Focusing on the scientific process of biomass compaction, the book provides an in-depth analysis of pressing chamber parameters and their impact on extrusion quality. It presents new insights into wood biomass pressing technology, detailing experimental research that defines how various chamber parameters affect mechanical quality indicators. The design and construction of an experimental pressing stand are also discussed, allowing for practical experimentation on the effects of technological and material parameters. Results are illustrated graphically to enhance understanding.

This book explores wood waste treatment as a solid biofuel through densification processes. It details experimental research on briquette production, analyzing parameters that affect density and optimizing densification machines. A mathematical model is presented to predict briquette density, benefiting both biofuel producers and academia.

Kniha prináša svedectvo o jednom z príbehov cirkvi v Československu v časoch komunistickej vlády. Nežná revolúcia priniesla v roku 1989 skrytej cirkvi, ktorá dovtedy pôsobila v podzemí, nielen oslobodenie, ale aj nové kontroverzie a zranenia. Nik to nevyjadril tak tvrdo a trpko - bez toho, že by sme chceli prikrášľovať hrôzy totalitného systému - ako Dušan Špiner, biskup skrytej cirkvi: „Nazývali nás aj umlčaná cirkev. Komunisti nás však neumlčali, ale až Vatikán."
