Residues of malachite green (MG) were extracted from homogenized animal tissues with a mixture of McIlvaine buffer (pH 3.0)–acetonitrile， and purified over an aromatic sulfonic acid solid-phase extraction column followed by HPLC or LC–ESI-MS–MS analysis. Ascorbic acid and N，N，N9，N9-tetramethyl-1，4-phenylenediamine dihydrochloride were added to reduce de-methylation of the dye. Responses were recorded at 620 nm (HPLC) or by multiple-reaction-monitoring (LC–MS–MS) after post-column oxidation using PbO2 . MG and its primary metabolite leuco-malachite green (LMG) were successfully determined at 2.5–2000 mg / kg in catfish， eel， rainbow trout， salmon， tropical prawns and turbot， with a limit of detection at 1 mg / kg (HPLC) and 0.2 mg / kg (LC–MS–MS) for both MG and LMG. Recoveries for LMG were between 86±15% (prawn) and 105±14% (eel). Freeze–thawing cycles， and storage at 4°C and -20°C affected the recovery of both MG and LMG. Analyses of eel， trout and (processed) salmon field samples collected at local retailers， fish-market and -shops demonstrated trace levels of MG-residues. A McIlvaine solution at pH 3.0 was prepared by mixing 18.9 ml 0.2 M sodium hydrogen phosphate and 81.1 ml 0.1 M citric acid， whereas these volumes were 62.5 and 37.5 ml， respectively， to obtain a McIlvaine solution at pH 6.0. The SPE-eluent was prepared just before use and consisted of a mixture of 2.5 ml 25% (m/v) ammonium hydroxide， 2.5 ml 1.0 mg/ml methanolic ascorbic acid and 45 ml methanol. The sample-solvent was composed， just before use， from 2.5 ml 1.0 mg/ml methanolic ascorbic acid， 20 ml 50 mM sodium perchlorate containing 25 mM sodium acetate and 25 mM 1-pentanesulfonic acid adjusted to pH 4.0 with acetic acid， and 27.5 ml acetonitrile. Chemicals and solutions containing the dyes were protected from light. Fish were bought at the fish market and local stores. Blank trout were collected from aquaria at Utrecht University (The Netherlands). Tropical prawns were collected by the Dutch Inspectorate for Health Protection and Veterinary Public Health. 展開

In this paper， the degradation of an azo dye Orange G (OG) on nitrogen-doped TiO2 photocatalysts has been investigated under visible light and sunlight irradiation. Under visible light irradiation， the doped TiO2 nanocatalysts demonstrated higher activity than the commercial Dugussa P25 TiO2， allowing more ef?cient utilization of solar light， while under sunlight， P25 showed higher photocatalytic activity. According to the X-ray diffraction (XRD)， X-ray photoelectron spectroscopy (XPS) and UV–vis spectra analyses， it was found that both the nanosized anatase structure and the appearance of new absorption band in the visible region caused by nitrogen doping were responsible for the signi?cant enhancement of OG degradation under visible light. In addition， the photosensitized oxidation mechanism originated from OG itself was also considered contributing to the higher visible-light-induced degradation ef?ciency. The effect of the initial pH of the solution and the dosage of hydrogen peroxide under different light sources was also investigated. Under visible light and sunlight， the optimal solution pH was both 2.0， while the optimal dosage of H2O2 was 5.0 and 15.0 mmol/l， respectively. Azodyes， which are characterized by the presence of one or more azo bonds ( N N )， are among the most notorious widespread environmental pollutants associated with textile，cosmetic， food colorants， printing， and pharmaceutical indus-tries. Because of their non-degradability， toxicity， potential mutagenicity and carcinogenicity， wastewaters originating from these dyes production or application industries pose a major threat to the surrounding ecosystems and human beings’ health.[1–3].Environmental concerns and the need of meeting the strin-gent international standards for rejecting wastewaters has made the development of novel and cost-effective processes for the puri?cation of azo dyes ef?uents an issue of major technological importance. 展開

Caution:Do not place your finger over the vent(it pressurizes the sensor) to test the flow indicator when gas is flowing to the sensor.removing your finger (the restriction) generates a vacuum on the sensor and maydamage the sensor(voiding the sensor warraty). Positive pressure applications: If the sample pressure is greater than 30 psign an external pressure regulator(optional) is required upsteram of the analyzer to control of sample flow.a pressure regulator with a metallic diaphragm is recommended to prevent high oxygen reading that cuold result from the use of diaphragms constructed of more gas permeable materisls. If other optionoal sample system components such as coiled metal tubing(samples must be colled to at least 35-40℃ for continuous use)，coalescing filters ，scrubbers，etc.are required install the pressure rugulator after the coiled tubing and bofore the other components and the analyzer.a scrubber requires a flow valve upstream for optimum efficiency and response time and that the analyzer flow valve is opened completely. Atmospheric or slightly negative pressure applications: For accurate high ppb and/or low ppm range measurements，an optional simple pump is required downstream of the analyzer to draw the sample through the analyzer.The cacuum drawn on the analyzer and sensor should not exceed 4”of water. Caution:Use ofpump downstream of the sensor requires the floe control valve upstream of the sensor be completely opened to avoid drawing ercessive vacuum in the sensor，which can damage the sensor. If pump over-loading(due to the limitation of low flow rate of the sample gas)is a comsideration，a second throttle valve on the pump’s inlet side may be necessary to provide a bypass path，as illustrated below，to prevent the pump from over-loading and over-heating while miantaining the required sample flow rate within the above-mentioned parameters 展開

After concentration in a rotary evaporator， the obtained material was dried in air at 383 K overnight and subjected to preliminary reduction with a 1N2/3H2 stream at 698 K， and then cooled in 1N2/3H2 atmosphere. The potassium promoter was introduced by incipient wet impregnation with KNO3 solution at room temperature with molar ratio of K+ /Ru = 5/1. After stirring for 6 h and infusing for 24 h， the samples were dried in a rotary evaporator at 343K and then dried in the air at 383K for 12 h. The ammonia synthesis activities of the catalysts with about 35-60 meshes were evaluated by 1N2/3H2 flow of 2100 mL/h at 0.2 MPa from 623 K to 773 K. The amount of effluent ammonia was determined by titration method. As we can see from the Table 1， under the same reaction conditions， the catalyst K-Ru/Mg(Al)O exhibited the highest activity， 38.42 mL NH3?h-1?g-1 at 673K， 3 times more active than K-Ru/MgO， 12.88 mL NH3?h-1?g-1 at 748K. This means that selection of supports takes great effects on the activity of catalysts. The ammonia synthesis activity of different supports are K-Ru/Mg(Al)O > K-Ru/Mg-Al-Ca(1) > K-Ru/Mg-Al-Ca(2) > K-Ru/Al2O3 > K-Ru/CaO > K-Ru/MgO. The combinatorial supports showed higher activity than single supports. However， the sequence of temperature corresponding to the highest activity is just opposite to that of the activity. The optimal temperature for K-Ru/Mg(Al)O， 673K， is the lowest of all， on the contrary， that of K-Ru/MgO is the highest， 748K. The Mg(Al)O has a larger surface area of 140.95 m2?g-1 ， similar to γ-Al2O3， 110-180 m2?g-1 . The other two combinational supports have little surface areas but higher activities than Al2O3. It suggested that the activity of the catalyst is influenced not only by the dispersion of Ru crystals but also by the crystal structure of the supports.

Plant material and culture conditions have been described (7). Briefly， a diploid tissue culture line， WOO1C， of wild carrot， Daucus carota L.， was maintained in Murashige and Skoog medium supplemented with 0.1 mg of 2，4-dichlorophenoxyacetic acid (2，4-D). To regenerate plants from the culture， callus tissue was transferred to the same medium devoid of 2，4-D (embryogenic medium). All experiments were performed with cultures grown in liquid medium. For convenience， cultures grown in 2，4-D-containing medium are referred to as "callus cultures"， and those grown in medium without 2，4-D as "embryo cultures." The growth of callus cultures was measured by the sidearmturbidity method (7). The number of cells at any time point of growth was estimated from turbidity in a Klett-Summerson calorimeter and was expressed in arbitrary units. For example， Klett 100 corresponds to ="2 X 106 cells per ml. The relationship is linear up to Klett 150 in our Klett-Summerson colorimeter. Suspension cultures ofWOOLC cell line are normally maintained at cell densities between 106 and 107 cells per ml in 0.1 mg of 2，4-D per liter (high-density culture) in shake flasks. During a quantitative study on embryogenesis， we found that maximal embryo production can be achieved by first incubating the culture at high density in medium without 2，4-D for one generation time and then diluting it to 2-3 x 104 cells per ml (low-density culture). To compare cultures of comparable density， callus cultures and embryo cultures were subjected to the same procedure. To initiate low-density embryo or callus cultures， an 8-day-old high-density culture grown at the logarithmic phase was washed three times with fresh callus or embryogenic medium and resuspended at 8 x 105 cells per ml for one generation (3 days) in its corresponding medium. It was then diluted to 2 x 104 cells per ml; 20 ml of the culture was incubated in a plastic Petri dish (9 cm in diameter) at 240C. The morphogenetic events of the cultures were examined and photographed under a dissecting microscope. 請不要用google的那個，我看不懂~~ 展開

Nano-sized Beta zeolites， with a crystal size of 80–100 nm， were synthesized via surface wet method. The nano-sized Hbeta zeolites exhibit much higher activity and stability in the Friedel–Crafts acylation of anisole and toluene with acetic anhydride than theconventional zeolites of largeparticle size.The smallcrystalsize of nano-sized zeolitesmay bringon more accessible activesites and then enhance the catalytic activity. The exposed pore openings in nano-sized zeolites allow a fast desorption of heavy products from the catalyst and can then reduce the occupancy of active sites by the adsorption of products ，this can then alleviate the catalyst deactivation and improve the catalyst stability deactivation and improve the catalyst stability. 急用 在線等 拒絕用自動翻譯 因為這個誰都會 如果有超級好用的自動在線翻譯或軟件也可以推薦 展開

- Theelementalcontentofrawmaterials，phosphogypsum，substrate(potassiumsalt)，products(superphosphateand“Amofoska”)，soil，andgrasswasdeterminedusingconventionalandepithermaln... The elemental content of raw materials， phosphogypsum， substrate (potassium salt)， products (superphosphate and “Amofoska”)， soil， and grass was determined using conventional and epithermal neutron activation analysis using the IBR-2 pulsed fast reactor at Frank Laboratory of Neutron Physics (FLNP)， Joint Institute for Nuclear Research (JINR)， Dubna， Russia. The analytical procedure was described elsewhere by Frontasyeva and Pavlov [15]. Quality control was based on the application of certified reference materials (CRMs): IAEA-336 (lichens)， IAEA-SDM (lake sediment) and IAEA-SL1 (soil). The certified values and the results obtained by NAA were compared (Table 2). Concentrations of most elements were in good agreement with the CRMs except for Ti， Ni， Ce， Eu， Dy and Rb， which differed from the certified value as follows: Ti - 41.7 %， Ni - 26.5 %， Ce - 24.3 %， Eu - 32.9 % and Dy - 33.3 % in IAEA-SL1 (soil) and Rb - 20.6 % in IAEA-336 (lichens). For the 21 elements in agreement with the certified values the bias observed was below 20 %. For 11 elements (Al， V， Mn， As， Br， Sc， Cr， Sm， Na， Co and Sb)， the bias ranged from 0.03 % to 5 %， for 5 elements (Fe， Zn， Ba， Th and Cs) the bias was greater than 5 % but lower than 10 %， and for 5 elements (La， Tb， Hf， Ta and U) the bias was determined to be between 10 % and 20 %. Samples of raw materials， phosphogypsum， substrate， products， soil (of about 0.1 g)， and grass (0.3 g) were irradiated in cadmium-screened channels 1 and 2 of the pneumatic “Regata” system described elsewhere by Frontasyeva and Pavlov [15]. In order to determine elements associated with long-lived radionuclides， samples were irradiated for 100 hours. Spectra of induced gamma activity were recorded after 4 and 20-24 days of cooling. Short irradiations， 5 minutes for grass samples and 60 seconds for the remaining samples， allowed determination of Al， Ca， Cl， I， K， Na， Mg， Mn， Ti and V. Gamma-ray spectra were recorded after 5 and 12 minutes after irradiation. Data processing was performed using software developed at FLNP JINR [16， 17]. All gamma-spectrometers and counting electronics were made at JINR [16]. The software developed at FLNP JINR for peak searching， peak fitting， and nuclide identification routines were used for processing the amplitude spectra [16]. In the case of the lack of analytical data， there was a half of the detection limit inserted for each analyte [18]. Principal component analysis (classical PCA and fuzzy PCA) was performed as a tool for searching the possible correlations between environmental and industrial samples that could implicate the impact of phosphatic fertilizer production on the environment adjacent to the plant. 請給一個比較能看懂的翻譯，謝謝. 展開

A reversed-phase ion-pairing high-performance liquid chromatography (RP-HPIPC) method for the separation of a complex mixture of heparin-derived oligosacchrides has been developed by a stepwise optimization of the mobile phase， in which the concentration of ion-pairing reagent， mobile phase pH， and acetonitrile concentration were varied. The resolution of more than 30 oligosaccharide components was obtained， under optimized conditions， in an analysis time of less than 30 min. This represents the first RP-HPLC method that can separate a complex mixture of both small and large sulfated oligosaccharides in a single chromatographic step. The heparin-derived oligosaccharides， in this mixture， can also be separated under a second set of RP-HPIPC conditions using a volatile ion-pairing reagent， tributylammonium acetate， to aid in the recovery of individual sulfated oligosaccharides. Moreover， it was possible to replace sodium chloride gradient， required for eluting highly sulfated oligosaccharides， with a fixed， low concentration of a volatile salt， ammonium acetate， by utilizing an acetonitrile gradient. This solvent system might make it possible to directly interface this RP-HPIPC separation with mass spectral analysis. ??2003 Elsevier B.V. All rights reserved.

What's therole of the Supercapacitor? The supercapacitor resembles a regular capacitorwith the exception that it offers very high capacitance in a small package.Energy storage is by means of static charge rather than of an electro-chemicalprocess that is inherent to the battery. Applying a voltage differential on thepositive and negative plates charges the supercapacitor. This concept issimilar to an electrical charge that builds up when walking on a carpet. Thesupercapacitor concept has been around for a number of years. Newer designsallow higher capacities in a smaller size. Whereas a regular capacitor consists ofconductive foils and a dry separator， the supercapacitor crosses into batterytechnology by using special electrodes and some electrolyte. There are threetypes of electrode materials suitable for the supercapacitor. They are: highsurface area activated carbons， metal oxide and conducting polymers. The highsurface electrode material， also called Double Layer Capacitor (DLC)， is leastcostly to manufacture and is the most common. It stores the energy in thedouble layer formed near the carbon electrode surface. 展開

The Raman spectra were excited from the samples held at room temperature，at an excitation wavelength of 517．4 nm and with a Nd—YAG laser operated at 1064 cm 1and 10 mW ． The spectra were recorded on a Renishaw Raman spectrometer with the sample mounted in a backscattering(180°) geometry and at a resolution of 4 cm -1． Results and Discussion Although all the diffraction lines can be fitted with a spinel structure very well，we cannot unambiguously distinguish the layered α一NaFeO2 structure(space group R3m )from the spinel structure(space group Fd3m ) only based on those X—ray diffraction data． Raman spectroscopy must be employed to identify the real structure of the materials． Ammundsen et al. have calculated the Raman—active modes for spinel structure based on factor group analysis，showing that there should be five bands for the spinel structure． Fig.2 shows the Raman spectra of LiMn204 sintered at 500 and 600 ℃． There is a significant difference between the spectra from the samples sintered at these two temperatures，i.e.，there are five Raman peaks for the sample sintered at 500 ℃ and only two peaks for the sample sintered at 600 ℃ ．Five calculationpredicted Raman—active modes for LiMn204 are one mode of Alg symmetry，one mode of Eg symmetry，and three modes of T2g symmetry .Accordingly， LiMn204 sample sintered at 600 ℃ seem s not to be crystallized in the spinel structure，while LiMn204 sample sintered below 500 ℃ is crystallized in the spinel structure．Usually，the low—temperature(LT) phase of LiCoO2 exhibits the spinel stucture，while the high—temperature(HT ) phase of it exhibits the α一NaFeO2 structure． According to our Raman data，the LT phase of the LiMn204 powder exhibits the spinel structure， which displays the same tendency as LiCo02 materia1． 展開

IFRS 13 will help increase transparency when entities use models to measure fair value， particularly when users need more information about measurement uncertainty， such as when the market for an asset or a liability has become less active. IFRS 13 requires entities to disclose information about the valuation techniques and inputs used to measure fair value， as well as information about the uncertainty inherent in fair value measurements (which was of particular concern during the global fi nancial crisis). Some of those disclosures， including the fair value hierarchy， were already introduced in March 2009 through an amendment to IFRS 7 Financial Instruments: Disclosures. Those disclosures have been relocated to IFRS 13. The requirements in IFRS 13 also incorporate the guidance in a FASB Staff Position (FSP) issued in April 2009. 展開

Wells-Brookfield Cone/Plate Rapid Determination Of Absolute Viscosity Introduction The Wells-Brookfield Cone/Plate Viscometer gives researchers a sophisticated instrument for routinely determining absolute viscosity of fluids in small sample volumes. Its cone and plate geometry provides the precision necessary for development of complete rheological data. Principle of Operation The Wells-Brookfield Cone/Plate Viscometer is a precise torque meter which is driven at discrete rotational speeds. The torque measuring system， which consists of a calibrated beryllium-copper spring connecting the drive mechanism to a rotating cone， senses the resistance to rotation caused by the presence of sample fluid between the cone and a stationary flat plate. The resistance to the rotation of the cone produces a torque that is proportional to the shear stress in the fluid. The amount of torque is indicated either on a dial or digital display， depending on model. This reading is easily converted to absolute centipoise units (mPa.s) from pre-calculated range charts. Alternatively， viscosity can be calculated from the known geometric constants of the cone， the rate of rotation， and the stress related torque. See Range Tables The correct relative position of cone and plate is obtained by following a simple mechanical procedure without the need for external gauges or supplementary instrumentation. The stationary plate forms the bottom of a sample cup which can be removed， filled with .5 ml to 2.0 ml of sample fluid (depending on cone in use)， and remounted without disturbing the calibration. The sample cup is jacketed and has tube fittings for connection to a constant temperature circulating bath. The system is accurate to within ?.0% of the working range. Reproducibility is to within ?.2%. Working temperature range is from 0oC to 100oC. 展開
