Negotiating queer and religious identities in higher education: queering ‘progression’ in the ‘university experience’
This article addresses the negotiation of ‘queer religious’ student identities in UK higher education. The ‘university experience’ has generally been characterised as a period of intense transformation and self-exploration, with complex and overlapping personal and social influences significantly shaping educational spaces, subjects and subjectivities. Engaging with ideas about progressive tolerance and becoming, often contrasted against ‘backwards’ religious homophobia as a sentiment/space/subject ‘outside’ education, this article follows the experiences and expectations of queer Christian students. In asking whether notions of ‘queering higher education’ (Rumens 2014 Rumens, N. 2014. “Queer Business: Towards Queering the Purpose of the Business School.” In The Entrepreneurial University: Public Engagements, Intersecting Impacts, edited by Y. Taylor, 82–104. Basingstoke: Palgrave Macmillan.) ‘fit’ with queer-identifying religious youth, the article explores how educational experiences are narrated and made sense of as ‘progressive’. Educational transitions allow (some) sexual-religious subjects to negotiate identities more freely, albeit with ongoing constraints. Yet perceptions of what, where and who is deemed ‘progressive’ and ‘backwards’ with regard to sexuality and religion need to be met with caution, where the ‘university experience’ can shape and shake sexual-religious identity
Angle-resolved optically detected magnetic resonance as a tool for strain determination in nanostructures
In this paper, we apply the angle-resolved Optically Detected Magnetic
Resonance (ODMR) technique to study series of strained (Cd, Mn)Te/(Cd, Mg)Te
quantum wells (QWs) produced by molecular beam epitaxy. By analyzing
characteristic features of ODMR angular scans, we determine strain-induced
axial-symmetry spin Hamiltonian parameter D with neV precision. Furthermore, we
use low-temperature optical reflectivity measurements and X-ray diffraction
scans to evaluate the local strain present in QW material. In our analysis, we
take into account different thermal expansion coefficients of GaAs substrate
and CdTe buffer. The additional deformation due to the thermal expansion
effects has the same magnitude as deformation origination from the different
compositions of the samples. Based on the evaluated deformations and values of
strain-induced axial-symmetry spin Hamiltonian parameter D, we find strain
spin-lattice coefficient G11 = (72.2 +- 1.9) neV for Mn2+ in CdTe and shear
deformation potential b = (-0.94 +- 0.11) eV for CdTe
Short-Lived Trace Gases in the Surface Ocean and the Atmosphere
The two-way exchange of trace gases between the ocean and the atmosphere is important for both the chemistry and physics of the atmosphere and the biogeochemistry of the oceans, including the global cycling of elements. Here we review these exchanges and their importance for a range of gases whose lifetimes are generally short compared to the main greenhouse gases and which are, in most cases, more reactive than them. Gases considered include sulphur and related compounds, organohalogens, non-methane hydrocarbons, ozone, ammonia and related compounds, hydrogen and carbon monoxide. Finally, we stress the interactivity of the system, the importance of process understanding for modeling, the need for more extensive field measurements and their better seasonal coverage, the importance of inter-calibration exercises and finally the need to show the importance of air-sea exchanges for global cycling and how the field fits into the broader context of Earth System Science
Surface-enhanced Raman scattering in graphene deposited on AlGaN/GaN axial heterostructure nanowires
The surface-enhanced Raman scattering in graphene deposited on AlxGa1-xN/GaN
axial heterostructure nanowires was investigated. The intensity of graphene
Raman spectra was found not to be correlated with aluminium content. Analysis
of graphene Raman bands parameters, KPFM and electroreflectance showed a
screening of polarization charges. Theoretical calculations showed that plasmon
resonance in graphene is far beyond the Raman spectral range. This excludes the
presence of an electromagnetic mechanism of SERS and therefore suggests the
chemical mechanism of enhancement
Pharmacokinetic and behavioral characterization of a longterm antipsychotic delivery system in rodents and rabbits
Rationale: Non-adherence with medication remains the major correctable cause of poor outcome in schizophrenia. However, few treatments have addressed this major determinant of outcome with novel long-term delivery systems.
Objectives: The aim of this study was to provide biological proof of concept for a long-term implantable antipsychotic delivery system in rodents and rabbits.
Materials and methods: Implantable formulations of haloperidol were created using biodegradable polymers. Implants were characterized for in vitro release and in vivo behavior using prepulse inhibition of startle in rats and mice, as well as pharmacokinetics in rabbits.
Results: Behavioral measures demonstrate the effectiveness of haloperidol implants delivering 1 mg/kg in mice and 0.6 mg/kg in rats to block amphetamine (10 mg/kg) in mice or apomorphine (0.5 mg/kg) in rats. Additionally, we demonstrate the pattern of release from single polymer implants for 1 year in rabbits.
Conclusions: The current study suggests that implantable formulations are a viable approach to providing long-term delivery of antipsychotic medications in vivo using animal models of behavior and pharmacokinetics. In contrast to depot formulations, implantable formulations could last 6 months or longer. Additionally, implants can be removed throughout the delivery interval, offering a degree of reversibility not available with depot formulations

Application of new methods of environment analysis and assessment in landscape audits : case studies of urban areas like Czestochowa, Poland
Following the 2000 European Landscape Convention, a new act strengthening landscape protection
instruments has been in force since 2015. It sets forth legal aspects of landscape shaping (Dziennik Ustaw 2015, poz.
774) and introduces landscape audits at the province level. A landscape audit consists in identification and
characterization of selected landscapes, assessment of their value, selection of so-called priority landscapes and
identification of threats for preservation of their value. An audit complies with GIS standards. Analyses use source
materials, i.e. digital maps of physical-geographical mesoregions, current topographic maps of digital resources of
cartographic databases, latest orthophotomaps and DTMs, maps of potential vegetation, geobotanic regionalization,
historic-cultural regionalization and natural landscape types, documentation of historical and cultural values and
related complementary resources. A special new methodology (Solon et al. 2014), developed for auditing, was tested
in 2015 in an urban area (Myga-Piatek et al. 2015). Landscapes are characterized by determining their analytic
(natural and cultural) and synthetic features, with particular focus on the stage of delimitation and identification of
landscape units in urban areas. Czestochowa was selected as a case study due to its large natural (karst landscapes of
the Czestochowa Upland, numerous forests, nature reserves) and cultural (Saint Mary’s Sanctuary, unique urban
architecture) potential. Czestochowa is also a city of former iron ore and mineral resources exploitation, still active
industry, dynamic urban sprawl within former farming areas, and dynamically growing tourism. Landscape
delimitation and identification distinguished 75 landscape units basing on uniform landscape background (uniform
cover and use of the land). Landscape assessment used a new assessment method for anthropogenic transformation of
landscape – the indicator describing the correlation between the mean shape index (MSI) and the Shannon diversity
index (SHDI) (Pukowiec-Kurda, Sobala 2016). Particular threats and planning suggestions, useful in development of
urban areas, were presented for selected priority landscapes
