Nevertheless, portable fuel cells are in their infancy. Investment costs to generate 1 kilowatt are stiU very high, around 10,000 to 100,000 per produced kilowatt. However, portable fuel cells should become cost competitive ( 5,000/kW) with lithium-ion batteries, commonly used in laptop computers,

CTC leaders should evaluate the most appropriate role they can play in the fuel cell arena. Those colleges that determine they should be involved in this technology should plan a limited involvement for the near future, but prepare themselves to expand their programs quickly if there is rapid growth in the fuel cell industry. The Potential Impacting Factors section of this report lists a number of possible trends, events, or decisions that might significantly accelerate fuel cell adoption.

Despite the potential impact of novel photosynthetic routes based on these developments, the most ambitious application remains in the conversion of solar energy into electricity. Dvorak et al. showed that photocurrent as well as photopotential response can be developed across liquid-liquid junctions during photoinduced ET reactions [157,158]. The first analysis of the output power of a porphyrin-sensitized water-DCE interface has been recently reported [87]. Characteristic photocurrent-photovoltage curves for this junction connected in series to an external load are displayed in Fig. 22. It should be mentioned that negligible photoresponses are observed when only the platinum counterelectrodes are illuminated. Considering irradiation AM 1, solar energy conversions from 0.01 to 0.1% have been estimated, with fill factors around 0.4. The low conversion... 

As mentioned above, there are characterization factors for a number of different impact categories, e.g. acidification, eutrophication, climate change, human toxicity and ecotoxicity. However, characterization factors are missing for many additives, especially for human toxicity and ecotoxicity, which makes it difficult to assess the potential impact that a product will cause during its entire life cycle. A major reason that characterization factors are often missing is the lack of data regarding substance properties, such as physical chemical properties and toxicity. 

The assessment of risk of the potential incidence or escalation of conflict is called integrated because of the broad scale of factors that are considered (political, economic, social, demographic and environmental. The integrated risk assessment manages the complexity in the relationship between the consequences of stress and inhibiting or facilitating factors in order to determine which factor has the most potential impact on the incidence or escalation of conflict. 

Many factors may confound the assessment of the D DI potential of early discovery compounds [93], Limited or no solubility data exist to understand the likelihood that the compound will precipitate out of an in vitro incubation. The compounds have generally not been analyzed from a spectroscopic perspective their characteristics may interfere with a fluorogenic DDI assay. Metabolism data are typically not available. The binding of a compound to plasma proteins or microsomal incubation constituents is not well understood, which may lead to underprediction of its inhibitory potential. The compounds are typically delivered in DMSO, which may cause solvent-related inhibition of the enzymatic assay. Also, since little is known about in vivo concentrations or projected dose, framing the consequences of an early DDI in vitro experiment may be difficult. With these factors in mind, general experimental paradigms have been developed to help minimize their potential impact. 

To understand whether cognitive function and mood disorders are cooperatively influenced by genetic factors in AD and to know the potential impact that conventional neuroprotection can exert on mood disorders, we studied the effect of the therapeutic CNLA protocol on anxiety in AD and the differential APOE- and ACE-related responses distinguishing the influence of monogenic and bigenic variants on emotional conditions. 

In passing, we should also mention one additional microstructural factor potentially impacting the overall electrode performance constriction of the ionic current in the electrolyte near the electrode/electrolyte interface. To better understand this effect, consider a circular disk electrode of diameter d immersed in a semi-infinite electrolyte of conductivity... 

Determining fireproofing needs based on the probability of an incident considering industry experience, the potential impact of damage for each fire-scenario envelope (see 7.3.2.2), and technical, economic, environmental, regulatory, and human risk factors. 

Thus, the potential Impact of an allelochemical on plant growth should be evaluated with regard to both the presence of associated allelopathic compounds and the influence of other chemical and physical conditions in the environment. Certainly allelochemical action is not an isolated event, and from the standpoint of plant functions, the controversy between competitive and allelochemical Interference loses some of its significance. Allelochemical action needs to be regarded with a holistic view where one stress may reinforce, or magnify, another. From this perspective, inhibition of plant growth is not so much a matter of which factor is most detrimental instead it is determined by the interaction of multiple stresses. 

The impact of life events as potential risk factor in the development of anxiety disorders has been evaluated in several epidemiological studies, hi almost all studies evidence was found for an association between childhood adversities...

As indicated above, the latent period preceding the appearance of an induced neoplasm may vary with the nature of the carcinogenic stimulus (initiation, promotion, etc.), type of neoplasm, age at exposure, and other factors. These variables must, therefore, be taken into account in estimating the potential impacts of a carcinogen.
