extremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Surface gas-exchange processes of snow algae.
The red-colored chlorophyte Chlamydomonas nivalis is commonly found in summer snowfields. We used a modified Li-Cor gas-exchange system to investigate surface gas-exchange characteristics of snow colonized by this alga, finding rates of CO(2) uptake up to 0.3 micromol.m(-2).s(-1) in dense algal blooms. Experiments varying the irradiance resulted in light curves that resembled those of the leave...
متن کاملnitrate removal from drinking water by point of use ion exchange
background: a laboratory study was conducted to investigate the ability of a special type of strongly basic resin mp500ws for the removal of nitrate from different waters. methods: two different types of point-of-use (pou) devices containing an identical resin were used. mp500ws known as macro porous was used in pou devices for removal of high concentrations of nitrate and sulfate ions from wat...
متن کاملA novel MRI contrast agent synthesized by ion exchange method
Objective: In this study, the zeolite-coated iron oxide nanoparticles were evaluated as MRI contrast agent and effect of the nanocomposite synthesis method on MRI contrast was tested. Materials and Methods: Ion exchange method was used for synthesis of iron oxide-zeolite and the as prepared nanocomposite was characterized by XRD, FESEM and TEM. The nanocomposite toxicity in the cell culture, a...
متن کاملAn ion-exchange nanomembrane sensor for detection of nucleic acids using a surface charge inversion phenomenon.
We present a novel low-cost biosensor for rapid, sensitive and selective detection of nucleic acids based on an ionic diode feature of an anion exchange nanoporous membrane under DC bias. The ionic diode feature is associated with external surface charge inversion on the positively charged anion exchange nanomembrane upon hybridization of negatively charged nucleic acid molecules to single-stra...
