This article presents a five-year performance review of an early streamer emission (ESE) air terminal lightning protection system for a large scale PV power plant in Thailand. The comparison effect of a Franklin lightning protection system and the ESE lightning protection system was analyzed for the PV power plant. The ESE lightning protection system was selected to be implemented in the PV power plant. The capacity of the PV power plant studied was 8 MWp on an area of 150,000 square meters in the Nong Ya Plong district, Phetchaburi province, Western Thailand. A Franklin lightning rod type was also designed to be implemented in this PV power plant. The Franklin lightning rod type comprised 122 pieces but the ESE lightning rod type consisted of only 11 pieces. The conceptual design of the Franklin rod type followed the standard of the Council of Engineers, Thailand, and the ESE lightning rod type followed the NFC17102 standard of France. The estimated cost of installation was a key comparison to select the lightning protection system; the total installation cost of the Franklin lightning rod type was USD 197,363.80 and the ESE lightning rod type was USD 44,338.06. The lightning system was applied to the lightning arrester in the power plant to provide good protection, in which the balance of the pole to the mounting position is required to optimize the system performance. The result of the simulation also showed that the shading effects of the Franklin rod type were greater than the ESE rod type. The installation cost of the Franklin lightning rod type was 4.45 times more expensive than the ESE lightning rod type. Therefore, the ESE lightning protection system was selected to be implemented in the PV power plant. From the recorded data of the five-year performance of the ESE lightning protection system (2016–2020), there were three occurrences of a lightning strike on the PV power plant. The ESE lightning protection system effectively protected and prevented the lightning strike to the PV power plant. This study can help and support with the selection of a lightning system for the protection of large scale PV power plants in the future.

AbstractAssociative plasticity occurs when two stimuli converge on a common neural target. We sought to use the strong convergence between motor and sensory systems in the spinal cord to restore movement after spinal cord injury (SCI). We developed a paired motor cortex and dorsal spinal cord stimulation protocol to target this interaction called spinal cord associative plasticity (SCAP). Subthreshold spinal cord stimulation strongly augments motor cortex evoked potentials at the time they are paired, but only when they arrive synchronously in the spinal cord. We tested the hypothesis that this paired stimulation effect depended on cortical descending motor and spinal cord proprioceptive afferents. Selective inactivation of either of these pathways fully abrogated the paired stimulation effect. We then found that repetitive pairing in awake rats increased spinal excitability for hours after pairing ended. To apply this protocol as therapy, we optimized the parameters to promote strong and long-lasting effects. This effect was just as strong in rats with cervical SCI as in un-injured rats, demonstrating that spared connections after SCI are sufficient to support this plasticity. When 30 minutes of paired stimulation was done over 10 days, the effect of pairing was sustained for weeks. In addition, H-reflex modulation improved, showing decreased hyperreflexia that also persisted for weeks. Importantly, repetitive paired stimulation supported enhanced recovery of forelimb dexterity in rats after SCI with no augmentation of injury-induced neuropathic pain. We conclude that SCAP strengthens sensory-motor connections within the spinal cord, resulting in decreased hyperreflexia and improved forelimb function after SCI.Significance StatementDespite evidence that electrical stimulation of spared nervous system connections can facilitate recovery after SCI, strongly overlapping sensory and motor connections in the spinal cord have not been targeted for therapy. Here we demonstrate a robust paired stimulation paradigm that depends on corticofugal and proprioceptive afferent convergence in the spinal cord. The paradigm, termed SCAP for spinal cord associative plasticity, produced large-scale physiological changes in a preclinical model of cervical SCI. Importantly, SCAP caused lasting improvements in dexterity and decreased hyperreflexia in rats with SCI. Thus, we have determined the neural circuits that drive SCAP and have preclinical evidence for its efficacy to restore function after incomplete cervical SCI, the most common SCI in people.

Abstract Background Enhanced recovery after surgery (ERAS) pathways have considerably improved postoperative outcomes and are in use for various types of surgery. The prospective audit system (EIAS) could be a powerful tool for large-scale outcome research but its database has not been validated yet. Methods Swiss ERAS centers were invited to contribute to the validation of the Swiss chapter for colorectal surgery. A monitoring team performed on-site visits by the use of a standardized checklist. Validation criteria were (I) coverage (No. of operated patients within ERAS protocol; target threshold for validation: ≥ 80%), (II) missing data (8 predefined variables; target ≤ 10%), and (III) accuracy (2 predefined variables, target ≥ 80%). These criteria were assessed by comparing EIAS entries with the medical charts of a random sample of patients per center (range 15–20). Results Out of 18 Swiss ERAS centers, 15 agreed to have onsite monitoring but 13 granted access to the final dataset. ERAS coverage was available in only 7 centers and varied between 76 and 100%. Overall missing data rate was 5.7% and concerned mainly the variables “urinary catheter removal” (16.4%) and “mobilization on day 1” (16%). Accuracy for the length of hospital stay and complications was overall 84.6%. Overall, 5 over 13 centers failed in the validation process for one or several criteria. Conclusion EIAS was validated in most Swiss ERAS centers. Potential patient selection and missing data remain sources of bias in non-validated centers. Therefore, simplified validation of other centers appears to be mandatory before large-scale use of the EIAS dataset.
