Sports engineering uses mathematics and physics to develop solutions to sporting problems. It involves the design and manufacture of sports equipment and facilities that can help maximise athletic performance. In order to develop fit-for-purpose products, it is necessary to consider the motions and movements of athletes. Professor Shinobu Sakai, Production Systems Engineering and Sciences, Komatsu University, Japan, is combining AI and neural networks (NN) to develop multifunctional and high-performance sports equipment and training machines that can benefit athletes and people across the globe who play sports. Believing that machines are subordinate to human beings, a key goal for Sakai is to augment the performance of sports players through the development of tools and machines. Some of the state-of-the-art tools and methodologies he uses in his work are high-resolution sensors, laser-speed sensors, MATLAB and general finite element method analysis software (ANSYS/LS-DYNA). He has developed a shuttlecock launching machine for badminton that can launch at high speed, a high-performance baseball pitching machine that is able to generate an efficient and objective gyro spin and has a high throwing performance and a pitching control method that uses AI.

Abstract The operational drilling history in a particularly challenging shale consistently shows that once the formation's shale reacts, and starts to disperse, in the face of a typical water base mud application, a variety of hole problems are experienced by the operator. These problems include wellbore instability caused by an unstoppable sloughing of the shale; the experiencing of tight hole conditions while performing the wiper trip; caved shale sticking to shakers while drilling; an increased dilution rate due to mud weight; a low LGS % (low gravity solids), and fluid viscosity. To solve this longstanding drilling challenge, a team formed from operator and service provider experts determined via high-level research and testing the need for an innovative new technology of inhibitive fluid chemistry. After extensive testing, the team determined that a particular environmentally friendly Nano Polymer high-performance water-based mud (HPWBM)—one possessing the unique shale inhibition and cutting encapsulation capabilities capable of stabilizing this sticky shale—was the best fit for this application. We will present the investigational learning and effective field trial drilling of high problematic shale that was evaluated during and subsequently the utilization of nanoparticles (NP) to advance water-based mud (WBM) inhibition properties, proven to offer an eco-friendly Nano Polymer HPWBM substitute with the improved thermal and rheological permanency of the overall WBM formulation. Results will display that while providing more effective drilling and wellbore stability, this technology is also a far cleaner industry alternative.

Abstract Myanmar offshore is considered to be a very promising exploration and production (E&P) location for oil and gas but poses significant challenges to drilling and cementing operations. Low temperature at sea bed delays the cement compressive strength development, High pore pressure with steep gradient and low fracture pressure created a very narrow drilling margin, presence of shallow flow in riser-less section further complicated the cementing operation, low density cement with high performance is a must. With the exorbiant cost of Deepwater drilling, much needed fit for purpose cementing technology with efficient logistic support and excellence in execution became crucial. This paper elaborates the cementing challenges at different sections of a recent deep-water well in offshore Mynamar and techniques that were planned and used to address those challenges. This paper will describe in detail the cementing method, how it fit the well situation, how the cement slurry was designed then evaluated and how the logistic support and execution were carried out, resulting in a resounding success.

Background: Bacteria coordinate their behavior as a group via communication with their peers, known as ‘ quorum sensing’. Enterococcus faecalis employs quorum sensing via RNPP-peptides which were not yet reported to be present in mammalian biofluids. Results: Solid phase extraction of murine feces was performed, followed by ultra high performance liquid chromatography (UHPLC–MS/MS) in multiple reaction monitoring (MRM) mode (in total <90 min/sample) for the nine known RNPP peptides. Limits of detection ranged between 0.045 and 52 nM. Adequate identification criteria allowed detection of RNPP quorum sensing peptides in 2/20 wild-type murine feces samples (i.e., cAM373 and cOB1). Conclusion: A fit-for-purpose UHPLC–MS/MS method detected these RNPP peptides in wild-type murine feces samples.

Abstract Background Sorbic acid (E, E-2, 4-hexadienoic acid) is added as a preservative to cheese because of its fungistatic and antimicrobial activity. Objective A facile method for the analysis of sorbic acid that is applicable to sliced processed cheese and grated cheese products. Method A cheese sample and dry-ice mixture was blended and sorbic acid was extracted with methanol and analyzed by HPLC-ultraviolet with external standardization. A large sample size was used to overcome sample inhomogeneity due to imprecise sorbic acid addition techniques during production and sorbic acid migration through the fat over time. Results The method was shown to be accurate for both processed cheese and grated Cheddar cheese, with acceptable spike recovery (93.7, 103.7%, respectively), and no bias (α = 0.05) against an international reference method (p = 0.59, p = 0.13, respectively) was found. Acceptable precision was confirmed for both processed cheese slices and grated Cheddar cheese, with repeatability of 5.3% and 4.3% relative standard deviation, respectively, and intermediate precision Horwitz ratio values of 1.3 and 1.7 for processed cheese slices and grated Cheddar cheese, respectively. Method detection limit and ruggedness experiments further demonstrated the suitability of this method for routine compliance testing. Conclusions A method for high-throughput, routine testing of sorbic acid is described. The method was subjected to single-laboratory validation and was found to be accurate, precise, and fit-for-purpose.
