Materials and methods Soil samples were collected in the Yellow River Delta National Nature Reserve in May 2007 in order to analyze the regional variation of nitrogen and phosphorus distribution characteristics in wetland soils.
Quality assurance and quality control were assessed using duplicates, method blanks and standard reference materials (GBW07401) obtained from the Chinese Academy of Measurement Sciences and the recovery rate of phosphorus was 108%.

The use of biopolymers or natural polymers as raw materials in the medical world is not new.
Therefore, additional materials are needed to make kappa carrageenan have water-resistant properties.
The starting materials were food-grade kappa carrageenan and Food-grade chitosan from crab shells produced by CV.

Experimental Investigations on Capabilities of Resistance Spot Welding and MIG Brazing for Producing Corrugated Beams Using Galvanized Steel Sheets RADU Bogdan1,a*, UNGUREANU Viorel2,3,b, BOTH Ioan2,c, BURCĂ Mircea1,d, BENZAR Stefan2,e, DUBINĂ Dan2,3,f 1University Politehnica Timisoara, Department of Materials Science and Engineering, Timisoara 300222, bd.
This paper summarized the research work carried out by a team from Department of Steel Structures and Structural Mechanics, together with Department of Materials Science and Engineering, from University Politehnica Timisoara, which tried to determine the possibility to use welding for obtaining built-up cold-formed steel beams made of corrugated galvanized steel sheets (grade S350GD+Z).
However, the main advantage of MIG brazing is the low temperature developed in the electric arc, which is lower than the fusing temperature of the base materials (galvanized steel grade S350GD+Z used in our investigations), the filler material, by capillarity fills the gap between the base materials and creates the brazed joint.
There were a very small number of samples the fail by an interfacial fracture between the two materials.
