Continuous observations in the ionospheric E and F regions have been regularly carried out since the ®fties of this century at many ionosonde stations. Using these data from 31 European stations long-term trends have been derived for di€erent parameters of the ionospheric E layer (h¢ E, foE), F1 layer (foF1) and F2 layer (hmF2, foF2). The detected trends in the E and F1 layers (lowering of the ...

The tumorigenic activities of benzo(e)pyrene, 9,10-dihydrobenzo(e)pyrene, 9,10-epoxy-9,10,11,12-tetrahydrobenzo(e)-pyrene, the diastereomeric bay-region 9,10-dihydroxy-11,12-epoxy-9,10,11,12-tetrahydrobenzo(e)pyrenes, and the K-region benzo(e)pyrene 4,5-oxide were assessed in newborn mice, Swiss-Webster mice received a total dose of 0.7 mumol of compound divided into three i.p. injections of 0....

Let $p$ be an analytic function defined on the open unit disc $mathbb{D}$ with $p(0)=1.$ The conditions on $alpha$ and $beta$ are derived for $p(z)$ to be subordinate to $1+4z/3+2z^{2}/3=:varphi_{C}(z)$ when $(1-alpha)p(z)+alpha p^{2}(z)+beta zp'(z)/p(z)$ is subordinate to $e^{z}$. Similar problems were investigated for $p(z)$ to lie in a region bounded by lemniscate of Bernoulli $|w^{2}-1|=1$ ...

determining the relative sensitivity of land to erosion and its factors, could be the basis of soil conservation programs. the aim of this study is to compare water and wind erosion functions in land degradation of dasht-e-jeihoon using psiac and irifr.ea models and the source studying of aeolian sediments in geomorphologic facieses as homogeneous units. the results indicate that in dasht-e-jei...
