This keychron m4 article aims to evaluate the potential application of prefabricated panels in energy retrofit of facades in the Portuguese building stock.The fundamentals of this study were part of Annex 50, which was an international ECBCS IEA project, with the purpose of developing an innovative concept of building renovation for the most repres
Capillary Electrophoretic Analysis of Exhaled Breath Condensate in the Diagnosis of Gastroesophageal Reflux Disease
In this work, capillary electrophoresis with contactless read more conductometric detection (CCD) was used for the analysis of the ionic content of exhaled breath condensate (EBC) to differentiate between healthy individuals and patients with gastroesophageal reflux disease (GERD).The exhaled breath condensate was collected using a miniature sample
Analysis of Doppler frequency shift response mechanism based on OFDM system
OFDM system is widely used in mobile communication because of its high spectral efficiency and strong anti-multipath capability.However, in high dynamic scenarios, the Doppler shift between iphone 14 price texas the transmitter and the receiver destroys the orthogonality between the sub-carriers, resulting the interference between the sub-carriers
