Wystawa Black Out #3, Zbrojownia Sztuki
Publikacja -
Inteligentne częstotliwościowo - napięciowe odciążanie w systemie elektroenergetycznym. Black-Out a Krajowy System Elektroenergetyczny.
PublikacjaW pracy podano, że automatyka samoczynnego odciążenia w Krajowym Systemie Elektroenergetycznym została wprowadzona z dwóch powodów. 1. W celu obrony całego systemu przed przeciążeniem i w rezultacie - załamaniem częstotliwości przy często występujących globalnych deficytach mocy. 2. W celu obrony ''wysp'' lub podsystemów w czasie awarii systemowych, powodujących rozpadnięcie się systemu na części.

On the use of black tea waste as a functional filler for manufacturing self-stabilizing polyethylene composites: In-depth thermal analysis
PublikacjaThermal and oxidative stabilization are critical aspects in the processing and exploitation of polyolefins. Black tea contains many natural antioxidants, the largest group of compounds in its composition. When used as a filler for composite manufacturing, the thermo-oxidation process of polyethylene can be slowed down. Black tea waste (BTW) generated during the process of packing tea into sachets was introduced into a bio-based...

Hydro Power Plant in the Process of Voltage Control in the Electric Power System and the System Restoration
PublikacjaThe article covers selected issues related to the share of hydroelectric power in the process of rebuilding the power system after black-out and voltage control during that process. Selected results of measurements made during the creation of the transmission chain for the need to start a block of a thermal power plant from a hydroelectric power plant were presented.

Investigating the combined effects of devulcanization level and carbon black grade on the SBR/GTR composites
PublikacjaCarbon black migration between ground tire rubber (GTR) and rubber matrix is essential in developing high-performance rubber/GTR composites. In this work, carbon black N220 (surface area: 107.1 m2/g, particle size: 20–25 nm) andN660 (surface area: 33.1 m2/g, particle size: 49–60 nm) were used as the reinforcement fillers for styrene-butadiene rubber(SBR) blended with reclaimed GTR. The combined effects of GTR devulcanization level...

Edible black ant Smith (Carebara vidua) as human food – A systematic review
PublikacjaMeeting food security is one of the major global challenges to ensure sufficient supply of food for current and future generations, considering increasing population growth and climate change issues. Consequently, the consumption of edible insects as an alternative food source has recently gained global attention for combating global food insecurity. The present review aims to provide information on the recent progress in consumption...

Structural, optical and electrochemical performance of black phosphorus and black arsenic-phosphorus nanostructures
PublikacjaBlack phosphorus (BP)-based nanostructures have drawn a lot of attention due to their tunable bandgap and extraordinary properties such as: high surface-to-volume ratio, large number of active sites, and prominent edges. However, low dimensional structures of black phosphorus oxidize easily, which hamper their application on a broader scale. One way to overcome these difficulties is to modify the black phosphorus structure by substituting...

Typology of the Black Tents Architecture between Iranian nomad tribes
PublikacjaEvidence of the past shows variation in human settlements. Nomadic house the” Black Tent” shows relationship between humans and the natural environment surrounding them. Black Tents are made of natural materials consistant with environmental conditions. This paper discusses nomadic living space of some Iranian tribes located in different regions to show their unique architecture and culture. Rediscovering different architecture...

Study of the Operation of Synchronous Generator Voltage Regulator During the Creation of Post Blackout Start-up Path
PublikacjaThis paper presents the influence of automatic voltage regulator (AVR) of synchronous generator on the process of creation of post black-out start-up path. Two elements of AVR have a significant impact on this process: underexcitation limiter (UEL) and load compensation (LC). The authors present a theoretical investigation and simulation results that illustrate how the mentioned elements of AVR affect voltage levels in a power...
