A rapid, nondestructive method based on determination of the spatial distribution of ATP, as a potential bioindicator of microbial presence and activity on monuments, artworks, and other samples related to the cultural heritage, was developed [57], After cell lysis, ATP was detected using the bioluminescent firefly luciferin-luciferase system and the method was tested on different kinds of surfaces and matrices. Figure 3 reports the localization of biodeteriogen agents on a marble specimen. Sample geometry is a critical point especially when a quantitative analysis has to be performed however, the developed method showed that with opti-... [Pg.484]

Zukoski and Marble [70, 71] held that the wake of a flame holder establishes a critical ignition time. Their experiments, as indicated earlier, established that the length of the recirculating zone was determined by the characteristic dimension of the stabilizer. At the blowoff condition, they assumed that the free-stream combustible mixture flowing past the stabilizer had a contact time equal to the ignition time associated with the mixture that is, rw = ri( where rw is the flow contact time with the wake and r, is the ignition time. Since the flow contact time is given by... [Pg.246]

For example, consider a jar of marbles and the probability that you ll pick a red one. Or you look at the seats in an airplane and determine the probability of your getting a particular seat. Or how about the number of boys in a family How does a number of boys become a probability problem (Well, boys can be a problem — I don t know about the probability part.)... [Pg.102]

A particular product (commodity) (material) must become the subject of money, which exists as the attribute of every exchange value. The subject in which this symbol is represented is not a matter of indifference, since the demands placed on the representing subject are contained in the conditions - conceptual determinations, characteristic relations - of that which is to be represented. The study of the precious metals as subjects of the money relations, as incarnations of the latter, is therefore by no means a matter lying outside the realm of political economy, as Proudhon believes, any more than the physical composition of paint, and of marble, lie outside the realm of painting and sculpture.27... [Pg.85]

Unless you throw marbles really hard or have a wimpy roll of masking tape Um betting the roll of masking tape (or whatever object you used) didn t move when you rolled marbles at it. And I m betting you reached the conclusion that if the tape was invisible and you rolled enough marbles you would be able to determine the size and location of the tape fairly accurately. [Pg.45]

Firing a marble at a marble of course is a different story. The "invisible" marble moves away when you hit it with another marble. So while you might have known where the invisible marble was when you hit it, you do not know where it is (after the collision) or how fast it s moving. Therefore, you can t accurately determine a marble s location by hitting it with another marble. This leads us to a conclusion ... [Pg.45]

Once the tray eflBciency is known, the number of marble beds needed to obtain the required SO2 removal can be determined from the operating and the equilibrium lines. The equilibrium line is plotted using a computer program and the total alkalinity of the liquid available in the scrubber which is a function of the additive dissolution rate for slurry systems. For a specific L/G, the equilibrium line shown in Figure 4 moves to the left or right depending on the alkalinity of liquid available in the scrubber and, hence, aflFects the SO2 removal eflBciency. The SO2 removal eflBciency is defined as ... [Pg.143]

The natural history of Type-II diabetes mellitus is characterized by a progression of B-cell dysfunction. Many patients are initially well controlled by diet but, as the years go by, they need oral hypoglycaemic agents and eventually insulin for satisfactory glycaemic control. Some 17% of all Type-II diabetics are treated with insulin, and 5% of Type-II diabetics are switched to insulin each year (Marble and Camerini-Davalos, 1961). The point at which a patient should be put on a insulin regimen, however, is not always easy to assess and may be determined by life expectancy, morbidity and compliance of the patient. [Pg.22]

Carbon and nitrogen isotopes in archaeology are used primarily in the study of past diet, but there are also important applications that concern past environments and human activity. Carbon and oxygen isotopes have been used in proveniencing to determine the source of marble and other forms of carbonate rocks. Carbon isotopes have been used as survey tool to locate the boundaries of ancient soils and determine the extent of certain types of vegetation. The discussion below focuses on human bone and questions about past diets, the primary application of these two isotopic systems. These principles are also involved in the study of other questions. [Pg.92]

Approximately one liter of rainfall-runoff solution was collected from each of three experimental racks following rainfall events. Limestone and marble reference rocks were in two of the racks a third rack without a rock was used as a control (hereinafter referred to as a blank sample). Runoff volume, specific conductance, and pH measurements were determined at the exposure site as soon as possible after collection, typically within a few hours. Samples then were filtered through a 0.45-micrometer pore size membrane filter, placed in a clean polyethlyene bottle, and sent to the U.S. Geological Survey laboratory in Denver, Colorado, for chemical analysis. Sample preparation, analytical procedures, and laboratory quality-control protocols are described by Skougstad et al. (6). [Pg.230]
