Methodology for Evaluating the Cutting Force of Planar Technical Blades Used in Flatfish Processing

Micromachines, 2021
In the food industry, there are many varieties of technical blades with different contours as well as different cutting edge geometries. The evaluation of the ability of technical blades to separate (cut) animal tissues is not a simple task and is ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

PENENTUAN PENUMPULAN PISAU PADA PERMUKAAN KAYU

Jurnal Penelitian Hasil Hutan (Journal of Forest Products Research), 2017
The wear of wood cutting tools is, generally, the process which makes a usable tool unfit for continued use. The replacement of the worn cutter either by reconditioning or substitution of a new one represents a necessary cost which can be minimized by ...

An Innovative Experimental Study of Corner Radius Effect on Cutting Forces [PDF]

, 2014
The cutting forces are often modelled using edge discretisation methodology. In finish turning, due to the smaller corner radii, the use of a local cutting force model identified from orthogonal cutting tests poses a significant challenge. In this paper,

Feasibility and Tolerability of Performing Portable MRI for Neurological Disorders in an Outpatient Neurology Clinic: A Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Accessing brain magnetic resonance imaging (MRI) can be challenging, especially for underserved patients, which may lead to disparities in neurological diagnosis. Method This mixed‐methods study enrolled adults with one of four neurological disorders: mild cognitive impairment or dementia of the Alzheimer type, multiple sclerosis ...

Hip Morphology–Based Osteoarthritis Risk Prediction Models: Development and External Validation Using Individual Participant Data From the World COACH Consortium

Arthritis Care &Research, EarlyView.
Objective This study aims to develop hip morphology‐based radiographic hip osteoarthritis (RHOA) risk prediction models and investigates the added predictive value of hip morphology measurements and the generalizability to different populations. Methods We combined data from nine prospective cohort studies participating in the Worldwide Collaboration ...

Modelling of cutting force in hard whirling of ball screws based on uncut chip geometry

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2023
Hard whirling is a highly efficient and green process for precision ball screw machining. Due to the intermittent cutting characteristics and the helical motion of the tool, the cutting forces are periodic and time-varying, making it extremely ...
