Abstract:
Procedures based on solutions of the direct and inverse geodetic problems are presented and their application in orthodromic and loxodromic navigation is analysed. They can be used in traditional navigation during a route planning and during sailing on the planned route in real time. The optimal division of orthodromes during planning and locally predicted short loxodromes during sailing – which allow orthodromic navigation also in manual steering – are proposed.

This paper develops an approach to solving the problem of controlling the movement of a ship along a route. It is assumed that the route is specified using waypoints connected by line segments.

The gradient vectors of the selected auxiliary functions are directed towards the corresponding section of the vessel's route.

Abstract:
When an officer of the watch (OOW) faces complicated marine traffic, a suitable decision support tool could be employed in support of collision avoidance decisions, to reduce the burden and greatly improve the safety of marine traffic. Decisions on routes to avoid collisions could also consider economy as well as safety. Through simulating the biological evolution model, this research adopts the genetic algorithm used in artificial intelligence to find a theoretically safety-critical recommendation for the shortest route of collision avoidance from an economic viewpoint, combining the internat

Abstract:
A short enantioselective synthetic route to the cytotoxic marine natural product jaspine B has been developed. A chiral non-racemic primary α-allenol, obtained from pentadecanal, gave access to an enantioenriched 2-tetradecyl-2,5-dihydrofuran as key intermediate. A stereodivergent functionalization of this dihydrofuran allowed access in a few steps to jaspine B and its 4-epimer.

Abstract:
The bengazoles are marine natural products with unique structure, containing two oxazole rings flanking a single carbon. They show very potent antifungal activity. The total syntheses of bengazole C and E are described following a convergent route which involves diastereoselective cycloaddition of an appropriately substituted nitrile oxide with a butane-1,2-diacetal-protected alkenediol as the key step.

Abstract:
Electronic Chart Display and Information Systems (ECDIS) technology has recently emerged as a promising aid to maritime navigational safety and operational efficiency. ECDIS is likely to have multiple effects on the tasks bridge personnel must perform. However, careful consideration must be given to safety in adopting this new technology. A shiphandling simulator-based evaluation of some human factors aspects of the use of ECDIS is presented. The issues discussed include the effect on navigational safety and workload as a result of introducing ECDIS to the bridge, and the mariner's preference

Recently more and more evidence appears, proving that seafood consumers should be referred to risk group in which outbreaks of viral food poisoning and foodborne infectious diseases occurs, transmitted by food route. There are several reasons to refer seafood to a category of epidemiologically non-safe products: high microbial pollution of adjacent seas with sewage waters; many non-fish hydrocoles are natural filter feeding animals, which are infected by viruses in the process of vital activity, passing through their organism water and food particles; sufficient viruses stability in external e

Abstract:
The paper presents the results of research on measuring the emissions from marine diesel engines in dynamic states. The problem is as follows: How to measure emissions of the composition of exhaust gases on board a ship, without direct measurement of fuel consumption and an air flow to marine diesel engine, during maneuvering the ship in the port area. The authors proposed a measurement methodology using an exhaust gas analyzer with simultaneous recording of the load indicator, engine speed, inclinometer, and Global Positioning System (GPS) data. Fuel consumption was calculated based on mean i

Hence, a content analysis of the Instagram accounts of the MWH of Outstanding Universal Value (OUV) sites and protected areas has been conducted. The study included evidence from their Instagram p

Abstract:
AbstractAt the end of the twentieth century, Russia's Northern Sea Route (NSR) has functioned primarily as a domestic marine transport system with Murmansk Shipping Company as the dominant operator and facilitator. Total cargo along the NSR in 1999 was 1.58 million tons; during 1997–99 no through transit cargo was carried on the NSR. The International NSR Programme (INSROP), backed by Japanese, Norwegian, and Russian interests, concluded in November 1999 with a key user conference in Oslo. The six-year (1993–99) INSROP effort produced a large body of new information about the NSR and Russian A
