Esta pesquisa, por meio da abordagem de investigação estudo caso, tem como objeto a calça jeans. Seu objetivo principal é comparar dois processos lavanderia em jeans aplicados este mesmo produto, estimando os custos e recursos utilizados cada método, que foram nomeados tradicional eco. Para tanto, abordamos brevemente história do jeans, o ciclo vida dos produtos sustentabilidade na moda, aprese...

We use numerical simulations of the fragmentation of a 1000 M⊙ molecular cloud and the formation of a stellar cluster to study how the initial conditions for star formation affect the resulting initial mass function (IMF). In particular, we are interested in the relation between the thermal Jeans mass in a cloud and the knee of the initial mass function, i.e. the mass separating the region with...

Criterion of the Jeans instability of interstellar gas clouds which are gravitationally coupled with weakly interacting massive particles is revisited. It is established that presence of the dark matter always reduces the Jeans length, and in turn, Jeans mass of the interstellar gas clouds. Astrophysical implications of this effect are discussed. Subject headings: dark matter — gravitation — in...

Abstract Typical observers in the universe do not follow smooth Hubble expansion, but move relative to it. Such bulk peculiar motions introduce a characteristic scale that is closely analogous familiar Jeans length. This “peculiar length” marks threshold below which relative-motion effects dominate linear kinematics. There, cosmological measurements can vary considerably between bulk-flow frame...

denim is a casual garment normally used by young people and extremely influential in shaping the fashion industry. among various garments, these garments are subjected to innovations. this work is an attempt to compare the different methods of stone washing using pumice stones, acid cellulases and neutral cellulases or in combination of these methods. the effects of different processing conditi...

In this paper we study the gravitational instability in presence of viscosity. In particular, the standard Jeans Mechanism is analyzed taking into account bulk-viscosity effects in the first-order Newtonian dynamics. We show how the perturbation evolution is damped by dissipative processes and the top-down fragmentation mechanism is suppressed for strong viscous effects. The critical value of t...

BACKGROUND Sandblasting of jeans in small Turkish workshops has recently been recognized as a cause of silicosis. CASE SERIES Between August 2004 and March 2006, we admitted 16 young men with a history of working in small workplaces producing sandblasted jeans. Of these, 14 presented with respiratory symptoms and the remaining two through awareness of their work colleagues. In the first two c...
