The article reflects the scientific fate of the main genre model – the “questionnaire of the speech genre” of T. V. Shmeleva. The author discusses the reasons for the high demand for the “questionnaire” in genre studies: the parameters of the “questionnaire” affect the most important aspects, the “pain points” of the genre; the formal simplicity and consistency of the “questionnaire”. Along with the advantages and achievements (the article gives their brief description), the author points to a few critical issues concerning the “questionnaire”: the lack of items of the “questionnaire” (the juxtaposition of primary and secondary speech genres, direct and indirect speech genres, speech and rhetorical genres, cultural characteristics of speech genres, etc. are not presented in it) and its crucial points which are not commonly recognized, i.e. the ranking points of the “questionnaire”. In relation to modern genre studies, the article deals with the items that either should be or can be, or have already been added to the “questionnaire”, as well as the theoretical justification of their relations, which, according to the author of the article, will allow to clarify some other items of the “questionnaire”. The emphasis is on those points that are less spelled out in the “canonical” “questionnaire”, but that should be used for a more adequate study of genres (especially new ones), and are already actually used. The discussion focuses on the following points: typological, including the stadial-typological and historical-etymological, features of speech genres; determination of the place of the genre in the structural-hierarchical typology; cultural, linguistic and linguocultural characteristics of speech genres; characteristics of the communicative concept, through which the genre is presented and interpreted, and its components; the ability of the genre to form its variants; corpus and quantitative characteristics of speech genre; online genres.

The intensity of diseases and pests was determined in LLP "Kazakh Research Institute of Plant Protection and Quarantine named after Zhazken Zhiembayev" in the test center of phytosanitary laboratory analysis for phytopathological and entomological examination. As a result of the analysis of entomological examination on the leaves of raspberries were found pests of the plant. No pests or nematodes were found in soil samples. On the basis of the symptoms of the disease and phytopathological analyses, it was found that the presented samples of raspberries are parasitic with purple spot, the causative agent of Didymella applanala, as well as secondarily inhabited by fungi of the genera Fuzarium, Aspergillius, Alternaria, Penicillium, Mucor. Classical phytopathological methods were used for the phytopathological diagnosis of raspberry disease. Determination of fungal and bacterial microflora was carried out on morphological and cultural characteristics of the colony of fungi and bacteria isolated in pure culture.

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.

Using the new reductions of the IUE light curves by Sonneborn et al. (1997) and an extensive set of HST images of SN 1987A we have repeated and improved Panagia et al. (1991) analysis to obtain a better determination of the distance to the supernova. In this way we have derived an absolute size of the ringRabs= (6.23 ± 0.08) x 1017cm and an angular sizeR″ = 808 ± 17 mas, which give a distance to the supernovad(SN1987A) = 51.4 ± 1.2 kpc and a distance modulusm–M(SN1987A) = 18.55 ± 0.05. Allowing for a displacement of SN 1987A position relative to the LMC center, the distance to the barycenter of the Large Magellanic Cloud is also estimated to bed(LMC) = 52.0±1.3 kpc, which corresponds to a distance modulus ofm–M(LMC) = 18.58±0.05.

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.

AbstractPrecise measurements of heliographic position of solar filaments were used for determination of the proper motion of solar filaments on the time-scale of days. The filaments have a tendency to make a shaking or waving of the external structure and to make a general movement of whole filament body, coinciding with the transport of the magnetic flux in the photosphere. The velocity scatter of individual measured points is about one order higher than the accuracy of measurements.

AbstractObservations of artificial earth satellites provide a means of establishing an.origin, orientation, scale and control points for a coordinate system. Neither existing data nor future data are likely to provide significant information on the .001 angle between the axis of angular momentum and axis of rotation. Existing data have provided data to about .01 accuracy on the pole position and to possibly a meter on the origin of the system and for control points. The longitude origin is essentially arbitrary. While these accuracies permit acquisition of useful data on tides and polar motion through dynamio analyses, they are inadequate for determination of crustal motion or significant improvement in polar motion. The limitations arise from gravity, drag and radiation forces on the satellites as well as from instrument errors. Improvements in laser equipment and the launch of the dense LAGEOS satellite in an orbit high enough to suppress significant gravity and drag errors will permit determination of crustal motion and more accurate, higher frequency, polar motion. However, the reference frame for the results is likely to be an average reference frame defined by the observing stations, resulting in significant corrections to be determined for effects of changes in station configuration and data losses.
