The proliferation of cyanobacteria has become a significant water management challenge due to the increasing eutrophication of water supply reservoirs. Cyanobacterial blooms thrive on elevated nutrient concentrations and form extensive green mats, disrupting the local ecosystem. Furthermore, many cyanobacterial species can produce toxins that are lethal to vertebrates called cyanotoxins.

Thus, FB-based thermal imaging systems show great potential in some important applications, such as infrared endoscopy, aircraft infrared warning, and satellite remote sensing. In most applications, FBs are required to have high overall transmittance (OT) and high spatial resolution (), but the fabrication of such high-performance FBs is still a challenge.

Remotely Piloted Aircraft Systems (RPAS) are a rapidly expanding technology that operates within the larger complex aviation system. As a result, protective frameworks and risk controls for supporting safe operation are still developing. Adverse events are occurring, yet it is unclear what systemic factors interact to create them.

Background And Objectives: Access to blood components in pre-hospital bleeding resuscitation is challenging. Dried plasma is a logistically superior alternative, and new products are emerging. Therefore, we aimed to evaluate laboratory and practical differences in three differently produced dried plasma products.

Critical Care, Unidade Local de Saúde de Lisboa Ocidental, Lisbon, PRT.
Purpose: As the population ages, critically ill older adults increasingly face complications and require more healthcare resources during hospitalization. Since post-ICU (intensive care unit) mortality is an important consideration, particularly in elderly populations, this study aims to assess whether advanced age impacts ICU and post-ICU mortality by comparing outcomes between patients aged 81 years and above with those below 81 years.
Methods: This retrospective study analyzed data from 3,821 ICU patients treated at the Unidade Local de Saúde de Lisboa Ocidental between 2015 and 2023.
