“…The aim of this study was to evaluate how soil vertical cutting with minimum soil disturbance and mowing affect the growth and competitive ability of E. repens in a grass–clover crop. A tractor-drawn prototype with vertical disks was used to fragment E. repens rhizomes with minimal soil and crop disturbance. …”

“…A 4-year-old male presented to our institution in January 2012 after having been run over by a tractor. He presented with gross hemodynamical instability, MISS of 25, and an unstable lateral compression type III pelvic fracture with complete anterior dislocation of the left hemipelvis and a groin wound extending into the left thigh. …”

“…METHODS: Two soils were amended with Chia (Salvia hispanica) seed exudate at 5 concentrations, compacted in cores to 200 kPa stress (equivalent to tractor stress), equilibrated to −50 kPa matric potential, and then compacted to 600 kPa (equivalent to axial root stress) followed by 3 cycles of wetting and drying and recompression to 600 kPa at −50 kPa matric potential. …”

“…Partial least square regression (PLSR) was used to predict V(cmax) (R(2) = 0.83), V(pmax) (R(2) = 0.93), J(max) (R(2) = 0.76), SLN (R(2) = 0.82), and LMA (R(2) = 0.68) from tractor-based hyperspectral sensing. Further assessments of the capability of the PLSR models for V(cmax), V(pmax), J(max), SLN, and LMA were conducted by extrapolating these models to two trials of genome-wide association studies adjacent to the training sets in 2019 (n = 875 plots including 650 genotypes) and 2020 (n = 912 plots with 634 genotypes). …”

“…Our descriptive study involved collecting patient records from the medical clinic during the first 8 months of 2021 (i.e., 1 January–31 August 2021), during which 3050 visits from 1301 port workers were registered. Terminal tractor drivers, crane operators, and stevedores were the most frequent job categories among the patients. …”

“…For sound treatments, we used several types of music, as well as a mix of urban sounds (e.g., sirens, vehicles, and construction equipment), each at volumes comparable to a busy city street or farm tractor. In 18‐hr feeding trials, rock music and urban sounds caused lady beetles to consume fewer aphids, but other types of music had no effect even at the same volume. …”

“…It was only thanks to the remarkable local organizing committee, in particular Carolina Ingvander and Karolin Lundberg, and their persuasive action that we could unload the lorry with the help of a local farmer armed with a tractor normally used for hay-ball transport. Among the visits in the local area, the most remarkable was the one at MAX IV, a brand-new synchrotron radiation facility that adopted innovative solutions for the vacuum system of the 3-GeV storage ring. …”
