The three charts which were exhibited, showing, by isobarometric lines, the mean atmospheric pressure over the globe, during January, July, and the year, were constructed from observations made at 358 places thus distributed over the earth,—167 in Europe; 51 in Asia; 22 in Africa and adjoining islands; 35 in South America, West Indian Islands, and Atlantic; 63 in North America; and 20 in Australasia and Antarctic Ocean. Of the European stations, 12 are in Scotland, 14 in England, 27 in Austria, 12 in Italy, 10 in France, 10 in the Netherlands, 9 in Norway, and 57 in the Russian empire, &c. The list might have been largely increased; thus a larger number might have been given from the 80 Scottish stations; but the 12 given were judged sufficient to represent the mean atmospheric pressure of this country.

In Part I., read 16th March 1868, in which was discussed the Mean Pressure of the Atmosphere over the Globe for July, January, and the year, the method by which the Isobaric Charts were constructed was detailed at length. Since March 1868, valuable additional information has been obtained from Australia, New Zealand, Tasmania, Africa, South America, the west coast of North America, Iceland, and from a few isolated stations in Europe and Asia. The period for the British Islands has been extended so as to include the eleven years from 1857 to 1867.

First use of triangulation in "measurements of degrees" by Willebrord Snel in the Netherlands and Karl F. Tenner in the Russian empire are briefly described in connection with their "round-number" anniversaries in 2017 (quadricentennial and bicentennial respectively). A special emphasis is placed on significance of the Tenner triangulation chains which made up the largest segment of the "Russian arc" ("Struve arc").

The static mechanics of the hypotonic pharynx were endoscopically evaluated in nine sleeping patients with obstructive sleep apnea, having a primary narrowing only at the velopharynx. The velopharynx closed completely at a mean pressure of 0.18 +/- 1.21 cmH2O, and the mean half-dilation pressure was 1.93 cmH2O above closing pressure. The dependence of area on pressure was distinctly curvilinear, being steep near closing pressure and asymptotically approaching maximum area (mean = 1.32 cm2). The data for each patient were satisfactorily fitted by an exponential function (mean R2 = 0.98), and a single exponential relationship usefully represented the dependence of relative area on pressure above closing pressure for the population (R2 = 0.85). During the test inspiration, flow limitation was consistently observed when mask pressure exceeded closing pressure by 0.5–3.0 cmH2O. In summary, the static mechanics of the hypotonic velopharynx of patients with obstructive sleep apnea can be described by an exponential pressure-area relationship, with a closing pressure near atmospheric pressure and a high compliance in the range of airway pressure 0–3 cmH2O above closing pressure.

We know the mass of the Moon very well from the amount it pulls the Earth about in the course of a month; this is measured by the resulting apparent displacements of an asteroid when it is near us. Combining this with the radius shows that the mean density is close to 3.33 g/cm 3 . The velocities of earthquake waves at depths of 30 km or so are too high for common surface rocks but agree with dunite, a rock composed mainly of olivine (Mg, Fe II ) 2 SiO 4 . This has a density of about 3.27 at ordinary pressures. The veloci­ties increase with depth, the rate of increase being apparently a maximum at depth about 0.055 R in Europe and 0.075 R in Japan. It appeared at one time that there was a discontinuity in the velocities at that depth, corresponding to a transition of olivine from a rhombic to a cubic form under pressure. It now seems that the transition, though rapid, is continuous, presumably owing to impurities, but the main point is that the facts are explained by a change of state, and that the pressure at the relevant depth is reached nowhere in the Moon, on account of its smaller size. There will, however, be some compression, and we can work out how much it would be if the Moon is made of a single material. It turns out that the actual mean density of the Moon would be matched if the density at atmospheric pressure is 3.27—just agreeing with the specimen of dunite originally used for comparison. The density at the centre would be 3.41. Thus for most purposes the Moon can be treated as of uniform density. With a few small corrections the ratio 3 C /2 Ma 2 would be 0.5956 ± 0.0010, as against 0.6 for a homogeneous body. To make it appreciably less would require a much greater thickness of lighter surface rocks than in the Earth.

Charts, showing by Isobaric Lines the mean pressure of the atmosphere over the globe during the months of the year, may be justly regarded as furnishing the key to all questions of meteorological inquiry; for without the information conveyed by such charts it is impossible to discuss satisfactorily those questions which relate to prevailing winds, the varying temperature, and the rainfall throughout the year in the different countries of the world. It is to meet this desideratum that the Charts of Mean Atmospheric Pressure of the globe which are given with this paper are offered as the first approximate solution of this great physical problem.Since Part I. was read in March 1868, valuable additional information has been obtained from Australia, New Zealand, Tasmania, Africa, South America, the west coast of North America, Iceland, Norway, and Sweden, and from several isolated stations in different parts of Europe and Asia. The period for the British Islands and a large portion of Europe has been extended so as to include the eleven years from 1857 to 1867.

[Rev. of: Rjéoutski V., Frijhoff W., eds., Language Choice in Enlightenment Europe: Education, Sociability, and Governance, Amsterdam, 2018, 233 pp.] The book under review is an English-language collective monograph called “Language Choice in Enlightenment Europe: Education, Sociability, and Governance”, written by authors from the Netherlands, Italy, Russia, Estonia, and Croatia (edited by Vladislav Rjéoutski and Willem Frijhoff). The subject of the monograph is the language choice in the European countries of the 18th century. This is the sixth book in the Languages and Cultures in History series, and it includes an introduction, eight articles by the international team of authors, and an alphabetical index of names and places mentioned. The Enlightenment was marked in Europe by the gradual abandonment of Latin in education and public administration and its replacement by vernaculars. At the same time, there are peculiarities in every country, particularly in the Russian Empire and Croatia. Archival materials (private letters, memoirs, official questionnaires, statistics) make this book extremely valuable. The authors analyse the linguistic situation in France, the Netherlands, Central Germany, the Estonian Governorate, Croatia, the Hungarian Kingdom, and the Russian Empire. Language choice is discussed at the micro-level (e.g. within one family) as well as at the macro-level (e.g., in education, public administration, among the nobility or clergy). The book will be of great interest to historians, linguists, sociologists, anthropologists, as well as to specialists in international relations.

Abstract The purpose of this research is to analyze the geographical shape of the earth’s face with the 472319 Hahslm patterns in geomorphology. Earth undergoes the process of forming water and soil so that it becomes a continent and an archipelago. The composition of the sea and land is 7:3. The object of this study is the shape of the sea and land on earth and the Quran 13.31. This research was conducted by studying literature from books, journals, electronic media, and earth globes, and world atlases. The methodology used is descriptive-analytical. The method used is reflexivity, similarity, and dynivity with the formula 472319 Hahslm. The result obtained is the process of changing the shape of the earth’s surface towards a pattern of worship by the meaning of the holy book in the form of cutting the earth according to the meaning of the Quran. The Quran formula 13.31 forms an arrangement of 444 in the form of letter number 13, namely 1+3=4, and from 31, namely 3+1=4. The third pattern 4 is obtained from the number of letters hijaiyaj in the word for cutting the earth as many as 13 letters meaning 1 + 3 = 4. The geomorphological reflectivity of the earth resembles the pattern of 444. With the composition of the oceans and lands of 7:3 which has a difference of four from 7-3=4. In the formula, 472319 Hahslm derived from the Quran 15.87 means the Quran in the form of 6438 verses. The second meaning of 4 is obtained from the multiplication of 7 and 2, namely 7x2=14 by taking the first four words of the fourteenth phrase. And the third meaning of 4 from addition is 3+1+9=13 where the root of digit 13 is 1+3=4. The second geography of the earth is at number 4 from the geomorphology of the continents of Asia, Africa, Europe, and Australia which forms a hand pattern of 319. With the tips of small fingers located in parts of countries that have islands located in the eastern to southeastern Asian continents such as parts of Russia, Japan, Korea, China, and the Philippines. Meanwhile, the Southeast Asian region forms the index finger or pattern 1 which has a similarity to the shape of the Indonesian archipelago with the tip being large in Australia and New Zealand. Big finger thumb or pattern 9 has similarities with mainland India, Pakistan, Bangladesh in South Asia. While the Americas have similarities with pattern 7 or V for South America and pattern 2 for North America. Waters and islands are needed in a pandemic that has an economic effect. The conclusion is that the geography of the earth forms 472319 show the earth is worshiping even during the Covid economic era.

The geographical distribution of Smicra differs much from that of Leucospis. Unlike the latter genus, which is spread thinly and somewhat equally over the warm and temperate regions of the earth, Smicra, with very few exceptions, is limited to the New World, where there are some species in North America, many in Mexico and in the West Indies, and great abundance in the tropical parts of South America, and the genus has thus much more influence than Leucospis in regulating, by means of transfer, the increase of other insect tribes.

A tracer element can help distinguish between indoor PM2.5 of outdoor origin and that of indoor origin. PM2.5-associated iron has been proposed as a tracer element of PM2.5 in Beijing. This study aims to examine the effect of particulate iron on tracking indoor PM2.5 of outdoor origin in temporal and spatial scales. From July 2018 to March 2019, we collected 24 pairs of indoor and outdoor PM2.5 samples in Nanjing, China. We calculated a normalized ratio (ratio of indoor/outdoor (I/O) ratio of iron to that of PM2.5). Results show a mean ± SD of the normalized ratio of 1.0 ± 0.38. It suggests that particulate iron tracks PM2.5 well during outdoor-to-indoor transport on average. This tracking performance varies temporally. The mean ± SD of the normalized ratio is 0.79 ± 0.17 from July to December 2018 and 1.2 ± 0.41 in March. The results from studies published in different regions of the world over recent years show a mean normalized ratio of 0.88, 0.67, 1.3 and 0.8 in Asia, Europe, North America and South America, respectively, indicating the spatial heterogeneity of iron’s tracking effect. In comparison, sulphate appears to exhibit a less stable tracking effect than iron.
