Water stress regularly leads to attenuations not only crop growth and ultimately yield. Barley is the only crop that is showed more tolerant behavior among all the cereal. Existing investigation work carried out under irrigated and low water environment with three replications in the pot-house Department of Botany, Baba Mastnath University using a complete randomized design. Incorporation of drought alters the reproductive stage through shifting the flowering in addition to the time of maturity. Mean genotype of days to heading (92.5) in BH-902, days to anthesis (99.5) in AMBER and days to physiological maturity 131.5 in (DWRB-828) whereas, RD-57 had minimum days to heading (73.3), anthesis (81.7) and physiological maturity (111.7). Average relative water content was varied in genotypes from 50.2% to 78.6% and treatments from 70.0% to 53.2%. The present study showed that all genotypes show significant reduction under stress condition with significant interaction effect between genotypes and treatment.

Nanocomposite consisting of Titanium dioxide (TiO 2 ) and silicon dioxide (SiO 2 ) was prepared by the wet chemical method. and their use in the photocatalytic process has been proposed as an alternative to the conventional TiO 2 catalysts(unique textural and structural properties). The prepared samples then characterized by X-ray diffraction, UV-Vis spectroscopy, Fourier transform infrared spectroscopy. TiO2 nanoparticles acquire complete crystalline anatase phase on thermal treatment of asprepared anatase TiO2 at 450°C. The crystallite size of the as-synthesized samples was calculated by Scherrer's formula. And the nanocomposite used in the textile due to its unique and valuable properties. TiO 2 -SiO 2 nanocomposites makes textile to become anti bacterial and wrinkle resistance . Keywords: Nanocomposites, Binary oxides, characterization, Co-precipitation I.INTRODUCTION Nano crystalline TiO 2 has solicits continuous consideration due to its versatile applications in optical devices, sensors, catalysis and photocatalysis etc. Titania based materials are of great concequence for a wide variety of applications because of the interest in their specific physical and chemical properties. The nanocomposite materials (binary mixed oxides) has been widely prepared by coprecipitation method and recognized as one of the promising research area. The chemical properties of the titanium dioxide, in addition to its morphology, are intimately related to the crystallo graphic structure of the solid(e.g. rutile, anatase,brookite) TiO 2 nanoparticles acquire complete crystalline anatase phase on thermal treatment of as-prepared anatase TiO 2 at 450°C. Anatase-rutile mixed phase and rutile phase are achieved by annealing anatase TiO 2 at 700°C and 950°C respectively. [1,2]. By its nature ,crystal domain of nanometric size can be capture for the anatase peculiar, although crystal transition from anatase to rutile results in a enormous increase in crystal domain size [3], and consequently into an important decrease in accessible specific surface area(SSA).Thus, the physical properties of the rutile form of titania become hardly compatible with a use as catalyst support [4]. The use of the anatase form of titania is then most often reported in academic studies as catalyst support [5][6][7] although that the use o ftitania, either anatase or rutile form, remains limited for high temperature reactions. TiO 2 nanoparticles have large specific surface areas and high catalytic performance in which reactions take place on the TiO 2 surface. However, their effective monetary applications are counteracted by two serious disadvantages. Firstly, ultrafine powders will cluster into larger particles, appear in an adverse issue on catalyst performance. Secondly, the separation and recovery of TiO 2 powders from wastewater are difficult [8]. Thirdly, TiO 2 photocatalysis requires ultraviolet (UV) radiation whose energy exceeds the band gap of 3.2 eV (λ -380 nm) of the anatase crystalline phase, utilizing only a very small fraction of su...

Nanopowder binary oxides consisting of Yttrium oxide (Y2O3) and silicon dioxide (SiO2) was prepared by the chemical co precipitation method. The effect of process variables lattice strain of Y2O3:SiO2 was studied using Cental Composite design. The results revealed that the significant factors affecting lattice strain were concentrations and the rate/speed of addition/mixing of precoursors, value and duration of annealing temperature. The optimal calculated parameters were found to be annealing temperature -300 0 C, drop rate-20d/min, concentration of precursors1-1 (w/v), concentration of precursors2-40 mmol/l, lattice strain Ԑ≈.000121 . The formation of Y2O3:SiO2 was confirmed by Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) studies. The strain values are calculated from W-H plot for annealed samples.

BACKGROUNDEpidural analgesia is the most commonly accepted and used technique for painless labour. Local anaesthetic bupivacaine when combined with low dose of opioid analgesics gives excellent results.The aim of this study is to evaluate and compare the efficacy and safety of epidural fentanyl vs butorphanol for painless labour and effect on newborn (Apgar score).Settings and Design -Randomised double-blind trial. MATERIALS AND METHODS50 parturients were randomly allocated in two groups. Group I: receive epidurally 15 mL bupivacaine 0.0625% + fentanyl 30 mcg and Group II: receive epidurally 15 mL bupivacaine 0.0625% + butorphanol 1 mg. RESULTSThe mean onset of analgesia was faster in Group I, whereas duration of analgesia was longer in Group II. There was no incidence of motor block, high rate of Normal Vaginal Delivery and very low incidence of forceps application or LSCS in both the groups. Somnolence was the main side effect in Group II and other side effects were seen equally in both groups. CONCLUSIONThe addition of low dose of opioids has greatly improved the quality of labour analgesia and at the same time reduced the incidence of instrumental deliveries and LSCS without depressing the neurobehavioral status of the newborn.
