    Notizen: This paper reports upon the first official application of the estate multiplier method of estimating the wealth distribution to French data. It is based upon a sample of estate duty returns filed during the period September-December 1977. The sampling rate was 5 percent for estates under one million francs, and 100 percent for estates over this level, giving a total of 5031 records. The data available did not permit a breakdown by type of asset. It did, however, permit classification of estates by age, sex, and occupation of decedent. Experiments were conducted using five different sets of mortality multipliers. The set of mortality multipliers judged most appropriate leads to an estimate of aggregate net wealth that is 77 percent of that given in the national balance sheet of the national accounts. Comparison of the distributions of wealth derived in these estimates suggest that the figures are consistent with those found in other countries.

    Notizen: A review of plasmids in Clostridium perfringens is presented. The characterization of the caseinase mediating plasmid pHB101 based upon limited DNase treatment, restriction endonuclease treatment, and agarose gel electrophoresis is described. Antibiotic profiles for the wild type strain and the cured strain were determined. The plasmid pHB101 was non self-transferable. The curing procedure resulted in a stable morphological change from rod to coccoid or bacillary-coccoid shape. A screening of C. perfringens strains showed the general presence of a 9.4 Mdal plasmid which may have been overlooked in the past due to chromosomal DNA masking effects.

    Notizen: An impedance method was developed for the estimation of coliforms in raw and pasteurized milk, heavy cream, and ice cream mix. Impedance detection times (IDTs) in CM, a medium developed for the impedimetric detection of coliforms, were compared to confirmed Violet Red Bile Agar (CVRBA) plate counts. Correlations of 0.91–0.95 between the two methods were obtained for the four dairy products. The line equations of these relationships were similar for all products. An IDT shorter than 9 hr was indicative of coli- form levels 〉10/mL, while an IDT longer than 12 hr was indicative of levels 〈10/mL. The impedhnetric estimation of coliforms provided the same information as CVRBA counts from dairy products, offering a savings in time and labor.

    Notizen: Snack crackers containing 25, 40, 55, and 70% whole-grain triticale flour were prepared. The crackers did not differ in breaking strength or crispness as measured with the Instron Universal Testing Machine. Sensory panelists used the technique of magnitude estimation coupled with word concepts to evaluate the crispness, taste, and overall acceptability of the crackers. Crackers containing 25 and 40% triticale flour tasted better and were more acceptable than were those containing 55 and 70% triticale flour. Panelists did not find differences in crispness. Protein contents of the crackers ranged from 11.78 to 12.97%. It was demonstrated that triticale flour can be used to produce acceptable, increased-protein snack crackers.

    Notizen: The design and operation of a focusing camera for high-resolution macromolecular crystallography with synchrotron radiation (SR) are described. The performance of this service-oriented instrument is evaluated on the basis of five years of use. Standard procedures for data collection, data processing and data reduction have been modified to take unusual features of the SR source into account; the effect of polarization is thoroughly discussed.

    Notizen: Hexagonal crystals of cowpea mosaic virus in space group P6122 (or its enantiomorph) with a = 451 and c = 1038 Å have been analyzed using the synchrotron X-ray source at LURE. Data were collected using an X-ray beam of size 0.18 × 0.22 mm permitting resolution of reflections along the c* direction. The beam was defined using a multiple slit system at both the monochromator and at the collimator. A helium path was used to reduce air scatter as a specimen-to-film distance of 175 mm was employed. Data to 4.3 Å resolution were recorded on each film. The films were processed to 6 Å resolution using the oscillation photograph processing package developed by Rossmann [J. Appl. Cryst. (1979), 12, 225–238] with minor modifications to the normal procedures. One film was processed to 4.3 Å resolution establishing the feasibility of intermediate resolution analysis. Statistical analysis of the processed data showed excellent correlation between symmetry-equivalent reflections. Post refinement of oscillation angles and lattice constants was very stable and led to significantly improved scaling of partially recorded reflections.

    Notizen: Crystallographic data for three different protein crystals (glycogen phosphorylase b to 2 Å resolution, β-lactamase I to 2.5 Å resolution and troponin C to 6 Å resolution) have been recorded using the intense synchrotron radiation beam emitted by the DCI storage ring at LURE and the DORIS storage ring at DESY/EMBL. Reduction in exposure times of approximately 50-fold and an increase in crystal lifetime of at least fivefold are observed when data recorded at LURE are compared with those recorded with a conventional rotating-anode source. These factors have made possible data collection which otherwise would have been impossible. For large crystals of phosphorylase b a greater reduction in exposure time ( × 125) is made possible by the focusing geometry of the synchrotron-monochromator system which allowed irradiation of a larger volume of the crystal (collimator size increased from 0.3 to 1.0 mm) without significant increase in spot overlap on the film. The data processing statistics for phosphorylase b and β-lactamase compare favourably with those from data recorded on a conventional source (improvements in merging R values of between 1 and 4%). For phosphorylase b, but not for β-lactamase or troponin C, significant thermal diffuse scatter is observed on photographs recorded with synchrotron radiation. The possible origin of this phenomenon and its effect on data processing are discussed.

    Notizen: To allay doubt about how to calculate molar extinction eoeffieients from the specific absorption coefficients of protoehlorophyll(ide), dark-grown leaf segments and saponin protochlorophyll(ide) holochrome subunits frotn barley (Hordeum vulgare L.) and cotyledons of cucumber (Cucumis sativus L.) were extracted with acetone without or following prior, brief illumination. Absorbance data and eoeffieients of chlorophyll a were used to derive extinetion eoeffieients of protoehlorophyll(ide); 626 nm (range: 30 to 35 1 mmol-1 cm-1) without recourse to published coefficients c protochlorophyll(ide). These results combined with evaluation of how the origin; coefficients were obtained, argue for using the molecular weight of protochlorophy rather than protochlorophyllide to calculate molar extinction eoeffieients from th specific absorption coefficients.
