Factorization of weakly compact operators between Banach spaces and Fréchet or (LB)-spaces
No full text[EN] In this note we show that weakly compact operators from a Banach space X into
a complete (LB)-space E need not factorize through a reflexive Banach space. If E is a Fréchet space, then weakly compact operators from a Banach space X into E factorize through a reflexive Banach space. The factorization of operators from a Fréchet or a complete (LB)-space into a Banach space mapping bounded sets into relatively weakly compact sets is also investigated.The research of the first author was partially supported by MEC and FEDER Project MTM2010-15200 and by GV Project Prometeo/2008/101.

Physically inspired interactive music machines: making contemporary composition accessible?
No full textMuch of what we might call "high-art music" occupies the difficult end of listening for contemporary audiences. Concepts such as pitch, meter and even musical instruments often have little to do with such music, where all sound is typically considered as possessing musical potential. As a result, such music can be challenging to educationalists, for students have few familiar pointers in discovering and understanding the gestures, relationships and structures in these works. This paper describes on-going projects at the University of Hertfordshire that adopt an approach of mapping interactions within visual spaces onto musical sound. These provide a causal explanation for the patterns and sequences heard, whilst incorporating web interoperability thus enabling potential for distance learning applications. While so far these have mainly driven pitch-based events using MIDI or audio files, it is hoped to extend the ideas using appropriate technology into fully developed composition tools, aiding the teaching of both appreciation/analysis and composition of contemporary music

Foliar applications of Lo-Biuret Urea and Potassium Phosphite to Navel Orange Trees
No full textThis experiment was established in January 2000 in a block of 'Washington' navel orange trees at Verde Growers, Stanfield, AZ. Treatments included: normal grower practice, winter low biuret (LB) urea application, summer LB urea application, winter LB urea application plus winter and spring potassium phosphite, winter LB urea application plus summer potassium phosphite, and normal grower practice plus spring potassium phosphite. Each treatment was applied to approximately four acres of trees. For 2000-01, yields ranged from 40 to 45 lbs. per tree, and there was no effect of treatments upon total yield. There was a slight effect upon fruit size and grade. Trees subject to summer LB urea application had significantly more fruit of size 56, compared to trees subject to winter LB urea, and untreated, and untreated trees had significantly more fruit of size 88 than did treated trees. Also, treated trees had slightly more fruit in the fancy grade than did untreated trees.Arizona Citrus Research Counci
Wilbur Wright installing launching derricks
No full textPhoto of Wilbur Wright installing the launching derricks at Camp d\u27Auvours. The tower stood at 20 feet and once the 1600 lb. weight was added to the ropes in the middle, the system was designed to help the plane reach flight speed to get off the ground. From the Leon Bollee Album presented to Orville Wright July 17, 1920. This photograph was taken between 08/21/1908 and 01/02/1909.https://corescholar.libraries.wright.edu/special_ms1_photographs/3049/thumbnail.jp

For 2001-02, there was a slight effect of treatment upon yield as LB urea led to improved yield, while potassium phosphite led to reduced yield. Normal grower practice was intermediate between these two extremes. For 2002-03, we noted a large increase in yield, however the yield data was lost when the block was inadvertently harvested.Arizona Citrus Research Counci
Photoelectro-chemical properties of anilino squaraine derivatives in LB films
No full textPhotocurrent generation from Langmuir-Blodgett (LB) overlays on indium tin oxide (ITO) electrodes, where the active components are 2,4-bis[4-(dibutylamino)-2-hydroxyphenyl]squaraine (1) and the unsubstituted analogue, 2,4-bis[4-(dibutylamino)phenyl]squaraine (2), have been investigated. Dye 1 shows improved behaviour compared with the latter and differences in performance are attributed to a modified aggregate structure, this being indicated by variations in the LB film spectra. The photocurrent generation is enhanced by the presence of electron accepters, e.g. N,N'-dimethyl-4,4'-bipyridinium diiodide (MV2+), but quenched by electron donors, e.g. hydroquinone (HQ). The concentration dependence is reported
Resources to help solve drug calculation problems
No full textThis article is the third in a series of articles discussing drug calculations and discusses the resources, in terms of knowledge and skills, that are required to support the use of methods for solving calculation problems (Wright, 2009). The main resources discussed are clinical practice, numeracy knowledge (including number patterns), proportions and factors, and clinical tools such as syringes. These resources can be used as part of formal teaching sessions, or can be developed and practised by individual nurses to improve knowledge and confidence in solving drug calculations. The most important resource for developing drug calculation skills is regular exposure to drug calculations in clinical practice. Any drug calculation teaching and assessing, therefore must have clinical practice as the starting point, with numeracy knowledge not extracted and taught separately, but developed as a resource from within practice, for the purpose of supporting practice.

No full textEffect of Langmuir Blodgett Nanotemplate Crystallisation On Radiation Damage in Lysozyme Studied By Powder Diffraction
No full textPolycrystalline samples of lysozyme were prepared with and without a Langmuir-Blodgett (LB) thin film template. It has previously been shown [1] that the LB nanotemplate influences crystal quality and radiation resistance in single crystals. By using powder diffraction methods we aimed to test this result for a statistical ensemble of millions of crystals at room temperatur
Toward an Interconnectedness 022: Construct LB/1
No full textThe exhibition Toward an Interconnectedness of All Things was created by Barbara Kasten in 1981 and held at the Robert and Elaine Stein Galleries at Wright State University from September 23 through October 24, 1985. Barbara Kasten is an Neo-Constructivist artist. The show was created by a grant through the Ohio Arts Council. A documentary was created in conjunction with the exhibition through the Telecommunications Center. The piece is titled Construct LB/1 , is an 8 x 10 Polaroid.https://corescholar.libraries.wright.edu/restein_interconnect/1000/thumbnail.jp
