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]
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

Thermodynamic structure of the convective boundary layer (CBL) over the Indian monsoon region during CAIPEEX campaigns [PDF]
Spatial and temporal variability in the convective boundary layer (CBL) height for the Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX) study period are examined using the data collected from high-resolution radiosondes ...

Apical ballooning without apical ballooning [PDF]
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.

A “Floatilla” of Airborne Seismometers for Venus
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 ...

Percutaneous transluminal renal angioplasty application effect on renal function in patients with renal artery stenosis: A case report on 4 patients [PDF]
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%.

Valsalva maneuvers have the potential to cause dermal capillary rupture manifesting as purpura and petechiae. We present a unique case of Valsalva purpura occurring in a 12-year-old girl after blowing up multiple balloons at a birthday party.
