Dressing Materials

The aim of this paper is to introduce novel dressing with Mikania Micrantha for quick blood clotting and wound healing. When epidermis of human skin is cut or scrapped, sometimes too much bleeding occurs. Excessive bleeding may cause death, if bleeding is not stopped immediately. To promote blood clotting & wound healing natural based bio materials are still insufficient in medical textile sector. To fill up this scarcity, woven fabric treated with Mikania micrantha leaf juice & leaf powder was examined. M. micrantha exhibits good blood clotting time in comparison with available dressing materials. Woven fabric (bandage) that contains M. micrantha can be used for cut wounds healing purpose. The experiments were carried out in environment friendly way which indicates the production & processing of these dressing materials can have enormous contribution to sustainable operations and products.

Herein, we report the dissolution of CN in environment-friendly methane sulfonic acid and the homogeneous photocatalysis driven by CN for the first time with the activity boosted up to 10-times, comparing to the heterogeneous counterparts. Moreover, facile recycling and reusability, the <a>hallmark</a> of heterogeneous catalysts, were kept for the homogeneous CN photocatalyst via reversible precipitation using poor solvents. It opens new vista of CN in homogeneous catalysis and offers a successful example of polymeric catalysts in bridging gaps of homo/heterogeneous catalysis.

The municipality of Marituba, Metropolitan Region of Belém - RMB, has suffered environmental impacts due to irregularities in the landfill operation implemented in 2015, which triggered social impacts perceived by all the population, including neighboring municipalities, such as Ananindeua and Belém Protests were carried out by the Movement Outside the Garbage that is constituted by the dwellings of the surrounding neighborhoods to the place where the embankment is located, of owners of commercial activities linked to the tourism and Non Governmental Organizations that interrupted several times the transit of the main route that interconnects the seven municipalities of the RMB and the entrance of the embankment, in order to draw the attention of the municipal public power to the problems that the population would have been facing ever since. From this, the following questions arose: What social impacts would people be making in these protests? Would such problems be directly related to the activities carried out in the landfill? And finally, what are the actions of the public authority and the company that manages the enterprise in the management of these social impacts? The relevance of this study concerns not only the identification of social impacts considering the fragility of this approach in the Environmental Impact Studies and concomitantly in the Reports of Environmental Impacts, but also, from the point of view of the debate about the licensing process of enterprises of this nature and employment and the need for the joint use of environmental and urban policy instruments, considering that RMB municipalities have not yet used sustainable alternatives for the reduction of solid waste produced in their territories, as well as the reduction of environmental impacts caused by dumps , and in the case of Marituba, of the landfill that operates outside the standards established by the Brazilian Association of Technical Standards - ABNT, which is responsible for the management and treatment of solid waste and the National Policy on Solid Waste - PNRSN.
