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.
Association of Floral Bud and Anther Size with Microspore Developmental Stage in Campari Tomato
Prakash Babu Adhikari,Won Hee Kang 한국원예학회 2017 원예과학기술지 Vol.35 No.5
Successful anther/microspore culture largely depends on the use of microspores at appropriate developmental stages at the time of culture, which can be specific for each plant species and genotype. This study was carried out to determine the correlation between morphological characteristics, namely floral bud (FB) length and width and anther length, and specific microspore developmental stages in Campari tomato. FBs ranging from 3.55 mm to 18.38 mm were collected, for which FB diameter and anther length were quantified. Furthermore, the developmental stage of microspores contained within these FBs were observed and recorded. The study revealed a strong positive correlation between each size parameters and the progression of microspore development. Moreover, the strongest correlation was observed between anther length and microspore development, indicating that this parameter was more suitable to predict the microspore developmental stage than the FB size parameters. The study also showed wide and overlapping ranges of FB lengths/diameters and anther lengths for specific microspore developmental stages. Subsequent histological observation revealed that this was the result of microspores at multiple developmental stages within a single anther. Moreover, microspores located in the middle of anthers were at a more advanced developmental stage compared to that of microspores at either anther extremity. The results of this study can be readily applied in the collection of Campari tomato FBs/anthers that harbor microspores at particular developmental stages for anther/microspore culture or for further tissue–specific developmental studies. Also, the technique described here can be applied for similar applications in other plant species and genotypes.
Dynamic instability of functionally graded material plates subjected to aero-thermo-mechanical loads
Prakash, T.,Ganapathi, M. Techno-Press 2005 Structural Engineering and Mechanics, An Int'l Jou Vol.20 No.4
Here, the dynamic instability characteristics of aero-thermo-mechanically stressed functionally graded plates are investigated using finite element procedure. Temperature field is assumed to be a uniform distribution over the plate surface and varied in thickness direction only. Material properties are assumed to be temperature dependent and graded in the thickness direction according to simple power law distribution. For the numerical illustrations, silicon nitride/stainless steel is considered as functionally graded material. The aerodynamic pressure is evaluated based on first-order high Mach number approximation to the linear potential flow theory. The boundaries of the instability region are obtained using the principle of Bolotin's method and are conveniently represented in the non-dimensional excitation frequency-load amplitude plane. The variation dynamic instability width is highlighted considering various parameters such as gradient index, temperature, aerodynamic and mechanical loads, thickness and aspect ratios, and boundary condition.
