This article describes an inexpensive elastic head support for persons with amyotrophic lateral sclerosis (ALS) and neck muscle weakness and also presents a case series to examine its effectiveness. The device offers support to the head while the user is seated, standing, and walking, providing support for persons in various stages of ALS. The head support system was tested in seven male patien...

Abstract Precision farming (PF) plays a crucial role in the field of agriculture to solve challenges food shortages society. Heterogeneity, multicollinearity, and outliers are problems PF because they can cause bias lead incorrect inferences. However, traditional methods typically assume it be homogenous model, machine learning, data scientists ignore heterogeneity. In this study, aim is identi...

The paper presents an elastic coupling with bolts and intermediary non-metallic elements, which allows for radial axial deviation can absorb shocks torsional vibrations. designed have a particular shape of circular area length equal to the width element, cylindrical larger than diameter groove where elements are mounted, smaller threaded avoid stress concentrators bolt breakage. represents symm...

the micro milling operation is one of the manufacturing processes, which can produce 3d parts in the range of less than a millimetre. miniaturization of components results in increasing the ratio of surface area to volume of components, which in turn increases the role of surface on the component performance. therefore, anticipating the relationship between micro milling parameters and surface ...

Objective: Combined liposuction and abdominoplasty, or lipoabdominoplasty, is particularly helpful in sculpting a more aesthetically pleasing abdominal contour, particularly in the supraumbilical midline groove. This groove, coined the "champagne groove" by one of our patients, is a frequently sought-after attribute by patients. However, liposuction adds time and cost to an already costly abdom...

A multicomponent lattice Boltzmann scheme is used to investigate the surface coating of substrates with two topographical features by a gravity-driven thin liquid film. The considered topographies are U- and V-shaped grooves and mounds. For the case of substrates with two grooves, our results indicate that for each of the grooves there is a critical width such that if the groove width is larger...

This paper presents a hydrodynamic lubrication model to investigate the static and dynamic characteristics of micro-grooved bearings considering journal misalignment. An averaged Reynolds equation with mass conservation is derived numerical procedure solved by finite difference method. The influences eccentricity ratio, misalignment micro-groove parameters on performances aligned/misaligned are...

The synthesis and NMR structural studies are reported for a modular threading tetraintercalator bound to DNA. The tetraintercalator design is based on 1,4,5,8-tetracarboxylic naphthalene diimide units connected through flexible peptide linkers. Aided by an overall C(2) symmetry, NMR analysis verified a threading polyintercalation mode of binding, with linkers alternating in the order minor groo...
