In addition to common vegetative multiplication, potato crop can be reproduced by true potato seed (TPS). Only the limited number of pests and diseases, which are the most important causes of a decrease in potato production, can be transmitted by true potato seed. Hence, to evaluate the potential of true potato seed in comparison to potato seed tuber and mini tuber, an experiment was conducted ...

The binding energy and geometrical structure of all the possible dimeric systems of isothiocyanic acid (HNCS) with ozone have been investigated in the gas phase, theoretically. Six minima located on the singlet potential energy surface of the HNCS–ozone system at the MP2 level with binding energies (corrected with ZPE and BSSE) in the range 492.29–531.40 kcal/mol. All intermolecular interaction...

[1] The 11-year solar cycles in ozone and temperature are examined using new simulations of coupled chemistry climate models. The results show a secondary maximum in stratospheric tropical ozone, in agreement with satellite observations and in contrast with most previously published simulations. The mean model response varies by up to about 2.5% in ozone and 0.8 K in temperature during a typica...

Aims Myostatin and Myocyte Enhancer Factor 2C (MEF2C) are involved in muscle changes associated with bone problems. The aim of the present study was to determine the effect of three therapeutic methods of exercise, ozone, and stem cells on MEF-2C gene expression and myostatin levels of femoral muscle tissue in osteoarthritis rats. Methods & Materials This experimental study was done on 63 male...

Regional ozone pollution has become one of the top environmental concerns in China, especially in those economically vibrant and densely populated regions, such as North China region including Beijing. To address this issue, surface ozone and ancillary data over the period 2004–2006 from the Shangdianzi Regional Background Station 5 in north China were analyzed. Due to the suitable location and...

We examined the role of γδ T cells in the induction of alternatively activated M2 macrophages and the resolution of inflammation after ozone exposure. Wildtype (WT) mice and mice deficient in γδ T cells (TCRδ-/- mice) were exposed to air or to ozone (0.3 ppm for up to 72h) and euthanized immediately or 1, 3, or 5 days after cessation of exposure. In WT mice, M2 macrophages accumulated in the lu...

26 In situ tropospheric ozone measurements by balloon borne electrochemical concentration cell 27 (ECC) sensors above Ahmedabad in western India from May 2003 to July 2007 are presented, 28 along with an analysis of the transport processes responsible for the observed vertical ozone 29 distribution. This analysis is supported by 12-day back trajectory calculations using the 30 FLEXPART Lagrangi...
