Conciliar Ecclesiology

Ecclesiological diversity abounds in our Mother Church. So too are the ecclesiologies resplendent in the sixteen documents of Vatican II. These sixteen documents are the communitarian, cumulative, and progressive fruition of the application of ressourcement and aggiornamento, the principles of Nouvelle théologie – labelled as French Theology by Pope Francis. It is this théologie that shaped the intellectual vision which laid the theological foundation for the formulation of the documents. This article makes an academic voyage through the kaleidoscope of compelling and convincing Nouvelle théologie to unearth a Conciliar ecclesiology that acknowledges many emerging ecclesiologies reverberating with new pastoral approaches

Basic Ecclesial Communities: Fertile Ground for Religious & Social Harmony

Religious intolerance and blatant polarization along the lines of caste, colour, and racial differences are on the rise in India, a trend that has been compounded by the explicit religious nationalism of the incumbent ruling party, the Bharatiya Janata Party (BJP). In the face of this rising intolerance and polarization, a substantial number of Indians from different demographics have begun to envision and participate in people-centred initiatives to nurture religious and social harmony. The present article proposes that Basic Ecclesial Communities – a practical, resourceful, and sustainable means of fostering community and religious harmony through interfaith sharing, hospitality, and a welcoming mindset – represent an impactful contribution to this effort

Fuzzy-based estimation of reference flux, reference torque and sector rotation for performance improvement of DTC-IM drive

In this study, the fuzzy-based reference flux estimator (RFE), reference torque estimator (RTE) and sector rotation strategy called fuzzy logic estimator are proposed to direct torque control of induction motor (DTC-IM) drive for performance improvement. The basic DTC-IM drive with conventional RFE, RTE and sector division causes large torque ripple, variable switching frequency and uneven voltage vector contribution in stator flux. The torque and speed responses of the proposed system are investigated with load variations. The simulation results of the proposed DTC-IM drive are compared with the basic DTC-IM drive. The assessment of the proposed system shows improved performance. A hardware is developed using Xilinx Spartan-6XC6SLX45-Field Programmable Gate Array (FPGA) Kit for experimental verification of the results. Moreover, sinusoidal pulse width modulation and space vector pulse width modulation techniques are applied to reduce the torque ripples. The performance of the drive is investigated for various speed ranges. The comparison of the simulated and experimental results proves that the proposed fuzzy-based DTC-IM drive provides better performance than the basic DTC-IM drive

Investigation on the photocatalytic activity of chemically synthesized zirconium doped cadmium selenide nanoparticles for indigo carmine dye degradation under solar light irradiation

A simple chemical methodology has been adopted for the synthesis of zirconium (Zr) doped and un-doped cadmium selenide (CdSe) nanoparticles for the application towards photocatalytic degradation of indigo carmine (IC) dye under solar light irradiation. The as prepared Zr-CdSe (doped) and CdSe (un-doped) nanoparticles were characterized by ultraviolet visible spectroscopy (UV-vis), X-ray diffraction (XRD), Scanning electron microscopy (SEM) coupled with energy dispersive X-ray analysis (EDAX) and Transmission electron microscopy (TEM) studies. The inclusion of Zr ion into the CdSe nanoparticles matrix was confirmed by SEM-EDAX and XRD studies. TEM studies confirm the zirconium ions are uniformly doped over the CdSe surface. The photocatalytic degradation performance of Zr doped and un-doped CdSe nanoparticles were examined for the degradation of IC dye under solar light irradiation. The experimental results showed that the Zr doped CdSe possessed greater photocatalytic activity in comparison to un-doped CdSe. Photodegradation process parameters such as the initial concentration of the dye, as well as the amount of catalyst and time were investigated. The photocatalytic degradation rate was favored by a high concentration of solution in respect to Langmuir–Hinshelwood model

ELECTROCHEMICAL STUDIES OF PARACETAMOL ON POLYANILINE-SILVER NANOSTRUCTURAL THIN FILMS MODIFIED GLASSY CARBON ELECTRODE

Analysis of biomolecule of paracetamol through stripping voltammetric determination procedure on polyaniline-silver thin films modified glassy carbon electrode. The effect of pH was studied at different pH media such as 1.0 to pH 13.0. The voltammetric investigation of paracetamol was carried out from −0.2 V to 1.2 V versus Ag/AgCl using modified glassy carbon (GC) as working electrode. The electroanalytical determination parameters are highly dependent on their configuration and on the dimensions of the working carbon electrode. The cyclic voltammogram exhibited one oxidation and one reduction peak. Peak current dependence on the scan rate is studied by varying the scan rate from 25 to 500 mv/s at concentration 300 ppm. The best limit of detection obtained for paracetamol was 10 ppb and the linear range from 100 to 600 ppb on GCE configuration. The biosensors were successfully applied for the detection of paracetamol in several drug formulations

Simulation of 3-phase matrix converter using space vector modulation

This paper illustrates the simulation of 3-phase matrix converter using Space Vector Modulation (SVM). Variable AC output voltage engendered using matrix converter with bidirectional power switches controlled by appropriate switching pulse. The conventional PWM converter engenders switching common mode voltage across the load system terminals, which cause to common mode current and its leads to bearing failure in load drive. These problems can be rectified using SVM and which minimize the effect on the harmonic fluctuation in AC output voltage and stress on the power switch is reduced using bidirectional switch for proposed 3-phase matrix converter. The simulation results have been presented to validate the proposed system using matlab / simulink

Surfactant-mediated and morphology-controlled nanostructured LiFePO4/carbon composite as a promising cathode material for Li-ion batteries

The synthesis of morphology-controlled carbon-coated nanostructured LiFePO4 (LFP/Carbon) cathode materials by surfactant-assisted hydrothermal method using block copolymers is reported. The resulting nanocrystalline high surface area materials were coated with carbon and designated as LFP/C123 and LFP/C311. All the materials were systematically characterized by various analytical, spectroscopic and imaging techniques. The reverse structure of the surfactant Pluronic® 31R1 (PPO-PEO-PPO) in comparison to Pluronic® P123 (PEO-PPO-PEO) played a vital role in controlling the particle size and morphology which in turn ameliorate the electrochemical performance in terms of reversible specific capacity (163 mAhg 1 and 140 mAhg 1 at 0.1 C for LFP/C311 and LFP/ C123, respectively). In addition, LFP/C311 demonstrated excellent electrochemical performance including lower charge transfer resistance (146.3 Ω) and excellent cycling stability (95% capacity retention at 1 C after 100 cycles) and high rate capability (163.2 mAhg 1 at 0.1 C; 147.1 mAhg 1 at 1 C). The better performance of the former is attributed to LFP nanoparticles (< 50 nm) with a specific spindle-shaped morphology. Further, we have also evaluated the electrode performance with the use of both PVDF and CMC binders employed for the electrode fabrication

Diet composition and feeding habits of yellowfin tuna Thunnus albacares (Bonnaterre, 1788) from the Bay of Bengal

Though yellowfin tuna (Thunnus albacares) is one of the important fishery resources in the Bay of Bengal, knowledge on its ecology, diet composition and feeding habits are limited from this area. In view of that, present study focuses on the diet composition and feeding habits of yellowfin tuna (YFT) hooked during exploratory longline survey conducted in the Indian EEZ of the Bay of Bengal during 2019–2021. A total of 213 specimens in the length range of 42.0 to 171.0 cm fork length (FL) were examined, of which 28.2% were empty while the remaining 71.8% contained at least one prey item. The modified Costello graphical method shows a wide range of prey items, with a few prey species that are dominant and can be found in high densities in the Bay of Bengal. Due to the fact that this apex predator is a generalist feeder, this might be the case. Cluster analysis based on the %IRI (Index of relative importance) identified two size groups. YFT with smaller (120 FL), Cephalopods were the dominant prey items of this group and accounts for 62.0% in %IRI followed by teleostea 31.3% of the diet. Cephalopods (Sthenoteuthis oualaniensis) were the primary food consumed in all the size groups, followed by crustaceans (Charybdis smithii) and Teleost fishes (Cubiceps pauciradiatus). The dietary breadth and the occurrence of empty stomachs were significantly related to size of the yellowfin tuna. With increasing body size, diet breadth gradually increased while the percentage of empty stomachs declined. The yellowfin tuna diet does not vary significantly during the seasons. However, cephalopods were found in 53.5% of the IRI in their diet. Furthermore, there were notable seasonal changes in the percentage of empty stomachs, with the highest percentage observed during the monsoon season (38.3%)
