    Integrated lift/drag controller for aircraft

    Get PDF
    A system for altering the lift/drag characteristics of powered aircraft to provide a safe means of glide path control includes a control device integrated for coordination action with the aircraft throttle. Such lift/drag alteration devices as spoilers, dive brakes, and the like are actuated by manual operation of a single lever coupled with the throttle for integrating, blending or coordinating power control. Improper operation of the controller is inhibited by safety mechanisms

    Integrated flight controller for light aircraft

    Controller-throttle engages spoiler/dive brake system when throttle setting is below a fixed power setting and gradually increases effect of spoiler/dive brake as throttle is moved toward idle position; since action is automatically reversible, a sudden application of power abruptly terminates aerodynamic effects of spoiler/dive brake system

    Girl I\u27ll Call My Sweetheart Must Look Like You

    [Verse 1] Now while oft Iā€™ve been wandering, sad and alone, Iā€™ve just dreamed, dreamed, dreamed Of a pair of blue eyes that delightfully shone, and how grand they seemā€™d! They would stare at me, glare at me, try to console, and what could I do? When at times they would look into my very soul and say: ā€œI love you.ā€ [Chorus] The girl Iā€™ll call my sweetheart must have eyes of Irish blue, And her cheeks must blush like roses fondly kissā€™d by morning dew. She must vow to love me truly, And love old Ireland too; For the girl Iā€™ll call my sweetheart must look like you. [Verse 2] All around me they now cast their sweet magic spell under moon or sun, And Iā€™m longing my story of true love to tell to the only one. Sure, today such a beautiful vision Iā€™ve seen of a sweet colleen; I believe that I soon will be claiming the hand of my Fairy queen. [Chorus

    Sweet Girl of My Dreams

    [Verse 1] Oā€™er yonder where lilacs so fair scent the air Sweetly there I was weary and so worn from care. That I lay down to rest midst that fragrance so rare ā€˜Twas then of a maiden I dreamed, Sweetly dreamed And it seemed That at last my poor heart was redeemed While the stars and the moon brightly gleamed. [Refrain] Oh! Sweet girl of my dreams you have beauty so rare. Cheeks that resemble the roses so fair, Your eyes love, sparkle your smile brightly beams. To you Iā€™m singing sweet girl of my dreams, To you Iā€™m singing sweet girl of my dreams. [Verse 2] The rose that is blooming today Light and gay By the way By the morrow may wither away. Leaving naught on its stem but a sign of decay But the love that Iā€™d give dear to you Will be true Eyes of blue It will blossom in loveā€™s brightest hue And flourish in lifeā€™s golden dew. [Refrain

    Enigmatic Red Beds Exposed at Point of Rocks, Cimarron National Grassland, Morton County, Kansas: Chronostratigraphic Constraints from Uranium-Lead Dating of Detrital Zircons

    Point of Rocks, a high-relief bluff overlooking the Cimarron River valley in Morton County, Kansas, is capped by distinct white beds of Neogene Ogallala Formation calcrete that overlie red beds of shale, siltstone, and sandstone. These unfossiliferous red beds are currently assigned to the Jurassic System; however, their age has long been debated due to a lack of marker beds, index fossils, and nearby correlative outcrops. As a result, geologists over the years have assigned the rocks to systems ranging from the Permian to the Cretaceous. In this study, four stratigraphic sections were measured in the red beds and three bulk samples were collected to determine the uranium-lead age distributions of detrital zircon (DZ) populations. Red-bed strata composed of fissile shale and sandstone are interpreted as alluvial overbank deposits, while dominantly trough cross-bedded and planar-laminated sandstones are interpreted as tidally influenced fluvial deposits. Detrital zircon age peaks can be grouped into at least seven subpopulations with a youngest single zircon age of 263.8 Ā± 12.1 Ma, a more conservative age of 293.0 Ā± 6.95 Ma based on the youngest grouping of three grain ages overlapping at 2Ļƒ, and a complete absence of Mesozoic age zircons. In addition, copper oxides along partings and fractures suggest that the red beds once hosted copper sulfides, a common constituent of regional Permian-Triassic red beds. The DZ data--in conjunction with the identification of the Permian Day Creek Dolomite marker bed in logs of nearby drilling tests--strongly suggest that the enigmatic red beds cropping out at the base of Point of Rocks should be assigned to the Guadalupian Big Basin Formation, the uppermost Permian unit in Kansas

    Why dictators veto: legislation, legitimation and control in Kazakhstan and Russia

    Why do authoritarian presidents still use their legislative power? Although recent studies have argued that authoritarian legislatures are more than ā€œrubberstampsā€ and can serve as arenas for elite bargaining over policy, there is no evidence that legislators would pass bills that go against presidential preferences. This article investigates this apparent paradox and proposes a theoretical framework to explain presidential activism in authoritarian regimes. It argues that any bills that contravene constraints on policy-making set by the president should generally be stopped or amended by other actors loyal to the regime. Thus, presidents will rather use their veto (1) to protect the regimeā€™s output legitimacy and stability, and/or (2) to reinforce their power vis-Ć -vis other actors. The argument is tested using two case studies of veto use in Kazakhstan and Russia over the last 10 years. The analysis supports the propositions of the theoretical framework and furthermore highlights the potential use of vetoes as a means of distraction, particularly in relation to international audiences. The article extends research on presidential veto power to authoritarian regimes and its findings contribute to the growing literature on the activities of authoritarian legislatures

    Nitric Oxide-Releasing Nanoparticles Prevent Propionibacterium acnes-Induced Inflammation by Both Clearing the Organism and Inhibiting Microbial Stimulation of the Innate Immune Response.

    Propionibacterium acnes induction of IL-1 cytokines through the NLRP3 (NLR, nucleotide oligomerization domain-like receptor) inflammasome was recently highlighted as a dominant etiological factor for acne vulgaris. Therefore, therapeutics targeting both the stimulus and the cascade would be ideal. Nitric oxide (NO), a potent biological messenger, has documented broad-spectrum antimicrobial and immunomodulatory properties. To harness these characteristics to target acne, we used an established nanotechnology capable of generating/releasing NO over time (NO-np). P. acnes was found to be highly sensitive to all concentrations of NO-np tested, although human keratinocyte, monocyte, and embryonic zebra fish assays revealed no cytotoxicity. NO-np significantly suppressed IL-1Ī², tumor necrosis factor-Ī± (TNF-Ī±), IL-8, and IL-6 from human monocytes, and IL-8 and IL-6 from human keratinocytes, respectively. Importantly, silencing of NLRP3 expression by small interfering RNA did not limit NO-np inhibition of IL-1 Ī² secretion from monocytes, and neither TNF-Ī± nor IL-6 secretion, nor inhibition by NO-np was found to be dependent on this pathway. The observed mechanism by which NO-np impacts IL-1Ī² secretion was through inhibition of caspase-1 and IL-1Ī² gene expression. Together, these data suggest that NO-np can effectively prevent P. acnes-induced inflammation by both clearing the organism and inhibiting microbial stimulation of the innate immune response
