Combating anaemia is a global public health challenge of the developing world. Nutritional anaemia is a serious health problem faced by Indian school children. An investigation was taken up to study the effect of non iron containing Ayurvedic preparation Sootshekhar Rasa (SR) plus Sitopaladi Churna (SC) along with iron and folic acid (IFA) for improving nutritional anaemia among adolescent school going students of Dehradun district in Northern India. The blinded, controlled randomized trial comprised of 820 adolescents anaemic students aged 11 - 18 years. The anaemic students were randomly divided into 4 groups, students of group I (control) received starch, group II, III, and IV students received daily dose of (SR 250 mg + SC 400 mg), IFA and (SR 250 mg + SC 400 mg) + IFA, respectively. All the students received treatment for 90days and were followed up for next 180days. At the end of follow-up (day 270), significant increase of haemoglobin (Hb) level from the base line was recorded in all treatment groups. The maximum gain in Hb concentration was noted in group IV (10.1 ± 0.6 g/L), which was significantly higher than any other group. There were 123 drop-outs; however, no major side effect of treatment was noted in any student. We conclude that daily dose of (SR 250 mg + SC 400 mg) along with IFA can produce sustainable improvement of nutritional anaemia in adolescent students.

Recurrent Acute Pancreatitis/ Chronic Pancreatitis (RAP/ CP) is generally marked by sudden onset of symptoms like severe abdominal pain, vomiting and weight loss that needs emergency hospitalization. Owing to irreversible and progressive nature of the disease and limitations of conventional treatment, many patients look for an alternative solution. Here, we report data of 250 well diagnosed cases of acute recurring/ chronic pancreatitis, enrolled in between January 1997 to August 2016, in our Ayurvedic clinical practice in Northern part of India. Ayurveda is well recognized as an independent medical system parallel to conventional medicines in India and a subject is free to opt for any system of medicine for the prevention and treatment of any ailment. The subjects were treated with a complex herbo-mineral formulation based on the principles of Rasa Shastra in Ayurveda that deals with the therapeutics of processed metals in the prevention and treatment of diseases. They were also prescribed a regulated balanced diet and lifestyle. Significant improvement has been noted in subjects who have completed the treatment.

Studies of the dielectric and ferroelectric properties of PZT: NZF magnetoelectric composites
Chandra Prakash,J.K. Juneja,K.K. Raina,Chandra Prakash 한양대학교 세라믹연구소 2012 Journal of Ceramic Processing Research Vol.13 No.1
Piezoelectric-magnetostrictive (magnetoelectric) composites using piezoelectric lead zirconate titanate (PZT) ceramic and magnetostrictive Ni-Zn ferrite (NZF) with compositional formulae (1-x) PbZr0.65Ti0.35O3-x Ni0.8Zn0.2Fe2O4 with x = 0 to 0.15 in steps of 0.05, were prepared by a conventional solid state route. The presence of individual phases was confirmed using X-ray diffraction. Dielectric properties were studied as a function of temperature and frequency presuming that the interactions between the piezoelectric and magnetostrictive phases may result in various anomalies in the dielectric properties of these composites. To study the ferroelectric properties, P-E hysteresis loops were recorded.

Prakash Chandra,Dixit Ambesh 한국물리학회 2022 Current Applied Physics Vol.41 No.-
Using a low-cost hydrothermal method, we demonstrated the fabrication of phase pure rutile phase high-density vertically aligned TiO2 nanorods-based catalyst-free hydrogen (H2) gas sensor. The synthesized TiO2 nanorods on FTO are decorated with the aluminum interdigitated electrode pattern for electrical measurements. TiO2 nanorods-based hydrogen sensor showed the optimum response of ~53.18% at 150 ppm H2 concentration relative to air at 100 ◦C. The measured response and recovery time of TiO2 nanorods are 85 and 620 s, respectively. The TiO2 nanorods-based H2 gas sensor showed a relatively better response, good reproducibility, and stability at moderate temperatures, i.e., 50 and 100 ◦C. The electrochemical impedance measurements showed a small variation in the surface characteristics of TiO2 nanorods before and after exposing H2 gas. The carrier lifetime at 50 ◦C and 100 ◦C at 150 ppm are 5 μs and 3 μs, respectively. Interestingly, H2 selectivity is also observed against H2S, CO, and NH3 gases, suggesting that high-density vertically aligned TiO2 nanorods can be a good candidate for efficient hydrogen sensing at relatively low temperatures.

Vibrations and thermal stability of functionally graded spherical caps
Prakash, T.,Singh, M.K.,Ganapathi, M. Techno-Press 2006 Structural Engineering and Mechanics, An Int'l Jou Vol.24 No.4
Here, the axisymmetric free flexural vibrations and thermal stability behaviors of functionally graded spherical caps are investigated employing a three-noded axisymmetric curved shell element based on field consistency approach. The formulation is based on first-order shear deformation theory and it includes the in-plane and rotary inertia effects. The material properties are graded in the thickness direction according to the power-law distribution in terms of volume fractions of the constituents of the material. The effective material properties are evaluated using homogenization method. A detailed numerical study is carried out to bring out the effects of shell geometries, power law index of functionally graded material and base radius-to-thickness on the vibrations and buckling characteristics of spherical shells.

Metal–organic macrocycles, metal–organic polyhedra and metal–organic frameworks
Prakash, M. Jaya,Lah, Myoung Soo Royal Society of Chemistry 2009 Chemical communications Vol.2009 No.23
<P>Metal–organic macrocycles (MOMs), metal–organic polyhedra (MOPs) and metal–organic frameworks (MOFs) are metal–organic systems (MOSs) developed from appropriately designed ligands and selected metal ions. Metalladiazamacrocycles, a class of MOMs, are finite 2D MOSs formed from tricationic hexacoordinate metal ions and ditopic bridging ligands, <I>N</I>-acylsalicylhydrazide, containing diaza residues, where the size and shape of the systems have been modulated by controlling the steric repulsions between the ligands. The 2D MOM systems could be expanded to 3D MOP systems by self-assembling <I>C</I><SUB>3</SUB> symmetric components and <I>C</I><SUB>4</SUB> symmetric components to octahedral MOPs. By substituting some replaceable solvent sites of MOMs or MOPs, MOFs based on MOMs or MOPs as SBBs have been constructed, where the properties of the SBBs have been directly transferred to the MOF systems.</P> <P>Graphic Abstract</P><P>By substituting some replaceable solvent sites of MOMs or MOPs, MOFs based on MOMs or MOPs as SBBs have been constructed, where the properties of the SBBs have been directly transferred to the MOF systems. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=b902988e'> </P>
