The presence of oil shale near The Narrows between Rundle Range and Curtis Island, Queensland, has been known for many years, although the only previous efforts at evaluation of the deposit were during World War II by the Queensland Mines Department and subsequently by Carpentaria Exploration Company in 1969-70. The price increase of oil from OPEC sources has once again made oil shale a possible alternative energy source.Core drilling over the past two years in a relatively restricted area near The Narrows by Southern Pacific Petroleum NL and Central Pacific Minerals NL (2330 m in 19 holes) suggests the persistence of oil shale beds over a strike distance of 7 km with a width of 1000 to 2500 m and a composite thickness of at least 427 m. What appears initially as a monotonous sequence of shales and mudstones is found to be remarkably constant lithologically across the range of borehole control. Four lithologic units are recognised, three of them with a significant and persistent content of hydrocarbon compounds.Limited chemical and petrographic studies indicate that the sequence mineralogically comprises a mixture of quartz, clay minerals, minor carbonates and varying amounts of kerogen. Ostracods are the most common and persistent fossil form but gastropods and crustacean, fish, reptilian and algal remains occur at intervals. Plant and spore material are present but not common. The age of the sequence is early Tertiary. The faunal assemblage and sedimentary features suggest that the deposit accumulated under quiet, essentially reducing conditions in a fresh water lake. In the region of borehole control, the sequence dips to the southwest and west at from 4° to 10° apparently as a result of minor tectonic adjustments in common with other coastal Queensland Tertiary deposits.Systematic assaying of the oil shale at Rundle suggests that an average grade of 89 I of shale oil per tonne persists at a waste-to-resource ratio of about one-to-one over an area of 1400 hectares. While in-fill drilling is needed to confirm these figures, the dimensions of the resource indicated is at least 1200 million tonnes of oil shale which contains the equivalent of 600 million barrels of oil in this area. Further exploration drilling will probably indicate an extension of the deposit.

Research on solarthermal processing and the need for alternative energy sources have reached the point where efforts to develop some industrial processes and expand research to suggest others are at least desirable, if not imperative. This paper presents a rationale for such an effort, describes the underlying thermodynamics, and summarizes much of the research which has been conducted in the years since the end of World War II. Major emphasis is placed on the work that has been done since the imposition of the 1973 oil embargo and the present.

Europe went back to war in 1939 and on July 19 1940, the U.S. Congress passed the Two-Ocean Navy Act, the largest naval appropriation in American history, which expanded the U.S. Navy by more than seventy per cent in preparation for the United States entry into the war. ‘The two-ocean navy: the U.S. Navy in World War II (1939–1945)’ outlines the key battles fought by the U.S. Navy: in the Pacific from 1941–43, in the Mediterranean from 1943–44, the Central Pacific drive from 1943–44, the D-Day landings in 1944, and the ferocious battles with the Japanese at Iwo Jima and Okinawa that ended the war.

Soldiers, sailors, airmen, and marines have strong opinions on how the Pacific War was fought and how victory was achieved over Japan. Too often these views have been shaped by service parochialism dressed up in the guise of war principles. Regarding the issue of unity of command, there was actually more unity in the Pacific theater than there was in Europe. Strategy is similarly seen through parochial lenses and usually breaks into three camps: sailors and sea power advocates trumpet the importance of the Central Pacific thrust commanded by Admiral Chester Nimitz. Soldiers and land warfare historians instead hail General Douglas MacArthur’s island-hopping campaign in the Southwest Pacific Area. Airmen applaud the strategic bombing campaign culminating in the atomic bombs. In truth, it was a joint effort by all the services that defeated Japan.

The deployment of United States (US) Armed Forces personnel into the central Pacific islands of Samoa and Tonga, which is highly-endemic for lymphatic filariasis (LF), resulted in thousands of cases of the acute form of this disease and greatly reduced their ability to carry out their mission. The major driving factor for the intensity of transmission was the aggressiveness and efficiency of the Aedes species mosquito vectors, especially the day-biting Ae. Polynesiensis. The paper reminds us of the danger that tropical diseases can pose for troops sent into endemic areas and constant and careful surveillance that is required to prevent rapid resurgence of Aedes-transmitted LF in populations, where the LF elimination program has been successful.

Artiklis on vaadeldud Narva ja Sillamäe linnast inspireeritud kirjandust ja üht mängufilmi, mis tegelevad lähemalt maastikuloomega ning kohamälu tekitamisega pärast II maailmasõda. Sõjajärgse Kirde-Eesti ülesehitamine tööstuspiirkonnana on peegeldunud memuaristikas, tagasivaatelistes omaeluloolistes tekstides ning oma kaasajas ehitust kajastavates allikates. Vaadeldud näited avavad seda, kuidas on kirjeldatud nõukogude perioodi tööstuslinna, alustades sõjajärgsest taastamistööst ning lõpetades Andrei Hvostovi tagasivaatega nõukogudeaegsele lapsepõlvelinnale. Tekstide analüüs võimaldab märgata sõjaeelse maastiku transformeerumist tööstusmaastikuks, selle kajastuste vastuolulisust ning sõltuvust kirjutamisajast.   The article observes literary depictions of two towns in North-East Estonia, Narva and Sillamäe, both of which were reconstructed as industrial towns after World War II, in fiction, life writing and a film script, as well as in a feature film made on the basis of the latter. The texts are simultaneously engaged in the making of landscape and creation of local memory after the region’s dramatic change caused by the war. Ida-Virumaa became an industrial region in the second half of the nineteenth century; the Kreenholm Textile factory was one of the world’s largest by the end of the century. In 1916, industrial mining for oil shale was started in North-East Estonia. Oil shale was a strategic resource in World War II as well. In 1944, with the second occupation of Estonia by the Soviet Union, uranium mining was started as a secret object of interest for the military industry. The historical town of Narva was almost completely destroyed in World War II. Few buildings were restored, while the city was filled with blocks of flats typical of the Soviet period and the historical street network was transformed significantly. Still, Narva did not become a utopian Stalinist city – in Estonia, the only example of the latter is Sillamäe, a closed city built according to an all-Union standardised project, that attempted to embody an image of Communist happiness. Postwar literary depictions of Narva have often proceeded from the baroque city centre that has become a separate symbolic site of memory. In the more recent past, different genres have started to complement one another, different periods have been compared and, as a result, representations of various spaces have received a more analytic artistic treatment that connects the pre-war period with the post-war one. The first set of texts discussed here consists of POW memoirs of the immediate post-war reconstruction works, set down some decades later. After that, contemporary reflections of the reconstruction in Soviet Estonia in the 1950s-1960s are considered. Finally, attention is paid to texts that comment on the reconstruction era from a larger temporal distance: a backward look at Soviet-time Sillamäe from 2011 (expanded edition 2014) by Andrei Hvostov, a journalist with a degree in history, who spent his childhood in the town. Hvostov’s memoirs and his short stories on similar topics that were published earlier serve as attempts at parallel interpretations of several possible local memories. A work that in a way unites all three periods is Vladimir Beekman’s novel The Narva Waterfall (1986). Its protagonist Stiina was born and grew up in Narva, left the war-ravaged city and criticises harshly the changes that have taken place in the city. The examples of memoirs, retrospective autobiographical texts and sources reflecting their contemporary period also reveal how industrial cities of the Soviet era have been depicted in different periods. An analysis of the texts discloses the transformation of the prewar landscape into an industrial one, the contradictory nature of its descriptions, as well as dependence of the latter on the time of writing. Examples are given of the possibilities of representing large-scale industrial constructions that significantly also involve not just the creation of new values but also the way of doing this – reflecting the work of the udarniki of the Young Communist League. According to Katerina Clark’s typology of Stalinist novels, one of the texts observed, the film script concerning the shock workers’ building of the Balti Thermal Power Plant to which the youth from the Young Communist League contributed, can be categorised as the most widespread and ritualised type of Soviet fiction, the so-called production novel. The selection of texts discussed in the article is by no means exhaustive and the Ida-Virumaa region may offer fruitful material for future studies using the categories of space and memory, both as regards ways of describing a real region in literature as well as analysing the stories clustered around a site of memory. The notion of a literary city emerging in the texts is broad, as areas and objects with different functions form part of it. The observed texts display an interesting conflict in spatial memory: a deliberate loss of memory induced during a certain period and the creating of something new as if into a void can be emphasised as can be using rhetorical devices to bring forth a new spatial representation, a site of memory in its own right.
