In this paper He-discharge (plasma jet/bullet) in atmospheric pressure air and its progression phenomenon has been studied experimentally using ICCD camera, optical emission spectroscopy (OES) and calibrated dielectric probe measurements. The repetitive nanosecond pulse has applied to a plasma pencil to generate discharge in the helium gas channel. The discharge propagation speed was measured from the ICCD images. The axial electric field distribution in the plasma jet is inferred from the optical emission spectroscopic data and from the probe measurement. The correlation between the jet velocities, jet length with the pulse duration is established. It shows that the plasma jet is not isolated from the input voltage along its propagation path. The discharge propagation speed, the electron density and the local and average electric field distribution along the plasma jet axis predicted from the experimental results are in good agreement with the data predicted by numerical simulation of the streamer propagation presented in different literatures. The ionization phenomenon of the discharge predicts the key ionization parameters, such as speed, peak electric field in the front, and electron density. The maximum local electric field measured by OES is 95 kV/cm at 1.3 cm of the jet axis, and average EF measured by probe is 24 kV/cm at the same place of the jet. The average and local electron density estimated are in the order of 1011 cm-3 and it reaches to the maximum of 1012 cm -3. © 2013 Author(s).

Ultra wide band (UWB) impulse radio (IR) technology has different applications in different sectors such as short range radios and collision avoidance radar. A strong signal denoising method is needed for UWB-IR signal detection. One of the challenges of UWB-IR signal detection technique is the environmental interferences and noises. Wavelet Packet Transform (WPT) based multi-resolution analysis technique is suitable for this kind of signal denoising and detection. The paper describes a better method of denoising and detection technique of UWB-IR signal based on calculation of energies of the coefficients of each WPT terminal-node and by using an improved threshold calculation technique. The proposed technique is investigated through both simulation and experimentation. © 2010 EMW Publishing. All Rights Reserved.

Selenium occurs naturally in the environment and is toxic at elevated concentrations, which has been a challenging issue for environmental scientists. This work was devoted to the detection and removal the selenium (Se(IV)) from aqueous solutions using organic ligand an immobilized conjugate adsorbent. The organic ligand of (3-(3-(methoxycarbonyl) benzylidene)hydrazinyl) benzoic acid was synthesized and indirectly immobilized onto the mesoporous silica. The adsorbent was applied to detect and remove Se(IV) in aqueous solutions at optimum conditions. This adsorbent exhibited high surface area-to-volume ratios and pores were uniform nanostructures. The adsorbent permitted rapid Se(IV) capturing detectable by naked eye observation. The limit of detection was 2.02 μg/L by the proposed method of the conjugate adsorbent. The Se(IV) capture system was optimized by varying the parameters of contact time, pH, initial concentration, competing ions and elution operations. The pH effect played an important role and the solution pH ranging from 0.5 to 7.0 was investigated. The data confirmed that acidic pH enhanced the Se(IV) sorption on the conjugate adsorbent resulting in an increased sorption efficiency percentage of Se(IV) to >98% at pH 1.50. The data were also fitted to the Langmuir isotherm, and the maximum sorption capacity was 93.56 mg/g. The introduction of diverse ions was individually added to solution, and these had no significant effect on the Se(IV) sorption by the adsorbent. The 0.20 M NaOH was used an eluent in the elution operation, and the adsorbent was used in many cycles without loss of cage cavities. Therefore, the conjugate adsorbent has shown favorable capturing ability in water samples, and this could be used as efficient adsorbents in potential practical applications for Se(IV) detection and removal from wastewater. © 2014 Elsevier B.V.

The functionalized mesoporous silica based meso-adsorbent was developed for ultra-trace Cu(II) detection and removal from wastewater. The meso-adsorbent was fabricated by direct immobilization of N,N-bis(salicylidene)1,2-bis(2-aminophenylthio)ethane onto mesoporous silica monoliths. The calculated HOMO-LUMO small energy gap suggested that the electrons excitation according to the electron/energy transfer mechanism was evident in the intense of color complexation during selective detection and removal. The adsorbent was successfully applied in the determination and removal of Cu(II) ions in environmental samples. Therefore, the meso-adsorbent has been shown to have the potential to be used as an effective adsorbent for trace Cu(II) capturing from wastewater. © 2013 The Korean Society of Industrial and Engineering Chemistry.

A novel functionalized mesoporous silica based meso-adsorbent was prepared for simple, efficient and rapid determination, sorption and recovery of trace palladium(II) in wastewater. The meso-adsorbent was prepared by indirect immobilization of ((3-(3-(methoxycarbonyl)benzylidene)hydrazinyl)benzoic acid) onto the cage-pored mesoporous silica. The optimum conditions were measured as a function of solution acidity, contact time, ion selectivity and adsorption isotherms models. The data revealed that meso-adsorbent offered simple and one-step procedure without using high tech instruments. The determined detection limit and sorption capacity were 0.11 μg/L and 184.50 mg/g, respectively. The meso-adsorbent can be repeatedly recycled without deterioration of the unique mesostructures and maintaining the same functionality for detection/sorption operations in next uses. © 2014 The Korean Society of Industrial and Engineering Chemistry.

Purpose – The purpose of this paper is to assess the inherent adaptive capacities of multilevel flood management institutions in England that are necessary to espouse the concept of Ecosystem-based Adaptation (EbA). Design/methodology/approach – This paper is based on an extensive assessment of flood management literature including European and English flood management policies, strategies, regulations and reports. First, an assessment protocol was developed from systematic literature search and, second, multilevel flood management policies and organizations were evaluated. A qualitative scoring method was applied at the assessment stage. Findings – The protocol included 18 major assessment criteria under seven EbA principles. Application of the protocol showed that English national flood policies showed comparatively greater adaptive capacities than European- and local-level policies and local organizations. Specialized flood management policies such as Catchment Flood Management Policies at the local level and European Policies such as flood directives are among the lowest-scoring policy institutions. It was also identified that there is an emerging trend of stakeholder participation, catchment-based approach and knowledge-based adaptation planning at the national level which potentially can be the entry points of wider-scale EbA implementation. This paper recommends proactive roles of local executive organizations through improving institutional communication, consideration of catchment-scale planning with clear adaptation goals and valuing local knowledge base. Originality/value – The research is important to identify the institutional aspects of adaptive capacity that require attention for promoting alternative adaptation measures such as EbA. © 2016, © Emerald Group Publishing Limited.

Methods for Romanizing Bangla, or writing Bangla with the English alphabet were proposed half a century ago, but never gained popularity. Today, a new type of Romanized Bangla has emerged in mobile phone SMS, email, chatrooms, social networking websites, etc. Mobile phone SMS are widely used by individual users, phone operators, advertisers, the government, etc. In this study, about 500 - 1500 high-impact Romanized Bangla messages sent to wide audiences over about 4 years, were studied. In 2011 about 50% of Romanized Bangla words had converged to common and uniform spellings. In this study, the convergence to uniform spellings was seen to have increased to about 75 % of the words. Extrapolating from these trends, over the next three years, the convergence may rise to 85-90 % of words. Romanized spellings were found to be brief, for ease of typing with hand-held devices. English words were being rapidly absorbed into the Bangla language. As spellings converge further towards uniformity in the next few years. Romanized Bangla will become even easier to read and write, The common spellings also make it easier for computer softwares to recognize and convert Romanized Bangla to Bangla script. While it may not be possible or advisable to alter the convergence in the spelling trends, it may be possible to exert some force on the convergence with a spellchecker. Favorable spelling trends would make the Romanization consistent with pronunciations in English, making Bangla language more readily accessible by speakers of English. © 2014 IEEE.
