    Beam transfer in the cascade synchrotron

    Get PDF
    The problems of beam transfer from the booster to the main ring of the cascade synchrotron may be divided into two classes. The first consists of problems connected with the physical transfer of the beam from the booster ring to the main ring. These problems are: (a) ejection from the booster ring without deterioration of the optical quality of the beam, (b) transport of the beam to the main ring including lenses for matching the region of phase space occupied by the beam to the region appropriate for the main ring, and (c) injection into the main ring

    \u3ci\u3eFugate v. Ronin\u3c/i\u3e—Criminal Law Jurisdiction of Juvenile Courts in Cases of Juvenile Murder

    Petitioner, a fourteen-year-old girl, was charged with murder in the first degree in the county court of Lancaster County. The county court entered an order that there be a preliminary hearing and the petitioner be held without bail. The youth moved for a transfer of the proceedings against her to the juvenile court on the ground that section 43-2111 imposed a mandatory duty upon a magistrate to transfer the case of a delinquent child under sixteen years of age to the juvenile court. This motion was overruled by the county judge of Lancaster County. The petitioner filed in the district court of Lancaster County a petition for a writ of prohibition prohibiting the county judge from holding a preliminary hearing upon the complaint. From an order of the district court denying the writ of prohibition, the petitioner appealed. Held: The juvenile courts do not have the sole or exclusive jurisdiction of children under eighteen years of age who have violated Nebraska law; the county attorney is not limited by the Juvenile Court Act in his duty to file proper complaints against wrongdoers and prosecute the same; a preliminary hearing on a felony charge is not a case within the meaning of section 43-2112

    Finite Element Solution: Nonlinear Flapping Beams for Use with Micro Air Vehicle Design

    Get PDF
    The development and use of Micro Air Vehicles is becoming more and more important to the military. Size, weight, maneuverability, stealth, and fuel consumption are just some of the constraints on a future Micro Air Vehicle. Perfect blueprints for a small scale flying machine are both insects and humming birds. Medium sized hummingbirds are found to have wings-beats at a frequency of 18-28 Hz. There is a vast amount of complexity to just how these creatures can create lift; however, this study looks at different beams made of common materials with 1st natural bending frequencies in this range. This study documents and evaluates the use of analytical tools to solve for nonlinear characteristics of a system. A function called the backbone curve is incorporated into a MATLAB program. The Hilbert transform characterized by the nonlinear decrement approach captures all of the necessary coefficients for this function. ABAQUS/CAE is relied upon. The numerical finite element results are compared to experiments. This work gives a better understanding of how materials and geometry perform when used in Micro Air Vehicle design considering large displacements

    Bills and Notes—Constructive Acceptance of a Check by Retention

    Get PDF
    A check was drawn on the defendant bank and made payable to the plaintiff. The check was deposited with the X bank for collection and forwarded by X bank to the Y bank. Y bank forwarded the check to the Federal Reserve Bank which sent it by mail to the defendant bank. The defendant bank, upon receipt of the check, marked it “return” because of insufficient funds. The following day Federal bank examiners seized control of the cash items of the bank, and as a consequence the defendant bank was unable to trace and return the check for more than forty-eight hours. Plaintiff, payee, brought suit contending that the defendant bank had accepted the check by its silent holding for more than twenty-four hours. Held, that the failure of the defendant bank to return the check within twenty-four hours after its receipt did not constitute acceptance

    Pentatomidae (Hemiptera: Heteroptera: Pentatomidae) Captured on Purple Prism Traps Deployed for Detection of Emerald Ash Borer (Agrilus planipennis) (Coleoptera: Buprestidae) in Minnesota

    The observation of bycatch from insect trapping programs, though often considered bothersome, may hold value for ecological and taxonomic studies. In Minnesota, a large trapping survey consisting of pheromone-baited purple prism traps, has been conducted for early detection of Agrilus planipennis, the emerald ash borer. Stink bugs (Heteroptera: Pentatomidae), which are pests of increasing importance in the North Central U.S., were observed to be captured by these traps. The objective of this study was to use trap bycatch from the A. planipennis traps for further documentation of the abundance and diversity of Pentatomidae in Minnesota. In 2011 and 2012, 4,401 and 5,651 purple prism traps were deployed and checked in Minnesota, respectively. Across both years, a total of 17 species of Pentatomidae were identified from 2 subfamilies, Asopinae and Pentatominae. The most abundant and prevalent species collected were Banasa calva (Say), B. dimidiata (Say), Chinavia hilaris (Say), Euschistus tristigmus luridus Dallas, Menecles insertus (Say), and Podisus maculiventris (Say). The pentatomid community observed on purple prism traps deployed in arboreal habitats differed from pentatomid communities reported in Minnesota crops (i.e., soybean, wheat and corn). Results of this study show that many pentatomid species are captured on purple prism traps and therefore bycatch of these traps could provide valuable information on the pentatomid community. However, purple prism traps should be used in addition to traditional surveillance or scouting methods for pentatomids

    Using a Primordial Gravitational Wave Background to Illuminate New Physics

    Get PDF
    A primordial spectrum of gravitational waves serves as a backlight to the relativistic degrees of freedom of the cosmological fluid. Any change in the particle physics content, due to a change of phase or freeze-out of a species, will leave a characteristic imprint on an otherwise featureless primordial spectrum of gravitational waves and indicate its early-Universe provenance. We show that a gravitational wave detector such as the Laser Interferometer Space Antenna would be sensitive to physics near 100 TeV in the presence of a sufficiently strong primordial spectrum. Such a detection could complement searches at newly proposed 100 km circumference accelerators such as the Future Circular Collider at CERN and the Super Proton-Proton Collider in China, thereby providing insight into a host of beyond Standard Model issues, including the hierarchy problem, dark matter, and baryogenesis.Comment: 7 pages, 3 figures; added reference

    Fair Use for Nonfiction Authors

    Get PDF
    The Authors Alliance guide to Fair Use for Nonfiction Authors is designed to empower authors to exercise their right to use source materials to further their research and writing goals by helping them to make confident fair use decisions. The guide addresses three common situations faced by nonfiction authors in which fair use may apply: 1) criticizing, discussing, or commenting on copyrighted material; 2) using copyrighted material to support a point made in the author’s work; and 3) using copyrighted material for non-consumptive research. It also addresses the most frequently asked questions about fair use and clears up some common misconceptions about when it might apply
