Sea buckthorn (Hippophae rhamnoides)-derived products have traditionally been used as food and medicinal ingredients in Eastern countries. The purpose of this study was to investigate the effect of oral intake of sea buckthorn oil products on tear secretion using a murine dry eye model. Orally administered sea buckthorn pulp oil (not seed oil) restored aqueous tear secretion to its normal value...

The 1990s witnessed a period of significant increase in investments in the oil and gas sector in Latin America. In most countries private investment took the lead after the privatization and liberalization of the sector. For example, in Argentina, Bolivia, Brazil, Ecuador, and Venezuela, private oil investment and/or some form of privatization made possible significant additions in hydrocarbons...

We estimate the effects of unexpected changes in oil prices on output for the case of Venezuela, an oil-exporting economy. Following Hamilton (2003), Lee et al. (1995), and Mork (1989), we estimate measures of oil shocks and determine the effect of these shocks on the Venezuelan economy. Our results suggest that oil shocks have had positive and significant effects on output growth in Venezuela ...

The rapid increasing the industrialization, motorization, in the world has remarkably raised the demand of the petroleum products. The reservations of such a petroleum based fuels are limited in the world. Furthermore, they are exhaustible and cost is rapidly increasing day to day. For those countries having not ability of petroleum recourses, are importing the petroleum fuels. So, it is quit n...

Growth studies show, counter to intuition, that the discovery of a natural resource may be a curse rather than a blessing since resource-rich countries grow slower than others. Moreover, resource abundance may involve a displacement of a growth-essential manufacturing sector, leading to Dutch Disease. Norway is an important exception to the curse and the disease. Since oil production started in...

This chapter provides a brief overview of issues related to understanding the origins and symptoms of the resource curse and the challenges triggered by oil dependency in the Arab World including the traditional issues related to economic diversification, Du...

This study employs the vector autoregressive model (VAR), impulse response function and variance decomposition to impact of oil price shocks on components government spending both oil-exporting importing countries over period from 1980 2018. While vast majority previous studies focused spending, this emphasized these current capital expenditure. It was found that affect expenditure positively i...

The extensive fluctuations in oil prices have vast impacts on economies. The economical instability may be observed for both oil-exporting and oil-importing countries due to high volatility of oil prices. Oil price data as a time series is a highly nonlinear system which exhibits complex patterns. Traditional oil time series analysis employs statistical methods to model and explain the oil data...
