Production of Polyhydroxyalkanoates by Pseudomonas mendocina using vegetable oils and their characterisation
… (PHAs) by Pseudomonas mendocina, using different vegetable oils such as, coconut oil, groundnut oil, corn oil and olive oil, as the sole carbon source was investigated for the first time. The PHA yield obtained was compared with that obtained during the production of PHAs using sodium octanoate as …

‘The Development and Application of Novel Analytical Techniques in the Determination of Geographical Origin and Adulteration of Vegetable Oils'
… has led to olive oil being diluted with cheaper vegetable oils in an attempt to increase output and, therefore, profit. Some oil producing areas are considered to produce a superior quality olive oil and some suppliers import oil from other, less fashionable, areas and export the oil as 'bottled …

Influence of phytobland oils on the activity of foliarly applied atrazine
… (atrazine) as influenced by various phytobland oils was studied at three locations in Virginia. Postemergence control of grasses (Digitaria sanguinalis (L.) Scop., Panicum dichotomiflorum Michx., and Setaria spp.) was increased by single and repeated applications of atrazine in oil. However, no …

Formulation strategies in developing an oil-filled capsule for time-delayed release
… in which hydrophobic drugs were solubilised in vegetable oils was proposed. Two main components of the system, the swelling agent low-substituted hydroxypropylcellulose (grade LH-21) and brittle outer coating of ethylcellulose (EC) were individually characterised. Upon contact with water, LH-21 …

SUSTAINABLE FACE MILLING OF INCONEL 718 USING MQL AND NANOFLUIDS MQL WITH VEGETABLE OIL AS BASE FLUID
… CEC. Firstly, the research characterized three vegetable oils (High Oleic Soybean Oil (HOSO), Low Oleic Soybean Oil (LOSO), and Accu-lube Lb2000) and studied their rheological and thermal properties at varying temperatures (25 – 70 °C) compared to CEC. The result showed that the viscosity of all …

Fundamental properties and potential applications of two surfactant groups produced from renewable resources
… one by Biosid from natural raw materials such as vegetable oils and yeast proteins. Based on just a few properties and key data, it is now easy to judge whether a surfactant should be used and for what purpose, by comparing them with important characteristics of known surfactants. In addition to …
