Efficacy of phenothiazine in the treatment of sheep for control of internal parasites
"February, 1946."Treating ewes once in December and once the following March with a full dose of liquid phenothiazine and every 28 days thereafter with 1 1/2 per cent copper sulphate until the following December did not control nodular worm infestation even though at the beginning of the experiment the sheep were placed upon clean pasture.Treating sheep with liquid phenothiazine every four weeks from December to March (giving a total of four treatments) and then giving them 1 1/2 per cent copper sulphate every 28 days did not
control nodular worm infestations. The 1 1/2 per cent copper sulphate solution was found very satisfactory in keeping the lambs free from Haemonchus contortus. Treating sheep with liquid phenothiazine every four weeks from December to early April and then allowing them access to pheno-thiazine-salt mixture (1 part phenothiazine to 10 parts salt) was very satisfactory in controlling nodular worm infestation. This method of handling sheep held the Haemonchus contortus infestation down to an average of about 19 per lamb. This same method of handling did not satisfactorily control ostertagia, nematodirus, cooperia or tapeworms. Whipworm counts were not materially different in any of the three experiments. Average weight of the lambs was very much higher in Experiment III when the sheep had access to phenothiazine and salt mixture than it was in Experiments I and II. Phenothiazine has not been found toxic to sheep either in a 1 to10 phenothiazine-salt mixture or when the medicine has been given as a drench every 28 days throughout the entire year. The use of phenothiazine has not interfered with breeding efficiency. Worm egg counts by the flotation method have not contributed any aid in this study, but would be useful in sheep infested with only one species of parasite or with species that can be definitely identified by microscopic examination alone

The Immature Stages and Natural History of Veladyris pardalis (Salvin, 1869) in Eastern Ecuador (Lepidoptera: Nymphalidae: Lthomiinae)
We describe the immature stages and oviposition behavior of Veladyris pardalis (Salvin, 1869) from northeastern Ecuador. An unidentified species of Solanum (Solanaceae) is the larval food plant. Eggs are laid singly on leaves, stems or epiphytes growing on the host. Veladyris pardalis has four larval stadia, and takes 64–70 days to mature from oviposition to adult
Unconditionally verifiable blind computation
Blind Quantum Computing (BQC) allows a client to have a server carry out a
quantum computation for them such that the client's input, output and
computation remain private. A desirable property for any BQC protocol is
verification, whereby the client can verify with high probability whether the
server has followed the instructions of the protocol, or if there has been some
deviation resulting in a corrupted output state. A verifiable BQC protocol can
be viewed as an interactive proof system leading to consequences for complexity
theory. The authors, together with Broadbent, previously proposed a universal
and unconditionally secure BQC scheme where the client only needs to be able to
prepare single qubits in separable states randomly chosen from a finite set and
send them to the server, who has the balance of the required quantum
computational resources. In this paper we extend that protocol with new
functionality allowing blind computational basis measurements, which we use to
construct a new verifiable BQC protocol based on a new class of resource
states. We rigorously prove that the probability of failing to detect an
incorrect output is exponentially small in a security parameter, while resource
overhead remains polynomial in this parameter. The new resource state allows
entangling gates to be performed between arbitrary pairs of logical qubits with
only constant overhead. This is a significant improvement on the original
scheme, which required that all computations to be performed must first be put
into a nearest neighbour form, incurring linear overhead in the number of
qubits. Such an improvement has important consequences for efficiency and
fault-tolerance thresholds.Comment: 46 pages, 10 figures. Additional protocol added which allows
arbitrary circuits to be verified with polynomial securit
Optical detection of the Pictor A jet and tidal tail : evidence against an IC/CMB jet
Date of Acceptance: 12/06/2015New images of the FR II radio galaxy Pictor A from the Hubble Space Telescope reveal a previously undiscovered tidal tail, as well as a number of jet knots coinciding with a known X-ray and radio jet. The tidal tail is approximately 5″ wide (3 kpc projected), starting 18″ (12 kpc) from the center of Pictor A, and extends more than 90″ (60 kpc). The knots are part of a jet observed to be about 4′ (160 kpc) long, extending to a bright hotspot. These images are the first optical detections of this jet, and by extracting knot flux densities through three filters, we set constraints on emission models. While the radio and optical flux densities are usually explained by synchrotron emission, there are several emission mechanisms that might be used to explain the X-ray flux densities. Our data rule out Doppler-boosted inverse Compton scattering as a source of the high-energy emission. Instead, we find that the observed emission can be well described by synchrotron emission from electrons with a low-energy index (p ∼ 2) that dominates the radio band, while a high-energy index (p ∼ 3) is needed for the X-ray band and the transition occurs in the optical/infrared band. This model is consistent with a continuous electron injection scenario.Peer reviewedFinal Accepted Versio
Flow-Field Investigation of Gear-Flap Interaction on a Gulfstream Aircraft Model
Off-surface flow measurements of a high-fidelity 18% scale Gulfstream aircraft model in landing configuration with the main landing gear deployed are presented. Particle Image Velocimetry (PIV) and Laser Velocimetry (LV) were used to measure instantaneous velocities in the immediate vicinity of the main landing gear and its wake and near the inboard tip of the flap. These measurements were made during the third entry of a series of tests conducted in the NASA Langley Research Center (LaRC) 14- by 22-Foot Subsonic Tunnel (14 x 22) to obtain a comprehensive set of aeroacoustic measurements consisting of both aerodynamic and acoustic data. The majority of the off-body measurements were obtained at a freestream Mach number of 0.2, angle of attack of 3 degrees, and flap deflection angle of 39 degrees with the landing gear on. A limited amount of data was acquired with the landing gear off. LV was used to measure the velocity field in two planes upstream of the landing gear and to measure two velocity profiles in the landing gear wake. Stereo and 2-D PIV were used to measure the velocity field over a region extending from upstream of the landing gear to downstream of the flap trailing edge. Using a special traverse system installed under the tunnel floor, the velocity field was measured at 92 locations to obtain a comprehensive picture of the pertinent flow features and characteristics. The results clearly show distinct structures in the wake that can be associated with specific components on the landing gear and give insight into how the wake is entrained by the vortex at the inboard tip of the flap
