EMG-RTs of the biceps brachii muscles were measured using electromyogram (EMG) in elbow flexion and forearm supination on 18 right-and 24 left-handed subjects for four tasks, flexion or supination (symmetrical) and flexion of one and supination of the other side (asymmetrical). For both subject groups, the EMG-RTs of flexion for both hands were not prolonged under asymmetrical tasks, but the EMG-RTs of supination were significantly prolonged on both sides. Comparing the coefficients of determination of the EMG-RTs of flexion to those of supination under four different tasks, those of the preferred hand for symmetrical and asymmetrical motions did not differ, but those of the nonpreferred side for asymmetrical motions were smaller than those for symmetrical motions in both subjects. These observations indicated prolongation of EMG-RT on the asymmetrical task was larger on supination than on flexion. It was suggested that the influence of strong timing constraints was greater on the auxiliary function than on the innate function of the biceps (elbow flexor). The steadiness of motor function of the preferred hand was also discussed in regard to hand preference.

Seismic Models

The article is devoted to increasing the efficiency of well testing in the construction of seismic models of oil and gas objects. We suggest using the adaptive approach, which has been developed by us, to processing and interpretation of well testing data; it will increase the efficiency of management of the processing and interpretation of well testing data. The essence of the approach consists of dividing the process into stages, developing for each stage a multivariate decision scheme, and formal criteria for evaluating the results.A conceptual framework has been developed for the implementation of the proposed approach as applied to the processing and interpretation of well testing data in order to construct seismic models of terrigenous deposits in Western Siberia. We propose formalized criteria for assessing the quality of processing results of well testing data, modeling of well testing curves, and determination of petro-physical parameters. The results obtained are illustrated on practical data on oil fields in Western Siberia.

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.

The Future

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).
