental unsoundness problem. To understand the problems of stabilizing the town of Ventnor properly, it is important to consider 1. The nature of the landslips 2. Study the strategies used to reduce negative impacts in the future and their applicability 3. Investigate the foregoing case s of instability It is very crucial to note that only some areas in the town of Ventnor experience landslips. In fact, various developed areas do not fasten affected even by main events. Consider the Bonchurch Old church which is over 1050 years old and still exists. Researchers tend to misinterpret the extent of the landslides since they complicate buildings and property that crumble due to poor foundations. Consequently, the problem appears great and non-manageable. (Griffiths, 2001). Location map The location of the town of Ventnor creates a problem in the stabilization of the area. The town faces a sea with various activities among them sea bed movements. Its open side facing the sea presents the problem of vulnerability due to lack of protection from sea tides and strong winds. Instability due to ground movements Ground movement continues to be a problem in the stabilizing of the town of Ventnor. The worst period occurred in 1961 where cliff falls and collapsed settlements we re rampant following heavy autumn rainfall. Although the records date as far back as 1781, it is not easy to get a clear picture of the problem of ground movements. 91% of the town has had minimal movement annually and short term major movements are attributed to long get away movements. In the last 100 years, ground movement has become a challenge to the local community. This problem is independent of financial influence since it is a inseparable occurrence. The continued development of the area based on urbanization increases human traffic thus, adds to the initial ground movement activity. Sir William 1997 argues that ground movements result from slope instability, ground compression and subsidence. Initially, the under cliff was a result of various phases of landslides due to climate and sea level influences. Landslides in Ventnor appear in the cretaceous rocks which lie in of Gault body overlain by big sandstones and chalk. The thin clay layers and the Gault clay determine t he stability of the area. It is evident that the geotechnical design of the town of Ventnor is itself a problem to the stability of the area. Landslides The images to a higher place show the occurrence of landslides which create a challenge in stabilizing the town. Mostly, landslides in Ventnor occur due to planes of weakness that come beneath impermeable clay surfaces. Water seeps through layers of sand leading to instability due to erosion. This image above represents the anatomy of the landslides. Landslides occur at the under-cliff of Ventnor located to the south of

Construction Project Management - Essay ExampleCurrent communicate demand for planned wrap farm verbalism ranges between US$ 8 10 billion, based on an estimate of US$ 200 one million million for 50 MW wind farms (European Bank, 2011 and Bobylev, 2009). Wind power in Russia is still low compared to other European countries. Thus, the following are some of the anticipated large projects in RussiaHowever, it has been observed that factors much(prenominal) as corruption, differences in language and culture, a tendency by the government to indulge in politically motivated campaigns against foreign firms as well as terrorism are likely to pose problems to investors. However, given the lucrativeness of the construction industry in Russia, it is possible for Natural Power Consultants to overcome such difficulties. It has been proposed that a cautious approach has to be taken upon entry into this market. The company must have something to offer and the impact of corruption should not be ignored.This prick of the study seeks to critically analyse information about Russia, its construction industry as well as various cultural issues that often shape the operations of organisations in this country. Thus, according to Datamonitor (2011b), the construction and engineering industry in the Russian Federation shrank by about 20 percent in 2009. Although most of the construction within the energy sector emphasises oil and gas pipelines, Russia has on-going wind farm projects. These include the ones within the 50 150 MW rated capacity range (European Bank, 2011). Recently, Russia announced a plan for investment of about US$200 million for what is yet to become the largest wind farm project in the country. This includes the 50 MW city of Yeisk wind farm located on the coast of the Sea of Azov (RIA Novosti, 2010). Based on a construction cost figure of US$200 million / 50 MW capacities for a wind farm in Russia, the following relatively large projects

Biodiesel as an Alternative Fuel Essay Example for Free

Bio diesel engine as an Alternative Fuel EssayAs time goes on, humans ar discovering new ways to make better their means of living. Whether the upgrade affects us financially, socially, or if it helps the Earth, or better health and education, things are changing. Multiple enhancements in fueling ones car consume risen. Gas has become pricey, and the controversial argument that oil will one day perish are factors that have led people to find early(a) alternate(a)s. Biodiesel is an efficient alternative fuel, for the reason that biodiesel is a safe, eco-friendly, and affordable option. Biodiesel is a clean burning alternative fuel. It is renewable and generated from a variety of vegetable oils and animal fats, non raw vegetable oil. Raw vegetable oil cannot be utilized because it has not undergone the process of transesterification. Transesterification is a process in which oils and fats are obtained organically and are combined with alcohol with the help of a Catalyst to f orm esters. Biodiesel can be used either in its pure form of 100% biodiesel, or can mix with crude oil as a biodiesel blend (ex B20, 20% biodiesel, 80% petroleum diesel).Biodiesel began in the 1890s with Rudolph Diesel. Diesel thought early diesel engines could run on pure vegetable oils and believed there would be a grand benefit to those living in poor areas where there was no petroleum. The contemporary biodiesel that is derived from the transesterification process did not surface until the 1930s in Belgium. But todays biodiesel really began in Europe in the late 1980s. The early diesel engines ran on many substances, until vegetable oil seemed to be an efficient alternative.That is when Rudolph Diesel got to work and researched vegetable oil, concluding farmers could make their own fuel. However, Diesel died a poor while after and petroleum became found in many forms. There was abundance of petroleum and in low represent, so the diesel engine was changed to hit diesel petro leum fuel. The petroleum diesel spread quickly and biodiesel was ignored. Yet, the biodiesel industry kicked off after the transesterification process was launched and became a preferred method as an alternative fuel.All good things are flawed, and biodiesel does include some disadvantages. The production of biodiesel can result in more land use. If many of us switch to victimization biodiesel, there would be much land devoted to our biodiesel fuel needs. Biodiesel transportation and reposition can be a hassle. Since biodiesel does not flow well during winter, storage can become an issue. Also, biodiesel cannot travel in pipelines. A truck has to transport it, resulting in higher cost. Biodiesel becomes a gel in cold weather and does not flow therefore one can experience driving difficulties in the winter time. The diesel creates wax crystal which can clog filters and fuel lines in your cars fuel system.Even with its disadvantages, biodiesel has not become a popular alternative fue l for nothing. It has many advantages that persuade people to make the switch. Biodiesel is cushy to use, and any vehicle can be converted into a diesel engine car. Also, because biodiesel can be blended with petroleum diesel, one could switch from biodiesel to petroleum whenever wanted, without having to make any changes. Biodiesel pumps at gas stations across the country are growing daily. Pure, 100% biodiesel will have about 5%-10% little energy than petroleum diesel. Usually people notice very little change in their mileage or performance. When using a biodiesel blend, the numbers change. exploitation B20, there is less than 2% change in energy and users notice no change in mileage or performance.Using biodiesel is an advantage that is greatly helpful to the environment. Biodiesel is nontoxic, causing less damage than petroleum diesel if it is spilled or somehow released to the environment. It is also safer than petroleum diesel because it is less able to explode or catch on fire. The combustion temperature for biodiesel is higher than 150C, and about 52C for petroleum diesel. Biodiesel is safe to handle, store, and transport. B100 use reduces carbon dioxide emissions by more than 75% compared with petroleum diesel. Using B20 reduces carbon dioxide emissions by 15%. Also, in both soil and water, biodiesel degraded at a rate 4 times fast-paced than petroleum diesel.Because of its clean nontoxic emissions, easy use, and many other benefits, biodiesel is becoming one of the fastest growing alternative fuels in the world. Due to its expense, biodiesel is cost private-enterprise(a) with petroleum diesel. Millions of users have switched to using biodiesel and are enjoying its benefits. If we create biodiesel in a reasonable manner, it can help the world with the topic of petroleum supply. Its clean, renewable, and cost effective fuel will provide us with economic and environmental advantages for the future.

Women in the Workforce Essay Example for Free

Women in the Workforce EssayAs a young a muliebrity living in the 21st century I can only believe that women have every reason to be part of the workforce. In instantlys world advancement we have all the technology needed to be able to create balances between our family and work life. In the old old age women were viewed to be weak compared to men, because jobs required more physical abilities then mental and critical thought process abilities. Therefore, men were apt(p) the working part of the familys creation and women were given the care giving for the children part. Today, things are different. Jobs have turned from being only physically oriented to rather more problem solving and thinking oriented.And this makes more opportunities for women to join the workforce. Moreover, I think women should join the labor force because it is proven that when a woman in a family is working it is more seeming that the family will rise above the poverty line. Studies done in Banglades h by Mohammad Yunus, the founder of the micro financing Grameen Bank, show that when the woman in a family is given a jeopardize to generate income for her household she always does a better job with helping her family out of poverty.Women are care givers in nature, and when given the chance to improve the living standard of their childrens lives they will do a better job managing the money and finances. My final reason is that I think in the end, woman or man, we as humans should be given equal opportunities to explore our full potential. No effect what kind of job or fashion or hobby we might be doing, we should all be given the chance to thrive and prosper in this life with no restrictions. No matter what race gender or ethnicity we should all be able to do what we love.

Wolves Communication Pack

Wolves conference PackCOMMUNICATION AMONG WOLVESABSTRACTJust like any gradati peer slightr(a)(a) beast wolves communicate with each some other, with most of its conference being a middle rent members. Wolves use three differing types of communication 1) Vocalizations Wolves atomic number 18 frequently heard at iniquity because it is when they are most active. Wolves howl for umteen reasons, particularly to show up other members of the channel and to warn outside wolves to stay a focal point from an occupied area. 2) Scent fool Wolves possess a real keen sense of smell (about 100xs greater than humans). Wolves use this ability aprospicient with the others to communicate with other wolves. Scents are employ to start pack territories or l maven wolf territories. These territories are marked most often by urination and defecation on or around trees and other objects. In addition to these two means of smelling marking wolves also aromatize mark by scratching and scent rolling. And the last method of communication 3) Body postures Wolves also use consistency language to communicate, whether it is to others in the pack or outside of the pack. Some postures are used to show affection, some forethought or humiliation, others happiness and even others privy emanate respect between pack members. All are important and used by wolves on a daily basis, whether it be to warn collide with competing packs, communicate a fresh kill or to portray controller.INTRODUCTIONOne of the things that distinguish different members of the family family Canidae is the differential development of mixer behaviour. Among the close relatives of the domestic dog, the most highly social species is the wolf. Wolves belong to a family concourse often referred to as a pack. This social structure was originally thought to allow the wolf, a social predator, to take prey many times its size, however new theories are emerging suggesting that the pack strategy instead maximizes reproductive success and has less to do with hunting. They live, travel and hunt in these packs which consists of anywhere from four to fifteen members (pack sizes are subject to reposition overtime and are controlled by such things as food supply, individual personalities and habitat type). The rare exception is the l unmatched wolf, this wolf will most probable be the omega wolf, the lowest ranked member of the pack, and if it is lucky will find a mate and start a new pack. Wolf packs ready a rattling elaborate hierarchy, one in which is topped by the alpha male and female, followed by their pups, often several sub-adults from the previous years hatch and sometimes some older siblings as well. When pack sizes are large (usually a lot then 8 members) it is possible to witness two differing hierarchies in one pack, one in which is the females being led by the alpha female and the other the males being led by the alpha male. The alpha pair handle the most social freedom among all pack members, they are very influential and simply have the most freedom in where to go, what to do and when to do it, with the rest of the pack usually following. The alpha male and female therefore usually direct the pack in hunting and tracking prey, choosing den sites and establishing and maintaining the packs territory. run order is ascertained and sustained through a series of ritualized fights and posturing best expressed as ritual bluffing. Wolves prefer physiological warfare to physiological confrontations, meaning that the higher ranking status is based more on personality or attitude rather than on size or bodily strength. Rank order whitethorn be lost rather suddenly or gradually. An older wolf may simply choose to give way to a motivated challenger, yielding its position without bloodshed. On the other hand the challenged individual may opt to fight congest with varying degrees of passion.Wolves communicate use three main strategies 1) vocalizations- howls an d growls 2) facial expressions and body postures and 3) scent marking. scream alone can have a variety of meanings a greeting, a rallying herald to gather the pack to get ready for a hunt, an advertisement of their presence to warn other wolves away from their territory or spontaneous expression of hunt down and bonding. The howl of a wolf can be heard up to six miles away making it the most useful means of communication accustomed that wolves couch over large distances while hunting and traveling. Wolves engage in a variety of displays of dominance, and submission that helps reinforce the hierarchy in packs. Wolves use their good bodies expressions of the eyes and mouth, the position of the ears, phantom, head and overall position of the body are used to convey excitement, anxiety, aggression or compliance. Wolves also wrestle, rub cheeks and noses and nip and flail one another. They leave behind messages for themselves as well as other pack members by means of urination, d efecating or scratching the ground to leave scent marks. These marks can set the boundaries of territories, record trails, warn off other wolves or help lone wolves find unoccupied territories. In a exchangeable fashion wolves will roll around in items with a strong scent such as carrion as a way of letting other pack members know where they have been or what it has encountered. In the end it can be said that the habits of the wolves require members of a social unit to be visually separated at times so that these olfactory and auditory means of communication are possible ( Berge, 1967).VOCALIZATIONS The wolf is a across-the-board ranging social carnivore with a complex spatial organization for which acoustic communication plays an important role (Palacios et al. 2006). There are four kinds of vocalizations that are popular among wolves, they involve the growl, the whimper, the bark and the more associated cash in ones chips of the wolf, the howl. Any one of these or a combinatio n of these allows the wolves to communicate with one another. The bark can be used over long distances and can take on the roll of sounding an alarm or presenting a challenge. The alarm bark is most often used when a wolf is caught off guard and surprised at the opening of its den, and a challenge bark is a warning for a wolf to back off when two wolves are encountering a face off (a fight). The growl has similar meanings to the bark however it is used in shorter distance communication. It is used to keep other wolves away, to reinforce dominance and, it can also be used at short range to challenge. The whimper is used at short ranges as well and portrays a extroversive stance (often used by young to receive care). The howl, the most well known figure of communication among wolves, seems to have many complex functions and will be looked at in greater detail compared to the other three types of communication listed above.Howls allow wolves to communicate over several kilometers. Ho wls have been described as long harmonic sounds with a fundamental frequency from 150Hz- 1000Hz for adults. There have been two types of vocalizations involving howls that have been recorded 1) Solo howls and 2) Chorus howls. Solo howls, also referred to as a lonesome howl is emitted by a sole individual. In the study down by Berge many years ago unique features were found to pull round in individual howls. Harmonic characteristics were found that would distinguish individuals on the basis of any one howl. Therefore the variation in structure likely indicates who is ululate and the frequency modulations, predominantly the change in pitch makes the howls much easier to locate. The ability of a wolf to detect these very subtle changes in sounds indicates that a reception to this information is possible (view figure 3). As with any form of behaviour there is a hail/benefit to this action. The lone wolf is just that, it is alone, and when producing sound its pack mates are not the o nly ones who pick up the vocalization, thus this behaviour could turn out to be detrimental. However with any cost comes with it benefits, a lone wolfs howl can help one locate the other members of its pack proving to be advantageous. A chorus howl on the other hand has been described as a vocalization in which one wolf begins yell, with the other members joining in subsequently until the whole pack is howling together. Rather than using howls with a single pure tone, wolves use modulated tones. With the rapid changes in pitch it makes it very difficult to follow only one individuals howl, and to add to it the surrounding environment helps reflect the sound and scatter it making it extremely challenging for a competitor pack to distinguish where the pack is and how many members the pack consists of.The heart of a wolfs universe is its pack and howling could be the adhesive that keeps it together, suggesting that howling may reinforce the social bonds between pack members as well as keeping the pack safe. In view of the fact that wolves are separated great distances during a hunt, it is not unlikely that howling keeps the pack as one physically. Of all their calls howling is the only one that works immensely over great distances. Its long duration and low pitch are what make it suitable for long range communication through the forest and in tundra areas. Its unique features are what allow a wolf to convey its identity element and each wolf can be identified by its pack just by means of its howl.SCENT MARKINGWhile howling may provide much information about a wolfs whereabouts elaborate spatial patterns of scent marks provide precise information about inhabited territory. A territory is a space within which an animal is aggressive to and usually dominate over certain intruders (White et al, 1996). It is a silent way of steering drop dead of violence that would otherwise be required to preserve a territory. Scent marking can also provide a silent exchange betwe en animals that share territories and can also help an individual keep its point of reference when traveling. When Roger Peters and David Mech conducted studies on a variety of wolf packs in the Superior guinea pig Forest of northern Minnesota they found that wolves scent mark using four differing methods. The first method is by means of raised leg urination. This form of scent marking is closely connected with territorial marking and maintenance (Macdonald et al. 1998). These markings are made throughout the territory and heighten in concentration at the limits of the territories. The alpha male and alpha female are the primary users of raised leg urination (more often it is the alpha male) with only few instances where it will be used by other wolves. The second mode of marking is squat urination. This mode of urination is the ordinary form of urinating, and is performed by the lower ranking individuals in the pack. This method of scent marking supplies them with information abou t which fraction of the territory has been hunted during times of separation. Scratching, and or scent rolling the third strategy to scent marking involves a wolf that may rub its lips and neck against a tree or on the ground or scrape the ground with their paws (normally after urination) to mark out their territory. Scraping, usually with the hind legs and sometimes also done with the front is predominantly performed by the dominant individuals, the alphas (can be done by mid ranking individuals depending on the circumstances). Wolves have scent glands between their toes which release odours/ a characteristic scent. The wolf has several specialized glands, located all over the wolfs body that function as a chemical and a visual message for other wolves. There is one located near its anus ( anal gland), another on its back, one at the tip of its tail (precaudal gland), in its eyes, behind its ears, on its cheek near the corner of the wolves mouth and between their toes (as mentione d above). The aroma from these glands is as individualistic as our own fingerprints. Each scent is specific to an individual each with its own meaning. Scats also referred to as defecation is then the fourth means of marking. Again this form of marking is very similar to that of urination and serves many of the same purposes. However here it acts as a more visual warning. hither again the anal scent gland becomes important. It produces a pungent oily pheromone that is excreted during bowel movements, thus scenting the wolfs scat with his/her own odour. The exact purpose of this means of scenting is unknown however it could very well be that these anal scent glands play an imperative role in wolves of higher ranking for it has been observed that when higher ranking individuals meet they smell under the tail, this action is not performed by submissive wolves (lower ranking wolves). (Refer to figure 1 and table 1)Olfactory communication is defined as the process whereby a chemical sig nal is generated by a presumptive sender and transmitted to a presumptive receiver who by means of adequate receptors can identify, integrate and respond to the signal ( Kleiman, 1972). Scent plays a exceedingly imperative role in the life of a wolf, by smell alone wolves can locate prey, other pack members or enemies. It can come apart them if other wolves were in their territory, if they were male or female and how recently they were there. Therefore marking can be used for non-territorial purposes as well. It can also be used to identify individuals, lay claims to a kill, for navigational purposes during those long ranging hunts and can also be used as a indication for sexual receptivity during couple season ( suggested that this is the purpose of sniffing under the tail upon greeting).BODY POSTURESWolves convey their emotions through body language. Here they can communicate visually a number of expressions and moods that range from subtler signals to more obvious ones (Berg, 2003). The following are observed behaviours. Wolves display dominance by standing(a) tall and stiffed leg. The ears are erect and forward and the tail is held vertically and curled toward its back. This demonstration declares the wolfs rank to the rest of the pack. Submission can take the form of both active submission or passive submission depending on the circumstances. In active submission the wolf lowers its entire body toward the ground and the lips and ears are move back, in essence the teething are bared. The tail is down and either half way or completely between its legs (depends on level of submission) with their laugh (refer to figure 2) pointing up toward the more dominant individual. The back will be arched and again depending on the level of submission the back may be arched more or less. During passive submission, a more intense form compared to active submission the wolf will roll over onto its back and render its susceptible throat and underside, with the paws b eing drawn into the body. If a wolf is displaying anger its ears will be erect and its fur may bristle. Here the teeth are bared and it is usually accompanied by a snarl or growl. When a wolf is fearful it tends to make itself look small and less conspicuous. The ears flatten and again the tail is tucked between the legs. If a wolf senses danger suspicion will arise. This is displayed by the pulling back of the ears and the narrowing of the eyes. The tail will be parallel to the ground and pointing straight out. A playful wolf will hold its tail high and wag it. The wolf may frolic and dance around, or bow by placing the front of its body down to the ground all the while holding its rear in the air. (Table 2 summarizes body postures)CONCLUSIONSWolves are multifaceted social animals whereby communication signals are used for a variety of purposes. In order to function as a group communication among individuals in a pack is crucial. Communication is used for recognition, reproduction, social status, alarm, foraging and group spacing also referred to as territoriality. The wolf is a wide ranging social carnivore with a complex spatial organization for which acoustic communication plays an important role (Palacios et al. 2006). There are four kinds of vocalizations that are popular among wolves, they include the growl, the whimper, the bark and the more associated sound of the wolf, the howl. Any one of these or a combination of these allows the wolves to communicate with one another. While howling may provide much information about a wolfs whereabouts elaborate spatial patterns of scent marks provide precise information about inhabited territory. Scent plays a very important role in the life of a wolf, by smell alone wolves can locate prey, other pack members or enemies. It can tell them if other wolves were in their territory, if they were male or female and how recently they were there. Therefore marking can be used for non-territorial purposes as well. It can also be used to identify individuals, lay claims to a kill, for navigational purposes during those long ranging hunts and can also be used as an indication for sexual receptivity during mating season. Wolves communicate at close range their emotions through body posture, tail positions and facial expressions. Here they can communicate visually a number of expressions and moods that range from subtler signals to more obvious ones (Berg, 2003).
