Mycobacterium tuberculosis - Essay Example Particles that are 1-5 mm in size might be saved airborne for delayed periods, and when breathed in by a helpless individual, the bead navigates through the nasal sections, towards the lung alveoli where they are inundated by macrophages and circulated all through the body. The microorganisms may stay lethargic yet at the same time suitable for a long time (this is called idle TB contamination). Individuals with inactive TB disease are not irresistible, however have 10% possibility of building up a functioning TB contamination sometime down the road. People who have poor invulnerable frameworks or who have different disorders have higher dangers of being effectively contaminated; for instance, people with HIV have the most elevated danger of getting TB (Gandhi, et al., 2006). Co-contamination with different maladies expands the trouble in rewarding the tuberculosis. A TB understanding that has high odds of improving transmission has the accompanying qualities: a) lung ailment; b) has hack; c) positive for nearness of corrosive quick bacilli (AFB) in the sputum; d) doesn't cover mouth and nose when hacking or wheezing; e) has chest cavitations as seen in the chest radiograph or X-beam; f) and didn't complete the entire range hostile to TB medicate treatment (Centers for Disease Control and Prevention, 2005). The probability of transmitting TB to others is upgraded in generally little, encased spaces with deficient neighborhood ventilation that doesn't guarantee the expulsion of the air beads containing the bacterium. M. tuberculosis without anyone else doesn't cause hurt since it doesn't create any poison. Anyway it can consistently develop and increment in number in the body. It appends to surfaces in the lungs and produces stores called tubercles. The tubercles cause irritation and parasitically drain the dietary prerequisites of the host bringing about what is known as the state of â€Å"consumption†. This condition brings about misfortune in hunger, g enerally speaking shortcoming and hacking as more tubercles are shaped in the patient. Tuberculosis is a worldwide issue; in 2006, the illness executed 1.7 million individuals and is the primary driver of passings in individuals with HIV/AIDS (World Health Organization, 2009). 8,000,000 individuals around the world, and in the US, 1 out of 14,801 or 0.01% of the populace are effectively tainted. The World Health Organization assesses that 33% of the world’s populace harbor the TB bacterium, with capability of getting effectively contaminated. Tuberculosis can likewise be transmitted from people who have the bacterium however are not being treated for TB, or from people with TB, yet are unconscious that they have it. Irresistibleness of people likewise differ; a few patients are rarely irresistible, while those that are unconscious that they have TB and are not getting treatment could be irresistible for drawn out periods (Centers for Disease Control and Prevention, 1994). Sid e effects of TB are industrious hack, bleeding sputum, weight reduction, night sweats and fever. Tests for TB are accessible and ought to be performed if an individual is believed to be tainted particularly in nations or areas where TB is pervasive. To analyze TB, chest radiography (or X-beams), skin tests, and sputum microscopy and culture are performed. These tests might be important to make a conclusion. The purged protein subordinate (PPD)- tuberculin skin test is the main known test that can distinguish the contamination of Mycobacterium tuberculosis, however care ought to be given in deciphering the outcomes. Chest x-beams are reminiscent of TB if cavitation

purchase custom The Sun Recorded Through History article The warmth vitality is provided to a liquid, which is warmed until it disintegrates; the fume is then packed at high weight, and discharged at high strain to offer movement to a gas turbine that is coupled to a generator. At the point when the turbine is set into movement by pressurized gas or water fume it pivots the pole associated with the generator, which thusly turns the pole associated with the curl of the generator offering movement to the loop of the generator. A generator is a machine or a gadget, which changes over mechanical vitality to power. The mechanical vitality that is changed over to electrical vitality can be acquired from atomic and substance vitality found in different kinds of fuel, it can likewise be gotten from sources, for example, falling water or wind. This mechanical vitality can be provided to the generator utilizing water or wind turbines, electric engines, gas ignition turbines, inward burning motors and steam motors. The working guideline of a generator depends on the electromagnetic acceptance marvel. The generator has a conductor that is set between two magnets; the development of the conductor comparative with the attractive field made by the two magnets actuates a voltage in the conductor. On the off chance that there is an outside circuit associated with the conductor, the voltage prompted in the conductor would make a current in the circuit, and the vitality in this circuit can be conveyed to a heap. To get a bigger current from the conductor, a huge power must be applied to turn the conductor and keep it moving. Most present day generators have self energized fields; this implies the current in the field loops originates from the extra energizing twisting found in the armature. Before the voltage is taken care of in the field loops, it is corrected by going it through a diode connect, at that point goes through a controller. A segment of current that is created by the generator streams into the field curl producing an attractive field. Notwithstanding, before the generator is begun the attractive field is produced utilizing the remaining attraction in the centers of the magnets or a current from a battery. Biofuels, which incorporate ethanol or biodiesel, are known as fluid daylight. Ethanol is delivered utilizing plants to change over sunlight based vitality into a fluid that is utilized as a wellspring of vitality in transportation framework. Plants catch the suns vitality through the procedure of photosynthesis, and afterward change the vitality to cellulose, sugars and starches (Nelson standard 8). Ethanol is later fabricated utilizing different mechanical procedures by consolidating water with plant material with an expansion of vitality; the procedures produce ethanol and results, which incorporate dirtied water. The resultant item, which is ethanol, is then utilized in transportation frameworks. The present procedures of creating ethanol from daylight are viewed as including and exorbitant. The necessary crude materials is from biomass, for the most part from sugarcane and corn among other vitality harvests, and this vitality crops must be developed widely for huge scope creation; this has a tremendous financial ramifications and makes rivalry for land with the food crops. Innovation of changing over daylight into fuel has taken another course so as to take care of the issue of rivalry for land with for food crops, and lessen the expense of creation. The most recent innovation utilizes bacterium that is hereditarily adjusted to change over daylight, carbon dioxide and water to fuel; this innovation is relied upon to create more fuel than that delivered by ethanol (Nelson par16). At the point when 1litre of ethanol is singed, it produces 23.5 million joules. Streams are common frameworks that give falling water or streaming water that sets a generator into movement. The falling or streaming water is a direct result of the water cycle brought about by daylight, when the daylight warms the earth surface, it causes dissipation of water from the earth surface, this water as fume ascends the earth surface, and when it arrives at the high districts over the earth surface, it consolidates, and later falls as downpour. The downpour water permeates through the dirt and shakes, and gathers in channels shaping waterways. The water in the streams and if a generator is set in its way, it gives the generator a movement, if the water in the waterway experiences a precarious stone it makes a cascade, and when a generator is set beneath the cascade, the falling water gives the generator a movement. This vitality from falling or streaming water offers movement to the generator, and it is considered eventually from the sun in light of the fact that without the sun, the water on the earth surface would not dissipate, consolidate and fall as downpour that later gathers to shape waterways that stream. The ice that structures on mountains likewise melts to frame water that streams down the mountain to join the waterways that streams offering movement to the generator; without daylight, the ice on mountains would not liquefy to water, and there could be no water streaming in waterways to offer movement to the generator. The measure of vitality that arrives at the top air is 1,360 watts for every square meter, and the sum showing up at the earth is 340 watt for each every square meter. This is just one fourth of the sun based irradiance; it is additionally the normal measure of vitality that contacts a people rooftop for each square meter. In any case, the specific sum arriving at ones rooftop in a day relies upon the area of the house on the earth surface, the season and time. At the point when one needs to utilize the 340 watt vitality for every square meter and the day by day utilization of 14,400 watts for each day, at that point a 26 square sun based board is required, which cost nearly $16,000, and since daylight isn't steady an inverter is required, which builds the expense of establishment further. Taking a gander at the yearly power charge, it adds up to $91, it is smarter to utilize power from the principle than pay for such cash for establishment. The restitution time frame for such a vita lity framework is long, and thinking about the low productivity of sunlight based force frameworks, it isn't commendable putting resources into them; this is the reason numerous individuals timid from utilizing these frameworks. Sun based cells are utilized in satellites, mini-computer and sun oriented force creation frameworks; they are likewise alluded to as photovoltaic cells. Photovoltaic cells are developed utilizing semiconductor materials, for example, silicon; these cells convert daylight straight into power. At the point when the suns light strikes the sun powered cell, some portion of it is caught up in the semiconductor material, and thumps the electros in the structure making them allowed to stream. The electric field in the semiconductor material at that point powers the free electrons to stream a specific way, and as the electrons stream they make an electric flow. Silicon, a material used to make the sun based cell havespecial properties, particularly when it is in crystalline structure, it has 14 electrons in its three shells, the first and second shells have two and eight electrons separately. The third hellfire has just four electrons, this implies this level is half full, consequently, it will consistently look for how to occupy the rest of the space for four electrons. Silicon will be compelled to impart electrons to the particles encompassing it, framing an unadulterated crystalline structure; this structure doesn't promptly onduct power since it has no free electrons (Martnez 321). Subsequently, the structure is blended in with iotas with free electrons, for example, phosphorus to make it direct power. At the point when the daylight strikes this structure, it powers the electrons to break free, and every electron deserts a gap and searches for another electron to possess; this makes the electrons move arbitrarily in the crystalline cros s section, and as they move, the convey ebb and flow. The exhibition of a PV cell relies upon conditions, for example, the sort of PV cells, sun based ghostly, point of occurrence, sunlight based irradiance and the temperature. Roughly 90% of sun based boards utilized today are made of crystalline silicon; they convert 15-20% of the daylight to power (Martnez 346). There are sun oriented cells that have a slight film of crystalline silicon, this kind of sun oriented cells changes over 4-10% of daylight arriving at it. The sun oriented cell delivers a DC current, which can be utilized to control DC gadgets, nonetheless, for frameworks that are intended to control AC machines or apparatuses, an inverter is incorporated to change the DC current to AC. A fridge is a framework that moves heat from an area of low-vitality to a locale of high-vitality repository. This framework comprises of the accompanying parts, the cooling curl, evaporator, condenser, blower, condenser siphon, cooling tower, cooling tower fan. The refrigerant assimilates heat from the chiller or cooler chamber, at that point moves dissipates in the evaporator and sucked by the blower and released outside the fridge. The cool uses the working guideline like that of a fridge, in any case, the thing that matters is that the climate control system cools a greater space when it is contrasted with the cooler; it can cool a whole room, while a cooler cools just a chiller or cooler. The climate control system comprises of a blower, condenser and evaporator; the working liquid experiences the blower at while it is cool and at a low weight, it is then compacted and gone to the condenser at a high weight, at that point went to the evaporator where it changes from fluid to fume, as it cools the room (OECD Nuclear Energy Agency 285). The fume is then cooled in the condenser and sacked go into the blower, and the cycle rehashes itself. The fridge can be utilized as a climate control system on the off chance that it is ad libbed by putting the evaporator in an open spot that should be cooled. This is on the grounds that their method of activity is the equivalent. The main contrast is the size of the territory they are cooling. The transformation of warmth vitality to power has been had a go at utilizing a few physical marvels, in any case, the immediate change has not been completely accomplished; this is a direct result of the temperature

What affect did the Islamic invasion have on the history of Spain? THE IMPACT OF THE ISLAMIC INVASION ON SPAIN The history of Spain reflects the effect of certain cultures and religions on Spanish population, language, traditions and style of life. In the Middle Ages (about 411 AD) Spain was occupied by the German tribes and further the country was conquered by the Visigoths (416 AD) (Collins, 1995). However, the aim of this essay is to analyse the impact of the Islamic invasion on Spain, as the Muslims has had a considerable effect on the country up to the present day. In 711-714 the Umayyad dynasty seized the Spanish area near Cordoba (Rahman, 1989); forty years later Abd al-Rahman I created an Umayyad Emirate. But it was in the tenth century under the ruling of Abd al-Rahman III (912-961) that the Muslims managed to intensify Spains prosperity and wealth (Goodwin, 1990). Abdal-Rahman III united some areas of al-Andalus and improved military, tax and law systems. In the eleventh century the Emirate was divided into several kingdoms with unique cultures and traditions. After the decay of the Umayyad dynasty, other Islamic dynasties took control over Spain, such as the Almoravides, the Almohades and the Nasrids (Taha, 1989). At the end of the fifteenth century the Christian rulers seized the power in Granada and put an end to the Muslim ruling. Other Spanish places, such as Seville and Cordoba, were liberated from the Muslims by Ferdinand of Aragon and Isabella of Castile in the thirteenth century. But the Islamic influence has preserved in Spain till nowadays, though Isabella made everything to destroy Islam and eradicate any traces of the Muslims. The Islamic invasion positively affected many areas of life in Spain, such as culture, education, religion, economics, science, society and family. Al-Andalus, as the Muslims called Spain, had acquired the central position among other civilizations of the ancient world since the conquest of Cordoba by the Umayyad dynasty (Chejne, 1974). In particular, the Muslims created about two thousand public baths and mosques for different social groups and implemented some schools for poor children in Cordoba. Although some Spanish regions opposed the Muslim ruling, industry and trade were considerably advanced by the Umayyads (Harvey, 1990). Spanish libraries contained more than 400,000 books and the streets of Cordoba were illuminated, unlike such European capitals as Paris and London. As Hillenbrand (1999) puts it, Cordobain its prime had no peer in Europe for the amenities of civilized life. Its houses were bountifully supplied with hot and cold running water, its streets were lit at night (p.175). Different religious groups, such as Christians, Muslims and Jews, successfully interacted with each other. According to Ghazanfar (2004), there existed no separation between science, wisdom, and faith; nor was East separated from the West, nor the Muslim from the Jew or the Christian (p.2). Such religious tolerance can be explained by th e fact that the Muslims did not act as oppressors, but, instead, they tried to improve the living conditions of all social classes in Spain. As a result, Christians and Jews occupied the leading positions during the Muslim ruling (Hopfe, 1998). This peaceful co-existence of three religions had continued till the fifteenth century (Thomson, 1989), contributing to many aspects of life in Spain. For instance, in the eleventh century Arabic language was utilised in Spanish science and literature, while Spaniards began to learn the Muslims language to acquaint with Arabic writings (Shubert, 1992). Some Christians and Jews borrowed Arabic culture and religion, gradually transforming into Mozarabs, people who were Arabized (Watt, 1965). Many illiterate Spanish people learned to read and write, calculate and navigate (Houston, 1964). As the Muslims preserved some Roman and Greek literary works, Spanish Christians served as translators for these crucial manuscripts. Architecture, philosophy, mathematics and other sciences also prospered under the ruling of the Umayyad dynasty due to their belief in Allah and the laws of the Quran, the holy book of the Muslims that accentuated the power of knowledge (Fakhry, 1983). As the Muslims made attempts to understand God, they also tried to uncover the truth about human nature by conducting different researches and scientific investigations (Saud, 1994). For instance, the Muslims substituted the Roman number system existed in Spain for the Arabic number system that has been widely utilised in algebra, arithmetic and business since then. In addition, astronomy, medicine, biology and chemistry began to thrive in Spain after the Islamic invasion (Lewis, 1993). Among the most famous Spanish philosophers, writers, artists and scientists of the Muslim era are Al-Kwarizmi, Ibn Rushd, Ibn Zuhr, Al-Razi and Ibn Sina (Chejne, 1974). Ibn Sinas medical treatise Al-Qanun had been studied in many European educational estab lishments for about three hundred years and had been regarded as one of the best medical works (Vernet, 1992). One of the greatest Muslim scholars of Spain was Abu Zakariyah al-Awwam Ishibili who created a procedure of grafting and gave names to more than five hundred plants (Ghazanfar, 2004). Pedro Alfonzo, a Spanish Muslim scholar who was interested in astronomy, claimed that his wish was to raise once more to life the knowledge of that science which is in such a deplorable state among those educated in the Latin manner (Hermes, 1977, p.72). Due to such an advanced stage of scientific development, many European scientists arrived to Spain to receive knowledge in various sciences and to interpret Latin texts. In regard to economics, the Muslims created the silk industry in Al-Andalus, gradually transforming Spain into one of the largest countries for silk production. The country was also engaged in the production of satin, cotton, pepper, furs, clocks, paper, maps and soap s. Further Spain contributed to the fine fabrics manufacturing in Europe. Agriculture was poorly developed in Spain because of a primordial irrigation system (White, 1970; Semple, 1971); but the Muslims substituted this old system for a new improved irrigation method that resulted in the prosperity of orchards and the increase of rice crops in such areas as Granada and the Valenican huerta (Dickie, 1968). The Muslims utilised the method of Syrianization to improve agriculture of Spanish towns, especially Valencia and Seville (Burns, 1973). The new system allowed Spaniards to intensify crops with the help of artificial water supply (Smith, 1966, p.442). Up to the present day this irrigation system has been controlled by an old Muslim tribunal (Tribunal of the Waters); today this Tribunal is held once a week and is aimed at solving disputable agricultural issues. Due to these improvements, Spanish people began to cultivate various plants and trees, such as oranges, lemons, ar tichokes, apricots, olive and implemented an advanced system of nature protection (Imamuddin, 1965, p.84). Before the Islamic invasion, Spanish grew winter crops, but the Muslims managed to implement Indian crops that were grown in a frost-free season. As a result, many Arabic words were introduced in Spanish language to reflect different aspects of the irrigation system; for instance, alberca-al-birka means a pool and acequia-al-saqiya means an irrigation ditch. Nowadays some flowers bear the Arabic names, such asbellota-balluta for acorn, alazor-al-asfur for safflower and al-fasfasa foralfalfa. Other words reflect the impact of the Muslims on farming: tahona-tahuna (flour-mill), aldea-al-days (village), and rabadan-rabb al-dan (head-shepherd). As the Muslims were obsessed with nature, they utilised their artistic skills to create splendid gardens and buildings that have attracted attention of people till nowadays (Blair Bloom, 1994). Such unusual places as the Alhambra of Granda, the Mosque of Cordoba and the Alcazar of Seville are the visual legacy of the Muslims in Spain (Barrucand Bednorz,1992; Ettinghausen Grabar, 1987). These splendid architectural buildings clearly reveal the Muslims innovations in the fields of architectural design and style(King, 1978; Grabar, 1978; Rodriguez, 1992). Unfortunately, almost all Islamic architectural monuments were destroyed at the end of the fifteenth century; only the Alhambra remained undamaged (Fletcher, 1987). Many famous writers and artists depicted the Alhambra in their works (Ching, 1979). For instance, Washington Irving created Tales of the Alhambra when he visited this place in Spain. Despite the destruction of many Islamic buildings (Barrucand Bednorz, 1992), a new Islamic mosque for Spanish Muslims hasbeen recently built in Granada as a result of Islam renewal in 1989. The Muslims are able to pray in the mosque and receive education in such sciences as medicine and law. Today the number of the Muslims in Spain approaches to onemillion people who strongly defend their rights and their faith. Some Spanish Muslims continue to live in the Albaican quarter in Granada, where the Muslims lived in the 10-15 centuries. However, the tensions between Spanish Muslims and Spanish Christians are rather complicated, although Spanish government realises that it is crucial to improve the relations between these two religious groups. Analysing the impact of the Islamic invasion on the history of Spain, the essay suggests that the Muslims considerably affected such areas of Spanish life as economics, culture, science, architecture, art and religion. They managed to improve the countrys agriculture and manufacturing, contributing to its prosperity and wealth; they implemented many advanced systems based on scientific findings, especially Arabic number system of calculation, the illumination system and the irrigation method. The Muslims transferred their knowledge in medicine, a lgebra, chemistry, astronomy, architecture, art, nature and technology to Spanish people who further imparted these valuable data to other European countries. Thus, the Islamic invasion on Spain paved the way for the period of Renaissance in Europe; as Ghazanfar (2004) puts it, Muslims not only occupied Spain but planted the roots of European Renaissance through unparalleled transfer of knowledge in almost every field known (p.11). Today the Islamic influence is especially obvious in many Spanish words that reflect the Arabic roots, as well as in architectural monuments, literature, sciences, legal laws and cultural traditions. Although Islam was officially renewed in Spain at the end of the twentieth century, the Muslims continue to experience serious racial prejudices from the side of Spanish Christians. Don’t waste time!

We were not echoing him, we were protesting against getting our life back. What was the point? We closed our eyes again and listened to the pain in our body. We let that drown out the pain in our mind. â€Å"Look,† Uncle Jeb said after a moment. â€Å"I, uh, have something to take care of. You rest for a bit, and I’ll be back for you.† We didn’t hear the meaning in his words, just the sounds. Our eyes stayed closed. His footsteps crunched quietly away from us. We couldn’t tell which direction he went. We didn’t care anyway. They were gone. There was no way to find them, no hope. Jared and Jamie had disappeared, something they knew well how to do, and we would never see them again. The water and the cooler night air were making us lucid, something we did not want. We rolled over, to bury our face against the sand again. We were so tired, past the point of exhaustion and into some deeper, more painful state. Surely we could sleep. All we had to do was not think. We could do that. We did. When we woke, it was still night, but dawn was threatening on the eastern horizon-the mountains were lined with dull red. Our mouth tasted of dust, and at first we were sure that we had dreamed Uncle Jeb’s appearance. Of course we had. Our head was clearer this morning, and we noticed quickly the strange shape near our right cheek-something that was not a rock or a cactus. We touched it, and it was hard and smooth. We nudged it, and the delicious sound of sloshing water came from inside. Uncle Jeb was real, and he’d left us a canteen. We sat up carefully, surprised when we didn’t break in two like a withered stick. Actually, we felt better. The water must have had time to work its way through some of our body. The pain was dull, and for the first time in a long while, we felt hungry again. Our fingers were stiff and clumsy as we twisted the cap from the top of the canteen. It wasn’t all the way full, but there was enough water to stretch the walls of our belly again-it must have shrunk. We drank it all; we were done with rationing. We dropped the metal canteen to the sand, where it made a dull thud in the predawn silence. We felt wide awake now. We sighed, preferring unconsciousness, and let our head fall into our hands. What now? â€Å"Why did you give it water, Jeb?† an angry voice demanded, close behind our back. We whirled, twisting onto our knees. What we saw made our heart falter and our awareness splinter apart. There were eight humans half-circled around where I knelt under the tree. There was no question they were humans, all of them. I’d never seen faces contorted into such expressions-not on my kind. These lips twisted with hatred, pulled back over clenched teeth like wild animals. These brows pulled low over eyes that burned with fury. Six men and two women, some of them very big, most of them bigger than me. I felt the blood drain from my face as I realized why they held their hands so oddly-gripped tightly in front of them, each balancing an object. They held weapons. Some held blades-a few short ones like those I had kept in my kitchen, and some longer, one huge and menacing. This knife had no purpose in a kitchen. Melanie supplied the name: a machete. Others held long bars, some metal, some wooden. Clubs. I recognized Uncle Jeb in their midst. Held loosely in his hands was an object I’d never seen in person, only in Melanie’s memories, like the big knife. It was a rifle. I saw horror, but Melanie saw all this with wonder, her mind boggling at their numbers. Eight human survivors. She’d thought Jeb was alone or, in the best case scenario, with only two others. To see so many of her kind alive filled her with joy. You’re an idiot, I told her. Look at them. See them. I forced her to see it from my perspective: to see the threatening shapes inside the dirty jeans and light cotton shirts, brown with dust. They might have been human-as she thought of the word-once, but at this moment they were something else. They were barbarians, monsters. They hung over us, slavering for blood. There was a death sentence in every pair of eyes. Melanie saw all this and, though grudgingly, she had to admit that I was right. At this moment, her beloved humans were at their worst-like the newspaper stories we’d seen in the abandoned shack. We were looking at killers. We should have been wiser; we should have died yesterday. Why would Uncle Jeb keep us alive for this? A shiver passed through me at the thought. I’d skimmed through the histories of human atrocities. I’d had no stomach for them. Perhaps I should have concentrated better. I knew there were reasons why humans let their enemies live, for a little while. Things they wanted from their minds or their bodies†¦ Of course it sprang into my head immediately-the one secret they would want from me. The one I could never, never tell them. No matter what they did to me. You read "The Host Chapter 13: Sentenced" in category "Essay examples" I would have to kill myself first. I did not let Melanie see the secret I protected. I used her own defenses against her and threw up a wall in my head to hide behind while I thought of the information for the first time since implantation. There had been no reason to think of it before. Melanie was hardly even curious on the other side of the wall; she made no effort to break through it. There were much more immediate concerns than the fact that she had not been the only one keeping information in reserve. Did it matter that I protected my secret from her? I wasn’t as strong as Melanie; I had no doubt she could endure torture. How much pain could I stand before I gave them anything they wanted? My stomach heaved. Suicide was a repugnant option-worse because it would be murder, too. Melanie would be part of either torture or death. I would wait for that until I had absolutely no other choice. No, they can’t. Uncle Jeb would never let them hurt me. Uncle Jeb doesn’t know you’re here, I reminded her. Tell him! I focused on the old man’s face. The thick white beard kept me from seeing the set of his mouth, but his eyes did not seem to burn like the others’. From the corner of my eye, I could see a few of the men shift their gaze from me to him. They were waiting for him to answer the question that had alerted me to their presence. Uncle Jeb stared at me, ignoring them. I can’t tell him, Melanie. He won’t believe me. And if they think I’m lying to them, they’ll think I’m a Seeker. They must have experience enough to know that only a Seeker would come out here with a lie, a story designed for infiltration. Melanie recognized the truth of my thought at once. The very word Seeker made her recoil with hatred, and she knew these strangers would have the same reaction. It doesn’t matter anyway. I’m a soul-that’s enough for them. The one with the machete-the biggest man there, black-haired with oddly fair skin and vivid blue eyes-made a sound of disgust and spit on the ground. He took a step forward, slowly raising the long blade. Better fast than slow. Better that it was this brutal hand and not mine that killed us. Better that I didn’t die a creature of violence, accountable for Melanie’s blood as well as my own. â€Å"Hold it, Kyle.† Jeb’s words were unhurried, almost casual, but the big man stopped. He grimaced and turned to face Melanie’s uncle. â€Å"Why? You said you made sure. It’s one of them.† I recognized the voice-he was the same one who’d asked Jeb why he’d given me water. â€Å"Well, yes, she surely is. But it’s a little complicated.† â€Å"How?† A different man asked the question. He stood next to the big, dark-haired Kyle, and they looked so much alike that they had to be brothers. â€Å"See, this here is my niece, too.† â€Å"Not anymore she’s not,† Kyle said flatly. He spit again and took another deliberate step in my direction, knife ready. I could see from the way his shoulders leaned into the action that words would not stop him again. I closed my eyes. There were two sharp metallic clicks, and someone gasped. My eyes flew open again. â€Å"I said hold it, Kyle.† Uncle Jeb’s voice was still relaxed, but the long rifle was gripped tightly in his hands now, and the barrels were pointed at Kyle’s back. Kyle was frozen just steps from me; his machete hung motionless in the air above his shoulder. â€Å"Jeb,† the brother said, horrified, â€Å"what are you doing?† â€Å"Step away from the girl, Kyle.† Kyle turned his back to us, whirling on Jeb in fury. â€Å"It’s not a girl, Jeb!† Jeb shrugged; the gun stayed steady in his hands, pointed at Kyle. â€Å"There are things to be discussed.† â€Å"The doctor might be able to learn something from it,† a female voice offered gruffly. I cringed at the words, hearing in them my worst fears. When Jeb had called me his niece just now, I’d foolishly let a spark of hope flame to life-perhaps there would be pity. I’d been stupid to think that, even for a second. Death would be the only pity I could hope for from these creatures. I looked at the woman who’d spoken, surprised to see that she was as old as Jeb, maybe older. Her hair was dark gray rather than white, which is why I hadn’t noticed her age before. Her face was a mass of wrinkles, all of them turning down into angry lines. But there was something familiar about the features behind the lines. Melanie made the connection between this ancient face and another, smoother face in her memory. â€Å"Aunt Maggie? You’re here? How? Is Sharon -† The words were all Melanie, but they gushed from my mouth, and I was unable to stop them. Sharing for so long in the desert had made her stronger, or me weaker. Or maybe it was just that I was concentrating on which direction the deathblow was going to fall from. I was bracing for our murder, and she was having a family reunion. Melanie got only halfway through her surprised exclamation. The much-aged woman named Maggie lunged forward with a speed that belied her brittle exterior. She didn’t raise the hand that held the black crowbar. That was the hand I was watching, so I didn’t see her free hand swing out to slap me hard across the face. My head snapped back and then forward. She slapped me again. â€Å"You won’t fool us, you parasite. We know how you work. We know how well you can mimic us.† I tasted blood inside my cheek. Don’t do that again, I scolded Melanie. I told you what they’d think. Melanie was too shocked to answer. â€Å"Now, Maggie,† Jeb began in a soothing tone. â€Å"Don’t you Now, Maggie’ me, you old fool! She’s probably led a legion of them down on us.† She backed away from me, her eyes measuring my stillness as if I were a coiled snake. She stopped beside her brother. â€Å"I don’t see anyone,† Jeb retorted. â€Å"Hey!† he yelled, and I flinched in surprise. I wasn’t the only one. Jeb waved his left hand over his head, the gun still clenched in the right. â€Å"Over here!† â€Å"Shut up,† Maggie growled, shoving his chest. Though I had good reason to know she was strong, Jeb didn’t wobble. â€Å"She’s alone, Mag. She was pretty much dead when I found her-she’s not in such great shape now. The centipedes don’t sacrifice their own that way. They would have come for her much sooner than I did. Whatever else she is, she’s alone.† I saw the image of the long, many-legged insect in my head, but I didn’t make the connection. He’s talking about you, Melanie translated. She placed the picture of the ugly bug next to my memory of a bright silver soul. I didn’t see a resemblance. I wonder how he knows what you look like, Melanie wondered absently. My memories of a soul’s true appearance had been new to her in the beginning. I didn’t have time to wonder with her. Jeb was walking toward me, and the others were close behind. Kyle’s hand hovered at Jeb’s shoulder, ready to restrain him or throw him out of the way, I couldn’t tell. Jeb put his gun in his left hand and extended the right to me. I eyed it warily, waiting for it to hit me. â€Å"C’mon,† he urged gently. â€Å"If I could carry you that far, I woulda brought you home last night. You’re gonna have to walk some more.† â€Å"No!† Kyle grunted. â€Å"I’m takin’ her back,† Jeb said, and for the first time there was a harsher tone to his voice. Under his beard, his jaw flexed into a stubborn line. â€Å"Jeb!† Maggie protested. â€Å"‘S my place, Mag. I’ll do what I want.† â€Å"Old fool!† she snapped again. Jeb reached down and grabbed my hand from where it lay curled into a fist against my thigh. He yanked me to my feet. It was not cruelty; it was merely as if he was in a hurry. Yet was it not the very worst form of cruelty to prolong my life for the reasons he had? I rocked unsteadily. I couldn’t feel my legs very well-just prickles like needle points as the blood flowed down. There was a hiss of disapproval behind him. It came from more than one mouth. â€Å"Okay, whoever you are,† he said to me, his voice still kind. â€Å"Let’s get out of here before it heats up.† The one who must have been Kyle’s brother put his hand on Jeb’s arm. â€Å"You can’t just show it where we live, Jeb.† â€Å"I suppose it doesn’t matter,† Maggie said harshly. â€Å"It won’t get a chance to tell tales.† Jeb sighed and pulled a bandanna-all but hidden by his beard-from around his neck. â€Å"This is silly,† he muttered, but he rolled the dirty fabric, stiff with dry sweat, into a blindfold. I kept perfectly still as he tied it over my eyes, fighting the panic that increased when I couldn’t see my enemies. I couldn’t see, but I knew it was Jeb who put one hand on my back and guided me; none of the others would have been so gentle. We started forward, toward the north, I thought. No one spoke at first-there was just the sound of sand grinding under many feet. The ground was even, but I stumbled on my numb legs again and again. Jeb was patient; his guiding hand was almost chivalrous. I felt the sun rise as we walked. Some of the footsteps were faster than others. They moved ahead of us until they were hard to hear. It sounded like it was the minority that stayed with Jeb and me. I must not have looked like I needed many guards-I was faint with hunger, and I swayed with every step; my head felt dizzy and hollow. â€Å"You aren’t planning to tell him, are you?† It was Maggie’s voice; it came from a few feet behind me, and it sounded like an accusation. â€Å"He’s got a right to know,† Jeb replied. The stubborn note was back in his voice. â€Å"It’s an unkind thing you are doing, Jebediah.† â€Å"Life is unkind, Magnolia.† It was hard to decide who was the more terrifying of the two. Was it Jeb, who seemed so intent on keeping me alive? Or Maggie, who had first suggested the doctor-an appellation that filled me with instinctive, nauseated dread-but who seemed more worried about cruelty than her brother? We walked in silence again for a few hours. When my legs buckled, Jeb lowered me to the ground and held a canteen to my lips as he had in the night. â€Å"Let me know when you’re ready,† Jeb told me. His voice sounded kind, though I knew that was a false interpretation. Someone sighed impatiently. â€Å"Why are you doing this, Jeb?† a man asked. I’d heard the voice before; it was one of the brothers. â€Å"For Doc? You could have just told Kyle that. You didn’t have to pull a gun on him.† â€Å"Kyle needs a gun pulled on him more often,† Jeb muttered. â€Å"Please tell me this wasn’t about sympathy,† the man continued. â€Å"After all you’ve seen†¦Ã¢â‚¬  â€Å"After all I’ve seen, if I hadn’t learned compassion, I wouldn’t be worth much. But no, it was not about sympathy. If I had enough sympathy for this poor creature, I would have let her die.† I shivered in the oven-hot air. â€Å"What, then?† Kyle’s brother demanded. There was a long silence, and then Jeb’s hand touched mine. I grasped it, needing the help to get back on my feet. His other hand pressed against my back, and I started forward again. â€Å"Curiosity,† Jeb said in a low voice. No one replied. As we walked, I considered a few sure facts. One, I was not the first soul they’d captured. There was already a set routine here. This â€Å"Doc† had tried to get his answer from others before me. Two, he had tried unsuccessfully. If any soul had forgone suicide only to crack under the humans’ torture, they would not need me now. My death would have been mercifully swift. Oddly, I couldn’t bring myself to hope for a quick end, though, or to try to effect that outcome. It would be easy to do, even without doing the deed myself. I would only have to tell them a lie-pretend to be a Seeker, tell them my colleagues were tracking me right now, bluster and threaten. Or tell them the truth-that Melanie lived on inside me, and that she had brought me here. They would see another lie, and one so richly irresistible-the idea that the human could live on after implantation-so tempting to believe from their perspective, so insidious, that they would believe I was a Seeker more surely than if I claimed it. They would assume a trap, get rid of me quickly, and find a new place to hide, far away from here. You’re probably right, Melanie agreed. It’s what I would do. But I wasn’t in pain yet, and so either form of suicide was hard to embrace; my instinct for survival sealed my lips. The memory of my last session with my Comforter-a time so civilized it seemed to belong to a different planet-flashed through my head. Melanie challenging me to have her removed, a seemingly suicidal impulse, but only a bluff. I remembered thinking how hard it was to contemplate death from a comfortable chair. Last night Melanie and I had wished for death, but death had been only inches away at the time. It was different now that I was on my feet again. I don’t want to die, either, Melanie whispered. But maybe you’re wrong. Maybe that’s not why they’re keeping us alive. I don’t understand why they would†¦ She didn’t want to imagine the things they might do to us-I was sure she could come up with worse than I. What answer would they want from you that bad? I’ll never tell. Not you, not any human. A bold declaration. But then, I wasn’t in pain yet†¦ Another hour had passed-the sun was directly overhead, the heat of it like a crown of fire on my hair-when the sound changed. The grinding steps that I barely heard anymore turned to echoes ahead of me. Jeb’s feet still crunched against the sand like mine, but someone in front of us had reached a new terrain. â€Å"Careful, now,† Jeb warned me. â€Å"Watch your head.† I hesitated, not sure what I was watching for, or how to watch with no eyes. His hand left my back and pressed down on my head, telling me to duck. I bent forward. My neck was stiff. He guided me forward again, and I heard our footsteps make the same echoing sound. The ground didn’t give like sand, didn’t feel loose like rock. It was flat and solid beneath my feet. The sun was gone-I could no longer feel it burn my skin or scorch my hair. I took another step, and a new air touched my face. It was not a breeze. This was stagnant-I moved into it. The dry desert wind was gone. This air was still and cooler. There was the faintest hint of moisture to it, a mustiness that I could both smell and taste. There were so many questions in my mind, and in Melanie’s. She wanted to ask hers, but I kept silent. There was nothing either of us could say that would help us now. â€Å"Okay, you can straighten up,† Jeb told me. I raised my head slowly. Even with the blindfold, I could tell that there was no light. It was utterly black around the edges of the bandanna. I could hear the others behind me, shuffling their feet impatiently, waiting for us to move forward. â€Å"This way,† Jeb said, and he was guiding me again. Our footsteps echoed back from close by-the space we were in must have been quite small. I found myself ducking my head instinctively. We went a few steps farther, and then we rounded a sharp curve that seemed to turn us back the way we’d come. The ground started to slant downward. The angle got steeper with every step, and Jeb gave me his rough hand to keep me from falling. I don’t know how long I slipped and skidded my way through the darkness. The hike probably felt longer than it was with each minute slowed by my terror. We took another turn, and then the floor started to climb upward. My legs were so numb and wooden that as the path got steeper, Jeb had to half drag me up the incline. The air got mustier and moister the farther we went, but the blackness didn’t change. The only sounds were our footsteps and their nearby echoes. The pathway flattened out and began to turn and twist like a serpent. Finally, finally, there was a brightness around the top and bottom of my blindfold. I wished that it would slip, as I was too frightened to pull it off myself. It seemed to me that I wouldn’t be so terrified if I could just see where I was and who was with me. With the light came noise. Strange noise, a low murmuring babble. It sounded almost like a waterfall. The babble got louder as we moved forward, and the closer it got, the less it sounded like water. It was too varied, low and high pitches mingling and echoing. If it had not been so discordant, it might have sounded like an uglier version of the constant music I’d heard and sung on the Singing World. The darkness of the blindfold suited that memory, the memory of blindness. Melanie understood the cacophony before I did. I’d never heard the sound because I’d never been with humans before. It’s an argument, she realized. It sounds like so many people arguing. She was drawn by the sound. Were there more people here, then? That there were even eight had surprised us both. What was this place? Hands touched the back of my neck, and I shied away from them. â€Å"Easy now,† Jeb said. He pulled the blindfold off my eyes. I blinked slowly, and the shadows around me settled into shapes I could understand: rough, uneven walls; a pocked ceiling; a worn, dusty floor. We were underground somewhere in a natural cave formation. We couldn’t be that deep. I thought we’d hiked upward longer than we’d slid downward. The rock walls and ceiling were a dark purpley brown, and they were riddled with shallow holes like Swiss cheese. The edges of the lower holes were worn down, but over my head the circles were more defined, and their rims looked sharp. The light came from a round hole ahead of us, its shape not unlike the holes that peppered the cavern, but larger. This was an entrance, a doorway to a brighter place. Melanie was eager, fascinated by the concept of more humans. I held back, suddenly worried that blindness might be better than sight. Jeb sighed. â€Å"Sorry,† he muttered, so low that I was certainly the only one to hear. I tried to swallow and could not. My head started to spin, but that might have been from hunger. My hands were trembling like leaves in a stiff breeze as Jeb prodded me through the big hole. The tunnel opened into a chamber so vast that at first I couldn’t accept what my eyes told me. The ceiling was too bright and too high-it was like an artificial sky. I tried to see what brightened it, but it sent down sharp lances of light that hurt my eyes. I was expecting the babble to get louder, but it was abruptly dead quiet in the huge cavern. The floor was dim compared to the brilliant ceiling so far above. It took a moment for my eyes to make sense of all the shapes. A crowd. There was no other word for it-there was a crowd of humans standing stock-still and silent, all staring at me with the same burning, hate-filled expressions I’d seen at dawn. Melanie was too stunned to do anything more than count. Ten, fifteen, twenty†¦ twenty-five, twenty-six, twenty-seven†¦ I didn’t care how many there were. I tried to tell her how little it mattered. It wouldn’t take twenty of them to kill me. To kill us. I tried to make her see how precarious our position was, but she was beyond my warnings at the moment, lost in this human world she’d never dreamed was here. One man stepped forward from the crowd, and my eyes darted first to his hands, looking for the weapon they would carry. His hands were clenched in fists but empty of any other threat. My eyes, adjusting to the dazzling light, made out the sun-gilded tint of his skin and then recognized it. Choking on the sudden hope that dizzied me, I lifted my eyes to the man’s face.

Macbeth A Good Man Essays - Characters In Macbeth,

Macbeth: A Good Man A struggle is present in every tragedy, as a person tries to overcome their flaws and fit the mold of their ideal. William Shakespeare plainly defined a good man in the play "Macbeth". This goal by it's definition is a difficult one for any man to achieve. Prudence and logic, temperance and patients, as well as the vindication of honor are Shakespeare's defining characteristics of a good man. As with any well written tragedy, Macbeth's title character and hero had to fall from his place of greatness to see his faults and begin his agonizing climb back to his previous position. His position, that of a good man, was one that demanded respect in the beginning of "Macbeth". The Sergeant described Macbeth's honor and bravery to king Duncan in act I, scene 2. "For brave Macbeth_well he deserves that name_ Disdaining fortune, with his brandish'd steel, Which smoked with bloody execution, Like valour's minion carved out his passage Till he faced the slave;_" Macbeth defended his king's honor as well as his own, as Shakespeare showed a good man never backed down from a foe. In the later acts of the play, Shakespeare furthered the definition of a good man by portraying what a bad one was not. In Macbeth's darkest hours, he showed no sign of prudence and logic as he slayed king Duncan, and hired assassins to murder his friend Banquo. Macbeth displayed his temerity in act IV scene 1 saying, "_from this moment The very firstlings of my heart shall be The firstlings of my hand. And even now, To crown my thoughts with acts, be it thought and done;_" Macbeth was no longer the logical, thinking man whom many admired. He had become reckless, acting with only his passion and not his mind. The tragedy of the murders he brought on fair Scotland was a direct result of this violation of the criterion of a good man. The most apparent flaw, and perhaps the most tragic in Macbeth's character, is his lack of patients and temperance. These shortcomings haunted Macbeth, causing him to let his "overvaulting ambition" rush fate, and hasten his doom. Macbeth could not wait for an appointment to a position of more power. Instead, he murdered the king to take his place. Opting not to wait to see if Banquo would be loyal to him, Macbeth had his companion murdered. His impatience led Macbeth to listen to his wife, the witches, and his darker side. He again informed people what a good man was not. In the end, Macbeth did regain a shred of his previous distinction when he faced his adversaries like a true warrior. Macbeth's last words are those of a good man who faces his own problems. To Macduff he shouts his last words, "Before my bodyI throw my warlike shield. Lay on, Macduff,And damn'd be him that first cries, `Hold, enough!" Like a bear, Macbeth regains his seat of honor, and becomes in his last breath, a good man.
