The Relationship

To predict the dynamics of landslide processes, it is necessary to have information about the change of factors of man-made and natural influences over time. An important source of such information is instrumental and geodetic monitoring. To choose an effective method and systems of instrumental monitoring, it is necessary to compare the main organizational and technological indicators (duration and labor costs) of variants of such systems. The calculation of the duration and labor costs for measuring work when observing the deformations of landslides can be determined on the basis of existing norms of uniform time norms and prices for survey work or using the trace element method of normalization of labor processes.The article presents a brief analysis of the relationship between the norm of duration of measuring works, on the example of geometric leveling of class II to determine the deposition of deformation control points (marks), determined by the current uniform norms of time and rates for survey work and the duration of the same labor process. microelement method of rationing. The list and structure of works on performance of leveling of the II class, as set of elementary labor actions (operations) so isolated and outlined that the further division is inexpedient is defined. The microelements of the labor process are singled out and their normative duration in hours is determined, obtained on the basis of the experience of operation of measuring instruments during the performance of works on determination of deposition of deformation marks.The coefficient of interrelation between the existing current norms and the actual duration of the labor process, determined by the microelement rationing method for works on geometric leveling of the II class, which allows to distinguish the actual duration of the labor process as a norm, without taking into account the duration of preparatory on holiday. The inconsistency of the current standards of measurement work with modern methods of work, equipment, features of instrumental monitoring, monitoring in compacted buildings and other types of work creates the need to determine the elements of the relationship between existing standards and the actual duration of work in modern construction.

Background: The plant Dryopteris filix-mas has been used traditionally for its uterine-stimulant effects.Aim: The current study is therefore aimed at investigating and determining the effect of the leaves of D. filix-mas on uterine contractility in vitro.Setting: Fresh leaves of D. filix-mas were collected from a river bank in the south-western part of Nigeria.Methods: The leaves of D. filix-mas were cleaned, dried and extracted in methanol. The extract (0.07 µg/mL–21.0 µg/mL) was tested on the isolated mouse uteri in order to determine activity on spontaneous-induced uterine contractions. Subsequently the extract (0.005 mg/mL and 0.05 mg/mL) was tested on oxytocin-induced contraction (0.00017 ng/mL–4.98 ng/mL) in calcium-containing media, submaximal oxytocin-induced contraction (0.116 ng/mL) in calcium-free media and in the presence of high KCl-induced uterine contractions (80 mM). The extract was also subjected to mass spectrometric determination of secondary metabolites.Results: The plant extract inhibited spontaneous-induced contractions with IC50 amplitude = 658.41 ng/mL ± 0.11 ng/mL and IC50 frequency = 175.32 ng/mL ± 0.53 ng/mL. The plant extract inhibited oxytocin-induced and high KCl-induced uterine contractions (p < 0.01 at 0.5 mg/mL). The plant extract had no effect on oxytocin-induced contractions under calcium-free conditions. Secondary metabolites belonging to classes of fatty acids, alkaloids, saponin glycosides, amino acids, limonoids, terpenes and porphyrins were identified.Conclusion: The current study reports an inhibitory effect of the plant on uterine contractility in this study, suggesting possible application as a tocolytic or as a contraceptive, as most contraceptive plants have shown uterine-relaxing effect.

The Galaxy

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.

Sn 1987A

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.
