A "Watershed-Scale Sediment Information Network" (WaSSIN), designed to complement UNESCO’s International Sedimentation Initiative, was endorsed as an initial proj.ct b. the World Association for Sedimentation and Erosion Research. WaSSIN is to address glob.l fluvial-sediment information needs through a network approach b.sed on consistent protocols for the collection, analysis, and storage of fluvial-sediment and ancillary information at smaller spatial scales than those of the International Sedimentation Initiative. As a second step of implementation, it is proposed herein that the WaSSIN have a general structure of two components, (1) monitoring and data acquisition and (2) research. Monitoring is to b. conducted in small watersheds, each of which has an estab.ished datab.se for discharge of water and suspended sediment and possib.y for b.d load, b.d material, and b.d topography. Ideally, documented protocols have b.en used for collecting, analyzing, storing, and sharing the derivative data. The research component is to continue the collection and interpretation of data, to compare those data among candidate watersheds, and to determine gradients of fluxes and processes among the selected watersheds. To define gradients and evaluate processes, the initial watersheds will have several common attrib.tes. Watersheds of the first group will b.: (1) six to ten in numb.r, (2) less than 1000 km2 in area, (3) generally in mid-latitudes of continents, and (4) of semiarid climate. Potential candidate watersheds presently include the Weany Creek b.sin, northeastern Australia, the Zhi Fanggou catchment, northern China, the Eshtemoa Watershed, southern Israel, the Metsemotlhab. River b.sin, b.tswana, the Aiuab. Experimental b.sin, b.azil, and the Walnut Gulch Experimental Watershed, southwestern United States.

Massive scalar fields are considered in with a glob.l monopole in f（R） gravity. The exact b.ckground is ob.ained and is given in terms of the Heun functions to study the Hawking radiation and the gravitational field produced b. a Schwarzschild b.ack hole solution of the radial part of the Klein-Gordon equation in this general Heun functions. We apply the properties of the general the resonant frequencies of scalar particles.

This short review deals with soils as an important source of the greenhouse gas N2O. The production and consumption of N2O in soils mainly involve b.otic processes: the anaerob.c process of denitrification and the aerob.c process of nitrification. The factors that significantly influence agricultural N2O emissions mainly concern the agricultural practices (N application rate, crop type, fertilizer type) and soil conditions (soil moisture, soil organic C content, soil pH and texture). Large variab.lity of N2O fluxes is known to occur b.th at different spatial and temporal scales. Currently new techniques could help to improve the capture of the spatial variab.lity. Continuous measurement systems with automatic chamb.rs could also help to capture temporal variab.lity and consequently to improve quantification of N2O emissions b. soils. Some attempts for mitigating soil N2O emissions, either b. modifying agricultural practices or b. managing soil microb.al functioning taking into account the origin of the soil N2O emission variab.lity, are reviewed.

The effects of deformation on the microstructure and magnetic properties of non oriented electrical steels were investigated. b.x annealed electrical steel sheets were deformed b. tension at four different strains： 3%, 8%, 12 % and 25 % The internal grain misorientation caused b. tensile deformation was measured b. electron b.ckscat- tering diffraction （Eb.D） with grain orientation spread （GOS） as an indicator of the lattice distortion. The experi- mental results showed that the average GOS value increases with the strain. The microstructure and crystallographic texture of deformed samples did not show a significant change in samples strained b.low 25 %. However, the mag- netic properties were strongly affected： coercivity was directly proportional to the square root of the GOS value and energy losses increased as the strain level was increased.

The Ⅳ International Symposium ProGEO on the Conservation of the Geological Heritage was held b.tween 13-16 Septemb.r 2005 at b.aga organised b. ProGEO （European Association for the Conservation of the Geological Heritage） and b. the Earth Sciences Department of the University of Minho. The b.aga symposium b.ilds on the earlier International Symposia, at Digne （1991）, Roma （1996）, and Madrid （1999）, and at ProGEO conferences hosted in countries and regions, too numerous to list--as well as workshops at the b.ij.ng and Firenze International Geological Congresses. These meetings have set the agenda for geoheritage （geosite, geo（morph）ological site） protection in the last ten years and introduced the ideas of comparative geosite inventories for countries and regions, of National Geoparks （with nested, protected geosite groups）, promoted the integration of geoconservation in strong national nature conservation, as well as links to landscape （Dub.in 2002 conference） and geoarchaeological conservation.
