Halal dating: changing relationship attitudes and experiences among young British Muslims
Young Muslims in the UK are making space to gain greater control over their personal lives through the diction of ‘halal’ and ‘haram’ when reflecting on and negotiating personal relationships. This article explores the significance of ‘halal dating’ within the lived experiences and sexual relationships of young British Muslims. It draws upon 56 in-depth interviews conducted with young (16–30 years) British Muslims of Pakistani heritage. This research shows that, contrary to popular stereotype and widespread expectations, many young British Muslims do date, or have dated. By entertaining the idea that certain forms of dating may be halal, these young Muslims are finding and claiming agency to make relationship choices of their own
Probing microwave fields and enabling in-situ experiments in a transmission electron microscope.
A technique is presented whereby the performance of a microwave device is evaluated by mapping local field distributions using Lorentz transmission electron microscopy (L-TEM). We demonstrate the method by measuring the polarisation state of the electromagnetic fields produced by a microstrip waveguide as a function of its gigahertz operating frequency. The forward and backward propagating electromagnetic fields produced by the waveguide, in a specimen-free experiment, exert Lorentz forces on the propagating electron beam. Importantly, in addition to the mapping of dynamic fields, this novel method allows detection of effects of microwave fields on specimens, such as observing ferromagnetic materials at resonance
Effects of Heparin and Enoxaparin on APP Processing and Aβ Production in Primary Cortical Neurons from Tg2576 Mice
Alzheimer's disease (AD) is caused by accumulation of Aβ, which is produced through sequential cleavage of β-amyloid precursor protein (APP) by the β-site APP cleaving enzyme (BACE1) and γ-secretase. Enoxaparin, a low molecular weight form of the glycosaminoglycan (GAG) heparin, has been reported to lower Aβ plaque deposition and improve cognitive function in AD transgenic mice
After or against secularism: Muslims in Europe
The postsecular has been conceptualized, both in general terms and also in relation to particular countries and religious groups, as a historical shift in which religion is returning from the margins and the shadows to the centre ground of public life (Habermas 2008). From the perspective of religious groups, minorities in particular, narratives of the return of religion are problematic. We develop this argument with reference to British Muslims of Pakistani heritage, and Polish Muslims with mixed heritage
Transmission and Reflection of Millimeter Waves in i-GaAs/n-GaAs Periodic Structures in Voigt Configuration
The paper presents the first experimental results on the in-plane propagation of millimeter waves in GaAs ...n-i-n-i-... type periodic layered structures in the Voigt geometry. The data are found to agree with theoretical calculations based on the effective medium approximation, showing the feasibility of contactless non-destructive probing of periodic layered structures
Interface, Guided and Non-Localized Modes in Superlattices
The numerical dispersion calculations in long-period GaAs/AlAs super-lattice were performed using a local theory with retardation as well as an effective medium approximation. The splitting of the dispersion branches near the transverse optical phonon frequencies and phonon-like to photon-like modes transition were found to depend on the superlattice spatial period. The characteristic frequencies of bulk modes and crossing point of dispersion branches estimated analytically with the use of an effective medium approximation were found to agree with the results of rigorous solution
Optical Properties of Cd 1-x
A simple and convenient model is proposed to elucidate the optical characteristics of CdMnTe crystals using experimental data on light reflection in magnetic field. The model is based on the quasi-oscillator concept accounting both for the exciton and fundamental absorption edge contributions. The energy dependencies of refraction index and absorption coefficient are presented for Mn mole fraction x=20% at the magnetic field values up to 5 T

In-Plane Propagating Coupled Photon-Phonon-Magnetoplasmons, their Field Structure and Dispersion in GaAs/AlAs Superlattices
The dispersion and field structure of in-plane propagating p-polarized waves in n-GaAs/AlAs superlattice is studied in the frequency range below 10 THz in the presence of the steady magnetic field which is perpendicular both to the direction of propagation and periodicity. The existence of non-localized photon-phonon-plasmon modes as well as the magnetic-field-controlled mode localization at selected set of interfaces is predicted
