The species is named after the Lord Buddha who was born in Nepal.</p> <p> DIFFERENTIAL DIAGNOSIS. <i>Temnothorax buddha</i> sp. n. may be confused with Himalayan species such as <i>T</i>. <i>microreticulatus</i> Bharti et al., 2012, <i>T</i>. <i>pamiricus</i> (Ruzsky, 1902), <i>T</i>. <i>pakistanensis</i> Rasheed et al., 2020, and <i>T</i>. <i>himachalensis</i> Bharti et al., 2012, which also have unicolorous yellow body. But from the first species <i>T</i>. <i>buddha</i> sp. n. is distinguished by a more strongly sculptured and longer head (CI 1.26 <i>vs</i> max 1.17) and mesosoma, thinner propodeal spines, much rounded petiole node, shorter and broader petiolar peduncle and massive postpetiole. The new species differs from <i>T</i>. <i>pamiricus</i> and <i>T</i>. <i>himachalensis</i> in much longer propodeal spines, developed strong sculpture, petiole shape, etc. <i>T</i>. <i>buddha</i> sp. n. differs from <i>T</i>. <i>pakistanensis</i> in shorter head (CI 1.26 <i>vs</i> min 1.26 and max 1.32) and scape (SI1 0.65 <i>vs</i> min 0.72), absence of deep metanotal groove, longer propodeal spines, shape of petiole, and coarser sculpture of body.</p>Published as part of <i>Subedi, I.

Skvortzov graduated from Imperial Kazan University with MD degree. All his life was connected with medical and educational activities. Scientific interests mainly concerned hygiene and microbiology. He was the author of some original microbiological hypothesis. I.P. Skvortzov made a great input to Russian and international science in the end of XIX century. This historical review opens for the first time I.P. Skvortzov for Western readers
Notes on meteorological balloon mission planning
No full textIn the 21st century the high altitude gas balloon remains an indispensable tool in atmospheric science, meteorology and other applications requiring stratospheric observations. A prerequisite of the effectiveness of many types of balloon operations is an accurate trajectory forecasting capability, complete with appropriate error estimates. This is particularly important in targeted flights, sample return missions or flights of expensive instruments, whose recovery is essential. The ASTRA (Atmospheric Science Through Robotic Aircraft) initiative led to the development of such a forecast model, which is at the centre of the present paper. A key source of error in such models is our incomplete understanding of the drag opposing the rise of balloons in the free atmosphere – here we propose a new, stochastic model based on empirical data derived from thousands of radiosonde flights. We also examine other sources of prediction error affecting the accuracy of the flight path forecast, such as uncertainties in the wind profile and balloon envelope manufacturing variability. A Monte Carlo framework is used to provide probabilistic touchdown point estimates taking these error sources into account. The above elements have been integrated into a web service, which can be used as a flight planning tool – here we review the key features of its architecture
Maxim Gorky and the Publishing House of I.P. Ladyzhnikov (Based on Archival Materials)
No full textBased on the hitherto unpublished archival materials, this article examines the history of creation and specific traits of an obscure small Russophone Publishing house of I.P. Ladyzhnikov. It also analyzes the role and the scope of Maxim Gorky’s contribution to the work of this publishing house. It is shown that Gorky was one of the founders of this Berlin-based firm. Not only was he an ideological inspirator of this new business, he also supported it financially. As a result of collective efforts on behalf of Gorky and prominent leaders of the Bolshevik party in 1905, the Russianlanguage publishing house was established abroad. By publishing the works of Gorky and other democratic writers of the Znanie group, it secured their copyright in Europe and America and contributed part of its income to the Bolshevik party funds. In 1905–1912, under the direction of Ladyzhnikov, all new works of Gorky were published by this press. The peak of the Publishing house of I.P. Ladyzhnikov fell upon the most fruitful creative period in the life of the main author of this publishing house — M. Gorky. At the end of 1912 Ladyzhnikov was forced to transfer his business to his partner — B.N. Rubinstein, due to financial difficulties. However, the publishing house continued to exist until 1932. The article examines in detail the lesser-studied postrevolutionary period of the Publishing house of I.P. Ladyzhnikov under the leadership of Rubinstein and demonstrates Rubinstein’s significant participation in the translation and publication of Gorky’s works, including translations and productions of his plays abroad
