Al Khwarizmi Essays

Al Khwarizmi Essays Al Khwarizmi Paper Al Khwarizmi Paper Formulas for the Future By Kyle Horn Mr. Davenport Algebra 3 9-15-10 Abu Ja’far Muhammad ibn Musa Al-khwarizmi, was a Persian mathematician, geographer, and astronomer. He was born sometime in 780 AD in Baghdad, then later died there around 850 AD. At that time the area he lived in was the epicentre of an Islamic empire which extended from the Mediterranean all the way to India. He was a scholar in the House of Wisdom in Baghdad. â€Å"The word al-Khwarizmi is pronounced in classical Arabic as Al-Khwarizmi† (bookrags) Al-khwarizmi was the author of over half a dozen astronomical books. The most remarkable was titled Al-jabr w’al muqabala , which was written around 830 AD. Al-khwarizmi did most of his research and writing in the House of Wisdom, along side other scholars. His book Al-jabr w’al muqabala is what gave the branch Al-jabr to mathematics. It is now known as algebra. â€Å"The word al-jabr is usually translated as restoring, with reference to restoring the balance in an equation by placing on one side of an equation a term that has been removed from the other. † (ms) For example 2x+2=8, the balance is restored by writing 2x=6 and then x=3. The second part of the title, al muqabala, probably meant simplification, as in the case of combining 2x+5x to obtain 7x, or by subtracting out equivalent terms from both sides of an equation†. (bookrags) In the Latin translation of al-Khwarizmis Algebra , it opens with a brief introductory statement of the positional principle for numbers and then proceeds to the solution in six short chapters of six types of quadratics: â€Å"(1) squares equal to roots, ( x2=square root of 2), (2) squares equal to numbers, ( x2 =2), (3) roots equal to numbers (square root of x = 2), (4) squares and roots equal to numbers ( ), (5) squares and umbers equal to roots ( x2+1=9), and (6) roots and numbers equal to squares ( 3x+4=x2) (members. aol. com). Chapter I covers the case of squares equal to roots, expressed in modern notation as x2+5x, x(2/3)=4x, 52+10x , giving the answers x = 5, x = 12, and x= 2 respectively. † (ms) Al-khwarizmi used the term â€Å"power† to describe a square. It is said that Al-khwarizmi describing the power of an unknown or a variable (x) designed the root as of a plant, which was the origin of the term we now use in schools and colleges. Al-khwarizmi developed the algebraic terms and condition that, after a thousand years, are still being taught in schools today. His foundation has inspired mathematicians all around the world. His book has enlightened all of us. He has impacted everything from commerce to rocket science. His studies give a way to find the unknown. Without him there is so much we would not have in this day and age. because of him we have infinite knowledge highway, or the internet. Because of him so much technology has been inspired by his works. We have the computer, ipods, tvs, cars, tractors, and airplanes. Like the Wright Brothers said, â€Å" we may have built the airplane, but math made it fly. † Who’s to say, â€Å"If Al khwarizmi hadn’t developed a system of algebra, then someone else would surely have done it. † Then again, maybe not! Maybe names like, Albert Einstein, Stephen Hawking, and Wernher Von Braun would not appear in our history books and we’d be riding horses to school and work. Many events in history have dramatically altered the paths of men and mankind, but none are any more profound than Al-khwarizmi and his insight into the practical functions and applications of algebraic formula. eb cite (history) Abu Jafar Muhammad Ibn Musa Al-Khwarizmi.

Guy De Maupassant Essay Example

Guy De Maupassant Essay Example Guy De Maupassant Essay Guy De Maupassant Essay Guy De Maupassant was a French author of the naturalistic school, who was generally considered the greatest French short story writer. During his last year of life, Maupassant suffered form mental illness. He was probably born at the Chateau de Miromensniel, Dieppe. His paternal ancestors were noble, and his maternal grandfather, Paul Le Poittevin, was Gustave Flaubets godfather. His parents separated when he was 11 years old. Maupassant grew up in his native Normandy. The gift of a photographic memory enabled him to gather a storehouse of information, which later helped him in his stories about Normandy people. Maupassant had suffered from his 20s from syphilis. The disease later caused increasing mental disorder. On January 2nd 1892, Maupassant tried to commit suicide by cutting his throat and was committed to the celebrated private asylum, of Dr Espirit Blanche at Passy in Paris, where the year after he died. I am going to write about the short story A Vendetta, in which I will explain some of the quotations to highlight the importance of horror and tension in the story. The story starts off with an important characters mother, in which she lived alone with her son in a tiny cottage on the ramparts of Bonifacio. : This is a starting scene of the story, and it tells you that she is a widow of Paolo Savrini. The writer goes into detail about the surroundings of the house, telling you that the town is built on a mountain spur. Then describes that in some places the ground is over-hanging, which gives you this ghastly feeling that the ground is going to collapse. The writer describes the sea as bristling reefs, which gives me the impression that the sea is moderately rough. Another quote is It is almost entirely enclosed by a gash in the cliff, which gives the audience a sense of closed confinement. The writer uses the word threading which gives me the impression that the sea is very choppy, and mysterious. The second paragraph starts off by describing how the houses are like nests of wild birds clinging to the rock, looking down on this dangerous channel, which tells you that the houses are right on the edge of the cliff, which sets the horror and fear to the story right into place. It makes me feel that the houses are going to fall into their watery grave at any minute. The story then continues by saying that the ships hardly venture into this part of the channel, which the writer is probably telling you that the ships might have been sunk here, and that no-one wants to venture here. The writer quotes that the wind harasses the sea remorselessly, and that gives me the idea that it is a cold, alarming sea. The writer describes patches of whitish foam around the black tips of the countless reefs, which tells me that by this description this patch of the sea is dangerously rough. The writer really describes the sea in much detail, and there is probably a reason for this. The story goes on and the writer really describes the sea a big part of the horror, tension and suspense in the story. The story changes as it stops describing the sea, and gets on with the rest of the story, by explaining the characters. The old woman in the story is a widow, and that her house is clinging to the edge of the cliff. This immediately gives me a sense of sadness for the old woman, as she has lost her loved one. I think that the old woman will have a big part in the story, as it is her house that the writer describes at the start of the story. The writer then introduces two other characters: her son, Antoine, and their dog Frisky. The dog is described as a raw-boned bitch, which tells me that the dog hardy eats anything and that you can see the dogs bones due to this. This also makes me think that the family is quite poor, as the dog is not well fed. he next part tells the audience that the dog is a sheep dog, used by Antoine as a gun-dog, which adds more tension and horror to the story, because a gun dog is used to hunt, and that means to kill an animal, so killing adds more tension and horror to the story. The story then changes from telling the audience about the characters, to actually carrying on with the story. The writer tells us that the old widows son, Antonie, was treacherously, knifed and murdered. The writer doesnt go into much detail about what happened, and doesnt go into much detail. The meaning of treacherously is deceitful and double-crossing, which means that Antoine might have double-crossed someone in order for him to be killed. The story carries on and says that a man called Nicolas Ravolati knifed him, and then escaped to Sardinia the same night. Sardinia is a boat away from Bonifacio, which meant that it was a quick and easy get away for him. I think that when it came to revenge, the widow wanted revenge instead of grieving, as she is described as motionless when the body came to her door. I think that she bottled her emotions up inside, as she refused to let anyone but her dog sty with her.

Collaborating Community Nursing and Faith Based Nursing Essay

Collaborating Community Nursing and Faith Based Nursing - Essay Example In the same way community based entities offer sensitive patient care and high quality health care to cater for the diverse health care needs in the population. The idea of faith nursing is widely referred to as parish nursing was started in 1985 and has developed immensely to date into one of the most popular forms of the nursing practice in the community setting (DeHaven, 2004). The revolutionary concept works towards incorporating healing and faith and concentrates on promotion of health within the confines of the values, beliefs and practices of the church. More importantly the concept links parishioners to the church through the provision of respect and compassion to the basics of health care. Cooperation between faith-based communities and parish nurses is beneficial to all members of society especially those that are marginalized as well as those that have not been covered by a health insurance cover (Burns and Grove, 2010). To start with this cooperation facilitates access to health care mainly to the individuals that have been isolated in society. This includes the elderly, the homeless and individuals from minority groups in the population (DeHaven, 2004). For instance, a parish nurse visited an elderly woman who was locked up and was ailing from pneumonia and found that no one had visited her or even tried to call her in a period of two months. This is a highly common occurrence especially when dealing with homebound individuals that cannot access health care. This cooperation facilitates the development of a medical schedule through the warm presence of the parish nurses. They go ahead to explain the purpose of the schedule and the anticipated results (Burns and Grove, 2010). At the end of every session recite a prayer. This is important in the overall healing process as well as patient participation (DeHaven, 2004). The current health care

6 questions - Essay Example The auditors were in the opinion that these cards needed to be reflected as unrealized sales, as the services had not yet been provided. The audit staff of the PWC affiliated audit firm disagreed with the accounting policy used for recognizing revenue related to LDI calling cards. Accordingly, the staff mentioned in its report that the profit was overstated in the financial statements by Rs280 million. No. It was a common practice worldwide and in Pakistan that the revenues were booked on the basis of sale of prepaid cards and not on their usage, therefore it meant that the audit company was not adhering to the internationally recognized standards. It was unfair to the company for the auditors to effect such sudden changes in the revenue recognition policy without any prior notice to the company management, it was improper and unprofessional. Yes. To challenge the Directives of the regulatory body such as the Security and Exchange Commission of Pakistan (SECP) as the only the commission that had the authority to appoint a new auditor in place of the former auditor removed by the company. The impact of this will be that the company would be able to successfully remove PWC as external auditors by claiming professional negligence that resulted in huge losses to the company shareholders. The company would be able to appoint a new auditor that would comply to international standards regarding the revenue recognition policy. Yes. I agree with the accusations made by the company because first and foremost the PWC audit firm did not take due international standard procedures in effecting the policy change on revenue recognition and further failing to inform the management of the company. Yes. The SECP was responsible for ensuring compliance with regulations by the listed companies. The Institute of Chartered Accountants of Pakistan (ICAP) was the

Brugada Syndrome: Sudden Cardiac Death | Literature Review

Brugada Syndrome: Sudden Cardiac Death | Literature Review BRUGADA SYNDROME: SUDDEN CARDIAC DEATH Review of Literature and Case Report. Dr. Nanda Pai Dr. Sanjeeta Umbarkar Dr. Akshay Bafna Dr. Jinal Vaghela KEYWORDS: Brugada Syndrome, sudden unexpected death syndrome (SUDS) ABSTRACT Brugada Syndrome or Sudden Unexpected Death Syndrome was first discovered by P. Brugada and J. Brugada in 19921. It is a rare genetic disorder characterised by ST segment elevation in V1 – V3 leads on ECG, ventricular fibrillation and ventricular arrhythmias which can cause sudden unexpected death in an otherwise normal patient. We wish to highlight the fact that with thorough pre-operative anaesthetic and cardiac evaluation these potentially life threatening patients can be effectively treated for minor oral surgical procedures using regional anaesthesia with lignocaine thereby avoiding general anaesthesia. INTRODUCTION â€Å"In 1992, Pedro and Josep Brugada for the first time introduced a new clinical entity with ST segment elevation in V1 – V3 leads and right bundle branch block (RBBB) pattern associated with a high incidence of ventricular tachycardia/ventricular fibrillation (VT/VF)1†. This new entity was termed Brugada Syndrome (BrS) or Sudden Unexpected Death Syndrome (SUDS), occurring in structurally healthy hearts in young individuals, causing life threatening arrhythmias and sudden death. Most of the patients are between second and fourth decades of life however â€Å"the youngest patient clinically diagnosed with the syndrome is 2 days old and the oldest is 84 years old2†. There is a male predilection, â€Å"due to the presence of more prominent I ­to channels in males than in females3† and in many countries it is the 2nd highest cause of death in younger men after vehicular accidents. Signs and symptoms include presyncopal and syncopal attacks and cardiac arrest (many a times during sleep). Routine ECG shows ST segment elevation in leads V1 – V3. Fever may precede syncope or tachycardia. There are 3 types of Brugada ECG Patterns Type 1: coved type, where ST segment elevation > 2 mm. Type 2: saddle back type, where ST segment elevation > 2mm with positive ‘T’ wave. Type 3: coved or saddle back type, where ST segment elevation Brugada Syndrome is inherited as an autosomal dominant trait. In 1998, the Syndrome was linked to mutations in SCN5A, the gene that encodes the alpha subunit for the sodium channel and since then over 300 mutations of SCN5A have been identified4. Mutations of gene SCN5A cause loss of expression of sodium channel protein which decreases the sodium current resulting in slow conduction in the heart. Bezzina et al presented evidence supporting the theory that an SCN5A promoter polymorphism, common in Asian modulates, variability in cardiac conduction and may contribute to the high prevalence of Brugada Syndrome in Asian population5. CASE REPORT A 27 year old male patient reported in the department of dentistry, with excruciating pain in lower right second molar and insisted on getting it extracted. Clinical examination and orthopantomogram revealed an extremely carious second molar. The patient was a recently diagnosed case of Brugada Syndrome (Type 3). He gave a history of chest pain about 7 years ago, however, a couple of months ago he had persistent chest pain for which he was admitted in the intensive care unit for about 10 days, during which time he had 3 presyncopal attacks. On cardiac evaluation, ECG revealed an elevated ST segment in V1 – V3 leads and partial RBBB pattern but structurally normal heart valves with normal pericardium and absence clots or vegetation. His left ventricular ejection fraction was 60%. CST (Cardiac Stress Test) was performed by Bruce protocol where patient walked for 30 minutes with 10.1 METS which showed no angina/arrhythmia. Basal ECG showed RBBB persisted throughout the test. Howe ver there were no significant ST segment changes during the test. Adequate chronotropic and ionotropic response was achieved. CST was negative for stress induced reversible ischaemia/and for arrhytmia. His family history revealed sudden death of his father at a younger age (42 years) with unknown cause. However, there was no diagnosed case of Brugada Syndrome in the family. His past surgical history revealed an appendicectomy and septoplasty. He was a chronic smoker and occasionally consumed alcohol. Since it was a minor dental surgical procedure and given the patient’s history, the tooth extraction was planned under local anaesthesia using lignocaine hydrochloride with adrenaline (1:2, 00,000) thereby avoiding general anaesthesia and the various drugs used with it that could trigger ventricular tachycardia in a BrS patient. Given the patient’s history of chest pain and diagnosis of Brugada Syndrome, patient was thoroughly evaluated by the anaesthetist and cardiologist prior to the dental treatment. High risk fitness was obtained. The patient was taken up in the intensive care unit. A ventilator and a defibrillator were kept standby. A 12 lead ECG was attached and was monitored continuously throughout the procedure. An I.V. line was secured. The anaesthetist and cardiologist along with the maxillofacial surgeons formed the surgical team. A right inferior alveolar nerve block was given using 3 ml lignocaine with adrenaline solution. Another 1 ml was used for intra-pulpal infiltration. After checking for subjective and objective signs the tooth was surgically extracted after sectioning the roots. The wound was closed using 3 – 0 vicryl. Patient tolerated the procedure well. Intra operatively patient was given 4 mg Dexamethasone along with injection Augmentin (Amoxicillin Clavulanate) 1.2 gm. Post operatively he was put on oral tablet Augmentin 625 mg and tablet Paracetamol twice a day. Patient was discharged the same day and was followed up in the dental department. DISCUSSION Brugada Syndrome is a major cause of sudden unexplained death syndrome (SUDS) and death is caused by ventricular tachycardia and fibrillation (a lethal arrhythmia) in the heart which appears with no warning. The diagnosis in Brugada Syndrome is based on the characteristic patterns on an electrocardiogram, which may be routinely precipitated by administration of certain drugs (ajmaline or flecainide). Brugada ECG pattern is very often hidden, but certain factors can unmask or trigger it like sodium channel blockers, febrile state, vagotonic agents, autonomic nervous system changes, excessive stress, tricyclic or tetracyclic antidepressants, first generation antihistamines (dimenhydrinate), a combination of glucose and insulin, hyperkalaemia, hypokalaemia, hypercalcaemia, alcohol toxicity, heavy meals at night just before sleeping, excessive vomiting, hot humid climatic conditions6. According to Nademanee and Veerakul6, north-eastern part of Thailand where SUDS is prevalent and where temperatures can soar to 41oC a study is underway to gauge the climatic influences on occurrence of SUDS and they feel that physicians should factor in temperature as a cause of arrhythmogenesis in BrS. Several drugs could precipitate ventricular tachycardia and fibrillation which are listed in world Brugada registry in http://www.brugadadrugs.org (Accessibility verified July 04, 2014). All Brugada patients and their treating physicians should be aware of these precipitating drugs at all times. Many Brugada patients are asymptomatic and the classical pattern on ECG is picked up only by an experienced and trained physician. This pattern should be correlated with age of patient, family history, chest pain, fever and presyncopal/syncopal attacks. Bupivacaine has been reported to unmask Brugada like ECG patterns when administered epidurally7. Hence we avoided bupivacaine and used lidocaine with adrenaline (1:2, 00,000 dilution) instead for our patient which was well tolerated by him. Lignocaine (class 1b antiarrythmic agent) displays rapid dissociation kinetics and produces little to no ST segment elevation in patients with congenital BrS8. The ventricular tachycardia in BrS can be prevented by avoiding certain aggravating factors like medication, drugs, fever and excessive stress. Brugada patients need to be regularly followed up over a long period of time. In severe cases the only line of treatment is placement of an implantable cardioverter defibrillator (ICD). Kloesel et al9 in 2011 did a literature search and compared results of previous reports with theirs regarding outcomes of patients with BrS who underwent surgeries and anaesthetic care and found 21 case reports and 4 case series. They collected data of 52 anaesthetics and 43 patients. In our literature search we found mention of only 2 patients of BrS who underwent surgeries in the maxillofacial region. 1) Plate fixation for mandibular fracture in 56 year old male. 2) Tooth extraction, incision and drainage of odontogenic infection in 55 year old male10. However both these patients were treated under general anaesthesia. We decided to avoid general anaesthesia thereby keeping the drugs to be used to the minimum. By thorough pre-anaesthetic evaluation, proper patient counselling, intra-operative pain control using optimum amount of lignocaine, 12 lead ECG continuously monitored at all times during procedure, constant blood pressure monitoring, avoiding use of certain drugs like bupivacaine, keeping a defibrillator standby and by having a cardiologist and anaesthetist in your surgical team these patients can be successfully managed. Post-operatively ICU monitoring is must for a minimum of 4 hours. There is a dearth of articles in the Maxillofacial and Dental literature regarding the management of these patients and we feel there is a need of more awareness of this not so rare cardiac condition among the dental and maxillofacial surgeons. With proper planning these patients with potentially life threatening and unique cardiac conditions can be safely and efficiently managed by maxillofacial surgeons for dental treatment. FUNDING None.

The Endocrine System Essay -- Biology, Hormones

In the human body we have a system that deals with chemical communication through the use of hormones, the ductless glands that secrete hormones and the target cells that respond to the hormones, this system is called the Endocrine system. This is used to help maintain the essential purpose of the human body which can range the metabolism to growth. This system also works in line with the nervous system in regulating the interior functions and keep up homeostasis and also long term behaviour. There are many hormones in the human body that can affect attitude and behaviour. A very common behaviour throughout the human life, which is affected greatly by hormones, is the sexual behaviour. There are a range of hormones which are created from the gonads and placenta which affect this behaviour. These can be set into two different categories for both male and female, male hormones is known as androgens, which has testosterone which allows the progression of the male reproductive area and the preservation, also provides secondary characteristics and behaviour. The female hormones is known as Estrogens, such as estradiol, which functions in the improvement plus preservation of the woman’s reproductive area, which allows the growth of the other sex characteristics , also the changes in behaviour and in the reproduction of the mammary glands. However both male and females, produce both types of hormones and both have important effects, but males produce more androgens and females produce more estrogens. There has been lots of attention in the connection among behaviour and hormones and it shows that the normal difference in the quantity of hormones which is presented is related with the difference in behaviour. A case of this can be... ...he affects of the female hormones as a result of it been seen as controversial to do. Therefore we have to assume that hormones affect the behaviour of all humans even though research is done on the male hormones. Although there is still knowledge in the fact that when a woman goes through her menstrual cycle that it affects their behaviour and mood, there is still no clear research into which hormones affects this change. On the other hand, females do still contain a little of the testosterone hormone in their system so this could still affect the females behaviour even though they don’t have a high amount of testosterone, however this is still yet to be researched due to complications. Overall we can see that hormones can affects one’s behaviour and there is still research yet to be done into a greater extent to find which hormones can affect which behaviour.
