Waste stabilisation ponds are a widely accepted and proven technology to treat wastewater. It is often stipulated (and also practised) that the design of ponds for faecal sludges (FS), septage in particular, should follow the same principles as for wastewater. Field research conducted by SANDEC and its partners at the Water Research Institute in Ghana, and information gathered from the scarce literature on FS treatment, however, has shown that design principles should be taken into consideration, which are specific to the treatment of FS. These principles depend on the type of FS to be treated and on the type of pond system envisaged. Issues dealt with in this article are the handling of FS solids; the role of anaerobic ponds in FS treatment; the anaerobic degradability of septage; and ammonia (NH3–N) toxicity.

Using an instrument that was recently developed at the National Water Research Institute, the concentration of frazil in flowing water was measured under laboratory conditions for both fresh water and sea water and under natural conditions in the Beauharnois Canal. Experimental data and their analysis are reported in this paper.

AbstractAn international VLBI experiment on radio location of the asteroid 2012 DA14 was organized on 2013 February 15–16, during its flyby close to Earth. The purpose of observations was to investigate and specify orbital parameters of the asteroid, as well as to evaluate its rotation period and other characteristics. The irradiation of the asteroid was performed by the RT-70 transmitter at Evpatoria (Crimea, Ukraine), while the reflected signals were successfully accepted by the two 32 m radio telescopes at Medicina (Bologna, Italy) and Irbene (Ventspils, Latvia). Processing and interpretation of the data were performed both in the Radiophysical Research Institute at Nizhny Novgorod and in the Ventspils International Radio Astronomy Center. The first results of this experiment are presented and discussed.

A sizeable, and sometimes overwhelming, array of knowledge is available and relevant to Sustainable Water Management (SWM). This knowledge derives not only from the natural, social and engineering sciences but also from practical experiences in water management, which is defined broadly to include all forms of water use as well as the protection of water resources and reduction of risk from water‐related hazards. As a publically‐funded water research institute, Eawag (the Swiss Federal Institute of Aquatic Science and Technology) faces the challenges of integrating and synthesizing available knowledge, creating new knowledge through research projects and making knowledge available in an accessible form to support engineering practice, water resources management and related policy‐making. This chapter examines these challenges from an organizational perspective, discussing measures taken within Eawag to meet them and identifying remaining gaps and possible ways to address them.

In order to assess the usefulness of a computer based silvicultural information system, the Swiss Federal Research Institute WSL, developed and tested a prototype of such a system in collaboration with the forest enterprise Bremgarten (BWW). This work describes the prototype, built on a GIS-platform, and fed with a database which particularly takes small mixed stands into account. First results are interpreted with regard to the usefulness of such a system in practice.

First Results

My talk will be on the oblique rotator model which was first proposed by Stibbs (1950), and since received success and further developments. I shall present two different attempts at describing a star according to this model and the first results obtained in the framework of a Russian-French collaboration in order to test the precision of the two methods. The aim is to give the best possible representation of the element distributions on the Ap stellar surfaces. The first method is the mathematical formulation proposed by Deutsch (1958-1970) and applied by Deutsch (1958) to HD 125248, by Pyper (1969) to α2CVn and by Mégessier (1975) to 108 Aqr. The other one was proposed by Khokhlova (1974) and used by her group.
