Atomic Number 5 Element Facts

Atomic Number 5 Element Facts Boron is the element that is atomic number 5 on the periodic table. It is a metalloid or semimetal that is a lustrous black solid at room temperature and pressure. Here are some interesting facts about boron. Fast Facts: Atomic Number 5 Atomic Number: 5Element Name: BoronElement Symbol: BAtomic Weight: 10.81Category: MetalloidGroup: Group 13 (Boron Group)Period: Period 2 Atomic Number 5 Element Facts Boron compounds form the basis for the classic slime recipe, which polymerizes the compound borax.The element name boron comes from the Arabic word buraq, which means white. The word was used to describe borax, one of the boron compounds known to ancient man.A boron atom has 5 protons and 5 electrons. Its average atomic mass is 10.81. Natural boron consists of a mix of two stable isotopes: boron-10 and boron-11. Eleven isotopes, with masses 7 to 17 are known.Boron exhibits properties of either metals or nonmetals, depending on the conditions.Element number 5 is present in the cell walls of all plants, so plants, as well as any animal that eats plants, contain boron. Elemental boron is non-toxic to mammals.Over a hundred minerals contain boron and it is found in several compounds, including boric acid, borax, borates, kernite, and ulexite. Yet, pure boron is extremely difficult to produce and the element abundance is only  0.001% of the Earths crust. Element atomic number 5 is rare in the solar system. In 1808, boron was partially purified by Sir Humphry Davy and also by  Joseph L. Gay-Lussac and L. J. Thà ©nard. They achieved purity of about 60%. In 1909  Ezekiel Weintraub isolated nearly pure element number 5.Boron has the highest melting point and boiling point of the metalloids.Crystalline boron is the second hardest element, following carbon. Boron is tough and heat resistant.While many elements are produced via nuclear fusion inside stars, boron is not among them. Boron appears to have been formed by nuclear fusion from cosmic ray collisions, before the solar system was formed.The amorphous phase of boron is reactive, while crystalline boron is not reactive.There is a boron-based antibiotic. It is a derivative of streptomycin and is called boromycin.Boron is used in super hard materials, magnets, nuclear reactor shielding, semiconductors, to make borosilicate glassware, in ceramics, insecticides, disinfectants, cleaners, cosmetics, and many other products. Boron is added to steel and other alloys. Because it is an excellent neutron absorber, it is used in nuclear reactor control rods. Element atomic number 5 burns with a green flame. It can be used to produce green fire and is added as a common colorant in fireworks.Boron can transmit part of infrared light.Boron forms stable covalent bonds rather than ionic bonds.At room temperature, boron is a poor electrical conductor. Its conductivity improves as it is heated.Although boron nitride is not quite as hard as diamond, it is preferred for use in high temperature equipment because it has superior thermal and chemical resistance. Boron nitride also forms nanotubes, similar to those formed by carbon. However, unlike carbon nanotubes, boron nitride tubes are electrical insulators.Boron has been identified on the surface of the Moon and Mars. The detection of both water and boron on Mars supports the possibility Mars may have been inhabitable, at least in the Gale Crater, at some point in the distant past.The average cost of pure crystalline boron was about $5 per gram in 2008.

Think Piece 1 Term Paper Example | Topics and Well Written Essays - 1000 words

Think Piece 1 - Term Paper Example There is also a difference between criminalization and decriminalization; this is due to the fact that criminalization is a form of punishment, while decriminalization is the change of a previously punishable act to a legal one, in order to save vulnerable people, for example abortion. Various acts and behaviors have been criminalized in the United States, while others have been decriminalized. Keywords: Crime, Process of Criminalization, Process of Decriminalization, Criminalization, Decriminalization, Punishment, Violation, Criminal HIV Transmission, Child Abuse, Domestic Violence, Prostitution, Abortion, Homosexuality, Gambling, Marijuana Crime can be defined as an abuse of society rules of behavior as stated and expressed by a criminal legal code (Siegel, 2009). Walston-Dunham on the other hand defined crime as â€Å"conduct in abuse of the criminal laws of a state, the government, or a local jurisdiction, for which there is no legally acceptable justification or excuse† ( 1990, p. 499). Criminalization refers to both the absolute means that place certain conduct under the threat of punishment, and to the legal action of introducing these means. Criminalization can therefore be defined as the â€Å"legally binding decision to put a certain form of conduct under the threat of punishment† (Duff, Farmer, Marshall, Renzo, & Tadros, 2010, p. 239). The difference between crime and the process of criminalization is that crime is a violation of rules that are set to govern a society, while the process of criminalization is a punishment for the law breakers. Decriminalization refers to â€Å"adjustment of moral boundaries to social change or, to retain the vocabulary borrowed from Piaget, as normative accommodation† (Abel, 1995, p. 214). Criminalization takes precedence over its counterpart decriminalization (Spierenburg, 2008). The difference between the process of criminalization and decriminalization is that in criminalization, there is a form of punishment and the acts and behaviors are regarded as illegal, while decriminalization is the change of a previously punishable act to a legal one, in order to save vulnerable people; hence in decriminalization the acts and behaviors that were regarded as illegal are no longer illegal. Examples of acts and behaviors that have been decriminalized in the United States include abortion, homosexuality, marijuana use, and gambling. Examples of acts and behaviors that have been criminalized in the United States include criminal HIV transmission, child abuse, prostitution, and domestic violence. Laws governing abortion have been varied in different states. In 1973 many states criminalized abortion. However, it was permitted when a woman`s life was at risk and many US courts stated that all abortion laws were unconstitutional. The court recognized that a woman`s right to privacy includes a right to determine whether or not to continue her pregnancy, but that right is not absolute (Marsh all Cavendish, 2009). Abortion has been the central platform for the women’s movement. Its decriminalization maintains that abortion can either be a medical or a legal issue, but a woman`s right (Anleu, 2000). Decriminalization doesn’t provide women with an absolute right to abortion, and is to be practiced by medical practitioners under critical circumstances. Homosexuality in the United States is a behavior that has been decriminaliz

Managment in Aviation Case Study Example | Topics and Well Written Essays - 2250 words

Managment in Aviation - Case Study Example But these conventional languages are flattering less common for the theoretical regulation. Every now and then even industrial dealings and employee associations are confusingly scheduled as synonyms, though these normally demote to the relationship between management and workers and the behavior of labours in corporation. The hypothetical regulation is based mostly on the supposition that workers are individuals with altering goals and needs, and as such should not be contemplation of as essential business resources, such as trucks and filing cabinets. The field takes a constructive vision of workers, supercilious that practically all wish to contribute to the enterprise productively, and that the main obstacles to their comings and goings are lack of knowledge, inadequate teaching, and failures of procedure (Armstrong, Michael, Human Resource Management Practice, 10th edition (2006). Practitioners in the field see HRM as a more innovative view of workplace management than the traditional approach. Its practices force the managers of an endeavour to express their goals with specificity so that they can be unspoken and assumed by the workforce, and to make available the resources needed for them to successfully accomplish their assignments. As such, HRM techniques, when properly practiced, are expressive of the goals and operating practices of the enterprise overall. HRM is also seen by many to have a key role in risk reduction within organisations. Synonyms such as personnel management are often used in a more restricted sense to describe activities that are necessary in the recruiting of a workforce, providing its members with payroll and benefits, and administrating their work-life needs. So if we move to actual definitions, Torrington and Hall (1987) define personnel management as being: "Those decisions and actions which concern the management of employees at all levels in the business and which are related to the implementation of strategies directed towards creating and sustaining competitive advantage"( While Miller 1987, p. 352). Academic Theory The goal of human resource management is to help an organization to convene planned goals by drawing, and preserving workers and also to administer them successfully. The keyword here possibly is "fit", i.e. HRM advancement looks for to certify a fit between the management of an organization's employees, and the overall strategic direction of the company (Miller, 1989). The essential principle of the academic theory of HRM is that humans are not equipments; therefore we need to have an interdisciplinary assessment of people in the workplace. Fields such as psychology, industrial engineering, industrial and organizational psychology, industrial relations, sociology, and critical theories: postmodernism, post-structuralism play a chief role. Many colleges and universities tender bachelor and master degrees in Human Resources

Management Planning Paper Essay Example for Free

Management Planning Paper Essay The Boeing Corporation is the world’s leading aerospace company and is the largest manufacturer of commercial jetliners as well as military aircrafts. Boeing has teams that manufacture missiles, satellites, defense systems, and communication systems. NASA turns to Boeing when they need something and Boeing operates the International Space Station. Boeing has a broad range of capabilities and skills, which is probably the reason they are the world’s leading aerospace company. With the Boeing headquarters in Chicago, more than 170,000 people in 70 different countries find themselves employed with the corporation and most of them hold a college degree (Boeing Corporation,  2012). It takes many hard working employees and managers to make Boeing a successful corporation. This paper will discuss the planning function of management, analyze the influence of legal issues, ethics, and corporate social responsibility and their effects on management planning. I will also analyze factors that influence the company’s strategic, tactical, operational, and contingency planning as they relate to the Boeing Corporation. The planning function of management is the process of setting goals within the corporation that are expected to be achieved over a set period. Therefore, Boeing got to be the world’s leading aerospace company by setting such goals. The Boeing Corporation has engineer departments, sales departments, mechanical departments, and product testing departments among a few others. Each individual department will have set goals put in place by corporate and guidelines regarding how they should achieve the desired goal for each project. Each goal is designed for each department to become the most efficient in their levels. There are six steps in management planning. The steps listed in provided course materials are situational analysis, alternative goals and plans, goal and plan evaluation, goal and plan selection, implementation, and monitor and control (Thomas S. Bateman, Scott A. Snell,  2009). Step one gathers and summarizes information that is in question. It examines current conditions with an attempt at forecasting future conditions. Step two generates alternative goals that may be used as an alternate if the first desired plan does not ork. Step three evaluates the potential of the alternative goals and prioritizes/eliminates ones that might or might not work. Step four in management planning is the selecting of goals believed to be most appropriate and feasible by the managers. Step five implements the goals and plans into action by managers. Goal achievement is likely to be linked to the organizationâ₠¬â„¢s reward system to encourage employees to achieve the goals and implement plans properly (Thomas S. Bateman, Scott A. Snell,  2009). Step six is essential in making sure goals and plans are met. If the goals and plans are not monitored and controlled managers would not know if they were ever met successfully. Boeing the huge corporation that it is has had its fair share of legal issues. The corporation has to pay special attention to detail when it concerns obeying the laws and regulations in regard the manufacturing of aircraft. The planes must be tested for safety and flying ability before they ever hit the mainstream public. Notices on the aircraft tell passengers when they should be buckled and when it is considered safe to unbuckle. Engineers have to provide manuals for the aircrafts in case any issues may arise when in use. Ethical issues come into play when Boeing makes bids to other corporations like the military or NASA. They are not allowed to charge prices that people believe to be unfair or make any changes after things have already been agreed upon. This means that the sales department has to plan how much they want to sell their product for. The main corporate social responsibility that Boeing has is safety. They have to engineer items safe for the public to be on/use. With Boeing being the world’s leading Aerospace Corporation, millions of people rely on the use of their products. That means that engineers have to know the latest safety information and managers have to make sure that they put the safety information to use. Strategic planning is used by the Boeing Corporation when making new aircraft and other items. They have to figure out how to market their item just right so that buyers will be interested in it. This planning has led Boeing to make planes more efficient and comfortable for passengers to ride on. Tactical planning is organized for competition, such as Airbus and demand for product. Boeing is a competitor of Airbus, which is another aerospace engineering corporation. Boeing has to be aware of competitor’s new products and when they will be released. This means that they have to formulate and release products either better or more efficient than the competition’s. Operational planning identifies the specific procedures and processes required at the lower-levels within an organization (Thomas S. Bateman, Scott A. Snell,  2009). So within the Boeing Corporation this would be those who deal with the delivery schedules and human resources departments. Every plane that takes off or leaves an airport has to be scheduled and the arrival/departure times displayed so that the public is aware. Human resources is responsible for the hiring/firing of Boeing’s many employees and any issues consumers may have with a product or service. If someone believes that they did not have a good experience in the flight he or she would call the resource department, and the department would most likely do everything in his or her power to make the person feel better. Contingency plans are put in place in case of any challenges that may arise when making their products. A good example of Boeing’s contingency plan is in 2008 they were trying to produce 40 aircraft a year but the United States hit an economic crisis. This meant that Boeing had to cut back their number of aircraft being created so they did not feel the effects of the economic crisis. So Boeing did not become the world’s leading aerospace corporation by doing nothing. It took hard work, planning, and management. There are six steps in management planning that corporations follow to try to ensure their survival in a competitive world. Boeing has had its fair share of legal and ethical issues and tries to abide by the rules and regulations for safety set forth by the goverment. Boeing tries to keep a strategic plan when creating new products and a tactical plan on how to market their items.

René Magritte :: essays research papers

Renà © Magritte   Ã‚  Ã‚  Ã‚  Ã‚  Renà © Magritte was born in Belgium on November 21, 1898. His childhood took place in Charlerloi. He was born to poverty and held left-wing political views. Magritte’s mother killed herself when he was only fourteen. He later joined the Communist Party. However, he preferred not to use his art for political causes.   Ã‚  Ã‚  Ã‚  Ã‚  Magritte started to create successful oil paintings in the 1920s. This is when Magritte started to come into his own. In 1922, Magritte got married to Georgette Berger. Magritte was inspired by Georgette and she became his model. He also became friendly with Victor Servranckx, who had developed a very geometric-abstract style. This was the beginning of a new direction for Magritte. In 1927 Magritte and Georgette moved to Paris to be closer to where it all happens. He started to take part in the activities of the Surrealists, which became his style of choice for the majority of his life. Magritte began combining words and images in his paintings. These word-pictures were not mere illustrations of an object or a concept. Just the opposite, his work was intended to gently destabilize our mental habits of representation. Magritte elaborated a instructive classification of this type of painting, the simplest which consisted of denying an images through words, or vice v ersa. Magritte shared the Surrealist concept of the power of desire and eroticism to change life and wanted to translate this idea through unconventional images. He continued involving metamorphosis in his work. In Black Magic, a naked woman leaning on a rock gradually merges into the blue sky. The painter was, nevertheless, distrustful of the obvious seduction of beautiful colors. In The Rape he even pushed it to the point of obsession with the features of a woman's face replaced by sexual attributes, such as breasts, a belly button and pubic hair.. In 1940, Magritte was going through a crisis resulting from the German occupation in World War II. Also, at this point Magritte’s financial situation became an issue and his dissatisfaction with his own paintings. From then on, he decided that a feeling of pleasure and an atmosphere of happiness had to predominate over the sense of anxiety. Magritte first thought about changing his iconography and began to paint the leaf-birds, which are seen in two works from 1942, Treasure Island and The Companions of Fear.

Examinations. Good or Bad? Essay

Examination is a very wide word, which is used in all spheres of life. It is the most feared word of many students. We have examinations everywhere around the world. In Singapore, students take examinations every few months and major examinations every few years. As a result, many parents often push their children to strive in examinations. This causes them to feel extremely pressured as they have to juggle extra co-curricular activities that are compulsory in Singapore’s education system as well as to ensure that they do not neglect their studies and to meet their parents’ expectations. They often end up burning the midnight oil when there are examinations, leaving them worn out. Hence, the majority of students in Singapore feel that exams should be abolished. However, examinations are also proven to be beneficial. They help observe if we were able to consolidate what we have learnt and it has given students the drive to study. Without examinations, do you think a stud ent will spend time revising? Clearly, examinations should not be abolished. Examinations have given students the drive to study. As many parents expect their children to pass with flying colours during examinations, they usually will push them to study, hoping that by doing so they will get good grades. Sending them to tuition classes or even taking time off work to help them with their studies are ways parents will push them to work hard. As many parents always tell their children, â€Å"getting good grades will get you a good job†. By doing so, students will have to put in effort into their studies and do frequent revision which helps them to understand better. Should examinations be abolished, students will not be motivated to study and do revision. Without revision, there is no point in having classes as one will not learn and remember everything being taught. Students will then laze around and waste unnecessary time which could have been used for revision which will be beneficial to them. Not only do examinations give students the drive to study, they are also used to evaluate students. It is important for schools to evaluate how well students can consolidate the material presented to them, as otherwise the teachers might have explained everything in class in vain. The evaluation based on the grades taken in exams can help the teachers see what the students’ mistakes are and what misconceptions they may have and the teacher can correct them. Moreover, it helps them to see the students’ areas of  strengths and weaknesses and ensure that the teacher is able to maintain their strengths and improve their weaknesses. Hence, students will be able to learn better and it is no doubt that examinations are helping the students. Some people point out that examinations cause a large amount of stress to many students. Admittedly, students tend to feel extremely pressured when they hear the word â€Å"examinations†. This is because they are being pressured to meet their parents’ expectations by studying extremely hard, and sometimes, even burning the midnight oil. While doing so, they also have to attend extra co-curricular activities as well as to attend ballet classes, piano classes, tuition classes, and many more. However, if students learn to manage their time properly, I do not see why they should feel stressed. By completing their homework and revision on time and by drawing out timetables, there should not be a problem when it comes to dealing with examinations. Moreover, instead of doing last-minute revision, they could have done revision every day after school. This way, they will not panic. Furthermore, if students do not waste unnecessary time lazing around and playing video games, ther e should not be a problem with not completing their revision on time. Additionally, stress helps boost brain power as well as create mental toughness, increase clarity, and it helps in greater appreciation for one’s circumstances, and contribute to a sense of confidence built on a history of overcoming of obstacles. Hence, when it comes to examinations as a whole, the good outweighs the bad. All in all, examinations have been beneficial to many people.

History of Lauropian Society

Secluded in the middle of the Atlantic Ocean, is a place called Lauropia, a wonderful society. It is always peaceful and nothing bad ever happens on the island. The island's air is always fresh and free of any toxins or pollution. Temperature on the South side of Lauropia is always warm with no humidity present. On the North side of Lauropia the weather is always perfect for winter activities, the temperature is just cold enough for the snow to fall. The North side of the island is full of steep, snow-covered mountains that are perfect for skiing. On the South side of the Lauropia clean, sandy beaches cover the land. The ocean water is crystal clear and warm. Lauropia is the perfect place to live. On the island every person would be treated as an equal. No one person would think or act like they were better than someone else. There would be no racism present, all types of people would reside here and get along together. It wouldn't matter if you were African American, Caucasian, Asian, Spanish, Mexican or any other race each and every individual would treat each other the same. Whether a person was heterosexual, homosexual, or bisexual wouldn't matter. Lauropians wouldn't judge each other by their appearance or whom they interacted with. There would be a diverse amount of different religions that would not criticize the other religions for their beliefs. Once a month all the different religions would get together at the island community building and congregate together to discuss their viewpoints and thoughts on each faith. The Lauropians would be involved in a wide variety of sports and leisure activities all year long. This would be made possible because of the extreme temperature differences on the North and South sides of the mountain. The North side would always be cold so the citizen could go skiing and snowboarding at the Lauropian Mountain Resort. The resort would offer a wide variety of different leveled slopes for the skiers on one half of the mountain. On the other half of the mountain there would be a Snowboard Park consisting of a slopes and half pipes strictly for the snowboarders. A snow tubing park would also be available for any whom has interest in snow tubing. There would family tubes and single tubes available for use. For all the snow mobilers on Lauropia, The Lauropian Mobile Park will be open for their riding enjoyment. All these activities and more on North Lauropia will have minimal charges to take advantage of the facilities. On the warm and sunny South Lauropia, the beaches will be clean and free of charge for all citizens. The beaches would have volleyball courts open to anyone. At the piers there would be docks where people could rent Jet Ski's, Speed Boats, Yachts, and Party Boats for their recreational pleasure. Sidewalks and paths would be on hand for Lauropians to roller blade, skateboard, ride bikes, and run, jog, or walk. Boating trips would also be available that take groups out in the middle of the ocean to scuba dive and snorkel. Throughout the whole island shopping centers, eateries, and sports complexes of all types will be accessible. Any store imaginable would exist for the Lauropians to shop for their wants and needs. The women would be in shopping heaven with the amount and variety of stores available to them. The amounts of places to eat would be incredible. They would range from places like Burger King and McDonalds, to Chi Chi's and Lone Star, to five star restaurants. Any type of food that a person had a craving for would be accessible. Sports Complexes would be placed all over the island for Lauropians to participate in any athletic event that they enjoyed. There would be football, baseball, field hockey, softball, soccer, and lacrosse fields. Indoor and outdoor courts for tennis players would be accessible. If there were any sports that a person or group of people would want to play and the facilities were not available the Lauropian Sports Board would do their best to make them available. The Lauropian Society would always try to make the island enjoyable for each person. Schooling would be one of the most important aspects of life on the island. It will be required for all citizens to start their education at elementary school level and continue up to collegiate level. It would not be required, but if the parents wanted to start sending their children to nursery or preschool the facilities would be open for use free of charge. All schooling on the island would be free of charge because education is of great importance to the people of Lauropia. The schools would administer the best education possible. There would be a large variety colleges available for students to choose from depending on their individual or dual major. If a person decided that they did not want to finish their schooling, being banished from the island would punish them. When and if the person decides they want to come back to island to finish their education the school board will have a meeting and decide if that certain person deserves to be let back on the island. On most occasions the student will be allowed to come back. Once a person graduates from college and gets a job, if they decide they want to go back to college to further their education, the company that they work for will usually give them funding for it. Students will be required to go to school for nine months out of the year. Altogether students would be required to attend seventeen years of schooling. In order to insure that the students would be getting an excellent education the teachers would have to take a Teaching Exam every five years. If the teachers fail to complete the requirements and the written section of the test they will not be permitted to teach for one year. After the period of time is up the teacher may retake the test and if he or she passes it, they will then be allowed to teach again. Teachers would also be required to go back to college annually and take two courses to broaden their knowledge. All measures would be taken that would be necessary to maintain the finest quality of education for Lauropians. The citizens of Lauropia would be able to make up their own laws and rules. Each year the members the government would sit down and revise the laws from the years before if necessary. Each community on Lauropia would have representatives that would go around and take ideas and thoughts on how the island could be changed and run to make it better place to live. Laws would never be passed if a large number of people on the island disagreed with them. The main concern that the government would have is the Lauropians happiness.

The Use of Death In Beowulf essays

The Use of Death In Beowulf essays In the story of Beowolf, the three main themes of fate, courage, and death stick out. Death mostly sticks out towards the end of the story in the chapter about Beowolfs death after his fight with the dragon, but also sticks out in other parts of the story. You could say death was the whole reason that most of the story happened. It all started back when Abel was killed by Cain. Cains offspring together produced a slime from which Grendel was born. Since Grendel was naturally evil, he killed nearly 30 men at the beginning of the story just because he enjoyed eating them. Grendels murdering went on for years to come until Beowolf heard of it. Beowolf made the journey to the kingdom and took on Grendel in the first big fight of the story, which ended up in the monsters demise. Grendels Mother then heard of her sons death resulting in her being bent on revenge. She tried to take on Beowolf herself, but she ended up dying at his hands also. In the final few chapters of the story, Beowolf dies after his battle with the dragon.

Installing MySQL on a Mac Is Easier Than You Think

Installing MySQL on a Mac Is Easier Than You Think Oracles MySQL is a popular open-source relational database management system that is based on Structured Query Language (SQL). It is frequently  used in conjunction with PHP to enhance the capabilities of websites. PHP comes preloaded onto Mac computers, but MySQL does not. When you create and test software or websites that require a MySQL database, it is handy to have MySQL installed on your computer. Installing MySQL on a Mac is easier than you might expect, particularly if you use the native installation package instead of the TAR package, which requires access and changes to the command line in Terminal mode. Installing MySQL Using the Native Installation Package The free download for the Mac is the MySQL Community Server edition. Go to the MySQL website  and download the latest version of MySQL for MacOS.  Select the native package DMG archive version, not the compressed TAR version.Click the Download button next to the version you choose.You  are prompted to sign up for an Oracle Web Account, but unless you want one, click No thanks, just start my download.In your downloads folder, find and double-click the file icon to mount the .dmg archive, which contains the installer.Double-click the icon for the MySQL package installer.Read the opening dialog screen and click Continue to begin the installation.Read the license terms. Click Continue and then Agree to continue.Click Install.  Record the temporary password that displays during the installation process. This password cannot be recovered. You must save it. After you log in to MySQL, you are prompted to create a new password.Press Close on the Summary screen to complete the installation. The MySQL webpage contains documentation, instructions and change history for the software.   How to Start My SQL on a Mac The MySQL server is installed on the Mac, but it does not load by default. Start MySQL by clicking Start using the MySQL Preference Pane, which was installed during the default installation. You can configure MySQL to automatically start when you turn on your computer using the MySQL Preference Pane.

Hormonal Therapy after Menopause Medications Research Paper

Hormonal Therapy after Menopause Medications - Research Paper Example Synthetic estrogen and progesterone (or sometimes just the estrogen) are administered in small doses in order to relieve or alleviate symptoms, especially hot flushes (Pathy et al., 2012). However, sufficient medical history is needed before administering HT to menopausal women. A complete physical exam, pap smear, mammography, examination of hormonal levels, cholesterol levels, vitamin D levels and bone density scans, as well as the presence or absence of sexually-transmitted diseases are measured before giving it out to those who suffer from menopausal symptoms (Hawkins, Roberto-Nichols, & Stanley-Haney, 2012). Symptoms of menopause include loss of elasticity of the vagina and the decrease in blood circulation as well as fatty tissue which results in dryness and itchiness, pain around the urethra, hot flushes and night sweats, as well as decrease in bone density that leads to osteoporosis for some women (Hawkins et al., 2012). Other observed symptoms include dementia and cognitive impairment among older women, as well as cardiovascular diseases due to the loss of elasticity of the blood vessels due to the decrease in the release of estrogen and progesterone in the bloodstream (Pathy et al., 2012). Another likely symptom of menopause is depression, which is also due to the low estrogen levels that circulate in the blood. Alongside HT, anti-depressant drugs are also administered routinely to women by physicians not only to women who naturally entered menopause but also to women who had a hysterectomy, or â€Å"surgical menopause† (Stoppard, 2000). For this report, a study by Zanardi, Rossini, Magri, Malaguti, Colombo and Smeraldi in 2006 about assessing the response to anti-depressants of post-menopausal women undergoing HT as well as those who are not, as well as the possible effects and influence of these anti-depressants to the hormonal levels of these women. Background of the Study The study by Zanardi et al. (2006) aims to evaluate the response of p ost-menopausal women to selective serotonin reuptake inhibitors (SSRI’s) and documenting the interactions of SSRI’s with sexual hormones in women undergoing and not undergoing HT. Due to few documentations of post-menopausal women under risk of undergoing depressive episodes, the scant amount of studies concerning the influence of HT in reaction to anti-depressants which end up in ambiguous and bias results, few or incomplete basal assessment of hormonal levels before HT, as well as a lack of studies with a considerable sample size, this study was conceptualized in order to find out if the use of HT would be able to improve the effects of SSRI’s in post-menopausal women. Also, proving the synergistic action between anti-depressants and hormonal therapy could give hope for women who suffer menopause and depression, as well as their healthcare providers in managing their symptoms. This study is also significant especially to people who specialize in geriatrics, in order for them to be able to assess as well as address the needs of their female patients undergoing menopause, depression or both. Methods of the Study Roughly 200 patients of the Research Center for Mood Disorders in San Raffaele Hospital, Milan were chosen for this study. Women above 40 years of age, has amenorrhea for least 12 months and were suffering from a major depressive episode were chosen for this study. Those who were excluded were women who had a history of drug or alcohol abuse, anorexia, other
