Miami Circle Article Example | Topics and Well Written Essays - 750 words

Miami Circle - Article Example The excavation, conducted under Bob Carr revealed a patterned group of holes in various sizes cut into the oolitic limestone. This covered a circular shaped area of 38 feet in diameter. And the excavated earth contained various artefacts like shell tools and stone axe-heads. Other crucial discoveries included human teeth and charcoal from fires. According to the diary report of Ryan J Wheeler, one of the archeologists who participatred in the escavation, they also found '.some concrete, modern glass, and other construction fill, lower portions produced nineteenth century materials, including the fragmentary neck of a blown green glass bottle and a wire-wound glass button, probably from a ladies' blouse or jacket. (Wheeler). A controversy regarding the preservation of the site ensued, especially after the suggestion by Baumann to relocate the circle to another location for which he offered to pay the expenses so that he could pursue the construction of the condominium. But there was a general resentment among the general public which included archaelogists, native americans, new agers and school children. And the State the State of Florida Preservation 2000 land acquisition program had to purchase the disputed site from Bachmann for $26.7 million. The radiocarbon dating, conduct... However, the argument that the holes belonged to the modern age was further disputed by Tom Scott and Harvey Means, Florida Geological Survey, who brought to light the fact that there was a buildup of a calcite duracrust on the edge of the cut face, which cannot happen in the case of modern objects. The artefacts that were found are supposed to belong the Tequesta native group which existed prior to the European settlement of the area. But to come to such a conclusion, other possibilities were to be discounted. There is no proof that native North Americans built such permanent structures so long ago. And the hypothesis that the site could have belonged to the Olemec or Mayan civilizations was more or less ruled out as there was no evidence of any artefact belonging to Cetral American origin on the site. According to Bob Carr, "Mayan architecture is always rectilinear, except for the observatory in the Yucatan, so really nothing about this fits a Mayan connection." He thinks that the references to Mayan civilization in this context are "just an exotic way to explain it." (Nimnicht). There exists an argument that the holes were postholes of some structure, some sort a foundation for a building. Another hint is that it could have been a burial site, but the excavators could find o nly a five-foot long shark skeleton, a dolphin skull and a complete carapace of a sea turtle. Apart from the four human teeth found on the site, nothing confirmed to the idea that it could have a common burial ground.The controversy regarding the decision of the Sate to spend a phenomenal amount on the project reached its height with the hunch by the University of Florida archaeologist Jerald T Milanich that the Circle

Chemistry assignment - Essay Example Thus we must multiply 3 to get the integers 3 and 4, for Fe and O subscripts respectively. This is the simplest, or empirical, formula because the subscripts are the smallest integers that express ratios of atoms present in the compound. Certain elements appear to violate the rules in electron configuration. The electron configuration of chromium is rather than , as one might have expected. Similarly, the configuration of copper is instead of . This anomalous behavior is largely a consequence of the closeness of the 3d and 4s orbital energies. It frequently occurs when there are enough electrons to lead to precisely half-filled sets of degenerate orbitals (as in chromium) or to completely filled d subshell (as in copper). Increasing the distance from the nucleus decreases the attraction between the electrons and the nucleus. As this attraction decreases, it becomes easier to remove the electron and, thus, lower ionization energy. Element A has the largest atomic number (greatest distance between outer electron and nucleus) because it has the least ionization energy. The ionization energies for an element increase in magnitude as successive electrons are removed. But when the next electron removed is an inner-shell electron, there is a sharp increase in ionization energy. The figure shown below tells us which group elements A-E should be placed. 19. 27.823g of Na2CO3.xH2O crystals were dissolved in water and made up to 1000 cm3 of solution. 25 cm3 of this solution required 48.8 cm3 of 0.1 mol dm-3 HCI for complete neutralisation. Find the value of x in Na2CO3.xH2O using the following steps: 20. 4.00g of lawn sand (a mixture of sand and ammonium sulphate) was weighed into a conical flask, and 25 cm3 of 2.0 mol dm-3 sodium hydroxide solution was pipetted into the same flask. The conical flask was boiled for 20 minutes, after which time all the ammonia had been driven off,

EYEWITNESS TO HISTORY Assignment Example | Topics and Well Written Essays - 250 words

EYEWITNESS TO HISTORY - Assignment Example What impression do you think Diaz had of Aztec civilization? How does he make his feelings clear? Diaz and company were all astonished having found a great size of Aztec population who had been fond of merchandising goods of various kinds. At a point, he appeared to gain a remarkable impression of the market’s orderliness which maintained goods in appropriate arrangements. Despite his testimonial of the Aztec people’s culture of giving significance to excrements, Diaz attempted to clear his little amount of shame for New Spain by stating how he sensed similarities and connection with his own homeland district where market stalls and fairs with this scenario were a common sight as well. What can we learn regarding Aztec culture, economics, and science from this? Based on such findings, one may readily claim that Aztec culture was rich in its own way since the people of Aztec civilization managed to identify advantages among diverse resources. This way, the economy may be thought to acquire flexibility in which everyone had a job to do that matched specific individual potentials.

Composites Essay Example | Topics and Well Written Essays - 750 words

Composites - Essay Example l made by combining two or more distinct materials in order to fabricate a new product bearing desirable combination of properties that a single materials cannot achieve (Noort & Barbour, 2013). These materials range from polymer, metallic to ceramic elements (Naseem, 2010). Dental composites are wear resistant including composite resins, glass monomer cement, compomers and giomers For this case, I will design a composite that meant to replace amalgam as filler in dentistry. The composite must have a pH change as well as the ability to form a carboxylate salt. The material also has to contain fluoro-aluminosilicate glass, water as well as a polymeric acid (Brantley, & Eliades, 2011). In addition, the material ought to have improved physical conditions compared to conventional glass ionomoer. Such improvements aid reduction in water sensitivity, less fluoride release, rechargeable fluoride besides increase in thermal expansion (Naseem, 2010). Most importantly, the material has to be light cured to achieve good bonding to dentine, which depends on surface conditioning (Brantley & Eliades, 2011). The composite used should be anisotropic since forces from different directions act on them.The forces acting on the other direction enhance materials properties in one direction (Brantley, & Eliades, 2011). Properties of strengths and stiffness depend on the direction of force applied. Transverse direction will be necessary for the composite because elastic constants are similar (Brantley, &Eliades, 2011). Physical properties of the material needed for matrix include low solubility, high compressive strengths, as well as low flexural and sheer strengths. In addition, the material must have a thermal coefficient similar to dentin besides fluoride release and fluoride recharge. Glass monomer cement binds tooth and has diverse dimensions such as slight shrinking and expansion when setting (Naseem, 2010). It is also brittle and lacks translucency characterized by a rough

One of the project manager lefted the company to join a software production team in canada. The problem was the failure in project delivery to customers in the appointee time. Each project was delivered to the customers with seven to twenty days delay. This caused the studio to cancel some of the newly received projects in order to accomplish the old orders in shortest possible time and this caused the company to loose 7 orders worth of $47500 in June 2006. Nothing in the studio's total structure was changed exept for the project management because the company had lost %33 of it's management power. This seemed to be the cause of the failure in delivering the orders in time but other factors like the productivity of the personnel and their expertise in the field they were working could be questioned too. Not all the orders have been the same, for example, an employee might have been assigned to an order which has not been in the scope of his knowlege no matter if he/she has taken the order because of a good income or it has been the manager's decision. In next section, we will have an overview to some of the most appropriate management science methods that seems they may help us resolve the issue in the shortest possible time. We will then select the most appropriate method to resolve the issue with. 2. Reviewing some of the most appropriate management science methods for analysing the situation "Management science, or MS, is the discipline of using mathematics, and other analytical methods, to help make better business decisions. While often considered synonymous with Operations research (OR), MS is differentiated by being generally thought to have a more practical, rather than academic, bent.

How to Recruit and Retain Volunteers Essay Example | Topics and Well Written Essays - 500 words

How to Recruit and Retain Volunteers - Essay Example Others performed the duty due to court-mandated work as part of the sentence from a judge. Irrelevant of the motive non-profit organizations have to promote themselves adequately to attract volunteers and financial donations. I selected an online-articled entitled How to Recruit and Retain Volunteers for further analysis of the topic. The article stated that three ways to recruit employees is by using personal contacts, going where the people are, and by getting the word out (Genv, Youth Venture, 2007). I totally agree with the strategies chosen in the article. Word of mouth advertising is priceless and the costs of implementation are minimal or nonexistent depending on the situation. Non-profit organizations have to be proactive in their marketing and recruiting initiatives. It is wise idea to formulate seminars to be present at different locations such as churches, universities, and public parks. Personal contacts can be very valuable. The manager of the non-profit organization has to use his or her network of family, friends, associates, and colleagues to directly recruit these individuals to donate some of their time. The decision maker or manager of the non-profit organization must possess excellent communication and leadership skills. The organization must also recruit volunteers from the corporate sector. Many private organizations are willing to provide support in terms of capital or manpower when non-profit organization ask for the help and are able to negotiate a deal. The second important aspect of managing volunteers is being able to retain the personnel. A list of strategies and tactics that can be used to manage volunteers to keep them motivated and happy is listed below: People that are welcoming and nice create an environment that is pleasant for the volunteer which helps keep the volunteers interested. By making the work fun the volunteers enjoy their time which helps to keep them motivated. It is important
