Risk genes for Mendelian (single-gene) disorders (SGDs) are consistent across populations, but pathogenic risk variants that cause SGDs are typically population-private. The goal was to develop "QChip1," an inexpensive ...
Study of performance, combustion, and emissions parameters of DI-diesel engine fueled with algae biodiesel/diesel/n-pentane blends
(
Elsevier Ltd
, 2021 , Article)
Biodiesel extracted from Scenedesmus obliquus algae through transesterification was used in the current study. Due to the disadvantages of using pure biodiesel in engines, it was used as B50 (a blend of 50% diesel and 50% ...
Treatment of wastewaters by microalgae and the potential applications of the produced biomass-a review
(
MDPI AG
, 2021 , Article)
The treatment of different types of wastewater by physicochemical or biological (nonmicroalgal) methods could often be either inefficient or energy-intensive. Microalgae are ubiquitous microscopic organisms, which thrive ...
