There are many U.S. health-related standards for ozone that aim to limit exposure to ozone. The potential for ozone emission from electrically connected air cleaners is well- known and has led to standards and regulations for portable indoor air cleaning devices, which emit ozone at measured rates of 0.056 – 13.4 mg/hr. However, there is evidence that some in-duct air cleaners may actually emit more ozone than portable air cleaners, despite being exempt from most regulations due to the lack of a suitable test method for measuring ozone generation. To explore if in-duct cleaners actually do emit ozone, I investigated seven commercially available residential in-duct air cleaning devices. These devices used one of two broad technologies as means of air cleaning: UV light or electrical corona. The lowest measured emission rates came from two air cleaners that utilized UV light technology and were 0.309 ± 1.7 mg/hr, which was likely below the detection limit of the apparatus and method, and 4.29± 1.5 mg/hr. Three of the air cleaners tested, also with UV lamps, were of the same brand and model yet exhibited differing emission rates, ranging from 7.44± 1.6 mg/hr to 15.8± 2.6 mg/hr. These three air cleaners were classified as medium emitters and also utilized UV light technology. The high median measured emission rates were measured from both an air cleaner utilizing electrical corona technology, 30.2 ± 4.0 mg/hr, and UV light technology, 29.4 ± 3.9 mg/hr. These experimental results confirm that some in-duct air cleaners are able to generate more ozone than some portable air cleaners and also suggest potential health risks to the indoor environment. / text

Tūkstančiai pabėgėlių, kurie Antrojo pasaulinio karo pabaigoje užplūdo Vakarų Europą, prieglobstį surado Vokietijoje, suskirstytoje į karą laimėjusiųjų sąjungininkų zonas. Jose buvo įkurtos DP stovyklos, kuriose jie gyveno ketverius metus. Be tėvynės likusiais žmonėmis rūpinosi tarptautinės organizacijos – UNRRA bei IRO. Jos pabėgėliams teikė būtiniausią paramą: globą, įkurdinimą ir maitinimą. Stovyklose susibūrus didesniam skaičiui lietuvių, imtos steigti tautinei bendruomenei svarbios institucijos ir prasidėjo intensyvus kultūrinis bei visuomeninis gyvenimas. Visas DP laikotarpio lietuvių gyvenimas buvo tam tikras nepriklausomos Lietuvos laikų gyvenimo modelis. Darbo tema yra Visuomeninio ir kultūrinio gyvenimo refleksija išeivijos laikraštyje „Žiburiai“ 1945-1949 m. Tarp gausių lietuviškos spaudos leidinių išsiskyrė katalikiškos orientacijos laikraštis „Žiburiai“. Jame buvo pristatytas nepriklausomos Lietuvos kultūrinis ir visuomeninis gyvenimas bei svarbiausi istoriniai įvykiai. Šie straipsniai rodė bandymą išsaugoti nenutrūkstamus ryšius su tėvyne. Kuriantis švietimo sistemai, „Žiburiuose“ raginta vadovautis nepriklausomos Lietuvos mokyklų mokymo tradicijomis, o kartu paruošti mokinius gyvenimui svetimame krašte, nepamirštant įskiepyti ir tautinių vertybių. „Žiburiai“ aktyviai dalyvavo ir kultūriniame gyvenime. Literatūros kritikos straipsniuose diskutuota profesionalumo ir mėgėjiškumo, literatūrinės kūrinių vertės temomis, todėl tremties rašytojai įsipareigojo kurti...

DP camps were created in these zones and refugees settled here for four years. Two international organizations named UNRRA and IRO took care of the homeless. These organizations gave the most essential support for refugees such as a custody, accomodation and alimentation. When a greater number of Lithuanians in the DP camps settled, various important institutions for a national community were created, and it was also a significant start for an intense cultural and social life. The whole period of Lithuanian DP life was a particular pattern of a truly independent Lithuanian times. The topic of this work is on The Reflection of Social and Cultural Life in an exile newspaper „Lights“ in 1945-1949. Considering a number of Lithuanian publications, a catholic-oriented newspaper ,,Lights“ was of a great importance among others. In „Lights“ was presented an independent Lithuanian education, culture, most important historical events. These articles demonstrated the try to keep a strong contact with a homeland. While creating a new educational system, „Lights“ encouraged to follow the programmes of an independent Lithuanian learning. It was an attempt to keep the tradition of Lithuanian schools and prepare pupils for a life in a foreign country and not to forget their national values. The „Lights“ actively... [to full text]

The complete thesis in print form is available from the University of Adelaide Library. / With the increasing use of lasers it is necessary to develop materials that can provide protection to eyes and other sensitive devices. This thesis reports on an investigation into optical limiting of Transition Metal Acetylides (TMAs) that transmit ambient light levels of light but block high energy (laser) light across the visible part of the spectrum. A standard optical limiting testbed is used to measure opt~callimiting at 470, 532 and 630 om for a wide range of Pt:ethynyl related TMAs. I report the effect on optical limiting of altering the central bridge, heavy metal, terminal group, solubilising group and oligomerisation. Most of these materials showed poor optical limiting, especially in the red. Two dimers of Pt:ethynyl, however, have clamping levels at 532 om better than that for Pt:ethynyl. I therefore describe a detailed spectroscopic investigation of two series of oligomers and discuss their structure/property relationships. This investigation also includes a precursor ofPtethynyl, PEPE, which shows remarkable limiting. I also report modelling of optical limiting using a 5-level model constructed using the spectroscopic data. I show that the 5-level model can be validated and accurately predicts the limiting for PEPE against both ps and ns pulses. It can also be used to predict ps limiting for Pt:ethynyl and its oligomers. For ns pulses, however, it predicts much less limiting than that observed. I therefore propose a new mechanism that is important for ns limiting by TMAs. Finally I discuss the broadband limiting of these materials and from analysis of the measurements· I describe structures of materials that may show promising broadband optical limiting. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1320307 / Thesis (Ph.D.) -- University of Adelaide, School of Chemistry and Physics, 2008

Abstract Society has changed immensely due to the revolution in information technology. The question is how this technology can be useful to man. My interest lies in how to apply radar to traffic. People in general relate radar to military matters while the focus here is on traffic accidents. Accidents happen and therefore police and ambulance need to be on site as fast as possible. This master thesis presents a new design with hardware and software combined in one device. The combination is essential in traffic technology. I designed a new and smart traffic light that can be effective in a traffic system. I design, discuss and examine the radar up to the laboratory stage. It is based on the Doppler effect and has a sound sensor that can identify a police car and also detect vehicle speed. The status of the traffic lights can then be changed to give priority to the police car, based on speed limits and other restrictions. Difficulties as well as advantages with the design are discussed.
