“Force Majeure”, Extension Of Time Clauses And The Prevention Principle In Shipbuilding Contracts, Zoran Tasic May 2025

“Force Majeure”, Extension Of Time Clauses And The Prevention Principle In Shipbuilding Contracts, Zoran Tasic

Seatific Journal

Under English law, it is entirely up to the contract parties to agree on “force majeure” events that are beyond the builder’s control. Under an old English law principle known as the “prevention principle”, no party to a contract should be allowed to benefit from its own failure to perform. In the context of shipbuilding contracts, this principle should give protection to a shipyard in the case of delays in the delivery of a vessel that are caused by the buyer’s defaults. It is the builder’s fundamental duty to deliver the vessel to the buyer on the delivery date set …

A Domestic Waste Heat Recovery System: Mathematical Model Of A Green Kitchen Module, Stefano Maria Spagocci May 2025

A Domestic Waste Heat Recovery System: Mathematical Model Of A Green Kitchen Module, Stefano Maria Spagocci

Seatific Journal

A lumped parameter model of a domestic heat storage/recovery system is described. This is a typical green kitchen application, where the heat dissipated by kitchen appliances is stored in suitable materials by temperature rise and/or phase transitions. To this aim, sensible heat materials and phase change materials are considered. Based on the model, a number of design solutions are proposed, making use of fixed beds or shell-and-tube heat exchangers, where heat is stored in spheres or cylinders made up of (or encapsulating) suitable materials. The best solution (a PCM-based shell-and-tube exchanger) corresponds to ~50×50×25 cm, ~30 kg modules.

Maximum Entropy Production And Constructal Law: Variable Conductance And Branched Flow, Phillip Johnson May 2025

Maximum Entropy Production And Constructal Law: Variable Conductance And Branched Flow, Phillip Johnson

Seatific Journal

Within the scope of modern thermodynamics, several new principles have been advanced. Yet a coherent picture has not yet fully emerged beyond classical thermodynamics, in part because of the disparate nature of these principles. This work analyzes two such principles, that of maximum entropy production and also the constructal law. These ideas are compared in two examples scenarios, atmospheric convection and riverbed generation. It is shown that both ideas utilized a flow network with variable conductivity, particularly that of a branched system. Comparison is made to show underlying shared principles.

“Crusades Against Bolshevism”?: International Dimensions Of The Russian Civil War In Four Countries, Maxwell R. Markwald May 2025

“Crusades Against Bolshevism”?: International Dimensions Of The Russian Civil War In Four Countries, Maxwell R. Markwald

Student Scholarship

The Russian Civil War (1917-1922), fought between Bolshevik and anti-Bolshevik factions, was one of the most pivotal conflicts of the 20th century. It led directly to the rise of the world’s first socialist state, the Soviet Union, which for decades was at the forefront of the international communist movement and a major global power until its collapse in 1991, around 70 years after its founding. The victory of the Bolsheviks was not always a guaranteed outcome, however. In fact, to an outside observer in February of 1917, it would have appeared one of the less likely. The six months that …
