Study on Leadership Qualities of Supervisory Officers (Divisional / Institution Heads) in ICAR Institutes

Leadership is the role and status of one or more individuals in the structure and functioning of group organizations which enable & to meet a need or purpose, through co-operation of the group members. The ICAR is an apex body with a multitude of research institutes under its realm. The organization is manned by scientific staff of different cadres, prescribed by hierarchical set-up. The leadership qualities of the immediate supervisors have a direct bearing on the productivity of the scientists in succession, which in turn determine the efficiency of technology flow and its transfer to the client system in the field. The present study was undertaken to assess the leadership qualities of supervisory level officers in the hierarchy. More than half of respondents (53.63 %) opined that the immediate supervisors possessed professional knowledge and expertise only to some extent, while 65.22 % said that the level of planning was largely top down, implying a bureaucratic approach. About 42.02 % said that considerable scope was given by superiors to act independently and 56.52 % reported of motivating the staff substantially to achieve higher level of performance. Ademocratic leadership, involving a bottom-up approach must be fostered within the limits of official hierarchy to enable the individuals in the organization to show case their skills and ability for enhancing the productivity of the organization

Ovarian cancer: emerging concept on cancer stem cells.

Emerging evidence suggests that the capacity of a tumor to grow and propagate is dependent on a small subset of cells within a tumor, termed cancer stem cells. In fact, cancer cells, like stem cells, can proliferate indefinitely through a dysregulated cellular self-renewal capacity. Cancer stem cells may originate due to the distribution into self-renewal and differentiation pathways occurring in multi-potential stem cells, tissue-specific stem cells, progenitor cells and cancer cells. Recent studies have shown that ovarian cancer also contains stem cells or tumor-initiating cells. Moreover, ovarian serous adenocarcinomas were disaggregated and subjected to growth conditions to select for self-renewing, non-adherent spheroids previously shown to be derived from tissue stem cells. A recent study showed that epithelial ovarian cancer was derived from a sub population of CD44+, CD117+ and CD133+ cells. The existence of cancer stem cells would explain why only a small minority of cancer cells is capable of extensive proliferation of the tumor. In this review, we have discussed the studies on ovarian cancer stem cells along with the molecular pathways that could be involved in these cancer stem cells

Fault Tolerance in Reversible Logic Circuits and Quantum Cost Optimization

Energy dissipation is a prominent factor for the very large scale integrated circuit (VLSI). The reversible logic-based circuit was capable to compute the logic without energy dissipation. Accordingly, reversible circuits are an emerging domain of research based on the low value of energy dissipation. At nano-level design, the critical factor in the logic computing paradigm is the fault. The proposed methodology of fault coverage is powerful for testability. In this article, we target three factors such as fault tolerance, fault coverage and fault detection in the reversible KMD Gates. Our analysis provides good evidence that the minimum test vector covers the 100 % fault coverage and 50 % fault tolerance in KMD Gate. Further, we show a comparison between the quantum equivalent and controlled V and V+ gate in all the types of KMD Gates. The proposed methodology mentions that after controlled V and V+ gate based ALU, divider and Vedic multiplier have a significant reduction in quantum cost. The comparative results of designs such as Vedic multiplier, division unit and ALU are obtained and they are analyzed showing significant improvement in quantum cost
