Although the reduction of contact resistance at 7c provides evidence for the induction of high temperature superconductivity into these organic conductors, the possibility of spreading resistance contributing to the measurement was noted previously [4]. This phenomenon occurs commonly in structures such as these when the resistance of one element, in this case the cuprate superconductor, drops suddenly to zero. Therefore, it is desirable to search for additional evidence for the organic proximity effect in crystalline organic conductors. [Pg.1050]

Biodeterioration. For objects made out of organic materials, mold and insect attack are a principal cause of damage. Microbiological organisms can also be responsible for serious deterioration of outdoor stone. Museums, especially storage areas, are quite conducive to providing the conditions in which infestations can occur. Objects are stored in close proximity, and left untouched for prolonged periods, often with Htde if any ak movement. [Pg.429]

The presence of organisms (large or small) in proximity to corrosion by itself is not proof of biologically influenced corrosion, any more than a correlation of lunar phases with stock market fluctuations establishes a lunar-financial connection. It should be stressed vigorously that all evidence must be consistent with any single corrosion mode before a definitive diagnosis can be made (see Critical Factors above). Further, all alternative explanations must be carefully examined. [Pg.146]

You will note that the oxygen atoms attached to carbons 5 and 12 in 43 reside in proximity to the C-9 ketone carbonyl. Under sufficiently acidic conditions, it is conceivable that removal of the triethylsilyl protecting groups would be attended by a thermodynamically controlled spiroketalization reaction.30 Indeed, after hydro-genolysis of the C-26 benzyl ether in 43, subjection of the organic residue to the action of para-toluenesulfonic acid in a mixture of methylene chloride, ether, and water accomplishes the desired processes outlined above and provides monensin methyl ester. Finally, saponification of the methyl ester with aqueous sodium hydroxide in methanol furnishes the sodium salt of (+)-monensin [(+)-1], Still s elegant synthesis of monensin is now complete.13... [Pg.246]

An aspect that is difficult to treat is the nature of the boundary between the adsorbate layer and the bulk of the solution. Solvent molecules are now in contact with an organic layer and the kind of interaction is expected to differ substantially from that with a bare metal surface. The layers of solvent molecules in the immediate proximity of the adsorbate might exhibit some preferential orientation, which is not explicitly accounted for in Eq. (36), and this adds some additional ambiguity to the physical interpretation of the results. [Pg.28]

The detailed analysis of proximal ecological events is the only means by which we can reasonably hope to inform our guesses about the ultimate causes of the ways in which organisms behave. Harper (1982)... [Pg.32]

The interfacial transfer kinetics were then investigated by perturbing the equilibrium, through the depletion of Cu + in the aqueous phase, by reduction to Cu at an UME located in close proximity to the aqueous-organic interface. This process promoted the transfer of Cu into the aqueous phase, via the transport and decomplexation of the cupric ion-oxime complex, resulting in an enhanced steady-state current at the UME. Approach curve measurements of i/i oo) vs. d allowed the kinetics of the transfer process to be determined unambiguously [9,18]. [Pg.322]

FIG. 13 Schematic illustration of the SECM feedback mode based on a simple ion-transfer reaction. Cations are transferred from the top (organic) phase into the aqueous solution inside the pipette tip. Positive feedback is due to IT from the bottom (aqueous) layer into the organic phase. Electroneutrality in the bottom layer is maintained by reverse transfer of the common ion across the ITIES beyond the close proximity of the pipette where its concentration is depleted.

The prostate is a heart-shaped, chestnut-sized organ that encircles the portion of the proximal urethra that is located at the base of the urinary bladder. The prostate produces secretions which are part of the ejaculate. [Pg.792]

The gastrointestinal microflora provide another potential site for drug metabolism within the GIT, and it has received some attention. In normal subjects the stomach and proximal small intestine contain small numbers of microorganisms. Concentrations of these organisms increase toward the distal end of the intestine. A wide variety of aerobic and anaerobic organisms are present in the gut. The microflora, derived primarily... [Pg.67]

Cramped spaces and those with poorly placed materials increase the potential for accidental releases due to constricted and awkward movement in these areas. A determination should be made as to whether materials can be stored in a more organized and safer manner (e.g., stacked, stored in bulk as opposed to individual containers, etc.). The proximity of materials to their place of use should also be evaluated. Equipment and materials used in a particular area should be stored nearby for convenience, but should not hinder the movement of workers or equipment. This is especially important for waste products. Where waste conveyance is not automatic, waste receptacles should be located as close as possible to the waste generation areas, thereby preventing inappropriate disposal leading to environmental releases. [Pg.5]
