It Is Absolutely Necessary That They Be Dislodged

The partial penetration of Railroad Redoubt by Sgt. Joseph E. Griffith and twelve men of the 22nd Iowa had never really threatened to capture that work for the Federals. Nor could the Confederates easily evict those Unionists. The work constituted part of no-man’s-land for most of May 22 until orders arrived from Pemberton to reclaim the entire redoubt. Brigade leader Stephen D. Lee assigned the task to Col. Thomas N. Waul, who organized a small band of volunteers from his Texas Legion. Helped by Col. Edmund W. Pettus of the 20th Alabama, who volunteered to lend his services to the group, they counterattacked along the parapet that extended toward the southeast corner of the work where Griffith’s party had been ensconced. By this time, late in the afternoon, Griffith and his men had quietly evacuated the work but there were still Federal troops taking shelter in the ditch in front of it. Pettus’ counterattack not only reclaimed all of Railroad Redoubt but soon drove the Federals out of the ditch as well. Far from a campaign-winning opportunity, as McClernand portrayed Griffith’s penetration to Grant earlier that day, the struggle for Railroad Redoubt ended with a relatively easy Confederate defensive success.

Thin film samples of pristine polyvinyl chloride (PVC), poly vinyldine fluoride (PVDF) in combination with their blend in addition to samples containing factorial mass fraction of multi wall carbon nano-tubes (MWCNTs) in the dopant level were prepared via routine casting technique using tetrahydrofurane (THF) as a common solvent. X-ray diffraction and transmission electron microscopy (TEM) depict the nano-scale (15-25 nm) of functionalized MWCNTs with no surface damage results from functionalization process.X-ray diffraction (XRD) shows a semi-crystalline nature of PVDF with evidence for more than one phase namely a and b phases. The fraction of b phase was calculated and correlated to the dopant content. FTIR optical absorption spectra revels a preservation of the main vibrational bands before and after addition of MWCNTs in the doping level with a presence of new small band 1151 cm-1 assigned for the interaction and complexation between constituents.

Like every animal, human offspring evolved to fit into their communities, but social fittedness for mammals requires a supportive early nest that fosters socio-emotional intelligence, self-regulation, and sympathy. Within a supportive environment, children naturally develop orientations that facilitate prosocial behaviours within the community. We use the evolved developmental niche (EDN), apparent in 95% of human history as small-band hunter-gatherers, for a baseline representative of human evolution. In these societies, children grow into cooperative, agile moral actors. We compare the EDN with five modern approaches to young child group care and make suggestions to early caregivers on how to provide, in the modern world, what children evolved to need.

To show that an adsorbing biofilm carrier (GAC) can be advantageous for atrazine bioremediation over a non-adsorbing carrier, fluidized bed (FB) reactors were operated under atrazine limiting concentrations using Pseudomonas sp. strain ADP as the atrazine degrading bacteria. The following interrelated subjects were investigated: 1) atrazine adsorption to GAC under conditions of atrazine partial penetration in the biofilm, 2) differences in atrazine degradation rates and 3) stability of atrazine biodegradation under non-sterile anoxic conditions in the GAC reactor versus a reactor with a non-adsorbing biofilm carrier. Results from batch adsorption tests together with modeling best described the biofilm as patchy in nature with covered and non-biofilm covered areas. Under conditions of atrazine partial penetration in the biofilm, atrazine adsorption occurs in the non-covered areas and is consequently desorbed at the base of the biofilm substantially increasing the active biofilm surface area. The double flux of atrazine to the biofilm in the GAC reactor results in lower effluent atrazine concentrations as compared to a FB reactor with a non-adsorbing carrier. Moreover, under non-sterile denitrification conditions, atrazine degradation stability was found to be much higher (several months) using GAC as a biofilm carrier while non-adsorbing carrier reactors showed sharp deterioration within 30 days due to contamination of non-atrazine degrading bacteria.
