La1-xSrxAlO3 (x=0 to 0.4) perovskite materials were synthesized by the reverse strike co-precipitation method and their soot oxidation activity was evaluated. All the catalysts synthesized were characterized using XRD, BET specific surface area, FESEM and XPS techniques. As analyzed by XRD, La1-xSrxAlO3 <...

The reverse logistics (RL) concept has become increasingly popular due to the rising socio-environmental crisis, encompassing climate changes, pollutions and numerous health issues caused by pollutions. Therefore, a bibliometric analysis was conducted on RL guide future research. This study utilised VOSviewer software conduct from 1995 2020. Precisely, 1146 papers were retrieved analysed identi...

Calcium carbonate nano-particles were synthesized by a reverse micro-emulsion method at room temperature with Tween® 80 and Span® 80 as co-surfactants. The nano-particles synthesized were surface modified by stearic acid. An important operating variable in the Span 80-Tween 80/toluene/water reverse micro-emulsion system, the ω-value (water/surfactant molar ratio) was i...

Reverse transcription is the central defining feature of HIV-1 replication. We previously reported that the cellular eukaryotic elongation factor 1 (eEF1) complex associates with the HIV-1 reverse transcription complex (RTC) and the association is important for late steps of reverse transcription. Here we show that association between the eEF1 and RTC complexes occurs by a strong and direct int...

MOTIVATION Advances in molecular biological, analytical and computational technologies are enabling us to systematically investigate the complex molecular processes underlying biological systems. In particular, using high-throughput gene expression assays, we are able to measure the output of the gene regulatory network. We aim here to review datamining and modeling approaches for conceptualizi...

The conventional wisdom regarding the political consequences of large reductions of budget de…cits is that they are very costly for the governments which implement them: they are punished by voters at the following elections. In the present paper, instead, we …nd no evidence that governments which quickly reduce budget de…cits are systematically voted out of o¢ ce in a sample of 19 OECD countri...

Abstract In this study, a mathematical model is proposed for CO2 separation from N2/CO2 mixtureusing a hollow fiber membrane contactor by various absorbents. The contactor assumed as non-wetted membrane; radial and axial diffusions were also considered in the model development. The governing equations of the model are solved via the finite...

The paper reports an empirical study of the factors affecting burden sharing among OECD’s 22 DAC members in ‘bankrolling’ the multilateral aid agencies. These are the UN agencies, World Bank’s IDA and non-IDA programmes, regional development banks, European Community, and other multilateral agencies that include the Global Environmental Facility and the Montreal Protocol on environment. Annual ...
