PCLGold Leads Pipe Stress Evaluation with ASME Code Changes with Shell FEA in Latest Software Release
PCLGold now includes 2024 ASME B31.3 and B31.1 updates, reinforcing code compliance and FEA-based pipe stress analysis with shell models. 'PCLGold automates tee intersection modeling, I-factors, i-factors, and k-factor FEA calcs, plus B31.3 fatigue checks—no manual model rebuilding & it captures worst-case range across all load sets'— Michael Clark, P.E., General Manager of Paulin Research Group HOUSTON, TX, UNITED STATES, June 19, 2025 / / -- Paulin Research Group's 2025.4.0.2787 release incorporates the 2024 ASME B31.1 and B31.3 code updates, augmenting its code coverage for use with its advanced finite element analysis (FEA) capabilities for piping system design and analysis. In PCLGold, these features support continued improvements in localized pipe stress analysis by utilizing shell models in addition to standard beam models where more insight is required. PCLGold integrates directly with existing beam-based piping designs, applying FEA at intersections, nozzles, and other areas of geometric or mechanical complexity. This targeted approach supports more informed decisions during design, analysis, and verification, especially in systems where the typical B31 assumptions may not be valid. The software helps reveal localized stress behavior in scenarios such as: - Friction reversal at supports during thermal expansion and shutdown - Axial and torsional effects on branch connections - Load shifts in overhangs and risers due to condensate or sag - Structural response changes caused by pressure or thermal stiffening The inclusion of 2024 ASME B31.1 and B31.3 updates ensures current code alignment while maintaining PCLGold's broader objective: to improve stress prediction fidelity in critical piping systems. PCLGold's analysis framework is supported by real-world validation, including fatigue, burst, and acoustic testing performed by Paulin Research Group. This foundation helps engineers assess conditions that influence fatigue life, equipment loading, and system reliability. About Paulin Research Group Paulin Research Group (PRG) develops advanced engineering software for the design and analysis of pressure vessels and piping systems, focusing closely on finite element analysis (FEA) and compliance with recognized industry codes.

New study identifies key fixation points for ligament repair
In a groundbreaking development, surgeons have taken a significant leap forward in the field of orthopaedic sports medicine by pinpointing the elusive anatomical sweet spot crucial for treating a common yet debilitating condition: shoulder dislocations, especially those involving trauma to the Inferior Glenohumeral Ligament (IGHL), have long posed a challenge to orthopaedic surgeons. While surgical techniques have evolved, the lack of a clearly defined anatomical insertion point for reconstructing the IGHL has led to inconsistencies in patient outcomes. But that may be about to team led by Dr. Ayyappan V Nair, Senior Consultant Orthopaedic Surgeon at Manipal Hospital Whitefield, Bengaluru, has successfully identified the optimal fixation points for reconstructing the IGHL using the long head of the biceps tendon (LHBT). What's more—they've validated their findings through both cutting-edge computer simulations and arthroscopic cadaveric testing. 'This is the first time anyone has defined and validated what we call the 'isometric point' for IGHL reconstruction,' said Dr. Nair told India Today in an exclusive interview: 'Our goal was to create a biomechanically sound and replicable solution that would bring consistency and reliability to these procedures.'THE SCIENCE BEHIND THE BREAKTHROUGHThe study, published in the Journal of ISAKOS (Vol. 10, Feb 2025), uses Finite Element Analysis (FEA)—a computational method borrowed from mechanical engineering—to model the complex biomechanics of the shoulder joint. The simulations identified two key locations for attaching the LHBT graft: the 3 o'clock position on the glenoid and the 7:30 position on the humerus. These were found to be "isometric" points—areas where the ligament graft maintains a consistent length during shoulder movements, ensuring better function and findings were then validated through arthroscopic cadaveric reconstructions, performed in controlled surgical settings. 'When we executed the reconstruction using the LHBT at these exact positions, we observed near-ideal ligament behaviour throughout the entire range of motion,' said Dr. multidisciplinary research is a joint effort between a clinical orthopaedic team from Manipal Hospitals and a mechanical engineering research group, supported by a substantial grant from the Karnataka Technical Council. 'It's a true blend of medical innovation and engineering precision,' added Dr. THIS MATTERSCurrent techniques for IGHL reconstruction are based largely on a surgeon's experience and empirical judgement. The absence of an anatomically validated isometric point often results in variable results and, in many cases, recurrence of instability.'By identifying and validating these isometric points, we're laying the foundation for robot-assisted and navigation-guided shoulder surgeries,' Dr. Nair explained: 'Our approach not only optimises joint biomechanics but also reduces stress on the reconstructed ligament—ultimately improving patient outcomes.'WHAT'S NEXT?While the innovation has been successfully demonstrated in cadaveric models, the next step is to begin clinical trials on live patients. If successful, this new technique could soon become a global standard in managing complex shoulder study also opens doors for Computer-Assisted Orthopaedic Surgery (CAOS) and precision-driven procedures using AI and robotics—futuristic tools that can deliver highly reproducible surgical is not just a step forward for shoulder surgery,' said Dr. Nair. 'It's a leap toward the future of precision orthopaedics. And we're proud that this pioneering work has been done right here in India.'This landmark study represents a significant advance in the pursuit of precision and consistency in orthopaedic surgery. By identifying and validating the isometric points for IGHL reconstruction, Dr. Ayyappan V Nair and his multidisciplinary team have not only addressed a critical gap in shoulder instability treatment but also paved the way for future innovations like robot-assisted and AI-driven surgical the medical community awaits the results of upcoming clinical trials, this research stands as a powerful example of how engineering, technology, and surgical expertise can come together to redefine standards of care—offering new hope to patients around the world suffering from chronic shoulder by: Dr. Ayyappan V Nair, Consultant – Shoulder surgery, sports medicine and Aathroscopy, Manipal Hospital Whitefield, Sarjapur, Jayanagar

‘Extinct' marsupial might be alive and ‘evading detection' in Australia, study says
A tiny marsupial species declared extinct decades ago may still be hopping around in the deserts of Australia — and a new study offers a potential roadmap for its rediscovery. The desert rat-kangaroo, or Caloprymnus campestris — a rodent-like creature with large hind legs — is steeped in mystery. It was last seen nearly a century ago, in 1930. And it was officially designated extinct in 1994, likely due, in part, to predation from foxes and cats. Now, all that scientists have to show for the species is a handful of skeletons kept in museums. But, in recent years there have been numerous unconfirmed sightings of the species, indicating it could be extant. With these sightings in mind, scientists have conducted research — using museum skeletons — that could help rediscover the species, according to a study published on Feb. 25 in the Journal of Experimental Biology. Pinpointing its habitat It turns out, the key to locating the desert rat-kangaroo could lie in its skull. Using computer models of museum specimen skulls, the research team — led by Rex Mitchell from Flinders University — implemented a technique known as Finite Element Analysis (FEA). This allowed them to test the skulls' potential to handle forces that occur during biting. By comparing the results to those from related species, such as bettongs and potoroos, they shed light on the desert rat-kangaroo's diet. 'We were surprised to find the heftier skull of the desert rat-kangaroo isn't necessarily adapted for biting into harder foods,' Mitchell said in a university news release. 'When we included the animal's smaller size into the analysis, the robust features of the desert rat-kangaroo's skull were only found to be effective enough to handle eating a softer range of foods.' This discovery could prove pivotal in narrowing search efforts to specific regions in Australia where softer foods — such as leafy plants — still grow, potentially increasing the likelihood of finding the rare creature. 'Finetuning the search through understanding the animals' diet better might just resurrect the little desert survivor…' Mitchell said. Specifically, scientists mentioned the Sturt Stony Desert, an outback desert in South Australia, as a potential place to look. 'It is plausible that a small, nocturnal species could be evading detection in the vast inland desert,' Vera Weisbecker, one of the study authors, said in the release. The findings serve 'as an ongoing reminder that extinction declarations might not always be the end of the story,' Weisbecker added. The other study authors were Meg Martin and Stephen Wroe.

Teachers' union urges Florida lawmakers to reject governor's 'inadequate' education budget
The Brief The Florida Education Association says the governor's proposed budget doesn't meet the needs of public schools and students. Gov. Ron DeSantis announced his budget proposals at a news conference on Monday. The statewide teachers' union is asking the Florida Legislature to increase funding. TALLAHASSEE, Fla. - Florida's statewide teachers' union is strongly criticizing Governor Ron DeSantis' proposed budget, arguing that it falls short of meeting the needs of public schools and students. The union is urging the state Legislature to "fully commit" to public education by increasing funding. What they're saying The Florida Education Association says the budget fails to address critical issues like low teacher pay, staff shortages and declining student performance. While the proposal does include small pay increases for educators, the union argues that the raises do not keep pace with inflation and will not significantly improve per-student funding. PREVIOUS: Governor DeSantis unveils $115.6B proposed budget for 2025-26 fiscal year "The state of Florida, we don't set teacher salaries," Gov. DeSantis said in Tallahassee on Monday when announcing the proposed budget. "That's done on a district-by-district basis. Sometimes those are negotiations between districts and the school unions. And the school unions, quite frankly, have all have other interests are not necessarily just looking to help teachers." By the numbers Florida already ranks near the bottom in average teacher salaries, and the FEA says this budget does little to change this. Another major concern is over the governor's push for school vouchers. The budget allocates $3.3 billion to the program, which allows students to use taxpayer-funded vouchers for private school tuition. That's double the amount set aside for teacher salaries. Then there's the 13% cut in funding for Exceptional Student Education (ESE). "Look, students with special needs in the state of Florida have long been shortchanged," FEA president Andrew Spar told FOX 13 News, "instead of really investing in what students with special needs require, such as having teacher assistance with them in the classroom, making sure that they're in smaller classes, that they have additional curriculum support." The union wants lawmakers to invest an additional $1,000 per student, fund repairs to aging school buildings, and shift away from standardized testing. They're also pushing for more oversight of private and charter schools that receive public funding. "I think the biggest headline is, once again, Florida continues to underfund its public schools," Spar said. "We are among the worst in the nation in supporting our public schools. Teachers in the state of Florida, the average teacher pay ranks 50th in the nation. And what this budget that the governor has proposed does is to ensure that we remain 50th in the nation and average teacher pay near the bottom in the nation in funding for our schools. And that's just not acceptable at a critical moment in our country's history."
