background: historically open surgical drainage has been the treatment of choice for pyogenic liver abscess. the records of 54 patients with pyogenic liver abscess were reviewed to determine whether earlier diagnosis with current imaging tests and definitive treatment with antibiotics and aspiration drainage was an effective alternative to surgery. methods: the clinical features, laboratory tes...

The successful functioning of a bioretention system depends on the use of suitable soil media. Predictive computer modelling of a bioretention system (e.g. using the MUSIC software) assumes specific characteristics of the soil media to achieve a certain level of stormwater treatment. Therefore, the soil media used in the construction of a bioretention system must exhibit the required characteri...

The seasonal variation of fecal coliforms (FCs) and physicochemical factors was determined in seawaters of the Hansan-Geojeman area, including a designated area for oyster, and in inland pollution sources of its drainage basin. The mean daily loads of FCs in inland pollution sources ranged from 1.2 × 10 to 3.1 × 10 most probable number (MPN)/day; however, the pollutants could not be reached at ...

This paper evaluates the different AREMA gradations currently in use for their effects on both ballast void space and load carrying performances using a discrete particle analysis computational technique called Discrete Element Modeling (DEM). The effect of gradation on aggregate assembly volumetric properties was first studied. Full-scale ballast layers with common gradations listed in AREMA s...

A generalization of the single soil layer variable infiltration capacity (VIC) land surface hydrological model previously implemented in the Geophysical Fluid Dynamics Laboratory general circulation model (GClVO is described. The new model is comprised of a two-layer characterization of the soil column, and uses an aerodynamic representation of the latent and sensible heat fluxes at the land su...

The boundary layer flow and heat transfer on a stretched surface moving with prescribed skin friction is studied for permeable surface. The surface temperature is assumed to vary inversely with the vertical direction x for n = -1. The skin friction at the surface scales as (x) at m = 0. The constants m and n are the indices of the power law velocity and temperature exponent respectively. Simila...

Outburst closed distance coal seam distances are extremely difficult to mine, and commonly involved in safety accidents the process of mining. Based on engineering background Wulan Coal Mine at western margin Ordos Basin, this paper presents a theoretical analysis, analogies, numerical simulations determine optimal mining sequence for #7, #8, #2, #3 seams. Floor penetration drilling was used el...

The floodplains of many gravel-bed streams have a general stratigraphy that consists of a layer of topsoil covering gravel-dominated subsoil. Previous research has demonstrated that this stratigraphy can facilitate preferential groundwater flow through focused linear features, such as paleochannels, or gravelly regions within the vadose zone. These areas within the floodplain vadose zone may pr...

Extracellular polymeric substances (EPS) play important roles in regulating the dewaterability of sludge. This study sought to elucidate the influence of EPS on the dewaterability of sludge during bioleaching process. Results showed that, in bioleaching system with the co-inoculation of Acidithiobacillus thiooxidans TS6 and Acidithiobacillus ferrooxidans LX5 (A. t+A. f system), the capillary su...
