This paper presents novel research on the development of a generic intelligent oil fraction sensor based on Electrical Capacitance Tomography (ECT) data. An artificial Neural Network (ANN) has been employed as the intelligent system to sense and estimate oil fractions from the cross-sections of two-component flows comprising oil and gas in a pipeline. Previous works only focused on estimating the oil fraction in the pipeline based on fixed ECT sensor parameters. With fixed ECT design sensors, an oil fraction neural sensor can be trained to deal with ECT data based on the particular sensor parameters, hence the neural sensor is not generic. This work focuses on development of a generic neural oil fraction sensor based on training a Multi-Layer Perceptron (MLP) ANN with various ECT sensor parameters. On average, the proposed oil fraction neural sensor has shown to be able to give a mean absolute error of 3.05% for various ECT sensor sizes.

The transformation and risk assessment of flavonoids triggered by free radicals deserve extensive attention. In this work, the degradation mechanisms, kinetics, and ecotoxicity of kaempferol and quercetin mediated by ∙OH, ∙OCH, ∙OOH, and O in gaseous and aqueous environments were investigated using cell experiments and quantum chemical calculations. Three radical scavenging mechanisms, including hydrogen atom transfer (HAT), radical adduct formation (RAF) and single electron transfer (SET) were discussed.

Orthotopic tumor models in pre-clinical translational research are becoming increasingly popular, raising the demands on accurate tumor localization prior to irradiation. This task remains challenging both in X-ray and proton computed tomography (xCT and pCT, respectively), due to the limited contrast of tumor tissue compared to the surrounding tissue. We investigate the feasibility of gadolinium oxide nanoparticles as multimodal contrast enhancement agent for both imaging modalities.

Background: Scabies is a debilitating and neglected infectious disease with limited effective treatment options and affecting millions of people worldwide, mainly in poor and overcrowded settings. Essential oils from Australasian Myrtaceae are known to have parasiticidal properties, often attributed to the presence of β-triketones, which are known inhibitors of the tyrosine catabolism pathway through inhibition of hydroxyphenylpyruvate dioxygenase (HPPD).
Purpose: In this study, essential oils from mānuka (Leptospermum scoparium) were evaluated in vitro for miticidal and ovicidal activities and their active β-triketone constituents (flavesone, leptospermone, and isoleptospermone) were identified.

Millions of men and women suffer from alopecia, especially androgenic alopecia (AGA), which is considered the most common form of hair loss. The available treatments for hair loss include multiple approaches, with the most popular being synthetic drugs including minoxidil and finasteride, in addition to natural products. However, synthetic drugs have shown many undesirable side effects, on the contrary, the specifications of the commonly used natural drugs have not been reported in most of the previous studies, despite the high market preference for them.

Effect of different evening primrose oil content (1-20 %) on the rheological, mechanical, textural and microstructure of furcellaran/whey protein isolate emulsion gels were investigated at neutral, unmodified pH environment. The results indicate that, irrespective of the concentration, the oil acted as an inactive filler and was not chemically bound in the polymer network but only physically immobilized in it. The increasing oil amount in the material from 1 to 20 % resulted in a percentage decrease in hardness (52 %), gumminess (71 %) and stress relaxation ratio (17 %) which means that presence of the hydrophobic components weakens the structure of the material, but all samples exhibit elastic behaviour.
