The Effect of Adding Chitosan and Oxytetracycline to Wheat-Soybean Diet on The Productive Performance of Broiler Chickens

This experiment was conducted in the poultry farm of the Animal Production Department/College of Agriculture/Anbar University, for the period from 8/12/2019 until 23/3/2019 for (42 days). The experiment aims to compare the addition of two different levels of Chitosan and one level of antibiotic to the wheat-soybean diet and their effect on the productive performance of broiler chickens from the age of 7-42 days. The experimental treatments were T1: control (without any addition), T2: addition of 0.2 g Oxytetracycline/kg feed, T3: addition of 1 g Chitosan/kg feed and T4: addition of 2 g Chitosan/kg feed. The birds were randomly distributed to four treatments, with 3 replicates per treatment, and 12 birds for each replicate, where 144 chicks, 7 days old of Ross broiler chickens with an average weight of 168.7g were used in the experiment. The results showed that there were no significant differences in live body weight, weight increase and the relative growth rate of broiler, while significant differences occurred between treatments in the feed consumption rate during the first and fifth week and the duration from 7-21 days The T4 decreased significantly from T2 and T3, after which there was a significant decrease in the treatment of T3 from the T1 and T2 treatments in the fifth week. As for the feed conversion factor, there was no significant difference, as well as the percentage of mortality during the 7-42 days.
Heterosis and Genetic Diversity of Yield and Its Some Components in F1 of Sunflower Inbred Lines

Fall season 2020, six inbred lines of sunflower were crossed by half-diallel crosses to obtain 15 single hybrids. The genotypes (parents and first-generation hybrids -F1) were planted in randomized comlete block design (RCBD) with three replications in a field/Babylon Governorate during the spring season 2021. The study aimed to estimate Heterosis of the first generation hybrids from the mean of the parents for the traits; stem diameter, head diameter, number of seeds per head, weight of 100 seeds, seed yield and oil yield per plant. Furthermore, estimation of genetic distance among genotypes using cluster analysis. The results of the analysis of variance showed that there were significant differences at the probability level (0.01) for all the studied traits of the parents and the first generation hybrids. The two hybrids (I×Q) and (Q×C) were distinguished a high significant positive heterosis for most of the traits measured. The cluster analysis showed that the two genotypes that include hybrids (Q×C) and (Q×F) had the highest Euclidean distance (175.92 and 183.66) respectively. This indicated to high degree of genetic diversity between the two hybrids and the rest of the studied hybrids, which it positively reflected on the performance of the hybrids for the studied traits. The results of Principal Component Analysis (PCA) and Dendrogram showed that (Q) genotype was far from the rest of the genotypes and isolated to a single group, whereas the remaining genotypes separated into groups to two separed branches, especially the two genotypes (C( and )Q). The reason may be due to the distinguish genetic difference of these interested genotypes which have the ablility to transfer from parents to the its progenies, which resulted from a presence of the clear genetic distance between them, while, other genotypes lacks the of this genetic variation case.
An energy-economic analysis of real-world hybrid building energy systems

A coordinated operation of decentralised micro-scale hybrid energy systems within a locally managed network such as a district or neighbourhood will play a significant role in the sector-coupled energy grid of the future. A quantitative analysis of the effects of the primary energy factors, energy conversion efficiencies, load profiles, and control strategies on their energy-economic balance can aid in identifying important trends concerning their deployment within such a network. In this contribution, an analysis of the operational data from five energy laboratories in the trinational Upper-Rhine region is evaluated and a comparison to a conventional reference system is presented. Ten exemplary data-sets representing typical operation conditions for the laboratories in different seasons and the latest information on their national energy strategies are used to evaluate the primary energy consumption, CO2 emissions, and demand-related costs. Various conclusions on the ecologic and economic feasibility of hybrid building energy systems are drawn to provide a toe-hold to the engineering community in their planning and development.
Cargo load shift and its influence on tank vehicle dynamics under braking and turning

Dynamic behaviour of a partly filled tractor-tank-semitrailer vehicle is investigated under simultaneous application of cornering and braking manoeuvres. A three-dimensional quasi-static model of a partly-filled tank of circular cross-section is developed and integrated into a comprehensive three-dimensional vehicle model to study its dynamic performance as a function of steering and braking input, and the fill volume. The liquid load movement occurring in the roll and pitch planes of the tank under combined steering and braking is derived as a function of the longitudinal and lateral accelerations, and the corresponding load shift is expressed in terms of instantaneous c.g. coordinates and mass moments of inertia of the liquid bulk, assuming negligible influence of fundamental slosh frequency and viscous effects. The response characteristics of the partly-filled tank vehicle are evaluated in terms of load shift, forces and moments induced by the cargo movement, dynamic load transfer in the lateral and longitudinal directions, directional and roll response, and braking performance of the vehicle. The dynamic response characteristics of the partly filled tank vehicle are further compared with those of an equivalent rigid cargo vehicle to demonstrate the impact of the liquid load shift under combined turning and braking manoeuvres. The results of the comparative study reveal that a partly filled tank vehicle is more susceptible to rollover during a braking-in-a-turn manoeuvre.
Modeling Grain Rotational Disruption by Radiative Torques and Extinction of Active Galactic Nuclei

Extinction curves observed toward individual Active Galactic Nuclei (AGN) usually show a steep rise toward far-ultraviolet (FUV) wavelengths and can be described by the Small Magellanic Cloud (SMC)-like dust model. This feature suggests the dominance of small dust grains of size a ≤ 0.1 μm in the local environment of AGN, but the origin of such small grains is unclear. In this paper, we aim to explain this observed feature by applying the RAdiative Torque Disruption (RATD) to model the extinction of AGN radiation from FUV to mid-infrared (MIR) wavelengths. We find that in the intense radiation field of AGN, large composite grains of size a ≥ 0.1 μm are significantly disrupted to smaller sizes by RATD up to d RATD > 100 pc in the polar direction and d RATD ∼ 10 pc in the torus region. Consequently, optical–MIR extinction decreases, whereas FUV-near-ultraviolet extinction increases, producing a steep far-UV rise extinction curve. The resulting total-to-selective visual extinction ratio thus significantly drops to R V < 3.1 with decreasing distances to AGN center due to the enhancement of small grains. The dependence of R V with the efficiency of RATD will help us to study the dust properties in the AGN environment via photometric observations. In addition, we suggest that the combination of the strength between RATD and other dust destruction mechanisms that are responsible for destroying very small grains of a ≤ 0.05 μm is the key for explaining the dichotomy observed “SMC” and “gray” extinction curve toward many AGN.
APLICABILIDADE DAS POLÍTICAS PÚBLICAS EDUCACIONAIS PARA INCLUSÃO DOS DEFICIENTES FÍSICOS EM GUARAÍ/TO SOB A ÓTICA DO DESENVOLVIMENTO LOCAL

Os deficientes fí­sico-motores são representantes da heterogeneidade social e os dispositivos legais que convergem na Lei de Diretrizes e Bases da Educação Brasileira (Lei 9.394/1996), amparados pela Lei 10.098/2000 que estabelece normas gerais e critérios básicos à promoção da acessibilidade das pessoas portadoras de deficiência ou com mobilidade reduzida, tornam possí­vel a inclusão desse grupo nas atividades econômicas. Assim, este estudo analisa quais são e como têm sido aplicadas polí­ticas públicas educacionais para inclusão dos deficientes fí­sicos no municí­pio de Guaraí­, Estado de Tocantins, sob a ótica do desenvolvimento daquela localidade. Como metodologia foi empregada uma pesquisa social que utilizou questionários e entrevistas com pessoas deficientes fí­sico-motoras a fim de avaliar a influência das polí­ticas públicas educacionais no processo de inclusão social. Com base nos resultados encontrados, a maioria dos deficientes fí­sico-motores de Guaraí­ nunca ingressou no mercado de trabalho e sobrevive de doações, aposentaria ou pensão. Além disso, eles não completaram a escolaridade na educação básica e poucos representantes finalizaram o ensino superior. Concluiu-se que as polí­ticas públicas educacionais para inclusão social de deficientes fí­sicos apresentam falhas e necessitam de adequações, fato que impacta no processo de desenvolvimento de Guaraí­/TO.
N ov 2 02 1 Why is it so difficult to realize Dy

Rare-earth doped barium zirconate (BaZrO3) ceramics are of interest as proton-conducting and luminescent materials. Here, we report a study of dysprosium (Dy) and other relevant point defects in BaZrO3 using hybrid density-functional defect calculations. The tetravalent Dy 4+ is found to be structurally and electronically stable at the Zr lattice site (i.e., as Dy0Zr), but often energetically less favorable than the trivalent Dy (i.e., Dy− Zr ) in as-synthesized BaZrO3, due to the formation of low-energy, positively charged oxygen vacancies and the mixed-site occupancy of Dy in the host lattice. The Dy/Dy ratio can, in principle, be increased by preparing the material under highly oxidizing and Ba-rich conditions and co-doping with acceptor-like impurities; however, postsynthesis treatment may still be needed to realize a non-negligible Dy concentration. We also find that certain unoccupied Dy 4f states and the O 2p states are strongly hybridized, a feature not often seen in rare-earth-containing materials, and that the isolated DyZr defect might be the source of a broad blue emission in band-to-defect luminescence.
Three-Dimensional Seismic Response of a Full-Scale Light-Frame Wood Building: Numerical Study

The experimental seismic responses of a full-scale two-story light-frame wood townhouse building, designed to modern U.S. engineered seismic design requirements, were compared against the predictions of a new software package entitled seismic analysis package for woodframe structures (SAPWood) developed recently within the NEESWood Project. The main objective of this paper was to verify the accuracy of the predictions from the SAPWood model, which incorporates shear deformations of shear walls as well as cumulative floor displacements caused by the out-of-plane rotations of the floor and ceiling diaphragms. A comparison was conducted on interstory drifts and shear wall deformations for various structural configurations (construction phases) of the test building and excitation levels. Good agreement was found between the numerical predictions and test results for the four different construction phases. The SAPWood model was shown to be a promising numerical tool for predicting the seismic response of light.
Assessment of Awareness about Breast Cancer among Women Residing in Urban Poor Sector of Belagavi-A Cross Sectional Study

Breast cancer is the most prevalent cancer in the world, India accounting for largest estimated deaths. Women present with advanced stages at which little benefit is derived from therapy resulting in poor survival. Women from poor sectors are at more risk because of inadequate knowledge and health care approach. Increasing their awareness can help in early detection and alter their treatment seeking attitude thus improving the survival rates. In order to assess the same, a Cross Sectional Study was conducted in 2015 among 393 poor urban women between the ages of 18-45 years, residing in Khasbag, Belagavi. Awareness of breast cancer, risk factors showed that 11.2% had poor knowledge, 57.5% had fair knowledge and 31.3% had good knowledge. With respect to signs and symptoms of breast cancer 71% had good knowledge, 27.7% had fair knowledge while only 1.3% had poor knowledge. Majority of the women had good overall knowledge (60.1%) and attitude (91.6%) levels. Most of them (97.2%) showed positive attitude towards seeking treatment. Association between knowledge and attitude was statistically significant (p<0.05); the women with fair (32.8%) to good (58.8%) knowledge had good attitude.
Modeling Perfluorinated Polyether-Based MR Fluids

This study investigates the field-induced rheological characteristics of PFPE-based MR fluids. Four PFPE-based MR fluid samples were prepared, each with a different solid loading. All samples contain a single grade of carbonyl iron powder with an average particle diameter of 2 µm. The PFPE base fluid enhances sedimentation stability and its composition and qualities are introduced in the article. The magnetization characteristics of the iron powder and a fluid sample are measured. Its magnetic properties are compared to known models from the literature. The shear-yield stress in all fluid samples is investigated experimentally, as a function of solid loading and the magnetic flux density. The results are compared to established shear stress models for MR fluids. Model parameters are set to conform to the PFPE-based MR fluids. The PFPE-based MR fluids are shown to have a comparable shear-yield stress, when compared to commercially available MR fluids with a comparable particle loading and particle size. An application for the PFPE-based MR fluids is introduced. This application is an adaptive MR prosthetic knee, utilizing the fluid in shear mode.
Manufacturing flexibility improvement and resource-based view: cases of automotive firms

To deal with dynamic and uncertain business environments, agile manufacturing is of interest to academics and practitioners. However, in order to achieve agile manufacturing, one of its dimensions is of major importance ? manufacturing flexibility. Most firms acknowledge how flexibility can be improved but few can successfully implement it to its full potential. This paper investigates important issues associated with the degree of manufacturing flexibility performance and develops a comprehensive framework based on resource-based view (RBV) for successfully implementing flexibility. A case study methodology is used. It can extract more information about the experiences of companies in the planning, implementation and operations of manufacturing flexibility. The manufacturing flexibility issues in five automotive companies in Thailand were investigated and qualitatively analysed. The resources and capabilities contributing to successful manufacturing flexibility are derived. They consist of the extents of resource redundancy, the abilities of production planning and control, degree of buyer-supplier coordination, and effectiveness of technology and organisation support.
Conceptual Design and Aerodynamic Study of Joined-Wing Business Jet Aircraft

The concept of joined-wing aircraft with nonplanar wings as conceived and patented by Wolkovitch is attractive due to various advantages such as light weight, high stiffness, low induced drag, high trimmed CLmax, reduced wetted area and parasite drag and good stability and control, which have been supported by independent analyses, design studies and wind tunnel tests. With such foreseen advantages, the present work is carried out to design joined-wing business-jet aircraft and study and investigate its advantages and benefits as compared to the current available conventional business jet of similar size, passenger and payload capacity. In particular, the work searches for a conceptual design of joined-wing configured business-jet aircraft that possesses more superior characteristics and better aerodynamic performance in terms of increased lift and reduced drag, and lighter than the conventional business jet of similar size. Another significant objective of this work is to prove that the added rigidity possessed by the joined wing configuration can contribute to weight reduction.
Comparative Modal Analysis of Gasketed and Nongasketed Bolted Flanged Pipe Joints: FEA Approach

It is widely known that resonance can quickly lead to failure in vibrating bolted flanged pipe joints. Condition monitoring is performed time to time in some industries for smooth operation of a system, whereas mostly trial-and-error tests are performed to control vibration. During all this process, the inherent design problems are not considered. A bolted flange joint in piping system is not a simple problem, being the combination of flange, gasket, bolts, and washers. The success of a bolted flanged pipe joint is defined by the “static mode of load” in the joint. However, it has been recognized that a “dynamic mode of load” governs in a gasketed bolted flanged pipe joint, which leads to its failure due to flange rotation, providing flange yielding, fatigue of bolts, and gasket crushing. This paper presents results of detailed 3D finite element and mathematical modal analysis under bolt up to determine natural frequencies and mode shapes of gasketed flanged joints with and without raised face in comparison to the nongasketed flange joint.
Does the Internet Reduce Gender Gaps? The Case of Jordan

Abstract This article investigates the link between digital technologies and female labour outcomes in a country with one of the lowest female labour force participation (LFP) rates. It exploits the massive roll-out of mobile broadband technology in Jordan between 2010 and 2016 to identify the effect of internet adoption on LFP, internet job search, employment and unemployment. Using panel data at the individual level and an instrumental variable strategy, the article finds that internet adoption increases female LFP and that the effect is driven by women who were not married in 2010, who also experience declines in marriage and fertility rates in response to internet adoption. An increase in online job search explains some – but not all – of the total increase in female LFP. Only women who are older and have higher levels of education experience an increase in employment in response to gaining internet access. The internet reduces the prevalence of traditional social norms among married women, but this channel does not explain the increase in female LFP.
The SASS^{1} scattering coefficient σ ° algorithm

This paper describes the algorithms used to convert engineering unit data obtained from the Seasat-A satellite scatterometer (SASS) to radar scattering coefficients ( \sigma\deg ) and associated supporting parameters. A description is given of the instrument receiver and related processing used by the scatterometer to measure signal power backscattered from the earth's surface. The applicable radar equation used for determining \sigma\deg is derived. Sample results of SASS data processed through current algorithm development facility (ADF) \sigma\deg algorithms are presented which include \sigma\deg values for both water and land surfaces, \sigma\deg signatures for these two surface types are seen to have distinctly different characteristics. As expected, \sigma\deg values for water show strong dependence on both incidence angle and wind speed. For land, \sigma\deg values are relatively independent of incidence angle above 20\deg and have values in the range -14 dB. \sigma\deg measurements of the Amazon rain forest indicate the usefulness of this type of data as a stable calibration reference target. Using this Amazon data, relative biases between all four antennas and both polarizations are shown to be less than 0.4 dB.
Time-resolved Rotational Velocities in the Upper Atmosphere of WASP-33 b

While steady empirical progress has been made in understanding the structure and composition of hot-planet atmospheres, direct measurements of velocity signatures, including winds, rotation, and jets, have lagged behind. Quantifying atmospheric dynamics of hot planets is critical for a complete understanding of their atmospheres, and such measurements may even illuminate other planetary properties, such as magnetic field strengths. In this manuscript we present the first detection of the Balmer lines Hα and Hβ in the atmosphere of the ultra-hot Jupiter WASP-33 b. Using atmospheric models that include the effects of atmospheric dynamics, we show that the shape of the average Balmer line transmission spectrum is consistent with rotational velocities in the planet’s thermosphere of km s−1. We also measure a low-significance day- to nightside velocity shift of km s−1 in the transmission spectrum, which is naturally explained by a global wind across the planet’s terminator. In a separate analysis the time-resolved velocity centroids of individual transmission spectra show unambiguous evidence of rotation, with a best-fit velocity of km s−1, consistent with the value of v rot derived from the shape of the average Balmer line transmission spectrum. Our observations and analysis confirm the power of time-resolved transmission spectra with a high signal-to-noise ratio to measure the velocity structures in exoplanet atmospheres. The high rotational and wind velocities we measure highlight the need for more detailed 3D global climate simulations of the rarefied upper atmospheres of ultra-hot gas giants.
SCExAO/MEC and CHARIS Discovery of a Low-mass, 6 au Separation Companion to HIP 109427 Using Stochastic Speckle Discrimination and High-contrast Spectroscopy

We report the direct imaging discovery of a low-mass companion to the nearby accelerating A star, HIP 109427, with the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument coupled with the Microwave Kinetic Inductance Detector Exoplanet Camera (MEC) and CHARIS integral field spectrograph. CHARIS data reduced with reference star point spread function (PSF) subtraction yield 1.1–2.4 μm spectra. MEC reveals the companion in Y and J band at a comparable signal-to-noise ratio using stochastic speckle discrimination, with no PSF subtraction techniques. Combined with complementary follow-up L p photometry from Keck/NIRC2, the SCExAO data favors a spectral type, effective temperature, and luminosity of M4–M5.5, 3000–3200 K, and log10(L/L⊙)=−2.28−0.04+0.04 , respectively. Relative astrometry of HIP 109427 B from SCExAO/CHARIS and Keck/NIRC2, and complementary Gaia–Hipparcos absolute astrometry of the primary favor a semimajor axis of 6.55+3.0 −0.48 au, an eccentricity of 0.54−0.15+0.28 , an inclination of 66.7−14+8.5 degrees, and a dynamical mass of 0.280−0.059+0.18 M ⊙. This work shows the potential for extreme AO systems to utilize speckle statistics in addition to widely used postprocessing methods to directly image faint companions to nearby stars near the telescope diffraction limit.
