JUSTIFICATION OF VALUES FACTOR CONTROLLER VIBRATION DAMPING SHIPPING BRIDGE CRANES

Вестник СибАДИ, 2017
As a result of computational experiments on the simulation model of the bridge crane with controller cancellations load fluctuations when it is moved to test trajectories are obtained depending on the indicators characterizing the process of moving from ...

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Mindfulness and resilience: The experiences of global majority students in a mindfulness intervention Programme at a UK university

British Educational Research Journal, EarlyView.
Abstract Wellbeing in higher education (HE) in the United Kingdom has been increasingly prioritised for many institutions, with a growing demand for student support requests. There are various determinants in life that can influence mental health. As such, protected characteristics, including race, can indicate that students who are Black or Asian ...

METHOD OF THE DRIVE POWER DETERMINATION OF THE MECHANISMS OF THE BRIDGE CRANE MOVEMENT CONSIDERING THE ROLLING FRICTION

Nauka ta progres transportu, 2015
Purpose. The value of drive resistance to its movement is the main parameter at calculating the drive power of bridge crane. The value of the wheel rolling friction on the rails is one of the important parts of the resistance to movement. It is necessary

Magnetic field stabilization for high-accuracy mass measurements on exotic nuclides [PDF]

, 2007
The magnetic-field stability of a mass spectrometer plays a crucial role in precision mass measurements. In the case of mass determination of short-lived nuclides with a Penning trap, major causes of instabilities are temperature fluctuations in the ...

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
