Sensitivity list

Chemical Abstract Service Registry Number for a typical example of the sensitizer listed. See Figure 7 for some stmctural formulas. 

Many analysts are not aware that over one-half of the elements in the periodic table may be determined at levels of one milligram, or less, with commercially available neutron generators. Actual experimental sensitivities are, of course, dependent on levels of interfering activities generated in the activation of complex matrices. The sensitivities listed in... 

Table 1 lists some of the important properties of several commonly observed nuclides in the study of pharmaceuticals. Notice that some elements such as hydrogen, have several magnetically active isotopes with very different properties. Interestingly, has the highest sensitivity to detection of any nucleus, but its use is limited by the added complexity of working with a radioactive isotope. The absolute sensitivity listed in the table takes into account the natural abundance of the isotope. Sensitivity can be improved in some studies by the chemical incorporation of magnetically active isotopes such as and... 

Detection limit in for a 50-Atl. injection. Detection limit taken to be equal to sensitivity listed by Perkin Elmer Corp. 21). 

Notice that WAIT ON (sensitivity lists) are eliminated. Also, WAIT UNTIL with more than a single signal is further restricted this statement must be bracketed by an IF statement with the negated condition. This is caused by the fact that Vhdl (and ProcVhdl) requires a level change to break a WAIT. This is not, in general, compatible with level-sensitive interface protocols.

Despite the large amount of work and despite standardization efforts, the use of HDLs for synthesis is still an unresolved issue. Although VHDL [36] has emerged as a standard for hardware specification, some questions remain as to its applicability as an input language for high-level synthesis. For example, it is unclear what class of applications should be described in a sequential or a functional style, for behavioral specification and synthesis. Furthermore, several language constructs, well suited for simulation, are difficult to synthesize (e.g., dynamic memoiy allocation and sensitivity lists [18]), or are not applicable for synthesis (e.g. assertions). 

The sensitivity list provides die trigger for the execution of the process. Any signal that could be read by the process, and hence affect its behaviour, should be included in the list (Box 5.8). However, when creating a synchronous circuit using a Wait statement (Box 5.6) ti e process is triggered solely by the signal in the VWit expression. A sensitivity list must not be used with a Walt statement. 

The sensitivity list is mandatory. It must contain all signals read by the process. 

In all the above cases, the sensitivity list and the style used to construct the If statements - the templates - enables the synthesizer to determine which sections of the code are synchronous and which are combinational. 

If a Wait statement is used instead of an If, the sensitivity list is not used and the process is fully synchronous. 

A sensitivity list cannot be used. The process is only sensitive to the signal in the clock expression. 

The synthesized circuit consists of three circuits on two levels of the design hierarchy. The architecture itself creates the top level. Inside this there are two concurrent statements - the processes. Each of these creates its own block as Figure 5.29 shows. The inputs to the first block are all the signals read by the COUNTING process whereas the updated signals in this block are output and then read by the second block. This represents the CARRY process. Any signal in this process sensitivity list will be an input to the block (assuming it is read). 

Analytical models using classical reservoir engineering techniques such as material balance, aquifer modelling and displacement calculations can be used in combination with field and laboratory data to estimate recovery factors for specific situations. These methods are most applicable when there is limited data, time and resources, and would be sufficient for most exploration and early appraisal decisions. However, when the development planning stage is reached, it is becoming common practice to build a reservoir simulation model, which allows more sensitivities to be considered in a shorter time frame. The typical sorts of questions addressed by reservoir simulations are listed in Section 8.5. 

The concentration at which micellization commences is called the critical micelle concentration, erne. Any experimental teclmique sensitive to a solution property modified by micellization or sensitive to some probe (molecule or ion) property modified by micellization is generally adequate to quantitatively estimate the onset of micellization. The detennination of erne is usually done by plotting the experimentally measured property or response as a hmction of the logarithm of the surfactant concentration. The intersection of asymptotes fitted to the experimental data or as a breakpoint in the experimental data denotes the erne. A partial listing of experimental... 

The sensitivity of an atomic absorption line is often described by its characteristic concentration, which is the concentration of analyte giving an absorbance of 0.00436 (corresponding to a percent transmittance of 99%). Eor example. Table 10.11 shows a list of wavelengths and characteristic concentrations for copper. 

Aniline prices in the past have been sensitive to the balance between supply and demand in the industry and this trend is likely to continue in the next decade. List prices in the early 1980s began at 0.97/kg, but declined to a low of 0.64/kg as a result of industry overcapacity. By the end of 1987, prices had reached 1.30/kg, and the price has remained firm due to strong demand for aniline. 

List five different structure-sensitive properties. 

There are, of course, many more ceramics available than those listed here alumina is available in many densities, silicon carbide in many qualities. As before, the structure-insensitive properties (density, modulus and melting point) depend little on quality -they do not vary by more than 10%. But the structure-sensitive properties (fracture toughness, modulus of rupture and some thermal properties including expansion) are much more variable. For these, it is essential to consult manufacturers data sheets or conduct your own tests. 

A further detail of this study included sensitivity analysis for the area of heat exchangers, discount rate, and fuel cost. The results are listed in Table 3-8. Option 2, the turboexpander scheme, was selected in terms of energy and maintenance savings, as well as enhanced reliability, availability, and safety. 

Tolerance of animals for fluorides varies, dairy cattle being most sensitive and poultry least (Table 8-3). Fluorosis of animals in contaminated areas can be avoided by keeping the intake levels below those listed by incorporating clean feeds with those high in fluorides. It has also been determined... 

The major effect of such open burning is the nuisance caused by the smoke, but health effects are noticed by sensitive individuals downwind from the bum. Table 30-18 lists the pollutant emissions from grass field burning (15). 

See 2-3.1. Typical laboratory conductivity meters have insufficient sensitivity to measure semiconductive and nonconductive liquids, in Appendix B, some tabulated conductivities appear as < suggesting that the instmment used was inappropriate. Some liquids listed as conductive might fall instead into the semiconductive category (e.g., cymene). Eor conductivities less than 100 pS/m especially, highly sensitive picoammeters are required to measure the small currents involved and great care is needed to avoid contamination of both the sample and the test cell. Several ASTM methods are available according to the conductivity range involved [143-146].
