The traditional dynamic characteristic analysis of the multi-stage centrifugal pump rotor system is developed assuming the bearing structural parameters with constant values.However, the manufacturing errors will cause the structural parameters to vary around their nominal values and then affect the dynamic characteristics of the bearing-rotor syst
An experimental study is performed to determine the head mechanics of American football helmets equipped with novel fiber energy absorbing material (FEAM).FEAM-based padding materials have substrates of textile fabrics and foam made with nylon fibers using electro-static flocking process.Both linear and angular accelerations of the sport helmets ar
Dyslipidemia, characterized by abnormal lipid levels in the blood, significantly escalates the risk of atherosclerotic cardiovascular disease and requires effective treatment strategies.While existing therapies can be effective, long-term adherence is often challenging.There has been an interest in developing enduring and more efficient solutions.I
A multidisciplinary protocol is proposed to monitor the preservation of fresh pumpkin samples (FP) using three commercial polymeric films: A made of biodegradable cellophane from regenerated cellulose pulp; B from corn starch, cassava and eucalyptus, C made of polylactic acid from corn starch, and a polyethylene film used as reference (REF).Chemica
