Effective Human Reliability Analysis (HRA) requires both a qualitative analysis of potential human errors and a quantitative assessment of the likelihood of those errors. One of the main conclusions from an International HRA Empirical Study is the importance of qualitative analysis when performing HRA. Although qualitative data collection is relatively well established for HRA in the nuclear in...

Background: Petro-clival, clival and spheno-petro-clival tumours are still a neurosurgical challenge. Usually, the classical skull base transpetrous approaches are employed, although they are burdened by an important rate of morbidity, and a very low rate of radical removal is reported. Objectives: We present our indications and results with minimally invasive transnasal and transoral approache...

background petro-clival, clival and spheno-petro-clival tumours are still a neurosurgical challenge. usually, the classical skull base transpetrous approaches are employed, although they are burdened by an important rate of morbidity, and a very low rate of radical removal is reported. conclusions anterior transoral and transsphenoidal approaches are indicated for clival and spheno-petro-clival...

Reduction of fossil fuels sources, increasing of pollution gases emission, and global warming effects increase the demand of renewable fuels. One of the main candidates of alternative fuels is biodiesel. Biodiesel limits greenhouse gas effects due to the closed CO2 cycle. Biodiesel has more biodegradability, lower combustion emissions such as CO, SOx, HC, PM and lower toxicity than petro diesel...

Physicochemical properties of the commercially procured rubber seed oil (RSO) were studied to evaluate its potential as viable feedstock for biodiesel production. The procured rubber seed oil were characterized for acid value, saponification value, free fatty acid, flash point, kinematic viscosity, and refractive indices using standard methods. Results indicate that the procured rubber seed oil...

While the United States owns only three percent (3%) of the total world petro-oil reserves, it uses over twenty-five percent (25%) of its total global output on an annual basis. Furthermore, the US petro-oil consumption is expected to double by 2050. While the sources for US oil are innumerable, many of the countries which contribute vastly to the US oil supply are economically and politically ...
