Hydrogen Fire Detection System Features Sharp Discrimination

Hydrogen fire detection system discovers fires by detecting the flickering ultraviolet radiation emitted by the OH molecule, a short-lived intermediate combustion product found in hydrogen-air flames. In a space application, the system discriminates against false signals from sunlight and rocket engine exhaust plume radiation

Discourse and identity in a corpus of lesbian erotica

This article uses corpus linguistic methodologies to explore representations of lesbian desires and identities in a corpus of lesbian erotica from the 1980s and 1990s. We provide a critical examination of the ways in which “lesbian gender,” power, and desire are represented, (re-)produced, and enacted, often in ways that challenge hegemonic discourses of gender and sexuality. By examining word frequencies and collocations, we critically analyze some of the themes, processes, and patterns of representation in the texts. Although rooted in linguistics, we hope this article provides an accessible, interdisciplinary, and timely contribution toward developing understandings of discursive practices surrounding gender and sexuality

Bioremediation in prawn grow out systems - Winter school on recent advances in diagnosis and management of diseases in mariculture, 7th to 27th November 2002, Course Manual

In any aquaculture systems there exist a continuous exchange of substances between the bottom sediment and the overlying water, and between the two and the reared animal body. This exchange is strongly influenced by the inputs made continuously in to the system. As a matter of fact the bottom soil conditions and water quality in ponds are very much closely interrelated. Obviously, the water quality in ponds is very much influenced by the nutrient inputs, organic matter content, primary productivity and dissolved oxygen. Any aquaculture system has a finite capacity to assimilate nutrients, organic matter and the byproducts of degradation to a level congenial for the animals to grow. Bioremediation aims at the maintenance and enhancement of this finite capacity of the pond in favour and well being of the stock. Bioremediation in principle use microorganisms to transform/ decontaminate toxic pollutants in the environment. The process has two basic methods I. Bioaugmentation. 2. Biostimulation. One of the main concerns of bioremediation is that the degradation products, whatever it may be, should be non toxic to the stocked animals. Major advantages of bioremediation are I. It can be done on site (in-situ) 2. The process does not lead to any site disruption, 3. There is every possibility for permanent waste elimination, 4. Being a biological process it will be comparatively too inexpensive and 5. Can be effectively coupled with other treatment technologie

Regional Economic Implications of Water Allocation and Reliability

The understanding of how allocation decisions can maximise the economic returns to the community from water for irrigation has received little attention, but is a significant issue for regional councils, those interested in water allocation policy development, and for irrigated farmers. There is a tradeoff between the amount of irrigated area and the reliability with which it can be undertaken. Overseas studies have generated a curve with optimum levels of allocation which maximise the economic return to the community from the resource. The study on which this paper is based used a single case study to model the individual and regional economic outcomes for four scenarios of water allocation, using daily time step simulation models of the hydrological, irrigation, farm and financial systems over the 1973 – 2000 period. The results show that there is an increasing return to the region as the allocation from the resource increases, at the expense of lower returns to existing users.Irrigation, reliability, regional economic impacts, Agribusiness, Agricultural and Food Policy, Agricultural Finance, Community/Rural/Urban Development, Environmental Economics and Policy, Farm Management, Financial Economics, Institutional and Behavioral Economics, Land Economics/Use, Resource /Energy Economics and Policy,

How advertising campaigns can help to mitigate the negative effects of voter ID laws on turnout.

A majority of American states have instituted some form of voter ID law, laws which have been found to reduce turnout for poor and minority populations. In new research Michael S. Lynch and Chelsie L.M. Bright examine the introduction of Kansas’ recent voter ID law. They find that in one county, the distribution of materials reassuring voters about provisional ballot procedures and efforts to make voter ID easier to obtain, meant an increase in turnout compared to other precincts

Increasing security of supply by the use of a local power controller during large system disturbances

This paper describes intelligent ways in which distributed generation and local loads can be controlled during large system disturbances, using Local Power Controllers. When distributed generation is available, and a system disturbance is detected early enough, the generation can be dispatched, and its output power can be matched as closely as possible to local microgrid demand levels. Priority-based load shedding can be implemented to aid this process. In this state, the local microgrid supports the wider network by relieving the wider network of the micro-grid load. Should grid performance degrade further, the local microgrid can separate itself from the network and maintain power to the most important local loads, re-synchronising to the grid only after more normal performance is regained. Such an intelligent system would be a suitable for hospitals, data centres, or any other industrial facility where there are critical loads. The paper demonstrates the actions of such Local Power Controllers using laboratory experiments at the 10kVA scale

Use of immunostimulants in aquaculture management - Winter school on recent advances in diagnosis and management of diseases in mariculture, 7th to 27th November 2002, Course Manual

Immunostimuiant may be defined as an agent, which stimulate the non-specific immune mechanism when given alone, or the specific immune mechanism when with an antigen. Immunostimulants activate the immune system of animals and render them more resistant to infections by viruses, bacteria, fungi and parasites. They may also be active against human cancer because they activate white blood cells, which recognize and destroy tumor cells. Immunostimulants are valuable for the control offish diseases

Ornamental fish diseases and their management measures- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

Aquarium fish industry constitutes an extremely large segment of the pet animal industry. Over two decades, there experienced progressive increase in the ornamental fish industrial productivity both in the domestic market and at International level. Than ever before, more and more indigenous as well as exotic varieties of fishes are being registered into the trade. Primarily being aquatic animals and secondarily being forced to remain under crowded conditions, they are subjected to diseases of varying nature

Integrity, ethical leadership, trust and work engagement

PURPOSE– The purpose of this paper is to investigate how leader integrity and ethical leadership can influence trust in the leader and employee work engagement. DESIGN/METHODOLOGY/APPROACH– Data were collected using an electronic web-based questionnaire completed by 204 employees from various business organisations. Data were analysed by means of item analysis and confirmatory factor analysis conducted via structural equation modelling. FINDINGS – High levels of reliability were found for the measurement scales. Good model fit was demonstrated for the measurement and structural models. Empirical support was found for all the postulated relationships in the structural model. ORIGINALITY/VALUE – This study is the first to analyse the joint relationships between leader integrity and work engagement through the mediating role of ethical leadership (i.e. moral management) and trust in the sise the key role played by ethical leaders in creating an ethical and trusting work climate conducive for employee engagement.IS
