A study to expose quail eggs for two different periods of incubation with low-intensity magnetic flooding on the growth of chicks and their productive performance

An experiment was conducted in the fields of the poultry unit - Livestock Division - Nineveh Research Department, to find out the effect of using low-intensity magnetic flux (110 Gaos) in two periods of incubate quail eggs, on the growth and production performance of the resulting birds, the results showed a significant increase (P ≤0.05) for the magnetic flux treatment on control treatment for hatchability% and fertility%, the percentage of dead embryos decreased significantly (P ≤0.05) for the second exposure period treatment than the control treatment, the two magnetic exposure treatments were significantly superior (P ≤ 0.05) to control treatments in the body weight at one and four weeks age (g), weight gain (g) and food conversion ratio (g/g). The magnetic exposure treatment also achieved a significant decrease (P ≤0.05) for the number of days to reach sexual maturity (or the days to obtain 5% egg production) and for food consumed / kg. The two magnetic treatments were also significantly superior in food conversion ratio (kg feed / kg egg) for the eight-week period of egg production.
LONG-TERM HEPATOTOXICITY AND HYPOGLYCAEMIC STUDY OF AQUEOUS EXTRACTS OF CARICA PAPAYA LEAVES ON NORMAL RABBITS

The use of Carica papaya extracts as an anti-diabetic remedy in Nigeria is well documented. Since these extracts are usually taken for long periods of time, it is important to assess their long term biochemical effects so as to ascertain their safety. In this study, the effects of aqueous extracts of C. papaya leaves, orally administered daily at 200mg/Kg body weight, on body weight, blood glucose and liver function tests of normal rabbits were observed at preset times in the serum for 24 weeks, and in the tissues. Administration of C. papaya aqueous leave extracts caused significant (p<0.05) reductions in body weight and fasting blood glucose levels for the 24 weeks of monitoring. The parameters used to assess liver function (alanine transaminase [ALT], aspartate transaminase [AST], alkaline phosphatase [ALP], gamma glutamyl transferase [γ-GT], total and direct bilirubin) revealed that the administration of C. papaya extracts caused an initial toxic response from the liver, as well as, bile duct obstruction, that were transient and not severe. Since the hypoglycaemic effects of C. papaya was again established by this study, further studies to harness the therapeutic effects and reduce the negative side effects are required; long term consumption of the extracts should be closely monitored by a physician.
Potts models on hierarchical lattices and renormalization group dynamics: II. Examples and numerical results

We obtain the exact renormalization map and plots of Lee–Yang and Fisher zeros distributions for Potts models on a number of hierarchical lattices: the diamond hierarchical lattice, a lattice we call spider web, the Sierpinski gasket and cylinders. Such models are only examples among those we can study in the general framework of hierarchical lattices, developed in a previous paper.

This paper describes in detail the acrylic vessels used to encapsulate the target and gamma catcher regions in the Daya Bay experiment's first pair of antineutrino detectors. We give an overview of the design, fabrication, shipping, and installation of the acrylic vessels and their liquid overflow tanks. The acrylic quality assurance program and vessel characterization, which measures all geometric, optical, and material properties relevant to ν̄e detection at Daya Bay are summarized. This paper is the technical reference for the Daya Bay acrylic vessels and can provide guidance in the design and use of acrylic components in future neutrino or dark matter experiments.
Safety Climate of Ab-Initio Flying Training Organizations: The Case of an Australian Tertiary (Collegiate) Aviation Program

A healthy safety culture is essential to the safe operation of any aviation organization, including flight schools. This study aimed to assess the safety climate of an Australian tertiary (collegiate) aviation program using a self-constructed instrument. Factor analysis of the instrument identified four safety themes, which are Safety Reporting Culture, Safety Reporting Procedure, Organizational Culture and Practice, and General Safety Knowledge. The responses of student pilots suggested that the overall safety climate of the subject flight training academy was healthy at the time of the survey. Further analyses found that perceptions of students of different year groups on Reporting Culture and Organizational Culture and Practices were significantly different from each other, with the first-year students responding more positively. Besides addressing the safety climate of the subject flight training academy, this study also provided a template and a benchmark for other tertiary (collegiate) aviation programs to assess their own safety climate.
Automated Validation and Interpolation of Long-Duration Bicycle Counting Data

Bicycle flow data is crucial for transportation agencies to evaluate and improve cycling infrastructure. Average annual daily bicyclists (AADB) is commonly used in research and practice as a metric for cycling studies such as ridership analysis, infrastructure planning, and injury risk. AADB is estimated by averaging the daily cyclist totals measured throughout the year using a long-term automated bicycle counter, or by using long-term bicycle counting data to extrapolate data from a short-term counting site. Extrapolation of a short-term bicycle counting site requires an accurate and complete set of daily factors from a group of references: long-term bicycle counters. In practice, validation of reference data is done manually, an exercise that is time-consuming but crucial as significant error can be introduced into AADB extrapolation if reference data are not validated. This paper proposes an automated method to validate long-term bicycle count data and interpolate anomalous portions of data. As part of this work, the methods are validated using a relatively large dataset of automated bicycle counts. For validation of our approach, data anomalies are created artificially in a way that removes data (first trial), or reduces counts to 25% or 40% of the measured bicycle counts (second and third trials), for 6 hours, 12 hours, and full days. Of the more than 100 generated anomalies, the validation process flagged approximately 90% in the first and second trials and 80% in the third trial. The average absolute relative error of the interpolated daily values was approximately 10% for all three trials.
A 3.3-to-25V all-digital charge pump based system with temperature and load compensation for avalanche photodiode cameras with fixed sensitivity

This paper presents a digitally controlled charge pump (DCP) to supply high voltages, while ensuring temperature and load current independence of excess bias in cameras based on avalanche photodiodes. This is achieved through a single-photon avalanche diode (SPAD) based monitoring mechanism that continuously reconfigures the DCP using a feedback loop to compensate breakdown voltage variations by temperature and load current in real time. The sensitivity of the SPADs, or photon detection probability (PDP), is maintained to within 1.9% when the temperature shifts from 28°C to 65°C and the load current changes from 0 μA to 100 μA.
24-hours wind speed forecasting and wind power generation in La Serena (Chile)

This article presents 24-h wind speed forecasting for the city of La Serena in Chile and a methodology to explore forecasting effects on the production of wind turbine power. To that end, we used meteorological data from a weather station located in the southern zone of the hyper-arid Atacama Desert. In this area, energy resources are economically and environmentally important, and wind speed forecasting plays a vital role in the management and marketing processes of wind potential via wind farms. To contribute to the development of this energy, we propose carrying out the short-term prediction of 12 and 24 h ahead (identified as Ws(t + 12) and Ws(t + 24), respectively) using an artificial neural network with backpropagation approach. Hourly time series of wind speed, temperature, and relative humidity (from 2003 to 2006) were considered to characterize the artificial neural network in the training phase, while we used data from the year 2007 to check the efficiency of our prediction. For artificial neural network Ws(t + 12) and Ws(t + 24) models, we obtained similar performance of wind speed prediction with root mean square error of around 0.7 m s−1 and with maximum and minimum residuals of +4 and ‒4 m s−1, respectively. Based on the results, we gain a reliable tool to characterize wind speed properties in the range of 1 day within 20% of uncertainty. Moreover, this tool becomes useful to study the effects of our artificial neural network Ws(t + 12) and Ws(t + 24) models on the generation of wind energy from a wind power turbine parametrization.
The epidemiology of ANCA associated vasculitis in Olmsted County, Minnesota (USA): a 20 year population-based study

Objective To estimate the incidence, prevalence and mortality of ANCA-associated vasculitis (AAV) and its subsets, granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic GPA (EGPA), in a U.S. based adult population. Methods All medical records of patients with a diagnosis or suspicion of AAV in Olmsted County, Minnesota from January 1, 1996 to December 31, 2015 were reviewed. Incidence rates were age- and sex-adjusted to the 2010 US white population. Age- and sex-adjusted prevalence was calculated on January 1, 2015. Survival rates were compared with expected rates in the Minnesota population. Results Of 58 incident cases of AAV, 23 (40%) were GPA, 28 (48%) MPA, and 7 (12%) EGPA. Overall, 28 (48%) were women, 57 (98%) were Caucasian, with a mean±SD age at diagnosis of 61.1±16.5 years. Thirty-four patients (61%) were MPO-ANCA and 17 (30%) were PR3-ANCA positive; 5 (9%) were ANCA-negative. The annual incidence of AAV was 3.3/100,000 population (95%CI:2.4-4.1). GPA, MPA and EGPA incidence was 1.3 (95%CI:0.8-1.8), 1.6 (95%CI:1.0-2.2), and 0.4 (95%CI:0.1-0.6), respectively. Overall prevalence of AAV was 42.1/100,000 (95%CI:29.6-54.6). Mortality for AAV overall, and EGPA, MPA and MPO-ANCA was increased (p<0.05); mortality of GPA, PR3-ANCA and ANCA-negative patients did not differ from general population. Conclusion The annual incidence of AAV in Olmsted County is 3.3/100,000, with prevalence of 42.1/100,000, substantially higher than reported in other areas worldwide. The incidence of GPA and MPA is similar. Mortality of MPA and EGPA, but not GPA, is higher than the general population; MPO-ANCA is a marker of poor survival. This article is protected by copyright.

Biomechanics of smart wings in a bat robot: morphing wings using SMA actuators

This paper presents the design of a bat-like micro aerial vehicle with actuated morphing wings. NiTi shape memory alloys (SMAs) acting as artificial biceps and triceps muscles are used for mimicking the morphing wing mechanism of the bat flight apparatus. Our objective is twofold. Firstly, we have implemented a control architecture that allows an accurate and fast SMA actuation. This control makes use of the electrical resistance measurements of SMAs to adjust morphing wing motions. Secondly, the feasibility of using SMA actuation technology is evaluated for the application at hand. To this purpose, experiments are conducted to analyze the control performance in terms of nominal and overloaded operation modes of the SMAs. This analysis includes: (i) inertial forces regarding the stretchable wing membrane and aerodynamic loads, and (ii) uncertainties due to impact of airflow conditions over the resistance–motion relationship of SMAs. With the proposed control, morphing actuation speed can be increased up to 2.5 Hz, being sufficient to generate lift forces at a cruising speed of 5 m s−1.
Prospects for observation of neutrino-nuclear neutral current coherent scattering with two-phase Xenon emission detector

We propose to detect and to study neutrino neutral current coherent scattering off atomic nuclei with a two-phase emission detector using liquid xenon as a working medium. Expected signals and backgrounds are calculated for two possible experimental sites: the Kalinin Nuclear Power Plant in the Russian Federation and the Spallation Neutron Source at the Oak Ridge National Laboratory in the U.S.A. Both sites have advantages as well as limitations. The experiment looks feasible at either location.
Aeromechanical Challenges of Shrouded Low Pressure Turbines for Geared Turbofan Engines

The primary scope of this thesis is to contribute to meeting the challenges associated to the integration of shrouded blades into high speed low pressure turbines of geared turbofan engines. Doubling the rotational speed of the low pressure shaft bears considerable advantages in terms of the fuel consumption, the noise emissions, the length as well as the part count compared to conventional multi-spool engine designs. However, the quadratic increase of the centrifugal blade stress with rotational speed has impeded the application of shrouded low pressure turbine blades, which are aerodynamically more favorable and have a higher robustness against flutter instabilities, in current designs due to high cycle fatigue concerns. As a consequence of the reduced error margin in the fatigue design of high speed blade rows, two immediately arising questions for the design of the next generation of geared turbofan engines are addressed in this work: How accurately can current industrial methods predict the unsteady aerodynamic forces in a shrouded low pressure turbine? And: At what performance cost can the mass of a shroud be reduced by platform cutbacks to mitigate fatigue issues? The current work was carried out within the scope of a joint academic and industrial research effort to elucidate the aerodynamic forcing in a fully shrouded low pressure turbine experimentally and numerically as well as to determine the performance deterioration of different shroud platform geometries. The latest, optimized and tested design of a 1.5-stage fully shrouded low pressure turbine with non-axisymmetric enwalls operating with rim seal purge flow injection represents the baseline for both campaigns. A modular, high resolution and low noise, multipurpose telemetry system has been developed and integrated into the axial research turbine facility “LISA” at ETH Zurich. A unique experimental data set comprised of fast response traverse and wall pressure measurements has been acquired. The unsteady surface pressure of both the rotor as well as the second stator has been probed using a total of 60 flush-mounted, ultra-miniature size, piezo-resistive pressure transducers. The aerodynamic forcing functions and the turbine performance have been characterized using a combination of multi-hole pneumatic probe and fast response aerodynamic probe (FRAP) measurements on the inter-row planes. Leakage flows have been tracked using the unsteady entropy probe (FENT). The comparison of the experimental data with time-accurate RANS simulations highlights the capabilities and limitations of commercial solvers and enables the quantification of the prediction error in the aerodynamically induced blade root stress. The unsteady rotor surface pressure in a shrouded, subsonic low pressure turbine is driven by convective perturbations and acoustic interaction. Five main forcing functions have been identified: Potential interaction with upstream and downstream rows, convective inflow perturbations and incidence variation in the main

A high-performance PMOSFET based on silicon material of hybrid orientation is obtained. Hybrid orientation wafers, integrated by (100) and (110) crystal orientation, are fabricated using silicon-silicon bonding, chemical mechanical polishing, etching silicon and non-selective expitaxy. A PMOSFET with W/L = 50 μm/8 μm is also processed, and the measured results show that the drain-source current and peak mobility of the PMOSFET are enhanced by up to 50.7% and 150% at Vgs = −15 V and Vds = −0.5 V, respectively. The mobility values are higher than that reported in the literature.

Slow-wave coplanar waveguides based on inductive and capacitive loading and application to compact and harmonic suppressed power splitters

In this paper, a slow-wave transmission line implemented in coplanar waveguide technology, based on simultaneous inductive and capacitive loading, is presented for the first time. The shunt capacitors are achieved by periodically etching transverse strips in the back substrate side, connected to the central strip through metallic vias. The series inductors are implemented by etching rectangular slots in the ground plane. The effect of these reactive elements is an enhancement of the effective shunt capacitance and series inductance of the line, leading to a significant reduction of the phase velocity (slow-wave effect). Consequently, the guided wavelength is also reduced, and these lines can be applied to the miniaturization of microwave components. Moreover, due to periodicity, these artificial lines exhibit stop bands (Bragg effect) useful for spurious or harmonic suppression. A compact harmonic suppressed power splitter, based on a slow wave 35.35 Ω impedance inverter, has been designed and fabricated in order to demonstrate the potential of the proposed approach. The length of the inverter is 48% the length of the conventional counterpart, and measured power splitting at the first (3f0) and second (5f0) harmonic frequencies is rejected more than 49 and 23 dB, respectively.
Can perception be extended to a “feel of north”? Tests of automaticity with the NaviEar

This study investigated the potential for the development of novel perceptual experiences through sustained training with a sensory augmentation device. We developed (1) a new geomagnetic sensory augmentation device, the NaviEar, and (2) a battery of tests for automaticity in the use of the device. The NaviEar translates head direction toward north into continuous sound according to a “wind coding” principle. To facilitate automatization of use, its design is informed by considerations of the embodiment of spatial orientation and multi-sensory integration, and it uses a sensory coding scheme derived from means for auditory perception of wind direction that is common in sailing because it is easy to understand and use. The test battery assesses different effects of automaticity (interference, rigidity of responses, and dynamic integration) assuming that automaticity is a necessary criterion to show the emergence of perceptual feel, that is, an augmented experience with perceptual phenomenal quality. We measured performance in simple training tasks, administered the tests for automaticity, and assessed subjective reports through a questionnaire. Results suggest that the NaviEar is easy and comfortable to use and has a potential for applications in real-world situations. Despite high usability, however, a 5-day training with the NaviEar did not reach levels of automaticity that are indicative of perceptual feel. We propose that the test battery for automaticity may be used as a benchmark test for iterative research on perceptual experiences in sensory augmentation and sensory substitution.
INFLUENCE OF INFORMATION LITERACY SKILLS ON USE OF WEB 2.0 TECHNOLOGIES BY STUDENTS IN TWO MONOTECHNICS IN OYO STATE, NIGERIA

This study investigated influence of information literacy skills on web 2.0 technologies use by students in two monotechnics in Oyo State Nigeria using descriptive survey design of correlational type. Four (4) research questions were raised; one (1) research hypothesis that was tested at 0.5 level of significance was formulated. The population of the study comprised two monotechnics (Federal College of Forestry (FCF) and Federal College of Animal Health and Production (FCAHP). With the use of structured questionnaire, data was collected from samples of 273 respondents that were purposively selected with aid of sampling frame. Simple frequency count of percentage distribution in table was used to present the demographic information and as well answer the research questions, while Pearson’s correlation and multiple regression analysis were used to test the hypotheses. The results revealed that respondents in both monotechnics had skills in using Web 2.0 technologies. Most of the respondents regularly used Web 2.0 technologies for personal development, research and project writing. Meanwhile, slow internet network, erratic power supply, and lack of information literacy skills were the main barriers to the use of Web 2.0 technologies by the respondents. The results showed that there was a significant positive correlation between Information Literacy Skills and use of Web 2.0 technologies (r= .259; df = 110; p < 0.05) in FCF and (r= .167; df = 158; p < 0.05) in FCAHP. Recommendations were made to both the monotechnics administrators and students.
