Sanitation assessment of wastewater treated by stabilization ponds for potential reuse in agricultural irrigation sanitation assessment

Wastewater reuse has become an important alternative to agricultural irrigation; on the other hand, it poses concern with regard to public health. Total coliform and Escherichia coli concentration, presence of helminth eggs and Salmonella, and physical-chemical parameters were evaluated in raw and treated wastewater. Chemical and biochemical oxygen demand removal efficiency was 74.6 and 77.9%, respectively. As for organic nitrogen, total phosphorus, and total suspended solids, total efficiency removal was 17.4, 12.5, and 32.9%, respectively. The average density of total coliforms and E. coli was 3.5 x 10(9) and 1.8 x 10(8) MPN/100 mL and 1.1 x 10(7) MPN/100 mL and 3.9 x 10(5) MPN/100 mL for raw and treated wastewater, respectively. Ascaris eggs were observed in 80.8% of the samples collected, and viable eggs in 42.3% of the samples. Salmonella was detected in 36.4% of the samples. The values observed in treated wastewater did not show the adequate bacteriological quality, as recommended by World Health Organization (Geneva, Switzerland). Therefore, additional measures should be taken to achieve an improved microbiological and parasitological quality.

CEFACT: an international private/public sector partnership

The Centre for the Facilitation of Procedures and Practices in Administration, Commerce and Transport (CEFACT) constitutes a partnership between the public and private sectors for their mutual benefit. For the private sector, working with governments to improve commerce is critical to improving international competitiveness. For governments, working with the private sector to reduce procedural barriers to trade is critical to improving both their own administrative effectiveness and the economic well-being of their countries. This issue of the Bulletin presents an exposition by the Chairman of the CEFACT, Mr. Henri Martre, at the Trade Facilitation Seminar, carried out between 9 and 10 March of 1998, at the Headquarters of the World Trade Organization, Geneva, Switzerland. Its main purpose is to explain the importance of CEFACT's partnership between the public and private sectors; how this partnership works, and the trade facilitation instruments it has created.

Use of autogenous bone and beta-tricalcium phosphate in maxillary sinus lifting: a prospective, randomized, volumetric computed tomography study

The correction of bone defects can be performed using autogenous or alloplastic materials, such as beta-tricalcium phosphate (β-TCP). This study compared the changes in bone volume (CBV) after maxillary sinus lifting using autogenous bone (n=12), autogenous bone associated with β-TCP 1:1 (ChronOS; DePuy Synthes, Paoli, CA, USA) (n=9), and β-TCP alone (n=11) as grafting material, by means of cone beam computed tomography (CBCT). CBV was evaluated by comparing CBCT scans obtained in the immediate postoperative period (5-7 days) and at 6 months postoperative in each group using OsiriX software (OsiriX Foundation, Geneva, Switzerland). The results showed an average resorption of 45.7±18.6% for the autogenous bone group, 43.8±18.4% for the autogenous bone+β-TCP group, and 38.3±16.6% for the β-TCP group. All bone substitute materials tested in this study presented satisfactory results for maxillary sinus lifting procedures regarding the maintenance of graft volume during the healing phase before the insertion of implants, as assessed by means of CBCT.

Bringing results to fruition through publication: An analysis of a peer-reviewed, open access and context-focused journal's editorial practice

When it comes to helping to shape sustainable development, research is most useful when it bridges the science–implementation/management gap and when it brings development specialists and researchers into a dialogue (Hurni et al. 2004); can a peer-reviewed journal contribute to this aim? In the classical system for validation and dissemination of scientific knowledge, journals focus on knowledge exchange within the academic community and do not specifically address a ‘life-world audience’. Within a North-South context, another knowledge divide is added: the peer review process excludes a large proportion of scientists from the South from participating in the production of scientific knowledge (Karlsson et al. 2007). Mountain Research and Development (MRD) is a journal whose mission is based on an editorial strategy to build the bridge between research and development and ensure that authors from the global South have access to knowledge production, ultimately with a view to supporting sustainable development in mountains. In doing so, MRD faces a number of challenges that we would like to discuss with the td-net community, after having presented our experience and strategy as editors of this journal. MRD was launched in 1981 by mountain researchers who wanted mountains to be included in the 1992 Rio process. In the late 1990s, MRD realized that the journal needed to go beyond addressing only the scientific community. It therefore launched a new section addressing a broader audience in 2000, with the aim of disseminating insights into, and recommendations for, the implementation of sustainable development in mountains. In 2006, we conducted a survey among MRD’s authors, reviewers, and readers (Wymann et al. 2007): respondents confirmed that MRD had succeeded in bridging the gap between research and development. But we realized that MRD could become an even more efficient tool for sustainability if development knowledge were validated: in 2009, we began submitting ‘development’ papers (‘transformation knowledge’) to external peer review of a kind different from the scientific-only peer review (for ‘systems knowledge’). At the same time, the journal became open access in order to increase the permeability between science and society, and ensure greater access for readers and authors in the South. We are currently rethinking our review process for development papers, with a view to creating more space for communication between science and society, and enhancing the co-production of knowledge (Roux 2008). Hopefully, these efforts will also contribute to the urgent debate on the ‘publication culture’ needed in transdisciplinary research (Kueffer et al. 2007).

Partnership Actions for Mitigating Syndromes (PAMS): Experience with a transdisciplinary tool in the NCCR North-South programme

Partnership Actions for Mitigating Syndromes (PAMS) are small transdisciplinary projects which bring scientific research insights from the NCCR North-South into policy and practice. They are implemented by researchers from different disciplines in collaboration with non-scientific actors. PAMS aim to implement and test approaches, methods and tools developed in research, in order to identify promising strategies and potentials for sustainable development. In this sense, they are solution-oriented. This paper will provide insights into our experience with PAMS, with a special focus on the implementation of transdisciplinarity and its outcomes. From 2001 to 2010, 77 PAMS were implemented in Africa, Asia and Latin America. An internal evaluation of the first 55 projects was conducted in 2006. Results of this evaluation led to a refinement and improvement of the tool. A second internal evaluation is currently underway in the NCCR North-South. This evaluation will provide an overview of 22 new PAMS. We will look at partners involved, project beneficiaries, activities implemented, outcomes achieved, and lessons learnt. In the first evaluation, transdisciplinarity was considered as “a form of collaboration within scientific fields … and as a form of continuous dialogue between research and society” (Messerli et al., 2007). The evaluation report concluded that this understanding of transdisciplinarity was not satisfactorily applied in the 55 projects. Only about half of the PAMS addressed mutual exchange between researchers and society. Some involved only one specific field of research and clearly lacked interdisciplinary co-operation, and most often knowledge was transferred mainly unilaterally from the scientific community to society, without society having any effect on science. It was therefore recommended to address transdisciplinarity more carefully in Phase 2 PAMS. The second evaluation, which is currently under way, is analysing whether and how this recommendation has been met, based on criteria defined in the NCCR North-South’s Outcome Monitoring Strategy. The analysis is focusing on partners with whom researchers interact and investigating whether practices have changed both in research and society. We are also exploring the role of researchers in PAMS. Preliminary results show that researchers can assume different roles, from direct implementation, mediation, and promotion of social learning between different actors, to giving advice as neutral outsiders.
