Optimisation of Electrokinetic Extraction System: Colourimetric Determination of Copper (II) in Sand Using Polymer Inclusion Membrane

ELECTROPHORESIS, EarlyView.
Electrokinetic extraction (EKE) allows the direct transfer of heavy metals from soli samples, such as soil and sediment, into a polymer inclusion membrane (PIM) with a colourimetric detection. This avoids length and complex sampling handling and extraction processes.

Studies on the method and its efficiency of extracting Bt toxic protein from Bt transgenic rice

浙江大学学报. 农业与生命科学版, 2001
Extractive efficiency of several extractants of Bt toxic protein from Bt transgenic rice was studied by orthogonal experiments. The results showed that the extractants and extracting conditions have similar efficiency for Bt toxic protein and the total ...

Genetically Engineered Nanobody–Recombinant Antibody Colloidal Gold Strip for Ultrasensitive Atrazine Detection in Fruits and Vegetables

Food Safety and Health, EarlyView.
A sensitive colloidal gold immunochromatographic assay for atrazine was successfully established using genetically engineered nanobody‐recombinant antibody, which overcame the shortcomings of traditional antigen‐antibody. ABSTRACT Colloidal gold immunochromatography (CG‐ICA) is distinguished by its cost‐effectiveness and rapid detection capabilities ...

Selecting Promising Soil Quality Indicators for Monitoring Soil Management Effects Based on 10 European Long‐Term Field Experiments

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Soil quality can be measured through soil quality indicators that reflect soil processes. Aim: The aim of this study was to (1) identify a limited set of soil quality indicators that are most sensitive to agricultural soil management and that are widely applicable regardless of pedo‐climatic conditions, and (2) link common ...

Establishment Limitations of Sensitive Target Species Potentilla alba L. in Grasslands Restored on Arable Land

Land Degradation &Development, EarlyView.
ABSTRACT Species in grasslands restored from former arable land have multiple obstacles when establishing. Understanding whether these limitations stem from soil chemical or microbial differences could help to create suitable environments for specific target and other species with similar requirements.

Long‐Term Straw Returning Combined With Mineral Fertilization Enhances Soil Quality but Elevates P Loss Risks in a Subtropical Rice–Wheat Rotation System, Central China

Land Degradation &Development, EarlyView.
ABSTRACT Long‐term straw returning is widely promoted to improve soil quality in intensive cropping systems, yet its combined effects with mineral fertilization on soil quality and phosphorus (P) loss risks remain unclear. Using a 16‐year field experiment in a rice–wheat rotation system, we evaluated the impacts of straw returning (S), NPK ...

Third molars: To extract or not to extract? [PDF]

Dental Press Journal of Orthodontics, 2015
showed that general dentists recommend extraction of third molars in 59% of patients, mainly to prevent future problems or because a third molar had an unfavorable orientation or was unlikely to erupt. However, the power to predict third molar eruption is low, and impacted third molars that remain static, with no changes in position or angu -lation ...
