The effect of material type, yarn count , and treatment with water-repellent materials on some of the natural and mechanical properties of car cover fabrics

open access: yesJournal of Architecture, Art & Humanistic Science, 2022
Car covers are considered basic for the preservation of cars of various weather factors such as rain, dust, sun and others. So, we use the next row materials for warp ( cotton 100% ) and yarn count 16/1 and different types of weft materials ( cotton 100%

The Cosmological Bootstrap: Spinning correlators from symmetries and factorization [PDF]

open access: yesSciPost Physics, 2020
We extend the cosmological bootstrap to correlators involving massless spinning particles, focusing on spin-1 and spin-2. In de Sitter space, these correlators are constrained both by symmetries and by locality.

Objective Evaluation of Total Hand Value for Bedsheet

open access: yesJournal of Natural Fibers, 2023
The aim of this paper is to develop an objective set of hand equations for bedsheet fabrics that are produced from conventional or non-conventional fibers such as cotton, polyester, modal, viscose, Excel, and their blends. In order to evaluate the fabric

Shadow of a spinning black hole in an expanding universe [PDF]

open access: yesPhysical Review D, 2020
We study the influence of the cosmic expansion on the size of the shadow of a spinning black hole observed by a comoving observer. We first consider that the expansion is driven by a cosmological constant only and build the connection between the Kerr-de
