The mining industry worldwide has recognized in the past the need to apply specific rules and guidelines in the reporting of mineral resources and reserves. The high financial investment and risk associated with any mining project and the ever stricter environmental and social controls were the forces behind this recognition. For years the industry experienced the development and enforcement of...

The Unified Model (UM) code supports simulation of weather, climate and earth system processes. It is primarily developed by the UK Met Office, but in recent years a wider community of users and developers have grown around the code. Here we present results from the optimisation work carried out by the UK National Centre for Atmospheric Science (NCAS) for a high resolution configuration (N512 ≈...

Software libraries typically represent substantive investment into a single code base, often capturing the best-known practices, algorithms, and data structures for a given problem domain. Popular libraries become more than a collection of code; they become a language in which programs and algorithms can be expressed. Just as a parallelizing compiler can take program code written in a general-p...

Bar coding for the medication administration step of the drug-use process is discussed. FDA will propose a rule in 2003 that would require bar-code labels on all human drugs and biologicals. Even with an FDA mandate, manufacturer procrastination and possible shifts in product availability are likely to slow progress. Such delays should not preclude health systems from adopting bar-code-enabled ...

China’s increased trade with and investment in Africa has boosted the continent’s growth rate but has also generated considerable controversy. In this paper we investigate China’s outward direct investment (ODI) in Africa using macro and micro data. The aggregate data on China’s ODI in African countries reveal that China’s share of the stock of foreign investment is small, though growing rapidl...

This thesis consists of three essays that examine the impact of tax policy on firms’ decisions to invest in productive capital. The first chapter uses newly-collected data on transaction prices of used construction machinery to examine the impact and incidence of recent tax incentives for investment. Theory predicts that incentives applying only to new investment should drive a wedge equal to t...

An evaluation of the current status of two novel clusters, running Linux and NT, has been made to assess their performance for parallel CFD calculations. The core algorithm of the code is the conjugate gradient method used to solve the pressure equation. For good performance, a low latency and high bandwidth is required and the results indicate that, without substantial investment in this area,...

among investments in different sections of economy, investment in agriculture is great importance. in addition to increasing production and job opportunities in agriculture, investment in this section will help to increase these in other sections as well, due to back and front relations with other economic activities. due to the fact that investment does not yield rapidly, and it takes some tim...
