Abstract Nutrient stratification of no‐till managed soil can affect test analysis levels plant‐available phosphorus (P). Research has suggested sampling to different depths due acidity, but little work been conducted investigate any change recommendations for immobile nutrients. The objective this study was determine the depth that had greatest relationship with yield response fertilizer‐P. sam...

SBA-15 is an interesting mesoporous silica material having highly ordered nanopores and a large surface area, which is widely employed as catalyst supports, absorbents, drug delivery materials, etc. Since it has a lack of functionality, heteroatoms and organic functional groups have been incorporated by direct or post-synthesis methods in order to modify their functionality. The aim of this art...

Current models of T cell memory implicate a critical role for IL-7 in the effector-to-memory transition, raising the possibility that IL-7 therapy might enhance vaccine responses. IL-7 has not been studied, to our knowledge, before now for adjuvant activity. We administered recombinant human IL-7 (rhIL-7) to mice during immunization against the male antigen HY and compared these results with th...

That the signal transduction pathways used by the cytokines IL-2 and IL-15 are identical would suggest that these cytokines have redundant roles in lymphoid development; instead, IL-2 is the guardian of thymus-derived T-cell homeostasis, while interleukin-15 promotes extrathymic development of T and NK cells.

Tungsten oxide nanoclusters supported highly ordered mesoporous SBA-15 material has been successfully synthesized in a single step using a non-ionic surfactant as a template and used for the selective oxidation of sulfur compounds, giving excellent yields at room temperature with exceptional catalyst recyclability.

BACKGROUND In groups of patients with formaldehyde allergy, many have positive patch tests to quaternium-15. Conversely, of patients allergic to quaternium-15, over half also react to formaldehyde. OBJECTIVES To test our hypothesis that patients with stronger patch test reactions to formaldehyde are more likely to react to quaternium-15, attesting to the aetiological role for formaldehyde in ...

Speech can lead to increased performance in computer-based problem solving. Studies of complex interaction styles — such as command-line or system-delayed interaction — have found that complex interaction styles can lead to savings in the number of actions users take to reach a solution for certain tasks compared with direct manipulation. Speech can be viewed a complex interaction style because...

The structural stability of sulfolane (tetrahydrothiophene1,1-dioxide) and 3-sulfolene (dihydrothiophene1,1-dioxide) was investigated by DFT-B3LYP and ab initio MP2 calculations with 6-311+G**) basis set. The calculated symmetric ring-puckering potential of 3-sulfolene at the B3LYP level is consistent with a flat minimum that corresponds to a planar ring but at the MP2 level with a double minim...
