Experimentation programme

The experimental programme was mainly concerned with estimating kinetic parameters from isothermal steady state operation of the reactor. For these runs, the reactor was charged with the reactants, in such proportions that the mixture resulting from their complete conversion approximated the expected steady state, as far as total polymer concentrations was concerned. In order to conserve reactants, the reactor was raised to the operating temperature in batch mode. When this temperature had been attained, continuous flow operation commenced. This was... 

Administration to the airspaces of the IPL can be achieved by instillation, forced sprays and aerosol inhalation. These can achieve regional targeting and should be considered carefully and validated at the beginning of experimental programmes. Drugs can also be administered to the lung via the... 

This project has inspired one of the most ambitious experimental programmes of our day. A major contribution has been made by the CEA (Commissariat d Energie Atomique) in Saclay, France. The neutrino behaves with almost rude indifference towards normal (baryonic) matter. But then we must accept that the matter so familiar to us, making up the stars, the galaxies and our own bodies, is not the dominant form of matter on the scale of the Universe. 

If we have some feel for the reliability of our results and can express this as a standard deviation, we can also express the desired effect in standard deviation units. This is a realistic approach to establishing the size of the experimental programme and should be geared to the effect which we think will be the smallest, provided... 

Prior to the start of a research project, an experimenter wanted to know if three lots of a chemical could be used interchangeably in the experimental programme. The synthesis in question had been carried out using these different lots and yield results were as follows ... 

Known Variables — Controllable In any experimental situation, cettain conditions are held constant during the course of the experiment. A batch of copolymer may be made with a measured quantity of catalyst, at a given reaction temperature, and reacted for a certain definite time. The vessel is free of water, die monomers are charged in a definite proportion, and any other conditions that may affect the result are held fixed. The next portion of the experiment may involve one of these conditions controlled at a new level while the others remain fixed. Proper design of experimental programmes presupposes ability to control the important factors so that the variation due to these factors can be calculated. In Chapter VI, experimental designs for various situations are coveted. 

Known Variables - Uncontrollable or Controllable Within Limits A long series of experiments sometimes involves situations where variation due to changes in one or more factors is known to exist, but where these factors cannot be completely controlled. An example is raw-material quality. Different lots of raw material or catalyst used in an experimental programme may sometimes vary in chemical composition, impurities, activity, etc. Since these items may not be within the control of the user and may not easily be worked into a balanced experimental design, the differences should at least be recorded and their effect taken into consideration during the analysis... 

In looking at the complete experimental programme, it is often useful to think in terms of combinations of experimental designs.

He turned up the music. She didn t know the half of it. Because Rik from Transfix had his brief too, just like they all did. Don t go too weird, we ve got an experimental programme coming on straight after us. Telling him, always, what to play. So he spends half his life working to order in the corporate world then returns to his true self and finds... 

To assess the viability of the copper-chloride cycle, a dedicated experimental programme is proposed the study of the occurrence of possible side reactions. In order not to change the speciation of the vapour phase, the use of optical absorption spectrometry is proposed UV visible spectrometry to detect the possible presence of molecular chlorine, product of side reactions. 

The NO reduction was measured when the platinum/cerium additive was used and it ranged from 15% in the beginning of the experimental programme. After the programme, the engine-out NO, emission was measured. This was approximately 20% below the engine-out emission before the start of the programme. 

The experimental programme was carried out at the Swedish Institute for Metals Research, Stockholm, where initially B. Carlsson and, from 1975, B. Callmer, were responsible for the work, including evaluation of results. Metallography and photomicrography were performed by H. Modin. The companies represented on the Committee supplied samples of steels and made other contributions to the experimental programme. D. Dulieu (BSC, Sheffield Laboratories, England), assisted with the preparation of the English text. The project was partly financed by the Swedish Board for Technical Development. 

When the preclinical testing has been completed to the satisfaction of the developer and of the national or international regulatory agency, it is time to administer the drug to man and so to launch the experimental programme that will decide whether the drug is only a drug or whether it is also a medicine. This is the subject of the next chapter. 

As part of the technical assessment of the biomass hydrogasification concept, an experimental programme was defined in 1999 and performed at Deutsche Montan Technologic (DMT), Germany. 

In suminary, the experimental programme has shown the feasibility of biomass hydrogasification as the most important step within the total process of SNG... 

The experimental programme has shown the feasibility of biomass hydrogasifcation as the most important step of the total process, with respect to the a) production of a methane-rich gas, at the same process conditions (p,T), applied in the modelling work b) conversion of a sufficient amount of biomass to a gaseous product, within a reasonable residence time of biomass feedstock.
