Unregulated Desires: Anomie, the “Rainbow Underclass” and Second-generation Alevi Kurdish Gangs in London [PDF]

open access: yes, 2020
This article offers a case study of the adaptation strategies of a section of second-generation young male Alevi Kurds in London and the social conditions which make some of them more prone to join gangs and to reject mainstream institutions in their ...

Governing equations of tissue modelling and remodelling: A unified generalised description of surface and bulk balance [PDF]

open access: yes, 2016
Several biological tissues undergo changes in their geometry and in their bulk material properties by modelling and remodelling processes. Modelling synthesises tissue in some regions and removes tissue in others.

The Effect of the Kraft Pulping Process, Wood Species, and pH on Lignin Recovery from Black Liquor

open access: yesFibers, 2022
Lignin has shown a great potential to produce fuels, value-added chemicals, and functional materials due to its high-energy density and intrinsic aromatic-based structure.

Noise-induced flow in quasigeostrophic turbulence with bottom friction [PDF]

open access: yes, 1999
Randomly-forced fluid flow in the presence of scale-unselective dissipation develops mean currents following topographic contours. Known mechanisms based on the scale-selective action of damping processes are not at work in this situation.

Estimating Terminal Velocity of Rough Cracks in the Framework of Discrete Fractal Fracture Mechanics [PDF]

open access: yes, 2010
In this paper we first obtain the order of stress singularity for a dynamically propagating self-affine fractal crack. We then show that there is always an upper bound to roughness, i.e. a propagating fractal crack reaches a terminal roughness.

Calculation of Coalbed Methane Resources in Mining Stability Zone Based on Gas Emission

open access: yesMeikuang Anquan, 2020
To calculate the coalbed methane resources in the stable area affected by coal mining, firstly, based on the height of roof caving zone and the water conducting fracture zone, the depth of floor failure zone, and the limit gas emission width of coal ...

Balance assessment of material and energy biosphere flows and the energy industry in an industrial region [PDF]

open access: yesE3S Web of Conferences, 2021
The balance assessment of biosphere material and energy flows and those resulting from economic activity in the industrial region is carried out. The analysis is based on the use of stability indicators of the region's socio-ecological and economic ...

Temperature scaling in a dense vibro-fluidised granular material [PDF]

open access: yes, 1999
The leading order "temperature" of a dense two dimensional granular material fluidised by external vibrations is determined. An asymptotic solution is obtained where the particles are considered to be elastic in the leading approximation.

Dislocation theory as a 3-dimensional translation gauge theory [PDF]

open access: yes, 1999
We consider the static elastoplastic theory of dislocations in an elastoplastic material. We use a Yang-Mills type Lagrangian (the teleparallel equivalent of Hilbert-Einstein Lagrangian) and some Lagrangians with anisotropic constitutive laws.
