The absence of any marked geographical variability at small area scale argues against a geographically varying environmental factor operating strongly in the aetiology of testicular cancer.
Geographical variability was low and characteristics of the household did not influence THM levels.
The results of the analysis reveal a significant degree of geographical variability in the travel behavior of seniors in Montreal.
These principles are topical questions for biological risk and particularly zoonoses, because of their constant evolution, their geographical variability, and their emergence or reemergence.
In a setting with low geographical variability and limited environmental measurements, individual data is highly relevant to determine personal THM exposure and uptake.
The implementation of dosimetry in 131I-NaI treatments for benign thyroid disease is compulsory in some countries, which may explain the geographical variability, as further highlighted in Fig. 4.
We calculated weekly averages for the whole geographic area of the dataset in Finland and for two smaller geographical areas (see Figure 1) to study the geographical variability of the observations.
The aim of this study is to analyze the geographical variability of the severity of traffic accidents in Spain, from 1985 to 1994, and to compare several severity indicators.
Probabilistic material flow analysis and graph theory were combined to calculate predicted environmental concentrations (PECs) of engineered nanomaterials (ENMs) in Swiss rivers: 543 river sections were used to assess the geographical variability of nano-TiO2, nano-ZnO and nano-Ag, and flow measurements over a 20-year period at 21 locations served to evaluate temporal variation.
These two traits are well suited as surrogates for the life history and geographical variability among bird species [21].
The patterns and amplitude of density variation show considerable geographical variability, and both stable and cyclic populations are found [46].
