The typical underground mining development and reconciliation process across the world utilises the common design, construct, verify and rework methodology. The primary focus of a mining development contractor is to meet the required development schedule. Hence, the development cycle is often designed and optimised to reduce the cycle time and increase the advance rate. The reconciliation of development headings is time consuming, and often a manually intensive process of verifying the installation against design via survey. Hence, this is often left as a secondary task with long delays between any feedback to the development crews. Leveraging the latest in artificial intelligence technology, high density LiDAR and high speed computing systems can provide the ability for development crews to receive real-time in-cycle feedback on their ground support construction and also to monitor the effectiveness of the ground support. This has potential to significantly increase the efficiency and quality of reinforcement, whilst reducing wastage in development.

Mushrooms and mushroom extracts have traditionally been used as therapies for a wide variety of ailments, including allergy, arthritis, and other inflammatory disorders. However, more evidence is required on the mechanism by which mushrooms exert these effects. In the present study, the anti-inflammatory properties of ethanol and hot water extracts prepared from 27 fungal samples collected between October and November 2011 at various forest locations in the southwest of Ireland were investigated using the lipopolysaccharide (LPS)-stimulated mouse macrophage (RAW264.7 cells) model of inflammation. LPS-stimulated cells were incubated in the presence of mushroom extracts at nontoxic concentrations for 24 h and the production of interleukin-6 (IL-6) was quantified by ELISA. Seven ethanolic and one hot water extract that decreased IL-6 production were selected for further study. The extracts were then incubated with LPS-stimulated cells for 24 h and the production of IL-6, tumor necrosis factor-alpha (TNF-α), and nitric oxide (NO) was measured. Ethanolic extracts prepared from Russula mairei, Lactarius blennius, Craterellus tubaeformis, Russula fellea, and Craterellus cornucopioides demonstrated selective anti-inflammatory activity by decreasing the production of NO and IL-6 but not TNF-α in LPS-stimulated RAW264.7 cells. These findings support existing evidence of the anti-inflammatory potential of mushroom extracts.

The Students Understanding eNergy (SUN) Project reports significant long-term effects on biology teacher knowledge and self-efficacy regarding biological energy transfer. Teachers use a hydrogen fuel cell and manipulatives to develop a model of energy transfer based on electrons moving in thermodynamically spontaneous reactions., Biological energy flow has been notoriously difficult to teach. Our approach to this topic relies on abiotic and biotic examples of the energy released by moving electrons in thermodynamically spontaneous reactions. A series of analogical model-building experiences was supported with common language and representations including manipulatives. These materials were designed to help learners understand why electrons move in a hydrogen explosion and hydrogen fuel cell, so they could ultimately understand the rationale for energy transfer in the mitochondrion and the chloroplast. High school biology teachers attended a 2-wk Students Understanding eNergy (SUN) workshop during a randomized controlled trial. These treatment group teachers then took hydrogen fuel cells, manipulatives, and other materials into their regular biology classrooms. In this paper, we report significant gains in teacher knowledge and self-efficacy regarding biological energy transfer in the treatment group versus randomized controls. Significant effects on treatment group teacher knowledge and self-efficacy were found not only post–SUN workshop but even 1 yr later. Teacher knowledge was measured with both a multiple-choice exam and a drawing with a written explanation. Teacher confidence in their ability to teach biological energy transfer was measured by a modified form of the Science Teaching Efficacy Belief Instrument, In-Service A. Professional development implications regarding this topic are discussed.

I’ve been a Mac OS X developer for several years. But I’m always looking for something new and interesting, so when the iPhone SDK was announced in March 2008, I jumped at the opportunity.

As the fourth book in our series of iPhone Projects based on the work and experiences of iPhone, this volume takes on the more advanced aspects of iPhone development. The first generation of iPhone applications has hit the App Store, and now it's time to optimize performance, streamline the user interface, and make every successful iPhone app just that much more sophisticated. Paired with Apress's bestselling Beginning iPhone Development: Exploring the iPhone SDK, you'll have everything you need to create the next great iPhone app that everyone is talking about. Optimize performance. Streamline your user interface. Do things with your iPhone app that other developers haven't attempted. Along with Series Editor Dave Mark, your guides for this exploration of the next level of iPhone development, include: Ben Panda Smith, discussing particle systems using OpenGL ES Joachim Bondo , demonstrating his implementation of correspondence gaming in the most recent version of his chess application, Deep Green. Tom Harrington implementing streaming audio with Core Audio, one of many iPhone OS 3 APIs. Owen Goss debugging those pesky errors in your iPhone code with an eye toward achieving professional-strength results. Dylan Bruzenak building a data-driven application with SQLite. Ray Kiddy illustrating the full application development life cycle with Core Data. Steve Finkelstein marrying an offline eMail client to Core Data. Peter Honeder and Florian Pflug tackling the challenges of networked applications in WiFi environments. Jonathan Saggau improving interface responsiveness with some of his personal tips and tricks, including blocks and other esoteric techniques. Joe Pezzillo pushing the frontiers of APNS, the new in iPhone OS 3 Apple Push Notification Service that makes the Cloud the limit for iPhone apps. Noel Llopis taking mere programmers into a really advanced developmental adventure into the world of Environment Mapping with OpenGL ES. What you'll learn Use wi-fi to do more than simply connect to the Internet. Communicate with other iPhone users in real time. Take advantage of all the tricks built into Cocoa Touch. Convert your iPhone and iPod touch apps for use in other environments. Convert your other mobile apps for use with iPhone and iPod touch. Who is this book for? All iPhone application developers with any level of experience or coming from any development platform, though this title is the natural choice after any of the other iPhone X Projects books.
