This study aims to describe a new universal method to identify the relative three-dimensional directions of visual, pupillary, and optical axes of the eye and the angles between them using topography elevation data. The method was validated in a large clinical cohort, and ethnical differences were recorded. Topography elevation data were collected from 1992 normal eyes of 966 healthy participants in Italy, Brazil, and China. The three main axes were defined as follows: optical axis (OA) was defined as the optimal path of light that passes through the ocular system without refraction. The pupillary axis (PA) line was defined using X and Y coordinates of the pupil centre with the chamber depth, in addition to the centre of a sphere fitted to the central 3 mm diameter of the cornea. The visual axis (VA) was taken by its best approximation, the coaxially sighted corneal light reflex. The alpha angle was measured between the VA and OA, and the kappa angle between the VA and PA. The average values of kappa and alpha angles were 3.41 ± 2.84 and 6.04 ± 2.43 in the Italian population, 2.6 ± 1.53 and 5.87 ± 2.3 in the Brazilian population, and 2.09 ± 1.22 and 3.85 ± 1.48 in the Chinese population.

Abstract The main objective of our work is to measure 238U, 232Th, 222Rn and 220Rn in different table oil samples using a method based on the use of two types of solid nuclear track detectors: CR- 39 and LR-115 II in order to determine the doses of radiation received by the individuals following ingestion of the samples of table oil studied. Indeed, we have developed an original method based on the determination of the detection efficiencies of CR-39 and LR-115 II solid nuclear track detectors for alpha particles emitted from the uranium 238 and thorium 232 series to evaluate 238U, 232Th, 222Rn and 220Rn concentrations in different table oil samples. We were able to determine doses of radiation due to 238U, 232Th and 222Rn received by individuals of the Moroccan, French, Italy, Spain and Tunisia populations following the ingestion of table oil. The effective doses committed due to 238U, 232Th, and 222Rn following the ingestion of the table oil by the consumers were determined. The maximum total committed effective dose was found equal to (10±0.7) µSv·y−1 of the Moroccan population, (11.6±0.7) µSv·y−1 of the French population, (10.3±0.7) µSv.y−1 of the Italian population, (10.4±0.5) µSv·y−1 of the Spanish population and (10.5±0.7) µSv·y−1 of the Tunisian population is much lower than the average dose given by the United Nations Scientific Committee on the Effects of Atomic Radiation [1] for ingestion (0.2 to 0.8 mSv·y−1). The results obtained using our method are in very good agreement with those obtained using the model of the International Commission on Radiological Protection

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.

Better Than

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.
