Experimental verification of optimal flux weakening in surface PM machines using concentrated windings

Previous analytical work has shown that it is possible to design surface PM (SPM) machines using fractional-slot concentrated windings to achieve wide speed ranges of constant power operation by satisfying the optimal flux-weakening condition. This paper presents a 6 kW 36-slot/30-pole concentrated winding prototype SPM machine that has been designed using a closed-form analytical technique developed specifically for this class of machines. Experimental testing of this machine has been carried out to determine its performance capabilities, including flux-weakening operation. Detailed comparisons between analytical, finite element analysis (FEA), and experimental results are presented that confirm the ability of fractional-slot concentrated winding SPM machines to achieve their high-speed operating objectives. Important issues including the machine's back-emf voltage at top speed, eddy current losses in the magnets, and inverter performance are analyzed and discussed in detail.
Dexamethasone Attenuates the Expression of MMP-13 in Chondrocytes through MKP-1

Mitogen-activated protein kinase phosphatase-1 (MKP-1) is upregulated in inflammation and reduces the activity of proinflammatory mitogen-activated protein kinases (MAP kinases) by dephosphorylation. MAP kinases are intracellular signaling pathways that mediate the cellular effects of proinflammatory cytokines. In the present study, we investigated the effects of the glucocorticoid dexamethasone on the expression of catabolic enzymes in chondrocytes and tested the hypothesis that these effects are mediated through MKP-1. Dexamethasone was found to significantly attenuate the expression of matrix metalloproteinase (MMP)-13 in human OA chondrocytes as well as in chondrocytes from MKP-1 WT mice, but not in chondrocytes from MKP-1 KO mice. Dexamethasone also increased the expression of MKP-1 in murine and human OA chondrocytes. Furthermore, p38 MAP kinase inhibitors significantly attenuated MMP-13 expression in human OA chondrocytes, while JNK MAP kinase inhibitors had no effect. The results indicate that the effect of dexamethasone on MMP-13 expression in chondrocytes was mediated by an MKP-1 and p38 MAP kinase-dependent manner. These findings, together with previous results, support the concept of MKP-1 as a protective factor in articular chondrocytes in inflammatory conditions and as a potential drug target to treat OA.
The Relationship between Supervisor Ratio and Organizational Turnover: The Mediating and Moderating Effects of Engineers

Abstract The main purpose of this study was to examine the association between organizational supervisor ratio and engineer supervisor percentage with engineer turnover and total organizational turnover. Our study has new implications for the effects of supervisor ratio, which has not been specifically investigated in past engineering management research. Hierarchical multiple regression analysis was used on 85 organizational-level datasets from 17 large U.S. federal agencies. The findings suggest that engineer turnover is negatively related to supervisor ratio and positively related to engineer supervisor percentage. Mediation and moderation effects were observed. The study found partial mediating effects of engineer supervisor percentage in weakening the negative association between supervisor ratio and engineer turnover. Engineer turnover was also found to moderate the negative association between supervisor ratio and non-engineer turnover rate. This study further provides a theory-building framework for the role of organizational supervisor ratio in mitigating turnover risk for both engineers and all other knowledge workers in interdisciplinary work environments. Applying value congruence theory, engineering managers can use these findings to understand the role of supervisor ratio in organizational design and its impact on engineer turnover. We conclude with practical engineering management recommendations for engineer-manager training programs, engineer mentorship, organizational strategic communications, and the strategic deployment of engineers across the organization.
The stalemate: Motivational interviewing at a carceral junction

This study explores the use of motivational interviews to make non-compliant rejected migrants (‘rejecteers’) return. The study is based on qualitative data from field visits in accommodation centres for rejecteers (‘departure centres’) and from interviews with rejecteers and with the police interviewers conducting the interviews. A thematic analysis showed that these interviews differ from similar dialogue techniques by confronting the interviewees with their situation as seen by the state, in turn eliciting negotiations of belonging and borderwork in the form of repeated rejections. The motivational interviews fail to convince rejecteers that return is viable, especially because they reduce the complicated social situation of rejecteers to a need for responsibilisation. Rather than changing the spatial imaginaries of rejecteers, these motivational interviews block dialogue and engender incomprehension, demotivation and frustration on both sides of the table. In lieu of solving the problem of return, the main function of the motivational interviews is to be spectacles of enforcement that serve to individualise responsibility and to absolve the state of the responsibility for the social problems of ‘rejecteers’.
Exploring directed network connectivity in complex systems using large-scale augmented Granger causality (lsAGC)

Unveiling causal relationships among time-series in multivariate observational data is a challenging research topic. Such data may be represented by graphs, where nodes represent time-series, and edges directed causal influence scores between them. If the number of nodes exceeds the number of temporal observations, conventional methods, such as standard Granger causality, are of limited value, because estimating the free parameters of time-series predictors lead to under-determined problems. A typical example for this situation is functional Magnetic Resonance Imaging (fMRI), where the number of nodal observations is large, usually ranging from 102 to 105 time-series, while the number of temporal observations is low, usually less than 103. Hence, innovative approaches are required to address the challenges arising from such data sets. Recently, we have proposed the large-scale Augmented Granger Causality (lsAGC) algorithm, which is based on augmenting a dimensionalityreduced representation of the system’s state-space by supplementing data from the conditional source timeseries taken from the original input space. Here, we apply lsAGC on synthetic fMRI data with known ground truth and compare its performance to state-of-the-art methods leveraging the benefits of information-theoretic metrics. Our results suggest that the proposed lsAGC method significantly outperforms existing methods, both in diagnostic accuracy with Area Under the Receiver Operating Characteristic (AUROC = 0.894 vs. [0.727, 0.762] for competing methods, p < 10−9), and computation time (0.7 sec vs. [9.7, 4.8×103] sec for competing methods) benchmarks, demonstrating the potential of lsAGC for large-scale observations in neuroimaging studies of the human brain.
Development of a low-cost weather station and real-time monitoring for automated irrigation management

Irrigation is a practice that increases productivity and enables the expansion of agricultural borders. This practice should be well managed to ensure the efficient use of water by plants, and such management requires specialized labor, which increases operating costs. Therefore, the main objective of this study is the implementation of an automated irrigation system that considers factors ranging from water demand to the operation of the system. Because the daily water demand is determined by crop evapotranspiration, a low-cost weather station was developed to acquire data daily. Such data can be used to estimate the reference evapotranspiration (ET0) using the Penman-Monteith model of the Food and Agriculture Organization (FAO). Thus, by combining the amount of water required by a crop with the physical and hydraulic properties of the soil and the hydraulic properties of the irrigation system, it was possible to determine the daily frequency and amount of time required for the system to operate to meet the water requirements of the crop without undergoing stress from a deficit or an excess of water. The management/monitoring system was designed and implemented to allow the user to access data remotely through an online application. This application enables the real-time transmission of irrigation-related data, such as weather station data and system logs, obviating the need for the user to be present at the crop site. This allows the supervision of many areas simultaneously with low cost
Antitumor and antileishmanial activities of limonene-thiosemicarbazones bearing heterocycles nucleous

In the present study, we provided the synthesis of a series of R-(+)- and S-(-)-limonene-based thiosemicarbazones containing different pentacyclic heterocyclic nucleus moiety focused in the search of novel antitumor and antileishmanial agents. In the antitumor assay, the derivative imidazole of S-(-)-limonene 8 was the most active compound, especially for U-251, UACC-62 and K562 human tumor cell lines with GI50 ranging from 1.0 to <0.25 µg. mL-1. On the other hand, the imidazole-thiosemicarbazone of R-(+)-limonene 4 was the most promising derivative against the promastigote form of L. amazonensis (IC50=5.9µM). Meanwhile, thiosemicarbazones without limonene moiety (9-12) showed the lowest activities in the biological assays performed. The results demonstrated the influence of the lipophilic molecular character and stereochemistry of chiral monoterpene on the evaluated activities.
The impact of ‘seasonal urban event’ to the hosting city’s urban vitality: case study of Summer beach and Winter Wonderland in Nottingham, UK

Hosting seasonal urban events in open public spaces has a significant impact on urban vitality. By reviewing the categorisation of urban events, this paper explains the charactersitics of ‘Seasonal Urban Event’ through time, scale, location, format, content, function, and aim. It mainly focuses on leisure and entertainment events through two cases, Summer Beach and Winter Wonderland at Old Market Square in Nottingham, UK. The research explores ‘Seasonal Urban Event’ by literature review, open data, observation, and the survey data analysis of participants’ responses. The survey result indicates positive spatial and social engagement levels ranging from accessibility, legibility, permeability, flexibility to participation, satisfaction, and inclusivity. The potential benefits of social impact have been emphasised by participants’ responses to elevating civic pride and improving the level of social inclusion. It concludes that ‘Seasonal Urban Event’, as a useful supplement method, may enhance urban vitality in the hosting city
Low energy design of digital circuits

This thesis focuses on different aspects of ”Low Energy Design”. First, reversible logic, as it is the first attempt for low energy computing, is briefly dis- cussed. Then, we focus on dynamic energy saving in the combinational part of CMOS circuits. We propose a new method to reduce glitches based on dual threshold voltage technique. Simulation results report more than 16% average glitch reduction. We also show that combining dual-threshold to gate-sizingtechnique is very interesting for glitch filtering as it brings up to 27 % energy savings. In the third part of this dissertation, we have been interested in sub-threshold operation where the minimum energy can be achieved using a reduced supply voltage. Sub-threshold operation has been an efficient solution for energy-constrained applications with low speed requirements. However, it is very sensitive to process variability which can impact the robustness and effective performance of the circuit. We propose a model valid in sub and near threshold regions in order to correctly estimate the circuit performance in a variability aware analysis. We provide an analytical solution for the optimum supply voltage that minimizes the total energy per operation while considering variability effects. Spice simulations matches the analytical result to within 6%.
DENSE GAS PROPERTIES IN ARP 220

Studying dense gas is of fundamental importance for understanding star formation and galaxy evolution. We present data from the Atacama Large Millimeter/Submillimeter Array (ALMA) for the dense molecular gas tracers HNC (hydrogen isocyanide) with transition J = 2-1, CS (carbon monosulfide) with transition J = 4-3, and CO (carbon monoxide) with transition J = 6-5. We studied some properties of dense gases to find their effect on star formation in Arp 220 galaxy. We identify Arp 220 into two regions in which we reveal emission from every one of the three molecules, including the east and west nuclei. We calculate the ratios of LHNC/LCO, LCS/LCO, and LCS/LHNC at a sub-arcsecond scale. The ratios of LHNC / LCO and LCS / LCO represent fractions of the dense molecular gas. The values of these ratios are found equal to (0.31, 0.67) and (0.15, 0.31) in the west and east nuclei, respectively. We detect that these ratios are greater in the east nucleus than in the west nucleus. We also calculated the star formation efficiency (SFEdense), which is the rate of star formation per unit dense gas mass at a sub-arcsecond scale. We found that this galaxy has a long depletion time and low SFEdense compared to the global scale.

A CPW‐fed circular patch antenna inspired by reduced ground plane and CSRR slot for UWB applications with notch band

A coplanar waveguide (CPW) fed ultra‐wideband antenna is proposed for UWB applications. The proposed antenna consists of circular monopole with single complementary split ring resonator (CSRR) slot and reduced ground plane. The overall size of an antenna is 20 × 25 × 1.6 mm3. The prototype antenna is designed, fabricated and tested. It provides good return loss characteristics and radiation pattern. The measured −10 dB impedance bandwidths are 1.06 GHz (3.9–4.96 GHz) and 4.5 GHz (6.7–11.2 GHz) with resonance frequencies at 4.4 and 9 GHz, respectively. An appropriate dimension of CSRR slot has been etched on patch to notch 5–6 GHz band to avoid interference with WLAN and WiMAX devices which is one of the crucial issues to be solved in UWB antenna. Parametric studies on width of ground plane and dimension of CSRR slot are done to investigate the effect of various geometrical values on antenna characteristics. The simulated and measured results of the antenna are in close agreement with each other which will confirm the applicability of the proposed antenna. © 2017 Wiley Periodicals, Inc.

Lean Production: Denial, Confirmation or Extension of Sociotechnical Systems Design?

This paper makes a comparison between the basicelements of lean production and sociotechnical systemsdesign (STSD) and compares them both with thecharacteristics of the traditional Fordist system of mass production. It argues that lean productioncan hardly be considered as an alternative to massproduction, as its proponents suggest, but is on thecontrary extending the life of mass production methods. However, lean production does appear to containsome building blocks for the innovative productionsystems that are expected to prevail in the 21stcentury. STSD, which has always presented itself as an alternative and possible successor to Fordistmethods, will need to link its traditional concerns forquality of work and flexibility of work organizationswith the new issues of continuous improvement, learning,and innovation.
Forecasting of Road Traffic Flow Based on Harris Hawk Optimization and XGBoost

With the development of society and economy, people's living standards are improving day by day. The number of private cars is increasing, and the problem of urban traffic congestion is becoming more and more serious. Short-term traffic flow prediction is crucial to assist intelligent transportation system decision-making, solve congestion problems, and improve road capacity. In order to effectively improve the prediction accuracy and improve the generalization performance of the model, this paper combines extreme gradient boosting (XGBoost) and harris hawk optimization (HHO) to propose a multi-step prediction hybrid model. When building a hybrid model, the hyperparameter selection of the XGBoost model is converted into an optimization problem, and the optimization problem is solved through HHO. The solution to the final optimization problem is the optimal parameter combination of the XGBoost model. In order to verify the performance and competitiveness of the model, this study applies the proposed model to traffic flow prediction together with seven other representative models. The results show that the model has high accuracy and stability in practical applications.
Recent Strategies for the Immobilization of Therapeutic Enzymes

Therapeutic enzymes play important roles in modern medicine due to their high affinity and specificity. However, it is very expensive to use them in clinical medicine because of their low stability and bioavailability. To improve the stability and effectiveness of therapeutic enzymes, immobilization techniques have been employed to enhance the applications of therapeutic enzymes in the past few years. Reported immobilization techniques include entrapment, adsorption, and covalent attachment. In addition, protein engineering is often used to improve enzyme properties; however, all methods present certain advantages and limitations. For carrier-bound immobilization, the delivery and release of the immobilized enzyme depend on the properties of the carrier and enzyme. In this review, we summarize the advantages and challenges of the current strategies developed to deliver therapeutic enzymes and provide a future perspective on the immobilization technologies used for therapeutic enzyme delivery.
Savings and Losses of Scarce Virtual Water in the International Trade of Wheat, Maize, and Rice

The international cereal trade can mitigate global water stress by saving virtual scarce water (VSW). Based on bilateral trade data, this study assessed VSW savings and losses in the international trade of three major cereals (i.e., wheat, maize, and rice) from 2008 to 2017 by incorporating the water stress index (WSI) into a virtual water assessment. We found that the trade in wheat and maize saved a significant amount of VSW, while the rice trade led to increasingly severe losses of VSW. This study identified the top trades of VSW savings and losses for each cereal. Wheat and maize were primarily exported from the countries that are relatively abundant in water resources (e.g., United States, Brazil, Argentina, Russia) to water-scarce countries (e.g., Mexico and Egypt), whereas rice was exported mainly from India and Pakistan, two of the most water-stressed countries. We suggest that policy makers consider VSW savings and losses when making cereal trading decisions to alleviate global water stress.
Comparison Of Sharia Banking Performance Implementation Based On Maqashid Shariah Index In Sharia Banks In Indonesia And Malaysia

This study aims to analyze the performance of Islamic banking in Indonesia and Malaysia. At present, the measurement of the performance of the Islamic banking industry uses only the measurement of financial ratios (which are oriented towards shareholders). This measurement is not enough. Islamic banking needs a new paradigm in terms of measuring its performance of the which is not only limited to financial ratios. This study Applies approach the maqashid shariah index as a measurement of sharia banking performance. This type of research used in this study is comparative research. The object of this research is the Islamic banking industry, there are eight Islamic banks in Indonesia and nine Islamic banks in Malaysia that meet the criteria. The type of the data used is secondary the data in the form of financial reports / annual reports Obtained from the official website of each bank. By using the different test analysis method, the F count for the MSI variables with variances assumed aqual (assumed that both variants are equal) is 2002 with a probability of 0117. Because the probability of the data> 0.05, it can be concluded that there is no significant difference in the variance in the performance comparison of data based on the MSI of Islamic Banks of Indonesia and Islamic Banks of Malaysia.
Nutritive Value and Fermentation Characteristics of Tithonia diversifolia and Moringa oleifera Evaluated by Gas Production Technique in vitro

Paitan ( Tithonia diversifolia ) and kelor ( Moringa oleifera ) leaves contain high crude protein, which can increase the protein content of the feed. This study aims to determine the role of pain leaf ( Tithonia diversifolia ) and kelor ( Moringa oleifera ) as a concentrate in vitro. Another feed ingredient used is rice bran. A completely randomized design with five treatments and five replications was applied in this study. The treatments were A ( Tithonia diversifolia leaves without rice bran), B ( Tithonia diversifolia leaves 75% + rice bran 25%), C ( Tithonia diversifolia leaves 37.5% + Moringa oleifera leaves 37.5% + 25% rice bran), D ( Moringa oleifera leaves 75% + rice bran 25%) and E ( Moringa oleifera leaves without rice bran). Parameters observed were nutrient content, in vitro gas production and rumen fermentation products. The results showed that the crude protein content of treatments B, C and D was lower than A and E due to the use of rice bran which had a low crude protein content, but the addition of rice bran in the feed resulted in higher gas production (P<0.05). The combination of the use of rice bran and Moringa oleifera leaves (treatment D), resulted in the highest gas production up to 48 hours of incubation (P<0.05). The highest gas production from the fermentation of soluble (GPSF) and insoluble (GPNSF) fractions resulting from treatment D were 11.01 ml and 137.48 ml respectively. Anti-nutrients found in Tithonia diversifolia leaves make gas production lower than anti-nutrients found in Moringa oleifera leaves. 25% rice bran on feed could increase metabolizable energy (ME), organic matter digestibility (OMD), microbial protein (MP) and single-chain fatty acid (SCFA) production. It can be concluded that the use of 25% rice bran in feed containing Tithonia diversifolia and Moringa oleifera can reduce the anti-nutritional effect.
