Classification of olive cultivars by machine learning based on olive oil chemical composition.

Extra virgin olive oil traceability and authenticity are important quality indicators, and are currently the subject of exhaustive research, for developing methods to secure olive oil origin-related issues. The aim of this study was the development of a classification model capable of olive cultivar identification based on olive oil chemical composition. To achieve our aim, 385 samples of two Greek and three Italian olive cultivars were collected during two successive crop years from different locations in the coastline part of western Greece and southern Italy and analyzed for their chemical characteristics.

Chemometric Discrimination of the Geographical Origin of Three Greek Cultivars of Olive Oils by Stable Isotope Ratio Analysis.

Α stable isotope ratio mass spectrometer was used for stable isotope ratio (i.e., δC, δO, and δH) measurements, achieving geographical discrimination using orthogonal projections to latent structures discriminant analysis.

A negative association between lithium in drinking water and the incidences of homicides, in Greece.

The purpose of the present study was to evaluate the association between lithium levels in the public water supply and incidences of homicide in Greece. A total of 149 samples of drinking water were collected from 34 out of 52 prefectures, and data for homicides were taken from National Statistic Service of Greece (Hellenic Statistical Authority - EL.STAT).

Composted versus raw olive mill waste as substrates for the production of medicinal mushrooms: an assessment of selected cultivation and quality parameters.

Two-phase olive mill waste (TPOMW, "alperujo") is a highly biotoxic sludge-like effluent of the olive-oil milling process with a huge seasonal production. One of the treatment approaches that has so far received little attention is the use of TPOMW as substrate for the cultivation of edible mushrooms. Fifteen fungal strains belonging to five species (Basidiomycota), that is, Agrocybe cylindracea, Pleurotus cystidiosus, P.

The effects of olives harvest period and production year on olive mill wastewater properties - evaluation of Pleurotus strains as bioindicators of the effluent's toxicity.

Olive mill wastewater (OMW) generated during the oil extraction from Olea europea L. var. koroneiki olives was sampled at the beginning, the middle and the end of the harvesting season for three successive crop production years, and from four olive mills.
