Synthesis Reaction Description Plus Examples While there are many types of chemical reactions, they all fall into at least one of four broad categories: synthesis reactions, decomposition reactions, single displacement reactions, and double displacement reactions. A synthesis reaction or direct combination reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. The reactants may be elements or compounds, while the product is always a compound. General Form of Synthesis Reactions The general form of a synthesis reaction is: A B Ã¢â â AB Examples of Synthesis Reactions Here are some examples of synthesis reactions: Water:2 H2(g) O2(g) Ã¢â â 2 H2O(g)Carbon dioxide:2 CO(g) O2(g) Ã¢â â 2CO2(g)Ammonia:3 H2(g) N2(g) Ã¢â â 2 NH3(g)Aluminum oxide:4 Al(s) 3 O2(g) Ã¢â â 2 Al2O3(s)Iron sulfide:8 Fe S8 Ã¢â â 8 FeSPotassium chloride:2 K(s) Cl2(g) Ã¢â â 2 KCl(s) Recognizing Synthesis Reactions The hallmark of a synthesis reaction is that a more complex product is formed from the reactants. One easy-to-recognize type of synthesis reaction occurs when two or more elements combine to form a compound. The other type of synthesis reaction happens when an element and a compound combine to form a new compound. Basically, to identify this reaction, look for a product that contains all the reactant atoms. Be sure to count the number of atoms in both the reactants and the products. Sometimes when a chemical equation is written, extra information is given that might make it hard to recognize what is going on in a reaction. Counting numbers and types of atoms makes it easier to identify reaction types.

Favourite piece of classical music(critical review) - Essay Example Tensions seem melodic that they render my appreciation grow with intense curiosity from one level on to the next as if a wide-eyed scene shut into suspense. It is as if a particular story were being weaved movement upon movement like an act in a play, while the tempo brings indications where tragedy must come in, the point to remain as such or otherwise jolt-free as though there were magical winds. With its unique style, the sound of antiquity becomes special that I suddenly feel the ease to span out of my modern musical inclination and reconcile with it each aspect of distortion and fluidity therein. As a consequence of a well-arranged composition, it seems there is automatic connection somewhere with the perfectly climatic lute instrumentation. I could sense that others watching with me at the time are being made repeatedly optimistic in the process, not initially expecting to have tuned the symphonies in as eventful as it is wonderfully tragic along the transformation of tamed notes to voracious ones, worthy of encore. In the process, it is particularly captivating to have experienced the detailed rhythmic approach of the Passamezzo della BattagliaÃ which splendidly attempts to be classic in every way effecting a pitch very much congruous with good-humored facial expressions of the musicians. Having studied European history, I could imagine how lute dynamics had been deemed necessary in the type of secular culture between the medieval and renaissance periods. It is such a momentous performance for the celebrated lute players assuredly filled with inspiration that in my entrancement brings across invisible waves of tunes in fluid rush marked by certain jest. I come snapping back to reality every time as if from subconsciously stepping onto a whole new dimension where imaginings just soar and spirits are lifted to cosmic heights. It is I suppose all about each musicianÃ¢â¬â¢s craft with his lute that defines and sets his style apart from a traditional

A Rose for Emily - Research Paper Example This situation injured Emily and her world was divided into before and after. Representing the main character the author makes an allusion to the New South. By such type of personification and allusion the author shows the New South as independent and mighty fighter for rights. The story is worth-discussing, thus the given paper will try to answer the question why Emily arouses sympathy with readers notwithstanding that she is a murderer. The first issue that will be discussed is the correlation of past and present as well as their confrontation. The main heroine Emily still lived in her past, thus she suffered a lot. She was not ready to get rid of the ties, which were important for her. From this side the murder of Homer can be easily explained. She did it intentionally. He was her lover and she wanted to keep him and the feeling, so the best way to do that was to murder him. The reader can feel a motif of independence and superciliousness. Emily scorned all the tittle-tattles abou t her private and social life that appeared in the town. Her relations with her beloved Homer belonged to her private life and the main problem of her social life was her refusal to pay taxes that became the subject of gossips. The act of murder can be interpreted as a symbol of independence. We can notice that this independence is also portrayed in her appearance. Ã¢â¬Å"She carried her head high enough - even when we believed that she was fallen. It was as if she demanded more than ever the recognition of her dignity as the last Grierson; as if it had wanted that touch of earthiness to reaffirm her imperviousnessÃ¢â¬ (p.82). Iron-grey hear of Emily arouses a number of associations. Emily tried to live and conduct her personal life without any superstitions. The important question is what the hidden sense is and how it was depicted by the author. There are a lot of interpretations that refer to the plot of this story, its concealed meaning and secret sense. It is essential one s hould pay special attention to the methods and devices, which were applied by the author to create intrigue. Faulkner is not only a great narrator, but also a master of symbolism and characterization (O'Connor). It was mentioned that the iron-grey hair of Emily symbolized strength and independence. Another important symbol is the rose. It is one of the main and the most significant symbols in the story. If to analyze the story deeper it is possible to see that characters of the story are the prototypes of Old and New South (Fetterley 194). In order to understand the character of the main heroine better, it is essential to pay special attention to Homer Barron; the author depicted him as one of those men who liked to drink with younger guys. Women usually do not like such behavior and Emily was not an exception: Ã¢â¬Å""She will persuade him yet," because Homer himself had remarke

Uniqueness and Importance of Medieval Music Essay The musical component of the medieval period is noted to have been one of the most important musical experiences in history. Every aspects of medieval music that have survived left legacies that deeply impact both the sacred and secular musical structure of today. Nonetheless, the music that permeated at that period has tangibly contributed in the musical heritage and tradition of present day society, most especially those of the Catholic Church. In this regard, it is therefore an imperative to look back on the historical overview of medieval music and its importance in the field of music as a whole. Medieval Music Medieval music is identified as the music that permeated in Europe during the middle or medieval ages. The said era covered the periods ranging from the Roman EmpireÃ¢â¬â¢s fall and ascent of Gregory the Great to papacy, until approximately the early fifteenth century. This form of music excludes that of the Byzantine Empire, which is noted to have a separate development. Basically, medieval music is divided into two principal categories: the sacred and secular. As Christianity was a dominant force during the medieval era, entire musical style was developed in order to support it. Therefore, sacred music was either inspired or set by the biblical text. Sacred music was originally composed in order to pay homage to God. Unlike sacred music, secular music has not been observed early in the said period. Yet medieval secular music played a significant role during the medieval period as it was created for the purpose of its entertainment value such as for dance or expressing ones love, which deeply reflects the lifestyle during that era (Ã¢â¬Å"Medieval music: Birth of polyphonyÃ¢â¬ ). Early Medieval Sacred Music Chant The earliest body of song documented from the medieval period was the chant, which is sometimes referred to as plainchant or plainsong. Chant is a monophonic, or music with just one part, which has been the earliest form of music used by the Catholic church. The account of the nun Egeria from her pilgrimage to Jerusalem from circa 400 AD was noted as the earliest evidence of plainchant practice. The account includes descriptions pertaining to psalms and singing (Cyrus). The evolution of chant was accounted to various regional liturgies like the Roman, Gallican, Celtic, Ambrosian, Mozarabic and the likes. Likewise, the traditions of the Byzantine Church as well as the Jewish synagogueÃ¢â¬â¢s psalm singing were pointed as strong influences in the emergence of chants (Ã¢â¬Å"Medieval musicÃ¢â¬ ). Over the next years, the practice of chant continued to develop until it became an important component in the mass and office that is familiar among the students of the medieval church (Cyrus). It is noteworthy that the adaptation of chant in the liturgical practice was a result of the religious reforms spearheaded by Charlemagne, who perceived the church as an important body that would enable him to unify his empire. He then replaced the regional varieties of plainsong with a single unified version. According to biographers, approximately in the ninth century Charlemagne decided to ask for the supervision of Rome in order to have the doctrinally unified versions of the chant. The resultant liturgical practice is commonly known as the Ã¢â¬Å"Gregorian Chant,Ã¢â¬ which is acknowledged as the central musical tradition in Europe during the medieval period (Ã¢â¬Å"Medieval musicÃ¢â¬ n. p. ). Gregorian chant was named so in honor of Pope Gregory I, who is believed to have organized around 3,000 melodies for the Roman Catholic worship. Such form of chant interblend ancient melodies, coming from the oral traditions of sources like Greek, Hebraic and Eastern, with the early Christian churches liturgical prayers (Pen). It is believed that many of the Gregorian chants were written in the western monasteries during the reign of Charlemagne (Ã¢â¬Å"Medieval musicÃ¢â¬ ). The music of the church is divided into chants used for the mass and for the office. Chants for the mass are a combination of celebrating the word of God and the Holy Eucharist, while chants for the office or ordinary are those that are part of the churches daily services which includes psalms and prayers. The text that change daily are known as Ã¢â¬Å"proper,Ã¢â¬ while the stable texts which are repeated for most of the church services are tagged as Ã¢â¬Å"ordinaryÃ¢â¬ (Cyrus n. p. ). Plainchant fuses text and tunes so as to function as a prayer, while the Latin text serves as the musical rhythm dictator in order for the text and tune to exactly correspond with each other. Normally, the melodic contour of such music is shaped by the words direction, which is set syllabically, making the text understandable. Other chants are also set in a melismatical manner where in Ã¢â¬Å"one syllable is sustained over several notesÃ¢â¬ for the purpose of ornamenting and emphasizing important syllables (Pen 119) and neumatic melodies where the music contains two to five notes for each syllable. Every service is embedded with a mixture of the said styles, making the liturgical action more dramatic (Cyrus). Notation The Carolingian cantors adapted almost four thousand chants every church year. In order to organize the imported chants they developed systems that organize the musical materials involved. As music during the early medieval period was not written down, the pressures of memorizing every song is perhaps the very reason why the Carolingian cantors created the system of notation. The system of church modes, wherein chants are classified according to their range, central pitch or final and melodic idioms were also developed. Alongside with the development of notation systems, liturgical books became widespread, regularizing the liturgical practice (Cyrus). Notation Improvements By the end of the ninth century until the 12th century both composers and performers created means for the liturgical process to prosper. Various feasts were developed alongside with new chants. Liturgical compositions from the past were copied through the use of a new system known as staff notation which was developed by Guido of Arezzo. Such notation was able to specify pitches of a melody through the combination of staff or set of horizontal lines and one or more clefs in order to identify the pitches of the chant. Guido also created a sightsinging system involving solmization, a process where pre-assigned syllables are used for certain pitches (Cyrus). Additionally, other improvements in the sacred medieval music were observed such as the polyphony. Early polyphony As plainchant was sung slowly and without rhythm or harmony, perhaps sacred composers grew weary of the chants and began experimenting with their music by adding musical lines in order to create harmony. This is known as polyphonic music, which gave birth to harmony. Around the end of ninth century, monastery singers like SwitzerlandÃ¢â¬â¢s St. Gall added voice in parallel motion to the chant, wherein they can sing in perfect musical intervals of the fourth and fifth together with the original tune. Such development is known as Ã¢â¬Å"organum,Ã¢â¬ which is considered as the beginning of Ã¢â¬Å"counterpoint,Ã¢â¬ an important feature of music where Ã¢â¬Å"two or more melodic strands occur simultaneouslyÃ¢â¬ (Ã¢â¬Å"Medieval musicÃ¢â¬ n. p. ). From then on, the organum developed into several ways. The Ã¢â¬Å"Florid organumÃ¢â¬ is one of the most significant forms of organum that was developed around 1100 in the south-west of France. Also referred to as the school of St. Martial, named after a monastery in France that is noted to have the best-preserved manuscripts of such musical style, Ã¢â¬Å"Florid organumÃ¢â¬ is incorporated within the chants in such a way that the original tune is being sung in long notes, while another voice would serve as an accompaniment by singing many notes to each of the original piece that is often done in Ã¢â¬Å"highly elaborate fashionÃ¢â¬ in order to further emphasize the perfect consonances of the music (Ã¢â¬Å"Medieval musicÃ¢â¬ n. p. ). Middle Medieval Music Subsequent developments of the organum took place in England, specifically at Notre Dame in Paris, which is said to be the center of musical creativity all through the 13th century. The emergence of the Notre Dame School of Polyphony around 1150 until 1250 is said to be the vehicle for a more modernized form of the organum, and paved way for the beginning of Ã¢â¬Å"Ars AntiquaÃ¢â¬ Ã¢â¬âa period in which rhythmic notation is recognized in the Western music; a period that greatly applies the method of rhythmic notation which is known as the rhythmic modes (Ã¢â¬Å"Medieval musicÃ¢â¬ n. p. ). Basically, Notre Dame organum employs three distinct rhythmic styles that adheres to the rhythmic modes: (1) Ã¢â¬Å"organum purumÃ¢â¬ wherein both upper and lower voice freely moves without a specific rhythm to follow, (2) Ã¢â¬Å"copulaÃ¢â¬ which upper voice moves in accordance to a strict rhythm while the lower voice moves freely, and (3) Ã¢â¬Å"discantÃ¢â¬ wherein both the upper and lower voice follows a strict rhythm (Cyrus n. p. ). Also this period, the concept of formal structure emerged, allowing composers to become more attentive with proportions, architectural effects and musical texture. Composers of the said period created various musical forms such as the Ã¢â¬Å"clasulae,Ã¢â¬ melismatic (technique of placing several noted in a single syllable of text) parts of the organa are extracted and fitted with new wordings so as to improve musical elaboration; the Ã¢â¬Å"versusÃ¢â¬â¢ or the Ã¢â¬Å"monophonic conductusÃ¢â¬ has a structure known as strophic, wherein the music is repeated for each successive stanza of the liturgical reading or poetry; and the Ã¢â¬Å"tropeÃ¢â¬ where new musical and textual materials are added to a pre-existing liturgical composition, most especially the introductory chants of the mass and the short chants of the ordinary. Trope singers, which are usually soloist, can come before, in the middle or after the host chant or choral; they simply amplify the meaning of the original composition. In some cases, tropes inject dialog and short interludes within the music; as such, they are though to be the forerunners in the field of liturgical drama which also emerged in this period (Cyrus n. p. ). Ã¢â¬Å"SequenceÃ¢â¬ also emerged during the era of liturgical consolidation in the medieval period. Ã¢â¬Å"SequenceÃ¢â¬ is identified as a separate form of choral composition that follows the Alleluia during mass. Credited to Notker Balbulus, sequence is a syllabic genre that contains irregular phrase lengths. In this type of chant genre, the musical lines normally contain one to four clauses, while the entirety of the music is often repeated before starting a new musical material (Cyrus n. p. ). The Ã¢â¬Å"motetÃ¢â¬ is profoundly one of the most significant forms of music created during the Middle Ages, specifically during the early parts of the Notre Dame period. Made out of the clausula, motet is focused on the usage of multiple voices, as stated by European composer, Perotin. Motet was further developed into a greater form of musical elaboration and sophistication during the 14th century which is noted as the era of Ã¢â¬Å"Ars NovaÃ¢â¬ (Ã¢â¬Å"Medieval MusicÃ¢â¬ ). Secular Music Although the plainchant was dominant in the sacred musical landscape of the middle age, other musical forms were used for the purpose of secular expression (Pen 119). Secular music existed in the shadow of secular music during the medieval period as most of the music scribes in this era were inclined in the creation of sacred music. Likewise, Medieval secular music was usually passed along orally and are rarely written down. As such, only limited number of composition has survived. Nonetheless, those existing copies of secular music serve as a vehicle for present day people to view the life at court in town during Middle Age. One of the earliest surviving music in secular form was accounted to the Goliards, who are wandering poet-musicians in Europe during the tenth until the mid-thirteenth century. Their secular compositions were consolidated in an early thirteenth century musical collection known as the Ã¢â¬Å"Carmina Burana. Ã¢â¬ However, due to the unclear notation, the reconstruction of the actual secular melodic sounds created by the Goliards was impossible, except for some pieces that have similarities with sacred music (Cyrus n. p. ). Most of the poetry created by the Goliards are secular in form, while some songs celebrate religious ideals and others are notably profane that tackles drunkenness, lechery as well as debauchery (Ã¢â¬Å"Medieval MusicÃ¢â¬ ). The secular music of the Troubadours of southern France and the Trouveres of the northern region are said to be the largest collection of secular music. The music created by the said groups are from their poems and utilized the vernacular tradition of monophonic secular music that are probably accompanied by varying instruments and performed by professionals ranging from skilled poets, singers and instrumentalists. Likewise, their poems have adopted the language of their regionsÃ¢â¬âTroubadours used lyrics written in Occitan also referred to as old Provencal or langue dÃ¢â¬â¢oc while the Trouveres used old French or langue dÃ¢â¬â¢oil. The music of the Troubadours was complimentary with the cultural life of Provence. Typically, their music describes war, courtly love and chivalry. Troubadour musical period lasted through the twelfth century until the first decade of the thirteenth century. The abrupt end of the Troubadour period was accounted to the Albigensian crusade, a campaign spearheaded by Pope Innocent III, which aims to eliminate Albigensian heresy, thererby eliminating the whole civilization of the Troubadours. Troubadour survivors of the fierce campaign migrated to Spain, Northern France or Northern Italy, where their musical inclination is said to have contributed in the secular music tradition of the said places (Ã¢â¬Å"Medieval MusicÃ¢â¬ ). The music of the Trouveres, on the other hand, was similar to that of the Troubadours. However, they were unaffected by the extermination directed towards the Albigenses unlike the Troubadours, allowing their music to survive until the thirteenth century. Most of the 2,000 surviving songs of the Trouveres showed musical sophistication that deeply highlights the poems it accompanied. Other than the Goliards, Troubadours and Trouveres, vast numbers of secular songs were also composed by civilization such as the Minnesingers, who are said to be the German counterpart of the Troubadours and Trouveres, and the Flagellants, who were noted for the geisslelieder songs that aims to appease the anger and wrath of God through this penitential music along with the mortification of their bodies (Ã¢â¬Å"Medieval MusicÃ¢â¬ ).

1984 is a political parable. While Brave New World describes a future of everyone getting exactly what they want, George Orwell takes this in the opposite direction with a description of how the world most likely will be: mindless, loveless, unfeeling followers of nothing. The first paragraph of the story already foreshadows of what is to come with a description of Victory Mansions, the home of Winston Smith, the protagonist of this story. It tells of the Ã¢â¬Å"swirl of gritty dustÃ¢â¬ ¦ The hallway smelt of boiled cabbage and old rag mats.Ã¢â¬ Even the names of places are depressing. He lives in the province of Airstrip One, the city of London, and in the country of Oceania. The other two countries are Eastasia and Eurasia. Big Brother, a fictional or real personÃ¢â¬âno one really knowsÃ¢â¬âis the leader of this miserable system of IngsocÃ¢â¬âEnglish Socialism, that is. No one is allowed to hold ideas different from those of the official propaganda outlet: Minitruth. T o enforce these laws, Big Brother uses many means, the first and foremost of these being the Thought Police, a corps of law officers who monitor the populace through undercover agents, infinite amounts of surveillance cameras and hidden microphones, and a two-way television screen that can be turned down, but never off. A new language is also being introduced to retard thought: Newspeak. This new English dialect uses shortened and compacted forms of modern day words that subconsciously facilitate the assimilation of misinformation through the omission of instances such as Ã¢â¬Å"scienceÃ¢â¬ , Ã¢â¬Å"freedomÃ¢â¬ , and Ã¢â¬Å"religion.Ã¢â¬ This, obviously, is a very bleak existence, and Winston, the oddball out, realizes it. Two characters besides Winston are brought into the plot. OÃ¢â¬â¢Brian is an extremely famous party member who Winston suspects is really a traitor member of the underground Ã¢â¬Å"The BrotherhoodÃ¢â¬ led by the ex-Party member Goldstein. The other is a young girl, Julia, who he hates for her commitment to an Anti-sex league, and suspects of spying on him. And so, depressed, lonely, and ever conscious of the PartyÃ¢â¬â¢s Minitruth slogan, Ã¢â¬Å"Who controls the past, controls the future: who controls the present controls the past,Ã¢â¬ he begins to search for the truth of the past, the rise to power of the current system, and, overall, the truth of his existence. The plot develops as he finds Julia is actually in love with him, and OÃ¢â¬â¢Brian seems to be making overtures to Winston on the subject of The Brotherhood.

Like other social scientists, systematically looking for general patterns in human behavior is the main work that anthropologists take on. They also develop theories and use scientific methods to test their research as they struggle to determine their differences and similarities in urban, industrial and cross-cultural societies.Its important feature is always its emphasis on the insiderÃ¢â¬â¢s view of a society. It aims to provide an understanding of the various cultures as it determines how people of a culture view the world. Thus, discoveries and studies in anthropology ultimately contribute to international harmony and with respect to the beliefs and values each one possess.Theories in AnthropologyVarious theoretical movements have been identified and studied and most of the principles frequently overlap or contradict each other altogether.Ã Some concentrate on past civilizations while some study on present ones (McGee, 2004).In the book of Thomas Kuhn, several theories were Ã¢â¬Å"stimulatedÃ¢â¬ and were based on a positivist epistemology. Historical Particularism, Culture and Personality, Structuralism and Functionalism as well as many others comprise the broad spectrum of Anthropology.But there are theories as well that alter the premise that dichotomizes the relationship between reality and theory and these are the theories that are influenced by post-modern perspectives such as the theory of Interpretivists and Constructivists. To further breakdown and understand how each school of thought works, defining the main themes and how they differentiate from one another will categorize each movement and its impact, if any, to present studies.Evolutionism in the Nineteenth Century claims that societal groups developed according to one universal order of cultural evolution (McGee, 2004).Ã Stated simply, the proponents of this theory identified Ã¢â¬Å"universal evolutional stagesÃ¢â¬ and have classified different societies as savage, barbarian civ ilization.They came to this conclusion by studying the data they have collected from traders and missionaries in the study of the various cultures they were interested in.Although most theorists rarely went to the societies they were analyzing, they organized the data they have collected, albeit second-hand data, and applied a general theory to all societies. Thus was born the train of thought placing Western Societies with rather advanced technologies and placing these societies at the highest rank of civilization (Erickson, 2008).The main theme that categorizes this movement is the assumption that human minds share similar characteristics all over the world (Moore, 2004). Does this mean that all people and their societies will go through the same processes of development? It seems so for another underlying assumption is all that belong to Western Societies are superior to other societies in the world.This assumption may be based on the fact these same societies possess the militar y and economic power against technologically simple societies (McGee, 2004). But can this then apply to other aspects of societies, such as kin systems, religion and childrearing customs? There is a logical progression that cannot be denied and this can be observed in the use of simple tools to using complex technology in most Western Societies.However, this train of thought offers a rather simplistic explanation on the development of Western Societies. Generally, it became too racist and during that time, Henry Morgan believed that evolution only moved from early societies to the Western societies.He also argued that intelligence is not a valid point to be raised for all people in various societies have different levels of intelligence and supported as well by Burnett Tylor.This theory was strongly attacked by supporters of the Historical Particularism for they see this theory as too speculative and ethnocentric and at the same time, approaches as too materialistic and the views on the various cultures are influenced by the Marxist Anthropology (McGee, 2004).Historical ParticularismÃ¢â¬â¢s main point is to focus its research on a specific society, its whole and its own history richly detailing the cultural traits and characteristics into its descriptive technology (Erickson, 2008). Franz Boas primarily led other theorists to support ethnography method instead of the comparative method, stressing the importance of a solid and intensive ground work research.He was considered the Father of American Anthropology because he openly challenged the proponents of the previous theory who he believed are overtly racist in nature and is responsible for influencing a large number of ethnographers who include Kroeber, Lowie, Spier, Wissler, Mead, Radin, Bunzel, Sapir, Benedict, Herskovits, Hoebel and many others like him ( Moore, 2004).The problem however with this theory is that it has very little stimulation resulting in a static view of cultures and did not develop a sense of cultural dynamics and continuities. It however laid the ground work for systematic field work and research.Structuralism is best exemplified by a leading intellectual of the age, published extensively his writings and revolved his theory around the basic question, Ã¢â¬Å"what are the human patterns of thought that bring order to the world?Ã¢â¬ bringing to the forefront the other question, Ã¢â¬Å"how does man deal with chaos?Ã¢â¬ Levi-StraussÃ¢â¬â¢ stressed the main points of this theory that the mind takes varied and potentially chaotic experiences to attempt to logically structure this experiences in binary configurations, and incorporating these with dominant images and symbols we come across in the world (McGee, 2004). Levi-Strauss believed that these configurations is an unconscious process devoid of being developed and articulated but instead deeply rooted from the structures of the mind.He argued that since all people of all cultures utilize binary principles t o organize and structure the experiences they encounter daily, the manner of comprehending the meaning to any quality must logically have an antithesis or opposite. This explains the rise of various symbols in human societies that run through symbolic polarities like right-left, moon-sun, female-male, life-death, and good-evil.The major contribution of this theory is the logical study of myth and thinking where knowledge communicate a significant message about how things are organized and specifically mediate or lessens experiential contradictions (order to chaos) and introducing an anomalous element Ã¢â¬â virgin mothers, garden of eden ( Evolutionism, 2008).This theory used a non empirical approach in its methods where most positivists ague and they believed that the structures of thinking should be based on binary principles. They also believed that all forms of thinking are logical and not less significant and the tools are just the things that differ at the way one processes the information around him.

My son says my car smells like candy. This is not because I satisfy some sugar craving while driving, but because I waxed it with the same wax used to coat many candies. This is carnauba wax, also known as palm wax or Brazil wax. What is carnauba wax? Carnauba wax is an ingredient in many foods and household products. Heres a look at what carnauba wax is made of and the properties that make it such a useful chemical. Carnauba Wax Origin Carnauba wax is a natural wax. ItÃ comes from the leaves of the Copernicia prunifera palm grown only in Brazil. The wax is obtained by beating the wax off of the dried palm fronds and then refining it for use. The pure wax is yellow in color. Carnauba Wax Chemical Composition Carnauba wax consists of fatty acid esters (80-85%), fatty alcohols (10-16%), acids (3-6%) and hydrocarbons (1-3%). It is around 20% esterified fatty diols, 10% methoxylated or hydroxylated cinnamic acid, and 6% hydroxylated fatty acids. Properties and Uses Carnauba wax has a very high melting point of 82-86 Ã °C (180-187 Ã °F). It is harder than concrete and nearly insoluble in water and ethanol. It is non-toxic and hypoallergenic. It can be polished to a high gloss. The combination of properties leads to many applications, including use in food, cosmetics, automobile and furniture wax, molds for semiconductor devices, and as a coating for dental floss. You use products that contain carnauba wax every day, though you may not have known what the ingredient was or where it came from. It is one of those extremely useful natural chemicals and renewable resources that doesnt have a synthetic equivalent. As for my car smelling like candy: the wax does have a distinctive sweet scent. It might be more accurate to say many car waxes and candies smell like carnauba wax.
