Gravitational Analysis of Einstein-Non-Linear-Maxwell-Yukawa Black Hole under the Effect of Newman-Janis Algorithm

In this paper, we analyze the rotating Einstein-non-linear-Maxwell-Yukawa black hole solution by Janis-Newman algorithmic rule and complex calculations. We investigate the basic properties (i.e., Hawking radiation) for the corresponding black hole solution. From the horizon structure of the black hole, we discuss the graphical behavior of Hawking temperature $T_H$ and analyze the effects of spin parameter (appears due to Newman-Janis approach) on the $T_H$ of black hole. Furthermore, we investigate the corrected temperature for rotating Einstein-non-linear-Maxwell-Yukawa black hole by using the vector particles tunneling strategy which is based on Hamilton-Jacobi method. We additionally study the graphical explanation of corrected $T_H$ through outer horizon to investigate the physical and stable conditions of black hole. Finally, we compute the corrected entropy and check that the effect of charged, rotation and gravity on entropy.Comment: 12 Pages, 8 figures, Published in Physica Script

Design and analysis of a hybrid power system for an offshore aquaculture site in Newfoundland, Canada

The offshore aquaculture industry in Canada is bound to rely on non-renewable energy sources i.e. Diesel Generators (DGs) to meet its intensive energy needs due to absence of utility’s electrical infrastructure. The said energy source is expensive, detrimental for the marine ecosystem, difficult to manage its transport and storage at site. This thesis presents a comprehensive solution to replace the high-cost energy source with a cost-effective and environmentally friendly energy source for an offshore aquaculture site located near Red Island, Newfoundland, Canada. The first step involves inputting the actual energy requirements of the site into Homer Pro software to design a hybrid power system, primarily featuring a floating solar power system (FSPV) to replace DGs. The techno-commercial viability of the designed system is assessed in three scenarios (Base, Ideal, and Worst), all of which show convincing and encouraging levels of renewable energy penetration. By comparing the cost of electrcity calculated by the software with the existing setup's energy cost, it is evident that the FSPV system is economically advantageous in all computed scenerios, base case of the designed FSPV system is 42% cost-effective. To validate the design, the system is modeled in MATLAB, and its dynamic performance is analyzed under varying conditions such as irradiance, temperature, and load side variations. The simulation results demonstrate the system's satisfactory and reliable response in all scenarios. For remote monitoring, a low-cost and open-source LoRA-based SCADA system is implemented. Additionally, an interactive Graphical User Interface (GUI) is developed to visualize historical and real-time data, showcasing the system's performance. The assembled hardware and results affirm that the proposed design is capable of providing a remote monitoring solution for offshore aquaculture sites. The findings underscore the potential of FSPV systems as a viable and sustainable solution for powering fish farms, thereby contributing to the overall sustainability of the aquaculture industry

Service Innovation and Service Innovation Performance: A Study of Banking Services

This study empirically examines the relationship between service innovation and service innovation performance. Typology of service innovation (SI) based on new service offering/product (NSO), new service process (NSP) and new service business model (NSBM)is tested for their likely effect on service innovation performance (SIP) of banks from a developing country context in the face of business environment (BE) characterized by dynamism and competitiveness. It uses quantitative data gathered through cross-sectional self-administered survey questionnaire on a 5 -point Likert-type scale from a sample of 220 managers from the banking organizations to predict the impact of service innovation on service innovation performance. Data are analyzed through SPSS-19 and Amos-18 by means of bivariate correlation and regression. Results indicate a strong impact of multi-dimensional service innovation on service innovation performance. Each dimension of service innovation significantly predicts service innovation performance. Business environment theorized in terms of competition and uncertainty fails to moderate the relationship between service innovation and service innovation performance. In this way, this study offers many valuable insights in the field of service innovation and performance management areas which can be valuable to several stakeholders such as researchers, practitioners and policy makers in developing and implementing optimum service innovation strategies to augment and synergize performance of their services

Bioinspired Nanocomposites: Functional Materials for Sustainable Greener Technologies

This chapter presents a broad overview of the current advancements in bioplastics and bioinspired nanocomposites with nanoscale reinforcements that are being applied for a broad range of applications, that is, biomedical, electronics, durable goods and packaging materials. The production of nanocomposites by completely and/or partially renewable and biodegradable materials has helped in a range of different applications. Several drawbacks of conventional materials such as hydrophilicity, low-heat deflection, poor conductivity, and barrier properties can be efficiently overcome using biohybrid nanomaterials. Nano-reinforcements in composite materials deliver remarkably improved properties such as decrease in hydrophilicity and increase in mechanical properties as compared with neat biopolymer, which fails to exhibit these properties on its own. This approach can be used for other natural polymers to induce desired functionalities. This chapter covers the recent trends in nano-functional materials, renewable materials that are being applied for the production of nanobiocomposites and their applications especially in biomedical and healthcare sectors, which are discussed in detail. This emerging concept will definitely enhance the scope of nanohybrid materials for sustainable products development with improved properties than previously applied synthetic polymer-based or natural polymer-based materials

Stability Analysis of Charged Rotating Black Ring

We study the electromagnetic field equation along with the WKB approximation. The boson tunneling phenomenon from charged rotating black ring(CRBR) is analyzed. It is examined that reserve radiation consistent with CRBR can be computed in general by neglecting back reaction and self-gravitational of the radiated boson particle. The calculated temperature depends upon quantum gravity and CRBR geometry. We also examine the corrected tunneling rate/probability of boson particles by assuming charge as well as energy conservation laws and the quantum gravity. Furthermore, we study the graphical behavior of the temperature and check the stability and instability of CRBR.Comment: 7 pages, 2 figures, version accepted for publication in Symmetr

Flow Injection Photosensitized Chemiluminescence of Luminol with Cu(II)-Rose Bengal: Mechanistic Approach and Vitamin A and C Determination

Rose Bengal photosensitized flow injection chemiluminescence method is reported using luminol-Cu(II) for the determination of vitamins A and C in pharmaceutical formulations. The reaction is based on the enhancement effect of analyte in the production of anion radicals of Rose Bengal (RB•−) which rapidly interact with dissolved oxygen and generate superoxide anions radicals (O2•−) and hydrogen peroxide (H2O2). Highly reactive hydroxyl radicals (•OH) were produced via dismutation of H2O2 by catalyst (Cu2+). The generated superoxide anions radicals and hydroxyl radicals thus oxidize luminol in alkaline medium to generate strong chemiluminescence. The limit of detection (3s of the blank, n=6) of vitamins A and C and RB was found to be 0.008, 0.005, and 0.05 μg mL−1, respectively. The sample throughput of 70 h−1 for vitamins A and C and 30 h−1 for RB was found. Calibration curve was linear in the range of 0.05–15, 0.01–20, and 0.1–50 μg mL−1 for vitamins A and C and RB, respectively, with relative standard deviations (RSDs; n=3) in the range 1.6–3.6%. The method was successfully applied to pharmaceutical formulations and the results obtained were in good agreement with the labeled values

The Potential Impact of Climate Extremes on Cotton and Wheat Crops in Southern Punjab, Pakistan

The assessment of climate extremes’ impact on crop yield is essential to improve our understanding of agricultural resilience. In the present study, we analyzed the potential impact of climate extremes on wheat and cotton production in Southern Punjab, Pakistan using 30-year observed data from the Pakistan Meteorological Department (PMD) and the fifth-generation reanalysis data (ERA-5) from the European Center for Medium-Range Weather Forecasts (ECMWF). Cotton is a Kharif season crop that is sown in May and harvested in October, and wheat is a Rabi season crop that is planted in November and harvested in April. The agricultural data (1985–2015) that contained the crop area and crop yield were obtained from the Bureau of Statistics, Punjab for six selected districts in Southern Punjab. Three precipitation indices, namely consecutive dry days (CDD), consecutive wet days (CWD) and total precipitation of wet days (PRCPTOT), and four temperature indices, namely warm days (TX90p), warm nights (TN90p), cool days (TX10p) and cool nights (TN10p), were selected to analyze the potential impacts of climate extremes on crop production. (1) We found a potential association of TX10p, TN10p, TX90p and TN90p with crop yield in those years for which the production area remained the same. (2) In a few districts of the study area, the wheat yield losses in the Rabi season were associated with an increase in warmer days and warmer nights. (3) The grain size was suppressed due to an increase in the frequency of TX90p and TN90p, which ultimately reduced the net crop production. (4) In some districts, we found strong positive correlations between extreme temperature indices and crop yield; however, other potential factors such as the use of advanced technology, fertilizer, seeds, etc., may lead to improved net production. This study can help in adaptation planning for resilient agricultural production under the stress of climate extreme events in Southern Punjab

Optimiranje podloge za pojačanu proizvodnju glukoamilaze fermentacijom na krutoj podlozi s pomoću gljive Fusarium solani

Solid-state cultivation of Fusarium solani was carried out for enhanced production of glucoamylase (GA) using different substrates like wheat bran, rice bran, green gram bran, black gram bran and maize bran. The SSF medium containing wheat bran as a substrate yielded the highest enzyme activity. The physical and chemical parameters were optimized. Maximum enzyme activity (61.35±3.69) U/g of dry wheat bran was achieved under optimum growth conditions. The optimum conditions were fructose as carbon and energy additive 1 % (by mass), urea as nitrogen additive 1 % (by mass), initial moisture content of solid substrate 70 % (by mass per volume), incubation period 96 h, inoculum size 15 % (by mass per volume) having 10^6–10^7 spores/mL, incubation temperature (35±1) °C and pH=5.0. It was further observed that the addition of surfactants caused a decrease in enzyme biosynthesis by F. solani in SSF of wheat bran under optimum process conditions.Uzgojem gljive Fusarium solani fermentacijom na krutoj podlozi povećana je proizvodnja glukoamilaze (GA) primjenom različitih supstrata kao što su pšenične i rižine posije, te posije zelene soje, crne soje i kukuruza. Najveća aktivnost enzima dobivena je uporabom podloge od pšeničnih posija. Optimirani su fizikalni i kemijski parametri i pri optimalnim uvjetima rasta postignuta je maksimalna aktivnost enzima od (61,35±3,69) U/g suhih pšeničnih posija. Optimalni uvjeti bili su: 1 % (m/V) fruktoze kao izvora ugljika i energije, 1 % (m/m) uree kao izvora dušika, 70 % (m/V) početnog udjela vlage u krutoj podlozi, vrijeme inkubacije u trajanju od 96 h, 15 % inokuluma (m/V) s 10^6-10^7 spora/mL, temperatura inkubacije (35±1) °C i pH=5,0. Dodatkom površinski aktivnih tvari smanjila se biosinteza enzima proizvedenog fermentacijom pri optimalnim uvjetima na podlozi od pšeničnih posija s pomoću gljive F. solani
