Hills, Rust

By then I was halfway up Avery Hill, where the ack-ack guns I d never heard firing had long gone but the concrete platforms and bunkers remained, broken now, with twisted bones of rusting steel, and shadows and hollows, and stairs that led down to nowhere. 

Rust Hills, a well-known editor, characterizes the short story as a story that tells of something that happened to someone. Second, the successful contemporary short story will demonstrate a more harmonious relationship of all its aspects than will any other literary art form excepting perhaps lyric poetry."1 He also suggests that the story is dynamic, that the character is moved in the course of experience of the story, and that there are few secondary characters and no subplot. Often the story will unfold around a choice that presents itself to the character, who never returns to his or her former state closure is attained by virtue of making or avoiding that choice.2 Rust Hills s observations about the short story could be as readily applied to the short film.

Some reactions go virtually to what we call completion—the conversion of such a large quantity of the reactants to products that what is unconverted is not noticeable and is unimportant. The combination of hydrogen and oxygen to form water is a reaction of this kind. Once a spark has gotten the first few molecules over the activation energy hill, the reaction continues rapidly and explosively until one or both reactants are used up. A slow reaction can also go to completion. As time passes, an iron nail exposed to the atmosphere continues to rust away gradually, until only the rust remains. 

The stony meteorites collected during the 1977/78 field season on the icefields adjacent to the Allan Hills included seven specimens that contain deposits of white efflorescences on their surfaces and in cracks. Marvin (1980) reported that these deposits were composed of the hydrated carbonates and snlfates of magnesium and calcium listed in Table 18.6. In spite of the presence of these deposits, only two of the seven specimens have rust stains. The absence of heavy rust stains is difficult to reconcile with the prevalence of Mg-salts... 

The first evidence for the conversion of silicate minerals of stony meteorites in Antarctica was reported by Gooding (1986a) who detected the presence of clay mineraloids, gypsum, K-Fe sulfates (jarosite ), and rust on the surfaces and in cracks of achondrites and chondrites from Elephant Moraine (EET) and the Allan Hills. These weathering products had formed primarily from glass and plagioclase in the fusion crust and in cracks in the interiors of the meteorite specimens. 

One of the most important questions is whether different resistant wheat isolines only react quantitatively or if there are qualitatively distinct mechanisms of resistance which lead to specific types of answers. To elucidate this, we measured net photosynthesis, chlorophyll content, and DCMU sensitive Hill activity (H O -> ferricyanide) of a susceptible, a moderately resistant, and a highly resistant near isogenic line of the wheat cultivar Prelude following stem rust inoculation. 

Highly Resistant Isoline In the first days post inoculation, net photosynthesis of the infected leaves increases (Fig. 7). Depending on infection density there may later on be a slight decrease below the controls (data not shown). The chlorophyll content remains nearly unaffected by infection (Fig. 8). Neither Hill activity from H O -> ferri-cyanide (PSII + PSI) nor PSII activity are influenced by the rust infection (Fig. 9).

Why does a chemical reaction go naturally in a particular direction To answer this question, we need to look at spontaneous processes. A spontaneous process is a physical or chemical change that occurs by itself. It requires no continuing outside agency to make it happen. A rock at the top of a hill rolls down (Figure 19.4, top). Heat flows from a hot object to a cold one. An iron object rusts in moist air (Figure 19.5). These...
