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.

<P><B>Abstract</B></P> <P>In the present work, we prepared magnesium ferrite/molybdenum trioxide (MFMO) nanocomposite using mechano chemical mixing method for humidity sensor at room temperature. Enhancement in active sites for water adsorption in the composite due to the presence of MoO<SUB>3</SUB> confirmed from X-ray diffraction (XRD) studies. Change in grain size distribution and increase in intergranular pores in the composite favouring water adsorption confirmed from its scanning electron microscopy (SEM) image. Increased agglomeration of nano sized particles and improved crystallinity of the composite confirmed from Transmission electron microscopy (TEM) studies and selected area electron diffraction (SAED) pattern. The composite showed maximum sensing response of 4902 as against 183 of MF in the range 11%–97% RH. The response and recovery times of the composite were found to be 45 s and 74 s respectively while those of MF 225 s and 364 s respectively. The nanocomposite sample showed stable humidity sensing ability and a low humidity hysteresis. Molybdenum trioxide plays a major role in enhancing the humidity sensing performance of MFMO composite at room temperature. The sensing mechanism discussed on the basis of chemisorptions, physisorption and capillary condensation processes.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Humidity sensing response of magnisium ferrite (MF) and magnesium ferrite-molybdenum trioxide (MFMO) composite presented. </LI> <LI> The MFMO showed maximum sensing response of 4902 as against 183 of MF in the range 11%-97% RH. </LI> <LI> The response and recovery times of the composite were found to be 45 s and 74 s respectively. </LI> <LI> The sensing mechanism MFMO discussed on the basis of chemisorptions, physisorption and capillary condensation processes. </LI> </UL> </P>
