Lime Production

AbstractBurnt lime has played a significant role in daily Maya life since at least as far back as 1100 b.c., and yet its ephemeral nature has limited archaeological studies of its production. The application of new surveying and remote sensing technologies in recent decades is now allowing for a more in-depth investigation of the burnt lime industries that existed in different subregions of the Maya area. This article provides an overview of the current understanding of pre-Hispanic Maya burnt lime production. It then presents an analysis of the factors influencing the development and identification of distinct subregional lime production industries, including: lime consumption requirements and inter-site spacing; natural environment; local social and economic trajectories; and the objectives and survey universes of archaeological investigations. In reporting the tremendous advances made over the past few decades, this paper encourages archaeologists to include a focus on identifying lime production features in their research agendas.

Lime Production

We have examined 5 different limestones in order to study their behavior i) during calcination at different temperatures (900, 1050 and 1200°C for 30 min) and ii) after hydration of quick limes derived to slaked lime. Quick limes calcined at 900°C show the lower reactivity values. This could be related to the low calcination temperature or to the short calcination time of 30 min which was unable to produce enough lime. The samples calcined at temperatures of 1200°C are less reactive compared to the hydrated limes which were prepared by hydration of quick lime calcined at 1050°C, indicating by parameters such as the (CaO+MgO)Lime, the time required to become the temperature maximum and the reactivity rate. These, probably could be due to crystal growth at relative high temperatures.

The article considers the approaches to building a circular economy based on the example of a functioning Russian industrial hub. Among the features analyzed are the specificities of the industrial symbiosis development of chemical enterprises and material flows that link different technical processes, namely the production of soda ash, lime, salt, and gypsum. This study assesses the pollutant emissions from the new technical processes and the use of accumulated chrome production wastes as secondary material resources. Likewise, the article demonstrates the possibility of direct absorption of carbon dioxide, as a byproduct of lime production during soda ash manufacturing. The study ends with recommendations for considering the aspects for the use of secondary resources in determining the sectoral and inter-sectoral best available techniques. Similarly, it sheds light on possibilities for optimizing the system of technological regulation and general binding rules application for managing insignificant environmental aspects of industrial production.

USING MULTIPLE LINES OF EVIDENCE TO IDENTIFY PREHISPANIC MAYA BURNT-LIME KILNS IN THE NORTHERN YUCATÁN PENINSULA

Lines Of Evidence

This study discusses the investigation of a series of pit-kilns in and around the prehispanic site of Kiuic in the Puuc region of the northern Maya lowlands and presents the multiple lines of evidence that identify these structures as lime production features. The study reports the results of systematic excavations, archaeometric analyses, archaeological experiments, ethnographic inquiries, and spatial analyses. Burnt lime has been used for architectural, dietary, hygienic, and other purposes by the Maya for at least three millennia and yet its importance in prehispanic Maya society is belied by the lack of lime production features identified in the archaeological record. The identification of these structures as lime production features has implications for understanding subregional differences in socioeconomic organization and resource management practices among the prehispanic Maya. This report provides a model for using multiple methods and analyses to investigate and identify lime production kilns that can be applied to societies and landscapes throughout the Maya area and the broader premodern world.

Abstract In 2010 burnt lime blocks were accidentally mixed with limestone concrete aggregates at a Belgian limestone and lime production plant. The contaminated limestone aggregates were used in precast concrete factories. The concrete elements used in several constructions quickly showed pop-outs, caused by swelling of lime nodules. The appearance of pop-outs in suspected constructions was recorded. An extensive experimental program as well as on site observations have been made, to monitor the evolution of the pop-out phenomenon with time. The pop-out evolution in outside exposure conditions is compared to the evolution of pop-outs under inside climatic conditions. Outside, the phenomenon becomes marginal after about 2 years. In inside exposure conditions, the phenomenon still continues after 7 years, be it at a low rate.

The 1960S

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.
