Rethinking water resources: Harnessing The Gambia River with pressure-driven membrane processes for sustainable supply.

The Gambia River is a tidal and tropical river that covers 12 % of the area of The Gambia and is to date not harnessed for drinking water supply purposes. Previous investigation on water quality indicated that the upper regions, with permanent and pristine freshwater, would be well suited for drinking water supply. With seawater intrusion, however, the downstream tidal and saline region is expanding further inland, requiring desalination technologies.

The levels of male gametic mitochondrial DNA are highly regulated in angiosperms with regard to mitochondrial inheritance.

The mechanisms that regulate mitochondrial inheritance are not yet clear, even though it is 100 years since the first description of non-Mendelian genetics. Here, we quantified the copy numbers of mitochondrial DNA (mtDNA) in the gametic cells of angiosperm species. We demonstrate that each egg cell from Arabidopsis thaliana, Antirrhinum majus, and Nicotiana tabacum possesses 59.

Segmentation and three-dimension reconstruction of Chinese digitized human cerebrum.

Objective: A 3D digitized visible model of human cerebrum was built to provide anatomical structure for making plans of cerebral surgical operation and realizing accurate simulation of cerebrum on computer.

Methods: Transverse sectional anatomy data of the cerebrum were chosen from the first Chinese visible human (one male and one female). Semi-automated segmentation and Photoshop software were selected to segment cerebral cortex, white matter, basal nuclei, lateral ventricle, hippocampus, etc.
