we define minimal cn-dominating graph $mathbf {mcn}(g)$, commonality minimal cn-dominating graph $mathbf {cmcn}(g)$ and vertex minimal cn-dominating graph $mathbf {m_{v}cn}(g)$, characterizations are given for graph $g$ for which the newly defined graphs are connected. further serval new results are developed relating to these graphs.

the aromatic plants are rich in essential oils characterized by a notable antimicrobial activity; for this reason, these substances can be used to delay or inhibit the growth of pathogenic or spoilage microorganisms. in this study, log probability percentage (log p%) of growth of the clostridium botulinum type a spores in brain heart infusion (bhi) broth as affected by various levels of zataria...

We have detected circumstellar absorption lines of the CN and CN Violet and Red System in the spectrum of the post-AGB star HD 56126. From a synthetic spectrum analysis, we derive a Doppler broadening parameter of b = 0.51 ± 0.04 km s, CN/CN= 38±2, and a lower limit of 2000 on CN/CN and CN/CN. A simple chemical model has been computed of the circumstellar shell surrounding HD 56126 that takes i...

discrimination of regenerative cirrhotic nodules of the liver (cn) from hepatocellular carcinoma (hcc) is sometimes difficult. we examined the utility of agnor staining in this context. fifteen cases of hcc and 25 cases of cn were stained by agnor method and the mean agnor number for one hundred nuclei in each case was determined. there was a significant difference between the mean agnor counts...
