An Autonomous Telescope Implementation at the USQ Mount
An Autonomous Telescope Implementation at the USQ Mount Kent Observatory A Dissertation submitted by Scott Sinclair, BSc For the award of Master of Science University of Southern Queensland Faculty of Sciences February, 2010. ii Abstract Over the past decade, the quality and sophistication of optical telescopes commercially available has dramatically increased, with instruments in a class previously only within the reach of professional facilities now commonly possessed by advanced amateurs. A corresponding reduction in cost not only for these optical assemblies, but also for ancillary equipment such as high quality mounts, CCD cameras and computer hardware and software has meant that many areas of research, and in particular those appropriate for high school and university students, are now far more accessible than before, vastly increasing interest in the study of astronomy and astrophysics. At the same time, there has occurred a rapid expansion of the Internet, measurable in terms of its pervasiveness, richness of end-user experience and quality of infrastructure. The combination of these phenomena has meant that most of the issues that have stymied the development of remote and robotic observation have now been largely overcome. Since early 2004, the author and co-contributors from the University of Southern Queensland’s Faculty of Sciences have been developing a system for remote and robotic observation at the Mt Kent Observatory site near Toowoomba in South East Queensland, Australia. Reliable, online access to an observatory is provided, with students being able to conduct scientific-grade photometric and astrometric research using a system built primarily of commercial, off-the-shelf components. -
An Alternative to Conventional Rock Fragmentation Methods Using SCDA: a Review

Under such circumstances, the continuation of existing methods in rock fragmentation in such applications is questionable due to the proven adverse environmental impacts associated with them. In this regard; the possibility of using more environmentally friendly options as Soundless Chemical Demolition Agents (SCDAs) play a vital role in replacing harmful conventional rock fragmentation techniques for gas; oil and mineral recovery. This study reviews up to date research on soundless cracking demolition agent (SCDA) application on rock fracturing including its limitations and strengths, possible applications in the petroleum industry and the possibility of using existing rock fragmentation models for SCDA-based rock fragmentation; also known as fracking. Though the expansive properties of SCDAs are currently used in some demolition works, the poor usage guidelines available reflect the insufficient research carried out on its material’s behavior. -

However, an effective fracturing process requires a precise understanding of a formation’s in-situ strength behavior, which is mainly dependent on the formation’s in-situ stresses and fluid saturation. The aim of this study is to identify the effect of brine saturation (concentration and degree of saturation (DOS)) on the mechanical properties of one of the common unconventional reservoir rock types, siltstone. Most common type of non-destructive test: acoustic emission (AE) was used in conjunction with the destructive tests to investigate the rock properties. Unconfined compressive strength (UCS) and splitting tensile strength (STS) experiments were carried out for 78 varyingly saturated specimens utilizing ARAMIS (non-contact and material independent measuring system) and acoustic emission systems to determine the fracture propagation. -

Fifty five USQ student-athletes from Toowoomba, Ipswich, Springfield and online are representing the University on the Gold Coast from September 24-29. Miss Hollis-Neath will roll out for the USQ lawn bowls team, and said it was an honour to be appointed co-captain alongside Christopher Watson. “This will be the fourth time I have represented USQ since I started as a student in 2015, and my second time competing at the Australian Uni Games,” she said. “Some of my favourite university memories were made at the Uni Games and to be named co-captain is an amazing honour Crystal Hollis-Neath leads the USQ team at this year’s Australian Uni Games. and something I am very grateful to have received. “I take a lot of pride in wearing the USQ uniform and as soon as I get on the green, I will be giving it my best shot.” Miss Hollis-Neath, who lives in the small town of Nobby, discovered her interest for bowls when her grandfather Eugene CLIFTON used to take her to play every Wednesday night. -

Comparison of CO2 Flow Behavior Through Intact Siltstone Sample Under Tri-Axial Steady-State and Transient Flow Conditions
applied sciences Article Comparison of CO2 Flow Behavior through Intact Siltstone Sample under Tri-Axial Steady-State and Transient Flow Conditions Chengpeng Zhang 1 ID , Ranjith Pathegama Gamage 1,* ID and Mandadige Samintha Anne Perera 2 ID 1 Deep Earth Energy Laboratory, Department of Civil Engineering, Monash University, Building 60, Melbourne, VIC 3800, Australia; [email protected] 2 Department of Infrastructure Engineering, The University of Melbourne, 209B, Building 175, Melbourne, VIC 3010, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-3-9905-4982 Received: 20 March 2018; Accepted: 27 June 2018; Published: 5 July 2018 Abstract: With its low viscosity properties, CO2 has much greater penetration capacity into micro-fractures, and therefore has more potential to create expanded and effective fractures in shales during the hydraulic fracturing process. However, the feasibility of this technique is dependent on the accurate prediction of formation flow characteristics, given the high leak-off of CO2 at deep depths. The aim of this study is therefore to understand the flow behavior of CO2 in deep shale plays. A series of tri-axial permeability tests was conducted under both steady-state and transient conditions. The test results show much lower permeability values for liquid CO2 than gaseous CO2, and the permeability under transient conditions is much lower than that under steady-state conditions, due to the combined effects of the reduced slip-flow effect under low pressures and the temperature variation influence under steady-state conditions. Under steady-state conditions, unstable flow behavior occurred at higher injection pressure (≥9 MPa) possibly due to the fine mineral particle migration and the deposition of small drikold particles, which indicates the serious error in permeability calculation under steady-state conditions. -

Characteristics of Clay-Abundant Shale Formations: Use of CO2 For
Review Characteristics of Clay‐Abundant Shale Formations: Use of CO2 for Production Enhancement Chengpeng Zhang 1, Ranjith Pathegama Gamage 1,*, Mandadige Samintha Anna Perera 2 and Jian Zhao 1 1 Deep Earth Energy Laboratory, Department of Civil Engineering, Monash University, Building 60, Melbourne, VIC 3800, Australia; [email protected] (C.P.Z.); [email protected] (J.Z.) 2 Department of Infrastructure Engineering, The University of Melbourne, Building 176, Parkville, VIC 3010, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61‐3‐9905‐4982 Received: 12 October 2017; Accepted: 9 November 2017; Published: 16 November 2017 Abstract: Clay‐abundant shale formations are quite common worldwide shale plays. This particular type of shale play has unique physico‐chemical characteristics and therefore responds uniquely to the gas storage and production process. Clay minerals have huge surface areas due to prevailing laminated structures, and the deficiency in positive charges in the combination of tetrahedral and octahedral sheets in clay minerals produces strong cation exchange capacities (CECs), all of which factors create huge gas storage capacity in clay‐abundant shale formations. However, the existence of large amounts of tiny clay particles separates the contacts between quartz particles, weakening the shale formation and enhancing its ductile properties. Furthermore, clay minerals’ strong affinity for water causes clay‐abundant shale formations to have large water contents and therefore reduced gas storage capacities. Clay‐water interactions also create significant swelling in shale formations. All of these facts reduce the productivity of these formations. The critical influences of clay mineral‐ water interaction on the productivity of this particular type of shale plays indicates the inappropriateness of using traditional types of water‐based fracturing fluids for production enhancement.
