The hornblende andesite is a major rock forming mineral that is found in different types of igneous and metamorphic environment. There are two varieties of the hornblende andesite rocks. One that is gray and slightly purplish in color, friable, fine-grained, and somewhat porous. The other type is dark gray in color, and much more compact and firm in texture. This paper examines the physical and chemical characteristics of the hornblende andesite. An understanding established for this type of rock is very crucial in determining where it can be used. A field research was done where ...

... 05 Production and Cost     Essay Questions   Always Round Tire has a production function of Q = 300 L.75 K.5. In the short run, if L = 250 and K = 25, what happens to the output of tires if L jumps to 300 and then 350. What law does this illustrate?  When L=250 and K=25 then Q=94307. When L increases to 300, Q increases to 108,127. When L increases to 350, Q increases to 121,379. This shows the effects of diminishing marginal returns to labor as a factor of production. Always Round Tire has a production function of Q = 300 L.75 K.5 . If Always Round Tire doubles the size of its production facility – increasing L from 250 to 500 and K from 25 to 50 – what happens to the cost of production, even...

... stress and strain Case Study November 02, Memos Prof. November 02 a) the graph of stress (Pa x1010) against strain From the graph stress of a material decreases gradually with increase in strain this means the material becomes non linear as stress is increased. This may be associated with rearrangement of molecules with the structure of aluminum. As strain is increased atoms move to new positions to create new equilibrium in the material. This is because of their nature in mobility and dislocation. The graph is linear to a certain point but it deviates when the limit is reached. A fracture may be experienced if a strain continues beyond the proportionate limit. At zero the graph is starting to form...

... by: here. of Department of Chemistry. Introduction of the Research Problem. Synthesized polymers are no doubt some of the most used products around the globe today and their use can only increase. Application of polymers is evidence in their daily utilization in packaging, electrical appliances and biomedical devices. Even with their great usage they pose a significant challenge in the form of adverse environmental effects resulting from their improper disposal. This necessitates the search for newer polymer types that are environment friendly. This can be attained through development of chemical protocols requiring less energy, procedures with lower dependency on fossil fuel, and that yield less ...

... Brand Minimalism In this magazine, Spector and Kitnick assert that people who visited Chicago’s Renaissance Society in 1980 winter came across a concise exhibition with an incendiary thesis. This thesis was “Objects and Logotypes: Relationships Between Minimalist Art and Corporate Design.” It was seen to be a polemical connection of two strands of American postwar culture that could not be opposed at first (Spector and Kitnick, 2014). The magazine has a picture that shows corporate logotypes hanging on the walls, the ionic forms needed to be projected with a single combination of images and texts. On the other hand, the picture in this magazine has coherent identities for sprawling multinationals su...

... Assignment by SECTION A Operation of the brake disc in the braking system Disc brakes can either be used on all the four wheels of the vehicle or only on the front wheels combined with drum brakes on the rear wheels. The brake disc operates in a way such that when the brake pedal is pressed by the driver, a force is transferred by the push rod through the brake booster on to the hydraulic master cylinder. This hydraulic master cylinder is responsible for conversion of this force in to a hydraulic pressure which is transmitted via the brake fluid, the connecting pipes and hoses to the piston at each brake caliper. Due to this pressure exerted on the pistons, the pistons in turn exert friction on the ...
