Fabrication of bio-inorganic metal nanoparticles by low-cost lychee extract for wastewater remediation: a mini-review.

Introduction: This review article gives an overview of the biogenic synthesis of metal nanoparticles (mNPs) while using extract as a reducing and stabilizing agent. The subtropical fruit tree i.e lychee contains phytochemicals such as flavonoids, terpenoids, and polyphenolic compounds which act as reducing agents and convert the metal ions into metal atoms that coagulate to form mNPs.

Does green finance mitigate the effects of climate variability: role of renewable energy investment and infrastructure.

Few researches have inspected the task of green finance in reducing CO emissions, while earlier studies have inspected the influence of economic development on carbon emissions. A green finance development index is built using four indicators to fill in this knowledge gap: green credit, green insurance, green securities, and green investing. Using data spanning the years 2005-2019, a panel quantile regression is applied to investigate the links between green finance, renewable energy, and CO emissions.

spp. Mediate defense response in sugarcane through differential exudation of root phenolics.

spp., a ubiquitous biocontrol agent, protects the plants from phytopathogens by suppressing them directly by reinforcing the plant's intrinsic defense mechanism. Root exudated phenolics play an important role in establishing the rhizobacteria population and cross the host boundaries in beneficial plant-microbe interaction.

Assessing the efficiency and total factor productivity growth of the banking industry: do environmental concerns matters?

This paper investigates the efficiency and total factor productivity (TFP) growth of the Pakistani banking industry and determines the impact of risk and competition on the efficiency and TFP growth. The data envelopment analysis (DEA)-based Malmquist productivity index is used to measure efficiency and TFP growth of the Pakistani banking industry. The generalized method of moments (GMM) model is applied to observe the impact of risk and competition on efficiency and TFP growth.

Trilemma association of energy consumption, carbon emission, and economic growth of BRICS and OECD regions: quantile regression estimation.

Recent research has shown a huge impact of non-renewable energy (NRE) production on environmental health. In this context, this work analyzes the effects of GDP growth and long- and short-term consumption of renewable and non-renewable energy (RE and NRE, respectively) on carbon emission in BRICS and OECD economies. The quantile autoregressive distributed lag (QARDL) model was employed on the panel data from 1980 to 2016.

Impacts of risk and competition on the profitability of banks: Empirical evidence from Pakistan.

The purpose of this paper is to investigate the impact of risk and competition on the profitability of the Pakistani banking industry. Data are retrieved from the annual statements of banks, the Ministry of finance Pakistan and the World Bank covering the period of (2007-2017). Two steps Generalized Method of Moments (GMM) with the collapse command is used as an estimation technique to overcome endogeneity, unobserved heterogeneity and autocorrelation problems.

Bacillus spp., a bio-control agent enhances the activity of antioxidant defense enzymes in rice against Pyricularia oryzae.

Plant growth promoting rhizobacteria (PGPR) are found to control the plant diseases by adopting various mechanisms. Induced systemic resistance (ISR) is an important defensive strategy manifested by plants against numerous pathogens especially infecting at aerial parts. Rhizobacteria elicit ISR by inducing different pathways in plants through production of various metabolites.

Molecular Identification and Genetic Characterization of Strains Causing Pathogenicity on Sunflower and Chickpea.

is the most devastating pathogen which causes charcoal rot and root rot diseases in various economically important crops. Three strains 1156, 1160, and PCMC/F1 were tested for their virulence on sunflower ( L.) and chickpea ( L.
