Analysis of A Sound of Thunder essays

Analysis of A Sound of Thunder essays The story A Sound of Thunder takes place in 2055 A. D. and then they go back into the past to the Jurassic Period. These people who go are expert hunters and they want to get a big catch so they intend on shooting and killing a Tyrannosaurus Rex. One of the hunters named Mr. Eckels gets scared when they see the dinosaur and went back to the machine, but he didnt stay on the path and when you step off the path you could change the past present and future of the earth. He stepped on a butterfly and killed and as a result of that, the whole spelling and the president of the United States was changed. Ray Bradburys short story A Sound of Thunder is a futuristic tale of a hunting expedition that takes place in the past during the Jurassic Period that resulted in changing the whole world and everything in it. This story was mostly about how in the future technology is going to be so high-tech that we will be able to go back in time and do things. It has more things that need to be worked out like it effecting everything in the world past, present, and future. It also focuses on how we may do one small thing, but that can change and effect many other things like the domino affect. Mr. Eckels is the person who stepped off the path and killed the butterfly. This is the act that changed the entire world when they arrived home. These hunters are going on a safari hunt that the government approved of to kill a T-Rex. The problem with this is that one of the hunters named Mr. Eckels becomes scared and turns back and steps off the path, which is a rule that they are not supposed to break because of the consequences they will face when they arrive home. When they do arrived home, Eckels figures out that the sign for the program that takes you back in time has changed. It was called Time Safari Inc. It is now Tyme Sefari Inc. He has now found out that he stepped on a butterfly and changed the pho...

Sickle Cell Anemia essays

Sickle Cell Anemia essays Sickle-cell anemia also called sickle-cell disease is a hereditary disorder affecting hemoglobin, which is the oxygen carrying substance in red blood cells. This disease ends up decreasing the ability of the hemoglobin to send oxygen throughout the body. The sickle cells begin to clog up the blood vessels which tend to cause inflammation. Sickle-cell anemia relates to me because my cousin Kenny died from this fatal disease. When he died my family greatly changed. In this research, I will explain the causes of Sickle-cell anemia. Sickle-cell anemia is a hereditary disorder in which abnormal hemoglobin, a protein found in red blood cells, causes the cells to take abnormal sickle shapes. This disease usually affects African Americans. This disease will slowly lower the ability of the hemoglobin to transport oxygen in the body. The sickle cells may block the passageways of small blood vessels which will starve the many tissues they have to give oxygen to. The hemoglobin begins to form polymers that make the red blood cells stiff and fragile. Red blood cells are rounded which allow them to easily pass through the smallest blood vessels. Sickle shaped red blood cells clump easily. It will disrupt the normal flow of the blood. This takes the oxygen away from different tissues and organs. When they begin to sickle, its mostly because they carry an abnormal form of hemoglobin called hemoglobin S. We inherit a gene from each parent. You can either get two normal hemoglobin genes (HbA), one normal hemoglobin gene (HbS), or two abnormal HbS genes. This depends on their parents genes. If a person carries one HbS and one HbA gene, they have the sickle-cell trait or are carriers and may pass it on to their siblings. When a person inherits two abnormal HbS genes from each parent, they have sickle-cell disease and will start to show symptoms. The first crises usually start in the early childhood. Crises are cr...

Recent Trends in Business Communication (Last Five Years) Research Paper

Recent Trends in Business Communication (Last Five Years) - Research Paper Example The major internal functions of business communication are information to management, information to employees, and improvement in morale. The major external functions of business communication are to make relations with the suppliers, sales of goods and services, report to owner-shareholder, report to government, and to create goodwill for the business (Kushal, 2010). Technology is shaping the mode and means of business communication around the world. Offices are adopting new methods of communication that are paperless and the distance between businesses is getting smaller with each new day. Communication in the past was characterized by writing business letters and sending memos. With the advancement in technology, business workforce interacts through teleconferencing, emails and videoconferencing (Kaur, 2010). Technology is advancing at a very fast rate and it is already changing the business communication trends. Innovations happening are geared towards dealing with the complexities of the business communications in the global economy (Scudder, 2010). Among the newest innovations in business communication is the use of electronic tools. Devices and software programs are being developed and at the same time entering the market at a significant rate. However, a lot of capital investment is required to acquire these technologies and assist the workers master them. Productivity is increased by tools such as personal digital assistants (PDAs), wikis and teleconferences. These tools also improve the way the business communicates with the customers. Use of these electronic tools may be cumbersome for the business professionals, thus, their effective use requires training, time and capital (Business-Telephone-System.org, 2010). In business communication, there are recent technological advancements that have shaped the way businesses communicate around the world. The most dominant form is the use of email and more recently the use of teleconferencing and

Reflection Using Gibbs Cycle - Development of Your Academic Learning Essay

Reflection Using Gibbs Cycle - Development of Your Academic Learning Skills and Experience in Practice During 3rd Year - Essay Example Throughout the session, I did various presentations using PowerPoint to horn my visual skills. Ethical issues were also part of communication that I learned. Numeracy was part of module seven and the activities entailed gathering and recording data, understanding research data, drug calculation, and general mathematics. The activities involved in developing IT skills in module seven were word processing, blackboard discussion, searching Databases, Emailing, and the use of the internet. Additionally, throughout the model, I developed learning skills by engaging in activities like literature search, use of literature and research, summarizing information, time management, self-evaluation, and working to deadlines. The model also helped me to know ways of working with others. I now comprehend the role of multi-disciplinary team and negotiating in teams. Feelings At first, it could not see the significance of skills in nursing. However, after meeting severally with my personal tutor, I a cknowledged the importance of skills in supporting my transition into the role of a staff nurse. Evaluation Achievement in developing communication was evident through passing the test, but I failed my oral exam due to anxiety and panic. I also did not do well in exam techniques and I will improve by meeting in groups to share knowledge and read individually for six hours. In the first attempt, I failed drug calculation but I improved by doing weekly practice. This was achieved at a 100 percent on my second attempt. To advance critical thinking skillfulness, I read more books and attended tutorial. I achieved 54 percent in research and 50 percent in the dissertation and this was a good achievement in the critical appraisal skills. How the development will supports my transition into the role of nursing (Analysis) Communication The good communication skills that I developed during the module will help me when shifting from a student to a staff nurse. The written communication profici ency will help me in my career as a nurse because I will need to write clear instructions for the patient to understand. Through the development of the communication skills, I will efficiently communicate verbally in formal and informal way. This will helps me as a staff nurse when making presentations in formal meetings and in my peer work groups. Listening skills will be an important attribute, which will help me as a nurse to assist in getting patients to value me. This is because listening will be a way of showing my interests in what the patients will say. Listening skills is always associated with humility rather than talkativeness. It can be empathetic and therefore therapeutic (Debnath, 2009, p152). Numeracy Numeracy skills will also help me in my nursing profession. The drug calculation skills that I acquired in module seven will increase my competency. Through that skill, I will not make dose errors. It is essential for nurses to be able to make accurate calculations of me dicine doses and to be fully conversant with the component of drugs in current use. Nurses should have an understanding of formulae for complex calculations. This enables them to direct the correct quantity and volume of the drugs. Incorrect drug computations can cause mistakes in prescription and harm patients. Drug computation skillfulness will therefore enable me to give right ratios, percentages, fractions and be able to interpret information found in clinical

Case studies x 2 - Essay Example The team leader should not waste much time once he realized the diversity of his team vis-Ã  -vis the group task and must make efforts to reinforce the idea of collective achievement and mutual respect. The most important task is to motivate the unmotivated and who better to do this than the thinkers? They should be used to interact with the former subgroup to listen to their views, and check if there are any systemic defects or issues that need to be resolved. These interactions give the tutees opportunities to ask questions and for the tutors to be surprised by the elements of human attitude that govern group functioning and motivation. This two-way learning process helps the group cohesion and builds a sense of belonging. In a similar manner, the team leader has to publicly acknowledge the creativity and the hard work of individuals, and explain the gains that everyone in the team would enjoy as a result of the team effort, monetary or otherwise. The role of a CEO is judged by the touchstone of a healthy growth of his organization and keeping the stakeholders happy. In order to realize his objectives, he creates his teams and treats each individual on the merits of his/her contribution to the organization in achieving the short/medium/long term goals. One of the important aspects of performance is team spirit that overcomes short term individual grouses. Comparison and discontent are universal in organizations. They are to be handled in such a way that the solution neither creates more discontent nor demoralizes. In the present case, Jim has an impeccable track record of performance. His ability to develop contacts and build networks is of considerable value to the company and at the same time, points to the respect he commands in the market. He is thus a key resource that directly generates revenues for the

Profiling Human Hair with FTIR Spectroscopy and Chemometrics

Profiling Human Hair with FTIR Spectroscopy and Chemometrics ABSTRACT Profiling of Human Hairs using FTIR Spectroscopy and Chemometrics Technique Aufa Madihah Binti Mohamad Anwar 1122204 Hair is any of the fine threadlike strands growing from the skin of humans can be found in crime scene due to interaction between victim, perpetrator and/or witness as explained in Locard’s Principle. This papers aim is to compare, categorize and identify human hair fiber using FTIR spectrometer and Chemometrics techniques. Hair samples will be collected from 200 subjects (Malay Women) of different ages groups. 50 samples will be collected from age group of people (20-30, 31-40, 41-50, >60). FTIR spectra will be obtained from each samples. The spectra of FTIR reflect the chemical and physical nature of a hair which can be classified in different group using Chemometrics techniques such as PCA (Principal Component Analysis). Keyword: FTIR, Chemometrics, Locard’s Principle, PCA Research Methodology 6.1 Materials Material uses in this experiment will be human hair. 50 strands will be collected for each group of age and the total hair strand obtained will be 200 strands: 6.2 Methods 6.2.1 Human Hair sample collection Human hair will be collected according to their age group (50 strands from each group of age). The hair fibers taken will be from telogen (fall naturally) phase and anagen (the root was cut) phase of the hair growth cycle. The hair fibers will be placed in a plastic bag and labeled accordingly. 6.3 Analysis 6.3.1 Revised IAEA Method for Cleaning Hair Fibers The cleaning process is needed to preserved hair samples for the elemental analysis. (Cargnello et al., 1995) The hair fibers will undergo ultrasonic vibration (sonicating) in each solutions for 10 minutes or less. This procedure will be done to minimize the damage of the cuticle surface. First, the hair fibers will be transferred to a small glass vial and will be covered with high purity acetone. The vial was then will be placed in Ultrasonic Disintegrator (Figure 6). The hair fibers will be sonicate of at 20 kHz for 10 minutes at the least. The acetone will be poured out and the hair will be rinsed with HPLC-grade water. These steps will be repeated again and for the last steps, the hair fibers will be rinsed and sonicated in de-ionized water inside the glass vial for 10 minutes. After all the cleaning process ended, the hair fiber will be dried under vacuum for two days before being analyzed. Figure 6 : Ultrasonic Disintegrator – Sonicater for the hair fibers 6.3.2 FTIR Spectroscopy A FTIR Spectrometer with Diamond ATR Smart Accessory (Figure 7) will be used in this procedure. The spectra of hair fibers will be recorded using the spectrometer. Figure 7: FTIR Spectrometer with Diamond Smart Accessory The parameters of FTIR-ATR for the analysis (Table 2): Before analyzing and collecting the spectrum from the hair samples, a background spectrum will be recorded. The hair fibers will then going through spectral sampling process : The fibers will be placed across the diamond crystal and will be pressed (to obtain a good contact) using the pressure tower. Spectrum will be recorded. The collected data will be saved on the Spectral Software Program (as .SPC files). Spectral Processing The recorded spectral will be saved as .SPC files and are imported into the spectral software package for spectral processing as .SPA files. First of all, the baseline of the spectra will be corrected and the offset will be set to zero. Then, the spectra will be trimmed so that it will be in the range of ÃŽ ±-keratin absorption bands which is 1759-785 cm-1 range (major characteristic of ÃŽ ±-keratin). The trimmed spectral will then be transferred to an Excel spreadsheet and saved as an .XLS file. Raw Data Matrix and Chemometric Analysis Pre-processing of data is defined as â€Å"mathematical manipulation of a data is used due to primary analysis†. (Arnberg R. et al., 1998).This step helps in eliminating or decreasing unrelated sources (systematic or random errors). Variance Scaling Scaling steps will be done prior to the fact that the treatment considers both the measurement unit of the values and the origin of scale. (Meloun M. et al., 1992) Scaling is needed to include: Cartesian system’s shift of the origin, Axes’ contraction or expansion. Double Centring Double string will be obtained by subtracting the mean of each row x (x-mean centring) and row y (y-mean centring). This procedure reduces the effect of the variance component reflected by PCI of the un-pretreated data set and removes common spectral features. (Kokot S. et al., 1997) Equation 1 and Equation 2 (Meloun M. et al., 1992) described the process above: Yim = xim – x.mEquation 1 Continued by; zim = yim yi Equation 2 Where; yim = column centred datum xim = datum in row I and column m before centring x.m = mean of column m = xim / I zim = double centred datum Standardization The standardization procedure is included to equalize the variance of each variable and to remove the weighting that is artificially imposed by the scale of the variables. (Arnberg R. et al., 1998) Standardization process can be described in the equation 3 and 4 below: yim = xim / sm Equation 3 Where; sm = (xim – x.m)2  ½ Equation 4 I – 1 = the estimate of the standard deviation of the variable, xm, about its mean. Albano et al. state that â€Å"standardization of each subset separately gives better resolution in latent variable modeling of subsets†. (Albano et al., 1981) Auto-scaling Combination of column centring and standardization is known auto-scaling. It can be represented by Equation 5 (Meloun M. et al., 1992): zim = (yim – yi) / sm Equation 5 Chemometric Analysis The doubled centred matrices will be imported into the software that cans multivariate analysis and experimental design. The processed matrices will produce the resultant PCA scores plots, loading plots and fuzzy clustering tables. Multi-criteria Decision Making (MCDM) The multivariate analysis method (PROMETHEE and GAIA) will find the relationships between the objects and variables severally. The matrix data will then undergoes packaging for decision making. Chemometrics Chemometrics helps in analysis of spectral data by solving the calibration problem. It uses statistical and mathematical methods to correlate quality parameters to analytical instrument data. The data will be observed and recorded. Then, patterns in data will be brought out and modeled. The modeled patterns will be used for data analysis in future. (Einax J.W. et al., 1997) 6.3.5.1 Principal Component Analysis (PCA) PCA is a well-known pattern recognition method for pertaining to any procedure involving multivariate (two or more variables) data analysis problems. Identification and discrimination of the objects can be obtained with the help of PCA whereby it is a data reduction technique. Data reduction technique is when the information is sorted into a data matrix using selected variables that define the columns and rows which was designated with sample measurements. PCjk = aj1xk1 + aj2xk2 + †¦ ajnxkn Equation 6 Where; PCjk = value for object k and principal component j aj1 = variable 1 on object k value xk1 = variable 1 on component j measurement n = original variables total number 6.3.5.2 SIMCA (Soft Independent Modeling of Class Analogy) Classification is defines as the process of categorizing something according to same qualities or characteristics. SIMCA is supervised method for classification of data. The method requires a training (test) data set consisting of samples where their origins are known. PCA is used to develop a model of each class within the test set. The users will select the members of a set. A model can be representing by the equation (Chatfield C., 1980): Xki = Xi + + ajiujk + eki Equation 7 Where; p = number of the principal components in the class model eki = residual value of object k on variable i Gant Chart for Research Timeline Expected Results The research regarding human scalp hair resulted in new database on human hair according to their age group for woman, Malay. With the help of chemometrics method the human hair database can be created. The data obtained from Fourier-transform Infrared Spectroscopy which was then analyze and modeled through chemometrics and the new database is set. In the database, the human hair was classified according to their age group and the composition that differs the age. Through the research, it shows that in human hair the amount of amino acid (protein) differs. As the age increase, the amounts of amino acid (protein) decrease and as the age lower the amino acid (protein) higher. 9.0 Conclusion This study is proposed to help creating a new database besides furthering investigation on human hair as physical evidence. Theory of physical evidence can be quoted from Locard’s Principal which stated that â€Å"every contact leaves a trace. Physical evidence cannot be faulty; it can’t perjure itself, and it always present. Only human failure to study, explore and understand it can diminish its worth†. Furthermore, fibers evidence is often found at the crime scene. Thus, in creating this new database it can aids in forensic process. The human hair samples that was obtained from different age group (20-30, 31-40, 41-50, >60) but same gender and race undergoes FTIR spectroscopy to detect the amount of amino acid (protein). The data was then was analyze using chemometrics. In short, it can be concluded that the amount of amino acid (protein) is inversely proportional to the age group.

Hamlet - Ophelias Identity Essay -- Shakespeare Hamlet Essays

Hamlet - Ophelia's Identity There are volumes of critical analyses devoted to William Shakespeare's Hamlet. As the title indicates, Hamlet is the main character of the play, but there are other characters who are also important to the plot. So much attention has been given to Hamlet's antics that characters such as Ophelia remain relatively unexamined. Ophelia is a key figure in the play, and to understand her reactions to the patriarchal society in which she lives through her relationships with the men in her life adds more depth to the play. Ophelia's character is revealed through her relationships with her father, Polonius, her brother, Laertes, and her lover, Hamlet, and their characters in turn are revealed through their relationships to her. The first opportunity to gain insight into tOphelia's behavior comes early in the play when her brother, Laertes, advises her to steer clear of Hamlet. He tells her that even though her body is grown her mind and emotions are not yet mature. Ophelia replies, "I shall the effect of this good lesson keep, / As watchman to my heart" but she later proves that she does not intend to follow Laertes' advice because she is still willing to be with Hamlet (1.3.47-48). In fact it is Hamlet's rejection of her that keeps her from him, not Laertes' advice. She further states, "Do not, as some ungracious pastors do, / Show me the steep and thorny way to heaven, / Whilst, like a puffed and reckless libertine, / Himself the primrose path of dalliance treads / And recks not his own rede" (1.3.49-53). Ophelia means that her brother should hold himself to the same standards he imposes on her. She also equates sexual abstinence with "the steep and thorny way" and sexual participation with... ...ed her manner of behavior. Along these same lines Hamlet has been responsible for her feelings. If he loves her, she is happy, and if he loves her not, she is not. It is through these relationships that she knows how to live, and in the absence of this knowledge and direction she commits suicide. Works Cited Berman, Allison. "We Only Find Ourselves."
