Corn smuts are widely distributed throughout the world. The incidence of corn smuts in the Pacific Northwest (PNW) varies by location and is usually low. Nonetheless, these diseases occasionally cause significant economic losses when susceptible cultivars are grown under conditions favorable for disease development. Smut diseases of corn are, in general, more destructive to sweet corn than to field corn.

Course description: Cinematography is a craft; a craft that is in a constant state of change. Change is driven by new products, new technology, but more than all of those the pressure on those practicing the craft to push out the “envelope”. Like all crafts there are facts and formulas; the “science” to learn. And there is the “art”, which is harder and takes longer to learn. The course covers the fundamentals of lighting, exposure, use of film and motion picture cameras, general use of equipment, safety procedures, and methodology for working on location and in the studio; the aesthetics, techniques, and technology of cinematography and how it is currently practiced in the television and motion picture industry. Class meetings will consist of lectures, group discussions, in-class demonstrations, and viewing of contemporary films.

An attempt is made to explain the ability of Superman to jump high buildings and deflect bullets. It is hypothesised that these powers come from a superhuman density of muscle and this theory is tested and found lacking. Introduction In Superman's first comic book appearance it was said that he could “easily hurdle a twenty storey building...and that nothing less than a burning shell could penetrate his skin”[1]. Superman's humanoid appearance suggests a (albeit super-‐) humanoid physiology. This paper will investigate muscle density as the source of both his superhuman strength and his ability of bullet deflection. Discussion For Superman to jump a 20 storey building – approximately 100m in height – he must leave the ground at a vertical speed of 44ms. This assumes that acceleration remains constant, that the vertical speed at the peak of the jump is 0ms, that there is no effect from air resistance and that (at this point in his mythology) Superman is not immune to gravity. In order to reach this speed, from a stationary start, over the distance Superman travels between his initial crouch and take off (taken to be 0.5m), an acceleration of approximately 2000ms is needed. The force required for this acceleration is, F = 2000m (1) where m is the mass of the object being accelerated. This force is assumed to have come solely from Superman's leg muscles. Humans muscles are composed of many microfibres, each one capable of producing approximately 0.3μN of force[2]. In practice many factors may affect the strength of a muscle including its shape and the proportions of different fibres present, but, for the purposes of this paper, the muscle strength is proportional to the number of fibres. As, visibly, Superman's muscles are no larger than a similarly sized human's, if his physiology is similar to humans then he must have a greater muscle density. In humans, muscle density is averaged at 1.06gcm[3]. In a similar way to the calculation
