Corrosion Performance of Embedded Steel Bar in Cl--contaminated Limestone Calcined Clay Cement (LC3) at initial stage of hydration

Limestone Calcined Clay Cement (LC3) presents brilliant properties in binding Cl- so that the embedded steel bars are probably protected in Cl--contaminated condition, which meets the need of sea sand application. However, the corrosion performance of steel bars embedded in LC3 paste with Cl‑ is unclear, especially in early age hydration. Thus, a series of experiments were carried out to evaluate the corrosion performance of steel bars on initial and hardened stages of hydration, including concentration of OH- and Cl- in real pore solution, open circuit potential (OCP) and chemical elements of steel bars. In terms of early age hydration, the OCP of steel bars and ions concentration in pore solution indicated that both specimens embedded in PC and LC3 pastes were at a highly corrosion state, however, elemental results showed that no obvious corrosion happened at this stage. With respect to hardened age hydration, visual corrosion could be seen on PC-embedded steel bars, with more Fe3+ and O2-, in comparison with LC3-embedded one, which was related to the much lower absolute OCP and Cl- concentration in pore solution. Overall, LC3 cement demonstrates protective effect on steel bar in special contaminated-Cl- concentration

Edge-InversionNet: Enabling Efficient Inference of InversionNet on Edge Devices

Seismic full waveform inversion (FWI) is a widely used technique in geophysics for inferring subsurface structures from seismic data. And InversionNet is one of the most successful data-driven machine learning models that is applied to seismic FWI. However, the high computing costs to run InversionNet have made it challenging to be efficiently deployed on edge devices that are usually resource-constrained. Therefore, we propose to employ the structured pruning algorithm to get a lightweight version of InversionNet, which can make an efficient inference on edge devices. And we also made a prototype with Raspberry Pi to run the lightweight InversionNet. Experimental results show that the pruned InversionNet can achieve up to 98.2 % reduction in computing resources with moderate model performance degradation

Memperbaiki Saturasi Oksigen, Frekuensi Denyut Jantung, Dan Pernafasan Neonatus Yang Menggunakan Ventilasi Mekanik Dengan Terapi Musik

Improving Oxygen Saturation, Heart Rate, and Respiratory Rate of Neonates Using Mechanical Ventilation with Music Therapy. Neonates using mechanical ventilation cause of respiratory disorder experience oxygenation and heart rate problems. Interventions should be made in order to calm neonates so that the need of oxygen can be minimized, one of these interventions is music therapy. This study aimed to identify the effect of music therapy on oxygen saturation, heart rate and respiratory rate of neonates using mechanical ventilation. This quasi experiment study with a pretest-posttest design without control involved 13 neonates selected by consecutive sampling. Data collected through observation and analyzed by paired t test. There was a significant difference on the average of oxygen saturation, heart rate and respiratory rate of infants using mechanical ventilation before and after music therapy (p value <0,05). Music therapy can be used as a complementary medical therapies to improve oxygenation in neonates using mechanical ventilation
