factorial and split-plot designs are two statistical procedures used to conduct agricultural field experiments. both designs are used frequently to quantify the main and interaction effects of two or more factors. however, split-plot design is recommended for specific situations depending on major and minor goals of the study, characteristics of the factors, and precision of statistical testing...

An anodic aluminum oxide (AAO) template was formed by a two-step anodization process. Carbon nanotubes (CNTs) were successfully synthesized along with AAO pores and the diameters of CNTs equaled those of AAO pores. The lengths of CNTs during a chemical vapor deposition synthesized process on the AAO template were effectively controlled. These AAO-CNTs exhibit excellent field emission with a low...

The preparation of a new family of mixed transition metal/lanthanide clusters is reported. The reaction of [Mn3O(O2CPh)6(py)2(H2O)] with Ln(NO3)3 (Ln = Nd, Gd, Dy, Ho, and Eu) in a 1:2 molar ratio in MeOH/MeCN (1:20 v/v) leads to dark crystals in 55-60% isolated yield of complexes all containing the [Mn11Ln4]45+ core. The Dy compound has been found to give out-of-phase AC susceptibility signals...

These conditions do not provide a measure of driving force as needed for a Boltzmann fit to obtain conductance parameters of midpoint and slope factor. Therefore, we have analyzed the original dataset using the asymptote for the relative change in current amplitude to estimate driving force and plot G-V relations. G/GMAX was plotted as a function of voltage, and these curves were fit with a Bol...

Krejzar V., Mertelík J., Pánková I., Kloudová K., Kůdela V. (2008): Pseudomonas marginalis associated with soft rot of Zantedeschia spp. Plant. Protect. Sci., 44: 85–90. For the first time in the Czech Republic, bacteria identified as Pseudomonas marginalis, Pectobacterium carotovorum subsp. carotovorum and Pseudomonas putida were isolated from tubers of Zantedeschia spp. with symptoms of tuber...

OBJECTIVE To develop a simple, selective, sensitive and accurate high-performance thin layer chromatography (HPTLC) method to determine the quantity of hesperidin in different varieties of citrus fruits. METHODS The method was carried out in aluminum-backed silica gel 60 F254 plates with ethyl acetate-methanol-water 15:3:2 (%, v/v) as mobile phase. RESULTS A compact band was obtained for he...

Human glutathione S-transferase omega 1-1 (hGSTO1-1) is a newly identified member of the glutathione S-transferase (GST) family of genes, which also contains alpha, mu, pi, sigma, theta, and zeta members. hGSTO1-1 catalyzes the reduction of arsenate, monomethylarsenate (MMA(V)), and dimethylarsenate (DMA(V)) and exhibits thioltransferase and dehydroascorbate reductase activities. Recent evidenc...

We have investigated the transport properties in the direction perpendicular to the substrate of regioregular polys3-hexyl-thiophened of different molecular weights sMWd in a diode geometry. In these devices, which exhibit space-charge-limited behavior, we find that the mobility values at room temperature increase from 1.33310−5 cm2/V s to 3.30310−4 cm2/V s as the MW is increased from 2.9 to 31...
