Dunaliella salina is a favourable source of high lipid feedstock for biofuel and medicinal chemicals. Low biomass output from microalgae is a significant barrier to industrial-scale commercialisation. The current study aimed to determine how photosynthetic efficiency, carbon fixation, macromolecular synthesis, accumulation of neutral lipids, and antioxidative defence (ROS scavenging enzyme activities) of D.

Article Synopsis
  • Selenium is an essential nutrient for living organisms, but it can be toxic in high concentrations; this study investigated its effects on the growth and accumulation in Dunaliella salina cells.
  • The optimal selenium concentration for growth was found to be 50 mg/L, where the cells demonstrated normal growth and accumulated a moderate amount of selenium, while higher concentrations led to photosynthetic stress and damage.
  • The study suggests that the selenium-enriched biomass from the 50 mg/L exposure could be used for bio-fortifying food and feed due to its health benefits.

In this study, the applicability of physics informed neural networks using wavelets as an activation function is discussed to solve non-linear differential equations. One of the prominent equations arising in fluid dynamics namely Blasius viscous flow problem is solved. A linear coupled differential equation, a non-linear coupled differential equation, and partial differential equations are also solved in order to demonstrate the method's versatility.

This work suggests a method to identify personality traits regarding the targeted film clips in real-time. Such film clips elicit feelings in people while capturing their brain impulses using the electroencephalogram (EEG) devices and examining personality traits. The Myers-Briggs Type Indicator (MBTI) paradigm for determining personality is employed in this study.
