With wetlands categorized as one of the three major ecosystems, the study of wetland health has global environmental implications. Multiple regression models were employed to establish relationships between Landsat-8 images, vegetation indices and field measured biomass in the Yellow River Delta Nature Reserve. These models were then used to estimate the spatial distribution of wetland vegetative biomass. The relationships between wetland vegetative biomass and soil factors (organic matter, nitrogen, phosphorus, potassium, water soluble salt, pH and moisture) were modeled. We were able to achieve higher correlations and improved model fits using vegetative indices and spectral bands 1-5 as independent variables. Several important soil factors were isolated, including soil moisture and salt concentrations, which affect wetland biomass spatial distributions. Overall, wetland biomass decreased from land to the ocean and from the river courses outward.

Qinghai-Tibet Plateau wetland, an important component of terrestrial ecosystem, plays an essential role in global carbon cycling. To understand the variation of organic carbon storage in vegetation-so...
Engineered nanomaterials (ENMs) are increasingly produced and consequently released into the environment. Therefore, there is a strong need to find a valid way to treat the ENMs pollution. In this stu...
Wetland ecosystems are known to mitigate high nutrient loadings and thus can improve water quality and prevent potential biodiversity loss caused by eutrophication. Plant traits affect wetland process...
Generative adversarial networks (GANs) learn a deep generative model that is able to synthesize novel, high-dimensional data samples. New data samples are synthesized by passing latent samples, drawn ...
The purpose of this study is to determine whether immune globulin can limit the amount of yellow fever vaccine virus present in the blood after vaccination without compromising the immunit...
The objective of this study is to study immune memory generated against the yellow fever vaccine (YFV) in participants who recently received the YFV vaccine. Volunteers who are planning ...
Yellow fever is an acute viral disease transmitted by mosquitoes in South America, Central America and Africa. It is more prevalente in males gender and the age above 15 years due to the g...

Vaccine used to prevent YELLOW FEVER. It consists of a live attenuated 17D strain of the YELLOW FEVER VIRUS.
A rare condition characterized by the presence of yellow nails, LYMPHEDEMA, and/or PLEURAL EFFUSION with respiratory tract involvement. Abnormal lymphatic network may play a role in its etiology. Occasionally inherited, yellow nail syndrome mostly is sporadic without apparent family history.
Common treatment method used in pediatric dentistry that involves the use of fixed or removable space maintainers in order to keep the space left by a baby tooth safe in the event it is lost early. Space maintainers also help permanent teeth to grow safely.
An environment simulating one or more parameters of the space environment, applied in testing space systems or components. Often, a closed chamber is used, capable of approximating the vacuum and normal environments of space. (From NASA Thesaurus, 1988) This also includes simulated EXTRAVEHICULAR ACTIVITY studies in atmosphere exposure chambers or water tanks.
A genus in the family XANTHOMONADACEAE whose cells produce a yellow pigment (Gr. xanthos - yellow). It is pathogenic to plants.
