The performance and mechanism of virus removal by microfiltration with coagulation pretreatment were investigated. We confirmed the unexpectedly high performance of virus removal for two types of ceramic membrane system: a positive pressure-driven dead-end filtration with inside-out configuration and a vacuum pressure-driven dead-end immersed filtration with outside-in configuration. Virus removals by both systems were more than 7 logs, although the size of the tested Qβ virus (23 nm) was much smaller than the membrane nominal pore size of 100 nm. The virus inactivation by the addition of the coagulant (PACl) and the virus adsorption onto the floc retained on the membrane surface mainly contributed the virus removal. No virus accumulation in the retentate was observed, possibly due to the virus inactivation by the coagulant.

Hortus Conclusus

In Lewis’ transposition of Milton’s Paradise to a distant world where Adam and Eve do not succumb to Satan, the structure of Eden is radically different from the enclosed garden familiar to most readers. In the novel Perelandra (1944), C.S. Lewis represents the Garden of Eden as an open and ‘shifting’ place. The new Garden of Eden, with Adam and Eve unfallen, is a place of indeterminate future, excitement, growth, and change, very unlike the static, safe, enclosed Garden—the hortus conclusus of traditional iconography—from which humanity is not just expelled but also, in some sense, escapes. The innovation is not in the theological underpinnings that Lewis claims to share with Milton but in the literary devices that make evil in Perelandra seem boring, dead-end, and repetitive, while goodness is the clear source of change and excitement.

The literary career and troubled life of Derwent Moultrie Coleridge (1828–80), Derwent Coleridge's eldest son (S. T. Coleridge's first grandson) has been critically overlooked. After a period of alcohol-related, reckless behaviour at Cambridge University, he was exiled to Australia in November 1850, lest he continue to dishonour his father and the Coleridge name. Despite struggling considerably, he quickly became part of an Australian literary circle and he often contributed poems to Sydney newspapers. This essay analyses the most biographical of his poems that was published in the Australian press, ‘The Loafer's Christmas’ (1871) – a hitherto unknown poem – looking, in particular, at the dialogues in which the poem engages with his family, especially S. T. Coleridge's ‘The Rime of the Ancient Mariner’. I also contextualise ‘The Loafer's Christmas’ within nineteenth-century Australian culture. Looking at issues of exile, idleness, addiction, family, home(lessness), and religious redemption, this essay explores the ways in which Derwent Moultrie's exile proved to be both a literary liberation and a dead end, trapping him between times and spaces, real and imaginary. In so doing, I show how the lost life and writings of Derwent Moultrie Coleridge can offer us new perspectives on the Coleridge legacy.

Reporting Data

Rabies remains a constant threat to humanity in many parts of the world. At the same time, scientifically grounded antiepizootic measures should be based on the peculiarities of the regional epizootology of this zooanthroponosis. The authors studied the epizootological and statistical reporting data of the Kropotkin Regional Veterinary Laboratory, presented an analysis of the registration of rabies in animals in Krasnodar region. From the obtained data, it should be noted that despite the wide range of animals involved in the epizootic process of rabies infection in Krasnodar region, dogs, cats and foxes play a major role in the reservation and spread of infection, which account for 78.6. Of the total number of registered cases, 15.5% falls on foxes, that indicates the natural focus of the disease, along with the manifestation of the disease in an urban form. At the same time, stray and neglected dogs and cats, which occupy a significant place among the total number of sick animals, are also sources and spread of the infection. Thus farm animals (8.3% of the total number of infected animals) are a biological dead end for the infection. Isolated cases of the disease were noted in muskrat, donkey, raccoon, raccoon dog, marten, ferret and jackal. The authors also established the specific morbidity of various animal species with rabies infection, that is an important aspect in the development and implementation of antiepizootic measures complex
