Leakage Current Suppression With Capacitor Voltage Control of Three-Level Flying Capacitor Grid-Connected Inverters

Leakage current issues are worthy of attention for nonisolated grid-connected systems. This article introduces the method of eliminating common-mode (CM) voltage and reducing the leakage current based on modulation, and analyzes the correlation between actual effects of the method and the flying capacitor (FC) voltage balance in three-phase three-level FC grid-connected inverter. The proposed carrier-based modulation can balance the FC voltage by changing the transmission sequences of pulses and theoretically achieve zero CM voltage. In order to deal with the low frequency fluctuation and bias voltage of FC caused by asymmetry of actual hardware, the control method is introduced, which controls FC voltage by changing the action times’ distribution of switches, while still eliminating the CM voltage. Simulation and experimental results are provided to validate that the proposed method can control FC voltage and achieve good performance in suppressions of CM voltage, leakage, current and CM electromagnetic interference noise.
Teachers’ concepts of good citizenship and associations with their teaching styles

ABSTRACT Teachers are key agents in the political socialisation of adolescents. Therefore, knowledge about teachers’ beliefs concerning citizenship is essential, as these beliefs likely relate to how educators socialise young people via preferred modes of teaching. Studying the link between teachers’ citizenship norms and associated teaching styles can inform us about how to improve citizenship education in schools. The authors use the 2016 International Civic and Citizenship Education Study data, relying on the unique Teacher Survey conducted in Flanders (n = 1983) using multilevel latent class analysis. They identify five profiles of teachers’ concepts of good citizenship. These profiles are further correlated with goals of citizenship education emphasised by teachers as well as the sources and activities used to teach civics in the classroom. The results suggest that teachers can be seen as instructional gatekeepers, with teachers supporting more engaged and all-around norms of citizenship more frequently implementing active teaching styles.
Uncomfortable and worthy: the role of students’ field trips to dark tourism sites in higher education

ABSTRACT This article studies the importance of the educational experience of students in dark tourism sites, with a particular focus on post-visit effects after their exposure to dark sites – inner-directed and behavioural activities. Previous studies on the topic are limited, controversial, and reveal that field trips as a compulsory activity do not necessarily induce post-visit effects, but at the same time can provoke greater interest in certain topics, such as research or repeated visits. The study continues the strand of research of post-visit effects after exposure to dark tourism sites of the specific segment – university undergraduates. The study is based on longitudinal data collected after field trips to dark tourism sites in Latvia (2014–2019). In total, 119 Latvian and exchange students participated in field trips during the Dark tourism study course. Students reported about the post-visit effects by using questionnaires based on dark tourism theoretical frameworks. The programme included such dark tourism sites as the KGB Museum, Ghetto Museum, and memorials. The results indicate that students appreciate the educational value of the dark tourism sites and better-designed sites induce more post-visit effects. However, educational gains must be strengthened by stimulating professional knowledge and the will to research independently.
An Aut-Ecological Study of Acinetobacter in Activated Sludge

Data are reported on the role of Acinetobacter in phosphate removal in activated sludge. The fluorescent antibody (FA) technique was applied in an autecological study of Acinetobacter in this habitat. Results indicated that Acinetobacter was present in numbers exceeding 106 organisms per cm3 throughout all zones of the activated sludge process, with higher numbers occurring in the aeration zone. It was also found that Acinetobacter numbers did not vary regardless of whether phosphate was removed or not. Combined electron microscopy and electron dispersive micro-analysis of X-rays (EDAX) furthermore indicated that bacteria from phosphate removing activated sludge plants contained phosphate granules, whereas those from non-removing plants or where removal had stopped, did not contain phosphate granules at all. Hence, it was concluded that no major population shifts of Acinetobacter occurred in activated sludge and that the process of phosphate accumulation is induced in Acinetobacter. However, Acinetobacter never occurred in numbers sufficiently large to account for phosphate removal to the extent sometimes observed in activated sludge.
Reliability analysis of discrete multi-state systems based on survival signature

System signature has been widely utilized to facilitate reliability assessment of coherent systems and networks consisting of a single type of components, which enables us to separate aspects of components’ failure time and system structure. Recently, survival signature fulfils the similar work, extended to the implementation of systems with multiple types of components. However, when the system has several states, the relevant work is limited to complete the reliability assessment by the survival signature. This paper proposed a novel pattern of survival signature for the multi-state system with multiple types of components and the presented approach is executed to demonstrate the validity via a numerical case with 2-type and 3-state components.
Assessment of Cable Length Limit for Effective Protection by Z-Source Circuit Breakers in DC Power Networks

This paper introduces groundbreaking research on how to assess the Cable Length Limit (CLL) to ensure effective protection by Z-source Circuit Breakers (ZCBs) in DC power networks. It has been revealed that the line parameters of power cables have a significant impact on the cutoff performance of ZCBs. The question of assessing the CLL has been raised as an unsolved problem. In this paper, a method of CLL assessment is proposed based on physical models and simulation tests. To verify the proposed method, two studies were performed to assess the Cable Length Limits depending on fault levels and power delivery levels, respectively. The ZCB parameters were specified for a simulation testing system for a 5 MW distribution line feeder. The effectiveness of ZCB protection was tested in groups of simulation tests with various impacting quantities, i.e., cable lengths, fault current levels, and power delivery levels. The effective cable lengths for the ZCB to detect and successfully interrupt a faulty branch in the DC network were assessed and analyzed. The testing results prove that the CLL decreases along with a decreasing fault current level, as well as an increasing power delivery level. Based on data analysis, an equation was derived to calculate the effective length of the ZCB for DC lines, and the equation can be used to generate new CLL curves for various load-power requirements. This study could increase the reliability of a ZCB’s response to a fault in DC transmission and distribution lines. It could also help power system designers/operators to maintain reliable protection with ZCBs in DC power system networks.

Public Tendering Practices, Issues and Directions - A Case of Pakistan Construction Sector

Outdated tendering system is a significant obstacle in the momentum of public sector development in Pakistan. This study aims to examine various undiscovered part of public tendering through a detailed survey from key professionals, experts, and decision-makers of public projects. Furthermore, research covers the present status of public tendering in Pakistan and provides recommendations as per experts’ opinion. This paper exhaustively highlights how the classical customs of the public tendering in Pakistan could track the old-fashioned sector to an upright path. Intensive interviews and questionnaire surveys were carried out throughout the country for data compilation. The one-way ANOVA test was performed to verify the perception of various participants and to reject the null hypothesis. The study revealed various interesting facts of present-day situations of public tendering. Various pitfalls in public tendering were underlined in the speculation of experts. The study concluded that public tendering in Pakistan is crowded with severe threats that may be alarming for the future of the industry. Un-discovering of alarming facts about public tendering in Pakistan opens the directions for several researchers in terms of exploring project case studies further. The research is an eye-opener for policymakers, experts, decision-makers and governmental bodies to regulate the public tendering system accordingly.
Compact and Low-Coupled Tripolarized Microstrip MIMO Antenna Based on Parasitic Patch Loading

A miniaturized and low-coupled tripolarized microstrip multiple-input multiple-output (MIMO) antenna working at 3.5 GHz is proposed. This antenna includes a main circular radiating patch, which is shorted to the ground plane by an outer layer of vias, and a parasitic patch inside the cavity, which is connected to the main patch by an inner layer of vias. Through the selection of suitable number of the outer layer vias and the loading of the parasitic patch, the resonant frequencies of modes TM<sub>11</sub> and TM<sub>02</sub> can be reduced, individually. The design procedure of this antenna is demonstrated and a transmission-line model for TM<sub>02</sub> mode is presented, which can give a good explanation for the frequency reducing by the capacitance introduced by parasitic patch loading. This design can not only downsize the diameter of the unloaded antenna from <inline-formula> <tex-math notation="LaTeX">$0.7\lambda _{0}$ </tex-math></inline-formula> to <inline-formula> <tex-math notation="LaTeX">$0.485\lambda _{0}$ </tex-math></inline-formula>, with the same height of <inline-formula> <tex-math notation="LaTeX">$0.035\lambda _{0}$ </tex-math></inline-formula>, but also can reduce the interport coupling from −13 to −18 dB. The measured and simulated S-parameters and radiation patterns are in good agreements. Fine MIMO performance of the proposed tripolarized antenna in terms of large capacity and low correlation coefficients has been verified by some propagation measurements in a real-world office.
The Influence of Word-Of-Mouth Referral on Consumers’ Purchase Intention: Experimental Evidence from WeChat

Based on the perspective of dual-system information processing, this article explores how word-of-mouth (WOM) referral affects the purchase intentions of consumers with different types of self-construal. Two experimental studies, using WeChat as a research setting, tested the interactive influence of type of WOM referral (economic vs. public welfare) and type of self-construal (independent vs. interdependent) on consumers’ purchase intention toward the referred product and its intermediary mechanism. The results showed that economic (vs. public welfare) WOM referrals, which emphasize a product’s economic benefits, increased the purchase intention of consumers with an independent (vs. interdependent) self-construal, who typically take an individualistic perspective. In contrast, public welfare (vs. economic) WOM referrals, which emphasize the social benefits connected to a company for the community at large, increased the purchase intention of consumers with an interdependent (vs. independent) self-construal, who take a more collectivistic perspective. The results also shed light on the underlying mechanism by showing that different types of self-construal activate different information processing systems in consumers, which mediate consumers’ reaction to different types of WOM referrals. Specifically, economic WOM referrals can inspire consumers with an independent self-construal to engage in more emotional processing, thereby generating higher purchase intentions; in contrast, public welfare WOM referrals can stimulate consumers with an interdependent self-construal to get involved in more cognitive processing, thereby generating higher purchase intentions. These findings contribute to WOM literature and provide practical implications for companies adopting societal marketing strategy and implementing sustainable promotional plans.
Abundant transmission of Corona Virus Nsp2 RNA Topoisomerse I120F Mutants with Concurrence D614G Spike Protein Mutation in Australia

We previously predicted Nsp2 Corona virus protein as RNA topoisomerase through amino acid homology among Vibrio haemolytica DNA topoisomerase IA/IV as well as DNA primase, DNA gyrase and bi-subunit Trypanosoma brucei DNA topoisomerase IB. Many DNA topoisomerase I/III have RNA topoisomerase activity and such ubiquitous enzymes are conserved and involved in the regulation of replication and transcription. We have checked here mutational profile of Nsp2 RNA topoisomerase analyzing >10000 orf1a 4405 amino acid length Corona virus polyprotein. Mutant proteins were selected by BLAST search having 99.84% sequence similarity and 181-818aa portion Nsp2 protein (protein id. QIU82057) was analyzed using CLUSTAL Omega software. We found 26 different mutations where most changes were selected at Isoleucine and Alanine into Valine or Leucine into Phenylanaline pinpointing conserved nature of the Corona virus RNA topoisomerase. Major nonsense very abundant mutations were found at I120F (Isoleucine to Phenylalanine). Other important mutations were R27C, I198V, T85I, L410F, I559V and P583S. The I120F mutation was abundant in Australian isolates and its spread was seen in the Bangladesh and other countries like USA. We suggest that abundant I120F mutation of Nsp2 Topoisomerase may increase transmission of Corona virus by stabilizing RNA structure for efficient virus pakaging. Interestingly, such mutations were found in association of D614G mutation of Spike protein, known to >70% increase infectivity. On the contrary, all P583S Nsp2 mutants analyzed had no concurrence D614G spike protein mutation. Many silent mutations (5-7) were detected by genome wide analysis but no N501Y Spike protein mutation. This is first report that predicts a link of greater Corona virus transmission with Nsp2 protein I120F and spike protein D614G mutations.

Les fleurs des plants traitees au compost ont recues plus de visites d’insectes floricoles. Les feuilles des plants traites au compost etaient les plus endommages par les insectes ravageurs. Le traitement au compost favorise le developpement vegetatif, le developpement des floral ainsi que le rendement en graines et en fruits du gombo; cependant, attirent plus d’insectes ravageurs.
Chlorine and ozone disinfection and disinfection byproducts in postharvest food processing facilities: A review

Abstract The application of chemical disinfectants in postharvest food processing facilities is important for the control of foodborne pathogen outbreaks. Similar to drinking water disinfection, food processors will need to optimize disinfectant exposures to balance pathogen inactivation against exposure to potentially toxic disinfection byproducts (DBPs). Since most disinfection research has focused on drinking water, this review summarizes research related to disinfection in food washing facilities, particularly by chlorination and ozonation. Although these disinfectants are also used for drinking water, the conditions are significantly different at food processing facilities. After a brief summary of foodborne pathogen outbreaks, this review describes food processing treatment trains, particularly the critical differences in conditions encountered relative to drinking water disinfection (e.g., short disinfectant contact times and high and variable disinfectant demands). The review discusses research related to pathogen inactivation and DBP formation by chlorine and ozone during washing of produce, meat and seafood. In particular, the research highlights the difficulty of inactivating pathogens on food, but the efficacy of these disinfectants for controlling pathogen cross-contamination through the washwater. While most research on food-associated DBPs has focused on the same, low molecular weight DBPs of interest in drinking water, these DBPs partition to the washwater. This review highlights the need for research on the initial transformation products of disinfectant reactions with biomolecules, since these products may present a risk for consumer exposure by remaining within the food.

Changes in plant growth, leaf relative water content and physiological traits in response to salt stress in peanut (Arachis hypogaea L.) varieties

Salinity is the main environmental factor accountable for decreasing crop productivity worldwide. The effects of NaCl salinity on plant growth (leaf relative water content (RWC), leaf dry weight (LDW), shoot length (SL), number of leaves (NL), number of branches (NB) and total leaf area (TLA) and physiological characteristics (stomatal conductance (gs), transpiration rate (TR), net photosynthetic (Pn), yield of photosystem II (ΦPsII) and the intercellular CO2 concentration (CO2int) in peanut (Arachis hypogaea L.) varieties (‘Vanda’, ‘P244601’ and ‘Pl184948’, widely used in Cameroon, Tanzania and Ghana, respectively, were investigated under hydroponic condition. Plants were subjected to four levels of NaCl (0, 40, 80 and 120 mM) at early seedling growth stage of plant development. Application of NaCl treatment led to a significant decrease in LDW, SL, NL, TLA, Pn, gs, TR and CO2int concentration of ‘Vanda’ and ‘P244601’ compared to untreated plants while the plant growth inhibition was notably noted at 120 mM NaCl in ‘P1184948’ for LDW, SL and NB. The highest depressive effect was detected in gs of salt-sensitive ‘Vanda’ while the lowest were recorded in gs of salt-tolerant ‘P1184948’ at high salinity level. Enhanced NaCl concentrations led to a significant increase in ΦPSII of ‘P1184948’ compared to ‘Vanda’, ‘P244601’ and untreated plants. Leaf CHL content was significantly increased in moderately-tolerant ‘‘P244601’ and salt-tolerant ‘P1184948’ at 80 mM NaCl compared to salt sensitive ‘Vanda’ and untreated plants. The depressive effect of salt on RWC was recorded at 120 mM NaCl in peanut leaves of all varieties. Under salt stress ‘P1184948’ was observed to have relatively higher tolerance on average of all growth and physiological traits than ‘Vanda’ and P244601’ suggesting that it could be grown in salt-affected soils.
