Olive Oil Composition: Volatile Compounds [PDF]
, 2012 In general olive oil is defined on the basis of its sensory characteristics. European Union (EU) regulations establish the organoleptic quality of virgin olive oil by means of a panel test, evaluating positive and negative descriptors (EU regulations).

Emergence of Turbulent Epochs in Oil Prices [PDF]
, 2018 Oil price data have a complicated multi-scale structure that may vary with time. We use time-frequency analysis to identify the main features of these variations and, in particular, the regime shifts. The analysis is based on a wavelet-based decomposition and analysis of the associated scale spectrum.

Cyclical properties of supply-side and demand-side shocks in oil-based commodity markets [PDF]
arXiv, 2016 Oil markets profoundly influence world economies through determination of prices of energy and transports. Using novel methodology devised in frequency domain, we study the information transmission mechanisms in oil-based commodity markets. Taking crude oil as a supply-side benchmark and heating oil and gasoline as demand-side benchmarks, we document ...

Value relevance of the components of oil and gas reserve quantity change disclosures of upstream oil and gas companies in the london stock exchange [PDF]
arXiv, 2020 The high level of risk and uncertainty in harnessing oil and gas reserves poses an accounting dilemma in the reporting of reserves quantity information; information which is critical and relied on by investors for decision making. Different studies have indicated that reserves disclosure information is fundamental to understanding the value of the firm.

Advanced Materials Interfaces, EarlyView.Due to the Schiff base reaction between polyethyleneimine and glutaraldehyde in the aqueous phase, a pH‐responsive interfacial film is constructed at the interface of the two immiscible phases. Consequently, both pH‐reversible high internal phase emulsions and pH‐controlled release capsules can be easily fabricated using this emulsion system.
