Matching Preclusion and Conditional Matching Preclusion Problems for Twisted Cubes

The matching preclusion number of a graph is the minimum number of edges whose deletion results in a graph that has neither perfect matchings nor almost-perfect matchings. For many interconnection networks, the optimal sets are precisely those induced by a single vertex. Recently, the conditional matching preclusion number of a graph was introduced to look for obstruction sets beyond those induced by a single vertex. It is defined to be the minimum number of edges whose deletion results in a graph with no isolated vertices that has neither perfect matchings nor almost-perfect matchings. In this paper, we find the matching preclusion number and the conditional matching preclusion number for twisted cubes, an improved version of the well-known hypercube. Moreover, we also classify all the optimal matching preclusion sets

Role of NGOs in Good Governance

Voluntary organisations play a vital role in shaping and implementation of participatory democracy. The main role of NGOs has been in enforcement provision. Their "gap-flling‟ role and independence from government has allowed them to implement innovative approaches that can serve as models for government and the public enforcement system. In this sense, NGOs should continue doing what they already do best in order to become a useful laboratory for government. Mainstreaming such successful innovations in cooperation with government thus becomes an enforcement of human rights process par excellence; going beyond the individual and community level, this type of scaling up can become part of enforcement of human rights sector reform, involving all levels and actors, and incorporating NGOs as policy-partners and advisors. NGOs can become acknowledged innovators in the public interest, with a constant eye on adoption by bigger and more powerful actors and on enhancing the capacity of claimants

A Review of Corporate Sustainability Reporting: Global and National scenario

Global concerns of climate change, poverty, human rights violations, and legal compliances have entailed corporate to pay attention towards social and environmental issues. Company‟s responsibility towards environment and social are reflected in their sustainability report (SR). The current sustainability reporting movement emerged in the US during the late 1980s, in response to the US 1987 Superfund Amendments and Reauthorization Act. Sustainability reporting gave multiple benefit of improvement in financial performance, stakeholder relationships, risk management, investor relationships, and Identification of new markets. However, the progress of sustainability reporting in India was slow, but a significant and sound start has been made. Adopting the principles of sustainability companies could make both comparative as well as competitive advantage over other. At present, there are good institutional setup and skilled human resource in India for developing Sustainability Reports. In this regard, there are no excuses for Indian businesses to not include them in their portfolio. With this Indian corporate show great interest in sustainability and sound growth has already been observed. Reporting practices will make companies to long term profitable, ethical, brand image and resourceful. It is proposed that a good Sustainability Report should give a holistic view of business and help the organization to design its strategy and prepare it suitably for different kinds of business cycles

Effectiveness and scaling trends of leakage control techniques for sub-130nm CMOS technologies

This paper compares the effectiveness of different leakage control techniques in deep submicron (DSM) bulk CMOS technologies. Simulations show that the 3-5x increase in IOFF/µm per generation is offsetting the savings in switching energy obtained from technology scaling. We compare both the transistor IOFF reduction and ION degradation due to each technique for the 130nm-70nm technologies. Our results indicate that the effectiveness of leakage control techniques and the associated energy vs. delay tradeoffs depend on the ratio of switching to leakage energies for a given technology. We use our findings to design a 70nm low power word line driver scheme for a 256 entry, 64-bit register file (RF). As a result, the leakage (total) energy of the word line drivers is reduced by 3x(2.5x) and for the RF by up to 35%(25%) respectively

Objective: Our study aimed to characterize and optimize the physico-chemical properties which render the high yield of intracellular orange fluorescent pigment (IOFP) and its antibacterial activity against clinical pathogens.Methods: Intracellular orange fluorescent pigment (IOFP) extracted from Bacillus endophyticus AVP-9(Kf527823) a rhizobacteria of chilli agricultural field using different solvent systems, fractioned by TLC and analyzed for absorption maxima. Purified pigment was screened for antimicrobial activity against clinical pathogen, Optimization of cultural conditions for maximizing the yield of pigment and compared the yield in different broth media.Results: AVP-9(Kf527823) showed circular, large orange color colonies which fluoresced orange under U. V light,. Intracellular pigment affectively extracted in acetone showed a bright fluorescent orange spot on the TLC plate, and absorption maxima at 493 nm. Antibacterial activity of isolated pigment showed highest zone of inhibition against E. coli and least to Pseudomonas. Maximum yield of the pigment was achieved in modified nutrient brot (MNB)h medium containing 2% w/v nutrient broth containing1% w/v glucose,1% w/v peptone and0.5% methionine at 35 °C and pH 7.0 with 48 h of incubation period. The yield was observed maximum in MNB. Compared to lactose broth, Tryptone soya broth and peptone water.Conclusion: Bright fluorescent orange pigment of Bacterium avp-9(Kf527823) with absorption maxima at 493 indicating that the pigment shows the characters of carotenoids. Yield maximum in MNB and its potential antibacterial activity needs further investigation for pharmaceutical applications

A comparative study of radical radiotherapy with weekly paclitaxel versus radical radiotherapy with weekly cisplatin in the management of locally advanced squamous cell carcinomas of head and neck

Background: Concurrent chemo radiation is standard of care in locally advanced squamous cell carcinomas of head and neck. Single agent Cisplatin either weekly or three weekly is commonly used concurrently with radiation. The present study aims to evaluate the response rate and toxicity of radical radiotherapy with weekly paclitaxel and cisplatin in head and neck cancers.Methods: This is a prospective double arm study in which sixty patients with histologically proved squamous cell carcinomas registered in our department were accrued into the study with thirty patients in each arm. All patients were treated using Theratron phoenix 780 cobalt unit with a dose of 66 Gy in 33 fractions. The patients were randomized to receive 40 mg/m2 of weekly cisplatin or 40 mg/m2 of weekly Paclitaxel concurrently with radiation. The response to the therapy was assessed six weeks after completion of treatment. The statistical analysis was done using SPSS software.Results: In cisplatin group 18 patients achieved complete response and 12 patients achieved partial response whereas in Paclitaxel group 21 patients achieved complete response and 9 patients achieved partial response. However in paclitaxel arm the incidence of radiation dermatitis, mucositis, dysphagia and laryngitis are slightly higher compared to cisplatin group.Conclusions: The weekly paclitaxel concurrent with radiation is a feasible alternative to weekly cisplatin in locally advanced squamous cell carcinomas of head and neck
