2Speed and surface steepness affect internal tibial loading during running显示文摘Background:Internal tibial loading is influenced by modifiable factors with implications for the risk of stress injury.Runners encounter varied surface steepness(gradients)when running outdoors and may adapt their speed according to the gradient.This study aimed to quantify tibial bending moments and stress at the anterior and posterior peripheries when running at different speeds on surfaces of different gradients.Methods:Twenty recreational runners ran on a treadmill at 3 different speeds(2.5 m/s,3.0 m/s,and 3.5 m/s)and gradients(level:0%;uphill:+5%,+10%,and+15%;downhill:-5%,-10%,and-15%).Force and marker data were collected synchronously throughout.Bending moments were estimated at the distal third centroid of the tibia about the medial-lateral axis by ensuring static equilibrium at each 1%of stance.Stress was derived from bending moments at the anterior and posterior peripheries by modeling the tibia as a hollow ellipse.Two-way repeated-measures analysis of variance were conducted using both functional and discrete statistical analyses.Results:There were significant main effects for running speed and gradient on peak bending moments and peak anterior and posterior stress.Higher running speeds resulted in greater tibial loading.Running uphill at+10%and+15%resulted in greater tibial loading than level running.Running downhill at-10%and-15%resulted in reduced tibial loading compared to level running.There was no difference between+5%or-5%and level running.Conclusion:Running at faster speeds and uphill on gradients≥+10%increased internal tibial loading,whereas slower running and downhill running on gradients≥-10%reduced internal loading.Adapting running speed according to the gradient could be a protective mechanism,providing runners with a strategy to minimize the risk of tibial stress injuries.Hannah Rice Markus Kurz Patrick Mai Leon Robertz Kevin Bill Timothy R.Derrick Steffen Willwacher 2024Journal of Sport and Health Science2024,13,1:1

6Integrating the ISO 14034 standard as a platform for carbon capture and utilization technology performance evaluation显示文摘Independent testing and verification of emerging technologies are vital parts of the technology-commercialization process.With the rapid development of carbon capture and utilization(CCU)technologies,where existing standards and certifications do not exist,independent verification approaches and guidelines can provide a means to obtain credible information for an emerging market.The ISO 14034:2016-Environmental Management:Environmental Technology Verification(ETV)standard can serve as a foundational platform to ensure the consistency,quality and credibility of data on CCU technology performance,enabling direct comparisons between technologies and reducing risk to decision-makers regarding potential investment,future deployment and ultimate impacts of CCU innovations.Applying the fundamental principles of ISO 14034 to the evaluation of nine finalist CCU technologies competing in the NRG COSIA Carbon XPRIZE ensured that data used to evaluate competitors was of high quality,consistent across technologies and met the information needs of the XPRIZE and competition judges responsible for selecting winners.The approaches outlined here,including verification parameters and verification tasks for both XPRIZE-specific technology evaluations and full CCU technology evaluation by an accredited entity in conformance with the ISO 14034 standard,provide insight into the potential benefits-methodological consistency,high-quality data,independent oversight,methodological flexibility and broad applicability-and limitations-technology readiness and applicability,verification and instrumentation costs and lack of specificity-of the approach in an application for the evaluation of emerging technologies.Further application of the ISO 14034 standard and principles,developed through a consensus approach that incorporates other developing guidelines,can drive consistency and credibility for technology-performance evaluations across the CCU sector,ultimately leading to reduced risk and improved market access for new innovations.Tim Hansen Kevin McCabe Bill Chatterton Michael Leitch 2021Clean Energy2021,5,4:0
7Best practices for measurement and impact on performance evaluation for novel carbon-utilization process technologies显示文摘The NRG COSIA Carbon XPRIZE-a$20 million prize competition focused on the development and scaling of innovative carbon-capture and-utilization technologies-placed credible data at the forefront of its scoring and ranking approach for the selection of prize-winners.To guarantee the quality of the submitted data,independent third-party verifiers reviewed each candidate technology and data set.While the Carbon XPRIZE contenders demonstrated a variety of CO_(2)-utilization technologies at various levels of technical maturity and scale,it was found that early evaluation of the impact of measurements on process performance parameters via sensitivity analysis should influence the selection of instruments that have appropriate accuracy.In addition to appropriate accuracy,this assessment can lead to reduced costs associated with instrumentation rather than simply buying the‘best’instrument while simultaneously ensuring that uncertainties are kept as low as possible.With proper pre-planning,good engineering practice and good measurement practice,it is possible to optimize uncertainty against the costs and usability of instrumentation and data systems.Tim Hansen Kevin McCabe Bill Chatterton Michael Leitch Patrick Woolcock 2021Clean Energy2021,5,4:0
8补给触发显示文摘在临床药物开发阶段,首先生产出主要有效成分,然后在临床试验的同时确定配方。更快地推动新药物销售的需要正给临床试验带来更大的压力。因此必须做好详尽的计莉预测供应链的需求,同时确保有足够的药物可用于满足正在进行的和未来的研究需要。加速临床研究经常意昧着必须在更短的交货期限内,以较少原材料开始研究,因此可利用的供给更少。对赞助临床试验的制药公司的供应商来说,这意昧着一个重大挑战。Kevin Wightman Bill Byrom 2006经济导报(医药技术)2006,,3:0
