Transformation passive

In case the coordinate system is rotated clockwise or the vector is rotated counterclockwise (passive transformation) some elements of the matrix change its sign ... 

Here the viewpoint oi passive transformations has been taken, i.e., one physical event or system is described with reference to two different inertial frames IS and IS, cf. Figure 2.1. 

A solid phase extraction step for the reduction of the matrix oil components was optimized. Because of the hydrophobic characteristics of the additives, a reversed phase chromatographic separation method was used and optimized. The so developed method was used for the analysis of inhibited and passivated transformer oils (33). 

Remember that a forward-mode transformer reflects the impedance from one side to the other. This means that if drivers are single-ended on the primary side (i.e., active turn-on, passive turn-off) the power switch will still have a slow turn-off. If totem-pole outputs are driving the primary are used, the power switch s response will be fast.

Tantalum is severely attacked at ambient temperatures and up to about 100°C in aqueous atmospheric environments in the presence of fluorine and hydrofluoric acids. Flourine, hydrofluoric acid and fluoride salt solutions represent typical aggressive environments in which tantalum corrodes at ambient temperatures. Under exposure to these environments the protective TajOj oxide film is attacked and the metal is transformed from a passive to an active state. The corrosion mechanism of tantalum in these environments is mainly based on dissolution reactions to give fluoro complexes. The composition depends markedly on the conditions. The existence of oxidizing agents such as sulphur trioxide or peroxides in aqueous fluoride environments enhance the corrosion rate of tantalum owing to rapid formation of oxofluoro complexes. 

After emission, contaminants may be partitioned among the terrestrial, aqnatic, and various atmospheric phases, and those of sufficient volatility or associated with particles may be transported over long distances. This is not a passive process, however, since important transformations may take place in the troposphere during transit so that attention should also be directed to their transformation products. 

U.S. EPA defines MNA as the reliance on natural processes, within the context of a carefully controlled and monitored site cleanup approach, to achieve site-specific remediation objectives within a time frame that is reasonable compared to that offered by other more active methods. The natural processes include biodegradation, dispersion, dilution, sorption, volatilization, stabilization, and transformation. These processes reduce site risk by transforming contaminants to less toxic forms, reducing contaminant concentrations, and reducing contaminant mobility and bioavailability. Other terms for natural attenuation in the literature include intrinsic remediation, intrinsic bio-remediation, passive bioremediation natural recovery, and natural assimilation. 30... 

The Fourier transforms for both films are again quite similar, but as for the ex situ measurements, the chromate-passivated films appear to have a more glassy structure. It should be mentioned that these studies employed a rather limited data range which makes spectral differentiation difficult. 

Although the absence of paracellular transport across the BBB impedes the entry of small hydrophilic compounds into the brain, low-molecular-weight lipophilic substances may pass through the endothelial cell membranes and cytosol by passive diffusion [7]. While this physical barrier cannot protect the brain against chemicals, the metabolic barrier formed by the enzymes from the endothelial cell cytosol may transform these chemicals. Compounds transported through the BBB by carrier-mediated systems may also be metabolized. Thus, l-DOPA is transported through the BBB and then decarboxylated to dopamine by the aromatic amino acid decarboxylase [7]. 

Breathing is a vehicle of spiritual experience, the link between the physical body and the mind. It is the first step in the transformation of the body from a more or less passive and unconscious functioning physical organ into a vehicle for or tool of a perfectly developed and enlightened mind, as demonstrated by the perfection and radiance of the Buddha s body. 

Adsorption of TU on active and passive iron electrodes was studied by Bockris et al. using radiotracer and Fourier Transform Infrared Spectroscopy techniques. The high values of AG° (the standard states 0° = 0.582 and c° = 1 mol T ) equal to -17.20 kJ/mol and -18.98 kJ/mol have been obtained for the active and passive iron electrodes, respectively. They are markedly higher than those obtained for other metals (Table 1).
