An optimized core frame disassembly transportation technology is proposed in response to the transportation challenges of large transformers in remote areas with unique geographical environments or restricted transportation conditions. Through in-depth analysis of key processes such as on-site assembly transformer schemes, disassembly, transportation, and on-site assembly, practical transportation solutions are provided for power generation and planning in remote area energy systems.

Aiming at the problems of a large volume of current electrical five-parameter standard source devices, inconvenience in carrying them to the test site, and difficulty in conducting automatic metrology tests, a PXI board-type electrical five-parameter calibration source device is designed. Together with the driver control and automatic test software, workers can complete the on-site automated verification and calibration of electrical parameter test equipment in automatic test systems and related equipment tests by using the on-site PXI chassis, without the need to carry chassis and desktop devices or disassemble the devices to be tested, which greatly improves work efficiency and realizes portable, channel-expandable, and integrated automatic calibration.

[...]cloud cover was recorded subjectively using a rating scale of 0-night to 4-clear sky. An analysis of covariance (ANCOVA) was conducted with dependent variables air temperature (Ta), relative humidity (Rh), wet bulb temperature (Tw) and two independent variables: field (factor) and surface temperature (Ts) (covariate), including an interaction between field and surface temperature. There was a significant effect of cloud cover, solar radiation, and air temperature on surface temperature on all surfaces.

Introduction: Endoscopic ultrasound guided fine needle biopsy (EUS-FNB) is increasingly utilized to enhance cytological yield of sampling solid lesions under EUS. The impact of a \"FNB-only\" approach in sampling all solid lesions on procedural outcomes has not been reported. Methods: Consecutive patients with solid lesions referred for EUS guided sampling were included. Procedure related outcomes were collected prospectively including patient demographics, procedure duration (from initiation to termination of sedation), sedative doses used, number of passes performed, diagnostic sample adequacy, complications (including post-procedure hospitalizations and emergency department visits) and recovery time. The Acquire FNB needle (Boston Scientific, Natick, MA) was used to sample all lesions in the study group. Tissue was processed on-site with touch or crush preps, with all excess visible cores placed in a cellular preservative for cell block. Additional passes were allocated to cellblock based on the results of the rapid on-site evaluation (ROSE). Consecutive EUS-FNA procedures recently performed to sample solid lesions using the Expect needle (Boston Scientific, Natick, MA) were utilized as controls, and the same procedure related outcomes were abstracted from our clinical databases. Results: 180 patients underwent EUS-FNB and comprised the FNB intervention group. This was compared to 183 recent FNA procedures for solid lesion sampling. There was no difference in age, gender, antibiotic use, or ASA class between the 2 groups. The number of passes was significantly lower in patients who had EUS-FNB compared to EUS-FNA (2.9 vs 3.8, p<0.001). Also, the number of samples obtained as an adequate diagnostic specimen was significantly higher in the patients who underwent EUS-FNB compared to EUS-FNA (177 vs 165, p=0.003) There was no significant difference in the Propofol dose used, recovery time, or rate of complications between both groups. Conclusion: An FNB-exclusive approach to sampling solid lesions under EUS is feasible and may result in fewer overall passes and increased diagnostic adequacy and may obviate the need for on-site pathology review given the high diagnostic yield. FNB may replace FNA as the primary sampling modality of choice in all solid lesions.

Summary Plant diseases caused by viruses limit crop production and quality, resulting in significant losses. However, options for managing viruses are limited; for example, as systemic obligate parasites, they cannot be killed by chemicals. Sensitive, robust, affordable diagnostic assays are needed to detect the presence of viruses in plant materials such as seeds, vegetative parts, insect vectors, or alternative hosts and then prevent or limit their introduction into the field by destroying infected plant materials or controlling insect hosts. Diagnostics based on biological and physical properties are not very sensitive and are time‐consuming, but assays based on viral proteins and nucleic acids are more specific, sensitive, and rapid. However, most such assays require laboratories with sophisticated equipment and technical skills. By contrast, isothermal‐based assays such as loop‐mediated isothermal amplification (LAMP) and recombinase polymerase amplification (RPA) are simple, easy to perform, reliable, specific, and rapid and do not require specialized equipment or skills. Isothermal amplification assays can be performed using lateral flow devices, making them suitable for onsite detection or testing in the field. To overcome non‐specific amplification and cross‐contamination issues, isothermal amplification assays can be coupled with CRISPR/Cas technology. Indeed, the collateral activity associated with some CRISPR/Cas systems has been successfully harnessed for visual detection of plant viruses. Here, we briefly describe traditional methods for detecting viruses and then examine the various isothermal assays that are being harnessed to detect viruses.
