The Chemical Composition of Post AGB Stars [PDF]

Symposium - International Astronomical Union, 1993
The F-type supergiant HD 56126 (F5I) is an IRAS source with detached cold dust shell with characteristics similar to the dust shells around planetary nebulae. From an analysis of high resolution and high signal to noise ratio spectra metal and CNO abundances have been determined. It is found that in HD 56126 [C/H] =−0.01, [N/H]=+0.17, [O/H] = −0.02, [S/

DNA‐mimic for Specific Surface Functionalization of Zr‐MOFs for Bacterial Targeting

Angewandte Chemie International Edition, EarlyView.
We introduce phosphotyrosine‐modified PNA as a superior, single‐step post‐synthesis surface coating for PCN‐222. The DNA mimic allows for controlled post‐functionalization with single‐stranded DNA for the attachment of protein moieties for bacterial targeting. ABSTRACT Nanosized metal–organic frameworks (MOFs) are versatile platforms used in biomedical

The Circumstellar Envelopes of Post-AGB Stars [PDF]

Proceedings of the International Astronomical Union, 2006
Mid-IR images of a small sample of post-AGB stars have been obtained with the mid-IR camera, OSCIR, mounted on the 8-m Gemini North Telescope. Model calculations, using a 2-D dust RT code, have been performed in order to constrain the physical and chemical properties of the dust in the envelopes, for each object.

What Do We Know About How Companies Manage Waste? The Effect of Tenure and Diversity of Directors on Disclosures

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This paper aims to analyze the effect of board tenure on firms' waste management disclosure and explore whether this effect is amplified by board gender and cultural diversity. The analysis is based on data from 832 large firms worldwide from 2011 to 2020.

Morphological classification of post-AGB stars [PDF]

Proceedings of the International Astronomical Union, 2011
AbstractWe present a complete study of the morphology of post-Asymptotic Giant Branch (post-AGB) stars. The post-AGB stage is a very short evolutionary phase between the end of the AGB and the beginning of the Planetary Nebula (PN) stage (between 100 and 10,000 yrs).

Approaching Gold‐Standard Sensitivity in a Portable and Versatile Gold Nanoprisms Thermoplasmonic Platform for Lateral Flow Detection of Biomolecules

Small, EarlyView.
This study presents a plasmonic thermal lateral flow (ThermoLFA) biosensor for ultrasensitive, early detection of biomolecules. By combining plasmonic gold nanoprisms (AuNPrs) and near‐infrared (NIR) laser activation, it enhances signal output beyond conventional LFAs.

Enterococcus faecalis and Endodontic Treatment Failure: A Qualitative Systematic Review of Its Role and Elimination Strategies

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim of this study was to synthesize evidence on the influence of Enterococcus faecalis on endodontic treatment failure and strategies for its elimination. This study followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and was registered in PROSPERO (CRD420251022741).

CANRIG: Cross‐Attention Neural Face Rigging with Variable Local Control

Computer Graphics Forum, EarlyView.
Abstract Facial animation is one of the most labor‐intensive aspects of animation and VFX, as traditional rigging consumes weeks of expert time and forces animators to spend countless hours manipulating hundreds of controls to achieve varied expressions.

Mid-IR Spectra of AGB and Post-AGB Stars [PDF]

Symposium - International Astronomical Union, 1993
We have generated models of complete nova energy distributions, including the effects of the nova dust shell emission and absorption. In order to account for the dust, we require optical constants throughout the UV and EUV. Draine & Lee (1984) is the only source of such data for silicates.

Passive heat intervention research in women: Systematic review and audit of female representation

Experimental Physiology, EarlyView.
Abstract Passive heat interventions (PHIs) are non‐exercise heat‐acclimation strategies that improve physiological markers associated with heat tolerance and reduce vulnerability to heat‐related illness, when exercise is not feasible. However, representation of female participants within this literature remains unclear.
