At Dr Murray's request, I have during the past winter continued the investigation of Messrs Irvine and Young on the solubility of carbonate of lime in its different forms in sea water (the results of which they submitted to this Society in May 1888); and the following notes of the work done and the results obtained by me, under Mr Irvine's guidance, in the laboratory of the Marine Station, Granton, may be of interest.

Text from page 3: This paper is based on work done during the summer of 1915, while the writer was a member of a field party, engaged in geological work in the vicinity of Breckenridge, Colorado. Through the kindness of Mr. R. M. Henderson, manager of the Wellington Mines Company's property, permission was secured to examine the underground workings of the Wellington mine, the most important zinc-lead mine in the Breckenridge district. Plans showing the location of the principal drifts and stopes were furnished by Mr. Henderson, and, with these maps as guides, the writer made quite a thorough survey of the workings, determining, as far as possible, the geology and mineralogy of the mine. Many specimens of the country rock and the minerals were secured, and intensive study was made of them in the laboratory during the past winter.

The method developed over the past decade in northern Japan to culture phyllosoma larvae of five species of principally cool-temperate spiny lobsters combines the features of upwelling water, co- cultured microalgae, and use of mussel gonad as food. The feeding behaviour of the phyllosomas shows that they are primarily predators with the pereiopods and secondarily plankton feeders with the maxillipeds and maxillae. Recent work has shown that contamination of culture water by microorganisms such as the fouling protozoans Vorticellaspp. can greatly reduce phyllosoma survival. The significance of co-cultures of microalgae in maintaining water quality is not yet fully understood. Newly hatched lavae of sailfin sandfish (Arctoscopus japonicus) is an excellent food for late-stage phyllosomas of Jasus verreauxi. About 5% of J. verreauxi phyllosomas metamorphosed into pueruli. Mortality during the puerulus stage was reduced by increasing the capacity of the culture tanks from 30 L to 100 L. A single Palinurus elephas phyllosoma raised in co-culture with diatoms and fed mussel gonad and A. japonicus larvae metamorphosed into a puerulus in 65 days after seven moults.

Considering all the work done on vowel system typology and universals in the past half-century (Trubetzkoy 1929, 1939; Hockett Sedlak 1969; Crothers 1978), my title may seem rather arrogant. There are after all theories of vocalic organisation about, or at least models and taxonomies; there are even attempts to explain why certain implicational universals seem to hold (from Jakobson's [laws of solidarity] (1968) to the more sophisticated treatments in Liljencrants & Lindblom 1972; Kim 1973; etc.).

Preface to Preliminary Beports. The Preliminary Beports have been prepared at the request of Professor Wyville Thomson. They have been compiled during the past three weeks from notes taken daily during the past three years. In only a few cases has it been possible to refer to the objects remarked upon, they haviug been sent home for greater safety, or packed away beyond reach. When specimens taken early in the cruise can be placed side by side and compared with tfie more recent revelations of the trawl, dredge, or soundingtube, many of the statements herein made may require to be modified. Beports on three years’ wrork, prepared under the disadvantages above mentioned, must necessarily be very incomplete; and indulgence may be asked till the final Eeport can be issued.

Taking a historical perspective, we provide a brief overview of the first-principles modeling of ferroelectric perovskite oxides over the past 30 years. We emphasize how the work done by a relatively small community on the fundamental understanding of ferroelectricity and related phenomena has been at the origin of consecutive theoretical breakthroughs, with an impact going often well beyond the limit of the ferroelectric community. In this context, we first review key theoretical advances such as the modern theory of polarization, the computation of functional properties as energy derivatives, the explicit treatment of finite fields, or the advent of second-principles methods to extend the length and timescale of the simulations. We then discuss how these have revolutionized our understanding of ferroelectricity and related phenomena in this technologically important class of compounds. Expected final online publication date for the Annual Review of Condensed Matter Physics, Volume 13 is March 2022.

1. The following paper is divided into three sections, containing three distinct yet intimately connected investigations. The two first on the Polarizability and Depolarization of Heat have arisen immediately out of the train of investigation contained in my two former papers, and the researches of others to which they gave rise. The third is on the Refrangibility of Heat, a point of the highest importance for theory.2. The experiments on which these investigations are based have been performed almost exclusively during the past winter. Part of the experiments on Depolarization were, however, made in the winter 1836-7. The mode adopted for trying Refractive Indices I had long ago contemplated. It was not, however, put in practice until January last.

In the proposed review of scientific research, set out in 2 books, in a chronological framework: 1917–1977. and 1977–1993, the analysis of social technologies associated with the forms of organization of councils as state authorities, its political basis in the USSR / Russia, their capabilities, which had transformations during the periods of their formation and development, as well as other types – executive committees, revolutionary committees (revolutionary committees). The process of the emergence of the system of these authorities on the territory of the Kamchatka province / region is considered. The attitude of the researcher to the study of aspects of the topic is shown. His knowledge of both the essence of the existing assessments of their role, and the contribution to the development of the system itself. The content of directions for improving the management and regulation of social processes is analyzed. Attention is drawn to the direction of solutions to the problems of strengthening statehood, achieving effective activity of structural units, from lower to higher authorities. The author identified about 2000 portraits of political and public figures, representatives of this system in the Kamchatka region, disclosed the forms and methods of their work in different areas of management, development of the community of peoples on the territory of the multinational region. Materials and methods. In the writing of a review, the appeal to such methods as historical-genetic, historical-comparative, historical-typological, which allows, in aggregate, to trace the differences of the process, events that reflect the essence of the phenomenon that characterize the interaction, prevails. Along with this, a comparison of the processes of development of society and the management system at different stages of the period under study in 1917–1977, the military situation on the eve of the war, the war period of 1941–1945, post-war reconstruction, 1977–1993, the degree of generalization by the author of the material presented, revealing by him the essence of the transformations that took place. It is also obvious that there was every reason for attracting the prosopographic method of research, which allows not only to fully cognize the person (who represents power), but also to show the background of events. As for the materials directly, http://www.hist-edu.ru Историческая и социально-образовательная мысль. Toм 13 №2, 2021 Historical and Social-Educational Idea. Volume 13 #2, 2021 295 the researcher evaluates those that are used by him in the narrative – "living sources" (archival documents, press, memoirs) Due to the lack of analysis of the historiography of the problem under study, it is possible to present not only an assessment of the work done by the author. They mention, with rare exceptions, for example, the works of the famous writer of the Kamchatka Territory A.A. Smyshlyaev, as well as a collection of documents. The author identifies in the course of his work a large corps of workers' deputies employed in the past or in modern conditions in the work of government bodies (since 1917), of whom about 2 thousand people are mentioned.

This chapter identifies changes that the printing industry has undergone during the past 25 years as a result of the digital revolution. It also provides a brief historical perspective of the printing industry and how it has evolved. It is undeniable that the computer has had an impact on the development of print media and today it is rare to find any prepress work done without the use of some digital technology. The workflow of a traditional printed piece is described from start to finish and is compared to a more modern digital workflow to familiarize readers with the processes and contrast the old with the new techniques. This chapter will identify common problems that occur in the preparation of print media using digital technologies. In particular, it will explore a variety of problems and solutions related to the use of digital prepress as well as identifying new innovations intended to improve prepress operations in the future.
