Piezometers( to measure the water table to monitoring landslide) Essay

Piezometers( to measure the water table to monitoring landslide) - Essay Example Appropriate design of drainage system is possible only if the water flow pattern within the rock mass is understood; and for this purpose, the measurement of hydraulic conductivity and water pressure are carried out. Piezometers are used for measuring water pressure within a slope in order to control the stability of the slope by drainage. Piezometers are devices that are sealed within the ground, generally in boreholes. They respond only to ground water pressure in the immediate vicinity and not to ground water pressure at other locations. Piezometers can also be used to measure the in situ hydraulic conductivity of rock masses, using variable head tests (Wyllie et al, 2004: 120). The purpose of this paper is to discuss the role of piezometers in preventing landslides, identify the different types of piezometers, examine the advantages and disadvantages of each type of piezometer, compare the type of soil that they can be used in, and their applications. Piezometers measure groundwater pressures, which is useful for â€Å"effective stress stability analyses of landslides and to observe the variation of pore pressure vertically in the landslide† (Cornforth, 2005: 82). Certain factors have to be taken into consideration when planning a piezometer installation to measure water pressures in a rock slope. It is important that the drill hole should intersect the discontinuities in which the ground water is likely to be flowing. For example, the hole should intersect the persistent beds in sedimentary rock which has low persistence joints. Zones of fractured or sheared rock should be located for positioning the completion zone of the piezometer, since ground water flow would be more concentrated in these areas. The length of the completion zone in rock is usually longer than in soil, because of the requirement to intersect discontinuities. Fault zones are geological features; if they contain crushed rock

Promoting diversity within a health and social setting Essay Example for Free

Promoting diversity within a health and social setting Essay In this report I am going to outline The Mental Health Act alongside this, the procedures and codes of practise and how both of these aim to promote diversity and assessing the effectiveness of these measures in place. The Mental Health Act aims to safeguard the vulnerable, by ensuring they are treated fairly and equally by services and given permission to health care, for example hospital treatment if required. The term mental illness or a personality disorder is used to describe someone with a mental disorder. The key principles of the act include keeping the service users best interest at heart and if unwise decisions are made by the user, the least restrictive option should be made. The mental health acts helps to promote diversity, because it ensures that the individual themselves will not be taken advantage of and their choices are met with full understanding before a decision has been made. This also makes sure that the person who holds the right to overrule the decision making follows under the act closely. The codes of practise aim to provide rules and regulations on how professionals should behave in a health and social care service. Most importantly, they provide specific standards of practise for each situation. For example, there is a code of practise for nursing and midwifery, known as ‘the nursing and midwifery council’. Another example of how codes of practise provide specific rules for each situation is the including standards of practise specially tailored for social care workers. This is known as the ‘General Social Care Council.’ The standards of practise must comply with the employers and employees responsibilities non- discriminatory practise. These responsibilities include staff promoting choices about service users and the care they receive; promoting a sense of self – concept for each service user; promoting diversity by considering their preferences, the service user’s individual needs and their wishes being taken into consideration of every aspect of their care. These responsibilities help to promote diversity, because it prevents victimisation and respects individual’s different views, with providing equality for all and promoting non – discriminatory practise. Overall, this piece of legislation is effective, because it aims to promote diversity by providing important legislation with lawful regulations that helps to meet service user’s needs. For example, the mental health act ensures the individual focused on if necessary, will be ensured to have informed and respectful decisions made based on their needs and preferences. Codes of practise are effective for aiming to promote diversity, because they provide standards of practise for individual situations, which all consequently aim to promote diversity and help staff and carers to use non – discriminatory practices that respect all individual service user’s needs while also aiming to promote and respect differences within each individual.

Inventory Planning and Control

Inventory Planning and Control A Brief Overview of Inventory Planning and Control In any business, inventory is a key area of concern as inventoryis what is sold. Though, on the surface this may seem to be merely aphysical construct, inventory and inventory management principle easilyextend to service or other intangible product offerings. Perhaps the firstprinciple of inventory is that, inventory is money, or rather arepresentation of invested capital that is listed on the balance as aliability. While inventory is properly represented as a liability, a moreaccurate way to think of it is that is an asset in the waiting. Atypical retail store may have millions of dollars in inventory on the floor.If it is the right product, priced right, in the right place at the right time,it will likely sell. Though the 3-Ps just mentioned are the crux of themarketeers problem, they are also the problem of the inventory orreplenishment analyst on the store side and the problem of the manufacturingand shipping division of the supplier. Boththe vendor and the supplier seek inventory optimization, that is,managing from their perspective the same issues with which the marketeerwrestles. The daily issues of this perspective are focused on the same fourvariables with typical examples listed below: Product Is a certain SKU present in the regular modular only or checkout lane modular also? Are there multiple SKUs for a certain product (i.e., single or multi-packs)? A new SKU is being phased in to the modular set, is the are corresponding reduction in another product? Is replenishment on the old item turned off? If I have a certain product, is there a complimentary product that should also be sold, ideally with modular adjacencies? Placement Is a particular product in all stores (i.e., riding lawnmowers in NY City, snow shovels, even in January, in Mexico)? Does this product go into all stores simultaneously or should it be staged (i.e., lawn care product in southern stores first)? Are there any new stores that should be added to the shipped to list? Is a particular product a regular item or does it go on a special display/store location (i.e., holiday)? Price Are all the prices indicated on the shelf or on the product? Are the prices correct? Are prices updated annually or monthly? Is the item on deal (i.e., advertised special for which we might anticipate the standard 20% lift in velocity)? From theperspective of the vendor, a store or even a whole chain of store only has a[short-term] fixed floor area, backroom area and so many storage areas andtrucks that can be in transit to manage not simply one product at one locationbut the full range of products at all locations. This, in essence, is theproblem of inventory: managing and ideally optimizing the coming and going of allproducts at all locations. For the manufacturers, the problem is essentiallythe same, only with a different perspective: all of their products atall of the locations at which they are sold. The daily issues of this simply detail.Consider the perspectives of WalMart and 3M: one US retail operation and theone US division of one multinational manufacturer: WalMart has approximately 3,000 US stores, if there is one case of one product from 3M going to each store in the chain, this alone represents shipping 36,000 items (12 per case) just one time. Consider the number of products shipped, received and sold for all products at each store. 3M Stationary Products Division, Tape Adhesives section, has over 50 SKUs. Each peg on the display holds from 6 to 15 units of product. Each product comes in varying numbers per box, from 4 to 24, with from 1 to 6 boxes per case (the minimum order quantity). WalMart has the largest trucking fleet of any US corporation and has number distribution centers and warehouses. 3M has 1-2 factories per product and 3-4 key distribution points. Some items are warehouse items and therefore have a lead time of 3-4 days while other items have lead times of up to 21 days. The myriad issues that result from this collaborative efforts issignificantly enhanced but the good management of the inventory problem.From the number of units to build and subsequently ship (and to where) untilthe items are sold, the units exist as inventory. A Brief Discussionof EOQ and other Methods for Inventory Control To manage the issues discussed just prior is but one matter, tomanage them optimally is another and that is really the goal of anyinventory planning and control system. Realizing that any businessdecision is one in which the principle of the trade-off is employed, one canthen begin to methodically examine the variables. For example, in the simplestexample in which the costs of placing an order and the costs of carryinginventory are minimized. This optimal point is deemed the Economic OrderQuantity. While, in theory, the method works perfectly, its simplicity is alsowhat limits it in the real world in which additional variables and varyingassumptions run rampant. For example, EOQ does not, or, has trouble takinginto account the following variables/assumptions: Product cost assumptions such as fixed batch costs Product prices which may be variable and thus would change velocity and subsequent sales/demand forecasts Failure to adequately consider or cost out of stocks or backorders Failure to adequately consider lead times, special deals or seasonal items (Eason, 2003). Regardless, EOQ isthe starting place for the consideration or both additional variables as wellas the consideration of other models such as JIT, or the just-in-time methodin which the goal is -0- inventory. This is more applicable to a manufactureside though its principles do have applicability in retail. In this method,the basic assumption that has generally been borne out through research is thatinventory carrying costs are generally far higher than one might initiallythink (Schniederjans Cao, 2001). JIT is achieved by precisely the rightquantity of material/product to its destination just-in-time. Anothersomewhat similar method is ERP or enterprise resource programs. ERPleverages technology to provide firm-wide view of the materials at variousstages in the work process. This data is merged with other firm informationsuch as sales/demand forecast to create a optimized forecast for all rawmaterials, parts and finished products at any point in time. Insummary, whether using EOQ, JIT, ERP or any other combination of letters forinventory optimization, the key is to understand and purposefully manipulatethe variables of business to prioritize and manage the inherent trade-offs ofany business function.

The Taming of the Shrew Essays -- English Literature Essays

The Taming of the Shrew Examine the different ways in which Shakespeare presents the attitude towards marriage in the play, ‘The Taming of the Shrew.’ The Taming of the Shrew is one of Shakespeare’s earliest comedies, and it shares many essential characteristics with his other romantic comedies, such as Much Ado About Nothing and A Midsummer Night’s Dream. These characteristics include light-hearted and slapstick humour, disguises and deception and a happy ending in which most of the characters come out satisfied. The play has been dated from as early as 1594 and as late as 1598. (http://www.sparknotes.com/shakespeare/shrew/context.html) The main themes in the play are love, marriage, domination, society expectations, betting and money. Does love really exist in the play or is it just love for money. It seems that the key to a happy and successful marriage is money. This comedy written by Shakespeare uses disguises and that also is a key part to the play. Although it is intended to be a comedy, there is sometimes a black cloud hanging over it. For instance the way in which Katherina is treated doesn’t always seem to be funny; instead it is quite cruel and degrading. â€Å"She eat no meat today, nor none shall eat; last night she slept not, nor tonight she shall not.† (Page 62, act 4 scene 1 line 182-183) Men saw marriage as a way to get rich; love didn’t even enter the equation. Padua is a rich area and therefore many suitors fled there in the hope of becoming wealthy. â€Å"I come to wive it wealthily in Padua,† says Petruchio. He asks outright, â€Å"Then tell me – if I get your daughter’s love, what dowry shall I have with her to wife?† (Page 37, act 2 scene 1, line 119-120) The husbands were given a dowry by the father of the daughter when they became married. Women didn’t have any say in who they chose to marry; instead the decision was given to the father. If a daughter was not married then they were looked shoddily upon within the society. In this era every woman was to be married otherwise they were frowned upon within the community. Further more without Katherina getting married, Bianca would also never marry. Within a family the eldest daughter must be married off first and in this play turned out to be a bonus. â€Å"Her father ke eps from all access of suitors and will not promise her to any man until her elder sister first be wed.† This is the main an... .... She now obeys what is asked of her by Petruchio like such as when she is told to lecture the other wives about how to be a good wife, â€Å"Katherina, I charge thee, tell these headstrong women, what duty they do owe their lords and husbands.† Without arguing and saying a word against what is asked of her she gives her advice, â€Å"Thy husband is thy lord, thy life, thy keeper, thy head, thy sovereign, one that cares for thee.† Women in the Elizabethan era were presented as very obedient to their husbands and respectful to them also. They had no power and no say, they were treated badly and nothing would be done to stop the behaviour. In modern society most women have as much say as the men, they are not expected to stay at home and clean etc, and instead they go to work as well. Some women are like Katherina before she was supposedly tamed, very out spoken, yet inequality still exists. During the Elizabethan era marriage was like a business contract, if the money is there then so is the signature. Love was never a part of the play and this showed in both Hortensio and Petruchio, who Shakespeare uses to expose this superficial approach to the supposedly romantic notion of marriage.

LTG. Timothy J. Maude.

Lieutenant General Timothy Maude was killed on September 11th 2001 in Pentagon attack. He had been serving as Deputy Chief of staff for Personnel in the army. He was born on 18th November 1947 in Indianapolis in India. His long character of understanding human spirit will never be forgotten. According to him, the well being of civilians, veterans, families, retirees, and soldiers was determined by the concept of readiness within the force. The success within the army with a component of oneness was a standard that defined human nature which fostered a great attribute to him in providing and understanding of this phenomenon. According to him, the current young generations were aimed at providing a greater capacity than oneself which could oblige them in the aspect of duty as their most noble endeavor for the country. (http://www.maudefoundation.org/aboutTim.html) The future of the US army is to be influenced by his contributions and values in support of humanity founded on the influence of the army personnel. He had great love for his soldiers which even led to great sigh of devotion in the deepest and most genuine capacity. His long love trailed in the soldiers, the army and the whole country. In every of his action, commitment for his duty was cheerfully reflected. His death left many of his compassionate activities, contributions and values he exercised for the good of the country. His contribution as a G-1 officer remains remarkable in remembrance. He had a vision for the people in providing transformation through giving adequate standards for the persons providing human resource in the army. This is an aspect worth of emulation by others. (http://www.maudefoundation.org/aboutTim.html) He’s adequate affection and love of the people, army and country is perhaps the greatest epoch of values which the future commanders and army personnel should emulate. He serviced the cost of his roles with integrity which was occupied by his great will of revolution to provide the will and the good image of the country. According to him, his generosity in duty performance served to support the fundamental objectives allied to the G-1 occupation; well being, the force and the personnel. Generally, it was great for the Maude and the future army activity should emulate his advocacy. As a warrant officer 1 in the army the actions, values and contributions of Maude should never be evaded. At one level, his love for the country, the army, the soldiers and the families should act as an example to other warranty officers. Elsewhere, his transformation attitude for the army personnel to a better personality is a key element of emulation. Nevertheless, he had a great vow in developing the human resource capacity through a good leadership model which should also be a character and value of emulation by other personnel. Bibliography.

Cryogenics Definition and Uses

Cryogenics Definition and Uses Cryogenics is defined as the scientific study of materials and their behavior at extremely low temperatures. The word comes from the Greek cryo, which means cold, and genic, which means producing. The term is usually encountered in the context of physics, materials science, and  medicine. A scientists who studies cryogenics is called a cryogenicist. A cryogenic material may be termed a cryogen. Although cold temperatures may be reported using any temperature scale, the Kelvin and Rankine scales are most common because they are absolute scales that have positive numbers. Exactly how cold a substance has to be to be considered cryogenic is a matter of some debate by the scientific community. The U.S. National Institute of Standards and Technology (NIST) considers cryogenics to include temperatures below  Ã¢Ë†â€™180  °C (93.15 K; −292.00  °F), which is a temperature above which common refrigerants (e.g., hydrogen sulfide, freon) are gases and below which permanent gases (e.g., air, nitrogen, oxygen, neon, hydrogen, helium) are liquids. There is also a field of study called high temperature cryogenics, which involves temperatures above the boiling point of liquid nitrogen at ordinary pressure (−195.79  °C (77.36 K; −320.42  °F), up to −50  °C (223.15 K; −58.00  °F). Measuring the temperature of cryogens requires special sensors. Resistance temperature detectors (RTDs) are used to take temperature measurements as low as 30 K. Below 30 K, silicon diodes are often used. Cryogenic particle detectors are sensors that operate a few degrees above absolute zero and are used to detect photons and elementary particles. Cryogenic liquids are typically stored in devices called Dewar flasks. These are double-walled containers that have a vacuum between the walls for insulation. Dewar flasks intended for use with extremely cold liquids (e.g., liquid helium) have an additional insulating container filled with liquid nitrogen. Dewar flasks are named for their inventor, James Dewar. The flasks allow gas to escape the container to prevent pressure buildup from boiling that could lead to an explosion. Cryogenic Fluids The following fluids are most often used in cryogenics: Fluid Boiling Point (K) Helium-3 3.19 Helium-4 4.214 Hydrogen 20.27 Neon 27.09 Nitrogen 77.36 Air 78.8 Fluorine 85.24 Argon 87.24 Oxygen 90.18 Methane 111.7 Uses of Cryogenics There are several applications of cryogenics. It is used to produce cryogenic fuels for rockets, including liquid hydrogen and liquid oxygen (LOX). The strong electromagnetic fields needed for nuclear magnetic resonance (NMR) are usually produced by supercooling electromagnets with cryogens. Magnetic resonance imaging (MRI) is an application of NMR that uses liquid helium. Infrared cameras frequently require cryogenic cooling. Cryogenic freezing of food is used to transport or store large quantities of food. Liquid nitrogen is used to produce fog for special effects and even specialty cocktails and food. Freezing materials using cryogens can make them brittle enough to be broken into small pieces for recycling. Cryogenic temperatures are used to store tissue and blood specimens and to preserve experimental samples. Cryogenic cooling of superconductors may be used to increase electric power transmission for big cities. Cryogenic processing is used as part of some alloy treatments and to facilitate low temperature chemical reactions (e.g., to make statin drugs). Cryomilling is used to mill materials that may be too soft or elastic to be milled at ordinary temperatures. Cooling of molecules (down to hundreds of nano Kelvins) may be used to form exotic states of matter. The Cold Atom Laboratory (CAL) is an instrument designed for use in microgravity to form Bose Einstein condensates (around 1 pico Kelvin temperature) and test laws of quantum mechanics and other physics principles. Cryogenic Disciplines Cryogenics is a broad field that encompasses several disciplines, including: Cryonics - Cryonics is the cryopreservation of animals and humans with the goal of reviving them in the future. Cryosurgery - This is a branch of surgery in which cryogenic temperatures are used to kill unwanted or malignant tissues, such as cancer cells or moles. Cryoelectronics - This is the study of superconductivity, variable-range hopping, and other electronic phenomena at low temperature. The practical application of cryoelectronics is called cryotronics. Cryobiology - This is the study of the effects of low temperatures on organisms, including the preservation of organisms, tissue, and genetic material using cryopreservation. Cryogenics Fun Fact While cryogenics usually involves temperature below the freezing point of liquid nitrogen yet above that of absolute zero, researchers have achieved temperatures below absolute zero (so-called negative Kelvin temperatures). In 2013 Ulrich Schneider at the University of Munich (Germany) cooled gas below absolute zero, which reportedly made it hotter instead of colder! Sources Braun, S., Ronzheimer, J.
