Application of human reliability analysis to repair & maintenance operations on-board ships: the case of HFO purifier overhauling
(Elsevier Sci Ltd, 2019)
Maintenance and repair at the operational level is a critical function to comply with the standard of competence for officers in charge of an engineering watch in a manned/unmanned ship engine room. The human factor in ...
Further Studies On the COLREGs (Collision Regulations)
(Gdynia Maritime Univ, Fac Navigation, 2015)
The collision risk is one of the major reasons threaten safety at sea. The Collision Regulations (COLREGs) is the essential international arrangement which regulates the rules of the roads at sea. Being also a legal document, ...
Effect of polyvinyl alcohol/chitosan blend ratios on morphological, optical, and thermal properties of electrospun nanofibers
(2019)
In this study, the electrospinning method was used to prepare polyvinyl alcohol (PVA)/chitosan (CS) blend nanofibers from their solutions. The effect of blend ratios (PVA/CS: 1%, 3%, 5%, and 7% (w/w)), applied voltage, and ...
Assessment of the impact of fouling on vessel energy efficiency by analyzing ship automation data
(Elsevier Sci Ltd, 2020)
Shipbuilding and shipping areas are technically dependent to each other since shipping is the end user in the shipbuilding industry. One of the biggest maritime challenges arose due to regulations about emissions and has ...
Structure of trimers of group-2B metal dihalides from relativistic density-functional calculations
(Taylor & Francis Ltd, 2015)
We report density-functional calculations, carried out in a quantum-chemical approach using localised-Gaussians expansions of the Kohn-Sham orbitals, for metal dihalides trimers (MX2)(3), where X=Cl, Br, or I and M=Zn, Cd, ...
The origins of tetrahedral coordination in molten and glassy ZnCl2 and other group-2B metal dihalides
(Elsevier, 2014)
We report the results of first-principles calculations carried out within a relativistic density-functional method, on the molecular trimers of the MX2 compounds (with M = Zn or Cd and X = Cl, Br, or I), showing how a ...
Superhydrophobic EVA copolymer fibers: the impact of chemical composition on wettability and photophysical properties
(Springer, 2018)
Fibers of poly(vinyl acetate) (PVAc) homopolymer and ethylene vinyl acetate (EVA) copolymers with varying vinyl acetate (VAc) contents between 25 and 40wt.% have been prepared to investigate wettability and photophysical ...
Effect of flow rate on wetting and optical properties of electrospun poly(vinyl acetate) micro-fibers
(Springer, 2019)
In this work, extremely hydrophobic micro-fibers from polyvinyl acetate (PVAc) were obtained by changing the flow rate of the solution in electrospinning process. Surface morphologies and wettability of the fiber surfaces ...
Synthesis of fluorinated polypropylene using CuAAC click chemistry
(Wiley, 2019)
Synthesis of fluorine containing polypropylene (PP-F) from chlorinated polypropylene (PP-Cl) via Cu(I) catalyzed Huisgen type 1,3-dipolar cycloaddition (CuAAC) and its water repellency properties are demonstrated. Initially, ...
The effect of drop size on contact angle measurements of superhydrophobic surfaces
(Royal Soc Chemistry, 2014)
In this study, the effect of drop volume on contact angle (CA) values and also on the applicability of the Cassie-Baxter equation is experimentally investigated. To do this, dimethyldichlorosilane (DMDCS) coated different ...
