A Gaseous Substance

In conclusion what makes Oobleck act like both a liquid and a solid? In your mind think that you can see the individual molecules of corn flour and water then think about how they might act when being pushed and pulled. The corn flour and water mixture will act like a solid and a liquid this type of mixture is an example of suspension. The particles stay undissolved in a liquid and corn flour molecules are dispersed into the water. If the cornstarch mixture is pinched, it causes the molecules to go closer together. The effect of the force traps the water between the flour molecules to form a solid shape. When you let go the pressure of your fingers the corn flour will be able to flow like liquid. Viscosity is the resistance for a liquid to

A polyurethane coating is a high gloss finish with exceptional weathering performance characteristics and superior resistance to corrosion and chemicals. The Navy Industrial Hygienist does an annual assessment for the entire command and does the paint operations quarterly. The Hygienist has been conducting a workplace assessment survey of all touch-up painting operations on aircraft and equipment for the past 12 years and the survey records are located in a file cabinet in Shawn Hurdle office. A team of 4 will be here beginning July 7th for a week monitoring our processes and operations. They take an assessment of areas with high potential risk for injuries, occupational illness or damage to Navy

The method more often than not includes kneading or pushing the inward side of a harmed region once again into its unique structure with the utilization of specially designed metal bars and picks. An expert will frequently utilize different assistants to expand the accuracy and nature of his work, for example, distinctive lights and

The artist first coats the metal plate in an acid-resistant substance known as ground and is drawn on. The artist then uses a sharp tool or etching needle down to the plate. “Hard grounds are employed for finely detailed linear work. Soft ground can also be used, and virtually any tool can be used to expose the plate and resembles crayon and pencil drawings” (Sayre, 2012). Whichever ground is used by the artist is then placed in an acid bath. “The acid eats, or etches, into the plate where the lines have been drawn; the longer the exposed plate is left in the bath, and the stronger the solution, the greater the width and depth of the etched line” (Sayre, 2012). An artist can also create a way in stopping out a section by using varnishes or ground over the etched surface. Once the plate is finished being exposed to acid, it is inked and printed.

Qualification: To flatten and repair wall, ceiling, or surfaces. High adhesion, easy application and durable against weathering. Not peeling or chalking. Can show material surface after coating (no need to paint). No mercury and lead added.

One of the duties of a Gunsmith is to provide protection for firearms. This can be done by; cleaning, fixing, restoration, beautifying or even Parkerizing. According to Oxforddictionaries.com (2017), Parkerizing, is a process for rustproofing iron or steel by brief immersion in a hot acidic solution of a metal phosphate. In this week’s reflection video, I learned about a Gunsmithing shortcut to produce Parkerizing on small weapons parts. Parkerizing, is a process of using manganese or zinc phosphate to coat steel weapon parts.

Marshall Berman’s take on modernity is presented in his book All That Is Solid Melts into Air whereby he focuses on its issues and the cultural attitudes and philosophies towards the modern condition. In doing so he shares his experiences of modernity post WWII in New York in the height of an economic boom and then more specifically of his childhood neighbourhood, the Bronx. In addition to expanded austerity, industrial and architectural development, the end of WWII proved to be a key period in world history and by extension the history of art. A talented group of artists emerged in result that had been influenced by an influx of established European artist who had fled to New York to escape fascist regimes in their homelands. More importantly these artists produced art that was at the heart of maelstrom Berman describes in regards to his experience of modernity. I aim to highlight the correlation between Berman’s experience of modernity and the emergence of a new American modernism. Modernity throughout this period was broken into two different compartments, hermetically sealed off from one another: "modernisation" in economics and politics, "modernism" in art, culture and sensibility. It’s through the lens of this dualism in which we recognise that both Berman and these artists try to make sense of the world around them by making their individual expressions that would re-conceptualise what it is to be modern in the twentieth century.

     Also according to our book in Art History, “Etching process, a metal plate is coated on both sides with an acid-resistant varnish... then the artist draws through the varnish with a sharp needle to expose the metal” (Stokstad pg. 772). In this process the artist can easily control the amount

The 3D manufacturing through additive rapid prototyping comprises of a layering process. Commercially available prototyping machines include: steriolithography apparatus (SLA), selective laser sintering (SLS), laminated object manufacturing (LOM), multi-jet modeling (MJM) and fused deposition modeling (FDM) (11). Safety for intra-oral use of most of the currently available rapid prototyping materials remains a concern. In 2012, Inokoshi and colleagues utilized an ultra-violet-cured acrylic based resin material for the fabrication of trial dentures (FullCure720, Objet Geometries, Rehovot, Israel); which was approved for medical use with regards to cytotoxicity and sensitization standards by the United States Pharmacopeia (USP) Class VI. The gingival tissues were created by painting the prostheses with pink composite resins

than learning better when I am moving around and doing activities. Two good ideas to use while in a classroom are using flashcards and taking brakes. Using flashcards are a good idea because they help me learn better by doing something. Also, taking breaks will help me not be so overwhelmed. According to the quiz I am tactile and I work better using my hands. I agree completely because that is how I learn best and how I will continue to learn and study so I do better.

Some marine species achieve great dispersal distances and range expansions with the assistance of floating propagules such as rafts, which provide habitat for the duration of their time afloat (Edgar 1987; Jokiel 1990; Helmuth et al. 1994; Thiel et al. 2005). The distance that propagules disperse may control the demographics of marine populations, in addition to governing the rates of colonization, range expansion, and genetic exchange(Kinlan et al. 2003; Donald et al. 2005). Biologists also speculate that passive rafting plays a key role in colonising isolated environments such as islands (Kinlan et al. 2003; Fraser et al. 2011), with many ‘non-dispersive’ coastal species incapable of reaching these locations independently (Jokiel 1990; Kinlan

Engraving evolved from only carving in glass to the action of acid cutting into metal or glass to texture a design. According to the Association Acid Etched, glass has been etched with the dangerous hydrofluoric acid. The removal of the silica from the surface of the glass leaves the glass with a roughened and frosted appearance (Acid Etching). The process of etching is roughing a piece of glass in particular surfaces to produce a design. This etching is known as abrasive or sandblast etching; the most used method of glass etching. Sandblasting, multi-level etching and carving are the most common 'used techniques.

Ethylene gas is one of the by-products of respiration, and occurs naturally as produce ripens. It can have both positive and negative impacts upon your program. Ethylene is a natural gas made by some fruits and vegetables. Ethylene causes certain fruits and vegetables to ripen faster, which can lead to over-ripening and spoilage. For this reason, you want to be careful to keep ethylene-producing items away from ethylene-sensitive product and that your storage and display areas have good ventilation. Spoiled produce makes even more ethylene (one bad apple spoils a bunch)!

Anodizing is an industrial process applied to metals to make them harder and more resistant to corrosion. Metals gradually degrade when in contact with moisture and when exposed to air, a process known as oxidation. They form an oxide layer which is softer than the metal and can easily be peeled away either mechanically, like when it rusts, or chemically, such as when it combines with other substances such as strong acids and bases.
