Pest Control and Waste Management Essay Example for Free

Pest Control and Waste Management Essay Pests cause a lot of destruction to the crops. Even though there are lots of chemical pest controls available to help reduce or remove the presence of these destructive pests, the non-chemical pest control is the most reliable and safest form of pest control. One of the most destructive pests that are encountered by many farmers is the beetle. Non-chemical pest control can be done in many different ways like applying balanced fertilizer to keep the crops and soil healthy and free from beetles, removing weeds from that may surround the crops, and using milky spore powder when dealing with Japanese beetles. In addition with these, according to HGTV, â€Å"planting pest-resistant species that contains insecticide in nature can also help in getting rid of these pests(Non-Chemical Pest Control, 2006). † The production of a healthy and productive crop system all depends on the supervision of the farmer itself. Nevertheless, non-chemical pest control is all about prevention. I will not be in opposition to the idea of having hazardous waste landfill, waste treatment plant, deep-injection well, or incinerator in our community. The waste of a community grows enormously as time passes by. These wastes can affect the health and livelihood of a community. The presence of hazardous waste landfill, waste treatment plant, deep-injection well, or incinerator in a certain community reduce the waste that may cause pollution and other negative effects on the residents of a certain community. The hazardous waste landfill keeps the hazardous waste from going into the soil and eventually to our body. Incineration is only an alternative to land filling. Incineration is not a very good way of waste reduction because it produces toxic air pollutants that can even cause a great problem to the health of the community. These systems are of great help in the reduction of waste although it is inevitable that wrong management of these waste management system may always lead to an unlikely consequences like the pollution that can be brought about by incineration.

Propolis and Calcium Hydroxide Against Enterococcus Faecalis

Propolis and Calcium Hydroxide Against Enterococcus Faecalis Title: An in-vitro comparison of endodontic medicaments Propolis and Calcium hydroxide alone and in combination with Ciprofloxacin and Moxifloxacin against Enterococcus faecalis. Abstract: Aim: To evaluate and compare the antimicrobial properties of Propolis and Calcium hydroxide alone and in combination with Ciprofloxacin and Moxifloxacin against Enterococcus faecalis (E. Faecalis). Materials and Methods The laboratory study was carried out to test the effectiveness of propolis and calcium hydroxidealone as well as in combination with the established endodontic medicaments (Moxifloxacin and Ciprofloxacin). The various combinations were : Group1: Propolis, Group 2: calcium hydroxide, Group 3: Moxifloxacin, Group 4: Ciprofloxacin, Group 5: Propolis + Moxifloxacin, Group 6: Propolis + Ciprofloxacin, Group 7: Calcium hydroxide + Ciprofloxacin, Group 8: Calcium hydroxide + Moxifloxacin. The efficacy of these medicaments was tested by checking for the zone of inhibition for the specific strain (ATCC 29212) of Enterococcus faecalis at different time intervals i.e. 24hr, 48hr and 72hr. Results Mean zone of inhibition was maximum in Group V (21.94Â ±4.26) followed by Group VI (18.80Â ±1.93), Group I (18.71Â ±4.26), Group VIII (15.88Â ±2.59), Group III (14.91Â ±1.00), Group VII (14.57Â ±2.17), Group IV (13.91Â ±1.00) and minimum in Group II (12.89Â ±2.14). Mean zone of inhibition were found to be maximum at 72 hr and minimum at 24 hr. At all time intervals, the combination of Propalis with Moxiflocacin showed the maximum antimicrobial efficacy. Conclusion: On the basis of the results of the present study it can be concluded that Propolis and Calcium hydroxide show synergistic effect with Moxifloxacin and Ciprofloxacin against E. Faecalis. Propolis in combination with antibiotics and alone is more effective than calcium hydroxide. Clinical significance: Since propolis alone and in combination with antibiotics was observed to be more effective than calcium hydroxide, propolis can be considered as an intra canal medicament when compared to traditional calcium hydroxide. Key words: Calcium Hydroxide, Ciprofloxacin, E. fecalis, Intra canal medicaments, Laboratory research, Moxifloxacin, Propolis. Introduction: For successful endodontic treatment, proper diagnosis, thorough chemo-mechanical preparation, and three dimensional obturation of root canal space are paramount. Regardless of these treatment protocols, bacteria can still persist in the complex anatomy of root canal space, thus the ability of intra canal medicament to restrain or eliminate residual bacteria and prevent re-infection may play an increasingly important role in achieving and maintaining a higher success rate of root canal treatment.1 The most common species recovered in over one-third of the canals of root filled teeth with persisting periapical lesion is the Enterococcus faecalis (E. Faecalis). Enterococcus faecalis is a gram positive, facultative anaerobic, coccoid bacteria. Medicaments are recommended to eliminate remaining microbes in the root canal, dentinal tubules, accessory canals, canal irregularities (such as fins, transverse anastomoses, apical deltas and other ramifications) and in the periapical/periodontal tissue to reduce periapical inflammation, encourage periapical healing, eliminate apical exudates, control inflammatory root resorption and avert contamination of the canal between appointment.2 Earlier strong intracanal antiseptics such as formacresol and camphorated parachlorophenol were used, but due to their detrimental effects on the connective tissue, their use is limited, now-a-days. The excellent biologic and antimicrobial properties of calcium hydroxide have made it the preferred choice for intracanal dressing of the infected roots canals.1 Calcium hydroxide has been added to several endodontic sealers to improve their biological properties and to augment their antibacterial activity. When used as an intracanal medicament, the most important property of calcium hydroxide is its strong antimicrobial activity. Its high pH alters the biological lipopolysaccharides in the cell walls of Gram-negative species, there by inactivating the membrane transport mechanisms.3 Propolis is a resinous product rich in flavanoid. It has been used as in a number of ways; an anticaries agent, for dentinal hypersensitivity as sealant, storage medium for avulsed tooth, for pulp capping. Propolis is ten times less cytotoxic than calcium hydroxide and has a distinguished antibacterial, antifungal, antiviral, immunomodulatry, antioxidant effect. Recent studies have reported that propolis is more effective against resistant microorganisms and is biocompatible. In endodontic procedures antibiotics can be used as an important aide but their ineffectiveness through systemic route of administration has led to the intra canal application, in order to increase their efficacy.1 Moxifloxacin and Ciprofloxacin are members of the quinolones. Among the drugs commonly used for endodontic infection, ciprofloxacin is indicated due to its efficient action against oral anaerobes, gram +ve aerobic microorganisms (Staphylococcus aureus, S. epidermidis, Sptreptococcus spp) and gram -ve enterobacteria (Escherichia coli, Enterobacter spp and Pseudomonas), which show MIC90 between 0.015 and 2 ÃŽ ¼g/mL respectively. All the species of streptococcus are sensitive to concentrations between 1.0 and 8.0 ÃŽ ¼g/mL; Other Streptococcal species like S. aureus and S. epidermidis are also sensitive to concentrations between 0.25 and 1.0 ÃŽ ¼g/mL.4,5 Ciprofloxacin has antimicrobial activity against most Gram-negative bacilli and cocci but limited activity against most Gram-positive organisms. Moxifloxacin is a new fluoroquinolone with expended spectrum of activity, including anaerobes and Gram positive organisms, especially the multi-resistant ones.3,6-10 Moxifloxacin has been found to be one of the most active antibiotics against E. faecalis with the lowest MIC50 and MIC90. From the previous literature it has been proved that ciprofloxacin to be more active other antibiotics.3,6,8,9,11 The usage of local antibiotics in endodontic treatment was advocated by Grossman in 1951. Since then numerous antibiotics have been used during endodontic treatment. The antibiotic combination has proved advantageous with the usage of triantibiotic paste.12 The laboratory study was carried out to test the effectiveness of propolis and calcium hydroxidealone as well as in combination with the established endodontic medicaments (Moxifloxacin and Ciprofloxacin). Materials and method: The study was carried out in the Department of Conservative Dentistry and Endodontics and Department of Microbiology at Saraswati Dental College and Hospital, Lucknow, India. Propolis (Hi-Tech Natural product India Ltd), Calcium Hydroxide (Vishaldentocare), Moxifloxacin (Avelox), Ciprofloxacin (Ciplox-500) were used in this study. They were distributed in different groups as presented in table no 1. The efficacy of these medicaments was tested by checking for the zone of inhibition for the specific strain (ATCC 29212) of Enterococcus faecalis at different time intervals i.e. 24hr, 48hr and 72hr. Specific stain (ATCC 29212) of Enterococcus Faecalis was procured and grown on Brain Heart Infusion Broth (BHI) under favorable temperature overnight and the growth was checked by changes in the turbidity at 24 hours. Blood Agar Media Plate was inoculated with Enterococcus faecalis (ATCC 29212) by spreading the culture over the surface of the plate with a swab. Intermittent scraping of the culture was done at different sites to make wells for the placement of experimental intracanal medicament. The experimental groups were used in their minimum inhibitory concentration (MIC) against Enterocaccus faecalis (ATCC 29212). MIC of the various antibiotics used in this study was – Propalis 340 Â µg/mL, Calcium hydroxide 2500 Â µg/mL, Moxifloxacin 2 Â µg/mL and Ciprofloxacin 8 Â µg/mL .2,13 Propolis, Calcium hydroxide and antibiotics were used as a paste in which saline acted as a vehicle. Propolis and Calcium hydroxide were mixed separately with saline on a glass slab, with the help of cement spatula, to prepare the paste. For obtaining the antibiotic paste, tablets of Ciprofloxacin and Moxifloxacin were crushed in mortar and pestle and then mixed with saline on glass slab with cement spatula. Plates were subjected to incubation at 30 Â °c for 24hrs, 48 hrs and 72 hrs (Figure 1) and the diameter of the zones of inhibition were measured in millimeters with HiAntimicrobial Inhibition Zone Scale tm C (HiMedia Laboratories Pvt Limited, Mumbai) (Figure 2). The observations were subjected to descriptive and inferential (ANOVA) statistical analysis. Results: Table 2 shows the mean zones of inhibition in different groups irrespective of time. Zones of inhibitions ranged from 10 mm (Group II) to 28 mm (Group VI). Mean zone of inhibition was maximum in Group V (21.94Â ±4.26) followed by Group VI (18.80Â ±1.93), Group I (18.71Â ±4.26),Group VIII (15.88Â ±2.59), Group III (14.91Â ±1.00), Group VII (14.57Â ±2.17), Group IV (13.91Â ±1.00) and minimum in Group II (12.89Â ±2.14). Table 3 shows the ANOVA applied in different groups. Statistically, intergroup differences were significant (p Group I ~ Group VI > Group VIII ~ Group III ~ Group VII ~ Group IV ~ Group II. Table 4 shows the mean zones of inhibition at different time intervals in different groups. Mean zone of inhibition were maximum at 72 hr and minimum at 24 hr, and the intergroup differences were significant. At all the time intervals, group V showed the maximum antimicrobial efficacy. Discussion: Intracanal medicaments are used to eliminate remnant microbial flora after a thorough chemo-mechanical preparation of root canal and hasten the healing process. Propolis which is a very effective natural product and has been a part of popular medicine since thousands of years 14, 15. The color of Propolis is dark. Made from material collected from plants by bees, It is used against pathogenic microorganisms. Due to its anti-inflammatory properties it is effective against infection, rheumatism, muscular and articular diseases, and other types of inflammation.15-17 The chemical composition of propolis varies widely. Over 200 substances have been identified in the various varieties of propolis extracted from various geographical regions, which includes phenolic acids, esters, flavonoids, alcohols, aromatic aldehydes, fatty acids, amino acids, vitamins and minerals. Special emphasis is given to the flavonoids and phenolic acids mainly responsible for its biological activity. Propolis exh ibits antimicrobial and anti-inflammatory properties, that why it has been suggested as a root canal medicament.15,18,19 Calcium hydroxide, a white, odorless powder is one of the main stay of the root canal medicaments. It has a low solubility in water, insoluble in alcohol and a high pH. The extended clinical action of calcium hydroxide is well known. It is biocompatible, and has antimicrobial and anti-inflammatory action; it also activates the alkaline phosphatase enzyme, which in turn induces mineralized tissue formation and aid in the repair process. Chemically it is classified as a strong base, and when it is associated with a suitable vehicle produces an alkaline paste. Calcium hydroxide paste dissociates into calcium and the hydroxyl ions, the resulting environment will turn alkaline because of hydroxyl ions, due to this action it is a very good root canal dressing material. For the destruction of pathogenic bacteria of root canal and dentinal tubules , these hydroxyl ions should be capable to diffuse in dentin and persist in pulp tissues in a maximum concentration to produce the pH level requir ed 15,20. Moreover various other studies reported by Molander A. and Tirali et al found CaOH to have synergistic effect with other endodontic medicaments.21,22 Ciprofloxacin, a second generation fluoroquinolone antibiotic, inhibits bacterial DNA synthesis. In dentistry, it is used as a broad spectrum antimicrobial and is effective against gram negative bacteria (staphylococcus and pseudomonas). One of the important drugs of fourth-generation syntheticfluoroquinolone is Moxifloxacin. It has superior activity against Gram+ve bacteria and anaerobes as compared to levofloxacin and ciprofloxacin.Moxifloxacin is abroad-spectrum antibioticthat is active against bothGram-positiveandGram-negativebacteria. It inhibitsDNA gyrase, enzyme which inhibit cell replication by separating bacterial DNA 12. First and second generation fluoroquinolones selectively inhibit topoisomerase II ligase domain, which leaves the two nuclease domains intact. This particular modification, coupled with the stable action of the topoisomerase II within the cell of bacteria through nucleasic activity of the intact enzyme leads to DNA fragmentation. The further generations of fluoroquinolones i.e third and fourth acts selectively for topoisomerase IV ligase domain, which makes them more effective against gram positive coverage.12,23 Antimicrobial property of propolis is due to inhibition of bacterial DNA-dependant RNA polymerases. Synergism amid antibacterial agents and propolis has been observed by Madarova L in 1980. Grange JM and Davey RW found that there was synergism between antimicrobial drugs and propolis against S. aureus particularly those which interfere with bacterial protein synthesis.24-26 Noori Al-Wahi found propalis to have synergistic properties with honey.27 Although calcium hydroxide does not bond to dentin, it does have antibacterial property. Its mechanism of actions is through the ionic break down of Ca(+) and OH(-) ions and corresponding effects on vital tissues. Protein denaturation and damage to DNA and cytoplasmic membranes are responsible for fatality of calcium hydroxide on bacterial cells .28 E fecalis appears to be highly resistant to the antimicrobial effect of calcium hydroxide. Evans et al. reported that at pH of 11.1, E. faecalis was resistant to calcium hydroxide but unable to survive at higher pH. After intracanal dressing of calcium hydroxide in radicular dentin, due to its buffering effect, the alkalinity may only reach a ph of 10.3. This one factor may be responsible to the resistance of E faecalis to Calcium hydroxide. The presence of proton pump in the cell wall of E faecalis, could be another reason for its resistance towards Calcium hydroxide.29 In the present study Propolis alone and with antibiotic was found to be more effective than calcium hydroxide and calcium hydroxide with antibiotics. Rezende Ceps R et al and Jahromi MZ et al have also found propolis to be more effective than CaOH. Propolis showed the synergistic effect with ciprofloxacin and moxifloxacin at all time intervals.13,30 In this study Propolis showed maximum efficiency against Enterococcus faecalis in combination with Moxifloxacin followed by Ciprofloxacin, which is similar to the results obtained by Krolet et al, Fernandis A et al, Ricardo Oliveria et al, Gheda Helaly et al, Kracko M et al and Stepanovic S et al who found propolis to have synergistic effect with various antibiotics.31-36 Calcium hydroxide also showed synergistic effect with antibiotic at all time intervals, which was maximum with Moxifloxacin followed by Ciprofloxacin at all time intervals. Conclusion: On the basis of the results of the present study it can be concluded that Propolis and Calcium hydroxide show synergistic effect with Moxifloxacin and Ciprofloxacin against E. Faecalis. Propolis in combination with antibiotics and alone is more effective than calcium hydroxide. The use of Moxifloxacin as an intracanal medicament should be seriously explored. In order to draw more definitive conclusions, a wider and more detailed study needs to be undertaken. Clinical significance: Since propolis alone and in combination with antibiotics was observed to be more effective than calcium hydroxide, propolis can be considered as an intracanal medicament when compared to traditional calcium hydroxide.

The Effect one’s Gender and Personality has on their Ability to Identif

Discussion This investigation aimed to explore gender differences and personality differences in the ability to identify the emotion and gender of a face. The expected results were that the response times produced by females for facial emotion and gender identification would be faster than the response times produced my males. It was also expected that participants categorised as extroverts via the Necker cube would produce faster response times when identifying the emotion and gender of a face. Although the results from this experiment were not significant, they did resemble what was expected. Concerning the first hypothesis, overall females obtained faster response times than males when identifying the emotion of a face, which also supports the findings of Hoffman (2010). A possible explanation for why this difference occurred could be due to the different developmental changes in brain functioning that occurs in males and females, thus different neuronal systems may be used when processing f acial aspects (Everhaurt et al, 2001). That is; when an emotional face is viewed different neural structures are activated in males and females, resulting in different mediation of attention to the facial cues (McClure, 2004). The results from the current study therefore suggests that females may utilise systems that are more sensitive and more efficient at picking up cues where stimulus information is limited, than males (Hall & Matsmoto, 2004). Results obtained by males in the emotion identification task emphasises previously found results by Mantagne (2005) that males are less accurate at judging emotion in a face, especially sadness. On the other hand, Rahmen et al (2004) stated that although women were faster at identifying emotion, th... ...nder and/or personality can affect their ability to identify the gender or emotion of a face. The results obtained suggest that females and extroverts are able to identify facial aspects such as gender and emotion quicker than males and introverts. This may be because neurological and environmental factors influence their ability to efficiently access appropriate strategies to extract cues during processing of a face. The study produced findings that are consistent with previous research however to produce more confident conclusions for this investigation further experimentation with more sensitive measures are required. Future studies could explore physiological changes and neural mechanisms that occur during facial identification in order to provide a deeper insight into differences between categorical groups during facial emotion and gender processing.

the bomb :: essays research papers

I read the book After the Bomb. I though this was a great book. The beginning of the book went slow. It was not very interesting. Philip is the main character. He likes to play the guitar and he likes girls. Matt, Philips, older brother is dating the girl he likes Cara. Cara is a popular girl at school. The book takes place in a town in the outskirts of Los Angeles, California.   Ã‚  Ã‚  Ã‚  Ã‚  Throughout the book Philip is trying to keep his family alive. The book starts in Philips room when he is playing his guitar. Then he goes down to dinner. The next night him and Matt go to the dance at their school. Matt is talking to a lot of girls so Cara takes Philip to dance on the dance floor. Then after the dance Philip goes home to practice his guitar and then he went to bed. The next day Matt barrows some money from Philip. That night at dinner Philip and his mother get into a very big fight.   Ã‚  Ã‚  Ã‚  Ã‚  Philip gets his guitar and goes in to the bomb shelter. Then Matt and Cara go down into the shelter to try to cheer him up. After a little while of talking they hear a very loud sudden sound. Matt opens the top of the shelters door and see’s a very bright dome shaped light. He jumps back into the shelter as fast as he could. Cara started freaking out and crying. A few minutes after the bomb stuck the earth Matt went out looking for his mother. After a while Philip starts to get very worried and goes out to check if Matt is all right. He see’s Matt trying to pick up his mother up so Philip goes and helps his brother pick up his mother and take her to the shelter.   Ã‚  Ã‚  Ã‚  Ã‚  Philips mother is very severely burnt. She has burns all over her body from head to toe. Matt starts getting radiation sickness and throughs up. Philip goes to see if he could get help. Mean while the shelter starts to get real hot inside. Then Philip returns and gets his family to go next door to take shelter in the next door neighbors house’s basement. They stay cool there until all of the fires the bomb started go out and until the air gets better. After the fire goes out Philip and Cara go to explore.

The Impotent Othello Essay -- Othello essays

The Impotent Othello Othello is one of the most extraordinary characters in all of Shakespeare's dramas. He enjoyed unheralded success on the battlefield, which gave him the reputation as one of Venice's most able generals. The Moor's military proficiency placed him in a class by himself in the same way his ethnicity distinguished him from his Venetian counterparts. These are two intrinsic and highly identifiable characteristics of Othello. But a much lesser discussed idiosyncrasy of the Moor was his sexual disorder - impotency. As striking as this claim sounds there is much evidence in the drama to support the idea that Othello was impotent in both sexual and social relationships. Othello's sexual impotence stifled the consummation of his marriage to Desdemona as the two never experienced sexual intimacy. His sexual disorder then sparked a social impotence: powerlessness in dealing with his wife and friends. In terms of shaping the final events of the drama, Othello's impotency played an even more vital role than his military might or Moorish heritage. Throughout Othello, there is much evidence to suggest that Othello and his wife Desdemona never consummated their marriage. Shortly after murdering his wife, the Moor remarked, "cold, cold my girl?/Even in thy Chastity" (V.ii.273-4). The final word Æ chastity - brings what actually transpired in their bedroom into serious question. By referring to Desdemona as chaste is it possible that Othello was divulging that he and his wife never had sexual intercourse? Other passages from the play indicate that this is indeed the case. Upon his arrival at the citadel in Cyprus, Othello invited his wife to their sleeping quarters for the second time with the following utterance: Com... ... character as his Moorish ancestry.   Ã‚         Works Cited Butler-Evans, Elliot.

Native Americans-White Relations

AP US History DBQ: Native Americans-White Relations, 1800-1850 In the time period of 1800-1850 white Americans expanded across the vast lands on the western side of the continent and regularly encountered conflict with various Indian nations. In these documents, interactions for the various Indian nations were subjected to different cultivation between each tribe per say that there were responses that filled different needs and demands. Some tribes provided benefits such as agriculture and household manufacture and produced the idea that settlements to be blended and conform into one people.Other interactions created conflict because some of our land purchases were not 100% in compliance with the constitution. Yet some Indian nations were highly influenced by leaders such as Tecumseh for which they understood his implied meanings with obedience and respect. These primary sources of information give a great insight to the goals of the whites and their encounters The businesses to furn ish clothing and subsistence to the Indians became highly insufficient however the promotion of agriculture and household manufacture were essential.The goals of the whites were to settle as uch land possible for their nation called for it with an exponentially increasing population. Acting upon a coincidence of interests these promotions will â€Å"enable them to live on much smaller portions of land, and, indeed, will render their vast forests useless† ex Doc. A. These forests found useless and disadvantageous for they are â€Å"learning to do better on less land, our increasing numbers will be calling for more land† ex Doc. A. In Ultimate concession the best possible outcome would be to â€Å"blend together, to intermix and become one people† for that we can continue xpansion without conflict.Another response of the interactions was the idea that the Indians could be granted an annuity to guarantee growth towards the cultivation of their lands. The governor w ished for the Native American populations to â€Å"become more civilized† ex Doc. B which called for grants from the government. Such examples would include an â€Å"annuity of five hundred dollars to procure the necessary articles for the purpose of enabling them to cultivate their lands† ex Doc. B. However these promotions and ideas were only a cover-up of that the â€Å"governor got them to ign a deed for their land without their knowledge†.The chiefs considerer it out of consideration to that it was not in their power to do any such thing without consent from other nations. . The Chickasaw, Cherokee, Choctaw, Creek and Seminole nations were the only 5 major tribes that were highly affected from the Indian removal acts and were forced into Indian reservations ex. Doc D. The Indians were highly influenced by Tecumseh and gave him immediate obedience and respect for he was an â€Å"uncommon genius, which spring up occasionally to produce revolutions or verturn the established order of things† ex Doc. C.Yet due to the want vs. need for land the vicinity of the United States when Tecumseh died in the Battle of Thames from American forces. Tecumseh's goal of establishing a independent Indian nation Mississippi river. In conclusion, the time period of 1800-1850 white Americans expanded across the western side of the continent encountered conflict and different interactions with various Indian nations. Popular belief believed that that to achieve an ultimate point of rest and happiness that they should share their settlements and lend together and become one people ex.Doc. A. Chiefs would be shown imaginary annuities of five hundred dollars a year only to be fooled with the signing of the deed for their lands without their knowledge ex Doc. B. One of their only leaders Tecumseh, controlled implicit obedience and respect for when he died the Indian nations would not be represented into a independent nation west of the Mississippi river e x Doc C ; D. These interactions between whites and Indians in the time period were various for the needs and demands for the Indian nations so that we would continue the westward expansion.

Peter Abelard

Peter Abelard was born in Pallet, France on April 21st 1079. His father was in a military career but Peter followed the academic path studying dialectic. Later in his teens he went to school in Paris called Notre-Dame de Paris, William of Champeaux taught him. After being taught for a while Peter began to question William and argue against him. It was William’s school where Abelard’s application of logic all began. At the young age of only twenty-two he set up his first school in Melun, he later moved his school to Corbeil, which was near Paris, for more direct competition. Soon after he moved his school his health suffered from over working. After his return he found William lecturing at a monastic retreat outside the city, and there they once again became rivals. Abelard was again victorious, and now stood supreme to William. Abelard later set up a school on the heights of Montagne Sainte-Genevieve which over looked Notre-Dame. From his successes in dialect he next turned to theology and attended some lectures of Anselm at Laon. His triumph was complete; the pupil was able to give lectures, without previous training or special study, which were acknowledged superior to those of the master. Abelard was now at the height of his fame. He stepped into the chair at Notre-Dame, being also nominated canon, about the year 1115. After this crowds of thousands of students surrounded Abelard. During all this fame he encountered romance. Living with the precincts of Notre-Dame under the care of her uncle, Fulbert, he met a girl named Heloise. Abelard soon fell in love with her. He became a tutor to this girl and he used his power for the purpose of seduction. Soon everyone seemed to know about this romance except for Fulbert and as soon as he found out they were separated. They now could only meet in secret. She soon became pregnant and at this time Abelard took her home to Brittney where she gave birth to a baby boy. Abelard proposed a secret marriage so that he did not mar his prospects of advancement in the church. Heloise opposed this idea but eventually gave in to pressure. Fulbert did not keep the secret of marriage and spread the word despite his promise to Abelard to not say anything. Fulbert then became physically and verbally abusive towards. Abelard removed her secretly from him house and took her to seek refuge in the convent of Argenteuil. Immediately Fulbert, believing that Abelard had taken her away to be rid of her plotted revenge. That night he and some others broke into Abelard’s chamber and castrated him! The priesthood and ecclesiastical office were canonically closed to him. Heloise consummated her work of self-sacrifice and became a nun. This how ever only affected his work temporarily and. After he gradually turned again to studying he reopened his school in the priory of Maisonceile. His work was effected, but only for the good, Abelard stated in the Historia, that â€Å"the hand of the lord had touched me for the express purpose of freeing me from the temptations of the flesh and the distractions of the world so that I could devote myself to learning and there by prove myself a true photosphere not of the world but of god. † He soon published all of his theological lectures and that was when his advisories discovered his rationalistic interpretation of the Trinitarian dogma. This upset many people and he was forced to burn the book and he was also held captive in the convent of St.  Medard at Soissons. He thought that this would be the worst experience that he would ever have to go through. One of the things that he did enjoy doing at convent was irritating the monks. He soon decided that life in the monastery was unbearable so he was able to go and live in a desert place until it was time for his persecution. He built himself a small cabin and he turned into a hermit. Soon after he moved to the desert students from Paris began to flock to him and he began teaching again. Fearing prosecution yet another persecution for teaching when he was not to be he found another refuge far off shore of lower Brittney. There among other thing he wrote his famous Historia Calamitatum. The pope lifted his sentence and he spent the remaining eighteen months of his life at Cluny, a sister-house of St. Marcel at Chalon, where he rested during his last sickness. The most important thing to always remember Abelard is his scholastic manner of philosphisizing. Even though he got into trouble with the church and society, still had a great impact on the medieval times and changed many lives.
