Acute Osmotic and pH Shock to Bioluminescent Bacteria Is Reversible in Terms of Luminescence Response.
Luminescence

Department of Biomedical Science, Acharya Narendra Dev College, University of Delhi, New Delhi, India.
Bioluminescence inhibition (BLI) measurements in bioluminescent bacteria (BB) is perceived as a potential qualitative and quantitative indicator of hazardous materials. Acute but minor fluctuations in osmolarity and pH do not affect the living systems significantly. However, significant BLI is observed from marine BB due to acute osmolarity or pH changes that may affect the bioassay sensitivity.

Solar desalination shows promise in tackling freshwater shortages, but challenges arise from the trade-off between water transportation and heat supply, affecting evaporators' efficiency and salt resistance. Additionally, intermittent nature of solar radiation significantly diminishes overall evaporative performance. This study presents dual-gradient heating solar evaporator for efficient desalination.

Application of hyperspectral reflectance technology to track changes in photosynthetic activity in () remains underexplored. This study aimed to investigate the relationship between hyperspectral reflectance and photosynthetic activity in the leaves of in response to a decrease in soil water content. Results demonstrated that the reflectance in both the visible light and near-infrared bands increased in conjunction with reduced soil water content.

Department of Agriculture, Food and Environment, University of Pisa, 56124 Pisa, Italy.
Sheep in Italy are exposed to heat stress (HS) for several months, increasing the risk of HS-related problems such as the decrease in growth, reproductive performance, milk quantity and quality and natural immunity. This study aimed to assess changes in hematological and biochemical parameters in dairy sheep from three different farms with varying pasture management: A (no water or shade), B (water but no shade), and C (both water and shade). From March to June, when HS risk is high, monthly blood samples (T1-T4) were collected from 20 sheep per farm (total n = 60).
