A New Distance to the Supernova Remnant DA 530 Based on HI Absorption of Polarized Emission [PDF]

open access: yes, 2022
Supernova remnants (SNRs) are significant contributors of matter and energy to the interstellar medium. Understanding the impact and the mechanism of this contribution requires knowledge of the physical size, energy, and expansion rate of individual SNRs, which can only come if reliable distances can be obtained. We aim to determine the distance to the

MON-530 Hypoparathyroidism in Sweden

open access: yesJournal of the Endocrine Society, 2019
Introduction: Hypoparathyroidism (HP) is a rare disorder. It is characterized by low serum calcium and inappropriately low parathyroid hormone (PTH) levels. Patients with HP suffer from renal, vascular and neural complications but knowledge about the extent and prevalence of these are sparse.

Energy and Power Considerations in Injection and Optically Pumped Lasers [PDF]

open access: yes, 1963
The topics of power and energy output from lasers are treated. Both three- and four-level lasers are considered in the pulsed and continuous modes of operation. The theoretical power and energy estimates are compared, when possible, with experimental

Protonation Equilibria of L-Aspartic, Citric and Succinic Acids in Anionic Micellar Media

open access: yesE-Journal of Chemistry, 2009
The impact of sodium lauryl sulphate (SLS) on the protonation equilibria of L-aspartic acid, citric acid and succinic acid has been studied in various concentrations (0.5-2.5% w/v) of SLS solution maintaining an ionic strength of 0.16 mol dm-3 at 303 K ...

Production of pizero and eta mesons at large transverse momenta in pp and pBe interactions at 530 and 800 GeV/c [PDF]

open access: yesPhys.Rev.D68:052001,2003, 2002
We present results on the production of high transverse momentum pizero and eta mesons in pp and pBe interactions at 530 and 800 GeV/c. The data span the kinematic ranges: 1 < p_T < 10 GeV/c in transverse momentum and 1.5 units in rapidity. The inclusive pizero cross sections are compared with next-to-leading order QCD calculations and to expectations ...

HF Doppler radar observations of sporadic E at an Indian low latitude station, Visakhapatnam [PDF]

open access: yesAnnales Geophysicae, 2009
5.5 MHz HF Doppler radar observations of Sporadic E over an Indian low latitude station, Visakhapatnam (17.7° N, 83.3° E and Dip 20°) with 10 s resolution showed quasi-periodic variations of the echo strength and Doppler velocity ...

Highly informative simple sequences repeat (SSR) markers reveal the large genetic diversity of mango (Mangifera indica) germplasm in China

open access: yesThe Indian Journal of Agricultural Sciences, 2023
The genetic diversity of mango (Mangifera indica L.) was determined among 188 mango accessions using 40 SSR markers. A total of 303 alleles were discovered, with a mean value of 7.58 and an average PIC of 0.583, showing that the SSR markers utilized in ...

Detection of the extended $γ$-ray emission around supernova remnant DA 530 with Fermi-LAT [PDF]

open access: yesarXiv, 2023
We report the extended GeV $\gamma$-ray emission around the high Galactic latitude supernova remnant (SNR) DA 530 with the PASS 8 data recorded by the Fermi Large Area Telescope (Fermi-LAT). The $\gamma$-ray spectrum in the energy range of 100 MeV - 1 TeV follows a power law model with an index of 2.23. The much more extended $\gamma$-ray emission than

Solar-type Variables [PDF]

open access: yesAIP Conf.Proc.1170:519-530,2009, 2009
The rich acoustic oscillation spectrum in solar-type variables make these stars particularly interesting for studying fluid-dynamical aspects of the stellar interior. I present a summary of the properties of solar-like oscillations, how they are excited and damped and discuss some of the recent progress in using asteroseismic diagnostic techniques for ...

Taxonomic Diversity of Lianas in Tropical Forests of Northern Eastern Ghats of Andhra Pradesh, India

open access: yesNotulae Scientia Biologicae, 2014
Lianas are important in forest ecosystem and strongly influence the forest dynamics and diversity. Lianas are common in the tropical moist deciduous and rain forests, which are competing with other forest trees. Little information is known on the habitat
