The landscape pattern of Daqing City, China has undergone a significant change during the last two decades as a result of rapid urbanization. A quantitative analysis describing the spatial fragmentation caused by urban sprawl from satellite images was presented on three dates: 1979, 1990, and 2000. Five landscape indices with supplementary ecological meanings were chosen to facilitate our exami...

We investigated the effects of familial sinistrality (FS+; presence of left-handedness in one's close relatives), manual preference strength (MPS), and head size on the hemispheric lateralization of language in right-handers. Functional magnetic resonance imaging was used to map 49 individuals while listening to a story in their mother tongue. We found that individuals who had both the FS+ trai...

The relationship between microparticle (MP) size and lung targeting efficiency, intra-lung distribution and retention time was systematically studied after intravenous administration of rigid fluorescent polystyrene MPs of various sizes (2, 3, 6 and 10 microm) to Sprague Dawley rats. Total fluorescence was assessed and it was found that 2 microm and 3 microm MPs readily passed through the lung ...

China, like many other countries in the world, has declining biodiversity caused by urbanization. Urban parks are a patchwork of distinct biotopes and have significant conservation value for biodiversity. Biotope mapping is an essential tool urban conservation, ecological spatial planning ecosystem management, however there few studies on it China. This study explores practical scheme biotope c...

Scientific interpretation of the mechanism of land use change is important for government planning and management activities. This study analyzes the land use change in Jiangsu Province using three land use maps of 2000, 2005 and 2008. The study results show that there was a significant change in land use. The change was mainly characterized by a continuous built-up land expansion primarily at ...

Microplastics (MPs) in marine and terrestrial environments have been intensively studied, but the dynamics of airborne MPs remains limited. Existing studies on atmospheric are mostly derived from collection deposition, whereas direct measurements scarce. However, abundance is more relevant for evaluating human inhalation exposure risk. Herein, indoor outdoor urban rural areas a coastal city eas...

UNLABELLED There is increasing concern about radiation exposure from myocardial perfusion SPECT (MPS). γ-cameras with solid-state cadmium-zinc-telluride (CZT) detectors have better count sensitivity and spatial resolution than conventional sodium iodine detectors, allowing for significant reductions in radiotracer dose or acquisition time. This study aimed to demonstrate the capability of a hyb...

We consider a version of the contact process with sexual reproduction on a graph with two levels of interactions modeling metapopulations. The population is spatially distributed into patches and offspring are produced in each patch at a rate proportional to the number of pairs of individuals in the patch (sexual reproduction) rather than simply the number of individuals as in the basic contact...

Atmospheric microplastics (MPs) have been consistently captured within air samples on a global scale. Locations with high human activity are reported to MP levels. An urban sampling site in the Humber region (U.K.) has sampled over 13-month period, providing seasonal variation profile of levels, size, shape, and polymer types that humans exposed to. Mean measured using passive fallout into cont...
