To study organochlorine pesticides and organophosphorus pesticides contents and assess pesticideinduced health risk in Armenia,the contents of pesticides were determined in 252 soil samples taken from relatively large plots of agricultural land in 25 rural *** results showed that only∑DDT contents were detected in 39 out of 252 soil *** identified contents of∑DDT mainly consisted of pp’-DDE,suggesting historical use.6 out of 12 rural communities are characterized by the presence of former pesticide storehouses *** excesses versus maximum Acceptable Concentration were observed in 26 out of 39 samples and ranges from 1.03 to 464.9 *** health risk assessment showed that non-carcinogenic risk is below the allowable level(HQmmunities,the presence of observed∑DDT and associated risk to the local population was detected mainly in the majority of sampling sites in Jrashen(Ararat region),Aramus(Kotayq region)and Khanjyan(Armavir region).Therefore,special attention should be given to the riskiest rural communities and risk reduction measures are needed to reduce or eliminate observed carcinogenic health effect.

It is shown that the capture and fission cross-sections of 238U and 239Pu increase with temperature within 1000 K - 3000 K range, in contrast to those of 235U, that under certain conditions may lead to the so-called blow-up modes, stimulating the anomalous neutron flux and nuclear fuel temperature growth. Some features of the blow-up regimes in neutronmultiplying media are discussed.

KamLAND-Experiment and Soliton-Like Nuclear Georeactor. Part 1. Comparison of Theory with Experiment

引用

Journal of modern Physics 2013年第4期4卷 528-550页

作者： V. D. Rusov D. A. Litvinov E. P. Linnik V. N. Vaschenko T. N. Zelentsova m. E. beglaryan V. A. Tarasov S. A. Chernegenko V. P. Smolyar P. O. molchinikolov K. K. merkotan P. E.

We give an alternative description of the data produced in the KamLAND experiment, assuming the existence of a natural nuclear reactor on the boundary of the liquid and solid phases of the Earth core. Analyzing the uncertainty of antineutrino spectrum of georeactor origin, we show that the theoretical (which takes into account the soliton-like nuclear georeactor) total reactor antineutrino spectra describe with good accuracy the experimental KamLAND-data over the years of 2002-2007 and 2002-2009, respectively. At the same time, the parameters of mixing (△m221=2.5×10-5 eV2, tan2θ12=0.437) calculated within the framework of georeactor hypothesis substantially differ from the parameters of mixing ((△m221=7.49×10-5 eV2, tan2θ12=0.436) obtained in KamLAND-experiment for total exposure over the period of 2002-2009. By triangulation of KamLAND and Borexino data we have constructed the coordinate location of soliton-like nuclear georeactors on the boundary of the liquid and solid phases of the Earth core.
