The performances of NaLS and NaHLS as drilling fluid additive were tested according to API Procedure No.13B Scheme 1 The hydroxymethylation of lignosulfonate and formaldehyde Results and Discussion Evaluation of NaHLS as drilling fluid additive Data for the NaHLS samples, as well as LS, prepared for drilling fluid tests were given in Table 1, which include: plastic viscosity(PV), yield point(YP), apparent viscosity(AV), gel strength(G10s), filter loss(FL), density(ρ), pH value, specific conductance(S) and thickness of mud cake(H).
NaLS and NaHLS can reduce the FL under room temperature and 120℃ with 0.9-3.5 ml reduction compared with the FL of base mud.
These data imply that NaHLS functions are better than NaLS under any conditions, particularly under higher temperatures (180 ℃) and that further work on this new class of additives is warranted.

It followed the evolution of the temperature on a period of 20 minute of phone conversation; it made data acquisition at every 5 minute.
During the tests it takes into account the reduction of the measurement and analysis errors to obtain the accurate and fair measurements.
Fig. 1 Initial thermal map Fig. 2 Thermal map after 20 minutes of phone conversation From the analysis obtained by the data acquisition in the two areas (Figure 3 and Figure 4) it observes the trend of temperature increasing related to the exposure time at the electromagnetic radiation of the cell phone during the conversations.

The key idea is an automated, quick, precise and robust method capable of estimating a set of geometric transformations that resample all images with respect to a reference one, so that the new data will be consistent among themselves.
The central image i of the sequence is assumed as reference and, assuming a relationship xk=Hk,k-1xk-1 between consecutive images, any other is processed using the following criteria: (4) Fig. 1 shows an example of data processing, where a set of 9 bracketed photos was geometrically aligned to generate a final HDR mosaic.
The use of a cascaded matching, where one uses only consecutive image pairs, allows a reduction of CPU time.

The data reveal that the adsorption energy of H2O on the molybdenite surface (100) is the largest, -14.14 kJ/mol; then molybdenite surface (010), -12.13 kJ/mol; molybdenite surface (001), -10.59 kJ/mol; talc surface (100), -3.46 kJ/mol; talc surface (010), -1.48 kJ/mol; talc surface (001), -0.20 kJ/mol (negative sign represents exothermic reaction).
The data show that the adsorption energies of H2O molecules on molybdenite and talc surfaces are little than binding energy between H2O molecules (∆E=EH2O-mineral-EH2O-H2O >0).
Chander and Fuerstenau [9] postulated that the reduction in floatability is due to the presence of electrical charges on the edges of the molybdenite that originate from the oxidation and hydrolysis of MoO3 to HMoO and MoO[10].

The bacterial induction including heterotrophic bacteria (bacilli) and lactic acid bacteria but insignificant acetic acid bacteria, together with a reduction of reducing sugar contents (data not shown) were observed during the first stage of fermentation (days 1-8) (shown in Fig. 2 and Fig. 3).
At the end of wine process, both samples had final alcohol contents at 12-13% (v/v) (data not shown).

Given the collected data, the revised nearest neighbor imputation method is summarized as follows: 1) Determine the number of oscillations in the collected data, and choose the number of nearest surrounding vectors equal to the number of oscillations; initiate the iteration indices k and d with and d=0, respectively. 2) Locate the m nearest neighbors of , denoted as …,.The distance between any element of {…} and u[k] is measured by the squared error between the two values. 3) Based on the locations ,,…, we find the counterparts of {…} in y, namely, ,….

The maximum blank sheet thickness reduction of the simulated parts with both materials is less than 30%.
The required data for these contact definitions can be captured by using an optical measuring system and the new developed load device.
The data for the contact modeling of sub-assemblies will be captured by using the new developed load device and the optical measuring system Pontos HS (Fig. 7).

Introduction RFID (Radio Frequency Identification) is an automatic identification technology which identifies object via non-touching dual-directional data communication by using radio frequency technique.
UHF RFID system working in 915 MHz has received widely attention and research because of the advantages of its small size and high data transfer rates.
With transformation of the folded shape and reduction of the size, the tag antenna becomes difficult to conjugate match with the chip.
