In this paper, the design and research of a oljelampe sensor-based personal air-quality monitoring device are presented, which is retrofitted into different personal protective face masks.Due to its small size and low power consumption, the device can be integrated into and applied in practical urban usage.We present our research and the developmen
A study was conducted to evaluate the effect of inulin from Asparagus falcatus and Taraxacum javanicum on ar-13995n growth of Lactobacillus acidophilus (La-5) and Bifidobacterium animalis (Bb-12) in skim milk.Commercially available chicory inulin and chicory fructooligosaccharides (FOS) were used as positive controls.Skim milk (13% (w/v)) samples s
Coronaviruses are positive sense, single-stranded, enveloped, and non-segmented RNA viruses that belong to the Coronaviridae family within the order Nidovirales and suborder Coronavirinae.Two Alphacoronavirus strains: HCoV-229E and HCoV-NL63 and five Betacoronaviruses: HCoV-HKU1, HCoV-OC43, SARS-CoV, MERS-CoV, and SARS-CoV-2 have so far been recogn
This paper explores the physics of chaos in a localized phase-space region produced by rf phase modulation applied to a double rf system.The study can be exploited to produce rapid particle bunch broadening exhibiting longitudinal particle distribution uniformity.Hamiltonian models and particle-tracking simulations are introduced superhero lollipop
In this article, the performance of an inclined north-south axis (INSA) multiple positions sun-tracked V-trough with restricted reflections for photovoltaic applications (MP-VPVs) is investigated theoretically based on the imaging principle of mirrors, solar geometry, vector algebra and three-dimensional radiation transfer.For such a V-trough photo
