Aquatic Resources in Foodcrusts: Identification and Implication

Heron, Carl P., Craig, O.E. January 2015 (has links)
No / Foodcrusts, the charred surface deposits on pottery vessel surfaces, provide a rich source of data regarding container function. This article reviews recent applications focusing on the detection of aquatic resources (marine and freshwater) in pottery vessels using a range of analytical approaches including bulk isotope measurements of carbon and nitrogen, lipid biomarker analysis, and compound-specific carbon isotope determinations. Such data can help to evaluate the presence of reservoir effects when undertaking radiocarbon dating of foodcrust samples. In particular, molecular and isotopic analysis can aid in the selection of suitable candidates for C-14 where it can be demonstrated that aquatic resources are unlikely to contribute to the residue. Prospects for compound-specific C-14 analysis of lipids in foodcrusts and ceramic-absorbed residues are also discussed.

Supply Chain Oriented Integrated Tactical Planning Method For Intercontinental Rail Freight Transport

Shan, Jing 29 October 2024 (has links)
This thesis addresses integrated challenges within the global supply chain and intercontinental rail freight transport, establishing the foundation for a new research area. First, this thesis focuses on the development of unified SCOR-Rail Key Performance Indicators (KPIs) for intercontinental rail freight transport, as well as initial analysis on Eurasian rail freight. It also proposes various rail supply chain strategies to differentiate rail services, including efficient, continuous replenishment, and responsive rail supply chain strategies that support market segmentation and service differentiation. The proposed Integrated Tactical Planning Method (ITPM) is a supply chain-oriented planning approach for intercontinental rail freight transport. It considers the intercontinental rail freight network's complexities, such as multiple border crossings and transshipments at border crossing terminals, the unique characteristics of different train lengths across different rail systems, as well as multiple stakeholders such as terminals, railway undertakings, infrastructure providers, and shippers and forwarders. ITPM offers optimization models (I-FSND and I-SSND) that simultaneously account for both the supply chain and rail system sides. Both models simulate the complexities of intercontinental rail freight operations. The I-FSND model calculates the train service frequency on each route during the planning period, whereas the I-SSND model considers the synchronization of each order at border-crossing terminals across different rail systems. Furthermore, both models include a rejection mechanism and consider transit time differences on the same arc for the main transit, with the I-SSND model determining the duration time of each order at terminals. In the I-FSND model, a weighted goal programming method optimizes resource allocation, balancing service quality, profit, total number of accepted containers through the network, and border crossing terminals' capacity deficiency. The potential capacity deficiencies—information is useful when making future investment decisions. The ITPM is a powerful tool for intercontinental rail freight planners, the proposed optimization models I-FSND and I-SSND ensure more efficient utilization of resources while simultaneously satisfying heterogeneous transport service requirements of the supply chain. Rail planners can employ the I-FSND model for network capacity analysis across various scenarios, especially when the specific timetable of train services is not a primary concern, while I-SSND model could be used to more operational analysis. Furthermore, ITPM is not only applicable to intercontinental rail freight, but also to rail freight transport networks with multiple border crossings, such as the Trans-European Transport Network (TEN). The initial application of these models in Eurasian rail freight shows promising potential for broader implementation in intercontinental rail freight transport, particularly in creating new business opportunities to meet the diverse transport demands of the supply chain.:1 Intercontinental rail freight transport 1 1.1 Motivation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Potrava vydry říční (Lutra lutra) v závisloti na vysazení potoční formy pstruha obecného (Salmo trutta m. fario) a lipana podhorního (Thymallus thymallus) / Diet of Eurasian otter (Lutra lutra) in relation to the stocking of brown trout (Salmo trutta m. fario) and grayling (Thymallus thymallus)

Lyach, Roman January 2014 (has links)
This study aimed to evaluate otter predation on stocked trout and grayling. The diet composition of piscivorous Eurasian otters (Lutra lutra) was studied on the stream Chotýšanka in central Bohemia using spraint (otter faeces) analysis during one winter period (90 days). Stocking took place mostly in the second half of 2005. Around 5000 hatchery-reared brown trouts (Salmo trutta m. fario) of size about 10 cm, 600 graylings (Thymallus thymallus) of the same size and 480 rainbow trouts (Oncorhynchus mykiss) of size about 30 cm were stocked into the stream. Spraints were collected in December 2005 and January 2006. We found and identified 1531 fish in the spraints. The primary food source of otters was fish (almost 85 % of biomass). The main fish prey was small - sized, below 20 g in weight and 13 cm in length. The bulk of otter's diet consisted of less - valued species, especially the gudgeon (Gobio gobio). Other frequently consumed fish species were the European chub (Squalius cephalus), the common carp (Cyprinus carpio), the European perch (Perca fluviatilis), the brown trout and the rainbow trout. Consumption of stocked brown trout was 1,80 %, while cosumption of stocked rainbow trout was 10,90 % of biomass. Otters in this area consumed about 723 - 1446 brown trouts and 72 - 144 rainbow trouts...

The Influence of Chinese Folk and Instrumental Music on Tcherepnin's "Chinese mikrokosmos": A Lecture Recital, Together with Three Recitals of Selected Works of J.S. Bach, W.A. Mozart, C. Debussy, S. Rachmaninoff, D. Shostakovich, and Others

Luo, Yeou-Huey 08 1900 (has links)
One of the most important compositional theories of Alexander Tcherepnin (1899-1977), Russian-American composer and pianist, is the Eurasian ideology, which was a result of the influence of Eastern culture. Inspired by this theory, Tcherepnin not only extricated himself from his own compositional techniques, but also intensified his search for musical folklore. In April, 1934, he began a world tour which was to include China, Japan, Singapore, the Philippines, Egypt, and Palestine, to search for "musical folklore." He became so fascinated with the culture of ancient China that he cancelled the rest of his arrangements, and, except for visits to Japan, he remained in China for three years, until the outbreak of the Sino-Japanese War in July, 1937. During his three-year stay in China, Tcherepnin was greatly attracted to Chinese culture, and as a result, Chinese culture influenced his music to a significant degree. This essay examines the manner in which Tcherepnin's music was influenced by his experiences in China. In order to precisely analyze the close affiliation between Chinese musical elements and Tcherepnin's "Chinese Mikrokosmos," many original Chinese sources proved indispensable in this study. These sources include Chinese folk music, theater music, instrumental music, religious music, and Chinese periodicals and newspapers that reported Tcherepnin's activities in China (1934-7). The organization of this dissertation as follows: Chapter I provides a brief biographical sketch of Tcherepnin, traces his activities in China, and introduces one of his greatest "Chinese" compositions, "Chinese Mikrokosmos," which represents the fruits of his labors to scrutinize and absorb Chinese musical language. Chapters II and III are devoted to exploring how Chinese folk and instrumental music inspired Tcherepnin's "Chinese Mikrokosmos." Chapter IV summarizes this study.

Vliv UV složky spektra na odmítání parazitických vajec rákosníkem obecným (Acrocephalus scirpaceus) / The role of UV reflection in parasite egg rejection in reed warbler (Acrocephalus scirpaceus)

Šulc, Michal January 2012 (has links)
One of the best ways how hosts may defend their clutch against brood parasitism is recognition and rejection of parasitic eggs. It has been documented that ability to percept UV light in birds affects their behaviour. By using a spectrophotometer we found that Reed Warbler (Acrocephalus scirpaceus) eggs and Common cuckoo (Cuculus canorus) eggs differ mainly in brightness but also in UV hue. We investigated the influence of birds' UV vision on recognition and rejection of parasitic eggs. Therefore we performed three experiments to reveal the role of eggshell UV reflectance on egg rejection in this host. In the first experiment, we parasitized clutches with artificial white eggs differing only in UV reflectance (UV- and UV+). In the other two, we experimentally reduced UV reflectance from conspecific and host own eggs. We used a UV light blocker, which did not influence the reflectance shape in the other parts of spectra. As a control we used a group of conspecific and own eggs coated in Vaseline, which did not affect eggshell reflectance. In each experiment, we monitored host response to parasitic eggs. Because the Reed Warbler's eggs reflect UV radiation themselves, we expected that white UV- eggs would be rejected as well as the eggs coated in UV blocker at a higher rate than white UV+ eggs and...

Armenia's accession to the Customs Union : gains of losses?

Ghazaryan, Sevan January 2014 (has links)
Armenia is going to join the Customs Union of Belarus, Kazakhstan and Russia (the Eurasian Customs Union) in the coming months. The author uses partial-equilibrium model to investigate and calculate trade diversion, trade creation and net welfare effects of accession on the Armenian economy. The thesis concludes that the membership in the customs union would lead to welfare losses and negative static effects. The main reason is the pure trade diversion effect on Armenia resulting from the increased external tariff rate. Adopting the common external tariff of the Eurasian Customs Union would raise the prices of those imported goods which flow from outside the customs union. As the majority of Armenian imports come from outside the Eurasian Customs Union, the increase in import prices would carry high social costs for the Armenian consumers. In addition, the absence of shared border with the customs union member-states substantially diminishes the potential benefits from possible non-tariff barrier facilitation. Therefore, the thesis strongly recommends against the accession.

Decolonising Anglo-Indians : strategies for a mixed-race community in late colonial India during the first half of the 20th century

Charlton-Stevens, Uther E. January 2012 (has links)
Anglo-Indians, a designation acquired in the 1911 Indian Census, had previously been known as Eurasians, East Indians, Indo-Britons and half-castes. ‘Anglo-Indian’ had previously denoted, and among some scholars continues to denote, Britons long resident in India. We will define Anglo-Indians as a particular mixed race Indo-European population arising out of the European trading and imperial presence in India, and one of several constructed categories by which transient Britons sought to demarcate racial difference within the Raj’s socio-racial hierarchy. Anglo-Indians were placed in an intermediary (and differentially remunerated) position between Indians and Domiciled Europeans (another category excluded from fully ‘white’ status), who in turn were placed below imported British superiors. The domiciled community (of Anglo-Indians and Domiciled Europeans, treated as a single socio-economic class by Britons) were relied upon as loyal buttressing agents of British rule who could be deployed to help run the Raj’s strategically sensitive transport and communication infrastructure, and who were made as a term of their service to serve in auxiliary military forces which could help to ensure the internal security of the Raj and respond to strikes, civil disobedience or crises arising from international conflict. The thesis reveals how calls for Indianisation of state and railway employment by Indian nationalists in the assemblies inaugurated by the 1919 Government of India Act threatened, through opening up their reserved intermediary positions to competitive entry and examination by Indians, to undermine the economic base of domiciled employment. Anglo-Indian leaders responded with varying strategies. Foremost was the definition of Anglo-Indians as an Indian minority community which demanded political representation through successive phases of constitutional change and statutory safeguards for their existing employment. This study explores various strategies including: deployment of multiple identities; widespread racial passing by individuals and families; agricultural colonisation schemes; and calls for individual, familial or collective migration.
