To mitigate the environmental effects of burning fossil fuels for power generation, clean, self-renewing, and efficient technologies are being developed and used. Photovoltaics have received attention during the last decades to supplement conventional power production systems. Photovoltaic technology has advanced in the eyes of developers, policymakers, and investors due to the consistently falling costs of photovoltaic panels and improving control systems.

Article Synopsis
  • A total of 34 algal species from the class Nostocophyceae and family Oscillatoriaceae were studied using light microscopy (LM) and scanning electron microscopy (SEM) in north-eastern Punjab.
  • The species are distributed across nine genera, including Arthrospira, Lyngbya, Oscillatoria, Spirulina, Phormidium, and Microcoleus, highlighting the area's rich algal diversity.
  • The research emphasizes the importance of using both LM and SEM for accurate identification of algal species, especially when examining their presence in wastewater across different regions and seasons.

Background: Hepatitis C viral (HCV) infection is a major clinical burden globally. Pegylated IFN-α-2a (PEG-IFN-α-2a) with ribavirin (RIB) therapy induces an array of cellular antiviral responses, including dsRNA kinases (PKR), chemokines, and cytokines to tackle the HCV infection. However, many HCV patients develop resistance to PEG-IFN/RIB therapy rendering the therapy ineffective.

Article Synopsis
  • C. perfringens, a bacterium causing enteric infections in poultry, produces various toxins; toxinotype A is particularly prevalent in Pakistan and responsible for necrotic enteritis (NE) in birds.
  • A study isolated 34 strains of C. perfringens from 134 intestinal samples, showing a prevalence rate of 25.37%, all classified as toxinotype A, characterized by the presence of alpha toxin and absence of others.
  • The isolated strains exhibited multidrug resistance, especially to commonly used antibiotics in the poultry industry, indicating a serious threat to poultry health and underscoring the urgent need for new antibiotics and alternative treatments.

The optimal design and performance monitoring of wind farms depend on the precise assessment of spatial and temporal distribution of wind speed. The aim of this research is to investigate the appropriateness of nine popular probability distribution models (exponential, gamma, generalised extreme value, inverse Gaussian, Kumaraswamy, log-logistic, lognormal, Nakagami, and Weibull) for the assessment of wind speed distribution (WSD) at 10 sites situated at topographically distinct locations in Tamil Nadu, India, based on 39 years of data. The results suggest that a single distribution cannot produce best fit for all the stations.

The objective of this work is to understand the fluctuating nature of wind speed characteristics on different time scales and to find the long-term annual trends of wind speed at different locations in South Africa. The hourly average mean wind speed values over a period of 20 years are used to achieve the set objective. Wind speed frequency, directional availability of maximum mean wind speed, total energy, annual energy yield and plant capacity factors are determined for seven locations situated both inland and along the coast of South Africa.

The present study explores a series of novel donor-π-acceptor (D-π-A) molecules containing 4,4'-dimethyldiphenylamine moiety as donor, 4,4'-dinitrodiphenylborane as acceptor while different π-bridges as efficient linkers between them, which comprises of (-HCCH-), (-Ph-) and (-Ph ̶ HCCH-) combinations for compounds in series 1, 2 and 3, respectively. Quantum chemical computations are applied to calculate the linear polarizability (α), first (β) and second (γ) hyperpolarizabilities. A comparative analysis is performed considering an increase of NLO polarizabilities as a function of different π-linkers.

Recent studies have demonstrated a close interaction between neuroinflammatory responses, increased production of inflammatory mediators, and neurodegeneration. Pathological findings in neurological diseases such as Alzheimer's disease, Parkinson's disease, and Huntington's disease have shown common signs of neuroinflammation and neurodegeneration. Lupeol, a natural pentacyclic triterpene, has revealed a number of pharmacological properties including an anti-inflammatory activity.

This study was conducted to investigate the concentrations of heavy metals in soil and vegetables, and human health risks through ingestion of contaminated vegetables. Soil and vegetable samples were collected from different locations in Gilgit, northern Pakistan, and analyzed for Cd, Cu, Ni, Pb and Zn. Plant transfer factors (PTF), daily intake of metals (DIM) and health risk index (HRI) were also calculated.

This study was conducted to investigate the effectiveness of a continuous free surface flow wetland for removal of heavy metals from industrial wastewater, in Gadoon Amazai Industrial Estate (GAIE), Swabi, Pakistan. Industrial wastewater samples were collected from the in-let, out-let and all cells of the constructed wetland (CW) and analyzed for heavy metals such as lead (Pb), cadmium (Cd), iron (Fe), nickel (Ni), chromium (Cr) and copper (Cu) using standard methods. Similarly, samples of aquatic macrophytes and sediments were also analyzed for selected heavy metals.

Background, Aim, And Scope: Soil contamination with heavy metals occurs as a result of both anthropogenic and natural activities. Heavy metals could have long-term hazardous impacts on the health of soil ecosystems and adverse influences on soil biological processes. Soil enzymatic activities are recognized as sensors towards any natural and anthropogenic disturbance occurring in the soil ecosystem.
