Abstract \nIntroduction, \nThis current study examines the factors that contribute towards behavior change among motorcyclist and its implications in encouraging the use of crush helmets in Accra the capital city of Ghana. \nMethods \nIn this study the result primarily is based on collected data from using questionnaire randomly administered to motorcyclists in two specific municipalities in the greater Accra Region who ride motorcycles either for private or for commercial use.\nResults\nThe theory of Planned behavior was used and the results indicate that of the four variables in the framework only perceived behavioral control was seen to contribute towards changing risky behaviors of motorcyclists as it was found to have a significant positive relationship with intention to change and change with helmet wearing. Again, the moderating role of social marketing campaigns was found to have a rather negative influence indicating the lack of or inadequate use it. \nConclusions\nThe argument therefore is that social marketing campaigns should be intensified so as to educate motorcyclists on the need to use helmets to serve as protection even where when there is an accident. This will prevent head injuries in the event of road crush.

It is known fact that the temperature indicated by a temperature probes inserted in airflow depends on the thermodynamic temperature, velocity of external flow, isobaric heat capacity of fluid and on the recovery coefficient of the probe. That dependence is essential for the external velocity measurement by the method of Recovery Temperature Anemometry (RTA). Even if the recovery coefficient of the probe and isobaric heat capacity are known, we also have to know the velocity of external flow for the evaluation of thermodynamic temperature or, on the other hand, we have to know the thermodynamic temperature for the evaluation of velocity. That means we have two unknown properties in the real condition measurements – thermodynamic temperature and the velocity. This article deals with the possible solution of mentioned problem. By using of two probes with a different recovery coefficient, the need of knowledge the thermodynamic temperature is eliminated and a combination of two temperature probes with a different recovery coefficient could be used for the velocity measurement.

Background: \n\nIn spite of many years of rigorous exploration and several papers after Modigliani and Millers\' original work, surprisingly there is absence of agreement even today among the finance specialists on the fundamental issue of corporate finance, concerning why finance managers utilize various combinations of debt and equity. Most of the researchers opine differently as to what is the ideal debt and equity formation, which can maximize the profitability of the origination. \n\nThe degree of collision of capital structure on profitability as well as to scrutinize the model debt and equity structure in the selected IT companies of India is the prime intent of the study. We have chosen the top five IT companies of India from the period 2014-2015 to 2018-19 based on market capitalisation. Different analysis such as Proportion Analysis, Correlation Analysis and Regression Analysis are taken into consideration to find out the noteworthy association between the debt-equity mix and profitability of companies. \n\nFindings:\n\nThe after-effects of correlation examination show that, both DER and DTA have a negative relationship with NP, though not significantly, while both DER and DTA have a significant negative relationship with ROA. Nevertheless, all other profitability factors for example ROCE, RONW and RLTF have a strong and positive relationship with DER and DTA, which may be a result of the advantage of trading on equity dealt in by the organization. As the study based on the experimental variability’s such as NP, ROCE, RONW, ROA and ROLF, with the predictor variable as Debt Equity Ratio (DER) and Debt to Total Assets Ratio (DTA), taken together to establish the association with capital structure. After the analysis, results shows that, the R² esteems as computed in the regression examination are 22.9%, 88.4%, 93.1%, 71.8% and 88.7%. It demonstrates that; expect Net Profit, which shows a moderate positive relationship but other variables show a strong positive relationship with capital structure.

The purpose of the study is to determine the structure of technology for the use of video content for linguistic and cultural adaptation of foreign students at higher education institutions of the USA from psycholinguistic point of view. The article is concerned with the analysis of practical measures aimed at forming and developing communication and socio-cultural competence when using video content, including professionally-oriented video content. In the course of the research, the level of influence of video content on the development of foreign students\' linguistic and social skills, which are necessary for a comprehensive communication with cultural elements, was determined using the descriptive method. Comparative historical and typological methods allowed to determine whether foreign students could identify any historical and linguistic changes in the language they learned, as well as make a comparative analysis of native and foreign languages. The impact of video content used during adaptation activities was analyzed using sociolinguistic methods, namely the field research method aimed at the identification of a direct correlation between film screenings and the development of the ability to use linguistic and cultural patterns in foreign students, as well as the method of sociolinguistic research which helped to conduct a more detailed study of the socio-communicative elements formed and the impact that the cultural specifics of the society had on them. The applied linguistic method helped to conduct a more detailed study of the impact of video text on the communication skills of a person. Linguistic and cultural patterns are an important component of successful communication for a foreign student since it provides them with elements that can be put to use when needed in social relations. One of the most widely used methods for forming such patterns at HEI of the USA is the use of video content which involves screenings of American films (for direct acculturation, when a foreign student adapts to the linguistic and cultural specifics of the host country) and films produced in the countries from which students came (for reverse acculturation, when local students adapt to the socio-cultural specifics of foreign students). The use of video content in acculturation activities helps a foreign student develop not only linguistic and cultural patterns that are necessary for academic and social activities in the host country, but also critical thinking, which facilitates analysis of new socio-cultural and linguistic information, thereby preventing the negative effects of culture shock. Moreover, video content can be presented with a twofold purpose, as it may be socioculturally oriented (presenting cultural specifics or social problems of the host country) and professionally oriented (containing specialized vocabulary); it can also provide the opportunity for direct and reverse acculturation.

The aggregation operators (AOs) play an important role in the fuzzy information system. The aim of this research work is to established a new type of aggregation operators based on Hamacher operational law of Fractional orthotriple fuzzy uncertain linguistic numbers (FOFULNs). First, we define Fractional orthotriple fuzzy uncertain linguistic sets (FOFULSs), and develop some operational law of FOFULSs. Further, extended these operational law to AO and developed Fractional orthotriple fuzzy uncertain linguistic Hamacher averaging and geometric aggregation operators. Then, we find properties of developed operator and their related shape. In order to give an application of the introduced operators, we first constrict a system of multi-criteria decision making algorithm. Then, we constrict a logistics provider selection problem under the FOFUL information.

With rapidly changing technology, people have more and more requirements for thermal comforts regarding indoor temperature, humidity, and wind speed, and pay more attention to air quality. Indoor air quality has serious effects on the elderly, children, and those with respiratory allergies. Based on the architecture of the Internet of Things (IoT) smart home, this study constructed an indoor air quality monitoring system to explore how people can live in an environment with good air quality. Among the numerous air quality indices (AQIs), the carbon dioxide (CO2) index and AQI of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) are selected as the indices suitable for this study. The common points of the two indices are combined, and then, based on the data of the Environmental Protection Administration, indoor and outdoor environmental parameters are analyzed, and controllable environment variables are simulated to analyze their effects on air quality. This study designed effective load control using fuzzy control and developed a fuzzy rule base for simulation of the environment variables. Decision logic was used to replace the threshold control of indoor air quality (IAQ) in the past, and a comfortable air quality monitoring system was designed by combining the Arduino Uno development board and E ESP8266 Wi-Fi wireless transmission modules.

The requirement for the expanding Universe to be a closed thermodynamical system at every moment of its evolution leads to the behaviour consistent with the R = ct cosmological model. The total gravitational mass of the Universe increases linearly with time, while its gravitational potential remains constant. In such a universe, the Second Law is a direct consequence of the continuous mass generation within the Universe. The entropy value of the Universe equals the Bekenstein-Hawking entropy of the corresponding black hole. The current entropy value of the Universe has been computed and validated against the value obtained by another independent method. The temperature of the Universe varies inversely proportional to the square root of time. An exact solution for the temperature evolution has been derived and validated against the observed value of the cosmic microwave background temperature. The conservation laws within the Universe are independent of its energy content and, whatever the initial geometry of the Universe is, it flattens in the course of expansion very fast � this follows from the non-field solution obtained for the Schr�dinger wave function of the Universe. To obtain all the results, reported in this study, no assumption about the dark energy is needed.

Customer experience is one of the most fundamental concepts in marketing literature which results in hedonic & memorial experience for customers. In-store experience is an important phenomenon that increasingly attracts the professional marketing experts and academics around the world and can use them as a distinctive tool in the stores. The methodology of this study is based on descriptive and mixed method. The qualitative part of this study which was based on phenomenological method began with protocol design on the basis of systematic studies & then through eighteen individual deep interviews. With multiple purposive sampling professional shoppers were selected and then three types of coding include open coding, axial coding and selective coding in ATLAS.ti software are used to determine the themes and categories. In quantitative part of this study, 298 shoppers were selected randomly and standardized questionnaires were distributed among them. Lisrel software was used for data analysis. The results convey that antecedents of in-store experiences (perceived values, word of mouth, brand equity, layout and design, employee’s skills, facilities) have a positive and significant relationship with consequences (purchase satisfaction, repurchase intention and flaneur).

Future mechanical frameworks will be arranged in exceptionally organized conditions where they speak with modern control frameworks, cloud administrations or other systems at distant areas. In this pattern of solid digitization of modern frameworks (likewise some of the time alluded to as Industry 4.0), computerized attacks are an in-wrinkling peril to the uprightness of the robotized systems at the focal point of this new unforeseen development. It is typical, that the Robot Operating System (ROS) will expect a noteworthy capacity in cutting edge mechanics outside of unadulterated investigation arranged circumstances. ROS at any rate has important security issues which ought to be tended to before such things ought to show up at mass business parts. In this paper we present the most notable shortcomings of ROS, attack vectors to abuse those and a couple of approaches to manage secure ROS and similar systems. We advise the most ideal approach to ensure about ROS on an application level and portray an answer which is composed clearly into the ROS place. Our proposed plan has been executed and attempted with late types of ROS, and adds security to all correspondence channels without being nosy to the system bit itself.
