Significant factors

In general, stabilizers function by reaction with proplnt decompn products. A number of methods have been described and a preliminary evaluation of these methods was conducted by several labs under a cooperative program. Based on results from these screening tests, the PicArsn spec tropho tome trie methods for available stabilizer and primary degradation products were selected for further study. The initial phase of this program was an attempt to standardize the necessary spectrophotometric factors. Significant differences with regard to the factors obtained... [Pg.944]

NOTE In practice, the skills required to correctly and comprehensively interpret the various water analyses and provide suitable recommendations for action are not widely available outside the ranks of the service companies. When selecting a water treatment service provider therefore, this element should factor significantly in the vendor evaluation process. [Pg.126]

Omitting for simplicity Hie factor significance in the result obtained, we then write... [Pg.702]

Ikonopisov284 has conducted a systematic study of breakdown mechanisms in growing anodic oxides. He has enumerated factors significantly affecting the breakdown (nature of the anodized metal, electrolyte composition and resistivity) as well as those of less importance (current density, surface topography, temperature, etc.). By assuming a mechanism of avalanche multiplication of electrons injected into the oxide by the Schottky mechanism, Ikonopisov has correctly predicted the dependence of Ub on electrolyte resistivity and other breakdown features. [Pg.481]

Combined influence of both of the above factors significantly limits the performance and operation capability of the NiOx electrodes of agglomerate type in the asymmetric C/NiOx capacitors. Good initial performance may change for accelerated failure either in the floating mode or in heavy duty cycling mode of operation. [Pg.52]

Equation 9.5 shows that for an acceptable retention factor, the diffusion coefficient and particle size of the packing are the primary variables that can be varied to affect the N/tf An increase in the diffusion coefficient or a decrease in the particle size causes an increase in N/tf If the diffusion coefficient can be increased without impacting the retention factor significantly, then significant increases in separation speed will result. To minimally impact the retention factor the solvent strength of the mobile phase must be maintained. [Pg.425]

However, biomagnification factors significantly different from 1 may also reflect real processes building up the effective concentrations in a given organism s tissues. Said more accurately, the chemical activity or fugacity of the compound may prove to be greater as one moves up the food chain ... [Pg.367]

Obama et al. [9] reported two factors significant in modeling structure- Vm relationships in isomeric dialkyl ethers (1) the existence of side chains and (2) the difference between the numbers of C atoms in the two alkyl groups. The first factor causes Vm to increase (i.e., a branched dialkyl ether has a greater Vm value than that of its linear isomer) ... [Pg.41]

The intermediate phase of the innovation process, where innovation is transformed into a product with an economic impact, is the stage at which action by an institution can enhance the economic impact of the discovery. Three factors significantly increase rates of innovation during this stage. The first is the... [Pg.99]

Let us now compare the loadings obtained after utilizing a standard rotational procedure (Varimax). In Tab. 5-7 we find the first factor loaded only by Al and Fe. (Using insider knowledge , should we relate this to the fact that these are the only elements in the interlaboratory comparison determined by a gravimetric method. .. ) All other factors express the importance of single elements. The sole exception is Ti If we keep our limit of 0.7 for a coefficient Ti does not contribute to any of the factors significantly. [Pg.176]

As seen from table 4, inclusion of scaling factor significantly decreases the value of It is expected to decrease more significantly for RE ions in crystals, since all./ manifolds are split by crystal field and number of levels N increases drastically. For example, when similar analysis has been performed for the lowest levels of LaF3 Eu3+ by Brik et al. (2006), the value of arms turned out to be 21.6 cm-1. The consistency in energy values and their assignments... [Pg.18]

In the 20th century, and especially in its second half, under the influence of climatic and anthropogenic factors, significant changes have occurred in the diversity of the flora and fauna of the Black Sea. Among the factors mentioned, the occasional and sometimes intentional introduction of alien species of animals and plants is a global phenomenon that has not avoided the Black Sea as well. As a result, the Black Sea became a basin for many alien species of different origins. [Pg.376]

In the study of a simple reaction dependent on temperature, pH, reaction time and catalyst concentration, are the interactions between these factors important In particular, are higher order interactions (between more than two factors) significant ... [Pg.24]

In 23 patients with obsessive-compulsive disorder who had not responded to a 6-month course of fluvoxamine (300 mg/day), olanzapine (5 mg/day) was added in an open comparison (28). There was a significant reduction in the mean score on the Yale-Brown Obsessive-Compulsive Scale concomitant schizotypal personality disorder was the only factor significantly associated with a response. The most common adverse effects were mild to moderate weight gain and sedation. [Pg.302]

This effect can be modulated by environmental factors. Significant increases were found in skin proanthocyanidin content, proportion of (-)-epigallocatechin, and average DP in berries from zones with a low vine vigor (Cortell et al. 2005). In reaction to sun exposure, skin proanthocyanidin content tends to increase, particularly trihydroxylated subunits and mDP is enhanced (Downey et al. 2004 Cortell and Kennedy 2006). Shaded fruits reached a lower maximum in proanthocyanidin content than sun-exposed ones but the contents at harvest were similar. Most authors agree that water stress had only slight effects on tannin composition (Ojeda et al. 2002 Kennedy et al. 2002 Castellarin et al. 2006). Seed flavanol composition seems hardly affected by environmental factors. [Pg.473]

AAF labeling can also be used to prepare large quan tides of nonradio-acdve hybridizadon probes. It is simple and inexpensive. However, it is still not widely used. This is partly caused by the potent genotoxic effect of the carcinogen. In addidon, the sensitivity of probes labeled by this method has to be confirmed. These two factors significantly limit the general usefulness of this method for the preparadon of non-radioacdve molecular probes. [Pg.407]

Coating the glazing surfaces with low-e (low eraissivity) films reduces the /-factor significantly. For multiple-glazed units, it is adequate to coat one of the two surfaces facing each other. [Pg.557]
