Alkali treatment also helped eliminate the non-cellulosic constituents via reduction in the 1240 and 1750 cm-1 peak.
The FTIR spectrum of the acid-hydrolyzed fibers was similar to those treated with NaOH (data not shown).
The untreated fibers appeared as large clumps without noticeable bundles or fibers (data not shown).
An aqueous dispersion of cellulose was obtained after acid treatment, signifying stabilization due to surface anionic charge [2] and significant size reduction of the alkali-treated fibers.

The control system allows the recording and archiving of process data, which are collected (on-line) by a PLC and transferred to a PC via Ethernet interface.
Registration and archiving of (on-line) process data are provided by an adaptation of PC software, and the process data from a PLC to a PC via the Ethernet interface are delivered.
An adaptation of PC software may concern the creation of a dedicated software application for the execution of the following tasks: a preliminary analysis of measurement data, a full process visualization, and remote monitoring of process data via a web browser.
The idea of the control system provides long-term achievement of process variables, analysis of process data, mathematical modelling of the process and its remote monitoring.
Moreover, the data constitute an important feedback in processes where the high risk of biofilm formation occurs, which is a general problem concerning industry of almost any type.

Hardness measurements Table 2 shows the average hardness data of five samples in each of the three heat treatment conditions (as cast, solubilized and aged).
With the heat treatments, we show a reduction in the niobium concentration in the carbides, which diffuses towards the γ matrix.

Actually, arable land use intensity change is likely Greater threat to regional food security and economic development more than land area reduction [7].
Study Area and Data Sources Study Area.
The town has 13 villages and 3 villages, 109 cooperatives, based on the actual survey data of 2008, the town area of 11592.92hm2.
Data sources.
The original data mainly comes from DaLu town land use change survey data in 2008, DaLu town 2008 Statistical Yearbook, DaLu town comprehensive land consolidation planning (2008-2012), and the author's practical survey, use Bishan County Planning Bureau, trade and Economic Cooperation Bureau, agriculture bureau and other departments data for supplementary.

According to the results of analysis, find out the weak areas in the bed and conduct the weight-lowing optimization on the condition of no reduction of static and dynamic characteristic of the bed.
This paper draws the conclusion of reduction of weight of 143.42kg and materials of 7.73%.
After the extraction of the deformation data of the guide rail displacement, it is seen that the maximum displacement change of the guide rail is the same and the precision meets the requirement.
Finally, the optimization scheme is proposed with the reduction of weight of 143.42kg and materials of 7.73%

Improvement of the functional properties these tools and reduction of the ecological threats may be accomplished by employing the technology of putting down hard coatings on tools in the state-of-the-art PVD processes, mostly by improvement of the tribological contact conditions in the cutting zone and by eliminating the cutting fluids.
In the Fig. 3, there was a gradual reduction in tool life with increasing cutting speed to 200 m min −1 .
Therefore we can view which at increase in cutting speed indicate that the interaction of process energies, including temperature (Fig 4), increases generally and can therefore promote various wear mechanisms, which accelerate tool wear with the consequent reduction in tool life.
However this work the combination these data with that of the tool life, we can conclude that the lubricious/protective TiN film the tool surface during cutting to cutting speed equal to 160 m/min. 0 200 400 600 800 1000 1200 1400 1600 0,0 0,1 0,2 0,3 0,4 0,5 0,6 Flank wear (mm) Cut lenght (m) Vc=200 m/min, ap=0.50 mm, f= 0.20 mm/rev Vc=180 m/min, ap=0.50 mm, f= 0.20 mm/rev Vc=160 m/min, ap=0.50 mm, f= 0.20 mm/rev 0 200 400 600 800 1000 1200 1400 1600 0 100 200 300 400 500 600 700 800 900 Cut lenght Lc (m) Vc=200 m/min, ap=0.50 mm, f= 0.20 mm/rev Vc=180 m/min, ap=0.50 mm, f= 0.20 mm/rev Vc=160 m/min, ap=0.50 mm, f= 0.20 mm/rev Temperature (o C) Fig. 3 Flank wear vs cut length Fig. 4 Temperature vs. cut length.
Agreement Shewmon (1989), we should be concluded that the coating decrease the tool/chip interface temperature by reduction in contact and cutting forces through change in the tribological condition at the tool-chip interface [15].

Third, 4-(5-bromo-4-hydroxyphenyl-3-methoxy)-2-butanone was synthesized by reduction of condensation aldol products with NaBH4 and NiCl2.6H2O in methanol under mild condition.
The structure of compound 1 was confirmed by spectral data (FT-IR, GC-MS, and 1H-NMR).
Nickel boride has been reported as a catalyst for selective reduction of α,β-unsaturated carbonyl compounds like aldehyde, ketone, acid, and ester [15].
FTIR spectra of the product revealed that the reduction has been done successfully; this is shown by the disappearance of C=H trans-bending around 972 cm-1.

-Thermodynamic data The evaluation of the solid fraction can be performed by the use of the phase diagrams, for alloys that liquefy and solidify only under equilibrium conditions.
Based on this data, the modification of A356 chemical composition, by the addition of Cu, from 1 wt% up to 10 wt%, allows to increase the thixoformability of the A356 aluminium alloy.
Additionally, the data obtained using a mathematical model is in good agreement with the data achieved by calorimetric analysis (curve 319s SPSC heating).
Theories and influence of the liquid-solid fraction on the slurry behaviour have been discussed based on data available in the recent and past literature.
The SSM processing model and its use has been introduced some years ago, but still now, there is a serious need for additional and more detailed rheological data.
