Sensitiveness test results

There seems to be a noticeable difference in the Ball Drop Impact results and this could be attributed to the inherent error associated with this relatively crude test for instance, the manner and precise location, at which the steel ball impacts the explosive particles can vary and lead to inconsistent results. Friction and electrostatic sensitivity was consistent across all of our batches of DBX-1 as well as PSEMC DBX-1 (Table 3) In terms of determining the effectiveness of a primary explosive, sensitivity tests results are generally only predictive in how to safely handle the material in order to determine if the explosive is practical or not, performance tests need to be done to see how well the material behaves in actual items, such as detonators. 

It was determined that complete coverage was not achieved until approximately 10% wax was present. Sensitivity tests results indicated that neither the wax nor the coating method used had a significant effect, provided the coating method leads to good dispersion of the wax thruout the high expl... 

The characteristic points on the friction sensitivity curve Fo, F50, and Fioo, are reported as the friction sensitivity test results. Alternatively, the smallest loading of the pistil at w4iich initiation is observed at least once in six trials may be reported as the test result. 

Once cultures and sensitivity testing results become available, the antibiotic regimen is then modified to improve cost-benefits, enhance outcome, reduce toxicity from unnecessary drug exposure, and discourage the emergence of multidrug-resistant bacteria within a hospital environment. 

This paper describes the result obtained in a study of AFCEN (French Society for Design and Construction Rules for Nuclear Island Components) in order to characterize dye penetrant product family, based on experimental test methods of french standards NFA 09.520 and NFA 09.521. In particular, sensitivity tests have been carried out on artificial defects, and correlated with tests on real defects. Some tests on penetrant washability have also been performed. The results obtained with these three series of tests show that the choiee of a dye penetrant product family is not without influency on results obtained, and that is not so simple to make the good choice which could, in certain cases, be the less bad compromise. 

The tables 5 and 6 give the results of sensitivity tests obtained on the nickel-chromium specimens of 20 and 10 pm for the fluorescent range products, and of 50 and 30 pm for the colored range of products. 

The sensitivity test on nickel-chromium test blocks show that products which give bad results to over washing tests generally do not give good results to sensitivity tests. 

In co-operation with LM Glasfiber, a complete section of a rotor blade was produced with a number of well defined defects in order to perform an initial sensitivity test by means of ultrasound, vibrations techniques and real-time radiography. Based on the results of this initial test it was found that automated ultrasonic inspection was the best suited teclmique. In co-... 

The molecular uniformity of constituting components of a nb/lcb glucan fraction of potato starch was investigated with Sepharose CL 2B (Fig. 16.16) as well as with Sephacryl S-1000 (Fig. 16.17). Therefore, each of the subsequently eluted 3-ml fractions was analyzed on their potential to form inclusion complexes with iodine, a sensitive test for the presence of nb/lcb glucans. Results are shown in Fig. 16.17 in terms of branching index, the ratio of extinction of pure iodine solution and of nb/lcb glucan/iodine complex the higher the index, the more pronounced the nb/lcb characteristics. 

This test has possible advantages over the notched Izod test. The notch sensitivity factor is eliminated, and energy is not used in pushing aside the broken portion of the specimen. The test results are recorded in ft-lb/in.2 (kJ/m2). This allows for minor variations in dimensions of the minimum in cross-section area. 

There have been few discussions of the specific problems inherent in the application of methods of curve matching to solid state reactions. It is probable that a degree of subjectivity frequently enters many decisions concerning identification of a best fit . It is not known, for example, (i) the accuracy with which data must be measured to enable a clear distinction to be made between obedience to alternative rate equations, (ii) the range of a within which results provide the most sensitive tests of possible equations, (iii) the form of test, i.e. f(a)—time, reduced time, etc. plots, which is most appropriate for confirmation of probable kinetic obediences and (iv) the minimum time intervals at which measurements must be made for use in kinetic analyses, the number of (a, t) values required. It is also important to know the influence of experimental errors in oto, t0, particle size distributions, temperature variations, etc., on kinetic analyses and distinguishability. A critical survey of quantitative aspects of curve fitting, concerned particularly with the reactions of solids, has not yet been provided [490]. 

The nurse should take and record vital signs. When appropriate, it is important to obtain a description of the signs and symptoms of the infection from the patient or family. The nurse assesses the infected area (when possible) and records finding on the patient s chart. It is important to describe accurately any signs and symptoms related to the patient s infection, such as color and lype of drainage from a wound, pain, redness and inflammation, color of sputum, or presence of an odor. In addition, the nurse should note the patient s general appearance. A culture and sensitivity test is almost always ordered, and the nurse must obtain the results before giving the first dose of penicillin. 

Promoting Optimal Response to Therapy The results of a culture and sensitivity test take several days because time must be allowed for the bacteria to grow on the culture media However, infections are treated as soon as possible In a few instances, the primary health care provider may determine that a penicillin is the treatment of choice until the results of the culture and sensitivity tests are known. In many instances, the primary health care provider selects a broad-spectrum antibiotic (ie, an antibiotic that is effective against many types or strains of bacteria) for initial treatment because of the many penicillin-resistant strains of microorganisms. 

Because of the risks of adverse reaction to the vaccine by persons who had already been exposed to the disease a sensitivity test must be carried out prior to immunization with BCG. A Mantoux skin test assesses an individual s sensitivity to a purified protein derivative (PPD) prepared fi om heat-treated antigens (tuberculin) extracted fiom M tuberculosis. A positive test imphes past infection or past, successful immunization Those with strongly positive tests may have active disease and should be referred to a chest clinic. Many people with active TB, especially disseminated TB, however, sero-convert fiom skin test positive to skin test negative. Results of the skin test must therefore be interpreted with care. 

Quality of analytical equipment specificity, accuracy, precision, and sensitivity of measuring and analyzing equipment determine the reliability of test results. 

Table 1 provides the urinalysis test results for the 4,847 arrestees, While PCP was tested for by an EMIT test only, cocaine, opiates and methadone were tested for by both EMIT and thin layer chromatography (TLC). (The EMIT test for opiates is not specific to morphine, the metabolite of heroin, and can detect the recent use of a variety of opiates. A specimen positive for opiates is most likely to indicate the use of heroin in this population, however.) Our analyses will use only the results from the EMIT tests, because we have learned that the TLC general drug screen is less sensitive for detecting recent use of these illicit street drugs (Wish et al. 1983 Wish et al. 1984).

In analytical chemistry, the term error (used in the sense of deviation) is defined by the difference between the test result (xtest) and the true value (x, i.e., the accepted reference value, see ISO 3534-1 [1993] Fleming et al. [1997]). The term may be related both to measured value y and analytical value x which correspond to each other according to the sensitivity factor b of an analytical procedure. 

Results of sensitiveness tests on typical explosives are given in Table 6.1, for steel to steel surfaces, in the absence of grit. 

This is the basis for our new test of linearity. It has all the advantages we described it gives an unambiguous determination of whether any nonlinearity is affecting the relationship between the test results and the analyte concentration. It provides a means of distinguishing between different types of nonlinearity, if they are present, since only those that have statistically significant coefficients are active. It also is more sensitive than any other statistical linearity test including the Durbin-Watson statistic. The tables...
