The correlation between health and wealth is arguably a very solidly established relationship. Yet that relationship may be reversing. Falling oil prices have raised (average) per capita incomes, worldwide. But from a long-run perspective they are a public health disaster. The latter is easy to see: low oil reduces the incentive to develop alternative energy sources and "bend the curve" of glob...

This paper investigates the valuation and hedging of spread options on two commodity prices which in the long run are cointegrated. For long term option pricing the spread between the two prices should therefore be modelled directly. This approach offers significant advantages relative to the traditional multi-factor spread option pricing model since the correlation between two asset returns is...

Relationship among malondialdehyde (MDA), 2-thiobarbituric acid (TBA)-reactive substances (TBA-RS), and tocopherols in the oxidation of rapeseed oil was investigated. MDA was determined by a new HPLC method with chemical derivatization. When the oil was heated at 170 degrees C, TBA-RS and MDA increased. The contents of TBA-RS were approximately 1.6 times higher than those of MDA. Correlation be...

The chemical composition of the hips essential oils of 9 taxa of Rosa L. was analyzed and compared using the standardized analytical GC and GC/MS methods. The volatile hips oil compositions for these species are presented. All oil samples were dominated by following components: vitispiran (isomer), a-E-acaridial, dodecanoic acid, hexadecanoic acid, docosane (C22), beta-ionone, 6-methyl-5-hepten...

this study was conducted to determine the effect of foliar salicylic acid (sa) and citric acid (ca) applications on growth, biochemical characteristics and essential oil content of thyme (thymus vulgaris l.) grown under field conditions. salicylic acid (0.5 and 1 mm) and citric acid (5 and 10 mm) were applied three times during the vegetation at 15 day intervals. results revealed that foliar ap...

background: fatty acids are the main compounds in edible oils. oil thermal stability depends on the composition of fatty acids. so, this study was conducted to investigate the effect of fatty acid composition on the oxidative stability of extra virgin olive oil during heating process.  methods: totally, eight virgin olive oil samples, including five imported oils from market place of mahabad an...

This paper focuses on oil as a key determinant in US-GCC stock market interdependence. The analysis uses monthly data over the period from January 2003 to December 2019. interdependence between US and GCC is established using Asymmetric Dynamic Conditional Correlation model. We then investigate impact of both range macroeconomic variables nature correlation. Our results find that returns volati...

To investigate the influence of different dietary fats on lipids and anti-cardiolipin antibody levels, autoimmune NZB/W F1 mice were fed on diets containing 200 g dietary fat as palm oil, lard-soyabean oil (1:1, w/w), soyabean oil, rapeseed oil or fish oil/kg. In addition, each dietary fat group was divided into an early-feeding group with feeding from 2 months of age, and a late-feeding group ...

Using dissipative particle dynamics (DPD), we model the interfacial adsorption of pH-responsive polyelectrolytes and polyelectrolyte-grafted nanoparticles (PNPs) at a planar water-oil interface. The electrostatic interactions in the presence of the dielectric discontinuity across the interface are modeled by exploiting the Groot method, which uses an iterative method to solve the Poisson equati...

This paper examines the determinants of foreign direct investment (FDI) in Iran by applying the structural equation modelling (SEM). Using the annual time series data for the 1991-2006 period, two models were developed. In the first model the correlation between 12 determining factors and FDI in Iran were analyzed and in the second model the 12 factors were fit into five categories of determina...
