Analysis of Solutions Containing Essay

This experiment continues the qualitative analysis begun in Experiment 19. Here we will be analyzing solutions to determine the presence of anions. The same techniques that were used for the cation analysis must be used for the anions. If you have not carried out Experiment 19, read the introductory section before starting this experiment. The major difference between cation and anion analysis is that in anion analysis, a series of separations of the ions from one another is usually not the most efficient way to determine their presence. Instead, only some separations will be made, and the initial test solution will be used to test many of the ions. Refer to the flow chart at the end of the experimental directions as you proceed. First you will prepare and analyze a â€Å"known† solution which contains all six of the anions. Then you will analyze an â€Å"unknown† solution using the same techniques, to determine the presence or absence of each anion. Most of the acids and bases used are very concentrated and can cause chemical burns if spilled. Handle   them with care. Wash acid or base spills off of yourself with lots of water. Small spills (a few drops)   can be cleaned up with paper towels. Larger acid spills can be neutralized with baking soda, NaHCO3,  and then safely cleaned up. Neutralize base spills with a vinegar solution (dilute acetic acid). Some of   the compounds are poisonous. Wash your hands when finished. Solutions containing silver ions and potassium permanganate solutions cause stains which do not appear immediately. If you suspect that you spilled any of these solutions on yourself, wash off with soap and  water. Wear Chemical Splash Goggles and a Chemical-Resistant Apron. Preparation of a Solution for Analysis. Prepare a known solution containing 1 mL of each of the anions to be tested. This solution will be   referred to as the original test solution.  Your teacher will provide you with an â€Å"unknown† solution to be analyzed. Note that the following directions are written for a â€Å"known† solution that contains all of the anions. An   Ã¢â‚¬Å"unknown† solution will probably not form all of the products described in this procedure. You should  make note of any differences as you analyze your â€Å"unknown† solution. Aqueous solutions of all of the anions to be tested are colorless. The positive ion associated with each   of the anions will be either sodium or potassium ion. 1. Separation of the Halides (Cl-, Br-, I-); Confirmation of Chloride. The halides all form insoluble silver compounds. Silver chloride is a white solid, silver bromide is pale cream-colored solid, and the solid silver iodide is light yellow in color. Cl-(aq) + Ag+(aq) AgCl(s) Br-(aq) + Ag+(aq) AgBr(s) I-(aq) + Ag+(aq) AgI(s) Silver chloride is the only silver halide that dissolves in 6 M ammonia, NH3, forming the colorless ion Ag(NH3)2+. If nitric acid, HNO3, is added to a solution containing this ion, the ammonia in the complex reacts with hydrogen ions to form ammonium ions, and the silver recombines with the chloride ions which are still present in solution. AgCl(s) + 2 NH3(aq) Ag(NH3)2+(aq)+ (aq) Ag(NH3)2+ (aq) + (aq) + 2 H+(aq) AgCl(s) + 2 NH4+(aq) Place 10 drops of the original test solution (or unknown solution) in a test tube. Test to see if the solution is acidic. If it is not, add 6 M acetic acid, HC2H3O2, dropwise with stirring until the solution is acidic. Add 10 drops of 0.1 M silver nitrate, AgNO3. A precipitate of AgCl, AgBr, and AgI will form. Centrifuge and pour off the supernatant liquid. Wash the solid with 0.5 mL distilled water, centrifuge and discard the wash water. Add 0.5 mL 6 M ammonia, NH3, to the precipitate. Stir to dissolve any AgCl. Centrifuge, and pour the supernatant liquid into another test tube to test for chloride ion. Discard the precipitate of AgBr and AgI in a container provided for disposal of waste solutions. Add 1 mL 6 M nitric acid, NHO3, to the solution containing the dissolved silver chloride. The solution will get hot and smoke from the reaction with the excess ammonia whether or not silver chloride is present. Test with litmus or pH paper to see if the solution is acidic. If it is not, add more HNO3 until the solution is acidic. The appearance of the white precipitate of AgCl in the acidic solution confirms the presence of chloride. 2. Separation and Confirmation of Bromide and Iodide. In acid solution, iron(III) ion, Fe3+, is a weak oxidizing agent capable of oxidizing the easily oxidized iodide ion to iodine. Bromide and other ions present will not interfere. The nonpolar iodine will preferentially dissolve in nonpolar mineral oil, where it can be identified by its pink to violet color. 2 I-(aq) + 2 Fe3+(aq) I2(aq) + 2 Fe2+ KMnO4 is a stronger oxidizing agent than the iron (III) nitrate and will oxidize bromide, Br-, to bromine, Br2. Other ions present will not interfere. The nonpolar bromine can be extracted into nonpolar mineral oil where it can be identified by its characteristic yellow to brown color. 10 Br-(aq) + 2 MnO4-(aq) + 16 H+(aq) 5 Br2(aq) + 2 Mn2+(aq) + 8 H2O(l) Place 10 drops of the original test solution (or unknown solution) in a test tube. Add 6 M HNO3 dropwise with stirring until the solution is acidic. Add 1 mL 0.1 M Fe(NO3)3 in 0.6 M HNO3 solution and stir. Then add 1 mL of mineral oil, stopper the test tube with a cork stopper and shake for 30 seconds. The presence of a pale pink to purple color in the mineral oil layer (the top layer) due to dissolved iodine confirms the presence of I- in the original solution. Draw the mineral oil layer off the solution with a capillary dropper and discard in the container provided for waste solutions. Add 0.1 M KMnO4 solution dropwise with stirring until the solution remains pink. Again add 1 mL mineral oil, cork and shake the test tube for 30 seconds. The presence of a yellow to brown color in the mineral oil layer due to dissolved bromine confirms the presence of Br- in the original solution. Discard the solution in the container provided. 3. Confirmation of Carbonate. In acid solution, carbonate forms carbon dioxide gas and water. The carbon dioxide may be seen as a   slight effervescence. Carbon dioxide is less soluble in hot water than cold water. When carbon dioxide gas is passed through a saturated solution of barium hydroxide, it readily forms a precipitate of white barium carbonate. CO3 2-(aq) + 2 H+(aq) CO2(g) + H2O(l) CO2(g) + Ba2+(aq) + 2 OH-(aq) BaCO3(s) + H2O(l) If any bubbles were formed when acid was added to the original solution, carbonate is probably present and carbon dioxide is being formed. A confirmation of the presence of carbonate involves reacting evolving carbon dioxide with barium hydroxide to form white, insoluble barium carbonate. Place 2 mL of clear, saturated Ba(OH)2 solution in a test tube to be available for the test with carbon dioxide. Place 1 mL of the original test solution (or unknown solution) in a different test tube. Acidify this solution by adding 0.5 mL of 6 M HNO3. Place the tube in a hot water bath and observe to see if any gas bubbles form. Take a dry Beral pipet and squeeze the bulb closed. Place the tip of the pipet close to (but not touching) the surface of the liquid in the test tube and slowly release the bulb to draw escaping carbon dioxide into the pipet. Put the pipet into the  barium hydroxide solution, and slowly squeeze the bulb, causing the gas in the pipet to bubble through the barium hydroxide solution. This procedure may be repeated. The formation of a cloudy white precipitate of barium carbonate confirms the presence of carbonate ion in the original solution. 4. Confirmation of Sulfate. The test for sulfate is the formation of white, insoluble barium sulfate. This solid is insoluble even in acidic solution. SO4 2-(aq) + Ba2+(aq) BaSO4(s) Place 0.5 mL of the original test solution (or unknown solution) in a test tube. Add 6 M nitric acid, HNO3, dropwise until the solution is acidic. Then add 0.5 mL 0.1 M BaCl2 solution. The formation of a white precipitate of BaSO4 confirms the presence of sulfate. 5. Confirmation of Nitrate. The test for nitrate involves the reduction of nitrate ions in basic solution to ammonia, NH3, using solid aluminum as the reducing agent. When the solution is heated, ammonia gas is liberated. The evolving ammonia gas will turn litmus paper from pink to blue. 3 NO3 –(aq) + 8 Al(s) + 5 OH -(aq) + 18 H2O(l) 3 NH3(g) + 8 Al(OH)4 –(aq) Place 1 mL of the original test solution (or unknown solution) in a test tube. Add 6 M NaOH dropwise until the solution is basic, and then add 6 drops in excess. Use a Beral pipet to transfer the solution to the bottom of a dry test tube without getting the walls of the test tube wet with solution. Add the tip of a spatula of aluminum granules. Place a small cotton wad loosely about halfway down the test tube, but not touching the solution. This is to prevent spattering of the solution onto the litmus paper. Hang a piece of moist red litmus paper (or pH paper) in the tube so that the bottom of the paper is close to (but not touching) the cotton. Now  warm the solution in a hot water bath until it starts bubbling strongly. Be sure that the solution and the cotton do not touch the litmus paper. Allow the solution to cool. A slow color change (within 3 to 5 minutes) of the litmus from pink to blue, starting at the bottom and spreading to the top, indicates the evolution of ammonia and confirms the presence of nitrate in the original solution. Disposal Your teacher will provide a waste container for the solutions used in this experiment. The teacher will add solid zinc and some sodium sulfate to the waste collected. The substances may be safely disposed of using the method in the Flinn Chemical Catalog / Reference Manual, suggested disposal method #11 (procedure B). See the appendix. Discussion In your laboratory discussion include answers to the following questions: 1. The confirmatory test for chloride ion with silver ion is the same chemical reaction used to confirm silver in the cation analysis scheme. Explain what the reaction is and how the initial precipitate is dissolved and reprecipitated. Use equations in your explanation. 2. The procedure for chloride analysis makes use of the fact that AgCl can be dissolved in ammonia, but neither AgBr nor AgI will dissolve in ammonia. Look up the solubility products of AgCl, AgBr and AgI and show how their relative solubilities agree with this fact. 3. Refer to a table of standard reduction potentials to find the values for the reduction of Cl2, Br2, I2, MnO4-, and Fe3+. List the reduction reactions according to the E º values. From the listing determine which of the halides can be oxidized by Fe3+ and which can be oxidized by acidic MnO4-. 4. Explain why it is necessary to test for iodide by oxidation with Fe3+ before the test for bromide by oxidation with MnO4- is done. 5. Write separate oxidation and reduction half-reactions for the procedure used in the test for nitrate ions. 6. In the nitrate test, why must care be taken to keep the moist litmus from coming in contact with the cotton or the solution?

How to Write an Award-Winning Nutrition and Dietary Term Paper

How to Write an Award-Winning Nutrition and Dietary Term Paper When writing nutrition and dietetics term paper, you should concentrate on the issues related to food safety, diet therapy, good hygiene, principles of community health, nutrition assessment, and so on. Your tutor may provide you with an opportunity to select the topics. Also, you may be required to address specific topics related to nutrition, such as animal physiology. The success of your term paper depends on your ability to state and prove your position, the way you articulate your arguments, the way you adhere to stipulated guidelines, and the way you observe term paper writing procedure. Writing a term paper on nutrition is a tedious process, especially when you lack necessary skills and some level of understanding of the basic term paper elements. Regardless of your academic level, writing term papers is a part of the evaluation process that professors use to test your understanding of concepts, your ability to apply them, and think critically. This nutrition dietary term pap er guide provides you with the necessary tips that will help with your paper. How to Formulate the Term Paper Topic that Works Even the best writers find it hard to choose an original topic. Finding a topic for your term paper is the most common part of any writing process. Different strategies can be used to come up with an original topic. Some of them are described below: Brainstorming. The brainstorming process involves thinking and developing ideas about the nutrition concept you explore. Idea development is a common thing at the beginning of the writing process, and it slows down as you go through the process. When brainstorming, note down any ideas you come up with regardless of how irrelevant you think they are to the term paper. Freewriting. For proficient writers, freewriting is like a warm-up that occurs when they first begin to write. It involves sitting and writing whatever comes to mind for the first ten to twenty minutes. It will help you to make your ideas pour out onto the page. Since freewriting is spontaneous, there are plenty of opportunities presenting themselves. Thus, it is likely that you will grab some original topic ideas from there. You do not need to worry about the grammar, the sentence structure, or the viability of ideas at the freewriting phase. Once you are done with freewriting, you can engage in reviewing your writing afterward to come up with original topic ideas. Research. Commonly students think that by starting to read the material they are writing about they can reach to the core of the topic. The problem occurs when the reading keeps the mind too busy to focus on the topic itself. Once you have a potential topic in your head, you can focus on or conduct research to set different angles you can use to approach the topic. Moreover, thorough research helps to find out if a sufficient amount of information is there at your disposal to write a logical term paper. When selecting a topic for your nutrition term paper, ensure you: Pick a topic that will arouse the readers’ emotions; Avoid the topics that have been discussed repeatedly; Select the topics that are not too broad or too specific; Select a topic that makes the audience passionate about it and willing to make a change; Select the topics that are based on current events and trends in nutrition and dietary studies; Choose a topic that states a problem and offers solutions to resolve it; Select a topic that is of great interest to you and the audience. Examples of the topics for nutrition and dietary term paper are the following: The Interrelation Between Blood Lipids and Human Atherosclerosis; The Effects of Dietary Approaches to Stop Hypertension-Style Diet on Nonfatal Cardiovascular Disease; The Effects of Dietary Ghee; Poor Nutrition as the Main Cause for Child Obesity; The Effects of Dietary Arachidonic Acid on the Humans’ Immune Response System. Pre-Writing Tips for Your Term Paper: Steps Our Writers Take Prewriting is a form of preparation done before starting the paper writing process. It involves thinking about your topic, gathering ideas, and making a plan for your project. Using appropriate pre-writing tips can help you complete your paper and put you on the right track when you start writing. You can view this as preparing for your research paper in stages that include selecting a topic, brainstorming, making a list of questions your paper will tackle, and making an outline to help you conduct research and organize findings. The following points offer a few tips to help you start developing your prewriting plan. Select a topic through brainstorming or review a list of topic suggestions. Think about your topic before you start writing. Although you may have an idea of a topic, deliberate about it to understand what you want to write about. Brainstorming will help you to break up ideas into potential topics. Moreover, you are likely to find an original topic you can tackle without writing about a common topic. Once you’re done with that, visualize yourself writing through exploring the things you want to mention about your topic and the way you will collect information about your topic. It is recommended to write brief notes to understand what your topic needs, to think about the sources you will use, and consider when you will work on your content. Engage in free writing and consider answering basic questions about your topic. When freewriting, think about questions your readers would have and check if you can answer them on your own. Thus, you’ll get the idea of how complex your research will be. If you can answer most questions, consider adding unique information to make your term paper interesting. You should also check your tutor’s instructions regularly and take notes on additional actions you may need to take to ensure your paper meets academic requirements. Make an outline. Based on what your term paper requirements are, you should make an outline that features sections your research paper will highlight. You may break up your term paper into three sections and work on each section when you are ready to do your research. When you’ve got the full scope of ideas, you can outline the information you will present in the introduction, the body paragraphs, and the conclusion. How to Craft a Thesis Statement for Your Paper The thesis statement should present the summary of your term paper topic in one or a few sentences. It should also inform the readers about your argument and what to expect. In this case, craft a thesis statement that informs your readers about the subject of your paper and the position you will take in the discussion. Your nutrition research paper should have a strong thesis statement that articulates the unifying theme of your paper. When creating a thesis statement, ensure: It presents the research paper main argument; It provides your position on the argument; It makes a connection between the major argument of your paper and evidence provided in the research paper paragraphs; It provides room for the intended audience to refute the articulated claims. In this case, your thesis statement should present a viewpoint that the readers and the other writers can agree or disagree with. It should also provide reasons for choosing specific claims over the others; It makes a limited, clear, and accurate assertion that should be explained and supported through scholarly evidence; It has a specific point that provides the direction of your paper’s argument; It is not too big for your paper such that it would be impossible to explore every aspect of your claim; It presents an argument that can be proven or argued against. Ensure your intended audience does not instantly accept your thesis statement; It refers to the methods you will use to provide evidence to support your arguments. Recommended Structure of Your Nutrition Term Paper A paper in nutrition and dietetics should consist of at least three parts, namely the introduction, the body, and the conclusion. The body segment has further divisions that can be presented in the form of paragraphs. These divisions focus on the presentation of arguments and counter-arguments, and a response to the raised objections. Introduction. The opening paragraph of your term paper serves as an introduction to it. The introduction should present your topic, the arguments discussed in the paper, your intended objective, and should contain a thesis statement and an explanation of it. If you do not have a clear picture of your paper’s organization at this stage, write the entire paper and compose the introduction once you finish the main body. In this case, compose the other sections of the paper first, and come back to (re) write the introduction so that it reflects what your term paper is all about. Where necessary, define the key terms in your thesis statement. These terms should define your paper and provide the scope of it. Body. The body of the term paper should present your argument as stipulated in your introduction. The arguments should be given in paragraph form. This implies that each paragraph should focus on one main argument. Moreover, each paragraph should have a topic sentence that makes a claim for the paragraph. The topic sentence should be in-line with the term paper’s topic and the thesis statement. The subsequent sentences in the paragraph should provide evidence that supports the noted claim. In cases where the body section should contain subheadings, it is important to group themes in a way that ensures they provide a systematic analysis of appropriate content for each subheading. The body should also have paragraphs that present arguments that support the thesis. The arguments constitute the greater part of the term paper. In presenting your term paper arguments ensure to: Use compelling premises logically; Present the possible arguments in paragraphs; Discuss each argument in its own paragraph along with evidence that supports the argument; Ensure your paragraphs demonstrate your understanding of the nutrition topic you are tackling; Provide empirical and theoretical support for the presented arguments and do not repeat them. A recommended structure for your term paper body section can appear as indicated below: Heading 1: History of the nutrition issue. You may include past attempts and solutions. Heading 2: Extent of the problem. Who is affected? What impact did it have? Heading 3: Effects of the problem. Heading 4: Possible future solutions. Conclusion. This part of the term paper should present your concluding remarks. Restate your thesis statement and summarize the major points of your research paper. An appropriate outline for your term paper should appear like this: I. Introduction II. Body: Paragraph 1 Paragraph 2 Paragraph 3 Paragraph 4 III. Conclusion Post-Writing Tips for a Triumphal End Once you are done with writing part, take a break, preferably one day before engaging in the research paper review. This will provide you with a new outlook once you go through your paper. If you don’t have a day, take at least a one hour break. You should review paragraph issues, sentence-level issues, and content coherence.

Comparison of the Songye Power Figures and the Fang Reliquary Figures

Comparison of the Songye Power Figures and the Fang Reliquary Figures Introduction The beauty and uniqueness of African artwork remain distinctive from the historical ages to date. One of the most common artwork is that of sculptural designs that has individualism and highly values content that forms today’s historical analysis.Advertising We will write a custom essay sample on Art of Africa: Comparison of the Songye Power Figures and the Fang Reliquary Figures specifically for you for only $16.05 $11/page Learn More What is even more interesting of the sculptures is the introspective draping the sculptural works. There is mystical aspects inclining to the ancestral believe, worship and realm of the unknown. This paper forms a comparison as well as contrast between the Songye Power figures and the Fang Reliquary figures. Songye Power Figures Style of Songye Power Figures This is a bilaterally symmetrical sculpture furnished with textural scales and an aesthetic form to reflect devotion. Entire surface of the Songye powe r figure draped with metals, wood, feathers and other material linings fastened systematically to produce a balanced appearance. However, the Songye power figure originating from the Republic of Congo appears more distinctive with the indentations on the eyes, mouth and stomach areas that lack the tack lining. Like other similar traditional figures, Songye’s empty areas are stuffed with symbolical substances such as plants and animal remains or minerals around the geometrically outlined limbs, chest area, head and neck. Copper nails with turret heads were common material featuring on the sculpture like other similar sculptures such as the Fang Reliquary sculptures. The finishes of the sculpture include beaded necklaces and naturalistic bands made of animal hide and pelts. Like most traditional figures, the pedestal base of the sculpture was also an integral section of the design. The figure below illustrates the sculpture. Songye Power figureAdvertising Looking for e ssay on art? Let's see if we can help you! Get your first paper with 15% OFF Learn More Purpose of Songye Power Figures The mouth of the Songye figure symbolically presents the offerings to the ancestral spirits who bestows fertility and provides protection against illnesses or misfortunes. Like other sculptures, the purpose of this figure was to strengthen the diviner’s powers of healing and maintain the societal wellbeing. The diviner recommend the Songye sculpture for the patients treated using the herbal medicine, so that it can strengthen the healing process through divine protection. The large sized sculpture were communally owned but small designs customized for special personal needs such as private prayers reminiscent of protection against the evil spirits, heal ailments and communication to the ancestral spirits were available. Like the other traditional sculptures, Songye provided divine powers for success for common endeavours such as hunting or ga thering. Songye also had the role of protecting personal object and devotion. One special need that the figures addressed was enhancing fertility through support of conceiving or preventing miscarriages. The genitalia of personal Songye would indicate the preferred gender for the first child. The figures were also an empowerment to the community such as illustrating the ideal masculine leadership style and like other similar sculptural designs, Songye were idiosyncratic to represent regional reputation. Tribal Life of Songye Power Figures Similarly, to other sculptural works such as the Fang Reliquary, Songye Power Figures are sculptures commissioned to top leaders such as chiefs or village elders, whose wishes are to benefit communities. Design of the sculpture also comes as an ancestral appraisal symbol to assist during crisis. This meant that everyone in the society had to seek the divine intervention through sacrifices and special appeals to the sculptures. Other sculptures have special aspects that unite members just like the Songye sculptures. They share various traditional functions such as protection against enemies, illness, witchcrafts and procreation matters. Fang Reliquary Figures Style of Fang Reliquary Figures On the other hand, the fang reliquary sculptures made from woodcarvings and metals have glittering surfaces and patina appearances especially after palm oil applications during rituals. Unlike other sculptors, the Fang Reliquary sculptures have daring human obstructions and receptacles of ancestral relics, thus referred to as the guardian of sacrosanct.Advertising We will write a custom essay sample on Art of Africa: Comparison of the Songye Power Figures and the Fang Reliquary Figures specifically for you for only $16.05 $11/page Learn More The relics are made of human bones. The enhancements idolized the ancestral forehead figures due to believe that force saturates in the head. The reliquaries made from joint ba cks preserved the relics and the figure provided guardianship through the symbolic trace of ancestral protection. The sculpture is arguably the main influence of traditional wooden sculptures. It has an absolute physic appearance and in Gabon, the female sculpture emanates vitality. The fang reliquary figures have three distinct groups, one with a head crafted on a long neck, full sculptured figures and half figures or busts. The figures are either stand-alone or seated. Unlike other sculptures, the spherical but naturalistic of Fang Reliquary brings out sophistication from the simple carvings. The neck is often round with the hands placed in diverse styles such as in front of the body, chest, and holding objects or placed on the knees for the seated figure. The navel is a cylindrically exaggerated protruding carve-out. The legs are shorter to give a stunted appearance, while the eyebrows and fore head projects some contours and arcs around the nose area. The eyes were made of round ed metal bits. These aspects making the sculpture unique compared to other forms such as the Songye sculptures as shown below. Fang Reliquary figure Purpose of Fang Reliquary Figures Unlike Songye sculptures, Fang Reliquary sculptural work was to protect people from the spirits of the deceased. The figure was sacred but lost the value of sacredness once separated from the receptacles or repository chest of relics. Unlike other religious statutes, it also underwent sacred ritual of distraction after losing sainthood, which involved prayers, sacrificial offers to the ancestors and libations such as pouring of alcoholic drinks in honour of deity. Tribal Life of Fang Reliquary Figures Fang Reliquary sculptures are universal and blends the environment, other forms of tribal rituals, believe and communal characters better than other sculptures. The figures are mainly in seated positions on top of the bark boxes that held sacred relics thus depicting the guardian figures better than the S ongye sculptures. A clear distinction from other forms was that it brought out youngster aspects as an emphasis over continuity of life.Advertising Looking for essay on art? Let's see if we can help you!

Both the art forms have a way of creating a blend between the unborn, the living and the living dead and represent religious symbolism. This is a clear indication that the African artworks were mainly based on sacred believes and sacrificial practices.

6 successful ways to start your workday

6 successful ways to start your workday Do you have a hard time hitting the desk running, so to speak, on any given work day? Try following some of these strategies to jumpstart your work mornings and make yourself more productive and engaged from the get-go. 1. Establish a pre-work routine at home.First, you have to lay a solid foundation, which means a good night’s sleep. Then, when you hopefully wake up well rested, throw in a nice stretch or short bit of exercise. Get your blood moving- whether you have five minutes to spare for some yoga or can squeeze in 30 minutes of a solid workout. You’ll feel more awake, more grounded, and more capable. Then eat something with a bit of protein that will fuel your morning. Finally, if you’re a caffeine person, have your coffee or tea.2. Dress to feel and perform your best.You don’t have to go formal to â€Å"dress the part.† If you work from home, at least change out of your pajamas to differentiate your lounging self from your working self. If y ou don’t, aim for work clothes that make you feel comfortable and empowered.3. Start on time.Whether your commute is the five steps it takes you to get from the kitchen table to the couch or 45 minutes of driving, busing, or biking, arrive at your desk on time. To perform your best, consider â€Å"on time† to be five minutes early–that gives you time to collect your thoughts and set yourself up for the day ahead.4. Take a moment to just think.A moment of peace can be a moment well-spent- every morning pause to have a nice, mindful think about how things are going, what you’ve been accomplishing, and what you’d like to get done that day. Reacquaint yourself with your to-do list. Pause for a second and engage. Your work day will be much more bearable this way because you  will be in charge of managing the day (and not the other way around). Map out your day, allowing for small adjustments here and there.5. Get comfortable.Figure out the most ideal work set-up for your productivity. Maybe that’s a standing desk, or an exercise ball, or a lumbar support, or a footrest under your desk. Make sure everything in your workspace is de-cluttered and positioned to make yourself physically capable of sitting there and doing what you need to do.6. Eliminate distractions.Devise a system that will make you less vulnerable to interruptions. When you sit down for the day, turn off notifications, put your phone in a bag or a drawer, and focus- at least for long stretches of time. If it helps, set a timer to help you keep break time, mindless task time, and productive project time separate. And do yourself a favor: don’t check your email all the time. Set yourself designated times instead.The main takeaway from these tips is to remain mindful and put systems in place. If you establish a morning routine and stick with it for at least 2 weeks, these good habits will soon become the norm!

Need to find a trending topic in the field of civil engineering Research Paper

Need to find a trending topic in the field of civil engineering - Research Paper Example The production involves an additive process different from the machining techniques that uses subtractive processes such as drilling and cutting. 3 D printing is exclusively done from digital models. The impact of 3 D printing is enormous and continues to shape the civil engineering sector. 3 D printing is being used in civil engineering in two main ways. Firstly, the technology has taken toll in prototyping. Engineers, architects and contractors have relied on 3 D prototyping in the recent times to manipulate designs and digital models to materials that are used in construction. It has been established that 3 D prototyping is an efficient, fast and cost friendly method in the fabrication of complex designs when high definitions are required. Prototyping enables production of high quality maps and plans that have well defined terrain and surface features. Secondly, distributed production has been utilized in the industry in manufacturing some of the raw materials. It takes into use d ispersed facilities used in manufacturing and are coordinated using information technology platforms. This aspect has boosted the activities of civil engineering industries that have a wide range of geographically separated activities. It reduces shipment and freight costs for the company. Engineering jobs have and will be affected by the technology. 3 D printing technology has been reported to contribute to job cut in the engineering sector (Frick 1). The automation in printing of models and the efficiency that accompanies has made many clients to seek 3 D printing services. For the last twenty years, 3 D printing companies in the world have demonstrated tremendous growth. Materialise, one of the companies that has retained the convectional methods, has employed approximately nine hundred people of which around eight hundred and fifty are engineers who play the role of designing projects’ processes. This number of engineers is so big compared to the companies that have embra ced 3 D printing technology such as the New York based 3 D printing manufacturer, Shapeways that has less than one hundred employees (Frick 1). The customized design apps that are supplied by Shapeways make the role of engineers to be limited hence the smaller number of engineers that are required. In addition, the apps are capable of facilitating creation of more complex structural models. The additive strategy adopted by 3 D technology has many benefits over the convectional subtractive manufacturing methods. The results of the technology are evidenced by the ability to do local production; the only requirement is to have the digital designs in place. The designs are distributable through digital platforms, thereby can be retrieved through a networked computer system. Stocking is another problem that is avoided. Conventionally, engineering companies have been producing models that are kept in the stores, with 3 D technology, production is based on demand. Another advantage of the technology is the ability to print wholesome products instead of joining parts together; this reduces the need for assembling while facilitating the production to be made at the point of demand. A deviation from the convectional manufacturing where engineering products were made in a particular fixed way, 3 D printing technology allows for customization of a product according to the specific needs of the client. In addition, the speed of production is highly improved, hence saving on the time required for the

Does Rousseau's conception of the General Will safeguard against Essay

Does Rousseau's conception of the General Will safeguard against tyranny or promote it - Essay Example 5). Rousseau has tried to make conciliation between the individual freedom and the authority of the state. Every man is born free and himself is his own master. No man can make any other man his subordinate without the free consent of the later (Rousseau, Book IV, 1923). The paper attempts to address the question whether the General Will can safeguard against tyranny or promote it. The social contract Man is born independent and enters into the society â€Å"by an act of free will† (Rousseau, 1917, p.28). The term ‘social contract’ directs towards an arrangement in which the common mass submit the sovereignty to the government or an authority for the maintenance of social order in the country. Through this they become â€Å"an indivisible part of the whole† (Ramgotra, 1994, p. 820). Through the social contract a polity is created, that acts as per its general interest (Trachtenberg, 2002, p.4). Thus, a law is proposed in the popular assembly and all the cit izens give consent to the laws. The right of voting cannot be separated from any individual citizen in any act of sovereignty (Rousseau, Book IV, 1923). Rather, one becomes a citizen through his co-authorship in the law-making (Parra, 2010 p. 15) Each individual has the inherent right to state his own views and make proposals. It is argued that, if he has a particular interest which is different from the common interest, the individual is actually made to become free on being forced to follow the interest of the majority. This is on the basis of a supposition that the vote of the majority binds the rest of the mass and all the qualities of the majority are reflected in the General Will. â€Å"The constant will of all the members of the State is the general will; by virtue of it they are citizens and free† (Rousseau Book IV, 1923). The society so formed has been termed by Rousseau as â€Å"people† (Rousseau, 1997) The General Will and common good In this context the que stion arises, that how, the people who do not agree to the law are considered free as well as subject it at the same time. The existence of opponents does not invalidate the law; rather, they prevent themselves from being integrated into it. From Rousseau’s point of view, the General Will always tends to support the cause of public advantage and by making the citizens to follow the law that looks after the good of the community, they are actually made free. When a new law is needed to be issued, the necessity is seen as universal. The man who proposes it merely says what the others have already felt. Hence the situation of questioning the law is not expected to arise at all. He rests assured that the others will support him in his action (Rousseau, Book IV, 1923). The civil association is mostly a voluntary act. When the law is proposed, it is not asked of the citizens whether they reject or approve of it, but it is checked whether the law conforms to the general will, assumi ng that the general will is the will of the people at large. So when the individual citizen holds a view that is different from the common will or is unwilling to give consent to the new law, it proves that the person is mistaken. Any true man would opine in the similar lines as the general will that leads towards common good. Either his opinion is guided by a selfish interest or what he thinks to be the general will is not so. No individual rights can be defiant of the general good. Had his

Landscape art in Chinese traditional painting - Assignment Example The essay "Landscape art in Chinese traditional painting" explores the landscape art of China. The period that was referred to as the Tang Dynasty experienced many landscape paintings. These kinds of paintings were mainly done on mountains. This kind of painting had a style that was called the shuimohua whose main intention was to represent the emotion or the look of the atmosphere that indicated the nature’s â€Å"rhythm†. As time went by towards the end of the Tang dynasty the use of landscape painting slowly started changing and it was now viewed as a way in men would communicate with the world through the paintings. Apart from nature, these paintings also conveyed a number of themes in social, philosophical, or political areas. Thus with the closure of the Tang dynasty period more focus of these paintings and the artists were majorly on the world nature. Poets and painters in the Chinese traditional arts would go into the mountains to find something to represent in their drawings. Another period called the Song Dynasty that happened between 960 and 1267 saw the rise of different expression of landscapes. Long distances would be represented by use of blurred outlines, mountain contours represented as disappearing into the mist, and nature would be treated with certain kind of impression. The concern of the artist was on how to represent the peace in human beings and nature. This is eminent in the Taoist and Buddhist concepts. In the early Song Dynasty the artists would represent.
