Summary: The study proposes a Rogowski coil sensor design to measure current flux in the mechanical joints of different fuselage panels. The sensor is analyzed theoretically, modeled in a circuit, and a printed circuit board (PCB) Rogowski coil is designed for measuring high-intensity pulsed currents. The probe's characteristics are evaluated through S-parameters, and its transient response is validated through simulation. The Rogowski coil sensor is then experimentally evaluated in measuring a surge current pulse.

Summary: The electromagnetic characterization of reaction wheels is essential for space science missions to meet the ac magnetic field cleanliness requirements and prevent interference on sensitive instrumentation. This article proposes a complete assessment, including measuring the magnetic flux vector under different operational modes and dynamic conditions, using a test setup based on multichannel acquisition and multidomain postprocessing. The focus of the measurement campaign was on the low-frequency range, and capturing the B-field in the time-domain enabled complementary analysis for understanding the reaction wheel's electromagnetic performance.

Summary: This study aimed to explore the feasibility of using single-step genomic best linear unbiased prediction (ssGBLUP) for genomic prediction of productive and reproductive traits in Guzera cattle. The results showed that ssGBLUP was feasible and could increase the accuracy of breeding values without significantly impacting predictive ability and bias. Although the number of genotyped animals and the size of the database were small for some traits, the individual accuracies of breeding values were evidently increased in the genomic evaluation.

Summary: This study estimated genetic parameters, effective population size, inbreeding, and inbreeding depression in Piau pigs. The results showed low direct heritabilities for birth weight and weaning weight, while average pre-weaning daily weight gain showed moderate heritability. There were high genetic correlations between weight at birth and weight at weaning, as well as weight at weaning and average pre-weaning daily weight gain. Inbreeding increased over generations and led to a reduction in effective population size. Inbreeding had a significant effect on average pre-weaning daily weight gain, with a decrease of 0.005 g for every 1% increase in inbreeding coefficient. Increasing effective population size is necessary to control inbreeding and preserve genetic variability in the Piau pig population.

Summary: This study quantified runs of homozygosity (ROH) and heterozygosity-rich regions (HRR) in a subpopulation of Guzer & aacute; cattle and examined ROH and HRR islands. The results showed that the inbreeding coefficients determined by ROH were higher than other cattle breeds' and higher than pedigree-based inbreeding in the Guzer & aacute; breed obtained in previous studies. Additionally, genes identified in ROH and HRR islands were associated with dairy and beef traits, reproductive traits, and disease resistance.
