چکیده

Malleable cast iron is one of the irons that has excellent forging properties. result heat treatment white iron, so cementite decomposed to form graphite in rosettes. often used for tooling and on railway components. Testing determine fatigue limit malleable very important it can find out maximum load receive. Fatigue testing was carried with variations loading angles 1o, 2o, 3o, 4o 5o. From tests out, below a voltage 100.4 MPa. Metallographic also microstructure iron. The formed specimen rosette there ferrite phase, tested matrix ferritic Fault surfaces specimens were observed through visual observation scanning electron microscopy (SEM). Through observations surface fault, beachmark are seen, given angle 1o wider area compared other angles. This because smaller angle, crack propagation will be wider. SEM indicate fracture occurred transgranular fracture.

Proof. There are three cases: (1) A and B are in the same column. Then, since in each column we picked the shortest student, A is shorter than B. (2) A and B are in the same row. Then, since in each row we picked the tallest student, B is taller than A. (3) A and B are neither in the same row, nor in the same column. Let C be a student who is in the same row as A and in the same column as B. Th...

An objection to the memetic approach to culture Memetics is one possible evolutionary approach to the study of culture. Boyd and Richerson's models (1985, Boyd this volume), or my epidemiology of representations (1985, 1996), are among other possible evolutionary approaches inspired in various ways by Darwin. The memetic approach is based on the claim that culture is made of memes. If one takes...

Many scientists have until recently considered consciousness to be unsuitable for scientific research. As Damasio remarks, ‘studying consciousness was simply not the thing to do before you made tenure, and even after you did it was looked upon with suspicion’ (Damasio, 1999, p. 7). Prompted by technological developments as well as conceptual changes, this attitude has changed within the last de...
