Dust particles have dangerous impacts on human health, the environment, and the economy. Recently dust storms, originating from Arabian countries, have increased remarkably, affecting western and central parts of Iran.HYSPLIT model and the mean monthly maps of AAI (Absorbing Aerosol Index), surface skin temperature, and top soil layer moisture from OMI (Ozone Measurement Instrument) have been u...

The extremal spatial dependence of significant wave height in the North East Atlantic is explored using Joint Altimetry Satellite Oceanography Network satellite altimeter observations for period 2002–2018, and a conditional extremes model motivated by work Heffernan Tawn. analysis involves (a) registering individual passes onto template transect, (b) marginal extreme value at set locations on t...

Ten North Temperate taxa representing diverse angiosperm lineages were analyzed for biogeographic histories using the dispersal-vicariance analysis method to gain insights into the origin and evolution of disjunct distributions in the Northern Hemisphere. Results indicate four general biogeographic patterns: (1) origin and speciation in eastern Asia with subsequent expansion into North America ...

Among the countries that can be classified as Near East Africa, North West Africa, and Western Africa, there is a great diversity of foods and dietary patterns. Prevalence of undernourishment as defined by FAO using dietary energy supply data, varies dramatically among these countries, with Tunisia in the lowest prevalence category (<2.5%), and Sierra Leone in the highest prevalence category (>...

Seismic waves that traverse Earth's inner core along north-south paths produce unusually broad pulse shapes at long periods (compared with waves along east-west paths) and reflections from below the inner core boundary at short periods. The observations provide compelling evidence for a seismic velocity discontinuity along north-south paths about 200 kilometers below the inner core boundary sep...

The Great Basin and Plateau encompass a vast region of western North America bracketed on the west by the Sierra Nevada and Cascade mountains and the east by the Rocky Mountains (Figure 1). The region is diverse but characterized by ecologically limiting, generally more arid conditions, and higher elevations than other parts of North America. It is also characterized by a type of archaeology th...
