The New Judicial Selection Landscape

Chapter 3 maps the current judicial selection landscape by describing a series of developments decades in the making that has altered the political environment of judicial elections in fundamental ways. The chapter begins with a table showing the breakdown across all fifty U.S. states regarding which of the five methods of selecting judges are used by each state in selecting its high court judges. An additional table demonstrates how each state treats the reselection of a judge after the judge’s initial appointment or election. The chapter then turns to the contributing causes of the new politics of judicial elections, which include the weakening of the Democratic Party in the southern states, the rise of discretionary Supreme Court Review and the decline of mundane cases, the migration of civil rights and civil liberties campaigns to state courts, the role judges play as enemy combatants in the War on Crime, and the battle for tort reform going on in the state courts, which have resulted in the changing landscape of the American judiciary. The chapter concludes with a discussion of the consequences of these changes.

Modeling Contra-Rotating Turbomachinery Components for Engine Performance Simulations: The Geared Turbofan With Contra-Rotating Core Case

This paper presents a method of modeling contra-rotating turbomachinery components for engine performance simulations. The first step is to generate the performance characteristics of such components. In this study, suitably modified one-dimensional mean line codes are used. The characteristics are then converted to three-dimensional tables (maps). Compared to conventional turbomachinery component maps, the speed ratio between the two shafts is included as an additional map parameter and the torque ratio as an additional table. Dedicated component models are then developed that use these maps to simulate design and off-design operation at the component and engine levels. Using this approach, a performance model of a geared turbofan with a contra-rotating core (CRC) is created. This configuration was investigated in the context of the European program “NEW Aero-Engine Core Concepts” (NEWAC). The core consists of a seven-stage compressor and a two-stage turbine without interstage stators and with successive rotors running in the opposite direction through the introduction of a rotating outer spool. Such a configuration results in a reduced parts count, length, weight, and cost of the entire high pressure (HP) system. Additionally, the core efficiency is improved due to reduced cooling air flow requirements. The model is then coupled to an aircraft performance model and a typical mission is carried out. The results are compared against those of a similar configuration employing a conventional core and identical design point performance. For the given aircraft-mission combination and assuming a 10% engine weight saving when using the CRC arrangement over the conventional one, a total fuel burn reduction of 1.1% is predicted.

Changes in macroelement content of rhizomes of Nuphar lutea (L.) Sibith. and Sm. during the annual cycle

This study presents the results of studies on the chemical composition of rhizomes of <em>Nuphar lutea</em> which were carried out from July 2006 to November 2007 (the samples were collected at two-week intervals from March to November 2007). The first indication of the start of the growing season was the growth of leaves in the apical part of the rhizomes. Clearly visible signs that marked the beginning of the growing season were unfolding of leaves, which became arrow-shaped. The leaves had already unfolded and were arrow-shaped (saggitate) on April 10th when the temperature of the bottom water layer was 7^oC. It may be assumed, therefore, that the growing season began between the 28th March and 10th April 2007. The phosphates, nitrates, sodium, calcium, total iron and sulphates levels in the rhizomes declined just after the growing season had started. The total nitrogen content remained at a constant level whereas the amount of dissolved silica increased. Considerable changes in the macroelement contents were noted when <em>Nuphar lutea</em> was in full bloom (10th-24th June). The macroelement contents presented in the tables and diagrams were expressed on a dry matter basis. An additional table illustrates the macroelement contents expressed on a fresh matter basis. The problem of collecting rhizomes of polycormic plants is discussed.

Scale Insects and Mealybugs on Ornamental Plants

Revised! ENY-323, a 6-page illustrated fact sheet by Eileen A. Buss and Jay Cee Turner, describes this group of serious pests of many ornamental plants. Includes sections on biology and behavior; armored scales, soft scales, mealybugs and sooty mold; detecting infestations; and cultural, biological, and chemical control; and tables listing pesticides available for professional use on ornamentals.
