abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
Life cycle assessment (LCA) was performed in dairy buffalo farms representative of Southern Italian farming systems, similar due to several characteristics, with the exception wheat production. This work evaluated impacts derived from this management choice, comparing crop (WWC) or not (NWC). In agreement literature, economic allocation chosen as a useful strategy attribute equivalents by-produ...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...

Ambitious fossil-free targets imposed on the aviation industry worldwide demand a large volumetric supply of sustainable fuel (SAF) to meet. Sweden's commitment 30% volume SAF blending target by 2030 attracts interest in local production. However, sustainability production is largely unknown. Addressing this gap, we aim explore potential technology pathways and assess their environmental perfor...
Effective project management requires reliable knowledge of cash required in different stages of project life cycle. Getting this knowledge is highly dependent on sophisticated consideration of project environment. Nature of projects and their environments are associated with uncertain conditions. In this paper, a new project cash flow assessment method based on project scheduling is proposed t...
Growing awareness of environmental sustainability in the agri-food sector has enhanced gradual shift toward less-impactful food and organic production systems.

The economic cultural importance attributed to Italian worldwide rep...
Solid waste is one of the unavoidable products of every society that necessitates the establishment of municipal solid waste management system. Because of variability in quantity and composition of municipal solid wastes, several management scenarios are considered. Assessing the environmental impacts of the life cycle of these scenarios will have a significant role in reducing and resolving ur...
The utilisation of waste biomass in biodiesel production as a sustainable energy source can lead to the incorporation circular bioeconomy principles current economic systems. Herein, we synthesised magnetically recyclable solid acid catalyst for esterification date seed oil. catalysts possessed superparamagnetic behaviour and high saturation magnetisation, allowing them be easily separated from...
