Source - sink balance and manipulating sink - source relations of wheat indicate that the yield potential of wheat is sink-limited in high-rainfall zones

open access: yes, 2010
Grain yield depends on the number of grains per unit area (sink) and the availability of assimilates (source) to fill these grains. The aim of the current work was to determine whether wheat yield in the high-rainfall zone of south-western Australia is ...

Direct SMBH Formation Driven by Runaway Stellar Collisions in Globally Unstable Stellar Systems

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The fueling problem addresses the ultimate fate of the reservoirs of gas and stars driven into the deepest gravitational potential wells of galaxies, thus it may contain the Universe's densest concentrations of gas and stars. This raises a key question: does the infalling material collapse directly into a supermassive black hole, or can it ...

Illuminating Long-lived Cycas Cotyledons Reduces Sink Demands on Megagametophytes during Initial Seedling Growth

open access: yesHortScience
Cycas megagametophyte resources are translocated to developing seedlings through the persistent green cotyledons. The source activities of cotyledons and megagametophytes following germination are not adequately understood. The decline in megagametophyte

The impact of growth stimulators and retardants on the utilization of reserve lipids by sunflower seedlings

open access: yesRegulatory Mechanisms in Biosystems, 2017
Using growth stimulators and anti-gibberillin preparations of different chemical compounds, we created different pressures in the coordinate covalent bond systems during germination of sunflower seeds.

More‐than‐gender? Moving beyond gendered expectations of divergent learners in early childhood education

open access: yesBritish Educational Research Journal, EarlyView.
Abstract In this paper, we explore how neurodivergent ways of being in early education are often gendered. The intersectionalities of gender and neurodivergence often lead to fixed expectations that perpetuate binary interpretations, pathologisations, missed diagnoses and a lack of curated support.

Effect of changed source/sink relations on proteolytic activities and on nitrogen mobilization in field-grown wheat (Triticum aestivum L.) [PDF]

open access: yes, 2017
Nitrogen mobilization and the pattern of proteolytic enzymes were investigated in leaves and glumes of field-grown winter wheat (Triticum aestivum L.) during maturation. Source/sink relations were changed by removal of the ear, the flag leaf or the lower

From Stakeholder Pressure to Strategic Advantage: A Framework of Achieving Environment Sustainability Through Pathway of Carbon Neutrality

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Businesses are increasingly striving to reduce their carbon footprint, with carbon offsetting emerging as a viable pathway towards achieving carbon neutrality. Such efforts signify a demonstrated commitment to fostering environmental sustainability and contributing to a more sustainable future.

Journey to Net‐Zero and Investment in Renewable Energy: Evidence From Developed and Developing Countries

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines how geopolitical risk, high‐technology exports and the Paris Agreement shape investment in renewable energy across developed and developing economies. Drawing on structural contingency theory, we conceptualise renewable energy investment as a country‐level response to external contingencies and analyse a global panel of 100

Recovery and Utilization of Low-Grade Waste Heat in the Oil-Refining Industry Using Heat Engines and Heat Pumps: An International Technoeconomic Comparison

open access: yesEnergies, 2020
We assess the technoeconomic feasibility of onsite electricity and steam generation from recovered low-grade thermal energy in oil refineries using organic Rankine cycle (ORC) engines and mechanical vapour compression (MVC) heat pumps in various ...
