INTRODUCTION UNSCEAR (1) reported that the effective doses due to inhalation of radon (Rn) and its progeny account on average for about one-half of all natural sources of radiation. In recent years, indoor surveys in Europe and Asia revealed that the dose contribution from thoron (Rn) and its progeny can equal to or even exceed that of Rn and its progeny (2). For assessment the public exposure ...

Exposure to estrogenic endocrine disruptors (EDCs) during development affects fertility, reproductive and non-reproductive behavior in mammals and fish. These effects can also be transferred to coming generations. In fish, the effects of developmental EDC exposure on non-reproductive behavior are less well studied. Here, we analyze the effects of 17α-ethinylestradiol (EE2) on anxiety, shoaling ...

Cocoa in Ecuador is one of the main crops economic importance, mainly for small and medium farmers on coast. Sexual self-compatibility most important criteria selection clonal plants from members hybrid progeny. Trees with higher levels are those that tend to produce earlier compared self-compatible ones. The study consisted selecting 333 trees a group 71 progenies, based such as productivity h...

background: alpha particle irradiation from radon progeny is one of the major natural sources of effective dose in the public population. oncogenic transformation is a biological effectiveness of radon progeny alpha particle hits. the biological effects which has caused by exposure to radon, were the main result of a complex series of physical, chemical, biological and physiological interaction...

Tree fruit breeding is an inherently long-term process. The average generation time can range from 2 to 20 years depending on the species. While the production of large numbers of progeny favors the appearance of rare but desired recombinants, large tree size limits the number of progeny that can be planted and maintained. Significant genotype x environment interactions require multiple test si...

The objective of this study was to select Pinus kesya progenies by the estimation of genetic parameters using the method of restricted maximum likelihood (Reml) and prediction of additive genetic values by the best linear unbiased prediction (Blup). The Pinus kesya progeny test was installed in randomized blocks, which consisted of 30 progenies and three replications. The twenty-year-old trees ...
