External contraction

Toller An outsourced manufacturing company contracted to process materials to another company s specifications. Sometimes called third party service provider, toll processor, supplier of outside services, external contract manufacturer, contract processor, contract manufacturer, custom chemical manufacturer.

In the past, accessing these data has usually involved the creation of complex, specialised computer programs, either in-house or via external contracts. Both... 

The MP2-R12 method can be regarded as an externally contracted MP2 method with (contracted) double excitations into a complete spin orbital basis. To illustrate this, we shall in the following discuss an externally contracted MP2 method that comprises contracted double excitations into a subspace (Pp-, which has been orthogonalized against the orbital basis (pp, ... 

The orthogonal subspace used in Table I is spanned by the large basis 0=19sl4p8d6f4g3h2i, H=9s6p4d3f2g. The number of basis functions of the large basis that are (nearly) linearly dependent on the cc-pVnZ basis is drastically increased with the cc-pVnZ basis sets. We observe that the externally contracted MP2 calculations converge faster to the MP2 limit. As expected, the energies from the externally contracted MP2 method lie between the standard... 

MP2 values and the energy obtained in the (uncontracted) large basis. As the size of the orthogonal subspace increases the computational effort of the MP2 calculation, the externally contracted MP2 methods does not appear to be a practicable method. It merely illustrates the explicitly correlated MP2-R12 theory. 

Validation requires money, time, planning, and documentation. It also, however, requires human resources to push the buttons, collect the data, submit the samples, analyze the collected samples, summarize the reports, and gather the required signatures. Most validations are very resource-intensive undertakings. Somehow companies must assure that the requisite resources are available. Although not recommended, these resources may be external (contracted laboratory, consultants, etc.). With the exception of a qualified contract laboratory, the... 

Subcontracting for compound procurement (purchasing and/ or synthesis) and compound profiling assays (by networked researchers or external contract research organizations). 

Finally, Siegbahn has suggested two procedures for reducing the number of variational parameters in a MR-CISD wavefunction. The first method, externally contracted MR-CISD,88 expresses eq. (37) as... 

Finally, the results obtained above on the CASSCF level of approximation were checked by a set of multireference Cl calculations using the externally contracted Cl (CCI) method of Siegbahn . Two sets of calculations were performed, which differed in the choice of the reference configurations. In the first set the reference space was chosen as the CASSCF CSFs with coefficients larger than 0.1 around equilibrium. For the state this gave seven reference... 

Audit and inspection functions, which support the control of the manufacturing of products, for instance, for review by an external contract laboratory. 

Do not use for externally contracted diseases with fever even though accompanied by chills. 

Calibration should be traceable to national or international standards through an unbroken chain of comparisons. For instrumentation affecting sterility control in aseptic manufacturing facilities this usually involves comparison of values measured with the item of equipment under test, say a particle counter or a pressure differential gauge, with values measured with a standardized device. In many cases this may mean the use of external contract calibration services, with all that this implies in relation to assuring that the contractor s calibration control systems are themselves under good control. 

Ensuring effective communication is vital in the management of corrosion. Appropriate information should be cascaded to appropriate personnel, and written information on hazards, risks, and preventive measures should be provided. Communication is also very important between the identified key players in the organization and the external contracted bodies. 

Equations (8) and (9) define a minimal MRCI approach, with the dimension being only 3Ap. It is both internally and externally contracted and further augmented with secondary functions. For this reason, the approach can be designated as ixc-MRCISD+s. By replacing the summation over the compound index q (i.e., )t 6 C A U fl, (7 6 A i,j, a,b E. A ) in... 

A variety of methods have been developed and tested which exploit features of the physical structure of wavefunctions in order to avoid the shortcomings of brute-force CI(SD), CI(SDTQ) or full Cl calculations. We mention especially internally or externally contracted MR-CI(SD) techniques, full Cl methods in a limited orbital space such as the CAS-SCF, perturbation theory procedures like MP(4), MP(5), etc., " and pair methods like CP-MET (and CCSD), CEPA and CPF. All these methods certainly have their virtues as is obvious from the chapters in this volume.
