We present evidence for a substantial overdensity of stars in the direction of the constellations of Hercules and Aquila. The Cloud is centered at a Galactic longitude of l ≈ 40◦ and extends above and below the Galactic plane by at least 50◦. Given its off-centeredness and height, it is unlikely that the Hercules-Aquila Cloud is related to the bulge or thick disk. More likely, this is a new str...

As widespread deserts is located in west and southwest of Iran plateau, dust storms form due to west andsouthwest systems over Syria or Iraq as well as Arabian Peninsula. These systems severely affect west and southwestregions. Sometimes the fine dusts transmit to central, north east, and east regions. In this study for investigating dustysynoptical patterns, meteorological data at 5 synoptic s...

BACKGROUND Quantifying changes in forest bird diversity is an essential task for developing effective conservation actions. When subtle changes in diversity accumulate over time, annual comparisons may offer an incomplete perspective of changes in diversity. In this case, progressive change, the comparison of changes in diversity from a baseline condition, may offer greater insight because chan...

Spatial variation in growth is a common feature of demersal fish populations which often exist as discrete adult sub-populations linked by a pelagic larval stage. However, it remains unclear whether variation in growth occurs at similar spatial scales for populations of highly migratory pelagic species, such as tuna. We examined spatial variation in growth of albacore Thunnus alalunga across 90...

This article analyzes the main objectives of the scientific voyage to circumnavigate the earth, undertaken by the United States from 1838 to 1842. Charting was one of the most important of the scientific and strategic goals of the exploratory voyage. The initiative for the undertaking was the search for exact positioning on the high seas after the establishment of the longitude system, when nau...

The literature on vertical disparity is complicated by the fact that several different definitions of the term "vertical disparity" are in common use, often without a clear statement about which is intended or a widespread appreciation of the properties of the different definitions. Here, we examine two definitions of retinal vertical disparity: elevation-latitude and elevation-longitude dispar...

BACKGROUND The Canadian-accredited post-baccalaureate Doctor of Pharmacy program at Qatar University trains pharmacists to deliver advanced patient care. Emphasis on acquisition and development of the necessary knowledge, skills, and attitudes lies in the curriculum's extensive experiential component. A campus-based oral comprehensive examination (OCE) was devised to emulate a clinical viva voc...
