The Vexing Case of Igor Shafarevich, a Russian Political Thinker

The Russian mathematician, academician and former dissident Igor Shafarevich (b. 1923) is commonly mentioned in Western scholarly studies on perestroika and post-perestroika-era Russian politics as one of the most notable anti-Semites and extreme nationalists of the country. This notoriety owes to Shafarevich’s old samizdat article Russophobia, which was published in 1988. The scandal surrounding Russophobia came to a head when the president of The National Academy of Sciences in the United States asked Shafarevich, its honorary member, to resign. Nothing like this had ever happened in the academy’s history. The present dissertation discusses Shafarevich’s political activities, his texts and ideas as well as their reception. Particular attention is given to Russophobia, whose detailed examination proves very clearly that its reputation as an anti-Semitic text is groundless. The reasons for Russophobia’s hasty but fierce condemnation were many, but only one was that when the Soviet system began to tumble, it was commonly assumed that a vigorous rise in anti-Semitism and extreme nationalism in the Soviet Union/Russia would be just a matter of time. Many observers were highly sensitised to detecting its signs and symptoms. The dissertation also shows that most of those to write the first criticisms of Russophobia and to liken Shafarevich to the ideologues of Nazi Germany were the same people he had criticised in Russophobia for their deterministic view of history and irrational manner of connecting things for the purpose of fanning the flames of distrust between Russia’s Jews and Russians. In retrospect, it is fairly evident that Shafarevich actually managed to effectively “neutralise” the message of many of those obsessed with the Jews among his Russian contemporaries and contributed to the fact that anti-Jewish sentiments have been a great deal less popular in post-communist Russia than so many had feared and expected. The thesis also thoroughly discusses Shafarevich’s other texts and activities before Russophobia’s appearance and after it. In the 1970s, Shafarevich was one of the best-known dissidents in the Soviet Union. He worked together with academician Andrei Sakharov in a dissidents’ unofficial human rights committee and co-operated closely with Aleksandr Solzhenitsyn before Solzhenitsyn’s exile. Then, during the chaotic years of perestroika, Shafarevich defended the basic rights of ordinary citizens and warned that the hype concerning democracy could become counterproductive if the most palpable result of the reforms was the disappearance of citizens’ basic security and elementary social justice. One of the conclusions of the thesis is that even if the world around Shafarevich has changed considerably, his views have remained essentially the same since the late 1960s and early 1970s.

Zeeman effect of NQR in 4,6-dichloropyrimidine and 6-chloro 2,4-dimethoxypyrimidine

Zeeman (35Cl) NQR studies in polycrystalline samples of 4,6-dichloropyrimidine and 6 chloro 2,4 dimethoxypyrimidine show that the asymmetry at the four chemically inequivalent chlorine sites in the former is about 10%, while in the latter (one line) the asymmetry is almost zero. Using a valence-bond picture, C-Cl bonds in 4,6-dichloropyrimidine have been characterised, and the results are also compared with those in a corresponding benzene compound using a simple molecular orbital calculation. The axial symmetry of C-Cl bond in the second compound has been attributed to mesomeric effects.

Phenology and seasonality in the tropical deciduous forest of Bandipur, South India

A long term study on the phenology of tree species of tropical dry deciduous forest ecosystem of Bandipur, South India has revealed patterns of strong seasonality with respect to leaf and fruit initiation as well as their abscission. The distribution of the duration of the various phenological events was observed to be skewed and there was little interannual variation in events such as flowering and fruiting. This suggests that there are, perhaps, no mast flowering or fruiting species present in the deciduous forests. The phenological changes appear to influence the food, feeding, movement patterns and sociality of the major mammals of this dry deciduous ecosystem.

Effect of viscosity on internal waves from a source in a wall

The solution for a line source of oscillatory strength kept at the origin in a wall bounding a semi-infinite viscous imcompressible stratified fluid is presented in an integral form. The behaviour of the flow at far field and near field is studied by an asymptotic expansion procedure. The streamlines for different parameters are drawn and discussed. The real characteristic straight lines present in the inviscid problem are modified by the viscosity and the solutions obtained are valid even at the resonance frequency.

Some properties of indium-tin oxide-films

Thin films of indium-tin oxide have been deposited by DC diode sputtering from an indium-tin alloy target in an argon, hydrogen and oxygen atmosphere. Films with sheet resistance of 11 ohms/square and 80% light transmission have been obtained. The effect of cathode composition and gas mixture on sheet resistance and optical transmission properties of the films have been studied.

Mapping of assembled epitopic regions of human chorionic gonadotropin reveals proximity of CTP alpha to the determinant loop beta 93-100

Three overlapping assembled epitopes of beta hCG have been mapped using MAb probes and a single step solid phase radioimmunoassay. These epitopes have been shown to be at receptor binding region comprising of the loop region beta Cys93-Cys100. Importance of disulphide bonds in maintaining integrity of these epitopes is assessed. Two MAbs (INN 58 and INN 22) interact with the beta region as well as the alpha C-terminal peptide, while the other MAb INN 24 interacts with only the beta region. Cross-reactivity pattern with beta hCG and hLH as web as the reported crystal structure of hCG substantiates the epitope identification. The results demonstrate utility of MAbs as probes in investigations on three-dimensional structure of gonadatropins.
