Artificial intelligence modeling of cadmium(II) biosorption using rice straw
TL;DR: In this article, the effect of three factors, biosorbent dose BD (0.1 and 0.5 g/L), pH (2 and 7) and initial Cd2+ concentration X (10 and 100 mg/L) at two levels “low” and “high” was investigated at room temperature (25 ± 4 °C), contact time (2 h) and agitation rate (5 Hz).
Journal Article
Using Genetic Algorithm to Improve Information Retrieval Systems
TL;DR: A new fitness function for approximate information retrieval which is very fast and very flexible, than cosine similarity fitness function is presented.
Journal ArticleDOI
Phytoplankton and environmental variables as a water quality indicator for the beaches at Matrouh, south-eastern Mediterranean Sea, Egypt: an assessment
TL;DR: In this paper, a study was carried out to determine the water quality of the beaches at Matrouh, south-eastern Mediterranean Sea, Egypt, by studying environmental variables as well as phytoplankton abundance and community structure.
Journal ArticleDOI
Optimization of Cadmium (CD(2+)) removal from aqueous solutions by novel biosorbent.
TL;DR: Dead leaves of a common ornamental plant, Dracaena draca, was used as a biosorbent for the removal of Cadmium (Cd2+) from aqueous solutions using a full 23 factorial experimental design and showed that the most significant effect for Cd2+ biosorption was ascribed to (X).

Salma M. Khaled,Elizabeth Hughes,Daniel Bressington,Monica Zolezzi,Ahmed Radwan,Ashish Badnapurkar,Richard Gray +6 more
TL;DR: The distributions of various types of prevalence estimates of NPS use are described and the impact of different population groups and study-related and tempo-geographical variables on characteristics of these distributions over the period of 2010 to 2016 is explored.
