Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-02) Singh, Rakesh Kumar; Saxena, RakeshHoneycomb structures are stiff and light weight composite structures which show good energy absorption. Hierarchical honeycombs which are bio-inspired innovative form of honeycomb, are used for energy absorption applications. Sub-structure geometry affects the crashworthiness of hierarchical honeycombs. In the present investigation, crushing of vertex based hierarchical honeycomb with regular polygonal (n=3,6,9,12,15) and circular sub-structures is using non linear explicit finite element code LS-DYNA in both in-plane and out of plane direction crushing. Effect of different sub-structure geometry on crashworthiness of vertex based hierarchical honeycomb is studied. Further a parametric analysis is performed to investigate the effect of sub-structure size on crashworthiness of hierarchical honeycombs, for each sub-structure’s geometry. To investigate the effect of crushing velocity on energy absorption similar analyses are performed at higher crushing velocity. In case of in-plane crushing, vertex based hierarchical honeycomb with large sized triangular sub-structure is found to have best energy absorption compared to other hierarchical honeycombs. While in case of out of plane crushing, vertex based hierarchical honeycomb with small sized hexagonal sub-structure is found to have better energy absorption among compared to other hierarchical honeycombs. An improvement in energy absorption of hierarchical honeycombs is found in both in-plane and out of plane crushing at higher crushing velocity.ThesisItem Open Access Relative Screening Of Some Brassica Germplasm Against Athalia Proxima Klug And Lipaphis Erysimi Kalt. And Their Manageent With Safer Insecticides(CSA University of Agriculture and Technology;Kanpur, 2006) Singh, Rakesh Kumar; Verma, R.A.ThesisItem Open Access STUDIES ON PREVALENCE AND EFFECT OF COW URINE (GO-MUTRA) IN CONTROL OF HAEMONCHOSIS IN GOAT(Birsa Agricultural University, Kanke, Ranchi, Jharkhand, 2008) Singh, Rakesh Kumar; Deb, A. R.The present experiment was conducted to find out the status and impact of H. contortus (helminth parasite) in goats to evaluate the therapeutic efficacy of cow-urine (Go-mutra) against natural infection of haemonchosis in goats by observing the treatment effects followed by EPG, different haematological parameters and subsequently their body weight changes and the results obtained have been summarized as follows:- The overall prevalence of Haemonchus spp. in goats was observed to be 36.85 per cent. There was non-significant differences in the prevalence of Haemonchus spp. infection in goat reared on different managemental conditions. Age-wise prevalence of Haemonchus spp. infection in goats indicated that there was non significant difference during 1st and 2nd year. Sex-wise prevalence of Haemonchus spp. infection, it was observed that female goats had higher degree of infection than males. Breed-wise prevalence of Haemochus spp. infection in goats indicates Black Bengal goats (37.14%) were more susceptible to infection than Beetal (33.96%), Jamunapari (27.03%) and Barbari (13.64%). The efficacy of cow-urine (Go-mutra) in Haemonchus spp. infected goats were assessed by applying EPG method reveal significant differences in different groups of goats. The haematological profiles of experimental group of goats during H. contortus infection and treatment with Go-mutra was observed that Hb per cent in blood samples of treated goats was significantly higher than infected untreated control goats but there was significantly increased lymphocyte per cent in control group of goats on different days of infection compared with Go-mutra treated goats. The haematological values of experimental goats during haemonchosis and treated with cow-urine, it was observed that significantly increased percentage in Lymphocyte and Eosinophil in control group than treated goats however, The Neutrophil per cent and Moncocyte per cent were almost unchanged during infection in all the group of goats. The goats having haemonchosis and treated with Go-mutra showed higher gain however, in infected untreated control group there was no desire improvement in the body weight gain. Based on the results of this study it could be concluded that:- Cow-urine (Go-mutra) long term treatment in Haemonchus spp. infection (in goats) was found to resistrict the infection to a limited degree. Due to high cost of Go-mutra, the treatment was found uneconomical. Go-mutra may be a very good supportive therapy along with specific anthelmintic preparation if given, for combating haemonchosis in goats. For evaluating the therapeutic efficacies of Go-mutra for parasitic infection, the more detail studies will be required.
