Classical Novae – Before and After Outburst [PDF]
International Astronomical Union Colloquium, 1988 Classical nova (CN) and dwarf nova (DN) systems have the same binary components (a low-mass main sequence star and a white dwarf) and the same orbital periods. An important question that therefore arises is: are these systems really different ? (and if so, what is the fundamental difference ?) or, are these the same systems, metamorphosing from one ...

Essential embryology for the Canadian pathologists’ assistant
Anatomical Sciences Education, EarlyView.Abstract Pathologists' assistants (PAs) are pivotal in healthcare, conducting autopsies and examining tissues under a pathologist's guidance. Embryology knowledge is crucial for PAs to accurately assess anomalies and identify pathologies. Yet, it is often overlooked in academic PA training programs.

The Astrophysical JournalRecurrent nova (RN) T Pyxidis (T Pyx) has a complex history of mass accreting onto and ejection from the white dwarf, with a classical nova eruption around 1866 kick-starting an RN-phase with six RN eruptions from 1890–2011. T Pyx is a primary progenitor

Long-Term Photometry of Very Slow Novae
Open Astronomy, 2003 Long-term photographic, photoelectric and recent CCD photometry of the classical nova V723 Cas and symbiotic novae V1329 Cyg, PU Vul, V1016 Cyg and HM Sge were used to find their orbital periods.

Influence of new reaction rates on 18F production in novae [PDF]
, 2000 Gamma-ray emission from classical novae is dominated, during the first hours, by positron annihilation resulting from the beta decay of radioactive nuclei.

, 2002 We detected the second historical outburst of the 1920 nova IM Nor. Accurate astrometry of the outbursting object revealed the true quiescent counterpart having a magnitude of R=17.0 mag and B=18.0 mag.

BMEMat, EarlyView.The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.

The Effects of Changes in Reaction Rates on Simulations of Nova Explosions
, 2007 Classical novae participate in the cycle of Galactic chemical evolution in which grains and metal enriched gas in their ejecta, supplementing those of supernovae, AGB stars, and Wolf-Rayet stars, are a source of heavy elements for the ISM.

Pulmonalis or Pulmonaris? It's Elementarius, My Dear Watson
Clinical Anatomy, EarlyView.ABSTRACT The adjectival suffix ‐alis and its allomorph ‐aris are very common in the anatomical nomenclature; however, rules governing differential usage, such as ‐aris substituting for ‐alis following an ‐l‐, leave many exceptions. Here, we report an empirical study of 985 adjectives with ‐alis and ‐aris suffixes used in Terminologia Anatomica (2nd ed.)
