To the 50th anniversary of hematology service of the Republic of Tatarstan

The article presents an overview of the development of hematology service in the Republic of Tatarstan. The well-known scientist Nikolay Konstantinovich Goryaev (1875-1943), who worked in Kazan for a long time, began to develop this direction and after passing an internship in Germany proposed an improved device for calculating the blood elements known throughout the world. Adherents of Professor Goryaev continued research in the field of hematology, a blood transfusion station was organized. Professor S.I. Sherman proposed new methods of diagnosis and treatment of B12 deficiency anemia. Professor Sh.I. Ratner studied the changes in the blood picture in diseases of the abdominal cavity. The first 15 specialized hematological beds were opened in 1968 in the hospital named “Old Clinic”. The physician who treated such patients was Rakhil Sholomovna Dashevskaya, PhD. At present, hematology service is provided by three hospitals in Kazan, hematological and therapeutical beds in Naberezhnye Chelny and Nizhnekamsk, outpatient hematology service in Zelenodolsk. In recent years, the introduction of stem cell therapy has begun, and modern combined methods of chemotherapy have been introduced

Oxygen dayglow observations on Mars by SPICAM IR on Mars-Express

O2(1Δg) dayglow at 1.27 μm reflects the ozone distribution in the Martian atmosphere as a result of ozone photolysis by solar UV radiation. SPICAM IR on Mars-Express performed continuous observations of the O2 dayglow at limb and nadir from 2004 to 2012 with resolving power of 2200. The results of O2(1Δg) observations have been compared with LMD GCM simulation [1-3] to study its seasonal variations and sensitivity to kinetic parameters

O₂(a¹Δ_g) dayglow limb observations on Mars by SPICAM IR on Mars-Express and connection to water vapor distribution

International audienceThe 1.27-μm O2(a1Δg) dayglow on Mars is a product of the ozone photolysis by solar UV radiation. The intensity of the O2(a1Δg) emission rate depends on ozone concentration, atmospheric density and kinetic parameters of involved photochemical reactions. In turn, the distribution of ozone is sensitive to the vertical and spatial distribution of water vapor, which is an effective destructor of O3. SPICAM IR on the Mars-Express mission measures the O2(a1Δg) dayglow with spectral resolving power of 2200. The results of 147 limb observations from 2004 to 2013 are reported. Limb resolution of the instrument is variable and exceeds the scale height of the atmosphere. The slant emission rate reaches a maximum at the high northern latitudes at northern and southern springs Ls=0-50° and 160-190°, respectively and a minimum in middle and low latitudes at southern summer Ls=200-300°. We have compared the SPIVAM O2(a1Δg) limb profiles with the General Circulation Model simulation by the Laboratoire de Meteorologie Dynamique reduced to the vertical resolution of the instrument. The GCM includes the radiative effect of the water clouds and an interactive dust scheme, and well reproduces Martian Climate Sounder (MCS) temperature profiles. The model underestimates the emission for Ls=0-50°, Ls=160-180° and overestimates it from Ls=60° to Ls=150° at high northern latitudes. In the Southern hemisphere the model underestimates the emission for Ls = 170-200° and overestimates it for Ls = 200-230° at high southern latitudes. The disagreement could be related to the water vapor distribution as the model reproduces it. The most recent version of the LMD GCM including microphysical representation of cloud formation taking into account the effect of dust scavenging by water ice clouds gives much better agreement with SPICAM O2(a1Δg) dayglow limb observations. Characterization of the Mars water cycle by GCMs continues to improve, and the observations of the O2(a1Δg) dayglow offer a powerful tool for its validation
