Lignocellulosic materials have been used as bioadsorbents for contaminants removal from industrial effluents due to their physical-chemical properties, renewable source, low-cost and efficiency that make them competitive commercial activated carbon. The objective of this work is develop an efficient low cost bioadsorbent reusing the cashew nut shell (Anarcadium accidentale L), CNS, metal ions (...

Computer In Computer’s January 2002 issue, Barry Boehm presented a fresh look at a set of software development methods often referred to as agile or extreme programming (“Get Ready for Agile Methods, with Care,” Jan. 2002, pp. 64-69). This favorable assessment by one of the software establishment’s leading lights prompted the latest of several e-mail dialogues between Boehm and software luminar...

The paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. This experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orth...

In a forthcoming book [Boehm-Turner, 2003], we have analyzed many organizations’ experiences with agile and disciplined methods, and have elaborated our previous characterization [Boehm, 2002] of the “home grounds” in which agile and disciplined methods have been most successful. This analysis has enabled us to determine five critical decision factors that organizations and projects can use to ...

A mesoporous activated carbon (MAC) was synthesized from waste tires rubber (WTR) via a one-step ZnCl2/FeCl3 activation route, and the typical sample implemented in eliminating Eriochrome Black-T (EBT) dye Cr(VI) their synthetic effluents. The impact of impregnation ratio ZnCl2/FeCl3, temperature, period optimized . best AC created at 750°C for 60 minutes using 2:1 ZnCl2/FeCl3:WTR ratio. This a...

As observed by Intrigila [16], there are hardly techniques available in the λ-calculus to prove that two λ-terms are not β-convertible. Techniques employing the usual Böhm Trees are inadequate when we deal with terms having the same Böhm Tree (BT). This is the case in particular for fixed point combinators, as they all have the same BT. Another interesting equation, whose consideration was sugg...
