The access to water and the engineered landscapes accommodating its collection and allocation are pivotal issues for assessing sustainability. Recent mapping, sediment coring, and formal excavation at Tikal, Guatemala, have markedly expanded our understanding of ancient Maya water and land use. Among the landscape and engineering feats identified are the largest ancient dam identified in the Ma...

Age-of-dam adjustment factors are used to preadjust birth and weaning weight data for national beef cattle genetic evaluations. Adjustments are used in order to make the means of the different age-of-dam subclasses similar so that a fair comparison of animals can be performed. A review was made of various research studies that have estimated age-of-dam adjustment factors for birth weight and we...

Two major branches of engineering mechanics are fluid mechanics and structural mechanics, with many practical problems involving the effect of the first on the second. An example is the design of an aircraft's wings to bend within reasonable limits without breaking under the action of lift forces exerted by the air flowing over them; another is the maintenance of the structural integrity of a d...

As a departure from traditional situational perspectives, researchers have given increased attention to the dispositional basis of attitudes. Recently, Hepler and Albarracín (2013) introduced a construct that they called "dispositional attitude" and provided validity evidence for a new scale--the Dispositional Attitude Measure (DAM). Although the DAM was introduced as a "new" approach for asses...

Salmonella isolates that lack or overproduce DNA adenine methylase (Dam) elicited a cross-protective immune response to different Salmonella serovars. The protection afforded by the Salmonella enterica serovar Typhimurium Dam vaccine was greater than that elicited in mice that survived a virulent infection. S. enterica serovar Typhimurium Dam mutant strains exhibited enhanced sensitivity to med...

Eight preparations of soluble amyloid and degraded amyloid (DAM) were compared immunologically. Unlike amyloid fibrils, six of eight preparations of DAM proved to be relatively strong immunogens. Antisera to DAM reacted weakly or not at all with normal human serum or extracts of normal tissues, but were specifically reactive with amyloid fibrils or DAM. Comparative studies of DAM'S from eight d...

water. The River Omo, site of the Gibe dam, flows south into Kenya and Lake Turkana. Some estimates suggest the country has the potential to generate 45,000 MW of hydroelectric power. While work continues on Gibe III, Ethiopia has already approved plans for several new schemes, including a giant 2,100 MW project on the Blue Nile and a number of other dams have already been built or are close to...
