TL;DR: The result shows that proposed technique is capable of right tripping action and classification of type of fault at high speed therefore can be employed in practical application.
Abstract: This study presents fuzzy logic based online fault detection and classification of transmission line using Programmable Automation and Control technology based National Instrument Compact Reconfigurable i/o (CRIO) devices. The LabVIEW software combined with CRIO can perform real time data acquisition of transmission line. When fault occurs in the system current waveforms are distorted due to transients and their pattern changes according to the type of fault in the system. The three phase alternating current, zero sequence and positive sequence current data generated by LabVIEW through CRIO-9067 are processed directly for relaying. The result shows that proposed technique is capable of right tripping action and classification of type of fault at high speed therefore can be employed in practical application.

TL;DR: In this paper, the use of Musa acuminata (banana peel ash) as a heterogeneous catalyst for C-C bond formation via a Henry reaction under solvent-free conditions at ambient temperature was reported.
Abstract: Owing to the depletion of resources coupled with increasing waste generation, the conversion of waste biomass to value-added materials has gained interest. Here, we report for the first time the application of Musa acuminata (banana) peel ash (MAPA) as a heterogeneous catalyst for C–C bond formation via a Henry reaction under solvent-free conditions at ambient temperature. The catalyst was well characterized using different analytical techniques like FT-IR, SEM, TEM-EDS, XRD, XRF, XPS, BET and TGA, along with basicity determination by a Hammett indicator test and titration method. An excellent yield of nitroalcohol was obtained within 15–30 minutes. No dehydrated product was observed. The catalyst used in these studies has the advantage of being a waste material and is hence low-cost, easily prepared, recyclable and environmentally friendly. In addition, the use of a biogenic renewable catalyst, its atom economy, and room temperature and solvent-free reaction conditions and the avoidance of column chromatography make the protocol highly significant from green and sustainable chemistry perspectives.

TL;DR: In this paper, the authors employ an effective Lagrangian approach to study the decay branching fractions and the ratio of branching fractions of the leptonic and semileptonic meson.
Abstract: Deviations from the standard model prediction have been observed in several leptonic and semileptonic $B$ meson decays to $\ensuremath{\tau}\ensuremath{ u}$ final states mediated via $b\ensuremath{\rightarrow}u$ and $b\ensuremath{\rightarrow}c$ charged current interactions. The measured value of the ratio of branching ratios ${R}_{\ensuremath{\pi}}^{l}$ of ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\tau}}^{\ensuremath{-}}{\ensuremath{ u}}_{\ensuremath{\tau}}$ to ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{l}^{\ensuremath{-}}\ensuremath{ u}$ decays, where $l=(e,\ensuremath{\mu})$, is larger than the standard model prediction by more than a factor of 2. Similarly, a combined excess of $3.9\ensuremath{\sigma}$ from the standard model expectation has been reported by HFAG for the values of ${R}_{D}$ and ${R}_{{D}^{*}}$, where ${R}_{D,{D}^{*}}$ represents the ratio of branching ratios of $B\ensuremath{\rightarrow}(D,{D}^{*})\ensuremath{\tau}\ensuremath{ u}$ to corresponding $B\ensuremath{\rightarrow}(D,{D}^{*})l\ensuremath{ u}$ decays, respectively. Very recently, a hint of lepton flavor violation has been observed in the ratio of branching fractions of $B\ensuremath{\rightarrow}K{e}^{+}{e}^{\ensuremath{-}}$ to $B\ensuremath{\rightarrow}K{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ decays as well. In this context, we employ an effective Lagrangian approach to study the decay branching fractions and the ratio of branching fractions of ${\mathrm{\ensuremath{\Lambda}}}_{b}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Lambda}}}_{c}l\ensuremath{ u}$ and ${\mathrm{\ensuremath{\Lambda}}}_{b}\ensuremath{\rightarrow}pl\ensuremath{ u}$ decays within the standard model and beyond. We constrain the new physics parameter space using the existing experimental data on ${R}_{D}$, ${R}_{{D}^{*}}$, and ${R}_{\ensuremath{\pi}}^{l}$. We give predictions for various observables in the context of various new physics scenarios.

TL;DR: In this paper, a biogenic, cost effective and highly efficient activated carbon@SnO2 nanocomposite adsorbent was developed to meet the challenges in the drinking water dearsenification and defluoridation in rural areas.
Abstract: The aim of the research work is to design and develop a biogenic, cost effective and highly efficient activated carbon@SnO2 nanocomposite adsorbent to meet the challenges in the drinking water dearsenification and defluoridation in rural areas. Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), N2 isotherm analysis, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and X-ray Photoelectron Spectroscopy (XPS) were conducted to characterize surface and textural properties of the as-prepared nanocomposite. The adsorption behavior of the nanocomposite towards As (III) and fluorides were carefully explored using adsorption isotherms and kinetic studies. Effects of initial pH, contact time, temperature, ionic strength, presence of interfering ions over percentage removal of arsenic and fluoride and economic feasibility of the adsorbent generation have also been investigated. Under optimum conditions: pH 6, contact time 150–180 min, NaCl conc. 0.001 M, percentage removal for As (100 ppb) and fluoride (10 ppm) solutions were found to be 92–95% and 82–85% respectively. The present adsorption process could reduce the arsenic and fluoride concentration in both synthetic and spiked ground water to below 10 ppb and 1.5 ppm respectively which are the maximum permissible limits according to the World Health Organization (WHO) drinking water guidelines.
