I compares alkylsulfone isomers 22 and 41 to tied-back i-propylsulfone sulfonylurea 4Q. The numbers are the percent control of a plant species. The tied-back sulfone is the most active on broadleaf weeds, cocklebur and sicklepod. It is weaker on barnyard grass but better on wild oats, than the open-chained sulfonylureas.

I compares calculated concentrations of benzene, toluene, and ethylbenzene at several locations near the refinery with reported values for typical urban, rural, and remote settings from past EPA studies .

I compares glucose with ascorbic acid for a number of oxidative parameters. The higher rate of oxidation, oxidant production, and concomitant protein fragmentation and generation of fluorescence products on albumin by ascorbic acid is also accompanied by aldehyde products able to bind to proteins . A number of studies have shown that ascorbic acid can decrease the oxidation of LDL by copper, the process usually occurring over several hours. Such observations are not indicative of an antioxidant activity.

I compares operating costs of the various systems. Next, it being understood that the injected ozone dosages vary according to the process. Table II gives the actual electrical consumption for treating 1000 cubic meters of water.

I compares properties of Dimersol Dimate and C3 alkylate. In studying this table one sees a basic difference between dimate and C3 alkylate volatility manifested in distillation and RVP. In gasoline blending this becomes important when one is blending with reformate. To illustrate, we will show a series of bar charts giving the RON s of consecutive individual 10 volume increments of full boiling range gasolines.

I compares results achieved when seven variables that may affect the performance of a particular catalyst were tested one-at-a-time with results from a statistical design approach. In this comparison, a shift in measured performance is assumed to be real if it represents at least twice the uncertainty of the measuring technique. The one-at-a-time strategy, still prevalent among many catalyst researchers, requires 48 experiments to determine with 95 confidence which variables significantly impact catalyst performance. Whereas, with the fractional factorial approach, this same information was obtained in only 16 experiments with a 98.5 confidence level. The fractional factorial approach also shows possible interactions among the variables the classical one-at-a-time approach does not.

I compares results obtained in this manner with those reported by Arro Laboratories for 3 broad-distribution PVC standards. Table II does the same for several PVC commercial suspension resins from Sha-winigan, using a Mark-Houwink expression as a basis for comparison of M W values.

I compares selected bond lengths for complexes 1, 2, 3, and 4. As was observed by Maroney and coworkers for an octahedral complex containing both Ni-thiolate and Ni-sulfinate groups, the Ni-Ssulfinyl distance of 2.140 A. The short N1-S02R distance is accounted for by the decrease in radius of S 2 in the sulfinate as compared to S in the thiolate.

I compares some estimated sensitivities for various elements by the four methods under conditions chosen to make the comparisons as objective as possible. Flame or plasma emission and atomic absorption involve direct utilization of liquid sample. The actual concentration of constituent in the sample is thus the logical way of expressing detection limits and is used here. In colorimetry, however, there are usually dilution and concentration steps in the procedure which vary greatly from method to method hence, direct comparison from element to element is difficult. The method of measurement is also far from uniform, and for this reason we have chosen to express the limit of detectability as p.p.b. . Obviously, accurate quantitative determinations require much higher concentrations—e.g., a factor of 100 or more.

I compares some techniques commonly used for either structure determination or mass measurement. Estimates given in Table I are typical capabilities in 1997 individual cases may be much better or worse than stated. Only STEM and small-angle scattering provide both mass and structural information simultaneously.

I compares the chemical and physical properties of two hydroxychromium montmorillonites prepared by reaction of a Na -exchanged Wyoming montmorillonite unit cell formula

I compares the conditions and results of this operation to those for conventional SRC for Illinois 6 coal. At the short residence time, the coal conversion determined by pyridine solubility is 89 compared to 95 at conventional SRC conditions. The hydrogen consumption and production of light gases are reduced significantly at short residence time, while the SRC yield is increased.

I compares the conversion of NO and the two hydrocarbons, as well as the selectivity to N2 , to the results without an added hydrocarbon reductant The conversion of acetone is greater than can be accounted for by the reduction of NO according to the following reactions

I compares the dominant interstellar ice constituents with the inferred components from several comets and gives their abundance with respect to H2O. Detailed reviews of this topic can be found elsewhere 6,7 .

I compares the experimental and calculated Kell s lor lour critical conllguratlons. The calculated values were obtained using the AIM-6, one-dlmenslonal dillusion code with a 16-group ciws-sectlon library obtained Irom Los Alamos. The method ol computation required agreement between KeU s comiHited in slab and cylindrical geometry. Equivalence in Kelt between reflected cores and bare cores provided energy independent transverse buckling terms,
