The Boston University-Five College Radio Astronomy Observatory Galactic Ring Survey is a new survey of Galactic CO J = 1 → 0 emission. The survey used the SEQUOIA multi pixel array on the Five College Radio Astronomy Observatory 14 m telescope to cover a longitude range of l = 18– 55.7 and a latitude range of |b| < 1, a total of 75.4 square degrees. Using both position-switching and On-The-Fly ...

We used mitochondrial DNA and microsatellite loci to examine the phylogeographic patterns of the most broadly distributed lizard in eastern North America, the five-lined skink (Eumeces fasciatus). We infer that longitudinal phylogeographic patterns in E. fasciatus are consistent with fragmentation due to refugial and post-glacial dynamics, but that deep divergences within the species imply hist...

in order to identify different types of effective weather on patterns of inversion in mashhad, the researchers first prepared the inversion statistics, then, the sea level pressure and finally they prepared access to the zero meeting gmt cumulative 2.5 degrees in the range 20 to 47.5 degrees to 67.5 degrees north and 35 east center, university ncep angelia east of england norwich city. then for...

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...

Urbanization is one of the major forms of habitat alteration occurring at the present time. Although this is typically deleterious to biodiversity, some species flourish within these human-modified landscapes, potentially leading to negative and/or positive interactions between people and wildlife. Hence, up-to-date assessment of urban wildlife populations is important for developing appropriat...

Groundwater is one of the most important water resources especially for irrigation in the east of Iran. So, it is important to note its water quality variation for deciding to manage it. To this end, the study were done to zone Birjand plain located at latitude between 32˚ 30’-33˚ 00’ N and longitude between 58˚ 45’-59˚ 41’ E. In order to achieve this goal, the required layers, Sodium adsorptio...

Synchronous satellites of Venus have long been thought unstable, but we use Poincare's surface section technique to show that synchronous quasi-satellites orbiting just outside Venus' Hill sphere are quite stable, at least for centuries. Such synchrosats always remain within a few degrees equator, and drift very slowly in longitude. These could be useful continuous monitoring points on surface,...

The main objective of this study is to determine the different tree communities in forest Pobè and characterize their structure ecology contribute sustainable management forest. located between parallels 6° 57' 20" 58' 04" north latitude 2° 39' 46" 40' 45" east longitude. sampling used for data collection one central plot 1 hectare (100 m x 100 m) at center a square 4 ha (200 200 m).

Interactions between hosts and associated microbial communities can fundamentally shape the development and ecology of 'holobionts', from humans to marine habitat-forming organisms such as seaweeds. In marine systems, planktonic microbial community structure is mainly driven by geography and related environmental factors, but the large-scale drivers of host-associated microbial communities are ...
