The use of unit root and Box-Jenkins in Amman Stock Exchange (ASE)

This paper aims at examining the level of the efficiency of Amman Stock Exchange (ASE) on weak form, semi-strong form and strong form levels from January 2008 to December 2014. The paper concludes that there is a significant prediction performance of all ASE indices of the Jordanian market by using Box-Jenkins estimation. This result was confirmed by unit-root test since the return series for the five Jordanian indices failed to prove unit root

Impact of environment, culture, and sports tourism on the economy: a mediation-moderation model

The aim of this study is to investigate the direct relationship between the environment, culture, sports tourism and economy. Additionally, in this study, we have used sports tourism as a mediating variable in the relationship between environment, culture, and economy. Moreover, the moderating role of the destination image in the proposed relationships is examined. To validate the model, data obtained from 373 Malaysian Ministry of Tourism, Arts, and Culture employees is incorporated into structural equation modeling (SEM), PLS 4. According to the findings of this study, there is a positive and significant relationship between the environment, culture, sports tourism and the economy. Additionally, sports tourism mediates the relationship between the environment, culture, and a country’s economy. Interestingly, the study also found that destination image does not moderate the relationship between sports tourism and the economy. Overall, these findings highlight the importance of a healthy and culturally rich environment and the potential benefits of sports tourism for the economy. The findings of this research have important implications for policymakers and can be helpfully used in the tourism industry. In practical implications, fostering a healthy environment, preserving cultural heritage, and promoting sports tourism and destination image can boost the country’s economy

Thermal enhancement and numerical solution of blood nanofluid flow through stenotic artery

The blood flow through stenotic artery is one of the important research area in computational fluid mechanics due to its application in biomedicine. Aim of this research work is to investigate the impact of nanoparticles on the characteristics of human blood flow in a stenosed blood artery. In under consideration problem Newtonian fluid is assumed as human blood. Newtonian fluid flows through large blood vessels (more than 300 mu m). The constitutive equations together with the boundary conditions are diminished to non-dimensional form by using boundary layer approximation and similarity transfiguration to attain the solution of velocity and temperature distribution of blood flow through arterial stenosis numerically with the help of Matlab bvp4c. The results for physical quantities at cylindrical surface are calculated and their effects are also presented through tables. The heat transfer rate increases throughout the stenosed artery with the concentration of copper nanoparticle. Velocity curve decreases by increasing the values of flow parameter and nanoparticle volume fraction. Temperature curve increases due to increase in the values of nanoparticle volume fraction and decrease in Prandtl number.The work of U.F.-G. was supported by the government of the Basque Country for the ELKA-RTEK21/10 KK-2021/00014 and ELKARTEK22/85 research programs, respectively.

Characterization of bioactive fatty acids and oxidative stability of microwave vacuum dried fish powder supplemented extruded product

his study was aimed to determine the retention of bioactive fatty acids and oxidative stability of fish powder (FP) supplemented extruded products. The Labeo rohita fish meat was minced, microwave vacuum dried, and extruded. Product formulations containing FP (0-25%) and semolina (75-100%) were optimized using response surface methodology. The maximum bioactive fatty acids retention was 94.84% in the final product. The highest values of polyunsaturated fatty acids (PUFAs) were 87.97% and 85.66% at 25 °C for 30 and 60 days. Maximum TBARS values were 0.42 and 0.44 mg MDA/kg at 25 °C for 0 and 30 days, respectively. The highest carbonyl contents were 6.02, 7.67, 9.37 nmol/mg protein for 0, 30, and 60 days of storage at 25 °C, respectively. The moderate barrel exit temperature (125 °C) and feed moisture contents (20%) and high screw speed (150 rpm), FP (25%) exhibit the highest retention of PUFAs in a produc

Exploratory data analysis, classification, comparative analysis, case severity detection, and internet of things in COVID-19 telemonitoring for smart hospitals

he proportion of COVID-19 patients is significantly expanding around the world. Treatment with serious consideration has become a significant problem. Identifying clinical indicators of succession towards severe conditions is desperately required to empower hazard stratification and optimise resource allocation in the pandemic of COVID-19. Consequently, the classification of severity level is significant for the patient’s triaging. It is required to categorise the severity level as mild, moderate, severe, and critical based on the patients’ symptoms. Various symptomatic parameters may encourage the evaluation of infection seriousness. Likewise, with the rapid spread and transmissibility of COVID-19 patients, it is crucial to utilise telemonitoring schemes for COVID-19 patients. Telemonitoring mediation encourages remote data and information exchange among medicinal services, suppliers, and patients, furthermore, risk mitigation and provision of appropriate medical facilities. This paper provides explorative data analysis of symptoms, comorbidities, and other parameters, comparing different machine learning algorithms for case severity detection. This paper also provides a system (based on the degree of truthfulness) for case severity detection that might be utilised to stratify risk levels for anticipated moderate and severe COVID-19 patients. Finally, we provide a telemonitoring model of COVID-19 patients to ensure the remote and continuous monitoring of case severity progression and appropriate risk mitigation strategies

Heat transport investigation of engine oil based rotating nanomaterial liquid flow in the existence of partial slip effect

In this study, rotational nano liquid movement above a linearly stretching surface has been formulated. A two-phase model is used for this analysis. Base fluid engine oil and two distinct types of nanoparticles are used as nanoparticles, i.e. copper and aluminum oxide (Cu & Al2O3). This study is aimed to describe the changed possessions on velocity and temperature for rotational nanofluid flow above a linear enlarging surface in the existence of the slip effect. The leading structure of PDEs is converted into ODEs with a similarity transformation. Numerical findings are gained utilizing a sophisticated numerical approach. For both nanofluids, the results for rotational flow and heat transmission characteristics are emphasized with the help of graphs. At the linear extending surface, the influence of physical concentrations like heat flow rates and skin friction coefficients is investigated and visually clarified. Cunanoparticles proved to be better heat carriers than Al2O3 nanoparticles
