Hollywood by Hollywood: the backstudio picture and the mystique of making movies
2019
In comparison with some of its other great genres, what Steve Cohan terms ‘the backstudio picture’ has been relatively unexplored in film studies, though screen fictions that focus on the film indu...
A prequel to Nollywood: South African photo novels and their pan-African consumption in the late 1960s
2010
This article interrogates the history of the photo novel in Africa with particular reference to African Film, a magazine of almost pan-African circulation, published between 1968 and 1972 in South Africa. Featuring the adventures of Lance Spearman, an African crime fighter, the magazine was read widely across Anglophone Africa, from Nigeria and Ghana to South Africa, Zambia, Tanzania, Kenya and Uganda. After a brief introduction to the history of the photo novel, the author discusses the production, content, reception, and legacy of the Lance Spearman photo novels. It is argued that Lance Spearman may be understood as a crossover of James Bond and Philip Marlowe, and several influences from…
Phytochemical Analysis and Cytotoxicity Towards Multidrug-Resistant Leukemia Cells of Essential Oils Derived from Lebanese Medicinal Plants
2012
Juniperus excelsa fruit essential oil as well as J. oxycedrus, Cedrus libani, and Pinus pinea wood essential oils have been obtained with yields between 2.2 ± 0.3 % to 3.4 ± 0.5 % and analyzed by gas chromatography. Sesquiterpenes mainly characterized C. libani and J. oxycedrus essential oils, while in P. pinea and J. excelsa, monoterpenes were the most abundant compounds. In J. oxycedrus, cis-calamenene (7.8 %), cuparene (3.8 %), and cis-thujopsenal (2.0 %) have been detected for the first time. The cytotoxic activity of these essential oils against drug-sensitive CCRF-CEM and multidrug-resistant P-glycoprotein-expressing CEM/ADR5000 leukemia cells has been investigated (IC₅₀ values: 29.46…
Sapropel as a Binder: Properties and Application Possibilities for Composite Materials
2015
Recent development trends largely look for possibilities of a wider use of natural materials and local resources. In this perspective, the use of organic rich lake sediment - sapropel - as a binding material in line with other environmentally friendly filling materials can be considered as a challenge. Sapropel itself is a valuable resource with multiple areas of application, for example, medicine, veterinary, agriculture, livestock farming, balneology, cosmetic applications, construction, and its application options have been widely studied in the 20th century in the Baltic countries, Ukraine and Russia. Birch wood fibre and sanding dust, hemp shives, 'Aerosil' are used as a filler and thr…
Wood-inhabiting fungal responses to forest naturalness vary among morpho-groups
2021
The general negative impact of forestry on wood-inhabiting fungal diversity is well recognized, yet the effect of forest naturalness is poorly disentangled among different fungal groups inhabiting dead wood of different tree species. We studied the relationship between forest naturalness, log characteristics and diversity of different fungal morpho-groups inhabiting large decaying logs of similar quality in spruce dominated boreal forests. We sampled all non-lichenized fruitbodies from birch, spruce, pine and aspen in 12 semi-natural forest sites of varying level of naturalness. The overall fungal community composition was mostly determined by host tree species. However, when assessing the …
Integrating fire-scar, charcoal and fungal spore data to study fire events in the boreal forest of northern Europe
2019
Fire is a major disturbance agent in the boreal forest, influencing many current and future ecosystem conditions and services. Surprisingly few studies have attempted to improve the accuracy of fire-event reconstructions even though the estimates of the occurrence of past fires may be biased, influencing the reliability of the models employing those data (e.g. C stock, cycle). This study aimed to demonstrate how three types of fire proxies – fire scars from tree rings, sedimentary charcoal and, for the first time in this context, fungal spores of Neurospora – can be integrated to achieve a better understanding of past fire dynamics. By studying charcoal and Neurospora from sediment cores f…
Growth form matters – Crustose lichens on dead wood are sensitive to forest management
2022
Lichens have a vital role in forest ecosystems and they are a threatened group in boreal forests. However, the conservation ecology of the total lichen community has very rarely been studied. Here we studied lichen species and communities, including macrolichens (=foliose and fruticose growth forms) and rarely studied crustose li-chens, on decaying wood in boreal spruce-dominated forests in Finland. We also studied obligate lignicoles that grow only on dead wood and are mostly crustose in growth form. Species richness and community composition were examined on decaying logs and natural or cut stumps of Picea abies at different decay stages (2-5) in 14 stands, half of which were natural or s…
Biodiversity of the Sicilian Forests. Part I: the birds
2014
E stata censita la diversita delle specie ornitiche presente in alcune tipologie forestali della Regione Siciliana e la relazione tra le ornitocenosi, le scelte gestionali ed i diversi fattori abiotici e biotici. L’analisi della species richness (= numero delle specie) dimostra che essa e correlata con il bioclima, il diametro massimo degli individui arborei, il valore trofico di tutti gli strati di vegetazione ed il valore trofico dello strato arboreo. I boschi meso-supramediterranei sono piu ricchi di specie rispetto ai boschi termomesomediterranei. L’importanza del diametro massimo degli individui arborei, che esprime indirettamente anche il tipo di gestione di un bosco, viene spiegata d…
Exoten am Lago Maggiore. Die Exkursion
2011
Als Insubrien wird der westliche Teil des oberitalienischen Seenbogens bis in eine Hohe von etwa 500 Meter u. NN bezeichnet. Charakteristisch fur diese Region rund um den Lago Maggiore sind ein mild-feuchtes Klima mit ergiebigen Niederschlagen vor allem wahrend der Vegetationsperiode sowie saure Bodenverhaltnisse. Diese Standortfaktoren fuhren zusammen mit der jahrhundertealten Gartenbautradition zu einer ausergewohnlichen Vielfalt an Geholzen, die sich hervorragend zu Studienzwecken eignet. Auffallig ist vor allem ein hoher Anteil an breitblattrigen, immergrunen Holzpflanzen, wobei die Garten sehr viele exotische Arten beherbergen. Einige davon etablieren sich als Neophyten auch in naturli…
THE SAN VITO WOODEN PULPIT FROM MUSEO DIOCESANO OF PALERMO, ITALY: MULTIDISCIPLINARY APPROACH AND ANALYTICAL TECHNIQUES FOR DATING AND RESTORATION
2017
The aim of the present research is to investigate the constitutive materials and the execution techniques of San Vito wooden pulpit from Museo Diocesano of Palermo (Italy) and to provide helpful information to dating it in addition to technical, historical and artistic evaluations. The pulpit, attributed to unknown artist, belongs to the decorative arts and the most relevant feature is its double dating, in addition to the singular painting technique: it has a linear structure typical of XIXth century and three polychrome and gilded panels probably dated to the end of XVIIth century. This paper describes the application of analytical techniques (imaging diagnostics techniques, Scanning Elec…
