The effects of invasive species on recreational fishing Research Paper

The effects of invasive species on recreational fishing - Research Paper Example First is that the species show very high rate of reproduction. The plant species that are invasive have a much higher rate of reproduction than any other species, which raises the second reason why they are so (Coulatti 138). Second is that the species fall prey to little or no predation at all. This fact gives the species leeway to reproduce and not worry about any form of predation. Thirdly, the invasive species are mostly hardy in nature. Being hardy means that the species can thrive in virtually any kind of environment, including different climates and habitats (Coulatti 140). The impact that invasive species cause on the environment are gross and sometimes irreversible (Verling 272). Destruction of landscape and severe loss of habitats and loss of life by both animals and humans are just but a few of the impacts. The effects the invasive organisms have on the environment include negative impact on bio-diversity, they can cause species extinction, soil erosion and land degradation and change in life cycles of organisms (Verling 273). The weeds found in lakes and rivers, for example the water hyacinth could cause destruction to water bio diversity. First, the weeds in the water destroy all other plant organisms in the water in order to establish their roots some of them even feed on other organisms. This ensures that the weeds remain the apex plant organisms on these water sources thus getting rid of any chance of bio-diversity in the water sources (Callaway 265). Second is the cause of species extinction in water sources (Coullatti 57). In order to fish, it is logical that there be something to catch in the water sources. The invasive species make sure that fishing does not happen. They do this by first, as mentioned above, eating up all the plant life in the water and thus rendering the fish without food. This the main reason for fish extinction. Land and soil

And analysis - Case Study Example Frozen food is also brought in from the kitchen and taken upstairs to the loft where the customers are seated (http://www.rom.on.ca/en/visit-us/shopping-dining/food-studio-caf%C3%A9). On the other hand, c5’s seating arrangement is in a lounge and there are no open spaces to view the kitchen. The lounge is however free from the kitchen noises as it uses a conventional system where the kitchen is far away from the lounge itself. c5 opens from Monday to Sunday between 11am and 3 pm but also has evening services where they have no minimum fee for food and beverages and the charges usually are $1000. According to the Royal Ontario Museum website, both food cafà © and c5 restaurant lounge offer great services including provision of 10% discount to the ROM (Royal Ontario Museum) members (Royal Ontario Museum, n.d., Shopping and Dining). The c5 restaurant lounge website (http://www.c5restaurant.ca/) portrays the restaurant seems as being more elegant and hence will attract highly rated and elegant clients and especially so because of their scenic location (at the pinnacle of the Michael Lee-Chin Crystal with its amazing architecture). It is designed in a lounge manner hence offering privacy, comfort, superb atmosphere most rich and highly classed people normally require and their menu is also on the elegance side (Medicoff, 2007). On the other hand, food cafà © seems to be a food court that is attended by â€Å"the common man† who is mainly in a hurry and does not mind the location, seating arrangement or comfort as long it is convenient enough to grab a quick bite and leave. This is the exact reflection of this cafà © with its open loft space seating around 350 people hence no privacy or comfort, there is noise from the open kitchen and a lot of diners and hence their equipment does not fully serve the pur pose and they may require to expand on their space especially during the peak season where there are many people and less production equipment to serve

Check Your Understanding Essay 2. A principal-agent relationships involves the owners (principals) delegating decision-making authority to managers (agents). A conflict occurs when the agents pursue acceptable levels of shareholder wealth and profit rather than a maximization of profit. They are pursuing their own self-interests. One way that the agents act in their own self-interests would be by focusing on long-term job security. This could cause the agents to limit the amount of risk taken by the firm. The firm may have an opportunity that is considered a riskier venture that could produce high profits if successful. If the venture proves to be unsuccessful, then the agent is at risk of dismissal. Therefore, the agent may avoid taking advantage of that opportunity. This may also impact decisions concerning diversification and the nature of the cash flow. The actions of the agents are impacted by their compensation package, threat of dismissal, and the threat of a takeover by new owners. In order to mitigate agency problems, agents can receive either cash compensation or long-term incentives. The issue with immediate cash compensation is that it can further promote an agent to act in his or her own self-interest. For example, agents may choose a path of diversification that will result in immediate earnings. This could inflate the quarterly earnings that are directly tied to the agents’ executive bonuses that quarter, but hurt the profitability of the company and the value of the stock in the long-run. In addition, the cash compensation could work to take away from resources that could be used in the advancement of other areas of the company in order to promote growth in the company. Long-term incentives would be a better way to reward agents in order to align their interests with the interests of the principals. These incentives include restricted or deferred stock, as well as long-term performance based payments. If an agent owned stock in the company, then maximizing shareholder wealth would be the same as maximizing his own wealth. The agent would want the company to succeed so that he or she could benefit from its success. In addition, long-term performance based rewards could motivate the agent to make decisions that will pay off in the future instead of trying to produce instant results. The decisions made would promote the growth of the company rather than the growth of short-term bonuses (McGuigan, Moyer, Harris, 2011, pp.10-11). 3. Executive bonuses are often directly linked to corporate profitability. If there is a decline in profitability in the overall marketplace, then the performance percentage used to trigger executive bonuses would be affected. Therefore, if corporate profitability declined by 20 percent, then the percentage used to trigger executive bonuses should also decline by 20 percent. However, this may not be the best option if profitability is declining because it would allow the manager a greater ability to receive a bonus even in tough economic times. This could take away from resources that the company needs in order to try to remain profitable or competitive during these times. Therefore, the owners should keep the performance trigger the same or decrease it by half of the percentage that the corporate profitability declined. This may help the managers to try to find inventive ways to still reach that percentage so that they can still receive a bonus. This could be seen as a motivator. On the other hand, this would also mean that that managers’ total performance based compensation could decrease or be eliminated altogether. This could create issues with hiring and retaining the best managers. Many companies attract and retain exceptional executives based on the benefits package that includes bonuses and other perks. A company that is unwilling to adjust the performance trigger associated with executive bonuses may have difficulty attracting managers with the desired qualifications and experience. In addition, the managers hired may choose to only stay long enough to gain work experience and improve their resume before leaving to join a company with a more desirable bonus structure. A company has to find a way to achieve a balance between rewarding managers to the point that it is detrimental to the company and finding a way to maximize the wealth of the shareholders. 6. The goal of shareholder wealth maximization model is to maximize the return to shareholders, and it is measured by the value of the firm’s common stock. It is also concerned with minimizing the risk to the shareholders’ bonuses. The model looks at the present value of all expected future cash flows (McGuigan, Moyer, Harris, 2011, p.8). a) New foreign competitors: This has the potential to decrease the value of the firm and could impact the future cash flows of a company. The introduction of competition in the marketplace can affect the profitability of a company. The level of the decrease in value would depend on the involvement of the firm in global markets and the level of competition. b) Strict pollution control: This has the potential to decrease the value of the firm if the firm cannot adapt to the changes in requirements. If the firm allows the stricter requirements to hamper production, then the value of the firm would decrease. However, if the firm has planned for this threat by having flexibility when making business plans or creating new technology to take advantage of the Go Green movement, then there is an opportunity to increase the value of the firm. c) Unionization: This would decrease the value of the firm. Unionization would create an increase in risk that involves the ability to achieve operational efficiency. There would be a threat of union strikes that could delay or stop the production of products. This would create uncertainty and could affect future cash flows. d) Increase in inflation rate: In the shareholder wealth maximization model, an increase in inflation rates would be a factor that is out of the manager’s control and influences the price of a stock. Inflation would increase the cost of goods and services, while decreasing the purchasing power of money. An increase in inflation would decrease the value of a firm. If a company has the inability to purchase the same amount of goods with its money, then there is an increase in money spent in order to get the same amount of goods. Increased spending affects cash flows and would decrease the value of the firm. e) Reduced production costs through technology: This would increase the value of the firm. The reduction in the production costs would increase the overall profit. In addition, it has the potential to create more resources within the firm. The extra money from reduced costs could be used to improve other areas of the business in order to grow the business. This has the potential to increase future cash flows, which adds value to the company.

Automation of Plastic Grinding Plant using HMI and PLC

Automation of Plastic Grinding Plant using HMI and PLC CAREER EPISODE: 03 INTRODUCTION: 3.1) The career episode three presents an extensive description of the project Automation of plastic grinding plant using HMI and PLC. This project was part of my industry internship Project 2 in the final semester, as well as a requirement to complete my degree, Bachelor of Engineering (Electronics and Communication)from Gujarat Technological University, India. I started this project with a team of three engineers including myself and a project trainer. The project duration was five months which included project training, implementation and testing. We worked as Electronic engineer interns in Mega Switchgears, India for this project. BACKGROUND: 3.2) In most of the small-scale industries the fault detection is done through manual means i.e. a lot of time is spent in identifying the exact point of error/failure in a particular system. It is a very exhausting task for the operator to check each and every machine in order to locate the error. To make work easier for the workers, we made an arrangement that displays a message on the HMI (Human Machine Interface) display which indicates the location of the error. 3.3) In this project, our main objective was to develop an automation system for a plastic grinding plant using HMI and PLC (Programmable Logic Controller). With the help of this automation system, we were able to monitor and control the plant from a remote location. In other words, status of each module could be monitored without going to the location of the plant and also it sends a message or alert with the location of the error whenever there is a problem or failure in the plant. 3.4) My roles and responsibilities included: Programming of PLC using WPL software Simulation of Plastic Grinding plant on HMI using Screen Editor software Assisting in designing the hardware prototype of plastic grinding plant Maintaining neat and organized electrical connection between different components Discuss future tasks and assess every team members work in weekly meetings. Maintain technical documentation. 3.5) Project mechanism PERSONAL ENGINEERING ACTIVITY 3.6) For this project, we went through an extensive training program for five months and simultaneously we completed our project implementation as well as the testing. We were working as interns in the organization. This training gave us an insight to the technical culture of an electronic industry. During this internship, we came across many new electric components such as PLC and HMI and learnt new approaches to design an electronic circuit in an organized manner as per IEEE design standards. I was trained by the project trainer in programming the PLC and HMI using different softwares. As a team, we were trained in designing and implementing the prototype of an automated plastic grinding system. During our training, we were also given lessons on safety measures to avoid hazardous situations. For a safety environment, we were provided gloves, clothes and glasses to design electronic circuit and mechanical hand. 3.7) Hardware Implementation We started with the designing of the prototype, discussed regarding the work process of the system and selection of components. In this project, we used DVP12SA PLC which was selected under the guidance of our project trainer and depending upon the application of the project. It consists of 8 input ports and 4 output ports. PLC is programmable controller which comprises of a microprocessor, input and output module, memory and power supply. It behaves according to the status of the input and output ports which depends upon the stored program in the memory of the PLC. Therefore, we decided to use PLC for our project. For the controlling and status condition of each module of the plant, I have used 8 channel and 4 channel relay cards, toggle switches and indicator lamps. Relay card is a device on which relay is mounted and can be used for controlling purpose, toggle switches for controlling certain aspects of the machines and indicator lamps are used for indication purpose of plant cond ition. These lamps have very good visibility.RS232 cable is used as a programming cable and RS485 is used to interconnect the PLC and HMI. To provide efficient power, in this project we have incorporated SMPS (Switched Mode Power Supply) Hardware Implementation with the mimic of the plant 3.8) Furthermore to automate the plastic grinding plant, we have also used Delta (DOPB07S211) HMI. I decided to use HMI in our project because it allows you to design the perfect plant diagram using a software and shows on the display screen. This made it really easy for me for the simulation process as well as monitoring the point plant from a remote location. The key feature of HDMI is to detect the exact location of the fault in the plant whenever any abnormal condition occurs such as If any motor will trip due to any abnormal condition then motor and related device process will stop and hooter gets ON, that gives a warning to the operator with audible sound. Operator can also verify which motor is tripped by visual indication on mimic by indicator lamps. 3.9) Software Implementation For software implementation, I was trained by our project trainer for two months. I used WPL Editor for PLC programming. This software is capable of providing 3 languages i.e. Ladder (LAD), Instruction (IL) and Sequential Function Chart (SFC).ÂÂ   It was easy to use the software but it was as difficult to program the PLC because the programming was implemented depending upon the various conditions of the plant and in those situations what action should be taken. After every minor implementation, I used to verify the action of the PLC in order to complete the programming successfully. For this project, I used Ladder language to program the PLC. 3.10) The second software which I was trained for was Screen Editor. I used screen editor to design the mimic diagram of plastic grinding plant with touch buttons that were used to control each module of the plant. This software is comparatively much lucid than WPL Editor software. I also incorporated colour code system for various fault condition such as follows: REDFeedback/Input is not given in system GreenSystem is running smoothly with no fault conditions YellowInterlocking the problem in the system Screen EditorHMI Display SUMMARY: 3.11) In the end after the implementation and documentation, we presented our project with the automated prototype of plastic grinding plant and gave a presentation in front of our faculty. The overall journey of this project was very productive in terms of learning, acquiring knowledge and enhancing technical skills. I faced many tough situations while pursuing this project such as programming the PLC and constructing the prototype but working under the guidance of our project trainer and as a team, made the project look easily achievable. For future prospective, system can be controlled using a computer at remote location by connecting HMI with an ethernet cable, record of faults occurring in the system can be recorded in the excel sheet and the system can be also password protected.

Technology and Art :: essays research papers

Does size matter? In the world of technology, it all depends on the consumer. The first generations of televisions were designed in a very simple form. Most were square, made of wood, and had a round dial to change channels. Nowadays, we have many different shapes and functions for televisions. Culture and technology have had a large impact on the development of the design and features of the modern television. The design of the television has drastically changed over time. For example, the 1948 Fada model was large in volume and it had a convex and oval shaped screen. It had four knobs used to tune and change channels. The structure was made of wood and it included a fairly large speaker underneath the twelve inch screen. The television only had access to thirteen channels. The dial simply shows that the culture did not have access to many channels. Past televisions were simple because the lifestyle was simple. People did not need hundreds of channels and massive screens to be satisfied. Modern televisions now come in various sizes and have features to accommodate the consumers. For example, the Philips-Magnavox 50FD9955 is thin and has a fifty inch (diagonal) rectangular flat screen. This television can be placed almost anywhere imaginable. It can be hung on a wall or even on the ceiling. The large size of this television represents modern society’s need for bigger and better things. It has an on/off button, two channel buttons, two volume buttons, and other various buttons for adjusting the color. The channel buttons on the modern television represent the unlimited number of channels. The structure is made of metal and plastic and it includes a speaker on each side. The plastic body is easier to mold, cheaper to produce, and easier customize the color. The television comes with standard audio/video jacks, cable jacks, and an S-Video jack to accommodate VCRs, DVD players, camcorders, and other accessories. These additional features did not just appear overnig ht, they developed with society to satisfy their needs. Television is designed around its culture. In the past, watching television was a way for families to be together. Everyone gathered around the television and watched the same show. Families did not have the luxuries of owning more than one television and having hundreds of channels. Today, almost every room in the house has a television. People in different rooms are now able to watch their own shows.

Francis Parkman :: essays research papers fc

Many people regarded nature and the world with their eyes only. However, some perceived the world through all their senses. They stopped and listened to what appeared before them, and then they experienced their surroundings. One person who looked beyond his first impression was Francis Parkman. Parkman’s love for history and nature drove him to overcome his physical weaknesses. He pursued his passion with the diligence of a soldier and brought a different perspective to nineteenth century history. Francis Parkman traveled across North America and obtained firsthand experiences about nature, hardships, and the unknown. He developed his quest for knowledge as a child on the Hall Farm in Quincy, Massachusetts. Parkman battled the degenerating loss of his health, the loss of only son, and the loss of his wife. He compiled his wisdom in letters, journals, articles, and books; and Parkman left a legacy unmatched by historians of his time. On September 16, 1823, the union of Reverend Francis Parkman and Caroline Hall Parkman produced a son, Francis Parkman, Jr. The Reverend and Mrs. Parkman, his second wife, resided in Somerset Place, Boston, and the family tree consisted of ministers, merchants, philanthropists, and brave Indian fighters. The Parkman family spent winters in Boston and summers at the Hall farm in Quincy, Massachusetts. The farm in Quincy provided Parkman with a vast area of rocks and forestry to explore, since it happened to be located adjacent to the Five Mile Woods, later renamed the Middlesex Fells. He encountered many illnesses in Boston, and his parents decided to leave him in his grandparents’ care on the farm. On the farm he collected rocks, trapped animals, shot arrows at birds, and conducted experiments. He wrote about himself and his experiments in the third person just as his peer, Henry Adams, regularly did. Parkman returned home to his parents at age thirteen to begin private school ing. Parkman attended Gideon Thayer’s famous private school, Chauncey Hall, in order to prepare for college at Harvard. He entered Harvard in August 1940, and he excelled academically, physically, and socially. In addition to his regular studies, Parkman joined several school clubs and helped found another one. In July 19, 1841, during summer break from Harvard, he and Daniel Denison Slade took a trip to explore the White Mountains located in New Hampshire and Maine. Parkman, aware of an avalanche that killed nine in 1826, eagerly climbed the unstable flume close to Notch House.
