The cooling, mass and radius of the neutron star in EXO 0748-676 in quiescence with XMM-Newton [PDF]

open access: yes, 2017
We analyse four XMM-Newton observations of the neutron-star low-mass X-ray binary EXO 0748$-$676 in quiescence. We fit the spectra with an absorbed neutron-star atmosphere model, without the need for a high-energy (power-law) component; with a 95 per ...

The 2011 October Draconids Outburst. II. Meteoroid Chemical Abundances from Fireball Spectroscopy [PDF]

open access: yes, 2013
On October 8, 2011 the Earth crossed dust trails ejected from comet 21P/Giacobini-Zinner in the late 19th and early 20th Century. This gave rise to an outburst in the activity of the October Draconid meteor shower, and an international team was organized

Spectral changes during dipping in low-mass X-ray binaries due to highly-ionized absorbers [PDF]

open access: yes, 2005
X-ray observations have revealed that many microquasars and low-mass X-ray binaries (LMXBs) exhibit narrow absorption features identified with resonant absorption from Fe XXV and Fe XXVI and other abundant ions.

Assessing Agricultural Green Total Factor Productivity in Latin America

open access: yesAgribusiness, EarlyView.
ABSTRACT The agricultural sector in Latin America plays a vital role in ensuring food security while impacting the environment. However, there remains a lack of analysis regarding the inputs responsible for pollution within its sub‐technologies. Hence, this article aims to assess agricultural green total factor productivity (TFP) through a novel ...

Environmental Sustainability in Wineries: How Contingency Factors and Environmental Management Accounting Tools Influence Environmental Performance?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT How do wineries design sustainability practices and use environmental management accounting (EMA)? This study addresses that question by analyzing the influence of contingency factors on the adoption of sustainability practices and the use of EMA tools to improve the environmental performance of wineries. The research was carried out through a

Influência da incorporação de coberturas mortas e da mobilização no comportamento térmico da camada de ar acima de um Solo mediterrâneo pardo [PDF]

open access: yes, 2010
A aplicação de coberturas mortas (mulches) à superfície do solo ou a simples mobilização deste influenciam directamente o respectivo balanço energético, modificando deste modo o ambiente térmico da camada superficial do solo e o da camada de ar ...

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

open access: yesCytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Making Two out of One: Kinesin Motors Driving Plant Cell Division

open access: yesCytoskeleton, EarlyView.
ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...
