As mining operations extend deeper underground, maintaining operational efficiency becomes increasingly crucial due to longer transit times, elevated stresses, heightened seismic activity, increased energy consumption, greater ventilation demands, and extended transport distances—all of which contribute to rising operating costs. In underground mines, haulage vehicles are routinely employed to move ore from subterranean loading stations to the surface. It's occasionally possible for descending empty cars to stop in a passing lane and wait for moving, heavier vehicles to pass. This is how traffic moves downhill. The number and placement of passing bays affect the haulage productivity of a mine. The operational expenses of the battery LHD and the diesel LHD have been contrasted in terms of gases released, diesel costs, and charging costs. According to our data, using a rechargeable LHD can cut operational costs by 90%. In conclusion, without drastically altering production, switching to battery power is possible. The operation of the diesel and battery LHDs is comparable.

Typical manifestations of coronavirus disease (COVID-19) involve the upper and lower respiratory tract. But as the pandemic surges, we are encountering numerous case reports and series of extrapulmonary presentations of COVID-19 in the outpatient department. Abundant retrospective data have also cited various extrapulmonary complications in the hospitalized COVID-19 patients. This knowledge needs to be condensed and disseminated in order to improve COVID-19 surveillance and to reduce the accidental exposure of healthcare workers. Our review suggests that gastrointestinal tract, cardiovascular system, nervous system, renal system, and manifestations due to hematological abnormalities are common masqueraders to watch out for.How to cite this articleAdukia SA, Ruhatiya RS, Maheshwarappa HM, Manjunath RB, Jain GN.

Stent retrieval system is an established treatment modality in acute ischemic stroke with large vessel occlusion. Here, we describe a complication which occurred during mechanical thrombectomy in three cases where the clot dislodged during retrieval. There was a possibility of the clot getting reinjected into the artery with possible dire consequences.
