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.
Water budgets for freshwater aquaculture ponds with reference to effluent volume  [PDF]
K. K. Sharma, B. C. Mohapatra, P. C. Das, Bikash Sarkar, S. Chand
Agricultural Sciences (AS) , 2013, DOI: 10.4236/as.2013.48051
Abstract:

This paper presents the consumptive water use for freshwater pond aquaculture for semi-intensive carps farming practices. The consumptive use of water includes evaporation loss, seepage loss and water exchanges requirements. The water requirement has been estimated to be10.3 m3/Kg of fish production under present study for semi-intensive culture and with supplemental feeding. Out of which7.6 m3/Kg of fish production is system associated requirement. On an average the evaporation loss from the pond is1498.3 mm/year and seepage loss per year is about1182.60 mm/year. Seepage and water exchange losses recharge the ground water aquifers and if they are treated and recycled, the water use in aquaculture can be reduced significantly. A further reduction in fresh water use in pond aquaculture is possible through development of intensive and superintensive culture systems and aqua feeds.

Lateral fluid percussion injury of the brain induces CCL20 inflammatory chemokine expression in rats
Mahasweta Das, Christopher C Leonardo, Saniya Rangooni, Keith R Pennypacker, Subhra Mohapatra, Shyam S Mohapatra
Journal of Neuroinflammation , 2011, DOI: 10.1186/1742-2094-8-148
Abstract: In this report, we used a rat lateral fluid percussion impact (LFPI) model of TBI to characterize neurodegeneration, apoptosis and alterations in pro-inflammatory mediators at two time points within the secondary injury phase. Brain histopathology was evaluated by fluoro-jade (FJ) staining and terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) assay, polymerase chain reaction (qRT PCR), enzyme linked immunosorbent assay (ELISA) and immunohistochemistry were employed to evaluate the CCL20 gene expression in different tissues.Histological analysis of neurodegeneration by FJ staining showed mild injury in the cerebral cortex, hippocampus and thalamus. TUNEL staining confirmed the presence of apoptotic cells and CD11b+ microglia indicated initiation of an inflammatory reaction leading to secondary damage in these areas. Analysis of spleen mRNA by PCR microarray of an inflammation panel led to the identification of CCL20 as an important pro-inflammatory signal upregulated 24 h after TBI. Although, CCL20 expression was observed in spleen and thymus after 24h of TBI, it was not expressed in degenerating cortex or hippocampal neurons until 48 h after insult. Splenectomy partially but significantly decreased the CCL20 expression in brain tissues.These results demonstrate that the systemic inflammatory reaction to TBI starts earlier than the local brain response and suggest that spleen- and/ or thymus-derived CCL20 might play a role in promoting neuronal injury and central nervous system inflammation in response to mild TBI.Head wounds and brain injuries following blast explosions affect more than 1.2 million Americans annually, including U.S. soldiers involved in combat operations and public safety personnel surviving terrorist attacks. It is estimated that 150-300,000 military personnel from Operation Iraqi Freedom and Operation Enduring Freedom suffered from traumatic brain injury (TBI) [1-3]Despite the increased recognition and prevalence of TBI, the pa
The Effect Of Nutritional Supplementation On Anthropometric Parameters Of Antenatal Women
Mohapatra P,Mohapatra S C,Agrawal D K,Agrawal K N
Indian Journal of Community Medicine , 1993,
Abstract: One hundred forty eight antenatal women resisted from our peri-urban villages of Varanasi city were studied. Seventy were given nutrition supplementation while 78 were kept as matched control (non-supplemented). The supplementation containing 333 k cal, 11 gm protein and 5.6 mg. of iron, when distributed as a€ door step supervised feedinga€ for 120 day produced a significant rise in the anthropometrics parameter. There was a significant increase (p less than 0.001) in the birth weight, crown heel length as well as the head, chest and midarm circumferences of the newborn, proving a positive effect of nutrition supplementation on the anthropometrics parameters of the mother-child dyad.
Missed Opportunity Survey : Proxy Index For Community Participation
Tandon J,Mohapatra S.C,Gupta J.N.P,Mohapatra P
Indian Journal of Community Medicine , 1993,
Abstract: Research question: Can the Missed opportunity Survey methodology be used to evaluate community participation in health programmes? Objectives: 1.To identity hospitals with daily outpatient attendance of at least 200 patients, 2. to apply the Missed Opportunity Survey tool to patients attending various clinics. 3. to evaluate its use in the evaluation of community participation in health programmes/services. Design: Cross-sectional study. Setting: Hospitals with a daily outpatient attendance of at least 200 patients in an urban area. Participants: Patients and attendants of patients attending the outpatient departments and willing to take part in the study, statistical Analysis: Chi square test. Results: The Missed opportunity survey tool showed a statistically significant better community participation to the immunization programme than the maternal & child Health Programme. It also demonstrated that participation in the Tuberculosis Control Programme compared well with the immunization programme. Conclusions: The Missed Opportunity Survey can be used as a surrogate tool for the evaluation of all health programmes.
Effect Of Supplementation On Haematological And Biochemical Parameters During Pregnancy
Mohapatra P,Mohapatra S.C,Agarwal D.K,Agarwal K.N
Indian Journal of Community Medicine , 1988,
Abstract: One hundred forty eight antenatal women were studied as supplemented (70) and non-supplemented (78) groups. The former group received nutritional supplementation in addition, to Iron, Folic acid and calcium tablets, which were given to both the groups. There was significant increase in the serum protein (p<0.001) and albumin (p<0.001) levels of the supplemented women. Haemoglobin was found to be increased in both the groups because of Iron therapy. But the increment was significantly higher (p<0.001) in supplemented group. Thus apart from Iron and Folic Acid, a diet rich in proteins (11 gm) with calories (330 kcal) is essential during pregnancy, at least for a period of 100 days.
Periodic Deworming With Pyrantel For Roundworm And Hookworm Infections In A Farming Village Community.
Guar S.D,Mohapatra S.C
Indian Journal of Community Medicine , 1988,
Abstract: A farming village community of 512 completed one year of periodic deworming with a single 10 mg/kg oral dose of pyrantel every 3 months. Stool examination by Katoa€ s thick smear method showed that the prevalence of roundworm infection (ascariasis) in the community decreased from 76% to 0%, and that of hookworm infection (ancylostomiasis) from 60% to 0%. During the same period the mean hemoglobin increased by 2.3 +/- 0.1 g/dl and the mean body mass index (BMI) increased by 0.90 +/- 0.04(P 0.01 for both) the drug was tolerated very well as side effects occurred following only 6% of doses (130/2048), and only 1% of these required symptomatic treatment. Quarterly deworming with a single dose of pyrantel is an effective and acceptable method of controlling roundworm and hookworm infections in farming village community having a high prevalence of these worms, and it helps improve the general health of the population to significant degree.
A four-neutrino mixing scheme for observed neutrino data
S. C. Gibbons,R. N. Mohapatra,S. Nandi,A. Raychaudhuri
Physics , 1998, DOI: 10.1016/S0370-2693(98)00532-2
Abstract: It has been observed that simultaneous explanation of the solar and atmospheric neutrino deficits and the reported evidence for $\nu_{\mu}\to \nu_{e}$ oscillation from the Los Alamos Liquid Scintillator Detector (LSND) requires at least one extra neutrino species in addition to the three known ones. The extra neutrino must be sterile with respect to the known weak interactions. We present a new mass matrix for these four neutrinos in which the LSND effect and the atmospheric neutrino deficit are governed by only one parameter. We investigate the phenomenological implications of such a mass matrix ansatz and suggest possible ways to understand it in gauge theories.

S. Pattanayak,C. K. Mohapatra,A. K. Mishra
International Journal of Mathematics and Mathematical Sciences , 1987, DOI: 10.1155/s0161171287000553
Abstract: A new class of composition operators P :H2(T) ¢ ’H2(T), with :T ¢ ’D ˉ is introduced. Sufficient conditions on for P to be bounded and Hilbert-Schmidt are obtained. Properties of P with (eit)=aeit+be ¢ ’it for different values of the parameters a and b have been investigated. This paper concludes with a discussion on the compactness of P .
Coherent optical detection of highly excited Rydberg states using electromagnetically induced transparency
A. K. Mohapatra,T. R. Jackson,C. S. Adams
Physics , 2006, DOI: 10.1103/PhysRevLett.98.113003
Abstract: We observe electromagnetically induced transparency (EIT) on the 5s to 5p transition in a room temperature rubidium vapour cell by coupling the 5p state to a Rydberg state (ns or nd with n=26 to 124). We demonstrate that the narrow line-width of the EIT resonance (2 MHz) allows precise measurement of the d state fine structure splitting, and together with the sensitivity of the Rydberg state to electric fields, we are able to detect transient electric fields produced by the dynamics of charges within the cell. Coherent coupling of Rydberg states via EIT could also be used for cross-phase modulation and photon entanglement.
