  • Oliver Sacks: the patient-focused polymath

    A man sits on a stage and begins to speak. He is humble and soft spoken; he talks tenderly about a patient of his – an elderly lady in a home who had started to hallucinate. He recalls the story of how he diagnosed her, smiling as he retells the lady’s jokes and remembers how happy she was to ...

  • Effect of recycled water applied by surface and subsurface irrigation on the growth, photosynthetic indices and nutrient content of young olive trees in central Iran

    Water shortage has encouraged the quest for alternative sources of water for food production and agricultural development. Recycled water (RW) is one of the most available water resources with great potential for use in farm irrigation. This experiment was carried out to investigate the use of RW as the irrigation source and its application method, subsurface leaky irrigation (SLI) system or ...

  • Innovative method for recovery and valorization of hydroxytyrosol from olive mill wastewaters

    The nutritional properties of olive oil can be attributed to its oleic acid and phenolic compounds content, acting as natural oxidants to prevent human diseases. In particular, hydroxytyrosol has an anti-inflammatory action similar to omega 3 fatty acids from fish oil. The olive oil production was conducted by two extraction procedures: first, a two-phase extraction giving extra-virgin olive ...

  • Soil and water: towards a larger-scale perspective of their relations

    Land use changes over time have altered relations between soils and water cycles throughout Europe. There are regions where forests were cut for agriculture or herding, or for industrial, mining, and/or railroad use. Soils were lost, through mud floods, and the water cycles changed so that their present status is one of badlands and/or desert-like areas. Early stages in the path to degradation ...

  • Comparative study of isotherm parameters of lead biosorption by two wastes of olive-oil production

    Batch isotherm studies were carried out on a laboratory scale: (i) to investigate the effectiveness to remove lead of two wastes (olive stone (OS) and olive tree pruning (OTP)), untreated and chemically treated; and (ii) to examine the applicability of various adsorption isotherms to fit the experimental data. Results from tests were analyzed using seven equilibrium isotherm correlations ...

  • Mixed micelles-mediated dephenolisation of table olive processing's wastewaters

    Olive processing wastewaters account for highly pollutant agro-industrial effluents. Their phenolic compounds are responsible for their toxicity. Those natural compounds have to be degraded or recovered before any discharge into the environment. This investigation deals with the extraction and concentration of the phenolic compounds into an aqueous phase using a mixture of nonionic/anionic ...

  • Improved recoveries and lower background for the analysis of PAHs in Olive Oil

    Using Supelclean EZ-POP NP and an SLB-5ms GC Column A recent survey implemented by Supelco revealed that 58% of analytical chemists in the food industry find the analysis of compounds in fatty matrices to be highly problematic. Lipid interferences can produce elevated detection limits, contamination of LC and GC systems, and ultimately decrease instrument and column lifetime. ...

  • Chemical and biological properties of a sandy loam soil amended with olive mill waste, solid or liquid form, in vitro

    The profitable use of the large amounts of olive oil mill wastes produced in Greece, as source of soil organic matter, might be probably beneficial to soil microorganism activity. A high rate of organic matter biodegradation was observed in soil samples amended with the liquid form of olive mill wastewater, whereas the vice versa results were obtained with the solid form. When the soil ...

  • Review: Effects of olive mill wastewater application on soil properties and plants growth

    Comparative effects of untreated olive mill wastewater (UOMW), treated olive mill wastewater (TOMW) and bioaugmented olive mill wastewater (BOMW) on soil properties, on seeds germination and on plants growth were investigated. The water holding capacity, the salinity, the organic carbon content, humus, total nitrogen, phosphate and potassium increased when the spread amounts of UOMW (50, 100 and ...

  • Olive Processing

    Problem: The aerated ponds were producing a foul odor & the chloride content of the aquifer was increasing to a level endangering the water quality. Solution: A Hydrocal CAF system is installed to treat the pit water only. This stream, which aligns the olives to be pitted, is highly contaminated with oil, grease, and ruptured olive tissue. The separate ...

  • Argan oil: Too much of a good thing?

    Most people have heard of the health benefits of using olive oil instead of butter or other saturated animal fats. The monounsaturated fats in olive oil have been shown to reduce levels of harmful cholesterol, and as a result nutrition experts have touted it and other aspects of the Mediterranean Diet as heart healthy. But olive oil ...

  • Jojoba: A Potential Desert Oil Crop

    Jojoba (Simmondsia chinensis usually grows to a height of 1-2m and may reach heights of three meters or more under ideal growing conditions. S. chinensis has a normal life span of at least 100 years and may live more than 200 years. Pollination is via wind or insects. The fruit is a green capsule enclosing as many three seeds. When ripe (3-6 months after fertilization) the capsule splits and ...

  • Comparison of ISO 9613-2 vs Advanced Calculation Methods using Olive Tree Lab - Terrain

    Abstract The process of performing an Environmental Impact Assessment includes the study of noise propagation. Often, the path from a noise source to a noise sensitive location involves complicated mechanisms of sound transmission. These mechanisms may relate to diffraction & reflections from obstacles (natural or man made), ground properties, and meteorological conditions. The ...

  • Fertilizer NPK from human urine and olive oil mill wastewaters

    The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two ...

  • Exergoeconomic analysis of an olive oil refining plant

    This study deals with evaluating the performance of an olive oil refinery plant installed in Izmir, Turkey, using Exergy, Cost, Energy and Mass (EXCEM) method, which is based on the real operational data and costs of the equipments. The most efficient equipment is obtained to be the shell and tube type heat exchanger with an exergy efficiency value of 85.8% at 25°C, ranging from 86.2% to 85% for ...

  • Olive oil Mill Wastewater properties change during infiltration through clay soils

    Olive oil Mill Wastewaters (OMW), are stored in clay basins in the region of Sfax (Tunisia). Field permeability measurements showed that the clay is not completely impermeable and its structure can be modified by the infiltration of OMW. Analysis of chemical composition of soil revealed the presence of phenolic compounds resulting from the percolation of OMW. An infiltration filled with clay and ...

  • Modeling olive crop yield in andalusia, spain

    Andalusia (southern Spain) is the largest olive (Olea europaea L.) oil producing region in the world. This study sought to identify the main factors influencing olive fruit production in this region, by modeling pollen release as an index of flowering intensity, field floral phenology data, and meteorological data over the fruiting season in three main olive-producing provinces of Andalusia: ...

  • `EU Policies for Olive Farming: Towards Sustainanble Production in Europe` by WWF&Birdlife International, supported by the EEB and FoEE

    Since the 1990s, BirdLife International and WWF, the global conservation organisation, have been voicing concern over the environmentally damaging trends in European olive farming, and calling for fundamental changes to the CAP market regime governing the sector. In 2001, a report was published, setting out the main environmental issues, and making detailed proposals for a complete reform of the ...
