Unknowable bodies, unthinkable sexualities: lesbian and transgender legal invisibility in the Toronto women's bathhouse raid

Although litigation involving sexual orientation and gender identity discrimination claims has generated considerable public attention in recent years, lesbian and transgender bodies and sexualities still remain largely invisible in Anglo-American courts. While such invisibility is generally attributed to social norms that fail to recognize lesbian and transgender experiences, the capacity to 'not see' or 'not know' queer bodies and sexualities also involves wilful acts of ignorance. Drawing from R. v Hornick (2002) a Canadian case involving the police raid of a women's bathhouse, this article explores how lesbian and transgender bodies and sexualities are actively rendered invisible via legal knowledge practices, norms and rationalities. It argues that limited knowledge and limited thinking not only regulate the borders of visibility and belonging, but play an active part in shaping identities, governing conduct and producing subjectivity

Study Of Mass Losses Of Cauliflower At Storage Depending On A Packing Way

Tissues of fresh vegetables are characterized by the high quantity of moisture (80…96 %), active metabolism, low resistance to mechanical lesions, are spoiled fast. Metabolism in cells of tissues, so mass losses, depends on the content of water and dry substances.It is impossible to manage abiotic factors under conditions of open soil. So, there appears a necessity to study the influence of abiotic factors on the process of mass decrease at cauliflower storage that gives a possibility to prognosticate its mass losses and aptitude to storage.The aim of the study was to analyze the influence of weather conditions of the vegetation period of cauliflower, volume, specific mass and porosity of heads and packing methods on the intensity of natural mass losses of cauliflower at storage. The research gives a possibility to decrease natural losses of cauliflower heads and to prolong the storage duration of it. Cauliflower mass losses at the expanse of water evaporation depend on weather conditions of the vegetation period of the plant. It has been established, that there is a middle force reverse connection with the coefficient correlation r=–0,465 between the intensity of water evaporation at cauliflower heads storage and GTC, middle force connection with the coefficient correlation r=0,437 – with the average day temperature, and strong reverse connection r=–0,776 with the relative air humidity. There was elaborated the regression equation that gives an understanding about mass losses of cauliflower heads, packed in PF, at the expanse of water evaporation.The intensity of water evaporation of cauliflower at storage depends on package method. At packing in a stretch-film (SF), the intensity of moisture decrease, % a day, was the least, equal to 0,30–0,31. The ratio between moisture losses to ones of dry substances was 0,45–0,68. At packing in a performed stretch-film (PSF), the intensity of moisture decrease, % a day, was higher a little – 0,37–0,43.The more storage duration of cauliflower of late ripeness was provided by individual packing of heads in a polyethylene stretch-film. This packing type provided less total natural losses of products: in Skywoker F1– 6,0 %, in Kasper F1 and Santamaria F1 – 6,3 %. Natural losses for a day in variants with using a stretch-film were within 0,05–0,06 % depending on hybrid

Chronopotentiometry at platinum electrode in KF-NaF-AlF3-Al2O3 melt

Some features of the mechanism of the anode process on platinum in KF–NaF–AlF3–Al2O3 melt at 750–780 °C depending on the of anodic current density (0.5 mA/cm2 to 2.0 A/cm2) and anodic pulse duration have been studied using chronopotentiometry method. In curves of change in the platinum anode potential a small peak at current densities of 10–30 mA/cm2 and a clear peak at current densities of 0.5–2.0 A/cm2 are recorded when the current is cut on. Analysis of dependencies of the transition time on the current density indicates that the first peak in curve is associated with the formation of an oxide compound on the platinum surface, and the second one is related to hindering the diffusion for delivery of electroactive particles to its surface.The study was supported by the Russian Foundation for Basic Research (grant № 13–03–00829 A)

Twin roll casting and melt conditioned twin-roll casting of magnesium alloys

Recently, BCAST at Brunel University has developed a MCAST (melt conditioning by advanced shear technology) process for conditioning liquid metal at temperature either above or bellow the alloy liquidus using a high shear twin-screw mechanism. The MCAST process has now been combined with the twin roll casting (TRC) process to form an innovative technology, namely, the melt conditioned twin roll casting (MC-TRC) process for casting Al-alloy and Mg-alloy strips. During the MC-TRC process, liquid alloy with a specified temperature is continuously fed into the MCAST machine. By intensive shearing under the high shear rate and high intensity of turbulence, the liquid is transformed into conditioned melt with uniform temperature and composition throughout the whole volume. The conditioned melt is then fed continuously into the twin-roll caster for strip production. The experimental results show that the AZ91D MC-TRC strips with different thicknesses have fine and uniform microstructure. The strip consists of equiaxed grains with a mean size of 60-70μm. The strip displays extremely uniform grain size and composition throughout the whole cross-section. Investigation also shows that both TRC and MC-TRC processes with reduced deformation are effective to reduce the formation of defects, particularly the formation of the central line segregations

Microstructure and creep properties of MRI230D magnesium alloy

The dependency of creep behaviour on the as-cast microstructure of MRI230D Mg alloy produced by ingot casting (permanent mould casting) and high pressure die casting was investigated. A detailed microstructural characterisation and study of creep properties have been accomplished. The alloy in both ingot-casting (IC) and high pressure die-casting (HPDC) conditions consists of á-Mg, C36 ((Mg,Al)2Ca) and Al-Mn rich phases. Microstructural study revealed finer grain size, closely spaced network and increased volume fraction of secondary eutectic phases for HPDC specimen when compared to that of the IC specimen. The grain size variation and denser network of eutectic phases was due to the considerable difference in cooling rate, high degree of undercooling associated with the faster cooling rate following HPDC facilitates the formation of a large number of nuclei in the liquid Mg alloy. The eutectic C36 phases were also observed to be coarser in the case of IC specimen owing to the slower solidification rate. Porosity was discovered significant in the HPDC specimen in comparison to the negligible extent in IC specimen. Following creep tests at 70 MPa stress level and temperature of 175°C and 200°C the HPDC specimens exhibited superior creep resistance as compared to the IC specimens. The significant creep resistance exhibited by the HPDC specimen was primarily due to the dispersion strengthening effect offered by hindering of dislocation movement at the grain boundaries. Stress dependence on the strain rates for the alloys cast by both the technologies were studied and deduced that the dominant creep mechanism was dislocation creep. The same was theortically confirmed from the deformation mechanism map established for Mg alloys. Post creep microstructural studies revealed increased precipitation of C36 phase at the grain boundaries. Larger amount of precipitation was observed in the HPDC specimens due to enhanced pre-existing eutectic phases in the same

Microstructural characterisation and thermal stability of an Mg-Al-Sr alloy prepared by rheo-diecasting

A commercial Mg-6Al-2Sr (AJ62) alloy has been prepared by a semisolid rheo-diecasting (RDC) process. The microstructure of the RDC alloy exhibits typical semisolid solidification features, i.e., 8.4 vol% primary α-Mg globules (23 μm in diameter), formed in the slurry maker at the primary solidification stage, uniformly distributed in the matrix of fine α-Mg grain size (8.2 μm) and intergranular eutectic Al4Sr lamellae, which resulted from secondary solidification inside the die. A ternary Mg-Al-Sr phase was also observed. Heat treatment revealed the extreme thermal stability of the RDC AJ62 alloy. The hardness showed little change up to 12 hours at 450°C, whilst the Al4Sr eutectic lamellae were broken up, spheroidised and coarsened during the annealing. The RDC alloy offers superior mechanical properties, especially ductility, over the same alloy produced by high pressure die-casting

Social Identity Represented in Dai’s Discourse

This research is motivated by the use of language as a marker of da’is (preachers) identity and ideology in the city of Medan represented in their preaching. The outbreak of the spirit of Islam which was marked by the proliferation of Islamic da’wah forums in urban areas, presented a treasure of language problems that could be used as new objects of linguistic analysis. In the discourse of Islamic preaching, language plays an important role that could be used to portray a personal and sociocultural identity of a dai. Even the use of language can also represent the ideology of the dai. The purpose of this study is to find out the linguistic features that shape identity and the ideology represented in the preaching discourse of Dai in the city of Medan. Practically, a phenomenological design was used in this study based on a critical socio-pragmatic approach. The data are in the form of speech collected purposively and analyzed by distributional and contextual method and presented formally and informally.     Keywords: identity, ideology, discourse, urban areas, da’i
