Huck Finn and Jims Relationship free essay sample

While Huck and Jim travel down the river it becomes apparent that Jim is more of a father figure to Huck than his biological father. Pap teaches the virtues of a life not worth living, while Jim gives Huck the proper fatherly support, compassion, and knowledge for Huck to become a man. Although Huck and Jim come from separate racial backgrounds their time together allows them to surpass their ethnic segregation and become true friends, and family. While Pap acts as an anchor on Hucks heel, Jim opens up a new world for Huck, and becomes his companion and a resource of knowledge. After Huck escapes his father and the sivilized society he encounters Jim, Miss Watsons runaway slave. While on Jacksons island Jim provides useful fables and simple knowledge that aid Huck, Jims simple ideas offer a greater aid to Huck, than any that Pap had ever given.

The Count of Monte Cristo essays

The Count of Monte Cristo essays The theme of The Count of Monte Cristo, is one of vengeance, forgiveness, and power. The Count of Monte Cristo, is a story of revenge, and forgiveness all in one. This is a story of extreme revenge. The main Character Dante goes to great lengths so that he can avenge his enemies. He realizes at the end that forgiveness is the answer, and that revenge just causes tragedy. Dante is the character that embodies revenge and will change his beliefs many times. Vengeance is the overpowering theme of The Count of Monte Cristo. The story starts out with a young man Dante, he is a naive man that is in love. His life is going great until his friends betray him. He is wrongfully imprisoned for having contact with Napoleon Bonaparte. He is then taken to the Chateau dlf, a prison on an island. Dante spends 14 years there, in this time he meets Abbe Faria, who is a major influence on Dante. Abbe is the man that explains to Dante how he was imprisoned. After he tells Dante this he realizes that he has made a mistake, because now Dante wants revenge. Faria says I regret now, said he, having helped you in your late inquiries, or having given you the information I did. Why so? inquired Dants. Because it has instilled a new passion in your heart-that of vengeance. (pg. ) From this moment on Dante is starting to change from a carefree loving man to man filled with anger and vengeance. Faria was a priest and is very good at predicting human nature, al though Dante is not consumed with anger and vengeance yet he predicts that he will be. Faria helps Dante by telling him about the treasure that is hidden on an island from the Spada family. He also tells Dante how to escape. When Faria dies, Dante escapes when they throw the body sack into the sea. He then goes to look for the treasure that Faria has told him about. He realizes that with the treasure he can be a very powerful man a...

Health Law Essay Example | Topics and Well Written Essays - 750 words

Health Law - Essay Example The trained professional becomes the administrator of the hospital who is responsible to run administrative matters of the hospital. The administrator not only supervises administrative matters but also takes steps to improve the medical staff’s performance. One of the major responsibilities of an administrator is to ensure the delivery of high quality care and treatment to the patients. â€Å"Additionally, they control the day-to-day operations of the hospital, making sure patient care is being met in compliance with state standards and hospital policies† (MacKenzie, n.d.). It is also true that the administrator of a hospital is legally accountable for the quality of care being delivered to the patients. The reason is that the administrator is the main decision-making authority within a healthcare facility. All employees of a hospital, which include doctors, nurses, and paramedical staff, are required to follow the directions of the administrator. Therefore, an adminis trator is responsible for improving patient care, as well as the performance of the medical staff. Answer No: 3 I accept this statement because provision of privileges and fringe benefits to the licensed or board certified physicians depends on approval of administrators of the hospitals. All licensed or board certified physicians have the right to obtain the privileges, however, the final decision regarding provision of these rights depend on the policy set either by the administrator or by the medical chief officer of the hospital. Administrators make the policies to run different matters of the hospital. They are the bodies who decide whether they should give the right of obtaining the privileges to physicians or not. Provision of privileges to physicians is dependent on the policies and philosophy of the board of directors (Joson, 2003). They grant the privileges after analyzing the financial conditions of their organizations. Sometimes, they give this right to physicians and so metimes, they limit the provision of medical staff privileges to some specific privileges. When the administrator or chief medical officer limits the provision of privileges, physicians can choose to contact the courts, which are often employed to uphold and ensure the provision of all those privileges to the physicians that a government hospital provides to their physicians. For example, if the administration of a hospital does not provide a suitable service structure to the physicians, the physicians can contact the court to get the desired service structure. Similarly, physicians can go to court to obtain the allowances and other benefits. Summing it up, I would say that obtaining the privileges is the right of all physicians working in private hospitals and they can contact the court to obtain those privileges. Answer No: 4 In the context of medical liability, the term ‘standard of care’ refers to the level of care that the medical professionals need to provide to t heir patients. â€Å"A standard of care is a formal diagnostic and treatment process a doctor will follow for a patient with a certain set of symptoms or a specific illness† (Torrey, 2008). Medical professionals need to provide a set level of care to the patients in order to meet the standard of care. The standard of care in a hospital is same for every medical professional working in the hospital. All healthcare professionals need

Invitro Fertilization - Essay Example There is no other life experience matching the birth of a baby in importance and significance. It is usually a devastating experience when couples wishing to start a family realize that they have to contend with fertility problems. For many such couples, in vitro fertilization has been a preferred solution as it gives them hopes of having their own child (Anderson, Haimovici, Ginsburg, Schust &Wayne, 2007). The first in vitro procedure that was successful was carried out in 1977 and thousands of happy and healthy children have been born each year since then. Infertility is a couples’ inability to have a kid or become pregnant with regardless of the cause after the duration of one year of having unprotected sex using no birth control methods. Infertility affects about six million people in the United States of America which accumulates to about ten percent of men and women of reproductive age. New and advanced technologies that help women become pregnant are in vitro fertilization (IVF), gamete intrafallopian transfer, zygote intrafallopian transfer, subzonal sperm injection, partial zona dissection, embryo cryopreservation and intracytoplasmic sperm injection among others. Assisted reproductive technology is generally accepted treatment for infertile women suffering from endometriosis. Presence of an ovarian endometrial cyst works towards the reduction of the quality of oocytes. The surgical resection of endometrioma reduces the ovarian reserve for ovarian stimulation by exogenous gonadotropins. In vitro fertilization is a process whereby the ova is removed from a woman’s body, fertilized in the laboratory with her partner’s sperm and returned to her uterus with hopes of fostering pregnancy. Some practitioners use in vitro fertility combined with pre implantation genetic diagnosis as a treatment for recurring

Undergraduate - Research Proposal Example While looking at evolution of mammals, keen focus will be set on the GSD, (Genetic Sex Determination). The purpose of this research is to dig deeper into the behavior of the conserved sex determination genes in mammals. By investigating on this, findings could be used to develop an evolution pathway. This way, analysis on patterns of the mammal and birds gene development can be determined. I have decided to use an approach that investigates every sex-determination gene in the different species. Comparisons and behavior relations are observed to determine where each gene differs from each other (Haag & Doty, 3). The project will first proceed by gene collection. Types of the collected genes will go further into the different sex determination genes. For instance, while studying the genes involved in the sex determination process, the somatics will be studied different from the germ-line, focusing on the behavior of each under its classification. Study of these genes will be conducted for mammals and birds and chosen vertebrates of interest. For the vertebrates, the master genes for the sex determinants must be identified. In most of the mammals these genes are indicated in the Y-chromosomes. Alongside this, the NM accession number is to be determined and the knowledge of the longest transcript. This way a sex determining loci can be observed. A complete nucleotide has significant impact on the study of evolutionary impact of sequential pathways. DNA sequences tend to have information about the background of a certain species’ gene. Study on the rate of variations in genomes and relation to environment and population helps to draw a conclusion on the relation between the gene sequences and their evolution. So as to effectively analyze the sequence alignments for quality control, analysis of the palms would be conducted. This type of analysis enables one to determine the protein

Single Molecule Magnets and Single Chain Magnets Analysis

Single Molecule Magnets and Single Chain Magnets Analysis The structures and magnetic properties: molecular nanomagnets phenolic oxime complexes GUAN Shengyang Table of Contents (Jump to) 1 Introduction 1.1 Research background 1.2 Introduction to nanomagnets 1.2.1 Single molecule magnet 1.2.2 Single Chain magnet (magnetic nanowires) 1.3 Structure of phenolic oxime and complexes 2 Researches 2.1 Iron complex 2.2 Manganese complexes 2.3 Complex containing cobalt and sodium ions 2.4 Complex containing lanthanide 3 Conclusion 4 Bibliography Abstract The basic concepts needed to understand and model singlechain magnets will also be reviewed. 1 Introduction 1.1 Research background The researches on molecular nanomagnets began from 1990s, when the first single molecule magnet (SMM) [Mn12O12(O2CPh)16(H2O)4 was researched by Christougroup of University of Florida. [GS1]This mixed-valent manganese complex was found to have an abnormal high spin ground state of S=10[GS2] and highest blocking temperature (below which temperature could the nanomagnets show magnetic properties) in its family ([Mn12O12(O2CR)16(H2O)4], R = various). A large number of SMMs have been reported since then. These[GS3] kind of complexes display the classical property of magnetization hysteresis[GS4] and quantum properties of quantum tunnelling of the magnetization (QTM). These initial discoveries provide a molecular approach to nano-scale magnetism. Following investigation of single molecule magnets (SMMs) and single chain magnets (SCMs) explorers their potential applications in high-density information storage[GS5], quantum computing[GS6], magnetic refrigeration [GS7]and so on. However, to date, nanomagnets discovered have very low blocking temperature (TB). So it is very important to choose appropriate chelate ligands and corresponding metal centres to construct a proper complex with properties to improve blocking temperature (TB) for practical application. Phenolic oxime is a family of compounds with generic structure shown in Figure 1. The phenolate and oxime function groups could form intramolecular hydrogen bonding with its neighbour. These hydrogen bonding resulting in strong coordination effect on metal ions. Such property makes phenolic oxime a good extractant for copper[GS8] in mining industry. Detailed discussion of the phenolic oxime complex structure will be introduced in SECTION 1.3 . Figure 1 general structure of phenolic oxime In this review, knowledge of nanomagnets will be introduced firstly to provide an overview of this field. Then the structure and magnetic properties of compounds with phenolic oxime ligand will be introduced. New techniques applied in synthesis will also be included. It is hoped that this review could be used to assess the potential of phenolic oxime ligand in high performance nanomagnets. 1.2 Introduction to nanomagnets 1.2.1 Single molecule magnet It is helpful to describe the basic theory of SMM with an example. The first single molecule magnet (SMM) [Mn12O12(O2CCH3 )16(H2O) 4] 4H2O ·2CH3CO2H[GS9] was determined to have an S=10 ground spin state, which is contributed by the antiferromagnetic interactions between 4 MnIV ions and 8 MnIII ions[GS10]. However, not like normal size magnet, SMM shows slow magnetic relaxation below a characteristic blocking temperature. This phenomenon is explained by the exist of an energy barrier in reorientation process of magnetic moment. Sessoli et.al. confirmed there exists a relatively large zero-field splitting in this molecule by high-field EPR experiments with a CO2 far-infrared laser. This axial zero-field splitting leads to a splitting of the S=10 state into 21 levels: -10 , -9 , -8, -7, -6 , -5†¦0, 1, 2, 3†¦8, 9, 10. Each level is characterized by a spin projection quantum number ms, corresponding potential energy: †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ †¦..(1) D:axial zero-field splitting parameter. In [Mn12O12(O2CCH3 )16(H2O) 4] 4H2O ·2CH3CO2H D=-0.5cm-1 Figure 2 Figure 1. PovRay representation of the core of[Mn12O12(O2CCH3 )16(H2O) 4] 4H2O ·2CH3CO2H, showing the relative positions of the MnIV ions (shaded circles), MnIII ions (solid circles), and  µ3-O2 bridges (open circles[GS11]). Figure 3: Plot of potential energy of different spin state versus magnetization direction From Figure 3, it could be known that the splitting of potential energy levels resulting in a potential energy barrier in the process of changing the magnetic moment. For the example SMM, this barrier equals to E(ms=0)-E(ms=à ¢Ã¢â‚¬ Ã¢â‚¬Å¡Ã‚ ±10à ¢Ã¢â‚¬ Ã¢â‚¬Å¡)=100D. Due to the small value of D, this barrier could be easily crossed in room temperature. If sample SMM is magnetized at 1.5K, the magnetic relaxation time becomes too long to measure. When fitted into Arrhenius relationship: †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦(2) The magnetic anisotropy of the SMM is caused by the structure of the eight MnIII ions. Each MnIII ion with in octahedral crystal shows Jahn–Teller distortion. These distortion[GS12] together with spin-orbital interaction give rise to the easy axis type of magnetoanisotropy. To conclude, a typical SMM consists of an inner magnetic core with a surrounding shell of organic ligands. The desired SMM requires well isolated system which exhibit high spin ground state (S) with a high magnetic anisotropy of the easy-axis (Ising) type. The difficulty is: high spin ground state often requests for several nucleuses, but the magnetic orientation of each nuclei tends to obey Maximum Entropy Models. In this way, the highest magnetoanisotropy of a molecule couldn’t be achieved easily. Some researches show that replacing magnetic core with lanthanide[GS13] ions or using single nuclearity spincluster [GS14]could avoid this problem. Their approaches will be discussed in SECTION 2. 1.2.2 Single Chain magnet (magnetic nanowires) While clusters of SMM can be considered as zero dimensional material, it is possible that one dimensional materials such as nanowires exhibit slow magnetic relaxation and hysteresis effects which are not associated with three-dimensional (3D) order. At 1963, Glauber[GS15] predicted one dimension Ising model (easy axial) would show magnetization relaxation under low temperature. Due to insufficient knowledge in this area and stringent conditions required in the synthesis procedure, chemist wasn’t be able to find any evidences to support or against the prediction, until Gatteschi et al successfully synthesis [Co(hfac)2(NITPhOMe[GS16])] in 2001. Figure 4 Structure of NITPhOMe=4†²-methoxy-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide Figure 5 Drawing of unit cell of[Co(hfac)2(NITPhOMe)2]. Large dark spheres represent the metal ions. Hydrogen, fluorine, and most of the methyl carbon atoms have been omitted for clarity The structure of the SCM consists of Co(hfac)2 and radicals arranged in helices alternately( Figure 5). In this one dimensional structure, the magnetic core (octahedral cobalt(II) centres) has overall S=1/2 and shows easy axis of magnetization in the chain direction[SG17]. Detailed analysis of spectrums could be found in Caneschi’s report in 2001. To conclude, three essential conditions are need for design SCMs: 1) the ratio of the interaction and interactions is very large. 2) the material must behave as a 1D Ising ferro- or ferrimagnet. This requires the building block or the core of the chain have large ground state spin. 3) the interchain interactions should be minimized to avoid the magnetism of the material be associated with three-dimensional (3D) order. This final condition also apply for SMMs. 1.3 Structure of phenolic oxime and complexes Metal complexes with a planar, electronically delocalized structure have proven particularly attractive for development of cooperative electronic properties because of the strong molecule–molecule interactions that can arise from Ï€-stacking of the planar units 2 Researches 2.1 3d nanomagnet Many 3d nanomagnets have been synthesized and researched on since the first SMM was discovered. f hexanuclear MnIII SMMs based on the complex [MnIII6O2(sao)6(O2CH)2(EtOH)4](saoH2=salicylaldoxime[GS18])9-12 Spin Switching via Targeted Structural Distortion 2.2 Iron complex Variation of alkyl groups on the ligand fromt-octyl ton-propyl enabled electronic isolation of the complexes in the crystal structures of M(L1)2contrasting with Ï€-stacking interactions for M(L2)2(M = Ni, Cu). This was evidenced by a one-dimensional antiferromagnetic chain for Cu(L2)2but ideal paramagnetic behaviour for Cu(L1)2down to 1.8 K. 2.3 Complex containing cobalt and sodium ions 2.4 Complex containing lanthanide Although many magnetic transition metal complexes have been synthesised, the temperature required for transition metal complex to exhibit magnetization relaxation (i.e. blocking temperature) is too low. Hence lanthanide metals were introduced to the complex to increase the blocking temperature. 4 Bibliography [GS1]R. Sessoli, H.-L. Tsai, A.R. Schake, S. Wang,  J.B. Vincent, K. Folting, D.

Experiencing Pain Essay example -- Health, Philosophy, Personal Experi

Most would agree that pain is an emotion we want to avoid; however, experiencing pain has the potential for insight, knowledge, and a new understanding of life that may not have been in realization. Through experiencing or living with pain, a proper understanding of value can perhaps be brought to things that may not have been valued in a pain free life. Because of pain, the true meaning of life, what it is like to live, and the value of oneself and others is to be within one’s control. Pain is a destructive force, yet it can strengthen the mind and the spirit. As stated in Virginia Woolf’s essay on Being Ill, the true beauty of the people and the real beauty of the earth can be seen through the eyes of those who are in pain. Also according to Woolf, pain can lead to spiritual divinity. From my understanding, the power of prayer to some people is not in belief until pain has overtaken the body of oneself or of a loved one. Pain seems to open the eyes of those who have not correctly lived their lives. Small things in life are regularly overlooked due to the busy and determined career oriented lifestyles. The joys of life come through the detail of the small gestures given or received. The golden rule of â€Å"treat others the way you want to be treated,† is important for people who want to lead a happy life. Until he was deathly ill, Ivan Ilyich, the main character in The Death of Ivan Ilyich, never appreciated the small things in life. His focus was narrowed to one topic. â€Å"Ivan made work the center gravity of his life† (50). Before anything else, including his marriage, Ivan’s work and analyzing way of living was of first priority. Neither Ivan nor his friends valued one another. Ivan’s family and friends treated Ivan ... ...ckily, she survived and my passenger and I survived with minor injuries. Not a day goes by where I do not think about what happened, but I know it happened for a reason. Getting through this painful situation made me a stronger willed person. Taking things for granted is what I do not do. I truly value my life and my family’s lives. A life can be taken away at any second. Giving thanks for the joy and love in life is something that needs to be done daily. Material items are replaceable, but what is irreplaceable is a human being. Memories made will last a lifetime, but the physical presence of a loved one will be gone. The best advice is to live life to the fullest and value the sentimental belongings, especially family and friends. Pain is not an ease, but it helps ease the minds of those who are most important with respect and insight to value.
