Transient absorption spectroscopy with sub-100 fs time resolution was performed to investigate the oligomerisation behaviour of eYFP in solution. A single time constant tau(AD)=2.2+/-0.15 ps is sufficient to describe the time-resolved anisotropy decay up to at least 200 ps. The close contact of two protein barrels is deduced as the exclusive aggregation state in solution. From the final anisotr...

Energy consumption cost and environmental effect are dynamic challenge to cloud computing. Data centers are the backbone of cloud computing. They continue to be challenging problems to energy efficiency. We investigated previous research based on energy efficiency approach and obtained the conditions to facilitate green cloud computing. Reducing energy consumption and emissions of carbon dioxid...

This paper presents the current scenario of energy availability in a typical rural telecom system and proposes green energy utilization in rural telecom sector in India. The paper discusses the renewable energy source as the best alternative for rural telecom to supply the required load at any given time. The technical suitability and financial viability of using green energy sources to meet en...

The energy issue has given rise to a prolific research field, which branches into several strands. One of these strands focuses on the role played by building features in shaping property prices. Indeed, market players are expected show higher willingness pay for units characterized performance. study so-called price premium efficiency flourished last decade or so; plenty evidence is now availa...

We develop a model of premium sharing for firms that offer multiple insurance plans. We assume that firms offer one low quality plan and one high quality plan. Under the assumption of wage rigidities we found that the employee's contribution to each plan is an increasing function of that plan's premium. The effect of the other plan's premium is ambiguous. We test our hypothesis using data from ...

Automobile hull insurance has attracted much attention due to the high rate of vehicle applications in daily lives. Since purchasing these policies is optional in Iran and their premium rates are set competitively, a competition is formed among the insurance companies for attracting low risk drivers. However, most of the insurers still use comparative rates and pay no or less attention to the f...

A central issue for the Algerian city, in dry environment, is awareness of establishment and preservation particular green spaces within framework sustainability. The overall goal this study to concentrate on issues space provision city Boussaada. Boussaada a complex fragile with rich history, archeological natural diversity, under tremendous anthropogenic stress. has long had availability area...

In this introductory paper for the Theme Issue on green tribology, we discuss the concept of green tribology and its relation to other areas of tribology as well as other 'green' disciplines, namely, green engineering and green chemistry. We formulate the 12 principles of green tribology: the minimization of (i) friction and (ii) wear, (iii) the reduction or complete elimination of lubrication,...
