The Magnetic Field from Cylindrical Arc Coils and Magnets: A Compendium with New Analytic Solutions for Radial Magnetization and Azimuthal Current

open access: yesAdvanced Physics Research, Volume 3, Issue 7, July 2024.
This study provides analytic solutions for the magnetic field of coils and magnets that have a non‐axisymmetric cylindrical geometry with a rectangular cross‐section. The equations can be readily applied to find the magnetostatic field in linear or non‐linear systems that contain a large set of elements.

The use of high expansion foam for stunning and killing pigs and poultry

open access: yesEFSA Journal, Volume 22, Issue 7, July 2024.
Abstract The EFSA Panel on Animal Health and Welfare (AHAW) was asked to deliver a scientific opinion on the use of high‐expansion foam for stunning and killing pigs and poultry. A dossier was provided by the applicant as the basis for an assessment of the extent to which the method is able to provide a level of animal welfare at least equivalent to ...

The Effect of Sociodemographic Factors on Female Educational Attainment: An Application of the Multipopulation Curie–Weiss Model

open access: yesJournal of Applied Mathematics, Volume 2024, Issue 1, 2024.
In recent times, there have been a lot of advocacies to encourage females of all ages to pursue education to the highest level. The Government of Ghana and its stakeholders have championed this to achieve the Sustainable Development Goal 4 in this regard. However, progress has been on a snail’s pace.

Rigorous treatment of barycentric stellar motion: Perspective and light-time effects in astrometric and radial velocity data

open access: yes, 2014
High-precision astrometric and radial-velocity observations require accurate modelling of stellar motions in order to extrapolate measurements over long time intervals, and to detect deviations from uniform motion caused for example by unseen companions.

Technical Progress and Early Retirement [PDF]

open access: yes
This paper claims that technical progress induces early retirement of older workers. Technical progress erodes technology specific human capital. Since older workers have shorter career horizons, there is less incentive for them or for their employers to

3-dimensional Gravity from the Turaev-Viro Invariant

open access: yes, 1991
We study the $q$-deformed su(2) spin network as a 3-dimensional quantum gravity model. We show that in the semiclassical continuum limit the Turaev-Viro invariant obtained recently defines naturally regularized path-integral $\grave{\rm a}$ la Ponzano ...
