The present catalogue of Anthomyiidae attempts to list all species (173) described or recorded from mainland China (165) and Taiwan (8) that for various reasons are not treated in "Flies of China" from 1998. The catalogue further lists Chinese species that are presently standing in new generic combinations compared to those of "Flies of China", species that have changed name because of synonymy...
The subject of the article is image plague (specifically — cholera) that struck Russia in 1830, which was presented two poems by a graphomaniac poet Dmitry Khvostov (1757–1835). aim research to discuss detail poetic epidemic Cholera 1830 and July Petropolis. portayal cholera Russia’s largest metropolises focuses not only on plague’s daunting form effect, but also strategies combating it. uses d...
We present the first results of an ALMA spectral survey of strong absorption lines for common interstellar species in the z = 0.89 molecular absorber toward the lensed blazar PKS 1830−211. The dataset brings essential information on the structure and composition of the absorbing gas in the foreground galaxy. In particular, we find absorption over large velocity intervals ( 100 km s−1) toward bo...
This paper argues that our modern concept of biological heredity was first clearly introduced in a theoretical and practical setting by the generation of French physicians that were active between 1810 and 1830. It describes how from a traditional focus on hereditary transmission of disease, influential French medical men like Esquirol, Fodéré, Piorry, Lévy, moved towards considering heredity a...
This paper presents data from the BIMA interferometer showing spatially resolved absorption spectra of the gravitationally lensed quasar PKS 1830-211. High-resolution (1.2 km s) spectra were taken in two spectral windows centered on the redshifted frequencies of the HCO(2 ← 1) and HCN(2 ← 1) molecular transitions. There is no molecular absorption in the northeast image but the southwest image r...
The order Billingsellida comprises brachiopods with laminar and fibrous shells, however, the data on their microstructure are scanty and the taxonomic value of differences in their shell structure is uncertain. The shell structure of clitambonitidine Antigonambonites planus was found to be laminar, not fibrous as previously considered; possibly this shows that it belongs to the suborder Billing...
Recent radio VLBI observations of the complex gravitationally lensed system PKS1830-211 have thrown up some questions with regard to the processes occuring at the heart of the blazar source at a redshift of 2.51, which is viewed almost straight down the jet axis. This work links, by a model of a helical jet tracked by ballistically ejected plasmons from a precessing nozzle, observations on the ...
the influence of Africa upon him, as well as to his desire to further the cause of mutual understanding between western nations and the newly-emerging African states. In his foreword the author does not forget to pay tribute to the British Museum and the Wellcome Historical Medical Library. He begins with an account of prehistoric times, followed by a review of Egyptian, Greek, Roman, Arabian a...
In the first half of the nineteenth century it was commonly supposed that new cells arose either exogenously, outside pre-existing cells, or endogenously, from small rudiments that appeared within pre-existing cells and gradually grew larger. The theory of exogeny had been founded by Wolff (1759), and was supported especially by Link (1807), Schwann (1839), and Vogt (1842). The theory of endoge...
