Real controllability

Manganese(III)-promoted radical cyclization of arylthioformanilides and a-benzoylthio-formanilides is a recently described microwave-assisted example for the synthesis of 2-arylbenzothiazoles and 2-benzoylbenzothiazoles. In this study, manganese triacetate is introduced as a new reagent to replace potassium ferricyanide or bromide. The 2-substituted benzothiazoles are generated in 6 min at 110°C imder microwave irradiation (300 W) in a domestic oven with no real control of the temperature (reflux of acetic acid) (Scheme 15). Conventional heating (oil bath) of the reaction at 110 °C for 6 h gave similar yields [16]. [Pg.69]

ASCII text is the traditional SAS output found in the SAS LST file, which is the ODS FISTING destination. With ASCII text output you are working with a nonproportional monospace font, and the only real control you have over your output presentation is in using the SAS PAGESIZE and LINESIZE options. However, traditional ASCII text with a monospace font is not a bad option. By using ASCII text with a monospace font you get these benefits ... [Pg.191]

The actual scope and limitations of chemical analysis of odour show that all problems can be tackled as far as emission is concerned. For immission measurements some progress is necessary, but there is no essential reason why chemical analysis would be unable to attain the desired sensitivity for all types of odorants. There is no doubt that in a few years the last difficulties will be solved. In order to achieve real control of odour nuisance, automatic measurement is necessary on a long time basis. There again some technical development is to be expected. [Pg.169]

The first attempts at ROP have been mainly based on anionic and cationic processes [4,5]. In most cases, polyesters of low molecular weight were recovered and no control on the polymerization course was reported due to the occurrence of side intra- and intermolecular transesterification reactions responsible for a mixture of linear and cyclic molecules. In addition, aliphatic polyesters have been prepared by free radical, active hydrogen, zwitterionic, and coordination polymerization as summarized in Table 2. The mechanistic considerations of the above-mentioned processes are outside the scope of this work and have been extensively discussed in a recent review by some of us [2 ]. In addition, the enzyme-catalyzed ROP of (di)lactones in organic media has recently been reported however, even though this new polymerization procedure appears very promising, no real control of the polyesters chains, or rather oligomers, has been observed so far [6]. [Pg.5]

Its employees are essentially free agents with tenure over which the university corporation has no real control. I am not suggesting that somehow there is something wrong with the faculty. I am simply saying there is something wrong with the structure. [Pg.105]

Nuremberg statutes for crimes against humanity — for deploying drug-runners and convicted Nazis for assassinations of worldshaking importance. Before the Zionist Lobby shouts "anti-Semitism," it must explain the composition and directorate of Permindex, which exposes once and for all the real controllers of the Nazi "Black" International. [Pg.320]

Of the characterized higher boranes larger than B10Hu, all except BnH15 are of the conjuncto class, consisting of two or more cluster units joined in some manner (for two examples see Fig. 5-3). A variety of synthetic approaches has been employed to prepare these hydrides, in most cases generating products serendipitously with no real control over the product compositions or structures. Typical examples are as follows ... [Pg.141]

In a dynamic simulation, controllers are used to model the real control valves of the process. When converting a steady-state simulation to a dynamic simulation, some care is needed to ensure that the controller functions correspond to physically achievable control structures. [Pg.221]

Based on the polarity difference between CO2 and the interior of the micelles, w/c microemulsions have found many applications as extraction media. Furthermore, by modifying pressure and temperature, solvent quality may be changed and it becomes, therefore, possible to exert a real control over the extraction process uptake of solutes inside micelles may be varied. This may be of use for separations/extractions involving bio-chemicals and proteins. In conventional solvents their separation from the reaction medium can be quite complicated, involving tedious processes such as fluid-fluid extraction, decantation, chromatography column, filtration, precipitation. Use of supercritical fluid technology with extraction in reverse micelles seems advantageous for proteins (e.g. 19, 76). This process was also used for the extraction of metals (77-79) and more recently of copper from a filter paper surface (1). [Pg.291]

Safety committees can be toothless advisory bodies, or they can have a measure of real control over the conditions of work. In most European countries they have significant power, although in the peripheral regions where social policy is less developed (Ireland, England, Italy, and Greece) they are primarily consultative. On the other hand, even without statutory reinforcement these bodies can influence conditions in... [Pg.203]

Humans need to feel in control of their responses and, if possible, of the environmental conditions causing those responses. The feeling of control, however, does not always mean that real control is being exercised. There is evidence that unconscious preparation for physical movement actually precedes the conscious decision to make that movement (Obhi and Haggard, 2004). Thus, it appears as if the movement is somehow preplanned in the brain before the person decides that the action is to happen. Conscious control of the movement then appears to determine not what movement is to take place, but only whether or not the preplanned event will actually happen. Free will, it seems, is actually free won t. [Pg.467]

The authors hope that these ideas will help managers and operators understand the real control problem after delays and figure out how it can be corrected to reduce fuel rates, reduce rejects, and improve product quality. [Pg.253]

Communications can be connected in parallel to the real station systems, allowing the simulator to be used in place of the real control room during emergency exercises. [Pg.135]

Using nonapproved components makes the pmduct manufacturer responsible. This includes responsibility for the component s design, construction, documentation, and ongoing compliance, areas where the end-product or machine manufacturer have no real control. [Pg.91]

DMSR design). The basic design goal has been to limit the fraction volume of salt out of core to be one-third to one-half of fhe fofal volume. In the MSRE however, it operated with nearly two-thirds of salf ouf of core wifh no real control concerns (ORNL TM 0730,1964). [Pg.273]

This system of work leads to a major disjunction between safety and compensation. At law, employers are responsible for compensation and must carry workers compensation insurance. Thus the subcontracting firms carry the main costs of workers compensation. However, the principal contractor exercises close control over the subcontractors and even over their employees. In these circumstances the law imposes the primary responsibility for the safety of these workers on the principal contractor. (Subcontractors are responsible at law only to the extent that they exercise real control over the work process.) The result of these arrangements is that compensation costs cannot provide safety incentives so far as project management is concerned. Insofar as the principal contractor is safety conscious this must be for reasons other than the costs of compensation. By way of qualification, it should be noted that some industry leaders are now employing a greater proportion of the workers on site directly. Where this happens the disjunction will be correspondingly blurred. [Pg.130]

In summary, the valve position shown in the control room may or may not correspond to the real control valve position. [Pg.512]
