<P>An organo-inorganic photocatalytic nanocomposite material based on conjugated polymer, polyaniline (PANI) with titanium dioxide (TiO2) nanoparticles has been developed by performing in situ chemical oxidative polymerization of aniline with ammonium persulfate (APS) oxidant in the presence of hydrothermally synthesized TiO2 nanoparticles. The structural and morphological properties of TiO2/PANI nanocomposites were analyzed by transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR), respectively. The TEM results of the TiO2/PANI nanocomposites showed that TiO2 nanoparticles of 5-10 nm of sizes are dispersed in the PANI matrix. FT-IR spectra show that the TiO2/PANI nanocomposites are almost identical to the structure of PANI alone. The photocatalytic activities of the nanocomposites were evaluated by the photocatalytic degradation of Rhodamine B (RhB), Methylene Blue (MB) and phenol in the presence of UV-light irradiation. The composite catalysts exhibited higher photocatalytic activity for the degradation of organic pollutants than unmodified TiO2 nanoparticles, which is due to sensitizing effect of PANI.

E-Health allows you to supersede the central patient wireless healthcare system. Wireless Body Sensor Network (WBSN) is the first phase of the e-Health system. In this paper, we aim to understand e-Health architecture and configuration, and attempt to minimize energy consumption and latency in transmission routing protocols during restrictive latency in data delivery of WBSN phase. The goal is to concentrate on polling protocol to improve and optimize the routing time interval and schedule communication to reduce energy utilization. In this research, two types of network models routing protocols are proposed – elemental and clustering. The elemental model improves efficiency by using a polling protocol, and the clustering model is the extension of the elemental model that Destruct Supervised Decision Tree (DSDT) algorithm has been proposed to solve the time interval conflict transmission. The simulation study verifies that the proposed models deliver better performance than the existing BSN protocol for WBSN.

This study was undertaken to investigate the efect of biostimulants such as spermidine (1 mM, 2 mM), indole-3-acetic acid (10–3 M, 10–5 M), brassinolide (1 mg/L, 2 mg/L) and boron (50 mg/L, 100 mg/L) on protecting rice plants from heat-induced damage. Two rice genotypes, Nagina 22 (heat tolerant) and Manu Ratna (heat susceptible), primed with biostimulant solution were germinated, 14-day-old seedlings were further foliar sprayed with respective treatment solutions prior to the induction of heat stress (42 °C, 48 h). Heat stress-induced fatal damages to non-biostimulant-treated rice seedlings, whereas biostimulanttreated ones were protected from heat stress-induced damages, marked by lower levels of malondialdehyde (MDA), H2O2 coupled with increased levels of seedling vigour index (SVI), chlorophyll and proline contents. Results showed that 1 mM spermidine (Spd) and 10–5 M indole-3-acetic acid (IAA)-treated rice seedlings showed increased heat tolerance and were evaluated for its efect at reproductive stage stress in a pot culture study. At the panicle initiation stage, plants were pretreated with 1 mM Spd and 10–5 M IAA followed by the induction of heat stress, keeping it in a temperature-controlled polyhouse (42.1 °C, till the time of harvest). Spd- and IAA-pretreated heat-exposed plants exhibited yield improvement over control by altering physiological, biochemical and molecular mechanisms. Therefore, we conclude from our results that foliar IAA or Spd applications can be regarded as an agronomic strategy for mitigating the adverse efects of heat stress conditions on rice plants.
