Handheld-Impedance-Measurement System with seven-decade capability and potentiostatic function
No full textThis paper describes design and test of a new impedance-measurement system for nonlinear devices that exhibits a seven-decade range and works down to a frequency of 0.01 Hz. The system is specifically designed for electrochemical measurements, but the proposed architecture can be employed in many other fields where flexible signal generation and analysis are required. The system employs an unconventional signal generator based on two pulsewidth modulation (PWM) oscillators and an autocalibration system that allows uncertainties of less than 3% to be obtained over a range of 1 kΩ to 100 GΩ. A synchronous demodulation processing allows the noise superimposed to the low-amplitude input signals to be made negligibl

Exposure-Tolerant Imaging Solution forCultural Heritage Monitoring
No full textThis paper describes a simple and cheap solution specifically designed for monitoring the degradation of thin coatings employed for metal protection. The proposed solution employs a commercial photocamera and a frequency-domain-based approach that is capable of highlighting the surface uniformity changes due to initial corrosion. Even though the proposed solution is specifically designed to monitor the long-time performance of protective coatings employed for the restoration of silver artifacts, it can be successfully used also for assessing the conservation state of other ancient metallic works of art. The proposed solution is made tolerant to exposure changes by using a procedure for sensor nonlinearity identification and correction, does not require a precise lighting control, and employs only free open-source software, so that its overall cost is very low and can be used also by not specifically trained operator
Young people's housing transitions in context
No full textThe transition to adulthood is frequently characterised as delayed or extended in the contemporary period, in the UK as elsewhere. Studies have addressed changing school-to-work transitions, for example, the extension of full-time education and expansion of higher education, as well as changing patterns in family formation and partnership, including the postponement of marriage and childbearing. Some of these changes have been associated with increasing rates of living alone or ‘solo- living’ and living in shared housing. However, the nature of young people’s housing transitions has received less attention and this paper provides a background to a study which specifically addresses the housing transitions of young people aged between 25 and 34 years old living in ‘non-family’ households, that is, living alone or sharing with others. The paper concludes with a short overview of the project and its main research focu
Jews and gender in British literature 1815-1865.
No full textPhDThis thesis examines the variety of relationships between Jews and gender in early
to mid-nineteenth century British literature, focussing particularly on representations
of and by Jewish women. It reconstructs the social, political and literary context in
which writers produced images and narratives about Jews, and considers to what
extent stereotypes were reproduced, appropriated, or challenged. In particular it
examines the ways in which questions of gender were linked to ideas about religious
or racial difference in the Victorian period.
The study situates literary representations of Jews within the context of
contemporary debates about the participation of the Jews in the life of the modern
state. It also investigates the ways in which these political debates were gendered,
looking in particular at the relationship between the cultural construction of
femininity and English national identity.
It first considers Victorian culture's obsession with Rebecca, the Jewess created in
Walter Scott's influential novel Ivanhoe (1819). It examines Rebecca's refusal to
convert to Christianity in the context of Scott's discussion of racial separatism and
modern national unity.
Evangelical writers like Annie Webb, Amelia Bristow and Mrs Brendlah were
prolific literary producers, and preoccupied with converting Jewish women.
Particularly during the 18'40s and 1850s, evangelical writing provided an important
forum for the construction and consolidation of women's national identity.
Grace Aguilar's writing was an attempt to understand Jewish identity within the
terms of Victorian domestic ideology. In contrast, Celia and Marion Moss, in their
historical romances, offered narratives of female heroism and national liberation,
drawing on the contemporary debate about slavery.
Benjamin Disraeli's construction of a "tough version of Jewish identity was a
response both to the contemporary stereotype of the feminised Jew and to the debate
about Jewish emancipation. It also drew on the virile ideology of the Young England
movement of the 1840s
The influence of herring (Clupea harengus) biomass and distribution on killer whale (Orcinus orca) movements on the Norwegian shelf
No full textKiller whales (Orcinus orca) have a cosmopolitan distribution with a broad diet ranging from fish to marine mammals. Regional populations show local prey specialization and their movements are tightly linked to those of their prey. Norwegian killer whales are known to feed extensively on Norwegian spring spawning (NSS) herring (Clupea harengus). Over the last decade, killer whales have begun to readily been observed feeding on high concentrations of overwintering herring in some fjords of northern Norway. Killer whale offshore behavior is less well understood, specifically their reliance on herring as a prey resource outside of the fjord systems. We used movement parameters extracted from 29 killer whale satellite tracks on the Norwegian shelf and related their movements to herring biomass and distribution. Two techniques were used to estimate herring biomass, one based on survey data, and the other based on a simulated ecosystem model. Mixed effects modeling was then used to estimate the effect of herring biomass and diel variations in light levels, on the whales’ movement parameters. We found that killer whales tend to follow the herring when they leave their coastal overwintering areas for their spawning grounds. Individual whale movement characteristics changed from fast directed travel in areas of low herring biomass towards slower non-directed travel when relative herring biomass increased. This suggests that whales feed on herring when they encounter dense concentrations on the Norwegian shelf. Relationships between killer whale movement patterns and herring biomass were consistent for both survey- and simulation-based herring fields. This highlights the potential for using model-based estimates of prey distribution when interpreting predator behavior. We conclude that NSS herring constitutes an important prey resource for killer whales, both during the overwintering and subsequently until the end of the spawning events. Killer whale movements can potentially assist in identifying previously unknown NSS herring aggregations
