Physical Review D, 1994 Cosmic balloons, consisting of relativistic particles trapped inside a spherical domain wall, may be created in the early universe. We calculate the balloon mass $M$ as a function of the radius $R$ and the energy density profile, $ (r)$, including the effects of gravity. At the maximum balloon mass $2GM/R\approx 0.52$ for any value of the mass density

Characteristics of aerosols over Hyderabad in southern Peninsular India: synergy in the classification techniques [PDF]
Annales Geophysicae, 2012 The present study focuses on analyzing the seasonal changes in aerosol characteristics using a classification scheme proposed by Gobbi et al. (2007). This scheme is based on the correlation between the Ångström exponent (α) in the 440–870 nm range and

Percutaneous transluminal renal angioplasty application effect on renal function in patients with renal artery stenosis: A case report on 4 patients [PDF]
Vojnosanitetski Pregled, 2013 Introduction. Renal artery stenosis (RAS) is narrowing of one or both renal arteries or their branches. Clinically significant stenosis involves narrowing of the lumen, which is approximately 80%.

A “Floatilla” of Airborne Seismometers for Venus
Geophysical Research Letters, 2023 Barometers floating on high‐altitude balloons in the relatively clement cloud layer on Venus could detect and characterize acoustic waves generated by seismic activity, avoiding the need for high‐temperature electronics required for surface seismology ...

Apical ballooning without apical ballooning [PDF]
European Heart Journal, 2006 A 63-year-old woman presented with a sudden exacerbation of chronic obstructive lung disease and elevated levels of cardiac troponin T (0.5 ng/mL). The electrocardiogram exhibited sinus tachycardia, P-pulmonale, and diffuse T-wave inversion. The echocardiogram displayed markedly impaired left ventricular function.

Laryngoscope Investigative Otolaryngology, 2021 Background More than a decade after its introduction, some rhinologic surgeons have incorporated the technique of balloon sinus dilation (BSD) technology into “hybrid” endoscopic sinus surgery (ESS) procedures. A novel BSD device which can be placed over
