Geological disaster hazards are extremely serious, a great loss, according to the latest natural disasters statistics of the United Nations International Strategy for Disaster Reduction (UNISDR) and the Disaster Research on the Epidemiology Center (CRED) released in Geneva on January 28, 2010, between the years 2000-2009 ,3852 disaster events occurred in the world between the years 2000-2009, more than 78 million people were killed, and all kinds of material losses of up to $ 960 billion, which the earthquake led to the casualties up to the first major disaster threat.
Investigation appraisal method bases on the survey, according to some intrinsic link or trends between the disaster data, to infer the loss of the year which is no quantitative data.
Geological Disasters Indirect Economic Loss Assessment The indirect economic geological disasters loss includes stop and reduction production loss and associated loss.
Stop and reduction production losses can not be quickly restored production to get rid of the post-disaster economic "shock" state [2]; associated loss refers to it can’t quickly adjust the layout and get rid of the production capacity disequilibrium [2] which caused by disasters.

The recorded and calculated data of the test series are evaluated in a software application for data analysis and graphical representation and then displayed graphically.
By reducing the curing pressure from 5 bar to 1 bar, it is possible to save 87 kWh of energy, which corresponds to a reduction of 36 %.
Fig. 7: Energy saving potential by reducing the curing temperature It can be clearly seen that at a curing pressure of 1 bar a reduction of 71 % in energy consumption can be achieved by lowering the curing temperature from 180 °C to 80 °C.
However, since low-curing matrix systems require longer holding phases, the advantage lies in the reduction of the temperature and longer holding phases.

The results obtained by these electrochemical methods and the application of a complex body specimens may provide available data for evaluating the corrosion properties of the embedded steel bars.
Furthermore, the complex body specimen may serve as good reference data in the design and for successful maintenance of the concrete structures in marine environments.
Generally, the cathodic polarization curve measured in neutral seawater solution would exhibit nearly concentration polarization caused by reduction reaction of dissolved oxygen(O2 + 2H2O+ 4e→4OH-), thus, diffusion limiting current density would vary with thickness of diffusion layer.
However, dissolved oxygen, water and chloride ion penetrate continuously from surface of the specimen to embedded steel bar, and anodic oxidation reaction (Fe → Fe2++ 2e)by chloride ion and reduction reaction(O2 + 2H2O+ 4e→4OH-)by water and dissolved oxygen would happen on the surface of the embedded steel bar during immersed for long years.
However, during drawing of the cathodic polarization curve, the reduction reaction(O2 + 2H2O+ 4e→4OH-)by water and dissolved oxygen would only happen on the surface of the embedded steel bar.

Current statistical data indicate that 25% of the arable land in the world is now affected by high levels of water stress (Jajarmi, 2009), which causes more than 50% losses of the crop yields (Wang et al., 2003).
Numbers of seeds germinated are counted daily and data are recorded for 7 days.
However, drought stress causes the reduction of GI (Fig 1b), suggesting that germination of the weedy rice and cultivated rice is delayed due to the restriction of water uptakes.
Effects of drought on shoot length and the longest root length Drought stress causes the significant reduction of shoot growth in all of the germinated seeds comparing to no stress treatment (Fig 2a).
Drought stress also causes the reduction of root growth.

(c) Bending data recorded for non-PDMS covered sensors.
Raman data showing the mapping sample points and relevant peak position, D/G and 2D/G ratios.
Further reduction of the radius of curvature (more prominent for the case of 10 mm) is proved here to produce the opposite behaviour, i.e. an increase of the DR/R0 due to the lateral stretching of the GRF structure causing the destruction of some conductive paths.
The study shows a large hysteresis effect for the first cycles, and a reduction of the hysteresis loop area for the last cycles of the characterisation.
It is worth noting that the GRF structure used in this work as sensing element consists of few graphene layers (as demonstrated by Raman spectroscopy) which is a drastic reduction of the number of layers compared those standard works reported in the literature which has an impact on the resulting sensitivity.

IR reflection spectra were measured on a Bruker Equinox 50S Fourier-transform IR spectrometer with a MIRacle single reflection horizontal ATR attachment, using a ZnSe crystal, over the range 400-4000 cm-1 ; data of 500 scans were collected with a scanning step size of 2 cm-1 .
For a membrane treated for 60 s only insignificant reduction of the pore diameter being observed.
For the membrane treated for 300 s, the pore diameter reduction is quite essential and the thickness of the deposited polymer layer is about 400 nm.

This effect is connected with reduction of pH solution at the surface of this layer due to occurrence of a gradient of concentration of H + ions and protonation of sulfur atoms.

The main processes in RBF involved in pollution level reduction are dispersion, physical filtration, biodegradation, ion exchange, adsorption, and dilution [6-7].
This information can be utilized as baseline data for an alternative water treatment process that involves a natural filtration process, such as RBF.
The reduction in these parameters was influenced by aerobic, anoxic, and anaerobic processes in groundwater as explained by [14].
Besides that, [16] also suggested that water will have a high concentration of Fe during reduction condition if the local environment produces iron oxide (FeO) or iron hydroxide (Fe[OH]).
Additionally, this data can be used as a guide to propose a suitable and cost effective treatment process (e.g. aeration and adsorption by low cost media) for removing metal in production well.

Conductive polymers may undergo oxidation-reduction reaction which cause them to lose or gain electrons from the surrounding environment.
The corrosion resistance data derived from Fig. 4b were collected in Table 1.
