A jyotirliṅga (“liṅga of light”) is one of the foremost ways that the deity Śiva has been represented in mythology and art. It is an important sub-type of the deity’s liṅga (mark, sign, phallus). A well-known example is the network of twelve pilgrimage sites spread across the Indian subcontinent. In their related mythology each site accounts for a theophany of Śiva in light form, descending from heaven and remaining at the pilgrimage center in the form of a liṅga. The development and growth of this pilgrimage network within the sacred topographies of Śiva is relatively understudied, but new scholarship in the Purāṇas and Śaivadharma traditions as well as the archaeology of individual sites connected to these texts are helping to alleviate this paucity. Beginning in roughly the 10th century, fire and light imagery is integrated into different forms of Śaiva ritual, myth, and art as part of a strategy to popularize Śaivism. While the theme ‘God is light’ (numen lumen) is ubiquitous across religious traditions, its integration within Śaivism occurred for particular historical, theological, and sectarian reasons. One is the development of mythic themes related to light and fire as seen through the liṅgodbhavamūrti (form arising from the liṅga) and Devadāruvana (Pine Forest) mythemes. The earliest example of the liṅgodbhavamūrti likely dates to the 7th century, while the Devadāruvana can be traced to the Mahābhārata (Book 10.17). A second reason for the development of fire and light imagery is seen through the Śaiva encounter with Gupta period images of the Buddha’s fiery form and Buddhist commentarial literature. In addition, Śaiva encounters with universalizing tendencies within Islam, especially seen through the rise of Viśveśvara (Lord of the Universe) in Vārāṇasī, informed this developing tradition. Scholarship and sources about jyotirliṅgas can be structured around three major categories: the network of twelve jyotirliṅgas, the liṅgodbhavamūrti, and the Devadāruvana. Each of these categories has a diverse body of textual, inscriptional, art historical, and archaeological sources.

Abstract We studied the association between gamma-glutamyltransferase (GGT) and apolipoproteins A or B in serum of 42 patients with various hepatobiliary diseases. Binding of the enzyme to apolipoprotein A is not related to a clearly defined disease, but appears to be mainly influenced by the ratio of total cholesterol to GGT activity. An important fraction of GGT activity is associated with apolipoprotein B in patients with icteric or anicteric cholestasis. Conversely, in noncholestatic patients, the percentage of apolipoprotein B-bound GGT activity is low. Addition of the "heavy" form of GGT, obtained by solubilizing the membrane-bound enzyme with detergents, to a serum with low GGT activity led to the binding of the enzyme only to apolipoprotein A. The "light" form of GGT, obtained by limited proteolysis of the "heavy" form and added to the same serum, did not bind to either apolipoprotein A or apolipoprotein B. Thus, the association between the serum enzyme and apolipoprotein A apparently results from nonspecific aggregation of the amphiphilic "heavy" form of the enzyme. The origin of the apolipoprotein B-GGT complexes found in cholestatic patients needs further investigation.

Both paper and author (D. R. McNeil, (1968)) will be referred to below as DRM. The said paper deals with the following situation: an intersection is controlled by a traffic light with a fixed cycle time, T; the possibility of other delays, e.g., due to turning vehicles, is ignored; arrivals at the light form a compound Poisson process; if vehicles arrive to find the light green and the queue empty they are not delayed, while in the contrary case they depart when they reach the head of the queue, providing the light is green, each vehicle taking a constant time to move off. The length of the effective red period is R. For further details and discussion, DRM may be consulted.

The development of silicon carbide technologies has allowed for the development of sensors and electronics to measure the changes in a variety of hostile environments. A problem has been identified with reliable and efficient ways to power such sensors in these hostile environments. It is likely to be impractical to run power cables to these sensors and battery power has a finite lifetime. Recent research has demonstrated many energy scavenging techniques but to date none have been developed with a view of operation in hostile environments. To investigate the power density achievable from a SiC based energy scavenging device a SiC pin diode was exposed to both broad spectrum light form a tungsten halogen bulb and a 255 nm UV source. IV and CV measurements were used to determine the structural properties and photovoltaic response of the device, dark saturation current, induced photo current and the fill factor. We present the characteristics and maximum power density of these devices at temperatures between 300 K and 600 K. We demonstrate that the maximum power density achievable decreases with temperature. This is mostly due to the reduction in the built in potential from the pn junction, and the reduction of the generated photocurrent.

This paper critiques enlightenment notions of representation and rehearses an alternative model of mapping that is grounded in performance. Working from her own practice as a landscape painter, Bolt argues that the particular experience of the “glare” of Australian light fractures the nexus between light, form, knowledge, and subjectivity. This rupture prompts a move from shedding light ON the matter to shedding light FOR the matter and suggests an emergent rather than a representational practice.
