Initial beam-profiling tests with the NML prototype station at the Fermilab A0 Photoinjector
The beam-profile diagnostics station prototype for the superconducting rf
electron linac being constructed at Fermilab at the New Muon Lab has been
tested. The station uses intercepting radiation converter screens for the
low-power beam mode: either a 100-\mu m thick YAG:Ce single crystal
scintillator or a 1-\mu m thin Al optical transition radiation (OTR) foil. The
screens are oriented with the surface perpendicular to the beam direction. A
downstream mirror with its surface at 45 degrees to the beam direction is used
to direct the radiation into the optical transport. The optical system has
better than 20 (10) \mu m rms spatial resolution when covering a vertical field
of view of 18 (5) mm. The initial tests were performed at the A0 Photoinjector
at a beam energy of ~15 MeV and with micropulse charges from 25 to 500 pC for
beam sizes of 45 to 250 microns. Example results will be presented.Comment: 3 pp. Particle Accelerator, 24th Conference (PAC'11) 2011. 28 Mar - 1

Integrated Application of Active Controls (IAAC) technology to an advanced subsonic transpot project-demonstration act system definition
The 1985 ACT airplane is the Final Active Controls Technology (ACT) Airplane with the addition of three-axis fly by wire. Thus it retains all the efficiency features of the full ACT system plus the weight and cost savings accruing from deletion of the mechanical control system. The control system implements the full IAAC spectrum of active controls except flutter-mode control, judged essentially nonbeneficial, and incorporates new control surfaces called flaperons to make the most of wing-load alleviation. This redundant electronic system is conservatively designed to preserve the extreme reliability required of crucial short-period pitch augmentation, which provides more than half of the fuel savings

Apparent digestibility of nutrients, energy, and amino acid of nontoxic and detoxified physic nut cakes for Nile tilapia.
Abstract: The objective of this work was to evaluate the apparent digestibility coefficients of nutrients, energy, and amino acids of nontoxic and detoxified physic nut cakes treated with solvent plus posterior extrusion, for Nile tilapia. The apparent digestibility coefficients of crude protein and gross energy were higher for detoxified than for nontoxic physic nut cake. However, the apparent digestibility coefficient of ether extract of the nontoxic physic nut cake was higher than that of the detoxified one. The apparent digestibility coefficient of amino acids of both feed ingredients was superior to 80%, except for glycine, for the nontoxic psychic nut cake,and for threonine, for the detoxified one. Nontoxic and detoxified physic nut cakes show apparent digestibilitycoefficient values equivalent to those of the other evaluated oilseeds and potential for inclusion in Nile tilapia diets. Resumo: O objetivo deste trabalho foi avaliar os coeficientes de digestibilidade aparente de nutrientes, energia e aminoácidos de tortas de pinhão-manso atóxica e destoxificada tratadas com solvente e posterior extrusão, para tilápia-do-nilo. Os coeficientes de digestibilidade aparente da proteína bruta e da energia bruta forammaiores para a torta destoxificada do que para a atóxica. No entanto, o coeficiente de digestibilidade aparente do extrato etéreo da torta atóxica foi superior ao da destoxificada. O coeficiente de digestibilidade aparente dosaminoácidos dos dois alimentos foi maior que 80%, exceto para glicina, para a torta atóxica, e para treonina, para a destoxificada. Tanto a torta atóxica quanto a destoxificada de pinhão-manso apresentam valores similares aos das outras oleaginosas avaliadas e potencial para utilização em dietas para tilapia-do-nilo.
