Analysis of End-Windings Influence on the Transient Voltage Distribution in Machine Stator Windings by a Three Phase Model

Transient voltage distribution due to steep-fronted surges must be taken into account during the machine's design as it can lead to main and turn insulation failure. In medium voltage machines, the end-windings region has a considerable percentage of the coil length and plays an important role during transient studies. This article has the purpose of verifying the influence of end-windings on the transient voltage distribution by using a three-phase simulation model in which transient magnetic fields and electric circuit elements are coupled. The transient simulation and the calculation of the electrical parameters used in the model are done employing the Finite Elements Method (FEM). To verify the influence on the results, simulations for different surge rise times are performed, considering and neglecting the end-windings model. As main results, the intercoil and interturn voltages are analyzed for all turns from the three phases of one winding group. The model is validated by measurement results. It is shown that the end-windings, indeed, affect the transient voltage distribution for both, interturn and intercoil voltages, regarding the rate of rising (slope), instant, and the amplitude of the peak voltages. Moreover, all three phases are affected by the end-windings, especially for the turn-to-turn voltages.
Airflow resistance in soybean

Airflow resistance in soybean Resistance of material to airflow is an important factor to consider in the design of a dryer or an aeration system. The airflow resistance of soybean was determined with the modified airflow resistance apparatus. It was found that pressure drop increased with increase in airflow rate, bulk density, bed depth and decreased with moisture content. Modified Shedd equation, Hukill and Ives equation and modified Ergun equation were examined for pressure drop prediction. Airflow resistance was accurately described by modified Shedd equation followed by Hukill and Ives equation and modified Ergun equation. The developed statistical model comprised of airflow rate, moisture content and bulk density could fit pressure drop data reasonably well.
MODELING OF TRANSPORT PHENOMENA IN TWO-PHASE FILM-FLOW SYSTEMS: APPLICATION TO MONOLITH REACTORS

Transport phenomena in two-phase systems represent the basis of many industrial processes. The hydrodynamic behavior and process kinetics are crucial, especially when reacting systems are considered. For the modeling of such systems, usually the rate-based approach is applied, because it can handle even very complex hydrodynamic conditions. However, this method requires several experimental parameters, e.g., mass transfer coefficients. For processes with less complex flow patterns, alternative, more rigorous modeling methods can be applied. For instance, the fluid dynamic approach describes the fluid phase behavior based on classical partial differential transport equations and considers the real geometry of column internals directly. This method does not need mass transfer coefficients. In this work, we apply both the rate-based and fluid dynamic approaches to a particular process, namely, the esterification of 1-octanol and hexanoic acid in a film-flow monolith reactor, and analyze their performance.

On the physical and chemical details of alumina atomic layer deposition: A combined experimental and numerical approach

Alumina thin film is typically studied as a model atomic layer deposition (ALD) process due to its high dielectric constant, high thermal stability, and good adhesion on various wafer surfaces. Despite extensive applications of alumina ALD in microelectronics industries, details on the physical and chemical processes are not yet well understood. ALD experiments are not able to shed adequate light on the detailed information regarding the transient ALD process. Most of current numerical approaches lack detailed surface reaction mechanisms, and their results are not well correlated with experimental observations. In this paper, the authors present a combined experimental and numerical study on the details of flow and surface reactions in alumina ALD using trimethylaluminum and water as precursors. Results obtained from experiments and simulations are compared and correlated. By experiments, growth rate on five samples under different deposition conditions is characterized. The deposition rate from numerical.

TOROIDAL COIL COUNTERCURRENT CHROMATOGRAPHY SEPARATION AND ANALYSIS OF STAPHYLOCOCCAL ENTEROTOXIN A (SEA) IN MILK

Countercurrent Chromatography (CCC) utilizes continuous partitioning of solute between two immiscible solvent phases without a solid support. The absence of solid support makes CCC a suitable method for food analysis because it permits analysis of crude and complex materials that are not amenable to conventional solid-supported chromatography. CCC was evaluated for its ability to separate Staphylococcal enterotoxin A (SEA), a common cause of food poisoning, from milk. Although many foods can be analyzed for SEA directly by Western blot analysis, milk samples generally require some purification because the high concentration of milk proteins distorts SDS-PAGE mobility. Milk samples containing SEA were separated by toroidal coil CCC and the fractions were analyzed by Western immunoblotting. Fractions containing SEA were pooled, concentrated by ultrafiltration, and rechecked by Western immunoblotting. Concentrating the fractions increased the sensitivity of Western immunoblotting by approximately an order of.

Simultaneous Densitometric Determination of 6-Gingerol, 8-Gingerol, 10-Gingerol, and 6-Shogaol in Some Commercial Gingers

Abstract A simple and rapid densitometric method has been developed for determination of 6-gingerol, 8-gingerol, 10-gingerol, and 6-shogaol in some commercial gingers. After extracting the samples four times with methanol, the solutions were spotted on precoated Lichrosphere Si 60F254 HPTLC plates, which were eluted with a mixture of toluene–ethyl acetate (3:1, v/v). Quantitative evaluation was performed by measuring the absorbance reflectance of the analyte spots at λ = 577 nm after being sprayed with anisaldehyde-H2SO4 reagent. The HPTLC-densitometric method is cheap, selective, precise, and accurate and can be used for routine analysis of gingers in the herbal drugs industry quality control laboratories.
Fabrication of diamond-like amorphous carbon cantilever resonators

Amorphous carbon (a-C) films were deposited by an off-plane double bend filtered cathodic vacuum arc technique fitted with a plasma immersion ion implantation system. High resolution XPS measurements showed these films have an sp3 content of about 60%. Laser-surface acoustic wave measurements have shown such films to have a Young’s modulus and density of 310GPa and 2.33g∕cm3. 1. 2μm thick a-C films were grown and subsequently patterned into 150μm×50μm cantilevers using standard photolithography. Residual stress measurements were obtained from the curvature of bend of the cantilever. An accurate knowledge of the microstructural properties will in turn give accurate modeling results. Simulation results showed that such free-standing cantilevers fabricated with amorphous carbon films have resonant frequency much higher than standard polysilicon cantilevers. As such, free-standing diamond-like amorphous carbon cantilevers had been fabricated. The resonant frequency of these cantilevers was measured by laser vi.
Coconut husk as a biosorbent for methylene blue removal and its kinetics study

Biosorption of methylene blue (MB) from aqueous solution was studied with respect to the point of zero charge of coconut husk, dye concentration, particle size, pH, temperature, as well as adsorbent and NaCl concentration using coconut husk biomass. Amongst Langmuir and Freundlich adsorption isotherms studied, Langmuir adsorption isotherm showed better agreement. Pseudo second order kinetics model was found to be more suitable for data presentation as compared to pseudo first order kinetics model. Also, involvement of diffusion process was studied using intraparticle diffusion, external mass transfer and Boyd kinetic model. Involvement of intraparticle diffusion model was found to be more relevant (prominent) as compared to external mass transfer (in) for methylene blue biosorption by the coconut husk. Moreover, thermodynamic properties of MB biosorption by coconut husk were studied. Desorption of methylene blue from biomass was studied with different desorbing agents, and the highest desorption achieved was as low as 7.18% with acetone, which indicate stable immobilization. Under the experimental conditions MB sorption was not significantly affected by pH, temperature and adsorbent concentration but low sorption was observed at higher NaCl concentrations.

Attempted co-crystallization of tolbutamide with p-phenylenediboronic acid and p-nitrophenol in EtOH afforded a modulated high Z′ crystal structure of the known form III of tolbutamide instead of the anticipated co-crystals. A novel form V of tolbutamide was crystallized when a trace of conc. HNO3 was added in MeOH solvent.
Experimental study of a mercury high‐pressure discharge in the course of its start‐up phase

This work deals with an experimental study of the start‐up phase of a mercury high‐pressure discharge. We demonstrate, by using electrical and spectroscopic measurements, that a steady‐state discharge can be said to be equivalent to a specific stage of the warm‐up phase if, for a given current, arc voltage together with several spectral line intensities are the same in both states. Subsequently, using these measurements we were able to: (i) determine the evolution of the electric field and the voltage drop at the electrodes in the course of a start‐up phase; and (ii) establish that the determination of the excitation temperature of Hg and Ar excited levels gives us a first indication concerning discharge thermalization and local thermodynamic equilibrium hypothesis limits.
A 0.44-μJ/dec, 39.9-μs/dec, Recurrent Attention In-Memory Processor for Keyword Spotting

This article presents a deep learning-based classifier IC for keyword spotting (KWS) in 65-nm CMOS designed using an algorithm-hardware co-design approach. First, a recurrent attention model (RAM) algorithm for the KWS task (the KeyRAM algorithm) is proposed. The KeyRAM algorithm enables accuracy versus energy scalability via a confidence-based computation (CC) scheme, leading to a <inline-formula> <tex-math notation="LaTeX">$2.5\times $ </tex-math></inline-formula> reduction in computational complexity compared to state-of-the-art (SOTA) neural networks, and is well-suited for in-memory computing (IMC) since the bulk (89%) of its computations are 4-b matrix-vector multiplies. The KeyRAM IC comprises a multi-bit multi-bank IMC architecture with a digital co-processor. A sparsity-aware summation scheme is proposed to alleviate the challenge faced by IMCs when summing sparse activations. The digital co-processor employs diagonal major weight storage to compute without any stalls. This combination of the IMC and digital processors enables a balanced tradeoff between energy efficiency and high accuracy computation. The resultant KWS IC achieves SOTA decision latency of 39.9 <inline-formula> <tex-math notation="LaTeX">$\mu \text{s}$ </tex-math></inline-formula> with a decision energy < 0.5 <inline-formula> <tex-math notation="LaTeX">$\mu \text{J}$ </tex-math></inline-formula>/dec which translates to more than 24<inline-formula> <tex-math notation="LaTeX">$\times $ </tex-math></inline-formula> savings in the energy-delay product (EDP) of decisions over existing KWS ICs.
Application of Transition State Theory in Model Development for Temperature Dependence of Respiration of Fresh Produce

Abstract A relationship between O 2 consumption rate of fresh produce and temperature is expressed on the basis of transition state theory. The temperature dependence of the O 2 consumption rates of shredded cabbage, shredded lettuce, blueberries and raspberries is theoreticaly described by the modified Eyring ’s equation. Values of Gibbs energy of activation and the total number of O 2 consumption sites in the horticultural commodities affect the O 2 consumption rates of the commodities. Changes in O 2 and CO 2 concentrations in low density polyehylene pouches with shredded cabbage and shredded lettuce over time were properly simulated by using the O 2 consumption rate equation derived from transition state theory, gas permeability coefficients of the pouch, respiratory quotient ( RQ) and mass balance equations for O 2 , CO 2 and N 2 gases in the pouch. Validity of the transition state theory, expressing the temperature dependence of the O 2 consumption rate, for design of modified atmosphere packaging (MAP) systems is demonstrated in the present study.
Expression Pattern of Sulf1 and Sulf2 in Chicken Tissues and Characterization of Their Expression During Different Periods in Skeletal Muscle Satellite Cells

19/August/2019 Approved: 08/May/2020 ABSTRACT Heparan sulfate proteoglycans (HSPGs) are present on the cell surface and in the extracellular matrix in all metazoans. HSPGs interact with growth factors and receptors through heparan sulfate (HS) chains. The sulfation pattern of heparan sulfate chains influences signaling events mediated by heparan sulfate proteoglycans located on the cell surface. SULF1 and SULF2 are two endo-sulfatases that can cleave specific 6-O-sulfate groups within the heparan chains. To determine their possible roles in tissues and satellite cells in vitro, their expression pattern was examined in tissues from 40-day-old chickens and in satellite cells from the breast muscles of 1-week-old and 2-week-old chickens using RT-PCR and immunocytochemistry analyses. The SULF1 and SULF2 transcripts were widely distributed in various tissues. Upon increasing culture times in chicken´s primary skeletal muscle satellite cells, SULF1 and SULF2 expression in 1-week-old chickens was significantly higher than in 2-week-old chickens, suggesting that sulfatases play a key role in satellite cell development. Therefore, our findings increase our knowledge of sulfatase expression diversity and provide a solid basis for further research concerning
Improved Coplanar Couplers Based WPT Systems for Adaptive Energy Harvesting on Power Towers

Wireless power transfer (WPT) technology is promising for energy harvesting and electronics powering on power towers. This article presents an improved coplanar couplers based WPT system for adaptive energy harvesting on the towers. Magnetic flux analyses of conventional coaxial coils indicate that the significance of the adaptive and extensible performance in this application. Improved coplanar couplers are further proposed to reduce magnetic flux interactions between the WPT and high-voltage components and promote the performances, which include discrete transmitter windings, vertical receiver coil, and high-permeability layers. Related parameters are determined based on a concluded flow from a sequence of simulations. Moreover, performances of the WPT and high-voltage systems under operating conditions are simulated. The design does not break the high-voltage characteristic and shows robust performances from comparisons. Experimental results prove the effectiveness of the design with a 22.53% efficiency and an 18.98 W output power. Such an adaptive insulator-independent energy supply solution can be extended to different high-voltage towers.
Variabilidade e correlação espacial de micronutrientes e matéria orgânica do solo com a produtividade da pimenta-do-reino

Studies on the spatial variation of soil properties associated with the response of crop yields may contribute to a rational application of inputs, enabling economic and environmental gains. The purpose of this work was to evaluate the variability and spatial correlations among soil Fe, Cu, Zn, Mn, and organic matter contents and yield of black pepper grown on a Yellow-Red Latosol. The study was carried out on a black pepper plantation under microsprinkler irrigation, in Sao Mateus, State of Espirito Santo, Brazil. The experimental area was 100 x 120 m (12.000 m2). Soil was collected from under the tree canopies in the 0-0.20 m layer, in a grid with minimum distances of 5 m, totaling 126 soil samples. The black pepper production was estimated by harvesting the three plants nearest to each sample point. All measurable semivariogram properties were satisfactorily described by spherical models with a moderate and strong spatial structure. There was a negative spatial correlation between soil Fe content and yield black pepper and positive spatial correlation among Zn, Mn and organic matter contents and black pepper yield.
A Compact Substrate Integrated Waveguide Notched-Septum Polarizer for 5G Mobile Devices

In this letter, a compact substrate-integrated waveguide (SIW) notched-septum polarizer is designed, manufactured, and tested. Metalized slots are used instead of vias in proximity to the notches to improve polarization purity. An impedance matching bandwidth of 7.9% at 29 GHz and transmission coefficient of better than <inline-formula><tex-math notation="LaTeX">$-$</tex-math></inline-formula>1.6 dB are demonstrated. The axial ratio is less than 3 dB over a bandwidth of 4.5% at 29 GHz (sufficient for 5G). An implementation of the polarizer in an array antenna was measured to validate its reliability in antenna applications. Given its performance and small form-factor (length of <inline-formula><tex-math notation="LaTeX">$\lambda _o$</tex-math></inline-formula>/7 at 29 GHz), the proposed polarizer may be a good option for SIW circularly polarized endfire antennas in 5G mobile devices.
The Relationship between Play Repertoire and Inhibitory Control in Preschool Children

Numerous studies argue that inhibitory control could be successfully enhanced in play activities during preschool age. Previous studies showed that fantasy significantly associated with inhibitory control and cognitive flexibility. It was also shown that inhibitory control is related to symbolic play (imagination of absent objects, attributing imaginary properties to objects, accepting the role). The primary aim of the current study was to investigate the association between children’s play repertoire and inhibitory control in preschool age. Two research questions were addressed in this study. First, we hypothesized that reducing play activity to one favourite play and character could be associated with poorer inhibitory control, probably due to decreasing variability of roles, actions, possible choices. Second, we hypothesized that play duration correlates with the level of children’s inhibitory control performance: the more time is devoted to role-play, the higher the level of inhibitory control would be. Participants were 228 children aged 6-7 years. Child’s play preferences and play duration were examined with a parental questionnaire. Results indicate that children who had a favourite play were significantly more impulsive while dealing with the tasks which required inhibitory control. A similar result was obtained in the analysis of how having a favourite character relates to the inhibition process: a group of children who had favourite characters showed significantly lower score of inhibition control than groups of children who had no favourite characters or had multiple ones. This study did not show any significant differentiation among groups of children with different play duration per day. These findings contribute in several ways to our understanding of the relevance of play in terms of inhibitory control development.
Networking and Sustainable Performance of Small and Medium Enterprises in South Africa

The main objective of this study was to investigate the impact of networking on the sustainable performance of small and medium enterprises (SMEs). A quantitative approach was used, and a self-administered questionnaire was employed during the data collection process. Correlation and regression analyses were performed to determine the relationship between networking and sustainable performance. The Cronbach’s alpha was used as a measure of reliability. The results of the study revealed that networking positively impacts on the sustainable performance of SMEs. Recommendations to improve the networking of SMEs are suggested. These recommendations offered meaningful insights into SME owners, government, nongovernment organisations and other organisations for the improvement of their businesses while providing room for future research studies.
