A Simple Modification of DC Current Septa to Reduce Current Density by Half [PDF]
arXiv, 2023 Circular accelerators typically have one injection and one extraction septum magnet. CEBAF is a recircuating electron linac which has a total of 27 DC current septa and one Lambertson. Current densities range from 28-48 A/mm 2 . Current sheet widths are 5-24 mm, turns count 5-24 and lengths 1000-3000 mm. A design exercise to increase the beam energy to

Laryngoscope Investigative Otolaryngology, 2021 Introduction The nasal mucosal contact points between the two opposing mucosal surfaces leading to the headache had been a point of debate for many years; the intermittent and fixed contact points and their relationship with headache have never been ...

FEM models and Fourier decomposition of three thick septa [PDF]
, 2018 The CEBAF recirculating linear accelerator uses 26 septa: 8 thin, 17 thick and one Lambertson. We report here on detailed FEM models of one thick current-sheet septum, the Lambertson, and a new thick-septum concept which contains features of both. The last has higher-order field components within a factor of two of the current-sheet septum and much ...

Spray characteristics from nasal spray atomization [PDF]
arXiv, 2022 In addition to topical delivery, nasal sprays offer an alternative drug administration route to the systemic circulation, therefore avoiding the need for painful, invasive delivery techniques. Studies on the efficacy of nasal drug delivery to date have been conflicting despite its potential. In particular computational studies, e.g. Computational Fluid

A 77-118 GHz Resonance-free Septum Polarizer [PDF]
Yen-Lin Chen et al. 2014, ApJS, 211, 11, 2014 Measurements of the polarized radiation often reveal specific physical properties of emission sources, such as strengths and orientations of magnetic fields offered by synchrotron radiation and Zeeman line emission, and the electron density distribution by free-free emission.

Nasal septum mucocele in a patient with two other mucoceles of the paranasal sinuses: late complications of maxillofacial trauma [PDF]
Rhinology Online, 2020 Introduction: Mucoceles are pseudocystic lesions that, despite being benign, may cause diverse symptoms related to its expansive nature. Although their most common location in the nose is the frontoethmoidal sinuses, they can occur in other sites.

The nasal septum deviation index (NSDI) based on CBCT data.
Dento maxillo facial radiology, 2016 OBJECTIVE To assess whether three-dimensional morphometric parameters could be useful in nasal septal deviation (NSD) diagnosis and, secondarily, whether CBCT could be considered an adequate imaging technique for the proposed task.

Physical and geometric constraints explain the labyrinth-like shape of the nasal cavity [PDF]
, 2017 The nasal cavity is a vital component of the respiratory system that heats and humidifies inhaled air in all vertebrates. Despite this common function, the shapes of nasal cavities vary widely across animals. To understand this variability, we here connect nasal geometry to its function by theoretically studying the airflow and the associated scalar ...
