Fish In toxicity experiments, a group of yearling carps(4.5±0.75 cm long and 2.2±0.5 g weight)
were used to taken from aquafarm in Shijiazhuang and then cultivated for two weeks under the
same lab conditions in 90-L aquariums supplied with filtered tap water at 20±2°C and pH 6.8±0.2,
in order to reduce the burden of any pollution that could be present.

Abstract: Recycled aggregate concrete (RAC) is a kind of practical and economic material to reuse the great amount of construction and demolition wastes, which has received many discussions nowadays.
After a building fire, the material properties of concrete change due to high temperature conditions.
However, owing to the fact that the variation and distribution of temperature in a fire is complex, it is very difficult for different structures and materials at elevated temperature to obtain a theoretical correlation between mechanical behaviors and constitutive relations [1, 2].

These polymeric materials have superior mechanical, thermal and anticorrosive characteristics ideally suitable for adverse environmental conditions [3].
On the other hand, most of the coating materials are toxic and harmful to the environment [3].
As such, recycle waste materials or biomass in general, is a promising option for coating agents (chemicals).

Besides that, aluminium is much cheaper than materials commonly used in other popular battery designs, e.g. lithium.
Conventional metal elements (anode, cathode) replaced by human-friendly textile-based materials. 2.
An important novelty is the textile materials used, which replaces the conventional aluminium- and silver-containing materials, resulting in a human-friendly, flexible product.

Factors affecting the hardware products quality
For the quality of large number of hardware products, it mainly influences by three aspect factors, including the procurement factors, design factors, manufacturing and processing factors.Raw materials, some standard parts and external cooperation parts make up procurement factors.
Procurement factors consist of three two-level factors (raw materials, standard parts, and coordination parts).
