The disease affects key rice growing areas in Malaysia and causes mild to serious infection to the crops.
Numerous studies have demonstrated that nano-inorganic materials elevated higher antibacterial activities compared to inorganic materials [1].
Among inorganic materials, ZnO nanoparticles (ZnO-NP) are of particular interest due to their nanostructure diversity and biotechnological applications [2].
The size of nanoparticles plays an important part in the interaction of materials with biological systems.

Abstract.
Dam heel stress is a key control indicator for arch dams.
Inversion analysis should also be conducted on the thermal parameters of the actual performance of dam concrete according to the measured air temperature, water temperature, sun exposure, other boundary conditions, and the thermal parameters of concrete materials obtained in material tests.

aqingkongyu@126.com,bjzzhao@xsyu.edu.cn, c329884575@qq.com Key words: CBM; gas content; folds, faults, tectonic characteristics Abstract:There are several geological factors affecting the accumulation of CBM, including tectonic condition, burial depth, coal thickness, coal rank, gas content, permeability, reservoir pressure, desorption pressure and hydrological condition, etc.
In material mechanics, when a beam of internal uniform structure bends under the horizontal extrusion, the distribution of stress in the beam differs obviously, there is a surface of no strain, which is called the neutral plane,neither extended nor shortened, however, the upper of which extends because of tension, while the lower of which shortens because of compression[5].

Abstract With the deepening of urbanization, the urban water environment is dramatically changed.
Traditional rainwater collection and reuse measures prefer the engineering measures, rather than ecological measures.
Total Annual Design Case Water Usage = Flush Fixture Annual Water Usage [gal] + Other Fixtures Annual Water Usage [gal] (7) Economic and environmental benefits analysis Costs of all material, equipment needed for installing rainwater systems were obtained from local stores, and the spending for treatment structures is estimated by local budget quota.
