Farmers Reap Right to Repair Agricultural Equipment

引用

Engineering 2023年第8期27卷 8-10页

作者： Mitch leslie senior Technology Writer

A farmer is ready to harvest the winter wheat crop when his combine harvester breaks *** if the problem would be relatively simple to remedy,the farmer probably cannot make the repair himself or get help from an independent shop because manufacturers have restricted access to the tools,documentation,and other requirements for fixing their equipment[1].Instead,the farmer will likely have to turn to one of the manufacturer’s dealers,which could mean waiting days or even weeks for a service call from a company technician[2].In the meantime,the farmer’s crop sits unharvested,vulnerable to damage or destruction by bad weather[2].

Commercial Moon Landings Multiply

Engineering 2023年第11期30卷 10-12页

作者： Mitch leslie senior Technology Writer

Along with its familiar impact craters,the surface of the Moon sports numerous pale whorls and streaks known as lunar swirls[1].Likened to the pattern produced when someone pours cream into a cup of black coffee[2],the swirls can extend for more than 50 km and have puzzled researchers for centuries[3].Adding to their mystery,the features are associated with regions of magnetized rocks,an unusual attribute because the Moon lacks a magnetic field[3].Researchers do not know how the swirls are related to the magnetic fields or how they formed.
