The author was led to examine the sun pictures taken by the Kew Photoheliograph, with the view of ascertaining if any connection exists between the behaviour of sun spots and planetary configurations.It was found, that when any portion of the sun's disc recedes by virtue of rotation from the neighbourhood of Venus, it acquires a tendency to break out into spots, and, on the other hand, when such approaches Venus, there is a tendency towards the healing up of spots. Carrington's observations were then discussed, which seem to show that, on the whole, the sun's surface is fullest of spots when Jupiter is furthest from our luminary, and freest from spots when he is nearest.

The two most recent theories dealing with the physical constitution of the sun are due to M. Faye and to Messrs. De la Rue, Balfour Stewart, and Loewy. The chief point of difference in these two theories is the explanation given by each of the phenomena of sun-spots. Thus, according to M. Faye, the interior of the sun is a nebulous gaseous mass of feeble radiating-power, at a temperature of dissociation; the photosphere is, on the other hand, of a high radiating-power, and at a temperature sufficiently low to permit of chemical action. In a sunspot we see the interior nebulous mass through an opening in the photosphere, caused by an upward current, and the sun-spot is black, by reason of the feeble radiating-power of the nebulous mass.

In this paper the sun-pictures taken by the Kew photoheliograph for the years 1862 and 1863 are discussed; the heliographic latitude and longitude of every spot is given, and the area of each group on each day when it was observed is expressed in millionth parts of the sun’s whole hemisphereal area. The Kew photoheliograph itself, as well as the instrument invented by Mr. De la Rue for measuring sun-pictures, have been already described by Mr. De la Rue in the Bakerian Lecture for 1862. These descriptions are not therefore repeated in this paper; but, on the other hand, the method by which the heliographic position of spots is deduced from the measurements made is given at considerable length. The results of succeeding years, and their final discussion with reference to the sun’s elements, will be published hereafter.

The president calls attention to the large and increasing membership of Commission 12 and the policy of concentrating in it all matters relating to the sun. The result makes it comparable in breadth of field and in membership to the former Union for Co-operation in Solar Research. The main point in favour of this policy is the increased interest in the meetings of the Commission and the larger number of individuals reached compared with the meetings of small committees. One recalls the general sessions of the Solar Union in which each one present felt himself a part of the Union and in real touch with the work of different sections and after the discussions went away with fuller knowledge of what it was all about. This was a valuable result not attained to the same degree from the general sessions of the present Union, but in a measure it does follow from the meetings of the Solar Physics Committee. On the other hand the question may be raised whether or not the merging of independent commissions into subdivisions of a large commission lessens their interest to an extent not balanced by the advantages. If the present policy holds, it seems to the president that a re-organisation of Commission 12 is advisable by which more responsibility is laid upon the directors of centres. The basis of membership in the Commission may well be considered and recommendations formulated for transmission to the Executive Committee.

It is known that the Greeks found the means of time-reckoning when they began to observe and to record the rising and setting of the stars. Such recording had already been made in Babylonia and Egypt and taken up in Greece (and further developed) by Hesiod, Democritus, Eudoxus, and Ptolemy. Our knowledge of what they achieved was based until the end of the nineteenth century on the calendars of Geminus, Ptolemy, Aetius Amidenus, the Quintilii, Clodius Tuscus (and on some occasional references in other writers). In recent decades further examples have been found in astrological manuscripts and in papyri, amongst which the Calendar of Antiochus and that of the Pap. Hibeh 27 are the most prominent. Professor Rehm in his admirable Parapegmastudien has recently shown how much can be learnt from the simple entries in calendars about time-reckoning, astronomy, and, in general, about the cosmic system of a nation or a period. Religious entries on the other hand (which are of great importance for the origin and development of festivals) are less frequent—we find in the Hibeh Papyrus a number of local Egyptian festivals and in the Calendar of Antiochus two festivals of the Sun and a festival of the Nile.

This study is intended to find out the meaning behind verbal and non-verbal communication in product placement in Korean drama, Descendant of the Sun. Conducting this study, I apply the theory process of signification proposed by Saussure (1974) and Chandler (2007) and Kinesics proposed by Birdwhistell (1970). The subject of this study is verbal and non-verbal communication in product placement in Korean drama Descendants of the Sun. The data was collected through video media from AsianNet.com and several resources. The findings of this study showed that verbal and non-verbal communication in drama DOTS creates the meaningful messages to its viewers. The findings also show that almost everything in the product placement, possibly have communicative purpose to its viewers. This study also found that non-verbal expressions are generally used to support the verbal communication and it is central to interpersonal relations because non-verbal cues are generally important in emotional communication. On the other hand, verbal communication is central to official or formal relationship. Moreover, the verbal and non-verbal communication in product placement mainly have communicative purpose to encourage, inform, persuade even change the opinion to its viewers to buy, use and know more about the products and services.

While at night almost all optical effects of the atmosphere have to be investigated by using stellar images, the solar observer has at his disposal the solar disk of about half a degree in diameter, covered all over with low contrast details of about 1″, the granules, and confined to the sky by a sharp limb. This enables him to observe all effects occuring within the area of the Sun simultaneously, to follow even the propagation of certain atmospheric effects across the disk. On the other hand he has only the Sun and cannot — as night astronomers might do — extend his observations to all directions in the sky.

In spite of the importance of knowing the color of the Sun on a modern standard photo-electric system, only two efforts have been made during recent times to measure this quantity. These are by Stebbins and Kron (1) who measured the Sun on the six-color system of Stebbins and Whitford, and by Louis Gallouët (2) who measured the Sun on theUBVsystem of Johnson and Morgan. Stebbins and Kron compared the light from the Sun after it had been dimmed with a special “reducing” device with the light from a tungsten ribbon filament standard lamp, which, in turn, had been compared with the light of distant stars. Gallouët, on the other hand, measured both the Sun and stars by means of an extremely ingenious optical instrument that acted as a light gatherer when used on the distant stars, and as a light reducer when used in its inverted optical sense on the Sun. Gallouët also measured the magnitude of the Sun, as well as the color and magnitude of the full Moon.

1. Hitherto in our reductions we have summed up the spotted areas of the various groups occurring on the sun’s surface on any day, and have regarded their sum as a representation of the spot-activity for that day. It has occurred to us to see what result we should obtain by taking instead for each day the excess of the spotted area in the one solar hemisphere above that in the other. 2. On adopting this method, it soon became evident that during periods of great disturbance there is a tendency in spots to change alternately from the north or positive to the south or negative hemisphere, and vice versâ , the period of such change being about 25 days. When, on the other hand, the solar disturbance is inconsiderable, the spots do not present any such systematic oscillation.

Since our Association was founded more than forty years ago, many things have happened under the head of political science. Men and women as political animals have supplied scholars with new data sufficient in volume and variety to satisfy the most exacting minds in the profession. At our annual sessions, numerous learned papers have been read and discussed. At our universities, new courses of studies have flowered luxuriantly. From the workshops of the guild, books and articles have poured forth in a copious stream. Several of our members have achieved distinction, indeed renown, in the public services; while, as far as I can discover, none has been sent to prison under the presidential decree of 1947 against that type of lawful dissent stigmatized as subversive activity. As if in testimony to our good works, it should be added that the amount of money now laid out per annum for political science is many times the sum expended long ago when we were young.It might seem, then, an act of temerity even to suggest that anything under the sun has been neglected or less than perfectly disposed of in our golden age, our best of promised lands. Undoubtedly it is temerarious for one like myself, with eyes full of beams, to raise questions about stray motes in the eyes of members who may be properly satisfied with their accomplishments. Yet, on the other hand, there is some authority in our tradition and methodology, no less than in the practice of free enterprise, for occasional surveys or audits designed to find out whether in fact our liabilities are fully covered by assets, fixed and liquid.

Resumo: This article presents a comparative analysis of the novels O cortiço (1890), by the Brazilian writer Aluísio Azevedo, and Emigrantes (1928), by the Portuguese author Ferreira de Castro. The goal is to identify how Portuguese people who emigrated to Brazil were represented in characters of these works. It was found that, in O cortiço, migration appears as degeneration caused by the hostile social and natural environment of Brazil, according to the premises of the naturalist aesthetics. Under the influence of the sun, poverty and the Brazilian human landscape, the Portuguese people either get rich by stealing and exploiting labor, including slavery, or undergo a life of addiction. On the other hand, in Emigrantes, this migratory flow appears as a mirage, because the possibility of enrichment in America fades away in the confrontation with the concrete experience of the characters. In the study, contributions from critics Antonio Cândido, Eduardo Lourenço and Miguel Torga are mobilized, as well as statistics that contextualize Portuguese immigration in Brazil.Palavras-chave: migração portuguesa no Brasil; Aluísio Azevedo; romance naturalista; Ferreira de Castro; Realismo; literatura comparada.Abstract: This article presents a comparative analysis of the novels O cortiço (1890), by the Brazilian writer Aluísio Azevedo, and Emigrantes (1928), by the Portuguese author Ferreira de Castro.
