Fluoride Uptake and Net Primary Productivity of Selected Crops  [PDF]
P. C. Mishra, S. K. Sahu, A. K. Bhoi, S. C. Mohapatra
Open Journal of Soil Science (OJSS) , 2014, DOI: 10.4236/ojss.2014.411039
Abstract: Crop field soil collected from Sambalpur University campus of Odisha and treated with various fluoride concentrations was used to raise selected local crops. Background concentration of total and leachable fluoride content in soil was 95.19 and 8.89 ppm respectively. At the time of harvest of the crops, the total fluoride content was found to decrease and leachable fluoride content was found to increase both in control and experimental sets. This might be due to the addition of fluoride to soil in the experimental set up as well as availability of background fluoride content in soil and the irrigated water (i.e. 0.5 ppm). The fluoride accumulation in plant tissue increased with increase in the fluoride content in soil. Net Primary Productivity (NPP) of fluoride treated plants decreased in Brinjal by 6.64% - 56.72%, Tomato by 14.46% - 62.24% and Mung by 10.27% - 53.61%, all in 20 - 100 ppm fluoride range. However, NPP of Mustard, Ladies finger and Chili decreased by 15.58% - 61.21%, 12.28% - 52.78% and 40.8% - 90.65% in 10 - 50 ppm fluoride treated sets respectively in 10 - 50 ppm fluoride range. Maize NPP decreased by 12.17% - 61.20% in 20 - 100 ppm fluoride range as Rice NPP decreased by 6.64% - 56.72% in 20 - 100 ppm fluoride range. Pod formation was inhibited at 100 ppm fluoride amended soil in case of Mung, and 50 ppm in Ladies finger, 40 - 100 ppm in Maize and 30 - 50 ppm fluoride amended soil in case of Chilli. Thus, Maize and Chilli are more sensitive to fluoride contamination than other crops. In all the crops NPP decreased with increase in fluoride content in soil with significant decrease in highest concentration of fluoride.

Neurology India , 2003,
Abstract: Intracranial hemorrhage is an uncommon complication of phenylpropanolamine. There is an increasing awareness of this complication in the West. However, to the best of our knowledge there have been no cases reported from India. Here we report a patient who developed Intraventricular hemorrhage following ingestion of Phenylpropanolamine, from which he made an uneventul recovery over the next two weeks.

The magnetization of PrFeAsO$_{0.60}$F$_{0.12} sueprconductor
D. Bhoi,P. Mandal,P. Choudhury,S. Dash,A. Banerjee
Physics , 2010, DOI: 10.1016/j.physc.2011.02.004
Abstract: The magnetization of the PrFeAsO$_{0.60}$F$_{0.12}$ polycrystalline sample has been measured as functions of temperature and magnetic field $(H)$. The observed total magnetization is the sum of a superconducting irreversible magnetization ($M_s$) and a paramagnetic magnetization ($M_p$). Analysis of dc susceptibility $\chi(T)$ in the normal state shows that the paramagnetic component of magnetization comes from the Pr$^{+3}$ magnetic moments. The intragrain critical current density $(J_L)$ derived from the magnetization measurement is large. The $J_L(H)$ curve displays a second peak which shifts towards the high-field region with decreasing temperature. In the low-field region, a plateau up to a field $H^*$ followed by a power law $H^{-5/8}$ behavior of $J_L(H)$ is the characteristic of the strong pinning. A vortex phase diagram for the present superconductor has been obtained from the magnetization and resistivity data.
Field-induced spin-structural transition and giant magnetostriction in Ising chain $α$-CoV$_2$O$_6$
M. Nandi,N. Khan,D. Bhoi,A. Midya,P. Mandal
Physics , 2013,
Abstract: We have investigated the temperature and magnetic field dependence of magnetization, specific heat ($C_p$), and relative sample length change ($\Delta L/L_0$) for understanding the field-induced spin-structural change in quasi-one-dimensional spin chain $\alpha$-CoV$_2$O$_6$ which undergoes antiferromagnetic (AFM) transition below $T_N$$=$15 K. Analysis of $C_p$($T$) shows that an effective $S$$=$1/2 Ising state is realized below 20 K, though the magnetic fluctuations persist well above $T_N$. $C_p$ and the coefficient of linear thermal expansion ($\alpha$) exhibit strong $H$ dependence in the AFM state. We also observe a huge positive magnetostriction [$\Delta L$($H$)/$L_0$] below 20 K which does not show any tendency of saturation up to 9 T. With increasing field, a sharp and symmetric peak emerges below $T_N$ in both $C_p$($T$) and $\alpha$($T$) due to field-induced first order ferrimagnetic/ferromagnetic-paramagnetic transitions. The large value of magnetostriction below $T_N$ suggests strong spin-lattice coupling in $\alpha$-CoV$_2$O$_6$.
3d-4f spin interaction induced giant magnetocaloric e?ffect in zircon-type DyCrO4 and HoCrO4 compounds
A. Midya,N. Khan,D. Bhoi,P. Mandal
Physics , 2013, DOI: 10.1063/1.4819768
Abstract: We have investigated the influence of 3d-4f spin interaction on magnetic and magnetocaloric properties of DyCrO$_4$ and HoCrO$_4$ compounds by magnetization and heat capacity measurements. Both the compounds exhibit complicated magnetic properties and huge magnetic entropy change around the ferromagnetic transition due to the strong competition between ferromagnetic and antiferromagnetic superexchange interactions. For a field change of 8 T, the maximum values of magnetic entropy change ($\Delta S_{M}^{max}$), adiabatic temperature change ($\Delta T_{ad}$), and refrigerant capacity (RC) reach 29 J kg$^{-1}$ K$^{-1}$, 8 K, and 583 J kg$^{-1}$, respectively for DyCrO$_4$ whereas the corresponding values for HoCrO$_4$ are 31 J kg$^{-1}$ K$^{-1}$, 12 K, and 622 J kg$^{-1}$. $\Delta S_{M}^{max}$, $\Delta T_{ad}$, and RC are also quite large for a moderate field change. The large values of magnetocaloric parameters suggest that the zircon-type DyCrO$_4$ and HoCrO$_4$ could be the potential magnetic refrigerant materials for liquefaction of hydrogen.
Giant magnetocaloric effect in magnetically frustrated EuHo$_2$O$_4$ and EuDy$_2$O$_4$ compounds
A. Midya,N. Khan,D. Bhoi,P. Mandal
Physics , 2012, DOI: 10.1063/1.4754849
Abstract: We have investigated the magnetic and magnetocaloric properties of EuHo$_2$O$_4$ and EuDy$_2$O$_4$ by magnetization and heat capacity measurements down to 2 K. These compounds undergo a field-induced antiferromagnetic to ferromagnetic transition and exhibit a huge entropy change. For a field change of 0-8 T, the maximum magnetic entropy and adiabatic temperature changes are 30 (25) J kg$^{-1}$ K$^{-1}$ and 12.7 (16) K, respectively and the corresponding value of refrigerant capacity is 540 (415) J kg$^{-1}$ for EuHo$_2$O$_4$ (EuDy$_2$O$_4$). These magnetocaloric parameters also remain large down to lowest temperature measured and are even larger than that for some of the potential magnetic refrigerants reported in the same temperature range for a moderate field change. Moreover, these materials are highly insulating and exhibit no thermal and field hysteresis, fulfilling the necessary conditions for a good magnetic refrigerant in the low-temperature region.

Lakshmikanti Bhoi, Pramod Chandra Mishra
Open Journal of Soil Science (OJSS) , 2012, DOI: 10.4236/ojss.2012.22024
Abstract: The utilization of cattle and poultry manure as organic fertilizer improves soil productivity, but arsenic contaminated poultry dung may interfere in soil metabolism and soil fertility. The study was conducted to assess the effects of poultry dung as well as arsenic contamination on soil properties in 1%, 3% and 5% poultry dung amended soil and 1, 5 and 10 ppm sodium arsenite contaminated soil. pH and conductivity were found to be increasing with increase in poultry dung in soil. Other chemical parameters like nitrate, phosphate and organic carbon were found higher in poultry dung amended soil than that of arsenic contaminated soil. Soil bacteria, CO2 evolution and enzymatic activities like amylase, invertase and dehydrogenase were also found higher in poultry dung amended soil suggesting the effectiveness of poultry dung in enhancing soil productivity, even if it was contaminated by As through feed additive.
