This fibre reduction causes a high decrease of composite stiffness and strength [4,5].
Generally models are unsuitable to predict accurately the experimental data.
The residual humidity is less than 1% (supplier data).
Finally, the composite strength calculations give better accuracy with the experimental data (Fig.2).
Mechanical properties and elastic models confrontation Fig.4: Young’s modulus estimation from Halpin model in comparison with experimental data and matrix modulus value adjustment The Young’s modulus calculations from Halpin-Tsai model presented in figure 4 give an overestimation of 25 to 98% according to composite fibre contents.

Experimental investigations are useful in providing data and information for the design stage and improvement of classification rules and safety of the large ships at sea.
The fast Fourier transform (FFT) was adopted in this paper to transform the measured time domain data into the frequency domain.
The statistical significant amplitude values from the model test data were calculated by the spectral method and are presented in this part.
Therefore non-linear load events, such as slamming and whipping, need to be considered when processing load data for a ship sailing in rough seas.
Therefore, in the future work, non-linear data processing methods will be employed to deal with analysis of the load data, especially for high sea states.

The analysis and calculations are carried out in relation to the project for the construction of a mechanical vector in the town of Vietri sul Mare in the province of Salerno (Italy), which is useful in ensuring the decongestion of road traffic and the consequent reduction in travel times along the Amalfi Coast.
Cross-section of the project From the topographic and geotechnical characteristics of the intervention, depending on the height difference and technical data that characterise the different types of lifts, also through comparisons with lift manufacturers, there is the opportunity to make use of combined lifts with an electric ECO power system.
Data from the Provincial Tourist Board and the State Railway give the number of tourists visiting Vietri via train, with 207,773 users.
The input data required to activate the SAM Campania is the investment cost in the construction sector for the realization of the mechanical vector.
The logical path defined, from the real data to numerical calculations using methods of economic analysis, is an evaluative practice that can also be applied to project initiatives in other sectors.

Microvascular complications of diabetes are characterized by damage to the microvasculature of the kidney,retina and neurons[6].Reduction in retinal perfusion lead to vaso-occlusion and thus linked to the progressive ischaemic hypoxia[7].Ischemia is the key factor of diabetic retinopathy[8].Increased biomarkers of CRP,IL-6, and TNFalpha, and especially interstitial cellular adhesion molecule-1,vascular cellular adhesion molecule-1,and E-selectin are predictors of diabetic[9].
The increasing of tHcy concentrations lead to cardiovascular disease (CVD)[11-12].Plasma tHcy increase in patients with type II diabetes contributes to diabetic macroangiopathy)[13-14] tHcy maybe a biomarker of Diabetic retinopathy.From our datas,the levels of FA dicreased copared to control group.The levels of TG, Ch, HDL-C, LDL-C showed no difference between the two groups.This result was not consistant with what we anticipated.This may manifested that tHcy level will be a special and certain biomarker in the pathology process of Diabetic retinopathy.FA and vitamin B12 supplementation decreases homocysteine (tHcy) levels[15].So the supplementation of FA will be considered in the treatment of diabetic retinopathy process .HPLC is a chromatographic technique identifying the individual components of mixture.and the sample mixture is separated into compounds as it interacts with the column particles.This method is propriate for the tHcy detection in our research.
From our data, the increase of plasma tHcy maybe a risk factor in the occurrence of Diabetic retinopathy.HPLC can be useful for tHcy examination.

Demographic projections-urban growth
According to the World Population Data Sheet realized by Population Reference Bureau in Washington DC, 53% of the world's population lives in urban settlements.
The population is growing exponentially, together with the reduction of natural resources and environmental degradation.

Some examples are
discussed and illustrated with data for a copper-nickel sulfide ore.
A consequence of precipitation is the reduction in ferric ion concentrations available to react with sulfide minerals to form the ferrous ions required for continued bacterial growth.

Subsequent articles discuss the two models of the life cycle costs in delayed coking process which using the actual refinery instance data.
Therefore, it has practical significance to link the ecological problems with the main product of refinery system so as to seek solutions and take corresponding measures to realize energy saving and emission reduction.

Based on the test data, we suggested the temperature profile model to predict the slab temperature.
The data given in Table 1 were obtained using the method [23] taking into account the measurement period (Fig.2 and Fig5.).
The missing char and the remaining char were measured thrice in different places to get reliable data.
The obtained experimental data were processed using the method of least squares and are given in Table 1.
A specified area of degradation zones is given in Fig.10 and the obtained data are given in Table 2.
