Due to the strong cation-exchange ability of Nafion and the excellent properties of multi-walled carbon nanotubes (MWCNTs), a highly sensitive and mercury-free method of determining trace levels of In(3+) has been established based on the bifunctionality of a MWCNTs/Nafion modified glassy carbon electrode (GCE). The MWCNTs/Nafion modified GCE detects In(3+) in a 0.01 M HAc-NaAc buffer solution ...

Mercury-thin film electrodes coated with a thin film of poly(ester sulphonic acid) (PESA) have been investigated for application in the analysis of trace heavy metals by square wave anodic stripping voltammetry using the batch injection analysis (BIA) technique. Different polymer dispersion concentrations in water/acetone mixed solvent are investigated and are characterised by electrochemical i...

Foul condensates from the digesters and evaporators contain reduced sulfur gas and organic compounds, such as methanol (MeOH) and turpentine, which contribute greatly to pulp mill water pollution in the form of Biochemical Oxygen Demand (BOD) and toxicity, and air pollution in the form of Volatile Organic Compounds (VOC), and odor. For this reason, foul condensates are collected and treated by ...

Brain is the part of the central nervous system located in skull. For the diagnosis of human brain bearing tumour, skull stripping plays an important pre-processing role. Skull stripping is the process separating brain and non-brain tissues of the head which is the critical processing step in the analysis of neuroimaging data. Though various algorithms have been proposed to address this problem...

Proton beam writing (PBW) is a new direct-writing process that uses a focused beam of MeV protons to pattern resist material at nano dimensions. PBW has the unique ability to maintain a straight path through 50 lm thick resist films, and is suitable for high aspect ratio micro(nano)-machining. TADEP resist is a new promising high aspect ratio chemically-amplified resist that can be developed in...

Chronic neurodegenerative diseases of the CNS (central nervous system) are characterized by the loss of neurons. There is, however, growing evidence to show that an early stage of this process involves degeneration of presynaptic terminals prior to the loss of the cell body. Synaptic plasticity in CNS pathology has been associated with microglia and the phenomenon of synaptic stripping. We revi...

Skull stripping is the first step in many neuroimaging analyses and its success is critical to all subsequent processing. Methods exist to skull strip brain images without gross deformities, such as those affected by Alzheimer's and Huntington's disease. However, there are no techniques for extracting brains affected by diseases that significantly disturb normal anatomy. Glioblastoma multiforme...

A selective and sensitive stripping voltammetric method for the determination of trace amounts of copper(II) with cyclopentanone thiosemicarbazone (CPTSC) is presented. The method is based on the adsorptive accumulation of the resulting copper-CPTSC complex on a hanging mercury drop electrode, followed by the stripping voltammetric measurements at the reduction current of the adsorbed complex a...

Theories of spoken word-recognition differ in the claims they make about continuous and discontinuous mapping of the speech input onto mental representations of lexical form. The research reported here contrasts the claims of a discontinuous, prefix-stripping model, and of a cohort-based continuous access model. In three experiments, using the gating, auditory lexical decision, and auditory nam...

effect of temperature on the duration of post ovulated oocyte quality maintenance in abdominal cavity of female rainbow trout, oncorhynchus mykiss, was assessed to determine suitable time of stripping. egg quality measurement was done through assessing the eying and hatching rates of eggs. regarding the best temperature range reported for salmonid brood fish in breeding season(3-10?c)the study ...
