Derin Öğrenme Tekniklerini Kullanarak Akciğer X-Ray Görüntülerinden COVID-19 Tespiti

COVID-19 has spread rapidly all over the world and has become a global pandemic. This epidemic has a devastating impact on both public health and the global economy in everyday life. Detecting positive cases as early as possible is crucial to prevent the further spread of this epidemic and to treat affected patients quickly. Any tool that provides a fast and highly accurate diagnosis of COVID-19 infection is useful to experts. In this context, X-Ray tomographic imaging is an easily accessible alternative tool in the diagnosis of COVID-19. Recent developments using radiology imaging techniques show that such images contain interesting information about the COVID-19. The application of advanced artificial intelligence and machine learning techniques combined with radiological imaging can assist to accurate detection of this disease. Although X-Ray images can help to diagnose suspected cases early, various viral and bacterial pneumonia images are similar to COVID-19 and include similar features. Therefore, it is difficult for radiologists to distinguish similar lung diseases like viral and bacterial pneumonia from COVID-19. In this context, the similarity of COVID-19 symptoms to viral pneumonia can lead to misdiagnosis. In this study, deep learning techniques that can classify chest X-Ray images as COVID-19, normal and viral pneumonia are compared. In this study, 11 different deep learning techniques have been studied. Experimental studies of different techniques based on convolutional neural networks, which are popular today, have been studied on the same dataset to evaluate the performance of each technique and the best prediction method has been determined. In experimental studies, the highest accuracy value is obtained with the DenseNet121 model with 97.17%.
Personality traits an antecedent or consequences of workplace bullying

This study investigates whether Big Five personality traits are antecedents or consequences of bullying. A two-panel study designed in which panel one T1 data collected in one attempt and after a year panel, two T2 time data collected in the second attempt. Existing research on bullying found that individuals exposed to bullying experience an increase in conscientiousness and neuroticism and a decrease in agreeableness. It is claimed that the personality of the victim contributes to the bullying escalation process. There is still research scarcity whether personality is the cause of bullying or bullying results in personality change and another gap found in previous research was the lack of longitudinal research intended in shaping the individual antecedents or the impact of workplace bullying. By bridging these gaps, our study with simple random sampling collected data from university employees (N = 725). Manova test with repeated measures and structural equation modeling (SEM) analysis in AMOS was then used to examine and parallel many competing models to govern data fitness. Results found that experience of bullying in the first interval T1 leads to reduce in agreeableness and an increase in neuroticism in second interval T2. Managerial implication is also discussed.
Method validation for chemical composition determination by electron microprobe with wavelength dispersive spectrometer

The main goal of method validation is to demonstrate that the method is suitable for its intended purpose. One of the advantages of analytical method validation is translated into a level of confidence about the measurement results reported to satisfy a specific objective. Elemental composition determination by wavelength dispersive spectrometer (WDS) microanalysis has been used over extremely wide areas, mainly in the field of materials science, impurity determinations in geological, biological and food samples. However, little information is reported about the validation of the applied methods. Herein, results of the in-house method validation for elemental composition determination by WDS are shown. SRM 482, a binary alloy Cu-Au of different compositions, was used during the validation protocol following the recommendations for method validation proposed by Eurachem. This paper can be taken as a reference for the evaluation of the validation parameters more frequently requested to get the accreditation under the requirements of the ISO/IEC 17025 standard: selectivity, limit of detection, linear interval, sensitivity, precision, trueness and uncertainty. A model for uncertainty estimation was proposed including systematic and random errors. In addition, parameters evaluated during the validation process were also considered as part of the uncertainty model.
Quantum Effects on the Capacitance of Graphene-Based Electrodes

Quantum capacitance has been recently measured for electric double layers (EDL) at electrolyte/graphene interfaces. However, the importance of quantum capacitance in realistic carbon electrodes is not clear. Toward understanding that from a theoretical perspective, here we studied the quantum capacitance and total capacitance of graphene electrodes as a function of the number of graphene layers. The quantum capacitance was obtained from electronic density functional theory based on fixed band approximation with an implicit solvation model, while the EDL capacitances were from classical density functional theory. We found that quantum capacitance plays a dominant role in total capacitance of the single-layer graphene both in aqueous and ionic-liquid electrolytes but the contribution decreases as the number of graphene layers increases. The total integral capacitance roughly levels off and is dominated by the EDL capacitance beyond about four graphene layers. Because many porous carbons have nanopores with .

Water, Sanitation and Hygiene Resources Available at Higher Education Institutes of Sindh and Students’ Satisfaction

Mehran University Research Journal of Engineering and Technology Vol. 40, No. 2, 383 - 391, April 2021 p-ISSN: 0254-7821, e-ISSN: 2413-7219 DOI: 10.22581/muet1982.2102. 12 This is an open access article published by Mehran University of Engineering and Technology, Jamshoro under CC BY 4.0 International License. 383 Water, Sanitation and Hygiene Resources Available at Higher Education Institutes of Sindh and Students’ Satisfaction Ubed Ur Rehman1a, Jamil Ahmed1b, Rasool Bux Maher1c, Aneela Yasmeen2RECEIVED ON 13.02. 2019, ACCEPTED ON 03.05. 2019 ABSTRACT The present study was focused on the available Water, Sanitation and Hygiene (WASH) facilities and students’ satisfaction in three public and two private Higher Education Institutes (HEIs) of Hyderabad and Jamshoro city. This cross-sectional study recorded WASH facilities in 21 departments of 5-HEIs and satisfaction appraisal of 630 students in total. The survey was also supplemented with quality analysis of Point of Use (PoU) drinking water. The results revealed that the overall 85.7 and 47.6% contamination of the drinking water samples were recorded due to total and thermo-tolerant coliforms, respectively. Further, physiochemical parameters were found in the permissible limits as provided by the World Health Organization (WHO) and arsenic was not detected in any of the water samples. In total 25% of the toilet facilities were found non-functional. All monitored HEIs were found having sufficient quantity of water however, 95% hand-washing stations did not supply soap/ detergent for hand-washing. Moreover, this study divulges that there is a significant relationship between WASH facilities like water quality (χ2= 7.55*; p=0.023), toilets functioning (χ2= 45.39**; p=0.002), and washing facilities (χ2= 37.29**; p=0.000) in HEIs and student’s satisfaction in HEIs. Thus, it can be concluded that the poor WASH facilities in HEIs could affect the students’ satisfaction leading to affect their performance in the studies, negatively.
The Moderating Role of Natural Resources Between Institutional Quality and CO2 Emissions: Evidence From Developing Countries

The recent study aim is to scrutinize the moderating role of natural resources between institutional quality and carbon dioxide (CO2) emissions in 106 developing countries from 1996 to 2017 by using dynamic fixed effect, generalized method of moments (GMM) and system generalized method of moments (system GMM) estimators as well as apply the instrumental fixed effect, the instrumental time fixed effect and instrumental system GMM estimators as robustness. We make use of dynamic models and instrumental system GMM to reduce the result of autocorrelation increasing from misspecification of a model as well as clear the biases from unnecessary data and solve the possible endogeneity issues. The empirical results indicate that financial development, trade, and institutional factors: corruption perception control, government effectiveness, political stability, regulatory quality, rule of law, and voice and accountability play a vital role in CO2 emissions reduction but natural resources along with economic growth are the core factors that cause CO2 emission in developing countries. On the opposing, natural resources boost the indirect impact of institutional quality on CO2 emissions in developing countries.
A Demand-Based Analysis of Ecotourism Product Diversification in Botswana

The evolution of the tourism sector has been subjected to massive changes in demand and technology, as well as increasing competition amongst destinations to such a degree that product diversification is now core to development strategies in order to maintain competitiveness and remain abreast of contemporary trends. The study sought to determine the demand for ecotourism products in view of developing a diversification strategy. Self-administered questionnaires were used to collect demand-side data at Maun and Kasane airports; these data were then analysed quantitatively. Findings revealed a strong preference for wildlife/wilderness and nature products, whereas events and hunting were least liked. The country attracts mature tourists who prefer soft adventure and activities that prioritize conservation, interpretation, and environmental education. Factors related to entertainment, the construction of entertainment facilities, a post office, and golf courses were strongly resented. It was established that related diversification, focused on expanding services and enhancing existing products, is the most appropriate strategy. Practically, the research offers a specific diversification strategy based on ecotourism, detailing how and what to diversify. The study makes a valuable contribution to demand-side diversification literature as well as empirical research, which is lacking in Botswana.
The precarious: how American voters view the working class

ABSTRACT The idea of the working class is often employed in political dialogue, yet its definitions are fraught. Working class has been identified with occupation, education, income or self-identification. We argue that economic precarity is an important aspect of working class status that is often not directly captured by other measures. We find that when asked, voters often suggest precarity as a defining characteristic of working class in the United States. Next, we show that high levels of economic precarity predict self-identifying as liberal, a Democrat, and disapproving of President Donald Trump even while controlling for an individual’s race, gender, age, education and income. We also find that precarity has a persistent effect for white and non-white voters. Overall, we show that by ignoring precarity as an aspect of the working class, researchers are missing important aspects of how working class status is conceived in the United States.
New As2S3:Pr3* - polymer composite materials

New composite materials consisting from arsenic sulphide (As 2 S 3 ) doped with rare-earth ions (Pr 3+ ) and polyvinyl alcohol (PVA) were prepared and investigated. The optical absorption spectra of thermally evaporated amorphous thin films of As 2 S 3 :Pr 3+ correlate with the transmission spectra of bulk glasses. For the samples As 2 S 3 :Pr 3+ /PVA an increasing of transparency in the visible region with respect to pure As 2 S 3 was observed. The investigated new composites are perspective for different photonic devices as well as for recording media with high resolution.
The event-focused interview: what is it, why is it useful, and how is it used?

ABSTRACT There has been longstanding interest in understanding how people think, feel, and behave in sport and exercise activities. Although naturalistic recordings, momentary assessments, and post-event questionnaires have been employed to capture information on people’s experiences, these methods can have some shortcomings for researchers interested in advancing knowledge of certain social-psychological phenomena, especially in natural settings. The purpose of this paper is to describe the event-focused interview method and outline its utility for researchers who are interested in capturing rich, in-depth information on episodic phenomena, such as particular moments, events, psychological states, and experiences. First, we describe the event-focused interview method and the background to its development. Second, we highlight the limitations of naturalistic recordings, existing momentary assessment methods, and post-event questionnaires for certain types of research, before explaining why event-focused interviews can add to the suite of methods researchers use to obtain information on episodic phenomena in specific sport and exercise activities. Third, we provide guidance on how the event-focused interview method can be implemented, using illustrative examples from several recent event-focused interview studies. Fourth, to guide researchers in future, we identify some methodological dilemmas and considerations for applying this method. We conclude by outlining several methodological avenues that could be employed in future event-focused interview studies. Overall, we propose that the event-focused interview method may be a promising addition to the collection of methods available to researchers interested in generating new theoretical and practical knowledge about episodic phenomena in sport and exercise.
Predicting soil workability and fragmentation in tillage: a review

Soil workability and friability are required parameters to consider when creating suitable seedbeds for crop establishment and growth. Knowledge of soil workability is important for scheduling tillage operations and for reducing the risk of tillage‐induced structural degradation of soils. A reliable evaluation of soil workability implies a distinctive definition of the critical water content (wet and dry limits) for tillage. In this review, we provide a comprehensive assessment of the methods for determining soil workability, and the effects of soil properties and tillage systems on soil workability and fragmentation. The strengths and limitations of the different methods for evaluating the water content for soil workability, such as the plastic limit, soil water retention curve (SWRC), standard Proctor compaction test, field assessment, moisture‐pressure‐volume diagram, air permeability and drop‐shatter tests are discussed. Our review reveals that there is limited information on the dry limit and the range of water content for soil workability for different textured soils. We identify the need for further research to evaluate soil workability on undisturbed soils using a combination of SWRC and the drop‐shatter tests or tensile strength; (i) to quantify the effects of soil texture, organic matter and compaction on soil workability; and (ii) to compare soil water content for workability in the field with theoretical soil workability, thereby improving the prediction of soil workability as part of a decision support system for tillage operations.
Anaerobic removal of COD in metal-cutting-fluid wastewater

The treatment of metal-cutting-fluid wastewater was investigated using an anaerobic, granular activated carbon, fluidized-bed process. During 900 days of operation, three influent COD concentrations were tested: 1029, 3343, and 5324 mg/L. For each influent COD concentration, a series of influent flow rates was used to test a range of unexpanded empty-bed contact times from 0.9 to 7.5 hours. The findings include the following: (1) the reactor removed biodegradable COD effectively and efficiently at relatively high loading rates (more than 70 kg/m 3 .d); (2) approximately 35% of the influent COD was nonbiodegradable − more than approximately 65% of the nonbiodegradable COD was aerobically biodegradable; (3) approximately 68% of the COD biodegraded was converted to methane, showing potential for energy recovery
Dual-view light-sheet imaging through a tilted glass interface using a deformable mirror

Light-sheet microscopy has become indispensable for imaging developing organisms, and imaging from multiple directions (views) is essential to improve its spatial resolution. We combine multi-view light-sheet microscopy with microfluidics using adaptive optics (deformable mirror) which corrects aberrations introduced by the 45o-tilted glass coverslip. The optimal shape of the deformable mirror is computed by an iterative algorithm that optimizes the point-spread function in two orthogonal views. Simultaneous correction in two optical arms is achieved via a knife-edge mirror that splits the excitation path and combines the detection paths. Our design allows multi-view light-sheet microscopy with microfluidic devices for precisely controlled experiments and high-content screening.

Energy and CO2 emission reduction potential from investment in energy efficiency building retrofits in Bangkok, Thailand

ABSTRACT A major barrier to the widespread adoption of energy efficiency is the lack of understanding of the benefits - the investment opportunity (the returns), the cost savings, and environmental. We assess the potential of retrofits in commercial buildings in Bangkok using case studies and existing property information. The aim is to provide insights for policy makers, building owners, and investors on the potential to reduce energy consumption and costs, and greenhouse gas emissions. Our findings suggest that by undertaking energy efficiency retrofits in Bangkok, there is the potential to reduce energy costs by approximately US123 million and reduce over 500,000 tons of CO2 emissions per year, presenting an investment opportunity of approximately US300 million, with a payback of 3.49 years.
Knowledge order in an online knowledge community: Group heterogeneity and two paths mediated by group interaction

Knowledge order in an online knowledge community (OKC) refers to a consensual version of collective knowledge in the creation of shared knowledge representation. Much previous research has been conducted in the context of the ordered structure of objective knowledge systems, but this does little to explain the microlevel order of knowledge after users contribute knowledge and achieve consensus through online interactions in OKC. Based on interactive team cognition theory and the stigmergy coordination mechanism, our research aims to investigate how knowledge and experience heterogeneity affect knowledge order effectiveness and efficiency through collaborative and communicative interaction. To test our hypotheses, we randomly collected the records of 250 articles from the English version of Wikipedia. Partial least squares structural equation modeling indicated that OKC favoring online collective knowledge order by limiting communicative interaction, as collaborative interaction is very effective in achieving knowledge order and in achieving it in a fast way. From our findings, scholars and practitioners are advised to pay attention to online knowledge order in the management and design of OKC.

Influence des facteurs naturels sur la maturation du raisin, en 1979, à Pomerol et Saint-Emilion

Les vignobles de Pomerol et Saint-Emilion sont implantes sur des sols derivant de roches-meres variees; ils produisent des vins de haute qualite mais differents suivant leur origine geologique.Dans les meilleurs crus, nous avons pu verifier que les variations mesoclimatiques sont tres faibles et ont peu d'influence sur les caracteres des vins. Par contre, en 1979, une relation a ete mise en evidence entre les conditions de l'alimentation en eau de la vigne (etroitement liees aux proprietes physiques des sols) et la constitution des raisins a maturite (V. vinifera var. Merlot noir). +++The vineyards of Pomerol and Saint-Emilion (France) are established on soils derived from different parent materials; they produce wines of high quality, which differ according to the geological origin of the soil.In the better vineyards, variations in the mesoclimates are small and have little influence on the characters of the wines. But, in 1979, a relationship was established betwen the conditions of wateruptake by Vitis vinifera (var. Merlot noir) and the composition or the grape at maturity.
