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.
Immobilization of Watermelon (Citrullus vulgaris) Urease in Agarose Gel for Urea Estimation
Prakash, Om,Puliga, Srilakshmi,Upadhyay, Lata Sheo Bachan Korean Society for Biotechnology and Bioengineerin 2007 Biotechnology and Bioprocess Engineering Vol.12 No.2
Urease from dehusked seeds of watermelon was immobilized in 1.5% agarose gel with 53.9% entrapment. There was negligible leaching(<10% at $4^{\circ}C$) and the same gel membrane could repeatedly be used for seven days. The immobilization exhibited no apparent change in the optimum pH but there was a significant decrease in the optimum temperature ($50^{\circ}C$ as compared to $65^{\circ}C$ for soluble urease). The immobilized urease revealed an apparent $K_m\;of\;9.3{\pm}0.3 M;$ 1.2 times lower than the soluble enzyme $(11.4{\pm}0.2mM)$. Unlike soluble enzyme which was inhibited at 200mM urea, the immobilized urease was inhibited at 600mM of urea and above, and about 47% activity was retained at 2M urea. The time-dependent thermal inactivation kinetics at 48 and $52^{\circ}C$ was found to be biphasic, in which half of the initial activity was destroyed more rapidly than the remaining half. These gel membranes were also used for estimating the urea content of the blood samples from the University hospital. The results obtained matched well with those obtained by the usual method employed in the clinical pathology laboratory. The significance of these observations is discussed.
MAC Protocols for Opportunistic Spectrum Access in Cognitive Radio Networks
Prakash Prasain,Dong-You Choi 한국정보기술학회 2013 Proceedings of KIIT Conference Vol.2013 No.5
Recently, Cognitive Radio (CR) technology has been proposed as the key technology for future wireless communication that exploits dynamic spectrum access strategies. This offers more flexible way to utilize the wireless spectrum than traditional radio technology based on a fixed spectrum access policy. In cognitive radio networks (CRNs), obtaining the information about spectrum holes on channel, negotiating among primary users and secondary users for spectrum allocation, synchronizing transmission parameters are the important functions of CR medium access control protocols. In this paper, we discuss the basic responsibilities of MAC layer and its functionalities in CRN. Basically, we focus on investigating the recent advances in CR MAC protocols along with their characteristic features, advantages, and drawbacks. At last we provide the major characters of these protocols in tabular form.
