TEM Measurements on Bi1 xSbx Nanowires
room temperature thermoelectric applications, while bismuth antimony alloys exhibit high efficiencies at liquid nitrogen temperature [3]. The synthesis of bismuth compound nanowires with controlled size and crystallinity, and the systematic study of their thermoelectric properties will thus contribute to better understand the influence of mesoscopic and quantum size effects on the thermoelectric characteristics of nanostructured materials. We have successfully synthesized 20-nm diameter Bi1−xSbx nanowires with different composition by potentiostatic electrochemical deposition in ion track-etched membranes [4] applying the same voltage for all samples. Electrolytes with different relative concentration of Bi and Sb ions (c(Bi) and c(Sb), respectively) were employed. The concentration of Sb in the nanowires (x) was measured with a TEM-EDX system. The EDX spectra showed signals also from Pb and Al probably due to stray radiation and impurities introduced during the preparation for TEM. The values for 1 − x and x are presented in Tab. 1, each representing the average of several measuring spots on nanowires fabricated with the same electrolyte. As a result, the concentration of Sb in the Bi1−xSbx nanowires can be controlled by the concentration of Sb ions in solution, in the case of potentiostatic deposition. HRTEM images revealed that all nanowires were polycrystalline, the average grain size increasing with increasing Sb concentration. This is in agreement with the fact that during deposition of nanowires with higher Sb concentrations, the current density was lower, i. e. the growth rate was slower.
APL\?
This paper describes a version of APL based upon the dictionary [1], but significantly simplified and enhanced, and directly usable on any machine that provides ASCII characters. It also describes salient features of a C implementation that has been tested on several machines, and is available as freeware. There have been four primary motivations for this work:To provide an APL system for use in teaching mathematics and related topics that is modern, free, and transportable.
To devise a spelling scheme based on the ASCII alphabet that preserves the major advantages of the one-letter words based on the special alphabet commonly used in APL.
To exploit the advantages of breaking from the strict conformance with earlier APL that is normally obligatory in commercial systems.
To explore an unusual style of C programming that makes heavy use of pre-processing facilities.

Examples of the use of the language in a variety of topics are provided in an appendix.

A cytochemical and ultrastructural study of acute myelomonocytic leukemia exhibiting the pseudo-Chediak-Higashi anomaly of leukemia and "splinter-type" Auer rods.
An unusual case of acute myelomonocytic leukemia (AMML) in an 81-year-old man is described. Ultrastructural examination revealed the presence of distinct Auer bodies, which commonly are found in acute promyelocytic leukemia (APL). The Auer bodies had a splinterlike appearance with a distinct tubular substructure. The morphologic appearance of the leukemic cells coupled with the results of cytochemical staining reactions (alpha-naphthyl AS-D chloroacetate esterase, alpha-naphthyl butyrate esterase, Sudan black B, and periodic acid-Schiff reaction) identified this leukemia as myelomonocytic in origin. APL-like Auer rods in AMML now can be included in the spectrum of morphologic forms commonly seen in myelogenous leukemia and lends support to the hypothesis of an aberrant stem cell. In addition to the APL-like Auer rods, the leukemic blasts contained giant pink-staining granules on Wright's stain, some of which had a tubular substructure similar to the Auer rods under the electron microscope. The presence of these megagranules is a morphologic aberration termed "the pseudo-Chediak-Higashi anomaly of acute leukemia," and now has been described for the first time in AMML at the ultrastructural level.
