H 2 O, and [Co(H 2 L)(HL) 2 .1/2 EtOH] were prepared and identified by spectral techniques and thermogravimetric analysis Derivative thermo gravimetric analysis. The results confirmed that the ligand behaved as neutral tetradentate, bidentate, or monobasic tridentate. Coordination has occurred via carbonyl oxygen (C=O) and N(2)H or (C-S) groups in complex (3). Moreover, complex (3) was more stable than the analogs (1–3). The prepared mononuclear complexes exhibited an octahedral conformation. The ligand and Cr(III), Fe(III), and Co(II) complexes were investigated for their inhibitory action on the growth of Streptococcus pyogenes and Escherichia coli as Gram-positive and negative bacteria, respectively. The results indicated the effective behavior of Cr(III), Fe(III), and Co(II) complexes as being antibacterial compared to the ligand. The in vitro antitumor activity also displayed the potent action of compounds. In addition, it was revealed that the majority of complexes were more effective than their free ligand. Furthermore, molecular docking implementation demonstrated the intriguing possible interactions of the ligands and complexes with amino acid active sites of the ribosyltransferase moiety (PDB ID).","PeriodicalId":235365,"journal":{"name":"Counting-Out Rhymes","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1980-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129541623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While many researchers believe that magnetic processes are responsible for cool evolved stellar winds, existing MHD and Alfvén wave-driven wind models have magnetic fields that are essentially radial and tied to the photosphere. The clumped magnetic wind scenario is quite different in that the magnetic flux is also being carried away from the star with the wind. We test this clumped wind hypothesis by computing continuum radio fluxes from the ζ Aur semiempirical model of Baade et al., which is based on wind-scattered line profiles. The radio continuum opacity is proportional to the electron density squared, while the line scattering opacity is proportional to the gas density. This difference in proportionality provides a test for the presence of large clumping factors. We derive the radial distribution of clump factors (CFs) for ζ Aur by comparing the nonthermal pressures required to produce the semiempirical velocity distribution with the expected thermal pressures. The CFs are ∼5 throughout the sub-sonic inner wind region and then decline outward. These implied clumping factors lead to excess radio emission at 2.0 cm, while at 6.2 cm it improves agreement with the smooth unclumped model. Smaller clumping factors of ∼2 lead to better overall agreement but also increase the discrepancy at 2 cm. These results do not support the magnetic clumped wind hypothesis and instead suggest that inherent uncertainties in the underlying semiempirical model probably dominate uncertainties in predicted radio fluxes. However, new ultraviolet line and radio continuum observations are needed to test the new generations of inhomogeneous magnetohydrodynamic wind models.","PeriodicalId":235365,"journal":{"name":"Counting-Out Rhymes","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1980-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132391480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
