Study on the measurment of hoisting mechanism efficiency for bridge crane

Journal of Physics: Conference Series, 2019
Abstract With the bridge crane as a research object, the problem of hoisting mechanism energy consumption and the need of detecting energy consumption are studied by using the black box theory and the serial theory. After the need of measuring reducer power is analyzed emphatically, a plan that measuring simultaneously power of reducer ...

The use of Diathermic Syncope® for stunning cattle

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract The EFSA Panel on Animal Health and Welfare (AHAW) was asked to deliver a scientific opinion on the use of Diathermic Syncope® (DTS) for stunning cattle. A dossier was provided by the applicant as the basis for an assessment of the extent to which the method is able to provide a level of animal welfare at least equivalent to that ensured by ...

Transcriptional Analysis and Genome‐Wide Identification of HA, FRO, and IRT Gene Families Reveal Key Regulators in Pear Seedlings to Short‐Term Iron Deficiency Stress

Food and Energy Security, Volume 15, Issue 1, January/February 2026.
ABSTRACT Iron (Fe) is an essential micronutrient for plant photosynthesis and human health. Pear represents a widely consumed fruit for human Fe intake, yet its yield and quality are frequently challenged by Fe deficiency (FD) stress. Despite the prevalence of FD stress in agricultural production under generally alkaline and calcareous conditions, pear

Design and Implementation of Modular Transmitter Tracks for Dynamic Wireless Power Transfer Systems With Stable Coupling and Outputs

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This study proposes a modular transmitter track design for LCC‐LCC compensated dynamic wireless power transfer systems to mitigate coupling variations during receiver movement. The partially overlapping coils ensure consistent power transfer along different trajectories, with measured current fluctuations below 6.3%.

Efficiency increase in excavation control as primary reserve of performance increase for open-pit excavators

MATEC Web of Conferences, 2018
It is shown that controlling excavation of rock mass using an open-pit excavator with a front shovel as its operational equipment is quite a difficult task due to the complexity of control under almost nonstop adjustment of velocities of working motions (
