Main findings of the present paper conclude that industrial (product/ plant) safety, in its broadened sense, does embrace the gain/loss statistical data of a product's introductory versions and represents a trade–off function of its profits (resource renovation) and its losses (resources drain).
Damages due to user implementation follow a Statistical Process Control (SPC) which can be conventionally controlled within a tolerance field described by the Upper Control Limit (UCL) and the Lower Control Limit (LCL). 2.2 The FMEA Technique as Safety Assessment for Automobile In industrial engineering, FMEA is implemented to monitor the progressive improvement in a product's quality, or equivalently the progressive reduction in a product's imperfection (deficiency).
Thus, our analysis will rely mainly on data available at the end of this phase near year 1900. 2.3.2 Modeling of Disturbed Phase It starts near year 1900 (beginning of the 20th century).
Comparison of the two volumes indicates that the overall RPN shrinks to about 11% of its volume, reflecting proper actions taken with regard to reduction of CO emission in air.
1- In SPC technique, the lower control limit is considered as a standard target for expected future performance, and helps in monitoring the direct effects of product’s environmental safety. 2- Displaying of RPN in new graphical domains helps in monitoring the gradual changes in the direct effects of product’s environmental safety which focuses on the human discretion. 3- In Markov model, most aspects of the direct and indirect effect of a product become so controllable that a compromised state can be designed to balance both useful and harmful outcomes of a proposed product. 4- Markov model application is still systematic and straightforward when it is limited to only six categorized entities, and to assess direct, and indirect effects, and most aspects of the industrial safety (plant / product) for environmental systems, especially strategic industries. 5- The designer of a prospective mechanical product has to include similar safety instructions for the whole ECS to achieve a reduction

Indeed, as a consequence of low velocity impacts, intra-laminar damage as fiber and matrix cracking and inter-laminar damage, such as delamination, often take place concurrently, leading to significant reductions in terms of strength and stability for composite structure.
Delamination are the most dangerous failure mechanisms because they may propagate causing a substantial strength reduction of the whole structure up to the collapse.
In Figure 1 a sketch of panel section is shown, while in Table II data related to the impactor and to the material are reported.
Table II: Impactor and material data.

Twenty SEM micrographs, acquired at a magnification of 3000×, were taken into consideration to obtain relevant statistical data associated with these experiments.
The mean values and the standard deviations of obtained data were calculated.
In total, five samples were tested for each investigated condition, in order to obtain relevant amounts of data.
These data can hardly be compared, which may lead to confusing discussions and explanations.
The current results of fracture toughness measurements are in variance with the obtained data by Das et al. [15]; the main reason is that different experimental steel has been used for the investigations.

Changes in ash and protein content had no obvious rules, but the data analysis results showed that the effect of drugs on these indexes was significant.
The combination of the tremendous separation power of the CE with a convenient and disposable cartridge in SPE, allows the improvement of the CE sensitivity and the reduction of the limits of detection and quantification[1].This paper compared the changes in blank and treatment in the changes of nutritional index for cold conditions and drug residues in treatment, in order to get the rules of the change, laid a good foundation for the processing of fluoroquinolones residues in beef in the future.
SAR and DIF were very stable during this temperature, and the drugs had inhibitory effect on the bacteria, the bacteria had no decomposition effect to them, these lead to the drug residues had no rise or reduction in beef during the storage time.

Mathematical dependences (σpl -T i σpl - ἐ) and compression data were used to determine material constants.
Flow stress vs. deformation temperature and strain rate dependence σpl=f(,T) was determined based upon both literature equations and experimental data (Fig. 4 and 5).
Decreasing the value of strain rate from 4x10-4 to 10-4s-1 results in a 15% flow stress reduction.
Increase of deformation temperature was found to have a greater influence on the flow stress value reduction.

Abstract: Zhunzhong area Qingshui River group has top and bottom boundaries,which are not clear,and research on the evolution of the lack in sequence stratigraphic framework of deposition and on the reservoir sand body types do not have a clear understanding problem.In seismic interpretation, core description and based on the analysis of the related test,combining with the mud logging and well logging data,for the redefinition of Qingshui River group on the top and bottom boundaries,it identifies 6 time significance of sequence boundary,taking Qingshui River group can be divided into 2 sequences, 5 system tracts;clear and definite the study area
Figure 2 - North and south of Qingshui River group in the Zhunzhong area to the seismic reflection characteristics (2)Sequence characteristics of rock electricals Compared with the seismic data,logging data not only has higher vertical resolution,and analysis can be performed for all the wells formation,combined with the extraction of lithologic information logging, core and outcrop data,research on precise quantification and transverse comparison of stratum.At present electric Prorperties analysis has been widely applied in sequence stratigraphy and Sedimentology.[4] Based on the synthetic seismogram calibration method,The seismic information combining with logging, logging data,rock electrical feature recognition of each seismic sequence interface,in addition, the other two have the time significance of interface of FFS1 and FFS2
(3)Other features In addition to seismic sequence analysis characteristics and rock electrical sequence features,this paper,research of uses the time difference and wavelet mudstone acoustic spectrum analysis method and so on characteristics of sequence.[5] (4)Sequence stratigraphic framework Figure 3 In the Zhunzhong area of Qingshui River group of sequence stratigraphy Application of Vail sequence stratigraphy theory,the above various sequence features and regional geological data analysis,sequence stratigraphic framework in the Zhunzhong area of Qingshui River group[6].The Qingshui River group was divided into sequence 1 and sequence 2: Sequence 1 complete contains lowstand, transgressive systems tract and highstand of 3 system tracts,but the sequence SQ2 top highstand system tract denudation,contains only the lowstand and transgressive domain of two domain system (Figure 3) Knowledge of previous different,this research believes that the Qingshui River group in the bottom of
the Jurassic Cretaceous regional angular unconformity boundary marker,it identify the main application of seismic data truncation phenomenon,with the combination of well and seismic method to Identification;While the top by mudstone color from grey mutation to red brown to mark the boundary,to identify the main according to the well logging data, the upper part of the red mudstone layer under the Hutubi group.
(3)Semi deep lake subfacies Located below the normal wave base,the scope of the storm wave base,soil of weak reduction in hypoxia -reduction environment,sediment is mainly affected by the lake flow and storm wave action.The lithology of thick layer grayish black mudstone,containing a small amount of siltstone, developed horizontal bedding (Figure 4-i) and fine wavy bedding.fossil plankton rich,and the preservation of good, high organic matter content.Well logging curve is the main performance for the high gamma characteristics.

Other materials such as charcoal, electrode proposed use the data from Simapro software.
The inventory of industrial silicon production [11] instead of pure silicon was recommended because the data of pure silicon production is not available.
The emission factors of power plants were obtained from the data based on the situation of China [12].
The inventory data can be transferred to the corresponding environmental impact indicators based on CML method.
