Time-dependent evolution of the nitrogen configurations in N-doped graphene films

Large-area time-controlled N-doped graphene films were grown on a Cu foil using an ammonia-assisted atmospheric pressure chemical vapour deposition (APCVD) technique. The films were characterized using optical microscopy, Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). Raman spectroscopy was used to verify the doping level and lattice distortion in the graphene films, while the degree of N-doping (N/C at%) and nitrogen configuration were studied by XPS. The results showed that both total nitrogen content and configurations were strongly dependent on the growth time. Notably, at short growth time (2 min) pyridinic-rich films with high oxygen content (∼47.02%) were produced, and the total N-content reached a maximum of 4.68%. Interestingly longer growth times (20 min) also resulted in pyridinic-rich films, however both the nitrogen and oxygen content were at lower values of 2.84% and ∼26.07%, respectively. With increasing growth time, Raman spectra showed a decreasing doping level as seen by the decreasing ID/IG ratio values (1.2 to 0.9). Additionally, Raman peaks exhibited a systematic blue shift due to the compressive strain on the C–C bonds during the incorporation of N atoms into the graphene lattice. The study presents an in-depth understanding of how exposure time of N-dopants influences the bonding states of nitrogen atoms to carbon atoms, thereby dictating the resulting type of N-configurations as well as the overall nitrogen content.
Level of natural radiation in the closed space of the public schools in Hamadan, Iran (2015-2016)

Since human beings are constantly exposed to environmentalionizing radiations, the measurement of natural background radiations is of utmost importance. This cross-sectional, descriptive study aimed to measure the annual effective dose of natural background radiation in 93 schools in two districts of Hamadan, Iran in the winter, spring, and autumn of 2015-2016. Among the public schools in Hamadan, the schools located in district one with 1.41±0.079 mSv and district two with 0.955±0.04 mSv had the highest and lowest mean equivalent annual dose caused by natural radiation (γ rays) in a closed space, respectively. The mean equivalent annual dose caused by natural radiation in the closed space of all the public schools in districts one and two of Hamadan was estimated at 1.20±0.07 mSv as separated by geographical directions. In addition, the highest mean dose caused by natural gamma rays in the closed space of the school buildings constructed for more and less than 40 years was 1.42±0.22 and 1.42±0.15 mSv, respectively, and the rate of the effective annual dose of the public schools in Hamadan was determined to be 0.83 mSv as separated by district. The equivalent effective annual dose and risk of gamma ray cancer in the lifespan of the public school students in Hamadan was higher than the global average.

EDA‐based optimized global control for PV inverters in distribution grids

Operating distribution grids is increasingly challenging due to the increasing penetration of photovoltaic systems. To address these challenges, modern photovoltaic inverters include features for local control, which sometimes lead to suboptimal results. Improved communication infrastructure and photovoltaic inverters favour global control strategies, which receive information from all the systems in the grid. An estimation of distribution algorithm is used to optimize a global control strategy that minimizes active power curtailment and use of reactive power of the photovoltaic inverters, while maintaining voltage stability. Optimized global control outperforms every other local control evaluated in terms of apparent energy used for control (9.9% less usage compared to the second best alternative in all scenarios studied) and ranks second in terms of voltage stability (with a 0.14% of total time outside the voltage limits). Two new indicators to compare control strategies are proposed, and optimized global control strategy ranks best for both efﬁciency index (0.98) and average apparent power use (0.48
Compact Stars Admitting Noether Symmetries in Energy-Momentum Squared Gravity

This paper investigates the geometry of compact stellar objects through the Noether symmetry approach in the energy-momentum squared gravity. This newly developed theory overcomes the problems of big bang singularity and provides the viable cosmological consequences in the early time universe. Moreover, its implications occur in high curvature regime where the deviations of energy-momentum squared gravity from general relativity is confirmed. We consider the minimal coupling model of this modified theory and formulate symmetry generators as well as corresponding conserved quantities. We use conservation relation and apply some suitable initial conditions to evaluate the metric potentials. Finally, we explore some interesting features of the compact objects for appropriate values of the model parameters through numeric analysis. It is found that compact stellar objects in this particular framework depend on the model parameters as well as conserved quantities. We conclude that Noether symmetries generate solutions that are consistent with the astrophysical observational data and hence confirm the viability of this procedure.
Domestic Animal Welfare at the Zoo: The Impact of an Animal Visitor Interaction Program on Chickens

Many modern zoos strive to create connections between guests and animals through animal visitor interaction (AVI) programs. However, there has been relatively little research into the effect of AVI programs on the welfare of program animals. Previous research has revealed three factors that may affect AVI program animal welfare: species differences, handling and transport, and the provision of choice and control. We assessed the effects of an AVI program designed with these factors in mind on the behavior of a flock (N = 16) of zoo-housed domestic chickens (Gallus gallus). Behavioral data were collected on program days and on non-program (control) days, and we considered the time leading up to the program, the program itself, and the time immediately following the program. When comparing flock behavior on program days to control days, we found no differences in behavioral indicators of welfare during the time leading up to the program and during the program. Rates of aggression, however, were significantly greater after the program had concluded compared to the same time period on matched control days, but still occurred infrequently. Additionally, we recorded the spatial location of each animal while the program occurred and found that the chickens did not spend significantly more or less time in the feeding zone as visitor participation increased, although there were individual differences within the flock. We conclude that the relatively small behavioral changes seen were not indicative of a change in welfare and consider those results in the context of the program design.
Baby tyrannosaurid bones and teeth from the Late Cretaceous of western North America

Tyrannosaurids were the apex predators of Late Cretaceous Laurasia and their status as dominant carnivores has garnered considerable interest since their discovery, both in the popular and scientific realms. As a result, they are well studied and much is known of their anatomy, diversity, growth, and evolution. In contrast, little is known of the earliest stages of tyrannosaurid development. Tyrannosaurid eggs and embryos remain elusive, and juvenile specimens — although known — are rare. Perinatal tyrannosaurid bones and teeth from the Campanian–Maastrichtian of western North America provide the first window into this critical period of the life of a tyrannosaurid. An embryonic dentary (cf. Daspletosaurus) from the Two Medicine Formation of Montana, measuring just 3 cm long, already exhibits distinctive tyrannosaurine characters like a “chin” and a deep Meckelian groove, and reveals the earliest stages of tooth development. When considered together with a remarkably large embryonic ungual from the Horseshoe Canyon Formation of Alberta, minimum hatchling size of tyrannosaurids can be roughly estimated. A perinatal premaxillary tooth from the Horseshoe Canyon Formation likely pertains to Albertosaurus sarcophagus and it shows small denticles on the carinae. This tooth shows that the hallmark characters that distinguish tyrannosaurids from other theropods were present early in life and raises questions about the ontogenetic variability of serrations in premaxillary teeth. Sedimentary and taphonomic similarities in the sites that produced the embryonic bones provide clues to the nesting habits of tyrannosaurids and may help to refine the prospecting search image in the continued quest to discover baby tyrannosaurids.
Limited predictive power of DAT mRNA mappings for DAT protein expressions

Background Dopamine transporter (DAT) is a transmembrane protein that translocates dopamine from the extracellular space into the presynaptic neurons. We aimed to investigate the predictive power of DAT mRNA for DAT protein expression measured from positron emission tomography (PET). Methods Thirty-five healthy subjects were imaged with 18F-FP-CIT PET. Binding potential (BPND) from ventral striatum, caudate nucleus, putamen, middle frontal, orbitofrontal, cingulate, parietal, temporal cortices were measured. DAT gene expression investigated in this study was obtained from the freely available Allen Human Brain Atlas (www.brain-map.org) derived from 6 healthy donors. Results PET-derived BPNDs from 35 subjects, and DAT mRNA expressions of 6 probes from 6 subjects were included in this study. The auto-correlation of PET-derived BPNDs for DAT was intermediate (mean 𝛒2 = 0.6588) with 𝛒2 ranging from 0.0811 to 1. However, the auto-correlation of mRNA expression was weak across the probes with mean 𝛒2 from 0.0889 to 0.2263. Cross-correlations between PET-derived BPNDs, and mRNA expression were weak with mean 𝛒2 ranging from 0.0011 to 0.2220 across the probes. Conclusion we observed weak associations between DAT mRNA expressions, and DAT protein expressions in human brains. Therefore, there might be a limited predictive power of DAT mRNA mappings for DAT protein expressions in humans.
Dense spatio-temporal stereo matching for intelligent driving systems

This paper addresses the problem of matching stereo images acquired by a stereo system mounted aboard an intelligent vehicle. The main idea behind the new method consists in involving temporal matching between a current stereo pair and its preceding one to achieve the spatial matching of the former stereo by involving the matching results obtained at the last frame. The proposed method is achieved in three main steps. First, an edge based disparity map is derived from the disparity map of the preceding frame, we call it the assisting disparity map (ADM). Second, for each scan-line, a set of local ranges and global ranges are deduced from the ADM to keep only potential matching candidates. Third, the matching is done on the basis of dynamic programming algorithm by involving in the resulting local and global ranges we get from the last step. The proposed approach has been tested on both real and synthetic stereo sequences and the results demonstrate its effectiveness.
Donors’ perceptions of financial disclosures and links to donation intentions

ABSTRACT The not-for-profit literature has not fully explored the decision-usefulness of financial disclosures with respect to the public’s donation intentions. Engaging with this lacuna, this study proposes that reputation and trust serve as important causal links between donors’ perceptions of the decision-usefulness of financial disclosures and their donation intentions. The study adopts the theory of planned behaviour and applies structural equation modelling to 400 useable responses from an Australian survey. The study finds: (1) a strong link between financial disclosures which donors perceive as decision-useful and their perception of the reputation of the reporting not-for-profit organisation (NFP), (2) a close association between donors’ perception of the reputation of an NFP (that is, their behavioural belief) and their trust in the organisation (their attitude), and (3) a significant link between donors’ trust in an NFP and hence their attitude towards the organisation with respect to their donation intentions. These results imply that the decision-usefulness of an NFP’s financial disclosures make donors more inclined to donate to the NFP via the impact of disclosures on donors’ perceptions of reputation and thence trustworthiness. In addition to contributing to the emergent NFP literature on disclosures and giving behaviour, these findings inform financial disclosure policies and practice by furthering the case for decision-useful financial disclosures among NFPs.
Wavelet Analyses of Geomagnetic Data regarding Major Geomagnetic Disturbances

The purpose of this study was to analyze the associated spectrum of geomagnetic field, frequencies intensity and the time of occurrence. We calculated the variation of the correlation coefficients, with mobile windows of various sizes, for the recorded magnetic components at different latitudes and latitudes. The observatories we included in our study are USA (Surlari), HON (Honolulu), SBA (Scott Base), KAK (Kakioka), THY (Tihany), UPS (Uppsala), WNG (Wingst) and Yellowknife (YKC). We used the data of these observatories from International Real-time Magnetic Observatory Network (INTERMAGNET) for the geomagnetic storm from October 28-31, 2003. We have used for this purpose a series of filtering algorithms, spectral analysis and wavelet with different mother functions at different levels. In the paper, we show the Fourier and wavelet analysis of geomagnetic data recorded at different observatories regarding geomagnetic storms. Fourier analysis hightlights predominant frequencies of magnetic field components. Wavelet analysis provides information about the frequency ranges of magnetic fields, which contain long time intervals for medium frequency information and short time intervals for highlight frequencies, details of the analyzed signals. Also, the wavelet analysis allows us to decompose geomagnetic signals in different waves. The analyses presented are significant for the studies of the geomagnetic storm. The data for the next days after the storm showed a mitigation of the perturbations and a transition to quiet days of the geomagnetic field.
Sexually Dimorphic Expression and Special Regulatory Sequence of Dnali1 in the Olive Flounder Paralichthys Olivaceus

Dynein axonemal light intermediate chain 1 (dnali1) is an important part of axonemal dyneins and plays an important role in the growth and development of animals. However, there is little information about dnali1 in fish. Herein, we cloned dnali1 gene from the genome of olive flounder (Paralichthys olivaceus), a commercially important maricultured fish in China, Japan, and Korea, and analyzed its expression patterns in different gender fish. The DNA sequence of the entire gene contained a 771 bp open reading frame (ORF), two different sizes of 5' untranslated region (5'UTR), and a 1499 bp 3' untranslated region (3'UTR). Two duplicated 922 nt fragments were found in dnali1 mRNA. The first fragment contained the downstream coding region and the front portion of 3'UTR, and the second fragment was entirely located in 3’UTR. Multiple alignments indicated that the flounder Dnali1 protein contained the putative conserved domain. Its expression showed sexually dimorphic with predominant expression in the flounder testis, and lower expression in other tissues. The gene with the larger 5’UTR was specifically expressed in the testis. The highest expression level in the testis was detected at stages Ⅳ and Ⅴ. Transient expression analysis showed that the 922 bp repeated sequence 3’UTR of dnali1 down-regulated the expression of GFP at the early stage in zebrafish. The results implied that dnali1 might play an important role in flounder testis, especially in the period of spermatogenesis, and the 5’UTR and the repetitive sequences in 3’UTR might contain some special regulatory elements for the cilia.
Photogrammetry using Intelligent-Battery UAV in Different Weather for Volcano Early Warning System Application

We have developed a new volcano early warning system based on sensor node, internet of things (IoT) and UAV to overcome some problems in Indonesian volcano monitoring system. Data (monitored by sensor node) transmission and communication is managed by the IoT while UAV is used for remote sensing data to complete the system to predict the geological status of the volcano. An intelligent-battery UAV is needed for this purpose which manage the power utilization for field application. First stage of the remote sensing process is volcano region mapping for constructing an orthophoto before it is combined with field sensor data. Therefore, we have conducted a laboratory experiment to map some region in ITB, Bandung in different weather as real volcano condition. We have constructed day, night, sunny and cloudy maps of ITB after some data collected through flight and control plan as real volcano environment. Some grid flight plans were chosen for expected result as well as battery saving for each 5 meters data collection. A 3D software has been used for modelling of the orthophoto construction and resulted in 0 – 8 meters error of 20000 – 24000 m2 monitored area. Therefore, this method could be used in real volcano application.
An Analysis of the Impact of Automation on Supply Chain Performance in Logistics Companies

While many companies currently seek technology for penetration into the sector, precision and efficiency while speeding up the processes at the same time, the performance of the supply chain is confronted by numerous challenges that can hinder its performance. This essay discusses the issues and questions resulting from an automated approach employed by industrial companies. The method thus has a considerable influence on the supply chain’s performance, taking account of internal synchronization. After multiple interviews with two companies, an interactive process was developed. The outcomes of the study were extracted from the variables associated with the exam. We have already seen various statistics that indicate that automation has eliminated manufacturing costs, human bugs and a somewhat time-consuming process for supply chains. Although the quality and effectiveness of employees have improved, cooperation between departments and resources and time taken with each job has also improved.
Analysis of Custom IoT Based Electricity Monitoring System

Electricity is a resource that currently exists in various sectors of the community. Each person’s electricity needs are different depending on the needs of the electronic equipment used. Excessive use of electronic equipment creates extreme electrical power. Electricity consumption is an issue that discussed since a long ago. This research aims to present a custom electronic sensor to monitor electricity consumption based on the Internet of Things. It also explained the correlation between input and output points from the custom electronic sensor. This research method consists of 4 steps: system requirement, system design, system implementation, and last, testing and analysis. The system developed is able to get the current, voltage, and power data. The data then processed by Arduino UNO and directly send by ESP8266 to Blynk Application on Android smartphones via Internet communication.

Socially responsible human resource practices and hospitality employee outcomes

This paper aims to unfold the mediation mechanism of job crafting, through which socially responsible human resource practices (SRHR practices) influence work meaningfulness and job strain among hospitality employees. It also seeks to unravel the moderating effect of authentic leadership on this indirect relationship. ,Three survey waves were conducted to collect data from 825 employees and 128 managers from 34 four- or five-star hotels in two major cities in Vietnam. The data were analyzed through structural equation modeling to test the hypothesized relationships. ,The results lent credence to the positive relationship between SRHR practices and employees’ meaningfulness of work as well as the negative nexus between SRHR practices and employees’ job strain. These relationships were mediated by employee engagement in job crafting. The results further revealed that authentic leadership functioned as a negative moderator for the impact of SRHR practices on job crafting as well as the indirect effects of SRHR practices on the two employee outcomes via job crafting. ,The findings suggest to hospitality organizations that employees may find their work more meaningful and less stressful if they implement SRHR practices to enable them to craft their tasks. Hospitality organizations should also realize the role of authentic behavior among managers in stimulating employee job crafting behavior particularly when SRHR practices are not fully in place. ,This study advances the understanding of the mechanisms that translate SRHR practices into hospitality employee outcomes. This work also extends the contingency perspective in the HRM literature by unraveling authentic leadership as a contingency for the impacts of SRHR practices.
DETERMINANTS OF CORPORATE PROFITABILITY OF COMPANIES FROM CONSTRUCTION AND REAL ESTATE INDUSTRIES IN SELECTED EUROPEAN COUNTRIES

The basic economic rule in any business should be profit maximization and also each business entity establishes a company in order to generate profit from invested funds. So, profitability indicators have a significant position among the criteria of economic activity. Achieving profitability is influenced by a myriad of determinants. This study focuses on some external determinants. The subjects of the research are companies from eight European economies, which come from two sectors, namely construction and real estate activities, which are divided into twelve groups according to the NACE classification. The aim of the research is to use Generalized Method of Moments to find out whether selected determinants affect corporate profitability or not. The determinants are as follows: GDP growth rate, inflation rate, basic interest rate, unemployment rate, gross fixed capital formation. The research covers the period 2010–2018. In total, over 89,000 companies are surveyed. There is at least one main finding, namely the greatest influence on the level of profitability in the construction and real estate activities sectors has the basic interest rates of individual economies and that this effect is mostly negative.
