The feasibility of using the bio-photonic imaging technique to assess symptoms of circular leaf spot (CLS) disease in Diospyros kaki (persimmon) leaf samples was investigated. Leaf samples were selected from persimmon plantations and were categorized into three groups: healthy leaf samples, infected leaf samples, and healthy-looking leaf samples from infected trees. Visually non-identifiable re...

This manuscript describes a new protocol for determination of Pa/Th/U in marine sediments. It is based on microwave-assisted digestion and represents an important reduction of working time over conventional hot-plate digestion methods, and the use of HClO(4) is avoided. Although Th and U are completely dissolved with a first microwave step, around 40% of (231)Pa remains undissolved, and a short...

This work addresses a fundamental drawback of conventional bio-signal acquisition interfaces by incorporating a reconfigurable analog front-end (AFE) that can be configured to always operate in an optimal power mode through digital assistance. Implemented in 65 nm CMOS, the AFE has tunable noise performance exhibiting an input-referred noise ranging from 1.90-2.91 while consuming 307-769 nW pow...

in this study, a bacterial species which could remove lead from wastewater was isolated from lead contaminated soil prepared in the laboratory. based on the biochemical and morphological characterization the bacteria were identified as brevundimonas vesicularis. the biosorption potentiel of powdered dry biomass of b. vesicularis was investigated by batch adsorption experiments. it was found tha...

Abstract Conventional methods for water and wastewater treatment are energy-intensive, notably at the stage of coagulation–flocculation, calling new strategies to predict pollutant reduction because amount energy consumed is related how much treated. Here we developed a model, named Bio-logic, inspired by ecosystems, where pollutants represent organisms, coagulants food, wider environmental con...
