Characteristic of the wear of a tool coating based on amorphous carbon during chipboard milling

Characteristic of the wear of a tool coating based on amorphous carbon during chipboard milling. The study verified the durability and the course of wear during the durability tests of the TiAlN / a-C:N double tool coating. The aforementioned coating consisted of a bottom layer of TiAlN and a top layer based on nitrogenenriched amorphous carbon. Standard replaceable cutters for milling heads made of WC-Co sintered carbide were subjected to the modification process. The coating was applied using plasma by RF Magnetron Sputtering. During the tests, the blade wear was measured using a workshop microscope. The VB max indicator measured on the clearance face was adopted as the blunting criterion and its maximum value was set on 0,2 mm. The results show that the additional coating of amorphous carbon contributed to the increase of the tool durability determined with cutting distance. The use of only a single layer based on TiAlN shortened the durability by about 3%. On the other hand, applying both the bottom and top layers (TiAlN /a-C:N) extended the cutting distance by about 24%. The research showed a clear advantage in terms of the durability of the blades modified with a multi-layer coating in relation to a single-layer. Moreover, the positive effect of the top layer containing amorphous carbon on tool durability has been demonstrated.
Mealtime Behaviour Problems and its Association with Behavioural Problems in Preschool and Elementary Children with Autism Spectrum Disorder (ASD)

Mealtime behaviour problems are one of the most prominent concerns associated with autism spectrum disorder (ASD) in children. Few researchers have described mealtime behaviours and feeding issues, and their relationship with the diagnosis of ASD, its symptoms, and the surrounding environment has rarely been examined. Objective: To explore Saudi parental reports of common mealtime behaviour problems in children with ASD with the help of an established tool for measuring mealtime behaviour problems in children with ASD. Method: This study was a descriptive cross-sectional study that utilized the Brief Autism Mealtime Behaviour Inventory (BAMBI) and the Strengths and Difficulties questionnaire (SDQ) to collect data. Results: The study included 57 parents of children with ASD aged 4–12 years. The findings revealed that children with ASD in The Kingdom of Saudi Arabia (KSA) do not generally display excessive behaviour problems, and there is no significant association between mealtime behaviour problems and general behaviour problems in children with autism in KSA. Conclusion: Feeding behavioural problems do exist in children with ASD. Understanding these behaviours could be the first step to designing suitable interventions to inform and educate children and their parents about healthier mealtime habits which could decrease parental distress.
Impact of COVID-19 on Teaching and Classroom Management: Thoughts Based on Current Situation and the Role of Communication

The present article focuses on the impact that COVID-19 has on teaching and school classroom management that affect the whole school management as well. As the teaching circumstances are compulsory and dramatically changing and as face-to-face teaching is altering into distance teaching (e-teaching), the teaching features are deeply modified either it takes place in home or in school environment harming communication quality due to physical presence deprivation. Within this framework, present chapter aims at the presentation of teaching procedure developmental progress under the light of a historical overview upon this subject. Also, it aims at the presentation of distance learning as a modern teaching form which has intruded in traditional education reality by the emerged necessity related to entire population's protection against COVID-19 pandemic. Nevertheless, as it seems by the evolution of the facts, COVID-19 pandemic was simply speeding the introduction of distance learning into educational system which, more or less, was constituted a central choice for many states and governments. Furthermore, in this chapter a discussion takes place related to teachers’, students’; and parents’ reactions about the implementation of distant teaching. This discussion claims that the initial interest for distant teaching, had within few months converted into a boring and undesirable reality from which most involved persons wanted to be released as soon as possible. The chapter is completed with a reference to the purpose of educational community members and all educators in achieving their return into school's normality, namely in procedures and situations that were existed before COVID-19's pandemic advent.
HIGH ANION GAP METABOLIC ACIDOSIS IN SEVERE DELIBERATE POISONING WITH METFORMIN – SUCCESSFUL TREATMENT WITH 2.5-HOUR CONVENTIONAL HEMODYALISIS

Metformin-associated lactic acidosis is a rare, life-threatening condition with a high mortality rate, that could occur both with therapeutic use and in metformin overdose. Clinical manifestations may be nonspecific, with severe anion gap metabolic acidosis and elevated lactate levels being the most prominent laboratory findings; hence, delaying the diagnosis and treatment. Renal replacement therapy plays a key role in the treatment of severe metformin poisoning. We herewith present a case with intentional metformin poisoning successfully treated with one session of hemodialysis in combination with parenteral sodium bicarbonate therapy. A 17-year-old non-diabetic woman ingested 25 grams of metformin in a suicide attempt. She developed vomiting and diarrhoea and was brought to the local emergency unit, and shortly after admittance she became nonresponsive. Glasgow coma scale was 7/15 (E2, V1, M4), glucose level was 3.4 mmol/L and blood pressure was 90/60 mmHg. The first arterial blood gas analysis demonstrated a severe metabolic acidosis with high lactate level (pH = 6.778, BE -31.7, lactate 18 mmol/L, anion gap 39.8 mmol/L), and, subsequently, she developed a non-oliguric renal failure. Lactic acidosis was successfully treated with a combination of a conventional 2.5-hour bicarbonate HD and early administration of intravenous bicarbonate. The arterial pH steadily increased back to normal levels, lactic acidosis improved and kidney function recovered completely. It could be concluded that even a single session of timely applied conventional HD in combination with parenteral administration of bicarbonates allows simultaneous drug removal, lactate reduction and acid-base correction and should be a treatment of choice in hemodynamically stable patients with severe metformin poisoning.
Generalization of Cross-Entropy Loss Function for Image Classification

Classification task is one of the most common tasks in machine learning. This supervised learning problem consists in assigning each input to one of a finite number of discrete categories. Classification task appears naturally in numerous applications, such as medical image processing, speech recognition, maintenance systems, accident detection, autonomous driving etc.In the last decade methods of deep learning have proven to be extremely efficient in multiple machine learning problems, including classification. Whereas the neural network architecture might depend a lot on data type and restrictions posed by the nature of the problem (for example, real-time applications), the process of its training (i.e. finding model’s parameters) is almost always presented as loss function optimization problem.Cross-entropy is a loss function often used for multiclass classification problems, as it allows to achieve high accuracy results.Here we propose to use a generalized version of this loss based on Renyi divergence and entropy. We remark that in case of binary labels proposed generalization is reduced to cross-entropy, thus we work in the context of soft labels. Specifically, we consider a problem of image classification being solved by application of convolution neural networks with mixup regularizer. The latter expands the training set by taking convex combination of pairs of data samples and corresponding labels. Consequently, labels are no longer binary (corresponding to single class), but have a form of vector of probabilities. In such settings cross-entropy and proposed generalization with Renyi divergence and entropy are distinct, and their comparison makes sense.To measure effectiveness of the proposed loss function we consider image classification problem on benchmark CIFAR-10 dataset. This dataset consists of 60000 images belonging to 10 classes, where images are color and have the size of 32×32. Training set consists of 50000 images, and the test set contains 10000 images.For the convolution neural network, we follow [1] where the same classification task was studied with respect to different loss functions and consider the same neural network architecture in order to obtain comparable results.Experiments demonstrate superiority of the proposed method over cross-entropy for loss function parameter value α < 1. For parameter value α > 1 proposed method shows worse results than cross-entropy loss function. Finally, parameter value α = 1 corresponds to cross-entropy.
Professional networking: Exploring differences between offline and online networking

Professional networking has mostly been researched in offline contexts. With professional social networking sites (SNS), such as LinkedIn or the German platform XING, professional networking can be extended to online contexts. Therefore, this study examines if people differ in the intensity of offline and online networking and if influence factors differentially predict offline and online networking. An exploratory online survey of working people (N = 326, M age = 37 years, 56% women) revealed that mean values among the four different networking types did not differ significantly. However, people can be divided into four clusters of networkers (the minimal, the heavy, the mainly offline, and the mainly online networkers). When looking at influence factors, there is a positive association of people’s knowing about the benefits of networking and their networking intensity for all types of networking offline and online. Beyond that, the negative affective influence of anxiety towards unknown people on networking shows an interaction effect with networking type as it is stronger for offline networking than it is for online networking. The results indicate that professional social networking sites might help people with their networking pursuits by reducing negative emotions associated with networking, thereby contributing to a social compensation effect.
The Effect of a Face-To-Face ScienceReady Preparatory Short Course on University Students’ Self-Efficacy

The ScienceReady preparatory course is an intensive study designed to improve beginning university undergraduate students’ understanding of medical/scientific concepts, and reduce their anxiety about studying the science component of their enrolled programs. Its goals are to stimulate students’ science curiosity and provide the fundamental scientific content they are expected to know and build further on the knowledge that will feature in their upcoming programs. This article aims to describe the ScienceReady course, discuss the impact of the course on the participants, determine the relationship of the course with self-efficacy, and explain the implications of the results. Students were tested before and after the course to ascertain whether it increased or decreased or not affected self-efficacy. The results of the pre- and post-test surveys were unequivocal. The majority of the individual items for the self-efficacy questionnaire showed a significant increase in self-efficacy post-course.
English-Myanmar (Burmese) Phrase-Based SMT with One-to-One and One-to-Multiple Translations Corpora

This paper contributes the first investigation of machine translation (MT) performance differences between Myanmar and English languages with the use of several possible Myanmar translations for the specific primary educational domain. We also developed both one-to-one and many Myanmar translations corpora (over 8K and 46K sentences) based on old and new English textbooks (including Grade 1 to 3) which are published by the Ministry of Education. Our developing parallel corpora were used for phrase-based statistical machine translation (PBSMT) which is the de facto standard of statistical machine translation. We measured machine translation performance differences among one-to-many English to Myanmar translation corpora. The differences range between 19.68 and 52.38 BLEU scores from English to Myanmar and between 50.17 and 75.12 BLEU scores from Myanmar to English translation. We expect this study can be applied in Myanmar-to-English automatic speech recognition (ASR) development for primary English textbooks. The main purpose is to translate primary English textbooks data correctly even if the children use in several Myanmar conversation styles.
Prevalence of trypanosomosis and associated haematological changes among hunting dogs in Abeokuta, Nigeria

African animal trypanosomosis (AAT) is one of the major constraints to the development of effective livestock production systems. Dogs are human companion and are believed to be sentinels for infection with the human species. This study was to detect subclinical and clinical infection of trypanosomes among hunting dogs in Abeokuta and its environs using molecular technique. A total of 87 dogs comprising of 49 males and 38 females were ramdomly screened for trypanosomes by polymerase chain reaction technique. Among 87 dogs screened, 17.2% were positive for Trypanosoma congolense and Trypanosoma brucei. Prevalence of trypanosomosis in males was 14.3% while the females accounted for 21.1%. Hematological examination revealed a significant increase (p < 0.05) in mean white blood cells (20.9 ± 2.11) and monocyte counts (5.9 ± 0.62) of the infected dogs compared to uninfected dogs. Packed Cell Volume (36.0 ± 3.73) and haemoglobin concentration (13.9 ± 2.10) decreased insignificantly, while, red blood cells (7.1 ± 0.87), lymphocyte (60.9 ± 9.63), neutrophil (33.3 ± 9.16) and eosinophil (1.4 ± 0.42) counts increased insignificantly (p > 0.05) in infected dogs compared to uninfected dogs. In conclusion, caninine trypanosomosis is prevalent in hunting dogs, in Abeokuta.
Mental Simulations of Phonological Representations Are Causally Linked to Silent Reading of Direct Versus Indirect Speech

Embodied theories propose that language is understood via mental simulations of sensory states related to perception and action. Given that direct speech (e.g., She says, “It’s a lovely day! ”) is perceived to be more vivid than indirect speech (e.g., She says (that) it’s a lovely day) in perception, recent research shows in silent reading that more vivid speech representations are mentally simulated for direct speech than for indirect speech. This ‘simulated’ speech is found to contain suprasegmental prosodic representations (e.g., speech prosody) but its phonological detail and its causal role in silent reading of direct speech remain unclear. Here in three experiments, I explored the phonological aspect and the causal role of speech simulations in silent reading of tongue twisters in direct speech, indirect speech and non-speech sentences. The results demonstrated greater visual tongue-twister effects (phonemic interference) during silent reading (Experiment 1) but not oral reading (Experiment 2) of direct speech as compared to indirect speech and non-speech. The tongue-twister effects in silent reading of direct speech were selectively disrupted by phonological interference (concurrent articulation) as compared to manual interference (finger tapping) (Experiment 3). The results replicated more vivid speech simulations in silent reading of direct speech, and additionally extended them to the phonological dimension. Crucially, they demonstrated a causal role of phonological simulations in silent reading of direct speech, at least in tongue-twister reading. The findings are discussed in relation to multidimensionality and task dependence of mental simulation and its mechanisms. BO YAO
Job satisfaction and job commitment of Greek tennis, table-tennis and badminton coaches

The aim of the study was to investigate job satisfaction and job commitment of coaches of the three major racket sports in Greek tennis, table-tennis and badminton. One hundred and ten (N = 110) tennis (NT= 61), table-tennis (NTT = 31) and badminton (NB = 18) coaches responded to the Coach Satisfaction Questionnaire (CSQ), an eleven-factor instrument which assesses coaches’ job satisfaction and to the Occupational-Organizational Commitment Scale, a six factor questionnaire which evaluates the different forms of occupational and organizational commitment. Forty six of the coaches were full-time (NFT = 46) whereas of the rest, sixty four were part-time (NPT = 64). The results of a series of t-tests, ANOVAs and correlation analyses revealed various significant differences and relationships. Some of the most important are that: a) tennis coaches and full-time coaches were more satisfied in most of the job satisfaction dimensions, b) significant correlations were noticed between “job satisfaction” and “organizational commitment” variables, c) “autonomy”, was a predictor of “organizational affective commitment”, d) “satisfaction with coaching job” was the unique predictor of occupational affective and “occupational normative commitment” and e) “team performance” was the only predictor of “occupational continuance commitment”. Most of the results are in accordance with the existing job satisfaction literature however, further research is needed on human relation practices of National Federations and/or sport clubs associated with them, in order to have a better understanding of how certain practices and policies lead to higher levels of job satisfaction, organizational and occupational commitment among racket sport coaches.

Empirical evidence of profitability anomaly in the Thai stock market

This study presents empirical evidence of profitability anomaly in the Stock Exchange of Thailand. The effects of gross profitability, operating profitability, and cash flow-to-price (C/P) on the subsequent stock returns are examined using the data from 2002 to 2019. The results of Fama-Macbeth (1973) regression and Carhart (1997) four-factor model indicate that gross profitability and C/P have significant explanatory power for future returns but not operating profitability. Further analysis confirms that gross profitability-sorted portfolio generates the largest risk-adjusted return and C/P-sorted portfolio presents the best consistency to outperform the market. Investing in the portfolios consisted of stocks with high gross profitability and C/P provides protection from the market downside.
Assessing predictors that influence working mothers’ perception of child care service quality: A SERVQUAL Analysis

This study examines working mothers’ perceptions towards service quality on childcare centres in Dar es Salaam. The study applied five dimensions in SERVQUAL as indicators that influence working mothers’ perceptions. The study used service quality SERVQUAL collected data from 411 working mothers with children aged 2-5 years using structured questionnaires. Data collected were analyzed using PLS-SEM. Findings revealed a significant and positive relationship between service quality dimensions and childcare service quality. It was also shown that tangibility, responsiveness, empathy, assurance, and reliability directly influence service quality, even when the effects of all constructs are considered simultaneously. The study recommends child care centres to conduct service quality surveys among its care givers and parents and consider their opinions in order to identify areas for service quality improvements. Besides, Ministry of Community Development, Gender, and Children need to harmonize childcare services standard guidelines to incorporate working mother’s views since they are directly setting instructive objectives.
The diagnostic value of AFP, AFP L3 and PIVKA II in hepatocellular carcinoma outcome of cirrhosis of the liver HBV and HCV etiology

Hepatocellular carcinoma (HCC) is the third largest cause of death among all cancer cases in the world.Moreover, in most cases, it develops against the background of viral hepatitis of the liver. I should be noted, and the fact that the detection of the later stages of the forecast it usually unfavorable.This study focuses on AFP, AFP L 3, and PIVKA II as oncological markers of HCC in patients with chronic viral hepatitis. It was found that the use of the combination of PIVKA II and AFP increases the sensitivity by 16.6% compared with the use of AFP alone, which is comparable with the results of all three-tumor markers.
Biology and foraging behaviour of Oenopiakirbyi Mulsant (Coleoptera: Coccinellidae) on melon aphid, Aphis gossypii Glover

Oenopia kirbyi Mulsant is an important naturally occurring predator of Aphis gossypii Glover in cucumber. Before recommending the natural enemy against any pest it is important to investigate the feeding efficiency and density responsiveness of the given natural enemy. We, therefore, studied the biology and predatory potential of O. kirbyi against this aphid in the laboratory at 25 ± 0.5 °C, 70 ± 5% RH and 12L: 12D photoperiod. Incubation, total larval, pre pupal and pupal period of O. kirbyi was 3.40, 15.26, 1.30 and 4.80 days, respectively. Females on an average laid 177.60 ± 6.38 eggs. Pre oviposition, oviposition and post oviposition period of O. kirbyi was 6.92, 23.22 and 5.48 days, respectively. Adult female and adult male consumed an average of 2634.78 and 2012.52 aphids in their life span of 38.50 and 31.38 days, respectively, whereas, total prey consumption during the larval stages was 535.90 aphids/ predator. All the predator stages exhibited a type II functional response to the aphid. Based on Rogers’s random predator equation, the attack rate was lowest (0.065) in the first-instar and highest (0.171) in the adult stage. Handling times of the adult and the fourth-instar stages (0.237 and 0.263 h, respectively) were much shorter than other stages. Study indicates that the adults and the fourth-instar grubs were the most voracious stages and could be considered for the biological control of the aphid after field evaluation.
Assessment of Municipal Solid Waste Clay Liner System Using Consolidation Test

The present study has been carried out to provide landfill clay liner soil with admixture microsilica in different proportions. The geoenvironmental and physico-chemical characteristics were carried out to characterize the clay mixed with definite portion of microsilica in mass ratio. An experimental investigation was performed to determine the effect of clay and microsilica consolidation of leachate. The microsilicaclay composites were mixed in ratios of 0:100, 1:10 and 1:20 and experiment carried out with leachate as the permeation liquid. The quantitative reductions in coefficient of permeability increase in the effective stress for the all ratios. The chemical reaction of water and soil are lower than that in the leachate. In real field the leachate as permeation liquid after construction of liners, is retained by adding microsilica in clay liner system. 1:10 ratio of microsilica-clay composites was found to be more suitable municipal solid waste leachate as permeating liquid.
