speed of air movement and changes in the direction of air movement. It is common to find some differences between the original design and the final installation, as ductwork must share limited space with structural members and other“hidden”elements of the building system (e.g., electri...
The term ‘Corrosion’ means degradation of a material caused by chemical or electrochemical reaction with the environment. The material generally refers to metals but can also include non-metallic materials, such as ceramic, polymer and plastics. Corrosion not only affects the strength and durability...
Bioremediation makes use of plants/microorganisms to reduce the concentrations or toxic effects of metals and other inorganic pollutants in the environments. Bioremediation strategies usually include phytoextraction (or phytoaccumulation), phytofiltration, phytostabilization, phytovolatilization, phytodegradation, ...

However, like all new technologies, it comes with the question of degradation of the dye molecules and hence issues concerning with stability are raised (Bagher et al., 2015) (Fig. 5). Sign in to download full-size image Fig. 5. Dye-sensitized solar cell. The poor optical absorption of...
Additionally, the deposition of pollutants from the atmosphere on the stone surface can affect microbial colonization and degradation and may accelerate biodeterioration [2]. At present, we found no studies with atmospheric Nr deposition on microorganisms in stone monuments with different biodeterioration....
Alloysare compounds consisting of more than one metal. Adding other metals can affect the density, strength, fracture toughness, plastic deformation, electrical conductivity and environmental degradation. 合金是由一种以上金属组成的混合物。加一些其它金属能影响密度、强度、断裂韧性、塑性变形、导电性以及环境...
The soil contamination caused by heavy metals (HM) is a severe problem that reduces crop yields and negatively affects human and animal health2. The properties of HM make them non-biodegradable3. Therefore, HM remains intact in soil for a long time, necessitating discovering remediation methods ...

Use of products specifically designed to be robust against degradation in storage is also suggested. In repair/recommissioning situations, the generally prescribed treatment for atrophied aluminum electrolytic capacitors is to apply the system voltage gradually, over a period of 4-8 hours. Before so ...
