Ethnomedicinal plants used in malaria in tribal areas of Odisha, India

The present paper deals with 38 ethnomedicinal plant species belonging to 37 genera and 24 families used for prevention and treatment of malaria by the tribal and indigenous non-tribal communities of Sundargarh, Mayurbhanj, Angul, Balangir, Deogarh and Nuapada districts of Odisha. This first-hand ethnomedicinal information for their therapeutic use against malaria was collected directly from a field survey of 404 remote tribal villages and forest areas of these 6 districts during 2006-2017. Additionally, uses of other 6 plants for the treatment of the same diseases were also recorded from the already published literature on these districts. These plant species are arranged in alphabetical order followed by family, habit, local name(s), locality(ies), field number(s) along with a method of preparation and mode of ethnomedicinal uses in detail

Fabrication and Evaluation of Low Density Glass-Epoxy Composites for Microwave Absorption Applications

In the present work, fabrication and evaluation of low density glass – epoxy (LDGE) composites suitable for absorbing minimum 80 per cent of incident microwave energy in 8 GHz to 12 GHz (X-band) is reported. LDGE composites having different densities were fabricated using a novel method of partially replacing conventional S-glass fabric with low density glass (LDG) layers as the reinforcement materials. Flexural strength, inter laminar shear strength and impact strength of the prepared LDGE composites were evaluated and compared with conventional High density glass-epoxy (HDGE) composites to understand the changes in these properties due to replacement of S-glass fabrics with LDG layers. To convert LDGE structures to radar absorbing structures controlled quantities of milled carbon fibers were impregnated as these conducting milled carbon fibers can act as dielectric lossy materials which could absorb the incident microwave energy by interfacial polarisation. Electromagnetic properties namely loss tangent and reflection loss of carbon fiber impregnated LDGE composites were evaluated in 8 GHz -12 GHz frequency region and compared with HDGE composites. It was observed that both LDGE and HDGE composites have shown loss tangent values more than 1.1 and minimum 80 per cent absorption of incident microwave energy. Thus the results indicates that, LDGE composites can show EM properties on par with HDGE composites. Furthermore these LDGE composite could successfully withstand the low velocity impacts (4.5 m/s) with 50 J incident energy. Due to their ability to show good mechanical properties and light weight, LDGE composites can be used as a replacement for conventional HDGE composites to realise radar absorbing structures

Ethnomedicinal plants used for dental care in Sundargarh, Mayurbhanj, Angul and Balangir districts of Odisha, India

419-424The paper deals with 31 plant species belonging to 29 genera and 20 families comprising 40 ethnomedicinal uses for dental care (tooth ache, tooth decay, pyorrhea, foul smell and as tooth brush) by the different tribal and rural people in Sundargarh, Mayurbhanj, Angul and Balangir districts of Odisha. These uses were compared and cross-checked with the published ethnomedicinal data from Odisha and other states of the country and found that 12 uses of the referred plants had not been reported earlier. These plant species are arranged alphabetically with their botanical names, family and local name(s), followed by the method of uses for dental care along with field collection number(s) and uses cited by earlier workers. </span
