    Notes: Post-war survey photography provides a detailed record of the great changes which have occurred in this period. Pictures of urban expansion, land reclamation, quarrying and infilling and industrial decline can be seen in three dimensions and be measured and analysed. The record of change is of great practical significance to engineers.

    Synthetic-Fuel Plants: Potential Tumor Risks to Public Health (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Risk analysis 5 (1985), S. 0 
    Details
    ISSN: 1539-6924
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: This article quantifies potential public health risks from tumor-producing pollutants emitted from two synthetic-fuel plants (direct liquefaction—Exxon Donor Solvent; and indirect liquefaction—Lurgi Fischer-Tropsch) located at a representative site in the eastern United States. In these analyses gaseous and aqueous waste streams were characterized; exposures via inhalation, terrestrial and aquatic food chains, and drinking water supplies were modeled. Analysis suggested that emissions of “polycyclic aromatic hydrocarbons,”“aromatic amines,”“neutral N, O, S heterocyclics,”“nitriles,” and “other trace elements” pose the largest quantifiable risks to public health. Data and analysis for these pollutant categories should be refined to more accurately match compound-specific estimated exposure levels with tumorigenic potency estimates. Before these results are used for regulatory purposes, more detailed analysis for selected pollutant classes are needed, and more sophisticated aquatic exposure models must be developed. Also, differences in geographic scales among the environmental transport models used need to be rectified.

    An Analysis of Damage to U.S. Soybean Yields from 1982 Acid Deposition Levels (1987)
    Oxford, UK : Blackwell Publishing Ltd
    Risk analysis 7 (1987), S. 0 
    Details
    ISSN: 1539-6924
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Experimental data were compiled for seven soybean varieties studied at four different locations in the U.S. for a period of one to three years. Three dose–response functions (linear, quadratic, and Weibull) were fitted, as appropriate, to the experimental data. Effects of acid deposition on soybean yields were estimated by combining variety-specific dose–response and production data. These calculations suggest that U.S. soybean production (2.2 billion bushels in 1982) would increase by 3.2 million bushels with a 10% reduction in 1982 hydrogen ion concentration levels in all counties where soybeans were grown, and by almost 70 million bushels with uniform improvement to pH 5.2. These estimates are based on many simplifying assumptions and are subject to several important sources of uncertainty explored in this study. The calculated changes are small in comparison with effects from other natural and anthropogenic stresses.

    Changes in NADP-isocitrate dehydrogenase isoenzyme levels in Acinetobacter calcoaceticus in response to acetate (1986)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 35 (1986), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Abstract During adaptation of Acinetobacter calcoaceticus to growth on acetate the specific activity of NADP-isocitrate dehydrogenase increased. This response is unique, as in other bacteria grown under the same conditions the activity of the enzyme decreases as a result of covalent phosphorylation. Moreover, A. calcoaceticus is also unusual in containing two distinct isoenzymes of NADP-isocitrate dehydrogenase. It has here been shown that the adaptation of A. calcoaceticus to acetate is accompanied by an increase in the relative proportion of the larger, allosteric, isoenzyme with a concomitant decrease in the level of the smaller, non-allosteric, isoenzyme.

    On-line estimation of mycelial cell mass concentrations with a computer-interfaced filtration probe (1985)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 27 (1985), S. 729-742 
    Details
    ISSN: 0006-3592
    Keywords: Chemistry ; Biochemistry and Biotechnology
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: This article deals with the design and operation of a filtration probe for estimating cell concentrations in fermentations involving mycelial organisms such as Penicillium chrysogenum. This device, a much improved version of one developed previously, is placed directly into the fermentor and measures the filtration properties of the fermentation broth, which are correlated to the cell concentration. The probe is connected to a computer system which enables on-line estimation of the cell concentration. Fiber-optic light guides are used in combination with a pair of light sources and receivers to detect the relative position of the filter-cake-fermentation-broth interface. The lower sensor in the filtration tube enables reliable estimation of cell mass upto about 20 g/L (dry wt), while the upper sensor yields useful measurement of the filtration properties upto a concentration of about 40 g/L (dry wt) and appears to have the potential to go even higher. Major advantages of this probe system are the ease of measurement and the on-line ability to measure very frequently, due to its nondestructive mode of operation. Thus, the probe obviates the need for manual sampling and reduces the risk of contaminating the culture. But, more significantly, it enables one to implement on-line schemes including feedback control.

    Experimental adaptive on-line optimization of cellular productivity of a continuous bakers' yeast culture (1985)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 27 (1985), S. 1236-1245

    Notes: An adaptive on-line optimization method that utilizes dynamic model identification has been applied to maximize the cellular productivity of a continuous bakers' yeast culture. Experiments were conducted on a sophisticated computerized fermentation system. Experimental results show that the adaptive on-line optimization method requires very little a priori information, is easy to implement, converges quickly, adapts to changes in the process, and is stable even when operational difficulties are encountered.

    Analysis of continuous cultures of recombinant methylotrophs (1987)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Static and dynamic characteristics of continuous cultures of recombinant methylotrophs, which are designed to improve the selectivity of plasmid-bearing cells and the plasmid stability, are investigated in detail. Operational regions in which coexistence (survival of plasmid-bearing and plasmid-free cells) operation is feasible have been identified in the entire space of kinetic parameters and operating variables. The stability characteristics of each steady state are examined. The existence of oscillatory states around the coexistence steady state is investigated using the dynamic (Hopf) bifurcation analysis. For proper startup of the continuous culture operation, it is critical to identify the sets of initial conditions, if any, which lead to transients that ultimately result in washout of plasmid-bearing cells and avoid such conditions. For the numerical illustrations presented, the coexistence steady state happens to be locally stable over much of its region of existence, particular for the operating conditions corresponding to maximum productivity.

    Experimental multivariable adaptive optimization of the steady-state cellular productivity of a continuous baker's yeast culture (1989)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 33 (1989), S. 16-25 
    Details

    Notes: A multivariable adaptive optimization algorithm that uses transient data to improve the optimization speed was successfully implemented on-line to maximize the steady-state cellular productivity of a continuous culture of baker's yeast. The algorithm was shown to be stable even during periods of oscillatory growth and was able to reoptimize the culture when planned disturbances were introduced. Although adaptive tuning of the forgetting factor improved the performance, further refinements in the adaptive forgetting factor algorithm are necessary for completely satisfactory results.
