Added Resistance of an AUV Moving Inside a Water Pipeline Due to Wall Proximity

International Journal of Maritime Technology, 2015
This paper evaluates the added resistance of a torpedo shape AUV, moving inside a water pipeline, due to wall effects within the tube. Today, there are long length pipelines of water or petroleum that need to regular inspection.

Analysis of Instantaneous Ship Resistance-Increase in Waves with CFD URANS

Polish Maritime Research
To comply with the requirements set out by the International Maritime Organization (IMO) for reducing greenhouse gas (GHG) emissions, recent efforts have focused on investigating the parameters that affect the increase in ship resistance, with the aim of

Analysis of Added Resistance in Short Waves

Journal of the Society of Naval Architects of Korea, 2015
In this study, the added resistance of ships in short waves is systematically studied by using two different numerical methods - Rankine panel method and Cartesian grid method - and existing asymptotic and empirical formulae. Analysis of added resistance in short waves has been preconceived as a shortcoming of numerical computation.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Comparison of CFD simulations with experimental data for a tanker model advancing in waves

International Journal of Naval Architecture and Ocean Engineering, 2011
In this paper, CFD simulation results for a tanker model are compared with experimental data over a range of wave conditions to verify a capability to predict the sea-keeping performance of practical hull forms. CFD simulations are conducted using WISDAM-

On a New Formulation for Wave Added Resistance [PDF]

, 2023
Our objective is to present preliminary calculations using a new formulation for the wave added resistance recently derived by Kashiwagi [1]. This method is based on far-field momentum conservation with the far-field integrals moved to the body using Green’s second identity. An incomplete form of this formulation with body-surface integrals has existed

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

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.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.
