AbstractThe interplay between groups and graphs have been the most famous and productive area of algebraic graph theory. In this paper, we introduce and study the graphs whose vertex set is group G such that two distinct vertices a and b having di erent orders are adjacent provided that o(a) divides o(b) or o(b) divides o(a).

Steel Re-Rolling mill is the second most important steel forming industry in India. The manufacturing process of steel re-rolling from ingots to finished products has high energy consumption and it directly affects productivity and manufacturing cost. Measuring the productivity of the process can unleash the low productive process, which leads towards rectification for increasing the productivity of lean area. The productivity of Steel Re-Rolling mill is measured by Performance Objective – Productivity model. Key performance areas were identified by intensive survey and process of prioritization was carried out. The actual values of the Key performance Areas of the system were compared with the objectivated values of the system. The outcomes lead to Productivity Index of the system, sub-system and key performance areas of the process revealing the areas with low-performance index which have the highest impact on productivity of the process. The energy subsystem is having the lowest performance index and is the main source of loss and recommendations are made to increase the productivity of energy sub-system.

Drepanopus forcipatus and Calanus australis are key planktonic copepods on the southern Patagonian shelf. Their feeding and reproductive patterns and population status were investigated during late summer, when environmental conditions may be critical. The presence of food in the gut and food-pellet length were recorded in adult females and the most abundant copepodite stages. Diet composition was also studied in adult females. Female reproductive status was evaluated by gonad staging. Despite generally low feeding conditions and decreasing seasonal temperature, both copepods fed to some degree. The most numerous copepodites and adult females of both species showed similarly low feeding activity. About half of the adult females of the two species and C5s of C. australis contained food in their guts, but the proportion of fed C4-females of D. forcipatus was much lower. All copepods were generally feeding at low or intermediate levels. Gonad stage distribution and population structure showed low but still ongoing reproduction in both species. Gut content findings suggest a preference for smaller nanoplanktonic particles, especially dinoflagellates by D. forcipatus, and for autotrophic prey, particularly large diatoms by C. australis. The feeding and reproduction patterns of the two copepods were likely influenced by the distributions of potential food resources and temperature.
