Not prohibited

The time for a measurement is determined mainly by the movement of the samples, because they are turned continuously during the data acquisition. If not prohibited by the geometry of the sample, a fast scan with 128 x 128 pixels is done in less than one minute. Scans of higher... 

Under the New Approach Member States shall not prohibit, restrict or impede the placing on the market or putting into service of products which comply with the directives and bear the CE-marking. Member States have also the obligation to take all appropriate measures to ensure that the products placed on the market do not endanger the health and safety of persons. 

The sustained world popularity of NSP results from simplicity of production and high agronomic quaHty as a carrier of available P2O5, calcium, sulfur, and usually some incidental micronutrients. In terms of agronomic value for large numbers of crops, no phosphate fertilizer has been shown to be superior to NSP. It is likely to remain in strong demand in parts of the world where simplicity of production or sulfur fertilization has high priority and where transportation costs are not prohibitive. 

The measured pressure drops were slightly greater than literature data would indicate for packed carbon beds. However, they are certainly not prohibitive and a successful outcome of the Westinghouse trial of the SOFC guard bed is anticipated. 

The standard does not require that you purchase only from approved subcontractors . It does require that you maintain records of acceptable subcontractors but does not prohibit you from selecting subcontractors that do not fully meet your purchasing requirements. There will be some subcontractors that fully meet your requirements and... 

Orbital Bomb. A satellite contg a nuclear warhead which circles the earth in a low orbit and which can be commanded to descend on a particular target. No such weapons are now known to be operational, and their deployment would be prohibited under the terms of the Outer Space Treaty of 1966. However, this treaty does not prohibit anything making less than a full circle around the earth, hence the FOBS... 

Spills of endosulfan, according to FAOAVHO (1975a), should be cleaned up by first washing with 5% sodium hydroxide solution and then rinsing with large quantities of water. In addition, empty containers that held endosulfan residues should be rinsed two or three times with water while the sides are scrubbed, and once with 5% sodium hydroxide solution. Thus decontaminated, the empty containers can be recycled and used by pesticide manufacturers to package a chemical similar to endosulfan if the containers remain in good condition and if such reuse is not prohibited by federal, state, or local laws. 

Aluminum metal is produced from aluminum oxide by electrolysis using the Hall-Heroult process, whose story is detailed in our Chemical Milestones Box. The melting point of AI2 O3 is too high (2015 °C) and its electrical conductivity too low to make direct electrolysis commercially viable. Instead, AI2 O3 is mixed with cryolite (Na3 AlFfi) containing about 10% CaF2. This mixture has a melting point of 1000 °C, still a high temperature but not prohibitively so. Aluminum forms several complex ions with fluoride and oxide, so the molten mixture... 

In screening electrolyte redox systems for use in PEC the primary factor is redox kinetics, provided the thermodynamics is not prohibitive, while consideration of properties such as toxicity and optical transparency is important. Facile redox kinetics provided by fast one-electron outer-sphere redox systems might be well suited to regenerative applications and this is indeed the case for well-behaved couples that have yielded satisfactory results for a variety of semiconductors, especially with organic solvents (e.g., [21]). On the other hand, many efficient systems reported in the literature entail a more complicated behaviour, e.g., the above-mentioned polychalcogenide and polyiodide redox couples actually represent sluggish redox systems involving specific interactions with the semiconductor... 

GL 1[ [R 1[ [R 3] [P la-d] When the fluorine-to-toluene ratio is increased, conversion increases in a linear fashion [38]. This basically means that transport resistance would most likely not prohibit using still higher fluorine contents, thereby further possibly increasing the productivity (space-time yield) of the reactor (Figure 5.19). 

The FDA does not prohibit the use of other techniques that could provide unambiguous structural information such as Fourier transform infrared (FUR) spectrometry. However, the requirement for relatively large amounts of sample for an analysis has limited the use of such techniques. 

Customer preference is also an increasingly important consideration when selecting biocides for use in products. Large manufacturers such as Ford, Volvo, BMW and SKF, to name but a few, are producing lists of materials they do not want to see in their factories. Many biocides are on these lists. Currently, they are not prohibited, but this may only be a matter of time. 

In order to understand the thermodynamic issues associated with the nanocomposite formation, Vaia et al. have applied the mean-field statistical lattice model and found that conclusions based on the mean field theory agreed nicely with the experimental results [12,13]. The entropy loss associated with confinement of a polymer melt is not prohibited to nanocomposite formation because an entropy gain associated with the layer separation balances the entropy loss of polymer intercalation, resulting in a net entropy change near to zero. Thus, from the theoretical model, the outcome of nanocomposite formation via polymer melt intercalation depends on energetic factors, which may be determined from the surface energies of the polymer and OMLF. 

Where installation costs are not prohibitive, the ideal remedy would be a suspended concrete floor above a well ventilated space, with the ground below the ventilated space sealed by concrete incorporating a polymeric radon barrier. This would effect a passive remedy requiring little maintenance and no running costs. 

For some gassy systems (Ap/At driven), viscosity considerations become important which make testing difficult if not prohibitive. 

The minimal basis calculation on the hydrogen molecule is a well-worn but eminently suitable example for our purposes. It has a convenient symmetry element and orbital basis calculations can be carried through which are quantitatively acceptable and yet not prohibitively unwiedly to report. We give below variational calculations on the H2 molecule using the familiar simplest AO basis in the one-electron-group (MO) model and the electron-pair (VB) model. These calculations have been performed explicitly to investigate the effect of symmetry constraints . 

Very often the carbon framework of the future allene is already present in the substrate and often it is propargylic in nature. For example, base-catalyzed isomeriza-tions of acetylenic hydrocarbons - with the triple bond in a non-terminal (40) or terminal position - were often used to prepare allenic hydrocarbons in the early days of allene chemistry [8]. The disadvantage of this approach consists in the thermodynamic instability of the allenes produced if not prohibited for structural reasons, the isomerizations do not stop at the allene but proceed to the more stable conjugated diene stage. In practice, complex mixtures are often formed [9] (see also Chapter 1).

Dr. Flinn However, it is not prohibitively troublesome if one obtains a single-line source, which is possible. There are various possible cubic environments for antimony, and you don t encounter the problem with magnetic eflFects that you do with the rare earths. It is a little more trouble, but it is quite manageable, and it doesn t interfere seriously with the experiments. 

Scheme 4 Steric factors do not prohibit electroreductive cyclization.

Also, in the case of DMC, reaction conditions apparently are not green the methylating ability of DMC can be exploited at a temperature >160°C (above the boiling point of DMC itself 90°C), which implies an autogenic pressure (> 3 bar) for batchwise processes. Such conditions are not prohibitive, however, especially according to the industrial practice, where pressures up to 20-30 bar and temperatures up to 250°C are not a concern. 

Availability" of an alternative in this context implies the existence of an alternative - capable of providing an acceptable level of performance - acceptable to the regulator, user, (and consumer if relevant) at a cost that is not prohibitive and whose supply is adequately assured. 

However, if the test samples are sufficiently balanced to cover the sample states used to build the model without extending beyond those states, and the cost of obtaining and analyzing these test samples is not prohibitive, then the test set validation method can be very effective. In fact, in some high-stakes applications where model evaluation is the main objective, such validation is required, often with the stipulation that the known reference values of the test samples are withheld from the method developers by the testing authority - a procedure also known as blind validation.
