Food Rituals and Their Social Significance in the Mid‐Second Millennium BC in the Southern Levant: A View From Megiddo

Ceremonies involving intentional burial of animals with humans are acknowledged to bear religious, social and political connotations, and we explored both the ritual activity and the social trajectory of these activities. To date, these ceremonies have rarely been examined within the context of nearby daily activities. We studied faunal remains associated with intramural burials in comparison with contemporaneous daily life in the midsecond millennium bc at Tel Megiddo, as well as comparison with concomitant extramural burials and locations of public feasts. Our study highlights the human interaction with animals that are not often treated as bearing social meaning or having interrelationships with human, the livestock animals. We demonstrate that livestock animals in the second millennium bc had a significant social role as well as economic value. The choice of animals consumed and sacrificed in these rituals is strongly related to the animal's symbolic potency and is based on the desired social message that the population aims to convey. Finally, the form of luxury food that is found in the Megiddo funerary rituals supports the hypothesis regarding the intramural burials' role in creating and enhancing social family bonds.

Migration of metamorphic CO2 into a coal seam: a natural analog study to assess the long‐term fate of CO2 in Coal Bed Carbon Capture,Utilization, and Storage Projects

This study assesses the displacement of coalbed methane by CO₂ migration along a fault into the coal seam in the Yaojie coalfield. Coal and gas samples were collected continuously at various distances in NO.2 coal seam from F19 fault. Vitrinite reflectance, maceral, and pore distributions and proximate analysis of fourteen coal samples were performed. Gas components, concentrations, carbon isotopes of 28 gas samples were determined. We examined the coal–gas trace characteristics of coalbed methane displaced away from the fault by CO₂ injection after geological ages. From east to west, away from the F19 fault, the CO₂ concentration decreased, whereas the CH₄ concentration increased gradually. The δ¹³C values for CO₂ varied between ?9.94‰ and 1.12‰, suggesting a metamorphic origin. A wider range of values (from ?9.94‰ to 20‰) was associated with the mixing of microbial carbon dioxide, isotopic fractionation during CO₂ migration through the microporous structures of coals, and/or carbon isotope fractionation during gas–water exchange and dissolution of CO₂. Away from the F19 fault, the volumes of micropores, mesopores and macropores decrease gradually. The Dubinin–Radushkevich (DR) micropore volume decreased from 0.0059 to 0.0037 cm³ g^‐1, and the mesopore and macropore volumes decreased from 0.066 to 0.026 cm³ g^‐1. The CO₂ injection can mobilize aromatic hydrocarbons and mineral matter from coal matrix, resulting in the decrease in the absorption peak intensity for coal samples after supercritical CO₂ treatment, which indicates that chemical reactions occur between coal and CO₂, not only physical adsorption.

从《张家山汉简》谈汉初的户赋与户刍

本文从《张家山汉简》所出汉初法律条文着手,对汉初户赋和户刍的性质进行了细致分析,指出二者是一种特殊性质的户税,具有税率很轻的特点。由此,进一步探讨了汉代户税的演变过程,认为文景与武帝时期社会状况的变化是导致汉代户税不断加重又突然消失的重要原因。     

Reporting by Letter: The 2nd Earl of Hardwicke and his Parliamentary Correspondents

For much of the 18th century, letter writing remained an important means of communicating news about proceedings at Westminster. Members of leading parliamentary families such as the Hardwickes were prolific letter writers and their correspondence has long been valued as a source for the period before the regular reporting of debates became established in the newspaper press. This article focuses on reporting by letter in the correspondence of the 2nd earl of Hardwicke and his circle. It reconstructs Hardwicke's network of informants and considers how the nature of their connection with the earl affected the way they conceived of their role as reporters. With reference to the epistolary conventions of the time, it asks how the circumstances in which letters were composed and read may have shaped the style and content of the reports. Finally, the article examines the impact made on the epistolary tradition by the emergence of newspaper reporting in the later 18th century and assesses the extent to which this development led letter writers to adjust their methods and goals.     

Gas breakthrough pressure for hydrocarbon reservoir seal rocks: implications for the security of long-term CO2 storage in the Weyburn field

This paper reports a laboratory study of the gas breakthrough pressure for different gas/liquid systems in the Mississippian‐age Midale Evaporite. This low‐permeability rock formation is the seal rock for the Weyburn Field in southeastern Saskatchewan, Canada, where CO₂ is being injected into an oil reservoir for enhanced recovery and CO₂ storage. A technique for experimentally determining CO₂ breakthrough pressure at reservoir conditions is presented. Breakthrough pressures for N₂, CO₂ and CH₄ were measured with the selected seal‐rock samples. The maximum breakthrough pressure is over 30 MPa for N₂ and approximately 21 MPa for CO₂. The experimental results demonstrate that the Weyburn Midale Evaporite seal rock is of high sealing quality. Therefore, the Weyburn reservoir and Midale Beds can be used as a CO₂ storage site after abandonment. The measured results also show that the breakthrough pressure of a seal rock for a gas is nearly proportional to the interfacial tension of the gas/brine system. The breakthrough pressure of a CO₂/brine system is significantly reduced compared with that of a CH₄/brine system because of the much lower interfacial tension of the former. This implies that a seal rock that seals the original gas in a gas reservoir or an oil reservoir with a gas cap may not be tight enough to seal the injected CO₂ if the pressure during or after CO₂ injection is the same or higher than the original reservoir pressure. Therefore, reevaluation of the breakthrough pressure of seal rocks for a given reservoir is necessary and of highest priority once it is chosen as a CO₂ storage site.     

移动搜索法在教育公共服务可达性评价中的改进与应用——以福州城区幼儿园为例

采用可变步长的两步移动搜索法,以福建省福州市为典型案例,以居民点（普查小区）为分析单元,对各居民点入园空间可达性进行了测算,并与传统的两步移动搜索法进行对比分析,综合判别学前教育资源空间分布特点。研究表明：福州城区入园可达性总体情况并不理想,仅有少数地区、少量人群可以获得较好的幼儿园空间的可达性。入园可达性在地理空间上呈现出多中心结构,高可达性地区主要分布在市中心并在城市周围零星分布,边缘乡镇特别是除西部以外的乡镇地区缺教明显,入园可达性在城区内部差异较大,幼儿园资源过剩地区和稀缺地区呈两极分化的格局。可变步长的两步移动搜索法能更为客观有效地对幼儿园的布局状况进行评价。而传统方法有一定的夸大作用,且降低了内部的差异,在一定程度上掩饰了幼儿园资源分布的不公平现象。     

Governor Stone: Analysis of an 1877 Two-masted Schooner from the Gulf of Mexico

This article details the historic preservation documentation and construction analysis of the 1877 American 2-masted schooner Governor Stone , a National Historic Landmark. Governor Stone 's construction reflects its intended use as a general freight and oyster schooner, and to a lesser degree its geographic origin along the Gulf of Mexico. While the physical environment of the Gulf Coast necessarily constrained the size of these vessels, 2-masted schooners of the Gulf Coast generally exhibit similarities with their contemporary functional equivalents of other American regions rather than stylistic elements unique to their geography.
