This chapter presents material to help students explore playing melody in chordal textures, above an Alberti bass, in an arpeggiated texture, and in single-line playing laced with occasional chords. The uninitiated often view the guitar as a chordal instrument, but technical and interpretive mastery requires the ability to voice any note in any texture at will. Refined and artistic voicing is often difficult for guitarists because the articulation of different parts of a musical texture are divided among the fingers of one hand instead of between two hands, as is often the case on the piano. Karl Leimer acknowledged this difficulty for pianists in 1932, and it holds true for guitarists. The problem is one of right-hand finger independence. Of special interest is the presentation of historical right-hand fingering practices for Alberti bass textures, which are different from those found in modern method books or assumed by modern players.

Repeated notes are used frequently in compositions for the guitar as a way to provide the illusion of greater sustain or as a technique to add brilliance. Modern guitarists usually think of tremolo technique when they think of repeated notes, but tremolo technique is relatively recent. This chapter documents the practices used by early lutenists and 19th-century guitarists to play repeated notes and it provides material for studying the various ways these musicians developed their techniques. The discussion of Fernando Sor’s use of the right-hand thumb and index finger for repeated notes will be of interest to today’s guitarists. This chapter also explores the ways in which 19th-century guitarists played passages that modern guitarists might assume to be examples of modern tremolo technique. The fingering practices in this chapter are not covered in standard modern method books.

(1) These experiments prove that the fumigator is safer to use than the dumping fixture, because high concentrations of the poison gas are avoided, so that dangerous pockets are not developed.(2) The poison gas is more evenly distributed over the different parts of the section of the ship under treatment.(3) High concentrations, however, can be developed^ at will in any part which requires special attention.(4) The maximum concentrations of the poison gas were obtained in every part of the section in a shorter time, when the fumigator was used, than when the dumping fixture was employed.(5) The artificial ventilation caused by the fan, which is capable of blowing into the section 500 to 1000 cubic feet of fresh air per minute, according to the speed of the motor, materially assists the rapid clearing of the poison gas from the ship, after it has accomplished its work. It is thus possible to complete the fumigation and ventilation of a ship in 3 hours using the cyanide fumigator, while more than 4 hours are required for the dumping fixture.(6) Even more important is the fact that smaller quantities of cyanide can be used with greater efficiency in the fumigator, than larger quantities, with less efficiency in the dumping fixture.(7) The general conclusion is arrived at, that, from the point of view of efficiency, safety and economy, the fumigator is superior to the dumping fixture. Creel has shown that, in respect to the time required for completing the fumigation, and in respect to the thoroughness of the process, both in killing rats and insects, the dumping fixture is superior to the Clayton gas machine. It follows, therefore, that the cyanide fumigator is very much superior in these respects to the Clayton gas machine.

Most of the music in The Classical Guitar Companion makes use of the same technique or musical texture throughout. High-level virtuoso playing requires that guitarists become adept at navigating ever-changing musical textures and the techniques required to produce them. Florid or virtuoso études present the challenges of combining and switching between various technical elements, such as arpeggios, scales, slurs, and shifts, at rapid tempi. Of special interest is the brief discussion of “latency” at high speeds, which is applicable to these studies, and how virtuoso players transcend the limits of the central nervous system when initiating a movement or series of movements that must occur in less time than it takes for the signal to move to get from the brain to the hands (100 milliseconds).

This performative piece, an enactment of lived feminism, acknowledges the privileges and explores the similarities and differences between three cis-gendered white women in different parts of the United Kingdom and how these aid and hinder collaboratively writing together. The piece was shared at the Autoethnography Special Interest Group at International Congress of Qualitative Inquiry (ICQI) in 2018. We had never written together before but had presented on the same Shame? panel at ICQI in 2017 convened by Alys Mendus that also included papers by Stacy Holman Jones and Anne Harris and a memorial to Sue Porter. There were similarities in terms of themes explored including sexuality and taboo. This was our starting point but it was not easy. We realized that difficulty within collaborative inquiry is rarely written about and published but is often the topic of conversation between academics. Perhaps feminism is our ability to stand together curious and alive to our nonshared experience with a commitment to not creating a shared perspective? To stay standing together, we could be stronger in these troubling times.

Probably no individual subject in the whole field of the topography of ancient Italy has attracted the attention of scholars to a greater degree than the quest for Horace's Sabine farm. The appeal which any contribution to the discussion of this question is sure to make to the historical and the literary student alike, and the special interest which the recent excavations at the probable site of the villa have aroused, encourage me to publish a monument, hitherto, I believe, unnoticed, which appears to deserve serious consideration in this connexion. This monument (fig. 14) is a bas-relief of a good quality of limestone, height 1 ft. 10¾ ins. (0·58 m.), width I ft. (0·30 m.), built into the wall of the palace of the Marchese di Roccagiovine at the town of that name, not far from the well-known inscription (fig. 15) commemorating the restoration by Vespasian of a temple of Victoria. The relief represents a female figure, clad in chiton and himation, facing to front; the head is much worn; the right hand clasps the forelegs of a deer; the left hand is badly damaged, so that its action is no longer intelligible.

Mitochondrial alterations were studied in 25 liver biopsies from patients with alcoholic liver disease. Of special interest were the morphologic resemblance of certain fine structural variations in mitochondria and crystalloid inclusions. Four types of alterations within mitochondria were found that seemed to relate to cytoplasmic crystalloids.Type 1 alteration consisted of localized groups of cristae, usually oriented in the long direction of the organelle (Fig. 1A). In this plane they appeared serrated at the periphery with blind endings in the matrix. Other sections revealed a system of equally-spaced diagonal lines lengthwise in the mitochondrion with cristae protruding from both ends (Fig. 1B). Profiles of this inclusion were not unlike tangential cuts of a crystalloid structure frequently seen in enlarged mitochondria described below.

In the design engineering of high performance electromagnetic lenses, the direct conversion of electron optical design data into drawings for reliable hardware is oftentimes difficult, especially in terms of how to mount parts to each other, how to tolerance dimensions, and how to specify finishes. An answer to this is in the use of magnetostatic analytics, corresponding to boundary conditions for the optical design. With such models, the magnetostatic force on a test pole along the axis may be examined, and in this way one may obtain priority listings for holding dimensions, relieving stresses, etc..The development of magnetostatic models most easily proceeds from the derivation of scalar potentials of separate geometric elements. These potentials can then be conbined at will because of the superposition characteristic of conservative force fields.

We have designed and built an electronic device which compares the resistance of a defined area of vacuum evaporated material with a variable resistor. When the two resistances are matched, the device automatically disconnects the primary side of the substrate transformer and stops further evaporation.This approach to controlled evaporation in conjunction with the modified guns and evaporation source permits reliably reproducible multiple Pt shadow films from a single Pt wrapped carbon point source. The reproducibility from consecutive C point sources is also reliable. Furthermore, the device we have developed permits us to select a predetermined resistance so that low contrast high-resolution shadows, heavy high contrast shadows, or any grade in between can be selected at will. The reproducibility and quality of results are demonstrated in Figures 1-4 which represent evaporations at various settings of the variable resistor.

Illuminating Beam

The principles of tandem scanning reflected light microscopy and the design of recent instruments are fully described elsewhere and here only briefly. The illuminating light is intercepted by a rotating aperture disc which lies in the intermediate focal plane of a standard LM objective. This device provides an array of separate scanning beams which light up corresponding patches in the plane of focus more intensely than out of focus layers. Reflected light from these patches is imaged on to a matching array of apertures on the opposite side of the same aperture disc and which are scanning in the focal plane of the eyepiece. An arrangement of mirrors converts the central symmetry of the disc into congruency, so that the array of apertures which chop the illuminating beam is identical with the array on the observation side. Thus both illumination and “detection” are scanned in tandem, giving rise to the name Tandem Scanning Microscope (TSM). The apertures are arranged on Archimedean spirals: each opposed pair scans a single line in the image.
