TL;DR: In this paper, an eggshell waste-derived hydroxyapatite was used to remove fluoride from aqueous solution, and the results indicated that the preparation may be an alternative source for defluoridation in developing countries.
Abstract: Fluoride has become a notable toxicological environmental hazard worldwide because it is often found in groundwater. In the present study, hydroxyapatite adsorbent was synthesized from eggshell waste to remove fluoride from aqueous solution. XRD, FT-IR, and TGA techniques were used to characterize the prepared adsorbent. Batch adsorption studies were performed to examine the adsorption capacity of hydroxyapatite such as the effect of the initial pH of the solution, contact time, adsorbent dose, and initial fluoride concentration. The fluoride ion-selective electrode was used to determine the fluoride removal efficiency. 98.8% of fluoride was removed at pH 3.0, but at pH ~7.0, 85% of fluoride was removed; it shows that the fluoride adsorption is pH dependent. The adsorption isotherm studies (Langmuir and Freundlich models) and the experimental results for the removal of fluoride showed that the Langmuir model was more favorable and the reaction followed pseudo-second-order kinetics. In real water samples, the prepared hydroxyapatite derived from eggshell exhibited 81% removal efficiency. Our results indicate that eggshell waste-derived hydroxyapatite may be an alternative source for defluoridation in developing countries.

01 Sep 2016TL;DR: In this article, the formability of different metal sheets using deep drawing process is evaluated for cylindrical cups using three levels of previously mentioned numerical simulations, and the results show that the shape formability for different metal sheet is observed for angular geometries of deep drawing tools.
Abstract: Deep drawing process is a significant metal forming process used in the sheet metal forming operations. From this process, complex shapes can be manufactured with fewer defects. Deep drawing process has different effectible process parameters from which an optimum level of parameters can be identified so that an efficient final product with required mechanical properties will be obtained. The present work is to evaluate the formability of different metal sheets using deep drawing process. In which effects of different sheets and die/blank holder angle on deep drawing process observed for sheet metal of 0.8mm of SS304 and Brass and 0.9 mm of Al. The experiments were performed by designing the deep drawing tools such as die, blank holder, and punch. In addition, the numerical simulations are performed for deep drawing of cylindrical cups using three levels of previously mentioned. Punch forces and dome heights are evaluated for all the conditions. From this work, the formability for different metal sheets is observed for angular geometries of deep drawing tools. Moreover, it is observed that strain formation is more for the brass sheet and stress is more for aluminium sheets.

TL;DR: In this paper, the authors present the willingness of local, public and private institutions to enter into partnership to participate in a specific deployment of a project perceived to be beneficial for low literate learners in their communities.
Abstract: Ensuring the success of deployment initiatives of specific programs in developing countries comes with the commitment of local, public and private institutions. Scientific Animations Without Borders (SAWBO) creates educational content for low literate learners, in their own local languages that can be deployed on video capable devices by in country groups. In other words, SAWBO creates content, for local communities of practice to use in their educational programs. Although SAWBO creates and deploys this content virtually, it is the domain of local groups to develop strategies and approaches for local and meaningful impact. Establishing partnership between local stakeholders, public and private institutions bring new opportunities to the deployment of educational materials in developing nations. In regards to this statement, the consultative group on a project entitled “Promotion and Pilot Deployment of Educational Materials for Low Literate Learners around Adama” offers a case study in commitment between participants. This paper explains the opportunities for, and challenges to, creating a community of practice and making decisions between public and private institutions leading to the deployment of educational materials in a form of animated videos around Adama City in the region of Oromia, Ethiopia. This paper presents the willingness of local, public and private institutions to enter into partnership to participate in a specific deployment of a project perceived to be beneficial for low literate learners in their communities. The report of the consultative meeting suggests that while initiatives and perceptions may differ among the different groups involved in the deployment, common goals facilitate the decision making to move forward. This paper is part of an ongoing effort to develop community of practice models, for deployment of cross-culturally adaptable educational animations, with the intent of reproducing similar approaches in other regions of the world.
