Research Based Practice - Essay Example Health care providers also engage in experimental setups, which generate results and knowledge on the best means of providing health care. The findings from these experiments and the literature search are then used to make informed decisions and choices by nurses. Thus, decision-making process is based on the evidence, which is gathered from literature search and physical experiments. Health care providers also engage in questioning the decisions, which they make by evaluating the validity of the existing evidence. Such questions include â€Å"why† some methods and processes are in existences and not others. This creates foundation for the improvement of the research process in order to achieve the anticipated results of the research work. There is also partnership development at work with professional leaders. Such ensures that it is easier to disseminate and diffuse information on the best practice for the nursing. The partnerships also facilitate in end user adoption and im plementation of evidence-based

Alfalfa hay yield prediction using yield monitor data and satellite Research Paper

Alfalfa hay yield prediction using yield monitor data and satellite imagery - Research Paper Example These variables can be used as yield indicators upon which crop growth models are based (Clevers et al, 1994). Accurate yield estimation relies on the availability and quality of actual crop status data. Satellite images provide a spatial resolution in spectral bands and offer coverage cycles. A number of studies have used such satellite images for monitoring of crop development (Watz et al, 1996) a characterization of natural vegetation (Saiz et al,1996). Information about the crops can be obtained from Vegetation indices (Tucker, 1979). These are functions that measure crop reflectance in terms of spectral analysis. Studies support the fact the use of Vis from the sensors were effective in determining the spatial variation and phonological changes in vegetation, though there are several Vis defined the most commonly used VI is the NDVI(normalized difference vegetation index) (Schowengerdt,1997). Techniques to improve the use of NDVIs are being developed, for example to normalize mu lti-temporal NDVs derived from NOAA AVHRR data for atmospheric effects. (Potdar et al, 1999). The reason for the variations was the low correlation coefficients. (Groten, 1993, Sharma 1993, Rosema, 1998) The main goal of agricultural crop management is to guarantee food resource for its population. Crop yield prediction ahead of harvest time and involving large regions is important for all countries. Crop yield prediction entails the application of crop growth models and crop yield models. Despite advances in crop yield prediction models, the applicability of such a model is limited to particular crops, cultivation practices, and growing conditions (Gommes, 1998). In addition, there is recognition that an integral part of predicting yield lies in accurate identification of growing sites and measurement of crop sown area, prior to using VI based methods for predicting crop growth and yield (Gommes , 2001). Thus, the goal of our study was to validate the prediction model as per NDVI w ith actual yield. In fact, early research has revealed the need to obtain better spectral signatures for predicting growth and yield of crops (Sonia ,1999, Sonia et al ,2002). This is because no single model of prediction has proven satisfactory in all conditions. For example, models like CERES (Larrabee et al, 1985), WOFOST (Diepen et al,1989) and EPIC (Williams et al, 1984), is limited due to the fact they were targeted towards specific research methods. The leading crop simulation models have been deemed to complex for wide acceptable forecasting purposes (Gommes, 1998). Remote Sensing has been used to furnish input data for models. Spectral vegetation indices correct the atmospheric and soil spectral effects on remotely sensed data.(Broge et al,2002)(McDonald et al ,1983)(Tucker,1979)(Tucker et al, 1985)(Tucker et al, 1991)(Unganai et al, 1988)(Williams, et al, 1991). This Vegetation Index (VI) is a measure of total green biomass at any given time has been related to crop yield (Potdar et al, 1993). The normalised difference vegetation index (NDVI) can be computed from red and near infrared reflectance data available from LANDSAT-TM, SPOT, ARTEMIS, NOAA-AVHRR satellite images (Heilkema et al, 1990). The NDVI derived

Library Disaster Prepared Handbook Essay -- Library Science

According to The Library Disaster Preparedness Handbook, â€Å"the most common calamities for libraries are surely water incidences† (Morris, 1986). Water damage can occur as a result of a leaks, burst pipes, and natural disasters. Of these causes, â€Å" natural disasters of great violence are the most damaging: these include flood, hurricanes and tornadoes (Morris).† Because water damage is such a threat to a library and its collection, it is imperative libraries have disaster preparedness procedures in place for preventing or minimizing flooding and water disaster damages. The Edgecombe County School district in North Carolina learned the hard way just how important disaster preparedness planning is and just how damaging water can be when Hurricane Floyd flooded two of their schools’ libraries. Their experiences can be used as an example, and future school library programs and media specialists, like myself, can use their insights to better plan for di sasters in the future. On Wednesday, September 15 1999, Hurricane Floyd made landfall in Edgecombe County as a Category 2 storm. Because water levels were already high from Hurricane Dennis hitting the areas two weeks before, the torrential rains that accompanied Hurricane Floyd caused rivers and creeks to overflow their banks. The Edgecombe Country School District was hit hard by this flooding. â€Å"When the water ended its inexorable climb to unprecedented levels, approximately forty percent of the land area of Edgecombe County was under water† (Egerton, et al., 2000). Two of their fourteen schools were totally flooded to the extent that nothing in them was salvageable. The two schools flooded were Pattillo A+ Elementary School and Princeville Montessori School. Pattillo ... ...ican Association of School Librarians. Another great resource for public school libraries is the Beyond Words program started by Dollar General which helps replace books lost in disasters through grant assistance. It is very important that a school library have a plan in place in the event of a disaster, and have plans for all types of disasters, like floods, fire, and bombs. By planning in advance, staff will know what is expected of them during and after a disaster. It will also help keep everyone on the same page, as everything descends into chaos and uncertainty. In a school setting it is also imperative that the administration be aware of the disaster plan as well. Including the administration in the planning process will reduce miscommunication in the event of a disaster and will ensure that everyone is on the same page during each stage of cleanup.

Mariam and Laila Essay

Les miserables by Victor Hugo and A Thousand Splendid Suns by Khaled Hossieni both have tragic themes. Les miserables is a story set during 1815 in Digne, France (Hugo, 1994) about the struggles and quest for freedom of a convicted man by the name of Jean-Valijean. During the course of the story, his encounters and connection to two of the most important characters in his life – Fantine and Cosette was actually the main plot of the story. A Thousand Splendid Suns had its name through a poem entitled â€Å"KABUL. † This poem symbolizes Mariam, who is one of main characters in the story. It is a poem describing the beauty of the city of Kabul and how on the same city, a person is able to see a splendid sun each day (Hosseini, 2007). Aside from having the same themes, both stories (Les miserables and A Thousand Splendid Suns) also was able to show its readers the conflicts and the hardships that women during those times face. In Les miserables, Fantine was forced to become a â€Å"prostitute† in order to provide for her daughter (Hugo, 1994). This was because she was laid off from the factory she works for after her employers discovered that she has an illegitimate child. A thousand Splendid suns, on the other hand, shared to readers the story of young Mariam who was forced to marry, was discriminated by the society and finally was imprisoned for her honesty (Hosseini, 2007). The two stories, although written on different genres by authors of different cultures speaks of the experiences of every man and women. It talks of life in general (Jean’s search for freedom, Mariam questioning the meaning of her life, Javert’s obsession to make all offenders of the law pay and Cosette’s unconditional love for Marius). The two stories, amidst its dark tone give its readers a choice on whether to stay in the dark side of life or to eventually come out of the sun and continue living despite of all the struggles they need to overcome. The characters in both stories are unforgettable. In Les miserables, readers see a young Jean who seems to prefer being an outlaw. During the coursework of the story, readers are able to witness how the goodness in every man has won over Jeans’ weaknesses. He turns out to be the hero who saves the future of Fantine and Cosette. While on A Thousand Splendid Suns, readers are presented with two very powerful women – Mariam and Laila. Their strengths come not from physical attributes but from being able to walk through the storms of life and still stand unabashed. The difference between the two literary pieces can be seen with the way human values was depicted by the main characters. Mariam in A Thousand Splendid Suns showed readers a very important human value which is honesty. Amidst the knowledge that she can be imprisoned for her admission of accidentally killing her husband, she still surrendered herself to the authorities and accepted her fate. Jean-Valijean in Les miserables, run all his life from the responsibility of what he has done in the past. He lived a life outside the prison bars but was a prisoner of his own fears. Among the two, we can say that it was Mariam who was truly free for she has died while â€Å"paying† for her sins and thus, leaves the society without guilt in her heart. Les miserables is a literary piece with timeless life lessons. It is still popular today because it speaks of human nature in general. A Thousand Splendid Suns is also acclaimed not only because it depicts of the harshness of society’s pressures but it also reminds us that is always the truth which can set us free. There is nothing better than having to read books that not only touches the spirit and soul but also tickles every reader’s imagination. References: Hosseini, K. (2007). A Thousand Splendid Suns.

This essay and its contents is designed to define and discuss the concept of my position on the following statement: â€Å"Human activity, especially the burning of fossil fuels. It also answers inquiries of; is it a major contributor to climate change? Do I agree or disagree? From my research and readings, I‘ve concluded that, the foremost effect that burning fossil fuels has on our environment is the greenhouse effect, also known as global warming. Carbon dioxide, which is also known as greenhouse gas is released during combustion of fossil fuels and is the cause of this catastrophe. But yet, other problems arise amongst the burning of fossil fuels, for example the depletion of fossil fuels, the shift of climate control, and the†¦show more content†¦Small changes in the average temperature of the planet can translate to large and potentially dangerous shifts in climate and weather. (http://www.epa.gov/climatechange 2012) The uprising global temperatures have been supplemented by changes in weather and climate. Throughout the world, many places have seen different changes in rainfall; this crisis resulted in more floods, famines, and extreme rain, as well as additional frequent and severe heat waves. As these changes are introduced to us the coming future, they will more than likely present challenges to our society and our environment. Changes of the land Greenhouse gases act as a blanket surrounding Earth, trapping energy in the atmosphere and causing it to warm and stay warm. As we see the heating of the earth we also see the loss of ice and snow. The ice and snow cools the earth as well as reflect heat. Absorbing heat means more ice melting, which means more heat is absorbed and more ice is melted, the process is a revolving circle. Land-use change, such as deforestation, is a big contributor because trees are essentially ‘wet sticks of carbon’, and so burning them both releases CO2 and prevents the trees from absorbing CO2 through photosynthesis, their method of turning sunlight, nutrients and water into energy to grow.

The Reinforcement of Hegemonic Ideologies Gender and Sexuality Stereotypes Within Cosmopolitan Magazine Advertisements Rebecca Mastine Understanding Popular Culture Tim MacNeil December 15, 2010 Magazines have implicitly and explicitly been influencing humans for decades. They are continually more involved in the media, however the market is highly competitive. It is extremely important for magazines to maintain the readers’ interest and loyalty therefore they must excel in its appearance and content. Helen Brown created the Cosmopolitan magazine in 1965. It holds a spot as one of the most successful women’s magazines of all time, and proceeds to be the number one selling monthly magazine. (Ouellette, 360, 2005).†¦show more content†¦279).

Guidelines For Classification Of Water Hardness Essay

Water is measured in milligrams per liter or parts per million. In Table 1, the guidelines for classification of water hardness can be found. This table shows the different amounts of CaCO3, calcium carbonate, in mg/L that cause water to be soft too hard. Hardness in mg/L CaCO3 Degree of Hardness 0 – 30 Very soft 31 – 60 Soft 61 – 120 Moderately soft/ moderately hard 121 – 180 Hard 180 Very hard Table 1.4 General guidelines for classification of water hardness Two methods that are utilized in measuring the hardness of water are EDTA and AA. The EDTA, ethylene diamine tetraacetic acid, method contains 3 steps. First, preparation of a standard Ca2+ solution is needed. Second, standardization of EDTA with a standard calcium solution has to occur. The final step is an analysis of an unknown Ca2+ sample with the standardized EDTA solution (Community College of Rhode Island). During the lab, a NH3/NH4 buffer was added to the sample water to make the solution basic, a pH of around 10. EBT, eriochrome black T, was then added to this solution. The solution turned blue when EBT was added. If magnesium were present in the water, the solution would turn red. Then, EDTA, which has a known concentration, was added the red solution. The EDTA reacts with the calcium that is present in the solution bringing the solution back to its clear color. After it reacted with calcium, it will react with the magnesium turning the solution to blue. Overall, magnesium has to beShow MoreRelatedDetermination of Hardness of Water1455 Words   |  6 Pages Water â€Å"hardness† was analyzed in this experiment, through the determination of CaCO3 concentration.
