The research aims to assess the relationships between the crash rates and road consistency. Design consistency assessment is a tool employed by designers to improve road safety. The case study involved a rural two-lane two-way road in Southern Italy located on a flat terrain without spiral transition curves between tangent segments and circular curves. Road alignment consistency was examined in two steps: by adopting standards in force in Italy based on the design speed profile and by plotting operating speed profile to determine the area bounded by the speed profile and the average weighted speed, and the standard deviation of operating speeds for each geometric segment. Operating speed prediction model, which returns the 85th percentile of the speed distribution of the only cars under free flow conditions, right weather conditions, and lighting was adopted. A negative exponential function was performed to predict the global consistency of a road as a whole. Finally, a model for predicting the crash rate was calibrated, confirming an increase of design consistency when the crash rates decrease significantly. The consistency model represents a useful tool during the geometric design process or the evaluation process for two-lane rural highways.

This paper reviews progress made over the last decade with the shrinking object approach to the kinetics of batch dissolution. It demonstrates how the O’Connor–Greenberg equation leads to three dissolutions: those that remain well undersaturated, those that saturate with a great excess of solid left-over, and those in the middle ground where saturation is approached or attained, but where much of the solid originally added dissolves. The equations that describe these conditions are discussed, alongside sample results that validate their use with test substances, for example, salts, sucrose, silica gel, and gypsum. The equations are then shown to be consistent with the hydrodynamic approach to dissolution. Finally, further work with middle-ground dissolutions of gypsum lead to a mechanism for the back-reaction, which involves the CaSO40 ion-pair. After comparison with existing studies of calcium carbonate dissolution, it is argued that this is a universal mechanism for salt dissolutions. The work improves batch dissolution as a technique to the point where it can be used synergistically with chemo-stat and rotating disc approaches. Suggestions are made for greater standardization in dissolution conditions, especially in environmental work where the data collected has to have global consistency.

The reverberations of Wall Street had to be felt across the global banking system. Last September, the world economy seemed to be hurtling down in a way that had initially raised the spectre of the Great Depression in America of the late 1920s. This is based largely on the performance of stock markets which are supposed to reflect future trends in the real economy. However, such knowledge embedded in the markets can be imperfect, as we have learnt by now. In some ways, the global financial crisis and its fallout are forcing economic agents to acquire new knowledge in regard to what might happen in the future. It was difficult to explain rationally why the stock markets were furiously running up even as company balance sheets were still bleeding. A few years ago, International Financial Reporting Standards (IFRS) were a distant possibility. Today, the reality is far different. We are in a dramatic shift that is fast making IFRS the most widely accepted accounting model in the world. As the business environment becomes increasingly global and companies routinely list on stock exchanges in many countries, the need for consistent worldwide reporting standards intensifies. IFRS clearly addresses this issue; its goal is to create comparable, reliable, and transparent financial statements that will facilitate greater cross-border capital raising, trade and better corporate governance practices. Thus acceptance of IFRS is gaining momentum across the globe. IFRS transition program for any organization will have multi – dimensional effect because of differences which exist between IFRS and Local GAAPs. The objectives of the paper is to highlight the nature of such differences with examples along with analysing the provisions of IFRS, comparative analysis of IFRS with Indian GAAP system, benefits, and major issues in first time adoption of IFRS in Indian companies with the help of case study of Indian corporate.
