Background: The consumption of low quality foods is common in low socioeconomic areas; and according to epidemiological studies, the density of nutrients often proves the quality of diet. This study aimed to compare the density of macronutrients and micronutrients in various parts of Tehran.   Methods: This was a cross-sectional study performed from September to December 2007 in all the...

[1] We apply adjoint models of mantle convection to North America since the Late Cretaceous. The present-day mantle structure is constrained by seismic tomography and the time-dependent evolution by plate motions and stratigraphic data (paleoshorelines, borehole tectonic subsidence, and sediment isopachs). We infer values of average upper and lower mantle viscosities, provide a synthesis of Nor...

Dendrochronological research in North-Central Europe and the East Mediterranean has produced networks of long regional oak (Quercus sp.) reference chronologies that have been instrumental in dating, provenancing, and paleoclimate research applications. However, until now these two important tree-ring networks have not been successfully linked. Oak forests and historical/archaeological sites in ...

2 ABSTRACT The paper argues that the economies of East and South East Asia are a very diverse group, only some of which have grown rapidly over the past three decades. The fast growing economies of South East Asia, especially Indonesia, Thailand and Malaysia are in a number of important respects different from the fast growing economies of North The different colonial legacies have had importan...

The Middle East was a funnel of human expansion out of Africa, a staging area for the Neolithic Agricultural Revolution, and the home to some of the earliest world empires. Post LGM expansions into the region and subsequent population movements created a striking genetic mosaic with distinct sex-based genetic differentiation. While prior studies have examined the mtDNA and Y-chromosome contrast...

Weather and climate have a strong influence on tourism and the recreation sector, which is a very important industry. Since tourism is becoming one of the main industries all over the world, it plays an important role in promoting national and local economic development. This paper attempts to show the role of climate in tourism seasonality and tries to study the impacts of climate resources on...

Three new species of the genus Cypretta Vivra, 1985 are described from Southern Mexico, representing the first record of the genus in the country. Cypretta campechensis n. sp. is closely related to Florida and North Carolina species such as C. nigra Furtos, 1936, C. brevisaepta Furtos, 1934 and C. bilicis Furtos, 1936. Cypretta spinosa n. sp. is related to the North and South American species C...

During the last decades, marine pollution with anthropogenic litter has become a worldwide major environmental concern. Standardized monitoring of litter since 2001 on 78 beaches selected within the framework of the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR) has been used to identify temporal trends of marine litter. Based on statistical analyses ...

Barn Orientation The first freestall barn design criteria to consider should be the orientation of the structure. Barns with a north-south orientation are exposed to greater solar radiation than barns with an east-west orientation. Sunlight enters north-south oriented barns directly in the morning and afternoon. While afternoon sun is the most detrimental, morning sun also can affect cow behavi...

The geology of North-East Greenland (70–78°N) exposes unique evidence the basin development between Devonian collapse Caledonian Orogen and extrusion volcanics at Paleocene–Eocene transition during break-up Atlantic. Here we pay special attention to unconformities in stratigraphic record – do they represent periods stability non-deposition or subsidence accumulation rocks followed by episodes u...
