Journal of Integrative Plant Biology, EarlyView.The redox‐sensitive transcriptional repressor ZmMS1 coordinates reactive oxygen species homeostasis and lipid allocation for pollen exine and anther cuticle formation. Loss or precocious expression of ZmMS1 causes male sterility. Constitutive overexpression induces dwarfism and semi‐sterility. These findings enable flexible maize male‐sterility systems

A SPOT STRUCTURE OF ACCRETION DISK OF U GEMINORUM
Odessa Astronomical Publications, 2017 On the basis of modelling of emission lines of dwarf novae U Gem, conclusion is made, that the observed orbital phase change of model parameters of a accretion disk can not be explained in frameworks of Keplerian velocity field in a disk.

Radiation from dwarf nova discs
Physics Reports, 1999 We use the Shaviv and Wehrse (1991) code to model the vertical structure and the emission properties of quiescent dwarf nova discs. We find that in the case of HT Cas the quiescent disc must be optically thin, in contradiction with the requirements of the standard disc instability model. We find a viscosity parameter alpha > 1. Although this is much

Hot white dwarfs and the UV delay in dwarf novae [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We calculate the effect of illumination of dwarf nova accretion discs by radiation from a hot, central, white dwarf. We show that only for very hot white dwarfs (Teff ~ 40 000$ K) the inner region of quiescent dwarf nova discs are partially depleted so that the delay between the rise to outburst of the optical and UV fluxes would be increased as ...

The Landless Rural Workers Movement (MST) and New Agrarian Questions in Brazil
Journal of Agrarian Change, EarlyView.ABSTRACT The Landless Rural Workers Movement of Brazil (MST) primarily organized occupations of large‐scale farms, forcing the redistribution of land for creation of agrarian reform settlements. In the past 20 years, however, land occupations and the establishment of new agrarian reform settlements have consistently declined, while the MST shifted ...

The Astrophysical JournalWe present 120 s cadence TESS observations of three superoutbursts of the SU UMa-type dwarf nova VW Hydri. Two events (SO2 in Sectors 87+88 and SO3 in Sector 93) exhibit a temporally pronounced precursor dip followed by a rapid rise into the main ...

Shape of Water: Power Dynamics for Supply Chain Resilience
Journal of Supply Chain Management, EarlyView.ABSTRACT The world is facing climate change‐driven disruptions such as extreme weather events, which affect nature as well as firms and their supply chains. Nonetheless, little is known about how supply chain players shape their socioecological resilience, including from a power perspective.

On the Origin of Episodic Accretion in Dwarf Novae
The Astrophysical Journal, 1998 We show that dwarf nova disks in quiescence have rather low magnetic Reynolds number, of order 10^3. Numerical simulations of magnetized accretion disks suggest that under these conditions magnetohydrodynamic turbulence and the associated angular momentum transport is sharply reduced.

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.Abstract With the growth in the craft brewing industry, farmers are interested in producing winter malting barley (Hordeum vulgare L.). Timely barley planting is important; however, wet weather often results in delays. The objective of this experiment was to identify the agronomic optimum seeding rate (the seeding rate at which yield is maximized) for ...
