Solutions, Suspensions, Colloids, and Dispersions

Solutions, suspensions, colloids, and other dispersions are similar but have characteristics that set each one apart from the others. Solutions A solution is a homogeneous mixture of two or more components. The dissolving agent is the solvent. The substance that  is dissolved is the solute. The components of a solution are atoms, ions, or molecules, making  them 10-9 m or smaller in diameter. Example: Sugar and water Suspensions The particles in suspensions are larger than those found in solutions. Components of a suspension can be evenly distributed by mechanical means, like by shaking the contents but the components will eventually settle out. Example: Oil and water Colloids Particles intermediate in size between those found in solutions and suspensions can be mixed in such a way that they remain evenly distributed without settling out. These particles range in size from 10-8 to 10-6 m in size and are termed colloidal particles or colloids. The mixture they form is called a colloidal dispersion. A colloidal dispersion consists of colloids in a dispersing medium. Example: Milk Other Dispersions Liquids, solids, and gasses all may be mixed to form colloidal dispersions. Aerosols: Solid or liquid particles in a gasExamples: Smoke is solid in a gas. Fog is a liquid in a gas. Sols: Solid particles in a liquidExample: Milk of Magnesia is a sol with solid magnesium hydroxide in water. Emulsions: Liquid particles in a liquidExample: Mayonnaise is oil in water. Gels: Liquids in solidExamples: Gelatin is protein in water. Quicksand is sand in water. Telling Them Apart You can tell suspensions from colloids and solutions because the components of suspensions will eventually separate. Colloids can be distinguished from solutions using the Tyndall effect. A beam of light passing through a true solution, such as air, is not visible. Light passing through a colloidal dispersion, such as smoky or foggy air, will be reflected by the larger particles and the light beam will be visible.

Immigration and Islam Netherlands and France Free Essays

Immigration and Islam in France and the Netherlands After the post-war, WWII, era Europe faced a shortage of labor, at the same time it had to rebuild its infrastructure and economy. France and Netherlands both faced the same problem and like their counterparts in Europe they found the answer in guest-workers. These guest workers were immigrants from former colonies and other developing countries. We will write a custom essay sample on Immigration and Islam Netherlands and France or any similar topic only for you Order Now However, these guest-workers later settled down and brought their families. This led to a larger influx of immigrations. The largest, most significant, and most controversial are the Muslim immigrants. This study will focus on the different approaches of integration France and the Netherlands have implemented, the growing discrimination of Muslim immigrants, and the role Islam has in this dilemma. France had a long colonial history in the Maghreb, North Africa, mainly Algeria. To fill in this gap many male immigrants flocked to France in need of work. There was also a large immigration from the Mediterranean, Turkey, in this case. The largest make-up of French immigrants have been Algerians and others from the Maghreb. Netherlands, similar to the French had immigrants from the Mediterranean, Maghreb, and former colonies (Surinam and Antilles); the largest group being Turkish and Moroccan immigrants. These immigrants became a large factor in the rebuilding of the economy but as the economy slowed immigration became more of a problem for Western European countries. France proposed an assimilation model, where it endorsed pluralism in the private sphere. The Laicite, the separation of Church and State/private and public played a large role in the French system of assimilation. In the public sphere you were expected to be French in language and ideals. The private sphere was left for your own beliefs and customs. This can be seen in the expression of symbols in the public schools, where wearing the veil is not allowed because it threatens this division of public and private. However, this still doesn’t explain the dilemma that many second or third generation French citizens from immigrant backgrounds face. Even though they are â€Å"French†, they are not accepted by the system—accordingly because they still aren’t â€Å"French† enough. This creates disparity on both sides; the French politicize this dilemma by taking a harder stance on immigration and assimilation, giving rise to far-right parties like National Front under Le Pen. (GS, page 123) The immigrants unfortunately at times result to violent riots in protest and anger at the discrimination they face. The end result being stricter immigration regulations, more assimilation, and seeing â€Å"Islam† as incompatible to European standards. The Netherlands have the same end results but have come to them from a totally different background. The Netherlands has endorsed a multicultural integration from the beginning. (Coenders, M. , Lubbers, M. , Scheepers, P. , Verkuyten, M. (C. L. S. V)) The Netherlands have been one of the foremost in democracy and liberalism, ranking third in the world. Its capital, Amsterdam, is the hub liberal and free lifestyle. Since the 2000’s homosexual marriage and euthanasia have been legalized. (GS 192) Compared to France’s full assimilation the Netherlands has put forward a multiculturalism approach, however this has taken a drastic change in the last decade, especially against Muslim immigrants. In the early 2000’s Pim Fortuyn, a leader of anti-immigration and pro-assimilation party (Liveable Netherlands and latter List Pim Fortuyn), voiced his opinion on Islam being a backwards religion and a threat to liberal European/Dutch ideals. Even though both countries had different policies of integration they both ended up in the same situation against Muslim immigration. How can these phenomena be explained in these democracies that embrace liberal ideals? For it was France, that in 1789, coined the motto, â€Å"All men are born free and equal†, but now it can be seen that some men are born more free and equal than others. The realistic conflict theory explains this situation as a reaction to materialistic scarcity; jobs and housing. In the post-war era there was a surplus of jobs and also the need of cheap labor, the immigrants rushed in and filled these positions. However, after the slowing of the economic boom employment became scarcer. This led to higher un-employment rates and the native citizens started to see immigrants as a threat, leading to discrimination and pro-assimilation. Though this does explain a significant factor, there is still the growth of anti-Islamic sentiments. The Muslims aren’t the only immigrants in France or Netherlands, but they are the ones who face the blunt of the attention. (C. L. S. V) So the realistic conflict theory falls short in explaining this. More than Two Decades of Changing Ethnic Attitudes in the Netherlands, a study done to explain the attitudes the Dutch had on immigration, saw that social and ideological contents also affect peoples outlook as much as materialistic means. (C. L. S. V) This gives explanation to far-right parties such as List Pim Fortuyn and Le Pen. The parties that use anti-Islamic and anti-immigration sentiments as political platforms, they play on the fears’ of the people. Yet, how is it that these fears can grow and flourish in such liberal and democratic societies, the â€Å"Heralds of Democracy†? People fear what they don’t understand. Islam is this â€Å"other† and the media and politicians play on this. The Muslim immigrant populations don’t help either because they themselves are in a transition phase. They are trying to find a way to live with an Islamic background and Western ideals. Some see total assimilation as an answer others find a compromise and yet others turn to radicalism. This struggle has been going on since the mid-19th century, between the â€Å"West† and Islam. Some essentialists like Huntington and Fukuyama, see this as the next power struggle for the â€Å"West† after the fall of the Soviet Union, â€Å"The Clash of Civilizations†. According to some 9/11 and other terrorists acts just prove this theory, however even though there are radicals, they are in the minority. The majority of Muslims don’t have problem with the â€Å"West†, most even are pro-Western, they support democracies and liberal views. Maybe, it is not the same as Europe or America but they are trying to find the middle ground and negotiate between the two. This is no different for the immigrants in France or Netherlands. Ahmet Yukleyen in his study of social movements in the Netherlands has focused on Turkish immigrants and the role religious movements have played a role in their lives. His studies show that there is not one Islamic front in Europe or a â€Å"Euro-Islam† as some have supported. Even though the Islamic community is one ummah, they all interpret and practice Islam in slightly different ways. The fundamental tenets are the same, but Islam is flexible according to time and place; taken from a historic or even contemporary perspective this can be seen. Euro-Islam† was supposed to be the liberal Islam for European standards, the Islam with lacite, secular Islam. This view has been supported by pro-assimilates, like France. However, this didn’t turn out to be true because it would have compromised too much from Islam, it would no longer be â€Å"Islam†. What happened, like in the Netherlands, was th at people joined different social/religious movements and institutions. This was truer for second and third generation Turks, who felt the need of religion more than Turkish nationalism in their lives. They saw themselves as Dutch, liberal and democratic in their views but still Muslim. Yukleyen, names a few organizations, like Milli Gorus, the Gulen Movement, and Suleymanli. Each movement represents different set of ideals but each represents a facet of Islamic life in Europe. It also shows that Muslims can negotiate between European and Islamic ideals, finding a niche their society. Not only that, but by having dialogue and inter-faith organizations an atmosphere of tolerance and multiculturism can flourish. Maybe, dialogue and negotiation is the answer to the dilemma facing Europe and the Muslim immigrants, the inability to understand one another. Work Cited Coenders, M.

Lebanon War 2006 free essay sample

The Lebanon War of 2006 began on July 12th, when Hezbollah launched a rocket attack on Israeli military positions stationed near the border between Lebanon and Israel. In the minutes during the ensuing chaos, Hezbollah militants crossed the border into Israel, and kidnapped two Israeli soldiers who they intended to use as collateral in a prisoner exchange with Israel. The war lasted until August 13, 2006, at which point the United Nations intervened. During the war, both sides targeted civilian areas, resulting in the deaths of over one thousand civilians and the displacement of thousands more. In an account of the 2006 Lebanese War published by the Anti-Defamation League, Hezbollah militants are accused of launching rockets into Israel with the intention of harming civilians. Conversely, it is explained that the Israeli military targeted Lebanese civilian areas because Hezbollah has been known to operate out and live amongst civilian homes and stores. In addition, it appears that the author of the account places the blame upon Hezbollah for igniting the war against Israel by launching rockets across the border in the years following the departure of Israeli forces from Lebanon, after the Lebanese Civil War and the Israeli siege on Beirut. We will write a custom essay sample on Lebanon War 2006 or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The ADL reports that there were over twenty occurrences of attacks launched by Hezbollah militants on Israel between 2000 and 2006. The ADL, however, does not conclude its account of the events without addressing errors made by Israel. Many Israelis allegedly held their own government accountable for the destruction of parts of the country, not because the government retaliated against Hezbollah’s attack, but because â€Å"the military and country had been ill-prepared for the conflict and its soldiers ill-equipped† (ADL). Such accusations prompted the Israeli Prime Minister to order a commission of inquiry to address the accusations. In 2007 and 2008, the Winograd Commission announced that questionable decision making had taken place during the war by Israeli government officials. Rasha Salti’s personal account of the 2006 war from the perspective of a citizen living in Beirut makes no mention of Israel’s self-proclaimed guilt, however. Her compilation of notes written during the war instead portray the violent attacks and practical demolition of Lebanon – a country that had only recently managed to rebuild itself after the conclusion of the fifteen year civil war in 1990. Her frustration about the situation and her devastating accounts of civilian casualties during the 2006 war blame only the Israeli military and government because of the brutal force and destruction used against Lebanon. Salti even makes reference to the abduction of the Israeli soldiers, and criticizes the Israeli government for overreacting and launching a war against Lebanon in retaliation. The ADL’s description provides factual data that is not included in Salti’s â€Å"siege notes†, and alternately the â€Å"siege notes† provide a personal account of the war that any reader would be able to relate to and identify with. Despite reporting upon Israel’s Winograd Commission, the ADL clearly maintains the perspective that Hezbollah functions as a terrorist organization and was at fault for the 2006 Lebanon War. Salti, on the other hand, conveys a clear message about Israel’s vicious military and menacing government. The comparison of documents such as the ADL and Salti accounts of the 2006 Lebanon War illuminates the importance of collecting multiple sources of information before drawing conclusions about any historical event.

Free Essays on Political Landscape From 1850 To 1860

Leading up to and even during the 1850’s, political parties within the union grew tense on the issue of slavery. In the text the author quotes Calhoun as saying â€Å"the cords holding the Union together had already begun to fray.† This is a great description of the growing animosity between the numerous party members. The most devastating blow to the Whig party was brought by the Kansas-Nebraska Act which was put forward by Stephen Douglas and repealed the Missouri Compromise and allowed popular sovereignty in the new territory of Kansas. With the split of the Whig party, some Northern Whigs joined the new American party which stood for serving the â€Å"patriotic cause of the Union.† Other Northern Whigs joined independent Democrats and Free Soilers arguing in opposition to slavery and forming what is later known as the Republican party in 1854. In 1854, at their first national convention, Republicans sought out John C.

Roman Emperor Septimius Severus

Roman Emperor Septimius Severus Severus came to power by disposing of rivals with a better claim to power than his own. His immediate predecessor was Didius Julianus. Septimius Severus died peacefully, leaving, as joint successors, his sons Caracalla and  Geta. Dates April 11, A.D. 145-February 4, 211 Reign 193-211 Places of Birth and Death Leptis Magna; Eboracum Name Lucius Septimius Severus Augustus (Severus) Occupation Ruler (Roman Emperor Septimius Severus was born in Africa, at the Phoenician city of Leptis Magna (in Libya), to a presumed equestrian (wealthy) family with consuls in it, on April 11, 145, and died in Britain, on February 4, 211, after reigning for 18 years as Emperor of Rome. Family Parents:  P. Septimius Geta, (equestrian) and Fulvia Pia Wife:  Julia Domna Sons:  Bassianus (Caracalla) (b. 188); Geta (b. 189) Following the murder of Pertinax, Rome supported Didius Julianus as emperor, but as Severus entered Rome having been declared emperor by his troops in Pannonia on April 9, 193 [DIR], the supporters of Julianus defected, he was executed, and soon the soldiers in Italy and the senators supported Severus, instead; meanwhile, troops in the East proclaimed Syrias governor, Pescennius Niger, emperor, and the British legions, their governor, Clodius Albinus. Severus had to deal with his rival claimants. He defeated Pescennius Niger at the A.D. 194 Battle of Issus not to be confused with the battle in 333 B.C., in which Alexander the Great defeated the Persian Great King Darius. Severus then marched into Mesopotamia, where he set up a new legion and declared war on Roman emperor Clodius Albinus. Even with the legions of Britain, Gaul, Germany, and Spain, behind him, Albinus still lost to Severus in 197 near Lyon [see Lyon Museum], and committed suicide. The reputation of Septimius Severus changes with the times. Some consider him responsible for the Fall of Rome. According to [virtual-pc.com/orontes/severi/MoranSev193.html, 6/29/99] Jonathan C. Moran, Gibbon blamed Severus for the changes that led to turmoil and ultimate decay in Rome. The De Imperatoribus Romanis entry on Severus explains the charge: by giving greater pay and benefits to soldiers and annexing the troublesome lands of northern Mesopotamia into the Roman empire, Septimius Severus brought increasing financial and military burdens to Romes government. His reign was also considered bloody and according to the Catholic Encyclopedia, he may have been involved in the murder of his predecessor, Pertinax. The Catholic Encyclopedia also says he persecuted the Christians and forbade conversion to Judaism and to Christianity. On the other side, Septimius Severus restored stability to the Roman Empire. He improved performance and increased morale by making (expensive) changes in the military and praetorian guard. He restored Hadrians Wall and was involved in other construction projects. He also played the part of the traditional emperor: He reformed the grain supply for the city of Rome.... He put on games... for the people to keep them diverted and on his side. He freed his friends from debt and gave donatives to the soldiers and people. He also heard lawsuits.... Severus also began appointing his own men to the senate, one the emperors traditional prerogatives.- [www.virtual-pc.com/orontes/severi/MoranSev193.html#1, 6/29/99] Severus and Traditional Auctoritas Print SourceSeptimius Severus: The African Emperor, by Anthony Richard Birley Also, see Historia Augusta - The Life of Septimius Severus Septimius Severus and the Severan Emperors Septimius Severus and his successors were known as Severan Emperors Septimius SeverusCaracallaGetaEmperors Pertinax and Didius JulianusRoman Emperors Timeline 2nd CenturyRoman Emperors Timeline 3rd Century Ancient Sources on Septimius Severus HerodianHistoria AugustaDio Cassius

Interior Design of the Alhambra Essay Example | Topics and Well Written Essays - 2250 words

Interior Design of the Alhambra - Essay Example There is an attention to detail and patterns to where intricate forms are made. In addition to the interior aspect, it has a massive interior space but even so, the smallest corner has great significance in the entire presentation of the building. It then has these momentous domes that are loaded with art work and glass that allow light to enter the space making it a different place in different times of the day. I will now present a detailed description of the Alhambra and the meaning of its designs. The "red fortress" or the Alhambra is the only most significant and most conserved Arabian palace. The Alhambra is built by Moorish kings during the 12th and13th centuries and is located in the southern part of Spain. Its chief glory is its exceptional ornamentation. The name also refers to the color of the mountain to where it is built. The palace is an ensemble of exquisite artistic designs that can be attributed to the following inspirations such as religion, nature, music, culture, important personalities, and the foreign influences. It is a genuine expression of the once prosperous Moorish civilization and its architecture in Spain. The interior of the structure is decorated sumptuously with impressive examples of the honeycomb and stalactite-like vaulting1 of roof or dome which are eminent and typical of Islamic style of decoration. The famous beauties of the palace are: The Gate of Justice, The Court of Alberca; The Court of Lions with its alabaster basin peeling diamond drop s; The Hall of Ambassadors; The Tower of Canaries; The Court of Myrtles; The Hall of Justice; and several gardens, fountains, panoramas, chambers, towers, and balconies. Little and beautiful patterns containing vines and Arabic characters are interwoven into a structure of red, black, blue, and gold unspeakable richness. Decoration is simply defined as the act or process of putting ornaments to beautify, adorn, or enrich a place. Once all these concepts are implemented in the interior of a building or a structure, it now becomes interior decoration. In the Alhambra, the embellishment or decoration within the palaces epitomized the vestiges of Moorish dominion within Spain. The seclusion with the rest of the Islam, and the commercial and political relationship with the Christian kingdoms also influenced in the concepts on space; columns, muqarnas and stalactite-looking ceiling decorations, are visible in several chambers, and the interiors of numerous palaces are decorated with arabesques and calligraphy. Muqarnas is an Arabic word that illustrates a traditional element distinctive to Islamic architecture. They are small niche-like components that are combined with each other in successive layers to enclose a space and produce surfaces rich in three-dimensional geometric compositions.2 It is a unique Arabic/Islamic space-enclosing system used for the decoration and ornamentation of domes, minarets and portals. This type of design is often applied to domes, pendentives or devices used allowing the placing of a circular dome, cornices, squinches and the underside of arches and vaults. Indeed, the Alhambra is one of the olden structures to use the muqarnas. At the same time, arabesque is an elaborative application of repeating geometric forms that often resonates the forms of plants and animals. Usually this type of design is found in the walls of mosques. Arabesque designs found in the Alhambra did
