GROWTH OF ORNAMENTAL SUNFLOWERS IRRIGATED WITH TREATED WASTEWATER UNDER ORGANIC PRODUCTION 2 ABSTRACT The use of wastewater is a practice with great advantages, especially in the supply of nutrients, a factor that contributes to faster growth. The sunflower (Helianthus annuus L.) is an ornamental plant with decorative interest, for its stunning beauty. The objective of this research was to study the growth of sunflower genotypes for cutting irrigated with domestic wastewater and supply water. The experiment was conducted in a greenhouse belonging to the Universidade Federal de Campina Grande, PB, in randomized block in a 4 x 2 factorial design with 3 replications utilising 4 sunflower genotypes (EMBRAPA 122 V2000 – G1, Sol Noturno – G2, Sol Vermelho – G3 and Debilis Creme – G4) and 2 types of water (supply water – A1 and treated wastewater originating from domestic sewage – A2). The use of wastewater under organic production provided the best mean results of growth for the studied genotypes and among the ornamentals, the Sol Noturno highlighted, with the maximum growth, and the Debilis Creme, with the least growth. The Debilis Creme genotype was the one that produced more accumulation of biomass under supply water treatment and the Sol Noturno when the wastewater was used but these facts occurred because of the individual potencialities of each genotype.

Employing reduced surface field technique by a P‐type region in 4H‐SiC metal semiconductor field effect transistors for increasing breakdown voltage

In this paper, we employ the Reduced Surface Field technique in metal semiconductor field effect transistors (MESFETs) by a P‐type region above the active layer near gate (PR‐MESFET). Electric field distribution can be made more uniform by a new depletion region in the active layer of the proposed structure that is created by a P‐type region. ‏‏Therefore, the electric field peak at the gate edge decreases, and the breakdown voltage increases. On the basis of our simulation results, the breakdown voltage increases as compared with the conventional bulk 4H‐SiC MESFET (CB‐MESFET) and the spacer bulk 4H‐SiC MESFET (SB‐MESFET). Detailed numerical simulations demonstrate that for proposed structure due to decrease in parasitic gate‐to‐drain capacitor, maximum oscillation frequency increases with respect to SB‐MESFET. Our simulation results show that output current slightly decreases in comparison with CB‐MESFET. Copyright © 2012 John Wiley & Sons, Ltd.

A Co‐Operative Quality Management System for Small Companies

Small companies have limited management and financial resources and, although better quality assurance will in the longer term reduce manufacturing costs, many are intimidated by the set up and running costs of certification under an approved scheme such as BS 5750. The article describes the first year's operation of a pilot scheme intended to help small companies resolve these problems. Experienced quality managers, recruited by an academic institution and with the institution's backing, have acted as managers for a group of small companies on a shared cost basis. The experience gained from this scheme is discussed.
Experimental investigation and CFD simulation of heave damping effects due to circular plates attached to spar hull

ABSTRACT Damping elements are used in ships and offshore structures as response reduction devices for maintaining the motion response within acceptable limits. The design of these elements relies on a combination of empirical approach and past experience. In this paper, an investigation of the wave excitation and hydrodynamic reaction forces acting on floating structures with and without damping elements is presented taking spar platform as the candidate structure. Understanding the flow pattern and vortex structure around these circular heave damping plates helps correlate the energy dissipation and damping. In the present study, measurement of hydrodynamic damping and inertia forces and response were carried out to establish the relationship between wave frequency and damping ratio. Flow pattern around the damping elements has been simulated using computational fluid dynamics (CFD) approach. Furthermore, flow visualisation and velocity measurement using particle image velocimetry (PIV) technique has been carried out in a wave flume for comparison and evaluation of the CFD approach. It was observed that the damping varies with wave period in a nonlinear fashion and it varies linearly with wave height. It was also observed that increase in added mass combined with viscous damping is a key factor for the effectiveness of heave plates in reducing motion response of spar platforms. Of the various configurations tested, the one with spar with double heave plate at the keel has higher damping and superior motion response compared to other configurations. The velocity pattern and vortex formation around the circular plates obtained through PIV study and CFD simulation showed good agreement.
Teacher narratives and understandings of (de)humanising pedagogy

A pre-requisite to teaching and learning for humanisation, is the acknowledgement of our situated selves. Situated selves are positioned in our previous, current, and future experiences. The words we use refer to realities and views of the world (Roux and Becker 2016). For Freire (1993, 68) “to speak a true word is to transform the world”. Education plays a crucial role in transforming people’s worlds, their mindsets, and social relations, that is, in how we name and rename our world. Teachers, therefore, are key mediators of transformative change as agents of social justice, and in the facilitation of learning as transformative specialists (Giroux 1983). Education is therefore a space that would reap the benefits of humanisation. The case study draws on teacher narratives and interviews to explore how teachers understand and reflect on a humanising pedagogy. I conclude that drawing on a humanising pedagogy is a priority for student accomplishment and significant for academic and social resilience.
Application of Random Vibration Techniques to Resonant Column Testing

A 152.4 mm (6 in) diameter resonant column device was modified to enable the direct measurement of torsional acceleration transfer functions of samples subjected to random excitation in the small-strain regime. Samples were tested over a wide range of confining pressures. By measuring the rotational acceleration of the end platens, the need to estimate the applied torque using a torque-current calibration factor for data reduction was eliminated, and issues such as back-emf, base fixity and eddy currents were bypassed. Preliminary calibration results illustrate that the first four peak frequencies and amplitudes can be readily employed for a calibration of modulus and damping characteristics over a wide frequency band, utilizing the continuous nature of the system rather than only the fundamental frequency of the specimen configuration.
Small-signal analysis of a single-stage bridgeless boost half-bridge AC/DC converter with bidirectional switch

A small-signal analysis of a single-stage bridgeless boost half-bridge alternating current/direct current (AC/DC) Converter with bidirectional switches is performed using circuit averaging method. The comprehensive approach to develop the small signal model from the steady state analysis is discussed. The small-signal model is then simulated with MATLAB Simulink. The small-signal model is verified through the comparison of the bode-plot obtained from MATLAB Simulink and the simulated large signal model in piecewise linear electrical circuit simulation (PLECS). The mathematical model obtain from the small-signal analysis is then used to determine the proportional gain K_p and integral gain K_i. In addition, the switch large-signal model is developed by considering the current and voltage waveforms during load transients and steady-state conditions.
Combination voltage-controlled and current-controlled PWM inverters for UPS parallel operation

In this paper, a scheme of combination of voltage-controlled and current-controlled PWM inverters for parallel operation of a single-phase uninterruptible power supply (UPS) is proposed. The voltage-controlled PWM inverter (VCPI) unit as a master is developed to keep a constant sinusoidal wave output voltage. The current-controlled PWM inverter (CCPI) units are operated as slave controlled to track the distributive current. The power distribution center (PDC) performs the function of distributing the output current of each active unit. In this proposed scheme of parallel operation, each of the units can be designed as nearly independent, and the CCPI units do not need a PLL circuit for synchronization. As a result, the parallel operation of UPS is easy to implement and to expand system capacity. For the purpose of illustration, the system, including three single-phase units which operate in parallel, is analyzed and experimental results are given. >
A fast technique for analysis of waveguides

The authors present a new technique for fast calculation of dispersion characteristics in inhomogeneously loaded waveguides. The method calculates an approximate value of propagation constant at a desired frequency based on more accurate computations of the field distribution and propagation constant at a few selected frequency points. Numerical tests show that the relative error in propagation constant below 0.05% can easily be obtained throughout a very wide frequency band for a dominant mode using accurate data calculated at as few as four frequency points.
Dispersion and attenuation characteristics of asymmetric multiconductor lines in suspended substrate structure using full‐wave modal analysis

The dispersion characteristics of asymmetric multiconductor lines in shielded suspended substrate (SSS) are evaluated using hybrid‐mode formulation. The numerical procedure, based on full‐wave modal analysis, is formulated to compute all the frequency‐dependent normal‐mode parameters for asymmetric multiconductor lines in a suspended substrate structure. The numerical results include the propagation constants, modal characteristic impedances, and attenuation constant. The perturbation formula has been used for the calculation of conductor and dielectric losses in the suspended substrate structure. Conductor loss is computed for the finite thickness using the perturbation theory and a comparison plot is provided to validate results. Dispersion characteristic of asymmetric three and four coupled microstrip lines in SSS are presented first time in this paper. © 2006 Wiley Periodicals, Inc.

A fundamental approach to transformer thermal modeling. I. Theory and equivalent circuit

A simple equivalent circuit to represent the thermal heat flow equations for power transformers is presented. Key features are the use of a current source analogy to represent heat input due to losses, and a nonlinear resistor analogy to represent the effect of air or oil cooling convection currents. The effect was first quantified in 1817. It is shown that the idea of "exponential response" is not the best way to think of the dynamics of the situation. It is also shown that one can consider ambient temperature to be a variable input to the system, and that it is properly represented as an ideal voltage source.
I-M-150847, a novel GLP-1 and GIP receptor dual agonist, improves glycemic control and reduces obesity in the rodent model of type 2 diabetes and obesity

We report the discovery of a novel unimolecular glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor dual agonist that exhibits potent glycemic control and weight loss in diet-induced obese mice. The dual agonism of GLP-1 and GIP receptor was achieved by replacing the tryptophan cage of exendin-4 with the C-terminal undecapeptide sequence of oxyntomodulin along with a single amino acid substitution from histidine to tyrosine at the amino terminus of the peptide. The structural modification places lysine 30 of the novel incretin agonist in frame with the corresponding lysine residue in the native GIP sequence. The novel incretin receptor dual agonist, named I-M-150847, induces rapid redistribution of GLP-1R at the plasma membrane following activation ensuring the maintenance of the receptor in a sensitized state. I-M-150847 promotes glucose-stimulated insulin exocytosis in cultured pancreatic beta cells and augments insulin-stimulated glucose uptake in mouse adipocytes. Chronic administration of I-M-150847 enhances insulin sensitivity, improves glycemic control, and achieves significant weight loss relative to the control or exendin-4-treated DIO-mice demonstrating the therapeutic efficacy of dual agonist in ameliorating type 2 Diabetes and Obesity. Significance statement. Replacement of the Trp-cage with the C-terminal oxyntomodulin undecapeptide along with the tyrosine substitution at the amino terminus converts the selective GLP-1R agonist exendin-4 to a novel GLP-1R and GIPR dual agonist I-M-150847. The GLP-1R and GIPR dual agonist I-M-150847 induces the expeditious redistribution of GLP-1R at the plasma membrane following initial activation thereby maintaining the receptor in a sensitized state. The incretin receptor dual agonist I-M-150847 enhances insulin sensitivity and delivers superior glycemic control and weight loss compared to exendin-4 in the rodent model of diabetes and obesity.

Planning and house building: A step change from the bottom up?

Current reforms of the British planning system are designed to address a range of perceived weaknesses in the way new housing, and the planning service more generally, are delivered. This paper draws on the findings of 11 local case studies to demonstrate how a range of local practices and initiatives – guiding new housing development – are addressing the need for greater speed and efficiency, the lack of inclusive planning and decision making, the failure to integrate policy areas, the lack of certainty and transparency in policy and its implementation, and finally, the accusation that planning is no longer a positive force in shaping the built environment. The aim is to highlight how some authorities, at least, have already embarked on a step change, and to argue that these local lessons should be built on during current attempts to reinvigorate the planning system.
A nonlinear lumped network model of semiconductor devices with consideration of recombination kinetics

A nonlinear lumped network model of semiconductor devices with consideration of recombination kinetics is developed. A distributed system, based on a set of recombination kinetic equations for the multiple energy level centers, in addition to continuity, current flow relationships, and Poisson's equation, is shown to be approximated by a lumped RC network. As an example of application, the forward characteristics of a gold-doped silicon diode are calculated. The calculated results are found to be in good agreement with the experimental results within the range where the recombination current through gold centers is dominant.
Statistical analysis on stimulated Raman crosstalk in dispersion-managed fiber links

Power impairments due to stimulated Raman scattering (SRS) in dispersion-managed (DM) fiber links are evaluated theoretically. We extend previous work on the statistical analysis of SRS crosstalk to the case of multiple fiber segments. Closed-form formulas are derived, and the applicable range is presented by comparison with simulation results. The SRS crosstalk in DM fiber links is evaluated using derived formulas, and the preferable configuration of DM fiber links for suppressing SRS crosstalk is discussed. We also evaluate the exact power penalty induced by the SRS crosstalk in consideration of the log-normal waveform distribution due to SRS and non-Gaussian noise and clarify the system bounds in some typical DM fiber links. The developed approach provides a design rule for DM fiber links from the viewpoint of SRS crosstalk suppression.

Late Cretaceous granitoids of the Sikhote–Alin orogenic belt, southeastern Russia: implications for the Mesozoic geodynamic history of the eastern Asian continental margin

We present new U–Pb age data for granitoids in the Central Sikhote–Alin orogenic belt in SE Russia, which refute the established opinion about the absence of the Late Cretaceous magmatism at the eastern margin of the Palaeo-Asian continent. It was previously thought that a period of magmatic quiescence occurred from 88 to 50 Ma, related to subduction of the Palaeo-Pacific plate under the eastern margin of the Palaeo-Asian continent, although this is inconsistent with evidence from the Sikhote–Alin, Sakhalin and Japan regions. Three suites of plutonic rocks with different ages were identified in this study. The first suite has ages of 105–92 Ma and formed in a syn-orogenic setting. The second (86–83 Ma) and third (c. 73 Ma) suites formed during the post-orogenic stage of the Sikhote–Alin orogenic belt. The second and third suites were coeval with Late Cretaceous granitoids that formed in a supra-subduction continental arc known as the Eastern Sikhote–Alin volcanic–plutonic belt. However, the studied rocks are located far inland from the Eastern Sikhote–Alin volcanic–plutonic belt. The ages of the studied granitoids coincide with the timing of a change in the angle of convergence between the Palaeo-Pacific plate and eastern margin of the Palaeo-Asian continent. This change in motion of the oceanic plate with respect to the continental plate was probably caused by a rupture in the subducted slab (i.e. a slab tear), followed by asthenospheric upwelling and partial melting of the overlying crust, which ultimately generated post-orogenic intrusive magmatism. Supplementary material: Laser ablation–inductively coupled plasma–mass spectrometry zircon U–Pb data of the Bikin–Bol.

Optimization of doping process on P-type wafer using spin-on technique

Measurement of junction depth (X/sub j/) value with respect to change in spin time, dopant volume and spin velocity during spin-on-doping process was obtained using groove and stain method. Theoretically, junction depth depends only on temperature and diffusion time. However, the result of this project indicate that spin time, spin velocity and dopant volume will also affect the value of junction depth.
Internet of things adoption, earnings management, and resource allocation efficiency

ABSTRACT This study aims at addressing the economic consequences of the adoption of the Internet of Things (IoT) in China. As the fundamental technology for the next-generation information technology, IoT is supposed to have the most profound and comprehensive influence on both business operation and accounting information environment. By using a difference-in-differences method, our findings focusing on earnings management activities in China-listed firms around the adoption of IoT confirm the conjecture that such technology effectively deters accrual-based and real earnings management. The results are also robust to dynamic analysis, instrumental variable approach, PSM analysis, placebo tests and other robustness tests. Furthermore, we also document that the reduction in real earnings management due to IoT adoption has positive implications on the capital market, financing and investment activities and long-term operational efficiency. Taken together, we reveal the promising prospects of IoT adoption on corporate accounting information and establish the association between information technology and efficiency of resource allocation.
Computation of magnetic field in DC brushless linear motors built with NdFeB magnets

A software package based on the finite-element technique has been used to compute three-dimensional magnetic fields and static forces in brushless DC linear motors. As the field flux-source, two different types of permanent magnets, one of them of the high-energy neodymium-iron-boron type, have been used in computer models. Motors with the same specifications as the computer models were built and experimental results obtained from them agreed well with the computed results. >
