2024年11月25日 · Druschitz and Rambo created molds of metal missile fins, then poured molten metal into the molds to create lightweight replicas for the museum. Rambo used the experience to write and present a paper, a highlight for her resume when she enters the industry’s job market.

The forced mid-expiratory flow (FEF 25-75%) value is a potentially sensitive marker of obstructive peripheral airflow. We aimed to assess whether FEF 25-75% can be an early predictor of chronic obstructive pulmonary disease (COPD). Patients and Methods

Forced expiratory flow at 25–75% of the vital capacity (FEF 25–75%) is a potentially more sensitive parameter for assessing peripheral airway function. This post hoc analysis compared FEF 25–75% with FEV 1 as an endpoint to assess bronchodilator responsiveness in …

The midmaximal forced expiratory flow (FEF 25–75) measures the flow during the middle half of the VC (i.e., from 75% to 25% of VC). The FEV 1 and the FEF 25–75 generally do not depend on respiratory muscle strength. In addition to effort, they depend on the elastic recoil of the lungs and airway resistance and compliance.

2020年11月5日 · FeF 2 nanoparticles embedded with graphitic carbon were successfully synthesized using Fe-MIL-88B. The FeF 2 @GC electrode shows improved discharge capacity, stable retention, and high rate performance in SIBs. The phase transformation of FeF 2 to FeF 3 during cycles is an essential factor for the high electrochemical performance.

FEF 25-75 is the flow rate between 25-75% of the FVC. FEF 25-75 may be more sensitive for obstruction than FEV1/FVC, but less specific. ATS/ERS 2022 guidelines state that FEF 25-75% is highly variable, poorly reproducible, and not specific for small airway disease.

The open-foot pocket design of the Force Fin line gives our divers the ability to endure high work loads and long dive durations without the consequence of leg cramps experienced with other fin designs.
