Independent University, Bangladesh or IUB is a private university in Bangladesh. Its permanent campus is in Bashundhara, Dhaka. The university was established in 1993 by the Private University Act, 1992.The middle flame in the IUB logo represents the synthesis of the eastern and western traditions. It also conveys the idea of purity. Wikipedia.

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.

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.

Purpose - The aim of this paper was to identify various institutional repository (IR) initiatives taken by Bangladeshi institutions, including identifying prospects, exploring strategies, and framing guideline for building IRs in Bangladesh. Design/methodology/approach - The paper is a general review and counts the development of IR practices in Bangladesh. Other secondary sources, such as research reports, articles and internet, are used. Discussions were also held with staff members of some other libraries, who intended to establish IR in their respective institutions. Data were collected from different institutions, currently practicing IRs in Bangladesh, through personal visit and website. Findings - The study explored the existing status of practicing IRs in Bangladesh and identified the trends at national and global level of IRs. Results showed that some institutions established their repositories in Bangladesh using DSpace, others used Greenstone and EPrints. Originality/value - This paper provides basic information for beginners and helps in planning to build IR in their respective organizations in Bangladesh.

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.
