I.P. skvortzov and imperial Kazan university
No full text© 2019, Ecozone, OAIMDD. All rights reserved. Irinarkh Polikhronievich Skvortzov was a famous Russian scientist. He was born on 5 August, 1847. I.P. 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
The time course for the abdominal-edematous effects of i.p. carrageenan (1.5%) in adult zebrafish.
No full text<p>The photographic images show the gross pathology of the abdomen in the lateral view following i.p. injection of vehicle (PBS) plus i.p. injection vehicle (PBS) (A and E) and i.p. injection vehicle plus i.p. injection of 1.5% carrageenan at each time point (B–D and F–H). Images A–D were taken at 0 h after i.p. injection of vehicle or 1.5% carrageenan; images E, F, G, and H were taken at 24 h after i.p. injection of vehicle and 8, 16, and 24 h after 1.5% carrageenan injection. Scale bars: 5 mm for images A–H. The increase of the lateral area of the abdomen was given as a difference change from the basal values by subtracting the basal lateral area from the lateral area measured at each time point. Time course of change of the lateral area of abdomen induced by i.p. injection of vehicle (PBS) or carrageenan in adult zebrafish using a photographic image analysis system (I). Compared with the i.p. vehicle groups, the lateral area of abdomen increased progressively in the i.p. 1.5% carrageenan groups until 24 h. Sections (2 µm) of zebrafish abdominal tissues at 24 h after an i.p. injection of vehicle (J) or carrageenan (K). I.p. carrageenan dramatically induced leukocyte infiltration (arrows) in the intestine. Scale bars: 100 µm for images (J) and (K). Each bar in Figure (I) represents the mean ± SEM of 9 adult zebrafish per group. *<i>P</i><0.05 compared with the same time points in the i.p. vehicle (PBS) group.</p
Dual mode fused optical fiber couplers suitable for mode division multiplexed transmission
No full textWe experimentally demonstrate 2 × 2 and 3 × 3 fused fiber couplers made from dual mode fiber. A unique mode dependent power transfer characteristics as a function of pulling length is obtained that support various optical functionalities. Exploiting this we demonstrate several devices of interest for mode division multiplexed data transmission including LP11 mode filter, LP11 mode tap coupler, and 50:50 power splitter for both LP01 and LP11 modes
