Although increasing numbers of research papers regarding biochar are being published worldwide, in some countries growing interest in biochar has only recently been observed; this is true of Poland. We analysed information on biochar research in Poland alongside lessons learned elsewhere in order to identify the significant opportunities and risks associated with biochar use. This data fed into a GIS-based multicriteria analysis to identify areas where biochar application could deliver greatest benefit. We found that 21.8% of agricultural land in Poland has at least moderate indication for biochar use (soil organic matter below 2% and ph below 5.5), while 1.5% was categorized as a priority as it also exhibited contamination. Potential barriers identified included biomass availability and associated risks of indirect land-use change due to possible national and transnational biomass production displacement. Biochar use could have positive global consequences as a climate change mitigation strategy, particularly relevant in a country with limited alternatives. Scaling up a mitigation technology that is viable on account of its co-benefits might be cost-effective, which could, in turn, adjust national perspectives and stronger involvement in developing mitigation policies at the regional level. Biochar has much promise in temperate conditions and further research should therefore be assigned to explore biochar’s environmental and socio-economic impacts.

The Coast Guard Yard in Curtis Bay·, MD implemented a PC/AutoCAD based CAD/CAM system and used it to construct a series of 15 M (49 foot) buoy tenders. Implementing CAD/CAM is primarily a management, rather than technical, challenge. Performance-Based Management Techniques were used to develop the new system as an integrated whole, controlled and documented under ISO 9001. The process was cost-effective, required minimum retraining, was fully implemented in a few months, and was appropriate to a small shipyard building boats, but extensible as required to medium sized ships. The authors discuss:The use of Performance-Based Management and team-building techniques to help implement the process;The use of process management techniques to document, control and systematically improve the process in order to remain competitive;The process developed, including methods to allow varying levels of operator skill, geometry, weight and interference control, and development of automation techniques;The lessons learned, the results in productivity improvement, and the future path for continuous improvement

Reliability Centered Maintenance

In new ship construction, maintenance planning affords both an opportunity and a challenge. On one hand, a new ship class enables maintenance planners to start with a clean slate and consider improved and more cost-effective maintenance methods. On the other hand, new manning concepts, lack of timely technical information when maintenance planning is conducted in parallel with detail design, use of equipment new to the fleet, and the like impose a measure of uncertainty on the planning process. In this paper, we review why and how Reliability-Centered Maintenance (RCM) techniques were applied to the new Polar icebreaker U.S. Coast Guard Cutter (CGC) Healy (frontispiece). We review how we incorporated condition-based maintenance techniques where appropriate. We discuss the decision process used for fine-tuning the Maintenance Procedure Cards (MPC) for CGC Healy's hull, mechanical, and electrical (HM&E) Preventive Maintenance Manual. Finally, we share some lessons learned in the process.

Access To Essential Medicines

In the less developed countries, most people do not have sufficient access to essential medicines. Generic medicines play an important role in increasing access to essential medical products, since they can be 20–90% cheaper than their branded equivalents. Generic medicines are therefore a key element to consider in many countries’ health policies and systems. The increasing global and regional demand for generics, driven by government policies and cost-effective strategies, create a significant opportunity for generic manufacturers around the world. This case study seeks to analyse the use of generic drugs in the Middle East and in so doing also unveil the nature of the generic drugs market in the Middle East, and specifically Iraq.

Faculty development programs are critical to the implementation and support of curriculum innovation. In this case study, the authors present lessons learned from ten years of experience in faculty development programs created to support innovation in technology enhanced learning. Stages of curriculum innovation are matched to stages of faculty development, and important lessons for success as well as current challenges are delineated and discussed.

Insight Into

Radical subject acceleration, or moving students through a subject area faster than is typical, including skipping grades, is a widely accepted approach to support students who are gifted and talented. This is done in order to match the student’s cognitive level and learning needs. This case study explored radical subject acceleration for gifted students by focusing on one school’s response to the learning needs of a ten year old mathematically gifted student. It provides insight into the challenges, accommodations and approach to radical subject acceleration in an Australian school. It explored the processes and decisions made to ensure that a gifted student’s learning needs were met and identified salient issues for radical subject acceleration. Lessons learned from this case study may be helpful for schools considering radical acceleration.

P Bioavailability

The bioavailability of phosphorus from different sources has been evaluated in the catchment area of the River Ilmenau (Lower-Saxony, Germany) by using algal assays. The P bioavailability describes the different potential of P from various sources of supporting eutrophication. Effluents from sewage treatment plants were highly bioavailable (72% of TP) whereas rainwater (26%) and erosion effluents (30%) showed a low bioavailability. In order to develop effective strategies to minimize P inputs into the river, source specific P bioavailability indices were determined and combined with a P balance to calculate inputs of vioavailable P (BAP) instead of total P (TP). It could be shown that the relative importance of the different P sources changes when applying BAP. Measures to reduce P inputs into the River Ilmenau will take P bioavailability into consideration and therefore lead to a more cost-effective management.
