Broad-line region

We find four galaxies without direct evidence of an optical broad line region (Se3rfert 2, LINER, or HE region type nuclei) to have very red J-H and H-K colors in our smallest apertures (t3rpicaUy 1 arcsecond diameter) which may indicate the presence of dust-enshrouded active nuclei. These are IRAS 05189-2524, IRAS 12071-0444, UGC 5101, wd IRAS 08572-1-3915. 

Of the NLRGs, SCR 184.1 and 219 have strong, broad Paa lines, zind SCR 22S has a broad component. Figure 1 shows the Paa line in SCR 184.1 as an example. These are clear cases of NLRGs with buried broad-line regions. 

These results imply that at least half of a sample of radio-loud AGN will have broad-line regions, unifying many NLRGs with BLRGs and RLQs, irrespective of the precise unification model. These results are quite consistent with the orientation-unification sdieme. 

Abstract. The potential of mid-infrared imaging, at a resolution of 0.5" or betta, as a poweifril tool in unravelling the complex environments in the vicinity of active galactic nuclei is discussed in the li t of new data on the Seyfert nucleus in NGC 1068. ha particular, we examine the growing body of evidence that the extinction of the broad-line region in NGC 1068 has its origins in an extended molecular disk and b the result of obscuration at 100 pc from the AGN.

There are hundreds of primary battery manufacturers, most of which are limited to a specialty product or a limited national market. However, a number of multinational battery suppHers have manufacturing faciUties in many countries and a broad line of products. Table 4 Hsts the companies having sales of primary batteries of greater than 100 million per annum together with the regions of their headquarters and their product lines. 

T] is in general greater than T2. This difference can in part be a consequence of the slower modes of polymer motion, which are characterized by correlation times sufficiently long that they do not contribute significantly to T] but do to T2. It is therefore important, in terms of describing the fine structure of the non-crystalline regions, to understand the type motions which contribute to T2 and to develop a rationale for the relatively broad lines that are observed for most crystalline polymers. 

The continuity of the linewidth over a large temperature range, above room temperature, that has previously been reported (IJ) and is further detailed here does not reveal any change in the vicinity of the a transition region (80-100°C). Major changes are found in broad line proton NMR experiments, which measure linewidths or second moments. ( ) There is, however, no discrepancy between these results since the a transition is a property of the crystalline regions. The proton measurements... 

Subnormal V02+ complexes (93) of SBs derived from 2-hydroxynaphthaldehyde and o-aminophenol and some substituted derivatives have also been obtained.765 The ESR spectra of the complexes (93 R = R = R" = H R = Cl, R = R" = H) in polycrystalline solids at room temperature exhibit two parallel lines, two perpendicular lines and a broad line around 1600 G due to the AM% = 2 transition. At 77 K, both high- and low-field spectra exhibit hyperfine splittings. Several complexes of type (93) were also studied by Carlisle et al. (Table 41, 27-34).766,767 v(V=0) values of complexes (93) lie in the range 955-1000 cm-1 and the compounds exhibit only one d-d band in the region 620-700 nm. As in the case of (91 R = R = H), on treatment of compound (93 R = R = R" = H) with phen the dimer is broken and a mixed-ligand complex is obtained.765... 

It is important to point out that the observed two-component EPR spectra are an intrinsic property of the lightly doped LSCO and are not due to conventional chemical phase separation. We examined our samples using x-ray diffraction, and detected no impurity phases. Moreover, the temperature dependence of the relative intensities of the two EPR signals rules out macroscopic inhomogeneities and points towards a microscopic electronic phase separation. The qualitatively different behavior of the broad and narrow EPR signals indicates that they belong to distinct regions in the sample. First we notice that the broad line vanishes at low temperatures. This... 

To elucidate the phase structure in detail it is necessary to characterize the molecular chain conformation and dynamics in each phase. However, it is rather difficult to obtain such molecular information, particularly of the noncrystalline component, because it is substantially amorphous. In early research in this field, broad-line H NMR analysis showed that linear polyethylene crystallized from the melt comprises three components with different molecular mobilities solid, liquid-like and intermediate molecular mobility [13-16]. The solid component was attributed to molecules in the crystalline region, the liquid component to... 

The study of the phase structure of semicrystalline polymers, particularly that of the interfacial region, is of foremost importance, since it has an intimate relationship with the macroscopic properties of polymers. Many techniques have been used to study this problem. To determine the mass fraction of each phase of the three-phase structure, such techniques as H broad-line NMR or Raman...
