1. Pneumococci were obtained at one time or another from the nasal passages or throats of 80 per cent of 105 adults and children studied. In adults, they were obtained more frequently from the throat; in children, as often from the nasal passages as from the throat. 2. Of 500 pneumococcus strains studied, 97 per cent proved to be serologically specific. They formed smooth colonies and were for the most part avirulent for mice. Types I and II were obtained from one and two individuals respectively on one occasion only. Type III was obtained from nine individuals; Type XIII from nine individuals; Type XVI and Type XVIII from three individuals, for varying periods in each case. Atypical pneumococci were secured from 13 persons on single and scattered occasions. They varied in colony morphology, did not kill mice, or agglutinate in saline, but flocculated in all types of antipneumococcus sera employed and over a wide pH range in acid buffers. Their occurrence was apparently not associated with any type-transformation or virulence-enhancement process in vivo. 3. Strains of pneumococcus obtained on successive cultures from a given carrier were, with rare exceptions, of the same serological type and were similar in colony morphology, virulence for mice, and other tested biological characteristics. 4. Pneumococci of Types I and II were obtained under conditions suggestive that they lacked a capacity to spread readily; pneumococci of Types III and XIII, on the other hand, were obtained under conditions suggestive that they were spreading from person to person. 5. The persons studied differed consistently with respect to the occurrence of pneumococci. Some were pneumococcus-free, some were transient carriers, some periodic, and some chronic carriers. Data are given which suggest that the differences were due to variations in host resistance. 6. The incidence of pneumococci in all individuals studied underwent a seasonal variation paralleling that of coryza and sore throats in the same persons.

The biomorphological analysis of the flora of eighteen ancient settlements of the Lower Dnipro as a potential "islands" of steppe biodiversity has been introducing. Based on the most commonly used linear systems of life forms by K. Ranquier and by V.M Golubev there have been presented the results of the analysis of biomorphs. In addition to the main biomorph, the following characteristics were taken into account: multiplicity of fruiting, main types of vegetation, type of underground shoots, type of aboveground shoots, type of root system. Domination in the general spectrum of life forms of the studied flora of herbaceous plants was determined (455 species or 86.8 % of the total number), among which perennials made up the majority (259 species or 49.4 %). The second and third groups are occupied by annuals (148 species or 28.2 % of the total) and biannuals (48 species or 9.2 % of the total), respectively. According to the multiplicity of fruiting, the participation of polycarpics (328 species; 62.6 %) is significant. However, it should be noted, that the high share of herbaceous monocarpics (196 species; 37.4 %) can be explained by the invasion of adventitious species from neighboring agricultural fields and existing settlements. By type of vegetation, summer-green species represent almost half of the total list of flora (231 species), while that of the group of summer and winter green plants was represented by 168 species or 32 %. By type of aboveground shoots, the predominance is given to semi-rosette species (276 species; 52.7 %), and by type of underground shoots - to caudex (201 species; 38.4 %) and plants without rhizomes (196; 37.4 %). Our study confirmed that biomorphological structure of the flora of ancient settlements are quite typical for the flora of the steppe zone and the flora of the Holarctic in general, as evidenced by the predominance in the respective spectra of perennial grasses, hemicryptophytes, polycarpics, plants with caudex type of underground shoots and rod type. Transformation of the zonal spectrum as a result of anthropogenic impact is manifested in a significant percentage of trees, annuals, monocarpics and species of rhizome structure.

AbstractIn a recent paper, Miller derived a Kummer-type transformation for the generalised hypergeometric function pFp(x) when pairs of parameters differ by unity, by means of a reduction formula for a certain Kampé de Fériet function. An alternative and simpler derivation of this transformation is obtained here by application of the well-known Kummer transformation for the confluent hypergeometric function corresponding to p = 1.

ABSTRACT Reductions to 2, 5, and 42% of the wild-type transformation efficiency were found when Agrobacterium mutants carrying transposon insertions in virD2, virC2, and virE2, respectively, were used to transform Aspergillus awamori. The structures of the T-DNAs integrated into the host genome by these mutants were analyzed by Southern and sequence analyses. The T-DNAs of transformants obtained with the virE2 mutant had left-border truncations, whereas those obtained with the virD2 mutant had truncated right ends. From this analysis, it was concluded that the virulence proteins VirD2 and VirE2 are required for full-length T-DNA integration and that these proteins play a role in protecting the right and left T-DNA borders, respectively. Multicopy and truncated T-DNA structures were detected in the majority of the transformants obtained with the virC2 mutant, indicating that VirC2 plays a role in correct T-DNA processing and is required for single-copy T-DNA integration.
