Supplementation with Agave fourcroydes powder on growth performance, carcass traits, organ weights, gut morphometry, and blood biochemistry in broiler rabbits

The aim of this study was to evaluate the effect of dietary supplementation with Agave fourcroydes powder on growth performance, carcass traits, organ weights, gut morphometry, and blood biochemistry in broiler rabbits. A total of 40 male rabbits (New Zealand × Californian) weaned at 35 d were randomly selected for a control diet (CD) and CD + 1.5% of A. fourcroydes powder, with 10 replicates and two rabbits per replicate. After 60 d, A. fourcroydes powder increased body weight, feed intake, and weight gain (P<0.05), without affecting feed conversion ratio and viability (P>0.05). Furthermore, this natural product did not affect the edible portions and the indicators determined in the Longissimus dorsi, nor the organ relative weights and the intestinal morphometry (P>0.05); however, a decrease in cecal pH was observed and consequently an increase in cecal beneficial bacteria (P<0.05) were found. Also, A. fourcroydes powder reduced (P<0.05) the serum concentration of glucose, harmful lipids, HDL and atherogenic index although without change for the ureic nitrogen, creatinine and VLDL (P>0.05). Agave fourcroydes powder as a zootechnical additive promoted better growth, in addition, it showed lipid-lowering and hypoglycemic effects, without modifying the edible portions and organs digestive.
Inverse grey-box model-based control of a dielectric elastomer actuator

An accurate physical-based electromechanical model of a commercially available tubular dielectric elastomer (DE) actuator has been developed and validated. In this contribution, the use of the physical-based electromechanical model to formulate a model-based controller is examined. The choice of control scheme was dictated by the desire for transparency in both controller design and operation. The internal model control (IMC) approach was chosen. In this particular application, the inverse of the linearized form of the grey-box model is used to formulate the IMC controller. To ensure consistent control performance across the operating range of the DE actuator, a gain scheduling term, which linearizes the operating characteristics of the tubular dielectric elastomer actuator, is developed and implemented in series with the IMC controller. The IMC-based approach is investigated for servo control of the DE actuator position as well as its ability to provide vibration isolation of a payload subject to ground vibration.
Human Adenovirus Species D Interactions with Corneal Stromal Cells

Notable among the many communicable agents known to infect the human cornea is the human adenovirus, with less than ten adenoviruses having corneal tropism out of more than 100 known types. The syndrome of epidemic keratoconjunctivitis (EKC), caused principally by human adenovirus, presents acutely with epithelial keratitis, and later with stromal keratitis that can be chronic and recurrent. In this review, we discuss the current state of knowledge regarding the molecular biology of adenovirus infection of corneal stromal cells, among which the fibroblast-like keratocyte is the most predominant, in order to elucidate basic pathophysiologic mechanisms of stromal keratitis in the human patient with EKC.

Formulation and Simulation of a Field Data Based Model for the Turning Process by using Response Surface Method

This paper shows the clear idea about the detailed methodology of mathematical model formulation and simulation for the surface roughness, tool temperature, and machine vibration and operator pulse rate during the turning process. It helps to develop an accurate and reliable model for predicting and optimizing the critical process parameters which affects the quality, productivity and the safety of the operator during a step turning process. This paper presents response surface methodology ,a new way of modelling based on the best fit surface 3D response curve to analyze the impact of various machining field parameters on the machining of Aluminium 6063,S.S 304,BRASS, EN1A, EN8.In Indian scenario where majority of total machining operation are still executed manually which needs to be focused and develop a mathematical relation which simulate the real input and output data directly from the machining field where the work is actually being executed. The findings indicate that the topic understudy is of great importance as no such approach of field data based mathematical simulation is adopted for the formulation of mathematical model.
Numerical analysis of inhomogeneous Schottky diode with discrete barrier height patches

ABSTRACT The potential profile inside the semiconductor at the metal–semiconductor contact is simulated by numerically solving the Poisson equation and the drift diffusion equations for inhomogeneous Schottky diode. From the simulated potential and the electron and hole concentrations, the drift-diffusion current as a function of bias is calculated. The simulation is carried out for various distribution patterns of barrier height patches at the metal–semiconductor contact to study the effect of barrier inhomogeneities on the Schottky diode parameters, namely barrier height and ideality factor and their temperature dependence. It is found that barrier height decreases and ideality factor increases with increase in the deviation of discrete barrier height patches in the distribution. The resulting barrier parameters are studied to understand the effect of barrier inhomogeneities on the current–voltage characteristics of inhomogeneous Schottky contact.
Transverse mixing in natural streams

The mechanics of mixing of neutral substances in natural streams and methods for engineering applications of the understanding developed to date constitute the subject of this paper.Diffusion and differential advection are identified as the main processes governing mixing in natural streams and are reviewed in some detail. The interaction between these two processes is shown to enhance the rates of spreading in the longitudinal direction and this effect is termed dispersion.Methods for predicting the concentration resulting from injection of a neutral substance in a stream, as a function of time and location, are outlined and the various pertinent simplifications and associated assumptions are discussed. It is shown that in steady-state situations, such as those resulting from continuous releases at constant rate, analytical predictions are possible using a transformation that substitutes distance across the channel by the corresponding fraction of discharge. However, transient mixing, such as that result.
Economic interventions, economic perceptions and political support during the Eurozone crisis

What is the effect of external economic intervention on political support and economic evaluations? We argue that economic interventions systematically worsen support for governing institutions and much of this is mediated through updating economic perceptions, at least during the Eurozone crisis. We evidence this with two analyses. First, we provide the first quasi-experimental evidence to show that intervention worsened both political support and economic evaluations. Second, we conduct a mediation analysis using Eurobarometer data to quantify how much of the effect of intervention is mediated by economic evaluations. This has broader implications for understanding how citizens react to international integration, international cues, and the process of forming judgements of political support.
REFLOODING OF A SEVERELY DAMAGED REACTOR CORE : EXPERIMENTAL ANALYSIS AND MODELLING

In case of severe accident in a nuclear reactor, the fuel rods may be highly damaged and oxidized and finally collapse to form a debris bed. Removal of decay heat from a debris bed is a challenging issue because of the difficulty for water to flow inside. From a safety point of view, it is important to evaluate chances of coolability of the reactor core during a severe accident. This is in line with the safety philosophy of defence in depth which requires to foresee and to analyse all options to stop an accident at any stage. Currently, the French IRSN has started two experimental programs, PRELUDE and PEARL, to investigate the physical phenomena during a reflood process at high temperature and to provide relevant data in order to improve predictive models. From a selection of experimental results, a reflooding model was improved and validated. The model is implemented in the code ICARE-CATHARE developed by IRSN which is used for severe accident reactor analysis.
Geobotanical Study of Some Areas South-Western Mosul by using Remote Sensing and ASD Dataset

To investigate the health of vegetation and soil purity in some areas southwestern Mosul city, multi spectral remote sensing and Analytical Spectral Device (ASD) field spectrometer were used. Landsat ETM+ image was used to identify tonal spectral anomaly after correct it spectrally by using ENVI’s FLAASH method. A combination of False color composite image (FCC) based on the spectral characteristics of vegetation and soils was selected. This combination consists of (Band7-Red, Band4-Green, Band1-Blue) and also used to express the subtle grey tones as color variations and then some of anomalous reflectivity zones were extracted. Field spectral measurements were applied to determine the spectral reflectance anomaly of vegetation and soils. The spectral measurements of the samples were made in spectral analysis laboratory at (Remote Sensing CenterMosul University) on a number of samples with a full-range of ASD spectrometer (i. e. 350m to 2500m), both on and off the anomalous spectral zones in order to compare the spectral changes between them. The results confirmed to the existing these reflectance zones by determination an increase in the reflectance at the chlorophyll absorption as well as a shift in the position of the red edge. The results also have indicated that the anomalous relationship between the occurrence of hydrocarbon seepages and anomaly reflectance zones. In this context, the migration of hydrocarbons has a predominantly structural control, related to the listric fault and accompanying fractures.
Simulation of MEMS Capacitive Thermal Sensor Based on Tip Deflection of a Functionally Graded Micro-Beam

This work presents a simulation study on a novel micro thermal sensor to evaluate a different range of temperature. Micro Electro Mechanical Systems (MEMS) technology is an interesting field in mechanics andmetrology. In this work, a capacitive micro thermal sensor based on tip deflection of Functionally Graded Micro-beam (FGM) was designed. The thermo-electric mechanical equations based on Euler-Bernoulli beam theory were derived and solved using step-by-step linearization method. The increase in temperature was expressed with respect to the changes in the capacitance. The beam deflections were compared with the existing results showing good conformity with the highest error obtained as 4.3% at 65°C.
The Integration of Wheelchair Users in Team Handball

Thus far, there are only a few sports activities in which people with and without intellectual disabilities can participate together and on an equal footing. The situation is even more complicated when people who are dependent on a wheelchair want to take part. The sports project Freiwurf Hamburg aims to make team handball playable for everyone. This case study documents how this can be achieved with a modified version of the handball game for runners and wheelchair users. Qualitative and quantitative data are collected and evaluated. The results show that players tend to distinguish between the roles of runner and wheelchair user rather than between disabled and non-disabled.
Characterization and modeling of nonlinear trapping effects in power SiC MESFETs

Trapping effects in power SiC MESFETs are investigated using a pulsed I-V pulsed S-parameters measurement system. It is shown that the main effect comes from substrate (buffer) traps sensitive to the drain-source voltage. Moreover a nonlinear model of the trapping phenomenon, taking into account the electron capture and emission with different time constants allows one to predict experimentally observed I-V and RF power performances of the devices.
Three‐dimensional VS profiling using microtremors in Kushiro, Japan

A practical method is presented for determining three‐dimensional S‐wave velocity (VS) profile from microtremor measurements. Frequency–wave number (f–k) spectral analyses of microtremor array records are combined, for this purpose, with microtremor horizontal‐to‐vertical (H/V) spectral ratio techniques. To demonstrate the effectiveness of the proposed method, microtremor measurements using arrays of sensors were conducted at six sites in the city of Kushiro, Japan. The spectral analyses of the array records yield dispersion characteristics of Rayleigh waves and H/V spectra of surface waves, and joint inversion of these data results in VS profiles down to bedrock at the sites. Conventional microtremor measurements were performed at 230 stations within Kushiro city, resulting in the H/V spectra within the city. Three‐dimensional VS structure is then estimated from inversion of the H/V spectra with the VS values determined from the microtremor array data. This reveals three‐dimensional VS profile of Kushiro city, together with an unknown hidden valley that crosses the central part of the city. The estimated VS profile is consistent with available velocity logs and results of subsequent borings, indicating the effectiveness of the proposed method. Copyright © 2008 John Wiley & Sons, Ltd.
Aerodynamic Design Analysis of the HEXAFLY-INT Hypersonic Glider

This paper deals with the aerodynamic performance analysis of the expendable Experimental Flight Test Vehicle under development in the seventh framework programme, namely HEXAFLY-INT. A mission scenario, the different flight segments and events to which the payload is exposed to are described and justified. This allowed the definition of the aerothermo-mechanical loads required to conceptually design all elements on board of the vehicle. This flying test bed is a self-controlled glider configuration that shall face a hypersonic flight starting at about Mach 8, just after the separation from the experimental support module at about 50 km altitude, up to vehicle loss. During this flight, several experiments shall be carried out. The appraisal of the vehicle aerodynamic performance is needed for Flight Mechanics and Guidance, Navigation and Control analysis. In particular, hinge line moments for the EFTV’s aileron are also addressed to design the actuation line and to select the actuator device itself. The vehicle made maximum use of databases, expertise, technologies and materials elaborated in previously European community co-funded projects ATLLAS I & II, LAPCAT I & II, and HEXAFLY.
Long-Read RNA Sequencing Identifies Polyadenylation Elongation and Differential Transcript Usage of Host Transcripts During SARS-CoV-2 In Vitro Infection

Better methods to interrogate host-pathogen interactions during Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infections are imperative to help understand and prevent this disease. Here we implemented RNA-sequencing (RNA-seq) combined with the Oxford Nanopore Technologies (ONT) long-reads to measure differential host gene expression, transcript polyadenylation and isoform usage within various epithelial cell lines permissive and non-permissive for SARS-CoV-2 infection. SARS-CoV-2-infected and mock-infected Vero (African green monkey kidney epithelial cells), Calu-3 (human lung adenocarcinoma epithelial cells), Caco-2 (human colorectal adenocarcinoma epithelial cells) and A549 (human lung carcinoma epithelial cells) were analysed over time (0, 2, 24, 48 hours). Differential polyadenylation was found to occur in both infected Calu-3 and Vero cells during a late time point (48 hpi), with Gene Ontology (GO) terms such as viral transcription and translation shown to be significantly enriched in Calu-3 data. Poly(A) tails showed increased lengths in the majority of the differentially polyadenylated transcripts in Calu-3 and Vero cell lines (up to ~136 nt in mean poly(A) length, padj = 0.029). Of these genes, ribosomal protein genes such as RPS4X and RPS6 also showed downregulation in expression levels, suggesting the importance of ribosomal protein genes during infection. Furthermore, differential transcript usage was identified in Caco-2, Calu-3 and Vero cells, including transcripts of genes such as GSDMB and KPNA2, which have previously been implicated in SARS-CoV-2 infections. Overall, these results highlight the potential role of differential polyadenylation and transcript usage in host immune response or viral manipulation of host mechanisms during infection, and therefore, showcase the value of long-read sequencing in identifying less-explored host responses to disease.
Risk Factors for CMV Viremia and Treatment-Associated Adverse Events Among Pediatric Hematopoietic Stem Cell Transplant Recipients

Abstract Background Cytomegalovirus (CMV) causes substantial morbidity and mortality after hematopoietic stem cell transplantation (HSCT). There are limited data on risk factors for CMV viremia and the safety of antiviral medications used to treat CMV in children. Methods We conducted a single-center retrospective study of children who underwent HSCT between 2000 and 2016. We used log-logistic regression to evaluate associations between clinical characteristics and CMV-free survival at 100 days after HSCT. We compared the incidences of laboratory-defined adverse events (AEs) during treatment with ganciclovir and foscarnet. Results Among 969 children, the median (interquartile range) age was 6.5 (3.1–11.5) years, and 80% underwent allogeneic HSCT. Two hundred forty-four (25%) children developed CMV viremia. Older age (odds ratio [OR], 0.95; 95% CI, 0.92–0.98), male sex (OR, 0.71; 95% CI, 0.51–0.99), non-Black, non-White race (OR, 0.56; 95% CI, 0.36–0.87), umbilical cord blood donor source (OR, 0.28; 95% CI, 0.08–0.97), and CMV seropositivity (R-/D+: OR, 0.17; 95% CI, 0.07–0.41; R+/D-: OR, 0.14; 95% CI, 0.09–0.21; R+/D+: OR, 0.08; 95% CI, 0.04–0.15) were associated with lower odds of 100-day CMV-free survival. Compared with foscarnet, ganciclovir was associated with lower incidences of thrombocytopenia (incidence rate ratio [IRR], 0.38; 95% CI, 0.15–0.97), electrolyte AEs (IRR, 0.42; 95% CI, 0.24–0.75), endocrine AEs (IRR, 0.52; 95% CI, 0.34–0.79), and renal AEs (IRR, 0.36; 95% CI, 0.19–0.65). Conclusions CMV viremia occurred commonly among children after HSCT, and ganciclovir and foscarnet were associated with distinct toxicity profiles among children with CMV infection. These findings should be considered when developing CMV prevention and treatment strategies for children after HSCT.
Fatigue Tests on Buried or Repaired Dented Steel Pipeline Specimens

This paper presents the results of fatigue tests performed on dented steel pipeline specimens that were tested under different environmental conditions and subjected to cyclic internal pressure. Thirty-three pipe specimens were divided into three groups and tested under three different conditions. A first set of nine dented specimens was tested in air without any restrictions. A second set of eight specimens was tested while buried in the soil. A third set of sixteen specimens was tested in air, after the dents had been repaired by composite material sleeves. Hot-spot cyclic strain amplitudes were measured using two experimental techniques: Digital Image Correlation (DIC) and Fiber Optic Bragg Strain Gauges (FBSG). At first, all thirty-three specimens were tested in air along five full cycles in order to carry out full-field measurements using DIC to identify and quantify strain concentration at sites that were potential locations for fatigue cracks to initiate. Close to these point-locations, measurements of strains using FBSG were also made, and the results were then compared with the DIC results. FBSG were also used during the cyclic pressure loading process while the specimens were being tested, in such a way as to monitor the influence of the environment in the dented areas. The test results demonstrated that a simple uniaxial Manson-Coffin fatigue equation that uses the universal exponents proposed by Manson, together with the circumferential strain amplitude measured at the hot spots can be used to predict the fatigue life of the dented specimens. Moreover, it was determined that the measured strains at the hot-spot locations were not influenced by the soil coverage, although showing a considerable and beneficial decrease in their amplitudes caused by the composite repair reinforcements.
Strategy Implementations—Can Organizations Attain Outstanding Performance?

Abstract Using the Northern Nevada plumbing industry as the sample, this article assesses and tries to validate the correlation between the challenges of effective leadership behavior and successful strategy implementation. The study's findings mostly agree with earlier research (Schaap, 2006) on the concept of strategy implementation. The present study reaffirms the role that strategic consensus plays in the strategy implementation process. It also reinforces findings by other researchers as well that frequent communication up and down the organizational structure enhances strategic consensus through the fostering of shared attitudes and values. In addition, it reaffirms the concept that senior-level leaders who have been trained in strategic planning and implementation are more likely to meet the performance targets than are those without training in the field. Based on the evidence presented, the study concludes that in order to achieve outstanding performance, strategy implementation plans must be cle.
