Abstract:

Emphysema bullae are often found in patients with chronic obstructive pulmonary disease and if the size of the bulla fulfills > 30% of the hemithorax, it can be called a giant bullae. A giant bullae can be similar to a pneumothorax, requiring a CT scan of the chest to avoid misdiagnosis and unnecessary procedures. The difference between a bulla and a pneumothorax obtained from imaging results is that if the lung collapses towards the ipsilateral hilum it is called a pneumothorax, while the bulla will appear to surround or wrap around the lung. Asthma is a disease characterized by chronic in

We present the case of a 38-year-old man, with congenital bullous emphysema, who presented with unilateral pleuritic chest pain, rigors and a non-productive cough.

There were fluid levels present within several bullae, with the largest bulla compromising most of the posterior aspect of the left lung base. We suspected infected emphysematous bullae.

However, the hemodynamic instability that can occur due to the mass effect of an unruptured giant bulla should not be overlooked.

Abstract The most common cause for primary spontaneous pneumothorax (PTX) is congenital blebs or bullae. All patients with primary spontaneous PTX require high-resolution computed tomography thorax to find the underlying structural lung disease if any, as the cause for PTX. A thorough family history and physical examination are also essential to find the underlying predisposing causes if any. We report a case of primary spontaneous PTX in a young female with localized multiple bullae without any obvious predisposing factors which is unusual.

Our results show that none of the abundance ratios vary significantly with latitude.

Those systems include wide binary radio pulsars, millisecond pulsars (not in wide binaries), galactic bulge X–ray sources (including QPO’s), type I X–ray burst sources and X–ray transients, andγ–ray sources.

Within 8° of the Galactic center (∼ 1 kpc) our data are consistent with no gradient in the distribution of [Fe/H], which may hint to a dissipationless collapse, and/or sufficient mixing during the star-forming epoch when Fe was produced in the bulge.

AbstractThe Galactic bulge is the central spheroid of our Galaxy, containing about one quarter of the total stellar mass of the Milky Way (Mbulge = 1.8 × 1010M⊙; Sofue, Honma & Omodaka 2009). Being older than the disk, it is the first massive component of the Galaxy to have collapsed into stars. Understanding its structure, and the properties of its stellar population, is therefore of great relevance for galaxy formation models.

Early-type spirals (bulge plus disc systems) sprawl across both peaks.

Abstract:

Anesthetic management for patients with a giant emphysematous bulla (GEB) is challenging. This case report describes a patient who developed 95% pulmonary compression by a GEB. A 14-Ga indwelling catheter was placed in the GEB before surgery to allow for slow re-expansion of the collapsed lung tissue. This prevented rupture of the GEB during anesthesia. Additionally, positive-pressure ventilation was performed to reduce the risk of re-expansion pulmonary edema. This respiratory management strategy may be beneficial for patients with a GEB who develop pulmonary dysfunction during thoracic surge

Abstract:

We have performed 2D relativistic hydrodynamic simulations of jets from a collapsar. The light curves and spectrum of the photospheric thermal radiation from ultrarelativistic gamma-ray burst (GRB) jets are calculated by the post process. At the head the jet has a dissipated region in which internal shocks can be seen and a freely expanding region follows. The freely expanding region shows a bullet like shape. The light curves continue about 100 s which corresponds to the jet injection duration. The light curves for θv ≤ 2° show quick rise and time variability for the first phase and low and s

In the section of the eastern Black Sea basin and the Caucasus continental slope, according to 3D seismic data, unique objects were first discovered and described — vertical failure in the Upper Cretaceous — Lower Miocene deposits. An interesting feature of these structures is a close to isometric shape in plan. About 40 objects have been identified on an area of more than 1000 m2. «Bulls-eye» («multiphase») paleo-pockmarks [Andresen, Huuse, 2011], as well as karst collapse [Zuo et al., 2009] are proposed as world analogues with a similar wave pattern on seismic data.

AbstractWe present a detailed study of the stellar populations (SPs) and kinematics of the bulge and inner disk regions of nearby spiral galaxies (Sa-Sd) based on deep long-slit Gemini/GMOS data. We find that the SPs of spiral galaxies are not well matched by single episodes of star formation; representative SPs must involve average SP values integrated over the star formation history (SFH) of the galaxy, such as those derived from the “full population synthesis” method used here. Our spiral bulges follow the same correlations of increasing light-weighted age and metallicity with central veloc

Background: Patients with COVID-19 pneumonia may develop bullae that can rupture into spontaneous pneumothorax (SP) during the diagnosis and treatment, which can be a predictor of a poor prognosis.

Abstract:

Abstract The hair follicle (HF) is a complex mini-organ that constantly undergoes dynamic cycles of growth and regression throughout life. While proper progression of the hair cycle requires homeostatic interplay between the HF and its immune microenvironment, specific parts of the HF, such as the bulge throughout the hair cycle and the bulb in the anagen phase, maintain relative immune privilege (IP). When this IP collapses, inflammatory infiltrates that aggregate around the bulge and bulb launch an immune attack on the HF, resulting in hair loss or alopecia. Alopecia areata (AA) and primary

A numerical model based on the incompressible two-dimensional Navier–Stokes equations in the Boussinesq approximation is used to study mode-2 internal solitary waves propagating on a pycnocline between two deep layers of different densities. Numerical experiments on the collapse of an initially mixed region reveal a train of solitary waves with the largest leading wave enclosing an intrusional ‘bulge’. The waves gradually decay as they propagate along the horizontal direction, with a corresponding reduction in the size of the bulge. When the normalized wave amplitude, a, falls below the critic

His motor vehicle had crashed into a restaurant as a result of self-strangulation using an electrical cord wound four times around his neck. At autopsy, we found small rupture holes of spontaneous bullae in both lung apices, which had probably taken place upon collision during driving, petechial hemorrhages in the face skin and the absence of severe injuries. Since it seemed unlikely that the small holes in both lung apices caused fatal pneumothorax i

Both nuclei have a prominent ring or shell around them, giving the galaxy the appearance of a figure eight or an ∞ symbol.

Abstract Low-level winds along the Californian coast during spring and early summer are typically strong and contained within the cool, well-mixed marine boundary layer (MBL). A temperature inversion separates the MBL from the warmer free troposphere. This setup is often represented by a two-layer shallow-water system with a lateral boundary. Near a prominent point such as Point Conception, California, the fast-moving MBL flow is supercritical and can exhibit distinct features including a compression bulge and an expansion fan.

Four gas interfaces are considered with Atwood number ranging from $-0.18$ to 0.67. Results indicate that the diffracted convergent shock increases its strength gradually and reduces its amplitude quickly when it propagates towards the convergence centre. After the strike of the diffracted convergent shock, the initially unperturbed interface deforms with a bulge structure at the ce
