The influence of flow rates and water depth gradients on the growth process of submerged macrophytes and the biomass composition of the phytoplankton assemblage in eutrophic water: an analysis based on submerged macrophytes photosynthesis parameters.
Abstract Submerged macrophytes and phytoplankton assemblage play significant roles in the functioning of aquatic ecosystems. An experiment was carried out in Beijing in order to further evaluate the environmental factors that affect the growth of submerged macrophytes and phytoplankton assemblage. Submerged macrophytes (i.e., Vallisneria natans, Hydrilla verticillata, and Ceratophyllum demersum) constructed the growth system with some controllable influencing factors (i.e., the flow rate and water depth gradient). The flow rates were set separately as 4 L/h (1#), 6 L/h (2#), and 12 L/h (3#), while t...

Deposition and dispersion characteristics of ultrafine particles under different vehicle speeds in road tunnels employing dynamic mesh simulation.
We present a realizable k-ε turbulence model based on a combination of Eulerian passive scalar and dynamic mesh models. A 100-m three-dimensional model of a road tunnel containing four vehicles in a row and 10-m long outlets was established using STAR-CCM+ computational fluid dynamics software. Ultrafine particles derived from vehicle exhaust gas were modeled at velocities of 60, 40, and 20 km h-1. The diameter and number of particles ranged from 26 to 287 nm and 1.7 × 104-1.7 × 105 cm-3, respectively. The results show that, in the vertical plane (located 0.1 m behind the exhaust pipe), the deposition e...

Biological responses at the interface of Ti-doped diamond-like carbon surfaces for indoor environment application.
In this study, we show that the operating conditions of titanium-doped DLC coatings used for implants in surgical devices significantly modify their surface properties and consequently their interaction with cells. The coatings showed uniform distribution on the substrate and their biocompatibility was tested by way of rat calvaria osteoblasts. Doping DLC with Ti changed the roughness and wettability of the film interface. The autoclaving of the samples led to the surface oxidation and the formation of TiO2 on the top-most layers of Ti-doped DLC. This was quantitatively assessed by X-ray photoelectron spectroscopy (XPS) an...

Role of renewable energy and globalization on ecological footprint in the USA: implications for environmental sustainability.
Abstract The role of renewable energy and globalization on ecological footprint is investigated in the USA by controlling for the effects of financial development and real output using quarterly data from 1985:Q1 to 2014:Q4. We apply the minimum Lagrange multiplier unit root test, multiple structural break cointegration test, and autoregressive distributed lag (ARDL) estimation approach. The empirical evidence suggests that, in the long run, renewable energy and real output exert negative pressure on ecological footprint while financial development and globalization exert positive pressure on ecological footprint....

Evaluation of acute and chronic exposure to aflatoxin B1 in indigenous women of the Huasteca Potosina, Mexico.
z B, Rosales-Mendoza S, Flores-Ramírez R Abstract Aflatoxin B1 (AFB1) is one of the most studied mycotoxins due to its high occurrence in food and its hepatotoxic, immunosuppressive, carcinogenic, childhood growth, genotoxic, mutagenic, and teratogenic effects in humans and animals. Exposure to AFB1 is reported to be both, acute and chronic; the main exposure pathway to AFB1 is through the intake of contaminated food. In Mexico, although the reports of several studies addressing the problem of aflatoxins in maize and other foods, the evidence has been centered on exposure to AFB1 and to the quantification o...

Effects of hydrogeochemical conditions on the distribution of pesticides in the karst river system.
Abstract Karst aquifer systems are tended to be polluted compared to other types of aquifers because pollutants are able to enter aquifers through developed conduit systems. To identify the effects of hydrogeochemical conditions on the distribution of pesticides in a karst river system in Kaiyang, southwest China, a typical pollution mode combining intermittent infiltration with intrusion was constructed. Twelve aqueous samples were collected along the karst river, and a total of 24 pesticides were detected. The results showed that the pesticide ubiquity and the dominant organophosphate (40%) and organonitrogen pe...
