Analyzing soil in large and remote areas such as the Amazon River Basin (ARB) is unviable when it is entirely performed by wet labs using traditional methods due to the scarcity of labs and the significant workforce requirements, increasing costs, time, and waste. Remote sensing, combined with cloud computing, enhances soil analysis by modeling soil from spectral data and overcoming the limitations of traditional methods. We verified the potential of soil spectroscopy in conjunction with cloud-based computing to predict soil organic carbon (SOC) and particle size (sand, silt, and clay) content from the Amazon region.

Article Synopsis
  • This study focuses on creating and testing 6-aminated 1,4-benzoquinones (6-AQs) for their ability to combat seven resistant pathogens.
  • The 6-AQs were synthesized using a reaction between bromoquinone and substituted anilines, and their antimicrobial effectiveness was analyzed, revealing minimum inhibitory concentrations between 16 to 128 μg/ml.
  • Notably, two derivatives showed effectiveness against methicillin-resistant strains, showcasing both bacteriostatic and bactericidal properties and suggesting these compounds as potential new treatments.

Phosphorus (P) is a critical nutrient for primary production in terrestrial and aquatic ecosystems. As P mineral reserves are finite and non-renewable, there is an increasing discussion on its sustainable utilization to safeguard food security for future generations. Understanding the spatial distribution of soil P is central in advancing effective phosphorus management and fostering sustainable agricultural practices.

This study aimed to assess the sonographic features of abdominal organs in healthy captive Neotropical otters (Lontra longicaudis). The sonograph showed that the urinary bladder was located in the caudal abdomen and its content was uniformly anechoic. The bladder wall had three layers: outer hyperechoic serosa, hypoechoic muscular layer and hyperechoic mucosa.
