REFLECTIONS ON IMAGE AND PHOTOGRAPHY: possibilities in research and teaching of Physical Education
Starting this reflexion from the theoretical contributions such as Guy Debord and Susan Sontag to have a critical understanding of our reality, mediated by images, we intend, throughout this article, to reflect to the reader, some ability to think and ...

Source apportionment resolved by time of day for improved deconvolution of primary source contributions to air pollution [PDF]
Present methodologies for source apportionment assume fixed source profiles. Since meteorology and human activity patterns change seasonally and diurnally, application of source apportionment techniques to shorter rather than longer time periods ...

Optical Birefringence Fiber Temperature Sensors in the Visible Spectrum of Light
This article describes experimental tests to determine PM fibers Panda style responses to a thermal source with different initial temperature. The aim of this study was to determine the sensitivity of a polarization maintaining fiber to the radiating ...

PMF forecasting for count processes
Coherent forecasting techniques account for the discrete nature of count processes. Besides point and interval forecasts, a third way for achieving coherent forecasts is to consider the full predictive probability mass function (PMF) as the actual ...

Accelerating Phosphate Transport Across Membranes via Synergistic Chemical‐Electrochemical Carriers
A new membrane design principle based on synergistic chemical and electrochemical carriers is proposed to construct an electro‐driven carrier‐conducting membrane for high‐throughput phosphate transport. Monodispersed ferrihydrite nanoparticles embedded within the membrane act as built‐in phosphate carriers, enabling accelerated phosphate migration via ...

The Analysis of Fiber Sensor of Temperature Field Disturbance by Human Body Part Access
The principle of this sensor function is based on polarization maintaining fiber (PMF) sensitivity during excitation of both two polarization modes. This excitation is caused by temperature change, when absorbing thermal radiation. This mechanism is used

A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering
