Calculation Methods of Icebreaking Capability for a Double-Acting Polar Ship
Journal of Marine Science and Engineering, 2020 As a key parameter, icebreaking capability is often used to judge whether a polar ship could navigate in level ice at a certain speed. This paper presents two methods to calculate icebreaking capability.

Experimental Study on the Ice Resistance of a Naval Surface Ship with a Non-Icebreaking Bow
Journal of Marine Science and Engineering, 2023 With the shrinking of Arctic sea ice due to global climate change, potential access to Arctic waters has increased for non-typical icebreaking or strengthened ships. Numerous studies have been conducted on hull form designs and ice resistance predictions

Study on icebreaking performance of the Korea icebreaker ARAON in the arctic sea
International Journal of Naval Architecture and Ocean Engineering, 2011 A full-scale field trial in ice-covered sea is one of the most important tasks in the design of icebreaking ships. The first Korean icebreaking research vessel ‘ARAON’, after her delivery in late 2009, had a sea ice field trial in the Arctic Sea during ...

International Journal of Naval Architecture and Ocean Engineering, 2016 Recent icebreaking ships need to be designed to enhance not only icebreaking capability but also turning ability. For the evaluation of ice resistance induced by an icebreaking hull form, HHI (Hyundai Heavy Industries) has developed the hybrid empirical ...

Experimental and numerical study on ice resistance for icebreaking vessels
International Journal of Naval Architecture and Ocean Engineering, 2015 Ice resistance is defined as the time average of all longitudinal forces due to ice acting on the ship. Estimation of ship’s resistance in ice-covered waters is very important to both designers and shipbuilders since it is closely related to propulsion ...

Enhancing System Empathy Within a UK Emergency Department: A Feasibility Interprofessional Priority Setting Exercise. [PDF]
J Eval Clin PractABSTRACT Rationale Empathy in healthcare benefits patients and practitioners, yet system‐level barriers inhibit empathy. The barriers include burnout‐inducing administrative workloads, burdensome protocols, lack of wellbeing spaces, un‐empathic leadership, and not emphasising empathy as an institutional value.

Experimental Study on IRV Ramming Artificial Model Ice
Journal of Marine Science and Engineering, 2023 When the icebreaker sails in the polar region, it adopts continuous and ramming icebreaking operations. When the ice condition exceeds the design working condition, it uses the ramming icebreaking method to advance.

Numerical Simulation of the Ice Breaking Process for Hovercraft
Journal of Marine Science and Engineering, 2021 A hovercraft can adapt to an ice area, open water, land and other environments, owing to its unique hull structure. It also plays an important role in transporting supplies, rescuing people, breaking ice and conducting other tasks. Ice load prediction is

A Mixed Method Study Exploring Children and Young People's Perception of Energy Drinks and Analysing Consumption Patterns. [PDF]
J Hum Nutr DietABSTRACT Background Sales and consumption of energy drinks (EDs) continue to rise, especially amongst young people, yet the reason remains unclear. In 2018, a campaign by Jamie Oliver resulted in a voluntary sales ban to under 16‐year‐olds. Also in 2018, the Department of Health and Social Care ran a consultation to end the sales of EDs to under 16 s ...
