Fractal analysis of topography and reflectance surfaces
… comparing the calculated with the theoretical D values of the theoretical fractal models. The application of appropriate methods to self-similar or self-affine fractals is essential due to different theoretical assumptions of the methodologies. The ruler dimension is different from the spectral …

Species Diversity of Benthic Macroinvertebrates in the Des Moines River, Iowa
… Species diversity (D) and redundancy (R) values were used to calculate standardlzed distance (SD) values. The indices were analyzed statistically. Findings. The average D values ranged from 1.62 to 1.94. Mean standardized distance (SD) values were lowest immediately above the metropolitan …

Isolation of immunoglobulins from cheese whey and milk using ultrafiltration and immobilized metal affinity chromatography
… of IgG at 62°, 66°, 70°, 74°, 78° and 80°C. D values were obtained from the first-order destruction curves. The D values were used to plot a thermal resistance curve, and D values were extrapolated for temperatures used for the shelf life study. D values extrapolated were 1.77 x 10¹⁴ yr at 4°C, …

Population genetics of the genus Transennella (Bivalvia)
… two populations of each morphotype. The I and D values derived from intraspecific comparisons of Transennella tantilla populations are 0.99 and 0,004; for Transennella sp., the I value is also 0.99 and D is 0,002. The I and D values obtained from interspecific comparisons (T. tantilla versus T, …

Increase in heat resistance of <u>Listeria monocytogenes</u> Scott A by sublethal heat shock
… heat shock condition was 45°C for 20 min where D-values at 55°C increased 2.3 fold in non-selective agar and 1.6 fold in selective agar in comparison to non-heat shocked cells. However, cells heat shocked at 48°C for 10 min gave more consistent results; these cells were heated at 50, 55, 60, and …

Ground water - surface water interactions in the lower Virgin River area, Arizona and Nevada
… isotopically enriched ({dollar}\delta{dollar}D values between {dollar}-{dollar}91 and {dollar}-70\perthous{dollar}) and has the lowest dissolved solids concentrations of all the waters sampled. Deep ground water is the most isotopically depleted of the waters with {dollar}\delta{dollar}D values …

Graphene Field-Effect Transistors on p-doped Semiconductors for Photodetection
… for both p-doped substrates. NEP and D* values of these detectors have been characterized along with response time characteristics. The NEP and D∗ values for both detectors are around 10−15 W/√ and 1012 Jones respectively, indicating a sensitive photodetection. The response time …

Growth and survival of Clostridium botulinum type E in pasteurized oysters
… the spores survived pasteurization at 550 C; D-values ranged from 65 to 100 min at 700 C and 880 to 1300 min at 550 C. When tubes of oyster homogenate were inoculated with 1x103 type E spores/ml and stored at 3, 6, 12, and 30oC, no growth was observed; however, when the inocculum was increased …

Heat resistance of Salmonella typhimurium and Listeria monocytogenes in suspension and in a biofilm matrix
… was no significant difference (p>0.05) in D-values between treatments. There was a significant difference (p<0.001) between the D-values for Salmonella and Listeria. The second method used a laboratory scale HTST pasteurizer to determine the difference in heat resistance of the same organisms …

The effect of heat shock, growth atmosphere, and recovery atmosphere on the survival of Escherichia coli 0157:H7 to heat
… resulted in a significant increase in the mean D values of both aerobically grown and anaerobically grown cells. The largest increase in mean D values was observed in aerobically grown non-heat-shocked cells, which increased by a factor of 2.3 when plated anaerobically instead of aerobically. The …

Aerodynamic Properties of the Inboard Wing Concept
… the same span as the full configuration. The L/D values found for this non-optimized configuration were modest compared to those for conventional transports. The vertical tails were shown to act as winglets, reducing drag and increasing L/D. These results suggest areas for substantial improvement …

Development of amyloid beta binding bifunctional chelators for diagnosis of Alzheimer’s disease
… the octanol/PBS distribution coefficient (log D) values for prediction of blood-brain barrier (BBB) permeability. YW-13 shows the best amyloid staining but suffers from the low log D value of anionic 64Cu complex. Therefore, we adapted the compound design by replacing one carboxylate arm with a …

Detection, activity and resistance to thermal inactivation of peroxidase in the blue crab (Callinectes sapidus)
… at a slower rate due to heat stable isozymes. D values obtained for the enzyme based on the second straight line segment were D80=47 min, D110=18.2 min and D150=11.2 min. A "z" value of 92 F was also obtained for the enzyme.

Dielectric and electromechanical properties of barium and zirconium co-doped sodium bismuth titanate
… NBT-BT-NBZ compositions surpass highest reported values of strain and d₃₃ for polycrystalline PMN and PLZT and single crystal PMN conventional lead electrostrictors. Predominantly ferroelectric room temperature unipolar actuation in polycrystalline NBT-14BT-3NBZ at 0.05 Hz was observed to be …
