Study on arsenic removal process from water

In this study a novel adsorbent, iron oxide, is used for As (V) or As (III) removal. Some ferric oxides have been reported to be effective for arsenic removal. Ferric oxides powder is a good adsorbent material since it’s has magnetic properties and a good adsorption capacity. The main purpose of this study has been focused on to study the relationship between adsorption capacity (ability, performance) and the surface characteristics of the ferric oxide. Prepared sample’s capacity was evaluated. The value was 26.1-67.4 mg/g for As (V) and 20.5-47.8 mg/g for As (III). pH dependence was evaluated and when pH increasing, adsorption capacity was decreased. The kinetic was evaluated and about 12 hours reached equilibrium and a capacity of 49 mg/g for As (V) and 42 mg/g for As(III) was gained. The kinetic constants for arsenic adsorption on the ferrihydrite adsorbent’s were fitted.DOI: http://dx.doi.org/10.5564/mjc.v12i0.172 Mongolian Journal of Chemistry Vol.12 2011: 53-5

Toward a holistic understanding of pastoralism

Pastoralism is globally significant in social, environmental and economic terms. However, it experiences crises rooted in misconceptions and poor interdisciplinary understanding, while being largely overlooked in international sustainability forums and agendas. Here we propose a transdisciplinary research approach to understand pastoralist transitions using i) social, economic and environmental dimensions, ii) diverse geographic contexts and scales to capture emerging properties, allowing for cross-system comparisons, and iii) timescales from the distant past to the present. We provide specific guidelines to develop indicators for this approach, within a social-ecological resilience analytical framework to understand change. Distinct systems undergo similar transitions over time, crossing critical thresholds and then either collapsing or recovering. Such an integrated view of multidimensional interactions improves understanding of possible tipping points, thereby supporting better-informed decision-making. The need for a paradigm shift in pastoralism science and policy is pressing. This research approach, including participatory methods, can provide the solutions urgently needed.Peer reviewe

Mongolian and Japanese Joint Conference on "Echinococcosis: diagnosis, treatment and prevention in Mongolia" June 4, 2009

The first Mongolian-Japanese Joint Conference on "Echinococcosis: diagnosis, treatment and prevention in Mongolia" was held in Ulaanbaatar on June 4th, 2009. It was the first chance for Mongolian experts (clinicians, pathologists, parasitologists, biologists, epidemiologists, veterinarians and others working on echinococcosis) joined together. Increase in the number of cystic echinococcosis (CE) cases year by year was stressed. CE in children may be more than adult cases. Alveolar echinococcosis was suspected chronic malignant hepatic tumors or abscesses. Main discussion was as to how to introduce modern diagnostic tools for pre-surgical diagnosis, how to establish the national system for the data base of echinococcosis with the establishment of a network system by experts from different areas. The importance of molecular identification of the parasites in domestic and wild animals was also stressed
