The Polymerase Chain Reaction (PCR) has facilitated the detection of unculturable
microorganisms in virtually any environmental source and has thus been used extensively in the …

Since many of man's earliest crops (eg, the cereals) were carried about as seed, pathogens
must certainly have been carried with them. The relation ship of certain lots of seed to …

Actual and perceived social isolation are both associated with increased risk for early
mortality. In this meta-analytic review, our objective is to establish the overall and relative …

This work investigated the influence of different concentrations of calcium on the growth of
plantlets of the bromeliad Aechmea blanchetiana cultured in vitro. Seedlings of A. …

The evolution of anisogamy or gamete size dimorphism is a fundamental transition in
evolutionary history, and it is the origin of the female and male sexes. Although mathematical …

A semianalytical radiance model is developed which predicts the upwelled spectral radiance
at the sea surface as a function of the phytoplankton pigment concentration for Morel Case …

A bio‐optical technique is presented which allows both the classification and optical modeling
of natural waters. The spectral diffuse attenuation coefficient for irradiance (300–700 nm) …

A new UV submersible spectroradiometer has been employed to determine the diffuse
attenuation coefficient for irradiance in the clearest natural waters [Kw(λ)] with emphasis on the …

This paper describes the first synthesis of a new class of topological macromolecules which
we refer to as “starburst polymers.” The fundamental building blocks to this new polymer …

Background A safe and efficacious vaccine against severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2), if deployed with high coverage, could contribute to the control of …
