Pulse Width Modulation Final Year Project Essays Pulse Width Modulation Final Year Project Paper Pulse Width Modulation Final Year Project Paper Chapter 1 Introduction 1. 0 Background Pulse Width Modulation (PWM) is a type of devices that can be used as a DC motor speed controller or light dimmer. PWM is used extensively for speed controller where power-saving application is needed. This device has been used as a motor speed control for small DC fans, for example in computer power supplies. A PWM circuits works by creating a square wave with a variable on-to-off ratio, the average on time may be varied from 0 to 100 duty cycle. The term duty cycle describes the proportion of on time to the regular interval or period of time; a low duty cycle corresponds to low power, because the power is off for most of the time. Duty cycle is expressed in percent, 100% being fully on. From this, a variable amount of power is transferred to the load. The main advantage of PWM is that power loss in the switching devices is very low. When the switch is off there is practically no current, and when it is on, there is almost no voltage drop across the switch. Power loss, being the product of voltage and current, is thus in both cases close to zero. PWM also works well with digital controls, which, because of their on/off nature, can easily set the needed duty cycle. Additional advantage of PWM is that the pulses reach the full supply voltage and will produce more torque in a motor by being able to overcome the internal motor resistance easily. 1. 1 Objectives The objectives of this project are: 1. To develop the actual circuit of the PWM. 2. To simulate the PWM circuit in simulation software. 3. To use the PWM in order to control the speed of the DC motor. 1. 2 Methodology Start Title consideration, ideas Supervisor approval Components specifications and data sheets Proposal Drafting Proposal Evaluation Project Simulation Project Presentation Progress Report Submission END Figure 1. 2. 1 Flowchart of Methodology 1. 3 Gantt Chart 1. 3. 1 Final Year Project 1 | WEEKS| ACTIVITY| 1| 2| 3| 4| 5| 6| 7| 8| 9| 10| 11| 12| 13| 14| 1| Student-supervisor-panel allocation, briefing about FYP, introductions| Â  | Â  | | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 2| Student-supervisor meeting arrange time, finding ideas discuss ideas, project titles| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 3| Student-supervisor regular meeting| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 4| Proposal preparation| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 5| Proposal evaluation, meet supervisor for evaluation, things to be improved| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 6| Proposal correction correct any mistakes| Â  | Â  | | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 7| Project Development choose circuit, check availability simulation| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 8| Proposal and progress presentation| Â  | Â  | | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 9| Progress report writing is based on progress| Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 10| Progress report submission submit report| Â  | Â  | | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | 1. 3. 2 Final Year Project 2 Week| 1| 2| 3| 4| 5| 6| 7| 8| 9| 10| 11| 12| 13| 14| Tasks| | | | | | | | | | | | | | | Buy Components | Â  | Â  | Â  | Â  | | | | | | | | | | | Construct circuiton breadboard | | | Â  | Â  | Â  | | | | | | | | | | Troubleshoot| | | Â  | Â  | Â  | | Â  | Â  | | | | | | | PCB Layout Design| | | | | | Â  | | | Â  | | | | | | PCB Layout Print| | | | | | | | | | Â  | Â  | | | | Soldering| | | | | | Â  | Â  | Â  | | | | | | | Final Report| | | | | | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Â  | Final Presentation| | | | | | | | | | | | | | | 1. 3. 2. 1 Aims for Final Year Project 2 1.

Troubleshoot 1. 3. 2. 2 Project planning for Final Year Project 2 For the final year project 2, we have to prepare the actual circuit based on our simulation result. We will create the PCB artwork with PCB programming such as ExpressPCB, which is available for free and is surprisingly functional. Next, we have to print out the PCB artwork on a transparency. Then we cut out the printed portion of the artwork. This will define the size and shape of the PCB. To make PCBs, we can use the UV exposure method, which is only slightly more difficult than and significantly more precise than the toner transfer method. To start out, we must cut the PCB to be the same size as the outline of the PCB positive. First, we drew a rectangle the same dimensions of the PCB on the protective layer of UV Reactive copper covered ibreglass board, and then cut it out using a Dremel tool equipped with a diamond wheel. We have to make sure that once we have removed the board from its protective package it will not be exposed to any UV. Fluorescent and halogen lights both output enough UV light that they will expose the board through the protective layer of plastic. Next, after we cut the UV sensitive PCB to size, we are ready to expose the board. Then we remove the protective layer to size, from the PCB right before we place the positive on it, or else dust particles will attach to the board, which will mark the final PCB. To expose the PCB, first remove the protective layer, place the positive transparency on top of the board, and place it in the UV exposure box. An exposure time of 10-11 minutes is recommended. Now we need to drill holes in the PCB for the through-hole components. Finally, we have to solder all the components through-hole components. If the final result is not achieved when testing the final circuit, we have to run troubleshooting and find out the problem. Then, we solved the problem based on the troubleshooting after we identify the real problem.

The IC NE556 will generate square wave. The wave will then go to the second half of IC NE556 and been modulated. Potentiometer will control the second half IC to produce the desired output. A modulated square will be generated from the second IC. This wave of current will be amplified by IRF521 and then went to the motor and spin it. The DC motor speed will depends on the magnitude of the current. Chapter 3 Project Progress 3. 0 The Project Progress and the Project Outcomes The first stage of the progress is building the circuit for the Pulse Width Modulation (PWM) circuit. Then, the best circuit diagram is chosen for our project. A preliminary literature review about our circuit had also been done. In this project, two of the LM556, Dual 556 Timer TTL IC were used to simulate the PWM circuit. The first IC allowed the possibility to generate square wave while the second IC allow modulation variation. Other than that, several problems were encountered when simulating some part of the circuit. This is due to incomplete library component of the simulation software such as the lack of LM556 IC in the first place. This was because the wrong type of licence of the software was selected. After a few trials and some changes of the circuit diagram for simulation, and with the right licence for the software, the PWM circuit was successfully simulated. Figure 1. 1 Expected DC square wave (output) Results Input Signal of 1st half of IC NE556 Output Signal of 2nd half of IC NE556 Calculation from theory: Thigh= 0. 7(RA+RC)C Thigh= 0. 7(1M+1K) (0. 05Â µ) = 0. 035s/35ms Tlow= 0. 7 RB C Tlow= 0. 7 (1K) (0. 05Â µ) = 3. 510-5s/ 0. 035 ms Values from simulation: Thigh= 38ms Tlow= 42 Â µs/ 0. 042 m Input Signal of 2nd half of IC NE556 Output Signal of 2nd half IC NE556 (A=0%, B=0%) (A=0%, B=10%) (A=0%, B=50%) (A=0% B=100%) Calculation from theory: Thigh= 1. 1 RA C Rated Current From Simulation (A=0%, B=0%)I=45. 842mA(A=0%, B=10%)I=132. 953mA (A=0%, B=50%)I=406. 541mA(A=0% B=100%)I=4. 121A Table of Motor Speed Slow| Speed| Fast| 0%| Value of Potentiometer B| 100%| 0. 2077ms| T high (ON time)| 7. l79ms| 132. 95mA| Rated Current| 4. 121A| 12V| Rated Voltage (Constant)| 12V| Since voltage is constant, the higher the current supplied, the faster the motor would spin. Chapter 4 4. 0 The Problems Encountered CASE 1 – FINDING SUITABLE SIMULATION SOFTWARE The PWM circuit uses two of LM556 IC. The first LM556 will convert DC input signal into square wave. Before doi ng the hardware of the project, the software need to be simulated first to check whether the circuit diagram is correct or need some adjustment. Because of this, finding the suitable simulation software had become a problem encounter to finish the project. List below show example name of other simulation software that can be used to run any the software simulation for the project; 1. TINA 2. OrCAD Capture 3. PROTEUS All of the other simulation software above can be use to run the simulation for this project but some of them were not suitable. As an example the TINA software were not used because of the unfamiliarity and the complexity of the software. The project also cannot be simulated using the OrCAD Capture since there were a large number of library which does not have simulation installed. This make it unsuitable since this project required to be simulated. Meanwhile PROTEUS software was not used because of the difficult interface that complicate the user or in other words not user-friendly. CASE 2 – WRONG LICENCE OF SIMULATION SOFTWARE After MULTISIM had been installed, a situation was encountered where the library components are not complete or some of the components are not available. If this problem prolonged, the circuit cannot be designed in the software. Some measures had been taken to find the solution but the problems still persist. There are some types of licence that accompanied for MULTISIM, which are: 1Power PRO Edition 2Full Edition 3Student Edition 4Education PKG Edition 5Base Edition At first, the Full Edition licence was installed. When the circuit was being designed, a lot of components were unavailable. Every aspect of the software was checked, but no problem related to the software was detected. The MULTISIM software was cleanly installed in the computer. . 1 Solutions for Every Problem CASE 1 SOLUTION – USE MULTISIM SOFTWARE The simulation can be done by using simulation programmed like TINA, Proteus, or OrCAD Capture. Unfortunately, all of these simulation programmed mentioned above have problems as explained before. Without a proper simulation, it is hard to detect any problems that exist in the design of the circuit. Finally, MULTISIM i s chosen as the simulation program. MULTISIM was suitable for simulation of the Pulse Width Modulation circuit. MULTISIM has all the required components in its component library. Hence, all the components can be place in the circuit to complete it. Simulation can be done easily by using MULTISIM. All the results being cleared by using this programmed. Expected results are the PWM wave which will control the motor. CASE 2 SOLUTION – WRONG LICENCE OF SIMULATION SOFTWARE This problem was easily encountered by reinstalling licence of the right type. In this case, PowerPro Edition licence type was required. After it has been reinstalled, all the components are unlocked. Hence, the process of designing the circuit in the simulation software continued, and simulation process succeed. Chapter 5 Conclusion For this semester, the project progress was successful until the simulation. Hence, the simulation needs to be done correctly according to the circuit so that expected result can be obtained. The circuit diagram for PWM to Control DC Motor Speed has been successfully designed. Thus, the first objective has been achieved. The progress of the project works efficiently if the project followed accordingly to the Gantt chart made at the beginning of the project. The Gantt chart contains all the important steps that need to be followed in rder to finish the project successfully. All the steps in the Gantt chart been mentioned with respective date. Hence, there should be no problem during Final Year Project 1 when all works were being done according directly to the Gantt chart. The simulation for PWM to Control DC Motor Speed had been done by using simulation program, MULTISIM. MULTISIM provides all the necessary components to complete the simulation for the PWM circuit . Since the output should be a DC motor or a DC fan, it was replaced with Oscilloscope or Multimeter to observe the changes that occur in the simulation. This shows that choosing MULTISIM is the smart choice to run the simulation because of the advantages and the ease of use that this simulation program has. REFERENCES 1.

JFK assassination Essay Example | Topics and Well Written Essays - 1250 words

JFK assassination - Essay Example Kennedy was a charismatic leader whose assassinationhas remained a debatable issue several decades after his death. Many years after his death, it has not been possible for the world to know who gave the official orders to kill him and what their motives were. Those who witnessed the shooting of Kennedy have never come to an agreement on where the shots were from, therefore making the issue more controversial. There have been further disagreements with some people arguing that there was more than one gunman involved in the shooting, while others conclude that it is impossible to know the exact location of the shooters and the number of shots fired. In the theories raised about the murder of Kennedy, arguments revolve around the role Oswald had to play in the killing. Theorists believe that he was not solely responsible for the murder on grounds that he did it on behalf of someone else. Oswald was framed by those who responsible for the murder so that they could cover up their involve ment. Those alleged to have participated in the assassination include the CIA and the American Mafia (Plouty et al, 2011 p 233). A number of circumstances are believed to have caused the assassination of Kennedy. ... This led to a lot of criticism fromthe Mafia, and it was the probable reason as to why they planned to assassinate him (West and Vernon, 2011). Another controversial issue leading to the assassination of Kennedy was the Bay of Pigs invasion in1961. The attempt by the Cuban exiles to overthrow the government of Fidel Castro was not successful. This was because President Kennedy declined to permit American troops and the CIA to attack Cuba. After the failure of the attack, the deputy director of CIA Charles accused Kennedy of being a traitor. As a result, the CIA was unhappy with Kennedy and they had to look for alternatives; they therefore sought the services of the Mafia to kill Castro (Plouty et al, 2011 p 234). After two years of his tenure as the president of the United States, Kennedy faced great opposition from both the democrats and the republicans in the congress. Most of the legislations that he proposed were rejected, and this meant that he had less support in the congress i n his position as the president. More so, his involvement in the affairs of Cuba was threatening his future in the American politics. The Republicans used the Cuban issue to object to the president and planned to assassinate him (Gibson, 2000 p 8). The Vietnam War had a part to play in the assassination of President Kennedy. Kennedy approved the National security memorandum, which declared America’s intention to pull out of the war by withdrawing their troops. Kennedy’s decision to withdraw from Vietnam was objected as it signified that America would cease to support its allies in the Vietnamese war. Kennedy stood as a threat and consequently there was a plot to assassinate him and end his rule so that America would continue taking part in the Vietnam War. The

Political Correctness Assignment Example | Topics and Well Written Essays - 250 words

Political Correctness - Assignment Example Protecting the rights of minorities is important due to external factors such as gender and race in relation to the use of offensive words. Moreover, not everyone reacts to situations, in the same way. Some people are more irritable than others (Uelmen 1). Sometimes, things get out of hand leading to dangerous fights or bitterness that leads to revenge. Choice of words should be based on the relationship between individuals and the situation at hand. While some people might entertain jokes, some may interpret them as being offensive. The dynamics of choosing words vary depending on the situation. It is better to avoid offensive words because the mood in which people might be in is sometimes unpredictable. On the other hand, maintaining a stand in terms of being able to say yes or no is usually the right thing to do. Saying no can and should be accompanied by the right choice of words. Disagreeing with something does not imply that people should offend others. Being fearful on the choice of words is not a sign of weakness as some may interpret. It is an implication that besides being mindful and respectful, people regard others with high

Effect of Candle Color in Burn Time

Effect of Candle Color in Burn Time Problem Statement What is the process of a candle burning? Does adding dye affect a candles burning rate Do colored candles burn quicker because the added dyes? Colored candles are popular in homes, their pleasant scents, relaxing traits and decorative qualities are only a few reasons why people love them. I myself a candle lover have noticed that different candles burn at different speeds. Which lead me to question, if the dyes used to color the candles affects its burning speed? Specific Question: Does adding dye to color a candle affect its burning rate? Background Research: To fully comprehend if using dye to color a candle affects its burning rate, it is essential to examine and comprehend the candle itself along with its burning process. A candle is a piece of tallow or wax with an embedded wick. A candle is made by paraffin wax which comes from crude oil. When exposed to a temperature of 380 degrees or higher paraffin automatically combusts. The wick is composed of porous coil. The candle burning process The melting process of a candle is simple; first the wick is lit, which starts the flames journey down the wick were will ultimately reach the wax. Consequently, the warmth of the heat melts the molded wax into a liquid. Subsequently the wick absorbs the newly melted liquid and uses it to fuel the flame. Therefore it is the liquid wax of the candle that fuels the flame, allowing it to continue burning. Experimental design The experiment will consist of burning a variety of five colored birthday candles and recording the speed at which each candle burns. Plan: The experimental will be performed on my dining room table. Each candle will be individually placed in a candle holder, next both the candle and the candle holder will be placed in a tea cup, and then the candle will be lit and timed. 1) First, gather all the needed supplies, A variety of five colored birthday candles Candle lighter Stop watch Candle holder Tea cup Scissors Marker Metric Ruler Data sheet 2. Each candle will be measured and marked one inch from its bottom. 3. The white candle will be lit and timed first. 4. The white candles burning time will then be recorded. 5. The prior steps will be repeated for each of the remaining candles individually. 6. Following the completion of the candle burning process, the recorded results will be compared and a graph representing the results will be created Variables: Independent The color of the candle will represent the experiments independent variable. Dependent The rate at which each candle burns will be the experiments dependent variable. Controls The following will be the controlled variables of the experiment. The measured distance of the mark in the candles. The brand of the candles will be the same. The burning of the candles will be performed in the same time and place. The temperature of the room will remain the same while each candle burns. Threat reduction to internal validity The following steps were taken in order To minimize error during the experiment, the candles will all be the same brand the candles will be measured and marked to ensure all candles are the same size Each candle will be placed in a candle holder and then in a tea cup in order to eliminate unexpected elements Hypothesis The speed at which a candle burns is not affected by the dyes used to give the candle its color. To develop this hypothesis, the research was carefully considered, The National Candle Association explains that dyes used in candle coloring are dissolved and mixed with the waxs oil. Since the added dyes do not clog the fibers of the wick, the candles burning ability is minimally affected. As a result candles colored with dye should burn at the same rate. These researched facts lead to the conclusion that added dyes do not affect a candles burning rate. Explain the process of data collection The candle burning process research was collected through Measurements Time will be calculated with a timer Candles will be measured with a metric ruler. Pre experiment predictions Experiment Results Yellow Candle: 8 minutes 24 seconds Blue Candle: 8 minutes 54 seconds White Candle: 9 minutes 4 seconds Pink Candle: 9 minutes 20 seconds Green Candle: 9 minutes 22 seconds Written Results The results of the experiment resulted in the yellow candle reached its mark the fastest, and the green candle was the slowest burning candle. The candles burned in the following order beginning with the fastest: yellow, blue, white, pink and last green. The graph shows the rate of the candles burning with 8 minutes being the fast and 9 minutes being the slowest. The graph also indicates that the dye doesnt affect the speed at which a candle burns. The white which is the lightest color was the third fastest candle to reach the mark, not the first as previously stated. Blue the darkest candle finished second fastest. Conclusion The hypothesis stated The speed at which a candle burns is not affected by the dyes used to give the candle its color. The results of the experiment supported the hypothesis and proved that the dyes used to color candles have little or no affect on the candle burning rate. Discussion The results of the experiment conclude that candles do not burn at the same rate also they do not burn according to the lightest to darkest colored. The results of the experiment confirm that the dependent and independent variables have no relationship. The data from the experiment answered the research question: Does the added color in a candle affect the candles burning rate? The experiment concluded that adding color to a candle does not affect its burning rate. Abstract: Summary of the experiment The stated problem: Does adding color to a candle affect its burning rate? A variety of five colored candles, all of the candles were the same size, brand and tested under the same conditions. The colored candles used to conduct the experiment were yellow, blue, pink, white and green. The candles were all measured one inch from the bottom to ensure the burning time be identical. Next the candles were lit and the timer was started. The times were then recorded. Following the experiment the data was then compare and the results confirmed that the added dyes in candles do not affect its burning time. http://www.blurtit.com/q465603.html http://www.candles.org/elements_wax.html

Design Elements in Fashion

Club's new album Champ is pretty damn adorable. I put it on in the car during a rare burst of winter sunlight a few weeks ago and for a few seconds I actually believed it was summer. This is the Ontario band's second full length album, following Elephant Shell in 2008. Lead singer David Monks is only 23 but has produced an incredibly nostalgic album where he describes moments as if they were a lifetime ago, not a few years.For anyone who hasn't heard much of this four-piece Canadian band I would highly recommend them. The song ‘Tessellate' from their first album is one of the loveliest songs I have ever heard, with a youthful outlook on the world and lyrics far beyond their age. David Monks' voice never fails to make me a bit weak at the knees. As well as this they are highly capable of producing catchy, dance around like a frenzied monkey, tracks. The new album is about secrets, growing up, growing apart, double knots, Christmas Cards, favorite foods, favorite colors and endin g your way.The only criticism I can give is that sometimes the lyrics seem too â€Å"teenager†, especially for your Monish educated ears. However sometimes it's nice to reminisce on those moments before everyone cut loose on Schooling. I think Champ will cement their place as one of the most interesting bands to watch at the moment. The album is out September for Australia, and in the words of one highly astute Youth user, â€Å"the man has a voice tuned for a women's vagina†. Amen.

Diet Analysis Paper

The three-day diet analysis was interesting. There were many positive attributes to it and definitely negative ones. Over the course of the three days, which were Friday, Saturday and Sunday: and figured this would give a good depiction of what I was consuming on a regular basis. In some places I was consuming more than I should be and in some I was consuming less than I should be. There were also those places were I was getting just the right amount. It is so interesting to me to be able to find out what I am consuming and how I am consuming it. Being an active male, it was most interesting of what I ate, what my average of the three days were, and the plan on how I would correct the way I eat to make it a more healthier lifestyle. My Pyramid was not that shocking, when I saw Grains, fruits, vegetables, milk, meat, and bean intake compared to the recommendation. Personally, it made sense of what I was meeting and what I was missing, yet, have done nothing about it. I love my grains, even though I am a celiac. I do not really follow the guidelines and still chose to eat a lot of grains. This was at 10. Oz and I met the required intake for grains. The vegetables I tend to eat are broccoli, carrots, and from time to time I eat cauliflower. So, I was at 1. 2 cups of vegetables compared to the recommended intake of 4. 0 cups. I already knew I hardly reach the fruit intake that happened to be zero percent. I have never been a big fruit person, besides eating apples to keep the doctors away. Got milk? Of course, I always drink my milk when I eat all the grains out of the cereal bowl. Thus, I was at 1. 5 cups compared to 3. 0 cups of the recommended intake. Lastly, meat and beans I was at 5. 5 oz and cheated, because I ate at taco bell! Overall, the above groups did not surprise me and did show me how far I still was to reaching the food-list compared to the latest USDA Dietary guidelines. My actual intake for Protein was at 83. 30 grams and exceeded the recommended by 8. 91 grams. When looking at the meal assessment, lunch was when I received the most protein during my three-day analysis. I normally eat out during lunch, because I am either at school or work and it is convenient. I usually do not think of whether or not I am cooking the right foods that have a good amount of protein at dinnertime, and rely on fast-food chains. Since, I am over on my protein intake I am not worried about having to rely on fast-food to get the appropriate amount my body needs. Carbohydrates (carb) for me were at 206. 36 grams when it should be at 554. 37 grams, so not exactly where I need to be. Again, my carb intake was the highest during lunchtime. The foods highest in carbs high in starch or sugar would be found in the grains (Cinnamon Toast Crunch), starchy potatoes (French fries), and any foods with added sugar. Low carb foods I consumed were the meat (lunch and dinner), eggs (breakfast), and the small portion of vegetables (broccoli and carrots). Total fat was 63. 9 grams compared the 125. 43 grams of total fat recommended. Also, my saturated fat was 18. 16 grams when listed at 40. 32 grams of recommended intake. Not too sure on fats, except from the fact that the key is to replace bad fats (saturated and trans) with good fats (poly and monouns) in our diet. Knowing which fats will raise my LDL cholesterol and which ones will not is the first step to lowering my family’s history of heart disease. Cholesterol was 254. 51 mg, which was very close to my recommended intake. If there is one thing I learned so far this semester, it is to eat foods that are low in cholesterol, saturated fat, and free of trans fat. I have never had a screening done before, yet, seeing that my Cholesterol was fairly high, I might reconsider. Being an athlete I know I can use all the fiber I can get to keep my digestive system clean. During the three-days, I only took in 17. 20 grams and I should be consuming at least 56. 44 grams. Fiber can be found in fruit (I did not eat during the trial), vegetables (I ate very little), and wheat foods that were most likely the main source I got the fiber from. On an infomercial with Montel was selling his new â€Å"Health Master† blending machine. During his spiel, he started talking about how the majority of us add salt to foods that already have a good source of salt. I found it interesting, because I know I do this when I get chips or chili. From what I got, the key to healthy eating is choosing foods lower in salt, sodium, and try to not add extra salt to foods (unless your mother’s cooking is bland). Well, I had a very high intake of sodium of 2,730. 78 mg when it should have been at 2,300 mg. I usually stop by the blood pressure machine when at the grocery store and it tends to be good. So, I am not too worried about having to choose a low-sodium diet, unless it becomes a trend when being over my intake level. Astonishingly, my vitamin intake was really good, and I am somewhat surprised by that. There were only two Vitamins I was low in enough to talk about were vitamin C at 69. 19 mg Folate, which was at 273. 60 mcg of my recommendation of 400 mcg. Minerals seemed to be average for me, with potassium, magnesium, and calcium (I have to take extra by pill form) being the lowest out of the eight listest on the report. Calories, calories from fat, and calories from Saturated fat were all low for me as well. I am a guy and unfortutely I do not count my calories, however, I have a cool application on the I-phone that is a calorie counter! The diet analysis opened my eyes and realized that I do not know what I am really doing to my body. My feelings are different after finding out the true facts. Knowledge is the key to a healthier lifestyle, and the diet analysis program has helped a lot. Goals I need to set for myself are balancing out what I am eating, try to learn as much as I can on the subject of nutrition, and be more aware of what options are available to me when I go out to eat during lunch (smaller portions). Those are problems that I would like for my to correct.

Reasons For Being A Successful Student - 879 Words

Going to BCC was honestly my last option, I was that girl that wanted to get out and go somewhere and meet new people. After finishing my first semester I could say I learned everything I needed to know and more from the classes I took. The most important thing I learned from attending BCC was how to be a successful student. Being a successful student means that you go above and beyond what they ask for. It means don t procrastinate on all your homework, hand everything on time and maybe even early, don t be late to your classes, and always come prepared. There are three major steps to being a successful student and they are time management, studying, and test taking. Being a successful student is key especially if you want to succeed.
