Internationalised Normal Ratio(INR) elevations and/or bleeding events have been reported in some patients taking warfarin(see Pharmacokinetic Properties' section). patients taking warfarin should be monitored regularly for changes in prothrombin time or INR. patients shouldbe advised to seek medical advice promptly in the event of developing any eye symptoms or severe or persistent diarrhoea , nausea vomiting or anorexia(see Pharmacokinetic Properties' section). These symptoms should be managed as clinically indicated. Randomised controlled trials have demonstrated that Iressa combined with doublet , platinum-based cytotoxic chemotherapy in advanced NSCLC provides no added benefit over ther cytototxic in patientswho have previously received treatment with cytotoxic chemotherapy. In a phase I/II trial of IRESSA and radiation in paediatric patients, newly diagnosed with brain stem glioma or incompletely resected supratentorialmalignant glioma, 4 cases(1fatal) of CNS haemorrhages have been reported from trialwith IRESSA alone. There is no evidence to suggest any increased risk of cerebral haemorrhage in adult patients with NSCLC receiving IRESSA. Phase IIclinical trial data, where IRESSA and vinorelbine have been used concomitantly, indicate that Iressa may exacebate the neutropenic effctof vinorbine. Interaction with other medicinal products and other forms of interaction In vitro studies with human hepatic microsomes have shown that the metabolism of gefitinib is predomiantly via the CYP3A4 isoform of the hepatic cytochromeP-450 system. Gefitinib may be sxpected to interact with otehr drgs that induce, inhibit or are metabolised by this system. Gefitinib showed littl enzyme induction effect in animal studies and in vitro sutdies have shown that gefitinib has limited potentialto inhibit CYP2D6. The clinically or potentially significantclinical drug interactions between gefitinib and the following drugs/ durg classes are described below. Other Drugs that effect gefitinib Demonstrated interactions Drugs that inhaibit CYP3A4 co-administraion with itraconazole(a CYP3A4)resuulted in an 80% increase in the mean AUC of gefitinibin healthy volunteers. This increase may bbe clinically relevant since adverse experiences are related to dose and exposure. Although interaction studies with other CYP3A4 inhibitors have not been performed it is expected that drugs such as ketoconaxole, clotrimazole, ritonovir would also inhibit gefitinib metabolism. Drugs that Increase gastric pH In a trial in healthy volunteers co-adminstrationof drugs that cause significant sustined elevations in gastric pH>=5, resulted in a reduced mean gefitinib AUC by 47%. This may reduce efficacy Rifampicin Co-administration with rifa mpicin(a known potent CYP3A4 inducer) in healthy volunteers reduced meangefitinib AUC by 83% of that without rifampicin.

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. 展开

LabVIEWisapowerfulandcomplexprogrammingenvironment.LabVIEWisshortforLaboratoryVirtualInstrumentEngineeringWorkbench.Itisapowerfulandflexibleinstrumentationandanalysissoft... LabVIEW is a powerful and complex programming environment. LabVIEW is short for Laboratory Virtual Instrument Engineering Workbench. It is a powerful and flexible instrumentation and analysis software development application created by the folks at National Instruments—a company that creates hardware and software products that leverage computer technology to help engineers and scientists take measurements, control processes, and analyze and storem data. National Instruments was founded over twenty-five years ago in Austin, Texas by James Truchard (known as Dr. T), Jeffrey Kodosky, and William Nowlin. At the time, all three men were working on sonar applications for the U.S. Navy at the Applied Research Laboratories at The University of Texas at Austin. Searching for a way to connect test equipment to DEC PDP-11 computers, Dr. T decided to develop an interface bus. He recruited Jeff and Bill to join him in his endeavor, and together they successfully developed LabVIEW and the notion of a “virtual instrument.” In the process they managed to infuse their new company—National Instruments—with an entrepreneurial spirit that still pervades the company today. Engineers and scientists in research, development, production, test, and service industries as diverse as automotive, semiconductor, aerospace, electronics, chemical, telecommunications, and pharmaceutical have used and continue touse LabVIEW to support their work. LabVIEW is a major player in the area of testing and measurements, industrial automation, and data analysis. For example, scientists at NASA’s Jet Propulsion Laboratory used LabVIEW to analyze and display Mars Pathfinder Sojourner rover engineering data, including the position and temperature of the rover, how much power remained in the rover’s battery, and generally to monitor Sojourner’s overall health. LabVIEW provides an extensive library of virtual instruments and functions to help you in your programming. It includes conventional program debugging tools with which you can set breakpoints, single-step through the program, and animate the execution so you can observe the flow of data. 毕业设计急用,望高手帮忙翻译一下 展开

These detectors may alter the view of a signals appearance, depending on which is selected. Each detector can show a different picture on the same signal because of the way the detector functions. An important selection to our spectrum analyzer is the amount of digital snap shots to be taken. This will be the amount of digital snapshots that is taken in the allocated bandwidth before showing a picture. With this said, the more sampling that is put into the spectrum analyzer the slower it will seem to update, but more opportunity to capture ingress and other interference that can happen inside a cable plant. Dwell Wide- Dwell Wide takes the largest snapshot out of the amount taken, then the 7.5 MHz spectrum is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. Example: In Dwell Wide, with a 32 sampling rate set, this in turn means the 860 will dwell or sit on a portion of the spectrum defined above, take 32 snap shots, and then display the picture with the max amplitude before moving on to the next portion of bandwidth. Dwell Narrow- Dwell Narrow takes the largest snapshot out of the amount taken, then a 250 kHz spectrum slice is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. The difference between Dwell Narrow and Dwell Wide is that Dwell Narrow only peak holds across a 250 kHz slice, where as Dwell wide peak holds the entire 7.5 MHz. Example: In Dwell Narrow, with a 32 sampling rate set, this in turn means the 860 will go to the first 7.5 MHz of the spectrum it will look at a 250 kHz slice of the 7.5 MHz and take its 32 samples. These 32 samples will be done in a peak hold fashion, then display the sample that contains the largest signal. Averaging: This detector when selected looks at a 7.5 MHz portion of the spectrum. When it tunes to the first 7.5 MHz portion of the spectrum, it takes into account how much sampling is selected, then takes it’s digital snapshots on the entire 7.5 MHz, averages those pictures together, then shows the final averaged picture. This detector is used for looking at large amounts of bandwidth. Example: In Averaging, with a 32 sampling rate set, this in turn means the 860 will go to the first 7.5 MHz of the spectrum, take it’s 32 digital snap shots, average those together, and show the average of the 32 snapshots. 展开

A new kind of TiO2 nanotube array/Ni(OH)2 (TiO2/Ni(OH)2) composite electrode with the storage ability of light energy was prepared by the deposition of Ni(OH)2 on the TiO2 nanotube array, which was synthesized by anodizing Ti foils in an HF aqueous solution. SEM and XRD results showed that Ni(OH)2 particles were well distributed on high density, well-ordered and uniform TiO2 nanotube arrays. The photoelectrochemical properties of the TiO2/Ni(OH)2 electrode were investigated in NaHCO3/NaOH buffer solution (pH 10) by means of UV–vis absorption spectra, cyclic voltammogram (CV) and photocurrent measurements. It was found that the TiO2/Ni(OH)2 electrode was highly sensitive to light and exhibited excellent photoelectrochromic properties. Upon UV irradiation, the photogenerated holes by TiO2 nanotube arrays can oxidize Ni(OH)2 to NiOOH, and thus the TiO2/Ni(OH)2 electrode can be photo-charged by light。1. Introduction Among many visible light photocatalysts, TiO2nanostructures have attracted much attention due to high photocatalytic activ-ity, nontoxicity, chemical stability and huge potential applications [1–6]. The TiO2 nanotube array is one of most attention-getting TiO2nanostructures because of large surface area and outstanding charge transport properties. TiO2nanotube arrays can be utilized in dye-sensitized solar cells[7–9], photocatalysis and hydrogen gas sensing [10]. So far, a variety of methods have been attempted to prepare TiO2 nanotube arrays, such as hydrothermal synthe-sis[11], Langmuir–Blodgett technique [12], solution casting [13] and anodization technique[10,14], etc. Among these methods, the anodization technique has many advantages of low cost, low tem-perature and easy to be scaled up to large-area preparation. Recently, anewkindof photo-functional systemwith theenergy storage ability has been developed by coupling TiO2 photosen-sitive electrode with energy storage materials. In Takahashi and Tatsuma’swork[15],aTiO2/Ni(OH)2bilayer thinfilmwas suggested for the oxidative energy storage. In this case, a redox-activep-type semiconductor Ni(OH)2is coupled withn-type TiO2photocatalyst to formap–njunction,WhenTiO2is illuminatedby light, holesgen-erated at the junction are separated from excited electrons, trans-ported into the bulk of Ni(OH)2and oxidized Ni(OH)2to NiOOH. Therefore, the oxidative energy storage system was constructed 展开

Physical and physicochemical characterization The particle size distribution of the Ch-zeolite was determined using a laser diffraction equipment (CILASk 1064) and standard wet sieving (Mesh Tylerk series). Scanning electron microscopy (SEM-PHILIPSk XL20) was used for photomicrographs as well as to analyse the Ch-zeolite composition (Energy Dispersion X-ray, EDX). The sample was initially placed in a vacuum chamber for coating with a thin layer (few nanometers) of gold (Au). The specific surface area of the material was measured by the methylene blue technique and by nitrogen gas adsorption methods, with the latter also providing information about particle porosity. In the methylene blue adsorption method, aqueous solutions (50 ml) of methylene blue (100 mg l 1) were agitated using an orbital shaker (Marconik) for an hour at room temperature in the presence of different quantities of the Ch-zeolite (0.05–0.3 g). The suspensions were then allowed to settle for 23 h and the resulting supernatants were centrifuged at 5000 rpm before the analysis of the residual methylene blue concentration. Results obtained correspond to averaged values of three different experiments. The specific surface area was evaluated by the Langmuir model, assuming the formation, at high concentrations, of a dye monolayer and 1.08 nm2 molecule 1, for the cross-sectional area (Van den Hul and Lyklema, 1968). The Ch-zeolite specific surface area was evaluated by the nitrogen gas adsorption method, using automated equipment (Autosorb 1-Quantachrome Instrumentsk), employing multipoint BET isotherm adsorption data fitting. Also from these data, the porosity of the material was evaluated through parameters such as volume of total pores (d < 206 nm), surface area and volume of micropores (d < 2 nm; Micropore Analysis Method). Zeta potential measurements for the natural and ammonia loaded zeolite, as a function of medium pH, were determined using a Zeta Plusk equipment (Brookhaven Instruments). Suspensions (0.01% v/v) of the Ch-zeolite, previously sieved below 37 Am (400 Mesh Tylerk), in a 10 3 mol l 1 solution of KNO3 were used and the medium pH was controlled with the addition of HNO3 (pH< 7) and KOH (pH>7), separately. For the Ch-zeolite saturated with ammonia, suspensions of the material were prepared by the same procedure, except that the sample was loaded with 100 mg NH3–N l 1 of ammonia. 展开
