Sectoral harmonics

The ones with m = I divide the sphere into sections with vertical nodal lines, which are called sectoral harmonics. Those are ... 

Fig. A.I. Real spherical harmonics. The first one, Y , is a constant. The coordinate system attached to the unit sphere is shown. The two zonal harmonics, IT and II, section the unit sphere into vertical zones. The unshaded area indicates a positive value for the harmonics, and the shaded area indicates a negative value. The four sectoral harmonics are sectioned horizontally. The two tesserai harmonics have both vertical and horizontal nodal lines on the unit sphere. The corresponding "chemists notations," such as (3z — r ), are also marked.

As a set of minimum standards, ISO 9000 addresses the business community. It was intended for purchasers as a means for them to obtain products and services of consistent quality from their suppliers. In place of purchaser-specified general quality management requirements, ISO 9000 became the common requirement and hence eliminated the need for such requirements. As a consequence, it provides suppliers that meet its requirements with a demonstrable capability that others may not possess and hence such capability becomes a persuasive marketing tool that will increase market share. ISO 9000 was also intended for application to all types of industry and therefore did not contain requirements for any specific industry sector or type of products or services. Partially due to the scope of misinterpretation and the degree to which particular industries have common supplier requirements, certain industry sectors perceived the need for harmonizing such requirements in a form that added to those requirements in ISO 9000. 

Although the UK, and in particular the UK automotive industry, had been at the forefront of the development of non-military quality system standards, harmonization within the automotive sector beyond BS 5750 was believed too difficult to achieve. Using BS 5750 as a baseline only, the UK motor manufacturers continued to develop their own supplementary standards, many of which are still in use today. BS 5750, and its successor ISO 9000, was enforced by the UK automotive industry and no further harmonization took place.

Finally, some of the potential difficulties in allocation are exacerbated by the lack of harmonization, if a sector in one country can plausibly argue that the methodology adopted in another is more favourable. We now consider this final characteristic of the EU ETS. 

Responses were returned from individual pharmaceutical companies through their industry associations and the regulatory agencies in the respective sectors. The complete response was compiled by the USP, and a list of the top-10 excipients was developed as the focal point for initial harmonization efforts, after review by each... 

However, to overcome present barriers, sustainable energy vectors should be developed in a harmonized way, taking into account all possibilities and related technologies, and not be limited to one or few sources. For example, in the transportation sector, several technologies present great potential biomass conversion into biofuels, hydrogen fuel cells, hybrid engines and the exploration of metal... 

If the Fock state basis is used to describe the field state, we find, for the initial state n. 0) = n) 0) with n photons in the fundamental mode and zero photons in the second harmonic mode, that the Hamiltonian H0 splits the Hilbert space into orthogonal sectors. Since Ho is a constant of motion, we have for a given number of photons n the relation...
