Negative influences

In order to minimize the probe heating effect (measure disturber), the number of the measure points will be 80x80 (the sweeping time negatively influences the probes ), for example ... 

Conversion of 3-chloropentafluoropropene to 1 chlorodifluoromethyl-1,2,2-trifluorooxirane in alkaline solution is negatively influenced by the high nucleophilic reactivity of allyhc chlorine [14] The reaction is performed at very low temperature to favor the attack of hydroperoxyl anion in a competition with hydroxyl anion Acceptable yields of 31-38% are obtained in the presence of a phase-transfer catalyst [14] (equation 8)... 

However, it seems that the presently small attention being given to SFC has also a negative influence on the interest in SFE, where the latter seems a much more promising technique. 

The polyene Amph B (intravenous formulation) has the broadest spectrum, is fungicidal and shows its superiority in immunosuppressed patients. Its only drawback is its infusion-related toxicity and its negative influence on renal function. Acute reactions to Amph B - usually fever chills, rigor and nausea - can be... 

The negative influence of the organic layer also consists in reducing the concn of DNT in the acid phase. This occurs when the organic phase is composed mainly of molten TNT. 

Air injection This measure has a positive effect on the silanization efficiency without negatively influencing the properties of the material. The combination of air injection with working in an open mixer adds the positive effects of the two measures. 

To avoid gas-liquid mass transfer Hmitation, which would have a negative influence on productivity, in correctly operated bioreactors there are turbulent flow conditions with more or less pronounced turbulence, for which the Reynolds stress formula (Eq. (2)) can be used. Whereas, as a rule there is fully developed turbulent flow in technical apparatuses (see condition (6) and explanations in Sect. 8), this is frequently not the case in laboratory fermenters. Equations (3) and (4) are then only valid to a limited extent. 

The qualitative differences of the behavior of parameter b under sensitivity or MCCC analyses are less obvious, even if its (negative) influence on volume size seems to increase faster according to MCCC. 

Hydrodewaxing Selective hydrocracking of paraffins from oil fractions or products to prevent wax precipitation (negative influence on cold flow properties) ... 

Figure 1. Schematic diagram showing a TRU-spec extraction chromatography method for separation of uranium, thorium, protactinium, and radium from a single rock aliquot. Further purification for each element is normally necessary for mass spectrometric analysis. Analysis of a single aliquot reduces sample size requirements and facilitates evaluation of uranium-series dating concordance for volcanic rocks and carbonates. For TIMS work where ionization is negatively influenced by the presence of residual extractant, inert beads are used to help remove dissolved extractant from the eluant.

The quantitation of spontaneous sleep-waking cycles in 5-HTiB receptor knockout mice has shown that REMS is increased whereas SWS is reduced during the light phase (Boutrel et al., 1999). On the other hand, systemic administration of CP-94,253 to wild-type mice tends to suppress REM, whereas the 5-HTiB antagonist GR 127935 induces the opposite effect. Thus, the limited available evidence indicates that 5-HTib receptor activation facilitates the occurrence of W and negatively influences REMS. 

Surfactants, not surprisingly, exert a highly significant influence on the fluorescence of FBAs in solution. This effect is associated with the critical micelle concentration of the surfactant and may be regarded as a special type of solvent effect. Anionic surfactants have almost no influence on the performance of anionic FBAs on cotton, but nonionic surfactants may exert either positive or negative effects on the whiteness of the treated substrate [33]. Cationic surfactants would be expected to have a negative influence, but this is not always so [34]. No general rule can be formulated and each case has to be considered separately. 

In the case of by-product formation that negatively influences the course of reaction, the same procedures can be integrated as in the case of limitations by the equilibrium (Section 4.3.3). 

Approximately 30-40% of patients will not respond to a given antidepressant and 60-75% may fail to achieve complete remission [16]. Consequently, in its least restricted definition, treatment resistance could be detected in the majority of depressed patients under treatment. Moreover, prior treatment failure negatively influences the response to subsequent antidepressant treatment, decreasing the odds of treatment response by a factor of 15-20% for each failed treatment [17]. The delayed onset of symptom relief (which takes three to eight weeks to occur) and the presence of adverse drug reactions contribute significantly to low treatment compliance. 

Chiou et al. (1998) attributed the enhanced partitioning of PAHs with respect to other HOCs to relatively high compatibility between the cohesive energy densities of PAHs and the aromatic components in SOM. However, the difference in Koc values between soils and sediments is related to the difference in polar group, rather than aromatic carbon, contents (Kile et al. 1999). The authors concluded that the content of polar groups (O-aryl and carboxyl C) has a large negative influence on Koc values, and hence on HOC sorption in soil and sediment. 

Although the FTS is considered a carbon in-sensitive reaction,30 deactivation of the cobalt active phase by carbon deposition during FTS has been widely postulated.31-38 This mechanism, however, is hard to prove during realistic synthesis conditions due to the presence of heavy hydrocarbon wax product and the potential spillover and buildup of inert carbon on the catalyst support. Also, studies on supported cobalt catalysts have been conducted that suggest deactivation by pore plugging of narrow catalyst pores by the heavy (> 40) wax product.39,40 Very often, regeneration treatments that remove these carbonaceous phases from the catalyst result in reactivation of the catalyst.32 Many of the companies with experience in cobalt-based FTS research report that these catalysts are negatively influenced by carbon (Table 4.1). 

The purified product is presented as a solution and contains sodium citrate, EDTA, sodium chloride and polysorbate 80 as excipients. A daily (s.c.) injection of 100 mg is recommended for patients with rheumatoid arthritis. This inflammatory condition is (not surprisingly) characterized by the presence of high levels of IL-1 in the synovial fluid of affected joints. In addition to its pro-inflammatory properties, IL-1 also mediates additional negative influences on the joint/bone, including promoting cartilage degradation and stimulation of bone resorption.
