A Messenger for Change

It is now time for all educators to embrace the power of a social epidemic. Schools across Texas are embracing a “New Vision for Texas Public Schools”. This vision embraces schools where all students are engaged in relevant, rigorous, meaningful activities and where classrooms reflect innovation, creativity, problem-solving, collaboration, communication and critical thinking. In this new vision, daily standardized test preparation and boring fact-memorization skills are replaced with digital learning, curriculum standards relevant to real-world challenges, multiple assessments for student performance, and accountability that’s based on a combination of measures, not just one state mandated test. It is about creating student-centered schools and future-ready students

What Is a Good Swine Ration?

Feed costs make up 65-75 percent of the cost of producing pork, and the ration you feed plays a major role. But keep in mind that it\u27s your over-all management that can make the difference between success and failure

A Situation Report - Slotted Floors for Hogs?

Are self-cleaning slotted floors the answer to the waste-disposal and cleaning problems when you raise hogs in confinement? It\u27s too early for a final answer, but here\u27s a summary of results and developments so far

Trimethylphosphate as a Methylating Agent for Cross Coupling: A Slow-Release Mechanism for the Methylation of Arylboronic Esters.

A methyl group on an arene, despite its small size, can have a profound influence on biologically active molecules. Typical methods to form a methylarene involve strong nucleophiles or strong and often toxic electrophiles. We report a strategy for a new, highly efficient, copper and iodide co-catalyzed methylation of aryl- and heteroarylboronic esters with the mild, nontoxic reagent trimethylphosphate, which has not been used previously in coupling reactions. We show that it reacts in all cases tested in yields that are higher than those of analogous copper-catalyzed reactions of MeOTs or MeI. The combination of C-H borylation and this methylation with trimethylphosphate provides a new approach to the functionalization of inert C-H bonds and is illustrated by late-stage methylation of four medicinally active compounds. In addition, reaction on a 200 mmol scale demonstrates reliability of this method. Mechanistic studies show that the reaction occurs by a slow release of methyl iodide by reaction of PO(OMe)3 with iodide catalyst, rather than the typical direct oxidative addition to a metal center. The low concentration of the reactive electrophile enables selective reaction with an arylcopper intermediate, rather than nucleophilic groups on the arylboronate, and binding of tert-butoxide to the boronate inhibits reaction of the electrophile with the tert-butoxide activator to form methyl ether

An unusual SAR arc observed during ring current development, 4 August 1972

Measurements made from the ISIS-II spacecraft at 1400 km and ground-based measurements from New Zealand provide a detailed description of an unusual SAR arc observed at dusk on 4 August 1972, during the growth phase of the ring current. Proton precipitation was observed over a latitude range of a few degrees, with electron temperature enhancements throughout the region but espeically at its boundaries, and an F-region trough was present at the equatorward boundary. SAR arcs usually occur at equatorward proton boundaries but this one appeared at the poleward boundary, which seems to have given rise to a number of unusual features. Characteristics unique to this event are a high flux of low energy electrons at the SAR arc location, associated with an upward field-aligned current there, and a "slot" in the ambient electron density, which falls to 5% of the background density over a region of 1.5 km half-width. Immediately poleward of the low energy electron flux, intense whistler mode noise (0.1-0.4 MHz) is evident. The 6300 A emission, which has a total intensity of 10.6 kR, appears divided into two components, one at 285 km excited by the low energy electrons, and the other at 400 km, excited thermally by the electron gas. Comparisons are made with S3-A spacecraft observations made in the equatorial region at the same time, with ISIS-II observations of a more normal SAR arc, and with other observations reported in the literature. The kinetic Alfven wave process described by Hasegawa and Mima (1978) seems a candidate for the acceleration of these low energy electrons, but it is not possible to entirely exclude the alternative of an auroral-type acceleration process.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/23358/1/0000302.pd

High iso aldehyde selectivity in the hydroformylation of short-chain alkenes

The authors thank the Eastman Chemical Company for funding (LI, and later JAF) and permission to publish. The EPSRC (EP/M003868/1) is also acknowledged for funding (JAF).The hydroformylation of propene to give predominantly iso‐butanal has been achieved; class‐leading selectivity is possible even at higher temperatures that deliver fast conversion. Racemic rhodium complexes of bidentate phospholane phosphites derived from tropos‐biphenols and unusual solvent systems are the key to the selectivity observed.PostprintPeer reviewe

I. An ion-exchange method for a volumetric determination of sulfate. II. A study of iron(III) sulphate complex ions. III. A sodium coulometer. IV. A sodium ion glass electrode

NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. A procedure has been developed for a volumetric determination of sulfate in solutions containing iron(III), chloride, and bromide. A solution is passed through the hydrogen form of a cation exchange resin, the effluent is titrated for hydrogen and for halide ion, and the sulfate is calculated from these titrations. The procedure was successfully used for a determination of sulfur in a pyrite ore. The complexing of iron(III) with sulfate was studied both spectrophotometrically and by an equilibrium ion-exchange distribution method. Association constants and extinction coefficients for the [...] and [...] complex ions were obtained from these studies. Resistance measurements and a study of the effect of current flow were made on a redesigned sodium coulometer. A number of the liabilities inherent in a sodium coulometer were considered. A literature survey was made on the behavior of clay, ion-exchange, and glass membranes in solutions of various ionic species. Glass-membrane electrodes were prepared from four types of glass. The sodium-ion response of these electrodes in various buffer solutions was determined by following the change in potential of a glass-membrane electrode--buffer solution--calomel electrode system caused by varying the sodium-ion concentration of the solution. Resistance measurements were made on some of the glass membranes
