Compression characteristics of local filling gangue in Steeply Dipping Coal Seam
Energy Exploration & Exploitation, 2022 Coal gangue is widely used as a filling material in coal seam mining. During the gangue filling in steeply dipping coal seam, the loading rate, gangue gradation, and filling speed have an important impact on the deformation and failure of gangue, and ...

Grain Filling Characteristics and Their Relations with Endogenous Hormones in Large- and Small-Grain Mutants of Rice. [PDF]
PLoS ONE, 2016 This study determined if the variation in grain filling parameters between two different spikelet types of rice (Oryza sativa L.) is regulated by the hormonal levels in the grains.

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022 Background Exercise‐induced high heart rate may impair exercise tolerance by reducing diastolic filling time and ventricular filling in heart failure with preserved ejection fraction (HFpEF). Given the importance of chronotropic response, we hypothesized

Motion model and key parameters of overburden strata in longwall filling face [PDF]
E3S Web of Conferences, 2021 When the paste material is filled into the longwall working face of the coal mine, it firstly controls the movement of the overburden strata, thereby limiting the movement of the far field rock layer and reducing the subsidence.

Charge balancing fill rate monitor [PDF]
Proceedings Particle Accelerator Conference, 2002 A fill rate monitor has been developed for the NSLS storage rings to allow machine tuning over a very large dynamic range of beam current. Synchrotron light, focused on a photodiode, produces a signal proportional to the beam current. A charge balancing circuit processes the diode current, creating an output signal proportional to the current injected ...

Factors Associated with Nephrology Fellowship Program Fill Rates [PDF]
Clinical Journal of the American Society of Nephrology, 2020 As roughly 60% of nephrology fellowship training tracks go unfilled each year, the nephrology community continues to search for explanations for this long-term trend ([1][1]). Although numerous reasons are proposed for the shortage of trainees entering the field ([2][2]), there has been no ...
