Toward high efficiency tin perovskite solar cells: A perspective

The development of high-performance lead-free perovskite solar cells (PSCs) is important to address the environmental concern of lead perovskite. In recent years, tin perovskite solar cells (TPSCs) have been developing quickly and emerging as a promising candidate for high-efficiency lead-free PSCs. In this Perspective, we summarize recent work of our group including the use of a low-dimensional structure, film growth kinetic control, and device engineering. In the end, the challenges in TPSCs and potential strategies toward high-efficiency TPSCs are discussed.
Personality is correlated with natal dispersal in North American red squirrels ( Tamiasciurus hudsonicus )

Individual natal dispersal behaviour is often difficult to predict as it can be influenced by multiple extrinsic and intrinsic factors. Individual differences in personality have been shown to be an important correlate of dispersal behaviour. However, the relationships between personality traits and dispersal are often inconsistent within and across studies and the causes of these discrepancies are often unknown. Here we sought to determine how individual differences in activity and aggression, as measured in an open-field trial, were related to natal dispersal distance in a wild population of North American red squirrels ( Tamiasciurus hudsonicus ). For 14 cohorts, while individual aggression consistently had no association with dispersal distance, the association between activity and dispersal fluctuated through time, mediated by population density. The environmental-dependence of the relationship between personality and dispersal in this population is indicative of the importance of considering external conditions when predicting dispersal behaviour.
Quality Evaluation of EPC to BPMN Business Process Model Transformation

Due to the expressiveness of BPMN for representing the business processes, it has replaced EPC as a de-facto process modelling standard. As such, enterprises require to transform their existing EPC business process models to BPMN to keep their competitiveness. ARIS Architect & Designer, as a popular business process modelling tool, provides a model transformation feature, e.g., EPC to BPMN. For the sake of quality, it must guarantee that the resulting model has syntactic correctness and syntactic completeness. However, there is currently limited scientific approach available to evaluate the quality of the model transformation in ARIS Architect & Designer. This study proposes an evaluation of model transformation in ARIS Architect/Designer based on syntactic correctness and syntactic completeness criteria using an experimental approach. The result shows the model transformation in ARIS Architect/Designer has not completely fulfilled the criteria. The result opens further research challenges to improve the quality of EPC to BPMN model transformation.
Proximate Analysis Of Maggot Flour Fermentation Results Using Aspergillus niger and Trichodema viride

The purpose of this study was to determine the nutritional properties of maggot flour fermented microbiologically using Aspergillus niger and Trichoderma viride fungi at different dosage, especially on increasing protein, decreasing fat and fiber. The maggot used is derived from culture in a mass on the oil palm cake media for 7-10 days, the maggot harvest is dried and then ground and sieved. As a fermentor material, A. niger is inoculated on PDA (Potato Dextrose Agar) media added with yeast extract 0.3% with a sloping agar method, for propagation using rice as a medium, while for T.viride using PCA (Plate Count Agar) media. Then taken as much as 15% and 20% for the fermentation process of maggot flour. Based on the results of proximate analysis, produced 43.27% crude protein, crude fat to 6.66% and crude fiber 14.11% in A.niger fungi, while T. viride results in protein content of 39.19%, the reduction in fat content is relatively small at 24.21%, the value of fiber content becomes lower that is 11.75. The highest percentage reduction in fat content in A. niger, and crude fiber in T.viride. The difference in dosage does not affect the results of proximate analysis of both A.niger and T.viride.
Occurrence of Human Norovirus GII and Human Enterovirus in Ontario Source Waters

Occurrence of Human Norovirus and Human Enterovirus in Ontario Source Waters Cassandra Diane LoFranco Advisors: H. Lee University of Guelph, 2017 M. Habash S. Weir Norovirus and Enterovirus are common human viral pathogens found in water sources. Despite causing gastroenteritis outbreaks, most jurisdictions, including Ontario, do not monitor for enteric viruses in waters. The objective of this thesis was to monitor the presence of human Norovirus and Enterovirus in Ontario source waters intended for drinking. Two untreated source water types (river and ground water) were sampled routinely and following precipitation and snow melt events between January 2015 and April 2016. Physical, chemical, microbiological, and meteorological data were collected, coinciding with sampling events. A modified USEPA Method 1615 was applied to detect and quantify viruses and logistic regression was used to examine relationships between virus presence and environmental
Occurrence of coral diseases at Akajima, Okinawa, Japan in 2010 and 2011

We conducted a survey of coral diseases at two sites at Akajima, Kerama islands, Okinawa, Japan in 2010 and 2011. Diseased colonies recorded in both years were categorized into four types, namely, Black Band Disease (BBD), Skeleton Eroding Band (SEB), Growth Anomalies (GA) and White Syndrome (WS), and BBD on encrusting Montipora spp. was the dominant disease. We therefore focused on the BBD on Montipora spp. and analyzed the distribution of BBD-diseased colonies and the progression of BBD bands. Results revealed that the BBD distribution showed significant small-scale clustering in both years. The progressive band showed four morphological patterns on the same individual, and the composition of band patterns changed throughout the observation periods. The maximum progression rates were approximately 3 to 5 fold greater than the minimum rate at the same sites and times. These results suggest that BBD-diseased colonies at Akajima are aggregated and show different responses to factors related to BBD progression, even at the single-reef scale.
Green Technology and Sustainable Development: Assessment and Green Growth Frameworks

The aim of this study is to investigate the characteristics of a sustainable development assessment methodology being designed in the context of green technology. The methodology in question is based on indicators from the Sustainable Development Goals Index (SGDI), specifically in its ecological component. These indicators underlie an Averaging Sustainable Development Index (ASDI) and a Normalized Sustainable Development Index (NSDI). The resultant methodology was applied to 20 countries from the SDGI ranking. According to the research results, the intensive activity of the brown industries in the United Arab Emirates, Kazakhstan, the United States, Korea, and Russia resulted in significant carbon dioxide emissions. Switzerland, Kazakhstan, and Russia had high scores on sustainable management of water and sanitation. Russia was the only developed country to have an ASDI higher than its SDGI and its gap between NSDI and ASDI indexes was not significant, indicating a positive trend in greentech development. The reason why NSDI was increasingly different from SDGI was that countries leading the socio-economic rankings had higher consumption of energy and resources, and a much greater environmental footprint than those countries that consumed less. The originality of this study is that it identifies gaps between NSDI and ASDI values, which indicate that conditions for greentech adoption in most developing countries are unfavorable.
Export, Political Stability, and Growth in Developing-8 Countries

The relationship between growth in export and economic growth is still a current issue in both the theoretical and empirical literature. Besides, there are also non-economic factors that determine economic growth in a country, namely political stability. This study aims to examine the impact of export and political stability on economic growth in D8 member countries. The research on the development of the D8 country's economy is still minimal, so this research expected to be able to contribute to drafting policies for D8 member countries. By using panel regression, this research finds that there is no impact between export on economic growth. However, political stability had an impact on economic growth in developing-8 countries. This result implies that the government should increase political stability to accelerate growth
Regulation of Fruiting In Plum Production

This short overview article describes different strategies to adjust crop loads in plums in order to get regular cropping, improve fruit size and fruit quality. There are three principal methods of regulating the crop loads of plum, which can be combined: numbers of flowers on the tree can be reduced, flowers can be prevented from fruit setting and the amount of fruitlets can be reduced by thinning methods. The methods of achieving these strategies, by manual, mechanical and chemical means are described and discussed.
Balancing Narrow and Broad Public Service Professionalism: Experience With the New Zealand G-REG Qualifications Framework

For many years, governments around the globe have been called on to increase the professionalism of their public services. The New Zealand Government Regulatory Practice Initiative (G-REG) is an illustrative example of a network of government agencies responding to this call by providing a program of standardized training for public servants. This article maps, explores, and interrogates this example to obtain a better understanding of whether a standardized program can help to nurture and increase the professionalism of a community of public servants. It finds that the main challenge of such an undertaking is finding a balance between narrow professionalism (technical expertise and knowledge) and broad professionalism (acting proficiently and ethically).
Adolescents perception of the impact of condom use on sexual behaviours: Evidence from Ghana, a developing country

Adolescence is a critical stage in human life. Adolescents’ perception of the impact of condom use on sexual behaviour has been studied in developed countries. However, not much is known about this phenomenon in Ghana. The study investigates the perception of adolescents regarding the impact of condom use on sexual behaviours. Simple random and stratified sampling techniques were employed to select the study respondents. The data were analysed using descriptive and inferential statistics. The study revealed that adolescents’ knowledge level about condom use was above average (>2.50). Again, the adolescents’ knowledge level about condom use predicted their sexual behaviours (β = 0.159, p=0.000). It is concluded that adolescents possess adequate knowledge about condom use. It is recommended that more stakeholders should be involved in the provision of knowledge on condom use among adolescents in Ghana. Key words: Adolescents, adolescence, perception, knowledge level, condom use, sexual behaviours, Ghana.
Detecting myrtle rust (Austropuccinia psidii) on lemon myrtle trees using spectral signatures and machine learning

Hundreds of species in one of Australia's dominant plant families, the Myrtaceae, are at risk from the invasive pathogenic fungus Austropuccinia psidii. Since its arrival in Australia in 2010, native plant communities have been severely affected, with highly susceptible species likely to become extinct from recurring infections. While severe impact on Australian native and plantation forestry has been predicted, the lemon myrtle industry is already under threat. Commercial cultivars of lemon myrtle (Backhousia citriodora) are highly susceptible to A. psidii. Detecting and monitoring disease outbreaks is currently only possible by eye, which is costly and subject to human bias. This study aims at developing a proof-of-concept for automated, non-biased classification of healthy (naive), fungicide-treated and diseased lemon myrtle trees by means of their spectral reflectance signatures. From a lemon myrtle plantation, spectral signatures of fungicide-treated and untreated leaves were collected using a portable field spectrometer. A third class of spectra, from naive lemon myrtle leaves that had not been exposed to A. psidii, was collected from a botanical garden. Reflectance spectra in their primary form and their first-order derivatives were used to train a random forest classifier resulting in an overall accuracy of 78% (kappa = 0.68) for primary spectra and 95% (kappa = 0.92) for first-order derivative-transformed spectra. Thus, an optical sensor-based discrimination, using spectral reflectance signatures of this as yet uninvestigated pathosystem, seems technically feasible. This study provides a foundation for the development of automated, sensor-based detection and monitoring systems for myrtle rust.
Major stopover regions and migratory bottlenecks for Nearctic-Neotropical landbirds within the Neotropics: a review

Summary Nearly 300 species of landbirds, whose populations total billions, migrate between the Neotropics and North America. Many migratory populations are in steep decline, and migration is often identified as the greatest source of annual mortality. Identifying birds’ needs on migration is therefore central to designing conservation actions for Nearctic-Neotropical migratory birds; yet migration through the Neotropics is a significant knowledge gap in our understanding of the full annual cycle. Here, we synthesise current knowledge of Neotropical stopover regions and migratory bottlenecks, focusing on long-distance, migratory landbirds that spend the boreal winter in South America. We make the important distinction between “true” stopover—involving multi-day refuelling stops—and rest-roost stops lasting < 24 hours, citing a growing number of studies that show individual landbirds making long stopovers in just a few strategic areas, to accumulate large energy reserves for long-distance flights. Based on an exhaustive literature search, we found few published stopover studies from the Neotropics, but combined with recent tracking studies, they describe prolonged stopovers for multiple species in the Orinoco grasslands (Llanos), the Sierra Nevada de Santa Marta (Colombia), and the Yucatan Peninsula. Bottlenecks for diurnal migrants are well described, with the narrowing Central American geography concentrating millions of migrating raptors at several points in SE Mexico, Costa Rica, Panama and the Darién. However, diurnally migrating aerial insectivores remain understudied, and determining stopover/roost sites for this steeply declining group is a priority. Despite advances in our knowledge of migration in the Neotropics, we conclude that major knowledge gaps persist. To identify stopover sites and habitats and the threats they face, we propose a targeted and collaborative research agenda at an expanded network of Neotropical sites, within the context of regional conservation planning strategies.
Preparation and Electrochemical Properties of Functionalized Multi-Walled Carbon Nanotubes @ Carbon Quantum Dots @ Polyaniline Ternary Composite Electrode Materials

Based on various carbon nano materials, the ternary composite functionalized carbon nanotubes (FMWCNTs) @ carbon quantum dots (CQDs) @ polyaniline (PANI) was prepared by in-situ polymerization and hydrothermal method. The carbon-based material was made into an electrode sheet. The morphology and microscopic nanostructures were characterized by FTIR, field emission scanning electron microscopy and field emission transmission electron microscopy. Cyclic voltammetry and the galvanostatic charge discharge method was adapted to study the electrochemical properties of these active materials. Our results showed that the specific capacitance of FMWCNTs @ CQDs @ PANI was as high as 534 F/g, while it was 362 F/g, 319 F/g and 279 F/g for PANI @ FMWCNTs, PANI @ CQDs and polyaniline. This means that the specific capacitance of FMWCNTs @ CQDs @ PANI is increased by 47.5%, 67.4% and 91.4% comparing with the capacitance of PANI @ FMWCNTs, PANI @ CQDs and polyaniline, respectively. Moreover, the specific capacitance retention rate of the ternary active electrode after 1000 times of constant current charge and discharge cycle reached 86%, while it was 60% for PANI @ FMWCNTs, 72% for PANI @ CQDs and 65% for polyaniline.

Empatía y rendimiento académico en estudiantes universitarios

Empathy is important for peaceful coexistence, it is believed that it is associated with academic performance, for this reason it is intended to correlate the level of empathy with the academic performance of students in the Primary Education Specialty, Faculty of Education Sciences, National Hermilio University Valdizan, Huanuco, Peru. A descriptive correlational study was carried out, the documentary analysis technique was used to collect information on the students' qualifications and the survey to collect information on empathy, using the Interpersonal Reactivity Index questionnaire. The relationship between the variables was determined using the Pearson's Correlation Coefficient. The results showed a non-significant correlation between empathy and level of academic performance, showing that the university does not contribute to developing empathy, if it were so, the students with the highest scores would have better levels of empathy.
Unfolding ‘big’ problems of small water system performance: a qualitative study in British Columbia

Abstract In this study, small water systems (SWSs) serve a population of less than 5,000. This paper includes responses to a qualitative questionnaire from 66 SWSs (33% out of 200 SWSs) that identify the major problems within these systems across British Columbia (BC). Focusing on four interrelated components of SWSs (water quality issues, treatment and disinfection, water quality monitoring and water governance challenges), the identified major problems include: insufficient water monitoring programs; inadequate treatment prior to disinfection; insufficient funds to build water infrastructure; high turbidity; iron and manganese in source water; microbial contamination, especially in distribution networks; and high disinfection by-product formation. Based on the findings, the authors recommend implementing efficient water policies suitable for SWSs and strengthening funding support from governments. Developing long-term plans for effective management of water resources, while building strong communication among relevant stakeholders (ie municipal managers, operators and consumers), can also play a significant role in ensuring safe drinking water supplies. The findings can help BC policymakers understand the major problems of SWSs and their root causes.

Improving the performance of processing special computing tasks using an asynchronous actor model

The use of third-party ready-made solutions to perform special computing tasks (SCT): processing text arrays in a natural language, the use of cryptography methods in data transmission networks, machine learning in solving applied problems, scientific computations and many other ones is a common practice in modern development of software systems. However, the use of third-party ready-made software solutions often leads to their poor optimization for parallel and distributed operation and to the difficulty in vertical and horizontal scaling, impossibility of modifying a solution, e.g., due to its legal protection, etc. In order to solve these problems, an asynchronous actor model can be used that facilitates developing software for processing special computing tasks. In addition, an asynchronous actor model allows parallel processing of input tasks, provides asynchronous operation, and extends its functionality to third-party ready-made solutions, that it is impossible or forbidden to modify to meet user’s or optimization requirements. Methods, algorithms, and the entire logic of asynchronous actor operation involve transitions of actors from one state to another under the effect of input messages and returning the results of processed tasks to the frame system. This allows setting an automatic grammar and for using methods and approaches for developing software systems based on finite-state automata. The asynchronous actor operation scheme is represented by a directional state graph, which allows using the mathematical apparatus of the finite-state automaton theory (the Mealy model) to describe the same. The developed model is convenient for designing and organizing the SCT processing using computer systems. The use of the asynchronous actor model makes it possible, in special operation modes, to increase the performance of poorly optimized SCT without modifying the same, as compared to task processing without using the asynchronous actor model.
Effects of Climate Change on Marine Organisms

Global warming has become a global challenge having dire consequences on different aspects of the environment due to the melting of glaciers, excess carbon dioxide (CO2), and excess warming of water bodies among others. At a faster pace recently, climate change is affecting the marine environment, causing numerous alterations. Here, we address its consequences and the numerous alterations, which are more vital for researchers and global agencies to advocate more on why it’s essential to lessen the impact of climate change. Our review showed that the impacts of climate change are articulated at several stages of the marine ecosystem where it affects the inhabitants and their habitats. In response to climate change (ocean warming) marine species shift their latitudinal range to find suitable conditions leading to the redistribution of species. In addition, we found that growth reduction, sub-optimal behaviors, and reduced immune-competence of marine organisms, are as a result of thermal stress due to climate change. Also, the periodic changes in temperature above or below the optimum have a meditative reproductive effect on marine species, including fish. Finally, we discovered that due to higher water temperatures, several diseases showcase greater virulence in the sense that the marine species become less resistant to these diseases due to stress, increased virulence stimuli, or increased transmission.
