Salt-accumulating renders are usually applied in several layers with different specific properties of moisture transport. An extensive experimental programme was carried out to establish a relationship between those properties of individual layers and the performance of combined systems on a salt-laden substrate. Each of the 20 renders was characterized separately in absorption and drying tests, vacuum saturation tests, dry cup tests, mercury intrusion porosimetry, and ultrasound wave velocity measurements. Each of the 12 combined render systems was applied on a brick, which was then saturated with a concentrated NaCl solution by free capillary uptake. Subsequently the assembly was closed at the bottom and subjected to an accelerated drying test (50° C and 15% relative humidity). Moisture and salt profiles over the depth were taken regularly during 1 month. The results reveal very different degrees of effectiveness and levels of risk for the substrate, which are related to the moisture transport properties.  相似文献

Saltpetre (KNO3) manufacture was a principal monopoly industry in early Modern India when the United Kingdom governed the social and economic systems. The process represented microbial transformation of excrementitious livestock and human wastes deposited around habitats, resulting in formation of salt efflorescence at an economic scale. Low caste people collected these wastes for extraction and production of rough saltpetre under the administrative control of British India. Stable isotope composition (δ15N and δ18O) was used to trace details of the microbial transformation processes, often involving the isotopic fractionation of nitrogen and oxygen. Marked elevation in δ15N and δ18O values for nitrates in soils and deposits, relative to those of primary organic nitrogen in diets and water sources, characterizes the unique processes of historic saltpetre manufacture in British India.  相似文献

ABSTRACT

The metaphor of catalytic environments adequately accentuates the key role of natural factors in social change without superseding the significance of human agency. In this approach, natural resources are integrated into social practices and strategies while avoiding an environmentally deterministic perspective. The case study of MC-6, Middle Caicos, Turks & Caicos Islands, demonstrates how the natural availability of salt, fish, and cotton affected processes of social change, including settlement practices, food procurement strategies, and long-distance exchange. The inhabitants of MC-6 chose these resources within a social framework of historic practices and regional interaction, while simultaneously depending on local natural conditions and environmental factors. Although environmental diversity in the Caribbean highlights the relevance of catalytic environments, this approach is a tool to examine the dialectic interaction between humans and environments at a global scale.  相似文献

The mounds at Witz Naab and Killer Bee are the only known remaining aboveground evidence of a once-thriving salt industry in Punta Ycacos Lagoon, a large saltwater system in Paynes Creek National Park, Belize. Over one hundred ancient Maya salt works dated to the Classic period (a.d. 300–900) have been submerged by sea-level rise in the lagoon. We have hypothesized that mounds were once numerous features on the landscape prior to a sea-level rise that occurred in the area during the Terminal Classic period. Lacking at these underwater sites are earthen mounds formed by discarded soil from the leaching process in which the salinity of seawater was enriched by leaching brine through salty soil. Enriching the salinity of seawater by leaching or by solar evaporation is virtually universal in ethnographic case studies. Data from the excavations are evaluated to interpret the ancient activities that produced the earthen mounds, scales of production, and how the coastal Maya of southern Belize participated in the larger Classic Maya economy.  相似文献

One of the main factors involved in entheseal changes (EC) aetiology may be related to the physiological limits of biomechanical loading fixed during bone development, such that higher load during childhood and the adolescent growth spurt leads to a lower frequency of EC during adulthood. In this sense, it is possible that ECs may be related to overloading beyond an individual's normal physiological limits as established during childhood and adolescence. This meta‐analysis tested this aetiological possibility by studying the influence of terrain on the entheses of the lower extremities. The hypothesis is that individuals who inhabited rugged terrain have lower EC than those living in flat terrain. This is because biomechanical loads associated with rugged terrain will lead to a higher normal capacity (defined during skeletal development) mitigating the probability of overloading compared to those living in flat terrain who will therefore have a higher frequency of ECs. To test this, papers reporting EC frequencies in the lower limbs were analysed alongside the local terrain. Terrain was defined into two categories: flat or rugged based on altimetry profile, i.e. the average elevation gains and losses along four specific paths (North‐South, East‐West, Northwest‐Southeast, Southwest‐Northeast). Odds ratios were calculated to compare rugged and flat terrain. The overall results are consistent with the hypothesis that overloading is a factor in EC aetiology. However, when the analysis is conducted by sex and side, this general trend does not always occur. Limitations such as the lack of standardized age ranges could be affecting the outcome, i.e. older individuals have a higher frequency of ECs. The findings of this analysis suggest that the theoretical assumptions associated with the cause of ECs require further testing and evaluation. Copyright © 2017 John Wiley & Sons, Ltd.  相似文献

Α new, testable, interpretation of the function of Aegean Early Bronze Age ‘frying pan' ceramics that combines some previously suggested uses is presented experimentally. The proposed function involves a well-documented natural phenomenon responsible for the rapid change in colour of a natural salt marsh or salt pan surface due to the explosive population growth of the extremophile Archaea Halobacterium salinarium when the salt concentration approaches saturation. The cyclical nature of the appearance of red pigmentation on the salt marsh surface every late summer or every few weeks in a domestic ‘frying pan' presents an obvious analogy with the female menstruation cycle and provides an explanation for the fact that several ceramic vessels used for this purpose bear the characteristics of the female body. Furthermore, the resulting red pigment lends itself for use as a cosmetic colorant.  相似文献

ABSTRACT

Analysis of over 4000 complete left oyster valves from late medieval and post-medieval Dudley Castle reveals the changing role of this perishable luxury over a 700-year period. Throughout the occupation, it seems that oysters were used as ingredients rather than served raw in the shell. A greater reliance on oyster consumption is apparent in the later fourteenth century, perhaps reflecting a more diverse diet amongst the aristocracy in the wake of the Black Death. An increased preference for mussels and whelks is also attested in the Tudor and early modern periods, reflecting changing perceptions of these foods.

Overall, it is likely that natural beds were exploited throughout the time that oysters were being brought to Dudley Castle; however, the evidence demonstrates a shift from limited exploitation of natural inter-tidal sources in the eleventh century towards the dredging of sub-littoral beds in later periods, with some possible translocation of oyster stock. Changes in the shape, size and appearance of the oyster shells suggest the source locales from which the oysters derived changed through time. A notable shift occurred in the fourteenth century, which could reflect changes in supply brought about by altered tenancy at Dudley Castle and/or disruptions to trade brought about by the Black Death. Future biochemical analyses are recommended to provide greater clarity on the origin of those sources.  相似文献

Invasive vegetation species can lead to major changes in the geomorphology of coastal systems. Within temperate estuaries in the southern hemisphere, especially Australia and New Zealand, the cordgrass Spartina spp. has become established. These species are highly invasive, and their prolific growth leads to the development of supratidal environments in formerly intertidal and subtidal environments. Here, we quantified the impact of Spartina invasion on the geomorphology and sequestration capacity of carbon in the sediments of Anderson Inlet, Victoria, Australia. Spartina was first introduced to the area in the 1930s to aid in land reclamation and control coastal erosion associated with coastal development. We found that Spartina now dominates the intertidal areas of the Inlet and promotes accretion (18 mm/year) causing the formation of over 108 ha of supratidal islands over the past 100 years. These newly formed islands are calculated to potentially contain over 5.5 million tonnes of CO2 equivalent carbon. Future management of the inlet and other Spartina‐dominated environments within Australian presents a dilemma for resource managers; on the one hand, Spartina is highly invasive and can outcompete native tidal marshes, thereby warranting its eradication, but on the other hand it is likely more resilient to rising sea levels and has the potential for carbon sequestration. Whether or not the potential advantages outweigh the significant habitat change that is anticipated, any management strategies will likely require additional research into costs and benefits of all ecosystem services provided by Spartina including in relation to nutrient cycling, shoreline stabilisation, and biodiversity as well as in response to the longevity of carbon found within the sediments.  相似文献
