Preparation Methods

In recent years, close attention has been paid to microbial flocculants because of their advantages, including safety to humans, environmental friendliness, and acceptable removal performances. In this review, the preparation methods of microbial flocculants were first reviewed. Then, the performances of bioflocculants in the removal of suspended solids, heavy metals, and other organic pollutants from various types of wastewater were described and commented, and the removal mechanisms, including adsorption bridging, charge neutralization, chemical reactions, and charge neutrality, were also discussed. The future research needs on microbial flocculants were also proposed. This review would lead to a better understanding of current status, challenges, and corresponding strategies on microbial flocculants and bioflocculation in wastewater treatment.

The Past

With global periglacial geomorphology undergoing significant advancements, it is appropriate to review the past and current status of such research in Africa. A brief historical overview of research outputs and approaches is presented for the respective African regions. Potential future quantitative periglacial research needs and approaches identified for Africa include: the examination of active periglacial processes, the identification of landforms and ground-ice forms, the potential for environmental change and the palaeoenvironmental reconstruction, and the application of periglacial studies. It is demonstrated that while periglacial geomorphology has progressed significantly in southern Africa, there has been little or no advancement elsewhere on the continent over the last two decades. None the less, on a more positive note, it is concluded that Africa has considerable potential in future global periglacial research.

AbstractAlthough the Fish Stocks Agreement was adopted by consensus after around only 2.5 years of negotiation, the final text did not fully resolve all significant differences of view. As it was feared that participation in the Fish Stocks Agreement would remain as troublesome as in the 1958 Geneva Fisheries Convention, considerable efforts have been made to promote wider participation since the Agreement’s entry into force in 2001. On 22 November 2010 there were 78 parties to the Fish Stocks Agreement and 161 to the Law of the Sea Convention. This article examines the current status and reasons for non-participation in the Fish Stocks Agreement by, inter alia, categorizing non-participation, appraising participation in light of the current participation in the Law of the Sea Convention and examining the relationship between the Agreement and regional fisheries management organizations.
