High-Altitude Ballooning Student Research with Yeast and Plant Seeds
Published in Gravitational and Space Research
Weather balloon flights provide affordable access to a space-like environment for student research. Typical flights last for 2.0-2.5 hours and reach altitudes of approximately 30 km. Payloads are exposed to intense cosmic and ultraviolet radiation, temperatures below -60° C, and atmospheric pressures of approximately 0.01 atmospheres. We report on ...
Ultrafine Friction Grinding of Lignin for Development of Starch Biocomposite Films
The work demonstrates the utilization of fractionalized lignin from the black liquor of soda pulping for the development of starch-lignin biocomposites. The effect of ultrafine friction grinding on lignin particle size and properties of the biocomposites was investigated. Microscopic analysis and membrane filtration confirmed the reduction of ligni...

Transgenerational Plasticity Causes Differences in UV-Tolerance of Intertidal and Subtidal Populations of the Purple Sea...
Planktonic larvae of marine organisms are increasingly being exposed and required to respond to a changing physical environment. Adult sea urchins occupy both intertidal and subtidal waters and broadcast spawn gametes into the water column to contend with variable physical conditions. To answer how populations of invertebrates residing at different...
Estación de medición de Rayos Ultravioleta energizado por un Sistema Fotovoltaico
Introduction: This article discusses the design and implementation of a UV Radiation Measurement Station, known as “Solmáforo”, and energized by an isolated photovoltaic system and information management via web using the Internet of Things (IoT) concept. The implementation of equipment that registers and shows in different ways the incident radiat...
The Impact of Ultraviolet Radiation on Barrier Function in Human Skin: Molecular Mechanisms and Topical Therapeutics.
Published in Current medicinal chemistry
A competent epidermal barrier is crucial for terrestrial mammals. This barrier must keep in water and prevent entry of noxious stimuli. Most importantly, the epidermis must also be a barrier to ultraviolet radiation (UVR) from the sunlight. Currently, the effects of ultraviolet radiation on epidermal barrier function are poorly understood. However,...
Metodologia para validação de dados coletados por espectrofotômetros Brewer
O Instituto Nacional de Pesquisas Espaciais (INPE) monitora fluxos da Radiação Ultravioleta (R-UV), em solo, desde 1990, através de uma rede de espectrofotômetros Brewer no Brasil, Bolívia, Chile e Antártida. O espectrofotômetro é reconhecido pela Organização Mundial de Meteorologia (OMM) e pelo programa Global Atmosphere Watch (GAW) como padrão pa...
A multi-parametric assessment of decontamination protocols for the subglacial Lake Ellsworth probe.
Published in Journal of microbiological methods
Direct measurement and sampling of pristine environments, such as subglacial lakes, without introducing contaminating microorganisms and biomolecules from the surface, represents a significant engineering and microbiological challenge. In this study, we compare methods for decontamination of titanium grade 5 surfaces, the material extensively used ...
