IMPULSE NOISE ASSOCIATED WITH FIRING HANDHELD MILITARY WEAPONS
PublicationSports, hunting and military shooting grounds are well known sources of noise that can be disruptive both for people present at those facilities, as well as for people and animals that live nearby. What is more, shooters are also subjected to very painful and dangerous impulse noise. The paper discusses the issues related to the noise immission during firing of small firearms of military type that are typical for Poland. The experiments...

Module architecture as alternative approach to traditional construction processes
PublicationModule architecture today is a special type of building construction process that combines repetitive design, low-cost production based on prefabricated elements and fast erection. Module does not mean the same as modular. In general, module architecture today refers to the design of any system composed of separate components, manufactured before in factory, that can be connected together at the building site much faster than normally....

ROLE OF GREEN LOGISTICS IN THE CONSTRUCTION OF SUSTAINABLE SUPPLY CHAINS
PublicationThe global supply chain has been growing strongly in recent years. This development brings many benefits to the economy, society, and human resources in each country but also causes a large number of concerns related to the environment since traditional logistics activities in the supply chain have been releasing significant amount of emissions. For that reason, many solutions have been proposed to deal with these environmental...

Universal construction of genuinely entangled subspaces of any size
PublicationWe put forward a simple construction of genuinely entangled subspaces – subspaces supporting only genuinely multipartite entangled states – of any permissible dimensionality for any number of parties and local dimensions. The method uses nonorthogonal product bases, which are built from totally nonsingular matrices with a certain structure. We give an explicit basis for the constructed subspaces. An immediate consequence of our...

Superstitions and customs in construction - a contribution to the discussion on the disappearance of this tradition
PublicationConstruction is one of the most important, but also the most extensive areas of the economy. That is why we encounter superstitions and customs related to this discipline of the economy quite often:we blew and repeat them, not even knowing what their origin is and what according to old beliefs resulted in their lack of application. This situation applies in practice to all buildings, including residential buildings implemented...
