True method

Nowell, Edward. Certain chemical works with the true practice gathered into a true method by Edward Nowell. B. M. Sloane 2567. R.A.M.S., 1982. 40p. [Pg.77]

Chemistry is a French science. It was founded by Lavoisier, of immortal memory . .. he was at once the author of a new theory and the creator of the true method in chemistry and the superiority of the method gave wings to the theory.39... [Pg.41]

True method development calls upon the technical expertise of the analytical department and more specifically the project analytical chemist to assess the nature of the chemical entity under investigation and the matrix in which it is present. Success or failure in method development is directly attributable to the analyst s overall technical competence and breadth of knowledge in various analytical techniques. Technically challenging analysis problems are usually handled by more senior members of the laboratory staff or those possessing advanced education and training. [Pg.148]

Something akin to this MAY actually happen in the Regeneration, but not by any such process, which is cited in the philosophical books merely to awaken a perception of the true method of confection. This philosophical confection of the Stone is a work of the laboratory, in a sense purely manual and mechanical, so far as the part which man plays in the work. With all that, it is something vastly above making brass tacks or compounding medicines. It demands a pure heart and a keen intellect, with unfolded reason and unbounded faith and reliance on spiritual guidance. [Pg.15]

Any suspicious lesion that appears to alter the surroimding skin, causing loss of eyelashes or irregular lid margins, which cannot be determined as benign, must be referred for biopsy this is the only true method to diagnosis a malignancy. It is not uncommon to confuse a BCC... [Pg.403]

ISO 5725 [7] relies on a statistical analysis of variance model with two variance components "laboratory" and "repetition". Hence, a homogeneous material is assumed. Only under this homogeneity condition the calculated precision values are true method characteristics. For a heterogeneous material, like the tested cementitious mortar, the precision values are contaminated by the variance component of the material. Therefore, the precision values represent both material and method characteristics. [Pg.461]

Most severely ill patients in the late nineteenth and early twentieth centuries continued to be housed in overcrowded state mental hospitals and were "treated" using tried and true methods of the day seclusion, restraint, and wet sheet packs. Although seemingly inhumane procedures were employed, it may be important to consider that the psychiatrists of that era were relatively helpless in the face of very severe mental illnesses and that these approaches (although certainly misused at times) reflected their attempt to reduce the horrendous human suffering seen in thousands of severely ill people. [Pg.6]

The attempts that have been made to utilize true chemometric optimization of operating conditions in CEC are unclear in most of the studies done utilizing CEC. This has been done for many years in GC and HPLC, as well as in CE, but there are no obvious articles that have appeared which have utilized true chemometric software approaches to optimization in CEC [57-59]. It is not clear that any true method optimization has been performed or what analytical figures of merit were used to define an optimized set of conditions for biopolymer analysis by CEC. It is also unclear as to why a specific stationary phase (packing) was finally selected as the optimal support in these particular CEC applications for biopolymers. In the future, it is hoped that more sophisticated optimization routines, especially computerized chemometrics (expert systems, theoretical software, or simplex/optiplex routines) will be employed from start to finish. [Pg.177]

The last major strategy is the old tried and true method of pitting one place against another. There is just no better way to rile the competitive, capitalistic being inherent in a customer service/sales rep and get them to... [Pg.96]

The indicator card would be a true method of measuring the volumetric efficiency if the temperature of the air after being drawn into the cylinder were the same as that of the atmosphere, and if the pressure at the end of the suc-tion stroke were the same as that of the atmosphere. This is never the case. [Pg.170]

Pham Phlash is a tried and true method of pharmacology instruction. Students learn to take clues from both the generic and trade names. When I ask students What kind of drug ends with olol, ilol, or alol, they can tell me quickly that these are beta-adrenergic blockers. As a pharmacology instructor, this is music to my ears. I hope you will experience the same results. [Pg.16]

Bubble tube or differential pressure is an old, but tried and true, method of bed level detection. There may be some plugging or fouling of the tube over time. [Pg.2016]

All available sources were used to obtain the data in this reference making it the definitive resource on PZC/IEP. Destined to become a classic. Surface Charging and Points of Zero Charge points the way for further research with tried and true methods that help researchers avoid the doubt that can lead to countless hours of unnecessary research. [Pg.1065]

A true method without precision (whatever this could really mean ) does not tell us anything. Before verifying trueness, the analyst must assess the level of precision he has achieved. The study of the reproducibility R and repeatability r of the method is the preliminary task of the validation procedure and can be largely done with own laboratory RMs. However, in order to know if the achieved performance of R and r are comparable to the actual state of the art of the method or of the market, the analyst can use a CRM. When later on he tries to assess the trueness of his method he must also achieve a precision performance which allows the CRM to tell him about his trueness performance. ISO Guide 33 [2] helps to evaluate simply the precision performance criteria. The use of BCR-CRMs, which are certified by interlaboratory studies where several independent and different methods are used, can help a bit further. [Pg.79]

A Double Block and Bleed means two block valves with a bleed valve located between them. Bleed-off valving for pressure instrumentation on hot lines is provided with a double block and bleed valve. These valves and the bleed piping for hot services should not be less than 1/2 in. or 3/4 in. in size. They are arranged so that a rod may be driven up the valve and fitting. Many refiners still believe in the tried-and-true method of using double block and bleed valves for bubble-tight service. [Pg.321]

The model should be (1) descriptive, (2) predictive, and (3) prescriptive, leading to actions. Francis Bacon in Novum Organum wrote, Nature to be commanded must be obeyed. .. The true method of experience first lights the candle (i.e., generates an hypothesis), and then, by means of the candle, shows the way, and then experiment itself shall judge. ... [Pg.55]

Safety and loss prevention professionals, as is human nature, often rely on the tried-and-true solutions to problems, which have worked in the past. In the safety and loss prevention area, this often means relying on the Occupational Safety and Health Administration (OSH A) standards or other base-level requirements to resolve the problem. If OSHA requires that a particular problem be addressed in a specific manner, then this is the method that must be used. This tried-and-true method does work however, what does a safety and loss prevention professional do when the answer to a problem is not in the OSHA standards Are there alternative resources Are there other strategies that can be used to obtain a solution to the problem ... [Pg.1]

With the remaining, true methods there are numerous overlaps. Top-down approaches, for example, will often be based on algorithmic models. An expert, when asked to produce an estimate of effort, might in fact use any method, including asking another expert. However, there is some evidence that experts tend to adopt an analogy approach. If a previous application that is a reasonable match... [Pg.255]

The use of any analytical method implies that the method, if employed properly, will yield an acceptable result. However, a client of an analytical service is entitled to have some documentary evidence that this assertion is true. Method validation (q.v.) is a lengthy process that is applied to a new method after development to provide evidence that the method will indeed produce results to satisfy the client s requirements. Figure 2 is a schematic of the different aspects of a method that may be considered during method validation. [Pg.3981]

That you would have abolished all committees and have conveyed all business into the true method of the usual trials of the commonwealth. [Pg.138]
