1) MODERN TIMES is a very well prepared movie that describes the miserable conditions of humar resource during the period of industrialization era or machine age worlwide. It is a mix of social drama and comedy. The content is presented in a satire. How did people survived the great depression of the world is being documented here. The conditions werre miserable like acute shortage of work, factory closings, labor strikes and political unrest etc. It is a symbolic representation of what happens to a human being caught up in the mechanical bureaucracy of the intellectual state. 2) Economically it could be understood that what miser situations could depression bring up. Food and jobs comes hard in hand. To which a labor is convict to do under skill jobs as well for survival. At the time of the great depression Americans had to fight for what little they had, and as the movie showed many people went hungry. Modern Times looks toward the future, but not with enthusiasm. Often described as a satire of the machine age, It has in fact a broader theme: the dehumanizing effects of many aspects of modernity, including industrialization, bureaucracy, urbanization, and law enforcement. 3) From the movie a prospect employee should not forget about the social ills and failings of own day even if present age is seems far better than that was shown in the film. A dilbert-like early scene shows the Tramp trying to take a break during work hours in the washroom — only to have a big-screen image of the boss’s head suddenly appear on the washroom wall and order him to quit stalling and get back to work. Modern audiences watching this scene may reflect ruefully on the everyday reality of electronic surveillance in the workplace. Now, obviously there’s nothing new about widespread poverty and want, but unemployment as we know it today is a comparatively recent development — a byproduct of the modern workforce economy that requires everyone to \"get a job.\" 4) The major ethical dilemma consists whether out of povertty stealing is right or wrong. However this movie glorifies the struggle of the poor rather than vilifying them for stealing food to survive. By glorifying the struggle the movie takes on yet another social issue: when the poor steal to eat it is not criminal, just survival.

An ion is an atom that has a charge. These charges can be postive or negative and depend upon the amount of electrions lost or gained. Ions are formed when they gain or lose an election ( a change in valence electrons) An example is Li+. That is a Lithium atom with a positive charge, it has lost one electron. A cation is a positively charged ion. Li+ An anion is a negatively charged ion. F-. A Fluorine atom that has gained an electron. A polyatomic ion is a multi-atom molecule with a charge. Such as ammonia NH4+. Solution An ion is an atom that has a charge. These charges can be postive or negative and depend upon the amount of electrions lost or gained.

Acids are substances that form hydrogen ions, H+(aq), when dissolved in water In acid solutions there are more H+ ions than OH- ions. Bases which are soluble in water are called alkalis e.g. NaOH sodium hydroxide, KOH potassium hydroxide or Ca(OH)2 calcium hydroxide. Bases which are water insoluble include CuO copper(II) oxide, MgO magnesium oxide. After a neutralisation, the salt solutions consist of a mixture of positive and negative ions (and their names are in the salt name!) e.g. sodium chloride (NaCl) is a mixture of Na+ and Cl- ions, calcium chloride (CaCl2) is a mix of Ca2+ and Cl- ions; magnesium nitrate (Mg(NO3)2) is a mix of Mg2+ and NO3- ions, aluminium sulphate (Al2(SO4)3) consists of Al3+ and SO42- ions etc. You can test for chloride ions by adding a few drops of dilute nitric acid followed by a few drops of silver nitrate solution. If chloride ions are present you will see a white precipitate of silver chloride. However, chlorine water itself will contain chloride ions as chlorine in aqueous solution disproportionates to form chloride and chlorate(I) ions. Cl2 + H2O --> Cl- + ClO- + 2H+ Testing for the presence of nitrate via wet chemistry is generally difficult compared with testing for other anions, as almost all nitrates are soluble in water. In contrast, many common ions give insoluble salts, e.g. halides precipitate with silver, and sulfates precipitate with barium. The nitrate anion is an oxidizer, and many tests for the nitrate anion are based on this property. Unfortunately, other oxidants present in the analyte may interfere and give erroneous results.

ANSWER: 1.\"Apocalypse Now\" film overall form: It is the height of the war in Vietnam, and U.S. Army Captain Willard is sent by Colonel Lucas and a General to carry out a mission that, officially, \'does not exist - nor will it ever exist\'. The mission: To seek out a mysterious Green Beret Colonel, Walter Kurtz, whose army has crossed the border into Cambodia and is conducting hit-and-run missions against the Viet Cong and NVA. The army believes Kurtz has gone completely insane and Willard\'s job is to eliminate him! Willard, sent up the Nung River on a U.S. Navy patrol boat, discovers that his target is one of the most decorated officers in the U.S. Army. His crew meets up with surfer-type Lt-Colonel Kilgore, head of a U.S Army helicopter cavalry group which eliminates a Viet Cong outpost to provide an entry point into the Nung River. After some hair-raising encounters, in which some of his crew are killed, Willard, Lance and Chef reach Colonel Kurtz\'s outpost, beyond the Do Lung Bridge. “This is the end, beautiful friend… This is the end, my only friend, the end Of our elaborate plans, the end Of everything that stands, the end No safety or surprise, the end I\'ll never look into your eyes...again The End...” 2.Primary Techniques in Apocalypse Film: Runtime 3.Techniques: Although many scenes are unusual since the movie begin an unusual journey in the midst of an alien world, some of the scenes still stand out.One of the most effective techniques used in the movie is the usage of very long dissolves. Many scenes are dissolved on each other until they become a montage of their own in one shot itself and say something completely distinct from their individual meaning. This was used in the beginning of the movie, in the middle when the journey enters the final realm and in the end again giving the seemingly untying themes a thematic unity. Many times, the war is superimposed on Willard’s face as if he is living it & re-living it long after it has gone or perhaps long before it has happened...! (Slow Dissolves) When the boat is finally entering the waters of Cambodia and we know that it is a point of no return for this boat and especially Willard, a few images are superimposed on each other to create a heightened sense of an altered reality. The boat is passing through the gates of the underworld and right in the center of all of this is Willard trying to look, listen and comprehend. (Slow Dissolve To Gates Of Hell1, Slow Dissolve To Gates Of Hell2, Slow Dissolve To Gates Of Hell3, Slow Dissolve To Gates Of Hell4, Slow Dissolve To Gates Of Hell5) Another highly unusual shot worth mentioning is Visual Constancy Or Horror. When I saw this shot, I thought that if my eyes did not have visual constancy and did not fill in Willard’s body automatically, the body-less face in this scene would be part of the true horror genre...! 4.Techniques and patterns: a)Lighting: Lighting is the key element in the film. Along with fogs and shadows. The general lo.

By the way, sweating/panting is NOT a means of getting rid of excess water; it is a way of getting rid of heat. We do this because of the process of evaporation. In changing from liquid to vapor, the water absorbs heat from the surface on which it is laying. Actually, most organisms do not want to get rid of excess water; they need to conserve it, but on very hot days animals \"spend\" the water to achieve the cooling. 6.
