The study's aim was to create a brightness histogram based on the electrical effects of a 1% solution of lavender essential oil dissolved with 5% ethyl alcohol in distilled water compared to a control sample of 5% ethyl alcohol in distilled water. Corona gas discharge (CGD) is a glowing corona with a bluish color that appears because of a high concentration of ions and electrons. The corona discharge is connected to ionization processes in the gas phase, which depend on the electric field and gas composition. CGD occurs in laboratory conditions. Corona can have a positive or negative charge. Both types are used for wastewater cleaning, fruit juice sterilization, surface disinfecting, and medicine. A high-voltage electrode usually ranges from 3 to 30 kV. The frequency range was from 10 to 20 kHz. The electric current is commonly in mA. Ignatov et al. have studied signal power ranges from one to two-tenths of a watt. Antonov et al. have shown that CGD parameters depend on the object's dielectric permittivity, underscoring the importance of this research. The work of Pesotskaya et al. is also of significance to this study. It indicates that BH can be created with black-white registration and that brightness is linked with dielectric permittivity. This finding is particularly relevant to this research about the effects of CGD on lavender oil (LO) from the Lavandula angustifolia mill., as it provided a method for quantifying observed changes in brightness. The formula is Y = C epsilon, where Y is brightness, C is coefficient and epsilon is dielectric permittivity.

In 2007, a study was done using color corona spectral analysis [39]. The method was applied in laboratory conditions with the coronal glow of biological objects and liquids. A high voltage of 12 kV and a frequency of 15 kHz have been applied during the research. In 1995, Antonov created the apparatus for the study, with registration in black and white photographic films. The scientist called the method selective high-frequency discharge. It has been categorized as silverless photography. In the presence of electrical conditions, electrography is at the heart of the photocopier invention. Herein, CaCO3 in a distilled H2O solution was tested. Comparative analysis was performed with distilled H2O. Physical and chemical processes under high-frequency corona gas discharge conditions were analyzed. CaCO3 was in dynamic interaction with CO2 and H2O at the boundary of different environments.

Lithium-ion batteries risk failing when subjected to different abuse tests, resulting in gas and flames. In this study, 5 Ah nickel manganese cobalt oxide (NMC) pouch cells were subjected to external heating; overcharge at rates of 2.5, 5 and 10 A; and nail penetration. Tests were conducted in air and N2 atmospheres. Additional external heat tests were performed on cells at 5, 25, 50, and 75% SoC and on two, three, and four cell blocks. Gas volumes were calculated, and the gas composition was given for H2, CO, CO2, C2H4, C2H6, CH4, C3H6, and C3H8. For tests under an air atmosphere at 100% SoC, the volume of gas varied between abuse methods: 3.9 L (external heat), 6.4 L (overcharge), and 8.9 L (nail penetration). The gas composition was found to predominantly contain H2, CO2, and CO for all abuse methods; however, higher concentrations of H2 and CO were present in tests performed under N2. External heat tests at different SoCs showed that the gas volume decreased with SoC. Overall, the type of abuse method can have a large effect on the gas volume and composition produced by cell failure.

Corona gas discharge (CGD) is a physical process that occurs when a gas is ionized. It is observed as a bluish glow at high breakdown voltages from 5 to 30 kV. In laboratory conditions, [1] has objectively studied CGD, in the former USSR, in the late 1940s. The method was classified as electrophotography, for recording information. Based on an electrophotographic information recording, Carlson developed xerography in the 1960s. [3] has conducted experiments using electrophotographic CGD methods, to record data. Antonov and co-authors proved that CGD primarily depends on the object's dielectric permeability rather than on conductivity. [15, 16] have measured photon emission in different types of water. The method is called color coronal spectral analysis. Since 2012, [12] have developed a method for analyzing CGD image, assessing brightness for various water types. The authors consider that, with CGD, information is connected with water dielectric permeability and, thus, with H2O molecules restructuring. The developed method of water classification allows for an integral assessment of H2O characteristics. The experimental sample was classified based on brightness histogram (BH) analysis of CGD radiation images.

Water is a critical nutrient in poultry production, yet its quality, particularly dissolved oxygen (DO) content, is often overlooked. This study is the first to comprehensively evaluate the impact of oxygen-enriched drinking water on broiler welfare, breast muscle myopathies, and gut microbiome composition under commercially relevant housing conditions. A total of 840 male Ross 308 broiler chicks were randomly assigned to two treatment groups (oxygenated water vs. tap water), with 12 replicate pens per treatment. Oxygenated water was enriched to a DO level of approximately 32 mg/L, compared to around 9.5 mg/L in tap water. Birds were reared to 36 days of age. The consistently high performance of both treatment groups under controlled experimental conditions is demonstrated by final body weights and feed conversion ratios surpassing Ross 308 breed standards by approximately 19–22 % from day 24 onward. Although growth performance remained unaffected under these optimal conditions, oxygenated water significantly improved welfare indicators, including feather condition, hock burn scores, and breast cleanliness (P< 0.05). Birds on oxygenated water also showed lower abdominal fat (−12 %) and higher thigh yield (+2.6 %) without compromising breast yield. Carcass fat deposition was significantly lower (abdominal fat pad reduced by ∼12 %), and thigh yield was higher in the oxygenated water treatment (P < 0.05), although overall carcass weight and breast yield were unchanged. No major differences were detected in breast meat nutrient composition (P > 0.05). The prevalence of white striping in breast fillets was markedly reduced in birds receiving oxygenated water, 32 mg/L indicating enhanced muscle integrity (P < 0.05). Metagenomic analysis revealed that some bacterial lipid metabolism pathways where differentially abundant in oxygenated-water birds. Following up on previous knowledge suggesting the interplay between lipid metabolism and broiler welfare, these findings suggest that supplementing broiler drinking water with 32 mg/L DO levels may offer a practical, non-pharmaceutical strategy to mitigate breast muscle myopathies and improve overall animal welfare and meat quality.
