Is The Us Healthcare System Truly Reflective Of A Free...

In the cold winter season, more people are going to come down with the flu or pneumonia causing an increase in demand for certain antibiotics and medical care (supply) necessary to treat these ailments. If physicians and/or hospitals do not increase their supply, this will cause a shortage in medical care available meaning the price for care will increase. This is, at its very basic, an example of supply and demand. Introduction Is the US Healthcare system truly reflective of a free market economy driven by supply and demand? Initially, one would be inclined to think yes. In an ideal world, a free market is one which is driven by individual innovation and the concept that hard-work and ingenuity will be bestowed with success. Indeed, the biggest advantage of a free market is that it places the power of choice into the hands of the people. There is freedom to choose how you want to spend your money, what you want to spend it on, and whom you want to spend it on. Do you want to see a physician regarding a yearly physical? Open the yellow pages. You will more than likely find over 100 general practitioners in your immediate area to choose from. Do you want to spend your money on preventative care, early screenings, vaccinations, etc? Or do you want to spend your money on medications after you are diagnosed with an ailment? The main idea behind a free market is that prices will regulate themselves. In regards to the US Healthcare system, it is questions likeShow MoreRelatedMarketing Management 14th Edition Test Bank Kotler Test Bank173911 Words   |  696 Pagesproducts are standardized.

I Needed For The State And The Restoration Of The Monarchy

When it came to reforming her own government, she made sure to surround herself with those that actually had the best interest of the territories in mind. Some of those she credited with her success as a ruler were, Johann Christoph von Bartenstein, Count Friedrich Wilhelm von Haugwitz, Emanuel Silva-Tarouca, and Ignaz von Koch. She wrote, â€Å"Bartenstein and Haugwitz gave me what I needed for the State and the preservation of the Monarchy.

Use of Adobe in Cyprus Free Essays

string(90) " dry during summer where the demand for airing is extremely demanded inside the edifices\." What is Adobe? Production, Application A ; Features Adobe is a composite edifice stuff made with dirt and straws. Needed sum of H2O is added to dirty and straws which is traditionally crushed and squezed by pes, to blend the stuffs making clay. In some parts, droppings is used alternatively of straws. We will write a custom essay sample on Use of Adobe in Cyprus or any similar topic only for you Order Now Straws are used to adhere the bricks together. It besides allow the bricks to dry every bit. Some experiments show that utilizing straws in adobe bricks make them more immune for clefts. Dung is chiefly used to avoid insects. The mixture is so casted into wooden frames ( normally 30cm ten 45cmx 6cm ) .It is compressed within the wooden frames to forestall the spreads, doing it heavy and strong. Excess clay is glanced off the frames to do a level surface for the bricks. Wooden frames are removed and adobe bricks are left to dry in a level surface, under the Sun for a few yearss. It is a low-priced and easy to do stuff which was widely used all around the universe extensively in Egypt, Sudan, Middle East and Asia Minor. As it is an earth stuff, it is suited for semi-arid climes where summers are hot and dry and winters cold and wet. It has a high thermal mass which is defined as the ability of the stuff to absorb heat. It helps to stabilise the inside temperature of the edifices. Main natural stuffs of adobe can easy be found locally. Soil types and colorss depends on the vicinity and that is the chief ground to see different coloured adobe edifices in different countries. Load bearing walls made from adobe bricks are normally 45-50cm broad. Minimal breadth should non be less than 30 centimeter. Adobe walls carry their ain weight into foundations so there is no demand for other sturctures to transport the burden of the walls. Normally, 80-100 centimeter high rock walls are built as a base for the adobe walls to forestall the affect of land humidness on adobe bricks. As there are non any other constructions to transport the adobe walls, land is dug for the termss. The deepness of the excavated country depends on the local features of the land and the frost degree of the dirt. The misguided apparatus of the foundations might do clefts on the walls. Courses of adobe bricks are lined horizantally and binded together with clay howitzer to organize the adobe walls. Mud plaster which is a breathable stuff that can let the wet of the adobe walls to vaporize ; is used to stick on the first bed of the adobe walls. Fine grained straws are added where straw fibres increase adhering and to obtain a smooth surface. Mud plaster is a lasting stuff but the concluding coating of the wall is made by stick oning calcium hydroxide based paste which is a water-repellent stuff to protect the structural feature of the adobe. As it is an earth stuff, one-year fix is recommended. Worn surfaces are replaced by clay howitzer and plastered once more. This procedure is normally carried out during fall. In adobe houses, the breadth of the edifices do no transcend 4m ( 13ft ) by and large. The infinites are largely rectangular and in some instances they might be square shaped. It is recommended to construct maximal two floors with adobe. Ceiling beams which were normally wood, are placed parallel to the short side of the rectangle with 30-40cm intervals. For these beams, cypress tree was normally used in Cyprus. Bushes or reeds were placed above the beams or in some instances reeds in the signifier of mats might be used if available. On top of this bed, 20-25 centimeter midst clay is casted and compressed by a rock roller. This type of roofs need one-year fix, which normally carried out in fall. If the roof is build with a incline, tiles are used to cover the clay bed. This will cut down the scratch of the clay and reduces the demand for care. Use of Adobe in Cyprus Adobe is a common edifice stuff in Cyprus from early ages. Building stuffs might change in different parts, such as Kyrenia and Paphos ( which are coastal parts of the island ) rock was used to construct shelters. In the fields and foothills, adobe was widely used. The usage of the stuffs depended on the regional handiness and climatic factors. As adobe is an insulating stuff, bulk of the houses were build utilizing adobe. Mesaoria vale which is located between Kyrenia Mountains in the North and Trodos Mountains in the sou’-west of the island, is an aluvial field where most of the adobe edifices can be seen. Reports on dirt studies in Cyprus shows that there are chiefly two types of dirt in the island. One is ‘deep soils’ which can be found in fields and 2nd one is ‘shallow soils’ which can be found in mountain and semi mountain countries. ‘Deep soil’ consequences show that % 60 of the dirt in fields is clay. Large sum of the field lands is calcareus with Ca carbonate content up to % 40-60. Limestone is a sedimentary stone which includes high degrees of Ca carbonate. Limestone is processed in different phases to bring forth calcium hydroxide. Including insularity characteristics of adobe, suited ingredients can be found locally around the island which are dirt with high clay content, and limestone to bring forth calcium hydroxide. Adobe bricks are dried under Sun where limestone and roof tiles are baked in local furnaces by utilizing wood or fuel. This makes adobe a sustainable and natural stuff. Limestone was besides used to construct patio walls. Nicosia is located in the Mesaoria vale where adobe edifices can widely be seen. After the declaration of independency of the island in 1960, concrete edifices started to lift over the island. Nowadays, little sums of Earth edifices are built around Cyprus. Cyprus is hot and dry during summer where the demand for airing is extremely demanded inside the edifices. You read "Use of Adobe in Cyprus" in category "Essay examples" Privacy was an of import factor on determining the traditional house design of Cyprus where Windowss were built above oculus degree to maintain the privateness. Windows on adobe walls were made by puting wooden headers on top of the gaps to back up the bricks above. Terra rossa dirt is present in some countries of Mesaoria field which is a ruddy brown dirt. Colour of adobe bricks might change in different parts of the island. Partition walls inside the edifices were normally built with light timber-framing filled with rubble or plaster. As adobe is a heavy stuff, it was used to construct the external walls merely. Testing adobe samples from the Davies House I scratched a really small sum of adobe from the external wall of the Davies House. It was easy crumbled into little pieces chiefly because of the low strenght of the wall. My chief purpose to prove these samples is to happen out and specify the ingredients of the adobe used in this peculiar edifice. My purpose was besides to happen out the age of the stuff if possible. First phase in the research lab was to look at the samples under a microscope. A little sum from the sample was taken and placed on a faux pas. Soil and straw atoms were clearly seen but it was difficult to place the stuffs clearly. As they were assorted and largely binded with each other, I need to divide the ingredients. The manner of dividing the composite stuff is to blend the coveted sum of sample with H2O and leave it for one twenty-four hours. By this manner, dense and heavy stuffs which are dirt atoms in this instance will drop ; where the light stuffs will drift on the liquid which are the straws that has lower denseness than H2O which makes them float. One-half of the adobe sample is grained by utilizing a cock. A all right grained pulverization was obtained. 5gr of the pulverization was weighted by a sensitive weighting graduated table. It was put inside a glass beaker and 200ml of distilled H2O added to the sample. The mixture was stirred manually for a few proceedingss and so placed on the magnetic scaremonger hot plate. The characteristic of this hot plate is that it has a magnetic field and if a magnet is placed inside the solution, the magnet will do a round spin and stir it. A magnet was put inside the solution and left to stir and heat for about 15 proceedingss. I used a thermometer to mensurate the temperature of the solution and around 42 ° , closed the hot plate. By stirring and warming, I achieved a well-mixed solution. After a few proceedingss, I covered the beaker with a level glass dish and go forth it for a dark. Through research I found out that calcium hydroxide was used to stick on the adobe walls. There are some grounds on the walls of the Davies House but to turn out that, I used hydrochloric acid. Lime is a stuff that contains calcium carbonate. The reaction of hydrochloric acid or any acerb with Ca carbonate will stop up with bring forthing C dioxide which can be seen by bare oculus as air bubbles. In order to turn out that calcium hydroxide was used in Davies House, I put a small sum of adobe pulverization in a trial tubing. Couple of beads of hydrochloric acid is adequate to see the air bubbles. As a consequence, reaction of the acid with the adobe sample is positive which proves that calcium hydroxide was used in this edifice. It besides raises another inquiry that if the type of dirt in Mesaoria contains % 40-60 Ca carbonate, does the reaction with the acid is because of the type of dirt used in adobe bricks? The mixture was left for a dark. Dense and heavy and indissoluble stuffs sink at the underside of the beaker, where light 1s float on the H2O. Water is non clear which can be defined that some of the dirt was dissolved in H2O. A filter paper was placed inside a funnel and an empty glass beaker was placed below. In order to roll up the natation stuffs, I poured the H2O into the funnel easy without upseting the underside. It was difficult to roll up all of the drifting stuff so I used a metal spatula to roll up the staying from the mixture. The H2O was filtered from the funnel, go forthing the straw atoms on the filter paper. Straws were collected from the filter paper and was put together with the 1s that were collected manually inside a porcelain crucible. I left them dry in the room temperature for 15 proceedingss and set them in the oven for 35-40 proceedingss. They were dried wholly and ready to burden. I changed the filter paper and poured the staying H2O into the funnel. Some of the indissoluble stuffs remained at the underside of the beaker so I collected them by the aid of the metal spatula and set indoors another porcelain crucible. Water was filtered after 2 hours from the funnel and I collected the stuffs from the filter paper and put them inside the crucible. Same procedure was made to dry the stuffs. I let them dry in room temperature for a piece and set them in oven for 40-45 proceedingss. Consequences I weighted the obtained stuffs individually by utilizing a reasonable weight graduated table. Insoluble Materials ( dirt, pebbles ) : 4.56gr ( Wa‚? ) Floating Materials ( straws ) : 0.06gr ( Wa‚‚ ) Exact sum of the whole sample was 5.04 gr. The expression below will give the per centums of the stuffs in the sample. Wa‚ Total Weight x 100 = % .. Wa‚‚? Total Weight x 100 = % .. Insoluble Materials ( dirt, pebbles ) : % 90.48 Floating Materials ( straws ) : % 1.19 As the H2O was non clear after go forthing the solution for a dark, it is defined that there are soluble stuffs in the mixture. So if soluble stuffs are Wa‚? ; Wa‚? + Wa‚‚ + Wa‚? = 5.04 gr Wa‚? = 0.42gr Wa‚? = % 8.33 Experiment shows that most of the adobe stuff is dirt. Straws were used to beef up the binding of the bricks. The sum of straws in 5gr is 0.06gr which is really few. As the edifice is old and ignored, straw atoms might hold been disapeared or decayed within the dirt through clip. Original ingredients of the adobe is soil, straws and H2O. In order to turn out that the detached stuffs from my sample is straws, they need to be identified under a microscope. They are most likely straws but there is a possibility that they might be timber. Timber and wooden stuffs are identified under a microscope by looking at the layout of the cells. Wood are chiefly classified in two groups which are soft and difficult forests but the layout of their cells are similar. If horizantal beams of cells are seen under a microscope, it is a wooden construction. Following measure of placing the straw atoms will be to look under a microscope after cutting really thin subdivisions of the pieces. One manner of thinking the age of the wood is to place the fungus formations within the stuff. The dimensions of the fungus might mention to its age. This can be done by utilizing a microscope but merely if the detached atoms are timber/wood but non straw.

Sludge Lab Report free essay sample

For the first physical observation, I tried smelling the mixture. It smelled like permanent marker. Next I tried sticking a spoon in it and stirring the tan solid lightly. It looked like it was an extremely smooth sand. Finally, I tried drinking the liquid. Nah, I’m kidding! To start off, I will describe the liquid. I separated it simply by using the decanting technique. I carefully poured it off of the mixture of solids and into a separate plastic cup. Easy. The physical property of phase was used for separation. It was the only liquid in the mixture. Then I had to identify it. I smelled it and it had a permanent marker smell to it. That led me to believe it was an alcohol. Next, I tried measuring the density using a graduated cylinder and a balance. I measured the amount of alcohol I put in the graduated cylinder (volume) and how many grams it was on the balance (mass). We will write a custom essay sample on Sludge Lab Report or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The volume was 9. 2cm3, the mass was 7. 25g, and the overall density was . 79cm3. That proved my liquid was not water. Finally, I tested the boiling point to determine what type of alcohol it was. I used a ring stand, thermometer, hot plate, test tube, and a beaker full of water. I placed the beaker full of water on the hot plate. I then filled the test tube with my liquid and attached it to the ring stand. Finally, I put the thermometer in the test tube and turned the hot plate on high. The liquid really started boiling around 78 degrees (Celsius), so I concluded that my alcohol was ethyl alcohol. Next we have the blackish/brownish particle layer. To separate it, I used the magnetic retrieval technique. This tests the physical property of magnetism. I simply used a magnet to retrieve the particles and a toothbrush to remove them from the magnet into a separate paper cup. There’s only one substance that is magnetic, but I had to do two more tests. I simply checked solubility in water in alcohol. It wasn’t soluble in either. It was, obviously, iron filings. The third substance I decided to separate from the mixture was the tan sand. After the liquid was removed, the solid wasn’t as silky and it was more like normal sand. I also discovered the â€Å"rocks† were actually clumps of this substance. ANOTHER thing I discovered was white/clear grains. Yes, it was a salt! That means there’s only one way to separate this stuff: dissolve and filter. I poured water onto the rest of the mixture and stirred it up for a solid minute or so. After that, I poured the water into a funnel lined with filter paper which dripped down into another cup. This left me with only the tan sand. First I tried smelling it. It had a REALLY strong smell. Secondly, I recalled it being in the alcohol with a few particles floating around. This got me to believe it was slightly soluble in alcohol. Finally, I tried testing solubility in water. It just floated at the top without any particles floating around in the water, so it wasn’t soluble in water. Due to these factors, I determined it was sulfur. Last, but certainly not least, the white/clear grains. Before I evaporated the water, I took note that it’s soluble in water. To separate it from the water, I evaporated it off. I simply put it on a hot plate, set it on high, and poof. Only grains. By now I identified it as a salt. My next test was alcohol solubility. Turns out, it’s only slightly because the alcohol was very cloudy after the dissolving process. Lastly, I put a sample on a watch glass with some water and left it out over night to check crystal shape. In the end, the crystals were spear shaped, leading me to the conclusion that it was potassium nitrate. All in all, my sludge consisted of ethyl alcohol, iron filings, sulfur, and potassium nitrate. I think my only difficulty was that I discovered the salt fairly late in the process. Overall, I enjoyed this lab because I really felt like I was doing something a real scientist would do. Oh yeah, and I felt a feeling of loss once I had to throw my work away. Sniff.
