Data shows that many of the census tracts with higher rates of diabetes in Long Beach are also low-income areas, where a significant number of residents are located over…

This is concordant with several archaeological indicators showing long-term increases in population density in the Upper Paleolithic and Late Stone Age, including increased small-game exploitation, greater pressure on easily collected prey species like tortoises and shellfish, and more intense hunting of dangerous prey species. We further note that much of the literature pointing to sudden…

We sought to create as diverse of a starting inoculum as possible, and thus we sampled from multiple fields that had different tomato genotypes and different surrounding plants, as microbes from surrounding plants are known to contribute to colonization of the phyllosphere. Tomato genotypes sampled for inoculum preparation included Beef-eaters, Romas, Lucky Tiger, Red Cherry,…

From the original inoculum sample, we identified ten Operational Taxonomic Units using linear discriminant analysis effect-size analysis that were significantly associated with particular genotypes in P1 and P2. We compared their presence/absence at the end of P4 to those OTUs that were not found to be associated with genotype. Interestingly, those OTUs that were significantly associated with…

The labor category does not appear clearly on the chart because of the low need for labor hours since the indoor facility is highly automated.In both DSP scenarios, facility-dependent costs have the highest cost impact. Insurance, local taxes, and other overhead expenses are estimated to be 1%, 2%, and 5% of the section’s DFC, respectively. Maintenance…

Because of the calendar’s importance for societal organization, the early chroniclers of Aztec, or Mexica, civilization, in particular, Bernardino de Sahagún and Diego Durán , left behind detailed descriptions of their calendar system. They both underscored the precision of the method used to keep track of seasons and the fact that the Mexica were well aware…

Diet composition was slightly more diverse in the fallow treatment with an average of 87.3% ± 2.6% SE percent of prey items composed of cladocerans compared with an average of 97.4% ± 1.2% SE in the disced treatment and 97.3% ± 1.0% SE in the stubble treatments. A chironomid midge hatch in the southernmost field was…

Push-pull factors refer to the influence of off-farm employment wages that may influence an individual’s decision to be an entrepreneur or push them to seek off farm employment. For this analysis, this influence could be considered on an individual basis or at a spousal level. The change incentives when both spouses’ incomes come from farming could…
