    Notes: Thermally induced reactions in TiN/Al–Cu/TiN have been investigated. It is observed that the amount of the reactions is different at the two interfaces between Al–Cu and TiN. While there is minimal reaction between Al–Cu and the TiN overlayer, the reaction between Al–Cu and the TiN underlayer increases the sheet resistance of Al–Cu by as much as 15%. It is further shown that the asymmetric reactions are most likely caused by the different degree of (111) texture of TiN grown on amorphous SiO2 and textured, polycrystalline Al–Cu. © 1995 American Institute of Physics.

    Notes: IgG1 is cleaved in vitro by granulocyte elastase into Fc and Fab fragments. The elastase-specific Fe fragment has been previously detected in vivo. Biological activity of the fragments has been described in modulating neutrophil oxidative metabolism and enzyme release. To investigate further effects granulocyte chemotaxis(CT) was tested. The CT was assayed in Boyden chambers and the chemotactic index (CI) was calculated which represents the mean distance travelled by the activated cells.Stimulation of leucocyte CT by casein, activated scrum and FMLP gives maximal values of Δ CI = 46.7, 26.4 and 7.1 μm, respectively. Native IgG1 and the elastase-produced IgG fragments do not stimulate leucocyte CT.FMLP-stimulated CT is specifically inhibited by the elastase-produced Fc fragments. Addition of 7 nmol Fc to stimulus concentrations of 16 to 125 nM FMLP results in total inhibition of chemotaxis demonstrated by CI values which are lower than those for unstitmulated cells. The inhibition of CT is concentration dependent in the range of 2 to 7 nmol Fc/106PMN.Number and affinity of FMLP receptors are not incipience by Fc fragments, so Fc binds neither to FMLP nor the FMLP receptor.CT stimulated by casein shows a large portion of chemokinesis. Only at suboptimal casein concentrations do Fc and IgG have an Inhibitory effect on CT (0.63 mg casein /ml. 10 nmol peptide/106 PMN).C5a-stimulaicd CT is not influenced by IgG or IgG fragments which indicates that the samples are not cytotoxic. So the FMLP and casein-stimulated CT is specifically inhibited by the elastase-produced Fc fragments in a low concentration range.

    Notes: This investigation analyzed, in a cross-sectional study, the possible relationship between gingival crevicular fluid (GCF) elastase-like protease (ELP) levels and the periodontal clinical parameters or the presence of specific bacteria in subgingival plaque. A total of 388 periodontal sites from 8 adult periodontitis patients were examined for plaque index (P1I), gingival index (GI), pocket depth (PD) and alveolar bone loss (ABL). GCF ELP levels were determined as ELP alpha-1 protease inhibitor (ELP-α1-PI) complex levels with a commercially available ELISA. Subgingival plaque samples were tested for the presence of Bacteroides gingivalis, B. intermedius and Actinobacillus actinomycetemcomitans by indirect immunofluorescence (IF) microscopy. GCF ELP-α1-PI levels were then correlated with clinical periodontal indices and proportions of IF-positive bacteria per site. Statistically significant positive correlations were found between GCF ELP-α1-PI concentrations and subgingival Bacteroides proportions. When the sites examined were analyzed depending on the level of each clinical parameter, the levels of these correlations changed. A. actinomycetemcomitan correlated highly (r = 0.716) with ABL for sites with low GI score. The correlations between GCF ELP-α1-PI and B. gingivalis (r = 0.642) or B. intermedius (r = 0.774) were the highest for ABL ≤ 20% and PD ≤ 3 mm, respectively. The strong association between GCF ELP-α1-PI concentrations and subgingival bacteria previously associated with advancing periodontitis indicates that measurement of GCF ELP-α1-PI concentrations may be useful in the evaluation of periodontal sites, especially those with very little or no tissue destruction.

    Notes: [Auszug] Experimental information about the process, however, is meagre and sometimes conflicting. In the turbulent region, Martinelli et al.2"* and Marchant4 found no difference in heat transfer between steady unidirectional flow and pulsating flow, but West and Taylor5 reported an increase of 60-70 ...

    Notes: Syria was one of the few areas of medieval Islam where cities emancipated themselves from centralized rule to a certain degree by shaping local self-representative institutions and by transforming “classical” government offices according to their special needs. For nearly two hundred years—from about the second half of the 10th century to the middle of the 12th century—Syrian cities possessed urban heads (ru'asā') and militias of young men (ahdāth) that, in a way, complemented or even replaced the rulers and garrisons representing the Fatimid and Saljuq central governments; in time, they became institutionalized collaborators within the Saljuq regimes. This development is most evident in Damascus and Aleppo, although things evolved differently in the two cities. By gaining the rulers' recognition, the urban forces (ru'asa' and ahdath) not only managed to take over the functions of the police (shurta) and partake in the rulers' military and political tasks, but they also controlled—to a certain degree—the economic, administrative, and financial affairs of the city (these, it will be argued, can be substantiated only with regard to Damascus, not to Aleppo). It is significant, for example, that the Arabic sources reporting on Damascus do not mention the muhiasib, the “classical” official for the urban administration and economy, when there was a ra'īs. Even more striking is the fact that sometimes the ra'īs also functioned as the vizier installed by the ruler. Thus, one can see that the ra'īs, the holder of a local urban office, became a very important member of the central ruling system, normally represented by a foreign-born elite that also supplied the vizier.
