Dramatic Fall

Recent investigations at the Bostrom site in southwestern Illinois demonstrate that the site was occupied by at least three successive groups of Paleo-Indians: Clovis, Gainey, and Holcombe. Of the artifacts for which lithic raw materials were identified, Clovis tools are manufactured from stone that was procured up to 1500 km from the site. Gainey and Holcombe artifacts, on the other hand, are manufactured from stone whose source areas occur within a radius of 300 km from the site. Early Archaic, Dalton artifacts are manufactured from stone procured within 150 km of the site. These lithic resource procurement patterns suggest that there is a dramatic fall-off in mobility, social interaction, or both, after the initial peopling of the area. The presence of Great Lakes and Northeastern tool types at this southerly latitude suggests that the Gainey and Holcombe economies were much broader than the stereotypical model of a caribou-based subsistence strategy.

Ethnographic examples of stone-tool makers in Australia and archaeological examples from three different areas in the western United States indicate that the availability of lithic raw materials is an important variable conditioning stone-tool production technology. Attributes of availability such as abundance and quality of lithic raw materials condition the production of formal- vs. informal-tool types. Poor-quality raw materials tend to be manufactured into informal-tool designs. High-quality lithic raw materials tend to be manufactured into formal-tool designs when such materials occur in low abundance. When high-quality materials occur in great abundance both formal- and informal-tool designs are manufactured. Other factors, such as residential mobility or sedentism, are found to be less-important determinates of lithic-production technology.

In 1981 and 1982 a 160 m2 block was opened into the Early Archaic deposits at the Rucker's Bottom site in northeast Georgia along the upper Savannah River. An assemblage dominated by Palmer points, expedient flake tools, and debitage was recovered, and is compared to Early Archaic assemblages from elsewhere on the southeastern Atlantic slope. While there is considerable variability in the quantity of material recovered from individual sites over the region (something interpreted here as due in large measure to reoccupation), the composition, or content of Early Archaic assemblages is surprisingly uniform. Most assemblages are characterized by crude bifacial core/tools, expedient unifaces, and debitage. Other tool types, particularly hafted bifaces, formal unifaces, and cobble tools, are less common. Extralocal raw materials most commonly appear on sites along major river drainages, while raw material use in the interriverine area appears directed to local sources. A high degree of group mobility, particularly along major drainages, is suggested.

Lithic Raw Materials

The Rompecráneo is a special kind of lithic artifact which was, presumably, involved in the capture of pinnipeds carried out along the Patagonian coast of Argentina during prehistoric times. Recent papers had offered some information about their morphology but up to now they are poorly studied. In order to offset this situation in a previous work we addressed their role in hunting technics developed at the archaeological locality of Punta Entrada (Santa Cruz, Argentina). This allowed us to propose that rompecráneos were used in combination with spears when hunting on the coast. With the aim of expanding this information, here we present an image gallery of some rompecráneos recovered there. Two of these pieces share a similar morphology but were made of different lithic raw materials. The other one has the appearance of a bola stone but its weight is higher than other bola stones in Patagonia. That is why it is considered a different kind of artifact. The importance of studying these kinds of artifacts is that they have the potential of providing information about the way people interacted with the different resources (biotic and abiotic) in the past so that a better understanding of human behavior can be developed.   Gallery Figure 1.

Critical Raw Materials

This editorial reports on a thorough analysis of the abundance and scarcity distribution of chemical elements and the minerals they form in the Earth, Sun, and Universe in connection with their number of neutrons and binding energy per nucleon. On one hand, understanding the elements’ formation and their specific properties related to their electronic and nucleonic structure may lead to understanding whether future solutions to replace certain elements or materials for specific technical applications are realistic. On the other hand, finding solutions to the critical availability of some of these elements is an urgent need. Even the analysis of the availability of scarce minerals from European Union sources leads to the suggestion that a wide-ranging approach is essential. These two fundamental assumptions represent also the logical approach that led the European Commission to ask for a multi-disciplinary effort from the scientific community to tackle the challenge of Critical Raw Materials. This editorial is also the story of one of the first fulcrum around which a wide network of material scientists gathered thanks to the support of the funding organization for research and innovation networks, COST (European Cooperation in Science and Technology).

Ferronickel Slag

In recent years, efforts to reduce greenhouse gas emissions have continued worldwide. In the construction industry, a large amount of CO2 is generated during the production of Portland cement, and various studies are being conducted to reduce the amount of cement and enable the use of cement substitutes. Ferronickel slag is a by-product generated by melting materials such as nickel ore and bituminous coal, which are used as raw materials to produce ferronickel at high temperatures. In this study, we investigated the fluidity, microhydration heat, compressive strength, drying shrinkage, and carbonation characteristics of a ternary cement mortar including ferronickel-slag powder and fly ash. According to the test results, the microhydration heat of the FA20FN00 sample was slightly higher than that of the FA00FN20 sample. The 28-day compressive strength of the FA20FN00 mix was approximately 39.6 MPa, which was higher than that of the other samples, whereas the compressive strength of the FA05FN15 mix including 15% of ferronickel-slag powder was approximately 11.6% lower than that of the FA20FN00 mix. The drying shrinkage of the FA20FN00 sample without ferronickel-slag powder was the highest after 56 days, whereas the FA00FN20 sample without fly ash showed the lowest shrinkage compared to the other mixes.

Abstract Objective: This study aims to evaluate the long-term impact of living in post-disaster prefabricated temporary housing on social interaction activities and mental health status. Methods: A total of 917 adult residents in a coastal town, whose residences were destroyed by the tsunami caused by the Great East Japan Earthquake (GEJE), were enrolled for the assessment held five years after the disaster. They answered questions about their experience and consequence of living in prefabricated temporary housing after the disaster. Their present scores on five types of self-reported measures regarding the psychosocial or psychiatric status and their present and recalled social interaction activities were cross-sectionally collected. Results: A total of 587 (64.0%) participants had a history of living in prefabricated temporary housing, while the other 330 (36.0%) had not. The prevalence of social interaction activities significantly decreased after the GEJE. However, the experience of living in prefabricated temporary housing did not adversely affect the subsequent social interaction activities or mental conditions of the participants five years after the disaster. Conclusions: Living in post-disaster prefabricated temporary housing may not negatively impact subsequent psychosocial conditions or social interaction activities five years later.

Studies were made in 5 monkeys, 7 rabbits, and 33 cats of the effect of gram-negative endotoxin on aortic, pulmonary artery (PAP), and portal venous (PVP) pressures; and on changes in weight of a short segment of intestine. Studies of blood pooling were also made in 12 cats. The responses in these species were compared with those previously observed in the dog. Although variable degrees of hypotension developed at one time or another in all animals following injection of endotoxin, the early precipitous hypotension that characteristically occurs in the dog was observed only in the cat. However, in this species the dramatic fall in pressure could be ascribed to pulmonary vascular constriction and acute right ventricular hypertension and failure, and not to splanchnic pooling. PAP also became elevated in the monkey and the rabbit, but usually was of lesser magnitude and did not appear to explain the development of the relatively late hypotension that occurred in these species. The absence of significant increases in gut weight and the minor increments in PVP in all animals indicate that in none of these species is hepatic vein constriction and splanchnic pooling a significant mechanism in producing early shock as it is in the dog. Pathologic gross and microscopic studies in the monkey and gross examinations in the other species supported this conclusion.

AbstractAn attempt has been made to assess new potential applications for the Bailén clays, traditionally used for manufacturing bricks, based on mineralogical, chemical, particle size, plasticity and firing results. Raw materials and mixtures used by the local factory were selected and tested with the addition of some diatomite, feldspar or kaolin. Based on their properties, clay materials from Bailén might be suitable for making porous red wall tiles, clinker, vitrified red floor tiles and porous light-coloured wall tiles by pressing; the first could be manufactured from the raw materials and mixtures currently used by the local manufactures. On the other hand, stoneware shaped by extrusion, such as perforated bricks, facing bricks and roofing tiles, can be also manufactured from the mixtures used at the factory if they contain 20-25% carbonate and small amounts of iron oxides; lightweight bricks require black and yellow clays with diatomite.

An examination was carried out of the influences of concealing academic achievement on self-esteem in an academically relevant social interaction based on the assumption that concealing socially devalued characteristics should influence individuals' self-esteem during social interactions. An interview paradigm called for school-aged adolescents who either were or were not low (academic) achievers to play the role of students who were or were not low achievers while answering academically relevant questions. The data suggest that the performance self-esteem of low achievers who played the role of good students was more positive than that of low achievers who played the role of low achievers. On the other hand, participants who played the role of good students had more positive performance self-esteem than did participants who played the role of low achievers.
