Experiment-II

The SM-1 and 2 control rods are of the absorber-fuel element follower type. The absorber is a hollow stainless steel-boron carbide box while the control rod fuel element is composed of 16 parallel plates similar in composition to the stationary elements. These two components are contained in a stainless steel basket which is driven into the core for control purposes. 

Both the SM-1 and SM-2 core arrays consist of 38stationary fuel elements plus 7control rod assemblies arranged in a 7x7 fuel element lattice with the four corner elements removed. With the thicker SM-2 fuel plates and a consequent increase in the metal tO water ratio, and the higher SM-2 fuel loading and thermal rating a flexible critical experiment was deemed essential to sound design and safe operation. 

Parametric studies were performed in which core excess reactivity was related to uranium-235 and boron-10 loading and metal to water ratio. The merits of two different control arrays were studied and critical stuck rod configurations established for start-up and mid-life cores. Power distribution in the core was measured. A presentation of typical SM-2 start-up core data follows

The 13C NMR spectrum for Experiment II appeared to consist of two sets of resonances that corresponded to Pyroglu. We speculate this is due to a Pyroglu-prolinol salt adduct.

Experiment II. Volatile compounds from leaves and bulbs Volatiles (terpenoids, ethylene and other compounds) can be released from the leaves and other plant parts and consequently can affect the germination of seeds, growth and development of neighbouring plants in ecosystems. 

Gas analysis shows that, whereas in Experiments II and III CO2 is clearly observable (from the water gas shift), no CO2 can be detected in Experiments VI-IX. In the latter experiments only a trace of CH4 (corresponding to less than 2 % based on converted methyl acetate) is found.

Experiment II. Horizontal and Vertical Polarizers. (1) Let P be a horizontal polarizer the amplitude of the transmitted wave is E and the irradiance 1 recorded by the detector is E E. (2) Let P be a vertical polarizer the amplitude of the transmitted wave is E and the irradiance I recorded by the detector is E E. The difference between these two measured irradiances is... 

Studies of canavanine interaction with the tobacco hornworm and J-. miTior also revealed the marked ability of canavanine.to inhibit whole organism incorporation of [ Hjthymidine and uridine into trichloroacetic acid-precipitated materials. When canavanine is provided simultaneously with the appropriate radio-labeled precursor, ample evidence for curtailed nucleic acid metabolism emerges but protein synthesis is unaffected (Table I, exp. I). In experiment II, canavanine is allowed to assimilate... 

Experiment II. The sample was irradiated for 6 minutes in the absence of significant stress (< 10 p.s.i.g.), at which time the stress (2300 p.s.i.g.) was applied by remote control without changing the irradiation conditions. Deflection measurements were continued for another 5.5 minutes, at which time the beam was turned off (Figure 6, II). 

The results of Experiment II show that when the sample is first irradiated under no stress and then the stress is applied, the creep rate has an initially high value but decays to a steady rate after a few minutes. In contrast to this behavior, the same steady creep rate is achieved in a much shorter time—e.g., less than 30 seconds in Experiment III for the same stress and radiation conditions in this latter case, the beam... 

In experiments (i) and (iv), no oxidation was observed after 50 h, in toluene / oxygen at 80 °C implying that a perruthenate derived species was responsible for the catalysis and not Ru02. In experiments (i) and (iii), approximately 10% and 70% oxidation respectively, to the aldehyde was observed after 3 days under the same conditions and complete leaching of potassium perruthenate was observed in both cases. The used solid material from experiments (ii) and (iii) showed no catalytic oxidative activity when reused.. 

Experiment II. In a second experiment, a series of test tubes were set up, each containing a different amount of buffered substrate at pH 7 but each in a volume of exactly 4.00 ml. The same enzyme solution used in part d (absorbance at 280 nm = 0.485) was diluted 2.00 ml in 250 ml as in I, then again 2.00 ml in 200 ml. Portions of 1.00 ml of this twice diluted enzyme were added at t = 0 to each of the test tubes of buffered substrate. The reaction was stopped in just 10.0 minutes by adding perchloric acid a suitable reagent was added to provide for a colorimetric determination of the product. The results were as follows ...

Ultraviolet) instrument and from SAGE II (Stratospheric Aerosol and Gas Experiment II), together with supporting data from ozonesondes and satellite instruments such as SME (Solar Mesosphere Explorer) and TOMS (Total Ozone Mapping Spectrometer). The model interpolates monthly ozone values to its timestep and this time-varying ozone repeats every simulation year. The model currently does not allow the ozone to become interactive, neither does it represent any change in ozone due to chemical processes, although work is underway to incorporate these features.

The overall current-voltage relationship is complex and very different for different experimental conditions. In Thought Experiment I, we begin to examine its characteristics, and continue to look deeper in Experiments II and III. These exercises help to define the general parameters discussed thus far in specific operational scenarios. For all three Thought Experiments, consult Fig. 5.1. 

The reason why Curve B looks different from Curve A is that the added redox couple allows the electrons to jump across the interface (capacitor) at much lower energy (voltage) than before. As a result, it shunts (depolarizes) the capacitor. Thus, the energy stored in the capacitor has been used to oxidize or reduce the added depolarizer in the solution. We can make four observations from Thought Experiment II.
