Blue Waters is a Petascale-level supercomputer whose mission is to enable the national scientific and research community to solve"grand challenge"problems that are orders of magnitude more complex than can be carried out on other high performance computing systems. Given the important and unique role that Blue Waters plays in the U.S. research portfolio, it is important to have a detailed under...

In growing certain woody plants in continuously flowing culture solutions it has been found essential to submerge only a portion of the established root system while still maintaining a relatively high humidity around the unsubmerged roots. The following apparatus has been found especially satisfactory for this purpose, allowing the use of ordinary jars of glass or other material as culture ves...

Practitioners in hospitals often ...

OstracodsOstracoda (ostracod), charophytesCharophyta (charophyte) and pollenPollen were retrieved from sediments of the Baynunah Formation. Autoecological characteristics ostracodsOstracoda (ostracod) (charophyte), together with detailed observations on taphonomyTaphonomy ostracodOstracoda valves, provide a reconstruction depositional environments freshwater system. These microfossil assemblage...

The poorly resolved pathway of the sub-thermocline waters (>300 m) within Makassar Strait, primary inflow path Indonesian Throughflow, is investigated using in situ mooring measurements and Argo profiles at entrance to Seas. We focus on strong intrusion summer 2016, when significant changes transport thrice as large interannual standard deviation occurred. Analysis suggests that was drawn from ...

Laboratory and full-scale experiments were conducted for enhancing the coagulation of stabilised surface waters with high organic content by permanganate preoxidation. It was indicated that permanganate preoxidation enhanced both the processes of coagulation and filtration of selected surface waters, River Songhua water, Qitaihe Reservoir water and Ba Reservoir water. Permanganate preoxidation ...

A seasonal study of the life cycle and reproductive biology copepod Calanus finmarchicus – dominant zooplankton species a key link between lower higher trophic levels within southwestern Norwegian Sea - is presented. C. reproduces, feeds accumulates lipids during spring summer surface waters, which enables it to survive overwintering at depth until following spring. An inflow warm saline Atlant...

Climate change is putting increasing pressure on flowing waters. Drastic water level fluctuations in rivers or drying up of small and medium-sized streams all contribute to the biodiversity crisis threatening freshwater ecosystems. Benthic diatoms are important elements biofilm streams. However, knowledge relationship between benthic flow intermittence incomplete, especially regions recently im...

We analyze the properties of a model with four-dimensional brane-localized Higgs type potential of a six dimensional scalar field satisfying the Dirichlet boundary condition on the boundary of a transverse two-dimensional compact space. The regularization of the localized couplings generates classical renormalization group running. A tachyonic mass parameter grows in the infrared, in analogy wi...

according to recent studies, about 60 percent of surface waters and 57 percent ground waters are located in snowy zones in iran. in most areas of northern hemisphere and alpine environment areas, snow melt lead to the maximum instantaneous flow rate and is an important part of annual discharge. the present study investigated the effect of snowmelt on the surface waters and ground waters in baha...
