Different materials have been studied for the manufacture of BPPs, ranging from graphite and graphite-based composites to metallic materials.
There are metallic materials as aluminum or stainless steel, which also presents another problems such as higher surface corrosion or membrane poisoning, so there is not a key material which is clearly the best option [6].
This equipment is employed in research activities for the development of standard and novel metallic materials.

The toxic metals originate from the mined out sulphide ore veins hosted in Miocene age andesite rocks. 1-3 pH leachate is being produced around the waste rock heaps due to the complex chemical and biological oxidation of the pyrite containing material in contact with the rainwater and runoff.
Given the topography (steep slopes), hydrogeology (high infiltration rate) and geology of the area and the site-specific processes due to the mineralogical composition of the ore, mine waste material and country rock (leaching, bioleaching, partition) the runoff water is the main pollution pathway in the conceptual risk model, and to a lesser extent the pore water.
Leaching of metals from pollution sources and the characteristic parameters of the process were given based on a complex (physical-chemical-biological) leaching test using the mine waste material from the area.
The key parameters of the risk were determined: the rate of acidification and metal mobilisation and the metal concentration of the emitted leachate.

Use the Conception of Universal Design to Instruct Housing Construction Hong CAO College of Civil Engineer and Architecture, Guangxi University，Nanning, China E-mail:redfreebird@sohu.com Key words: universal design, housing construction, barrier-free, universal house Abstract.
Units of universal houses can be adjusted or modified without re-building or changing the structure and citizens can, based on utilization requirements, finish some simple non-structure adaptable reformations by themselves, such as conducting reformations of “adapting to the aged” by stage on the interior space, structure, facilities and equipments considering the physiological need that the aged are changing all the time, including changing the interior discrepancy in elevation into slopes, laying anti-skid materials on the ground, enlarging the width of door frameworks, lowering the height of washing counters, removing the wall cabinets so that the basin in the kitchen and bathroom can accommodate knees, arranging handrails in where it is required on the wall and setting up the emergency alarm system, etc.
Therefore, the conception of promoting universal houses is put forward: the State or enterprises build some material houses, track and investigate residents’ utilization status, compare the utilization effect, current issues and social benefits with those of common houses, test the feasibility and superiority of universal houses and further promote and popularize them.

One of the key techniques to probe these properties is positron annihilation lifetime spectroscopy (PALS), which provides valuable information about the electronic structure and open-volume defects in materials [1, 2].
Calculation of positron lifetimes in bulk materials.

EXPERIMENTAL PROGRAM 2.1 Instrumentation X-ray diffraction (XRD) model PW1877, Infra-red spectrophotometer (FT.IR) model 8300, Thermo gravimetric Analyzer (TGA), Melting point measurement model M.F B 600-010 F as well as other normal laboratory equipment and glassware were used. 2.2 Materials The phenolic resin (novalac) prepared in the laboratory, was used as a source of carbon for graphitization process.
Beyond these regions, the pyrolysis of the materials continued with slower rate and lose in weight are stopped, which tends to saturate in temperature range between 625-1000oC for the resins BMR and NMR, being in the temperature more than 1000oC for resin (NR).
Beyond these temperature, the pyrolysis and the weight loss of the materials continued slowly.
