A review of New World Asiracinae (Hemiptera: Auchenorrhyncha: Delphacidae) with five new taxa

Die Gattungen der Asiracinae der Neuen Welt werden im Kontext mit neu entdeckten Taxa aus Ecuador diskutiert und revidiert. Twölf nominelle Gattungen, davon drei Ugyopinae und neun Asiracinae (eine neu) werden aus der Neuen Welt gemeldet. Die tatsächliche Gattungszugehörigkeit der einer bislang zur Gattung Asiraca gestellten Art konnte nicht geklärt werden. Schlüssel zu den Asiracinae der Neuen Welt (ohne Asiraca) und zur Gattung Tetrasteira werden präsentiert. Neu beschrieben werden Pentasteira gen. nov. (Asiracinae: Platysystatini) mit P. albifrons n. sp., sowie drei Arten der Gattung Tetrasteira (Asiracinae: Tetrasteirini): T. vulgaris, n. sp., T. trimaculata n. sp., and T. solata n. sp. Große Mengen von Tetrasteira vulgaris n. sp. wurden im Amazonasbecken von Ecuador in Regenwäldern außerhalb von Überflutungsgebieten durch „canopy fogging“ gesammelt.The genera of New World asiracine planthoppers are reviewed and discussed in the context of new taxa discovered in canopy fogging samples from Ecuador. Twelve nomative genera, including 3 Ugyopinae and 9 Asiracinae (1 new) are reported from the New World, although the generic identity of the single Asiraca species could not be verified. A key to New World asiracinae genera, excluding Asiraca, is provided. The new taxa include Pentasteira gen. nov. (Asiracinae: Platysystatini) with 1 species (P. albifrons n. sp.) and a new Tetrasteira (Asiracinae: Tetrasteirini), prompting a generic revision with three new described species (T. vulgaris, n. sp., T. trimaculata n. sp., and T. solata n. sp.). A key to the species of Tetrasteira is provided. Tetrasteira vulgaris n. sp. has been taken in large numbers in canopy fogging samples from terre firme forest in the Amazon basin in Ecuador

A tabulation of pipe length to diameter ratios as a function of Mach number and pressure ratios for compressible flow

Computer programs and resulting tabulations are presented of pipeline length-to-diameter ratios as a function of Mach number and pressure ratios for compressible flow. The tabulations are applicable to air, nitrogen, oxygen, and hydrogen for compressible isothermal flow with friction and compressible adiabatic flow with friction. Also included are equations for the determination of weight flow. The tabulations presented cover a wider range of Mach numbers for choked, adiabatic flow than available from commonly used engineering literature. Additional information presented, but which is not available from this literature, is unchoked, adiabatic flow over a wide range of Mach numbers, and choked and unchoked, isothermal flow for a wide range of Mach numbers

Tube choledochoureterostomy: A simple method for bile diversion

A technique of bile diversion by tube choledochoureterostomy has been devised for the purpose of studying the role of bile in the intestinal absorption of drugs. This method was used in six dogs. No technical difficulties or major complications developed, as are inevitable with alternative methods, including external fistula. © 1990 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted

An inexpensive economical solar heating system for homes

A low-cost solar home heating system to supplement existing warm-air heating systems is described. The report is written in three parts: (1) a brief background on solar heating, (2) experience with a demonstration system, and (3) information for the homeowner who wishes to construct such a system. Instructions are given for a solar heating installation in which the homeowner supplies all labor necessary to install off-the-shelf components estimated to cost $2,000. These components, which include solar collector, heat exchanger, water pump, storage tank, piping, and controls to make the system completely automatic, are available at local lumber yards, hardware stores, and plumbing supply stores, and are relatively simple to install. Manufacturers and prices of each component used and a rough cost analysis based on these prices are included. This report also gives performance data obtained from a demonstration system which was built and tested at the Langley Research Center

Tree Buffers

In runtime verification, the central problem is to decide if a given program execution violates a given property. In online runtime verification, a monitor observes a program’s execution as it happens. If the program being observed has hard real-time constraints, then the monitor inherits them. In the presence of hard real-time constraints it becomes a challenge to maintain enough information to produce error traces, should a property violation be observed. In this paper we introduce a data structure, called tree buffer, that solves this problem in the context of automata-based monitors: If the monitor itself respects hard real-time constraints, then enriching it by tree buffers makes it possible to provide error traces, which are essential for diagnosing defects. We show that tree buffers are also useful in other application domains. For example, they can be used to implement functionality of capturing groups in regular expressions. We prove optimal asymptotic bounds for our data structure, and validate them using empirical data from two sources: regular expression searching through Wikipedia, and runtime verification of execution traces obtained from the DaCapo test suite

Abstract Argumentation / Persuasion / Dynamics

The act of persuasion, a key component in rhetoric argumentation, may be viewed as a dynamics modifier. We extend Dung's frameworks with acts of persuasion among agents, and consider interactions among attack, persuasion and defence that have been largely unheeded so far. We characterise basic notions of admissibilities in this framework, and show a way of enriching them through, effectively, CTL (computation tree logic) encoding, which also permits importation of the theoretical results known to the logic into our argumentation frameworks. Our aim is to complement the growing interest in coordination of static and dynamic argumentation.Comment: Arisaka R., Satoh K. (2018) Abstract Argumentation / Persuasion / Dynamics.

Dietary supplementation by older adults in southern China: a hospital outpatient clinic study

<p>Abstract</p> <p>Background</p> <p>There has been little knowledge about dietary supplementation by the Chinese elderly. The aim of this cross-sectional study was to investigate the usage of dietary supplements by older adults in southern China.</p> <p>Methods</p> <p>A total of 600 community-dwelling older adults were recruited from the outpatient clinics of three major hospitals in Foshan city between July 2007 and July 2008. Face-to-face interviews of participants were conducted to obtain information on demographics, lifestyle and dietary supplements use. Frequency and duration of usage were recorded for six categories of dietary supplements.</p> <p>Results</p> <p>Among the 446 consented participants (241 men and 205 women) who were over 55 years of age, 19.1% consumed one or more types of dietary supplements. The prevalence of usage was significantly higher (p = 0.008) for females (24.4%) than for males (14.5%). Dietary supplements were more likely to be consumed by non-smokers (p = 0.021) and those with hyperlipidemia (p = 0.003). The most popular supplement among users was calcium (53%). The majority (71%) of the users consumed supplements on a regular basis at one or more times per day, with an average duration of 2.95 (SD 4.80) years.</p> <p>Conclusion</p> <p>The overall prevalence of dietary supplementation in this older Chinese population was considerably lower than those in other Asia-Pacific countries.</p
