Analiza nośności zabytkowych fundamentów w kontekście jakości użytych zapraw Analysis of the Load-Bearing Capacity of Historical Foundations in the Context of the Quality of Mortar Used
PublicationStructures of historical buildings usually have the form of masonry elements. The weakest component of such elements is mortar, especially in stone foundations, which were often used in the with a focus on the modeling of mortar as a joint connecting stones in a characteristic medieval foundation. Different types of mortar: cement, cement-lime, lime and gypsum mortars, were examined. A numerical analysis was carried out on the...

Daytime Acute Non-Visual Alerting Response in Brain Activity Occurs as a Result of Short- and Long-Wavelengths of Light
PublicationVery recent preliminary findings concerning the alerting capacities of light stimulus with long-wavelengths suggest the existence of neural pathways other than melatonin suppression that trigger the nonvisual response. Though the nonvisual effects of light during the daytime have not been investigated thoroughly, they are definitely worth investigating. The purpose of the present study is to enrich existing evidence by describing...

Instantaneous power signal measurements for bearing diagnostics
Open Research DataBearing diagnostics can be carried out based on the method, which relies on the measurement and analysis of the variability of the signal instantaneous power, defined as the product of instantaneous current and voltage power supplied to the engines. Bearing damage causes the appearance of deformations, which are in the form of additional harmonic components...

PANTOGRAPH AS AN EXAMPLE OF THE USE OF GEOMETRIC TRANSFORMATIONS IN CONSTRUCTING OF OLD DRAWING INSTRUMENTS = PANTOGRAF JAKO PRZYKŁAD ZASTOSOWANIA PRZEKSZTAŁCEŃ GEOMETRYCZNYCH W KONSTRUOWANIU DAWNYCH PRZYRZĄDÓW KREŚLARSKICH
PublicationThe article describes the pantograph, considered to be the ancestor of today's photocopier. This instrument draws the copies, enlarges or reduces any figure. The author presents its genesis, the scope of application in the past, explains the structure and geometrical transformations used during its action. Based on a specific example, the work illustrates practical application of geometry in the past inventions for designing.

Does the carbon emissions trading system reduce carbon emissions by promoting two-way FDI in developing countries? Evidence from Chinese listed companies and cities
PublicationHow developing countries can effectively promote cities’ carbon emission reduction through the carbon emission trading system (ETS) is a topic worthy of attention in the global carbon reduction campaign. Policy changes in China's ETS provide a unique opportunity to measure whether ETS impacts carbon emissions through two-way FDI. Hence, this paper employs difference-in-differences (DID) method to test the causal impact of ETS...

Brain circuit imprints of developmental 17α-Ethinylestradiol exposure in guppies (Poecilia reticulata): Persistent effects on anxiety but not on reproductive behaviour
PublicationThe effects of endocrine disruptors may vary with the timing of exposure. The physiological implications of adult exposure are present during and shortly after exposure while embryonic exposure can imprint changes manifested in adulthood. In this study, guppy (Poecilia reticulata) embryos were exposed to 2 and 20 ng/L of 17α-ethinylestradiol during development via the mother and reared in clean water from gestation until 6 months...

Natural fish oil improves the differentiation and maturation of oligodendrocyte precursor cells to oligodendrocytes in vitro after interaction with the blood–brain barrier
PublicationThe blood–brain barrier (BBB) tightly controls the microenvironment of the central nervous system (CNS) to allow neurons to function properly. Additionally, emerging studies point to the beneficial effect of natural oils affecting a wide variety of physiological and pathological processes in the human body. In this study, using an in vitro model of the BBB, we tested the influence of natural fish oil mixture (FOM) vs. borage oil...
