To ensure the preservation and quality of the goods, physical (i.e. radiation) or chemical pest control is needed. The dark side of such consents may bear health risks in international transport and production sharing. In fact, between 10% and 20% of all containers arriving European harbors were shown to contain volatile toxic substances above the exposure limit values. Possible exposure to the...

The Maritime Education and Training (MET) instructors play an important role in maritime safety. They educate, train prepare new existing seafarers for efficient safe job performance ultimately shape the safety sustainability of shipping operations. To assist performing their tasks appropriately, International Organization (IMO) has developed various IMO model courses. paper addresses factors t...

Work is in progress at IMO-SLF on the development of so called "Second Generation Intact Stability Criteria". This development is expected to be embedded in a three-plus-one-tiers framework comprising vulnerability criteria of level 1 and 2, direct stability assessment and operational guidance. This paper presents two procedures for addressing parametric roll at a vulnerability level 1 and the ...

We consider a class of algebraic inequalities for functions of n variables depending on parameters that generalise the case of GA-convex functions. The functions in this class are GA-convex only in a subdomain of definition yet the inequality for GAconvexity still holds on the whole domain if suitable conditions are satisfied by the parameters. The method is elementary and allows us to give fur...

The procedures studied in this paper originate from a problem posed at the International Mathematical Olympiad in 1986. We present several approaches to the IMO problem and its generalizations. In this context we introduce a “signed mean value procedure” and study “relaxation procedures on graphs”. We prove that these processes are always finite, thus confirming a conjecture of Akiyama, Hosono ...

Janus methyl imogolite nanotube (Imo-CH 3 ) with a hydrophobic internal cavity and hydrophilic external surface, possessing permanently polarized thin wall, has been shown to act as dual photo-reactor for wastewater treatment simultaneous fuel production.

In this paper we propose a method to derive systolic designs with non-uniform data flow. One of the major difficulties in systematic design is in transforming the original sequential specification of a problem into a Conn suitable [0 VLSI implementation. Our approach [Q auromatically restructuring a problem is based on a subset of me data dependencies eXITacted from the original problem specifi...

Geometry is not only a part of mathematics with ancient roots but also a vivid area of modern research. Especially the field of geometry, called by some negligence “elementary”, continues to attract the attention also of the great community of leisure mathematicians. This is probably due to the small set of prerequisites necessary to formulate the problems posed in this area and the erudition a...
