Electrothermal Design of a Discrete GaN-Based Converter for Integrated Modular Motor Drives

Integrated modular motor drives (IMMDs) have a compact and high fault-tolerant structure compared to their conventional counterparts. The most challenging issue in the implementation of these drives is the thermal management of the inverter modules due to the small space available for each module and its physical proximity to the machine windings with their high heat production. The electrothermal design of a discrete half-bridge inverter module for a radially stator-mounted (RSM) axial flux integrated drive is introduced in this article. The inverter modules are mounted on the stator, radially along the circumference. The converter is implemented using GaN technology, and the size is optimized. The structure of the presented integration topology from the case of the switches to the cooling ambient is optimized from the thermal point of view. The converter is modeled using steady-state and transient lumped parameter thermal networks to estimate the steady state and the instantaneous temperature of the switches. The converter parasitics are extracted using FEM simulations, and their influence on the switch loss and temperature is evaluated. The lumped parameter modeling is validated with computational fluid dynamics (CFD) simulations and experimental measurements.
Forms of phosphorus in composts and in compost-amended soils following incubation

Gagnon, B. , Demers, I. , Ziadi, N. , Chantigny, M. H. , Parent, L. -É. , Forge, T. A. , Larney, F. J. and Buckley, K. E. 2012. Forms of phosphorus in composts and in compost-amended soils following incubation. Can. J. Soil Sci. 92: 711-721. Information on the forms and bioavailability of P from composts applied to horticultural crops under organic production are required to promote soil quality and plant growth while protecting the environment. Seven composts were selected and characterized for their chemical composition. The composts were mostly mature and the total P contained 73 to 96% as inorganic P (Pi), although the total P concentration and P fractions varied amongst the materials selected for this study. These composts along with an inorganic P (KH2PO4) alone were added to three soils with contrasting chemical properties at a rate equivalent to 65 kg P ha-1 and incubated in the dark at 25°C. An unfertilized control was included to estimate soil P contribution. The amount and relative solubility of P from these compost-soil mixtures were evaluated by a modified Hedley fractionation after 2 and 16 wk of incubation. Results indicated that P added with composts was preferentially found in the Pi portion of soil labile pools after 2 and 16 wk. Except for the dairy cattle manure compost, all composts resulted in the same amounts of labile P (51-58%) and total Pi (61-98%) in soils, which were significantly lower than the labile P (82%) and close to the total Pi (108%) from inorganic KH2PO4 alone. Unlike the other composts, the potato residue compost produced a significant increase in the organic P fraction (Po) extractable with NaHCO3. This study indicated that Pi was the most important form of P in these composts and in the compost-amended soils. Nevertheless, it remains difficult to predict the availability of compost P following its application to soil.
Application of sprinkler cooling within the bunch zone during ripening of Cabernet Sauvignon berries to reduce the impact of high temperature

Background and Aim High temperature stress has been linked to detrimental effects on berry composition during ripening. This study aimed to assess the impact of an evaporative cooling system located inside the grapevine canopy to mitigate extreme temperature effects on grape berry composition during ripening. Methods and Results During three seasons (2012 to 2015), an intra-canopy sprinkler system at the bunch zone was tested on Cabernet Sauvignon vines. The system cyclically sprayed (20 s/10 min) for an air temperature above 38°C, cooling the air inside the canopy by 3 to 5°C. This is in agreement with an air cooling simulation model. The relative humidity in the canopy also increased in the sprinkler-cooled canopy. No differences were detected in TSS, although sugar per berry was significantly higher in treated vines because of increased berry mass. There was a tendency for higher anthocyanins and phenolic substances per berry in cooled berries measured from two seasons and higher concentration of anthocyanins in wine from cooled fruit measured only in one season. We define indices that can be used to assess the efficiency of sprinkler cooling and to demonstrate the high efficiency of intra-canopy sprinklers compared to other systems. Conclusion Despite cooling operating only over a small duration of the ripening period, the increased berry mass indicates that high temperature, even for a short period, has a profound effect on berry growth. Other berry compositional properties and wine, however, were not impacted. Significance of Study This research demonstrates the potential of an efficient intra-canopy sprinkler system to reduce heat stress during ripening.
500–2000-MHz Airborne Brightness Temperature Measurements Over the East Antarctic Plateau

Measurements of the 500–2000-MHz brightness temperature spectra of Antarctica acquired under the Ice Sheet and Sea Ice Ultrawideband Microwave Airborne eXperiment (ISSIUMAX) are reported. These data sets support the remote sensing of ice sheet properties, in particular information on the temperature profile within the ice sheet. The Ultrawideband Software-Defined Microwave Radiometer (UWBRAD) was installed on a Twin Otter aircraft, and measurements were collected on coastal areas and the interior of East Antarctica in November and December 2018. UWBRAD 500–2000-MHz brightness temperature measurements along a 1000-km path over the ice sheet are compared in this letter to forward model simulations for these locations and confirm the expected sensitivities to ice sheet parameters.
Oxidative stability of the salad dressing enriched by microencapsulated phenolic extracts from cold-pressed grape and pomegranate seed oil by-products evaluated using OXITEST

Salad dressings type emulsions have more than 30% vegetable oil with a high level of unsaturated fatty acids. Oxidation is the main deterioration reaction determining the shelf life of the emulsions containing a high level of unsaturated fatty acid. The shelf life of the salad dressing type emulsions ranges from 6 to 12 months at room temperature and can be increased by retarding of oxidation. The primary method of the retarding of oxidation and increasing shelf life is the addition of antioxidants. However, the majority of antioxidant substances currently used are synthetic materials having harmful potentials to human health. For this reason, in recent years, consumer preference has been shifted to natural sources of antioxidants instead of synthetic ones (Ghorbani Gorji et al., 2016).
“From a chef’s perspective or what I can sell on the menu?” Exploring culinary professionals’ attitudes toward specialty beef production and barriers to adoption

ABSTRACT This research aims to understand the attitudes and values of culinary ‘innovators’ already working with ‘local’ or ‘grass-fed/finished’ beef. Semi-structured interviews were conducted with specialty chefs and butchers in the Rocky Mountain Region based on the hypothesis that they operate as opinion leaders and understand that the benefits of, and barriers to, implementation of their current meat program is crucial for successfully introducing new products, such as Rocky Mountain Legume-Finished beef. Interviews revealed that professionals struggle with being ‘conscientious’ and ‘sustainable’ while still providing a consistent product for their customers. Although a few chefs spoke of setting ‘hard limits’ and ‘high standards’ for products, this did not emerge as a financial reality for other chefs or customers. In order for alternative sources of beef to be truly viable, beef production must address both environmental and economic concerns, while providing a consistent product in terms of taste and quality. Understanding the concerns of culinary professionals allows alternative ranching and agricultural production methods to be tailored as a viable for beef producers.

Simulation-aided development of automated solar shading control strategies using performance mapping and statistical classification

This paper presents a structured, generically applicable, method for using building performance simulation to aid the development of comfort-driven solar shading controls by mapping predicted occupant comfort conditions to sensor measurements. The method uses confusion matrices as a statistical classification approach to facilitate (i) selection of sensor deployment strategies that offer beneficial trade-offs considering multiple performance aspects and (ii) identification of control algorithms that optimise comfort conditions using non-ideal sensors. The support method requires relatively little effort from a developer, only a small number of simulations and fits well within the current practice of shading control development. The method is tested using a sun-tracking control strategy for indoor roller blinds as a case study, which demonstrates that the method can identify high-performance solutions. Finally, generally applicable features of the method are extrapolated from the case study, and alternative applications and the method’s limitations are discussed.

Use of early nasal continuous positive airway pressure in preterm neonates with hyaline membrane disease (neonatal respiratory distress syndrome)

Respiratory distress syndrome (RDS) is the commonest cause of respiratory distress in preterm infants. Deficiency of pulmonary surfactant is one of the most important factor contributing to the development of RDS. In immature lungs, the elevated surface tension resulting from surfactant deficiency leads to alveolar collapse at the end of expiration, atelectasis, uneven inflation and regional alveolar over distension. If untreated, results in epithelial injury and pulmonary edema which further interfere with surfactant function, producing the clinical picture of RDS.
Effect of Heavy metals on Growth and PGPR activity of Pseudomonads

MIC of copper, chromium, nickel, cadmium against P. putida strains were 195.45±28.76, 82.72±12.97, 164.54±30.08 and 138.63±33.42 µg/mL. Similarly, MIC of copper, chromium, nickel and cadmium against P. cepacia strains were 188.84±27.1, 85.38±14.26, 169.61±28.16 and 137.69±30.00 µg/mL. MIC of copper, chromium, nickel, cadmium against P. fluorescens strains were 192.97±28.1, 82.43±13.03, 150.27±37.54 and 144.59±28.92 µg/mL. Present study showed that heavy metals reduced growth as well as Plant growth-promoting rhizobacteria (PGPR) activity of previously characterized Pseudomonas strains.
A Synoptic Scale Perspective on Greenland Ice Core δ18O Variability and Related Teleconnection Patterns

The variability of stable oxygen isotope ratios (δ18O) from Greenland ice cores is commonly linked to changes in local climate and associated teleconnection patterns. In this respect, in this study we investigate ice core δ18O variability from a synoptic scale perspective to assess the potential of such records as proxies for extreme climate variability and associated weather patterns. We show that positive (negative) δ18O anomalies in three southern and central Greenland ice cores are associated with relatively high (low) Rossby Wave Breaking (RWB) activity in the North Atlantic region. Both cyclonic and anticyclonic RWB patterns associated with high δ18O show filaments of strong moisture transport from the Atlantic Ocean towards Greenland. During such events, warm and wet conditions are recorded over southern, western and central part of Greenland. In the same time the cyclonic and anticyclonic RWB patterns show enhanced southward advection of cold polar air masses on their eastern side, leading to extreme cold conditions over Europe. The association between high δ18O winters in Greenland ice cores and extremely cold winters over Europe is partly explained by the modulation of the RWB frequency by the tropical Atlantic sea surface temperature forcing, as shown in recent modeling studies. We argue that δ18O from Greenland ice cores can be used as a proxy for RWB activity in the Atlantic European region and associated extreme weather and climate anomalies.
Extracorporeal Shockwave Therapy With a Modified Technique on Tendon and Ligament for Knee Osteoarthritis

Supplemental digital content is available in the text. Background There have been no definitive guidelines on the treatment method and specific points in the body. Purpose The aim of the study was to investigate the effects of extracorporeal shockwave therapy on treating the main tendons and ligaments of knee osteoarthritis. Method A total of 36 patients with knee osteoarthritis were enrolled in trial and organized into two groups: 3-wk extracorporeal shockwave therapy for the intervention group and 3-wk sham extracorporeal shockwave therapy for control group. Both groups received the same physical therapies: (1) transcutaneous electrical nerve stimulation, (2) magnetic field treatment, and (3) quadricep muscle strength training. Evaluation was performed before the start of treatment, at third week after the start of treatment, and 1 wk after the end of treatment. The study used randomized controlled trials (level of evidence, 1). Result Eextracorporeal shockwave therapy group had significant improvement in WOMAC pain score, physical function, and total score (mean difference = −2.8, P < 0.001; −5.1, P = 0.02; −8.3, P = 0.004, respectively), Visual Analog Scale score (mean difference = −2.3, P < 0.001), and the distance of 6-min walk test (mean difference = 28.7, P = 0.01) in the 1 wk after the end of treatment. Statistical significance in WOMAC pain, physical function, and total scores (mean difference = −3.0, P = 0.001; −5.6, P = 0.02; −9.3, P = 0.004, respectively) and Visual Analog Scale score (mean difference = −1.2, P = 0.027) was observed between the extracorporeal shockwave therapy group and control group. Conclusions Extracorporeal shockwave therapy for the tendons and ligaments has clinical benefits for pain and physical function improvement in knee osteoarthritis. In addition, improvement in physical performance was observed in the short-term follow-up.
A Wideband Switched-Beam Antenna Array Fed by Compact Single-Layer Butler Matrix

This communication describes a wideband switched-beam antenna fed by a compact single-layer beamforming network. First, a novel hybrid coupler structure that can provide an arbitrary phase difference over a bandwidth larger than 58% is proposed with the theoretical analysis. Based on this compact coupler configuration, a wideband $4 \times 4$ Butler matrix is devised with the need for standalone phase shifters and crossovers eliminated. The proposed Butler matrix achieves the widest bandwidth among the single-layer structures up to present. Consequently, a wideband switched-beam antenna array is realized by utilizing the log-periodic endfire antenna elements with bowtie dipoles on the Butler matrix. For validation, a broadband switched-beam antenna array is designed, fabricated, and measured. A stable beamforming performance is ascertained with a gain variation smaller than ±1.66 dB over a bandwidth from 1.98 to 3.14 GHz.
Synthesis of Nano-Crystalline Zr0.8Sn0.2TiO4 Powder by Choline-Chloride-Malonate Deep Eutectic Solvents

Chloride-malonate deep eutectic solvent (Cm-DES) was applied to synthesize nano-crystalline Zr0.8Sn0. 2TiO4 ceramic powder by using Zr(CH3COO)4, SnCl2∙2H2O and Ti(OCH3CH3)4 as raw materials. The nano-crystalline Zr0.8Sn0. 2TiO4 powder was obtained at 450 °C, dramatically lower than that by solid state reaction. Meantime, the grain size of as-synthesized Zr0.8Sn0. 2TiO4 powder at 450 °C is 10.7 nm. In the synthesized process, Cm-DES, as a solvent and template, affects the synthesis process and the time required for synthesis is greatly reduced. These results show that the Cm-DES is suitable and prospective for the synthesis of nano-crystalline Zr0.8Sn0. 2TiO4 ceramic powder, which could contribute to reduce energy consumption and time cost.
Interest flooding attack mitigation in a vehicular named data network

Vehicular named data network (VNDN) is the next-generation network architecture for intelligent transportation system. Contrary to the conventional transmission control pro-tocol/internet protocol (TCP/IP) communication model, VNDN follows a data-centric approach where the user is interested in ‘WHAT’ instead of ‘WHERE’. Interest ﬂooding attack (IFA) is one of the prominent security concerns in VNDNs. In IFA, attackers request for non-existent content to exhaust network resources and cause Interest packet ﬂooding across the network. A novel attack mitigation scheme to counter IFA in VNDN has been proposed in this study. The proposed priority-based per-ﬂow Interest rate monitoring (PP-FIRM) scheme determines the suspicious ﬂow of malicious incoming Interest packets in attacked vehicles. A priority ﬂag is assigned to the incoming ﬂow of Interest packets that detects the occurrence of an attack. The priority of incoming Interest packet ﬂow is calculated using a collaborative or neighbour-assisted approach. A comparison with another attack mitigation scheme validates that the proposed scheme performs better in terms of an improved cache hit ratio and Interest satisfaction ratio during the attack window. Besides this, pending Interest table utilisation, packet collisions rate, Interest packets retransmission count, end-to-end delay, and the ratio of timed out Interest packets have also been reduced. Furthermore, the scalability of the proposed research strategy is also evaluated by changing the density of attackers
Racial Differences in the Effect of APOE-ε4 Genotypes on Trail Making Test Part B in Alzheimer’s disease

The trail making test part B (TMT-B) evaluates "executive" functions, memory, and sensorimotor functions. No previous studies were found to examine the longitudinal effect of apolipoprotein E epsilon 4 (APOE-ε4) genotypes on the TMT-B scores in Alzheimer’s disease (AD), and/or mild cognitive impairment (MCI) participants. This study used data from the Alzheimer's Disease Neuroimaging Initiative (ADNI): 482 participants with AD, 503 with cognitive normal (CN), 1,293 with MCI at baseline and follow-up of four years. The multivariable linear mixed model was used to determine the longitudinal changes in the TMT-B scores. The individuals with 1 or 2 APOE-ε4 alleles revealed significantly higher TMT-B scores (poor cognitive function) compared with individuals without APOE-ε4 allele at baseline and four follow-up visits (all p values < 0.0001). Compared with Whites, non-Hispanic African American and Hispanic populations had higher TMT-B scores (p = 0.0007 and 0.0044, respectively). Furthermore, stratified by diagnosis, the African American CN group had the highest TMT-B scores (p < 0.0001) and the Hispanic AD group had higher TMT-B scores (p = 0.0123) compared with Whites, while both African American and Hispanic MCI groups had higher TMT-B scores compared with Whites (p = 0.162 and 0.0274, respectively). In addition, stratified by racial groups, the subjects with APOE-ε4-homozgous and APOE-ε4-heterozgous showed higher TMT-B scores compared with subjects who carry zero APOE-ε4 allele just in Whites (p = 0.0023 and 0.0003, respectively); whereas there was no difference among APOE-ε4 genotypes in AA and Hispanics. In conclusion, the APOE-ε4 allele was associated with increased TMT-B scores but such associations varied by racial groups.
