[en] Criteria for the uniform approximability in R^N, N≥2, of the gradients of C¹-subharmonic functions by the gradients of similar functions that are harmonic in neighbourhoods of a fixed compact set are obtained. The semiadditivity of the capacity related to the problem is proved and several metric conditions for the approximation are found. An estimate of the flux of the gradient of a subharmonic function in terms of the capacity of its 'sources' and a theorem on the possibility of a C¹-extension of a subharmonic function in a ball to a subharmonic function on the whole of R^N are established

[en] Take a system with the following simplifying assumptions: 1) The percentage annual load growth rate is constant. 2) The largest unit in any one year has a capacity corresponding to 1/N of system peak demand in that year. Thus, bigger units are being installed continuously as the system grows.

[en] The present work attempts to systematically investigate micro-mechanism of deformation in amorphous alloys in term of free volume and then searching for an applicable parameter to assess the global plasticity. It has been found that the fragility index (m) is closely related to the plastic deformation capacity. In particular, they satisfy an equation that $\mathrm{\nu <!--\; ??\; -->}=0.7-<!--\; ???\; -->22/(0.4\mathrm{m}+42)$ or $\mathrm{\nu <!--\; ??\; -->}=0.275\mathrm{l}\mathrm{o}\mathrm{g}(m)-<!--\; ???\; -->0.121$ (where v is poisson’s ratio which is an effective parameter to characterize plasticity ). This indicates that high m as well as large v might be considered to be a good indicator of great overall plasticity for amorphous alloys. However, when identifying whether the equation applies to each classification of amorphous alloys, some shows deviation from the relation and even few appear opposite tendency. Finally, these phenomena have been explained by characteristic distribution of free volume and which provides useful clues for improving the plastic deformation ability. (paper)

[en] In this study, the hydroxyapatite (HAp) nanopowders prepared by chemical precipitation method were used as the adsorbent, and the potential of HAp nanopowders for phenol adsorption from aqueous solution was studied. The effect of contact time, initial phenol concentration, pH, adsorbent dosage, solution temperature and adsorbent calcining temperature on the phenol adsorption, and the adsorption kinetic, equilibrium and thermodynamic parameters were investigated. The results showed that the HAp nanopowders possessed good adsorption ability to phenol. The adsorption process was fast, and it reached equilibrium in 2 h of contact. The initial phenol concentration, pH and the adsorbent calcining temperature played obvious effects on the phenol adsorption capacity onto HAp nanopowders. Increase in the initial phenol concentration could effectively increase the phenol adsorption capacity. At the same time, increase in the pH to high-acidity or to high-alkalinity also resulted in the increase in the phenol adsorption capacity. Increase in the HAp dosage could effectively increase the phenol adsorption percent. However, the higher calcining temperature of HAp nanopowders could obviously decrease the adsorption capacity. The maximum phenol adsorption capacity was obtained as 10.33 mg/g for 400 mg/L initial phenol concentrations at pH 6.4 and 60 deg. C. The adsorption kinetic and the isotherm studies showed that the pseudo-second-order model and the Freundlich isotherm were the best choices to describe the adsorption behaviors. The thermodynamic parameters suggested that the adsorption of phenol onto HAp was physisorption, spontaneous and endothermic in nature

[en] An efficient link-removal strategy, called the variance-of-neighbor-degree-reduction (VNDR) strategy, for enhancing the traffic capacity of scale-free networks is proposed in this paper. The VNDR strategy, which considers the important role of hub nodes, balances the amounts of packets routed from each node to the node's neighbors. Compared against the outcomes of strategies that remove links among hub nodes, our results show that the traffic capacity can be greatly enhanced, especially under the shortest path routing strategy. It is also found that the average transport time is effectively reduced by using the VNDR strategy only under the shortest path routing strategy

[en] This article addresses a key question emerging from this project based at the University of Minnesota: the fundamental capacity of government to engage in “dynamic oversight” of emergent technologies. This conception of oversight requires additional or new types of capacity for government agencies that must arbitrate conflicts and endow any outcomes with necessary democratic legitimacy. Rethinking oversight thus also requires consideration of the fundamental design and organizational capacity of the regulatory regime in the democratic state.

[en] Malaysia has fully utilised an Integrated Nuclear Security Support Plan (INSSP) to develop its capacity and capability to implement nuclear security requirements as defined by the IAEA. The plan was designed, developed and mutually agreed upon by all relevant national stakeholders at an early stage so as to ensure its successful implementation in the country. This was carried out by considering the current situation and the envisaged implementation programme as well as the country’s political perspective on nuclear security. It is certainly worth noting that the key to the successful implementation of the INSSP does not rest only on a single agency in the country. It requires the support and committed participation from other national stakeholder entities. Malaysia is now ready for its INSSP to be revised and amended accordingly, in line with the new Nuclear Security Support Plan 2014-2017. (author)
