Direct method of studying heat exchange in multilayered bodies of basic geometric forms with imperfect heat contact

purpose. Characteristics of heat transfer processes in multilayer bodies of basic geometric shapes simultaneously under condi­ tions of convective heat transfer on its surfaces and taking into account imperfect thermal contact between the layers. Methodology. A direct method was applied to solve a one­parameter family of boundary value problems in the theory of heat conduction. This method is based on the reduction method, the concept of quasiderivatives, a system of differential equations with impulse action, the method of separation of variables, and the modified method of eigenfunctions of Fourier. It is worth noting that the application of the concept of quasiderivatives allows you to circumvent the well­known problem of multiplication of gen­ eralized functions, which arises when using the differentiation procedure of the coefficients of a differential equation. Such a pro­ cedure, in our opinion, casts doubt on the equivalence of the transition to the differential equation obtained in this way with gen­ eralized coefficients. findings. The solution to the problem is obtained in a closed form. The proposed algorithm does not contain a solution to volume conjugation problems. It includes only: a) finding the roots of the corresponding characteristic equations; b) the multipli­ cation of a finite number of known (2 × 2) matrices; c) the calculation of certain integrals; d) summing the required number of members of the series to obtain the specified accuracy. As an illustration, we consider model examples of heating eight­layer struc­ tures in a fire. Originality. For the first time, the direct method has been applied to solving the problem of the distribution of an unsteady temperature field over the thickness of multilayer structures of basic geometric shapes simultaneously, in the presence of imperfect thermal contact between the layers. practical value. The implementation of the research results allows us to effectively study the heat transfer processes in multi­ layer structures, which are found in a number of applied problems.
Relationship between Photographs on Sports Newspapers and Patronage among Residents of Lagos State

In recent times, many sports-only newspapers have started circulating in the country. One of the major features of virtually all the sports newspapers is the generous use of photographs, especially on the front pages. This article examined the relationship between the use of photographs and patronage of sports newspapers. Survey design was adopted to gather data among respondents of two purposively selected Local Government Areas in Lagos State. Findings showed that the influence of photographs on the patronage of sports newspapers is significantly positive among men than women. Findings further revealed that majority of the respondents are attracted to buy sports newspapers because of the display of captivating photographs on the cover page. Based on the findings, the researchers concluded that photographs are indispensable catalyst for the sale of sports newspapers and that for sports newspapers to be popular among women, publishers must include stories and pictures of sports involving women. The study therefore recommended that publishers of sports newspapers should introduce female-friendly sports stories, along with pictures, to create interest for sports newspapers among women. Also, the use of active yet timely photographs and well captioned pictures should be encouraged on all pages of the publications.
Effect Of Preheating On The Hardness And Microstructure In Shielded Metal Arc Weldments Of A283 B

The purpose of this study was to determine the effect of heating on the welding process of SMAW (Shielded Metal Arc Welding) in terms of hardness and microstructure of welded metal. Much welding has been done by preheating but below the temperature used below the initial martensitic temperature which reaches 452 ° C, this data is sourced from research by S.Zheng et.al and Y. Huang et.al. For this reason, an experiment was carried out with heat temperatures above a martensitic temperature of 500 ° C. The results show that in the Weld Metal area the pearlite structure appears larger, the effect of current strength on HAZ width is directly proportional, the greater the current strength, the wider HAZ, and hardness are affected by the rough grains of martensite KeywordsMicrostructure, HAZ Width, Hardness, Preheat, Pearlite, Ferrite
Debiasing Concept-based Explanations with Causal Analysis

Concept-based explanation approach is a popular model interpertability tool because it expresses the reasons for a model's predictions in terms of concepts that are meaningful for the domain experts. In this work, we study the problem of the concepts being correlated with confounding information in the features. We propose a new causal prior graph for modeling the impacts of unobserved variables and a method to remove the impact of confounding information and noise using a two-stage regression technique borrowed from the instrumental variable literature. We also model the completeness of the concepts set and show that our debiasing method works when the concepts are not complete. Our synthetic and real-world experiments demonstrate the success of our method in removing biases and improving the ranking of the concepts in terms of their contribution to the explanation of the predictions.
Versatile function in GPA

: The paper, devoted to continuous versatile function application in the Genetic Programming Algorithm (GPA), begins with a discussion of similarities between GPA with versatile function and neural network. Then, the function set inﬂuence on GPA eﬃciency is discussed. In the next part, there is described a hybrid evolutionary algorithm that combines GPA for structure development and Evolutionary Strategy (ES) for parameters and constant optimization; which is herein much more signiﬁcant than in the standard GPA. There is also discussed the setting of parameters of this hybrid algorithm and due to a diﬀerent function set. The original idea of a versatile function, which origins come from the area of fuzzy control systems, is formulated and explained. Four diﬀerent implementations of this versatile function are discussed. On the base of experiments with the hybrid evolutionary algorithm providing symbolic regression of precomputed Lorenz attractor system data representing its dynamic behaviour; the comparison of three variants of versatile functions was formulated. The paper also presents ways how to set up hybrid evolutionary algorithm parameters like population sizes as well as limits of maximal population numbers for both algorithms: GPA for structural development and nested ES for parameters optimization. The versatile function concept is applicable but it requires the hybrid evolutionary algorithm use as it is explained in the paper.

The main objective of this study determines the efficacy of several biological and chemical controls on the growth and productivity of green bean crop and the management of white rot disease caused by Sclerotiniasclerotiorum. Five biological control treatments,namely Trichodermaasperellum(85 g/100L-1), Bacillus megaterium(250 g/100L-1), Trichoderma album (250 g/100L-1), Chitosan (200 g/100L-1), and Hydrogen peroxidase (250 g/100L-1) were applied and compared with three fungicides, namely Flutolanil (100 g/100L-1), Tebuconazole with Fluopyram (50 ml/100L-1) and Tebuconazole (188 ml/100L-1 ) as well as control treatment for their ability in increasing green bean crop productivity and reducing disease severity and incidence growth of white rot by spraying two times on plants; at 35-45 days after emergence or 59-61 BBCH stages (BiologischeBundesanstalt, Bundessortenamt und CHemischeIndustrie) using knapsack sprayer at 300 L. /Feddan. Results indicated that Tebuconazole with Fluopyram applications significantly gave the highest indications of total and marketable yield compared with the other experimental treatments in both seasons. Moreover, the two times of spraying by Tebuconazole with Fluopyram, and Hydrogen peroxidase treatments had significantly lowered disease incidence and disease severity and increasing control efficiency in both seasons. Furthermore, other treatments like T. asperellum, Tebuconazole or Flutolanil had a moderate efficacy on green bean crop productivity, disease severity and incidence of white rot compared to the control treatment. Finally, the control treatment was the lowest values of crop productivity and disease efficacy.
Associative processes in addiction relapse models: A review of their Pavlovian and instrumental mechanisms, history, and terminology

Animal models of relapse to drug-seeking have borrowed heavily from associative learning approaches. In studies of relapse-like behaviour, animals learn to self-administer drugs then receive a period of extinction during which they learn to inhibit the operant response. Several triggers can produce a recovery of responding which form the basis of a variety of models. These include the passage of time (spontaneous recovery), drug availability (rapid reacquisition), extinction of an alternative response (resurgence), context change (renewal), drug priming, stress, and cues (reinstatement). In most cases, the behavioural processes driving extinction and recovery in operant drug self-administration studies are similar to those in the Pavlovian and behavioural literature, such as context effects. However, reinstatement in addiction studies have several differences with Pavlovian reinstatement, which have emerged over several decades, in experimental procedures, associative mechanisms, and terminology. Interestingly, in cue-induced reinstatement, drug-paired cues that are present during acquisition are omitted during lever extinction. The unextinguished drug-paired cue may limit the model’s translational relevance to cue exposure therapy and renders its underlying associative mechanisms ambiguous. We review major behavioural theories that explain recovery phenomena, with a particular focus on cue-induced reinstatement because it is a widely used model in addiction. We argue that cue-induced reinstatement may be explained by a combination of behavioural processes, including reacquisition of conditioned reinforcement and Pavlovian to Instrumental Transfer. While there are important differences between addiction studies and the behavioural literature in terminology and procedures, it is clear that understanding associative learning processes is essential for studying relapse.
SELECTION OF ONCOPLASTIC SURGERY IN UZBEKISTAN REGION BREAST CANCER PATIENTS

Breast cancer is a common disease affecting millions of women, often at a relatively young age. Every tenth woman in the Uzbekistan develop breast cancer during her lifetime; 2.5 million women survive annually after treatment, and a significant increase in the number of such patients is expected in the coming decades.1 Reconstruction after a mastectomy enables women to alleviate the emotional and aesthetic defect of this severe illness. Successful breast surgery virtually eliminates a postmastectomy psychosocial defect this is the main disabling factor. Oncoplastic surgery is increasingly performed in Uzbekish women;Uzbekish women usually have normal-big to moderate-sized breasts. To achieve better outcomes in reconstructed breasts, several factors determining the optimal surgical method should be considered. Methods: A total of 135 patients who underwent oncoplastic surgery from September 2015 to November 2019were retrospectively investigated. We used various methods, including glandular tissue reshaping, latissimus dorsi (LD) flap transposition, and reduction oncoplasty to restore the breast volume and symmetry. Results: The mean weight of the tumor specimen was 40.46 g and tumor specimen to breast volume ratio was 0.12 g/cc in the glandular tissue reshaping group (n=59), 101.47 g and 0.14 g/cc in the reduction oncoplasty group (n=17), and 82.54 g and 0.20 g/cc in the LD flap Central Asian Journal of Medicine Central Asian Journal of Medicine uzjournals.edu. uz/tma 57 2020#4 group (n=44). Glandular tissue reshaping was mostly performed in the upper outer quadrant and LD flap transposition in the lower inner quadrant. No major complications were noted. Most patients were satisfied with the aesthetic results. Conclusion: We had satisfactory outcomes of oncoplastic surgeries in Uzbekish patients. The results about specimen weight and tumor to breast ratio of Uzbekistan region patients will be a helpful reference to determine the method of oncoplastic surgery.
Chinese Language Learners’ Participation in a WeChat Online Community of Practice (中文学习者在微信实践社区中的参与度)

Utilizing WeChat in Chinese language education has generated interest among Chinese language educators and researchers. Both its affordances and constraints have been documented in previous studies. However, discussion about how language learners participate in WeChatsupported activities remains scarce. This qualitative literature review analyzed relevant studies through the theoretical lens of Community of Practice (Wenger, 1998), focusing on the core construct—participation. The results show that current common practices have not fully tapped into the educational potential of WeChat to allow learners to fully participate. Different ways of using WeChat for educational purposes should be pedagogically sound and could be further explored. Additionally, participants’ transition towards full participation is not necessarily associated with language proficiency. Instead, three factors—affective, social and curricular—exert influence collectively. 摘要: 近年来,中文教师以及学者针对微信在中文教学中的运用进行 了尝试以及研究。 然而,中文学习者在微信交际活动中参与度如何? 相关讨论并不多。 本篇质性论文综述采用实践社区理论,梳理、分析 了近年来有关学术文章,指出:目前中文教学中运用到的微信功能有 限,学习者在各类活动中参与度不等。 微信相关教学活动应该在教学 理念的指导下合理设计。 此外,语言水平并不一定会影响中文学习者 在微信交际活动中的参与度。 情感因素、社交因素以及课程设计都会
Impact of increasing atmospheric CO2 concentration on growth characteristics and yield in maize and rice

To assess the effect of increasing atmospheric CO2 concentration ([CO2]) on growth and yield in maize and rice, an experiment was carried out in open top chambers (OTCs) at different atmospheric CO2 concentration treatments (550 ? mol/mol, T1; 750 ? mol/mol, T2 and a control, CK) in Nanjing, Jiangsu, China. Our results indicated that the plant height, leaf area index (LAI), Soil and Plant Analyzer Development (SPAD) and net photosynthesis (NPn) of the maize (Zhengdan 958) and rice (Huaidao 5) at three development stages under the increasing [CO2] followed the order of CK 0.05).
Toxicity of Chlorpyrifos-Based Pesticide Formulation Termicot® on Non-target Organism (Clarias gariepinus)

Chlorpyrifos is a highly toxic organophosphate pesticide used in agriculture. The surface run-offs from the use of this insecticide enter the aquatic ecosystem where it adversely affects fish and other aquatic organisms. This study was carried out to investigate the toxicity of Termicot® in the African cat fish, Clarias gariepinus. Before the 96 h acute toxicity testing, the physicochemical parameters of the water were analyzed. 250 juveniles of C. gariepinus with 2-4 cm length were exposed to varying concentrations of Termicot®. Range finding test was followed by 96 h acute toxicity test. The test fishes were exposed to sub-lethal concentrations representing one quarter and one eight of the LC50 for fifteen days. Blood samples were collected from exposed fish on the 5th, 10th and 15th days and evaluated for the presence of micronuclei. After various trials in the range finding test, it was observed that 2.00 mg/l killed 75% of the test fish species while 0.50mg/l killed 25%. The LC50 determined was 1.2811 mg/l. The frequency of induction of micronuclei significantly increased (P < 0.05) with increase of concentration and decreased with increase of the exposure period. It is recommended that Termicot® should be used where it is the only option, and it should be in controlled concentration.
THE DETERMINANTS OF INDIVIDUAL INTEREST TO BUY PRODUCT AT SHOPEE

Online buying and selling are increasingly recognized by the public and e-commerce are growing rapidly. E-commerce, like Shopee, can facilitate buying and selling process more effective and efficient. This study aimed to examine consumer intention in using Shopee application to buy a product. This is a quantitative study and data were collected using a survey method, namely a questionnaire. The data of this study were analyzed using the Statistical Product and Service Solutions (SPSS). The respondents of this study were 400 undergraduate students of the Faculty of Economics and Business, Universitas Brawijaya. The results showed that performance expectancy, social influence, facilitating conditions, hedonic motivation, and habit have a positive effect on behavioral intention. However, effort expectancy and price value are found insignificant on behavioral intention. Thus, it can be concluded that the higher the performace expectancy, social influence, facilitating conditions, hedonic motivation, and habit, the higher the effect on consumer interest to buy a product at Shopee.

Evaluation of Boosted Regression Tree for the Prediction of the Maximum 24-Hour Concentration of Particulate Matter

Air pollution is a considerable health danger to the environment. The objective of this study was to assess the characteristics of air quality and predict PM10 concentrations using boosted regression trees (BRTs). The maximum daily PM10 concentration data from 2002 to 2016 were obtained from the air quality monitoring station in Kuching, Sarawak. Eighty percent of the monitoring records were used for the training and twenty percent for the validation of the models. The best iteration of the BRT model was performed by optimizing the prediction performance, while the BRT algorithm model was constructed from multiple regression models. The two main parameters that were used were the learning rate (lr) and tree complexity (tc), which were fixed at 0.01 and 5, respectively. Meanwhile, the number of trees (nt) was determined by using an independent test set (test), a 5-fold cross validation (CV) and out-of-bag (OOB) estimation. The algorithm model for the BRT produced by using the CV was the best guide to be used compared with the OOB to test the predicted PM10 concentration. The performance indicators showed that the model was adequate for the next day’s prediction (PA=0.638, R 2 =0.427, IA=0.749, NAE=0.267, and RMSE=28.455).
Level of Adherence to GOLD Guidelines for Management of Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease: Is There a Difference Between Patient Management in Different Hospital Wards?

AbstractBackground: The purpose of this study was to evaluate the implementation of GOLD guideline in patients with an acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD). Methods: In a cross-sectional study, all patients with COPD exacerbation referred to Shariati hospital from January 2014 to March 2015 were investigated. The level of adherence to GOLD guideline in three areas of hospital admission, therapeutic components of inpatient management (pharmacologic treatments, respiratory support) and discharge plan was assessed via reviewing patients’ medical profile. Each subject was classified as complete, non-complete and not evaluated in terms of adherence to the guideline.Results: In this study, 125 patients with mean age of 67.64±1.71 years including 100 (80%) males were studied. Also, 104 and 21 patients were hospitalized in pulmonology and general medicine wards, respectively. In the present study, the adherence to GOLD recommendations for hospital admission, pharmacologic treatment and non-pharmacologic management were 92, 97.6 and 44.2%, respectively. Despite the high level of adherence to pharmacologic management, total adherence to non-pharmacologic interventions was poor.Conclusion: Although high level of adherence to pharmacological management of COPD was observed, there was overtreatment particularly in case of antibiotics prescription. In addition, non-pharmacological management was not considered in over half of the patients.
