Using the constituent elements of vulnerability, an evaluation index system for the ecological vulnerability of coastal areas under oil spill stress is established based on “Sensitivity–Adaptive Capacity-Exposure”. After selecting a gulf in China as the main case study in this work, the cluster analysis and reference method were applied in grading and value assigning for all indexes. In additio...

background: natural antioxidants with plant origin are incorporated to foods in the forms of essential oils or extracts. they can retard lipid oxidation and control spoilage bacteria in foodstuffs (e.g. meat products). objective: this work was aimed to evaluate the effect of nitrite partial replacement with mentha piperita essential oil (mpeo) on oxidative, microbial and sensory properties of c...

This study evaluated the occurrence of an enhancing inhibitory effect of the combined application of Origanum vulgare L. essential oil and acetic acid against Staphylococcus aureus by the determination of Fractional Inhibitory Concentration (FIC) index and kill-time assay in nutrient broth, meat broth and in a food model (meat pieces). Acetic acid showed MIC and MFC of 0.6 and 1.25 μL.mL(-1), r...

The paper presents the research results on electrostatic charging tendency (ECT) of transformer oil in a spinning disk system. The measurements were performed at different aging severity. Changes in static electrificationwere related to some classical aging indexes (conductivity, dissipation factor, water content, resistivity, etc.). Fast, inexpensive and reliable laboratory testing procedures ...

Diamondoids in crude oil are useful for assessing the maturity of oil in high maturation. However, they are very difficult to separate and accurately quantify by conventional geochemical methods due to their low abundance in oil. In this paper, we use comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC-TOFMS) to study the compounds in condensates from t...

Rainfall-runoff processes in a small oil palm catchment (8.2 ha) in Johor, Malaysia were examined. Storm hydrographs show rapid responses to rainfall with a short time to peak. The estimated initial hydrologic loss for the oil palm catchment is 5 mm. Despite the low initial loss, the catchment exhibits a high proportion of baseflow, approximately 54% of the total runoff. On an event basis, the ...

The main aim of this study was to evaluate the effect nut sizes and drying methods on sensory attributes hazelnut cultivars (Corylus avellana L. cvs. Çakıldak, Palaz Tombul) during storage. Shelled were dried under sun, shadow at room conditions cold 2 °C 7 stored 20±5 80±5 % relative humidity. Evaluation carried out quarterly (harvest, 3, 6, 9 months). In Çakıldak cultivar (in 16 mm size), odo...

The content of fatty acids as well as the ratio between unsaturated and saturated fatty acids is important parameter for determination of nutritional value of certain oil. Therefore the newest trend in food processing industry is notifying the composition of edible oils and other food commodities for the content of each individual fatty acid. The main objective of this work was to identify the ...
