Global warming alters the Arctic on different ecological and social levels, including rising resource availabilities and shifting power relations. In this geographical area, the natural sphere, which is based on the geographical spheres of the earth, and the social sphere are strongly interwoven and therefore sensitive to even small alterations, as a case study of Arctic shipping routes will hi...

introduction: while social media has the potential to be used to make professional and personal connections, it can also be used inappropriately, with detrimental ramifications for the individual in terms of their professional reputation and even hiring decisions. this research explored students’ and faculty members’ perceptions of the acceptability of various social media postings. methods: th...

An envelope echo signal measurement is proposed in this paper using echo signal observation from the 200 kHz echo sounder receiver. The envelope signal without any object is compared with the envelope signal of the sphere. Two diameter size steel ball (3.1 cm & 2.2 cm) and two diameter size air filled stainless steel ball (4.8 cm & 7.4 cm) used in this experiment. The target was positioned abou...

The jamming transition of particles with finite-range interactions is characterized by a variety of critical phenomena, including power-law distributions of marginal contacts. We numerically study a recently proposed simple model of jamming, which is conjectured to lie in the same universality class as the jamming of spheres in all dimensions. We extract numerical estimates of the critical expo...

Light scattering by a small spherical particle, a central topic for electromagnetic scattering theory, is here considered. In this short review, some of the basic features of its resonant scattering behavior are covered. First, a general physical picture is described by a full electrodynamic perspective, the Lorenz–Mie theory. The resonant spectrum of a dielectric sphere reveals the existence o...

Thermo-elastic analysis of a functionally graded hollow sphere is carried out and numerical solutions of displacement, stress and thermal fields are obtained using the Polynomial differential quadrature (PDQ) method. Material properties are assumed to be graded in the radial direction according to a power law function, ho...
