Healing Beams: Radiation and Radiotherapy in Novels, Poems, Music, Film, Painting

Journal of Medical Radiation Sciences, EarlyView.
Radiation and radiotherapy are perceived by patients and the general public as mysterious, dangerous and healing. The image of radiation and radiotherapy can be analysed by studying novels, poems, music, film and painting. Our paper reviews how radiation and radiotherapy are perceived by patients, the general public, as reflected in various art genres.

Asymptotic models for the generation of internal waves by a moving ship, and the dead-water phenomenon

, 2011
This paper deals with the dead-water phenomenon, which occurs when a ship sails in a stratified fluid, and experiences an important drag due to waves below the surface.

Relationships between acoustic scattering layers and ocean stratification: An acoustic approach to estimate mixed layer depth

Limnology and Oceanography: Methods, EarlyView.
Abstract Ocean stratification, measured as mixed layer depth (MLD), is an important feature that influences many processes in the ocean; for example, by mediating the fluxes of momentum, heat and crucially key gases such as CO2 and oxygen from the atmosphere into the water column and vice versa. The conventional methods to measure stratification (e.g.,

Numerical study of ship motions and added resistance in regular incident waves of KVLCC2 model

International Journal of Naval Architecture and Ocean Engineering, 2017
In this study, the numerical investigation of ship motions and added resistance at constant forward velocity of KVLCC2 model is presented. Finite volume CFD code is used to calculate three dimensional, incompressible, unsteady RANS equations.

Development of a moored radium in situ sampler to measure annual time series

Limnology and Oceanography: Methods, EarlyView.
Abstract Radium is a useful tracer of sediment‐derived materials, improving our understanding of the geochemical cycling of elements at ocean boundaries. We have developed an autonomous in situ sampler to collect time series samples of radium isotopes on mooring deployments.

Numerical Insights Into the Resistance Reduction Mechanisms of Forward Tapered Transoms in High‐Speed Catamaran: A Computational Fluid Dynamics‐Based Study

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study investigates the hydrodynamic influence of forward transom tapering on a displacement catamaran hull using computational fluid dynamics (CFD) simulations. Five taper configurations ranging from a vertical transom base design to a fully tapered stern (1.00B) were evaluated over a wide Froude number range (Fr = .3 to 1.0).

Single Smooth Waveform Command‐Shaping Control of Overhead Crane Systems Utilizing Two‐Stage Acceleration–Deceleration Profile for Short‐Moving Point‐to‐Point Maneuver

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern industrial demand for efficient material handling in confined spaces has driven the need for overhead cranes capable of short‐distance point‐to‐point maneuvers without compromising payload stability. Conventional three‐stage shaper profiles, experiencing acceleration, cruising, and deceleration, become inefficient or infeasible for ...
