Both microorganisms showed a high oxidative activity on the ferrous iron initially added to the experiments of chalcopyrite bioleaching, presenting after 12 hours from the beginning, 550 mv for At. ferrooxidans at 300C and over 600 mv for bioleaching with S. acidophilus at 450C (data not shown).
Here, also the results can be explained for the precipitation of jarosite, 600 ppm of total ferrous precipitated (data not shown) on the surface of pyrite in the bioleaching at 45ºC which prevented, on one hand, the active participation of bacteria and, on the other hand, the diffusion of reactive and products on the surface of sulfide.

Applying operations research (OR) [1] in healthcare planning, is a well-known method for the optimal use of resources and reduction in waiting times.
In [5], the authors collected detailed ED arrival data from an urban hospital and used a lag SIPP queueing analysis to gain insights on how to change provider staffing to decrease the proportion of patients who leave without being seen.
Acknowledgements The authors would like to thank the measurement team for their work with the data collection, Dr.

The real-time velocity data was stored in the labtop through a RS232 serial connector and programmed software runs to obtain the real-time CO2 emission by calculating the CO2 concentration coupled with rpm and gas volume.
In order to compare the relationship among gas velocity, rpm, and CO2 emission, time-series data was plotted for 75 minutes shown in the Figure 2.

Mechanical data for Mg single crystal were provided by Kelly and Hosford [2], but even these experiments from 1968 were for the complicated stress state of channel die testing, where non-uniaxiality, friction, and the potential for pre-existing internal twins or small angle boundaries may obviate a reliable analysis of constitutive laws.
A medium level of cleaning (five neighboring points) of zero solution extrapolation has been applied to the data to remove non-indexed points.
Compression tests were conducted up to 50 % reduction at room temperature under the strain rate of 1.0×10-4 s-1 using Instron 8501 universal testing machine.

Generally, photochromic diarylethenes undergo reversible photoinduced cyclization/cycloreversion reactions between two isomers upon irradiation with UV and visible light, and the two isomers of diarylethenes differ from each other not only in their absorption spectra, but in many physical and chemical properties including geometry, refractive index, as well as oxidation/reduction potential, etc [5,6].
As shown in Figure 4, the quality of images recorded in 1c/PMMA film showed a clear contrast and without cross talk, which are important in rewritable data storage.
The optical storage experiment showed that the diarylethene derivative can be use as a data storage medium.

The present existing problems of industrial meters
Arrange available data, extract useful information, define information we need to know.
Because enterprises and institutions increase equipments according to their own conditions step by step, manufactures always allocate meters to meet customers' requirements, and most manufactures deem to keep secret of their technical know-how, finally the following situation of industrial meters comes into being: ①numerous manufactures, numerous meters, large consumption, different standards. ②for the reason that meter operation and maintenance needs a lot of worker personnel, it leads to waste graveness of human resources ③lower equipment compatibility, used inefficiently , overlapping investment, numerous maintenance worker personnel of manufactures, high costs and big energy consumption. ④this situation is not conducive to manufacture health competition , reduction of meters costs and development and renewal of meters. 2.
Draw up detailed communication protocols for accomplishing conversion between control and module, specify Baud rate, format and checking methods of data communication.

Spectral response and electrical characteristics
of the TPV cells fabricated on the base of such double heterostructures are improved due
to reduction of GaInAsSb surface recombination velocity [3] and photon recycling effect.
XRD data showed that FWHM values were lower for the structures grown on GaSb surface treated only in HCL.
The XRD and TEM data on the grown epilayers are indicative of the excellent materials quality and flat interfaces.
