Dissolving Aluminium Chloride in Water

Dissolving Aluminium Chloride in Water A controlled variable is a variable that stays the same throughout an experiment such as: adding a specific amount of water to test tubes filled with different amounts of ammonium chloride. An independent variable is the variable that is changed during an experiment, e.g. different amounts of ammonium chloride added to separate test tubes in an experiment. A dependant variable is a variable that changes because of the independent variable, e.g. the difference of temperatures when the first crystals begin forming in the separate test tubes filled with different amounts of ammonium chloride. In this experiment the controlled variable will be 10mL of water that is added to each test tube filled with ammonium chloride. The independent variable will be the different amounts of ammonium chloride put into each test tube. The dependant variable will be the temperature of the first crystals appearing in the test tubes filled with different amounts of ammonium chloride that are dissolved in water. Ammonium Chloride Ammonium chloride is a substance which has the molecular formula NH‚„Cl and is highly soluble in water. It was first manufactured during the 13th century in Egypt and Europe and was originally known as sal ammoniac. It is used for a variety of purposes. In medicine it is used as an expectorant, which clears the phlegm from the bronchi, lungs and trachea area. It is also used as a component in dry cell batteries, an ingredient in cough medicine and as a dietary supplement to maintain pH levels. (See http://www.wisegeek.com/what-is-ammonium-chloride.htm . Last Updated March 13th 2013.) Solubility Solubility is when a substance is dissolved in a solvent such as water. This is then measured in g/100mL to calculate the solubility of that substance in the solvent, e.g. The solubility of 50g of Ammonium chloride would be shown as 50g/100mL of water. Solubility is a method used to calculate how much of a substance can be dissolved in a solvent. This method can be explained in three different ways: a saturated solution, an unsaturated solution and a supersaturated solution. (See also: Study on Chemistry 1, page 295-96.) A saturated solution is where no more solute can dissolve in the solvent at a specific temperature.  [1]  An unsaturated solution is where more solute can be added to dissolve in the solvent at a specific temperature.  [2]  However, a supersaturated solution is where an unexpected amount of solute can still be dissolved in a solvent at a specific temperature. A supersaturated solution can only be achieved (with difficulty) by changing the conditions of the saturated solution.  [3]   In this experiment, the substance is Ammonium chloride and the solvent is water and when mixed together, the Ammonium chloride dissolves. Repeating this with different amounts of ammonium chloride gives us the solubility of Ammonium chloride in g/100mL of water. When adding more ammonium chloride, the max amount of the substance that can dissolve in the solvent is discovered, this is called a saturated solution. If a specific amount of ammonium chloride that always dissolves in g/100mL of water is used, it is called an unsaturated solution because more of the substance can be added to the solvent, to dissolve. If the saturated solution of the substance is reached but more of the substance is added and surprisingly dissolves in the solvent, it is called a supersaturated solution. This experiment can consist of a saturated or an unsaturated solution because the solubility of Ammonium chloride in water is unknown. (See also: URLs displayed in bibliography with a * next to it) Solubility Curve Solubility curve is a graph of solubility vs temperature. Solubility curves are used to predict the maximum amount of a substance that can be dissolved in a solvent at a specific temperature. Solvents A solvent is a substance that is either a liquid, solid or gas that dissolves a solute to create a solution. The maximum amount of a substance that any solvent can dissolve depends on the temperature of the solvent, e.g. If water can dissolve a maximum of 30g of ammonium chloride at 50 °C, but the temperature was increased to 60 °C it could dissolve more of the ammonium chloride. There are two categories of solvents: polar and non-polar solvents. A polar molecule has two sides; one is positive and the other negative, also known as a dipolar molecule. Polar molecules have polar bonds, though some can have polar bonds but are non-polar molecules. This is because the polar bonds are arranged in a way that they cancel each other out. The overall polarity of a molecule depends on the direction of the bond dipoles in a molecule which is determined by the shape of the molecule. Polar solvents can have a small electrical charge because of the shape of the compound. A compound such as water has the hydrogen atoms at opposite angles of the oxygen atom. The hydrogen atoms can create a small electrical charge because of the direction of the bond dipoles, which is determined by the shape of the hydrogen atom. A molecule may mix in a polar solvent if it has a polarity of its own. Salt and sugar both dissolve in water easily because their molecules are attracted to the small electrical charges of water. Non-polar solvents dont have an electrical charge and cannot mix with a polar solvent. Polar and non-polar solvents use a dielectric constant to provide a rough measure of the solvents polarity. Dielectric constants are the electrical properties of a solvent using a capacitor, in which electrical currents pass through. Non-polar solvents are considered to have a dielectric constant of less than 15. The polarity index measures the ability of a solvent to dissolve different polar materials. The results of both these tests are used in a table of common solvents and in future can be used for identifying solvents in chemical processes. (See also: http://www.wisegeek.com/what-is-a-polar-solvent.htm : Last Updated: 14th March 2013.) (See also: http://www.erowid.org/archive/rhodium/pdf/solvent.miscibility.pdf : Last Updated 14th March 2013.) Polar and non polar solvents are related to this experiment because water is a polar solvent and ammonium chloride is a polar solute. This means that the two can mix together. If either one was a non-polar solvent or solute, they wouldnt mix because they dont have a positive or negative pole that binds them together. Endothermic Reactions An endothermic reaction is where a product absorbs energy from its surroundings, causing its surroundings to drop in temperature. In an exothermic chemical reaction the reactants have more energy than the products. However, in an endothermic chemical reaction the products have more energy than the reactants because it absorbs the energy from the reactants and the environment. If ammonium chloride is added in a beaker filled with water and dissolved, the beaker would become cold. This is because it is an endothermic reaction, where the ammonium chloride absorbs the energy from the solvent (water) and its surroundings. This is why we heat ammonium chloride, so that more of it can be dissolved in a solvent (water) and the temperature will not drop rapidly. (See also http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/chemreac/energychangesrev1.shtml : Last Updated 14th March 2013.) What is being investigated? The idea of this investigation is to observe what happens when ammonium chloride is added in a test tube filled with a specific amount of water and heated. The next part of the investigation is to observe what happens when the product is allowed to cool. How is it being investigated? This experiment is being investigated by using a range of equipment. An electronic balance is being used to weigh the ammonium chloride and get an accurate result, and a burette to measure an accurate, 10mL of water which is added into a test tube with the ammonium chloride. An electric hot plate is then used to heat up this mixture, and dissolve it while in the process of heating. Next, a retort stand is used to cool down the mixture, so that you dont have to hold the test tube with your hand since it would be really, really hot! Finally, a digital thermometer is used to get a result of the temperature of when something happens in the test tube, when it is cooling down. These results of the experiment are written down and put into tables and graphs so that others may understand how the results were gathered using these equipment. How will the results be analysed? The results will be analysed by finding trends in the statistics that have been written down. These results will then be put into a table and graph. The table will be analysed to investigate if there are any results that dont fit in and if there is a reason why this result occurred during the experiment. The graph will be analysed by finding if there is a trend between the results on the graph (e.g. a constant) and how they match up. Next, the graph is analysed by checking if there is any inconsistencies or results that seem out of place. Finally, the graph is analysed by testing or checking the results to see if they are correct or incorrect. Materials solid ammonium chloride 2 retort stands 500 ml beaker Hand lens 250 mL distilled water burette burette holder large clean test tube electric hot plate spatula stirring rod digital thermometer 2 retort stand clamps heat mat electronic balance black card safety glasses Method 4gms of solid ammonium chloride was measured and the actual mass was recorded. The solid ammonium chloride was put into the large clean test tube. The burette was filled with distilled water till the level reached 10mL. This 10mL of water was added to the large clean test tube with the solid ammonium chloride. 300mL of hot water was added to the 500mL beaker. The beaker was placed on the electric hot plate. The beaker was heated up to boiling temperature and the large test tube was slowly placed inside with the water level in the beaker 3cm higher than the water level inside the test tube using the retort stand and clamp. The mixture in the test tube was gently stirred using the glass stirring rod until dissolved. The large test tube was removed from the beaker after the solid ammonium chloride dissolved and allowed to cool. The large test tube was stirred and watched using the hand lens and the black card to observe the first crystals form. The digital thermometer was used to measure the temperature of the first crystals forming. The mixture was then heated up again and using steps 7 -11 the process was repeated two more times to get the most accurate results of the crystals forming with 4gms of solid Ammonium Chloride. Steps 1 13 was repeated again using 5g, 6g and 7g of solid ammonium chloride. Discussion Trends The results in Table 1, 2 and Graph 1 all have one trend in common; as the temperature increases, the solubility of ammonium chloride increases. This trend shows that the results are reliable but not valid because graph 2, which is the accepted results, shows that the solubility curve of the two graphs do not match i.e. the values do not match but they follow the same pattern. Another trend in the results is the temperature, which shows that for the solubility of ammonium chloride, each gram that was tested roughly differs by 7 °C. This trend is neither reliable nor valid because they do not match graph 2 and the patterns in the graph are different. Saturated, Unsaturated or Supersaturated These results also indicate that this could be a saturated solution, unsaturated or a supersaturated solution because 4g of ammonium chloride dissolved in water at a temperature of 73.43 °C, though the 7g of ammonium chloride dissolved at a higher temperature of 94.56 °C meaning that it took longer to dissolve 7g than 4g. This, in turn, shows that if more ammonium chloride was added to the 7g of ammonium chloride it would have taken longer to dissolve and once it passed boiling temperature water would have evaporated till there was no solvent left and there would still be ammonium chloride. This would mean that 4, 5, 6 and 7g of ammonium chloride was an unsaturated solution. This is an error because it is completely different when compared to the result of graph 2. This error means that something occurred during the experiment which made the ammonium chloride at a higher temperature or simply a random error where the water was heated before the ammonium chloride was put into the beaker. This error has significantly changed the result as it has increased the temperature of dissolution when it should be a lot lower. Comparison (validity and reliability) Table 1 shows the 4, 5, 6 and 7 grams of ammonium chloride was tested three times to get the most accurate result. These three results were then divided to give an average. The average of the 6 and 7 grams of ammonium chloride in comparison to graph 2 is reliable because the solubility of ammonium chloride increases with the temperature. The average of the 4 and 5 grams of ammonium chloride in comparison to graph 2 could be reliable but the percentage of error is too high for this to be acceptable meaning that there was an error in the consistency of the experiment. Graph 1: Solubility of Ammonium Chloride shows the four averages of each test of ammonium chloride, with a trend-line that predicts the solubility of ammonium chloride between 0 °C and 100 °C. In addition the graph shows that when you keep adding more and more ammonium chloride the temperature for it to dissolve will increase, but only by a few degrees each time. Graph 2: Accepted Values Solubility of Ammonium Chloride are the accepted values of the solubility of ammonium chloride. In comparison to graph 1, both graphs have a curve, though graph 1 has more curve than graph 2, where the curve is very slight. Graph 1 and 2 do not match at all, meaning that there are errors and/or inconsistences in this experiment. Table 1, 2 and Graph Solubility of Ammonium Chloride all fit the theory that ammonium chloride dissolves in water. When we match up all the results in this experiment, they clearly do not match the accepted values. The accepted values are vastly different as graph 1 shows that 39.99 grams of ammonium chloride dissolves at 73.43 °C and graph 2 shows that 39.99 grams of ammonium chloride dissolves at roughly 28.12 °C. The results fit the theory because all four tests of ammonium chloride dissolved in water. The only factors that could have changed this outcome could have been the amount of substance in a solvent which is heated to a specific temperature. In the end graph 1 explains as the temperature increases, so will the amount of ammonium chloride that dissolves. Errors Possible errors that could have occurred during the experiment are: the solid didnt dissolve properly, temperature could have been wrong during the cooling down process, the recrystallization of the ammonium chloride in water was difficult to judge and malfunction of equipment could have caused errors. The reason why the solid might not have dissolved is because the temperature might not have been high enough or I didnt stir it enough. In the case of a random error the solid might not have dissolved but the eye might not have been able to see a very small particle even with a small magnifying glass. The reason the temperature could have been wrong is because when I stirred the mixture, the heat from the bottom of the test tube would have mixed with the cool temperature at the top of the test tube, meaning that when you saw the first crystals appearing the temperature could have still been changing. During the experiment the ammonium chloride solution from the first trials was recycle d to be used for further trials. This could have changed the purity of the ammonium chloride because it looked very different to the normal ammonium chloride. This could mean that while the weight did not present a problem, it may have not been completely dry which could affect the results. The malfunction of equipment could have occurred without my knowledge, such as the balance scale being inaccurate (e.g. the small empty cupcake cups on the scale did not balance at 0). Another malfunction could have occurred with the thermometer not working properly. The loss of ammonium chloride not dissolving could have lowered the solubility of the substance. The likelihood of the scale not working is very low and could be counted as a random error, but if it wasnt working the solubility of the substance would be lower than expected if there was less ammonium chloride and higher if there was more ammonium chloride. The recrystallization could have been the exact same as normal solid ammonium chloride or it could have weighted more or less. This would make the answer higher if the ammonium chloride weighed more than it should. Overall I believe the results and answers I recorded might have been a bit too high or even low, but I definitely know that they arent exact. One way to possibly improve the experiment is to use the exact amount of water and ammonium chloride to get a measurement of solubility (g/100mL). This would prove to be more accurate and would be better suited in a beaker, on top of the electric hot plate as the heat would be dispe rsed around the entire beaker. Further investigations that could be included into this experiment could be finding out the saturated solution of ammonium chloride at a specific temperature. This would be good because it is very likely that every group would get different results and have to explain more in their discussion about errors and if they think that their answer is valid or not. Improvements One way to possibly improve the experiment is to use the exact amount of water to get a measurement of solubility (100mL). This would prove to be more accurate and would be better suited in a beaker placed on an electric hot plate as the heat would be dispersed around the entire beaker. Further investigations that could be included could be finding out the saturated solution of ammonium chloride at a specific temperature. This would be good because it is very likely that every group would get different results and have to explain more in their discussion about errors and if they think that their answer is accurate or not. Conclusion In conclusion I discovered that 4, 5, 6 and 7 grams of solid ammonium chloride was soluble in water at different temperatures. The hypothesis that different amounts of ammonium chloride will dissolve in water at varying temperatures was answered. The results that I recorded werent valid because they did not match the accepted values, though the results were reliable in some cases as they did have a pattern and this pattern matched the accepted values.

Character of Cassio in Shakespeares Othello :: GCSE English Literature Coursework

The Character of Cassio in Othello Cassio is a an expert in strategic procedures and Othello is a Moor general in charge of the Venetian army. Cassio works by Othello's side as the army's lieutenant. Cassio though very useful in the army's duties was a simple-minded man, unconscious of his surroundings and his actions. He told Iago, "I have very poor and unhappy brains for drinking. I could well wish courtesy would invent some other custom of entertainment." Yet, shortly after this statement Cassio finds himself in a state in which he is so drunk he ends up fighting with a Cyprus official. Their naive ways lead them through a storm, it swept away Othello as Iago stood and watched. Othello was an honored and trusted general. His character reflected the honor and respect that was given to him. In scene one Barbantio and Othello confront each other about the couple's love and marriage. Even as her own father's trust grew distant Othello stood faithful as he told Barbantio, "My life upon her faith!" Even though Othello trusted his wife he began to suspect her faithfulness, as Othello's confidant Iago poisoned his mind with thoughts of infidelity. Othello's character reminds me of Edmond Dantes. There seems to be a similarity in the sense that, Edmond's mind was pure and innocent, he didn't even suspect his own companions of betraying him. Edmond's mind continued free of cruel intentions until his mind's capacity began to expand and he soon learned who his real enemies were. Edmond's character changed. His entire life was altered with the help of his mentor. Othello didn't have the assistance of a teacher but he had the assistance of Iago. Trust was the key to their downfalls. Othello trusted without protection. When he trusted someone he depended fully on that individual and committed his life to the faithfulness of that person. He wore no armor against the dishonesty of the cruel and knew how to fight only in the physical realm. "I know Iago thy honesty and love doth mince this matter..."When the revelation came upon Edmond's life he sought out revenge. In the same manner Othello's heart and mind was purely focused on his wi fe, Desdemona. When the poison in his mind began to settle, Othello's trust for Desdemona grew distant and his innocence began to fade. "For I know thou art' full of love and honesty and weigh'st thy words before thou gives't them breath.

Manufacturing System

A&A Toy Manufacturing Company Introduction Observed that the flow of information and logistics management between the client A&A Toy Manufacturing Company and its partners are not yet optimal, it is decided to recommend some information software to the client. As the company still adopting manual accounting system, it caused messy collection of financial and accounting data and human errors. The above problems would be burdens that affect managers’ decision making. In the hope of solving these problems an Accounting Information System (AIS) would be recommend to A&A Toy Manufacturing Company.The client has few employees, so it does not hold a well-structured system to management the employees. The following problems were observed: incomplete labor record, overlapped job duties and difficulties in calculating MPF. To improve human resource management of the client, a Human Resources Management System (HRIS) would be recommended. As the company is not using a well Logistic Infor mation System (LIS), the schedule of importing raw materials is messy; communication with customers is also poor. It is decided to recommend a Logistic Information System to tackle the problems stated above.The lack of Manufacturing Information System (MFIS) created difficulties like volume of inventory has not clearly stated and a scheduled operation is unable to run. A manufacturing information system can hopefully solve the difficulties. It is going to recommend Accounting Information System (AIS), Human Resources Management System (HRIS), Logistic Information System (LIS) and Manufacturing Information System (MFIS) for A&A Toy Manufacturing Company to improve their daily operation. Methods used to tackle the project Firstly, we drafted a project outline by brainstorming.Secondly, we discussed on the type of product that the manufacturing company produced. Thirdly, according to the nature of toy manufacturing company, we picked 4 information systems which benefit for the operatio n of the business. Based on the toy manufacturing company, we have to state what problems that a toy manufacturing company always faced. Lastly, we have to find the information on the selected 4 information systems that helps to tackle the above problems. In the process of doing the project, we faced a lot of difficulties. Then we sought help from our lecturer. So, the project can be finished on time.Our group found a lot of relevant information on the Internet, especially from wiki. Abundant of information are provided to be reference for our project. Logistic Information System (LIS) The logistics Information System is the system managing and controlling information handling processes optimally with respect to flow time and capacity, storage, distribution and presentation in such a way that it contributes to company results in concurrence with the costs of capturing like creation, searching and maintenance. The Logistics Information System is made up of the following information s ystems: * Sales Information System Purchasing Information System * Inventory Controlling * Shop Floor Information System * Plant Maintenance Information System * Quality Management Information System Function of Logistic Information System (LIS) * Correct information product at the accurate point of time * Correct format / quality * Create planning data * Provide an easy-to-use planning functions to support forecasting function * Plan, control, and monitor business events at different stages in the decision-making process * Flexible tools for collecting, aggregating and analyzing data from the operative applications Situation:A&A Toy Manufacturing Company has faced several problems nowadays. It has a poor management in logistic. First, the schedule of importing raw materials is messy. The company does not have a well-organized to manage the inventory stock. It is time-consuming and inefficient for the production line to spend large amount of time in making phone calls to confirm the arriving times of the raw materials. The arriving time is unclear and inaccurate. It is difficult for the company to have an accurate schedule to finish output in production stage under this situation.Secondly, the company does not have well-communicate with customers. They have not set up an accurate date and time to deliver finish goods to customers. It may have to delay or reschedule in the transaction. Therefore, customers always ask about this. It is ineffective and increases the cost to communicate with them. Overall, the logistic management of planning, organization and control of goods and material in A&A Toy Manufacturing Company are chaotic. Logistics information system is needed to solve problem that the company has. Application:Under the situation of the company, Logistics information system is important for achieving the efficiency and effectiveness. First, using information technology in Logistics information systems can well connect with consumers and suppliers. Time cost is decrease by communicate via Email or websites. The date and time for the raw material arrived and deliver product are more accurate than before. It reduces the redundancy of the transaction. Second, it reduces the requirements of inventory and human resources by enabling requirements planning.Logistics Data Warehouse is using for manage the inventory. It is clear and organizes for the company to update and group relevant data. Human resources reduce and bring effective to the company to make the decision. Third, delivery the finish goods to customers are effective by using logistics information system. The transportation of products improves because the company can plan the routes before they send the product to customers. The routes will be simplify and delivery conveniently. The transportation cost decrease.Fourth, it helps to enlarge scales of business through logistics information system. The manufacturing company is clearer idea about storage of raw materials and finis h goods, it is easily to order raw materials from suppliers or deliver finish goods to customers in a right time. They have a good management in inventory. It helps enlarge capacity of receiving order or storage. Software 1.

Firstly, both of the system is using graphical user interface (GUI), employees can easily pick up the new system. In case, encountered any problems both of the systems have supporting team to help the employees. The systems have a fair performance on the user-friendly aspect. Secondly, only Customs Intelligenceâ„ ¢ provided the mobile access function to keep check the inventories location, the predicted time of arriving. LIMS and only perform this function on computers.Thirdly, the RFID tags, only LIMS supported RFID tags to manage the inventory that in the warehouse. With RFID technology it can easily locate the location of the stocks in the warehouse and know the quantity of the stocks. It would be helpful to the business. To conclude, LIMS is cheaper and offered RFID technology, which is a useful tool. Although it does not preform mobile access funct ion, it is not a must to have it. Employees can also know the raw materials location and predicted arrival time from computers. It is enough to fix the messy of making phone calls all the time to know the rrival time. LIMS would be recommended as it can fix the company’s obstacles and have an RFID function which can further help the business to improve. Accounting Information System (FIS) Accounting Information System is a system of collection, storage and processing of financial and accounting data. An accounting Information system is a computer-based method. The resulting financial reports are useful for the internal management and external parties such as investor. It benefits the management to make decision. Functions of Financial Information System (FIS) Collects relevant financial and accounting data * Stores the financial and accounting data * Transfers the financial and accounting data into information, such as financial reports * Provides information to financial exe cutives * Provides timely financial information Situation After working with different functional units of A&A Toy Manufacturing Company for a while, I have observed that the company still adopting manual accounting system. This creates abundant of problems. Firstly, manual accounting system leads to the messy collection of financial and accounting data from different departments.With lots of missing data and the mistakes made by the accountants, it produces incomplete and inaccurate financial reports to the management. Secondly, manual accounting system leads to the wasting time in processing the data into information. After collection of data, the accountants have to record those transactions in to ledger by hand. It is really time consuming. Some of the final financial reports may be out of dated for decision making. Thirdly, the management make decision depends heavily on the financial reports produced by the accountants.As the incomplete and inaccurate provided to management, t he management will make a wrong decision. To conclude, manual accounting system produces incomplete, inaccurate and out of dated financial reports. The process of processing the financial and accounting data into information is messy and time consuming. Application Applying computerize accounting information system can help to improve the financial operation of the company. It brings several advantages to the company. Firstly, computerize accounting information system is automate and streamline reporting. The accountants just have to input the necessary data into the software.It will generate those requested accurate financial reports automatically by the accountants. Secondly, computerize accounting information system can generate financial reports automatically. So it is less time consuming. The accountants no need to record each transaction. The financial reports must be timely as the computerize system can generate reports in fast rate. Thirdly, computerize accounting informatio n system can generate timely, accurate, relevant, integrated financial. It can avoid human mistakes. Therefore, the management can make the correct decision for the business.Fourthly, computerize accounting information system can store the past data and reports. So the data and reports will be more organized and tidy. The probability of losing data will become low. To conclude, computerize accounting information system benefits the operation of business. It is less time consuming in generating timely, accurate, relevant, integrated financial reports in a short period. So, the financial and accounting data can be more organized and tidy. It monitors the cash flow closely in the company. Also, those qualified reports can truly reflect the profitability and liquidity of the company.The management can make the best decision. Software 1. Front Accounting Features: Advanced GST (VAT) handling * several GST (VAT) definitions with GST (VAT) groups * definition of GST (VAT) included * GST (V AT) can be selected on per customer, supplier or item level advanced GST (VAT) inquiry and report showing details and outputs/inputs. Full currency support * historical currency rates * Multi-currency bank accounts, customers and suppliers. 2. Intuit QuickBooks Features: * Allow multiple users to work off the same, up-to-date QuickBooks company file at the same time. Create professional-looking invoices and forms * Customize contact information fields in the Customer, Vendor, Employee Centers * Downloading transactions from financial institution Criteria| FrontAccounting| Intuit QuickBooks| Preference| User-friendly | Fair| Good| Intuit QuickBooks| Mobile Access| No| Online access(extra cost needed)| Intuit QuickBooks| Multiple user | No| Yes| Intuit QuickBooks| Cost| None| USD $199. 96| FrontAccounting| Updating| Yes| Yes| Fair| Support after sales| No| Yes (Extra Charges needed)| Intuit QuickBooks| By comparing the above criteria, Intuit QuickBooks would be recommended.Firstly, as A&A Toy Manufacturing Company is using manual accounting system, a user-friendly system is needed for employees start to pick up. Intuit QuickBooks is more user-friendly than FrontAccounting as it uses graphical user interface (GUI). Employees can get used to the new system soon. Moreover, if the employees encounter any problem, they can seek help from the Intuit hotline. While FrontAccounting just provided some common Q&A sections on the web, it is not specific even cannot help the employee. It would be a waste of human resource.Thirdly, as the managers or the owners may need to preform decision making outside the office, it would be better to have mobile accessing function for their convenience. Intuit QuickBooks provided this function while FrontAccounting does not. Although extra charges are needed for this function, managers could still have the right to consider use it or not. Fourthly, employees may need to access to the same document at one time, Intuit QuickBooks can suppo rt multiple users to work on the same time. It would be more convenient for the employee.Time would be wasted if the employees need to do the job one by one. Fifthly, both of the software have updating to introduce new functions of fix some bugs. They have fair performance on this criterion. Sixthly, FrontAccounting is free of charge, while Intuit QuickBooks cost almost USD$200, it is expensive to the A&A Toy Manufacturing Company. However good AIS could help the company a lot in saving cost and present accurate information for decision making purpose. As, the performance of Intuit QuickBooks is better than FrontAccounting and the cost is for permanent use, thus it is still worthy.To conclude, Intuit QuickBooks would be recommended to A&A Toy Manufacturing Company. Manufacturing Information System (MFIS) Manufacturing Information System is a computer-based system that works in conjunction with other functional information systems to support the firm’s management in solving pr oblems that relate to manufacturing the firm’s products. Manufacturing information provide services to support the manufacturing function, such as the inventory control and order processing for the company. The company may benefit by reducing the manufacturing costs, increasing products quality, and improving inventory decisions.Functions of Manufacturing Information System * Manages manufacturing resources * Enhances the availability of information * Collects and organizes manufacturing quality data in a straight-forward manner * Support inventory decision-making Situation After working with different functional units of A&A Toy Manufacturing Company, our team found that the company was operating with poor information and logistics management. Firstly, without a suitable manufacturing information system, the volume of inventory has not clearly stated during the daily operation.The staffs have to use extra time and manpower to check-up the inventory stock. In case, the staffs of production lines have to check that regularly, this may lower the efficiency since it wasted a lot of company’s resources. Secondly, the company cannot run a scheduled operation since the delivery of raw materials is not on-time. Moreover, the company does not have any concept on managing the manufacturing resources; as a result, the late delivery of raw materials may lead to poor shipment arrangement and customers-relation.Also, the above actions may delay the manufacturing processing, and lower the effectiveness. Application For the suitable manufacturing information system used by the A&A Toy Manufacturing Company, it may turns into conceptual and strategic tool for competitive advantage. Firstly, a manufacturing information system may help in organizing to resources’ data, such as the inventory stock. The system may help the company to keep track on the resources’ states and adjust the internal settings automatically. The usage of the report and control system of manufacturing information system is sophisticated.These kind of high-tech system can reduce the manpower wasted and duplicated use of resources; it may achieves maximum efficiency with minimum error. Secondly, the manufacturing information system includes managing the raw materials needed to be used. A good manufacturing information system can help in arranging the delivery of stocks and the processing tasks. Thus, the system may enhances the effectiveness in terms of ensure to do the processing tasks on-schedule and use the materials with high attainment. Software | Manufacturing Information System (Erp) Software|Company name| Softcore Infotech Private Limited| Features| * Auto Production Planning & Purchase Order prepared based on delivery date while considering available raw & finished stocks. * Production inspection * Final inspection of finished good| As A&A Toy Manufacturing Company doesn’t has a suitable manufacturing information system, the staffs have to us e extra time and manpower to check-up the inventory stock and lower the efficiency because of wasted a lot of company’s resources, we suggest the Manufacturing Information System (Erp) Software.Manufacturing Information System (Erp) Software offers auto Production Planning & Purchase Order prepared based on delivery date while considering available raw and finished stocks, it can help to reduce the manpower to check-up the inventory stocks. Besides, it also can help to enhance their shipment arrangement and customers-relation. Manufacturing Information System (Erp) Software also offers product and final goods inspection, to help A&A to control the quality of the raw and finished stocks. Human Resource Information System (HRIS)Human Resource Information System enables users to perform standard reporting from all Human Resource areas and process personal information, it provided information that helps decision makers define their own report quickly and efficiently. Functions of Human Resource Information System * Manage all employee information * Report and analysis of employee information * Developing online data bases of employee information * Benefits administration (enrollment, status changes, personal information updating) * Developing online searchable data bases of applicant resumes * Training record maintenance SituationA&A Toy Manufacturing Company with the small scale of operation and few of employees, all the information of labor only recorded by the application form individually so there is no complete labor record. This policy caused different management problems of the company: Firstly, without complete labor record, it is difficult for the company to specify labor’s strength and abilities. As a result, the supervisors cannot allocate the most suitable workers to carry out specific job duties. Secondly, as the company didn’t clearly give any instructions to labor that they have to do of their positions. So, their job duties may be overlapped.For instance, both salespersons and customer services need to answer lots of queries from their customers regarding the shipment arrangement, delivery status as well as warranty issues of their finished products. It will lower the efficiency of division of labor. Thirdly, with incomplete labor record, the company cannot recruit qualified candidates to satisfy the need of labor force in different departments. Fourthly, the calculation of Mandatory Provident Fund Schemes (MPF) of labor will be messy, the company cannot certainly calculate accumulate mandatory provident fund of each labor without complete labor record.Application of Human Resource Information System Firstly, Human Resource Information System helps the company to manage and record all employees’ information, Manager can clearly know all the information of labor including their strength, abilities and training record from the Human Resource Information System. Secondly, in order to give instructions to labor, they can have a clearer idea what to do of their positions; manager can offer different jobs according to their strength and abilities. Thus, it can avoid the problem of overlapping job duties. Thirdly, company can develop online database of employees’ information and nline searchable database of applicant resumes, so that the manager can review all the records easily. With online searchable database of applicant resumes, the company can easily search for the qualified candidates from received application form to satisfy the shortage of labor force in different departments. Fourthly, Human Resource Information System can be reconfigured to suit for different kinds of payroll, the system can record their payroll automatically with flexible payroll adjustment, the company can accurately calculate accumulate Mandatory Provident Fund of labor. Software Microsoft Office Access| BambooHR| Cost| * A one-time payment, $139. 99| * Monthly payment * Depends on the number of employees| User-friendly| * Involves graphical user interfaces(GUI)| * Involves tools (e. g. Power Edit)| Update frequency| * Constantly update| * Constantly update| Security| * Fair| * Fair| As a small-sized company, cost is one of the main concerns. To choose the proper system for the human resource information system, we prefer the Microsoft Office Access. Firstly, BambooHR costs monthly and the price is based on the number of labors.As a company with the small scale of operation, although A&A Toy Manufacturing Company only has a few of employees, monthly cost is a liability to them. MS Access only costs $139. 99 and for permanent use, it will reduce the burden of the company on the system. Secondly, MS Access and BambooHR are fair in the user-friendly section, but BambooHR involves some tools for the users to use easily, but they are only helpful in editing and filling the data in it after setting up the database. MS Access involves the graphical user interfaces (GUI), it can he lp the managers to set up the database of the employees easily.Besides, A&A is the company with the small scale of operation and few of employees, it may not have the senior programmers, MS Access offers many features for junior programmers, it is easy to use for A&A. Lastly, BambooHR and MS Access have fair performance on the update frequency and the security, two of these systems constantly update to meet customers’ needs and make the system more efficiency. Because of all the people are concerned about the security of the information systems, include the HRIS, two of these systems have a fair performance in security.For example, they use the firewall to protect the information in the database, and use some software to protect the information when they are in the backup process, such as SSL. To conclude, we suggest A&A Toy Manufacturing Company to use Microsoft Office Access as their human resource information system. Conclusion To conclude, we suggested four types of infor mation system for A&A Toy Manufacturing Company to use and help them to improve their existing state. We recommended Logistic Information System (LIS), Accounting Information System (AIS), Human Resource Information System (HRIS) and Manufacturing Information System(MFIS).Firstly, for Logistic Information System, we recommended A&A to use Logistics Information Management System (LIMS) to help to solve the exist problems such as reduces the requirements of inventory and human resources. LIMS supported RFID tags that can easily locate the location of the stocks in the warehouse and know the quantity of the stocks. Employees can also know the raw materials location and predicted arrival time from computers, it can help to decrease the human resource needed of the inventory management and making calls. Secondly, for Accounting Information System, we suggested Intuit QuickBooks.It uses graphical user interface (GUI) to help the employees to pick up the system easily. Besides, Intuit Quic kBooks can support multiple users to work on the same time, it would be more convenient for the employees to access to the same document at one time. Use computerize accounting information system instead of manual accounting system can reduce the probabilities of error and help the managers to make the best decisions to the company. Thirdly, for Human Resource Information System, we recommended Microsoft Office Access. Access only costs $139. 9 and for permanent use, it will reduce the burden of the company on the system. It also involves the graphical user interfaces (GUI), it can help the managers to set up the database of the employees easily. It can help the manager to manage the data of employees more convenient and efficiency. The managers can clearly know all the strength, abilities and training record of labor from the system and avoid the problem of overlapping job duties. Fourthly, for the manufacturing information system, we recommended Manufacturing Information System (E rp) Software. A&A can use this software to solve their problem.It offers auto Production Planning & Purchase Order prepared, it helps A&A to reduce the manpower to check-up the inventory stocks and enhance their shipment arrangement and enhance customers-relation. In addition, it also provides the product and final goods inspection, it can help the managers to control the quality of the raw and finished stocks. The above information systems with software can help to solve the difficulties. It helps to enhance the management in different departments to be optimal. Our team believes that those software can enhance the profitability in a foreseeable future.

He didn’t have the strength or energy to stay in the cage for long periods of time. So, he sent Sandage to carry out tasks for him. Everyday Sandage would be given coordinates or jobs by Hubble. When Sandage was done recording he data of his work, he would go back to Hubble and give him the results (Overbye 22). This shows how dev oted he was to his research, even if he was unable to handle the job due to old age he compromised. All of Hubble’s work and Sandage work was done on the 100-in telescope, yet Hubble was still able to find the Andromeda Nebulae’s distance for the Milky Way and study red shifts. While the 200-in. telescope was being built, Hubble asked if he could use the telescope for half of its available time. This shows his devotion because he wanted to use the telescope in order to further enhance his research (17). nbsp;nbsp;nbsp;nbsp;nbsp;Edwin Hubble’s curiosity about the universe started at youth and has grown.
