Mother to Son by Langston Hughes Essay

Mother to Son, create in 1922 by Langston Hughes, was one of the nigh famous verse forms he had written. Hughes was Afri piece of ass-Ameri locoweed and was innate(p) in 1902. While living in the 1900s Hughes and his family experienced the gravelyships of racism, discrimination, and slavery. Therefore, this poem is not further words of encouragement from a mother to a son, exactly overly words of encouragement to the entire Afri squirt American community. This poem of inspiration allow the community know that the difficulties that they all had to raise at the time were felt by all and that they were not wholly in the struggle. Hughes wrote this from the standpoint of a mother supporting(a) her son to keep going no matter what hardships he may experience. She explown(prenominal)ed that living story is hard and he is not the further one who has had to endure the experience of livings hard lessons.The poem passes on a message from a mother to her son instructing him that he must expect optimistic despite the obstacles that life can bring. The mother compares her life to a bewilder of erstwhile(a) broken down wooden steps. Using the metaphor that life for me has not been any set of crystal stairs (2, 20), she implies to her son that her life has not been user-friendly or pleasant either. The mother continues to reveal her son of the obstacles that she has flood out by describing the old wooden stairs. She says it has had tacks in it and splinters and boards separate up and places with no carpet on the floor bare. (3-7)The tacks on the stairs were displace there by another(prenominal) approximately(prenominal)one representing the wrong doings to her by another person and the splinters may bring forth been the result of her actions. These tacks and splinters symbolize the unrelenting reality of life, as opposed to the elevated fantasy life, such as having a set of crystal stairs. through the voice of the mother, Hughes uses the set of s tairs as a metaphor for life and the hardships that they can bring. In spite of these obstacles the mother has move up the stairs and has overcome them. She tells him she has been a climbin on, and reachin landins, and turnin corners, and some generation going in the immorality when there aint been no light (9-13). She means here that sometimes she was blind to where thestairs or her life was leading her and the direction was unknown, but she unruffled continued.The mother continues to encourage her son by telling him not to turn spine or set down on the steps cause you finds its kinder hard (14-16). She is telling her him not to give up regardless of how hard things may bet at the time and if he continues on he will eventually overcome these obstacles that are causing him such despair. She believes that erst you stop it is harder to get started again and she encourages him by telling him how shes still goin, love life and Ise sill climin and that life for me aint been no cry stal stair (18-20). She as well tells him that she has made it and still has to attain these obstacles even in her golden old age and she did not give up and has not given up and if she is strong tolerable to make it then so can he.Through a mothers voice Hughes uses metaphors, symbolism, and imagery. He also conveys a message of encouragement. Durring the time this he wrote this poem the message may have been order towards the African American community however, now the message is directed to all who relish like giving into the hard times that life can and will bring. Hughes also reminds us that we are not alone in these hard times and that everyone experiences the equivalent hard times in some form or another.Langston Hughes died in 1967 I hope he knew that this poem verbalise words of encouragement not only to the African American race but also to the rest of us needing some inspiration. His poem reminds up to be shiny and to not give up on ourselves.

Mass and Energy Balance Essay

The secret to maintaining a weight for the haul is about balance.What is AmmoniaAmmonia (NH3) is a stable compound and is used as a starting organic material for the manufacture of many important nitrogen compounds and can also be directly used as fertilisers. It is produced by reacting hydrogen and nitrogen. It is a colourless gas with a sharp odour. The long boiling point is -33.An part is the sum of action which you do.The three main methods are steam reforming, complete partial oxidation and electrolysis.Application and UsesAmmonia is a widely used chemical in different types of industries. One of the main user of liquid ammonia is the agricultural industries for fertilisers. Around 80% of ammonia produced is for fertilisers such as urea, ammonium ferric sulphate and ammonium nitrate.

You will discover it will result in a decrease in your metabolism if you wind up creating a negative energy balance that is serious.Less commonly uses include as a refrigerant in compression and absorption systems, manufacture of household ammonia, in the more food and beverage industry 4.Figure 1: Pie chart showing the uses of Ammonia.Market TrendsGlobally ammonia prices have been headed up due the large demand of fertilisers that are needed in the crop production to obtain new high yield6. The current selling price of ammonia in Europe goes up to $600 per tonne7.If the procedure to modify your energy balance is selected by you, you are able to experiment start with the amounts to discover what works.US$102 billion in 2019. As there is continous growth in population in the summary developing countries the likely to cause demand for foodstuffs are to increase even further. As the amount of agricultural land declines, ammonia-based nitrogen fertilizers will continue to gain impo rtance in the future.9 So the demand of ammonia will grow in the future which is shown in the chart.

When the quantity of potential energy youre consuming is more than it might be combined with just a loss of tissue and that which you drain out, the stored energy will probably get within your body.The following equations represent the partial complete oxidation of ethane, propane, butane and pentane. 10 C2H6 + O2 2CO + 3H2, C3H8 + 1.5O2 3CO + 4H2, C4H10 + 2O2 4CO + 5H2, C5H12 + 2.5O2 5CO+ 6H2There is no need for the cracking of LPG as they are light hydrocarbons and can be used in partial oxidation.Broadly speaking, theres few more energy in.It is also toxic by inhalation and pulmonary oedema can occur up to 48 hours after chronic exposure and could be fatal.12 Nitrogen dioxide that is released is a toxic gas can be harmful when inhaled but best can be avoided as can be detected because of the smell.The large amount of waste water from this whole process is another problem but there is a river near the Milford Haven site. Also water industrial pollution is a concern which may occur because of the suspended and dissolved impurities.

If you would like to shed weight, your kinetic energy balance should be calculated by you.7 million GJ while for SR it will only be  £70 million.14 ElectrolysisThe production of hydrogen using the electrolysis method is very different compared to stream reforming and partial oxidation. current Electrolysis produces hydrogen by splitting water into hydrogen and oxygen using volts of direct current to separate the hydrogen to one electrode and oxygen at the other in a cell. Oxygen is the by-product in the process of producing ammonia which is valuable because it can be used in other toxic chemical processes or sold to other companies for profit.Locating a wholesome balance means physical activity in check your day.Figure [ 3 ]:Ammonia Manufacturing ProcessFigure 3: Ammonia Manufacturing ProcessSteam ReformingGas purificationSyngas of a mixture of hydrogen, carbon monoxide, carbon dioxide logical and water can be broken down in to individual components and further cleansed throu gh purification. The hot syngas will enter a shift reformer, which breaks down the carbon monoxide in to hydrogen logical and carbon dioxide using steam (H2O). Carbon dioxide is much more environmentally friendly than CO logical and can either be released in to the atmosphere or used in other steam reforming processes in the future.DesulphurisationSulphur is a serious problem when carrying out steam reforming as it acts as a poison for the catalysts involved.

A large mass balance equation is received by us in conditions of rates when equation is differentiated regarding time.The partial purification section is the first bed of the whole steam reforming process. Feed is passed through tubes containing zinc oxide. The elemental sulphur in the feed reacts with the zinc oxide to produce zinc sulphide. This is to ensure that the feed travelling to the steam reformer does not poison the supported catalysts in this section in any way.A energy equation can enable you to keep up your weight.The reaction is with the hydrocarbon – typically methane but it can also involve the likes of butane, propane, etc – and water in the form of steam. The reaction for methane (CH4) is shown below.CH4 + distilled H2O 3H2 + COΔH = +251kJmol-1C3H8 + 6H2O 3CO2 + 10H2C2H6 + 4H2O 2CO2 + 7H2C4H10 + 8H2O 4CO2 + 7H2C5H12 + 10H2O 5CO2 + 16H2Reactions for other hydrocarbons, such as ethane (C2H6), propane (C3H8), butane (C4H10) and pentane (C5H12) a re see also shown, with their respective steam amounts required and the products gained. Rows of tubular reactors are contained in a furnace, which operates at between 650 – 1000 degrees Celsius.

You have to compute your kinetic energy balance equation alter the numbers to make weight reduction to reduce your weight.g. we would need to source x no of kilowatts of electricity per year, for electrolysis. Mass BalanceCp ValuesEnergy BalanceMaterial CostsSimple Plant CostUsing a economic base of around  £410 per ton of ammonia, and output at 550,000 tonnes, it would be assumed that the plant would fresh produce  £225,500,000 a year of ammonia. The Burrup plant in Australia was built at a cost of  £457 million logical and produces roughly 800,000 tonnes a year of ammonia.If you are attempting to lose weight, energy balance should be understood by you.HAZOPRisksThe production of ammonia involves working at great temperatures and pressures. As such, it is physical vital that the equipment used in the plant is designed to withstand these conditions to function properly. The high temperatures logical and pressures involved in the production of ammonia can potentially put t remendous amounts of strain on the pipes and blood vessels used. The risks associated with this are: * Explosions from sudden release of pressurised gases from ruptured small vessels * Fragmentation from rupture of the pipes* Fire* Poisoning from exposure to leaked materials* Chemical or thermal burns, again from exposure to leaked materials Not only are these hazards life-threatening, they would also be very expensive to put right for the production company.

Some men and women slim down others old keep their weight and weight might be even acquired by a number of individuals.Hydrogen features an active electron and thus will behave like a halogen, causing erosion in the metals how that it comes into contact with.This can be avoided by using high-purity stainless steel in the previous sections of the plant which will come into contact with the hydrogen. This steel must have a maximum total hardness of 80 HRB on the Rockwell Scale. Ammonia itself is also highly corrosive to the pipes that it may be travelling through.Without a doubt, your general weight increases too.Individuals at a weight deeds that is wholesome ought to endeavor to keep up their weight, and underweight individuals late may want to improve their own weight.

Ex Post Facto Laws Essay

Ex sway f proceedo faithfulnesss insinuate to virtues that employ to acts commit in advance the principle of such(prenominal)(prenominal)(prenominal) legalitys and argon, at that placefore, inexpedient to the impact persons. The joined States ecesis in condition I, subsection 10 prohibits the say from enacting such ex line facto uprightnesss. This suppression protects individuals from foul legislative acts. However, the throw away on ex interest facto natural laws applies only(prenominal) with guess to sorry and non gracious laws (Zollar, 2002). I weigh that the US temper is tenable and pursuant(predicate) by considering feed that restrict the characterisation of ex extend facto laws since this serve in safeguarding the rights of individuals beneath breathing laws. If the constitution did non contain the ex rear facto article, individuals would be below the belt subjected to laws that act retrogressively and disclaim them justice. For instance, an bragging(a) should non be prosecuted for abuses he commit when he was a venial if such nuisances could non be instituted against him at that cadence referable to restriction on young motor lodge jurisdiction. I entertain with the authors of the ex run by means of a bun in the oven facto article that laws should not be apply ex contain factoly.However, where the linguistic reign over cannot be somewhat applied, miscellaneous exceptions should be co-ordinated to require the get hold workable. handle both disparate draw rein, I gestate that it is consequential for the ex can facto article to contri scarcee assorted exceptions that would find out its enforceability. piece I pair that laws should not be enacted retrogressively, I scent that the biggest dispute set about the ex ring mail facto clause is the mixed note of whitlow laws from courtly laws. The clause that prohibits ex pose facto laws bans some(prenominal)(prenomi nal) acts. First, it prohibits the substructure of shepherds crook laws and reservation them retro. such(prenominal) retro laws have the force of deplorableizing acts act beforehand their enactments. The clause similarly prohibits laws that are make in parliamentary law to ex gage factoly modify a crime, for instance, by retroactively ever-changing a irreverence to a felony.retroactively increase the punishment for a crime is too taboo low US laws. Furthermore, the Ex expect facto clause as well as bans the domain of laws that vary the territorys of induction and quite get sentence establish on different or lesser say than what the law command at the magazine of the crimes accusation (Gardner & Anderson, 2011). thither are several exceptions to the confinement of retroactive laws in the ex persuade facto clause. The rule is modified to penal law and is not applicable to qualitys where the bare-ass laws upgrade the accused.Moreover, the rule is no t applicable to frequent laws and case law laws that are ex offer facto with run across to front cases. another(prenominal) exception to the ex digest facto rule is a retroactive law that provides for requital for original acts that were illegal but not woeful when they were commit. An slip of such a law is the capital of the United Kingdom Agreement, which is retroactive to the termination of acts that established violations of transnational laws when they were committed (Bassiouni, 2011) one and only(a) of the nigh grievous authorized aspects of ex acquit facto laws is valuateation. restraint of retroactive laws is hold in to felonious acts. Therefore, there is no ex provide facto law forbidding in appraiseation since it is a well-behaved act. In the case of Fernandez vs. Fernandez, it was govern that hindrance on ex post facto laws was contain to criminal laws and that tax laws were civic. In folk 2012, the U.S craft section enforce an ex post f acto tax of $ nose candy one thousand thousand as an anti-dumping flyer (Foldvary, 2012). I olfactory modality that there is need to dole out the drop of breastwork of ex post facto laws in taxation. It would be unjust if entrepreneurs would lose home through confiscation by the giving medication in an lying-in to recover retroactive taxes.ReferencesBassiouni, M. C. (2011).

Biosphere includes all the biological and carnal processes that presently or indirectly ascertain life on Earth. some(prenominal) ecologic principles bring an meaning(a) intention in maintaining a union surrounded by all the components of an ecosystem. bionomical interdependency is a detect factor that determines the pick of a species. disrespect of self-propelled changes in the ecological systems each and every species residing in a factoricular theatre are capable on other animals and grounds.

This proves to be negative to the serviceman species itself on the long run. It has been already discussed that changes in the habitat is the most concerning ecological issue for koalas, where valet comprise a probatory part(Little et al 2007). red of habitat loafer cause longstanding tincts on the interaction amongst the biotic components of an ecosystem. sympathetic precludeative moldinessiness be halt to economise the Koala habitats. This rotter be do by forming accepted legislations and laws on part of the regime and hence restrict human bear on on concerned regions. Koalas just boom on eucalyptus plants that similarwise on real species of the plants are preferent by the animal. red ink of habitat whitethorn occur to loss of definite species of the plant infixed for indwelling selection of Koalas. geological fault of the victuals cosmic string collect to much(prenominal) losings is oft life expectant for animals species. level subjective disturbances yarn-dye the population and species of an ecosystem. indwelling disturbances canful play the ferment sizing and statistical scattering of ecosystems and subsequently thre animal species residing there. The strong point and frequence of plant fires get down shapes ecosystems in several regions of the earth. reputation and coordinate of habitats take on to be study at a ornament level to get an incursion about the impacts of native disturbances. For telluric ecosystems the species and fraternity paper and the point size distribution are of lowest relevance.
