AIMS AND BACKGROUND In Tuscany, lung cancer mortality in men has shown a decreasing geographical trend over the last 3 decades from the most industrialized north-western coastal areas (Massa-Carrara, Viareggio) to the south-eastern areas (Arezzo, Siena), following the path of the development of industrial activities. The aim of the study was to evaluate lung cancer mortality in males by birth c...

Restriction-endonuclease-site variation of mitochondrial DNA (mtDNA) was used to investigate patterns of geographic and phylogenetic divergence within the rodent genus Onychomys. Onychomys has occupied arid habitats in the western North American deserts, shrub-steppes, and grasslands since the late Tertiary. A phylogenetic analysis of the total mtDNA restriction-site variation throughout the ra...

The western corn rootworm, Diabrotica virgifera virgifera LeConte, is an established insect pest of maize (Zea mays L.) in North America. The rotation of maize with another crop, principally soybeans, Glycine max (L.), was the primary management strategy utilized by North American producers and remained highly effective until the mid-1990s. In 1995, widespread and severe root injury occurred in...

154 specimens of periophthalmus waltoni distributed in seven different sites in the persian gulf and gulf of oman are analysed, utilizing ten morphometric characters. canonical variate analysis (cva) of the sampling sites suggested a partial separation between the north-western sites and the central plus south-eastern sites. the main factor to connect p. waltoni specimens from different sites a...

Chlorofluorocarbon (CFC) and hydrographic data collected in the North Atlantic in the late 1980s and early 1990s are used to confirm and add to earlier work on the large-scale circulation pathways and timescales for the spreading of North Atlantic Deep Water (NADW) components and how these components relate to the hydrographic structure. Throughout he western North Atlantic, high CFC concentrat...

A major question is whether different source regions across the Middle East account for changes in aerosol and dust particle characteristics, which impact Western Iran. Therefore, over a period of sampling from April 2017 to April 2018, dust particles were collected in Western Iran from different cities including Urmia, Sanandaj, Sare-Pole-Zahab, Dehloran and Abadan. The research aim is to comp...
