Positive recall meaning

In continuous production, product is inspected by taking samples from the line which are then examined while the line continues producing product. In such cases you will need a means of holding product produced between sampling points until the results of the tests and inspections are available. You will also need a means of releasing product when the results indicate that the product is acceptable. So a Product Release Procedure or Held Product Procedure may be necessary. The standard implies, however, that if you have released product under positive recall procedures you do not need to hold product while in-process inspection and tests are performed. The reference to clause 4.10.3(a) is also ambiguous because the inspections and tests carried out in accordance with the quality plan or documented procedures may not cover those necessary to verify product on receipt into the plant. It would be wise to hold any product until you have... 

We recall that at closed discharge conditions fluid particles stay at a fixed axial position. This means that the fluid in the crosshatched incremental volume Ay = nNDHAl does not leave it. Some fluid is dragged over the flight and recycled to the bulk, and since within the volume element the fluid circulates due to the drag of the barrel surface, we can model the system as a well-stirred tank with recycle, as shown in Fig. 9.17. 

FVom the results of Anosov, Klingenberg, and Takens, it follows that in the set of all geodesic flows on smooth Riemannian manifolds there exists an open everywhere dense subset of flows without closed stable integral trajectories [170], 17l. This means that the property of a geodesic flow to have no stable trajectories is the property of general position. Recall once again that we mean strong stability (see Definition 2.1.2). 

This process is a hydroboration-oxidation, which will add water across the double bond. The first step is to determine the regiochemical outcome. That is, we must determine where the OH is positioned. Recall that hydroboration-oxidation produces an anti-Markovnikov addition, which means that the OH is positioned at the less substituted carbon ... 

It would be considered prudent to prohibit the premature release of product if you did not have an adequate traceability system in place. If in fact any nonconformities in a component will be detected by the end product tests, it may be worth allowing production to commence without the receipt tests being available, in which case the tests will only be confidence checks and not verification checks. If only one product is received and released prior to verification one would think that, as the requirement applies prior to verification, there is no need to positively identify the product to permit recall because you would know where it was if you found it to be nonconforming. However, the nonconformity may have been reported to you by the supplier after delivery. The standard does not stipulate when and by whom the nonconformity may have been detected. If you lose the means of determining conformity by premature release, don t release the product until you have verified it is acceptable. 

The derivation of the equations of the Debye-Huckel theory did not require differentiation between a solution of a single electrolyte and an electrolyte mixture provided that the limiting law approximation Eq. (1.3.24), was used, which does not contain any specific ionic parameter. If, however, approximation (1.3.29) is to be used, containing the effective ionic diameter ay it must be recalled that this quantity was introduced as the minimal mean distance of approach of both positive and negative ions to the central ion. Thus, this quantity a is in a certain sense an average of effects of all the ions but, at the same time, a characteristic value for the given central... 

We recall from Chapter 1 how the symbol A means final state minus initial state , so a positive value of AVm during melting (which is Vm (iiqUid) — Vm (SOiid)) tells us that the liquid has a slightly larger volume than the solid from which it came. AVm (meit) is positive in the overwhelming majority of cases, but for water AVm (melt) = —1.6 x 10-6 m3 mol-1. This minus sign is extremely unusual it means that ice is less dense than water. This explains why an iceberg floats in water, yet most solids sink when immersed in their respective liquid phases. 

Another way of stating the exclusion principle is that no two electrons in an atom have the same four quantum numbers. This important idea means that each electron in an atom has its own unique set of four quantum numbers. For example, compare the quantum numbers that distinguish a ground state hydrogen atom from a helium atom. (Recall that a helium atom has two electrons. Note also that mg quantum number is given as +. It could just as easily have a value of —By convention, chemists usually use the positive value first.)... 

We will now adjust our position to within a few microns of the interface and examine the flux. Flux is molecular at the interface between two phases, as illustrated in Figure 8.3. This means that is zero and the only active process is diffusion. Note the difference in the order of magnitudes of D and s given in Figure 8.3, and recall the resistance concepts that we discussed in Chapter 2. The resistance to mass transfer is much larger near the interface than away from the interface, so the controlling process would tend to be transfer in the diffusive sublayer. 

Hence, ArG° is a measure of the free energy of the reaction when all species are present in their standard state (where concentrations are assumed to be 1 M, and activity coefficients are set to 1). We should recall that a negative ArG0 would mean that, under standard conditions, the reaction Eq. 12-1 would proceed spontaneously from left to right if ArG0 is positive, the reaction would proceed spontaneously in the opposite direction. 

Recall from Section 2.10 that the characteristic feature of extensive properties XL is their uniform scaling with respect to the size of the system, expressible in terms of a multiplicative positive scale factor A. Re-sizing the macroscopic system merely means that all extensive properties are multiplied by the common scale factor A,... 

Unit-cell symmetry can also simplify the search for peaks in a three-dimensional Patterson map. For instance, in a unit cell with a 2X axis (twofold screw) on edge c, recall (equivalent positions, Chapter 4, Section II.H) that each atom at (x,y,z) has an identical counterpart atom at (-x,-y,V2 + z). The vectors connecting such symmetry-related atoms will all lie at (u,v,w) = (2x,2y,V2) in the Patterson map (just subtract one set of coordinates from the other), which means they all lie in the plane that cuts the Patterson unit cell at w = l/2. Such planes, which contain the Patterson vectors for symmetry-related atoms, are called Harker sections or Harker planes. If heavy atoms bind to the protein at... 

Recall that integration undoes differentiation, in the sense described in Chapter 1. This means in turn that we integrate the force to get the difference in potential energy between two positions, say r and r2 ...
