Comparative cost-effectiveness analysis of Arctic and international shipping routes: A Fuzzy Analytic Hierarchy Process
(Elsevier, 2021)The cost-effectiveness of six Arctic route alternatives, including the Arctic routes likely to be opened in far future due to ice melting faster than expected stemming from the global warming, and current Suez and Panama ... -
Fault tree analysis of cargo leakage from manifold connection in fuzzy environment: A novel case of anhydrous ammonia
(Elsevier, 2021)Ammonia cargo requires special expertise in terms of handling, storage and transportation aspects as it is unquestionably one of the toughest goods carried by tankers due to its intrinsically dangerous properties. Any ... -
Development of Evaluation Procedures for Watchkeeping Officers Using Bridge Simulator
(Gdynia Maritime Univ, Fac Navigation, 2020)A comprehensive assessment of watchkeeping officers should be considered as a preventive measure in terms of safety of navigation. Watchkeeping officers are assigned after passing exams of state authorities and various ... -
Reshaping maritime university
(Nikola Vaptsarov Naval Academy, 2017)This study aims to investigate actions to reshape maritime universities from existing forms to more effective structure to meet full spectrum needs of the maritime sector in particular the research activities in support ... -

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 ... -
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 ... -
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 ... -
Static and dynamic structure of monomers, dimers and trimers of HgCl2 from density-functional calculations
(Springer, 2012)We report relativistic density-functional calculations for the equilibrium structures and the vibrational frequencies of the (HgCl2)(n) molecules with n = 1 to 3, as part of a broad exploration of the potential energy ... -
Chemical Reactivity Perspective into the Group 2B Metals Halides
(Amer Chemical Soc, 2016)Chemical reactivity descriptors within the conceptual density functional theory can be used to understand the nature of the interactions between two monomers of the Group 2B metal halides. This information might be valuable ... -
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, ... -
