This work was undertaken to ascertain to what degree the physical appearance of a Brazilian
individual was predictive of genomic African ancestry. Using a panel of 10 population-…

Hydrogen is a clean energy alternative to fossil fuels. Photosynthetic bacteria produce hydrogen
from organic compounds by an anaerobic light-dependent electron transfer process. In …

We examined DNA polymorphisms in the nonrecombining portion of the Y-chromosome to
investigate the contribution of distinct patrilineages to the present-day white Brazilian …

Biological production of hydrogen can be carried out by photoautotrophic or photoheterotrophic
organisms. Here, the photosystems of both processes are described. The main …

Agriculture provides the largest share of food supplies and ensures a critical number of
ecosystem services (eg, food provisioning). Therefore, agriculture is vital for food security and …

This article presents a probability table for the evaluation of stress values generated by
multidimensional scaling (MDS) procedures employing stress formula 1. This table is based on …

Nannochloropsis is well appreciated in aquaculture due to its nutritional value and the
ability to produce valuable chemical compounds, such as pigments (zeaxanthin, astaxanthin…) …

Human facial diversity is substantial, complex, and largely scientifically unexplained. We used
spatially dense quasi-landmarks to measure face shape in population samples with mixed …

The inverse correlation between skin pigmentation and latitude observed in human populations
is thought to have been shaped by selective pressures favoring lighter skin to facilitate …

Variation in human skin and eye color is substantial and especially apparent in admixed
populations, yet the underlying genetic architecture is poorly understood because most genome…
