Live testing

Laboratory methods - looking at scientific and molecular areas with testing in vitro (lab methods like cell cultures) and in vivo (on live test animals). 

The bottom up fire is started by igniting the kindling. The test fuel Is added, when the fire bums lively. Test file) shall be added not more than twice during the same bum cycle. 

For APIs with short shelf lives, testing should be done more frequently. For example, for those biotechnological/biologic and other APIs with shelf lives of one year or less, stability samples should be obtained and should be tested monthly for the first three months, and at three-month intervals later. When data exist that confirm that the stability of the API is not compromised, elimination of specific test intervals (e.g., nine-month testing) can be considered. Where appropriate, the stability storage conditions should be consistent with the ICH guidances on stability. 

Discrepancies between the observed B WTs recorded during the collection of the mostly live benthic foraminiferal specimens and predicted BWTs (calculated using equations 6 and 7) point to the possibility that a seasonal isotope effect influences the S Oforam values of benthic foraminifera in Loch Sunart (Fig. 7). In particular, the similarity of the predicted BWT for samples collected in April to the observed BWT of samples collected in June/July suggests that live tests collected in the cool BWTs of April actually calcified during the warmer BWTs of the previous summer (Fig. 7). For example, the measured 8 Oforam of C. lobatulus collected from a BWT of 7.88 °C in April, 2001, 3delds a predicted BWT of 13.45 °C and is similar to the... 

The hunt for early records of life hinges critically, of course, on understanding what constitutes firm evidence, criteria for which have matured as studies of Precambrian paleobiology have come of age (Schopf and Walter, 1983 Schopf, 1992a, 1993). Namely, to be acceptable, evidence of past life must meet the following live tests ... 

While live testing may be required by workers in the electrical industries in order to find the fault, live repair work must not be carried out. The individual circuit or piece of equipment must first be isolated before work commences in order to comply with the Electricity at Work Regulations 1989. 

Some live testing Is allowed by competent persons ... 

When the person carrying out the inspection is satisfied with the results, the tests listed in BS 7671, section 713, should be carried out, following the recommended sequence to ensure that it is safe to energise the circuits for the final three live tests. The main tests are described in the following sections. 

Live testing of equipment, apparatus and installations is a eommon eause of electrical injury and frequently requires eareful consideration and planning of the precautions needed to reduee the risks to an acceptable level. In all cases it is essential that the person earrying out the test is competent, having received adequate training and instruction on the risks and the technique to be used to avoid injury. There should always be a sufficiently comprehensive risk assessment carried out, with a clear and unambiguous explanation of the safety precautions. The main techniques that can be employed, most often in combinations, are ... 

Techniques developed by Advanced Tissue Sciences, La Jolla, CA [21], have allowed accurate assessment of skin and eye irritation potential of nominally irritating substances such as surfactants by studying their effects on the viability of live cultured human tissue. The methods are rapid and sensitive, and greatly reduce the need to use live test animals.
