An Improved New YOLOv7 Algorithm for Detecting Building Air Conditioner External Units from Street View Images.

Street view images are emerging as new street-level sources of urban environmental information. Accurate detection and quantification of urban air conditioners is crucial for evaluating the resilience of urban residential areas to heat wave disasters and formulating effective disaster prevention policies. Utilizing street view image data to predict the spatial coverage of urban air conditioners offers a simple and effective solution.

Single and combined effects of selected haloacetonitriles in a human-derived hepatoma line.

Haloacetonitriles (HANs) are nitrogenous disinfection byproducts (N-DBPs) detected in drinking water that have high toxicity and are a high risk to human health. The cytotoxicity and genotoxicity as well as the oxidative stress of five HANs, namely chloroacetonitrile (CAN), dichloroacetonitrile (DCAN), trichloroacetonitrile (TCAN), bromoacetonitrile (BAN), and dibromoacetonitrile (DBAN) on a hepatoma cell line (HepG2) were determined by single, binary or ternary exposure. The median effective concentrations, based on cell viability, ranged from 0.

Bioconcentration, metabolism and effects of diphenhydramine on behavioral and biochemical markers in crucian carp (Carassius auratus).

Diphenhydramine (DPH), an antihistamine used to alleviate human allergies, is widespread in aquatic environments. However, little is known about the biochemical and behavioral effects of DPH on non-target aquatic animals. In the present study, the tissue distribution, bioconcentration, metabolism, biochemical and behavioral effects were investigated in crucian carp (Carassius auratus) exposed to various concentrations of DPH (0.
