Main Factor

Environmental magnetism techniques enable us to reconstruct paleoclimate conditions in some deposition such as losses. The  magnetic properties  of  minerals  are  used  as  proxies  for  environmental  changes. For this study, loess/paleosol sequence of Kolet section at Neka, north-east of Iran were magnetically investigated. We applied environmental magnetism methods, to reconstruct paleoclimate changes. We investigated relationship between paleoclimate changes and environmental magnetism proxies like magnetic susceptibility (?) variation. The laboratory techniques indicated the presence of main factor of magnetic property in loess/paleosol sequence, such as magnetite, maghemite and etc. We also estimated magnetically parameters (like SIRM, HIRM and etc.) to confirm concentrations of both aeolian and pedogenic particles versus variations of magnetic susceptibility enhancement. The ? values show prominent peaks for the three well developed soil and paleosol horizons, Recent Soil (S0), Upper Paleosol (S1) and Lower Paleosol (S2); which refer to warmer and wetter conditions. As result, we concluded that the increase/decreasing of magnetic susceptibility is coinciding with palaeosol/loess sequence, and probably with humid/arid conditions. Moreover, variations of magnetic susceptibility versus lithological column of Kolet section enabled us to recognize paleoclimatically periods known as interglacial/glacial cycles. The obtained  magnetic  data  indicate  that  during over  the  past  50  ka,  there  have  been  at  least  two glacial/interglacial periods and since last 20 ka, there was no main glaciation occurrence, in the study area.

Abstract In the present research, SPT results are adopted to establish relationships for estimation of the relative density in a sandy soil. SPTs are performed in 20 boreholes in Astaneh-ye Ashrafiyeh city in Iran. Laboratory tests including mineralogy, relative density, soil gradation, Atterberg limits, and unit weight were performed on the soil samples. The SPT numbers were then properly corrected. In particular, the correct procedure for correction of the SPT number against the existing overburden effective stress is discussed when the SPT is performed in the vadose zone where the soil may be unsaturated. The soil in the study area is dominantly classified as SP-SM. The relationship between the relative density as one of the most important parameters for dominantly granular soils, with the corrected SPT number (N 1(60) ) and fines content is then investigated and discussed using artificial neural network and statistical analysis. Results showed that for the soil of interest, the developed relationship performs better than those established in the literature, hence demonstrating the value of developing locally tuned relationships for important projects.

Scottish History

Hugh Trevor-Roper (Lord Dacre) made several iconoclastic interventions in the field of Scottish history. These earned him a notoriety in Scottish circles which, while not undeserved, has led to the reductive dismissal of Trevor-Roper's ideas, particularly his controversial interpretation of the Scottish Enlightenment, as the product of Scotophobia. In their indignation Scottish historians have missed the wider issues which prompted Trevor-Roper's investigation of the Scottish Enlightenment as a fascinating case study in European cultural history. Notably, Trevor-Roper used the example of Scotland to challenge Weberian-inspired notions of Puritan progressivism, arguing instead that the Arminian culture of north-east Scotland had played a disproportionate role in the rise of the Scottish Enlightenment. Indeed, working on the assumption that the essence of Enlightenment was its assault on clerical bigotry, Trevor-Roper sought the roots of the Scottish Enlightenment in Jacobitism, the counter-cultural alternative to post-1690 Scotland's Calvinist Kirk establishment. Though easily misconstrued as a dogmatic conservative, Trevor-Roper flirted with Marxisant sociology, not least in his account of the social underpinnings of the Scottish Enlightenment. Trevor-Roper argued that it was the rapidity of eighteenth-century Scotland's social and economic transformation which had produced in one generation a remarkable body of political economy conceptualising social change, and in the next a romantic movement whose powers of nostalgic enchantment were felt across the breadth of Europe.

The Financial Master Plan (2001- 2010) aims to enhance the capacity of banking industry so that higher effic iency and productivity can be reaped in the future. This study seeks to determine the impact of merger on the efficiency and productivity ofcommercial banks in Malaysia for the period 1995 until 2005. The study uses a non-parametric approach, nam ely DEA (data envelopment analysis?) to estimate the efficiency scores and to construct the Malmquist productivity index. To enable this estimation, three bank inputs and outputs are used. Amongst the findings are those banks exhibit higher efficiency score after the merger and thefo reign banks are more efficient than the local banks. Productivity of the banks is calculated in both periods, before and after the merger: The results show that, it is the local banks that have improved the most after the merger. The main source of productivity is technical change or innovation. The findings support the existing policy of having larger domestic banks in term of size.

Purpose – The purpose of this paper is to suggest the usage of the project finance (PF) scheme as a suitable mechanism to fund energy efficiency projects at the urban scale and present its advantages and adoption barriers. Design/methodology/approach – A case study is developed to renew the traffic lighting system of an Italian town via replacement of the old lamps with new light-emitting diode (LED) technology. Several partners are involved in the case project to construct a viable PF arrangement. Findings – The case study presents the viability of the proposed PF scheme that provides for acceptable financial returns and bankability. However, it also shows that the need for short concession periods may call for a public contribution to the initial funding to make the project more attractive to private investors. Practical implications – This case study is a useful guideline for governments and promoters to using the PF arrangement to fund energy efficiency investments in urban settings. It helps designing an appropriate PF scheme and understanding the advantages of PF to reduce risk and, consequently, increase the debt leverage and profitability of energy efficiency projects. Originality/value – This paper contributes to bridging the gap about the lack of works addressing the implementation of the PF mechanism in the energy efficiency sector in urban areas. The importance of this paper is also associated with the shortage of traditional public finance faced by many cities that forces to seek for alternate forms of financing.
