Research Paper Topics for HR Topics

Research Paper Topics for HR TopicsThis article will briefly discuss some good HR topics for a research paper. I believe these topics can be used in any type of research paper, but I do not think they are well known to many people.The first thing to consider when writing your paper is to determine if the topic you are going to write about is HR related. Most people have little knowledge about the HR department. Therefore they cannot write with complete knowledge of the subject matter.First, the subject you choose is going to require a number of assumptions that you should make so that your research paper appears to be well researched and you can properly explain the details to the reader. You will need to make a choice between two choices here:Since the subject matter is quite involved, it is also necessary to spend a considerable amount of time preparing for the writing. Unfortunately, there is no way to get through all the detail needed for the paper without proper preparation.Befo re you can begin researching for your research, you will want to understand what the subject matter is. For example, if you are researching the causes of suicide, you must be able to answer the question: What caused this person to commit suicide? To be able to answer this question, you will need to identify who the person was, what the person was doing before he or she committed suicide, the time of day he or she did it, the type of suicidal activities the person was engaging in, etc.Another topic that you might consider writing about would be HR subjects. It is a common misconception that all research papers on HR is pointless. However, studies show that one of the more common problems with research papers is that they are written poorly and are also incorrect.As stated above, the most important thing to remember when writing a research paper on HR subjects is to be able to accurately answer the question 'What caused this person to commit suicide?' Many times, the task of writing t he paper is made easier if the researcher has a good HR background and has spent considerable time researching the HR department.Another thing to consider when writing a research paper on HR subjects is to make sure that the paper presents the most accurate information possible. Too often, when we research topics for research papers, we will try to use our own biased opinion to support our own bias. This is not something that should be done when writing an HR related research paper.

Steam Distillation Sample

Steam Distillation Paper Water was largely used as a solvent. A polar solvent used was Decontaminated. The drying agent used was Calcium Chloride. An acid and a base used were hydrochloric acid and Sodium Hydroxide, respectfully. The equipment used were a thermometer holder, separators funnel, classes adapter, 3-way adapter (distillation adapter), triple neck round bottom flask, west condenser, vacuum adapter, Erlenmeyer flask, mall 50 ml beaker, Bunsen burner, rubber tubing, clamp holder extensions, and graduated cylinder. For both parts of lab 4, the heating source was the hot plate, the substances were heated in a mall Erlenmeyer flask, filtered using filter paper and a funnel tit a neck, beakers, vacuum flask for additional filtration, and an electronic scale for weighing the crystals. The solvent used for both parts was 95% Ethanol that was also dripped on the crystals for purification. Ten tablets of aspirin were used in part one. Two grams of impure benzene were used in part two. Procedure: Lab 3 involved an intricate lab with many steps. We began by obtaining 75 grams of cloves and stuffing them into our triple neck round bottom flask.

Into the Classes adapter went a separators funnel in one neck and a 3-way adapter in the other neck. The Separators funnel was filled with 50 ml of water. A thermometer and its holder were inserted atop the 3-way adapter for vapor temperature measurement. The side of the 3-way adapter was inserted into a west condenser, which itself was inserted into a vacuum adapter. The vacuum adapter was allowed to drip over an Erlenmeyer flask for collection of distillate. The entire setup was supported by clamp extensions holders attached at the neck of the triple neck round bottom flask and the vacuum adapter for axiom stability and minimal leakage of vapors. The Triple neck flask was elevated over a Bunsen burner as a heat source. The water in the triple neck flask was brought to a boil, while doing our best to keep it from foaming. The aim here was to distill 60 ml of distillate. As soon as we collected close to 30 ml of distillate we added an additional 50 ml of water into the triple neck flask from the separators funnel to keep the cloves submerged. Once the entire 60 ml of distillate was collected we needed to rid it of its water content. We transferred all of the distillate to our empty separators funnel. We added 15 l of Decontaminated to the separators funnel, inverted it (notice two layers forming), let the pressure out, and drained the organic material that was located at the bottom layer of the funnel into a separate collection beaker. This was done three times. For separate experimentation and reference of weight comparison a 5 ml sample of the not yet pure Gudgeon drawn from the collection beaker. After drying with Calcium Chloride the Decontaminated was boiled out on a hot plate, the remaining impure Gudgeon was weighed, and stored away for later experimentation. The remainder of the impure Gudgeon was treated with Sodium hydroxide to deportation the Gudgeon. This was done three times in the separators funnel adhering to the same principle of inversion and releasing the build up in pressure. However, from the two layers formed we expel the lower Decontaminated layer and kept the top aqueous layer each time. Afterward, the remainder of the depredation Gudgeon in the aqueous layer was acidified with Hydrochloric acid and tested for pH value with a piece of litmus paper. Adding 15 ml of Decontaminated three times, inverting, and draining the bottom layer each time then extracted the Gudgeon. To evaporate the Decontaminated we oiled the Gudgeon-Decontaminated mixture on a hot plate in a collection jar. The pure Gudgeon was then weighed. In part 1 of lab 4, we obtained ten tablets of aspirin to purify and 10 ml of 95% Ethanol to be our solvent. The tablets and Ethanol were mixed in an Erlenmeyer flask and heated until a gentle boil. The contents were then swirled to prevent bumping and promote even dissolving. We aimed for a clear liquid with white solid matter floating. As soon as this was achieved the contents of the flask was filtered through a funnel with a neck into a small beaker and allowed to cool to room temperature. While filtering we kept in mind not to allow any of the floating solid into the filtrate. In the process of cooling we watched out for crystallization. Once the beaker cooled to room temperature, to speed the process of crystallization, the beaker was immersed into an ice bath. After a few minutes, we believed the crystallization was at its maximum. We filtered out the crystals and allowed them to dry atop a vacuum flask on filter paper in a funnel. Air was continuously sucked out to promote drying. To aid the drying process the crystals were washed with drips of ethanol and evenly distributed across the liter paper with a spatula. After a wait time of around 10 minutes, we scraped the dry crystals of the filter paper and weighed them. All utensils were cleaned and made ready for part 2 of lab 4. In part 2 of lab 4, we had a similar process with some difference in solutes. We obtained 2. 0 grams of impure benzene and mixed it with 10 ml of Ethanol. The exact same process in part 1 was repeated in part 2. However, our aim in part 2 was to see a clear liquid with black powder floating, unlike that of part 1 . An additional difference was that we saved our crystals in part 2 for further experimentation at a later time. Class notes: Steam distillation is an ideal method when using two compounds that are immiscible (i. . , water oil or Benzene water). Benzene being the organic solvent that is non-polar and water the inorganic solvent that is polar, creates a dilemma since the two can-not be mixed together. When vaporizing something the vapor pressure must equal the applied pressure. This results in liquid turning to gas. If two immiscible compounds have the same vapor pressure then they will have the same boiling poin t. Another example would be water naphthalene, in which water depresses naphthalenes boiling point. When water boils it creates steam. This steam can be used to pick up particles. One can use steam distillation to pick up immiscible compounds. In our case, the solvent is water and the solutes are the cloves (potentially Gudgeon oil). Gudgeon oil can be used as an anesthetic. To release the contents of the cloves we can boil them. We can implement the Gaffing principle of heating the hell out of it. When a cell is heated at extreme temperatures it will else, resulting in the release of its inner contents. Gudgeon is an organic molecule consisting of a benzene ring, hydroxyl group, and methyl group for the most part. In addition, it is a derivative of phenol. The cloves also contain the derivative of Gudgeon, which is Acetic Gudgeon. Gudgeon has a very sharp boiling point of 255 degrees centigrade. One can purify a solid by the process of crystallization. To begin the process of crystallization, pick a solvent that will not dissolve the chosen solute at room temperature, but only when the solvent ; solute mixture is brought to a boil (reflux). Some common examples of solvents used with different boiling points are Ethanol, Citronella, Hexane, and Toluene. One should try to avoid water as a solvent due to its inorganic ; polar properties. A property desired from a solute is not to dissolve at room temperature, but only in a refluxing solvent. If the solute is not dissolving, gradually add more solvent to the refluxing mixture. Once no more solute is visible in the mixture that is a good indicator that it has all dissolved. Sometimes after the solute has dissolved there might be some contents still visible and floating in the solvent. These would normally be known as impurities (ex. Charcoal). Organic compounds are usually colorless or yellow. To rid the solvent of unnecessary impurities, one should quickly filter the mixture as soon as the solute has disappeared (dissolved). After filtration, one can promote crystallization by allowing the mixture to cool to room temperature. If there are not too many crystals visible at room temperature, one can place the solvent in an ice bath to aid the process. The crystals can be obtained by simply filtering them out of the solvent. Ethanol is great for washing and drying the crystals, since it will not dissolve them at room temperature. Our solutes in this lab are Aspirin and impure Benzene. An active ingredient in Aspirin is Ecstatically acid and the inactive ingredient is binder. Aspirin will not dissolve in Ethanol at room temperature. However, if one should bring Ethanol to a reflux, aspirin can be dissolved. Once aspirin is dissolved it will leave behind its binder floating. Binder should be filtered out. Each tablet of aspirin contains 325 MGM of active ingredient. We shall use 10 tablets, equating in ideal conditions to a 100% yield of 3. 25 grams. When using impure Benzene, Ethanol can be the solvent too. When Ethanol is brought to a reflux, the Benzene will dissolve and leave behind TTS impurities. The impurities remaining are charcoal due to the black color of the floating residue. The impurities are easily filtered out with a funnel and filter paper. Observations: In the steam distillation lab, our first observation was the color the water ; clove mixture when brought to a reflux. The mixture turned a dark brown color. Then once the distillation process was underway, we witnessed the distillate collected had a white milky substance floating. The milky substance was oil and the rest was water. We added Decontaminated to the mixture and noticed the oily layer separated from the water. The organic layer that contained the oil descended to the bottom and the inorganic layer rose to the top. Once we extracted the organic layer, we wanted to dry it with Calcium Chloride. This process yielded white particles resembling little Styrofoam specks floating on the surface of our organic extract. After extracting the chemically dried mixture and boiling out the Decontaminated, we treated the mixture with Sodium hydroxide. This reaction yielded two layers. The two layers consisted of Decontaminated on the bottom and an aqueous oily white layer on the top. We acidified the engaging aqueous oily layer with Hydrochloric acid and tested the pH level with litmus paper that turned pink. Once again the mixture was treated with Decontaminated, separating the contents into two layers. We extracted the organic layer and boiled out the Decontaminated yielding a yellow thin film of Gudgeon oil. In the crystallization lab, our first observation was the milky liquid that appeared once the aspirin began to dissolve in the refluxing Ethanol. Once all the aspirin dissolved, white binder residue remained floating. The binder was then filtered out, leaving behind a clear liquid. Crystallization began once the liquid started approaching room temperature. The greatest noticeable proliferation of crystals was when the mixture was placed in an ice bath. When the crystals were filtered out of solution they appeared white in color. As for the impure benzene crystallization, we observed dark impurities (charcoal) floating on the surface of the solution. Once the impurities were filtered out, we noticed a yellow clear liquid remaining. The crystals extracted by filtration from the yellowish liquid were yellow themselves. Results: 75 grams of cloves yielded . 05 grams of pure Gudgeon oil. 0 tablets of Aspirin totaling to 3. 25 grams of Ecstatically acid gave us a yield of . 94 grams. 2. 02 grams of impure Benzene gave us a yield of . 03 grams of pure benzene. Discussion: Through steam distillation, 75 grams of cloves (potential Gudgeon oil) gave us a yield of . 05 grams of Gudgeon oil. This creates a question in our mind. How come our yield was so minute? A few factors could come into play that would diminish our yield capacity. Factors such as a lack of control and impure chemicals used. The lack of control in particular would be poorly fastened joints or leaky hermetic holders allowing the escape of vapors, no vacuum-sealed system to protect the experiment from temperature fluctuation, impure glassware that could potentially contaminate the experiment, the poor reflux of the water/clove mixture resulting in the reduced pickup of Gudgeon by the vapor particles, and a poorly calibrated weighing apparatus. Impure chemicals such as reagents and solvents can play a factor in the pure isolation of Gudgeon from the cloves too. Impure Calcium Chloride would impede the drying process, Decontaminated would not separate enough Gudgeon out of the water, Sodium Hydroxide would to deportation enough Gudgeon, and Hydrochloric acid would not acidify enough back for Decontaminated to separate. In the crystallization experiments, 10 tablets of aspirin gave us . 4 grams that seemed like an extremely minute amount compared to the ideal 3. 25 grams we could have isolated in a perfect experiment. In the crystallization of Benzene, from the 2. 0 grams of impure Benzene we isolated only . 03 grams. We begin to wonder what could have gone wrong. Once again, a lack of control and impure chemicals used seemed to be the perfect suspects in our poor results. Some aspects of a ace of control would be not enough desired solute dissolving with our solvent, non- dissolved solute being filtered out with our residue of impurities, during filtration crystallization might have occurred causing crystals to be filtered out of the solution, room temperature might have been too low, which caused a rapid temperature drop that trapped impurities, and parts of the crystals might have been lost during the drying process within the vacuum flask. Lastly, the solutes or solvents used might not have been entirely pure resulting in poor isolation of our desired substances.
