Rough running

The presence of low molecular weight, low flash point compounds in diesel fuel could lead to a shortening of the fuel ignition delay period. In a diesel engine, this could cause rough running due to early combustion of the low flash point compounds. 

Good combustion is characterized by a flame burning uniformly across the piston head. Deposits and poor-quality fuel can interfere with the movement of the flame across the combustion chamber. Rough running can result. 

But isn t this puzzling Consider the following line of thought If reduction is tied to identity so that if a reduces to b, then a = b, then reduction reflexive, transitive and symmetric (see, for example, Trogdon 2013, Section 6). It seems that the best reason for assuming that reduction is symmetric and reflexive roughly runs as follows the fact that (if a reduces to b then a = b) implies that reduction has the structural features of identity. 

In the debate on type-identity theory, the topic of conceptual diversity has been touched on several occasions. Smart (1959) discussed a number of possible objections to type-identity theory, which in fact merely attack a strong version of type-identity theory, rather than the version he, and, according to him. Place tried to defend. These alleged counter-arguments roughly run as follows (Smart 1959, 146 ff.) There is no conceptual route from the mental to the physical, and, therefore, the relevant identity-claims are mistaken. lfa = b, then it is conceptually necessary... 

Sprockets for silent chain wear in a much different way, but noise and rough running still may indicate that the sprockets are worn and need to be replaced. Contact an ACA silent chain manufacturer for more information about silent chain sprocket wear.

This order is quite different from the one found for the corresponding propylene oxide monomer, although the former roughly runs inversely parallel to the latter, as shown in Figure 3. 

For defect sizing by TOED, use of L waves involves a penalty in resolution of almost a factor of two at a given frequency because of difference in velocity as compared to shear waves and use of SV waves runs into difficulties because of the mode conversion problems. Further, problems due to couplant thickness variations, surface roughness affects, beam skewing and distortion problems in anisotropic welds can also be expected. On the contrary, SH waves are not affected... 

Our global subdivision approach is not sensitive to such a situation. Over sufficiently long run times of direct simulation both methods eventually yield roughly the same results, see Fig. 6. 

This will also decrease in the same proportion as the increase in slip. For a rough estimate, we may also ignore the higher slip losses for an equal reduction in the required kW. However, due to the lower voltage the motor current will increase proportionately and will be /,/0.8 or 1.25/,. The motor will thus run overloaded by 25% for 20 minutes which is likely, and not more than once an hour. The frequency of occurrence must be known. A higher derating may be necessary if such a condition is frequent. 

The standard melt flow index machine is often used for characterising the flow properties of polypropylene and to provide a rough measure of molecular weight. Under the conditions normally employed for polyethylene (2.16 kg load at 190°C) the flow rate is too low for accurate measurement and in practice higher loads, e.g. 10 kg, and/or higher temperatures are used. It has been found that a considerable pressure drop exists in the barrel so that the flow towards the end of a test run is higher than at the beginning. 

The use of pilot-plant filter assemblies is both eommon and a elassieal approaeh to design methodology development. These eombine the filter with pumps, reeeivers, mixers, ete., in a single eompaet unit and may be rented at a nominal fee from filter manufaeturers, who supply operating instruetions and sometimes an operator. Preliminary tests are often run at the filter manufacturer s laboratory. Rough tests indicate what filter type to try in the pilot plant. 

Friction factor Describes the relationship between the wall roughness, Reynolds number, and pressure drop per unit length of duct or pipe run. 

Typical runs consist of 100 000 up to 300 000 MC moves per lattice site. Far from the phase transition in the lamellar phase, the typical equilibration run takes 10 000 Monte Carlo steps per site (MCS). In the vicinity of the phase transitions the equilibration takes up to 200 000 MCS. For the rough estimate of the equihbration time one can monitor internal energy as well as the Euler characteristic. The equilibration time for the energy and Euler characteristic are roughly the same. For go = /o = 0 it takes 10 000 MCS to obtain the equilibrium configuration in which one finds the lamellar phase without passages and consequently the Euler characteristic is zero. For go = —3.15 and/o = 0 (close to the phase transition) it takes more than 50 000 MCS for the equihbration and here the Euler characteristic fluctuates around its mean value of —48. 

The table indicates how resource usage varies by problem size. For example, it indicates that for direct MP2 energy calculations, CPU requirements scale roughly as the fourth power of the number of basis functions if the number of electrons stays the same. Using the table with timings from previous jobs (using the same method and executed on the same computer system) should enable you to estimate how long a potential job will run.

The sums in Eqs. (1) and (2) run, respectively, over the reciprocal space lattice vectors, g, and the real space lattice vectors, r and Vc= a is the unit cell volume. The value of the parameter 11 affects the convergence of both the series (1) and (2). Roughly speaking, increasing ii makes slower the convergence of Eq. (1) and faster that of Eq. (2), and vice versa. Our purpose, here, is to find out, for an arbitrary lattice and a given accuracy, the optimal choice, iiopt > tbal minimises the CPU time needed for the evaluation of the KKR structure constants. This choice turns out to depend on the Bravais lattice and the lattice parameters expressed in dimensionless units, on the... 

About 2.5 million tons (2.3 million tonnes) of coal arc burned daily in U.S. power plants. This is equivalent to roughly 21,000 railcars in transit, so it is apparent that coorditiatiiig production and cotistimp-tioii is no easy task. Accidents, rail strikes, natural disasters (e.g., floods that take out bridges and rail lines) and severe weather (e.g., deep river freezes that halt barge traffic) can all severely disrupt deliveries for utility customers dependent on a reliable coal supply for base load plants. Nonetheless, to reduce costs U.S. utilities have significantly reduced typical inventory levels over time. Wliereas a coal inventory of ninety days of supply was once typical, inventories now frequently run in the range of thirty to forty-five days.
