Kinetics of vapor-liquid and vapor-solid phase separation under gravity.
Soft Matter

Department of Physics, School of Advanced Sciences, Vellore Institute of Technology, Vellore, Tamil Nadu 632014, India.
We study the kinetics of vapor-liquid and vapor-solid phase separation of a hydrodynamics preserving three-dimensional one-component Lennard Jones system in the presence of an external gravitational field using extensive molecular dynamic simulation. A bicontinuous domain structure is formed when the homogeneous system near the critical density is quenched inside the coexistence region. In the absence of gravity, the domain morphology is statistically self-similar and the length scale grows as per the existing laws.

Electric heaters are widely used owing to their portability, fast heating, single-focus heating, and energy efficiency advantages. Manufacturers provide customers with information on the power consumption and energy efficiency classes of heaters but do not provide any information on heating patterns. Knowing the heating pattern enables users to select the correct heater, which has a significant effect on comfort, health, energy efficiency, industrial process performance, plant growth, and climate change.

Background: Spread of local anaesthetic solution in the paravertebral space after erector spinae plane block (ESPB) is variable. We evaluated whether paravertebral spread of local anaesthetic is affected by patient position after ESPB.
Methods: We randomised 84 patients to receive ESPB at T with a mixture of 0.
Dimensions and position of the eye for facial approximations in a South African cone beam computed tomography sample.

Accurate population and sex-specific normative values for the orbital and ocular dimensions, including the position and protrusion of the eye relative to the orbital rim, are vital for reliable facial approximations. In studies utilizing cadaveric tissue and computed tomography scans, the observed measurements may be influenced by desiccation, distortion or gravity, respectively. This study assessed the dimensions of the eye and orbit and established the position and protrusion of the eye relative to the orbital margin using cone beam computed tomography (CBCT) scans to negate the effect of gravity in the supine position.

Department of Thoracic and Cardiovascular Surgery, Ansan Hospital, Korea University College of Medicine, Ansan-si, Republic of Korea.
Background: In the process of video-assisted thoracoscopic surgery (VATS) for lung nodule resection, lung is leaded to atelectasis. However, preoperative computed tomography (CT) images are taken during inspiration, which means they differ significantly from the lung status observed during surgery. Consequently, this discrepancy can make the localization of small or subsolid nodules challenging during the operation.
