4. Analyzing lithics can be quite difficult for someone that is relatively new to the discipline. The same thing goes when analyzing use-ware. It is a very difficult skill to master. Comparing the pseudo-tools and the trampled flakes I was able to see some similarities between the two sets. They all had a high presence of scalar fracture scars. The trampled set of flakes had a hire number of half –moon fracture scars. The hinged/step fracture scars where around the same throughout all the flakes. This could be because there was constant movement and lite pressure applied to the edge of the tools would produce more scalar fracture scars, while the rough uneven high pressure from the force of the trampling would create half-moon fracture
Each tool and weapon was made from certain items, and they each are used in a different way.
Corresponding to the previous experiment, this week’s experiment measures the participants’ ability to conduct basic, fundamental laboratory procedures. These procedures revolve around scientific measurements of volume, mass, and density. Unlike last week’s activity, this week’s experiment had a few modifications. In addition to distilled water, saltwater and an unknown substance were added. There was a total of five substances to choose from; Hexane, Methanol, Ethyl acetate, Ethylene glycol, and Dichloromethane. Part C, the unknown liquid number was four, which the average density was 0.789 gmL-1, and from looking at the chart the unknown identity was methanol. Part A, the temperature of the water was 20 oC, which was in front of the class,
If we want to analyse the political factors which impact upon the company we need to make a general view of the situation in the country. What are its law and requirements?
Curled Metal Inc. (CMI) examines a new potential product: using wounded, flattened curled metal as a cushion pad for piles driving hammers.
[pic]we also noticed the different types of tools used to hunt from the lowest level to the most current level and retouched flakes prevailed during all periods we have determined by our excavations. This was a favorite weapon to hunt and perhaps used to hunt larger preys found in the area. The use of end scraper also prevailed for many years and it was probably used to tear up the skin to cover themselves in the cold winter time. Other tools were also found, but a significant lower number.
The Rolla-bottle is newly modernised type of reusable water bottle founded by Katy and Elizabeth Reed.
Oldowan tools are a very rudimentary form of a stone tool in which it is formed simply by smashing two rocks together until the rock splinters. If the splinter becomes sharp, it can be used as a tool for cutting. These tools were likely used for scavenging and cutting meat from animals that were previously killed by another predator. An individual would either use the oldowan tool to scrape and cut meat from a bone, or smash the cranial and long bones to obtain brain matter or bone marrow. The bones of local fauna show a parallel scrape marks that indicate tool use. Under a microscope, one can see the patterns created by these tools. If the marks were in a “V” shape, it would indicate a scrape pattern consistent with the bite of a carnivore. Because of the parallel scrape marks; we can deduce that tools made the
Some of the companies have best policies to attract the customers even in economic crisis. But are they really success in doing so. Cutting the prices may be the solutions for a middle class customer to buy goods.
First, the article states that one theory is that they were used in hunting or fighting. However, the professor opposes this point by saying that the common neolithic weapons are generally shown the sign of ware, so if the carved stone balls were used for hunting, they should be cracked, but their surface was preserved without any damages, so they unlikely were used for hunting or fighting purposes.
The photographs should also show where the toolmark was located, how the object on which it was found was arranged, and how big it was. Once everything has been photographed a cast can be made of or the area on which on toolmark was found can be removed. When making a cast there needs to be a mixture to get the fine details of the markings so it can be analyzed for a microscopic comparison. When the tool and tool mark are being compared the examiner will look for unique characteristics that they both contain or a serial number is located to see if it was imprinted onto a surface (WILEnet).
The purpose of this experiment was to observe the different kind of crystal package arrangements that each material experienced after an impact load. For this reason, a varying range of temperatures were used during the experiment. As a result, comparing the effects that temperatures had on the types of fractures each material experimented.

First, The reading states that these stone balls may be used for hunting or fighting. The author mentions that there are some holes or grooves in them. The author believes these holes and grooves may be used for holding a cord during hunting or fighting. The lecturer, however, opposed with this theory. She says that surface of these stone balls shows no or little wear or damage whereas, we expect many of these balls should be cracked or damaged.
By a method called direct percussion, a core stone called a biface was hit with a hammer stone to produce flakes. The biface was made into choppers called the Oldawan pebble
