Overview of Synthesis and Preparation Experiments

Overview of Synthesis and Preparation Experiments Introduction: As we know, Manganese is found in the first row of transition metal with the electron configuration [Ar] 3d5 4s2. Besides that, Manganese has different type of oxidation states when it appears as a compound and the oxidation state is from Mn(-III) until Mn(VII). So, we know that the compounds of manganese range in the oxidation number have a different of 10 electrons. In the experiment 1, we prepare tris(acetylacetonato)manganese(III), Mn(acac)3 by using manganese(II) chloride tetrahydrate and potassium permanganate act as oxidation agent to oxidise manganese(II) chloride to acetylacetonemanganese(III). Manganese(III) acetylacetonate is an one- electron oxidant. Manganese(III) acetylacetonate is high spin. It has also a distorted octahedral structure. This distortion is due to the Jahn-Teller effect. (Absolute Astronomy, 2009). The structure of Manganese(III) acetylacetonate is shown as below:- (Source: Tcieurope.com) The equation is as follow:- MnCl2 + 4H2O Mn(H2O)4Cl2 Mn(H2O)4] Cl + 2HC5H7O2 + NaC2H3O2 Mn(C5H7O2)2 + NaCl + HC2H2O2 4Mn(C5H7O2)2 + KMnO4 + 7HC5H7O2 + HC2H3O2 5Mn(C5H7O2)3 + KC2H3O2 + 4H2O Furthermore, bis(acetylacetonato)oxovanadium(IV) is also known as Vanadyl acetylacetonate, VO(acac)2. As we know, it is a blue green complex. bis(acetylacetonato)oxovanadium(IV) has a vanadyl group, VO2+. The vanadyl group is bonded to 2 acetylacetonate anions and the structure of the compound is as follow:- This complex can be made from vanadium(IV) or vanadium(V). In our experiment, bis(acetylacetonato)oxovanadium(IV) was prepared from vanadium(V) oxide and the equation is as follow:- V2O5 + 2H2SO4 + EtOH 2VOSO4 + 3H2O + CH3CHO VOSO4 + 2HC5H7O2 + Na2CO3 VO(C5H7O2)2 + Na2So4 + H2O + CO2 (Absolute Astronomy, 2009) Besides that, both of the acetylacetonato (acac) groups of bis(acetylacetonato)oxovanadium(IV) are able to be exchanged with organic ligands having coordinating atoms of different potentialities. (Maurya, 2003) Both Manganese(III) acetylacetonate and bis(acetylacetonato)oxovanadium(IV) are bond with acetylacetonate which known as ligand. The precursor for acetylacetonate is acetylacetone with formula CÂ ­5H8O2. However, acetylacetonate is an anion. It can bind to corresponding cation but it very hard to exist as a free ion in solution. In addition, Cobalt is a hard, gray metal. It has a proton number 27. Besided that, there are two types of cobalt ions namely Co2+ and Co3+. First, Co3+ ion is more weaker than the Co2+ ion. However, the complex ion formed with higher oxidation state is more stable. ( Â °zmir Institute of Technology, n.d.). So that, Cobalt(III) complexes are kinetically inert. Co3+ can undergo a process known as ligand exchange reactions slowly which compared to Co2+ complexes. The cobalt(III) complexes are usually in octahedral shape. In the experiment, chloropentaamminecobalt(III) chloride is being synthesized. The structure is as follow:- (Source: Chemicalbook.com) The complex is prepared by the oxidation of ammoniacal solution of cobalt(II) salts by using hydrogen peroxide. The formula is as follow:- Co2+ + NH4+ + 1/2H202 → [Co(NH3)5H20]3+ [Co(NH3)5H20]3+ + 3Cl- → [Co(NH3)5Cl]Cl2 + H20 ( Â °zmir Institute of Technology, n.d.) Materials and Methods: Experiment one, 5g of MnCl2.4H20 1.3g of NaC2H3O2.3H2O NaC2H3O2.3H2O Dissolved in 200cm3 of distilled water. 21cm3 of 2HC5H7O2 slowly added 1g of KMnO4 Present of two-phase layer Solution A added in with stirring Dissolved in 50cm3 of distilled water. 13g of NaC2H3O2.3H2O Solution B added in Solution A Solution B Dissolved in 50cm3 of distilled water. Heated with 60oC for 30 minutes Complex washed with acetone Solid complex filtered by suction Resultant solution was cooled with ice-cold water Experiment 2 Experiment 3 5 cm3 distilled water 4 cm3 concentrated H2SO4 10 cm3 ethanol Were added in. Recrystallise Results : For experiment 1, from the equation below, I can get the theoretical mass of the Mn(acac)3 solid complex by : Mn(H2O)4] Cl + 2HC5H7O2 + NaC2H3O2 Mn(C5H7O2)2 + NaCl + HC2H2O2 4Mn(C5H7O2)2 + KMnO4 + 7HC5H7O2 + HC2H3O2 5Mn(C5H7O2)3 + KC2H3O2 + 4H2O From the equation, we know that 1 mol of Mn(H2O)4] Cl = 1 mol of Mn(C5H7O2)2. So, 5 g of Mn(H2O)4] Cl = 0.0308 mol is also = 0.0308 mol of Mn(C5H7O2)2. From the second equation, 4 mol of Mn(C5H7O2)2 = 5 mol of Mn(acac)3 0.0308 mol of Mn(C5H7O2)2 = 0.0385 mol. So, theoretical weight of Mn(acac)3 = 0.0385 mol X 252.938 g/mol theoretical weight of Mn(acac)3 = 9.7381 g The following shows the method to get our experimental weight: Weight of Sample tube 14. 8180 g Weight of Sample tube + solid complex , Mn(acac)3 18.7785 g So, the experimental weight of Mn(acac)3complexes were 3.9605 g Percentage yield of Mn(acac)3complexes we get was = 3.9605 g / 9.7381 g X 100 % = 40.67 % Next, Magnetic moment of Mn(acac)3complexes were calculated as follow : m = 0.9278g- 0.8193g = 0.1085g Ro= -33 L = 2.4cm R= 1165 (paramagnetic) CBal = 1 X(g) = [CBal X L X (R-Ro) ] / 109 X m X(g) of Mn(acac)3complexes = 2.65 X 10-5 So, Mn(acac)3complexes are paramagnetic Interpretation of IR spectrum for complexes will be written in discussion. For experiment 2, from the equation below, I can get the theoretical mass of the [Co(NH3)5Cl]Cl2 solid complex by : Co2+ + NH4+ + 1/2H202 → [Co(NH3)5H20]3+ [Co(NH3)5H20]3+ + 3Cl- → [Co(NH3)5Cl]Cl2 + H20 From the above equation, 1 mol of Co2+ = 1 mol of [Co(NH3)5H2O]3+ 12g of Co2+ = 0.0504 mol So 0.0504 mol of [Co(NH3)5H20]3+= 0.0504 mol of [Co(NH3)5Cl]Cl2 Theoretical weight of [Co(NH3)5Cl]Cl2 solid complexes = 0.0504 mol X 250.433 g/mol = 12.6218 g The following shows the method to get our experimental weight: Weight of Sample tube 14. 9285 g Weight of Sample tube + solid complex , Mn(acac)3 22.3723 g So, the experimental weight of [Co(NH3)5Cl]Cl2 solid complexes = 7.4438 g Percentage yield of [Co(NH3)5Cl]Cl2complexes = 7.4438 g / 12.6218 g X 100 % = 58.98 % Next, Magnetic moment of [Co(NH3)5Cl]Cl2complexes were calculated as follow : m = 0.9264g- 0.8207g = 0.1057g Ro= -36 L = 2.1cm R= -41 (dimagnetic) CBal = 1 X(g) = [CBal X L X (R-Ro) ] / 109 X m X(g) of [Co(NH3)5Cl]Cl2complexes = -9.9338 X 10-8 So, [Co(NH3)5Cl]Cl2complexes are dimagnetic For experiment 3, from the equation below, I can get the theoretical mass of the [Vo(acac)2(H2O)] solid complex by : V2O5 + 2H2SO4 + EtOH 2VOSO4 + 3H2O + CH3CHO VOSO4 + 2HC5H7O2 + Na2CO3 VO(C5H7O2)2 + Na2So4 + H2O + CO2 From the above equation, 1 mol of V2O5 = 2 mol of VOSO4 2g 0f V2O5 = 0.011 mol = 0.022 mol of VOSO4 2 mol of VOSO4 = 2 mol of VO(C5H7O2)2 Theoretical weight of VO(C5H7O2)2= 0.022 mol X 264.94 g/mol = 5.8287 g The following shows the method to get our experimental weight: Weight of Sample tube 14.8445 g Weight of Sample tube + solid complex , Mn(acac)3 18.5818 g So, the experimental weight of VO(C5H7O2)2= 3.7373 g Percentage yield of VO(C5H7O2)2= 3.7373 g / 5.8287 g X 100% = 64.12% Next, Magnetic moment of impure VO(C5H7O2)2 complexes were calculated as follow : m = 0.8880g 0.8244 g = 0.0636g Ro= -34 L = 2.5cm R= 72 (paramagnetic) CBal = 1 X(g) = [CBal X L X (R-Ro) ] / 109 X m X(g) of impure VO(C5H7O2)2complexes = 4.17 X 10-6 So, VO(C5H7O2)2complexes are paramagnetic Magnetic moment of pure VO(C5H7O2)2 complexes were calculated as follow : m = 0.8947g -0.8211 = 0.0736g Ro= -33 L = 2.3cm R= 144 (paramagnetic) CBal = 1 X(g) of pure VO(C5H7O2)2complexes = 5.53 X 10-6 Discussion : Interpretation of IR spectrum for tris(acetylacetonato)manganese(III): Wavenumber (cm-1) Description of bands 2921.1 2959.7 -relative intensity : weak CH stretching of CH3 1593.9 1508.0 -relative intensity : strong -(C=C) stretching -(C=CH) deformation 1387.2 -relative intensity : strong -(CH3)- symmetric C-H deformation 1253.5 -relative intensity : strong -(C=C) stretching -(C-CH3) stretching 1016.8 -relative intensity : strong -(CH3) out-of plane bending 923.2 -relative intensity : strong -(C-CH3) stretching 777.0 -relative intensity : strong -(C-H)deformation 678.1 -relative intensity : medium/ strong -(C-CH3)stretching,(O=C-CH3) deformation -(Mn-O) stretching indicates metal-ligand bond 460.1 relative intensity : weak (C=C) stretching,(C-CH3) stretching -(Mn-O) stretching that also indicates metal-ligand bond Interpretation of IR spectrum for chloropentaamminecobalt(III) chloride: Wavenumber (cm-1) Description of bands 3258.0 -relative intensity : strong NH3 stretch 1576.2 -relative intensity : medium -degenerate asymmetric NH3 stretching 1307.8 -relative intensity : strong -symmetric NH3 angle deformation 844.9 -relative intensity : strong -NH3 rocking 487.6 -(Co-Cl) stretching indicates metal-ligand bond Interpretation of IR spectrum for impure bis(acetylacetonato)oxovanadium(IV): Wavenumber (cm-1) Description of bands 1556.8 1521.0 -relative intensity : medium (C=O) stretching -( C=C),(C=CH) stretching 1418.7 -relative intensity : medium -(CH3) deformation 1374.0 1357.6 -relative intensity : strong -(C=O) stretching -(CH3) deformation mode 1286.6 -relative intensity : strong -(C=C=C) stretching 998.2 -relative intensity : strong and sharp -stretching of V=O bond -it also indicates the metal-ligand bond. 1018.6 -relative intensity : strong -(CH3) rocking 936.1 -relative intensity : strong -(C-CH3) stretching -(C=O) stretching 798.6 -relative intensity : medium -(C-H) out-of-plane bending 685.9 657.2 -relative intensity : medium/ weak -(ring) deformation out-of-plane bending for: 609.2 -(ring) deformation Interpretation of IR spectrum for pure bis(acetylacetonato)oxovanadium(IV): FTIR is known as Fourier Transform Infrared Spectroscopy. This FTIR can be used to identify different types of chemical bond which is either organic compound or inorganic compound. So no two different compounds will have same spectrum. However, FTIR may cause destructive to our sample compare to magnetic susceptibility which is non-destructive. Besides that, magnetic susceptibility can be group by paramagnetic, diamagnetic and ferromagnetic. Paramagnetic substance is those attracted by strong magnetic field but those repelled by magnetic field are diamagnetic substances. Besides that, we can also confirm the shape by using magnetic susceptibility. The Cobalt ion to form Chloropentaamminecobalt(III) chloride has 6 electron in d orbital. Magnetic Susceptibility for chloropentaamminecobalt(III) chloride is -9.9338 X 10-8 and it is diamagnetic. Only the low-spin octahedral shape shows diamagnetic properties, so the shape of chloropentaamminecobalt(III) chloride is octahedral. Magnetic Susceptibility for tris(acetylacetonato)manganese(III) is 2.65 X 10-5 and it is paramagnetic. So the shape of tris(acetylacetonato)manganese(III) is octahedral. However we cannot determine whether is low-spin or high-spin in this situation because we are not calculating the pairing energy for the complex. In addition, there is only one electron in d orbital for vanadium ion of bis(acetylacetonato)oxovanadium(IV). Magnetic susceptibility for it is 4.17 X 10-6 and it is paramagnetic. Moreover, oxovanadium complexes act as insulin mimetics, nucleolytic and anticancer. To recognize insulin- mimetic complexes, a simple and fast in-vitro assay is developed. Besides that, an accurate assessment of the cells taken up of glucose, in-vitro assay with Ehrlich can be used. The oxovanadium complexes can cleave DNA without the present of hydrogen peroxide. Then, its nucleolytic efficiency is also greater but it is affected by the choice of buffer and pH. The oxovanadium complexes is also an anticancer agent against human ovarian cancer. Actually, I have acquired a lot of new knowledge among these three experiments. First, experiment one and two are easier to carry out compared to experiment three. This is because experiment one and two involved oxidation which Mn2+ was oxidized to Mn3+ ; Co2+ was oxidized to Co3+. Whereas experiment 3 involved reduction which reduced VO5+ to VO4+. At the beginning of each experiments, we heated up the sample in open air. It is easier to oxidize the compound than reduce the compound in the presence of oxygen. So, we need more time to heated the V2O5. During the first time of experiment three, I failed to get a blue color solid powder. This is because I heated the sample in the open air and I failed to control the heater. So, after the filtration process, I got a white solid powder. Therefore, I learnt from the mistake and during the second time I used reflux method. This time I can control the heating process well. The ethanol was not evaporated much. After filtration, I got quite a lot of blue solid powder. So, I knew that, for reduction process, we cannot heat the sample too quickly and heat too long. If we heated too long, most of the product will evaporate. Next, from the FTIR spectrum, I can observe that the spectrum from the first and third experiment are quite similar. This is because, the peak from the spectrum are mostly from the acetylacetonato (acac). However, spectrum from experiment two is quite different from other experiment because mostly the peaks come from Cl compared to other experiments. The percentage yield of the complexes from all the three experiment that I have calculate out was not so high. This is maybe due to the washing of the product with acetone, some of the product was dissolved and washed away. However, there are other factors which cause problem to our results. First, most of the heating plate we used cannot function well. I changed many heating plate during the experiment. Next, we have kept our half way done sample for more than 7 days. The results may not be so accurate anymore. Another factor maybe due to the volume and amount of the sample and other material we measure are not accurate. Our product may contain some impurities. However, some of the precaution was taken during the experiment. In these experiments, some of the chemical was corrosive and poisonous such as concentrated HCl and H2SO4. So, we poured the chemical carefully in the fume board. Next, before using any instrument, we read through the manual to understand the steps to function the magnetic susceptibility balance. We also taken down some important steps to function the FTIR spectrophotometer. I have asked some help from lab assistant on where to get the material for experiment. Conclusion The percentage yield for tris(acetylacetonato)manganese(III) is 40.67%, chloropentaamminecobalt(III) chloride is 58.98% and (acetylacetonato)oxovanadium(IV) is 64.12%. For tris(acetylacetonato)manganese(III), the peak for two Mn-O bond are at the region approximately 678.1 cm-1 and 458.3 cm-1. For chloropentaamminecobalt(III) chloride, the peak for Co-N bond is at 669.2 cm-1 while Co-Cl bond is at 486.2 cm-1. For bis(acetylacetonato)oxovanadium(IV), the peak for V=O bond is at 997.4 cm-1 region. Magnetic Susceptibility for tris(acetylacetonato)manganese(III) is 2.65 x 10-5 and it is paramagnetic. Besides, Magnetic Susceptibility for chloropentaamminecobalt(III) chloride is -9.93x 10-8 and is diamagnetic. For bis(acetylacetonato)oxovanadium(IV), magnetic susceptibility for impure complex and pure complex are 4.17X 10-6 and 5.53X 10-6 respectively. They are paramagnetic.

Oedipus Essay -- English Literature Essays

Oedipus The play Oedipus The King begins with the king and queen of Thebes, Laius and Jocasta. Laius was warned by an oracle that his own son would kill him and that he would marry his mother, Jocasta. Determined to reverse their fate, Laius pierced and bound his newborn sons feet and sent a servant away with him with strict instructions to leave the child to die on the mountain of Cithaeron. However, the servant felt badly for the infant and gave him to a shepherd who then gave the child to Polybus, king of Corinth, a neighboring realm. Polybus then named the child Oedipus (swollen foot) and raised him as his own son. Oedipus was never told that he was adopted, and when an oracle told him that he would murder his father and marry his mother he fled the city believing that the king and queen of Corinth were his parents. In the course of his travels, he met and killed Laius, thinking that the king and his servants were a band of robbers, and thus unwittingly fulfilled the prophecy. Oedipus then continued his traveling, and arrived at the kingdom of Thebes, which was plagued by a horrible beast, they called the Sphinx. The frightful creature frequented the roads to the city, asking travelers her riddle then eating them when they could not answer correctly. Oedipus answered the riddle the Sphinx presented him with correctly, saving the city and becoming a hero. Believing that robbers had killed Laius, and grateful to Oedipus for ridding them of the dreadful Sphinx, the Thebans rewarded Oedipus by making him their king and graciously giving Queen Jocasta as his new wife. The kingdom of Thebes was exultant, and the kingdom prospered under their new ruler, but again a grievous plague fell upon the city. The oracle was consulted to give an answer on how to rid themselves of the plague. The oracle proclaimed that Laius’s murderer must be punished in order to rid the city of the dreadful plague. Teiresias, a blind prophet was summoned to help the kingdom with their terrible calamity. He revealed that Oedipus was the murderer and that he was sleeping with his own mother. Oedipus did not believe Teiresias at first but slowly began to realize that it was true. In grief and despair of their incestuous life, Jocasta killed herself, and Oedipus, after learning of her death then blinded himself and was banished from Thebes forever, leaving Creon, his brothe... ...en back inside, Oedipus reared his ugly head. â€Å" Do not take them from me.† In which Creon answers, â€Å"Wish not to govern all, for what you ruled will not follow you throughout life† (Sophocles, 120). Throughout the play Oedipus displayed conflicting feelings as to whether he was more concerned for his people, who were going through a terrible time, or concern for his own past and future. In the prologue, when Oedipus first entered the scene he noticed his people were gathered around the alters and spoke to them with concern about what was going on. He acknowledged that the plague had taken its toll on his people and he assured them that he was taking action to remedy the situation. But then he turned it all around that he was bearing most of the burden, not his people, therefore asking for pity and being selfish. In my opinion, I do not believe that Oedipus was as concerned for his people in the end. He was too caught up in finding the truth about himself and then denying what was told to him. I thou roughly enjoyed this selection. Sophocles was indeed a wonderful playwright. He was able to create a story that will touch everyone in the way that Greek tragedies were supposed to.

The Approach Of Systems Thinking Commerce Essay

Over this century the attack of Systems Thinking has gained increasing attending in assorted social spheres, such as civilization, scientific discipline, general and human ecology, faith and economic sciences & A ; direction. System Thinking has taught us that it is non about faulting other people but to work together to happen a solution and to accomplish that there must be a good relationship, connectivity and interconnectivity. For any system to work efficaciously it is recommended that all parts be present and functional and must be connected to a proper manner. System believing in an Organisation chiefly depends on accomplishing negative information through openness and feedback, system believing besides plays a major function in administrations and aid to acquire rid of disfucntional administration, Successful organisations develop features and execute procedures that allow them to accommodate to restraints, menaces, and chances. For any administration grow and better that administration must so go larning administration and for it to work efficaciously there should be an effectual leading which will convey effectual alteration and originative thoughts to the administration. Learning organisation deter the outlook that it is merely senior direction who can and make all the thought for the full corporation and it hence encourages everyone ‘s thoughts are valued and amount that people can lend and it is non determined by place in the organisation.2.1 Quiz 1The embedding procedure, The following scenario has been experienced from my company.

FIG 3 INFORMATION SYSTEM BEHAVIOR Fig 3 above Tells us the information system in administration, Organisation should guarantee that its values are know by all employees and should populate by them, Trust within the administration leads to a good squad work with one end of accomplishing the best for the company. Policies and process should organize portion of day-to-day activities and should be communicated to all employees in an administration,2.3.1 LETTER TO THE BOARD OF DIRECTORSTitle: System Thinking Application in Organisation Background Many companies have failed themselves and some resulted in shuting down, No one of all time take clip to understand why this happens, Research shows that system thought does non be and Management does thing the manner they think. Most administrations do non run as a ‘whole ‘ but instead as a ‘part ‘ of the system. System Thinking Application Fig 1, 2 and 3 above illustrate Different application of the system thought, each and every figure will lend to the turning and development of the administration, Employees and Management will derive a batch of trust and apprehension of each other, to better our methods of alteration, hence, we need to understand more about what really governs people ‘s behavior. When no alteration occurs, it is the form of behavior that remains unchanged. Making the right thing means we have to larn how to see an administration as a system and understand the deductions of that position for what it means to pull off. Recommendation and Decision System believing when applied decently can alter the mentality of employees and it is recommended that all employees to be exposed to system thought and the construction should be such that employees must experience that they are portion of the administration, It is recommended that preparation should be provided to the employees to acquire the good consequences of system thought, Good communicating construction to be in topographic point and all informed of it, In decision, A learning administration produces a good consequences and increases working public presentation which leads to an addition in production. It is the Board determination to accept the application of System believing in this administration taking into history the benefit and the impact the system believing will hold in the administration.2.4 QUIZ 4What is Fractal – a fractal is any object or something or signifier created from repeated forms apparent at many degrees of graduated table. In my administration, I have noticed that a fractal quality take topographic point when we do the pre occupation brief [ where safety and occupation planning is discussed before the occupation can really get down ] and the Safety of people is ever emphasised and repeated, this is done to accomplish one end which is to hold zero first assistance and zero Loss clip hurts. Another Changes that I need to Implement is to accomplish Fractal quality is Cardinal regulations, These regulations are the regulations that can non be broken by anyone and should anyone interrupt anyone of the regulations, there will be a formal disciplinary for that person which might consequences to a serious misconduct These five cardinal regulations are as follows: Open, Isolates, Earth and/or bond and safety trial before touch Hook up at highs Be sober Have Permit to work I therefore see it necessary to warn co-workers each twenty-four hours about these five cardinal regulations.2.4 QUIZ 51. Angstrom 2. – 4B 3. Bacillus 4. Angstrom 5. Angstrom 6. Bacillus 7. – 4C2.5 QUIZ 6Undertaking Name: Renovation of Turbine Valves This is a undertaking that is presently busy with at my work topographic point Majuba Power Station Unit 4. Background In 2009 it was suspected that unit 4 Turbine Valve are damaged, this came after the machine was in a procedure of closing down after flushing extremum, The Operator who was in charge of the machine did non follow the shut down process and he was erroneously unfastened the control valve and allow H2O to travel through the Turbine, Water should non at any point go to the turbine as this could caused Quenching [ allow H2O to the turbine valves ] . The effects of Turbine extinction is a categorized as a catastrophe which cause the Rotors on the Turbine to flex and finally do the Turbine to vibrate, and since last twelvemonth therefore far the quiver has been so high, The ground for non making the fixs last when the incident take topographic point was the fact the system could non let Majuba to take the machine out for Outage due to the system constrains. The machine have been running at a lower burden since last twelvemonth and the hazard to run the machine with amendss was identified and all extenuation was put in topographic point to avoid farther amendss to the Turbine. Scope of work: Shut down the Machine Force cool the machine for 36hrs Erect Scaffolding [ Sub contract ] Remove lagging and cladding [ Sub contract ] Remove Turbine 4 Turbine valves Remove Turbine Two Rotors Send both Valves and Rotors for fixs at Alstom [ Sub contract ] Inspect and replace bearing no 1 and 10 if found damaged Collect both Valves and Rotors from Alstom Put back Turbine rotors Put back Turbine Valves Replace lagging and facing Dismantle Scaffolding [ Sub contract ] Perform Turbine tests, take reading and analyse [ Sub contract ] Start up the Machine The chief Contractor is Rotek Engineering Sub contractor no 1 Kaefer [ Scaffolding ] Sub contractor no 2 Alstom Power Services Entire costs for this Undertaking is R 13,000,000.00 Chaos Theory application This Undertaking was scheduled to get down on the 16th September and complete on the 29th October 2010, The chief Contractor is Rotek Engineering Sub contractor no 1 Kaefer [ Scaffolding ] Sub contractor no 2 Alstom Power Services After go toing The Da Vinci Institute classes on System Management, the tool used on the stuff was checked against my current undertakings as follows: So far Alstom has indicated that will be little alteration on the undertaking continuance as the range on the Valves and Rotors has increased after they have stripped and inspected the Vales and Rotors and that has a direct influence on the entire budget allocated, Rotek contractor together with Alstom revised the saloon chart every bit good as the WBS [ Non additive paradigm adopted ] which so showed a late completion day of the month of the 5th November 2010, as Eskom we do non desire to lose clip on the undertaking we so called up a particular meeting with the chief Contractor [ Rotek ] , The contractor was requested to direct a citation for an extra range submitted after the review was done and Eskom besides instructed the Rotek to acquire more resources and besides cite on that extra resources ( we applied control ) , The entire costs now has been increased to R 13A 850,000.00 which was non approved budget ab initio. We so as a squad called up a meeting with everyone involved, all were encouraged to work safe and put focal point on the work, the coverage / communicating construction [ D channel applied ] and organogram besides discussed with the squad and all understood the set up. Team members were motivated and were promised a braai every bit good as Game gift verifiers of R 150, 00 each should the undertaking be completed on clip. Everybody was asked to experience free on the occupation and to describe any insecure act and the suggestion box was placed on the floor for anyone with jobs on the undertaking itself including HR and Salary issues. In this undertaking non much alteration was applied to the solutions of mending the Valves and the Rotors as the recommendation was given by the industry and no other determination could be made as this constituents are non manufactured locally and no 1 knows much within South Africa. Presently the squad and everybody involved are happy and this is conformed by the committedness and dedication noted on the squad, this has led to a decrease in continuance of the undertaking by two yearss. The decrease in continuance has helped in costs decrease on the undertaking. Therefore Chaos theory in Project Management has taught us the followers: If a good planning and Execution is non done decently, that undertaking is a If there is no proper communicating in a squad, that is a formula for a catastrophe in a undertaking [ D channel plays a immense function ] The undertaking environment should be contributing for the squad to larn in order to maximize the usage of alteration.3.1 ANALYSE ELEMENT FROM STAKEHOLDER ‘S VIEWPONT3.1.1 Power Generation and Supply at Eskom This is an component that I will be discoursing and analysing, besides to place Operating, Transaction every bit good as Contextual Environment.

Eskom has a immense influence and impact on Electricity supply to its clients and besides has influence on its employees Members: Eskom Executive Committee Board members and employees on all Eskom divisions. Major constituents are all the electricity bring forthing workss and Coal and Gasses. Their relationship is that bring forthing workss requires Coal and Gasses to bring forth Electrical energy. Eskom has a dedicated staff that ensures there is continues supply of Electrical energy to Eskom clients, Currently Eskom stockholders are its employees every bit good as the Government, There are three trade brotherhoods viz. NUM, NUMSA every bit good as SOLIDARITY, Eskom chief clients are all Electricity users [ domestic usage ] , Mines, Hospitals and other neighbouring states, Current providers are Coal mines, gasses provider, Government appoints Eskom CEO and ensures that all authorities act are obeyed and followed by all Employers and Eskom is presently regulates by NERSA.

The initiation processes takes topographic point in the generator and the magnetic field are produced and Electrical energy generated. Then the generated power transferred to the Generator transformer which the measure up the Voltage from 22A 000Volts to 400kv, this 400kv is the sent to the grid and so national control controls the power distribution to all system webs and Eskom clients Eskom seeks new engineering each and every twenty-four hours for its nucleus concern of bring forthing Electricity at sensible monetary value and that is ever available, although Eskom do hold competent people and accomplishments but there is spread that needs to be closed due to the fact that people with so right accomplishments are go forthing the administration and there is skill keeping or development program in topographic point, Throughput procedure: Eskom produces a capacity of 4100 MW of Electricity per twenty-four hours, provided the full machines are on burden bring forthing electricity. Organizational procedure: Eskom have processs and Policies in topographic point which aid to run the concern efficaciously e.g. finance, engineering, quality, human resources, and selling are of import procedure considerations. Minimum demand – To be able to bring forth Electrical energy that is ever available at a sensible monetary value, Benchmaker: The best participants in the administration are all the Eskom employees and the employer who makes it possible produces this Electricity, Cost of selling is 150 Per Megawatt, Cost of Production is about R38m per Megawatt, Cost of developing about R12m, Cost of rank ( operating expenses ) is about R50m. 3.2.2 OBSTRUCTION ANALYSISBSTRUCTION ANALYSISFunctionStructureProcedurePowerDaily meeting are held where the production demands are discussed and actioned to relevant persons. Beginning of Power is at Management degrees and they are responsible for continues running of the Plant. Policies and process are clear and good defined, all people involved are cognizant of the procedure to be followed.CognitionEveryone is clear and knows precisely of what needs to be done as all are allocated with work for that peculiar twenty-four hours.

The system is in topographic point for all the divergence and control in conformity with NEC, feedback is required on specific agreed day of the months.WealthIn footings of Market viability, Eskom is still safe as the Market response rather good since there are no rivals ; The demand increases at a fast rate. Eskom beginning of money is on both Eskom ego net income every bit good as World bank where most of the loans are granted to Eskom. Although some the Generating Machines are acquiring old, The Machines still operates efficaciously and the demand is forecast 48 hrs upfront at the control Centre situated in Germiston and planned consequently.BeautyEskom vision of the coveted hereafter province that ‘Together constructing the powerbase for sustainable growing and development and to supply Southern Africa with dependable cost effectual Power ‘ At the present minute Eskom does non hold any insecurities and disaffection, South Africa chiefly dependant on Eskom to provide Electricity and the support is continues. There is a good Integration on Eskom ‘s stakeholders, The distinction exist when Government is loath to O.K. requested financess and when clients has to pay additions on ElectricityValuessThe Main hazards that Eskom faces are deficit of skilled forces, Insufficient power bring forthing machines to run into the increasing demand every bit good as support of the new undertakings Eskom value its employees and handle everyone with regard they deserve, The Group consists of different people coming from different background and Culture and everyone respects other chap ‘s civilization. Conflict Management processs are in topographic point to cover with any struggle arising.

Treat everybody with regard.3.4 CASUAL LOOP DIAGRAM3.4.1 Casual Loop Diagram Key FindingsThe undermentioned points indicate the chief country of concern on the above Casual cringle diagram in Fig 5: It is noted that high population addition electricity demand which in bend reduces the Supply of electricity The current procedure of bring forthing electricity has a negative impact on our environment as it causes pollution to the air. The effects of fouling the may every bit good mine workers where Cola is supplied may consequences to human deaths. It is an obvious instance that in winter season where there is no rainfall, the Eskom administration finds it hard to bring forth Electricity as there is immense deficit of H2O in the dikes and rivers. The more human deaths are experience in the industries is the more our population acquire reduced. It is true Eskom is lending to the Economy of this state because all concerns needs electricity to operates efficaciously Eskom as an administration opens occupation chances and allow people to develop in their callings within Eskom. It is besides noted that when the employees are given a opportunity to get cognition through surveies and research, they become more enlightening and increase that increases their accomplishments.3.4.2 Recommendation from the Casual Loop DiagramThe safety of people is a precedence and no production loss or net income can warrant the safety of people, it is hence recommended that the Companies should be more watchful and put systems in topographic point to guarantee that workers come to work safe and unrecorded work safe. It is recommended that administrations should hold a program in topographic point to develop its employees, this will convey good consequences in a long tally and will lend to the high net income of the administration as the employees will be more skilled and knowing which helps in increasing the company production.3.5 FRACTAL LIKE REQUIREMENTRefer to Quiz no 4 on page 103.6 BOARD MEMORANDUMRefer to Quiz no 3 on page 63.7 DecisionIn decision, whether we consider systems believing largely a new position and a set of tools, it has a power and a possible that one time we have been introduced, are difficult to defy. The more you learn about this challenging field, the more you will desire to cognize. In administrations, System Thinking has taught us that all sections should work together and incorporate to accomplish the best consequences, It has besides taught that although we need to cover with a alteration in our environment and learn to near as the ‘whole ‘ instead that a s ‘parts ‘ of the system.

The White And Black Women Essay - 1620 Words

Women of almost every race, age, culture, and social class have been oppressed since the beginning of time in one way or another and still are today. Both white and black women in the south were oppressed, but in drastically different ways. Free white women and enslaved black women were treated incredibly different, that much is quite obvious. This shows that the racism against black people of this time period is far more prevalent and distinctly more brutal that the sexism against women. Slavery negatively affected black women the most and while the economic benefit was significant to the male slave owners, their wives not only reaped the benefits of the wealth increase, but had less work in the home, were no longer the lowest level of social hierarchy, viewed themselves superior to northern women, and were envied by southern women not owning slaves. The elite white women of the south benefited and thrived from the slavery of women who were beaten, raped, and tortured. More male slaves were shipped over to America than female, because the demand for slaves was driven by labor intensive work needing to be done. Women were initially used to keep the men company and as domestic and field labors. After it was realized that the women could outlive the men and that in Africa these women were used to intense labor, more women were put to work in the fields as well.
