Biodegradation Pathway of Acid Red 27 by White‐Rot Fungus Armillaria sp. F022 and Phytotoxicity Evaluation

Armillaria sp. F022, a basidiomycete fungus isolated from a recreational forest in Johor, Malaysia, was tested for its biodegradation ability of the azo dye Acid Red 27 (AR27). Varying carbon and nitrogen sources, agitation, and inoculum concentrations on AR27 dye degradation by Armillaria sp. F022 in liquid medium were investigated to find out their effects on dye degradation. Glucose and ammonium chloride were the best nutrients for the growth of Armillaria sp. F022. The addition of 15% inoculum concentration of Armillaria sp. F022 increased the AR27 dye degradation up to 97.17% within 72h of incubation. Phytotoxicity tests were performed employing seed germination of Sorghum vulgare and Triticum aestivum by monitoring their elongation of the plumules and radicles to evaluate the toxicity of the degradation products. The metabolites formed during biodegradation were 1,4-naphthalenediol, 1,2-dihydroxynaphthalene, and coumarin, characterized by thin-layer chromatography and gas chromatography-mass spectrometry. Based on the findings of the AR27 biodegradation pathway it is proposed that Armillaria sp. F022 can be used to treat AR27 dye contaminated effluents to protect the ecosystem.
Forest Fire Susceptibility Prediction Based on Machine Learning Models with Resampling Algorithms on Remote Sensing Data

This study predicts forest fire susceptibility in Chaloos Rood watershed in Iran using three machine learning (ML) models—multivariate adaptive regression splines (MARS), support vector machine (SVM), and boosted regression tree (BRT). The study utilizes 14 set of fire predictors derived from vegetation indices, climatic variables, environmental factors, and topographical features. To assess the suitability of the models and estimating the variance and bias of estimation, the training dataset obtained from the Natural Resources Directorate of Mazandaran province was subjected to resampling using cross validation (CV), bootstrap, and optimism bootstrap techniques. Using variance inflation factor (VIF), weight indicating the strength of the spatial relationship of the predictors to fire occurrence was assigned to each contributing variable. Subsequently, the models were trained and validated using the receiver operating characteristics (ROC) area under the curve (AUC) curve. Results of the model validation based on the resampling techniques (non, 5- and 10-fold CV, bootstrap and optimism bootstrap) produced AUC values of 0.78, 0.88, 0.90, 0.86 and 0.83 for the MARS model; 0.82, 0.82, 0.89, 0.87, 0.84 for the SVM and 0.87, 0.90, 0.90, 0.90, 0.91 for the BRT model. Across the individual model, the 10-fold CV performed best in MARS and SVM with AUC values of 0.90 and 0.89. Overall, the BRT outperformed the other models in all ramification with highest AUC value of 0.91 using optimism bootstrap resampling algorithm. Generally, the resampling process enhanced the prediction performance of all the models.
Barriers and Benefits of ICT Adoption in the Nigerian Construction Industry. A Comprehensive Literature Review

Information and Communication Technology (ICT) is seen as a way to enhance knowledge collection in the construction sector. Although the theoretical benefits of ICT implementation have been clarified, realizing such benefits is insufficient. This paper attempted a systematic analysis of the literature using ATLAS.ti 9 software to save, identify, and analyze this study’s data. A total of 102 articles were actively reviewed, including 82 Scopus journals and 20 conference papers published from 2003 to 2020. In this article, from a construction industry point of view, the ICT adoption process is considered as an interaction between technology, task, and an individual from a construction industry perspective. While ICT is acknowledged as a source of aggressive gain by both practitioners and scholars, ICT’s sole presence would definitely not guarantee achievement in the industry’s ICT approval. Companies cannot grasp the full benefits of ICT, except that users are able to adopt the technology. Hence, the issues related to ICT adoption need to be examined.
Transparency and Accountability: Causal, Critical and Constructive Perspectives

Given the excessive power of Google and other large technology firms, transparency and accountability have turned into matters of great concern for organization scholars. So far, most studies adopt either a causal or critical perspective on the relationship between the two concepts. These perspectives are pitted against each other but share some basic assumptions – a fact which limits organization theory’s ability to fully grasp the management of (digital) visibilities. To address these limitations, we therefore propose a third, constructive perspective on these concepts. A constructive perspective turns transparency and accountability from analytic resources into topics of inquiry, allowing organization scholars to study how people in and around organizations put them to work and with what consequences. We introduce sites of ethical contestation as a new methodological strategy to conduct surprising and unintuitive empirical research from a constructive perspective.
Enantiomeric Differentiation of Oxygenated Bicyclo[2.2.1]heptane Derivatives by 13C NMR Spectroscopy Using Yb(hfc)3

ABSTRACT The 13C NMR behavior of 10 oxygenated compounds (ketones, alcohols, acetates) bearing the bicyclo[2.2. 1]heptane skeleton was examined in the presence of a chiral lanthanide shift reagent (Yb(hfc)3). For each compound, we measured the lanthanide-induced shift (LIS) on the signals of the carbons and the splitting of signals, enabling the enantiomeric differentiation. The enantiomeric splitting was observed for the majority of signals in the spectrum of each compound.
Thermal Properties of Plaster Reinforced with Date Palm Fibers

Abstract This study aims both to investigate the thermal properties of plaster reinforced with date palm fibers and local natural resources valorization to batter using materials construction. For that, studying the effect of addition date palm fibers on the plaster's thermal properties is a significant point. In this work, we measured effective thermal conductivity, thermal diffusivity, specific heat, and thermal effusivity of date palm fibers reinforced plaster has been studied by CT meter. Samples configurations with four lengths (10 mm - 40 mm) and four-weight ratios (0.5 % - 2 %) of palm fibers in plaster. The results obtained demonstrate that an increase in the fraction of date palm fiber engenders to a significant decrease in the thermal conductivity, thermal diffusivity, and effusivity, even an increase for the specific heat of different types of samples. Finally, this study is a contribution to the valorization of local materials in southern Algeria, and results encourage the use of plaster and date palm fibers in the field of construction and go to eco-friendly buildings.
Are CEOs’ Purchases More Profitable Than They Appear?

Abstract Little is known about why CEOs voluntarily purchase shares of their firm other than to earn direct profits. Since CEOs are risk-averse, undiversified, and face litigation costs from trading on private information, direct profits are unlikely to be the sole motive—especially since many purchases are ultimately unprofitable. We find that CEOs who have recently purchased shares are less likely to be terminated following poor performance and that this relation varies predictably with (i) their cost of purchasing shares, (ii) the profitability of their prior purchases, and (iii) their board’s access to alternative sources of information about them. We find that some CEOs voluntarily purchase shares despite the cost of foregone diversification—and, sometimes outright unprofitability—to indirectly benefit by prolonging their tenure. Our estimates imply that the average abnormal returns that CEOs earn from their purchases increases from 3% to 58% after incorporating the indirect benefit of prolonged tenure.
Post‐fire regeneration strategies in a frequently burned Cerrado community

Aim: Fire is a natural disturbance in many ecosystems throughout the world where plant populations can persist by the resprouting of individuals and/or by recruiting from seeds. We evaluated the post-fire regeneration response for 41 coexisting species, including grasses, forbs, and shrubs, from an open Cerrado community ( campo sujo ) in Central Brazil. Location:
Statistical mechanics of multilayer adsorption: electrolyte and water activities in concentrated solutions

Approximately 33 years after Stokes and Robinson's modification of the Brunauer– Emmett–Teller (BET) adsorption isotherm paved the way for experimental investigations of the water activities and properties of concentrated aqueous electrolytes, Abraham derived an equation giving the activity of a salt on the basis of the same model, but restricted his result to a binary aqueous system consisting of one salt only. Many investigators have used Stokes and Robinson's modification to show good agreement between experimental and calculated water activities even for ternary and quaternary aqueous solutions, if the system is treated as a pseudobinary. However, no previous (theoretical) attempt has been made to go beyond the single salt or pseudobinary restriction of Abraham. In this paper, we categorically prove that there is no fundamental limitation that restricts the BET model to a single electrolyte. We verify the consistency of our results through satisfaction of the Gibbs–Duhem relationships and by showing agreement between the calculated and experimental data of Iyoki on water vapor pressures for {x(2.8LiCl + LiNO3)+(1−x)H2O}, wherex=ωMw/{ωMw+ (1−ω)Ms}; ω denotes the mass fraction of lithium salts; andMwandMsdenote the molar masses of H2O and of (2.8LiCl + LiNO3), respectively. In predicting activities of the components of {x(2.8LiCl + LiNO3)+(1−x)H2O}, no experimental data on this ternary system are utilized. This fact underlies the predictive quality of the theoretical model presented in our paper. By induction, we extend our results to the case of (water + N electrolytes).
Basics and practice of surface enhanced Raman scattering (SERS) and tip enhanced Raman scattering (TERS)

This review provides an overview of the basic principles and key technical issues of surface enhanced Raman scat- tering (SERS) and tip enhanced Raman scattering (TERS). After a brief introduction to surface plasmon resonance (SPR) absorption and the basic principles behind Raman scattering and related techniques such as resonance Raman scattering and coherent anti-Stokes Raman scattering (CARS), SERS and TERS are extensively covered, including the latest progress on the fundamental understanding of the enhancement mechanism and the development of novel SERS substrates. Relevant mi- croscopy and imaging methods are also discussed, along with several examples of molecular systems studied. An attempt is also made to discuss the enhancement mechanism from both time-independent and time-dependent views of Raman scattering at the molecular level. Interesting issues related to hot spots in SERS and single molecule SERS detection are also addressed. Some perspectives on the current status and challenges for TERS are given.
Effectiveness of GeoGebra in teaching school mathematics

This article aims to explain the effectiveness of using Information and Communication Technology (ICT) in teaching and learning school mathematics. The paper is based on the results of one month experiment of Geo Gebra software in teaching and learning the concepts and problems included in the chapter commensuration of secondary level mathematics. The effectiveness of using ICT tools were explored by measuring achievement level with the help of achievement test and overall perceptions of using ICT tools through questionnaire. The data were analyzed and interpreted by using table, frequency, percentage, mean, SD and t-test. The findings revealed that there was high mean score in achievement in mathematics of experimental group (teaching with ICT) than that of control group (without using ICT), and the difference was significant at 0.05 level. Likewise, the students of experimental group had positive perception to support the use of ICT tools in teaching and learning mathematics. Thus, the use of ICT, particularly Geo Gebra is an effective tool to increase achievement; to promote curiosity, creativity; to make clear sense of concepts; and to encourage overall learning of students in mathematics. Finally, the study suggests that school mathematics teachers need to use ICT for effective teaching and learning.
Doping Effects of SiO2 on the Dielectric and Piezoelectric Properties of PbTiO3-Based Ceramics and Its SAW Applications

ABSTRACT The Sm-modified lead titanate ceramics with a composition of (Pb0.85Sm0.1)- (Ti0.98Mn0.02)O3 piezoceramics doped with SiO2 were prepared by conventional mixed-oxide method using sintering temperature at 1100°C. Microstructural and compositional analyses of the PbTiO3-based ceramics have been carried out using XRD and SEM. The effects of dopants on the sintering temperature and piezoelectric properties of the ceramics have been investigated. We successfully showed that these additives were helpful in lowering of the sintering temperature and still keep high thickness electromechanical coupling coefficient, kt, and small planar electromechanical coupling coefficient, kp. Surface acoustic wave (SAW) devices were fabricated and the properties, including phase velocity and temperature coefficient of frequency (TCF), were measured.
Comparison of Waste Management between Indonesia and South Korea

The waste management system in Indonesia still faces many challenges while the waste management system in South Korea is systematic and effective. Therefore, further analysis of waste management in Indonesia and its comparison with South Korea is necessary to be researched. The purpose of this article is to determine the waste management differences in Indonesia and South Korea. This research was made by using data samples such as Putri Cempo Open Dumping, Indonesia and Sudokwon Sanitary Landfill, South Korea. Data were obtained by study visits and the form of qualitative data. Waste management is an important thing to study. Waste management in Indonesia is still at a low level because it only uses an open dumping system. Meanwhile, waste management in South Korea has used a sanitary landfill system. Another difference is Indonesia has not implemented sustainable waste sorting, but South Korea has implemented sustainable, structural, and effective waste sorting. From this study, it was found that municipal waste management in Indonesia has proven to be less than optimal compared to municipal waste management in South Korea.
Discriminant analysis using fatty acids profile, stable carbon isotopes and tocopherols content as tool for feeding system prediction in Iberian pigs

Aim of study: The application of three analytical methods (fatty acids: FA, tocopherols: TOC, and isotope ratio: ISO) to distinguish the feeding type received by Iberian pigs during the fattening stage.Area of study: This distinction is very important for the labelling of Iberian high-quality products in the Quercus forest located on the southwest of Iberian Peninsula, where several production systems coexist.Material and methods: Discriminant analysis on fat samples with unknown background obtained from commercial pigs was applied. The feasibility of the combination method to determine the authentication of feeding background was studied on samples from different fattening system: free-range feeding with acorn and pastures (BE); free-range feeding acorn and pastures plus commercial feeds (RE); open-air feeding with commercial feeds (CA); standard feeding with commercial feeds (CE). Main results: In a first application of the methods, the overall success rate was 60.1% for FA, 49.7% for ISO and 49.3% for TOC. When some of the batches were reclassified attending to those previous results and additional information available about farm characteristics, ISO and TOC analyses had a 70% of success rate in the four categories, whereas FA showed 40.5%, attributable to the use of high-oleic commercial diets. The predictions improved with the method combination. The ISO+TOC combination achieved a 84.1% of success in prediction. When it was reduced to just two categories (acorn vs non-acorn), the success reached a 95% for FA+TOC and ISO+TOC.Research highlights: The use of these methods as a complementary tool for quality controls is highly recommended to avoid undesirable misclassifications.
Investment in Technology: Does It Proliferate the Profitability and Performance of the Indian Banks?

This study gauges the profitability and performance of Indian commercial banks under the technology advancements. In this study, the authors identified three domains that give advantage to banks due to technology incorporation, that is, increased sales revenue, reduced operating expenses, and increased employee productivity. The authors assess the effect of these domains on banks’ profitability and performance. This study is conducted for the period between the years 2003 and 2018 across 34 public and private banks for empirical analysis. The authors examined the impact of investment in technology on the profitability using panel data analysis and evaluated the long-term effect of technology investment using the vector error correction model. This study found that there is a mixed effect of technology spend on the profitability and performance of Indian banks, where private sector banks are more aggressive in technology investment as compared to the public sector banks. This study recommends an optimal technology-related strategy to gain improved productivity for the banking business, that is, planned technology reserves, customer awareness campaigns about technology-enabled products, and robust employee–customer motivation policy.
State Machine Approach for Lane Changing Driving Behavior Recognition

Research in understanding human behavior is a growing field within the development of Advanced Driving Assistance Systems (ADASs). In this contribution, a state machine approach is proposed to develop a driving behavior recognition model. The state machine approach is a behavior model based on the current state and a given set of inputs. Transitions to different states occur or we remain in the same state producing outputs. The transition between states depends on a set of environmental and driving variables. Based on a heuristic understanding of driving situations modeled as states, as well as one of the related actions modeling the state, using an assumed relation between them as the state machine topology, in this paper, a crisp approach is applied to adapt the model to real behaviors. An important aspect of the contribution is to introduce a trainable state machine-based model to describe drivers’ lane changing behavior. Three driving maneuvers are defined as states. The training of the model is related to the definition/tuning of transition variables (and state definitions). Here, driving data are used as the input for training. The non-dominated sorting genetic algorithm II is used to generate the optimized transition threshold. Comparing the data of actual human driving behaviors collected using driving simulator experiments and the calculated driving behaviors, this approach is able to develop a personalized behavior recognition model. The newly established algorithm presents an easy to apply, reliable, and interpretable AI approach.
Beyond the protein concept: health aspects of using edible insects on animals

There is an increasing interest in the use of insects in animal feed since they contain high proteins levels, lipids, vitamins and minerals. In particular, insect-derived proteins are seen as one of the potential solution to face the increasing protein shortage and are able to fully substitute soybean meal or fishmeal in aquaculture or livestock feeds. However, beside their interesting nutritional composition, insects are also rich in bioactive compounds such as chitin, antimicrobial peptides or specific fatty acids with immunostimulating, antimicrobial and/or anti-inflammatory properties able to sustain animal health, increase their resistance to diseases. Further studies will also have to investigate whether insects share similarities with bacterial or parasitical pathogens and may act as immunostimulants. These recent findings may launch insects beyond the protein concept into healthy animal feeds. This review presents the effects of insects and their bioactive compounds on fish and crustaceans, poultry, pigs and rabbits immune system, gut health, microbiota and resistance to diseases.
INTERNAL FACTORS THAT STIMULATE THE INTERNATIONALIZATION OF COMPANIES IN PERU’S JEWELLERY SECTOR

The purpose of this research is to make known the internal factors that stimulate the internationalization of companies in the jewelery sector. We consider the qualitative approach at the descriptive level through semi-structured interviews with twelve major exporting companies in the jewelery sector in Peru. The results of the investigation show that the most relevant internal factors for the internationalization of jewelry companies is the international experience based on the understanding of markets, foreign clients, competition, knowledge of the documents and certificates necessary for an export, international commercial relations and risks in the negotiations; Another relevant internal factor is the personalization of the product with characteristics of innovation that generates better export results and, therefore, have a competitive position, since in the international market customers consider that companies have a product with added value, innovative and competitive. Moderately relevant factors are transaction costs, firm size, and the tacit nature of know-how; while opportunistic behaviuor is of little relevance. These findings will serve to understand opportunities and limitations that companies must be aware of to undertake new internationalization projects in the jewelery sector.
Physical Activity in the Workplace – Making the Healthy Choice the Easy Choice

Background: Engaging in physical activity in the workplace is important to address to combat the negative health outcomes associated with physical inactivity and prolonged sitting. Aim: This study aims to identify efforts that increase light neuromotor physical activity in university workplaces for sedentary employees. Methods: Sub-study 1 examined 15 intervention employees and 10 control employees. MANOVA was used to examine average number of days employees did three movements at work between groups over an eight-week period. Sub-study 2 examined 56 employees and measured three beliefs towards employee intention to do the movements at work. A linear regression examined the significance of the beliefs in predicting employee intention. Results: MANOVA results showed a significant effect between groups on the average number of days employees did three movements over an eight-week period of time, F (3, 21) = 3.16; p < . 05. The adjusted R-squared predicting intention from the three beliefs was . 343 (p < .001). Participants’ belief in how ‘easy’ doing the movements would be significantly predicted intention scores (β= .467; p < .001) as did the ‘popular’ belief (β = .371; p < .01). Conclusion: Worksite group physical activity programs can increase the frequency employees get up and move at work. Employee beliefs of how easy or popular a behavior is can significantly predict intention to do neuromotor movements in workplaces. Submitted 19 February 2020: accepted 28 June 2020
