Using MINEDWto simulate pore pressure as input for FLAC3Dand 3DEC
It has become common practice to create a three-dimensional (3-D) geomechanical model for the analysis of rock stability. One of the key inputs for a geomechanical model is the 3-D pore-pressure distribution. For complicated geologic settings under excavation, such as open pit walls and underground mine workings, pore pressures generally do not follow hydrostatic distributions with depth; ...

Mercury in the seafood and human exposure in coastal area of Guangdong Province, South China
Consumption of fish and aquatic products is considered to be the main pathway of human exposure to methylmercury (MeHg). To assess human health risk through seafood consumption in a coastal area of Guangdong Province, South China, a total of 518 seafood samples (including fish, shrimp, crabs, and mollusks) were collected from 11 coastal cities for total mercury (THg) analysis. The THg ...

Characteristics of postharvest quality in regional fruits treated with ionising radiation
Quality postharvest of three cultivated species of the Northeast Region of Brazil was evaluated after receiving ionising radiation. Cashew peduncles (Anacardium occidentale L. var. Nanum) stored for 14 days under 6.5°C had presented best results in the sensorial analyses for external appearance, flavour and aroma when irradiated with 1 kGy. Sapodillas (Manilkara sapodilla (L) Van Roy en) ...

The effects of salinity exposure on multiple life stages of a common freshwater mussel, Elliptio complanata
There is growing concern over the effects of increased salinization on freshwater organisms, which are largely unknown for unionid mussels. Adult and larval Elliptio complanata were exposed to low level salt concentrations to determine the effects on mussel survival, physiology, and reproduction. Adults were exposed to salt concentrations of 0, 2, 4, and 6 ppt NaCl and monitored over 7 days ...

The rhizotoxicity of metal cations is related to their strength of binding to hard ligands
Mechanisms whereby metal cations are toxic to plant roots remain largely unknown. Aluminum, for example, has been recognised as rhizotoxic for about 100 years but there is no consensus on its mode of action. We contend that the primary mechanism of rhizotoxicity of many metal cations is non‐specific and that the magnitude of toxic effects is positively related to the strength with which they ...

Moving Up the Food Chain
For most of the time that human beings have walked the earth, we lived as hunter-gatherers. The share of the human diet that came from hunting versus gathering varied with geographic location, hunting skills, and the season of the year. During the northern hemisphere winter, for instance, when there was little food to gather, people there depended heavily on hunting for survival. Our long history ...

Application of generalized linear mixed model to analyze mixture toxicity: Survival of brown trout affected by copper and zinc
Increased concerns about the toxicity of chemical mixtures have led to greater emphasis on analyzing the interactions among the mixture components based on observed effects. The authors applied a generalized linear mixed model (GLMM) to analyze survival of brown trout (Salmo trutta) acutely exposed to metal mixtures that contained copper and zinc. Compared to dominant conventional approaches ...

Predicting the effects of copper on local population decline of two marine organisms, cobia fish and whiteleg shrimp, based on avoidance response
Fry of the marine fish Rachycentron canadum (cobia) and larvae of the estuarine shrimp Litopenaeus vannamei (whiteleg shrimp) were exposed to a copper gradient which ranged from 0.20 to 1.80 mg Cu/L for the experiments with cobia and from 0.10 to 1.0 mg Cu/L for the experiments with whiteleg shrimp. The experiments focused on the avoidance response to predict the population decline. Avoidance ...
